Description

Technical Field

[0001] This application relates to the field of glass accessory installation, and more particularly to a glass assembly and vehicle. Background Technology

[0002] Vehicle fixed windows typically have guide rails along their edges to support and guide the movement of the window regulators. These rails are usually attached to the fixed window edge using adhesive or similar methods. However, in rainy weather or during car washes, the impact of external water flow is significant, allowing water to easily seep into the vehicle through the gap between the fixed window glass and the guide rails. Water ingress can affect the vehicle's electrical system or damage the interior trim. Optimizing the seal between the fixed window glass and the guide rails is a pressing issue that needs to be addressed. Summary of the Invention

[0003] Embodiments of this application provide a glass assembly and vehicle that can reduce the possibility of water entering the vehicle interior through the connection gap between the fixed window glass and the guide rail by designing the structure of the injection molded body.

[0004] In a first aspect, this application provides a glass assembly, comprising:

[0005] A fixed window glass includes an inner surface and a first side surface, the inner surface being oriented toward the interior of the vehicle, and the first side surface being connected to an edge of the inner surface;

[0006] The guide rail includes a mounting portion and a guide portion connected to each other. The mounting portion is connected to the inner surface and extends along a first direction, which is the extension direction of the first side. The guide portion is connected to the side of the mounting portion opposite to the fixed window glass.

[0007] An injection molded body includes a fixing part connected to the inner surface, the fixing part being located on the side of the mounting part facing the first side, and the fixing part extending along the first direction.

[0008] In this embodiment, the fixing part can be located between the first side of the fixed window glass and the mounting part of the guide rail. The fixing part of the injection molded body is formed during the integral injection molding process of the injection molded body and the fixed window glass. The integral injection molding connection avoids problems such as loose joints or misalignments that may occur during subsequent assembly, thereby making the connection between the fixing part and the fixed window glass tighter. Moreover, during the integral injection molding process, the injection molded body is directly formed on the periphery of the fixed window glass. The connection surface between the injection molded body and the fixed window glass is subjected to balanced force, reducing areas of stress concentration, thereby making the connection between the injection molded body and the fixed window glass more stable. Because the connection strength between the injection molded body and the fixed window glass is high and the connection position is relatively tight, there are basically no gaps between the injection molded body and the fixed window glass.

[0009] Since the window rails are typically bonded to the fixed window glass using adhesive, the quality of the adhesive affects the connection strength between the rails and the fixed window glass. Over time, the adhesive may age, harden, and crack due to UV exposure, temperature changes, etc., thus losing its sealing function. If the rails and fixed window glass are not properly positioned or subjected to uneven pressure during installation, gaps may exist between the adhesive and the fixed window glass or rails, leading to seal failure. Under continuous wind pressure or water flow, water may gradually seep through the adhesive and enter the vehicle interior.

[0010] This embodiment of the application, by placing the fixing part of the injection-molded body on the side of the mounting part facing the edge of the fixed window glass, can prevent water flow from passing through the edge of the fixed window glass and being blocked on the first side of the fixing part facing the fixed window glass. This prevents water flow from passing through the gap between the fixing part and the fixed window glass, thereby preventing water from entering the vehicle interior through the gap between the mounting part of the guide rail and the fixed window glass. This protects the vehicle's electrical system and interior trim from water flow.

[0011] In one possible implementation, the injection-molded body further includes a blocking portion connected to the side of the fixing portion away from the fixed window glass and connected to the end of the fixing portion facing the roof. At least a portion of the blocking portion is embedded in the end of the guide portion facing the roof, and the blocking portion protrudes relative to the first side.

[0012] In one possible implementation, the blocking part is connected to the end of the fixing part facing the roof, and the orthogonal projection of the blocking part onto the fixed window glass covers the side of the first side facing the roof.

[0013] In one possible implementation, the injection-molded body further includes a first connecting portion, and the fixed window glass further includes a second side surface, the second side surface being directed toward the top of the vehicle, the second side surface being bent and connected to the first side surface, the second side surface being connected to the edge of the inner surface, and the second side surface being spaced apart from the end of the mounting portion directed toward the top of the vehicle.

