Description

Technical Field

[0001] The present invention relates to the technical field of frameless vehicle doors, and in particular to a monorail frameless vehicle door glass lifter and a vehicle. Background Art

[0002] Frameless doors, a hallmark of luxury sports cars, have expanded beyond high-end models in recent years with the accelerating trend toward electrification and the booming new energy vehicle market. Numerous emerging automakers have entered the new energy vehicle market, leveraging technological innovation and cost optimization to make frameless doors, once considered a symbol of luxury, increasingly common in mid-range models.

[0003] However, amidst the widespread adoption of frameless door designs, technical bottlenecks are gradually emerging for key components such as frameless door glass lifters. Currently, mainstream frameless door glass lifters on the market generally utilize a dual-track structure, consisting of right front and rear rails and a large number of steel cables. This complex overall structure not only increases the lifter's weight but also raises manufacturing costs. Furthermore, the assembly process for this dual-track structure is cumbersome, requiring advanced craftsmanship and a long assembly time. This undoubtedly poses a challenge to the efficiency of automotive production lines and affects the production cycle.

[0004] For mid-range and low-end vehicles, cost control is a key factor in market competition. The high cost and complex assembly process of dual-track frameless door glass regulators undoubtedly increase overall vehicle manufacturing costs and reduce market competitiveness. Therefore, although frameless door designs are highly favored in mid-range vehicles, technical bottlenecks in door glass regulators still make their adoption difficult for mid-range and low-end models.

[0005] To sum up, in view of the problems of complex structure, high cost and difficult assembly of the current single-track frameless door glass lifter, the industry urgently needs to develop a new type of single-track frameless door glass lifter to simplify the structure, reduce costs and improve assembly efficiency, thereby promoting the widespread application of frameless door design in mid- and low-end models. Summary of the Invention

[0006] The object of the present invention is to provide a single-track frameless door glass lifter and a vehicle, so as to adjust the posture of the door glass, simplify the structure, reduce the cost, and improve the assembly efficiency.

[0007] In a first aspect, the present invention provides a single-track frameless door glass lifter, comprising a guide rail, a door glass bracket slidably disposed on the guide rail, an upper steel wire rope and a lower steel wire rope respectively connected to the door glass bracket, and a drive unit respectively connected to the upper steel wire rope and the lower steel wire rope, and further comprising: An upper adjustment mechanism, comprising a first adjustment bracket and a first connecting bracket, wherein the first adjustment bracket is provided with a first Y-axis adjustment portion, the first adjustment bracket is connected to the first connecting bracket via a first rotating shaft, and the first connecting bracket is connected to the guide rail; a lower adjustment mechanism comprising a mounting bracket assembly and a second adjustment bracket assembly, wherein the mounting bracket assembly is connected to the guide rail, the second adjustment bracket assembly is connected to the mounting bracket assembly via a second rotating shaft, and the second adjustment bracket assembly is provided with a second Y-axis adjustment portion; The upper adjustment mechanism and the lower adjustment mechanism can respectively realize Y-axis adjustment of the door glass and allow the guide rail to rotate around the first rotation axis and the second rotation axis respectively; The Y direction is the width direction of the vehicle.

[0008] Optionally, the first Y-axis adjustment portion includes first nuts symmetrically disposed on both ends of the first adjustment bracket, and first double-ended adjustment studs connected to the first nuts. The combination of the first nuts and the first double-ended adjustment studs provides a simple and effective adjustment method, allowing users or technicians to easily adjust the position of the door glass in the Y-axis.

[0009] Optionally, a first bushing is installed at the position where the first shaft cooperates with the first connecting bracket and the first adjusting bracket. The arrangement of the first bushing reduces friction and wear during the rotation process, thereby improving the durability and reliability of the structure. Optionally, the mounting bracket assembly includes a mounting bracket and second nuts symmetrically disposed at both ends of the mounting bracket, wherein the mounting bracket is connected to the guide rail via assembly bolts via the second nuts. The design of the mounting bracket and the second nuts achieves a secure connection between the lower adjustment mechanism and the guide rail.

[0010] Optionally, the second adjustment bracket assembly includes a second connecting bracket and a second adjustment bracket, wherein the second adjustment bracket is fixed to the second connecting bracket, and the second connecting bracket is connected to the mounting bracket via a second rotating shaft. The design of the second adjustment bracket assembly allows for more precise adjustment of the door glass.

