Description

Technical Field

[0001] This application relates to the field of frameless car door technology, and in particular to a car door sealing assembly and a vehicle. Background Technology

[0002] Frameless car door models in related technologies generally feature an independent glass short-sliding system (an independent opening and closing system or independent opening and closing mechanism for frameless doors), specifically including motors or linkage mechanisms. When the door is opened, the glass short-sliding system is activated, lowering the door glass by 5mm to 30mm in a short time, thus detaching it from the compressed and accumulated sealing strip and ensuring that the door opening is not interfered with. When the door is closed, the door glass rises, compressing the sealing strip and causing it to cover the door glass, thus ensuring a tight seal. Compared to framed door models, the sealing performance of frameless doors is lower than that of framed doors. Summary of the Invention

Detailed Implementation

[0034] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0035] See Figure 1 This application provides an embodiment of a vehicle, which includes a body, frameless doors, and glass 10. The frameless doors are detachably mounted on the vehicle body, and the opening method is, for example, to open by rotation or by sliding along the front-rear direction of the vehicle body. The number of frameless doors includes, but is not limited to, one, two, three, four, or more. For example, four frameless doors are provided: a left front door, a right front door, a left rear door, and a right rear door. Glass 10 is mounted on the frameless doors. The number of glass 10 is the same as the number of frameless doors.

[0036] Generally, frameless doors have lower sealing performance than framed doors. To improve the sealing performance of frameless doors when closed, for example, the vehicle also includes a door sealing assembly. The vehicle body includes a side panel 30, and the door sealing assembly is fixedly mounted on the side panel 30. The door sealing assembly specifically engages with the glass 10 in a sealing contact, providing a better sealing effect when the door is closed, thus serving functions such as sound insulation and waterproofing.

[0037] Please see Figures 1 to 3 For example, the door sealing assembly includes a side trim strip 21 and a sealing strip 22. The side trim strip 21 is mounted on the side sheet metal 30. The sealing strip 22 is connected to the side trim strip 21.

[0038] Please see Figure 2 and Figure 3 The sealing strip 22 includes a sealing portion 222 for sealing and abutting with the glass 10, and a first sealing structure 2228 connected to the sealing portion 222. The first sealing structure 2228 is used for sealing and abutting with the inner surface 12 of the glass 10, and the first sealing structure 2228 is provided with at least two teeth 22281. Each tooth 22281 extends along the length direction of the sealing strip 22, and at least two teeth 22281 are arranged sequentially at intervals along the lifting direction of the glass 10. When the glass 10 is in the closed position, at least two teeth 22281 seal and abut with the inner surface 12 of the glass 10.

[0039] The aforementioned door sealing assembly and vehicle, on the one hand, when the glass 10 is in the closed position, the top end face 13 of the glass 10 presses against the sealing part 222, causing the sealing part 222 to deform to form a pressure seal against the top end face 13 of the glass 10. Furthermore, the first sealing structure 2228 seals against the inner side surface 12 of the glass 10 through at least two teeth 22281, forming at least two seals, thereby ensuring good sealing performance after the glass 10 is closed. On the other hand, the first sealing structure 2228, which plays a sealing role, is interconnected with the sealing part 222, facilitating disassembly and assembly operations.

[0040] Please see Figure 2 and Figure 3 For example, the first sealing structure 2228 includes a sealing skirt. The top of the sealing skirt is connected to the sealing portion 222, and the bottom of the sealing skirt seals against the inner surface 12 of the glass 10. At least two teeth 22281 are specifically provided, for example, at the bottom of the sealing plate. The sealing skirt extends along the length of the sealing strip 22, for example, from one end of the sealing strip 22 along the length direction to the other end of the sealing strip 22 along the length direction. The teeth 22281 extend along the length direction of the sealing strip 22. The teeth 22281 extend from one end of the sealing strip 22 to the other end of the sealing strip 22.

[0041] For example, the sealing portion 222 and the first sealing structure 2228 are integrally molded, for example, by injection molding.

