One end of the connecting spring 53 is fixedly installed on the side wall of the slide 52. The other end of the connecting spring 53 is fixedly installed on the inner wall of the slide rail 51. The elasticity of the connecting spring 53 can drive the slide 52 to slide and reset on the inner wall of the slide rail 51. The vertical rod 54 A slide groove 55 is provided on the top, a swing rod 57 is hinged on the outer wall of the charging pile body 1, one end of the connecting rod 58 is hinged on the outer wall of the swing rod 57, and the other end of the connecting rod 58 is hinged on the outer wall of the slide 52. The swing rod 57 rotates on the outer wall of the charging pile body 1 and cooperates with the connecting rod 58 to push the slide 52 so that the slide 52 will slide on the inner wall of the slide rail 51. The support rod 59 is fixedly installed on the outer wall of the charging pile body 1. The outer wall of the support rod 59 is slidably connected to the limit block 510, and the inner wall of the cable 2 is attached to the inner wall of the limit block 510. When the cable 2 is pulled and causes the charging pile body 1 to move forward or backward When tilting backward, the cable 2 will push the limit block 510, causing the limit block 510 to slide on the outer wall of the support rod 59. The outer wall of the limit block 510 is fixedly installed with an L rod 511. When the limit block 510 slides, it will drive the L rod 511 to move synchronously.

The boss 512 is fixedly installed on the top of the charging pile body 1. When the cable 2 is pulled and causes the charging pile body 1 to tilt to the left or right, the charging pile body 1 will drive the boss 512 to tilt synchronously.

[0021] The inner wall of the slide 52 is slidably connected to a vertical rod 54, and a counterweight block 56 is fixedly installed at the bottom of the vertical rod 54. The slide 52 slides on the inner wall of the slide rail 51, and the vertical rod 54 and the counterweight block 56 cooperate to adjust the center of gravity of the charging pile body 1 to prevent the charging pile body 1 from tipping forward or backward, thereby improving the stability of the charging pile body 1.

The outer wall of the T-bar 514 fits against the inner wall of the slide groove 55. When the charging pile body 1 tilts to the left or right, the counterweight ball 513 on the inner wall of the boss 512 will rotate as the center of gravity of the charging pile body 1 changes. While the counterweight ball 513 rotates, it can cooperate with the T-bar 514, the slide groove 55 and the vertical rod 54 to drive the counterweight block 56 to move in the opposite direction of the tilt direction of the charging pile body 1. At this time, the counterweight block 56 can be used to make the center of gravity of the charging pile body 1 deviate to the opposite direction of the tilt, thereby preventing the charging pile body 1 from tipping over to the left or right.

[0023] When this embodiment is working: when the cable 2 is pulled and causes the charging pile body 1 to tilt forward or backward, the cable 2 will push the limit block 510, so that the limit block 510 slides on the outer wall of the support rod 59. While the limit block 510 slides, it will drive the L rod 511 to move synchronously. When the L rod 511 contacts the swing rod 57 during the movement, it will squeeze the swing rod 57, so that the swing rod 57 rotates on the outer wall of the charging pile body 1. While the swing rod 57 rotates, it will push the connecting rod 58, so that the connecting rod 58 pushes the slide 52.

At the same time, the slide 52 will drive the vertical rod 54 to gradually move away from the charging pile body 1, so that the vertical rod 54 drives the counterweight block 56 to gradually move away from the charging pile body 1, so that the counterweight block 56 and the limit block 510 can move in opposite directions. The movement of the counterweight block 56 can make the center of gravity of the charging pile body 1 tilted. In the opposite direction of the tilting direction of the charging pile body 1, the center of gravity shifting and tipping over can be avoided, thereby improving the stability of the charging pile body 1. When the cable 2 is pulled and causes the charging pile body 1 to tilt to the left or to the right, the charging pile body 1 will drive the boss 512 to tilt synchronously. At this time, the counterweight ball 513 on the inner wall of the boss 512 will rotate with the change of the center of gravity of the charging pile body 1. At the same time, the counterweight ball 513 will drive the T-shaped rod 514 to rotate in the opposite direction of the tilting direction of the charging pile body 1. At this time, the T-shaped rod 514 will fit on the inner wall of the slide groove 55 and move and push the vertical rod 54, so that the vertical rod 54 slides on the inner wall of the slide 52. At the same time, the vertical rod 54 will drive the counterweight block 56 to move in the opposite direction of the tilting direction of the charging pile body 1. At this time, the counterweight block 56 can be used to make the center of gravity of the charging pile body 1 deviate to the opposite direction of the tilt, thereby avoiding the charging pile body 1 from tipping over to the left or right.

