[0063] Based on this, the embodiment of this specification proposes a lens adjustment device, including:

[0064] like Figure 1 As shown, the lens adjustment device includes a lens 500, a lens seat 400, a lens barrel 200, a horizontal adjustment mechanism and a vertical adjustment mechanism. The center of the lens seat 400 is hollowed out, and the lens 500 is fixed in the center of the lens seat 400. The movement of the lens seat 400 drives the movement of the lens 500. The lens seat 400 is fixedly connected to the lens barrel 200, and the lens barrel 200 is respectively provided with a horizontal adjustment mechanism and a vertical adjustment mechanism.

[0065] like Figure 2 As shown, a first cutting groove 441 and a second cutting groove 442 that do not intersect are formed on the mirror base 400, and there is an overlapping portion between the first cutting groove 441 and the second cutting groove 442, and a leaf spring structure is formed in the overlapping portion. A third cutting groove 443 and a fourth cutting groove 444 that do not intersect are also formed on the mirror base 400, and there is an overlapping portion between the third cutting groove 443 and the fourth cutting groove 444, and a leaf spring structure is formed in the overlapping portion.

[0066] Preferably, the horizontal adjustment mechanism drives the leaf spring structure formed between the first cutting groove 441 and the second cutting groove 442 to drive the mirror base 400 to move along the second direction, and the horizontal adjustment mechanism drives the leaf spring structure formed between the third cutting groove 443 and the fourth cutting groove 444 to drive the mirror base 400 to move along the first direction, and the vertical adjustment mechanism is used to drive the mirror base 400 to move along the third direction.

[0067] Preferably, the first cutting groove 441 , the second cutting groove 442 , the third cutting groove 443 , and the fourth cutting groove 444 are U-shaped grooves and through grooves to form a leaf spring structure.

[0068] Preferably, a first leaf spring structure 450A and a second leaf spring structure 450B are formed between the first cutting groove 441 and the second cutting groove 442, and the first leaf spring structure 450A is symmetrical and parallel to the second leaf spring structure 450B in the first direction. A third leaf spring structure 460A and a fourth leaf spring structure 460B are formed between the third cutting groove 443 and the fourth cutting groove 444, and the third leaf spring structure 460A is symmetrical and parallel to the fourth leaf spring structure 460B in the second direction. The leaf spring structure has a certain toughness and can withstand driving forces in multiple directions to achieve fine-tuning of the tilt angle of the lens 500.

[0069] Preferably, the first cutting groove 441, the second cutting groove 442, the third cutting groove 443 and the fourth cutting groove 444 divide the lens holder 400 into three parts, namely the outer ring 400a, the middle ring 400b and the inner ring 400c. The inner ring 400c and the middle ring 400b are connected by the first leaf spring structure 450A and the second leaf spring structure 450B, the outer ring 400a and the middle ring 400b are connected by the third leaf spring structure 460A and the fourth leaf spring structure 460B, the outer ring 400a is connected to the centering spring leaf 300, and the inner ring 400c, the middle ring 400b and the outer ring 400a are connected by leaf springs to drive the lens 500 to move in different directions.

[0070] Preferably, the horizontal adjustment mechanism includes a first horizontal adjustment mechanism and a second horizontal adjustment mechanism. The first horizontal adjustment mechanism includes a first motor 100-2 and a first push rod 623. In the first horizontal adjustment mechanism, one end of the first push rod 623 is connected to the first motor 100-2, and the other end contacts the leaf spring structure formed between the third cutting groove 443 and the fourth cutting groove 444 under the drive of the first motor 100-2, so that the mirror seat 400 moves along the first direction.

[0071] Preferably, a pressure hole is provided on the side wall of the lens holder 400, and the first push rod 623 passes through the pressure hole and is set on one side of the middle part of the first leaf spring structure 450A. The first motor 100-2 drives the first push rod 62 to press the first leaf spring structure 450A, driving the lens to deform and move in the direction of the second leaf spring structure 450B.

[0072] Specifically, Figure 6a , 6b As shown in Figures 6c, a through hole is provided in the middle of the first leaf spring structure 450A and the second leaf spring structure 450B. The driving motor 100-2 drives the second push rod 613 to pass through the through hole and press against the inner wall of the U-shaped cutting groove at the first leaf spring structure 450A. At this time, the second leaf spring structure 450B on the opposite side will be subjected to pressure. The leaf spring structure can withstand a certain pressure deformation, so that the middle circle 400b can be pushed a certain distance by the second push rod 613 to realize the movement of the middle circle 400b in the -X direction.

