After the charging gun is used, the driving mechanism drives the winding mechanism to wind the charging cable, so that the charging cable is stored in the storage chamber through the wire take-up port, and the charging cable is stored and protected. In this way, it can be ensured that the charging gun and the charging cable are stored in the storage chamber after the charging gun is used. However, during the charging process, the charging cable may still be scattered on the ground, affecting the service life of the charging cable.

[0036] Based on the above analysis, if Figure 1 As shown, the charging cable management device 51 provided in the embodiment of the present application may include:

[0037] Motor 11;

[0038] A winding drum 12, wherein the winding drum 12 is connected to an output shaft of the motor 11;

[0039] a cord 13, one end of which is fixed to the cable drum 12, the other end of which is connected to a charging cable 14, and the cord 13 is wound around a cord receiving portion of the cable drum 12;

[0040] A first controller 15, the first controller 15 is electrically connected to the motor 11, and the first controller 15 is configured to obtain operating parameters of the motor 15, send the operating parameters and receive a control signal or generate the control signal according to the operating parameters, the control signal is used to control the rotation of the motor, so that the motor 11 drives the winding drum 12 to rotate to drive the charging cable 14 connected to the other end of the rope 13 to move, and the operating parameters include one or more of the rotor position of the motor rotor, the rotor speed of the motor rotor and the driving current of the motor.

[0041] In the embodiment of the present application, the motor 11 can drive the rotor to drive the output shaft to rotate by driving current. The winding disk 12 is connected to the output shaft of the motor 11, and when the output shaft of the motor 11 rotates, the winding disk 12 also rotates.

[0042] In the embodiment of the present application, when the motor 11 rotates along the first direction, the cable winding drum 12 rotates along the first direction along with the output shaft of the motor 11, the cable 13 wound around the cable accommodating portion of the cable winding drum 12 gradually increases, and the distance between the charging cable 14 and the cable winding drum 12 gradually decreases, that is, the distance between the charging cable 14 and the ground gradually increases, which can prevent the charging cable 14 from being scattered on the ground and affecting the service life of the charging cable.

[0043] In the embodiment of the present application, when the motor 11 rotates in the second direction, the cable winding drum 12 rotates in the second direction along with the output shaft of the motor 11, the cable 13 wound around the cable accommodating portion of the cable winding drum 12 gradually decreases, and the distance between the charging cable 14 and the cable winding drum 12 gradually increases, that is, the distance between the charging cable 14 and the ground gradually decreases, and the movable distance of the charging cable 14 can be gradually increased, so that the charging gun 53 connected to the charging cable 14 is connected to the electric vehicle to charge the electric vehicle.

[0044] In the embodiment of the present application, the other end of the cord 13 can be connected to the charging cable 14 through a cable clamp. The cable clamp includes: a clamping portion, the clamping portion can detachably clamp the outer periphery of the charging cable 14, and the accommodating space of the clamping portion is adapted to the diameter of the charging cable 14; a connecting portion, the first end of the connecting portion is fixedly connected to one end of the cord 13, and the second end is integrally connected to the clamping portion.

[0045] The cord 13 may be a PE cord, a nylon cord or a steel cord, preferably a PE cord, but the present invention is not limited thereto. The cord 13 may also be a wear-resistant cord made of other materials, such as a Kevlar cord.

[0046] In some embodiments of the present application, Figure 1 As shown, the charging cable management device 51 further includes: an encoder 16, one end of the encoder 16 is connected to the first controller 15, and the other end of the encoder 16 is connected to the rotor of the motor 11, and the encoder 16 is used to generate the rotor position and the rotor speed. That is, the encoder 16 can be used to generate the rotor position and the rotor speed of the motor rotor in the operating parameters.

[0047] In the embodiment of the present application, the encoder 16 can realize the closed-loop feedback control of the motor 11 by the first controller 15. The encoder 16 can control the angular displacement by converting the rotational displacement into a series of digital pulse signals, and can also be used to measure the linear displacement. By controlling the motor 11 through the encoder 16, the accuracy and reliability of the motor 11 can be improved.

