Description

Technical Field

[0001] This application relates to the field of vehicle manufacturing technology, and in particular to a zero-step difference window glass guide rail structure, system, assembly method and vehicle thereof. Background Technology

[0002] In vehicles, zero-step difference windows generally refer to windows where there is no surface difference between the window glass and the door pillar, which can effectively reduce wind resistance and noise during vehicle operation.

[0003] The zero-step differential window glass guide rail structure is one of the key components of a zero-step differential window. It mainly consists of two guide rails, referred to as the upper and lower rails. These rails are assembled along the height of the vehicle, with the upper rail mounted on the door pillar and the lower rail located inside the door. During assembly, the lower rail is typically installed inside the door first, followed by the glass. Because the lower rail is inside the door, the glass assembly is essentially blind-mounted, making it difficult and inefficient. Summary of the Invention

[0004] Therefore, it is necessary to provide a zero-step difference window glass guide rail structure, system, assembly method, and vehicle that enables simple, precise, and efficient assembly of vehicle window glass.

[0005] To solve the above-mentioned technical problems, this application provides the following technical solution:

[0006] A zero-step difference vehicle window glass guide rail structure includes a first guide rail and a second guide rail. The first guide rail is located below the second guide rail in the height direction of the vehicle. In the width direction of the vehicle, both the first guide rail and the second guide rail have inner and outer sides that are arranged opposite to each other, and both are provided with glass guide grooves for installing and limiting glass sealing strips.

[0007] The zero-step difference window glass guide rail structure further includes a first extension section and a second extension section. The first extension section is located at one end of the first guide rail near the second guide rail and is situated inside the first guide rail. The second extension section is located at one end of the second guide rail near the first guide rail and is situated outside the second guide rail.

[0008] The first guide rail has a first clearance cut on the outer side of the end where the first extension is located, and the second guide rail has a second clearance cut on the inner side of the end where the second extension is located. The first clearance cut is used to avoid external water cutting and to allow the second extension to extend in, while the second clearance cut is used to allow the first extension to extend in.

[0009] In one embodiment, the first avoidance cut includes a first cut and a second cut that are interconnected, and the second avoidance cut includes a third cut and a fourth cut that are interconnected.

[0010] The first cut and the third cut are positioned opposite each other in the width direction of the vehicle, and the second cut and the fourth cut are positioned correspondingly in the length direction of the vehicle to form an avoidance groove.

[0011] Understandably, the clearance groove creates a hollowed-out groove on one side of the connection transition area between the first and second guide rails along the vehicle's length. This allows only the glass sealing strip to be present at that location. When the glass bracket moves to this connection transition area, the clearance groove releases a limit on the glass bracket in the vehicle's width direction, reducing the resistance and limiting the glass bracket's movement. This compensates for assembly errors in the vehicle's length direction, allowing the glass bracket to smoothly pass through the connection transition area between the first and second guide rails, preventing jamming.

[0012] In one embodiment, the first guide rail includes a first body and a first stop bar, the first body having the glass guide groove, the glass guide groove having an opening on one side in the length direction of the vehicle;

[0013] Along the width direction of the vehicle, the first stop bar is located on one side of the opening and extends outward from the first guide rail, forming a first limiting step between it and the first body. The first limiting step is used to abut against and limit the glass sealing strip in the length direction of the vehicle.

[0014] Understandably, the first limiting step limits the glass sealing strip to prevent it from wobbling or detaching along the length of the vehicle when the window glass is raised or lowered, thus affecting the user experience.

[0015] In one embodiment, the first guide rail further includes a second stop bar. Along the width direction of the vehicle, the second stop bar is located on the other side of the opening and connected to the first body. The second stop bar is recessed into the glass guide groove relative to the first body to form a first limiting surface in the width direction of the vehicle for abutting and limiting the glass sealing strip.

[0016] Furthermore, a second limiting step is formed between the second stop bar and the first body to limit the glass sealing strip in the longitudinal direction of the vehicle.

[0017] Understandably, the second limiting step, in conjunction with the second stop bar, can limit the glass sealing strip in both the length and width directions of the vehicle, thereby further ensuring the stability of the glass sealing strip installation.

[0018] In one embodiment, in the length direction of the vehicle, the end of the second stop bar away from the first body is provided with an extension section, the extension section being bent outward relative to the second stop bar towards the first guide rail to form a blocking part, the blocking part being used to limit and abut against the glass sealing strip in the length direction of the vehicle.

