Description

Technical Field

[0001] The utility model relates to the technical field of charging piles, in particular to a charging pile with a wire storage function. Background Art

[0002] With the rapid development of the electric vehicle industry, the market demand for electric vehicle charging piles has increased rapidly. Charging piles are special equipment for charging electric vehicles. Generally, the charging pile host is connected to a charging cable, which is connected to a charging gun. When charging, the charging head is removed and inserted into the charging head of the electric vehicle. The charging cable is generally of a certain length. After the charging gun is hung back on the charging pile host, the excess length of the charging cable is easily stepped on or run over by people or cars on the ground. The prior art also discloses a charging cable storage mechanism for a charging pile. However, in order to prevent the charging cable from getting tangled, it uses a method of tightly winding the charging cable around a reel or pulley. Therefore, the curvature of the charging cable at the bend is small, and the charging cable is bent to a large extent, which increases fatigue damage to the charging cable and increases the resistance when the cable is pulled out. Utility Model Content

[0003] In response to the above-mentioned prior art, the present invention provides a charging pile with a wire storage function, which reduces the resistance of pulling out the charging wire and reduces fatigue damage to the charging wire.

[0004] To achieve the above-mentioned purpose, the technical solution of the embodiment of the utility model is implemented as follows:

[0005] A charging pile with a wire storage function includes a charging pile body, a wire storage mechanism and a control switch. The wire storage mechanism includes a plurality of slide rails, a movable pulley, a slider and an electric push rod. Each of the slide rails is slidably connected to two sliders. The slider is provided with the movable pulley. The movable pulley includes a first roller and a second roller. The first roller and the second roller are provided with a guide groove. The charging wire of the charging pile is S-shaped and passes through the guide groove between the first roller and the second roller in sequence. The electric push rod is used to push the slider up and down, and the electric push rod is electrically connected to the control switch.

[0006] Furthermore, a horizontal mounting frame is provided on the side of the slider, the first roller and the second roller are respectively connected to a U-frame, and the U-shaped frame is rotatably connected to the mounting frame.

[0007] Furthermore, a rotating shaft is provided in the middle of the U-shaped frame, and an axial hole is provided in the mounting frame, and the rotating shaft is rotatably connected to the axial hole.

[0008] Furthermore, the slider is provided with a protective cover, the front end and the rear end of the protective cover are provided with openings, and the side surface of the protective cover is spindle-shaped and smoothly transitions with the slider.

[0009] Furthermore, the slide rail is provided with a slide groove, the slider is slidably connected to the slider, a fixed block is provided in the middle of the slide rail, one end of the electric push rod is connected to the fixed block, and the other end is connected to the slider.

[0010] Furthermore, the wire storage mechanism is arranged on the side of the charging pile body, and the bottom of the charging pile body is provided with a base extending toward the side, and the slide rail is fixedly connected to the base.

[0011] Furthermore, the control switch is installed on the charging pile body.

[0012] Furthermore, the electric push rod is replaced by a lifting mechanism, which includes a screw, a first bevel gear, a second bevel gear and a motor. The output shaft of the motor is provided with the second bevel gear of the drag rod, and the screw is provided with the first bevel gear. The first bevel gear is engaged with the second bevel gear. The spiral rotation direction of the upper end of the screw is opposite to that of the lower end, and the screw and the slider are matched through threads.

[0013] The beneficial effects of the present invention are as follows: the charging cable is confined within the guide groove, so when storing the charging cable, it does not need to be tightened, which can reduce the degree of bending of the charging cable and effectively protect the charging cable. When releasing the charging cable, since the charging cable is not in a tightened state, the friction when pulling the charging cable out is also small, making it convenient to pull out the charging cable to charge the vehicle. Since the charging cable does not need to be tightened, the force required to overcome the bending of the charging cable is also reduced, and the force required by the electric push rod to push the slider to move is also reduced. At the same time, not needing to tighten the charging cable can also reduce fatigue damage to the charging cable. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Example 1

