Description

Technical Field

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

[0002] Currently, new energy vehicles refer to vehicles that use unconventional vehicle fuels as a power source. This is to cope with the needs of environmental protection and the oil crisis, and to 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 the interface between the charging equipment and the electric vehicle's battery.

[0003] Authorization announcement number CN214112303U, authorization announcement date 2021.09.03, discloses a charging gun protection mechanism for new energy electric vehicles, including a protective box. Screws are symmetrically and rotatably mounted on the side walls of both ends of the protective box. Fixed plates are rotatably mounted on the ends of the screws. Slide plates are symmetrically fixed on the side walls of both ends of the protective box. Fixed springs are symmetrically fixed on the side walls of the two fixed plates. Clamping plates are fixed to the ends of the two fixed springs. A charging gun is positioned between the clamping plates. A protective cover is provided at the end of the charging gun. A second limiting block is symmetrically fixed on the side wall of the charging gun. An anti-collision sleeve is provided on the side wall of the charging gun. A first limiting block is symmetrically fixed on the side wall of the protective box. Placement blocks and stop blocks are symmetrically fixed on the side walls of both ends of the protective box. A stabilizing spring is fixed to the upper surface of each placement block. A stabilizing plate is fixed to the end of each stabilizing spring. The clamping plates, limiting blocks, and stabilizing plates inside the protective box provide all-around protection for the charging gun. The charging gun itself is also protected by an anti-collision sleeve and a protective cover.

[0004] The existing technical solutions mentioned above have the following drawbacks: When using the charging gun, first pull the door handle to open the cabinet door, then turn the two rotating heads to make the screws rotate. The rotation of the two screws controls the two fixing plates to slide along the slide plate. The fixing plates pull the fixing spring to make the clamp plate move away from the charging gun. The charging gun can be taken out by sliding it upward. The operation is cumbersome, time-consuming and laborious. Furthermore, a series of operations are required when putting the charging gun back, which may cause the user to simply discard it without putting it back. Summary of the Invention

[0005] This application aims to at least solve one of the technical problems existing in the prior art. According to an embodiment of this application, a protective structure for a charging gun in a new energy charging pile includes a support frame, a new energy charging pile, a winding mechanism, and a protective mechanism.

[0006] The support frame includes an upright and a slide rail. The slide rail is installed on the upper end of the upright, and a slider is installed on the surface of the slide rail.

[0007] The new energy charging pile includes a pile body and a gun body. The pile body is fixed to the slider. A gun groove is opened on the outer surface of the pile body. One end of the gun body is snapped into the gun groove. The other end of the gun body is connected to a wire. One end of the wire extends into the pile body.

[0008] The winding mechanism includes a winding wheel and a forward / reverse motor. The winding wheel is rotatably mounted inside the pile body. The drive shaft of the forward / reverse motor is connected to the winding wheel. The wire is wound around the surface of the winding wheel. The protective mechanism includes a shrink cover and an electric push rod. A groove is provided on the surface of the pile body. One end of the shrink cover is slidably inserted into the groove. The movable end of the electric push rod is connected to the shrink cover. The shrink cover is positioned above the gun groove.

[0009] According to the protective structure of the charging gun of the new energy charging pile in this application embodiment, the pile body is slidably installed on the slide rail. By sliding the pile body above the car charging port, the wire is suspended in the air when the gun body is inserted into the car charging port for charging. It will not drag on the ground, avoiding the possibility of the wire being stepped on or run over by the car, thus extending the service life of the wire. Because the wire is in a vertical state, the gun body will not fall to the ground when it is removed from the charging port, thus preventing the gun body from falling and breaking and protecting the gun body.

[0010] The wire is wound and unwound using a reel driven by an electrically controlled forward and reverse motor. It is stored inside the pile, avoiding exposure to wind and sun, extending the service life of the wire, and avoiding the tangling and stacking of traditional wires. The winding and unwound operation can be achieved through the control button on the surface of the gun body, solving the problem of cumbersome wire storage in traditional gun bodies.

[0011] A retractable cover is installed above the gun slot to protect the placed gun body from wind and rain. A sensor is installed at the gun slot. When the gun body is pulled out of the slot, the sensor transmits a signal to the controller. The controller then controls the electric push rod to pull the retractable cover back into the pile body, exposing the gun slot. This makes it easy for the user to connect the gun body to the slot after use, preventing the retractable cover from obstructing the engagement. When the gun body is engaged in the slot, the sensor transmits the signal to the controller. The controller then controls the electric push rod to push the retractable cover out and onto the outer surface of the gun body, providing protection. No extra operation is required, making it convenient to use.

