Description

Technical Field

[0001] The present application relates to the field of camera anti-shake technology, and in particular to a camera module and a camera device. Background Art

[0002] Cameras and other imaging devices often face the problem of camera shake affecting the quality of the shot. To address this issue, some cameras use image sensor stabilization. This involves integrating an image sensor drive motor, consisting of coils and magnets, into the camera module equipped with the image sensor. The motor drives the image sensor to vibrate, compensating for image changes caused by camera shake. A motor chip is also integrated into the camera module to control the motor's operation. However, both the image sensor and motor chip in the camera module are prone to heating during operation, leading to localized overheating and affecting the performance of the image sensor and motor chip. Utility Model Content

[0003] Based on this, it is necessary to provide a camera module and a camera device to improve the heat dissipation performance of the camera module and reduce the impact of heat generated by the image sensor and motor chip on the performance.

[0004] A camera module, comprising:

[0005] mover carrier;

[0006] An image sensor is fixedly mounted on the movable carrier;

[0007] An electromagnetic component is fixedly arranged on the mover carrier;

[0008] a first stator carrier;

[0009] a drive control element, fixedly disposed on the first stator carrier; and

[0010] A driving circuit element extends from the first stator carrier to the mover carrier and is electrically connected to the driving control element and the electromagnetic assembly.

[0011] In the aforementioned camera module, the image sensor and drive control element are disposed on the mover carrier and the first stator carrier, respectively, while the drive circuit element extends from the first stator carrier to the mover carrier. Thus, when both the electromagnetic assembly and the image sensor are disposed on the mover carrier, disposing the drive control element on the first stator carrier also enables electrical connection between the drive control element and the electromagnetic assembly via the drive circuit element, without requiring the drive control element and the image sensor to be disposed on the same carrier. This allows the heat generated by the drive control element and the image sensor to be dissipated through the first stator carrier and the mover carrier, respectively, preventing localized overheating caused by heat accumulation on the same carrier. This improves the heat dissipation performance of the camera module and reduces the impact of heat generated by the image sensor and drive control element on performance.

[0012] A camera device includes a lens and a camera module as described in any of the above embodiments, wherein the lens is located on the side of the photosensitive surface of the image sensor. Using this camera module in a camera device provides excellent heat dissipation performance, and the performance of the image sensor and drive control components is not easily affected by high temperatures, thereby improving the performance stability, service life, and image quality of the camera device.

[0033] See Figure 1 、 Figure 2 and Figure 3 As shown, Figure 1-Figure 3 They are schematic diagrams of the structures of the camera module 10 at different angles in some embodiments. The camera module 10 provided in the present application includes an image sensor 11, and the image sensor 11 has a photosensitive surface. The image sensor 11 can be used to convert the light received by the photosensitive surface into image information through photoelectric conversion, thereby realizing the image capture function. The image sensor 11 includes but is not limited to a charge-coupled device sensor (CCD) or a complementary metal oxide semiconductor sensor (CMOS). In some embodiments, the camera device further includes a filter 12, and the filter 12 includes but is not limited to an infrared cutoff filter element. The filter 12 can be provided on the image sensor 11, and the filter 12 is used to filter out interference light to prevent the interference light from being projected onto the photosensitive surface and affecting the imaging quality.

[0034] The camera module 10 provided in the present application includes but is not limited to being used in camera and other camera devices. For example, the camera module 10 can form a camera device together with a lens (not shown in the figure). The lens may include one or more lenses with optical focal length, and the lens is arranged on the side where the photosensitive surface of the image sensor 11 is located. When the camera device is used for shooting, the light reflected by the subject is adjusted by the lens and then projected onto the photosensitive surface of the image sensor 11. The camera module 10 can drive the image sensor 11 to move, for example, drive the image sensor 11 to move along the first direction and / or the second direction to compensate for the shaking of the camera device in the first direction and / or the second direction, realize the optical image stabilization function, and enable the camera device to obtain good shooting quality even when shaking. The first direction and the second direction can be two mutually perpendicular directions on a plane parallel to the photosensitive surface.

