Description

A liquid-cooled outdoor charging pile

Technical Field

The present invention relates to the technical field of charging piles, and in particular to a liquid-cooled outdoor charging pile.

Background technique

The function of the charging pile is similar to that of the gas pump in a gas station. It can be fixed on the ground or on the wall and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and residential parking lots or charging stations. It can charge various types of electric vehicles according to different voltage levels, and the liquid-cooled charging pile is one of them.

As we all know, the general structure of a charging pile is a slightly larger control box plus a long cable. The same is true for portable chargers. This will cause a problem during use. The length or shortness of the charging pile cable has both advantages and disadvantages. The longer the cable, the farther it can be pulled, and the more convenient it will be for charging. The longer the cable, the more problems it will cause. After each use, the cable needs to be rearranged, and it needs to be wound around the charging pile and placed. If the cable is not arranged, the cable may be crushed by the tire of the charging car, causing damage to the line. For this reason, the cable is currently stored by electric winding, placed inside the charging pile, and the cable is cleaned while being stored.

However, some existing charging piles fix the charging gun on the charging pile when the cable is reeled in, which causes a torque to be generated when the cable is reeled in, causing the cable at the charging gun end to be severely twisted and deformed. When the torque is too large, the cable will be torn and damaged, thereby affecting the normal service life of the cable.

Summary of the invention

In view of the deficiencies in the prior art, the present invention provides a liquid-cooled outdoor charging pile, which has the advantages of removing torque, restoring the charging cable to normal, and increasing the service life of the charging cable, thereby ensuring the safe use of the charging pile, etc., and solves the problem that some existing charging piles fix the charging gun on the charging pile when winding the cable, which causes a torque to be generated when the cable is wound, causing the cable at the end of the charging gun to be severely twisted and deformed. When the torque is too large, the cable will be torn and damaged, thereby affecting the normal service life of the cable.

In order to solve the technical problem that some existing charging piles fix the charging gun on the charging pile when winding the cable, which results in a torsional force when the cable is wound, causing the cable at the end of the charging gun to be severely twisted and deformed.

Detailed ways

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

Please refer to Figures 1 to 9, a liquid-cooled outdoor charging pile includes a charging pile shell 1, a storage mechanism 3, a cleaning mechanism 4 and a force unloading mechanism 5. The charging pile shell 1 is provided with a host room 11 and a storage room 12 on both sides thereof. A charging module 1101 is provided in the host room 11. A charging cable 1105 is connected to the charging module 1101. The charging cable 1105 passes from the host room 11 into the storage room 12. The storage room 12 is provided with a storage mechanism 3 and a cleaning mechanism 4. The storage mechanism 3 is used to wind and store the charging cable 1105. The cleaning mechanism 4 is used to wind the charging cable 1105 to The storage mechanism 3 cleans the dust on the surface of the charging cable 1105 before use. The charging cable 1105 is stored and sorted by the storage mechanism 3 and then passes through the cleaning mechanism 4 to the outside of the storage chamber 12. The end of the charging cable 1105 outside the storage chamber 12 is fixedly connected to the charging gun 2. A charging gun storage rack 1201 is provided outside the storage chamber 12. The force unloading mechanism 5 is installed on the charging gun storage rack 1201. The charging gun 2 is inserted into the charging gun storage rack 1201 after use. The force unloading mechanism 5 can rotate with the charging gun 2 to unload the torque generated by the storage mechanism 3 during the retraction of the charging cable 1105.

When in use, first remove the charging gun 2 from the charging gun storage rack 1201, then the storage mechanism 3 releases a charging cable 1105 of appropriate length and pulls it out from the storage chamber 12, so that the charging gun 2 can be docked with the electric vehicle that needs to be charged. After the charging gun 2 is docked, the charging pile charges it. During this process, most of the charging cable 1105 exposed to the outside is in contact with the ground, and its surface will inevitably adhere to some dust, sewage and other dirt. After the electric vehicle is charged, remove the charging gun 2 from the electric vehicle, insert the charging gun 2 back into the charging gun storage rack 1201, and then, store it. The storage mechanism 3 in the chamber 12 begins to store the pulled out charging cable 1105. At the same time, the cleaning mechanism 4 can work together with the storage mechanism 3 to clean the stored charging cable 1105 and remove the dirt on the charging cable 1105. During the storage process, the charging cable 1105 will generate torque. After the torque reaches a certain intensity, the charging cable 1105 that has not been stored will twist and become hard and straight. At this time, the unloading mechanism 5 and the charging gun 2 rotate under the action of the torque, which can unload the torque generated by the charging cable 1105, thereby completing the storage of the charging cable 1105.

