Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, and in particular to a guide rail assembly of a door glass. In addition, the utility model also relates to a vehicle. Background Art

[0002] With the development of the automobile industry, more and more models pay attention to the overall streamline of the car to make the exterior of the vehicle more beautiful. Many models begin to use zero-face difference doors, that is, the door glass is flush with the outer panel of the door frame. For example, on the B-pillar side of the window frame, when the door glass is raised, the outer surface of the door glass is flush with the outer trim of the B-pillar, making the side of the car body streamlined, thereby reducing the wind resistance coefficient of the side of the vehicle. However, this puts higher requirements on the installation and layout of the door glass, as well as its lifting system.

[0003] As an important part of the door glass lifting system, the car glass lifting guide rail has two main functions: one is to serve as an installation carrier for the sealing strip, and together with the sealing strip and the glass, it plays a role in dust and water prevention; the other is to serve as a guiding mechanism for the glass lifting, which has a great influence on the smoothness of the lifting and lowering operation of the door glass.

[0004] For door glass with zero face difference, the glass needs to be arranged flush with the outer panel of the door frame while being guided and raised, so the traditional method of fixing the glass inside the lower glass guide rail cannot be used; and the existing guide rail design of door glass with zero face difference has the problem of poor structural stability. The limiting performance is insufficient during the lifting and lowering of the glass, and the guide rail, sealing strip, etc. are easy to move relative to each other, resulting in the wear of the guide components and the shaking of the glass during the lifting and lowering of the glass.

[0038] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0039] Embodiment 1

[0040] This embodiment relates to a guide rail assembly for a vehicle door glass, which can improve the guiding performance of the guide rail assembly; an exemplary structure thereof is as follows Figures 1 to 4 shown.

[0041] In general, the guide rail assembly of the door glass comprises a guide rail seat 1 mounted on the door frame, a guide rubber strip 2 arranged on the guide rail seat 1, and a guide bracket 4 arranged on the door glass 3, wherein the guide bracket 4 is guided in a guide groove 200 arranged on the guide rubber strip 2. At the same time, a guide rail groove 100 for mounting the guide rubber strip 2 is formed on the guide rail seat 1, and a plurality of clamping bosses 11 are arranged on the inner wall of the guide rail groove 100; a clamping groove 202 corresponding to each clamping boss 11 is arranged on the outer wall of the guide rubber strip 2, and each clamping boss 11 is clamped in the corresponding clamping groove 202 to fix the guide rubber strip 2 in the guide rail groove 100.

[0042] It should be pointed out that, based on the above-mentioned overall design concept, the technical solution of the utility model can adopt a variety of different specific implementation structures, forms or configuration sequences. For example, the clamping structure between the guide groove 100 of the guide rail seat 1 and the guide rubber strip 2 can be designed in a variety of different forms of specific structures. For the parts required for the implementation of the overall solution but not involved in the above-mentioned overall setting, reasonable and flexible designs can also be made with reference to the mature setting means in the field, the actual situation during implementation, etc. The specific implementation scheme described below in this embodiment is only one of the better solutions that can be formed by the above-mentioned various combinations and changes. In actual implementation, those skilled in the art can make flexible adjustments and improvements based on the actual situation. Obviously, the many solutions that can be formed by the above-mentioned various specific forms of combination and changes, as well as the specific implementation scheme of this embodiment, are all within the scope of protection of the utility model.

[0043] Based on the above design ideas, such as Figure 4 As shown, the guide rail assembly of the vehicle door glass of this embodiment mainly includes a guide rail seat 1, a guide rubber strip 2 and a guide bracket 4.

[0044] Specifically, if Figure 5 and Figure 6 As shown, the guide rail seat 1 of this embodiment includes a guide rail seat body 10 and a plurality of support arms 12 connected to the guide rail seat body 10; the guide rail groove 100 is located on the guide rail seat body 10, and the end of the support arm 12 is provided with a connector for connecting to the door frame. Providing a plurality of support arms 12 for the guide rail seat 1 facilitates the installation and fixation of the guide rail seat 1 on the door frame, which not only makes the setting of the installation connection point more flexible, but also ensures the installation reliability of the guide rail seat 1.

