[0002] Plastic accessories refer to various accessories or parts made of plastic materials through various molding processes (such as injection molding, blow molding, extrusion molding, etc.). These accessories are widely used in industries such as automobiles, electronics, home appliances, toys, medical equipment, and packaging. Plastic accessories have many advantages, including light weight, low cost, easy molding, corrosion resistance and good insulation. Therefore, they play a vital role in modern industry and daily life.
[0003] Application No. 202223095113.3 discloses a precision weather-resistant automotive plastic accessory. "Both sides of the core are provided with adhesive layers, and the core is fixedly connected to the first connecting member and the second connecting member through the adhesive layers. The outer side of the plastic part body and the outer sides of the first connecting member and the second connecting member are provided with a PET wear-resistant coating, and the outer side of the PET wear-resistant coating is provided with a polyamide anti-oxidation coating; the PET wear-resistant coating and the polyamide anti-oxidation coating can protect the core, the first connecting member and the second connecting member." In the above, a single adhesive layer may age over time, especially under long-term exposure to ultraviolet rays. UV radiation will cause certain adhesive materials to undergo photochemical reactions, thereby reducing their bonding properties. In an environment of high temperature or chemical substances, high temperature will accelerate the thermal degradation process of the adhesive, causing the adhesive layer to soften, flow or even decompose, reducing the bonding strength, and thus affecting the connectivity between devices.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] See also Figures 1-4 As shown, the utility model provides the following technical solutions: a precision weather-resistant automotive plastic accessory, comprising: a plastic body 1, the plastic body 1 being provided with a plastic outer wall 2 and a plastic inner wall 3, a first connecting member 4 and a second connecting member 5 being respectively installed at the upper and lower ends of the plastic body 1, an adhesive layer 6 being provided between the first connecting member 4 and the plastic body 1 and between the second connecting member 5 and the plastic body 1, a plurality of mounting grooves 7 being opened on the plastic body 1, a plurality of mounting blocks 8 being connected to the first connecting member 4 and the second connecting member 5, and a snap-on assembly being provided between each mounting block 8 and the mounting groove 7.
[0021] Furthermore, the card connection assembly includes a card slot 9, a connecting block 10, a hollow block 11 and a spring 12. The card slot 9 is opened on the side wall of the mounting slot 7, the connecting block 10 is fixed on the outer wall of the mounting block 8, a hollow block 11 is provided on one side of the connecting block 10, and a part of the connecting block 10 is located in the hollow block 11. A spring 12 is installed between the connecting block 10 and the hollow block 11, and the hollow block 11 is adapted to the card slot 9.
[0022] Furthermore, the plastic body 1 , the first connecting member 4 and the second connecting member 5 are all annular structures.
[0023] Through the above technical solution:
[0024] During use, apply adhesive layer 6 on the upper and lower ends of the plastic body 1, align the mounting block 8 and the mounting groove 7, press the first connecting member 4 and the second connecting member 5 toward the side close to the plastic body 1, and the mounting block 8 drives the connecting block 10 and the hollow block 11 to move in the mounting groove 7 until the spring 12 pushes the hollow block 11 into the card slot 9, thereby achieving the limitation between the first connecting member 4 and the plastic body 1 and between the second connecting member 5 and the plastic body 1. The card connection method provides mechanical locking and can withstand greater tension and pressure. Compared with a single bonding, its connection strength and reliability are higher. Moreover, because the mechanical locking allows a certain amount of movement space between the components, the overall equipment can better adapt to the thermal expansion and contraction of the material, ensuring that the accessories have better durability in harsh environments.
[0025] See also Figure 1 and Figure 3 As shown, a wear-resistant coating 13 is provided on one side of the outer wall 2 of the plastic part, and an anti-ultraviolet coating 14 is provided on one side of the wear-resistant coating 13 .
[0026] Furthermore, a thermal management coating 15 is provided on one side of the inner wall 3 of the plastic component, and a chemical resistance coating 16 is provided on one side of the thermal management coating 15 .
[0027] Through the above technical solution:
[0028] During use, the wear-resistant coating 13 may be a composite coating of polyurethane (PU), acrylic resin, and ceramic particles, thereby improving the wear resistance of the surface of the plastic body 1 and reducing wear. The UV-resistant coating 14, containing a coating containing a UV absorber or stabilizer, such as UV-stabilized acrylic or polyurethane, can protect the surface of the plastic body 1 from UV damage, thereby extending the service life. The thermal management coating 15 uses materials with high thermal conductivity, such as graphene and carbon nanotubes, to improve the thermal conductivity of the components of the plastic body 1. The chemical-resistant coating 16 may be made of fluorocarbon resin, epoxy resin, and polytetrafluoroethylene (PTFE), thereby resisting the corrosion of chemical substances such as oil, solvents, acids, and alkalis. By providing the wear-resistant coating 13, UV-resistant coating 14, thermal management coating 15, and chemical-resistant coating 16, the plastic body 1 can be better adapted to various harsh working environments, improving the performance and reliability of the plastic body 1 and extending its service life. This not only helps reduce maintenance costs and replacement frequency, but also enhances the overall value of the product and user satisfaction.
[0029] For further information, see Figure 1 As shown, a plurality of reinforcing ribs 17 are installed in the plastic body 1 , and the plurality of reinforcing ribs 17 are all in contact with the inner wall 3 of the plastic.
[0030] Specifically, the reinforcing ribs 17 can significantly improve the bending, torsional and compressive strength of the plastic body 1, making it less likely to deform or break when subjected to external forces. Without sacrificing strength and rigidity, the use of the reinforcing ribs 17 structure can reduce the amount of plastic material used, thereby achieving the purpose of reducing the weight of the plastic body 1.
[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
