Description

Shooting module and electronic equipment

Technical Field

The application relates to the technical field of shooting, and more particularly relates to a shooting module and an electronic device.

Background

When shooting, light enters the image sensor through the lens, and the slight shake in the light sensing process causes the change of an imaging point of the light on the sensor, thereby causing image blurring. The shake may be from the photographer or may be external disturbance, and shortening the shutter time may reduce the shake blur to some extent but cannot be completely eliminated. Compensation is currently usually achieved by mechanical stabilization, for example, by moving the lens or module to compensate for the jitter. However, the mechanical transmission mechanism often has a backlash in the transmission process, which affects the anti-shake effect.

Referring to fig. 1 to 3, a camera module 100 is provided in an embodiment of the present disclosure. The photographing module 100 includes a housing 10, a lens assembly 20, and an elastic member 30. The lens assembly 20 is partially housed in the housing 10, and the lens assembly 20 can rotate and swing relative to the housing 10. The elastic member 30 elastically connects the housing 10 and the lens assembly 20, and the elastic member 30 is used to apply an elastic force to the lens assembly 20 so that the backlash of the lens assembly 20 is within a preset range.

The camera module 100 in the present application elastically connects the housing 10 and the lens assembly 20 by providing the elastic member 30, and applies an elastic force to the lens assembly 20 so that the backlash of the lens assembly 20 is within a preset range. This is advantageous to keep the lens assembly 20 rotating normally, thereby increasing the anti-shake performance of the photographing module 100.

The following is further described with reference to the accompanying drawings.

Referring to fig. 1 to 3, the camera module 100 includes a housing 10, a lens assembly 20, an elastic member 30, a bearing assembly 40 and a driving assembly 50. The lens assembly 20 is partially received in the housing 10, the bearing assembly 40 is received in the housing 10, and the lens assembly 20 is inserted through the bearing assembly 40. The driving assembly 50 is connected to the lens assembly 20 and is used for driving the lens assembly 20 to rotate and swing in the housing 10.

Specifically, referring to fig. 3, the bearing assembly 40 includes a first bearing 41 and a second bearing 42. The first bearing 41 is accommodated in the housing 10 and fixedly connected with the housing 10; the second bearing 42 is accommodated in the first bearing 41, the second bearing 42 is rotatable and swingable relative to the first bearing 41, and the lens unit 20 is partially inserted into the second bearing 42 and is fixedly connected to the second bearing 42.

Since the second bearing 42 can rotate and swing relative to the first bearing 41, the first bearing 41 is fixedly connected with the housing 10, and the lens assembly 20 is fixedly connected with the second bearing 42, so that the lens assembly 20 can rotate and swing relative to the housing 10 under the driving of the driving assembly 50. In this way, when the camera module 100 shoots, if the camera module 100 shakes, the lens assembly 20 can be driven by the driving assembly 50 to rotate and swing to compensate and correct the shake, so that the anti-shake function is realized, and the imaging quality is improved. Small-angle (for example, ± 10 ° or less) movement of the camera module 100 in the Pitch, Yaw and Roll directions is realized, so that five-axis anti-shake of the camera module 100 is realized. And, do not need to be the same with cloud platform anti-shake (GS) scheme, occupy great stabilizer volume, and the consumption is great, is favorable to realizing the anti-shake function of less equipment.

Referring to fig. 3 and 4, in some embodiments, a side of the first bearing 41 close to the second bearing 42 is a spherical surface, and a side of the second bearing 42 close to the first bearing 41 is also a spherical surface. In this way, on the one hand, the second bearing 42 can stably swing rotationally with respect to the first bearing 41; on the other hand, the sliding friction between the first bearing 41 and the second bearing 42 can be reduced, and the resistance can be reduced. It will be appreciated that in order to further reduce friction, in some embodiments, lubricating oil may be injected between the first bearing 41 and the second bearing 42; alternatively, in some embodiments, a rolling member, such as a ball, may be disposed between the first bearing 41 and the second bearing 42, and the rolling member may roll with respect to the first bearing 41 and the second bearing 42 to reduce friction, so that the movement of the second bearing 42 is smoother.

