Description

Technical Field

[0001] This application relates to the field of vehicles, and more particularly to a guide rail assembly and a vehicle. Background Technology

[0002] Currently, vehicle windows are equipped with guide rails along their edges. These rails guide and support the glass during window operation. However, because the shape and structure of the guide rails need to be compatible with both the vehicle body panels and the window glass, their structure is quite complex. Consequently, the production process is cumbersome, resulting in a low yield rate for guide rail production. Summary of the Invention

[0003] Embodiments of this application provide a guide rail assembly and vehicle, which can simplify the production difficulty of guide rails and thus improve the product yield of guide rails.

Detailed Implementation

[0045] For ease of understanding, the terminology used in the embodiments of this application will be explained first.

[0046] And / or: This is simply a way of describing the relationship between related objects. It indicates that there can be three kinds of relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0047] Multiple: refers to two or more.

[0048] Connection: should be interpreted broadly. For example, the connection between A and B can be a direct connection between A and B, or an indirect connection between A and B through an intermediary.

[0049] The specific embodiments of this application will now be clearly described in conjunction with the accompanying drawings.

[0050] Please see Figure 1 , Figure 1 This is a structural schematic diagram of a vehicle 1000 provided in an embodiment of this application. The vehicle 1000 includes a body sheet 100, a lifting device (not shown), a guide rail assembly 200, and a window glass 300. Both the lifting device and the guide rail assembly 200 are connected to the body sheet 100. The window glass 300 is connected to the lifting device. The window glass 300 can rise or fall under the control of the lifting device.

[0051] It should be noted that, Figure 1 The purpose of this illustration is solely to depict the connection relationship between the vehicle body sheet metal 100, the guide rail assembly 200, and the window glass 300, and is not to specifically limit the connection positions, specific structures, or quantities of each device. Furthermore, the structures illustrated in this application's embodiments do not constitute a specific limitation on the vehicle 1000. In other embodiments of this application, the vehicle 1000 may include more or fewer components than illustrated, or combine certain components, or split certain components, or have different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of both.

[0052] The vehicle body panel 100 may include a frame 110 and four doors 120. The four doors 120 are designated as a first door 121, a second door 122, a third door 123, and a fourth door 124. All four doors are connected to the frame 110. The first door 121 may be the left front door. The first door 121 has a first window 1211, which may be the driver's side window. The second door 122 may be the left rear door. The second door 122 has a second window 1221, which may be the rear left side window. The third door 123 may be the right front door. The third door 123 has a third window 1231, which may be the passenger side window. The fourth door 124 may be the right rear door. The fourth door 124 is equipped with a fourth window 1241. The fourth window 1241 is the rear right-side window. For ease of description, the following explanation uses the first door 121 as an example.

[0053] In some possible embodiments, the four windows (first window 1211, second window 1221, third window 1231, and fourth window 1241) can be frameless windows. That is, the door 120 only includes a window frame for connecting to one side of the bottom edge of the window glass 300. The door 120 does not have window frames surrounding the other three sides (side and top edges) of the window glass 300. For ease of description, the following description uses an embodiment of a frameless window.

[0054] The number of lifting devices can be four, and the four lifting devices are respectively installed on the first door 121, the second door 122, the third door 123 and the fourth door 124.

[0055] The vehicle window 300 may include a corner window 310 and a power window 320. The corner window 310 is connected to the first door 121. The corner window 310 covers the front of the first window 1211 and is positioned near the A-pillar of the vehicle frame 110. The power window 320 is mounted on a lifting device connected to the first door 121. When the power window 320 is raised, it covers the rear of the first window 1211 and is positioned near the B-pillar of the vehicle frame 110.

[0056] The guide rail assembly 200 is connected to the first door 121. The guide rail assembly 200 is located between the corner window and the lift window 320. The guide rail assembly 200 can provide guidance for the raising and lowering of the lift window 320.

[0057] Currently, guide rails are installed around the perimeter of the vehicle's window glass 300. These guide rails guide and support the glass during its raising and lowering process. However, because the shape and structure of the guide rails need to be compatible with both the vehicle body sheet metal 100 and the window glass 300, the structure is quite complex, making the production process cumbersome and resulting in a low yield rate.

