Vehicle-mounted data recorder with strong impact resistance

Abstract

The invention discloses a strong impact resistance type vehicle-mounted data recorder which comprises a spherical storage chamber and a protective shell, the spherical storage chamber is of a multi-layer shell structure, gaps between adjacent shells are equal, the gaps between the adjacent shells are filled with filler, the filler internally comprises a plurality of hollow structures, the hollow structures are arranged in the spherical storage chamber, and the protective shell is arranged in the spherical storage chamber. A storage card groove is formed in the outer wall of the spherical storage cavity, a TF storage assembly is installed in the storage card groove, the TF storage assembly is connected with a TF card external connection wire extending to the outside of the protection shell, the spherical storage cavity is of a multi-layer structure and is filled with filler of a special structure, and the black box is prevented from being damaged in the collision process; when the vehicle-mounted data recorder is impacted, information in the vehicle-mounted data recorder can be better and comprehensively protected, and the anti-explosion performance and the impact resistance of the spherical storage cavity are improved.

Description

technical field [0001] The invention relates to a vehicle-mounted data recorder with strong impact resistance. Background technique [0002] Data recorders are commonly known as "black boxes". Under the mandatory requirements of relevant regulations in various countries in the world, data recorders must be installed on aircraft and vehicles. The main purpose is to analyze the cause of accidents. [0003] When a car or a plane crashes unexpectedly, the accidental occurrence of the vehicle-mounted recorder can be used. The vehicle-mounted recorder provides great convenience for people's driving life. However, the vehicle-mounted recorder in the prior art still has certain deficiencies. The current mainstream black box has a volume of about 300×200×150mm3 and a weight of about 20kg, which shows that it is large and heavy. The casing is usually made of 0.64cm thick stainless steel or titanium alloy, and a 2.54cm thick high temperature insulator is placed in the casing. The inne...

[0003] When a car or an airplane collides unexpectedly, the accidental occurrence of the vehicle-mounted recorder can be used. The vehicle-mounted recorder provides great convenience for people's driving life. However, the vehicle-mounted recorder in the prior art still has certain deficiencies. The current mainstream black box has a volume of about 300×200×150mm3 and a weight of about 20kg, which shows that it is large and heavy

The casing is usually made of 0.64cm thick stainless steel or titanium alloy, and a 2.54cm thick high-temperature insulator is placed in the casing. The innermost recording unit CSMU (Crash Survival Memory Unit) uses three layers of materials to isolate the memory chip that stores digital information. , and save it, even with such layers of protection, the storage part is easily damaged due to a large impact, the black box is also easily damaged during the collision, and the storage device in the on-board data recorder cannot be obtained when the impact Comprehensive protection, therefore, a strong impact-resistant vehicle data recorder came into being
