Description
Technical Field
[0001] The invention relates to the technical field of frameless vehicle doors, and in particular to a single-track frameless vehicle door glass lifter and a vehicle. Background Art
[0002] Frameless doors are a signature feature of premium sports cars. With the accelerated trend of electrification and the booming new energy vehicle market in recent years, their application is no longer limited to high-end models. Many emerging automakers have entered the new energy vehicle field, and through technological innovation and cost optimization, frameless doors, once considered a symbol of luxury, have gradually become popular among mid-range models.
[0003] However, behind the widespread application of frameless door design, the technical bottleneck of frameless door glass lifters, as key components, has gradually emerged. At present, the mainstream frameless door glass lifters on the market generally adopt a double-track structure, which includes right front and rear guides and a large number of steel wire ropes. The overall structure is complex, which not only increases the weight of the lifter, but also increases the manufacturing cost. In addition, the assembly process of the double-track structure is cumbersome, requiring a high level of craftsmanship and a long assembly time, which undoubtedly poses a challenge to the efficiency of the automobile production line and affects the production rhythm of the workshop.
[0004] For mid- and low-end models, cost control is one of the key factors in market competition. The high cost and complex assembly process of the double-track structure frameless door glass lifter undoubtedly increase the overall manufacturing cost of the vehicle and reduce market competitiveness. Therefore, although the frameless door design is very popular in mid-end models, it is still difficult for mid- and low-end models to adopt frameless doors due to the technical bottleneck of the door glass lifter.
[0005] To sum up, in view of the problems of complex structure, high cost and difficult assembly of current frameless door glass lifters, the industry urgently needs to develop a new type of frameless door glass lifter to simplify the structure, reduce costs and improve assembly efficiency, so as to promote the widespread application of frameless door design in mid- and low-end models.

Through the combination of the two first nuts 11 and the two first double-ended adjustment studs 10, a simple and effective adjustment means is provided, so that the user or technician can easily adjust the position of the door glass in the Y direction.
[0028] like Figure 3 As shown, in a possible embodiment, the middle portion of the first adjustment bracket 15 is recessed toward one side of the guide rail 8 to form a first mounting portion 151, and the first adjustment bracket 15 is connected to the first connecting bracket 12 by the rotating shaft 14 through the first mounting portion 151. The provision of the first mounting portion not only facilitates the installation of the first adjustment bracket 15, but also can improve the strength of the first adjustment bracket 15.
[0029] like Figure 3 As shown, in a possible embodiment, a bushing 13 is installed at the position where the rotating shaft 14 cooperates with the first connecting bracket 12 and the first adjusting bracket 15. The setting of the bushing 13 reduces the friction and wear during the rotation process, improves the durability and reliability of the structure; and at the same time ensures the smoothness of the rotation of the first adjusting bracket 15 relative to the first connecting bracket 12.

Specifically, when the two first double-headed adjustment studs 10 in the upper adjustment mechanism 9 are adjusted at the same time, the overall Y-axis adjustment of the upper installation position can be achieved to adapt to different installation requirements. When the two second double-headed adjustment studs 16 in the lower adjustment mechanism 6 are adjusted at the same time, the overall Y-axis adjustment of the lower installation position can be achieved to adapt to different installation requirements. At the same time, when the lower adjustment mechanism 6 is adjusted in the Y direction, the guide rail 8 can be rotated relative to the rotating shaft 14 of the upper adjustment mechanism 9, thereby increasing the pre-bending amount of the door glass, ensuring that the door glass enters the groove normally, and eliminating the stress at the position of the upper adjustment mechanism 9.
[0036] The monorail frameless door glass lifter optimizes cost, weight and installation convenience, while providing precise door glass posture adjustment capabilities, thereby promoting the widespread application of frameless door design in mid- and low-end models.
[0037] In the embodiment of the present application, a single-track frameless door glass lifter is different from a conventional framed guide rail door glass lifter in that the posture of the door glass can be adjusted by an upper adjustment mechanism 9 and a lower adjustment mechanism 6 at the upper and lower installation positions of the guide rail 8. Compared with the conventional frameless door glass lifter, the posture adjustment of the door glass is also achieved without the need for a guide rail and a steel wire rope, so it has great advantages in cost, weight, and installation time.
[0038] like Figure 1 , Figure 2 and Figure 3 As shown, the detailed installation steps of the upper adjustment mechanism 9 are: First, two first nuts 11 are riveted to corresponding positions of the first adjustment bracket 15 to ensure a firm connection. The first nuts 11 are riveted nuts.
[0039] Then, the two first double-headed adjusting studs 10 are connected to the two first nuts 11 respectively, which provides a basis for the subsequent Y-direction adjustment.
[0040] Next, the first connecting bracket 12 is welded to the guide rail 8 to ensure a stable connection between the upper adjusting mechanism 9 and the guide rail 8 .
[0041] Finally, the first adjustment bracket 15 is connected to the first connection bracket 12 via the rotating shaft 14, and the bushing 13 is installed at the position of the rotating shaft 14 to reduce friction and wear.
[0042] The door glass can be adjusted in the Y direction by adjusting the first double-headed adjusting stud 10 , while the guide rail 8 is allowed to rotate around the rotating shaft 14 to adjust the pre-bending amount.
[0043] like Figure 1 , Figure 2 and Figure 4 As shown, the detailed installation steps of the lower adjustment mechanism 6 First, two second nuts 17 are riveted to corresponding positions of the second adjustment bracket 18 to ensure a firm connection. The second nuts 17 are riveted nuts. Then, the two second double-headed adjusting studs 16 are connected to the two second nuts 17 respectively, which provides a basis for the subsequent Y-direction adjustment.
[0044] Finally, the second adjustment bracket 18 is welded to the guide rail 8 .
[0045] The Y-direction adjustment of the door glass at the lower installation position is achieved by adjusting the second double-headed adjusting stud 16 .
[0046] In the embodiment of the present application, the Y direction is the width direction of the vehicle.
[0047] In an embodiment of the present application, a vehicle adopts a single-track frameless door glass lifter as in the embodiment of the present application. The single-track frameless door glass lifter not only simplifies the structure and reduces the cost, but also improves the assembly efficiency, so that the vehicle can complete the installation and commissioning of the door more quickly during the production process. At the same time, the single-track frameless door glass lifter can also achieve precise adjustment of the door glass posture.
[0048] The above-mentioned embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above-mentioned embodiments.
