Abstract
Description
Technical Field
[0001] This application relates to an integrated dual-rail window regulator, belonging to the field of automotive parts technology. Background Technology
[0002] Rope pulley window regulators are one of the most commonly used window regulators in automobiles. In rope pulley window regulators, a sleeve is typically used to guide the steel cable (wire rope), preventing it from deviating from the preset track and causing the glass to tilt or shift. This is exemplified by the sleeve used in patent CN 217054814 U, a window regulator. This patent further incorporates a spring between the sleeve and the opening of the winding box to address the technical problem of stress and strain caused by directly inserting the sleeve connector into the winding box in existing technologies. Simultaneously, the spring automatically expands and contracts according to changes in cable tension during glass raising and lowering, consistently applying a certain elastic force to the cable to maintain appropriate tension.
[0003] However, the following problems still cannot be solved: the use of sheathed steel cables (with an outer sheath added to the steel cable) causes the steel cable to slide and rub inside the sheath, resulting in repeated wear of a large area of the steel cable, reducing the service life of the steel cable, and increasing production costs.
[0004] In addition, the existing dual-rail glass lifters are split rails, which require two sets of stamping dies and two processing steps during production; the installation and application process requires welding the bracket; resulting in a complicated process, low efficiency and high production cost.
[0005] Therefore, this application aims to prepare a double-rail glass lifter without a protective tube on the outside of the steel cable, which solves the problem of steel cable wear caused by the sleeve. At the same time, through specific structural improvements, it can ensure that the steel cable does not deviate from the preset track direction, and also ensure that the steel cable has a certain "elastic force" to cope with the tension changes during the glass lifting process, thereby reducing production costs and improving production efficiency. Utility Model Content
[0006] To address the aforementioned issues, this application proposes an integrated dual-track glass lifter. The tubeless steel cable in this device not only solves the problem of wear and tear on traditional steel cables caused by the sleeve, but also ensures that the cable does not deviate from the preset track direction even after the sleeve is removed. Furthermore, it maintains a certain degree of elasticity in the cable to cope with tension changes during glass lifting. Moreover, the integrated dual-track design reduces production costs and improves production efficiency.
[0007] The specific technical solution of this application is as follows:
[0008] This application provides an integrated dual-rail glass lifter, comprising: an integral dual-rail component, and two slide rails disposed on both sides of the integral dual-rail component; a first slider and a second slider are slidably connected to the inner walls of the two slide rails respectively; a first limiting groove and a second limiting groove for limiting steel cables are respectively provided on both sides of the upper surface of the first slider and the second slider.
[0009] The first limiting groove includes a first channel and a second channel connected in sequence; the inner diameter of the second channel is larger than the inner diameter of the first channel; a tension control elastic element with the same direction as the steel cable is provided in the second channel; a stabilizing plate is provided at the end of the tension control elastic element away from the first channel;
[0010] The end of the steel cable in the first limiting groove passes through the first channel and the inner diameter of the tension control elastic element in sequence and then connects to the bottom of the stabilizing plate.
[0011] Both the tension control elastic element and the stabilizing plate are tightly attached to the inner wall of the second channel.
[0012] Optionally, both the first limiting groove and the second limiting groove are arc-shaped limiting grooves; the arc-shaped openings of the first limiting groove and the arc-shaped openings of the second limiting groove face each other.
[0013] Optionally, the first limiting groove and the second limiting groove in the first slider extend from the first slider towards the slide rail track and extend to the bottom of the first slider;
[0014] The first limiting groove and the second limiting groove in the second slider extend from the second slider toward the slide rail and extend to the bottom of the second slider.
[0015] Optionally, the tension control elastic element includes a high-carbon steel spring.
[0016] Optionally, the shape of the stabilizing plate is adapted to the end of the tension control elastic element, and the diameter of the stabilizing plate is the same as the outer diameter of the tension control elastic element.
[0017] Furthermore, a piston is provided at the bottom of the stabilizing plate, extending into the tension control elastic element; the end of the steel cable in the first limiting groove is connected to the piston.
