[0073] See also Figures 1 to 10As shown, an embodiment of the present application provides a battery swap station, including: a battery swap station body 7, a fire fighting compartment 6 and a fire fighting transfer device. The battery swap station body 7 has a cavity, in which a battery box is accommodated, the fire fighting compartment 6 is located outside the cavity, and the fire fighting transfer device is at least partially arranged in the cavity, and the fire fighting transfer device can drive the battery box with thermal runaway to extend out of the cavity, so as to transfer the battery box with thermal runaway to the fire fighting compartment 6.

[0074] The present application provides a fire fighting chamber 6 outside the main body 7 of the battery swap station. 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 fire fighting transfer device is provided on the main body 7 of the battery swap station, which can directly transfer the battery box with thermal runaway 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.

[0075] In some possible implementations, the fire fighting compartment 6 is arranged on one side of the battery swap station body 7 along the width direction, and the fire fighting transfer device can be moved along the width direction of the battery swap station body 7 and extend out of the cavity to transfer the battery box with thermal runaway to the fire fighting compartment 6.

[0076] In this embodiment, the fire-fighting cabin 6 is located on one side of the battery swap station body 7 along the width direction, which will not extend the length of the battery swap station. The fire-fighting cabin 6 is located on one side of the outside of the battery swap station body 7 along the width direction, which can shorten the stroke of the fire-fighting transfer device and facilitate the fire-fighting transfer device to transfer the battery box directly to the fire-fighting cabin 6.

[0077] In some possible implementations, see Figure 1 and Figure 2 As shown, the battery swap station body 7 has a battery swap door hole 71 connected to the cavity on one side along the width direction, and the fire fighting cabin 6 is arranged on the other side of the battery swap station body 7 along the width direction.

[0078] One side of the battery swap doorway 71 of the battery swap station body 7 is provided as a battery swap channel, which is the area for battery swapping of electric vehicles. 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.

[0079] In some possible implementation schemes, the fire-fighting transfer device has a walking mechanism and can move along the extension direction of the battery swap station body 7. The fire-fighting transfer device can extend out of the battery swap door opening 71 or retract from the battery swap door opening 71 to perform battery swap tasks.

[0080] In this embodiment, the fire-fighting 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. At this time, the specific structure of the fire-fighting transfer device can refer to the structure of the battery replacement robot 9 provided in the prior art, and can include a telescopic arm and a sling arranged on the telescopic arm. The telescopic arm can drive the sling to extend out of the battery replacement door hole 71 or retract from the battery replacement door hole 71 to perform the battery replacement task.

[0081] In some possible solutions, the battery swap station body 7 is located on a supporting surface, the fire-fighting chamber 6 is located on the supporting surface, or the fire-fighting chamber 6 is at least partially located at the bottom of the supporting surface. The supporting surface may be the ground, and the battery swap station body 7 and the fire-fighting chamber 6 may be located on the ground. A pit is excavated on the supporting surface, and the fire-fighting chamber 6 may also be arranged in the pit. The fire-fighting transfer device can directly push the thermal runaway battery box out of the battery swap station body 7 and place it in the pit. When the battery box is transferred to the fire-fighting chamber 6, the fire extinguisher system in the fire-fighting chamber 6 is activated to perform a rapid fire-fighting action.

[0082] In some possible solutions, a fire exit is set on the side of the battery swap station body 7 away from the battery swap door opening 71 to avoid the fire transfer device and the thermal runaway battery box. The fire transfer device can drive the thermal runaway battery box to extend out of the fire exit and enter the fire compartment 6.

