[0035] Please refer to Figures 1-2 The first aspect of the present application provides a camera module, which can be used in smart terminals such as smartphones, tablets and the like, as a built-in camera of the smart terminal.

[0036] It can be understood that, in the following, in order to facilitate description, the camera module is defined to have a first direction Z, a second direction X and a third direction Y, which are different from each other. Exemplarily, the first direction Z can be the height direction of the camera module, the second direction X can be the length direction of the camera module, and the third direction Y can be the width direction of the camera module, the third direction Y being perpendicular to the first direction Z and the second direction X, and the second direction X being perpendicular to the first direction Z. In other embodiments, the coordinate system of the camera module can be flexibly set according to specific actual needs.

[0037] The camera module includes a base 1, a prism 2, a lens assembly 3 and an image sensor assembly 4. The base 1 includes a first support 11 and a second support 12 mounted on the first support 11, the second support 12 mainly functions to accommodate the prism 2, and has a top opening 121. The prism 2 is installed inside the second support 12, and its main optical surface 21 is exposed towards the top opening 121, while the first support 11 is used to fix the lens assembly 3 and the image sensor assembly 4. The first support forms a downwardly recessed mounting area on one side of the top opening 121, and a connecting surface on the other side, and the image sensor assembly 4 is mounted on one side of the connecting surface.

[0038] The main optical surface 21 of the prism 2 includes an incident surface 22 and an exit surface 23. The incident surface 22 is arranged to face the lens assembly 3, and the exit surface 23 is arranged to face the image sensor assembly 4. Light enters the camera module, passes through the lens assembly 3, enters the incident surface 22 of the prism 2, and is reflected multiple times inside the prism 2, and finally exits from the exit surface 23 of the prism 2 and is accurately projected onto the image sensor assembly 4, thereby achieving clear imaging.

[0039] Optionally, the fixing mode of the prism 2 can adopt glue sticking, buckling or other structure-stable fixing modes to ensure the accurate alignment and stability of the optical element. In the assembly process, the second support 12 is assembled with the prism 2 first, and then the whole is assembled into the first support 11, and then glue is supplemented at the connecting area to increase the gluing strength.

[0040] The lens assembly 3 comprises a lens module 31, a focusing driving mechanism 33 and an anti-shake driving mechanism 35. The focusing driving mechanism 33 and the anti-shake driving mechanism 35 are arranged in the mounting area to realize the sinking installation of the driving mechanisms and reduce the overall shoulder height of the camera module. The lens module 31 comprises a first lens 311 and a second lens 312 arranged in sequence along a first direction Z. The focusing driving mechanism 33 is used to drive the second lens 312 to move along the first direction Z to approach or move away from the first lens 311, thereby realizing the focusing function. The anti-shake driving mechanism 35 is used to drive the first lens 311 and the second lens 312 to move along a second direction X and a third direction Y to compensate for the shaking deviation and improve the imaging stability.

[0041] In this embodiment, as shown in Figures 1-3 The lens assembly 3 comprises a third support 32 arranged on the first support 11, a focusing circuit board 331 arranged in the third support 32, and a lens carrier 38 used to carry the second lens 312. The lens carrier 38 is movably mounted at the middle part of the third support 32 and is used to support and adjust the position of the second lens 312. The focusing driving mechanism 33 comprises a focusing coil 333 and a focusing magnetic piece 332. The focusing coil 333 faces the focusing magnetic piece 332 and is connected to the focusing circuit board 331. The focusing circuit board 331 is electrically connected to the focusing coil 333 and is used to pass current into the focusing coil 333 to make the focusing magnetic piece 332 and the focusing coil 333 have electromagnetic action, thereby driving the lens carrier 38 to move the second lens 312 along the first direction Z to realize focusing adjustment.

[0042] Specifically, the lens assembly further comprises the lens carrier 38 arranged in the third support 32 and the lens support 39 arranged on the third support 32, and the first lens 311 is fixed on the lens support 39. The lens carrier 38 comprises a first carrier 381 and a second carrier 382 arranged at an angle with the first carrier 381, and the focusing magnetic piece 332 is arranged on the second carrier 382. The second carrier 382 is provided with a first groove 383, and the third support 32 is provided with a second groove 322 at a position corresponding to the first groove 383, and the first groove 383 and the second groove 322 are provided with a ball therebetween. In this embodiment, the angle between the first carrier 381 and the second carrier 382 is 90°.

