1 is a perspective view showing a disaster prevention memory for an automobile black box according to the present invention, wherein upper and lower cases 11 and 12 made of high-strength metal are coupled to the fixing bolt 30, and the upper case 11 and the lower case 12 are shown in FIG. ), A gasket 20 is provided, and data input / output terminals 11a and a power supply terminal 12a are formed on one side of the upper and lower cases 11 and 12, respectively.

The upper and lower cases 11 and 12 are formed by performing surface processing after single-casting or casting a metal having a melting point equal to or higher than the tensile strength of stainless steel, and having a high tensile strength of 100 tons and a melting point of 1500 ° C. It has high heat resistance. In addition, an ultrasonic wave antenna and an AM wave antenna for transmitting a position signal informing its position are provided on one side of the upper and lower cases 11 and 12.

Meanwhile, as shown in FIGS. 2 and 3, the upper and lower cases 11 and 12 have an interface portion 61, an ultrasonic wave / AM wave generator 62 and 63 and a memory 64 that generate position signals. The mounting groove 13 to which the metal case 40 with the circuit board 60 made of the power supply unit 65 is mounted is formed, and the metal case 40 has a circuit when the upper and lower cases 11 and 12 are damaged. It is used as a preliminary protection device to protect the board, and it also functions to stably operate the circuit by blocking the emission of electromagnetic waves generated from inside and blocking the electromagnetic waves and noise introduced from the outside.

In addition, the outer surface of the metal case 40 is coated with a refractory carbon 70, the metal case 40 is coated with a refractory carbon 70 is wrapped in a glass fiber 50, upper and lower cases (11, 12) It is mounted to the mounting groove 13 formed in. Therefore, the fireproof carbon 70 substantially blocks heat conduction transferred to the circuit board 60 through the upper and lower cases 11 and 12 and the glass fibers 50 having heat resistance, and the glass fiber 50 is the upper and lower cases ( 11 and 12 to protect the circuit board 60 by forming a buffer layer that minimizes the heat conduction and absorbs the shock.

In addition, a connection terminal 41 is formed at one side of the metal case 40, and the connection terminal 41 is a data input / output terminal 11a or a power supply terminal 12a formed or installed in the upper and lower cases 11 and 12. And the ultrasonic antenna 11b and the AM wave antenna 12b are connected to the circuit board 60 embedded in the metal case 40 through the wire 100.
