Description

Technical Field

[0001] This utility model relates to the field of battery swapping technology, and more specifically, to a battery swapping station with a fire-fighting compartment. Background Technology

[0002] With the development of new energy technologies, the demand for battery swapping stations is increasing daily. Battery swapping stations come in various forms. The battery boxes inside the swapping station enclosure need to be charged or discharged, inevitably causing the temperature inside the battery box to rise. With numerous high-voltage and low-voltage lines inside the battery box, overheating or short-circuiting and combustion are unavoidable. If a burning battery box is not dealt with promptly, it will affect other battery boxes within the swapping station. Some swapping stations have a battery compartment and a fire suppression compartment inside the enclosure. The battery compartment houses the battery boxes, and the fire suppression compartment and battery compartment are located in the same enclosure. When a thermally runaway battery box is placed in the fire suppression compartment, heat will be conducted to one side of the battery compartment, affecting other normal battery boxes inside the enclosure.

[0045] Example 1

[0046] See Figures 1 to 10As shown in the figure, this application embodiment provides a battery swapping station with a fire-fighting compartment, including: a battery swapping station body 7, a fire-fighting compartment 6, and a fire-fighting transfer device. The battery swapping station body 7 has a cavity, the cavity containing a battery box, the fire-fighting compartment 6 being located outside the cavity, and the fire-fighting transfer device being at least partially disposed within the cavity. The fire-fighting transfer device can drive a thermally runaway battery box out of the cavity to transfer the thermally runaway battery box into the fire-fighting compartment 6.

[0047] The battery swapping station main body 7 of this application is equipped with a fire-fighting compartment 6 outside. The battery swapping station main body 7 and the fire-fighting compartment 6 are isolated from each other, forming an independent fire-fighting space, which will not affect other battery boxes inside the battery swapping station main body 7. The battery swapping station main body 7 is equipped with a fire-fighting transfer device, which can directly transfer the thermally runaway battery box to the fire-fighting compartment 6 for fire-fighting treatment, improving fire-fighting efficiency, achieving rapid fire extinguishing effect, and improving the safety of the battery swapping station.

[0048] In some possible implementations, the fire compartment 6 is located on one side of the battery swapping station body 7 along the width direction, and the fire transfer device can move out of the cavity along the width direction of the battery swapping station body 7 to transfer the thermally runaway battery box to the fire compartment 6.

[0049] In this implementation plan, the fire compartment 6 is located on one side of the main body 7 of the battery swapping station along the width direction, which will not extend the length of the battery swapping station. The fire compartment 6 is located on the outside of the main body 7 of the battery swapping station along the width direction, which can reduce the travel distance of the fire transfer device and facilitate the fire transfer device to directly transfer the battery box into the fire compartment 6.

[0050] See some possible implementations. Figure 1 and Figure 2 As shown, the main body 7 of the power swapping station has a power swapping doorway 71 communicating with the cavity on one side along the width direction, and the fire compartment 6 is located on the other side along the width direction of the main body 7 of the power swapping station.

[0051] The battery swapping station body 7 has a battery swapping doorway 71 on one side, which is a battery swapping passage and an area for swapping batteries for electric vehicles. The fire compartment 6 is located on the side of the battery swapping station body 7 away from the doorway, thus avoiding the battery swapping passage and not affecting the battery swapping station's battery swapping tasks.

[0052] In some possible implementations, the fire transfer device has a walking mechanism that can move along the extension direction of the main body 7 of the battery swapping station, and the fire transfer device can extend out of the battery swapping doorway 71 or retract from the battery swapping doorway 71 to perform the battery swapping task.

[0053] In this implementation scheme, the fire transfer device also serves as a battery swapping station, eliminating the need for a separate battery swapping robot 9 at the battery swapping station. The specific structure of the fire transfer device can refer to the structure of the battery swapping robot 9 provided in the prior art, and may include a telescopic arm and a lifting device mounted on the telescopic arm. The telescopic arm can extend the lifting device out of the battery swapping portal 71 or retract it from the portal 71 to perform the battery swapping task.

[0054] In some possible configurations, the battery swapping station main body 7 is located on a supporting surface, and the fire-fighting compartment 6 is located on the supporting surface, or at least partially at the bottom of the supporting surface. The supporting surface can be the ground, and both the battery swapping station main body 7 and the fire-fighting compartment 6 can be located on the ground. A pit is excavated on the supporting surface, and the fire-fighting compartment 6 can also be placed in the pit. The fire-fighting transfer device can directly push the thermal runaway battery box out of the battery swapping station main body 7 and place it in the pit. When the battery box is transferred into the fire-fighting compartment 6, the fire extinguishing system in the fire-fighting compartment 6 is activated to perform rapid fire extinguishing.