[0058] Based on this, this application provides a guide rail assembly 200, which can simplify the production difficulty of the guide rail for vehicle windows, thereby improving the product yield of the guide rail.

[0059] Please refer to the following: Figure 2 and Figure 3 , Figure 2 yes Figure 1 The diagram shows a partial structural schematic of the guide rail assembly 200. Figure 3 yes Figure 1The diagram shows an enlarged view of the guide rail assembly 200. The guide rail assembly 200 may include a first guide rail 210, a second guide rail 220, a connecting bracket 230, a first seal 240, a second seal 250, a buffer (not shown), and a fixing member 270. Exemplarily, there may be three fixing members 270, namely a first connecting member 271, a second connecting member 272, and a third connecting member 273. In some possible embodiments, the materials of the first guide rail 210 and the second guide rail 220 may include AL6063 aluminum alloy. The material of the connecting bracket 230 may include DC04, ordinary cold-rolled carbon steel sheet, and steel plate cold-rolled commercial (SPCC). The material of the buffer may include ethylene propylene diene monomer (EPDM).

[0060] The first guide rail 210 provides an installation position for the second guide rail 220, the connecting bracket 230, and the first seal 240. The first connector 271, the second connector 272, and the third connector 273 can fix the first guide rail 210, the second guide rail 220, and the connecting bracket 230 together. The second seal 250 can be installed inside the second guide rail 220, and the buffer 260 can be located between the first guide rail 210 and the second guide rail 220.

[0061] It is understood that this application divides the guide rail assembly 200 into multiple sub-parts (first guide rail 210, second guide rail 220, connecting bracket 230, first seal 240, second seal 250, and buffer 260). These sub-parts can be manufactured individually during production. Each sub-part has a relatively simple structure. Therefore, the processing of a single sub-part is relatively simple, thus reducing the overall manufacturing difficulty of the guide rail assembly 200. Furthermore, manufacturing each sub-part individually can improve the yield rate of each sub-part, thereby increasing the overall yield rate of the guide rail assembly 200.

[0062] Please refer to the following: Figure 4 and Figure 5 , Figure 4 yes Figure 2 The diagram shows the structure of the first guide rail 210. Figure 5 yes Figure 4 This is an enlarged schematic diagram of the N portion of the first guide rail 210. The X direction indicates the width of the first guide rail 210. The Y direction indicates the length of the first guide rail 210. The Z direction indicates the thickness of the first guide rail 210. The first guide rail 210 is strip-shaped. The first guide rail 210 includes a first surface 211 and a second surface (…). Figure 4(Not labeled). The first surface 211 and the second surface are disposed opposite each other in the thickness direction of the first guide rail 210. The first guide rail 210 is provided with a first guide groove 212, a first hole 213, a second hole 214, a third hole 215, and a fourth hole 216. The first guide groove 212 is recessed from the first surface 211 along the thickness direction of the first guide rail 210. That is, the opening of the first guide groove 212 faces the thickness direction of the first guide rail 210. The first guide groove 212 extends along the length direction of the first guide rail 210.

[0063] Please refer to the following: Figure 5 , Figure 6 and Figure 7 , Figure 6 yes Figure 4 The diagram shows a cross-sectional view of the first guide rail 210 at point AA. Figure 7 yes Figure 4 The diagram shows a cross-sectional view of the first guide rail 210 at point BB. The first guide groove 212 includes a first groove wall 2121, a second groove wall 2122, and a third groove wall 2123. The first groove wall 2121 and the second groove wall 2122 are respectively connected to opposite sides of the third groove wall 2123. The first groove wall 2121 and the second groove wall 2122 are arranged opposite to each other in the width direction of the first guide rail 210. The end of the first groove wall 2121 away from the third groove wall 2123 is connected to the first surface 211. The first groove wall 2121 and the second groove wall 2122 are the sidewalls of the first guide groove 212. The third groove wall 2123 is the bottom wall of the first guide groove 212.