[0012] In addition, the protective structure for the charging gun of the new energy charging pile according to the embodiments of this application also has the following additional technical features:

[0013] In a preferred embodiment of the present invention, one end of the slide rail is rotatably connected to the upper end of the upright, the slide rail is horizontally arranged, and the surface of the slider is fixed with a mounting seat for fixing the pile.

[0014] In a preferred embodiment of the present invention, a rotating rod is rotatably mounted on the upper end of the upright, the upper end of the rotating rod is fixed to the slide rail, and a reduction motor for driving the rotating rod to rotate is fixed on the upper end of the upright.

[0015] In a preferred embodiment of the present invention, a worm gear is coaxially fixed to the rotating rod, and a worm is coaxially fixed to the drive shaft of the geared motor, with the worm gear meshing with the worm.

[0016] In a preferred embodiment of the present invention, a cavity is formed in the pile body, the winding wheel is disposed in the cavity, and the forward and reverse motor is fixedly connected to the pile body.

[0017] In a preferred embodiment of the present invention, the take-up reel is coaxially provided with a rotating shaft, the end of the rotating shaft is rotatably mounted in the cavity via a bearing, the rotating shaft is coaxially fixed with a driven wheel, the drive shaft of the forward and reverse motor is coaxially fixed with a driving wheel, and the driving wheel meshes with the driven wheel.

[0018] In a preferred embodiment of the present invention, the side wall of the pile body is provided with a wire groove for the wire to pass through, a guide wheel is installed inside the wire groove, and a limit switch for controlling the number of rotations of the winding wheel is installed inside the pile body.

[0019] In a preferred embodiment of the present invention, the take-up reel is rotatably sleeved on the surface of the rotating shaft, a torsion spring is connected between the take-up reel and the rotating shaft, and the shrink cover has a semi-circular cross-section that wraps around the top of the gun body.

[0020] In a preferred embodiment of the present invention, the fixed end of the electric push rod is connected to the pile body, and the electric push rod is disposed within the pile body.

[0021] In a preferred embodiment of the present invention, the movable end of the electric push rod is hinged to a connecting rod, the other end of the connecting rod is hinged to the retractable cover, and a sensor for sensing the gun body is installed at the gun slot.

[0022] Because the charging gun is often not returned to its original position after use and is frequently left lying around, the protective mechanism fails to function properly. The charging port is exposed, allowing dust and impurities to enter, and even falling to the ground, causing dirt and sand to clog the charging port, affecting its use. In severe cases, it can lead to water ingress and short circuit damage. Therefore, this application proposes a specific implementation plan for the protective structure of the charging gun in new energy charging piles:

[0023] In a preferred embodiment of the present invention, the gun body includes a handheld part and a plug. One end of the handheld part is provided with a receiving groove, and one end of the plug is slidably inserted into the receiving groove. A tension spring for pulling the plug is provided in the receiving groove.

[0024] In a preferred embodiment of the present invention, a cover plate is provided at the port of the receiving slot, the cover plate is hinged to the surface of the handheld part, the surface of the plug is provided with a toothed groove, a gear is fixed to the cover plate, and the gear meshes with the toothed groove; a handle for pushing the plug out of the receiving slot is installed on the outside of the handheld part.

[0025] By holding the handpiece and turning the handle, the plug slides out and engages with the car's charging port for charging. After charging is complete, the unplugged plug retracts into the receiving slot due to the tension of the spring. At the same time, the toothed groove drives the gear to rotate, causing the cover to close on the receiving slot port, protecting the plug and preventing it from being exposed. Even if the gun body is not returned to the charging station, it still provides protection, improving the safety and portability of the gun body. Furthermore, if the sensor does not receive the gun body's return information for an extended period, the controller will control the forward and reverse motor drive to rewind the wire, ensuring that the gun body is suspended in the air after being retrieved, preventing it from being stepped on or run over on the ground.

[0026] In a preferred embodiment of the present invention, the toothed groove is formed along the sliding direction of the plug, a hinge is installed at the connection between the cover plate and the handheld part, and the gear is coaxially arranged with the hinge.