[0042] For example, the sealing strip 22 also includes a second sealing structure 2226. The second sealing structure 2226 is connected to the sealing part 222, and is spaced apart from the first sealing structure 2228. The second sealing structure 2226 is used to seal and abut against the top end face 13 or the outer side face 11 of the glass 10. Thus, when the glass 10 is in the closed position, the second sealing structure 2226 seals and abuts against the glass 10, further improving the sealing performance. Furthermore, the first sealing structure 2228, the sealing part 222, and the second sealing structure 2226 can support the glass 10, effectively suppressing the shaking generated during vehicle operation and further reducing driving noise.

[0043] The sealing strip 22 has a natural state and a compressed state and can switch between the two states.

[0044] Specifically, when the glass 10 is raised and the sealing part 222 is compressed, that is, when the sealing strip 22 is in a compressed state, the sealing part 222 tightly abuts against the top end face 13 of the glass 10 to cover the top end face 13 of the glass 10. The first sealing structure 2228 abuts against and is positioned against the inner side surface 12 of the glass 10, and the second sealing structure 2226 bends toward the glass 10 and seals against the glass 10, thereby improving the sealing performance and providing better sound insulation, dustproofing, and waterproofing. Furthermore, when the first sealing structure 2228 abuts against and is positioned against the inner side surface 12 of the glass 10, based on the leverage effect, while the sealing part 222 is compressed and deformed, the free end of the first sealing structure 2228 moves toward the inner side surface supporting the glass 10 and abuts against the inner side surface supporting the glass 10, playing a role in stably supporting the inner side surface 12 of the glass 10 and ensuring good sealing performance.

[0045] Specifically, the second sealing structure 2226 can either abut against the top end face 13 of the glass 10 or abut against the outer side face 11 of the glass 10. In this embodiment, the second sealing structure 2226 preferably abuts against the top end face 13 of the glass 10, so that the glass 10 can be opened smoothly when it is opened outward, and can also be closed smoothly, avoiding interference and jamming during the opening and closing process.

[0046] Wherein, the outer side 11 of the glass 10 refers to the side of the glass 10 facing the external environment of the vehicle; the inner side 12 of the glass 10 refers to the side of the glass 10 facing away from the external environment of the vehicle; and the top end face 13 of the glass 10 refers to the part of the glass 10 that connects the outer side 11 and the inner side 12 of the glass 10.

[0047] Please see Figure 2 , Figure 3 , Figure 5 and Figure 6 For example, the second sealing structure 2226 includes a support arm 22261 and an abutment arm 22262. The top of the support arm 22261 is connected to the sealing portion 222, and the abutment arm 22262 is connected to the bottom of the support arm 22261, and the abutment arm 22262 is set at an angle to the support arm 22261. The abutment arm 22262 is used to abut against the glass 10. Thus, when the glass 10 presses against the sealing portion 222, the sealing portion 222 deforms and abuts tightly against the top end face 13 of the glass 10, while the abutment arm 22262 moves toward the glass 10 and abuts tightly against the glass 10. Since the abutment arm 22262 is set at an angle to the support arm 22261, it can play a buffering role, thereby ensuring the sealing performance.

[0048] For example, the side trim strip 21 includes an outer panel 211. The bottom of the outer panel 211 has a first flange 2113 that bends towards the second sealing structure 2226. When the glass 10 is in the closed position, i.e., when the sealing strip 22 is in a compressed state, the end of the first flange 2113 abuts against the second sealing structure 2226. Thus, the first flange 2113 supports the second sealing structure 2226, not only improving the sealing line but also effectively suppressing shaking generated during vehicle operation, further reducing driving noise.

[0049] Please see Figures 1 to 3 For example, when the sealing strip 22 is in its natural state, that is, when the glass 10 is in the closed position, the bottom of the outer panel 211 and the top of the glass 10 have a clearance gap in the vertical direction. The clearance gap is as follows: Figure 1 The position indicated by the spacing D in the diagram.

[0050] It should be noted that the vertical direction refers to the direction perpendicular to the horizontal ground, with the vehicle normally placed on the horizontal ground as a reference, that is, the up and down direction.

