Description

Technical Field

[0001] The present invention relates to the technical field of energy storage devices, and in particular to a highly safe partition-type energy storage device. Background Art

[0002] Electrochemical energy storage utilizes chemical reactions to achieve energy conversion and storage. For example, the charging and discharging of batteries utilizes electrochemical reactions to convert electrical energy into chemical energy for storage, and then converts the chemical energy back into electrical energy for release. To increase the storage capacity of energy storage devices, battery packs are typically used. To power two or more power supply devices, two or more battery packs are typically operated simultaneously. Each battery pack includes at least one output connector and one input connector to enable both power output and input.

[0003] In the prior art, when two or more battery packs are used, they are all placed in the same cavity for ease of maintenance and unified heat dissipation. However, this has more obvious disadvantages, because two or more battery packs are placed in the same cavity, and the battery packs will generate high temperatures during operation, and even fire. If a battery in one battery pack catches fire, it is very likely to cause multiple battery packs in the same cavity to be affected. To improve the safety of use, the prior art also has a design that separates the individual battery packs.

[0004] In the prior art similar to the field of this application, such as the invention patent with application number 202411575516.9 and publication (announcement) number CN119092922B, a partitioned energy storage power station and its power supply grid connection method are disclosed. The battery cavity of the energy storage power station is separated by a partition plate to install the battery pack in each independent cavity, so that when a fire occurs in a single battery pack, it can be separated in time to prevent the spread of fire; and when a fire occurs, the heat dissipation slots on the upper and lower sides of the partition plate are blocked by a lifting plate, and the installation slot can be opened by a fire curtain. The fire curtain is closed and the plug is easily detached from the adapter plug. At the same time, the docking block pulls the fire curtain to isolate the flame when it moves along the base, and the push wheel on it rotates, which generates an outward thrust when it contacts the plug, causing the plug to detach from the adapter socket, and promptly disconnecting the battery packs in different cavities or the electrical equipment of the energy storage power station, ensuring that the fire curtain can cover the installation slot and prevent the spread of flames.

[0005] Although the above-mentioned invention patent can isolate the battery pack and, in the event of a fire, can generate power by driving the gas in the expansion box to expand due to high temperature to retract the clamping member and rotate the push wheel, and the push wheel generates an outward thrust when it contacts the plug, causing the plug to detach from the adapter socket, thereby providing safer protection, its disadvantages are also obvious: First, to prevent the spread of fire, the above-mentioned prior art only uses a fire curtain to block the heat dissipation slots and installation slots on the partition plate, thereby isolating two adjacent battery packs. However, the battery pack on fire is completely unobstructed between the inner cavity where it is located. As a result, the battery pack flames can contact the inner wall of the cavity where it is located, which can easily damage the inner wall of the power station body. In order to achieve a stable connection between the connector and the socket, the above-mentioned prior art additionally adds a structural setting of a clamping part, and in order to disengage the connector and the socket, a series of transmission structures are added. The expansion of the gas in the expansion gas box drives the series of transmission structures to achieve the disengagement of the connector and the socket. That is, in order to achieve a certain specific function (such as the stable connection function between the connector and the socket and the separation function of the connector and the socket), a specific structure is added, which makes the utilization rate of the structure low and makes the structure relatively complex.

[0006] In summary, how to achieve isolation of adjacent battery packs while separating the battery pack from the inner cavity in which it is located to prevent the battery pack flame from contacting the inner wall of the cavity in which it is located, thereby preventing damage to the inner wall of the power station body, and how to improve the structural utilization rate to simplify the structure while ensuring the firm connection between the connector and the socket and the automatic separation of the connector and the socket is required is a technical problem that needs to be solved urgently. Summary of the Invention

[0007] The object of the present invention is to provide a highly safe isolated energy storage device to address the above-mentioned deficiencies in the prior art.

[0008] To achieve the above objectives, the present invention provides the following technical solutions: a highly safe partitioned energy storage device comprising a main body and a fire wall fixedly disposed within the main body, wherein support platforms for placing battery packs are fixedly mounted on both left and right sides of the fire wall, the fire wall being provided with sockets for inserting connectors on the battery packs, and fire covers that can be expanded and folded in a fan-shaped manner on both left and right sides of the fire wall via a roller, one side of the fire cover being sealed and fixedly connected to a side of the fire wall, and the other side being fixedly mounted with a swinging U-shaped frame, the swinging U-shaped frame being fixedly connected to the roller, and the roller being elastically rotatably connected to the fire wall; A rope is connected between the swinging U-shaped frame and the joint, a reversing member corresponding to the joint is elastically rotatably connected to the firewall, a locking plate is slidably provided on the firewall to abut against the reversing member, and when the second directional wheel is folded, the reversing member is locked by the locking plate so that the rope abuts against the reversing member and then passes through the reversing member and tightens the joint toward the firewall; A heated cylinder corresponding to the lock plate is fixedly installed on the fire wall. When the temperature rises, the piston rod on the heated cylinder pushes the lock plate to separate from the reversing member to unlock the reversing member, so that on the one hand, the reversing member rotates elastically to allow the rope to abut and bypass the reversing member and then pull the connector away from the fire wall until the connector is separated from the socket. On the other hand, the swing U-shaped frame rotates elastically to pull the fireproof cover to unfold and cover the battery pack.