[0048] In an embodiment of the present application, when the motor 11 approaches or reaches the target position, the encoder 16 can also verify whether the motor 11 can accurately rotate to the target position. The encoder 16 can detect whether the motor 11 is blocked or stalled during movement, and feed back the detection result to the first controller 15, so that the first controller 15 can adjust the control signal according to the operating parameters of the motor 11. In this way, the encoder 16, the motor 11 and the first controller 15 can form a closed-loop control system. The actual position of the motor 11 can be compared with the target position through the reading of the encoder 16, and the first controller 15 can perform instant correction to achieve high-precision position control.

[0049] In some embodiments of the present application, the charging cable management device 51 further includes:

[0050] A brake mechanism, wherein the brake mechanism is electrically connected to the first controller 15, and the brake mechanism is also connected to a rotating component, wherein the rotating component is one of the rotor of the motor 11, the output shaft of the motor 11 and the winding drum 12, and the brake mechanism 23 is used to prevent the rotating component from rotating; a reducer, wherein one end of the reducer is fixedly connected to the winding drum 12, and the other end of the reducer is connected to the other end of the output shaft of the motor 11.

[0051] In the embodiment of the present application, the reducer 22 can reduce the speed of the motor 11, so that the speed of storing or releasing the wire rope 13 is appropriate, and the output torque is increased. Exemplarily, the reducer 22 can reduce the speed of the motor 11 by 5% to 20%.

[0052] In an embodiment of the present application, the brake mechanism 23 can receive a first state transition signal and a second state transition signal sent by the first controller 15, and the brake mechanism 23 is converted from a locked state to a released state according to the first state transition signal, or from a released state to a locked state according to the second state transition signal.

[0053] When the rope 13 is in a releasing state or a reeling state, the first controller 15 generates and sends a first state transition signal, the brake mechanism 23 receives the first state transition signal, and switches from a locking state to a releasing state according to the first state signal. At this time, the output shaft of the motor 11 rotates, which can drive the winding drum 12 to rotate, so that the rope 13 in the rope accommodating part of the winding drum 12 gradually increases or decreases.

[0054] When the wire rope 13 is in a state of stopping paying out the wire or stopping taking up the wire, the first controller 15 generates and sends a second state transition signal, the brake mechanism 23 receives the second state transition signal, and switches from a released state to a locked state according to the second state signal. At this time, even if the motor 11 is in a power-off state, the output shaft of the motor 11 will not rotate due to the gravity of the wire rope 13 and the charging cable 14, that is, the charging cable can be prevented from falling to the ground, thereby increasing the service life of the charging cable 14.

[0055] In the embodiment of the present application, the first controller 15 can obtain the control signal in two ways, one is to obtain the operating parameters of the motor 11, send the operating parameters and receive the control signal (send the operating parameters to the charging pile, and the second controller inside the charging pile generates control information according to the operating parameters); the second is to generate a control signal according to the operating parameters. The control signal includes the direction and magnitude of the driving current. When the driving current is a positive current, the control signal can be used to control the motor 11 to drive the wire rope accommodating part to release the wire, and when the driving current is a negative current, the control signal can be used to control the motor 11 to drive the wire rope accommodating part to reel in the wire. The magnitude of the driving current can be used to control the release speed or the reeling speed.

[0056] In the first embodiment, if Figure 2 As shown, the first controller 15 is configured to send the operating parameters and receive control signals, including:

[0057] Step S201: sending the operating parameters to the second controller via a preset communication protocol.

[0058] Step S202: receiving the control signal sent by the second controller, and forwarding the control signal to the motor, so that the motor rotates according to the control signal.

