Description

[0002] Charging piles can be fixed on the ground or on the wall, installed in public parking lots, residential community parking lots or charging stations, and charge various models of electric vehicles according to different voltage levels. Generally, a charging gun is provided on the charging pile, and the charging gun is connected to the charging pile through a gun cable. During the charging process of the user using the charging gun or after charging is completed, the gun cable may be scattered on the ground and may even be run over by a vehicle, which may damage the gun cable and affect the service life of the gun cable. Especially when the diameter of the gun cable exceeds 30mm and the length of the gun cable exceeds 5 meters, when the user removes the charging gun from the charging pile and inserts it into the vehicle for charging, the user needs to overcome: the weight of the gun cable itself (generally 5-20 Kg), the frictional resistance between the gun cable and the ground, and the force to rotate the gun cable, which is very laborious to operate.

[0036] The technical solution of the present application will be described in detail below with reference to embodiments and drawings.

Figure 5 is a schematic diagram of the sectional structure of the gun wire management device shown in some embodiments of the present application.

[0038] Referring to Figure 1 shown, some embodiments of the present application provide a gun wire management device 100. The gun wire management device 100 includes: a housing 110; a detachable wire reel cover 120 located at one end of the housing 110. The housing 110 is in a cylindrical shape and is used to accommodate components such as a stator, a rotor, and a rotating shaft (which will be described below). The wire reel cover 120 is used to protect the wire reel located inside the wire reel cover 120.

[0039] Continuing to refer to Figure 1 shown, a collar 111 that circumferentially sleeves and fixes the housing 110 and an installation structure 112 that is connected to the collar 111 and is used to install the housing 110 on a charging pile are provided on the housing 110. The installation structure 112 has installation holes and can be installed on the charging pile through screws.

[0040] Continuing to refer to Figure 1 shown, a wire interface 113 is also provided on the housing 110. A wire 114 passes through the wire interface 113 and is electrically connected to corresponding components (such as a controller and a coil, etc.) inside the housing 110 to supply power to them.

[0041] Referring to Figure 2As shown, after removing the wire spool cover 120, the wire spool 130 located inside the wire spool cover 120 is exposed. The wire spool 130 is used for winding the wire rope. One end of the wire rope is connected and wound around the wire spool 130. Among them, when the wire spool 130 rotates in the first direction, the wire rope is paid out; when the wire spool 130 rotates in the second direction, the wire rope is rewound. The other end of the wire rope can be connected to the gun line through a cable clamp. The wire rope can be a PE rope, a nylon rope or a steel wire rope, preferably a PE rope. It should be noted that the present application is not limited thereto. The wire rope can also adopt wear-resistant wire ropes of other materials, such as Kevlar ropes, etc.

[0042] Reference Figure 3 As shown, after removing the wire spool 130, the rotating shaft 140 connected to the wire spool 130 is exposed. The wire spool 130 can be driven to rotate by the rotating shaft 140. The rotating shaft 140 extends out from inside the housing 110.

[0043] Reference Figure 4 and Figure 5 As shown, a stator 150, a rotor 160 that rotates around the stator 150, and a rotating shaft 140 fixedly connected to the rotor 160 are arranged inside the housing 110. One end of the rotating shaft 140 is fixedly connected to the center of the rotor 160, and the rotating shaft 140 is configured to be driven to rotate by the rotor 160. The other end of the rotating shaft 140 is embedded in the center of the wire spool 130 and fixedly connected to the center of the wire spool 130. The wire spool 130 is configured to be driven to rotate by the rotating shaft 140. Coils are wound around the stator 150. The coils are powered by the electric wire 114. By controlling the current switch and the current magnitude in the coils, the torque and the torque magnitude generated by the rotor 160 and the rotating shaft 140 can be controlled, and further the wire spool 130 can be controlled to pay out or rewind the wire. The technical solution of the present application uses the electric control gun line management device 100 to cooperate with the user to use the charging gun, and controls the coil current to make the rotating shaft 140 generate a torque to balance the gravity of the charging gun, reducing the force required by the user.

[0044] Reference Figure 4 and Figure 5 As shown, the rotor 160 is in the shape of a cover and covers the outer circle of the stator 150. The rotating shaft 140 passes through the center of the rotor 160 and is fixedly connected to the center of the rotor 160 at the passing position.

