Abstract
Description
Technical Field
[0001] This application belongs to the field of camera module technology, specifically relating to a camera module and an electronic device. Background Technology
[0002] In related technologies, a camera module includes a lens and an imaging chip. Image stabilization is achieved by rotating the lens relative to the imaging chip. However, if the angle of rotation between the lens and the imaging chip is too large, the image quality of the camera module will be reduced. Therefore, a carrier can also be used to support both the lens and the imaging chip simultaneously, and image stabilization can be achieved by driving the carrier to rotate. However, since the carrier, imaging chip, and lens rotate simultaneously, the clearance required for the carrier's movement is large, resulting in a larger overall size of the camera module. Summary of the Invention
[0003] This application aims to provide a camera module and electronic device that can solve the problem that the large clearance required during the movement of the carrier leads to a large overall size of the camera module.
[0004] To solve the above-mentioned technical problems, this application is implemented as follows:
[0005] In a first aspect, embodiments of this application propose a camera module, including a gimbal assembly and a lens module; the gimbal assembly includes a base, a carrier, and a support, the carrier is rotatably connected to the base, the carrier is provided with a mounting hole, the support is disposed on a first side of the carrier in the axial direction, and the support is arranged around the mounting hole; the lens module is disposed in the mounting hole and is capable of sliding relative to the carrier in the axial direction; wherein, at least a portion of the sidewall of the support is closer to the optical axis of the lens module than the sidewall of the carrier.
[0006] Secondly, embodiments of this application propose an electronic device, including a housing and a camera module as described in any of the above technical solutions, wherein the camera module is disposed in the housing.
[0007] In the embodiments of this application, the camera module includes a gimbal assembly and a lens module. The gimbal assembly includes a base and a carrier, which are rotatably connected to the base. The carrier is provided with a mounting hole, and the lens module is disposed in the mounting hole, thereby supporting the lens module through the carrier. Furthermore, since the carrier is rotatably connected to the base, image stabilization can be achieved by driving the carrier and the lens module to move.
[0008] The gimbal assembly also includes a support unit, which is located on the first side of the carrier in the axial direction. The support unit is arranged around the mounting hole, and the lens module can slide relative to the carrier in the axial direction. By setting the support unit, the lens module can have a longer sliding distance in the axial direction, thereby enabling the camera module to have a certain zoom ratio and improving the shooting effect of the camera module.
[0009] At least a portion of the sidewalls of the support are closer to the optical axis of the lens module relative to the sidewalls of the carrier, creating a notch at the top of the carrier. This reduces the space the carrier traverses during rotation, thus reducing the required clearance within the camera module and consequently decreasing its size, which is beneficial for miniaturization. Furthermore, by setting at least a portion of the sidewalls of the support closer to the optical axis of the lens module relative to the sidewalls of the carrier, compared to having the entire sidewall of the carrier aligned with the optical axis, the carrier achieves higher strength without increasing the space required for movement. This enhances the stability of the carrier's support for the lens module, further improving the image stabilization effect of the camera module.
[0010] The electronic device includes a housing and a camera module as described in any of the above technical solutions. Therefore, the electronic device possesses all the beneficial effects of the camera module as described in any of the above technical solutions, which will not be elaborated here.

[0028] The following is combined Figures 1 to 9 This application describes a camera module 10 and an electronic device according to embodiments thereof.
[0029] like Figure 1 and Figure 2 As shown, a camera module 10 according to some embodiments of this application includes a gimbal assembly 100 and a lens module 200; the gimbal assembly 100 includes a base 110, a carrier 120, and a support 130, the carrier 120 being rotatably connected to the base 110, the carrier 120 being provided with a mounting hole 122, and the support 130 being disposed on the carrier 120 in the axial direction (…). Figure 1 On the first side (in the direction indicated by the middle arrow A), the support portion 130 is arranged around the mounting hole 122; the lens module 200 is disposed in the mounting hole 122 and can slide axially relative to the carrier 120; wherein, at least a portion of the sidewall 132 of the support portion 130 is closer to the optical axis of the lens module 200 than the sidewall 124 of the carrier 120.