[0064] Please refer to the following: Figure 4 The first hole 213, the second hole 214, the third hole 215, and the fourth hole 216 all penetrate the first guide rail 210. Specifically, the first hole 213, the second hole 214, the third hole 215, and the fourth hole 216 penetrate the third groove wall 2123 and the second surface 217 of the first guide groove 212 along the thickness direction of the first guide rail 210. The first hole 213, the second hole 214, the third hole 215, and the fourth hole 216 are arranged alternately along the length direction of the first guide rail 210. For ease of description below, the length direction of the first guide rail 210 is defined as the first direction. The first hole 213, the second hole 214, the third hole 215, and the fourth hole 216 are arranged alternately along the first direction. The first hole 213 is a circular hole. The first hole 213 allows the first connector 271 to pass through. The second hole 214 is a circular hole. The second hole 214 allows the second connector 272 to pass through. The third hole 215 is an oblong hole. The third hole 215 allows the third connector 273 to pass through.

[0065] Please refer to the following: Figure 5 and Figure 6The first guide rail 210 also includes a first limiting portion 2101 and a second limiting portion 2102. The first limiting portion 2101 protrudes from the first groove wall 2121 and extends along the length direction of the first guide groove 212. One end of the first limiting portion 2101 is located on the groove wall (first groove wall 2121) of the first guide groove 212 between the third hole 215 and the fourth hole 216. The first limiting portion 2101 extends along a first direction. The length of the first limiting portion 2101 is less than the length of the first guide rail 210.

[0066] The second limiting part 2102 protrudes from the second groove wall 2122 and extends along the length direction of the first guide groove 212. The length of the second limiting part 2102 can be equal to the length of the first guide rail 210.

[0067] Please see Figure 8 , Figure 8 for Figure 2 The diagram shows a structural schematic of the second guide rail 220 at an angle. The second guide rail 220 includes a first part 221, a second part 222, and a third part 223. The first part 221 and the second part 222 are connected to opposite sides of the third part 223. The first part 221 and the second part 222 are arranged opposite each other in the Z direction. The first part 221, the second part 222, and the third part 223 together form a second guide groove 2201. The first part 221 and the second part 222 are the sidewalls of the second guide groove 2201, and the third part 223 is the bottom wall of the second guide groove 2201. The opening of the second guide groove 2201 faces the X direction.

[0068] Understandably, the opening of the first guide groove 212 of the first guide rail 210 and the opening of the second guide groove 2201 of the second guide rail 220 face different directions, so that the groove wall of the first guide groove 212 and the groove wall of the second guide groove 2201 can limit the first seal 240, the second seal 250 and the lifting glass 320 from different directions, thereby increasing the stability of the first seal 240, the second seal 250 and the lifting glass 320.

[0069] Please refer to the following: Figure 9 and Figure 10 , Figure 9 yes Figure 8 The diagram shows a cross-sectional view of the second guide rail at point CC. Figure 10 yes Figure 8The diagram shows a second guide rail 220 from another angle. The first portion 221 has a first protrusion 2211 and a second protrusion 2212. The first protrusion 2211 protrudes from the surface of the first portion 221 facing away from the second portion 222. There are two first protrusions 2211. The second protrusion 2212 protrudes from the surface of the first portion 221 facing the second portion 222. The first portion 221 also has a first connecting hole 2213 and a second connecting hole 2214. The first connecting hole 2213 penetrates the first portion 221 and one first protrusion 2211 in the thickness direction of the first portion 221. The second connecting hole 2214 penetrates the first portion 221 and another first protrusion 2211 in the thickness direction of the first portion 221. The first connecting hole 2213 and the second connecting hole 2214 are arranged sequentially along the length direction of the second guide rail 220. Both the first connecting hole 2213 and the second connecting hole 2214 are circular holes. The first connecting hole 2213 is used for the first connector 271 to pass through. The second connecting hole 2214 is used for the second connector 272 to pass through.

