Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of charging piles, in particular to a charging gun recycling device and a charging pile. BACKGROUND

[0002] In recent years, with the emphasis on environmental protection and sustainable development worldwide, electric vehicles have gradually become the mainstream trend of the automotive industry due to their environmental protection and high efficiency. Under this background, outdoor charging piles, as facilities for electric vehicle energy supply, have seen explosive growth in number.

[0003] Due to the differences in the matching distance between different types of electric vehicles and charging piles, in order to ensure that the charging piles can meet the charging needs of various electric vehicles, the length of the cable configured on the charging pile is generally longer. In actual use, when the charging pile is in an idle state, the excessively long cable can only be manually wound and stored in the protection box. This manual winding method is not only inefficient, but manual operation can also cause the cable to be wound irregularly, which can easily cause the cable to be worn and squeezed, thereby affecting the insulation and conductivity of the cable and increasing the safety risk. At the same time, the disordered cable will also bring inconvenience to the operator when used next time, and a lot of time will be spent on sorting, which reduces the efficiency of charging service.

[0024] The technical solutions disclosed by the various embodiments of the present application will be described in detail below in connection with the drawings.

[0025] Please refer to Figures 1 to 4 , Figure 1 A structural schematic diagram of a charging gun recycling device provided by an embodiment of the present application in a first state.

Figure 4 A structural schematic diagram of a charging gun recycling device provided by an embodiment of the present application.

[0026] As Figures 1 to 4As shown, the charging gun recycling device provided by the embodiment of the application comprises a cable storage mechanism 10, which comprises a storage box body 101, a first driving mechanism 102, a first rolling wheel 103, a second rolling wheel 104 and a fixed support 105. The storage box body 101 is provided with a first avoiding hole 1010, the fixed support 105 is arranged in the storage box body 101, the first rolling wheel 103 and the second rolling wheel 104 are movably arranged in the fixed support 105, the central axis of the first rolling wheel 103 is parallel to the central axis of the second rolling wheel 104, and the first rolling wheel 103 and the second rolling wheel 104 are oppositely and spacedly arranged in a direction perpendicular to the central axis of the first rolling wheel 103, so that a first clamping space is formed between the wheel surface of the first rolling wheel 103 and the wheel surface of the second rolling wheel 104, the cable of the charging gun passes through the first clamping space and is clamped between the wheel surface of the first rolling wheel 103 and the wheel surface of the second rolling wheel 104, and the first driving mechanism 102 is connected with the first rolling wheel 103.

[0027] In the case that the charging gun is in the first state, the cable 106 of the charging gun is in rolling cooperation with the wheel surface of the first rolling wheel 103 and the wheel surface of the second rolling wheel 104, so that at least part of the cable 106 extends out of the storage box body 101 through the first avoiding hole 1010.

[0028] In the case that the charging gun is in the second state, the first driving mechanism 102 drives the first rolling wheel 103 to rotate, so that the cable 106 of the charging gun is in rolling cooperation with the wheel surface of the first rolling wheel 103 and the wheel surface of the second rolling wheel 104 to collect the cable 106 into the storage box body 101.

[0029] Specifically, the storage box body 101 can be a square box body, a first avoiding hole 1010 can be arranged in a side wall of the storage box body 101, and the cable of the charging gun can pass in and out of the storage box body 101 through the first avoiding hole 1010. The first avoiding hole 1010 can be circular, and the diameter of the first avoiding hole 1010 is greater than the diameter of the cable of the charging gun. The first avoiding hole 1010 can also be square in the figure to reduce the friction between the cable of the charging gun and the first avoiding hole 1010 and prolong the service life of the cable of the charging gun.

[0030] Further, the first driving mechanism 102 can be a motor, which is inserted into the shaft hole of at least one of the first rolling wheel 103 and the second rolling wheel 104 through a shaft coupling. In the process of rotating the motor, the first rolling wheel 103 is driven to rotate, so that the cable of the charging gun head moves with the rotation of the first rolling wheel 103.

