Seat device for passenger safety protection in passenger car rollover accident

Abstract

The invention discloses a seat device for protecting the safety of a passenger in a bus rollover accident. The seat device comprises a frame, a first telescopic rod, a spring, a crank, a food stand, a second telescopic rod and a locking device. An upper rod of the second telescopic rod is movably connected with the other end of the frame, a lower end of the second telescopic rod is fixedly connected with a base plate of a compartment, and the upper rod is movably inserted into the lower rod in a connected mode. The locking device is arranged on the lower rod. The crank is fixedly connected with one end of the first telescopic rod. One end, fixedly connected with the crank, of the first telescopic rod is movably connected with the middle of the foot stand, one end of the spring is connected with the middle of the crank, and the other end of the spring is connected with a transverse rod arranged at the upper end of the foot stand. The locking device comprises a hinge pin, a servo motor and a control system. A gyroscope and an acceleration sensor of the control system are respectively connected with an STM32F407 electronic control unit. One end of the hinge pin is connected with the servo motor, and the other end of the hinge pin is inserted into the upper rod and the lower rod in a telescopic mode. The seat device can effectively avoid second-time collision in the bus rollover accident, and the passenger protection capacity of a bus is greatly improved.

Description

technical field [0001] The invention relates to a passenger car passenger safety protection device, in particular to a seat device for protecting passenger safety in a passenger car rollover accident. Background technique [0002] The harm of the rollover accident of the passenger car is very great, and it is easy to cause the bad consequences of mass death and injury of the crew. Even if the passenger car body meets the relevant crashworthiness standards, it is still difficult to ensure that the occupants are effectively protected in the rollover accident. The reason is that the body structure will be greatly deformed during the rollover impact. The probability of secondary impact on the side wall is very high. Therefore, this kind of safety seat device that can be actively tilted is designed so that the vehicle seat tilts toward the aisle side when the vehicle rolls over, effectively increasing the distance between the occupant and the side wall, and avoiding the contact ...
