Drive assembly 320 includes a mecanum wheel 301, where mecanum wheel 301 may be coupled to an external drive motor, or where a separate drive motor may be provided for mecanum wheel 301. In the case where the mecanum wheel 301 rotates, the mecanum wheel 301 can drive the lens assembly 100 to rotate with respect to the apparatus body.

Specifically, as described above, the driving assembly 320 may be mounted on the first mounting frame 210 or the second mounting frame 220, taking the example that the driving assembly 320 is mounted on the second mounting frame 220 as an example, the driving assembly 320 and the fitting assembly 310 are both connected with the lens assembly 100, so that (the fitting portion of) the lens assembly 100 is sandwiched between the first mounting frame 210 and the second mounting frame 220, and by means of the fitting assembly 310 and the driving assembly 320 connected with the lens assembly 100, the lens assembly 100 cannot move relative to the device body along the direction of the optical axis thereof. The driving assembly 320 is connected with the lens assembly 100 and the device body in a rolling manner, and the Mecanum wheel 301 can drive the lens assembly 100 and the device body to rotate relatively by controlling the Mecanum wheel 301 to move along the direction perpendicular to the optical axis of the lens assembly 100, wherein the rotating direction is the direction around the optical axis of the lens assembly 100.

More specifically, the number of mecanum wheels 301 may be one, and one mecanum wheel 301 can power the relative movement between the lens assembly 100 and the apparatus body. Optionally, the number of the mecanum wheels 301 is two, three, or more, in this case, a plurality of mecanum wheels 301 may be uniformly and alternately arranged around the optical axis of the lens assembly 100, on one hand, a stronger driving acting force may be provided for the lens assembly 100, and on the other hand, each place on the lens assembly 100 may also be subjected to a driving acting effect, so as to improve the rotational stability of the lens assembly 100, and further prevent the lens assembly 100 from being stuck due to uneven deflection of the force in the rotating process.

The fitting component 310 may include a rolling portion such as a roller, the fitting component 310 may be installed inside or outside the lens component 100 through the first mounting frame 210 or the second mounting frame 220, and the fitting component 310 may generate a rolling motion along with the motion of the driving component 320, so that the lens component 100 can rotate around the optical axis of the lens component 100 relative to the device body. Correspondingly, the number of the fitting assemblies 310 may be one or more, and in the case that the number of the fitting assemblies 310 is more, the motion stability between the lens assembly 100 and the device body may also be improved. Alternatively, the rolling part may be a rolling ball, in which case, the reliability of the fitting between the rolling part and the lens assembly 100 may be improved, and the rolling part may be fitted to the first mounting bracket 210 or the second mounting bracket 220 by a connection member such as a ball hinge.

In another embodiment of the present application, the mating assembly 310 may also include a mecanum wheel 301, in which case the driving assembly 320 and the mating assembly 310 may be considered to be similar or identical in structure. By making the fitting component 310 also include the mecanum wheels 301, the fitting component 310 also has a driving capability, so that the driving component 310 and the driving component 320 are mutually fitted, and the stability of the relative movement between the lens component 100 and the device body is further improved.

The embodiment of the application provides a camera module, and the camera module can cooperate with an equipment body in electronic equipment. The camera module includes a lens assembly 100, a first mounting bracket 210, a second mounting bracket 220, a connecting portion 230, a fitting assembly 310, and a driving assembly 320. One of the fitting assembly 310 and the driving assembly 320 is disposed inside the lens assembly 100 and connected to the lens assembly 100, and the other is disposed outside the lens assembly 100 and connected to both the lens assembly 100 and the device body in a rolling manner, so as to restrict relative movement of the lens assembly 100 and the device body in the optical axis direction of the lens assembly 100. And, the driving assembly 320 and the mating assembly 310 can be synchronously operated by the first mounting bracket 210, the second mounting bracket 220 and the connecting part 230, the driving assembly 320 includes a mecanum wheel 301, and the lens assembly 100 and the device body can be relatively rotated in a direction around the optical axis of the lens assembly 100 by the operation of the mecanum wheel 301. In addition, by controlling the direction and amount of movement of mecanum wheel 301, the direction and amount of rotation of lens assembly 100 with respect to the apparatus body can be changed. In the process of shooting by adopting the camera module, if the camera module rotates around the optical axis direction of the camera module due to the shake of a user, the movement direction and the movement amount of the mecanum wheel 301 can be correspondingly controlled according to the rotation condition of the camera module, so that the lens assembly 100 generates the rotation action opposite to the rotation condition, the condition that the lens assembly 100 and the viewing area rotate relatively due to the shake of the user is compensated, the relative position (or the relative angle) between the viewing area of the camera module and the lens assembly 100 is kept unchanged, the image blur caused by the rotation of the camera module is prevented, and the imaging quality of the camera is high.

