Description

Technical Field

[0001] This utility model relates to the field of sealing rings, specifically to a door sealing system and a vehicle. Background Technology

[0002] A sealing ring is a component used to prevent fluid or solid particles from leaking between adjacent mating surfaces and to prevent external impurities, such as dust and moisture, from entering the interior of machinery and equipment. It is also known as an O-ring or oil seal. It is widely used in many fields such as machinery, automobiles, aerospace, petrochemicals, and electronics, and is a key component ensuring the normal operation and stable performance of equipment. The working principle of a sealing ring is mainly based on its own elasticity and deformation capacity, filling the space between two adjacent mating surfaces to form a sealing barrier and prevent the leakage of fluid or solid particles. When the sealing ring is subjected to pressure, it undergoes elastic deformation, tightly fitting against the mating surfaces, thereby producing a sealing effect.

[0003] The door seals are a very important component of the car's structure. They are usually made of rubber or other elastic materials and are installed on the edges where the door contacts the car body. Their main function is to prevent external dust, moisture and noise from entering the car, while keeping the interior clean, quiet and comfortable.

[0004] For example, the utility model patent with application number CN202421455038.3, entitled "A Door Sealing Component", forms a sealing structure by compressing the bifurcated first lip and second lip. However, this sealing structure only has a single layer of seal and the sealing effect is poor. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A vehicle door sealing system includes a first seal and a second seal;

[0008] The first sealing element includes a first body and a first sealing part and a second sealing part connected to both sides of the first body. The first body is detachably connected to the vehicle body. The first sealing part has a clearance cavity. The free end of the first sealing part abuts against the outer side of the vehicle body. The second sealing part extends outward to the inner side of the door and is inclined toward the door.

[0009] The second seal includes a second body and a top abutment connected to the second body. The second body is detachably connected to the side of the door. The top abutment corresponds to the position of the clearance cavity. When the door is closed, the top abutment abuts against the first seal.

[0010] Furthermore, a mounting boss is provided on the inner side of the opening of the vehicle body, and the first body is detachably connected to the mounting boss.

[0011] The opening direction of the clearance cavity is inclined from the side near the mounting boss toward the outside of the opening on the vehicle body, and the inner side of the first sealing part is spaced apart from the outer side of the mounting boss and the side of the opening on the vehicle body.

[0012] Furthermore, the free end of the first sealing part is connected to an extension arm, the extension arm extending in the same direction as the opening direction of the clearance cavity, and the extension arm abutting against the outer side of the door opening.

[0013] Furthermore, the angle between the extension arm and the outer side of the vehicle body is greater than the deflection angle of the free end of the first sealing part during the sealing process.

[0014] Furthermore, a clearance notch is provided on the inner side of the connection position between the first sealing part and the first body, and the clearance notch corresponds to the outer side of the top surface of the mounting boss.

[0015] Furthermore, the mounting platform is provided with a mounting cavity, and the top surface of the mounting platform is provided with a mounting opening;

[0016] The first body has a first mounting arm on its side. The first mounting arm extends through the mounting opening into the mounting cavity. The free ends of the first mounting arm have first locking blocks on both sides. The first locking blocks abut against the inner wall of the mounting cavity.

[0017] The first body has a push-up slope at one end of its side, and the push-up slope is inclined from the side near the installation opening toward the first locking block.

[0041] Example

[0042] Please refer to Figure 1-3As shown, this embodiment provides a vehicle door sealing system, including a first seal 3 and a second seal 4. The first seal 3 includes a first body 31 and a first sealing portion 32 and a second sealing portion 33 connected to both sides of the first body 31. The first body 31 is detachably connected to the vehicle body 1. A clearance cavity 321 is formed in the first sealing portion 32, and the free end of the first sealing portion 32 abuts against the outer side of the vehicle body 1. The second sealing portion 33 extends outward to the inner side of the vehicle door 2 and is inclined towards the vehicle door 2. The second seal 4 includes a second body 41 and abutting portion 42 connected to the second body 41. The second body 41 is detachably connected to the side of the vehicle door 2. Please refer to... Figure 2 As shown, the top abutment 42 corresponds to the clearance cavity 321. When the door 2 is closed, the top abutment 42 abuts against the first sealing part 32. The filling position of the first sealing member 3 is the position where it abuts against the top abutment 42. In this embodiment, the clearance cavity 321 is provided with an exhaust hole 322 to allow the air inside the clearance cavity 321 to be discharged after compression.

