[0004] As living standards improve, consumers' demand for long-distance photography is increasing.

[0005] Telephoto camera modules typically have a long focal length, enabling clear images of distant subjects.

[0197] A telephoto camera module is a camera module with a long focal length, capable of clearly capturing distant subjects. However, due to its relatively long focal length, a telephoto camera module requires a long total optical lens length (TTL), resulting in a relatively large size. Furthermore, a camera module typically requires optical focus and / or optical image stabilization, which increases the size of the telephoto camera module, making it unsuitable for assembly into small mobile devices.

[0198] The present application provides a solution to the above-mentioned problem, which miniaturizes the camera module and makes it suitable for being installed in a small mobile device.

[0199] Figures 1 to 15 illustrate a camera module 1 according to some embodiments of the present application. The camera module 1 includes an optical lens 10, a light deflecting element 30, a photosensitive component 40, and a drive device 60. The light deflecting element 30 is disposed between the optical lens 10 and the photosensitive component 40, so that light incident on the optical lens 10 is reflected at least once within the light deflecting element 30 before reaching the photosensitive component 40. The light deflecting element 30 folds the light emitted from the optical lens 10 and guides it to the photosensitive component 40, thereby forming an image through the photosensitive component 40 to obtain image information. It is worth noting that the light deflecting element 30 is in an elongated strip shape, so that light can be reflected multiple times within the light deflecting element 30, thereby folding the optical path multiple times. In the present application, the position of one or more components in the optical lens 10, the light deflecting element 30 or the photosensitive component 40 in the camera module 1 can be adjusted to achieve the optical focus and / or optical image stabilization function of the camera module 1. For example, the driving device 60 can be configured to drive one or more components in the optical lens 10, the light deflecting element 30 or the photosensitive component 40 to move.

[0200] The optical lens 10 has an optical axis. Light incident along the optical axis is reflected at least once within the light deflection element 30, that is, the light is deflected from propagating along the optical axis to propagating in another direction approximately orthogonal to the optical axis, and finally emitted along the optical axis to reach the photosensitive component 40. For ease of description, a rectangular coordinate system is established, with the Z axis approaching the optical axis of the optical lens 10 or being parallel to the optical axis of the optical lens 10, the Z axis being perpendicular to the plane containing the X axis and the Y axis, the X axis and the Y axis being perpendicular to each other, the XOY plane containing the X axis and the Y axis being also referred to as the horizontal plane, the X axis being the length direction of the camera module 1, the Y axis being the width direction of the camera module 1, and the Z axis being the height direction of the camera module 1. It should be understood that in the embodiments of the present application, the optical axis of the optical lens 10 is also referred to as the optical axis of the camera module 1.

[0201] As shown in Figures 1 to 2B, the light deflecting element 30 includes multiple reflective surfaces. The light emitted by the optical lens 10 is reflected multiple times on the multiple reflective surfaces of the light deflecting element 30. After being emitted by the light deflecting element 30, the light reaches the photosensitive component 40. The photosensitive component 40 and the optical lens 10 are arranged on the same side of the light deflecting element 30. Therefore, the height dimension of the camera module 1 only needs to consider the sum of the height dimension of one of the photosensitive component 40 and the optical lens 10 and the height dimension of the light deflecting element 30, without having to simultaneously superimpose the heights of the optical lens 10, the light deflecting element 30 and the photosensitive component 40. In this way, the height dimension of the camera module 1 can be reduced. In a specific example, the optical lens 10 and the light deflecting element 30 form an "L"-shaped structure, and the photosensitive component 40 is arranged in the corner space formed by the optical lens 10 and the light deflecting element 30. The height dimension of the optical lens 10 is greater than the height dimension of the photosensitive component 40, and the top surface of the optical lens 10 is higher than the top surface of the photosensitive component 40. In this way, the photosensitive component 40 does not affect the height of the camera module 1, wherein the top surface of the optical lens 10 and the top surface of the photosensitive component 40 respectively refer to the side thereof away from the light deflecting element 30.

[0202] The optical lens 10 includes a lens barrel 12 and at least one optical lens 11 housed therein. The optical lens 10 collects light from a subject and transmits it to a light deflecting element 30. The optical lens 10 has an optical axis that is perpendicular to the light deflecting element 30. In one specific example, as shown in Figures 2A and 2B, the optical lens 10 includes three optical lenses 11: a first lens L1, a second lens L2, and a third lens L3, arranged along the direction of incident light. The first lens L1, the second lens L2, and the third lens L3 are fixed to the lens barrel 12, thereby maintaining the spacing between the three optical lenses 11. It is worth noting that in one embodiment of the present application, the diameter of the inner wall of the lens barrel 12 decreases along the direction of incident light, thereby gradually decreasing the diameter of the at least one optical lens 11 in the lens barrel 12 along the direction of incident light. Therefore, during assembly of the optical lens 10, the at least one optical lens 11 is installed into the lens barrel 12 in increasing order of diameter. For example, the third lens L3 can be installed in the lens barrel 12 first, then the second lens L2 can be installed in the lens barrel 12, and finally the first lens L1 can be installed in the lens barrel 12, wherein glue and / or a pressure ring are provided between the peripheral side of the first lens L1 and the inner wall of the lens barrel 12 to fix the three optical lenses 11 in the lens barrel 12.

[0203] In one embodiment of the present application, the camera module 1 further includes a compensating lens group 20, which can be disposed between the optical lens 10 and the light deflecting element 30. The compensating lens group 20 can further modulate the light emitted from the light deflecting element 30. For example, the compensating lens 21 can further converge the light emitted from the light deflecting element 30 to reduce the back focus, thereby achieving the purpose of reducing the size of the camera module 1. In a specific example, the compensating lens group 20 includes a compensating lens 21, which is fixed to the light-emitting side of the optical lens 10 by gluing. For example, the compensating lens 21 is fixed to the bottom side of the lens barrel 12 by gluing (the bottom side of the lens barrel 12 refers to the side of the lens barrel 12 close to the light deflecting element 30). Since the compensating lens 21 is not fixed in the lens barrel 12, the diameter of the compensating lens 21 can be larger than that of one of the at least one optical lens 11 of the optical lens 10. Therefore, the compensating lens 21 has greater design freedom.

[0204] The photosensitive assembly 40 includes a chip circuit board 42, a photosensitive chip 41 electrically connected to the chip circuit board 42, and at least one electronic component 43. The photosensitive surface of the photosensitive chip 41 faces the light deflection element 30 to receive light emitted from the light deflection element 30. In one specific example, the photosensitive chip 41 is fixed to the side of the chip circuit board 42 facing the light deflection element 30. The at least one electronic component 43 can be implemented as a passive electronic device such as a capacitor or resistor, or an active electronic device such as a diode or memory chip. The at least one electronic component 43 can be disposed on the side of the chip circuit board 42 facing the light deflection element 30 or on the other side away from the light deflection element 30.

[0205] Furthermore, in some embodiments of the present application, the camera module 1 further includes a filter assembly 50, which is disposed on the optical path of the light, and the camera module 1 can filter out unnecessary stray light (such as infrared light) through the filter assembly 50. In one embodiment of the present application, the filter assembly 50 is disposed between the light deflection element 30 and the photosensitive component 40. For example, in a specific example, the filter assembly 50 includes a filter element 51 and a filter element bracket 52 for supporting the filter element 51. The filter element 51 is supported on the filter element bracket 52 by, for example, gluing. Both sides of the filter element bracket 52 are respectively fixed to the chip circuit board 42, so that the filter assembly 50 is disposed between the light deflection element 30 and the photosensitive chip 41. In other embodiments of the present application, the filter component 50 can be arranged in the light deflecting element 30 and / or the optical lens 10. For example, the filter component 50 can be implemented as a layer of filter film, which is attached to a surface of the light deflecting element 30, or the filter film is attached to the surface of at least one optical lens 11 of the optical lens 10, thereby achieving the function of filtering out infrared light.

[0206] In the present application, as shown in Figures 2A to 3B , the light deflecting element 30 has multiple reflective surfaces, allowing light entering the light deflecting element 30 to undergo multiple reflections. This effectively increases the optical TTL, making the camera module 1 suitable for capturing distant objects and providing high-quality images of these distant objects. TTL refers to the distance on the optical axis between the front vertex of the light-entering side (facing the subject) of the optical lens 10 of the camera module 1 and the image plane at the photosensitive component 40.

[0207] Typically, increasing the TTL increases the size of the camera module 1, making it unsuitable for integration into small mobile devices. In one embodiment of the present application, the light deflecting element 30 extends horizontally, meaning its horizontal length is greater than its height or thickness. This allows the light deflecting element 30 to maintain a low height or thickness when light is reflected multiple times within the light deflecting element 30, thereby preventing an increase in the height of the camera module 1. In other words, the horizontal length of the light deflecting element 30 is greater than its height, allowing the height of the camera module 1 to be reduced while maintaining effectiveness, thereby meeting the need for miniaturization of the camera module 1.

[0208] In one embodiment of the present application, the number of times light is reflected in the light deflecting element 30 is an odd number, and the photosensitive component 40 and the optical lens 10 are centrally arranged on the same side of the light deflecting element 30. Light passing through the optical lens 10 is reflected an odd number of times in the light deflecting element 30 before being emitted to the photosensitive component 40. In another embodiment of the present application, the number of times light is reflected in the light deflecting element 30 is an even number, and the photosensitive component 40 and the optical lens 10 are respectively arranged on opposite sides of the light deflecting element 30. Light passing through the optical lens 10 is reflected an even number of times in the light deflecting element 30 before being emitted to the photosensitive component 40.

[0209] Specifically, in one embodiment of the present application, the light deflecting element 30 includes at least four surfaces, at least three of the at least four surfaces are reflective surfaces, and the light is reflected on the at least three reflective surfaces in the light deflecting element 30. For example, the light deflecting element 30 includes a trapezoidal prism, and the cross-section of the light deflecting element 30 is a trapezoid. When the light deflecting element 30 includes three reflective surfaces, the light is reflected three times in the light deflecting element 30; when the light deflecting element 30 includes four reflective surfaces, the light is reflected five times or four times in the light deflecting element 30, which will be described in detail later in this application. Of course, in other embodiments of the present application, the light deflecting element 30 may include prisms of other shapes, such as triangular prisms, pentagonal prisms, hexagonal prisms, etc., and still provide the above-mentioned light deflection function and design benefits, and this application does not limit this.

[0210] As shown in Figures 2A and 2B, in one embodiment of the present application, the light deflecting element 30 is implemented as a trapezoidal prism, and the light deflecting element 30 includes four surfaces, for example, a first surface 31, a second surface 32, a third surface 33, and a fourth surface 34. The plane on which the first surface 31 is located is parallel to the plane on which the third surface 33 is located, the length of the third surface 33 is less than the length of the first surface 31, and the plane on which the second surface 32 is located intersects with the plane on which the fourth surface 34 is located. Among them, at least three of the four surfaces of the light deflecting element 30 have a reflective function, for example, the first surface 31, the second surface 32, and the fourth surface 34 are reflective surfaces that have a reflective function and can reflect light; or the first surface 31, the second surface 32, the third surface 33, and the fourth surface 34 are reflective surfaces that have a reflective function and can reflect light.

[0211] In a specific example, the angle between the second surface 32 and the first surface 31 is an acute angle, the angle between the fourth surface 34 and the first surface 31 is an acute angle, the angle between the second surface 32 and the third surface 33 is an obtuse angle, and the angle between the fourth surface 34 and the third surface 33 is an obtuse angle. The angle between the second surface 32 and the first surface 31 may be in the range of 25° and 35°, and the angle between the fourth surface 34 and the first surface 31 may be in the range of 25° and 35°. It should be understood that the angles between the various surfaces of the light deflecting element 30 can control the reflection angle of light when it is reflected within the light deflecting element 30, thereby realizing the function of the light deflecting element 30 to perform multiple reflections on light.

[0212] Furthermore, the light deflection element 30 is an isosceles trapezoidal prism. As shown in the cross-sectional view of the trapezoidal prism, the second surface 32 and the fourth surface 34 are of equal length, and the second surface 32 and the fourth surface 34 are axially symmetrical. The angle between the second surface 32 and the first surface 31 is equal to the angle between the fourth surface 34 and the first surface 31, and the angle between the second surface 32 and the third surface 33 is equal to the angle between the fourth surface 34 and the third surface 33. It should be understood that because light undergoes multiple reflections within the light deflection element 30, even a slight change in the angle between the second surface 32 and the fourth surface 34 will affect the light reflection. When the second surface 32 and the fourth surface 34 are symmetrically arranged, as much incident light as possible, after multiple reflections, exits the light deflection element 30 and reaches the photosensitive component 40, minimizing light loss. In one specific example, the optical axis of the incident light is axially symmetrical along its optical path within the light deflection element 30.

[0213] In one embodiment of the present application, the second surface 32, the fourth surface 34, and / or the third surface 33 of the light deflecting element 30 may be provided with a reflective coating, or a reflector may be provided, so that light can be reflected on the second surface 32, the fourth surface 34, and / or the third surface 33. For example, in a specific example of the present application, the reflective coating may include a mirror coating based on a thin metal layer, a film with a white inner surface, etc. Further, at least a portion of the first surface 31 of the light deflecting element 30 is provided with the reflective coating, and at least a portion of the first surface 31 is not provided with the reflective coating, so that the first surface 31 can transmit light or allow light to pass through the first surface 31. Furthermore, the first surface 31 can also reflect light under the phenomenon of total internal reflection.

[0214] It should be understood that total internal reflection can occur when the incident angle of light approaches or exceeds a certain limiting angle (called the critical angle). The incident angle refers to the angle between the light incident on a surface and a line perpendicular to the surface at the point of incidence (called the normal). Therefore, when the incident angle of light is less than the critical angle, the first surface 31 of the light deflecting element 30 allows the light to pass through. When the incident angle of light approaches or exceeds the critical angle, the first surface 31 of the light deflecting element 30 reflects the light at the corresponding surface.

[0215] Specifically, in one embodiment of the present application, the first surface 31 includes a light entrance area 311, a light exit area 312, and a reflective area 313 disposed between the light entrance area 311 and the light exit area 312. The light entrance area 311 and the light exit area 312 are not provided with a reflective coating, so that light can enter the light deflecting element 30 from the light entrance area 311 and exit the light deflecting element 30 from the light exit area 312. The reflective area 313 is provided with a reflective coating so that light is reflected when passing through the reflective area 313.

[0216] In one example, the size of the light entrance area 311 is equal to the size of the light exit area 312, and the size of the reflection area 313 is no smaller than the size of the light entrance area 311 or the light exit area 312. This ensures that light entering the light deflection element 30 from the light entrance area 311 is reflected and then emitted from the light exit area 312 to the photosensitive component 40, thereby avoiding light loss and reducing the generation of stray light. In a specific example of the present application, the size of the light entrance area 311 is equal to the size of the reflection area 313, and the size of the light exit area 312 is equal to the size of the light exit area 312. This improves the multiple reflection effect of the light deflection element 30, avoids light loss, and reduces the generation of stray light.

[0217] Furthermore, both the light entrance area 311 and the light exit area 312 are located on the first surface 31. That is, the light entering and exiting the camera module 1 are located on the same side of the light deflection element 30. Thus, the optical lens 10 and the photosensitive component 40 are concentrated on the same side of the light deflection element 30. As a result, the height of the camera module 1 is determined solely by the sum of the height of the optical lens 10 or the photosensitive component 40 and the height of the light deflection element 30, which helps to reduce the height of the camera module 1.

[0218] In one embodiment of the present application, as shown in FIG2A , the light deflecting element 30 can reflect light within the light deflecting element 30 an odd number of times to guide the light from the optical lens 10 through the light deflecting element 30 to the photosensitive component 40. When the light is reflected three times within the light deflecting element 30, the light passes through the light entrance area 311 of the first surface 31 and enters the light deflecting element 30; at least some of the light that passes through the light entrance area 311 of the first surface 31 is reflected at the second surface 32; at least some of the light reflected from the second surface 32 is reflected at the reflection area 313 of the first surface 31; and at least some of the light reflected from the reflection area 313 of the first surface 31 is reflected at the fourth surface 34, so that the light passes through the light exit area 312 of the first surface 31 and reaches the photosensitive component 40.

[0219] In another embodiment of the present application, as shown in Figure 2B, when the light is reflected five times in the light deflecting element 30, the light passes through the light entrance area 311 of the first surface 31 and enters the light deflecting element 30; at least some of the light passing through the light entrance area 311 of the first surface 31 is reflected at the second surface 32; at least some of the light reflected from the second surface 32 is reflected at the reflection area 313 of the first surface 31; at least some of the light reflected from the reflection area 313 of the first surface 31 is reflected at the third surface 33; at least some of the light reflected from the third surface 33 is reflected at the light exit area 312 of the first surface 31; and, at least some of the light reflected from the light exit area 312 of the first surface 31 is reflected at the fourth surface 34, so that the light passes through the light exit area 312 of the first surface 31 and reaches the photosensitive component 40.

[0220] It should be understood that light from the optical lens 10 may pass through the light incident area 311 of the first surface 31, enter the light deflecting element 30, and undergo an odd number of reflections within the light deflecting element 30. At least some of the light may then reach the second surface 32 and be reflected there. At least some of the light reflected from the second surface 32 may then reach the reflection area 313 or the light incident area 311 of the first surface 31. When light reaches the reflection area 313 of the first surface 31, it is reflected at the reflection area 313 of the first surface 31, and at least some of the light reflected from the reflection area 313 of the first surface 31 can reach the third surface 33 or the fourth surface 34 and be reflected at the third surface 33 or the fourth surface 34; when light reaches the light entrance area 311 of the first surface 31, when the incident angle of the light is close to or greater than the critical angle of the light turning element 30, the light can be reflected at the light entrance area 311 of the first surface 31 under total internal reflection, and at least some of the light reflected from the light entrance area 311 of the first surface 31 can reach the third surface 33 or the fourth surface 34 and be reflected at the third surface 33 or the fourth surface 34.

[0221] If at least some of the light reflected from the first surface 31 reaches the fourth surface 34 and is finally reflected at the fourth surface 34, it leaves the light deflecting element 30 and reaches the photosensitive component 40. As shown in FIG2A , in this embodiment, the light is reflected three times in the light deflecting element 30, which can effectively increase the focal length between the optical lens 10 and the photosensitive component 40, that is, the optical TTL of the camera module 1 can be effectively increased, making the camera module 1 suitable for capturing objects at a long distance and providing high-quality images of the distant objects.

[0222] If at least some of the light reflected from the first surface 31 reaches the third surface 33, then at least some of the light reflected from the third surface 33 may reach the light exit area 312 of the first surface 31. When the incident angle of the light is close to or greater than the critical angle of the light deflection element 30, the light may be reflected at the light exit area 312 of the first surface 31 under total internal reflection. At least some of the light reflected from the light exit area 312 of the first surface 31 may reach the fourth surface 34 and finally be reflected at the fourth surface 34, leaving the light deflection element 30 to reach the photosensitive component 40. As shown in FIG2B , in this embodiment, the light is reflected five times in the light deflection element 30, which can effectively increase the focal length between the optical lens 10 and the photosensitive component 40. In other words, the optical TTL of the camera module 1 can be effectively increased, making the camera module 1 suitable for capturing objects at a long distance and providing high-quality images of the distant objects.

[0223] As shown in FIG2C , in another embodiment of the present application, the light deflecting element 30 is implemented as a parallelogram prism. The light deflecting element 30 includes four surfaces, for example, a first surface 31, a second surface 32, a third surface 33, and a fourth surface 34. The planes of the first surface 31 and the third surface 33 are parallel to each other, and the planes of the second surface 32 and the fourth surface 34 are parallel to each other. The four surfaces of the light deflecting element 30 have a reflective function. For example, the first surface 31, the second surface 32, the third surface 33, and the fourth surface 34 are reflective surfaces that can reflect light.

[0224] In this embodiment, light is reflected four times by the light deflecting element 30. The photosensitive component 40 and the optical lens 10 are disposed on opposite sides of the light deflecting element 30. Light passing through the optical lens 10 is reflected four times within the light deflecting element 30 before being emitted and reaching the photosensitive component 40. For example, the optical lens 10 is disposed on one side of the first surface 31, and the photosensitive component 40 is disposed on one side of the third surface 33.

[0225] Continuing with reference to FIG2C , the light deflecting element 30 can reflect light within the light deflecting element 30 an even number of times to guide the light from the optical lens 10 through the light deflecting element 30 to the photosensitive component 40. When the light is reflected four times within the light deflecting element 30, the light passes through the light entrance area 311 of the first surface 31 and enters the light deflecting element 30; at least some of the light that passes through the light entrance area 311 of the first surface 31 is reflected at the second surface 32; at least some of the light reflected from the second surface 32 is reflected at the reflection area 313 of the first surface 31; at least some of the light reflected from the reflection area 313 of the first surface 31 is reflected at the third surface 33; and at least some of the light reflected from the third surface 33 is reflected at the fourth surface 34, so that the light passes through the light exit area 312 of the first surface 31 and reaches the photosensitive component 40.

[0226] In one embodiment of the present application, the light deflection element 30 can be implemented as an integrated prism, as shown in Figures 2A, 2B and 2C, and the integrated prism is a trapezoidal prism. In another embodiment of the present application, the light deflection element 30 can also be implemented as a split prism 36, that is, the light deflection element 30 can be formed by combining multiple prisms. For example, the split prism 36 includes at least two prisms: a first prism 361 and a second prism 362, wherein, in a specific example of the present application, as shown in Figure 3A, the first prism 361 is a parallelogram prism, and the second prism 362 is a triangular prism. The first prism 361 and the second prism 362 are joined together by optically transparent adhesives or snaps to form the light deflection element 30. In this way, when the light deflection element 30 is manufactured by a paneling method, the manufacturing process can be simplified and the utilization rate of raw materials can be improved. Of course, it should be understood that in another specific example of the present application, the first prism 361 can be a right-angled trapezoidal prism, and the second prism 362 can be a right-angled triangular prism or a right-angled trapezoidal prism. The first prism 361 and the second prism 362 are joined together by optically transparent adhesive or snap fasteners to form a light turning element 30.

[0227] In another specific example of the present application, as shown in Figure 3B, the split prism 36 also includes a third prism 363, wherein the first prism 361 is a right-angled trapezoidal prism, the second prism 362 is a rectangular prism, and the third prism 363 is a right-angled trapezoidal prism. The first prism 361, the second prism 362 and the third prism 363 are joined together by optically transparent adhesives or snaps to form a light deflection element 30. In this way, when the light deflection element 30 is manufactured by paneling, the manufacturing process can be simplified and the utilization rate of raw materials can be improved. Alternatively, the first prism 361 and the third prism 363 are triangular prisms, and the second prism 362 is a quadrilateral prism. For example, the first prism 361 and the third prism 363 are right-angled triangular prisms, and the second prism 362 is a rectangular prism. Alternatively, the first prism 361 and the third prism 363 are triangular prisms, and the second prism 362 is a parallelogram prism. The first prism 361, the second prism 362 and the third prism 363 are joined together by optically transparent adhesives or snaps to form a light turning element 30.

[0228] Continuing with reference to Figure 3A, in the split prism 36, when light passes through the light entrance area 311 of the first prism 361 and enters the first prism 361, at least some of the light is reflected at least once in the first prism 361 and reaches the second prism 362, and then at least some of the light reaching the second prism 362 is reflected at least once in the second prism 362 and reaches the light exit area 312 of the second prism 362, and is emitted from the second prism 362 to reach the photosensitive component 40.

[0229] Continuing with reference to Figure 3B, in the split prism 36, the second prism 362 is arranged between the first prism 361 and the third prism 363. When light passes through the light entrance area 311 of the first prism 361 and enters the first prism 361, at least some of the light is reflected at least once in the first prism 361 and reaches the second prism 362. Then, at least some of the light reaching the second prism 362 is reflected at least once in the second prism 362 and reaches the third prism 363. Finally, at least some of the light reaching the third prism 363 is reflected at least once in the third prism 363 and reaches the light exit area 312 of the third prism 363, and is emitted from the third prism 363 to reach the photosensitive component 40.