[0045] Continue to refer to Figure 4 and Figure 5As shown, a first bearing 141 and a second bearing 142 are sleeved on the rotating shaft 140. The first bearing 141 and the second bearing 142 assist the rotation of the rotating shaft 140 to make its rotation smoother. The inner side of the lower end 141a of the first bearing 141 is supported by the rotating shaft 140, the outer side of the lower end 141a of the first bearing 141 is supported by the housing 110, and the inner side of the upper end 141b of the first bearing 141 supports the rotor 160. The outer side of the lower end 142a of the second bearing 142 is supported by a braking mechanism, the outer side of the upper end 142b of the second bearing 142 is limited by the housing 110, and the inner side of the upper end 142b of the second bearing 142 supports the rotating shaft 140. Specifically, a support portion 115 with a substantially L-shaped cross section extends from the inner side of the housing 110. Both ends of the support portion 115 respectively form limiting portions for limiting the outer rings of the first bearing 141 and the second bearing 142, and partially fixedly support the outer rings of the first bearing 141 and the second bearing 142. A stator accommodation cavity is formed between the support portion 115 and the outer shell 110 to accommodate the stator 150.

[0046] Continue to refer to Figure 4 and Figure 5 As shown, a limiting structure 116 is also provided on the top surface of the support portion 115 by screws for axially limiting the first bearing 141 and the rotor 150.

[0047] Continue to refer to Figure 4 and Figure 5 As shown, the wire management device 100 of the gun further includes: a braking mechanism 143. The braking mechanism 143 is connected to the rotating shaft 140 and is used to prevent the rotating shaft 140 from rotating. Specifically, the braking mechanism 143 includes a main body portion 143a, a movable portion 143b, and a limiting portion 143c. A coil and an elastic member connected to the movable portion are provided on the main body portion 143b. The movable portion fixes the limiting portion under the elastic force of the elastic member, and the limiting portion is fixedly connected to the rotating shaft and moves synchronously with the rotating shaft. The movable portion is, for example, a flat plate structure and has magnetism. The cross section of the limiting portion is L-shaped. The movable portion abuts against the bottom edge of the L, and the side edge of the L is matched with the second thread structure on the side wall of the rotating shaft through the first thread structure. When the coil on the main body portion is not powered on, the movable portion abuts against and fixes the limiting portion under the elastic force of the elastic member, thereby fixing the rotating shaft to prevent the rotating shaft from rotating. When the coil on the main body portion is powered on, the magnetic field generated by the coil attracts the movable portion, thereby releasing the limiting portion and releasing the rotating shaft so that the rotating shaft can rotate.

[0048] Continue to refer to Figure 4 and Figure 5As shown, the gun line management device 100 further includes: a controller 170, the controller 170 is electrically connected to the coils on the stator 150 and the coils on the brake mechanism 143 respectively, and the controller is configured to control the coil current on the stator and the coil current on the brake mechanism respectively. The controller 170 is, for example, a circuit board. The controller 170 is powered by a wire 114. At least one output torque displacement corresponding curve formed by a plurality of preset shaft output torques respectively corresponding to a plurality of preset displacement amounts is preset in the controller (for example, Figure 6 the shaft torque control curve shown, Figure 8 the wire winding curve and the wire unwinding curve shown) so that the pulling force generated by the shaft output torque acting on the gun line through the wire rope matches the nominal gravity of the gun line.

[0049] Continuing to refer to Figure 4 and Figure 5 shown, in some embodiments of the present application, the gun line management device 100 further includes: an encoder 180, one end of the encoder 180 is connected to the controller 170, the other end of the encoder 180 is connected to the shaft 140, and the encoder 180 is used to generate the rotational displacement of the shaft 140. The controller 170 defines the initial position of the wire rope gun line connection end and the displacement amount of the wire rope gun line connection end relative to the initial position according to the shaft rotational displacement generated by the encoder 180.

[0050] Continuing to refer to Figure 4 and Figure 5 shown, in some embodiments of the present application, the gun line management device 100 further includes: a housing for accommodating the stator, rotor and shaft, the top of the housing 110 has a top cover 121 and a first sealing ring 122 located between the housing and the top cover, the bottom of the housing 110 has a bottom cover 123 and a second sealing ring 124 located between the housing and the bottom cover, and the bottom of the housing has a recess and a cover 125 for closing the recess and a third sealing ring 126 located between the housing and the cover.

