Description

TECHNICAL FIELD

[0002] New energy vehicles refer to all other energy vehicles except gasoline and diesel engines. They include fuel cell vehicles, hybrid electric vehicles, hydrogen energy power vehicles and solar vehicles, and have low exhaust emission. The new energy vehicle charging pile has a function similar to the fuel dispenser in the gas station and can be fixed to the ground or wall. People generally install new energy vehicle charging piles outdoors, which has low safety. If the new energy vehicle charging pile is installed outdoors and is blown by the wind, exposed to sunlight and drenched in rain, the service life of the new energy vehicle charging pile will be shortened. However, the new energy vehicle charging pile in the prior art has the following defects:

[0003] In the prior art, it is necessary to use a charging pile for charging during the use of a new energy vehicle. However, since the charging pile is mostly a public facility, and the protection measures are not in place, the charging pile may be damaged due to accidental extrusion or collision when the new energy vehicle reverses to prepare for charging, which shortens the service life of the charging pile. At the same time, the tail of the new energy vehicle may also be damaged during the extrusion and collision process.

[0004] In the prior art, the buffering effect of the safety protection mechanism in the new energy vehicle charging pile is limited, and it is difficult to reduce the impact force generated by the collision, which easily leads to the collision damage of the charging pile and shortens the service life of the charging pile.

[0005] In the prior art, when the new energy vehicle charging pile encounters a new energy vehicle collision, the lack of a support structure for the charging pile leads to the tilting of the charging pile or the loosening of the charging pile and the ground fixing member, or even the tilting of the charging pile, which affects the use of the charging pile.

[0051] Preferably, referring to the accompanying drawings Figure 1 to the accompanying drawings Figure 2 The two side walls of the protective shell 10 are each provided with a plurality of heat dissipation openings 12.

[0052] The specific use method of the present application is as follows:

[0053] When the safety protection mechanism of the protective shell 10 is subjected to extrusion collision of the automobile, first, the automobile continuously extrudes the crash pad 14, the crash pad 14 moves to drive the crash plate 13 and the two sliding plates 15 to move, the sliding plates 15 move to drive the two second sliding blocks 54 to slide in the two side walls of the shell 18, the two second sliding blocks 54 slide to compress the two first compression springs 55, the two first compression springs 55 are compressed to generate elastic force to buffer the crash plate 13.

[0054] At the same time, the movement of the sliding plates 15 drives the movement of the two fixed plates 16, the two fixed plates 16 are in contact with the two first buffer members 22 respectively; and the movement of the sliding plates 15 makes the upper and lower side walls of the V-shaped groove 17 in contact with the two second buffer members 26 respectively. The movement of the sliding plates 15 pushes the third movable plate 23 and the first movable plate 20 to move, the movement of the first movable plate 20 extrudes and deforms the first elastic member 19, and the extrusion and deformation of the first elastic member 19 buffers the crash plate 13. Among them, the movement of the first movable plate 20 drives the two side walls of the two third sliding blocks 56 to slide, the two third sliding blocks 56 slide to compress the two second compression springs 57, the two second compression springs 57 are compressed to generate elastic force to buffer the crash plate 13.

[0055] Then, the three horizontal faces of the first elastic member 19 are limited by the three side walls of the shell 18 to move the first movable plate 20 to extrude and deform the first elastic member 19, so that the first elastic member 19 is deformed up and down. The first elastic member 19 is deformed to push the two second sliding plates 40 away from each other, and the two second sliding plates 40 away from each other drive the two second push rods 41 and the pressing plate 42 away from each other. Through the inclined surface sliding contact between one end of the pressing plate 42 and one end of the second top rod 43, the two pressing plates 42 are away from each other and are extruded to guide the two second top rods 43, so that the two second top rods 43 move. The movement of the two second top rods 43 drives the two guide blocks 46 to move, and through the inclined surface sliding contact between one side of the second movable plate 21 and one side of the guide block 46, the two guide blocks 46 move to guide and extrude the two second movable plates 21 respectively, so that the two second movable plates 21 move close to each other. The two second movable plates 21 move close to each other to drive the two first buffer members 22 to move close to each other, and the two first buffer members 22 move close to each other to be inclinedly extruded by the two fixed plates 16 respectively. Through the inclined surface contact between the fixed plate 16 and the first buffer member 22, the impact force in the horizontal direction is applied to the anti-collision plate 13 to be divided into horizontal force and vertical force. Through the inclined surface contact between the two first buffer members 22 and the two fixed plates 16 respectively, two vertical forces in opposite directions are generated to cancel each other out. The horizontal force is transmitted to the first movable plate 20, and at this time, the horizontal force is smaller than the impact force of the anti-collision plate 13. Thus, the horizontal impact force of the anti-collision plate 13 is transmitted to the first movable plate 20, which is beneficial to reduce the impact force generated by the collision and avoid damage to the charging pile body 11. Among them, the movement of the two second top rods 43 drives the movement of the two third sliding plates 44, and the movement of the two third sliding plates 44 extrudes the two third springs 45 to generate elastic force. Under the action of the elastic force of the two third springs 45, the two third sliding plates 44 and the second top rod 43 can be reset.

