Description

Technical Field

[0001] The invention belongs to the field of charging piles, in particular to a gun insertion mechanism of a charging pile. Background Art

[0002] A charging pile refers to a charging device that provides energy for electric vehicles. It can be fixed on the ground or wall and installed in parking lots or charging stations in public buildings and residential communities. The input end of the charging pile is directly connected to the AC power grid, and the output end is equipped with a charging gun for charging electric vehicles.

[0003] The gun insertion mechanism of the charging pile is used to place the charging gun. After charging is completed, the user needs to put the charging gun into the gun insertion mechanism to end the charging. It not only protects the charging gun, but also serves as a time standard for charging.

[0004] The traditional gun plug-in mechanism is generally exposed on the outside of the charging pile, so that the charging gun is also exposed. This setting is to facilitate pedestrians and vehicles to easily see that there is a charging pile here. However, this not only makes the charging gun susceptible to the influence of natural weather such as wind and sun, resulting in a reduced service life, but there are also many people in the society who do not know how to use the charging gun correctly, or some deliberately bad people. When plugging and unplugging the charging gun, they do not unlock it properly and forcibly pull the charging gun out, which will cause damage to the entire gun plug-in mechanism or the charging gun, causing greater losses.

[0005] To this end, the present invention provides a gun insertion mechanism for a charging pile. Summary of the invention

[0006] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0007] The technical solution adopted by the present invention to solve the technical problem is as follows: the gun insertion mechanism of a charging pile described in the present invention comprises a spliced ​​shell, an elliptical gun-taking hole is provided on one side of the middle part of the spliced ​​shell, a separation seat is provided on the inner wall of the gun-taking hole, a gun insertion row is provided on the side of the separation seat facing the gun-taking hole, a hole for inserting a charging gun is provided at the front end of the gun insertion row, the gun insertion row penetrates to the inner side of the separation seat, a driving component is provided inside the separation seat, and the driving component is used to drive the separation seat to rotate;

[0008] Through the setting of the spliced ​​shell and the structure of the spliced ​​shell and the gun removal hole, after regular electronic unlocking, the drive assembly will drive the separation seat to rotate outward, and at the same time the gun insertion row will be unlocked, so that the charging gun inserted in the gun insertion row can be easily pulled out. If the regular electronic unlocking is not performed, the separation seat cannot rotate. At the same time, because the gun insertion row is facing the gun removal hole, the space in the gun removal hole is small, and the human arm strength cannot act on the charging gun correctly, which will reduce the damage caused by hard pulling out the charging gun. At the same time, with this setting, the charging gun is still exposed to the outside, allowing passers-by to easily observe the charging gun, and can also provide a certain amount of protection for the charging gun.

[0009] Preferably, the driving assembly includes a servo motor, the output end of the servo motor is vertically downward and fixedly connected to a transmission rod, the middle part of the transmission rod is fixedly connected to a positioning plate adapted to the gun row, and the side of the positioning plate facing the gun row is fixedly connected to a docking seat, and the transmission rod is driven to rotate by the servo motor, thereby driving the entire separation seat to rotate outward forty-five degrees, so that it is more convenient to pull out or insert the charging gun. When the charging gun is inserted deep into the gun row, it will be completely combined with the docking seat on the positioning plate to form a fixation, and then the servo motor drives the separation seat to rotate back to its position.

[0010] Preferably, an annular groove is provided in the hole of the plug gun row, the annular groove is close to the insertion end of the plug gun row, an expansion ring is provided in the annular groove, the expansion ring is made of elastic material, an air pump is provided on the inner side of the plug gun row, a plurality of air intake valves are provided on the outer side of the expansion ring, the plurality of air intake valves are connected to the air pump, a power assembly is provided on the inner side of the expansion ring, the power assembly is used to send the charging gun into the plug gun row, when the traditional plug gun mechanism is docked with the charging gun, the user is required to fully insert the charging gun and complete the locking, but because the user's usage specifications are not standard, it is easy for the internal structure of the plug gun row to gradually wear out after repeated use, and later it is often difficult for the charging gun to return to its original position, making it impossible for the user to return the charging gun. The problem is that through the setting of the expansion ring, the inner diameter of the hole of the plug gun row is larger than the outer diameter of the charging gun, which allows the head of the charging gun to be easily inserted into the plug gun row. A laser sensing module is provided at the end of the plug gun row. When the charging gun is inserted, the air pump will be controlled to fill the expansion ring with air pressure. The expanded expansion ring will grab the end of the charging gun, and the user can release his hand at this time. Under the action of the power component in the expansion ring, the charging gun can be inserted inward and docked with the docking seat. After it is fully returned to its original position, the separation seat will rotate back to its original position. Through this setting, the entire docking and returning process is mechanically controlled, and the docking force and angle are predetermined, which will not damage subsequent parts, greatly reducing the problem of parts damage caused by irregular operations in the manual docking process.

