The battery swap station comprises a battery swap platform, a charging cabin and a shuttle vehicle. The electric vehicle drives to the battery swap platform. The shuttle vehicle dismounts the depleted battery pack on the electric vehicle. The depleted battery pack is transported to the charging cabin by the shuttle vehicle for charging. The shuttle vehicle transports the fully charged battery pack in the charging cabin to the battery swap platform and installs it on the electric vehicle, thereby completing the battery swap operation of the electric vehicle.

[0068] As Figures 1 to 6 shown, the charging cabin comprises a cabin body 1 and a first battery rack 2. The cabin body 1 has a battery rack area 12, an elevator area 13 and a shuttle vehicle area 11. The elevator area 13 is located between the battery rack area 12 and the shuttle vehicle area 11. The first battery rack 2 is arranged in the shuttle vehicle area 11. An avoidance space 111 for the shuttle vehicle to pass through is formed between the bottom of the first battery rack 2 and the bottom of the cabin body 1. The charging cabin further comprises an elevator arranged in the elevator area 13. The elevator is used to take and place the battery pack on the battery rack area 12 and the first battery rack 2 on both sides. The shuttle vehicle drives between the avoidance space 111 of the shuttle vehicle area 11 and the battery swap platform. The first battery rack 2 is arranged above the shuttle vehicle area 11, thereby making full use of the space above the shuttle vehicle area 11 for charging the battery pack, effectively increasing the number of charging batteries in the charging cabin, and making the structure more compact and occupying less space as a whole.

[0069] As Figure 2 , Figure 4 and Figure 5 shown, the first battery rack 2 comprises a first rack body 21, a plurality of first charging positions 22, a plurality of first electric connectors 23, a plurality of mounting seats 24 and a plurality of rack height seats 25. The plurality of mounting seats 24, the plurality of rack height seats 25, the plurality of first electric connectors 23 and the plurality of first charging positions 22 correspond to each other. The plurality of first charging positions 22 are arranged in the first rack body 21 in the height direction. The mounting seat 24, the rack height seat 25 and the first electric connector 23 are arranged at one end of the first rack body 21 close to the elevator area 13. The mounting seat 24 is connected to the first rack body 21. The upper and lower ends of the rack height seat 25 are connected to the mounting seat 24 and the first electric connector 23 respectively, so that the first electric connector 23 is elevated to avoid the extension mechanism of the elevator.

[0070] When the battery pack needs to be placed on the first battery rack 2, the elevator will control the battery pack to rise and be higher than the first electric connector 23, then the extension mechanism of the elevator extends into the first charging position 22, so that the battery pack on the extension mechanism also extends into the first charging position 22, then the extension mechanism of the elevator moves downward, so that the battery pack on the extension mechanism will be placed in the first charging position 22, and finally the extension mechanism retracts inwardly to the outside of the first battery rack 2, and the elevator returns to the initial state, thereby completing the placement of the battery pack on the first battery rack 2; conversely, the battery pack on the first battery rack 2 is taken out.

[0071] The first electric connector 23 is arranged between the mounting seat 24 and the first frame body 21 and is used to elevate the first electric connector 23 upward, so that the extension mechanism can extend into the first charging position 22 to take out the battery pack and retract into the first charging position 22 to place the battery pack. By arranging the first electric connector 23 at one end of the first frame body 21 close to the elevator area 13, the battery rack area 12 and the battery pack on the first battery rack 2 are arranged at the same position, that is, the electric connectors on the battery racks on both sides of the elevator are arranged at the same direction position, and the extension mechanism on the elevator can move toward any side to realize the taking and placing of the battery pack, thereby realizing that the rotating mechanism on the elevator is not required to rotate and adjust the direction of the extension mechanism of the elevator, the overall structure is simple, and the cost is low. At the same time, the extension mechanism of the elevator does not need to rotate and adjust the direction when taking and placing the battery pack, so that the efficiency of replacing the battery pack is effectively improved.

[0072] The elevation seat 25, the mounting seat 24 and the first frame body 21 form an avoidance groove 26 for avoiding the extension mechanism of the elevator. When the elevator needs to place the battery pack on the first battery rack 2, the extension mechanism of the elevator and the battery pack extend into the first charging position 22 together, then the extension mechanism of the elevator moves downward into the avoidance groove 26, at the same time, the battery pack on the extension mechanism is placed on the first charging position 22, finally the extension mechanism retracts inwardly to the outside of the first battery rack 2, and the elevator returns to the initial state, thereby completing the placement of the battery pack on the first battery rack 2. When the elevator needs to take out the battery pack placed on the first battery rack 2, the extension mechanism of the elevator extends into the first battery rack 2 through the avoidance groove 26, then the extension mechanism of the elevator moves upward and lifts the battery pack on the first charging position 22 upward to the extension mechanism, the extension mechanism of the elevator and the battery pack rise and are higher than the first electric connector 23, finally the extension mechanism retracts inwardly to the outside of the first battery rack 2 and drives the battery pack, thereby taking out the battery pack on the first battery rack 2 and placing it on the elevator, thereby completing the taking out of the battery pack. The avoidance groove 26 is used to avoid the extension mechanism of the elevator, so that the elevator and the first battery rack 2 will not interfere with each other, and the taking and placing of the battery pack in the first battery rack 2 are guaranteed.

