DETAILED DESCRIPTION

[0031] Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, and not all of them. Based on the description of the present invention, all other embodiments derived by persons of ordinary skill in the art without inventive effort are also within the scope of protection of the present invention.

[0032] Unless otherwise specified or limited, the terms "disposed," "installed," and "connected" should be interpreted broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms based on the specific circumstances.

[0033] The directions or positional relationships indicated by terms such as "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience and simplification of description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the utility model.

[0034] The terms "first," "second," "third," etc. are merely used to distinguish elements of similar nature and do not indicate or imply relative importance or a particular order.

[0035] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of elements other than the listed elements and may also include additional elements not specifically listed.

[0036] As attached Figure 1 As shown in the coordinate system in , for ease of understanding, direction D1 is defined as the first direction, direction D2 as the second direction, and direction D3 as the third direction, i.e., the up-down direction, with the direction indicated by the arrow being upward. This coordinate system is intended to illustrate the general positional relationship, connection relationship, or motion relationship of various components, and does not imply that the various components in the present invention must be arranged or connected strictly in accordance with this coordinate system. Those skilled in the art may flexibly adjust it according to actual needs.

[0037] As attached Figure 1 As shown, the battery pack fire protection transfer device for a battery swap station proposed by the present invention includes a main body 10 and a guide rail 20. The main body 10 is arranged outside the battery swap station and is combined with the attached Figure 3 The main body 10 includes a battery inlet 101 and a receiving cavity 102 . The battery inlet 101 is connected to the receiving cavity 102 . The battery inlet 101 is used to allow the thermal runaway battery pack to enter the receiving cavity 102 .

[0038] The guide rail 20 includes at least a first guide section 201 located in the battery swap station. The battery inlet 101 cooperates with the first guide section 201. The thermal runaway battery pack can be transported from the battery swap station to the main body 10 through the first guide section 201, and enter the accommodating cavity 102 through the battery inlet 101. The accommodating cavity 102 is used to accommodate fire-fighting media and thermal runaway battery packs. The fire-fighting medium can perform fire-fighting treatment on the thermal runaway battery pack in the accommodating cavity 102.

[0039] By arranging the main body 10 outside the battery swap station, fire-fighting treatment of the thermal runaway battery pack can be carried out outside the battery swap station, avoiding the problem of the battery pack flame or burning smoke spreading to the battery swap station. Through the cooperation of the main body 10 and the guide rail 20, the thermal runaway battery pack can be quickly sent to the main body 10 outside the battery swap station through the guide rail 20. Compared with the prior art that requires the fire-fighting box containing the thermal runaway battery to be transferred out of the battery swap station, there is no need to transfer the main body 10 with a larger volume and weight, which reduces the difficulty of operation and saves manpower. For some automatically controlled fire-fighting boxes, since electrical components are provided in the fire-fighting box, the wiring harness is difficult to remove and detach from the fire-fighting box during the transfer process, resulting in difficulty in transportation. The cooperation of the main body 10 and the guide rail 20 can effectively improve the efficiency of fire-fighting treatment and improve the overall safety of the battery swap station.

[0040] In one alternative, the firefighting medium is a firefighting liquid, which is used to immerse the thermally runaway battery pack in the accommodating cavity 102 to achieve firefighting isolation. In another alternative, the firefighting medium is firefighting sand, which is used to bury the thermally runaway battery pack in the accommodating cavity 102 to achieve firefighting isolation.

[0041] Preferably, firefighting liquid is used as the firefighting medium in the present invention. The main body 10 is provided with an injection port and a discharge port connected to the accommodating cavity 102. The firefighting liquid can enter the accommodating cavity 102 through the injection port, and the firefighting liquid can be discharged through the discharge port. Firefighting liquid is pre-stored in the accommodating cavity 102 to improve the efficiency of firefighting treatment.

