Description

Technical Field

[0001] This utility model relates to the field of electric vehicle technology, and in particular to an easily detachable electric vehicle window regulator. Background Technology

[0002] Car windows are an important part of the entire vehicle body. They are designed to meet the needs of interior lighting, ventilation, and the visibility of drivers and passengers. Car windows are classified according to their glass installation position: front and rear windshields, side windows, and door windows. To meet these needs, most side windows can be raised and lowered, and the raising and lowering process is controlled by a window regulator.

[0003] The rope pulley electric window regulator is a type of window regulator. During installation, the window glass is fixed on the glass mounting bracket, and the glass guide channel is parallel to the steel wire rope guide plate. When the glass is raised or lowered, the motor is started to output power. Using the drive component and guide component, the steel wire rope is pulled to drive the glass mounting bracket to move, thereby making the window glass move up and down in a straight line.

[0004] Most existing electric window regulators with rope pulleys rely solely on a motor for stroke control. The motor controls the number of rotations based on preset parameters, thus controlling the window's lifting stroke. However, a malfunction in the motor control system can cause the glass to move beyond its limits, leading to collisions between the glass and window components, resulting in damage to the object and potential injury from broken glass fragments. Utility Model Content

[0005] To overcome the problem that most electric window regulators with rope pulleys rely solely on motors for stroke control, which control the number of rotations based on preset parameters to regulate the window's lifting stroke, it's important to understand that a malfunction in the motor control system can cause the glass to move beyond its limits, leading to collisions between the glass and window components, resulting in damage and potential injury from broken glass fragments.

[0006] The technical solution of this utility model is as follows: an easy-to-disassemble electric window regulator, including a slide rail, a gear ring, and a drive assembly. A slide plate for mounting and fixing a glass panel is provided on the inner side of the slide rail, and the slide rail and the slide plate are slidably connected. A mounting housing is provided on one side of the slide rail, and a drive wheel is provided on the inner side of the mounting housing. The drive wheel is rotatably connected to the slide rail. A pull rope is wound around the outer side of the drive wheel and is fixedly connected to the slide plate. A drive assembly is provided on the inner side of the mounting housing, and a gear is provided on the inner side of the mounting housing. A gear ring is provided on the outer side of the gear, and the diameter of the gear ring is much larger than the diameter of the gear. The gear and the gear ring mesh with each other. A first limiting block is fixedly connected to the inner side of the mounting housing, and a second limiting block is fixedly connected to the outer side of the gear ring.

[0007] Preferably, guide wheels are provided at both ends of the slide, and sleeves are provided between the guide wheels and the mounting housing, with the pull rope slidably connected to the sleeves.

[0008] Preferably, the two ends of the skateboard are provided with fixing seats at the connection points with the pull rope, a deformation block is provided on one side of the fixing seat, a screw cap is provided on the outside of the deformation block, and a connecting seat is provided at the connection point of the pull rope. The connecting seat is composed of two sets of fixing seats.

[0009] Preferably, the deformable block is conical, has a deformation groove, is threaded to the cap, and has anti-slip texture on the outside of the cap.

[0010] Preferably, the drive assembly includes a drive motor and a worm gear. The drive motor is located on one side of the mounting housing, and the worm gear is located at the output end of the drive motor. The mounting housing has a first chamber, a second chamber, and a third chamber, with the worm gear located inside the second chamber.

[0011] Preferably, a connecting shaft is provided at the axis of the drive wheel, the connecting shaft is rotatably connected to the mounting housing, and a worm gear is provided on the outside of the second chamber portion of the connecting shaft, the worm gear meshing with the worm.

[0012] Preferably, the first limiting block, the second limiting block, the gear, and the gear ring are located inside the rotating shaft, and the rotating shaft is provided on one side of the gear ring. The rotating shaft is rotatably connected to the mounting housing.

[0013] The beneficial effects of this utility model are:

[0014] By setting a first limit block and a second limit block, the movement stroke of the glass panel is limited. When the glass is raised or lowered, the drive assembly drives the drive wheel to rotate and uses a pull rope to pull the slide plate to slide in the slide. The drive wheel and the gear rotate synchronously. The rotating gear will drive the gear ring to rotate. When the first limit block contacts the second limit block, the gear ring can no longer rotate, thereby stopping the rotation of the gear ring, gear and drive wheel to limit the movement stroke of the glass and prevent the glass from moving beyond the limit.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-5 This utility model provides an embodiment of an easily detachable electric window regulator, comprising a slide rail 1, a gear ring 9, and a drive assembly. The inner side of the slide rail 1 is provided with a sliding plate 2 for mounting and fixing a glass panel. The slide rail 1 and the sliding plate 2 are slidably connected. A mounting housing 4 is provided on one side of the slide rail 1. A drive wheel 5 is provided on the inner side of the mounting housing 4 and is rotatably connected to the slide rail 1. A pull rope 3 is wound around the outer side of the drive wheel 5 and is fixedly connected to the sliding plate 2. The drive assembly is provided on the inner side of the mounting housing 4, and a gear 8 is provided on the inner side of the mounting housing 4. A gear ring 9 is provided on the outer side of the gear 8. The diameter of the gear ring 9 is much larger than the diameter of the gear 8, and the gear 8 and the gear ring 9 mesh with each other. A first limiting block 404 is fixedly connected to the inner side of the mounting housing 4, and a second limiting block 901 is fixedly connected to the outer side of the gear ring 9. By setting the first limiting block 404 and the second limiting block 901, the movement stroke of the glass panel is limited. When the glass is raised or lowered, the drive assembly drives the drive wheel 5 to rotate and uses the pull rope 3 to pull the slide plate 2 to slide in the slide rail 1. The drive wheel 5 rotates synchronously with the gear 8. The rotating gear 8 will drive the gear ring 9 to rotate. When the first limiting block 404 contacts the second limiting block 901, the gear ring 9 can no longer rotate, thereby stopping the rotation of the gear ring 9, the gear 8 and the drive wheel 5 to limit the movement stroke of the glass and prevent the glass from moving beyond the limit.

