[0045] An operating method of a multifunctional energy storage device for a motor home comprises the following steps:

[0046] S1: Rotate the protective cover 11, place the battery body 8 on the support table 604 and push it inwards. When the outer wall of the battery body 8 on the inside of the protective box 1 abuts against the outer wall of the lifting plate 702, the lifting plate 702 will be rotated on the outer wall of the lifting block 701, causing the lifting rod 703 to push the support table 604 upwards. While moving upwards, the support table 604 stretches the tension spring 602 through the support rod 603. When the lifting plate 702 abuts against the bottom of the support table 604, the support table 604 drives the battery body 8 upwards, causing the battery electrode column 9 to be inserted into the rotating electrode cap 403 and the output electrode cap 306.

[0047] S2: When the connection mode of the battery needs to be converted, push the pressing pipe 202 downwards. The pressing pipe 202 drives the abutting block 206 to slide in the guide pipe 207 through the pin block 204. Since the pressing pipe 202 is locked by the support frame 201, the abutting block 206 drives the guide pipe 207 to rotate. The guide pipe 207 drives the conversion disc 209 to rotate through the conversion rod 208. The conversion disc 209 drives the annular plate 301 to move through the push rod 210. Since the inner wall at the bottom of the tooth plate 302 is in sliding connection with the outer wall of the guide strip 303, the annular plate 301 converts the rotary motion of the push rod 210 into linear motion, causing the tooth plate 302 to drive the rotating gear 402 to rotate under the meshing force. The rotating gear 402 drives the rotating rod 401 to rotate in the fixed plate 304. The rotating rod 401 drives the rotating electrode cap 403 to rotate. The rotating electrode cap 403 drives the rotating protrusion 404 to move in the first stroke, causing the pull rope 510 to move through the insertion column 509, driving the locking block 508 to enter the conductive plate 501. The inner wall on 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 insertion column 509 under the extension force of the locking spring 505. The rotating protrusion 404 abuts against the inner wall of the arc-shaped slot in the second stroke, causing the conductive plate 501 to rotate and abut against the conductive block 504, which is then pushed into the insulating bin 502. The conductive plate 501 is inserted into the conductive block 504 through the extension force of the reset spring 503 and abuts against one side of the locking plate 506, causing the other side of the locking plate 506 to be separated from the insertion column 509. The locking block 508 is extended and retracted from the conductive plate 501 under the extension force of the locking spring 507, completing the locking of the conductive block 504 and realizing the conversion of the battery pack from parallel connection to series connection.

After the outer wall of the battery body (8) located inside 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. While the support platform (604) moves upward, it stretches the tension spring (602) through the support rod (603). When the lifting plate (702) drives the lifting rod (703) to abut against the bottom of the support platform (604), the support platform (604) drives the battery body (8) to move upward, so that the battery electrode post (9) is inserted into the rotating electrode cap (403) and the output electrode cap (306).

The pressing tube (202) drives the abutment block (206) to slide in the guide tube (207) through the pin block (204). Since the pressing tube (202) is locked by the support frame (201), the abutment block (206) drives the guide tube (207) to rotate.

Since the toothed plate (302) The inner wall of the bottom is slidably connected to the outer wall of the guide bar (303). The annular plate (301) converts the rotational motion of the push rod (210) into linear motion, causing the toothed plate (302) to drive the rotating gear (402) to rotate under the meshing force. The rotating gear (402) drives the rotating rod (401) to rotate within the fixed plate (304). The rotating rod (401) drives the rotating electrode cap (403) to rotate. The rotating electrode cap (403) drives the rotating protrusion (404) to rotate. The rotating protrusion (404) will drive the pull rope (510) to move during the first stroke. The pull rope (510) drives the locking block (508) to be drawn into the conductive plate (501) through the plug-in post (509), causing the inner wall of one side of the conductive plate (501) to disengage 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 post (509) under the extension and contraction force of the locking spring (505). The rotating protrusion (404) abuts against the inner wall of the arc groove in the second stroke. The rotating protrusion (404) drives the conductive plate (501) to rotate.

After the conductive plate (501) passes through, under the extension and retraction force of the return spring (503), the conductive block (504) will be inserted into the conductive plate (501) and abut against one side of the locking plate (506), so that the other side of the locking plate (506) will be disengaged from the plug post (509). Under the extension and retraction force of the locking spring (507), the locking block (508) will extend and retract 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 connection. S3: When the battery body (8) is depleted, by rotating the rotating handle (608), the limiting block (607) pushes the limiting spring (606) to begin to contract. After the rotating handle (608) passes through, the limiting block (607) is pushed out again so that the top of the limiting block (607) overlaps with the bottom of the rotating handle (608), pushing the sliding rod (610) so that the sliding rod (610) abuts against the adjacent extension plate (609), completing the connection of the rotating handle (608). At this time, push the rotating handle downward ( 608), turn the handle (608) to drive the support platform (604) to move downward. The support platform (604) pushes the lifting rod (703) to move. The lifting rod (703) drives the lifting plate (702) to rotate, so that the lifting rod (703) is inserted into the slot, and the lifting plate (702) is locked. During the rotation of the lifting plate (702), the battery body (8) will be pushed outward.
