Description

Technical Field

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

[0002] Currently, the main components driving the raising and lowering of car windows include the drive assembly, guide rail, cable, glass bracket, and support. Specifically, the drive assembly is installed on the inner door panel, the support is installed at both ends of the guide rail, the glass bracket is slidably mounted on the guide rail, and the guide rail is secured to the inner door panel by the support. One end of the cable is connected to the drive assembly, and the other end is connected to the bracket after passing through the pulley of the support. Thus, the drive assembly drives the glass bracket to slide along the guide rail via the cable.

[0003] In practical applications, the pull cable consists of a steel wire rope and a cable sleeve. The cable sleeve, from the inside out, is composed of plastic, a spring tube, and a plastic coating layer. When the pull cable moves the glass bracket, if the cable routing is not smooth, the spring tube is prone to twisting or deformation. As the glass bracket moves, it pulls the steel wire rope through the cable sleeve. The deformed spring tube increases friction between the steel wire rope and the innermost plastic layer of the cable sleeve, leading to increased internal resistance of the lifter and reduced operating efficiency. The bracket includes an upper bracket and a lower bracket. Due to the varying window travel and shape of different car models, and the influence of the arrangement of sheet metal parts in the door inner panel such as magnetic locks and limiters, the lower bracket needs to be designed separately to meet the cable routing requirements. The upper bracket is usually installed on the reinforcing plate of the door inner panel. The reinforcing plates of different car models are located below the water-cutting edge and are relatively close in position, so the upper bracket installation structure is relatively simple. The installation position of the drive component varies slightly between different car models. The smoothness of the cable routing is determined by both the cable's exit position from the bracket and the installation position of the drive component.

[0004] In the existing technology, the solution to this problem is to develop a dedicated upper bracket for each vehicle model and adjust the exit position of the cable from the upper bracket to match the installation position of the drive component to ensure smooth cable routing. However, developing a dedicated bracket will significantly increase costs. Utility Model Content

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

[0036] Please see Figure 1 , Figure 5 and Figure 6 An upper bracket for a vehicle window regulator includes a bracket body 1 and a clamping head 2. The bracket body 1 has a cable entry end 11 with at least two mounting slots 111. The clamping head 2 can be selectively installed in one of the mounting slots 111, and the cable 4 extends out of the bracket body 1 after passing through the clamping head 2. Specifically, the upper bracket also includes a pulley 3 with a groove, which is rotatably mounted on the bracket body 1. The bracket body 1 has a frustum 13 that matches the shape of the pulley 3, and the frustum 13 has a shaft hole 131 in the middle for mounting the pulley 3. The pulley 3 is riveted to the bracket body 1 by a pin 15. The bracket body 1 has at least two mounting slots 111 facing the drive component, and the mounting slots 111 face the drive component at different angles. The cable 4 includes a steel wire rope 411 and a cable sleeve 412 covering the steel wire rope 411. One end of the cable 4 is installed on the drive assembly of the window regulator. The cable is installed using existing technology, such as the authorized announcement number CN206917493U, entitled "A Window Regulator Roller Seat and Window Regulator with Sleeve Fixing Structure". The other end of the cable 4 is installed on the clamping head 2. After the cable sleeve 412 is installed on the clamping head 2, the steel wire rope 411 is exposed outside the cable sleeve 412 and extends out of the bracket body 1 after winding around the groove of the pulley 3.

[0037] This utility model discloses a bracket structure for a car window regulator. In use, depending on the installation position of the drive component, the clamping head 2 is installed on the bracket body 1 by selecting a suitable mounting slot 111 according to the installation position of the drive component. The wiring angle meets the working requirements, so the same bracket can be used for multiple car models, reducing the development cost of the upper bracket.

[0038] Further, please refer to Figure 1 and Figure 2 The clamping head 2 has two symmetrical strip grooves 21 on its outer side, and the mounting groove 111 extends to the outer edge of the bracket body 1 with a protruding edge 16 that mates with the strip grooves 21. Specifically, the clamping head 2 is made of wear-resistant plastic, and the strip grooves 21 are arranged along the axial direction of the clamping head 2. The length of the strip grooves 21 is less than the length of the clamping head 2.

