Description

Technical Field

[0001] The present invention relates to the technical field of vehicle door assemblies, and more particularly, to a door sealing device and a vehicle. Background Art

[0002] The existing technology has shown significant defects in the waterproof sealing design of commercial vehicle doors, mainly including: when the waterproof film is pasted to the door sheet metal, wrinkles are easily formed, resulting in poor gap sealing. In addition, due to the cold flow phenomenon of butyl rubber, it is prone to deformation. Even if high-rigidity materials are selected, it is still difficult to avoid sealing failure in a non-flat state, leading to rain leakage problems; moreover, when repairing the internal components of the door, it is extremely difficult to remove the butyl rubber, often requiring the destruction of the waterproof film, increasing the maintenance cost and complexity; finally, when facing the inner door sheet metal with a large area, irregular surface and densely distributed component fixing holes, the traditional waterproof cover structure is not only costly, but also difficult to achieve effective sealing, and the assembly difficulty is also significantly increased.

[0003] The XPE waterproof film disclosed in CN209381753U in the prior art has waterproof properties, but it relies on butyl rubber strips for bonding and does not solve the sealing defects caused by improper operation. Although CN113861578A proposes a solution to improve the rigidity of butyl rubber, it fails to overcome the waterproof failure caused by the deformation of the rubber strip or uneven pasting, and does not mention the convenience of maintenance. The waterproof cover structures involved in CN114274746A and CN208484515U are only applicable to local small areas. For larger and more complex sealing requirements, their cost-effectiveness is low, the assembly difficulty and the requirements for the skills of operators are too high.

[0004] In summary, the waterproof sealing effect of the existing technology is limited, especially in the case of densely distributed internal components of the door, irregular surfaces, and large-scale sealing requirements, and there are problems of inconvenient maintenance and excessive costs. For the above technical problems, no effective solutions have been proposed yet. Summary of the Invention

[0043] In combination with Figures 1 to 10 As shown, according to a specific embodiment of the present invention, a door sealing device is provided

[0044] Specifically, asFigure 1 , Figure 2 As shown in Figure 2 , a door seal device includes: a waterproof film 10, one side of the waterproof film 10 is used to connect with the inner door panel 200; a connecting plate 20, the connecting plate 20 is connected to the other side of the waterproof film 10, and the connecting plate 20 is connected to the inner door panel 200; a sealing strip 30, the sealing strip 30 is located between the waterproof film 10 and the connecting plate 20, and the sealing strip 30 is arranged along the circumferential direction of the connecting plate 20.

[0045] In this embodiment, by directly connecting the waterproof film 10 with the inner door panel 200, a preliminary waterproof structure is established. On this basis, the connecting plate 20 is connected to the other side of the waterproof film 10, and the connecting plate 20 is also connected to the inner door panel 200, realizing the double stability of the door seal device in structure, ensuring the integrity and durability of the sealing structure. Especially when the vehicle encounters vibrations or impacts during driving, it can maintain a good sealing state. By arranging the sealing strip 30 between the waterproof film 10 and the connecting plate 20, and the sealing strip 30 is arranged along the circumferential direction of the connecting plate 20, using the compression deformation of the sealing strip 30 when being pressed and the high resilience characteristic after the pressure is released, when the connecting plate 20 is connected to the inner door panel 200, under the pushing of the elastic reaction force of the sealing strip 30 itself, the waterproof film 10 is closely attached to the circumference of the inner door panel 200, achieving the technical effect of effectively preventing rainwater from splashing into the interior during the rain, and solving the technical problems in the traditional door sealing structure, such as the poor waterproof effect caused by the deformation, uneven assembly of the sealing strip during the assembly process or the performance attenuation after long-term use, and the interior being damp or even damaged.

[0046] Combined with Figure 5 , Figure 6 As shown in Figure 6 , the sealing strip 30 includes: an intermediate layer 31, the intermediate layer is made of ethylene propylene diene monomer (EPDM) foam rubber; a surface layer 32, the surface layer 32 is arranged along the circumferential direction of the intermediate layer 31, and the surface layer 32 is made of butyl rubber.

[0047] Specifically, the middle layer 31 made of ethylene propylene diene monomer (EPDM) foam rubber can deform when subjected to external compression due to the inherent high elasticity and resilience of its material, and quickly return to its original state when the external force is removed, ensuring that the sealing strip 30 can closely fit each connection surface during assembly and use; butyl rubber is a material with low air permeability and high barrier properties, which can form a stable bond with the surfaces of the vehicle door inner panel 200 and the connecting plate 20. Even under extreme temperatures, it can maintain a good bonding effect, avoiding problems such as strip aging or a decrease in adhesive force caused by temperature changes. By combining two rubber materials with different properties in the sealing strip 30, an overall optimization of sealing performance, bonding stability, durability, and resilience is achieved. The middle layer 31 of EPDM foam rubber provides the necessary elasticity to meet the deformation requirements during assembly, while the surface layer 32 of butyl rubber ensures long-term stable bonding between the strip and other components. The above two materials are extruded synchronously through a special concentric die orifice.