[0059] Wherein, the second controller is arranged on the charging pile; the control signal is generated by the second controller according to the operating parameters, and the control signal includes a first line-releasing sub-signal, a first line-stopping sub-signal, a first line-retracting sub-signal and a first line-stopping sub-signal.

[0060] It can be understood that the first wire-releasing sub-signal is used to control the motor 11 to rotate in the second direction, and the motor 11 drives the wire reel 12 to rotate to increase the wire 13 wound around the wire accommodating portion of the wire reel 12, so that the distance between the charging cable 14 and the wire reel 12 gradually decreases. The first wire-releasing stop sub-signal is used to control the motor 11 to stop rotating, that is, to stop reducing the distance between the charging cable 14 and the wire reel 12. The first wire-receiving sub-signal is used to control the motor 11 to rotate in the first direction, and the motor 11 drives the wire reel 12 to rotate to reduce the wire 13 wound around the wire accommodating portion of the wire reel 12, so that the distance between the charging cable 14 and the wire reel 12 gradually increases. The first wire-receiving stop sub-signal is used to control the motor 11 to stop rotating, that is, to stop increasing the distance between the charging cable 14 and the wire reel 12.

[0061] In the embodiment of the present application, the charging cable management device 51 can be controlled by the second controller arranged on the charging pile. The first controller 15 and the second controller perform data transmission according to a preset communication protocol. The second controller receives the operating parameters, generates and sends the control signal according to the operating parameters.

[0062] In this way, the charging cable management device 51 can, under the control of the charging pile, prevent the charging cable from being scattered on the ground after the charging gun 53 is used and during the charging process, thereby increasing the service life of the charging cable 14.

[0063] In the second embodiment, if Figure 3 As shown, the first controller 15 is configured to generate a control signal according to the operating parameters, including:

[0064] Step S301, determining the real-time torque of the motor according to the driving current.

[0065] Step S302: generating the control signal according to the real-time torque, the rotor position and the rotor speed.

[0066] In the embodiment of the present application, the first controller 15 can first obtain the driving current in the operating parameters, and then generate the real-time torque based on the driving current. The real-time torque can be used to determine the stress of the wire rope 13, so that it can be determined whether the motor 11 should release the wire, stop releasing the wire, reel in the wire, or stop reeling in the wire. Combined with the current rotor position and the rotor speed, the rotor speed and rotation time of the motor 11 in the next time period are calculated to generate the control signal.

[0067] In this way, the charging cable management device can automatically control the rotor position, rotor speed and driving current of the motor 11, and can prevent the charging cable from falling to the ground after using the charging gun 53 and during the charging process, thereby increasing the service life of the charging cable 14.

[0068] In some embodiments of the present application, the control signal includes a second pay-off sub-signal, a second stop pay-off sub-signal, a second take-up sub-signal, and a second stop take-up sub-signal; Figure 4 On the basis of, the first controller 15 is configured to generate the control signal according to the real-time torque, including:

[0069] Step S3021: Determine the real-time position of the charging cable according to the rotor position and the rotor speed.

[0070] Step S3022: When the first preset condition is met, the second release sub-signal is generated according to the real-time position and the real-time torque of the rotor.

[0071] Step S3023: When the second preset condition is met, generate the second stop playing sub-signal.

[0072] Step S3024: When the third preset condition is met, a second wire-receiving sub-signal is generated according to the real-time position of the rotor and the real-time torque.

[0073] Step S3025: When the fourth preset condition is met, the second stop line-reeling signal is generated.

[0074] It can be understood that the second pay-out sub-signal is similar to the first pay-out sub-signal, the second stop pay-out sub-signal is similar to the first stop pay-out sub-signal, the second wind-up sub-signal is similar to the first wind-up sub-signal, and the second stop wind-up sub-signal is similar to the first stop wind-up sub-signal, which will not be repeated here.

