Abstract
Description
Technical Field
[0001] This application pertains to the field of automotive body structure, specifically to a window regulator, a frameless door, and a vehicle. Background Technology
[0002] In existing automotive structures, frameless door windows require a window regulator with Y-axis adjustment functionality to ensure a good seal with the weatherstripping and a uniform surface difference with the trim panels. Current window regulators adjust the lower part of the guide rail in the Y-axis, thereby adjusting the glass mounted on the glass bracket. This Y-axis adjustment design requires additional structures on the guide rail, increasing the number of parts and raising the mold costs for guide rail production. Utility Model Content
[0003] This application provides a window regulator, a frameless door, and a vehicle, which reduces the number of parts and lowers the manufacturing cost of the parts while ensuring the Y-axis adjustment of the window glass.
[0004] The technical solution of this utility model is as follows: On one hand, this application provides a vehicle window regulator, including: a guide rail and a glass bracket; the glass bracket includes: The bracket body used to hold the car window glass; A slider body, which is slidably arranged on the guide rail; The slider body is connected to the bracket body via a connecting structure; The slider body adjusts the position of the lower part of the bracket body in the lateral direction of the vehicle through the adjustment structure, thereby achieving a reverse adjustment of the position of the window glass clamped by the upper part of the bracket body in the lateral direction of the vehicle.
[0005] Preferably, the connection structure includes: Connecting bolts connect the slider body and the bracket body.
[0006] Preferably, the adjustment structure includes: An adjusting bolt, one end of which passes through the slider body and is screwed into a threaded groove on the bracket body for fixation.
[0007] Preferably, the upper and lower ends of the guide rail are respectively provided with mounting holes for assembly with the door panel.
[0008] Preferably, the guide rail is manufactured using a roll forming process.
[0009] Preferably, the cross-section of the guide rail is designed with multiple bends.
[0010] Preferably, when the guide rail is manufactured using a roll forming process, the transverse cross-sectional width is greater than 70 mm and the longitudinal depth is greater than 15 mm.
[0011] Preferably, the thickness of the guide rail is 1.5 mm or more.
[0012] On the other hand, this application also provides a frameless car door in which the aforementioned window regulator is installed.
[0013] On the other hand, this application also provides a vehicle including the aforementioned frameless door.
[0014] The beneficial effects of this utility model are as follows: By moving the Y-axis adjustment mechanism for the car window glass from the original guide rail to the glass bracket, the hinge shaft, hinge nut, and rivet nut structures on the guide rail can be eliminated, reducing the number of parts, enabling a lightweight design of the door system, and lowering manufacturing costs.
[0015] Furthermore, since the guide rail does not require holes or mounting space for these structures, the manufacturing process can be changed to a roll forming process, and the mold can be changed from a complex stamping process to a universal roll forming mold. Verification has shown that after the guide rail process was improved, the material utilization rate increased from 50%~60% with stamping to over 95% with roll forming.
[0016] The original structural design for adjusting the Y-axis of the car window glass has been reduced from multiple parts, such as hinge shaft, hinge nut, rivet nut, mounting bolt and adjusting bolt, to a single adjustment decoupling strand. The multi-part, multi-directional hole and shaft fit has been simplified to a single-part, single-directional hole and shaft fit, thereby improving the Y-axis adjustment accuracy.
[0017] In addition, by eliminating the adjusting bolt at the lower end of the guide rail, the guide rail will not move in the Y direction and will not encroach on the cross-sectional space of the anti-collision beam, so that the anti-collision beam has enough height space for structural reinforcement. At the same time, it can also save the lower space of the door and provide more possibilities for the lower door design. Attached Figure Description

Detailed Implementation
[0019] To make the objectives, advantages, and features of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the drawings are all in a very simplified form and are not drawn to scale, and are only used to facilitate and clarify the explanation of the objectives of the embodiments of this utility model. Furthermore, the structures shown in the drawings are often part of the actual structure. In particular, different drawings may emphasize different aspects and sometimes use different scales.
[0020] Reference Figures 1-3 In traditional car window regulators, to achieve Y-axis adjustment of the window glass, the lower part of the guide rail 1 is adjusted in the Y direction, which in turn drives the window glass mounted on the glass bracket 2 to adjust the Y-axis gap. Specifically, the upper end of the guide rail 1 is assembled with a hinge shaft 6 and a hinge nut 5, which are connected to the hinge nut 5 by mounting bolts 3 passing through the door panel and the guide rail 1. A rivet nut 7 is installed at the lower part of the guide rail 1, and an adjusting bolt 4 is connected to the inner door panel through the rivet nut 7. When the Y-axis position of the window glass needs to be adjusted, the position of the adjusting bolt 4 relative to the rivet nut 7 is adjusted, and the upper end of the guide rail 1 rotates relative to the hinge nut 5, causing the guide rail 1 to tilt in the Y direction. As a result, the glass bracket 2 mounted on the guide rail 1 tilts in the Y direction, causing the window glass it holds to tilt in the Y direction, thus achieving the Y-axis position adjustment of the window glass.
