Description

Technical Field

[0001] The present application relates to the technical field of frameless vehicle doors, and in particular to a vehicle door sealing assembly and a vehicle. Background Art

[0002] Frameless door models in the related art generally feature an independent glass drop system (an independent opening and closing system or switch mechanism), specifically including a motor or linkage. When the door is opened, the glass drop system activates, quickly lowering the door glass by 5mm to 30mm, freeing it from the squeezed and accumulated sealing strips and ensuring uninterrupted door opening. When the door is closed, the door glass rises, squeezing the sealing strips, which wrap around the door glass and ensure a tight seal. Compared to models with framed doors, frameless doors have lower sealing performance. Summary of the Invention

DETAILED DESCRIPTION

[0034] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0035] See Figure 1 One embodiment of the present application provides a vehicle, comprising a vehicle body, frameless doors, and glass 10. The frameless doors are mounted on the vehicle body in an openable manner, and the specific opening method is, for example, to open by rotating or by sliding along the front-to-back direction of the vehicle body. The number of frameless doors includes, but is not limited to, one, two, three, four, or more. For example, there are four frameless doors, namely, 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 speaking, the sealing performance of frameless vehicle doors is lower than that of framed vehicle doors. To improve the sealing performance of frameless vehicle doors when closed, the vehicle, for example, also includes a door sealing assembly. The vehicle body includes a side panel 30, to which the door sealing assembly is fixedly mounted. The door sealing assembly specifically engages with the glass 10 in a sealing engagement. When the door is closed, it provides a good seal, providing sound insulation and waterproofing.

[0037] See also Figures 1 to 3 For example, the door sealing assembly includes a side panel trim strip 21 and a sealing strip 22. The side panel trim strip 21 is used to be installed on the side panel sheet metal 30. The sealing strip 22 is connected to the side panel trim strip 21.

[0038] See also Figure 2 and Figure 3 The sealing strip 22 includes a sealing portion 222 for sealingly engaging with the glass 10 and a first sealing structure 2228 connected to the sealing portion 222. The first sealing structure 2228 is configured to sealably engage with the inner side 12 of the glass 10 and is provided with at least two teeth 22281. Each tooth 22281 extends along the length of the sealing strip 22, with at least two teeth 22281 spaced apart in sequence along the direction in which the glass 10 is raised or lowered. When the glass 10 is in the closed position, the at least two teeth 22281 are in sealing engagement with the inner side 12 of the glass 10.

[0039] The above-mentioned 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 squeezes the sealing portion 222, causing the sealing portion 222 to deform to form a press-fit seal on the top end face 13 of the glass 10, and the first sealing structure 2228 is sealed against the inner side surface 12 of the glass 10 through at least two teeth 22281, forming at least two seals, thereby ensuring better sealing after the glass 10 is closed; on the other hand, the first sealing structure 2228 that plays a sealing role is interconnected with the sealing portion 222, which is convenient for disassembly and assembly.

[0040] See also 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 is in sealing contact with the inner side surface 12 of the glass 10. At least two teeth 22281 are specifically provided at the bottom of the sealing plate. The sealing skirt extends along the length direction 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 include but are not limited to being integrally formed by, for example, 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 portion 222 and is spaced apart from the first sealing structure 2228. The second sealing structure 2226 is configured 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 portion 222, and the second sealing structure 2226 support the glass 10, effectively suppressing the shaking caused by the vehicle during driving and further reducing driving noise.

[0043] The sealing strip 22 has a natural state and a compressed state and can be switched between the natural state and the compressed state.

