The locking component 1 includes a first support 11 and a pin 12. A locking hole 111 penetrating both end faces is formed in the middle of the first support 11. Two relatively arranged avoidance grooves 112 are formed on the inner wall of the locking hole 111. The two pins 12 are respectively arranged telescopically in the corresponding avoidance grooves 112. In this embodiment, the axis line of the pin 12 is perpendicular to the axis line of the locking hole 111. The buckling component 2 includes a second support 21, a sliding rod 22, a buckle 23 and a guiding slider 24. The second support 21 is arranged opposite to the first support 11. One end of the sliding rod 22 is connected to the second support 21, and the other end extends towards the center of the locking hole 111 and is fixedly sleeved with the buckle 23 at its extending end. The guiding slider 24 is movably sleeved on the sliding rod 22, and a card slot 3 for the pin 12 to be inserted into is formed between the guiding slider 24 and the buckle 23 accordingly. One end of the guiding slider 24 abuts against the end face of the second support 21. In this embodiment, the outer peripheral surfaces of the buckle 23 and the guiding slider 24 are both inclined surfaces, so that the pin 12 can slide along the outer peripheral surfaces of the buckle 23 and the guiding slider 24 without being restricted.

[0029] During use, please refer to Figure 3-5 , by moving the second support 21 to the right towards the locking hole 111, and after the buckle 23 slides past the pin 12, the pin 12 that abuts against the card slot 3 after reset is used to limit the buckle 23 to complete the locking; please refer to Figure 5 , when unlocking the locking component 1 and the buckling component 2, only need to continue to move the second support 21 to the right towards the locking hole 111, and after the guiding slider 24 slides past the pin 12, move the second support 21 to the left or in the reverse direction, please refer to Figure 6-8 , the guiding slider 24 and the buckle 23 can respectively slide past the pin 12 through their inclined surfaces in sequence, so as to complete the unlocking, which has the advantages of fast and stable locking and unlocking.

[0030] Please refer to Figure 3-4 , the locking component 1 includes a first return spring 13. One end of the first return spring 13 is fixed on the groove wall of the avoidance groove 112, and the other end is connected to the end of the pin 12 extending into the avoidance groove 112. The end face of the pin 12 facing the center of the locking hole 111 is an arc surface.

[0031] The locking component 1 includes a limit screw 14 arranged in the avoidance groove 112. A limit groove 121 for the limit screw 14 to be inserted into is formed at the end of the pin 12 connected to the first return spring 13. The first return spring 13 is sleeved on the limit screw 14. The limit screw 14 plays a limiting role to ensure the stable telescopic movement of the pin 12. Please refer to Figure 5, during the process of the buckle 23 or the guiding slider 24 moving through the locking hole 111, when the pin 12 is pushed by the buckle 23 or the guiding slider 24, the pin 12 contracts into the avoiding groove 112 due to the force, and at this time, the first return spring 13 is compressed and the limit screw 14 is inserted into the limit groove 121; after the buckle 23 or the guiding slider 24 moves through the locking hole 111, or when the radius of contact between the pin 12 and the buckle 23 or the guiding slider 24 gradually becomes smaller, the pin 12 gradually extends into the locking hole 111 along the avoiding groove 112 under the elastic force of the first return spring 13.

[0032] Please refer to Figure 3-4 , one end of the buckle 23 facing the center of the locking hole 111 is bullet-shaped, and a groove 231 surrounding the outer circumference of the sliding rod 22 is formed on the end face of the buckle 23 facing the guiding slider 24. In this embodiment, the groove 231 is a tapered groove structure. The guiding slider 24 includes an abutting portion 241 and a guiding portion 242 connected to the abutting portion 241. The abutting portion 241 is a tapered structure adapted to the groove 231, and its radius gradually becomes smaller towards the end of the sliding rod 22. The guiding portion 242 is a tapered structure, and its radius gradually becomes smaller towards the second support 21. The slot 3 is formed between the abutting portion 241 and the end face of the buckle 23. In this embodiment, the connection between the abutting portion 241 and the guiding portion 242 is connected by a transition inclined surface.

