Description

A new energy vehicle window regulator Technical Field

[0001] This invention relates to the field of automotive glass components technology, specifically to a window regulator for new energy vehicles. Background Technology

[0002] The basic principle of automotive window regulators is that an electric motor drives a reducer to output power, which pulls a steel wire rope to move the glass mounting bracket, forcing the window glass to move in a straight line. This type of mechanism has the advantages of good flexibility, high strength, and impact resistance, which can ensure smooth operation of the mechanism, low resistance, and long service life.

[0003] However, in actual use, the repeated pulling of the steel wire rope causes it to deform under stress and become longer. Since the steel wire rope needs to be wound around the winch, once the steel wire rope is stretched, it will inevitably become loose, causing slippage between the winch and the steel wire rope. At the same time, because the steel wire rope is longer, the glass mounting bracket that is pulled by the steel wire rope will also become loose, which in turn leads to instability of the car glass. Summary of the Invention

[0004] To address this issue, the present invention provides a new energy vehicle window regulator that can automatically tighten the steel wire rope to solve the problem of slippage between the winch and the steel wire rope caused by deformation of the steel wire rope in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This invention discloses a window regulator for new energy vehicles, comprising:

[0007] An electric drive unit, the power output end of which is coaxially connected to a self-tightening winch, the self-tightening winch having a traction cable wound around it, the traction cable being connected end to end;

[0008] Each of the two guide members has a fixed pulley at one end. The traction cable passes through all four fixed pulleys simultaneously and slides within the two guide members.

[0009] A lifting assembly is fixedly connected to the traction cable and adapted to slide along the guide member;

[0010] The lifting assembly includes a glass bracket and a limit switch. The limit switch is installed at the bottom of the glass bracket, and the top of the glass bracket is fixed to the car glass. The traction cable drags the glass bracket to move along the guide.

[0011] When the limit switch contacts the end of the guide member, the electric drive device stops operating; when the car window is completely closed, the outer diameter of the self-tightening winch of the electric drive device expands to tighten the traction cable.

[0012] Furthermore, the electric drive device includes:

[0013] The motor's output end is connected to the power input end of the reducer, and the reducer's power output end is coaxially connected to the self-tightening winch.

[0014] The comb base has a self-tightening winch rotatably mounted inside, and its top is screwed to the housing of the reducer.

[0015] Furthermore, the comb base includes:

[0016] The base has a winch groove in the middle, and the self-tightening winch is rotatably disposed in the winch groove.

[0017] The conductor groove is connected to the winch groove in the middle and has spring cable sleeves installed at both ends.

[0018] The traction cable is wound around a self-tightening winch via a spring cable loop and is adapted to slide along the guide groove.

[0019] Furthermore, the self-tightening winch includes:

[0020] A limiting wheel hub has several tire expansion components inserted circumferentially along its outer edge, and any one of the tire expansion components is suitable for sliding along the radial direction of the wheel hub.

[0021] The support assembly has several connecting rods that are circumferentially hinged together. Each of the connecting rods corresponds to one of the several expansion tire components and is hinged to the corresponding expansion tire components.

[0022] The double-ended screw has a ratchet in the middle, which is adapted to abut against the pawl mounted on the limiting hub. The end is fitted with a support component and is coaxially connected to the electric drive device.

[0023] Furthermore, the limiting hub includes:

[0024] The inner ring and outer edge are integrally provided with a number of guide spokes, and the guide spokes are provided with through grooves;

[0025] The pawl mounting positions are symmetrically arranged at both ends of the inner ring and are hinged to the pawls.

[0026] Furthermore, the tire expansion component includes:

[0027] An arc plate with a rod inserted on its inner side, the rod being slidably inserted into the through groove;

[0028] The first hinge position is located at the end of the arc plate and hinged to one end of the connecting rod;

[0029] A cable groove is provided on the outside of the arc plate and the traction cable is embedded therein.

[0030] Furthermore, the support component includes:

[0031] The nut is fitted onto the double-ended screw at its center and is threaded into the double-ended screw. Several friction limiting grooves are provided on its outer edge. The friction limiting grooves pass through the nut and communicate with the center hole of the nut.

[0032] The friction hinge seat has a rubber pad at its tail end, which is inserted into the friction limiting groove and is suitable for abutting against the double-ended screw. Its head end is hinged to the other end of the connecting rod.

[0033] Furthermore, the double-ended screw includes:

[0034] The screw is integrally formed with the ratchet in the middle, and has a pair of opposite threads at both ends;

[0035] A spline groove is provided at the end of the screw, which is suitable for insertion into the power output end of the electric drive device to transmit torque.

[0036] Furthermore, the arc plate, the insert rod, the inner ring, the guide spokes, and the through groove are all integrally formed using an aluminum alloy casting process.

[0037] Furthermore, the reducer is a worm gear reducer.