[0044] Specifically, when the glass 10 rises and squeezes the sealing portion 222, that is, when the sealing strip 22 is in a compressed state, the sealing portion 222 tightly contacts the top end surface 13 of the glass 10 to cover the top end surface 13 of the glass 10. The first sealing structure 2228 contacts and positions the inner side surface 12 of the glass 10, and the second sealing structure 2226 bends toward the glass 10 and seals and contacts the glass 10, thereby improving the sealing performance and achieving good sound insulation, dustproofing, and waterproofing effects. Furthermore, when the first sealing structure 2228 contacts and positions the inner side surface 12 of the glass 10, due to the lever effect, while the sealing portion 222 is squeezed and deformed, the free end of the first sealing structure 2228 moves toward the inner side surface of the supporting glass 10 and contacts the inner side surface of the supporting glass 10, thereby stably supporting the inner side surface 12 of the glass 10 and ensuring good sealing performance.

[0045] Specifically, the second sealing structure 2226 can abut against either the top end surface 13 of the glass 10 or the outer side surface 11 of the glass 10. In this embodiment, the second sealing structure 2226 preferably abuts against the top end surface 13 of the glass 10. This allows the glass 10 to open smoothly and close smoothly when opened outward, thus avoiding interference and jamming during the door opening and closing process.

[0046] Among them, the outer side surface 11 of the glass 10 refers to the side of the glass 10 facing the external environment of the vehicle; the inner side surface 12 of the glass 10 refers to the side of the glass 10 facing away from the external environment of the vehicle; the top end surface 13 of the glass 10 refers to the part of the glass 10 connected to the outer side surface 11 of the glass 10 and the inner side surface 12 of the glass 10.

[0047] See also Figure 2 、 Figure 3 、 Figure 5 and Figure 6 For example, the second sealing structure 2226 includes a support arm 22261 and an abutting arm 22262. The top of the support arm 22261 is connected to the sealing portion 222, and the abutting arm 22262 is connected to the bottom of the support arm 22261. The abutting arm 22262 is arranged at an angle to the support arm 22261, and the abutting arm 22262 is used to abut against the glass 10. In this way, when the glass 10 squeezes the sealing portion 222, the sealing portion 222 deforms and abuts tightly against the top end face 13 of the glass 10. At the same time, the abutting arm 22262 moves toward the glass 10 and abuts tightly against the glass 10. Since the abutting arm 22262 is arranged at an angle to the support arm 22261, it can play a buffering role, thereby ensuring sealing.

[0048] For example, the side trim strip 21 includes an outer panel 211. The bottom of the outer panel 211 is provided with a first flange 2113 that bends toward the second sealing structure 2226. When the glass 10 is in the closed position, that is, when the sealing strip 22 is compressed, the end of the first flange 2113 abuts the second sealing structure 2226. This supports the second sealing structure 2226, not only improving the seal line but also effectively suppressing vehicle vibration during driving, further reducing driving noise.

[0049] See also Figures 1 to 3 For example, when the sealing strip 22 is in a natural state, that is, when the glass 10 is in a closed position, a clearance gap is provided between the bottom of the outer panel 211 and the top of the glass 10 in the vertical direction. Figure 1 The spacing D in the position is shown.

[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 that the frameless door can be opened smoothly, the calculation of the gap between the glass 10 and the side trim 21 needs to take into account the deviation between the actual and theoretical values. Figure 1, the vertical distance between the bottom of the outer panel 211 and the glass 10 raised to the top is set to D, the vertical deviation value of the glass 10 when it is raised to the top is set to A, and the deviation value of the glass 10 along the lifting trajectory when it is raised to the top is set to B. The deviation value of the glass 10 along the lifting trajectory when it 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 to β, and the safety margin is set to C. The safety margin C can be flexibly adjusted and set according to factors including but not limited to assembly deviation and the surface tolerance of the side panel decorative 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 meeting this condition, it can be ensured that there is no interference between the glass 10 and the side panel decorative strip 21, thereby ensuring the smooth opening of the car door.

[0052] For example, the sealing strip 22 further includes a mounting portion 221 , which is mounted in the side panel trim strip 21 . The mounting portion 221 is connected to a sealing portion 222 , and the mounting portion 221 and the sealing portion 222 enclose a non-enclosed chamber 223 . An opening 224 of the non-enclosed chamber 223 is close to the outer panel 211 .