[0070] For some possible implementations, please refer to [link / reference]. Figure 8 The first part 221 may also be provided with a first countersunk hole 2215 and a second countersunk hole 2216. Both the first countersunk hole 2215 and the second countersunk hole 2216 are recessed from the surface of the first part 221 facing the second part 222. The first countersunk hole 2215 communicates with the first connecting hole 2213. The second countersunk hole 2216 may communicate with the second connecting hole 2214. The distance between the bottom wall of the first countersunk hole 2215 and the surface of the first part 221 facing away from the second part 222 can be greater than or equal to 2 mm. When the bolt (the second connector 272 or the third connector 273 described below) is connected to the wall of the first countersunk hole 2215, the top of the bolt is recessed relative to the surface of the first part 221 facing the second part 222. The distance between the bolt and the surface of the first part 221 facing the second part 222 can be less than or equal to 0.1 mm.

[0071] Understandably, the first countersunk hole 2215 can be used to accommodate the end of a bolt passing through the first connecting hole 2213, and the second countersunk hole 2216 can be used to accommodate the end of a bolt passing through the second connecting hole 2214. The first countersunk hole 2215 and the second countersunk hole 2216 prevent the end of the bolt from protruding relative to the surface of the first part 221 facing the second part 222 and thus occupying the installation position of the second seal 250. This avoids affecting the raising and lowering process of the window glass 300.

[0072] Please continue reading. Figure 8The second part 222 is provided with two clearance holes 2221. The two clearance holes 2221 extend through the second part 222 along its thickness direction. For example, the clearance holes 2221 may also extend through the side of the second part 222 away from the third part 223. The orthographic projections of the two clearance holes 2221 onto the first part 221 respectively cover the first connecting hole 2213 and the second connecting hole 2214.

[0073] Please refer to the following: Figure 9 The second part 222 is also provided with a third protrusion 2222, which protrudes from the surface of the second part 222 facing the first part 221. The third protrusion 2222 can be disposed opposite to the second protrusion 2212.

[0074] Understandably, the clearance hole 2221 provides operating space for the bolt when it is inserted into the first connecting hole 2213 and the second connecting hole 2214. This facilitates the worker inserting the bolt into the first connecting hole 2213 and the second connecting hole 2214 from one side of the second guide rail 220.

[0075] Please refer to the following: Figure 2 and Figure 11 . Figure 11 yes Figure 2 The diagram shows a cross-sectional view of the first guide rail 210 and the second guide rail 220 at point DD. The second guide rail 220 is connected to the bottom wall of the first guide groove 212. In a first direction, the second guide rail 220 is offset from the first limiting portion 2101 of the first guide rail 210. At least a portion of the second guide rail 220 is located within the first guide groove 212. A first gap a is formed between the second guide rail 220 and the first groove wall 2121 of the first guide rail 210. A second gap b is formed between the second guide rail 220 and the second limiting portion 2102 of the first guide rail 210. The second guide groove 2201 of the second guide rail 220 communicates with the first guide groove 212 and is used to cooperate with the first guide groove 212 to accommodate the vehicle window glass 300.

[0076] Specifically, the first portion 221 of the second guide rail 220 is connected to the bottom wall of the first guide groove 212. The first protrusion 2211 contacts the third groove wall 2123 of the first guide groove 212. A third gap exists between the first portion 221 and the third groove wall 2123 of the first guide groove 212. The size of the third gap can be between 0.4mm and 0.6mm. Specifically, the size of the third gap can be 0.5mm. The first connecting hole 2213 of the first portion 221 is opposite to the second hole 214 of the first guide rail 210. The second connecting hole 2214 of the first portion 221 is opposite to the third hole 215 of the first guide rail 210. A second gap b exists between the first portion 221 and the second limiting portion 2102. The second gap b is greater than or equal to 2mm. The third portion 223 is located on the side of the first portion 221 and the second portion 222 facing the third groove wall 2123. Part of the third portion 223 is located within the first guide groove 212. The third portion 223 is located outside the first guide rail 210. The third portion 223 is offset from the first limiting portion 2101 of the first guide rail 210. There is a first gap a between the third portion 223 and the first groove wall 2121. The first gap a is greater than or equal to 2mm. The second portion 222 is located outside the first guide rail 210.