[0035] In some embodiments, the camera module 10 further includes a first stator carrier 13, a second stator carrier 14, and a mover carrier 15. The first stator carrier 13 and the second stator carrier 14 are connected to each other, the mover carrier 15 is disposed between the first stator carrier 13 and the second stator carrier 14, and the image sensor 11 is disposed on the mover carrier 15. At least one of the first stator carrier 13 and the second stator carrier 14 is configured to drive the mover carrier 15 to move, thereby driving the image sensor 11 to move. For example, one of the first stator carrier 13 and the second stator carrier 14 can generate a magnetic force with the mover carrier 15 to drive the mover carrier 15 to move in the first direction and / or the second direction. The first stator carrier 13 and the second stator carrier 14 can also generate a magnetic force with the mover carrier 15 to drive the mover carrier 15 to move, thereby driving the image sensor 11 to move and achieve optical image stabilization. Of course, in other embodiments, the second stator carrier 14 can be omitted, and the movable carrier 15 can be movably disposed on the first stator carrier 13 and can move relative to the first stator carrier 13, as long as the optical image stabilization function can be achieved. In this application, the movable carrier 15, the first stator carrier 13, and the second stator carrier 14 all include, but are not limited to, plate-like structures made of plastic.

[0036] The above-mentioned camera module 10 drives the movable subassembly to move through the first stator carrier 13 and / or the second stator carrier 14, thereby driving the image sensor 11 to move, and can integrate the shake correction module of the camera device into the image sensing module. Compared with the method of driving the lens to move to achieve optical image stabilization, it is beneficial to reduce the size and weight of the driven object of the camera module 10, thereby helping to compress the size of the driving structure in the first stator carrier 13 and / or the second stator carrier 14 and the movable subcarrier 15, and also helps to reduce the overall occupied space of the camera module 10, thereby facilitating the miniaturization design of the camera device. The movable carrier 15 is arranged between the first stator carrier 13 and the second stator carrier 14. The first stator carrier 13 and the second stator carrier 14 can jointly provide limiting and protective functions for the movable carrier 15, which can improve the overall structural strength and functional stability of the camera module 10. When the first stator carrier 13 and the second stator carrier 14 drive the movable carrier 15 to move at the same time, the driving force on the movable carrier 15 can also be increased, which is beneficial to improving the sensitivity and accuracy of anti-shake.

[0037] Combine Figure 4 and Figure 5As shown, in some embodiments, a magnetic force can be generated between the first stator carrier 13 and the mover carrier 15 to drive the mover carrier 15 to move the image sensor 11. For example, the camera module 10 also includes a first magnetic assembly 16 disposed on the stator carrier and an electromagnetic assembly 17 disposed on the mover carrier 15. The first magnetic assembly 16 is configured to drive the electromagnetic assembly 17 to move via electromagnetic force, thereby driving the mover carrier 15 to move relative to the first stator carrier 13, and the image sensor 11 to move synchronously with the mover carrier 15. The first magnetic assembly 16 may include one or more magnetic elements, including but not limited to magnets or lodestones, any suitable magnetic material capable of generating a magnetic field. The electromagnetic assembly 17 may include one or more electromagnetic elements, such as coils, that can generate a magnetic field when energized. When one or more coils in the electromagnetic assembly 17 are energized, they generate a magnetic field, which in turn generates a magnetic force with the magnetic field of the magnetic material in the first magnetic assembly 16, thereby driving the electromagnetic assembly 17 to move relative to the first magnetic assembly 16, causing the mover carrier 15 to move the image sensor 11 relative to the stator carrier.

[0038] For example, multiple magnetic elements and multiple coils are arranged one by one opposite to each other, wherein at least one group of coils and magnetic elements are arranged along the second direction and can drive the mover carrier 15 to move relative to the first stator carrier 13 along the first direction through magnetic force, and at least one other group of coils and magnetic elements are arranged along the first direction and can drive the mover carrier 15 to move relative to the first stator carrier 13 along the second direction through magnetic force.

[0039] In other embodiments, when the camera module 10 is provided with a second stator carrier 14, the camera module 10 may further include a second magnetic assembly (not shown) provided on the second stator carrier 14. The second magnetic assembly includes a plurality of magnetic elements. The magnetic elements in the first magnetic assembly 16, the coils in the electromagnetic assembly 17, and the magnetic elements in the second magnetic assembly are arranged relative to each other. The second magnetic assembly can also drive the electromagnetic assembly 17 to move through electromagnetic force to improve the sensitivity and accuracy of the image sensor 11 movement to achieve optical image stabilization. In some other embodiments, the second magnetic assembly can also be omitted. The material of the second stator carrier 14 can be a yoke material. The second stator carrier 14 is arranged to cover the electromagnetic assembly 17, so that the second stator carrier 14 can prevent the leakage of the magnetic field of the electromagnetic assembly 17 and the first magnetic assembly 16, improve the efficiency of magnetic field utilization, and thus improve the accuracy and sensitivity of the image sensor 11 movement.

