Of course, the connection relationship of the four is not limited to the above, and for example, the traveling mechanism, the turning mechanism, the lifting mechanism, and the first base 1 may be connected in this order. Specifically, the bottom of the slewing mechanism is connected with the travelling mechanism, the first end of the lifting mechanism is connected with the top of the slewing mechanism, and the second end of the lifting mechanism is connected with the first seat body 1. The lifting mechanism directly drives the first seat body to lift. The rotation mechanism drives the lifting mechanism to rotate, and then the lifting mechanism drives the first seat body to rotate.

For example, the mount may be connected to the cantilever member 10 by a flexible member, such as a wire rope. Damping pieces for preventing the installation seat from shaking are arranged around the installation seat. The damping member may be mounted on the cantilever member. Damping elements include, but are not limited to, springs, rubber blocks, or dampers. In the process of driving the battery module to move, particularly when the battery module is started and stopped, the top-replacing gripper device is easy to generate larger impact force due to large weight and large inertia of the battery module, so that weak links of the connecting structure of the top-replacing gripper device and the like are damaged. The top hand-changing device can generate displacement to squeeze the damping piece through the flexible piece, so that impact generated by the battery module is buffered, and the weak links are prevented from being damaged due to the impact. The damping piece is arranged to absorb energy generated by impact, so that shaking of the battery module is reduced or even avoided, and the battery module is placed in a battery bin or a battery mounting position of the electric vehicle by the battery replacing device.

When the vehicle 9 arrives, the traveling mechanism first brings the second grasping mechanism 3 into opposition to the battery mounting position of the vehicle 9, and the battery module 4 with the power shortage in the vehicle 9 is taken out. Then, the first grabbing mechanism 2 is opposite to the battery installation position of the vehicle 9 through the travelling mechanism, and the full-power battery module 4 grabbed by the first grabbing mechanism 2 is sent to the battery installation position of the vehicle 9, so that the power conversion process is completed. The battery module 4 of the insufficient power that the second snatched mechanism 3 snatched is sent into the left side in the first battery compartment, and the first battery compartment right side is vacant at this moment.
Then, the second gripping mechanism 3 grips the full battery module 4 from the left side in the second battery compartment before the next vehicle 9 arrives. After the vehicle 9 reaches, the battery module 4 of the vehicle 9, which is lack of power, is grabbed by the first grabbing mechanism 2, and the battery module 4 of full power grabbed by the second grabbing mechanism 3 is sent to a battery installation position of the vehicle 9, so that the power changing process is completed. The battery module 4 of the insufficient power that first snatch mechanism 2 snatched is sent into the right side in the first battery compartment, and the left side of second battery compartment is vacant this moment. Thus, the full battery modules 4 in each battery compartment are sequentially grasped, and the battery modules 4 with the power shortage are sequentially placed in the idle battery compartments. It should be noted that "power shortage" as used herein includes, but is not limited to, low power content of the battery module 4.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
