[0005] To solve the above-mentioned technical problems, this utility model provides a car window regulator with automatic adjustment of steel wire rope, including a mounting base, a slide rail, a steel wire rope, a motor and a reel mounted on the mounting base, a sliding plate mounted on the slide rail for cooperating with the glass, pulley seats mounted on both sides of the slide rail, one side of the steel wire rope is wound on the reel, and the other side of the steel wire rope passes around the pulley seat and connects to the sliding plate, and also includes an adjustment mechanism mounted on the sliding plate for adjusting the length of the steel wire rope, the adjustment mechanism including a winding post mounted on the sliding plate for rotating the steel wire rope, a stepper motor mounted on one side of the sliding plate, and the extension shaft of the stepper motor connected to the winding post.

[0006] In a preferred embodiment, a V-shaped wheel is fixed on the winding post, the wire rope is clamped inside the V-shaped wheel, and a measuring mechanism is also provided inside the slide plate to measure the tension of the wire rope.

[0007] In a preferred embodiment, the measuring mechanism includes a tension sensor connected to a slide plate on one side, a spring connected to the other side of the tension sensor, a ring connected to the other side of the spring, and a steel wire rope passing through the ring and wrapped around a V-shaped wheel.

[0008] In a preferred embodiment, a motor mount is provided on one side of the skateboard, and a stepper motor is mounted on the motor mount.

[0010] In the preferred embodiment, a mounting groove is provided on the inner side of the skateboard, and the V-shaped wheel and the measuring mechanism are installed in the mounting groove.

[0011] The beneficial effects of this utility model are as follows: Because this utility model is equipped with a car window glass lifter with automatic steel wire rope adjustment, by setting a stepper motor on one side of the winding column, and controlling the motor to rotate and wind the steel wire rope through the system, it is not necessary for the worker to rotate the winding column. The winding column can be rotated in time to achieve the tightening of the steel wire rope, thus improving work efficiency. Attached Figure Description

[0016] Please refer to Figures 1-2. This application provides a technical solution: a car window regulator with automatic adjustment of steel wire rope, including a mounting base 10, a slide rail 7, a steel wire rope 3, a motor 1 and a reel 6 mounted on the mounting base 10, a sliding plate 5 mounted on the slide rail 7 for cooperating with the glass, pulley seats 4 mounted on both sides of the slide rail 7, one side of the steel wire rope 3 is wound on the reel 6, and the other side of the steel wire rope 3 passes around the pulley seat 4 and connects to the sliding plate 5. It also includes an adjustment mechanism mounted on the sliding plate 5 for adjusting the length of the steel wire rope 3. The adjustment mechanism includes a winding post 21 rotatably mounted on the sliding plate 5 for winding the steel wire rope 3, and a stepper motor 22 mounted on one side of the sliding plate 5. The extension shaft of the stepper motor 22 is connected to the winding post 21.

[0017] When the wire rope 3 becomes loose, the controller in the system controls the stepper motor 22 to rotate and drive the winding column 21 to tighten the wire rope 3. Since the stepper motor 22 has a self-locking function, the wire rope 3 can remain stationary after being tightened. This eliminates the need for manual intervention to rotate the winding column 21, thereby freeing up manpower and improving work efficiency.

[0018] In the preferred embodiment, a V-shaped wheel 23 is fixedly mounted on the winding post 21, the wire rope 3 is clamped in the V-shaped wheel 23, and a measuring mechanism is also provided in the slide plate 5 to measure the tension of the wire rope 3.

[0019] The winding point of the V-shaped wheel 23 corresponds to the through hole of the steel wire rope 3 on the slide plate 5, so that the packaging steel wire rope 3 is perpendicular to the rotation axis of the V-shaped wheel 23.

[0020] In a preferred embodiment, the measuring mechanism includes a tension sensor 24 connected to the slide plate 5 on one side, a spring 25 connected to the other side of the tension sensor 24, a ring 26 connected to the other side of the spring 25, and a steel wire rope 3 passing through the ring 26 and wrapped around the V-shaped wheel 23.

[0021] The measuring mechanism operates on the following principle: During operation, the lower end of the ring 26 contacts the wire rope 3, which is taut. The spring 25 is stretched, and the tension sensor displays an initial tension. When the wire rope becomes slack, it bends under the tension of the spring 25, reducing the pre-set tension. This indicates that the wire rope is slack. The system controller then controls the stepper motor 22 to rotate, thereby tightening the wire rope 3. Timely tightening prevents the wire rope 3 from becoming slack and tangling.

[0022] For tension sensors, you can choose the TJL-12 detection sensor from Anhui Tianguang Sensor Co., Ltd.

[0023] In a preferred embodiment, a motor mount 27 is provided on one side of the slide plate 5, and a stepper motor 22 is mounted on the motor mount 27.

[0024] In the preferred embodiment, the V-shaped wheel 23 is made of stainless steel. Using stainless steel primarily improves the wear resistance and water resistance of the V-shaped wheel 23.

[0025] In a preferred embodiment, a mounting groove 51 is provided on the inner side of the skateboard 5, and the V-shaped wheel 23 and the measuring mechanism are disposed in the mounting groove 51.

[0026] In this way, all the mechanisms are set in the mounting slot 51, so they will not interfere with external equipment.

[0027] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
