Description

Technical Field

[0001] The present invention relates to the technical field of parking lot charging piles, and in particular to a charging pile full-load performance testing system. Background Art

[0002] Underground parking lot charging piles refer to electric vehicle charging equipment installed in the underground space of an underground parking lot. This type of charging pile is usually installed on both sides of the parking space or in the corners of the parking area to meet the charging needs of electric vehicle owners. Since the charging piles are installed in the underground space, they will not occupy the space in the ground parking area, effectively saving parking resources.

[0003] Publication number CN214564707U retrieved discloses a charging pile, including a charging pile body and a mounting plate, the charging pile body is fixedly mounted on the side wall of the mounting plate, a charging line is arranged on the charging pile body, a protective frame is fixedly connected to the side wall at one end of the mounting plate, a rotating shaft is rotatably connected to the inner wall at one end of the protective frame, one end of the rotating shaft rotates and penetrates the side wall at one end of the protective frame, a winding roller is coaxially fixedly connected to the rotating shaft in the protective frame, through holes are connected on the top and the inner wall at one end of the protective frame, the charging line movably penetrates the two through holes, the charging line in the protective frame is wound on the winding roller, a limiting mechanism is arranged on the side wall at one end of the protective frame, the charging line slides through the limiting mechanism, and a connecting block is fixedly connected to the side wall at one end of the protective frame. The present invention can not only effectively limit and fix the charging line on the charging pile body, but also effectively protect the charging pile body.

[0004] This patented technology has the advantage of limiting the cable during use, but there are still some shortcomings during use. The charging pile body does not have an effective protective device. When improper parking causes a collision, the impact force directly acts on the charging pile body, causing the charging pile body to be easily damaged. For this reason, we propose a charging pile full load performance test system to solve the existing problems. Summary of the invention

[0005] The purpose of the present invention is to propose a charging pile full load performance test system in view of the problems existing in the background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a charging pile full-load performance test system, comprising an underground charging pile, a telescopic rod, a cylinder foundation groove and an installation frame, a rotating seat three is arranged at the lower end of the underground charging pile, a rubber seat is embedded and installed inside the front end of the underground charging pile, a mounting frame is arranged on one side of the rubber seat, and two equidistantly distributed springs are arranged at the rear end of the installation frame, a cylinder is arranged inside one side of the foundation groove, a rotating seat two is arranged at one end of the cylinder, a sealing ring is embedded and installed inside one end of the cylinder, the telescopic rod is slidably inserted inside the sealing ring, a rotating seat one is arranged at one end of the telescopic rod, a spring one is sleeved on the outer side of the cylinder and the telescopic rod, a piston is arranged at one end of the telescopic rod, and one-way valve one and one-way valve two are arranged inside the piston.

[0007] Preferably, both front and rear ends of the rotating seat 3 are connected to the inner wall of the foundation groove, and both front and rear ends of the rotating seat 2 are connected to the inner wall of the foundation groove. The rotating seat 2 provides rotation support for the lower end of the cylinder, and the cylinder can rotate when subjected to an impact force.

[0008] Preferably, one end of the spring 2 is provided with a mounting plate, and one end of the mounting plate is connected to the rubber seat. The spring mounting plate of the spring 2 is fixed on the rubber seat, and the spring 2 buffers the impact force to prevent the impact force from directly acting on the buried charging pile, and the rubber seat plays a damping role.

[0009] Preferably, the installation frame has rollers rotatably installed inside thereof and distributed equidistantly in the longitudinal direction, and one end of the rollers protrudes outside the installation frame. When a vehicle collides, it contacts the rollers, and the impact force is partially converted into rotational force to be unloaded, thereby reducing the damage to the installation frame caused by the impact.

[0010] Preferably, a mounting block is provided at one end of the underground charging pile, and the mounting block is rotatably mounted inside the rotating seat 1. The ground charging pile is rotatably mounted with the telescopic rod through the mounting block, and the elastic support of the spring 1 passes through the rotating parts at both ends, ensuring that the telescopic rod can effectively slide and reset inside the cylinder, and the reset telescopic rod supports the underground charging pile in a vertical shape, which is convenient for the use of the underground charging pile.