Referring to fig. 3, the elastic member 30 is accommodated in the housing 10, and the elastic member 30 elastically connects the housing 10 and the lens assembly 20 and is used for applying an elastic force to the lens assembly 20 so that the backlash of the lens assembly 20 is within a predetermined range. Since the lens assembly 20 can rotate and swing relative to the housing 10 under the driving of the driving assembly 50, when the driving assembly 50 drives the lens assembly 20 to rotate in one direction, a backlash occurs on the side opposite to the moving direction, so that when the driving assembly 50 drives the lens assembly 20 to rotate in the opposite direction, the driving assembly 50 needs to pass through the backlash before the driving assembly 50 can drive the lens assembly 20 to normally rotate. In the embodiment of the present application, the elastic component 30 applies an elastic force to the lens assembly 20 to make the back clearance of the lens assembly 20 within a preset range, which is beneficial for the lens assembly 20 to keep rotating normally, so as to increase the anti-shake performance of the shooting module 100.

It should be noted that, in some embodiments, the back clearance is a distance between a projection center of the lens assembly 20 on the vertical optical axis plane and a preset position. When the lens assembly 20 is in the initial state, the projection center and the preset position of the lens assembly 20 on the vertical optical axis plane are within the preset range, and when the driving assembly 50 drives the lens assembly 20 to rotate in one direction, the distance between the projection center and the preset position of the lens assembly 20 on the vertical optical axis plane on the opposite side of the movement direction is increased, so that when the driving assembly 50 drives the lens assembly 20 to rotate in the opposite direction, the driving assembly 50 can drive the lens assembly 20 to normally rotate only after the projection center and the preset position of the lens assembly 20 on the vertical optical axis plane are within the preset range. Wherein the preset position may include a center of projection of the first bearing 41 on the vertical optical axis plane. The elastic member 30 applies an elastic force to the lens assembly 20 so that the backlash of the lens assembly 20 is within a predetermined range, that is, the distance between the projection center of the lens assembly 20 on the vertical optical axis plane and the projection center of the first bearing 41 on the vertical optical axis plane is within a predetermined range, which is beneficial to the lens assembly 20 to keep rotating normally, thereby increasing the anti-shake performance of the photographing module 100.

Referring to fig. 3 and 4, in some embodiments, the bearing assembly 40 includes a first side 401 and a second side 402 opposite to each other, the first side 401 of the bearing assembly 40 is closer to the image side of the photographing module 100 than the second side 402, and the elastic member 30 is disposed on the first side 401 of the bearing assembly 40. Since the elastic member 30 is disposed on the side of the bearing assembly 40 close to the image side of the camera module 100, the elastic member 30 can be prevented from being exposed outside the camera module 100, and the elastic member 30 can be prevented from being damaged. Of course, in some embodiments, the resilient member 30 may also be disposed on the second side 402 of the bearing assembly 40, without limitation. It should be noted that, the elastic member 30 is disposed on the first side 401 of the bearing assembly 40, and the elastic member 30 is not limited to be disposed on the bearing assembly 40, and the elastic member 30 may also be disposed on other devices but on the first side 401 of the bearing assembly 40; similarly, the resilient member 30 is disposed on the second side 402 of the bearing assembly 40, and the resilient member 30 is not limited to being disposed on the bearing assembly 40, and the resilient member 30 may be disposed on other devices but on the second side 402 of the bearing assembly 40.

In some embodiments, the number of the elastic members 30 may be multiple, that is, the camera module 100 includes multiple elastic members 30. Therefore, the elastic force applied to the lens module 20 can be improved, and the back clearance of the lens module 20 can be kept within a preset range all the time. It should be noted that, when the camera module 100 includes a plurality of elastic members 30, in some embodiments, all of the elastic members 30 are disposed on the first side 401 of the bearing assembly 40; alternatively, in some embodiments, all of the resilient members 30 are disposed on the second side 402 of the bearing assembly 40; alternatively, in some embodiments, a portion of resilient member 30 is disposed on first side 401 of bearing assembly 40 and a portion of resilient member 30 is disposed on second side 402 of bearing assembly 40, without limitation.

Referring to fig. 5, the elastic member 30 includes a first mounting member 31, a second mounting member 32 and at least one elastic connecting member 33. The second mounting element 32 is located within the first mounting element 31 and spaced from the first mounting element 31; the connecting member 33 is used to elastically connect the first mounting member 31 and the second mounting member 32. It is noted that in some embodiments, the resilient member 30 may be a stainless steel resilient member; alternatively, in some embodiments, the elastic member 30 may also be a magnesium aluminum alloy elastic member, which is not limited herein.

