[0051] In the embodiment, the bearing bracket is arranged on the rear beam plate, and the bearing bracket is connected with the upper rotating shaft assembly and the lower rotating shaft assembly.

[0052] Reference Figure 2 and Figure 3 The limiting assembly includes electromagnets 56 arranged on the support 51 and the rotating plate 53 respectively, and the electromagnets 56 are connected with the power supply and the motor 4 at two ends respectively, and the motor 4 is electrically connected to the upper rotating shaft assembly 35. In the embodiment, the electromagnets 56 include a first electromagnet and a second electromagnet, and the two electromagnets generate an attractive force after being electrified. The rotating plate 53 is driven to rotate around the hinge shaft 531 under the action of the attractive force, and after being rotated to a position, the rotating plate 53 is in contact with the micro switch 52, so that the power supply of the motor 4 is turned on, the motor 4 is positively rotated, the upper rotating shaft assembly 35 is driven to rotate, and then the battery 1 is driven to enter the battery compartment 2.

[0054] Reference Figures 1 to 9 For the working process in the electrified scene, the working process is described in detail. The micro locking device 5 is in a free state. Due to the force of the spring 55, the clamping tooth 57 on the rotating plate 53 is engaged with the gear 351 on the upper rotating shaft assembly 35, the entire battery replacement mechanism is locked, the battery 1 cannot move relative to the roller assembly 32, and the battery 1 is more stable during transfer; when the forward switch of the motor 4 is pressed, the electromagnets 56 arranged above and below generate an attractive force, the rotating plate 53 is driven to rotate along the hinge shaft 531 due to the action of the attractive force, and reference Figure 3When the rotating plate 53 rotates to its position, it contacts the micro switch 52, and the contacts of the micro switch 52 are compressed, thereby turning on the power to the motor 4.

Conversely, when the reverse switch of the motor 4 is pressed, the battery 1 can enter the battery compartment 2.

[0055] In manual operation, i.e., when there is no power or an electrical component malfunctions, the micro-motion locking device 5 is locked. When replacing the battery, refer to... Figure 4 To perform manual operation, pull the second handle 54 upwards. When the bottom end of the locking plate 541 on the handle 54 is higher than the upper surface of the support 51, rotate it at a certain angle to fix it, thereby realizing the rotation of the rotating plate 53 and disengaging the locking teeth 57 from the upper rotating shaft assembly 35.

Conversely, by adjusting the rotation direction of the first handle 352, the battery 1 can be put into the battery compartment 2.

[0056] Furthermore, this invention utilizes height-adjustable casters to pair with forklifts of varying tonnages and heights for battery transport. The left and right guide plates are adjustable to accommodate batteries of different tonnages and sizes. A micro-locking device provides mechanical locking, enhancing stability during battery transport. When powered, the micro-locking device electrically unlocks and automatically powers the motor, which drives the upper rotating shaft assembly, which in turn drives the first chain and pull rope. The first chain drives the lower rotating shaft, which in turn drives the second chain, which in turn drives the roller assembly. The pull rope hooks onto the battery lifting lugs, allowing the battery to move in and out of the battery compartment, simplifying battery replacement. In case of motor failure or malfunction, manual unlocking is possible, using the first handle to crank the upper rotating shaft assembly for battery replacement. This invention is applicable in various scenarios. The lower rotating shaft assembly can be expanded to allow multiple batteries to be replaced together or separately. For customers with many vehicles, it can be expanded into a battery swapping station. The expansion is convenient, the batteries do not require special equipment treatment, it is very user-friendly for customers who already have many batteries, has good versatility, and does not require modification.