[0009] In the above-mentioned partition-type energy storage device with high safety, a mounting frame corresponding to the reversing member is fixedly mounted on the firewall, and the reversing member is elastically rotatably mounted on the mounting frame.

[0010] The above-mentioned high-safety partition-type energy storage device, the reversing member includes an L-shaped reversing plate corresponding to the joint, one end of the L-shaped reversing plate is fixedly mounted with a rotating shaft elastically rotatably connected to the mounting frame, a third directional wheel is rotatably mounted on the rotating shaft, one of the joints is configured with two L-shaped reversing plates, the joint is located between the two L-shaped reversing plates, and the L-shaped reversing plates are sequentially provided with a first directional wheel and a second directional wheel.

[0011] The above-mentioned high-safety partition-type energy storage device has an auxiliary rod corresponding to the rope fixedly installed on the joint, and a pressure rod fixedly bonded to the first directional wheel. When the fireproof cover is folded, one end of the rope is fixedly connected to the auxiliary rod, and the other end passes between the pressure rod and the first directional wheel, then abuts and bypasses the second directional wheel and is fixedly connected to the swinging U-shaped frame. During the deployment of the fireproof cover, as the reversing member elastically rotates, the pressure rod applies pressure to the rope to drive the rope to always be in a tensioned state so that the rope abuts against the third directional wheel, thereby changing the tension of the rope on the joint from toward the firewall to away from the firewall.

[0012] In the above-mentioned highly safe partition-type energy storage device, during the deployment of the fireproof cover, when the joint is pulled by the rope and separated from the socket, the swinging U-shaped frame continues to rotate elastically to drive the rope to pull the auxiliary rod to hit the pressure rod to separate the pressure rod from the first directional wheel.

[0013] The above-mentioned high-safety partition-type energy storage device, the L-shaped reversing plate includes an L-shaped abutment plate fixedly arranged at its bottom, and the lock plate includes a locking block fixedly arranged on its side and abutting against the L-shaped abutment plate. When the lock plate slides, the locking block is driven to stagger with the L-shaped abutment plate to unlock the L-shaped reversing plate.

[0014] The above-mentioned high-safety partition-type energy storage device has a sliding rail corresponding to one end of the lock plate and a cylinder corresponding to the other end of the lock plate fixedly installed on the firewall. One end of the lock plate is fixedly provided with a sliding plate that is slidably plugged into the sliding rail, and the other end is formed with a long hole, and the cylinder slides through the long hole.

[0015] The above-mentioned high-safety partition-type energy storage device has a lock hole corresponding to the lock plate on the roller. After the locking block and the L-shaped abutment plate are staggered, the sliding plate and the slide rail are staggered so that the lock plate rotates around the cylinder toward the roller. When the fireproof cover is unfolded and covers the battery pack, the lock hole is rotated to the bottom of the lock plate so that the end of the lock plate is obliquely inserted into the lock hole to lock the fireproof cover.

[0016] The above-mentioned high-safety partition-type energy storage device has a fixed U-shaped frame fixedly installed on the side of the fireproof cover away from the swinging U-shaped frame, which is sealed and fixedly connected to the side of the fire wall. Both ends of the fixed U-shaped frame are equipped with a first ring body, which is rotatably sleeved on the roller.

[0017] The above-mentioned high-safety partition-type energy storage device, the mounting frame includes a second bracket fixedly connected to the firewall and a first bracket fixedly connected to the second bracket, the second bracket and the first bracket are both rotatably connected to an L-shaped reversing plate, and an avoidance gap is formed between the first bracket and the firewall so that the mounting frame will not block the lock plate from rotating toward the roller.

