[0004] The existing electric vehicle charging pile technology has the following problems: during use, the existing electric vehicle charging piles are not firmly fixed and are very easy to topple over under external impact. Therefore, they need to be fixed to the ground or wall with bolts and other connectors, which is very destructive to the bottom surface and the wall. In addition, the charging piles are not easy to disassemble after installation, which makes it inconvenient to move the charging piles, so the mobility is poor. Summary of the invention

[0005] The purpose of the present invention is to provide a new energy energy-saving charging pile for electric vehicles to solve the problems of loose fixation, easy to tip over, and difficult to disassemble after installation proposed in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a new energy energy-saving charging pile for electric vehicles, comprising a charging pile base and a charging pile fixedly installed on the top surface of the charging pile base, support legs are fixedly connected to both sides of the charging pile base, a groove is provided on the bottom surface of the charging pile base, a piston cylinder matching the shape of the groove is placed in the groove, a suction cup is fixedly connected to the bottom surface of the piston cylinder, the piston cylinder is fixedly connected to the charging pile base by bolts, and an exhaust component is provided in the piston cylinder for extracting air in the suction cup to form a vacuum negative pressure environment when the bolts are tightened.

A spring receiving groove is provided on the inner bottom surface of the piston cylinder. A spring is fixedly connected to the bottom surface of the piston, and the bottom end of the spring is fixedly connected to the bottom surface of the spring receiving groove.

[0008] Preferably, the piston divides the internal space of the piston cylinder into an upper cavity and a lower cavity.

[0009] Preferably, the piston is provided with a gas channel communicating with the upper cavity, the bottom surface of the piston is fixedly connected with a hose, the bottom end of the hose is fixedly connected to the inner bottom surface of the piston cylinder, the top surface of the suction cup is provided with a through hole communicating with the inner side of the suction cup, the top end of the hose is communicated with the gas channel, and the bottom end of the hose is communicated with the through hole.

[0010] Preferably, an air guide hole communicating with the lower cavity is provided on one side outer wall of the piston cylinder.

[0011] Preferably, a limiting groove is provided on the inner wall of the groove, and a limiting plate matched with the limiting groove is fixedly connected to the outer wall of the piston cylinder.

[0012] Preferably, a first bolt hole is provided on the top surface of the charging pile base, and a second bolt hole corresponding to the first bolt hole is provided on the top surface of the piston cylinder. The bolt is threadedly connected to the charging pile base, and the bottom end of the bolt passes through the first bolt hole and the second bolt hole and abuts against the top surface of the piston.

[0014] Compared with the existing electric vehicle charging pile technology, the present invention provides a new energy energy-saving charging pile for electric vehicles, which has the following beneficial effects:

[0015] 1. The present invention arranges an exhaust assembly in the piston cylinder, and when the bolt is turned, the piston can be pushed to move downward. At this time, the air in the lower cavity is discharged from the air guide hole, so that the piston can continue to move downward in the piston cylinder, and the air in the suction cup is sucked into the upper cavity at the top of the piston through the through hole, the hose, and the gas channel. When the piston drops to a certain position, the air in the suction cup is sucked out, and at the same time, the hose is gradually bent as the piston drops and is finally flattened by the piston at the bottom end of the piston cylinder. At this time, the hose is no longer connected to the through hole and the gas channel, and plays a blocking role. At this time, the interior of the suction cup is a vacuum environment and is firmly adsorbed on the ground, which can fix the charging pile and prevent it from tipping over under external impact;

[0016] 2. When the bolt is rotated in the reverse direction, the piston of the present invention will move upward under the elastic action of the spring, so that the external air can be replenished into the lower cavity through the air guide hole, and the hose is no longer squeezed by the piston and is reconnected with the through hole and the gas channel. At the same time, the air in the upper cavity will enter the suction cup through the gas channel, the hose and the through hole due to the squeezing of the piston. At this time, the interior of the suction cup is no longer a vacuum environment, so it can be easily removed from the ground. At the same time, the charging pile base can be removed from the piston cylinder, which is convenient for quick disassembly and displacement of the charging pile. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] See also Figure 1-Figure 6 The present invention provides a technical solution: a new energy energy-saving charging pile for electric vehicles, comprising a charging pile base 1 and a charging pile 7 fixedly installed on the top surface of the charging pile base 1, wherein the four end corners of the bottom of the charging pile 7 are fixedly connected with fixing parts 8, and the top surface of the charging pile base 1 is provided with four fixing holes 3 corresponding to the fixing parts 8, and the fixing parts 8 are fixed by screws and threaded cooperation with the fixing holes 3, so that the charging pile 7 can be fixedly installed on the charging pile base 1.

[0027] It should be noted that support legs 2 are fixedly connected to both sides of the charging pile base 1, a groove 5 is provided on the bottom surface of the charging pile base 1, a piston cylinder 9 whose shape matches the groove 5 is placed in the groove 5, a limiting groove 6 is provided on the inner wall of the groove 5, a limiting plate 18 matching the limiting groove 6 is fixedly connected to the outer wall of the piston cylinder 9, a suction cup 10 is fixedly connected to the bottom surface of the piston cylinder 9, and the limiting groove 6 is engaged with the limiting plate 18 to keep the piston cylinder 9 at a fixed angle without displacement or rotation.