[0053] See also 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 portion 222, the sealing portion 222 is engaged with the bottom of the outer panel 211, and an unsealed chamber 223 is formed between the sealing portion 222 and the mounting portion 221. The unsealed chamber 223 provides a deformation space, allowing the sealing strip 22 to easily deform elastically when subjected to the squeezing force of the glass 10.

[0054] See also Figures 1 to 3 When the sealing strip 22 is in a compressed state and the glass 10 is correspondingly in a closed position, the non-enclosed chamber 223 is used to accommodate the deformation of the sealing portion 222 to form a press-fit seal on the glass 10, and an avoidance gap is provided between the bottom of the outer plate 211 and the top of the glass 10 in the vertical direction.

[0055] In summary, on the one hand, when the sealing strip 22 is in a natural state, that is, the glass 10 is in the closed position, since there is an avoidance gap in the vertical direction between the bottom of the outer panel 211 and the top of the glass 10, during the door opening and closing process, the top of the glass 10 will not be interfered with by the outer panel 211 without lowering the height to adjust the height, thereby avoiding rigid obstruction. When the car door is powered off, it can be opened normally under the action of external force, which improves safety. Compared with the violent door opening method, it can greatly reduce the damage to the sealing strip 22, thereby facilitating long-term normal use. On the other hand, the non-enclosed chamber is used to accommodate the deformation of the sealing portion 222 to form a press-fit seal on the glass 10, thereby ensuring the sealing and reliability of the glass 10 after closing. In addition, when the glass 10 is in the open position, the sealing portion 222 and the bottom of the outer panel 211 are clamped with each other, and the outer panel 211 supports the sealing portion 222 to prevent the sealing portion 222 from falling downward and causing the door to be unable to be opened and closed normally.

[0056] Since the sealing portion 222 is engaged with the bottom of the outer panel 211 , it not only ensures the overall stability of the sealing strip 22 , but also reduces its falling rate during the opening and closing process, thereby effectively preventing the sealing strip 22 from falling off during vehicle driving or the lifting of the glass 10 .

[0057] In addition, since the mounting portion 221 and the sealing portion 222 enclose a non-enclosed chamber 223, the opening portion 224 of the non-enclosed chamber 223 is located on the outside of the sealing strip 22, that is, the sealing strip 22 adopts a semi-open structure. Compared with a closed structure, when the glass 10 is switched to the open position, the sealing portion 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] See also Figures 1 to 3 When the sealing strip is in a compressed state, that is, the frameless door is in a closed position, during the process of the glass 10 rising to the top, the lifting direction of the glass 10 is, for example, Figure 1 As shown by the double arrow S in the figure, the glass 10 first abuts the sealing portion 222, then squeezes and lifts the sealing portion 222, allowing the sealing portion 222 to enter the non-enclosed cavity and abut against the mounting portion 221. The sealing portion 222 deforms under the obstruction and further squeezing of the mounting portion 221, and finally tightly covers the glass 10, achieving both sealing and cushioning functions.

[0059] When the glass 10 is at the top, the frameless door is switched from open to closed, that is, the frameless door is switched from open to closed. Figure 4 Switch the position shown to Figure 1 The direction of movement of the frameless door is as follows: Figure 1As shown by the double arrow K in the figure, the glass 10 contacts the sealing portion 222, squeezing and lifting the sealing portion 222, causing the sealing portion 222 to enter the non-enclosed chamber 223 and abut against the mounting portion 221. The sealing portion 222 deforms under the obstruction and further squeezing of the mounting portion 221, ultimately tightly enveloping the glass 10, achieving both sealing and cushioning functions.