[0018] Beneficial effects: 1. In the above technical solution, the present invention provides a highly secure partitioned energy storage device. When a fire occurs in the battery pack, the device automatically changes direction by unlocking the reversing member, causing the fireproof cover to fan out and cover the battery pack, separating the battery pack from the inner wall of the cavity in which it is located. The flame is blocked by the fireproof cover and will not come into contact with the inner wall of the main body, making it less likely to cause damage to the inner wall of the main body. Moreover, the same structure is used to achieve a secure connection between the connector and the socket, as well as the automatic separation of the connector and the socket. The direction of the rope tension is changed by cleverly utilizing the different states of the reversing member, eliminating the need for a clamping member to separately secure the connector in the prior art. This makes the structure more versatile, improves the utilization rate of the structure, simplifies the structure, and effectively addresses the shortcomings of the prior art. 2. In the present invention, one end of the lock plate is slidably connected to the slide rail, and the other end is slidably plugged into the cylinder through an elongated hole, and a lock hole is provided on the roller. When the lock plate is pushed and slid by the piston rod on the heated cylinder, the lock plate can be separated from the slide rail, so that the lock plate can be rotated and inserted into the lock hole, so that the lock plate can cleverly lock the roller and the fireproof cover. Even if the battery pack is subjected to a large impact force, the fireproof cover will not be opened. The cooperation between the lock plate and the roller produces an unexpected technical effect, and the fireproof cover can be locked without configuring a locking mechanism.

DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-19 As shown, an embodiment of the present invention provides a highly safe partitioned energy storage device, comprising a main body 1 and a firewall 3 fixedly arranged in the main body 1, wherein support platforms 4 for placing a battery pack 24 are fixedly installed on both sides of the firewall 3, and a socket for inserting a connector 15 on the battery pack 24 is provided on the firewall 3. A fan-shaped and foldable fireproof cover 2 is provided on both sides of the firewall 3 through a roller 5, and one side of the fireproof cover 2 is sealed and fixedly connected to the side of the firewall 3, and a swing U-shaped frame 17 is fixedly installed on the other side, and the swing U-shaped frame 17 is fixedly connected to the roller 5, and the roller 5 is elastically rotatably connected to the firewall 3; A rope 14 is connected between the swing U-shaped frame 17 and the joint 15. The rope 14 is made of a fire-resistant material such as steel wire or iron wire. A reversing member corresponding to the joint 15 is elastically and rotatably connected to the fire wall 3. A locking plate 8 is slidably provided on the fire wall 3 to abut against the reversing member. When the second directional wheel 12 is folded, the reversing member is locked by the locking plate 8, so that the rope 14 abuts against the reversing member and then passes through the reversing member, and then tightens the joint 15 toward the fire wall 3. A heated cylinder 18 corresponding to the locking plate 8 is fixedly mounted on the fire wall 3. When the temperature rises, the piston rod 1801 on the heated cylinder 18 pushes the locking plate 8 to separate from the reversing member to unlock the reversing member, so that on the one hand, the reversing member rotates elastically to allow the rope 14 to abut against and bypass the reversing member and then pull the connector 15 away from the fire wall 3 until the connector 15 is separated from the socket; on the other hand, the swing U-shaped frame 17 rotates elastically to pull the fireproof cover 2 to unfold and cover the battery pack 24. The fireproof cover 2 is made of refractory fiber with folding folds, which has certain elasticity and softness. Its material is prior art and will not be described in detail.

[0024] The highly secure, isolated energy storage device provided in this embodiment is used to charge electrical equipment. Terms related to direction and position are relative to the accompanying drawings. Specifically, a main body 1 comprises a cavity with a door opening for passage of equipment components and workers. A blocking door (not shown) is installed in the door opening, which blocks the door opening during normal operation. A ventilator 23 is fixedly mounted on the main body 1 to exhaust gas from the internal cavity of the main body 1. Ventilator 23 is conventional and will not be described in detail in this embodiment. A fire wall 3 is fixedly mounted within the internal cavity of the main body 1. The front and rear sides, as well as the upper and lower sides, of the fire wall 3 are sealed and fixedly connected to the inner wall of the main body 1, so that the fire wall 3 divides the internal cavity of the main body 1 into multiple completely independent cavities. Each independent cavity houses a battery pack 24. If additional battery packs 24 are needed, the number of fire walls 3 can be increased as needed. Each additional fire wall 3 increases the number of independent cavities within the main body 1 by one, each housing a battery pack 24. The support platform 4 is fixedly connected to the fire wall 3, and the bottom of the support platform 4 is suspended in the air. When the fireproof cover 2 covers the battery pack 24, the support platform 4 is also covered together. Each battery pack 24 includes at least two connectors 15, one is an input connector and the other is an output connector. The input connector and the output connector are both connected to the battery pack 24 through wires 25. The firewall 3 is provided with an input socket 303 for plugging in the input connector and an output socket 304 for plugging in the output connector. The firewall 3 is also provided with an input external interface 301 and an output external interface 302. The interior of the firewall 3 is provided with a first cable channel and a second cable channel. The input external interface 301 is connected to the input socket 303 through the first cable channel, and the output external interface 302 is connected to the output socket 304 through the second cable channel. A first cable is connected between the input external interface 301 and the input socket 303, and the first cable passes through the first cable channel. A second cable is connected between the output external interface 302 and the output socket 304, and the second cable passes through the second cable channel. An opening 101 is provided on the main body 1 to expose the input external interface 301 and the output external interface 302, so as to facilitate the plugging and use of external charging equipment and electrical equipment. The two connectors 15 are plugged into the input socket 303 and the output socket 304 in a one-to-one correspondence. The input socket 303 and the output socket 304 are located at the same height, so that the two connectors 15 have the same height. Each connector 15 is equipped with a diverter. Since the two connectors 15 are at the same height, the two diverters are also at the same height. The ropes 14 on the two diverters are fixedly connected to the swinging U-shaped frame 17. When the fireproof cover 2 is deployed, the two diverters rotate synchronously, so that the two connectors 15 are separated from the sockets synchronously or substantially synchronously, thereby enabling the swinging U-shaped frame 17 to rotate smoothly to deploy the fireproof cover 2.

