The integrated shark fin antenna is installed upward from the bottom of the roof of the vehicle body and cannot independently achieve the sealing and waterproofing function of the roof. The shark fin decorative cover of this type of vehicle model not only needs to achieve the styling effect, but also needs to bear the sealing and waterproofing function of the roof area of ​​the vehicle body.

[0003] The shark fin decorative cover of existing market models adopts a pure bonding solution with double-sided tape and the top cover. After the shark fin decorative cover is integrally injection molded, double-sided tape is used to bond it to the corresponding matching position of the top cover, in order to achieve the sealing and waterproof function of the top cover area. However, the assembly pressure is not easy to meet because the shark fin decorative cover is located above the top cover of the vehicle body and the position of the whole vehicle is high, which is not easy for employees to press manually; because the shark fin decorative cover is a styling part, in order to adapt to the overall styling style, the shape of the outer surface is complex, and it is not easy to use tooling equipment to press evenly.

[0034] The existing technology has the following disadvantages: the shark fin decorative cover of the existing market models adopts a pure bonding solution with double-sided tape and the top cover. After the shark fin decorative cover is integrally injection molded, double-sided tape is used to bond it to the corresponding matching position of the top cover, in order to achieve the sealing and waterproof function of the top cover area. However, the assembly pressure is not easy to meet because the shark fin decorative cover is located above the top cover of the vehicle body and the position of the whole vehicle is high, which is not easy for employees to press manually; because the shark fin decorative cover is a styling part, in order to adapt to the overall styling style, the shape of the outer surface is complex, and it is not easy to use tooling equipment to press evenly. The production site cannot fully meet the pressure of the double-sided tape and there is a risk of market complaints caused by debonding in the later stage.

[0035] In view of the defects of the prior art, the present application provides a first connecting piece integrally formed with the circumferential flange, and the shark fin shell is firmly connected to the vehicle body roof cover through the first connecting piece, so that the first connecting piece is used to provide the shark fin shell with a biasing force toward the vehicle body roof cover, thereby avoiding the phenomenon of unstable connection when only using adhesive parts for connection; and provides a third connecting piece, which is connected to the first connecting piece to ensure the clamping force between the shark fin shell and the vehicle body roof cover, so that when installing the shark fin shell, there is no need to press specifically to meet the requirements of the adhesive part assembly pressure, thereby avoiding the adhesive part affecting the feel of use due to reasons such as assembly pressure and ambient temperature.
