Description

Technical Field

[0001] This utility model relates to the field of lens technology, and more specifically, to a lens driving device, a camera module, and an electronic device. Background Technology

[0002] As consumers' demand for mobile phone photography increases, the functions of mobile phone cameras (i.e., camera modules) are becoming more and more abundant. Features such as portrait shooting, telephoto shooting, optical zoom, and optical image stabilization are all integrated into cameras with limited space. Among them, functions such as autofocus, optical image stabilization, and optical zoom often rely on optical actuators (motors) to achieve their functions.

[0003] Structurally, the lens is fixed to the motor's carrier, which is a movable part. This carrier typically moves the lens along the optical axis under the action of the motor's drive components to achieve focusing. For camera modules with optical image stabilization (OIS), the motor often has a more complex structure. This is because, in addition to driving the lens along the optical axis, the motor also needs to drive the lens to move in other degrees of freedom (e.g., perpendicular to the optical axis: X-axis and Y-axis) to compensate for camera shake during shooting. Furthermore, existing motors with focusing and image stabilization functions have upgraded closed-loop control, requiring different detection elements for displacement detection in different degrees of freedom. These detection elements need to be connected to external circuits, making the overall structure and circuit layout more complex. This poses a challenge to the miniaturization of the overall structure, reduces structural reliability, increases structural cost, and ultimately affects motor performance.

[0004] Therefore, the existing technology suffers from poor performance of the driving device for the camera module. Utility Model Content

[0016] Furthermore, at least one anti-collision protrusion is provided on the side of the frame assembly near the bottom surface of the base; and / or a reinforcing plate is embedded inside the frame assembly.

[0018] According to another aspect of the present invention, a camera module is provided, including the lens driving device described above.

[0019] According to another aspect of the present invention, an electronic device is provided, including the camera module described above.

[0020] Applying the technical solution of this utility model, the lens driving device in this application includes a housing assembly, a frame assembly, a first driving magnet, a first driving coil, a second driving magnet, a second driving coil, a first detection element, and a second detection element. The housing assembly has a receiving cavity; a lens support; the frame assembly is movably disposed within the receiving cavity, the lens support is disposed on the frame assembly and can move along the X-axis or Y-axis with the frame assembly, and the lens support can move relative to the frame assembly along the Z-axis; the first driving magnet is disposed on the lens support; the first driving coil is disposed on the housing assembly corresponding to the first driving magnet; there are at least two second driving magnets disposed on the frame assembly; there are at least two second driving coils disposed on the housing assembly corresponding to the second driving magnet; the first detection element is disposed on the housing assembly corresponding to the first driving magnet; and the second detection element is disposed on the housing assembly corresponding to the second driving magnet.

During the movement of the lens support together with the frame assembly, since the first detection element is located on the housing assembly, the displacement detection of the lens in the X-axis and Y-axis directions can be achieved through the cooperation of the first detection element with the first driving magnet and the cooperation of the second detection element with one of the two second driving magnets. When the first driving coil is energized, since the first driving magnet is located on the lens support, the lens support can move relative to the frame assembly along the Z-axis under the interaction of the first driving coil and the first driving magnet, thereby achieving lens focusing. During the movement of the lens support relative to the frame assembly, the displacement of the lens in the Z-axis direction can be detected through the cooperation of the first detection element and the first driving magnet. Therefore, compared with the driving devices of camera modules in the prior art, the lens driving device in this application can realize the displacement detection of the lens in the X, Y, and Z axes through two detection elements, namely the first and second detection elements. This reduces the number of detection elements used and optimizes the internal structure of the lens driving device, while also reducing the overall weight of the lens driving device. Therefore, the lens driving device in this application effectively solves the problem of poor performance of the driving devices of camera modules in the prior art. Attached Figure Description

[0037] To address the issue of poor performance in the driving devices of existing camera modules, this application provides a lens driving device, a camera module, and an electronic device.

[0038] The camera module in this application has the lens driving device described below, and the electronic device in this application has a camera module. Furthermore, the electronic device can be a smartphone, tablet computer, drone, or handheld camera, etc.

[0039] like Figures 1 to 9 As shown, the lens driving device in this application includes a housing assembly 10, a frame assembly 30, a first driving magnet 40, a first driving coil 41, a second driving magnet 50, a second driving coil 51, a first detection element 60, and a second detection element 70. The housing assembly 10 has a receiving cavity 11; a lens support 20; a frame assembly 30 movably disposed within the receiving cavity 11, the lens support 20 being disposed on the frame assembly 30 and capable of moving along the X-axis or Y-axis with the frame assembly 30, and the lens support 20 being capable of moving relative to the frame assembly 30 along the Z-axis; a first driving magnet 40 being disposed on the lens support 20; a first driving coil 41 being disposed on the housing assembly 10 corresponding to the first driving magnet 40; at least two second driving magnets 50 being disposed on the frame assembly 30; at least two second driving coils 51 being disposed on the housing assembly 10 corresponding to the second driving magnets 50; a first detection element 60 being disposed on the housing assembly 10 corresponding to the first driving magnet 40; and a second detection element 70 being disposed on the housing assembly 10 corresponding to the second driving magnets 50.