[0230] It should be understood that in the present application, the light entrance area 311 of the first prism 361 and the light exit area 312 of the third prism 363 are both arranged on the same side of the light deflection element 30 (split prism 36) so that light can enter and exit from the same side of the light deflection element 30. In this way, the optical lens 10 and the photosensitive component 40 can be concentrated on the same side of the light deflection element 30 to reduce the height of the camera module 1.

[0231] Furthermore, the light deflection element 30 may also include a light-shielding film disposed between the first prism 361 and the second prism 362 and / or between the second prism 362 and the third prism 363. Specifically, as shown in FIG3A and FIG3B , a U-shaped light-shielding film is provided on the side of the second prism 362 facing the first prism 361, and a U-shaped light-shielding film is provided on the side of the second prism 362 facing the third prism 363. It is understandable that the light-shielding film may also be provided on the side of the first prism 361 or the third prism 363 facing the second prism 362. By providing the light-shielding film, the influence of stray light on imaging can be reduced, thereby alleviating the problem of glare.

[0232] It should be understood that the split prism 36 may also include other numbers of prisms, such as four prisms, five prisms, or six prisms, and this application is not limited thereto. Of course, in other embodiments of the application, the light deflecting element 30 may also be implemented as a plurality of reflectors, with the plurality of reflectors being disposed at locations where light needs to be reflected to form the light deflecting element 30.

[0233] In one embodiment of the present application, as shown in Figures 4 to 9C, the driving device 60 is implemented as a chip driving component, and the driving device 60 is configured to drive the photosensitive component 40 to move relative to the light deflecting element 30 to achieve optical focus and / or optical image stabilization. It is worth mentioning that in this embodiment, the position of the optical lens 10 or the light deflecting element 30 is not adjusted to maintain the relative position between the optical lens 10 and the light deflecting element 30 unchanged, thereby avoiding the change in the path of the light incident on the light deflecting element 30, which causes the reflection path of the light in the light deflecting element 30 and the light exit path to differ significantly from the predetermined path, thereby reducing the imaging quality of the camera module 1. That is, the driving device 60 is configured to drive the photosensitive component 40 to move relative to the light deflecting element 30 and the optical lens 10.

[0234] In one embodiment of the present application, the light deflecting element 30 is disposed in the fixed portion of the driving device 60, and the photosensitive component 40 is disposed in the movable portion of the driving device 60. Furthermore, the optical lens 10 is directly or indirectly fixed to the light deflecting element 30, and the filter assembly 50 is directly or indirectly fixed to the photosensitive component 40. The driving device 60 can drive the photosensitive component 40 to move relative to the light deflecting element 30, thereby changing the optical performance of the camera module 1 by moving the chip. In other words, the photosensitive component 40 can be moved relative to the light deflecting element 30 under the drive of the driving device 60 to achieve optical focus and / or optical image stabilization functions.

[0235] As mentioned above, when the light deflecting element 30 is implemented as a trapezoidal prism, it includes a top side on which the optical lens 10 and the photosensitive component 40 are disposed, a bottom side opposite the top side, and a peripheral side disposed between the top and bottom sides. The peripheral side includes a first side 71, a second side 72, a third side 73, and a fourth side 74 disposed in a clockwise direction, wherein the first side 71 and the third side 73 are opposite, and the second side 72 and the fourth side 74 are opposite. The optical lens 10 is disposed near the first side 71, and the photosensitive component 40 is disposed near the third side 73. The lateral dimension of the light deflecting element 30 on the top side is greater than its lateral dimension on the bottom side, that is, the lateral dimension of the light deflecting element 30 gradually decreases from the top side to the bottom side along the optical axis. This allows for a larger spatial space between the peripheral side and the bottom side of the light deflecting element 30 for accommodating the drive device 60. It should be understood that the top side, the bottom side, the first side 71 , the second side 72 , the third side 73 and the fourth side 74 may also be applicable to other components in the camera module 1 .

[0236] In a specific example of this application, the drive device 60 is positioned around the light deflecting element 30, with at least a portion of the drive device 60 lower than the top surface of the light deflecting element 30. This arrangement, on the one hand, provides ample space for the drive device 60, making the camera module 1 more compact. On the other hand, it reduces the height of the drive device 60, and thus the shoulder height of the camera module 1, providing sufficient space for the photosensitive component 40 and the filter component 50, thereby further reducing the height of the camera module 1. It should be understood that the shoulder height of the camera module 1 corresponds to the height of the drive device 60.

[0237] As shown in Figures 4 to 6, in one embodiment of the present application, the driving device 60 includes an upper cover 610a, a movable carrier 66a, a frame 63a, a fixed base 61a, a focus driving unit 62a, an anti-shake driving unit 65a and a connecting circuit board 44, wherein the upper cover 610a and the fixed base 61a form a accommodating cavity, and the movable carrier 66a, the frame 63a, the focus driving unit 62a, the anti-shake driving unit 65a and the connecting circuit board 44 are accommodated in the accommodating cavity. The movable carrier 66a is movably disposed on the frame 63a, which is movably disposed on the fixed base 61a. The anti-shake drive unit 65a is disposed between the movable carrier 66a and the frame 63a to drive the movable carrier 66a to move relative to the frame 63a along the X-axis and Y-axis directions. That is, the anti-shake drive unit 65a is configured to drive the movable carrier 66a to move relative to the frame 63a in a direction perpendicular to the optical axis of the camera module 1. The focus drive unit 62a is disposed between the frame 63a and the fixed base 61a to drive the frame 63a to move relative to the fixed base 61a along the Z-axis direction. That is, the focus drive unit 62a is configured to drive the frame 63a to move relative to the fixed base 61a in a direction parallel to the optical axis of the camera module 1. The connecting circuit board 44 is electrically connected to the focus drive unit 62a, the anti-shake drive unit 65a, and the chip circuit board 42 to achieve circuit conduction of the drive device 60.

[0238] Furthermore, the light deflection element 30 and the optical lens 10 are arranged on the fixed base 61a of the driving device 60, and the photosensitive component 40 is transmissively arranged on the frame 63a of the driving device 60, so that when the focusing driving part 62a drives the frame 63a to move relative to the fixed base 61a in a direction parallel to the optical axis, the photosensitive component 40 moves accordingly in a direction parallel to the optical axis.

[0239] In other words, the driving device 60 includes: a fixed base 61a to which the light deflecting element 30 is fixed; a frame 63a movably mounted on the fixed base 61a; a movable carrier 66a movably mounted on the frame 63a, on which the photosensitive element 40 is mounted; and an anti-shake drive unit 65a disposed between the movable carrier 66a and the frame 63a for driving the movable carrier 66a to move relative to the frame 63a. The anti-shake drive unit 65a is disposed around the light deflecting element 30, with at least a portion of the anti-shake drive unit 65a being lower than the top surface of the light deflecting element 30. This reduces the height of some components of the driving device 60, thereby reducing the shoulder height of the driving device 60 and thereby lowering the height of the camera module 1.

[0240] The upper cover 610a and the fixed base 61a interlock to form a housing cavity for components such as the movable carrier 66a, frame 63a, focus drive unit 62a, anti-shake drive unit 65a, and connecting circuit board 44. This prevents dust from entering and prevents components from falling when impacted. Furthermore, the upper cover 610a has a lens opening 6101a at the location corresponding to the optical lens 10. The optical lens 10 can pass through this lens opening 6101a and be fixed to the light deflecting element 30 to avoid affecting the incident light.

[0241] As shown in Figures 6, 7, and 9A, in one embodiment of the present application, the fixed base 61a includes a base body 611a and a supporting portion 613a disposed within the base body 611a. The supporting portion 613a is located in the middle of the base body 611a and extends in height from the base body 611a. The supporting portion 613a has a groove that gradually decreases in size from its top to its bottom along the optical axis. The light deflecting element 30 is fixed within the groove of the supporting portion 613a. The shape of the groove of the supporting portion 613a matches the shape of the light deflecting element 30. Furthermore, the height of the supporting portion 613a is not less than the height of the light deflecting element 30 to prevent the top surface of the light deflecting element 30 from protruding beyond the top surface of the supporting portion 613a, thereby preventing scratches or damage to the surface of the light deflecting element 30. For example, in one specific example of the present application, the top surface of the light deflecting element 30 is flush with the top surface of the supporting portion 613a.

[0242] It should be understood that due to the large size of the light deflection element 30, the carrier portion 613a occupies most of the space within the drive device 60. To provide a certain amount of space for other components of the drive device 60, the first side 71, bottom side, and upper cover 610a of the carrier portion 613a form a connecting belt accommodating cavity 614a to accommodate the connecting circuit board 44. The third side 73, bottom side, and upper cover 610a of the carrier portion 613a form a driving unit accommodating cavity 616a to accommodate the movable carrier 66a, frame 63a, focus driving unit 62a, and anti-shake driving unit 65a. The connecting belt accommodating cavity 614a and the driving unit accommodating cavity 616a are arranged relative to each other on the circumference of the carrier portion 613a. This prevents interference between the connecting circuit board 44 and other components in the drive device 60, which could affect the conductive effect, and also makes the structure of the camera module 1 more compact.

[0243] Furthermore, the fixed base 61a also includes a focus fixing portion 612a, which is disposed on the side of the fixed base 61a. That is, the fixed base 61a includes a base body 611a extending in the horizontal direction and a focus fixing portion 612a extending from the base body 611a in the height direction. In a specific example of the present application, the focus fixing portion 612a is disposed near the side where the photosensitive component 40 is located, that is, the focus fixing portion 612a is disposed near the third side 73 of the fixed base 61a. In order to make the space utilization within the drive device 60 higher, the focus fixing portion 612a is disposed on the second side 72 of the fixed base 61a, or on the fourth side 74 opposite the second side 72.

[0244] Continuing to refer to Figures 6, 7 and 9A, in one embodiment of the present application, the frame 63a is movably disposed on the fixed base 61a, the movable carrier 66a is movably disposed on the frame 63a, and the photosensitive component 40 is fixedly disposed on the movable carrier 66a, so that when the frame 63a is driven to move along the Z-axis direction relative to the fixed base 61a, the frame 63a can drive the movable carrier 66a and then drive the photosensitive component 40 to move along the Z-axis direction to realize the optical focusing function.

[0245] Furthermore, the frame 63a includes an anti-shake frame 633a and a focus frame 631a. The anti-shake frame 633a extends horizontally, while the focus frame 631a extends vertically integrally from the anti-shake frame 633a. In other words, the frame 63a includes the anti-shake frame 633a extending horizontally and the focus frame 631a extending vertically from the anti-shake frame 633a. When viewed from above, the anti-shake frame 633a and the focus frame 631a form a "П"-shaped structure with an opening facing the support portion 613a. The movable carrier 66a and the anti-shake frame 633a are arranged relative to each other in the height direction, and the focus frame 631a and the focus fixing part 612a of the fixed base 61a are arranged relative to each other in the horizontal direction. The anti-shake driving part 65a is arranged between the movable carrier 66a and the anti-shake frame 633a to drive the movable carrier 66a to move in the horizontal direction to realize the optical anti-shake function; the focus driving part 62a is arranged between the focus frame 631a and the focus fixing part 612a to drive the frame 63a and then drive the movable carrier 66a to move in the height direction to realize the optical focus function.

[0246] Furthermore, the anti-shake frame 633a includes a first arm 6331a extending along the length direction (or X-axis direction) and a second arm 6332a extending along the width direction (or Y-axis direction), with the first arm 6331a and the second arm 6332a being interconnected. Alternatively, the first arm 6331a of the anti-shake frame 633a is positioned on the second side 72 or the fourth side 74, the second arm 6332a of the anti-shake frame 633a is positioned on the third side 73, and the focus frame 631a is positioned on the side opposite the first arm 6331a of the anti-shake frame 633a and extending in the height direction. It should be understood that, in this application, the frame 63a is only positioned on three sides proximal to the photosensitive component 40, e.g., the second side 72, the third side 73, and the fourth side 74. The frame 63a is not positioned on the side facing the optical lens 10, e.g., the first side 71. This arrangement can reduce the single-sided size of the drive device 60, thereby reducing the lateral size of the camera module 1.

[0247] As shown in Figures 6 to 9A, in an embodiment of the present application, the focus drive unit 62a is arranged on the side of the drive device 60, and the focus drive unit 62a is arranged between the fixed base 61a and the frame 63a in the height direction to drive the frame 63a to move relative to the fixed base 61a along the Z-axis direction, that is, the focus drive unit 62a is configured to drive the frame 63a to move relative to the fixed base 61a in a direction parallel to the optical axis of the camera module 1 to achieve the optical focus function. For example, in a specific example of the present application, the focus drive unit 62a is arranged between the focus frame 631a of the frame 63a and the focus fixing portion 612a of the fixed base 61a. The focus drive unit 62a includes a focus magnet 621a and a focus coil 622a opposite thereto. The focus magnet 621a is disposed on one of the focus frame 631a and the focus fixing unit 612a, and the focus coil 622a is disposed on the other of the focus frame 631a and the focus fixing unit 612a. In a specific example of the present application, the focus magnet 621a and the focus coil 622a are disposed horizontally relative to each other on the circumference of the light deflection element 30; wherein the winding axis of the focus coil 622a is parallel to the optical axis direction of the camera module 1. It should be understood that in the present application, the focus coil 622a is wound around an axis in the height direction, and the axis is the winding axis of the focus coil 622a. In other words, the focus coil 622a is formed by winding a wire around the winding axis.

[0248] In one embodiment of the present application, the focus magnet 621a is disposed on the focus frame 631a, and the focus coil 622a is disposed on the focus fixing portion 612a. The focus magnet 621a and the focus coil 631a interact to drive the focus frame 631a to move relative to the focus fixing portion 612a in a direction parallel to the optical axis of the camera module 1. For example, in a specific example of the present application, the outer wall of the focus frame 631a has a magnet mounting groove, and the focus magnet 621a is disposed in the magnet mounting position to be fixed to the focus frame 631a. The focus fixing portion 612a includes a first support arm 6121a and a second support arm 6122a, which are spaced apart from each other. The first support arm 6121a and the second support arm 6122a extend integrally in the height direction from the base body 611a, with a space defined between the first support arm 6121a and the second support arm 6122a. The focus coil 622a is disposed in the space between the first support arm 6121a and the second support arm 6122a. Furthermore, coil mounting grooves are provided on the first support arm 6121a and the second support arm 6122a, respectively. The openings of the coil mounting grooves face the space between the first support arm 6121a and the second support arm 6122a. The focus coil 622a is disposed in the coil mounting grooves to be stably clamped between the first support arm 6121a and the second support arm 6122a.

[0249] As shown in Figures 7 to 9B, it should be understood that the focusing magnet 621a and the focusing coil 622a are arranged relative to each other in the horizontal direction, so that the frame 63a is driven to move relative to the fixed base 61a through the magnetic field force between the focusing coil 622a and the focusing magnet 621a. The greater the magnetic field force between the focusing coil 622a and the focusing magnet 621a, the greater the stroke that can drive the frame 63a to move along the optical axis. In the present application, the focus drive unit 62a also includes a magnetic conductive member 624a, which is arranged between the first support arm 6121a and the second support arm 6122a. The magnetic conductive member 624a extends in the height direction, and its top surface is not higher than the top surface of the first support arm 6121a and the second support arm 6122a. The focusing coil 622a is wound around the circumference of the magnetic member 624a along the height direction. The winding height of the focusing coil 622a does not exceed the height of the magnetic member 624a to prevent the focusing coil 622a from falling off the magnetic member 624a. This arrangement, on the one hand, disposes the magnetic member 624a inside the focusing coil 622a. When the focusing coil 622a is energized, the magnetic field of the magnetic member 624a is magnetized to generate a magnetic field. The magnetic field generated by the magnetic member 624a and the magnetic field generated by the focusing coil 622a are superimposed on each other, thereby increasing the overall magnetic field strength, increasing the magnetic field force between the focusing coil 622a and the focusing magnet 621a, and driving the frame 63a to produce a larger movement stroke. On the other hand, since the magnetic conductive part 624a extends in the height direction and has a certain height, the number of turns of the focusing coil 622a wound on the magnetic conductive part 624a increases, the magnetic field force between the focusing coil 622a and the focusing magnet 621a increases, and the driving frame 63a produces a larger moving stroke.

[0250] In one embodiment of the present application, the focus coil 622a and the focus magnet 621a extend in a height direction, with the height of the focus coil 622a being greater than the height of the focus magnet 621a. Specifically, the focus coil 622a is disposed on a sidewall of the focus fixing portion 612a, and the focus magnet 621a is disposed on a sidewall of the focus frame 631a. The height of the focus coil 622a is greater than the height of the focus magnet 621a, so that the focus magnet 621a can always interact with the focus magnet 622a during movement of the focus frame 631a.

[0251] Furthermore, in one embodiment of the present application, the height of the focus drive unit 62a is greater than the height of the photosensitive component 40, and the magnetic conductive member 624a of the focus drive unit 62a extends in the height direction to a position close to the upper cover 610a, and the top surface of the magnetic conductive member 624a is higher than the top surface of the photosensitive component 40. It should be understood that the photosensitive component 40 moves along the Z-axis direction under the drive of the focus drive unit 62a, and the photosensitive component 40 needs to have sufficient space in the height direction to meet its movement stroke. During the optical focusing process, the magnetic conductive member 624a and the focus coil 622a are stators, which have a higher height to provide a greater driving force. The top surface of the photosensitive component 40 is lower than the top surface of the magnetic conductive member 624a, and also meets the larger movement stroke requirement of the photosensitive component 40.

[0252] It should be understood that in the present application, the focus coil 622a is disposed around the magnetic member 624a, and the magnetic member 624a has a certain thickness to provide sufficient strength to support the focus coil 622a. However, because the magnetic member 624a and the focus magnet 621a are arranged horizontally relative to each other, the interaction between the magnetic member 624a and the focus magnet 621a generates a horizontal magnetic attraction force to movably retain the frame 63a within the fixed base 61a. When the magnetic attraction between the magnetic member 624a and the focus magnet 621a is too strong, that is, the magnetic attraction between the magnetic member 624a and the focus magnet 621a is greater than the magnetic thrust generated by the interaction between the focus magnet 621a and the focus coil 622a, the frame 63a cannot move under the influence of the magnetic thrust. To avoid this situation, in this application, the magnetic member 624a is hollow and has a through-hole in its center to reduce the magnetic attraction between the magnetic member 624a and the focusing magnet 621a. When the magnetic attraction between the magnetic member 624a and the focusing magnet 621a is less than the magnetic thrust generated by the interaction between the focusing magnet 621a and the focusing coil 622a, the frame 63a can move under the influence of this magnetic thrust. Of course, the size of the through-hole in the magnetic member 624a can be determined based on actual needs.

[0253] Among them, the focusing coil 622a can be implemented as being directly wound around the circumference of the magnetic conductive part 624a, or it can be implemented as being prefabricated and then placed on the circumference of the magnetic conductive part 624a; the magnetic conductive part 624a can be implemented as an iron core, or it can be implemented as other metal materials, and this application does not impose any restrictions on this.

[0254] In a specific example of the present application, the magnetic member 624a is disposed within the coil mounting slot, allowing the focus coil 622a to be stably positioned between the first support arm 6121a and the second support arm 6122a. Furthermore, the bottom of the magnetic member 624a is larger than the rest of the magnetic member 624a. For example, the magnetic member 624a has a "⊥"-shaped structure. This prevents the focus coil 622a from falling off and allows it to be more securely positioned between the first support arm 6121a and the second support arm 6122a.

[0255] As shown in Figure 8B, in another embodiment of the present application, the magnetic conductive member 624a is arranged on the side of the focusing coil 622a away from the focusing magnet 621a, and the magnetic conductive member 624a and the focusing magnet 621a are arranged opposite to each other in the horizontal direction. Furthermore, the magnetic conductive member 624a extends in the height direction and is arranged between the positioning piece 615a and the base body 611a, that is, the two ends of the magnetic conductive member 624a are respectively fixed by the positioning piece 615a and the base body 611a. When the magnetic conductive member 624a interacts with the focusing magnet 621a to generate a magnetic attraction force in the horizontal direction, under the action of the magnetic attraction force, the frame 63a is movably retained in the fixed base 61a. In this embodiment, the magnetic conductive member 624a can be implemented as a metal sheet, such as an iron sheet.

[0256] It should be understood that the focusing coil 622a can also be implemented as a planar runway coil, and the plane where the focusing coil 622a is located is parallel to the plane where the magnetic member 624a is located, so that when the magnetic member 624a is set, there will be no interference between the focusing coil 622a.

[0257] Continuing to refer to Figures 6 and 9A, in an embodiment of the present application, the drive device 60 also includes a focus guide portion 64a, which is clamped between the frame 63a and the fixed base 61a, and the extension direction of the focus guide portion 64a is parallel to the optical axis of the camera module 1. When the focus drive portion 62a drives the frame 63a to move along the Z-axis direction, the focus guide portion 64a always supports the frame 63a, so that the frame 63a can move smoothly relative to the fixed base 61a, thereby improving the stability of the movement of the drive device 60 during the optical focusing process, thereby improving the imaging quality. In a specific example of the present application, the focus guide portion 64a is arranged on the same side as the focus drive portion 62a, and the focus guide portion 64a is arranged between the focus frame 631a of the frame 63a and the focus fixing portion 612a of the fixed base 61a. Furthermore, the focus guide portion 64a includes a top surface, a bottom surface opposite to the top surface, and an outer peripheral wall connected between the top surface and the bottom surface. The outer peripheral wall of the focus guide portion 64a abuts against the focus fixing portion 612a and the focus frame 631a respectively.

[0258] In one embodiment of the present application, a first guide rail 6123a is provided on the side of the focus fixing portion 612a facing the focus frame 631a, and a second guide rail 632a is provided on the side of the focus frame 631a facing the focus fixing portion 612a. The first guide rail 6123a and the second guide rail 632a are arranged opposite each other to clamp the focus guide portion 64a therebetween. The first guide rail 6123a is longer in height than the second guide rail 632a, and the focus guide portion 64a is longer in height than the second guide rail 632a, to prevent the frame 63a from disengaging from the focus guide portion 64a during movement.

[0259] In one embodiment of the present application, the focus guide portion 64a may be implemented as a guide rod 641a, or the focus guide portion 64a may also be implemented as a ball.

[0260] Furthermore, in one embodiment of the present application, the first support arm 6121a and the second support arm 6122a have two first guide rails 6123a, and the focus frame 631a has two second guide rails 632a. The two first guide rails 6123a and the second guide rails 632a are arranged opposite each other. In other words, there are two first guide rails 6123a, which are arranged parallel to each other and are respectively provided on the first support arm 6121a and the second support arm 6122a. Correspondingly, there are two second guide rails 632a, which are arranged parallel to each other and are respectively provided on either side of the magnet mounting area. The two second guide rails 632a and the two first guide rails 6123a are arranged opposite each other. The focus guide 64a includes two guide rods 641a, which are clamped between the two first guide rails 6123a and the two second guide rails 632a.

[0261] In the present application, the shape of the first guide rail 6123a and the second guide rail 632a can be a planar structure, a "∟"-shaped structure, a "["-shaped structure, or a "<"-shaped structure, that is, the focus guide portion 64a has one, two, or three contact points with the first guide rail 6123a or the second guide rod 641a, so that the focus guide portion 64a can be firmly clamped between the first guide rail 6123a and the second guide rail 632a. In a specific example of the present application, the two first guide rails 6123a are in a "∟"-shaped structure to facilitate their molding on the first support arm 6121a and the second support arm 6122a; the two second guide rails 632a are in a "["-shaped structure or a "<"-shaped structure. Of course, the two second guide rails 632a can also be in a "["-shaped and "<"-shaped structures, respectively.

[0262] As shown in Figures 6 to 9A, it should be understood that although the extension direction of the focus guide 64a is parallel to the optical axis, the focus guide 64a may still tilt during the movement of the frame 63a, thereby affecting the driving effect. In the present application, the fixed base 61a further includes a positioning piece 615a, which is fixed to the fixed base 61a, and the bottom surface of the positioning piece 65a abuts the top surface of the focus guide 64a. In other words, one end of the focus guide 64a is fixed to the base body 611a, and the other end of the focus guide 64a is fixed to the positioning piece 615a.

