[0045] To make the objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0046] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on the other component or there may be an intermediate component.

Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0048] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature and the second feature are in indirect contact through an intermediate medium.

[0049] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.
[0050] Currently, zero-step differential side door windows mainly consist of glass, glass brackets, guide rails, door pillars, and exterior trim panels. The guide rails are fixed to the door pillars, one side of the glass bracket is mounted on the glass, and the other side slides along the guide rail. The exterior trim panel is assembled onto the door pillar and, together with the glass bracket, forms a groove for limiting the glass sealing strip. In other words, the exterior trim panel typically participates in limiting the glass sealing strip along the vehicle's length or width. This adds some difficulty to the assembly of the exterior trim panel, and the stress on the exterior trim panel also affects the surface difference between it and the glass.
[0051] Furthermore, the zero-step window glass bracket is installed on the window glass and connected to the glass guide rail to achieve a zero-step appearance between the window glass and the door pillar exterior trim panel, and to provide stable guidance and support for the window glass, allowing it to move smoothly during raising and lowering. However, the height of the window glass on both sides of the vehicle's length is generally not equal. Therefore, during its raising and lowering, the forces acting on the two sides of the window glass will also be significantly different. This may cause the window glass to rotate around the locking point, resulting in the window glass jamming and affecting the user experience.
[0052] In view of this, embodiments of this application provide a zero-level difference vehicle door side window system, a zero-level difference vehicle window glass guide rail system, a zero-level difference vehicle window glass bracket, and a vehicle, which are easy to assemble, have good consistency, and stable zero-level surface difference.
[0053] Please refer to Figure 1. This application provides a vehicle including a zero-step differential door side window system 100. Here, 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 referenced to the vehicle's passenger compartment; the interior of the passenger compartment is the inner side of the vehicle, and the exterior of the passenger compartment is the outer side of the vehicle.
[0054] Referring to Figure 2, the zero-step differential door side window system 100 includes a door 10, glass 20, a guide rail unit 30, a glass bracket 40, and a door pillar exterior panel 50. The guide rail unit 30 is mounted on the door 10, and the glass bracket 40 is mounted on the glass 20. The glass bracket 40 and the guide rail unit 30 are slidably connected, allowing the glass 20 to rise and fall relative to the guide rail unit 30 in the z-direction. The door pillar exterior panel 50 is located on the outside of the vehicle and mounted on the door 10 for decorative purposes. Furthermore, in the y-direction of the vehicle, the outer surface of the glass 20 is flush with the outer surface of the door pillar exterior panel 50 to achieve a zero-step difference between them.
[0055] Of course, the embodiments of this application are not limited to this. The zero-step differential door side window system 100 also includes structures such as door pillar interior panel 60. The door pillar interior panel 60 is located on the inside of the vehicle and installed on the door 10 to serve a decorative purpose.
[0056] Please refer to Figures 2 and 3. The door 10 includes a door body 11 and a door pillar 12. In the height direction z of the vehicle, the door pillar 12 is located above the door body 11. The guide rail unit 30 has a guide groove 31. An opening 32 communicating with the guide groove 31 is provided on one side of the guide groove 31 in the length direction x of the vehicle. Furthermore, an x-direction limiting structure 311 is provided inside the guide groove 31 in the length direction x of the vehicle and a y-direction limiting structure 312 is provided in the width direction y of the vehicle. The glass bracket 40 has a first side portion 41 and a second side portion 42 in the vehicle's length direction x. The first side portion 41 is connected to the glass 20, and the second side portion 42 extends into the guide groove 31 through the opening 32. In the vehicle's length direction x, the second side portion 42 is limited and abuts against the x-direction limiting structure 311, and in the vehicle's width direction y, the second side portion 42 is limited and abuts against the y-direction limiting structure 312. That is, the guide groove 31 effectively limits the glass bracket 40 in both the vehicle's length direction x and width direction y. The door pillar exterior panel 50 is installed on the outer surface of the door pillar 12 in the vehicle's width direction y and overlaps with the guide rail unit 30 in the vehicle's width direction y. The outer surface of the door pillar exterior panel 50 in the vehicle's width direction y is flush with the outer surface of the glass 20 in the vehicle's width direction y. Therefore, this application sets an x-direction limiting structure 311 and a y-direction limiting structure 312 in the guide groove 31, and limits the second side 42 in the vehicle length direction x and width direction y through the corresponding x-direction limiting structure 311 and y-direction limiting structure 312, respectively. At this time, the door pillar outer trim panel 50 overlaps with the guide rail unit 30, thereby decoupling the functional components related to the limiting and lifting of the glass 20 from the decorative components. In this way, the door pillar outer trim panel 50 only serves a decorative function and no longer needs to cooperate with the guide rail to limit the glass bracket 40. Therefore, it only needs to be installed on the door pillar 12, which greatly reduces the installation difficulty of the door pillar outer trim panel 50 and improves the consistency of assembly. At the same time, since the door pillar outer trim panel 50 no longer participates in the limiting, the error caused by assembly is reduced. That is, the assembly error of the door pillar outer trim panel 50 will not affect the fitting accuracy between the glass bracket 40 and the guide rail, which is conducive to improving the stability of the glass bracket 40.