[0019] In one embodiment, the second guide rail includes a second body and a third stop bar. The second body is provided with the glass guide groove and the opening. The glass guide groove has an opening on one side in the length direction of the vehicle.

[0020] Along the width direction of the vehicle, the third stop is located on one side of the opening and extends outward to the second guide rail, forming a third limiting step between the third stop and the second body. The third limiting step is used to limit the glass sealing strip in the length direction of the vehicle.

[0021] Understandably, the formed third limiting step can prevent the glass sealing strip from being abutted and limited in the length direction of the vehicle, thus preventing the window glass from detaching from the glass guide channel.

[0022] In one embodiment, the second guide rail further includes a folding plate, which is located on the other side of the opening and connected to the second body along the vehicle width direction. The end of the folding plate away from the second body is bent and extends into the glass guide groove, forming a fourth limiting step between the glass guide groove and the inner wall of the glass guide groove.

[0023] The folding plate on the surface in the vehicle width direction is used to limit the glass sealing strip in the vehicle width direction, and the fourth limiting step is used to limit the glass sealing strip in the vehicle length direction.

[0024] Understandably, the folding plate, in conjunction with the third stop bar, further limits the glass sealing strip on the second guide rail, thereby improving the stability of the glass sealing strip installation.

[0025] In one embodiment, the first extension segment is integral with the first guide rail; and / or, the second extension segment is integral with the second guide rail.

[0026] Understandably, the integrated design reduces the connection structure between the first extension section and the first guide rail, and between the second extension section and the second guide rail, making the connection between components more stable.

[0027] This application also provides the following technical solutions:

[0028] A zero-step difference vehicle window glass guide rail system includes a vehicle window glass, a glass sealing strip, and a zero-step difference vehicle window glass guide rail structure as described in any of the above embodiments.

[0029] The glass sealing strip is located within the glass guide groove through the opening, and the window glass is slidably connected to the glass sealing strip.

[0030] This application also provides the following technical solutions:

[0031] A method for assembling zero-step difference vehicle window glass, based on the zero-step difference vehicle window glass guide rail system in the above embodiment, includes the following steps:

[0032] The first guide rail is installed on the door panel, and the first extension section protrudes from the outer water cut of the door panel in the height direction of the vehicle through the first avoidance cut and the second avoidance cut, so that the first extension section is exposed.

[0033] A portion of the glass sealing strip is installed into the glass guide groove on the first guide rail;

[0034] Guided by the first extension section, the glass bracket is guided and assembled with the first guide rail;

[0035] The second guide rail is installed to the door panel, and the first extension extends into the second clearance cut, and the second extension extends into the first clearance cut.

[0036] Install the other part of the glass sealing strip into the glass guide groove on the second guide rail.

[0037] This application also provides the following technical solutions:

[0038] A vehicle including a zero-step differential window glass guide rail system as described in the above embodiments.

[0039] Compared with existing technologies, the aforementioned zero-step differential window glass guide rail structure, system, assembly method, and vehicle utilize a first extension section, a second extension section, a first clearance cut, and a second clearance cut. This allows the first extension section to extend along the vehicle's height to the outside of the outer waterline, serving as a visible portion. This visible portion provides guidance and prompts, eliminating blind operation during window glass assembly. Furthermore, due to the presence of the first extension section, during window glass assembly, simply placing the window glass against the first extension section and guiding it allows for easy insertion into the glass sealing strip, making assembly more convenient and efficient. Simultaneously, the cooperation between the first extension section and the second clearance cut, and the cooperation between the second extension section and the first extension section, ensures precise assembly of both the first and second guide rails.

[0072] Please see Figures 1 to 4This application provides a zero-step differential window glass guide rail system 200, which includes a window glass 201, a glass sealing strip 202, a zero-step differential window glass guide rail structure 100, and a door panel 203. The zero-step differential window glass guide rail structure 100 is installed on the door panel 203, the glass sealing strip 202 is installed on the zero-step differential window glass guide rail structure 100, and a glass bracket 2011 is provided on the window glass 201. The glass bracket 2011 extends into the glass sealing strip 202, wherein the glass bracket 2011 is slidably connected to the glass sealing strip 202 and moves up and down under the guidance of the zero-step differential window glass guide rail structure 100 to realize the smooth raising and lowering of the window glass 201.