[0075] In an embodiment of the present application, the first preset condition is any one of the following: a line-releasing indication signal sent by the second controller is received, the limit switch is in an open state, and the first wireless signal transceiver receives a line-releasing operation signal; the second preset condition is any one of the following: a stop-releasing sub-signal sent by the second controller is received, the residence time of the rotor at one of multiple preset stop positions exceeds a first preset time length, and the first wireless signal transceiver receives a stop operation signal; the third preset condition is any one of the following: a line-winding indication signal sent by the second controller is received, the limit switch is in an off state, and the first wireless signal transceiver receives a line-winding operation signal; the fourth preset condition is any one of the following: a stop-winding signal sent by the second controller is received, the real-time position is the initial position of the rotor, the real-time torque is less than or equal to the first preset torque, and the first wireless signal transceiver receives a stop operation signal.

[0076] In which, the limit switch is arranged on the charging gun seat 54 of the charging pile. When the charging gun 53 is disconnected from the charging gun seat 54, the limit switch is in an open state, and when the charging gun 53 is connected to the charging gun seat 54, the limit switch is in an off state; the first wireless signal transceiver is electrically connected to the motor, and the first wireless signal transceiver is used to receive the line-releasing operation signal, the line-reeling operation signal or the stop operation signal.

[0077] In the first example, when the first preset condition is receiving a line-releasing instruction signal sent by the second controller, the second preset condition is receiving a line-releasing sub-signal sent by the second controller to stop the line-releasing, the third preset condition is receiving a line-winding instruction signal sent by the second controller, and the fourth preset condition is receiving a line-winding stop signal sent by the second controller.

[0078] In the second example, when the first preset condition is that the limit switch is in an open state, the second preset condition is that the rotor stays for a period of time exceeding a first preset time length at one of multiple preset stop positions, the third preset condition is that the limit switch is in an off state, and the fourth preset condition is that the real-time position is the initial position of the rotor or the real-time torque is less than or equal to the first preset torque.

[0079] In the third example, when the first preset condition is that the first wireless signal transceiver receives a line-releasing operation signal, the second preset condition is that the first wireless signal transceiver receives a stop operation signal, the third preset condition is that the first wireless signal transceiver receives a line-recovering operation signal, and the fourth preset condition is that the first wireless signal transceiver receives a stop operation signal.

[0080] It can be understood that, based on the first preset condition, the second preset condition, the third preset condition and the fourth preset condition, the first controller 15 can also be configured to generate the second pay-out sub-signal, the second stop pay-out sub-signal, the second wind-up sub-signal and the second stop wind-up sub-signal under other conditions.

[0081] In some embodiments of the present application, the first controller 15 is configured to generate the second discharge sub-signal according to the real-time position and the real-time torque of the rotor, including:

[0082] When the real-time position is one of the plurality of preset stop positions and the real-time torque is greater than or equal to a second preset torque, the second pay-off sub-signal is generated.

[0083] In the embodiment of the present application, the real-time position refers to the real-time position of the rotor. The preset stop position can be any position between the starting position and the ending position of the rotor. The plurality of reserved stop positions can be evenly distributed between the starting position and the ending position, or can be unevenly distributed between the starting position and the ending position.

[0084] It can be understood that when the real-time position is not any of the plurality of preset stop positions, the motor 11 pays out the wire (reduces the wire 13 in the wire accommodating portion) in response to the second pay-out sub-signal. If the rotor stays at one of the plurality of preset stop positions for a time period exceeding the first preset time length, a second stop pay-out sub-signal is generated so that the motor 11 stops paying out the wire (stops reducing the wire 13 in the wire accommodating portion) in response to the second stop pay-out sub-signal.

[0085] In the embodiment of the present application, if the real-time position of the rotor is one of the multiple preset stop positions, and the charging gun 53 has not yet reached the electric vehicle, the user continues to stretch the charging gun 53, thereby stretching the charging cable 14, the cord 13, the winding drum 12, and the motor 11. At this time, the increase in the pulling force of the user continuing to stretch the charging gun 53 is converted into an increase in the real-time torque transmitted to the rotor of the motor 11 through the charging cable 14, the cord 13, the winding drum 12, and the reducer 22, so that the driving current of the motor 11 increases. In other words, the real-time torque acting on the rotor of the motor 11 formed by the pulling force of the user continuing to stretch the charging gun 53 has a positive correlation with the real-time current of the motor.