The outer wall of the sliding frame 67 is fixedly installed with a limit spring 611. The end of the limit spring 611 away from the sliding frame 67 is fixedly installed on the top of the support rod 59.

[0025] A limiting plate 63 is fixedly installed at one end of the positioning rod 62, and a clamping plate 64 is fixedly installed at the other end of the positioning rod 62. The positioning rod 62 can drive the clamping plate 64 to clamp the cable 2 through the sliding cooperation of the slider 61. Clamping the cable 2 through the clamping plate 64 can reduce the tension at the connection between the cable 2 and the charging pile body 1, thereby preventing the cable 2 from being pulled and causing damage to the connection between the cable 2 and the charging pile body 1.

The slide plate 612 slides on the outer wall of the charging pile body 1 and gradually approaches the cable 2, which can drive the push rod 614 to fit the surface of the cable 2. At this time, the low push rod 614 can be used to limit the height of the cable 2, so that the cable 2 can be placed between the two sets of clamps 64, so that the clamps 64 can better clamp the cable 2.

[0027] The protective mechanism 7 includes a bottom cover 71, a top cover 72, a return spring 73, a limit rod 74 and a connecting rod 75.

[0029] When this embodiment is working: when the slide 52 drives the counterweight 56 ​​to gradually move away from the charging pile body 1, the slide 52 will drive the push rod 69 to move synchronously. When the push rod 69 contacts the bent rod 68 during the movement, it will squeeze the bent rod 68, so that the bent rod 68 drives the slide frame 67 to slide upward on the inner wall of the support rod 59. At the same time, the bent rod 68 will stretch the limit spring 611, and the slide frame 67 will drive the through groove 610 to squeeze the guide rod 66 while sliding upward, so that the guide rod 66 pushes the slide block 61. At this time, the slide block 61 will slide on the outer wall of the charging pile body 1 and gradually approach the cable 2. When the slide block 61 moves, it will drive the positioning spring 65 to move synchronously. When the positioning spring 65 moves, it will drive the limit plate 63 to move synchronously. When the limit plate 63 moves, it will drive the positioning rod 62 to move synchronously. At this time, the positioning rod 62 will drive the clamping plate 64 to gradually approach the cable 2. At this time, the two groups of sliders 61 can be used to make the positioning rod 62 drive the clamping plate 64 to clamp the two sides of the cable 2. Clamping the cable 2 by the clamping plate 64 can reduce the tension at the connection between the cable 2 and the charging pile body 1. The slider 61 will drive the guide rod 66 to move in contact with the inner wall of the inclined groove 613 in the process of gradually approaching the cable 2. At this time, the guide rod 66 will squeeze the inclined groove 613, so that the slide plate 612 slides on the outer wall of the charging pile body 1 and gradually approaches the cable 2. While the slide plate 612 slides, it will drive the telescopic spring 615 to move synchronously. While the telescopic spring 615 moves, it will drive the push rod 614 to gradually approach the cable 2, so that the push rod 614 can be fitted on the surface of the cable 2. At this time, the low push rod 614 can be used to limit the height of the cable 2, so that the cable 2 can be placed between the two groups of clamping plates 64 so that the clamping plates 64 can better clamp the cable 2.

[0030] As the slide plate 612 slides on the outer wall of the charging pile body 1 and gradually approaches the cable 2, it will push the connecting rod 75, causing the connecting rod 75 to push the limiting rod 74. At this time, the limiting rod 74 will slide on the inner wall of the charging pile body 1 and gradually slide out of the charging pile body 1. In this process, the limiting rod 74 will gradually separate from the bottom of the top cover 72. When the limiting rod 74 is completely separated from the bottom of the top cover 72, the limit on the top cover 72 will be released. At this time, the return spring 73 will pull the top cover 72 downward, causing the top cover 72 to slide downward on the outer wall of the charging pile body 1, thereby making the top cover 72 fit on the top of the bottom cover 71. At this time, the top cover 72 can cooperate with the bottom cover 71 to cover the charging gun 3 to prevent the charging pile body 1 from tipping over and causing damage to the charging gun 3.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
