Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

Technical solutions disclosed in the embodiments of the present application are described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 9, the present application discloses a camera module including a lens assembly 110, a module holder 400, and a driving assembly. Certainly, other devices such as the photosensitive chip 130 may also be disposed in the camera module, and the photosensitive chip 130 may be mounted on a side of the lens assembly 110 away from the light incident side.

The lens assembly 110 includes at least one lens, light rays outside the camera module can be incident into the camera module through the lens assembly 110, and the lens assembly 110 can provide a light distribution effect for the light rays. The module holder 400 is a mounting base for the lens assembly 110, and the module holder 400 can provide a certain protection for the lens assembly 110. The module holder 400 can be made of metal or plastic, and the shape and specific structure thereof can be various, for example, the module holder 400 can be disposed on one side of the lens assembly 110 and on the side of the lens assembly 110 away from the light incident side, so that the lens assembly 110 can be mounted on the module holder 400 through the bottom thereof. In order to improve the protection effect of the lens assembly 110, as shown in fig. 6 and 7, the module holder 400 may be disposed outside the lens assembly 110, so that at least a portion of the bottom and the side of the lens assembly 110 may be surrounded by the module holder 400, thereby improving the service life of the camera module.

The lens assembly 110 is rotatably coupled to the module holder 400 such that the lens assembly 110 is capable of rotating relative to the module holder 400 upon actuation of the actuation assembly. Specifically, the lens assembly 110 and the module holder 400 may be connected to each other only by the driving assembly; alternatively, the two can be connected in a rotating manner through other components. For example, a pivot may be disposed between the lens assembly 110 and the module mount 400, the pivot extending along the optical axis of the lens assembly 110 to ensure that the lens assembly 110 can pivot relative to the module mount 400 about the optical axis of the lens assembly 110. Of course, the lens assembly 110 and the module holder 400 can be connected by other connecting members, so that the lens assembly 110 and the module holder 400 can be rotatably connected, and for the sake of brevity, the examples are not repeated here.

The driving assembly includes a conductive member 210 and a magnetic member 220, one of the conductive member 210 and the magnetic member 220 is fixed on the lens assembly 110, the other one is fixed on the module holder 400, the magnetic member 220 includes a first magnetic pole 221 and a second magnetic pole 222 which are oppositely and alternately arranged, and the conductive member 210 is arranged between the first magnetic pole 221 and the second magnetic pole 222. The conductive member 210 may be a conductive wire, and when the conductive member 210 is powered on, that is, the conductive wire is powered on, the conductive wire may be acted by an ampere force in the magnetic field, so that the conductive wire and the magnetic member 220 can move relatively. By designing the assembly manner of the conductive member 210 and the magnetic member 220, for example, the force direction of the conductive member 210 is perpendicular to the optical axis of the lens assembly 110, the conductive member 210 can drive the lens assembly 110 to rotate around the optical axis of the lens assembly 110 relative to the module holder 400; the conductive member 210 in the power-on state is ensured to drive the lens assembly 110 to rotate around the optical axis of the lens assembly 110 relative to the module bracket 400.

Specifically, the conductive member 210 and the magnetic member 220 can be disposed on a side of the lens assembly 110 facing away from the light incident side, and there are various connection manners between the lens assembly 110 and the module holder 400 and the driving assembly. For example, one of the conductive member 210 and the magnetic member 220 may be fixed to the lens assembly 110 and the other may be fixed to the module holder 400 by means of adhesion. Alternatively, the lens assembly 110 and the module holder 400 can be fixedly connected to the driving assembly by screws or other connecting members. Alternatively, the magnetic member 220 is a single magnet, or the magnetic member 220 may be a combination structure of two magnets, and in the case that the magnetic member 220 includes two magnets, the magnetic poles of the first magnetic pole 221 and the second magnetic pole 222 respectively disposed on two opposite sides of the conductive member 210 need to be different, so as to ensure that the conductive member 210 can be in the magnetic field. In addition, the magnetic member 220 may be a permanent magnet or an electromagnet.

As mentioned above, the conductive member 210 may be a wire, and in another embodiment of the present application, the conductive member 210 may be a coil, and the coil is connected to the lens assembly 110 or the module holder 400. In this case, the coil is only directly connected to the power source, and there is no need to add an interconnection wire or the like to the conductive member 210, so that the coil can be powered by the power source when the lens assembly 110 and the module holder 400 need to be driven to move relative to each other.