[0057] In this embodiment, the door body 11 is a sheet metal part, and the door pillar 12 and the door body 11 can be integrally formed to improve the overall structural strength of the door.
[0058] Please refer to Figure 3. The guide rail unit 30 includes a guide rail 33 and a glass sealing strip 34. A guide groove 31 and an opening 32 are both formed in the guide rail 33. A portion of the glass sealing strip 34 is installed within the guide groove 31 through the opening 32 and is limited by an x-direction limiting structure 311 and a y-direction limiting structure 312. The second side portion 42 extends into the glass sealing strip 34 and is slidably connected to it. The glass sealing strip 34 is used to seal against the glass 20, thereby isolating the inner and outer sides of the vehicle.
[0059] It should be explained that the glass sealing strip 34 primarily serves a sealing function, and the outer contour of the portion that mates with the guide groove 31 basically matches the contour of the guide groove 31. The second side portion 42 extends into the glass sealing strip 34, and in the vehicle's length direction (x) and width direction (y), it indirectly restrains and abuts against the x-direction limiting structure 311 and the y-direction limiting structure 312 respectively through the glass sealing strip 34. Of course, the x-direction limiting structure 311 and the y-direction limiting structure 312 also limit the glass sealing strip 34, thereby preventing the glass sealing strip 34 from coming out of the opening 32.
[0060] In one embodiment, the x-direction limiting structure 311 includes a first limiting portion 3111 and a second limiting portion 3112, which are spaced apart in the vehicle's length direction x, forming a first limiting space 3113; the second side portion 42 is limited within the first limiting space 3113 in the vehicle's length direction x. That is, in the longitudinal direction of the vehicle's length direction x, the second side portion 42 is limited within the first limiting space 3113.
[0061] Specifically, the guide rail 33 includes a guide rail body 331 and a stop bar 332. The guide rail body 331 has the aforementioned guide groove 31 and the aforementioned opening 32. In the vehicle's length direction x, the groove wall of the guide groove 31 away from the opening 32 forms a first limiting portion 3111. In the vehicle's width direction y, the stop bar 332 is located on one side of the opening 32 and is connected to the guide rail body 331, extending outward from the vehicle, so that a second limiting portion 3112 is formed between the stop bar 332 and the guide rail body 331. When the second side portion 42 is located in the guide groove 31, in the vehicle's length direction x, the second side portion 42 can be limited by the stop bar 332 and the guide rail body 331, so that the second side portion 42 does not wobble in the vehicle's length direction x.
[0062] Here, the first limiting part 3111 and the second limiting part 3112 can be one of a plane, a stepped surface, a groove, a protrusion, etc.
[0063] As shown in Figure 4, the y-direction limiting structure 312 includes a third limiting part 3121 and a fourth limiting part 3122. The third limiting part 3121 and the fourth limiting part 3122 are spaced apart in the width direction y of the vehicle, forming a second limiting space 3123. The second side part 42 is limited within the second limiting space 3123 in the width direction y of the vehicle. In this way, the second side part 42 is limited in the width direction y of the vehicle by the third limiting part 3121 and the fourth limiting part 3122, so as to prevent the glass bracket 40 from swaying left and right in the width direction y of the vehicle.