[0011] Optionally, the second Y-axis adjustment portion includes a third nut mounted on the second adjustment bracket and a second double-ended adjustment stud connected to the third nut. The second Y-axis adjustment portion provides further adjustment capability for the Y-axis position of the door glass, enhancing the adaptability and flexibility of the lifter structure.

[0012] Optionally, a second bushing is provided at the position where the second rotating shaft cooperates with the mounting bracket and the second connecting bracket. The design of the second bushing reduces friction and wear during the rotation process, thereby improving the durability and reliability of the structure.

[0013] Optionally, the system further comprises an upper guide wheel disposed at the upper end of the guide rail, wherein the upper wire rope passes over the upper guide wheel and is connected to the driving unit. The design of the upper guide wheel ensures the smooth operation of the upper wire rope during the lifting process, reducing friction and wear.

[0014] Optionally, the system further comprises a lower guide wheel provided at the lower end of the guide rail, wherein the lower wire rope passes over the lower guide wheel and is connected to the driving unit. The design of the lower guide wheel ensures the smooth operation of the lower wire rope during the lifting process, reducing friction and wear.

[0015] In a second aspect, a vehicle according to the present invention adopts the single-track frameless door glass lifter according to the present invention.

[0016] Beneficial effects of the present invention: (1) The present invention enables both the upper and lower mounting positions of the assembled single-track frameless door glass lifter to be adjusted in the Y direction by adding an upper adjustment mechanism and a lower adjustment mechanism. When the two first double-headed adjustment studs of the upper adjustment mechanism are adjusted simultaneously, the overall Y direction adjustment of the upper mounting position can be achieved. Since the lower adjustment mechanism also has a second rotating shaft, when one of the first double-headed adjustment studs of the upper adjustment mechanism is adjusted, the door glass can be rotated around the first rotating shaft and the guide rail. In addition, since the upper adjustment mechanism has a first rotating shaft, when the second double-headed adjustment stud of the lower adjustment mechanism is adjusted, the door glass can also be rotated around the first rotating shaft, thereby increasing the pre-bending amount of the door glass in the Y direction, ensuring that the door glass is normally slotted while eliminating the stress at the position of the upper adjustment mechanism.

[0017] (2) Compared with conventional dual-rail frameless door glass lifters, the present invention eliminates at least one rail and corresponding steel wire rope, which directly reduces material costs. It also simplifies the structure, reduces the complexity of the manufacturing and assembly processes, and thus reduces production costs.

[0018] (3) Since the present invention eliminates some guide rails and steel ropes, the weight of the entire lifter structure is significantly reduced, which is of great significance for improving the fuel economy of the vehicle or extending the cruising range of electric vehicles.

[0019] (4) The structure of the present invention is compact and the installation steps are relatively simplified, which reduces the installation time and labor costs and improves production efficiency.

[0020] In summary, the present invention optimizes cost, weight, and installation convenience through innovative design, while providing precise door glass posture adjustment capabilities, thereby promoting the widespread application of frameless door design in mid- and low-end models.

[0022] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art will be able to understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for the purpose of illustrating the present invention and are not intended to limit the scope of protection of the present invention.

[0023] like Figures 1 to 5 As shown, in an embodiment of the present application, a single-track frameless door glass regulator includes a drive unit 1, an upper wire rope 2, an upper guide wheel 3, a door glass bracket 4, a guide rail 6, a lower guide wheel 8, a lower wire rope 9, an upper adjustment mechanism 5, and a lower adjustment mechanism 7. Compared to a conventional framed guide rail door glass regulator, the drive unit 1, upper wire rope 2, upper guide wheel 3, door glass bracket 4, guide rail 6, lower guide wheel 8, and lower wire rope 9 are identical to the conventional structure, with the main difference being the addition of the upper adjustment mechanism 5 and the lower adjustment mechanism 7.

[0024] like Figure 1 and Figure 2As shown, in the embodiment of the present application, the door glass bracket 4 is slidably mounted on a guide rail 6. The door glass bracket 4 is used to support the door glass. The guide rail 6 provides a sliding track for the door glass bracket 4, ensuring the smooth lifting and lowering of the door glass. The upper guide wheel 3 and the lower guide wheel 8 are respectively arranged at the upper and lower ends of the guide rail 6. The upper guide wheel 3 is used to guide the movement direction of the upper steel wire rope 2, and the lower guide wheel 8 is used to guide the movement direction of the lower steel wire rope 9. The upper steel wire rope 2 and the lower steel wire rope 9 are respectively connected to the door glass bracket 4. The upper steel wire rope 2 is connected to the drive unit 1 after passing through the upper guide wheel 3, and the lower steel wire rope 9 is connected to the drive unit 1 after passing through the lower guide wheel 8. The drive unit 1 is responsible for providing lifting power, driving the movement of the upper steel wire rope 2 and the lower steel wire rope 9, thereby achieving the raising and lowering movement of the door glass.

