Description

Technical Field

[0001] This utility model relates to the field of battery swapping technology, and more specifically, to a battery swapping station capable of emergency fire-fighting treatment of problematic battery packs. 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.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0020] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Example 1 like Figures 1 to 9As shown in the illustration, this application provides a detailed description of a battery swapping station, which includes: a housing 1, a robot track 2, a fire-fighting compartment 3, a door 6, and a battery swapping robot 4. The housing 1 has a cavity and a passageway 13 connecting to the cavity, the cavity being used to accommodate a battery box 10. The door 6 is movably connected to the housing 1 and is used to close or open the passageway 13. The robot track 2 is disposed through the passageway 13, with part of the robot track located inside the cavity and part located outside the housing 1. The fire-fighting compartment 3 is located outside the housing 1. The battery swapping robot 4 is movably disposed on the robot track. When the door 6 is open and the passageway 13 is open, the battery swapping robot 4 can move the thermally runaway battery box 10 to the outside of the housing 1, thereby transferring the thermally runaway battery box 10 into the fire-fighting compartment 3.

[0023] When a thermal runaway fault occurs in the battery box 10, the battery swapping robot 4 can grab the thermally runaway battery box 10, move it to the outside of the box 1, and transfer the battery box 10 to the fire chamber 3 for fire fighting. This improves the efficiency of fire fighting, achieves rapid fire extinguishing, enhances the safety of the battery swapping station, and prevents the thermally runaway battery box 10 from damaging the box 1, the battery swapping robot 4, and the normal battery box 10, thus reducing losses.

[0024] In some possible implementations, 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 disposed within the housing 1 and located inside the cavity. The outer track 22 is at least partially located outside the housing 1 and is connected to the inner track 21. 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; they only need to be on the same straight line. The battery swapping robot 4 can smoothly pass between the outer track and the inner track. After moving from the inner track to the outer track, the battery swapping robot 4 can directly place the faulty battery box 10 into the fire compartment 3 below.

[0025] In some possible implementations, the inner rail 21 and the outer rail 22 extend along the same straight line. The fire compartment 3 is located at one end of the housing 1 along its length. The outer rail 22 is located above the fire compartment 3.

[0026] In some possible implementations, the battery swapping station includes an external support frame 5, on which an external rail 22 is mounted. The external support frame 5 is detachably connected to the housing 1. With the external support frame 5 connected to the housing 1, the inner rail 21 and the outer rail 22 are aligned. The detachable connection between the external support frame 5 and the housing 1 allows for easy disassembly and installation, facilitating the assembly and transportation of the battery swapping station.

[0027] In some possible implementations, the external support 5 includes a horizontal frame 51 and legs 52. The horizontal frame 51 is detachably connected to the housing 1 by fasteners. An external rail 22 is connected to the horizontal frame 51. The legs 52 are vertically connected to the horizontal frame 51 and support a support surface. One end of the horizontal frame 51 is fixed to the housing 1, while the other end is stably supported by the legs 52.

[0028] In some possible implementations, the housing 1, the support legs 52 and the horizontal frame 51 form a receiving space, and the fire compartment 3 is set in the receiving space, thereby making full use of the space.

[0029] In some possible implementations, such as Figure 6 As shown, a stop block 221 is provided at the end of the outer track 22 opposite to the inner track 21. An elastic element 41 is provided on the side of the battery swapping robot 4 near the stop block 221. When the battery swapping robot 4 moves to the end of the outer track 22, the elastic element 41 abuts against the stop block 221. The stop block 221 serves as a limiting element. By providing the elastic element 41 on the battery swapping robot 4, a buffering effect is achieved, preventing rigid collisions between the battery swapping robot 4 and the stop block 221.

[0030] In some possible implementations, the battery swapping station may include a travel assist frame 222, which is disposed on the outer track 22. A first sensor and a second sensor are disposed on the battery swapping robot 4, arranged sequentially along the length of the outer track 22. The battery swapping robot 4 has a walking mechanism. During the movement of the battery swapping robot 4 towards the end of the outer track 22, the first sensor generates a control signal triggering the walking mechanism to slow down when it passes the travel assist frame 222, and the second sensor generates a signal triggering the walking mechanism to stop when it passes the travel assist frame 222, thus facilitating the slowing down and stopping of the battery swapping robot 4. It should be noted that the first and second sensors can be contact switches or infrared sensors. During the movement of the battery swapping robot 4, when the travel assist frame 222 approaches a contact switch or infrared sensor, the corresponding signal is triggered.

