Referring to fig. 1, an electronic device 10 includes a housing 11, and components of the electronic device 10, such as an image capturing module 20, a motherboard (not shown), and a battery (not shown), are disposed in a space enclosed by the housing 11. The motherboard may integrate, among other things, the processor, power management module, memory unit, and baseband chip of the electronic device 10. It is to be understood that the electronic device 10 of the present embodiment includes, but is not limited to, a terminal device such as a mobile phone, a tablet computer, or other portable electronic devices 10.

In some embodiments, the housing 11 is provided with a light-transmitting portion 10a, and the light-transmitting portion 10a may be a light-entering hole penetrating the housing 11, or may be a structural member such as glass or light-transmitting plastic. Taking the case 11 with a light inlet as an example, the camera module 20 is disposed in a space enclosed by the case 11, and the light inlet of the camera module 20 are disposed opposite to each other, so that light outside the electronic device 10 can enter the lens 22 to adapt to the imaging requirement of the camera module 20.

As shown in fig. 2 and 3, the camera module 20 includes a mounting seat 21, the mounting seat 21 is used as a mounting carrier of other structures of the camera module 20, and may be in a frame shape or in a box shape, and the mounting seat 21 can meet the requirement that light enters the camera module 20. Specifically, the mounting base 21 has a mounting cavity for setting other structural members of the camera module 20, and a light inlet 21a communicating with the mounting cavity. The light inlet 21a is used for allowing light to enter the camera module 20. When the image capturing module 20 is disposed in the electronic device 10, the light entrance 21a faces the light transmitting portion 10a, so that light outside the electronic device 10 passes through the light transmitting portion 10a and enters the image capturing module 20 through the light entrance 21 a. In some embodiments, the mount 21 includes a frame 211 and a face housing 212, the anti-shake assembly 23 is mounted in the frame 211, and the face housing 212 is connected to the frame 211 such that the overall appearance of the camera module 20 is cubic. In this embodiment, the light inlet 21a is provided in the face housing 212.

The camera module 20 includes an image sensor 22 and an anti-shake assembly 23. The image sensor 22 is connected to the mount 21. The image Sensor 22 includes, but is not limited to, a charge coupled device (Charge Coupled Device, CCD) or a complementary metal oxide semiconductor device (Complementary Metal-Oxide Semiconductor Sensor, CMOS Sensor).

The area of the image sensor 22 for receiving light for photoelectric conversion to realize imaging is referred to as a "photosensitive area". For ease of understanding, taking the imaging frame as a rectangular example, the image sensor 22 has a photosensitive area having a rectangular shape. If the camera module 20 shakes during the shooting process, the photosensitive area of the image sensor 22 will shake along the length direction and/or along the width direction, so that a virtual image may be generated when light enters the image sensor 22 for imaging. Based on this, in the image capturing module 20 provided by the present application, the anti-shake component 23 is utilized to change the propagation path of the light entering the image capturing module 20, so as to counteract the image shake of the image sensor 22, thereby achieving the anti-shake purpose.

Continuing to refer to fig. 2 and 3, an anti-shake assembly 23 is mounted within the mounting cavity of the mounting base 21. The anti-shake assembly 23 includes a light reflecting member 231, a first movable frame 232, and a second movable frame 233. The reflecting element 231 is disposed on the second movable frame 233, and the reflecting element 231 has a reflecting surface 231a opposite to the light inlet 21a (see fig. 10).

The reflecting surface 231a is for reflecting the light entering from the light inlet 21a to the image sensor 22. As shown in fig. 4 and 5, a first rolling member 234 is disposed between the first movable frame 232 and the wall of the mounting cavity, and the first rolling member 234 is used for supporting the first movable frame 232 to rotate around the first axis O1 relative to the mounting seat 21. As shown in fig. 6 to 8, the second movable frame 233 is opposite to the first movable frame 232, and a second rolling member 235 is disposed between the second movable frame 233 and the first movable frame 232, and the second rolling member 235 is used for supporting the second movable frame 233 to rotate around a second axis O2 relative to the first movable frame 232, wherein the second axis O2 is perpendicular to the first axis O1 and is parallel to two adjacent edges of the photosensitive area.