[0030] According to an embodiment of this application, the camera module 10 includes a gimbal assembly 100 and a lens module 200. The gimbal assembly 100 includes a base 110 and a carrier 120. The carrier 120 is rotatably connected to the base 110. The carrier 120 is provided with a mounting hole 122. The lens module 200 is disposed in the mounting hole 122, thereby supporting the lens module 200 through the carrier 120. Furthermore, since the carrier 120 is rotatably connected to the base 110, image stabilization can be achieved by driving the carrier 120 and the lens module 200 to move.
[0031] The gimbal assembly 100 also includes a support 130, which is disposed on the first side of the carrier 120 in the axial direction. The support 130 is arranged around the mounting hole 122. The lens module 200 can slide relative to the carrier 120 in the axial direction. By setting the support 130, the lens module 200 has a longer sliding distance in the axial direction, thereby enabling the camera module 10 to have a certain zoom factor and improving the shooting effect of the camera module 10.
[0032] At least a portion of the sidewall 132 of the support portion 130 is closer to the optical axis of the lens module 200 relative to the sidewall 124 of the carrier 120, forming a notch at the top of the carrier 120. This reduces the space traversed by the carrier 120 during rotation, thus reducing the required clearance space inside the camera module 10 and consequently decreasing its size, which is beneficial for miniaturization. Furthermore, by setting at least a portion of the sidewall 132 of the support portion 130 closer to the optical axis of the lens module 200 relative to the sidewall 124 of the carrier 120, compared to the entire sidewall 124 of the carrier 120 being closer to the optical axis, the carrier 120 exhibits higher strength without increasing the space required for its movement. This enhances the stability of the carrier 120 in supporting the lens module 200, further improving the image stabilization effect of the camera module 10.
[0033] Specifically, compared with the solution where the carrier 120 does not have a support portion 130, the technical solution provided in this application results in a shorter movement space for the lens module 200 and a smaller zoom ratio for the camera module 10. However, by providing a support portion 130 with its sidewall recessed towards the optical axis, the lens module 200 can have a longer movement space, and the movement of the carrier 120 will not occupy too much space inside the camera module 10, thus facilitating the miniaturization of the camera module 10.
[0034] Compared with the solution where the sidewall 124 of the carrier 120 is generally close to the optical axis, the technical solution provided in this application has a more stable support capability, thereby improving the stability of the camera module 10 during the image stabilization process.
[0035] Optionally, the sidewalls of the areas where the support 130 and the carrier 120 are opposite to the four corners are closer to the optical axis of the lens module 200 than the sidewalls 124 of the carrier 120.
[0036] The side wall 132 of the support 130 is closer to the optical axis of the lens module 200 than the side wall 124 of the carrier 120.
[0037] According to some embodiments of this application, such as Figure 1 and Figure 2 As shown, the lens module 200 includes a guide component 210, a lens 220, and an imaging component 230; the guide component 210 is disposed in the mounting hole 122, and the lens module 200 and the carrier 120 are slidably connected through the guide component 210; the lens 220 is connected to the guide component 210; the imaging component 230 is disposed on the light-emitting side of the lens 220 and is connected to the carrier 120.
[0038] In this embodiment, the lens module 200 includes a guide component 210 and a lens 220. The guide component 210 is disposed within the mounting hole 122 and is slidably connected to the carrier 120. The lens 220 is connected to the guide component 210, thereby enabling the lens 220 to slide relative to the carrier 120. The guide component 210 guides the sliding direction of the lens 220, improving the stability of the lens 220 during movement. The lens module 200 also includes an imaging component 230, which is disposed on the light-emitting side of the lens 220 and connected to the carrier 120. Since the lens 220 can move relative to the carrier 120, it can also move relative to the imaging component 230, thereby adjusting the distance between the lens 220 and the imaging component 230 and achieving optical zoom of the camera module 10. Both the imaging component 230 and the lens 220 are mounted via the carrier 120. When the camera module 10 is stabilizing, the carrier 120 can simultaneously rotate the lens 220 and the imaging component 230 together, thereby preventing the lens 220 from rotating relative to the imaging component 230. This ensures that the optical axis of the lens 220 is perpendicular to the image sensor, avoiding the problem of shadows in the image under large-angle stabilization conditions and improving the image quality of the image sensor.
[0039] Optionally, the imaging component 230 is a photosensitive chip.
[0040] Optionally, the lens module 200 also includes a first cover plate 270, which covers the side of the lens 220 away from the imaging component 230 to protect the internal structure of the lens module 200.