Furthermore, the unloading mechanism 5 includes a sleeve 51, an unloading shaft 52, a fixing member 53 and an unloading spring 54. The sleeve 51 is fixedly installed inside the charging gun storage rack 1201, and the opening of the sleeve 51 faces the storage chamber 12. A plurality of slots 5101 are provided on the opening of the sleeve 51. The slots 5101 are evenly distributed in a circular shape on the sleeve 51. The unloading shaft 52 is rotatably installed in the sleeve 51, and a plurality of guide rods 5201 are provided at one end of the unloading shaft 52. The fixing member 53 is movably installed in the sleeve 51, and The guide rod 5201 is coaxially slidably connected with the unloading shaft 52, and one end of the fixing member 53 is provided with a plurality of clamping blocks 5301, and the plurality of clamping blocks 5301 are engaged with the plurality of clamping grooves 5101 in a one-to-one correspondence. The unloading spring 54 is installed on the outside of the fixing member 53 and the unloading shaft 52, and the two ends of the unloading spring 54 are respectively fixedly connected with the front end of the fixing member 53 and the rear end of the unloading shaft 52. The fixing member 53 is provided with a socket 5302, and the front end of the charging gun 2 is fixed to the fixing member 53 by being engaged with the socket 5302.

In the process of the storage mechanism 3 winding and retracting the charging cable 1105, the charging cable 1105 at the tail end of the charging gun 2 is twisted and tightened to generate tension, which gradually pulls the fixing member 53 out of the sleeve 51 through the charging gun 2, so that the block 5301 on the fixing member 53 is gradually separated from the slot 5101. At the same time, as the fixing member 53 is stretched, the unloading spring 54 fixedly connected to the fixing member 53 and the unloading shaft 52 will be stretched by the fixing member 53. When the storage motor 31 is paused, the block 5301 is completely separated from the slot 5101. 01 and the restriction of the slot 5101, the twisted and taut charging cable 1105 applies a torque to the fixing part 53 to rotate it through the charging gun 2, and the fixing part 53 drives the unloading shaft 52 to rotate in the sleeve 51 through the guide rod 5201 to remove the torque. After the torque is removed, the charging cable 1105 will be relaxed and restored to its natural state, no longer twisted and tight, so that the fixing part 53 loses tension and torque, so that the unloading spring 54 pulls the fixing part 53 back into the sleeve 51, and makes the block 5301 on the fixing part 53 re-engage with the slot 5101, so that the charging gun 2 is fixed again.

Furthermore, the storage mechanism 3 includes a storage motor 31 and a take-up roller 32. The storage motor 31 is arranged at the top of the storage chamber 12, and the take-up roller 32 is arranged below the storage motor 31. The upper end of the take-up roller 32 is fixedly installed in the storage chamber 12, and the lower end thereof is suspended in the storage chamber 12. A turntable 3201 is coaxially rotatably installed on the upper end of the take-up roller 32. A transmission gear 34 is coaxially fixedly connected to the top of the turntable 3201. A winding rod 3202 is fixedly connected to the lower surface of the turntable 3201. The winding rod 3202 is arranged parallel to one side of the take-up roller 32. The turntable 3201 can drive the winding rod 3202 to rotate around the take-up roller 32.

A driving gear 35 is coaxially fixedly connected to the output shaft of the storage motor 31, and the driving gear 35 is meshed with the transmission gear 34. A spiral groove 3203 is provided on the take-up roller 32, and a take-up clamp 33 is slidably fitted on the winding rod 3202. The charging cable 1105 is slidably assembled on the take-up clamp 33 to achieve the limited clamping of the charging cable 1105 by the take-up clamp 33. A limiting rod 3301 is provided on the lower side of the take-up clamp 33, and one end of the limiting rod 3301 is slidably fitted in the spiral groove 3203.

