[0051] As consumers' aesthetic requirements for car appearance increase, smoother and simpler body lines are gradually becoming more popular.

[0052] In traditional car door designs, the door glass is fitted within the door window frame sheet metal and door trim panel, with the outer surface of the glass lower than the sheet metal and trim panel surfaces, creating a noticeable step difference. This design affects the overall harmony of the vehicle's appearance, and at high speeds, the step area will cause airflow separation, generating vortices, leading to increased wind noise, affecting the comfort of passengers, and also increasing the vehicle's drag coefficient, thus increasing energy consumption.

[0053] Zero-face-difference door technology can improve the aforementioned problems by making the door glass surface flush with the side trim panels. However, existing zero-face-difference door technologies often fail to achieve a flush fit between the glass and the trim panels while ensuring smooth glass operation. In existing technologies, the cooperation between the glass lifting mechanism and the pillar trim panels often suffers from high frictional resistance and unstable operation, affecting the user experience.

[0054] In view of this, the present application provides a glass assembly, a car door, and a vehicle. The glass body slides in contact with the side pillar trim panels via a front lifting auxiliary component and a rear lifting auxiliary component. The split design of the front and rear lifting auxiliary components disperses the contact stress between the glass body and the first and second pillar trim panels, achieving low-friction lifting movement of the glass body and ensuring smooth lifting. In addition, the outer surface of the glass body is flush with the outer surfaces of the first and second pillar trim panels, eliminating the conditions for air turbulence generation, reducing wind noise, improving passenger comfort, and enhancing the vehicle's appearance quality. Furthermore, it reduces the vehicle's drag coefficient, minimizing unnecessary energy consumption that may result from wind resistance.

[0055] refer to Figures 1 to 8 On the one hand, this application provides a glass assembly for a vehicle. Optionally, the vehicle may be a large car, a small car, a special vehicle, etc. The vehicle includes a first pillar trim panel and a second pillar trim panel located on both sides of the glass assembly along the length of the vehicle. The glass assembly includes a glass body 100, a front lifting auxiliary component 200 and a rear lifting auxiliary component 300.

[0056] Optionally, in some embodiments, both the first pillar trim panel and the second pillar trim panel may have a mating stop that mates with the glass body 100, and a sealing element may be designed at the mating stop. The sealing element is adapted to mate with the glass body 100 to fill the mating gap.

[0057] Optionally, the vehicle includes a lifting drive mechanism, which is connected to the glass body 100 in a transmission manner and is suitable for driving the glass body 100 to lift.

[0058] refer to Figure 1 The glass body 100 has an inner surface 100a facing the interior of the vehicle. The inner surface 100a includes a front side 100b and a rear side 100c that are opposite each other along the length of the vehicle. A front lifting assist 200 is connected to the front side 100b and is used to slide with a first pillar trim panel. A rear lifting assist 300 is connected to the rear side 100c and is used to slide with a second pillar trim panel.

[0059] Furthermore, the outer surface of the glass body 100 is on the same plane as the outer surfaces of the first and second pillar trim panels. Optionally, achieving the flushness between the outer surface of the glass body 100 and the outer surfaces of the first and second pillar trim panels can rely on the thickness compensation design of the front lifting auxiliary component 200 and the rear lifting auxiliary component 300, whose installation positions ensure that the outer surface of the glass body 100 is flush with the surfaces of the first and second pillar trim panels after it is raised.

[0060] In the above, the front lifting auxiliary component 200 is a guide component installed on the front side edge 100b of the glass. Specifically, it can be made of plastic. Optionally, the front lifting auxiliary component 200 is injection molded, and its inner side is provided with a sliding contact surface to form line contact or point contact with the first pillar trim panel.

[0061] The rear lifting auxiliary component 300 is a guide component installed on the rear side edge 100c of the glass. It can be made of plastic. Optionally, the rear lifting auxiliary component 300 is injection molded, and its inner side is provided with a sliding contact surface to form line contact or point contact with the second pillar trim panel.

[0062] The separate design of the front lifting auxiliary component 200 and the rear lifting auxiliary component 300 allows them to independently adapt to the assembly tolerances of the first and second pillar trim panels. Optionally, the sliding engagement between the front lifting auxiliary component 200 and the rear lifting auxiliary component 300 and the first and second pillar trim panels, respectively, can be achieved by designing protrusions or roller structures, so that rolling friction or low-friction coefficient sliding friction is formed between the front lifting auxiliary component 200 and the first pillar trim panel, and between the rear lifting auxiliary component 300 and the second trim panel.