[0077] It is understood that, in the width direction of the guide rail assembly 200, there is a first gap a and a second gap b between the first guide rail 210 and the second guide rail 220. In the thickness direction of the guide rail assembly 200, there is a third gap between the first guide rail 210 and the second guide rail 220. This prevents poor matching of the two guide rails due to tolerance fluctuations, and avoids the second guide rail 220 failing to be fixedly connected to the first guide rail 210. It ensures a stable connection between the first guide rail 210 and the second guide rail 220.

[0078] Please refer to the following: Figure 12 , Figure 12 yes Figure 2The diagram shows the structure of the connecting bracket 230. The connecting bracket 230 includes a first connecting portion 231, a second connecting portion 232, and a middle portion 233. Along the length of the connecting bracket 230, the first connecting portion 231, the middle portion 233, and the second connecting portion 232 are connected sequentially. Both the first connecting portion 231 and the second connecting portion 232 are bent and connected to opposite ends of the middle portion 233. The first connecting portion 231 has a third connecting hole 2311 and a fourth connecting hole 2312. The third connecting hole 2311 and the fourth connecting hole 2312 penetrate the first connecting portion 231 along its thickness direction. The third connecting hole 2311 and the fourth connecting hole 2312 are sequentially arranged along the width direction of the connecting bracket 230. The second connecting portion 232 has a fifth connecting hole 2331. The fifth connecting hole 2331 penetrates the second connecting portion 232 along its thickness direction.

[0079] The first connecting part 231 of the connecting bracket 230 is connected to the side of the first guide rail 210 opposite to the second guide rail 220. The third connecting hole 2311 is corresponding to the first hole 213. The fourth connecting hole 2312 is corresponding to the second hole 214. The second connecting part 232 of the connecting bracket 230 is connected to the door 120 of the body sheet metal 100.

[0080] Please see Figure 13 , Figure 13 yes Figure 2 The diagram shows a cross-sectional view at EE of the first guide rail 210, the second guide rail 220, and the connecting bracket 230. A first connector 271 passes sequentially through a first hole 213 in the first guide rail 210 and a third connecting hole 2311 in the connecting bracket 230, thereby fixing the first guide rail 210 and the connecting bracket 230 together. Exemplarily, the first connector 271 may include a bolt 2711 and a nut 2712. The bolt 2711 may pass sequentially through the first guide rail 210 and the connecting bracket 230. The nut 2712 may be located on the side of the connecting bracket 230 opposite to the first guide rail 210. The nut 2712 may be fastened to the bolt 2711. In some possible embodiments, the nut 2712 may also be directly welded to the side of the connecting bracket 230 opposite to the first guide rail 210.

[0081] Please see Figure 14 , Figure 14 yes Figure 2The diagram shows a cross-sectional view of the first guide rail 210, the second guide rail 220, and the connecting bracket 230 at point FF. The second connector 272 passes sequentially through the first connecting hole 2213 of the second guide rail 220, the second hole 214 of the first guide rail 210, and the fourth connecting hole 2312 of the connecting bracket 230. This securely connects the second guide rail 220, the first guide rail 210, and the connecting bracket. The structure of the second connector 272 can be found in the description of the structure of the first connector 271 above. This application will not elaborate on the structure of the second connector 272.

[0082] The third connector 273 passes sequentially through the second connecting hole 2214 of the second guide rail 220 and the third hole 215 of the first guide rail 210, thereby fixing the second guide rail 220 and the first guide rail 210 together. The structure of the third connector 273 can be found in the description of the structure of the first connector 271 above. This application will not elaborate on the structure of the third connector 273.

[0083] Please refer to the following: Figure 13 The buffer element 260 can be made of foam. The buffer element 260 can be filled within the third gap. It is understood that the buffer element 260 can act as a buffer between the first guide rail 210 and the second guide rail 220, preventing the first guide rail 210 and the second guide rail 220 from colliding and causing abnormal noise.