[0051] To ensure the frameless doors open smoothly, the calculation of the gap between the glass 10 and the side trim strip 21 must take into account the actual and theoretical deviations. Please refer to [link / reference needed]. Figure 1The vertical distance between the bottom of the outer side panel 211 and the glass 10 raised to the top is set as D. The vertical deviation of the glass 10 when it is raised to the top is set as A, and the deviation along the lifting trajectory when the glass 10 is raised to the top is set as B. The deviation along the lifting trajectory when the glass 10 is raised to the top refers to the difference between the actual value and the target value along the lifting trajectory when the glass 10 is raised to the top. The angle between the lifting trajectory of the glass 10 and the vertical direction is set as β, and the safety margin is set as C. The safety margin C can be flexibly adjusted and set according to factors including but not limited to assembly deviations and the surface tolerance of the side trim strip 21. The specific size is not limited here. According to the trigonometric function relationship, A=B*Sinβ. Therefore, D>B*Sinβ+C. In this way, by satisfying this condition, it can be ensured that there is no interference between the glass 10 and the side trim strip 21, thereby ensuring that the door opens smoothly.

[0052] For example, the sealing strip 22 also includes a mounting part 221, which is installed inside the side panel trim strip 21. The mounting part 221 is connected to the sealing part 222, and the mounting part 221 and the sealing part 222 enclose a non-closed chamber 223. The opening 224 of the non-closed chamber 223 is close to the outer side panel 211.

[0053] Please see Figures 4 to 6 Specifically, when the glass 10 is in the open position, the top of the glass 10 is separated from the sealing part 222, the sealing part 222 is engaged with the bottom of the outer side plate 211, and a non-closed cavity 223 is formed between the sealing part 222 and the mounting part 221. The non-closed cavity 223 provides deformation space, and the sealing strip 22 is easy to elastically deform when subjected to the compressive force of the glass 10.

[0054] Please see Figures 1 to 3 When the sealing strip 22 is in a compressed state and the glass 10 is in a closed position, the non-closed chamber 223 is used to accommodate the deformation of the sealing part 222 to form a pressure seal on the glass 10, and the bottom of the outer plate 211 and the top of the glass 10 are provided with a clearance gap in the vertical direction.

[0055] In summary, on the one hand, when the sealing strip 22 is in its natural state, that is, when the glass 10 is in the closed position, the bottom of the outer panel 211 and the top of the glass 10 have a clearance gap in the vertical direction, so that during the opening and closing of the door, the top of the glass 10 will not be interfered with by the outer panel 211 without lowering or adjusting its height, thus avoiding rigid obstruction. When the door is powered off, it can be opened normally under external force, improving safety. Moreover, compared with the method of forcibly opening the door, it can greatly reduce the damage to the sealing strip 22, which is conducive to long-term normal use. On the other hand, the non-enclosed chamber is used to accommodate the deformation of the sealing part 222 to form a pressure seal on the glass 10, thereby ensuring the sealing performance and reliability of the glass 10 after it is closed. In addition, when the glass 10 is in the open position, the sealing part 222 and the bottom of the outer panel 211 are interlocked, and the outer panel 211 supports the sealing part 222, preventing the sealing part 222 from falling downward and causing the door to be unable to open and close normally.

[0056] Since the sealing part 222 is interlocked with the bottom of the outer panel 211, it not only ensures the overall stability of the sealing strip 22, but also reduces its detachment rate during opening and closing, thereby effectively preventing the sealing strip 22 from falling off during vehicle operation or when the glass 10 is raised or lowered.

[0057] In addition, since the mounting part 221 and the sealing part 222 enclose a non-closed chamber 223, the opening 224 of the non-closed chamber 223 is located outside the sealing strip 22. That is, the sealing strip 22 adopts a semi-open structure. Compared with the closed structure, when the glass 10 is switched to the open position, the sealing part 222 is easier to restore to its original state, so that the door can be opened and closed smoothly and can be used normally for a long time.