[0051] In some embodiments of the present application, the nominal gravity of the gun line refers to the pulling force acting on the gun line connection end of the wire rope when the operator only holds the charging gun almost still, which is the displacement amount of the gun line connection end of the wire rope at different wire ropes relative to the initial position. Without external force, the output torque of the rotating shaft generated by the coil current on the stator always drives the wire winding disc to wind up the wire rope, that is, drives the wire winding disc to rotate in the wire collecting direction so that the gun line connection end of the wire rope moves towards the initial position, thereby generating a lifting force on the gun line. That is to say, without external force, the coil current on the stator always makes the rotor tend to rotate in the wire collecting direction to generate the output torque of the rotating shaft. Matching means that the lifting force acting on the gun line through the wire rope generated by the output torque of the rotating shaft is very close to the nominal gravity of the gun line and is equivalent to the total static friction force generated by each component. For example, the difference between the lifting force acting on the gun line through the wire rope generated by the output torque of the rotating shaft and the nominal gravity of the gun line is less than or equal to 20N. Preferably, the difference between the lifting force acting on the gun line through the wire rope generated by the output torque of the rotating shaft and the nominal gravity of the gun line is less than or equal to 15N. More preferably, the difference between the lifting force acting on the gun line through the wire rope generated by the output torque of the rotating shaft and the nominal gravity of the gun line is less than or equal to 10N. More preferably, the difference between the lifting force acting on the gun line through the wire rope generated by the output torque of the rotating shaft and the nominal gravity of the gun line is less than or equal to 10N. Ideally, the difference between the lifting force acting on the gun line through the wire rope generated by the output torque of the rotating shaft and the nominal gravity of the gun line is less than or equal to 5N, and particularly ideally less than or equal to 3N. The smaller the difference between the two, the smaller the force required for the operator to pull the charging gun away from the charging pile, and the better the feel when pulling out the wire.

[0052] In some embodiments of the present application, the number of the plurality of displacement amounts is preset in the controller. To obtain a better feel, the more the number of the plurality of displacement amounts, the better, for example, more than 5. However, too many numbers of the plurality of displacement amounts increase too much workload during factory settings, and the degree of improvement in feel does not increase significantly at the same time. Therefore, for general charging piles, the number of the plurality of displacement amounts does not exceed 30. Preferably, the number of the plurality of displacement amounts is greater than or equal to 10 and less than or equal to 20. Ideally, the number of the plurality of displacement amounts is greater than or equal to 12 and less than or equal to 18, such as 16.

[0053] In some embodiments of the present application, the output torque displacement corresponding curve between two adjacent displacement amounts among the preset plurality of displacement amounts is formed by interpolation method. That is to say, Figure 6The shown shaft torque control curve is formed by interpolation. The interpolation method includes, but is not limited to, linear interpolation. The output torque between adjacent displacement amounts can also be any constant value of the shaft output torques corresponding to two set points, and preferably the value of the shaft output torque corresponding to the displacement amount close to the initial position.

[0054] In some embodiments of the present application, the initial position of the wire rope gun wire connection end is determined by an offset preset relative to the wire rope zero position. The wire rope zero position is the position of the wire rope connection end corresponding to the rotational displacement of the shaft generated by the encoder read by the controller when the wire rope is recovered through a preset wire rope recovery program and the wire rope at the gun wire connection end is restricted so that the coil current on the stator is not lower than a preset zero position positioning current. The preset offset can be 0 or any value that meets the requirements of gun wire management.

[0055] In some embodiments of the present application, the at least one output torque displacement corresponding curve includes a wire winding curve ( Figure 8 the shown wire winding curve). The pulling force acting on the gun wire through the wire rope generated by the shaft output torque preset for any preset displacement amount in the wire winding curve is greater than the nominal gravity of the gun wire corresponding to this preset displacement amount (gun wire gravity curve). The wire winding curve does not specifically refer to the curve in the wire winding state, but rather the pulling force acting on the gun wire through the wire rope generated by the shaft output torque preset for any preset displacement amount in this curve is greater than the nominal gravity of the gun wire corresponding to this preset displacement amount. In this way, the pulling force exerted by the charging pile gun wire management device on the gun wire is greater than the nominal gravity of the gun wire at any point of the displacement amount of the wire rope gun wire connection end relative to the initial position, so that the wire rope gun wire connection end connecting the gun wire has a tendency to move towards the initial position until, considering friction, the resultant force of the operator's pulling force and the nominal gravity of the gun wire is balanced with the pulling force acting on the gun wire through the wire rope generated by the wire winding curve, and the gun wire hovers at the position corresponding to this displacement amount.

