Detailed implementation manners

[0030] The present invention will be described below in conjunction with specific implementation manners.

[0031] Example 1, as Figures 1 to 3 shown, a dual - drive lens includes a base 1, a movable lens mount 2 beside the base 1, the movable lens mount 2 is equipped with a camera lens 3, the base 1 is equipped with a first driving component 4, and the first driving component 4 is drivingly connected to the movable lens mount 2.

[0032] Among them, as Figure 2 and Figure 3 shown, the first driving component 4 includes a first mounting bracket 41 screwed to the base 1, the first mounting bracket 41 is equipped with a first stepping motor 42 and a first driving rotating shaft 43, the power output shaft of the first stepping motor 42 is drivingly connected to the first driving rotating shaft 43, and one end of the movable lens mount 2 is connected to the first driving rotating shaft 43.

[0033] Furthermore, as Figures 3 to 9 shown, the movable lens mount 2 is equipped with a second driving component 5 and a lens mounting seat 6 beside the second driving component 5, the camera lens 3 is installed on the lens mounting seat 6; the second driving component 5 includes a second mounting bracket 51 screwed to the movable lens mount 2, the second mounting bracket 51 is equipped with a second stepping motor 52 and a second driving rotating shaft 53, the power output shaft of the second stepping motor 52 is drivingly connected to the second driving rotating shaft 53, and the lens mounting seat 6 is connected to the second driving rotating shaft 53.

[0034] When the first driving component 4 of the first embodiment drives the movable lens mount 2 to perform a vertical rotation action, the first stepping motor 42 drives the first driving rotating shaft 43 to rotate. The rotating first driving rotating shaft 43 drives the movable lens mount 2 to rotate. Since the movable lens mount 2 is located beside the base 1 and the movable lens mount 2 and the base 1 are arranged at intervals, that is, the rotating first driving rotating shaft 43 can drive the movable lens mount 2 to achieve 360-degree rotation. During the process of the movable lens mount 2 rotating with the first driving rotating shaft 43, the camera lens 3 also rotates synchronously with the movable lens mount 2 to achieve the adjustment of the vertical rotation angle of the camera lens 3.

[0035] When the second driving component 5 of the first embodiment drives the lens mounting seat 6 to perform a horizontal rotation action, the second stepping motor 52 drives the second driving rotating shaft 53 to rotate. The rotating second driving rotating shaft 53 drives the lens mounting seat 6 to rotate. Since the camera lens 3 is mounted on the lens mounting seat 6, during the process of the lens mounting seat 6 rotating with the second driving rotating shaft 53, the camera lens 3 performs the adjustment of the rotation angle in the horizontal direction.

[0036] Based on the above situation, it can be known that through the above structural design, the dual-drive lens of the first embodiment can achieve the adjustment of the vertical and horizontal angles of the camera lens 3, that is, the dual-drive lens of the first embodiment has the advantages of novel structural design and strong adjustability.

[0037] Embodiment 2, as Figures 3 to 9 shown, the difference between the second embodiment and the first embodiment is that: the lens mounting seat 6 is in a cylindrical shape, and a lens mounting chamber 61 is formed inside the lens mounting seat 6. The camera lens 3 is fixedly embedded in the lens mounting chamber 61 of the lens mounting seat 6.

[0038] Among them, the movable lens mount 2 is formed with a mounting seat movable groove 21 having a contour shape consistent with that of the lens mounting seat 6 and in an arc shape. The lens mounting seat 6 is embedded in the mounting seat movable groove 21 of the movable lens mount 2.

[0039] Specifically, the lens mounting seat 6 of the second embodiment is connected to the second driving rotating shaft 53 in the following manner: the lens mounting seat 6 is provided with a mounting seat connecting portion 62 protruding and extending toward the second driving rotating shaft 53. The mounting seat connecting portion 62 is provided with a mounting seat connecting hole 621 opening toward the second driving rotating shaft 53. The end of the second driving rotating shaft 53 is embedded in the mounting seat connecting hole 621 of the mounting seat connecting portion 62. It should be explained that the mounting seat connecting hole 621 can be designed to be flat-shaped. Correspondingly, the end of the second driving rotating shaft 53 is also designed to be flat-shaped. When the end of the second driving rotating shaft 53 is embedded in the mounting seat connecting hole 621 of the mounting seat connecting portion 62, the above flat structure can ensure the anti-rotation connection between the second driving rotating shaft 53 and the lens mounting seat 6.

[0040] During the process of the second driving rotating shaft 53 driven by the second stepping motor 52 driving the lens mounting base 6 to rotate and adjust in the horizontal direction, the second driving rotating shaft 53 drives the entire lens mounting base 6 to rotate in the horizontal direction through the mounting base connecting portion 62 of the lens mounting base 6. Since the mounting base moving slot 21 of the movable lens base 2 is adapted to the contour shape of the lens mounting base 6, on the one hand, the mounting base moving slot 21 of this structural design can position the lens mounting base 6, and on the other hand, it can accurately guide the lens mounting base 6 to perform a horizontal rotation action.

[0041] Embodiment 3, as Figure 2 and Figure 3 shown, the difference between this Embodiment 3 and Embodiment 1 is that: the first mounting bracket 41 is provided with a first reduction gear set 44. The first reduction gear set 44 includes a first input gear 441 and a first gear shaft 442. The first input gear 441 is mounted on the power output shaft of the first stepping motor 42. The first gear shaft 442 includes a first shaft portion and a first gear portion 4421. The first shaft portion of the first gear shaft 442 is mounted on the first mounting bracket 41 through a bearing. The first input gear 441 meshes with the first gear portion 4421 of the first gear shaft 442. The first driving rotating shaft is the first shaft portion of the first gear shaft 442.

[0042] Embodiment 4, as Figure 3 、 Figure 4 、 Figure 6 、 Figure 7 and Figure 8 shown, the second mounting bracket 51 is provided with a second reduction gear set 54. The second reduction gear set 54 includes a second input gear 541, a double gear 542, and a second gear shaft 543. The second gear shaft 543 includes a second shaft portion and a second gear portion 5431. The second shaft portion of the second gear shaft 543 is mounted on the second mounting bracket 51 through a bearing.

[0043] Among them, the second input gear 541 is mounted on the power output shaft of the second stepping motor 52. The second input gear 541 meshes with the large gear of the double gear 542. The small gear of the double gear 542 meshes with the second gear portion 5431 of the second gear shaft 543. The second driving rotating shaft 53 is the second shaft portion of the second gear shaft 543.

[0044] During the process of the second stepping motor 52 driving the second driving rotating shaft 53 to rotate, the second input gear 541, the double gear 542, and the second gear portion 5431 of the second gear shaft 543 are meshed in sequence. The above reduction gear meshing structure can realize the high torque output of the second stepping motor 52 to ensure that the second stepping motor 52 can stably drive the lens mounting base 6 and the camera lens 3 to rotate in the horizontal direction.

[0045] The above content is only a preferred embodiment of the present invention. For those of ordinary skill in the art, based on the idea of the present invention, there will be changes in the specific implementation manner and application scope, and the content of this specification should not be construed as a limitation on the present invention.
