Description

Technical Field

[0001] This invention relates to the field of automotive battery storage technology, specifically to a battery storage device based on the production of new energy vehicles. Background Technology

[0002] Battery storage devices for new energy vehicle production are specialized warehousing equipment used for the temporary storage of power batteries after they come off the production line. They are mainly used for the centralized storage and management of batteries awaiting assembly on the production line. This type of equipment achieves the partitioning of multiple battery groups by dividing them into independent storage chambers, and relies on the cabinet ventilation structure to uniformly regulate the internal storage environment, ensuring that the temperature and humidity of each battery are relatively consistent. However, the aforementioned existing storage devices still have the following technical problems in practical applications.

[0003] The storage chambers are interconnected by a ventilation system. When a battery experiences thermal runaway due to internal short circuits, residual overcharge, or other reasons, the high-temperature fumes and harmful substances generated by that battery will rapidly spread to adjacent chambers through the ventilation path. This causes adjacent batteries to heat up, and what could have been locally controlled anomalies to quickly spread throughout the entire storage cabinet, significantly increasing the potential for damage. Furthermore, after an anomaly occurs, operators must approach the cabinet, sometimes even inserting their limbs inside, for manual handling. This is not only inefficient but also poses a direct threat to the personal safety of operators, given the continuous heat generation from the batteries and the risk of splashing or explosion. The persistent existence of these problems has hindered further improvements in the safety and reliability of new energy vehicle power battery storage. Summary of the Invention

[0004] The purpose of this invention is to achieve adaptive flexible limiting of batteries during storage, immediate physical isolation and active suppression under abnormal conditions, and safe and convenient removal of high-risk batteries, thereby comprehensively improving storage safety and emergency handling efficiency. To achieve the above objectives, this invention adopts the following technical solution: A battery storage device based on new energy vehicle production includes a storage cabinet for storing vehicle batteries. The storage cabinet has a rotatable door and multiple storage protection components. Each storage protection component includes a storage cavity on the storage cabinet, a storage box separately installed within the storage cavity, and multiple ventilation holes on both the storage cavity and the storage box. These ventilation holes facilitate the flow of the internal environment of the storage cabinet, ensuring that each vehicle battery is in the same storage environment. An airbag is installed inside the storage box, used for flexibly limiting the vehicle battery. Flame-retardant inert gas circulates within the airbag, and several channels for gas flow are provided on the airbag. The cabinet door is snapped onto the storage box, which is installed separately from the storage box. The airbag monitors the bulging state of the car battery. A smoke temperature sensor for monitoring the car battery status is installed on the top of the inner wall of the storage box. An air valve is installed on the top of the inner wall of the storage box. Inert gas in the airbag is sprayed onto the surface of the car battery through the air valve. A sealing frame is installed inside the storage box to isolate the car battery independently.

[0005] Furthermore, the storage protection assembly also includes limiting grooves that are commonly formed in the storage cavity and at the bottom of the storage box. A limiting frame is fixedly connected to the bottom of the inner wall of the storage box. An airbag is fixedly connected to the inner surface of the limiting frame. Two air tubes are symmetrically fixedly connected to the limiting frame and are connected to the inside of the limiting frame. A pressure sensor is fixedly connected to the limiting frame, and the detection end of the pressure sensor extends into the limiting frame. A shelf is provided on each side of the door and is fixedly connected to the door. Two guide rods are symmetrically fixedly connected to the door. A pull rod is slidably connected to both guide rods. A tension spring is fitted on each of the two guide rods, and the two ends of the tension spring are fixedly connected to the guide rod and the pull rod, respectively.

