Technical Field

[0001] This utility model relates to the field of charging gun technology, specifically to an automatic anti-tangling and retracting device for charging gun cables. Background Technology

[0002] New energy vehicles are powered by batteries, replacing the traditional fuel engines, which is more environmentally friendly and saves costs. After the energy inside the car is exhausted, it is necessary to find a charging station and plug the charging gun into the car's charging port to replenish the power. Both the gun and the charging port are equipped with magnetic attraction to prevent them from falling off.

[0003] Since cars are parked in various locations, charging harnesses are usually quite long to enhance their versatility. To prevent the harnesses from being dragged around, an anti-tangling take-up and take-down device is needed to store them. When pulling out the harness and charging gun, the cables should be organized simultaneously. Previous automatic take-up and take-down devices lacked restrictions. If the rollers deviate during rotation, they can easily jam, affecting the subsequent pulling out and winding of the harness.

[0004] Now, a novel automatic anti-tangling and retraction device for charging gun cables is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an automatic anti-tangling and rewinding device for charging gun cables, in order to solve the problem of easy jamming of the rotating roller mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic anti-tangling and rewinding device for charging gun cables, comprising a housing and a rotating roller. The rotating roller is movably connected at the center between the top and bottom ends inside the housing, and a coil spring is installed between the rotating roller and the housing. A rotating disk is fixed at the top and bottom ends outside the rotating roller, and ball bearings are movably embedded in the interior of both sides of the rotating disk. Limiting disks are horizontally welded to the upper and lower sides of the inner wall of the housing, and a groove is provided around the inside of the limiting disk. A back plate is fixed at the rear of the housing. A wire harness is wound around the surface of the rotating roller, and a connector is movably connected at the center of the top end of the housing.

[0007] Preferably, the bottom of the connector is fixedly connected to the wire harness, and the rotating disk is symmetrically fixed at the top and bottom of the outside of the rotating roller.

[0008] Preferably, the side of the ball fits into the groove, and the disc rotates horizontally within the limiting plate.

[0009] Preferably, a vertical groove is longitudinally provided inside the left side of the outer casing, and a worm gear is movably connected between the upper and lower parts inside the vertical groove. Worm wheels are movably connected between the upper and lower sides inside the vertical groove. Threaded cylinders are movably connected between the upper and lower parts inside the left side of the outer casing, and a screw is threadedly connected to the threaded cylinder. A sleeve block is fixed to the right side of the screw, and a sleeve shell is longitudinally fixed at the center between the sleeve blocks. A roller shaft is movably connected between the upper and lower parts inside the sleeve shell. A motor is fixed to the upper left corner inside the outer casing.

[0010] Preferably, the bottom of the motor's output end is fixedly connected to the worm gear, and the worm gear is meshed with the rear of two sets of worm wheels.

[0011] Preferably, the right side of the worm gear is fixedly connected to the threaded cylinder, and the roller rotates longitudinally inside the casing.

[0012] Preferably, a slot is provided at the lower right corner of the outer shell, the wire harness is embedded in the slot, a charging gun is fixed to the end of the wire harness, a box is fixed to the right side of the outer shell, and a sleeve is fixed between the two sides inside the box. A slot is provided at the center of the bottom of the box. A dustproof plate is hinged to the right side of the front end of the box, and magnetic suction pieces are fixed at the top and bottom of the right side of the front end of the dustproof plate.

[0013] Preferably, the charging gun is embedded between the card sleeve and the card slot, and the dustproof plate is rotated and attached to the surface of the box.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the automatic anti-tangling and rewinding device for charging gun cables not only maintains the stability of the rotating roller and the flatness of the cable bundle, but also protects the charging gun;

[0015] (1) By fixing a rotating disk at the top and bottom of the outside of the rotating roller, the rotating roller is installed inside the outer shell by the coil springs at the top and bottom. The wire harness connected to the charging gun will pass through the slot. The rotating disk on the surface of the rotating roller will roll along the groove by the ball bearings on both sides. The rotation of the rotating disk and the rotating roller is restricted at the limiting plate to maintain the balance of the object and prevent it from jamming. The top of the wire harness passes through the rotating roller and is fixed to the connector, so that it can connect to the external wire harness and transmit current.

[0016] (2) By connecting the roller shaft between the upper and lower parts inside the casing, when the coil spring guides the rotating roller to rotate, or when the rotating roller rotates due to the pulling effect of the wire harness, the motor can be turned on and the rotating worm can push the worm wheel with the rotating worm, guiding the threaded cylinder to push out the internal screw at the same time, forcing the casing that is longitudinally fixed between the sleeve blocks to move left and right. At this time, the roller shaft will be attached to the left side of the wire harness, and the auxiliary wire harness will be neatly wound on the rotating roller.

