[0046] Combine Figures 1 to 5 As shown, one embodiment of the present invention provides a battery structure, including:

[0047] A housing, wherein a battery cell 110 is disposed inside the housing;

[0048] A circuit board 120 is provided on the housing, and the battery cell 110 is electrically connected to the circuit board 120;

[0049] A protective structure body 200 , wherein the protective structure body 200 is mounted on the circuit board 120 ;

[0050] The storage module 400 is installed in the protective structure body 200 and is electrically connected to the circuit board 120 for storing battery parameter information.

[0051] A battery structure of the present invention provides preliminary protection for the storage module 400 through the protective structure body 200. The protective structure body 200 can produce a heat-insulating effect after the battery catches fire to prevent the storage module 400 from being burned. The storage module 400 stores the real-time operating parameters of the battery. After the fire occurs, the storage module 400 is found. After the storage module 400 is connected to an external smart device, the battery parameters are viewed through the smart device and the cause of the accident is analyzed, which plays a key role in restoring the scene and avoiding and improving problems in the later stage of the product.

[0052] It should be noted that the housing is used to install the protective structure body 200 so that the storage module 400 and the electrical housing are not installed in an integrated manner, thereby better protecting the storage module 400.

[0053] In one embodiment, a heat insulating component 300 is further included;

[0054] A heat insulating component 300 , the heat insulating component 300 being installed in the protective structure body 200 ;

[0055] Wherein, the heat insulating component 300 is made of high temperature resistant material.

[0056] In this embodiment, the thermal insulation component 300 can provide secondary protection for the storage module 400, which can better ensure the safety of the storage module 400 after the equipment loaded with the battery catches fire. The thermal insulation component 300 also provides a certain buffer for the storage module 400 after the equipment loaded with the battery is hit, thereby better preventing the storage module 400 from being damaged after the collision.

[0057] In one embodiment, the protective structure body 200 includes a protective shell 210 and a shell cover 220;

[0058] The housing cover 220 is fixedly connected to the top of the protective housing 210;

[0059] An accommodating space is formed between the protective housing 210 and the housing cover 220;

[0060] The circuit board 120 begins to have an opening that matches the size of the protective structure body 200 .

[0061] In this embodiment, the accommodating space is a closed space. If it is not a closed space, the storage module 400 will still be damaged after the battery catches fire. The protective shell 210 is a conical shell, which can be easily placed in the opening of the circuit board 120 and then fixed. If it is a conventional rectangular parallelepiped or cube, it is easy to fall directly when placed in the opening, and the installer needs to fix the protective shell 210 for the first time and then complete the final fixation. The present utility model solves this problem very well.

[0062] It should be noted that the above-mentioned fixed connection can be bolted, welded or other methods that can fix the outer shell cover 220 to the protective shell 210, and is not limited here.

[0063] Furthermore, generally, the storage module 400 is integrally formed with the battery module, and is mainly used for protection outside the battery module. Therefore, when the battery module catches fire, the storage module 400 cannot be well protected, and the cause of the battery fire cannot be determined. The present invention installs a protective structure body 200 on the circuit board 120, and the storage module 400 is located in the protective structure. When the battery cell 110 catches fire, the storage module 400 can be protected by the protective structure body 200. Compared with the structure in which the storage module 400 is integrally formed with the battery module, the present invention can well protect the storage module 400.

[0064] Furthermore, a sealing ring is provided between the protective housing 210 and the housing cover 220. This is a conventional setting, so it is not described in the claims and is explained here.

[0065] In one embodiment, the protective housing 210 and the housing cover 220 are both made of ceramic aluminum, aluminum oxide, magnesium brick, or silicon carbide.

[0066] In this embodiment, ceramic aluminum is a new material formed by combining ceramic and aluminum. It has the toughness and plasticity of aluminum and the strength of ceramic. It is lightweight, high in strength, heat-resistant and non-combustible. Therefore, ceramic aluminum as the material of the protective housing 210 and the housing cover 220 can effectively ensure the safety of the storage module 400.

[0067] Alumina's heat resistance is one of its many advantages, allowing it to maintain good performance and structural stability even in high-temperature environments. Furthermore, alumina has a low thermal expansion coefficient, high mechanical strength, and good thermal conductivity, further enhancing its potential for application in high-temperature environments. As the material for the protective housing 210 and the housing cover 220, alumina can effectively ensure the safety of the storage module 400.

[0068] The heat-resistant advantages of magnesia bricks include a high melting point, good high-temperature resistance, good thermal shock resistance, and low high-temperature creep. Magnesia bricks have a high melting point and good high-temperature resistance. The main crystal phase of magnesia bricks is periclase, which has the typical characteristics of general alkaline refractory products. Its refractoriness is above 3000 degrees Celsius, and it can effectively resist corrosion in high-temperature environments. As the material of the protective shell 210 and the shell cover 220, it can well ensure the safety of the storage module 400.

