[0008] In one embodiment, the slider includes a slider body and a guide rail preload member disposed on the slider body. The guide rail preload member has the groove, and the preload member is disposed on at least one of the guide rail preload member and the slider body.
[0009] In one embodiment, the number of guide rail pretensioners is multiple, and the multiple guide rail pretensioners are spaced apart along the sliding direction of the slider, with a pre-compression member between two adjacent guide rail pretensioners; The preload component is disposed on one of the two adjacent guide rail preload components and abuts against the other of the two adjacent guide rail preload components; Alternatively, two adjacent guide rail pretensioners may be connected as one unit through the preload member.
[0010] In one embodiment, the glass lifter includes an elastic buffer disposed on the guide rail preload member, the elastic buffer abutting against the slider body.
[0011] In one embodiment, the slider body has a mounting groove, and the guide rail preload includes a first segment having a first mating surface, a second segment having a second mating surface, and a connecting segment located between the first segment and the second segment. The first segment, the second segment, and the connecting segment enclose the sliding groove, and the end of the first segment facing away from the connecting segment and the end of the second segment facing away from the connecting segment are spaced apart to form an opening communicating with the sliding groove. The guide rail preload engages with the mounting groove, and the second segment is located on the side of the first segment facing away from the glass mating surface. The elastic buffer is disposed on the side of the first segment opposite to the second segment; And / or, the elastic buffer is disposed on the side of the second segment opposite to the first segment.
[0012] In one embodiment, the guide rail preload has a mounting post, and the elastic buffer is sleeved on the mounting post.
[0013] In one embodiment, the slide groove is disposed on one side of the slider along a first direction, and the side of the slider opposite to the slide groove along the first direction is used to install the door glass assembly; The slider includes a slider body with a glass mounting hole and a plurality of limiting blocks. The glass mounting hole passes through the slider body on opposite sides along the first direction. The plurality of limiting blocks are disposed on the side of the slider body away from the slide groove along the first direction and are spaced apart on the outer periphery of the glass mounting hole. The surfaces of each limiting block on the side away from the slider body together form a glass mating surface. And / or, the slider includes a limiting bracket disposed on the side of the slider body opposite to the slide groove along the first direction, for stopping the door glass assembly in the first direction; And / or, the window regulator includes a glass support disposed on the guide rail, the glass support protruding from the guide rail on the side near the door glass assembly and for abutting against the door glass assembly.
[0014] In one embodiment, the glass support is adjustablely disposed on the guide rail, and the protrusion length of the glass support is adjusted by moving relative to the guide rail.
[0015] In one embodiment, the glass support has an adjustment groove that extends spirally along the outer periphery of the glass support. The guide rail has a support mounting hole and a limiting protrusion disposed at the support mounting hole and protruding from the inner sidewall of the support mounting hole. The glass support is rotatably inserted through the support mounting hole, and the limiting protrusion is engaged with the adjustment groove.
[0016] Another embodiment of this application provides a vehicle door, including: Door glass assembly; In the aforementioned window regulator, the door glass assembly is mounted on the slider, and the slider slides along the guide rail to drive the door glass assembly to rise and fall.

The slider has a groove that slides with the guide rail, and the groove has a first mating surface and a second mating surface. The pre-pressing member is disposed on the slider and located outside the groove. During the sliding of the slider along the guide rail, the pre-pressing member elastically abuts against the guide rail, ensuring that at least one of the first and second mating surfaces remains in sliding contact with the guide rail. When the car door glass assembly shakes, the impact force is transmitted to the slider and the pre-pressing member. Because the pre-pressing member maintains elastic contact with the guide rail, it can convert a portion of the impact's kinetic energy into elastic potential energy through its own elastic deformation. Simultaneously, it applies an elastic compressive force to the guide rail, ensuring that at least one of the first and second mating surfaces remains in contact with the guide rail, thus reducing the relative shaking between the slider and the guide rail. This fundamentally avoids the shaking amplitude of the car door glass assembly, thereby alleviating the abnormal noise problem caused by shaking. Therefore, the window regulator in this application embodiment can effectively alleviate the abnormal noise problem caused by the shaking of the car door glass assembly. Attached Figure Description

Figure 1 The directions or positional relationships shown, "first direction" is based on the attached... Figure 3 The orientation or positional relationship shown is merely for the convenience of describing the embodiments of this application and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the embodiments of this application.