[0073] Here, for reference Figure 2 The door panel 203 includes a body 2031 and a door pillar 2032. The door pillar 2032 is installed on the body 2031 and can be integrally formed with the body 2031.

[0074] This is not the only part; please continue to refer to other resources. Figure 2 The zero-step differential window glass guide system 200 also includes structures such as an inner door pillar trim panel 204 and an outer door pillar trim panel 205. In the vehicle's width direction y, the inner door pillar trim panel 204 is installed on the inner side of the door pillar 2032 for interior decoration. The outer door pillar trim panel 205 covers the outer side of the door pillar 2032. Furthermore, in the vehicle's width direction y, the outer surface of the outer door pillar trim panel 205 is flush with the outer surface of the window glass 201 to achieve a zero-step differential window.

[0075] Furthermore, such as Figure 6 , Figures 12 to 16 As shown, the glass bracket 2011 includes a frame 2012 and a limiting block 2013. Along the length x direction of the vehicle, the frame 2012 has a first side 2014 and a second side 2015 disposed opposite to each other. The first side 2014 is installed on the window glass 201. Specifically, the first side 2014 can be connected to the window glass 201 by adhesive or screw. The second side 2015 is used to extend into the glass sealing strip 202 and slide within the glass sealing strip 202. The limiting block 2013 is disposed on the side of the second side 2015 in the width y direction of the vehicle and protrudes outward. The limiting block 2013 is used to limit and abut against the glass sealing strip 202 in the length x and width y directions of the vehicle and to slide within the glass sealing strip 202.

[0076] For ease of explanation, this application is based on the three-dimensional coordinates of the vehicle. The length direction of the vehicle is defined as the x-direction, the width direction as the y-direction, and the height direction as the z-direction. The inner and outer sides of the vehicle are defined with reference to the driver's cab. The interior of the driver's cab is the inner side of the vehicle, and the exterior of the driver's cab is the outer side of the vehicle.

[0077] like Figures 2 to 11 As shown, the zero-step window glass guide rail structure 100 includes a first guide rail 10, a second guide rail 20, a first extension section 30, and a second extension section 40. The first guide rail 10 is located below the second guide rail 20 in the vehicle's height direction z. In the vehicle's width direction y, both the first guide rail 10 and the second guide rail 20 have inner sides 101 and outer sides 102 arranged opposite to each other, and both have glass guide grooves 103 for installing glass sealing strips 202. The first extension section 30 is located at one end of the first guide rail 10 near the second guide rail 20 and is located at the first extension section 40. The first guide rail 10 has an inner side 101; a second extension 40 is located at one end of the second guide rail 20 near the first guide rail 10 and at the outer side 102 of the second guide rail 20; wherein, the first guide rail 10 has a first clearance cut 11 on the outer side 102 where the first extension 30 is located, and the second guide rail 20 has a second clearance cut 21 on the inner side 101 where the second extension 40 is located; the first clearance cut 11 is used to avoid the outer water cut and allows the second extension 40 to extend into it, and the second clearance cut 21 allows the first extension 30 to extend into it. It can be understood that by setting the first extension 30, the second extension 40, the first clearance cut 11, and the second clearance cut 21, the first extension 30 can extend along the height direction z of the vehicle to the outside of the outer water cut to be visible as a visible part. The visual part can serve as a prompt and guide, so that the assembly of the window glass 201 is no longer a blind operation; and, due to the presence of the first extension section 30, when assembling the window glass 201, it is only necessary to place the window glass 201 against the first extension section 30 and insert it into the glass sealing strip 202 under the guidance of the first extension section 30, making the assembly more convenient and efficient; at the same time, the first extension section 30 cooperates with the first clearance cut 11, and the second extension section 40 cooperates with the second clearance cut 21, so that the first guide rail 10 and the second guide rail 20 can also be accurately assembled.

[0078] Preferably, the first guide rail 10 is installed inside the body 2031, and the second guide rail 20 is installed on the doorpost 2032.

[0079] Here, the outer water cutter refers to the sealing strip located between the window glass 201 and the door panel 203, with the outer portion being called the outer water cutter. Its main function is to scrape away water droplets, water mist, and dust from the glass surface when the window glass 201 is raised or lowered, ensuring clear driving visibility and enhancing the vehicle's aesthetics. Additionally, the glass sealing strip 202 is confined within the glass guide groove 103, and the window glass 201 and the glass sealing strip 202 are slidably connected.

