[0015] The beneficial effects of the present invention are:

[0016] 1. Compared with the prior art, in the present invention, the walking unit is used to assist the vertical charging pile in adjusting its position, the locking unit can lock the position of the charging gun, and the tensioning unit can wind and tighten the cable to prevent the cable from falling on the ground, thereby protecting the cable itself and avoiding long-term friction between the cable and the ground. Through the setting of the disengagement unit, the cable can be pushed out from the tensioning unit when charging is needed, making it convenient for the user to take the charging gun for charging.

[0017] 2. Compared with the prior art, in the present invention, the second threaded rod rotates, the nut block moves downward, driving the synchronous rod to slide downward, and the synchronous rod pulls the connecting plate and the first limit plate to move downward, and the cable is no longer limited; while the synchronous rod moves downward, the first rack drives the gear to rotate, and the gear drives the second rack to move upward, and the second rack drives the top plate and the second limit plate to move upward, so that the second limit plate no longer limits the cable, so that the cable can be easily taken out, and the arrangement of the first limit plate and the second limit plate makes it convenient to limit the cable.

[0018] 3. Compared with the prior art, in the present invention, when the parking position of the vehicle is not suitable and the length of the cable is not enough for the charging gun to be plugged into the vehicle, the threaded rod can be rotated to drive the base to move, and the base drives the charging pile to move and adjust, which can further bring the charging gun closer to the vehicle for convenient charging.

[0019] 4. Compared with the prior art, in the present invention, after the second limit plate drives the top plate to move upward, the top plate will drive the push plate to move upward, and the push plate will drive the resistance block to move upward. After the resistance block moves upward for a certain distance, it will resist the force-bearing plate. After the force-bearing plate is subjected to force, it will rotate upward, thereby driving the swivel to rotate. After the swivel rotates, it will drive the spiral piece to rotate. Due to the spiral structure of the spiral piece, when the spiral piece rotates, it will squeeze the cable from the outside of the first guide column, thereby realizing the automatic shedding of the cable without manual manipulation, thereby facilitating the detachment of the cable.

[0020] 5. Compared with the prior art, in the present invention, when returning the charging gun, the user needs to wrap the cable around the outside of the first guide column and the second guide column. After the cable is wrapped around the first guide column and the second guide column, the cable will contact the second bevel, allowing the slide plate to drive the contact rod to contact the pressure sensor, so that the pressure sensor transmits the signal to the control module, and the control module controls the cylinder to push the locking rod out to lock the charging gun. If no pressure signal is detected, it is determined that the cable is not wrapped around the outside of the first guide column and the second guide column, and thus it cannot be locked. Therefore, the user must wrap the cable around and store it before returning the charging gun, which further ensures that the cable will not be placed on the ground at will.

The external fixed connection of the side frame 400 is a limiting rod 4004, which penetrates the nut block 4005. The limiting rod 4004 is used to guide the nut block 4005. After the second threaded rod 4003 rotates, it is used to drive the nut block 4005 to perform linear motion adjustment.

[0033] In addition, a first sliding opening 4006 is provided on the outside of the side frame 400, and the first sliding opening 4006 is used to pass the synchronization rod 6008, and the synchronization rod 6008 is fixedly connected to the outside of the nut block 4005, and the first rack 800 is fixedly connected to the outside of the synchronization rod 6008. The side frame 400 is rotatably connected to the outside of the gear 8001, and the second rack 8002 is meshed with the outside of the gear 8001.

[0037] In a further design, a first side cover 6003 and a second side cover 7001 are fixedly connected to the outside of the first guide column 6002 and the second guide column 700 respectively, a support plate 60010 is fixedly connected to the outside of the first side cover 6003 and the second side cover 7001, a first slide groove 6006 is provided on the outside of the first limiting plate 6005, a second slide groove 7003 is provided on the outside of the second limiting plate 7002, a first fixed plate 6009 is fixedly connected in the first slide groove 6006, a second fixed plate 7005 is fixedly connected in the second slide groove 7003, and the first fixed plate 6009 is fixedly connected in the first slide groove 6006. The outside of the fixed plate 6009 is connected to the first spring 6004, and the outside of the second fixed plate 7005 is fixedly connected to the second plate. The first spring 6004 and the second spring 7004 are respectively fixedly connected to the corresponding support plate 60010.

In addition, in order to protect the first rack 800 and the second rack 8002, a protective cover 4001 is fixedly connected to the outside of the side frame 400. A second sliding opening 4009 is provided on the outside of the protective cover 4001, and the synchronization rod 6008 passes through the second sliding opening 4009.

