Description

Technical Field

[0001] This application relates to the field of vehicle door sealing technology, and more specifically, to an inward-opening vehicle door and a vehicle. Background Technology

[0002] Most existing traditional car doors are outward-opening doors, which require a large amount of space outside the vehicle when opened. When the vehicle is in a narrow space, opening the door outward can easily cause collisions and pose a safety hazard. If the door could open inward, it would be easier to open the door in a narrow space.

[0003] Traditional outward-opening car doors have relatively complete sealing surfaces, making the sealing structure relatively simple. However, inward-opening car doors lack sealing surfaces and have directly exposed parts, making it more difficult to seal and waterproof them.

[0004] In conclusion, how to seal inward-opening car doors is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of this application is to provide an inward-opening vehicle door and a vehicle for sealing the inward-opening vehicle door.

[0019] In some embodiments, the outer water-cutting angle is provided with a first hydrophobic lip and an outer water-cutting drain hole; the first hydrophobic lip is used to guide water flow to the bottom of the door body, and the outer water-cutting drain hole is used to guide water flow into the inner cavity of the door body and discharge it through the door drain hole.

[0020] In some embodiments, the upper groove is formed by an upper groove body and upper groove corners located at both ends of the upper groove body; the upper groove corners are provided with a second hydrophobic lip and a third hydrophobic lip, the second hydrophobic lip and the third hydrophobic lip being used to guide water flow into the inner cavity of the door body and discharge it through the door drain hole.

[0021] A vehicle including, as described above, an inward-opening door.

[0022] The inward-opening door provided in this application can open inward relative to the vehicle body. The vehicle body has a body stop around the door opening and a body guide rail located at the upper edge of the door opening. The inward-opening door includes a door body, a window glass that slides with the door body, and a sealing system. Its sealing system includes a door frame strip, a split-type groove, and a water-cutting component. The door frame strip is snapped into the body stop and is formed by an upper connecting section, a lower connecting section, and two connecting corners.

[0057] like Figures 1-6 As shown, the inward-opening car door provided in this application embodiment can be opened inward relative to the car body 100. The car body 100 has a car body stop 110 surrounding the door opening and a car body guide rail 120 located at the upper edge of the door opening. The inward-opening car door includes a door body 200, a window glass 300 that slides with the door body 200, and a sealing system.

[0058] like Figure 1 As shown, the sealing system includes a door frame strip 410, a split-type groove, and a water-cutting assembly.

[0059] like Figure 2As shown, the door frame strip 410 is snapped onto the body stop 110. The door frame strip 410 is formed by an upper connecting section 411, a lower connecting section 412, and two connecting corners 413. The two connecting corners 413 correspond to the waistlines on both sides of the door body 200, so that the door frame strip 410 can press against and adhere to the inner panel surface of the door body 200 when the door is closed, thereby achieving a circumferential seal of the lower half of the door body 200. The upper connecting section 411 is located in the area of ​​the body stop 110 corresponding to the window glass 300. When the window glass 300 is raised to the closed position, the upper connecting section 411 can press against and adhere to the side of the window glass 300.

[0060] like Figure 1 , Figure 4 , Figures 9-10 As shown, the split-type felt channel includes an upper felt channel 510 and side felt channels 520. The upper felt channel 510 is installed inside the body guide rail 120 and is used to seal the upper edge of the window glass 300 when the window glass 300 is raised to the closed position. It also cooperates with the connecting section 411 to seal the side of the window glass 300, thereby achieving a seal on the window glass 300. There are two side felt channels 520, which are respectively installed in the inner cavity guide rail of the door body 200. The side felt channels 520 are used to guide the sliding and lifting of the window glass 300, so that the window glass 300 can be raised and lowered relative to the door body 200 through the side felt channels 520. The upper felt channel 510... The side groove 520 and the upper groove 510 are independent of each other and there is no connection between them. When the door opens inward, the side groove 520 moves together with the door body 200, while the upper groove 510 remains stationary. There is no connection, interference, or friction and wear between them, which solves the problem that traditional one-piece grooves cannot be used normally on inward-opening doors due to inconsistent movement trajectories. This ensures the smoothness of the window glass 300 raising and lowering and the normal opening and closing of the door.

[0061] like Figure 1 , Figures 5-6 As shown, the water-cutting assembly includes an inner water-cutter 610 and an outer water-cutter 620. The inner water-cutter 610 and the outer water-cutter 620 are respectively installed at the inner and outer stops of the door body 200. Due to the step difference between the sealing surfaces of the door frame strips 410 on both sides of the waistline of the door body 200, the connecting corner 413 has a discontinuous sealing surface at the stop of the door body 200. The outer water-cutter 620 of this application includes an outer water-cutting body 621 and an outer water-cutting corner 622 connected to both ends of the outer water-cutting body 621. When the door is closed, the outer water-cutting corner 622 can press and seal with the connecting corner 413, so that the outer water-cutting corner 622 acts as a sealing base, providing a continuous sealing surface for the door frame strip 410 at the waistline corner, so as to ensure the sealing effect.

