[0001] Cross-reference to Related Applications

[0002] The present disclosure is based on and claims priority to Chinese Patent Application No. 202421962281.4, filed on August 14, 2024, entitled “Battery transport assembly and battery swap station”, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD

[0003] Embodiments of the present disclosure relate to the technical field of battery, and in particular, to a battery transport assembly and a battery swap station. BACKGROUND

[0004] Places such as battery swap stations that store a large number of battery devices need to be equipped with fire-fighting mechanisms to handle them in time when the battery devices are in thermal runaway, and to avoid the spread of a single battery device thermal runaway to the remaining battery devices as much as possible.

[0005] Battery devices usually include a plurality of battery cells. With the advancement of technology, thermal runaway of one of the battery cells in the battery device may not spread to other battery cells in the battery device. However, the fire-fighting mechanism provided in the related art will sink the battery device in thermal runaway into a water tank, which will result in the entire battery device being scrapped, possibly leading to an enlarged loss.

[0006] SUMMARY

[0007] Therefore, embodiments of the present disclosure aim to provide a battery transport assembly and a battery swap station that can handle battery devices in thermal runaway in a way that causes less loss.

[0008] A first aspect of embodiments of the present disclosure provides a battery transport assembly, comprising: a transport platform, comprising a base and at least one guide rail arranged on the base, the guide rail having opposite first and second ends in a first direction, and the guide rail being downwardly inclined from the first end to the second end; a transport carrier for carrying a battery device, the transport carrier being in sliding fit with the guide rail; and at least one locking member for locking or unlocking the transport carrier and the transport platform.

[0009] The battery transport assembly of the present embodiment uses a transport method to handle battery devices in fire-fighting, so that the structure of the battery device can be damaged as little as possible while achieving the purpose of fire-fighting, thereby reducing the loss.

[0010] Further, the transfer assembly of the embodiment of the present disclosure is provided with a downwardly inclined guide rail and a transfer carrier in sliding cooperation with the guide rail. In this way, after the locking member unlocks the transfer carrier from the transfer platform, the transfer carrier will be able to slide along the guide rail under the action of gravity to realize the transfer of the battery device, and such a transfer mode has simple structure and high reliability.

[0011] In some embodiments, the locking member comprises a fixed part and a movable part, the fixed part is arranged on one of the transfer platform and the transfer carrier, and the movable part is movably connected with the fixed part to switch between the locked position and the unlocked position by moving relative to the fixed part. In the locked position, the movable part is connected to the other one of the transfer platform and the transfer carrier, and in the unlocked position, the movable part is disconnected from the other one of the transfer platform and the transfer carrier.

[0012] In the embodiment, the locking and unlocking of the transfer carrier and the transfer platform are realized by cooperation of the fixed part and the movable part. In this way, the structure of the locking member can be simplified, and the operation difficulty of the locking member in locking and unlocking can be reduced, so as to facilitate quick unlocking of the transfer carrier from the transfer platform when the thermal runaway problem occurs, and improve the reliability of the transfer assembly.

[0013] In some embodiments, the movable part comprises a movable block and a latch connected to the movable block, the fixed part has a through hole, the latch is inserted into the through hole, and the movable block is movable relative to the fixed part to drive the latch to move along the extension direction of the through hole; the transfer platform or the transfer carrier has a insertion hole, in the locked position, one end of the latch extends out of the through hole and is inserted into the insertion hole, and in the unlocked position, one end of the latch moves out of the insertion hole and enters the through hole.

[0014] In the embodiment, the latch and the insertion hole are used to lock and unlock the transfer platform and the transfer carrier, which can improve the stability of the locking of the transfer carrier and the transfer platform, and reduce the possibility of accidental falling of the transfer carrier. On the other hand, in the unlocked state, one end of the latch enters the through hole, so as to avoid the transfer carrier and improve the smoothness of the sliding of the transfer carrier along the guide rail, thereby improving the reliability of the transfer assembly.

[0015] In some embodiments, the movable block is rotatably connected with the latch and is rotatable relative to the fixed part to switch between the locked position and the unlocked position, the movable block has a first side wall and a second side wall, the distance from the first side wall to the rotation axis of the movable block is less than the distance from the second side wall to the rotation axis of the movable block, in the locked position, the first side wall abuts against the fixed part, and in the unlocked position, the second side wall abuts against the fixed part.

[0016] In the embodiment, the locking member can be switched between the locking position and the unlocking position by pushing the movable block to rotate, without pulling the movable block, so that the operation is simple and easy to implement by using a tool, and the use convenience of the transfer assembly is improved. On the other hand, the movable block can be relatively stably kept in the unlocking position, so that the possibility of the movable block moving accidentally during the sliding of the transfer carrier and causing the sliding of the transfer carrier to be blocked is reduced, and the reliability of the transfer assembly is improved.

[0017] In some embodiments, the insertion hole is arranged on the top surface of the transfer platform, the movable part is connected to the transfer carrier, the through hole extends along the height direction of the transfer platform, the rotation axis of the movable block is parallel to the second direction, the first direction intersects the second direction, and the first direction and the second direction are both perpendicular to the height direction of the transfer platform, the transfer carrier has a fork channel extending along the first direction and a fork inlet communicating with the fork channel, and the movable block is located in the fork channel and on the side away from the fork inlet.

[0018] In the embodiment, the fork carrying the battery device can enter the fork channel through the fork inlet, so that the battery device is placed on the transfer carrier. Since the movable block is located in the fork channel and on the side away from the fork inlet, during actual use, after the placement operation of the battery device is completed, the fork can be directly operated to push the movable block to rotate, so that the unlocking operation is completed, and thus the unlocking speed is improved, and the response speed of the fire-fighting treatment is improved.

[0019] In some embodiments, the transfer platform includes a plurality of guide rails arranged at intervals along the second direction, and the plurality of guide rails are in sliding fit with the bottom surface of the transfer carrier. The second direction intersects the first direction, and / or the guide rail includes a guide rail body and a plurality of pulleys arranged at intervals along the first direction on the guide rail body, and the pulleys are used to abut against the bottom surface of the transfer carrier.

