Description

Technical Field

[0001] The present invention belongs to the technical field related to new energy vehicle charging piles, and more specifically, particularly relates to a new energy vehicle charging pile based on a safety protection mechanism. Background Art

[0002] New energy vehicles refer to all other energy vehicles except gasoline and diesel engines. They include fuel cell vehicles, hybrid vehicles, hydrogen-powered vehicles and solar-powered vehicles, etc., which have relatively low exhaust emissions. The function of new energy vehicle charging piles is similar to that of gas pumps in gas stations, and can be fixed on the ground or wall. People generally install new energy vehicle charging piles outdoors, which is less safe. If new energy vehicle charging piles are installed outdoors, they will be exposed to wind, sun and rain, which will shorten the service life of the new energy vehicle charging piles. However, the new energy vehicle charging piles in the prior art have the following defects: In the prior art, when using new energy vehicles, it is essential to use charging piles for charging. However, since charging piles are mostly public facilities and protection measures are not in place, when the new energy vehicle is reversing to charge, it may accidentally squeeze or collide with the charging pile, causing damage to the charging pile, shortening the service life of the charging pile, and also causing damage to the rear of the new energy vehicle during the squeezing and collision process; 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 caused by the collision, which easily leads to collision damage of the charging pile and shortens the service life of the charging pile; In the prior art, when a new energy vehicle charging pile encounters a collision with a new energy vehicle, due to the lack of a supporting structure for the charging pile, the charging pile may tilt or the fixings between the charging pile and the ground may become loose, or even the charging pile may topple over, thus affecting the use of the charging pile.

Through the arrangement of a third movable plate, a rotating plate, a second buffer, and a V-shaped groove, the two rotating plates rotate to drive the two second buffers to rotate. The two second buffers rotate to squeeze and contact with the upper and lower side wall slopes of the V-shaped groove. Through the V-shaped groove side wall and the second buffer slope contact, the anti-collision plate is further subjected to the impact force in the horizontal direction for force division, which is divided into horizontal force and vertical force, further reducing the impact force in the horizontal direction of the anti-collision plate and transmitting it to the horizontal impact force on the first movable plate, which is conducive to reducing the impact force generated by the collision. Then, through the rotation of the two second buffers and the squeezing and contacting with the upper and lower side wall slopes of the V-shaped groove, the vertical force is divided into two vertical forces in opposite directions, and the two vertical forces offset each other, greatly reducing the impact force in the horizontal direction of the anti-collision plate and transmitting it to the horizontal impact force on the first movable plate, so as to offset the impact force generated by the anti-collision plate through the first elastic member, the first compression spring, and the second compression spring.

[0034] Preferably, see Attachment Figure 3 , Attachment Fig. 9Two second sliders 54 are fixedly provided on both sides of each slide plate 15, each second slider 54 slides in the side wall of the shell 18, and a first compression spring 55 is connected between one side of each second slider 54 and the side wall of the shell 18. Two third sliders 56 are fixedly provided on both sides of each first movable plate 20, each third slider 56 slides in the side wall of the shell 18, and a second compression spring 57 is connected between one side of each third slider 56 and the side wall of the shell 18.

[0035] Preferably, see Attachment Figure 1 To Attachment Figure 2 A plurality of heat dissipation openings 12 are provided on both side walls of the protective shell 10 .

[0036] Specific use of the present invention: When the safety protection mechanism of the protective shell 10 is squeezed and collided by the car, first, the car continues to squeeze the anti-collision pad 14, and the movement of the anti-collision pad 14 drives the anti-collision plate 13 and the two slides 15 to move. The movement of the slide 15 drives the two second sliders 54 to slide in the two side walls of the shell 18. The sliding of the two second sliders 54 compresses the two first compression springs 55. The compression of the two first compression springs 55 generates elastic force to buffer the anti-collision plate 13.

