When the rotating handle is stored inside the support platform, the limit block will be inserted into the positioning hole under the telescopic force of the limit spring to complete the positioning.

[0015] Preferably, the method for operating the multifunctional energy storage device for a motorhome comprises the following steps:

[0016] S1: Rotate the protective cover, place the battery body on the support platform and push it inward. After the outer wall of the battery body on the inner side of the protective box abuts against the outer wall of the lifting plate, it will push the lifting plate to rotate on the outer wall of the lifting block, so that the lifting rod pushes the support platform to move upward. While the support platform moves upward, it stretches the tension spring through the support rod. When the lifting plate drives the lifting rod to abut against the bottom of the support platform, the support platform drives the battery body to move upward, so that the battery electrode column is inserted into the rotating electrode cap and the output electrode cap.

[0017] S2: When the connection mode of the battery needs to be changed, the pressing tube is pushed downward, and the pressing tube drives the moving block to slide in the guide tube through the pin block. Since the pressing tube is locked by the support frame, the moving block drives the guide tube to rotate, and the guide tube drives the conversion disk to rotate through the conversion rod, and the conversion disk drives the annular plate to move through the push rod.

The rotating protrusion will drive the pull rope to move in the first stroke, and the pull rope will pass The locking block is driven by the plug-in column to be received into the conductive plate, so that the inner wall of one side of the conductive plate is separated from the outer wall of the rotating electrode cap and the output electrode cap. At this time, the locking plate is inserted into the plug-in column under the telescopic force of the locking spring, and the rotating protrusion abuts against the inner wall of the arc groove in the second stroke. The rotating protrusion drives the conductive plate to rotate, and the conductive plate and the conductive block will be pushed into the insulating bin after abutting. After the conductive plate passes, the conductive block is inserted into the conductive plate and abuts against one side of the locking plate under the telescopic force of the reset spring, so that the other side of the locking plate is separated from the plug-in column. Under the telescopic force of the locking spring, the locking block is retracted from the conductive plate to complete the locking of the conductive block, thereby realizing the conversion of the battery pack from parallel to series.

[0018] S3: When the battery body is out of power, by turning the rotating handle, the limit block pushes the limit spring to start shrinking, and after the rotating handle passes, the limit block is pushed out again so that the top of the limit block overlaps with the bottom of the rotating handle, pushing the sliding rod so that the sliding rod abuts against the adjacent extension plate to complete the connection of the rotating handle. At this time, the rotating handle is pushed downward, and the rotating handle drives the support platform to move downward, and the support platform pushes the lifting rod to move, and the lifting rod drives the lifting plate to rotate, so that the lifting rod is inserted into the slot to complete the locking of the lifting plate. During the rotation process, the lifting plate will push the battery body to move outward, and after the support platform loses its supporting force and moves downward, the battery body also protrudes from the protective box.

[0021] (2) The multifunctional energy storage device and operation method for RVs controls the coordinated use of the transmission group, the rotating group and the conductive group through the conversion component. After completing the conversion between parallel and series connection, the device can be used directly without the need for additional waiting time.

[0022] (3) The multifunctional energy storage device and operation method for RVs can more conveniently install or remove batteries from the energy storage device through the coordinated use of the support assembly and the lifting assembly, bringing convenience to the maintenance and replacement of the staff.

[0045] A method for operating a multifunctional energy storage device for a motorhome comprises the following steps:

[0046] S1: Rotate the protective cover 11, place the battery body 8 on the support platform 604 and push it inward. After the outer wall of the battery body 8 located on the inner side of the protective box 1 abuts against the outer wall of the lifting plate 702, it will push the lifting plate 702 to rotate on the outer wall of the lifting block 701, so that the lifting rod 703 pushes the support platform 604 to move upward.

Since the inner wall of the bottom of the tooth plate 302 is slidably connected with the outer wall of the guide strip 303, the annular plate 301 converts the rotational motion of the push rod 210 into a linear motion, so that the tooth plate 302 drives the rotating gear 402 to rotate under the meshing force, and the rotating gear 402 drives the rotating rod 401 to rotate in the fixed plate 304, and the rotating rod 401 drives the rotating electrode cap 403 to rotate, and the rotating electrode cap 403 drives the rotating protrusion 404 to rotate, and the rotating protrusion 404 will drive the pull rope 510 to move in the first stroke. The pull rope 510 drives the locking block 508 to be received into the conductive plate 501 through the plug-in column 509, so that the inner wall of one side of the conductive plate 501 is separated from the outer wall of the rotating electrode cap 403 and the output electrode cap 306. At this time, the locking plate 506 is inserted into the plug-in column 509 under the telescopic force of the locking spring 505, and the rotating protrusion 404 abuts against the inner wall of the arc groove in the second stroke, and the rotating protrusion 404 drives the conductive plate 501 to rotate, and the conductive plate 501 abuts against the conductive block 504. After that, the conductive block 504 will be pushed into the insulating compartment 502. After the conductive plate 501 passes through, the conductive block 504 is inserted into the conductive plate 501 under the telescopic force of the reset spring 503 and abuts against one side of the locking plate 506, so that the other side of the locking plate 506 is disengaged from the plug-in column 509. Under the telescopic force of the locking spring 507, the locking block 508 is telescoped from the conductive plate 501 to complete the locking of the conductive block 504, thereby realizing the conversion of the battery pack from parallel to series.

[0048] S3: When the battery body 8 is out of power, by rotating the rotating handle 608, the limit block 607 pushes the limit spring 606 to start shrinking. After the rotating handle 608 passes, the limit block 607 is pushed out again to make the top of the limit block 607 overlap with the bottom of the rotating handle 608, and the sliding rod 610 is pushed to make the sliding rod 610 abut against the adjacent extension plate 609 to complete the connection of the rotating handle 608. At this time, the rotating handle 608 is pushed downward, and the rotating handle 608 drives the support platform 604 to move downward. The support platform 604 pushes the lifting rod 703 to move, and the lifting rod 703 drives the lifting plate 702 to rotate, so that the lifting rod 703 is inserted into the card slot to complete the locking of the lifting plate 702. The lifting plate 702 will push the battery body 8 to move outward during the rotation process. After the support platform 604 loses its supporting force and moves downward, the battery body 8 also protrudes from the protective box 1.