[0063] Optionally, both the front lifting auxiliary component 200 and the rear lifting auxiliary component 300 can be designed with a protruding structure facing the first pillar trim panel or the second pillar trim panel. The protruding structure contacts the first pillar trim panel or the second pillar trim panel to achieve a low-friction relative movement.

[0064] Specifically, the glass body 100 is slidably connected to the first pillar trim panel and the second pillar trim panel through the front lifting auxiliary component 200 and the rear lifting auxiliary component 300, respectively. When the lifting drive mechanism drives the glass to move up and down, the front lifting auxiliary component 200 slides along the guide surface on the inner side of the first pillar trim panel, and the rear lifting auxiliary component 300 slides along the guide surface on the inner side of the second pillar trim panel.

[0065] Thus, the glass body 100 slides with the side pillar trim panels via the front lifting auxiliary component 200 and the rear lifting auxiliary component 300, respectively. The split design of the front lifting auxiliary component 200 and the rear lifting auxiliary component 300 disperses the contact stress between the glass body 100 and the first and second pillar trim panels, achieving low-friction lifting movement of the glass body 100 and ensuring smooth lifting. In addition, the outer surface of the glass body 100 is flush with the outer surfaces of the first and second pillar trim panels, eliminating the conditions for air vortex generation, reducing wind noise, improving passenger comfort, and enhancing the vehicle's appearance quality. Furthermore, it reduces the vehicle's drag coefficient, minimizing unnecessary energy consumption that may result from wind resistance.

[0066] In some embodiments, combined with Figure 1 and Figure 2 The front lifting auxiliary component 200 includes a first connecting part 210 that is fitted to the front side edge 100b of the glass body 100. The first lifting mating part 220 is located on the front side of the first connecting part 210 along the length direction of the vehicle. Along the width direction of the vehicle, the first lifting mating part 220 is located on the inner side of the first connecting part 210, so that a first step structure 200a is formed between the first connecting part 210 and the first lifting mating part 220. The first lifting mating part 220 is located on the inner side of the first pillar trim panel and slides in cooperation with the first pillar trim panel.

[0067] The first connecting part 210 is the support component that directly contacts the front side 100b, and can be made of metal or engineering plastic. The first connecting part 210 is used to transmit the load during the lifting and lowering process of the glass body 100. The first lifting mating part 220 is a component that can make sliding contact with the first column trim panel. Optionally, the first lifting mating part 220 can be coated with a wear-resistant coating or inlaid with a low-friction material to reduce relative motion resistance.

[0068] It is understood that the first step structure 200a is a stepped transition area formed by the misalignment of the first connecting part 210 and the first mating part in the width direction. Optionally, the first step structure 200a can be a stepped structure or a staggered structure, used to limit the lifting trajectory and disperse contact stress. In addition, the stepped design of the front lifting auxiliary part 200 realizes the spatial difference between the first connecting part 210 and the first lifting mating part 220, so that the front lifting auxiliary part 200 can achieve the outer surface of the glass body 100 and the outer surface of the first pillar trim while ensuring the sliding fit with the first pillar trim.

[0069] Specifically, the first connecting part 210 is fixed to the front side 100b of the glass body 100 by adhesive bonding to ensure connection stability; the first lifting mating part 220 is arranged inwardly so that it only contacts the first column trim panel in the inner area. When the glass is raised or lowered, the first step structure 200a makes the first column trim panel and the lifting auxiliary component form a one-sided sliding contact. The sliding contact surface is limited to the inner area of ​​the first lifting mating part 220, resulting in a small contact area. In addition, the first step structure 200a also provides a guide reference for the raising and lowering of the glass body 100.

[0070] In this way, by designing the first step structure 200a, the sliding contact area is limited to a single side, reducing lifting resistance and vibration noise, avoiding abnormal wear between the glass body 100 and the first column trim panel. The guiding effect of the first step structure 200a also prevents the lifting trajectory of the glass body 100 from deviating, ensuring that the outer surface of the glass and the plane of the first column trim panel remain flush, maintaining the stability of the zero surface difference design.

[0071] In some embodiments, combined with Figure 4 and Figure 5 The first lifting mating part 220 has a plurality of first protruding structures 230 arranged at intervals along the vehicle height direction on the side surface facing the first pillar trim panel. The first protruding structures 230 extend along the vehicle height direction, and the side surface of the first protruding structure 230 facing the first pillar trim panel is formed as an outwardly convex arc surface. When the glass assembly moves up and down, the first protruding structure 230 contacts and slides with the side surface of the first pillar trim panel facing the interior of the vehicle.