[0031] In some possible implementations, such as Figure 9 As shown, the fire-fighting chamber 3 includes a shell 31, an overflow pipe 32, an inlet pipe 33, and a drain pipe 34. The shell 31 has a water-holding cavity and a top opening connecting to the water-holding cavity. The overflow pipe 32, the inlet pipe 33, and the drain pipe 34 are all connected to the shell 31 and communicate with the water-holding cavity. By providing a top opening at the top of the fire-fighting chamber 3, the battery-swapping robot 4 can easily transfer the faulty battery box 10 directly downwards into the water-holding cavity, causing the liquid in the water-holding cavity to submerge the battery box 10, thereby achieving the effect of extinguishing the fire.

[0032] In some possible implementations, the fire-fighting compartment 3 includes a reinforcing frame 35, which is fitted onto the outer wall of the compartment shell 31 and connected to the compartment shell 31. The reinforcing frame 35 may include multiple intersecting beams, and the reinforcing frame 35 may be welded and fixed to the compartment shell 31, thereby enhancing the structural strength of the fire-fighting compartment 3.

[0033] In some possible implementations, such as Figure 1 As shown, the cavity inside the housing 1 includes a bottom cavity 11 and a top cavity 12. A battery base is disposed in the bottom cavity 11, and the battery base is used to load the battery box 10. The top cavity 12 is connected to the bottom cavity 11. The portion of the robot track 2 located inside the housing 1 is disposed on the side of the top cavity 12 near the bottom cavity 11.

[0034] The housing 1 may include an upper housing and a lower housing, with the upper housing located on top of the lower housing. The upper housing has a top cavity 12, and the lower housing has a bottom cavity 11. The upper and lower housings are detachably connected, facilitating transportation and assembly. The robot track 2 includes two rails located on both sides of the upper housing along its width. The aforementioned passage opening 13 is provided at one end of the upper housing along its length, and a door 6 is hinged to the upper housing for closing or opening the passage opening 13.

[0035] Example 2 like Figures 1 to 9 As shown in the illustration, this application embodiment continues to describe the battery swapping station, which includes: a housing 1, a robot track 2, a fire-fighting compartment 3, and a battery swapping robot 4. The housing 1 has a cavity and a passage 13 connecting the cavity. The cavity is used to accommodate the battery box 10. The robot track 2 is disposed through the passage 13. The robot track 2 is partially located inside the cavity and partially located outside the housing 1. The fire-fighting compartment 3 is located outside the housing 1. The battery swapping robot 4 is movably disposed on the robot track. When the door 6 opens the passage 13, the battery swapping robot 4 can move the thermally runaway battery box 10 to the outside of the housing 1, so as to transfer the thermally runaway battery box 10 into the fire-fighting compartment 3.

[0036] When a thermal runaway fault occurs in the battery box 10, the battery swapping robot 4 can grab the thermally runaway battery box 10, move it to the outside of the box 1, and transfer the battery box 10 to the fire chamber 3 for fire fighting. This improves the efficiency of fire fighting, achieves rapid fire extinguishing, enhances the safety of the battery swapping station, and prevents the thermally runaway battery box 10 from damaging the box 1, the battery swapping robot 4, and the normal battery box 10, thus reducing losses.

[0037] In some possible implementations, such as Figure 1 and Figure 2As shown, the battery swapping station includes a door body 6 and a door drive mechanism 7. The door body 6 is movably mounted on the housing 1, and the door drive mechanism 7 is mounted on the housing 1. The door drive mechanism 7 and the door body 6 are connected by a drive mechanism to drive the door body 6 to open or close the opening. When it is necessary to remove the thermal runaway battery box 10 from the housing 1, the door drive mechanism 7 drives the door body 6 to rotate and open the access port 13, such as... Figure 4 and Figure 5 As shown, the battery swapping robot 4, located inside the housing 1, can grab the battery box 10 and move it out of the housing 1 along the robot track 2, transferring the thermal runaway battery box 10 to the fire compartment 3. Under normal conditions, i.e., when there is no thermal runaway battery box 10 inside the housing 1, the door 6 is closed, keeping the passageway 13 sealed. Figure 1 As shown.

