Description

Technical Field

[0001] The present application relates to the technical field of vehicle manufacturing, and particularly relates to a zero-step difference window glass guide rail structure, system, assembly method and vehicle thereof. Background Art

[0002] In a vehicle, a zero-step difference window generally means that there is no surface difference between the window glass and the door pillar of the door, so as to effectively reduce wind resistance and noise during vehicle driving.

[0003] The zero-step difference window glass guide rail structure is one of the important structures of the zero-step difference window. It mainly includes two guide rails, which are called the upper guide rail and the lower guide rail. The upper and lower guide rails are assembled along the height direction of the vehicle, and the upper guide rail is installed on the door pillar, and the lower guide rail is located inside the door. During the assembly process, generally, the lower guide rail is first installed inside the door and then the glass is assembled. Since the lower guide rail is inside the door, the assembly of the glass is a blind assembly, which is not only difficult to assemble but also has low efficiency. Summary of the Invention

[0004] Based on this, it is necessary to provide a zero-step difference window glass guide rail structure, system, assembly method and vehicle thereof that can make the assembly of window glass simple, accurate and efficient.

[0005] To solve the above technical problems, the present application provides the following technical solutions:

[0006] A zero-step difference 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 an inner side and an outer side that are opposite to each other, and both are provided with glass guide grooves for installing and limiting a glass sealing strip.

[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 provided at one end of the first guide rail close to the second guide rail and is located inside the first guide rail; the second extension section is provided at one end of the second guide rail close to the first guide rail and is located outside the second guide rail.

[0008] Wherein, a first avoidance notch is provided on the outer side of the first guide rail at the end where the first extension section is provided, and a second avoidance notch is provided on the inner side of the second guide rail at the end where the second extension section is provided; the first avoidance notch is used to avoid an outer water cut and allow the second extension section to extend therein, and the second avoidance notch allows the first extension section to extend therein.

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

[0010] Wherein, the first cut and the third cut are oppositely arranged in the width direction of the vehicle, and the second cut and the fourth cut are correspondingly arranged in the length direction of the vehicle and form an avoidance notch.

[0011] It can be understood that the formed avoidance notch forms a hollow groove on one side in the length direction of the vehicle at the connection transition area between the first guide rail and the second guide rail. In this way, only the glass sealing strip exists at this position. When the glass bracket moves to this connection transition area, the avoidance notch releases a limit on the glass bracket in the width direction of the vehicle to reduce the abutting limit on the glass bracket, thereby compensating for the assembly error between the two in the length direction of the vehicle, so that the glass bracket can smoothly pass through the connection transition area between the first guide rail and the second guide rail and avoid the occurrence of jamming.

[0012] In one embodiment, the first guide rail includes a first main body and a first retaining strip. The glass guide groove is formed on the first main body, and the glass guide groove has an opening on one side in the length direction of the vehicle;

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

[0014] It can be understood that the first limiting step limits the glass sealing strip, which can prevent the glass sealing strip from shaking or detaching in the length direction of the vehicle when the window glass moves up and down, affecting the user experience.

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

[0016] And, a second limiting step for limiting the glass sealing strip in the length direction of the vehicle is formed between the second retaining strip and the first main body.

[0017] It can be understood that the second limiting step can cooperate with the second retaining strip to limit the glass sealing strip in both the length direction and the width direction of the vehicle to further ensure the stability of the installation of the glass sealing strip.

[0018] In one embodiment, in the length direction of the vehicle, an extension section is provided at one end of the second baffle away from the first main body, and the extension section is bent toward the outer side of the first guide rail relative to the second baffle to form a blocking portion, and the blocking portion is used to limit the position 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, and 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 strip is located at one side of the opening and extends outward from the second guide rail, and forms a third limiting step with the second body, wherein the third limiting step is used to limit the glass sealing strip in the length direction of the vehicle.

[0021] It can be understood that the formed third limiting step can limit the glass sealing strip in the length direction of the vehicle, thereby preventing the window glass from being separated from the glass run channel.