[0083] The battery swap station body 7 may include an upper cavity and a lower cavity. A transfer seat 2 and a plurality of battery seats 10 are arranged in the lower cavity. The battery seat 10 is used to place the battery box, and the transfer seat 2 is used to temporarily store the battery box. The battery swap robot 9 may be arranged in the upper cavity, and the battery swap door hole 71 is connected to the upper cavity. The upper cavity and the lower cavity are connected. The fire outlet is connected to the lower cavity, and the fire transfer device is arranged in the lower cavity. The fire transfer device can directly drive the transfer seat 2 and the battery box located on the transfer seat 2 to extend out of the lower cavity, and finally send them into the fire compartment 6.

[0084] In some possible implementations, the fire fighting chamber 6 has a fire fighting cavity and a hatch connected to the fire fighting cavity, the hatch is located on the side of the fire fighting chamber 6 and faces the battery swap station body 7, or the hatch is located at the top of the fire fighting chamber 6. When the hatch is located on the side of the fire fighting chamber 6, the fire fighting transfer device can directly push the transfer seat 2 and the battery box located on the transfer seat 2 into the fire fighting chamber 6. When the hatch is located at the top of the fire fighting chamber 6, the structure of the fire fighting transfer device is similar to that of a conventional battery swap robot 9, and the thermal runaway battery box can be grabbed by a hoist, and then the telescopic arm assembly of the fire fighting transfer device drives the hoist and the thermal runaway battery box to extend out of the battery swap station body 7 and moves the hoist to the top of the hatch, and then the hoist is controlled to lower the battery box to place the battery box in the fire fighting chamber 6.

[0085] Specifically, the fire transfer device has a horizontal telescopic part and a vertical lifting part arranged on the horizontal telescopic part. The horizontal telescopic part can be the telescopic arm mentioned above. The vertical lifting part can grab or release the battery box with thermal runaway. The vertical lifting part includes a hoist. The hoist can specifically include a winch and a battery gripper. The winch is wound with a lifting rope, and the lifting rope is connected to the battery gripper. The horizontal telescopic part can drive the vertical lifting part to extend out of the cavity of the battery swap station body 7. The vertical lifting part can drive the battery box down to the hatch at the top of the fire compartment 6 and unload it into the fire compartment.

[0086] In some possible implementations, the battery swap station includes a battery swap robot 9, which is disposed in the cavity and has a telescopic arm that can extend or retract into the cavity to perform the battery swap operation. In this implementation, the battery swap station is equipped with both a battery swap robot 9 and a firefighting transfer device, which is only used to transfer the thermal runaway battery box to the firefighting compartment 6, and is not used to perform the battery swap operation.

[0087] In some possible implementations, the battery swap station includes a canopy 8, which is arranged on one side of the battery swap station body 7 along the width direction, forming a battery swap channel between the canopy 8 and the battery swap station body 7, and the fire cabin 6 is located on the side of the battery swap station body 7 away from the battery swap channel. Embodiment 2

[0088] Embodiment 2 of the present application further describes the battery swap station in detail, which includes: a battery swap station body 7, a fire fighting compartment 6, a fire fighting transfer device, a transfer seat 2 and a plurality of battery seats 10. The battery swap station body 7 has a cavity, and the transfer seat 2 and each of the battery seats 10 are arranged in the cavity. The transfer seat 2 and each of the battery seats 10 are arranged in sequence along the extension direction of the battery swap station body 7. The fire fighting compartment 6 is located outside the cavity, and the fire fighting transfer is at least partially arranged in the cavity. The fire fighting transfer device and the transfer seat 2 are coordinated in transmission, and the fire fighting transfer device can drive the transfer seat 2 to slide out of the cavity and move into the fire fighting compartment 6.

[0089] The transfer seat 2 of the present application is used as a temporary transfer battery base on one hand, and as a fire transport vehicle on the other hand. The transfer seat 2 set in the middle of the battery swap station is used as a temporary waiting area for firefighting, and no separate space is required in the main body 7 of the battery swap station.

[0090] 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 fire fighting transfer device is provided on the main body 7 of the battery swap station, which can directly transfer the transfer 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.