When the storage mechanism 3 releases the charging cable 1105, the storage motor 31 rotates in the opposite direction, and drives the transmission gear 34 meshing with it through the driving gear 35, so that the transmission gear 34 drives the turntable 3201 to rotate clockwise, and the rotating turntable 3201 drives the winding rod 3202 and the take-up clamp 33 to rotate around the take-up roller 32. During this process, the limit rod 3301 on the take-up clamp 33 will slide along the spiral direction of the spiral groove 3203, driving the take-up clamp 33 to slide upward on the winding rod 3202, so that the take-up clamp 33 releases the charging cable 1105 from the take-up roller 32 from bottom to top along the spiral direction of the spiral groove 3203. At the same time, the charging gun 2 is pulled to release the released charging cable 1105. 105 is pulled out from the storage chamber 12, and after a suitable length is pulled out, the storage motor 31 is turned off to stop releasing the charging cable 1105; when storing, the storage motor 31 starts in the forward direction, and drives the transmission gear 34 meshing with it through the driving gear 35, so that the transmission gear 34 drives the turntable 3201 to rotate, and the rotating turntable 3201 drives the winding rod 3202 and the take-up clamp 33 to rotate around the take-up roller 32. During this process, the limit rod 3301 on the take-up clamp 33 will slide along the spiral direction of the spiral groove 3203, driving the take-up clamp 33 to slide downward on the winding rod 3202, allowing the take-up clamp 33 to wind the charging cable 1105 onto the take-up roller 32 from top to bottom along the spiral direction of the spiral groove 3203.

Furthermore, the cleaning mechanism 4 includes a cleaning box 41, a cleaning shaft 42, a rotating shaft 43, a transmission motor 45, a sub-bevel gear 46 and a collecting box 47. The cleaning box 41 is fixedly installed in the storage chamber 12 and is located on one side below the storage mechanism 3. A pair of cleaning shafts 42 and a pair of rotating shafts 43 are rotatably installed inside the cleaning box 41. Four bearing seats 44 distributed in a rectangular shape are arranged on both side walls of the cleaning box 41, and the bearing seats 44 located on the upper side are slidably assembled on the side walls of the cleaning box 41. The cleaning shaft 42 and the rotating shaft 43 are both rotatably assembled on the bearing seats 44. A disengagement spring 4401 is connected between the top of the bearing seats 44 located on the upper side and the top wall of the cleaning box 41. A cable channel 4101 is opened on the side wall surface of the cleaning box 41. The charging cable 1105 extending from the storage mechanism 3 passes through the two rotating shafts 43 and the two cleaning shafts 42 in turn through the cable channel 4101, and extends to the outside of the cleaning box 41 and the storage chamber 12 in turn.

In the process of the take-up clamp 33 of the winding rod 3202 winding the charging cable 1105 around the recovery wire roller 32, a torque is generated and concentrated on the charging cable 1105 at the tail end of the charging gun 2 outside the storage chamber 12. As the take-up roller 32 reels more charging cables 1105, the charging cable 1105 at the tail end of the charging gun 2 is subjected to a greater torque. After the torque reaches a certain strength, the charging cable 1105 that has not been stored is gradually twisted and tightened due to the torque. At this time, since the charging cable 1105 is not completely retracted, and the charging cable 1105 is wound on the take-up roller 32 from top to bottom, the position of the charging cable 1105 at the bottom in the storage chamber 12 is higher than the charging cable 1105 connected to the charging gun 2 outside the storage chamber 12, so that a straight line inclined from the inside of the storage chamber 12 to the outside of the storage chamber 12 is gradually formed under continuous storage. At this time, the tight charging cable 1105 in the cleaning box 41 will be tilted due to the tilt. The cleaning shaft 42 and the rotating shaft 43 above it are pushed upward, so that the disengagement spring 4401 between the bearing seat 44 and the cleaning box 41 is compressed. At the same time, the cleaning shaft 42 located on the upper side of the cleaning box 41 will bring the spur gear 4202 thereon to disengage from the spur gear 4202 on the cleaning shaft 42 on the lower side, so that the charging cable 1105 that is twisted and tightened due to the torsion is no longer cleaned by the cleaning mechanism 4. As the torsion is removed, the charging cable 1105 returns to its natural state and is no longer twisted and tightened. The charging cable 1105 no longer pushes the bearing seat 44 upward through the rotating shaft 43, so that the bearing seat 44 loses the upward thrust on the disengagement spring 4401, and the compressed disengagement spring 4401 of the bearing seat 44 is pushed downward, thereby resetting the cleaning shaft 42 and the rotating shaft 43 on the bearing seat 44, and the cleaning shaft 42 located on the upper side of the cleaning box 41 will bring the spur gear 4202 thereon to mesh with the spur gear 4202 on the cleaning shaft 42 on the lower side.