[0006] Furthermore, an electric push rod is fixedly connected to the side of the storage box away from the door. A sealing frame is fixedly connected to the telescopic shaft end of the electric push rod. Two guide rods are symmetrically fixedly connected to the bottom of the inner wall of the storage box. A sealing plate is slidably connected to the two guide rods. A tension spring is fitted on each of the two guide rods. The two ends of the tension spring are fixedly connected to the guide rod and the sealing plate, respectively. Multiple insert rods are fixedly connected to the bottom of the sealing plate. Two triangular push plates are symmetrically fixedly connected to the side of the sealing frame near the electric push rod. A crossbar is fixedly connected to the side of the sealing frame away from the electric push rod. A locking rod is fixedly connected to the side of the crossbar away from the electric push rod. Four sliding grooves are opened in a ring on the door. A locking plate is slidably connected to each of the four sliding grooves. Multiple tension springs are fixedly connected to each locking plate in a linear array. The end of the tension spring away from the locking plate is fixedly connected to the groove wall. A turntable is rotatably connected to the side of the door away from the locking rod. A torsion spring is fixedly connected between the turntable and the door.

[0007] Furthermore, the limiting frame has a through groove corresponding to the airbag through groove, and two air tubes are used for injecting and depressing air in the limiting frame, respectively.

[0008] Furthermore, the cover has multiple through slots corresponding to the ventilation holes.

[0009] Furthermore, the tie rod is engaged with both shelves.

[0010] Furthermore, the storage cavity and the storage box are provided with multiple limiting grooves, which are engaged with the insertion rod.

[0011] Furthermore, the triangular push plate and the sealing plate are inserted and matched, and the triangular push plate and the insertion rod are misaligned.

[0012] Furthermore, the side of the lock plate closest to the lock bar is designed with a barb shape with a bevel, and the lock bar and the bevel of the lock plate are pressed together.

[0013] Furthermore, multiple tilting rods are arranged in a ring on the turntable, and the tilting rods are pressed and engaged with the end of the locking plate near the turntable.

[0014] Compared with the prior art, the beneficial effects of the present invention are: By designing the storage protection components, airbags are used to limit the movement of the car battery. This not only adapts to car batteries of different shapes and sizes, avoiding damage from hard contact, but also detects abnormalities in the early stages of battery bulging and deformation through subtle fluctuations in the internal flow field pressure. Under normal storage conditions, relying on the continuous flow of inert gas inside the airbag and the pre-reserved through-holes on the surface, the gas maintaining the storage environment inside the cabinet can directly act on the surface of the car battery, ensuring continuous heat exchange efficiency during the flexible limiting process.

[0015] By designing a protective storage component, the system can instantly cut off the connection between the car battery and the overall environment after an anomaly is triggered, physically sealing the risk of thermal runaway within an independent space. This effectively blocks the diffusion of high-temperature harmful gases to adjacent cells and releases inert gases to the surface of the car battery in a directional manner, achieving both isolation and suppression in real time, significantly delaying or preventing further deterioration of abnormal operating conditions.

[0016] By designing the storage protection components, the locking constraints between the abnormal storage unit and the storage cabinet can be released simultaneously with the isolation action. This allows operators to remove the entire high-risk unit and transfer it to a safe disposal area without having to put their hands inside the risky storage cabinet, greatly reducing the risk of secondary injury and the difficulty of operation during emergency response.

A sealing frame 217 is provided inside the storage box 22. The sealing frame 217 is used to independently isolate the car battery 13.

[0021] The storage protection assembly also includes a limiting groove 24 that is opened in both the storage cavity 21 and the bottom of the storage box 22. A limiting frame 25 is fixedly connected to the bottom of the inner wall of the storage box 22. An airbag 26 is fixedly connected to the inner surface of the limiting frame 25. Two air pipes 27 are symmetrically fixedly connected to the limiting frame 25. The air pipes 27 are connected to the inside of the limiting frame 25. A pressure sensor 28 is fixedly connected to the limiting frame 25. The detection end of the pressure sensor 28 extends into the limiting frame 25. A shelf 212 is provided on each side of the door 211. The shelf 212 is fixedly connected to the cabinet door 12. Two guide rods 213 are symmetrically fixedly connected to the door 211. A pull rod 214 is slidably connected to the two guide rods 213. A tension spring 215 is sleeved on each of the two guide rods 213. The two ends of the tension spring 215 are fixedly connected to the guide rod 213 and the pull rod 214, respectively.

