Description

Technical Field

[0002] In the use of electric vehicle charging piles, in order to increase the use distance of the charging gun, the cable is usually wound up. When needed, the user only needs to pull it out from the charging pile. However, many users usually just hang up the charging gun directly after use, or even put the charging gun directly on the ground. At this time, the cable will be scattered on the ground and is easily damaged by rolling. Currently, a motor is usually installed inside the charging pile. After charging is completed, the motor is started to drive the cable to wind up, thereby avoiding the cable from being scattered outside, and then performing the operations of automatic retracting and anti-rolling to increase the service life of the cable.

[0003] In the aforementioned prior art, when winding up the cable, only simple linear winding can be performed, and the direction and angle of the wound-up cable cannot be changed. And charging piles are usually installed outdoors, where the outdoor environment is complex. Once there are some foreign objects or obstacles on the ground, the retracting path of the cable or the charging gun will be blocked or caught, affecting the normal winding up of the cable.

The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0029] Please refer toFigures 1 to 7 , the present invention provides an automatic retracting and anti-rolling device for an electric vehicle charging pile cable, which includes a charging pile box body 1, charging pile components 2, a charging gun 3, a charging cable 4, and an automatic retracting component.

The loosening prevention unit includes two moving frames 20, two moving frame drive mechanisms, and two abutting mechanisms. The oppositely moving mechanism and the moving frame 20 drive mechanism have the same structure, and both include an oppositely driving component 21, a connecting shaft 22, and two threaded rods 23.

[0030] Among them, the charging pile components 2 and the charging cable 4 are both arranged inside the charging pile box body 1. The charging gun is arranged at one end of the charging cable 4. The retracting unit is arranged inside the charging pile box body 1. The charging cable 4 is wound around the retracting unit. The other end of the charging cable 4 is connected to the charging pile components 2. The rotating plate 5 is rotatably connected to one side of the charging pile box body 1. The two telescopic components 6 are symmetrically arranged inside the rotating plate 5. The cable clamping unit is arranged at the output ends of the two telescopic components 6. After using the charging gun 3, the user casually places the charging gun 3 on the ground. At this time, the retracting unit is started to drive the charging cable 4 to wind up. At the same time, the cable clamping unit clamps the charging cable 4. At this time, the rotating plate 5 rotates, so that the charging cable 4 adjusts the angle. The telescopic component 6 drives the cable clamping unit to expand and contract, so that the charging cable 4 adjusts the height.

[0031] Secondly, the retracting drive component 7 is arranged inside the charging pile box body 1. The output end of the retracting drive component 7 is fixedly connected to the retracting shaft 8. The charging cable 4 is wound around the retracting shaft 8. The retracting drive component 7 is a self-locking motor. When the retracting drive component 7 is started, it drives the retracting shaft 8 to rotate, and then winds up and unwinds the wound charging cable 4.

[0032] Meanwhile, the two sliding grooves 9 are respectively arranged at the output ends of the corresponding telescopic components 6, the two opposite movement mechanisms are respectively arranged inside the corresponding sliding grooves 9, and the driving components 10 of the plurality of clamping shafts 11 are respectively slidably connected to the corresponding sliding grooves 9. The driving components 10 of the clamping shafts 11 are arranged on the opposite movement mechanisms, and the output ends of the driving components 10 of the clamping shafts 11 are fixedly connected to the clamping shafts 11. The driving components 10 of the clamping shafts 11 are self-locking motors. First, through the opposite movement mechanisms, the driving components 10 of the clamping shafts 11 are driven to slide in the sliding grooves 9, so that the two clamping shafts 11 move relatively, thereby holding the charging cable 4, avoiding loosening and deviation during the adjustment of the position and angle, and at the same time, when winding and unwinding, the clamping driving components can also be started to assist the movement of the charging cable 4, improving the winding and unwinding quality.

[0033] In addition, the rotating plate 5 is provided with a limiting groove 18 and a placement groove 19. The maintenance door panel 12 is arranged at one end of the charging pile box body 1. The rotating plate driving component 13 and the bracket 15 are both arranged on the inner side wall of the charging pile box body 1. The output end of the rotating plate driving component 13 penetrates through the charging pile box body 1 and is fixedly connected to the rotating plate 5. The operation panel 14 is arranged on one side of the charging pile box body 1. The limiting component 16 is arranged on the bracket 15, and the output end of the limiting component 16 is fixedly connected to the limiting block 17. The limiting block 17 is mutually adapted to the limiting groove 18, and the placement groove 19 is mutually adapted to the charging gun 3. By unscrewing the bolts to open the maintenance door panel 12, it is convenient to maintain the components of the charging gun 3 inside. The rotating plate driving component 13 is a self-locking motor, and the limiting component 16 is a self-locking cylinder. When it is necessary to rotate and adjust the angles of the charging gun 3 and the charging cable 4, first start the limiting component 16 to drive the limiting block 17 to disengage from the limiting groove 18, and then start the rotating plate driving component 13 to drive the rotating plate 5 to rotate, thereby realizing the angle adjustment; in addition, a camera is arranged outside the charging pile box body 1, so that the situation of the charging gun 3 on the ground can be photographed. When an obstacle is detected near the charging gun 3, the position and angle can be adjusted; in addition, after the charging gun 3 is retracted, since the charging cable 4 is always clamped between the two clamping shafts 11, at this time the charging gun 3 naturally drops and is stored in the placement groove 19 for subsequent use by the user; when the user uses it, by interacting with the operation panel 14, the charging pile can be used.