Furthermore, a cleaning brush 4201 and a cleaning cotton 4301 are respectively provided on the two cleaning shafts 42 and the two rotating shafts 43. The cleaning brush 4201 is used to brush and clean the dust on the surface of the charging cable 1105 retracted by the storage mechanism 3, and the cleaning cotton 4301 is used to wipe and clean the surface of the charging cable 1105 after brushing and cleaning. The area where the cleaning brush 4201 is located is separated by a partition to form a cleaning chamber 4102, and a detachable collection box 47 is provided on the lower side of the cleaning chamber 4102.

Furthermore, a transmission motor 45 is provided at the bottom of the cleaning box 41, and the output shaft of the transmission motor 45 slides through the cleaning box 41, and a main bevel gear 4501 is coaxially fixedly connected thereto. A secondary bevel gear 46 is coaxially fixedly connected to the cleaning shaft 42 located at the lower side of the cleaning box 41, and the secondary bevel gear 46 is meshed with the main bevel gear 4501. A spur gear 4202 is provided at one end of the two cleaning shafts 42. When the charging cable 1105 has no torque, the spur gears 4202 on the two cleaning shafts 42 are meshed. When the charging cable 1105 generates a certain torque, the spur gear 4202 located above will disengage from the spur gear 4202 located below.

Among them, when the charging cable 1105 is retracted, the transmission motor 45 connected to the output shaft of the storage motor 31 will be driven by the storage motor 31, and the rotating transmission motor 45 will rotate together with the main bevel gear 4501 thereon, and the secondary bevel gear 46 meshing with it is driven by the main bevel gear 4501, so that the cleaning shaft 42 located on the lower side of the cleaning box 41 rotates, thereby driving the cleaning shaft 42 located on the upper side of the cleaning box 41 to rotate through the cooperation of the upper and lower spur gears 4202, and the charging cable 1105 that is about to enter the storage chamber 12 will be straightened in advance by the guide roller 8, so as to facilitate the subsequent cleaning and storage. After the external charging cable 1105 passes through the guide roller 8, it will enter the cleaning box 41 from the cable channel 4101, and then the dust and other debris on the charging cable 1105 will be cleaned by the cleaning brush 4201 on the upper and lower rotating cleaning shafts 42 in the cleaning chamber 4102. When brushing, part of the dust and other debris brushed away will fall into the collecting box 47 at the bottom of the cleaning chamber 4102 and be collected. At the same time, the cleaning chamber 4102 can also effectively prevent the dust and other debris brushed off from entering other places. After the charging cable 1105 is brushed and cleaned by the cleaning brush 4201, some loose dust and other debris will still remain on the surface of the charging cable 1105. The charging cable 1105 continues to pass through the rotating shaft 43 provided with the cleaning cotton 4301. The rotating shaft 43 uses the friction between the cleaning cotton 4301 and the charging cable 1105 to make the cleaning cotton 4301 wipe the charging cable 1105, and completely wipe off the dust and other debris remaining on the surface of the charging cable 1105. When there is water on the charging cable 1105, the cleaning cotton 4301 can wipe the charging cable 1105 dry to prevent the charging cable 1105 from bringing water into the charging pile and causing hidden dangers.

Furthermore, a storage box 1103 is installed in the main engine room 11, and the storage box 1103 is used to store coolant and adjust the temperature of the coolant. A liquid cooling pipe 1104 is coiled inside the charging module 1101, and the liquid cooling pipe 1104 extends to the outside of the charging module 1101 and is connected to the storage box 1103. A circulating pump 1102 is arranged on the liquid cooling pipe 1104.

In the process of charging by the charging pile, the circulating pump 1102 in the main engine room 11 is started, and the cooling liquid in the storage tank 1103 is transported into the radiator on the charging module 1101 through one end of the liquid cooling pipe 1104, and the cooling liquid returns to the storage tank 1103 through the other end of the liquid cooling pipe 1104, and the cycle is repeated. In the process of continuous circulation of the cooling liquid, the cooling liquid effectively takes away a large amount of heat generated inside the charging module 1101, and dissipates the heat of the charging module 1101.