[0064] Specifically, the guide rail 33 also includes a folded plate 333. In the width direction y of the vehicle, one of the groove walls of the guide groove 31 forms a third limiting part 3121, and the folded plate 333 is located on the other groove wall of the guide groove 31 in the width direction y of the vehicle, forming a fourth limiting part 3122. Thus, when the second side part 42 is located in the guide groove 31, it is limited in the left and right directions of the width direction y of the vehicle by the third limiting part 3121 and the fourth limiting part 3122, respectively.
[0065] In this embodiment of the application, the folding plate 333 is located outside the guide rail 33 in the width direction y of the vehicle.
[0066] Here, the third limiting part 3121 and the fourth limiting part 3122 can be one of a plane, a stepped surface, a groove, a protrusion, etc.
[0067] Furthermore, one end of the folding plate 333 is connected to the guide rail body 331, and the other end is bent relative to the guide rail body 331 and extends into the guide groove 31, forming a limiting groove 3331 with the groove wall of the guide groove 31. In combination with the baffle 332, the glass sealing strip 34 is limited in front and behind in the vehicle length direction x by the limiting groove 3331 and the second limiting part 3112, thereby preventing the glass sealing strip 34 from coming out of the opening 32.
[0068] In this embodiment, referring to Figure 4, the guide rail body 331 has a "C" or "U" shaped cross-section in the vehicle width direction y, that is, the cross-section of the guide rail body 331 is "C" or "U" shaped. The second side portion 42 is located inside the "C" or "U" shape, that is, in this application, the limiting of the second side portion 42 is completed inside the guide rail body 331.
[0069] In one embodiment, the guide rail 33 is integrally formed by roll forming or extrusion. That is, the guide rail body 331, the stop bar 332, and the folding plate 333 are set as an integral structure, which can effectively improve the structural strength of the guide rail 33.
[0070] As shown in Figures 5 to 7, along the length x of the vehicle, a first mounting point 334 is provided on one side of the guide rail 33, and a second mounting point 335 is provided on the other side of the guide rail 33. Both the first mounting point 334 and the second mounting point 335 are connected to the door post 12. In this way, the guide rail 33 can be stably fixed to the door post 12 through the mounting points arranged on both sides of the guide rail 33.
[0071] In one embodiment, the connection between the first mounting point 334 and the guide rail 33 is configured as any one or a combination of threaded connection, welding, and riveting; the connection between the second mounting point 335 and the guide rail 33 is configured as welding or threaded connection.
[0072] In one embodiment of this application, the first mounting point 334 is connected to the guide rail 33 by a thread, and the second mounting point 335 is also connected to the guide rail 33 by a thread.
[0073] Please refer to Figure 6. A first bolt 3341 is provided at the first mounting point 334 of the guide rail 33. A through hole 121 is provided at the corresponding position of the doorpost 12. The first bolt 3341 passes through the through hole 121 and is locked in place with a nut. Here, the first bolt 3341 at the first mounting point 334 is first fixed to the guide rail 33 by welding, and then during installation, the first bolt 3341 is aligned and passes through the through hole 121.
[0074] As shown in Figure 7, a second bolt 3351 is provided at the second mounting point 335 of the guide rail 33. Similarly, a connecting hole (not marked in the figure) is provided on both the door post 12 and the guide rail 33. One end of the second bolt 3351 passes through the connecting hole and is then connected to the nut, thereby realizing the installation of the guide rail 33 at this position.
