[0002] With the development of science and technology, the technology of new energy vehicles has become very mature, and therefore it has been widely promoted and used, and has been recognized by the market. The number of electric vehicles is increasing rapidly, and the growth of electric vehicles also requires matching and setting up charging devices to ensure the range of electric vehicles.

[0003] When using the charging device, the charging head needs to be unplugged from the charging device and then moved to the charging port of the electric vehicle to connect to the charging port. During the movement of the charging head, the cable connected to the charging head in the charging device will be dragged, causing the cable to move on the ground. Since the ground is relatively rough, the cable will be damaged due to friction when dragged on the ground. In addition, the cable is also easy to be stepped on on the ground. Another point is that the cable is long and can easily trip the driver or be run over by the electric vehicle when it is piled up on the ground, affecting daily use.

[0004] Therefore, how to provide an electric vehicle charging device is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0008] The translation component has more than two sets of transverse guide rods, with each set of transverse guide rods corresponding to one transverse block. The transverse guide rods, which have more than two sets, are arranged in parallel to each other.

[0009] The telescopic assembly includes a fixed disk, a rotating disk, a side gear disk, an annular gear, a through groove, a transmission gear, a lead screw, a movable block, a through hole, a drive motor, and a drive gear. The fixed disk is fixedly connected to the bottom of the transverse block on a set of transverse guide rods. The rotating disk is rotatably sleeved on the side of the fixed disk via bearings. The side gear disk is fixedly sleeved on the side of the rotating disk. The annular gear is fixedly connected to the bottom of the fixed disk.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] refer to Figure 1-6 In this embodiment, a charging pile body 1 and a charging head 2 are included. The top of the charging pile body 1 is provided with a canopy 3, which can provide shade and rain protection. A cable movement system is provided on the lower surface of the canopy 3. A cable body 4 is provided on the top of the charging pile body 1. The surface of the cable body 4 is located at the bottom of the cable movement system, and the end of the cable body 4 away from the charging pile body 1 is fixedly connected to the end face of the charging head 2. The cable movement system realizes the function of suspending and moving the cable body 4. In this way, the cable body 4 can be suspended to avoid dragging on the ground during use and causing damage to the cable body 4, and also to avoid being stepped on, run over or tripped by the car owner on the ground.

[0024] The cable movement system includes a translation component 5 and a telescopic component 6. The translation component 5 is located at the bottom of the ceiling 3, and the telescopic component 6 is located at the bottom of the translation component 5 near the outermost position. The translation component 5 includes a first transverse guide groove 7, a movable seat 8, a transverse guide rod 9, a second transverse guide groove 10, and a transverse block 11. The first transverse guide groove 7 is opened on the lower surface of the ceiling 3. The movable seat 8 is movably connected to the inside of the first transverse guide groove 7. The transverse guide rod 9 is fixedly connected to the bottom of the movable seat 8. The second transverse guide groove 10 is opened at the bottom of the transverse guide rod 9. The transverse block 11 is movably connected to the inside of the second transverse guide groove 10. The bottom end of the transverse block 11 extends out of the second transverse guide groove 10. The surface of the cable body 4 is fixedly connected to the bottom end of the transverse block 11.

[0025] In practice, the cable body 4 is connected to the transverse block 11. When in use, the charging head 2 is moved, and the charging head 2 will pull the transverse guide rod 9 through the telescopic component 6. The transverse guide rod 9 moves in the first transverse guide groove 7 through the movable seat 8. In this way, the transverse guide rod 9 is pulled and moved, which will drive the cable body 4 to move, thereby moving the cable body 4 to the appropriate position.

[0026] refer to Figure 1-6 In this embodiment, the translation component 5 has more than two sets of transverse guide rods 9, with each set of transverse guide rods 9 corresponding to one transverse block 11. The transverse guide rods 9, which are more than two sets in number, are arranged parallel to each other. This facilitates the segmented control of the cable body 4. Figure 2 As shown, the cable body 4 is designed for easy unfolding and retraction.

[0027] refer to Figure 1-6 In this embodiment, the transverse block 11 includes a movable sleeve block 23 and a rotating block 24. The movable sleeve block 23 is movably connected inside the second transverse guide groove 10, and the rotating block 24 is rotatably connected inside the movable sleeve block 23 through a tapered bearing.

