Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and more specifically to a door frame, a door assembly having the door frame, and a vehicle. Background Technology

[0002] In related technologies, the door assembly includes a window glass component, sealing strip, door frame, and guide rail. In the area that mates with the window glass component, a portion of the window frame, the guide rail, and the pillar trim are sequentially arranged in the inward and outward directions of the vehicle. The guide rail extends along the height of the door frame to a height corresponding to the window opening of the window frame to guide and limit the movement of the window glass component. The upper end of the guide rail connects to the area of ​​the door frame near the top of the vehicle. During assembly and long-term use, the upper end of the guide rail is prone to significant bulging and deformation, creating a noticeable step difference between the upper end of the guide rail and the door frame. Furthermore, replacing the window glass component requires removing the guide rail, which presents an inconvenience. Summary of the Invention

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention disclose a car door frame. This car door frame has the advantages of easy disassembly and, moreover, avoids the problem of a significant step difference between the upper end of the guide rail and the frame body due to excessively long guide rails, which affects the smoothness of the car window glass assembly.

[0004] An embodiment of the present invention also discloses a door assembly.

[0005] An embodiment of the present invention also discloses a vehicle.

[0006] The door frame of this invention includes a frame body and a first guide rail.

[0007] The frame body has a first sub-guide groove extending along the height direction of the vehicle. The first guide rail is located below the first sub-guide groove. The first guide rail is provided with a second sub-guide groove. The first sub-guide groove and the second sub-guide groove are connected and form a guide groove for sliding cooperation with the window glass assembly.

[0008] In this embodiment of the invention, the door frame has a first sub-guide groove formed on the frame body to guide and cooperate with the window glass assembly, replacing the guide rail section in that area. It is understood that forming the first sub-guide groove on the frame body reduces the extension length of the first guide rail. Therefore, it avoids the problem of jamming when the window glass assembly moves due to the step difference between the upper end of the guide rail and the door frame.

[0009] Furthermore, when the first guide rail malfunctions, existing technologies require disassembling the entire guide rail area and the window glass assembly for replacement, which is inconvenient. However, this application allows for guide rail replacement by simply raising the window to the closed position, disassembling and replacing the first guide rail, without needing to remove the window glass assembly. This significantly improves the ease of guide rail replacement.

[0010] Therefore, the door frame of the present invention has the advantages of avoiding a significant step difference between the upper end of the guide rail and the door frame due to the excessive length of the guide rail, which would affect the smoothness of the window glass assembly and improve the ease of disassembly of the guide rail.

[0057] Embodiments of the present invention are described in detail below, with examples of the embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0058] The following is for reference. Figures 1-12 The present invention describes a door frame 100, a door assembly having the door frame 100, and a vehicle.

[0059] The door frame 100 of this invention includes a frame body and a first guide rail 3.

[0060] The frame body has a first sub-guide groove 21 extending along the height direction of the vehicle. A first guide rail 3 is located below the first sub-guide groove 21. The first guide rail 3 has a second sub-guide groove 31, and the first sub-guide groove 21 and the second sub-guide groove 31 are connected to form a guide groove for sliding engagement with the window glass assembly. It can be understood that the first sub-guide groove 21 and the second sub-guide groove 31 are arranged opposite to each other and connected in the height direction of the vehicle so that the window glass assembly 200 can move smoothly along the first sub-guide groove 21 and the second sub-guide groove 31.

[0061] In this embodiment of the invention, the door frame 100 replaces the guide rail section in this area by forming a first sub-guide groove 21 on the frame body that can guide and cooperate with the window glass assembly. It can be understood that forming the first sub-guide groove 21 on the frame body can reduce the extension length of the first guide rail 3. As a result, the problem of jamming when the window glass assembly 200 moves due to the step difference between the upper end of the guide rail and the door frame can be avoided.

[0062] Furthermore, when the first guide rail malfunctions, the existing technology requires disassembling the entire guide rail area and the window glass assembly 200 for replacement, which is inconvenient. However, this application allows for guide rail replacement by raising the window to the closed position, disassembling and replacing the first guide rail, without needing to remove the window glass assembly. This significantly improves the ease of guide rail replacement.

