Description

Technical Field

[0001] This utility model relates to the field of automotive electronic control technology, specifically to a window regulator assembly. Background Technology

[0002] The power window assembly is a crucial component of automotive door and window systems, primarily consisting of a motor, reduction gear, guide rails, brackets, and control switches. The motor, as the power source, converts electrical energy into mechanical energy through the reduction gear, driving the window glass to move smoothly up and down along the guide rails. The guide rails and brackets provide precise guidance and support for the glass, ensuring its stability during operation. The control switches allow the driver or passengers to conveniently operate the window, enhancing the passenger experience. The design of the power window assembly must balance safety, reliability, noise control, and harmony with the overall vehicle design, making it an indispensable part of modern automobiles.

[0003] Publication number CN103147655B discloses a rack and pinion type window regulator, including a rack and pinion slide rail fixing plate and a lifting plate. A slide groove is provided on the rack and pinion slide rail fixing plate, and a buckle is provided on the lifting plate. The buckle includes a protrusion and stops on both sides of the protrusion. The protrusion is slidably disposed in the slide groove, and the stops abut against the side walls of the slide groove. A spring is disposed in the slide groove, one end of which is fixed to the upper surface of the slide groove, and a stop is fixed to the other end of the spring. A rack is disposed on one side of the rack and pinion slide rail fixing plate, and a gear is provided on the lifting plate that meshes with the rack. Driven by a motor, when the lifting plate slides along the slide groove, the protrusion abuts against the baffle, causing the spring to deform under force. This technology requires little installation space and is easy to install. It uses a single rack and pinion and a single gear for transmission. Currently, cars on the market use multi-layer glass for sound insulation. Multi-layer glass is heavy. During the glass lifting process, the single rack and pinion transmission structure is prone to tilting and swaying due to the force on one side. At the same time, the wear of the rack and pinion on one side is more concentrated, which will lead to a decrease in transmission efficiency and may even cause jamming and other malfunctions, thus shortening the service life of the lifter. Therefore, this technology still has some room for improvement. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a window regulator assembly that addresses the shortcomings of the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a glass lifter assembly, including a rack and pinion slide rail fixing plate, wherein the rack and pinion slide rail fixing plate is provided with a slide groove for sliding connection of a lifting plate, characterized in that: racks are symmetrically arranged on the inner wall of the slide groove on the rack and pinion slide rail fixing plate; a gear shaft for mounting a driven gear is provided on the side of the lifting plate facing the slide groove; the driven gear is placed in the slide groove and meshes with the rack on any side of the fixing plate; a drive assembly is fixedly installed on the side of the fixing plate away from the gear shaft; the drive assembly passes through the lifting plate and is provided with a drive gear in the slide groove; the drive gear meshes with the driven gear and meshes with the rack on the side away from the driven gear; the drive assembly can drive the lifting plate to move axially back and forth by driving the drive gear and the driven gear.

[0006] With the above technical solution, racks are symmetrically arranged on the inner wall of the groove of the rack and pinion rail fixing plate. The driven gear on the lifting plate and the driving gear of the drive component form a double gear transmission structure. The drive component drives the driving gear and the driven gear to move the lifting plate axially back and forth. This allows the lifting plate to be evenly stressed during the glass lifting process, which greatly improves the stability of the glass lifting and avoids the problem of glass tilting and shaking caused by unilateral stress. This ensures a smooth and stable lifting process. At the same time, the double rack and pinion transmission structure can distribute the weight of the glass to the racks on both sides, which can accommodate larger, thicker and heavier glass and meet the diverse needs of different vehicle models.

[0007] The aforementioned window regulator assembly can be further configured such that: the drive component includes a drive motor fixedly installed on the side of the lifting plate away from the gear shaft; one side of the drive motor is provided with a connection terminal for connecting to the vehicle; the drive motor includes a motor body and a vertical rotating shaft; the end of the vertical rotating shaft is provided with a horizontal rotating disk that changes the direction of the vertical rotating shaft; the horizontal rotating disk is fixedly installed on the side of the lifting plate away from the gear shaft; the vertical rotating shaft can drive the horizontal rotating disk to rotate; and the center of the horizontal rotating disk and located in a groove is provided with a drive gear shaft connected to the drive gear.

[0008] With the above technical solution, the drive motor is fixedly installed on the side of the lifting plate away from the gear shaft, making the structure of the entire window regulator assembly more compact and easy to install in the limited space of the car. The horizontal rotating disk at the end of the vertical rotating shaft can convert the vertical rotation of the motor into horizontal rotation, so that the center of the horizontal rotating disk is located in the slide groove and the drive gear connected to the drive gear can be rotated by the motor body.

[0009] The aforementioned glass lifter assembly can be further configured such that: the lifting plate includes a connecting plate slidably connected to the rack and pinion rail fixing plate and a glass bracket disposed on one side of the connecting plate, wherein the glass bracket is provided with glass clamping structures for clamping glass at both ends.

[0010] Using the above technical solution, the connecting plate slides smoothly in the groove of the rack and pinion slide rail fixing plate, providing stable guidance and support for the lifting and lowering of the glass; the glass bracket is specifically used to install and fix the glass, so that the glass can achieve the lifting and lowering function as the lifting plate moves.

[0011] The aforementioned glass regulator assembly can be further configured such that: the glass clamping structure includes mounting grooves disposed at both ends of the glass bracket, the mounting grooves being symmetrically disposed on both sides of the glass bracket end, a clamping plate being fixedly installed in the mounting groove, and a clamping groove for clamping the car glass being formed between the clamping plates, and a soft rubber part being provided at the end of the clamping plate to increase friction and prevent scratching of the car glass during clamping.

