[0069] Example 1

[0070] like Figures 1 to 9As shown, an embodiment of the present application provides a battery swap station, comprising: a box body 1, a robot track 2, a fire compartment 3 and a battery swap robot 4. The box body 1 has a cavity and a through hole 13 connected to the space. The cavity is used to accommodate a battery box 10. The robot track 2 is arranged through the through hole 13. The robot track 2 is partially located in the cavity and partially located outside the box body 1. The fire compartment 3 is located outside the box body 1. The battery swap robot 4 can be movably arranged on the robot track. When the door body 6 opens the through hole 13, the battery swap robot 4 can drive the battery box 10 with thermal runaway to move to the outside of the box body 1 to transfer the battery box 10 with thermal runaway to the fire compartment 3.

[0071] The battery swap station of the present application can, when a thermal runaway fault occurs in the battery box 10, the battery swap robot 4 can grab the thermal runaway battery box 10 and move it to the outside of the box body 1, and transfer the battery box 10 to the fire fighting cabin 3 for fire fighting treatment, thereby improving the fire fighting treatment efficiency, achieving the effect of rapid fire extinguishing, improving the safety of the battery swap station, avoiding the thermal runaway battery box 10 from causing damage to the box body 1, the battery swap robot 4 and the normal battery box 10, and reducing losses.

[0072] In some possible embodiments, such as Figure 1 and Figure 2 As shown, the battery swap station includes a door body 6 and a door drive mechanism 7. The door body 6 is movably arranged on the box body 1, and the door drive mechanism 7 is arranged on the box body 1. The door drive mechanism 7 and the door body 6 are connected in a transmission manner to drive the door body 6 to open or close the opening. When the thermal runaway battery box 10 needs to be moved out of the box body 1, the door drive mechanism 7 drives the door body 6 to rotate and open the passage 13, as shown in FIG. Figure 4 and Figure 5 As shown, the battery-changing robot 4 located in the box 1 can grab the battery box 10 and move it out of the box 1 along the robot track 2, and transfer the thermal runaway battery box 10 to the fire compartment 3. Under normal conditions, that is, when there is no thermal runaway battery box 10 in the box 1, the door 6 is in a closed state, keeping the through opening 13 closed. Figure 1 shown.

[0073] In some possible embodiments, such as Figure 1 As shown, the door body 6 is hinged to the box body 1, and the door driving mechanism 7 includes a winding device 71 and a pull rope 72. The winding device 71 is installed on the box body 1, one end of the pull rope 72 is wound on the winding device 71, and the other end of the pull rope 72 is connected to the door body 6. The winding device 71 winds up the pull rope 72, which can pull the door body 6 to rotate and open the passage 13. The winding device 71 releases the pull rope 72, and the door body 6 can rotate to close the passage 13.

[0074] The winding device 71 can be a winch. The pull rope 72 can be a steel wire rope. The door body 6 can be hinged at the top wall of the box body 1. The bottom of the door body 6 is a free end. The winding device 71 winds the pull rope 72 to pull the free end of the door body 6 upward to rotate the door body 6 so that the door body 6 is approximately horizontal, thereby opening the passage 13. Figure 4 and Figure 5 After the thermal runaway battery box 10 is transferred, the battery swap robot 4 returns to the box body 1. The winding device 71 releases the pull rope 72, and the door body 6 gradually rotates downward under the action of gravity, gradually closing the passage 13.

[0075] In some possible embodiments, such as Figure 3 As shown, the door body 6 includes a door panel 61, a block 62 and a traction matching portion 63. The top end of the door panel 61 is hinged to the container, the block 62 is connected to the door panel 61, the traction matching portion 63 is rotatably arranged on the door panel 61, and the pull rope 72 is connected to the traction matching portion 63. The winding device 71 winds up the pull rope 72 and can pull the traction matching portion 63 to rotate until it stops at the block 62. The winding device 71 continues to wind up the pull rope 72 and can pull the door body 6 to rotate and open the passage 13.