[0055] In some possible solutions, a fire escape is provided on the side of the main body 7 of the battery swapping station away from the battery swapping doorway 71 to avoid the fire transfer device and the thermal runaway battery box. The fire transfer device can drive the thermal runaway battery box out of the fire escape and into the fire compartment 6.

[0056] The main body 7 of the battery swapping station may include an upper cavity and a lower cavity. The lower cavity houses a transfer seat 2 and multiple battery holders 10. The battery holders 10 are used to place battery boxes, and the transfer seat 2 is used to temporarily store the battery boxes. The battery swapping robot 9 can be installed in the upper cavity, and the battery swapping doorway 71 connects to the upper cavity. The upper and lower cavities are interconnected. A fire hydrant outlet connects to the lower cavity, and a fire transfer device is installed in the lower cavity. The fire transfer device can directly drive the transfer seat 2 and the battery boxes located on the transfer seat 2 out of the lower cavity and ultimately into the fire compartment 6.

[0057] In some possible implementations, the fire-fighting compartment 6 has a fire-fighting chamber and an opening communicating with the fire-fighting chamber. The opening is located on the side of the fire-fighting compartment 6 and faces the battery swapping station body 7, or the opening is located on the top of the fire-fighting compartment 6. When the opening is located on the side of the fire-fighting compartment 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 compartment 6. When the opening is located on the top of the fire-fighting compartment 6, the structure of the fire-fighting transfer device is similar to that of a conventional battery swapping robot 9. It can grab the thermal runaway battery box with a lifting device, and then the telescopic arm assembly of the fire-fighting transfer device drives the lifting device and the thermal runaway battery box to extend out of the battery swapping station body 7 and move the lifting device to the top of the opening. Then, the lifting device is controlled to lower the battery box to place it into the fire-fighting compartment 6.

[0058] Specifically, the fire transfer device has a horizontal telescopic section and a vertical lifting section mounted on the horizontal telescopic section. The horizontal telescopic section can be the aforementioned telescopic arm. The vertical lifting section can grab or release thermally runaway battery boxes. The vertical lifting section includes a lifting device, which may specifically include a winch and a battery gripper. The winch is wound with a lifting rope, which is connected to the battery gripper. The horizontal telescopic section can drive the vertical lifting section to extend out of the cavity of the battery swapping station body 7. The vertical lifting section can drive the battery box down to the opening at the top of the fire compartment 6 and unload it into the fire compartment.

[0059] In some possible implementations, the battery swapping station includes a battery swapping robot 9 disposed within the cavity. The battery swapping robot 9 has a telescopic arm that can extend or retract within the cavity to perform battery swapping operations. In this implementation, the battery swapping station is also equipped with the battery swapping robot 9 and a fire-fighting transfer device. The fire-fighting transfer device is used only to transfer the thermal runaway battery box to the fire-fighting compartment 6 and is not used to perform battery swapping operations.

[0060] In some possible implementations, the battery swapping station includes a canopy 8, which is disposed on one side of the main body 7 of the battery swapping station along the width direction, forming a battery swapping channel between the canopy 8 and the main body 7 of the battery swapping station, and a fire compartment 6 is located on the side of the main body 7 of the battery swapping station away from the battery swapping channel.

[0061] Example 2

[0062] Embodiment 2 of this application provides a more detailed description of the battery swapping station, which includes: a battery swapping station body 7, a fire-fighting compartment 6, a fire-fighting transfer device, a transfer seat 2, and multiple battery holders 10. The battery swapping station body 7 has a cavity, and the transfer seat 2 and each of the battery holders 10 are disposed within the cavity. The transfer seat 2 and each of the battery holders 10 are arranged sequentially along the extension direction of the battery swapping station body 7. The fire-fighting compartment 6 is located outside the cavity, and the fire-fighting transfer device is at least partially disposed within the cavity. The fire-fighting transfer device and the transfer seat 2 are driven together, and the fire-fighting transfer device can drive the transfer seat 2 to slide away from the cavity and move into the fire-fighting compartment 6.

[0063] The transfer station 2 in this application serves two purposes: as a temporary battery support for transfer and as a support for fire trucks. The transfer station 2, located in the center of the battery swapping station, acts as a temporary fire standby area, eliminating the need for separate space within the main body 7 of the battery swapping station.

[0064] The battery swapping station main body 7 of this application is externally equipped with a fire-fighting compartment 6. The battery swapping station main body 7 and the fire-fighting compartment 6 are isolated from each other, forming an independent fire-fighting space, which will not affect other battery boxes inside the battery swapping station main body 7. The battery swapping station main body 7 is equipped with a fire-fighting transfer device, which can directly transfer the transfer seat 2 and the thermally runaway battery box on it to the fire-fighting compartment 6 for fire-fighting treatment, thereby improving fire-fighting efficiency, achieving rapid fire extinguishing effect, and improving the safety of the battery swapping station.