[0028] It is worth mentioning that the piston cylinder 9 is fixedly connected to the charging pile base 1 by a bolt 19. A first bolt hole 4 is provided on the top surface of the charging pile base 1, and a second bolt hole 17 corresponding to the first bolt hole 4 is provided on the top surface of the piston cylinder 9. The bolt 19 is threadedly connected to the charging pile base 1. The bottom end of the bolt 19 passes through the first bolt hole 4 and the second bolt hole 17 and abuts against the top surface of the piston 12. Then, when the bolt 19 continues to be rotated, the bolt 19 can press the piston 12 downward, causing the piston 12 to move downward in the piston cylinder 9.

[0029] It should be noted that an exhaust component is provided in the piston cylinder 9 for extracting the air in the suction cup 10 to form a vacuum negative pressure environment when tightening the bolt 19. The exhaust component includes a piston 12. The piston 12 is arranged inside the piston cylinder 9 and is slidably connected to the inner wall of the piston cylinder 9. A spring receiving groove 15 is provided on the inner bottom surface of the piston cylinder 9. A spring 16 is fixedly connected to the bottom surface of the piston 12. The bottom end of the spring 16 is fixedly connected to the bottom surface of the spring receiving groove 15. When the piston 12 moves downward in the piston cylinder 9, the elastic force of the spring 16 can be overcome, so that the spring 16 is compressed in the spring receiving groove 15.

[0030] Furthermore, the piston 12 divides the internal space of the piston cylinder 9 into an upper cavity and a lower cavity. An air guide hole 20 communicating with the lower cavity is provided on one side outer wall of the piston cylinder 9. When the piston 12 moves downward in the piston cylinder 9, the air in the lower cavity can be discharged through the air guide hole 20, thereby allowing the piston 12 to continue to move downward in the piston cylinder 9.

[0031] Furthermore, a gas passage 13 communicating with the upper cavity is provided on the piston 12, a hose 14 is fixedly connected to the bottom surface of the piston 12, the bottom end of the hose 14 is fixedly connected to the inner bottom surface of the piston cylinder 9, a through hole 11 communicating with the inner side of the suction cup 10 is provided on the top surface of the suction cup 10, the top end of the hose 14 is communicated with the gas passage 13, the bottom end of the hose 14 is communicated with the through hole 11, and the piston 12 moves downward in the piston cylinder 9, so that the air inside the suction cup 10 can be sucked into the upper cavity through the through hole 11, the hose 14 and the gas passage 13, thereby maintaining a vacuum negative pressure environment inside the suction cup 10.

[0032] The working principle and use process of the present invention are as follows: according to different fixing conditions, a suitable number of suction cups 10 can be selected for use, and the more suction cups 10 there are, the more firmly the charging pile base 1 is fixed;

[0033] When in use, place the required number of suction cups 10 at the positions corresponding to the groove 5 on the bottom surface of the charging pile base 1, and slide the piston cylinder 9 and the limiting plate 18 into the groove 5 and the limiting groove 6 respectively, so that the top surface of the piston cylinder 9 contacts the top surface of the groove 5. At this time, the first bolt hole 4 and the second bolt hole 17 correspond to each other, and then screw the bolt 19 into the first bolt hole 4. As the bolt 19 rotates, the bolt 19 passes through the first bolt hole 4 and the second bolt hole 17 in turn to connect the piston cylinder 9 to the charging pile base 1, and make the bottom end of the bolt 19 abut against the top surface of the piston 12. The state at this time is as follows: Figure 6 As shown;

[0034] Then continue to turn the bolt 19 to push the piston 12 downward. At this time, the air in the lower cavity is discharged from the air guide hole 20, so that the piston 12 can continue to move downward in the piston cylinder 9, and the air in the suction cup 10 will be sucked into the upper cavity at the top of the piston 12 through the through hole 11, the hose 14, and the gas channel 13. When the piston 12 drops to a certain position, the air in the suction cup 10 is sucked out, and at the same time, the hose 14 gradually bends as the piston 12 drops and is finally flattened by the piston 12 at the bottom end of the piston cylinder 9. At this time, the hose 14 is no longer connected to the through hole 11 and the gas channel 13, and plays a blocking role. At this time, the interior of the suction cup 10 is a vacuum environment and is firmly adsorbed on the ground. At the same time, the bolt 19 completes the fixed connection and installation of the piston cylinder 9 and the charging pile base 1;

[0035] When the suction cup 10 is completely adsorbed on the ground, the height of the suction cup 10 will become lower, and at this time the support leg 2 will contact the ground to play a supporting role, and then the charging pile 7 is placed on the charging pile base 1, and the external fixing screws are passed through the fixing piece 8 and fixed in the fixing hole 3 to complete the installation of the charging pile 7;

[0036] If the position of the charging pile 7 needs to be disassembled or changed, remove the charging pile 7 from the charging pile base 1, and then rotate the bolt 19 in the opposite direction to move it upward. At this time, the piston 12 will move upward under the elastic action of the spring 16, so that the external air can be replenished into the lower cavity through the air guide hole 20, and the hose 14 is no longer squeezed by the piston 12 and is reconnected with the through hole 11 and the gas channel 13. At the same time, the air in the upper cavity will enter the suction cup 10 through the gas channel 13, the hose 14, and the through hole 11 due to the squeezing of the piston 12. At this time, the interior of the suction cup 10 is no longer a vacuum environment, so it can be easily removed from the ground, and the charging pile base 1 can be removed from the piston cylinder 9 at the same time.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
