In summary, only when the two rear wheels of the new energy vehicle are on the first carrier plate 4 and the second carrier plate 5 at the same time, can the charging operation be completed, thereby eliminating the problems of random parking and irregular parking of new energy vehicles during charging.

[0025] Furthermore, the storage mechanism 3 includes a plurality of cable pushing units, which are respectively arranged on the inner side walls of the shell 11 from top to bottom. When the storage mechanism 3 is in a locked state, the plurality of cable pushing units make the cable 12 wavy.

[0026] In this optional embodiment, combined with Figure 3 As shown, the cable 12 is made wavy by a plurality of cable pushing units, thereby achieving storage of the cable 12 in the housing 11 .

[0027] Optionally, the cable pushing unit includes a cylinder 31, a piston 32, a wire clamping wheel 33, a piston rod 34, a wheel seat 35, a first spring 36, a first hole blocking mechanism 37 and a second hole blocking mechanism 38.

[0028] Optionally, the first hole blocking mechanism 37 and the second hole blocking mechanism 38 have the same structure, and the second hole blocking mechanism 38 includes a pull rod 381, a second spring 382, ​​a sealing block 383, a baffle 384 and a bracket 385, the bracket 385 is connected to the inner wall of the air inlet hole 311, the pull rod 381 is slidably connected to the bracket 385, the end of the pull rod 381 extending into the cylinder 31 is connected to the baffle 384, the end of the pull rod 381 passing through the air inlet hole 311 is connected to the sealing block 383, the second spring 382 is sleeved on the pull rod 381, and the two ends of the second spring 382 respectively abut against the opposite surfaces of the baffle 384 and the bracket 385, when the storage mechanism 3 is in a locked state, the sealing block 383 is used to block the air inlet hole 311, and when the storage mechanism 3 is in an unlocked state, the sealing block 383 releases the blockage of the air inlet hole 311.

[0029] Furthermore, the second carrier plate 5 has the same structure as the first carrier plate 4. The first carrier plate 4 includes a plate body 41 and a third spring 42. The lower surface of the plate body 41 is connected to one end of the third spring 42, and the other end of the third spring 42 is used to connect to the inner bottom surface of the pit.

[0030] Specifically, one end of the plate 41 can be set as a slope structure to facilitate the rear wheels of the new energy vehicle to drive on, and the other end of the plate 41 can be set as a raised structure to prevent the rear wheels of the new energy vehicle from falling out of the plate 41.

[0031] Optionally, the new energy vehicle charging pile also includes a first driving mechanism 6 and a second driving mechanism 8. The second driving mechanism 8 has the same structure as the first driving mechanism 6. One end of the transmission chain of the first driving mechanism 6 and the second driving mechanism 8 is respectively connected to the first carrier plate 4 and the second carrier plate 5, and the other end of the transmission of the first driving mechanism 6 and the second driving mechanism 8 is respectively connected to the sealing block 383 in the second hole blocking mechanism 38 and the first hole blocking mechanism 37.

[0032] Furthermore, the first driving mechanism 6 includes a trigger assembly 61, a wire rope 62, a moving rod 63, a pull rope 64, a guide wheel 65 and a pulley 66. The trigger assembly 61 includes a gear rod and a gear. The gear rod is vertically arranged and connected to the lower surface of the plate body 41. The gear is meshed with the gear rod. The gear is rotatably connected to the inner bottom surface of the pit through a winding shaft. One end of the wire rope 62 is wound around the winding shaft, and the other end of the wire rope 62 is connected to one end of the moving rod 63 after passing around the pulley 66. The other end of the moving rod 63 is connected to one end of multiple pull ropes 64, and the other ends of the multiple pull ropes 64 are respectively connected to the corresponding sealing blocks 383. Both sides of the moving rod 63 are in rolling contact with the guide wheel 65, and the guide wheel 65 is rotatably connected to the inner wall of the shell 11.