[0048] Further, the diameter of the middle layer 31 is d1, where 4 mm ≤ d1 ≤ 5 mm, and the outer diameter of the surface layer 32 is d2, where 6.5 mm ≤ d2 ≤ 7.5 mm.

[0049] As Figure 4 shown, a receiving groove 21 is provided on one side of the connecting plate 20 facing the vehicle door inner panel 200. The receiving groove 21 is arranged along the circumferential direction of the connecting plate 20, and the sealing strip 30 is located in the receiving groove 21.

[0050] Specifically, the receiving groove 21 can ensure that the sealing strip 30 has a more accurate and stable positioning, avoiding the offset or uneven extrusion of the strip during the assembly process, thereby providing a more uniform and tight contact surface at the microscopic level, enhancing the overall sealing performance of the vehicle door. The receiving groove 21 is arranged along the circumferential direction of the connecting plate 20, providing a fixed track for the sealing strip 30, simplifying the assembly process, enabling the sealing strip 30 to be quickly and accurately positioned and installed during the assembly process, and improving production efficiency.

[0051] As Figure 3 shown, a plurality of first fixing holes 11 are provided in the circumferential direction of the waterproof film 10, and a plurality of second fixing holes 22 are provided in the circumferential direction of the connecting plate 20. The plurality of first fixing holes 11 and the plurality of second fixing holes 22 are arranged in one-to-one correspondence. The waterproof film 10 and the connecting plate 20 are fixedly connected to the vehicle door inner panel 200 through fixing members sequentially passing through the second fixing holes 22 and the first fixing holes 11, and the sealing strip 30 is located outside the first fixing holes 11 and the second fixing holes 22.

[0052] In this embodiment, the connecting plate 20 and the waterproof film 10 are fixedly connected to the inner door panel 200 by bolts successively passing through the second fixing holes 22 and the first fixing holes 11. When the bolts apply a clamping force to the connecting plate 20 and the waterproof film 10, the sealing strip 30 is compressed. By utilizing the compression deformation of the sealing strip 30 when being pressed and its high resilience characteristic after the pressure is released, when the connecting plate 20 is connected to the inner door panel 200, under the pushing of the elastic reaction force of the sealing strip 30 itself, the waterproof film 10 is closely attached to the periphery of the inner door panel 200, achieving the technical effect of effectively preventing rainwater from splashing into the interior during rain. At the same time, the corresponding setting of the first fixing holes 11 and the second fixing holes 22, as well as the insertion connection of the fixing parts, ensure the accurate positioning and fixing of the waterproof film 10 and the connecting plate 20 relative to the inner door panel 200, avoiding sealing failure caused by inaccurate positioning or insecure fixing, and improving the overall stability and reliability of the door sealing device.

[0053] Further, the waterproof film 10 includes: a film body 12, the film body 12 is arranged to be adapted to the shape of the inner door panel 200, and a plurality of first fixing holes 11 are arranged at intervals in the circumferential direction of the film body 12; a plurality of film pieces 13, the plurality of film pieces 13 are arranged on the side of the film body 12 facing the connecting plate 20, and the film body 12 is connected to the connecting plate 20 through the plurality of film pieces 13.

[0054] In this embodiment, the circumferences of the waterproof film 10 and the connecting plate 20 are connected to the inner door panel 200 through fixing parts. Most areas of the film body 12 of the waterproof film 10 are bonded to the connecting plate 20 through the film pieces 13, avoiding the risk of damage or water leakage of the waterproof film that may be brought by traditional fixing means (such as screws, rivets, etc.). The bonding property of the film pieces 13 ensures a smooth transition between the waterproof film and the connecting plate, forming a continuous waterproof barrier. The shape of the film body 12 matches that of the inner door panel 200, and it can closely fit the contour of the inner door panel, ensuring seamless coverage of the waterproof film 10 in the entire door area, avoiding gaps or warping caused by inconsistent shapes, and thus significantly improving the sealing performance of the waterproof film.

[0055] As Figure 4 shown, the connecting plate 20 includes: a connecting plate body 23, a plurality of second fixing holes 22 are arranged at intervals in the circumferential direction of the connecting plate body 23, the connecting plate body 23 is connected to the film body 12 through the plurality of film pieces 13, and the connecting plate body 23 is arranged to be adapted to the shape of the inner door panel 200; a plurality of third fixing holes 24, the plurality of third fixing holes 24 are arranged at intervals along the circumferential direction of the connecting plate body 23, the plurality of third fixing holes 24 and the plurality of second fixing holes 22 are arranged at intervals, and the third fixing holes 24 are used for fixing door interior fasteners.