[0060] On the contrary, when the frameless door is in the closed position and the glass 10 is at the top, in the process of switching the frameless door from closed to open, that is, the frameless door is switched from closed to open, for example, Figure 1 Switch the position shown to Figure 4 In the position shown, the sealing portion 222 returns to its original shape under the action of its own elastic force and is engaged with the bottom of the outer plate 211. The outer plate 211 supports the sealing portion 222 to prevent the sealing portion 222 from falling downward and causing the door to be unable to be opened and closed normally.

[0061] As can be seen, the difference between the frameless doors of the present application and those of related art is that the frameless doors of this application do not require the glass 10 to be lowered 5mm to 30mm when opening and closing the door. Because the bottom of the outer panel 211 of the side trim 21 is higher than the top of the raised glass 10 and a clearance exists between the outer panel 211 and the top of the glass 10, the door opening and closing process is not interfered with by the side trim 21, thus avoiding rigid obstruction. Even if the glass 10 is not lowered during the opening process of the frameless door, the door can still be opened smoothly without damaging any vehicle components. Furthermore, the sealing strip 22 does not fall off during the door 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 erosion caused by daily wind, sun and rain, thereby ensuring the stability of the sealing performance, but also assist in guiding the deformation of the sealing strip 22.

[0063] Building on the previous embodiment, the frameless door in this embodiment eliminates the glass 10 short-drop 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 improving vehicle safety, but also effectively reduces vehicle manufacturing costs. Furthermore, the door's sealing and sound insulation are significantly improved, achieving dual optimization of lightweight and sealing performance, further enhancing the driving experience.

[0064] For example, the opening 224 is extended along the length direction of the sealing strip 22 , extending 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.

[0065] For example, a first end 2221 of the sealing portion 222 along its width direction is connected to the mounting portion 221 , and a second end 2222 of the sealing portion 222 along its width direction is a free end that is snap-fitted with the bottom of the outer plate 211 .

[0066] The width direction of the sealing portion 222 is as follows: Figure 1 The direction is shown by the double arrow W.

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

[0068] The free end is not directly connected to the mounting portion 221 , so that it can move toward the mounting portion 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 molding process of the side trim strip 21 is mainly extrusion, bending and milling, and the material used is, for example, mainstream 6 series aluminum alloy. In this way, it has 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 mounting portion 221, being more rigid, can be stably mounted within the side trim strip 21; while the sealing portion 222, being less rigid, is more susceptible to deformation under stress, thereby ensuring sealing and allowing for easy restoration to its original shape.

[0071] To ensure the processing quality and efficiency of the sealing strip 22, the mounting portion 221 and the sealing portion 222 are integrally formed, for example, using a two-material co-extrusion process. Optionally, the sealing strip 22 is co-extruded using EPDM or another elastic material. The mounting portion 221 is made of EPDM solid rubber, a non-foamed material, which provides greater hardness and enhances installation stability within the side trim strip 21. The sealing portion 222 is made of EPDM sponge rubber, a foamed material, which provides a lower hardness, allowing for elastic deformation under external forces and facilitating return to its original shape when the glass 10 is switched to the open position.

[0072] For example, the mounting portion 221 may be mounted in the side panel trim 21 by snap-fitting, bonding, welding, or other means. It may also be fixed to the side panel trim 21 using fasteners such as pins, screws, or rivets. In this embodiment, to improve assembly and disassembly efficiency of the mounting portion 221, the mounting portion 221 is mounted in the side panel trim 21 by snap-fitting, for example.