[0011] Preferably, the power assembly includes a plurality of protruding capsules, the protruding capsules are connected to the expansion ring, and one side of the protruding capsules is in contact with the inner wall of the annular groove, an eccentric rod is arranged in the protruding capsule, one end of the eccentric rod is connected to a semicircular ball, a reduction motor is connected to the circular surface of the semicircular ball, the reduction motor is fixedly connected to the gun row, the eccentric rod is eccentrically connected to the arc surface of the semicircular ball, the reduction motor is inclined, after the expansion ring is expanded, the plurality of reduction motors are started to drive the semicircular ball to rotate, because the eccentric rod and the semicircular ball are eccentrically connected, when the semicircular ball rotates, the shape formed by the rotation of the eccentric rod is The cone shape, plus the entire reduction motor is tilted, so the cone formed by the rotation of the eccentric rod is also tilted, which allows the end of the eccentric rod to squeeze the protruding capsule when it rotates to the bottom. As multiple reduction motors are started together, the electric gun head clamped in the middle can be stably transported inward. The reason why the power component is designed like this is that, first, the structure is simple and errors are reduced. Second, the protruding capsule will expand outward, and placing parts in the protruding capsule will easily cause position changes. This design not only can stabilize the drive, but also the eccentric rod will not change position due to the expansion of the protruding capsule, thereby ensuring the normal driving process.

[0012] Preferably, a hanging plate is provided below the gun insertion row, the hanging plate is fixedly connected to the separation seat, a slot is provided on the top surface of the hanging plate, two symmetrically arranged force-bearing rods are rotatably connected to the slot wall, one end of the force-bearing rod is connected to a power module and a pressure detection module, when the charging gun is fixed in place, the gun body will fit with the hanging plate, the slot provided on the hanging plate will clamp the gun body, and at the same time, the two force-bearing rods will rotate outwards driven by the power module and surround the outside of the gun body, thereby further fixing the charging gun, and a sound alarm module is provided on the outside of the separation seat, when someone forcibly pulls out the gun, the gun body will be subjected to force first, which will cause the pressure detection module on the force-bearing rod to detect it, thereby triggering the sound alarm module to warn the person who forcibly pulls out the gun.

[0013] Preferably, blocking rods are provided on both sides of the splicing shell, and a cross bar is fixed between the bottoms of the two blocking rods. A movable groove extending to the rear end is provided at the front end of the splicing shell, and the top of the blocking rod is rotatably connected to the outer side of the splicing shell. A translation assembly is provided on the inner side of the splicing shell, and the translation assembly is used to drive the cross bar to translate. Through the setting of the blocking rod, after the charging pile is normally unlocked, the blocking rod will move to a vertical state driven by the translation assembly, so that the entire charging gun is not blocked. When it is not unlocked, the blocking rod is horizontally located on the outside of the gun removal hole, so that it is difficult for outsiders to directly touch the charging gun, further reducing the damage to the charging gun and the gun insertion structure, and the entire blocking rod has a simple structure and is not afraid of damage, and at the same time it will not block the view of the charging gun.

[0014] Preferably, the translation assembly includes a flexible transmission belt, an electric shaft and two positioning rods are provided on the inner side of the spliced ​​shell, the transmission belt is arranged in a ring shape, a sleeve is sleeved on the outer side of the cross bar, the transmission belt is fixedly connected to the outer side of the sleeve, the annular transmission belt is sleeved on the outer sides of the two positioning rods and the electric shaft, the movable groove is arranged in an arc shape, and the transmission belt is driven to move by the electric shaft. Since the transmission belt is made of flexible material and the sleeve and the cross bar are rotatably connected, the sleeve can be driven to move in an arc, thereby achieving the blocking and unblocking effects of the blocking rod.