[0022] In one embodiment, the second guide rail further includes a folding plate, which is located at the other side of the opening along the width direction of the vehicle and connected to the second body, and one end of the folding plate away from the second body is bent and extends into the glass run channel to form a fourth limiting step with the inner wall of the glass run channel;

[0023] The surface of the folding plate 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] It can be understood that the provided folding plate can cooperate with the third stopper bar to further limit the position of the glass sealing strip on the second guide rail, so as to improve the stability of the installation of the glass sealing strip.

[0025] In one embodiment, the first extension section and the first guide rail are integrally formed; and / or the second extension section and the second guide rail are integrally formed.

[0026] It can be understood that the integrated arrangement can reduce the connection structure between the first extension section and the first guide rail, and between the second extension section and the second guide rail, so as to make the connection between the components more stable.

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

[0028] A zero-step difference vehicle window glass guide rail system, comprising 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] Wherein, the glass sealing strip is limited in the glass guide groove through the opening, and the window glass is slidably connected to the glass sealing strip.

[0030] The present application also provides the following technical solutions:

[0031] A method for assembling a zero-order difference window glass, which is implemented based on the zero-order difference window glass guide rail system in the above embodiment. The assembling method includes the following steps:

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

[0033] Install a part of the glass sealing strip into the glass guide groove on the first guide rail.

[0034] Under the guidance of the first extension section, guide and assemble the glass bracket with the first guide rail.

[0035] Install the second guide rail on the door panel, and make the first extension section extend into the second avoidance cutout, and the second extension section extend into the first avoidance cutout.

[0039] Compared with the prior art, the zero-order difference window glass guide rail structure, system, assembling method and the vehicle thereof are provided with the first extension section, the second extension section, the first avoidance cutout and the second avoidance cutout. In this way, the first extension section can extend along the height direction of the vehicle to the outside of the outer water cut as a visual part. The visual part can play a role of prompting and guiding, so that the assembly of the window glass is no longer a blind operation. At the same time, due to the existence of the first extension section, when assembling the window glass, only need to abut the window glass against the first extension section and insert it into the glass sealing strip easily under the guidance of the first extension section, and the assembly is more convenient and efficient. At the same time, the first extension section cooperates with the second avoidance cutout, and the second extension section cooperates with the first extension section, so that the first guide rail and the second guide rail can also be accurately assembled.

[0072] Please refer to Figures 1 to 4, this application provides a zero-step window glass guide rail system 200, which includes a window glass 201, a glass sealing strip 202, a zero-step window glass guide rail structure 100, and a door panel 203. The zero-step window glass guide rail structure 100 is installed on the door panel 203, the glass sealing strip 202 is installed on the zero-step window glass guide rail structure 100, a glass bracket 2011 is provided on the window glass 201, and the glass bracket 2011 extends into the glass sealing strip 202. Among them, 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 window glass guide rail structure 100 to realize the smooth lifting of the window glass 201.

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

[0074] Not limited to this, please continue to refer to Figure 2 , the zero-step window glass guide rail system 200 further includes structures such as an inner door post trim 204 and an outer door post trim 205. In the vehicle width direction y, the inner door post trim 204 is installed on the inner side of the door post 2032 for interior decoration of the vehicle. The outer door post trim 205 covers the outer side of the door post 2032. And, in the vehicle width direction y, the outer side surface of the outer door post trim 205 is flush with the outer side surface of the window glass 201 to achieve a zero-step window.

[0075] Furthermore, as Figure 6 、 Figures 12 to 16 shown, the glass bracket 2011 includes a frame body 2012 and a limit block 2013. Along the vehicle length direction x, the frame body 2012 has a first side 2014 and a second side 2015 arranged oppositely. 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 gluing or screwing. The second side 2015 is used to extend into the glass sealing strip 202 and is slidably connected to the inside of the glass sealing strip 202. The limit block 2013 is provided on the side of the second side 2015 in the vehicle width direction y and protrudes. The limit block 2013 is used to limit and abut against the glass sealing strip 202 in the vehicle length direction x and width direction y and slidably cooperate with the inside of the glass sealing strip 202.

[0076] For the convenience of description, in this application, based on the three-dimensional coordinates of the vehicle, the vehicle length direction is defined as the x direction, the vehicle width direction is defined as the y direction, the vehicle height direction is defined as the z direction. The inside and outside of the vehicle are referenced with the vehicle cab as the object. The inside of the vehicle cab is the inside of the vehicle, and the outside of the cab is the outside of the vehicle.