[0063] Therefore, the door frame 100 of this embodiment avoids the problem that the upper end of the guide rail and the door frame 100 are obviously stepped due to the excessive length of the guide rail, which affects the smoothness of the window glass assembly 200, and also improves the ease of disassembling the guide rail.

[0064] like Figure 1 and Figure 2As shown, the frame body includes a window frame and a first pillar trim 2. The first pillar trim 2 extends along the height direction of the vehicle and is located above the first guide rail 3. The first pillar trim 2 and at least a portion of the window frame 1 form a first sub-guide groove 21 extending along the height direction of the vehicle.

[0065] In this embodiment of the invention, the door frame 100 uses a first sub-guide groove 21 formed by the first pillar trim panel 2 and the window frame 1 itself (the first sub-guide groove 21 can guide and cooperate with the window glass assembly 200) to replace the guide rail in that area, thus reducing the extension length of the first guide rail 3. Therefore, it is beneficial to control the production cost of the door frame 100 and reduce its overall weight. This results in the advantage of reducing the production cost and weight of the door frame 100.

[0066] Furthermore, by forming a first sub-guide groove 21 with the structure of the first pillar trim 2 and the window frame 1, the width space of the vehicle compartment occupied by the first guide rail 3 can be saved. Specifically, without changing the size and position of the first pillar trim 2, at least a portion of the window frame 1 can be made closer to the first pillar trim 2 in the width direction of the vehicle. Thus, it has the advantages of good compactness of the door frame 100 and improved interior space of the vehicle.

[0067] The invention is not limited thereto. In other embodiments, the first pillar trim 2 has a first sub-guide groove 21 extending along the height direction of the vehicle. For example, a guide plate is provided on the side of the first pillar trim 2 closest to the interior of the passenger compartment, and the first sub-guide groove 21 is formed between the guide plate and the first pillar trim 2. This results in the advantages of a compact door frame 100 and increased interior space.

[0068] Optionally, the first pillar trim 2 can be the B-pillar trim of the vehicle.

[0069] like Figure 1 and Figure 2 As shown, one end of the first guide rail 3 (as shown) Figure 1 As shown in the diagram, the upper end of the first guide rail 3 is connected to the lower end of the first column decorative panel 2.

[0070] The door frame 100 of this embodiment of the invention is connected to the first pillar trim 2 by one end of the first guide rail 3, which facilitates further positioning of the relative positions of the first sub-guide groove 21 and the second sub-guide groove 31, and helps to improve the smoothness of the movement of the vehicle window glass assembly 200 in the height direction of the vehicle and the overall structural stability of the door frame 100.

[0071] Optionally, the upper end of the first guide rail 3 is detachably connected to the first pillar trim 2. This improves the ease of installation of the first pillar trim 2 and the first guide rail 3. During assembly, the first guide rail 3 can be installed in the corresponding position first, then the first pillar trim 2 can be connected to the first guide rail 3, and finally the first pillar trim 2 can be installed in the corresponding position on the door frame 100. Since the first pillar trim 2 is located on the outside of the vehicle, installing the first pillar trim 2 later has the advantage of improving installation convenience.

[0072] Furthermore, the first guide rail 3 and the first column decorative panel 2 can be connected by a connecting pin. Specifically, as shown below... Figure 2 and Figure 12 As shown, a connecting pin extending in the vertical direction can be provided at the upper end of the first guide rail 3 and the lower end of the first column decorative panel 2. This provides the advantages of simple structure and convenient installation.

[0073] For example, Figure 12 As shown, the upper end of the first guide rail 3 has an extension 33, which is connected to the first column decorative panel 2 by a connecting pin.

[0074] like Figure 1 and Figure 2 As shown, the door frame 100 also includes a first sub-sealing strip 41, which is disposed within a first sub-guide groove 21. Alternatively, the door frame 100 also includes a second sub-sealing strip 42, which is disposed within a second sub-guide groove 31.

[0075] The door frame 100 of this embodiment of the invention, by providing a first sub-sealing strip 41 in the first sub-guide groove 21 or a second sub-sealing strip 42 in the second sub-guide groove 31, helps to improve the airtightness of the door frame 100 and the window glass assembly 200. Therefore, the door frame 100 of this embodiment of the invention has the advantage of reducing noise inside the vehicle cabin.

