Abstract

The invention provides a fastening structure of a vehicle lamp. The fastening structure comprises a shell for supporting and installing the vehicle lamp, a light-emitting unit providing a light source for the vehicle lamp, a light distributing unit facing the light-emitting unit and distributing light emitted by the light source in a preset mode, a printed circuit board for driving and controlling the light-emitting unit, a lining frame unit used for supporting and installing the light distributing unit and connected to the shell and at least one retaining unit for containing and bearing the printed circuit board and locating the printed circuit board inside the shell. According to the fastening structure of the vehicle lamp, the printed circuit board is stable and reliable, the design is simple and compact, additional locating elements are not needed, and therefore the processing cost is lowered, and the convenience of the assembly technology is improved.

Description

technical field [0001] The invention relates to the field of vehicle spare parts, in particular to a fastening and limiting structure applied to a control circuit board of a front lighting device. Background technique [0002] As vehicles gradually enter the family, users have higher and higher requirements for the components of the vehicle, and corresponding requirements are also put forward for the structure of the car lights. For the PCB printed circuit board that provides the driving and control of the light source of the car lamp, it must be electrically connected to the light source module, and a supporting mechanism is also required to provide its installation and positioning. In the prior art, the PCB printed circuit board is inserted into the corresponding slot provided in the car lamp housing, however, such a structure may cause the PCB printed circuit board to fall off the slot during the vibration process, which in turn causes damage to the light source module. ...
