The specific embodiment
Embodiment one:
As shown in Figure 1, 2, present embodiment comprises elastic compression device and reset attachment, it is characterized in that elastic compression device comprises push rod 1, compression spring 3, spring socket sleeve 4 and clamp 5, push rod 1 is provided with laciniation 2, laciniation 2 outer compression spring 3 and the spring socket sleeves 4 of being with, the clamp 5 that is used to block the sawtooth facing is equipped with in spring socket sleeve 4 ends, and clamp 5 symmetries are installed in the end of spring socket sleeve 4, on the axle of clamp 5 torsion spring 6 is housed; Reset attachment comprises reset screw mandrel 9 and reduction nut 10, and reduction nut 10 is contained in the end of the screw mandrel 9 that resets.
The push rod 1 of the elastic compression device of this mechanical spring formula force absorbing energy storage anti-colliding safety device can be fixed on the front and back bumper/spoiler A of automobile, being enclosed within the outer spring socket sleeve 4 of push rod laciniation and compression spring is fixed on the automotive frame cross bar B, (as shown by arrows) push rod 1 moves vertically when Federal bumper A is subjected to external impacts, compression spring 3 is in the compressed while, the sloping platform face of laciniation 2 is pushed clamp 5 open, this moment, length of spring compressed power increased, external force absorbs and storage colliding, and forms resistance power external force is weakened.When external force equated with resistance power, clamp 5 held out against the vertical surface of laciniation 2 under the effect of torsion spring 6, and compression spring 3 must not be rebounded, and so just came colliding the external force absorption, converted the power of compression spring to, had played the effect of cushion bumper.Reset attachment is installed between Federal bumper A and the crossbeam cross bar B, after automobile is impacted, the reset process of bumper/spoiler A is as follows: earlier reduction nut 10 is tightened on silk 9 bars that reset, by the window on the push rod adjustment seat 8, take off torsion spring 6 then, clamp 5 breaks away from the vertical surface of laciniation 2, slowly loosen reduction nut 10 again, bumper/spoiler A will restore to the original state, and load onto torsion spring 6 this moment, and this device recovers original state again.
This apparatus structure is simple, applicability is strong.
Embodiment two:
As shown in Figure 3, present embodiment comprises spring pneumatic accumulator 12, spring reset ram cylinder 16, hydraulic oil pipe 17, check valve 18 and control cock 19, it is characterized in that spring reset ram cylinder 16 is connected with spring pneumatic accumulator 12 oil inlets with check valve 18 by hydraulic oil pipe 17, the oil outlet of spring pneumatic accumulator 12 forms the loop through bypass hydraulic oil pipe 20 and control cock 19 with spring reset ram cylinder 16 again.Control cock 19 can be normally closed bi-bit bi-pass control cock.Return piston 26 front ends of spring reset ram cylinder 16 are equipped with retracing spring 27; Be provided with pressure gas, spring 13, piston 14 and oil cylinder 15 in the cylinder body of spring pneumatic accumulator 12, the front end compressed air suits of piston 14 also is equipped with spring 13.
Spring reset ram cylinder 16 can be arranged on the front and back bumper/spoiler A of automobile, and a plurality of spring reset ram cylinders 16 can a shared spring pneumatic accumulator 12.