[0077] As shown Figures 2 to 11 in the figure, the zero-order differential 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 relatively located below the second guide rail 20 in the vehicle height direction z. In the vehicle width direction y, both the first guide rail 10 and the second guide rail 20 have an inner side 101 and an outer side 102 arranged in opposite directions, and are both provided with a glass guide groove 103 for installing a glass sealing strip 202. The first extension section 30 is arranged at one end of the first guide rail 10 close to the second guide rail 20 and is located on the inner side 101 of the first guide rail 10. The second extension section 40 is arranged at one end of the second guide rail 20 close to the first guide rail 10 and is located on the outer side 102 of the second guide rail 20. Among them, a first avoidance notch 11 is provided on the outer side 102 of the first guide rail 10 at the end where the first extension section 30 is arranged, and a second avoidance notch 21 is provided on the inner side 101 of the second guide rail 20 at the end where the second extension section 40 is arranged. The first avoidance notch 11 is used to avoid the outer water cut and allow the second extension section 40 to extend in. The second avoidance notch 21 allows the first extension section 30 to extend in. It can be understood that in this application, by setting the first extension section 30, the second extension section 40, the first avoidance notch 11 and the second avoidance notch 21, in this way, the first extension section 30 can extend along the vehicle height direction z to the outside of the outer water cut to be used as a visualized part. The visualized part can play a role of prompting and guiding, so that the assembly of the window glass 201 is no longer a blind operation. Moreover, due to the existence of the first extension section 30, when assembling the window glass 201, only need to abut the window glass 201 against the first extension section 30 and insert it into the glass sealing strip 202 easily under the guidance of the first extension section 30, and the assembly is more convenient and efficient. At the same time, the first extension section 30 cooperates with the first avoidance notch 11, and the second extension section 40 cooperates with the second avoidance notch 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 in the body 2031, and the second guide rail 20 is installed on the door post 2032.

[0079] Here, the outer water cut of the vehicle refers to the sealing strip located between the window glass 201 and the door panel 203, and the outer part is called the outer water cut. Its main function is to scrape off the water droplets, water mist and dust on the glass surface when the window glass 201 is lifted or lowered, ensuring the clarity of the driving vision and improving the beauty of the vehicle at the same time. In addition, the glass sealing strip 202 is limited in the glass guide groove 103, and the window glass 201 is slidably connected with the glass sealing strip 202.

[0080] Further, please refer to Figure 9 and Figure 10, the first avoidance notch 11 includes a first notch 111 and a second notch 112 that are interconnected, and the second avoidance notch 21 includes a third notch 211 and a fourth notch 212 that are interconnected; wherein, the first notch 111 and the third notch 211 are oppositely arranged in the vehicle width direction y, and the second notch 112 and the fourth notch 212 are correspondingly arranged in the vehicle length direction x and form an avoidance notch 104.

[0081] It should be noted 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 assembly surface in the vehicle width direction). Therefore, there is generally no misalignment or the error is within the allowable range in the vehicle width direction y of the docking area between the first guide rail 10 and the second guide rail 20. However, due to the assembly error, there may be misalignment in the vehicle length direction x of the docking area between the first guide rail 10 and the second guide rail 20. At this time, when the window glass 201 is lifted and lowered, when the glass bracket 2011 moves to the docking area of the two guide rails, that is, when it moves to the connection transition area between the first guide rail 10 and the second guide rail 20, the limit block 2013 will swing in the vehicle front-rear direction due to different forces caused by this misalignment. At this time, the window glass 201 is relatively easy to tilt in the vehicle height direction z and get stuck, affecting the user experience. In this application, through the avoidance notch 104 formed by the second notch 112 and the fourth notch 212 in the vehicle length direction x, a hollow is formed on one side in the vehicle length direction x of the connection transition area between the first guide rail 10 and the second guide rail 20. In this position, only the glass seal strip 202 exists. When the glass bracket 2011 moves to this connection transition area, the avoidance notch 104 is used to release the limit of the glass bracket 2011 in the length direction x, so as to reduce the abutment limit on the glass bracket 2011, thereby compensating for the assembly error between the two in the vehicle length direction x, so that the glass bracket 2011 can smoothly pass through the connection transition area between the first guide rail 10 and the second guide rail 20, and avoid the phenomenon of jamming when the window glass 201 is lifted and lowered.