[0075] Please refer to Figures 3 and 8 to 13. The glass bracket 40 includes a frame 43 and a limiting member 44. The frame 43 has a first side portion 41 and a second side portion 42 arranged opposite to each other in the vehicle's length direction x. The first side portion 41 is mounted on the glass 20, and the second side portion 42 extends into the glass sealing strip 34 and is slidably connected to the inside of the glass sealing strip 34. The limiting member 44 includes a first rigid block 441 and a first elastic block 442. The first rigid block 441 is disposed on the side of the second side portion 42 in the vehicle's width direction y and protrudes outward. The first rigid block 441 engages with the y-direction limiting structure 312 in the vehicle's width direction y. A rigid limiting step 443 is formed between the first rigid block 441 and the frame 43 on one side in the vehicle's length direction x. The rigid limiting step 443 rigidly abuts against the glass sealing strip 34 in the vehicle's length direction x, that is, it abuts against the second limiting portion 3112. The first elastic block 442 is disposed on the other side of the first rigid block 441 in the vehicle length direction x and protrudes outward. The first elastic block 442 and the first limiting part 3111 are elastically and limitingly abut against each other. That is, both the rigid limiting step 443 and the first elastic block 442 are limited and cooperate with the x-direction limiting structure 311.
[0076] It should be explained that by setting the first elastic block 442 and forming the rigid limiting step 443, the second side 42 is limited in the x-direction of the vehicle's length by utilizing 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. This provides support and structural release space for spatial deformation and glass tilting caused by the size of the glass or the external force generated during glass lifting and lowering, effectively preventing the window glass from jamming and thus improving the smoothness of window glass lifting and lowering.
[0077] In this embodiment, along the length x of the vehicle, a rigid limiting step 443 is provided on the side of the limiting member 44 facing the opening 32, and a first elastic block 442 is provided on the side of the limiting member 44 away from the opening 32.
[0078] In one embodiment, a second elastic block (not shown) is provided on one of the sides of the frame 43 away from the first rigid block 441 and the side of the first rigid block 441 away from the frame 43 along the width direction y of the vehicle. The second elastic block is used to elastically abut against the glass sealing strip 34 in the width direction y of the vehicle. In this way, the glass sealing strip 34 can be abutted and limited in the width direction y of the vehicle, and the elastic deformation capability of the second elastic block can be used to give the glass bracket 40 space for elastic deformation in the width direction y of the vehicle. At the same time, in combination with the provision of the first elastic block 442, the tolerance of the glass bracket 40 is further increased, so that the glass bracket 40 can effectively avoid jamming in both the length direction x and the width direction y of the vehicle.
[0079] Furthermore, as shown in Figures 12 and 13, a second rigid block 444 is provided on one of the sides of the frame 43 away from the first rigid block 441 and the other side of the first rigid block 441 away from the frame 43, along the width direction y of the vehicle. Thus, an elastic abutment and a rigid abutment are formed in the width direction y of the vehicle. The elastic abutment improves tolerance, while the rigid abutment improves limiting stability. Here, the positions of the second rigid block 444 and the second elastic block can be interchanged, and their specific positions can be determined according to actual conditions.
[0080] In another embodiment, along the width direction y of the vehicle, a second rigid block 444 is provided on the side of the frame 43 away from the first rigid block 441 and the side of the first rigid block 441 away from the frame 43. The second rigid block 444 is used to abut against the glass sealing strip 34 in the width direction y of the vehicle, so that the glass 20 can have a certain supporting force in the width direction y of the vehicle and be further limited and fixed.
[0081] In this embodiment, the second rigid block 444 is configured in an arc shape so that while supporting and limiting the glass sealing strip 34, the contact area between the second rigid block 444 and the glass sealing strip 34 is reduced, thereby reducing the frictional resistance when the glass 20 moves.
[0082] Please refer to Figures 11 to 13. The first elastic block 442 is arc-shaped, and a hollow groove 445 is formed between the arc-shaped first elastic block 442 and the first rigid block 441. It can be understood that setting the first elastic block 442 to be arc-shaped can reduce the contact area between it and the glass sealing strip 34, thereby reducing the frictional resistance between the two to ensure the smoothness of the glass 20's lifting and lowering. The arc-shaped first elastic block 442 also has good buffering capacity, allowing the limiting member 44 to absorb and disperse part of the external force through its own deformation when subjected to external force. At the same time, the hollow groove 445 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 supporting and limiting function of the first rigid block 441, the glass bracket 40 can play its supporting role while having good tolerance.