[0043] When the door 2 is closed, the top abutment 42 and the first sealing part 32 abut against each other, squeezing the clearance cavity 321 and expelling the air inside the clearance cavity 321. This causes the outer side of the first sealing part 32 to wrap around the end of the top abutment 42, effectively increasing the contact area between the top abutment 42 and the first sealing part 32 and improving the sealing effect. Furthermore, the inner side of the door 2 abuts against the end of the second sealing member 4, and the second sealing member 4 performs a secondary seal on the gap of the door 2 inside the door 2, further improving the sealing effect on the gap between the door 2 and the body 1.

[0044] Please refer to Figure 2 As shown, specifically, a mounting boss 11 is provided on the inner side of the opening of the vehicle body 1, and the first body 31 is detachably connected to the mounting boss 11. The opening direction of the clearance cavity 321 is inclined from the side closer to the mounting boss 11 toward the outer side of the opening of the vehicle body 1. The inner side of the first sealing part 32 is spaced apart from the outer side of the mounting boss 11 and the side of the opening of the vehicle body 1. The first sealing part 32, the outer side of the mounting boss 11, and the side of the opening of the door 2 form a triangular distribution structure. The space between the outer side of the mounting boss 11, the side of the opening of the vehicle body 1, and the first sealing part 32 provides bending space for the first sealing part 32. When the door 2 is closed, and the top abutment 42 is pressing the first sealing part 32, the first sealing part 32 can bend backward, improving the flexibility of the first sealing part 32 and ensuring that the first sealing part 32 and the top abutment 42 can have a larger range of contact.

[0045] Furthermore, an extension arm 323 is connected to the free end of the first sealing part 32. The extension arm 323 extends in the same direction as the opening of the clearance cavity 321, and the extension arm 323 abuts against the outer side of the opening of the door 2. The extension arm 323 effectively extends the length of the first sealing part 32, increases the contact area between the first sealing part 32 and the vehicle body 1 when the door is closed, and avoids gaps between the first sealing part 32 and the vehicle body 1, which would affect the sealing effect. In this embodiment, the angle between the extension arm 323 and the outer side of the vehicle body 1 is greater than the deflection angle of the free end of the first sealing part 32 during the sealing process. That is, the extension arm 323 is set with a larger angle so that when the door is closed, the angle at which the free end of the first sealing part 32 drives the extension arm 323 to deflect is less than the angle between the extension arm 323 and the outer side of the vehicle body 1 when the door is closed. When the door is closed, the extension arm 323 will not lift up, ensuring that the extension arm 323 is always in contact with the side of the opening of the vehicle body 1. Simultaneously, the extension arm 323 applies an outward pushing force to the first sealing part 32, causing the position of the first sealing part 32 to shift outward. During the closing process, this allows the first sealing part 32 to contact the top abutment part 42 even before the door 2 is fully closed. In the closed state, under the counter-pushing force of the extension arm 323, the first sealing part 32 moves closer to the top abutment part 42, effectively increasing the contact area between them. During the opening process, as the door 2 moves away from the first sealing part 32, the extension arm 323 pushes the first sealing part 32 towards the top abutment part 42, extending the contact time between them and effectively prolonging the sealing time and improving the sealing effect. Please refer to... Figure 2 As shown, the filling position of the extension arm 323 is the position where it contacts the top of the vehicle body 1.

[0046] Specifically, a clearance notch 324 is provided on the inner side of the connection position between the first sealing part 32 and the first body 31, and the clearance notch 324 corresponds to the outer edge of the top surface of the mounting boss 11. The clearance notch 324 makes way for the positioning outer side of the mounting boss 11, so that the first sealing part 32 can be bent more easily toward the outer side of the mounting boss 11 and the opening side of the vehicle body 1, thereby improving the flexibility of the first sealing part 32.

[0047] The mounting platform has a mounting cavity 111, and a mounting opening 112 is formed on the top surface of the mounting platform. A first mounting arm 311 is provided on the side of the first body 31, extending through the mounting opening 112 into the mounting cavity 111. First locking blocks 312 are provided on both sides of the free end of the first mounting arm 311, and the first locking blocks 312 abut against the inner wall of the mounting cavity 111. The first body 31 engages with the mounting platform via the first locking blocks 312. In this embodiment, a V-shaped notch 313 is formed in the middle of the first locking block 312, allowing the two ends of the first locking block 312 to better press against each other and move in and out of the mounting opening 112, reducing the assembly difficulty of the first body 31.