[0086] Specifically, when the real-time position of the rotor of the motor 11 is one of the preset stop positions, the rotor of the motor 11 stops rotating in the unwinding direction, and the winding drum 12 also stops rotating, so that the wire rope 13 is no longer unwound from the winding drum 12. Figure 4 As shown, when the user continues to pull the charging gun 53 and the pulling force increases, the real-time torque generated by the charging gun 53 and transmitted to the rotor of the motor 11 is obtained. Then, it is determined whether the real-time torque exceeds the stop position pay-off torque. When the real-time torque does not exceed the preset stop position pay-off torque, that is, when the real-time current of the motor 11 does not exceed the preset stop position pay-off current, the rotor of the motor 11 remains stationary, the winding drum 12 also remains stationary, the charging cable management device 51 no longer pays off the wire, and the length of the wire rope 13 paid out of the charging cable management device 51 remains fixed. When the real-time torque exceeds the preset stop position pay-off torque, that is, when the real-time current of the motor exceeds the preset stop position pay-off current, the rotor of the motor 11 starts to rotate, driving the winding drum 12 to rotate, and the charging cable management device 51 continues to pay off the wire, and the wire rope 13 is paid out of the length preset by the charging cable management device 51 to the next stop position.

[0087] In this way, the real-time position and the real-time torque are used to jointly confirm whether to release the cable, and the second release sub-signal is a multi-segment release method, so that the release length of the charging cable is adapted to the length between the charging pile and the electric vehicle. This ensures that after the charging gun 53 is used and during the charging process, the charging cable will not fall to the ground, thereby increasing the service life of the charging cable 14.

[0088] In some embodiments of the present application, when the real-time torque is greater than or equal to the second preset torque, and the real-time torque is less than the third preset torque, the second pay-off sub-signal is used to instruct the motor to pay out the wire at the first pay-off speed; when the real-time torque is greater than the third preset torque, the second pay-off sub-signal is used to instruct the motor to pay out the wire at the second pay-off speed.

[0089] In the embodiment of the present application, according to the comparison result of the real-time torque with the second preset torque and the bottom order preset torque, it is determined whether the motor 11 indicated by the second pay-off sub-signal pays off the wire at the first pay-off speed or the second pay-off speed. The third preset torque is greater than the second preset torque, and the second pay-off speed is greater than the first pay-off speed.

[0090] It should be noted that, similarly, multiple preset torques can be set to generate multiple pay-off speeds accordingly.

[0091] In this way, the pay-off speed can be adjusted according to the torque used to stretch the charging cable to improve the user experience.

[0092] In some embodiments of the present application, the first controller 15 is further configured to:

[0093] When the first line-releasing sub-signal is received, the first line-retracting sub-signal is received, the second line-releasing sub-signal is received, the second line-retracting sub-signal is received, the first preset condition is satisfied, or the third preset condition is satisfied, a first state transition signal is generated, and the first state transition signal is sent to the brake mechanism 23, wherein the first state transition signal is used to instruct the brake mechanism 23 to switch from a locked state to a released state;

[0094] When the first stop paying out the line sub-signal is received, the first stop winding up the line sub-signal is received, the second stop paying out the line sub-signal is received, the second stop winding up the line sub-signal is received, the second preset condition is satisfied, or the fourth preset condition is satisfied, a second state transition signal is generated and the second state transition signal is sent to the brake mechanism 23, and the second state transition signal is used to instruct the brake mechanism 23 to switch from a released state to a locked state.