[0080] Further, please refer to Figure 9 and Figure 10The first clearance cut 11 includes a first cut 111 and a second cut 112 that are interconnected, and the second clearance cut 21 includes a third cut 211 and a fourth cut 212 that are interconnected; wherein, the first cut 111 and the third cut 211 are arranged opposite to each other in the width direction y of the vehicle, and the second cut 112 and the fourth cut 212 are arranged correspondingly in the length direction x of the vehicle and form a clearance slot 104.

[0081] It should be explained that both the first guide rail 10 and the second guide rail 20 are mounted on the same door panel 203 (located on the same mounting surface in the width direction of the vehicle). Therefore, the mating area of ​​the first guide rail 10 and the second guide rail 20 generally will not be misaligned or the error will be within the allowable range in the width direction y of the vehicle. However, due to assembly errors, the mating area of ​​the first guide rail 10 and the second guide rail 20 may be misaligned in the length direction x of the vehicle. At this time, during the raising and lowering of the window glass 201, when the glass bracket 2011 moves to the mating area of ​​the two guide rails, that is, when it moves to the transition area connecting the first guide rail 10 and the second guide rail 20, the limiting block 2013 will swing in the front and rear directions of the vehicle due to the different forces caused by this misalignment. At this time, the window glass 201 is more likely to tilt relative to the height direction z of the vehicle, resulting in jamming and affecting the user experience. In this application, the avoidance groove 104 formed by the second cut 112 and the fourth cut 212 in the vehicle's length x direction creates a hollow space on one side of the connection transition area between the first guide rail 10 and the second guide rail 20 in the vehicle's length x direction. In this way, only the glass sealing strip 202 exists at this position. When the glass bracket 2011 moves to this connection transition area, the avoidance groove 104 releases a limit on the glass bracket 2011 in the length x direction, thereby reducing the resistance and limiting of the glass bracket 2011 and compensating for the assembly error between the two in the vehicle's length x direction. This allows the glass bracket 2011 to pass smoothly through the connection transition area between the first guide rail 10 and the second guide rail 20, preventing the window glass 201 from getting stuck during the lifting and lowering process.

[0082] Specifically, such as Figure 5 and Figure 6 As shown, both the first guide rail 10 and the second guide rail 20 have openings 105 in the longitudinal direction x of the vehicle, and the openings 105 communicate with the glass guide groove 103. In the longitudinal direction x of the vehicle, the vehicle has a front end and a rear end. The openings 105 face the front end, and a portion of the glass sealing strip 202 is installed within the glass guide groove 103 through the openings 105. The first cut 111 is located on the inner side 101 of the vehicle, the third cut 211 is located on the outer side 102 of the vehicle, and the second cut 112 and the fourth cut 212 face the rear end of the vehicle.

[0083] like Figure 5As shown, the first guide rail 10 includes a first body 12 and a first stop bar 13. The first body 12 has the aforementioned glass guide groove 103. Along the vehicle width direction y, the first stop bar 13 is located on one side of the opening 105 and extends outward 102 of the first guide rail 10, forming a first limiting step 14 between itself and the first body 12. The first limiting step 14 is used to abut against the limiting glass sealing strip 202 in the vehicle length direction x, thereby preventing the glass sealing strip 202 from detaching from the opening 105. The limiting block 2013 abuts against the glass sealing strip 202 at the location of the first limiting step 14, which is equivalent to also abutting against the first limiting step 14 at that location.

[0084] Preferably, the first body 12 is arranged in a "C" or "U" shape. The opening of the "C" or "U" shape is the opening 105.

[0085] For further information, please continue to refer to [link / reference]. Figure 5 The first guide rail 10 also includes a second stop bar 15, which is located on the other side of the opening 105 and connected to the first body 12. The second stop bar 15 is recessed into the glass guide groove 103 relative to the first body 12 to form a first limiting surface 151 in the width direction y of the vehicle for abutting against and limiting the glass sealing strip 202. Furthermore, a second limiting step 152 is formed between the second stop bar 15 and the first body 12 for limiting the glass sealing strip 202 in the length direction x of the vehicle. Thus, the second limiting step 152 can cooperate with the second stop bar 15 to limit the glass sealing strip 202 in both the length direction x and the width direction y of the vehicle, thereby further ensuring the stability of the glass sealing strip 202 installation.