[0084] Please see Figure 15 , Figure 15 yes Figure 3 The diagram shows a cross-sectional view of the guide rail assembly 200 at point GG. The first seal 240 can be strip-shaped. The first seal 240 includes a first body 241, a first side portion 242, a first sealing lip 243, a second sealing lip 244, a limiting post 245, and a first engaging portion 246. The first side portion 242 and the first body 241 are bent and connected. The first sealing lip 243 is bent and connected to the side of the first body 241 away from the first side portion 242. The first sealing lip 243 is disposed opposite to the first side portion 242. The first sealing lip 243 can be inclined from the first body 241 toward the first side portion 242. A second limiting groove 247 is recessed on the surface of the body away from the first sealing lip 243. The second limiting groove 247 can be provided at the end of the first body 241 away from the first side portion 242.

[0085] The second sealing lip 244 is connected to the side of the first side portion 242 away from the first body 241. The second sealing lip 244 is bent and connected to the first side portion 242. The second sealing lip 244 can be inclined from the second side portion toward the first body 241. The limiting post 245 protrudes from the first body 241 away from the first side portion 242 and the first sealing lip 243. The first engaging portion 246 is connected to the side of the first side portion 242 away from the first sealing lip 243. The first engaging portion 246 can be L-shaped. The first engaging portion 246 can extend from the first side portion 242 away from the first side portion 242, and then extend along the first body 241 toward the second sealing lip 244. A first limiting groove 248 is formed between the first engaging portion 246 and the first side portion 242. The first limiting groove 248 and the second limiting groove 247 are also located on opposite sides of the first seal 240 along the width direction.

[0086] Please refer to the following: Figure 3 , Figure 15 and Figure 16 , Figure 16 yes Figure 3 The diagram shows a cross-sectional view at point II of the guide rail assembly 200. A first seal 240 is connected to a first guide groove 212, with at least a portion of the first seal 240 located within the first guide groove 212. The first seal 240 is spaced apart from or in contact with the second guide rail 220. When the first seal 240 and the second guide rail 220 are spaced apart, the distance d between them can be greater than or equal to 5 mm. The first seal 240 is used for sealing the connection between the first guide rail 210 and the window glass 300.

[0087] It is understandable that the distance d between the first seal 240 and the second guide rail 220 can be used as an assembly redundancy position for the first seal 240 during installation. Even with a slightly larger length, the first seal 240 can still be installed within the first guide rail 210 without interfering with the second guide rail 220.

[0088] Specifically, the limiting post 245 of the first seal 240 can be connected to the wall of the fourth hole 216 of the first guide rail 210. At least a portion of the limiting post 245 is located within the fourth hole 216 of the first guide rail 210. At least a portion of the first body 241 can be located within the first guide groove 212. The first engaging portion 246 abuts against the surface of the first limiting portion 2101 facing the third groove wall 2123. The first limiting portion 2101 can be located within the first limiting groove 248. At least a portion of the first side portion 242 can be located outside the first guide groove 212. The second limiting portion 2102 is located within the second limiting groove 247. This allows the first sealing strip to be mutually limited with the first guide rail 210. The first sealing lip 243 and the second sealing lip 244 are located outside the first guide groove 212.

[0089] Understandably, the limiting post 245 can fix the first seal 240 to the first guide rail 210, preventing the first sealing strip from sliding within the first guide groove 212.

[0090] For some possible implementations, please refer to Figure 3 At the end of the first seal 240, the end of the first sealing lip 243 and the end of the second sealing lip 244 can be connected to the surface of the first body 241. This strengthens the structure of the first seal 240 and prevents it from detaching from the first body 241 due to the low structural strength of the ends of the first sealing lip 243 and the second sealing lip 244.

[0091] Please see Figure 17 , Figure 17 yes Figure 3 The diagram shows a cross-sectional view of the guide rail assembly 200 at point HH. The second seal 250 can be strip-shaped. The second seal 250 includes a second body 251, a second side portion 252, a third side portion 253, a third sealing lip 254, a fourth sealing lip 255, a second engaging portion 256, a third engaging portion 257, and a fourth retaining portion 258. The second side portion 252 and the third side portion 253 are respectively connected to opposite sides of the second body 251 along the width direction. The second side portion 252 is bent and connected to the second body 251. The third side portion 253 is bent and connected to the second body 251. The second side portion 252 and the third side portion 253 are disposed opposite each other.