[0020] In the embodiment, a plurality of guide rails are arranged, so that the stability of the transfer carrier during sliding is improved, and the possibility of the transfer carrier tipping over during sliding is reduced. In some other embodiments, the transfer platform can also be provided with only one guide rail.

[0021] In addition, in the embodiment, the pulleys can further improve the smoothness of the transfer carrier sliding along the transfer platform. In some other embodiments, pulleys can also be arranged on the bottom surface of the transfer carrier, or no pulleys are used.

[0022] In some embodiments, the guide rail is in sliding fit with the bottom surface of the transfer carrier, and the transfer platform further comprises at least one limiting piece arranged on the base, and the transfer carrier has a limiting groove on at least one side outer surface thereof in a second direction intersecting the first direction, the limiting groove extending downward from one end of the transfer carrier in the first direction to the other end, and the limiting piece is constrained in the limiting groove in the height direction of the transfer platform.

[0023] In the embodiment, the cooperation of the limiting piece and the limiting groove limits the upward bending amplitude of the tail of the transfer carrier during sliding, thereby improving the smoothness of the sliding of the transfer carrier and / or reducing the possibility of the battery device being detached from the transfer carrier, and further improving the use reliability of the transfer assembly.

[0024] In some embodiments, the limiting piece comprises a support column extending in the height direction of the transfer platform and a limiting wheel arranged on the side of the support column facing the transfer carrier and located in the limiting groove.

[0025] In the embodiment, the limiting piece comprises a limiting wheel, which can reduce the friction between the limiting piece and the limiting groove and avoid hindering the sliding of the transfer carrier as much as possible.

[0026] In some embodiments, the transfer platform further comprises a first sensor arranged on the base and / or the guide rail, the first sensor is located near the first end of the guide rail, and is used to detect whether the transfer carrier is in place.

[0027] In the embodiment, the first sensor is used to detect whether the transfer carrier is in place, and in actual use, the operator can monitor the actual working condition of the transfer carrier by means of the data of the first sensor. For example, in the case where no thermal runaway problem occurs, it is monitored whether the transfer carrier is located near the first end of the guide rail, and in the case where a thermal runaway problem occurs, it is monitored whether the transfer carrier smoothly slides away from the position. In this way, the use convenience and reliability of the transfer assembly are further improved.

[0028] In some embodiments, the first sensor comprises a plurality of pins, a part of the plurality of pins is used to transmit the signal detected by the first sensor, and the other part is used to power the first sensor.

[0029] In the embodiment, the power supply and data transmission of the first sensor are realized by the pins instead of cables, which can reduce the number of cables on the transfer platform, reduce the possibility of the cables winding around the transfer carrier and hindering the sliding of the transfer carrier, and improve the use reliability of the transfer mechanism.

[0030] In some embodiments, the transfer carrier comprises a body, the bottom surface of the body extends downward and is in sliding fit with the guide rail, and the top surface of the body extends in the horizontal direction or downward and is used to support the battery device.

[0031] In the embodiment, the top surface of the transfer carrier body extends in the horizontal direction, which can reduce the possibility of the battery device supported on the top surface of the body from sliding under the action of gravity. The top surface of the transfer carrier body extends obliquely, which can reduce the difficulty in manufacturing the body (the top surface will be approximately parallel to the bottom surface).

[0032] In some embodiments, the transfer carrier further comprises at least one positioning pin arranged on the top surface of the body, and the positioning pin is used to cooperate with the bottom surface of the battery device.

[0033] In the embodiment, the positioning pin cooperates with the bottom surface of the battery device, which can improve the positioning accuracy when the battery device is placed on the top surface of the body, thereby improving the use reliability of the transfer assembly.

[0034] In some embodiments, the transfer carrier further comprises a second sensor arranged on the positioning pin, and the second sensor is used to detect the connection state of the positioning pin and the bottom surface of the battery device.

[0035] In the embodiment, the second sensor is further arranged on the positioning pin, so that the operator can determine whether the battery device is placed in place by means of the data of the second sensor during actual operation, and then operate the locking member to unlock after determining that the battery device is placed in place, thereby reducing the possibility that the locking member is unlocked while the battery device is not placed in place.

[0036] In some embodiments, the number of positioning pins is at least two, and the positioning pins are arranged on opposite sides of the body along the second direction. In the projection plane perpendicular to the second direction, the projections of the at least two positioning pins form a gap along the first direction, and the second direction intersects the first direction.

[0037] In the embodiment, the arrangement mode of the positioning pins helps to improve the accuracy and reliability of the positioning of the battery device, thereby further improving the use reliability of the transfer assembly.

[0038] In some embodiments, the transfer carrier further comprises at least two limiting blocks arranged on the top surface of the body, and the at least two limiting blocks are arranged on opposite ends of the body along the first direction and are used to abut against the battery device.

[0039] In the embodiment, the limiting blocks are additionally arranged, so that the possibility of the battery device from sliding under the action of gravity can be further reduced. In addition, in the above-mentioned embodiment provided with the positioning pin and the second sensor, the pressure on the positioning pin / second sensor from the battery device can be reduced, thereby prolonging the service life of the positioning pin and the second sensor.

[0040] In some embodiments, the transfer carrier further comprises at least two pads protruding from the top surface of the body, the at least two pads being respectively arranged at opposite ends of the body along a second direction intersecting the first direction, the pads being configured to abut against the bottom surface of the battery device.

[0041] In the embodiment, the pads are added to the body to protect the battery device to some extent, and reduce the possibility of the bottom surface of the battery device colliding with the transfer carrier during the process of placing the battery device on the transfer carrier, thereby reducing the loss.

[0042] In some embodiments, the body comprises: two bottom edge beams arranged at intervals along a second direction intersecting the first direction; at least one bottom cross beam, two ends of the bottom cross beam being respectively connected to the two bottom edge beams; and at least two support frames arranged on the top side of the two bottom edge beams.

[0043] In the embodiment, the body adopts a frame structure, so that the overall weight, manufacturing cost and manufacturing difficulty of the transfer carrier can be reduced.

[0044] In some embodiments, the bottom surface of the bottom edge beam is in sliding fit with the guide rail, and the bottom surface of the bottom cross beam is higher than the bottom surface of the bottom edge beam.