[0038] The present invention has the following advantages:

[0039] The automotive window regulator provided by this invention adopts a double-rail rope wheel design, which drives the glass bracket to move up and down through a traction cable. It has the advantages of simple structure, high flexibility, and good shock resistance. At the same time, this invention adds a self-tightening winch to the original design. When the self-tightening winch can drive the glass bracket to move by forward and reverse rotation, it can also tighten the traction cable by continuing to reverse the rotation when the glass bracket closes the car window. This solves the problem of slippage between the winch and the steel wire rope caused by deformation and elongation of the steel wire rope. Attached Figure Description

[0054] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0055] As shown in Figures 1-11, this invention discloses a new energy vehicle window regulator, installed inside the vehicle door, which moves the car window up and down. Its structure includes an electric drive unit 1, a guide component 3, and a lifting assembly 5. The device is described in detail below. First, the electric drive unit 1 is powered by the new energy vehicle battery. Simultaneously, the power output end of the electric drive unit 1 is coaxially connected to a self-tightening winch 6 to drive the winch 6 in both forward and reverse directions. Multiple turns of traction cable 2 are wound around the self-tightening winch 6, thereby generating sufficient static friction between the traction cable 2 and the self-tightening winch 6. The traction cable 2 is a steel cable with high tensile strength. The traction cable 2 is connected end-to-end and fixedly connected to a pair of lifting assemblies 5. The lifting assembly 5 is slidably mounted on the guide member 3. The guide member 3 is similar to a guide rail and mainly serves a guiding function. On this basis, a pair of lifting assemblies 5 are installed on two guide members 3. Each guide member 3 has a fixed pulley 4 at its end. The traction cable 2 can pass over four fixed pulleys 4 at the same time. When the traction cable 2 slides along the two guide members 3, the direction of the traction force can be changed through the fixed pulleys 4 so as to load a pair of lifting assemblies 5. In this embodiment, as shown in Figures 1 and 2, the lifting assembly 5 includes a glass bracket 51 and a limit switch 52. The glass bracket 51 is used to install automotive glass, and the bottom end of the glass bracket 51 is equipped with a limit switch 52. The limit switch 52 is electrically connected to the motor 11. Its function is that when the motor 11 drives the glass bracket 51 to move downward, the limit switch 52 can be triggered, thereby preventing the motor 11 from continuing to rotate and preventing damage to the glass bracket 51. In addition, the top of the glass bracket 51 is fixed to the car glass. When the traction cable 2 drags the glass bracket 51 upward along the guide 3, and when the car glass is completely closed, the electric drive unit 1 will continue to drive the self-tightening winch 6 to continue to rotate, and the outer diameter of the self-tightening winch 6 will expand to tighten the traction cable 2.

[0056] In this embodiment, as specifically described in Figure 3, the electric drive device 1 includes a motor 11 and a comb base 13. The output end of the motor 11 is connected to the power input end of the reducer 12 to increase the output power and drive the glass bracket 51 to move. The power output end of the reducer 12 is coaxially connected to the self-tightening winch 6 to drive the self-tightening winch 6 to rotate. It should be noted that the reducer 12 in this embodiment is a worm gear reducer. Since the reducer 12 adopts a unidirectional transmission method, it can control the rotation direction of the equipment while adjusting the speed, and can prevent reverse or inertial motion from damaging the equipment. In addition, the self-tightening winch 6 is rotatably disposed inside the comb base 13, and the top of the comb base 13 is screwed and fixed to the housing of the reducer 12 to protect the worm gear mechanism.

[0057] Based on the previous embodiment, as shown in Figure 4, the comb base 13 includes a base body 131 and a wire groove 133. The base body 131 is a casting. A winch groove 132 is provided in the middle of the base body 131. The self-tightening winch 6 is rotatably disposed in the winch groove 132. The winch groove 132 is located in the middle of the wire groove 133 and is connected to it, thereby allowing the traction cable 2 to move along the wire groove 133. At the same time, spring cable sleeves 134 are installed at both ends of the wire groove 133. The spring cable sleeves 134 can effectively wrap the traction cable 2, and the traction cable 2 is wound around the self-tightening winch 6 through the spring cable sleeves 134 and is suitable for sliding along the wire groove 133. This can prevent the traction cable 2 from contacting the outside, thereby protecting the traction cable 2.