[0018] The beneficial effects that this application may produce include, but are not limited to:
[0019] 1. The first limiting groove on the upper surface of the slider in this application includes a first channel and a second channel connected in sequence; the inner diameter of the second channel is larger than the inner diameter of the first channel; a tension control elastic element (specifically a high carbon steel spring in this embodiment) with the same direction as the steel cable is provided in the second channel; a stabilizing plate is provided at the end of the tension control elastic element away from the first channel;
[0020] The end of the steel cable in the first limiting groove passes sequentially through the first channel and the inner diameter of the tension control elastic element before connecting to the bottom of the stabilizing plate. During different stages of glass lifting, the tension of the steel cable changes. The tension control elastic element automatically expands and contracts according to these tension changes, consistently applying a certain elastic force to the steel cable to maintain appropriate tension and ensure smooth and stable glass lifting. This further effectively prevents the other end of the steel cable in the first limiting groove from slipping out of the groove or climbing out of the winding wheel due to improper tension control, preventing the steel cable from deviating from the preset track direction. The inner diameter of the second channel is larger than that of the first channel, ensuring that the tension control elastic element does not slip into the first channel when subjected to the tension of the steel cable. The bottom end of the tension control elastic element (the end furthest from the stabilizing plate) remains stable at the junction of the first and second channels.
[0021] Furthermore, this embodiment uses a tubeless steel cable to solve the problem of wear and tear caused by the sleeve of traditional steel cables, and it is an integrated double guide rail, which reduces production costs and improves production efficiency.
[0022] 2. Furthermore, the tension control elastic element includes a high-carbon steel spring; the tension control elastic element has a certain degree of contraction in the compressed state, and after contraction, it can make the steel cable have a certain degree of tightness, so as to prevent the steel cable from derailing or climbing in the winding wheel.

[0039] As a specific implementation method, such as Figure 1-6 As shown. An integrated dual-track glass lifter includes: an integral dual-track component 1, and two slide rails 2 disposed on both sides of the integral dual-track component 1; a first slider 3 and a second slider 4 are slidably connected to the inner walls of the two slide rails 2 respectively; the first slider 3 and the second slider 4 are centrally symmetrical when they are on the same horizontal plane (i.e., at the same height); a first limiting groove 5 and a second limiting groove 6 for limiting steel cables are respectively provided on both sides of the upper surface of the first slider 3 and the second slider 4; (at this time, the first limiting groove 5 of the first slider 3 and the first limiting groove 5 of the second slider 4 are centrally symmetrical; the second limiting groove 6 of the first slider 3 and the second limiting groove 6 of the second slider 4 are centrally symmetrical).
[0040] The first limiting groove 5 includes a first channel 501 and a second channel 502 connected in sequence; the inner diameter of the second channel 502 is larger than the inner diameter of the first channel 501; a tension control elastic element 8 (specifically a high carbon steel spring in this embodiment) with the same direction as the steel cable is provided in the second channel 502, and the bottom of the tension control elastic element 8 is in close contact with the bottom inner wall of the second channel 502; a stabilizing plate 9 is provided at the end (top) of the tension control elastic element 8 away from the first channel 501;
[0041] The end of the steel cable in the first limiting groove 5 passes through the inner diameter of the first channel 501 and the tension control elastic element 8 in sequence and then connects to the bottom of the stabilizing plate 9; both the tension control elastic element 8 and the stabilizing plate 9 are in close contact with the inner wall of the second channel 502. Both the first limiting groove 5 and the second limiting groove 6 are arc-shaped limiting grooves; the arc-shaped openings of the first limiting groove 5 and the second limiting groove 6 face each other. The inner wall shape of the arc-shaped limiting groove is adapted to the shape of the steel cable; the depth of the arc-shaped limiting groove is twice the thickness (diameter) of the steel cable. (The specific depth can be adjusted according to actual conditions, all within the scope of protection of this application).
[0042] The shape of the stabilizing plate 9 is adapted to the end of the tension control elastic element 8, and the diameter of the stabilizing plate 9 is the same as the outer diameter of the tension control elastic element 8.
[0043] The tension control elastic element 8 can be installed in the second channel 502 either manually or mechanically; both are within the scope of protection of this application.
