Description
Technical Field
[0001] The utility model relates to the technical field of vehicle lamps, and particularly to a multifunctional linkage adjustment device inside a lamp. Background Technique
[0002] At present, the basic applications of vehicle lamps in the automotive market have been very mature. In order to pursue the differences and uniqueness of shapes and functions, customers require that the internal components of the lamps have movable functions. Since the automotive development has relatively high requirements for the weight and power of vehicle lamps, and the automotive regulations for the standards of components are much higher than those of civilian and other industrial products, the currently available power sources for moving parts inside vehicle lamps are only motors.
[0003] In the prior art structural design solutions, if multiple functions require movement, then multiple power sources are needed. Multiple power sources cannot meet the automotive development requirements due to high costs, poor matching relationships, and electronic interference between each other, which increases the risk of lamp failure. In addition, too many power sources occupy driving resources, and platform driving cannot meet the needs of multiple power sources. Defining drives for multiple power sources does not meet the requirements of component platformization in the industrialization process.
[0004] The traditional moving parts inside the lamp have the following problems: a. Since the torque of the power source of the traditional moving parts is small, such as using a rotary motor, only small parts such as decorative parts and ambient lights can be moved. In this application, an axial movement large-torque stepper motor is used, which can realize the movement of the module assembly, the thick-wall part assembly, and even the lamp assembly. Subsequently, a hydraulic device can be used to replace the stepper motor as the movement source; b. If there are two or more moving parts inside the traditional lamp, since there is no mechanical movement connection between the two or more moving parts, there is a possibility of collision and interference between the moving parts. In this application, a connecting rod is used for joint adjustment, and mechanical means are used to ensure synchronous movement between the two moving parts, and there is no possibility of collision.