[0056] Specifically, the shape of the connecting plate body 23 is adapted to the inner door panel 200, ensuring a tight installation and improving the overall stability and waterproof performance of the door sealing structure. At the same time, it is bonded to the film body 12 through the film 13, further strengthening the seal between the waterproof film and the connecting plate, preventing moisture from penetrating through the gaps, and ensuring the effectiveness and long-term stability of the door sealing structure. The setting of the third fixing hole 24 provides a fixing interface for the door interior trim buckle, making the installation of the interior trim more convenient and fast. There is no need to additionally drill holes on the inner door panel, reducing the damage to the structural integrity of the inner door panel, and at the same time ensuring the firm connection between the interior trim and the door.

[0057] Furthermore, the waterproof film 10 further includes at least two fourth fixing holes 14 and at least three fifth fixing holes 15. The fourth fixing holes 14 and the fifth fixing holes 15 are arranged at a distance. The connecting plate 20 further includes at least two sixth fixing holes 25 and at least three seventh fixing holes 26. At least two of the fourth fixing holes 14 are arranged corresponding to at least two of the sixth fixing holes 25. At least two of the fourth fixing holes 14 and at least two of the sixth fixing holes 25 are used to fix the electrical controller. At least three of the fifth fixing holes 15 are arranged corresponding to at least three of the seventh fixing holes 26. At least three of the fifth fixing holes 15 and at least three of the seventh fixing holes 26 are used to fix the door glass lifter motor.

[0058] Specifically, the fourth fixing holes 14 and the sixth fixing holes 25 are in corresponding positions. Through these holes, the electrical controller can be directly fixed between the inner door panel 200 and the waterproof film 10, ensuring the stability of the electrical controller during vehicle driving, and reducing the risk of displacement or damage caused by vibration or collision. The fifth fixing holes 15 and the seventh fixing holes 26 are in corresponding positions, which are used to accurately fix the door glass lifter motor, ensuring the stable position of the motor during door opening and closing and vehicle driving, and avoiding the functional failure or increased noise caused by the movement or loosening of the motor. Fixing the electrical controller and the door glass lifter motor through the preset hole positions simplifies the assembly steps and improves the assembly efficiency. When maintenance or replacement of the electrical controller or the lifter motor is required, it can be quickly located and easily disassembled, reducing the maintenance cost and time consumption, and improving the maintainability of the door sealing structure and the electrical system.

[0059] Combined with Figure 3 、 Figure 4 、 Figure 7 、 Figure 9As shown, the waterproof film 10 further includes a first wire harness through-hole 16. The first wire harness through-hole 16 is disposed at one side corner of the film body 12. The connecting plate 20 further includes a second wire harness through-hole 27. The second wire harness through-hole 27 is disposed corresponding to the position of the first wire harness through-hole 16. The second wire harness through-hole 27 and the first wire harness through-hole 16 are used for an electrical wire harness to pass through. The door sealing device further includes: a wire harness through-hole sealing film 40. The wire harness through-hole sealing film 40 is connected to the connecting plate 20. A third wire harness through-hole 41 is provided on the wire harness through-hole sealing film 40. The third wire harness through-hole 41 is disposed corresponding to the positions of the second wire harness through-hole 27 and the first wire harness through-hole 16. The wire harness through-hole sealing film 40 is used for the electrical wire harness to pass through the third wire harness through-hole 41 and surround and connect the electrical wire harness.

[0060] Specifically, by respectively providing the first wire harness through-hole 16 on the waterproof film 10 and the second wire harness through-hole 27 on the connecting plate 20, and adding the third wire harness through-hole 41 on the wire harness through-hole sealing film 40, a complete wire harness waterproof sealing system is formed. When the electrical wire harness passes through these through-holes, the wire harness through-hole sealing film 40 closely adheres to the wire harness, effectively preventing moisture from penetrating into the door cavity along the wire harness, and further improving the overall waterproof performance of the door. The corresponding setting of the first wire harness through-hole 16 and the second wire harness through-hole 27, and the precise matching of the third wire harness through-hole 41 ensure the accurate positioning of the electrical wire harness during the passing process, reduce the assembly deviation, and simplify the assembly process. Workers only need to pass the wire harness through the corresponding through-holes and then wrap it with the wire harness through-hole sealing film 40. The assembly is fast and easy to operate, improving the overall efficiency of the production line.

[0061] In one embodiment, the connecting plate 20 further includes a plurality of single wire harness through-holes 28. The plurality of single wire harness through-holes 28 are disposed at a distance from the second wire harness through-hole 27. Each single wire harness through-hole 28 is used for a single wire harness to pass through.