Specifically, referring to fig. 3 and 5, the first mounting member 31 is disposed on the housing 10 or the first bearing 41, and the second mounting member 32 is disposed on the lens assembly 20 or the second bearing 42. Since the first mounting unit 31 is disposed on a relatively fixed device (the housing 10 or the first bearing 41) of the photographing device 100, the second mounting unit 32 is disposed on a relatively movable device (the lens assembly 20 or the second bearing 42) of the photographing device 100, and the first mounting unit 31 and the second mounting unit 32 are elastically connected by the connection member 33. This enables to apply an elastic force to the lens assembly 20 so that the backlash of the lens assembly 20 is within a preset range. For example, as shown in fig. 3, in some embodiments, the first mounting member 31 is mounted on an inner sidewall of the housing 10, and the second mounting member 32 is mounted on an outer sidewall of the lens assembly 20. In this way, the connecting member 33 elastically connects the first mounting member 31 and the second mounting member 32 to elastically connect the lens assembly 20 and the housing 10, and applies an elastic force to the lens assembly 20 to keep the backlash of the lens assembly 20 within a predetermined range. Of course, in some embodiments, the first mount 31 is mounted on a first bearing 41 fixedly connected to the housing 10, and the second mount 32 is mounted on a second bearing 42 fixedly connected to the lens assembly 20; alternatively, in some embodiments, the first mount 31 is mounted on an inner sidewall of the housing 10, and the second mount 32 is on the second bearing 42 fixedly connected to the lens assembly 20; alternatively, in some embodiments, the first mounting part 31 is mounted on the first bearing 41 fixedly connected with the housing 10, and the second mounting part 32 is mounted on the outer sidewall of the lens assembly 20, which is not limited herein.

It should be noted that in some embodiments, the first mounting part 31 and the second mounting part 32 of the elastic component 30 may be both installed on the same side of the bearing assembly 40, for example, as shown in fig. 3, the first mounting part 31 is installed on the inner side wall of the housing 10 and is located on the first side 401 of the bearing assembly 40; the second mount 32 is mounted to an outer sidewall of the lens assembly 20 and is located on the first side 401 of the bearing assembly 40. Since the first mounting member 31 and the second mounting member 32 are both mounted on the same side of the bearing assembly 40, the elastic member 30 can be mounted conveniently, and the assembly difficulty of the camera module 100 can be reduced. Of course, in some embodiments, the first mounting part 31 and the second mounting part 32 of the elastic member 30 may be mounted on both sides of the bearing assembly 40. For example, the first mounting member 31 is mounted on the inner sidewall of the housing 10 and is located on the first side 401 of the bearing assembly 40; the second mount 32 is mounted to an outer sidewall of the lens assembly 20 and is positioned on the second side 402 of the bearing assembly 40. The connecting member 33 connecting the first mounting member 31 and the second mounting member 32 has a larger deformation space.

Referring to fig. 6, in some embodiments, when the connecting member 33 is elastically deformed, that is, when the elastic member 30 is in the working state, a distance between the first mounting part 31 and the second mounting part 32 in the direction along the optical axis X of the lens assembly 20 is greater than a preset distance. For example, fig. 6 shows a schematic structural diagram of the elastic member 30 when the elastic member 30 is in an operating state, that is, the connection portion 33 is elastically deformed. In the figure, the dotted line indicates the direction of the optical axis X of the lens assembly 20, and a side away from the arrow is a light incident side (i.e., an object side) of the lens assembly 20. As shown in fig. 6, when the connecting portion 33 is elastically deformed, the distance between the first mounting member 31 and the second mounting member 32 along the direction of the optical axis X is greater than the predetermined distance, and the second mounting member 32 is closer to the light incident side of the lens assembly 20 than the first mounting member 31. This enables the direction of the elastic force applied to the lens module 20 to be uniform over the stroke range of the link 33. Of course, in some embodiments, when the connecting portion 33 is elastically deformed, the distance between the first mounting part 31 and the second mounting part 32 along the optical axis X direction is greater than the preset distance, and the first mounting part 31 may be closer to the light incident side of the lens assembly 20 than the second mounting part 32, which is not limited herein.