[0092] The third sealing lip 254 is connected to the side of the second side 252 away from the second body 251. The third sealing lip 254 is bent and connected to the second side 252. The third sealing lip 254 is inclined from the second side 252 toward the second body 251. The fourth sealing lip 255 is connected to the side of the third side 253 away from the second body 251. The fourth sealing lip 255 is bent and connected to the third side 253. The fourth sealing lip 255 is inclined from the third side 253 toward the second body 251. The side of the fourth sealing lip 255 away from the third side 253 can contact the side of the third sealing lip 254 away from the second side 252.

[0093] The second latching portion 256 and the third latching portion 257 are respectively connected to opposite sides of the second body 251 along the width direction, and are located on the side surface of the second body 251 opposite to the second side portion 252 and the third side portion 253.

[0094] The fourth retaining part 258 protrudes from the surface of the second side part 252 away from the third sealing lip 254. The fourth retaining part 258 is located on the side of the second side part 252 away from the second column.

[0095] The second seal 250 is connected to the second guide groove 2201, and at least a portion of the second seal 250 is located within the second guide groove 2201. The second seal 250 is used to seal the connection between the second guide rail 220 and the window glass 300.

[0096] Specifically, the second body 251 of the second seal 250 is disposed opposite to the third portion 223 of the second guide rail 220. The second engaging portion 256 abuts against the second protrusion 2212 of the first portion 221. The third engaging portion 257 abuts against the third protrusion 2222 of the second portion 222. The second side portion 252 is disposed opposite to the first portion 221. The fourth holding portion 258 abuts against the edge of the first portion 221 opposite to the third portion 223. The third side portion 253 is disposed opposite to the second portion 222.

[0097] It is understandable that the first seal 240 and the second seal 250 can be made of elastic materials. The first seal 240 and the second seal 250 can buffer and guide the window glass 300 during its raising or lowering.

[0098] In some possible implementations, the second seal 250 may be integrally formed with the first seal 240. The second side 252 of the second seal 250 may be connected to the first body 241 of the first seal 240. Furthermore, the third sealing lip 254 of the second seal 250 may be connected to the first sealing lip 243 of the first seal 240. The third sealing lip 254 of the second seal 250 and the first sealing lip 243 of the first seal 240 are flush in the Z-direction.

[0099] The integral molding of the first seal 240 and the second seal 250 enhances the structural strength of their connection. It prevents gaps at the connection point, which could affect the sealing performance of the first and second seals 240. When the first sealing lip 243 and the third sealing lip 254 are flush, they jointly guide the glass 320. When the glass 320 passes through the connection point of the first and third sealing lips 243 and 254, it can pass smoothly without significant resistance. Furthermore, the first and third sealing lips 243 and 254 remain in contact with the glass 320 throughout its movement, ensuring that the first and second seals provide effective guidance and cushioning.

[0100] The fourth sealing lip 255 of the second seal 250, facing the first seal 240, can be tilted upwards in the opposite direction of the Z-direction; that is, the fourth sealing lip 255 of the second seal 250 can be tilted upwards a certain distance away from the first guide rail 210. When the window glass slides from the second sealing lip 244 to the fourth sealing lip 255, the lift-up glass 320 can slide along the side of the fourth sealing lip 255 facing the first guide rail 210. The tilted portion of the fourth sealing lip 255 can guide the lift-up glass 320.

[0101] The edge of the lift-up glass 320 facing the corner window glass 310 can be located within the first seal 240 and the second seal 250. The first sealing lip 243 and the second sealing lip 244 of the first seal 240 can be located on opposite sides of the lift-up glass 320 along the thickness direction. The third sealing lip 254 and the fourth sealing lip 255 of the second seal 250 can be located on opposite sides of the lift-up glass 320 along the thickness direction. This seals the side edges of the lift-up glass 320.

[0102] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
