Description

Technical Field

[0001] The present application relates to the technical field of camera devices, and in particular to a camera module and electronic equipment. Background Art

[0002] With the rapid development of electronic devices such as smartphones, tablets, and e-readers, lens modules in electronic devices also tend to be diversified in design to meet different shooting needs. Some electronic devices are equipped with periscope camera modules to obtain higher optical magnification shooting effects.

[0003] In the related art, a periscope camera module usually uses a 45° prism reflection method to deflect the light collected by the lens by 90° so that it is incident on the image sensor.

[0004] However, in related technologies, in order to obtain a good focusing effect, a large number of lenses need to be configured in the lens, so a larger motor is required to drive the lens, resulting in a larger overall size of the lens, which is not conducive to the overall miniaturization of the camera module. Summary of the Invention

[0005] The embodiments of the present application provide a camera module and an electronic device to solve the problem of how to improve focusing effect while achieving miniaturization.

[0006] In one aspect, the present application provides a camera module, comprising:

[0007] a base having a mounting slot;

[0008] A lens, comprising a lens assembly and equipped with a motor for moving the lens assembly for focusing, the motor comprising a housing and a driving unit, the housing forming a receiving space, the driving unit connected to the lens assembly and both disposed within the receiving space;

[0009] an image acquisition module, connected side by side with the housing to a side of the base where the mounting slot is provided; and

[0010] The prism includes a first reflecting surface and a second reflecting surface, wherein the first reflecting surface is inclined to the optical axis of the lens, and the second reflecting surface is inclined to the axis of the image acquisition module. The prism is disposed in the mounting groove and is configured so that the light collected by the lens assembly can be reflected in sequence by the first reflecting surface and the second reflecting surface and incident on the image acquisition module. The prism includes a refractive portion, which is located on the optical path of the light collected by the lens assembly and incident on the image acquisition module, and is used to refract the light passing through the refractive portion.

[0011] In the above-mentioned camera module, the image acquisition module and the housing are arranged side by side on the same side of the prism. There is a height difference between the housing and the image acquisition module, so that the entire camera module forms a step-like shape on the mounting surface side, which is convenient for assembling the camera module to the electronic device. The lens assembly protrudes from the back of the housing of the electronic device, reducing the stacking size in the thickness direction of the electronic device, which is conducive to the lightweight and thinning of the electronic device. At the same time, the prism can not only use the reflection effect of the first reflective surface and the second reflective surface on the light to lengthen the optical path length of the light collected by the lens assembly incident on the image acquisition module to obtain a good telephoto effect, but also use the refractive part to refract the light to coordinate the focusing effect generated by the drive unit moving the lens assembly, so as to reduce the load burden of the drive unit on the lens assembly. Then, a smaller drive unit can be configured to meet the focusing needs, thereby reducing the volume of the lens, which is conducive to the overall miniaturization of the camera module.

[0012] On the other hand, the present application provides an electronic device, including a shell, a decorative piece and the above-mentioned camera module, wherein the decorative piece is connected to the shell and protrudes from the back of the shell, and the decorative piece has a groove connected to the space enclosed by the shell. The base of the camera module is arranged in the space enclosed by the shell, the image acquisition module of the camera module is located between the shell and the base, and part of the structure of the shell is accommodated in the groove.

[0013] The above-mentioned electronic device, based on utilizing the above-mentioned camera module to improve the focusing effect and achieve miniaturization, further utilizes the groove of the decorative part to accommodate the shell of the camera module, so as to reduce the stacking thickness at the location of the decorative part, so as to maintain the lightness and thinness of the electronic device while reducing the protruding height of the decorative part from the back of the shell, so as to enhance the overall aesthetics of the electronic device.

[0038] (5) Conventional laptop and / or palmtop radiotelephone transceivers, etc.

[0039] See Figure 1 , Figure 1: This is a rear view schematic diagram of an electronic device 10 in one embodiment, that is, a structural schematic diagram when viewed from the back of the electronic device 10. The electronic device 10 includes a housing 11, and the space enclosed by the housing 11 is used to arrange components of the electronic device 10 such as a camera module 20, a mainboard (not shown), and a battery (not shown). The mainboard can integrate the processor, power management module, storage unit, and baseband chip of the electronic device 10. It is understood that the electronic device 10 in the embodiments of the present application includes but is not limited to terminal devices such as mobile phones and tablet computers or other portable electronic devices.