[0091] A fire exit is provided on the main body 7 of the battery swap station, which is used to prevent the transfer seat 2 and the battery box from entering and exiting the main body 7 of the battery swap station through the fire exit. The main body 7 of the battery swap station may include an upper cavity and a lower cavity. The transfer seat 2 and a plurality of battery seats 10 are arranged in the lower cavity. The battery seat 10 is used to place the battery box, and the transfer seat 2 is used to temporarily store the battery box. 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 fire exit is connected to the lower cavity, and the fire transfer device is arranged in the lower cavity. The fire transfer device can directly drive the transfer seat 2 and the battery box located on the transfer seat 2 to extend out of the lower cavity, and finally be sent into the fire compartment 6.

[0092] In some possible implementations, see Figure 4 As shown, the fire transfer device includes a lifting mechanism 1 and a horizontal transfer mechanism 3. The transfer seat 2 is supported by the lifting mechanism 1. The lifting mechanism 1 can drive the transfer seat 2 to move up and down to adjust the transfer seat 2 to the first station or the second station. When the transfer seat 2 is located at the first station, the transfer seat 2 and each of the battery seats 10 are located at the same height. At this time, if the battery box is placed on the transfer seat 2, the top of the battery box is higher than the upper edge of the fire outlet, and the battery box is difficult to be directly moved horizontally through the fire outlet. In order to solve this technical problem, when the transfer seat 2 is located at the second station, the transfer seat 2 is located lower than each of the battery seats 10, wherein, when the transfer seat 2 is located at the second station, the top of the battery box placed on the transfer seat 2 is lower than the upper edge of the fire outlet, and the horizontal transfer mechanism 3 can cooperate with the transfer seat 2 to drive the transfer seat 2 to slide out of the cavity and move into the fire compartment 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 transfer seat 2.

[0093] In some possible implementations, see Figures 5 to 10 As shown, the battery swap station includes a fixed frame, which is connected to the battery swap station body 7, and the fixed frame has a longitudinal guide rail 11. The lifting mechanism 1 includes a lifting seat 12 and a lifting assembly. The lifting seat 12 is slidably connected to the longitudinal guide rail 11, and the transfer seat 2 is supported on the lifting seat 12. The lifting assembly and the lifting seat 12 are transmission-connected to drive the lifting seat 12 to slide along the longitudinal guide rail 11 to drive the transfer seat 2 to move up and down.

[0094] Among them, see Figures 5 to 8 As shown, the lifting seat 12 has a main board 121, a support plate 1211 and a plurality of pulleys 122, each of the pulleys 122 is arranged on one side of the main board 121 along the thickness direction, each of the pulleys 122 is respectively located on both sides of the longitudinal guide rail 11, and is in rolling contact with the longitudinal guide rail 11, the support plate 1211 is located on the other side of the main board 121 along the thickness direction, the transfer seat 2 is supported on the support plate 1211, and the lifting assembly is transmission-connected to the main board 121.

[0095] In some possible implementations, see Figure 5 and Figure 6 As shown, the lifting assembly includes a telescopic component 15, a first connecting rod 13 and a second connecting rod 14. 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 component 15 are respectively hinged to the second connecting rod 14 and the battery swap station body 7. The telescopic component 15 can drive the first connecting rod 13 and the second connecting rod 14 to deform to push the lifting seat 12 to move up and down.

[0096] The lifting mechanism 1 is located on both sides of the transfer seat 2 and is respectively provided with two lifting assemblies. The second connecting rods 14 of the two lifting assemblies on the same side of the transfer 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 component 15 can be hinged to the bottom frame of the battery swap station body 7. No matter how much the telescopic component 15 is telescopic, 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 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.

[0097] Furthermore, the lifting mechanism 1 also includes a stabilizing beam 17, which is respectively connected to two lifting seats 12 at opposite positions on both sides of the transfer seat 2 along the width direction, that is, the main board 121 of the lifting seat 12, so that the lifting components and each lifting seat 12 on both sides of the transfer seat can be lifted and lowered synchronously, thereby realizing the smooth lifting or lowering of the transfer seat 2 and the thermal runaway battery box on the transfer seat 2.