[0045] In the embodiment, the bottom surface of the bottom cross beam is higher than the bottom surface of the bottom edge beam, so that the related structures of the transfer platform on the bottom side of the transfer carrier can be avoided to some extent, and the sliding smoothness of the transfer carrier can be improved.

[0046] In some embodiments, the transfer carrier further comprises at least one buffer, the buffer being arranged on one side end surface of the body close to the second end of the guide rail.

[0047] In the embodiment, the buffer is arranged on the transfer carrier, which can play a buffering role when the transfer carrier encounters a fixed obstacle during sliding, thereby reducing the possibility of the transfer carrier and the battery device being damaged due to serious collision, and can also push away movable obstacles (such as movable safety doors of a battery swap station) when encountering the movable obstacles, so that the transfer carrier can continue to slide.

[0048] In some embodiments, the transfer assembly further comprises a cleaning assembly configured to clean the battery device placed on the transfer carrier when the transfer carrier is locked with the transfer platform.

[0049] It can be understood that in a place where a plurality of battery devices are stored, such as a battery swap station, the space arrangement is usually compact, and the battery devices need to be cleaned during storage, so a cleaning station needs to be arranged in the place to clean the battery devices. The fire-fighting structure of the embodiment is configured with a cleaning assembly, so that in the case where there is no heat runaway problem, the transfer assembly can also serve as a cleaning station for the battery devices, saving internal space of the place.

[0050] A second aspect of the embodiment of the present disclosure provides a battery swap station, comprising: a battery compartment having a fire-fighting outlet; a safety door rotatably connected with the battery compartment to open or close the fire-fighting outlet; and the transfer assembly of the first aspect of the embodiment of the present disclosure, arranged in the battery compartment, wherein the safety door is located on the downstream side of the fire-fighting device along the first direction, and the safety door can be pushed open by the transfer carrier during the sliding stroke of the guide rail to reach outside the battery compartment through the fire-fighting outlet.

[0051] In the battery swap station of the embodiment, the transfer assembly can transfer the heat runaway battery device outside the battery compartment, so that the fire-fighting purpose can be achieved while minimizing the damage to the structure of the battery device, thereby reducing the loss.

[0052] Further, the transfer assembly of the embodiment of the present disclosure is provided with a downwardly inclined guide rail and a transfer carrier slidingly matched with the guide rail, so that after the locking member unlocks the transfer carrier from the transfer platform, the transfer carrier will slide along the guide rail under the action of gravity to realize the transfer of the battery device. This transfer mode is simple in structure and high in reliability.

[0053] In some embodiments, the transfer carrier has a fork channel and a fork inlet communicating with the fork channel, and the locking member is located in the fork channel. The battery swap station further comprises: a fork for entering the fork channel through the fork inlet to place the heat runaway battery device in the battery compartment on the transfer carrier of the transfer vehicle, and for applying a force to the locking member to unlock the transfer carrier of the transfer vehicle from the transfer platform.

[0054] In the embodiment, the carrying of the battery device and the unlocking of the locking member can be realized by one device, i.e. the fork, so that the operation steps can be simplified and the response speed of fire-fighting processing can be improved. BRIEF DESCRIPTION OF DRAWINGS

[0079] In the description of the embodiments of the present disclosure, unless specifically defined and limited otherwise, the technical term "contact" should be understood in a broad sense, which can be direct contact or contact through an intermediate medium layer, which can be contact between two objects in contact without interaction force, or contact between two objects in contact with interaction force.

[0080] The transport assembly of the embodiments of the present disclosure is suitable for transporting battery devices. The battery device mentioned in the embodiments of the present disclosure can include one or more battery cell assemblies for providing voltage and capacity. The battery cell assembly can include a plurality of battery cells connected in series, parallel or mixed connection through busbar components.

[0081] In some embodiments, the battery cell assembly is usually formed by arranging a plurality of battery cells.

[0082] As an example, the battery cell assembly can be a battery module, which is formed by arranging and fixing a plurality of battery cells into an independent module. As an example, the battery module can be formed by bundling a plurality of battery cells with a cable tie.

[0083] In some embodiments, the battery device can be a battery pack, which includes a box body and one or more battery cell assemblies accommodated in the box body.

[0084] As an example, the battery cell assembly can be a battery module, which can be accommodated in the box body by fixing the battery module in the box body.

[0085] As an example, the battery cell assembly can also be accommodated in the box body by directly fixing a plurality of battery cells in the box body.

[0086] As an example, the box can include a first box and a second box. The first box and the second box are buckled so that an inside of the box forms a closed space to accommodate the battery monomer assembly. The closed here means covered or closed, which can be sealed or unsealed. The first box can be a top cover or a bottom plate.

[0087] As an example, the box can include a top cover, a frame and a bottom plate. The top cover and the bottom plate are connected with the frame respectively, so that an inside of the box forms a closed space to accommodate the battery monomer assembly.

[0088] In some embodiments, the box can be part of the chassis structure of the vehicle. For example, part of the box can be at least part of the floor of the vehicle, or part of the box can be at least part of the cross beam and the longitudinal beam of the vehicle.

[0089] Places such as battery swap stations, battery warehouses, and battery production workshops that may store a plurality of battery devices need to be equipped with fire-fighting mechanisms to timely perform fire-fighting treatment when the battery device is in thermal runaway, and to avoid the spread of a single battery device thermal runaway to the remaining battery devices as much as possible.

[0090] The fire-fighting treatment method used in the related art is to sink the battery device in thermal runaway into a water tank, which will cause the battery device to be scrapped as a whole.

[0091] However, with the development of technology, the safety performance of the battery device has been improved, and the thermal runaway problem may be limited to one or a few battery monomers of the battery device and has not spread to all battery monomers. The battery monomers that have not been affected still have recycling value, and even the possibility of reuse. In this case, the above-mentioned fire-fighting treatment solution will cause the loss to be magnified.

[0092] On the other hand, in order to improve safety performance, the device for monitoring the thermal runaway problem of the battery device usually has high sensitivity, and there is a possibility of misjudgment. In the case of misjudgment, the above-mentioned fire-fighting treatment solution will also cause the loss to be magnified.

