A second motor 334 is installed on the left side of the lifting seat 31. A second bidirectional screw 335 driven by the second motor 334 is rotatably connected to the inner side of the lifting seat 31 along the X axis. A group of limit frames 336 slidably connected to the limit frame 333 are respectively threadedly connected on the left and right sides of the second bidirectional screw 335. The limit frame 336 is slidably connected to the lifting seat 31.

[0025] The electric slide rail 21 is arranged on the bottom plate 1 along the Y axis, and the electric slide rail 21 and the cylinder assembly 23 are electrically connected to the external controller; the output end of the first motor 331 is coaxially fixedly connected to the first bidirectional screw 332, and the second motor 334 is coaxially fixedly connected to the second bidirectional screw 335, and the first motor 331 and the second motor 334 are both servo motors; the first bidirectional screw 332 is located on the upper side of the second bidirectional screw 335 and is staggered in the lifting seat 31, and the lifting seat 31 is provided with slots near the first bidirectional screw 332 and the second bidirectional screw 335, and a movable slot is provided in the limit frame 333 that is slidably connected to the limit frame 336; the limit frame 334 is provided with a movable slot that is slidably connected to the limit frame 336; 33.

The first motor 331, the first bidirectional screw 332, the two sets of limit frames 333, the second motor 334, the second bidirectional screw 335, and the two sets of limit frames 336 are used to position and clamp the left and right sides and the front and back sides of the PACK battery pack without interfering with each other.

[0026] The second implementation mode is mainly different from the first implementation mode in that:

[0027] The auxiliary lifting member 32 includes a connecting frame 321 installed at the middle end of the bottom of the lifting seat 31, an electric push rod assembly 322 is vertically installed at the bottom of the connecting frame 321, and a movable plate 323 is set at the top extended end of the electric push rod assembly 322.

[0028] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0029] When in use, the user moves the moving seat 22, the cylinder assembly 23, and the positioning member 3 to the PACK battery pack loading end through the electric slide rail 21, and places the PACK battery pack on the receiving plate 325 in the middle of the lifting seat 31 through the external loading member, and starts the first motor 331. The first motor 331 drives the two sets of limit frames 333 to slide along the upper side of the lifting seat 31 through the first bidirectional screw 332. After the two sets of limit frames 333 clamp the front and rear sides of the PACK battery pack respectively, the first motor 331 is turned off. During this process, the two sets of limit frames 333 move along the Y axis along the limit frame 336, and then the second motor 334 is started. The second motor 334 drives the two sets of limit frames 336 to move along the inner slide groove of the limit frame 333 along the X axis through the second bidirectional screw 335 and finally clamp the left and right sides of the PACK battery pack.

After the PACK battery pack is inserted into the installation side, the cylinder assembly 23 is closed. If the upper side of the clamping member 33 fits with the lower side of the installation end, affecting the installation of the PACK, the electric push rod assembly 322 is started. The electric push rod assembly 322 drives the movable plate 323, the slide rod 324, and the receiving plate 325 to push up the PACK battery pack to promote its insertion into the installation end. The electric slide rail 21 is a prior art, and its specific working principle is not repeated here.