[0086] It should be explained that the glass sealing strip 202 is installed inside the glass guide groove 103, and its main function is sealing. The outer contour of the portion of the glass sealing strip 202 installed inside the glass guide groove 103 basically matches the inner contour of the glass guide groove 103. The limiting block 2013 is inside the glass guide groove 103. At this time, in the x-direction of the vehicle, the limiting block 2013 is also equivalent to abutting against the first limiting step 14 for limiting. In the y-direction of the vehicle, the limiting block 2013 is also equivalent to abutting against the first limiting surface 151 for limiting. At the same time, the limiting block 2013 also abuts against other groove walls inside the glass guide groove 103, thereby achieving the limiting of the limiting block 2013 inside the glass guide groove 103 (the length direction x and the width direction y of the vehicle).

[0087] Furthermore, such as Figure 5As shown, in the vehicle's length direction x, the end of the second stop bar 15 away from the first main body 12 is provided with an extension section 153. The extension section 153 bends outward relative to the second stop bar 15 towards the first guide rail 10 to form a blocking part 154. The blocking part 154 is used to limit and abut against the glass sealing strip 202 in the vehicle's length direction x. In this way, the glass sealing strip 202 is further limited.

[0088] Please see Figure 6 The second guide rail 20 includes a second body 22 and a third stop bar 23. The second body 22 also has the aforementioned glass guide groove 103 and opening 105. Along the vehicle width direction y, the third stop bar 23 is located on one side of the opening 105 and extends outward from the second guide rail 20, forming a third limiting step 24 between itself and the second body 22. The third limiting step 24 is used to limit the glass sealing strip 202 in the vehicle length direction x. Thus, the formed third limiting step 24 can abut and limit the glass sealing strip 202 in the vehicle length direction x, preventing the window glass 201 from detaching from the glass guide groove 103 through the opening 105. Similarly, referring to the function of the first limiting step 14, when the limiting block 2013 is in the glass guide groove 103 on the second body 22, in the vehicle length direction x, the limiting block 2013 is also equivalent to abutting and limiting the third limiting step 24. Furthermore, in the length direction x of the vehicle, the groove wall of the glass guide groove 103 away from the opening 105 also forms a limiting abutment with the limiting block 2013, thereby achieving the front and rear limiting of the limiting block 2013 in the length direction x of the vehicle within the second guide rail 20.

[0089] Preferably, the second body 22 is arranged in a "C" or "U" shape. The opening of the "C" or "U" shape is the opening 105.

[0090] In one embodiment, please continue to refer to Figure 6 The second guide rail 20 also includes a folded plate 25. Along the vehicle width direction y, the folded plate 25 is located on the other side of the opening 105 and connected to the second body 22. The end of the folded plate 25 away from the second body 22 is bent and extends into the glass guide groove 103, forming a fourth limiting step 26 between it and the inner wall of the glass guide groove 103. The folded plate 25 on the surface in the vehicle width direction y is used to limit the glass sealing strip 202 in the vehicle width direction y, and the fourth limiting step 26 is used to limit the glass sealing strip 202 in the vehicle length direction x. Thus, the folded plate 25, in conjunction with the third stop 23, can further limit the glass sealing strip 202 on the second guide rail 20, thereby improving the stability of the glass sealing strip 202 installation.

[0091] Furthermore, in the width direction y of the vehicle, the second side 2015 of the frame 2012 has a protrusion 2016 on the side opposite to the limiting block 2013. The protrusion 2016 abuts against the surface of the folding plate 25 in the width direction y of the vehicle, thus limiting its movement. Also, in the width direction y of the vehicle, the side of the limiting block 2013 opposite to the frame 2012 abuts against the inner wall of the glass guide channel 103. Thus, within the second guide rail 20, the protrusion 2016 and the limiting block 2013 limit the frame 2012 in the width direction y of the vehicle, preventing it from swaying.

[0092] Similarly, since the second side 2015 extends into the glass sealing strip 202, the protrusion 2016 and the limiting block 2013 indirectly abut against the second body 22 in the width direction y of the vehicle through the glass sealing strip 202 to achieve their limiting.