[0031] Further, the first rolling wheel 103 and the second rolling wheel 104 can each adopt a cylindrical structure, which includes a wheel surface with a width slightly larger than the diameter of the cable, so as to ensure that the cable can be stably clamped between the wheel surfaces of the first rolling wheel 103 and the second rolling wheel 104. In order to increase the friction and anti-skid performance of the wheel surfaces of the first rolling wheel 103 and the second rolling wheel 104, as an optional embodiment of the present application, the wheel surface of the first rolling wheel 103 and the wheel surface of the second rolling wheel 104 are each provided with an anti-skid structure 115. The anti-skid structure 115 can be high-elasticity rubber or silicone, and the surface is provided with fine anti-skid lines. The elasticity of the rubber material can form flexible wrapping on the cable, so as to avoid extrusion damage caused by hard contact. The anti-skid lines can enhance the friction with the surface of the cable, prevent slipping during the winding and unwinding process, and ensure the synchronization of the movement of the cable. The anti-skid structure 115 can be a protrusion arranged at intervals on the wheel surface of the first rolling wheel 103 and the wheel surface of the second rolling wheel 104, so as to increase the friction with the cable.

[0032] Further, in the connection of the first rolling wheel 103 and the second rolling wheel 104 with the fixed support 105, the two ends of the central shaft of the first rolling wheel 103 and the second rolling wheel 104 are movably connected to the preset mounting holes of the fixed support 105 through bearings. The bearings can greatly reduce the rotation resistance of the first rolling wheel 103 and the second rolling wheel 104, so as to ensure that the first driving mechanism 102 can realize smooth rotation when driving the cable, and improve the cable recovery efficiency and reliability. Further, the fixed support 105 can be further provided with a guide rail. One end of the first rolling wheel 103 can be fixedly connected with the first driving mechanism 102 through a shaft coupling. The other end of the first rolling wheel 103 can be inserted into the shaft hole thereof through a connecting shaft. One end of the connecting shaft can be fixedly connected with the guide rail, and the connecting shaft is movably connected with the shaft hole, so that the first rolling wheel 103 can rotate relative to the connecting shaft and the shaft coupling. The two ends of the central shaft of the second rolling wheel 104 can be inserted into the shaft hole through the connecting shaft. One end of the connecting shaft can be fixedly connected with the guide rail, and the other end of the connecting shaft can be movably connected with the shaft hole of the second rolling wheel 104. When the first driving mechanism 102 drives the first rolling wheel 103 to rotate, the second rolling wheel 104 can be passively rotated with the movement of the cable, so as to form a cooperative connection.

[0033] Optionally, as an optional embodiment of the present application, the charging gun recovery device further comprises an adjusting mechanism 107, which is arranged in the storage box body 101 and fixed to the fixed support 105. The adjusting mechanism 107 is connected with the second rolling wheel 104, and adjusts the distance between the first rolling wheel 103 and the second rolling wheel 104 according to the diameter of the cable 106, so that the wheel surface of the first rolling wheel 103 and the wheel surface of the second rolling wheel 104 clamp the cable 106.

[0034] Specifically, the adjusting mechanism 107 can be fixed on the fixed support 105 to adjust the axial position of the second rolling wheel 104, so that the clamping space formed by the wheel surface of the first rolling wheel 103 and the wheel surface of the second rolling wheel 104 can adapt to cables of different diameters. When the cable is thicker, the second rolling wheel 104 can be moved upward by the adjusting mechanism 107 to increase the distance between the wheel surface of the first rolling wheel 103 and the wheel surface of the second rolling wheel 104. When the cable is thinner, the second rolling wheel 104 can be moved downward by the adjusting mechanism 107 to reduce the distance between the wheel surface of the first rolling wheel 103 and the wheel surface of the second rolling wheel 104, so that the clamping force between the wheel surface of the first rolling wheel 103 and the wheel surface of the second rolling wheel 104 can be kept stable. The adaptability of the rolling wheels to cables of different specifications is further improved, and the versatility of the entire storage mechanism is enhanced.

[0035] Optionally, as an optional embodiment of the present application, the adjusting mechanism 107 comprises a spring 1070, a guide rod 1071 and a sliding block 1072. The guide rod 1071 is arranged on the fixed support 105, the spring 1070 is sleeved on the outer side of the guide rod 1071, the first end of the spring 1070 is connected with the fixed support 105, the second end of the spring 1070 is connected with the sliding block 1072, the fixed support 105 is provided with a guide rail 1050, the extension direction of the guide rail 1050 and the extension direction of the guide rod 1071 are both parallel to the direction from the center of the first rolling wheel 103 to the center of the second rolling wheel 104. The sliding block 1072 is sleeved on the guide rod 1071 in a sliding manner, the sliding block 1072 is in sliding fit with the guide rail 1050 and is connected with the second rolling wheel 104, and the first rolling wheel 103 and the second rolling wheel 104 clamp the cable 106 under the elastic force of the spring 1070.