[0027] In a preferred embodiment of the present invention, a tension spring groove is provided at the bottom of the receiving groove, one end of the tension spring is fixed in the tension spring groove, and the other end of the tension spring is connected to the plug. Two tension springs are symmetrically arranged.

[0028] When the plug is not subjected to external force, it will be pulled back into the receiving groove by the tension spring. This can cause the plug to fail to be secured when charging a car. Therefore, according to the specific implementation plan of the protective structure for the charging gun of the new energy charging pile in this application:

[0029] In a preferred embodiment of the present invention, a cavity is provided at one end of the handheld part, and a lever is rotatably installed in the cavity. A wedge is fixed at one end of the lever, and a limit block is fixed at the other end of the lever. The lower end of the wedge extends to the outside of the front end of the handheld part, and the lower end of the limit block abuts against the end of the plug. A compression spring is fixed at the upper end of the wedge, and the upper end of the compression spring abuts against the inner wall of the handheld part.

[0030] When the plug is inserted into the car charging port, the charging port pushes the wedge, causing the wedge to move upward and rotate the lever around the hinge point. Simultaneously, it pushes the limit block downward, causing the lower end of the limit block to abut against the plug, restricting the plug from sliding. At the same time, it compresses the compression spring. When the plug is pulled out, the wedge is no longer subjected to external force, and the compressed spring pushes the wedge to reset. Simultaneously, it causes the lower end of the limit block to separate from the plug, allowing the plug to be pulled back into the receiving groove by the tension spring. This protects the plug without manual operation, making charging time-saving and labor-saving, and reducing damage to the charging gun.

[0031] In a preferred embodiment of the present invention, a limiting plate is fixed to one end of the plug, the limiting plate is disposed in the receiving groove, the end of the receiving groove is provided with a limiting protrusion for restricting the limiting plate from disengaging, and a buffer block is fixed to the back of the limiting plate, the buffer block being disposed opposite to the inner wall of the receiving groove.

[0032] In a preferred embodiment of the present invention, a scissor-type telescopic frame is installed in the receiving groove. The scissor-type telescopic frame includes a connecting rod A and a connecting rod B. The connecting rod A and the connecting rod B are arranged to cross each other, and a pin is rotatably connected at the intersection of the connecting rod A and the connecting rod B.

[0033] One end of the connecting rod A is hinged to the inner wall of the receiving groove, and the other end of the connecting rod A is equipped with a roller A, which makes rolling contact with the surface of the limiting block;

[0034] One end of the connecting rod B is hinged to the limiting block, and the other end of the connecting rod B is equipped with a roller B, which makes rolling contact with the inner wall of the receiving groove.

[0035] One end of the connecting rod B is fixed with a steel wire rope, and the other end of the steel wire rope is fixedly connected to the handle. A hinge shaft is installed at the hinge joint between the outer wall of the handle and the hand grip.

[0036] In a preferred embodiment of the present invention, a sealing gasket is provided on the inner surface of the cover plate, and the sealing gasket is sealed and fitted to the plug port.

[0037] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0050] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0052] The following describes a protective structure for a charging gun in a new energy charging pile according to an embodiment of this application, with reference to the accompanying drawings.

[0053] like Figures 1-10 As shown, the protective structure for the charging gun of the new energy charging pile according to the embodiment of this application includes a support frame 100, a new energy charging pile, a winding mechanism 310, and a protective mechanism 330.

[0054] The support frame 100 includes a vertical rod 110 and a slide rail 130. The slide rail 130 is installed on the upper end of the vertical rod 110, and a slider 131 is installed on the surface of the slide rail 130.

[0055] The new energy charging pile includes a pile body 300 and a gun body 500. The pile body 300 is fixed to the slider 131. A gun groove 301 is opened on the outer surface of the pile body 300. One end of the gun body 500 is snapped into the gun groove 301. The other end of the gun body 500 is connected to a wire. One end of the wire extends into the pile body 300.

[0056] The winding mechanism 310 includes a winding wheel 311 and a forward / reverse motor 313. The winding wheel 311 is rotatably mounted inside the pile body 300. The drive shaft of the forward / reverse motor 313 is connected to the winding wheel 311. The wire is wound around the surface of the winding wheel 311. The protective mechanism 330 includes a shrink cover 331 and an electric push rod 333. A groove is formed on the surface of the pile body 300. One end of the shrink cover 331 is slidably inserted into the groove. The movable end of the electric push rod 333 is connected to the shrink cover 331. The shrink cover 331 covers the gun slot 301.

