Abstract
The utility model relates to a vehicle bumper for energy adsorption and collisions damping, which comprises an outer decorative bumper and also comprises a honeycomb body with honeycomb structure, and a reinforced connecting bumper, wherein, the front end face of the honeycomb body is directly fixed the center of the inner side of the outer decorative bumper; the reinforced connecting bumper is positioned on the rear end face of the honeycomb body and is connected into one body with outer decorative bumper through bolts. At the moment that vehicles generate a collision, the honeycomb structure of the honeycomb body can adsorb collision energy and play the role of protecting the vehicles.
Description
The utility model has related to that a kind of automobile energy-absorbing is slow to hit bumper/spoiler, a kind of bumper/spoiler of protection automobile when it is automobile generation middling speed, low speed collision.
Become backbone industry already in China garage, existing automobile has reached up to ten million, but the traffic accident on the road also progressively rises, during automobile generation head-on crash in travelling, impact is by bumper/spoiler and knocked object generation rigid impact, thereby causes the damage of vehicle or personnel's injures and deaths.
Chinese patent ZL97220557.8 discloses the slow bumper/spoiler that hits of automobile energy-absorbing, this device is by the top layer thick stick, the reinforcement protection thick stick, the slow energy absorbent block of hitting of air bag constitutes, symmetric configuration the slow energy absorbent block of hitting of air bag between its mesexine thick stick and the reinforcement protection thick stick, filling the solid elastic weighting material around hitting energy absorbent block in that air bag is slow, air bag is slow to hit energy absorbent block and top layer thick stick by bolt, and nut is connected on the reinforcement protection thick stick.In this utility model,, do not bring into play its due effect fully so delay the absorption collision effect of hitting energy absorbent block because the slow energy absorbent block of hitting is wrapped up with flexible air-bag and rigidity air bag.
The purpose of this utility model is to overcome the slow shortcoming of hitting bumper/spoiler of existing automobile energy-absorbing, provides a kind of and during low speed collision, produce the slow bumper/spoiler that hits of energy-absorbing of moment huge energy in the time of can absorbing auto against in automobile takes place.
In order to realize the purpose of this utility model, the utility model provides a kind of automobile energy-absorbing the slow bumper/spoiler that hits, it comprises: decorate thick stick outward, have the honeycomb ceramics of honeycomb structure and reinforce the connection thick stick, the front end face of honeycomb ceramics directly is fixed on outer central authorities of decorating the thick stick inboard, reinforces to connect thick stick and be connected as a single entity by bolt and outer decoration thick stick on the aft end face of honeycomb ceramics.
The utility model provides a kind of automobile energy-absorbing the slow bumper/spoiler that hits, wherein: it also is included in the isocyanurate foam of casting between described outer inside upper surface, lower surface and the honeycomb ceramics upper surface of decorating thick stick, the lower surface, and decorates one deck isocyanurate foam of casting between the left side, right side of inside left-end face, right side and the honeycomb ceramics of thick stick outside.
The utility model provides that a kind of automobile energy-absorbing is slow to hit bumper/spoiler, and wherein: described honeycomb ceramics is bonding making after by the alloy-steel plate punching press.
The utility model provides a kind of automobile energy-absorbing to delay and has hit bumper/spoiler, and wherein: described honeycomb structure is a polygon.
The utility model provides a kind of automobile energy-absorbing to delay and has hit bumper/spoiler, and wherein: described polygon is a hexagon.
The utility model provides a kind of automobile energy-absorbing to delay and has hit bumper/spoiler, and wherein: the described outer thick stick of decorating is made by composite material.
The utility model provides a kind of automobile energy-absorbing to delay and has hit bumper/spoiler, and wherein: described composite material is glass-felt plastic or engineering plastics.
The automobile energy-absorbing that the utility model provides is slow to be hit bumper/spoiler and compares with the disclosed bumper/spoiler of prior art; because honeycomb ceramics directly is fixed on outer the decoration on the thick stick; so honeycomb ceramics can absorb more collision energy; produce displacement deformation; and energy is distributed on the crossbeam, crossbeam of automobile, to play the effect of protection automobile.
The contrast accompanying drawing is described embodiment of the present utility model in detail below.
Fig. 1 is that the slow section that hits bumper/spoiler of automobile energy-absorbing of the present utility model is bowed to scheme drawing.
Fig. 2 is the slow enlarged diagram that hits the honeycomb ceramics of bumper/spoiler of the utility model automobile energy-absorbing.
As shown in Figure 1, automobile energy-absorbing is slow to be hit bumper/spoiler and comprises: decorate thick stick 1 outward, have the honeycomb ceramics 2 of honeycomb structure 5 and reinforce and connect thick stick 4, wherein the front end face of honeycomb ceramics 2 directly is fixed on outer central authorities of decorating thick stick 1 inboard, reinforce connecting thick stick 4 is connected as a single entity by bolt and outer decoration thick stick on the aft end face of honeycomb ceramics 2, and be connected with various vehicles by bolt, make whole bumper/spoiler become as a whole.Decorate the poly-ammonia ester foam of casting between upper surface, lower surface and honeycomb ceramics 2 upper surfaces, the lower surface of thick stick 1 inboard outside, decorate one deck isocyanurate foam of casting between the left side, right side of left side, right side and the honeycomb ceramics 2 of thick stick 1 inboard outside, isocyanurate foam and the outer thick stick 1 of decorating are connected as a single entity with honeycomb ceramics 2, this spline structure is compact more, and reach the best slow purpose of hitting of energy-absorbing, decorate the thickness of one deck isocyanurate foam of casting between thick stick 1 and the honeycomb ceramics 2 outside and can select according to different vehicles.
As shown in Figure 2, described honeycomb ceramics 2 is bonding making after by the alloy-steel plate punching press, honeycomb ceramics 2 with honeycomb structure 5 is the main energy absorption devices in the bumper/spoiler, utilize the honeycomb self characteristics, and according to the structure of car shape, correspondingly change size, the specification of honeycomb, to reach best energy-absorbing effect, honeycomb structure 5 is a polygon: as hexagon.
The outer thick stick 1 decorated is made by composite material, as glass-felt plastic or engineering plastics, has given full play to the high-strength characteristics of composite material light like this, has promptly alleviated the weight of bumper/spoiler, has increased the intensity of bumper/spoiler again.
Automobile energy-absorbing described in the utility model is slow to be hit bumper/spoiler and is applicable on the various automobile, as using the slow bumper/spoiler that hits of automobile energy-absorbing on Beijing Automobile Workshop's Feitian min-truck, the front end face of honeycomb ceramics 2 directly is fixed on outer central authorities of decorating thick stick 1 inboard, its honeycomb ceramics 2 is of a size of long 740mm, wide 120mm, thick is 120mm, and the honeycomb structure of honeycomb ceramics is a regular hexagon.Decorate the isocyanurate foam of casting between the upper surface, lower surface of inside upper surface, lower surface and the honeycomb ceramics 2 of thick stick 1 outside, and decorate one deck isocyanurate foam of casting between the left side, right side of left side, right side and the honeycomb ceramics 2 of thick stick 1.Reinforce connecting thick stick 4 is connected as a single entity by bolt and outer decoration thick stick on the aft end face of honeycomb ceramics 2.