[0017] (3) A charging gun is fixed to the end of the wire harness. The wire harness passes through the slot and the charging gun is embedded in the box. It is fixed by a card sleeve. The wire harness is also embedded in the card slot. After the charging gun finishes charging, it can be placed inside the box for protection. After closing the dustproof plate, the magnetic strip on its surface makes the dustproof plate stick to the surface of the box, which is also easy to open. Attached Figure Description

[0025] The bottom of connector 2 is fixedly connected to wire harness 13. Rotary disc 12 is symmetrically fixed at the top and bottom of the outside of rotary roller 3. The side of ball 14 fits into groove 20. Rotary disc 12 rotates horizontally in limiting disc 11.

[0026] Specifically, such as Figure 1 and Figure 2 As shown, the rotating roller 3 is installed inside the outer casing 1 by coil springs 15 at both the top and bottom. The wire harness 13 connected to the charging gun 19 is pulled through the slot 26. The rotating disk 12 on the surface of the rotating roller 3 rolls against the groove 20 by the ball bearings 14 on both sides. The rotation of the rotating disk 12 and the rotating roller 3 is restricted at the limiting plate 11 to maintain the balance of the object and prevent it from jamming.

[0027] A vertical groove 6 is longitudinally arranged inside the left side of the outer casing 1, and a worm gear 8 is movably connected between the upper and lower parts inside the vertical groove 6. Worm wheels 7 are movably connected between the upper and lower sides inside the vertical groove 6. A threaded cylinder 9 is movably connected between the upper and lower parts inside the left side of the outer casing 1, and a screw 10 is threadedly connected in the threaded cylinder 9. A sleeve block 25 is fixed to the right side of the screw 10, and a sleeve shell 21 is longitudinally fixed at the center between the sleeve blocks 25. A roller shaft 22 is movably connected between the upper and lower parts inside the sleeve shell 21. A motor 5 is fixed in the upper left corner inside the outer casing 1.

[0028] The bottom of the output end of the motor 5 is fixedly connected to the worm 8. The worm 8 is meshed with the rear of the two sets of worm wheels 7. The right side of the worm wheel 7 is fixedly connected to the threaded cylinder 9. The roller 22 rotates longitudinally inside the casing 21.

[0029] Specifically, such as Figure 1 and Figure 3 As shown, when the coil spring 15 guides the rotating roller 3 to rotate, or when the rotating roller 3 is pulled by the wire harness 13, the motor 5 can be turned on and the rotating worm 8 can push the worm wheel 7 to guide the threaded cylinder 9 to push out the internal screw 10 laterally, forcing the sleeve 21, which is fixed longitudinally between the sleeve blocks 25, to move left and right. At this time, the roller shaft 22 will be attached to the left side of the wire harness 13 to tidy up the wound wire harness 13.

[0030] A slot 26 is provided at the lower right corner of the outer shell 1. The wire harness 13 is embedded in the slot 26. A charging gun 19 is fixed to the end of the wire harness 13.

[0032] Working principle: In use, the rotating roller 3 is installed inside the outer casing 1 via coil springs 15 at both the top and bottom. Pulling out the charging gun 19 causes the wiring harness 13 connected to it to pass through the slot 26. The rotating disc 12 on the surface of the rotating roller 3 rolls against the groove 20 via ball bearings 14 on both sides. The rotation of the disc 12 and the rotating roller 3 is restricted at the limiting plate 11, maintaining the balance of the device and preventing jamming. The top of the wiring harness 13 passes through the rotating roller 3 and is fixed to the connector 2. The wiring harness 13 passes through the slot 26, and the charging gun 19 is embedded in the housing 16 and secured by the retaining sleeve 18. 3 is also embedded in the slot 23. After the charging gun 19 finishes charging, it can be placed inside the box 16 for protection. After the dustproof plate 17 is closed, the charging gun 19 is protected. When the coil spring 15 guides the rotating roller 3 to rotate, or when the rotating roller 3 is rotated due to the pulling effect of the wire harness 13, the motor 5 can be turned on and the worm wheel 7 can be pushed by the rotating worm 8. The threaded cylinder 9 is guided to push out the internal screw 10 laterally, which forces the sleeve 21, which is fixed longitudinally between the sleeve blocks 25, to move left and right. At this time, the roller shaft 22 will be attached to the left side of the wire harness 13, and the auxiliary wire harness 13 is neatly wound on the rotating roller 3.