[0083] Further, as shown in Figure 13, 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 other end of the arc-shaped segment 4421 that is suspended relative to the first rigid block 441, and together with the first rigid block 441, they form a hollow groove 445, which is used to elastically limit the movement of the vehicle in the x-direction and abut against the glass sealing strip 34. Here, the arc-shaped segment 4421 has a larger 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 34, thereby increasing the stability of the glass bracket 40 supporting the glass 20 and making the movement of the glass 20 more stable.
[0084] In one embodiment, as shown in FIG14, 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 allows the first elastic block 442 and the glass sealing strip 34 to have sufficient contact area, thereby improving the stability of the glass bracket 40 supporting the glass 20.
[0085] Specifically, the length L of the straight segment 4422 can be 2mm, 3mm, 5mm, or other values. 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 one embodiment of this application, the length L of the straight segment 4422 is set to 2mm. In addition, the upper limit of the length L of the straight segment 4422 can be determined according to the actual size of the window, glass bracket, limiting member, or first elastic block, and is not limited here. For example, in some embodiments, the upper limit of the length L of the straight segment 4422 can be 20mm.
[0086] 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.
[0087] In this embodiment of the application, as shown in Figure 14, the radius of the arc chamfer 4423 is R, where R ≥ 1 mm.
[0088] 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 one embodiment of this application, the radius R of the curved chamfer is set to 1mm. Furthermore, the upper limit of the radius R of the curved chamfer 4423 can be determined according to the actual structural dimensions of the window, glass bracket, limiting member, or first elastic block, etc., without limitation. For example, in some embodiments, the upper limit of the radius R of the curved chamfer 4423 can be 10mm.
[0089] In one embodiment, as shown in Figures 13 and 14, 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.
[0090] Referring to Figure 14, along the length x of the vehicle, the maximum height of the hollow groove 445 is H, which is also the distance between the straight segment 4422 and the first rigid block, where H ≥ 2mm. When H is less than 2mm, the buffering path of the first elastic block 442 is too small, preventing it from achieving its optimal buffering capacity. When H is set to be greater than or equal to 2mm, it ensures that the first elastic block 442 can maximize its deformation buffering capacity.
[0091] Here, the maximum height H of the hollow groove 445 can be 2mm, 2.3mm, 2.6mm, 3mm, 3.5mm, etc., and the specific value of the maximum height H of the hollow groove 445 can be determined according to the actual situation, and is not limited here. In this embodiment, the maximum height H of the hollow groove 445 is set to 2mm. In addition, the upper limit of the maximum height H of the hollow groove 445 can be determined according to the actual structural dimensions of the window, glass bracket, limiting member, or first elastic block, etc., and is not limited here. For example, in some embodiments, the upper limit of the maximum height H of the hollow groove 445 can be 20mm.
[0092] In one embodiment, the doorpost exterior panel 50 is connected to the doorpost 12 by one or more of the following methods: hook connection, snap connection, adhesive connection, and threaded connection. In this embodiment, the doorpost exterior panel 50 and the doorpost 12 are simultaneously fixed by both hook connection and threaded connection.
[0093] As shown in Figures 5 and 15, the doorpost 12 has a hanging hole 122, and a hook 51 is provided on the side of the doorpost outer panel 50 facing the doorpost 12. The hook 51 can be hooked into the hanging hole 122 to connect the doorpost outer panel 50 to the doorpost 12. Simultaneously, a nut is embedded in the doorpost outer panel 50, and a through hole corresponding to the nut is provided on the doorpost 12. A threaded component is then passed through this through hole and connected to the nut. Here, the threaded component can be a bolt or a screw.
[0094] Furthermore, the door pillar exterior panel 50 can also be provided with adhesive. After the door pillar exterior panel 50 is connected by hooks and threaded parts, it is also glued to the side of the guide rail 33 in the vehicle width direction by adhesive, thereby realizing the three-fold fixation of the door pillar exterior panel 50 and further improving its installation stability.
