[0027] The lifting assembly 2 includes a pair of lead screws 20, which are movably mounted in the first protective shell 11 through the bearing seat 3. A transmission gear 21 is provided at the same end of the two lead screws 20. The two transmission gears 21 are connected to each other through a chain 22. A motor 23 is installed at the bottom of one of the lead screws 20.

[0028] The fixed protection assembly 5 includes a fixed box 50, and driving members 51 are symmetrically arranged on both sides of the fixed box 50. The two driving members 51 are respectively threadedly installed on the lead screw 20. A placement groove 516 is opened on the front of the fixed box 50, and slots 52 communicating with the placement groove 516 are symmetrically opened on both sides of the fixed box 50. Support members 53 are symmetrically arranged on the two top corners of the fixed box 50, and an inverted "L"-shaped member 59 is movably installed on the support member 53. A torsional The torsion spring 510 is provided at one end of the bottom of the inverted "L"-shaped member 59, and a movable cavity 511 is provided in the movable cavity 511. An inverted "U"-shaped block 512 is movably provided in the movable cavity 511. A plurality of springs 513 are provided on the top of the inverted "U"-shaped block 512. The other end of the springs 513 is connected to the inner top surface of the movable cavity 511. A limit rod 514 is movably provided at the bottom of the inverted "U"-shaped block 512. The limit rod 514 is movably installed in the slot 52.

[0029] A mounting shell 54 is disposed on the top of the fixed box 50. The mounting shell 54 is located below the other end of the two inverted "L"-shaped members 59. A pressure rod 56 is movably disposed on the mounting shell 54. A pressure plate 57 is disposed at one end of the pressure rod 56 located in the mounting shell 54. A spring 55 is disposed in the mounting shell 54. The spring 55 is abutted between the pressure plate 57 and the bottom surface of the mounting shell 54. A pair of inverted "L"-shaped pressure bars 58 are symmetrically disposed on both sides of the pressure rod 56.

[0031] As a preferred solution of the utility model, by providing a sealing ring 41 and a sealing groove 515, the sealing performance of the charging gun 4 during storage is enhanced to prevent dust, water vapor, etc. from entering, thereby protecting the charging gun 4 and internal components; by providing a second protective shell 12, the transmission gear 21 and the motor 23 are protected to avoid external interference and damage, thereby ensuring the reliability of the transmission and the normal operation of the motor 23.

[0032] When in use, when the user clicks on the charging pile 10, the motor 23 starts to rotate forward, and the motor 23 drives one lead screw 20 to rotate, and then the other lead screw 20 rotates synchronously through the cooperation of the transmission gear 21 and the chain 22. At this time, the rotation of the two lead screws 20 drives the fixed box 50 to move downward until it reaches a lower position, and then the motor 23 is turned off;

[0033] Then, the user needs to hold the charging gun 4 tightly with one hand and press the pressing rod 56 with the other hand. Driven by the pressing rod 56, the two inverted "L"-shaped pressing rods 58 press one end of the inverted "L"-shaped member 59, and the inverted "L"-shaped member 59 will rotate with the axis in the support member 53 as the center of the circle, so that the other end of the inverted "L"-shaped member 59 moves backward and upward, and the inverted "U"-shaped block 512 will drag the limiting rod 514 out of the card slot 43, and then the charging gun 4 can be pulled out for charging. After releasing the hand pressing the pressing rod 56, under the action of the torsion spring 510 and the spring 1 55, the inverted "L"-shaped member 59 and the pressing rod 56 will automatically reset;

[0034] After charging is completed, the user only needs to insert the charging gun 4 into the placement slot 516 and push it forward. During this process, the tops of the two limit rods 514 will continue to squeeze along the ramp slot 42 and then retract until the charging gun 4 is fully inserted into the placement slot 516. The limit rod 514 just moves to the position of the card slot 43. Under the action of the torsion spring 510, the limit rod 514 is snapped into the card slot 43 to complete the fixation, and then the motor 23 will reverse and raise the fixed protection component 5 to the top.