[0062] Combined Figure 7 、 Figure 8 As shown, an arc-shaped mating surface 42 is provided on the wire harness through-hole sealing film 40. The arc-shaped mating surface 42 is mated and connected with the connecting plate 20. The wire harness through-hole sealing film 40 is made of at least one of non-woven fabric, butyl film, release paper, and separation sticker.

[0063] Specifically, the wire harness through-hole sealing film 40 includes: a first part 43, a second part 44, and a third part 45 to meet the bonding requirements at different workstations. Among them, the first part 43 is provided with the arc-shaped mating surface 42 to cooperate with the protruding structure on the connecting plate 20. The second part 44 and the third part 45 are located above the first part 43, and the second part 44 and the third part 45 are adjacent to each other. Among them, at least part of the second part 44 and at least part of the third part 45 are provided with separation stickers 46.

[0064] In this embodiment, the first part 43, the second part 44, and the third part 45 are all quadrilateral structures. In other embodiments, they can be set as circular or polygonal structures, and the shape is not limited.

[0065] The operation process of this device is as follows: First, at the offline sub-assembly station, first tear off the release paper on the isolation paper of the sealing strip 30, and bond it around the receiving groove 21 of the connecting plate 20 in a full circle. Then, tear off the release paper of the film 13 on the waterproof film 10 and bond it to the connecting plate 20. As Figure 10 shown, the waterproof film 10 and the sealing strip 30 are on the same side of the connecting plate 20; then at the same station, uncover the release paper of the first part 43 of the above-mentioned wire harness through-hole sealing film 40, and bond it to the corresponding arc on the other side of the connecting plate 20 by using the arc-shaped mating surface 42. When the electrical wire harness passes through the first wire harness through-hole 16, the second wire harness through-hole 27, and the third wire harness through-hole 41, uncover the release paper of the second part 44 and the third part 45 of the above-mentioned wire harness through-hole sealing film 40, and tightly hoop the electrical wire harness. The third wire harness through-hole 41 of the electrical wire harness and the above-mentioned wire harness through-hole sealing film 40 is an interference fit to ensure that rainwater does not leak from here during the rain.

[0066] According to another aspect of the present invention, a vehicle is provided, including a door sealing device, and the door sealing device is the door sealing device of the above embodiment. The door sealing device includes: a waterproof film 10, one side of the waterproof film 10 is used to connect with the inner door panel 200; a connecting plate 20, the connecting plate 20 is connected to the other side of the waterproof film 10, and the connecting plate 20 is connected to the inner door panel 200; a sealing strip 30, the sealing strip 30 is located between the waterproof film 10 and the connecting plate 20, and the sealing strip 30 is arranged along the circumference of the connecting plate 20.

[0067] In this embodiment, a preliminary waterproof structure is established by directly connecting the waterproof membrane 10 with the door inner panel 200. On this basis, a connecting plate 20 is connected to the other side of the waterproof membrane 10, and the connecting plate 20 is also connected to the door inner panel 200, so that the double stability of the door sealing device in structure is achieved, ensuring the integrity and durability of the sealing structure, especially when the vehicle encounters vibration or impact during driving, it can maintain a good sealing state. By setting a sealing strip 30 between the waterproof membrane 10 and the connecting plate 20, the sealing strip 30 is arranged along the circumference of the connecting plate 20. The configuration utilizes the compression deformation of the sealing strip 30 when under pressure and the high rebound characteristics after pressure release, so that when the connecting plate 20 is connected to the door inner panel 200, the waterproof membrane 10 fits tightly around the door inner panel 200 under the push of the elastic reaction force of the sealing strip 30 itself, thereby achieving the technical effect of effectively preventing rain from splashing into the interior during rain, and solving the technical problems in the traditional door sealing structure, such as poor waterproof effect and moisture or even damage to the interior due to deformation of the sealing strip during assembly, uneven assembly or performance degradation after long-term use.

[0068] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0069] (1) While improving the waterproof sealing performance, since the door sealing device is fixed as a whole on the inner door panel, it is convenient to disassemble it for subsequent vehicle maintenance. At the same time, since the sealing strip has a highly elastic EPDM foam sandwich, there is no need to consider the problem of local deformation caused by the assembly or transportation of the strip, which may lead to leakage. The requirements on the personal ability, experience and operation consistency of the operator are not high, and the fault tolerance rate is high.

[0070] (2) The harness through-hole sealing adhesive film is composed of non-woven fabric, butyl film, release paper and separation sticker. The release paper is divided into three parts and peeled off and bonded to the metal inner plate at different workstations. It can be assembled at different workstations to improve production rhythm and meet the needs of workers' convenience in operation.

[0071] (3) The sealing structure not only ensures waterproofness, but also provides fixing points for surrounding environmental parts, such as the door glass lifter motor, electrical controller, and door interior buckle.
