DETAILED DESCRIPTION

[0021] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0022] Please refer to Figures 1-6 The utility model provides a kind of speed change control cover assembly, including shell 1, it is made of ABS material, surface is black rough grain, thickness is 2.5mm, draft angle is 7 °;Shell 1 inner wall is provided with several buckle covers 4;

[0023] Dust cover 2, it is made of PU leather material, and is connected with shell 1 by buckle one 5;

[0024] The plug cover 3 is made of ABS material, is clamped by the buckle two 6 and forms a sealed fit with the shell 1.

[0025] In this embodiment, the variable speed control cover assembly is composed of the shell 1, the dust cover 2 and the plug cover 3. This combined structure design can form all-round protection for the automobile variable speed control components and ensure their stable operation in complex use environment. The shell 1 and the plug cover 3 are made of ABS material, which has good strength, corrosion resistance and forming processing performance, so that the shell and the plug cover 3 are not easy to deform and damage in the long-term use process, effectively prolonging the service life of the product. The dust cover 2 is made of PU leather material, which has the advantages of softness, wear resistance, waterproofness and dustproofness, can well play the role of the dust cover 2, and improve the texture of the product. The assembly adopts black coarse grain, which not only increases the aesthetic degree of the product, but also improves the touch. The thickness of the shell is 2.5 mm and the draft angle is 7°, which not only ensures the structural strength of the shell, but also facilitates the demolding operation in the production process, improving the production efficiency.