[0012] Using the above technical solution, the glass bracket is provided with mounting grooves at both ends, which are symmetrically distributed on both sides of the ends to ensure the symmetry and balance of the clamping structure. The clamping plate fixedly installed in the mounting groove forms a clamping groove for clamping the car glass, which can firmly clamp the glass and ensure that the glass will not shake or shift during the lifting process. The soft rubber part provided at the end of the clamping plate increases the friction between the glass and the car glass, further enhancing the clamping firmness and making the glass more stable and reliable during the lifting process. At the same time, the soft rubber part can prevent the glass surface from being scratched when clamping the car glass.

[0013] The aforementioned glass lifter assembly can be further configured such that: the rack and pinion rail fixing plate has limit grooves at both ends, and the connecting plate has a first limit protrusion on the side facing the rack and pinion rail fixing plate, the first limit protrusion abutting against the limit groove.

[0014] By adopting the above technical solution, limiting grooves are opened at both ends of the rack slide rail fixing plate, and a first limiting protrusion is set on the side of the connecting plate facing the rack slide rail fixing plate. The two cooperate with each other to abut against each other, which can effectively limit the sliding range of the connecting plate.

[0015] The aforementioned glass lifter assembly can be further configured such that: a stop is provided on the side of the connecting plate away from the glass bracket, and a buffer component is provided at the end of the rack and pinion slide rail fixing plate to buffer the lifting plate when it descends by contacting the stop.

[0016] By adopting the above technical solution, a stop is installed on the side of the connecting plate away from the glass bracket, and a buffer component is equipped at the end of the rack and pinion slide rail fixing plate. The two work together to effectively buffer the impact force when the lifting plate descends. When the lifting plate descends to the end of the rack and pinion slide rail fixing plate, the stop will abut against the buffer component, avoiding damage to components that may be caused by hard contact, reducing wear and tear on various components caused by impact, and greatly extending the service life of the window regulator assembly.

[0017] The aforementioned glass lifter assembly can be further configured such that: the buffer component includes an arc-shaped mounting groove disposed at the end of the rack and pinion slide rail fixing plate, a buffer bracket is axially disposed in the arc-shaped mounting groove, a buffer rubber is disposed on the side of the buffer bracket facing the stop block, and an axial adjustment structure is also provided between the buffer bracket and the buffer rubber.

[0018] Using the above technical solution, the arc-shaped mounting groove provides installation space for the buffer bracket. The buffer rubber is set on the side of the buffer bracket facing the stop. When the lifting plate descends and the stop comes into contact with the buffer rubber, the buffer rubber can effectively absorb and disperse the impact force, avoid the stop from directly and rigidly colliding with the rack and pinion rail fixing plate, reduce the noise and vibration caused by the impact, and greatly extend the service life of the window lifter.

[0019] The aforementioned glass lifter assembly can be further configured such that: the axial adjustment structure includes an adjustment groove opened in the buffer bracket; the buffer rubber includes a buffer end that abuts against the stop block and a connecting end placed in the adjustment groove; the connecting end has second abutment protrusions on both sides to limit the axial position; the arc-shaped mounting groove has an adjustment hole; the adjustment hole has an adjustment screw; the adjustment screw has an adjustment plate on the side facing the connecting end; and the adjustment plate abuts against the side wall of the adjustment screw.

[0020] Using the above technical solution, the adjustment groove of the buffer bracket and the connection end of the buffer rubber provide adjustment space for the installation and axial adjustment of the buffer rubber. The second abutment protrusions on both sides of the connection end can effectively limit the axial position of the buffer rubber, ensuring that it will not shift during adjustment and ensuring the stability and accuracy of the buffering effect. By rotating the adjustment screw, the adjustment plate will move accordingly, thereby pushing the buffer rubber to move axially within the adjustment groove. This adjustment method can fine-tune the position of the buffer rubber according to different vehicle models, different glass weights, and different impact forces generated in actual use, in order to achieve the best buffering effect.

[0021] The aforementioned glass lifter assembly can be further configured such that: the horizontal rotating disk is provided with a plurality of connecting ears, both the connecting ears and the connecting plate are provided with fixing holes, and the surface of the connecting plate is provided with a through hole for the drive gear shaft to pass through.

[0022] By adopting the above technical solution, the connecting ears of the horizontal rotating disk cooperate with the fixing holes on the connecting plate to achieve a stable connection between the horizontal rotating disk and the connecting plate. The through hole through which the drive gear shaft passes provides an accurate installation position and a smooth transmission path for the drive gear shaft.

[0023] The beneficial effects of this utility model are as follows: racks are symmetrically arranged on the inner wall of the groove of the rack and pinion slide rail fixing plate, and the driven gear on the lifting plate and the driving gear of the drive component form a double gear transmission structure, which greatly improves the stability of glass lifting and avoids the problem of glass tilting and shaking caused by unilateral force, and ensures the smooth and stable lifting process.

To ensure the glass does not shake or shift during lifting, the soft rubber part 18 at the end of the clamping plate 16 increases the friction between the clamping plate and the car glass, further enhancing the clamping firmness and making the glass more stable and reliable during lifting. Simultaneously, the soft rubber part 18 prevents scratching the glass surface when clamping the car glass. Limit grooves 19 are provided at both ends of the rack and pinion slide rail fixing plate 1.