[0025] like Figure 1 and Figure 2 As shown, in the embodiment of the present application, the upper adjustment mechanism 5 and the lower adjustment mechanism 7 can respectively realize Y-axis adjustment of the door glass, and allow the guide rail 6 to rotate around the first rotation axis and the second rotation axis respectively to adjust the pre-bending amount of the door glass.

[0026] like Figure 3 As shown, in the embodiment of the present application, the upper adjustment mechanism 5 includes a first adjustment bracket 15 and a first connecting bracket 12. The first adjustment bracket 15 is provided with a first Y-axis adjustment portion. The first adjustment bracket 15 is connected to the first connecting bracket 12 via a first rotating shaft 14. The first connecting bracket 12 is welded to the guide rail 6. The axis of the first rotating shaft 14 is perpendicular to the longitudinal direction of the guide rail 6.

[0027] like Figure 3 As shown, in one possible embodiment, the first Y-axis adjustment portion includes first nuts 11 symmetrically arranged on both ends of a first adjustment bracket 15, and a first double-ended adjustment stud 10 connected to the first nut 11. The combination of the first nut 11 and the first double-ended adjustment stud 10 provides a simple and effective adjustment method, allowing users or technicians to easily adjust the position of the door glass in the Y direction.

[0028] like Figure 3 As shown, in one possible embodiment, a first bushing 13 is installed at the position where the first rotating shaft 14 mates with the first connecting bracket 12 and the first adjustment bracket 15. The provision of the first bushing 13 reduces friction and wear during rotation, improving the durability and reliability of the structure; it also ensures smooth rotation of the first adjustment bracket 15 relative to the first connecting bracket 12.

[0029] like Figure 4 As shown, in a possible embodiment, a welding position 16 is provided on the first connecting bracket 12 , and the upper adjustment mechanism 5 is welded to the guide rail 6 via the welding position 16 on the first connecting bracket 12 .

[0030] like Figure 5 As shown, in this embodiment of the present application, the lower adjustment mechanism 7 includes a mounting bracket assembly and a second adjustment bracket assembly. The mounting bracket assembly is connected to the guide rail 6. The second adjustment bracket assembly is connected to the mounting bracket assembly via a second rotating shaft 23. The second adjustment bracket assembly is provided with a second Y-axis adjustment portion. The axis of the second rotating shaft 23 is aligned with the longitudinal direction of the guide rail 6.

[0031] like Figure 5 As shown, in one possible embodiment, the mounting bracket assembly includes a mounting bracket 24 and second nuts 21 symmetrically disposed at both ends of the mounting bracket 24. The mounting bracket 24 is connected to the guide rail 6 via assembly bolts 20 via the second nuts 21. The design of the mounting bracket 24 and the second nuts 21 achieves a secure connection between the lower adjustment mechanism 7 and the guide rail 6.

[0032] like Figure 5 As shown, in one possible embodiment, the second adjustment bracket assembly includes a second connecting bracket 25 and a second adjustment bracket 18. The second adjustment bracket 18 is welded and fixed to the second connecting bracket 25. The second connecting bracket 25 is connected to the mounting bracket 24 via a second rotating shaft 23. The design of the second adjustment bracket assembly allows for more precise adjustment of the door glass.

[0033] like Figure 5 As shown, in one possible embodiment, the second Y-axis adjustment portion includes a third nut 19 disposed on a second adjustment bracket 18, and a second double-ended adjustment stud 17 connected to the third nut 19. The second Y-axis adjustment portion provides further adjustment capability for the Y-axis position of the door glass.

[0034] like Figure 5 As shown, in one possible embodiment, a second bushing 22 is provided where the second rotating shaft 23 mates with the mounting bracket 24 and the second connecting bracket 25. The design of the second bushing 22 reduces friction and wear during rotation, improving the durability and reliability of the structure. It also ensures smooth rotation of the mounting bracket 24 relative to the second connecting bracket 25.

[0035] In the embodiment of the present application, the main working principle of the single-track frameless door glass lifter is: When the motor in the drive unit 1 starts and rotates, it drives the upper and lower cables 2 and 9 in synchronous motion. This movement further drives the door glass bracket 4 to smoothly move up and down along the guide rails 6, thereby raising and lowering the door glass. During this movement, the upper and lower guide wheels 3 and 8 play a crucial guiding role, ensuring the accurate trajectory of the upper and lower cables 2 and 9.