In addition, in the camera module disclosed in the above embodiment, an angle detection device such as a gyroscope capable of detecting the rotation condition of the lens assembly 100 may be provided, so that during shooting, the rotation condition of the lens assembly 100 around its own optical axis direction relative to (a living body or an object in) the viewing area may be measured by the angle detection device, and then, according to the rotation condition, the driving assembly 320 may be correspondingly controlled, so that the mecanum wheel 301 moves a preset distance along the preset direction, so that the driving assembly 320 drives the lens assembly 100 to rotate by a preset angle along the preset direction, thereby compensating the rotation condition of the camera module, and ensuring that the relative angle between the lens assembly 100 and the viewing area is substantially kept unchanged.

As described above, the lens assembly 100 can be driven to rotate reversely by detecting the rotation angle of the lens assembly 100 relative to its initial position, and controlling the driving assembly 320 to drive the lens assembly 100 to rotate reversely according to the rotation angle, wherein the reverse rotation angle of the lens assembly 100 is equal to the rotation angle. However, generally speaking, the size of the above-mentioned device capable of detecting the angle of rotation of the lens assembly 100 relative to its initial position is relatively large, and the cost is relatively high, such as a gyroscope, a gravity sensor, and the like. Based on this, in another embodiment of the present application, the camera module may optionally include an angle detecting member capable of detecting the rotation angle of the lens assembly 100 relative to the device body, and there are various devices for detecting the magnitude and direction of the relative rotation angle between the two components, and among them, there are many devices having features of small size and low cost, such as a micro slide rheostat, a distance sensor, and an sar (Specific Absorption Rate) sensor.

In the case where the above-described angle sensor is provided in the camera module, the lens assembly 100 may be driven to rotate by the driving assembly 320 according to the rotation angle detected by the angle sensor. Of course, during the operation of the driving assembly 320, besides the rotation angle detected by the angle detecting member, the rotation angle of the device body relative to its initial position needs to be obtained, so as to obtain the rotation angle of the lens assembly 100 relative to its initial state, i.e. the absolute rotation angle of the lens assembly 100. Because the camera module can be generally applied to electronic equipment, devices such as a gyroscope and a gravity sensor are standard configurations of the electronic equipment, and then, the angle rotated by the equipment body relative to the initial state of the equipment body can be obtained by means of the devices such as the gyroscope and the gravity sensor in the electronic equipment, the angle rotated by the lens assembly 100 relative to the initial state of the equipment body can be obtained by combining the relative rotation angle of the lens assembly 100 and the equipment body detected by the angle detection piece, and therefore, the lens assembly 100 can be restored to the initial state by controlling the movement of the mecanum wheel 301, so that the relative angle between the lens assembly 100 and a view finding area is always kept unchanged, and the anti-shaking purpose is realized.

When adopting above-mentioned technical scheme, the measurement work of the absolute turned angle (the angle that lens subassembly 100 rotated for the initial condition of self) of lens subassembly 100 can be assisted the completion with the help of the device of standard in the electronic equipment, can reduce the cost of camera module on the one hand, and on the other hand can also reduce the overall size of camera module, can also make the utilization ratio of devices such as gyroscope and gravity sensor in the electronic equipment obtain promoting, reduces overall cost in a certain sense.