[0025] The heated cylinder 18 is fixedly mounted on the side of the firewall 3. A piston rod 1801 is sealed and slidably inserted at one end of the heated cylinder 18, which abuts the end face of the lock plate 8. The inner cavity of the heated cylinder 18 is filled with a gas that expands when heated, such as hydrogen, helium, nitrogen, or oxygen. When a fire occurs, the temperature of the inner cavity of the main body 1 rises, causing the gas in the inner cavity of the heated cylinder 18 to expand, driving the piston rod 1801 to slide toward the outside of the heated cylinder 18, so that the piston rod 1801 pushes the corresponding lock plate 8 to slide. A reversing member is configured with one lock plate 8 and one heated cylinder 18. The two heated cylinders 18 are symmetrically arranged, and the two lock plates 8 are also symmetrically arranged. The two lock plates 8 are located between the two heated cylinders 18, and the piston rod 1801 on the heated cylinder 18 abuts the end face of the corresponding lock plate 8.

[0026] In this embodiment, the fireproof cover 2 can be fan-shaped and folded. Under normal working conditions, the fireproof cover 2 is always in the folded state. At this time, the reversing member is locked by the lock plate 8. Under the action of the reversing member, the rope 14 generates a pulling force on the joint 15 toward the firewall 3 to tighten and fix the joint 15 to prevent the joint 15 from separating from the socket. The pulling force of the rope 14 on the joint 15 comes from the elastic rotation force of the swing U-shaped frame 17. The direction of the elastic rotation force of the swing U-shaped frame 17 is the direction of the fireproof cover 2 to be expanded. The direction of the elastic rotation of the reversing member is also the direction of the fireproof cover 2 to be expanded. When the reversing member is locked by the lock plate 8, It cannot rotate in the direction of deployment of the fireproof cover 2; when a fire occurs, the piston rod 1801 on the heated cylinder 18 drives the lock plate 8 to slide to separate the lock plate 8 from the corresponding reversing member, thereby unlocking the reversing member, so that the reversing member elastically rotates in the direction of deployment of the fireproof cover 2, so that the reversing member changes the direction of the pulling force generated by the rope 14 on the joint 15, and the direction of the pulling force changes from toward the firewall 3 to away from the firewall 3, thereby pulling the joint 15 apart from the socket. At this time, the pulling force of the rope 14 on the joint 15 is provided by the elastic rotation force of the reversing member and the elastic rotation force of the swinging U-shaped frame 17. At the same time, since the reversing member elastically rotates in the direction of the fire hood 2 after being unlocked, the swinging U-shaped frame 17 also elastically rotates in the direction of the fire hood 2, so that the swinging U-shaped frame 17 rotates to abut against the side of the firewall 3. The elastic rotation of the swinging U-shaped frame 17 pulls the fire hood 2 to expand in a fan shape, so that the fire hood 2 covers the corresponding battery pack 24, thereby separating the battery pack 24 from the inner wall of the cavity in which it is located. When the battery pack 24 catches fire, the flame is blocked by the fire hood 2 and will not contact the inner wall of the main body 1, thereby not easily causing damage to the inner wall of the main body 1. Moreover, the firm connection between the connector 15 and the socket and the automatic separation between the connector 15 and the socket are both achieved by the tension provided by the rope 14 under the interaction between the swinging U-shaped frame 17, the reversing member, and the locking plate 8. It is just that the different states of the reversing member are cleverly utilized to change the direction of the tension of the rope 14 on the connector 15, making the structure more versatile and improving the utilization rate of the structure, thereby simplifying the structure.