[0093] To solve the above problems, the transfer assembly of the embodiments of the present disclosure is proposed. The transfer assembly of the embodiments of the present disclosure includes a transfer platform, a transfer carrier and at least one locking piece. The transfer platform includes a base and at least one guide rail provided on the base. In the first direction, the guide rail has opposite first and second ends, and the guide rail is downwardly inclined from the first end to the second end. The transfer carrier is used to transfer the battery device, and the transfer carrier is in sliding fit with the guide rail. The at least one locking piece is used to lock or unlock the transfer carrier and the transfer platform.

[0094] The transport assembly of the embodiments of the present disclosure adopts a transport manner to perform fire-fighting treatment on the battery device, so that the fire-fighting purpose can be achieved while the damage to the structure of the battery device is reduced as much as possible, thereby reducing the loss.

[0095] Further, the transport assembly of the embodiments of the present disclosure is provided with a downwardly inclined guide rail and a transport carrier in sliding cooperation with the guide rail, so that after the locking member unlocks the transport carrier from the transport platform, the transport carrier will slide along the guide rail under the action of gravity to realize the transport of the battery device. This transport manner has simple structure and high reliability.

[0096] Referring to FIGS. 1-4, the transport assembly of the embodiments of the present disclosure includes a transport platform 1, a transport carrier 2, and at least one locking member 3. The transport platform 1 includes a base 11 and at least one guide rail 12 provided on the base 11. In a first direction, the guide rail 12 has opposite first and second ends 12a and 12b, and the guide rail 12 is inclined downward from the first end 12a to the second end 12b. The transport carrier 2 is used to transport a battery device 200, and the transport carrier 2 is in sliding cooperation with the guide rail 12. The at least one locking member 3 is used to lock or unlock the transport carrier 2 from the transport platform 1.

[0097] The base 11 mainly serves to support and fix the guide rail 12, and its specific structure is not limited. Those skilled in the art can determine the specific structure according to the actual use requirements and the actual installation environment of the transport platform 1, which is not limited.

[0098] The first direction can be a direction intersecting the height direction of the transport platform 1. As an example, the first direction can be perpendicular to the height direction of the transport platform 1. More specifically, the first direction can be substantially parallel to the length direction or the width direction of the transport carrier 2. In comparison, the first direction parallel to the length direction of the transport carrier 2 helps to reduce the overall size of the transport platform 1.

[0099] The at least one guide rail 12 is provided on the base 11, for example, on the top side of the base 11. The specific angle of inclination of the guide rail 12 from the first end 12a to the second end 12b is not limited. The inclination angle of the guide rail 12 will affect the speed and stability of the transport carrier 2 sliding along the guide rail 12, and those skilled in the art can determine the specific angle according to the actual use requirements. As an example, the included angle between the guide rail 12 from the first end 12a to the second end 12b and the horizontal plane can be 1°, 2°, 3°, 5°, 10°, 15°, etc.

[0100] The specific number of guide rails 12 is not limited, and one guide rail 12 can be provided or multiple guide rails 12 can be provided. When the number of guide rails 12 is multiple, the multiple guide rails 12 can simultaneously slide with one side surface of the transfer carrier 2 (such as the bottom surface of the transfer carrier 2), or the multiple guide rails 12 can respectively slide with different surfaces of the transfer carrier 2. The inclination angles of the multiple guide rails 12 can be the same or can have a certain deviation, such as a deviation of less than or equal to 0.1°, less than or equal to 0.2°, or less than or equal to 0.5°, and the like, as long as the transfer carrier 2 can slide along the multiple guide rails 12.

[0101] The transfer carrier 2 is used to carry the battery device 200, and the specific structure of the transfer carrier 2 is not limited as long as the transfer carrier 2 can carry the battery device 200 and slide with the guide rail. As an example, the transfer carrier 2 can be a frame body structure formed by splicing multiple beam structures, or the transfer carrier 2 can be a box structure formed by connecting multiple plate structures, and the like.

[0102] In actual use, the transfer carrier 2 can be connected with the battery device 200 to drive the battery device 200 to move, so as to realize the transfer of the battery device 200. As an example, the top side of the transfer carrier 2 can have a support surface, and the battery device 200 can be fixed on the support surface, or the inside of the transfer carrier 2 can form a transfer carrier 2 for accommodating the battery device 200.

[0103] The specific manner in which the transfer carrier 2 slides with the guide rail 12 is not limited. For example, the guide rail 12 can include a pulley 122 structure, and one side surface of the transfer carrier 2 can abut against the pulley 122 structure. Alternatively, the guide rail 12 can include a sliding groove structure, and the transfer carrier 2 can be provided with a pulley 122 structure on the corresponding surface, and the pulley 122 structure can be in the sliding groove structure. Alternatively, the guide rail 12 can be a track structure, and the transfer carrier 2 can be provided with a sliding groove, and a portion of the track structure can be located in the sliding groove.

[0104] The transfer carrier 2 can be configured to slide from the first end 12a to the second end 12b of the guide rail 12 and disengage from the second end 12b of the guide rail 12. Alternatively, the transfer carrier 2 can be configured to slide from the first end 12a to the second end 12b of the guide rail 12 and be stopped at the second end 12b of the guide rail 12. Those skilled in the art can specifically set according to the actual use requirement, as long as the transfer carrier 2 can transfer the thermal runaway battery to the desired safe position.

[0105] The locking member 3 is used to lock or unlock the transfer carrier 2 and the transfer platform 1. Here, "locking the transfer carrier 2 and the transfer platform 1" specifically means that the transfer carrier 2 cannot slide relative to the transfer platform 1 in the extension direction of the guide rail 12 (without excluding the possibility that the transfer carrier 2 can move relative to the transfer platform 1 in other directions), and "unlocking the transfer carrier 2 and the transfer platform 1" specifically means that the transfer carrier 2 can at least slide relative to the transfer platform 1 in the extension direction of the guide rail 12 (without excluding the possibility that the transfer carrier 2 cannot move relative to the transfer platform 1 in other directions).

