[0024] The present invention proposes a charging cable storage device for new energy vehicle charging piles, which is applied to the application scenario of storing charging cables for new energy vehicle charging piles.

[0025] Current charging cable storage devices for car charging stations only enable the winding and storage of charging cables, without considering the problem of cable twisting during storage. When the cable is stretched and wound in a twisted state, it is easily damaged, thus reducing the cable's lifespan.

[0026] To prevent cable twisting and damage during the winding process, this invention proposes a charging cable storage device for new energy vehicle charging piles. The device is equipped with a torque reduction component, which reduces the torque of the cable, thereby effectively preventing cable damage.

[0027] like Figures 1-6 As shown, the present invention proposes a charging cable storage device for new energy vehicle charging piles, comprising: a charging gun 202, a connecting wire 208, a placement block 1, a torque reduction component 2, and a fixing box 209. The charging gun 202 is placed inside the placement block 1; The torque reduction assembly 2 includes a movable tube 204 and a rotary motor 205; the movable tube 204 is fixedly connected to the connecting line 208, and the rotary motor 205 is connected to the movable tube 204 and can drive the movable tube 204 to rotate. The fixed box 209 is provided with a wire hole and a connecting pipe 14; the fixed box 209 is provided with a wire straightening block 6 and a rotating shaft 12; the rotating shaft 12 is connected to a second rotating motor 11, and the second rotating motor 11 can drive the rotating shaft 12 to rotate. One end of the connecting wire 208 is connected to the charging gun 202, and the other end of the connecting wire 208 passes through the wire hole and the wire straightening block 6, and after being wound on the rotating shaft 12, it comes out of the connecting tube 14.

[0028] This invention proposes a charging cable storage device for new energy vehicle charging piles, which includes a second rotary motor 11 and a rotary shaft 12. The connecting cable 208 is wound around the rotary shaft 12, and the rotary motor 11 drives the rotary shaft 12 to rotate, thereby storing the connecting cable 208 in a fixed box 209. A first rotary motor 205 and a movable tube 204 are provided. The movable tube 204 is fixedly connected to the connecting cable 208. The first rotary motor 205 drives the movable tube 204 to rotate, thereby driving the connecting cable 208 to rotate, which can reduce the twist of the connecting cable 208 and improve its service life.

[0029] In some embodiments, a slot 201 is provided on the placement block 1; the charging gun 202 is inserted into the slot 201 and can be removed from the slot 201.

[0030] The slot 201 is located on the top of the placement block 1. The slot 201 allows the charging gun 202 to be stably inserted into the placement block 1.

[0031] In some embodiments, a limiting tube 203 is provided at the connection between the charging gun 202 and the connecting line 208, and the end of the connecting line 208 is connected to the charging gun 202 within the limiting tube 203.

[0032] The limiting tube 203 is a flared tube with a small opening that restricts the contraction of the connecting wire 208, which breaks due to excessive force.

[0033] In some embodiments, the transmission end of the rotary motor 205 is fixedly connected to the gear 206; the gear 206 meshes with the gear 207; and the gear 207 is connected to the movable tube 204.

[0034] The movable tube 204 is fitted onto the connecting line 208 and fixedly connected to the connecting line 208. The second gear 207 is fixed to the side surface of the movable tube 204. The first rotary motor 205 is fixed onto the movable tube 204. When the first rotary motor 205 is started, it can drive the movable tube 204 to rotate through the first gear 206 and the second gear 207. The rotation of the movable tube 204 drives the connecting line 208 to rotate synchronously.

[0035] The present invention provides a charging cable storage device for new energy vehicle charging piles, and also includes a control system; The control system is used to control the rotation of the rotary motor 205 to reduce the torque of the connecting wire when the connecting wire is twisted.

[0036] The control system includes a host 19, a screen 17, and buttons 18; both the screen 17 and buttons 18 are communicatively connected to the host 19, and the host 19 is also communicatively connected to the induction coil 210, the first rotary motor 205, and the second rotary motor 11.

[0037] Use button 18 to select various commands.

[0038] The instructions are displayed on screen 17.

[0039] In some embodiments, the control system is fixed to a bracket.

[0040] The bracket includes an inclined plate 15, a connecting plate 16, a base plate 20, a ramp 21, and a mounting block 22.

