Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive door rubber sleeve technology, and in particular to a dustproof automotive door rubber sleeve. Background Technology
[0002] Door rubber covers are rubber seals installed on the edges of car doors or at the junction of the door and the car body. They mainly achieve dustproof function through physical structure and material properties, while also providing auxiliary functions such as sound insulation, cushioning, and waterproofing. Door rubber covers are an important part of the automotive sealing system and are commonly found on door frames, door glass edges, and near door hinges.
[0003] The prior art, patent publication number CN218805158U, discloses a car door sealing strip composed of a rubber body and a metal skeleton. The rubber body includes a solid rubber and a sponge rubber that are vulcanized together, which is simple and reliable to assemble and has strong sealing performance. However, in actual use, after the car door is closed, the rain guard is in close contact with the door sheet metal, and most of the rain and dust on the door will be blocked by it. However, when the rain guard is damaged, since the rain guard and the sponge rubber are fixedly connected, the entire sealing sleeve needs to be replaced, resulting in high maintenance costs. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a dustproof rubber cover for car doors.
[0005] This utility model is achieved through the following technical solution:
[0006] A dustproof rubber cover for a car door includes a first body, a second body, and multiple toothed strips. The first body, the second body, and the multiple toothed strips are vulcanized integral structures. A rain shield is movably disposed on the side of the second body away from the first body. Multiple inserts are fixedly connected to one side of the rain shield. A connecting assembly is disposed inside the second body. The connecting assembly includes a connecting sleeve, a lead screw, two threaded sleeves, multiple first connecting tubes, and multiple second connecting tubes. One end of the lead screw passes through the connecting sleeve and the multiple inserts. Both threaded sleeves are threadedly connected to the lead screw. The two ends of the multiple second connecting tubes are fixedly connected to the connecting sleeve and the second body, respectively. One end of the multiple first connecting tubes is fixedly connected to the connecting sleeve and the second body, respectively.
[0007] Optionally, in one possible implementation, a perforated plate is fixedly embedded in the top of the rain shield. It can be seen that in the above technical solution, the perforated plate can prevent external dust from entering the rain shield.
[0008] Optionally, in one possible implementation, gaskets are fixedly fitted onto each of the plurality of cannulas, and the outer sides of the gaskets are in contact with the connecting sleeve. It can be seen that in the above technical solution, the gaskets can improve the sealing between the cannulas and the connecting sleeve, thereby preventing rainwater from leaking out through the gaps between the cannulas and the connecting sleeve.
[0009] Optionally, in one possible implementation, a carbon fiber composite plate is fixedly embedded inside the first housing. It can be seen that in the above technical solution, the carbon fiber composite plate can reduce weight while maintaining strength.
[0010] Optionally, in one possible implementation, both the first and second housings are composed of a protective layer, a support layer, a buffer layer, and an adhesive layer, and the protective layer, support layer, buffer layer, and adhesive layer are fixed in sequence. Optionally, in one possible implementation, the protective layer is a component made of EPDM rubber, and the support layer is a component made of high-hardness EPDM rubber.
[0011] Optionally, in one possible implementation, the support pad is an EPDM sponge rubber component, and the bonding layer is a silicone rubber component.
[0012] The technical effects and advantages of this utility model are as follows:
[0013] This utility model uses a toothed rack fitted onto the car door sheet metal, ensuring a tight contact between the rain shield and the sheet metal. This effectively blocks most of the rainwater and dust from the door. By rotating the threaded sleeve and moving it away from the lead screw, the fixing between the lead screw and the connecting sleeve is released. The lead screw is then moved horizontally away from the multiple inserts to disassemble and replace the rain shield. Similarly, the rain shield can be installed. The operation is simple, facilitating the disassembly and assembly of the rain shield and reducing maintenance costs.