[0106] The specific structure of the locking member 3 is not limited as long as it can achieve the above locking and unlocking functions.

[0107] The specific number of the locking member 3 is not limited, which can be one or multiple. In the case of multiple locking members 3, the multiple locking members 3 can be distributed along a second direction, which intersects the first direction, so as to improve the reliability of locking.

[0108] In actual use, when the battery device 200 does not have a thermal runaway problem, the locking member 3 can lock the transfer carrier 2 at a position close to the first end 12a of the guide rail 12, and when the battery device 200 has a thermal runaway problem, the transfer carrier 2 can be used to transfer the battery device 200 with thermal runaway, and then the transfer carrier 2 and the transfer platform 1 are unlocked, so that the transfer carrier 2 slides along the guide rail 12 under the action of gravity, thereby transferring the battery device 200 with thermal runaway to a safe position.

[0109] The transfer assembly of the embodiment adopts a transfer mode to perform fire-fighting treatment on the battery device 200, so that the fire-fighting purpose can be achieved while minimizing the damage to the structure of the battery device 200, thereby reducing the loss.

[0110] Further, the transfer assembly of the embodiment of the disclosure is provided with a downwardly inclined guide rail 12 and a transfer carrier 2 in sliding cooperation with the guide rail 12, so that after the locking member 3 unlocks the transfer carrier 2 and the transfer platform 1, the transfer carrier 2 will be able to slide along the guide rail 12 under the action of gravity to achieve the transfer of the battery device 200, and this transfer mode has a simple structure and high reliability.

[0111] In some embodiments, referring to FIGS. 5-7, the locking member 3 includes a fixed part 31 and a movable part 32, the fixed part 31 is arranged on one of the transfer platform 1 and the transfer carrier 2, and the movable part 32 is movably connected with the fixed part 31 to switch between the locking position and the unlocking position by moving relative to the fixed part 31. In the locking position, the movable part 32 is connected to the other one of the transfer platform 1 and the transfer carrier 2, and in the unlocking position, the movable part 32 is disconnected from the other one of the transfer platform 1 and the transfer carrier 2.

[0112] The specific structure of the fixed part 31 and the movable part 32 is not limited. For example, the fixed part 31 is connected to the transfer carrier 2, and the movable part 32 is connected to the transfer platform 1 in the locked position. The fixed part 31 can include a block structure, a plate structure, etc., which can be connected to the transfer carrier 2 by structures such as bolts, etc. The movable part 32 can include, for example, a block structure, a latch 322 structure, etc., and in the locked position, the movable part 32 can abut against the transfer platform 1 (such as abutting against one side surface of the guide rail 12) or be inserted into a structure of the transfer platform 1. In this way, the movable part 32 is connected to the transfer platform 1 on one side and connected to the transfer carrier 2 through the fixed part 31 on the other side, thereby achieving the locking of the transfer platform 1 and the transfer carrier 2. In the unlocked position, the movable part 32 is disconnected from the transfer platform 1. At this time, the movable part 32 can continue to be connected to the fixed part 31, or the movable part 32 can also be disconnected from the fixed part 31. Regardless of which scheme is used, the transfer platform 1 and the transfer carrier 2 can be unlocked.

[0113] The specific movement mode of the movable part 32 relative to the fixed part 31 is not limited, such as translation, rotation, or a combination of the above movement modes, etc. Those skilled in the art can select the movement mode of the movable part 32 and the fixed part 31 according to the actual desired movement mode.

[0114] In this embodiment, the fixed part 31 and the movable part 32 cooperate to achieve the locking and unlocking of the transfer carrier 2 and the transfer platform 1. In this way, the structure of the locking member 3 can be simplified, and the operation difficulty of the locking member 3 during locking and unlocking can be reduced. This facilitates the quick unlocking of the transfer carrier 2 and the transfer platform 1 when a thermal runaway problem occurs, and improves the reliability of the transfer assembly.

[0115] In some embodiments, referring to FIGS. 5-7, the movable part 32 includes a movable block 321 and a latch 322, the fixed part 31 has a through hole 31a, the latch 322 is inserted into the through hole 31a, and the movable block 321 can move relative to the fixed part 31 to drive the latch 322 to move along the extension direction of the through hole 31a; the transfer platform 1 or the transfer carrier 2 has a insertion hole 1a, in the locked position, one end of the latch 322 extends from the through hole 31a and is inserted into the insertion hole 1a, and in the unlocked position, one end of the latch 322 moves out of the insertion hole 1a and enters the through hole 31a.

[0116] It should be noted that the end of the latch 322 entering the through hole 31a specifically refers to the end face of the end of the latch 322 not exceeding the face where the opening of the through hole 31a is located along the extension direction of the latch 322.

[0117] The specific connection mode of the movable block 321 and the latch 322 is not limited, such as movable connection or relatively fixed connection.

[0118] The manner in which the movable block 321 moves relative to the fixed portion 31 is not limited, as long as it can drive the pin 322 to move along the extension direction of the through hole 31a when the movable block 321 moves relative to the fixed portion 31. As an example, the sliding block can translate relative to the fixed portion 31 along the extension direction of the through hole 31a to drive the pin 322 to move along the axial direction of the fixed portion 31. Alternatively, the sliding block can move in other manners, as long as the connection point between the movable block 321 and the pin 322 moves along the extension direction of the through hole 31a during movement.

[0119] In this embodiment, the pin 322 and the through hole 1a are matched to lock and unlock the transfer platform 1 and the transfer carrier 2. This matching manner can improve the stability of the locking of the transfer carrier 2 and the transfer platform 1, and reduce the possibility of accidental falling of the transfer carrier 2. On the other hand, in the unlocked state, one end of the pin 322 enters the inside of the through hole 31a, so as to avoid the transfer carrier 2 and improve the smoothness of the sliding of the transfer carrier 2 along the guide rail 12, thereby improving the reliability of the transfer assembly.

[0120] In some embodiments, referring to FIGS. 5 and 7, the movable block 321 is rotationally connected with the pin 322 and can rotate relative to the fixed portion 31 to switch between the locked position and the unlocked position. The movable block 321 has a first side wall 3211 and a second side wall 3212, the distance from the first side wall 3211 to the rotation axis of the movable block 321 is less than the distance from the second side wall 3212 to the rotation axis of the movable block 321. In the locked position, the first side wall 3211 abuts against the fixed portion 31, and in the unlocked position, the second side wall 3212 abuts against the fixed portion 31.

