Preferably, in this embodiment, the first battery rack 20a and the second battery rack 20b have the same number of layers, and the bearing surfaces of the layers correspond to each other one by one.

Preferably, in the present embodiment, the first battery rack 20a is used for placing the fully-charged electric power battery 30a and transmitting the fully-charged electric power battery 30a to the relay lifting platform 102a, and the second battery rack 20b is used for receiving and carrying the undercharged electric power battery 30b from the buffer lifting platform 102b and has a charging function.

EXAMPLE seven

As shown in fig. 1 to 9, in the present embodiment, one side of the lifting frame 101 faces the power exchanging platform, the fire box 50 is disposed on the corresponding side, and the first battery rack 20a and the second battery rack 20b are disposed on the other two sides of the lifting frame 101.

Preferably, in the present embodiment, the first bearing parts 1021 are arranged on both sides of the lifting platform 102, and the first transmission roller sets 1011 thereon perform transmission of the power battery 30 between the battery rack 20 and the lifting platform 102. The second bearing part 1022 is disposed in the middle of the bearing surface of the lifting platform 102, and is of a liftable structure, and the second transmission roller set 1012 thereon transmits the power battery 30 among the power exchanging platform, the lifting platform 102 and the fire box 50.

In this embodiment, when the second supporting portion 1022 is lifted, the supporting surface of the second transmission roller set 1012 is slightly higher than the supporting surface of the first transmission roller set 1011, so that the transmission of the power battery 30 by the second transmission roller set 1012 is not affected by the first transmission roller set 1011. When the second bearing part 1022 descends, the bearing surface of the second transmission roller set 1012 is slightly lower than that of the first transmission roller set 1011, so that the transmission of the power battery 30 by the first transmission roller set 1011 is not affected by the second transmission roller set 1012, and the smoothness of the transmission process is improved.

In this embodiment, the second supporting portion 1022 can be lifted and lowered by using a motor, an electric cylinder, an air cylinder, etc. as a driving force and using a vertical slide rail, a cam mechanism, a rigid chain, a lead screw, a gear, etc. as a transmission device.

In this embodiment, the lifting platform 102 is disposed in the lifting frame 101 in a lifting manner, the lifting platform 102 includes a transfer lifting platform 102a and a buffering lifting platform 102b, the transfer lifting platform 102a and the buffering lifting platform 102b are parallel to each other and are disposed at an interval from top to bottom, and a height difference between the transfer lifting platform 102a and the buffering lifting platform 102b is at least greater than a height of the power battery 30.

Preferably, in this embodiment, the battery rack 20 has a multi-layer structure, the distance between two adjacent layers of the battery rack 20 is the same and at least greater than the height of the power battery, and the distance between two adjacent layers of the bearing surfaces of the battery rack 20 is the same as the distance between the bearing surfaces of the relay lifting platform 102a and the bearing surfaces of the buffer lifting platform 102 b. By setting the distance between two adjacent bearing surfaces of the battery racks 20 and the distance between the bearing surfaces of the transfer lifting table 102a and the buffer lifting table 102b to be the same, when the transfer lifting table 102a receives a full battery on any layer of the battery racks 20, the buffer lifting table 102b can convey a deficient battery on the transfer lifting table to the battery rack 20 of the corresponding layer, so that the work efficiency of the electricity transfer device is improved.

Preferably, in this embodiment, the first battery rack 20a and the second battery rack 20b have the same number of layers, and the bearing surfaces of the layers correspond to each other one by one. The first battery rack 20a is used for placing the full-electric-power battery 30a and transmitting the full-electric-power battery 30a to the transfer lifting platform 102a, and the second battery rack 20b is used for receiving and bearing the insufficient-electric-power battery 30b from the buffer lifting platform 102b and has a charging function. The working mode of the battery rack 20 is increased, and meanwhile, the capacity of the battery of the power conversion transfer device is expanded.

In this embodiment, through set up fire hose 50 in the side that corresponds of trading electric platform, can trade the thermal runaway power battery 30 of electric in-process and carry out rapid processing, improved the security that trades the electric process.

As shown in fig. 7 to 9, the process of using the present invention is as follows: (1) when the vehicle starts to switch the battery, the lifting platform 102 is lifted to a proper position, the switching station control system sends a command to the proper position, and the transfer lifting platform 102a transmits the full-electric-power battery 30a on the first battery rack 20a to the transfer lifting platform 102a through the first transmission roller set 1011; (2) after the power battery 30 is taken out, the lifting platform 102 descends to a connection position, at this time, the second bearing part 1022 on the buffer lifting platform 102b ascends, and the power battery 30b with insufficient voltage is transmitted to the buffer lifting platform 102b through the battery replacing mechanism 40 and the second transmission roller group 1012; (3) after the electric power-deficient battery 30b is transferred to the position, the lifting platform 102 is lowered to the transfer position again, at this time, the second bearing part 1022 on the transfer lifting platform 102a is lifted, and the full-electric power battery 30a is transferred to the electricity conversion mechanism 40; (4) the elevating platform 102 is raised to align the buffer elevating platform 102b with the empty floor on the second battery rack 20b, the second bearing part 1022 on the buffer elevating platform 102b is lowered, and the first transmission roller set 1011 on the buffer elevating platform 102b transmits the electric power loss battery 30b to the second battery rack 20b for charging.

In this embodiment, if the power battery 30 on the battery rack 20 is out of control due to heat, the lifting platform 102 is lifted to a proper position, the transfer lifting platform 102a transfers the power battery 30 on the battery rack 20 to the transfer lifting platform 102a through the first transfer roller set 1011, and then the second carrying part 1022 on the transfer lifting platform 102a is lifted, and the second transfer roller set 1012 on the second carrying part 1022 transfers the power battery 30 out of control due to heat to the fire box 50.

If the power battery 30 on the transfer electric vehicle finds thermal runaway when the transfer is started, the transfer lifting platform 102a is lifted to a proper position, the power-shortage power battery 30b is transmitted to the transfer lifting platform 102a through the transfer mechanism 40, and then the second transmission roller set 1012 on the transfer lifting platform 102a is lifted to transmit the thermal runaway power battery 30 to the fire box 50.