[0041] Lens 220 is used to converge light.
[0042] According to some embodiments of this application, such as Figure 1 and Figure 2 As shown, the camera module 10 also includes a first magnetic element 310 and a first driving coil 320; the first magnetic element 310 is disposed between the guide component 210 and the carrier 120 and is connected to the guide component 210; the first driving coil 320 is disposed on the inner side of the carrier 120, is connected to the carrier 120, and is opposite to the first magnetic element 310, for driving the lens module 200 to slide relative to the carrier 120.
[0043] In this embodiment, the camera module 10 further includes a first magnetic element 310, which is disposed between the guide component 210 and the carrier 120 and connected to the guide component 210, thereby enabling the installation and fixation of the first magnetic element 310 through the guide component 210. The camera module 10 also includes a first driving coil 320, which is disposed inside the carrier 120 and connected to the carrier 120, thereby enabling the installation and fixation of the first driving coil 320 through the carrier 120. The first driving coil 320 is opposite to the first magnetic element 310. When the first coil is energized, it generates a magnetic field. The first magnetic element 310 is located within this magnetic field, causing it to drive the guide component 210 under the influence of the magnetic field, thus driving the lens module 200. The lens module 200 is driven by the first drive coil 320 in conjunction with the first magnetic component 310, which makes the movement of the lens module 200 more stable and the movement of the lens module 200 more responsive, thereby improving the quality of the camera module 10.
[0044] Optionally, the direction of the magnetic field generated by the first driving coil 320 can be controlled by controlling the direction of the current in the first driving coil 320, thereby realizing the control of the movement direction of the lens module 200.
[0045] According to some embodiments of this application, such as Figure 1 and Figure 2 As shown, the inner wall of the carrier 120 is provided with a sliding groove 126 extending along the axial direction, and the number of sliding grooves 126 is the same as the number of the first drive coils 320; the guide component 210 is provided with a slider 212, which is embedded in the sliding groove 126.
[0046] In this embodiment, the inner wall of the carrier 120 is provided with an axially extending groove 126. The guide component 210 is provided with a slider 212, which is embedded in the groove 126. The slider 212 and the groove 126 cooperate to guide the movement of the lens 220, thereby improving the stability of the zoom process of the camera module 10. The number of grooves 126 is the same as the number of first drive coils 320, which makes the number of grooves 126 match the number of first drive coils 320, reducing the space occupied by the grooves on the inner wall of the carrier 120 and improving the convenience of arranging the first drive coils 320.
[0047] Optionally, the lens module 200 also includes a ball bearing disposed within the slide groove 126, located between the slider 212 and the inner wall of the slide groove 126, thereby reducing the frictional force of the slider 212 relative to the slide groove 126 during movement. This ensures smooth sliding while reducing wear on the slider 212 and the slide groove 126, and improves the guiding accuracy of the guide component 210 in guiding the movement of the lens 220.
[0048] According to some embodiments of this application, such as Figure 1 and Figure 2 As shown, the inner wall of the carrier 120 is provided with a sliding groove 126 extending along the axial direction. The number of sliding grooves 126 is at least two, and at least two sliding grooves 126 are respectively provided on the first drive coil 320 in the circumferential direction. Figure 1 On both sides of the direction indicated by the middle arrow E.
[0049] In this embodiment, there are at least two slide grooves 126. The at least two slide grooves 126 are respectively disposed on both sides of the first drive coil 320 in the circumferential direction. The first magnetic component 310 opposite to the first drive coil 320 can press the slider 212 into the slide groove 126 under the action of magnetic force, reducing the probability of the slider 212 disengaging from the slide groove 126 and further improving the stability of the focusing process of the camera module 10.
[0050] Optionally, a first soft magnet 280 is provided on the first driving coil 320, thereby strengthening the magnetic field generated by the first driving coil 320 and increasing the driving force of the magnetic field generated by the first driving coil 320 on the first magnetic component 310.
[0051] Optionally, the lens module 200 also includes a first soft magnet 280, which is disposed on the first drive coil 320 to increase the strength of the magnetic field generated by the first drive coil 320, and simultaneously attracts the first magnetic component 310, thereby confining the slider 212 within the slide groove 126 through the carrier 120, making the movement of the carrier 120 more stable.
