Description

Technical Field

[0001] The utility model relates to the field of storage batteries, and particularly relates to a household energy storage structure with a fire extinguishing function. Background Art

[0002] When storing backup electric energy in daily household life, a battery pack is required to store the electric energy. In recent years, the household energy storage industry has entered a period of rapid development. While users pursue the cost performance of energy storage devices, they also pay more and more attention to the safety of battery use. In this context, each manufacturer tends to choose a safer chemical system and has done a lot of work in circuit thermal management. Among them, considering cost, a protective cabinet is mainly used to isolate the battery from the outside world, prevent the battery from being affected by the outside temperature, or isolate the battery from the outside world when an accident occurs to prevent the battery from coming into contact with external combustibles and expanding the fire. However, using a protective cabinet cannot solve the problem of rapid fire extinguishing. Specifically, due to manufacturing problems, the battery cells are prone to thermal runaway, and a fire source is formed inside the battery cells to bake the protective cabinet, still unable to block the fire within a certain period of time.

[0003] To solve the above problems, the prior art provides many solutions. For example, the existing patent WO2022134748A1 provides a lithium battery explosion-proof box device, which sets up a lifting plate scheme to ensure the safety of the battery pack, and a fire extinguishing patch is arranged on the battery pack of the device to automatically extinguish the fire. Another example is that the existing patent KR1020230009183 discloses a photovoltaic array module embedded with a bypass diode. The bypass diode includes a bypass diode and a connector that prevent the occurrence and spread of fire by combining a fireproof patch, a junction box cover that protects the diode and the connector, and a junction box that fixes the diode to the solar cell module. However, there is still room for improvement in the layout scheme of the fire extinguishing patch in the above-mentioned patented devices. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a household energy storage structure with a fire extinguishing function, which can control the fire in the battery storage space, block the fire in time and extinguish the fire, and set up a multi-level fire extinguishing scheme to ensure the safety of the household energy storage structure.

[0005] To solve the above technical problems, the utility model specifically provides the following technical solutions: A household energy storage structure with a fire extinguishing function includes a first frame with a rectangular frame structure. The upper and lower parts of the first frame are sealed by setting first sealing plates. A partition plate is arranged inside the first frame to divide its internal space. Single-core batteries are arranged in the divided space inside the first frame.

[0006] A first matrix capable of suppressing thermal runaway and extinguishing fire is attached to the surface of the partition plate.

[0007] In the present invention, the first frame space for placing single-core batteries is separated by a partition plate, thereby reducing the possibility of fire source spread. For example, if a fire breaks out in a single-core battery within one of the separated spaces, the fire can be controlled within that separated space to prevent the fire from spreading. Moreover, a fire extinguishing patch is provided on the partition plate, which can timely block the fire and extinguish it. Thus, a multi-level fire extinguishing and fire control scheme is set up to effectively ensure the safety of the household energy storage structure.

[0008] According to an embodiment of the present invention, through holes penetrating through are arranged in an array on the surface of the partition plate, and the through holes can communicate the internal space of the first frame separated by the partition plate. The way of arranging the through holes on the surface of the partition plate can enable the air flow in the separated spaces to communicate with each other, which helps to balance the temperature inside the entire first frame.

[0009] According to an embodiment of the present invention, first through holes are opened on the upper and lower surfaces of the first frame, and the first sealing plate is provided with mounting holes corresponding to the first through holes. The first sealing plate can be installed and fixed to the first frame by fasteners passing through the first through holes and the mounting holes, thereby encapsulating the single-core battery to place or reduce external interference, especially the influence of high temperature.

[0010] According to an embodiment of the present invention, the first base body has any one of the structural shapes of a circle, polygon, sphere, cylinder, prism, circular ring, rectangle, etc. The first base body can be in various forms, which can play the role of extinguishing fire and suppressing temperature for single-core batteries of different sizes. Of course, the structural form of the first base body in the present invention is not limited to the above structural shapes, and can also be a special-shaped structure. For some special installation spaces, a first base body with a structural form corresponding to the structure of the corresponding installation space will be designed.

[0011] According to an embodiment of the present invention, clamping assemblies are symmetrically arranged on the same side surface of the single-core battery. The clamping assembly has a first mounting plate connected to the side surface of the single-core battery, and the first mounting plate is connected with a second mounting plate arranged perpendicular to the side surface of the single-core battery. On the opposite surfaces of the second mounting plates of the two clamping assemblies, limiting strip plates are arranged at intervals, and the first base body can be placed in the space between the limiting strip plates at intervals. In the existing fire extinguishing iron sheets, there is a situation of directly attaching to the surface of the single-core battery. This attachment method may affect the heat dissipation of the single-core battery and it is difficult to disassemble the fire extinguishing patch. The clamping assembly set in the present invention uses a clamping method to arrange the first base body with a fire extinguishing function on one side of the single-core battery, which can ensure the heat dissipation of the single-core battery. Specifically, through the first mounting plate, there is a spacing distance between the first base body and the single-core battery, and there is also a spacing space between adjacent first base bodies, so as to ensure the heat dissipation space. Moreover, the clamping assembly and the single-core battery are not connected by a pasting method, which is convenient for disassembly.