[0039] Further, please refer to Figure 2The slot 21 includes a guide portion 211 and a clamping portion 212. The guide portion 211 gradually decreases in size from the port to the clamping portion 212, and the width of the clamping portion 212 is less than the thickness of the protruding edge 16. With this structure, the port opens outward, the protruding edge 16 is easily inserted and installed in the slot 21, and the width of the clamping portion 212 is slightly less than the thickness of the protruding edge 16. The clamping head 2 is fixed in the protruding edge 16 by interference fit, and the clamping head 2 is not easy to fall off.

[0040] Further, please refer to Figure 3 and Figure 4 The clamping head 2 has a through hole 22 in the middle, and several protruding ribs 221 are arranged circumferentially along the inner wall of the through hole 22. Specifically, the inner diameter of the through hole 22 matches the outer diameter of the cable sleeve 412. The protruding ribs 221 are evenly spaced circumferentially along the inner wall of the through hole 22. The protruding ribs 221 are divided into guide sections 222, clamping sections 223, and releasing sections 224. The thickness of the guide section 222 gradually increases from the end to the clamping section 223, making it easy for the cable 4 to be inserted and installed in the through hole 22. The inner diameter formed by the clamping sections 223 is slightly smaller than the outer diameter of the cable sleeve 412. The deformation of 412 causes the cable 4 to be clamped in the through hole 22. The thickness of the relaxation section 224 gradually decreases from the clamping section 223 to the outlet. The cable sleeve 412 recovers its deformation. Even if the cable 4 is subjected to external force, the cable 4 is not easy to fall off the clamping head 2. At the same time, the wire rope 411 is exposed from the clamping head 2 in the cable sleeve 412. The wire rope 411 will swing under the action of external force. The relaxation section 224 provides swing space, which is conducive to the sliding of the wire rope 411 in the cable sleeve 412.

[0041] Further, please refer to Figure 1 , Figure 5 and Figure 6 There are two mounting slots 111. The area of ​​the bracket body 1 is not significantly increased by providing two mounting slots 111, therefore there is no significant increase in material and mold costs. Preferably, the two mounting slots 111 are arranged side by side, and the central protruding edge 16 can be shared, reducing the area of ​​the bracket body 1.

[0042] Further, please refer to Figure 1 and Figure 6 It also includes a pulley 3 rotatably mounted on the support body 1. A limiting stop 17 is provided on the upper end of the support body 1 near the pulley 3. The distance d between the limiting stop 17 and the pulley 3 is less than the outer diameter of the cable 4. Specifically, the limiting stop 17 extends upward along the edge of the support body 1 to form the limiting stop 17. The plane of the limiting stop 17 is curved to accommodate the installation space of the pulley 13 and the space of the cable entry end 11. The distance d between the limiting stop 17 near the pulley 3 and the pulley 3 is less than the outer diameter of the cable 4. This structure prevents the wire rope 411, which passes over the pulley 3, from detaching from the pulley 3 when subjected to external force.

[0043] Further, please refer to Figure 1 and Figure 7 It also includes a nut 18 and an adjusting screw 19. The nut 18 has an internal threaded hole 181 that mates with the adjusting screw 19. The upper end of the bracket body 1 has a mounting hole 12 through which the nut 18 passes. The contact surface between the adjusting screw 19 and the inner door panel is a spherical surface 191. The contact surface between the adjusting screw 19 and the inner door panel is a flange surface, which is a spherical surface 191. When the upper and lower end faces of the guide rail 5 are at different heights, it ensures that the spherical surface 191 of the adjusting screw 19 always maintains a tight fit with the inner door panel during assembly. The risk of torque attenuation after tightening the adjusting screw 19 and the nut 18 is controllable.