[0042] In one example scenario, in conjunction with the Figure 1 To the attached Figure 3 The main body 10 includes a box body 11 and a cover body 12. The box body 11 includes the above-mentioned battery inlet 101 and accommodating cavity 102. The battery inlet 101 is arranged on one side of the box body 11 close to the guide rail 20 in the first direction. The thermal runaway battery pack can enter the accommodating cavity 102 through the battery inlet 101. The cover body 12 is connected to the upper end of the box body 11. The cover body 12 covers the top of the accommodating cavity 102. The accommodating cavity 102 can be selectively opened or closed by the cover body 12. The cover body 12 can play a fire isolation role, preventing the flame or smoke of the thermal runaway battery pack from spreading to the outside of the box body 11.

[0043] Exemplarily, the cover 12 is detachably connected to the box 11 , or the cover 12 is movably connected to the box 11 , and the battery pack after fire treatment can be taken out from the accommodating cavity 102 by removing the cover 12 or opening the cover 12 .

[0044] In one example scenario, in conjunction with the Figure 2 and attached Figure 3 The main body 10 includes a sealing member 13, which has an open state and a closed state relative to the battery inlet 101. Figure 3 1 is a structural diagram of the box body 11 when the sealing member 13 is in the open state. At this time, the sealing member 13 is located in the first position relative to the battery inlet 101. Figure 3 When the sealing member 13 is in the open state, the battery inlet 101 is opened and connects the accommodating cavity 102 and the outside of the box body 11. The thermal runaway battery pack can enter the accommodating cavity 102 through the battery inlet 101. Figure 2 1 is a structural diagram of the main body 10 when the sealing member 13 is in the closed state. At this time, the sealing member 13 is located at the second position relative to the battery inlet 101. Figure 2 When the sealing member 13 is in the closed state, the sealing member 13 is located at the battery inlet 101, sealing the battery inlet 101 to form a closed space inside the main body 10 to prevent the fire from spreading through the battery inlet 101 to the outside of the main body 10 and the battery swap station.

[0045] The cover 12 cooperates with the sealing member 13 to encapsulate the thermal runaway battery pack in the main body 10 for isolation. Since the thermal runaway battery pack is transported through the guide rail 20, if the length of the guide rail 20 is large, it may cause the fire to spread. Therefore, the main body 10 is arranged at a position close to the battery swap station, and the length of the guide rail 20 is reduced as much as possible. The cover 12 and the sealing member 13 are both closed, which can prevent the flame or smoke of the burning thermal runaway battery pack from entering the battery swap station, eliminating the fire hazard in the station caused by untimely thermal runaway treatment.

[0046] In an exemplary embodiment, the accommodating chamber 102 includes an upper chamber and a lower chamber, and the upper chamber and the lower chamber are distributed along the third direction and are connected. Figure 3 As shown, a support portion 14 is provided in the upper cavity, and the support portion 14 includes a accommodating space for accommodating a thermal runaway battery pack. The support portion 14 includes a locked state and an unlocked state. The support portion 14 cooperates with the sealing member 13. When the support portion 14 is in the locked state, the sealing member 13 is in the open state. The support portion 14 is located in the upper cavity, and the accommodating space is communicated with the battery inlet 101. The thermal runaway battery pack can enter the accommodating space through the battery inlet 101. The support portion 14 supports the thermal runaway battery pack. When the support portion 14 is in the unlocked state, the support portion 14 and the thermal runaway battery pack enter the lower cavity along the third direction, and the sealing member 13 is in the closed state.

[0047] As attached Figure 3 As shown, the main body 10 is provided with a mounting beam 103 at the upper end of the battery inlet 101. More specifically, the mounting beam 103 is connected to the box body 11. When the blocking member 13 is in the first position, the end of the blocking member 13 close to the battery inlet 101 in the first direction is movably connected to the mounting beam 103. Figure 4 The support portion 14 includes a supporting member 1401. When the support portion 14 is in the locked state, the blocking member 13 is located in the first position relative to the mounting beam 103, and the blocking member 13 is located above the support portion 14. The supporting member 1401 contacts the lower end of the blocking member 13 to support the blocking member 13.

