Technical field
The utility model relates to a kind of self-propelled vehicle shell.
Background technology
Automobile is as a kind of modern walking-replacing tool, and along with improving constantly of people's living standard, its popularity is also more and more higher, but the safety problem that thereupon produces also can not be ignored.According to the statistical figure that the World Health Organigation delivers, global traffic accident causes 1,200,000 people's death every year on average.Traffic accident death has become global violence and the dead important component part of injury, constitutes the significant problem of harm humans health and development.How to improve the safety of automobile, the generation that reduces casualty accident has become a very urgent problem that needs solution.The used sheet material of existing self-propelled vehicle shell is solid steel plate, relies on the deformation that steel plate takes place can absorb the impulsive contact force of a part when having an accident, thereby alleviates the collision that the occupant directly is subjected to.Yet the intensity of steel plate is limited after all, when being subjected to stronger collision in the automobile part, can't absorb a lot of impulsive contact forces, even rupture sometimes, can not ensure occupant's life security effectively.
Summary of the invention
The purpose of this utility model has provided a kind of self-propelled vehicle shell, and it can absorb more impulsive contact force when being subjected to colliding, and easy fracture not can farthest ensure occupant's safety.
The purpose of this utility model is achieved through the following technical solutions: the self-propelled vehicle shell, shell is to be made by multilayer composite board, multilayer composite board comprises outer metal level, the top of outer metal level is provided with the high strength skin of accelerator processing, the bottom of outer metal level is provided with the collision cushion layer, and the bottom of colliding cushion layer is provided with inner metal layer.
For further realizing the purpose of this utility model, can also realize by the following technical solutions: collide several high resiliency supporting layers that be arranged in parallel in the cushion layer, at a distance of certain distance, the distance between adjacent two high resiliency supporting layers is 1: 2 with the width ratio of high resiliency supporting layer between adjacent two high resiliency supporting layers.Anti-fracture fleece is set in the inner metal layer, and anti-fracture fleece is made of several parallel vertical fibers cross fiber intersection parallel with several, and vertical fiber is vertical with cross fiber.The transversal surface of cross fiber and vertical fiber is circular, and this round diameter is 1.5-3mm.The transversal surface of high resiliency supporting layer is a rectangle.The outer field thickness of high strength of accelerator processing is 150-260 μ m.
Good effect of the present utility model is: the utility model reasonable in design, and effect is remarkable, when being subjected to colliding, its in-to-in structure can be conducted impulsive contact force towards periphery, increase area of thrust surface, thereby absorb more impulsive contact force, reduced the injury that the occupant directly is subjected to.Its in-to-in fleece can prevent the sheet material fracture by actv. simultaneously, further ensures occupant's safety.The surface of self-propelled vehicle shell is provided with the high strength skin of accelerator processing, and this layer can improve the surface strength of self-propelled vehicle shell, makes the long-term use of self-propelled vehicle shell indeformable.
Description of drawings
Fig. 1 is a structural representation of the present utility model; Fig. 2 is the section structure for amplifying scheme drawing that constitutes the multilayer composite board of self-propelled vehicle shell; Fig. 3 is the structural representation of looking up of Fig. 2.
Number in the figure: the high strength outer 3 outer metal levels 4 of 1 self-propelled vehicle shell, 2 accelerators processing collide cushion layer 5 high resiliency supporting layers 6 inner metal layers 7 anti-fracture fleeces.
The specific embodiment
Self-propelled vehicle shell described in the utility model, shell is to be made by multilayer composite board, and multilayer composite board comprises outer metal level 3, and the top of outer metal level 3 is provided with the high strength skin 2 of accelerator processing, the bottom of outer metal level 3
Be provided with and collide cushion layer 4, the bottom of colliding cushion layer 4 is provided with inner metal layer 6.The high strength skin 2 of accelerator processing is the high strength protective cover that is formed by electron irradiation radiation from machine outer metal level 3 surfaces; the high strength outer 2 of accelerator processing improves wear-resistant, the shock proof performance of self-propelled vehicle shell, and makes the long-term use of self-propelled vehicle shell indeformable.The thickness of inner metal layer 6 is greater than the thickness of outer metal level 3, and inner metal layer 6 plays main supporting role in the self-propelled vehicle shell.
For improving the impact resistance of self-propelled vehicle shell, and the self-propelled vehicle shell can be resiled after being hit, prevent the distortion that is hit of self-propelled vehicle shell, the situation that the occupant is blocked takes place, several high resiliency supporting layers 5 can be arranged in parallel in colliding cushion layer 4, at a distance of certain distance, the distance that adjacent two high resiliency supporting layers are 5 is 1: 2 with the width ratio of high resiliency supporting layer 5 between adjacent two high resiliency supporting layers 5.Colliding cushion layer 4 and high resiliency supporting layer 5 all is to be made by elastomeric material, collide the hardness of the hardness of cushion layer 4 less than high resiliency supporting layer 5, when the self-propelled vehicle shell is subjected to the quick and very brief impact of external force, 5 main bufferings of high resiliency supporting layer and supporting role; When the self-propelled vehicle shell is subjected to slow and lasting impact, collide 4 main buffer actions of cushion layer.The rigidity of high resiliency supporting layer 5 is stronger, is subjected to can recover original shape after the external impacts distortion, can guarantee occupant's safety.For the buffering effect that makes the self-propelled vehicle shell reaches the best and cost-cutting, according to the repeated multiple times result of experiment, can be as shown in Figure 2, several high resiliency supporting layer 5 parallel dispersions are arranged on collide in the cushion layer 4, and the width ratio of the distance that makes 5 of adjacent two high resiliency supporting layers and high resiliency supporting layer 5 is 1: 2.Collide cushion layer 4 and high resiliency supporting layer 5 and all have good effect of heat insulation, can reduce heat transmission between outer metal level 3 and the inner metal layer 6 effectively, make the self-propelled vehicle shell have certain heat-insulating property, thereby reach certain energy-saving effect.
Not easy to crack for guaranteeing that the self-propelled vehicle shell is subjected under the effect of external force; guarantee occupant's personal safety; anti-fracture fleece 7 can be set in inner metal layer 6; anti-fracture fleece 7 is made of several parallel vertical fibers cross fiber intersection parallel with several, and vertical fiber is vertical with cross fiber.Anti-fracture fleece 7 is made by the non-metallic material of high resiliency good-toughness.
For guaranteeing that anti-fracture fleece 7 plays the good effect that prevents self-propelled vehicle shell cracking, in the prerequisite that guarantees the to reach above-mentioned effect purpose cheaply that descends, can the cross-sectional design of cross fiber and vertical fiber is circular, and to make this round diameter be 1.5-3mm.
Reach a conclusion through testing repeatedly, when the transversal surface of high resiliency supporting layer 5 is rectangle, buffering effect the best that high resiliency supporting layer 5 plays.
Learn through experiment repeatedly, when the thickness of the high strength skin 2 of accelerator processing is 150-260 μ m, can under the prerequisite of guaranteeing self-propelled vehicle shell high strength, high resiliency and high security, manufacturing cost be dropped to minimum.The utility model not technology contents of detailed description is known technology.
