Background

With the increasingly competitive automobile industry, the profit of the automobile industry is continuously reduced, and the research and development of new processes and all new technologies capable of reducing the production cost become an important task for automobile enterprises.

A finished automobile generally adopts buckles to fixedly mount parts such as headlights and the like. However, the mounting nuts in the prior art are mostly metal, which has the following disadvantages: one is as follows: the metal mounting nut is expensive to manufacture. The reason is that (1) in order to improve the properties of the metal mounting nut such as elasticity, hardness, strength and the like, the metal mounting nut needs to be subjected to manufacturing processes such as heat treatment, surface treatment, martensite annealing treatment and the like, and the process is complex and complicated; (2) in order to prevent the metal mounting nut from rusting, the metal mounting nut needs to be subjected to surface treatment, and the salt spray experiment is guaranteed to have no red embroidery within 48 hours. The second step is as follows: the metal has high density, so that the weight of the metal mounting nut is high, and the transportation cost is increased. And thirdly: the metal mounting nut is large in hardness, most of automobile parts are made of plastic materials, and the hardness is small, so that the metal mounting nut is difficult to pull out once being mounted, and when the parts are maintained or need to be detached, the operation of pulling out the metal mounting nut can easily cause other parts to break, so that a matched product is damaged. Fourthly, the method comprises the following steps: the metal mounting nut needs heat treatment and surface treatment in the manufacturing process, and the environment is polluted.

In order to overcome the above-mentioned defect, chinese utility model patent with patent number 201820353649.5 discloses a plastics is fixed to be detained for car, and it includes: the body, the body top is equipped with the latch, the side bottom is equipped with the buckle respectively about the latch, the buckle is equipped with the buckle groove, buckle groove swing joint activity buckle, the main part is equipped with shrink groove and shrink groove down, go up shrink groove with shrink groove both ends are the flexible knot of swing joint respectively about down, the main part bottom still is equipped with thick separation blade. The utility model has the advantages that: the movable buckle can freely change the distance of moving up and down by adopting the design of the buckle groove and the movable buckle; the design of the telescopic groove and the telescopic buckle is adopted, the size of the bayonet of the telescopic buckle is changed, and different requirements are met; simple structure is convenient for install.

The Chinese patent application with the patent number of 201811351754.6 discloses a buckle type automobile instrument structure and an installation method thereof, the buckle type automobile instrument structure comprises an instrument body, a plurality of clamping pins are arranged on the lower surface of the instrument body, the top ends of the clamping pins are hinged to the lower surface of the instrument body through pin shafts, the inner side surfaces of the clamping pins are rotatably connected to the bottom end of a first push rod through ear plates fixed in a welding mode, the top end of the first push rod is connected to the bottom of the instrument body through another ear plate, the bottom ends of the clamping pins are inserted into jacks in a center console and are clamped in the center console, and a connecting sleeve is rotatably connected to the periphery of the bottom of the instrument body. According to the invention, the connecting sleeve is rotated, the ejector block on the connecting sleeve interacts with the limiting block on the clamping pin to push the clamping pin to contract inwards, so that the clamping pin is loosened from the jack on the central console, the instrument body can be automatically ejected out during disassembly through the backing plate, the instrument is disassembled from the outside, and the instrument is convenient to install and maintain and firm to install.

However, the mounting nut in the patent technology is complex in structure, and the manufacturing difficulty and the mounting difficulty of the mounting nut are increased; and when the parts need to be fixedly installed at the edge position of the automobile, the edge position of the automobile is more easily damaged due to the installation of the parts.
