Description

Technical Field

[0001] This disclosure relates to the field of camera structure technology, and in particular to a camera module and electronic device. Background Technology

[0002] With the continuous development of electronic devices, the functions of camera modules on electronic devices have become increasingly rich. Some camera modules adopt the periscope principle, using an optical path commutator to bend the originally straight optical path into a 90-degree angle, thereby converting the thickness of the lens into length and achieving a longer focal length. This allows mobile phones to have stronger optical zoom capabilities without increasing the thickness of the electronic device.

[0003] However, the excessive length of this type of camera module significantly occupies the motherboard area of ​​electronic devices, causing sacrifices in other aspects such as heat dissipation and battery capacity, thus reducing the user experience. Summary of the Invention

[0014] Furthermore, the protrusion is provided with an abutment surface that connects to the lens; the abutment surface is arc-shaped, and the plurality of protrusions form a circular limiting space.

[0015] Furthermore, in the second direction, the projection of the second segment covers the optical path commutator.

[0016] Furthermore, the first segment is circular, and the second segment is rectangular; in the second direction, the four corners of the projection of the second segment are located outside the projection of the first segment.

[0017] Furthermore, the mounting base has a light-shielding wall on the side facing the optical path commutator; in the second direction, the light-shielding wall extends beyond the light-incident side of the optical path commutator.

[0018] Furthermore, the light-shielding wall is arranged around the light-transmitting hole and has a notch on the side facing the photosensitive sensor.

[0019] Furthermore, the optical path commutator includes a prism, which has an incident surface perpendicular to the second direction and an exit surface perpendicular to the first direction.

[0020] Furthermore, the optical path commutator also includes a housing, and the prism is fixed inside the housing; the housing is provided with a first opening opposite to the incident surface and a second opening opposite to the exit surface; the photosensor is assembled at the second opening.

[0042] The embodiments described in this specification will now be described in detail.

[0043] Some camera modules operate on the periscope principle, using an optical path commutator to bend the originally straight optical path by 90 degrees, thereby converting the lens thickness into length and achieving a longer focal length. Currently, such camera modules are excessively long, occupying a significant amount of space within electronic devices. This disclosure provides a camera module and electronic device to solve these related technical problems.

[0044] like Figure 1 and Figure 2 As shown, this disclosure provides a camera module 2, applied to an electronic device 1. The camera module 2 includes a lens 10, an optical path commutator 20, and a photosensitive sensor 30. The photosensitive sensor 30 is located on one side of the optical path commutator 20 in a first direction and is aligned with the optical path commutator 20 in the first direction. The lens 10 is located on one side of the optical path commutator 20 in a second direction different from the first direction. The lens 10 is aligned with the optical path commutator 20 in the second direction so that light passes through the lens 10 and the optical path commutator 20 to the photosensitive sensor 30.

[0045] Since the lens 10 is positioned on one side of the optical path commutator 20 in the first direction and the photosensitive sensor 30 is positioned on one side of the optical path commutator 20 in the second direction, the optical path commutator 20 is located between the lens 10 and the photosensitive sensor 30 in the direction of light propagation. Because the first direction and the second direction are different, the volume occupied by the camera module 2 in a single direction can be reduced, thereby making the camera module 2 more compact.

[0046] During shooting, light is focused by lens 10, reflected by optical transducer 20, and then directed to photosensitive sensor 30 to generate image information. Because the area of ​​light received by optical transducer 20 after being focused by lens 10 is relatively small, the overall size of optical transducer 20 can be reduced, further improving the compactness of camera module 2.

[0047] The first direction can be the direction of the central axis of the lens 10, and the second direction can be the direction perpendicular to the light-receiving surface of the photosensitive sensor 30, which can ensure that the image information does not produce oblique distortion after reaching the photosensitive sensor 30. In other embodiments, the first and second directions can also be set at an angle, and additional lenses can be used to compensate for image distortion.

[0048] In one embodiment, such as Figure 3 and Figure 4 As shown, lens 10 may include a movable lens module 11. The movable lens module 11 may include a bracket 111, a lens assembly 112, and a drive assembly 113. The lens assembly 112 is assembled to the bracket 111. The bracket 111 may be annular, and the lens assembly 112 is mounted on the inner side of the bracket 111. The drive assembly 113 is poweredly connected to the bracket 111. The drive assembly 113 can drive the bracket 111 to move the lens assembly 112, performing functions such as focusing or image stabilization.

[0049] Taking the focusing function as an example, the drive component 113 can drive the lens group 112 to move along the second direction to adjust the focal length of the lens 10. Taking the image stabilization function as an example, the drive component 113 can drive the lens group 112 to move along a direction perpendicular to the second direction to perform image stabilization. When the camera module 2 shakes, the drive component 113 can perform shake compensation and drive the lens group 112 to move in the opposite direction relative to the shake, thereby achieving an image stabilization effect.