[0052] The lens module 200 also includes a first circuit board 290, which is a flexible circuit board used to charge the first coil. The first circuit board 290 is made of copper strip, polyimide (PI), and adhesive.
[0053] The carrier 120 is used to protect the internal structure of the lens module 200, and the first circuit board 290 and the first soft magnet 280 are fixed on the carrier 120.
[0054] According to some embodiments of this application, such as Figure 1 and Figure 2As shown, the carrier 120 is disposed within the base 110, and the camera module 10 further includes a second magnetic element 410 and a second driving coil 420; the second magnetic element 410 is disposed between the carrier 120 and the base 110 and is connected to the carrier 120; the second driving coil 420 is disposed on the inner side of the base 110, is connected to the base 110, and is opposite to the second magnetic element 410.
[0055] In this embodiment, the camera module 10 further includes a second magnetic component 410, which is disposed between the carrier 120 and the base 110 and connected to the carrier 120, thereby enabling the installation and fixation of the second magnetic component 410 through the carrier 120.
[0056] The camera module 10 also includes a second drive coil 420, which is disposed on the inner side of the base 110 and connected to the base 110, thereby enabling the installation and fixation of the second drive coil 420 through the base 110.
[0057] The second drive coil 420 is opposite to the second magnetic component 410. When the second drive coil 420 is energized, it generates a magnetic field. Under the influence of the magnetic field generated by the second drive coil 420, the second magnetic component 410 moves, thereby causing the carrier 120 and the lens module 200 to rotate relative to the base 110, thus achieving image stabilization of the camera module 10. By cooperating with the second drive coil 420 and the second magnetic component 410 to drive the lens module 200, the movement of the lens module 200 becomes more stable and the movement of the lens module 200 can be responded to more promptly, thereby improving the quality of the camera module 10.
[0058] Optionally, the direction of the magnetic field generated by the second drive coil 420 can be controlled by controlling the direction of the current in the second drive coil 420, thereby realizing the control of the movement direction of the lens module 200.
[0059] Optionally, there are multiple sets of second drive coils 420 and multiple second magnetic elements 410. The multiple second magnetic elements 410 are respectively arranged on two adjacent sidewalls of the carrier 120, and the multiple second magnetic elements 410 are arranged opposite to the multiple second drive coils 420.
[0060] There are two sets of second drive coils 420 and two second magnetic elements 410. The two second drive coils 420 and the two second magnetic elements 410 are respectively opposite to each other, thereby driving the carrier 120 to rotate in two directions.
[0061] Optionally, the second magnetic element 410 is disposed on the outer wall of the carrier 120, and the first driving coil 320 is disposed on the inner wall of the carrier 120, so that the fixed part 520 of the lens module 200 and the movable part 510 of the gimbal assembly 100 are integrated into one structure, further reducing the volume of the camera module 10.
[0062] According to some embodiments of this application, such as Figure 1 and Figure 2 As shown, the support portion 130 extends in a ring shape.
[0063] In this embodiment, the support portion 130 extends in a ring shape, so that the circumferential sidewall of the support portion 130 can move closer to the optical axis of the lens module 200, thereby further reducing the space occupied by the carrier 120 when rotating, making the clearance space required inside the camera module 10 smaller, thereby reducing the volume of the camera module 10, which is beneficial to the miniaturization of the camera module 10.
[0064] According to some embodiments of this application, such as Figure 3 and Figure 4 As shown, the camera module 10 also includes a flexible circuit board 500, which includes a movable part 510 and a fixed part 520. The movable part 510 is connected to the fixed part 520 by folding and extends along the outer wall of the base 110 to the imaging component 230 along a predetermined path.
[0065] In this embodiment, the camera module 10 further includes a flexible circuit board 500. The flexible circuit board 500 includes a movable part 510 and a fixed part 520. The movable part 510 is connected to the fixed part 520 by folding and extends along the outer wall of the base 110 to the imaging component 230 along a predetermined path. While providing power to the imaging component 230, the movable part 510 can rotate with the imaging component 230, thereby ensuring the stability of the connection between the imaging component 230 and the flexible circuit board 500. The flexible circuit board 500 extending along the outer wall of the base 110 along a predetermined path reduces the space occupied by the flexible circuit board 500 on the external space of the base 110, further reducing the volume of the camera module 10. The movable part 510 is connected to the fixed part 520 by folding, giving the flexible circuit board 500 more room to move, thereby making the movement of the movable part 510 more flexible and further improving the stability of the camera module 10 during operation.