[0048] When the support portion 14 is in the unlocked state, the support portion 14 falls into the lower cavity along the third direction, the supporting effect of the supporting member 1401 on the sealing member 13 disappears, and the sealing member 13 moves to the second position relative to the mounting beam 103, and blocks and closes the battery inlet 101. The sealing member 13 can cooperate with the support portion 14 to automatically close after the thermal runaway battery pack enters the main body 10, without the need for manual intervention, thereby improving the safety of the operation and having a good isolation effect to prevent the fire from spreading to the outside of the main body 10.

[0049] For example, in conjunction with Figure 5 and attached Figure 6 The sealing member 13 is connected to the mounting beam 103 via a first hinge 131 , so that the sealing member 13 can be flipped relative to the mounting beam 103 .

[0050] For example, when the blocking member 13 is located at the first position, Figure 2 and attached Figure 3 , the sealing member 13 is parallel to the cover 12 . When the sealing member 13 is located at the second position, the sealing member 13 is located at the battery inlet 101 and is perpendicular to the cover 12 .

[0051] For example, in conjunction with Figure 5 and attached Figure 6 The sealing member 13 is provided with a reinforcing rib 132 , which is used to increase the structural strength of the sealing member 13 .

[0052] Exemplarily, two supporting members 1401 are provided. When the sealing member 13 is located at the first position, the two supporting members 1401 are spaced apart and distributed at the lower end of the sealing member 13 along the second direction.

[0053] In an example scenario, as shown in the attached Figure 4As shown, the support portion 14 includes a base 141 and a functional frame 142. The base 141 and the functional frame 142 cooperate to form a storage space for accommodating a thermal runaway battery pack. The base 141 is used to contact the bottom of the thermal runaway battery pack and play a supporting role. The functional frame 142 is spaced apart in the second direction at the upper end of the base 141 and is connected to the upper end of the base 141. The base 141 is detachably installed in the main body 10 through the functional frame 142. The above-mentioned supporting member 1401 is arranged at the upper end of the functional frame 142.

[0054] For example, as shown in the attached Figure 4 As shown, the base 141 is provided with a plurality of hollow grooves 1411 extending vertically through the base 141. The provision of the hollow grooves 1411 allows the thermal runaway battery pack placed on the base 141 to quickly come into contact with the firefighting medium stored in the accommodating cavity 102, thereby improving firefighting efficiency. Optionally, the base 141 is formed by a plurality of connecting beams joined together to form a frame structure. The aforementioned hollow grooves 1411 are formed by joining the connecting beams. An appropriate number and specification of connecting beams can be selected to form the base 141 based on the battery specifications.

[0055] For example, as shown in the attached Figure 4 As shown, a stopper 1412 is provided on the side of the base 141 away from the battery inlet 101 in the first direction. The stopper 1412 extends along the third direction and protrudes from the upper end of the base 141. The stopper 1412 is used to contact the thermal runaway battery pack to limit the thermal runaway battery pack, which can prevent the thermal runaway battery pack from colliding with the box body 11 when entering the accommodation space, and can ensure that the thermal runaway battery pack is stably accommodated in the accommodation space without causing positional displacement in the first direction and causing it to fail to fall smoothly into the lower cavity.

[0056] In an example scenario, as shown in the attached Figure 4 As shown, a first guide 15 is provided at the upper end of the base 141 . The first guide 15 is used to contact the bottom of the thermal runaway battery pack and play a guiding role, so that the thermal runaway battery pack can enter the accommodation space through the battery inlet 101 .