[0022] An electric push rod 216 is fixedly connected to the side of the storage box 22 away from the door 211. A sealing frame 217 is fixedly connected to the telescopic shaft end of the electric push rod 216. Two guide rods 218 are symmetrically fixedly connected to the bottom surface of the inner wall of the storage box 22. A sealing plate 219 is slidably connected to both guide rods 218. A tension spring 220 is fitted on each of the two guide rods 218. The two ends of the tension spring 220 are fixedly connected to the guide rod 218 and the sealing plate 219, respectively. Multiple insert rods 221 are fixedly connected to the bottom of the sealing plate 219. Two triangular push plates 217 are symmetrically fixedly connected to the side of the sealing frame 217 closest to the electric push rod 216. 22. A crossbar 223 is fixedly connected to the side of the sealing frame 217 away from the electric push rod 216. A locking rod 224 is fixedly connected to the side of the crossbar 223 away from the electric push rod 216. Four sliding grooves 225 are opened in a ring on the door 211. A locking plate 226 is slidably connected in each of the four sliding grooves 225. Multiple tension springs 227 are fixedly connected in a linear array on each locking plate 226. The end of the tension spring 227 away from the locking plate 226 is fixedly connected to the groove wall of the sliding groove 225. A turntable 228 is rotatably connected to the side of the door 211 away from the locking rod 224. A torsion spring 229 is fixedly connected between the turntable 228 and the door 211.

[0023] Among them, the limiting frame 25 has a through groove corresponding to the through groove of the airbag 26.

[0024] Among them: two air tubes 27 are used to inject air and depress air in the limiting frame 25 respectively. The ends of the two air tubes 27 away from the airbag 26 are connected to an air pump and an inert gas supply device. The jet valve 29 is connected to the external air pump of the air tube 27.

[0025] It should be added that the temperature of the inert gas can be adjusted according to the storage requirements of the car battery 13.

[0026] Among them, the cover 217 has multiple through slots corresponding to the ventilation holes 23.

[0027] Among them, the tie rod 214 is engaged with both shelves 212.

[0028] Among them, the storage cavity 21 and the storage box 22 are provided with multiple limiting grooves 24, and the limiting grooves 24 are inserted and engaged with the insertion rod 221.

[0029] Among them, the triangular push plate 222 and the sealing plate 219 are inserted and matched, and the triangular push plate 222 and the insertion rod 221 are staggered.

[0030] Wherein: the end of the crossbar 223 away from the sealing frame 217 is slidably connected to the storage box 22.

[0031] Wherein: the side of the locking plate 226 near the locking rod 224 is set with a barb shape with a bevel, and the locking rod 224 and the bevel of the locking plate 226 are pressed together.

[0032] It should be noted that both ends of the locking plate 226 extending out of the slide groove 225 extend away from the turntable 228 to block the slide groove 225, preventing the external environment from communicating with the storage cavity 21 through the slide groove 225, and ensuring the environmental stability of the car battery 13 in the storage cavity 21.

[0033] Among them, multiple inclined rods are arranged in a ring on the turntable 228, and the inclined rods are pressed and engaged with the end of the locking plate 226 near the turntable 228.

[0034] Among them, the turntable 228 is located in the center among the four slides 225.

[0035] It should be noted that the storage cabinet 11 has a built-in control system. The control system of the storage cabinet 11 is electrically connected to the air pressure sensor 28, the air valve 29, the smoke temperature sensor 210, and the electric push rod 216. The control system of the storage cabinet 11 can issue an alarm through sound and light signals when the car battery 13 is abnormal.