[0121] The specific manner in which the movable block 321 is rotationally connected with the rotation shaft is not limited, and the rotation shaft can be used to achieve the rotational connection.

[0122] The specific matching manner between the movable block 321 and the fixed portion 31 is not limited. As an example, the first side wall 3211 and the second side wall 3212 can be straight walls, and an arc-shaped wall can be formed between the first side wall 3211 and the second side wall 3212. The movable block 321 can be rotationally connected with the fixed portion 31 by means of the sliding fit between the arc-shaped wall and the surface of the fixed portion 31 to rotate from the position where the first side wall 3211 abuts against the fixed portion 31 (the locked position) to the position where the second side wall 3212 abuts against the fixed portion 31 (the unlocked position). Of course, the first side wall 3211 and the second side wall 3212 can also have other structural forms, such as arc-shaped walls, and the like, which are not limited.

[0123] Referring to FIG. 7, since the distance D1 from the first side wall 3211 to the rotation axis of the movable block 321 (i.e., the connection between the movable block 321 and the pin 322) is smaller than the distance D2 from the second side wall 3212 to the rotation axis of the movable block 321, during the rotation of the movable block 321 from the position where the first side wall 3211 abuts against the fixed portion 31 (the locked position) to the position where the second side wall 3212 abuts against the fixed portion 31 (the unlocked position), the connection between the movable block 321 and the pin 322 will move towards the direction away from the fixed portion 31, thereby driving the pin 322 to move along the extension direction of the insertion hole 1a.

[0124] Those skilled in the art can understand that, assuming that the distance between the end face of the end of the pin 322 extending out of the through hole 31a and the face where the opening of the through hole 31a is located is D3 in the locked position, in order to realize that the end of the pin 322 enters the through hole 31a in the unlocked position, it is necessary to satisfy D2-D1≥D3.

[0125] In the embodiment, the switching of the locking member 3 between the locked position and the unlocked position can be realized by only pushing the movable block 321 to rotate, without pulling the movable block 321, and the operation mode is relatively simple and easy to realize by means of a tool, so that the use convenience of the transfer assembly can be improved. On the other hand, the movable block 321 can be relatively stably kept in the unlocked position, reducing the possibility that the transfer carrier 2 is blocked from sliding due to accidental movement of the movable block 321 during the sliding of the transfer carrier 2, and improving the reliability of the transfer assembly.

[0126] In some embodiments, referring to FIGS. 1 and 5, the insertion hole 1a is arranged on the top surface of the transfer platform 1, the movable portion 32 is connected to the transfer carrier 2, the through hole 31a extends along the height direction of the transfer platform 1, the rotation axis of the movable block 321 is parallel to the second direction, the first direction intersects the second direction, and both the first direction and the second direction are perpendicular to the height direction of the transfer platform 1. The transfer carrier 2 has a fork channel 2a extending along the first direction and a fork inlet 2b communicating with the fork channel 2a, and the movable block 321 is located in the fork channel 2a and on the side away from the fork inlet 2b.

[0127] The first direction and the second direction can form any suitable angle, and no limitation is made in this regard. As an example, the first direction and the second direction are orthogonal, and one of the first direction and the second direction is the length direction of the transfer carrier 2, and the other is the width direction of the transfer carrier 2.

[0128] The fork channel 2a and the fork inlet 2b are used for the entry of a fork, which is a device for transferring the battery device 200 and is well known to those skilled in the art, and no limitation is made to the specific structure thereof.

[0129] In the embodiment, the fork carrying the battery device 200 can enter the fork channel 2a through the fork inlet 2b, so as to place the battery device 200 on the transfer carrier 2. Since the movable block 321 is located in the fork channel 2a and away from the fork inlet 2b, in actual use, after the placement of the battery device 200 is completed, the fork can be directly operated to push the movable block 321 to rotate, so as to complete the unlocking operation. In this way, the unlocking speed is improved, and the response speed of the fire-fighting treatment is further improved.

[0130] In some embodiments, referring to FIG. 1, the transfer platform 1 includes a plurality of guide rails 12 spaced apart along the second direction, and each of the plurality of guide rails 12 is in sliding fit with the bottom surface of the transfer carrier 2. The second direction intersects the first direction.

[0131] For example, the transfer platform 1 can specifically include two guide rails 12, and each of the two guide rails 12 is in sliding fit with the opposite two side edge regions of the bottom surface of the transfer carrier 2 along the second direction. Of course, the transfer platform 1 can also include more guide rails 12.

[0132] In the embodiment, a plurality of guide rails 12 are provided, so that the stability of the transfer carrier 2 during sliding can be improved, and the possibility of the transfer carrier 2 falling during sliding can be reduced. In some other embodiments, the transfer platform 1 can also be provided with only one guide rail 12.

[0133] In some embodiments, referring to FIG. 1, the guide rail 12 includes a guide rail body 121 and a plurality of pulleys 122 spaced apart along the first direction on the guide rail body 121, and the pulley 122 is used to abut against the bottom surface of the transfer carrier 2.

[0134] The specific structure of the guide rail body 121 is not limited. For example, the guide rail body 121 can have a cavity corresponding to the pulley 122, and the cavity is open at the top side of the guide rail body 121. The pulley 122 is arranged in the cavity and extends out of the cavity through the opening to abut against the bottom surface of the transfer carrier 2.

[0135] The bottom surface of the transfer carrier 2 can be provided with a sliding groove structure, and the pulley 122 can be located in the sliding groove structure. Alternatively, the pulley 122 can directly abut against the bottom surface of the transfer carrier 2.

[0136] In the embodiment, the pulley 122 can further improve the smoothness of the transfer carrier 2 sliding along the transfer platform 1. In some other embodiments, the pulley 122 can also be arranged on the bottom surface of the transfer carrier 2, or the pulley 122 is not used.

