A new type of car light dimming screw and its manufacturing method

Abstract

The invention discloses a novel car lamp dimming screw and a manufacturing method thereof. The novel car lamp dimming screw is an integral column structure, and comprises a screw head, a screw rod and a thread, wherein the screw head is arranged on one end of the screw rod; the thread is arranged on the screw rod; the screw head is provided with an outer hexagon, and the lower surface of the screw head is provided with a gear; the screw rod is provided with a buckle which is connected with the screw rod to form an integral body; and the screw rod is provided with a concave annular groove which is provided with a seal gasket. The manufacturing method comprises the following steps: manufacturing a mold according to the structure of the manufactured novel car lamp dimming screw, carrying out one-step injection molding, and demolding to obtain the novel car lamp dimming screw. The novel car lamp dimming screw adopts the integral design, does not need splicing or component combination, can ensure the coaxial rotation of the whole screw in the car lamp dimming process, and ensures the balance adjustment of the car lamp. The screw head is provided with the outer hexagon, and the lower surface of the screw head is provided with the gear; and the novel car lamp dimming screw supports multiple car lamp adjustment modes, such as manual, electric and dynamic adjustment.

Description

technical field [0001] The invention relates to a novel dimming screw for vehicle lamps and a manufacturing method thereof, in particular to an integrated novel dimming screw for vehicle lamps with an outer 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 encou...

AI Technical Summary

Problems solved by technology

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