[0038] In some possible implementations, such as Figure 1 As shown, the door 6 is hinged to the housing 1. The door drive mechanism 7 includes a winding device 71 and a pull rope 72. The winding device 71 is installed on the housing 1. One end of the pull rope 72 is wound around the winding device 71, and the other end of the pull rope 72 is connected to the door 6. The winding device 71 winds the pull rope 72, which can pull the door 6 to rotate and open the passage 13. When the winding device 71 releases the pull rope 72, the door 6 can rotate to close the passage 13.

[0039] The winding device 71 can be a winch. The pull rope 72 can be a steel wire rope. The door 6 can be hinged at the top to the top wall of the housing 1. The bottom of the door 6 is a free end. The winding device 71 winds the pull rope 72 to pull the free end of the door 6 upward, making the door 6 approximately horizontal, thereby opening the passageway 13, such as... Figure 4 and Figure 5 As shown. After the thermal runaway battery box 10 is transferred, the battery swapping robot 4 returns to the box 1. The winding device 71 releases the pull rope 72, and the door 6 gradually rotates downward under the action of gravity, gradually closing the passage 13.

[0040] In some possible implementations, such as Figure 3 As shown, the door body 6 includes a door panel 61, a stop block 62, and a traction engagement part 63. The top of the door panel 61 is hinged to the container. The stop block 62 is connected to the door panel 61. The traction engagement part 63 is rotatably disposed on the door panel 61. A pull rope 72 is connected to the traction engagement part 63. The winding device 71 winds the pull rope 72, which can pull the traction engagement part 63 to rotate until it stops against the stop block 62. The winding device 71 continues to wind the pull rope 72, which can pull the door body 6 to rotate and open the passage 13.

[0041] The stop block 62 extends along the thickness direction of the door panel 61. The traction engagement part 63 is located on the side of the stop block 62 opposite to the rotation axis of the door body 6. Under normal conditions, such as Figure 1 As shown, the traction engagement part 63 is generally vertically downward, fitting against or close to the door panel 61. The traction engagement part 63 does not protrude significantly from the door panel 61, making it less likely to interfere with external structures. When the door 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 engagement part 63, causing the traction engagement part 63 to rotate towards the stop block 62 and eventually stop against the stop block 62. Figure 3 As shown, at this time, the traction engagement part 63 extends approximately in the direction perpendicular to the door panel 61. During this process, the door panel 61 does not move, maintaining a closed passage 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 entire door body 6 to rotate, gradually opening the passage opening 13, as shown. Figure 4 and Figure 5 As shown.

[0042] In some possible implementation schemes, combined Figure 3 and Figure 8 As shown, the traction engagement part 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, multiple collars can be provided on the door panel 61, with each collar located on the same axis, and the rotating shaft 631 can pass through each collar. 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 that is 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 engagement part 63 is rotated to abut against the stop block 62, the first extension body 632 extends along the thickness direction of the door panel 61, and the extension direction of the second extension body 633 is approximately parallel to the door panel 61. The pull rope 72 is connected to the end of the second extension body 633 that is away from the first extension body 632. Through the structural design of the first extension body 632 and the second extension body 633, the pull rope 72 can more easily pull the door 6 to rotate and open the passage 13 when the traction engagement part 63 is rotated to abut against the stop block 62.

[0043] In some possible implementations, such as Figure 5 , Figure 7 and Figure 8As shown, a locking seat 14 is provided on the housing 1, and a lock 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 engagement part 63 is rotated to its limit angle away from the stop block 62 (such as when the first extension 632 is parallel to or in contact with the door panel 61), the lock head 634 and the locking seat 14 are locked together. The door 6 cannot be opened by external force, thus preventing accidental opening of the door 6. When the door 6 is closed through the opening 13 and the traction engagement part 63 is rotated to abut against the stop block 62, the lock head 634 disengages from the locking seat 14.