[0056] When the gun line hovers, if the pulling force of the operator on the gun line increases, the resultant force of the pulling force and the nominal gravity of the gun line is greater than the lifting force acting on the gun line through the wire rope generated by the wire receiving curve at this position. That is to say, the rotor of the motor cannot be maintained by the output torque generated by the preset stator current corresponding to the displacement of the wire rope connection end of the gun line, which makes the rotor rotate in the wire receiving direction. The wire reel rotates in the wire releasing direction under the combined action of the pulling force of the operator and the nominal gravity of the gun line, releasing the wire rope. Generally, the resultant force of the pulling force of the operator and the nominal gravity of the gun line will decrease as the displacement of the wire rope connection end of the gun line increases. At the same time, the lifting force acting on the gun line by the wire rope decreases according to the wire receiving curve until a certain displacement position is reached. When the resultant force of the pulling force of the operator and the nominal gravity of the gun line is balanced with the lifting force acting on the gun line through the wire rope generated by the wire receiving curve at this position, the gun line hovers at this position. If the pulling force of the operator on the gun line decreases, the resultant force of the pulling force of the operator and the nominal gravity of the gun line decreases. At the same time, the lifting force acting on the gun line by the wire rope decreases according to the wire receiving curve. When the resultant force of the pulling force of the operator and the nominal gravity of the gun line is balanced with the lifting force acting on the gun line through the wire rope generated by the wire receiving curve at this position, the gun line hovers at this position.

[0057] In some embodiments of the present application, when the wire rope lifts the gun line to the initial position, the gun line hovers at the initial position under the action of the wire rope lifting force greater than the nominal gravity of the gun line to enter the standby state. The working modes of the controller of the present application include: pure torque mode. In the pure torque mode, there is no signal communication between the motor and the charging pile, and the motor only operates according to the calibrated points in the torque mode ( Figure 6The shown shaft torque control curve). The torque of the motor at each point (pulling out a certain length of the cable) should be greater than the actual weight of the cable at that position, so as to ensure that after pulling out to a certain point to complete charging, the output torque of the motor minus the weight of the cable at that point can overcome the friction force and retract the cable. In the pure torque mode, the user needs to apply a certain force to pull out the gun line. The working process of the pure torque mode is as follows: The charging gun is inserted into the charging gun seat, and the wire rope lifts the gun line to the initial position. The gun line hovers at this initial position under the action of the wire rope pulling force greater than the nominal gravity of the gun line and enters the standby state; in the standby state, if the operator pulls the gun line, when the resultant force of the pulling force of the operator pulling the gun line and the nominal gravity of the gun line is greater than the pulling force acting on the gun line through the wire rope generated by the wire take-up curve at this position, that is, the rotor of the motor cannot be maintained by the output torque generated by the preset stator current corresponding to the displacement of the wire rope gun line connection end that makes the rotor rotate in the wire take-up direction, the wire reel rotates in the wire release direction under the action of the resultant force of the operator's pulling force and the nominal gravity of the gun line, and the charging pile gun line management device starts to release the wire. Generally, the resultant force of the operator's pulling force and the nominal gravity of the gun line will decrease as the displacement of the wire rope gun line connection end increases, and at the same time, the pulling force acting on the gun line by the wire rope decreases according to the wire take-up curve until reaching a certain displacement position, where the resultant force of the operator's pulling force and the nominal gravity of the gun line is balanced with the pulling force acting on the gun line through the wire rope generated by the wire take-up curve at this position, and the gun line hovers at this position. If the pulling force of the operator pulling the gun line decreases, the resultant force of the operator's pulling force and the nominal gravity of the gun line decreases, and at the same time, the pulling force acting on the gun line by the wire rope decreases according to the wire take-up curve, and the resultant force of the operator's pulling force and the nominal gravity of the gun line is balanced with the pulling force acting on the gun line through the wire rope generated by the wire take-up curve at this position, and the gun line hovers at this position.

