Description

Technical Field

[0001] This utility model relates to the field of automotive window lifting technology, specifically to a steel wire rope guide structure for automotive window lifting. Background Technology

[0002] The window lift system is generally driven by a lifter located below the window glass, which moves the window glass up and down along the guide rails on both sides of the car frame.

[0003] Traditional automotive window lift rails use fully slack steel cables for easy installation and adjustment. However, slack cables are prone to detaching from the guide wheels (derailment). Once derailed, reinstallation is extremely difficult, significantly reducing installation efficiency and potentially damaging the cables. To prevent derailment, the motor fully tensions the cables before installation. However, a taut cable acts like a rigid rod, forcibly connecting the two rails, leaving workers with almost no flexibility to fine-tune their positions to align with the mounting holes on the door. This makes installation laborious and prone to generating assembly stress. To address these issues, we propose a new automotive window lift steel cable guide structure. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a guide structure for automotive window lifting wire ropes, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a steel wire rope guide structure for lifting automobile windows, including a guide rail, a rope made of steel wire, and a glass bracket slidably connected to the guide rail. The glass bracket is fixedly connected to the rope. The side of the guide rail is also provided with a guide wheel that slidably contacts the glass bracket. It also includes an auxiliary mechanism. The auxiliary mechanism includes an outer protective cover fixed to the side of the guide rail. The outer protective cover has a cavity, and a transmission rod is provided in the cavity. The auxiliary mechanism also includes an adjusting shaft spun on the guide rail. The end of the adjusting shaft is provided with a main disc-shaped shaft. The eccentric shaft on the side of the main disc-shaped shaft is rotatably connected to the center of the transmission rod. The end of the transmission rod is rotatably connected to the eccentric shaft on the side of the auxiliary disc-shaped shaft. The auxiliary disc-shaped shaft is rotatably connected to the side of the inner protective sleeve fixed on the guide rail. A lead screw is fixed to the inner side of the secondary disc shaft. A plate nut is threaded onto the lead screw. A U-shaped buckle is fixedly installed on the side of the plate nut. The U-shaped buckle is slidably connected to the guide rail. Two guide rings are fixed to the side of the guide rail. The end of the rope passes through the two guide rings. The U-shaped buckle is located between the two guide rings.

[0006] Preferably, rotating the adjusting shaft can drive the main disc-shaped shaft to rotate, and through the transmission rod, drive the auxiliary disc-shaped shaft to rotate, thereby causing the lead screw to rotate synchronously.

[0007] Preferably, the rotation of the lead screw can drive the plate nut and the U-shaped buckle to slide along the inner protective sleeve.

[0008] Preferably, when the U-shaped buckle slides towards the inner protective sleeve, it can cooperate with the two guide rings to clamp the rope.

[0009] Preferably, when the U-shaped buckle clamps the rope, it can be used as a dividing point to adjust the rope between the two guide wheels on a single guide rail to a taut state and the rope between the two guide rails to a slack state.

[0010] Preferably, both the inner protective sleeve and the secondary disc-shaped shaft are located in the cavity inside the outer protective cover.

[0011] Preferably, both the plate nut and the lead screw are located in the cavity inside the inner casing.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This automotive window regulator cable guide structure allows installers to rotate an adjusting shaft while installing a pair of guide rails onto the car door, causing the U-shaped clips to clamp the cable. The cable inside each individual guide rail is taut, while the cable between the two guide rails is slack. The tautness inside the guide rails ensures that the cable remains firmly against the guide wheel, completely eliminating the risk of the cable detaching from the guide wheel during movement and installation. The slack between the two guide rails allows for flexible adjustment of the distance between them, making it easy for workers to align with the mounting holes on the car door without having to pull the taut cable, significantly reducing installation difficulty and labor intensity.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-5 A guide structure for a steel wire rope for lifting automotive windows includes a guide rail 1, a rope body 3 made of steel wire, and a glass bracket 2 slidably connected to the guide rail 1. The glass bracket 2 is fixedly connected to the rope body 3. A guide wheel 4 that slidably contacts the glass bracket 2 is also provided on the side of the guide rail 1. The guide structure also includes an auxiliary mechanism 5. The auxiliary mechanism 5 includes an outer protective cover 59 fixed to the side of the guide rail 1. The outer protective cover 59 has a cavity, and a transmission rod 58 is provided in the cavity.