[0137] In some embodiments, referring to FIG. 3, the guide rail 12 is in sliding fit with the bottom surface of the transfer carrier 2, and the transfer platform 1 further comprises at least one limiting piece 13 arranged on the base 11, the transfer carrier 2 has a limiting groove 2c on at least one side surface thereof along a second direction intersecting the first direction, the limiting groove 2c extends downward from one end of the transfer carrier 2 along the first direction to the other end, and the limiting piece 13 is constrained in the limiting groove 2c along the height direction of the transfer platform 1.

[0138] It can be understood that, since the guide rail 12 is downwardly inclined and in sliding fit with the bottom surface of the guide rail 12, when the transfer carrier 2 slides along the guide rail 12, the center of gravity of the battery device 200 is relatively close to the front part (the side close to the second end 12b of the guide rail 12 during sliding), and the tail part (the side close to the first end 12a of the guide rail 12 during sliding) of the transfer carrier 2 may be raised. The raising of the tail part of the transfer carrier 2 may on one hand cause the sliding speed of the transfer carrier 2 to decrease or even be unable to slide, and on the other hand may cause the battery device 200 to be detached from the transfer carrier 2.

[0139] Based on the above problems, the limiting piece 13 and the limiting groove 2c are arranged in the present embodiment, the limiting groove 2c is formed on the side surface of the transfer carrier 2 along the second direction, and the limiting piece 13 is constrained in the limiting groove 2c along the height direction of the transfer platform 1. In this way, when the tail part of the transfer carrier 2 tends to be raised, the limiting piece 13 can limit the actual raising amplitude of the tail part of the transfer carrier 2.

[0140] The inclination angle of the limiting groove 2c can be the same as the inclination angle of the guide rail 12, or can have a certain deviation, such as a deviation of less than or equal to 0.1°, less than or equal to 0.2°, or less than or equal to 0.5°, etc.

[0141] The specific structure of the limiting groove 2c and the limiting piece 13 is not limited, as long as the limiting groove 2c can constrain the limiting piece 13 along the height direction.

[0142] The number of the limiting pieces 13 can be one or multiple, and no limitation is made thereto. In the case where the number of the limiting pieces 13 is multiple, the multiple limiting pieces 13 can be distributed along the first direction, so that when the transfer carrier 2 slides to any position along the guide rail 12, at least one limiting piece 13 is constrained in the limiting groove 2c.

[0143] In the present embodiment, the limiting piece 13 and the limiting groove 2c are matched to limit the raising amplitude of the tail part of the transfer carrier 2 during sliding, so as to improve the smoothness of the sliding of the transfer carrier 2 and / or reduce the possibility of the battery device 200 being detached from the transfer carrier 2, thereby improving the use reliability of the transfer assembly.

[0144] In some embodiments, still referring to FIG. 3, the limiting member 13 comprises a support 131 extending along the height direction of the transfer platform 1 and a limiting wheel 132 arranged on the side of the support 131 facing the transfer carrier 2 and located in the limiting groove 2c.

[0145] For example, the bottom end of the support 131 can be connected to the side surface of the guide rail 12 in the second direction, or the support 131 can be directly connected to the top surface of the base 11, and the limiting wheel 132 can be arranged at the top end of the support 131.

[0146] In this embodiment, the limiting member 13 comprises the limiting wheel 132, which can reduce the friction between the limiting member 13 and the limiting groove 2c and avoid hindering the sliding of the transfer carrier 2 as much as possible.

[0147] In some embodiments, referring to FIG. 4, the transfer carrier 2 further comprises a first sensor 14 arranged on the base 11 and / or the guide rail 12, and the first sensor 14 is located near the first end 12a of the guide rail 12 and is used to detect whether the transfer carrier 2 is in place.

[0148] The specific structure of the first sensor 14 is not limited, such as a sensor known to those skilled in the art, as long as it can detect whether the transfer carrier 2 is in place. Here, "detecting whether the transfer carrier 2 is in place" specifically refers to detecting whether the transfer carrier 2 is in the position near the first sensor 14, that is, detecting whether the transfer carrier 2 is located near the first end 12a of the guide rail 12.

[0149] The first sensor 14 can be arranged on the base 11, such as the top surface of the base 11, or the first sensor 14 can be arranged on the guide rail 12, such as the top surface of the guide rail 12 or the cross section of the first end 12a. Alternatively, part of the first sensor 14 is arranged on the base 11 and part of the first sensor 14 is arranged on the guide rail 12.

[0150] In this embodiment, the first sensor 14 is used to detect whether the transfer carrier 2 is in place. In actual use, the operator can monitor the actual working condition of the transfer carrier 2 by means of the data of the first sensor 14, such as monitoring whether the transfer carrier 2 is located near the first end 12a of the guide rail 12 in the case of no thermal runaway problem, and monitoring whether the transfer carrier 2 smoothly slides away from the position in the case of thermal runaway problem. In this way, the use convenience and reliability of the transfer assembly are further improved.

[0151] Referring to FIGS. 1-4, the first sensor 14 comprises a plurality of pins (not shown in the drawings), part of which is used to transmit the signal detected by the first sensor 14, and the other part is used to power the first sensor 14.

[0152] The specific structure of the top pin can refer to the related technology in the art, and is not limited.

[0153] In this embodiment, the power supply and data transmission of the first sensor 14 are realized through the top pin instead of through a cable, so that the number of cables on the transfer platform 1 can be reduced, the possibility that the transfer carrier 2 is blocked by the winding of the cable can be reduced, and the use reliability of the transfer mechanism can be improved.

[0154] In some embodiments, referring to FIGS. 1 and 8, the transfer carrier 2 comprises a body 21, the bottom surface of the body 21 extends downwardly and slidably cooperates with the guide rail 12, and the top surface of the body 21 extends horizontally or downwardly and is used to support the battery device 200.

[0155] The specific structure of the body 21 is not limited, as mentioned above, the body 21 can be a box-shaped structure or a frame-shaped structure, etc.

[0156] The specific manner of the sliding cooperation between the bottom surface of the body 21 and the guide rail 12 can refer to the description of the related part in the above, and is not limited.