[0014] The first connecting portion covers the second side surface and part of the inner surface, and part of the first connecting portion is located between the end of the mounting portion and the second side surface. The first connecting portion is connected to the fixing portion at one end facing the roof.

[0015] In one possible implementation, the first connecting portion is provided with a clearance notch that penetrates two surfaces of the first connecting portion in the thickness direction, the guide portion is spaced apart from the inner surface, at least a portion of the blocking portion is located between the guide portion and the inner surface, and the end of the mounting portion facing the roof is located within the clearance notch.

[0016] In one possible implementation, the injection-molded body further includes an abutment block, one end of which is connected to the inner wall of the clearance notch, and the other end of which abuts against the mounting portion.

[0017] In one possible implementation, the glass assembly further includes a seal, the blocking portion includes a first segment and a second segment, the first segment is connected to the surface of the fixing portion away from the fixed window glass, the first segment extends in a direction away from the fixed window glass, the second segment is bent and connected to the side of the first segment away from the fixing portion, the second segment protrudes relative to the first side, the fixing portion, the first segment and the second segment form a drainage groove, and a portion of the seal is located in the drainage groove.

[0018] In this embodiment, after the water flows past the first side, it reaches the blocking part and is blocked by the channel wall of the blocking part's drainage groove. The water can then flow downwards along the drainage groove, thereby preventing water from entering the vehicle interior.

[0019] Alternatively, under water pressure, the water flow can pass through the first side of the fixed window glass to the wall of the drainage channel, then bypass the first and second sections of the obstruction section, flowing from the second section towards the surface of the guide rail, and then towards the guide section of the guide rail at the end facing the roof. In this case, the water flow has a longer path. Therefore, when the water reaches the guide section of the guide rail, the water flow has less force, which is insufficient to support the water continuing to flow upwards along the surface of the guide section. At this point, the water may flow downwards along the surface of the guide section under the influence of gravity, and then flow out through the door towards the outside of the vehicle. Ultimately, this achieves the effect of preventing water from entering the vehicle from the edge of the fixed window glass, improving the sealing performance of the glass assembly.

[0020] In one possible implementation, the seal includes a sealing body and a protrusion, a portion of the sealing body being located within the drainage groove, the protrusion being connected to the surface of the sealing body facing the groove wall of the drainage groove, and the protrusion abutting against the groove wall of the drainage groove.

[0021] In this embodiment, the protrusion can seal the gap between the sealing body and the guide rail, and the gap between the sealing body and the injection molded body, so as to minimize the flow of water between the sealing body and the guide rail, and between the sealing body and the injection molded body.

[0022] In one possible implementation, the injection-molded body further includes an extension connected to the side of the blocking portion away from the seal and extending away from the fixed window glass, the extension being used to fit against the body sheet metal.

[0023] In one possible implementation, the injection-molded body further includes a snap-fit ​​portion connected to the fixing portion and extending toward a side opposite to the mounting portion, the snap-fit ​​portion being protruding relative to the first side surface.

[0024] Secondly, this application provides a vehicle, including a vehicle body and a glass assembly as described above, the glass assembly being mounted on the vehicle body. Attached Figure Description

Detailed Implementation

[0038] For ease of understanding, the terminology used in the embodiments of this application will be explained first.

[0039] 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.

[0040] Multiple: refers to two or more.

[0041] 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.

[0042] The specific embodiments of this application will now be clearly described in conjunction with the accompanying drawings.

[0043] Please see Figure 1 , Figure 1 This is a structural schematic diagram of a vehicle 100 provided in an embodiment of this application. The vehicle 100 includes a body 10, a power window 20, and a glass assembly 30. The power window 20 and the glass assembly 30 can both be connected to the doors of the body 10. For example, the glass assembly 30 can be located in the common position of the front quarter window of the vehicle 100. The power window 20 can be the side windows on the front of the vehicle 100. In some other embodiments, the power window 20 and the glass assembly 30 can also be located in other positions on the vehicle 100; this application does not limit the installation position of the power window 20 and the glass assembly 30.

[0044] in, Figure 1 In the diagram, the X direction represents the length of vehicle 100. The Y direction represents the width of vehicle 100. The Z direction represents the height of vehicle 100.