[0058] Please see Figures 1 to 3 When the sealing strip is in a compressed state, i.e., the frameless door is in the closed position, during the process of the glass 10 rising to the top, the direction of the glass 10's rise and fall is, for example... Figure 1 As shown by the double arrow S, the glass 10 first comes into contact with the sealing part 222, and then the sealing part 222 is squeezed and pushed up, so that the sealing part 222 enters the non-enclosed chamber and comes into contact with and is fixed to the mounting part 221. Under the obstruction of the mounting part 221 and further compression, the sealing part 222 deforms and finally tightly covers the glass 10, realizing the functions of sealing and buffering.

[0059] When glass 10 is at the top, switching the frameless door from open to closed, that is, when the frameless door is, for example, from... Figure 4 Switch to the position shown. Figure 1 The frameless door moves in the direction shown in the image. Figure 1As indicated by the double arrow K, when the glass 10 contacts the sealing part 222, it will compress and push up the sealing part 222, causing the sealing part 222 to enter the non-enclosed chamber 223 and abut against and be fixed to the mounting part 221. Under the obstruction and further compression of the mounting part 221, the sealing part 222 deforms and finally tightly covers the glass 10, achieving the functions of sealing and buffering.

[0060] Conversely, when the frameless door is in the closed position and the glass 10 is at the top, during the process of switching the frameless door from closed to open, that is, the frameless door, for example, from... Figure 1 Switch to the position shown. Figure 4 At the position shown, the sealing part 222 returns to its original shape under its own elastic force and engages with the bottom of the outer side plate 211. The outer side plate 211 supports the sealing part 222 and prevents the sealing part 222 from falling down and causing the door to be unable to open and close normally.

[0061] As can be seen, the frameless door in this application differs from frameless doors in that it does not require the glass 10 to be lowered by 5mm to 30mm when opening or closing. Because the bottom of the outer side panel 211 of the side trim strip 21 is higher than the top of the glass 10 in its raised state, and there is a clearance between them, the side trim strip 21 does not interfere with the door opening and closing process, thus avoiding rigid obstruction. Even if the glass 10 is not lowered during the opening of the frameless door, the frameless door can still be opened smoothly, and no parts of the vehicle will be damaged. Furthermore, the sealing strip 22 will not fall off during the opening and closing process and can effectively perform its sealing function.

[0062] In addition, the side decorative strip 21 can not only effectively protect the sealing strip 22 from daily wind, sun and rain erosion, thus ensuring stable sealing performance, but also assist in guiding the deformation of the sealing strip 22.

[0063] Building upon the aforementioned embodiments, the frameless door in this embodiment eliminates the glass 10 short-sliding system. Even in extreme situations such as a power outage, the frameless door can be opened smoothly without lowering the glass 10. This improvement not only aligns with lightweight design principles, reducing vehicle weight and thus enhancing safety, but also effectively reduces manufacturing costs. Furthermore, the door's sealing and sound insulation performance are significantly improved, achieving a dual optimization of lightweighting and sealing performance, further enhancing the driving experience.

[0064] For example, the opening 224 is provided to extend along the length of the sealing strip 22, from one end of the sealing strip 22 along its length to the other end of the sealing strip 22 along its length.

[0065] For example, the sealing part 222 has a first end 2221 along its width direction connected to the mounting part 221, and the second end 2222 along its width direction is a free end. The free end engages with the bottom of the outer side plate 211.

[0066] Wherein, the width direction of the sealing part 222 is as follows Figure 1 The direction indicated by the double arrow W in the diagram.

[0067] Specifically, when the glass 10 is in the open position, the free end engages with the bottom of the outer panel 211; when the glass 10 is in the closed position, the free end moves toward the mounting part 221 and abuts against the mounting part 221.

[0068] The free end is not directly connected to the mounting part 221, so that it can move toward the mounting part 221 when the glass 10 is squeezed, and return to its original shape under the action of its own elastic force when the glass 10 is released.

[0069] In one embodiment, the forming process of the side decorative strip 21 mainly involves extrusion, bending, and milling, and the material used is, for example, mainstream 6-series aluminum alloy. This results in good mechanical properties, light weight, and high strength.