[0050] The lens group 112 performs a translational motion in a plane perpendicular to the second direction, which has less impact on the acquired image compared to traditional prism oscillation image stabilization. When a prism oscillates, even a small oscillation angle can cause a large positional change in the acquired image range. However, when the lens group 112 performs a tiny translational motion, the acquired image range only undergoes a tiny translational change.

[0051] In one embodiment, the drive assembly 113 may be annular, with the bracket 111 and lens group 112 mounted inside the drive assembly 113. The drive assembly 113 may be configured with a corresponding structure to generate driving force. In one embodiment, the bracket 111 is provided with a first electromagnetic induction element (not shown in the figure), and the drive assembly 113 is provided with a second electromagnetic induction element (not shown in the figure). The first electromagnetic induction element and the second electromagnetic induction element cooperate to drive the lens group 112 to move.

[0052] The driving force generated by the change of magnetic field drives the lens group 112 to move. This simple structure allows for a more compact camera module 2. In other embodiments, the lens group 112 can also be moved by installing a linear motor on the drive assembly 113 and setting gears or guide rods, achieving higher precision. The specific operating mode of the drive assembly 113 is not limited.

[0053] The drive assembly 113 can drive the lens group 112 to move only along the second direction for focusing. The drive assembly 113 can also drive the lens group 112 to move only perpendicular to the second direction for image stabilization. To address different usage scenarios, the drive assembly 113 can have only one function—focusing or image stabilization—simplifying the structure and further improving the compactness of the camera module 2. Alternatively, the drive assembly 113 can simultaneously drive the lens group 112 to move both along and perpendicular to the second direction, enhancing the functionality of the camera module 2.

[0054] In one embodiment, the lens 10 may further include a fixed lens module 12. The fixed lens module 12 is coaxially arranged with the movable lens module 11. By setting a relatively movable movable lens module 11 and a relatively stationary fixed lens module 12, the focusing range of the lens 10 can be increased by utilizing the refraction between multiple lens modules, thus improving the experience of telephoto and macro shooting. Furthermore, within the same focusing range, the focusing travel is reduced, further improving the compactness of the camera module 2.

[0055] In one embodiment, the fixed lens module 12 can be mounted to the optical path commutator 20. Since the optical path commutator 20 and the fixed lens module 12 are relatively fixed in position on the camera module 2, assembling the two together allows the fixed-position components to be clustered together, reducing installation difficulty, improving assembly efficiency, and increasing assembly yield.

[0056] In one embodiment, such as Figure 3 and Figure 5 As shown, the optical path commutator 20 can be a prism 22. The prism 22 is provided with an incident surface 201, an exit surface 202, and a reflecting surface 203. The incident surface 201 is perpendicular to the first direction, and the exit surface 202 is perpendicular to the second direction to avoid image distortion.

[0057] In one embodiment, the incident surface 201 and the exit surface 202 may be perpendicular. After the light enters the optical path commutator 20 along the second direction, it rotates 90 degrees and then travels along the first direction to the photosensitive sensor 30. The size of the camera module 2 in the first direction is further compressed, thereby further improving the compactness of the camera module 2. In other embodiments, the incident surface 201 and the exit surface 202 may be inclined towards each other, and their specific positional relationship is not limited.

[0058] In one embodiment, the reflective surface 203 may be connected to the incident surface 201 and the exit surface 202 respectively, and is inclined relative to the incident surface 201 and the reflective surface 203. The reflective surface 203 intersects the optical axis of the lens 10, so that light passes through the lens 10, the incident surface 201, the reflective surface 203 and the exit surface 202 to the photosensor 30.

[0059] The prism 22 is triangular prism in shape, with a simple structure and easy manufacturing. In other embodiments, the specific structure of the reflecting surface 203 is not limited, as long as it enables light to be reflected and directed towards the photosensitive sensor 30. For example, the reflecting surface 203 can be composed of multiple planes, achieving light reversal through multiple reflections, which can increase the distance the light travels and increase the focal length, thereby enabling the capture of images from a greater distance.

[0060] In one embodiment, the optical path converter 20 can be a reflector (not shown in the figure), through which light propagates to the photosensitive sensor 30 via the lens 10 and the reflector. By setting the reflector, the light propagates through the air, directly contacts the reflector and is reflected, avoiding light attenuation when passing through different media, ensuring the brightness of the light, and improving the imaging clarity of the camera module 2.