[0073] See also Figure 2 and Figure 3 For example, the side trim strip 21 also includes an inner panel 212 and a connecting panel 213. The inner panel 212 is connected to the outer panel 211 through the connecting panel 213. The inner panel 212, the connecting panel 213 and the outer panel 211 enclose a mounting chamber 214. The bottom of the inner panel 212 and the bottom of the outer panel 211 are spaced apart to form a mounting opening 215. The mounting opening 215 is connected to the mounting chamber 214. The mounting portion 221 is snap-fitted into the mounting chamber 214, and the sealing portion 222 is provided at the mounting opening 215. The sealing portion 222 is located below the mounting portion 221 and is exposed through the mounting opening 215. When the frameless door is in the closed position, in the process of the glass 10 rising to the top, the lifting direction of the glass 10, for example Figure 1 As shown by the double arrow S in the image, the glass 10 first abuts the sealing portion 222, which is then squeezed and lifted, forcing the sealing portion 222 into the non-enclosed chamber and into abutment with the mounting portion 221. The sealing portion 222 deforms under the resistance and further compression of the mounting portion 221, ultimately tightly enveloping the glass 10 and achieving both sealing and cushioning functions. Furthermore, after being lifted upward by the glass 10, the sealing portion 222 enters the side panel molding 21, where it is protected from everyday weather and sun, significantly extending its service life.

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

[0075] See also Figure 5 and Figure 6 For example, the bottom of the inner panel 212 is provided with a bent portion 2121 that bends toward one side of the outer panel 211. The bent portion 2121 abuts against the bottom surface of the mounting portion 221 in the vertical direction to limit position. The outer panel 211 is provided with a first clamping portion 2111, and the mounting portion 221 is provided with a second clamping portion 2210. The first clamping portion 2111 and the second clamping portion 2210 engage with each other. In this way, the bent portion 2121 limits the mounting portion 221, preventing the mounting portion 221 from disengaging downward from the side panel trim 21. Furthermore, the first clamping portion 2111 and the second clamping portion 2210 engage with each other, so that the mounting portion 221 is clamped and fixed within the side panel trim 21. Furthermore, the mounting portion 221 is limited at both opposite ends along its width direction, allowing it to be stably mounted on the side panel trim 21.

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

[0077] Specifically, the bending portion 2121 abuts against a 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 portion 222 and the mounting portion 221, that is, the connection between the first end 2221 and the mounting portion 221, is specifically disposed adjacent to the bent portion 2121. In this way, the connection between the sealing portion 222 and the mounting portion 221 is close to the bent portion 2121, and the bent portion 2121 can stably support the connection between the sealing portion 222 and the mounting portion 221.

[0079] See also Figure 2 and Figure 3 On the basis of the above-mentioned embodiment, the first end 2221 of the sealing portion 222 is provided with a curved portion, specifically, for example, an L-shape or a C-shape. An avoidance groove 2223 is provided on the inner side of the curved portion. The cross-sectional profile of the avoidance groove 2223 along the length direction is, for example, rectangular, V-shaped or arc-shaped. The avoidance groove 2223 is extended along the length direction of the sealing strip 22. Among them, the inner side of the curved portion refers to the side of the curved portion close to the sealing portion 222. In this way, when the sealing portion 222 is squeezed upward by the glass 10, the avoidance groove 2223 is easily bent by the force, and then the sealing portion 222 is easily deformed, ensuring that the deformation process is smoother; moreover, it can effectively solve the wrinkle problem during deformation, ensuring that the deformation process is smoother, and further ensure 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 engaging portion 2111 includes a raised rib, and the second engaging portion 2210 is correspondingly provided with a engaging hole that engages with the raised rib, and the raised rib is engaged in the engaging hole. Alternatively, the first engaging portion 2111 is provided with a engaging hole, and the second engaging portion 2210 includes a raised rib that engages with the engaging hole, and the raised rib is engaged in the engaging hole.

[0081] Due to the self-weight characteristics of the mounting portion 221 and the elastic force released by the sealing portion 222 after being squeezed, the mounting portion 221 may fall off during the driving of the vehicle or during the lifting and lowering of the glass 10. Based on this, a supporting portion 2112 is provided on the side of the outer panel 211 facing the inner panel 212. The supporting portion 2112 is abutted against the bottom surface of the mounting portion 221 in the vertical direction for limiting position. The supporting portion 2112 includes but is not limited to raised ribs, bumps or bosses provided on the side of the outer panel 211 facing the inner panel 212. The supporting portion 2112 can support the mounting portion 221, share the weight of the mounting portion 221, and enable the mounting portion 221 to be stably clamped and provided in the side trim strip 21.

