The fire-fighting cabin 6 is provided on the side of the battery swap station body 7 away from the doorway, thereby avoiding the battery swap channel and not affecting the battery swapping task of the battery swap station.

[0126] In some possible implementation schemes, the transfer device has a walking mechanism and can move along the extension direction of the battery swap station body 7. The transfer device can extend out of the battery swap door opening 71 or retract from the battery swap door opening 71 to perform the battery swap task.

[0127] In this embodiment, the transfer device is also used for battery replacement, and the battery replacement station does not need to be equipped with a separate battery replacement robot 9.

[0136] See also Figures 8 to 17 As shown, the fourth embodiment of the present application further illustrates the battery swap station in detail, which includes: a battery swap station body 7, a fire-fighting compartment 6, a transfer device, a temporary storage seat 2 and a plurality of battery trays 10. The battery swap station body 7 has a cavity, and the temporary storage seat 2 and each of the battery trays 10 are arranged in the cavity. The temporary storage seat 2 and each of the battery trays 10 are arranged in sequence along the extension direction of the battery swap station body 7.

The transfer device and the temporary storage seat 2 are coordinated in transmission, and the transfer device can drive the temporary storage seat 2 to slide out of the cavity and move into the fire-fighting compartment 6.

[0137] The temporary storage seat 2 of the present application is used as a temporary intermediate transfer battery base on the one hand, and as a fire transport vehicle on the other hand. The temporary storage seat 2 set in the middle of the battery swap station is used as a fire waiting area, and no separate space is reserved in the main body 7 of the battery swap station.

[0138] The fire fighting chamber 6 is provided outside the main body 7 of the battery swap station of the present application. The main body 7 of the battery swap station and the fire fighting chamber 6 are isolated to form an independent fire fighting space, which will not affect other battery boxes in the main body 7 of the battery swap station. A transfer device is provided on the main body 7 of the battery swap station, which can directly transfer the temporary storage seat 2 and the battery box with thermal runaway thereon to the fire fighting chamber 6 for fire fighting treatment, thereby improving the efficiency of fire fighting treatment, achieving the effect of rapid fire fighting, and improving the safety of the battery swap station.

[0139] The main body 7 of the battery swap station is provided with an escape hole for allowing the temporary storage seat 2 and the battery box to enter and exit the main body 7 of the battery swap station through the escape hole.

The battery swap robot 9 may be arranged in the upper cavity, and the battery swap door 71 is connected to the upper cavity. The escape hole is connected to the lower cavity, and the transfer device is arranged in the lower cavity. The transfer device can directly drive the temporary storage seat 2 and the battery box located on the temporary storage seat 2 to extend out of the lower cavity, and finally be sent into the fire compartment 6.

[0140] In some possible implementations, see Fig.11As shown, the transfer device includes a first lifting mechanism 1 and a horizontal transfer mechanism 3. The temporary storage seat 2 is supported by the first lifting mechanism 1. The first lifting mechanism 1 can drive the temporary storage seat 2 to move up and down to adjust the temporary storage seat 2 to the first station or the second station. When the temporary storage seat 2 is located at the first station, the temporary storage seat 2 and each of the battery bases 10 are located at the same height. At this time, if the battery box is placed on the temporary storage seat 2, the top of the battery box is higher than the upper edge of the escape opening, and the battery box is difficult to be directly moved horizontally through the escape opening. In order to solve this technical problem, when the temporary storage seat 2 is located at the second station, the temporary storage seat 2 is located lower than each of the battery bases 10, wherein, when the temporary storage seat 2 is located at the second station, the top of the battery box placed on the temporary storage seat 2 is lower than the upper edge of the escape opening, and the horizontal transfer mechanism 3 can cooperate with the temporary storage seat 2 to drive the temporary storage seat 2 to slide away from the cavity and move into the fire fighting chamber 6. It should be noted that the battery box with thermal runaway can be grabbed by the battery replacement robot 9 and placed on the temporary storage seat 2.

The opposite ends of the first connecting rod 13 and the second connecting rod 14 are hinged, and the other ends of the first connecting rod 13 and the second connecting rod 14 are respectively hinged to the lifting seat 12 and the battery swap station body 7. The two ends of the telescopic member 15 are respectively hinged to the second connecting rod 14 and the battery swap station body 7. The telescopic member 15 can telescope and drive the first connecting rod 13 and the second connecting rod 14 to deform, so as to push the lifting seat 12 to move up and down.

