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 for frameless doors), 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, and the sealing strips wrap around the door glass, ensuring a tight seal.

[0003] However, the door's opening is limited by the glass drop system. If the vehicle loses power, the door glass cannot descend smoothly and escape from the compressed and accumulated sealing strips, preventing the door from opening smoothly. This poses a significant safety hazard in emergency escape scenarios. Furthermore, the glass drop system is heavy, adding approximately 2.3kg to each door and 9.2kg to the overall weight of a four-door vehicle, increasing manufacturing costs.

[0004] Based on this, a proposal has been made to configure the sealing strip as a combination of a rigid portion and a soft lip. The rigid portion is fixed to the side trim strip, while the soft lip abuts against the door glass to ensure a tight seal. The soft lip allows for relatively easy compression and deformation. Even if the glass drop system loses power, the door glass and sealing strip can be squeezed together and eventually separated during the forced opening of the door. This prevents the frameless door from being unable to open after the glass drop system loses power. However, after a period of use, the sealing strip can affect the closed state of the door, thereby affecting driving safety and limiting its use cases. Summary of the Invention

[0005] Based on this, it is necessary to overcome the defects of the existing technology and provide a door sealing assembly and a vehicle, which can enable the door to open normally when the power is off, and can be used for a long time with improved safety.

DETAILED DESCRIPTION

[0040] 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.

[0041] After a period of use, the sealing strips in the related technology will affect the state of closing the car door, thereby affecting driving safety and leading to the problem of limited usage scenarios. The reason for this problem is that although the soft lip design allows the glass to be squeezed and detached, it has poor recovery properties, and it is difficult for the sealing strip to recover from the detached state to the original installation state, which affects the state of closing the car door, thereby affecting driving safety and limiting the usage scenarios.

[0042] Based on the above reasons, the present application provides a vehicle door sealing assembly and a vehicle, which can enable the vehicle door to open normally when the power is off and can be used for a long time, thereby improving safety.

[0043] See Figure 1The vehicle includes a vehicle body, frameless doors, and glass 10. The frameless doors are mounted on the vehicle body so as to be openable, for example, by rotating. 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.

[0044] To enhance the sealing performance of the frameless door after closing, the vehicle also includes a door seal assembly 20. The vehicle body includes a side panel 30, to which the door seal assembly 20 is fixedly mounted. The door seal assembly 20 seals against the glass 10, providing a good seal when the door is closed, providing sound insulation and waterproofing.

[0045] See also Figures 1 to 3 For example, the door sealing assembly 20 includes a side panel trim strip 21 and a sealing strip 22. The side panel trim strip 21 is mounted on the side panel sheet metal 30, and can be fixed to the side panel sheet metal 30 by fasteners such as screws, pins, rivets, or clips. Alternatively, the side panel trim strip 21 can be fixed to the side panel sheet metal 30 by bonding or welding. The specific installation method can be flexibly adjusted and configured according to actual needs and is not limited here.

[0046] The side trim strip 21 includes an outer panel 211. A sealing strip 22 is connected to the side trim strip 21 and includes a mounting portion 221 and a sealing portion 222. The mounting portion 221 is mounted within the side trim strip 21 and connected to the sealing portion 222. The sealing portion 222 is configured to abut against the glass 10.

[0047] The sealing strip 22 has a natural state and a compressed state and can be switched between the natural state and the compressed state.

[0048] See also Figures 4 to 6 Specifically, when the sealing strip 22 is in a natural state, that is, when the glass 10 is in an open position, the top of the glass 10 is separated from the sealing portion 222, the sealing portion 222 and the bottom of the outer panel 211 are engaged with each other, and a non-enclosed chamber 223 is formed between the sealing portion 222 and the mounting portion 221. The non-enclosed chamber 223 provides a deformation space, and the sealing strip 22 is prone to elastic deformation when subjected to the squeezing force of the glass 10. The opening 224 of the non-enclosed chamber 223 is located on the outside of the sealing strip 22. The outside of the sealing strip 22 refers to the side of the sealing strip 22 facing the external environment of the vehicle body, and the inside of the sealing strip 22 refers to the side of the sealing strip 22 facing away from the external environment of the vehicle body.