[0095] The zero-step differential window glass guide rail system 200 according to an embodiment of the present application will now be described with reference to Figures 16 to 20.
[0096] Referring to Figure 16, this application provides a zero-step differential window glass guide rail system 200. The system includes a window glass (or glass) 20, a zero-step differential window glass guide rail structure 400, a glass sealing strip 34, and a zero-step differential window glass bracket 300. The glass sealing strip 34 is installed within the zero-step differential window glass guide rail structure 400, and the zero-step differential window glass bracket 300 is installed on the window glass 20 and slidably and limit-connected with the glass sealing strip 34, providing stable guidance and support for the window glass 20. This allows the window glass 20 to move smoothly along a preset trajectory during lifting and lowering, avoiding shaking or jamming.
[0097] Meanwhile, the glass sealing strip 34 is generally attached to the inner wall of the zero-step differential window glass guide structure 400, and its outer contour is basically the same as the inner contour of the zero-step differential window glass guide structure 400. The zero-step differential window glass bracket 300 and the glass sealing strip 34 are matched for limiting, which is equivalent to matching the zero-step differential window glass guide structure 400. The only difference is that the glass sealing strip 34 is set between the zero-step differential window glass bracket 300 and the zero-step differential window glass guide structure 400 for sealing.
[0098] As shown in Figures 17 to 19, the zero-step differential window glass bracket 300 includes a frame 43 and a limiting member 44. In the vehicle's longitudinal direction x, the frame 43 has a first side 41 and a second side 42 disposed opposite to each other. The first side 41 is used to mount the window glass 20, and the second side 42 is used to extend into the glass sealing strip 34 and slide within it. The limiting member 44 includes a first rigid block 441 and a first elastic block 442. The first rigid block 441 is disposed on the second side 41. 2. A rigid block 441 is provided on the side of the vehicle in the width direction (y) and protrudes outwards. A rigid limiting step 443 is formed between the first rigid block 441 on one side of the vehicle in the length direction (x) and the frame 43. The rigid limiting step 443 is used to rigidly abut against the glass sealing strip 34 in the length direction (x). A first elastic block 442 is provided on the other side of the first rigid block 441 in the length direction (x) and protrudes outwards. The first elastic block 442 is used to elastically limit and abut against the glass sealing strip 34 in the length direction (x). It should be explained that this application achieves the limitation of the frame 43 in the length direction (x) by providing a rigid limiting step 443 and a first elastic block 442 on two sides of the vehicle in the length direction (x), respectively abutting against the glass sealing strip 34. Simultaneously, the elasticity of the first elastic block 442 provides a certain deformable space, effectively preventing the window glass 20 from jamming, thereby improving the smoothness of the window glass 20's raising and lowering.
[0099] In one embodiment, a second elastic block (not shown) is provided on one of the sides of the frame 43 away from the first rigid block 441 and the side of the first rigid block 441 away from the frame 43 along the width direction y of the vehicle. The second elastic block is used to elastically abut against the glass sealing strip 34 in the width direction y of the vehicle. In this way, the glass sealing strip 34 can be abutted and limited in the width direction y of the vehicle, and the elastic deformation capability of the second elastic block can be used to allow the zero-step differential window glass bracket 300 to have space for elastic deformation in the width direction y of the vehicle. At the same time, combined with the provision of the first elastic block 442, the zero-step differential window glass bracket 300 can effectively avoid jamming in both the length direction x and the width direction y of the vehicle, further increasing the tolerance of the zero-step differential window glass bracket 300.
[0100] Furthermore, along the width direction y of the vehicle, a second rigid block 444 is provided on the other of the side of the frame 43 away from the first rigid block 441 and the side of the first rigid block 441 away from the frame 43. Thus, in the width direction y of the vehicle, an elastic abutment and a rigid abutment are formed. The elastic abutment can improve tolerance, and the rigid abutment can improve limiting stability.
[0101] Here, the positions of the second rigid block 444 and the second elastic block can be interchanged, and their specific positions can be determined according to the actual situation.
