Abstract

The invention provides an anti-whiplash protector for automobiles, which includes a controller,a collision detection unit connected with the controller and arranged on the tail of the automobiles, an airbag arranged on the pillow. The airbag is connected with an inflator. The inflator is connected with the controller, and includes the vehicle speed detection unit connected with the controller, and an airbag regulating mechanism which can adjust airbag expansion strength arranged on the airbag and connected with the controller, corresponded to the detection signal of the vehicle speed detection unit. The anti-whiplash protector for automobiles and control method same and automobiles also provide a controller method for anti-whiplash protector and an automobile provided with the anti-whiplash protector. The Anti-whiplash protector for automobile can make the airbag swell and support the heads of passengers when the car hits the rear of another car, which avoids happening on whiplash injury. Meanwhile, the anti-whiplash protector for automobile further can adjust the swelling strength of the airbag, and improve the comfort.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile whiplash protection device. The invention also relates to a control method of the automobile anti-whiplash protection device, and an automobile equipped with the automobile anti-whiplash protection device. Background technique [0002] With the substantial increase in car ownership, various traffic accidents are also on the rise, especially rear-end collisions. In a rear-end collision, the vehicle in front of the rear-end is subjected to a forward acceleration, and the seat will push the occupant The torso is forward, but the occupant's head will lag due to inertia. This hysteresis makes the occupant's neck tilt back until it reaches the limit, and then the head is accelerated forward by the neck like a whip, which is what causes Whiplash effect of human neck injury. In order to reduce the damage caused to the occupants due to rear-end collisions, the existing...