[0041] A connecting plate 16 is fixedly connected to the bottom of the inclined plate 15; a host 19 is fixedly connected to the top of the inclined plate 15, and a screen 17 and a button 18 are fixedly connected to one side of the host 19.

[0042] A base plate 20 is fixedly connected to the bottom of the connecting plate 16. A ramp 21 is provided on the top of the base plate 20. A mounting block 22 is fixedly connected to one side of the base plate 20. An mounting opening 23 is provided inside the mounting block 22. The base plate 20 is placed on the ground, and the bracket is fixed to the ground through the mounting opening 23 on the mounting block 22 to ensure the stability of the bracket.

[0043] In some embodiments, the placement block 1 is fixed to the bracket.

[0044] In some embodiments, a wire hole is provided on the upper surface of the fixing box 209; an induction coil 210 is provided at the wire hole; and a reaction plate 211 is provided on the surface of the connecting wire. The induction coil 210 is used to detect the position of the reaction plate 211 and, based on the position of the reaction plate 211, determine whether the connecting wire is twisted and the direction of the twist. The control system is used to determine the rotation direction of the drive motor 205 according to the twisting direction of the connecting wire when the connecting wire is twisted; according to the rotation direction of the drive motor 205, the drive motor 205 is started to realize timely automatic torque reduction of the connecting wire 208 and prevent the connecting wire 208 from being damaged due to twisting.

[0045] To determine whether the connecting wire is twisted and the direction of the twist, this invention sets induction coils 210 at the upper and lower ends of the wire hole in the fixed box 209. The induction coils are arranged in a circle inside the wire hole, and two reaction plates 211 are set on the outer surface of the connecting wire. The two induction coils 210 detect the two pairs of reaction plates on the side surface of the connecting wire in real time. Based on the position of the reaction plates detected by the two induction coils, it is determined whether the connecting wire is twisted and the direction of the twist can be determined. The induction coils send the detected signal of the twist and the direction of the twist to the host. The host issues a control command according to the direction of the twist, controls the rotation motor to start, and controls the rotation direction of the rotation motor to be opposite to the direction of the twist of the connecting wire. After the rotation motor starts, it drives the gear to rotate. Through the meshing transmission of gear one and gear two, it drives the movable tube and the connecting wire fixed inside it to rotate synchronously, gradually eliminating the twist of the connecting wire until the induction coil detects that the connecting wire is not twisted, and the host controls the rotation motor to stop working. Since the present invention detects the twisting of the connecting wire, it starts the first rotary motor to reduce the torque of the connecting wire. The host determines the direction of the cable twisting based on the position change of the reaction plate detected by the induction coil, and then controls the first rotary motor to rotate forward or backward to ensure precise torque reduction. The induction coil of this invention continuously monitors the twisting state of the connecting wire. Once the twisting of the connecting wire is detected, it immediately triggers the torque reduction to avoid the accumulation of twisting. The horn-shaped limiting tube contracts to limit the excessive force on the connecting wire and the charging gun terminal, reducing the aggravation of twisting caused by uneven force at the end. Furthermore, through the reciprocating left and right movement of the wire straightening block, the connecting wire is orderly wound on the rotating shaft during storage, reducing the probability of new twisting or aggravation of existing twisting during storage.

[0046] In some embodiments, two rollers 7 are provided inside the cable winding block 6; the connecting line 208 passes through the middle of the two rollers 7.

[0047] The roller 7 is rotatably arranged inside the cable straightening block 6. The two rollers 7 are arranged opposite each other, and a channel is provided between the two rollers 7 for the connecting line 208 to pass through. The connecting line 208 passes through the channel, and the two rollers 7 provide guidance for the connecting line 208.

[0048] In some embodiments, a reciprocating lead screw 10 is provided inside the fixed box 209; The winding block 6 is connected to the reciprocating lead screw 10, and the reciprocating lead screw 10 is connected to the lead screw motor; The lead screw motor can drive the reciprocating lead screw 10 to rotate, thereby causing the winding block 6 to move along the reciprocating lead screw 10.

[0049] The bottom of the wire-strapping block 6 is fixedly connected to a fixing rod 8, and the bottom end of the fixing rod 8 is movably connected to a slider 9. The slider 9 is adapted to the reciprocating lead screw 10. The lead screw motor drives the reciprocating lead screw 10 to rotate, which can drive the slider 9 to move along the axial direction of the reciprocating lead screw 10, thereby orderly storing the connecting wire 208 into the fixed box 209.