[0021] Due to the presence of hinge shaft 6, hinge nut 5, and rivet nut 7, guide rail 1 needs to have holes and installation space to accommodate these parts. Therefore, guide rail 1 can only be manufactured using stamping technology, and multiple molds are required during manufacturing, which increases the manufacturing cost of the guide rail.
[0022] Furthermore, the inclusion of hinge shaft 6, hinge nut 5, and rivet nut 7 results in a large number of components in the window regulator, which hinders the lightweight design of the door system and increases costs.
[0023] Reference Figure 4 and Figure 5 This application provides a vehicle window regulator, including: a guide rail 201 and a glass bracket 202; the glass bracket 202 includes: Bracket body for holding vehicle window glass 2021; The slider body 2022 is slidably arranged on the guide rail 201; The slider body 2022 is connected to the bracket body 2021 via a connecting structure; The slider body 2022 adjusts the position of the lower part of the bracket body 2021 in the lateral direction of the vehicle through the adjustment structure, thereby realizing the reverse adjustment of the position of the window glass clamped by the upper part of the bracket body 2021 in the lateral direction of the vehicle.
[0024] By moving the Y-axis adjustment mechanism for the car window glass from the original guide rail to the glass bracket, the hinge shaft, hinge nut, and rivet nut structures on the guide rail can be eliminated, reducing the number of parts, enabling a lightweight design of the door system, and lowering manufacturing costs.
[0025] Furthermore, since the guide rail 201 in this embodiment does not require the holes and installation space of these structures, the manufacturing process of the guide rail 201 can be changed to a roll forming process, and the mold can be changed from a complex stamping process to a general-purpose roll forming roller mold. Verification has shown that after the improvement of the guide rail process, the material utilization rate of the guide rail has increased from 50%~60% in stamping to over 95% in roll forming.
[0026] The original structural design for adjusting the Y-axis of the car window glass was reduced from multiple parts, such as hinge shaft, hinge nut, rivet nut, mounting bolt and adjusting bolt, to a single adjustment structure. The multi-part, multi-directional hole and shaft fit was simplified to a single-part, single-directional hole and shaft fit, thus improving the Y-axis adjustment accuracy.
[0027] Furthermore, in this embodiment, by eliminating the adjusting bolt at the lower end of the guide rail 201, the guide rail 201 will not move in the Y direction and will not encroach on the cross-sectional space of the anti-collision beam, so that the anti-collision beam has sufficient height space for structural reinforcement. At the same time, it can also save the lower space of the door and provide more possibilities for the lower part of the door design.
[0028] Reference Figure 5 In this embodiment of the application, the connection structure includes: Connecting bolt 203 connects the slider body 2022 and the bracket body 2021.
[0029] By connecting bolts 203, the bracket body 2021 and the slider body 2022 are fixed together, and slide up and down relative to the guide rail 201 together with the slider body 2022.
[0030] Reference Figure 5 In this embodiment of the application, the adjustment structure includes: Adjusting bolt 204, one end of which passes through the slider body 2022 and is screwed to the threaded groove 20211 provided on the bracket body 2021.
[0031] When it is necessary to adjust the Y-axis position of the car window glass, first insert the connecting bolt 203 into the bracket body 2021 but do not tighten it, forming a relative pre-position of the bracket body 2021 and the slider body 2022, so that the adjusting bolt 204 can smoothly extend into the threaded groove 20211; then, by adjusting the depth of the adjusting bolt 204 into the threaded groove 20211, the force applied by the adjusting bolt 204 to the bracket body 2021 is adjusted, thereby causing the bracket body 2021 to tilt, driving the car window glass clamped on the bracket body 2021 to adjust its Y-axis position; after the adjustment is in place, tighten the connecting bolt 203 to fix the position of the car window glass.
[0032] Reference Figure 4 The upper and lower ends of the guide rail 201 are respectively provided with mounting holes 2011 for assembly with the door panel. The upper and lower ends of the guide rail 201 are connected and fixed to the inner panel of the door by screws passing through the mounting holes 2011.
[0033] In this embodiment of the application, by eliminating the complex structure at the upper and lower ends of the guide rail, the cross-section of the guide rail 201 is unified, and the manufacturing process of the guide rail 201 is optimized from the stamping process with complex mold structure and high cost to the roll forming process with simple mold structure, low cost and universality (adaptable to guide rails with multiple curvatures).
[0034] To meet the rigidity requirements of frameless doors, the guide rail 201 in this embodiment has a multi-bending design in its transverse section; when the guide rail is manufactured using a roll forming process, the transverse section width is greater than 70mm and the longitudinal depth is greater than 15mm; the thickness of the guide rail 201 is greater than 1.5mm.
[0035] This application embodiment also provides a frameless car door, in which the above-mentioned window regulator is installed.
[0036] This application also provides a vehicle including the aforementioned frameless door.
[0037] In the embodiments of this application, the vehicle may be, but is not limited to, a pure electric vehicle (PEV / BEV), a hybrid electric vehicle (HEV), a range-extended electric vehicle (REEV), a plug-in hybrid electric vehicle (PHEV), a new energy vehicle, or a gasoline vehicle.