[0082] Specifically, as Figure 5 and Figure 6 shown, both the first guide rail 10 and the second guide rail 20 have openings 105 in the vehicle length direction x, and the openings 105 communicate with the glass guide grooves 103. In the vehicle length direction x, the vehicle has a front end and a rear end, the openings 105 are arranged towards the front end, and a part of the glass seal strip 202 is installed in the glass guide groove 103 through the openings 105. The first notch 111 is located on the inner side 101 of the vehicle, the third notch 211 is located on the outer side 102 of the vehicle, and the second notch 112 and the fourth notch 212 are arranged towards the rear end of the vehicle.

[0083] As Figure 5As shown in the figure, the first guide rail 10 includes a first main body 12 and a first stop strip 13. The above-mentioned glass guide groove 103 is formed on the first main body 12. Along the vehicle width direction y, the first stop strip 13 is located on one side of the opening 105 and extends towards the outer side 102 of the first guide rail 10, and a first limiting step 14 is formed between the first stop strip 13 and the first main body 12. The first limiting step 14 is used to abut and limit the glass sealing strip 202 in the vehicle length direction x, so as to prevent the glass sealing strip 202 from detaching from the opening 105. The limiting block 2013 abuts against the glass sealing strip 202 at the position with the first limiting step 14, which is equivalent to also abutting against the first limiting step 14 at this position.

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

[0085] Further, please continue to refer to Figure 5 , the first guide rail 10 further includes a second stop strip 15. The second stop strip 15 is located on the other side of the opening 105 and is connected to the first main body 12, and the second stop strip 15 is recessed relative to the first main body 12 towards the inside of the glass guide groove 103 to form a first limiting surface 151 for abutting and limiting the glass sealing strip 202 in the vehicle width direction y; and, a second limiting step 152 for limiting the glass sealing strip 202 in the vehicle length direction x is formed between the second stop strip 15 and the first main body 12. In this way, the second limiting step 152 can cooperate with the second stop strip 15 to limit the glass sealing strip 202 in both the vehicle length direction x and the vehicle width direction y, so as to further ensure the installation stability of the glass sealing strip 202.

[0086] It should be explained that the glass sealing strip 202 is installed in the glass guide groove 103, and it mainly plays a sealing role. The outer contour of the part of the glass sealing strip 202 installed in the glass guide groove 103 basically matches the inner contour of the glass guide groove 103. The limiting block 2013 is in the glass guide groove 103. At this time, in the x direction of the vehicle, the limiting block 2013 is also equivalent to abutting and limiting against the first limiting step 14. In the y direction of the vehicle, the limiting block 2013 is also equivalent to limiting and abutting against the first limiting surface 151. At the same time, the limiting block 2013 will also abut against other groove walls in the glass guide groove 103, so as to realize the limiting of the limiting block 2013 inside the glass guide groove 103 (in the vehicle length direction x and the vehicle width direction y).

[0087] Further, as shown in Figure 5As shown, in the longitudinal direction x of the vehicle, the second stop bar 15 is provided with an extension section 153 at one end away from the first body 12, and the extension section 153 is bent relative to the second stop bar 15 toward the outer side of the first guide rail 10 to form a blocking portion 154, and the blocking portion 154 is used to limit the position against the glass sealing strip 202 in the longitudinal direction x of the vehicle. In this way, the glass sealing strip 202 is further limited.