[0015] Preferably, a winding roller is rotatably connected to the inner side of the spliced ​​shell, one end of the winding roller is connected to a driving motor, and the other end of the winding roller is connected to the power supply of the charging pile.

After the charging cable is combined with the gun row, the winding roller is reeled up to recycle the cable, so that the length of the cable can adapt to the user, thereby improving the convenience of use.

[0016] Preferably, the cross-sectional area of ​​the end of the docking seat close to the gun row is smaller than that of the end close to the positioning plate. An electric buckle is provided at the end of the docking seat. During the docking process between the charging gun and the docking seat, the muzzle will slowly align with the docking seat, cooperating with the setting of the docking seat that is wide in front and narrow in the back, to assist the charging gun in correcting its position, and finally the electric buckle is used to lock it to complete the fixation.

[0017] Preferably, a wireless ranging module is provided inside the charging gun row, and the wireless ranging module is communicatively connected with the driving motor of the winding roller. In cooperation with the ranging function of the wireless ranging module, as the charging gun is taken away, the winding roller will release an appropriate amount of cable according to the distance, and as the charging gun is approached, the winding roller will appropriately reel in the cable to ensure that the length of the cable leaking out to the outside is appropriate.

[0020] 2. The gun insertion mechanism of a charging pile described in the present invention drives the transmission rod to rotate through the servo motor, thereby driving the entire separation seat to rotate outward by 45 degrees, so that it is more convenient to pull out or insert the charging gun.

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] like Figures 1 to 3 As shown, a gun insertion mechanism of a charging pile according to an embodiment of the present invention comprises a splicing shell 1, an elliptical gun taking hole 2 is provided at one side of the middle of the splicing shell 1, a separation seat 3 is provided on the inner wall of the gun taking hole 2, a gun insertion row 4 is provided on the side of the separation seat 3 facing the gun taking hole 2, a hole for inserting a charging gun is provided at the front end of the gun insertion row 4, the gun insertion row 4 penetrates to the inner side of the separation seat 3, a driving component is provided inside the separation seat 3, and the driving component is used to drive the separation seat 3 to rotate;

[0032] When working, the traditional gun insertion mechanism is generally exposed on the outside of the charging pile, so that the charging gun is also exposed to the outside. This setting is to facilitate pedestrians and vehicles to easily see that there is a charging pile here. However, this not only makes the charging gun easily affected by natural weather such as wind and sun, resulting in a reduced service life, but also there are many people in the society who do not know how to use the charging gun correctly, or some deliberately bad people, when plugging and unplugging the charging gun, they do not unlock it properly, and just pull the charging gun outward, which will cause the entire gun insertion mechanism to be damaged, or the charging gun to be damaged, causing greater losses, through the setting of the splicing shell 1;

[0033] By splicing the shell 1 and the gun access hole 2, after regular electronic unlocking, the driving assembly will drive the separation seat 3 to rotate outward, and the gun insertion row 4 will be unlocked, so that the charging gun inserted in the gun insertion row 4 can be easily pulled out. If regular electronic unlocking is not performed, the separation seat 3 cannot rotate. At the same time, since the gun insertion row 4 is facing the gun access hole 2, the space in the gun access hole 2 is small, and the human arm strength cannot act on the charging gun correctly, which will reduce the damage caused by hard pulling out the charging gun. At the same time, with this setting, the charging gun is still exposed to the outside, so that passers-by can easily observe the charging gun, and the charging gun can also be protected to a certain extent.

[0034] like Figures 1 to 5 As shown, the driving assembly includes a servo motor 9, the output end of the servo motor 9 is vertically downward and fixedly connected to a transmission rod 13, the middle of the transmission rod 13 is fixedly connected to a positioning plate 14 adapted to the gun insertion row 4, and the positioning plate 14 is fixedly connected to a docking seat 16 on one side facing the gun insertion row 4;

[0035] During operation, the transmission rod 13 is driven to rotate by the servo motor 9, thereby driving the entire separation seat 3 to rotate outward forty-five degrees, so that it is more convenient to pull out or insert the charging gun. When the charging gun is inserted deep into the gun row 4, it will be completely combined with the docking seat 16 on the positioning plate 14 to form a fixed position, and then the servo motor 9 drives the separation seat 3 to rotate back to its original position.