[0144] The first lifting mechanism 1 is located on both sides of the temporary storage seat 2, and two lifting assemblies are respectively provided. The second connecting rods 14 of the two lifting assemblies on the same side of the temporary storage seat 2 are connected by a synchronous connecting rod 16, and the second connecting rod 14 and the synchronous connecting rod 16 are hinged. Among them, the synchronous connecting rod 16, the first connecting rod 13 and the second connecting rod 14 can be connected by the same pin shaft. A parallelogram mechanism is formed between the synchronous connecting rod 16, the two second connecting rods 14 and the battery swap station body 7. The bottom of the telescopic member 15 can be hinged to the bottom frame of the battery swap station body 7. No matter how much the telescopic member 15 is extended, the top synchronous connecting rod 16 always remains parallel to the bottom frame of the battery swap station body 7. The synchronous connecting rod 16 can make the two lifting assemblies rise and fall synchronously. The first lifting mechanism 1 provided in the embodiment of the present application effectively solves the problem that the battery pack is supported when it is placed and can be quickly and vertically lowered, and can be effectively and stably lowered.

The door driving mechanism and the chamber door 5 are transmission-connected to drive the chamber door 5 to close or open the chamber opening. A chamber door 5 for isolation is provided between the main body 7 of the battery swap station and the fire-fighting chamber 6. After the thermal runaway battery is loaded into the fire-fighting chamber 6, the chamber door 5 can be quickly closed to ensure the isolation of the fire and smoke and avoid harming other battery packs.

[0153] Embodiment 5

[0154] The present application provides a control method for a battery swap station in Embodiment 3 and Embodiment 4, including:

[0155] Step S1, the battery swap station receives a fire command;

[0156] Temperature and smoke sensors are installed in the main body of the battery swap station, and sensors are installed in the battery box. When certain sensors sense abnormalities, they will trigger the sending of fire-fighting instructions to the control end of the battery swap station, causing the battery swap station to start the fire-fighting extinguishing procedure.

[0157] Step S2, the battery swap station controls the battery swap robot 9 to transfer the battery box with thermal runaway to the temporary storage seat 2;

[0158] In this step, the battery swap robot 9 walks to the thermal runaway battery box and grabs the thermal runaway battery box.

[0161] Step S3 includes:

[0162] Step S31, the first lifting mechanism 1 of the transfer device drives the temporary storage seat 2 to descend to the second station;

[0163] In this step, when the temporary storage seat 2 senses that a thermal runaway battery pack has fallen into place, the first lifting mechanism 1 is immediately started to lower the temporary storage seat 2 and the thermal runaway battery box from a high position to the guide rail 4 at the bottom.

[0164] When the battery-exchange robot 9 lifts the battery box with thermal runaway to the temporary storage seat 2, the telescopic member 15 (lifting cylinder) retracts, and the support plate 1211 on the lifting seat 12 supports the support foot 23 of the temporary storage seat 2, and then descends until the second track matching wheel 24 on the temporary storage seat 2 falls on the guide rail 4. At this time, the temporary storage seat 2 is separated from the first lifting mechanism 1, and the sensor 18 set on the longitudinal guide rail 11 senses the corresponding information, triggering the stop of the telescopic member 15 to retract.

[0165] Step S32 , the horizontal transfer mechanism 3 of the transfer device drives the temporary storage seat 2 to slide out of the cavity and move into the fire fighting chamber 6 .

[0166] In this step, while the temporary storage seat 2 is lowered onto the guide rail 4, the horizontal transfer mechanism 3 is started, and the push-pull trolley 31 is driven by the traction chain (a specific form of the bar body 35). The push-pull trolley 31 hooks the temporary storage seat 2 and moves along the guide rail 4, and the battery pack with thermal runaway is moved from the battery swap station body 7 to the fire fighting chamber 6. Then, the chamber door 5 is controlled to be closed to isolate the battery swap station body 7 and the fire fighting chamber 6, and the fire extinguisher system is started in the fire fighting chamber 6 to achieve the effect of rapid fire extinguishing.