[0045] It should be noted that, Figure 1 The purpose is merely to illustratively describe the connection relationship between the vehicle body 10, the lift window 20, and the glass assembly 30, and is not to specifically limit the connection position, specific structure, or quantity of each device. Furthermore, the structure illustrated in the embodiments of this application does not constitute a specific limitation on the vehicle 100. In other embodiments of this application, the vehicle 100 includes... Figure 1 This may involve more or fewer components, or combining certain components, or splitting certain components, or different component arrangements.

[0046] The vehicle body 10 includes a body sheet 11, two front doors 12, and two rear doors 13. The two front doors 12 are respectively connected to both sides of the body sheet 11 in the width direction. The two rear doors 13 are respectively connected to both sides of the body sheet 11 in the width direction and are located on the side of the front doors 12 facing the rear of the vehicle.

[0047] A glass assembly 30 and a lift-up glass 20 can constitute a set of vehicle window glass. Vehicle 100 may include multiple sets of vehicle window glass. A set of vehicle window glass is connected to a door (front door 12 or rear door 13).

[0048] The power window 20 can rise or fall in the height direction of the vehicle (100 meters) to open or close the window on the door. For example, the power window 20 can be transparent low-iron glass (also known as ultra-clear glass), soda-lime glass, borosilicate glass, aluminosilicate glass, or K-glass, etc. The power window 20 can also be tempered glass. Tempering the power window 20 increases its rigidity and reduces deformation. In practical use, its higher rigidity makes it less susceptible to damage from external forces, allowing it to adapt to a wider range of usage scenarios.

[0049] Vehicle fixed windows typically have guide rails along their edges to support and guide the movement of the window regulators. In actual manufacturing, some vehicles cannot have their guide rails integrally molded with the fixed window. In such cases, the guide rails are usually attached to the window edge using adhesives. Because adhesive bonding has limited strength, a complete seal between the guide rail and the fixed window glass is difficult after assembly. In rainy weather or during car washes, the impact of external water flow is significant, allowing water to easily enter the vehicle through the gap between the fixed window glass and the guide rail. Water ingress can affect the vehicle's electrical system or damage the interior trim. Optimizing the seal between the fixed window glass and the guide rail is a pressing issue that needs to be addressed.

[0050] Based on this, please refer to Figure 2 , Figure 2 yes Figure 1 The diagram shows a partial structural schematic of the glass assembly 30. This application provides an embodiment of the glass assembly 30 to exemplarily describe its structure. The glass assembly 30, through its injection-molded structure design, can reduce the possibility of water entering the vehicle interior from the connection gap between the fixed window glass and the guide rail.

[0051] in, Figure 2 As shown, the X direction is the width direction of the glass assembly 30, which is set along the length direction of the vehicle 100; the Y direction is the thickness direction of the glass assembly 30, which is set along the width direction of the vehicle 100; and the Z direction is the height direction of the glass assembly 30, which is set along the height direction of the vehicle 100.

[0052] The glass assembly 30 includes a fixed window glass 31, a guide rail 32, an injection-molded body 33, and a seal 34. The guide rail 32 is connected to the side of the fixed window glass 31 facing the lift-up glass 20 of the vehicle 100, and the injection-molded body 33 is arranged around the periphery of the fixed window glass 31. The seal 34 can be installed within the installation space formed by the injection-molded body 33 and the guide rail 32.

[0053] Please refer to Figure 3 , Figure 3 yes Figure 2 The diagram shows the structure of the fixed window glass 31. The fixed window glass 31 includes an inner surface 311, an outer surface 312, and a peripheral surface 313. The inner surface 311 and the outer surface 312 are arranged opposite to each other along the thickness direction of the fixed window glass 31. The peripheral surface 313 is connected to the periphery of the inner surface 311 and the outer surface 312. The peripheral surface 313 includes a first side surface 3131, a second side surface 3132, and a third side surface 3133. The first side surface 3131, the second side surface 3132, and the third side surface 3133 are bent and connected in sequence. The first side surface 3131 is the surface of the fixed window glass 31 facing the lift glass 20. The extension direction of the first side surface 3131 is a first direction, which is also the Z direction shown in the figure. The second side surface 3132 is the surface of the fixed window glass 31 facing the roof.