In this embodiment, the first movable frame 232 can rotate smoothly relative to the mounting base 21 by using the first rolling member 234 between the first movable frame 232 and the mounting base 21, and the second movable frame 233 can rotate smoothly relative to the first movable frame 232 by using the second rolling member 235 between the second movable frame 233 and the first movable frame 232, and since the axes (i.e. the first axis O1 and the second axis O2) of the first movable frame 232 and the second movable frame 233 when rotating are perpendicular and parallel to two adjacent side lines of the photosensitive area, respectively, the reflective element 231 provided on the second movable frame 233 can deflect around two perpendicular axes, and then when the light entering from the light inlet 21a is reflected to the image sensor 22 by the reflective surface 231a of the reflective element 231, the light incident on the photosensitive area of the image sensor 22 can move in the extending direction of the two adjacent side lines of the photosensitive area. So alright compensate the shooting field of vision that causes because of the shake when making a video recording the module 20 to reduce the module 20 in-process of making a video recording and shoot the harmful effect of effect because of the shake, promoted anti-shake effect.

The first axis O1 and the optical axis of the image sensor 22 form an angle of 45 ° with the reflecting surface 231 a. The second axis O2 is perpendicular to the optical axis of the image sensor 22. The second axis O2 is parallel to the reflective surface 231 a. With this configuration, the incident angle at which the light entering from the light inlet 21a enters the reflecting surface 231a is 45 °, so that the light can be deflected by 90 ° through the reflecting surface 231a to enter the image sensor 22. Therefore, when the image capturing module 20 is disposed on the electronic device 10, the light inlet 21a can be disposed in the thickness direction of the electronic device 10, so that the optical axis of the image sensor 22 is perpendicular to the thickness direction of the electronic device 10, and stacking of optical elements in the thickness direction of the electronic device 10 can be avoided, thereby facilitating thinning of the electronic device 10.

Referring again to fig. 3 and 4, in some embodiments, the walls of the mounting cavity are provided with a first arcuate slot 21b and a second arcuate slot (not shown). The geometric centers of the first circular arc groove 21b and the second circular arc groove are both located on the first axis O1, and are used for providing the first rolling member 234. In this embodiment, when the first movable frame 232 rotates about the first axis O1 relative to the mounting base 21, the first rolling member 234 moves in the first circular arc groove 21b and the second circular arc groove where the first rolling member is located. In this way, the first rolling member 234 can provide a rolling guiding effect by using the first arc groove 21b and the second arc groove, so as to improve the stability of the first rolling member 234 moving around the first axis O1 relative to the mounting seat 21, so that the movement of the reflective element 231 is stable, and the anti-shake effect is improved.

Further, as shown in fig. 5, the number of the first rolling members 234 is 3, and the 3 rolling members are arranged in a triangle. One of the first rolling members 234 is located on the first axis O1, and the other two first rolling members 234 are disposed in the first circular arc groove 21b and the second circular arc groove, respectively. With this structural arrangement, the first rolling member 234 located on the first axis O1 serves as a center when the first movable frame 232 rotates about the first axis O1, so that the first rolling member 234 may not roll here, and only needs to meet the requirement of supporting and rotating the first movable frame 232 at a position corresponding to the first axis O1. In addition, with this structure, three-point support is realized between the first movable frame 232 and the mounting base 21, so that the first movable frame 232 can stably rotate with the mounting base 21 under the support of the three first rolling members 234, and meanwhile, the friction contact point between the first movable frame 232 and the mounting base 21 is reduced as much as possible, so that the smoothness of the rotation of the first movable frame 232 relative to the mounting base 21 is improved.