[0073] The heightening seat 25 is arranged in the middle region of the mounting seat 24, and the two sides of the heightening seat 25 are both formed with the avoiding grooves 26 between the mounting seat 24 and the first frame body 21. The extension mechanism of the lifting machine is used for taking and placing the battery pack through the avoiding grooves 26 at the two sides of the heightening seat 25, so that the two side forces of the battery pack act on the extension mechanism of the lifting machine, and the battery pack is stably placed on the extension mechanism, and the stability of taking and placing the battery pack is high.

[0074] The mounting seat 24 is arranged below the corresponding first charging position 22, so that the first electric connector 23 mounted on the heightening seat 25 is used for mutually plugging with the battery pack in the first charging position 22. By arranging the mounting seat 24 downward, and then arranging the first electric connector 23 upward by the heightening seat 25, the mutual plugging of the first electric connector 23 and the electric connector of the battery pack in the first charging position 22 is guaranteed, at the same time, the downward arrangement of the mounting seat 24 can play an avoiding role with the extension mechanism of the lifting machine, and the structure is more compact in the height direction, and more first charging positions 22 on the first battery rack 2 can be arranged for charging more battery packs.

After taking out the battery pack, the two extension mechanisms move downward, place the full battery pack on the shuttle vehicle, and then the shuttle vehicle installs the full battery pack on the electric vehicle, thereby completing the battery replacement operation. The elevator can take and place the battery pack at the same time through the two extension mechanisms, effectively shortening the battery replacement time, thereby further improving the battery replacement efficiency.

[0084] Embodiment 2

[0085] The utility model embodiment further discloses a battery replacement control method, which utilizes the charging cabin as described above.

By controlling the extension mechanism to ascend and be higher than the first electric connector 23, the extension mechanism and the battery pack thereon can be prevented from interfering with the first electric connector 23 when the battery pack is placed, so that the extension mechanism and the battery pack thereon can extend outward into the first charging cabin position 22 together. By controlling the extension mechanism to descend, the battery pack on the extension mechanism is placed in the first charging cabin position 22. Finally, the extension mechanism retracts inward to outside the first battery rack 2, and the elevator returns to the initial state, so that the battery pack is placed in the first charging cabin position 22 and the battery pack is charged. By avoiding the first electric connector 23 with the extension mechanism on the elevator, the battery pack can be placed in the first charging cabin position 22 for charging, so that a rotating mechanism for rotating and adjusting the direction of the extension mechanism of the elevator is not needed, and the overall structure of the elevator is simple and the cost is low. At the same time, the extension mechanism of the elevator does not need to rotate and adjust the direction when taking and placing the battery pack, so that the battery pack replacement efficiency is effectively improved.

[0086] The battery replacing control method further comprises the following steps: controlling the extension mechanism to descend and be lower than the first electric connector 23; controlling the extension mechanism to extend outward into the first charging position 22; controlling the extension mechanism to ascend so that the battery pack in the first charging position 22 is placed on the extension mechanism and the extension mechanism is higher than the first electric connector 23; and controlling the extension mechanism to retract inward out of the first battery rack 2. By controlling the extension mechanism to descend and be lower than the first electric connector 23, interference between the extension mechanism and the first electric connector 23 when the battery pack is taken out is effectively avoided, so that the extension mechanism extends outward into the first charging position 22. By controlling the extension mechanism to ascend, the battery pack on the first charging position 22 is placed on the extension mechanism, and the extension mechanism is controlled to ascend to a height higher than the first electric connector 23, so that when the extension mechanism retracts inward out of the first battery rack 2, the battery pack is taken out and interference with the first electric connector 23 does not occur, thereby taking the battery pack on the first battery rack 2 out to the elevator. The elevator does not need to be provided with a rotating mechanism for rotating and adjusting the direction of the extension mechanism, so that the overall structure of the elevator is simple and the cost is low. At the same time, the extension mechanism of the elevator does not need to be rotated and adjusted in direction when taking and placing the battery pack, so that the battery pack replacing efficiency is effectively improved.

[0087] The elevator has two extension mechanisms distributed up and down and used for taking and placing the battery pack; the two extension mechanisms respectively take out the full battery pack in the transfer position 27 and the depleted battery pack on the shuttle vehicle in the shuttle vehicle area 11 at the same time. The two extension mechanisms respectively take out the full battery pack in the transfer position 27 and the depleted battery pack on the shuttle vehicle in the shuttle vehicle area 11 at the same time, and then move downward to place the full battery pack on the shuttle vehicle, and then the shuttle vehicle installs the full battery pack on the electric vehicle, thereby completing the battery replacing operation.