[0033] In this optional embodiment, combined with Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the steel wire rope 62 in the first driving mechanism 6 can be buried under the ground through a pipeline, and is connected to the moving rod 63 after being redirected by the rope pulley 66. When the rear wheel corresponding to the new energy vehicle has not driven onto the first carrier plate 4, the third spring 42 is in a natural state, and the plate body 41 is at a certain distance from the ground. When the rear wheel corresponding to the new energy vehicle drives onto the first carrier plate 4, the plate body 41 descends until it contacts the ground. At this time, the gear rod descends to drive the gear to rotate, thereby driving the winding shaft to rotate and wrap one end of the steel wire rope 62. Under the limiting guiding action of the guide wheel 65, the other end of the steel wire rope 62 pulls the moving rod 63 to move vertically downward, thereby pulling the sealing block 383 in the second hole blocking mechanism 38 downward through the pull rope 64, so that the air inlet 311 is opened. Similarly, The second driving mechanism 8 can open the air outlet 312, so that the piston 32 can move in the cylinder 31 when pushed by an external force. The charging gun is held by hand to pull the cable 12 out of the shell 11. During the pulling process, the cable 12 will exert a force on the wire clamping wheel 33, thereby pushing the piston 32 to move toward the inner wall of the shell 11 through the piston rod 34. At this time, the first spring 36 is compressed, so that the cable 12 is gradually released, so that the charging gun can be smoothly plugged into the charging port of the new energy vehicle. After the hand leaves the charging gun, the first spring 36 recovers slightly due to the release of the external force, and the cable 12 is pushed a certain distance through the wire clamping wheel 33 until a balanced state is reached, so that the cable 12 located outside the shell 11 is in a slightly taut state, such as Figure 1 As shown, the cable 12 is prevented from being dragged on the ground, and the cable 12 located outside the housing 11 is prevented from coming into contact with dirt and water stains on the ground, thereby increasing the service life of the cable 12.

[0034] Optionally, the new energy vehicle charging pile also includes a reinforcement block 7, which is set to a triangular structure. Two side surfaces of the reinforcement block 7 are respectively connected to the cylinder 31 and the inner wall of the shell 11. A blowing hole 72 is provided on the other side of the reinforcement block 7. The blowing hole 72 is inclined downward toward the inner middle part of the shell 11. A cavity 71 connected to the blowing hole 72 is provided in the reinforcement block 7, and the air outlet 312 is connected to the cavity 71.

[0035] In this optional embodiment, the reinforcement block 7 can be arranged under each cylinder 31 to improve the connection firmness between the cylinder 31 and the inner wall of the shell 11, thereby improving the service life of the entire storage mechanism 3. At the same time, when the piston 32 moves toward the inner wall of the shell 11, at this time, the sealing block 383 on the first hole blocking mechanism 37 does not block the air outlet 312, so that the gas in the cylinder 31 enters the cavity 71 through the air outlet 312, and then blows toward the corresponding part of the surface of the cable 12 through the air hole 72, thereby being able to blow away the dust on the surface of the cable 12. At this time, the cable 12 is gradually pulled out of the shell 11 along with the charging gun, and a cleaner cable 12 helps to improve the user experience.

[0036] Furthermore, the periphery of the cable clamping wheel 33 is provided with an annular groove for the cable 12 to be clamped into.

[0037] In this optional embodiment, combined with Figure 8 As shown, by inserting the cable 12 into the annular groove, the cable 12 is limited in position to prevent the cable 12 from shaking in the Y-axis direction.

[0038] The embodiment of the present invention further provides a method for using a new energy vehicle charging pile, based on the above new energy vehicle charging pile, comprising the following steps: S1: driving the two rear wheels of the new energy vehicle onto the first carrier plate 4 and the second carrier plate 5; S2: Pull out the charging gun from the charging pile body 1, so that the cable 12 follows the movement of the charging gun and is pulled out of the housing 11, until the charging gun is inserted into the charging port of the new energy vehicle for charging; S3: After charging is completed, the charging gun is placed back on the charging pile body 1, so that the two rear wheels of the new energy vehicle are driven off the first carrier plate 4 and the second carrier plate 5.

[0039] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
