Description

Technical Field

[0001] The utility model relates to the technical field of door sealing plugs, and specifically relates to a sealing plug for a bolt-structured door. Background Technique

[0002] In modern vehicle design, the bolt-structured door is a common door structure form. Its characteristic is that various components of the door are firmly connected together through bolts and related fasteners. The door sealing plug is a key component to ensure the sealing performance of the bolt-structured door, a key component affecting vehicle comfort and safety, providing effective sealing performance, preventing moisture, dust and noise from entering the vehicle, and protecting the bolt structure of the door from external factors.

[0003] Chinese Utility Model Patent Publication No.: CN 220147117 U, discloses: A door inner panel with a sealing unit. For this door inner panel with a sealing unit, the first storage box sealing back panel, the second storage box sealing back panel, and the third storage box sealing back panel 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 panel, the second storage box sealing back panel, and the third storage box sealing back panel and the interior trim panel, and effectively improve the heat resistance, heat insulation, and sound insulation performance. However, for this door inner panel with a sealing unit, the first storage box sealing back panel, the second storage box sealing back panel, and the third storage box sealing back panel adopt a flat plate structure, with relatively low structural strength, being prone to deformation when subjected to external forces, and having insufficient durability. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a sealing plug for a bolt-structured door, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by the utility model is: A sealing plug for a bolt-structured door, including a sealing plate. A round hole is opened at the front end of the sealing plate. A cushion seat is fixedly connected to the rear end of the sealing plate. A placement groove is provided at the rear end of the sealing plate. A raised area and a sunken area are provided at the rear end of the sealing plate. A wiring area is provided at the rear end of the sealing plate. A docking post is fixedly connected to the rear end of the sealing plate. A sealing ring is provided at the rear end of the sealing plate.

[0006] Preferably, the round hole corresponds to the cushion seat, and an annularly arranged long groove is opened at the rear end of the cushion seat.

[0007] Through the above technical solution, the round hole and the cushion seat are provided. When assembling, a bolt is used to pass through the round hole to lock and fix the sealing plug to the bolt-structured door. The cushion seat provides support for the sealing plate and provides space for door wiring. The cushion seat is made of fluororubber, with strong weather resistance and not easily aging and deteriorating due to environmental influence.

[0008] Preferably, the thickness of the sealing plate is 1.5 mm to 1.6 mm, and the sealing plate is made of polytetrafluoroethylene material.

[0009] Through the above technical solution, the sealing plate has a relatively thin thickness and is light in weight, which is convenient for assembly. The sealing plate is made of polytetrafluoroethylene material, has strong chemical resistance and high temperature resistance, and is relatively durable.

[0010] Preferably, the placement groove is adapted to the sealing ring, and the sealing ring is made of foamed polyurethane material.

[0011] Through the above technical solution, a sealing ring is provided and installed in the placement groove. The sealing ring is made of foamed polyurethane material. When the sealing plug is fixed to the bolt-structured door, the sealing ring isolates the door from the outside world and has a heat insulation effect at the same time, which is very practical.

[0012] Preferably, the raised areas and the sunken areas are arranged alternately, and the total thickness of the raised areas and the sunken areas is 30 mm to 32 mm.

[0013] Through the above technical solution, the raised areas and the sunken areas are arranged alternately, which improves the structural strength of the sealing plug. The sealing plug is not easily deformed, protects the internal lines of the door, and is also beneficial for transportation and storage.

[0014] Preferably, the wire routing area is arranged on the outer circle of the raised areas and the sunken areas.

[0015] Through the above technical solution, a wire routing area is provided and cooperates with the sunken area, reserving a large space for the internal wiring of the door, which is beneficial for arranging the wiring harness and avoiding short circuits of the wiring harness.

[0016] Preferably, the rear end of the docking post is in a conical structure, and the cushion seat is made of fluororubber.

[0017] Through the above technical solution, a docking post is provided to provide auxiliary positioning when the sealing plug is installed on the bolt-structured door, reducing the assembly difficulty.

[0018] Compared with the prior art, the present invention provides a sealing plug for a bolt-structured door, having the following beneficial effects:

[0019] 1. For the sealing plug for the bolt-structured door, a round hole and a cushion seat are provided. When assembling, a bolt is used to pass through the round hole to lock and fix the sealing plug to the bolt-structured door. The cushion seat provides support for the sealing plate and provides space for the door wiring. The cushion seat is made of fluororubber and has strong weather resistance, and is not easily aged and deteriorated due to the influence of the environment. After being fixed, the cushion seat generates slight deformation to block the bolt gap, improving the sealing performance of the bolt-structured door. The sealing plate has a relatively thin thickness and is light in weight, which is convenient for assembly. The sealing plate is made of polytetrafluoroethylene material, has strong chemical resistance and high temperature resistance, and is relatively durable;

[0020] 2. The sealing plug for a bolt-structured vehicle door is provided with a sealing ring installed in a placement groove. The sealing ring is made of foamed polyurethane material. When the sealing plug is fixed to the bolt-structured vehicle door, the sealing ring isolates the door from the outside and has a heat insulation effect, which is very practical. The raised areas and sunken areas are arranged alternately to enhance the structural strength of the sealing plug, making the sealing plug not easily deformed, protecting the internal wires of the door, and facilitating transportation and storage. A wire routing area is provided and is matched with the sunken area to reserve a large space for routing wires inside the door, facilitating the layout of the wire harness and avoiding short circuits of the wire harness.