[0054] The third side 3133 is the surface of the fixed window glass 31 facing the bottom of the vehicle.

[0055] The fixed window glass 31 can be the triangular window glass at the front door 12 of the vehicle 100. Alternatively, the fixed window glass 31 can be the triangular window glass at the rear door 13 of the vehicle 100. Furthermore, the fixed window glass 31 can also be other glass adapted to the shape of the vehicle 100. This application does not limit the shape of the fixed window glass 31; the fixed window glass 31 is simply glass that is fixedly installed on the side of the vehicle 100.

[0056] The fixed window glass 31 can be tempered glass. Tempered glass can be transparent low-iron glass (also known as ultra-clear glass), soda-lime glass, borosilicate glass, aluminosilicate glass, or K-glass, etc. The fixed window glass 31 can also be tempered glass. Tempering the fixed window glass 31 increases its rigidity and reduces deformation. In practical use, its higher rigidity makes it less susceptible to damage from external forces, allowing it to adapt to more usage scenarios. The fixed window glass 31 can also be semi-tempered glass. This type of glass combines the high strength of tempered glass with the disadvantage of fully tempered glass, which is prone to shattering upon breakage. When semi-tempered fixed window glass 31 is broken, it can radially crack along the crack source, generally without tangential crack propagation, thus maintaining its integrity and preventing collapse after breakage.

[0057] Fixed window glass 31 can also be laminated glass. Laminated glass is a composite glass product made by sandwiching one or more layers of organic polymer interlayer between two or more panes of glass. After special high-temperature pre-pressing (or vacuuming) and high-temperature, high-pressure processes, the glass and interlayer are permanently bonded together. Laminated glass has excellent safety performance. It also provides sound insulation and controls sunlight and ultraviolet rays.

[0058] The fixed window glass 31 can also be any type of commonly used vehicle window glass. This application does not limit the specific structure of the fixed window glass 31. The above description of the fixed window glass 31 is merely illustrative.

[0059] Please refer to the following: Figure 2 and Figure 4 , Figure 4 yes Figure 2 The diagram shows the structure of the guide rail 32. The guide rail 32 includes a mounting part 321 and a guide part 322. The mounting part 321 is used for fixed connection with the fixed window glass 31. The guide part 322 is used to provide a guiding structure for the seal 34.

[0060] The mounting portion 321 is provided with a connecting groove 3211, a snap-fit ​​groove 3212, a first clearance groove 3213, and a second clearance groove 3215. The connecting groove 3211 is recessed in one surface of the mounting portion 321 in the thickness direction. The connecting groove 3211 provides an adhesive bonding position for the adhesive. The snap-fit ​​groove 3212 is recessed in one side of the mounting portion 321 in the width direction. A first limiting body 3214 protrudes from the groove wall of the snap-fit ​​groove 3212 away from the guide portion 322. The snap-fit ​​groove 3212 provides an installation position for the seal 34. The first clearance groove 3213 is recessed in one side of the mounting portion 321 in the width direction and penetrates the bottom surface of the connecting groove 3211, the side wall of the snap-fit ​​groove 3212, and the surface of the mounting portion 321 facing the roof. The length of the first clearance groove 3213 can be less than the length of the mounting portion 321. The first clearance groove 3213 is used to avoid the fixing part of the injection molded body 33.

[0061] The second clearance groove 3215 is recessed from the bottom wall of the first clearance groove 3213. The second clearance groove 3215 is located at the end of the mounting portion 321 facing the roof. The second clearance groove 3215 penetrates the bottom surface of the connecting groove 3211, the side wall of the engaging groove 3212, and the surface of the mounting portion 321 facing the roof. The length of the second clearance groove 3215 is less than the length of the first clearance groove 3213, so that one side surface of the mounting portion 321 in the width direction is stepped. The second clearance groove 3215 can be used to avoid obstructions from the injection-molded body 33.