[0036] like Figures 1 to 5 As shown, an annular groove is provided in the hole of the plug-in gun row 4, the annular groove is close to the insertion end of the plug-in gun row 4, an expansion ring 17 is provided in the annular groove, the expansion ring 17 is made of elastic material, an air pump is provided on the inner side of the plug-in gun row 4, a plurality of air intake valves are provided on the outer side of the expansion ring 17, and the plurality of air intake valves are connected to the air pump, a power assembly is provided on the inner side of the expansion ring 17, and the power assembly is used to send the charging gun into the plug-in gun row 4;

[0037] During operation, when the traditional plug-in mechanism is docked with the charging gun, the user is required to fully insert the charging gun and complete the locking. However, due to the non-standard usage specifications of the users, after repeated use, the internal structure of the plug-in gun row 4 is easily worn out. In the later stage, it is often difficult for the charging gun to return to its original position correctly, making it impossible for the user to return the charging gun. Through the setting of the expansion ring 17, the inner diameter of the hole of the plug-in gun row 4 is larger than the outer diameter of the charging gun, so that the head of the charging gun can be easily inserted into the plug-in gun row 4. A laser sensing module is provided at the end of the plug-in gun row 4. When the charging gun is inserted, the air pump will be controlled to fill the expansion ring 17 with air pressure. The expanded expansion ring 17 will grab the end of the charging gun. At this time, the user can release his hand. Under the action of the power component in the expansion ring 17, the charging gun can be inserted inward and docked with the docking seat 16. After fully returning to its original position, the separation seat 3 is rotated back to its original position. Through this setting, the entire docking and returning process is mechanically controlled, and the docking force and angle are predetermined, which will not damage subsequent parts, greatly reducing the problem of part damage caused by irregular operations during manual docking.

[0038] like Figure 5 to Figure 6 As shown, the power assembly includes a plurality of protruding capsules 18, the protruding capsules 18 are connected to the expansion ring 17, and one side of the protruding capsules 18 is in contact with the inner wall of the annular groove, an eccentric rod 20 is arranged in the protruding capsule 18, one end of the eccentric rod 20 is connected to a semicircular ball 19, a reduction motor 21 is connected to the circular surface of the semicircular ball 19, the reduction motor 21 is fixedly connected to the insertion gun row 4, the eccentric rod 20 is eccentrically connected to the arc surface of the semicircular ball 19, and the reduction motor 21 is arranged obliquely;

[0039] During operation, after the expansion ring 17 expands, multiple reduction motors 21 are started to drive the semi-circular sphere 19 to rotate. Since the eccentric rod 20 and the semi-circular sphere 19 are eccentrically connected, when the semi-circular sphere 19 rotates, the shape formed by the rotation of the eccentric rod 20 is a cone. In addition, the entire reduction motor 21 is tilted, so the cone formed by the rotation of the eccentric rod 20 is also tilted. This allows the end of the eccentric rod 20 to squeeze the protruding capsule 18 when it rotates to the bottom. As multiple reduction motors 21 are started together, the electric gun head clamped in the middle can be stably transported inward. The reason why the power component is designed like this is that, first, the structure is simple and errors are reduced. Second, the protruding capsule 18 will expand outward, and placing parts in the protruding capsule 18 is prone to position changes. This design can not only stably drive, but also the eccentric rod 20 will not change position due to the expansion of the protruding capsule 18, thereby ensuring the normal driving process.

[0040] like Figures 1 to 5 As shown, a hanging plate 5 is arranged below the gun insertion row 4, the hanging plate 5 is fixedly connected to the separation seat 3, a card slot is opened on the top surface of the hanging plate 5, two symmetrically arranged force rods 15 are rotatably connected to the card slot wall, and one end of the force rod 15 is connected to the power module and the pressure detection module;

[0041] During operation, after the charging gun is fixed in place, the gun body will fit with the hanging plate 5, and the card slots on the hanging plate 5 will clamp the gun body. At the same time, the two force-bearing rods 15 will rotate outwards under the drive of the power module and surround the outside of the gun body, thereby further fixing the charging gun. A sound alarm module is provided on the outside of the separation seat 3. When someone forcibly pulls out the gun, the gun body will be stressed first, causing the pressure detection module on the force-bearing rod 15 to detect it, thereby triggering the sound alarm module to warn the person who forcibly pulls out the gun.

