Description

Automobile active avoidance multi-function occupant life safety protection system

Technical field

The invention relates to the field of automobile safety and lifesaving manufacturing, and particularly relates to a vehicle active avoidance multi-function occupant life safety protection system.

Background technique

In the prior art automobile manufacturing industry, the safety protection of the occupants in the vehicle mainly relies on the measures such as the device bumper, the air shackles and the seat belts. However, since the existing safety protection measures are passively designed, the accidents are When it occurs, it is easy to cause the tragic result of the subjective human error caused by the occupant itself, such as not wearing a seat belt, and not setting a safety air valve. In addition, if the car is subjected to different angles including front, back and side When the vehicle is in a different direction, the safety measures of the prior art cannot fully protect the occupants in the vehicle. Moreover, if the car falls into the water and falls into the water, the prior art safety protection measures are basically powerless.

Summary of the invention

SUMMARY OF THE INVENTION An object of the present invention is to overcome the deficiencies of the prior art and to provide a vehicle active avoidance type multifunctional occupant life safety protection system capable of greatly improving the life safety support capability of an internal occupant in the event of an automobile accident.

The automobile active avoidance multifunctional occupant life safety protection system of the invention adopts a new technical principle of active avoidance and long-term inertia reduction shock absorption, and the specific technical solution thereof is to completely replace the existing automobile cab from the automobile. The car body is separated into a separable cab portion, and the remaining part is a car chassis. The connection between the control system, the mechanical system and the electrical equipment between the separable cab and the car chassis is conventional. The utility model can be divided into a mechanical connection and an electromagnetic connection mode, and the coupling of the coupling members can be manually controlled or automatically controlled, and a double arm shock absorbing eliminator is added at the rear of the automobile chassis. The two-armed shock absorber avoidance device includes a horizontally positioned shock absorption avoidance arm, a vertically positioned shock absorber arm, a hydraulic lift stabilizer bar, an adjustable wide distance support bar, a hydraulic lift avoidance column, and a telescopic telescopic shaft. Wherein, the sleeve type telescopic shaft is installed at the center of the top of the splittable driving compartment, and the horizontal positioning shock absorbing arm is installed on both sides thereof, and the adjustable wide distance support rod is installed on the rear seat of the automobile chassis, The two ends of the adjustable wide-distance support rod are connected with the horizontally positioned shock-absorbing and avoiding arm through the vertical positioning shock-absorbing arm, and the hydraulic lifting in the oblique direction is also installed between the vertical positioning shock-absorbing arm and the horizontally-positioned shock-absorbing and avoiding arm. The stabilizing rod has a hydraulic lifting and escaping column in the rear seat of the automobile chassis, which is connected with the adjustable wide-distance support rod above, and has a hydraulic adjusting mechanism inside the automobile chassis, which is connected with the hydraulic lifting and avoiding column to Hydraulic power is provided by actions such as the lifting and lowering of the arm damper.

The bottom of the separable driving compartment of the present invention can also be equipped with an inflatable cushion as needed. In an emergency, the inflation valve automatically opens the inflation, and can be added as needed in the outer rear portion of the detachable driving compartment. A simple DC auger to allow self-propelled capacity in the interchangeable cab.

The active avoidance multifunctional occupant life safety protection system of the vehicle can separate the detachable driving compartment and the chassis where the occupant is located according to the magnitude and direction of the impact force, and can make the corresponding rotation of the detachable driving compartment, Lifting and other avoidance protection actions to protect the safety of the occupants, the advantages are as follows: 1. The driver's cab is lifted off the chassis, which can effectively avoid direct collision and deformation of the chassis to the human body; The chassis can effectively avoid being burned. 3. The driving room makes the inertia reduction shock absorption and avoidance according to the impact force, which can prevent the damage caused by the strong impact; 4, the double arm shock absorber and the rotation of the driving room, Avoid the damage caused by multi-directional impact; 5. Because the driver's cab can be completely separated from the chassis and its cushioning such as the inflatable cushion, it can greatly reduce or avoid the damage caused by the fall of the height difference to the occupant; After the driver's cab is separated from the chassis, it can float to the surface by itself, and can rely on the configured DC auger to drive in the water, which can effectively save the water. member.

detailed description

As shown in FIG. 1, FIG. 2 and FIG. 3, the vehicle active avoidance multifunctional occupant life safety protection system of the present invention comprises two parts, a splittable driving compartment 1 and a vehicle chassis 2, on the rear surface of the automobile chassis 2. A double-armed shock absorber is included, and the double-armed shock absorber includes a horizontally positioned shock absorber avoidance arm 3, a vertically positioned shock absorber arm 4, a hydraulic lift stabilizer bar 5, and an adjustable wide-width support bar 6 , hydraulic lifting avoidance column 7 and telescopic telescopic shaft 9. Wherein, the telescopic telescopic shaft 9 is installed at the center of the top of the detachable cab 1 , and horizontally positioned evasive avoidance arms 3 are mounted on both sides thereof, and an adjustable wide-distance support rod is installed on the rear seat of the automobile chassis 2 6. The two ends of the adjustable wide-distance support rod 6 are connected to the horizontally-positioned absorbing escape arm 3 through the vertical positioning damper arm 4, and the hydraulic lifting evasion column 7 is provided in the rear seat of the automobile chassis 2, The connection between the widening support rod 6 and the hydraulic lifting and avoiding column 7 is horizontally rotatable, that is, the adjustable wide distance support rod 6 and its supporting portion can be horizontally rotated around the hydraulic lifting and avoiding column 7 in addition, A hydraulic lifting and lowering stabilizer bar 5 is disposed between the vertically positioned damper arm 4 and the horizontally positioned damper avoiding arm 3, and a hydraulic adjusting mechanism is disposed inside the vehicle chassis 2, and is connected to the hydraulic lifting and evasing column 7. Hydraulic power is provided by the action of lifting and lowering the double-armed shock absorber, and in an emergency, the telescopic shaft 9 can be detached from the double-armed shock absorber to realize the splittable driving compartment 1 Complete separation from the chassis 2 of the car .