[0057] The first guide member 15 includes a frame 151 and a first rotating member 152. The frame 151 is arranged at an angle, and the height dimension of the frame 151 on the side close to the battery inlet 101 in the first direction is greater than the height dimension of the side away from the battery inlet 101. The height dimension of the frame 151 on the side close to the battery inlet 101 in the first direction is matched with the height dimension of the guide rail 20. The first rotating member 152 is rotatably installed on the frame 151. The first rotating member 152 is used to contact the bottom of the thermal runaway battery pack and play a guiding role.

[0058] The thermal runaway battery pack can enter the battery inlet 101 through the guide rail 20 and slide into the accommodating space from the battery inlet 101 through the first guide member 15, which is beneficial to improving the transportation efficiency of the thermal runaway battery pack. Due to the inclined setting of the frame 151, the thermal runaway battery pack can smoothly enter the accommodating space and is not easy to escape from the accommodating space.

[0059] Optionally, the frame 151 is detachably mounted on the base 141 by screwing.

[0060] Optionally, the first rotating member 152 is configured as a roller, the axial direction of which extends along the second direction, and the roller can rotate around its own axial direction.

[0061] Optionally, the first guide members 15 are provided in two groups and are symmetrically arranged on the base 141 in the second direction.

[0062] In an example scenario, as shown in the attached Figure 4 As shown, a second guide 16 is provided on the bottom bracket 141. The second guide 16 is used to contact at least one side of the thermal runaway battery pack in the second direction, and can play a guiding role to facilitate the thermal runaway battery pack to enter the accommodating space.

[0063] The second guide member 16 includes a base 161 and a second rotating member 162. The base 161 is mounted on the upper end of the base 141 and is located on the side of the first guide member 15 in the second direction away from the storage space. The second rotating member 162 is rotatably mounted on the base 161. The second rotating member 162 is designed to contact at least one side of the thermal runaway battery pack in the second direction and provide guidance. The second guide member 16 cooperates with the first guide member 15 to improve the efficiency of transporting the thermal runaway battery pack into the storage space.

[0064] Optionally, the base 161 is detachably mounted on the bottom bracket 141 by screwing.

[0065] Optionally, the second rotating member 162 is a guide wheel, the axial direction of which extends along the third direction, and the guide wheel can rotate around its own axial direction.

[0066] Optionally, the second guide members 16 are provided in two groups and are symmetrically arranged on the base 141 in the second direction.

[0067] For example, as shown in the attached Figure 6 As shown, and combined with the attached Figure 3, taking the blocking member 13 in the first position as a reference, an avoidance gap 133 is provided on a side of the blocking member 13 away from the mounting beam 103 in the first direction, and the avoidance gap 133 is opened on both sides of the blocking member 13 along the second direction, and the avoidance gap 133 penetrates the blocking member 13 along the third direction, and a sealing plate 134 is provided in the avoidance gap 133. The sealing plate 134 is movably connected to the blocking member 13 and can be flipped relative to the blocking member 13.

[0068] When installing the sealing member 13 and the support portion 14 in the main body 10, first arrange the support portion 14 in the upper cavity. At this time, the sealing member 13 is located in the second position. Then, the sealing member 13 is flipped relative to the mounting beam 103 to move the sealing member 13 to the first position. During the flipping process of the sealing member 13, the sealing plate 134 can move relative to the sealing member 13 to avoid the second guide member 16.

[0069] In one example scenario, in conjunction with the Figure 3 and attached Figure 4 The support portion 14 is detachably mounted in the upper cavity through the fixing portion 17 , and the fixing portion 17 is used to lock or unlock the support portion 14 .

[0070] For example, in conjunction with Figure 4 and attached Figure 7 The fixing part 17 includes a first driving source 171 and a limiting member 172. The first driving source 171 is used to drive the limiting member 172 to move along the first direction. When the support part 14 is in a locked state, the limiting member 172 cooperates with the support part 14 to limit the support part 14 in the third direction. When the support part 14 is in an unlocked state, the limiting member 172 moves along the first direction to separate from the support part 14 under the drive of the first driving source 171. The support part 14 loses support in the third direction and falls into the lower cavity under the action of gravity.