[0022] Refer to the attached Figure 1-2The present application provides a charging pile with a wire storage function, including a charging pile body 1, a wire storage mechanism 2 and a control switch 3. The charging wire 22 of the charging pile body 1 is stored by the wire storage mechanism 2 when not in use. The wire storage mechanism 2 includes a plurality of slide rails 4, a movable pulley, a slider 5 and an electric push rod 6. Each of the slide rails 4 is slidably connected to two of the sliders 5. The slider 5 can slide up and down along the slide rail 4. The slider 5 is provided with the movable pulley. The electric push rod 6 is used to push the slider 5 up and down. The electric push rod 6 is electrically connected to the control switch 3. The electric push rod 6 is connected and controlled by a control switch 3 to raise and lower the electric push rod 6. The movable pulley includes a first roller 7 and a second roller 8, each of which is provided with a guide groove 9. The charging cable 22 of the charging pile passes through the guide groove 9 between the first roller 7 and the second roller 8 in an S-shape. When the slider 5 is at the upper and lower ends of the slide rail 4, the movable pulley on the slider 5 pulls the charging cable 22 toward both ends, increasing the distance the charging cable 22 bypasses the S-shaped path and shortening the distance the charging cable 22 extends from the storage mechanism, allowing the charging cable 22 to be stored. When the distance between the two sliders 5 is shortened, the distance the charging cable 22 bypasses the S-shaped path is shortened, increasing the distance the charging cable 22 can extend from the storage mechanism, allowing the charging cable 22 to be pulled out to charge the vehicle. The charging cable 22 of the present utility model is confined within the guide groove 9. Therefore, when storing the charging cable 22, it does not need to be tightened, which can reduce the degree of bending of the charging cable 22 and effectively protect the charging cable 22. When releasing the charging cable 22, since the charging cable 22 is not in a tensioned state, the friction when pulling the charging cable 22 out is also low, making it easier to pull out the charging cable 22 to charge the vehicle. Since the charging cable 22 does not need to be tensioned, the force required to overcome the bending of the charging cable 22 is reduced, and the force required by the electric push rod 6 to push the slider 5 is also reduced. Furthermore, since the charging cable 22 does not need to be tensioned, fatigue damage to the charging cable 22 is reduced.

[0023] Specifically, a horizontal mounting bracket 10 is provided on the side of the slider 5. The first roller 7 and the second roller 8 are respectively connected to a U-shaped bracket 11, and the U-shaped bracket is rotatably connected to the mounting bracket 10. The first roller 7 and the second roller 8 can rotate. When the angle of the charging cable 22 changes, the angle of the first roller 7 and the second roller 8 also changes accordingly, thereby preventing the increase in friction caused by the change in the angle of the charging cable 22 and the wear of the charging cable 22 caused by the increased friction. The U-shaped bracket provides stable support for the first roller 7 and the second roller 8 from both sides.

[0024] Specifically, a rotating shaft 12 is provided in the middle of the U-shaped frame, and the mounting frame 10 is provided with an axial hole. The rotating shaft 12 is rotatably connected to the axial hole. The rotating shaft 12 passes through the axial hole. When the U-shaped rod rotates, the rotating shaft 12 can rotate accordingly, thereby ensuring that the first roller 7 and the second roller 8 rotate with the charging cable 22.

[0025] Example 2

[0026] Refer to the attached Figure 1-2 This embodiment differs from Embodiment 1 in that the slider 5 is provided with a protective cover 13 with openings 14 at the front and rear ends. The sides of the protective cover 13 are spindle-shaped and smoothly transition with the slider 5. The protective cover 13 prevents the slider 5 from getting stuck in the adjacent charging cable 22 during the raising and lowering process, ensuring stable operation of the charging cable 22 during storage and release. The front and rear openings 14 of the protective cover 13 ensure smooth entry and exit of the charging cable 22.

[0027] Specifically, the slide rail 4 is provided with a slot 15, with the slider 5 slidably connected thereto. A fixed block 16 is provided in the middle of the slide rail 4. One end of the electric push rod 6 is connected to the fixed block 16, and the other end is connected to the slider 5. When the electric push rod 6 above the fixed block 16 extends or contracts, it drives the slider 5 above it upward or downward. When the electric push rod 6 below the fixed block 16 extends or contracts, it drives the slider 5 above it downward or upward. Optionally, the electric push rod 6 is disposed within the slot 15, so that the surface of the slider 5 is flush with the surface of the slide rail 4, thereby preventing the slider 5 from being caught by the charging cable 22 during raising or lowering.

[0028] Specifically, the wire storage mechanism 2 is provided on the side of the charging pile body 1. The bottom of the charging pile body 1 is provided with a base 17 extending laterally. The slide rail 4 is fixedly connected to the base 17. The base 17 provides support for the slide rail 4. The height of the slide rail 4 is the same as the height of the charging pile. When the slider 5 moves toward the middle, the length of the charging cable 22 can be released.

[0029] Specifically, the control switch 3 is installed on the charging pile body 1 for easy control.

[0030] Example 3

[0031] Refer to the attached Figure 3The difference between this embodiment and embodiment 1 is that the electric push rod 6 is replaced by a lifting mechanism, which includes a screw 18, a first bevel gear 19, a second bevel gear 21, and a motor 20. The output shaft of the motor 20 is provided with the second bevel gear 21, and the screw 18 is provided with the first bevel gear 19. The first bevel gear 19 meshes with the second bevel gear 21. The helical rotation direction of the upper end of the screw 18 is opposite to that of the lower end. The screw 18 and the slider 5 are engaged by a thread. When the motor 20 rotates, the second bevel gear 21 rotates, and the second bevel gear 21 rotates the screw 18. When the screw 18 rotates, it drives the sliders 5 to move toward the center or away from the sides. The motor 20 drives multiple sliders 5 to move simultaneously, resulting in a simple structure.
