[0002] As an important part of an automobile, vehicle lamps not only need to meet functional requirements but also safety requirements. At the same time, attention should be paid to showing brand aesthetics and improving user experience. The design concept of modern vehicle lamps has shifted from pursuing changes in shape and size to pursuing intelligence, energy conservation, environmental protection and personalization. The mechanical movement of the light-emitting element is an excellent way to achieve personalization. However, the mechanical movement of the light-emitting element on the market currently has problems of high cost and complex structure, which restricts the popularization and application of the light-emitting moving element.

[0003] In the existing structural design of vehicle lamps, if multiple movement directions need to be realized simultaneously, a large number of motors, gears, linkages, bearings, etc. are required, which leads to problems such as large structural tolerances, low reliability and high costs. Since OLED was introduced, due to the limitation of the light-emitting structure, it can only be made into a specific plane, and the high cost has led to its inability to be popularized. The brightness of OLED and optical fiber is too low, resulting in only an embellishment effect and occupying a large amount of space inside the lamp, which does not meet the requirements of simplicity and refinement of automotive industry parts.

[0046] Example 2:

[0047] Those skilled in the art can understand this embodiment as a more specific description of Embodiment 1.

[0048] This embodiment provides a headlight adjustment system. The optical component 1 and the optical component bracket 3 are assembled into an optical component sub-assembly through buckles and screws. The first bevel gear 4 and the second bevel gear 6 are installed together using the first support seat 5 and the second support seat 7 respectively. The first bevel gear 4 and the second bevel gear 6 can rotate freely around the first support seat 5 and the second support seat 7. The lead screw 9 is installed into the moving seat 8. The rack 10 is fixed on the lamp housing 13. The rack 11 and the bevel gear 26 are connected using the gear 10, and the lead screw 9 is connected to the motor 12. The optical component 1 is a grating.

[0049] Working principle:

[0050] The motor 12 drives the lead screw 9 to perform a rotational motion. The moving seat 8 can perform a telescopic motion as the lead screw 9 rotates. The first support seat 5 drives the optical component bracket 3 to perform a telescopic motion. At the same time, as the moving seat 8 telescopes, it drives the rotation of the gear 10. The rotation of the gear 10 on the rack 11 drives the rotation of the second bevel gear 6. Through the meshing of the first bevel gear 4 and the second bevel gear 6, it drives the grating to perform a rotational motion. In this way, light is emitted by the light source 2, the light source 2 irradiates on the grating, and the light is diffracted by different grooves or ridges on the grating to generate a series of diffracted light beams, achieving a 3D effect. The light source 2 is an LED.

[0051] Furthermore, the grating can be designed into any curved surface shape.

[0052] Furthermore, the first bevel gear 4 and the second bevel gear 6 can be replaced with gears or worm gears.

[0053] Furthermore, the motor 12 can be a stepper motor or a DC motor.

[0054] Furthermore, the lead screw 9 can be replaced with a screw or a sleeve mechanism.

[0055] Furthermore, by controlling the forward and reverse rotation directions of the motor 12, the grating can be rotated clockwise or counterclockwise.

[0056] Furthermore, by changing the position of the lead screw 9, the grating can move left and right and also perform a rotational motion.

[0057] Furthermore, the rack 11 can be replaced with a gear. The rack can be replaced with a rotatable gear. The rotatable gear is assembled on the support rod, and the motion is achieved through the meshing of two gears. The rotation of the gear 10 drives the rotatable gear, thereby achieving a telescopic motion. That is, the meshing of the gear and the rack is converted into the meshing of gear and gear.

[0058] Furthermore, the optical component sub-assembly can be designed as a signal light or an ambient light.

[0059] In this embodiment, by using the rotation and meshing of the lead screw and the gear, the problem of the power source for multiple moving directions of the moving parts inside the lamp is solved, and the synchronous rotation and telescoping of the moving parts are achieved under the drive of one power source.

[0060] In this embodiment, by using the cooperation of the lead screw and the gear, the problems of single moving direction and low power of the moving parts inside the lamp are solved, the personalized movement of the moving parts is realized, and the cost is low and the power is high.

[0061] In this embodiment, through the cooperation of the lead screw and the gear, the minimization of the space of the adjustment system and the optimization of the cost are achieved, so that the size and shape of the light-emitting surface are no longer restricted, and the light-emitting surface can be made into any curved surface shape to achieve the curved surface three-dimensional effect.

[0062] The shape of the conventional curved surface light-emitting part is fixed and has structural limitations, and it is impossible to use the same power source to simultaneously achieve the moving effects of rotation and telescoping in different directions. In this embodiment, one stepper motor can be used to simultaneously achieve the rotation and telescoping of the light-emitting surface.

[0063] The conventional moving structure inside the lamp is complex, and the number of transmission parts between the power source and the moving parts is large, resulting in low movement efficiency and movement lag. The structural design of this embodiment is concise and ingenious, greatly reducing the risk of movement lag.

[0064] The conventional moving structure inside the lamp occupies a large space, the number and size of parts are large, and the cost is high. The design of the light-emitting surface is restricted and can only be made into specific shapes, resulting in the inability to platformize and standardize the structural design. In this embodiment, through the cooperation of the lead screw and the gear, the occupied space and cost of the adjustment system are reduced, so that the light-emitting surface can be made into any curved surface shape to achieve the curved surface three-dimensional effect.

[0065] Through the linkage and cooperation of the lead screw and the gear, the present invention enables the light-emitting component to simultaneously achieve the functions of telescoping and rotation, and efficiently and with low cost realizes the 3D stereoscopic movable light-emitting effect.