[0102] In another embodiment, along the width direction y of the vehicle, a second rigid block 444 is provided on the side of the frame 43 away from the first rigid block 441 and the side of the first rigid block 441 away from the frame 43. The second rigid block 444 is used to abut against the glass sealing strip 34 in the width direction y of the vehicle, so that the window glass 20 can have a certain supporting force in the width direction y of the vehicle and be further limited and fixed.
[0103] In this embodiment, both the second rigid block 444 and the second elastic block can be set to an arc shape so that while supporting and limiting the glass sealing strip 34, they can reduce the contact area between themselves and the glass sealing strip 34, thereby reducing the frictional resistance when the window glass 20 moves.
[0104] In one specific embodiment, in the vehicle length direction x, a rigid limiting step 443 is formed between the side of the first rigid block 441 facing the window glass 20 and the frame 43, and the first elastic block 442 is located on the side of the first rigid block 441 away from the frame 43.
[0105] Furthermore, in the width direction x of the vehicle, the end of the first rigid block 441 away from the second side 42 is limited and engaged with one side of the glass sealing strip 34, and the second rigid block 444 is limited and engaged with the other side of the glass sealing strip 34.
[0106] Please refer to Figures 18 to 20. The first elastic block 442 is arc-shaped, and a hollow groove 445 is formed between the arc-shaped first elastic block 442 and the first rigid block 441. It can be understood that setting the first elastic block 442 to be arc-shaped can reduce the contact area between it and the glass sealing strip 34, thereby reducing the frictional resistance between the two, so as to ensure the smoothness of the raising and lowering of the window glass 20. The arc-shaped first elastic block 442 has good buffering capacity, so that when the limiting member 44 is subjected to external force, it can absorb and disperse part of the external force through its own deformation. At the same time, the setting of the hollow groove 445 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 zero-step difference window glass bracket 300 can play its own supporting role while having good tolerance.
[0107] Furthermore, 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 other end of the arc-shaped segment 4421 that is suspended relative to the first rigid block 441, and is used to elastically abut against the glass sealing strip 34 in the length x direction of the vehicle. Here, the arc-shaped segment 4421 has a larger 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 34, thereby increasing the stability of the zero-step window glass bracket 300 in supporting the window glass 20, and making the movement of the window glass 20 more stable.
[0108] In this embodiment of the application, the length of the straight line segment 4422 is L, and its specific value is as described in the above embodiment, and will not be repeated here.
[0109] As shown in Figure 20, 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, it can absorb and disperse part of the force 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 avoiding damage to the connection structure under stress.
[0110] In this embodiment, the radius of the arc chamfer 4423 is R, and its specific value is as described in the above embodiment, and will not be repeated here.
[0111] In one embodiment of this application, the number of arc segments 4421 is set to two segments, 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 4423.
[0112] Please continue to refer to Figure 18. Along the length direction x of the vehicle, the maximum height of the hollow groove 445 is H, which is the distance between the straight segment 4422 and the first rigid block. Its specific value is as described in the above embodiment, and will not be repeated here.
[0113] This application also provides a vehicle, including the zero-step difference door side window system 100, the zero-step difference window glass guide rail system 200, or the zero-step difference window glass bracket 300 in any of the above embodiments.
[0114] In this embodiment, the zero-step differential door side window system and vehicle are configured with x-axis and y-axis limiting structures within the guide groove. The second side is then limited in the vehicle's length and width directions by the corresponding x-axis and y-axis limiting structures, respectively. At this point, the door pillar trim panel overlaps the guide rail unit, thus decoupling the glass limiting and lifting-related functional components from the decorative components. Consequently, the door pillar trim panel serves only a decorative function and no longer needs to cooperate with the guide rail to limit the glass bracket. Therefore, it is only necessary to install the door pillar trim panel onto the door pillar, greatly reducing the installation difficulty and improving assembly consistency. Simultaneously, since the door pillar trim panel no longer participates in limiting, assembly errors are reduced. That is, assembly errors in the door pillar trim panel will not affect the fitting accuracy between the glass bracket and the guide rail, which is beneficial for improving the stability of the glass bracket.
[0115] 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.
[0116] The above embodiments merely illustrate 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 protection scope of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