[0082] See also Figure 2 and Figure 3 For example, the second engaging portion 2210 is configured as a engaging hole, and the first engaging portion 2111 is configured as a raised rib that engages with the engaging hole. The mounting portion 221 is provided with a first engaging head 2211 and a second engaging head 2212. The first engaging head 2211 and the second engaging head 2212 are spaced apart vertically and cooperate to form the engaging hole. The first engaging head 2211 is closer to the sealing portion 222 than the second engaging head 2212, and the first engaging head 2211 abuts against the free end.

[0083] In order to cope with the movement and pressure of the sealing portion 222, the first holding head 2211 is reinforced.

[0084] See also Figure 5 For example, the maximum linear dimension of the vertical profile of the first holding head is set to d, 2.5 mm ≤ d ≤ 4 mm.

[0085] Specifically, d includes, but is not limited to, 2.5 mm, 3 mm, 3.5 mm, 3.8 mm, or 4 mm. 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 2.5 mm, the structural strength of the first retaining head 2211 is reduced, rendering it ineffective in providing support and cushioning, and thus failing to ensure overall stability and reliability. When d is greater than 4 mm, the range of motion of the sealing portion 222 is limited, resulting in insufficient compression of the sealing portion 222 and hindering the outward opening of the glass 10.

[0086] For example, the side of the first retaining head 2211 facing the free end is provided with a rounded corner 2213. Optionally, the radius of the rounded corner 2213 is, for example, 2 mm to 2.5 mm. Specifically, the radius of the rounded corner 2213 is, for example, 2 mm, 2.2 mm, 2.4 mm, or 2.5 mm. This allows the sealing portion 222 to obtain more effective support and cushioning when being lifted by the glass 10, thereby improving overall stability and reliability.

[0087] See also Figure 5 and Figure 6For example, the free end is provided with a second flange 2225 that bends away from the mounting portion 221. A second sealing structure 2226 is spaced apart from the second flange 2225 and encloses 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 and retains the free end, preventing it from falling off. This improves the installation stability of the sealing strip 22 and facilitates door opening and closing. In addition, during the closing process of the glass 10, by squeezing the sealing portion 222 upward, the retaining recess 2224 can be disengaged from the retaining recess 2224 and move toward the mounting portion 221. This is conducive to the elastic deformation of the sealing portion 222 and covering the top of the glass 10, thereby having better sealing performance and avoiding interference jamming failures, thereby preventing the sealing portion 222 from being unable 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 portion 222 from being separated from the side decorative strip 21 .

[0089] Optionally, when the sealing structure is in a naturally extended state, the sealing structure 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 with each other to form a non-enclosed chamber.

[0090] For example, a third guide surface 22251 is provided on the side of the second flange 2225 facing away from the first flange 2113. The mounting portion 221 is provided with a positioning recess 2214 that abuts the free end. The third guide surface 22251 guides and engages with the inner wall of the positioning recess 2214. As the glass 10 rises and presses against the sealing portion 222, the second flange 2225 moves toward the positioning recess 2214. The third guide surface 22251 guides and engages with the inner wall of the positioning recess 2214, allowing the free end to smoothly enter the positioning recess 2214 and abut against the positioning recess 2214, thereby enhancing stability and reliability. Conversely, when the glass 10 is lowered or the frameless door is opened, the sealing portion 222 smoothly returns to its original shape under its own elastic force, due to the third guide surface 22251 guiding and engaging with the inner wall of the positioning recess 2214.