[0057] According to the protective structure of the charging gun of the new energy charging pile in this application embodiment, the pile body 300 is slidably installed on the slide rail 130. By sliding the pile body 300 above the car charging port, when the gun body 500 is inserted into the car charging port, the wire is suspended in the air and will not drag on the ground, avoiding the possibility of the wire being stepped on or run over by a car, thus extending the service life of the wire. Because the wire is in a vertical state, the gun body 500 will not fall to the ground when it is removed from the charging port, thus preventing the gun body 500 from falling and breaking, and protecting the gun body 500.

[0058] The wire is wound and unwound using a winding wheel 311, driven by an electrically controlled forward and reverse motor 313. It is stored inside the pile body 300, avoiding wind and sun exposure, extending the service life of the wire, and avoiding the tangling of traditional wires. The winding and unwound operation can be achieved through the control button on the surface of the gun body 500, solving the problem of cumbersome wire storage in traditional gun bodies 500.

[0059] A retractable cover 331 is installed above the gun slot 301 to protect the placed gun body 500 from wind and rain. A sensor is installed at the gun slot 301. When the gun body 500 is pulled out of the gun slot 301, the sensor will transmit a signal to the controller. The controller will control the electric push rod 333 to pull the retractable cover 331 back into the pile body 300, exposing the gun slot 301. This makes it easy for the user to connect the gun body 500 to the gun slot 301 after use, and avoids the retractable cover 331 blocking the engagement with the gun slot 301. When the gun body 500 is engaged in the gun slot 301, the sensor will transmit the signal to the controller. The controller will again control the electric push rod 333 to push the retractable cover 331 out and cover the outer surface of the gun body 500, providing protection. No extra operation is required, making it convenient to use.

[0060] In addition, the protective structure for the charging gun of the new energy charging pile according to the embodiments of this application also has the following additional technical features:

[0061] In a specific embodiment of the present invention, one end of the slide rail 130 is rotatably connected to the upper end of the upright 110, the slide rail 130 is horizontally arranged, and the surface of the slider 131 is fixed with a mounting seat for fixing the pile body 300.

[0062] In a specific embodiment of the present invention, a rotating rod 111 is rotatably mounted on the upper end of the upright 110, the upper end of the rotating rod 111 is fixed to the slide rail 130, and a reduction motor 113 for driving the rotating rod 111 to rotate is fixed on the upper end of the upright 110.

[0063] In a specific embodiment of the present invention, a turbine is coaxially fixed to the rotating rod 111, and a worm gear is coaxially fixed to the drive shaft of the reduction motor 113, with the turbine gear meshing with the worm gear.

[0064] In a specific embodiment of the present invention, a cavity is provided inside the pile body 300, the winding wheel 311 is disposed in the cavity, and the forward and reverse motor 313 is fixedly connected to the pile body 300.

[0065] Specifically, such as Figures 2-3As shown, in a specific embodiment of the present invention, the take-up reel 311 is coaxially provided with a rotating shaft 315, the end of the rotating shaft 315 is rotatably mounted in the cavity through a bearing, the rotating shaft 315 is coaxially fixed with a driven wheel 317, the drive shaft of the forward and reverse motor 313 is coaxially fixed with a driving wheel 319, and the driving wheel 319 meshes with the driven wheel 317.

[0066] In a specific embodiment of the present invention, the side wall of the pile body 300 is provided with a wire groove for the wire to pass through, a guide wheel is installed inside the wire groove, and a limit switch for controlling the number of rotations of the winding wheel 311 is installed inside the pile body 300.

[0067] In a specific embodiment of the present invention, the winding wheel 311 is rotatably sleeved on the surface of the rotating shaft 315, a torsion spring is connected between the winding wheel 311 and the rotating shaft 315, and the shrink cover 331 has a semi-circular cross-section, which covers the upper part of the gun body 500.

[0068] In a specific embodiment of the present invention, the fixed end of the electric push rod 333 is connected to the pile body 300, and the electric push rod 333 is disposed inside the pile body 300.

[0069] In a specific embodiment of the present invention, the movable end of the electric push rod 333 is hinged to a connecting rod 335, the other end of the connecting rod 335 is hinged to the shrink cover 331, and a sensor for sensing the gun body 500 is installed at the gun groove 301.

