Abstract

The invention provides a flame-retardant flash memory device, which includes a first housing, a first circuit board and a first transmission interface. The first circuit board includes a controller and multiple flash memory assemblies. The first circuit board is arranged in the first housing and is wrapped in a first fireproof material. The first transmission interface is arranged outside the first housing. A circuit connecting wire is connected between the first circuit board and the first transmission interface. The flash memory assemblies are accommodated in the fireproof housing. If the flash memory device is placed in a scene of fire, the fireproof housing can effectively isolate high temperature to prevent the flash memory assemblies from being burnt out.

Description

technical field [0001] The invention relates to a flame-resistant flash memory device, in particular to a flash memory device which can prevent flash memory components from being burned. Background technique [0002] Nowadays, digital video recorders (digital video recorders, DVRs) are mostly installed on many buses. The digital video recorder can not only monitor the condition of passengers in the bus, but also can use the video recording function of the digital video recorder to record images in case of emergencies. Afterwards, the images recorded by the digital video recorder will be used as evidence to clarify responsibility. [0003] Digital video recorders usually use a flash memory device as a storage medium for recording images. figure 1 It is a circuit structure diagram of an existing flash memory device. Such as figure 1 As shown, the flash memory device 100 can be set in a digital video recorder, which includes a casing 10 . The shell 10 can be a metal shell....