[0033] Please refer to Figure 3-4 , the buckling component 2 includes a second return spring 25 sleeved on the sliding rod 22. One end of the second return spring 25 is connected to the inner wall of the groove 231 of the buckle 23, and the other end is connected to the abutting portion 241. In the non-loaded state, the second return spring 25 pushes the guiding slider 24 away to separate the guiding slider 24 from the buckle 23, so that a slot 3 can be formed between the abutting portion 241 and the end face of the buckle 23, facilitating the pin 12 to be snapped in for limiting.

[0034] Please refer to Figure 6 , during the unlocking process of the locking component 1 and the buckling component 2, when the guiding portion 242 slides past the pin 12, due to the clamping force of the pin 12 on the guiding portion 242, the entire guiding slider 24 moves along the end of the sliding rod 22, and further causes the abutting portion 241 to move along the sliding rod 22 and be embedded into the groove 231. At this time, the second return spring 25 is compressed, and the end face of the buckle 23 and the inner wall of the groove 231 are attached to the wall surface of the abutting portion 241, so that the abutting portion 241 forms a connection with the inclined surface outside the guiding portion 242, facilitating the guiding portion 242 and the buckle 23 to slide past the pin 12 in sequence when the buckling component 2 continues to move leftward. Please refer to Figure 7 , after the guiding portion 242 and the buckle 23 slide past the pin 12 in sequence, the guiding slider 24 moves and resets along the sliding rod 22 towards the second support 21 under the elastic force of the second return spring 25.

[0035] Please refer to Figure 5 . A buffer block 15 is provided on the end face of the first support 11 facing the second support 21. The middle part of the second support 21 protrudes towards the first support 11 to form a protrusion 211, and pressing parts 212 connected to the protrusion 211 are formed at both ends of the protrusion 211 correspondingly. One end of the sliding rod 22 is connected to the protrusion 211. When the locking component 1 and the buckling component 2 are unlocked, the second support 21 continues to move rightward towards the keyhole 111 until the buffer block 15 presses against the pressing part 212 correspondingly. The buffer block 15 plays a buffering role to prevent the second support 21 from moving excessively and causing a collision between the second support 21 and the first support 11.

[0036] The working principle of the locking device for the shared charging pile of the electric vehicle of the present utility model is as follows:

[0037] Please refer to Figure 3 . When the locking component 1 and the buckling component 2 are in an unlocked state, please refer to Figure 4 . When it is necessary to lock the locking component 1 and the buckling component 2, move the second support 21 rightward towards the keyhole 111. The pin 12 contracts into the avoidance groove 112 due to the pushing force of the buckle 23. After the buckle 23 slides past the pin 12, the pin 12 reset by the first return spring 13 abuts into the clamping groove 3 to limit the buckle 23. At this time, the buckle 23 cannot move leftward, thus completing the locking of the locking component 1 and the buckling component 2, with high stability and not easy to disengage.

[0038] When it is necessary to unlock the locking component 1 and the buckling component 2, please refer to Figure 5 . Move the second support 21 continuously rightward towards the keyhole 111. The abutting part 241 and the guiding part 242 of the guiding slider 24 slide past the pin 12 in sequence until the buffer block 15 presses against the pressing part 212 correspondingly. Then move the second support 21 leftward. When the guiding part 242 slides past the pin 12, the whole guiding slider 24 moves along the end of the sliding rod 22, and the abutting part 241 moves along the sliding rod 22 and is embedded into the groove 231. The abutting part 241 and the inclined surface outside the guiding part 242 form a connection. Then the guiding part 242 and the buckle 23 slide past the pin 12 in sequence until the locking component 1 and the buckling component 2 are completely unlocked, as shown in Figure 8 . The guiding slider 24 also moves and resets along the sliding rod 22 towards the second support 21 under the action of the elastic force of the second return spring 25, waiting for the next locking, as shown in Figure 7 .

[0039] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model.