[0076] Furthermore, such as Figure 1 and Figure 2 As shown, the door frame 100 also includes a first sub-sealing strip 41 and a second sub-sealing strip 42, with the first sub-sealing strip 41 disposed within the first sub-guide groove 21 and the second sub-sealing strip 42 disposed within the second sub-guide groove 31. It can be understood that the first sub-sealing strip 41 and the second sub-sealing strip 42 are disposed in a one-to-one correspondence within the first sub-guide groove 21 and the second sub-guide groove 31, and the first sub-sealing strip 41 and the second sub-sealing strip 42 are independent of each other.

[0077] In this embodiment of the vehicle door frame 100, by setting corresponding guide groove sealing strip segments in corresponding sub-guide grooves, when assembling the second sub-sealing strip 42, the second sub-sealing strip 42 and the first guide rail 3 can be prefabricated. The second sub-sealing strip 42 is then assembled together with the first guide rail 3 at the position corresponding to the first sub-sealing strip 41, that is, the second sub-sealing strip 42 and the first sub-sealing strip 41 are arranged opposite to and connected along the height direction of the vehicle. In related technologies, when the first sub-sealing strip 41 and the second sub-sealing strip 42 are an integral structure, it is often necessary to first assemble the sealing strip with the area of ​​the first sub-guide groove 21, and then insert the section of the sealing strip that mates with the first guide rail 3 into the second sub-guide groove 31 on the first guide rail 3. Therefore, the vehicle door frame 100 of this embodiment of the invention has the advantages of improving the assembly efficiency and convenience of the second sub-sealing strip 42 and the first guide rail 3.

[0078] like Figure 1 and Figure 3 As shown, the first pillar trim 2 has a first limiting portion on the side near the first sub-guide groove 21 to limit the window glass assembly 200 in the length and width directions of the vehicle. It can be understood that the first limiting portion is located on the side of the first pillar trim 2 closer to the vehicle interior.

[0079] In this embodiment of the invention, the door frame 100, by providing a first limiting part on the side of the first pillar trim 2 near the first sub-guide groove 21, can limit the window glass assembly 200 in the width and length directions of the vehicle. This improves the smoothness of the window glass assembly 200's raising and lowering.

[0080] like Figure 1 and Figure 3 As shown, the first pillar panel 2 includes a first panel body 22, a first stop 23 and a second stop 24. Each of the first stop 23 and the second stop 24 extends from the side of the first panel body 22 near the first sub-guide groove 21 toward the window frame 1. The first stop 23 and the second stop 24 are arranged at intervals to define a first limiting portion.

[0081] The door frame 100 of this embodiment of the invention defines a first limiting portion by dividing the first pillar trim panel 2 into a first trim panel body 22, a first stop portion 23, and a second stop portion 24. Each of the first stop portion 23 and the second stop portion 24 extends from the side of the first trim panel body 22 near the window frame 1 (specifically, each of the first stop portion 23 and the second stop portion 24 extends from the inside of the first trim panel body 22 toward the inside of the vehicle) toward the window frame reinforcing plate 12, and the first limiting portion is defined by the spaced arrangement of the first stop portion 23 and the second stop portion 24. This provides the advantage of a simple structure.

[0082] Optionally, the first trim panel body 22, the first stop 23, and the second stop 24 define a groove-shaped limiting portion (first limiting portion). The first stop 23 and the second stop 24 are arranged in parallel, with the opening of the groove-shaped limiting portion facing the inside of the vehicle, and the groove-shaped limiting portion extending along the height direction of the vehicle. Further, the groove-shaped limiting portion is a U-shaped groove, and the first stop 23 and the second stop 24 are the sidewalls of the U-shaped groove. This further improves the stability and sealing of the first sub-sealing strip 41.

[0083] Optionally, the first sub-seal strip 41 includes a connected first sub-seal strip body 411 and a first lip portion 412, with the first lip portion 412 embedded within the first limiting portion. This further enhances the stability and sealing performance of the first sub-seal strip 41 during installation.

[0084] Optionally, a portion of the first sub-sealing strip 41 is embedded within the first limiting portion. Thus, by embedding a portion (first lip portion 412) of the first sub-sealing strip 41 within the first limiting portion, the first sub-sealing strip 41 can be limited, which has the advantage of improving the stability of the connection between the first sub-sealing strip 41 and the first column trim 2.