[0036] Specifically, the spring 1070 can be compressed or stretched as the sliding block 1072 moves on the guide rod 1071. When the cable of the charging gun is thicker, the second rolling wheel 104 is lifted, the sliding block 1072 slides upward on the guide rod 1071 so that the spring 1070 is in a compressed state and exerts an elastic force downward on the second rolling wheel 104, which can not only increase the distance between the wheel faces of the first rolling wheel 103 and the second rolling wheel 104, but also compress the cable. In this way, when the cable 106 passes between the first rolling wheel 103 and the second rolling wheel 104, the elastic force of the spring 1070 will push the second rolling wheel 104 to approach the first rolling wheel 103 through the sliding block 1072, thereby achieving automatic clamping of the cable 106. If there is a difference in the diameters of the cable 106, when the thicker cable enters the clamping space, it will push the second rolling wheel 104 to move the sliding block 1072 along the guide rod 1071 and the guide rail 1050 away from the first rolling wheel 103, at this time the spring 1070 is compressed and the elastic force increases, still maintaining a stable clamping force; when the thinner cable enters, the spring 1070 will release the elastic potential energy and pull the second rolling wheel 104 to approach the first rolling wheel 103, avoiding slipping caused by loose clamping. This self-adaptive adjustment structure does not require manual intervention, can adapt to the clamping needs of cables of different specifications, and can always ensure the stability of the cable during winding and unwinding, further improving the reliability and universality of the entire storage mechanism.

[0037] Optionally, as an optional embodiment of the present application, the charging gun recycling device further comprises a measuring mechanism 108, which is arranged on the fixed support 105. The measuring mechanism 108 is used to measure the first length of the cable extending out of the storage box body 101 and the second length of the cable 106 retracting into the storage box body 101.

[0038] Specifically, the measuring mechanism 108 is arranged on the fixed support 105, and is configured to measure the first length of the cable wire extending out of the storage box 101 and the second length of the cable wire 106 retracting into the storage box 101. The measuring mechanism 108 can be an encoder which is connected to the central shaft of the first rolling wheel 103 or the second rolling wheel 104, and can accurately record the number of rotations of the first rolling wheel 103 or the second rolling wheel 104. Since the circumference of the first rolling wheel 103 or the second rolling wheel 104 is fixed, the movement distance of the cable wire can be calculated by the number of rotations, and then the first length and the second length can be obtained. When the charging gun is in the first state, i.e., the charging gun is in use, the cable wire extends outwards, and the encoder rotates forward with the first rolling wheel 103 and the second rolling wheel 104, and the number of rotations is accumulated in real time and converted into the first length. The length information can be fed back to the control module, so that the user or the system can know the extension of the cable wire, and overstretching can be avoided. When the charging gun is in the second state, i.e., the charging gun is used up, the cable wire retracts inwards, and the encoder rotates reversely with the rolling wheel, and the number of rotations is also accumulated and converted into the second length. The control module can determine whether the cable wire has been completely retracted into the storage box according to the length, and if the preset complete retraction length is reached, the first driving mechanism 102 can be controlled to stop working, so as to prevent over-retraction from damaging the cable wire.

[0039] Further, in order to avoid interference with the work of the first rolling wheel 103 and the second rolling wheel 104 and affect the winding efficiency, the embodiment of the present application provides another measuring mechanism. Optionally, as an optional embodiment of the present application, the measuring mechanism 108 comprises a mounting frame 1080, a first detection roller 1081, a second detection roller 1082 and an encoder 1083. The encoder 1083 is connected to the central shaft of the first detection roller 1081 to monitor the number of rotations of the first detection roller 1081, and determines the first length and the second length based on the number of rotations and the circumference of the first detection roller 1081.

[0040] The first detection roller 1081 and the second detection roller 1082 are movably arranged on the mounting frame 1080, the central axes of the first detection roller 1081 and the second detection roller 1082 are parallel, and in a direction perpendicular to the central axis of the first detection roller 1081, the first detection roller 1081 and the second detection roller 1082 are oppositely and spacedly arranged, so that a second clamping space is formed between the wheel surface of the first detection roller 1081 and the wheel surface of the second detection roller 1082, and the cable wire 106 of the charging gun passes through the second clamping space and is clamped between the wheel surface of the first detection roller 1081 and the wheel surface of the second detection roller 1082.