[0040] When using the lens driving device of this application, the lens support 20 is used to mount the lens. Since the lens support 20 can move together with and relative to the frame assembly 30, when the second driving coil 51 is energized, the second driving magnet 50 is disposed on the frame assembly 30. Therefore, under the interaction of the second driving coil 51 and the second driving magnet 50, the frame assembly 30 can drive the lens support 20 to move along the X-axis or Y-axis. That is, the frame assembly 30 can drive the lens support 20 to move in the XY plane, thereby achieving lens image stabilization adjustment. During the process of the frame assembly 30 driving the lens support 20 together, since the first detection element 60 is disposed on the housing assembly 10, the displacement detection of the lens in the X-axis and Y-axis directions can be achieved through the cooperation of the first detection element 60 with the first driving magnet 40 and the cooperation of the second detection element 70 with one of the two second driving magnets 50. When the first driving coil 41 is energized, the first driving magnet 40 is mounted on the lens support 20. Therefore, the lens support 20 can move relative to the frame assembly 30 along the Z-axis direction under the interaction of the first driving coil 41 and the first driving magnet 40, thereby achieving lens focusing. During the movement of the lens support 20 relative to the frame assembly 30, the displacement of the lens in the Z-axis direction can be detected through the cooperation of the first detection element 60 and the first driving magnet 40. Therefore, compared with the driving devices of existing camera modules, the lens driving device of this application can achieve displacement detection of the lens in the X, Y, and Z axes through two detection elements, the first detection element 60 and the second detection element 70. This reduces the use of detection elements, optimizes the internal structure of the lens driving device, and also reduces the overall weight of the lens driving device. Therefore, the lens driving device of this application effectively solves the problem of poor performance in the driving devices of existing camera modules.

[0041] Furthermore, in this application, both the first detection element 60 and the second detection element 70 can be Hall elements.

[0042] In one specific embodiment of this application, there are two second driving magnets 50. One second driving magnet 50 is parallel to the first driving magnet 40, and the other second driving magnet 50 is opposite to the second detection element 70 and perpendicular to the first driving magnet 40. Furthermore, in this embodiment, the projection of the frame assembly 30 in the Z-axis direction is approximately rectangular. Therefore, the two second driving magnets 50 are disposed on two adjacent sidewalls of the frame assembly 30.

[0043] Furthermore, in the embodiments described below, one of the second driving magnets 50 extends along the X-axis direction, or in other words, the sidewall of the frame assembly 30 containing this second driving magnet 50 is parallel to the X-axis. The other second driving magnet 50 extends along the Y-axis direction and is opposite to the first driving magnet 40, or in other words, the sidewall of the frame assembly 30 containing this second driving magnet 50 is parallel to the sidewall of the frame assembly 30 corresponding to the first driving magnet 40 and to the Y-axis. Therefore, in this embodiment, the first detection element 60 can detect the displacement of the lens along the X-axis and Z-axis directions, while the second detection element 70 can detect the displacement of the lens along the Y-axis direction. Furthermore, in this embodiment, the first driving magnet 40 and the first driving coil 41 are spaced apart and arranged opposite each other along the X-axis direction.

[0044] Optionally, the frame assembly 30 is provided with a clearance opening 31 corresponding to the first driving magnet 40. At least a portion of the first driving coil 41 is located in the clearance opening 31, and there is a clearance gap between the periphery of the first driving coil 41 and the circumferential inner wall of the clearance opening 31. This arrangement effectively reduces the distance between the first driving coil 41 and the first driving magnet 40, thereby effectively improving the induction effect between them. Furthermore, since the first driving coil 41 does not move with the frame assembly 30 during the movement of the frame assembly 30 and the lens support 20 in the XY plane, the clearance gap effectively prevents collisions between the first driving coil 41 and the frame assembly 30. Moreover, the clearance gap between the first driving coil 41 and the circumferential inner wall of the clearance opening needs to be greater than the stroke of the frame assembly 30 when it drives the lens support 20 in anti-shake motion. Alternatively, the clearance size is set based on the maximum movement distance of the frame component 30, and the clearance needs to be greater than the maximum movement distance of the frame component 30.

[0045] Optionally, the frame assembly 30 is provided with a mounting notch 32 corresponding to the second driving magnet 50, and the second driving magnet 50 is disposed at the mounting notch 32. This arrangement can effectively ensure a more compact internal structure of the lens driving device.

[0046] Optionally, such as Figure 6 and Figure 9 As shown, the first driving magnet 40 is a multi-pole magnetized magnet or a Hellbeck array magnet. In a specific embodiment of this application, the first driving magnet 40 is a multi-pole magnetized magnet and includes at least two magnetic regions 42 arranged along the Z-axis, and the polarization directions of adjacent magnetic regions 42 are opposite and perpendicular to the Z-axis. This arrangement ensures that the first driving magnet 40 can be effectively detected by the first detection element 60 when the lens support 20 moves relative to the frame assembly 30 along the Z-axis, thereby ensuring the performance of the lens driving device.