[0062] Mounting part 321 is connected to the inner surface 311 of fixed window glass 31, and extends along a first direction (Z direction). Mounting part 321 is spaced from the edge of inner surface 311. That is, mounting part 321 is spaced from first side surface 3131, second side surface 3132, and third side surface 3133. First clearance groove 3213 is located at the Z-direction-facing end of mounting part 321 and penetrates the surface of mounting part 321 facing first side surface 3131. The opening of the snap-fit ​​groove 3212 of mounting part 321 faces the X-direction. Connecting groove 3211 of mounting part 321 faces inner surface 311. The bottom of connecting groove 3211 can be bonded to inner surface 311 with an adhesive. The adhesive is located on the side of first clearance groove 3213 opposite to first side surface 3131. For example, the adhesive can be polyurethane adhesive.

[0063] There is a gap between the guide portion 322 and the inner surface 311 of the fixed window glass 31. The guide portion 322 is connected to the side of the mounting portion 321 opposite to the fixed window glass 31. That is, the guide portion 322 is connected to the side of the mounting portion 321 facing the X direction. The guide portion 322 and the mounting portion 321 are bent together. The guide portion 322 extends in the X direction. The guide portion 322 protrudes from the first side surface 3131 of the fixed window glass 31.

[0064] Please refer to the following: Figure 5 and Figure 6 , Figure 5 yes Figure 2 A partial structural schematic diagram of the injection molded body 33 shown. Figure 6 yes Figure 2 The diagram shows a cross-sectional view of the glass assembly 30 at point AA. The injection-molded body 33 can be an edging structure for the glass assembly 30. The injection-molded body 33 includes a first connecting part 331, a fixing part 332, a blocking part 333, an extension part 334, and a snap-fit ​​part 335. The first connecting part 331, the fixing part 332, the blocking part 333, the extension part 334, and the snap-fit ​​part 335 can be wrapped around the outer periphery of the fixed window glass 31 by injection molding.

[0065] The first connecting portion 331 can cover the remaining areas of the peripheral side surface 313 of the fixed window glass 31, excluding the first side surface 3131. That is, the first connecting portion 331 can cover the second side surface 3132 and the third side surface 3133 of the fixed window glass 31. Specifically, the first connecting portion 331 can cover the second side surface 3132, the third side surface 3133, and part of the edge area of ​​the inner surface 311.

[0066] The first connecting portion 331 is provided with a clearance notch 3311. The clearance notch 3311 is located in the part of the first connecting portion 331 that connects to the second side surface 3132, and penetrates both surfaces of the first connecting portion 331 in the thickness direction and one side surface of the first connecting portion 331 facing the opposite direction of the Z direction. The clearance notch 3311 can provide a mounting position for one end of the mounting portion 321 of the guide rail 32. The Z-direction-facing end of the mounting portion 321 is located within the clearance notch 3311. That is, the end of the mounting portion 321 facing the roof is spaced apart from the second side surface 3132, and a portion of the first connecting portion 331 is connected to the inner surface 311 of this spaced portion.

[0067] In some possible embodiments, the injection-molded body 33 may also be provided with an abutment block 3312. One end of the abutment block 3312 is connected to the inner wall of the clearance notch 3311 of the first connecting portion 331. The other end of the abutment block 3312 abuts against the mounting portion 321. In this embodiment, the abutment block 3312 can seal the gap between the mounting portion 321 and the first connecting portion 331, preventing water from entering the interior of the vehicle 100 through the gap between the mounting portion 321 and the first connecting portion 331.

[0068] The fixing portion 332 of the injection-molded body 33 is connected to the inner surface 311. The fixing portion 332 is located on the side of the mounting portion 321 facing the first side surface 3131, and extends along the first direction (Z direction). The end of the fixing portion 332 facing the roof is connected to the end of the first connecting portion 331 facing the first side surface 3131. Part of the fixing portion 332 is located in the first clearance groove 3213 of the mounting portion 321 of the guide rail 32.