[0022] This application provides a vehicle that includes doors.
[0023] The vehicle also includes a body with side door openings, with doors that can be opened and closed at the side door openings of the body to open or close the side door openings.
[0024] Please see Figures 1 to 12 The door includes a window regulator 10 and a door glass assembly 20.
[0025] It should be noted that car doors include framed doors and frameless doors. Framed doors refer to doors with a complete window frame structure, within which the door glass assembly 20 rises, falls, and seals. In other words, the sealing and support of the door glass assembly 20 are achieved by the door's window frame structure. Frameless doors, on the other hand, have no window frame structure. The door glass assembly 20 directly fits and seals with the side door opening. In other words, the door glass assembly 20 relies on the side door opening for sealing and constraint.
[0026] Please see Figures 1 to 12 The window regulator 10 in this embodiment includes a guide rail 11, a slider 12, and a pre-pressurization component 13. The door window assembly 20 is mounted on the slider 12, and the slider 12 slides along the guide rail 11 to drive the door window assembly 20 to rise and fall along the guide rail 11.
[0027] The guide rail 11 provides a movement path for the slider 12, restricting the slider 12 to slide only along a predetermined movement path. The slider 12 is used to drive the door glass assembly 20 to slide along the guide rail 11.
[0028] The window regulator 10 also includes a drive assembly and a cable connected to the slider 12. The drive assembly drives the cable to pull the slider 12 to slide along the guide rail 11, thereby realizing the raising and lowering of the door window assembly 20.
[0029] In some embodiments, the window regulator 10 may include two guide rails 11 and two sliders 12, with each slider 12 corresponding to one of the guide rails 11. The two sliders 12 simultaneously drive the same door glass assembly 20 to rise and fall, forming a two-point clamping guide for the door glass assembly 20. This strictly limits the movement of the door glass assembly 20 in different directions. In the event of mechanical impact during door opening and closing, vibration during vehicle operation, or airflow impact on the door glass assembly 20, the two sliders 12 can effectively reduce glass shaking and reduce the probability of abnormal noise from the root.
[0030] Please see Figure 2 , Figure 3 , Figure 5 and Figure 6 The slider 12 has a groove 122a that slides with the guide rail 11. The groove 122a has a first mating surface 122a1 and a second mating surface 122a2. A preload member 13 is disposed on the slider 12 and located outside the groove 122a. During the sliding of the slider 12 along the guide rail 11, the preload member 13 elastically abuts against the guide rail 11 in a slidable manner, so that at least one of the first mating surface 122a1 and the second mating surface 122a2 remains in sliding contact with the guide rail 11.
[0031] The pre-compression member 13 is installed on the slider 12 and can slide relative to the guide rail 11 along a preset path together with the slider 12. At the same time, the pre-compression member 13 and the guide rail 11 are in elastic contact with each other to apply elastic compressive force to the guide rail 11. That is to say, during the sliding process, the pre-compression member 13 and the guide rail 11 always maintain an elastic contact state and will not separate. In other words, when the door glass assembly 20 is offset, the pre-compression member 13 can apply a stable elastic compressive force to the guide rail 11. Under the action of the elastic compressive force, the guide rail 11 remains in contact and pressed with at least one of the first mating surface 122a1 and the second mating surface 122a2, thereby achieving stable contact and no loosening during the relative sliding process of the slider 12 and the guide rail 11.