[0036] In the initial state, that is, before the car battery 13 is placed in the storage cabinet 11 for storage, the structural states of the storage protection assembly are as follows: Storage box 22 is located inside storage cavity 21, with the ventilation hole 23 on storage box 22 aligned with the ventilation hole 23 on storage cavity 21, and the limiting groove 24 on storage cavity 21 aligned with storage box 22. The telescopic shaft of electric push rod 216 is fully retracted, and the through groove on sealing frame 217 is aligned with the ventilation hole 23 on storage cavity 21 and storage box 22. At this time, the internal structures of each storage cavity 21 in storage cabinet 11 are connected, meaning that the temperature and humidity environment inside the storage cavity 21 in storage cabinet 11 is consistent. Triangular push plate 222 does not contact sealing plate 219, tension spring 220 does not undergo elastic deformation, and insertion rod 221 is simultaneously inserted into the limiting groove 24 on storage box 22 and storage cavity 21. That is, through the insertion state of insertion rod 221 and limiting groove 24, storage box 22 is fixedly installed in storage cavity 21, and storage box 22 cannot be removed from storage cavity 21. Remove from 21. The bottom surface of the sealing plate 219 is in contact with the bottom surface of the inner wall of the storage box 22. The airbag 26 is not inflated and is in a contracted state. The box door 211 is engaged with the cabinet door 12. The pull rod 214 is engaged with the two shelves 212. At this time, the box door 211 is limited to the cabinet door 12. The pull rod 214 is located at the bottom end of the two guide rods 213. The tension spring 215 and the tension spring 227 do not produce elastic deformation. The locking rod 224 does not contact or press against the locking plate 226. That is, at this time, the box door 211 has not been installed and connected to the storage box 22. The turntable 228 does not contact or press against the locking plate 226. The four locking plates 226 are located on the side close to each other in the corresponding slide grooves 225. That is, the four locking plates 226 are gathered together at the minimum distance. The torsion spring 229 does not produce elastic deformation.

[0037] When the car battery 13 needs to be stored in the storage cabinet 11, the storage protection component operates as follows: The user rotates the cabinet door 12 off the storage cabinet 11, exposing the storage cavity 21. Since the cabinet door 211 is now confined to the cabinet door 12, the cabinet door 211 rotates synchronously with the cabinet door 12 away from the storage box 22. At this time, the user places the car battery 13 into the limiting frame 25. Then, the user drives the external air pump and inert gas supply device to operate, so that the air pump and inert gas supply device inject inert gas into the airbag 26 through the air tube 27. As the inert gas is continuously injected into the airbag 26, the inert gas gradually fills the airbag 26, causing the airbag 26 to gradually expand inward. During the expansion process, the airbag 26 adheres to the car battery 13, so that the airbag 26 gradually expands to cover the car battery 13. At this time, no more gas is injected into the airbag 26. Through the cooperation of the air pump and the two air tubes 27, the inert gas circulates in the airbag 26. During this process, the expansion state of the airbag 26 remains unchanged, and the airbag 26 maintains the state of covering and flexibly limiting the car battery 13.

[0038] The user then rotates the cabinet door 12 to seal the inside of the storage cabinet 11. At this time, the car battery 13 is stored in the storage cabinet 11. During this process, the user adjusts the temperature and humidity inside the storage cabinet 11 to a suitable storage environment for the car battery 13. Since the storage chambers 21 inside the storage cabinet 11 are connected through the ventilation holes 23, the storage environment of each car battery 13 is connected at this time, ensuring that the storage conditions of each car battery 13 are consistent.

[0039] During the storage of the car battery 13, since the limiting frame 25 and the airbag 26 are both provided with through slots, the gas medium that maintains the storage environment in the storage cabinet 11 can directly act on the surface of the car battery 13 through the through slots, preventing the car battery 13 from overheating due to being wrapped by the airbag 26. Since the inert gas in the airbag 26 is circulating, and the temperature of the inert gas is adjusted by the user to a suitable storage temperature for the car battery 13, a flowing heat exchange is formed on the car battery 13. This, together with the gas acting on the surface of the car battery 13 through the through slots of the limiting frame 25 and the airbag 26, ensures that the car battery 13 is always in a suitable storage environment.