[0044] The tension control elastic element 8 has a certain degree of contraction in the compressed state, which enables the steel cable to have a certain tightness after contraction, preventing the steel cable from derailing or climbing out of the winding wheel 11. The compressed state refers to the maximum tension applied by the steel cable to the tension control elastic element 8 during the glass lifting process; only in this way can the steel cable have a certain tightness and prevent the steel cable from derailing or climbing out of the winding wheel 11.
[0045] This embodiment uses an integrated double guide rail, which, compared to the traditional separate double guide rail, only requires one stamping die and one-time processing during production. Furthermore, no separate welding bracket is needed during the installation and application of the car door, saving time and effort and increasing efficiency. In this embodiment, the steel cable is a non-tube type, meaning it is not fitted with a sleeve. The other end of the steel cable located in the first limiting groove 5 is connected to the winding wheel 11. Figure 4-6 As shown, the dual-rail glass lifter also includes a first steel cable 701, a second steel cable 702, and a third steel cable 703; it also includes a first pulley 12, a second pulley 13, a third pulley 14, and a fourth pulley 15. The first pulley 12 and the third pulley 13 are both located on the upper part of the integrated dual-rail component 1, and the second slider 13 and the fourth pulley 15 are both located on the lower part of the integrated dual-rail component 1. The first pulley 12 and the second pulley 13 are both close to the slide rail 2 at the first slider 3, and the straight line formed between the first pulley 12 and the second pulley 13 is parallel to the length direction of the slide rail 2. The first slider 3 is located between the first pulley 12 and the second pulley 13. The third pulley 14 and the fourth pulley 15 are both close to the slide rail 2 at the second slider 4, and the straight line formed between the third pulley 14 and the fourth pulley 15 is parallel to the length direction of the slide rail 2. The second slider 4 is located between the third pulley 14 and the fourth pulley 15.
[0046] The winding wheel 11 is mounted on the integrated double guide rail 1. The winding wheel 11 is located within the area formed by the connection of the first pulley 12, the second pulley 13, the third pulley 14, and the fourth pulley 15. The winding wheel 11 can be located in the middle of the area or any other position. In this embodiment, the winding wheel 11 is located on the left side of the area (i.e., relatively close to the second slider 4).
[0047] One end of the first steel cable 701 is located in the first limiting groove 5 of the first slider 12, and the other end is rotated counterclockwise upwards around the first pulley 3 and then connected to the winding wheel 11 (specifically, it is wound clockwise around the upper side wall of the winding wheel 11). One end of the second steel cable 702 is located in the first limiting groove 5 of the second slider 4, and the other end is rotated counterclockwise downwards around the fourth pulley 15 and then connected to the winding wheel 11 (specifically, it is wound counterclockwise around the lower side wall of the winding wheel 11).
[0048] One end of the third steel cable 703 is set in the second limiting groove 6 of the first slider 3, and the other end goes down clockwise around the second pulley 13, then goes up counterclockwise around the third pulley 14, and then goes down into the second limiting groove 6 of the second slider 4.
[0049] During operation, the glass is held between the first slider 3 and the second slider 4. When the car glass needs to be raised, the motor drives the winding wheel 11 to rotate clockwise (there are usually up and down control buttons or handles in the car). This drives the first steel cable 701 to apply an upward pulling force to the first slider 3. This pulling force enables the first steel cable 701 to overcome the weight of the glass and move the glass upward. At this time, the first steel cable 701 located in the first limiting groove 5 will apply a pulling force to the stabilizing plate 9 connected to the end of the first steel cable 701, and then apply a pulling force to the tension control elastic element 8 connected to the end of the stabilizing plate 9. Under the action of this pulling force, the tension control elastic element 8 will contract to a certain extent.
[0050] Since one end of the third steel cable 703 is located in the second limiting groove 6 of the first slider 3, the first slider 3 will apply an upward pulling force to the third steel cable 703 during the upward movement of the first slider 3, thereby causing the other end of the third steel cable 703 to move upward on the second slider 13 (at this time, the length of the third steel cable 703 between the first slider 3 and the second pulley 4 gradually increases, and the length of the third steel cable 703 between the third pulley 14 and the second slider 13 gradually decreases).