[0263] The plane where the positioning piece 615a is located is parallel to the plane where the base body 611a is located. The bottom surface of the focus guide part 64a is fixed to the base body 611a, and the top surface of the focus guide part 64a abuts against the positioning piece 615a to keep the focus guide part 64a parallel to the optical axis of the camera module 1.

[0264] Furthermore, although the two guide rods 641a are arranged relatively parallel, they may still tilt and interfere with each other during the movement of the frame 63a. When the two guide rods 641a are clamped between the positioning piece 615a and the base body 611a, the positioning piece 615a maintains the two guide rods 641a in parallel during the movement of the frame 63a for optical focusing. This ensures parallelism between the two guide rods 641a.

[0265] Furthermore, the top ends of the first support arm 6121a and the second support arm 6122a of the focus fixing portion 612a are provided with positioning bosses 6124a, and the positioning piece 615a has corresponding positioning holes 6151a. The positioning bosses 6124a are disposed within the positioning holes 6151a, so that the positioning piece 615a is positioned at the top ends of the first support arm 6121a and the second support arm 6122a. There is no gap between the focus guide portion 64a and the positioning piece 615a, so that the focus guide portion 64a can be stably disposed between the positioning piece 615a and the base body 611a of the fixed base 61a. For example, in a specific example of the present application, the height length of the focus guide portion 64a is equal to the height of the first support arm 6121a and the second support arm 6122a, so that the top surface of the focus guide portion 64a and the bottom surface of the positioning piece 615a are in contact with each other.

[0266] It should be understood that the positioning piece 615a horizontally covers at least a portion of the top surface of the focus guide 64a, thereby supporting and securing the focus guide 64a. Of course, the positioning piece 615a can also horizontally cover the entire top surface of the focus guide 64a, and this application is not limited to this. In other words, the positioning piece 615a horizontally covers at least a portion of the top surface of the two guide rods 641a to maintain the two guide rods 641a in parallel.

[0267] As mentioned above, the magnetic conductive part 624a and the focusing magnet 621a are arranged opposite to each other in the horizontal direction. The interaction between the magnetic conductive part 624a and the focusing magnet 621a generates a magnetic attraction force in the horizontal direction. The action of the magnetic attraction force causes the focusing guide part 64a to be clamped between the focusing frame 631a and the focusing fixing part 612a. In the process of realizing the optical focusing function, the focusing guide part 64a always provides support for the focusing frame 631a. Furthermore, the magnetic conductive part 624a and the focusing magnet 621a are arranged relative to each other in the horizontal direction, so that a magnetic attraction force is generated in the horizontal direction between the magnetic conductive part 624a and the focusing magnet 621a. Under the action of the magnetic attraction force, frictional contact is always maintained between the focusing frame 631a and the focusing guide part 64a, and between the focusing guide part 64a and the focusing fixing part 612a, so as to maintain the stability of the frame 63a and effectively prevent the frame 63a from falling off as the camera module 1 shakes or inverts.

[0268] As shown in Figures 6, 7, 9A, and 9B, in one embodiment of the present application, a movable carrier 66a is movably mounted on a frame 63a, a photosensitive assembly 40 is fixedly mounted on the movable carrier 66a, and an anti-shake drive unit 65a is disposed between the movable carrier 66a and the frame 63a to drive the movable carrier 66a and, in turn, the photosensitive assembly 40 to move relative to the frame 63a along the X-axis and Y-axis directions to achieve optical image stabilization. In a specific example of the present application, the movable carrier 66a is mounted on an anti-shake frame 633a of the frame 63a, i.e., the movable carrier 66a, the anti-shake frame 633a, and the fixed base 61a are sequentially disposed in the height direction.

[0269] It should be understood that the movable carrier 66a is disposed above the anti-shake frame 633a, which is disposed above the base body 611a. At least a portion of the movable carrier 66a is lower than the top surface of the light deflection element 30, meaning that the movable carrier 66a is located at the highest position among the three components. In the present application, at least a portion of the movable carrier 66a is lower than the top surface of the light deflection element 30. Since the anti-shake frame 633a and the fixed base 61a are both located below the movable carrier 66a, the anti-shake frame 633a and the fixed base 61a are also lower than the top surface of the light deflection element 30. This reduces the height of some components in the drive device 60, thereby reducing the shoulder height of the drive device 60 and achieving the goal of lowering the height of the camera module 1.

[0270] In the present application, the movable carrier 66a is disposed between the frame 63a and the photosensitive assembly 40. The photosensitive assembly 40 is fixedly disposed on the movable carrier 66a and movably connected to the frame 63a. Thus, when the movable carrier 66a is driven by the anti-shake drive unit 65a, the photosensitive assembly 40 moves with the movable carrier 66a. In a specific example of the present application, the photosensitive assembly 40 is supported on the movable carrier 66a by the filter element holder 52 of the filter assembly 50. Specifically, the filter element holder 52 is disposed between the chip circuit board 42 and the movable carrier 66a. One end of the filter element holder 52 is fixed to the chip circuit board 42, and the other end is fixed to the movable carrier 66a.

[0271] In one embodiment of the present application, the movable carrier 66a is L-shaped, that is, the movable carrier 66a includes a third arm 662a extending along the length direction (or X-axis direction) and a fourth arm 663a extending along the width direction (or Y-axis direction), and the third arm 662a and the fourth arm 663a are connected to each other. Furthermore, the third arm 662a of the movable carrier 66a is arranged opposite to the first arm 6331a of the anti-shake frame 633a in the height direction, and the fourth arm 663a of the movable carrier 66a is arranged opposite to the second arm 6332a of the anti-shake frame 633a in the height direction, so that the anti-shake drive unit 65a is disposed between the movable carrier 66a and the anti-shake frame 633a. In other words, the movable carrier 66a is only disposed on two sides close to the photosensitive assembly 40, for example, the second side 72 and the third side 73, or the fourth side 74 and the third side 73.

[0272] The movable carrier 66a includes two openings, one of which faces the side where the focus drive unit 62a is located, and the other faces the side where the optical lens 10 is located. For example, when the focus drive unit 62a is located on the second side 72 of the drive device 60, one opening of the movable carrier 66a faces the second side 72, and the other faces the first side 71. The third arm 662a of the movable carrier 66a is located on the fourth side 74, and the fourth arm 663a of the movable carrier 66a is located on the third side 73. This arrangement fully utilizes the space within the camera module 1. The movable carrier 66a is not located on the side facing the focus drive unit 62a or the side facing the light deflecting element 30, thereby avoiding increasing the horizontal size of the camera module 1.

[0273] In one embodiment of the present application, the anti-shake drive unit 65a is horizontally disposed between the movable carrier 66a and the frame 63a to drive the movable carrier 66a, thereby driving the photosensitive assembly 40 to move relative to the frame 63a along the X-axis and Y-axis directions. It should be understood that the anti-shake drive unit 65a extends downward from the movable carrier 66a to the periphery of the light deflection element 30, with at least a portion of the anti-shake drive unit 65a below the top surface of the light deflection element 30. This arrangement reduces the height of the anti-shake drive unit 65a, thereby lowering the shoulder height of the drive device 60 and ultimately reducing the height of the camera module 1. The anti-shake drive unit 65a includes at least one anti-shake magnet 651a and at least one anti-shake coil 652a. The at least one anti-shake magnet 651a is mounted on one of the movable carrier 66a and the frame 63a, while the at least one anti-shake coil 652a is mounted on the other of the movable carrier 66a and the frame 63a. The at least one anti-shake magnet 651a and the at least one anti-shake coil 652a are arranged relative to each other in the height direction. In a specific example of the present application, the at least one anti-shake coil 652a is mounted on the movable carrier 66a, and the at least one anti-shake magnet 651a is mounted on the anti-shake frame 633a.

[0274] Furthermore, the top surface of the at least one anti-shake magnet 651a lies in a plane lower than the top surface of the light deflection element 30, and the bottom surface of the at least one anti-shake coil 652a lies in a plane lower than the top surface of the light deflection element 30. That is, in the present application, the at least one anti-shake magnet 651a and the at least one anti-shake coil 652a are disposed on the circumference of the light deflection element 30. The placement of the at least one anti-shake magnet 651a and the at least one anti-shake coil 652a can be further lowered, thereby reducing the shoulder height of the drive device 60 and achieving the purpose of reducing the height of the camera module 1.

[0275] In this application, the anti-shake drive unit 65a is arranged horizontally, and the focus drive unit 62a is arranged vertically. The plane where the anti-shake drive unit 65a is located is perpendicular or approximately perpendicular to the plane where the focus drive unit 62a is located. The focus drive unit 62a drives the frame 63a, the anti-shake drive unit 65a, and the movable carrier 66a to move in the vertical direction to achieve optical focus; the anti-shake drive unit 65a drives the movable carrier 66a to move in the horizontal direction to achieve optical image stabilization.

[0276] As shown in Figures 6, 7, and 9A, the at least one anti-shake magnet 651a includes a first anti-shake magnet 6511a and a second anti-shake magnet 6512a, and the at least one anti-shake coil 652a includes a first anti-shake coil 6521a and a second anti-shake coil 6522a. The length of the first anti-shake magnet 6511a is along the X-axis, and the length of the second anti-shake magnet 6512a is along the Y-axis. That is, the first anti-shake magnet 6511a and the second anti-shake magnet 6512a are arranged perpendicularly or approximately perpendicularly. The length of the first anti-shake coil 6521a is the same as the length of the camera module 1, for example, the X-axis, and the length of the second anti-shake coil 6522a is the same as the width of the camera module 1, for example, the Y-axis. That is, the first anti-shake coil 6521a and the second anti-shake coil 6522a are arranged perpendicularly or approximately perpendicularly.

[0277] Specifically, in one embodiment of the present application, the first anti-shake magnet 6511a is arranged on the first arm 6331a of the anti-shake frame 633a, the second anti-shake magnet 6512a is arranged on the second arm 6332a of the anti-shake frame 633a, the first anti-shake coil 6521a is arranged on the third arm 662a of the movable carrier 66a, and the second anti-shake coil 6522a is arranged on the fourth arm 663a of the movable carrier 66a. The first anti-shake magnet 6511a and the first anti-shake coil 6521a are arranged relative to each other in the height direction, and the second anti-shake magnet 6512a and the second anti-shake coil 6522a are arranged relative to each other in the height direction, so that the first anti-shake magnet 6511a and the first anti-shake coil 6521a interact with each other, and the second anti-shake magnet 6512a and the second anti-shake coil 6522a interact with each other, generating a magnetic field force to drive the movable carrier 66a to move along the X-axis and Y-axis directions.

[0278] It should be understood that in the present application, the number of first anti-shake coils 6521a can be two, the length direction of the two first anti-shake coils 6521a being the same as the length direction of the camera module 1, and the two first anti-shake coils 6521a being arranged side by side along the length direction of the camera module 1. The two first anti-shake coils 6521a are arranged opposite the first anti-shake magnet 6511a in the height direction to increase the magnetic field force between them. Of course, the number of second anti-shake coils 6522a can also be two, the length direction of the two second anti-shake coils 6522a being the same as the width direction of the camera module 1, and the two second anti-shake coils 6522a being arranged side by side along the width direction of the camera module 1. The number of first anti-shake coils 6521a and second anti-shake coils 6522a can also be three, four, etc., and this application does not impose any restrictions on this.

[0279] The drive device 60 further includes an anti-shake support portion 67a, which is disposed between the movable carrier 66a and the frame 63a. When the anti-shake drive portion 65a drives the movable carrier 66a to move along the X-axis and Y-axis directions, the anti-shake support portion 67a continuously supports the movable carrier 66a, allowing the movable carrier 66a to move smoothly relative to the frame 63a. This improves the stability of the drive device 60 during optical image stabilization, thereby enhancing image quality.

[0280] The anti-shake frame 633a of the frame 63a is provided with a first ball rolling groove 634a on its top surface, and the movable carrier 66a is provided with a second ball rolling groove 661a on its bottom surface. The first ball rolling groove 634a and the second ball rolling groove 661a are arranged opposite each other in the height direction, and the anti-shake support portion 67a is clamped in the first ball rolling groove 634a and the second ball rolling groove 661a. The diameters of the first ball rolling groove 634a and the second ball rolling groove 661a are both larger than the diameter of the anti-shake support portion 67a, so that the anti-shake support portion 67a can roll horizontally within the space formed by the first ball rolling groove 634a and the second ball rolling groove 661a.

[0281] Furthermore, there are three first ball rolling grooves 634a, located at the ends of the first arm 6331a, the ends of the second arm 6332a, and the junction between the first and second arms 6331a and 6332a of the anti-shake frame 633a. Three second ball rolling grooves 661a are located at the ends of the third arm 662a, the ends of the fourth arm 663a, and the junction between the third and fourth arms 662a and 663a of the movable carrier 66a. Correspondingly, there are three anti-shake support portions 67a, located within the three first ball rolling grooves 634a and the three second ball rolling grooves 661a, respectively, to provide more stable support for the movable carrier 66a. In one embodiment of the present application, the anti-shake support portion 67a can be implemented as a ball 671a or a slider. It should be understood that the number of anti-shake support portions 67a is at least three, but may also be four, five, or other numbers.

[0282] Furthermore, in one embodiment of the present application, the drive device 60 also includes an anti-shake magnetic sheet (not shown in the drawings). The anti-shake magnetic sheet is disposed on the movable carrier 66a and is arranged in a height-direction opposite to the anti-shake magnet 651a. The interaction between the anti-shake magnetic sheet and the anti-shake magnet 651a generates a magnetic attraction. This magnetic attraction clamps the anti-shake support portion 67a between the movable carrier 66a and the frame 63a. During the process of achieving optical image stabilization, the anti-shake support portion 67a always provides support for the movable carrier 66a. The anti-shake magnetic sheet and at least one anti-shake magnet 651a are arranged vertically opposite each other, generating a vertical magnetic attraction between the sheet and the anti-shake magnet 651a. This magnetic attraction maintains frictional contact between the movable carrier 66a and the anti-shake support portion 67a, as well as between the frame 63a and the anti-shake support portion 67a. This magnetic attraction clamps the anti-shake support portion 67a between the movable carrier 66a and the anti-shake frame 633a, maintaining the stability of the movable carrier 66a. The anti-shake magnetic element is made of a material that is attractive to magnets, such as iron.

[0283] It should be understood that the anti-shake magnetic sheet is arranged on the side of the anti-shake coil 652a away from the anti-shake magnet 651a. For example, the anti-shake magnetic sheet is fixed between the anti-shake coil 652a and the movable carrier 66a by gluing or welding, or the anti-shake magnetic sheet is arranged inside the movable carrier 66a by insert injection molding. This application does not impose any restrictions on this.

[0284] In one embodiment of the present application, the drive device 60 further includes a frame cover 630a, which engages with the anti-shake frame 633a of the frame 63a to accommodate components such as the anti-shake drive unit 65a, the movable carrier 66a, the anti-shake support unit 67a, and the anti-shake magnetic sheet between the frame cover 630a and the anti-shake frame 633a of the frame 63a. This prevents components from falling off during optical image stabilization, which could affect the anti-shake effect. Furthermore, the frame cover 630a corresponds to the structure of the anti-shake frame 633a, forming an "L"-shaped structure to engage with the first arm 6331a and the second arm 6332a of the anti-shake frame 633a.

[0285] In one embodiment of the present application, the drive device 60 further includes an anti-shake position sensing component 68a and a focus position sensing component 69a. The anti-shake position sensing component 68a includes an anti-shake position sensing element 681a. The anti-shake position sensing element 681a is disposed on the movable carrier 66a, opposite the anti-shake magnet 651a. When the movable carrier 66a moves, the relative position of the anti-shake position sensing element 681a and the anti-shake magnet 651a changes. Based on the strength of the magnetic field of the anti-shake magnet 651a sensed by the anti-shake position sensing element 681a, the position of the movable carrier 66a can be determined, and the current of the anti-shake coil 652a can be adjusted to move the movable carrier 66a to the desired position. In a specific example of the present application, the anti-shake position sensing element 681a is disposed within the anti-shake coil 652a to avoid increasing the size of the movable carrier 66a. The anti-shake position sensing element 681a can be implemented as a TMR, a Hall effect element, or a driver IC.

[0286] The focus position sensing assembly 69a includes a focus position sensing element 692a and a focus position sensing magnet 691a, wherein the focus position sensing element 692a is disposed on the focus fixing portion 612a of the fixed base 61a, and the focus position sensing magnet 691a is disposed on the focus frame 631a of the frame 63a. The focus position sensing element 692a and the focus position sensing magnet 691a are arranged horizontally relative to each other. When the frame 63a moves, the relative position of the focus position sensing element 692a and the focus position sensing magnet 691a changes. Based on the strength of the magnetic field of the focus position sensing magnet 691a sensed by the focus position sensing element 692a, the position of the frame 63a can be determined, and the current of the focus coil 622a can be adjusted to move the frame 63a to the desired position. In a specific example of the present application, the focus position sensing magnet 691a is a magnetic grating structure to meet the larger movement range requirements of the frame 63a. The focus position sensing element 692a may be implemented as a TMR, a Hall element, a driver IC, or the like.

[0287] As can be seen from the above embodiment, the focus drive unit 62a, anti-shake drive unit 65a, movable carrier 66a, frame 63a, and other components of the drive device 60 are collectively disposed within the drive unit accommodating cavity 616a. In other words, the focus drive unit 62a, anti-shake drive unit 65a, movable carrier 66a, frame 63a, and other components of the drive device 60 are concentrated on one side along the length of the light deflection element 30, thereby fully utilizing the internal space of the camera module 1.

[0288] In one embodiment of the present application, the camera module 1 further includes a focus electrical connection portion (not shown) and an anti-shake electrical connection portion (not shown), wherein the focus electrical connection portion and the anti-shake electrical connection portion are respectively electrically connected to the connection circuit board 44. In a specific example of the present application, the focus electrical connection portion can be integrally formed on the fixed base 61a using an insert injection molding process to electrically connect the focus coil 622a and the connection circuit board 44 to achieve circuit conduction of the focus drive portion 62a. In another specific example of the present application, the focus electrical connection portion can be implemented as a PIN pin to electrically connect the focus coil 622a and the connection circuit board 44.

[0289] In one specific example of the present application, the anti-shake electrical connection portion can be integrally formed on the movable carrier 66a using an insert molding process to electrically connect the anti-shake coil 652a and the connecting circuit board 44, thereby achieving circuit conductivity of the anti-shake drive unit 65a. In another specific example of the present application, the anti-shake electrical connection portion can be implemented as a PIN pin to electrically connect the anti-shake coil 652a and the connecting circuit board 44.

[0290] Furthermore, the photosensitive component 40 also includes a connecting circuit board 44, which is fixed and electrically connected to the chip circuit board 42 to provide electrical conduction between the chip circuit board 42 and external electronic devices. The applicant has found that when the photosensitive component 40 is driven by the driving device 60 to achieve movement, the connecting circuit board 44 becomes one of the sources of resistance to the movement of the photosensitive component 40. Therefore, in this application, the applicant further improves the connecting circuit board 44 of the photosensitive component 40 to reduce the resistance encountered by the photosensitive component 40 when being driven to achieve chip anti-shake or chip focus.

[0291] 6 and 9C , the connection circuit board 44 includes a first connection strip 45a, which includes a first connection portion 451a, a first side connection portion 452a, a first bend portion 453a, and a first lead portion 454a, which are sequentially connected. The first connection portion 451a connects the chip circuit board 42 and the first side connection portion 452a, and the first bend portion 453a connects the first side connection portion 452a and the first lead portion 454a. It should be understood that the first connection portion 451a, the first side connection portion 452a, the first bend portion 453a, and the first lead portion 454a are electrically connected. The first connection strip 45a is connected to the chip circuit board 42 via the first connection portion 451a and is electrically connected thereto. Thus, the chip circuit board 42 can be electrically connected to an external device or equipment via the first lead portion 454a of the first connection strip 45a. It is worth mentioning that in the present application, the first connecting strip 45 a can be a flexible circuit board or a hard-soft board, so that the first connecting strip 45 a can be bent to adapt to the space inside the camera module 1 .

[0292] Specifically, the first connection portion 451a extends laterally from the chip circuit board 42 in a direction away from the chip circuit board 42. One end of the first connection portion 451a is connected to the chip circuit board 42, and the other end of the first connection portion 451a is bent downward and connected to one end of the first side connection portion 452a. The first side connection portion 452a extends and bends around the circumference of the light deflection element 30 and the optical lens 10, so that the first side connection portion 452a is bent from the long side of the camera module 1 to the short side of the camera module 1, and the other end of the first side connection portion 452a is connected to one end of the first bending portion 453a. One end of the first bending portion 453a is connected to the bottom of the other end of the first side connection portion 452a, and the other end of the first bending portion 453a is connected to the first lead-out portion 454a. The first bending portion 453a is bent and arranged below the first side connection portion 452a. In one specific example, the first bent portion 453a is horizontally bent and disposed below the first side connecting portion 452a. It should be understood that, as shown in the drawings herein, the direction of the optical lens 10 relative to the light deflecting element 30 is considered "up," and the opposite direction is considered "down." In other words, the light deflecting element 30 is below the optical lens 10.

[0293] It should be understood that the provision of the first side connection portion 452a reduces the resistance of the photosensitive component 40 from the connection circuit board 44 when it moves in the horizontal direction, and the provision of the first bent portion 453a reduces the resistance of the photosensitive component 40 from the connection circuit board 44 when it moves in the height direction. In particular, in the present application, the driving device 60 can drive the photosensitive component 40 to move in the height direction to a distance of at least 2 mm, and the first bent portion 453a can be extended and retracted in the height direction to meet the requirements of the photosensitive component 40 moving in the height direction. Furthermore, the first bent portion 453a can be bent multiple times to allow the first bent portion 453a to have a longer extension and retraction distance in the height direction.

[0294] It is worth mentioning that in order to design the size of the camera module 1 to be smaller, in the present application, the fixed base 61a also includes a connecting belt accommodating cavity 614a formed between the base body 611a and the supporting portion 613a. The connecting belt accommodating cavity 614a is arranged on the side of the fixed base 61a close to the optical lens 10. The connecting belt accommodating cavity 614a is located below the optical lens 10 and the light turning element 30. The first bending portion 453a is accommodated in the connecting belt accommodating cavity 614a, thereby avoiding an increase in the length of the camera module 1. The first connecting strip 45a extends from the chip circuit board 42 toward the side closest to the optical lens 10 (i.e., away from the focus drive unit 62a and the anti-shake drive unit 65a). Portions of the first connecting strip 45a are bent below the optical lens 10 and the light deflecting element 30, allowing them to be positioned within the connecting strip receiving cavity 614a of the fixed base 61a. This optimizes the spatial configuration within the camera module 1 and reduces the size of the camera module 1. It is worth noting that "below" the light deflecting element 30 refers to below the top surface of the light deflecting element 30, that is, below the first surface 31 of the light deflecting element 30. Furthermore, "below" the light deflecting element 30 further refers to below the second surface 32 of the light deflecting element 30. Portions of the first connecting strip 45a are bent below an inclined surface (the second surface 32) of the light deflecting element 30, and the connecting strip receiving cavity 614a is located below an inclined surface (the second surface 32) of the light deflecting element 30.

[0295] It is worth mentioning that the first lead-out portion 454a of the first connecting belt 45a can be fixed to the fixed base 61a or the upper cover 610a, so that the first bent portion 453a, the first side connecting portion 452a, and the first connecting portion 451a located inside the camera module 1 are not affected by external factors, which further increases the resistance of the driving device 60 from the photosensitive component 40. For example, when the first lead-out portion 454a is not fixed, the movement of other devices or equipment connected to the camera module 1 may cause the first lead-out portion 454a to move, and the first bent portion 453a connected to the first lead-out portion 454a may also move. Ultimately, the resistance generated by the photosensitive component 40 increases.

[0296] Furthermore, in some embodiments, due to the improved specifications and increased functions of the photosensitive component 40, setting the first connecting band 45a only on one side will make the width of the first connecting band 45a too large. Therefore, the connecting circuit board 44 also includes a second connecting band 46a, and the second connecting band 46a is arranged on both sides of the chip circuit board 42 opposite to the first connecting band 45a.