[0017] The auxiliary mechanism 5 also includes an adjusting shaft 51 screwed onto the guide rail 1. The installation worker only needs to use a screwdriver to turn the adjusting shaft 51 to control the complex clamping and releasing actions, without the need for special tools, which greatly reduces the difficulty of operation and training costs. The rotation of the adjusting shaft 51 can be precisely converted into linear displacement, allowing the worker to fine-tune the clamping force and tension, avoiding damage to the wire rope due to overtightening. The end of the adjusting shaft 51 is provided with a main disc-shaped shaft 510, and the eccentric shaft on the side of the main disc-shaped shaft 510 is rotatably connected to the center of the transmission rod 58; the end of the transmission rod 58 is rotatably connected to the eccentric shaft on the side of the auxiliary disc-shaped shaft 57, and the auxiliary disc-shaped shaft 57 is rotatably connected to the side of the inner protective sleeve 56 fixed on the guide rail 1; the inner protective sleeve 56 and the auxiliary disc-shaped shaft 57 are both located in the cavity inside the outer protective cover 59, and the plate nut 54 and the screw 55 are both located in the cavity inside the inner protective sleeve 56.

[0018] A lead screw 55 is fixed to the inner side of the secondary disc shaft 57. A plate nut 54 is threaded onto the lead screw 55. A U-shaped buckle 53 is fixedly installed on the side of the plate nut 54. The U-shaped buckle 53 is slidably connected to the guide rail 1. Rotating the adjusting shaft 51 can drive the main disc shaft 510 to rotate, and through the transmission rod 58, drive the secondary disc shaft 57 to rotate, thereby causing the lead screw 55 to rotate synchronously. The rotation of the lead screw 55 can drive the plate nut 54 and the U-shaped buckle 53 to slide along the inner protective sleeve 56. When the U-shaped buckle 53 slides towards the inner protective sleeve 56, it can cooperate with the two guide rings 52 to clamp the rope 3. The side of the guide rail 1 is fixed There are two guide rings 52. The end of the rope 3 passes through the two guide rings 52. A U-shaped buckle 53 is set between the two guide rings 52. When the U-shaped buckle 53 clamps the rope 3, it can adjust the rope 3 between the two guide wheels 4 on a single guide rail 1 to a taut state and the rope 3 between the two guide rails 1 to a slack state, with the U-shaped buckle 53 as the dividing point. The U-shaped structure of the U-shaped buckle 53 can well accommodate and compress the wire rope, provide uniform clamping force, and provide a larger and smoother contact surface, which can effectively avoid pinching or scratching the nylon coating on the surface of the rope 3 and extend the life of the rope 3.

[0019] Working principle: Before installing the pair of guide rails 1 for the car window lift on the car door, the rope 3 needs to be loosened to facilitate the installation process. Before installation, the adjusting shaft 51 on the guide rail 1 is rotated. Because the eccentric shaft on the side of the main disc-shaped shaft 510 at the end of the adjusting shaft 51 is rotatably connected to the center of the transmission rod 58, and the end of the transmission rod 58 is rotatably connected to the eccentric shaft on the side of the auxiliary disc-shaped shaft 57, when the adjusting shaft 51 drives the main disc-shaped shaft 510 to rotate, the transmission rod 58 can simultaneously drive the auxiliary disc-shaped shaft 57 to rotate on the side of the inner protective sleeve 56, which is fixedly connected to the guide rail 1. The screw 55 fixed inside the auxiliary disc-shaped shaft 57 rotates synchronously. Since the plate nut 54 fixed to the end of the U-shaped buckle 53 is also threadedly connected to the screw 55, after the screw 55 rotates, it can drive the plate nut 54 and the U-shaped buckle 53 to slide towards the inner protective sleeve 56, and the rope... Both ends of the rope 3 pass through two guide rings 52 fixed to the side of the guide rail 1. A U-shaped buckle 53 is set between the two guide rings 52. After the U-shaped buckle 53 slides, it can cooperate with the guide rings 52 to clamp the end of the rope 3. Thus, the rope 3 is divided into two states based on the tension and the U-shaped buckle 53 as the dividing point. The rope 3 is taut between the two guide wheels 4 on a single guide rail 1, and slack between the two guide rails 1. Therefore, the distance between the two guide rails 1 can be flexibly adjusted, and the rope 3 can be prevented from detaching from the guide wheels 4. This facilitates the installation of the guide rail 1. After the guide rail 1 is installed, the U-shaped buckle 53 is driven to slide outward by adjusting the shaft 51 to release the restriction on the rope 3. Then, the tightening motor in the car window regulator is immediately started to tighten the rope 3 and adjust the entire rope 3 to a taut state to meet the application requirements of car window lifting.

[0020] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