[0027] Thus, it can be seen that in the present application, when a fire occurs in the battery pack 24, the direction is automatically changed by unlocking the reversing member, so that the fireproof cover 2 fan-shapedly expands to cover the battery pack 24, separating the battery pack 24 from the inner wall of the cavity in which it is located. The flame is blocked by the fireproof cover 2 and will not come into contact with the inner wall of the main body 1, thereby less likely to cause damage to the inner wall of the main body 1. Moreover, the secure connection between the connector 15 and the socket and the automatic separation of the connector 15 and the socket are both achieved by relying on the same structure. It is only by cleverly utilizing the automatic state switching of the reversing member to change the pulling direction of the rope 14, eliminating the provision of a clamping member for separately fixing the connector 15 in the prior art, making the structure more versatile, improving the utilization rate of the structure, and simplifying the structure, which can effectively address the shortcomings of the prior art.

[0028] The left and right sides of the firewall 3 are provided with inner grooves, and two seats 6 are fixedly installed in the inner grooves along the length direction of the inner grooves. The two ends of the roller 5 are rotatably plugged into the two seats 6 in a one-to-one correspondence, and a bearing 603 is installed between the end of the roller 5 and the seat 6 to reduce the friction between the seat 6 and the roller 5. There are many ways to elastically rotate the roller 5 and the firewall 3. For example, a first fixed block 601 is fixedly installed on the seat 6, and a first guide ring 602 coaxial with the roller 5 is fixedly installed on the first fixed block 601. A first swing plate 501 is fixedly installed on the end of the roller 5, and a first arc-shaped compression spring 21 is sleeved on the first guide ring 602. One end of the first arc-shaped compression spring 21 elastically contacts the first swing plate 501. The first end of the roller 5 is connected to the first fixed block 601, and the other end is elastically abutted against the first fixed block 601. The first arc-shaped compression spring 21 applies a thrust to the first swinging plate 501 in the direction of unfolding the fireproof cover 2, thereby realizing elastic rotation between the roller 5 and the fire wall 3. When the reversing member is unlocked, the elastic force of the first arc-shaped compression spring 21 is released, and pushes the first swinging plate 501 and the roller 5 to rotate in the direction of unfolding the fireproof cover 2. The roller 5 then drives the swinging U-shaped frame 17 to rotate to unfold the fireproof cover 2 until the swinging U-shaped frame 17 is in contact with the side of the fireproof cover 3, so that the fireproof cover 2 covers the battery pack 24. For example, a torsion spring is fixedly installed on the roller 5, and the free end of the torsion spring is elastically abutted against the first fixed block 601. The elastic rotation between the roller 5 and the fireproof cover 3 is realized based on the torsion of the torsion spring.

[0029] In this embodiment, a ventilator 23 is installed on the main body 1 for dissipating heat from the inner cavity of the main body 1. The structure of the ventilator 23 is prior art and will not be described in detail. A ventilation hole 305 is provided on the firewall 3 for connecting the cavities on the left and right sides of the firewall 3, so that the temperatures of the cavities on the left and right sides of the firewall 3 are the same or similar. When the fireproof cover 2 covers the battery pack 24, since the battery pack 24 is separated from the cavity in which it is located, the fireproof cover 2 does not need to cover the ventilation hole 305, and the ventilation hole 305 does not need to be blocked intentionally, and will not affect the battery pack 24 in the adjacent cavity.

[0030] In this embodiment, a mounting bracket corresponding to the reversing member is fixedly mounted on the firewall 3, and the reversing member is elastically rotatably mounted on the mounting bracket. The connection position between the mounting bracket and the reversing member extends away from the firewall 3 so that the reversing member has sufficient rotation space.