[0085] like Figure 1 and Figure 3 As shown, the first stop 23 and the second stop 24 are in the length direction of the vehicle (e.g., Figure 1 As shown in the front-rear direction, the first stop 23 and the second stop 24 are spaced apart and located on the same side of the window 11 of the window frame 1 in the longitudinal direction of the vehicle. It is understood that the first stop 23, the second stop 24 and the first trim panel body 22 can form a groove-shaped receiving structure.

[0086] In this embodiment of the invention, the door frame 100 is spaced apart along the length of the vehicle by a first stop 23 and a second stop 24. The first stop 23 and the second stop 24 are located on the same side of the window 11 of the door frame 100 along the length of the vehicle (e.g., Figure 3 As shown, both the first stop 23 and the second stop 24 are located on the rear side of the window 11. This improves the sealing performance between the first sub-seal strip 41 and the first pillar trim 2. Furthermore, it enhances the stability of the window glass assembly 200 during its lifting and lowering process in the width and length directions of the vehicle.

[0087] For example, Figure 3 As shown, each of the first stop portion 23 and the second stop portion 24 is along the width direction of the vehicle. Figure 3 The left-right direction shown extends from the side of the first trim panel body 22 near the first sub-guide groove 21 toward the direction near the window frame reinforcement plate 12. It can be understood that both the first stop 23 and the second stop 24 extend from the wall of the first trim panel body 22 located inside the vehicle toward the interior of the passenger compartment.

[0088] like Figure 1 and Figure 3 As shown, the first pillar trim panel 2 also includes a third stop 26. The first trim panel body 22 has a wall facing the window 11 of the door frame 100. The third stop 26 is connected to the wall. The first pillar trim panel 2 has a third limiting part, which is provided on the wall. The third limiting part is formed between at least one of the first trim panel body 22 and the first stop 23 and the third stop 26. The first sub-seal strip 41 also includes a second lip 413 connected to the first sub-seal strip body 411. The second lip 413 is provided in the third limiting part.

[0089] The door frame 100 of this embodiment of the invention, through the cooperation between the third limiting portion disposed on the first pillar trim panel 2 and the second lip portion 413 connected to the first sub-sealing strip body 411, can further improve the sealing performance between the first sub-sealing strip 41 and the first pillar trim panel 2. Therefore, the door frame 100 of this embodiment of the invention has the advantage of reducing noise inside the vehicle cabin.

[0090] like Figure 1 and Figure 3 As shown, the first stop 23 is provided on the wall surface, and the free end of the first stop 23 is provided with a protrusion 27 protruding toward the window 11 along the length direction of the vehicle. The first stop 23, the protrusion 27 and the third stop 26 define the third limiting part.

[0091] The door frame 100 of this embodiment of the invention defines a third limiting portion by a first stop portion 23, a protrusion 27, and a third stop portion 26. This allows the second lip portion 413 to be embedded within the third limiting portion, preventing the first sub-sealing strip 41 from moving along the width direction of the vehicle and preventing the first sub-sealing strip 41 from detaching from the third limiting portion. This further improves the structural stability of the door frame 100.

[0092] Optionally, the third limiting part is a U-shaped limiting groove extending along the vehicle height direction.

[0093] like Figure 1 and Figure 4 As shown, a second limiting part 32 is formed on the first guide rail 3 to limit the window glass assembly 200 in the length and width directions of the vehicle.

[0094] The door frame 100 of this embodiment of the invention, through the second limiting portion 32 formed on the first guide rail 3, can further limit the width and length of the window glass assembly 200 in the vehicle direction. This provides the advantage of improving the smoothness of movement of the window glass assembly 200.

[0095] like Figure 1 , Figure 4 and Figure 10As shown, the window frame 1 includes a window frame reinforcing plate 12, at least a portion of which is disposed opposite to the first pillar trim 2 in the inward and outward directions of the vehicle, and a first sub-guide groove 21 is formed between the first pillar trim 2 and at least a portion of the window frame reinforcing plate 12.