[0012] According to an embodiment of the present invention, at least two first substrates are placed on two clamping assemblies, and the distances between each first substrate and the adjacent single-cell battery are different. Setting multiple first substrates and designing the distance scheme of the first substrate relative to the single-cell battery can ensure the fire extinguishing effectiveness. In the case of a fire in a single-cell battery, the adjacent first substrate reacts to extinguish the fire. There may be a shortage of first substrates, especially in the prior art where only one fire extinguishing patch is provided. The present invention provides multiple first substrates with fire extinguishing functions to provide sufficient fire extinguishing materials for the fire source point to extinguish the fire. Moreover, the first substrates are arranged at intervals, so that the fire extinguishing reactions of the first substrates are spaced apart to continuously extinguish the fire and prevent re-ignition.

[0013] According to an embodiment of the present invention, the first mounting plate has a limiting plate connected to the single-cell battery. The limiting plate has an extension plate, and the extension plate can be arranged in contact with the side surface of the single-cell battery. Circular holes are formed on the surface of the limiting plate and / or the extension plate, and the limiting plate and / or the extension plate can be connected to the single-cell battery through fasteners in cooperation with the circular holes. The design of the limiting plate can realize the quick assembly and disassembly of the clamping assembly and the single-cell battery. There is no need to use materials such as glue to realize the assembly of the clamping assembly, avoiding the problem of difficult subsequent disassembly and assembly. Moreover, this can also quickly adjust the distance between the two clamping assemblies to adapt to the use of first substrates of different sizes.

[0014] According to an embodiment of the present invention, a first substrate is provided between the first sealing plate and the single-cell battery. It is used to realize the fire extinguishing prevention and control of the upper and lower end faces of the single-cell battery.

[0015] According to an embodiment of the present invention, a support assembly is specifically provided on the side surface of the first substrate arranged between the first sealing plate and the single-cell battery. The support assembly has an elastic member in contact with the first sealing plate. The end of the elastic member is connected to a first support plate in contact with the surface of the first substrate, and the second support plate is hinged to the side surface of the support plate. The support assembly is used to effectively attach the first substrate with a fire extinguishing function to the surface of the single-cell battery. Moreover, the elastic member has an elastic function and will not cause the first substrate to be extruded and deformed. The first support plate and the second support plate are used to ensure an effective support contact area.

[0016] Compared with the prior art, the present utility model has the following beneficial effects: The present invention divides the first frame space for placing single-cell batteries through a partition plate, thereby reducing the possibility of fire source diffusion. For example, if a fire occurs in a single-cell battery in one of the partitioned spaces, the fire can be controlled within that partitioned space to avoid the spread of the fire. Moreover, the partition plate is equipped with a fire extinguishing patch that can timely block the fire and extinguish it. Such a multi-level fire extinguishing and fire control scheme is effectively ensured to ensure the safety of the household energy storage structure. Description of the Drawings

[0030] Embodiment 1

[0031] As Figures 1-8 shown, a household energy storage structure with a fire extinguishing function includes a first frame 10 of a rectangular frame structure. The upper and lower parts of the first frame 10 are sealed by setting first sealing plates 20. A partition plate 30 for partitioning the internal space is provided inside the first frame 10. Single-core batteries 40 are arranged in the partitioned space inside the first frame 10.

[0032] A first substrate 60 capable of suppressing thermal runaway and extinguishing fire is attached to the surface of the partition plate 30.

[0033] In the present invention, the space of the first frame 10 where the single-core batteries 40 are placed is partitioned by the partition plate 30, thus reducing the possibility of fire source spread. For example, if a fire occurs in the single-core battery 40 in one of the partitioned spaces, the fire can be controlled within that partitioned space to prevent the fire from spreading. And the partition plate 30 is equipped with a fire extinguishing patch that can timely block the fire and extinguish it. Such a multi-level fire extinguishing and fire control scheme is set up to effectively ensure the safety of the household energy storage structure.

[0034] Through holes that penetrate through are arranged in an array on the surface of the partition plate 30. The through holes can communicate the internal space of the first frame 10 partitioned by the partition plate 30. The way of setting through holes on the surface of the partition plate 30 can enable the airflows in the partitioned spaces to communicate with each other, which helps to balance the temperature inside the entire first frame 10.

[0035] First through holes 11 are opened on the upper and lower surfaces of the first frame 10, and the first sealing plate 20 is provided with mounting holes corresponding to the first through holes 11. The first sealing plate 20 can be installed and fixed to the first frame 10 by fasteners passing through the first through holes 11 and the mounting holes, thus encapsulating the single-core batteries 40 to prevent or reduce external interference, especially the influence of high temperature.