[0072] The first protruding structure 230 can be a strip-shaped protrusion arranged at intervals along the vehicle height direction, and can be realized by injection molding or stamping. The outwardly convex arc surface of the first protruding structure 230 can reduce the contact area with the pillar trim panel. The contact surface of the first protruding structure 230 is an outwardly curved arc, which can be a continuous and smooth curved surface. This arc surface can disperse contact pressure and reduce sliding friction.

[0073] Specifically, the first protruding structures 230 are evenly distributed along the lifting direction of the glass body 100. During the lifting process of the glass body 100, the curved surface forms point contact or line contact with the surface of the column panel. The curved surface design of the first protruding structures 230 makes the stress distribution in the contact area more uniform, thereby reducing frictional resistance. In addition, the spaced first protruding structures 230 allow the glass assembly to produce slight displacements when subjected to thermal expansion or mechanical vibration, avoiding jamming that may occur due to rigid contact.

[0074] By designing a first protruding structure 230 with an outwardly convex arc surface, sliding contact is transformed into local dynamic contact, reducing the motion resistance of the first lifting mating part 220. Furthermore, the arc surface disperses vibration energy, suppressing noise generation. This achieves a low-resistance sliding fit between the glass body 100 and the first pillar trim panel during lifting, ensuring that the outer surface of the glass body 100 remains flush with the outer surface of the pillar trim panel. It also reduces abnormal noises and wear caused by friction, improving the reliability and service life of the zero-face difference door system.

[0075] In some embodiments, combined with Figure 2 The first connecting part 210 has an adhesive groove 211 on the side surface facing the glass body 100. The adhesive groove 211 is used to fill the adhesive, and the glass body 100 and the first connecting part 210 are bonded together by the adhesive.

[0076] Optionally, the adhesive groove 211 can be a continuous groove with a rectangular or trapezoidal cross-section to accommodate the adhesive and increase the bonding area. Optionally, the adhesive can be polyurethane adhesive, silicone adhesive, etc., and a continuous adhesive layer is formed by filling the adhesive groove 211 to achieve a fixed connection between the glass body 100 and the first connecting part 210.

[0077] The adhesive groove 211 extends continuously along the contact edge between the first connecting portion 210 and the glass body 100. In actual operation, the depth and width of the adhesive groove 211 can be selectively designed according to the size of the glass body 100 and the load requirements. Specifically, the adhesive can be injected into the adhesive groove 211 in liquid form and then cured to form a uniform adhesive layer. During the glass assembly process, the first connecting portion 210 is bonded to the glass body 100 by the cured adhesive. In addition, the structure of the adhesive groove 211 keeps the adhesive layer thickness uniform and avoids local stress concentration.

[0078] The design of the adhesive groove 211 and the connecting adhesive enables a seamless connection between the glass body 100 and the first connecting part 210, keeping the outer surface of the glass body 100 flush with the first column trim. The adhesive connection method also reduces the overall weight of the glass assembly and simplifies the assembly process. The structure of the adhesive groove 211 also enhances the shear resistance of the adhesive layer, ensuring that the connection structure of the glass body 100 is stable and reliable during the lifting and lowering process.

[0079] In some embodiments, combined with Figures 6 to 8 The rear lifting auxiliary component 300 includes a second connecting portion 310, which is fitted to the rear side 100c; and a second lifting mating portion 320, which is located on the rear side of the second connecting portion 310 along the length direction of the vehicle and on the inner side of the second connecting portion 310 along the width direction of the vehicle, so that a second step structure 300a is formed between the second connecting portion 310 and the second lifting mating portion 320. The second lifting mating portion 320 is located on the inner side of the second pillar trim panel and slides in cooperation with the second pillar trim panel.

[0080] Optionally, the second connecting part 310 can be fixed to the rear side 100c by adhesive. The second connecting part 310 can also be designed with an adhesive groove 211, which is filled with connecting adhesive to fix the second connecting part 310 and the rear side 100c. Optionally, the second lifting mating part 320 can be implemented by setting a protruding structure or a guide groove to achieve a sliding fit with the second column trim panel.

[0081] It is understood that the second step structure 300a is a stepped transition area formed by the misalignment of the second connecting part 310 and the second mating part in the width direction. Optionally, the second step structure 300a can be a stepped structure or a staggered structure, used to limit the lifting trajectory and disperse contact stress. In addition, the stepped design of the rear lifting auxiliary part 300 realizes the spatial difference between the second connecting part 310 and the second lifting mating part 320, so that the rear lifting auxiliary part 300 can achieve the outer surface of the glass body 100 and the outer surface of the second pillar trim while ensuring the sliding fit with the second pillar trim.