[0032] It should be noted that the sliding contact between at least one of the first mating surface 122a1 and the second mating surface 122a2 and the guide rail 11 does not mean that the slider 12 and the guide rail 11 only form a contact fit in a relative sliding state. Rather, it means that the slider 12 and the guide rail 11 maintain a continuous contact state throughout the entire engagement process. This includes the dynamic contact between at least one of the first mating surface 122a1 and the second mating surface 122a2 and the guide rail 11 when the slider 12 slides up and down along the guide rail 11, as well as the static contact between at least one of the first mating surface 122a1 and the second mating surface 122a2 and the guide rail 11 when the slider 12 is stationary relative to the guide rail 11 (such as when the door glass assembly 20 is stationary in any up or down position).
[0033] It is understandable that the initial mating state of the guide rail 11 with the first mating surface 122a1 and the second mating surface 122a2 can be abutting. That is, when the pre-compression member 13 does not apply elastic compressive force to the guide rail 11, the guide rail 11 is in contact with at least one of the first mating surface 122a1 and the second mating surface 122a2 and has compressive force. After the pre-compression member 13 applies elastic compressive force to the guide rail 11, the compressive force between the guide rail 11 and at least one of the first mating surface 122a1 and the second mating surface 122a2 increases.
[0034] In other embodiments, the initial mating state of the guide rail 11 with the first mating surface 122a1 and the second mating surface 122a2 can be contact. That is, when the pre-compression member 13 does not apply elastic compressive force to the guide rail 11, the guide rail 11 only contacts at least one of the first mating surface 122a1 and the second mating surface 122a2 without generating compressive force. After the pre-compression member 13 applies elastic compressive force to the guide rail 11, the guide rail 11 generates compressive force with at least one of the first mating surface 122a1 and the second mating surface 122a2.
[0035] In one specific embodiment, please refer to Figure 3 Both the first mating surface 122a1 and the second mating surface 122a2 are in sliding contact with the guide rail 11. In other embodiments, one of the first mating surface 122a1 and the second mating surface 122a2 is in sliding contact with the guide rail 11, while the other is not in contact.
[0036] The structure of the first mating surface 122a1 and the second mating surface 122a2 is not limited. For example, please refer to [link to relevant documentation]. Figure 6 The groove wall of the slide 122a has a protrusion to form a first mating surface 122a1 and a second mating surface 122a2. This reduces the sliding contact area between the guide rail 11 and the slide 122a, reduces the frictional resistance experienced by the slider 12 when sliding along the guide rail 11, and ensures the smoothness of the sliding process.
[0037] For example, please refer to Figure 2 , Figure 4 and Figure 5 A portion of the preload 13 can be bent toward the guide rail 11 to form an abutment portion 131, which slidably and elastically abuts against the guide rail 11.
[0038] The abutment portion 131 is a structure on the pre-compression member 13 that can slidably and elastically abut against the guide rail 11. By forming the abutment portion 131 by bending, the sliding contact area between the pre-compression member 13 and the guide rail 11 can be reduced, the frictional resistance experienced by the abutment portion 131 when sliding along the guide rail 11 can be reduced, and at the same time, the structure of the pre-compression member 13 can be simplified, production efficiency can be improved, and production costs can be reduced.
[0039] The glass lifter 10 in this embodiment includes a guide rail 11, a slider 12, and a pre-pressing member 13. The slider 12 has a groove 122a that slides with the guide rail 11. The groove 122a has a first mating surface 122a1 and a second mating surface 122a2. The pre-pressing member 13 is disposed on the slider 12 and located outside the groove 122a. During the sliding of the slider 12 along the guide rail 11, the pre-pressing member 13 elastically abuts against the guide rail 11 in a slidable manner, so that at least one of the first mating surface 122a1 and the second mating surface 122a2 remains in sliding contact with the guide rail 11. Next, when the door glass assembly 20 shakes, the impact force is transmitted to the slider 12 and the pre-pressure member 13. Since the pre-pressure member 13 maintains elastic contact with the guide rail 11, it can convert part of the impact kinetic energy into elastic potential energy through its own elastic deformation. At the same time, it applies elastic compressive force to the guide rail 11, so that at least one of the first mating surface 122a1 and the second mating surface 122a2 remains in contact with the guide rail 11, reducing the relative shaking between the slider 12 and the guide rail 11. This fundamentally avoids the shaking amplitude of the door glass assembly 20, thereby alleviating the abnormal noise problem caused by shaking. It can be seen that the window regulator 10 in this embodiment can effectively alleviate the abnormal noise problem caused by the shaking of the door glass assembly 20.