Referring to fig. 5 and 7, in some embodiments, the elastic member 30 includes a plurality of connecting members 33, so that the elastic connecting force of the elastic member 30 can be increased to facilitate the backlash of the lens assembly 20 within a predetermined range. Specifically, in one example, as shown in fig. 5, the plurality of connecting members 33 are evenly distributed between the first mounting member 31 and the second mounting member 32. Wherein the number of connecting pieces 33 may be 2, 3, 4 or even more. Since the plurality of connecting members 33 are uniformly distributed between the first mounting member 31 and the second mounting member 32, the elastic force applied by the elastic member 30 to the lens module 20 can be more uniform. In another example, the elastic member 30 has a symmetry axis L perpendicular to the optical axis X, and the plurality of coupling members 33 are symmetrical about the symmetry axis when the coupling members 33 are not elastically deformed. Illustratively, as shown in fig. 7, the elastic member 30 includes a connecting member 3301, a connecting member 3302, a connecting member 3303, and a connecting member 3304. Wherein the connecting member 3301 and the connecting member 3302 are symmetrical about the symmetry axis L1; the connecting members 3303 and 3304 are symmetrical about the symmetry axis L2, and the symmetry axis L1 and the symmetry axis L2 are perpendicular to the optical axis X. The number of the connecting pieces 33 may be 2, 4 or more, and the number of the corresponding symmetry axes may also be 1, 2 or more. This makes it possible to make the elastic force applied to the lens assembly 20 by the elastic member 30 more uniform.

Referring to fig. 5, one side of the connecting member 33 is connected to the first mounting member 31 to form a first connecting point 34, and the other side of the connecting member 33 is connected to the second mounting member 32 to form a second connecting point 35. In some embodiments, the connecting member 33 has at least one bending portion 331 between the first mounting member 31 and the second mounting member 32. Since the connecting member 33 has at least one bent portion 331 between the first mounting member 31 and the second mounting member 32, the elastic deformation stroke of the connecting member 33 can be increased, which is beneficial to keep the lens assembly 20 rotating normally.

For example, in some embodiments, the number of the bent portions 331 of the same connecting member 33 is multiple, and each of the bent portions 331 is symmetric with respect to the center point 36 of the connecting member, which is beneficial to ensure the force consistency of the connecting member 33 in the direction of the pitch axis and the yaw axis of the camera module 100, and to keep the lens assembly 20 normally rotating. In particular, in some embodiments, the first connection point 34, the second connection point 35 and the middle point 36 of the connection member are located on the same straight line, which is more beneficial to ensure the force consistency of the connection portion 33 in the direction of the pitch axis and the yaw axis of the camera module 100, and to keep the lens assembly 20 rotating normally.

Referring to fig. 3 and 4, the driving assembly 50 is connected to the lens assembly 20, and the driving assembly 50 is used for driving the lens assembly 20 to rotate and swing relative to the housing 10. In this way, when the camera module 100 shoots, if the camera module 100 shakes, the lens assembly 20 can be driven by the driving assembly 50 to rotate and swing to compensate and correct the shake, so that the anti-shake function is realized, and the imaging quality is improved. Small-angle (for example, ± 10 ° or less) movement of the camera module 100 in the Pitch, Yaw and Roll directions is realized, so that five-axis anti-shake of the camera module 100 is realized. And, do not need to be the same with cloud platform anti-shake (GS) scheme, occupy great stabilizer volume, and the consumption is great, is favorable to realizing the anti-shake function of less equipment.

Specifically, the driving assembly 50 includes a coil 51 and a magnetic member 52, the coil 51 and the magnetic member 52 are disposed in spaced opposition, one of the coil 51 and the magnetic member 52 is fixed to the lens assembly 20, and the other is fixed to the housing 10. The coil 51 is used for generating a force interacting with the magnetic member 52 when the power is turned on to drive the lens assembly 20 to swing and rotate relative to the housing 10. In this way, when the lens assembly 20 needs to be driven to rotate and swing, the coil 51 can be energized, and the coil 51 generates a magnetic field, so as to generate an interaction force with the magnetic member 52 to drive the lens assembly 20 to rotate and swing relative to the housing 10, so as to compensate for the shake.