[0065] The main body 7 of the battery swapping station is equipped with a fire escape opening to allow the transfer station 2 and battery boxes to enter and exit the main body 7. The main body 7 may include an upper cavity and a lower cavity. The lower cavity houses the transfer station 2 and multiple battery holders 10. The battery holders 10 are used to place the battery boxes, and the transfer station 2 is used to temporarily store the battery boxes. The battery swapping robot 9 can be installed in the upper cavity, and the battery swapping doorway 71 connects to the upper cavity. The fire escape opening connects to the lower cavity, and a fire transfer device is installed in the lower cavity. The fire transfer device can directly drive the transfer station 2 and the battery boxes located on the transfer station 2 out of the lower cavity and finally into the fire compartment 6.

[0066] See some possible implementations. 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 a first position or a second position. When the transfer seat 2 is in the first position, the transfer seat 2 and each of the battery holders 10 are 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 vent, making it difficult for the battery box to be moved horizontally through the fire vent. To solve this technical problem, when the transfer seat 2 is in the second position, the position of the transfer seat 2 is lower than each of the battery holders 10. Specifically, when the transfer seat 2 is in the second position, the top of the battery box placed on the transfer seat 2 is lower than the upper edge of the fire vent. The horizontal transfer mechanism 3 can cooperate with the transfer seat 2 to drive the transfer seat 2 to slide away from the cavity and move into the fire compartment 6. It should be noted that the thermally runaway battery box can be picked up by the battery swapping robot 9 and placed on the transfer station 2.

[0067] See some possible implementations. Figures 5 to 10 As shown, the battery swapping station includes a fixed frame connected to the main body 7 of the battery swapping station. 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. The transfer seat 2 is supported on the lifting seat 12. The lifting assembly and the lifting seat 12 are connected by a transmission to drive the lifting seat 12 to slide along the longitudinal guide rail 11, thereby driving the transfer seat 2 to move up and down.

[0068] 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 pulley 122 is disposed on one side of the main board 121 along the thickness direction. Each pulley 122 is 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. The lifting assembly and the main board 121 are connected in a transmission manner.

[0069] See some possible implementations. 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 together. 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 main body 7 of the battery swapping station. Both ends of the telescopic component 15 are respectively hinged to the second connecting rod 14 and the main body 7 of the battery swapping station. The telescopic component 15 can extend and retract, which can 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.

[0070] The lifting mechanism 1 has two lifting components on each side of the transfer seat 2. The second connecting rods 14 of the two lifting components 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 together. The synchronous connecting rod 16, the first connecting rod 13, and the second connecting rod 14 can be connected by the same pin. The synchronous connecting rod 16, the two second connecting rods 14, and the main body 7 of the battery swapping station form a parallelogram mechanism. The bottom of the telescopic component 15 can be hinged to the bottom frame of the main body 7 of the battery swapping station. Regardless of the extent of the telescopic component 15's extension or retraction, the top synchronous connecting rod 16 always remains parallel to the bottom frame of the main body 7 of the battery swapping station. The synchronous connecting rod 16 enables the two lifting components to rise and fall synchronously. The lifting mechanism 1 provided in this embodiment effectively solves the problem of supporting the battery pack during placement and enabling rapid vertical descent, resulting in a stable and effective descent.

[0071] Furthermore, the lifting mechanism 1 also includes a stabilizing beam 17, which is connected to two lifting seats 12 located opposite each other on both sides of the transfer seat 2 along the width direction, i.e., the main board 121 of the lifting seats 12. This allows the lifting components on both sides of the transfer seat and each lifting seat 12 to lift and lower synchronously, thereby achieving a smooth lifting or lowering of the transfer seat 2 and the thermally runaway battery box on the transfer seat 2.

[0072] See some possible implementations. Figure 10As shown, the transfer seat 2 has a seat body 21 and a plurality of columns 22 disposed on the edge of the seat body 21. Each column 22 is provided with a support foot 23 at its end, and each support foot 23 is supported on a corresponding lifting seat 12.

[0073] See Figure 9 and Figure 10 As shown, the horizontal transfer mechanism 3 includes a push-pull trolley 31, a transmission assembly, and a drive component 36. The transmission assembly and the drive component 36 are both located in the main body 7 of the battery swapping station. The transfer seat 2 is located under the second work position. The transfer seat 2 and the push-pull trolley 31 are in a transmission cooperation. The drive component 36 and the transmission assembly are in a transmission cooperation. The transmission assembly and the push-pull trolley are in a transmission cooperation to drive the push-pull trolley 31 to push the transfer seat 2 out of the cavity and move into the fire compartment 6.

