[0051] For example, the battery swap cabinet and the electric vehicle are respectively provided with battery compartments, the batteries can enter and exit the battery compartments, the batteries are taken as transfer objects, and the batteries are transferred between the battery swap cabinet and the electric vehicle through the transfer trolley.

[0052] For another example, the battery swap cabinet and the electric vehicle are respectively provided with battery compartments, the batteries are placed in the battery compartments, the battery compartments are taken as transfer objects, and the batteries are transferred between the battery swap cabinet and the electric vehicle through the transfer trolley.

[0053] The front of the battery swap cabinet is provided with a battery swap station.

[0054] The transfer trolley 10 comprises a first moving table 100. The first moving table 100 is configured to move along a first moving direction. The first moving table 100 is configured to move between the battery swap cabinet and the chassis of the electric vehicle, in other words, the first moving table 100 is configured to move between the battery swap cabinet and the battery swap station. The first moving direction is the horizontal direction between the battery swap cabinet and the battery swap station. Through the movement of the first moving table 100, the movement of the transfer trolley 10 between the battery swap cabinet and the battery swap station is realized.

[0055] Referring to Figure 1 , a guide rail 700 is arranged between the battery swap cabinet and the battery swap station, the guide rail 700 is arranged to extend between the battery swap cabinet and the battery swap station, the bottom of the first moving table 100 is provided with a roller 120 and a driving mechanism (not shown), and the driving mechanism is configured to drive the roller 120 to move along the guide rail 700.

For example, the driving mechanism comprises a motor, the power shaft of the motor is connected with a gear, the gear is connected with a rotating rod through a belt, and the end of the rotating rod is provided with the roller 120.

[0057] The transfer trolley 10 further comprises a bearing table assembly arranged above the first moving table 100. The bearing table assembly is configured to bear the battery or the battery compartment. Specifically, in the scheme in which the battery is taken as the transfer object, the bearing table assembly bears the battery; and in the scheme in which the battery compartment is taken as the transfer object, the bearing table assembly bears the battery compartment.

[0058] The carrying table assembly comprises a laser ranging device 800 configured to detect the distance between the carrying table assembly and the target position. Specifically, when the transfer trolley 10 moves to the bottom of the vehicle to pick up the battery, the target position can be understood as the vehicle chassis or the battery compartment provided on the vehicle chassis, and the distance between the carrying table assembly and the vehicle chassis or the battery compartment is detected by the laser ranging device 800.

[0059] The carrying table assembly further comprises a lifting platform 300 and a lifting driving mechanism 500.

The lifting platform 300 can also adjust the inclination while realizing the lifting movement.

[0060] When replacing the battery, the first moving table 100 first moves along the guide rail 700 to the bottom of the electric vehicle; then the laser ranging device 800 detects the distance between the carrying table assembly and the vehicle chassis or the battery compartment; the laser ranging device 800 feeds back the detected distance data to the control system; the control system controls the lifting distance of the lifting driving mechanism 500 according to the received distance data, the lifting driving mechanism 500 drives the lifting platform 300 to rise, until the lifting platform 300 is close to and opposite to the battery compartment, and the lifting platform 300 maintains a parallel posture with the battery compartment, so that the lifting platform 300 can smoothly pick up the battery, improving the reliability of battery replacement.

[0061] After the electric vehicle stops at the battery replacement station, due to the difference in tire pressure of each tire and the uneven weight of the cargo, the vehicle itself may be inclined. When the vehicle is inclined, the battery compartment at the bottom of the vehicle is also inclined. In this embodiment, the laser ranging device 800 is used to detect the distance between the lifting platform 300 and the vehicle chassis or the battery compartment, and the lifting driving mechanism 500 controls the lifting distance of the lifting platform 300 according to the detected distance, so that the lifting platform 300 can adjust the inclination and be parallel to the battery compartment, thereby improving the reliability of picking up the battery or the battery compartment.

At this time, the lifting platform 300 can be adjusted in inclination by independent control of the plurality of lifting drive mechanisms 500, so that the lifting platform 300 can be parallel to the battery compartment, thereby improving the reliability of the battery or the battery compartment.

[0064] In some embodiments of the present application, the laser ranging device 800 and the lifting drive mechanism 500 are respectively provided with four, and the four lifting drive mechanisms 500 are connected to the four corners of the lifting platform 300.

[0068] In other words, the moving position of the transfer trolley 10 between the battery replacing cabinet and the electric vehicle is defined as forward and backward movement, and the second moving platform 200 moves left and right under the action of the transverse drive mechanism 400. When the electric vehicle is parked at the battery replacing station, the electric vehicle may deviate from the center line of the battery replacing station. At this time, the left and right positions of the bearing platform assembly relative to the battery compartment of the electric vehicle are adjusted by the left and right movement of the second moving platform 200.

[0069] In some embodiments of the present application, the bearing platform assembly includes a rotating platform 900. The rotating platform 900 is arranged on the lifting platform 300 and is configured to rotate under the action of the rotating drive mechanism 600.
