Automobile headlamp optical lens support structure

Abstract

The invention discloses an automobile headlamp optical lens support structure. The automobile headlamp optical lens support structure comprises a left semicircular support, a right semicircular support and at least one lens clamped on the inner side of the left support and the inner side of the right support. The left support and the right support are oppositely closed to form a ring shape. Semicircular lens clamping grooves are formed in the inner side of the left support and the inner side of the right support, wherein the number of the semicircular lens clamping grooves is equal to the number of the lenses. Clamping rings are arranged on the edges of the lenses. Two arc metal clamping elastic pieces are oppositely arranged on the outer side of the oppositely-closed position of the left support and the right support and clamped in a hook groove in the left support and a hook groove in the right support through barbs at the two ends in a buckled manner. A left support fixing plate and a right support fixing plate are arranged at the rear end of the left support and the rear end of the right support. After the circle is formed through closing of the semicircular front lens clamping grooves and the semicircular rear lens clamping grooves, the circle is in interference fit with the clamping ring on the edge of the front lens and the clamping ring on the edge of the rear lens. According to the automobile headlamp optical lens support structure, the lenses are fixed more firmly, lens disengaging due to vibration or thermal expansion and cold contraction can be prevented, the lenses cannot fall out of the left support or the right support at all, and the overall support structure is more stable and safer.

Description

technical field [0001] The invention relates to spare parts of automobiles, in particular to an automobile headlight optical lens support structure. Background technique [0002] Existing car headlights are used to install the bracket of the optical lens, which is generally made into a whole ring, and a slot is arranged in the ring, and then the optical lens is forcibly snapped into the slot of the overall ring bracket. The lens can be fixed, but on the one hand, since the assembly is an integral snap-in assembly, when considering the problem of assembly fastening, the diameter of the integral ring bracket and the slot cannot be made too small, because too small will On the other hand, due to the overall snap-in assembly, rigid metal materials cannot be used to make the bracket ring, otherwise it will not fit in, so the only way to make the bracket ring is to use hard plastic materials, such as ABS plastic or PC plastic, and the plastic material itself expands with heat and...

Problems solved by technology

[0002] Existing car headlights are used to install the bracket of the optical lens, which is generally made into a whole ring, and a slot is arranged in the ring, and then the optical lens is forcibly snapped into the slot of the overall ring bracket. The lens can be fixed, but on the one hand, since the assembly is an integral snap-in assembly, when considering the problem of assembly fastening, the diameter of the integral ring bracket and the slot cannot be made too small, because too small will On the other hand, due to the overall snap-in assembly, rigid metal materials cannot be used to make the bracket ring, otherwise it will not fit in, so the only way to make the bracket ring is to use hard plastic materials, such as ABS plastic or PC plastic, and the plastic material itself expands with heat and contracts with cold, especially when the headlights of the car are turned on for a long time, a large amount of heat will be generated, which will be transferred to the bracket ring, causing the bracket ring to produce a thermal expansion effect, then, the bracket The inner diameter of the ring and the card slot will increase. At this time, under the premise that the diameter of the integral ring bracket and the card slot itself will not be made too small, the integral ring bracket and the card slot will clamp and fix the lens. It will be greatly reduced. If the road is bumpy and the car is bumped and vibrated, the lens will easily fall from the ring bracket, causing damage to the headlights and bringing danger to the car.
