The embodiment of the disclosure provides a vehicle-mounted data recording device 10 which is used for being in communication connection with a vehicle-mounted system and recording operation data of the vehicle-mounted system. The in-vehicle data recording apparatus 10 includes a data storage disk 1, a waterproof case 2, and a protective case 3.

The data storage disk 1 is in communication connection with the vehicle-mounted system and stores the operation data of the vehicle-mounted system. The data storage disc 1 communicates with the on-board system via a data connection 4. The data connection line 4 may be a flexible cable.

The watertight housing 2 has a cavity for receiving a fixed data storage disc, preventing the data storage disc from being damaged by liquid ingress. In order to reduce vibration during driving of the vehicle and to prevent impact when the vehicle is damaged from affecting the on-vehicle data storage disk 1, a shock absorbing pad may be installed outside the waterproof case 2.

The protective casing 3 has a steel case 5 with openings at both ends, an upper cover 6 and a bottom cover 7 which are matched with the steel case to accommodate the waterproof case. The joints of the upper cover 6, the bottom cover 7 and the steel box body are all positioned on the inner wall of the steel box body 5.

The steel box 5 is formed by integral milling. The upper cover and the bottom cover are made of heat-insulating high polymer materials. The heat-insulating high polymer material meets the requirements that the melting point of the material is more than 1200 ℃, the performance does not change obviously at the high temperature of 1000-1100 ℃, the compressive strength is high, the processability is excellent, and the like. In one embodiment, the steel case 5 is integrally formed with the upper and

lower covers

6 and 7, respectively. Therefore, the gap that forms after making on-vehicle data logging device assemble is more tiny, can block more heat entering, tolerates higher temperature, and it is long when improving the temperature resistant.

Above-mentioned on-vehicle data recording device, the protecting sheathing adopts the steel box that has both ends open-ended, hold the upper cover of waterproof casing with the cooperation of steel box, the bottom, and the upper cover, the combination department of bottom and steel box is located the inner wall of steel box, the quantity in gap when not only having reduced the panel concatenation, and also avoided the gap to expose on the surface of protecting sheathing, the decline of heat-proof quality has been avoided, the holistic crashproof of on-vehicle data recording device has still been improved, the fire prevention burns, performance such as soaking is prevented.

In one embodiment, the contact area of the upper cover and the steel box body is within the range of 1/3-1/2 of the total contact area of the upper cover and the steel box body. The contact area of the bottom cover and the steel box body is 1/3-1/2 of the total contact area of the bottom cover and the steel box body. When the contact area of the upper cover and the bottom cover conforms to the range value, the overall performances of collision prevention, burning prevention, soaking prevention and the like of the vehicle-mounted data recording device can be better improved.

In one embodiment, a color developing paint layer is disposed on the protective housing. The color development coating layer can ensure that the vehicle-mounted data recording device can be found quickly after an accident occurs.