[0069] In this embodiment, the fixing part 332 can be located between the first side 3131 of the fixed window glass 31 and the mounting part 321 of the guide rail 32. At least part of the fixing part 332 is located within the first clearance groove 3213 of the guide rail 32. The fixing part 332 of the injection molded body 33 is formed during the integral injection molding process of the injection molded body 33 and the fixed window glass 31. The integral injection molding connection avoids the problem of loose joint or misalignment that may occur during subsequent assembly, thereby making the connection between the fixing part 332 and the fixed window glass 31 tighter. Moreover, during the integral injection molding process, the injection molded body 33 is formed directly on the periphery of the fixed window glass 31. The connection surface between the injection molded body 33 and the fixed window glass 31 is subjected to balanced force, reducing the area of ​​stress concentration, thereby making the connection between the injection molded body 33 and the fixed window glass 31 more stable. Since the connection strength between the injection molded body 33 and the fixed window glass 31 is high and the connection position is relatively tight, there are basically no gaps between the injection molded body 33 and the fixed window glass 31.

[0070] The aforementioned fixing part 332 is located between the second side surface 3132 and the guide mounting part 321, indicating that the fixing part 332 is connected to the inner surface 311 between the mounting part 321 and the second side surface 3132.

[0071] Since the guide rail 32 is bonded to the fixed window glass 31 via adhesive 40, the quality of the adhesive 40 affects the connection strength between the guide rail 32 and the fixed window glass 31. Over time, the adhesive 40 may age, harden, and crack due to ultraviolet radiation, temperature changes, etc., thus losing its sealing function. If the guide rail 32 and the fixed window glass 31 are not positioned correctly or the pressure is uneven during installation, gaps may exist between the adhesive 40 and the fixed window glass 31 or the guide rail 32, leading to seal failure. Under the continuous action of wind pressure or water flow, water may gradually penetrate the adhesive 40 and enter the vehicle interior.

[0072] In this embodiment, by positioning the fixing portion 332 of the injection-molded body 33 on the side of the mounting portion 321 facing the edge of the fixed window glass 31, water flow can be blocked on the first side 3131 of the fixing portion 332 facing the fixed window glass 31 after passing through the gap between the seal 34 and the fixed window glass 31. This prevents water from flowing through the gap between the fixing portion 332 and the fixed window glass 31, thereby preventing water from entering the vehicle through the gap between the mounting portion 321 of the guide rail 32 and the fixed window glass 31. This protects the vehicle's electrical system and interior trim from damage by water flow.

[0073] The blocking portion 333 is connected to the Z-direction-oriented end of the fixing portion 332 and is located on the side of the fixing portion 332 opposite to the fixed window glass 31. At least a portion of the blocking portion 333 is located between the guide portion 322 and the inner surface 311 of the fixed window glass 31. The blocking portion 333 protrudes relative to the first side surface 3131.

[0074] Specifically, the blocking part 333 includes a first segment 3331 and a second segment 3332. The first segment 3331 and the second segment 3332 are bent and connected. The side of the first segment 3331 opposite to the second segment 3332 is connected to the surface of the fixing part 332 opposite to the fixed window glass 31. Part of the first segment 3331 is located in the second clearance groove 3215 of the mounting part. The first segment 3331 extends in the Y direction, and the second segment 3332 extends in the X direction. The first segment 3331, the second segment 3332, and the side of the fixing part 332 opposite to the fixed window glass 31 form a drainage groove 3333. The orthogonal projection of the second segment 3332 onto the fixed window glass 31 covers the first side 3131 facing the roof.

[0075] In actual use, the seal 34 will abut against the first side 3131 of the fixed window glass 31. When the seal 34 is damaged by aging or cracking, the sealing performance of the seal 34 will decrease, resulting in a gap between the seal 34 and the fixed window glass 31. This makes it easy for water or dust to enter the interior of the vehicle 100 through the gap between the seal 34 and the fixed window glass 31.

[0076] In this embodiment, the structure assembled at the junction of the second side 3132 and the first side 3131 of the fixed window glass 31 is relatively complex. The seal 34, injection molded body 33, guide rail 32, and the vehicle body sheet metal 11 of the vehicle 100 all intersect at this point. The gaps between these components are easily penetrated by water, leading to water ingress into the vehicle 100. When water enters through the gap between the first side 3131 and the seal 34, it can reach the blocking part 333 and be blocked by the channel wall of the drainage groove 3333 of the blocking part 333. The water can then flow downwards along the drainage groove 3333, thereby preventing water from entering the vehicle interior.

