Description

Technical Field

[0001] This application relates to the field of charging piles, and more particularly to a protection structure for a charging gun of a new energy charging pile. Background Art

[0002] Currently, new energy vehicles refer to vehicles that use unconventional vehicle fuels as the power source to meet the needs of environmental protection and the oil crisis, and reduce or abandon the current mainstream models that burn traditional gasoline or diesel to drive internal combustion engines. Among them, pure electric vehicles need to use a charging gun to charge the electric vehicle. The charging gun serves as an interface between the charging device and the charging battery of the electric vehicle; The authorized announcement number is CN214112303U, and the authorized announcement date is September 3, 2021. It discloses a protection mechanism for a charging gun of a new energy electric vehicle, including a protection box. Screw rods are symmetrically and rotatably arranged on the side walls at both ends of the protection box. Fixed plates are rotatably arranged at the ends of the screw rods. Sliding plates are symmetrically fixed on the side walls at both ends of the protection box. Fixed springs are symmetrically fixed on the side walls of the two fixed plates. Clamping plates are fixed at the ends of the two fixed springs. A charging gun is arranged between the clamping plates. A protective cover is arranged at the end of the charging gun. Second limit blocks are symmetrically fixed on the side wall of the charging gun. An anti-collision sleeve is arranged on the side wall of the charging gun. First limit blocks are symmetrically fixed on the side wall of the protection box. Placing blocks and blocking blocks are symmetrically fixed on the side walls at both ends of the protection box. Stable springs are fixed on the upper surfaces of the placing blocks. Stable plates are fixed at the ends of the stable springs. The charging gun is comprehensively protected by the clamping plates, limit blocks, and stable plates in the protection box. The charging gun itself is also provided with an anti-collision sleeve and a protective cover for self-protection; The above-mentioned existing technical solutions have the following defects: When using the charging gun, first pull the doorknob to open the box door, then rotate the two rotating heads to make the screw rods rotate. The two screw rods rotate to control the two fixed plates to slide along the sliding plates. The fixed plates pull the fixed springs to make the clamping plates move away from the charging gun, and the charging gun can be taken out by sliding it upward. The operation is cumbersome, time-consuming and laborious. And when putting the charging gun back, another wave of operations is required, which may cause the user to directly discard it without putting it back. Summary of the Invention

[0003] This application aims to solve at least one of the technical problems existing in the prior art. According to the protection structure for a charging gun of a new energy charging pile in an embodiment of this application, it includes a support frame, a new energy charging pile, a retracting mechanism, and a protection mechanism; The support frame includes a vertical rod and a slide rail. The slide rail is installed at the upper end of the vertical rod, and a slider is installed on the surface of the slide rail; The new energy charging pile includes a pile body and a gun body. The pile body is fixed to the slider. A gun slot is opened on the outer surface of the pile body. One end of the gun body is clamped at the gun slot. The other end of the gun body is connected to a wire, and one end of the wire extends into the pile body; The retracting mechanism includes a retracting wheel and a forward and reverse motor. The retracting wheel is rotatably installed in the pile body. The driving shaft of the forward and reverse motor is in transmission connection with the retracting wheel.

One end of the retractable cover is slidably inserted into the chute. The movable end of the electric push rod is connected to the retractable cover. The retractable cover covers above the gun slot.

[0004] According to the charging gun protection structure of the new energy charging pile in the embodiment of the present application, the pile body is slidably installed on the slide rail. By sliding the pile body above the vehicle charging port, when the gun body is inserted into the vehicle charging port for charging, the wire is in a suspended state and will not drag on the ground, avoiding the possibility of the wire being trampled or run over by the vehicle, and prolonging the service life of the wire. Because the wire is in a vertical state, when the gun body is separated from the charging port, the gun body will not fall to the ground, avoiding the gun body being dropped and damaged, and playing a protective role for the gun body. The wire is retracted and released by a retracting wheel and driven by an electronically controlled forward and reverse motor, and is stored in the pile body, avoiding wind and sun exposure, prolonging the service life of the wire, and avoiding the traditional wire stacking and winding. The retracting and releasing operation can be realized through the control button on the surface of the gun body, solving the problem of cumbersome wire storage for the traditional gun body. A retractable cover is arranged above the gun slot to protect the placed gun body from wind and rain, and a sensor is installed at the gun slot. When the gun body is pulled out from the gun slot, the sensor transmits the pulling-out signal to the controller, and the controller controls the electric push rod to pull the retractable cover to slide back into the pile body, exposing the gun slot, facilitating the user to dock the gun body with the gun slot after using the gun body, and avoiding the retractable cover blocking and unable to engage with the gun slot. When the gun body is engaged in the gun slot, the sensor transmits this signal to the controller, and the controller controls the electric push rod to push the retractable cover out again to cover the outer surface of the gun body, playing a protective role, without redundant operations and being convenient to use.