It should be noted that the magnetic member 220 generally has a certain structural strength, and is not separately explained here. In the camera module provided by the present application, the conductive member 210 needs to have a structural strength meeting the requirement, so as to ensure that the conductive member 210 can drive the lens assembly 110 and the module bracket 400 to move relatively and hardly deform when interacting with the magnetic member 220. In order to ensure that the driving difficulty of the driving assembly is smaller, as described above, a rotating shaft may be disposed between the lens assembly 110 and the module holder 400, so as to reduce the rotation difficulty between the lens assembly 110 and the module holder 400, and prevent the conductive member 210 and the magnetic member 220 from being affected by the acting force along the optical axis direction of the lens assembly 110, which may adversely affect the normal driving operation of the driving assembly.

The application discloses a camera module, it includes lens subassembly 110, module support 400 and drive assembly, lens subassembly 110 and module support 400 rotatable coupling, drive assembly includes electrically conductive piece 210 and magnetic part 220, one in electrically conductive piece 210 and magnetic part 220 is fixed with lens subassembly 110, the other is fixed with module support 400, magnetic part 220 includes first magnetic pole 221 and second magnetic pole 222, electrically conductive piece 210 sets up between first magnetic pole 221 and second magnetic pole 222. Under the condition that the conductive element 210 is electrified, the driving element can drive the lens assembly 110 to rotate around the optical axis of the lens assembly 110 relative to the module bracket 400, so that in the working process of the camera module, even if the camera module rotates around the optical axis of the camera module due to shaking, the conductive element 210 can be electrified to enable the conductive element 210 and the magnetic element 220 to move relatively, so that the lens assembly 110 is driven to rotate around the optical axis of the lens assembly 110, the phenomenon of smear generated due to the rotation of the camera module is compensated, the relative position (or relative angle) between the lens assembly 110 and a viewing area is kept unchanged, the phenomenon of image smear caused by the rotation of the camera module is prevented, and the imaging quality of the camera is high.

In detail, in the camera module disclosed in the above embodiment, under the condition that the structure of the conductive element 210 and the magnetic field of the magnetic element 220 are not changed, the magnitude of the ampere force applied to the conductive element 210 in the magnetic field can be changed by changing the magnitude of the current applied to the conductive element 210, so that the relative displacement between the conductive element 210 and the magnetic element 220 is different. Furthermore, when the camera module rotates at different angles due to shaking, the current applied to the conductive member 210 can be controlled to generate a predetermined displacement in the opposite direction between the lens assembly 110 and the module holder 400, so that the relative position or the relative angle between the lens assembly 110 and the viewing area is always kept constant. Correspondingly, when the directions of rotation of the camera module caused by shaking are different, as shown in fig. 1, the direction of the current I flowing into the conductive member 210 can be changed to change the direction of the relative rotation between the lens assembly 110 and the module holder 400. Moreover, in the case that the magnetic element 220 is an electromagnet, the purpose of changing the magnitude of the ampere force applied to the conductive element 210 can be achieved by changing the magnetic field strength of the magnetic element 220.

In addition, in the camera module disclosed in the above embodiment, an angle detection device such as a gyroscope capable of detecting the rotation of the lens assembly 110 may be provided, so that during shooting, the rotation of the lens assembly 110 around its own optical axis direction with respect 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, the driving assembly may be correspondingly controlled, and the driving assembly may be driven to rotate the lens assembly 110 by a preset angle in a preset direction by supplying a current with a preset direction and a preset magnitude to the conductive member 210, so as to compensate for the unexpected rotation of the lens assembly 110 due to shaking, and ensure that the relative angle between the lens assembly 110 and the viewing area is substantially kept unchanged.

As described above, the anti-shake effect can be achieved by detecting the rotation angle of the lens assembly 110 relative to its initial position, and controlling the driving assembly to drive the lens assembly 110 to rotate in the reverse direction according to the rotation angle, wherein the reverse rotation angle of the lens assembly 110 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 110 with respect 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 optionally includes an angle detector capable of detecting the rotation angle of the lens assembly 110 relative to the module bracket 400, and there are many kinds of devices capable of detecting the magnitude and direction of the relative rotation angle between the two devices, and 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 110 may be driven to rotate by the driving assembly according to the rotation angle detected by the angle sensor. Of course, in the process of the lens assembly 110 being driven by the driving assembly to rotate relative to the module holder 400, in addition to the rotation angle detected by the angle detector, the rotation angle of the module holder 400 relative to its initial position needs to be obtained, so as to obtain the rotation angle of the lens assembly 110 relative to its initial state, that is, the absolute rotation angle of the lens assembly 110. Because the camera module can be generally applied to electronic equipment, and devices such as a gyroscope and a gravity sensor are standard configurations of the electronic equipment, further, the angle that the module bracket 400 rotates relative to the initial state of the camera module can be obtained by means of the devices such as the gyroscope and the gravity sensor in the electronic equipment, the angle that the lens assembly 110 rotates relative to the initial state of the camera module can be obtained by combining the relative rotation angle of the lens assembly 110 and the module bracket 400 detected by the angle detection piece, and therefore, the lens assembly 110 can be rotated back to the initial state by controlling the magnitude and the direction of the current introduced into the conductive piece 210, the relative angle between the lens assembly 110 and a view finding area can be kept unchanged all the time, and the anti-shake purpose is realized.

