Damping device capable of protecting passengers and reducing vehicle rear-end collision impact force

Abstract

The invention discloses a damping device capable of protecting passengers and reducing vehicle rear-end collision impact force. The device comprises a car body and a passenger protection device located in the car body. The device comprises a cab and a first sliding groove located in the lower side of the cab. The first sliding groove and the cab are arranged in a communicating mode through a through groove. A first sliding block is connected into the first sliding groove in a sliding manner; the device can automatically start the rear side anti-collision device after the distance between the vehicle and the front vehicle reaches a certain degree; the phenomenon of rear-end collision of the rear vehicle due to untimely braking is avoided; and meanwhile, when the rear vehicle cannot brake intime to cause rear-end collision, the buffer device on the front side is automatically started, the damage degree of the rear-end collision with the front vehicle is avoided or reduced, and meanwhile, when the rear vehicle or the front vehicle collides, the passenger protection device can be started so that the safety of passengers is protected to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted devices, in particular to a shock-absorbing device capable of protecting passengers and reducing the impact force of a vehicle rear-end collision. Background technique [0002] Vehicles often encounter heavy snow or fog during driving. If a certain safe distance or prescribed speed is not guaranteed, it is very easy to cause the front side to brake the car while the rear car cannot brake the car, resulting in a series of rear-end collisions. Simultaneously because rear car hits suddenly for this vehicle, the driver of this car and front car is not prepared in heart, very easily causes the injury on the body under the action of inertia. Contents of the invention [0003] In view of the deficiencies of the above-mentioned technologies, the present invention proposes a shock-absorbing device capable of protecting passengers and reducing the impact force of a vehicle rear-end collision, whic...

Problems solved by technology

[0002] Vehicles often encounter heavy snow or fog during driving. If a certain safe distance or prescribed speed is not guaranteed, it is very easy to cause the front side to brake the car while the rear car cannot brake the car, resulting in a series of rear-end collisions. At the same time, due to the suddenness of the impact of the rear vehicle on the vehicle, the drivers and passengers of the vehicle and the vehicle in front are not prepared, and it is very easy to cause physical damage under the action of inertia.