[0038] The above technical solution is explained as follows: the second threaded rod 4003 is driven to rotate by the motor 4002, and the second threaded rod 4003 drives the nut block 4005 to move downward. After the nut block 4005 moves downward, it drives the synchronization rod 6008 to slide downward, and the synchronization rod 6008 pulls the connecting plate 6007 and the first limit plate 6005 to move downward, so that the first limit plate 6005 is retracted into the first guide column 6002, and the first limit plate 6005 no longer limits the cable 1002; the synchronization rod 6008 moves downward At the same time, the first rack 800 drives the gear 8001 to rotate, and the gear 8001 drives the second rack 8002 to move upward, and the second rack 8002 drives the top plate 8003 and the second limiting plate 7002 to move upward, so that the second limiting plate 7002 no longer limits the cable 1002, so that the cable 1002 can be removed, and the setting of the first limiting plate 6005 and the second limiting plate 7002 makes it convenient for the cable 1002 to be entangled by the first guide column 6002 and the second guide column 700, so that it will not fall off.

[0039] The specific usage method of this embodiment is as follows:

[0040] When the user starts charging, the motor 4002 drives the second threaded rod 4003 to rotate, and the second threaded rod 4003 drives the nut block 4005 to move downward. After the nut block 4005 moves downward, it drives the synchronization rod 6008 to slide downward. The synchronization rod 6008 pulls the connecting plate 6007 and the first limiting plate 6005 to move downward, so that the first limiting plate 6005 retracts into the first guide column 6002, and the first limiting plate 6005 no longer limits the cable 1002;

[0041] When the synchronization rod 6008 moves downward, the first rack 800 drives the gear 8001 to rotate, and the gear 8001 drives the second rack 8002 to move upward, and the second rack 8002 drives the top plate 8003 and the second limit plate 7002 to move upward, so that the second limit plate 7002 no longer limits the cable 1002. Then, the cylinder 500 drives the locking rod 5001 to retract, and the locking rod 5001 retracts from under the handle 1004 of the charging gun 1003, and then the charging gun 1003 is plugged into the car for charging;

[0042] After charging is completed, the user pulls out the charging gun 1003, winds the cable 1002 around the first limiting column 9006 and the second limiting column 9006 again, and then plugs the charging gun 1003 into the socket 4007. Then the cylinder 500 pushes out the locking rod 5001, and the locking rod 5001 is plugged under the handle 1004 of the charging gun 1003 to lock the handle 1004. In this way, the cable 1002 can be wound around the first guide column 6002 and the second guide column 700 to prevent the cable 1002 from falling to the ground.

[0043] In addition, when the vehicle is not parked in a suitable position and the length of the cable 1002 is not enough for the charging gun 1003 to be plugged into the vehicle, the threaded rod can be rotated to drive the base 200 to move. The base 200 drives the charging pile to move and adjust, which can further allow the charging gun 1003 to be closer to the vehicle for convenient charging. Embodiment 2:

[0044] Since the cable 1002 of the charging gun 1003 is relatively thick and is wound around the first guide column 6002 and the second guide column 700, it requires a lot of manual effort to remove it. In order to solve this problem, a detachment unit is provided in this embodiment. The detachment unit is provided on the outside of the side frame 400 and is used to push the cable 1002 to detach from the outside of the tensioning unit.

[0045] In the specific design, the disengagement unit includes a swivel 900 rotatably sleeved on the outside of the first guide column 6002, a spiral piece 9001 is fixedly connected to the outside of the swivel 9000, one end of the spiral piece 9001 is fixedly connected to a force-bearing plate 9002, a first side plate 9003 is fixedly connected to the outside of the force-bearing plate 9002, a second side plate 9005 is fixedly connected to the outside of the side frame 400, a third spring 9004 is connected between the first side plate 9003 and the second side plate 9005, and a limiting column 9006 is fixedly connected to the bottom of the force-bearing plate 9002 corresponding to the outside of the side frame 400. In the above technical solution, the rotation of the swivel 900 is mainly used to drive the spiral piece 9001 to rotate. Due to the spiral structure of the spiral piece 9001, when the spiral piece 9001 rotates, the cable 1002 will be squeezed out from the outside of the first guide column 6002, so that the cable 1002 is automatically detached without manual manipulation.