[0050] Specifically: The lead screw motor drives the reciprocating lead screw 10 to rotate. When the reciprocating lead screw 10 rotates, the slider 9 can move back and forth. The rotary motor 11 drives the rotary shaft 12 to rotate and perform a twisting operation on the connecting wire. The connecting wire first passes through the gap of the winding block 6 and rotates to connect with the side surface of the rotary shaft 12 (the connecting wire is wound around the rotary shaft 12). When the reciprocating lead screw 10 rotates, it causes the slider 9 to move the winding block 6, thereby changing the position of the wire wound on the rotary shaft 12, so that the rotary shaft 12 can collect the wire in sequence when twisting. The lead screw motor and the rotary motor 11 are synchronous and cooperative. They operate simultaneously and complement each other to achieve the orderly collection of the connecting wire. The lead screw motor drives the reciprocating lead screw to rotate, causing the winding block to move laterally left and right, which is responsible for "guiding". The rotary motor 11 drives the rotary shaft to rotate, which is responsible for "winding and collecting". Through the combination of "rotation and twisting + lateral guidance", the connecting wire is prevented from being tangled and messy, and the wire is collected in sequence.

[0051] In some embodiments, a limiting rod 4 is provided inside the fixed box 209; The line-strapping block 6 is slidably connected to the limit rod 4.

[0052] Limiting blocks 3 are fixedly connected to the inner walls of opposite sides of the fixed box 209. Two limiting rods 4 are fixedly connected between the two limiting blocks 3. Movable blocks 5 are movably connected to the side surface of the limiting rods 4. A straightening block 6 is fixedly connected to the bottom of the movable block 5.

[0053] When the winding block 6 moves axially along the reciprocating screw 10, the movement of the winding block 6 is guided by the limiting rod 4.

[0054] In some embodiments, a second rotary motor 11 is fixedly connected to one side of the fixed box 209, a rotary shaft 12 is fixedly connected to the transmission end of the rotary motor 11, and storage trays 13 are fixedly connected to both ends of the rotary shaft 12. A connecting pipe 14 is fixedly connected to one side of the fixed box 209. The connecting wire wound on the rotary shaft 12 is laterally limited by the storage trays 13, so that the connecting wire stored in the fixed box 209 is located between the two storage trays 13.

[0055] This invention proposes a charging cable storage device for new energy vehicle charging piles. The charging gun 202 can be inserted into the placement block 1. The limiting tube 203 has a small, flared opening to prevent the connecting wire 208 from breaking due to excessive force. A rotating motor 205 drives a gear 206 to rotate. Since gear 206 and gear 207 are meshed, and the movable tube 204 is movably connected to the charging gun 202, the rotating motor 205 can drive the movable tube 204 and the connecting wire 208 to rotate. A fixed box 209 stores excess connecting wire 208. When the connecting wire 208 is stored, the two induction coils 210 above and below the wire hole of the fixed box 209 can detect the two pairs of reaction plates 2 on the side surface of the connecting wire 208. 11. Check whether the surface of the connecting wire 208 is twisted, and then send a signal to the host 19 to control the rotary motor 205 to reduce torque, thereby improving the service life of the connecting wire 208. After the connecting wire 208 passes through the winding block 6 and wraps around the rotating shaft 12 once, leaving a large section of connecting wire 208 in the empty position, it passes through the connecting pipe 14 to connect to the power system. The rotary motor 11 drives the rotating shaft 12 to rotate, thereby generating traction force on the connecting wire 208. The reciprocating screw 10 can be rotated by the screw motor. When the reciprocating screw 10 rotates, it drives the slider 9 to move back and forth, thereby driving the winding block 6 to make a reciprocating motion of moving left and right under the limiting action of the limiting rod 4, so that the wire is collected in sequence when the rotating shaft 12 is twisted.

[0056] This invention also proposes a method for storing charging cables in a new energy vehicle charging pile, comprising: Place the charging gun inside the placement block; Start the second rotary motor to drive the rotating shaft to rotate, thereby retracting the connecting wire into the fixed box; When the connecting wire becomes twisted, start the first rotary motor to drive the movable tube to rotate, which in turn drives the connecting wire to rotate, thus reducing the twist of the connecting wire.

[0057] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
