Description

Technical Field

[0001] This utility model belongs to the field of automotive technology, specifically relating to a bracket for a car window regulator and a car window regulator. Background Technology

[0002] A car window regulator is a device used to control the raising and lowering of car windows. Existing car window regulators mainly consist of a guide rail, a cable, a bracket, and a drive unit. The bracket is equipped with a slider that matches the guide rail. Under the drive of the cable, the slider carries the bracket and slides up and down along the guide rail.

[0003] However, due to the tolerances in the manufacturing process of the guide rail, and the fact that different car models may use guide rails with different curvatures, if the same bracket is used, the slider and the surface of the guide rail cannot make close contact. This situation will cause the bracket to vibrate when sliding on the guide rail, which will affect the stability of the window glass lifting and lowering. Utility Model Content

[0004] The purpose of this invention is to provide a bracket for a car window regulator, which reduces the shaking phenomenon when the bracket slides on the guide rail and improves the stability of the car window regulator.

[0005] The purpose of this utility model is achieved through the following technical solution: a bracket for a car window regulator is provided, comprising: a bracket body and a slider; the bracket body is provided with a slider groove, the slider is installed in the slider groove, and the slider includes an arc-shaped spring piece that contacts the guide rail.

[0006] Preferably, the slider includes a mounting part with a preset angle and an abutting part, and the abutting part is provided with an arc-shaped spring piece.

[0007] Preferably, the mounting part is provided with a snap-fit ​​groove, and the bracket body is provided with a snap-fit ​​platform that mates with the snap-fit ​​groove. The slider is installed on the bracket body by snap-fit.

[0008] Preferably, the sidewall of the arc-shaped spring is provided with a clearance portion.

[0009] Preferably, the height of the arc-shaped spring is 2-4mm.

[0010] Preferably, the slider includes a first slider and a second slider symmetrically mounted at both ends of the slider groove.

[0011] Preferably, the bottom inner wall of the slider groove is provided with a compression pad slot, which is located directly below the arc-shaped spring piece; it also includes a compression pad, which is installed in the compression pad slot.

[0012] Preferably, it also includes a buffer pad, the bracket body is provided with a mounting groove that matches the shape of the buffer pad, the bracket body is provided with a first impact part, and the two ends of the buffer pad extend to the outside of the first impact part.

[0013] Due to the adoption of the above technical solution, this utility model has the following advantages:

[0014] The slider is equipped with an arc-shaped spring. The arc-shaped contact reduces the contact area between the slider and the guide rail during movement, reducing resistance and effectively reducing jamming or abnormal noise. The arc-shaped spring is elastic, allowing the bracket body to meet the contact requirements with guide rails of different curvatures. Furthermore, the arc-shaped spring contacts and presses against the guide rail, preventing the bracket body from vibrating in the pressing direction, achieving a damping effect. This effectively prevents the bracket from shaking when sliding along the guide rail, improving the stability of the bracket body sliding along the guide rail.

[0015] Another objective of this invention is to provide a vehicle window regulator that reduces vibration when the bracket body slides along the guide rail, thereby improving the stability of driving the window to rise and fall.

[0016] Another objective of this utility model is achieved through such a technical solution, specifically providing a car window regulator, including a bracket, a guide rail, a support, a drive assembly, and a cable. The support is fixedly installed at both ends of the guide rail, the bracket is slidably installed on the guide rail, the drive assembly and the guide rail are installed on the inner panel of the car door, one end of the cable is connected to the drive assembly, and the other end is connected to the bracket via the support.

[0017] Preferably, the bracket is provided with a second impact part that collides with the bracket, and the second impact part is L-shaped.

[0018] Due to the adoption of the above technical solution, this utility model has the following advantages:

[0019] The drive source is linked to the bracket to reduce vibration when the bracket body slides along the guide rail, thereby improving the stability of the window regulator in raising and lowering the glass. Attached Figure Description

[0035] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0036] Please see Figure 1 and Figure 4 A bracket for a car window regulator includes: a bracket body 1 and a slider 2; the bracket body 1 is provided with a slider groove 11, and the slider 2 is installed in the slider groove 11. The slider 2 includes an arc-shaped spring piece 21 that contacts a guide rail 3. Specifically, the bracket body 1 is an integrally injection-molded rigid plastic or die-cast alloy structure, and the bracket body 1 is provided with a slider groove 11 that penetrates the body along the length direction of the guide rail 3. The slider 2 is snapped into the slider groove 11. The slider 2 is injection-molded from wear-resistant plastic material, and there are two arc-shaped spring pieces 21, symmetrically arranged in the slider 2.