[0062] Through the coordinated operation of the aforementioned door frame strip 410, split-type groove, and water-cutting assembly, a complete sealing system adapted to the movement characteristics and structural features of inward-opening vehicle doors is constructed. Each component has a clear division of labor yet interconnects, forming a continuous sealing chain from the lower half of the door body 200, through the waistline corner area, to the upper half of the window glass 300 area when the door is closed. When the door is open, there is no interference or pulling between the components, balancing the freedom of movement and sealing reliability of the inward-opening vehicle door.

[0063] Since the sealing effect of the door body 200 is mainly achieved by the lower connecting section 412 of the door frame strip 410, in order to further ensure the sealing effect of the door body 200, such as Figures 7-8 As shown, a first water-blocking lip 4121 and a second water-blocking lip 4122 are provided on the lower connecting section 412. The first water-blocking lip 4121 protrudes from the body stop 110 toward the door body 200, so that the first water-blocking lip 4121 can deform and fit tightly with the door body to form the first waterproof barrier facing the door side, which directly blocks most of the water flowing down the inner panel of the door from the sealed core area.

[0064] The second water-blocking lip 4122 protrudes toward the body stop 110 so that the second water-blocking lip 4122 can deform and fit tightly and seal with the body stop 110, forming a second waterproof barrier facing the body side, preventing water from seeping in from the body stop 110 side.

[0065] Among them, such as Figure 8 As shown, the first water-blocking lip 4121 has a double-bubble structure, consisting of two parallel hollow bubble tubes forming a sealing contact surface with the door body 200, significantly improving sealing stability and fault tolerance. Furthermore, at the bottom corner of the door body 200, where water flows along both sides of the door and converges at the bottom, there is a significant amount of water accumulation in this area. A sponge tube 4123 can be filled inside one of the hollow bubble tubes in the first water-blocking lip 4121 of the double-bubble structure. The rebound support of the sponge tube 4123 can effectively enhance the sealing force of the bubble tube, preventing the bubble tube from being crushed and the seal from failing due to high water pressure. At the same time, the elastic compensation capability of the sponge tube 4123 allows the sealing structure at this location to accommodate changes in sealing gaps caused by manufacturing tolerances or long-term use, improving assembly robustness and durability.

[0066] like Figure 8 As shown, a sealant 4124 is provided at the root position where the lower connecting section 412 engages with the body stop 110. When the second water-blocking lip 4122 weakens due to aging from long-term use, reduced deformation recovery ability, or extreme water accumulation, the sealant 4124 can prevent a small amount of water flowing past the second water-blocking lip 4122 from continuing to seep into the interior of the vehicle along the body stop 110, further improving the overall reliability of the sealing system.

[0067] Since the sealing of the car window glass 300 is mainly accomplished simultaneously by the upper connecting section 411 and the upper groove 510, in order to further improve the sealing effect of the car window glass 300, such as Figures 9-10 As shown, the upper groove 510 is provided with a third water-blocking lip 5101 protruding towards the vehicle body guide rail 120, so that the third water-blocking lip 5101 can fit tightly against the inner wall of the vehicle body guide rail 120, blocking the water flow that may seep in along the vehicle body guide rail 120 to the outside of the upper groove 510; the upper groove 510 is also provided with a fourth water-blocking lip 5102, which protrudes towards the window glass 300 and can fit and seal against the side of the window glass 300 when the window glass 300 is raised to the closed position, so as to seal the gap between the window glass 300 and the upper groove 510, so that the upper groove 510 achieves double waterproofing capability and provides a reliable seal for the upper edge of the window glass 300.

[0068] like Figure 10 As shown, the upper connecting section 411 is provided with a fifth water-blocking lip 4111. The fifth water-blocking lip 4111 protrudes from the body stop 110 toward the window glass 300, and the fifth water-blocking lip 4111 can deform and fit tightly and seal with the window glass 300. In this way, the sealing of the window glass 300 is jointly undertaken by the fifth water-blocking lip 4111 of the upper connecting section 411 and the fourth water-blocking lip 5102 of the upper groove 510. The two form a double sealing protection for the window glass 300 from the inner and outer sides and different positions above and below, respectively, which significantly improves the sealing effect.

[0069] Among them, the fifth water-blocking lip 4111 is an irregular single-bubble structure, that is, the cross-sectional shape of its bubble tube is designed to match the curvature and tilt angle of the window glass 300 and the spatial shape of the body stop 110 in this area. It can fit the side of the window glass 300 in the best posture in a limited and irregular installation space, ensuring that the bubble tube forms a uniform and sufficient contact pressure distribution with the glass after compression, avoiding the problem of bubble tube twisting or insufficient fitting due to space limitations.

