Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive window lifting technology, specifically to an automotive window lifting limit mechanism. Background Technology
[0002] Automotive window regulators, also known as window lifters, are devices that control the raising and lowering of automotive door and window glass. They are mainly divided into manual window regulators and electric window regulators. The main lifting methods of window regulators are parallel arm lifting and cross arm lifting. The lower rail in the cross arm can effectively support and limit the raising and lowering of the glass.
[0003] The aforementioned device lacks a structure for adjusting the tilt angle of the car window during use. This causes the existing crossarm type car window lifter to develop a certain amount of play between the crossarm and other components after prolonged use. As a result, the car window may tilt forward or backward during the lifting process, making it impossible to close the window completely. Based on the shortcomings of the existing technology, this utility model designs a car window lifting limit mechanism. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an automotive window lifting and limiting mechanism that has the advantage of adjusting the tilt angle of automotive windows.
[0005] This utility model provides the following technical solution: an automotive window lifting and limiting mechanism, including a rotating frame, characterized in that: a cross main arm is rotatably arranged on one side of the rotating frame, a cross secondary arm is rotatably arranged on the cross main arm, and an adjustment mechanism is provided at the bottom end of the cross secondary arm to facilitate limiting and adjusting the lifting of the rotating frame; The adjustment mechanism includes a slide rail, a back plate, an adjustment frame, a mounting hole, an adjustment slider, and a fastening bolt. The slide rail is slidably connected to the bottom end of the cross arm, the back plate is fixedly connected to both ends of the slide rail, the adjustment frame is slidably disposed on the inner side of the back plate, the mounting hole is opened through the adjustment frame, the two adjustment sliders are slidably connected inside the adjustment frame, and the fastening bolt is threadedly connected to the adjustment slider.
[0006] As a preferred embodiment of this utility model, a transmission gear is rotatably provided on the rotating frame, a throttle is fixedly installed on the transmission gear, a driven gear is rotatably connected to the rotating frame, and a coil spring is provided between the rotating frame and the driven gear.
[0007] As a preferred technical solution of this utility model, the top ends of the cross main arm and the cross auxiliary arm are slidably connected to a lifting frame, and the two ends of the lifting frame are fixedly connected to bracket buckles.
[0008] As a preferred embodiment of this utility model, the fastening bolt is threaded through the back plate and connected to the adjusting slider.
[0009] As a preferred embodiment of this utility model, the back plate and the adjusting slider are clamped and mounted on the adjusting frame.
[0010] As a preferred technical solution of this utility model, the top ends of the cross main arm and the cross auxiliary arm are provided with pulleys, and the top pulleys of the cross main arm and the cross auxiliary arm are slidably connected to the inner side of the lifting frame.
[0011] As a preferred embodiment of this utility model, the bottom end of the cross arm is provided with a pulley, and the pulley at the bottom end of the cross arm is slidably connected in the slide rail.
[0012] As a preferred technical solution of this utility model, the driven gear disk is fixedly connected to the bottom end of the cross main arm, and the driven gear disk meshes with the transmission gear for transmission.
[0013] Compared with the prior art, the present invention has the following beneficial effects: This automotive window lifting and limiting mechanism loosens four fastening bolts at both ends of the slide rail, disengaging the back plate and adjusting slider from the clamping and fixing of the adjusting frame, allowing the slide rail and adjusting frame to slide and adjust. If the car window deviates forward during lifting, the slide rail needs to be moved downward in a straight line a certain distance under the limiting of the adjusting frame and adjusting slider to lower the bottom fulcrum of the cross arm. After adjustment, tightening the fastening bolts will clamp and limit the back plate and adjusting slider to fix the slide rail and adjusting frame. If the car window deviates backward during lifting, the adjusting slide rail only needs to be moved upward. This device facilitates the adjustment of the deviation of the car window during lifting.