[0088] See also Figure 6 The second guide rail 20 includes a second body 22 and a third stopper 23. The second body 22 is also provided with the above-mentioned glass run groove 103 and an opening 105. Along the vehicle width direction y, the third stopper 23 is located on one side of the opening 105 and extends to the outside of the second guide rail 20, and forms a third limiting step 24 between the third stopper 23 and the second body 22. The third limiting step 24 is used to limit the glass sealing strip 202 in the length direction x of the vehicle. In this way, the formed third limiting step 24 can make the glass sealing strip 202 be abutted and limited in the length direction x of the vehicle, thereby preventing the window glass 201 from being separated from the glass run 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 run groove 103 on the second body 22, at this time, in the length direction x of the vehicle, the limiting block 2013 is also equivalent to being abutted and limited with the third limiting step 24. Moreover, in the longitudinal direction x of the vehicle, the groove wall in the glass guide groove 103 away from the opening 105 also forms a limiting abutment with the limiting block 2013, so that the limiting block 2013 is limited forward and backward in the longitudinal direction x of the vehicle in 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 further includes a folding plate 25, which is located at the other side of the opening 105 and connected to the second body 22 along the vehicle width direction y. The folding plate 25 is bent at one end away from the second body 22 and extends into the glass run groove 103 to form a fourth limiting step 26 between the inner wall of the glass run groove 103. The surface of the folding plate 25 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. In this way, the folding plate 25 can cooperate with the third stop bar 23 to further limit the glass sealing strip 202 on the second guide rail 20, so as to improve the stability of the installation of the glass sealing strip 202.

[0091] Further, in the vehicle width direction y, a convex portion 2016 is provided on a side surface of the second side 2015 of the frame body 2012 facing away from the limiting block 2013, and the convex portion 2016 abuts and limits against the surface of the folding plate 25 in the vehicle width direction y; and in the vehicle width direction y, a side surface of the limiting block 2013 facing away from the frame body 2012 abuts and limits against the inner wall of the glass guide groove 103. In this way, within the second guide rail 20, the position limit of the frame body 2012 in the vehicle width direction y is achieved through the convex portion 2016 and the limiting block 2013 to prevent it from shaking.

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

[0093] Please continue to refer to Figure 4 and Figure 5 , the first extension section 30 and the first guide rail 10 are provided integrally; and / or, the second extension section 40 and the second guide rail 20 are provided integrally. It can be understood that the integral setting method 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 difference 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, and the second extension section 40 and the second guide rail 20 can be integrally formed by rolling or extrusion.

[0095] In an embodiment, please refer to Figure 6 and Figures 12 to 16 , these figures more specifically illustrate the installation relationship between the window glass 201 and the glass bracket 2011, and the specific structure of the limiting block 2013.

[0096] Specifically, the stop block 2013 includes a first hard block 441 and a first elastic block 442. The first hard block 441 is disposed on the side of the second side 2015 in the width direction y of the vehicle and is protruding. The first hard block 441 abuts against a wall of the glass run channel 103 in the width direction y of the vehicle for position limiting. A hard stop step 443 is formed between the first hard block 441 and the frame 2012 on one side in the length direction x of the vehicle. The hard stop step 443 abuts against the glass sealing strip 202 in the length direction x of the vehicle, that is, abuts against the first stop step 14 or the third stop step 24 for position limiting. The first elastic block 442 is disposed on the other side of the first hard block 441 in the length direction x of the vehicle and is protruding. The first elastic block 442 abuts against the wall of the glass run channel 103 in the width direction y of the vehicle and away from the opening 105 for position limiting. That is, the hard limit step 443 and the first elastic block 442 are both matched with the corresponding structural limit. It should be explained that the second side 2015 is limited in the length direction x of the vehicle by setting the first elastic block 442 and forming the hard limit step 443, and using the hard limit step 443 and the first elastic block 442. Since the first elastic block 442 has elastic deformation ability, it can provide a certain deformable space in the length direction of the vehicle, thereby providing support and structural release space for the space deformation and the movement to one side caused by the size or lifting and flipping external force of the limit environment, and effectively avoiding the occurrence of the window glass jamming phenomenon.

[0097] At the same time, combined with the setting of the avoidance slot 104, as the window glass 201 rises and falls, when the limit block 2013 moves to the connection transition area between 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 Figures 12 to 15 , the first elastic block 442 is set to be arc-shaped, and a hollow groove 444 is formed between the arc-shaped first elastic block 442 and the first hard block 441. It can be understood that the arc-shaped first elastic block 442 can reduce the contact area between it and the glass sealing strip 202, thereby reducing the friction resistance between the two, so as to ensure the smoothness of the lifting and lowering of the vehicle window glass 201, and the arc-shaped first elastic block 442 has good buffering ability, so that the limit block 2013 can absorb and disperse a part of the external force through its own deformation; at the same time, the setting of the hollow groove 444 makes the first elastic block 442 have higher flexibility, so that the first elastic block 442 has better deformable space when it is subjected to external force, and combined with the support and limit function of the first hard block 441, it can make the glass bracket 2011 play its own supporting role while having better tolerance.