[0095] When the rope 13 is in a pay-out state or a take-up stop state, the first controller 15 generates and sends a first state transition signal, the brake mechanism 23 receives the first state transition signal, and switches from a locked state to a released state according to the first state signal. At this time, the output shaft of the motor 11 rotates, which can drive the winding drum 12 to rotate, so that the rope 13 in the rope accommodating part of the winding drum 12 gradually increases or decreases.

[0096] When the wire rope 13 is in a state of stopping paying out the wire or stopping taking up the wire, the first controller 15 generates and sends a second state transition signal, the brake mechanism 23 receives the second state transition signal, and switches from a released state to a locked state according to the second state signal. At this time, even if the motor 11 is in a power-off state, the output shaft of the motor 11 will not rotate due to the gravity of the wire rope 13 and the charging cable 14, that is, the charging cable can be prevented from falling to the ground, thereby increasing the service life of the charging cable 14.

[0097] In combination with the above charging cable management device, Figure 4 As shown, a charging pile provided in an embodiment of the present application includes:

[0102] A charging gun holder 54 is detachably connected to the charging gun 53 .

[0103] In the embodiment of the present application, the charging gun holder 54 may be disposed on the body 52 .

[0104] In the embodiment of the present application, the main body 52 can output voltage to power the charging cable management device 51, and at the same time, when connected to the electric vehicle through the charging cable 14 and the charging gun 53, the electric vehicle is charged.

[0105] In some embodiments of the present application, Figure 4 As shown, the charging cable management device 51 is fixedly arranged on the top of the body 52. ​​In this way, the length of the charging cable 14 can be increased to increase the probability that the charging pile can be connected to the electric vehicle through the charging cable 14 and the charging gun 53, thereby increasing the use frequency of the charging pile.

[0106] In some embodiments of the present application, Figure 4 As shown, the charging pile further includes: a waterproof connector 55, one end of which is connected to the charging cable management device 51, and the other end of which is connected to the body 52. ​​In this way, for the charging pile installed outdoors, the waterproof connector 55 can prevent the charging cable management device 51 and the charging pile from being damaged by the infiltration of rain, dew or water vapor, thereby improving the safety of the charging pile.

[0107] In some embodiments of the present application, the main body 52 also includes: a second controller, which is electrically connected to the first controller 15 through the waterproof connector; the second controller is configured to: receive the operating parameters sent by the first controller 15 according to a preset communication protocol; generate the control signal according to the operating parameters, and send the control signal to the first controller 15, the control signal including a first pay-out sub-signal, a first stop pay-out sub-signal, a first retracting sub-signal and a first stop retracting sub-signal, and the first controller 15 is arranged in the charging cable management device.

[0108] In this way, the charging cable management device 51 can, under the control of the charging pile, prevent the charging cable from being scattered on the ground after the charging gun 53 is used and during the charging process, thereby increasing the service life of the charging cable 14.

[0110] In some embodiments of the present application, the control switch is a toggle switch or an induction switch.

When the charging gun 53 and the charging gun holder 54 are not connected, the limit switch is in an open state, and the first controller 15 and the second controller can communicate with each other. The second controller is configured to: when the limit switch is in an open state, send a line-release indication signal, a stop line-release sub-signal, a line-reeling indication signal or a stop line-reeling signal to the first controller 15.

[0113] It can be understood that the limit switch is arranged on the charging gun seat 54. When the charging gun 53 is used, the limit switch is in the open state, so that the first controller 15 and the second controller can communicate instantly, avoiding the failure to send or the delay in sending the line-release instruction signal, the stop line-release sub-signal, the line-reeling instruction signal or the stop line-reeling signal, thereby improving the working efficiency.

[0114] In some embodiments of the present application, the charging gun 53 includes: a second wireless signal transceiver, which matches the first wireless signal transceiver; the second wireless signal transceiver is configured to receive an operation signal input by a user and send the operation signal to the first wireless signal transceiver, and the operation signal is a line-releasing operation signal or a line-reeling operation signal.