[0037] At the same time, the movement of the slide plate 15 drives the two fixed plates 16 to move, and the two fixed plates 16 contact the two first buffers 22 respectively; and the movement of the slide plate 15 makes the upper and lower side walls of the V-shaped groove 17 contact the two second buffers 26 respectively. The movement of the slide plate 15 drives the third movable plate 23 and the first movable plate 20 to move, and the movement of the first movable plate 20 squeezes and deforms the first elastic member 19, and the squeezing and deformation of the first elastic member 19 buffers the anti-collision plate 13. Among them, the movement of the first movable plate 20 drives the two side walls of the two third sliders 56 to slide, and the sliding of the two third sliders 56 compresses the two second compression springs 57, and the compression of the two second compression springs 57 generates elastic force to buffer the anti-collision plate 13.

[0038] Next, the three horizontal surfaces of the first elastic member 19 are limited by the three side walls of the housing 18 and cooperate with the movement of the first movable plate 20 to squeeze and deform the first elastic member 19, so that the first elastic member 19 is deformed up and down. The deformation of the first elastic member 19 pushes the two second slide plates 40 away from each other, and the two second slide plates 40 move away from each other, driving the two second push rods 41 and the pressure plate 42 away from each other. Through the sliding contact between one end of the pressure plate 42 and the inclined surface of one end of the second push rod 43, the two pressure plates 42 move away from each other to guide and squeeze the two second push rods 43 respectively, so that the two second push rods 43 move. The movement of the two second push rods 43 drives the movement of the two guide blocks 46, and through the sliding contact between one side of the second movable plate 21 and the inclined surface of one side of the guide block 46, the two guide blocks 46 move to guide and squeeze the two second movable plates 21 respectively, so that the two second movable plates 21 approach each other. The approach of the two second movable plates 21 drives the two first buffer members 22 to approach each other, and the two first buffer members 22 approach each other and squeeze the two fixed plates 16 on the inclined surface. The fixed plate 16 is in contact with the inclined surface of the first buffer member 22 so as to divide the impact force in the horizontal direction on the anti-collision plate 13 into horizontal force and vertical force. The two first buffer members 22 are in contact with the inclined surfaces of the two fixed plates 16 respectively, generating two vertical forces in opposite directions up and down, so as to make the two vertical forces offset each other. The horizontal force is transmitted to the first movable plate 20. At this time, the horizontal force is less than the impact force on the anti-collision plate 13. Thereby reducing the impact force in the horizontal direction of the anti-collision plate 13 transmitted to the horizontal impact force on the first movable plate 20, which is conducive to reducing the impact force generated by the collision and avoiding damage to the charging pile body 11. Among them, the movement of the two second push rods 43 drives the movement of the two third slide plates 44, and the movement of the two third slide plates 44 compresses the two third springs 45 to generate elastic force. Under the elastic force of the two third springs 45, the two third slide plates 44 and the second push rod 43 can be moved and reset.

[0039] At the same time, the two second slide plates 40 move away from each other to squeeze and deform the two second elastic members 47 respectively, 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 slide bar 50 to move downward, and the slide bar 50 moves downward to drive the support plate 51 and the wear-resistant plate 52 to move downward. The wear-resistant plate 52 moves downward and contacts with the ground frictionally, so that the fixed seat 49, the slide bar 50, the support plate 51, and the wear-resistant plate 52 can be used to support the protective shell 10 to prevent the protective shell 10 from tipping over. Among them, the slide bar 50 slides to stretch the fourth spring 53 to generate elastic force, and under the elastic force of the fourth spring 53, the slide bar 50 can be moved upward to reset.