[0058] In some embodiments, as shown in Figures 5 and 6, the self-tightening winch 6 includes a limiting hub 61, a support assembly 63, a double-ended screw 64, and expansion components 65. The limiting hub 61 is a cast part, and a plurality of expansion components 65 are evenly inserted into its outer side along the circumference. Any one of the expansion components 65 is adapted to slide radially along the hub 61, while a pawl 66 is provided on the inner side of the limiting hub 61. On the other hand, a double-ended screw 64 is provided at the center of the limiting hub 61, and a ratchet 67 is provided in the middle of the double-ended screw 64. The ratchet 67 is adapted to abut against the pawl 66 installed on the limiting hub 61, so that when the double-ended screw 64 rotates in the forward direction, it can drive the limiting hub 61 to rotate. A support assembly 63 is fitted at the end of the double-ended screw 64. Several connecting rods 62 are circumferentially hinged to the support assembly 63. Each connecting rod 62 corresponds to and is hinged to a corresponding tire-expanding component 65. Since the double-ended screw 64 is coaxially connected to the electric drive device 1, when the electric drive device 1 drives the double-ended screw 64 to rotate in the opposite direction, the support assembly 63 can push the tire-expanding component 65 outward through the connecting rods 62. This tightens the traction lock 2 wound around the tire-expanding component 65, thus solving the problem of the traction lock 2 becoming loose due to long-term pulling.

[0059] In this embodiment, as shown in Figure 11, the limiting hub 61 includes an inner ring 611 and a pawl mounting position 613. A plurality of guide spokes 612 are integrally formed along the outer edge of the inner ring 611. These guide spokes 612 are evenly arranged, and each guide spoke 612 has a through groove 614. The inner ring 611, through groove 614, and guide spokes 612 are all integrally formed using a casting process, resulting in high connection strength. The pawl mounting position 613 is symmetrically arranged at both ends of the inner ring 611 and hinged with pawls 66. A torsion spring is also provided at the connection between the pawl mounting position 613 and the pawl 66. The elastic force of the torsion spring drives the pawl 66 to reset, achieving a unidirectional rotation effect between the inner ring 611 and the ratchet 67.

[0060] In this embodiment, as shown in Figure 6, the tire expansion component 65 includes: an arc plate 651, a hinge position 653, and a cable groove 654. An insert rod 652 is provided on the inner side of the arc plate 651, and the insert rod 652 is slidably inserted into the through groove 614, thereby allowing the arc plate 651 to move along the direction of the insert rod 652. A hinge position 653 is provided at the end of the arc plate 651, and two hinge positions 653 can be symmetrically arranged at both ends of the arc plate 651. The hinge position 653 is hinged to one end of a connecting rod 62, and the other end of the connecting rod 62 is hinged to a support assembly 63. Therefore, when the support assembly 63 moves towards the limiting hub 61, the arc plate 651 can be expanded to achieve the effect of tightening the traction cable 2. Furthermore, a cable groove 654 is provided on the outer side of the arc plate 651, and the traction cable 2 is embedded in the cable groove 654 to prevent the traction cable 2 from loosening.

[0061] Specifically, as shown in Figures 7 and 8, and Figures 10 and 11, the double-ended screw 64 includes a screw 641 and a spline groove 643. The middle part of the screw 641 is integrally formed with the ratchet 67, and both ends are provided with a pair of oppositely rotating external threads 642. The end of the screw 641 is provided with a spline groove 643. The power output end of the electric drive device 1 is inserted into the spline groove 643 to transmit torque. Since the pair of oppositely rotating external threads 642 rotate in opposite directions, when the double-ended screw 64 reverses, the two nuts 631 sleeved at both ends of the screw 641 can be driven to move towards each other through the threaded transmission, thereby opening the arc plate 651.

[0062] Based on this, as shown in Figure 9, the support component 63 includes a nut 631 and a friction hinge seat 633. The nut 631 is provided with an internal thread that mates with the external thread 642. The center of the nut 631 is sleeved on the double-ended screw 64 and threadedly engaged with the double-ended screw 64. Several friction limiting grooves 632 are provided on the outer edge of the nut 631. The friction limiting grooves 632 pass through the nut 631 and communicate with the center hole of the nut 631. A friction hinge seat 633 is suitable for insertion into the friction limiting groove 632. A rubber pad 634 is provided at the tail of the friction hinge seat 633. When the double-ended screw 64 rotates in the opposite direction, the nut 631 moves towards the limiting hub 61. At the same time as the arc plate 651 opens, since the hinge seat 633 is inserted into the friction limiting groove 632 and is suitable for abutting against the double-ended screw 64, and its first end is hinged to the other end of the connecting rod 62, the hinge seat 633 can enter the nut 631 along the friction limiting groove 632. The rubber pad 634 abuts against the screw 641, generating friction between them. Simultaneously, since the traction cable is already taut, the arc plate 651 is restricted from further expansion, thus maintaining its stability. Furthermore, the friction between the rubber pad 634 and the screw 641 is further increased. Therefore, when the double-ended screw 64 reverses, the friction force can drive the limiting hub 61 to reverse, causing the lifting assembly 5 to move and achieving the technical effect of tautening the traction cable 2.

[0063] Although the present invention has been described in detail above with general descriptions and specific embodiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