[0043] In the focusing process, the third support 32, the focusing coil 333 and the focusing circuit board 331 are focusing stators, and the lens carrier 38 and the focusing magnetic element 332 are focusing movers. When current passes through the focusing coil 333, the focusing magnetic element 332 and the focusing coil 333 have electromagnetic interaction, and according to the left-hand rule, a driving force is generated in the first direction Z, so that the focusing movers move relative to the focusing stators in the first direction Z, thereby driving the second lens 312 to move in the first direction Z to approach or move away from the first lens 311, thereby completing the focusing process. When the lens carrier 38 moves in the first direction Z, the rolling balls form a rolling guide between the first groove 383 and the second groove 322, so that the lens carrier 38 smoothly slides along the predetermined track, avoids movement deviation, and improves the reliability of the focusing system. In addition, the rolling balls can effectively reduce the friction of the lens carrier 38 during movement, improve the focusing accuracy and stability, and reduce energy loss, so that the focusing response is more sensitive.

[0044] As shown in Figure 9 The focusing circuit board 331 includes a hard board portion 334 and a soft board portion 335, and the soft board portion 335 includes a bending portion 336. The bending portion 336 includes a first bending portion 337 connected to the hard board portion 334, the first bending portion 337 is bent by 90° in the third direction Y to form a second bending portion 338, and the second bending portion 338 is bent by 90° in the first direction Z to form a third bending portion 339. Alternatively, the soft board portion 335 is a flexible circuit board. When the third support 32 moves in the second direction X or the third direction Y under the driving of the anti-shake driving mechanism 35, the hard board portion 334 moves with the third support 32, and the bending portion 336 deforms to adapt to the movement of the third support 32, thereby ensuring stable electrical connection of the focusing circuit board 331 during movement.

[0045] In this embodiment, the lens assembly 3 includes a fourth support 34 arranged on the first support 11, and an anti-shake circuit board 351 arranged between the fourth support 34 and the first support 11. The anti-shake driving mechanism 35 includes a first anti-shake coil 353 and a second anti-shake coil 355 arranged on the fourth support 34, and a first anti-shake magnetic element 352 and a second anti-shake magnetic element 354 arranged on the third support 32. The anti-shake circuit board 351 is electrically connected to the first anti-shake coil 353 and the second anti-shake coil 355 through the lead terminals, and is used to pass current to the coils to control the magnetic field change of the first anti-shake magnetic element 352 and the second anti-shake magnetic element 354, thereby achieving stable adjustment of the lens assembly 3.

[0046] Specifically, as shown in Figure 4As shown, the lens assembly 3 further comprises a guide bracket 37, a plurality of first connecting members (not shown) and a plurality of second connecting members (not shown). The guide bracket 37 is disposed between the third bracket 32 and the fourth bracket 34, and movably connects the third bracket 32 through the plurality of first connecting members and movably connects the fourth bracket 34 through the plurality of second connecting members.

[0047] The third bracket 32 is provided with a plurality of first grooves 321 on one side close to the guide bracket 37, the guide bracket 37 is provided with a plurality of second grooves 371 and a plurality of third grooves 372 on two ends respectively, and the fourth bracket 34 is provided with a plurality of fourth grooves 341 on one side close to the guide bracket 37. The plurality of first connecting members are at least partially located in the first grooves 321 and at least partially located in the second grooves 371, and the plurality of second connecting members are at least partially located in the fourth grooves 341 and at least partially located in the third grooves 372, wherein the axes of the first grooves 321 and the third grooves 372 are perpendicular to each other.

[0048] When the camera module is subjected to anti-shake along the second direction X, the fourth bracket 34 and the first anti-shake coil 353 are the anti-shake stator, and the third bracket 32, the guide bracket 37 and the first anti-shake magnetic member 352 are the anti-shake rotor. When the camera module is subjected to anti-shake along the third direction Y, the fourth bracket 34, the guide bracket 37 and the second anti-shake coil 355 are the anti-shake stator, and the third bracket 32 and the second anti-shake magnetic member 354 are the anti-shake rotor. In the above process, the anti-shake rotor is driven by the magnetic field force to drive the first lens 311 and the second lens 312 to move relative to the anti-shake stator along the second direction X or the third direction Y to compensate for the shaking deviation.