Furthermore, a conical protrusion 21 with a tip pointing toward the storage chamber 12 is provided on the charging cable 1105, and the protrusion 21 is close to the tail end of the charging gun 2. A fixing rod 6 and a support frame 7 are provided in the storage chamber 12, and the fixing rod 6 is located directly above the support frame 7. A fixing seat 71 is provided between the fixing rod 6 and the support frame 7, and a supporting spring 72 is fixedly connected between the lower side of the fixing seat 71 and the upper side of the support frame 7. Guide rollers 8 are rotatably installed on the fixing rod 6 and the fixing seat 71, and the charging cable 1105 passing through the cleaning box 41 passes between the two guide rollers 8. A pressure sensor 73 is provided on one side of the support frame 7, and the pressure sensor 73 is connected to the storage motor 31 through an electrical signal. A pressure rod 74 is fixedly connected to one side of the fixing seat 71, and the pressure rod 74 corresponds to the position of the pressure sensor 73.

Among them, the guide roller 8 straightens the charging cable 1105 before it enters the cleaning box 41 to facilitate the entry of the charging cable 1105. When the charging cable 1105 is twisted, tightened and gradually tilted, the charging cable 1105 twisted and tightened due to the torsion will press the guide roller 8 below it downward, so that the guide roller 8 below it gradually presses toward the support frame 7 with the fixed seat 71. During this process, the support spring 72 between the fixed seat 71 and the support frame 7 will be compressed, and the fixed seat 71 will press the pressure sensor 73 with the pressure rod 74, so that the pressure sensor 73 is triggered to send a signal to the storage motor 31, and then the storage motor 31 stops rotating, and the storage mechanism 3 suspends storage to prevent the torsion on the charging cable 1105 from exceeding its tolerable limit and causing damage. After the torsion is removed, the charging cable 1105 is 05 is no longer twisted and tense and becomes soft, ending the pressure on the guide roller 8 below it, causing the fixed seat 71 to lose the pressure on the support spring 72, so that the support spring 72 props up the fixed seat 71 and resets it. At the same time, the pressure rod 74 will also leave the pressure sensor 73, causing the pressure sensor 73 to send a signal to the storage motor 31 again, and the paused storage motor 31 continues to work, so that the storage mechanism 3 can store the remaining charging cable 1105. As the charging cable 1105 continues to be stored, when the protrusion 21 gradually enters between the two guide rollers 8, the support spring 72 between the fixed seat 71 and the support frame 7 will be compressed, and the fixed seat 71 will press against the pressure sensor 73 with the pressure rod 74, so that the pressure sensor 73 is triggered and sends a signal to the storage motor 31, and then the storage motor 31 stops and ends the storage.

Furthermore, a box taking-out opening 13 is opened on one side of the storage chamber 12, and the box taking-out opening 13 corresponds to the position of the collection box 47. A baffle 1301 is slidably fitted on the outer side of the box taking-out opening 13, and the baffle 1301 can slide up and down on the box taking-out opening 13 to control the opening and closing of the box taking-out opening 13.

When the collection box 47 is full, the baffle 1301 can be lifted upward to open the box taking-out opening 13 and remove the collection box 47 for processing. After processing the collection box 47, the collection box 47 is installed back and the baffle 1301 is pushed to close the box taking-out opening 13.