[0096] The door frame 100 of this embodiment of the invention has at least a portion of the window frame reinforcing plate 12 located inside the first pillar trim 2, and a first sub-guide groove 21 is formed between the first pillar trim 2 and the at least portion of the window frame reinforcing plate 12, which has the advantage of simple structure.

[0097] Optionally, the window frame reinforcing plate 12 can be a reinforcing sheet metal part. Therefore, the door frame 100 of this embodiment of the invention has the advantage of high structural strength.

[0098] like Figure 1 , Figure 10 and Figure 11 As shown, the first pillar trim panel 2 also includes multiple exterior trim brackets 25. The exterior trim brackets 25 are located between the second stop 24 and the outer edge of the first pillar trim panel 2 on the first trim panel body 22. The multiple exterior trim brackets 25 are arranged on the same side facing the first sub-guide groove 21. The window frame reinforcing plate 12 includes a reinforcing plate body 121 and multiple mating grooves 122. The multiple mating grooves 122 are arranged on the same side facing the first sub-guide groove 21 on the reinforcing plate body 121. The multiple exterior trim brackets 25 are arranged one-to-one in the multiple mating grooves 122. The first sub-guide groove 21 is formed between the reinforcing plate body 121 and the first trim panel body 22.

[0099] The door frame 100 of this embodiment of the invention, through the mutual cooperation between the exterior trim bracket 25 on the first pillar trim panel 2 and the mating groove 122 of the window frame reinforcing plate 12, fixes the first pillar trim panel 2, thereby further improving the stability of the connection between the first pillar trim panel 2 and the window frame reinforcing plate 12. Furthermore, the mutual cooperation between the multiple mating grooves 122 and the exterior trim bracket 25 increases the stability of the exterior trim bracket 25 installation. Therefore, it has the advantage of further improving the stability of the connection between the first pillar trim panel 2 and the window frame reinforcing plate 12.

[0100] Specifically, multiple mating grooves 122 are located along the height direction of the vehicle (e.g., Figure 10 The window frame reinforcing plates 12 are spaced apart in the vertical direction as shown in the diagram.

[0101] Furthermore, the bottom wall of the exterior bracket 25 and the mating groove 122 is secured by a connector (not shown). This further enhances the stability of the connection between the first pillar trim 2 and the window frame reinforcing plate 12. For example, the connector can be a screw, threaded rod, or stud.

[0102] Furthermore, the mating groove 122 and the exterior bracket 25 are fixed by connectors.

[0103] Furthermore, such as Figure 1 and Figure 3 As shown, the outer edge of the first pillar trim 2 has a rolled edge portion 28 that bends toward the first sub-guide groove 21. The first sub-sealing strip 41 has a limiting groove 414. The limiting groove 414 and the rolled edge portion 28 are arranged opposite to each other in the length direction of the vehicle. One end of the window frame reinforcing plate 12 is disposed in the rolled edge portion 28, and the other end of the window frame reinforcing plate 12 is disposed in the limiting groove 414.

[0104] In this embodiment of the invention, the door frame 100 has a rolled edge 28 on the outer edge of the first pillar trim 2 along the length of the vehicle, which bends toward the first sub-guide groove 21. The first sub-sealing strip 41 has a limiting groove 414, which can fix the window frame reinforcing plate 12. This further improves the ease of installation of the window frame reinforcing plate 12 and the overall structural stability of the door frame 100.

[0105] Specifically, the exterior bracket 25 is located in the area between the second stop 24 and the rolled edge 28, or the exterior bracket 25 is connected to the second stop 24. The window frame reinforcing plate 12 includes a reinforcing plate body 121 and a mating groove 122, with the mating groove 122 located on the side of the reinforcing plate body 121 facing the first sub-guide groove 21.

[0106] like Figure 1 and Figure 3 As shown, the window frame 1 has a boss 123 on the side near the first sub-guide groove 21, and a part of the first sub-sealing strip 41 abuts against the boss 123.

[0107] Specifically, a boss 123 is provided on the side of the window frame reinforcing plate 12 near the first sub-guide groove 21, and a part of the guide groove sealing strip abuts against the boss 123.