[0049] See also Figures 1 to 3When the sealing strip 22 is in a compressed state and the glass 10 is 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 escape gap is provided between the bottom of the outer plate 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] The above-mentioned vehicle door sealing assembly 20 and vehicle, on the one hand, when the sealing strip 22 is in a compressed state, 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 process of opening and closing the door, the top of the glass 10 will not be interfered by the outer panel 211 without lowering the height to adjust the door height, thereby avoiding rigid obstruction. When the door is powered off, it can be opened normally under the action of external force, thereby improving safety. In addition, 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 223 is used to accommodate the deformation of the sealing portion 222 to form a press-fit seal on the glass 10, thereby ensuring that the glass The sealing and reliability of the glass 10 after closing are improved; in addition, when the sealing strip 22 is in the natural state, the sealing portion 222 and the bottom of the outer plate 211 are engaged with each other, and 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; in addition, since the mounting portion 221 and the sealing portion 222 are enclosed to form 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 the closed structure, when the sealing strip 22 switches to the natural state, 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.

[0052] See also Figures 1 to 3 When the frameless door is in the 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 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, and finally tightly wraps the glass 10, achieving both sealing and cushioning functions.

[0053] 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 1The direction of movement of the frameless door is as follows: Figure 1 As 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] Building on the previous embodiment, the frameless door in this embodiment eliminates the glass 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 performance are significantly improved, achieving dual optimization of lightweight and sealing performance, further enhancing the driving experience.

[0058] 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 1When the sealing strip 22 is in a compressed state, the vertical distance between the bottom of the outer plate 211 and the top of the glass 10 is set to D, the vertical deviation value when the glass 10 is raised to the top is set to A, and the deviation value along the lifting track when the glass 10 is raised to the top is set to B. The deviation value along the lifting track when the glass 10 is raised to the top refers to the difference between the actual value and the target value along the lifting track when the glass 10 is raised to the top.

[0059] The angle between the glass 10's lifting trajectory 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 based on factors including, but not limited to, assembly deviations and the surface tolerances of the side trim 21. The specific value is not specified here. According to the trigonometric relationship, A = B * Sin β. Therefore, D > B * Sin β + C. By meeting this condition, there is no interference between the glass 10 and the side trim 21, ensuring smooth door opening.

[0060] 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.

[0061] 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 set as a free end; the free end is snap-fitted with the bottom of the outer plate 211 .

[0062] The width direction of the sealing portion 222 is as follows: Figure 1 The direction is shown by the double arrow W.

[0063] Specifically, when the sealing strip 22 is in a natural state, that is, when the glass 10 is in an open position, the free end is engaged with the bottom of the outer panel 211; when the sealing strip 22 is in a compressed state, that is, when the glass 10 is in a closed position, the free end moves toward the mounting portion 221 and abuts against the mounting portion 221.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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 1As 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.

[0070] 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.

[0071] See also Figure 5 and Figure 6 For example, the bottom of the inner panel 212 is provided with a first flange 2121 that is bent toward one side of the outer panel 211. The first flange 2121 abuts against the bottom surface of the mounting portion 221 in the vertical direction to limit its 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 are engaged with each other. In this way, the first flange 2121 limits the mounting portion 221, preventing it from disengaging from the side panel trim 21. Furthermore, the first clamping portion 2111 and the second clamping portion 2210 are engaged with each other, so that the mounting portion 221 is fixed in place 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.

[0072] The first flange 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.

[0073] Specifically, the first flange 2121 abuts against the connection position between the first end 2221 and the mounting portion 221 .

[0074] 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 first flange 2121. In this way, the connection between the sealing portion 222 and the mounting portion 221 is close to the first flange 2121, and the first flange 2121 can stably support the connection between the sealing portion 222 and the mounting portion 221.

[0075] See also Figure 2and 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] In order to cope with the movement and pressure of the sealing portion 222, the first holding head 2211 is reinforced.

[0080] See also Figure 5 For example, the maximum linear dimension of the profile of the first holding head in the vertical direction is set to d, 2.5mm≤d≤4mm.

[0081] 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.

[0082] 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.

