The molding body 15 is disposed on the molding frame 14 and adapted to block the first via hole 11. Specifically, in this embodiment, the molding body 15 is fixed on the molding frame 14 by clamping or welding, and shields the first via hole 11, so as to shield the connecting bolt 2, and external pedestrians can only see the molding body 15 but cannot see the first via hole 11 or the connecting bolt 2 inside, thereby improving the aesthetic property of the molding 1.

Referring to fig. 3 and 4, in order to facilitate the installation of the connecting bolt 2 on the molding frame 14, the molding frame 14 is further provided with a second through hole 16 through which the first bolt head 22 passes and a connecting channel 17 which communicates the first through hole 11 and the second through hole 16 and through which the bolt rod 21 moves. When the connecting bolt 2 is installed on the trim strip framework 14 by a worker, the first bolt head 22 firstly penetrates through the second through hole 16, then the connecting bolt 2 is translated to enable the bolt rod 21 between the first bolt head 22 and the second connector to move along the extending direction of the connecting channel 17 and enter the first through hole 11, at the moment, the first bolt head 22 and the second bolt head 23 are respectively arranged on two sides of the trim strip framework 14 in the thickness direction, and connection between the connecting bolt 2 and the trim strip framework 14 is completed, so that the connecting bolt is convenient and fast.

Further, in order to enhance the stability of the connecting bolt 2 and reduce the possibility that the connecting bolt 2 is separated from the first via hole 11, a limiting protrusion 18 is further disposed on the connecting channel 17. Specifically, in this embodiment, two inner walls opposite to the connecting channel 17 are provided with an arc-shaped limiting protrusion 18, and the two limiting protrusions 18 are arranged oppositely. When staff's translation connecting bolt 2 runs into spacing arch 18 in connecting channel 17, promote connecting bolt 2 hard and just enable shank of bolt 21 through spacing arch 18, consequently push away shank of bolt 21 behind connecting channel 17 entering first via hole 11, connecting bolt 2 can stably set up in first via hole 11 department, has effectively restricted shank of bolt 21 and has broken away from first via hole 11.

In order to further reduce the possibility that the connecting bolt 2 is separated from the molding frame 14, an elastic stop piece 19 is arranged on the inner peripheral wall of the second through hole 16, when the elastic stop piece 19 is in a normal state, the elastic stop piece 19 shields the second through hole 16, and the first bolt head 22 cannot pass through the second through hole 16; when the elastic stopper 19 is in a stressed state, the elastic stopper 19 is stressed to be elastically deformed so as to open the second through hole 16, so that the first bolt head 22 can pass through the second through hole 16. Specifically, in this embodiment, the elastic stopper 19 is an elastic plate, and when the elastic plate is in a normal state, a plate surface of the elastic plate is perpendicular to the thickness direction of the decoration strip framework 14, and blocks the second via hole 16; when the elastic plate is subjected to a force parallel to the thickness direction of the trim rib 14, the elastic plate is bent and deformed to open the second through hole 16, so that the first bolt head 22 can pass through the second through hole 16.

Referring to fig. 1 and 2, as a modified solution, it is preferable that the side of the second bolt head 23 away from the first bolt head 22 is provided with a waterproof gasket 3. Specifically, in this embodiment, the waterproof gasket 3 is sleeved on the bolt rod 21. When the trim subassembly was installed on door panel beating 4, improved the waterproof nature of trim 1 and door panel beating 4 junction through waterproof gasket 3.

The embodiment of the application also provides a car door, and this car door includes door panel beating 4 and installs the trim subassembly on door panel beating 4, and this trim subassembly is the trim subassembly that this application provided, and shank of bolt 21 passes door panel beating 4 and cooperates in order to fix the trim subassembly on door panel beating 4 with the nut. Because the door according to the embodiment of the application is provided with the trim assembly, the installation efficiency of the door is greatly improved, and the labor cost of the door is reduced.