[0070] The sealing of both sides of the waistline of the door body 200 is mainly achieved through the cooperation of the connecting corner 413 of the door frame strip 410 and the outer water-cutting corner 622, such as Figures 11-12 As shown, the connecting angle 413 has a bottom sealing surface, and the connecting angle 413 is sealed to the outer water-cutting angle 622 through the bottom sealing surface.

[0071] like Figure 12As shown, a sixth water-blocking lip 4131 is provided on the bottom sealing surface of the connecting corner 413. The sixth water-blocking lip 4131 protrudes outward from the water-cutting edge 620 and deforms when the door is closed, tightly fitting and sealing with the water-cutting edge 620. The sixth water-blocking lip 4131 forms an additional line seal on the mating surface of the connecting corner 413 and the water-cutting edge 622, effectively preventing water from seeping in between the mating surfaces, significantly improving the waterproof reliability and durability of the weak sealing link, the waistline corner.

[0072] Because water flows from both sides of the door body 200 to the bottom, a water accumulation area is formed at the bottom of the door body 200, which requires drainage treatment.

[0073] like Figures 13-15 As shown, the lower connecting section 412 is also provided with a cloak structure that cooperates with the door trim panel 130. The cloak structure is only retained in the two side areas of the lower connecting section 412, and the area at the bottom of the lower connecting section 412 is removed. At the same time, the structure at the bottom of the door trim panel 130 that cooperates with the lower connecting section 412 only retains the two side areas and removes the bottom area. This ensures that the water flowing down from the two sides of the door will not be caught by the cloak structure and misled to the bubble tube sealing area of ​​the door frame strip 410. Instead, it will smoothly flow directly into the bottom of the car body along the inner wall of the trim panel. This avoids the retention and accumulation of water in the sealing core area from the source and reduces the waterproof burden on the bottom sealing structure of the lower connecting section 412.

[0074] like Figure 18 As shown, at the corner of the lower connecting section 412, a portion of the second water-retaining lip 4122 that was intended to fit against the vehicle body 100 is removed. While the second water-retaining lip 4122 primarily serves to prevent water from seeping in from the vehicle body stop 110, maintaining the complete second water-retaining lip 4122 at the bottom corner area could trap water that has already crossed the outer barrier inside the sealing system. By partially removing the second water-retaining lip 4122 in this area, a directional drainage channel is opened, allowing water entering the corner area to be directed to the bottom of the vehicle body, thus achieving drainage.

[0075] like Figures 16-17 As shown, a door drain hole 210 is provided at the bottom of the door body 200, and the door drain hole 210 is higher than the first water-blocking lip 4121 and the second water-blocking lip 4122. When the water at the bottom reaches a certain level and exceeds the blocking threshold of the water-blocking lip, the water can flow through the door drain hole 210 into the inner cavity of the door body 200, preventing the water from crossing the water-blocking lip and entering the sealing core area.

[0076] like Figure 14As shown, a drainage hole 140 is provided at the bottom of the vehicle body 100 to discharge the water flow introduced into the bottom of the vehicle body to the outside of the vehicle, forming a complete water flow discharge terminal channel and avoiding water flow from accumulating at the bottom of the vehicle body for a long time.

[0077] like Figure 19 As shown, the outer water cut-off angle 622 is provided with a first hydrophobic lip 6221 and an outer water cut-off drain hole 6222, so that the water flow is guided to the bottom of the door body 200 through the first hydrophobic lip 6221, and the outer water cut-off drain hole 6222 guides the water flow into the inner cavity of the door body 200. The two are then discharged to the outside of the vehicle through the door drain hole 210 and the car body drain hole 140, respectively.

[0078] like Figure 20 As shown, the upper groove 510 is formed by the upper groove body 511 and the upper groove corners 512 located at both ends of the upper groove body 511.

[0079] The upper groove corner 512 is provided with a second hydrophobic lip 5121 and a third hydrophobic lip 5122, which respectively direct the water flowing down the glass surface on both sides of the window glass 300 to the inner cavity of the door body 200, and then discharge it to the outside of the vehicle through the door drain hole 210.

[0080] The inward-opening vehicle door provided in this application embodiment has a sealing system that, through the coordinated operation of the aforementioned door frame strip 410, split-type groove, and water-cutting assembly, constructs a complete sealing system adapted to the movement characteristics and structural features of the inward-opening vehicle door. Each component has a clear division of labor yet is interconnected, forming a continuous sealing chain from the lower half of the door body 200, through the waistline corner area, to the upper half of the window glass 300 area when the door is closed. When the door is open, there is no interference or pulling between the components, balancing the freedom of movement and sealing reliability of the inward-opening vehicle door.

[0081] This application also provides a vehicle that includes the inward-opening door described in the above embodiments.

[0082] Since the aforementioned inward-opening door has the aforementioned technical effects, and the aforementioned vehicle includes the aforementioned inward-opening door, the aforementioned vehicle also has the corresponding technical effects, which will not be elaborated here.

[0083] The above description of the embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