[0040] In some embodiments, please refer to Figure 3 and Figure 12 The guide rail 11 has a flange 11a that slides with the groove 122a. The first mating surface 122a1 and the second mating surface 122a2 are located on opposite sides of the flange 11a. The pre-pressing member 13 can slide elastically abut against the guide rail 11 on one side of the first mating surface 122a1 and the second mating surface 122a2, so that the other one of the first mating surface 122a1 and the second mating surface 122a2 keeps slidingly abutting against the flange 11a.
[0041] In other words, the flange 11a of the guide rail 11 extends into the sliding groove 122a to achieve a sliding engagement with the slider 12. It is understood that the flange 11a effectively improves the bending and torsional strength of the guide rail 11, ensuring its structural accuracy after long-term use and preventing problems such as glass lifting jamming and increased shaking caused by guide rail 11 deformation. Simultaneously, the flange 11a also improves the fit between the guide rail 11 and the first mating surface 122a1 and / or the second mating surface 122a2, effectively dispersing the pressure transmitted from the glass to the slider 12 and preventing tilting and jamming caused by excessive localized force on the slider 12.
[0042] For example, please refer to Figure 4 and Figure 5The pre-pressing member 13 is located on the side of the first mating surface 122a1. It abuts against the side of the flange 11a facing the first mating surface 122a1 so that the first mating surface 122a1 and the flange 11a remain in sliding contact. When the shaking of the door glass assembly 20 is transmitted to the slider 12, the pre-pressing member 13 absorbs the shaking of the slider 12 through elastic deformation so that the guide rail 11 always remains in sliding contact with the second mating surface 122a2.
[0043] For example, please refer to Figures 1 to 6 , Figure 8 and Figure 9 The slider 12 includes a slider body 121 and a guide rail pretensioner 122 disposed on the slider body 121. The guide rail pretensioner 122 has a groove 122a. A preload member 13 is disposed on at least one of the guide rail pretensioner 122 and the slider body 121.
[0044] The slider body 121 and the guide rail pretensioner 122 are two independent structures. The slider body 121 is used to connect with the door glass assembly 20. The guide rail pretensioner 122 can provide precise sliding guidance for the slider body 121, disperse the contact stress between the slider body 12 and the guide rail 11, and reduce local wear.
[0045] Preferably, the slider body 121 and the guide rail pretensioner 122 can be detachably connected, thereby allowing the selection of guide rail pretensioners 122 with different structures according to the specifications of the guide rail 11, thus improving the versatility of the slider 12.
[0046] The preload component 13 can be set on the guide rail preload component 122, or on the slider body 121, or on both the guide rail preload component 122 and the slider body 121.
[0047] More preferably, please refer to Figures 4 to 6 The pre-compression component 13 and the guide rail pre-tightening component 122 are an integral structure, that is, the pre-compression component 13 and the guide rail pre-tightening component 122 form a non-removable integral structure, which can reduce the assembly steps and improve the integrity between the pre-compression component 13 and the guide rail pre-tightening component 122, effectively preventing the pre-compression component 13 from loosening and falling off due to impact or long-term use.
[0048] Please see Figure 2 There are multiple guide rail pretensioners 122, which can be spaced apart along the sliding direction of the slider 12. A preload member 13 is provided between two adjacent guide rail pretensioners 122. The preload member 13 can be provided on one of the two adjacent guide rail pretensioners 122 and abuts against the other of the two adjacent guide rail pretensioners 122.
[0049] By setting multiple guide rail pretensioners 122, multi-point engagement with the guide rail 11 can be achieved, dispersing the impact and shaking transmitted from the door glass assembly 20 to the slider 12 and guide rail 11, improving the sliding engagement stability between the slider 12 and guide rail 11, thereby further alleviating the abnormal noise problem.