[0082] Specifically, the second connecting part 310 can be fixed to the rear side 100c of the glass body 100 by adhesive bonding to ensure connection stability. The second lifting mating part 320 is located behind the second connecting part 310 and offset inward to form a second step structure 300a, so that the second lifting mating part 320 contacts and slides against the inner surface of the second column trim during lifting. This design reduces lifting resistance by reducing the contact area and introducing a stepped transition, and also avoids misalignment between the outer surface of the glass body 100 and the second column trim, thereby maintaining the outer surface flush.

[0083] By designing the second step structure 300a, the sliding contact area is limited to a local area between the second lifting mating part 320 and the inner side of the second pillar trim panel, which optimizes the force distribution. The misalignment design also compensates for the assembly tolerance, ensuring that the glass body 100 can be lifted and lowered smoothly, and that the outer surface of the glass body 100 is always aligned with the outer surface of the second pillar trim panel, thereby reducing wind resistance and wind noise during vehicle movement.

[0084] In some embodiments, combined with Figure 6and Figure 7 The second pillar trim panel includes a first surface facing the interior of the vehicle along the width direction and a second surface facing forward along the length direction of the vehicle; the second lifting mating part 320 includes a first side surface 320a opposite to the first surface and a second side surface 320b opposite to the second surface. The first side surface 320a is provided with a plurality of second protrusion structures 330 arranged at intervals along the height direction of the vehicle. The second protrusion structures 330 extend along the height direction of the vehicle, and the side surface of the second protrusion structure 330 facing the first surface is formed as an outwardly convex arc surface.

[0085] The second side 320b is provided with a plurality of third protrusions 340 arranged at intervals along the vehicle height direction. The third protrusions 340 extend along the vehicle height direction, and the side surface of the third protrusions 340 facing the second surface is formed as an outwardly convex arc surface. When the glass body 100 moves up and down, the second protrusions 330 contacts and slides with the first surface, and the third protrusions 340 contacts and slides with the second surface.

[0086] The second protruding structure 330 is a longitudinally extending protrusion provided along the first side 320a of the second lifting mating part 320. Optionally, the second protruding structure 330 can be integrally formed with the second lifting mating part 320 by injection molding process. The outer convex arc surface of the second protruding structure 330 can reduce the contact area with the first surface of the second column trim.

[0087] The third protrusion structure 340 is a longitudinally extending protrusion provided along the second side 320b of the second lifting mating part 320. Optionally, the third protrusion structure 340 can also be integrally formed with the second lifting mating part 320 by injection molding process. The outer convex arc surface of the third protrusion structure 340 can disperse pressure during sliding contact.

[0088] It is understood that the first surface and the second surface are the inner sidewall and the front sidewall of the second column panel, respectively. The second protruding structure 330 and the third protruding structure 340 can slide and cooperate with the first surface and the second surface to achieve multi-directional limiting of the glass assembly during the lifting process.

[0089] Specifically, the second lifting mating part 320 forms sliding contact with the first surface and the second surface of the second column trim panel through the first side 320a and the second side 320b respectively. The second protruding structure 330 is longitudinally distributed along the first side 320a, and its outer convex arc surface makes point contact or surface contact with the first surface. The third protruding structure 340 is longitudinally distributed along the second side 320b, and its outer convex arc surface makes point contact or surface contact with the second surface, thereby reducing frictional resistance.

[0090] During the lifting and lowering of the glass body 100, the second protruding structure 330 maintains a sliding fit with the first surface, and the third protruding structure 340 slides synchronously with the second surface to form a double guide structure, which avoids possible displacement or shaking of the glass assembly during the lifting and lowering process.

[0091] By providing a second protruding structure 330 and a third protruding structure 340 with outwardly convex arc surfaces on the first side 320a and the second side 320b of the second lifting mating part 320, the sliding contact in the conventional technology is designed as multi-point or multi-faceted line contact, reducing the coefficient of friction and dispersing contact stress to avoid localized wear. This achieves bidirectional sliding limit of the glass assembly in the area of ​​the second pillar trim panel, improving the sliding stability of the second lifting mating part 320. The outwardly convex arc surface design also reduces lifting resistance, extends the service life of the second lifting mating structure, and ensures the smooth lifting of the zero-face difference door glass.