In the above embodiment, by cooperating with the fitting assembly 310, the mecanum wheel 301 in the driving assembly 320 can be in rolling fit with the lens assembly 100, so as to drive the lens assembly 100 to rotate around the optical axis of the lens assembly 100 relative to the device body. Alternatively, the mating portion and the surface of the device body facing the mating portion may be flat, in which case, the mating component 310 and the driving component 320 are in rolling engagement with the flat, and in the case of the driving component 320 acting, the lens component 100 can be ensured to be able to rotate relative to the lens component 100.

In another embodiment of the present application, optionally, as shown in fig. 2 and 4, the matching portion is provided with a first spherical surface 122 and a second spherical surface 123, the first spherical surface 122 and the second spherical surface 123 both protrude toward a direction close to the second mounting bracket 220, the first mounting bracket 210 is disposed on a side of the first spherical surface 122 facing away from the second spherical surface 123, and the second mounting bracket 220 is disposed on a side of the second spherical surface 123 facing away from the first spherical surface 122. That is to say, the fitting portion is a spherical shell structure, and the fitting portion protrudes outward, the first spherical surface 122 is an inner wall surface of the fitting portion, the second spherical surface 123 is an outer wall surface of the fitting portion, the first mounting frame 210 is located inside the lens assembly 100 and is fitted with the first spherical surface 122, and the second mounting frame 220 is disposed outside the lens assembly 100 and is fitted with the second spherical surface 123.

With the above technical solution, one of the matching component 310 and the driving component 320 may be connected to the first spherical surface 122, and the other may be connected to the second spherical surface 123, and under the driving action of the driving component 320, the lens component 100 can also be ensured to rotate relative to the device body.

Based on the above embodiment, in order to make the fitting effect between the first and

second mounts

210 and 220 and the fitting portion better, optionally, both the first and

second mounts

210 and 220 may be spherical structures, which may make the fitting effect between the first and

second mounts

210 and 220 and the fitting portion better, so as to further improve the fitting effect between the driving assembly 320 and the fitting assembly 310 and the fitting portion.

Optionally, the first and

second mounts

210 and 220 are similar in structure, and in particular, the first and

second mounts

210 and 220 each include a connecting rod, each connecting rod is an arc-shaped structural member, in this case, the overall structure of the first and

second mounts

210 and 220 is relatively simple, and by connecting one end of each connecting rod with the connecting portion 230, the first and

second mounts

210 and 220 can be in fixed connection with the connecting portion 230, and the other end of each connecting rod can be provided with the driving component 320 or the matching component 310. And, the shaping degree of difficulty of the connecting rod of arc structure is less relatively, and this can reduce the processing degree of difficulty of first mounting bracket 210 and second mounting bracket 220. In addition, the bending precision of the connecting rod is easy to control, so that the matching precision of the first mounting frame 210 and the second mounting frame 220 with the matching parts of the spherical structures can be improved, and the precision is higher when the lens assembly 100 and the equipment body rotate relatively.

Correspondingly, in the case that the number of the driving components 320 and the number of the fitting components 310 are both multiple, each of the first and second mounting

frames

210 and 220 may include multiple connecting rods, taking the fitting component 310 mounted on the second mounting frame 220 as an example, the multiple fitting components 310 may be mounted on the multiple connecting rods in a one-to-one correspondence, and the multiple connecting rods may be distributed uniformly and at intervals around the optical axis of the lens assembly 100, so that the fitting stability between the lens assembly 100 and the device body is higher.

As described above, in the case where the fitting portion has the first spherical surface 122 and the second spherical surface 123, the lens assembly 100 can not only rotate about the optical axis of the lens assembly 100 with respect to the apparatus body, but also provide a base on which the optical axis of the lens assembly 100 rotates with respect to the apparatus body, so that the orientation of the lens assembly 100 can be changed while the position of the apparatus body remains unchanged.