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

[0092] For example, the mounting portion 221 includes a main structure 2215. The first holding head 2211 and the second holding head 2212 are both disposed at one end of the main structure 2215. The first holding 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 arc corner 2213 of the first holding head 2211. In this way, during the process of the glass 10 rising and squeezing the sealing portion 222, after the third guide surface 22251 contacts the arc corner 2213, it can smoothly continue to move into the positioning recess 2214. In other words, the second flange 2225 can be prevented from interfering with the first holding head 2211 during its movement toward the positioning recess 2214, thereby preventing the sealing portion 222 from being unable to return to its original state after the glass 10 is opened.

[0093] For example, a fourth guide surface 21131 is provided on the end surface of the first flange 2113, and a fifth guide surface 22263 is provided on the side of the support arm 22261 facing the second flange 2225. When the sealing strip 22 switches between the natural and compressed states, the fourth guide surface 21131 and the fifth guide surface 22263 slide together. As the glass 10 rises and presses against the sealing portion 222, the sliding movement between the fourth guide surface 21131 and the fifth guide surface 22263 allows the sealing portion 222 to smoothly move closer to the mounting portion 221.

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

[0095] See also Figure 2 、 Figure 3 、 Figure 5 and Figure 6In a specific embodiment, when the glass 10 is in the closed position, that is, when the glass 10 is raised to the top, the sealing portion 222 is abutted and positioned against the mounting portion 221. Specifically, the glass 10 presses the sealing portion 222 so that the free end enters the positioning recess 2214 and abuts and cooperates with the positioning recess 2214. In addition, 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, and the first guide surface 22264 slides with the end surface of the first flange 2113. The abutting arm 22262 abuts against the top end surface 13 of the glass 10 to ensure sealing. For example, the top end surface 13 of the glass 10 is configured as an arc-shaped surface. In addition, a second guide surface 22265 is provided on the side of the abutting arm 22262 facing away from the supporting arm 22261. The second guide surface 22265 slidably engages with the top end surface 13 of the glass 10. Thus, when the glass 10 is opened, the top end surface 13 of the glass 10 presses the abutting arm 22262 and slides relative to the second guide surface 22265. When the abutting arm 22262 is pressed by the glass 10, the first guide surface 22264 slides relative to the end surface of the first flange 2113, thereby enabling the frameless door to open and preventing the possibility of a jamming defect.

[0096] As can be seen, the design of the first flange 2113 not only engages the free end of the sealing portion 222 when the glass 10 descends, but also supports the sealing portion 222 when the glass 10 reaches the top, ensuring that the sealing portion 222 and the glass 10 are tightly wrapped and sealed. Furthermore, supported by the sealing portion 222 and the first flange 2113, the glass 10 can effectively suppress shaking during vehicle operation, further reducing driving noise. This not only ensures the overall stability of the sealing strip 22 but also reduces its chance of falling off 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 portion 222 can move smoothly and be smoothly lifted upward by the glass 10. Furthermore, the coordinated action of the first guide surface 22264 and the second guide surface 22265 ensures smooth opening and closing of the frameless door.

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

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

[0099] 1. Improved sealing and quietness: Thanks to structural stability, reliability, and a double-sealing design, the vehicle's overall sealing is significantly improved, and the quietness of the interior is also enhanced;

[0100] 2. Non-destructive power-off escape: After the glass 10-minute short-drop system is eliminated, you can still easily and smoothly open the door to escape in the event of a power outage without destroying any parts, ensuring safety in emergency situations;

[0101] 3. Vehicle lightweighting: By eliminating the glass 10 short drop system, the vehicle body weight is effectively reduced, thereby improving the vehicle's energy efficiency;

[0102] 4. Reduce safety costs: The reduction in vehicle weight reduces the performance requirements for components such as the brake system, thereby reducing related costs;

[0103] 5. Enhanced stability and reliability: The sealing strip 22 and the glass 10 are more stable during driving and opening and closing, and are not easy to fall off, thereby improving stability and reliability;

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