[0051] Simultaneously, as the winding wheel 11 rotates clockwise, one end of the second steel cable 702, which is wound around the winding wheel 11, will be released from the winding wheel 11. The other end of the second steel cable 702 moves synchronously with the second slider 13. The steel cable is in a free and relaxed state. The tension control elastic element 8 in the compressed state inside the second slider 13 will rebound under its own characteristics, so that the steel cable is in close contact with the winding wheel 11 and the pulley, preventing the steel cable from derailing or climbing, and ensuring its smooth operation.
[0052] When the glass needs to be lowered, the motor drives the winding wheel 11 to rotate counterclockwise, causing the second steel cable 702 to apply a downward pulling force to the second slider 4, causing the second slider 4 to move downward. This pulling force allows the first steel cable 701 to overcome the friction between the glass and the adhesive strip (as is known in the art, the adhesive strip is embedded in the window frame groove, and the edge of the glass must be completely in contact with the adhesive strip during installation), thus enabling the glass to move downward. During the descent, the second steel cable 702 ultimately applies a pulling force to the stabilizing plate 9 connected to the end of the second steel cable 702 and the tension control elastic element 8 connected to the end of the stabilizing plate 9. Under the action of this pulling force, the tension control elastic element will contract to a certain extent.
[0053] Since one end of the third steel cable 703 is located in the second limiting groove 6 of the second slider 4, the second slider 4 will exert a downward pulling force on the third steel cable 703 during the descent of the second slider 4, thereby causing the other end of the third steel cable 703 to move downward in the first slider 3.
[0054] Simultaneously, when the winding wheel 11 rotates counterclockwise, one end of the first steel cable 701, which is wound on the winding wheel 11, will be released from the winding wheel 11. The other end of the first steel cable 701 moves downward synchronously with the first slider 3. The steel cable is in a free and relaxed state. The tension control elastic element 8 in the compressed state inside the first slider 3 will rebound under its own characteristics, so that the steel cable is in close contact with the winding wheel 11 and the pulley, preventing the steel cable from derailing or climbing, and ensuring its smooth operation.
[0055] In summary, during different stages of glass lifting, the tension control elastic element 8 (specifically a high-carbon steel spring) can automatically extend and retract according to changes in cable tension (the pulling force applied to the slider), always applying a certain elastic force to the cable to maintain appropriate tension and ensure smooth and stable glass lifting. This further effectively prevents the other end of the cable in the first limiting groove 5 from slipping out of the groove or climbing out of the winding wheel 11 due to improper tension control, preventing the cable from deviating from the preset track direction. Furthermore, the inner diameter of the second channel 502 is larger than that of the first channel 501, ensuring that the tension control elastic element 8 will not slip into the first channel 501 when subjected to the tension of the cable. The bottom end of the tension control elastic element 8 (the end furthest from the stabilizing plate 9) can be stably positioned at the junction of the first channel 501 and the second channel 502.
[0056] In summary, the tubeless steel cable in this embodiment solves the problem of wear and tear on traditional steel cables caused by the sleeve. This embodiment also ensures that the steel cable does not deviate from the preset track direction after the sleeve is removed, and at the same time, it ensures that the steel cable has a certain "elastic force" to cope with the tension changes during the glass lifting process. Moreover, it is an integrated double guide rail, which reduces production costs and improves production efficiency.
[0057] In a preferred embodiment, the first limiting groove 5 and the second limiting groove 6 in the first slider 12 extend from the first slider 12 toward the slide rail 2 and extend to the bottom of the first slider 3.
[0058] The first limiting groove 5 and the second limiting groove 6 in the second slider 4 extend from the second slider 4 toward the slide rail 2 and extend to the bottom of the second slider 4.
[0059] In a preferred embodiment, the tension control elastic element 8 includes a high-carbon steel spring; the tension control elastic element 8 has a certain degree of contraction in the compressed state, and after contraction, it can make the steel cable have a certain degree of tightness, so as to prevent the steel cable from derailing or climbing in the winding wheel.
[0060] In a preferred embodiment, a piston 10 is provided at the bottom of the stabilizing plate 9, extending into the tension control elastic element 8; the end of the steel cable in the first limiting groove 5 is connected to the piston 10 (any connection method is acceptable and is within the scope of this application). This enhances the stability between the stabilizing plate 9 and the tension control elastic element 8.