[0044] Under normal conditions, the door 6 is closed through opening 13, and the traction engagement part 63 rotates away from the stop block 62 to its limit position, with the first extension 632 pointing vertically downwards. The lock head 634 and the locking seat 14 are locked together. When it is necessary to open the door 6, the winding device 71 winds the pull rope 72, which pulls the traction engagement part 63 to rotate. When the traction engagement part 63 rotates to a stop against the stop block 62, the lock head 634 and the locking seat 14 separate, and the locking structure is released. That is, the locking structure of the lock head 634 and the locking seat 14 can be automatically released by the winding of the winding device 71, simplifying the door opening process. During the process of the winding device 71 releasing the pull rope 72 to close the door 6 through the passage 13, when the winding device 71 releases the pull rope 72 to a sufficient length, the door panel 61 closes the passage 13. However, the rotating shaft 631 may not have rotated 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 engagement part 63 to make the traction engagement part 63 rotate downward to the limit position. At this time, the lock head 634 and the locking seat 14 are locked together.

[0045] Specifically, such as Figure 7 As shown, the locking seat 14 has a base 141, a first locking part 142, and a second locking part 143. The base 141 is connected to the housing 1. The first locking part 142 and the second locking part 143 are both disposed on the base 141, and the first locking part 142 and the second locking part 143 are arranged sequentially at intervals along the height direction of the housing 1. The first locking part 142 includes a limiting part 1421 and an extension part 1422 connecting the limiting part 1421 and the base 141. Figure 8As shown, the lock head 634 has two side structures, each with two latching protrusions 6341. When the door 6 is closed through the opening 13 and the traction engagement part 63 is rotated to its limit angle away from the stop block 62, one side structure is located between the base 141 and the limiting part 1421, with its two latching protrusions 6341 located on both sides of the extension part 1422. The other side structure has two latching protrusions 6341 located on both sides of the second locking part 143. This state is the locked state between the lock head 634 and the locking seat 14. When the door 6 is closed through the opening 13 and the traction engagement part 63 is rotated to abut against the stop block 62, one side structure disengages from the first locking part 142, and the other side structure disengages from the second locking part 143. This state is the unlocked state between the lock head 634 and the locking seat 14.

[0046] In some possible implementations, such as Figure 2 As shown, the battery swapping station includes a mounting plate and a fixed pulley 9. The mounting plate is located on the top wall of the housing 1 near the access port 13. Both the winding device 71 and the fixed pulley 9 are mounted on the mounting plate. The fixed pulley 9 is located on the side of the winding device 71 near the access port 13. The pull rope 72 on the winding device 71 is deflected by the fixed pulley 9 and connected to the door 6. The fixed pulley 9 allows the pull rope 72 to extend smoothly downwards to connect to the door panel 61. The pulley also helps reduce winding resistance.

[0047] The fixed pulley 9 may include a bracket and a wheel body. The bracket may be fixed to the mounting plate and extend outward from the housing 1, such that after the wheel body is connected to the bracket, the wheel body protrudes at least partially from the end of the housing 1, so that the pull rope 72 wrapped around the wheel body will not contact the surface of the housing 1 after extending downward.

[0048] In some possible implementations, such as Figure 8 As shown, a clearance opening is provided at the lower edge of the door body 6. When the door body 6 is closed and the passage opening 13 is closed, the robot track 2 passes through the clearance opening. By providing a clearance opening on the door body 6, the door body 6 will not interfere with the robot track 2 when closed, and the door body 6 can smoothly close the passage opening 13.

[0049] In some possible implementations, the battery swapping station includes a flexible enclosure 64 connected to the door 6 and covering the clearance opening. The flexible enclosure 64 has a track opening with a cross-sectional shape that matches the track. When the door 6 is closed through the passage opening 13, the track passes through the track opening on the flexible enclosure 64.

[0050] As the door 6 approaches the closed passage 13, the robot track abuts against the flexible sheet, causing it to deform. The flexible sheet separates at the clearance opening, and the structures on both sides of the clearance opening separate and are located on either side of the robot track 2, ultimately 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 door 6 and the box 1, preventing animals from entering the box 1.

[0051] In some possible implementations, the battery swapping station includes an external support 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 in the cavity, while the outer track 22 is disposed on the external support 5. With the external support 5 connected to the housing 1, the outer track and the inner track are joined 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 swapping robot 4 can smoothly pass between the outer track and the inner track.

[0052] In some possible implementations, such as Figure 2 and Figure 5 As shown, the external support 5 includes a horizontal frame 51 and a support leg 52. The horizontal frame 51 is connected to the housing 1 by fasteners, the external rail is connected to the horizontal frame 51, and the support leg 52 is vertically connected to the horizontal frame 51 and is supported on the support surface.

[0053] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way.