[0037] In this utility model, the bracket for a car window regulator has a slider 2 that bears the sliding friction of the bracket body 1 on the guide rail 3 during use. The contact surface between the slider 2 and the guide rail 3 is arc-shaped, thereby reducing the contact area between the guide rail 3 and the slider 2 during movement, reducing resistance, and effectively reducing jamming or abnormal noise. The contact surface between the slider 2 and the guide rail 3 is elastic, allowing the bracket body 1 to meet the contact requirements with guide rails 3 of different curvatures. Furthermore, the arc-shaped spring piece 21 contacts and presses against the guide rail 3, preventing the bracket body 1 from vibrating in the pressing direction, achieving a damping effect, effectively preventing the bracket from shaking when sliding along the guide rail 3, and improving the stability of the bracket body 1 sliding along the guide rail 3.

[0038] Further, please refer to Figure 1 The slider 2 includes a mounting part 22 with a preset angle and a contact part, the contact part being provided with an arc-shaped spring piece 21. The mounting part 22 and the contact part are integrally formed. The mounting part 22 has a preset angle, which makes the gap at the entrance larger and plays a guiding role, so that the guide rail 3 can be easily inserted and installed on the slider 2.

[0039] Further, please refer to Figures 1 to 3 The mounting part 22 is provided with a snap-fit ​​groove 24, and the bracket body 1 is provided with a snap-fit ​​platform 12 that mates with the snap-fit ​​groove 24. The slider 2 is installed on the bracket body 1 by snap-fit. Specifically, the bracket body 1 is provided with a positioning groove 13, and one end of the mounting part 22 is provided with a protrusion 221 that mates with the positioning groove 13. The protrusion 221 is positioned in the positioning groove 13, restricting the slider 2 from moving in the X and Y directions. The other end of the mounting part 22 is provided with multiple protrusions 222, which together form the snap-fit ​​groove 24. One end of the slider groove 11 extends horizontally towards the slider groove 11, forming the snap-fit ​​platform 12. The snap-fit ​​platform 12 engages with the snap-fit ​​groove 24, restricting the slider 2 from moving in the X, Y, and Z directions. The X direction is along the width of the snap-fit ​​groove 24, the Z direction is along the length of the snap-fit ​​groove 24, and the Y direction is perpendicular to the bottom inner wall of the snap-fit ​​groove 24. Thus, the slider 2 is fixedly snap-fitted onto the bracket body 1.

[0040] Further, please refer to Figure 3 The height h of the curved spring piece 21 is 2-4 mm. Under the specified material, width, and thickness of the curved spring piece 21, if the height h is greater than 4 mm, the bending strength of the curved spring piece 21 is low; while if it is less than 2 mm, the deformation is small, which cannot meet the requirements of guide rails 3 with various curvatures. The width of the curved spring piece 21 is generally slightly larger than the contact surface with the guide rail 3.

[0041] Further, please refer to Figure 5The slider 2 includes a first slider 25 and a second slider 26 symmetrically installed at both ends of the slider groove 11. Specifically, the slider 2 can be integrally formed to increase its strength; or the slider 2 can be divided into a first slider 25 and a second slider 26 with the same structure, which not only simplifies the part structure but also makes it easier to install the slider 2 in the slider groove 11, thus improving production efficiency.

[0042] Further, please refer to Figure 2 The side wall of the arc-shaped spring piece 21 is provided with a clearance part 211. Specifically, an arc-shaped clearance groove is provided on one side of the arc-shaped spring piece 21 along its length direction. When the bracket body 1 is installed, it is flipped laterally onto the sliding surface of the guide rail 3 to avoid the slider 2 being damaged by the sharp edge of the guide rail 3 when the bracket body 1 is flipped.

[0043] Further, please refer to Figure 1 The bottom inner wall of the slider groove 11 is provided with a compression pad slot 111, which is located directly below the arc-shaped spring piece 21. It also includes a compression pad 8, which is installed in the compression pad slot 111. Specifically, the compression pad 8 has two layers, with its outer diameter larger than the inner diameter of the compression pad slot 111. The compression pad 8 is fitted into the wall of the compression pad slot 111, with one layer inside the slider groove 11 and the other outside. Alternatively, the compression pad 8 can be injected into the compression pad slot 111 through secondary injection molding. This structure effectively prevents the compression pad 8 from being squeezed out and falling off after prolonged use. When the arc-shaped spring piece 21 is subjected to abnormal pressure, the compression pad 8 effectively reduces the deformation of the arc-shaped spring piece 21, ensuring that the spring piece does not cause the bracket to wobble on the guide rail due to plastic deformation, and preventing the glass from hitting the rubber strip when closing the door, thus preventing vibration from being transmitted to the bracket and causing abnormal noise when closing the door, thereby reducing vibration.