[0046] In a further design, a push plate 8004 is fixedly connected to the top of the top plate 8003, a resistance block 1000 is penetrated through the push plate 8004, a first bevel 10001 is provided at one end of the resistance block 1000, a convex plate 10002 is fixedly connected to the outside of the resistance block 1000, a fourth spring 10003 is connected between the convex plate 10002 and the top plate 8003, an inclined plate 9007 is fixedly connected to one end of the spiral piece 9001, and the setting of the inclined plate 9007 facilitates the cable 1002 to be pushed out after the spiral piece 9001 rotates.

[0047] The specific principles in this example are as follows:

[0048] When the first limit plate 6005 and the second limit plate are retracted and no longer limit the cable 1002, the second limit plate 7002 drives the top plate 8003 to move upward, and the top plate 8003 drives the push plate 8004 to move upward, and the push plate 8004 drives the resistance block 1000 to move upward. After the resistance block 1000 moves upward for a certain distance, it will resist the force plate 9002. After the force plate 9002 is subjected to force, it will rotate upward, thereby driving the swivel 900 to rotate. Please refer to the attached figure. Fig.16 In the state shown in FIG. 1 , after the rotating ring 900 rotates, the spiral piece 9001 is driven to rotate. Due to the spiral structure of the spiral piece 9001, when the spiral piece 9001 rotates, the cable 1002 is squeezed out from the outside of the first guide column 6002, so that the cable 1002 is automatically removed without manual manipulation;

[0049] In addition, as the push plate 8004 continues to move upward, the force plate 9002 will be separated from the resistance block 1000, and the resistance block 1000 will no longer resist the force plate 9002. The force plate 9002 is pushed by the third spring 9004 to rotate and return to the initial position, and the force plate 9002 resists the outside of the limit column 9006.

[0050] When the push plate 8004 moves downward, under the action of the first bevel 10001 on the outside of the resistance block 1000, the resistance block 1000 resists the force plate 9002 (the force plate 9002 is restrained by the limiting column 9006 and thus does not move), the resistance block 1000 will retract and stretch the fourth spring 10003 until the top plate 8003 is below the force plate 9002 when moving, and then the resistance block 1000 will be pushed out again under the elastic force of the fourth spring 10003.

[0051] Embodiment three:

[0052] The difference between this embodiment and the first embodiment is that this embodiment is to determine whether the cable 1002 is wrapped around the outside of the first guide column 6002 when returning the charging gun 1003;

[0053] In a specific technical solution, a fixing sleeve 1100 is fixedly connected to the fixing ring 600. In order to realize the detection function of the second guide column 700, the fixing sleeve 1100 can also be fixedly connected to the outside of the side frame 400 and correspond to the second guide column 700.

[0054] In addition, a slide plate 11001 is slidably connected in the fixed sleeve 1100, the slide plate 11001 penetrates the fixed ring 600, one end of the slide plate 11001 is fixedly connected to a resistance rod 11003, and a pressure sensor 11005 is fixedly connected inside the fixed sleeve 1100. The pressure sensor 11005 is used to detect the pressure applied by the resistance rod 11003, and can also be replaced by a weighing sensor or a proximity switch;

[0055] Among them, a second bevel 11002 is also provided at one end of the skateboard 11001, and a control box 1001 is fixedly connected to the outside of the vertical charging pile 100. A control module is provided in the control box 1001. The pressure sensor 11005 is electrically coupled to the control module. A fifth spring 11004 is provided on the outside of the resistance rod 11003. The control module is an MCU control component, a PLC control component, an S7-200 control component or other control structure.

[0056] In addition, in order to facilitate the detection of the movement distance, a laser distance sensor 1200 is fixedly connected to the outside of the guide seat 7006, and the cylinder 500, the laser distance sensor 1200 and the control module are electrically coupled.

[0057] The above technical solution is explained as follows:

[0058] When returning the charging gun 1003, the user needs to wrap the cable 1002 around the outside of the first guide column 6002 and the second guide column 700. After the cable 1002 is wrapped around the first guide column 6002 and the second guide column 700, the cable 1002 will contact the second bevel 11002, allowing the slide plate 11001 to drive the contact rod 11003 to contact the pressure sensor 11005, so that the pressure sensor 11005 transmits a signal to the control module, and the control module controls the cylinder 500 to push the locking rod 5001 out to lock the charging gun 1003. If no pressure signal is detected, it is determined that the cable 1002 is not wrapped around the outside of the first guide column 6002 and the second guide column 700, and thus it cannot be locked. Therefore, the user must wrap and store the cable 1002 before returning the charging gun 1003.