[0108] In this embodiment of the invention, the door frame 100 has a protrusion 123 on the side of the window frame reinforcing plate 12 near the first sub-guide groove 21. A portion of the first sub-sealing strip 41 abuts against the protrusion 123, thereby limiting the first sub-sealing strip 41 in the width direction of the vehicle. This improves the stability of the first sub-sealing strip 41 installation.

[0109] Furthermore, the boss portion 123 is located in the area between the limiting groove 414 and the first limiting portion of the window frame reinforcing plate 12. The boss portion 123 and the first sub-sealing strip 41 can be further fixed with screws.

[0110] Furthermore, the connector is mounted on the reinforcing plate body 121, and the connector is positioned relative to the boss portion 123 near the interior area of ​​the carriage to avoid interference between the connector and the guide groove sealing strip. The connector can be a screw or a stud.

[0111] like Figure 2 , Figure 6 and Figure 7 As shown, the door frame 100 also includes a second guide rail 5 extending along the height direction of the vehicle. The second guide rail 5 defines a second guide groove 51, which is disposed opposite to each of the first sub-guide groove 21 and the second sub-guide groove 31 in the length direction of the vehicle. For example, Figure 1 and Figure 2 As shown, the opening of the second guide groove 51 is arranged facing rearward, and the openings of each of the first sub-guide groove 21 and the second sub-guide groove 31 are arranged facing forward.

[0112] The door frame 100 of this embodiment of the invention, by setting a second guide rail 5 and a second guide groove 51 defined by the second guide rail 5, and the window glass assembly 200 by the first pillar trim 2, the first guide rail 3, the first guide rail 3 and the second guide rail 5, limits the front-to-back direction and the width direction of the vehicle, thereby improving the stability of the installation of the window glass assembly 200.

[0113] like Figure 2 , Figure 6 and Figure 7 As shown, the door frame 100 of this embodiment of the invention also includes a second pillar trim 6 extending along the height direction of the vehicle. The second guide groove 51 includes a first guide groove section 511 and a second guide groove section 512. The first guide groove section is opposite to the first sub-guide groove 21, and the second guide groove section 512 is opposite to the second sub-guide groove 31. The first guide groove section 511 is connected to the inner wall of the second pillar trim 6.

[0114] The door frame 100 of this invention includes a first guide groove section 511 and a second guide groove section 512 via a second guide groove 51. The first guide groove section 511 is connected to the inner wall of the second pillar trim panel 6, which can further limit the position of the window glass assembly 200, effectively reducing the amount of shaking when the door is closed. It has the advantages of improving the ease of installation of the first guide groove section 511 and the smoothness of the lifting and lowering of the window glass assembly 200.

[0115] Optionally, the second pillar trim 6 can be the A-pillar trim of the front door or the C-pillar trim of the rear door.

[0116] like Figure 2 , Figure 6 and Figure 7 As shown, the length of the groove wall on the inner side of the first guide groove section 511 extending along the length of the vehicle is less than the length of the groove wall on the inner side of the second guide groove section extending along the length of the vehicle. It is understandable that the cross-section of the second guide rail 5 is different along the height direction of the vehicle.

[0117] In the embodiment of the present invention, the door frame 100 has a shorter extension length of the first guide groove section 511 on the side closest to the interior of the vehicle in the length direction of the vehicle than the extension length of the second guide groove section 512 on the side closest to the interior of the vehicle in the length direction of the vehicle. The shorter extension length of the first guide groove section 511 provides corresponding clearance space during installation, which facilitates the installation and fixing of the second guide rail 5.

[0118] Optionally, the door frame 100 of this embodiment may further include a second sealing strip 7, which fits within the second guide groove 51. For example, the door frame 100 may also have multiple lips on the second sealing strip 7 to improve its sealing effect.

[0119] The door assembly of this invention includes a window glass assembly 200 and a door frame 100 as described above. The window glass assembly 200 is movably abutted against the guide groove along the height direction of the vehicle. It is understood that the window glass assembly 200 is movably abutted against the first sub-guide groove 21 and the second sub-guide groove 31 along the height direction of the vehicle. Therefore, the door assembly of this invention has the advantage of easy disassembly. Furthermore, it avoids the problem of a significant step difference between the upper end of the guide rail and the frame body due to excessively long guide rails, which affects the smoothness of the window glass assembly.