[0040] Further, refer to Figure 6 and Figure 7As shown, in some embodiments, the camera module 10 further includes a drive control element 18 and a drive circuit element 19. The drive control element 18 is fixedly mounted on the first stator carrier 13. The drive circuit element 19 extends from the first stator carrier 13 to the mover carrier 15 and is electrically connected to the drive control element 18 and the electromagnetic assembly 17, enabling the drive control element 18 to power and control the coils in the electromagnetic assembly 17 through the drive circuit element 19. The drive control element 18 includes, but is not limited to, a motor chip for the camera module 10. The drive control element 18 can power and control the coils in the electromagnetic assembly 17 to control the magnetic field force generated by the electromagnetic assembly 17 and the first magnetic assembly 16, thereby driving the mover carrier 15 to move the image sensor 11 relative to the first stator carrier 13 to achieve optical image stabilization. The drive circuit element 19 is used to establish electrical and communication connections between the drive control element 18 and the electromagnetic assembly 17. The drive circuit element 19 can be entirely a flexible printed circuit board (FPC) or a rigid-flex board combining an FPC and a printed circuit board (PCB).

[0041] In the aforementioned camera module 10, the image sensor 11 and the drive control element 18 are disposed on the movable carrier 15 and the first stator carrier 13, respectively, while the drive circuit element 19 extends from the first stator carrier 13 to the movable carrier 15. Thus, when both the electromagnetic assembly 17 and the image sensor 11 are disposed on the movable carrier 15, disposing the drive control element 18 on the first stator carrier 13 also enables electrical connection between the drive control element 18 and the electromagnetic assembly 17 via the drive circuit element 19, without disposing the drive control element 18 and the image sensor 11 on the same carrier. This allows the heat generated by the drive control element 18 and the image sensor 11 to be dissipated through the first stator carrier 13 and the movable carrier 15, respectively, thereby preventing localized excessive temperatures caused by heat accumulation on the same carrier. This improves the heat dissipation performance of the camera module 10 and reduces the impact of heat generated by the image sensor 11 and the drive control element 18 on performance.

[0042] Combine Figure 7 、 Figure 8 and Figure 9As shown, in some embodiments, the camera module 10 further includes a circuit support 21, which is disposed on the first stator carrier 13, for example, fixedly disposed on a side of the first stator carrier 13 facing away from the mover carrier 15. A portion of the drive circuit element 19 is disposed on the circuit support 21. In some embodiments, the drive circuit element 19 includes a connecting circuit portion 191 and a heat conducting circuit portion 192. At least a portion of the heat conducting circuit portion 192 is disposed on and in thermal contact with the circuit support 21. The drive control element 18 is disposed on and electrically connected to the heat conducting circuit portion 192. For example, the heat conducting circuit portion 192 is disposed on a side of the circuit support 21 facing away from the first stator carrier 13. As a result, heat generated by the drive control element 18 can be conducted to the circuit support 21 through the heat conducting circuit portion 192 and dissipated to the first stator carrier 13, thereby improving the dissipation of heat generated by the drive control element 18 and enhancing the heat dissipation efficiency of the drive control element 18. The connecting line portion 191 is connected to the heat conducting line portion 192 and is bent from the first stator carrier 13 to the mover carrier 15 . For example, it is bent from the side of the first stator carrier 13 facing away from the mover carrier 15 along the circumferential side of the first stator carrier 13 to the mover carrier 15 . The connecting line portion 191 is electrically connected to the electromagnetic assembly 17 and the heat conducting line portion 192 .

[0043] In some embodiments, the driving circuit element 19 also includes a lead-out circuit portion 193, which is electrically connected to the connecting circuit portion 191 or the heat-conducting circuit portion 192 and is used to electrically connect to external components. For example, the lead-out circuit portion 193 can be a circuit structure that is led out from the heat-conducting circuit portion 192 or the connecting circuit portion 191 in the driving circuit element 19 and is used to electrically connect to the central processing unit of the camera device, so as to realize the communication connection and electrical connection between the central processing unit of the camera device and the driving control element 18.