[0011] Preferably, the cylinder and the outer wall of the telescopic rod are both sleeved with a limit plate, and both ends of the spring one are connected to the limit plate. The limit plate fixes both ends of the spring one.

[0012] Preferably, the piston is slidably mounted inside the cylinder, the one-way valve 1 and the one-way valve 2 pass in opposite directions, and hydraulic oil is arranged inside the cylinder. When the hydraulic oil inside the cylinder is squeezed by the piston, it can only flow toward one of the one-way valves according to the squeezing direction, and when passing through a single one-way valve, the lower channel exerts resistance on the hydraulic oil, thereby forming damping on the spring 1.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention installs the lower end of the charging pile body in the foundation groove for underground installation. A buffer spring 2 is arranged at one end corresponding to the parking space, and a spring 1 buffer is arranged at the opposite end. Through three rotating parts, the underground charging pile realizes rotation with the rotating seat 3 as the axis, and cooperates with the damping medium inside the cylinder to slow down the movement of the piston when the piston impacts. The impacted underground charging pile rotates with the impact force, and the impact force is unloaded, reducing the damage to the charging pile. It has high installation performance and does not require a lifting device to lift the charging pile to the ground, thereby reducing maintenance costs.

[0015] 2. At the same time, when the impact piece is used to hit the underground charging pile, the spring 1 supports the telescopic rod to reset through its own elasticity. During the reset process, the damping medium inside the cylinder is squeezed by the piston and passes through the one-way valve in the passage. The narrow passage exerts a damping effect on the spring 1, and the underground charging pile slowly rotates and rises to achieve automatic and smooth reset. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figure 1-Figure 5As shown, a charging pile full-load performance test system proposed by the present invention comprises an underground charging pile 1, a telescopic rod 3, a cylinder 4 foundation groove 5 and an installation frame 17, a rotating seat 3 8 is arranged at the lower end of the underground charging pile 1, a cylinder 4 is arranged inside one side of the foundation groove 5, a rotating seat 2 7 is arranged at one end of the cylinder 4, a sealing ring 14 is embedded and installed inside one end of the cylinder 4, the telescopic rod 3 is slidably inserted into the sealing ring 14, a rotating seat 2 is arranged at one end of the telescopic rod 3, a spring 6 is sleeved on the outer sides of the cylinder 4 and the telescopic rod 3, a piston 11 is arranged at one end of the telescopic rod 3, and a movable A one-way valve 12 and a one-way valve 2 13 are arranged inside the plug 11, the piston 11 is slidably installed inside the cylinder 4, the one-way valve 12 and the one-way valve 2 13 pass in opposite directions, and hydraulic oil is arranged inside the cylinder 4, the front and rear ends of the rotating seat 3 8 are connected to the inner wall of the foundation groove 5, the front and rear ends of the rotating seat 2 7 are connected to the inner wall of the foundation groove 5, a mounting block 9 is arranged at one end of the underground charging pile 1, the mounting block 9 is rotatably installed inside the rotating seat 1 2, the outer walls of the cylinder 4 and the telescopic rod 3 are both sleeved with a limit plate 10, and the two ends of the spring 1 6 are connected to the limit plate 10.

[0024] The implementation steps based on Example 1 are as follows: the ground charging pile is rotatably installed inside the rotating seat through the mounting block 9, and is rotatably installed with the telescopic rod 3. The rotating seat 27 rotatably supports the lower end of the cylinder 4. The cylinder 4 can rotate when subjected to an impact force. During impact, the underground charging pile 1 rotates with the rotating seat 27 as the axis. During the process of the underground charging pile 1 being tilted, the spring 1 6 and the spring 2 19 buffer the impact force. When the hydraulic oil inside the cylinder 4 is squeezed by the piston 11, it can only flow toward one one-way valve according to the direction of squeezing. When passing through a single one-way valve, the lower channel exerts resistance on the hydraulic oil, forms damping on the spring 1 6, and removes the impact force.

The spring 2 19 and the spring mounting plate 16 are fixed on the rubber seat 15.