[0040] During this process, the storage protection component monitors the status of the vehicle battery 13, as follows: The smoke temperature sensor 210 located at the top of the inner wall of the storage box 22 constantly monitors the temperature of the car battery 13 and whether smoke is generated. At the same time, the air pressure sensor 28 constantly monitors the air pressure inside the airbag 26. Since the airbag 26 maintains a constant inflation state, that is, the airbag 26 always flexibly wraps and limits the car battery 13, the gas pressure inside the airbag 26 is constant. If the car battery 13 bulges during storage, the bulging car battery 13 will squeeze the airbag 26, thereby causing the air pressure inside the airbag 26 to fluctuate.

[0041] When the air pressure sensor 28 detects air pressure fluctuations inside the airbag 26 or the smoke temperature sensor 210 detects abnormal temperature or smoke generation, the electric push rod 216 starts operating. The telescopic shaft of the electric push rod 216 extends accordingly, pushing the cover 217 towards the door 211. As the cover 217 moves, the through slot and ventilation hole 23 on the cover 217 are misaligned, causing the ventilation hole 23 to be covered and blocked by the cover 217. At this time, the storage box 22 where the abnormal car battery 13 is located is independent of the other storage boxes 22, preventing the abnormal car battery 13 from interfering with the other storage boxes 22.

[0042] As the sealing frame 217 moves, the jet valve 29 ejects the inert gas from the airbag 26, allowing the inert gas to be directly sprayed onto the surface of the car battery 13. This enables immediate treatment of the car battery 13 at the initial stage of the abnormality, achieving flame retardant and cooling effects, which helps prevent the abnormality of the car battery 13 from worsening. Simultaneously, it releases the airbag 26 from its inflated state surrounding the car battery 13, preventing the airbag 26 from being interfered with by the abnormal car battery 13.

[0043] During the movement of the sealing frame 217, the sealing frame 217 drives the triangular push plate 222 to move synchronously, so that the inclined surface of the triangular push plate 222 abuts against and squeezes the sealing plate 219. Under the guidance of the inclined surface of the triangular push plate 222, the sealing plate 219 slides upward on the guide rod 218, and at the same time, the tension spring 220 undergoes elastic deformation. As the sealing plate 219 moves upward, the sealing plate 219 drives the insertion rod 221 to move upward, so that the insertion rod 221 is pulled out from the limiting groove 24. At this time, the limiting state between the storage box 22 and the storage cavity 21 is released.

[0044] Reference Figure 9 As shown, the movement of the sealing frame 217 simultaneously moves the crossbar 223, causing it to slide within the storage box 22 towards the door 211. The crossbar 223 also drives the locking rod 224 to move synchronously, causing it to abut against and press against the inclined surface of the locking plate 226. Guided by the inclined surface of the locking plate 226, the four locking plates 226 slide away from each other within their corresponding grooves 225, simultaneously causing the tension spring 227 to undergo elastic deformation. With the continuous movement of the locking rod 224... When the locking bar 224 moves to the inclined surface of the locking plate 226, the locking plate 226 is no longer squeezed by the locking bar 224. Then, under the elastic reset action of the tension spring 227, the four locking plates 226 are pushed in the direction of mutual convergence, so that the locking plates 226 are engaged with the side of the locking bar 224 near the crossbar 223. Since the locking plates 226 are set as barbs, the locking bar 224 is limited by the four locking plates 226 through the barbs. That is, at this time, the door 211 and the storage box 22 are connected as one unit.

[0045] When an abnormality is detected in the car battery 13, the control system of the storage cabinet 11 alerts the staff through audible and visual signals. When the staff handles the abnormal car battery 13, they pull the lever 214 upwards, causing it to slide upwards on the guide rod 213. At the same time, the tension spring 215 undergoes elastic deformation, and the lever 214 moves upwards to disengage from the shelf 212. Consequently, the door 211 is released from the restriction of the cabinet door 12. The staff then pulls the lever 214 away from the cabinet door 12. Since the door 211 is now connected to the storage box 22 as a whole, and the restriction between the storage box 22 and the storage cavity 21 is released, the staff can directly pull the storage box 22 out of the storage cavity 21. At this time, the abnormal car battery 13 is pulled out along with the storage box 22.

