[0017] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the appended claims of the application equally.
[0018] The original upper frame of the car needs to be rolled and stamped to form a whole, but this process has a high production cost. In order to save costs, the stamping process is saved during the production of the car frame. This process can save tens of millions of production costs. After saving this process, the installation space of the decorative strips of the car frame becomes smaller, and the original connection structure cannot be installed. At the same time, the installation space of the sealing structure is also greatly reduced. In order to solve this problem, it is necessary to design a new upper decorative strip structure to assemble the car frame.
[0019] An embodiment of the present invention relates to a front upper trim strip, such as Figure 1 As shown, the decorative strip body 1 is provided with an inwardly recessed connection portion 2 for connection with the automobile frame, and at the same time, a space avoidance portion 4 is designed at the location where the front triangular window of the automobile is installed, which greatly reduces the space occupied by the decorative strip body 1 and facilitates the installation of sealing and mud grooves. At the same time, a triangular window connection portion 5 is provided to reduce the space occupied by the triangular window installation structure, thereby enabling the frame structure to save a precision stamping process and greatly reducing the production cost.
[0020] like Figure 3 As shown, in order to ensure that the decorative strip body is docked with the triangular window structure, the triangular window connecting part 5 is designed to be an inclined air-avoiding extension 8, and the inclined air-avoiding extension 8 is inclined toward the frame direction, so that a misalignment is formed between the triangular window and the decorative strip, making the assembly of the two more compact. At the same time, in order to ensure that the triangular window can be connected to the decorative strip, an inner recess 9 is provided on the inclined air-avoiding extension 8, and the inner recess 9 can be used to install a connecting card 10, which is connected to the triangular window through the extended connecting ear 11 on the connecting card 10. At the same time, a barb 12 is provided, which can improve the assembly strength of the decorative strip and the connecting card 10.
[0021] like Figure 4 As shown, when the automobile frame sheet metal 14 is connected to the decorative strip body 1, the expansion bolt 15 is first driven into the connection hole of the automobile frame sheet metal 14, and then the sealing strip is installed on the upper side of the decorative strip body 1, and then the decorative strip body 1 equipped with the sealing strip is attached to the automobile frame sheet metal 14, and finally the connecting nail 16 inserted with the expansion bolt 15 is installed in the connecting hole of the concave connecting part 2. After the assembly is completed, other components are installed. This installation method greatly saves installation space, while ensuring the sealing performance of the decorative strip, and can also simplify the installation steps of the entire decorative strip, making it convenient for workers to operate.
[0022] In order to facilitate the forming of the concave connecting part 2, a straight-shaped through hole is provided on both sides of the stamped concave connecting part 2 to simplify the stamping process. At the same time, the connecting hole in the center of the concave connecting part 2 can be a circular hole or an elliptical hole. When connecting, the connecting nail 16 must still have a gasket that fits the concave connecting part 2.
[0023] In order to ensure the aesthetically pleasing structure of the center column end of the decorative strip, a connecting rib 7 is provided on the decorative cover 3 to assist in connecting the center column cover body. At the same time, in order to improve the aesthetics, a closed space is formed at the end of the decorative cover 3 to conceal the end section of the decorative strip body 1.
[0024] The rectangular notch 13 is designed to facilitate the installation of the mud groove and the sealing member.
[0025] As a supplement to the present technical solution, the connecting card 10 is a folded card structure, the folded gap forms a card slot matching the inner recess 9, the folded upward part is provided with an inclined bend, and the inclined bend is provided with no less than two barbs 12.
[0026] As a supplement to the present technical solution, the cross section of the triangular window connecting portion 5 is in the shape of a triangular frame.
[0027] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the described specific embodiments or replace them in a similar manner without departing from the scope defined by the spirit of the present invention.