[0041] Specifically, the mounting frame 1080 is fixedly installed on the fixed support 105 as a carrier of the measuring mechanism, and is arranged at a position close to one side of the first avoiding hole 1010, so as to ensure that the cable can accurately pass through the detection area of the measuring mechanism during the extension or retraction process. The first detection roller 1081 and the second detection roller 1082 are movably installed on the mounting frame 1080 through bearings, the center axes of the two rollers are kept parallel, and the two rollers are oppositely and spacedly arranged in a direction perpendicular to the center axis of the first detection roller 1081, so that the second clamping space formed by the two rollers is arranged on the same straight line as the first clamping space formed by the first rolling wheel 103 and the second rolling wheel 104, so as to ensure that the cable can smoothly pass through the two clamping spaces in sequence, and the measurement accuracy is not affected by the path deviation.

[0042] The wheel surface of the first detection roller 1081 and the second detection roller 1082 can be provided with an anti-skid part, for example, the anti-skid part is made of high-elastic rubber of anti-skid material, and the wheel surface width is matched with the diameter of the cable, so that the cable can be closely attached to the surface of the cable when the cable passes through the second clamping space. When the cable moves, the first detection roller 1081 and the second detection roller 1082 are driven to rotate synchronously, and the encoder is directly connected with the center axis of the first detection roller 1081, so that the rotation number and the rotation direction of the first detection roller 1081 can be captured in real time. Combined with the fixed circumference of the first detection roller 1081, the moving length of the cable can be accurately obtained through the calculation method of “rotation number × circumference”, that is, the first length is obtained when the cable is extended outward, and the second length is obtained when the cable is retracted inward. In this way, the design of the double detection rollers can further improve the measurement stability. On the one hand, the second detection roller 1082 forms a reverse clamping force on the cable, so that the cable is always in close contact with the first detection roller 1081, and the measurement error caused by slipping is avoided. On the other hand, the double rollers can limit the lateral deviation of the cable during the detection process, so that the moving direction of the cable is consistent with the rotation direction of the rollers, and the accuracy of the length measurement is further improved. The encoder transmits the measured length data to the control module in real time, so as to provide a basis for the control of the charging gun. For example, when the second length reaches the maximum length that can be accommodated in the storage box 101, the control module immediately instructs the first driving mechanism 102 to stop working, so as to realize the accurate recovery of the cable. When the first length reaches the maximum allowed extension length, the control module immediately instructs the first driving mechanism 102 to stop working, so as to realize the accurate extension of the cable.

[0043] Optionally, as an optional embodiment of the present application, the charging gun recovery device further comprises a box body 109, a door body 110 and a locking mechanism 111, the door body 110 is movably connected with the box body 109 through a side hinge, the cable storage mechanism 10 and the locking mechanism 111 are both arranged in the box body 109, and the locking mechanism 111 is arranged on one side of the first avoiding hole 1010, the bottom of the box body 109 is provided with a second avoiding hole 1090, and the cable 106 enters the storage box body 101 through the first avoiding hole 1010 and the second avoiding hole 1090.

[0044] When the cable 106 is retracted into the storage box body 101 and the gun head enters the locking position of the locking mechanism 111 through the second avoiding hole 1090, the locking mechanism 111 is locked with the gun head of the charging gun to lock the gun head.

[0045] Specifically, the box body 109 can be made of high-strength metal material, which has good waterproof, dustproof and impact resistance performance, can provide a stable working environment for the internal cable storage mechanism 10, the locking mechanism 111 and other components, and can effectively resist the damage of wind, rain, sunlight and external force impact on the internal components, especially in the outdoor charging pile scene. The internal space layout is reasonably planned to ensure that the cable storage mechanism 10 and the locking mechanism 111 do not interfere with each other after installation, and sufficient space is reserved for the extension and retraction of the cable. The second avoiding hole 1090 is arranged at the bottom of the box body 109, and the hole diameter is slightly larger than the diameter of the charging gun head, which can ensure that the gun head and the cable can smoothly pass into the box body, and can reduce the possibility of foreign matters entering the inside of the box body 109.

[0046] The door body 110 is connected with the box body 109 through a side hinge, which can be flexibly opened and closed, and facilitates the maintenance, maintenance or replacement of the components in the box body 109. When the door body 110 is closed, a sealing rubber strip is arranged between the door body 110 and the box body 109, which can further enhance the sealing performance of the box body 109, and at the same time, a door lock can be arranged on the door body 110, which is locked in the non-maintenance state to prevent irrelevant personnel from opening it at will, and to ensure the safety of the internal equipment.

