[0020] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the utility model will be further described in detail below by combining with the drawings and specific embodiments.

[0021] A glass nail column for automobile glass, referring to Figures 1-2 , comprising a seat body 10, a column body 20 and an outer cover 30, the bottom surface of the seat body 10 is used for connecting to glass, the column body 20 is fixed to the top surface of the seat body 10, the outer cover 30 is sleeved on the column body 20, and the inner side wall of the outer cover 30 is tightly attached to the outer side wall of the column body 20, the material of the outer cover 30 is polyoxymethylene (POM), so that the outer side wall becomes a self-lubricating wear-resistant surface.

[0022] The glass nail column in the embodiment has the outer cover 30 arranged outside the existing glass nail column, the outer cover 30 is sleeved on the column body 20, and the inner side wall of the outer cover 30 is close to the outer side wall of the column body 20, so that the assembly effect of the outer cover 30 and the column body 20 and the connection reliability of the two can be ensured. The material of the outer cover 30 is polyformaldehyde, so that the outer side wall of the outer cover 30 is a self-lubricating wear-resistant surface. The self-lubricating wear-resistant surface has high strength and good wear resistance, can meet the use requirements of the glass nail column, and can also improve the service life of the column body 20, thereby improving the service life of the glass nail column. The self-lubricating wear-resistant surface also has the characteristics of low friction coefficient, so that the glass nail column has a lubricating effect, and the column body 20 is more convenient to be inserted into the body panel rib during assembly, and the assembly is convenient. At the same time, under the action of the first friction coefficient and self-lubrication during use, the friction noise between the column body 20 and the body panel rib is reduced, and the use experience is improved.

[0023] In the embodiment, the outer cover 30 is an integrally formed structure formed by an injection molding process. After the integrally formed outer cover 30 is directly sleeved on the column body 20, the assembly of the outer cover 30 can be realized, and the operation is simple.

[0024] In order to ensure the assembly effect, the outer cover 30 and the column body 20 are in interference fit, and further, the two can be further fixed by a colloid.

[0025] In other optional embodiments, the outer side wall of the column body 20 is wrapped with a polyformaldehyde adhesive tape to form the outer cover 30. In this embodiment, although the process of forming the outer cover 30 and the assembly process of the outer cover 30 are relatively troublesome, the development of the grinding tool and the manufacturing cost are saved, the cost is lower, and the fixing effect of the outer cover 30 and the column body 20 can be ensured.

[0026] In the embodiment, the free end of the column body 20 is the butt joint end 21, the radial dimension of the outer side wall of the butt joint end 21 gradually decreases away from the base to form the guide surface 22, which facilitates the connection of the column body 20 and the body panel rib.

[0027] In order to ensure the wear resistance and lubricating effect of the outer side wall of the column body 20, the bottom of the outer cover 30 is located at the root of the column body 20, and the top of the outer cover 30 is located in the butt joint end 21. Since the radial dimension of the guide surface 22 gradually decreases away from the base, the contact between the guide surface 22 and the body panel rib is not frequent, so the top of the outer cover 30 is located in the butt joint end 21, but does not cover the entire butt joint end 21. This reduces the size of the outer cover 30 on the basis of ensuring the wear resistance and lubricating effect, thereby reducing the material cost.

[0028] In the embodiment, the column body 20 is provided with a blind hole, and the base body 10 is provided with a through hole 11 communicating with the opening of the blind hole.

[0029] In the embodiment, the bottom surface of the seat body 10 is provided with the adhesive 40, and the seat body 10 is fixed to the glass through the adhesive 40.

[0030] The seat body 10 is made of polycarbonate and acrylonitrile-butadiene-styrene copolymer mixed engineering plastic alloy (PC+ABS) or polyhexamethylene adipate (PA66), and the seat body 10 is made of any of the above materials, so that the seat body 10 and the adhesive 40 (commonly known as double-sided adhesive tape) have better adhesive effect, which improves the fixing effect between the seat body 10 and the adhesive 40 and the assembly reliability of the glass nail column and the glass.

[0031] In the embodiment, the column body 20 and the seat body 10 are integrally formed, and specifically, the column body 20 and the seat body 10 are integrally formed through an injection molding process.

[0032] Obviously, the above embodiments of the present application are only examples for clearly illustrating the present application, and are not intended to limit the embodiments of the present application. For those skilled in the art, other different forms of changes or modifications can be made on the basis of the above description. Here, it is not necessary and impossible to enumerate all the embodiments. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the claims of the present application.