[0066] Specifically, the first end of the movable part 510 is electrically connected to the imaging component 230. While supplying power to the imaging component 230, the movable part 510 can rotate together with the imaging component 230, thereby ensuring the stability of the connection between the imaging component 230 and the flexible circuit board 500. At least a portion of the movable part 510 extends along the outer wall of the base 110. The fixed part 520 is connected to the second end of the movable part 510. At least a portion of the fixed part 520 overlaps with the movable part 510 and extends along the outer wall of the base 110, so that the flexible circuit board 500 outside the base 110 extends as far as possible along the outer wall of the base 110, thereby reducing the space occupied by the flexible circuit board 500 on the outer space of the base 110 and further reducing the size of the camera module 10. The overlap of at least a portion of the fixed part 520 with the movable part 510 gives the flexible circuit board 500 more room to move, thereby making the movement of the movable part 510 more flexible and further improving the stability of the camera module 10 during operation.
[0067] Specifically, the predetermined path is the path through which the flexible circuit board 500 is arranged on the outside of the base 110, for example, a path extending along the outer wall of the base 110.
[0068] Optionally, the fixing part 520 is fixed to the outer frame of the base 110.
[0069] The flexible circuit board 500 also includes a bending portion 530. The fixing portion 520 is connected to the movable portion 510 through the bending portion 530. To maintain its shape, the bending portion 530 is bonded with a stainless steel sheet or other material with a fixed shape. In order to reduce the reaction force of the flexible circuit board 500 when the camera module 10 moves, the flexible circuit board 500 is bent and lengthened.
[0070] According to some embodiments of this application, such as Figure 5 , Figure 6 and Figure 7 As shown, the gimbal assembly 100 also includes a bracket 170, which is disposed on the base 110 and rotatably connected to the base 110; the carrier 120 is disposed on the bracket 170 and rotatably connected to the bracket 170.
[0071] In this embodiment, the gimbal assembly 100 further includes a bracket 170, which is rotatably connected to the base 110, meaning the bracket 170 can rotate relative to the base 110; the carrier 120 is rotatably connected to the bracket 170, meaning the carrier 120 can rotate relative to the bracket 170. Because the bracket 170 can rotate relative to the base 110, and the carrier 120 can rotate relative to the bracket 170, the carrier 120 can rotate relative to the base 110 around two axes, thereby enabling the gimbal assembly 100 to possess multi-dimensional anti-shake capabilities and improving the anti-shake effect of the gimbal assembly 100.
[0072] Optionally, the gimbal assembly 100 also includes a second cover plate 140 disposed on the base 110 for protecting the internal structure of the gimbal assembly 100.
[0073] The gimbal assembly 100 also includes a third cover plate 150, which is disposed on the side of the base 110 away from the second cover plate 140.
[0074] The gimbal assembly 100 also includes a second circuit board 160, which is composed of copper strip and polyimide (PI). The second coil is fixedly connected to and soldered to the second circuit board 160 for current path. A driver chip may also be provided on the second circuit board 160.
[0075] According to some embodiments of this application, such as Figure 6 , Figure 7 and Figure 8 As shown, the bracket 170 rotates relative to the base 110 about the first axis 250; the carrier 120 rotates relative to the bracket 170 about the second axis 260; the gimbal assembly 100 is projected along the axis of the lens module 200, and the projection of the first axis 250 intersects the projection of the second axis 260.
[0076] In this embodiment, the bracket 170 rotates relative to the base 110 about a first axis 250; the carrier 120 rotates relative to the bracket 170 about a second axis 260; the gimbal assembly 100 is projected along the axial direction of the lens module 200, and the projection of the first axis 250 intersects the projection of the second axis 260. Since the bracket 170 rotates relative to the base 110 about the first axis 250, and the carrier 120 rotates relative to the bracket 170 about the second axis 260, and the projections of the first axis 250 and the second axis 260 intersect along the axial direction of the lens module 200, when the bracket 170 rotates relative to the base 110 about the first axis 250, the bracket 170 can drive the carrier 120 to also rotate relative to the base 110 about the first axis 250; when the carrier 120 rotates relative to the bracket 170 about the second axis 260, the carrier 120 also moves relative to the base 110 about the second axis 260. That is, the carrier 120 can move relative to the base 110 around the first axis 250, and the carrier 120 can also move relative to the base 110 around the second axis. When the carrier 120 rotates in both degrees of freedom at the same time, the combination of the two degrees of freedom makes the carrier 120 have more rotational degrees of freedom relative to the base 110, improving the flexibility of the carrier's rotation relative to the base 110, thereby improving the image stabilization effect of the gimbal assembly 100 on the lens module 200.