[0036] This single-track frameless door glass lifter is unique in its addition of an upper adjustment mechanism 5 and a lower adjustment mechanism 7, located at the upper and lower mounting locations of the guide rail 6, respectively. This allows for Y-axis adjustment at both the upper and lower mounting locations of the guide rail 6. Specifically, simultaneous adjustment of the two first double-ended adjustment studs 10 in the upper adjustment mechanism 5 enables overall Y-axis adjustment of the upper mounting location to accommodate various installation requirements. The lower adjustment mechanism 7 is equipped with a second rotation axis 23. Adjusting either of the first double-ended adjustment studs 10 in the upper adjustment mechanism 5 allows the door glass to rotate about the second rotation axis 23 and the guide rail 6, further enhancing adjustment flexibility.

[0037] Furthermore, the first rotating shaft 14 of the upper adjustment mechanism 5 also plays a crucial role. Adjusting the second double-ended adjusting stud 17 in the lower adjustment mechanism 7 allows the door glass to rotate about the first rotating shaft 14, further increasing the amount of pre-bend in the Y direction. This design not only ensures smooth insertion of the door glass into the slot but also effectively eliminates potential stress at the upper mounting position, enhancing the stability and durability of the entire lifter.

[0038] This single-track frameless door glass lifter optimizes cost, weight, and installation ease through its innovative design, while providing precise door glass posture adjustment capabilities, thereby promoting the widespread adoption of frameless door designs in mid- and low-end vehicles.

[0039] In the embodiments of this application, a single-track frameless door glass regulator differs significantly from conventional framed guide rail door glass regulators in that the door glass position can be adjusted at the upper and lower mounting locations of the guide rail 6 via upper and lower adjustment mechanisms 5 and 7. Furthermore, compared to conventional dual-track frameless door glass regulators, this regulator eliminates one guide rail and wire rope while still achieving position adjustment for the door glass. This offers significant advantages in cost, weight, and installation time.

[0040] like Figure 1 、 Figure 2 and Figure 3 As shown, the detailed installation steps of the upper adjustment mechanism 5 are: 1. Rivet the first nut 11 to the first adjustment bracket 15 to ensure a firm connection.

[0041] 2. Connect the first double-ended adjustment stud 10 to the first nut 11 to provide a basis for subsequent Y-axis adjustment.

[0043] 4. Connect the first adjustment bracket 15 to the first connecting bracket 12 through the first rotating shaft 14, and install the first bushing 13 to reduce friction and wear.

[0044] 5. By adjusting the first double-ended adjusting stud 10, the Y-axis adjustment of the door glass is achieved, and the guide rail 6 is allowed to rotate around the first rotating shaft 14 to adjust the pre-bending amount.

[0045] like Figure 1 、 Figure 2 and Figure 5 As shown, the detailed installation steps of the lower adjustment mechanism 7 1. Connect the second adjustment bracket 18 and the second connecting bracket 25 by spot welding.

[0046] 2. Rivet the third nut 19 to the second adjustment bracket 18 to provide a basis for subsequent Y-axis adjustment.

[0047] 3. Connect the second double-ended adjustment stud 17 to the third nut 19 to prepare for Y-axis adjustment.

[0048] 4. Weld the second nut 21 to the mounting bracket 24 to prepare for connection to the guide rail 6.

[0049] 5. Assemble and connect the mounting bracket 24 and the second connecting bracket 25 through the second rotating shaft 23 and the second bushing 22 to ensure a stable connection between the lower adjustment mechanism 7 and the guide rail 6 and reduce friction.

[0050] 6. Use the assembly bolts 20 to connect and secure the lower adjustment mechanism 7 to the guide rail 6.

[0051] 7. By adjusting the second double-ended adjusting stud 17, the door glass can be adjusted in the Y direction and the guide rail 6 can be allowed to rotate around the second rotation axis 23 to adjust the pre-bend.

[0052] In the embodiment of the present application, the Y direction is the width direction of the vehicle.

[0053] In an embodiment of the present application, a vehicle utilizes a monorail frameless door glass regulator as described in the embodiment of the present application. This monorail frameless door glass regulator not only simplifies the structure and reduces costs, but also improves assembly efficiency, enabling faster door installation and commissioning during vehicle production. Furthermore, this monorail frameless door glass regulator enables precise adjustment of the door glass's posture.

[0054] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited to the above embodiments.