[0014] Meanwhile, rainwater enters the connecting sleeve through the first connecting pipe, then enters the rain shield through the insert pipe, and finally exits through the mesh plate, thus guiding the rainwater to drain quickly. The carbon fiber composite plate can reduce weight while ensuring strength, and the mesh plate can prevent external dust from entering the rain shield. The protective layer has dustproof, scratch-proof, weather-resistant and anti-aging functions, the support layer has structural support and tolerance compensation functions, the buffer layer has elastic buffering and micro-dust filtration functions, and the bonding layer has sealing and high and low temperature resistance functions. The structure is simple and easy to use. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and preferred embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0023] Example 1: As Figure 1-4 As shown, a dustproof car door rubber cover includes a first body 1, a second body 2, and multiple toothed strips 5. The first body 1, the second body 2, and the multiple toothed strips 5 are vulcanized integral structures. A rain shield 3 is movably arranged on the side of the second body 2 away from the first body 1. Multiple insertion tubes 8 are fixedly connected to one side of the rain shield 3. A connecting assembly 4 is provided inside the second body 2. The connecting assembly 4 includes a connecting sleeve 401, a lead rod 402, two threaded sleeves 403, multiple first connecting tubes 404, and multiple second connecting tubes 405. One end of the lead rod 402 passes through the connecting sleeve 401 and the multiple insertion tubes 8. The two threaded sleeves 403 are threadedly connected to the lead rod 402. The two ends of the multiple second connecting tubes 405 are fixedly connected to the connecting sleeve 401 and the second body 2, respectively. One end of the multiple first connecting tubes 404 is fixedly connected to the connecting sleeve 401 and the second body 2, respectively.
[0024] In use, the toothed rack 5 is fitted onto the door sheet metal, and the rain shield 3 is in close contact with the door sheet metal, so that most of the rain and dust on the door will be blocked by it. When the rain shield 3 is damaged, the threaded sleeve 403 is rotated and moved away from the lead screw 402, thereby releasing the fixation between the lead screw 402 and the connecting sleeve 401. The lead screw 402 is moved horizontally and moved away from the multiple insertion tubes 8, thereby releasing the fixation between the rain shield 3 and the second sleeve 2. The rain shield 3 is moved horizontally and the multiple insertion tubes 8 are moved away from the second sleeve 2, so that the rain shield 3 can be disassembled and replaced. Similarly, the rain shield 3 can be installed. The operation is simple and convenient for disassembling and assembling the rain shield 3, reducing maintenance costs.
[0025] Example 2: Figure 1-5 As shown, a dustproof car door rubber cover has a mesh plate 7 fixedly embedded in the top of the rain shield 3, and multiple inserts 8 are all fixedly fitted with gaskets 9, and the outer sides of the multiple gaskets 9 are in contact with the connecting sleeve 401. A carbon fiber composite plate 6 is fixedly embedded in the inside of the first body 1.
[0026] Furthermore, both the first set 1 and the second set 2 are composed of a protective layer 10, a support layer 11, a buffer layer 12 and an adhesive layer 13, and the protective layer 10, the support layer 11, the buffer layer 12 and the adhesive layer 13 are fixed in sequence. The protective layer 10 is a component made of EPDM rubber, the support layer 11 is a component made of high-hardness EPDM rubber, the support pad layer 11 is a component made of EPDM sponge rubber, and the adhesive layer 13 is a component made of silicone rubber.
[0027] During use, rainwater enters the connecting sleeve 401 through the first connecting pipe 404, then enters the rain shield 3 through the insert pipe 8, and finally exits through the mesh plate 7, thus guiding the rainwater to drain quickly. The carbon fiber composite plate 6 can reduce weight while ensuring strength. The mesh plate 7 can prevent external dust from entering the rain shield 3. The gasket 9 can improve the sealing between the insert pipe 8 and the connecting sleeve 401. The protective layer 10 has dustproof, scratch-proof, weather-resistant and anti-aging functions. The support layer 11 has structural support and tolerance compensation functions. The buffer layer 12 has elastic buffer and micro-dust filtration functions. The bonding layer 13 has sealing and high and low temperature resistance functions. The structure is simple and easy to use.
[0028] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