[0061] In one embodiment, such as Figure 5 As shown, the optical path commutator 20 may also include a housing 21. The prism 22 is fixed inside the housing 21. By installing the prism 22 inside the housing 21 and fixing it relatively, the magnets and coils used to control the movement of the prism 22 are eliminated, thereby reducing the space occupied by the camera module 2 and reducing the area occupied by the camera module 2 on the motherboard of the electronic device 1.

[0062] The housing 21 may include a mounting plate 211, a pair of side plates 212, and a protruding plate 213. The mounting plate 211, side plates 212, and protruding plate 213 together form a receiving space 210, within which the prism 22 is fixed. The receiving space 210, formed by the enclosure of the plates, further saves space and reduces the volume occupied by the camera module 2. The specific structure of the housing 21 is not limited, as long as there is space inside for mounting the prism 22.

[0063] In an embodiment where the driving component 113 can drive the lens group 112 to move perpendicular to the second direction, the prism 22 is installed inside the housing 21 and the driving component 113 drives the lens group 112 to translate and stabilize the image. This allows the camera module 2 to eliminate the need for components such as magnets and coils, reduce space occupation, and still have the function of image stabilization, thus comprehensively improving the user experience of the camera module 2.

[0064] The housing 21 is provided with a first opening 214 and a second opening 215. The first opening 214 is disposed opposite to the incident surface 201, and the second opening 215 is disposed opposite to the exit surface 202, for passing light so that images can be captured normally. In an embodiment where the housing 21 includes a mounting plate 211, a side plate 212, and a protruding plate 213, the first opening 214 can be formed by the sides of the mounting plate 211, the side plate 212, and the protruding plate 213, and the second opening 215 can be formed by the sides of the side plate 212 and the protruding plate 213, so as to further improve the compactness of the camera module 2.

[0065] In one embodiment, the photosensor 30 can be assembled at the second opening 215. The prism 22 and the photosensor 30 are assembled on the same component, improving the assembly efficiency of the camera module 2. At the same time, reducing the distance between the prism 22 and the photosensor 30 makes the camera module 2 more compact.

[0066] The specific assembly method of the photosensor 30 is not limited. In one embodiment, such as... Figure 3 As shown, the photosensor 30 includes a mounting base 31, a photosensing module 32, and a circuit board 33. The photosensing module 32 is fixed to and electrically connected to the circuit board 33. A groove 311 may be provided on the mounting base 31, and the photosensing module 32 and the circuit board 33 are snapped into the groove 311, resulting in a simple structure and improved installation efficiency. In embodiments where the housing 21 includes a protruding plate 213, as... Figure 3 and Figure 5 As shown, the assembly formed by the mounting base 31, the photosensitive module 32 and the circuit board 33 can be snapped onto the protruding plate 213, further shortening the assembly time.

[0067] In one embodiment, such as Figure 3 and Figure 5 As shown, the camera module 2 may also include a mounting base 40. The mounting base 40 has a light-transmitting hole 41, and the lens 10 and the optical path commutator 20 are respectively assembled to both ends of the light-transmitting hole 41. Mounting the lens 10 and the optical path commutator 20 onto the same component improves assembly yield. Specifically, the fixed lens module 12 and the prism 22 can be respectively snapped onto both sides of the mounting base 40. The light-emitting end of the fixed lens module 12 faces the light-transmitting hole 41, and the incident surface 201 of the prism 22 faces the other end of the light-transmitting hole 41.

[0068] In one embodiment, such as Figure 6 As shown, the light-transmitting aperture 41 may include a first section 411 and a second section 412 coaxially arranged. The first section 411 faces the lens 10, and the second section 412 faces the optical path commutator 20. The inner diameter of the first section 411 is larger than that of the second section 412. The fixed lens module 12 can be snapped onto the first section 411, and the prism 22 can be snapped onto the second section 412. In an embodiment where the optical path commutator 20 includes a housing 21, the prism 22 is installed inside the housing 21, and the housing 21 can be snapped and fixed to the mounting base 40.

[0069] By configuring the light-transmitting aperture 41 into two sections with different inner diameters, the imaging clarity of the camera module 2 can be improved. On one hand, the first section 411, with a larger inner diameter, can increase the amount of light entering the camera. On the other hand, since light is focused after passing through the lens 10, the second section 412, with a smaller inner diameter, matches the size of the image after focusing by the lens 10, and can block areas outside the image receiving area, preventing excess light from interfering with the image. In other embodiments, the light-transmitting aperture 41 can be a through hole with the same inner diameter, which facilitates processing and improves production efficiency.

[0070] In one embodiment, such as Figure 6 As shown, the inner wall of the first section 411 may be provided with multiple protrusions 413. The lens 10 extends into the first section 411 and abuts against the protrusions 413 radially. The lens 10 extending into the first section 411 reduces the installation space required for the camera module 2, further improving its compactness. The specific fixing method of the lens 10 is not limited; it can also be fixed by screws or other methods, facilitating disassembly and maintenance.