[0040] Then, the two second movable plates 21 approach each other, driving the two first sliders 27 and the first push rods 34 to approach each other, and the two first push rods 34 approach each other, driving the two first piston plates 33 to approach each other. The two first piston plates 33 approach each other, squeezing the solution in the first hydraulic chamber 30 through the first connecting channel 32 into the second hydraulic chamber 31, and the solution in the second hydraulic chamber 31 pushes the two second piston plates 35 away from each other. The two second piston plates 35 move away from each other, driving the two first push rods 36 and the rubber blocks 37 to move away from each other, and the two rubber blocks 37 move away from each other, driving the two rotating plates 25 to rotate away from each other. The two rotating plates 25 rotate to drive the two second buffers 26 to rotate. The two second buffers 26 rotate to squeeze and contact with the upper and lower side wall slopes of the V-shaped groove 17. The side walls of the V-shaped groove 17 are in contact with the second buffers 26 slopes, and the impact force in the horizontal direction is further divided into horizontal force and vertical force, which further reduces the impact force in the horizontal direction of the impact plate 13 transmitted to the first movable plate 20, which is conducive to reducing the impact force generated by the collision. The two second buffers 26 rotate to squeeze and contact with the upper and lower side wall slopes of the V-shaped groove 17, so that the vertical force is divided into two vertical forces in opposite directions, and the two vertical forces offset each other, greatly reducing the impact force in the horizontal direction of the impact plate 13 transmitted to the first movable plate 20, so that the impact force generated by the impact plate 13 is offset by the first elastic member 19, the first compression spring 55, and the second compression spring 57. The two first sliders 27 approach each other and compress the two first springs 29 to generate elastic force, so that the two first sliders 27 can be reset away from each other under the elastic force of the two first springs 29. The two second piston plates 35 move away from each other and compress the two second springs 38 to generate elastic force, so that the two second piston plates 35 can be reset away from each other under the elastic force of the two second springs 38.

[0041] Finally, the material of the anti-collision pad 14 is impact-resistant buffer rubber. The anti-collision pad 14 can prevent the anti-collision plate 13 from scratching the surface of the car, thereby reducing the degree of damage to the surface of the car.

[0042] The present invention provides a new energy vehicle charging pile based on a safety protection mechanism. Through the arrangement of a second movable plate 21, a first buffer member 22, a fixed plate 16, and a guide block 46, the two second movable plates 21 approach each other to drive the two first buffer members 22 to approach each other, and the two first buffer members 22 approach each other to perform oblique extrusion with the two fixed plates 16 respectively; the fixed plate 16 is in oblique contact with the first buffer member 22 so as to facilitate the force division of the horizontal impact force received by the anti-collision plate 13, which is divided into horizontal force and vertical force; the horizontal force is transmitted to the first movable plate 20, thereby reducing the horizontal impact force of the anti-collision plate 13 and transmitting the horizontal impact force 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. The two first buffer members 22 are respectively in contact with the inclined surfaces of the two fixing plates 16 to generate two vertical forces in opposite directions. The two vertical forces offset each other, thereby reducing the impact force on the safety protection mechanism, which is beneficial to quickly reduce the impact force and avoid the protective shell 10 from tilting.

[0043] A new energy vehicle charging pile based on a safety protection mechanism of the present invention, through the arrangement of a third movable plate 23, a rotating plate 25, a second buffer member 26, and a V-shaped groove 17, the two rotating plates 25 rotate to drive the two second buffer members 26 to rotate, and the two second buffer members 26 rotate to squeeze and contact with the upper and lower side wall inclined surfaces of the V-shaped groove 17, and contact with the inclined surfaces of the second buffer members 26 through the side walls of the V-shaped groove 17, so that the impact force of the anti-collision plate 13 in the horizontal direction is further divided into horizontal force and vertical force, further reducing the horizontal impact force of the anti-collision plate 13 and transmitting it to the horizontal impact force on the first movable plate 20, which is beneficial to reduce the impact force caused by the collision. The two second buffer members 26 are then rotated to squeeze and contact the upper and lower side wall slopes of the V-shaped groove 17, so that the vertical force is divided into two vertical forces in opposite directions. The two vertical forces offset each other, greatly reducing the horizontal impact force of the anti-collision plate 13 transmitted to the horizontal impact force on the first movable plate 20, so that the impact force generated by the anti-collision plate 13 can be offset by the first elastic member 19, the first compression spring 55, and the second compression spring 57.
