[0040] In order to further explain the technical scheme of the present application, the present application will be described in detail below through specific embodiments.

[0041] As Figures 1-9As shown, a cost-saving charging pile, including charging pile shell 1, buffer shell 2, support rod 3 and buffer mechanism 4, charging pile shell 1 is provided with charging assembly and charging gun, for charging new energy vehicles. Buffer shell 2 is provided on the front side of the charging pile shell 1, buffer shell 2 includes front baffle 21 and side slide plate 22 provided on both sides of front baffle 21, side slide plate 22 is provided with guide sliding block 221, the side of charging pile shell 1 is provided with horizontal slide rail 11, guide sliding block 221 is connected with slide rail 11. Guide sliding block 221 and slide rail 11 support buffer shell 2, while ensuring that buffer shell 2 can move smoothly forward and backward. One end of support rod 3 is installed on the inner side wall of front baffle 21 and the other end of support rod 3 extends into charging pile shell 1 and is connected slidingly. Support rod 3 is mainly arranged at four corner parts of front baffle 21, support rod 3 plays a further supporting and guiding role for buffer shell 2. The front side of charging pile shell 1 is provided with mounting bracket 12, buffer mechanism 4 includes mounting rod 41, first adjusting block 42, second adjusting block 43, buffer top rod 44 and tension spring 45, mounting rod 41 is horizontally arranged at the center part of mounting bracket 12, first adjusting block 42 and second adjusting block 43 are arranged on mounting rod 41, buffer top rod 44 is evenly arranged on first adjusting block 42, specifically, buffer top rod 44 is provided with four and arranged in matrix around the axis of mounting rod 41. One end of buffer top rod 44 is rotatably connected with first adjusting block 42, the other end of buffer top rod 44 extends out of mounting bracket 12 and is provided with guide wheel 46, guide wheel 46 is rotatably connected with front baffle 21, tension spring 45 is arranged on second adjusting block 43, and the end of tension spring 45 is connected with the side wall of buffer top rod 44.

[0042] After the above structure, when the front baffle 21 is impacted by the tail of the car and moves backward, the front end of the buffer top rod 44 is driven by the front baffle 21 to swing backward, and the buffer top rod 44 exerts a forward pulling force on the buffer top rod 44 in the process of swinging, so that the front end of the buffer top rod 44 can exert a forward abutting force on the front baffle 21, thereby achieving the effect of buffering. Thus, the direct impact of the car on the charging pile shell 1 is avoided, the damage and maintenance frequency of the charging pile are greatly reduced, and the maintenance and operating costs are greatly reduced.

[0043] In the embodiment, in order to adjust the buffering force of the buffering mechanism 4, the buffering top rod 44 is arc-shaped, the mounting rod 41 is provided with a threaded section, the threaded section is provided with a locking nut 411 connected by screwing, and the first adjusting block 42 and the second adjusting block 43 are sleeved on the threaded section and fixed by the locking nut 411. After the above structure is adopted, the first adjusting block 42 and the second adjusting block 43 can adjust the front and back distance and the interval. Since the support rod 3 limits the position of the front baffle 21, when the first adjusting block 42 is set further backward, the front end of the buffering top rod 44 is closer to the middle axis of the connecting rod, and it is more difficult for the front baffle 21 to abut against the front end of the buffering top rod 44 outward. At this time, the abutting buffering force generated by the buffering top rod 44 is greater. Moreover, the greater the distance between the first adjusting block 42 and the second adjusting block, the greater the tension of the tension spring 45, and thus the greater the abutting buffering force generated by the buffering top rod 44. The above structure makes the buffering mechanism 4 have more flexible adjustment function, and the adjustment structure is simple and convenient to operate.

[0044] Preferably, the buffering spring 47 is arranged between the front baffle 21 and the mounting frame 12. The buffering spring 47 can further buffer and enhance the buffering capacity of the buffering shell 2.

[0045] In the embodiment, the inside of the charging pile shell 1 is provided with a limiting sleeve 13, the end of the support rod 3 penetrates through the limiting sleeve 13, the end of the support rod 3 is provided with an abutting block 31 connected by screwing, the abutting block 31 abuts against the limiting sleeve 13. The abutting block 31 is provided with a buffering block 32, the buffering block 32 is provided with a through hole 321, the through hole 321 is provided with an arc-shaped block 33, the limiting sleeve 13 is provided with an elastic rope 34, the two ends of the elastic rope 34 are connected to the limiting sleeve 13, and the middle part of the elastic rope 34 penetrates through the through hole 321 and abuts against the arc-shaped block 33. After the above structure is adopted, the abutting block 31 can adjust the mounting process, thereby limiting the support rod 3 and the buffering shell 2 together with the limiting sleeve 13, and avoiding the support rod 3 from being pulled out of the limiting sleeve 13. During normal use, the elastic rope 34 applies a forward abutting force to the arc-shaped block 33, so that the abutting block 31 and the limiting sleeve 13 abut against each other to limit and fix. When the front baffle 21 is impacted, the buffering block 32 moves backward to cause the elastic rope 34 to deform, at this time, the abutting force of the elastic rope 34 to the arc-shaped block 33 is increased, thereby supporting and buffering the support rod 3, having a secondary buffering effect on the buffering shell 2, further enhancing the buffering force of the buffering mechanism 4, and ensuring that the charging pile shell 1 is not damaged by impact.

[0046] Preferably, the inner side wall of the front baffle 21 is provided with a guide groove 211 for the guide wheel 46 to slide. After the above structure is adopted, the guide wheel 46 can roll more stably, and the buffering top rod 44 can be prevented from swinging left and right, so that the overall structure of the buffering mechanism 4 is more stable.

[0047] More preferably, the front baffle 21 is provided with a buffer air cushion 212. The buffer air cushion 212 can play a buffering effect at the first time when the rear of the automobile hits the front baffle 21, greatly reducing the impact degree.

The end of the pressure rod 15 abuts against the pressure sensor 14. After the above structure is adopted, when the front baffle 21 is hit and the pressure rod 15 is driven to move backward, the pressure sensor 14 senses the pressure change and controls the warning light to light up through the control system, and the buzzer emits an alarm sound to warn the driver, preventing the driver from continuing to back up and increasing the impact degree.

At the same time, the second output shaft 532 drives the second blades 521 to rotate through the transmission mechanism.

Then the cooling liquid flows into the annular flow channel 5423 through the liquid outlet hole 5213, and is discharged through the liquid outlet pipe 5422, the discharged cooling liquid can be treated by the filtering device and the cooling device 5 and then flows back into the water tank, so that the cooling liquid is recycled. And sealing components such as sealing rings are arranged on the connecting surface of the pressing plate 542 and the driving sleeve 52, so as to avoid leakage of the liquid in the annular flow channel 5423.

[0053] More preferably, the driving sleeve 52 is provided with an embedding groove at the lower end of the second blade 521, and a cooling fin 57 is embedded in the embedding groove.

[0054] In the embodiment, since the charging pile is mostly arranged outdoors, a large amount of dust and sundries will often adhere to the second blade 521 after long-time work, which will cause the second blade 521 to blow the dust and sundries into the charging pile shell 2 when working, causing the charging assembly to have an electrostatic phenomenon.
