Adelomorphic anti-collision bumper of car of the present invention has adopted three groups of gradual distortion Cushioning Design, fully uses physical impact toughness and mechanics advantage.Can be with the impact force efficient absorption 60-80% of car.Energy-absorbing plate adopts the thin steel sheet spring to make, have the buffering energy-absorbing effect and restore performance, it and energy-absorbing plate prop up and are configured to horizontal sliding structure, so that energy-absorbing plate is retractable when collision deformation, again before the warp, the connection of back guide pipe and steady ring and car longeron constitute longitudinal sliding motion formula structure, the rubber Friction disk adopts the rubber with high strength coefficient of friction to make, it is wiped the resistance that forms with buffing energy efficient is absorbed, the condition that the friction energy-absorbing does not rebound and discharges on mechanics, there is not the flutter failure rate, rubber energy-absorbing core is the pressure assembling, it is the cylindrical buffering energy-absorbing spare made from high-tension rubber, it constitutes reasonably with the rubber Friction disk in collision, and work cooperates, doing the surplus energy after energy-absorbing plate and the absorption of rubber Friction disk further, buffering absorbs, and under the mechanical function of rubber Friction disk, controlled the physical condition that bounce-back discharges, actv. keeps soft contact the between vehicle body and the collision body, avoids the injury to vehicle body and occupant.
Description of drawings
Below in conjunction with accompanying drawing the present invention is described in further detail:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A section-drawing of Fig. 1;
Fig. 3 is the structural representation of outer shroud 13.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the car hidden energy-absorbing bumper, energy-absorbing plate 8 support assemblies are end housing 9 inboards before bumper/spoiler, energy-absorbing plate 8 inboard two ends are fixed with an energy absorption device 15 that structure is identical respectively, bossed Location resilient piece 12 is installed at energy-absorbing plate 8 inboard two ends, energy-absorbing plate support 7 insertions fixing with energy absorption device 15 1 ends are installed in the Location resilient piece 12, and energy absorption device 15 forms horizontal sliding structure with energy-absorbing plate 8; Energy absorption device 15 comprises preceding guide pipe 6, back guide pipe 3 and rubber energy-absorbing core 11, the front end slip cap of preceding guide pipe 6 is contained in guide pipe 3 tube chambers of back, the steady ring 5 that is installed in back guide pipe 3 front ends is installed on outside the outer shroud 13 of preceding guide pipe 6 front ends, outer shroud 13 and preceding guide pipe 6 form for whole car system, preceding guide pipe 6 and back guide pipe 3 are sliding structure, rubber energy-absorbing core 11 is installed in preceding guide pipe 6 and guide pipe 3 inside, back behind the suit, its two ends are fixed with the tube chamber bottom of preceding guide pipe 6 and back guide pipe 3 respectively, rubber energy-absorbing core 11 is " I " font, and its two ends are fixed with the tube chamber bottom close fit of preceding guide pipe 6 and back guide pipe 3 respectively.The bottom of preceding guide pipe 6 is fixed on the energy-absorbing plate support 7, and the bottom of back guide pipe 3 is fixed on the longeron assembly parts 2, longeron assembly parts 2 and 1 fastening connection of car longeron.Rubber Friction disk 10 is the tack taper, rubber Friction disk 10 is on the 4 road axial lines that level is installed in back guide pipe 3 chamber walls, after passing, it exposes the friction part behind the tube wall of guide pipe 3, pressing plate 4 is fixed and is installed on the tube wall of back guide pipe 3, the top, the tube wall outside of preceding guide pipe 6 is the friction slideway 14 of arc-shaped transition, and the outer shroud 13 and rubber Friction disk 10 correspondence positions of the front end of preceding guide pipe 6 have sliding tray 16.
The principle of work of Adelomorphic anti-collision bumper of car of the present invention is as follows: the car that is equipped with this Adelomorphic anti-collision bumper is when being collided, end housing 9 and energy-absorbing plate 8 stress deformation and produce the buffering energy-absorbing effect simultaneously before the bumper/spoiler of car, when arc energy-absorbing plate 8 is collided horizon, its bounce-back toughness reduces, and the impact force of car is transformed into the energy absorption device 15 at two ends.Preceding guide pipe 6 stressed back compressing rubber energy-absorbing core 11 vertically-guideds, the tube wall of guide pipe 6 before rubber Friction disk 10 pins by arc friction slideway 14, thereby produce the chain energy-absorbing effect of friction and ductile buffer, the horizontal powerful friction of vertical buffering toughness of rubber energy-absorbing core 11 and rubber Friction disk 10 forms huge soft resistance, make impact force and velocity of impact moment reduction, thereby produce the effective energy-absorbing rate, preceding guide pipe 6 and rubber energy-absorbing core 11 are pinned by rubber Friction disk 10 in the land of buffering energy-absorbing, make the release that can not rebound of the energy of rubber energy-absorbing core 11, will restore to the original state through guide pipe 6 before manually unclamping rubber Friction disk 10 and making and rubber energy-absorbing core 11 after the collision.
