Specific embodiments

[0023] The present utility model will be described below in conjunction with specific embodiments.

[0024] Embodiment 1, as Figures 1 to 3 shown, a new type of two-dimensional linkage mirror frame assembly includes a first driving motor 1, a lens holder 2, and a lens 3. The lens 3 is installed on the lens holder 2, and the power output shaft of the first driving motor 1 is connected to the lens holder 2.

[0025] Further, as Figures 1 to 4 shown, the new type of two-dimensional linkage mirror frame assembly further includes a movable rotating frame 4 and a second driving motor 5. The first driving motor 1 is fixedly installed on the movable rotating frame 4; the second driving motor 5 is a stepper reduction motor composed of a stepper motor 51 and a reduction gearbox 52. The power output shaft of the second driving motor 5 is connected to the movable rotating frame 4; during operation, the second driving motor 5 drives the movable rotating frame 4 to perform a vertical rotation action, and the first driving motor 1 drives the lens holder 2 to perform a horizontal rotation action.

[0026] Furthermore, as Figures 1 to 3 shown, the lens holder 2 is arranged obliquely, and a position-limiting convex block 21 extending downward and obliquely is provided at the edge of the lens holder 2. The movable rotating frame 4 is provided with a first position stop wall 41 and a second position stop wall 42 arranged at intervals corresponding to the position-limiting convex block 21; when the lens holder 2 rotates relative to the movable rotating frame 4 to the first position, the position-limiting convex block 21 abuts and is limited by the first position stop wall 41; when the lens holder 2 rotates relative to the movable rotating frame 4 to the second position, the position-limiting convex block 21 abuts and is limited by the second position stop wall 42.

[0027] It should be noted that the second driving motor 5 of the first embodiment can be fixedly installed on the corresponding fixed support. During the operation of the new two-dimensional linkage mirror frame assembly of the first embodiment, the second driving motor 5 drives the movable rotating frame 4 to rotate vertically. The movable rotating frame 4 that rotates vertically drives the first driving motor 1, the lens holder 2, and the lens 3 to rotate vertically synchronously, thereby realizing the vertical rotation of the lens 3 to adjust the position. The first driving motor 1 drives the lens holder 2 to rotate horizontally. The lens holder 2 that rotates horizontally drives the lens 3 to rotate horizontally synchronously, thereby realizing the horizontal rotation of the lens 3 to adjust the position. Therefore, the new two-dimensional linkage mirror frame assembly of the first embodiment can effectively realize the two-dimensional rotation of the lens 3, and adjust the position of the lens 3 through the rotation in two dimensions, that is, the position control of the lens 3 can be made more accurate.

[0028] In addition, during the process of the first driving motor 1 driving the lens 3 to rotate horizontally to adjust the horizontal position, when the lens holder 2 rotates relative to the movable rotating frame 4 to the first position, the stop projection 21 abuts and is limited by the first position stop wall 41. When the lens holder 2 rotates relative to the movable rotating frame 4 to the second position, the stop projection 21 abuts and is limited by the second position stop wall 42. By the cooperation of the stop projection 21 with the first position stop wall 41 and the second position stop wall 42, the first embodiment can accurately control the limit position of the lens holder 2.

[0029] In addition, the second driving motor 5 of the first embodiment is composed of a stepping motor 51 and a reduction gearbox 52. The structure of the second driving motor 5 can output a large torque, and thus can effectively ensure that the second driving motor 5 can effectively drive the movable rotating frame 4, the first driving motor 1, the lens holder 2, and the lens 3 to rotate vertically.

[0030] Based on the above situation, through the above structural design, the new two-dimensional linkage mirror frame assembly of the first embodiment has the advantages of novel structural design, can realize the two-dimensional rotation of the lens 3, and makes the position control of the lens 3 more accurate.

[0032] It should be noted that, as Figures 1 to 3As shown, an elastic retaining ring is also sleeved on the end of the output shaft anti-rotation portion 53 to achieve axial limit between the rotating frame driving portion 43 and the output shaft anti-rotation portion 53 through the elastic retaining ring.

[0033] Embodiment 3, as Figures 1 to 4 shown, the difference between this Embodiment 3 and Embodiment 1 is that the first driving motor 1 of this Embodiment 3 can be installed and fastened to the movable rotating frame 4 in the following manner. Specifically: the movable rotating frame 4 is provided with a motor accommodating cavity 44 with an upward opening, the first driving motor 1 is embedded into the motor accommodating cavity 44 of the movable rotating frame 4, and the first driving motor 1 is screwed and fastened to the movable rotating frame 4 through locking screws.