[0083] See also Figure 5 and Figure 6 For example, the bottom of the outer panel 211 is provided with a second flange 2113 that bends toward one side of the inner panel 212. A retaining recess 2224 is provided at the free end. When the sealing strip 22 is in its natural state, the retaining recess 2224 engages with the second flange 2113. Thus, when the glass 10 is in the open position, the second flange 2113 extends into the retaining recess 2224 and retains the free end, securing it and preventing it from falling off. This improves the installation stability of the sealing strip 22 and facilitates door opening and closing. Furthermore, when the glass 10 is closed, by squeezing the sealing portion 222 upward, the retaining recess 2224 can disengage from the retaining recess 2224 and move toward the mounting portion 221. This facilitates elastic deformation of the sealing portion 222, allowing it to cover the top of the glass 10, thereby ensuring a better seal and preventing interference jamming. This prevents the sealing portion 222 from being unable to return to its original shape after the glass 10 is opened.

[0084] For example, the free end is provided with a bent portion 2225 that bends away from the mounting portion 221. The free end is also provided with a first sealing structure 2226. The first sealing structure 2226 is spaced apart from the bent portion 2225 and cooperates to form a retaining recess 2224. When the sealing strip 22 is compressed and the glass 10 is in the closed position, the first sealing structure 2226 seals against the glass 10. As a result, when the glass 10 rises and presses against the sealing portion 222, not only does the sealing portion 222 tightly abut against the top end face 13 of the glass 10, enveloping it, but the first sealing structure 2226 also bends toward the glass 10 and seals against it, thereby improving sealing performance and providing excellent sound insulation, dustproofing, and waterproofing.

[0085] Specifically, the first sealing structure 2226 can abut against the top end surface 13 of the glass 10 or against the side surface of the glass 10. In this embodiment, the first 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 it is opened outward, thus avoiding interference and jamming during the door opening and closing process.

[0086] 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.

[0087] For example, the sealing portion 222 includes a first main structure 2227. A first sealing structure 2226 is connected to the first main structure 2227. The first sealing structure 2226 includes a support arm 22261 and an abutting arm 22262. The top of the support arm 22261 is connected to the first main structure 2227, and the bent portion 2225 is connected to the first main structure 2227. The support arm 22261 and the bent portion 2225 are spaced apart and enclose a retaining recess 2224. The abutting arm 22262 is connected to the bottom of the support arm 22261, and the abutting arm 22262 is arranged at an angle to the support arm 22261, and the abutting arm 22262 abuts against the glass 10.

[0088] The bent portion 2225 is disposed on the side of the first main structure 2227 facing away from the mounting portion 221, that is, it is bent toward the side of the first main structure 2227 facing away from the mounting portion 221. When the glass 10 is in the open state, the bent portion 2225 and the second flange 2113 engage with each other, effectively preventing the sealing portion 222 from separating from the side panel trim 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 223.

[0090] For example, a first guide surface 22251 is provided on the side of the bent portion 2225 facing away from the second flange 2113, and the mounting portion 221 is provided with a positioning recess 2214 that abuts against the free end. When the sealing strip 22 switches between its natural and compressed states, the first 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 bent portion 2225 moves toward the positioning recess 2214. The first 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 descends or when the frameless door is opened, the first guide surface 22251 guides and engages with the inner wall of the positioning recess 2214, allowing the sealing portion 222 to smoothly return to its original state under its own elastic force.

[0091] The first 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 second main body structure 2215. The first holding head 2211 and the second holding head 2212 are both disposed at one end of the second main body structure 2215. The first holding head 2211 and the second main body structure 2215 cooperate 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 first guide surface 22251 contacts the arc corner 2213, it can smoothly continue to move into the positioning recess 2214. In other words, the bending portion 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 second guide surface 21131 is provided on the end surface of the second flange 2113, and a third guide surface 22263 is provided on the side of the support arm 22261 facing the bent portion 2225. When the sealing strip 22 switches between the natural and compressed states, the second guide surface 21131 and the third guide surface 22263 slide together. As the glass 10 rises and presses against the sealing portion 222, the sliding movement between the second guide surface 21131 and the third guide surface 22263 allows the sealing portion 222 to smoothly move closer to the mounting portion 221.

[0094] Similarly, the second guide surface 21131 and the third guide surface 22263 are independently adjusted and configured according to actual needs, including but not limited to being a flat surface or a curved surface.