[0098] In some possible implementations, see Fig.10As shown, the transfer seat 2 has a seat body 21 and a plurality of columns 22 arranged on the edge of the seat body 21 , and a supporting foot 23 is arranged at the end of each of the columns 22 , and each of the supporting feet 23 is supported on a corresponding lifting seat 12 .

[0099] See also Fig. 9 and Fig.10 As shown, the horizontal transfer mechanism 3 includes a push-pull trolley 31, a transmission assembly and a driving component 36. The transmission assembly and the driving component 36 are both arranged on the battery swap station body 7. When the transfer seat 2 is located under the second workstation, the transfer seat 2 and the push-pull trolley 31 are coordinated in transmission, the driving component 36 and the transmission assembly are coordinated in transmission, and the transmission assembly and the push-pull trolley are coordinated in transmission to drive the push-pull trolley 31 to push the transfer seat 2 to slide out of the cavity and move into the fire compartment 6.

[0100] The push-pull trolley 31 has a main beam 311 and thrust plates 312 located at both ends of the main beam 311. During the movement of the push-pull trolley 31 toward the fire compartment 6, one thrust plate 312 pushes the transfer seat 2 to move toward the fire compartment 6. During the movement of the push-pull trolley 31 toward the battery swap station body 7, the other thrust plate 312 pushes the transfer seat 2 to move toward the cavity.

Example

[0105] Embodiment 3 of the present application provides a fire protection method for a battery swap station, including:

[0106] Step S1, the battery swap station receives a fire command;

[0107] Temperature and smoke sensors are installed in the battery swap station itself, and sensors are installed in the battery box. When certain sensors sense an abnormality, they will trigger a fire-fighting command to be sent to the control end of the battery swap station, causing the battery swap station to start the fire-fighting procedure.

[0108] Step S2, the battery swap station controls the battery swap robot 9 to transfer the battery box with thermal runaway to the transfer seat 2;

[0109] In this step, the battery swap robot 9 walks to the thermal runaway battery box and grabs the thermal runaway battery box. At the same time, the door 5 of the fire fighting compartment 6 is opened, and the battery swap robot 9 places the thermal runaway battery box on the transfer seat 2.

[0110] Step S3: The battery swap station controls the fire transfer device to drive the transfer seat 2 to slide out of the cavity and move into the fire compartment 6.

[0111] Optionally, in step S2, the transfer seat 2 is located at the first station;

[0112] Step S3 includes:

[0113] Step S31, the lifting mechanism 1 of the fire transfer device drives the transfer seat 2 to descend to the second station;

[0114] In this step, when the transfer seat 2 senses that a thermal runaway battery pack has fallen into place, the lifting mechanism 1 is immediately started to lower the transfer seat 2 and the thermal runaway battery box from a high position to the guide rail 4 at the bottom.

[0115] When the battery-exchange robot 9 lifts the battery box with thermal runaway to the transfer seat 2, the telescopic component 15 (lifting cylinder) retracts, and the support plate 1211 on the lifting seat 12 supports the support foot 23 of the transfer seat 2, and then descends until the second track matching wheel 24 on the transfer seat 2 falls on the guide rail 4. At this time, the transfer seat 2 is separated from the lifting mechanism 1, and the sensor 18 set on the longitudinal guide rail 11 senses the corresponding information, triggering the stop of the telescopic component 15 retraction.

[0116] Step S32 , the horizontal transfer mechanism 3 of the fire transfer device drives the transfer seat 2 to slide out of the cavity and move into the fire compartment 6 .

[0117] In this step, while the transfer 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 transfer seat 2 and moves along the guide rail 4 to move the battery pack with thermal runaway 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.