[0069] The heat-resistant advantages of silicon carbide are mainly reflected in its high temperature resistance, high thermal conductivity, corrosion resistance, high strength and high rigidity. Silicon carbide can work stably for a long time in a high-temperature environment of up to 2700 degrees Celsius, showing its excellent high-temperature resistance. As the material of the protective shell 210 and the shell cover 220, it can well ensure the safety of the storage module 400.

[0070] In one embodiment, the storage module 400 is located on top of the thermal insulation component 300 .

[0071] In this embodiment, after the storage module 400 is installed on the thermal insulation component 300, after the protective structure body 200 is hit, most of the force will be absorbed by the thermal insulation component 300, thereby effectively preventing damage to the storage module 400. The thermal insulation component 300 can also isolate most of the heat to prevent excessive heat after the battery catches fire, thereby causing damage to the storage module 400.

[0072] In one embodiment, the thermal insulation component 300 is made of quartz wool, silicate, foam board, fiber board, or ultra-fine glass wool.

[0073] In this embodiment, the heat resistance of quartz wool is due to its unique physical and chemical properties. It has high tensile strength (7 GPa) and high tensile modulus (70 GPa). These properties ensure that it can maintain high strength and dimensional stability in high temperature environments, thereby effectively protecting the storage module 400.

[0074] The thermal insulation component 300 made of silicate can be used for a long time in a high temperature environment without showing any significant performance degradation. This material can maintain stable performance under high temperature conditions, ensuring the normal operation of the equipment under extreme temperatures, thereby effectively protecting the storage module 400.

[0075] Compared with ordinary foam materials, foam boards do not melt due to high temperatures. This allows them to maintain their original shape and structure in high-temperature environments, ensuring their effectiveness and safety, thereby effectively protecting the storage module 400.

[0076] The fiberboard has excellent water resistance and heat resistance, thanks to the combination of cellulose fibers and additives such as asphalt. This allows the fiberboard to effectively isolate moisture from erosion. It also has high-temperature stability and can be used for long periods of time in high-temperature environments, thereby effectively protecting the storage module 400.

[0077] The fibers of the ultra-fine glass wool are three-dimensionally cross-entangled to form a large number of tiny pores and holes that are connected inside and outside, giving it excellent thermal insulation performance and enhancing its heat resistance, thereby effectively protecting the storage module 400.

[0078] In one embodiment, an FPC cable 500 is disposed on the storage module 400 .

[0079] In one embodiment, the FPC cable 500 passes through the protective structure body 200 and extends outside the protective structure body 200;

[0080] The FPC flexible cable 500 is used to connect to an external battery structure.

[0081] In this embodiment, the FPC flexible cable 500 is used as the wiring to reduce the damage to the chip caused by the external high temperature being transmitted to the storage module 400 through the connecting wire.

[0082] It should be noted that the FPC flexible cable 500 is relatively thin and will not affect the sealing of the accommodation space after being squeezed by the protective shell 210 and the shell cover 220 . This is explained here.

[0083] In one embodiment, the heat-resistant temperature of the protective structure body 200 is greater than 2000 degrees Celsius. A detection module 410 is installed on the storage module 400. The detection module 410 is used to detect abnormal data of the battery and transmit it to the storage module 400.

[0084] One embodiment of the present invention provides a method for protecting battery data, including:

[0085] The battery structure according to any one of the above embodiments; and

[0086] Steps to protect battery data:

[0087] The protective structure body 200 provides preliminary protection for the storage module 400 and produces a heat insulation effect after the battery catches fire;

[0088] The storage module 400 stores the real-time operating parameters of the battery. After a fire occurs, the storage module 400 is searched for. After the storage module 400 is connected to an external smart device, the battery parameters are checked through the smart device and the cause of the accident is analyzed.

[0089] The working principle of this utility model:

[0090] The storage module 400 is initially protected by the protective structure body 200. The protective structure body 200 can produce a heat-insulating effect after the battery catches fire, thereby preventing the storage module 400 from being burned. The storage module 400 can be secondary protected by the heat-insulating component 300, which can better ensure the safety of the storage module 400 after the equipment loaded with the battery catches fire. The heat-insulating component 300 provides a certain buffer for the storage module 400 after the equipment loaded with the battery is hit, thereby better preventing the storage module 400 from being damaged after the collision. After the fire, the storage module 400 is found, and after the storage module 400 is connected to the external smart device, the battery parameters are checked through the smart device and the cause of the accident is analyzed.
