Dimming screw for vehicle lamp and manufacturing method thereof

Abstract

The invention discloses a car lamp light adjusting screw and a manufacturing method thereof. The car lamp light adjusting screw is of an integrated columnar structure and comprises a screw head, a screw rod and a thread. The screw head is arranged at one end of the screw rod. The thread is arranged on the screw rod. An inner cross and an inner hexagon are formed in the screw head. Gears are arranged on an outer circle of the screw head. A buckle is arranged on the screw rod and connected with the screw rod into a whole. A concave ring groove for mounting a sealing washer is formed in the screw rod. A limiting ring is arranged on the screw rod. According to the manufacturing method of the car lamp light adjusting screw, a mold is manufactured according to the structure of the car lamp light adjusting screw to be manufactured, the one-time injection molding method is adopted, and the car lamp light adjusting screw is manufactured through demolding. The car lamp light adjusting screw adopts the integrated design and is free of splicing and assembling components, the effect that the whole screw rotates coaxially during car lamp light adjusting can be ensured, and the car lamp light balance adjustment is ensured; and meanwhile, the inner cross and the inner hexagon are formed in the screw head, the gears are arranged on the outer circle of the screw head, and various car lamp adjustment modes, namely a manual mode, an electric mode and a dynamic mode can be achieved.

Description

technical field [0001] The present invention relates to a vehicle light dimming screw and a manufacturing method thereof, in particular to an integrated vehicle light dimming screw with an inner cross, an inner hexagon and a gear and a manufacturing method thereof. Background technique [0002] As we all know, when the load of the car changes, it will cause the change of the inclination angle of the car body relative to the road surface, which will lead to the change of the lighting distance and lighting direction of the car lights. When the car adds an extra load or accelerates sharply, the rear of the car will drop and the front will rise (the level of the front and rear of the car changes), which will dazzle oncoming drivers and cause lighting on the road surface Insufficient; when the car brakes suddenly, the front part will drop and the tail will rise, and the direct sight distance will be greatly shortened at this time. When the car is driving at night, it will also e...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the fact that the car lamp dimming screw is composed of multiple parts, it is difficult to achieve the same axis rotation of a single product, and the coaxial rotation of the product and the balance of the car lamp cannot be guaranteed, and the internal cross and internal hexagon cannot be performed at the same time. In order to solve the problem of dimming in various ways such as gears and gears, the present invention provides an integrated car lamp dimming screw with inner cross, inner hexagon and gears and its manufacturing method