[0058] In the pure torque control mode, no additional signals need to be set, and the controller 170 controls the rotating shaft according to the sensed change in the acting force on the rotating shaft and the rotational displacement of the rotating shaft. In the pure torque control method, the gun line management device and the wire rope work like a rubber band. The torque control curve of the rotating shaft is slightly larger than the nominal gravity curve of the gun line. When the user holds the charging gun by hand, as long as a force needs to be applied and this force is greater than the torque difference, the rotating shaft can sense it and perform corresponding movements. During wire release: When the user holds the charging gun by hand and drives the gun line to pull the rotating shaft, the controller senses through the coil current that the force acting on the rotating shaft is greater than the torque difference, and enters the wire release state from the standby state. During wire retraction: After the user finishes charging and pulls out the charging gun from the vehicle and walks towards the charging pile, the controller senses that the load becomes smaller, and the difference between the actual load at the corresponding position and the torque control curve of the rotating shaft is greater than the torque difference, and enters the wire retraction state from the charging state. During the user's use of the charging gun, the controller can sense the rotational displacement of the rotating shaft (i.e., the position of the charging gun), and controls the actual torque of the rotating shaft according to the rotational displacement of the rotating shaft based on Figure 6 the schematic diagram of the preset torque of the rotating shaft shown.

[0059] In addition, in the torque control method, the rotation speed of the rotating shaft and the speeds of wire release and wire retraction can also be controlled. The corresponding speed curves can be set according to the torque control curve of the rotating shaft. Throughout the entire stroke, the torque control curve and the speed curve of the rotating shaft can be divided into 16 segments (at least 5 segments), the spacing of each segment can be freely set, and the torque value of each segment needs to be calibrated according to the load weight situation. During wire release, the set torque is basically balanced with the nominal gravity of the gun line, so that the user can slightly apply a downward pulling force to break the balance and let the gun line go down; during wire retraction, according to the set parameter situation, generally the torque control curve of the rotating shaft will be slightly larger than that during wire release. At this time, as long as there is no external force pulling the gun line, when the torque of the rotating shaft is greater than the nominal gravity of the gun line, the wire will be retracted, and the retraction speed will also change in real time according to the set speed curve. Generally, the closer to the charging pile, the slower the wire retraction speed needs to be.

[0060] In some embodiments of the present application, after the charging gun is inserted into the vehicle charging port, the gun line hovers at a position where the resultant force of the resistance that prevents the charging gun from being pulled out of the vehicle charging port and the nominal gravity of the gun line acting on the charging gun is balanced with the pulling force acting on the gun line through the wire rope according to the wire retraction curve, and the resistance includes the friction between the charging gun and the vehicle charging port and / or the resistance generated by anti-disengagement.

[0061] In some embodiments of the present application, when the pulling force acting on the gun line through the wire rope according to the wire retraction curve is greater than the resultant force of the operator's pulling force and the nominal gravity of the gun line, the controller controls the rotor to drive the wire reel to rotate in the wire retraction direction with a preset wire retraction speed displacement curve to reduce the displacement amount of the wire rope gun line connection end.

[0062] In some embodiments of the present application, the number of the preset multiple displacement amounts and the number of the preset multiple shaft output torques are greater than or equal to 5 and less than or equal to 30. In some embodiments of the present application, the number of the preset multiple displacement amounts and the number of the preset multiple shaft output torques are greater than or equal to 10 and less than or equal to 20. In some embodiments of the present application, the number of the preset multiple displacement amounts and the number of the preset multiple shaft output torques are greater than or equal to 12 and less than or equal to 18.

[0063] In some embodiments of the present application, the lifting force acting on the gun line through the wire rope generated by the shaft output torque differs from the nominal gravity of the gun line by less than or equal to 15N. In some embodiments of the present application, the lifting force acting on the gun line through the wire rope generated by the shaft output torque differs from the nominal gravity of the gun line by less than or equal to 10N. In some embodiments of the present application, the lifting force acting on the gun line through the wire rope generated by the shaft output torque differs from the nominal gravity of the gun line by less than or equal to 5N. In some embodiments of the present application, the lifting force acting on the gun line through the wire rope generated by the shaft output torque differs from the nominal gravity of the gun line by less than or equal to 3N.