[0031] The reversing member includes an L-shaped reversing plate 7 corresponding to the joint 15, and one end of the L-shaped reversing plate 7 is fixedly mounted with a rotating shaft 702 elastically rotatably connected to the mounting frame, and a third directional wheel 13 is rotatably mounted on the rotating shaft 702. A reversing member includes two L-shaped reversing plates 7, that is, one joint 15 is configured with two L-shaped reversing plates 7, and the joint 15 is located between the two L-shaped reversing plates 7. The first directional wheel 11 and the second directional wheel 12 are sequentially arranged on the L-shaped reversing plate 7. Specifically, a second fixed block 901 is fixedly installed on the mounting frame, a second guide ring 902 coaxial with the rotating shaft 702 is fixedly installed on the second fixed block 901, a second swinging plate 7021 is fixedly installed on the rotating shaft 702, and a second arc-shaped compression spring 22 is sleeved on the second guide ring 902, one end of the second arc-shaped compression spring 22 elastically abuts against the second fixed block 901, and the other end elastically abuts against the second swinging plate 7021, the second arc-shaped compression spring 22 is similar to the left and right of the first arc-shaped compression spring 21, the second arc-shaped compression spring 22 and the first arc-shaped compression spring 21 are always in a compressed state, the elastic direction of the second arc-shaped compression spring 22 on the second swinging plate 7021 is the direction in which the fireproof cover 2 is deployed, based on the elasticity of the second arc-shaped compression spring 22 The force causes the L-shaped reversing plate 7 to abut stably against the locking plate 8, preventing the L-shaped reversing plate 7 from shaking when locked. When the locking plate 8 releases the lock on the L-shaped reversing plate 7, the elastic force of the second arc-shaped compression spring 22 is released, pushing the second swing plate 7021 and the rotating shaft 702 to rotate in the direction of deployment of the fireproof cover 2. The rotating shaft 702 then drives the L-shaped reversing plate 7 to rotate around the axis of the rotating shaft 702. The L-shaped reversing plate 7 drives the first and second directional wheels 11 and 12 to rotate synchronously around the axis of the rotating shaft 702, causing the first and second directional wheels 11 and 12 to rotate from one side of the rotating shaft 702 to the opposite side of the rotating shaft 702, thus achieving elastic rotation of the reversing member and thereby changing the direction of the pulling force of the rope 14 on the joint 15. The first and second directional wheels 11 and 12 are both rotatably connected to the L-shaped reversing plate 7 to reduce the friction force on the rope 14.

[0032] For further reference, Figure 8An auxiliary rod 1501 corresponding to the rope 14 is fixedly installed on the joint 15, and a pressure rod 1101 is fixedly bonded to the first directional wheel 11. When the fireproof cover 2 is folded, one end of the rope 14 is fixedly connected to the auxiliary rod 1501, and the other end passes between the pressure rod 1101 and the first directional wheel 11, then abuts and bypasses the second directional wheel 12, and is fixedly connected to the swing U-shaped frame 17. During the deployment of the fireproof cover 2, as the reversing member elastically rotates, the pressure rod 1101 applies pressure to the rope 14 to drive the rope 14 to always be in a tensioned state so that the rope 14 abuts against the third directional wheel 13, thereby changing the pulling force of the rope 14 on the joint 15 from toward the firewall 3 to away from the firewall 3. Specifically, two auxiliary rods 1501 and two L-shaped reversing plates 7 are configured on a joint 15, corresponding to each other. A rope 14 is connected between each auxiliary rod 1501 and each L-shaped reversing plate 7. By configuring two ropes 14 on a joint 15 to provide it with tension, the force balance of the joint 15 can be improved, thereby increasing the stability of the joint 15 when connected to the socket and reducing the difficulty of pulling the joint 15 out of the socket, and each rope 14 is configured with a first directional wheel 11, a second directional wheel 12, and a third directional wheel 13. Furthermore, when the reversing member is unlocked, the swinging U-shaped frame 17 and the reversing member both rotate elastically in the direction of unfolding the fireproof cover 2. In order to prevent the originally tensioned rope 14 from becoming loose during the rotation, which causes the rope 14 to be unable to be accurately transferred to the corresponding third directional wheel 13, in this embodiment, a pressure rod 1101 is fixed and bonded to the first directional wheel 11. When the reversing member is locked, the pressure rod 1101 is located directly below the first directional wheel 11, and the pressure rod 1101 is bonded to the outer peripheral surface of the first directional wheel 11. When the reversing member is unlocked and rotates elastically, the pressure rod 1101 abuts against the corresponding rope 14 and pulls the rope 14 so that the rope 14 is always in a tensioned state, thereby facilitating the accurate delivery of the rope 14 to the corresponding third directional wheel 13.

[0033] Among them, the rope 14 is connected to the auxiliary rod 1501 through a rotating ring. An annular groove is provided on the auxiliary rod 1501. The axial length of the annular groove is within 1 mm longer than the axial length of the rotating ring. The rotating ring is rotatably sleeved on the annular groove so that the rotating ring can rotate while not easily moving in the axial direction. The center position of the outer peripheral surface of the auxiliary rod 1501 is fixedly connected to the rope 14. When the reversing member rotates, the rotating ring also rotates around the auxiliary rod 1501 as the pulling direction of the rope 14 changes.