[0050] Figure 2 and Figure 5 The pre-compression member 13 includes a first connecting part 132 and a second connecting part 133 located on opposite sides of the abutment part 131. The first connecting part 132 is connected to one of the two adjacent guide rail pre-tightening members 122, and the second connecting part 133 abuts against the other of the two adjacent guide rail pre-tightening members 122, so that the abutment part 131 always maintains a slidable elastic abutment with the guide rail 11.
[0051] In other embodiments, two adjacent guide rail pretensioners 122 can be connected as one unit by a pre-compression member 13. That is, two adjacent guide rail pretensioners 122 and the pre-compression member 13 located between the two adjacent guide rail pretensioners 122 form an integral structure.
[0052] The material of the guide rail pretensioner 122 is not limited. Preferably, the guide rail pretensioner 122 can be a rigid plastic part, which can ensure that the guide rail pretensioner 122 has good structural strength, and ensure the stability of the fit with the guide rail 11 and the running stability of the door glass assembly 20.
[0053] In some embodiments, please refer to Figure 1 and Figure 7 The glass lifter 10 includes an elastic buffer 14 disposed on the guide rail pretensioner 122, and the elastic buffer 14 abuts against the slider body 121.
[0054] The elastic buffer 14 can compensate for the clearance between the guide rail preload 122 and the slider body 121 through elastic deformation.
[0055] The door glass assembly 20 includes a glass body 21 and a glass bracket 22. The glass bracket 22 is connected to the slider 12. It is understood that the glass body 21 generally has a pre-bending amount. The pre-bending amount refers to the bending arc and dimensional deviation of the glass body 21 along the Y / X direction of the vehicle body, which is pre-processed. Therefore, during the lifting and lowering of the door glass assembly 20, the glass body 21 will drive the slider 12 body to tilt outward or inward along the Y direction of the vehicle body. That is to say, a certain relative deflection will occur between the guide rail pretensioner 122 and the slider 12 body. The elastic buffer 14 can absorb the deflection between the guide rail pretensioner 122 and the slider 12 body to reduce the deflection of the guide rail pretensioner 122 relative to the guide rail 11, thereby preventing abnormal noise and / or excessive wear caused by stress concentration between the guide rail pretensioner 122 and the guide rail 11 when the door glass assembly 20 is lifted and lowered along the guide rail 11.
[0056] The way the elastic buffer 14 is disposed on the guide rail preload 122 is not limited. For example, please refer to [link to example]. Figures 4 to 7 The guide rail pretensioner 122 may have a mounting post 1224, and the elastic buffer 14 is sleeved on the mounting post 1224, thereby improving the assembly efficiency of the guide rail pretensioner 122 and the elastic buffer 14.
[0057] For example, please refer to Figure 3 and Figure 8 The slider body 121 may have a mounting groove 121a. The guide rail pretensioner 122 includes a first segment 1221 with a first mating surface 122a1, a second segment 1222 with a second mating surface 122a2, and a connecting segment 1223 located between the first segment 1221 and the second segment 1222. The first segment 1221, the second segment 1222, and the connecting segment 1223 form a sliding groove 122a. The ends of the first segment 1221 and the second segment 1222 that are opposite to the connecting segment 1223 are spaced apart to form an opening 122b communicating with the sliding groove 122a. The guide rail pretensioner 122 engages with the mounting groove 121a, and the second segment 1222 is located on the side of the first segment 1221 that is opposite to the glass mating surface 123a.
[0058] The flange 11a extends from the opening 122b into the groove 122a to mate with the first mating surface 122a1 and the second mating surface 122a2.
[0059] More preferably, please refer to Figure 3 and Figure 6 The cross-sectional shape of the slide groove 122a is approximately L-shaped, and the shape of the flange 11a is adapted to the shape of the slide groove 122a to improve the fit stability between the guide rail preload 122 and the guide rail 11, and effectively prevent the guide rail 11 from coming out of the slide groove 122a.