[0077] Alternatively, under water pressure, water can flow from the gap between the seal 34 and the fixed window glass 31 to the wall of the drainage channel 3333, then bypass the first section 3331 and the second section 3332 of the blocking part 333, flowing from the second section 3332 towards the surface of the guide rail 32, and flowing towards the guide part 322 of the guide rail 32 towards the roof. In this case, the water flow path is relatively long. Therefore, when the water reaches the guide part 322 of the guide rail 32, the water flow force is relatively small, and the water flow force is basically insufficient to support the water flow to continue flowing upward along the surface of the guide part 322. At this time, the water flow may flow downward along the surface of the guide part 322 under the action of gravity, and flow out of the vehicle through the door. Ultimately, this achieves the effect of preventing water from entering the vehicle from the edge of the fixed window glass 31, improving the sealing performance of the glass assembly 30.

[0078] The second clearance groove 3215 provides installation space for the blocking part 333, allowing the first segment 3331 of the blocking part 333 to be located within the second clearance groove 3215. This ensures that the first segment 3331 of the blocking part 333 is as far away as possible from the first side 3131 of the fixed window glass 31, further extending the flow path of the water flowing over the fixed part 332 to the first segment 3331 of the blocking part 333. As the water flows along the flow path, the impact force of the water gradually decreases. After reaching the first segment 3331 of the blocking part 333, the water flowing towards the second segment 3332 of the blocking part 333 may lose its impact force, thus flowing downward along the surface of the guide part 322 under the action of gravity and flowing out of the vehicle.

[0079] Please see Figure 7 , Figure 7 yes Figure 5 The diagram shows a partial structural schematic of the injection-molded body 33. An extension 334 is connected to the side of the blocking portion 333 facing away from the seal 34 and extends away from the fixed window glass 31. The extension 334 is used to fit against the body sheet metal 11. Specifically, the extension 334 is connected to the side of the second segment 3332 facing the Z direction, and the extension 334 is bent and connected to the second segment 3332.

[0080] In this embodiment, after the glass assembly 30 is installed on the vehicle body 10, the extension 334 can abut against the top sheet metal of the body sheet metal 11, thereby reducing the gap between the glass assembly 30 and the body sheet metal 11, reducing the possibility of water flowing into the vehicle through the gap between the glass assembly 30 and the body sheet metal 11, and improving the sealing performance of the glass assembly 30.

[0081] The snap-fit ​​part 335 can be stepped. Please refer to the following: Figure 6The snap-fit ​​portion 335 is connected to the side of the fixing portion 332 facing the X direction. That is, the snap-fit ​​portion 335 is connected to the fixing portion 332 and extends away from the mounting portion 321. The snap-fit ​​portion 335 protrudes relative to the first side surface 3131.

[0082] Please refer to the following: Figure 8 and Figure 9 , Figure 8 yes Figure 2 The diagram shows the structure of the seal 34. Figure 9 yes Figure 8 The diagram shows a cross-sectional view of the seal 34 at point BB. The seal 34 includes a sealing body 341, a second limiting body 342, a lip 343, and a protrusion 344. The sealing body 341 has a guide groove 3411, the opening of which is located on one side surface of the sealing body 341 in the width direction. The guide groove 3411 is used for sliding of the lift window 20. The second limiting body 342 is connected to the other side surface of the sealing body 341 in the width direction. The lip 343 is connected to one side of the sealing body 341 in the thickness direction. The lip 343 is bent and connected to the sealing body 341, forming a limiting groove 245 at the connection point. The protrusion 344 is connected to both sides of the sealing body 341 in the thickness direction. Specifically, the protrusion 344 may include four protrusions, two of which are located on the surface of the sealing body 341 facing the interior of the vehicle, and the other two are located on the surface of the sealing body 341 facing the exterior of the vehicle. Each protrusion extends along the Z direction on the surface of the sealing body 341.

