Utility Model Content

[0005] The purpose of this utility model is to provide a sliding mechanism for a window regulator, which solves the problem that in the aforementioned device, the car window glass is fixed on the main guide rail with screws, but after a long period of use, the screws are prone to loosening, causing the car window glass to loosen on the main guide rail, producing abnormal noise, and even affecting the stability of the car window glass lifting.

[0006] To achieve the above objectives, this utility model provides a sliding mechanism for a glass lifter, including a support frame and a side plate. The side plate is fixedly installed on the support frame. It also includes a clamping device, which includes a sliding plate, a clamping arc plate, a mounting shaft, an elastic guide assembly, and a transmission assembly. A through groove is provided on one side of the support frame. The sliding plate is slidably installed on the support frame through the elastic guide assembly. The mounting shaft is rotatably installed on the side plate through the transmission assembly. The clamping arc plate is fixedly installed on the mounting shaft and close to the sliding plate.

[0007] The elastic guide assembly includes a support spring and a guide rod. The guide rod is fixedly installed on the sliding plate and slides in cooperation with the support frame.

[0010] The support frame is also provided with an installation frame and sound-absorbing cotton. The installation frame is fixedly installed on the support frame and located on the side of the support frame away from the sliding plate; the sound-absorbing cotton is fixedly installed inside the installation frame.

[0011] This utility model discloses a sliding mechanism for a window regulator. When installing a car window, the window is placed on a sliding plate. Under the weight of the window, the sliding plate drives the guide rod to slide down along the support frame, compressing the support spring. As the sliding plate slides down, the transmission rack moves downward. The transmission rack meshes with the transmission gear, causing the transmission gear to rotate in the opposite direction to the sliding plate. The transmission gear drives the mounting shaft to rotate, which in turn drives the clamping arc plate to rotate towards the window until the clamping arc plate clamps the window, thus fixing the window. The window can be raised or lowered by driving the support frame up and down through an external lifting mechanism. Thus, under the weight of the window, the movement of the sliding plate, transmitted through the transmission assembly, drives the clamping arc plate on the mounting shaft to clamp and fix the window, maintaining its stability on the support frame.

Detailed Implementation

[0017] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0018] The embodiment of this application is as follows:

[0019] Please see Figure 1-3 , Figure 1 This is a schematic diagram of the overall structure of the sliding mechanism of a window regulator according to this utility model. Figure 2 This is a schematic diagram of the clamping device of this utility model. Figure 3 This is a schematic diagram of the transmission component of this utility model.

[0020] This utility model provides a sliding mechanism for a window regulator: it includes a support frame 101 and a side plate 102, and also includes a clamping device. The clamping device includes a sliding plate 103, a clamping arc plate 105, a mounting shaft 106, an elastic guide assembly, and a transmission assembly. The elastic guide assembly includes a support spring 108 and a guide rod 109. The transmission assembly includes a transmission rack 110 and a transmission gear 111. The clamping arc plate 105 is also provided with a first clamping pad 112 and a second clamping pad 113. The support frame 101 is also provided with a mounting frame 114 and sound-absorbing cotton 115. The aforementioned solution solves the problem that the car window glass of the aforementioned device is fixed on the main guide rail with screws, but after long-term use, the screws are prone to loosening, causing the car window glass to loosen on the main guide rail, producing abnormal noise, and even affecting the stability of the car window glass lifting. The aforementioned solution can be used in the scenario of installing glass in a window regulator.

[0021] In this embodiment, the movement of the sliding plate 103 is caused by the weight of the window glass, which is transmitted through the transmission component, thereby driving the clamping arc plate 105 on the mounting shaft 106 to clamp and fix the window glass, thus maintaining the stability of the window glass on the support frame 101.