[0297] In a specific example, the second connecting strip 46a includes a second connecting portion 461a, a second side connecting portion 462a, a second bent portion 463a, and a second lead portion 464a, which are sequentially connected. The second connecting portion 461a connects the chip circuit board 42 and the second side connecting portion 462a, and the second bent portion 463a connects the second side connecting portion 462a and the second lead portion 464a. It should be understood that the second connecting portion 461a, the second side connecting portion 462a, the second bent portion 463a, and the second lead portion 464a are electrically connected. The second connecting strip 46a is connected to the chip circuit board 42 via the second connecting portion 461a and is electrically connected. Therefore, the chip circuit board 42 can also be electrically connected to an external device or equipment via the second lead portion 464a of the second connecting strip 46a on the side opposite to the first connecting strip 45a. It is worth mentioning that in the present application, the second connecting belt 46 a can also be a flexible circuit board or a soft-hard combination board, so that the second connecting belt 46 a can be bent to adapt to the space inside the camera module 1.

[0298] In this example, the first connecting band 45a and the second connecting band 46a are arranged around the circumference of the optical lens 10 and the light deflection element 30, making full use of the fact that most of the components of the driving device 60 are arranged on the other side away from the optical lens 10. The camera module 1 has more space that can be utilized on the side where the optical lens 10 is arranged, thereby optimizing the space configuration.

[0299] Specifically, the second connecting portion 461a extends laterally from the chip circuit board 42 in a direction away from the chip circuit board 42. One end of the second connecting portion 461a is connected to the chip circuit board 42, and the other end of the second connecting portion 461a is bent downward and connected to one end of the second side connecting portion 462a. The second side connecting portion 462a extends and bends around the circumference of the light deflection element 30 and the optical lens 10, so that the second side connecting portion 462a bends from the long side of the camera module 1 to the short side of the camera module 1. The other end of the second side connecting portion 462a is connected to one end of the second bending portion 463a. One end of the second bending portion 463a is connected to the bottom of the other end of the second side connecting portion 462a, and the other end of the second bending portion 463a is connected to the second lead-out portion 464a. The second bending portion 463a is bent and arranged below the second side connecting portion 462a. In a specific example, the second bending portion 463a is bent in a horizontal direction. The second bending portion 463a is disposed below the second side connecting portion 462a in a horizontally bent form.

[0300] It should be understood that the provision of the second connecting strip 46a reduces the width of the first connecting portion 451a of the first connecting strip 45a, thereby reducing the resistance experienced by the photosensitive assembly 40 during movement. Furthermore, the simultaneous provision of the first connecting strip 45a and the second connecting strip 46a on both sides of the chip circuit board 42 further disperses the distribution of resistance. In one specific example, the second connecting strip 46a is symmetrically positioned with the first connecting strip 45a, further balancing the resistance exerted by the connection circuit board 44 on the drive device 60.

[0301] Correspondingly, in the present application, the second bending portion 463a can also be extended and retracted in the height direction to meet the requirement of the photosensitive component 40 moving in the height direction. The second bending portion 463a can also be bent multiple times so that the second bending portion 463a can have a longer extension and retraction stroke in the height direction.

[0302] It is worth mentioning that in one example, the second bending portion 463a is also accommodated in the connecting band accommodating cavity 614a of the fixed base 61a to reduce the increase in the length of the camera module 1, and the second connecting band 46a extends from the chip circuit board 42 to the side close to the optical lens 10 (that is, to the side away from the focus drive unit 62a and the anti-shake drive unit 65a), so that part of the second connecting band 46a is bent below the optical lens 10 and the light turning element 30, so that part of the second connecting band 46a is arranged in the connecting band accommodating cavity 614a of the fixed base 61a, thereby optimizing the spatial configuration in the camera module 1 and reducing the size of the camera module 1. In other words, in this example, part of the first connecting band 45a (i.e., the first bending portion 453a) and part of the second connecting band 46a (i.e., the second bending portion 463a) are bent and arranged in the connecting band accommodating cavity 614a below the optical lens 10 and the light turning element 30, so that the spatial configuration in the camera module 1 is optimized and the length of the camera module 1 is avoided from increasing.

[0303] It is worth mentioning that the second lead-out portion 464a of the second connecting belt 46a can also be fixed to the fixed base 61a or the upper cover 610a, so that the second bending portion 463a, the second side connecting portion 462a and the second connecting portion 461a located inside the camera module 1 are not affected by external factors, thereby further increasing the resistance exerted on the driving device 60 by the photosensitive component 40.

[0304] Further referring to Figure 10, in another embodiment of the present application, when the light deflecting element 30 is implemented as a parallelogram prism, the optical lens 10 and the photosensitive component 40 are arranged on different sides relative to the light deflecting element 30. For example, in a specific example of the present application, the optical lens 10 is arranged on the first surface 31 of the light deflecting element 30, and the photosensitive component 40 is arranged on the third surface 33 opposite to the first surface 31.

[0305] When the driver 60 is implemented as a chip driver assembly, it drives the photosensitive assembly 40 to move relative to the optical lens 10 and the light deflecting element 30, thereby achieving optical focus and / or optical image stabilization. The positions of various components within the driver 60 change with the position of the photosensitive assembly 40, requiring adjustments to the internal structure of the driver 60 and the positions of the components. However, it should be understood that the principles underlying most components are similar, so the following will only briefly describe these adjustments and improvements.

[0306] The optical lens 10 is positioned above the light deflecting element 30 and corresponds to the light entrance area 311 of the light deflecting element 30. The photosensitive assembly 40 is positioned below the light deflecting element 30 and corresponds to the light exit area 312 of the light deflecting element 30. In this embodiment, the fixed base 61a, frame 63a, and movable carrier 66a are positioned sequentially in height, with the frame 63a positioned between the fixed base 61a and the movable carrier 66a. The movable carrier 66a is positioned at the lowest position of the three.

[0307] In this embodiment, an anti-shake magnetic element is insert-molded into the movable carrier 66a. The anti-shake magnetic element is positioned below at least one anti-shake magnet 651a to magnetically attract the at least one anti-shake magnet 651a, thereby clamping at least three balls 671a disposed between the frame 63a and the movable carrier 66a. Furthermore, the frame cover 630a is vertically secured to the bottom surface of the frame 63a, confining the movable carrier 66a within the cavity formed by the frame cover 630a and the frame 63a.

[0308] Furthermore, the movable carrier 66a and the frame 63a extend upward from the bottom of the driving device 60, and the top surfaces of the movable carrier 66a and the frame 63a can be higher or lower than the top surface of the light turning element 30. When the top surfaces of the movable carrier 66a and the frame 63a are lower than the top surface of the light turning element 30, the height of the driving device 60 can be lowered.

[0309] Figures 11 to 14 show another embodiment of the driving device 60 of the present application. Specifically, Figure 11 shows a cross-sectional view of the camera module 1 along the length direction (i.e., the X-axis direction defined above), the camera module 1 includes a driving device 60 of another embodiment of the present application and an optical lens 10, a light deflection element 30, a filter assembly 50, and a photosensitive assembly 40 disposed in the driving device 60, wherein the photosensitive assembly 40 is disposed on the light-emitting side of the light deflection element 30, the optical lens 10 is disposed on the light-incident side of the light deflection element 30, and the light emitted by the optical lens 10 is transmitted to the multiple light deflection elements 30. After multiple reflections on the reflective surface, the light is emitted from the light deflection element 30 and reaches the photosensitive component 40. The light deflection element 30 is fixed to the fixed part of the driving device 60, and the photosensitive component 40 is fixed to the movable part of the driving device 60. The optical lens 10 is directly or indirectly fixed to the light deflection element 30, and the filter component 50 is directly or indirectly fixed to the photosensitive component 40. The driving device 60 can drive the photosensitive component 40 to move relative to the light deflection element 30, thereby changing the optical performance of the camera module 1 by moving the chip. Further, Figure 12 shows a cross-sectional view of the camera module 1 along the width direction (i.e., the Y-axis direction defined above); Figure 13 shows an exploded view of the camera module 1, from which the implementation method of the focus function of the camera module 1 can be understood; Figure 14 shows an exploded view of a part of the structure of the driving device 60, from which the implementation method of the anti-shake function can be understood.

[0310] As shown in Figures 11 to 14, the driving device 60 includes a frame 63b, a movable carrier 66b, and an anti-shake drive unit 65b. The movable carrier 66b is movably disposed within the frame 63b, and the anti-shake drive unit 65b is disposed between the frame 63b and the movable carrier 66b, such that the movable carrier 66b is driven by the anti-shake drive unit 65b to move horizontally relative to the frame 63b. In other words, the driving device 60 is configured to drive the photosensitive assembly 40 to move. The photosensitive assembly 40 is movably disposed at the end of the driving device 40 away from the optical lens 10.

[0311] Specifically, as shown in Figures 11, 12, and 14, the photosensitive assembly 40 is fixed to the movable carrier 66b in a direction facing the light deflecting element 30. Thus, the photosensitive assembly 40 moves with the movable carrier 66b, achieving chip anti-shake. In other words, in one specific example, the photosensitive assembly 40 is fixed above the movable carrier 66b. It should be understood that, in this application, the direction in which the photosensitive assembly 40 faces the light deflecting element 30 refers to the direction in which the photosensitive chip 41 of the photosensitive assembly 40 faces the light deflecting element 30, and the photosensitive chip 41 of the photosensitive assembly 40 faces the light deflecting element 30 to receive light emitted by the light deflecting element 30. In other words, compared to conventional upright modules, the photosensitive assembly 40 is fixed to the movable carrier 66b in an inverted position. The side of the chip circuit board 42 of the photosensitive assembly 40 facing the light deflecting element 30 is referred to as the front side of the chip circuit board 42. In one specific example, the movable carrier 66b is fixed to the front side of the chip circuit board 42. It is worth mentioning that the movable carrier 66 b can be directly fixed to the chip circuit board 42 by gluing; the movable carrier 66 b can also be indirectly fixed to the chip circuit board 42 by being fixed to the filter element bracket 52 of the filter assembly 50 .

[0312] An air gap is defined between the movable carrier 66b and the light deflecting element 30, and between the movable carrier 66b and the frame 63b, respectively. This allows the anti-shake drive unit 65b to drive the movable carrier 66b to move horizontally (i.e., perpendicular to the optical axis of the optical lens 10) relative to the frame 63b and the light deflecting element 30, thereby implementing the chip anti-shake function. It should be understood that, in this application, the horizontal portions of the air gaps formed between the movable carrier 66b and the light deflecting element 30, and between the movable carrier 66b and the frame 63b, are suitable for adjustment in implementing the chip anti-shake function. In one specific example, the movable carrier 66b is frame-shaped and is disposed around the light deflecting element 30.

[0313] The frame 63b is arranged on the outside of the movable carrier 66b, and the anti-shake drive unit 65b is arranged between the movable carrier 66b and the frame 63b. The anti-shake drive unit 65b includes at least one anti-shake magnet 651b and at least one anti-shake coil 652b. The at least one anti-shake magnet 651b is fixed to one of the movable carrier 66b and the frame 63b, and the at least one anti-shake coil 652b is fixed to the other of the movable carrier 66b and the frame 63b. The at least one anti-shake magnet 651b and the at least one anti-shake coil 652b are arranged relative to each other, so that the movable carrier 66b can be driven to move relative to the frame 63b by the magnetic force between the at least one anti-shake magnet 651b and the at least one anti-shake coil 652b to realize the chip anti-shake function.

[0314] In a specific example, at least one anti-shake magnet 651b is arranged on the frame 63b, at least one anti-shake coil 652b is arranged on the movable carrier 66b, at least one anti-shake magnet 651b includes a first anti-shake magnet 6511b and a second anti-shake magnet 6512b, at least one anti-shake coil 652b includes a first anti-shake coil 6521b and a second anti-shake coil 6522b, the first anti-shake magnet 6511b and the second anti-shake magnet 6512b are arranged on two adjacent sides of the frame 63b, the first anti-shake coil 6521b and the second anti-shake coil 6522b are arranged on two adjacent sides of the movable carrier 66b, and the first anti-shake coil 6521b is arranged opposite to the first anti-shake magnet 6511b, and the second anti-shake coil 6522b is arranged opposite to the second anti-shake magnet 6512b. In other words, the first anti-shake magnet 6511b and the first anti-shake coil 6521b are horizontally arranged between the frame 63b and the movable carrier 66b, and the second anti-shake magnet 6512b and the second anti-shake coil 6522b are horizontally arranged between the frame 63b and the movable carrier 66b. The anti-shake drive unit 65b includes at least one anti-shake magnet 651b and at least one anti-shake coil 652b arranged horizontally relative to each other. The horizontal direction refers to a direction perpendicular to the optical lens 10. In this way, the relative area between the first anti-shake magnet 6511b and the first anti-shake coil 6521b and the relative area between the second anti-shake magnet 6512b and the second anti-shake coil 6522b can be increased while maintaining a relatively small lateral dimension (length and width), thereby providing a larger horizontal driving force. In particular, at least one anti-shake coil 652b is arranged on the inner side of at least one anti-shake magnet 651b, so that at least one anti-shake coil 652b is arranged on the movable carrier 66b, and the photosensitive component 40 is also fixed to the movable carrier 66b, so that at least one anti-shake coil 652b is electrically connected to the photosensitive component 40, so that the anti-shake circuit board 653b used for electrically conducting at least one anti-shake coil 652b and the photosensitive component 40 can move with the movable carrier 66b, and the anti-shake circuit board 653b can be stationary relative to at least one anti-shake coil 652b and the photosensitive component 40, so that the anti-shake circuit board 653b will not generate resistance to the movement of the photosensitive component 40.

[0315] It is worth mentioning that the two adjacent side surfaces where the first anti-shake magnet 6511b and the second anti-shake magnet 6512b are located in the frame 63b are perpendicular to each other, and the two adjacent side surfaces where the first anti-shake coil 6521b and the second anti-shake coil 6522b are located in the movable carrier 66b are perpendicular to each other. In this way, the magnetic force between the first anti-shake magnet 6511b and the first anti-shake coil 6521b can drive the movable carrier 66b to move along the first horizontal direction relative to the frame 63b, and the magnetic force between the second anti-shake magnet 6512b and the second anti-shake coil 6522b can drive the movable carrier 66b to move along the second horizontal direction relative to the frame 63b. The second horizontal direction and the first horizontal direction are perpendicular to each other. That is, in this example, in the process of realizing chip anti-shake, at least one anti-shake coil 652b (the first anti-shake coil 6521b and the second anti-shake coil 6522b) serves as a mover, and at least one anti-shake magnet 651b (the first anti-shake magnet 6511b and the second anti-shake magnet 6512b) serves as a stator.

[0316] Specifically, the frame 63b has an opening facing the light deflecting element 30. The frame 63b includes an integrally formed first frame portion 635b, a second frame portion 637b, and a frame connecting portion 636b. The first frame portion 635b and the second frame portion 637b are respectively connected to the ends of the frame connecting portion 636b and are perpendicular to the frame connecting portion 636b, thereby forming a "Π" shape in the frame 63b. This avoids the position of the light deflecting element 30 and reduces the size of the drive device 60. The first anti-shake magnet 6511b is mounted on the inner side of the first frame portion 635b, which has a groove to accommodate the first anti-shake magnet 6511b. The second anti-shake magnet 6512b is mounted on the inner side of the frame connecting portion 636b, which also has a groove to accommodate the second anti-shake magnet 6512b. This reduces the size of the drive device 60 and the camera module 1. In other words, the first anti-shake magnet 6511b and the second anti-shake magnet 6512b are mounted on two adjacent inner side surfaces of the frame 63b. It should be understood that the "Π" shape of the frame 63b can be seen when looking down at the frame 63b from a height direction.

[0317] Correspondingly, the movable carrier 66b is also provided with two through-holes to accommodate the first and second anti-shake coils 6521b and 6522b, respectively, thereby reducing the size of the drive device 60. Specifically, the anti-shake drive unit 65b further includes an anti-shake circuit board 653b. The first and second anti-shake coils 6521b and 6522b are respectively fixed to and electrically connected to the anti-shake circuit board 653b. The anti-shake circuit board 653b surrounds and is attached to the outer surface of the movable carrier 66b, allowing the first and second anti-shake coils 6521b and 6522b to be exposed from the two through-holes of the movable carrier 66b and to face the first and second anti-shake magnets 6511b and 6512b, respectively. The anti-shake circuit board 653b is further electrically connected to the chip circuit board 42, thereby providing driving power to the anti-shake drive unit 65b via the chip circuit board 42 of the photosensitive assembly 40. The anti-shake circuit board 653b can be a flexible circuit board or a rigid-flexible circuit board, so that the anti-shake circuit board 653b can be bent around the outer side of the movable carrier 66b. It should be understood that in the above example, the anti-shake circuit board 653b is disposed between the first anti-shake coil 6521b and the first anti-shake magnet 6511b, and between the second anti-shake coil 6522b and the second anti-shake magnet 6512b.

[0318] It is worth noting that in this embodiment, as shown in Figures 11 and 12 , because the first and second anti-shake magnets 6511b and 6512b are disposed on the side of the frame 63b, the bottom surfaces of the first and second anti-shake magnets 6511b and 6512b can be lower than the top surface of the light deflection element 30. The downward extension of the first and second anti-shake magnets 6511b and 6512b increases the relative area between the first and second anti-shake magnets 6511b and 6512b and the first and second anti-shake coils 6521b and 6522b, thereby enhancing the driving force of the anti-shake drive unit 65b.

[0319] In this embodiment, the drive device 60 also includes an anti-shake support portion 67b and an anti-shake magnetic member 650b. The anti-shake support portion 67b is disposed between the frame 63b and the movable carrier 66b to maintain an air gap between the frame 63b and the movable carrier 66b, thereby reducing the resistance encountered by the movable carrier 66b when moving relative to the frame 63b. In a specific example, the anti-shake support portion 67b can be implemented as a ball 671b, and the anti-shake support portion 67b includes at least three balls 671b. Specifically, the movable carrier 66b includes a carrier body 662b and a carrier extension portion 663b extending outward from the top of the carrier body 662b. The carrier extension portion 663b extends above the frame 63b. At least three balls 671b are disposed along the height direction between the frame 63b and the carrier extension portion 663b of the movable carrier 66b to maintain a fixed gap between the frame 63b and the movable carrier 66b in the height direction. Specifically, the at least three balls 671b are disposed above the frame 63b and below the carrier extension portion 663b. It should be understood that the anti-shake support portion 67b can also be implemented as other elements such as a spring or a slider.

[0320] The anti-shake magnetic component 650b is fixed to the movable carrier 66b and is arranged above at least one anti-shake magnet 651b (the first anti-shake magnet 6511b and / or the second anti-shake magnet 6512b). The anti-shake magnetic component 650b is made of a material suitable for being attracted by magnets. It is magnetically attracted to at least one anti-shake magnet 651b so that the movable carrier 66b is adsorbed toward the frame 63b in the height direction. The movable carrier 66b and the frame 63b clamp at least three balls 671b in the height direction. It should be understood that the anti-shake magnetic component 650b can be fixed to the movable carrier 66b by insert molding or bonding. For example, the anti-shake magnetic component 650b is fixed in the carrier extension portion 663b of the movable carrier 66b by insert molding.

[0321] Furthermore, to restrict the movement of ball 671b, frame 63b includes at least three first ball grooves 634b formed on the top surface of frame 63b, and movable carrier 66b includes at least three second ball grooves 661b formed on the bottom surface of carrier extension 663b. The positions of first ball grooves 634b and second ball grooves 661b correspond, and the directions of extension of first ball grooves 634b and second ball grooves 661b are perpendicular to each other, forming a cross. The bottom and top of ball 671b are respectively accommodated in first ball grooves 634b and second ball grooves 661b, and are allowed to roll along the first ball grooves 634b and second ball grooves 661b, respectively.

[0322] In a specific example, as shown in Figure 14, the anti-shake support part 67b includes four balls 671b, four first ball grooves 634b are formed at the four corners of the top surface of the frame 63b, and four second ball grooves 661b corresponding to the four first ball grooves 634b are formed at the four corners of the bottom surface of the carrier extension part 663b. The anti-shake magnetic suction part 650b fixed in the extension part of the movable carrier 66b is magnetically attracted to the first anti-shake magnet 6511b and the second anti-shake magnet 6512b so that the four balls 671b are respectively clamped between the four corners of the frame 63b and the four corners of the movable carrier 66b.

[0323] It is worth mentioning that the driving device 60 further includes a frame cover 630b, which is fixed to the top surface of the frame 63b in the height direction so that the movable carrier 66b is confined in the accommodating cavity formed by the frame cover 630b and the frame 63b. It should be understood that during a fall, the magnetic attraction between the anti-shake magnetic element 650b and the anti-shake magnet 651b is difficult to maintain the positional relationship between the movable carrier 66b and the frame 63b. After the movable carrier 66b has a large displacement relative to the frame 63b, the ball 671b will be separated from the first ball groove 634b and the second ball groove 661b. Therefore, in the present application, a frame cover 630b is further provided to limit the height movement of the movable carrier 66b through the frame cover 630b, thereby preventing the ball 671b from falling off. Specifically, the carrier extension portion 663b of the movable carrier 66b overlaps with the frame cover 630b in the height direction. When the movable carrier 66b moves along the height direction toward the direction away from the light turning element 30, the carrier extension portion 663b of the movable carrier 66b abuts against the frame cover 630b, thereby confining the movable carrier 66b in the accommodating cavity formed by the frame cover 630b and the frame 63b.

[0324] Furthermore, the drive device 60 can also implement a chip focusing function. Specifically, as shown in Figures 12 and 13, the drive device 60 also includes a fixed base 61b and a focus drive unit 62b disposed between the fixed base 61b and the frame 63b. The frame 63b is movably disposed within the fixed base 61b, and the focus drive unit 62b is disposed between the fixed base 61b and the frame 63b, so that the frame 63b is driven by the focus drive unit 62b to move in the height direction relative to the fixed base 61b. As the frame 63b moves, the movable carrier 66b, the anti-shake drive unit 65b, the anti-shake support unit 67b, and the anti-shake magnetic element 650b disposed within the frame 63b also move with the movement of the frame 63b. Consequently, the photosensitive component 40 fixed to the movable carrier 66b also moves with the movement of the frame 63b, thereby implementing the chip focusing function.

[0325] The drive device 60 also includes an upper cover 610b fixed to the fixed base 61b. The upper cover 610b and the fixed base 61b form a housing chamber to accommodate the focus drive unit 62b, the frame 63b, the frame cover 630b, the anti-shake drive unit 65b, and the movable carrier 66b. The upper cover 610b has a lens opening 611b, so that the optical lens 10 can extend from the drive device 60 through the lens opening 611b. There is an air gap between the frame 63b and the fixed base 61b to allow the focus drive unit 62b to drive the frame 63b to move in the height direction relative to the fixed base 61b, thereby realizing the chip focusing function. It should be understood that in the present application, the height portion of the air gap formed between the frame 63b and the fixed base 61b is suitable for being adjusted in the implementation of the chip focusing function.

[0326] Referring to Figure 14 , the fixed base 61b includes a base body 611b, a supporting portion 613b, and a focus fixing portion 612b. The supporting portion 613b is fixed to the center of the base body 611b, and the focus fixing portion 612b is fixed to one side of the base body 611b, specifically, to a long side of the base body 611b. It should be understood that the supporting portion 613b and the focus fixing portion 612b can be fixed to the base body 611b separately by bonding or integrally forming.

[0327] The supporting portion 613b has a supporting cavity for mounting the light deflecting element 30. In other words, the light deflecting element 30 is mounted on the supporting portion 613b, and the shape of the supporting cavity of the supporting portion 613b is adapted to the shape of the light deflecting element 30. For example, when the light deflecting element 30 is implemented as a trapezoidal prism, the supporting cavity of the supporting portion 613b has a size that gradually decreases from top to bottom.