When adopting above-mentioned technical scheme, the measurement work of the absolute rotation angle of lens subassembly 110 can be assisted the completion with the help of the device of standard allocation in the electronic equipment, can reduce the cost of camera module on the one hand, and on the other hand can reduce the overall dimension 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.

As described above, the angle detecting member may be various, and in the present embodiment, optionally, the angle detecting member includes the varistor 310 and the contact electrode 320, the varistor 310 extends around the optical axis of the lens assembly 110, one of the varistor 310 and the contact electrode 320 is fixedly connected to the lens assembly 110, the other is fixedly connected to the module bracket 400, and the contact electrode 320 is slidably connected to the varistor 310.

Under the condition that the angle detection piece adopts above-mentioned structure, simple structure, the cost is lower, the installation of being convenient for, and the testing result is comparatively accurate. Specifically, similar to the driving assembly, the angle detecting element can also be mounted on a side of the lens assembly 110 away from the light incident side, and the angle detecting element and the driving assembly can be separated from each other to prevent the working processes of the angle detecting element and the driving assembly from affecting each other. The contact electrode 320 and the varistor 310 are connected to a power source, and the angle detector may be provided with a current meter to determine the relative position between the contact electrode 320 and the varistor 310 and thus the relative rotation angle between the lens assembly 110 and the module holder 400 by detecting the magnitude of the current in the circuit.

More specifically, the angle at which the varistor 310 extends in the direction around the optical axis of the lens assembly 110 may be determined as the case may be, and the angle at which the varistor 310 extends in the direction around the optical axis of the lens assembly 110 may be made relatively large, thereby improving the span of the angle detection member.

Based on the above, further, the angle detection member may be disposed around the lens assembly 110, that is, the rheostat 310 may be disposed around a sidewall of the lens assembly 110, the sidewall of the lens assembly 110 being disposed around the optical axis of the lens assembly 110. Under the condition that adopts above-mentioned technical scheme, can make rheostat 310 encircle lens subassembly 110 and set up to the detection range that makes angle detection piece can be close to or even equals 360, and then no matter how big relative rotation angle between lens subassembly 110 and the module support 400, all can detect aforementioned relative rotation angle through angle detection piece, promotes angle detection piece's application scope.

Alternatively, the driving assembly may also be disposed on a sidewall of the lens assembly 110, and the sidewall of the lens assembly 110 is disposed around the optical axis of the lens assembly 110. Under the condition of adopting the technical scheme, the moment arm formed by the action point between the driving component and the lens component 110 (and the module bracket 400) can be longer, so that the driving component can drive the lens component 110 and the module bracket 400 to rotate relatively by applying smaller force; moreover, under the condition of adopting the above technical scheme, the conductive piece 210 and the magnetic piece 220 can be prevented from being acted by the force along the optical axis direction of the lens component 110 as much as possible, the working reliability of the driving component is improved, and the service life of the driving component is further prolonged.

Optionally, the number of the driving assemblies is multiple, and the multiple driving assemblies are uniformly and alternately disposed on the periphery of the lens assembly 110, in this case, on one hand, the magnitude of the driving force applied to the lens assembly 110 can be increased, and on the other hand, each position on the lens assembly 110 can be subjected to a relatively consistent driving force, so that the lens assembly 110 is not deflected basically in the rotating process, and the lens assembly 110 is ensured to be able to stably rotate relative to the module bracket 400. The number of the driving components can be determined according to actual requirements, and a plurality of driving components can work together under the condition that the lens assembly 110 needs to be driven to rotate relative to the module bracket 400.

