Description

Technical Field

[0001] The utility model relates to the technical field of charging pile protection devices, in particular to a new energy charging pile protection device. Background Art

[0002] The function of new energy charging piles is similar to that of gas pumps. They can be fixed on the ground or wall and installed in public buildings (public buildings, shopping malls, public parking lots, highway service area charging stations, etc.) and residential parking lots or charging stations. They can charge various models of electric vehicles according to different voltage levels.

[0003] At present, the existing new energy outdoor charging piles have a relatively traditional and simple structural design, most of which lack protective structures and have poor protection when in use. Some drivers with poor driving skills are prone to collision with the charging piles when driving backwards and approaching the charging piles, which can cause damage to the charging piles, increase maintenance costs, and cause the charging station to be temporarily unusable, resulting in large economic losses. Utility Model Content

[0004] The technical problem to be solved by the utility model is: in order to overcome the above-mentioned problems, a new energy charging pile protection device is provided, which solves the above-mentioned problems.

[0005] The utility model solves the technical problem by adopting the following technical solutions:

[0006] A new energy charging pile protection device comprises two guardrail frames fixedly arranged on the sides of a fast charging pile, a viscous damping cylinder and a linear sliding cylinder coaxial with the viscous damping cylinder are welded and fixed on the guardrail frame, a support shaft is provided through the linear sliding cylinder and inserted in the viscous damping cylinder, and a damping piston with a damping hole is fixedly arranged at the tail end of the support shaft, and a viscous damping liquid is arranged in the viscous damping cylinder, an auxiliary spring is sleeved on the outer surface of the support shaft, and a push plate frame is fixed between the support shafts, when the push plate frame pushes the support shaft backward after being impacted by a vehicle, at this time, the damping piston presses against the viscous damping liquid, so that the viscous damping liquid passes through the damping hole under pressure, in this process, kinetic energy is converted into heat energy, realizing kinetic energy consumption, the auxiliary spring also plays a certain buffering role, and the guardrail frame plays a supporting role, when the vehicle moves away, the support shaft is pushed forward under the elastic deformation of the auxiliary spring so that the damping piston is reset in an orderly manner, thereby realizing an automatic secondary preparation state, and being able to cope with the next impact even without anyone managing it.

[0007] Preferably, an air cavity piston is sealed and slidably provided in the viscous damping cylinder, and a pressurized air-filled cavity is provided behind the air cavity piston, thus forming a secondary buffer cavity. When the supporting axle is impacted and the damping piston retreats rapidly, the oil cavity pressure behind the damping piston will suddenly increase. At this time, the air cavity piston can adaptively buffer by compressing the pressurized air-filled cavity, thereby quickly consuming the impact kinetic energy.

[0008] Preferably, it also includes a plurality of ground piles, at the upper ends of which a ground pile connector is welded and fixed, the ground piles are cast and fixed below the ground, the ground pile connector extends out of the ground surface, and coaxial plug shafts inserted into the ground pile connectors are fixed at the front and rear ends of the guardrail frame, and a flange is also fixed at the end of the guardrail frame, and the flange is fixed to the ground pile connector by bolts, which facilitates construction and installation.

[0009] Preferably, a replaceable buffer sponge pad is embedded and fixed on the front end surface of the push plate frame. The thickness and hardness of the buffer sponge pad can be selected according to needs. The force component of the buffer sponge pad can reduce damage to the vehicle and reduce stress concentration at the impact point, thereby avoiding breakage of the push plate frame.

[0010] Preferably, reinforcing ribs are welded and fixed on the back side of the push plate frame, which effectively enhances the structural strength of the push plate frame.

[0011] The advantages and positive effects of the utility model are:

[0012] The guardrail frame and ground stakes are installed separately, making installation more convenient and easy to replace.

[0013] A two-stage superimposed buffer is formed by viscous damping fluid and a pressurized air chamber. During the retreat of the support shaft, the impact kinetic energy is converted into heat energy to achieve a good effect of absorbing impact. When the vehicle is moved away, the support shaft is reset in an orderly manner, which is convenient for dealing with the next impact hazard.

[0014] The concentrated stress on the contact surface between the device and the vehicle is effectively reduced by the replaceable buffer sponge pad. Since the buffer sponge pad has a certain deformation effect, it will actively adapt to the shape of the outside of the vehicle after contacting the vehicle to increase the effective contact area and avoid stress concentration. It can effectively reduce the deformation and damage degree of the impact point of the vehicle, and is easy to replace, thereby reducing the cost of use. BRIEF DESCRIPTION OF THE DRAWINGS

The following is a further detailed description of the embodiments of the utility model in conjunction with the accompanying drawings:

[0021] like Figure 1-2 As shown, a new energy charging pile protection device described in the utility model includes two guardrail frames 12 fixedly arranged on the sides of a fast charging pile 18, a viscous damping cylinder 13 and a linear sliding cylinder 14 coaxial with the viscous damping cylinder 13 are welded and fixed on the guardrail frame 12, a support shaft 15 is provided passing through the linear sliding cylinder 14 and inserted in the viscous damping cylinder 13, and a damping piston 24 with a damping hole 25 is fixed at the tail end of the support shaft 15, and a viscous damping liquid 21 is provided in the viscous damping cylinder 13, an auxiliary spring 19 is provided outside the support shaft 15, and a spring 21 is fixed between the support shaft 15. A push plate frame 16 is provided. When the push plate frame 16 is impacted by a vehicle, it pushes the support shaft 15 backward. At this time, the damping piston 24 presses against the viscous damping fluid 21, so that the viscous damping fluid 21 passes through the damping hole 25 under pressure. In this process, kinetic energy is converted into heat energy to realize kinetic energy consumption. The auxiliary spring 19 also plays a certain buffering role. The guardrail frame 12 plays a supporting role. When the vehicle moves away, the support shaft 15 is pushed forward under the elastic deformation of the auxiliary spring 19, so that the damping piston 24 is reset in an orderly manner, thereby realizing an automatic secondary preparation state, and being able to cope with the next impact without anyone managing it.

[0022] Preferably, an air chamber piston 23 is sealed and slidably provided in the viscous damping cylinder 13, and a pressurized air-filled chamber 22 is provided behind the air chamber piston 23, so as to form a secondary buffer chamber. When the support shaft 15 is suddenly impacted and the damping piston 24 retreats rapidly, the oil chamber pressure behind the damping piston 24 will suddenly increase. At this time, the air chamber piston 23 can adaptively buffer by compressing the pressurized air-filled chamber 22, thereby quickly consuming the impact kinetic energy.

[0023] Preferably, it also includes a plurality of ground piles 10, at the upper end of which a ground pile connector 11 is welded and fixed, the ground pile 10 is cast and fixed below the ground, the ground pile connector 11 extends out of the ground surface, and a coaxial plug shaft 26 inserted into the ground pile connector 11 is fixed at the front and rear ends of the guardrail frame 12, and a flange 27 is also fixed at the end of the guardrail frame 12, and the flange 27 is fixed to the ground pile connector 11 by bolts, which facilitates construction and installation.

[0024] Preferably, a replaceable buffer sponge pad 17 is embedded and fixed on the front end surface of the push plate frame 16. The thickness and hardness of the buffer sponge pad 17 can be selected according to needs. The component force of the buffer sponge pad 17 can reduce damage to the vehicle and reduce stress concentration at the impact point, thereby avoiding breakage of the push plate frame 16.

[0025] Preferably, a reinforcing rib 20 is welded and fixed on the back side of the push plate frame 16 , which effectively enhances the structural strength of the push plate frame 16 .