[0064] In some embodiments of the present application, after the controller 170 receives a brake signal, the controller controls the brake mechanism to brake and prevent the shaft from rotating, and reduces or disconnects the coil current of the stator. When the controller receives a brake release signal, the controller controls the brake mechanism to release the brake so that the shaft can rotate. The brake signal and the brake release signal can be switch signals or communication signals. For example, a switch signal generated by an induction device provided on the charging pile. Further, the induction device is installed on the charging gun or the charging gun seat of the charging pile, and the signal generated when it senses that the charging gun is pulled out of the charging gun seat is the brake release signal, and the signal generated when it senses that the charging gun is inserted into the charging gun seat is the brake signal. The brake signal and the brake release signal can also be communication signals generated by the main board of the charging pile or other devices according to a preset communication protocol.

[0065] In some embodiments of the present application, the working mode of the controller includes: a torque mode with a brake signal. Refer to Figure 10As shown, the working process is as follows: Initially, it is in the standby state. At this time, the motor is turned off, and the brake holds the motor tightly to suspend the gun line at the initial position. After the user pulls out the charging gun, after the controller 170 receives the brake release signal, it controls the coil on the brake mechanism 143 to be energized to release the brake mechanism 143, and controls the coil on the stator to be energized to start the motor. Then the device works in the pure torque mode described above, including wire release and wire retraction. Until the charging is completed and after wire retraction, the charging gun is inserted into the charging gun seat. After the controller 170 receives the brake signal, it controls the brake mechanism 143 to hold tightly, controls the coil on the stator to be de-energized to turn off the motor, and returns to the standby state.

[0066] In some embodiments of the present application, referring to Figure 9 As shown, the device further includes: The at least one output torque-displacement corresponding curve further includes a wire release curve. The pulling force generated by the output torque of the rotating shaft preset for any preset displacement amount in the wire release curve acting on the gun line through the wire rope is less than the nominal gravity of the gun line corresponding to this preset displacement amount.

[0067] In some embodiments of the present application, the device further includes: When the controller receives the brake release signal, the controller also controls the pulling force generated by the output torque of the rotating shaft acting on the gun line through the wire rope according to the wire release curve. The pulling force generated by the output torque of the rotating shaft preset for any preset displacement amount in the wire release curve acting on the gun line through the wire rope is smaller than the nominal gravity of the gun line corresponding to this preset displacement amount, so that the pulling force required by the operator considering the friction effect is smaller than that of the wire retraction curve, and the operator's feeling of pulling out the gun line is better. Even when the operator needs to pull out the gun line, controlling it according to the wire release curve can achieve pulling out the gun line without an additional pulling force greater than the force constituting the nominal gravity of the gun line.

[0068] In some embodiments of the present application, the device further includes: When the controller receives the gun removal signal that the charging gun is pulled out from the vehicle charging port, the controller controls the pulling force generated by the output torque of the rotating shaft acting on the gun line according to the wire retraction curve.

[0069] In some embodiments of the present application, the device further includes: When the controller receives the gun removal signal generated by the charging gun being pulled out from the vehicle charging port, the controller also controls the brake mechanism to release the brake so that the rotating shaft can rotate.

[0070] In some embodiments of the present application, the device further includes: after the controller receives a signal to be charged generated by the charging gun being inserted into the charging port of the vehicle, the controller controls the brake mechanism to brake to prevent the shaft from rotating, and reduces or disconnects the current of the stator. The gun removal signal and the signal to be charged can be obtained through the signal line of the charging gun itself, without the need for additional sensors. The gun removal signal and the signal to be charged can also be sent to the controller through a specific communication protocol after the motherboard or other device receives the above-mentioned signal of the charging gun.