Further, in order to ensure that the driving assemblies 320 can drive the optical axis of the lens assembly 100 to rotate relative to the apparatus body, optionally, as shown in fig. 5, the number of the driving assemblies 320 is at least three, at least three driving assemblies 320 are all mounted on the first mounting frame 210, or at least three driving assemblies 320 are all mounted on the second mounting frame 220, in which case, the optical axis of the lens assembly 100 can rotate relative to the apparatus body along with the movement of each driving assembly 320. In the case where the number of the driving assemblies 320 is at least three, the extending direction of the wheel axle of each driving assembly 320 may be determined according to the relative positional relationship between each driving assembly 320, thereby ensuring that the lens assembly 100 can change its orientation with respect to the device body by controlling the movement of each driving assembly 320.

In the case of the above-described solution, each of the driving units 320 includes a mecanum wheel 301, and the components connected to the mecanum wheels 301 can be freely moved in different directions on the supporting surface by combining at least three mecanum wheels 301 based on the operating principle of the mecanum wheels 301. The driving components 320 may be installed inside the lens assembly 100 or outside the lens assembly 100, and by cooperating with the matching component 310, the lens assembly 100 can be rotated in different directions relative to the device body under the condition that the driving components 320 generate corresponding driving actions.

As described above, in order to ensure high rotational reliability between the lens assembly 100 and the apparatus body, the lens assembly 100 and the apparatus body may be connected by the connection part 230 such that the connection part 230 provides a function similar to a rotation shaft. In the case where the number of the driving assemblies 320 is at least three, it is necessary to space the connection part 230 and the lens assembly 100 from each other so as to prevent the connection part 230 from obstructing the lens assembly 100 from rotating relative to the apparatus body to change the orientation of the lens assembly 100.

The at least three driving assemblies 320 may ensure that the lens assembly 100 and the device body can form a stable connection relationship, and prevent the lens assembly 100 from being separated from the device body. Of course, in the process of arranging at least three driving assemblies 320, it is necessary to ensure that a certain positional relationship is satisfied between the driving assemblies 320. For example, the driving assembly 320 may be arranged in a non-straight line, so as to prevent the unstable connection between the lens assembly 100 and the apparatus body, and prevent the lens assembly 100 from rotating relative to the apparatus body only in a fixed direction. For another example, when there are three driving assemblies 320, the three driving assemblies 320 need to be disposed around the optical axis of the lens assembly 100 to ensure that the connection stability between the lens assembly 100 and the device body is high and the rotation range between the lens assembly 100 and the device body is wide.

Alternatively, the camera module is provided with a controller to control the at least three driving assemblies 320 through the controller, or the camera module may be connected with a controller of the electronic device to control the working conditions of the at least three driving assemblies 320 through the controller of the electronic device.

With the above technical solution, the lens assembly 100 can not only rotate around its optical axis, but also the optical axis of the lens assembly 100 can rotate relative to the apparatus body, taking the case that the lens assembly 100 rotates around its optical axis as the (middle plane of) the lens assembly 100 rotates in the XY plane as an example, by adopting the above solution, the (middle plane of) the lens assembly 100 can also rotate in the XZ and YZ planes, so that the orientation of the lens assembly 100 is changed. In the process of shooting by adopting the camera module, the motion conditions of the at least three driving components 320 can be correspondingly controlled according to the shaking conditions of the user, so that the lens assembly 100 generates opposite shaking conditions, the condition that the viewing range changes due to the shaking of the user is compensated, the viewing range of the lens assembly 100 is basically kept unchanged, the anti-shaking purpose is realized, and the definition of an image shot by the camera module is improved.

Optionally, the driving assembly 320 is mounted on the second mounting bracket 220, in which case the driving assembly 320 is connected with both the lens assembly 100 and the device body, and the driving assembly 320 is mounted outside the lens assembly 100. Compared with the space inside the lens assembly 100, the space outside the lens assembly 100 is relatively larger, so that the movable range of the driving assembly 320 is larger, the adjustment range of the driving assembly 320 is widened, the rotation range of the lens assembly 100 is enlarged, the anti-shake performance of the camera module is improved, and the user experience is improved.