[0044] In some embodiments, the camera module 10 further includes an image control element 22 and an image circuit element (not shown). The image control element 22 is disposed on the movable carrier 15, and the image sensor 11 is disposed on the side of the image control element 22 facing away from the movable carrier 15. The image control element 22 includes, but is not limited to, a PCB for powering and controlling the image sensor 11. The image circuit element is electrically connected to the image control element 22 and the connection circuit portion 191. In other words, the drive circuit element 19, while enabling electrical connection between external components and the drive control element 18 via the lead-out circuit portion 193, also enables electrical and communication connections between external components, such as the camera's central processing unit, and the image control element 22. This integrates the circuitry of the image sensor 11 with that of the drive control element 18, simplifying the circuitry on the movable carrier 15, reducing the space occupied by the circuitry, and improving component integration. In some embodiments, the connection circuit portion 191 is an FPC, the heat conduction circuit portion 192 is an FPC or PCB, the lead-out circuit portion 193 is an FPC, and the image circuit element is an FPC or PCB.

[0045] Combine Figure 7 、 Figure 8 and Figure 9 As shown, in some embodiments, the circuit support 21 is provided with a receiving cavity 211 extending therethrough. The drive control element 18 is disposed on a side of the heat-conducting circuit portion 192 facing the first stator carrier 13 and is at least partially located within the receiving cavity 211. The camera module 10 further includes a first heat-conducting member (not shown) that fills at least a portion of the receiving cavity 211. The first heat-conducting member includes, but is not limited to, a thermally conductive gel. The first heat-conducting member is in thermal contact with the drive control element 18 and the first stator carrier 13 within the receiving cavity 211. Thus, the first heat-conducting member can effectively conduct heat generated by the drive control element 18 to the first stator carrier 13, where it is dissipated through the first stator carrier 13, thereby improving the heat dissipation efficiency of the drive control element 18 and reducing the impact of heat on the performance and service life of the drive control element 18.

[0046] Furthermore, in some embodiments, the camera module 10 further includes a second heat conducting member 25 disposed between the circuit support 21 and the first stator carrier 13. The second heat conducting member 25 is attached to the first stator carrier 13. The orthographic projection of the second heat conducting member 25 on the circuit support 21 at least covers the receiving cavity 211. The coverage area of ​​the second heat conducting member 25 on the circuit support 21 is larger than the receiving cavity 211. The second heat conducting member 25 is in thermal contact with the first heat conducting member on the side facing the circuit support 21. The second heat conducting member 25 includes, but is not limited to, a heat-conducting graphite sheet, etc. The first heat conducting member is in thermal contact with the first stator carrier 13 via the second heat conducting member 25. The second heat conducting member 25 can quickly disperse the heat of the drive control element 18 conducted by the first heat conducting member to the first stator carrier 13, thereby further improving the heat dissipation efficiency of the drive control element 18.

[0047] In some embodiments, the camera module 10 further includes a third heat conductor 26 . The third heat conductor 26 is disposed on the side of the heat conducting circuit portion 192 facing away from the first stator carrier 13 . The projection of the third heat conductor 26 on the heat conducting circuit portion 192 at least partially overlaps with the projection of the drive control element 18 on the heat conducting circuit portion 192 . The third heat conductor 26 is configured to be in thermal contact with the housing 31 of the camera device. The third heat conductor 26 includes, but is not limited to, a thermally conductive gasket made of a material such as graphite with excellent thermal conductivity. The third heat conductor 26 can transfer some of the heat generated by the drive control element 18 on the side of the heat conducting circuit portion 192 facing away from the first stator carrier 13 to the housing 31 of the camera device for dissipation, further improving the heat dissipation efficiency of the drive control element 18 . It can be understood that the first heat conductor, the second heat conductor 25 and the third heat conductor 26 cooperate to conduct the heat generated by the drive control element 18 to the first stator carrier 13 and the housing 31 of the camera device on opposite sides of the drive control element 18, and the heat conduction circuit portion 192 can distribute the heat generated by the drive control element 18 to the circuit bracket 21. Multiple heat dissipation paths can effectively improve the heat dissipation efficiency of the drive control element 18 and reduce the impact of heat on the performance stability and service life of the drive control element 18.

[0048] Combine Figure 5 and Figure 7As shown, in some embodiments, when the camera module 10 includes the first magnetic component 16, the first stator carrier 13 is provided in a plurality of mounting slots 131 that pass through the first stator carrier 13, and the circuit bracket 21 is provided with a plurality of mounting openings 212 that pass through the circuit bracket 21. The mounting openings 212 are arranged one-to-one opposite to the mounting slots 131. The plurality of magnetic elements in the first magnetic component 16 are arranged one-to-one in the mounting slots 131, and are partially located in the mounting openings 212. Thus, while the circuit bracket 21 is provided with the heat-conducting circuit portion 192, it can also provide auxiliary fixing for the magnetic elements. That is, the bracket structure for fixing the magnetic elements and the bracket structure for supporting the heat-conducting circuit portion 192 are integrated into one, which is conducive to reducing the parts of the camera module 10, simplifying the structure of the camera module 10, and compressing the space occupied by the camera module 10.

