[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figure 1-3 As shown, a battery box with a fire protection module comprises a battery box 1 and a fire protection module 2 located on the surface of the battery box 1, wherein the battery box 1 and the fire protection module 2 are slidably matched, first contacts 3 connected to a fire detection device are provided on both sides of the surface of the battery box 1, a fire extinguishing agent 2.1 is provided inside the fire protection module 2, an electric ignition head 2.2 is provided inside the fire extinguishing agent 2.1, and the electric ignition head 2.2 is connected to second contacts 4 on both sides of the surface of the fire protection module 2 through a starting harness, the first contact 3 and the second contact 4 cooperate, and the nozzle 2.3 of the fire protection module 2 cooperates with the through hole 1.1 on the surface of the battery box 1.

[0021] Preferably, the fire detection device includes a detection sensor, the output end of the detection sensor is connected to the input end of the controller, and the output end of the controller is connected to the control end of the power module of the circuit where the first contact 3 is located. In this embodiment, when there is a fire, overheating, etc. in the battery box 1, the detection sensor detects the high temperature environment and sends a signal to the controller, thereby controlling the power module of the circuit where the first contact 3 is located to work, so that the first contact 3 passes the current, and the second contact 4 connected to the first contact 3 also passes the current, and finally the electric ignition head 2.2 passes the current through the starting harness to perform the ignition process, and the fire extinguishing agent 2.1 is ignited through the process of electric ignition to produce fire extinguishing substances; in this embodiment, the controller can use a 51 single-chip microcomputer, model 80C51 single-chip microcomputer, or use an STM32 microprocessor, model STM32F103; the first contact 3 and the second contact 4 are metal sheet structures.

[0022] Preferably, the detection sensor is a temperature sensor and / or a smoke sensor.

[0023] Preferably, a mounting plate 1.2 is fixedly provided on the top or bottom of the battery box 1, a guide groove 1.3 is provided on the surface of the mounting plate 1.2, a guide rail 2.4 is provided on the side where the nozzle 2.3 of the fire module 2 is located, the guide groove 1.3 and the guide rail 2.4 are slidably matched, and the first contact 3 on the surface of the battery box 1 is provided in the area where the mounting plate 1.2 is located. With such a design, the fire module 2 can be quickly installed on the top of the battery box 1 through the sliding matching process of the guide groove 1.3 and the guide rail 2.4, and the corresponding number of fire modules 2 can be quickly installed according to actual needs.

[0024] Preferably, the through hole 1.1 on the surface of the battery box 1 is opened in the area where the mounting plate 1.2 is located, and the through hole 1.1 is provided with a protective plate 1.4 that matches with it. By providing the protective plate 1.4, the through hole 1.1 without the fire protection module 2 installed can be protected to prevent dust from entering the battery box 1 through the through hole 1.1.

[0025] Preferably, the fire extinguishing agent 2.1 is also wrapped with a heat shrink bag 2.5. The heat shrink bag 2.5 can wrap and limit the fire extinguishing agent 2.1, and also enhance the sealing performance, preventing external moisture from entering the fire module box through the gap and causing moisture absorption.

[0026] Preferably, the fire extinguishing agent 2.1 is aerosol generating agent powder.

[0027] Preferably, the outer contours of the mounting plate 1.2 and the fire fighting module 2 are both rectangular plate structures. The mounting plate 1.2 and the fire fighting module 2 with rectangular plate structures are relatively flat, which can greatly reduce the space occupied and improve the space utilization.

[0029] The working principle of this embodiment is as follows:

[0030] When in use, the corresponding protective plate 1.4 is removed according to the number of batteries in the battery box 1. Through the sliding fit of the guide groove 1.3 and the guide rail 2.4, the corresponding number of fire protection modules 2 can be quickly installed on the top of the battery box 1, and the first contact 3 and the second contact 4 are aligned, and the sealing groove 1.5 and the sealing strip 2.6 are also aligned; thereby completing the entire installation process.

[0031] When a fire or overheating occurs in the battery box 1, the detection sensor of the fire detection device detects the high temperature environment and sends a signal to the controller, thereby controlling the power module of the circuit where the first contact 3 is located to operate, so that current passes through the first contact 3, and the second contact 4 connected to the first contact 3 also passes through current, and finally the electric ignition head 2.2 passes current through the starting wiring harness to perform the ignition process. Through the above-mentioned electric ignition process, the fire extinguishing agent 2.1 is ignited to produce fire extinguishing material, which is sprayed out along the nozzle 2.3 and enters the battery box 1 through the through hole 1.1 to perform a fire extinguishing process inside.