[0045] The connecting member includes a mounting bolt 121 embedded in the support arm 12. Of course, the above-mentioned connecting member can also be in the form of a screw, a rivet, etc. However, the connecting member in this embodiment is a mounting bolt 121 embedded in the support arm 12. By embedding the mounting bolt 121 in the support arm 12 and cooperating with a lock nut, the support arm 12 can be conveniently fixed to the door frame; this not only reduces the number of installation parts, but also improves the connection firmness between the support arm 12 and the door frame. In this embodiment, there are two support arms 12 arranged at intervals, and a mounting bolt 121 is embedded at the end of each support arm 12.

[0046] There are of course many options for the arrangement of the clamping boss 11. In the present embodiment, the guide rail seat body 10 includes an inner side wall 101, a bottom wall 103 and an outer side wall 102 connected in sequence; the above-mentioned guide rail groove 100 is formed by the inner side wall 101, the bottom wall 103 and the outer side wall 102. Specifically, the cross section of the guide rail seat body 10 is U-shaped, and the thickness of each wall panel such as the inner side wall 101, the outer side wall 102 and the bottom wall 103 can be set between 2mm and 5mm, for example, the wall thickness is set to 2.7mm. Based on this, the above-mentioned clamping boss 11 includes a plurality of lower bosses 112 arranged at intervals on the inner side wall 101 along the length direction of the guide rail groove 100 (which is also the length direction of the guide rail seat body 10), and a plurality of upper bosses 111 arranged at intervals on the outer side wall 102 along the length direction of the guide rail groove 100. The inner wall surface of the inner side wall 101 is provided with nine lower bosses 112, and the inner wall surface of the outer side wall 102 is provided with nine upper bosses 111 arranged at intervals. Each clamping boss 11 is evenly spaced, and the cross section of the clamping boss 11 is triangular, and the height of the clamping boss 11 is about 1.2 mm.

[0047] Obviously, the length direction of the guide rail seat body 10 is also the guiding movement direction of the guide bracket 4, and the door glass 3 is lifted and slid in this direction. Therefore, the trend of the guide rubber strip 2 and the guide rail seat body 10 should be consistent with the surface shape of the door glass 3; if the door glass 3 is flat, the guide rubber strip 2 and the guide rail seat body 10 can both be straight. If the door glass 3 has a certain curvature and forms an arc-shaped arch, the shape of the guide rubber strip 2 and the guide rail seat body 10 should also be designed to be an arc shape accordingly, and the curvature is consistent with the surface of the door glass 3. The curvature is consistent with the surface of the door glass 3, which can ensure that the door glass 3 is always tightly attached to the guide rubber strip 2 during the lifting process. In this way, the smooth guiding and sliding of the door glass 3 during the lifting process can be guaranteed, and the guide rail seat body 10 and the guide rubber strip 2 form an effective support for the door glass 3.

[0048] It should be pointed out that a lower boss 112 and an upper boss 111 are respectively arranged on the inner wall 101 and the outer wall 102 of the guide rail groove 100. The lower boss 112 and the upper boss 111 can form a clamping and fixing effect on the guide rubber strip 2 on the upper and lower sides of the guide rubber strip 2, thereby improving the clamping and fixing effect of the guide rubber strip 2 in the guide rail groove 100, and further reducing the possibility of the guide rubber strip 2 moving in the guide rail groove 100.

[0049] Furthermore, preferably, the upper bosses 111 and the lower bosses 112 should be arranged alternately along the length direction of the guide rail groove 100. Since the inner side wall 101 and the outer side wall 102 are arranged opposite to each other, the lower bosses 112 on the inner side wall 101 and the upper bosses 111 on the outer side wall 102 are arranged alternately to avoid the lower bosses 112 and the upper bosses 111 facing each other, which can reduce the influence of the clamping bosses 11 on the installation of the guide rubber strip 2, and facilitate the guide rubber strip 2 to be clamped into the guide rail groove 100 more smoothly; at the same time, the guide rubber strip 2 can be fixed more firmly in the guide rail groove 100.

[0050] like Figure 6 As shown, a plurality of process holes 15 are provided on the bottom wall 103 of the present embodiment corresponding to each upper boss 111 and each lower boss 112. By providing the process holes 15 on the bottom wall 103 of the guide rail groove 100, it is possible to save materials and reduce the weight of the guide rail seat 1, and it is also convenient to integrally inject the guide rail seat 1 and its upper boss 111 and lower boss 112.