[0047] The locking mechanism 111 is arranged on one side of the first avoiding hole 1010 close to the second avoiding hole 1090, and can include a clamping groove, an electromagnetic lock or a mechanical lock catch matched with the head of the charging gun. When the measuring mechanism 108 detects that the cable 106 has been completely withdrawn into the storage box 101, and the head of the charging gun enters the locking position of the locking mechanism 111 through the second avoiding hole 1090, the control module triggers the locking mechanism 111 to work. If it is an electromagnetic lock structure, the electromagnetic lock will generate a magnetic force to firmly adsorb the head in the clamping groove. If it is a mechanical lock catch, the lock catch will automatically pop up and lock the groove on the head to achieve locking cooperation. This locking can stably fix the head inside the box 109, avoid the head from being pulled out of the box 109 or shaking when the outside is vibrated or slightly collided, protect the head from being damaged, and ensure the whole recycling device to be clean and orderly. When the charging gun needs to be used, the user can unlock the charging pile through scanning the code and the like. After the control module receives the unlocking instruction, the locking mechanism 111 is controlled to release the head. At this time, the first driving mechanism 102 can drive the cable 106 to extend outward, so as to facilitate the user to take the head and pull the cable.

[0048] Optionally, as an optional embodiment of the present application, the locking mechanism 111 includes a second driving mechanism, a locking body 1110 and a lock tongue 1111. The locking body 1110 is arranged in the box 109, and the lock tongue 1111 is movably arranged in the locking body 1110 and connected with the second driving mechanism. A locking hole 112 is arranged on the head of the charging gun.

[0049] In the case that the cable 106 is withdrawn into the storage box 101, the second driving mechanism drives the lock tongue 1111 to insert into the locking hole 112 to lock and cooperate with the head of the charging gun.

[0050] Specifically, the locking body 1110 can adopt a block structure and is fixed in the box 109 close to the second avoiding hole 1090 by bolts and the like. The locking body 1110 includes a lock tongue accommodating portion 11101 and a limiting portion 11102 matched with the lock tongue accommodating portion. The lock tongue accommodating portion 11101 is internally provided with a channel for the lock tongue 1111 to move. The extension direction of the channel is consistent with the axis direction of the locking hole 112 when the head enters the locking position, so as to ensure that the lock tongue 1111 can accurately align with the locking hole 112. The limiting portion 11102 is provided with a limiting hole 11103, which is coincident with the extension direction of the channel, so as to ensure that the lock tongue 1111 enters the limiting hole 11103 after penetrating through the locking hole 112, and the purpose of locking the head is achieved. It is worth noting that the length of the lock tongue should be greater than the distance between the lock tongue accommodating portion 11101 and the limiting portion 11102 matched with the lock tongue accommodating portion, so as to ensure that the lock tongue can connect the lock tongue accommodating portion and the limiting portion 11102.

[0051] The end of the lock tongue 1111 can be designed as a taper or an arc shape, which is convenient for being inserted into the locking hole 112 and the limiting hole 11103 of the limiting part 11102. The tail of the lock tongue 1111 is connected with the second driving mechanism. The second driving mechanism can be selected from a motor, an air cylinder or an electromagnet. If the second driving mechanism is a motor, the rotary motion can be converted into the linear motion of the lock tongue 1111 through a screw nut structure. If the second driving mechanism is an air cylinder or an electromagnet, the lock tongue 1111 can be directly driven to move linearly.

[0052] When the cable 106 is retracted into the storage box 101, the measuring mechanism 108 feeds back a signal to the control module. After the control module confirms that the gun head has reached the locking position, the control module sends an instruction to the second driving mechanism. The second driving mechanism is then started to drive the lock tongue 1111 to extend along the channel in the locking body 1110 and to be accurately inserted into the locking hole 112 and the limiting hole 11103 on the gun head, so as to form a firm locking cooperation with the gun head of the charging gun. At this time, the movement degree of freedom of the gun head is limited by the lock tongue 1111, and the gun head cannot be pulled out of the box 109. When the charging gun needs to be used, the control module receives an unlocking operation instruction from the user, and then controls the second driving mechanism to move reversely to drive the lock tongue 1111 to retract from the locking hole 112 and the limiting hole 11103, so as to release the locking of the gun head. Subsequently, the first driving mechanism 102 drives the cable to extend, and the user can smoothly take out the gun head to perform the charging operation. The locking mechanism with the above structure is accurate in operation and reliable in locking, and can effectively guarantee the stability and safety of the charging gun in the non-use state.