[0076] The stopper 62 extends along the thickness direction of the door panel 61. The traction fitting portion 63 is located on the side of the stopper 62 away from the rotation axis of the door body 6. Figure 1 As shown, the traction fitting portion 63 is generally vertically downward, close to or in proximity to the door panel 61. The traction fitting portion 63 does not significantly protrude from the door panel 61 and is unlikely to interfere with external structures. When the door body 6 needs to be opened, the winding device 71 winds the pull rope 72 in two states. In the first state, the pull rope 72 gradually pulls the traction fitting portion 63, causing the traction fitting portion 63 to rotate toward the side of the stop block 62 and eventually stop at the stop block 62. Figure 3 As shown, at this time, the pulling and fitting portion 63 extends substantially in a direction perpendicular to the door panel 61. During this process, the door panel 61 does not move and remains closed through the opening 13. In the second state, as the winding device 71 continues to wind the pull rope 72, the pull rope 72 can pull the door body 6 to rotate as a whole, gradually opening the opening 13. Figure 4 and Figure 5 shown.

[0077] In some possible embodiments, combined Figure 3 and Figure 8As shown, the traction matching portion 63 includes a rotating shaft 631, a first extension 632, and a second extension 633. The rotating shaft 631 is rotatably connected to the door panel 61. For example, a plurality of rings can be provided on the door panel 61, each ring being located on the same axis, and the rotating shaft 631 can be provided through each ring. One end of the first extension 632 is connected to the rotating shaft 631, and the second extension 633 is connected to the end of the first extension 632 away from the rotating shaft 631. The second extension 633 and the first extension 632 have an included angle. Figure 3 As shown, when the traction-coupling portion 63 is rotated to abut against the stopper 62, the first extension 632 extends along the thickness direction of the door panel 61, and the second extension 633 extends substantially parallel to the door panel 61. The pull cord 72 is connected to one end of the second extension 633 facing away from the first extension 632. The structural design of the first and second extensions 632 and 633 makes it easier for the pull cord 72 to pull the door 6 to rotate and open the passage 13 when the traction-coupling portion 63 is rotated to abut against the stopper 62.

[0078] In some possible embodiments, such as Figure 5 、 Figure 7 and Figure 8 As shown, the housing 1 is provided with a locking seat 14, and a locking head 634 is provided at the end of the rotating shaft 631. When the door 6 is closed through the opening 13 and the traction-coupling portion 63 is rotated to a limit angle away from the stop 62 (e.g., when the first extension 632 is parallel to or in contact with the door panel 61), the locking head 634 and the locking seat 14 lock and cooperate. The door 6 cannot be opened by external forces, thus preventing the door 6 from opening accidentally. When the door 6 is closed through the opening 13 and the traction-coupling portion 63 is rotated until it abuts the stop 62, the locking head 634 disengages from the locking seat 14.

[0079] In the normal state, the door body 6 is closed through the opening 13, the pull-fitting portion 63 rotates to its limit position away from the stop 62, and the first extension 632 is vertically downward. The lock head 634 and the locking seat 14 lock and engage. When the door body 6 needs to be opened, the winding device 71 winds the pull rope 72, which pulls the pull-fitting portion 63 to rotate. When the pull-fitting portion 63 rotates and stops against the stop 62, the lock head 634 and the locking seat 14 separate, and the locking mechanism is released. The winding of the winding device 71 automatically releases the lock head 634 and the locking seat 14, simplifying the door opening process. In the process of the winding device 71 releasing the pull rope 72 to close the door body 6 through the opening 13, when the winding device 71 releases the pull rope 72 to a sufficient length, the door panel 61 closes the opening 13, but the rotating shaft 631 may not rotate to the state where the lock head 634 and the locking seat 14 are locked. At this time, an external force can be applied to the traction matching part 63 to make the traction matching part 63 rotate downward to the extreme position. At this time, the lock head 634 and the locking seat 14 are locked and matched.

