[0002] New energy vehicles mostly use lithium batteries as power battery packs, and lithium batteries will be damaged when discharging or charging at low temperatures. Therefore, new energy vehicles are equipped with a water cooling system to cool or heat the lithium batteries so that the lithium batteries can be maintained at a suitable temperature. However, some water cooling systems still require lithium batteries to power them, resulting in the lithium batteries still being in a low-temperature working state at the beginning of the water cooling system, which will also cause damage to the lithium batteries. Therefore, a vehicle-mounted backup battery is required.

[0003] However, in the prior art, it is difficult to quickly and conveniently remove most of the on-board backup batteries after installation, which not only reduces the disassembly efficiency of the on-board backup batteries, but also affects the normal use of the on-board backup batteries. For example, a Chinese utility model patent with announcement number CN219650992U provides a on-board backup battery mechanism, including a fixing frame and an energy storage battery, the energy storage battery is a lead-acid battery, a first connector and a second connector are connected to the fixing frame, one end of the first connector is connected to a first wire for electrically connecting to a vehicle power supply, and one end of the second connector is connected to a second wire for connecting to a vehicle water cooling system, a first interface and a second interface are provided on the energy storage battery, the other end of the first connector is movably plugged into the first interface and electrically connects the energy storage battery to the vehicle power supply, and the other end of the second connector is movably plugged into the second interface and electrically connects the energy storage battery to the vehicle water cooling system, and a limit assembly for fixing the fixing frame and the energy storage battery is also connected to the fixing frame; the technical problem that at the beginning of the water cooling system of the new energy vehicle in the prior art, the lithium battery may still be in a low-temperature working state and be damaged is solved.

[0004] Although the above-mentioned vehicle backup battery mechanism can solve the damage to the lithium battery at the beginning of the water cooling system startup, it is difficult to remove the above-mentioned vehicle backup battery mechanism quickly and conveniently after installation, which not only reduces the removal efficiency of the vehicle backup battery, but also affects the normal use of the vehicle backup battery.

[0044] When the vehicle-mounted backup battery mechanism needs to install the backup battery body 1, first, the end of the guide block 502 is brought into contact with the end of the guide groove 501, and the guide block 502 is made to slide in the guide groove 501, so that the battery body 101 moves in the connecting frame 202. When the inclined surface of the arc-shaped fixing block 304 is in contact with the end of the sleeve groove 302, the inclined surface of the arc-shaped fixing block 304 will squeeze the end of the sleeve groove 302, so that the elastic block 4 is deformed by force, and the six fixing members 303 are relatively tilted until the arc end of the arc-shaped fixing block 304 is in contact with the inner wall of the interface A203 and the interface B204. At this time, the elastic block 4 no longer deforms. When the arc end of the arc-shaped fixing block 304 is in contact with the fixed When the inner wall of the fixed groove 305 is in contact, the elastic block 4 is no longer subjected to force and begins to deform in the opposite direction, causing the six fixing members 303 to tilt away from each other until the arc-shaped fixing block 304 is engaged with the fixing groove 305. At this time, the elastic block 4 returns to its original shape, the end face of the fixing sleeve 301 is in contact with the inner wall of the sleeve groove 302, and the side surface of the battery body 101 is in contact with the side surface of the fixing plate 201, thus completing the installation of the backup battery body 1. When the backup battery body 1 needs to be disassembled, the battery body 101 is moved away from the fixing plate 201, so that the arc-shaped fixing block 304 is disengaged from the fixing groove 305, and the guide block 502 is disengaged from sliding in the guide groove 501.