[0034] In this embodiment, the bonding force between the pressure bar 1101 and the first directional wheel 11 is greater than the force used to pull the connector 15 out of the socket, so that when the connector 15 is separated from the socket, the first directional wheel 11 does not separate from the pressure bar 1101. During the deployment of the fireproof cover 2, after the connector 15 is pulled by the rope 14 and separated from the socket, the swinging U-shaped frame 17 continues to elastically rotate, driving the rope 14 to pull the auxiliary rod 1501 to hit the pressure bar 1101, so that the pressure bar 1101 is separated from the first directional wheel 11. The force of the swinging U-shaped frame 17 pulling the auxiliary rod 1501 to hit the pressure bar 1101 through the rope 14 is greater than the bonding force between the first directional wheel 11 and the pressure bar 1101, so that the pressure bar 1101 can be knocked off by the auxiliary rod 1501. However, whether the auxiliary rod 1501 hits the pressure bar 1101 depends on the position of the swinging U-shaped frame 17 and the length of 14. When the swinging U-shaped frame 17 is in contact with the firewall 3 and the length of 14 is long enough, the auxiliary rod 1501 will not hit the pressure bar 1101. At this time, the pressure bar 1101 does not need to be separated from the first directional wheel 11.

[0035] When the lock plate 8 slides, the two locking blocks 801 are driven to stagger with the two L-shaped abutment plates 701 to unlock the L-shaped reversing plate 7.

[0036] A plurality of balls 7011 are fixedly embedded or rollingly embedded on the L-shaped abutment plate 701, and the tops of the plurality of balls 7011 protrude from the L-shaped abutment plate 701 and abut against the locking block 801 to reduce the friction between the locking block 801 and the L-shaped abutment plate 701 when the locking plate 8 slides.

[0037] The firewall 3 is fixedly provided with a slide rail 19 corresponding to one end of the lock plate 8 and a cylinder 20 corresponding to the other end of the lock plate 8. One end of the lock plate 8 is fixedly provided with a slide plate 803 that slides and plugs into the slide rail 19, and the other end is formed with a long hole 802, and the cylinder 20 slides through the long hole 802. Specifically, the lock plate 8 is provided with two symmetrically arranged sliding plates 803, and the two sliding plates 803 are located one by one above and below the lock plate 8. The sliding plates 803 are located at one end of the lock plate 8 close to the heated cylinder 18. A sliding groove for the two sliding plates 803 to slide into is provided on the slide rail 19. The cylinder 20 slides through the elongated hole 802. The length direction of the elongated hole 802 is consistent with the length direction of the lock plate 8. The length of the elongated hole 802 is greater than the diameter of the cylinder 20, so that the cylinder 20 can slide relative to the elongated hole 802 in the length direction of the lock plate 8. Therefore, when the piston rod 1801 is pushed out by the gas colliding in the heated cylinder 18, the piston rod 1801 can push the corresponding lock plate 8 to slide. During the sliding process of the lock plate 8, the L-shaped abutment plate 701 is first staggered with the locking block 801, and then the sliding plate 803 is staggered with the slide rail 19. A limit cap 2001 is fixedly mounted on the end surface of the cylinder 20. The front side of the lock plate 8 slides against the limit cap 2001, and the rear side slides against the firewall 3, so that the lock plate 8 is limited between the limit cap 2001 and the firewall 3. The support of the slide rail 19 on one end of the lock plate 8 and the support of the cylinder 20 on the other end of the lock plate 8 ensure that the lock plate 8 is stably horizontal. When the reversing member is locked by the lock plate 8, the lock plate 8 is in a horizontal position.

[0038] Furthermore, a lock hole 502 corresponding to the lock plate 8 is opened on the roller 5. After the locking block 801 is staggered with the L-shaped abutment plate 701, the sliding plate 803 is staggered with the slide rail 19 so that the lock plate 8 rotates around the cylinder 20 toward the roller 5. When the fireproof cover 2 is unfolded and covers the battery pack 24, the lock hole 502 is rotated to the bottom of the lock plate 8 so that the end of the lock plate 8 is obliquely inserted into the lock hole 502 to lock the fireproof cover 2. Specifically, the number of locking holes 502 is the same as that of the locking plate 8 and corresponds one to one. Based on the sliding connection between the elongated hole 802 and the cylinder 20, under the action of the gravity of the locking plate 8, when the sliding plate 803 is disengaged from the sliding rail 19, the end of the locking plate 8 close to the heated cylinder 18 rotates toward the roller 5, and when the swinging U-shaped frame 17 rotates to fit and abut against the fire wall 3, the locking hole 502 is located directly below the locking plate 8, so that when the locking plate 8 rotates, the end of the locking plate 8 is inserted into the corresponding locking hole 502, and the rotation direction of the locking plate 8 is not in the same plane as the rotation direction of the roller 5, so that when the locking plate 8 is inserted into the locking hole 502, the roller 5 is locked. After the roller 5 is locked, the swinging U-shaped frame 17 is locked, and then the fireproof cover 2 is locked. Even if the battery pack 24 is subjected to a large impact force, the fireproof cover 2 will not be opened.

