Description

Technical Field

[0001] This utility model relates to a sliding plate for a window lifter that integrates a spring groove. Background Technology

[0002] In the automotive manufacturing industry, window regulators, as core components enabling the raising and lowering of vehicle windows, directly impact vehicle user experience and safety due to their structural stability and operational reliability. Among these, wire rope window regulators are widely used in various passenger and commercial vehicles due to their compact structure and small footprint. This type of regulator typically consists of a motor, wire rope, pulleys, a sliding plate, and a cable groove. The sliding plate and cable groove, serving as the guide and constraint structure for the wire rope, are crucial to the overall performance of the lifting system. However, existing technologies with sliding plate and cable grooves still have several drawbacks: First, the fit between the cable groove and the wire rope is difficult to control precisely. Excessive gap can cause shaking and abnormal noise during operation, while insufficient gap increases frictional resistance and accelerates component wear. Second, the guide structure design is simple and lacks an effective anti-derailment mechanism. After long-term, high-frequency use, the wire rope is prone to detachment, leading to regulator failure, increased maintenance costs for users, and disruption to normal vehicle operation. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a glass lifter slide plate with an integrated spring groove. Its structure is simple and compact, effectively integrating the spring groove and the steel cable rivet limiting groove structure, making the structure more convenient to assemble and providing good performance.

[0004] To achieve the above objectives, this utility model provides a sliding plate for a glass lifter integrated with spring grooves, including a plate body. The plate body is provided with a first spring groove and a second spring groove, and springs are respectively provided in the first spring groove and the second spring groove. The first spring groove and the second spring groove are arranged opposite to each other. The plate body is provided with a first groove at the opening of the first spring groove and a second groove at the opening of the second spring groove. A depth difference is formed between the first groove and the second groove. The first groove and the second groove intersect. The plate body is provided with a guide boss at the intersection of the first groove and the second groove.

[0005] The advantages of this design are as follows: By setting the first and second spring grooves relatively opposite to each other on the plate, synchronous installation and positioning of the two springs can be achieved, making the force on the slide plate more even and avoiding uneven wear and jamming caused by unilateral force, thus significantly improving the smoothness of the window regulator operation. The first and second grooves adopt a depth difference and staggered arrangement structure, which can achieve layered guidance of the two steel cables without interference, fundamentally solving the problems of mutual compression, friction, abnormal noise, and derailment of steel cables in traditional structures. The guide boss is set at the staggered position, which can accurately limit and guide the steel cables, reduce the running resistance and wear of the steel cables, and extend their service life. This integrated structure integrates the spring installation and steel cable guidance functions on the same slide plate, reducing the number of parts and assembly processes, reducing mold investment and processing complexity, improving versatility and production efficiency, while reducing the overall size, adapting to the limited installation space inside the car door, and meeting the development needs of lightweight, high reliability, and low cost of automotive window regulators.

[0006] As a further feature of this utility model, the plate body is provided with guide bosses on both sides of the guide boss, the guide bosses are provided with guide grooves for guiding steel cables through, and the guide bosses are provided with hollow grooves.

[0007] The beneficial effects of this design are as follows: By adding guide bosses and guide grooves on both sides of the guide boss, the steel cable can be precisely guided in segments, further improving the stability of the cable's operation, avoiding swaying, jumping, and noise, and making the window lifting smoother. The guide grooves and cable grooves form a continuous guiding channel, conforming to the movement trajectory of the steel cable, reducing friction loss, lowering the motor load, and improving the response speed and service life of the lifter. The hollowed-out grooves on the guide bosses effectively reduce the overall weight of the slide plate while ensuring structural strength, achieving lightweight design and reducing material consumption and manufacturing costs. The hollowed-out structure also improves the injection molding processability, reducing defects such as shrinkage marks and deformation, and increasing the product qualification rate. The symmetrical arrangement of the double guide bosses makes the slide plate more evenly stressed, less prone to deformation and breakage over long-term use, improving structural durability and stability, reducing after-sales failure rates, and optimizing overall assembly efficiency and user experience.