[0048] Furthermore, a pushing slope 314 is provided at one end of the side of the first body 31. The pushing slope 314 is inclined towards the first locking block 312 from the side near the mounting opening 112. That is, the distance between the pushing slope 314 and the first locking block 312 on the same side is smaller than the distance between the top surface of the mounting platform and the mounting cavity 111. This allows the mounting platform to apply a pushing force towards the door 2 to the pushing slope 314 when the first body 31 is in the assembled state. This force is then transmitted to the second sealing part 33, causing the second sealing part 33 to move towards the inner side of the door 2. This further improves the tightness of the fit between the second sealing part 33 and the inner side of the door 2, and enhances the secondary sealing effect.

[0049] In this embodiment, a bending notch 331 is provided on the outer side of the second sealing part 33. The bending notch 331 improves the flexibility of the second sealing part 33, allowing the second sealing part 33 to bend in the opposite direction when its free end is abutting against the inner side of the door 2, thus avoiding affecting the closing effect of the door 2. Please refer to... Figure 2 As shown, the filling position of the second sealing part 33 is the position where it abuts against the door 2.

[0050] Specifically, an outwardly extending mounting portion 21 is provided on the outer side of the door 2, and a mounting channel 211 is provided on the mounting portion 211, in which the second body 41 is embedded. A movable channel 421 is provided on the top abutment portion 42, which improves the flexibility of the top abutment portion 42, allowing the top abutment portion 42 to bend in the opposite direction when it is in contact with the first sealing portion 32, thereby increasing the contact area between the top abutment portion 42 and the first sealing portion 32 and improving the sealing effect. An outwardly extending inner clamping arm 422 is provided on one side of the top abutment portion 42, which extends to the inner side of the mounting portion 21 and abuts against the inner side of the mounting portion 21. The connection position between the inner clamping arm 422 and the top abutment portion 42 is spaced apart from the end of the mounting portion 21. The inner clamping arm 422, located inside the mounting portion 21, does not abut against the mounting portion 42 but applies tension to the abutting portion 42, ensuring that the abutting portion 42 can stably abut against the first sealing portion 32. Simultaneously, the end of the inner clamping arm 422 is spaced apart from the end of the mounting portion 21, further improving the flexibility of the abutting portion 42 and facilitating small-range movement. Furthermore, the other side of the abutting portion 42 extends to the outside of the mounting portion 21 and is provided with an outwardly extending outer clamping arm 423. The outer clamping arm 423 extends to the outside of the mounting portion 21 and abuts against the outside of the mounting portion 21. The outer clamping arm 423 limits the abutting portion 42 on the outside and cooperates with the inner clamping arm 422 to improve the installation stability of the second seal 4. Please refer to... Figure 2 As shown, the outer clamping arm 423 and the inner clamping arm 422 are positioned at their respective contact points with the top of the door 2.

[0051] Specifically, a wedge-shaped protrusion 212 is provided on one side of the mounting channel 211. The side of the second body 41 has a wedge-shaped notch 411 that matches the wedge-shaped protrusion 212. The second body 41 engages within the mounting channel 211, and the wedge-shaped protrusion 212 is embedded within the wedge-shaped notch 411. The wedge-shaped protrusion 212 limits the position of the second body 41, ensuring that the second body 41 can be stably installed within the mounting channel 211.

[0052] Please refer to Figure 3 As shown, in this embodiment, a third sealing element 5 is also provided on the side of the door 2, and an assembly channel 22 is provided. The assembly channel 22 is located inside the mounting part 21, and an assembly opening 221 is provided on the assembly channel 22. The third sealing element 5 includes a third body 51, which extends through the assembly opening 221 into the assembly channel 22 and engages with the assembly channel 22. An O-ring seal 52 is provided on the third body 51, and the end of the O-ring seal 52 abuts against the first body 31. A triple seal is achieved through the O-ring seal 52 and the first body 31, further improving the sealing effect of the door 2. The filling position of the O-ring seal 52 is the position where it abuts against the first body 31.

[0053] Please refer to Figure 1 As shown, this embodiment also discloses a vehicle that uses the aforementioned door 2 sealing system. In this embodiment, the vehicle is a bus, and door 2 is a sliding door; similarly, other types of vehicles can also be used.
