Heat dissipation structure of automobile lamp

Abstract

The invention discloses a heat dissipation structure of an automobile lamp; the heat dissipation structure comprises a fin assembly and a connecting assembly; the fin assembly is formed by arranging aplurality of sheet-shaped fin base bodies in a surrounding mode, and the fin base bodies comprise a first base body and a second base body; the connecting assembly comprises a connecting block, the connecting block is provided with a clamping part, the upper end of the fin assembly is sleeved with the clamping part, the lower end of the inner side of the clamping part abuts against the upper endof a first body and is provided with a clamping head clamped into a clamping groove, the upper end of a second body sinks relative to the upper end of the first body so as to form a receding positionbetween the upper end of the second body and the lower end of the inner side of the clamping part, and a line outlet position in communication with the receding position is arranged outside the clamping part. A power line of the heat dissipation structure of the automobile lamp can penetrate through the receding position and then is led out from the line outlet position to the outside, greater convenience is brought to line outlet, the operation is simple, in addition, during installation, the connecting assembly is connected into the clamping groove of the fin assembly in a clamped mode through the clamping head, so that rapid installation of the heat dissipation structure of the automobile lamp is achieved, operation of bolt driving is not needed, and production efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of automobile lamps, in particular to a heat dissipation structure for automobile lamps. Background technique [0002] LEDs are widely used in automotive lights because of their small size, energy saving, and long life. However, LED car lights will generate a lot of heat during use, so LED car lights are usually equipped with heat dissipation structures. In the current heat dissipation structure of automobile lamps, many of them use fin radiators and fans for heat dissipation. When installing, a mounting plate is welded at the end of the fin radiator. There are threaded holes on the mounting plate, and then the fan is connected to the lamp by bolts. On the mounting board, since the size of the fin radiator of the car light is usually relatively small, the above-mentioned installation operation is very inconvenient and the efficiency is relatively low; and the power lines of the LED and the fan are drawn out...

Problems solved by technology

In the current heat dissipation structure of automobile lamps, many of them use fin radiators and fans for heat dissipation. When installing, a mounting plate is welded at the end of the fin radiator. There are threaded holes on the mounting plate, and then the fan is connected to the lamp by bolts. On the mounting board, since the size of the fin radiator of the car light is usually relatively small, the above-mentioned installation operation is very inconvenient and the efficiency is relatively low; and the power lines of the LED and the fan are drawn out through the opening of the fin radiator. There is usually a fan installed on the opening, so the outlet is very inconvenient and the operation is difficult