[0040] In some embodiments, the housing 11 is provided with a light-transmitting portion 111. This light-transmitting portion 111 can be a light inlet extending through the housing 11, or can be a structural member such as glass or light-transmitting plastic. Taking the housing 11 provided with a light inlet as an example, the camera module 20 is disposed within the space enclosed by the housing 11, and the lens 22 of the camera module 20 is positioned corresponding to the light inlet, thereby allowing light from outside the electronic device 10 to enter the lens 22, thereby meeting the imaging needs of the camera module 20.

[0041] Combine Figure 2 and Figure 3 As shown, the camera module 20 includes a base 21, a lens 22, an image acquisition module 23, and a prism 24. The base 21 serves as a carrier for mounting the lens 22, image acquisition module 23, and prism 24. It is important to note that after the lens 22, image acquisition module 23, and prism 24 are mounted and fixed via the carrier, the prism 24 is positioned in the optical path between the lens 22 and the image acquisition module 23, redirecting light through reflection.

[0042] The base 21 has a mounting slot 21b for mounting a prism 24. The lens 22 and the image acquisition module 23 are mounted side by side on the base 21, so that the lens 22 and the image acquisition module 23 are located on the same side of the prism 24. The prism 24 is configured to reflect light collected by the lens 22 toward the image acquisition module 23.

[0043] Continue to combine Figure 2 and Figure 3 As shown, the lens 22 is equipped with a motor 222 for moving the lens assembly 221 for focusing. The motor 222 includes a housing 2221 and a driving portion 2222. The driving portion 2222 is connected to the lens assembly 221 and is used to drive the lens assembly 221 to move relative to the housing 2221 along the optical axis to adjust the movement distance of the lens assembly 221 along its optical axis, thereby achieving focusing.

[0044] Because the prism 24 in the optical path between the lens 22 and the image acquisition module 23 reflects, adjusts, and extends the optical path, the motor 222 in the lens 22 drives the lens assembly 221 to move for focusing, enabling the camera module 20 to achieve good telephoto imaging. The motor 222 includes, but is not limited to, a voice coil motor.

[0045] The lens assembly 221 may include one or more lenses 221a with optical power. The lens 22 can collect incident light and adjust the light to improve the imaging quality of the camera module 20.

[0046] The housing 2221 is formed with a receiving space A. Figure 2 and Figure 3 As shown, in some embodiments, the housing 2221 serves as a carrier for mounting the lens assembly 221 and the driving unit 2222 of the motor 222. The housing 2221 encloses a receiving space A to accommodate the driving unit 2222 and the lens assembly 221, and provides space for the driving unit 222 to drive the lens assembly 2221 to move along the optical axis.

[0047] The image acquisition module 23 is arranged side by side with the lens 22. Specifically, the image acquisition module 23 and the housing 2221 are both connected to the side of the base 21 where the mounting slot 21b is provided. The image acquisition module 23 and the housing 2221 are arranged side by side. Since the driving part 2222 of the motor 222 and the lens assembly 221 are located in the receiving space A, the image acquisition module 23 and the housing 2221 are arranged side by side on the same side of the prism 24. Figure 2 As shown, because the size of the lens assembly 221 along the optical axis is greater than the height of the image acquisition module 23, there is a height difference between the housing 2221 and the image acquisition module 23. As a result, the entire camera module 20 forms a stepped shape on the same side of the base 21, which facilitates assembly of the camera module 20 to the electronic device 10. The lens assembly 221 protrudes from the back of the housing 11 of the electronic device 10, while the image acquisition module 23 is housed within the housing 11 of the electronic device 10. Compared to the prior art, in which the lens assembly 221 and the image acquisition module 23 are stacked in the thickness direction of the electronic device 10, the camera module 20 of the present application facilitates reducing the thickness of the electronic device 10 at the location corresponding to the image acquisition module 23, making the electronic device 10 easier to achieve overall lightweight and thinness, improving the overall appearance and portability. In addition, with this structural arrangement, the lens assembly 221 will not overlap with the image acquisition module 23 in the length or width direction of the electronic device 10, thereby reducing the internal space occupied by the electronic device 10 and facilitating the miniaturization of the electronic device 10.

