Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a window glass guide rail. Background Technology

[0002] Window rails are a crucial component of car window regulators. Window rails include, for example,... Figure 1 The guide rail bracket 01 and sealing strip (not shown in the figure) are shown. The sealing strip is directly embedded in the guide rail bracket 01 and fits against the rib 012 at the groove opening of the guide rail groove 011 on the guide rail bracket 01. During the raising and lowering of the car window, the sealing strip is damaged by friction, which can lead to malfunctions such as shaking, abnormal noise, or even failure of the car window to raise and lower. Utility Model Content

[0003] To reduce the likelihood of window lift malfunctions, this invention proposes a window glass guide rail. The guide rail includes a guide rail bracket with a guide rail groove, and the overlapping surface at the groove opening is flat. Compared to existing window glass guide rails, the present invention's guide rail features a flat overlapping surface on the guide rail bracket for attaching the sealing strip, effectively reducing the overlap area between the guide rail bracket and the sealing strip. This reduces the rate of frictional damage to the sealing strip, thereby lowering the probability of window lift malfunctions.

[0004] Preferably, the upper end of the lap surface in the assembled state is provided with a beveled surface, and the beveled surface is formed by chamfering. In this way, the overlap area between the sealing strip and the guide rail bracket during the raising and lowering of the window glass can be further reduced, thereby further reducing the wear of the sealing strip.

[0005] Preferably, the guide rail groove is provided with a plurality of spaced-apart slots, and each slot has a protruding part at its opening, which is located on the inner wall of the guide rail groove. Thus, when the sealing strip and the guide rail bracket are assembled together to form the window glass guide rail of this utility model, the slots and protruding parts on the guide rail bracket can be used to hold the sealing strip in place, reducing the displacement of the sealing strip during the raising and lowering of the window glass, thereby reducing wear on the sealing strip. Furthermore, two protruding parts are provided at the opening of the slot, and these protruding parts are located near the two ends of the slot extending along the guide rail groove. Thus, by using the two protruding parts at both ends of the slot to hold the sealing strip in place, the securing effect of the sealing strip in the guide rail groove can be improved, thereby further reducing wear on the sealing strip.

[0006] Preferably, a hook is provided on the inner wall of the guide rail groove, and the hook faces the overlapping surface. This allows the hook to hold the edge of the sealing strip in place when the sealing strip is embedded in the guide rail groove on the guide rail bracket, thereby improving the sealing strip's fixation within the guide rail groove and reducing wear caused by the raising and lowering of the car window. Furthermore, the hook and the groove are arranged opposite to each other. This further enhances the sealing strip's fixation within the guide rail groove by using the hook in conjunction with the protrusion and groove, further reducing wear on the sealing strip. Attached Figure Description

[0007] Figure 1 A schematic diagram of the guide rail bracket in an existing car window glass guide rail; Figure 2 This is a first-view structural schematic diagram of the guide rail bracket in the vehicle window glass guide rail of this utility model. Figure 3 This is a second-view structural schematic diagram of the guide rail bracket in the vehicle window glass guide rail of this utility model. Detailed Implementation

[0008] Below, in conjunction with Figure 2 and 3 This invention provides a detailed description of the vehicle window glass guide rail.

[0009] like Figure 2 and 3As shown, the vehicle window glass guide rail of this utility model includes a guide rail bracket 1, on which a guide rail groove 11 is provided, and the overlapping surface 111 at the groove opening of the guide rail groove 11 is flat. Thus, compared to existing vehicle window glass guide rails, the overlapping surface of the guide rail bracket 1 for attaching the sealing strip in this utility model is set to flat, effectively reducing the overlapping area between the guide rail bracket 1 and the sealing strip, thereby reducing the rate of frictional damage to the sealing strip and consequently reducing the probability of window glass lifting and lowering malfunctions. Preferably, the upper end of the overlapping surface 111 in the assembled state is provided with a chamfered surface 1111, and this chamfered surface 1111 is formed by a bevel. This further reduces the overlapping area between the sealing strip and the guide rail bracket 1 during the lifting and lowering of the vehicle window, thereby further reducing the wear of the sealing strip. Preferably, the guide rail groove 11 is provided with a plurality of spaced-apart slots 112, and a locking protrusion 113 is provided at the opening of the slot 112, and the locking protrusion 113 is located on the inner wall of the guide rail groove 11. Thus, when the sealing strip and the guide rail bracket 1 are assembled together to form the window glass guide rail of this utility model, the slots 112 and locking protrusions 113 on the guide rail bracket 1 can be used to lock the sealing strip, reducing the displacement of the sealing strip during the raising and lowering of the window glass, thereby reducing the wear of the sealing strip. Furthermore, two locking protrusions 113 are provided at the opening of the slot 112, and the locking protrusions 113 are close to both ends of the slot 112 extending along the guide rail groove 11. Thus, by using the two locking protrusions 113 located at both ends of the slot 112 to lock the sealing strip, the locking effect of the sealing strip in the guide rail groove 11 can be improved, thereby further reducing the wear of the sealing strip. Preferably, a hook 114 is provided on the inner wall of the guide rail groove 11, and the hook 114 faces the overlapping surface 111. In this way, when the sealing strip is embedded in the guide rail groove 11 on the guide rail bracket 1, the hook 114 can be used to hold the edge of the sealing strip, thereby improving the fixing effect of the sealing strip in the guide rail groove 11, and further reducing the wear of the sealing strip caused by the raising and lowering of the vehicle window glass. Furthermore, the hook 114 and the groove 112 are arranged opposite to each other. Thus, by using the hook 114 in conjunction with the protrusion 113 and the groove 112, the fixing effect of the sealing strip in the guide rail groove 11 can be further improved, thereby further reducing the wear of the sealing strip.
