Abstract

The present invention relates to a novel vehicle bumper. The present invention is characterized in that an intelligent computer can convey signals to an electric control unit (ECU) via a sensor according to the speed of a vehicle when an obstacle at the distance of 10 meters from the front of the vehicle is detected by a radar detector arranged on the vehicle; the EPU is connected with an electric control switch of a direct current electric motor and the electric control switch (in positive rotation) can be automatically opened; the electric motor drives a transmission shaft to rotate; a screw rod driven by the transmission shaft can push an expansion shaft rod and a bumper away from the vehicle for 50 centimeters and then automatically stops, wherein the expansion shaft rod is connected with a nut and the bumper connected with the front of the expansion shaft is provided with an energy suction device; when the vehicle leaves away from the obstacle for 10 meters, the electric control unit opens the electric motor switch (in reverse rotation) and the expansion shaft drives the energy suction bumper to retract.

Description

Freely telescopic, buffering, energy absorbing vehicle bumper
Technical field
The present invention relates to a kind of freely telescopic, buffering, energy absorbing vehicle bumper.
Background technology
At present, aspect automobile collision preventing, generally just add crash barrier both at home and abroad at the Federal bumper place, buffering of adding behind guard rail and energy absorption device are also arranged, can not fundamentally solve the safety problem of passenger and car body, therefore, study a kind of safer, stretch out the car body front end fast, by also have behind buffering, the energy-absorbing one section safety distance anticollision device be of great value.
Summary of the invention
Can have after the object of the present invention is to provide a kind of quick-expansion, buffering, energy-absorbing to bump against one section safety distance anti-impact bumper.
Technical scheme of the present invention is: this safety device is by the radar detector and the sensor that are installed in before the car body, ECU (Electrical Control Unit) ECU 23 and be installed in rectify DC machine 20 on the shaped steel groove of automotive frame, telescopic shaft 5 and energy absorbing bumper combine, telescopic shaft comprises: the transmission shaft 15 that has helical wheel 16, double-threaded screw leading screw 13, double-threaded screw leading screw screw 12, spring fixed seat 10 and telescopic shaft 5, the energy-absorbing bumper assembly comprises: bumper/spoiler backplate 1, the energy absorbing tube 2 that can change, adapter plate 3, after radar detection has obstacle to the 10 meters distances far away in the place ahead, DC machine 20 can be through transmission shaft 15 with helical wheel 14, the bumper/spoiler that the mutual interlocks of helical wheel 16 drive double-threaded screw leading screw 13 turning handle telescopic shafts 5 and energy absorption device is installed is released preceding 50 centimeters of car body in 0.05 second time, behind the buffering by recoil spring 9 when car body and obstacle clash into mutually and the energy-absorbing of energy absorbing tube 2 30 centimeters safety distance can be arranged also, initiatively to construct out crash-resistant protection, make passenger and car body have absolute safety precaution with passivity safety.
Description of drawings
Figure A represents the energy absorbing tube that can change
Figure B represents the helical wheel of mutual interlock
Figure C represents recoil spring
Bumper/spoiler backplate 1, energy absorbing tube 2, adapter plate 3, check screw 4, telescopic shaft 5, automobile front cross rail 6, automotive frame 7, spring check screw 8, recoil spring 9, spring fixed seat 10, check screw 11, the screw 12 of double-threaded screw leading screw, double-threaded screw leading screw 13, helical wheel 14, transmission shaft 15, helical wheel 16, belt pulley 17, adapter plate 18, fixedly feed screw nut 19, DC machine 20, fixed beam 21, the automotive frame shaped steel 22 of rectifying, ECU (Electrical Control Unit) ECU 23, electric machine support 24, transmission shaft permanent seat 25
The specific embodiment
Referring to accompanying drawing, shown in embodiment wherein, the anti-collision device system comprises the bumper/spoiler that has energy absorbing tube 2, two telescopic shafts 5, the telescopic shaft assembly comprises: two recoil springs 9, two spring fixed seats 10, two double-threaded screw leading screws 13, double-threaded screw leading screw main part comprises: two double-threaded screw screws 12, helical wheel 14, helical wheel 16, DC machine 20, DC machine comprises: belt pulley 17, electric machine support 24, ECU (Electrical Control Unit) ECU 23.
When the radar detector before being installed in car body detects 10 meters in car body the place ahead and far obstacle is arranged, sensor can calculate the time that car body and obstacle bump against according to the speed of car speed, signal is passed to ECU (Electrical Control Unit) ECU 23, ECU (Electrical Control Unit) ECU 23 can open DC machine 20 positive turn-off passes automatically, DC machine 20 makes helical wheel 14 through transmission shaft 15, helical wheel 16 mutual interlocks drive double-threaded screw leading screw 13 and rotate, through double-threaded screw feed screw nut 12 telescopic shaft 5 is stopped bumper/spoiler that telescopic shaft the place ahead is equipped with energy absorption device is released the preceding 50 centimeters distances of car body in 0.05 second time after automatically with being connected, after making car body and obstacle bump 30 centimeters safety distance is arranged, the energy-absorbing that the recoil spring of impact through telescopic shaft 5 back cushioned and added the bumper/spoiler of energy absorption device sponges huge impact, after car body and obstacle leave 10 meters distances far away, ECU (Electrical Control Unit) ECU 23 can open DC machine 20 reversal switches, DC machine 20 drives transmission shaft 15, drives telescopic shaft 5 and energy-absorbing bumper withdrawal through double-threaded screw leading screw 13.