[0048] Combine Figure 2 and Figure 3As shown, the prism 24 includes a first reflecting surface 24a and a second reflecting surface 24b. The first reflecting surface 24a is inclined relative to the optical axis of the lens assembly 221, and the second reflecting surface 24b is inclined relative to the axis of the image acquisition module 23. The prism 24 is disposed within the mounting slot 21b and is configured to bend the propagation path of the light collected by the lens assembly 221 by 180° so that the light is incident on the image acquisition module 23. Specifically, the light collected by the lens assembly 221 is sequentially reflected by the first reflecting surface 24a and the second reflecting surface 24b before being incident on the image acquisition module 23.

[0049] The image acquisition module 23 includes a circuit board 231 and an image sensor 232. The image sensor 232 is attached to and electrically connected to the circuit board 231. It is understood that the prism 24 is configured to reflect light collected by the lens 22 toward the image sensor 232. The circuit board 231 is connected to the mounting base 23a, thereby securing the image sensor 232 relative to the mounting base 23a. The mounting base 23a and the housing 2221 are connected to the base 21 side by side, so that the image sensor 232 and the lens assembly 221 are aligned side by side and opposite the prism 24. The light collected by the lens assembly 221 is deflected 180° by the prism 24 to enter the image sensor 232. The image sensor 232 includes, but is not limited to, a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS) sensor.

[0050] It should be noted that the axis of the image acquisition module 23 can be understood as the perpendicular midline of the photosensitive surface of the image sensor 232. This makes it easier to align and assemble the lens assembly 221, prism 24, and image acquisition module 23, improving assembly accuracy and further reducing the size of the camera module 20 in the thickness direction of the electronic device 10.

[0051] Continue to combine Figure 2 and Figure 3 As shown, the prism 24 includes a refractive portion 24d, which is located on the optical path of the light collected by the lens assembly 221 and incident on the image acquisition module 23, and is used to refract the light passing through the refractive portion 24d. Figure 4 and Figure 5As shown, the prism 24 can not only utilize the reflection effect of the first reflecting surface 24a and the second reflecting surface 24b on the light to lengthen the optical path length of the light collected by the lens assembly 221 and incident on the image acquisition module 23 to obtain a good telephoto effect, but also can utilize the refractive portion 24d to refract the light to coordinate the focusing effect produced by the driving portion 2222 moving the lens assembly 221, so as to reduce the load burden of the driving portion 2222 on the lens assembly 221, and then a smaller driving portion 2222 can be configured to meet the focusing needs, so as to reduce the volume of the lens 22, thereby facilitating the overall miniaturization of the camera module 20.

[0052] like Figure 4 and Figure 5 As shown, the refractive portion 24d can be formed on the surface of the prism 24 that faces the lens assembly 221. Furthermore, the prism 24 has a translucent surface 24c, and the first and second reflective surfaces 24a and 24b are both inclined at an acute angle relative to the translucent surface 24c. This allows light entering the prism 24 to be incident on the first reflective surface 24a. Simultaneously, after the first reflective surface 24a reflects the light to the second reflective surface 24b, the light is then emitted from the translucent surface 24c to the image acquisition module 23 to meet imaging requirements. In this embodiment, the lens 22 and the image acquisition module 23 are both positioned toward the translucent surface 24c, and the refractive portion 24d is formed on the translucent surface 24c. This allows light to be refracted when it passes through the translucent surface 24c, where the refractive portion 24d is formed, to meet focal length adaptation requirements.

[0053] Combine Figure 6 As shown, in an embodiment in which the refractive portion 24d is formed on the surface of the prism 24 facing the image acquisition module 23, the optical axis of the refractive portion 24d is coaxial with the optical axis of the image acquisition module 23, so that the light passing through the refractive portion 24d enters the image acquisition module 23 along the optical axis of the image acquisition module 23, thereby obtaining a good imaging effect.