[0060] In some specific embodiments, the elastic buffer 14 can be disposed on the side of the first segment 1221 away from the second segment 1222. That is, the elastic buffer 14 is also disposed in the mounting groove 121a and located between the first segment 1221 and the groove wall of the mounting groove 121a. When a relative deflection occurs between the guide rail pretensioner 122 and the slider 12 body, the elastic buffer 14 can absorb the amount of deflection between the first segment 1221 and the slider 12 body.
[0061] In some specific embodiments, the elastic buffer 14 can be disposed on the side of the second segment 1222 away from the first segment 1221. That is, the elastic buffer 14 is also disposed in the mounting groove 121a and located between the first segment 1221 and the groove wall of the mounting groove 121a. When a relative deflection occurs between the guide rail pretensioner 122 and the slider 12 body, the elastic buffer 14 can absorb the amount of deflection between the first segment 1221 and the slider 12 body.
[0062] It is understood that the position of the elastic buffer 14 can be adjusted according to the pre-bending amount of the glass body 21 and the curvature and stress condition of the guide rail 11. For example, corresponding elastic buffers 14 can be set in the first segment 1221 and the second segment 1222, or the corresponding elastic buffer 14 can be set in only one of the first segment 1221 and the second segment 1222. In one specific embodiment, for a window regulator 10 that includes two guide rails 11 and two sliders 12, each slider 12 including a glass body and two guide rail pretensioners 122, a minimum of only one elastic buffer 14 can be provided, and a maximum of eight elastic buffers 14 can be provided. This allows the window regulator 10 to be adapted to the door glass assembly 20 of different car models, reducing the cost of research and development and production.
[0063] In other embodiments, the elastic buffer 14 may not be provided.
[0064] In some embodiments, please refer to Figure 3 The slide groove 122a is provided on one side of the slider 12 along the first direction, and the side of the slider 12 away from the slide groove 122a along the first direction can be used to install the door glass assembly 20.
[0065] In other words, the guide rail 11 and the door glass assembly 20 are located on opposite sides of the slider 12 along the first direction to ensure the smoothness of the door glass assembly 20 when it is raised and lowered. Preferably, the first direction can be the Y direction of the door.
[0066] Please see Figure 3 and Figure 9The slider 12 may include a slider body 121 having a glass mounting hole 121b and a plurality of limiting blocks 123. The glass mounting hole 121b passes through the slider body 121 on opposite sides along the first direction. The plurality of limiting blocks 123 are disposed on the side of the slider body 121 away from the slide groove 122a along the first direction and are spaced apart on the outer periphery of the glass mounting hole 121b. The surfaces of each limiting block 123 on the side away from the slider body 121 together form a glass mating surface 123a.
[0067] The glass mounting hole 121b is used to mate with the fastener 30 to achieve a fixed connection with the door glass assembly 20.
[0068] The glass mating surface 123a refers to the surface that contacts and fits against the glass bracket 22.
[0069] For ease of description, the surface of the slider body 121 facing away from the slide groove 122a along the first direction is called the first surface. The glass mounting hole 121b passes through the first surface. The surface on which the glass bracket 22 contacts and engages with the glass mating surface 123a is called the second surface. The limiting block 123 protrudes from the first surface. That is to say, the glass mating surface 123a and the first surface are located in two different virtual planes. When the second surface contacts and engages with the glass mating surface 123a, the second surface and the first surface are spaced apart.
[0070] In related technologies, the second surface of the glass bracket 22 directly contacts and adheres to the first surface of the slider body. If there is a flatness deviation between the first and second surfaces (such as local protrusions / depressions), the first and second surfaces are prone to slight deflection due to uneven force after they are adhered, resulting in angular errors. After the fasteners lock the slider body and the glass bracket, it will further cause the glass body to tilt, resulting in uneven appearance and abnormal wear of the sealing strip after the door glass assembly is assembled.