As shown in conjunction with fig. 5 and 6, the camera module 20 further includes a first drive assembly 236 and a first reset assembly 237. The first driving assembly 236 is configured to drive the first movable frame 232 to rotate about the first axis O1 relative to the mounting base 21. When the first driving component 236 releases the driving force between the first movable frame 232 and the mounting base 21, the first reset component 237 drives the first movable frame 232 to be aligned relative to the mounting base 21, so that after the first driving component 236 is used to drive the first movable frame 232 to rotate to complete the anti-shake operation, the first reset component 237 can be used to reset the first movable frame 232.

The first drive assembly 236 includes a coil and a magnet. One of the coil and the magnet is disposed on the mounting base 21, and the other is disposed on the first movable frame 232. The coil is opposite to the magnet, so that the coil can move in the magnetic field of the magnet when the coil is electrified to drive the first movable frame 232 to rotate around the first axis O1 relative to the mounting seat 21. In this embodiment, the magnetic force direction of the coil in the magnetic field of the magnet can be achieved by controlling the current direction of the coil, and the magnetic force of the coil in the magnetic field of the magnet can be adjusted by controlling the current of the coil. In this way, the first driving component 236 can conveniently control the rotation angle of the first movable frame 232 relative to the mounting seat 21 around the first axis O1, and the structure is simple to control.

The first reset assembly 237 includes a first magnet 237a and a second magnet 237b. The first magnet 237a and the second magnet 237b are respectively disposed on the mounting base 21 and the first movable frame 232, and the first magnet 237a and the second magnet 237b attract each other. In this embodiment, the first magnet 237a and the second magnet 237b are attracted to each other to provide a return torque force for the return motion of the first movable frame 232 relative to the mounting base 21, so that the return of the first movable frame 232 can be achieved without providing an electric driving structure, and energy consumption is reduced.

For the first magnet 237a and the second magnet 237b, only the two magnets are required to attract each other, so as to drive the first movable frame 232 to be aligned. Illustratively, as shown in connection with fig. 5 and 6, one of the first and second magnets 237a, 237b is a magnet and the other is a metal sheet, such that the magnet provides power to the return motion of the first carriage 232 relative to the mounting frame by attracting the metal sheet. In this embodiment, the camera module 20 further includes a TMR sensor 238, where the TMR sensor 238 is configured to detect a magnetic force change in a magnetic field of the magnet, so as to measure a rotation angle of the first movable frame 232 about the first axis O1 relative to the mounting base 21, thereby detecting a rotation angle of the first movable frame 232 about the first axis O1. TMR sensor 238 is electrically connected to the coil of first driving component 236 through a controller, and the controller is configured to perform feedback adjustment on the current of the coil according to the rotation angle of first movable frame 232, so that first movable frame 232 precisely rotates by an angle that needs to be rotated, thereby improving anti-shake precision. Because TMR sensor 238 detects the magnetic force change caused by the rotation of the magnet when first movable frame 232 rotates around first axis O1 relative to mount pad 21, the air gap between TMR sensor 238 and the magnet will not interfere with the angle detection structure, so that the angle detection is accurate and the stability is high, therefore, the reliability of implementing closed loop control debugging by the controller by performing feedback adjustment on the current of the coil according to the rotation angle of first movable frame 232 is good.

As shown in fig. 7 and 8, the camera module 20 further includes a second driving assembly 239 and a second reset assembly 240. The second driving component 239 is configured to drive the second movable frame 233 to rotate about the second axis O2 relative to the mounting base 21, and when the second driving component 239 releases the driving force between the second movable frame 233 and the mounting base 21, the second reset component 240 drives the second movable frame 233 to return relative to the mounting base 21. As for the structure of the second driving assembly 239 and the second reset assembly 240, reference may be made specifically to the first driving assembly 236 and the second reset assembly 240. For example, the second drive assembly 239 is identical in structure to the first drive assembly 236, and the first reset assembly 237 is identical in structure to the second reset assembly 240.

The reflecting element 231 includes, but is not limited to, a plane mirror or a rectangular prism, and it should be noted that, when the reflecting element 231 is a rectangular prism, the reflecting surface 231a is a slope of the rectangular prism.