[0328] The focus drive unit 62b is arranged between the frame 63b and the focus fixing unit 612b of the fixed base 61b. The focus drive unit 62b includes a pair of focus magnets 621b and a pair of focus coils 622b. The focus magnet 621b is fixed to one of the frame 63b and the focus fixing unit 612b, and the focus coil 622b is fixed to the other of the frame 63b and the focus fixing unit 612b. The focus magnet 621b and the focus coil 622b are arranged relative to each other, so that the magnetic force between the focus magnet 621b and the focus coil 622b can drive the frame 63b to move in the height direction relative to the fixed base 61b to realize the chip focusing function.

[0329] In one specific example, the focus magnet 621b is disposed on a side surface of the frame 63b, and the focus coil 622b is disposed on the focus fixing portion 612b of the fixed base 61b, with the focus coil 622b and the focus magnet 621b being disposed opposite each other. In other words, the focus coil 622b and the focus magnet 621b are disposed horizontally between the frame 63b and the focus fixing portion 612b of the fixed base 61b, and the focus drive unit 62b includes the focus coil 622b and the focus magnet 621b disposed opposite each other in the horizontal direction, where the horizontal direction refers to a direction perpendicular to the optical lens 10. In this way, a larger driving force in the height direction can be provided with a smaller lateral dimension (dimensions in the length and width directions).

[0330] It should be understood that during chip focusing, the focus coil 622b, fixed to the focus fixing portion 612b, drives the focus magnet 621b to move in the height direction relative to the focus coil 622b. As a result, the frame 63b, fixed to the focus magnet 621b, moves in the height direction as the focus magnet 621b moves. In other words, in this example, during chip focusing, the focus magnet 621b acts as a mover, and the focus coil 622b acts as a stator.

[0331] Furthermore, the focus drive unit 62b also includes a focus circuit board 623b, and the focus coil 622b is fixed and electrically connected to the focus circuit board 623b. The focus circuit board 623b is fixed to the focus fixing unit 612b, so that the focus coil 622b is indirectly fixed to the focus fixing unit 612b through the focus circuit board 623b. In a specific example, the focus circuit board 623b is attached to the outer side surface of the focus fixing unit 612b, and a through hole is provided on the focus fixing unit 612b to expose the focus coil 622b and oppose the focus magnet 621b. The through hole on the focus fixing unit 612b accommodates the focus coil 622b, which can reduce the lateral size of the drive device 60. It should be understood that the outer side surface of the focus fixing unit 612b refers to the side of the focus fixing unit 612b away from the frame 63b. It is worth mentioning that the focusing circuit board 623b is further electrically connected to the chip circuit board 42. The focusing circuit board 623b can be a flexible circuit board or a soft-hard combination board. In this way, the focusing circuit board 623b can be arranged in the driving device 60 in a bent state so that the focusing circuit board 623b can be extended to a position that is convenient for electrical connection with the chip circuit board 42.

[0332] Accordingly, the focusing magnet 621b is mounted on the outer side surface of the frame 63b so that a smaller distance can be maintained between the focusing magnet 621b and the focusing coil 622b, thereby enhancing the magnetic force between the focusing magnet 621b and the focusing coil 622b. Specifically, the focusing magnet 621b is mounted on the outer side surface of the second frame portion 637b, and the outer side surface of the second frame portion 637b has a groove to accommodate the focusing magnet 621b. In this way, the size of the drive device 60 and the camera module 1 can be reduced. It should be understood that the outer side surface of the frame 63b refers to the side of the frame 63b facing the fixed base 61b or the upper cover 610b, and the outer side surface of the second frame portion 637b refers to the side of the second frame portion 637b facing the focus fixing portion 612b.

[0333] In the driving device 60 shown in Figures 11 to 14, the first frame portion 635b and the frame connecting portion 636b are respectively used to install the first anti-shake magnet 6511b and the second anti-shake magnet 6512b, and the second frame portion 637b is used to install the focus magnet 621b. The frame 63b includes an anti-shake frame 633b and a focus frame 631b. The first frame portion 635b and the frame connecting portion 636b form an "L"-shaped anti-shake frame 633b, and the second frame portion 637b forms a focus frame 631b. The anti-shake frame 633b and the focus frame 631b are connected by integral molding. It is worth mentioning that the focusing magnet 621b and at least one anti-shake magnet 651b (the first anti-shake magnet 6511b and the second anti-shake magnet 6512b) are both fixed to the side of the frame 63b, wherein the focusing magnet 621b is fixed to the outer side surface of the frame 63b, and at least one anti-shake magnet 651b is fixed to the inner side surface of the frame 63b. In particular, at least one anti-shake magnet 651b is not arranged on the top surface of the frame 63b, so that the lateral size of the driving device 60 is relatively small. It should be understood that in this embodiment, the first anti-shake coil 6521b and the second anti-shake coil 6522b are located on the inner side of the first anti-shake magnet 6511b and the second anti-shake magnet 6512b, and the focusing coil 622b is located on the outer side of the focusing magnet 621b. In this way, the first anti-shake coil 6521b and the second anti-shake coil 6522b can be directly electrically connected to the chip circuit board 42 of the photosensitive component 40 from the inside, while the focusing coil 622b is electrically connected to the photosensitive component 40 from the outside, thereby optimizing the electrical connection setting method of the camera module 1.

[0334] It is worth noting that in this embodiment, as shown in Figure 12 , because the focus magnet 621b is disposed on the side of the focus fixing portion 612b of the fixing base 61b, the bottom surface of the focus magnet 621b can be lower than the top surface of the light deflection element 30. The downward extension of the focus magnet 621b increases the area of ​​contact between the focus magnet 621b and the focus coil 622b, thereby enhancing the driving force of the focus drive unit 62b.

[0335] It is worth mentioning that, in this embodiment, the focus magnet 621 b , the first anti-shake magnet 6511 b and the second anti-shake magnet 6512 b are arranged on the peripheral side of the light turning element 30 .

[0336] In this embodiment, the driving device 60 also includes a pair of focusing guides 64b and a pair of focusing magnetic members 620b. The focusing guide 64b is arranged between the frame 63b and the fixed base 61b so as to maintain an air gap between the frame 63b and the fixed base 61b, thereby reducing the resistance encountered by the frame 63b when it moves relative to the fixed base 61b. In a specific example, the focusing guide 64b can be implemented as a guide rod 641b, and the focusing guide 64b includes two guide rods 641b. Specifically, the two guide rods 641b are vertically arranged between the second frame portion 637b of the frame 63b and the focus fixing portion 612b of the fixed base 61b so as to maintain a fixed gap between the frame 63b and the fixed base 61b in the horizontal direction. Furthermore, in this embodiment, two guide rods 641b are respectively provided on both sides of the focus driving portion 62b, and the two guide rods 641b have the same size to prevent the frame 63b and the focus fixing portion 612b from tilting.

[0337] The focusing magnetic member 620b is fixed to the focusing fixing portion 612b of the fixed base 61b by being attached to the back of the focusing circuit board 623b. In this way, in the width direction, the focusing magnet 621b, the focusing coil 622b, the focusing circuit board 623b and the focusing magnetic member 620b are arranged in sequence. Among them, the side of the focusing circuit board 623b on which the focusing coil 622b is arranged is the front side of the focusing circuit board 623b, and the other opposite side is the back side of the focusing circuit board 623b. The focusing magnetic member 620b is made of a material suitable for being attracted by a magnet. It is magnetically attracted to the focusing magnet 621b so that the frame 63b is adsorbed toward the focusing fixing portion 612b of the fixed base 61b in the width direction. The frame 63b and the focusing fixing portion 612b of the fixed base 61b clamp the two guide rods 641b in the width direction. The focusing magnetic member 620b can be made of an iron-containing material.

[0338] In other words, the focus guide portion 64b is arranged between the second frame portion 637b of the frame 63b and the focus fixing portion 612b of the fixed base 61b, the focus magnetic component 620b is fixed to the focus fixing portion 612b, and the focus magnetic component 620b and the focus magnet 621b are magnetically attracted to each other so that the focus guide portion 64b is clamped between the second frame portion 637b of the frame 63b and the focus fixing portion 612b of the fixed base 61b.

[0339] In a specific example, two first guide rails 6123b extending in the height direction are formed on the inner side surface of the focus fixing portion 612b opposite the frame 63b, and two second guide rails 632b extending in the height direction are formed on the outer side surface of the frame 63b opposite the focus fixing portion 612b (i.e., the outer side surface of the second frame portion 637b). The two first guide rails 6123b and the two second guide rails 632b are respectively provided. Two guide rods 641b are respectively provided between the two first guide rails 6123b and the two second guide rails 632b, and are clamped between the frame 63b and the focus fixing portion 612b by the magnetic attraction between the focus magnetic member 620b and the focus magnet 621b.

[0340] It is worth mentioning that in one example of the present application, the two guide rods 641b may not be fixed, and they are only clamped by the frame 63b and the focus fixing part 612b; in another example of the present application, the positions of the two guide rods 641b may also be fixed, for example, they may be fixed to the fixed base 61b by fixing the bottom end of the guide rod 641b to the fixed base 61b and / or fixing the top end of the guide rod 641b to the upper cover 610b, or, the two guide rods 641b are restricted between the upper cover 610b and the fixed base 61b only by the snap fit between the upper cover 610b and the fixed base 61b.

[0341] It is worth noting that in the above embodiment, since the light deflection element 30 disposed between the optical lens 10 and the photosensitive component 40 is relatively long, in order to reduce the overall size of the camera module 1, the frame 63b has an opening toward the light deflection element 30, thereby forming a "Π" shape around the light deflection element 30. Consequently, the frame 63b has only three sides on which the first anti-shake magnet 6511b, the second anti-shake magnet 6512b, and the focus magnet 621b can be disposed. The first and second anti-shake magnets 6511b, 6512b need to be disposed perpendicular to each other to achieve translation in two perpendicular directions. Therefore, one of the first and second anti-shake magnets 6511b, 6512b needs to be disposed on a short side of the drive device 60, while the other of the first and second anti-shake magnets 6511b, 6512b and the focus magnet 621b are disposed on two opposing long sides of the drive device 60.

[0342] Specifically, the first anti-shake magnet 6511b is mounted on the inner surface of the first frame portion 635b located on the long side of the drive device 60, the second anti-shake magnet 6512b is mounted on the inner surface of the frame connection portion 636b located on the short side of the drive device 60, and the focus magnet 621b is mounted on the outer surface of the second frame portion 637b located on the long side of the drive device 60. The focus magnet 621b, the first anti-shake magnet 6511b, and the second anti-shake magnet 6512b are flat rectangular parallelepipeds. The largest side of the focus magnet 621b is parallel to the largest side of the first anti-shake magnet 6511b, and the largest side of the focus magnet 621b is perpendicular to the largest side of the second anti-shake magnet 6512b. Accordingly, the focus coil 622b is parallel to the first anti-shake coil 6521b, and perpendicular to the second anti-shake coil 6522b.

[0343] Furthermore, in one example, the magnetic pole direction of the focusing magnet 621b is perpendicular to the magnetic pole direction of the first anti-shake magnet 6511b and the second anti-shake magnet 6512b, so that the driving direction of the focusing drive unit 62b is perpendicular to the driving direction of the anti-shake drive unit 65b. In this application, the magnetic pole direction of the magnet refers to the direction in which the S pole of the magnet points to the N pole. Accordingly, the focusing coil 622b, the first anti-shake coil 6521b and the second anti-shake coil 6522b are all runway-type coils, wherein the winding plane of the focusing coil 622b and the winding plane of the first anti-shake coil 6521b are parallel to each other, and the winding plane of the focusing coil 622b and the winding plane of the second anti-shake coil 6522b are perpendicular to each other.

[0344] It should be understood that in this embodiment, due to the different dimensions of the focusing magnet 621b and the first anti-shake magnet 6511b, the focusing magnet 621b and the first anti-shake magnet 6511b are not symmetrically arranged. Accordingly, in one example, the optical lens 10, the light deflecting element 30, and the photosensitive component 40 are eccentrically arranged in the width direction within the driving device 60.

[0345] Furthermore, the photosensitive component 40 also includes a connecting circuit board 44, which is fixed and electrically connected to the chip circuit board 42 to provide electrical conduction between the chip circuit board 42 and external electronic devices. The applicant has found that when the photosensitive component 40 is driven by the driving device 60 to move, the connecting circuit board 44 becomes one of the sources of resistance to the movement of the photosensitive component 40. Therefore, in this application, the applicant further improves the connecting circuit board 44 of the photosensitive component 40 to reduce the resistance encountered by the photosensitive component 40 when being driven to achieve chip anti-shake or chip focus.

[0346] 11 , 13 , and 14 , the connection circuit board 44 includes a first connection strip 45b, which includes a first connection portion 451b, a first side connection portion 452b, a first bend portion 453b, and a first lead portion 454b, which are sequentially connected. The first connection portion 451b connects the chip circuit board 42 and the first side connection portion 452b, and the first bend portion 453b connects the first side connection portion 452b and the first lead portion 454b. It should be understood that the first connection portion 451b, the first side connection portion 452b, the first bend portion 453b, and the first lead portion 454b are electrically connected. The first connection strip 45b is connected to the chip circuit board 42 via the first connection portion 451b and is electrically connected, thereby enabling the chip circuit board 42 to be electrically connected to an external device or equipment via the first lead portion 454b of the first connection strip 45b. It is worth mentioning that in the present application, the first connecting strip 45b can be a flexible circuit board or a hard-soft board, so that the first connecting strip 45b can be bent to adapt to the space inside the camera module 1.

[0347] Specifically, the first connecting portion 451b extends laterally from the chip circuit board 42 in a direction away from the chip circuit board 42, one end of the first connecting portion 451b is connected to the chip circuit board 42, and the other end of the first connecting portion 451b is bent downward and connected to one end of the first side connecting portion 452b. The first side connecting portion 452b extends and bends around the circumference of the light turning element 30 and the optical lens 10, so that the first side connecting portion 452b is bent from the long side of the camera module 1 to the short side of the camera module 1, and the other end of the first side connecting portion 452b is connected to one end of the first bending portion 453b. One end of the first bending portion 453b is connected to the bottom of the other end of the first side connecting portion 452b, and the other end of the first bending portion 453b is connected to the first lead-out portion 454b. The first bending portion 453b is bent and arranged below the first side connecting portion 452b. In one specific example, the first bent portion 453b is horizontally bent and disposed below the first side connecting portion 452b. It should be understood that, as shown in the drawings herein, the direction of the optical lens 10 relative to the light deflecting element 30 is considered "up," and the opposite direction is considered "down." In other words, the light deflecting element 30 is below the optical lens 10.

[0348] It should be understood that the provision of the first side connection portion 452b reduces the resistance of the photosensitive component 40 from the connection circuit board 44 when it moves in the horizontal direction, and the provision of the first bent portion 453b reduces the resistance of the photosensitive component 40 from the connection circuit board 44 when it moves in the height direction. In particular, in the present application, the driving device 60 can drive the photosensitive component 40 to move in the height direction to a distance of at least 2 mm, and the first bent portion 453b can be extended and retracted in the height direction to meet the requirements of the photosensitive component 40 moving in the height direction. Furthermore, the first bent portion 453b can be bent multiple times to allow the first bent portion 453b to have a longer extension and retraction distance in the height direction.

[0349] It is worth mentioning that in order to design the size of the camera module 1 to be smaller, in the present application, the fixed base 61b also includes a connecting belt accommodating cavity 614b formed between the base body 611b and the supporting portion 613b. The connecting belt accommodating cavity 614b is arranged on the side of the fixed base 61b close to the optical lens 10. The connecting belt accommodating cavity 614b is located below the optical lens 10 and the light turning element 30. The first bending portion 453b is accommodated in the connecting belt accommodating cavity 614b, thereby avoiding an increase in the length of the camera module 1. The first connecting strip 45b extends from the chip circuit board 42 toward the side closest to the optical lens 10 (i.e., away from the focus drive unit 62b and the anti-shake drive unit 65b). Portions of the first connecting strip 45b are bent below the optical lens 10 and the light deflecting element 30, allowing them to be positioned within the connecting strip receiving cavity 614b of the fixed base 61b. This optimizes the spatial configuration within the camera module 1 and reduces the size of the camera module 1. It is worth noting that "below" the light deflecting element 30 refers to below the top surface of the light deflecting element 30, that is, below the first surface 31 of the light deflecting element 30. Furthermore, "below" the light deflecting element 30 further refers to below the second surface 32 of the light deflecting element 30. Portions of the first connecting strip 45a are bent below an inclined surface (the second surface 32) of the light deflecting element 30, and the connecting strip receiving cavity 614a is located below an inclined surface (the second surface 32) of the light deflecting element 30.

[0350] It is worth mentioning that the first lead-out portion 454b of the first connecting belt 45b can be fixed to the fixed base 61b or the upper cover 610b, so that the first bent portion 453b, the first side connecting portion 452b, and the first connecting portion 451b located inside the camera module 1 are not affected by external factors, which further increases the resistance of the driving device 60 from the photosensitive component 40. For example, when the first lead-out portion 454b is not fixed, the movement of other devices or equipment connected to the camera module 1 may cause the first lead-out portion 454b to move, and the first bent portion 453b connected to the first lead-out portion 454b may also move. Ultimately, the resistance generated by the photosensitive component 40 increases.

[0351] Furthermore, in some embodiments, due to the improved specifications and increased functions of the photosensitive component 40, setting the first connecting band 45b only on one side will make the width of the first connecting band 45b too large. Therefore, the connecting circuit board 44 also includes a second connecting band 46b, and the second connecting band 46b is arranged on both sides of the chip circuit board 42 opposite to the first connecting band 45b.

[0352] In a specific example, the second connecting strip 46b includes a second connecting portion 461b and a second side connecting portion 462b, wherein the second connecting portion 461b connects the chip circuit board 42 and the second side connecting portion 462b. It should be understood that the second connecting portion 461b and the second side connecting portion 462b are electrically conductive, and the second connecting strip 46b is connected to the chip circuit board 42 through the second connecting portion 461b and electrically conductive, so that the chip circuit board 42 can be electrically connected to other components through the second connecting strip 46b on the opposite side of the first connecting strip 45b. It is worth mentioning that in the present application, the second connecting strip 46b can also be a flexible circuit board or a soft-rigid combination board, so that the second connecting strip 46b can be bent to adapt to the space inside the camera module 1.

[0353] In this example, the first connecting belt 45b and the second connecting belt 46b are arranged around the circumference of the optical lens 10 and the light deflection element 30, making full use of the fact that most of the components of the driving device 60 are arranged on the other side away from the optical lens 10. The camera module 1 has a feature that more space can be used on the side where the optical lens 10 is arranged, thereby optimizing the space configuration.

[0354] Specifically, the second connecting portion 461b extends laterally from the chip circuit board 42 in a direction away from the chip circuit board 42. One end of the second connecting portion 461b is connected to the chip circuit board 42, and the other end of the second connecting portion 461b is bent downward and connected to one end of the second side connecting portion 462b. The second side connecting portion 462b extends and bends around the periphery of the light deflecting element 30 and the optical lens 10, thereby bending the second side connecting portion 462b from the long side of the camera module 1 to the short side of the camera module 1. The other end of the second side connecting portion 462b is fixed to and electrically connected to the other end of the first side connecting portion 452b, thereby electrically connecting the second connecting strip 46b to an external device or equipment through the first bent portion 453b and the first lead-out portion 454b of the first connecting strip 45b.

[0355] It should be understood that the provision of the second connecting strip 46b reduces the width of the first connecting portion 451b of the first connecting strip 45b, thereby reducing the resistance experienced by the photosensitive component 40 during movement. Furthermore, providing both the first connecting strip 45b and the second connecting strip 46b on both sides of the chip circuit board 42 can further disperse the distribution of resistance.

[0356] In a specific example, the second connection portion 461b and the second side connection portion 462b of the second connection belt 46b are symmetrically arranged with the first connection portion 451b and the first side connection portion 452b of the first connection belt 45b, further balancing the resistance brought to the driving device 60 by the connecting circuit board 44.

[0357] The above describes the structure of the drive device 60 and camera module 1 when the photosensitive component 40 and optical lens 10 are located on the same side of the light deflecting element 30 in this application. Furthermore, in this application, the photosensitive component 40 and the optical lens 10 can also be located on either side of the light deflecting element 30. Accordingly, the internal structure of the drive device 60 and the position of the components need to be adjusted accordingly. However, it should be understood that the principles of most components are similar, so the following only briefly describes the adjustments and improvements.

[0358] As shown in Figures 2C and 15 , the optical lens 10 is positioned above the light deflecting element 30 and corresponds to the light entrance area 311 of the light deflecting element 30. The photosensitive assembly 40 is positioned below the light deflecting element 30 and corresponds to the light exit area 312 of the light deflecting element 30. In this embodiment, an anti-shake magnetic attraction 650b is insert-molded into the movable carrier 66b. The anti-shake magnetic attraction 650b is positioned below at least one anti-shake magnet 651b to magnetically attract the at least one anti-shake magnet 651b, thereby clamping at least three balls 671b disposed between the frame 63b and the movable carrier 66b. Furthermore, the frame cover 630b is fixed to the bottom surface of the frame 63b in the height direction so that the movable carrier 66b is confined within the accommodation cavity formed by the frame cover 630b and the frame 63b.

[0359] In the embodiments shown in Figures 2C and 15, the movable carrier 66b and the frame 63b extend upward from the bottom of the driving device 60, and the top surfaces of the movable carrier 66b and the frame 63b can be higher or lower than the top surface of the light deflection element 30. When the top surfaces of the movable carrier 66b and the frame 63b are lower than the top surface of the light deflection element 30, the height of the driving device 60 can be lowered.

[0360] Furthermore, mobile phones, tablets or other electronic devices currently on the market are usually equipped with multiple camera modules to form an array module, and the multiple camera modules are usually arranged close to each other. However, since the camera modules usually use voice coil motors driven by electromagnetic force, magnetic interference will occur between adjacent motors when they are arranged close to each other. Therefore, the present application further provides a new array module 100 design in order to solve the above-mentioned problem.

[0361] The array module 100 includes the camera module 1 shown in Figures 1 to 16 of the present application and a first sub-module 102 disposed adjacent to the camera module 1. The camera module 1 and the first sub-module 102 are disposed in the same direction to capture the same subject. The first sub-module 102 includes a first motor 1021, a first lens 1022 mounted in the first motor 1021, and a first connection circuit board 1023 for providing power to the first sub-module 102. The first motor 1021 may be a voice coil motor driven by electromagnetic force.

[0362] The first sub-module 102 also includes a first photosensitive assembly, which includes a first chip circuit board, a first photosensitive chip electrically connected to the first chip circuit board, and multiple electronic components. The first photosensitive chip is used to receive light focused by the first lens 1022 and form an image. The first connecting circuit board 1023 is electrically connected to the first chip circuit board of the first photosensitive assembly to provide driving power for the second photosensitive assembly. The first motor 1021 is fixed to the first photosensitive assembly and electrically connected to the first chip circuit board, thereby providing driving power to the first motor 1021 through the first chip circuit board.

[0363] In the present application, since the light deflection element 30 is in the shape of an elongated strip, the driving device 60 and the camera module 1 including the driving device 60 are also in the shape of an elongated strip. Therefore, in the longitudinal direction, the optical lens 10 of the camera module 1 is eccentrically arranged in the driving device 60, and the driving unit containing a magnet in the driving device 60 (the driving unit includes the front focus driving unit 62a (62b) and the anti-shake driving unit 65a (65b)) is eccentrically arranged on the other side of the driving device 60. That is, along the longitudinal direction, the camera module 1 includes a first area 1011 and a second area 1012 that are arranged opposite to each other in the longitudinal direction, wherein the optical lens 10 is arranged in the first area 1011 of the camera module 1, and the second area 1012 is arranged on the other side of the camera module 1 away from the first area 1011. The optical lens 10 is arranged away from the second area 1012, and the driving part including the magnet in the driving device 60 (the driving part includes the front focusing driving part 62a (62b) and the anti-shake driving part 65a (65b)) is arranged in the second area 1012 of the camera module 1.

[0364] In other words, the camera module includes a first region 1011 and a second region 1012 disposed opposite each other along the length direction. The camera module 1 includes an optical lens 10 and a drive device 60. The optical lens 10 is eccentrically disposed within the drive device 60. The optical lens 10 is disposed within the first region 1011, and the drive unit of the drive device 60, which includes a magnet, is disposed within the second region 1012. Specifically, the focus magnet 621a (621b) and at least one anti-shake magnet 651a (651b) are eccentrically disposed within the second region 1012 of the camera module 1.