[0070] Because the charging gun 500 is often not returned to its original position after use and is frequently left lying around, the protective mechanism 330 fails to provide protection. The charging port of the charging gun 500 is exposed, allowing dust and impurities to enter, and even falling to the ground, causing dirt and sand to clog the charging port, affecting its use. In severe cases, it can lead to water ingress and short circuit damage. Therefore, the following is a specific implementation plan for the protective structure of the charging gun in this application, referring to the attached diagram:

[0071] Specifically, such as Figures 5-9 As 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, and one end of the plug 530 is slidably inserted into the receiving groove 511. A tension spring 513 for pulling the plug 530 is provided in the receiving groove 511.

[0072] In a specific embodiment of the present invention, a cover plate 550 is provided at 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 provided on the surface of the plug 530. A gear 551 is fixed on the cover plate 550 and meshes with the toothed groove 531. A handle 570 for pushing the plug 530 out of the receiving groove 511 is installed on the outside of the handheld part 510.

[0073] By holding the handpiece 510 and turning the handle 570, the plug 530 slides out and engages with the car charging port for charging. After charging is complete, the plug 530 retracts into the receiving groove 511 under the tension of the tension spring 513. At the same time, the toothed groove 531 drives the gear 551 to rotate, causing the cover plate 550 to cover the port of the receiving groove 511, protecting the plug 530 and preventing it from being exposed. Even if the gun body 500 is not returned to the pile body 300, it can still provide protection, improving the safety and portability of the gun body 500. Furthermore, if the sensor does not receive the gun body 500's return information for an extended period, the controller will control the forward and reverse motor 313 to rewind the wire, so that the gun body 500 is suspended in the air after being retracted, preventing it from being stepped on or run over on the ground.

[0074] In a specific embodiment of the present invention, the toothed groove 531 is opened along the sliding direction of the plug 530, and 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.

[0075] In a specific embodiment of the present invention, a tension spring groove is provided at the bottom of the receiving groove 511, one end of the tension spring 513 is fixed in the tension spring groove, and the other end of the tension spring 513 is connected to the plug 530. Two tension springs 513 are symmetrically arranged.

[0076] When the plug 530 is not subjected to external force, it will be pulled back into the receiving groove 511 by the tension spring 513. This will cause the plug 530 to be unable to be fixed when charging a car. Therefore, the following is a specific implementation scheme of the protective structure of the charging gun of the new energy charging pile according to the attached figure:

[0077] Specifically, such as Figure 7 , Figure 10As shown, in a specific embodiment of the present invention, a cavity is provided at one end of the handheld part 510, and a lever 515 is rotatably installed in the cavity. A wedge 516 is fixed at one end of the lever 515, and a limit block 517 is fixed at the other end of the lever 515. The lower end of the wedge 516 extends to the outside of the front end of the handheld part 510, and the lower end of the limit block 517 abuts against the end of the plug 530. A compression spring 518 is fixed at the upper end of the wedge 516, and the upper end of the compression spring 518 abuts against the inner wall of the handheld part 510.

[0078] When the plug 530 is inserted into the car charging port, the car charging port pushes the wedge 516, causing the wedge 516 to move upward and rotate the lever 515 around the hinge point. Simultaneously, the limiting block 517 moves downward, causing the lower end of the limiting block 517 to abut against the plug 530, restricting the plug 530 from sliding. At the same time, the compression spring 518 is compressed. When the plug 530 is pulled out, the wedge 516 is no longer subjected to external force, and the compressed spring 518 pushes the wedge 516 to reset. Simultaneously, the lower end of the limiting block 517 is separated from the plug 530, so that the plug 530 is pulled back into the receiving groove 511 by the tension spring 513. This protects the plug 530 without manual operation, making charging time-saving and labor-saving, and reducing damage to the gun body 500.

[0079] In a specific embodiment of the present invention, a limiting plate 533 is fixed to one end of the plug 530. The limiting plate 533 is disposed in the receiving groove 511. The end of the receiving groove 511 is provided with a limiting protrusion for restricting the limiting plate 533 from disengaging. A buffer block is fixed to the back of the limiting plate 533. The buffer block is disposed opposite to the inner wall of the receiving groove 511.

[0080] In a specific embodiment of the present invention, a scissor-type telescopic frame 590 is installed in the receiving groove 511. The scissor-type telescopic frame 590 includes a connecting rod A591 and a connecting rod B592. The connecting rod A591 and the connecting rod B592 are arranged to cross each other.