[0042] like Figures 1 to 5 As shown, blocking rods 8 are provided on both sides of the splicing shell 1, a cross bar is fixedly connected between the bottoms of the two blocking rods 8, a moving groove 7 is provided at the front end of the splicing shell 1 and extends to the rear end, the top end of the blocking rod 8 is rotatably connected to the outer side of the splicing shell 1, and a translation assembly is provided on the inner side of the splicing shell 1, and the translation assembly is used to drive the cross bar to translate;

[0043] During operation, through the setting of the blocking rod 8, after the charging pile is unlocked normally, the blocking rod 8 will move to a vertical state driven by the translation assembly, so that the entire charging gun is not blocked. When it is not unlocked, the blocking rod 8 is horizontally placed on the outside of the gun taking hole 2, so that it is difficult for outsiders to directly touch the charging gun, further reducing the damage to the charging gun and the gun insertion structure. The entire blocking rod 8 has a simple structure and is not afraid of damage, and it will not block the view of the charging gun.

[0044] like Figures 1 to 5As shown, the translation assembly includes a flexible transmission belt 12, an electric shaft 11 and two positioning rods are arranged on the inner side of the spliced ​​housing 1, the transmission belt 12 is arranged in an annular shape, a sleeve is sleeved on the outer side of the cross bar, the transmission belt 12 is fixedly connected to the outer side of the sleeve, the annular transmission belt 12 is sleeved on the outer side of the two positioning rods and the electric shaft 11, and the moving groove 7 is arranged in an arc shape;

[0045] During operation, the transmission belt 12 is driven to move by the electric shaft 11. Since the transmission belt 12 is made of flexible material and the sleeve and the cross bar are rotatably connected, the sleeve can be driven to move in an arc, thereby achieving the blocking and unblocking effects of the blocking rod 8.

[0046] like Figures 1 to 5 As shown, a winding roller 10 is rotatably connected to the inner side of the splicing shell 1, one end of the winding roller 10 is connected to a driving motor, and the other end of the winding roller 10 is connected to the power supply of the charging pile, and an outlet pipe 6 is fixedly connected to the inner wall of the gun-taking hole 2;

[0047] During operation, the charging gun is taken out and pulled outward, and the winding roller 10 will rotate appropriately to spit out the cable. After the charging cable is combined with the plug gun row 4, the winding roller 10 is reeled in to recycle the cable, so that the length of the cable can adapt to the user, thereby improving the convenience of use.

[0048] like Figures 1 to 5 As shown, the cross-sectional area of ​​the end of the docking seat 16 close to the gun row 4 is smaller than that of the end close to the positioning plate 14. An electric buckle is provided at the end of the docking seat 16. When working, during the docking process between the charging gun and the docking seat 16, the muzzle will slowly align with the docking seat 16, and cooperate with the setting of the docking seat 16 that is wide in front and narrow in the back to assist the charging gun to correct its position, and finally use the electric buckle to lock it to complete the fixation.

[0049] like Figures 1 to 5 As shown, a wireless distance measuring module is provided inside the charging gun row 4, and the wireless distance measuring module is communicated with the driving motor of the winding roller 10. When working, in conjunction with the distance measuring function of the wireless distance measuring module, as the charging gun is taken away, the winding roller 10 will release an appropriate amount of cable according to the distance, and as the charging gun approaches, the winding roller 10 will appropriately reel in the cable to ensure that the length of the cable leaking out to the outside is appropriate.

[0050] During operation, through the structure of splicing the shell 1 and the gun-taking hole 2, after regular electronic unlocking, the driving component will drive the separation seat 3 to rotate outward, and at the same time the gun-insertion row 4 will be unlocked, so that the charging gun inserted in the gun-insertion row 4 can be easily pulled out. If the regular electronic unlocking is not performed, the separation seat 3 cannot rotate. At the same time, because the gun-insertion row 4 faces the gun-taking hole 2, the space in the gun-taking hole 2 is small, and the human arm strength cannot act on the charging gun correctly, which will reduce the damage caused by hard pulling of the charging gun. At the same time, with this setting, the charging gun is still exposed to the outside, so that passers-by can easily observe the charging gun, and the charging gun can also be protected to a certain extent.