[0095] See also Figure 2 、 Figure 3 、 Figure 5 and Figure 6 In one specific embodiment, when the sealing strip 22 is in a compressed state, that is, when the glass 10 is in the closed position (i.e., when the glass 10 is raised to the top), the sealing portion 222 abuts against the mounting portion 221 to maintain its position. Specifically, the glass 10 presses against the sealing portion 222, causing the free end to enter the positioning recess 2214 and abut against it. Furthermore, the end of the second flange 2113 abuts the connection between the support arm 22261 and the abutting arm 22262. A fourth guide surface 22264 is provided at the connection between the support arm 22261 and the abutting arm 22262. When the sealing strip 22 switches between the natural and compressed states, the fourth guide surface 22264 slides against the end surface of the second 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 can be configured as an arcuate surface. In addition, a fifth guide surface 22265 is provided on the side of the abutting arm 22262 facing away from the supporting arm 22261. The fifth guide surface 22265 slidably engages with the top end surface 13 of the glass 10. Thus, when the door is opened, the top end surface 13 of the glass 10 presses against the abutting arm 22262 and slides relative to the fifth guide surface 22265. When the abutting arm 22262 is pressed by the glass 10, the fourth guide surface 22264 slides relative to the end surface of the second 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 second 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 second 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 first guide surface 22251, the second guide surface 21131, and the third 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 fourth guide surface 22264 and the fifth guide surface 22265 ensures smooth opening and closing of the frameless door.

[0097] The abutment arm 22262, the support arm 22261, and the first main structure 2227 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 guidance and sliding during the opening and closing of the frameless door.

[0098] See also Figure 2 and Figure 3 For example, a second sealing structure 2228 is provided on the side of the sealing portion 222 facing away from the mounting portion 221. When the sealing strip 22 is in a compressed state, the second sealing structure 2228 is configured to seal and abut against the inner side surface 12 of the glass 10. Thus, when the frameless door is closed, the sealing portion 222 seals and abuts against the top end surface 13 of the glass 10 while the second sealing structure 2228 seals and abuts against the inner side surface 12 of the glass 10, thereby achieving a better sealing effect.

[0099] Furthermore, the first sealing structure 2226 is in sealing contact with the top end face 13 of the glass 10, and the second sealing structure 2228 is in sealing contact with the inner side face 12 of the glass 10, thereby achieving double sealing and greatly improving the sealing performance.

[0100] For example, the second sealing structure 2228 includes at least two protrusions 22281, which are arranged in sequence and spaced apart along the lifting direction of the glass 10, and at least two protrusions 22281 are in sealing contact with the inner side surface 12 of the glass 10. In this way, the second sealing structure 2228 is tightly fitted with the inner side surface 12 of the glass 10 while reducing the contact area, thereby effectively reducing the friction noise between the inner side surface 12 of the glass 10. In addition, the at least two protrusions 22281 and the inner side surface 12 of the glass 10 have at least two layers of sealing, which improves the sealing performance. In addition, the second sealing structure 2228 is provided in the sealing portion 222 and does not need to be separately installed on the body sheet metal, making the structure simple, stable and reliable.

[0101] Specifically, the second sealing structure 2228 is extended along the length direction of the sealing strip 22. More specifically, the protrusion 22281 is extended along the length direction of the sealing strip 22. The protrusion 22281 extends from one end of the sealing strip 22 to the other end of the sealing strip 22.

[0102] In summary, the vehicle door sealing assembly 20 and the vehicle according to an embodiment of the present application have at least the following advantages:

[0103] 1. Non-destructive power-off escape: After the glass short-drop system is removed, 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;

[0104] 2. Vehicle lightweighting: By eliminating the glass drop system, the vehicle's weight is effectively reduced, thereby improving the vehicle's energy efficiency;

[0105] 3. Reduce safety costs: The reduction in vehicle weight reduces the performance requirements for components such as the brake system, thereby reducing related costs;

[0106] 4. 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;

[0107] 5. Improved sealing and quietness: Thanks to the structural stability, reliability and double sealing design, the vehicle's overall sealing is greatly improved, and the quietness of the cabin is also enhanced;

[0108] 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.

It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application.
