Abstract
A breakaway passenger restraint system of a wheeled armored vehicle comprises a restraint seat (1), a fixing plate (2), an upper spring (3), a lower spring (4) and a shear pin (5); the method is characterized in that: the restraint seat (1) is fixed on the fixing plate (2) through the shearing pin (5), the fixing plate (2) is a connecting piece for connecting the whole restraint system and a vehicle body, the restraint seat (1) meets the requirements of stability and restraint of passengers under the common working condition, when the impact is larger than the tolerance limit of a human body, the shearing pin (5) is cut off, and the upper spring (3) and the lower spring (4) begin to play a role in damping and energy absorption to absorb impact energy. The separated passenger restraining system has the advantages of simple structure and convenient installation, and gives consideration to the comfort and safety of passengers.
Description
Technical Field
The invention relates to the technical field of wheeled armored vehicles, in particular to a breakaway passenger restraint system of a wheeled armored vehicle.
Background
Currently, many wheeled armored vehicles employ passenger seat restraint systems that are one-way energy absorbing and cushioning, but external impacts are transmitted through the vehicle body to the passenger's body from all directions. The existing passenger restraint system cannot solve the problems of multi-directional impact shock absorption and energy absorption, and a fully-suspended seat cannot meet the stability and comfort of passengers under normal working conditions.
Disclosure of Invention
The present invention is directed to overcoming the above-mentioned deficiencies of the background art and providing a breakaway occupant restraint system for a wheeled armored vehicle.
The invention relates to a breakaway passenger restraint system of a wheeled armored vehicle, which comprises a restraint seat 1, a fixing plate 2, an upper spring 3, a lower spring 4 and a shear pin 5, wherein the upper spring is fixed on the fixing plate; the restraint seat 1 is fixed on the fixing plate 2 through the shearing pin 5, the fixing plate 2 is a connecting piece for connecting the whole restraint system and a vehicle body, the restraint seat 1 meets the requirements of stability and restraint of passengers under the common working condition, when the impact is larger than the tolerance limit of a human body, the shearing pin 5 is cut off, the upper spring 3 and the lower spring 4 begin to play a role in shock absorption and energy absorption, and the impact energy is absorbed.
The invention realizes the switching between the normal road condition and the separated state through the shearing pin, has simple structure and convenient installation, and the upper spring and the lower spring play the roles of shock absorption and energy absorption, absorb the impact energy and give consideration to the comfort and the safety of passengers.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1-4, a breakaway occupant restraint system is illustrated. The invention comprises a restraint seat 1, a fixed plate 2, an upper spring 3, a lower spring 4 and a shear pin 5. The restraint seat 1 and the fixed plate 2 form a basic frame of the invention, the upper spring 3 and the lower spring 4 form a damping and energy absorbing mechanism of the invention, and the shear pin 5 is a disengaging mechanism of the invention. The restraint seat 1 is fixed on the fixing plate 2 through the shearing pin 5, the fixing plate 2 is a connecting piece for connecting the whole restraint system and a vehicle body, the restraint seat 1 meets the requirements of stability and restraint of passengers under the common working condition, when the impact is larger than the tolerance limit of a human body, the shearing pin 5 is cut off, the upper spring 3 and the lower spring 4 begin to play a role in shock absorption and energy absorption, and the impact energy is absorbed.
The separated passenger restraining system is simple in structure and convenient to install, and gives consideration to both comfort and safety of passengers.