[0051] The servo motor 9 drives the transmission rod 13 to rotate, thereby driving the entire separation seat 3 to rotate outward by 45 degrees, so that it is more convenient to pull out or insert the charging gun. When the charging gun is inserted deep into the plug-in row 4, it will be completely combined with the docking seat 16 on the positioning plate 14 to form a fixation, and then the servo motor 9 drives the separation seat 3 to rotate back to its original position;

[0052] When the traditional plug-in mechanism is docked with the charging gun, the user needs to fully insert the charging gun and complete the locking. However, due to the non-standard usage specifications of the users, after multiple uses, the internal structure of the plug-in gun row 4 is easily worn out. In the later stage, the charging gun is often difficult to return to its original position correctly, making it impossible for the user to return the charging gun. Through the setting of the expansion ring 17, the inner diameter of the hole of the plug-in gun row 4 is larger than the outer diameter of the charging gun, so that the head of the charging gun can be easily inserted into the plug-in gun row 4. A laser sensing module is provided at the end of the plug-in gun row 4. When the charging gun is inserted, the air pump will be controlled to fill the expansion ring 17 with air pressure. The expanded expansion ring 17 will grab the end of the charging gun. At this time, the user can let go. Under the action of the power component in the expansion ring 17, the charging gun can be inserted inward and docked with the docking seat 16. After fully returning to its original position, the separation seat 3 is rotated back to its original position. Through this setting, the entire docking and returning process is mechanically controlled, and the docking force and angle are predetermined, which will not damage subsequent parts, greatly reducing the problem of part damage caused by irregular operations during manual docking.

[0053] After the expansion ring 17 expands, multiple reduction motors 21 are started to drive the semi-circular ball 19 to rotate. Since the eccentric rod 20 and the semi-circular ball 19 are eccentrically connected, when the semi-circular ball 19 rotates, the shape formed by the rotation of the eccentric rod 20 is a cone. In addition, the entire reduction motor 21 is tilted, so the cone formed by the rotation of the eccentric rod 20 is also tilted, which makes the end of the eccentric rod 20 squeeze the protruding capsule 18 when it rotates to the bottom. With the start of multiple reduction motors 21, the electric gun head clamped in the middle can be stably transported inward. The reason why the power component is designed like this is that, first, the structure is simple and errors are reduced. Second, the protruding capsule 18 will expand outward, and placing parts in the protruding capsule 18 is prone to position changes. This design can not only stably drive, but also the eccentric rod 20 will not change position due to the expansion of the protruding capsule 18, thereby ensuring the normal driving process.

[0054] When the charging gun is fixed in place, the gun body will fit with the hanging plate 5, and the slots on the hanging plate 5 will clamp the gun body. At the same time, the two force-bearing rods 15 will rotate outwards under the drive of the power module and surround the outside of the gun body, thereby further fixing the charging gun. A sound alarm module is arranged on the outside of the separation seat 3. When someone forcibly pulls out the gun, the gun body will be stressed first, causing the pressure detection module on the force-bearing rod 15 to detect it, thereby triggering the sound alarm module to warn the person who forcibly pulls out the gun.

[0055] By setting the blocking rod 8, after the charging pile is normally unlocked, the blocking rod 8 will be moved to a vertical state driven by the translation assembly, so that the entire charging gun is not blocked. When unlocked, the blocking rod 8 is horizontally arranged outside the gun access hole 2, so that it is difficult for outsiders to directly touch the charging gun, further reducing the damage to the charging gun and the gun insertion structure. In addition, the entire blocking rod 8 has a simple structure and is not afraid of damage, and it will not block the view of the charging gun.

[0056] The electric shaft 11 drives the transmission belt 12 to move. Since the transmission belt 12 is made of flexible material and the sleeve and the crossbar are rotatably connected, the sleeve can be driven to move in an arc, thereby achieving the blocking and unblocking effect of the blocking rod 8.

[0057] After the charging gun is taken out and pulled out, the winding roller 10 will rotate appropriately to spit out the cable. After the charging cable is combined with the plug gun row 4, the winding roller 10 reels the cable to recycle it, so that the length of the cable can adapt to the user, thereby improving the convenience of use;

[0058] During the docking process between the charging gun and the docking seat 16, the muzzle will slowly align with the docking seat 16, and cooperate with the setting of the docking seat 16 that is wide in front and narrow in the back to help the charging gun correct its position, and finally use the electric buckle to lock it to complete the fixation;

[0059] In cooperation with the ranging function of the wireless ranging module, as the charging gun is taken away, the winding roller 10 will release an appropriate amount of cable according to the distance. As the charging gun approaches, the winding roller 10 will appropriately reel in the cable to ensure that the length of the cable leaking out to the outside is appropriate.