[0071] In some embodiments of the present application, the working mode of the controller includes: variable torque mode. In this control mode, the controller 170 also receives a feedback signal and controls the coil current on the stator according to the feedback signal, and the feedback signal includes a take-up signal, a pay-out signal, a standby signal and a charging signal. As the name implies, the take-up signal means that the user needs to return the charging gun and retract the gun line after using it; the pay-out signal means that the user needs to let the gun line out to the position of the electric car when using the charging gun for charging; the standby signal means when the charging gun is not in use and is placed on the charging pile; the charging signal means when the user is using the charging gun to charge the electric car. Reference Figure 10 As shown, the working process is as follows: the initial state is the standby state, at which the motor is turned off, and the brake holds the motor so that the gun line is suspended at the initial position; after the user pulls out the charging gun from the charging gun seat, the controller 170 receives the brake release signal and controls the coil on the brake mechanism 143 to energize so that the brake mechanism 143 is released, and controls the coil on the stator to energize so that the motor starts; then enters the line release state, and the device Figure 9 After the charging gun is inserted into the charging port of the electric vehicle, it enters the charging state. At this time, the gun line is controlled to hover, which can be achieved by braking or by enabling the motor. After charging is completed, the user pulls the gun out of the charging port and enters the line collection state. Figure 9 After winding the wire, the charging gun is inserted into the charging gun seat, and the controller 170 controls the brake mechanism 143 to hold tightly after receiving the brake signal, controls the coil on the stator to cut off the power to turn off the motor, and returns to the standby state.

[0072] In some embodiments of the present application, the controller 170 receives the rotational displacement of the rotating shaft 140 and controls the coil current on the stator according to the rotational displacement of the rotating shaft 140. The rotational displacement of the rotating shaft 140 represents the length of the wire rope released from the winding drum 130. That is, in fact, the controller 170 controls the coil current on the stator according to the length of the wire rope released from the winding drum 130.

[0073] Specifically, in the variable torque control mode, after receiving the line-releasing signal, the controller 170 controls the gun line management device 100 to enter the line-releasing state. In the line-releasing state, the controller 170 controls the coil on the brake mechanism 143 to be energized to release the brake mechanism 143. The controller 170 controls the coil on the stator to be energized to cause the shaft to generate torque and start to release the line. The torque generated by the shaft is in the second direction (i.e., the line-reeling direction, which is opposite to the direction of the force of the gun line on the shaft, thereby balancing the force of the gun line on the shaft). The torque generated by the shaft only needs to be slightly greater than the force of the gun line on the shaft. The user only needs to apply a slight force to pull the gun line, which reduces the difficulty of use for the user. The magnitude of the torque generated by the shaft when releasing the line is determined by the line-releasing torque curve. The line-releasing torque control curve is slightly lower than Figure 6 When releasing the line, a smaller release torque curve is used, and the user can start releasing the line with a little force. Figure 6 The difference between the shown shaft torque control curves decreases as the shaft rotation displacement increases. After receiving the charging signal, the controller 170 controls the gun line management device 100 to enter the charging state, the controller 170 controls the coil on the brake mechanism to de-energize so that the brake mechanism is tightened (after the brake mechanism tightens the shaft, the gun line is pulled to suspend and prevent it from falling to the ground), the controller 170 controls the coil on the stator to de-energize so that the shaft stops generating torque (when the brake mechanism is working, the stator coil can be de-energized to save energy), and the gun line is suspended. Of course, the brake mechanism can also be omitted, and the shaft can be used to generate reverse torque to suspend the gun line. After receiving the line-retrieving signal, the controller 170 controls the gun line management device 100 to enter the line-retrieving state, the controller 170 controls the coil on the brake mechanism to energize so that the brake mechanism is released, and the controller 170 controls the coil on the stator to energize so that the shaft generates torque and starts to reel in the gun line. The torque generated by the rotating shaft is in the second direction (i.e., the direction of winding, which is opposite to the direction of the force exerted by the gun line on the rotating shaft, thereby balancing the force exerted by the gun line on the rotating shaft). The torque generated by the rotating shaft needs to be slightly greater than the force exerted by the gun line on the rotating shaft, so that the line can be automatically wound without the user exerting any force, thereby reducing the difficulty of use for the user. The magnitude of the torque generated by the rotating shaft when winding is determined by the winding torque curve, and the winding torque control curve is slightly higher than Figure 6 When reeling in the line, a larger reeling torque curve is used, and the shaft will slightly drive the gun line to automatically reset. Figure 6The difference between the shown shaft torque control curves decreases as the shaft rotation displacement increases. After receiving the standby signal, the controller 170 controls the cable management device 100 to enter the standby state. The controller 170 controls the coil on the braking mechanism to be powered off so that the braking mechanism holds tightly. The controller controls the coil on the stator to be powered off so that the shaft stops generating torque, and the charging cable hovers. Of course, instead of using the braking mechanism, the shaft can also be used to generate a reverse torque to hover the charging cable.