[0036] The first substrate 60 can be any one of the structural shapes of circular, polygonal, spherical, cylindrical, prismatic, circular ring-shaped, and rectangular. The first substrate 60 can be in various forms and is used to extinguish fires and suppress temperatures for single-core batteries 40 of different sizes. Of course, the structural form of the first substrate 60 in the present invention is not limited to the above structural shapes and can also be a special-shaped structure. For some special installation spaces, a first substrate 60 with a structural form corresponding to the structure of the corresponding installation space will be designed.

[0037] Clamping assemblies 50 are symmetrically arranged on the same side surface of the single-core battery 40. The clamping assembly 50 has a first mounting plate 52 connected to the side surface of the single-core battery 40. The first mounting plate 52 is connected to a second mounting plate 54 arranged perpendicular to the side surface of the single-core battery 40. On the opposite surfaces of the second mounting plates 54 of the two clamping assemblies 50, limiting strip plates 53 are arranged at intervals. The first substrate 60 can be placed in the space between the limiting strip plates 53 at intervals. In the existing fire extinguishing iron sheets, there is a situation of directly attaching to the surface of the single-core battery 40. This attachment method may affect the heat dissipation of the single-core battery 40 and it is difficult to remove the fire extinguishing sticker. The clamping assembly 50 provided in the present invention uses a clamping method to arrange the first substrate 60 with a fire extinguishing function on one side of the single-core battery 40, so as to ensure the heat dissipation of the single-core battery 40. Specifically, a distance is provided between the first substrate 60 and the single-core battery 40 through the first mounting plate 52, and there is also an interval space between adjacent first substrates 60, so as to ensure a heat dissipation space. Moreover, the clamping assembly 50 and the single-core battery 40 are not connected by a pasting method, which is convenient for disassembly.

[0038] At least two first substrates 60 are placed on the two clamping assemblies 50, and the distance between each first substrate 60 and the adjacent single-core battery 40 is different. Setting multiple first substrates 60 and designing the distance scheme of the first substrate 60 relative to the single-core battery 40 can ensure the fire extinguishing effectiveness. In the case of a fire in the single-core battery 40, the adjacent first substrates 60 will react to extinguish the fire. There may be a situation where the first substrates 60 are insufficient, especially in the prior art where only one fire extinguishing sticker is provided. The present invention provides multiple first substrates 60 with a fire extinguishing function, which can provide sufficient fire extinguishing materials for the fire source point to extinguish the fire. Moreover, the first substrates 60 are arranged at intervals, so that the fire extinguishing reaction intervals of the first substrates 60 are formed to continuously extinguish the fire and prevent re-ignition.

[0039] The first mounting plate 52 has a limiting plate 51 connected to the single-cell battery 40. The limiting plate 51 has an extension plate, and the extension plate can be arranged in contact with the side surface of the single-cell battery 40. Circular holes are provided on the surface of the limiting plate 51 and / or the extension plate, and the limiting plate 51 and / or the extension plate can be connected to the single-cell battery 40 through fasteners in cooperation with the circular holes. The design of the limiting plate 51 enables the clamping assembly 50 to be quickly assembled and disassembled with the single-cell battery 40, without using materials such as glue to achieve the assembly of the clamping assembly 50, avoiding the problem of difficult subsequent disassembly and assembly. Moreover, the distance between the two clamping assemblies 50 can also be quickly adjusted to adapt to the use of the first base body 60 of different sizes.

[0040] A first base body 60 is provided between the first sealing plate 20 and the single-cell battery 40, which is used to achieve fire prevention and control of the upper and lower end faces of the single-cell battery 40.

[0041] On the side of the first base body 60 provided between the first sealing plate 20 and the single-cell battery 40, there is specifically a support assembly 70. The support assembly 70 has an elastic member 71 in contact with the first sealing plate 20. The end of the elastic member 71 is connected to a first support plate 72 in contact with the surface of the first base body 60, and a second support plate 73 is hinged to the side of the support plate 72. The support assembly 70 is used to effectively fit the first base body 60 with the fire extinguishing function on the surface of the single-cell battery 40, and the elastic member 71 has an elastic function and will not cause the first base body 60 to be extruded and deformed. The first support plate 72 and the second support plate 73 are used to ensure an effective support contact area.

[0042] It should be noted that the solution of this case is not limited to the fire prevention and extinguishing of the energy storage structure for household appliances, but can also be used for the fire prevention and extinguishing of the energy storage structure with a power storage device used by enterprises.

[0043] The first base body 60 is prepared from a fire extinguishing material, including but not limited to the fire extinguishing materials of the following patents: CN114748830 A and CN 114736554 A.