[0080] Specifically, such as Figure 7 As shown, the locking seat 14 has a base 141, a first locking portion 142 and a second locking portion 143. The base 141 is connected to the box body 1. The first locking portion 142 and the second locking portion 143 are both arranged on the base 141. The first locking portion 142 and the second locking portion 143 are arranged in sequence along the height direction of the box body 1. The first locking portion 142 includes a limiting portion 1421 and an extending portion 1422 connecting the limiting portion 1421 and the base 141. Figure 8 As shown, the lock head 634 has two side structures, each with two latching protrusions 6341. When the door body 6 is closed through the opening 13 and the traction-coupling portion 63 is rotated to the extreme angle away from the stopper 62, one side structure is located between the base 141 and the limiting portion 1421, with its two latching protrusions 6341 located on either side of the extension 1422. The other side structure has two latching protrusions 6341 located on either side of the second locking portion 143. This state indicates that the lock head 634 is locked with the locking seat 14. When the door body 6 is closed through the opening 13 and the traction-coupling portion 63 is rotated until it abuts the stopper 62, one side structure disengages from the first locking portion 142, and the other side structure disengages from the second locking portion 143. This state indicates that the lock head 634 is unlocked with the locking seat 14.

[0081] In some possible embodiments, such as Figure 2As shown, the battery swap station includes a mounting plate and a fixed pulley 9. The mounting plate is located on the top wall of the box body 1, near the passage 13. Both the winding device 71 and the fixed pulley 9 are located on the mounting plate. The fixed pulley 9 is located on the side of the winding device 71 near the passage 13. The pull rope 72 on the winding device 71 is diverted by the fixed pulley 9 and then connected to the door body 6. The provision of the fixed pulley 9 allows the pull rope 72 to extend smoothly downward to connect to the door panel 61. The provision of the pulley helps reduce winding resistance.

[0082] The fixed pulley 9 may include a bracket and a wheel body. The bracket may be fixed to the mounting plate, and the bracket may extend toward the outside of the box body 1, so that after the wheel body is connected to the bracket, the wheel body at least partially protrudes from the end of the box body 1, so that the pull rope 72 passing through the wheel body will not touch the surface of the box body 1 after extending downward.

[0083] In some possible embodiments, such as Figure 8 As shown, the lower edge of the door body 6 is provided with an escape opening. When the door body 6 closes the passage opening 13, the robot track 2 passes through the escape opening. By providing the escape opening on the door body 6, when the door body 6 is closed, there will be no interference with the robot track 2, and the door body 6 can smoothly close the passage opening 13.

[0084] In some possible implementations, the battery swap station includes a flexible closing piece 64, which is connected to the door body 6 and covers the avoidance opening. A track opening is provided on the flexible closing piece 64, and the cross-sectional shape of the track opening matches that of the track. When the door body 6 is closed through the opening 13, the track passes through the track opening on the flexible closing piece 64.

[0085] When the door 6 approaches the closed passage 13, the robot track presses against the flexible sheet, causing it to deform. The flexible sheet then separates at the escape opening. The structures of the flexible sheet on both sides of the escape opening separate and are positioned on both sides of the robot track 2, eventually allowing the track to pass through the track opening on the flexible sealing sheet 64. The design of the flexible sealing sheet 64 improves the sealing performance of the structure between the door 6 and the box 1, preventing animals from entering the box 1.

[0086] In some possible implementations, the battery swap station includes an external bracket 5, and the robot track 2 includes an inner track 21 and an outer track 22. The inner track 21 is disposed within the housing 1 and located within the cavity, and the outer track 22 is disposed on the external bracket 5. When the external bracket 5 is connected to the housing 1, the outer track and the inner track are spliced to form a complete robot track 2. The outer track and the inner track do not need to be directly connected; they only need to be on the same straight line. The battery swap robot 4 can pass smoothly between the outer track and the inner track.

[0087] In some possible embodiments, such as Figure 2 and Figure 5 As shown, the external bracket 5 includes a horizontal frame 51 and a support leg 52. The horizontal frame 51 is connected to the box body 1 through fasteners, the outer track is connected to the horizontal frame 51, and the support leg 52 is vertically connected to the horizontal frame 51. The support leg 52 is supported on a supporting surface.