[0070] In one embodiment, the hardness of the mounting portion 221 is greater than that of the sealing portion 222. Thus, the greater hardness of the mounting portion 221 allows it to be stably installed within the side panel trim strip 21; while the lower hardness of the sealing portion 222 makes it more susceptible to deformation under stress, thereby ensuring a tight seal and facilitating restoration to its original shape.

[0071] To ensure the processing quality and efficiency of the sealing strip 22, the mounting part 221 and the sealing part 222 are integrally molded using a two-material co-extrusion process, for example. Optionally, the sealing strip 22 is co-extruded from ethylene propylene diene monomer (EPDM) rubber or other elastic materials. The mounting part 221 is made of dense EPDM rubber, i.e., a non-foamed material, which provides greater hardness and higher installation stability within the side decorative strip 21. The sealing part 222 is made of sponge EPDM rubber, i.e., a foamed material, which provides lower hardness, allowing for easy elastic deformation under external force and easy restoration of its original shape when the glass 10 is switched to the open position.

[0072] For example, the mounting part 221 may be installed within the side trim strip 21 by snap-fitting, bonding, welding, or other methods. It may also be fixedly connected to the side trim strip 21 using fasteners such as pins, screws, or rivets. In this embodiment, to improve the efficiency of mounting and disassembling the mounting part 221, the mounting part 221 is specifically installed within the side trim strip 21 by snap-fitting, for example.

[0073] Please see Figure 2 and Figure 3 For example, the side trim strip 21 also includes an inner side panel 212 and a connecting plate 213. The inner side panel 212 is connected to the outer side panel 211 via the connecting plate 213. The inner side panel 212, the connecting plate 213, and the outer side panel 211 enclose a mounting chamber 214. A mounting opening 215 is formed at a distance between the bottom of the inner side panel 212 and the bottom of the outer side panel 211. The mounting opening 215 communicates with the mounting chamber 214. The mounting part 221 is snapped into the mounting chamber 214, and a sealing part 222 is provided at the mounting opening 215. The sealing part 222 is located below the mounting part 221 and is exposed through the mounting opening 215. When the frameless door is in the closed position, during the process of the glass 10 rising to the top, the direction of the glass 10's rise and fall is, for example... Figure 1 As shown by the double arrow S, the glass 10 first abuts against the sealing part 222, then squeezes and pushes the sealing part 222, causing it to enter the non-enclosed chamber and abut against and be fixed to the mounting part 221. Under the obstruction and further compression of the mounting part 221, the sealing part 222 deforms, ultimately tightly covering the glass 10, achieving both sealing and cushioning functions. Furthermore, after being pushed upwards by the glass 10, the sealing part 222 enters the side decorative strip 21, where it is protected from daily wind and sun erosion, significantly extending its service life.

[0074] Specifically, the top of the inner side plate 212 and the top of the outer side plate 211 are both connected to the connecting plate 213, and the inner side plate 212 and the outer side plate 211 are spaced apart. Thus, the inner side plate 212, the connecting plate 213, and the outer side plate 211 cooperate to form the mounting chamber 214. Furthermore, the mounting opening 215 is formed by the cooperation of the bottom of the inner side plate 212 and the bottom of the outer side plate 211.

[0075] Please see Figure 5 and Figure 6 For example, the bottom of the inner side panel 212 is provided with a bent portion 2121 that bends towards the outer side panel 211. The bent portion 2121 abuts against and limits the bottom surface of the mounting portion 221 in the vertical direction. The outer side panel 211 is provided with a first snap-fit ​​portion 2111, and the mounting portion 221 is provided with a second snap-fit ​​portion 2210. The first snap-fit ​​portion 2111 and the second snap-fit ​​portion 2210 engage with each other. In this way, the bent portion 2121 limits the mounting portion 221, preventing the mounting portion 221 from detaching downward from the side trim strip 21; and the first snap-fit ​​portion 2111 and the second snap-fit ​​portion 2210 engage with each other, so that the mounting portion 221 is snapped and fixed inside the side trim strip 21. Furthermore, both ends of the mounting portion 221 are limited in its width direction, so that it can be stably set on the side trim strip 21.

[0076] The bent part 2121 can also be understood as a hook, which hooks the mounting part 221 and plays a limiting role to prevent the mounting part 221 from falling off.