[0071] As attached Figure 4 As shown, the functional frame 142 is provided with a slide 1421 on one side away from the accommodation space in the second direction. Figure 5 A slide rail 104 is provided in the main body 10 to cooperate with the slide seat 1421. The slide rail 104 extends along the third direction. When the support part 14 is in the unlocked state, the slide seat 1421 slides with the slide rail 104, so that the support part 14 can fall stably in the third direction to ensure that the thermal runaway battery pack can enter the lower cavity efficiently and smoothly with the support part 14.

[0072] Optionally, two slides 1421 are provided on the functional frame 142 , and the two slides 1421 are installed on the functional frame 142 at intervals along the first direction. The support portion 14 includes a total of four slides 1421 , and the number of the slide rails 104 is set corresponding to the number of the slides 1421 .

[0073] Combined with attachment Figure 4 and attached Figure 7 The limiting member 172 includes a base 1721 and a stopper 1722. The stopper 1722 is mounted on the base 1721. Figure 8 A contact piece 1422 is protruding from the functional frame 142 on one side away from the accommodating space in the second direction. When the support portion 14 is in a locked state, the stopper 1722 is located at the lower end of the contact piece 1422 and is used to support the contact piece 1422, that is, the support portion 14 is installed in the upper cavity through the stopper 1722.

[0074] Combined with attachment Figure 7 and attached Figure 8 A guide seat 1723 is provided on the base 1721, and a guide rail 105 is provided in the main body 10. The guide rail 105 extends along the first direction, and the guide seat 1723 is slidably provided on the guide rail 105. Under the drive of the first driving source 171, the base 1721 can move along the first direction relative to the guide rail 105 through the guide seat 1723, thereby changing the position of the block 1722 relative to the contact member 1422 to achieve unlocking of the support portion 14.

[0075] For example, the first driving source 171 is an electric push rod, as shown in the attached Figure 7 As shown, the first driving source 171 is connected to the base 1721 through a driving rod 1711 .

[0076] For example, as shown in the attached Figure 7 As shown, the first driving source 171 is installed in the main body 10 through the mounting seat 1712. Optionally, the mounting seat 1712 and the main body 10 are detachably connected by screwing.

[0077] Exemplarily, the block 1722 can rotate relative to the contact member 1422. The block 1722 can adopt a guide wheel, or the block 1722 includes a bearing. Such a setting can not only support the contact member 1422, but also reduce the friction between the block 1722 and the contact member 1422, which is conducive to achieving efficient unlocking of the support part 14.

[0078] Optionally, two contact members 1422 are provided on the functional frame 142, and the two contact members 1422 are installed on the functional frame 142 at intervals along the first direction. The support portion 14 includes a total of four contact members 1422, and the number of the limiting members 172 is set corresponding to the number of the contact members 1422, as shown in the attached figure. Figure 7 As shown, two bases 1721 on the same functional frame 142 are connected by a connecting rod 1724, which enables synchronous movement of the two bases 1721. It can be understood that the fixing portion 17 is provided in two groups and is located on both sides of the supporting portion 14 in the second direction.

[0079] Optionally, the support portion 14 further includes a detection member for detecting whether a thermal runaway battery pack is contained in the accommodating space. When it is detected that a thermal runaway battery pack is contained in the accommodating space, the first driving source 171 operates to automatically unlock the support portion 14 .

[0080] In an example scenario, as shown in the attached Figure 1 As shown, the guide rail 20 also includes a second guide section 202 located outside the battery swap station. The first guide section 201 and the second guide section 202 are directly or indirectly connected, and the battery inlet 101 cooperates with the second guide section 202. The thermal runaway battery pack can be transported from the battery swap station to the main body 10 outside the battery swap station through the guide rail 20, and enter the accommodating cavity 102 through the battery inlet 101 for fire protection treatment.