[0054] At least one of the first reflective surface 24 a and the second reflective surface 24 b is provided with a light absorbing material layer, and the light absorbing material layer is used to absorb stray light in the light path between the lens assembly 221 and the image acquisition module 23 .

[0055] For ease of understanding, the following description of the camera module 20 will be based on an example in which both the first light-reflecting surface 24a and the second light-reflecting surface 24b are provided with a light-absorbing material layer. Hereinafter, the light-absorbing material layer provided on the first light-reflecting surface 24a is referred to as the "first light-absorbing element 243," and the light-absorbing material layer provided on the second light-reflecting surface 24b is referred to as the "second light-absorbing element 244."

[0056] The first light absorbing element 243 is annular and encloses a first light reflecting area on the first light reflecting surface 24a. The second light absorbing element 244 is annular and encloses a second light reflecting area on the second light reflecting surface 24b. Thus, while the first and second light absorbing elements 243 and 244 absorb stray light, the first and second light reflecting areas can still reflect light.

[0057] In one embodiment, the first reflective surface 24a and the second reflective surface 24b may be coated with a reflective film layer to enhance the light reflection effect of the first reflective surface 24a and the second reflective surface 24b, thereby improving the light utilization rate of the camera module 20, thereby facilitating improved imaging brightness and imaging quality of the camera module 20. The reflective film layer may be an anti-reflection film for increasing the reflectivity of the reflective surface of the prism 24.

[0058] The first reflective surface 24 a is provided with a first anti-reflection film 245 , which covers the first reflective area. The first anti-reflection film 245 improves the reflectivity of light incident on the first reflective area, thereby increasing the amount of light entering the image sensor 232 .

[0059] The second reflective surface 24 b is provided with a second anti-reflection film 246 , which covers the second reflective area. The second anti-reflection film 246 improves the reflectivity of light incident on the second reflective area, thereby increasing the amount of light entering the image sensor 232 .

[0060] The first light absorbing member 243 and the second light absorbing member 244 can be formed on the prism 24 by screen printing or spin coating, or by coating.

[0061] Combine Figure 7 As shown, the light-transmitting surface 24 c has a convex spherical surface, and a refractive portion 24 d is formed at the position of the convex spherical surface. In this way, the refractive portion 24 d can have a focusing effect on the light passing through it.

[0062] Combine Figure 8 and Figure 9 As shown, the light-transmitting surface 24 c has a concave spherical surface, and a refractive portion 24 d is formed at the position of the concave spherical surface. In this way, the refractive portion 24 d can have a dioptric effect on the light passing through it.

[0063] It should be noted that the refractive portion 24d can be formed on the surface of the prism 24 facing the lens 22, and the housing 2221 has a light-transmitting hole 22a that communicates with the receiving space A. The light-transmitting hole 22a can allow light collected by the lens assembly 221 to enter the prism 24. Furthermore, in an embodiment in which the refractive portion 24d is formed on the surface of the prism 24 facing the lens 22, at least a portion of the structure of the refractive portion 24d is received by the light-transmitting hole 22a, and the optical axis of the refractive portion 24d is coaxial with the optical axis of the lens 22. In this embodiment, the use of the light-transmitting hole 22a to receive the refractive portion 24d makes the assembly between the prism 24 and the lens 22 more compact, thereby making the camera module 20 more compact and achieving a miniaturized design.

[0064] In some embodiments, the refractive portion 24 d may also be formed on the surface of the prism 24 facing the image acquisition module 23 .

[0065] It should be noted that there are many possibilities for the number and location of the refractive portion 24d. Figure 10 As shown, the surface of the prism 24 facing the lens 22 and the surface of the prism 24 facing the image acquisition module 23 are both formed with a refractive portion 24d, one of the refractive portions 24d is coaxial with the optical axis of the lens 22, and the other refractive portion 24d is coaxial with the optical axis of the image acquisition module 23.