[0120] like Figure 8 and Figure 9 As shown, the vehicle window glass assembly 200 includes a vehicle window glass 201 and a first slider 202. One end of the first slider 202 is connected to the side of the vehicle window glass 201 near the first sub-guide groove 21, and the other end of the first slider 202 fits into the first sub-guide groove 21. It can be understood that one end of the first slider 202 is connected to the side of the vehicle window glass 201 located inside the vehicle.

[0121] In this embodiment of the invention, the door assembly has a first sub-guide groove 21 extending along the height direction of the door frame 100 on the first sub-sealing strip 41. One end of the first slider 202 is connected to the side of the window glass 201 near the first sub-guide groove 21, so that when the window glass 201 is closed or opened, the other end of the first slider 202 engages in the first sub-guide groove 21, thereby limiting the window glass 201 and fixing it. This improves the smoothness of the movement of the window glass assembly 200.

[0122] Furthermore, connecting one end of the first slider 202 to the side of the window glass 201 near the first sub-guide groove 21 helps eliminate the step difference between the window glass 201 and the door frame 100 on the outside of the vehicle compartment. For example, the outer wall of the window glass 201 can be flush with the outer wall of the first pillar trim 2. This reduces wind resistance during vehicle movement and enhances the overall aesthetics of the vehicle.

[0123] Optionally, the other end of the first slider 202 is guided and engaged with the first limiting part within the first sub-guide groove 21. In this embodiment of the invention, the door assembly can further limit the first slider 202 in the length and width directions of the vehicle through the limiting part. This further improves the reliability of the positioning of the window glass assembly 200 in the length and width directions of the vehicle.

[0124] like Figure 8 and Figure 9 As shown, the door frame 100 is the same as described above. The window glass assembly 200 also includes a second slider 203. The second slider 203 and the first slider 202 are arranged opposite to each other in the length direction of the vehicle. One end of the second slider 203 is connected to the window glass 201 on the inner side of the vehicle, and the other end of the second slider 203 is movably fitted in the second guide groove.

[0125] In this embodiment of the invention, the door assembly connects one end of the second slider 203 to the side of the window glass 201 near the first sub-guide groove 21. This helps to eliminate the step difference between the window glass 201 and the door frame 100 on the outside of the vehicle compartment. For example, the outer wall surface of the window glass 201 can be flush with the outer wall surfaces of the first pillar trim 2 and the second pillar trim 6. This not only reduces wind resistance during vehicle movement but also enhances the overall aesthetics of the vehicle.

[0126] The first sub-guide channel 21 has a first end that is relatively positioned in the height direction of the vehicle (e.g., Figure 2 The upper end shown) and the second end (e.g. Figure 2 As shown in the lower end), the upper end face of the first slider 202 is located between the first end and the second end in the height direction of the vehicle.

[0127] In this embodiment of the invention, the door assembly utilizes a sliding contact between the first end and the second end of the first slider 202 via the upper surface of the slider. In other words, when the first slider 202 moves, its travel distance is between the upper and lower ends of the first sub-guide groove 21. This prevents the first slider 202 from easily getting stuck during the switching process from the first sub-guide groove 21 to the second sub-guide groove 31. This, in turn, helps improve the smoothness of the movement of the window glass assembly 200.

[0128] like Figure 8 and Figure 9As shown, the first slider 202 is adhered to the window glass 201. The second slider 203 is adhered to the side of the window glass 201 closest to the vehicle interior. This improves the ease of installation of the first slider 202 and the second slider 203.

[0129] The vehicle of this invention includes the door assembly of any of the above embodiments. Therefore, the vehicle of this invention has the advantage of easy disassembly, and also avoids the problem of a significant step difference between the upper end of the guide rail and the frame body due to excessively long guide rails, which affects the smoothness of the window glass assembly.

[0130] The vehicle in this embodiment of the invention has a waistline located between the first sub-guide groove 21 and the second sub-guide groove 31 in the height direction of the vehicle. The first guide groove segment 511 is located above the waistline, and the second guide groove segment 512 is located below the waistline. This achieves both constraint force and smooth movement of the glass in the width direction of the vehicle, and also contributes to the aesthetic appearance of the first pillar trim panel 2 and the second pillar trim panel 6.