[0157] The angle of the downwardly extending bottom surface of the body 21 can be the same as the angle of the guide rail 12, or there can be a certain deviation, such as a deviation less than or equal to 0.1°, less than or equal to 0.2°, or less than or equal to 0.5°, etc.

[0158] In the embodiment in which the top surface of the body 21 extends downwardly, the angle of the downwardly extending top surface can be the same as the angle of the downwardly extending bottom surface, or there can be a certain deviation, such as a deviation less than or equal to 0.1°, less than or equal to 0.2°, or less than or equal to 0.5°, etc.

[0159] In this embodiment, the horizontal extension of the top surface of the body 21 of the transfer carrier 2 can reduce the possibility that the battery device 200 supported on the top surface of the body 21 slides down under the action of gravity, and the downward extension of the top surface of the body 21 of the transfer carrier 2 can reduce the difficulty in the preparation of the body 21 (the top surface and the bottom surface will be approximately parallel).

[0160] In some embodiments, referring to FIGS. 1-4, the transfer carrier 2 further comprises at least one positioning pin 22 arranged on the top surface of the body 21, and the positioning pin 22 is used to cooperatively connect with the bottom surface of the battery device 200.

[0161] The specific structure of the positioning pin 22 is not limited, which can be a pin-shaped structure, for example, referring to FIG. 9, the bottom surface of the battery device 200 can be provided with a positioning hole 200a, and the positioning pin 22 can be inserted into the positioning hole 200a in the height direction.

[0162] In the embodiment, the positioning pin 22 is connected with the bottom surface of the battery device 200, so that the positioning accuracy of the battery device 200 placed on the top surface of the body 21 is improved, and the use reliability of the transfer assembly is improved.

[0163] In some embodiments, the transfer carrier 2 further comprises a second sensor (not shown in the figure) arranged on the positioning pin 22, and the second sensor is used to detect the connection state of the positioning pin 22 and the bottom surface of the battery device 200.

[0164] The specific structure of the second sensor is not limited, which can be a well-known in-place sensor to the person skilled in the art, and the second sensor can be arranged inside the positioning pin 22 or on the outer surface of the positioning pin 22, which is not limited.

[0165] In the embodiment, the second sensor is further arranged on the positioning pin 22, so that in the actual operation process, the operator can judge whether the battery device 200 is placed in place by means of the data of the second sensor, and then operate the locking piece 3 to unlock after determining that the battery device 200 is placed in place, thereby reducing the possibility that the locking piece 3 is unlocked while the battery device 200 is not placed in place.

[0166] In some embodiments, referring to FIG. 1 and FIG. 8, the number of the positioning pins 22 is at least two, and the at least two positioning pins 22 are arranged on opposite sides of the body 21 along the second direction, and the projections of the at least two positioning pins 22 along the first direction form intervals on the projection plane perpendicular to the second direction, and the second direction intersects the first direction.

[0167] In the embodiment, the projections of the at least two positioning pins 22 along the first direction form intervals, that is, the at least two positioning pins 22 are not only distributed on opposite sides of the body 21 along the second direction, but also distributed along the first direction.

[0168] In the embodiment, the arrangement mode of the positioning pin 22 helps to improve the positioning accuracy and reliability of the battery device 200, thereby further improving the use reliability of the transfer assembly.

[0169] In some embodiments, the transfer carrier 2 further comprises at least two limiting blocks 23 arranged on the top surface of the body 21, and the at least two limiting blocks 23 are arranged on opposite ends of the body 21 along the first direction and used to abut against the battery device 200.

[0170] The specific structure of the limiting block 23 is not limited, for example, one side of the limiting block 23 towards the middle part of the body 21 can have a guide surface, and the direction from the top end to the bottom end of the guide surface is inclined towards the middle part of the body 21, so that the limiting block 23 can guide the battery device 200 during the placement process, thereby improving the placement success rate of the battery device 200.

[0171] In the embodiment, the limiting block 23 is additionally arranged, so that the possibility of the battery device 200 sliding under the action of gravity can be further reduced. In addition, in the above embodiment in which the positioning pin 22 and the second sensor are arranged, the pressure on the positioning pin 22 / second sensor from the battery device 200 can be reduced, and the service life of the positioning pin 22 and the second sensor can be prolonged.

[0172] In some embodiments, referring to FIGS. 1 and 8, the transfer carrier 2 further includes at least two pads 24 protruding from the top surface of the body 21, the at least two pads 24 being arranged at opposite ends of the body 21 along a second direction, the second direction intersecting the first direction, and the pads 24 being configured to abut against the bottom surface of the battery device 200.

[0173] The specific structure of the pads 24 is not limited. For example, the pads 24 can have a cuboid structure. The specific number of the pads 24 is not limited. For example, when the top surface of the body 21 is substantially rectangular, the pads 24 can be four, and are arranged at positions close to the four corners of the body 21.

[0174] The pads 24 are configured to abut against the bottom surface of the battery device 200, such as the side beams of the bottom surface of the battery device 200.

[0175] The pads 24 can be made of a material having flexibility, such as rubber, so that the pads 24 can have better protection performance.

[0176] In the embodiment, by additionally arranging the pads 24, the battery device 200 can be protected to a certain extent, and the possibility of the bottom surface of the battery device 200 colliding with the transfer carrier 2 during the process of placing the battery device 200 on the transfer carrier 2 can be reduced, so that the loss can be reduced.

[0177] In some embodiments, referring to FIGS. 1 and 8, the body 21 includes two bottom edge beams 211 arranged at intervals along a second direction, the second direction intersecting the first direction, at least one bottom cross beam 212, two ends of the bottom cross beam 212 being connected to the two bottom edge beams 211, and at least two support frames 213 arranged at the top sides of the two bottom edge beams 211.

[0178] The specific structure and number of the bottom edge beams 211, the bottom cross beam 212, and the support frames 213 are not limited. For example, the number of the bottom edge beams 211 is two, the number of the bottom cross beam 212 is multiple, the multiple bottom cross beams 212 are arranged at intervals along the first direction, and the number of the support frames 213 is four, two support frames 213 being arranged at the top side of each bottom edge beam 211, and the two support frames 213 corresponding to the bottom edge beam 211 being arranged at intervals along the first direction.