[0365] Accordingly, as shown in FIG16 , the first sub-module 10 is disposed around the first region 1011 of the camera module 1, and the first sub-module 102 is disposed proximate to the first region 1011 of the camera module 1, thereby being away from the second region 1012 of the camera module 1. This reduces magnetic interference with the first sub-module 102 by the drive device 60 of the camera module 1. The first sub-module 102 is disposed adjacent to the first region 1011 of the camera module 1, which can reduce interference with the first sub-module 102 by magnets included in the drive unit of the camera module 1. In particular, when the first motor 1021 is implemented as a voice coil motor (VCM), the first sub-module 102 is disposed adjacent to the first region 1011 of the camera module 1, which can reduce magnetic interference between the drive device 60 and the first motor 1021.

[0366] Furthermore, the camera module 1 also includes a connecting circuit board 44 for providing power to the camera module 1. As shown in Figures 11, 14, and 16, the connecting circuit board 44 extends outward along the length of the camera module 1. Specifically, the camera module 1 is in the shape of an elongated strip, having two long sides and two short sides, with one short side being closer to the first region 1011 of the camera module 1. In one specific example, the two short sides are parallel to each other, the two long sides are parallel to each other, and the long side is perpendicular to the short side. The connecting circuit board 44 of the camera module 1 extends outward from the short side of the camera module 1 closer to the first region 1011. Therefore, the first sub-module 102 is further arranged adjacent to one of the long sides of the camera module 1, so that the connecting circuit board 44 of the camera module 1 does not interfere with the installation of the first sub-module 102, allowing the first sub-module 102 and the camera module 1 to be arranged closer together, thereby reducing the lateral size of the array module 100. Correspondingly, the first connecting circuit board 1023 of the first sub-module 102 extends outward from one side of the first sub-module 102 that is not close to the camera module 1, and the extension direction of the first connecting circuit board 1023 can be parallel to the extension direction of the connecting circuit board 44 of the camera module 1.

[0367] It is worth mentioning that the array module 100 may further include a module bracket, in which the first sub-module 102 and the camera module 1 are installed to maintain the relative position between the first sub-module 102 and the camera module 1 .

[0368] It should be understood that in this embodiment, the optical lens 10 of the camera module 1 has a long focal length, that is, the optical lens 10 is a telephoto lens, and the camera module 1 can be a telephoto camera module. Accordingly, the first sub-module 102 can be a wide-angle camera module, and the first lens 1022 can be a wide-angle lens, so that the first sub-module 102 and the camera module 1 can form a wide-angle + telephoto camera combination.

[0369] It should be understood that in this embodiment, since the optical lens 10 of the camera module 1 is vertically arranged in the driving device 60, the optical axis of the first lens 1022 of the first sub-module 102 can be parallel to the optical axis of the optical lens 10 of the camera module 1.

[0370] Continuing with FIG16 , the array module 100 may further include a second sub-module 103, which is positioned adjacent to the other long side of the camera module 1 and proximate to the first region 1011 of the camera module 1. The second sub-module 103 is positioned in the same direction as the camera module 1 to capture the same subject. In one specific example, the first sub-module 102 and the second sub-module 103 are symmetrically positioned around the first region 1011 of the camera module 1.

[0371] The second sub-module 103 includes a second motor 1031, a second lens 1032 mounted in the second motor 1031, and a second connection circuit board 1033 for providing power to the second sub-module 103. The second motor 1031 may be a voice coil motor driven by electromagnetic force. The second sub-module 103 is positioned near the first region 1011 of the camera module 1, thereby being positioned away from the second region 1012 of the camera module 1. This reduces magnetic interference with the second motor 1031 of the second sub-module 103 by the drive device 60 of the camera module 1. Furthermore, the second sub-module 103 is positioned on the other long side of the camera module 1 so that the connection circuit board 44 of the camera module 1 does not interfere with the installation of the second sub-module 103. This allows the second sub-module 103 and the camera module 1 to be positioned closer together, thereby reducing the lateral dimensions of the array module 100. Correspondingly, the second connecting circuit board 1033 of the second sub-module 103 extends outward from one side of the second sub-module 103 that is not close to the camera module 1, and the extension direction of the second connecting circuit board 1033 can be perpendicular to the extension direction of the connecting circuit board 44 of the camera module 1.

[0372] The second sub-module 103 also includes a second photosensitive component, which includes a second chip circuit board and a second photosensitive chip electrically connected to the second chip circuit board and a plurality of electronic components. The second photosensitive chip is used to receive the light focused by the second lens 1032 and form an image. The second connecting circuit board 1033 is electrically connected to the second chip circuit board of the second photosensitive component to provide a driving power source for the second photosensitive component. The second motor 1031 is fixed to the second photosensitive component and electrically connected to the second chip circuit board, thereby providing a driving power source to the second motor 1021 through the second chip circuit board. It is worth mentioning that the second sub-module 103 can also be installed in the module bracket to maintain the relative position between the second sub-module 103 and the camera module 1 and the first sub-module 102.

[0373] It should be understood that in this embodiment, the second sub-module 103 can be a wide-angle camera module or a telephoto camera module to cooperate with the imaging of the camera module 1 and the first sub-module 102. For example, the second sub-module 103 can be a telephoto camera module with a focal length smaller than that of the camera module 1, thereby making the zoom of the array module 100 smoother.

[0374] It should be understood that in this embodiment, the optical axis of the second lens 1032 of the second sub-module 103 can be parallel to the optical axis of the optical lens 10 of the camera module 1 and the optical axis of the first lens 1022 of the first sub-module 102 .

[0375] It should be understood that in the present application, the array module 100 may further include more modules, and the present application merely exemplarily points out the arrangement of two and three modules.

[0376] Figures 17 to 23B show a camera module 1' according to some embodiments of the present application. The camera module 1' includes an optical lens 10', a light deflecting element 30', a photosensitive component 40', and a driving device 60'. The light deflecting element 30' is disposed between the optical lens 10' and the photosensitive component 40', so that the light incident on the optical lens 10' is reflected at least once in the light deflecting element 30' before reaching the photosensitive component 40'. The light deflecting element 30' folds the light emitted from the optical lens 10' and guides it to the photosensitive component 40', thereby imaging through the photosensitive component 40' to obtain image information. It is worth mentioning that the light deflecting element 30' is in the shape of an elongated strip, so that the light can be reflected multiple times in the light deflecting element 30', thereby folding the light path multiple times. In the present application, the position of one or more components in the optical lens 10', the light deflection element 30' or the photosensitive component 40' in the camera module 1' can be adjusted to achieve the optical focus and / or optical image stabilization function of the camera module 1'. For example, the driving device 60' can be configured to drive one or more components in the optical lens 10', the light deflection element 30' or the photosensitive component 40' to move.

[0377] The optical lens 10' has an optical axis. Light incident on the light deflection element 30' along the optical axis is reflected at least once within the light deflection element 30', that is, the light is deflected from propagating along the optical axis to propagating in another direction approximately orthogonal to the optical axis, and finally emitted along the optical axis to reach the photosensitive component 40'. For ease of description, a rectangular coordinate system is established, with the Z axis approaching the optical axis of the optical lens 10' or parallel to the optical axis of the optical lens 10'. The Z axis is perpendicular to the plane containing the X and Y axes. The X and Y axes are mutually perpendicular. The XOY plane containing the X and Y axes is also referred to as the horizontal plane. The horizontal direction is the direction perpendicular to the optical axis of the optical lens 10'. That is, the X axis is the length direction of the camera module 1', the Y axis is the width direction of the camera module 1', and the Z axis is the height direction of the camera module 1'. It should be understood that in the embodiments of the present application, the optical axis of the optical lens 10' is also referred to as the optical axis of the camera module 1'.

[0378] As shown in Figures 20A to 20B, the light deflecting element 30' includes multiple reflective surfaces. The light emitted by the optical lens 10' is reflected multiple times on the multiple reflective surfaces of the light deflecting element 30'. After being emitted by the light deflecting element 30', the light reaches the photosensitive component 40'. The photosensitive component 40' and the optical lens 10' are arranged on the same side of the light deflecting element 30'. Therefore, the height dimension of the camera module 1' only needs to consider the sum of the height dimension of one of the photosensitive component 40' and the optical lens 10' and the height dimension of the light deflecting element 30', without having to simultaneously superimpose the heights of the optical lens 10', the light deflecting element 30' and the photosensitive component 40'. In this way, the height dimension of the camera module 1' can be reduced. In a specific example, the optical lens 10' and the light deflecting element 30' form an "L"-shaped structure, and the photosensitive component 40' is arranged in the corner space formed by the optical lens 10' and the light deflecting element 30'. The height dimension of the optical lens 10' is greater than the height dimension of the photosensitive component 40', and the top surface of the optical lens 10' is higher than the top surface of the photosensitive component 40'. In this way, the photosensitive component 40' does not affect the height of the camera module 1', wherein the top surface of the optical lens 10' and the top surface of the photosensitive component 40' respectively refer to the side thereof away from the light deflecting element 30'. In the present application, the optical lens 10' and the light deflecting element 30' together constitute the optical component of the camera module 1' described in this application. In other words, the optical component includes the optical lens 10' and the light deflecting element 30'.

[0379] The optical lens 10' includes a lens barrel 12' and at least one optical lens 11' housed in the lens barrel 12'. The optical lens 10' collects light from the subject and transmits it to the light deflection element 30'. The optical lens 10' has an optical axis that is perpendicular to the light deflection element 30'. In a specific example, as shown in Figures 20A and 20B, the optical lens 10' includes three optical lenses 11': a first lens L1', a second lens L2', and a third lens L3', arranged along the incident direction of the light. The first lens L1', the second lens L2', and the third lens L3' are fixed to the lens barrel 12', thereby maintaining the spacing between the three optical lenses 11'.

[0380] In one embodiment of the present application, the camera module 1' further includes a compensation lens group 20', which can be disposed between the light deflecting element 30' and the photosensitive component 40'. The compensation lens group 20' can further modulate the light emitted from the light deflecting element 30'. For example, the compensation lens group 20' can further converge the light emitted from the light deflecting element 30' to reduce the back focus, thereby achieving the purpose of reducing the size of the camera module 1'. In a specific example, as shown in FIG20B , the compensation lens group 20' includes a compensation lens 21', which is disposed between the light deflecting element 30' and the photosensitive component 40'. For example, the compensation lens 21' can be fixed to the light deflecting element 30' by gluing.

[0381] Continuing with Figures 17 to 23B , the photosensitive assembly 40' includes a chip circuit board 42', a photosensitive chip 41' electrically connected to the chip circuit board 42', and at least one electronic component. The photosensitive surface of the photosensitive chip 41' faces the light deflecting element 30' to receive light emitted from the light deflecting element 30'. In one specific example, the photosensitive chip 41' is affixed to the side of the chip circuit board 42' facing the light deflecting element 30'. The at least one electronic component can be implemented as a passive electronic device such as a capacitor or resistor, or an active electronic device such as a diode or memory chip. The at least one electronic component can be disposed on the side of the chip circuit board 42' facing the light deflecting element 30' or on the other side away from the light deflecting element 30'. It should be understood that the photosensitive assembly 40' and the optical lens 10' being disposed on the same side of the light deflecting element 30' means that the photosensitive chip 41' and the optical lens 10' in the photosensitive assembly 40' are disposed on the same side of the light deflecting element 30'. Thus, in a specific example, the direction in which the light enters the optical lens 10 ′ is opposite to the direction in which the light enters the photosensitive chip 41 ′ of the photosensitive component 40 ′.

[0382] Furthermore, in some embodiments of the present application, the camera module 1' further includes a filter assembly 50', which is disposed on the optical path of the light, and the camera module 1' can filter out unnecessary stray light (such as infrared rays) through the filter assembly 50'. In one embodiment of the present application, the filter assembly 50' is disposed between the light deflection element 30' and the photosensitive assembly 40'. For example, in a specific example, the filter assembly 50' includes a filter element 51' and a filter element bracket 52' for supporting the filter element 51'. The filter element 51' is supported on the filter element bracket 52' by, for example, gluing. Both sides of the filter element bracket 52' are respectively fixed to the chip circuit board 42', so that the filter assembly 50' is disposed between the light deflection element 30' and the photosensitive chip 41'. In other embodiments of the present application, the filter component 50' can be arranged in the light deflecting element 30' and / or the optical lens 10'. For example, the filter component 50' can be implemented as a layer of filter film, which is attached to a surface of the light deflecting element 30', or the filter film is attached to the surface of at least one optical lens 11' of the optical lens 10', thereby achieving the function of filtering out infrared light.

[0383] In the present application, as shown in Figures 20A and 30B , the light deflecting element 30' has multiple reflective surfaces, allowing light entering the light deflecting element 30' to undergo multiple reflections. This effectively increases the optical TTL, making the camera module 1' suitable for capturing distant objects and providing high-quality images of these distant objects. TTL refers to the distance on the optical axis between the front vertex of the light-entering side (facing the subject) of the optical lens 10' of the camera module 1' and the image plane at the photosensitive component 40'.

[0384] Under normal circumstances, an increase in TTL increases the size of the camera module, making it unsuitable for integration into small mobile devices. In one embodiment of the present application, the light deflection element 30' extends horizontally, that is, the length of the light deflection element 30' in the horizontal direction is greater than its height or thickness in the vertical direction. When light is reflected multiple times within the light deflection element 30', the light deflection element 30' can maintain a lower height or thickness, thereby avoiding an increase in the height of the camera module. In other words, the length of the light deflection element 30' extending in the horizontal direction is greater than its height extending in the vertical direction, so as to reduce the height of the camera module while maintaining its effectiveness, thereby meeting the demand for miniaturization of the camera module.

[0385] In one embodiment of the present application, the number of times light is reflected in the light deflecting element 30' is an odd number, and the photosensitive component 40' and the optical lens 10' are centrally arranged on the same side of the light deflecting element 30'. Light passing through the optical lens 10' is reflected an odd number of times in the light deflecting element 30' before being emitted to the photosensitive component 40'. In another embodiment of the present application, the number of times light is reflected in the light deflecting element 30' is an even number, and the photosensitive component 40' and the optical lens 10' are arranged on opposite sides of the light deflecting element 30'. Light passing through the optical lens 10' is reflected an even number of times in the light deflecting element 30' before being emitted to the photosensitive component 40'.

[0386] Specifically, in one embodiment of the present application, the light deflecting element 30' includes at least four surfaces, at least three of the at least four surfaces are reflective surfaces, and the light is reflected on the at least three reflective surfaces in the light deflecting element 30'. For example, the light deflecting element 30' includes a trapezoidal prism, and the cross-section of the light deflecting element 30' is a trapezoid. When the light deflecting element 30' includes three reflective surfaces, the light is reflected three times in the light deflecting element 30'; when the light deflecting element 30' includes four reflective surfaces, the light is reflected five times or four times in the light deflecting element 30', which will be described in detail later in this application. Of course, in other embodiments of the present application, the light deflecting element 30' may include prisms of other shapes, such as triangular prisms, pentagonal prisms, hexagonal prisms, etc., and still provide the above-mentioned light deflection function and design benefits, and this application does not limit this.

[0387] As shown in Figures 20A and 20B, in one embodiment of the present application, the light deflecting element 30' is implemented as a trapezoidal prism. The light deflecting element 30' includes four surfaces, for example, a first surface 31', a second surface 32', a third surface 33', and a fourth surface 34'. The planes of the first surface 31' and the third surface 33' are parallel to each other, the length of the third surface 33' is less than that of the first surface 31', and the planes of the second surface 32' and the fourth surface 34' intersect. At least three of the four surfaces of the light deflecting element 30' have a reflective function. For example, the first surface 31', the second surface 32', the third surface 33', and the fourth surface 34' are reflective surfaces that reflect light, thereby achieving four, five, or more reflections of light within the light deflecting element 30'. Alternatively, only the first surface 31', the second surface 32', and the fourth surface 34' may be reflective surfaces that reflect light, thereby achieving only three reflections of light within the light deflecting element 30'.

[0388] In a specific example, the angle at which the second surface 32' intersects the first surface 31' is an acute angle, the angle at which the fourth surface 34' intersects the first surface 31' is an acute angle, the angle at which the second surface 32' intersects the third surface 33' is an obtuse angle, and the angle at which the fourth surface 34' intersects the third surface 33' is an obtuse angle. Among them, the angle at which the second surface 32' intersects the first surface 31' may be in the range of 25° and 35°, and the angle at which the fourth surface 34' intersects the first surface 31' may be in the range of 25° and 35°. It should be understood that the angles between the various surfaces of the light deflection element 30' can control the reflection angle of light when it is reflected in the light deflection element 30', so as to realize the function of the light deflection element 30' to reflect light multiple times.

[0389] Furthermore, the light deflection element 30' is an isosceles trapezoidal prism, that is, the cross-section of the light deflection element 30' in the height direction is an isosceles trapezoid (similar to an isosceles trapezoid). As shown in the cross-sectional view of the trapezoidal prism (see Figures 20A and 20B), the second surface 32' and the fourth surface 34' are equal in length, and the second surface 32' and the fourth surface 34' are axially symmetrical. The angle between the second surface 32' and the first surface 31' is equal to the angle between the fourth surface 34' and the first surface 31', and the angle between the second surface 32' and the third surface 33' is equal to the angle between the fourth surface 34' and the third surface 33'. In a specific example, the optical path of the optical axis of the incident light in the light deflection element 30' is axially symmetrical.

[0390] In one embodiment of the present application, the second surface 32', the fourth surface 34' and / or the third surface 33' of the light deflecting element 30' may be provided with a reflective coating, or a reflector may be provided, so that light can be reflected on the second surface 32', the fourth surface 34' and / or the third surface 33'. For example, in a specific example of the present application, the reflective coating may include a mirror coating based on a thin metal layer, a film with a white inner surface, etc. Further, at least a portion of the first surface 31' of the light deflecting element 30' is provided with a reflective coating, and at least a portion of the first surface 31' is not provided with a reflective coating, so that the first surface 31' can transmit light or allow light to pass through the first surface 31'. Further, the first surface 31' can also reflect light under the phenomenon of total internal reflection.

[0391] It should be understood that total internal reflection can occur when the incident angle of light approaches or exceeds a certain limiting angle (called the critical angle). The incident angle refers to the angle between the light incident on a surface and a line perpendicular to the surface at the point of incidence (called the normal). Therefore, when the incident angle of light is less than the critical angle, the first surface 31' of the light deflecting element 30' allows the light to pass through; when the incident angle of light approaches or exceeds the critical angle, the first surface 31' of the light deflecting element 30' reflects the light at the corresponding surface.

[0392] Specifically, in one embodiment of the present application, the first surface 31' includes a light entrance area 311', a light exit area 312', and a reflective area 313' disposed between the light entrance area 311' and the light exit area 312'. The light entrance area 311' and the light exit area 312' are not provided with a reflective coating, so that light can enter the light deflecting element 30' from the light entrance area 311' and exit the light deflecting element 30' from the light exit area 312'. The reflective area 313' is provided with a reflective coating so that light is reflected when passing through the reflective area 313'.

[0393] In one example, the size of the light entrance area 311' is equal to the size of the light exit area 312', and the size of the reflection area 313' is not less than the size of the light entrance area 311' or the light exit area 312', so that light entering the light deflection element 30' from the light entrance area 311' can be reflected and then emitted from the light exit area 312' to reach the photosensitive component 40', thereby avoiding light loss and reducing the generation of stray light. In a specific example of the present application, the size of the light entrance area 311' is equal to the size of the reflection area 313' and the size of the light exit area 312', so that the multiple reflection effect of the light deflection element 30' is better, thereby avoiding light loss and reducing the generation of stray light.

[0394] Furthermore, both the light entrance area 311' and the light exit area 312' are located on the first surface 31'. This means that light from the camera module 1' enters and exits the camera module 1' on the same side of the light deflection element 30'. This way, the optical lens 10' and the photosensitive component 40' are concentrated on the same side of the light deflection element 30'. Consequently, the height of the camera module 1' is determined solely by the sum of the height of the optical lens 10' or the photosensitive component 40' and the height of the light deflection element 30', thus reducing the height of the camera module 1'.

[0395] In one embodiment of the present application, the light deflecting element 30' can reflect the light within the light deflecting element 30' an odd number of times to guide the light from the optical lens 10' through the light deflecting element 30' to the photosensitive component 40'. When the light is reflected three times within the light deflecting element 30', the light passes through the light entrance area 311' of the first surface 31' and enters the light deflecting element 30'; at least some of the light passing through the light entrance area 311' of the first surface 31' is reflected at the second surface 32'; at least some of the light reflected from the second surface 32' is reflected at the reflection area 313' of the first surface 31'; and at least some of the light reflected from the reflection area 313' of the first surface 31' is reflected at the fourth surface 34', so that the light passes through the light exit area 312' of the first surface 31' and reaches the photosensitive component 40'.

[0396] In another embodiment of the present application, as shown in Figure 20A, when the light is reflected five times in the light deflecting element 30', the light passes through the light entrance area 311' of the first surface 31' and enters the light deflecting element 30'; at least some of the light passing through the light entrance area 311' of the first surface 31' is reflected at the second surface 32'; at least some of the light reflected from the second surface 32' is reflected at the reflection area 313' of the first surface 31'; at least some of the light reflected from the reflection area 313' of the first surface 31' is reflected at the third surface 33'; at least some of the light reflected from the third surface 33' is reflected at the light exit area 312' of the first surface 31'; and, at least some of the light reflected from the light exit area 312' of the first surface 31' is reflected at the fourth surface 34', so that the light passes through the light exit area 312' of the first surface 31' and reaches the photosensitive component 40'.

[0397] It should be understood that light from the optical lens 10' may pass through the light entrance area 311' of the first surface 31' and enter the light deflecting element 30', where it undergoes an odd number of reflections. At least some of the light may then reach the second surface 32' and be reflected there. At least some of the light reflected from the second surface 32' may then reach the reflection area 313' or the light entrance area 311' of the first surface 31'. When light reaches the reflection area 313' of the first surface 31', it is reflected at the reflection area 313' of the first surface 31', and at least some of the light reflected from the reflection area 313' of the first surface 31' can reach the third surface 33' or the fourth surface 34', and be reflected at the third surface 33' or the fourth surface 34'; when light reaches the light entrance area 311' of the first surface 31', when the incident angle of the light is close to or greater than the critical angle of the light turning element 30', the light can be reflected at the light entrance area 311' of the first surface 31' under total internal reflection, and at least some of the light reflected from the light entrance area 311' of the first surface 31' can reach the third surface 33' or the fourth surface 34', and be reflected at the third surface 33' or the fourth surface 34'.

[0398] If at least some of the light reflected from the first surface 31' reaches the fourth surface 34' and is finally reflected at the fourth surface 34', it leaves the light deflecting element 30' and reaches the photosensitive component 40'. In one embodiment, the light is reflected three times in the light deflecting element 30', which effectively increases the focal length between the optical lens 10' and the photosensitive component 40'. In other words, the optical TTL of the camera module 1' can be effectively increased, making the camera module 1' suitable for capturing objects at a distance and providing high-quality images of the distant objects.

[0399] If at least some of the light reflected from the first surface 31' reaches the third surface 33', then at least some of the light reflected from the third surface 33' may reach the light exit area 312' of the first surface 31'. When the incident angle of the light is close to or greater than the critical angle of the light deflection element 30', the light may be reflected at the light exit area 312' of the first surface 31' under total internal reflection. At least some of the light reflected from the light exit area 312' of the first surface 31' may reach the fourth surface 34' and finally be reflected at the fourth surface 34', leaving the light deflection element 30' to reach the photosensitive component 40'. As shown in FIG20A , in this embodiment, the light is reflected five times in the light deflection element 30', which can effectively increase the focal length between the optical lens 10' and the photosensitive component 40'. That is, the optical TTL of the camera module 1' can be effectively increased, making the camera module 1' suitable for capturing objects at a long distance and providing high-quality images of the distant objects.