[0071] In one embodiment, such as Figure 6 and Figure 8 As shown, the protrusion 413 is provided with an abutment surface 4131 for connecting the lens 10. The abutment surface 4131 is arc-shaped, and multiple protrusions 413 form a circular limiting space 4130. Since the lens 10 is cylindrical in shape, the arc-shaped abutment surface 4131 can improve the fit between the lens 10 and the protrusion 413, thereby increasing the fixing strength. In other embodiments, the abutment surface 4131 may be serrated, which increases the fixing strength of the lens 10 by increasing friction.

[0072] In one embodiment, in the second direction, the projection of the second segment 412 covers the optical path commutator 20. Light can be completely transmitted to the optical path commutator 20 via the second segment 412, ensuring the integrity of the transmitted image. In other embodiments, the projection range of the second segment 412 may be smaller than the projection range of the optical path commutator 20. In this embodiment, the image range that can be clearly projected onto the optical path commutator 20 can be calculated based on the optical focusing range of the lens 10, and the size of the second segment 412 can be set according to this image range, so that the projection of the second segment 412 can exceed the image range. This setting can further prevent light outside the image range from affecting the imaging, improving the imaging clarity of the camera module 2.

[0073] In one embodiment, such as Figure 8 As shown, the first segment 411 can be circular, and the second segment 412 can be rectangular. In the second direction, the four corners of the projection of the second segment 412 are located outside the projection of the first segment 411. This arrangement can increase the area of ​​the second segment 412, further increasing the amount of light reaching the optical path commutator 20 through the second segment 412, improving the brightness of the image and ensuring the integrity of the image.

[0074] In one embodiment, such as Figure 7 As shown, the mounting base 40 may have a light-shielding wall 42 on the side facing the optical path commutator 20. In a second direction, the light-shielding wall 42 extends beyond the light-incident side of the optical path commutator 20. In an embodiment where the optical path commutator 20 is a prism 22, the light-shielding wall 42 extends beyond the incident surface 201 of the prism 22. In an embodiment where the optical path commutator 20 is a reflector, the light-shielding wall 42 extends beyond the side of the reflector located on the incident light side. By providing the light-shielding wall 42, lateral light can be prevented from passing through the mounting gap between the optical path commutator 20 and the mounting base 40, thus avoiding interference with imaging and improving the clarity of the image.

[0075] In one embodiment, such as Figure 7 As shown, the light-shielding wall 42 is arranged around the light-transmitting hole 41 and has a notch 43 on the side facing the photosensitive sensor 30. By providing the notch 43, it is possible to ensure that there is no obstruction on the side facing the photosensitive sensor 30, thereby further improving the clarity of the image.

[0076] The specific structural form of the light-shielding wall 42 and the notch 43 is not limited. In one embodiment, the light-shielding wall 42 can be strip-shaped, which is simple in structure and easy to manufacture. In an embodiment where the second section 412 is rectangular, the strip-shaped light-shielding wall 42 can be arranged around three sides of the rectangle. The light-shielding wall 42 forms a notch 43 at the fourth side, which further simplifies the structure and improves manufacturing efficiency.

[0077] like Figure 1As shown, this disclosure also provides an electronic device 1, including a device body 50, a housing 60, and the aforementioned camera module 2. The housing 60 has a camera hole 61, and the camera module 2 is aligned with the camera hole 61 in a second direction. The device body 50 includes a motherboard 51, and the camera module 2 is assembled onto the motherboard 51 along the second direction. In the second direction, the area occupied by the projection of the camera module 2 on the motherboard 51 is relatively small, allowing more components to be installed within the electronic device 1, enriching its functionality, and improving space utilization. The electronic device 1 of this disclosure can be a mobile phone, a tablet computer, etc., and the specific type is not limited.

[0078] The second direction can be the thickness direction of electronic device 1. The first direction can be the length or width direction of electronic device 1. The camera module 2 rotates the image by 90°, which reduces the volume occupied by the camera module 2 in the thickness direction and the length or width direction of electronic device 1, further improving the compactness of the camera module 2 and improving the space utilization inside electronic device 1.

[0079] like Figure 1 and Figure 5 As shown, in the embodiment where the optical path commutator 20 includes a mounting plate 211, the mounting plate 211 is located on the side of the optical path commutator 20 facing the motherboard 51. The mounting plate 211 is inclined relative to the motherboard 51 and forms a mounting space 200 with the motherboard 51. The camera module 2 is partially suspended relative to the motherboard 51, further reducing the area occupied by the motherboard 51. At the same time, the mounting space 200 formed by the suspended position can accommodate other components within the electronic device 1.