[0077] It should be noted that projecting the gimbal assembly 100 along the axis of the lens module 200 means that parallel light rays propagate along the axis of the lens module 200 and illuminate the camera module 10. The projections formed by the first axis 250 and the second axis 260 on the radial plane are the projections of the first axis 250 and the second axis 260.
[0078] Optionally, such as Figure 8 As shown, the bracket 170 is relative to the base 110 about the first axis 250 and about the first direction ( Figure 8 Rotate in the direction indicated by the middle arrow C.
[0079] Carrier 120 relative to support 170 about second axis 260 about second direction ( Figure 8 Rotate in the direction indicated by the middle arrow D.
[0080] Optionally, such as Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the first axis 250 is one diagonal of the bracket 170, and the second axis 260 is the other diagonal of the bracket 170.
[0081] The first axis 250 can be the line connecting two opposite sides of the bracket 170, and the second axis 260 is the line connecting the other two opposite sides of the bracket 170.
[0082] The angle between the first axis 250 and the second axis 260 is greater than or equal to 30 degrees and less than or equal to 60 degrees.
[0083] Optionally, the gimbal assembly 100 further includes a first mounting component connected to the carrier 120. The first mounting component is provided with a first mounting groove. The gimbal assembly 100 also includes a first ball bearing disposed in the first mounting groove. The bracket 170 abuts against the first ball bearing, so that the bracket 170 is rotatably connected to the carrier 120 through the first mounting component and the first ball bearing. This makes the rotation of the carrier 120 relative to the bracket 170 more flexible, further improving the image stabilization effect of the gimbal assembly 100 on the lens module 200.
[0084] Optionally, the first mounting groove is a circular groove with a hollow bottom wall. The inner wall of the first mounting groove matches the shape of the first ball. At least a portion of the first ball is located inside the first mounting groove, and at least a portion of the first ball is exposed outside the first mounting groove.
[0085] Optionally, the gimbal assembly 100 further includes a second mounting component connected to the base 110. The second mounting component is provided with a second mounting groove. The gimbal assembly 100 also includes a second ball bearing disposed in the second mounting groove. The bracket 170 abuts against the second ball bearing, so that the bracket 170 is rotatably connected to the base 110 through the second mounting component and the second ball bearing. This makes the rotation of the bracket 170 relative to the base 110 more flexible, further improving the image stabilization effect of the gimbal assembly 100 on the lens module 200.
[0086] Optionally, the second mounting groove is a circular groove with a hollow bottom wall. The inner wall of the second mounting groove matches the shape of the second ball. At least a portion of the second ball is located inside the second mounting groove, and at least a portion of the second ball is exposed outside the second mounting groove.
[0087] Optionally, the gimbal assembly 100 uses an electromagnetic drive and a ball bearing fulcrum structure to rotate the entire telephoto lens module 200, thereby achieving a large-angle image stabilization function for telephoto lenses. Since the image stabilization does not cause displacement of the optical path and the imaging chip, there is no image stabilization edge shadow problem.
[0088] Optionally, the bracket 170 is a spring-loaded pivot, which can be made of steel or copper alloy and can withstand a certain degree of deformation. The spring-loaded pivot has four elastic grippers 172, each with a protrusion 174. Corresponding positions of the protrusions 174 are recesses, with one pair of recesses located at one corner of the carrier 120 and another pair at one corner of the base 110. The elastic grippers 172 are preloaded, firmly pressing the protrusions 174 into the corresponding recesses, causing sliding friction between the protrusions 174 and the recesses. Two elastic grippers 172 distributed diagonally form the first pivot and the second pivot, respectively. The pivots are positioned at approximately 45° to the X / Y axes of the lens module 200.
