[0003] The mechanism of automobile headlights is relatively complex, and the internal dimming structure is diverse. The layout of the dimming structure is affected by many factors such as the internal structure of the lamp and the body sheet metal, and cannot be arranged completely according to the direct dimming equipment, resulting in the inability to dim some dimming points. Direct dimming equipment can only arrange motors and other mechanisms in the normal direction of the dimming point, and cannot stagger the space, resulting in the sacrifice of a certain point for manual dimming by production line employees, which will result in higher dimming NG frequency, waste of time for re-inspection, and reduced production capacity of the production line. There are also manual adjustments to determine the light type point to the position where the lamp needs to be used. Manual adjustments have a slow adjustment speed, slow production cycle, high labor costs, and difficult operation. The problem of the lamp is becoming more and more obvious. Summary of the invention

[0020] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0021] like Figure 1 , 2As shown, this embodiment provides a non-directly connected automatic dimming device for a lamp, which includes a bottom mounting plate 1, a mounting bracket 2, a moving mechanism and a rotating adjustment mechanism, the mounting bracket 2 is fixed on the bottom mounting plate 1, the moving mechanism is fixed on the mounting bracket 2, the rotating adjustment mechanism is connected to the moving mechanism, and the moving mechanism is used to drive the rotating adjustment mechanism to move in the horizontal direction.

[0022] like Figure 1 As shown, the moving mechanism of this embodiment includes a cylinder 4, which is fixed on the mounting bracket 2. The piston rod of the cylinder 4 drives the rotary adjustment mechanism to move forward and backward in the horizontal direction.

[0023] like Figure 3 , 4 As shown in Figure 5, the rotation adjustment mechanism of this embodiment includes a mechanism fixing plate 31, a motor 32, a driving gear 33, a gear bracket 34, a driven gear 35, a first connecting rod 36, a second connecting rod 37 and a dimming rod 38. The mechanism fixing plate 31 is connected to the moving mechanism, the motor 32 is fixed on the mechanism fixing plate 31, the driving gear 33 is fixed on the motor 32 shaft of the motor 32, the gear bracket 34 is fixed on the mechanism fixing plate 31, one end of the first connecting rod 36 is rotatably connected to the gear bracket 34 through a bearing 341, the driven gear 35 is fixed to one end of the first connecting rod 36 and is located in the gear bracket 34, the driven gear 35 is meshed with the driving gear 33, one end of the second connecting rod 37 is slidably connected with the other end of the first connecting rod 36, and the dimming rod 38 is connected with the other end of the second connecting rod 37. The motor 32 rotates, and the driving gear 33 and the driven gear 35 are meshed and transmitted, and the driven gear 35 drives the first connecting rod 36 to rotate, and the first connecting rod 36 drives the dimming rod 38 to rotate through the second connecting rod 37. The dimming rod 38 is provided with a plug hole 381, and the moving mechanism drives the dimming rod 38 to enter the headlight dimming structure, and the plug hole 381 on the dimming rod 38 is plugged with the headlight dimming structure. Under the drive of the motor 32, the dimming rod 38 can rotate to perform a dimming operation on the headlight dimming structure. In this embodiment, the dimming column in the headlight dimming structure is hexagonal, and the shape of the plug hole 381 is correspondingly set to a plum blossom shape.

[0024] like Figure 3 , 4As shown in Figures 5 and 6, a slideway 361 for sliding one end of the second link 37 is provided in the other end of the first link 36 of this embodiment, a pin 371 is inserted into one end of the second link 37, and a slide groove 362 for sliding the pin 371 is provided on the side wall of the other end of the first link 36. A limit platform 372 is provided at the other end of the second link 37, and a spring 373 is provided between the limit platform 372 and the other end of the first link 36. In order to prevent the impact force generated by the dimming rod 38 under the propulsion of the cylinder 4 from damaging the headlamp dimming structure, the second link 37 and the first link 36 are provided with a sliding connection in this embodiment, and a spring 373 is added. When the dimming rod 38 contacts the headlamp dimming structure, the spring 373 is used for buffering, thereby reducing the impact of the dimming rod 38 on the headlamp dimming structure.

[0025] The working principle of the utility model is as follows:

[0026] During operation, the headlamp to be dimmed is placed on the tooling and fixed, and then the cylinder 4 pushes the entire rotary adjustment mechanism toward the headlamp, aligning the dimming rod 38 with the headlamp dimming structure. The adjustment rod and the motor 32 will cooperate closely with the headlamp dimming structure in the lamp through the buffering of the spring 373 under the push of the cylinder 4. The spring 373 can play a role of buffering and correction, and can protect the adjustment mechanism of the lamp itself from being damaged.

[0027] During the alignment process of the dimming rod 38 and the headlight dimming structure, the motor 32 will also rotate synchronously, so that the dimming rod 38 rotates simultaneously during the alignment process. Because before alignment, the headlight dimming structure may not be fully aligned with the mating hole 381 of the dimming rod 38, the dimming rod 38 needs to rotate synchronously during the alignment process so that the dimming rod 38 and the headlight dimming structure can be successfully mated. Then the kinetic energy of the motor 32 is transmitted to the first dimming link, the second dimming link, and the dimming rod 38 through the meshing of the active gear 33 and the passive gear 35. Due to the mating hole 381 at the head of the dimming rod 38 and the action of the spring 373, the dimming rod 38 and the headlight dimming structure will cooperate more closely, so that the dimming mechanism will function more stably during operation.

[0028] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