[0092] In some embodiments, combined with Figure 6 and Figure 8 A fourth protrusion structure 350 is also provided on the first side surface 320a. At least a portion of the structure of the fourth protrusion structure 350 facing the first surface is formed as a plane. A buffer gap is formed between the fourth protrusion structure 350 and the first surface, and the width of the buffer gap is 0.3mm-0.7mm.

[0093] Optionally, the width of the buffer gap can be 0.3mm, 0.4mm, 0.5mm, 0.58mm, 0.6mm, 0.7mm, etc. In a preferred embodiment, the width of the buffer gap can be 0.5mm.

[0094] In this embodiment, at least a portion of the fourth protrusion structure 350 facing the first surface is planar. Optionally, the fourth protrusion structure 350 may be integrally formed with the second lifting mating part 320 by injection molding.

[0095] The buffer gap is a reserved space between the fourth protrusion 350 and the first surface, used to absorb minor displacement deviations generated during the lifting and lowering of the glass body 100, and to avoid vibration transmission caused by rigid contact. The width range of the buffer gap is the dimension of the gap in the vehicle width direction. This range ensures the compensation effect of the buffer gap on displacement deviations and also avoids the decrease in fit stability that may be caused by an excessively large gap.

[0096] Optional, refer to Figure 8The fourth protruding structure 350 may include a fixing part 351 and a protruding part 352. The fixing part 351 is fixed to the first side surface 320a. The protruding part 352 is provided on the side surface of the fixing part 351 facing the first surface. The protruding part 352 protrudes from the fixing part 351. The side of the protruding part 352 facing the first surface has an abutting plane 3521. The end connecting part of the abutting plane 3521 has an arc-shaped connecting surface 3522. The arc-shaped connecting surface 3522 is connected to the fixing part 351. The arc-shaped connecting surface 3522 protrudes towards the first surface. Referring to the fixing part 351, the highest point of the arc-shaped connecting surface 3522 facing the first surface is lower than the abutting plane 3521.

[0097] Specifically, during the lifting and lowering of the glass assembly, the second lifting mating part 320 slides in contact with the first surface via the second protruding structure 330, while the planar portion of the fourth protruding structure 350 maintains a fixed gap with the first surface. When the glass assembly experiences a slight displacement, the buffer gap allows the fourth protruding structure 350 to move freely without contacting the first surface, thereby preventing the contact plane 3521 from contacting the glass body 100 and generating frictional resistance. When the displacement exceeds the gap width, the contact plane 3521 of the fourth protruding structure 350 contacts the first surface to form auxiliary support, preventing excessive shaking of the glass assembly.

[0098] By setting a fourth protrusion structure 350 with a buffer gap, the stability advantage of planar contact is retained, and the friction loss caused by continuous contact is eliminated through the gap design. In this way, the fluctuation of operating resistance that may be caused by assembly errors or changes in ambient temperature during the lifting and lowering of the glass body 100 is reduced, and the jamming phenomenon caused by friction in the planar contact structure during long-term use is avoided. In addition, the synergistic effect of the buffer gap and the planar contact improves the smoothness and durability of the lifting and lowering movement of the glass body 100.

[0099] In some embodiments, combined with Figure 3 The glass assembly also includes a base bracket 400, which is connected to the bottom of the glass body 100 and is used to connect the lifting drive mechanism.

[0100] Optionally, the base bracket 400 can be made of metal stamping or high-strength plastic. The optional base bracket 400 can be fixedly connected to the bottom of the glass body 100 by adhesive bonding to achieve rigid support for the lifting and lowering movement of the glass body 100.

[0101] In some examples, combined Figure 3 The base bracket 400 has an installation groove 410 for inserting the glass body 100 and for holding adhesive to achieve bonding and fixing with the glass body 100.

[0102] Optionally, the lifting drive mechanism can be a motor-driven rack and pinion mechanism or a wire rope pulley mechanism, which forms a transmission connection with the glass body 100 through the base bracket 400, thereby transmitting the driving force to the glass body 100.

[0103] Specifically, the base bracket 400 is fixed to the bottom of the glass body 100, and the lifting drive mechanism is linked with the glass body 100 through the base bracket 400. When the drive mechanism is running, the base bracket 400 drives the glass body 100 to move vertically along the window lifting opening.

