Abstract
Description
Technical Field
[0001] This utility model relates to an improved invention of a glass lifter, and more particularly to an improved invention of a lightweight rope wheel type glass lifter. Background Technology
[0002] As the market share of electric vehicles increases, the weight control of components becomes extremely stringent. Traditional monorail window regulators use metal for both the guide rail and the glass bracket, weighing approximately 1.1 kg. The mounting points where the metal guide rail connects to the sheet metal inside the door, as well as the mounting plate between the metal guide rail and the motor, all require assembly. This results in an assembly process that requires 4-5 people and a production cycle of approximately 20-30 seconds, increasing assembly costs. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a lightweight rope wheel type glass lifter.
[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: A lightweight rope-wheel type window regulator includes a steel wire rope, a guide rail, a motor, and a glass bracket. The glass bracket is movably mounted on the guide rail and connected to the steel wire rope, which is driven by the motor. The guide rail and glass bracket are both made of plastic. One side of the guide rail integrates a mounting bracket and a motor mounting plate. The motor mounting plate is located on the mounting bracket and has motor fixing bolts that assemble with the motor. The steel wire rope is equipped with rollers, which are distributed vertically on the mounting bracket and have fixing plates. The guide rail also integrates mounting points for connection to the sheet metal inside the car door, and mounting bolts are provided at these mounting points.
[0005] The mounting bracket is triangular in shape and has staggered reinforcing ribs.
[0006] The glass bracket is provided with glass fixing holes distributed on the left and right sides, as well as two tension springs.
[0007] The motor is a lightweight motor.
[0008] The beneficial effects of this utility model are that the improved lightweight rope wheel type window regulator uses plastic guide rails and glass brackets, and the guide rails integrate mounting brackets, motor mounting plates and mounting points for connection with the sheet metal inside the car door. Equipped with a lightweight motor, the weight can be controlled at around 700g, a weight reduction of more than 30%. Only three people are needed while maintaining the same production cycle, saving assembly costs. Attached Figure Description
[0009] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.
[0010] Figure 1 This is a schematic diagram of the structure of this utility model.
[0011] Figure 2 This is a rear view of the structure of this utility model. Detailed Implementation
[0012] The accompanying drawings illustrate the structure of this utility model, and further details will be described below with reference to the drawings. In this embodiment, see the attached drawings. Figure 1-2 This lightweight cable-driven window regulator includes a steel wire rope 1, a guide rail 2, a motor 3, and a glass bracket 4. The glass bracket 4 is movably mounted on the guide rail 2 and connected to the steel wire rope 1. The steel wire rope 1 is driven by the motor 3. Both the guide rail 2 and the glass bracket 4 are made of plastic. A mounting bracket 5 and a motor mounting plate 6 are integrated on one side of the guide rail 2. Preferably, the guide rail 2, the mounting bracket 5, and the motor mounting plate 6 are integrally injection molded. The motor mounting plate 6 is located on the mounting bracket 5 and is provided with motor fixing bolts 7. The motor fixing bolts 7 are assembled and cooperate with the motor 3. The steel wire rope 1 is equipped with rollers 8, which are distributed vertically on the mounting bracket 5 and are equipped with fixing plates 9. The guide rail 2 also integrates mounting points 10 for connection with the sheet metal inside the car door, and mounting bolts are provided at the mounting points 10.
[0013] In this utility model, the plastic guide rail 2 integrates mounting points 10 for connection with the inner sheet metal of the car door. The mounting points 10 are directly injection molded onto the plastic guide rail 2 during injection molding. Preferably, there are three mounting points 10 arranged in a triangular distribution to improve connection stability. Mounting bolts are provided at the mounting points 10, allowing for quick connection between the plastic guide rail 2 and the inner sheet metal of the car door, eliminating the need for additional connecting parts on the plastic guide rail 2. At the same time, the plastic guide rail 2 integrates a motor mounting plate 6, which has motor fixing bolts 7, allowing the motor 3 to be directly mounted on the guide rail 2, improving assembly accuracy.
[0014] As a further improved embodiment, the mounting bracket 5 is triangular in shape and has staggered reinforcing ribs 11 on it to enhance structural strength and compactness.
[0015] As a further improved embodiment, the glass bracket 4 is provided with glass fixing holes 12 distributed on the left and right and two tension springs 13. The glass fixing holes 12 are used to fix the glass bracket 4 to the glass bracket 4, and the tension springs 13 are used to connect the glass bracket 4 and the steel wire rope 1 to achieve buffering.
[0016] As a further improvement, the motor 3 is a lightweight motor, that is, an existing motor whose material selection and structural design have been optimized to reduce weight.
[0017] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