[0088] Example 2

[0089] The embodiment of the present application further describes the battery swap station in detail, and the battery swap station includes: a box body 1, a robot track 2, a fire compartment 3 and a battery swap robot 4. The box body 1 has a cavity and a passage 13 connected to the space, and the cavity is used to accommodate the battery box 10. The robot track 2 is arranged through the passage 13, and the robot track 2 is partially located in the cavity and partially located outside the box body 1. The fire compartment 3 is located outside the box body 1. The battery swap robot 4 can be movably arranged on the robot track. When the door body 6 opens the passage 13, the battery swap robot 4 can drive the battery box 10 with thermal runaway to move to the outside of the box body 1, so as to transfer the battery box 10 with thermal runaway to the fire compartment 3.

[0090] The battery swap station of the present application can, when a thermal runaway fault occurs in the battery box 10, the battery swap robot 4 can grab the thermal runaway battery box 10 and move it to the outside of the box body 1, and transfer the battery box 10 to the fire fighting cabin 3 for fire fighting treatment, thereby improving the fire fighting treatment efficiency, achieving the effect of rapid fire extinguishing, improving the safety of the battery swap station, avoiding the thermal runaway battery box 10 from causing damage to the box body 1, the battery swap robot 4 and the normal battery box 10, and reducing losses.

[0091] In some possible embodiments, such as Figure 2 As shown, the robot track 2 includes an inner track 21 and an outer track 22, the inner track 21 is arranged in the box body 1 and is located in the cavity, the outer track 22 is at least partially located outside the box body 1, the outer track 22 and the inner track 21 are docked, and the fire compartment 3 is located at the bottom of the outer track 22. The outer track and the inner track do not need to be directly connected, and the two can be located in the same straight line. The battery-swapping robot 4 can pass smoothly between the outer track and the inner track. After the battery-swapping robot 4 moves from the inner track to the outer track, it can directly drop the faulty battery box 10 into the fire compartment 3 below.

[0092] In some possible implementations, the inner rail 21 and the outer rail 22 extend along the same straight line. The fire fighting chamber 3 is located at one end of the box body 1 along the length direction. The outer rail 22 is located above the fire fighting chamber 3.

[0093] In some possible implementations, the battery swap station includes an external bracket 5, on which an outer rail 22 is mounted. The external bracket 5 is detachably connected to the housing 1. When the external bracket 5 is connected to the housing 1, the inner rail 21 and the outer rail 22 are docked. The detachable connection between the external bracket 5 and the housing 1 allows for easy disassembly and installation, facilitating assembly and transportation of the battery swap station.

[0094] In some possible embodiments, the external support 5 includes a horizontal frame 51 and legs 52. The horizontal frame 51 is detachably connected to the housing 1 via fasteners. The outer rail 22 is connected to the horizontal frame 51. The legs 52 are perpendicularly connected to the horizontal frame 51 and supported on a support surface. One end of the horizontal frame 51 is fixed to the housing 1, and the other end is stably supported by the legs 52.

[0095] In some possible implementation schemes, a storage space is formed between the box body 1, the supporting legs 52 and the horizontal frame 51, and the fire fighting chamber 3 is arranged in the storage space, thereby fully utilizing the space.

[0096] In some possible embodiments, such as Figure 6 As shown, a stop block 221 is provided at one end of the outer track 22 facing away from the inner track 21. An elastic member 41 is provided on the side of the battery-swapping robot 4 close to the stop block 221. When the battery-swapping robot 4 reaches the end of the outer track 22, the elastic member 41 abuts against the stop block 221. The stop block 221 serves as a limiter. By providing the elastic member 41 on the battery-swapping robot 4, a buffering effect is provided to prevent the battery-swapping robot 4 from rigidly colliding with the stop block 221.

[0097] In some possible implementation schemes, the battery swap station may include a travel assist frame 222, and the travel assist frame 222 is arranged on the outer track 22.