[0049] Optionally, the first connecting members and the second connecting members can be balls, which can effectively reduce the frictional resistance between the components, improve the response speed and accuracy of focusing and anti-shake, ensure the smoothness of the movement of the lens assembly 3, and are particularly suitable for high-precision automatic focusing and optical anti-shake scenes.

[0050] Optionally, the first connecting members and the second connecting members can be micro sliding rails or linear sliding blocks, which can make the third bracket 32 move smoothly along a predetermined track, improve the accuracy of focusing and anti-shake, and reduce friction loss.

[0051] In the embodiment, as shown, Figure 5 The first anti-shake coil 353 and the first anti-shake magnetic member 352 are stacked along the first direction Z, the second anti-shake coil 355 and the second anti-shake magnetic member 354 are stacked along the first direction Z, and the first anti-shake coil 353 and the second anti-shake coil 355 are respectively located on two sides adjacent to the fourth bracket 34.

[0052] When the anti-shake circuit board 351 passes current to the first anti-shake coil 353, electromagnetic interaction with the first anti-shake magnetic member 352 generates a driving force in the second direction X according to the left-hand rule, which in turn drives the third support 32 and the guide support 37 to drive the first lens 311 and the second lens 312 to move in the second direction X to compensate for device jitter. Similarly, when the anti-shake circuit board 351 passes current to the second anti-shake coil 355, electromagnetic interaction with the second anti-shake magnetic member 354 will generate a driving force in the third direction Y, which in turn drives the third support 32 to drive the first lens 311 and the second lens 312 to move in the third direction Y to further compensate for jitter deviation and improve imaging stability, thereby improving the anti-shake performance of the camera module, especially suitable for long-stroke scenarios such as handheld shooting and long-focus imaging.

[0053] In an embodiment, as shown in Figure 6 , the first anti-shake coil 353 and the first anti-shake magnetic member 352 are stacked along the second direction X, and the second anti-shake coil 355 and the second anti-shake magnetic member 354 are stacked along the third direction Y.

[0054] When the anti-shake circuit board 351 passes current to the first anti-shake coil 353, magnetic interaction between the first anti-shake coil 353 and the first anti-shake magnetic member 352 generates a driving force in the second direction X, which in turn drives the third support 32 to drive the first lens 311 and the second lens 312 to move in the second direction X to compensate for device jitter. Similarly, when the anti-shake circuit board 351 passes current to the second anti-shake coil 355, magnetic interaction between the second anti-shake coil 355 and the second anti-shake magnetic member 354 generates a driving force in the third direction Y, which in turn drives the third support 32 provided with the second anti-shake magnetic member 354 to move in the third direction Y, thereby driving the first lens 311 and the second lens 312 to move in the third direction Y. In this embodiment, the anti-shake process is completed by electromagnetic thrust, which has fast response speed and can achieve more accurate micro-jitter compensation, and is suitable for short-stroke anti-shake.

[0055] Optionally, as shown in Figures 6-7 , the camera module further includes a connection lead 36 embedded in the second support 12, which is used to provide electrical signal transmission so that the electronic components of the camera module can work normally. The two ends of the connection lead 36 extend from the base 1, one end is electrically connected with the image sensor assembly 4, and the other end is electrically connected with the focusing circuit board 331 and the anti-shake circuit board 351, which is used to provide working current for the focusing drive mechanism 33 and the anti-shake drive mechanism 35, thereby realizing automatic focusing and optical anti-shake functions. The embedded mode of the connection lead 36 not only optimizes the internal wiring of the camera module and improves the stability of electrical signal transmission, but also avoids the occupation of space by additional wire harnesses, making the overall structure of the module more compact and meeting the design requirements of high integration and miniaturization.

[0056] In the embodiment, the image sensor assembly 4 comprises an image sensor and a circuit board, and the circuit board is electrically connected with the image sensor and the connecting lead 36. The circuit board is used for receiving the optical signal collected by the image sensor and processing the optical signal to output a digital signal or an analog signal for a subsequent image processing unit.

[0058] Through the structural design, the camera module can be integrated in the intelligent terminal to realize high-definition shooting, automatic focusing and optical anti-shake functions, and improve the imaging quality of the terminal device. At the same time, the power supply module is directly connected with the image sensor assembly 4 to ensure the stability of signal processing and improve the efficiency and accuracy of image acquisition.