[0051] like Figure 5 and Figure 6As shown, in order to improve the structural strength of the guide rail seat 1, some reinforcing ribs, reinforcing protrusions and other structures can also be set on the guide rail seat 1. In this embodiment, a plurality of first reinforcing ribs 13 are provided on the two support arms 12. Specifically, the support arm 12 includes an arm body 120 and a truncated cone formed at the end of the arm body 120. Three first reinforcing ribs 13 are arranged at intervals on the upper surface and the lower surface of each arm body 120, and the wall thickness of the first reinforcing ribs 13 can be set at about 3mm. Each first reinforcing rib 13 merges into a truncated cone-shaped structure at the end of the arm body 120, and the above-mentioned mounting bolts 121 are embedded in the truncated cone. The provision of the first reinforcing rib 13 can greatly improve the structural strength of the support arm 12, thereby providing strong support for the guide rail seat body 10 and preventing the guide rail seat 1 from being crushed during the lifting and lowering process of the door glass 3.

[0052] In addition, a plurality of second reinforcing ribs 14 are arranged on the side surface of the inner side wall 101 facing away from the guide rail groove 100, and these second reinforcing ribs 14 are arranged in a crisscross pattern and distributed in a grid pattern. The specific size of these second reinforcing ribs 14 can be reasonably set, and the thickness of the second reinforcing ribs 14 in this embodiment is 2.5 mm; moreover, each second reinforcing rib 14 runs through the entire length or width of the guide rail seat body 10, effectively enhancing the structural strength of the inner side wall 101 as the base plate of the guide rail seat body 10.

[0053] like Figure 7 As shown, in this embodiment, the guide rubber strip 2 includes a main body 20 and a sealing part 21. The guide groove 200 and the clamping groove 202 are both provided on the main body 20, and the main body 20 is clamped in the guide rail groove 100; the sealing part 21 is connected to the main body 20 and is located on the side of the guide bracket 4 facing away from the door glass 3; the sealing part 21 is extended from the main body 20 toward the door glass 3 and abuts against the door glass 3. The guide groove 200 has a notch 201 provided toward one side of the door glass 3, and the guide bracket 4 partially enters the guide groove 200 through the notch 201 to achieve the guiding movement of the guide bracket 4 in the guide groove 200; the sealing part 21 is connected to the main body 20 on one side of the notch 201.

[0054] The guide rubber strip 2 is designed to be composed of a main body 20 and a sealing part 21. The guide groove 200 on the main body 20 is responsible for the guiding movement function of the guide bracket 4, and the sealing part 21 plays a sealing role between the guide rail seat 1 and the door glass 3, which can better improve the design rationality and overall functional effect of the guide rubber strip 2. At the same time, the guide bracket 4 will be completely wrapped inside by the guide rubber strip 2, so that the guide bracket 4 can be well protected.

[0055] There are, of course, various designs for the specific structure of the corresponding sealing portion 21. Specifically, in this embodiment, a sealing lip is provided on the side of the end of the sealing portion 21 facing the door glass 3, and the sealing lip abuts against the inner side of the door glass 3; one or more sealing lips may be provided, and in this embodiment, two sealing lips are provided at intervals, namely, a first lip 211 and a second lip 212. The first lip 211 is located on the side of the second lip 212 away from the main body 20, the first lip 211 abuts against the door glass 3, and the second lip 212 abuts against the guide bracket 4 at the inner edge of the door glass 3, and is in effect abutted against the mounting strip 40 described below.

[0056] In addition, an abutment platform 213 is provided at the end of the sealing portion 21 of this embodiment on the side facing away from the door glass 3 . The top of the abutment platform 213 is abutted and connected to the guide rail seat 1 , and a corrugated sealing structure 22 is formed on the top of the abutment platform 213 .

[0057] By providing a sealing lip and abutment platform 213 at the end of the sealing portion 21, the sealing portion 21 can be well abutted and sealed on the door glass 3 and the guide rail seat 1, thereby improving the sealing effect of the guide rubber strip 2 between the guide rail seat 1 and the door glass 3. In this embodiment, the guide rail seat body 10 mainly includes an inner wall 101, a bottom wall 103 and an outer wall 102 which are connected in sequence to form a guide rail groove 100, wherein the inner wall 101 as a base plate has a larger size, the inner wall 101 is located on the inner side of the door glass 3, and the support arm 12 is connected to the inner wall 101. The abutment platform 213 is also abutted and matched with the inner wall 101, and a corrugated (or wave-shaped) sealing structure 22 is provided on the top of the abutment platform 213, which can further improve the sealing effect between the sealing portion 21 and the surface of the inner wall 101. Moreover, due to the setting of the sealing structure 22, the friction between the guide rubber strip 2 and the guide rail seat 1 can be greatly improved, thereby further preventing the guide rubber strip 2 from moving relative to the guide rail seat 1. When the guide rubber strip 2 provides guiding support for the door glass 3 during the lifting process, the problem of abnormal friction and noise caused by the slight displacement of the guide rubber strip 2 caused by the lifting of the door glass 3 can be avoided.