[0066] See again Figure 2 and Figure 3 As shown, the prism 24 includes a first prism 241 and a second prism 242. The first prism 241 and the second prism 242 are both configured to reflect light once. It should be noted that the first reflective surface 24a is located on the first prism 241, and the second reflective surface 24b is located on the second prism 242. The light-incoming side of the first prism 241 is arranged corresponding to the light-incoming side of the second prism 242, and the light-outgoing side of the second prism 242 is arranged corresponding to the image sensor 232. After the outgoing light of the lens assembly 221 hits the first prism 241, it is reflected by the first prism 241 and hits the second prism 242, and then reflected by the second prism 242 and hits the image sensor 232.

[0067] Furthermore, in one embodiment, the first reflecting surface 24a forms a 45° angle with the optical axis of the lens assembly 221, the first reflecting surface 24a and the second reflecting surface 24b are perpendicular to each other, and the second reflecting surface 24b forms a 45° angle with the axis of the image sensor 232. Thus, the first reflecting surface 24a and the second reflecting surface 24b can each deflect the light path by 90°, thereby enabling the prism 24 to deflect the light path by 180°, so that light entering the prism 24 can be emitted from the prism 24 in a direction parallel to the incident direction and then strike the image sensor 232.

[0068] Continue to combine Figure 2 and Figure 3 As shown, in some embodiments, the mounting groove 21b has a first groove wall 21b1 and a second groove wall 21b2 that are relatively inclined, and the first prism 241 and the second prism 242 are respectively fitted with the first groove wall 21b1 and the second groove wall 21b2.

[0069] In one embodiment, the first prism 241 and the second prism 242 are both rectangular prisms. Each of the first prism 241 and the second prism 242 includes two rectangular surfaces and one inclined surface. One of the rectangular surfaces of the first prism 241 is disposed toward the lens assembly 221, and one of the rectangular surfaces of the second prism 242 is disposed toward the image sensor 232. The other rectangular surface of the first prism 241 is disposed opposite the other rectangular surface of the second prism 242. The inclined surface of the first prism 241 forms a first light reflecting surface 24a, and the inclined surface of the second prism 242 forms a second light reflecting surface 24b.

[0070] It should be noted that the first prism 241 and the second prism 242 are arranged side by side, forming a light-transmitting surface 24c facing the lens assembly 221 and the image acquisition module 23. It is understood that the refractive portion 24d is formed on the light-transmitting surface 24c. The prism 24 is configured such that light passes through the lens assembly 221 along the optical axis and is emitted to the first light-reflecting surface 24a. The first light-reflecting surface 24a reflects the light to the second light-reflecting surface 24b. The light is then reflected by the second light-reflecting surface 24b out of the light-transmitting surface 24c and enters the image sensor 232.

[0071] It is understandable that the first prism 241 and the second prism 242 may be an integral structure, that is, the two are connected as one body, and the prism 24 is a whole.

[0072] Continue to combine Figure 2 and Figure 3 As shown, the housing 2221 is sealed to the base 21. Thus, the prism 24 disposed in the mounting groove 21b is in a sealed environment, thereby preventing light leakage that would otherwise cause stray light to enter the image acquisition module 23 through the prism 24. Therefore, the camera module 20 of the present application can reduce the interference of stray light on imaging, thereby improving imaging quality.

[0073] The base 21 has a mounting surface 21a, and the mounting groove 21b has a notch extending through the mounting surface 21a. This allows the prism 24 to be installed into the mounting groove 21b through the notch. The mounting groove 21b accommodates the prism 24 so that the prism 24 does not protrude from the mounting surface 21a. Therefore, when the housing 2221 is sealed to the base 21, the mounting surface 21a can be used to improve the fit between the base 21 and the housing 2221. This not only facilitates the seal between the base 21 and the housing 2221, but also makes the overall stacking of the camera module 20 compact, thereby facilitating the miniaturization of the camera module 20.

[0074] It should be noted that adhesive members 26 are provided around the notch of the mounting surface 21 a , and the housing 2221 is sealedly connected to the base 21 via the adhesive members 26 .

[0075] The adhesive member 26 can be formed by curing the glue connecting the housing 2221 and the base 21, or it can be a double-sided tape. For example, when using glue to connect the housing 2221 and the base 21, the glue can be first applied to one of the housing 2221 and the base 21, and then the surfaces to be connected are brought together to squeeze the glue apart and prevent the formation of air holes. This can maintain good structural stability, making it difficult for the lens 22 to fall off the base 21. At the same time, the adhesive member 26 formed by the cured glue can also provide a dust and water-proof effect, extending the service life of the camera module 20.