[0008] As a further feature of this invention, the inner walls of the first spring groove and the second spring groove are provided with abutting ribs, which abut against the side wall of the spring.

[0009] The beneficial effects of this design are as follows: The abutment ribs on the inner walls of the first and second spring slots ensure tight contact with the spring sidewalls, achieving precise radial positioning of the spring. This prevents the spring from wobbling, shifting, twisting, or tilting within the slots, ensuring the spring always extends and contracts in the correct direction, providing stable cushioning and preload. The multi-point contact of the abutment ribs reduces the contact area between the spring and the slot wall, lowering frictional resistance and making spring extension and contraction smoother, preventing jamming and failure. This structure achieves reliable limiting without additional positioning components, simplifying the assembly process and improving production efficiency. The abutment ribs disperse the spring force, reducing localized stress concentration, minimizing the risk of spring slot cracking and deformation, and improving structural strength and service life. Overall, it enhances the stability, quietness, and durability of the window regulator, reduces the failure rate, and improves the overall vehicle ride comfort.

[0010] As a further feature of this invention, the first spring groove and the second spring groove are respectively provided with limiting walls at their openings to prevent the spring from disengaging from the first spring groove or the second spring groove.

[0011] The benefits of this design are as follows: By placing a limiting wall at the opening of the spring slot, the axial displacement of the spring is effectively restricted, preventing the spring from dislodging from the slot during extension, vibration, or assembly. This avoids serious malfunctions such as jamming or failure of the lifter, improving structural reliability and safety. The limiting wall and the spring slot form a closed limiting space, ensuring the spring remains stable in its installation position and continuously provides stable elastic force, improving the smoothness of glass lifting. This limiting structure is integrally molded, eliminating the need for additional clips, pins, or other accessories, simplifying the structure, reducing costs, improving assembly efficiency, and preventing the loss or improper installation of small parts. The limiting wall also enhances the structural strength of the slot, resisting the long-term force of the spring, reducing cracking and deformation, extending the service life of the slide plate, improving the overall stability and durability of the glass lifter, and reducing maintenance costs.

[0012] As a further feature of this utility model, the plate body is provided with a plurality of reinforcing ribs on the outer walls of the first spring groove and the second spring groove, respectively.

[0013] The beneficial effects of this design are as follows: Multiple reinforcing ribs on the outer wall of the spring groove significantly improve the structural strength and rigidity of the groove, resisting the forces of the spring and the tension of the steel cable. This prevents deformation, cracking, and collapse after long-term use, extending the lifespan of the sliding plate. The rational distribution of the reinforcing ribs effectively disperses stress, improving overall fatigue resistance and adapting to high-frequency lifting conditions. The reinforcing rib structure increases strength without significantly increasing weight or material consumption, maintaining a lightweight advantage and not affecting installation or compatibility. The structure is integrally injection molded, resulting in a simple, low-cost, and highly efficient production process without the need for additional processing steps. By enhancing the stability of the spring groove structure, the precise working positions of the spring and steel cable are ensured, improving the operating accuracy, stability, and quietness of the window regulator, reducing the failure rate, and enhancing product quality and market competitiveness.

The abutting ribs 21 adopt a multi-point contact form, reducing the contact area between the spring 4 and the groove wall, reducing frictional resistance, making the extension and contraction of the spring 4 smoother, and avoiding jamming and failure problems.

The limiting walls 22 and the spring grooves form a closed limiting space, ensuring that the spring 4 remains stable in the installation position, continuously providing stable elastic force, and improving the smoothness of glass lifting. This limiting structure is integrally molded, eliminating the need for additional clips, pins, or other accessories, simplifying the structure, reducing costs, improving assembly efficiency, and preventing problems such as lost or improperly installed small parts.