[0044] Please see Figure 5 This utility model also provides a car window regulator, including an upper bracket, a lower bracket 8, a guide rail 5, a glass bracket 6, a drive assembly 7, and a cable 4. The upper bracket and the lower bracket 8 are fixedly installed at both ends of the guide rail 5. The glass bracket 6 is slidably installed on the guide rail 5. The drive assembly 7 and the guide rail 5 are installed on the inner panel of the car door. One end of the cable 4 is connected to the drive assembly 7, and the other end is connected to the glass bracket 6 via the upper bracket or the lower bracket 8. Specifically, the bracket body 1 is provided with welded edges or flanges, and the bracket body 1 is fixedly installed on the guide rail 5 by welding or riveting. The guide rail 5 has two sets, namely the first guide rail 51 and the second guide rail 52. The upper bracket has two sets, namely the first upper bracket and the second upper bracket. The lower bracket 8 has two sets, namely the first lower bracket 81 and the second lower bracket 82. The glass bracket 6 includes the first glass bracket 61 and the second glass bracket 62. The first upper bracket and the first lower bracket 81 are respectively installed at both ends of the first guide rail 5. The first glass bracket is installed in the first guide rail 5. The second glass bracket is installed in the second guide rail 5. The second lower bracket 82 and the second upper bracket are respectively installed at both ends of the second guide rail 52. The cable 4 includes the first cable 41, the second cable 42 and the third cable 43. The drive assembly 7 utilizes existing technology for its drive cable 4, and its principle is consistent with that of the dual-track functional window regulator structure (authorized announcement number CN220909469U). The drive assembly 7 includes a coil base 71 and a drive source 72. The coil base 71 is mounted on the inner panel of the door, and the drive source 72 is mounted on the coil base 71. One end of the first cable 41 is connected to the coil base 71, and the other end passes over the second upper bracket and connects to the second glass bracket 62. One end of the second cable 42 is connected to the coil base 71, and the other end passes over the first lower bracket 81 and connects to the first glass bracket 61. One end of the third cable 43 passes over the first upper bracket and connects to the first glass bracket 61, and the other end passes over the second lower bracket 82 and connects to the second glass bracket 62. The drive source 72 is linked to both the first and second glass brackets 61 via the cables 4. Preferably, the drive source is a motor. The lower bracket 8 utilizes existing technology.

[0045] Further, please refer to Figure 1 and Figure 5 The support body 1 is provided with a locking part 14 at the stopping point of the glass bracket 6. The locking part 14 is L-shaped or C-shaped. Specifically, the locking part 14 is integrally formed with the support body 1, replacing the conventional locking part set on the guide rail. This not only avoids the need for stamping the locking part during guide rail production, but also effectively utilizes the guide rail for the movement of the glass bracket 6. The L-shaped or C-shaped locking part 14 allows for effective contact between the support body 1 and the glass bracket 6, facilitating the limitation of the movement of the glass bracket 6. The glass bracket 6 is provided with an impact part 63 that collides with the locking part 14, and a buffer pad 631 is installed on the outer side of the impact part 63. With this structure, the glass bracket 6 will not rigidly collide with the support body 1 when it reaches the uppermost limit position of the guide rail 5, thereby reducing the impact noise and damage of the glass bracket and the support body 1, and extending the service life of the support body 1.

[0046] This utility model discloses a bracket structure and a window regulator for a vehicle window. It features mounting slots 111 at different angles, allowing the clamping head 2 to be selectively mounted on the bracket body 1 via these slots. The cable 4's routing angle meets operational requirements, enabling the same bracket to be used for various vehicle models and reducing bracket development costs. The clamping head 2 has a strip-shaped slot 21, and the bracket body 1 has a protruding edge 16. The clamping head 2 is fixedly mounted in the protruding edge 16 via an interference fit, preventing it from easily falling off. The inner wall of the through hole 22 of the clamping head 2 has a protruding ridge 221, where a steel wire rope 411 is clamped and mounted. The flange face of the adjusting screw is spherical, positioned at different heights on the upper and lower end faces of the matching guide rail 5, ensuring the guide rail 5 fits snugly against the inner door panel and improving the sealing performance between the glass and the sealing strip.
