Two ends of the variable pitch connecting rod 4 are respectively connected with a sliding block 6 and two side shear type lifting frames. The thread directions of two ends of the adjustable screw are centrosymmetric reverse threads, and the variable-pitch slide block 6 is arranged on the screw through the central threads. As shown in the attached figure 4, when the adjustable screw rotates clockwise, the two variable-pitch sliding blocks 6 move outwards in opposite directions synchronously, so that the variable-pitch connecting rods 4 are driven to open, the lifting frames on the two sides are driven to open, and the distance between the lifting frames on the two sides is increased. When the screw rotates counterclockwise, the pitch becomes smaller. The adjustable screw and the variable-pitch sliding block are arranged in the central guide rail 7 to form an integral component.
As shown in fig. 5, the wheel clamping devices 3 at the two ends of the scissor lift are driven by the symmetrical racks 9 and the gears 8, and when the gears 8 rotate, the racks 9 are driven to drive the wheel clamping devices 3 to slide along the upper arm of the lift, so that the wheel clamping and lifting requirements for wheel clamping and lifting of wheel bases of different vehicle types can be met.
As shown in fig. 6, the wheel clamping device 3 is composed of a rotatable clamping upper arm 14, a fixed lower arm 15, a limit connecting rod 16 and a threaded pull rod 18, the rotatable clamping upper arm is connected with the threaded pull rod 18 through a cylindrical pin 17, and the threaded pull rod 18 is installed in a threaded hole on the fixed lower arm. The spacing link 16 acts to angularly adjust the rotatable upper arm 14.
As shown in the structural and operation diagram of the wheel clamping device shown in fig. 7, when clamping a vehicle wheel, the threaded pull rod 18 is driven by the driving device to move downward, and drives the rotatable clamping upper arm 14 to rotate counterclockwise until being parallel to the pull rod axis, at which time the rotatable clamping upper arm 14 and the fixed lower arm 15 are in an "F" shape. When the threaded pull rod 18 continues to move downwards, the connecting part of the pin shaft of the cylinder 17 is driven to enter the round hole of the fixed lower arm 15, the angle position of the rotatable upper arm 14 is fixed at the moment, and the rotatable upper arm can only continue to move downwards under the driving of the threaded pull rod 18 until the rotatable upper arm is in close contact with the vehicle wheel, so that the rotatable upper arm and the lower arm complete the wheel clamping action together. The unlocking action of the clamping mechanism is opposite to that of the clamping mechanism, and the unlocking of the wheels and the rotating and retracting action of the upper arm can be completed only by driving the threaded pull rod to move upwards.
Fig. 8 is a schematic diagram of a planar structure of an electric exchanging robot, which is composed of 4 wheels of adjustable suspension height driving wheels 10, a central guide groove 19, a battery assembly handling mechanical arm 20 and a power and equipment bin 21.

When the shock-absorbing cylinder 13 extends, the swing arm 22 is pressed downwards, the height of the center of the driving wheel 12 and the pin 11 is increased, the chassis of the electric replacing robot rises, and the top working surface rises. When the shock-absorbing cylinder 13 is shortened, the swing arm 22 is lifted, the central height of the driving wheel 12 and the pin 11 is reduced, the chassis of the battery replacement robot descends, and the top working surface is separated from the chassis of the battery assembly.
Fig. 10 is an operation diagram of a power exchanging flow of the combined power exchanging robot. The method comprises the steps of firstly completing registration and identification of a battery replacing vehicle, obtaining related vehicle width, wheel base and battery pack installation information according to the vehicle type, then adjusting the wheel base of a clamping mechanism according to the information by a lifting robot, and planning an action route. After adjustment is completed, the combined battery replacing robot moves to the bottom of the vehicle as a whole, when the position of a rear wheel is detected, the lifting robot expands the lifting frame to the positions of the wheels on two sides, and when the lifting frame expands to the position that the clamping device 3 abuts against the inner sides of the wheels, the lifting frame is expanded. The lifting robot drives the clamping device 3 again to adjust the wheel base, and when the clamping device fixes the inner arm 15 to be contacted with the inner edge of the wheel, the wheel base adjustment is completed. The clamping device 3 continues to drive the rotary outer arm 14 to tightly clamp the outer edge of the wheel, the wheel of the vehicle 4 is clamped, and the lifting robot finishes positioning the vehicle. The battery replacement robot moves along the central guide rail 7 according to the parameters of the vehicle battery assembly to complete the positioning of the battery assembly. After the positioning is finished, the battery replacement robot raises the driving wheel until the working surface is in close contact with the battery assembly chassis. Then the battery pack is unlocked by the battery pack assembling and disassembling mechanical arm, and the battery pack is separated from the vehicle. After the battery assembly is disassembled, the battery replacement robot instructs the lifting robot to lift the vehicle, and an operation space is provided for battery hauling. After the lifting is finished, the battery replacing robot transports the disassembled battery assembly out of the battery replacing station and transports the battery assembly to the battery replacing station storage rack along the central guide rail 7. And then, the battery replacement robot can be selected to reload the full-charge battery, or another battery replacement robot with the loaded battery can be selected to be standby. When the front replacement electric robot is pulled out, the standby replacement electric robot is pulled in and installed along the central guide rail 7, so that the assembly line operation is carried out, and the replacement speed is greatly improved. The battery assembling and disassembling process is opposite, firstly the battery replacing robot adjusts the position along the central guide rail 7, after the adjustment is completed, the lifting robot is informed to reduce the height of the vehicle until the battery component is combined with the vehicle, and then the battery component is locked by the assembling and disassembling mechanical arm of the battery replacing robot. After the battery is locked, the battery replacing robot lowers the suspension height to be separated from the battery chassis, the lifting robot continues to lower the height until the wheels naturally contact the ground, then the wheel clamping mechanism is unlocked, and the distance between the lifting frames is shortened. The lifting robot and the battery replacement robot are combined into a whole to be driven out of the vehicle chassis, and the whole battery replacement operation is completed.