For ease of understanding, as shown in fig. 9 and 10, a cartesian coordinate system is established with the first axis O1, the second axis O2, and the optical axis direction of the image sensor 22, where the first axis O1 is the Z axis, the second axis O2 is the X axis, and the optical axis direction of the image sensor 22 is the Y axis. Since the optical axis direction of the image sensor 22 is the normal direction of the light sensing surface of the image sensor 22, that is, the Y axis is perpendicular to the light sensing surface of the image sensor 22, the image sensor 22 is located in the X-Z plane. In this way, the first movable frame 232 rotates around the first axis O1 (i.e. rotates around the Z axis), and the reflecting surface 231a can deflect the light incident on the image sensor 22 in the X axis direction, so as to realize anti-shake of the image sensor 22 corresponding to the X axis direction. Accordingly, the second movable frame 233 rotates around the second axis O2 (i.e., rotates around the X-axis), and the reflecting surface 231a can deflect the light incident on the image sensor 22 in the Z-axis direction, so as to realize anti-shake of the image sensor 22 corresponding to the Z-axis direction.

In some embodiments, as shown in connection with fig. 11, the camera module 20 further includes a focusing assembly 24 disposed within the mounting cavity, the focusing assembly 24 being disposed between the reflective surface 231a and the image sensor 22. Focusing functions of the camera module 20 may be implemented using the focusing assembly 24.

The focusing assembly 24 includes a holder 241, a lens 242, and a third driving assembly 243. The lens 242 is provided on the holder 241, the optical axis of the lens 242 coincides with the optical axis of the image sensor 22, and the holder 241 is slidably connected to the mount 21. In this embodiment, the bracket 241 drives the lens 242 to move along the optical axis of the lens 242 to approach or depart from the image sensor 22 under the driving of the third driving component 243, so as to realize the optical focusing of the image capturing module 20. It should be noted that the structure of the third driving assembly 243 may be the same as that of the first driving assembly 236. As shown in fig. 12 and 13, the third driving assembly 243 includes one or more sets of coils and magnets correspondingly disposed, and the energized coils are utilized to move in the magnetic field of the magnets to realize the sliding of the bracket 241 relative to the mounting base 21, so that the lens 242 mounted on the bracket 241 moves relative to the mounting base 21. The coil is matched with the magnet to drive the structure simply and is convenient to control.

It should be noted that, the sliding structure between the bracket 241 and the mounting seat 21 has a plurality of possibilities. For example, the bracket 241 is slidably connected to the mount 21 by a slide rail.

As shown in fig. 13, the camera module 20 includes a plurality of third rolling members 244, where the plurality of third rolling members 244 are disposed between the bracket 241 and the mount 21, and are used to support the bracket 241 to slide along the optical axis of the lens 242 relative to the mount 21. In this embodiment, the third rolling member 244 is used to realize sliding fit between the bracket 241 and the mounting seat 21, so that the bracket 241 can slide smoothly relative to the mounting seat 21, and jamming of the bracket 241 during movement relative to the mounting seat 21 is avoided, so that the lens 242 disposed on the bracket 241 can move stably, and a focusing effect is ensured. It should be noted that, the mounting base 21 may be correspondingly provided with a guide groove 21c, and the extending direction of the guide groove 21c is parallel to the optical axis direction of the lens 242, so that the guide groove 21c may be used to guide the third rolling member 244 to roll, thereby improving the stability of the support 241 when sliding along the optical axis of the lens 242 relative to the mounting base 21.

In the embodiment of the present application, the first rolling member 234, the second rolling member 235, and the third rolling member 244 are only required to be able to accommodate the sliding needs of the respective structures. The first rolling member 234, the second rolling member 235, and the third rolling member 244 may have the same structure. For example, the first rolling member 234, the second rolling member 235, and the third rolling member 244 are all spherical balls. In some embodiments, the structure of the second rolling member 235 and the third rolling member 244 is different from the structure of the first rolling member 234. For example, the first rolling member 234 is a spherical ball, and the second rolling member 235 and the third rolling member 244 are cylindrical balls.