[0104] By designing the base bracket 400 as the connection structure between the glass body 100 and the lifting drive structure, the structural strength of the glass body 100 is ensured, and the driving force is distributed more evenly, reducing the frictional resistance and abnormal noise during the lifting process of the glass body 100. In this way, the glass assembly can move smoothly during the lifting process, reducing the wear of sliding parts that may be caused by uneven force. In addition, the firm connection between the base bracket 400 and the drive mechanism ensures that the outer surface of the glass body 100 and the outer surface of the column panel are always on the same plane, maintaining the integrity of the zero surface difference design and reducing wind resistance and wind noise.

[0105] Secondly, this application embodiment also provides a vehicle door, including a vehicle door sheet metal, a lifting drive mechanism and the aforementioned glass assembly. The vehicle door sheet metal defines a vehicle window, and a storage cavity is provided on the inner side of the vehicle door sheet metal. The top of the storage cavity has a lifting port that connects the vehicle window and the storage cavity. The glass body 100 moves up and down between the vehicle window and the storage cavity via the lifting port. The lifting drive mechanism is connected to the glass body 100 to drive the glass body 100 to move up and down.

[0106] Optionally, the door sheet metal can be manufactured using a stamping process to form window openings and interior storage space.

[0107] The storage cavity can be used to store the glass assembly in the lowered state, and the lifting port can be used to guide the lifting path of the glass body 100. Optionally, the lifting drive mechanism can be a motor-driven rack and pinion mechanism or a wire rope pulley mechanism, which forms a transmission connection with the glass body 100 through the base bracket 400, thereby transmitting the driving force to the glass body 100.

[0108] Specifically, the glass assembly is installed on the inner side of the door sheet metal, and its glass body 100 moves vertically along the lifting opening under the action of the lifting drive mechanism. When the glass body 100 is raised, the outer surface of the glass body 100 remains flush with the outer surfaces of the first pillar trim panel and the second pillar trim panel, forming a continuous plane. During the lifting process, the front lifting auxiliary component 200 and the rear lifting auxiliary component 300 slide in contact with the first pillar trim panel and the second pillar trim panel, respectively, to reduce movement resistance.

[0109] Optionally, in some examples, the sidewall of the storage cavity may be provided with a guide groove, which may cooperate with the first protrusion structure 230 and the second protrusion structure 330 to enhance lifting stability.

[0110] Optionally, the edge of the lifting port can be covered with a flexible sealing strip to prevent foreign objects from entering the storage cavity.

[0111] The car door mentioned in this application embodiment, by designing the above-mentioned glass components, achieves zero surface difference fit between the outer surface of the glass body 100 and the body trim panel during the lifting and lowering process, effectively reducing air resistance and wind noise when the vehicle is driving. The sliding fit structure between the glass components and the first pillar trim panel and the second pillar trim panel reduces the lifting resistance, ensures smooth operation, and achieves the reliability of the car door.

[0112] Thirdly, this application also provides a vehicle. In this embodiment, the vehicle can refer to a large car, a small car, a special-purpose vehicle, etc. For example, according to the power type, the vehicle in this application can be a pure electric vehicle, a hybrid electric vehicle, a fuel vehicle, etc. For fuel vehicles, the power source can refer to a gasoline engine, a diesel engine, or other fuel engines; for electric vehicles, the power source can refer to an electric motor; for hybrid electric vehicles, the power source can refer to an engine or an electric motor; for vehicles powered by other means, the power source can refer to the equipment that generates power. According to the vehicle type, the vehicle in this application can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles.

[0113] The vehicle includes doors and a body. The doors are closable and located at the frame. The frame includes a first pillar trim panel and a second pillar trim panel located on both sides of the doors along the length of the vehicle. When the glass body 100 is raised, the outer surface of the glass body 100 is on the same plane as the outer surfaces of the first pillar trim panel and the second pillar trim panel.

[0114] Optionally, in some embodiments, both the first pillar trim panel and the second pillar trim panel may have a mating stop that mates with the glass body 100, and a sealing element may be designed at the mating stop. The sealing element is adapted to mate with the glass body 100 to fill the mating gap.

[0115] The vehicle mentioned in this application embodiment, by designing the aforementioned door, ensures the smoothness of the glass body 100's lifting and lowering process. In addition, the outer surface of the glass body 100 is flush with the outer surfaces of the first pillar trim panel and the second pillar trim panel, reducing the vortex generated by the side airflow separation when the vehicle is driving, reducing air resistance and noise, lowering the vehicle's drag coefficient, and reducing the vehicle's energy consumption. Furthermore, the zero-surface-difference door design also improves the vehicle's appearance quality and enhances its market competitiveness.