[0049] refer to Figure 5 As shown, in some embodiments, the camera module 10 further includes a yoke structure 23, which is fixedly mounted on the side of the circuit support 21 facing away from the first stator carrier 13. The orthographic projection of the yoke structure 23 on the circuit support 21 covers at least the mounting opening 212. The yoke structure 23 can block magnetic field leakage from the magnetic element on the side of the circuit support 21 facing away from the first stator carrier 13, thereby improving magnetic field utilization efficiency and thereby enhancing the accuracy and sensitivity of the image sensor 11's anti-shake function. In some embodiments, the thermal conductive circuit portion 192 may be partially located between the yoke structure 23 and the circuit support 21. In this case, the yoke structure 23 can also serve to secure and protect the thermal conductive circuit portion 192.

[0050] See Figure 10 and Figure 11 As shown, in some embodiments, the image control element 22 is provided with a heat conducting groove 221 that passes through the image control element 22. The heat conducting groove 221 is provided corresponding to the image sensor 11. That is, when the image sensor 11 is provided on the image control element 22, the image sensor 11 covers the heat conducting groove 221. The camera module 10 also includes a fourth heat conducting member 27. The fourth heat conducting member 27 fills at least a portion of the heat conducting groove 221 and is in thermal contact with the image sensor 11 and the movable carrier 15. The fourth heat conducting member 27 includes but is not limited to a thermally conductive gel. The fourth heat conducting member 27 is provided in conjunction with the heat conducting groove 221 to form a heat conducting path from the image sensor 11 to the movable carrier 15, so that the heat generated by the image sensor 11 can be quickly and efficiently conducted to the movable carrier 15 for dissipation, thereby reducing the impact of the image control element 22 on the heat dissipation performance of the image sensor 11.

[0051] In some embodiments, the camera module 10 further includes a raised structure 222 provided on the side of the movable carrier 15 facing the image control element 22, at least a portion of the raised structure 222 is located within the heat conducting groove 221, and the fourth heat conducting member 27 fills the heat conducting groove 221 and covers the surface and side surface of the raised structure 222 facing the image sensor 11. The raised structure 222 can be integrally formed with the image control element 22, for example, it can be a structure raised on the substrate of a PCB. Providing the raised structure 222 can increase the contact area between the fourth heat conducting member 27 and the raised structure 222, thereby increasing the heat conduction efficiency between the fourth heat conducting member 27 and the movable carrier 15, which is beneficial to further improve the heat dissipation efficiency of the image sensor 11.

[0052] Combine Figure 4 、 Figure 10 and Figure 12 As shown, in some embodiments, the camera module 10 further includes a sixth flexible heat-conducting member 29, which includes but is not limited to a flexible graphite sheet. One end of the sixth flexible heat-conducting member 29 is connected to the movable carrier 15, and the other end is used for thermal contact with the housing 31 of the camera device. The sixth flexible heat-conducting member 29 can transfer the heat transferred from the image sensor 11 to the movable carrier 15 to the housing 31 of the camera device in a timely manner for heat dissipation, which is beneficial to improving the heat dissipation efficiency of the camera module 10. At the same time, by using a flexible material as the sixth flexible heat-conducting member 29, when the movable carrier 15 moves relative to the first stator carrier 13 to achieve the optical image stabilization function, the sixth flexible heat-conducting member 29 can deform or bend with the movement of the movable carrier 15, and is not easily damaged by the movement of the movable carrier 15, nor will it hinder the movement of the movable carrier 15.

[0053] Please see again Figure 2 and Figure 3 As shown, in some embodiments, the camera module 10 further includes a fifth heat conducting member 28, which includes but is not limited to a graphite sheet. The fifth heat conducting member 28 includes a first heat conducting portion 281 and a second heat conducting portion 282 connected to each other. The first heat conducting portion 281 is disposed on the side of the image control element 22 facing away from the movable carrier 15, and the second heat conducting portion 282 is disposed around the movable carrier 15. The first heat conducting portion 281 and the second heat conducting portion 282 can be an integrated structure.