[0093] Please continue to refer to this. Figure 4 and Figure 5 The first extension section 30 and the first guide rail 10 are configured as one piece; and / or, the second extension section 40 and the second guide rail 20 are configured as one piece. It is understood that the one-piece configuration can reduce the connection structure between the first extension section 30 and the first guide rail 10, and between the second extension section 40 and the second guide rail 20, making the connection between the components of the zero-step window glass guide rail structure 100 more stable.

[0094] Here, the first extension section 30 and the first guide rail 10 can be integrally formed by rolling or extrusion, and the second extension section 40 and the second guide rail 20 can be integrally formed.

[0095] In one embodiment, please refer to Figure 6 as well as Figures 12 to 16 These figures illustrate in detail the installation relationship between the window glass 201 and the glass bracket 2011, as well as the specific structure of the limiting block 2013.

[0096] Specifically, the limiting block 2013 includes a first rigid block 441 and a first elastic block 442. The first rigid block 441 is located on the side of the second side 2015 in the width direction y of the vehicle and protrudes outwards. The first rigid block 441 abuts against one wall of the glass guide channel 103 in the width direction y of the vehicle, providing a limiting effect. The first rigid block 441 forms a rigid limiting step 443 between one side of the first rigid block 441 in the length direction x of the vehicle and the frame 2012. The rigid limiting step 443 rigidly abuts against the glass sealing strip 202 in the length direction x of the vehicle, that is, it is limited by the first limiting step 14 or the third limiting step 24. The first elastic block 442 is located on the other side of the first rigid block 441 in the length direction x of the vehicle and protrudes outwards. The first elastic block 442 elastically abuts against the wall of the glass guide channel 103 in the width direction y of the vehicle, away from the opening 105, providing a limiting effect. That is, both the rigid limiting step 443 and the first elastic block 442 are engaged with corresponding structural limiting mechanisms. It should be explained that by setting the first elastic block 442 and forming the rigid limiting step 443, the second side 2015 is limited in the x-direction of the vehicle's length using the rigid limiting step 443 and the first elastic block 442. Because the first elastic block 442 has elastic deformation capability, it can provide a certain deformable space in the length direction of the vehicle, thereby providing support and structural release space for spatial deformation and side-to-side movement caused by external forces such as size or lifting / turning, effectively preventing the window glass from jamming.

[0097] Meanwhile, in conjunction with the setting of the clearance slot 104, as the window glass 201 rises and falls, when the limiting block 2013 moves to the connection transition area of ​​the first guide rail 10 and the second guide rail 20, the limiting effect of the first elastic block 442 at this position will be weakened, thereby weakening the limiting of the glass bracket 2011 in the vehicle length direction x.

[0098] Please continue to refer to this. Figures 12 to 15 The first elastic block 442 is arc-shaped, and a hollow groove 444 is formed between the arc-shaped first elastic block 442 and the first rigid block 441. It can be understood that the arc shape of the first elastic block 442 can reduce the contact area between it and the glass sealing strip 202, thereby reducing the frictional resistance between the two and ensuring the smoothness of the raising and lowering of the window glass 201. The arc-shaped first elastic block 442 has good buffering capacity, so that when the limiting block 2013 is subjected to external force, it can absorb and disperse part of the force through its own deformation. At the same time, the hollow groove 444 makes the first elastic block 442 more flexible, so that the first elastic block 442 has better deformable space when subjected to external force. Combined with the support and limiting function of the first rigid block 441, the glass bracket 2011 can play its supporting role while having good tolerance.

[0099] Furthermore, such as Figure 16 and Figure 17 As shown, the first elastic block 442 includes an arc-shaped segment 4421 and a straight segment 4422. One end of the arc-shaped segment 4421 is connected to the first rigid block 441, and the other end is suspended relative to the first rigid block 441. The straight segment 4422 is connected to the suspended end of the arc-shaped segment 4421 and forms a hollow groove 444 with the first rigid block 441, which is used to elastically abut against the glass sealing strip 202 in the length x direction of the vehicle. Here, the arc-shaped segment 4421 has a longer elastic deformation capacity, which makes the applicable space of the first elastic block 442 larger. The straight segment 4422 can increase the contact area between the first elastic block 442 and the glass sealing strip 202, thereby increasing the stability of the glass bracket 2011 supporting the window glass 201 and making the movement of the window glass 201 more stable.

