Description

Technical Field

[0001] The utility model relates to the technical field of door sealing plugs, and particularly relates to an installation structure for a door sealing plug of a bayonet structure. Background Technique

[0002] In modern vehicle design, door sealing plugs are key components to ensure the sealing performance of bolted doors, which are crucial components affecting vehicle comfort and safety. They provide effective sealing performance, prevent moisture, dust, and noise from entering the vehicle, and protect the door structure from external factors.

[0003] Chinese Utility Model Patent Publication No.: CN 220147117 U, discloses: An inner door panel with a sealing unit. For the inner door panel with a sealing unit, the first storage box sealing back plate, the second storage box sealing back plate, and the third storage box sealing back plate at the rear end of the storage box use sealing bolts to enhance the tightness of the connection between the first storage box sealing back plate, the second storage box sealing back plate, and the third storage box sealing back plate and the interior trim panel, and effectively improve the heat resistance, heat insulation, and sound insulation performance. However, for the inner door panel with a sealing unit, the first storage box sealing back plate, the second storage box sealing back plate, and the third storage box sealing back plate adopt a flat plate structure, with relatively low structural strength, being prone to deformation when subjected to external forces, having insufficient durability, and not being provided with a positioning structure, resulting in low installation efficiency. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide an installation structure for a door sealing plug of a bayonet structure, which can effectively solve the problems in the prior art.

[0006] The positioning component includes a mounting seat, a bushing, a silent ring, a telescopic column, a positioning block, and a spring. The mounting seat is fixedly connected to the bushing at the front end, a silent ring is sleeved on the outer side of the bushing, a telescopic column is provided at the front end of the bushing, the telescopic column is fixedly connected to a positioning block at the front end, and the telescopic column is fixedly connected to a spring at the rear end;

[0012] Preferably, the sealing strip is arranged on the outside of the sound insulation strip, and the diameter of the sealing strip is smaller than that of the sound insulation strip.

[0013] Through the above technical solution, after the sealing plug is assembled with the vehicle door, the gap between the cover edge and the vehicle door is filled and sealed by the sealing strip and the sound insulation strip. When the vehicle bumps, the noise of the internal lines of the vehicle door is blocked by the sealing strip and absorbed and weakened by the sound insulation strip after multiple reflections, and the sealing and noise reduction effect is good.

[0014] Preferably, the silent ring is made of polyurethane material, and the pipe sleeve is slidably connected with the telescopic column.

[0015] Through the above technical solution, a positioning component is provided. When the sealing plug is assembled with the vehicle door, the positioning component is aligned with the positioning hole provided on the vehicle door, and the positioning block is inserted into the positioning hole to assist in the installation.

The first groove, the second groove and the third groove correspond to the routing positions of the wires in the car door. When an external force acts on the sealing plate, it is transmitted to the buffer assembly, and the zigzag deformation plate deforms. In cooperation with the buffer block made of sponge material, the external force is buffered and absorbed, providing buffering and support for the sealing plate, preventing the sealing plate from deforming after being stressed, and improving the durability of the sealing plug.

In the initial state, the length of the positioning assembly 6 is longer, which is more visually aligned with the car door and is convenient for guiding the installation. After the sealing plug is assembled with the car door, the gap between the cover edge 10 and the car door is filled and sealed by the sealing strip 12 and the sound insulation strip 11. When the vehicle jolts, the noise of the internal wires in the car door is blocked by the sealing strip 12 and absorbed and weakened after multiple reflections by the sound insulation strip 11, and the sealing and noise reduction effect is good. When an external force acts on the sealing plate 1, it is transmitted to the buffer assembly 7, and the broken-line-shaped deformation plate 702 deforms. Cooperating with the buffer block 704 made of sponge material, the external force is buffered and absorbed, providing buffering and support for the sealing plate 1, preventing the sealing plate 1 from deforming after being stressed, and improving the durability of the sealing plug.