[0071] In this embodiment, by making multiple limiting blocks 123 protrude from the first surface of the slider body 121, a boss structure can be formed on the outer periphery of the glass mounting hole 121b. Since the area of the glass mating surface 123a is smaller than the area of the first surface and is not in the same virtual plane as the outer periphery of the glass mounting hole 121b, the tilting problem of the glass body 21 caused by the difference in flatness can be effectively alleviated.
[0072] In addition, the multiple limit blocks 123 are spaced apart to form a channel for water to flow out, which can prevent the glass bracket 22 and the slider 12 body from rusting due to water accumulation.
[0073] For example, please refer to Figure 9The slider 12 includes a limiting bracket 124, which is disposed on the side of the slider body 121 away from the slide groove 122a in the first direction, so as to stop the door glass assembly 20 in the first direction. That is, during the assembly process of the slider 12 and the door glass assembly 20, the limiting bracket 124 can limit the door glass assembly 20 in the first direction to improve the assembly efficiency of the slider 12 and the door glass assembly 20.
[0074] In some embodiments, please refer to Figures 10 to 12 The window regulator 10 may include a glass support 15 disposed on the guide rail 11. The glass support 15 protrudes from the side of the guide rail 11 near the door glass assembly 20 and is used to abut against the door glass assembly 20.
[0075] The glass support 15 abuts against the door glass assembly 20 to limit the door glass in a first direction.
[0076] Understandably, for a glass body 21 with a pre-bending amount, after the door glass assembly 20 is assembled onto the window regulator 10, the upper part of the glass body 21 will tilt towards the inside of the vehicle, and the door sheet metal and internal parts of the door may scratch the glass body 21.
[0077] For the window regulator 10 of the frameless door, in order to protect the glass body 21 from scratches, the relevant technology is to adjust the assembly sequence of the door components, first assembling the outer water cutter, and then assembling the door glass assembly 20. The outer water cutter can protect the glass body 21 from scratches. However, the door opening width (the width of the frame opening 122b reserved in the body for installing the door) is limited. After assembling the outer water cutter, it is difficult to assemble the glass body 21 in the remaining door opening space, which seriously affects the assembly efficiency and production cycle of the door glass assembly 20.
[0078] Therefore, by setting a glass support 15 on the guide rail 11, the tilt angle of the glass body 21 is limited by the glass support 15, so as to avoid the glass body 21 being scratched by the door sheet metal and / or the parts inside the door. At the same time, there is no need to change the assembly sequence of the door parts, which can avoid affecting the assembly efficiency and production cycle of the door glass assembly 20.
[0079] For example, Figures 10 to 12 The glass support 15 is adjustablely disposed on the guide rail 11, and the protrusion length of the glass support 15 can be adjusted by moving relative to the guide rail 11.
[0080] By adjusting the protruding length of the glass support 15, it can be adapted to glass bodies 21 with different pre-bending amounts. In other words, the glass support 15 can be adapted to the door glass assembly 20 of different car models without redesigning the structure of the glass support 15. This can improve the efficiency of vehicle assembly and maintenance, and reduce the cost of research and development and production.
[0081] Please continue reading. Figures 10 to 12 The glass support 15 may have an adjustment groove 15a, which extends spirally along the outer periphery of the glass support 15. The guide rail 11 has a support mounting hole 11b and a limiting protrusion 11c provided at the support mounting hole 11b and protruding from the inner wall of the support mounting hole 11b. The glass support 15 is rotatably inserted through the support mounting hole 11b, and the limiting protrusion 11c is engaged in the adjustment groove 15a.
[0082] The limiting protrusion 11c is used to fix the glass support 15 relatively, preventing the glass support 15 from moving when it abuts against the glass body 21. Since the adjusting groove 15a extends spirally along the outer periphery of the glass support 15, the position of the limiting protrusion 11c in the adjusting groove 15a can be adjusted simply by rotating the glass support 15, thereby adjusting the protrusion length of the glass support 15. The operation is simple and efficient, which can greatly improve the assembly efficiency of the door glass assembly 20.