[0039] It can be seen that in the present invention, one end of the lock plate 8 is slidably connected to the slide rail 19, and the other end is slidably plugged into the cylinder 20 using the elongated hole 802, and a lock hole 502 is opened on the roller 5, so that the lock plate 8 can be separated from the slide rail 19 during the process of being pushed and slid by the piston rod 1801 on the heated cylinder 18, so that the lock plate 8 is rotated and inserted into the lock hole 502, so that the lock plate 8 cleverly achieves the locking of the roller 5 and the fireproof cover 2. Even if the battery pack 24 is subjected to a large impact force, the fireproof cover 2 will not be pushed open, so that the cooperation between the lock plate 8 and the roller 5 produces an unexpected technical effect, and the fireproof cover 2 can be locked without configuring a locking mechanism.

[0040] Furthermore, a steel wire rope (not shown in the figure) is connected to one end of the lock plate 8 close to the heated cylinder 18. The steel wire rope slides through the firewall 3 and extends to the outside of the fireproof cover 2. When the lock plate 8 rotates, the rotational force of the lock plate 8 pulls the steel wire rope to slide so that the steel wire rope does not affect the rotation of the lock plate 8. When the end of the lock plate 8 is inserted into the corresponding lock hole 502, based on the length design of the steel wire rope, the end of the steel wire rope is still located outside the fireproof cover 2. When it is necessary to release the lock of the lock plate 8 on the roller 5, the lock plate 8 is rotated by pulling the steel wire rope to move the end of the lock plate 8 out of the lock hole 502.

[0041] In this embodiment, a fixed U-shaped frame 16 is fixedly mounted on the side of the fireproof cover 2 away from the swinging U-shaped frame 17 and is sealed and fixedly connected to the side of the fire wall 3. A first ring body 1601 is mounted on both ends of the fixed U-shaped frame 16, and the first ring body 1601 is rotatably mounted on the roller 5. A second ring body 1701 is fixedly mounted on both ends of the swinging U-shaped frame 17, and the second ring body 1701 is fixedly mounted on the roller 5. The swinging U-shaped frame 17 is located at the upstream end in the direction of deployment of the fireproof cover 2, and the fixed U-shaped frame 16 is located at the downstream end in the direction of deployment of the fireproof cover 2. When the fireproof cover 2 is deployed, the swinging U-shaped frame 17 rotates while the fixed U-shaped frame 16 remains stationary. The number of U-shaped frames can be increased between the swinging U-shaped frame 17 and the fixed U-shaped frame 16 as needed, and both ends of the increased U-shaped frames are rotatably connected to the roller 5. The length of the swinging U-shaped frame 17 in the axial direction of the roller 5 is less than the length of the fixed U-shaped frame 16. When the U-shaped frame is added, the length of the added U-shaped frame along the axial direction of the roller 5 in the direction in which the fire cover 2 is unfolded is reduced successively, so that both ends of the U-shaped frame can be connected to the roller 5.

[0042] The mounting frame includes a second bracket 10 fixedly connected to the firewall 3 and a first bracket 9 fixedly connected to the second bracket 10. An L-shaped reversing plate 7 is rotatably connected to the second bracket 10 and the first bracket 9. An avoidance gap is formed between the first bracket 9 and the firewall 3 so that the mounting frame will not block the lock plate 8 from rotating toward the roller 5. When the lock plate 8 rotates, it passes through the gap between the first bracket 9 and the firewall 3.

[0043] The battery pack 24 is staggered with the reversing member. Sealing plates (not shown) can be fixedly mounted on the front and rear ends of the inner grooves on the left and right sides of the fire wall 3 to fit snugly against the fire cover when the fire cover covers the battery pack, thereby ensuring a tighter seal between the fire cover and the fire wall 3.

[0044] Each U-shaped frame, such as the swing U-shaped frame 17 and the fixed U-shaped frame 16 , is installed on the inner side of the fireproof cover 14 .

[0045] In this embodiment, separating the connector 15 from the socket provides greater safety in the event of a fire in the battery pack 24, preventing flames from igniting the cables within the firewall 3 and reaching external charging devices and adjacent battery packs 24. Of course, the number of connectors 15 can also be increased in this embodiment. These additional connectors 15 are conversion connectors as described in existing patents. When these conversion connectors are added, the firewall 3 correspondingly adds the same number of sockets. The height of the additional sockets is the same as that of the input socket 303 and output socket 304 in this embodiment. The principles for reinforcing and separating the conversion connectors from the sockets are the same as those for reinforcing and separating the connectors 15 from the input socket 303 and output socket 304 in this embodiment, and are not further described.

[0046] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
