Description

Technical Field

[0001] The present invention relates to the technical field of headlamps, and more particularly to a self-locking headlamp. Background Art

[0002] Headlamps, as crucial lighting devices at the front of a vehicle, not only provide drivers with sufficient illumination to clearly identify road conditions and obstacles at night or in low-light conditions, but also serve as signals, such as by switching between high and low beams to communicate with other road users. Their design must balance lighting efficiency, illumination range, energy consumption, and compliance with traffic safety standards. Headlamps are not only a fundamental component of a vehicle, but their technological advancements and innovations are crucial for improving road safety and enhancing the driving experience.

[0003] As shown in the prior art publication No. CN103244890A, although the aluminum-plated reflector in this prior art has a higher reflection efficiency, reaching 70-80%, this prior art, however, only uses multiple screws to fix the headlamp when assembling it. This results in a relatively simple fastening method and only one self-locking screw method. When the screws become loose, this technical solution cannot ensure stability through other structures.

[0004] Furthermore, when the components in this technical solution are in operation, the heat therein cannot be effectively dissipated but instead accumulates, and the accumulation of heat affects the performance of the components. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a self-locking headlamp, which can perform multiple self-locking fixations on the headlamp body through the engagement of the elastic lock buckle with the buckle, the engagement of the fixing buckle with the fixing buckle, and the rotational engagement of the limiting slider with the limiting groove, thereby ensuring the stability and connection tightness of the headlamp body, and finally tightening it with the help of expansion pins. The assembly is simple, and multiple self-locking fixations can be achieved with high firmness, which can effectively ensure the performance of the headlamp body, thereby solving the problems arising from the above-mentioned background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a self-locking headlamp, comprising a headlamp body that is convenient to disassemble and assemble;