[0058] like Figure 8 As shown, the guide bracket 4 of this embodiment includes a mounting strip 40 bonded to the door glass 3, and a guide frame 41 assembled on the mounting strip 40. Specifically, the guide frame 41 of this embodiment includes a frame body 410 for connecting the mounting strip 40, and a plurality of guide blocks 411 spaced apart on the frame body 410; and an arched support rib 412 is connected between at least some of the adjacent guide blocks 411. The guide block 411 is set in the guide groove 200 of the guide rubber strip 2, and the arched part of the middle part of the support rib 412 is elastically supported on the inner wall of the guide groove 200.

[0059] The guide bracket 4 is designed to be composed of two parts, the mounting strip 40 and the guide bracket 41, so that they can be processed and constructed separately. Through the correspondingly arranged clamping holes, buckles, clamping grooves or connecting holes between the mounting strip 40 and the guide bracket 41, the guide bracket 41 can be conveniently assembled to the mounting strip 40, and the mounting strip 40 is bonded and fixed to the inner edge of the door glass 3, so that the entire guide bracket 4 is fixed to the door glass 3. The guide block 411 and the support rib 412 arranged on the guide bracket 41 cooperate with each other, the guide block 411 can play a good guiding role, and the support rib 412 can be elastically supported on the inner wall of the guide groove 200 to prevent the guide bracket 41 from moving in the guide groove 200, thereby further improving the guiding stability of the guide rail assembly.

[0060] The number of guide frames 41 can be flexibly set according to the overall length of the guide frame 4. One guide frame 41 can be set, or multiple guide frames 41 can be set at intervals in the length direction of the guide frame 4. In this embodiment, two guide frames 41 are set at intervals.

[0061] Depend on Figure 7 It can be seen that in the cross section of the entire guide rail assembly, the guide block 411 is restricted in the guide groove 200, and the guide frame 41 is in a T-shape as a whole, which can ensure that the guide block 411 slides stably in the guide groove 200 and prevent the guide frame 41 from escaping from the guide groove 200; the height of the guide block 411 should be set according to the size of the guide groove 200, and the height of the guide block 411 in this embodiment is 2.5mm. In this embodiment, the guide block 411 cooperates with the soft guide rubber strip 2 to achieve the limit of the lifting movement of the door glass 3, thereby ensuring the stability of the lifting movement of the door glass 3. Among them, the guide block 411 is restricted in the guide groove 200, and except for the lifting direction of the door glass 3, the guide frame 4 is well restricted by the guide rubber strip 2 in all other directions; the shaking of the door glass 3 relative to the guide rubber strip 2 can be avoided. The support rib 412 adopts an interference fit design. Under the elastic deformation of the support rib 412 , the support rib 412 can play a good supporting role between the door glass 3 and the guide rubber strip 2 .

[0062] To sum up, the guide rail assembly of the vehicle door glass of the present embodiment adopts the guiding matching form of the guide rail seat 1, the guide rubber strip 2 and the guide bracket 4, which provides convenient conditions for setting the zero surface difference between the outer surface of the vehicle door glass 3 and the vehicle door outer panel; the guide rubber strip 2 is fixed in the guide rail groove 100 of the guide rail seat 1 by a clamping structure, and the guide bracket 4 is slidingly arranged in the guide groove 200 of the guide rubber strip 2, which not only avoids the hard contact and friction between the guide bracket 4 and the guide rail seat 1, but also ensures the installation stability of the guide rubber strip 2, provides a good installation position and movement guiding foundation for the guide bracket 4, can improve the jitter problem of the vehicle door glass 3 during the lifting and lowering process, and enhances the stability of the lifting and lowering of the vehicle door glass 3, thereby improving the guiding performance of the guide rail assembly.