[0077] Specifically, the bent portion 2121 abuts against the connection position between the first end 2221 and the mounting portion 221.

[0078] To avoid the risk of fatigue cracking due to long-term repeated deformation, the connection between the sealing part 222 and the mounting part 221, that is, the connection between the first end 2221 and the mounting part 221, is specifically arranged adjacent to the bending part 2121. In this way, the connection between the sealing part 222 and the mounting part 221 is close to the bending part 2121, and the bending part 2121 can stably support the connection between the sealing part 222 and the mounting part 221.

[0079] Please see Figure 2 and Figure 3 Based on the aforementioned embodiment, the first end 2221 of the sealing portion 222 is provided as a curved portion, specifically, for example, L-shaped or C-shaped. An avoidance groove 2223 is provided on the inner side of the curved portion. The cross-sectional profile of the avoidance groove 2223 along its length direction is, for example, rectangular, V-shaped, or arc-shaped. The avoidance groove 2223 extends along the length direction of the sealing strip 22. The inner side of the curved portion refers to the side of the curved portion closer to the sealing portion 222. Thus, during the upward pressing of the sealing portion 222 by the glass 10, the avoidance groove 2223 is easily bent under stress, making the sealing portion 222 more prone to deformation, ensuring a smoother deformation process; moreover, it effectively solves the wrinkling problem during deformation, ensuring a smoother deformation process, and further ensuring that the connection between the sealing portion 222 and the mounting portion 221 avoids the active deformation area, thereby improving the durability and reliability of the sealing strip 22.

[0080] For example, the first snap-fit ​​portion 2111 includes a raised rib, and the second snap-fit ​​portion 2210 is correspondingly provided with a snap-fit ​​hole that engages with the raised rib, with the raised rib being snapped into the snap-fit ​​hole. Alternatively, the first snap-fit ​​portion 2111 is provided with a snap-fit ​​hole, and the second snap-fit ​​portion 2210 correspondingly includes a raised rib that engages with the snap-fit ​​hole, with the raised rib being snapped into the snap-fit ​​hole.

[0081] Due to the weight of the mounting part 221 and the elasticity released by the sealing part 222 after compression, the mounting part 221 may detach during vehicle operation or when the glass 10 is raised or lowered. Therefore, a support part 2112 is provided on the side of the outer panel 211 facing the inner panel 212, and the support part 2112 abuts against and limits the bottom surface of the mounting part 221 in the vertical direction. The support part 2112 includes, but is not limited to, protruding ribs, protrusions, or bosses provided on the side of the outer panel 211 facing the inner panel 212. The support part 2112 supports the mounting part 221, shares its weight, and allows the mounting part 221 to be stably engaged within the side trim strip 21.

[0082] Please see Figure 2 and Figure 3 For example, the second snap-fit ​​portion 2210 is provided as a snap-fit ​​hole, and the first snap-fit ​​portion 2111 is provided as a raised rib that snaps into the snap-fit ​​hole. The mounting portion 221 is provided with a first retaining head 2211 and a second retaining head 2212, which are spaced apart in the vertical direction and cooperate to form a snap-fit ​​hole. The first retaining head 2211 is closer to the sealing portion 222 than the second retaining head 2212, and the first retaining head 2211 abuts against the free end.

[0083] In order to cope with the changes in movement and pressure of the sealing part 222, the first clamping head 2211 was reinforced.

[0084] Please see Figure 5 For example, the maximum straight-line dimension of the first clamping head in the vertical direction is set as d, where 2.5mm ≤ d ≤ 4mm.

[0085] Specifically, d includes, but is not limited to, 2.5mm, 3mm, 3.5mm, 3.8mm, or 4mm. This allows the sealing portion 222 to receive more effective support and cushioning when lifted by the glass 10, thereby improving overall stability and reliability. Furthermore, when d is less than 2.5mm, the structural strength of the first retaining head 2211 will decrease, failing to provide effective support and cushioning, thus compromising overall stability and reliability. When d is greater than 4mm, the range of motion of the sealing portion 222 will be limited, the compression of the sealing portion 222 will be insufficient, and it will hinder the glass 10 from opening outwards.