Illustratively, in some embodiments, as shown in fig. 3, the coil 51 is fixedly disposed on the housing 10, and the magnetic member 52 is fixedly disposed on the lens assembly 20. In this manner, the arrangement of the coil 51 having a lighter weight on the lens assembly 20 may reduce resistance to movement of the lens assembly 20, which may in turn allow the coil 51 to be made smaller. Of course, in some embodiments, the coil 51 may also be fixedly disposed on the lens assembly 20, and the magnetic body 52 is fixedly disposed on the housing 10, which is not limited herein.

As shown in fig. 3 and 4, in some embodiments, the driving assembly 50 further includes a mounting base 53, the mounting base 53 is fixedly connected to the lens assembly 20, and the mounting base 53 is used for fixedly mounting the coil 51.

So, can install coil 51 on mounting base 53 earlier, then with mounting base 53 fixed mounting on lens subassembly 20 to realize the fixed connection of coil 51 and lens subassembly 20, like this, when needing to change or maintain coil 51, only need with mounting base 53 take off from lens subassembly 20 can, and need not to pull down whole lens subassembly 20 or directly change and maintain on such a bulky component of lens subassembly 20, and is simple and convenient.

Referring to fig. 3 and 4, in some embodiments, the camera module 100 further includes a yoke 54, the magnetic element 52 is mounted on the yoke 54, and the yoke 54 is fixedly connected to the housing 10. In this way, the presence of the yoke 54 can enhance the attraction force of the coil 51, thereby improving the driving efficiency of the coil 51. Specifically, in such embodiments, the yoke 54 may be a single-sided yoke or a double-sided yoke, preferably a double-sided yoke.

Referring to fig. 8, in some embodiments, the geometric center N of the coil 51 is substantially perpendicular to the plane 511 in which the coil 51 is mounted, and the center M of the bearing assembly 40.

In this way, when the lens assembly 20 swings the coil 51 or the magnetic member 52 around the centerline of the bearing assembly 40, the swing radius thereof is small, so that the driving force can be satisfied as much as possible without interfering the movement of the coil 51 or the magnetic member 52, and at the same time, the gap h between the coil 51 and the magnetic member 52 is reduced, so as to improve the driving efficiency of the driving assembly 40, and at the same time, the overall size of the camera module 1000 is greatly reduced.

Specifically, referring to fig. 8, in the embodiment, the lens assembly 20 swings around the center M of the bearing assembly 40, that is, the coil 51 on the lens assembly 20 also swings around the center M of the bearing assembly 40, the movement locus L of the coil 51 is a circular arc, and the radius of the movement locus of the center N of the coil 51 is the length of the connection between the center M of the bearing assembly 40 and the geometric center N of the coil 51.

It can be understood that, referring to fig. 9, if the connecting line between the center M of the bearing assembly 40 and the geometric center N of the coil 51 is not substantially perpendicular to the plane 511 for mounting the coil 51, the radius of the movement locus L1 of the coil 51 is obviously larger than the radius L in fig. 8, so that the gap h between the coil 51 and the magnetic member 52 needs to be sufficiently large, and if the gap h between the magnetic member 52 and the coil 51 is too small, the coil 51 is caused to interfere with the magnetic member 52 during movement, thereby affecting the movement of the lens assembly 20, however, if the gap h between the magnetic member 52 and the coil 51 is too large, the driving efficiency is too low, so that designing the connecting line between the geometric center N of the coil 51 and the center M of the bearing assembly 40 to be substantially perpendicular to the plane 511 for mounting the coil 51 can reduce the radius of the movement locus of the coil 51 as much as possible, thereby minimizing the gap h between the coil 51 and the magnetic member 52, thereby improving the driving efficiency.

Referring to fig. 10, the present application further provides an electronic device 1000. The electronic device 1000 includes a housing 200 and the camera module 100 according to any of the above embodiments, and the camera module 100 is disposed in the housing 200. It should be noted that the electronic device 1000 may be a mobile phone, a camera, a tablet computer, a smart watch, a smart wearable device, and the like, which is not limited herein.

The shooting module 100 in the electronic device 1000 in the present application elastically connects the housing 10 and the lens assembly 20 by providing the elastic member 30, and applies an elastic force to the lens assembly 20 so that the backlash of the lens assembly 20 is within a preset range. This is beneficial to the lens assembly 20 to keep rotating normally, and can increase the anti-shake performance of the shooting module 100, thereby increasing the anti-shake performance of the electronic device 1000.