[0046] As the storage box 22 detaches the car battery 13 from the storage cabinet 11, the malfunctioning car battery 13 is then independently stored in a sealed enclosure formed by the door 211 and the storage box 22. To prevent a chain reaction, the car battery 13 is detached from the storage cabinet 11. Workers can move the enclosure to a safe processing area. During this process, the malfunctioning car battery 13 remains encased in an inert gas environment. When workers need to remove the malfunctioning car battery 13, they rotate the turntable 228. The torsion spring 229 then undergoes elastic deformation, causing the tilting rod of the turntable 228 to press against and compress the four locking plates 226. Guided by the inclined surface of the turntable 228, the turntable 228 pushes the four locking plates 226 apart, thus removing the locking plates 226 from the locking rod 224 and releasing the restriction between the door 211 and the storage box 22. Workers can then directly remove the door 211 from the storage box 22, exposing the car battery 13 for easy removal and processing.

[0047] After the car battery 13 is removed, the user can place the storage box 22 back into the storage cavity 21 to facilitate the storage of the remaining car batteries 13, as follows: The user places the storage box 22 into the storage cavity 21. When the storage box 22 moves to the point where the insertion rod 221 aligns with the limiting groove 24, the operator drives the electric push rod 216 to retract its telescopic shaft, causing the sealing frame 217 to move in the direction of the electric push rod 216. Consequently, the triangular push plate 222 stops pressing and lifting the sealing plate 219. At this time, under the elastic contraction of the tension spring 220, the sealing plate 219 drives the insertion rod 221 to move down, so that the insertion rod 221 is inserted into the limiting groove 24, thereby locking and limiting the storage box 22 and the storage cavity 21. As the sealing frame 217 moves, the through groove on the sealing frame 217 realigns with the ventilation hole 23, so that the storage cavity 21 is connected to the interior of the other storage cavities 21.

[0048] After completion, the user pulls the lever 214 upwards and engages the cabinet door 211 with the cabinet door 12. After completion, the user stops pulling the lever 214, and under the elastic reset action of the tension spring 215, the lever 214 is engaged in the shelf 212. At this time, the cabinet door 211 is limited to the cabinet door 12, and the reset of each structure in the storage protection component is completed.

[0049] In summary, the following beneficial effects can be achieved through the design of storage protection components: By designing the storage protection components, an airbag 26 is used to limit the position of the car battery 13. This not only adapts to car batteries 13 of different shapes and sizes, avoiding damage from hard contact, but also detects abnormalities in the early stages of battery bulging and deformation through subtle fluctuations in the internal flow field pressure. Under normal storage conditions, relying on the inert gas continuously flowing inside the airbag 26 and the pre-reserved through air channels on the surface, the gas maintaining the storage environment inside the cabinet can directly act on the surface of the car battery 13, ensuring continuous heat exchange efficiency during the flexible limiting process.

[0050] By designing a storage protection component, the connection path between the vehicle battery 13 and the overall environment can be instantly cut off after an anomaly is triggered, physically sealing the risk of thermal runaway within an independent space. This effectively blocks the diffusion of high-temperature harmful gases to adjacent units and releases inert gas directionally to the surface of the vehicle battery 13, achieving both isolation and suppression in real time, significantly delaying or preventing further deterioration of the abnormal operating conditions.

[0051] By designing the storage protection components, while implementing isolation actions, the locking constraints between the abnormal storage unit and the storage cabinet 11 are released through linkage and coordination. This allows operators to remove the entire high-risk unit and transfer it to a safe disposal area without having to put their hands inside the risky storage cabinet 11, greatly reducing the risk of secondary injury and the difficulty of operation during emergency handling.

[0052] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