[0100] In one embodiment, such as Figure 17 As shown, the length of the straight segment 4422 is L, where L ≥ 2mm. Here, the length of the straight segment 4422 should not be too small. A longer straight segment 4422 can ensure that the first elastic block 442 has sufficient contact area with the first elastic block 442, thereby improving the stability of the glass bracket 2011 in supporting the car window glass 201.

[0101] Specifically, the length L of the straight line segment 4422 can be 2mm, 3mm, 5mm, or other values. The specific value of the length L of the straight line segment 4422 can be determined according to the actual situation and is not limited here. In this embodiment, the length L of the straight line segment 4422 is set to 2mm.

[0102] In one embodiment, the arc-shaped segment 4421 and the first rigid block 441 are smoothly connected by an arc-shaped chamfer 4423. Here, the arc-shaped chamfer 4423 has a buffering effect. By smoothly connecting the first rigid block 441 and the arc-shaped segment 4421 through the arc-shaped chamfer 4423, a portion of the force can be absorbed and dispersed when the first elastic block 442 is suddenly subjected to force, thereby improving the reliability of the connection between the first elastic block 442 and the first rigid block 441 and preventing the connection structure from being damaged by force.

[0103] As a preferred option, such as Figure 15 As shown, the radius of the arc chamfer 4423 is R, where R ≥ 1 mm.

[0104] Here, the radius R of the curved chamfer can be 1mm, 1.5mm, 2mm, etc., and the specific value of the radius R can be determined according to the actual situation, without limitation. In this embodiment, the radius R of the curved chamfer is set to 1mm.

[0105] In one embodiment, such as Figure 16 and Figure 17As shown, the number of arc segments 4421 is set to two, and the two arc segments 4421 are symmetrically arranged with the straight segment 4422 as the axis of symmetry. One end of each arc segment 4421 is connected to the straight segment 4422, and the other end is smoothly connected to the first rigid block 441 through an arc chamfer.

[0106] Please refer to Figure 16. Along the length x of the vehicle, the maximum height of the hollow groove 444 is H, which is also the distance between the straight segment 4422 and the first rigid block. H ≥ 2mm. This ensures that the bufferable path of the first elastic block 442 is small enough to achieve its optimal buffering capacity, thus maximizing the deformation buffering capacity of the first elastic block 442.

[0107] Here, the maximum height H of the hollow groove 444 can be 2mm, 2.3mm, 2.6mm, 3mm, 3.5mm, etc. The specific value of the maximum height H of the hollow groove 444 can be determined according to the actual situation and is not limited here. In this embodiment, the maximum height H of the hollow groove 444 is set to 2mm.

[0108] like Figure 18 As shown, this application also provides a method for assembling zero-step difference vehicle window glass. This assembly method is based on the zero-step difference vehicle window glass guide rail system 200 in the above embodiments. Specifically, the assembly method includes the following steps:

[0109] Step S100: Install the first guide rail 10 on the door panel 203, and make the first extension section 30 protrude from the outer water cut on the door panel 203 in the height direction z of the vehicle by the avoidance of the first avoidance cut 11, so that the first extension section 30 is exposed.

[0110] Step S200: Install a portion of the glass sealing strip 202 into the glass guide groove 103 on the first guide rail 10;

[0111] Step S300: Guided by the first extension section 30, the glass bracket 2011 is guided and assembled with the first guide rail 10.

[0112] Step S400: Install the second guide rail 20 onto the door panel 203, and extend the first extension 30 into the second clearance cut 21 and the second extension 40 into the first clearance cut 11.

[0113] In step S500, the other part of the glass sealing strip 202 is installed into the glass guide groove 103 on the second guide rail 20.

[0114] As can be seen from the above steps, visualization can not only serve as an identifier and prompt for assembly, but also guide the installation of the glass bracket 2011 using the first extension section 30, thereby enabling the window glass 201 to be assembled smoothly and quickly, greatly improving assembly efficiency.

[0115] It should be understood that, unless otherwise specified in this document, there is no strict order to the above steps. These steps can be performed sequentially or in any other order, and the specific steps can be determined according to the actual situation.

[0116] This application also provides a vehicle including the zero-step differential window glass guide rail system 200 as described in the above embodiments.

[0117] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0118] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
