[0031] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0032] like Figure 1 As shown, a dimming mechanism of a double-module upper and lower arrangement of a headlight of an automobile provided by the utility model comprises an upper module 1 and a lower module 2 arranged in an upper and lower manner, and a rotating connecting rod 3 is connected between the upper module 1 and the lower module 2. A first fixed point 4 is provided on the lower module 2, a second fixed point 5 is provided on the rotating connecting rod 3, and a third fixed point 6 is provided on the upper module 1. The rotating connecting rod 3 rotates around the central axis of the second fixed point 5. The lower module 2 rotates around the first fixed point 4, and the connection point between the rotating connecting rod 3 and the lower module 2 is a first vertical adjustment point 7, and the lower module 2 is also provided with a first horizontal adjustment point 8. The upper module 1 rotates around the third fixed point 6, and the connection point between the rotating connecting rod 3 and the upper module 1 is a second vertical adjustment point 9, and the upper module 1 is also provided with a second horizontal adjustment point 10.

[0033] The technical solution of the present application adopts a rotating connecting rod 3 to respectively connect the brackets of the two lighting devices of the upper module 1 and the lower module 2, solving the technical problem that when multiple lighting units are arranged at a long distance up and down, the multiple lighting units cannot move downward at the same time and cannot adjust the light pattern at the same time to move downward together. In addition, the gap between the lighting unit and the surrounding parts is small, the weight is low, and it can meet the space requirements of the main engine manufacturer's automobile multiple lighting units arranged at a long distance up and down.

[0034] Specifically, the first fixed point 4, the second fixed point 5, the third fixed point 6, the first horizontal adjustment point 8, the second horizontal adjustment point 10, the first vertical adjustment point 7 and the second vertical adjustment point 9 are all ball head and ball socket matching. The upper die set 1 and the lower die set 2 are connected by a rotating connecting rod 3. The rotating connecting rod 3 is rotatably connected to the upper die set 1 and the lower die set 2 respectively through the ball head seat.

[0035] In a preferred embodiment of the present application, a motor is further included, and the motor drives the rotating connecting rod 3 to rotate around the axis of the second fixed point 5. The motor drives the rotating connecting rod 3 to rotate, and the upper die set 1 and the lower die set 2 both rotate downward by the same angle at the same time, or the upper die set 1 and the lower die set 2 both rotate upward by the same angle at the same time.

[0036] The output shaft of the motor is hinged to the side of the rotating link 3 close to the lower die set 2. The motor pushes the hinge point forward, and the lower die set 2 rotates downward around the central axis of the first fixed point 4. The rotating link 3 rotates in the opposite direction around the central axis of the second fixed point 5, driving the second vertical adjustment point 9 to move backward, and pulling the upper die set 1 to rotate downward clockwise around the central axis of the third fixed point 6. During the rotation process, the ball head of the rotating link 3 slides up and down in the Z-direction slot of the ball head seat. The same is true for the first vertical adjustment point 7 and the second vertical adjustment point 9.

[0037] It should be further explained that a more cost-effective solution is to cancel the ball head seat and use a slider to injection mold a cylindrical slide groove on the upper die set 1 and the lower die set 2. The rotating connecting rod 3 is directly connected to the upper die set 1 and the lower die set 2 respectively.

[0038] It should be further explained that the motor can be a DC motor or a stepper motor, and can be a manual-automatic motor or a non-manual-automatic motor. The spatial arrangement position of the motor includes the upper die set 1 , the lower die set 2 or the rotating connecting rod 3 .

[0039] In order to ensure that the upper module 1 and the lower module 2 of the two lighting units rotate downward or upward at the same angle synchronously, the dimming mechanism satisfies the following spatial relationship:

[0040] eb / 2ce≤bf / fa≤3eb / 2ce

[0041] Among them, eb represents the distance from the connection point of the upper mold group 1 and the rotating link 3 to the second fixed point 5, ce represents the distance from the connection point of the upper mold group 1 and the rotating link 3 to the third fixed point 6, bf represents the distance from the connection point of the lower mold group 2 and the rotating link 3 to the second fixed point 5, and fa represents the distance from the connection point of the lower mold group 2 and the rotating link 3 to the first fixed point 4.

[0042] Furthermore, eb may be equal to bf or not; the three points ebf do not necessarily need to be in a straight line, that is, ∠ebf is not necessarily equal to 180°.

[0043] like Figure 4 As shown, the adjustment triangle in this application is an inner triangle adjustment system, as shown in the left figure. It can also be an outer triangle adjustment system, as shown in the right figure.

[0044] In a preferred embodiment of the present application: the angle between the first horizontal adjustment point 8, the first fixed point 4 rotation, and the first vertical adjustment point 7 is 90 degrees. The angle between the second horizontal adjustment point 10, the third fixed point 6 rotation, and the second vertical adjustment point 9 is 90 degrees.

[0045] The utility model also provides a car, wherein the dimming mechanism is arranged at the head of the car body.