[0053] Optionally, as an optional embodiment of the present application, the charging gun recycling device further comprises an electric energy meter 113 and a control module 114. The electric energy meter 113 and the control module 114 are arranged in the box 109, and the control module 114 is connected with the electric energy meter 113. The control module 114 is connected with the first driving mechanism 102, the second driving mechanism, the measuring mechanism 108 and the locking mechanism 111 respectively, so as to control the first driving mechanism 102, the second driving mechanism, the measuring mechanism 108 and the locking mechanism 111.

[0054] Specifically, the electric energy meter 113 is usually installed in the box 109 near the power input end, so as to facilitate the measurement of the electric energy passing through the cable during the charging process. The electric energy meter 113 can accurately record the electric energy consumed by the charging gun when charging the electric vehicle, so as to provide accurate data basis for the electric fee settlement. Meanwhile, after the electric energy meter 113 is connected with the control module 114, the electric energy meter 113 can transmit the measured electric energy data to the control module 114 in real time. The control module 114 can store, process and upload these data, so as to facilitate the user to query the charging electric energy and fee information through a related terminal.

[0055] The control module 114 is installed in a position inside the box 109 that is convenient for wiring and signal transmission, and its internal components include a microprocessor, a memory, an input / output interface, and the like. In addition to being connected to the electric energy meter 113, the control module 114 is also connected to the first driving mechanism 102, the second driving mechanism, the measuring mechanism 108, and the locking mechanism 111, and the like, to form a complete control system. When the user needs to take the charging gun, the user can issue an instruction to the control module 114 by operating the button or scanning the code on the charging pile, and after the control module 114 receives the instruction, it will first send a signal to the second driving mechanism to control the locking tongue 1111 to retract from the locking hole 112 to release the locking of the gun head. Then, the control module 114 controls the first driving mechanism 102 to start, drives the first rolling wheel 103 and the second rolling wheel 104 to rotate, so that the cable 106 extends out of the box 109 through the first avoiding hole 1010 and the second avoiding hole 1090, and at the same time, the measuring mechanism 108 feeds back the extension length of the cable 106 to the control module 114 in real time, and when the extension length reaches the preset length, the control module 114 controls the first driving mechanism 102 to stop working.

[0056] When the charging is completed and the user returns the gun head to the original position, the measuring mechanism 108 detects that the cable 106 is retracted into the storage box 101 and the gun head reaches the locking position, and then transmits a signal to the control module 114, and the control module 114 immediately controls the first driving mechanism 102 to stop working, and sends an instruction to the second driving mechanism to drive the locking tongue 1111 to insert into the locking hole 112 to complete the locking of the gun head. In addition, the control module 114 can also monitor the working state of each component, and if a component fails, such as the first driving mechanism 102 being stuck, the locking tongue 1111 being unable to normally extend and retract, and the like, the control module 114 will promptly issue an alarm signal to remind the staff to repair and ensure the stable operation of the entire device.

[0057] The cable is always in a stable clamping state in the winding and unwinding process through the clamping space formed by the first rolling wheel and the second rolling wheel, and is moved stably through cooperation of the rotation of the rolling wheels, so that problems such as disorderly winding and knotting of the cable during storage of the charging gun are avoided, the cable is orderly wound and unwound, the orderliness of the cable during storage of the charging gun is improved, the user does not need to spend time on arranging the cable, and the operation efficiency is improved. Further, since the cable is in rolling cooperation with the wheel surface of the rolling wheel in the winding and unwinding process, instead of being hard dragged or rubbed, the pulling force and friction force suffered by the surface and internal core of the cable are reduced. Meanwhile, the storage box body can store the cable in a non-use state, avoids erosion of the cable caused by external factors such as sun exposure, rain, bumping or stepping in a long-term exposure state, and significantly improves the durability and safety of the cable. When the charging gun is in the second state, the first driving mechanism can automatically drive the rolling wheel to rotate to realize the retraction of the cable, without manual winding, so that the labor cost is saved and the storage efficiency is improved.

[0058] Further, the embodiment of the present application further provides a charging pile, which comprises a charging pile body and the charging gun recovery device mentioned in the above embodiment; the charging pile body comprises a charging gun, and the charging gun recovery device is used for recovering the cable of the charging gun.

[0060] In the above embodiment, the difference between each embodiment is mainly described, and the optimization features different between each embodiment can be combined to form a more optimal embodiment as long as they are not contradictory. Considering the brevity of the text, it will not be described here.