[0099] Furthermore, ifFigure 16 and Figure 17 As shown in Figure 17 , the first elastic block 442 includes an arc segment 4421 and a straight segment 4422. One end of the arc 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 end of the arc segment 4421 that is suspended relative to the first rigid block 441 and encloses 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 direction x of the vehicle. Here, the arc segment 4421 has a relatively long elastic deformation ability, so that the applicable space of the first elastic block 442 is relatively large. 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 support of the glass bracket 2011 for the window glass 201 and making the movement of the window glass 201 smoother.

[0100] In one embodiment, as Figure 17 shown in Figure 17 , the length of the straight segment 4422 is L, and L≥2mm. Here, the length of the straight segment 4422 should not be too small. A relatively long straight segment 4422 can enable the first elastic block 442 to have a sufficient contact area with the first elastic block 442, thereby improving the stability of the support of the glass bracket 2011 for the window glass 201.

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

[0102] In one embodiment, the arc segment 4421 and the first rigid block 441 are smoothly connected by an arc chamfer 4423. Here, the arc chamfer 4423 has a buffering effect. By smoothly connecting the first rigid block 441 and the arc segment 4421 through the arc chamfer 4423, a part of the force can be absorbed and dispersed when the first elastic block 442 is suddenly stressed, improving the reliability of the connection between the first elastic block 442 and the first rigid block 441 and avoiding damage to the connection structure due to stress.

[0103] Preferably, as Figure 15 shown in Figure 15 , the radius of the arc chamfer 4423 is R, and R≥1mm.

[0104] Here, the value of the radius R of the arc chamfer can be 1mm, 1.5mm, 2mm, etc. The specific value of the radius R of the arc chamfer can be determined according to the actual situation and is not limited here. In this embodiment, the radius R of the arc chamfer is set to 1mm.

[0105] In one embodiment, 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 of the two arc segments 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 FIG. 16. Along the length direction x of the vehicle, the maximum height of the hollow groove 444 is H, that is, the distance between the straight segment 4422 and the first rigid block is H, and H≥2 mm. In this way, the buffer path of the first elastic block 442 is small and its optimal buffer capacity cannot be exerted, that is, it is ensured that the first elastic block 442 can exert its deformation buffer capacity to the maximum extent.

[0107] Here, the value of the maximum height H of the hollow groove 444 can be 2 mm, 2.3 mm, 2.6 mm, 3 mm, 3.5 mm, 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 herein. In this embodiment, the maximum height H of the hollow groove 444 is set to 2 mm.

[0108] As Figure 18 shown, the present application also provides a zero-order difference window glass assembly method, which is implemented based on the zero-order difference window glass guide system 200 in the above embodiment. Specifically, the assembly method includes the following steps:

[0109] Step S100, install the first guide rail 10 on the door panel 203, and through the avoidance of the first avoidance notch 11, make the first extension segment 30 protrude from the outer water cut on the door panel 203 in the height direction z of the vehicle, so that the first extension segment 30 is externally exposed;

[0110] Step S200, install a part of the glass sealing strip 202 into the glass guide groove 103 on the first guide rail 10;

[0111] Step S300, under the guidance of the first extension segment 30, guide and assemble the glass bracket 2011 with the first guide rail 10;

[0112] Step S400, install the second guide rail 20 on the door panel 203, and make the first extension segment 30 extend into the second avoidance notch 21, and the second extension segment 40 extend into the first avoidance notch 11;

[0113] Step S500, install the other part of the glass sealing strip 202 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 identify and prompt the assembly, but also guide the installation of the glass bracket 2011 by using the first extension section 30, so that the window glass 201 can be assembled smoothly and quickly, greatly improving the assembly efficiency.

[0115] It should be understood that unless there is a clear description in this article, there is no strict order restriction on the operations of the above steps. These steps can be operated sequentially or in other orders, and the specific operation steps can be determined according to the actual situation.

[0116] The present application also provides a vehicle, including the zero-order difference window glass guide rail system 200 as described in the above embodiment.

[0117] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, 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, it should be considered as the scope described in this specification.

[0118] The above-described embodiments only express several implementation manners of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
