Description

TECHNICAL FIELD

[0002] In the long development process of the automobile industry, with the continuous innovation and progress of science and technology, the performance and safety of the automobile have been comprehensively improved. Among them, the passive safety performance of the automobile, as a key element to protect the life safety of the passengers, has made great breakthroughs and leaps. The passive safety system of the automobile is a complex and precise whole, which covers many important components. The automobile seat, safety belt and airbag are the core elements. Although the existing passive safety device can effectively reduce the injury degree of the passengers in the accident to a certain extent, in the actual crash scene, the injury situation of each part of the passenger's body still has many complexities and uncertainties. Especially, the chest, as the part where the important organs of the human body are located, has a complex structure and is relatively fragile, and is easily seriously injured in a crash accident, such as rib fracture, lung injury, etc. These injuries often pose a great threat to the life and health of the passengers. Therefore, it is of great practical significance and urgency to develop a dummy chest crash pressure detection device.

[0003] As for the existing dummy chest crash pressure detection device, the device adopts an integrated skeleton structure. When part of the bone plate is damaged in the long-term test and use process, the damaged bone plate cannot be replaced alone, which increases the use cost and causes waste of resources. Moreover, the pressure detection capability of the device for different simulated chest positions is limited. The pressure sensor is not convenient to disassemble and assemble, which affects the maintenance efficiency of the device and reduces the overall use efficiency of the device. The structure of the dummy chest crash pressure detection device is relatively fixed, and it is difficult to externally connect shoulder and neck detection components and lower limb detection components of different sizes according to actual needs. When it is necessary to expand the dummy model of different specifications or different detection items, the existing device cannot be flexibly adapted, which greatly limits its application range and universality, and cannot meet the diversified detection needs.
