The first frame 231 and the second frame 232 are both fixed on the movable platform 2514 and can move along with the movement of the movable platform 2514 . The advantage of this arrangement is that only one first length driving unit is needed to drive the first frame 231 and the second frame 232 to move at the same time.

In other embodiments, the first length adjustment mechanism may also be in other forms, such as using two driving units that are respectively connected to the first frame 231 and the second frame 232 to drive their movements.

One end of the connecting transmission member 263 connected to the first frame 231 and the second frame 232 is an output end. The connecting transmission member 263 is rigid, so that when the telescopic rod 262 moves linearly, the connecting transmission member 263 is driven to move and rotate at the same time, pulling the first frame 231 and the second frame 232 close to the width adjustment mechanism 260 or away from the width adjustment mechanism 260 to achieve The moving path of the power exchange device 200 is the same linear motion, thereby adjusting the width. The first frame 231 and the second frame 232 are both slidably mounted on guide rails fixed on the power exchange equipment 200 to guide their movement. The laying direction of the guide rails is the same as the movement path of the power exchange equipment 200 .

In this solution, the hydraulic cylinder and telescopic rod need to be arranged along the traveling direction of the power exchange equipment. Compared with this solution, this embodiment By connecting the transmission member 263, only one telescopic rod is needed to achieve the effect of moving both ends. The structure is simpler and more reliable, and arranging the width adjustment mechanism and the length adjustment mechanism in the same direction can also facilitate the connection of hydraulic pipelines.

In addition, the third frame 241 and the fourth frame 242 move synchronously with the first frame 231 and the second frame 232 . When adjusting the width of the third frame 241 and the fourth frame 242, they also adjust synchronously with the first frame 231 and the second frame 232. Only one width adjustment mechanism 260 is needed to realize the width adjustment of the four frames. The third frame 241 and the fourth frame 242 do not need to be separately provided with a width adjustment mechanism 260, which makes the structure more compact and helps reduce costs.

The structure is compact, and it is convenient for the electronic control device to control the work of the hydraulic oil tank, shortening the power supply. The connection line between the control device and the hydraulic oil tank.

As shown in FIG. 8 , the electronic control device 280 and the hydraulic oil tank 270 are disposed on the same side of the power exchange device 200 in the direction perpendicular to the driving direction of the vehicle 500 . It is beneficial to reduce the length of the power swapping device 200 in the driving direction of the vehicle 500 .

In this embodiment, both the length adjustment mechanism and the width adjustment mechanism are driven by hydraulic pressure. All hydraulic cylinders are connected to the hydraulic oil tank 270 provided on the power exchange equipment, and the hydraulic oil tank 270 provides pressure. The hydraulic oil tank 270 has multiple parallel output ports, which are respectively connected to different hydraulic cylinders. Each output port is provided with an electronically controlled valve. The opening and closing of each electronically controlled valve is controlled through the electronic control device 280 to achieve length adjustment. Separate control of the mechanism and width adjustment mechanisms and their sub-mechanisms.

In addition, the lifting mechanism 210 is also hydraulically driven and controlled by the electronic control device 280 .

In this embodiment, a hydraulic cylinder is used to provide power, which is easy to control, can perform stepless speed regulation, and has an overload protection function. Compared with mechanical transmission, the arrangement of the lifting mechanism 210 is more flexible, has a simple structure, and has a large driving force. , lower cost than other drive devices.

In other embodiments, whether it is a length adjustment mechanism, a width adjustment mechanism or a lifting mechanism, in addition to using hydraulic drive, other common driving power sources can also be used to achieve their basic functions, such as using a motor solution, etc., and only need to Just replace the drive unit of each device with a motor and adjust the setting position and other corresponding structures accordingly.

Although specific embodiments of the present invention have been described above, those skilled in the art should understand that these are only examples, and various changes or changes can be made to these embodiments without departing from the principles and essence of the present invention. Revise. Accordingly, the scope of the present invention is defined by the appended claims.