[0081] For example, as shown in the attached Figure 1 As shown, the first guide segment 201 and the second guide segment 202 are both configured as linear tracks and extend along a first direction. The first guide segment 201 and the second guide segment 202 are connected along the first direction to form a linear guide track 20. This configuration can improve the transport efficiency of thermal runaway battery packs. Optionally, the first guide segment 201 and the second guide segment 202 are integrally formed.

[0082] It can be understood that the number, length and shape of the first guide segments 201 and the second guide segments 202 can be set according to actual needs.

[0083] In an example scenario, as shown in the attached Figure 9 As shown, the guide rail 20 includes a rail frame 21, a driving part 22 and a conveying part 23. The driving part 22 and the conveying part 23 are installed on the rail frame 21. The conveying part 23 is in contact with the thermal runaway battery pack for conveying the thermal runaway battery pack. The driving part 22 is used to drive the conveying part 23 to move.

[0084] For example, in conjunction with Figure 9 and attached Figure 10 The driving part 22 includes a second driving source 221, a first sprocket 222, a second sprocket 223 and a chain 224. The second driving source 221 is installed on the track frame 21. The second driving source 221 is connected to the first sprocket 222 and is used to drive the first sprocket 222 to rotate around its own axis. The first sprocket 222 and the second sprocket 223 are distributed along the first direction and are connected by the chain 224. The first sprocket 222 drives the second sprocket 223 to rotate around its own axis through the chain 224. The driving part 22 and the conveying part 23 are connected by a transmission shaft 225, and the transmission shaft 225 extends along the second direction.

[0085] In an optional solution, the second driving source 221 is a motor.

[0086] For example, in conjunction with Figure 9 and attached Figure 10 The conveying part 23 includes a conveying plate chain 231, a transmission wheel 232 and a connecting wheel 233. The transmission wheel 232 is connected to the second sprocket 223 through a transmission shaft 225. The transmission shaft 225 drives the transmission wheel 232 to rotate. The transmission wheel 232 and the connecting wheel 233 are distributed along the first direction and are connected through the conveying plate chain 231. The connecting wheel 233 is installed on the track frame 21. Through the cooperation between the transmission wheel 232 and the connecting wheel 233, the conveying plate chain 231 is driven to move, and the thermal runaway battery pack can be conveyed along the first direction.

[0087] In an optional solution, the conveying parts 23 are provided in two groups and are installed on the track frame 21 at intervals in the second direction. The transmission shaft 225 is used to connect the transmission wheels 232 of the two groups of conveying parts 23 .

[0088] For example, as shown in the attached Figure 9 As shown, the guide rail 20 also includes a side stop 24, which is located on the side where the two groups of conveying parts 23 are away from each other in the second direction. The side stop 24 is used to limit the thermal runaway battery pack in the second direction to prevent the thermal runaway battery pack from shifting in position or falling off from the conveying part 23 during transportation, thereby ensuring transportation efficiency.

[0089] In an optional embodiment, the side stop 24 includes a bracket 241 and a rotating wheel 242. The bracket 241 is mounted on the track frame 21. The rotating wheel 242 can rotate about its own axis relative to the bracket 241, and the axial direction of the rotating wheel 242 extends along the third direction. The rotating wheel 242 is configured to contact both sides of the thermal runaway battery pack in the second direction. The rotating wheel 242 cooperates with the conveying portion 23 to guide the thermal runaway battery pack and ensure smooth conveying. Optionally, the bracket 241 is detachably connected to the track frame 21 by screwing.

[0090] Exemplarily, the track frame 21 includes two sets of first frames extending along the second direction, and a second frame for connecting the two sets of first frames. The first frame is used to install the conveying part 23 and the side block part 24, and the second frame is used to increase the structural stability of the first frame.

[0091] By setting the above-mentioned guide rail 20, the automatic transportation of the thermal runaway battery can be achieved, which saves manpower and improves the operational safety during the transportation and transfer of the thermal runaway battery.

[0092] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