Working principle: When in use, first remove the charging gun 2 from the charging gun storage rack 1201, then the storage motor 31 rotates in the opposite direction, and drives the transmission gear 34 meshed with it through the driving gear 35, so that the transmission gear 34 drives the turntable 3201 to rotate clockwise, and the rotating turntable 3201 drives the winding rod 3202 and the take-up clamp 33 to rotate clockwise around the take-up roller 32. During this process, the limit rod 3301 on the take-up clamp 33 will slide along the spiral direction of the spiral groove 3203, driving the take-up clamp 33 to slide upward on the winding rod 3202, allowing the take-up roller 32 to rotate clockwise. The wire clamp 33 releases the charging cable 1105 from the take-up roller 32 along the spiral direction of the charging cable 1105 from bottom to top. At the same time, the released charging cable 1105 is pulled out from the storage chamber 12 through the charging gun 2. After the appropriate length is pulled out, the storage motor 31 is turned off to stop the release of the charging cable 1105. Then the charging gun 2 is docked with the electric vehicle to be charged. After the charging gun 2 is docked, the charging pile charges it. At the same time, the circulating pump 1102 in the main engine room 11 is started, which transports the coolant in the storage box 1103 through one end of the liquid cooling pipe 1104. The coolant is sent into the radiator on the charging module 1101, and the coolant passes through the other end of the liquid cooling pipe 1104 to circulate. During the continuous circulation of the coolant, the coolant effectively takes away a large amount of heat generated inside the charging module 1101, and dissipates the heat of the charging module 1101 and the charging cable. After the electric vehicle is charged, the charging gun 2 is removed from the electric vehicle, and then the charging gun 2 is inserted back into the charging gun storage rack 1201. Then, the storage mechanism 3 in the storage chamber 12 begins to store the drawn charging cable 1105. The storage mechanism 3 in the storage chamber 12 The nanomotor 31 starts forward, and drives the transmission gear 34 meshing with it through the driving gear 35, so that the transmission gear 34 drives the turntable 3201 to rotate counterclockwise, and the rotating turntable 3201 drives the winding rod 3202 and the take-up clamp 33 to rotate counterclockwise around the take-up roller 32. During this process, the limit rod 3301 on the take-up clamp 33 will slide along the spiral direction of the spiral groove 3203, driving the take-up clamp 33 to slide downward on the winding rod 3202, so that the take-up clamp 33 winds the charging cable 1105 from top to bottom along the spiral direction of the charging cable 1105 onto the take-up roller 32;

During the process of the charging cable 1105 being retracted, the transmission motor 45 under the cleaning box 41 is started, so that the cleaning mechanism 4 can work together with the storage mechanism 3, and the main bevel gear 4501 on the output shaft of the transmission motor 45 drives the secondary bevel gear 46 meshing with it to rotate the cleaning shaft 42 located at the lower side of the cleaning box 41, thereby driving the cleaning shaft 42 located at the upper side of the cleaning box 41 to rotate through the cooperation of the upper and lower spur gears 4202. Before entering the storage chamber 12, the charging cable 1105 will be straightened in advance by the guide roller 8, so as to facilitate the subsequent cleaning and storage. After the external charging cable 1105 passes through the guide roller 8, it will enter the cleaning box 41 from the cable channel 4101, and then the dust and other debris on the charging cable 1105 will be brushed by the cleaning brush 4201 on the upper and lower rotating cleaning shafts 42 in the cleaning chamber 4102. Part of the dust and other debris will fall into the collection box 47 at the bottom of the cleaning chamber 4102 and be collected. At the same time, the cleaning chamber 4102 can also effectively prevent the dust and other debris that are brushed off from entering other places. After the charging cable 1105 is brushed and cleaned by the cleaning brush 4201, some loose dust and other debris will still remain on the surface of the charging cable 1105. The charging cable 1105 continues to pass through the rotating shaft 43 provided with the cleaning cotton 4301. The rotating shaft 43 uses the friction between the cleaning cotton 4301 and the charging cable 1105 to make the cleaning cotton 4301 wipe the charging cable 1105, and completely wipe off the dust and other debris remaining on the surface of the charging cable 1105. When there is water on the charging cable 1105, the cleaning cotton 4301 can dry the charging cable 1105 to prevent the charging cable 1105 from bringing water into the charging pile and causing hidden dangers;