[0083] The sealing body 341 of a portion of the seal 34 is located within the snap-fit ​​groove 3212 of the mounting portion 321 of the guide rail 32. The second limiting body 342 and the first limiting body 3214 mutually limit each other. The opening of the guide groove 3411 of the sealing body 341 faces the opening of the snap-fit ​​groove 3212 of the mounting portion 321 of the guide rail 32. A portion of the sealing body 341 extends from the opening of the snap-fit ​​groove 3212 of the mounting portion 321 and covers a portion of the guide portion 322 of the guide rail 32 facing the outside of the vehicle. A protrusion abuts between the sealing body 341 and the guide portion 322 of the guide rail 32. The portion of the groove wall of the limiting groove 245 of the seal 34 facing the roof of the vehicle is connected to the snap-fit ​​portion 335 of the injection molded body 33. The portion of the groove wall of the limiting groove 245 of the seal 34 facing the bottom of the vehicle is connected to the edge of the mounting portion 321 of the guide rail 32.

[0084] The end of the sealing body 341 facing the roof is located inside the drainage groove 3333. The protrusion 344 at the end of the sealing body 341 is connected to the surface of the sealing body 341 facing the groove wall of the drainage groove 3333, so that the protrusion 344 abuts against the groove wall of the drainage groove 3333.

[0085] In this embodiment, the protrusion 344 can seal the gap between the sealing body 341 and the guide rail 32, and the gap between the sealing body 341 and the injection molded body 33, so as to minimize the flow of water between the sealing body 341 and the guide rail 32, and between the sealing body 341 and the injection molded body 33.

[0086] Please refer to the following: Figure 10 , Figure 10 yes Figure 2 This diagram illustrates the water flow direction in the assembly structure of the fixed window glass 31, injection molded body 33, and guide rail 32. When the vehicle 100 is used in rainy weather or during car washing, where the water impact is significant, some water may intrude into the vehicle through the gap between the first side 3131 and the seal 34. The impact force of the water flowing through the gap between the first side 3131 and the seal 34 is reduced. Because the locking part 335 protrudes relative to the first side 3131, it can block some of the water intruding from the external environment. The locking part 335 can extend the path of the water intruding into the vehicle, thus continuously reducing the impact force of the water along its flow path. Under the influence of gravity, the water can flow along the surface of the locking part 335 towards the outside of the vehicle towards the bottom, and ultimately flow through the outer surface of the vehicle body 10 to the external environment.

[0087] Another portion of the water flow may infiltrate through the gap between the end of the first connecting portion 331 of the injection molded body 33 and the seal 34, and flow towards the blocking portion 333. The water flow can continue to seep into the vehicle through the gap between the first section 3331 of the blocking portion 333 and the seal 34. Since the first section 3331 is recessed relative to the first side 3131 of the fixed window glass 31, the water flow flows from the first side 3131 around the fixing portion 332 towards the surface inside the vehicle and then flows to the first section 3331. During the flow, the impact force of the water flow continuously decreases. The water flow may lose its impact force during the flow from the first section 3331 to the second section 3332, and thus flow towards the bottom of the vehicle along the seal 34 under the action of gravity.

[0088] Please refer to the following: Figure 11 , Figure 11 yes Figure 10This is a schematic diagram showing another angle of the water flow direction of the injection molded body 33 and the mounting part 321. The mounting part 321 of the guide rail 32 is located within the clearance notch 3311 of the injection molded body 33. There is a height difference D1 between the top of the mounting part 321 and the bottom of the blocking part 333. The top of the mounting part 321 is located on the side of the bottom of the blocking part 333 facing the roof. After the external water flows through the blocking part 333, the fixing part 332, and the snap-fit ​​part 335 of the injection molded body 33, the impact force of the water flow is reduced. Generally, it flows downward along the seal 34 under the action of gravity and is unlikely to flow past the top of the mounting part 321 into the vehicle interior. The water flow can eventually flow through the outer surface of the vehicle body 10 to the external environment, thus achieving a waterproofing effect. Even if a small portion of the water flows upward through the gap between the second section 3332 of the blocking part 333 and the guide part 322 of the guide rail 32, and flows into the clearance gap 3311, the abutment block 3312 between the mounting part 321 and the first connecting part 331 can further block the water flow, preventing the water from entering the interior of the vehicle 100 through the gap between the mounting part 321 and the first connecting part 331.