[0005] In addition, the charging gun protection structure of the new energy charging pile according to the embodiment of the present application further has the following additional technical features: In a preferred mode of the present invention, one end of the slide rail is rotatably connected to the upper end of the vertical rod.

The pile body 300 is fixed to the slider 131. A gun slot 301 is formed on the outer surface of the pile body 300. One end of the gun body 500 is clamped at the gun slot 301. The other end of the gun body 500 is connected with a wire, and one end of the wire extends into the pile body 300; The retracting mechanism 310 includes a retracting wheel 311 and a forward and reverse motor 313.

When the gun body 500 is engaged at the gun slot 301, the sensor transmits this signal to the controller, and the controller controls the electric push rod 333 to push the retractable cover 331 to slide out and cover the outer surface of the gun body 500, playing a protective role, without redundant operation and being convenient to use.

[0041] Since the gun body 500 is not returned to its original position after use and is often discarded randomly, the protection mechanism 330 fails to play a protective role, the charging port of the gun body 500 is exposed, allowing dust and impurities to enter, and even dropping to the ground, resulting in soil, sand and gravel blocking the charging port of the gun body 500, affecting the use, and seriously causing water ingress and short - circuit damage. Therefore, the following is a specific implementation plan of the charging gun protection structure of the new energy charging pile according to the present application with reference to the attached drawings: Specifically, as Figures 5 - 9 shown, in a specific embodiment of the present invention, the gun body 500 includes a handheld part 510 and a plug 530. One end of the handheld part 510 is provided with a receiving groove 511, one end of the plug 530 is slidably inserted into the receiving groove 511, and a tension spring 513 for pulling the plug 530 is arranged in the receiving groove 511.

[0042] In a specific embodiment of the present invention, a cover plate 550 covers the port of the receiving groove 511. The cover plate 550 is hinged to the surface of the handheld part 510. A toothed groove 531 is formed on the surface of the plug 530, and a gear 551 is fixed on the cover plate 550. The gear 551 meshes with the toothed groove 531; a handle 570 for pushing the plug 530 out of the receiving groove 511 is installed outside the handheld part 510.

[0043] By holding the handheld part 510 and pulling the handle 570 to drive the plug 530 to slide out, the plug 530 is docked and inserted into the vehicle charging port for charging. After charging is completed, the pulled - out plug 530 is retracted into the receiving groove 511 under the pulling force of the tension spring 513. At the same time, the toothed groove 531 pushes the gear 551 to rotate, so that the cover plate 550 covers the port of the receiving groove 511 to protect the plug 530, avoiding the plug 530 being exposed outside. Even if the gun body 500 is not put back into the pile body 300, it can play a protective role, improving the safety and portability of the gun body 500. And if the sensor does not receive the information that the gun body 500 returns to its original position for a long time, the controller will control the forward and reverse motor 313 to drive and wind up the wire, so that the gun body 500 is in a suspended state after being recycled, avoiding being trampled or crushed on the ground.

[0044] In a specific embodiment of the present invention, the toothed groove 531 is opened along the sliding direction of the plug 530. A hinge 553 is installed at the connection between the cover plate 550 and the handheld part 510, and the gear 551 is coaxially arranged with the hinge 553.

[0047] When the plug 530 is inserted into the vehicle charging port, the vehicle charging port pushes the wedge block 516, causing the wedge block 516 to move upward and drive the lever 515 to rotate around the hinge point, simultaneously pushing the limit block 517 downward, so that the lower end of the limit block 517 abuts against the plug 530 to limit the sliding of the plug 530, and at the same time compress the compression spring 518. When the plug 530 is pulled out, the wedge block 516 is not under external force, and the compressed compression spring 518 pushes the wedge block 516 to reset, simultaneously driving the lower end of the limit block 517 to separate from the plug 530, so that the plug 530 is pulled back into the receiving groove 511 by the tension spring 513, protecting the plug 530 without manual operation, saving time and effort in charging, and reducing damage to the gun body 500.