Alternatively, the plurality of driving assemblies may be operated separately by arranging the relative positions of the conductive member 210 and the magnetic member 220 in the plurality of driving assemblies, for example, in the plurality of driving assemblies, a first driving assembly may drive the lens assembly 110 to rotate about the optical axis of the lens assembly 110 in a first direction relative to the module holder 400, at this time, the lens assembly may drive the conductive member in the second driving assembly to move between the first magnetic pole and the second magnetic pole of the magnetic member in the second driving assembly, by electrifying the conductive member in the second driving assembly, the lens assembly 110 may be driven to continue to rotate about the optical axis of the lens assembly 110 in the first direction relative to the module holder 400, and so on, by separately operating the plurality of driving assemblies, the relative rotation angle between the lens assembly 110 and the module holder 400 may be made larger, and the anti-shake range of the camera module may be improved, thereby improving the user experience. In addition, in the above technical solution, the first magnetic pole and the second magnetic pole of the magnetic member may be relatively small in size.

As described above, the magnetic member 220 may be a single magnet, or may be two magnets, which may be an electromagnet or a permanent magnet. As shown in fig. 6, the magnetic member 220 may be a bar magnet, and in this case, the conductive member 210 may be disposed in the magnetic member 220 at a position close to the first magnetic pole 221, that is, a distance between the conductive member 210 and an end surface of the first magnetic pole 221 is smaller than a distance between the conductive member 210 and an end surface of the second magnetic pole 222. When the conductive element 210 is located at the above position, since the direction of the magnetic field has a component along the length direction of the bar magnet (i.e. the linear direction of the direction in which the first magnetic pole 221 points to the second magnetic pole 222), it can also be ensured that the conductive element 210 in the energized state can move in the magnetic field, and the specific moving direction of the conductive element 210 includes a direction approaching to the first magnetic pole 221 or a direction departing from the first magnetic pole 221.

In another embodiment of the present application, as shown in fig. 7, the magnetic member 220 is a U-shaped magnet, i.e., a horseshoe magnet, which includes a first magnetic pole 221 and a second magnetic pole 222 that are different, and the conductive member 210 is disposed between the first magnetic pole 221 and the second magnetic pole 222 of the U-shaped magnet. In the U-shaped magnet, a portion of the first magnetic pole 221 and a portion of the second magnetic pole 222 are disposed in a mutually profiling manner, and the profiled portions of the first magnetic pole 221 and the second magnetic pole 222 have a certain size, so that a magnetic field with a large range can be provided for the conductive member 210, and the adjustment range of the driving assembly can be further expanded.

Further, the first magnetic pole 221 and the second magnetic pole 222 of the U-shaped magnet may be arc-shaped structures, which may make the movement of the conductive component 210 between the first magnetic pole 221 and the second magnetic pole 222 more stable. In addition, compared with an electromagnet, the U-shaped magnet can provide a stable magnetic field, is relatively low in cost, convenient to install and manufacture and high in reliability.

As described above, a connection member such as a rotation shaft may be provided between the lens assembly 110 and the module holder 400, so that the operational stability between the lens assembly 110 and the module holder 400 is relatively high. In another embodiment of the present application, optionally, the camera module may further include a sliding assembly, the sliding assembly includes a sliding groove 410 and a sliding block 150, one of the sliding groove 410 and the sliding block 150 is disposed on the lens assembly 110, and the other is disposed on the module holder 400, and the sliding block 150 and the sliding groove 410 are slidably engaged in an axial direction around the lens assembly 110, so that the lens assembly 110 and the module holder 400 form a more stable connection and engagement relationship under the action of the sliding assembly.

Specifically, the angle of the slide groove 410 extending in the direction around the optical axis of the lens assembly 110 may be determined according to the actual conditions such as the adjustment capability of the driving assembly. Optionally, the sliding groove 410 and the sliding block 150 are disposed on a side of the lens assembly 110 facing away from the light incident side, and the sliding block 150 may be fixed on the lens assembly 110, such that the sliding groove 410 is disposed on the module bracket 400, thereby preventing the lens assembly 110 from being damaged due to the need to dispose the sliding groove 410. The sliding block 150 may be a strip-shaped segment-shaped structural member, or the sliding block 150 may be an arc-shaped segment-shaped structural member, and the sliding block 150 and the lens assembly 110 may be fixed to each other by bonding or connecting members.

Further, as shown in fig. 8, the sliding groove 410 may include a first groove 411 and a second groove 412, the first groove 411 and the second groove 412 are communicated with each other, and the slider 150 includes a first block and a second block, which are connected to each other. Specifically, the first block and the second block may be formed in an integrated manner to improve the structural stability of the slider 150. The first block is slidably disposed in the first slot 411, and the second block is slidably disposed in the second slot 412, so as to ensure that the sliding block 150 and the sliding groove 410 can form a sliding fit in the direction of the optical axis of the lens assembly 110.