[0022] The support bracket 101 has a through groove 107 on one side. The sliding plate 103 is slidably mounted on the support bracket 101 via the elastic guide assembly. The mounting shaft 106 is rotatably mounted on the side plate 102 via the transmission assembly. The clamping arc plate 105 is fixedly mounted on the mounting shaft 106 and close to the sliding plate 103. The support bracket 101 has an L-shaped structure. The side plates 102 are fixed to both sides of the support bracket 101 with screws. The sliding plate 103 is located between the two side plates 102. The clamping arc plate 105... 05 has an arc-shaped structure. The mounting shaft 106 is set on the side plates 102 on both sides. The elastic guide component and the transmission component are both set on the bottom sides of the sliding plate 103. The sliding plate 103 is used to place the window glass. Under the weight of the window glass, the sliding plate 103 is lowered by the elastic guide component. The transmission component drives the mounting shaft 106 to rotate by the movement of the sliding plate 103, so that the clamping arc plate 105 clamps and fixes the window glass, keeping the window glass stable on the support bracket 101.

[0023] Secondly, the guide rod 109 is fixedly installed on the sliding plate 103 and slides in cooperation with the support frame 101; the support spring 108 is sleeved on the guide rod 109, and the two ends of the support spring 108 are fixedly connected to the support frame 101 and the sliding plate 103 respectively. The guide rod 109 is welded to the bottom of the sliding plate 103, and the axis of the support spring 108 coincides with that of the guide rod 109. Through the setting of the support spring 108, the sliding plate 103 can be guaranteed to be in the initial position above the support frame 101. Through the setting of the guide rod 109, the guiding function of the sliding plate 103 can be realized.

[0024] Furthermore, the transmission rack 110 is fixedly mounted on the sliding plate 103 and passes through the through groove 107; the transmission gear 111 is fixedly mounted on the mounting shaft 106 and meshes with the transmission rack 110. The transmission rack 110 is welded to the bottom of the sliding plate 103. The transmission gear 111 is a spur gear. Through the meshing transmission of the transmission rack 110 and the transmission gear 111, the movement of the sliding plate 103 can be converted into the rotation of the mounting shaft 106.

[0025] Furthermore, the first clamping pad 112 is fixedly installed on the clamping arc plate 105; the second clamping pad 113 is fixedly installed on the clamping arc plate 105 and located on the side of the clamping arc plate 105 close to the first clamping pad 112. The first clamping pad 112 and the second clamping pad 113 are respectively disposed on both sides of the top of the clamping arc plate 105. Both the first clamping pad 112 and the second clamping pad 113 are made of rubber. Through the cooperation of the first clamping pad 112 and the second clamping pad 113, the clamping force of the clamping arc plate 105 on the vehicle window glass is enhanced.

[0026] Finally, the mounting frame 114 is fixedly mounted on the support bracket 101 and located on the side of the support bracket 101 away from the sliding plate 103; the sound-absorbing cotton 115 is fixedly mounted inside the mounting frame 114, the mounting frame 114 is fixed to the support bracket 101 by screws, and the sound-absorbing cotton 115 is glued inside the mounting frame 114, thereby achieving a sound-absorbing effect when the car window glass is raised and lowered.

[0027] In this embodiment, when installing the vehicle window glass, the window glass is placed on the sliding plate 103. Under the weight of the window glass, the sliding plate 103 drives the guide rod 109 to slide down along the support frame 101, causing the support spring 108 to compress. As the sliding plate 103 slides down, the transmission rack 110 moves downward. The transmission rack 110 meshes with the transmission gear 111, causing the transmission gear 111 to rotate in the opposite direction to the sliding plate 103. The transmission gear 111 drives the mounting shaft 106 to rotate. The mounting shaft 106 further drives the clamping arc plate 105 to rotate towards the window glass until the clamping arc plate 105 clamps the window glass, thus fixing the window glass. The support frame 101 can be moved up and down by an external lifting mechanism to realize the lifting and lowering of the window glass. Under the weight of the window glass, the movement of the sliding plate 103 is transmitted through the transmission component, which drives the clamping arc plate 105 on the mounting shaft 106 to clamp and fix the window glass, maintaining the stability of the window glass on the support frame 101.

[0028] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