[0034] Then, the two mobile frames 20 are symmetrically arranged inside the charging pile box body 1. Drive mechanisms for the two mobile frames 20 are arranged on the two mobile frames 20, and the two abutting mechanisms are respectively arranged inside the corresponding mobile frames 20. The drive mechanism of the mobile frame 20 can drive the mobile frame 20 to move, thereby driving the abutting mechanism to abut against the charging cable 4.

[0035] Again, the clamping shaft 11 drive member 10 and the mobile frame 20 are both provided with threaded holes 24. The opposing drive member 21 is arranged at one end of the mobile frame 20. One ends of the two threaded rods 23 are symmetrically arranged at both ends of the connecting shaft 22, and the other ends of the two threaded rods 23 are respectively arranged on the corresponding mobile frames 20. The output end of the opposing drive member 21 is fixedly connected to the other end of the corresponding threaded rod 23, and the threaded rod 23 is mutually adapted to the threaded hole 24. When the charging cable 4 is in use, first, the opposing drive member 21 is started to drive the connecting shaft 22 and the two threaded rods 23 to rotate. Cooperating with the threaded hole 24, the two mobile frames 20 are driven to move relatively, thereby driving the abutting mechanism. Similarly for the clamping shaft 11, after the threaded rod 23 cooperates with the threaded hole 24, the clamping shaft 11 drive member 10 is driven to slide in the chute 9, so that the clamping shaft 11 moves.

[0036] Moreover, one end of the rotating block 25 is rotatably connected to the mobile frame 20, and a plurality of abutting blocks 26 are sequentially arranged at the other end of the rotating block 25. Both ends of the spring 27 are movably connected to the rotating block 25 and the inner wall of the mobile frame 20 respectively. After the mobile frame 20 moves, the rotating block 25 approaches the charging cable 4. At this time, the abutting block 26 contacts the charging cable 4, and the spring 27 provides an abutting force, thereby abutting against the charging cable 4 in contact, so that the charging cable 4 is restricted and cannot be naturally wound or unwound; especially after the user holds the charging gun 3 and pulls out the charging cable 4, the charging cable 4 cannot naturally retract into the charging pile box body 1, but the user only needs to apply a force greater than that of the spring 27 to still continue to drive the charging cable 4 to unwind, thereby realizing the winding and unwinding control of the charging cable 4.

[0037] Therefore, the charging gun 3 cleaning unit is arranged above the charging pile box body 1; the rain shield 28 is arranged above the charging pile box body, two transverse translation screw machines 29 are sequentially arranged inside the rain shield 28, the cleaning expansion component 30 is arranged at the output ends of the two transverse translation screw machines 29, and the output end of the cleaning expansion component 30 is fixedly connected to the cleaning mechanism. The rain shield 28 can shield the users using the charging pile below from rain. At the same time, after the charging pile is used, starting the transverse translation screw machine 29 can drive the cleaning expansion component 30 and the cleaning mechanism to move above the charging gun 3. Thus, the cleaning expansion component 30 drives the cleaning component to expand, and then the charging gun 3 is cleaned to avoid being contaminated by dust or foreign objects during long-term outdoor use.

[0038] Finally, the cleaning lifting component 31 is arranged at the output end of the cleaning expansion component 30, the output end of the cleaning lifting component 31 is fixedly connected to the cleaning V-shaped groove 32, the cleaning fan 33 and the metal block 34 are arranged on both sides of the cleaning V-shaped groove 32, a plurality of cleaning brushes 36 are sequentially arranged on the inner wall of the cleaning V-shaped groove 32, and the electromagnet 35 is arranged at the output end of the transverse translation screw machine 29. The cleaning lifting component 31 is a self-locking air cylinder. First, when the charging gun 3 needs to be cleaned, the charging cable 4 continuously contracts until the charging gun 3 is contracted to one side of the two clamping shafts 11. At this time, the cleaning lifting component 31 can be started to drive the cleaning V-shaped groove 32 to move downward. Then, relying on the cleaning brushes 36 to fit with the outer surface of the charging gun 3 and continuously moving to achieve the cleaning operation. At the same time, the cleaning fan 33 is started to blow away dust and foreign objects to assist in cleaning. After the cleaning is completed, the cleaning expansion component 30 is started again to drive the cleaning lifting component 31 back into the rain shield 28. At this time, the electromagnet 35 is energized to adsorb the metal block 34, so as to realize the storage of the cleaning mechanism.

[0039] When using an automatic retracting and anti-rolling device for an electric vehicle charging cable according to this embodiment, after the use of the charging gun 3 is completed, the user casually places the charging gun 3 on the ground. At this time, the retracting drive component 7 is activated to drive the retracting shaft 8 to rotate, thereby winding the wound charging cable 4. At the same time, a camera is provided outside the charging pile box body 1, so that the situation of the charging gun 3 on the ground can be photographed. When an obstacle is detected near the charging gun 3, the limiting component 16 is activated to drive the limiting block 17 to disengage from the limiting groove 18, and then the rotating plate drive component 13 is activated to drive the rotating plate 5 to rotate, thereby realizing angle adjustment. The telescopic component 6 drives the cable clamping unit to expand and contract, so that the height of the charging cable 4 is adjusted. In addition, after the charging gun 3 is retracted, since the charging cable 4 is always clamped between the two clamping shafts 11, the charging gun 3 then naturally hangs in the placement groove 19 for storage, so as to be taken by the user later.

[0040] Through the above structural settings, the angle and height of the wound charging cable 4 can be adjusted, so that obstacles can be avoided during winding, the winding success rate is significantly improved, and the charging cable 4 is prevented from being rolled over due to accumulation on the ground.

[0041] The above-disclosed are only one or more preferred embodiments of the present application, and the scope of rights of the present application cannot be limited thereby. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present application still fall within the scope covered by the present application.
