Explosion-proof mobile phone cover structure

The present invention relates to a structure for preventing explosion of a lithium battery in a mobile phone or an electronic product.

A lithium battery in a chemical battery is a lithium metal or a lithium alloy as an anode material, and a battery using a nonaqueous electrolyte solution. The lithium battery is different from the lithium ion battery. The former is a primary battery, and the latter is a rechargeable battery. In addition, the first person to invent a lithium battery was Edison, which used the following reaction formula: Li + MnO ₂ = LiMnO ₂ , which is a redox reaction discharge. Nowadays, lithium batteries have become the mainstream. At present, the main cathode materials for lithium-ion batteries are LiCoO2, LiMn2O4, LiNiO2 and LiFePO4, which are widely used in notebook computers, cameras, mobile phones, cameras, and consumer electronics. .

At present, lithium batteries have been used in more and more electronic products due to their small size, light weight, high energy density, insignificant memory effect, and slow charge loss when not in use. Lithium-ion batteries are becoming more and more popular, and can be used in military, pure electric vehicles and aerospace applications. However, lithium batteries have many defects, such as short cycle life, complicated charging circuit, and internal protection circuit for batteries. The requirements are extremely high.

At present, various lithium batteries commonly used in the market are quite different from the designs of nickel-hydrogen and nickel-cadmium batteries. The tops of nickel-hydrogen and nickel-cadmium batteries have exhaust holes designed to decompress and decompress, while lithium batteries are aluminum. In a fully hermetically sealed package, especially for fully encapsulated aluminum-encapsulated lithium batteries, there is an extremely dangerous defect in their safety protection design: when some physical anomalies occur inside the battery, or when internal battery protection chips occur In the event of a fault, it is easy to cause an explosion due to a sudden increase in the internal pressure of the battery. If the lithium battery is improperly used, such as overheating, overcharging, overdischarging or short circuit, the active substance and electrolyte inside the battery under abuse conditions. Chemical changes and electrochemical reactions will occur between the components, and a large amount of heat and gas will be generated. When it continues to accumulate to a certain extent, it will cause the battery to overheat, catch fire or even explode. The risk of bombing makes people's personal safety and property harmed.

There are several reasons for the explosion of lithium batteries. The lithium molecules in the first lithium battery are extremely unstable, and it is easy to cause internal short circuit due to improper design or improper manufacture of lithium batteries by manufacturers who manufacture batteries. In addition, dust, water and temperature will affect the lithium battery and cause abnormal chemical changes. Therefore, the manufacturer must first place the lithium battery for a period of time before the lithium molecule is stabilized before leaving the factory. The influence of the second external factor, using an unidentified charging line, overcharging, dropping the lithium battery or long-term environment with high temperature and high humidity, will destroy the internal structure of the lithium battery. Once the lithium battery is found to be overheated and cannot be charged, When charging has not been full or deformed, there is a risk of explosion and should be stopped immediately to avoid the risk.

In view of the various risks arising from the use of the above lithium battery, the creator of the case created an explosion-proof mobile phone sleeve structure, which is composed of a multi-layer composite material to achieve anti-explosion, puncture resistance, high temperature resistance and combustion resistance, among which The multi-layer composite material is made of a bullet-proof composite material from the inner layer to the outer layer, which is used for preventing explosion of the battery and preventing the cutting of the chip, and the intermediate layer is a flame-resistant heat insulation layer, which is a flame-resistant material for isolating heat energy. The outermost layer is a leather material or a high-density cloth for preventing high-temperature leakage. With the above structure, the danger of explosion of a chemical battery in an electronic product can be effectively prevented.

The main purpose of this creation is to provide an explosion-proof mobile phone sleeve structure, which provides a multi-layer composite material, so that when the chemical battery in the electronic product is charged, the chemical battery can effectively block the explosion due to overcharging or over-discharging. The debris generated when the chemical battery explodes, so that the debris is covered by the explosion-proof mobile phone case, so as not to hurt the users and personnel of the electronic product or the surrounding affairs.

Another purpose of the present invention is to provide a flame-resistant structure in the explosion-proof mobile phone case structure. When the chemical battery in the electronic product explodes, the thermal energy emitted by the chemical battery can be effectively blocked and isolated from the outside, effectively Prevent people and things from burning the heat of the chemical battery to the outside.

In order to achieve the above object, the present invention discloses an explosion-proof mobile phone case structure, which comprises a puncture-proof layer, which has a first body, a second body and a third body, and the first a first crease line is formed on a side of the body and the second body, and a second crease line is formed on a side of the second body and the third body. The two side edges are provided with two first hem portions, and one fiber layer is connected to the puncture prevention layer.