[0028] In practice, the cable body 4 will extend or fold when pulled, and the cable body 4 will move when it extends or folds. The extension or folding of the cable body 4 will drive the rotating block 24 to rotate within the moving sleeve block 23, thus avoiding the cable body 4 from being subjected to torque after moving and affecting its normal use. When the cable body 4 is pulled, the cable body 4 moves within the second transverse guide groove 10 through the rotating block 24, thereby improving the freedom of movement of the hoisted cable body 4.

[0029] refer to Figure 1-6In this embodiment, the telescopic assembly 6 includes a fixed disk 12, a rotating disk 13, a side gear disk 14, an annular gear 15, a through groove 16, a transmission gear 17, a lead screw 18, a movable block 19, a through hole 20, a drive motor 21, and a drive gear 22. The fixed disk 12 is fixedly connected to the bottom of the transverse block 11 on a set of transverse guide rods 9. The rotating disk 13 is rotatably sleeved on the side of the fixed disk 12 via bearings. The side gear disk 14 is fixedly sleeved on the side of the rotating disk 13. The annular gear 15 is fixedly connected to the bottom of the fixed disk 12. The through groove 16 is formed on the lower surface of the rotating disk 13, connecting the lower and upper surfaces of the rotating disk 13. The lead screw 18 is rotatably connected inside the through groove 16. The transmission gear 17 is fixedly sleeved on the surface of the lead screw 18. Gear 17 meshes with ring gear 15. Movable block 19 is movably sleeved on the surface of lead screw 18 and slidably connected inside through slot 16. Through hole 20 is opened on the lower surface of movable block 19 to connect movable block 19. Drive motor 21 is fixedly connected to the side of fixed disk 12. Drive gear 22 is fixedly connected to the output shaft end of drive motor 21 and meshes with side gear disk 14. The end of cable body 4 away from charging pile body 1 extends from the top of fixed disk 12 to the inside of fixed disk 12 and is coiled inside fixed disk 12. The end of cable body away from charging pile body 1 extends from the inside of fixed disk 12 through through hole 20 and extends to the bottom of movable block 19 and is fixedly connected to the top of charging head 2.

[0030] In practice, when charging is required, the drive motor 21 must first be started via the charging pile body 1. The drive motor 21 is connected to the charging pile body 1 via wires and its start and stop are controlled by the charging pile body 1. The rotation of the drive motor 21 is adjusted according to the actual situation. After the drive motor 21 starts, it will drive the side gear disk 14 to rotate. The rotation of the side gear disk 14 will drive the rotating disk 13 to rotate on the fixed disk 12. The rotation of the rotating disk 13 will drive the lead screw 18 and the transmission gear 17 to move through the through groove 16. Since the transmission gear 17 moves while the ring gear 15 does not move, the movement of the transmission gear 17 will drive the ring gear 15 to rotate. During the movement of the transmission gear 17, the rotation will drive the lead screw 18 to rotate. The rotation of the lead screw 18 will drive the movable block 19 to move along the through groove 16 and the lead screw 18. The movement of the movable block 19 will drive the through hole 20. As the movable block 19 moves toward the center of the fixed plate 12, the cable body 4 releases its coiled ...

[0031] In summary, the cable body 4 was hoisted to avoid being stepped on, damaged by friction with the ground, run over, or tripped by drivers.

[0032] refer to Figure 1-6 In this embodiment, a guide groove is provided on the inner wall of the through groove 16, and the end face of the movable block 19 is movably connected to the inside of the guide groove.

[0033] The guide groove here is designed to improve the stability of the movable block 19 and prevent it from becoming unstable and stuck inside the through groove 16. This limits the movement of the movable block 19, allowing it to move stably along the lead screw 18 and the through groove 16.

[0034] The method of using this utility model is as follows:

[0035] During charging, first operate the charging pile body 1 to start the drive motor 21. The drive motor 21 drives the rotating disk 13 to rotate through the side gear disk 14. The rotating disk 13 drives the transmission gear 17 to rotate. The rotation of the transmission gear 17 drives the lead screw 18 to rotate. The rotation of the lead screw 18 will drive the through hole 20 to move through the movable block 19. The movement of the through hole 20 will release the coiled cable body 4. The cable body 4 extends downward, which will drive the charging head 2 to the position where the car owner can reach it. Then the car owner moves the charging head 2, which will drive the telescopic component 6 and the translation component 5 to move through the cable. This will move the cable body 4 to the appropriate position. The cable body 4 will continue to extend, which will bring the charging head 2 to the position of the electric vehicle charging port. Then the car owner can operate the charging head 2 to connect to the charging port to charge.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
