The rear seat 100 is mounted on an upper slide rail 101, the upper slide rail 101 is slidably disposed on a lower slide rail 102, and the upper slide rail 101 can be locked on the lower slide rail 102. When a rear-end collision happens, the unlocking mechanism releases the locking of the upper slide rail 101, and the releasing mechanism pushes the upper slide rail 101 to slide forwards along the lower slide rail 102.
According to the rear-row passenger rear-end collision protection system for the vehicle, when a rear-end collision accident happens, the collision detector 2 transmits a collision signal to the collision controller 1 through detection, the collision controller 1 decides to send a release signal to the release mechanism in the release device 3, the release mechanism releases after receiving the release signal, the unlocking mechanism unlocks the upper slide rail 101, the release mechanism pushes the upper slide rail 101 to slide forwards along the lower slide rail 102, the distance between the rear-row passenger and the tail of the vehicle is further increased, the injury of the rear-row passenger in the rear-end collision process is reduced, and the safety of the passenger is improved.
The release mechanism provided by the present embodiment includes a base 31 and a push rod 32, the push rod 32 is telescopically installed in the base 31 along the front-back direction, and the push rod 32 can push the upper slide rail 101 to slide along the lower slide rail 102. After receiving the release signal, the push rod 32 moves forward, the unlocking mechanism unlocks the upper slide rail 101, and the push rod 32 pushes the upper slide rail 101 to slide forward along the lower slide rail 102.
It should be noted that, in the present embodiment, one release device 3 is provided on each rear seat 100. Of course, in other embodiments, two releasing devices 3 may be disposed on each rear seat 100, wherein one releasing device 3 is used for pushing the upper sliding rail 101 on the left side of the rear seat 100 to slide, and the other releasing device 3 is used for pushing the upper sliding rail 101 on the right side of the rear seat 100 to slide.
Specifically, in the present embodiment, the collision detector 2 is mounted on the rear of the vehicle in order to accurately and quickly detect whether a rear-end collision has occurred.
Alternatively, the collision detector 2 is a collision intensity sensor. The force generated during collision is detected by the collision strength sensor, the numerical value of the force is sent to the collision controller 1, if the detected numerical value of the force exceeds a preset value, the rear-end collision accident is judged to occur, and the collision controller 1 sends a release signal to the release mechanism.
Alternatively, the base 31 is fixedly mounted at the rear end of the lower slide rail 102. Of course, in other embodiments, the base 31 may also be fixedly mounted on the floor of the vehicle through a mounting bracket, which is not limited herein. Optionally, the base 31 is cylindrical.