[0400] In another embodiment of the present application, the light deflecting element 30' is implemented as a parallelogram prism, and the light deflecting element 30' includes four surfaces, for example: a first surface 31', a second surface 32', a third surface 33', and a fourth surface 34'. The plane where the first surface 31' is located is parallel to the plane where the third surface 33' is located, and the plane where the second surface 32' is located is parallel to the plane where the fourth surface 34' is located. The four surfaces of the light deflecting element 30' have a reflective function, for example: the first surface 31', the second surface 32', the third surface 33', and the fourth surface 34' are reflective surfaces that can reflect light.

[0401] In this embodiment, light is reflected four times by the light deflecting element 30'. The photosensitive component 40' and the optical lens 10' are positioned on opposite sides of the light deflecting element 30'. Light passing through the optical lens 10' reflects four times within the light deflecting element 30' before exiting and reaching the photosensitive component 40'. For example, the optical lens 10' is positioned on one side of the first surface 31', and the photosensitive component 40' is positioned on one side of the third surface 33'.

[0402] In one embodiment of the present application, the light deflection element 30' can be implemented as an integrated prism, as shown in FIG20A and FIG20B , and the integrated prism is a trapezoidal prism. In another embodiment of the present application, the light deflection element 30' can also be implemented as a split prism, that is, the light deflection element 30' can be formed by combining multiple prisms. For example, the split prism includes at least two prisms: a first prism and a second prism, wherein, in a specific example of the present application, the first prism is a parallelogram prism, and the second prism is a triangular prism, and the first prism and the second prism are joined together by an optically transparent adhesive or a snap fastener to form the light deflection element 30'. In this way, when the light deflection element 30' is manufactured by a paneling method, the manufacturing process can be simplified and the utilization rate of raw materials can be improved. Of course, it should be understood that in another specific example of the present application, the first prism can be a right-angled trapezoidal prism, the second prism can be a right-angled triangular prism or a right-angled trapezoidal prism, and the first prism and the second prism are joined together by optically transparent adhesive or snap fasteners to form a light turning element 30'.

[0403] In another specific example of the present application, as shown in Figure 21A, the split prism 36' also includes a third prism 363', wherein the first prism 361' is a right-angled trapezoidal prism, the second prism 362' is a rectangular prism, and the third prism 363' is a right-angled trapezoidal prism. The first prism 361', the second prism 362' and the third prism 363' are joined together by optically transparent adhesives or snaps to form a light deflection element 30'. In this way, when the light deflection element 30' is manufactured by paneling, the manufacturing process can be simplified and the utilization rate of raw materials can be improved. Alternatively, as shown in Figure 21B, the first prism 361' and the third prism 363' are triangular prisms, and the second prism 362' is a quadrilateral prism. For example, the first prism 361' and the third prism 363' are right-angled triangular prisms, and the second prism 362' is a rectangular prism; or, the first prism 361' and the third prism 363' are triangular prisms, and the second prism 362' is a parallelogram prism. The first prism 361', the second prism 362' and the third prism 363' are joined together by optically transparent adhesives or snaps to form a light turning element 30'.

[0404] Continuing with reference to Figure 21A, in the split prism 36', the second prism 362' is arranged between the first prism 361' and the third prism 363'. When light passes through the light entrance area 311' of the first prism 361' and enters the first prism 361', at least some of the light is reflected at least once in the first prism 361' and reaches the second prism 362'. Then, at least some of the light reaching the second prism 362' is reflected at least once in the second prism 362' and reaches the third prism 363'. Finally, at least some of the light reaching the third prism 363' is reflected at least once in the third prism 363' and reaches the light exit area 312' of the third prism 363', and is emitted from the third prism 363' to reach the photosensitive component 40'.

[0405] It should be understood that in the present application, the light entrance area 311' of the first prism 361' and the light exit area 312' of the third prism 363' are both arranged on the same side of the light deflection element 30' (split prism 36') so that light can enter and exit from the same side of the light deflection element 30'. In this way, the optical lens 10' and the photosensitive component 40' can be concentrated on the same side of the light deflection element 30' to reduce the height of the camera module 1'.

[0406] Furthermore, the light deflection element 30' may also include a shading film disposed between the first prism 361' and the second prism 362' and / or disposed between the second prism 362' and the third prism 363'. Specifically, as shown in FIG21A and FIG21B , a U-shaped shading film is provided on the side of the second prism 362' facing the first prism 361', and a U-shaped shading film is provided on the side of the second prism 362' facing the third prism 363'. It is understandable that the shading film may also be provided on the side of the first prism 361' or the third prism 363' facing the second prism 362'. By providing the shading film, the influence of stray light on imaging can be reduced, and the problem of glare can be reduced.

[0407] It should be understood that the split prism 36' may also include other numbers of prisms, such as four prisms, five prisms, or six prisms, and this application is not limited thereto. Of course, in other embodiments of this application, the light deflection element 30' may also be implemented as multiple reflectors, with multiple reflectors disposed at locations where light needs to be reflected to form the light deflection element 30'.

[0408] As shown in Figures 17, 18A, 18B, 19A, 19B, 22, 23A and 23B, in one example, the driving device 60' is implemented as a chip driving component for driving the photosensitive component 40' to move. Among them, Figure 17 shows a three-dimensional schematic diagram of the camera module 1'; Figure 18A shows a cross-sectional view of the camera module 1' along the length direction (i.e., the X-axis direction defined above); Figure 18B further shows an enlarged schematic diagram of the circular area in Figure 18A; Figure 19A shows a cross-sectional view of the camera module 1' along the width direction (i.e., the Y-axis direction defined above); Figure 19B further shows an enlarged schematic diagram of the circular area in Figure 3A; Figure 22 shows an exploded schematic diagram of the driving device 60', from which the implementation method of the focusing function of the camera module 1' can be learned; Figures 23A and 23B show exploded schematic diagrams of the partial structure of the driving device 60' from two perspectives, one from top and one from bottom, respectively, from which the implementation method of the anti-shake function can be learned. The camera module 1' comprises a driving device 60' and an optical lens 10', a light deflection element 30', a filter assembly 50' and a photosensitive assembly 40' arranged in the driving device 60', wherein the photosensitive assembly 40' is arranged on the light-emitting side of the light deflection element 30', and the optical lens 10' is arranged on the light-incident side of the light deflection element 30'. The light emitted by the optical lens 10' is reflected multiple times on multiple reflective surfaces of the light deflection element 30' and then emitted from the light deflection element 30' and reaches The photosensitive component 40' and the light deflection element 30' are fixed to the fixed part of the driving device 60', the photosensitive component 40' is fixed to the movable part of the driving device 60', the optical lens 10' is directly or indirectly fixed to the light deflection element 30', the filter component 50' is directly or indirectly fixed to the photosensitive component 40', and the driving device 60' can drive the photosensitive component 40' to move relative to the light deflection element 30', thereby changing the optical performance of the camera module 1' by moving the chip.

[0409] Continuing to refer to Figures 17, 18A, 18B, 19A, 19B, 22, 23A and 23B, the driving device 60' includes a frame 64', a movable carrier 67' and an anti-shake driving unit 66'. The anti-shake driving unit 66' connects the frame 64' and the movable carrier 67' and drives the movable carrier 67' to move in the horizontal direction relative to the frame 64'. Specifically, the movable carrier 67' is movably disposed in the frame 64', and the anti-shake driving unit 66' is disposed between the frame 64' and the movable carrier 67', so that the movable carrier 67' is driven by the anti-shake driving unit 66' to move in the horizontal direction relative to the frame 64'. The driving device 60' is configured to drive the photosensitive component 40' to move. The photosensitive component 40' is movably arranged at one end of the driving device 60' away from the optical lens 10'. Specifically, the driving device 60' is configured to drive the photosensitive chip 41' of the photosensitive component 40' to move.

[0410] It should be understood that the anti-shake drive unit 66' being disposed between the frame 64' and the movable carrier 67' includes not only the case where the anti-shake drive unit 66' is disposed between the side of the frame 64' facing the movable carrier 67' and the side of the movable carrier 67' facing the frame 64', but also the case where the anti-shake drive unit 66' is disposed between the outer side of the frame 64' away from the movable carrier 67' and the outer side of the movable carrier 67' away from the frame 64'. In other words, in the present application, at least a portion of the anti-shake drive unit 66' being located between the frame 64' and the movable carrier 67' is considered to be disposed between the frame 64' and the movable carrier 67'. In this way, the frame 64' or the movable carrier 67' may be provided with a groove or through-hole to accommodate a portion of the anti-shake drive unit 66'.

[0411] Specifically, as shown in Figures 18A, 18B, 19A, and 19B, the photosensitive component 40' is fixed to the movable carrier 67' in a direction facing the light deflection element 30', so that the photosensitive component 40' moves with the movable carrier 67' to achieve the chip anti-shake function. In other words, in a specific example, the photosensitive component 40' is fixed above the movable carrier 67'. It should be understood that in this application, the direction in which the photosensitive component 40' faces the light deflection element 30' refers to the direction in which the photosensitive chip 41' of the photosensitive component 40' faces the light deflection element 30'. The photosensitive chip 41' of the photosensitive component 40' faces the light deflection element 30' to receive the light emitted by the light deflection element 30'. In other words, compared to a conventional upright module, the photosensitive component 40' is fixed to the movable carrier 67' in an inverted state. The side of the chip circuit board 42' of the photosensitive assembly 40' that faces the light deflection element 30' is defined as the front side of the chip circuit board 42'. In one specific example, the movable carrier 67' is fixed to the front side of the chip circuit board 42', and the chip circuit board 42' is fixed above the movable carrier 67'. It is worth noting that the movable carrier 67' can be directly fixed to the chip circuit board 42' using glue, or it can be indirectly fixed to the chip circuit board 42' by being fixed to the filter element bracket 52' of the filter assembly 50'.

[0412] There is an air gap between the movable carrier 67' and the light deflection element 30', and between the movable carrier 67' and the frame 64', respectively, so that the anti-shake driving unit 66' can drive the movable carrier 67' to move in the horizontal direction (i.e., the direction perpendicular to the optical axis of the optical lens 10') relative to the frame 64' and the light deflection element 30', thereby realizing the chip anti-shake function. It should be understood that in the present application, the horizontal part of the air gap formed between the movable carrier 67' and the light deflection element 30', and between the movable carrier 67' and the frame 64' is suitable for being adjusted in the realization of the chip anti-shake function. In a specific example, the movable carrier 67' is in the shape of a "Π" and is arranged around the light deflection element 30'.

[0413] The frame 64' is arranged on the outside of the movable carrier 67', and the anti-shake drive unit 66' is arranged between the movable carrier 67' and the frame 64'. The anti-shake drive unit 66' includes at least one anti-shake magnet 661' and at least one anti-shake coil 662'. The at least one anti-shake magnet 661' is directly or indirectly fixed to one of the movable carrier 67' and the frame 64', and the at least one anti-shake coil 662' is directly or indirectly fixed to the other of the movable carrier 67' and the frame 64'. The at least one anti-shake magnet 661' and the at least one anti-shake coil 662' are arranged opposite to each other, so that the movable carrier 67' can be driven to move relative to the frame 64' by the magnetic force between the at least one anti-shake magnet 661' and the at least one anti-shake coil 662' to realize the chip anti-shake function.

[0414] In one specific example, at least one anti-shake magnet 661' is disposed on the frame 64', and at least one anti-shake coil 662' is disposed on the movable carrier 67'. The at least one anti-shake magnet 661' includes a first anti-shake magnet 6611' and a second anti-shake magnet 6612', and the at least one anti-shake coil 662' includes a first anti-shake coil 6621' and a second anti-shake coil 6622'. In other words, the anti-shake drive unit 66' includes a first anti-shake magnet 6611' and a second anti-shake magnet 6612' fixed to the frame 64', and a first anti-shake coil 6621' and a second anti-shake coil 6622' fixed to the movable carrier 67'. The first anti-shake magnet 6611' and the second anti-shake magnet 6612' are disposed on two adjacent sides of the top surface of the frame 64', and the first anti-shake coil 6621' and the second anti-shake coil 6622' are disposed on two adjacent sides of the movable carrier 67'. The first anti-shake coil 6621' and the first anti-shake magnet 6611' are arranged relative to each other so that, when energized, the first anti-shake coil 6621' generates a magnetic field, which interacts with the first anti-shake magnet 6611', thereby driving the movable carrier 67' to move relative to the frame 64' in a first horizontal direction. The second anti-shake coil 6622' and the second anti-shake magnet 6612' are arranged relative to each other so that, when energized, the second anti-shake coil 6622' generates a magnetic field, which interacts with the second anti-shake magnet 6612', thereby driving the movable carrier 67' to move relative to the frame 64' in a second horizontal direction. That is, in this example, in implementing chip anti-shake, at least one anti-shake coil 662' (the first anti-shake coil 6621' and the second anti-shake coil 6622') serves as a mover, and at least one anti-shake magnet 661' (the first anti-shake magnet 6611' and the second anti-shake magnet 6612') serves as a stator.

[0415] In one example, the first anti-shake magnet 6611' and the second anti-shake magnet 6612' are arranged on two adjacent sides perpendicular to each other on the top surface of the frame 64', and the first anti-shake coil 6621' and the second anti-shake coil 6622' are arranged on two adjacent sides perpendicular to each other on the movable carrier 67'. The first horizontal direction is perpendicular to the second horizontal direction. For example, the first horizontal direction can be the Y-axis direction, and the second horizontal direction can be the X-axis direction.

[0416] In other words, the first anti-shake coil 6621' and the first anti-shake magnet 6611' are arranged relative to each other in the height direction, and the second anti-shake coil 6622' and the second anti-shake magnet 6612' are arranged relative to each other in the height direction. That is, in this specific example, the anti-shake drive unit 66' includes at least one anti-shake magnet 661' and at least one anti-shake coil 662' arranged relative to each other in the height direction, and this height direction is parallel to the optical axis of the optical lens 10'. In this way, the relative area between the first anti-shake magnet 6611' and the first anti-shake coil 6621' can be increased, and the relative area between the second anti-shake magnet 6612' and the second anti-shake coil 6622' can be increased, while maintaining a smaller height dimension, thereby providing a greater horizontal driving force. Specifically, at least one anti-shake coil 662' is positioned above at least one anti-shake magnet 661', allowing the at least one anti-shake coil 662' to be positioned on the movable carrier 67'. The photosensitive component 40' is also secured to the movable carrier 67', facilitating electrical connection between the at least one anti-shake coil 662' and the photosensitive component 40'. In one specific example, a first anti-shake coil 6621' and a second anti-shake coil 6622' are secured to opposite sides of the chip circuit board 42' and electrically connected to the chip circuit board 42'. Openings are formed on the movable carrier 67' at locations corresponding to the first and second anti-shake coils 6621', 6622', respectively, to accommodate the first and second anti-shake coils 6621', 6622', respectively, so that the first anti-shake coil 6621' and the first anti-shake magnet 6611' are positioned directly face-to-face, and the second anti-shake coil 6622' and the second anti-shake magnet 6612' are positioned directly face-to-face. In this specific example, at least one anti-shake coil 662' (a first anti-shake coil 6621' and a second anti-shake coil 6622') is indirectly fixed to the movable carrier 67' by being fixed to a chip circuit board 42' fixed to the movable carrier 67'. In this way, at least one anti-shake magnet 661' drives at least one anti-shake coil 662' and the chip circuit board 42' directly or indirectly fixed to the anti-shake coil 662' and the movable carrier 67' to move in the horizontal direction.

[0417] It is worth mentioning that the movable carrier 67' can be driven to move horizontally relative to the frame 64' by the magnetic force between the first anti-shake coil 6621' and the first anti-shake magnet 6611' and the magnetic force between the second anti-shake coil 6622' and the second anti-shake magnet 6612' at the same time, or the movable carrier 67' can be driven to move horizontally relative to the frame 64' only by the magnetic force between the first anti-shake coil 6621' and the first anti-shake magnet 6611' or the magnetic force between the second anti-shake coil 6622' and the second anti-shake magnet 6612'.

[0418] Specifically, the frame 64' has an opening facing the side of the light deflecting element 30', and the frame 64' includes an integrally formed first frame portion 643', a second frame portion 644' and a frame connecting portion 645', wherein the first frame portion 643' and the second frame portion 644' are respectively connected to the two ends of the frame connecting portion 645' and are respectively perpendicular to the frame connecting portion 645', so that the frame 64' is in a "Π" shape to avoid the position of the light deflecting element 30' and reduce the size of the driving device 60'. The frame 64' is arranged around three sides of the light deflecting element 30'. The first anti-shake magnet 6611' is mounted on the top surface of the first frame portion 643'. The top surface of the first frame portion 643' has a groove to accommodate the first anti-shake magnet 6611'. The second anti-shake magnet 6612' is mounted on the top surface of the frame connection portion 645'. The top surface of the frame connection portion 645' also has a groove to accommodate the second anti-shake magnet 6612'. In this way, the size of the drive device 60' and the camera module 1' can be reduced. In other words, the first anti-shake magnet 6611' and the second anti-shake magnet 6612' are mounted on two adjacent side edges of the top surface of the frame 64'. It should be understood that the "Π" shape of the frame 64' can be obtained when looking down at the frame 64' from the height direction.

[0419] Accordingly, the movable carrier 67' has an opening facing one side of the light deflecting element 30'. The movable carrier 67' comprises an integrally formed first carrier portion 671', a second carrier portion 672', and a carrier connecting portion 673'. The first carrier portion 671' and the second carrier portion 672' are respectively connected to the ends of the carrier connecting portion 673' and are perpendicular to the carrier connecting portion 673', forming a "Π" shape. This avoids the position of the light deflecting element 30' and reduces the size of the drive device 60'. The movable carrier 67' is arranged around three sides of the light deflecting element 30'. An opening is formed on the first carrier portion 671' at a position corresponding to the first anti-shake coil 6621' to accommodate the first anti-shake coil 6621'. An opening is also formed on the carrier connecting portion 673' at a position corresponding to the second anti-shake coil 6622' to accommodate the second anti-shake coil. In other words, the first anti-shake coil 6621' and the second anti-shake coil 6622' are arranged on two adjacent sides of the movable carrier 67'. It should be understood that the “Π” shape of the movable carrier 67 ′ can also be obtained when the movable carrier 67 ′ is viewed from above from a height direction.

[0420] It is worth mentioning that, as shown in Figures 18A, 18B and 19A, the anti-shake drive unit 66' extends downward from the chip circuit board 42' in the height direction, and the bottom surface of the anti-shake drive unit 66' is lower than the top surface of the light turning element 30' but higher than the bottom surface of the light turning element 30'. The anti-shake drive unit 66' is arranged on the side of the light turning element 30', so that the height of the driving device 60' and the camera module 1' is not increased due to the setting of the anti-shake drive unit 66'. Specifically, the first anti-shake coil 6621' and the first anti-shake magnet 6611' extend downward from the chip circuit board 42' along the height direction, and the bottom surface of the first anti-shake magnet 6611' is lower than the top surface of the light turning element 30' but higher than the bottom surface of the light turning element 30'. The second anti-shake coil 6622' and the second anti-shake magnet 6612' extend downward from the chip circuit board 42' along the height direction, and the bottom surface of the second anti-shake magnet 6612' is lower than the top surface of the light turning element 30' but higher than the bottom surface of the light turning element 30'. The first anti-shake magnet 6611' and the second anti-shake magnet 6612' are arranged on the side of the light turning element 30'.

[0421] In this embodiment, the driving device 60' further includes an anti-shake support portion 68' and an anti-shake magnetic component 69'. As shown in Figures 23A and 23B, the anti-shake support portion 68' is arranged between the frame 64' and the movable carrier 67' to maintain an air gap between the frame 64' and the movable carrier 67', thereby reducing the resistance encountered by the movable carrier 67' when moving relative to the frame 64'. In a specific example, the anti-shake support portion 68' can be implemented as a ball 681', and the anti-shake support portion 68' includes at least three balls 681', and the at least three balls 681' are arranged between the movable carrier 67' and the frame 64' along the height direction and support the movable carrier 67' and the frame 64', so that a fixed air gap is maintained between the movable carrier 67' and the frame 64' in the height direction. It should be understood that the ball bearings 681' can roll between the movable carrier 67' and the frame 64', or can interact between the movable carrier 67' and the frame 64'. For example, the ball bearings 681' can be fixed to the movable carrier 67' or the frame 64' by insert molding or bonding. It should be understood that the anti-shake support portion 68' can also be implemented as other components such as a spring or a slider.

[0422] The anti-shake magnetic component 69' is made of a material suitable for being attracted by magnets. The anti-shake magnetic component 69' is directly or indirectly fixed to the movable carrier 67' and corresponds to at least one anti-shake magnet 661'. The anti-shake magnetic component 69' is arranged above the at least one anti-shake magnet 661', so that the movable carrier 67' is adsorbed toward the frame 64' through the magnetic force between the anti-shake magnetic component 69' and the at least one anti-shake magnet 661', so that at least three balls 681' are clamped between the movable carrier 67' and the frame 64', so that the movable carrier 67' and the frame 64' clamp at least three balls 681' in the height direction. Referring to Figures 18A, 18B, and 19A, there are two anti-shake magnetic elements 69', which are indirectly fixed to the movable carrier 67' by being fixed to the circuit board. Specifically, the two anti-shake magnetic elements 69' are respectively positioned between the first anti-shake coil 6621' and the second anti-shake coil 6622', so that the two anti-shake magnetic elements 69' correspond in height to the first anti-shake magnet 6611' and the second anti-shake magnet 6612', respectively. In other words, the two anti-shake magnetic elements 69' overlap in height with the first anti-shake magnet 6611' and the second anti-shake magnet 6612', respectively. It should be understood that the anti-shake magnetic elements 69' can also be directly fixed to the movable carrier 67' by insert molding or bonding, so that the magnetic attraction between at least one anti-shake magnet 661' and the anti-shake magnetic element 69' can attract the movable carrier 67' to the frame 64'. In other words, the two anti-shake magnetic elements 69 ′ are fixed to the movable carrier 67 ′ and magnetically attract the first anti-shake magnet 6611 ′ and the second anti-shake magnet 6612 ′ respectively, so that the movable carrier 67 ′ is attracted to the frame 64 ′ and clamps the anti-shake support portion 68 ′.

[0423] Further, continuing to refer to Figures 23A and 23B, in order to limit the range of movement of the ball 681', the frame 64' also includes at least three first ball grooves 647' formed on the top surface of the frame 64', and the movable carrier 67' also includes at least three second ball grooves 674' formed on the bottom surface of the movable carrier 67', wherein the top surface of the frame 64' refers to its side facing the movable carrier 67', and the bottom surface of the movable carrier 67' refers to its side facing the frame 64', and the positions of the at least three first ball grooves 647' and the at least three second ball grooves 674' correspond to each other. In one example, the anti-shake support portion 68' includes four balls 681'. Four first ball grooves 647' are formed at the four corners of the top surface of the frame 64'. Four second ball grooves 674' corresponding to the four first ball grooves 647' are formed at the four corners of the bottom surface of the movable carrier 67'. The anti-shake magnetic attraction member 69' fixed to the movable carrier 67' is magnetically attracted to at least one anti-shake magnet 661', so that the four balls 681' are respectively clamped between the four corners of the frame 64' and the four corners of the movable carrier 67'. Specifically, two first ball grooves 647' are formed on the top surface of the first frame portion 643', and another two first ball grooves 647' are formed on the top surface of the second frame portion 644'. Two second ball grooves 674' are formed on the bottom surface of the first carrier portion 671', and another two second ball grooves 674' are formed on the bottom surface of the second carrier portion 672'.

[0424] It is worth mentioning that the driving device 60' further includes a frame cover 640' fixed to the frame 64'. The frame cover 640' is disposed above the frame 64' in the height direction so that the movable carrier 67' is confined within the accommodating cavity formed by the frame cover 640' and the frame 64'. It should be understood that during a fall, the magnetic attraction between the anti-shake magnetic element 69' and the anti-shake magnet 661' makes it difficult to maintain the positional relationship between the movable carrier 67' and the frame 64'. A significant displacement of the movable carrier 67' relative to the frame 64' may cause the ball 681' to disengage from between the first ball groove 647' and the second ball groove 674'. Therefore, in the present application, a frame cover 640' is further provided to limit the height travel of the movable carrier 67', thereby preventing the ball 681' from falling off.