[0074] 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 process of the push-pull trolley 31 moving towards the fire chamber 6, one of the thrust plates 312 abuts against the transfer seat 2 and moves towards the fire chamber 6. During the process of the push-pull trolley 31 moving towards the main body of the battery swapping station 7, the other thrust plate 312 abuts against the transfer seat 2 and moves towards the cavity.

[0075] In some possible implementations, the battery swapping station includes a guide rail 4 extending from the cavity into the fire compartment 6, see [link to relevant documentation]. Figure 9 As shown, the push-pull trolley 31 has a guide rail mating beam 313, which is vertically connected to the main beam 311. The guide rail mating beam 313 has a first track mating wheel 314 at each end, and the first track mating wheel 314 is slidably connected to the corresponding guide rail 4.

[0076] In some possible implementations, the transfer seat 2 has a second track-fitting wheel 24, which is supported on the guide rail 4 when the transfer seat 2 is located in the second working position. Both the first track-fitting wheel 314 and the second track-fitting wheel 24 are rotatably supported on the guide rail 4, reducing the sliding resistance between the push-pull trolley 31 and the transfer seat 2.

[0077] In some possible implementations, the transmission assembly includes a rotating base 34 and a strip-shaped component. A rotating body 361 is mounted on the rotating base 34. A drive component 36 has the rotating body 361. The strip-shaped component is fitted onto the rotating body 361 on both the drive component 36 and the rotating base 34. Both ends of the strip-shaped component are connected to the push-pull trolley 31. The strip-shaped component can be a chain, belt, etc. The drive component 36 can include a gearbox and a motor or hydraulic motor that drives the gearbox input. The output end of the gearbox is connected to the rotating body 361.

[0078] See some possible implementations. Figure 4 As shown, the fire-fighting compartment 6 has a door 5, a door drive mechanism, and a compartment shell. The compartment shell has a fire-fighting chamber and a compartment opening communicating with the fire-fighting chamber. The compartment opening can be connected to a fire hydrant. The door 5 is slidably mounted on the compartment shell. The door drive mechanism is driven by the door 5 to drive the door 5 to close or open the compartment opening. A door 5 for isolation is provided between the battery swapping station body 7 and the fire-fighting compartment 6. After the thermal runaway battery is installed in the fire-fighting compartment 6, the door 5 can close quickly to ensure isolation from fire and smoke, preventing damage to other battery packs.

[0079] Example 3

[0080] Embodiment 3 of this application provides a fire-fighting method for a battery swapping station, including:

[0081] Step S1: The battery swapping station receives a fire alarm command;

[0082] The battery swapping station is equipped with temperature and smoke sensors, and the battery box is equipped with sensors. When some sensors detect an abnormality, they can trigger a fire command to be sent to the control terminal of the battery swapping station, causing the battery swapping station to start the fire extinguishing procedure.

[0083] Step S2: The battery swapping station controls the battery swapping robot 9 to transfer the thermally runaway battery box to the transfer station 2;

[0084] In this step, the battery swapping robot 9 walks to the thermal runaway battery box, grabs the thermal runaway battery box, and at the same time, the door 5 of the fire compartment 6 opens, and the battery swapping robot 9 places the thermal runaway battery box on the transfer seat 2.

[0085] Step S3: The battery swapping 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.

[0086] Optionally, in step S2, the transfer station 2 is located at the first work station;

[0087] Step S3 includes:

[0088] Step S31: The lifting mechanism 1 of the fire transfer device drives the transfer seat 2 to descend to the second working position;

[0089] In this step, when the transfer seat 2 senses that the thermal runaway battery pack has fallen into place, it immediately starts the lifting mechanism 1 to lower the transfer seat 2 and the thermal runaway battery box from the high position to the guide rail 4 at the bottom.

[0090] When the battery swapping robot 9 lifts the thermally runaway battery box onto the transfer seat 2, the telescopic component 15 (lifting cylinder) retracts, and the support plate 1211 on the lifting seat 12 supports the support legs 23 of the transfer seat 2, which then descends until the second track-fitting wheel 24 on the transfer seat 2 lands on the guide rail 4. At this point, the transfer seat 2 disengages from the lifting mechanism 1, and the sensor 18 located on the longitudinal guide rail 11 senses the corresponding information, triggering the retraction of the telescopic component 15 to stop.

[0091] Step S32: The horizontal transfer mechanism 3 of the fire transfer device drives the transfer seat 2 to slide away from the cavity and move into the fire compartment 6.

[0092] In this step, as the transfer seat 2 descends onto the guide rail 4, the horizontal transfer mechanism 3 is activated. The traction chain (a specific form of the strip body 35) drives the push-pull trolley 31, which hooks onto the transfer seat 2 and moves along the guide rail 4 to move the thermally runaway battery pack from the main body 7 of the battery swapping station to the fire compartment 6.