[0047] Of course, in this application, the second driving magnet 50 can also be a multi-pole magnetized magnet or a Hellbeck array magnet. Furthermore, in addition to the above-described configuration, the first driving magnet 40 and the second driving magnet 50 can also be composed of multiple sub-magnets.

[0048] Optionally, the lens driving device further includes a guide slide shaft 80. At least one guide slide shaft 80 is provided at each end of the sidewall opposite to the first driving magnet 40 of the frame assembly 30, and the guide slide shaft 80 extends along the Z-axis. Furthermore, in this application, the slide shaft can be supported by a ceramic material. When the lens support 20 moves relative to the frame assembly 30 along the Z-axis, the guide slide shaft 80 can guide and limit the movement of the lens support 20, ensuring that the movement direction of the lens support 20 is parallel to the Z-axis and does not deviate relative to the optical axis. Preferably, the lens support 20 is provided with a guide groove corresponding to the guide slide shaft 80, and a portion of the guide slide shaft 80 is located inside the guide groove. Thus, when the lens support 20 moves relative to the frame assembly 30, the guide slide shaft 80 can move along the guide groove to limit and guide the lens support 20. Of course, in this application, multiple ball bearings can also be used instead of the guide slide shaft, and the multiple ball bearings are divided into multiple groups, with the multiple ball bearings in each group arranged along the Z-axis.

[0049] Optionally, the lens driving device further includes a first magnetic chuck 90, which is disposed on the side of the first driving coil 41 away from the first driving magnet 40. This arrangement ensures that the lens support 20 can rest against the first magnetic chuck 90 under the interaction of the first driving magnet 40 and the first magnetic chuck 90, or in other words, that the lens support 20 can rest against the side wall of the frame assembly 30 with the guide slide shaft 80. This improves the contact between the lens support 20 and the guide slide shaft 80, thereby ensuring the limiting and guiding effect of the guide slide shaft 80 on the lens support 20.

[0050] In one specific embodiment of this application, the housing assembly 10 includes a base 12 and a housing 13. A second driving coil 51 and a second detection element 70 are respectively disposed on the base 12. The housing 13 covers the base 12 and forms a receiving cavity 11 with the base 12. The first driving coil 41 and the first detection element 60 are respectively disposed on the circumferential inner sidewall of the housing 13. Furthermore, in this application, the first driving magnet 40 can be considered as side-standing, while the second driving magnet 50 can be considered as lying flat, thereby ensuring that the first driving magnet 40 can better sense the first driving coil 41 disposed on the circumferential sidewall of the housing 13, and ensuring that the second driving magnet 50 can better sense the second driving coil 51 disposed on the base 12.

[0051] Optionally, at least one anti-collision protrusion 33 is provided on the side of the frame assembly 30 near the bottom surface of the base 12. With this arrangement, when the lens drive device is subjected to an external impact or vibrates unexpectedly, the anti-collision protrusion 33 can provide a certain buffering effect on the lens support 20.

[0052] Optionally, a reinforcing plate is embedded inside the frame assembly 30. This arrangement effectively increases the strength of the frame assembly 30, thereby improving its performance.

[0053] Of course, the lens driving device in this application also includes an upper cover 200, which is disposed on the side of the frame assembly 30 away from the base 12. By providing the upper cover 200, the movement of the lens support 20 in the Z-axis direction can be limited to a certain extent.

[0054] Optionally, a mounting boss 121 is provided at the corner of the corresponding frame assembly 30 of the base 12. The mounting boss 121 has a mounting groove 122. The lens driving device also includes a ball bearing 100, at least a portion of which is located in the mounting groove 122. In a specific embodiment of this application, four mounting bosses 121 are provided at the four corners of the corresponding frame assembly 30 of the base 12, and each mounting boss 121 has a mounting groove 122. At least one ball bearing 100 is provided in each mounting groove 122, thereby effectively reducing the friction between the frame assembly 30 and the base 12 during the movement of the lens support 20 driven by the frame assembly 30. Further optionally, the lens driving device also includes a second magnetic absorbing piece 91, which is located on the side of the second driving coil 51 away from the second driving magnet 50. This arrangement ensures better contact between the frame assembly 30 and the ball bearing 100. Of course, in this application, a reinforcing plate is also embedded in the part where the frame assembly 30 contacts the ball bearing 100.

[0055] Furthermore, the lens driving device in this application also includes four springs 300. Each spring 300 is located at one of the four corners of the frame assembly 30, with one end connected to the frame assembly 30 and the other end connected to the column 123 of the base 12. This allows the springs 300 to provide anti-torsional support to the frame assembly 30 during its movement relative to the housing assembly 10. Simultaneously, the base 12 has four columns 123 corresponding to the four springs 300.

[0057] 1. Effectively solves the problem of poor performance of the driving device of the camera module in the existing technology;
