The utility model is owing to link to each other by movable component between forward and backward bumper/spoiler and the chassis, movable component is with one group of spring outward, movable component and spring are located in vertical girder steel inner chamber of car chassis, when bump takes place when, a plurality of springs can compress in succession backward, so just produce a bigger bounce forward, and buffering by a plurality of springs, prolonged the collision time of car body and car body, reduced impact, have bigger holding capacity and buffering effect, significantly reduced the injury that bump brings for automobile and chaufeur, reach preferable protective effect; Because movable component and spring are located at the inside of vehicle frame, good looking appearance, assembling is easily; Owing to added movable component, make the left and right beam of car chassis become two, also improved the ability that anti-side is hit.
Below in conjunction with concrete structure and the principle of work of accompanying drawing detailed description according to the anti-collision device for automobile that the utility model proposes.
Fig. 1 is provided in a side of the structural representation of car chassis vertical girder steel in-to-in mandrel and sliding sleeve;
Fig. 2 is the part sectional view that has the car chassis front portion of anti-collision device for automobile;
Fig. 3 is the part sectional view that has the car chassis rear portion of anti-collision device for automobile;
Fig. 4 is the A-A cutaway view of Fig. 2.
Present car chassis all is " order " font, car chassis of the present utility model is the brace panel 8 with the increase by of two vertical girder steels, 3 middle parts with the chassis integrally casting moulding of original " order " font, be respectively equipped with one group of elastic force movable component that can play buffer action in the front and back section inner chamber 31,32 of two vertical girder steels 3, movable component drives forward and backward bumper/spoiler 1,11 and can inwardly or outwards stretch.
As Fig. 1,2, shown in 4, front bumper 1 and movable component are fixing by mandrel 4 serial connections, first sliding sleeve 2 and four second sliding sleeves 6 are enclosed within outside the mandrel in the mode that is connected in series successively, first sliding sleeve, 2 external diameters are provided with bulge loop 21, second sliding sleeve, 6 external diameters are provided with bulge loop 61, outside four second sliding sleeves 6, be with four recoil springs 5, mandrel 4, sliding sleeve 2 and 6, recoil spring 5 all is located in the anterior inner chamber of vertical girder steel of car chassis, the longitudinal travel of the bulge loop 61 outside (to the directions of front bumper) of four second sliding sleeves is spacing by four boss 7 in the anterior inner chamber of vertical girder steel, recoil spring 5 one ends limit its axial shift position by bulge loop 61, the other end is spacing by the boss 7 in the anterior inner chamber of vertical girder steel, and a spacing end of first recoil spring is the bulge loop 21 by first sliding sleeve, the other end is to be antetheca restrictions by vertical girder steel by boss 7, the first sliding sleeves 2 outside displacements in the anterior inner chamber of vertical girder steel; Between the bulge loop 61 of mandrel 4 and the 4th second sliding sleeve 6 and the anterior inner chamber of vertical girder steel a space is arranged, a compression spring 9 wherein is housed, that is to say that compression spring 9 inside do not have mandrel; Vertically the front portion of girder steel 3 by have four boss 7 "
" the vertical girder steel base plate of shape forms with the vertical relative grafting of girder steel cover plate, cover plate can be opened when inner body need be safeguarded or change.Car chassis laterally be provided with embedded with safety thick stick 10, more increase its crashworthiness.
When front bumper was subjected to the collision of external force, first sliding sleeve and mandrel moved inward immediately, and the bulge loop of first sliding sleeve makes the recoil spring compression, plays buffer action; The bulge loop of four second sliding sleeves makes three recoil spring compressions immediately, and the effect of buffering is further played in a compression spring compression.There are mandrel and sliding sleeve in recoil spring inside, and does not have mandrel and sliding sleeve in the middle of the compression spring, and generally speaking, 5 springs can compress 1-15 centimetre in succession backward, so just produce a bounce forward.The front bumper that is impacted, mandrel and first sliding sleeve become first stress point, and by the buffering of 5 springs, collision time prolongs, and has reduced impact greatly; The embedded with safety thick stick is as second stress point, and so just having formed the outside is the movable component that alleviates impact, and inside is again the double insurance system of the bumper/spoiler of a safety.
Equally, as shown in Figure 3, rear bumper 11 and movable component are fixing by mandrel 41 serial connections, first sliding sleeve 2 and one second sliding sleeve 6 are enclosed within outside the mandrel 41 successively in the mode that is connected in series, first sliding sleeve, 2 external diameters are provided with bulge loop 21, second sliding sleeve, 6 external diameters are provided with bulge loop 61, outside two second sliding sleeves 6, be with two recoil springs 5, mandrel 41, sliding sleeve 2 and 6, recoil spring 5 all is located in vertical girder steel rear portion inner chamber of car chassis, the longitudinal travel of the bulge loop 61 outside (to the directions of rear bumper) of two second sliding sleeves is spacing by two boss 7 in the inner chamber of vertical girder steel rear portion, recoil spring 5 one ends limit its axial shift position by bulge loop 61, the other end is spacing by the boss 7 in the inner chamber of vertical girder steel rear portion, and a spacing end of first recoil spring is the bulge loop 21 by first sliding sleeve, the other end is to be by the restriction of the rear wall of vertical girder steel by the 2 outside displacements of 7, the first sliding sleeves of the boss in the inner chamber of vertical girder steel rear portion; Between the bulge loop 61 of mandrel 4 and second second sliding sleeve 6 and the vertical girder steel rear portion inner chamber space is arranged, a compression spring 9 wherein is housed; Vertically the rear portion of girder steel 3 by have two boss 7 "
" the vertical girder steel base plate of shape forms with the vertical relative grafting of girder steel cover plate, cover plate can be opened when inner body need be safeguarded or change.
When rear bumper is subjected to the collision of external force, first sliding sleeve and mandrel move inward immediately, and the bulge loop of first sliding sleeve makes the recoil spring compression, plays buffer action, the bulge loop of second sliding sleeve makes a recoil spring compression, a compression spring compression, further plays the effect of buffering.
The existing automobile that is 1300Kg with a quality per hour travels 72 kilometers the time, bumps against with another object, and the collision time is to be calculated as example in 2 seconds:
Initial velocity v
0=72 kilometers/hour=72000 meters/3600 seconds=20 meter per seconds
End speed v
t=0
Collision time t=2 second
Time a=(v
t-v
0)/t=(0-20)/2=-10 meter per second
2
Impact F=ma=1300kg * 10 meter per seconds
2=13000 newton
Then the impact of Chan Shenging is 13000 newton, and as by aforementioned calculation, two groups of movable components and spring are located in left and right vertical girder steel inner chamber of car chassis, then
Spring C=(C
1+ C
2+ C
3+ C
4+ C
5The crashproof power of this anticollision device of) * 2=1500Kg=14700 newton is 14700 newton.Wherein, the drift of every spring is 200mm.Diameter is 8mm, and the spring external diameter is 416mm, and internal diameter is 400mm, and material is 65Mn.
