Fig. 2 is the structural representation of the energy-absorbing unit that adopts nine hole PVC reinforced plastics pipes and make.
The specific embodiment
Further specify the preferred embodiment of in-vehicle collision mat provided by the utility model below in conjunction with accompanying drawing, it will be appreciated by those skilled in the art that, in-vehicle collision mat of the present utility model is not limited to certain embodiments described herein, but can carry out any modifications and variations under design of the present utility model.
Fig. 1 shows the scheme drawing of the preferred implementation of in-vehicle collision mat of the present utility model.This collision mat is installed in the afterbody of Construction traffic usually, is used for cushioning the collision of rear moving vehicle.As can be seen from the figure, this in-vehicle collision mat comprises the link span 1 that is used to connect vehicle, two buffer cells 2 and end plates 3.Two buffer cells 2 are connected between link span 1 and the end plate 3 in series connected mode, and each buffer cell 2 further comprises two side plates that are oppositely arranged 21 and is connected connecting panel 22 between the described side plate 21.In the preferred embodiment, two continuous buffer cell 2 shared connecting panels 22, and constitute the part of link spans 1 or end plate 3 at a buffer cell and link span 1 bonded assembly, one end and another buffer cell and end plate 3 bonded assemblys one end connecting panel 22.Between side plate 21, form the buffer zone of two rectangles by above-mentioned connection mode, in the present embodiment, also be respectively arranged with energy-absorbing unit 4 in the buffer zone.Also be provided with in the in-vehicle collision mat of the present utility model and energy-absorbing unit 4 kept or be fixed on holding element (not shown) in the buffer zone, such as, can near ground-surface sides base plate be set or the energy-absorbing unit be remained in the buffer zone at side plate 21 by other suitable element.
It will be appreciated by those skilled in the art that, in in-vehicle collision mat of the present utility model and nonessentially comprise two buffer cells 2, can select fully to include only a buffer cell 2 according to the difference of impact strength in the practical application, perhaps comprise plural buffer cell.And, also can not place energy-absorbing unit 4 in the buffer zone in buffer cell, this depends on the difference of impact strength in the concrete application too.
In in-vehicle collision mat of the present utility model, when bumping, side plate 21 is subjected to pushing longitudinally and deforming even structural destruction along it, and then absorbs or consume collision energy
Preferably, be formed on the structure that can guide side plate 21 edge directions away from each other outwards to bend under vertical squeezing action, perhaps be called bending part at the middle part of side plate 21.Like this, when collision, whole buffer cell 2 is owing to side plate 21 outwardly-bent deforming, the connecting panel 22 at two ends is close to each other under the effect of squeese pressure, when being provided with energy-absorbing unit 4 in the buffer zone, connecting panel 22 can deform it even structural destruction in extruding energy-absorbing unit 4, and then absorbs and the consumption collision energy.According to conservation of energy theorem, other relevant portion in side plate 21, energy-absorbing unit 4 and collision mat deforms and during structural failure, the kinetic energy of moving vehicle is consumed and speed reduces, simultaneously the Construction traffic that hit of the place ahead also can't be subjected to very big application force, so stop (during its kinetic energy by consuming with ground-surface friction) after the slight distance that can not move forward or move forward.
The guiding side plate 21 outwards structure of bending can form by various ways, can form by two parts such as side plate, these two parts form slightly bandy angle each other, thereby the guiding side plate is outwardly-bent when receiving extruding, these two parts can fixed to one anotherly connect, and also can connect by the pivotally attached mode to be easier to deform.Alternatively, whole side plate 21 also can be made circular-arc, and then squeese pressure relatively is evenly distributed on the whole length of side plate.
Because collision mat is the destruction of reasonable distortion by its structure and energy-absorbing material to be absorbed and clears up collision energy, therefore when selecting the material of collision mat each several part, need take all factors into consideration intensity, the energy absorption characteristics of material and take into account its durability.
In this preferred embodiment, the skeleton support section of collision mat all adopts the Q235 steel to make, this makes whole in-vehicle collision mat have certain rigidity, can crash collides provides enough, effective supporting, simultaneously make total have certain durability again, and the controlled deformation by steel structure, realize controlled to vehicle movement track and state.Certainly, the skeleton support section of collision mat is not limited to steel, and other can provide suitable rigidity and be suitable for guiding the material of collision mat deformation all can use.
Usually, energy-absorbing unit 4 can adopt following material to make: PVC reinforced plastics, Sandwich reinforcing material or glass-reinforced plastic material.
PVC reinforced plastics tooling cost lower, draw materials convenient and energy-absorbing efficient height.In preferred embodiment of the present utility model, energy-absorbing material adopts nine hole PVC reinforced plastics pipes, and the destruction of nine hole pipes and distortion absorb energy when utilizing collision.
Fig. 2 shows the structure that adopts the energy-absorbing unit that nine hole PVC reinforced plastics pipes make.Can see that energy-absorbing unit 4 is made up of a plurality of subelements 40, each subelement is nine hole PVC reinforced plastics pipes.It will be understood by those skilled in the art that according to the concrete needs of using and to adjust the aperture of nine hole PVC reinforced plastics pipes and the ratio of wall thickness, and then change its distortion and energy absorption characteristics.
The Sandwich reinforcing material is on the basis of PVC reinforced plastics, has increased the netted honeycomb structure of one deck in the centre, when energy-absorbing is provided, has material monolithic preferably, is difficult for broken and has increased the integral rigidity of material; The Sandwich material is that two parts are formed, the i.e. PVC reinforced plastics of Zhong Jian cellular knitting and outside, cellular knitting is raw MAT'L with the terylene, by braider braiding becoming net structure, cover with hot melt PVC material on these knitting both sides, and form by grinding tool typing cooling.
Preferably, energy-absorbing unit 4 can also be made by glass-reinforced plastic material, and the glass-reinforced plastic material performance is between steel and PVC material, both had certain intensity, can pass through reasonable structural design again, make it that large deformation and destruction be taken place under impact conditions, thereby become a kind of good energy-absorbing material.
Usually, for easy to use, in-vehicle collision mat of the present utility model so that the dismounting mode be connected with vehicle.Such as can the link span of collision mat and the crossbeam of automobile tail being coupled together by high strength bolt.When needs are used collision mat always, can be equipped with hydraulic gear, thus the adjusting of the folding and unfolding of the collision mat of being more convenient for and position.
In addition, can also the collision mat shell be set for in-vehicle collision mat of the present utility model, its material be such as can selecting thin steel for use, thereby can not influence the effect of its distortion and energy-absorbing when improving the collision mat outward appearance.
Surperficial Pasting or coating reflective membrane or warning mark at collision mat (or its shell), even light fixture can be set, thereby under various application conditions, can both utilize himself color and/or reflective (luminous) characteristic that the chaufeur of vehicular traffic is played warning function.
In a preferred embodiment of the invention, the position of link span 1 and vehicle connecting bridge is set to be higher than the center of gravity of in-vehicle collision mat.Like this, when being subjected to clashing into, collision mat is easier to deflect down, thereby can prevent effectively that moving vehicle from piercing construction ahead vehicle bottom.