[0044] Further, please refer to Figure 1 and Figure 5 The system also includes a buffer pad 4. The bracket body 1 has a mounting groove 14 that matches the shape of the buffer pad 4. The bracket body 1 has a first impact part 15, and both ends of the buffer pad 4 extend to the outside of the first impact part 15. Specifically, the buffer pad 4 includes a mounting part 41 and a buffer part 42. The bracket body 1 has a mounting groove 14 that matches the shape of the mounting part 41. The mounting part 41 is fitted into the mounting groove 14, making it less likely for the buffer pad 4 to fall off during use. The buffer part 41 is located outside the first impact part 15 of the bracket body 1. The buffer part 42 has a cavity 421 with a rounded top, which helps the buffer pad 4 release deformation after being subjected to external force, thus playing a buffering role and preventing the bracket body 1 from colliding and being damaged by other objects.

[0045] Please see Figure 6This utility model also provides a car window regulator, including a bracket, a guide rail 3, a support 5, a drive assembly 6, and a cable 7. The support 5 is fixedly installed at both ends of the guide rail 3, and the bracket is slidably installed on the guide rail 3. The drive assembly 6 and the guide rail 3 are installed on the inner panel of the car door. One end of the cable 7 is connected to the drive assembly 6, and the other end is connected to the bracket via the support 5. Specifically, the guide rail 3 has two sets, namely a first guide rail 31 and a second guide rail 32. The support 5 has four sets, namely a first support 51, a second support 52, a third support 53, and a fourth support 54. The first support 51 and the second support 52 are installed at both ends of the first guide rail 31, and the third support 53 and the fourth support 54 are respectively installed at both ends of the second guide rail 32. The bracket has two sets, namely a first bracket and a second bracket. The first bracket is installed in the first guide rail 31, and the second bracket is installed in the second guide rail 32. The cable 7 includes a first cable 71, a second cable 72, and a third cable 73. The drive assembly 6 operates using existing technology, and its principle is consistent with that of the dual-track functional window regulator structure (authorized announcement number CN220909469U). The drive assembly 6 includes a coil base 61 and a drive source 62. The coil base 61 is mounted on the inner panel of the door, and the drive source 62 is mounted inside the coil base 61. One end of the first cable 71 is connected to the coil base 61, and the other end passes around the third bracket 53 and connects to the second bracket. One end of the second cable 72 is connected to the coil base 61, and the other end passes around the second bracket 52 and connects to the first bracket. One end of the third cable 73 passes around the first bracket 51 and connects to the first bracket, and the other end passes around the fourth bracket 54 and connects to the second bracket. The drive source 62 is linked to the first and second brackets via the cables 7. Preferably, the drive source 62 is a motor.

[0046] Further, please refer to Figure 1 and Figure 4 The bracket 5 is provided with a second impact part 55 that collides with the bracket, and the second impact part 55 is L-shaped. Specifically, the first impact part 15 and the second impact part 55 are provided correspondingly. The first impact part 15 is provided with a buffer pad 4. When the bracket runs to the uppermost or lowermost limit position of the guide rail 3, it will not rigidly collide with the bracket 5, thereby reducing the impact noise and damage between the bracket and the bracket 5, and extending the service life of the bracket 5 and the bracket.

[0047] This utility model discloses a bracket and a window regulator for a vehicle window. During use, the slider 2 is equipped with an arc-shaped spring piece 21, which reduces the contact area between the slider 2 and the guide rail 3 during movement, lowering resistance and effectively reducing jamming or abnormal noise. The arc-shaped spring piece 21 is elastic, ensuring that the bracket body 1 can meet the contact requirements with guide rails 3 of different curvatures. Furthermore, the arc-shaped spring piece 21 contacts and presses against the guide rail 3, preventing the bracket body 1 from vibrating in the pressing direction, achieving a damping effect and effectively preventing shaking when the bracket slides along the guide rail 3, thus improving the stability of the bracket body 1 sliding along the guide rail 3. The slider 2 is snap-fitted onto the bracket body 1, restricting its movement in the X, Y, and Z directions, preventing it from falling off even during sliding. The slider 2 includes a first slider 25 and a second slider 26 symmetrically installed at both ends of the slider groove 11, simplifying the component structure and facilitating the installation of the slider 2 in the slider groove 11, thereby improving production efficiency. A compression pad 8 is provided below the curved spring piece 21 to effectively reduce the deformation of the curved spring piece 21 and ensure that the spring piece will not cause the bracket to shake on the guide rail due to plastic deformation. A buffer pad 4 is provided in the first impact part 15 to prevent the bracket body 1 from being damaged by collision with other objects.