[0056] At the same time, the two second sliding plates 40 are away from each other to extrude and deform the two second elastic members 47, and the solution in the two second elastic members 47 enters the fixed seat 49 through the second connecting channel 48. The solution in the fixed seat 49 pushes the sliding rod 50 to move obliquely downward, and the sliding rod 50 moves obliquely downward to drive the support plate 51 and the wear-resistant plate 52 to move downward. The wear-resistant plate 52 moves downward and frictionally contacts the ground to support the protective shell 10 by using the fixed seat 49, the sliding rod 50, the support plate 51 and the wear-resistant plate 52, so as to avoid the protective shell 10 from falling. Among them, the sliding rod 50 slides to stretch the fourth spring 53 to generate elastic force, and under the action of the elastic force of the fourth spring 53, the sliding rod 50 can be reset obliquely upward.

[0057] Then, the two second movable plates 21 are close to each other, driving the two first sliders 27 and the first push rods 34 to be close to each other, and the two first push rods 34 are close to each other, driving the two first piston plates 33 to be close to each other. The two first piston plates 33 are close to each other, extruding the solution in the first hydraulic cavity 30 through the first connecting channel 32 into the second hydraulic cavity 31, and the solution in the second hydraulic cavity 31 drives the two second piston plates 35 to be away from each other. The two second piston plates 35 are away from each other, driving the two first top rods 36 and the rubber blocks 37 to be away from each other, and the two rubber blocks 37 are away from each other, driving the two rotating plates 25 to be away from each other and rotate. The two rotating plates 25 rotate, driving the two second buffers 26 to rotate, and the two second buffers 26 rotate and extrude the upper and lower sidewall inclined surfaces of the V-shaped groove 17, and the V-shaped groove 17 sidewall and the second buffer 26 inclined surface are in contact, further preventing the impact force of the impact plate 13 in the horizontal direction from being subjected to force action, which is divided into horizontal force and vertical force, further reducing the horizontal impact force of the impact plate 13 transmitted to the horizontal impact force of the first movable plate 20, and is beneficial to reduce the impact force generated by the collision. The two second buffers 26 rotate and extrude the upper and lower sidewall inclined surfaces of the V-shaped groove 17, so as to divide the vertical force into two vertical forces in opposite directions, the two vertical forces cancel each other out, greatly reducing the horizontal impact force of the impact plate 13 transmitted to the horizontal impact force of the first movable plate 20, so as to offset the impact force generated by the impact plate 13 through the first elastic element 19, the first compression spring 55 and the second compression spring 57. Among them, the two first sliders 27 are close to each other, respectively compressing the two first springs 29 to generate elastic force, so as to make the two first sliders 27 away from each other under the action of the elastic force of the two first springs 29. The two second piston plates 35 are away from each other, respectively compressing the two second springs 38 to generate elastic force, and under the action of the elastic force of the two second springs 38, the two second piston plates 35 can be reset.

[0058] Finally, the material of the anti-collision pad 14 is impact-resistant buffer rubber, which can avoid scratching the surface of the car by the impact plate 13 and reduce the damage degree of the surface of the car.

[0059] The new energy automobile charging pile based on the safety protection mechanism has the advantages that: the second movable plates 21 are arranged to drive the two first buffer members 22 to approach each other, the two first buffer members 22 approach each other and are in inclined surface extrusion with the two fixed plates 16 respectively, the fixed plates 16 and the first buffer members 22 are in inclined surface contact, so that the horizontal impact force on the anti-collision plate 13 is subjected to force action, and the horizontal force and the vertical force are formed, the horizontal force is transmitted to the first movable plate 20, thereby reducing the horizontal impact force of the anti-collision plate 13 transmitted to the first movable plate 20, the impact force generated by the collision is reduced, and the charging pile body 11 is prevented from being damaged.