When the take-up clamp of the winding rod 3202 winds the charging cable 1105 around the recycling wire roller 32, torque is generated and concentrated on the charging cable 1105 at the tail end of the charging gun 2 outside the storage chamber 12. As the take-up roller 32 reels more charging cables 1105, the torque on the charging cable 1105 at the tail end of the charging gun 2 becomes greater. When the torque reaches a certain strength, the charging cable 1105 that has not been stored is gradually twisted and tightened due to the torque. At this time, the charging cable 1105 is 5 is not fully retracted, and the charging cable 1105 is wound on the take-up roller 32 from top to bottom, so the position of the charging cable 1105 in the storage chamber 12 is higher than that of the charging cable 1105 outside the storage chamber 12, so that a straight line inclined from the storage chamber 12 to the outside of the storage chamber 12 is gradually formed under continuous storage. At this time, the tight charging cable 1105 in the cleaning box 41 will push up the cleaning shaft 42 and the rotating shaft 43 located above it due to the inclination, so that the cleaning shaft 42 and the rotating shaft 43 push the bearing seat 44 upward, so that the disengagement spring 4401 between the bearing seat 44 and the cleaning box 41 is compressed, and at the same time, the cleaning shaft 42 located on the upper side of the cleaning box 41 will bring the spur gear 4202 thereon to disengage from the spur gear 4202 on the lower cleaning shaft 42, so that the charging cable 1105 twisted and tightened due to the torsion will no longer be cleaned by the cleaning mechanism 4. At the same time, the charging cable 1105 twisted and tightened due to the torsion outside the cleaning box will press the guide roller 8 below it downward, so that the guide roller 8 below it will bring the fixed seat 71 to press toward the support frame 7. In this process, the support spring 72 between the fixed seat 71 and the support frame 7 will be compressed, and the fixed seat 71 will bring the pressure rod 74 to press against the pressure sensor 73, so that the pressure sensor 73 is triggered to send a signal to the storage motor 31, and then the storage motor 31 stops rotating, and the storage mechanism 3 stops storing, so as to prevent the torsion on the charging cable 1105 from exceeding its tolerable limit and causing damage;

The charging cable 1105 at the tail end of the charging gun 2 is twisted and tightened, thereby generating tension, which gradually pulls the fixing part 53 out of the sleeve 51 through the charging gun 2, so that the block 5301 on the fixing part 53 is gradually separated from the slot 5101. At the same time, as the fixing part 53 is stretched, the unloading spring 54 fixedly connected to the fixing part 53 and the unloading shaft 52 will be stretched by the fixing part 53. When the storage motor 31 is paused, the block 5301 is completely separated from the slot 5101. Without the restriction of the block 5301 and the slot 5101, the torsion The bent and taut charging cable 1105 applies a torque to the fixing part 53 through the charging gun 2 to make it rotate. The fixing part 53 drives the unloading shaft 52 to rotate in the sleeve 51 through the guide rod 5201 to remove the torque. After the torque is removed, the charging cable 1105 is relaxed and restored to a natural state, and is no longer twisted and taut, so that the fixing part 53 loses the tension and torque, so that the unloading spring 54 pulls the fixing part 53 back into the sleeve 51, and makes the block 5301 on the fixing part 53 re-engage with the slot 5101, so that the charging gun 2 is fixed again;

At the same time, with the removal of the torque, the charging cable 1105 is no longer twisted and tightened to lift the cleaning shaft 42 and the rotating shaft 43, so that the bearing seat 44 loses the upward thrust on the disengagement spring 4401, and the compressed disengagement spring 4401 of the bearing seat 44 pushes downward, thereby resetting the cleaning shaft 42 and the rotating shaft 43 on the bearing seat 44, and the cleaning shaft 42 located on the upper side of the cleaning box 41 will bring the spur gear 4202 thereon to re-engage with the spur gear 4202 on the lower cleaning shaft 42, at the same time, the fixed seat 71 also loses the pressure on the supporting spring 72, so that the supporting spring 72 props up the fixed seat 71 to reset, and at the same time, the pressure rod 74 will also leave the pressure sensor 73, so that the pressure sensor 73 sends a signal to the storage motor 31 again, and the suspended storage motor 31 continues to work, so that the storage mechanism 3 will remove the remaining charging cable 1105 is stored. As the charging cable 1105 continues to be stored, the protrusion 21 thereon will gradually enter between the two guide rollers 8 and press the guide roller 8 below it downward, so that the guide roller 8 below it is pressed toward the support frame 7 with the fixed seat 71. At the same time, the support spring 72 between the fixed seat 71 and the support frame 7 will be compressed, and the fixed seat 71 will press the pressure sensor 73 with the pressure rod 74, so that the pressure sensor 73 is triggered and sends a signal to the storage motor 31. Then the storage motor 31 stops to end the storage, and the transmission motor 45 is turned off to end the cleaning. When the collection box 47 is filled, the baffle 1301 can be lifted up to open the box removal port 13 to remove the collection box 47 for processing. After processing the collection box 47, the collection box 47 is installed back and the baffle 1301 is pushed to close the box removal port 13.