[0086] For example, the first retaining head 2211 has a rounded corner 2213 on its side facing the free end. Optionally, the radius of the rounded corner 2213 is, for example, 2mm to 2.5mm. Specifically, the radius of the rounded corner 2213 is, for example, 2mm, 2.2mm, 2.4mm, or 2.5mm. In this way, the sealing part 222 can obtain more effective support and cushioning when it is lifted by the glass 10, thereby improving the overall stability and reliability.

[0087] Please see Figure 5 and Figure 6For example, the free end has a second flange 2225 bent in a direction away from the mounting portion 221. The second sealing structure 2226 is spaced apart from the second flange 2225 and surrounds it to form a retaining recess 2224. When the glass 10 is in the closed position, the second sealing structure 2226 seals against the glass 10. When the glass 10 is in the open position, the first flange 2113 extends into the retaining recess 2224 to engage the free end, fixing the free end and preventing it from falling off. This improves the installation stability of the sealing strip 22 and facilitates the opening and closing of the door. Furthermore, during the closing process of the glass 10, by pressing the sealing part 222 upward, the retaining recess 2224 can disengage from the retaining recess 2224 and move towards the mounting part 221. This facilitates the elastic deformation of the sealing part 222 and covers the top of the glass 10, thereby achieving better sealing performance and avoiding interference jamming failure. In addition, it can prevent the sealing part 222 from failing to return to its original state after the glass 10 is opened.

[0088] When the glass 10 is in the open state, the second flange 2225 and the first flange 2113 are engaged with each other, which can effectively prevent the sealing part 222 from detaching from the side decorative strip 21.

[0089] Optionally, when the sealing structure is in its naturally extended state, it is curved and protrudes in a direction away from the mounting portion 221. In this way, the sealing structure and the mounting portion 221 cooperate to form a non-closed chamber.

[0090] For example, the second flange 2225 has a third guide surface 22251 on the side opposite to the first flange 2113, and the mounting part 221 has a positioning recess 2214 that abuts against the free end. The third guide surface 22251 guides and engages with the inner wall of the positioning recess 2214. Thus, during the process of the glass 10 rising and pressing the sealing part 222, the second flange 2225 moves towards the positioning recess 2214. Due to the guiding engagement of the third guide surface 22251 with the inner wall of the positioning recess 2214, the free end can smoothly move into the positioning recess 2214, and the free end abuts and is positioned within the positioning recess 2214, improving stability and reliability. Conversely, when the glass 10 descends or the frameless door opens, due to the guiding engagement of the third guide surface 22251 with the inner wall of the positioning recess 2214, the sealing part 222 smoothly returns to its original shape under its own elastic force.

[0091] The third guide surface 22251 may be, but is not limited to, a flat or curved surface, as long as it can guide and cooperate with the inner wall of the positioning recess 2214.

[0092] For example, the mounting part 221 includes a main structure 2215. A first retaining head 2211 and a second retaining head 2212 are both disposed at one end of the main structure 2215. The first retaining head 2211 cooperates with the main structure 2215 to form a positioning recess 2214. The inner wall of the positioning recess 2214 smoothly transitions to the rounded corner 2213 of the first retaining head 2211. Thus, during the process of the glass 10 rising to compress the sealing part 222, after the third guide surface 22251 contacts the rounded corner 2213, it can smoothly continue to move into the positioning recess 2214. That is, it can prevent the second flange 2225 from interfering with and jamming the first retaining head 2211 during its movement towards the positioning recess 2214, thereby preventing the sealing part 222 from failing to return to its original state after the glass 10 is opened.

[0093] For example, the end face of the first flange 2113 is provided with a fourth guide surface 21131, and the side of the support arm 22261 facing the second flange 2225 is provided with a fifth guide surface 22263. When the sealing strip 22 switches between its natural state and its compressed state, the fourth guide surface 21131 and the fifth guide surface 22263 slide in engagement. Thus, during the process of the glass 10 rising to compress the sealing part 222, the sealing part 222 can move smoothly toward the mounting part 221 because the fourth guide surface 21131 and the fifth guide surface 22263 slide relative to each other.