[0074] In some other embodiments of the present application, the control method of the controller 170 includes a remote control signal and torque combined control method. The controller 170 receives the remote control signal and controls the coil current on the stator according to the remote control signal. The remote control signal can come from a remote control device. The remote control device can be set on the charging pile and manually started by the user. The remote control device can also be set on a mobile terminal, for example, a small program on the user's mobile phone, etc.

[0075] In some situations, for example, when the charging cable is located at a high place and the user cannot directly use it, the user can first manually start the remote control device to send a remote control signal. After receiving the remote control signal, the controller unloads the charging cable and controls the shaft to pay out the cable for a certain distance until the user gets the charging cable, and then switches to the torque control method to continue to cooperate with the user to pay out the cable. After the user finishes using the charging cable, the cable can be retracted directly by the torque control method.

[0076] In some embodiments of the present application, the actual cable retracting and paying out starting point is slightly longer than the theoretical origin, leaving a safety distance to prevent the cable from impacting the outlet. After each cable retracting and paying out, the origin is recalibrated. A safety distance is also reserved at the end of the cable. In case of an accident, for example, if the user stumbles, a certain length of cable can still be paid out.

[0077] The cable management device provided by the embodiments of the present application connects the cable reel and the charging cable with a cable. The torque of the inner rotor in the cable management device is almost balanced with the weight of the charging cable. In this way, when the user operates the charging, the user only needs to lift the weight of the charging cable to move the charging cable to the vehicle position for charging, greatly reducing the operation intensity and improving the charging experience.

[0078] The embodiments of the present application further provide a charging pile. Refer to Figure 7As shown in the figure, it includes: the gun line management device 100 as described above; the charging pile body 52, which is electrically connected to the gun line management device 100 through a wire 114; a gun line 51, one end of the gun line 51 is electrically connected to the charging pile body 52, one end of the cord of the gun line management device is fixed to the middle of the gun line, and the other end of the cord of the gun line management device is fixed to the winding disc; a charging gun 53, one end of the charging gun 53 is electrically connected to the other end of the gun line 51, and the other end of the charging gun 53 is used to connect to the charging interface of the electric vehicle; a charging gun seat 54, which is detachably connected to the charging gun 53.

[0081] In some embodiments of the present application, the gun line management device 100 is fixedly arranged on the top of the charging pile body 52. In this way, the length of the gun line 51 can be increased, so as to increase the probability that the charging pile can be connected to the electric vehicle through the gun line 51 and the charging gun 53, and further improve the usage frequency of the charging pile.

[0082] In some embodiments of the present application, an induction device is arranged on the charging gun 53 or the charging gun seat, and is communicatively connected to the controller. When the charging gun 53 is unplugged from the charging gun seat 54, the induction device sends a wire-releasing signal to the controller; when the charging gun 53 is unplugged from the charging interface of the electric vehicle, the induction device sends a wire-winding signal to the controller; when the charging gun 53 is inserted into the charging gun seat 54, the induction device sends a standby signal to the controller; when the charging gun 53 is inserted into the charging interface of the electric vehicle, the induction device sends a charging signal to the controller.

[0083] In some embodiments of the present application, the charging pile further includes: a remote control device that sends a remote control signal to the controller. The remote control device can be a physical device arranged on the charging pile body 52. The remote control device can also be a virtual program arranged on the user's mobile phone or the display software on the charging pile body 52.

[0084] The beneficial effects that may be brought about by the embodiments of the present application include, but are not limited to: under the control of the gun line management device 100 and / or the charging pile, after the charging gun 53 is used and during the charging process, the gun line can be kept from falling to the ground, thereby improving the service life of the gun line 51; and during the user's use process, it can assist the user in taking in or paying out the line, balance the gravity of the gun line 51, and improve the user experience.

[0085] For the gun line management device and the charging pile provided by the embodiments of the present application, a cord is used to connect the winding disc and the gun line. The torque of the inner rotor in the gun line management device is almost balanced with the weight of the gun line. In this way, when the user operates the charging, he only needs to lift the weight of the charging gun to control the movement of the charging gun to the vehicle position for charging, greatly reducing the operation intensity and improving the charging experience.