[0073] Preferably, the horizontal adjustment mechanism and the vertical adjustment mechanism also include an elastic component, which may be a spring. Taking the first horizontal adjustment mechanism as an example, a spring 622 is sleeved on each first pressure rod 621 to ensure that the spring will not shift when subjected to force. The spring 622 and the first pressure rod 621 are arranged between the lens barrel 200 and the fourth leaf spring structure 460B, and are arranged on the same straight line as the first push rod 623, that is, the spring 622 is arranged on the opposite side of the first push rod 623, and the preload force provided by the spring 622 is used to realize the movement of the middle circle 400b along the +X direction. The preload force of the spring 622 is adjusted by the first pressure rod 621.

[0074] like Figure 7c As shown, the second horizontal adjustment mechanism includes a second motor 100-3 and a second push rod 613. In the second horizontal adjustment mechanism, one end of the second push rod 613 is connected to the second motor 100-3, and the other end contacts the leaf spring structure formed between the first cutting groove 441 and the second cutting groove 442 under the drive of the second motor 100-3, so that the mirror seat 400 moves along the second direction.

[0075] like Figure 7b As shown, similar to the first horizontal driving mechanism in the X direction, the second motor 100-3 of the second horizontal driving mechanism drives the second push rod 613 to pass through the through hole and press against the inner wall of the U-shaped cutting groove at the second leaf spring structure 450B. The motor 100-3 drives the inner ring 400c of the mirror seat 400 to move in the +Y direction. The preload force provided by the spring 612 causes the inner ring 400c to move in the -Y direction. The preload force of the spring 622 is adjusted by the second pressure rod 611.

[0076] Since the middle circle 400b is connected to the inner circle 400c, the middle circle 400b can drive the inner circle 400c to move in the X direction, and thus the lens can move in the X direction.

[0077] The horizontal adjustment mechanism in the X and Y directions can realize the movement of the lens 500 in the X and Y directions, and the movement decoupling is good, and the movement of the X and Y axes will not cause crosstalk.

[0078] Preferably, the driving motors are fixedly mounted on the outer wall of the lens barrel 200 .

[0079] like Figure 3 and Figure 4 As shown, the lens adjustment device also includes two layers of centering springs 300, which are respectively arranged on the first side and the second side of the lens base 400. The centering springs 300 form a parallelogram structure, so that the lens base 400 can only move in the Z direction.

[0080] Preferably, the first end of the centering spring 300 is fixed to the lens holder 400 via an inner pressure ring 310 , and the second end of the centering spring 300 is fixed to the lens barrel 200 via an outer pressure ring 320 .

[0081] like Figure 5 As shown, a centering spring 300 is installed on each of the upper and lower end surfaces of the lens holder 400, the centering spring 300 is fixed to the lens holder 400 by an inner pressure ring 310, and the centering spring 300 is fixed to the lens barrel 200 by an outer pressure ring 320. The centering springs 300 of the upper and lower layers form a parallelogram structure, ensuring that the lens holder 400 can only move in the Z direction, and the degrees of freedom of movement in the other five directions are all restricted. The lens holder 400 is driven by the vertical adjustment mechanism to realize the movement of the lens 500 in the Z direction.

[0082] like Figure 8a , 8b As shown, the vertical adjustment mechanism includes a third motor 100-1, a third top rod 636, a rotating member 635, a flexible bearing 634, a support frame 633, a first fixed seat 631 and a second fixed seat 638, the first fixed seat 631 is fixed on the first side of the mirror base 400, and the second fixed seat 638 is fixed on the second side of the mirror base 400.

[0083] like Fig. 9 As shown, a first through hole 639 and a groove 640 are provided on the rotating member 635, the flexible bearing 634 passes through the first through hole 639 and the two ends of the flexible bearing 634 are respectively fixed on the support frame 633, one end of the third push rod 636 is connected to the third motor 100-1, and the other end is in contact with the rotating member 635, the rotating member 635 can rotate around the flexible bearing 634, a steel ball is provided inside the groove 640, the rotating member 635 is connected to the first fixed seat 631 via the steel ball, and the rotating member 635 is an inverted L-shape.

[0084] Driven by the third motor 100 - 1 , the third push rod 636 pushes the lower end of the rotating rod, converting the movement of the third push rod 636 along the first direction into the movement along the third direction, so that the lens can move in the Z direction.

[0085] like Fig.11As shown, the flexible bearing 634 includes a first part 634a, a second part 634b and a third part 634c. The first part 634a and the third part 634c are fixed to the support frame 633 by gluing, and the second part 634b is fixed to the rotating member 635 by gluing.

[0086] Preferably, each push rod is sleeved with a sealing ring to achieve sealing inside the lens barrel 200 to prevent affecting the imaging quality.