[0094] Similarly, the fourth guide surface 21131 and the fifth guide surface 22263 are each independently adjusted and set according to actual needs, and are including but not limited to being flat or curved surfaces.

[0095] Please see Figure 2 , Figure 3 , Figure 5 and Figure 6In one specific embodiment, when the glass 10 is in the closed position, i.e., when the glass 10 is raised to the top, the sealing part 222 abuts against and is positioned with the mounting part 221. Specifically, the glass 10 presses against the sealing part 222 so that its free end enters the positioning recess 2214 and abuts against the positioning recess 2214. Furthermore, the end of the first flange 2113 abuts against the connection between the support arm 22261 and the abutting arm 22262. The connection between the support arm 22261 and the abutting arm 22262 is provided with a first guide surface 22264, which slides against the end face of the first flange 2113. The abutting arm 22262 abuts against the top end face 13 of the glass 10 to ensure a seal. For example, the top end face 13 of the glass 10 may be provided as an arc-shaped surface. Furthermore, the abutment arm 22262 has a second guide surface 22265 on the side opposite to the support arm 22261, and the second guide surface 22265 slides in engagement with the top end face 13 of the glass 10. Thus, during the opening of the glass 10, the top end face 13 of the glass 10 presses against the abutment arm 22262 and slides relative to the second guide surface 22265. When the abutment arm 22262 is pressed by the glass 10, the first guide surface 22264 slides relative to the end face of the first flange 2113, thereby enabling the frameless door to open and preventing jamming defects.

[0096] Therefore, the design of the first flange 2113 not only engages with the free end of the sealing part 222 when the glass 10 descends, but also holds the sealing part 222 in place when the glass 10 rises to the top, ensuring a tight seal between the sealing part 222 and the glass 10. Simultaneously, supported by the sealing part 222 and the first flange 2113, the glass 10 effectively suppresses shaking during vehicle operation, further reducing driving noise. This not only ensures the overall stability of the sealing strip 22 but also reduces its detachment rate during opening and closing, effectively preventing the sealing strip 22 from falling off during vehicle operation or when the glass 10 is raised or lowered. Furthermore, guided by the third guide surface 22251, the fourth guide surface 21131, and the fifth guide surface 22263, the sealing part 222 can move smoothly and be easily lifted upwards by the glass 10. Additionally, the coordinated action of the first guide surface 22264 and the second guide surface 22265 enables the frameless door to open and close smoothly.

[0097] The abutment arm 22262, support arm 22261, and sealing part 222 cooperate to form a "T" shape. Optionally, the included angle between the abutment arm 22262 and the support arm 22261 is, for example, an acute angle. Specifically, the included angle between the abutment arm 22262 and the support arm 22261 is α, where 40°≤α≤60°. This ensures smoother and more reliable guiding and sliding processes during the opening and closing of the frameless door.

[0098] In summary, the door sealing assembly and vehicle according to an embodiment of this application have at least the following advantages:

[0099] 1. Improved sealing and quietness: Relying on structural stability, reliability and dual sealing design, the overall sealing of the vehicle is greatly improved, and the quietness inside the vehicle is also enhanced.

[0100] 2. Seamless power outage escape: After eliminating the glass 10 short-fall system, the door can still be opened easily and smoothly to escape in the event of a power outage, without damaging any parts, ensuring safety in emergency situations;

[0101] 3. Lightweight vehicle design: By eliminating the glass 10 short-short-slit system, the vehicle's weight is effectively reduced, thereby improving the vehicle's energy efficiency;

[0102] 4. Reduced safety costs: The reduced vehicle weight lowers the performance requirements of components such as the braking system, thereby reducing related costs;

[0103] 5. Enhanced stability and reliability: The sealing strip 22 and glass 10 are more stable during driving and opening / closing, and are less likely to fall off, thus improving stability and reliability;

[0104] 6. Improved durability: The sealing strip 22 is better protected by the designer, and is protected from sun and rain erosion most of the time, significantly extending its service life.

[0105] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