[0425] Furthermore, the driving device 60' can also realize the chip focusing function. Specifically, as shown in Figures 19A, 19B and 22, the driving device 60' also includes a fixed base 61' and a focusing driving unit 62'. The focusing driving unit 62' connects the fixed base 61' and the frame 64' to drive the frame 64' to move in the height direction relative to the fixed base 61'. Specifically, the frame 64' is movably arranged in the fixed base 61', and the focusing driving unit 62' is arranged between the fixed base 61' and the frame 64', so that the frame 64' is driven by the focusing driving unit 62' to move in the height direction relative to the fixed base 61'. As the frame 64' moves, the movable carrier 67', the anti-shake drive unit 66', the anti-shake support unit 68' and the anti-shake magnetic component 69' arranged in the frame 64' also move with the movement of the frame 64', and then the photosensitive component 40' fixed to the movable carrier 67' also moves with the movement of the frame 64', thereby realizing the chip focusing function.

[0426] It should be understood that the focus drive unit 62' being disposed between the frame 64' and the fixed base 61' not only includes the case where the focus drive unit 62' is disposed between the side of the frame 64' facing the fixed base 61' and the side of the fixed base 61' facing the frame 64', but also includes the case where the focus drive unit 62' is disposed between the outer side of the frame 64' away from the fixed base 61' and the outer side of the fixed base 61' away from the frame 64'. In other words, in the present application, at least a portion of the focus drive unit 62' being located between the frame 64' and the fixed base 61' is considered to mean that the focus drive unit 62' is disposed between the frame 64' and the fixed base 61'. In this way, the frame 64' or the fixed base 61' may be provided with a groove or through-hole to accommodate a portion of the focus drive unit 62'.

[0427] The driving device 60' also includes an upper cover 610' fixed to the fixed base 61'. The upper cover 610' and the fixed base 61' form a accommodating chamber to accommodate the focus driving unit 62', the frame 64', the frame cover 640', the anti-shake driving unit 66' and the movable carrier 67'. The upper cover 610' has a lens opening 6101', so that the optical lens 10' can extend from the driving device 60' through the lens opening 6101'. There is an air gap between the frame 64' and the fixed base 61' so that the focus driving unit 62' can drive the frame 64' to move in the height direction relative to the fixed base 61', thereby realizing the chip focusing function. It should be understood that in the present application, the portion of the air gap formed between the frame 64' and the fixed base 61' in the height direction is suitable for being adjusted in the realization of the chip focusing function.

[0428] Referring to Figure 22, the fixed base 61' includes a base body 611' and four base sidewalls 612' extending upward from four sides of the base body 611'. The upper cover 610' is mounted on the outer sides of the four base sidewalls 612'. Among them, one of the four base sidewalls 612' that is parallel to the length direction of the driving device 60' (i.e., the length direction of the light deflection element 30') serves as a focus fixing portion 613' for setting the focus driving portion 62'. In other words, the fixed base 61' includes a base body 611' and a focus fixing portion 613' extending upward from one side of the base body 611'. The focus fixing portion 613' is fixed to one side of the base body 611'. Specifically, the focus fixing portion 613' is fixed to the long side of the base body 611' and is parallel to the length direction of the driving device 60'. It should be understood that the focus fixing portion 613 ′ can be fixed to the base body 611 ′ by bonding or integrally forming.

[0429] It is worth mentioning that, as shown in Figures 17 to 19A, the driving device 60' may further include a supporting portion 37', wherein the supporting portion 37' has a supporting cavity for mounting the light deflecting element 30'. In other words, the light deflecting element 30' is mounted on the supporting portion 37', and the shape of the supporting cavity of the supporting portion 37' is adapted to the shape of the light deflecting element 30'. That is, in one embodiment of the present application, the light deflecting element 30' is fixed by being mounted on the supporting portion 37'. For example, when the light deflecting element 30' is implemented as a trapezoidal prism, the supporting cavity of the supporting portion 37' has a size that gradually decreases from top to bottom. In a specific example of the present application, the bearing portion 37' is fixed to the middle of the fixed base 61' by bonding. Specifically, the base body 611' has an opening arranged toward the light deflection element 30', and the bearing portion 37' is arranged in the opening of the fixed base 61' and fixed to the opening of the fixed base 61'; in another specific example of the present application, the bearing portion 37' can also be integrally formed in the middle of the fixed base 61', for example, the bearing portion 37' and the fixed base 61' are directly integrally formed by injection molding.

[0430] Continuing with reference to Figures 19A, 19B and 22, the focus drive unit 62' is arranged between the frame 64' and the focus fixing part 613' of the fixed base 61', and the focus drive unit 62' includes a pair of focus magnets 621' and a pair of focus coils 622'. The focus magnet 621' is fixed to one of the frame 64' and the focus fixing part 613', and the focus coil 622' is fixed to the other of the frame 64' and the focus fixing part 613'. The focus magnet 621' and the focus coil 622' are arranged relative to each other, so that the frame 64' can be driven to move in the height direction relative to the fixed base 61' by the magnetic force between the focus magnet 621' and the focus coil 622' to realize the chip focusing function.

[0431] In a specific example, the focusing magnet 621' is fixed to the side of the frame 64', the focusing coil 622' is fixed to the focus fixing portion 613' of the fixed base 61', and the focusing coil 622' is arranged opposite to the focusing magnet 621'. In other words, the focusing coil 622' and the focusing magnet 621' are arranged horizontally between the frame 64' and the focus fixing portion 613' of the fixed base 61', and the focus drive unit 62' includes the focusing coil 622' and the focusing magnet 621' arranged opposite to each other in the horizontal direction, and the horizontal direction refers to the direction perpendicular to the optical axis of the optical lens 10'. In this way, a larger driving force in the height direction can be provided with a smaller lateral dimension (dimensions in the length and width directions).

[0432] It should be understood that during chip focusing, the focus coil 622', fixed to the focus fixing portion 613', drives the focus magnet 621' to move in the height direction relative to the focus coil 622'. Consequently, the frame 64', fixed to the focus magnet 621', moves in the height direction in tandem with the movement of the focus magnet 621'. In other words, in this example, during chip focusing, the focus magnet 621' acts as a mover, and the focus coil 622' acts as a stator.

[0433] Furthermore, the focus drive unit 62' also includes a focus circuit board 623', and the focus coil 622' is fixed and electrically connected to the focus circuit board 623'. The focus circuit board 623' is fixed to the focus fixing unit 613', so that the focus coil 622' is indirectly fixed to the focus fixing unit 613' through the focus circuit board 623'. In a specific example, the focus circuit board 623' is attached to the outer side surface of the focus fixing unit 613', and a through hole is provided on the focus fixing unit 613' to expose the focus coil 622' and to face the focus magnet 621'. The through hole on the focus fixing unit 613' accommodates the focus coil 622', so that the lateral size of the drive device 60' can be reduced. It should be understood that the outer side surface of the focus fixing unit 613' refers to the side of the focus fixing unit 613' away from the frame 64'. It is worth mentioning that the focusing circuit board 623' is further electrically connected to the chip circuit board 42'. The focusing circuit board 623' can be a flexible circuit board or a hard-soft combination board. In this way, the focusing circuit board 623' can be arranged in the driving device 60' in a bent state so that the focusing circuit board 623' can be extended to a position that is convenient for electrical connection with the chip circuit board 42'.

[0434] Accordingly, the focusing magnet 621' is installed on the outer side surface of the frame 64' so that a smaller distance can be maintained between the focusing magnet 621' and the focusing coil 622', thereby enhancing the magnetic force between the focusing magnet 621' and the focusing coil 622'. Specifically, the focusing magnet 621' is installed on the outer side surface of the second frame portion 644', and the outer side surface of the second frame portion 644' has a groove to accommodate the focusing magnet 621'. In this way, the size of the driving device 60' and the camera module 1' can be reduced. It should be understood that the outer side surface of the frame 64' refers to the side of the frame 64' facing the fixed base 61' or the upper cover 610', and the outer side surface of the second frame portion 644' refers to the side of the second frame portion 644' facing the focus fixing portion 613'.

[0435] It is worth mentioning that in the present application, as shown in FIG19A , since the focusing magnet 621' is arranged on the side of the focusing fixing portion 613' of the fixed base 61', the bottom surface of the focusing magnet 621' can be lower than the top surface of the light turning element 30'. In other words, the focusing magnet 621' extends downward, so that the relative area between the focusing magnet 621' and the focusing coil 622' can be increased, thereby enhancing the driving force of the focus driving portion 62'. Furthermore, in the present application, the focusing magnet 621', the first anti-shake magnet 6611' and the second anti-shake magnet 6612' are all arranged on the circumferential side of the light turning element 30', so that the height dimensions of the driving device 60' and the camera module 1' can be designed to be smaller.

[0436] It is worth mentioning that in the present application, the first frame portion 643' and the frame connecting portion 645' are used to mount the first anti-shake magnet 6611' and the second anti-shake magnet 6612', respectively, and the second frame portion 644' is used to mount the focus magnet 621'. The frame 64' includes an anti-shake frame 642' and a focus frame 641'. The first frame portion 643' and the frame connecting portion 645' form an "L"-shaped anti-shake frame 642', and the second frame portion 644' forms the focus frame 641'. The anti-shake frame 642' and the focus frame 641' are connected by an integral molding method. Furthermore, as shown in Figure 23A, the focus magnet 621' is fixed to the outer side surface of the frame 64', and at least one anti-shake magnet 661' (the first anti-shake magnet 6611' and the second anti-shake magnet 6612') is fixed to the top surface of the frame 64'. In other words, the first anti-shake magnet 6611', the second anti-shake magnet 6612' and the focusing magnet 621' are respectively arranged on three sides of the light deflection element 30', wherein the first anti-shake magnet 6611' and the focusing magnet 621' are relatively arranged on the two long sides of the light deflection element 30'. It should be understood that the light deflection element 30' is in the shape of a long strip, and when viewed from the direction of light incident on the optical lens 10', it has two opposite long sides and two opposite short sides.

[0437] It should be understood that in the present application, the first anti-shake coil 6621' and the second anti-shake coil 6622' are arranged above the first anti-shake magnet 6611' and the second anti-shake magnet 6612', and the focus coil 622' is located on the outside of the focus magnet 621'. In this way, the first anti-shake coil 6621' and the second anti-shake coil 6622' can be directly electrically connected to the chip circuit board 42' of the photosensitive component 40' upward, while the focus coil 622' is electrically connected to the photosensitive component 40' from the outside. The magnet-coil setting method of the present application optimizes the electrical connection setting method of the camera module 1' and makes the electrical connection setting method simpler.

[0438] In the present application, the driving device 60' also includes a pair of focusing guides 65' and a pair of focusing magnetic parts 63'. The focusing guide 65' is arranged between the frame 64' and the fixed base 61' to maintain an air gap between the frame 64' and the fixed base 61', thereby reducing the resistance encountered by the frame 64' when moving relative to the fixed base 61'. In a specific example, the focusing guide 65' can be implemented as a guide rod 651', and the focusing guide 65' includes two guide rods 651'. Specifically, the two guide rods 651' are vertically arranged between the second frame portion 644' of the frame 64' and the focus fixing portion 613' of the fixed base 61', so that the frame 64' and the fixed base 61' maintain a fixed gap in the horizontal direction. Furthermore, in this embodiment, two guide rods 651 ′ are respectively provided on both sides of the focus driving portion 62 ′, and the two guide rods 651 ′ have the same size to prevent the frame 64 ′ and the focus fixing portion 613 ′ from tilting.

[0439] The focusing magnetic member 63' is fixed to the focusing fixing portion 613' of the fixed base 61' by being attached to the back of the focusing circuit board 623', that is, in the width direction, the focusing magnet 621', the focusing coil 622', the focusing circuit board 623' and the focusing magnetic member 63' are arranged in sequence. Among them, the side of the focusing circuit board 623' on which the focusing coil 622' is arranged is the front side of the focusing circuit board 623', and the other opposite side is the back side of the focusing circuit board 623'. The focusing magnetic member 63' is made of a material suitable for being attracted by a magnet, and it is magnetically attracted to the focusing magnet 621' so that the frame 64' is adsorbed toward the focusing fixing portion 613' of the fixed base 61' in the width direction. The frame 64' and the focusing fixing portion 613' of the fixed base 61' clamp two guide rods 651' in the width direction. The focusing magnetic member 63' can be made of an iron-containing material.

[0440] In other words, the focus guide portion 65' is arranged between the second frame portion 644' of the frame 64' and the focus fixing portion 613' of the fixed base 61', the focus magnetic component 63' is fixed to the focus fixing portion 613', and the focus magnetic component 63' and the focus magnet 621' are magnetically attracted to each other so that the focus guide portion 65' is clamped between the second frame portion 644' of the frame 64' and the focus fixing portion 613' of the fixed base 61'.

[0441] In a specific example, two first guide rails 6131' extending in the height direction are formed on the inner side surface of the focus fixing portion 613' opposite the frame 64', and two second guide rails 646' extending in the height direction are formed on the outer side surface of the frame 64' opposite the focus fixing portion 613' (i.e., the outer side surface of the second frame portion 644'). The two first guide rails 6131' and the two second guide rails 646' are respectively provided. Two guide rods 651' are respectively provided between the two first guide rails 6131' and the two second guide rails 646', and are clamped between the frame 64' and the focus fixing portion 613' due to the magnetic attraction between the focus magnetic member 63' and the focus magnet 621'.

[0442] It is worth mentioning that in one example of the present application, the two guide rods 651' may not be fixed, and they are only clamped by the frame 64' and the focus fixing part 613'; in another example of the present application, the positions of the two guide rods 651' may also be fixed, for example, they can be fixed to the fixed base 61' by fixing the bottom end of the guide rod 651' to the fixed base 61' and / or fixing the top end of the guide rod 651' to the upper cover 610', or, the two guide rods 651' are only restricted between the upper cover 610' and the fixed base 61' by the snap fit between the upper cover 610' and the fixed base 61', or, the two guide rods 651' can be fixed to the frame 64' or the focus fixing part 613'.

[0443] It is worth noting that in the above embodiment, since the light deflection element 30' disposed between the optical lens 10' and the photosensitive assembly 40' is relatively long, in order to reduce the overall size of the camera module 1', the frame 64' has an opening toward the light deflection element 30', thereby forming a "Π" shape around the light deflection element 30'. Consequently, the frame 64' can only be provided with the first anti-shake magnet 6611', the second anti-shake magnet 6612', and the focus magnet 621' on three sides. The first anti-shake magnet 6611' and the second anti-shake magnet 6612' need to be disposed perpendicularly to each other to achieve translation in two perpendicular directions. Therefore, one of the first anti-shake magnet 6611' and the second anti-shake magnet 6612' needs to be disposed on a short side of the drive device 60', while the other of the first anti-shake magnet 6611' and the second anti-shake magnet 6612' and the focus magnet 621' are disposed on two opposing long sides of the drive device 60'.

[0444] Specifically, the first anti-shake magnet 6611' is mounted on the top surface of the first frame portion 643' located on the long side of the driving device 60', the second anti-shake magnet 6612' is mounted on the top surface of the frame connection portion 645' located on the short side of the driving device 60', and the focusing magnet 621' is mounted on the outer side of the second frame portion 644' located on the long side of the driving device 60'. The focusing magnet 621', the first anti-shake magnet 6611', and the second anti-shake magnet 6612' are flat rectangular parallelepipeds, with the largest side of the focusing magnet 621' being perpendicular to the largest side of the first anti-shake magnet 6611', and the largest side of the focusing magnet 621' being perpendicular to the largest side of the second anti-shake magnet 6612'. Correspondingly, the plane where the focusing coil 622' is located is perpendicular to the plane where the first anti-shake coil 6621' is located and the plane where the second anti-shake coil 6622' is located, respectively. The plane where the focusing coil 622' (or the first anti-shake coil 6621', the second anti-shake coil 6622') is located refers to the plane where its largest area is located.

[0445] Furthermore, in one example, the magnetic pole direction of the first anti-shake magnet 6611' is perpendicular to the magnetic pole direction of the second anti-shake magnet 6612', and the magnetic pole direction of the focus magnet 621' is perpendicular to the plane containing the magnetic pole directions of the first anti-shake magnet 6611' and the magnetic pole directions of the second anti-shake magnet 6612'. In this way, the driving direction of the focus drive unit 62' is perpendicular to the driving direction of the anti-shake drive unit 66'. In this application, the magnetic pole direction of the magnet refers to the direction in which the S pole of the magnet points to the N pole. Accordingly, the focus coil 622', the first anti-shake coil 6621', and the second anti-shake coil 6622' are all runway-type coils, wherein the winding plane of the focus coil 622' and the winding plane of the first anti-shake coil 6621' are perpendicular to each other, and the winding plane of the focus coil 622' and the winding plane of the second anti-shake coil 6622' are perpendicular to each other.

[0446] It should be understood that in the present application, since the focusing magnet 621' and the first anti-shake magnet 6611' are respectively disposed on the side and top surfaces of the frame 64', and the focusing magnet 621' and the first anti-shake magnet 6611' have different dimensions, in one example, the optical lens 10', the light deflection element 30', and the photosensitive component 40' are eccentrically disposed in the drive device 60' in the width direction.

[0447] Furthermore, the photosensitive component 40' also includes a connecting circuit board 44', which is fixed and electrically connected to the chip circuit board 42' to provide electrical conduction between the chip circuit board 42' and external electronic devices. The applicant has discovered that when the photosensitive component 40' is driven by the driving device 60' to achieve movement, the connecting circuit board 44' becomes one of the sources of resistance to the movement of the photosensitive component 40'. Therefore, in this application, the applicant further improves the connecting circuit board 44' of the photosensitive component 40' to reduce the resistance encountered by the photosensitive component 40' when being driven to achieve chip anti-shake or chip focus.

[0448] As shown in Figures 19A, 19B, and 23A, connection circuit board 44' includes an inner circuit board 441', an outer circuit board 443', and a flexible conductive mechanism 442' connecting inner circuit board 441' and outer circuit board 443'. Inner circuit board 441' is secured to and electrically connected to chip circuit board 42'. Inner circuit board 441' is positioned inside outer circuit board 443', which is secured to drive device 60'. Flexible conductive mechanism 442' electrically connects inner circuit board 441' and outer circuit board 443', enabling electrical communication between chip circuit board 42' and external electronic devices via outer circuit board 443'. It should be understood that electrical communication between chip circuit board 42' and inner circuit board 441' can be achieved by providing an electrical connection medium, such as solder paste, between chip circuit board 42' and inner circuit board 441'.

[0449] In one example of the present application, the inner circuit board 441' is disposed on the back side of the chip circuit board 42', with the side of the chip circuit board 42' facing the light deflection element 30' being the front side, and the side of the chip circuit board 42' away from the light deflection element 30' being the back side. The photosensitive chip 41' is mounted on the front side of the chip circuit board 42'. In other words, the inner circuit board 441' is disposed above the chip circuit board 42' and between the chip circuit board 42' and the frame cover 640'. Furthermore, the outer circuit board 443' and the flexible conductive mechanism 442' are also disposed above the chip circuit board 42' and between the chip circuit board 42' and the frame cover 640'.

[0450] Furthermore, to reduce the lateral dimensions of drive device 60', in a specific example of the present application, on at least one side of chip circuit board 42', the dimensions of inner circuit board 441' are smaller than those of chip circuit board 42'. That is, the length of inner circuit board 441' is smaller than the length of chip circuit board 42' and / or the width of inner circuit board 441' is smaller than the width of chip circuit board 42'. In other words, the area of ​​inner circuit board 441' can be smaller than the area of ​​chip circuit board 42'. In this way, connecting circuit board 44' can be made as small as possible in the horizontal direction, thereby minimizing the increase in the horizontal dimensions of drive device 60'.

[0451] Furthermore, in the present application, the connecting circuit board 44' extends laterally above the light deflection element 30' and above the anti-shake drive unit 66'. This utilizes the structure where the anti-shake drive unit 66' is positioned around the light deflection element 30', allowing for a larger connecting circuit area, thereby achieving a better drag reduction effect. It should be understood that at least a portion of the connecting circuit board 44' overlaps the light deflection element 30' in the height direction.

[0452] Specifically, as shown in conjunction with Figures 19A and 23A , the lateral extension direction of the connecting circuit board 44' is perpendicular to the longitudinal direction of the light deflecting element 30'. In other words, the longest side of the connecting circuit board 44' is perpendicular to the longitudinal direction of the light deflecting element 30'. Because the optical lens 10' and the photosensitive component 40' are disposed together along the longitudinal direction on the same side of the light deflecting element 30', the space for arranging the connecting circuit board 44' along the longitudinal direction of the light deflecting element 30' is relatively small. To maximize the internal space of the camera module 1' and reduce the size of the camera module 1', the connecting circuit board 44' is larger in the longitudinal direction perpendicular to the light deflecting element 30'.

[0453] Continuing with Figures 19A, 19B, and 23A, flexible conductive mechanism 442' electrically connects inner circuit board 441' and outer circuit board 443'. Flexible conductive mechanism 442' is easily deformable. When driving device 60' drives chip circuit board 42', to which photosensitive chip 41' is affixed, to move, inner circuit board 441', which is affixed to chip circuit board 42', experiences less resistance from flexible conductive mechanism 442'. In other words, because flexible conductive mechanism 442' is easily deformable, chip circuit board 42' and inner circuit board 441' easily move relative to outer circuit board 443'. Consequently, the driving force of driving device 60' can be designed to be relatively small, thereby reducing the size of driving device 60'. It is worth noting that flexible conductive mechanism 442' is more easily deformable than either outer circuit board 443' or inner circuit board 441'.

[0454] The flexible conductive mechanism 442' includes at least two flexible conductive arms 4421'. The at least two flexible conductive arms 4421' extend between and connect the inner circuit board 441' and the outer circuit board 443'. The flexible conductive arms 4421' can electrically connect the inner circuit board 441' and the outer circuit board 443'. In one example of the present application, the flexible conductive mechanism 442' may include two flexible conductive arms 4421' disposed on opposite sides of the inner circuit board 441' along the width direction. In another example of the present application, as shown in FIG. 23A , the flexible conductive mechanism 442' may include four flexible conductive arms 4421', two of which are disposed on one side of the inner circuit board 441' along the width direction, and the other two flexible conductive arms 4421' are disposed on the other side of the inner circuit board 441' along the width direction. In other words, the extension direction of the flexible conductive mechanism 442' is perpendicular to the length direction of the light deflection element 30'.

[0455] Furthermore, the flexible conductive arm 4421' may include one or more flexible electrical connectors. When the number of flexible electrical connectors is designed to be large, more conductive circuits can be provided between the inner circuit board 441' and the outer circuit board 443'. Specifically, the number of flexible electrical connectors in the flexible conductive arm 4421' is determined according to the circuit requirements of the photosensitive chip 41'.

[0456] 19A and 19B , in one example of the present application, the external circuit board 443' is directly or indirectly fixed to the frame 64'. For example, the external circuit board 443' may be directly fixed to the top surface of the frame 64', or the external circuit board 443' is fixed to the bottom surface of the frame cover 640' and thus indirectly fixed to the frame 64', or the external circuit board 443' is clamped by the frame cover 640' and the frame 64' and fixed between the frame cover 640' and the frame 64'. The outer circuit board 443' is higher than the inner circuit board 441', that is, the top surface of the outer circuit board 443' is higher than the top surface of the inner circuit board 441'. Furthermore, the bottom surface of the outer circuit board 443' may also be higher than the bottom surface of the inner circuit board 441'. In this way, there is an air gap between the inner circuit board 441' and the frame cover 640', and there is an air gap between the outer circuit board 443' and the chip circuit board 42', so that the inner circuit board 441' and the chip circuit board 42' will not rub against the frame cover 640' or the outer circuit board 443' during movement, thereby reducing the resistance to movement. In this example, the flexible conducting arm 4421' is inclined to connect the inner circuit board 441' and the outer circuit board 443', wherein the end of the flexible conducting arm 4421' connected to the outer circuit board 443' is higher than the end connected to the inner circuit board 441'. During the horizontal movement of the chip circuit board 42', the possibility of friction between the flexible conducting arm 4421' and the chip circuit board 42' is...