[0076] The image acquisition module 23 is sealedly connected to the base 21 , and the image acquisition module 23 is sealedly connected to the housing 2221 , so as to further enhance the sealing effect of the mounting groove 21 b where the prism 24 is located.

[0077] It should be noted that the image acquisition module 23 and the housing 2221 can be sealed by a sealant. The image acquisition module 23 and the housing 2221 can share a joint 26 with the base 21 for sealing. In some embodiments, the image acquisition module 23 and the housing 2221 can be sealed with the base 21 using different structures. For example, in combination Figure 8 As shown, the housing 2221 and the base 21 are sealed by a first sealing member 261, and the image acquisition module 23 and the base 21 are sealed by a second sealing member 262. If there is a gap between the image acquisition module 23 and the housing 2221, the gap between the two can be sealed with a sealant.

[0078] Combine Figure 2 and Figure 11As shown, the electronic device 10 can be provided with a decorative piece 12 at the position corresponding to the lens 22 to enhance the decorative effect of this position. Specifically, the decorative piece 12 is connected to the housing 11 and protrudes from the back of the housing 11, thereby accommodating the need for the lens 22 to be installed while meeting the need for thinness and lightness in other positions of the housing 11.

[0079] The base 21 of the camera module 20 is located within the space enclosed by the housing 11, with the image acquisition module 23 of the camera module 20 positioned between the housing 11 and the base 21. The decorative member 12 has a recess 121 that communicates with the space enclosed by the housing 11, and a portion of the outer shell 2221 is accommodated within the recess 121. Because the lens assembly 221 is located within the space enclosed by the outer shell 2221, the recess 121 of the decorative member 12 accommodates the outer shell 2221. This reduces the stacking thickness of the decorative member 12, thereby maintaining the thinness of the electronic device 10 while minimizing the protrusion of the decorative member 12 from the back of the housing 11, thereby enhancing the overall aesthetics of the electronic device 10.

[0080] Continue reading Figure 11 As shown, in some embodiments, the camera module 20 further includes a filter element 25, which is used to filter out interfering light to prevent the interfering light from reaching the image sensor 232 and affecting normal imaging. In one embodiment, the filter element 25 can be an infrared cutoff filter.

[0081] Furthermore, the filter element 25 is connected to the mounting seat 23a and is located between the image acquisition module 23 and the prism 24. In this way, the stacking of the filter element 25 in the thickness direction of the image acquisition module 23 reduces the height difference between the housing 2221 and the mounting seat 23a, so that the height difference between the housing 2221 and the mounting seat 23a is not too large. In this way, when the camera module 20 is assembled to the electronic device 10, the height of the lens assembly 221 protruding from the back of the housing 11 will not be very large, which is conducive to reducing the thickness of the decorative member 12 and preventing the decorative member 12 from being too thick and too obtrusive. Therefore, in this embodiment, when the camera module 20 is assembled to the electronic device 10, on the one hand, it is conducive to achieving a lightweight design of the electronic device 10, and at the same time, it also prevents the decorative member 12 from being too obtrusive on the back of the housing 11, so as to maintain the overall aesthetic appearance of the electronic device 10.

Although in Figure 12 In the embodiment, the touch-sensitive surface and the display panel are used as two independent components to implement input and output functions, but in some embodiments, the touch-sensitive surface and the display panel can be integrated to implement input and output functions. It is understood that the display screen can include an input unit 503 and a display unit 504.

[0087] The electronic device 10 may also include at least one sensor 505, such as a light sensor, a motion sensor, and other sensors.

The microphone, on the other hand, converts collected sound signals into electrical signals, which are received by the audio circuit 506 and converted into audio data. The audio data is then processed by the processor 508 and then transmitted to, for example, another electronic device 10 via the RF circuit 501. Alternatively, the audio data can be output to the memory 502 for further processing. The audio circuit 506 may also include an earphone jack to provide communication between an external earphone and the electronic device 10.