[0023] Please see Figure 1 In this embodiment, guide wheels 301 are provided at both ends of the slide 1, and sleeves 302 are provided between the guide wheels 301 and the mounting housing 4. The pull rope 3 is slidably connected to the sleeves 302. The guide wheels 301 guide the direction of the pull rope 3, and the sleeves 302 protect the pull rope 3.

[0024] Please see Figure 2In this embodiment, a fixing seat 306 is provided at the connection points between the two ends of the slide plate 2 and the pull rope 3. A deformable block 304 is provided on one side of the fixing seat 306, and a cap 305 is provided on the outer side of the deformable block 304. A connecting seat 303 is provided at the connection point of the pull rope 3. The connecting seat 303 is formed by combining and fixing two sets of fixing seats 306. The deformable block 304 is conical and has a deformation groove. The deformable block 304 is threadedly connected to the cap 305. The outer side of the cap 305 is provided with anti-slip texture. When the cap 305 rotates on the outer side of the deformable block 304, it causes the deformable block 304 to deform and move closer to each other, clamping the pull rope 3 and fixing the deformable block 304 to the pull rope 3. When the fixing seats 306 at both ends of the slide plate 2 are fixed to the pull rope 3, the slide plate 2 is clamped between the two sets of fixing seats 306, thus connecting and fixing the slide plate 2 to the pull rope 3. When the connecting seat 303 is connected and fixed to the pull rope 3, the two ends of the pull rope 3 are connected and fixed.

[0025] Please see Figures 3-5 In this embodiment, the drive assembly includes a drive motor 6 and a worm gear 601. The drive motor 6 is located on one side of the mounting housing 4, and the worm gear 601 is located at the output end of the drive motor 6. The mounting housing 4 has a first chamber 401, a second chamber 402, and a third chamber 403. The worm gear 601 is located inside the second chamber 402. A connecting shaft 7 is located at the axis of the drive wheel 5, and the connecting shaft 7 is rotatably connected to the mounting housing 4. A worm wheel 602 is located on the outer side of the connecting shaft 7 in the second chamber 402, and the worm wheel 602 is connected to the worm gear 601. The components are intermeshing. The first limiting block 404, the second limiting block 901, the gear 8, and the gear ring 9 are located inside the rotating shaft 902. The rotating shaft 902 is provided on one side of the gear ring 9 and is rotatably connected to the mounting housing 4. The drive motor 6 drives the worm 601 to rotate and drives the worm wheel 602 to rotate, thereby driving the connecting shaft 7 to rotate and driving the drive wheel 5 and the gear 8 to rotate. The first chamber 401, the second chamber 402, and the third chamber 403 partition and install different components to prevent interference. The rotating shaft 902 rotatably connects the gear ring 9 to the mounting housing 4.

[0026] When the glass is raised or lowered, the drive motor 6 drives the worm gear 601 to rotate and drives the worm wheel 602 to rotate, thereby driving the connecting shaft 7 to rotate and driving the drive wheel 5 and gear 8 to rotate. The drive wheel 5 rotates and uses the pull rope 3 to pull the slide plate 2 to slide in the slide rail 1, thereby raising or lowering the glass. The drive wheel 5 and gear 8 rotate synchronously. The rotating gear 8 will drive the gear ring 9 to rotate. When the first limit block 404 contacts the second limit block 901, the gear ring 9 can no longer rotate, thereby stopping the rotation of the gear ring 9, gear 8 and drive wheel 5 to limit the movement of the glass and prevent the glass from moving beyond the limit.

[0027] When the screw cap 305 rotates outside the deformable block 304, it causes the deformable block 304 to deform and move closer to each other, clamping the pull rope 3 and thus fixing the deformable block 304 and the pull rope 3. When the fixing seats 306 at both ends of the slide plate 2 are fixed to the pull rope 3, the slide plate 2 is clamped between the two sets of fixing seats 306, thus connecting and fixing the slide plate 2 and the pull rope 3. When the connecting seat 303 is connected and fixed to the pull rope 3, the two ends of the pull rope 3 are connected and fixed. This fixing method makes it easy to disassemble and assemble the pull rope 3, and makes it convenient to replace the pull rope 3 when it is worn.

[0028] Through the above steps, the movement stroke of the glass panel is limited by setting the first limiting block 404 and the second limiting block 901. When the glass is raised or lowered, the drive assembly drives the drive wheel 5 to rotate and uses the pull rope 3 to pull the slide plate 2 to slide in the slide rail 1. The drive wheel 5 rotates synchronously with the gear 8. The rotating gear 8 will drive the gear ring 9 to rotate. When the first limiting block 404 contacts the second limiting block 901, the gear ring 9 can no longer rotate, thereby stopping the rotation of the gear ring 9, the gear 8 and the drive wheel 5 to limit the movement stroke of the glass and prevent the glass from moving beyond the limit.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