A transmission gear 101 rotatably mounts on the rotating frame 1, and a throttle 102 is fixedly mounted on the transmission gear 101. A driven gear 103 is rotatably connected to the rotating frame 1. A coil spring 104 is provided between the rotating frame 1 and the driven gear 103. The driven gear 103 is fixedly connected to the bottom end of the cross main arm 2, and the driven gear 103 meshes with the transmission gear 101 for transmission.
[0018] Please see Figure 3 The top ends of the cross main boom 2 and the cross auxiliary boom 201 are slidably connected to the lifting frame 202. The two ends of the lifting frame 202 are fixedly connected to the bracket buckle 203. The top ends of the cross main boom 2 and the cross auxiliary boom 201 are provided with pulleys, and the top pulleys of the cross main boom 2 and the cross auxiliary boom 201 are slidably connected to the inner side of the lifting frame 202. The bottom end of the cross auxiliary boom 201 is provided with pulleys, and the bottom pulleys of the cross auxiliary boom 201 are slidably connected to the slide rail 301.
[0019] Please see Figure 4-5The adjustment mechanism 3 includes a slide rail 301, a back plate 302, an adjustment frame 303, a mounting hole 304, an adjustment slider 305, and a fastening bolt 306. The slide rail 301 is slidably connected to the bottom end of the cross arm 201. The back plate 302 is fixedly connected to both ends of the slide rail 301. The adjustment frame 303 is slidably disposed on the inner side of the back plate 302. The mounting hole 304 is opened through the adjustment frame 303. Two adjustment sliders 305 are slidably connected inside the adjustment frame 303. The fastening bolt 306 is threadedly connected to the adjustment slider 305. The fastening bolt 306 passes through the back plate 302 and is threadedly connected to the adjustment slider 305. The back plate 302 and the adjustment slider 305 are clamped and disposed on the adjustment frame 303.
[0020] By setting the slide rail 301, support is provided to the bottom end of the cross arm 201, allowing the cross main arm 2 and the cross arm 201 to raise, lower, and limit the vehicle window. By setting the adjustment bracket 303 and the adjustment slider 305, the slide rail 301 can be adjusted to move linearly up and down. When the vehicle window moves up and tilts forward, the slide rail 301 is adjusted downward; when the vehicle window moves down, the slide rail 301 is adjusted upward. By setting the back plate 302 and the fastening bolt 306, the slide rail 301 is limited after adjustment.
[0021] Working principle: When a car window lifting and limiting mechanism is used, in the initial state, the transmission gear 101 and the throttle 102 first rotate on one side of the rotating frame 1. The driven gear 103, which is rotatably connected to the rotating frame 1, meshes with the transmission gear 101 and is connected to the cross main arm 2 and the cross secondary arm 201. The top of the cross main arm 2 and the cross secondary arm 201 is equipped with a lifting frame 202 and a bracket buckle 203, so that after rotating the throttle 102, the lifting frame 202, the bracket buckle 203 and the car window can be lifted and lowered through the transmission. The slide rail 301 connected to the bottom of the cross secondary arm 201 is connected to the back plate 302 at both ends. The fastening bolt 306 that is installed through the back plate 302 is connected to the adjusting slider 305 that is slidably connected in the adjusting frame 303, so as to adjust the installation position of the slide rail 301. When adjusting the deviation of the car window during the raising and lowering process, first loosen the four fasteners 306 at both ends of the slide rail 301 one by one, so that the back plate 302 and the adjusting slider 305 are disengaged from the clamping and fixing of the adjusting frame 303, and the slide rail 301 and the adjusting frame 303 can be slidably adjusted. If the car window deviates forward during the raising process, the slide rail 301 needs to be moved downward in a straight line a certain distance under the limit of the adjusting frame 303 and the adjusting slider 305 so that the bottom fulcrum of the cross arm 201 is lowered. After the adjustment is completed, tighten the fasteners 306 so that the back plate 302 and the adjusting slider 305 clamp and limit the slide rail 301 and the adjusting frame 303. If the car window deviates backward during the raising and lowering process, simply move the adjusting slide rail 301 upward. This device is convenient for adjusting the deviation of the car window during the raising and lowering process.