In addition, in the optical axis of the lens assembly 110 and/or the direction perpendicular to the optical axis of the lens assembly 110, the size of the first slot 411 may be smaller than the size of the second slot 412, and the second block may be in limit fit with the first slot 411. Under the condition, the sliding block 150 can be prevented from being separated from the sliding groove 410 in the working process of the camera assembly, and the sliding fit relation between the sliding block 150 and the sliding groove 410 is ensured to be stable.

In the case of adopting the sliding block 150 and the sliding groove 410 of the structure provided by the above embodiment, the sliding groove 410 may be provided on the module bracket 400, and by providing the sliding groove 410 with another communicating structure, the second block may be installed into the second groove 412 through the aforementioned communicating structure, and the first block may be installed into the first groove 411 through the aforementioned communicating structure; meanwhile, by providing the blocking structure detachably connected to the module holder 400, the communication structure can be blocked after the slider 150 is mounted in the chute 410, and the slider 150 is prevented from coming off from the communication structure.

To further enhance the supporting effect of the sliding assembly, optionally, the sliding assembly is disposed at the outer periphery of the sidewall of the lens assembly 110. For example, the slide 150 and the slide groove 410 can be annular structures, so that the connection stability between the lens assembly 110 and the module holder 400 is relatively high. In order to reduce the difficulty of assembling the lens assembly 110 and the module holder 400 with the sliding assembly, the sliding blocks 150 may be arc-shaped segment-shaped structures, and the number of the sliding blocks 150 may be multiple, and the shapes of the multiple sliding blocks 150 may be the same, so as to reduce the difficulty of spare parts. The plurality of sliders 150 are spaced apart from each other in the direction around the optical axis of the lens assembly 110, so that the lens assembly 110 can be stably and rotatably coupled to the module holder 400.

As described above, the number of the driving components may be multiple, and optionally, as shown in fig. 6 and 7, the number of the sliding components and the number of the driving components are multiple, and the multiple sliding components and the multiple driving components are alternately arranged along the direction around the optical axis of the lens component 110, so that the stability of the connection relationship between the lens component 110 and the module bracket 400 can be further improved, and the driven effect at various places on the lens component 110 can be ensured to be substantially the same, and the relative rotation process between the lens component 110 and the module bracket 400 can be ensured to be smoother.

As described above, the angle detecting member may include the varistor 310 and the contact electrode 320, the varistor 310 may be disposed on a side of the lens assembly 110 facing away from the light incident side, or the varistor 310 may be disposed around a side wall of the lens assembly 110. In the case where the lens assembly 110 is coupled to the module holder 400 by the slide assembly and the slider 150 is disposed outside the sidewall of the lens assembly 110, optionally, as shown in fig. 4 and 8, the varistor 310 is disposed in the slide groove 410 and the contact electrode 320 is disposed on the slider 150. In particular, the varistor 310 may be disposed in the second groove 412 in the chute 410, and correspondingly, the contact electrode 320 may be disposed on the second block. Further, the varistor 310 may be disposed on a sidewall of the second slot 412 facing away from the lens assembly 110, which may further promote stability of the fit between the contact electrode 320 and the varistor 310.

Under the condition of adopting the technical scheme, the contact electrode 320 can move in the sliding groove 410 along with the sliding block 150, and the contact electrode 320 can be ensured to be stably connected with the rheostat 310, so that the aim of detecting the relative rotation angle between the lens assembly 110 and the module bracket 400 is fulfilled. Moreover, when the technical scheme is adopted, the angle detection piece and the sliding component can be arranged outside the side wall of the lens component 110, the angle detection piece and the sliding component can be ensured not to be mutually obstructed, and the installation space occupied by the angle detection piece and the sliding component can be reduced to a certain extent; meanwhile, the assembly work of the angle detection piece can be carried out along with the assembly work of the sliding assembly, so that the difficulty of assembling the angle detection piece and the sliding assembly can be reduced, and the assembly efficiency can be improved; in addition, the sliding slot 410 and the sliding block 150 are limited to each other, which can provide guarantee for the matching relationship between the contact electrode 320 and the varistor 310, and prevent the separation phenomenon from occurring during the relative sliding process between the contact electrode 320 and the varistor 310, which can not normally measure the relative rotation angle between the lens assembly 110 and the module holder 400.
