[0025] Combination Figures 1 to 5 As shown, one embodiment of the present invention provides a battery structure, including: A housing, wherein a battery cell 110 is disposed inside the housing; A circuit board 120 is disposed on the housing, and the battery cell 110 is electrically connected to the circuit board 120; A protective structure body 200, wherein the protective structure body 200 is mounted on the circuit board 120; The storage module 400 is installed in the protection structure body 200 and is electrically connected to the circuit board 120 for storing battery parameter information.

[0026] A battery structure of the present invention provides preliminary protection for a storage module 400 through a protective structure body 200. The protective structure body 200 can produce a heat-insulating effect after a battery fire occurs to prevent the storage module 400 from being burned. The storage module 400 stores the real-time operating parameters of the battery. After a fire occurs, the storage module 400 is found. 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, which plays a key role in restoring the scene and avoiding problems in the later stages of the product.

[0027] 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, which can better protect the storage module 400.

[0028] In one embodiment, a heat insulating component 300 is also included; A heat insulating component 300, wherein the heat insulating component 300 is installed in the protective structure body 200; Wherein, the heat insulating component 300 is made of high temperature resistant material.

[0029] In this embodiment, the storage module 400 can be provided with secondary protection 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. In addition, 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.

[0030] In one embodiment, the protective structure body 200 includes a protective shell 210 and a shell cover 220; The housing cover 220 is fixedly connected to the top of the protective housing 210; An accommodation space is formed between the protective housing 210 and the housing cover 220; The circuit board 120 begins to have an opening whose size matches that of the protection structure body 200 .

[0031] 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 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 invention solves this problem well.

[0032] 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, which is not limited here.

[0033] 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.

[0034] 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.

[0035] In one embodiment, the protective housing 210 and the housing cover 220 are made of ceramic aluminum, aluminum oxide, magnesium brick, or silicon carbide.

[0036] In this embodiment, ceramic aluminum is a new type of material, which is formed by combining ceramic and aluminum. It has the toughness and plasticity of aluminum and the strength of ceramic. It is light in weight, high in strength, heat-resistant and non-combustible. Therefore, ceramic aluminum as the material of the protective shell 210 and the shell cover 220 can well ensure the safety of the storage module 400. Alumina has heat resistance, which is one of its many advantages. This allows alumina to maintain good performance and structural stability in high temperature environments. In addition, alumina also has the characteristics of low thermal expansion coefficient, high mechanical strength and good thermal conductivity, which further enhances its application potential in high temperature environments. As the material of the protective housing 210 and the housing cover 220, it can well ensure the safety of the storage module 400. The heat-resistant advantages of magnesia bricks mainly include high melting point, good high temperature resistance, good thermal shock resistance and low high temperature creep. 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 erosion 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. The heat-resistant advantages of silicon carbide are mainly reflected in its high 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.

[0037] In one embodiment, the storage module 400 is located on the top of the thermal insulation component 300 .

[0038] 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 the storage module 400 from being damaged. 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.

[0039] In one embodiment, the thermal insulation component 300 is made of quartz wool, silicate, foam board, fiber board, or ultra-fine glass wool.

[0040] In this embodiment, the heat resistance of quartz wool is due to its unique physical and chemical properties. It has high tensile strength (‌7GPa)‌ and high tensile modulus (‌70GPa)‌, which ensure that it can maintain high strength and dimensional stability in high temperature environments, thereby protecting the storage module 400 well; The thermal insulation component 300 made of silicate can be used for a long time in a high temperature environment without obvious performance degradation. This material can maintain stable performance under high temperature conditions, ensuring the normal operation of the equipment under extreme temperatures, thereby well protecting the storage module 400. Foam board, compared with ordinary foam materials, foam board will not melt due to high temperature, so it can still maintain its original shape and structure in a high temperature environment, ensuring its use effect and safety, so as to well protect the storage module 400; The fiberboard has good water resistance and heat resistance, thanks to the combination of cellulose fiber and additives such as asphalt, which enables the fiberboard to effectively isolate moisture erosion and has high temperature stability, and can be used for a long time in a high temperature environment, thereby well protecting the storage module 400; 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 properties and enhancing its heat resistance, thereby protecting the storage module 400 well.

[0041] In one embodiment, an FPC flexible cable 500 is disposed on the storage module 400 .

[0042] In one embodiment, the FPC flexible cable 500 passes through the protective structure body 200 and extends outside the protective structure body 200; The FPC flexible cable 500 is used to connect to an external battery structure.

[0043] 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.

[0044] It should be noted that the FPC flexible cable 500 has a relatively small thickness and will not affect the sealing of the accommodation space after being squeezed by the protective housing 210 and the housing cover 220 . This is explained here.

[0045] In one embodiment, the heat-resistant temperature of the protective structure body 200 is greater than 2000 degrees Celsius, and 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.

[0046] One embodiment of the present invention provides a method for protecting battery data, comprising: The battery structure according to any one of the above embodiments; and Steps to protect battery data: The protective structure body 200 provides preliminary protection for the storage module 400, and the protective structure body 200 produces a heat insulation effect after the battery catches fire; 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.

[0047] Working principle of the present invention: 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 secondarily protected by the heat-insulating component 300, thereby better ensuring 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 an external smart device, the battery parameters are checked through the smart device and the cause of the accident is analyzed.

[0048] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the paper document and the contents of the drawings of the present invention under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
