In the vehicle energy absorption box that the embodiment of the present invention provides, before being located at tubular energy-absorption box body one end Installing plate, can be fixed on energy-absorption box body in collision prevention girders, more another by being located at tubular energy-absorption box body The rear installing plate of one end, can be fixed on energy-absorption box body on longeron, thus energy-absorption box body is fixed Between collision prevention girders and longeron, wherein, energy-absorption box body sidewall is provided with the crumple groove caving inward. With Automobile runs at a low speed to issue and touches before death into example, in the present embodiment, at least one sidewall of energy-absorption box body Be provided with the guided plate with weakening structure, the corresponding crumple groove of the weakening structure region of this guided plate arranges, from And when touching before automobile generation low speed, collision energy passes in vehicle energy absorption box by front anti-collision beam, energy-absorption box Crumple groove on body sidewall can crumple energy-absorbing, simultaneously weak in the guided plate on energy-absorption box body sidewall Change malformation, due to the corresponding crumple groove of this weakening structure region, when therefore weakening structure is out of shape, can draw Lead the quick crumple of crumple groove, for actual collision situation, the quick crumple of crumple groove can improve energy-absorption box The uniformity of bulk deformation, thus the energy-absorbing effect that improves vehicle energy absorption box; And, guided plate weak Change structure self-deformation, also can absorption portion collision energy, thus further increase vehicle energy absorption box Energy-absorbing effect.
Particularly, for the energy-absorption box body 11 of tubular, it has generally included header board and has passed through weldering Connect the rear plate being connected with header board, thus form the tubular energy-absorption box body 11 with four faces. Therefore, can With by four sidewalls of energy-absorption box body 11, guided plate 12 is all set, thus in the mistake of car crass Cheng Zhong, makes guided plate 12 fully guide the quick crumple of crumple groove 10 of energy-absorption box body 11 from four sides, Reach the effect of abundant energy-absorbing. When practical application, ensureing that guided plate 12 guides crumple groove 10 quick Under the prerequisite of crumple, save material cost simultaneously, conventionally the structure of energy-absorption box body 11 identical upper, Lower surface arranges guided plate 12, and namely guided plate 12 includes two, and correspondence is located at energy-absorption box body respectively 11 upper and lower surface.
Wherein, taking the upper surface of energy-absorption box body 11 as example, which is provided with the crumple groove for crumple energy-absorbing 10, and generally for the integral energy-absorbing ability and the effect that improve vehicle energy absorption box, conventionally arrange at upper surface Multiple spaced crumple grooves 10, and preferably the structure of crumple groove 10 is strip structure, thus increase The crumple scope of crumple groove 10 self. This wherein, due to the automobile central collision of vehicle energy absorption box dominant absorption or after The collision energy touching, therefore the bearing of trend of strip crumple groove 10 is conventionally perpendicular to energy-absorption box body 11 The bearing of trend of upper surface, ideally, the bearing of trend of energy-absorption box body 11 upper surface is automobile Central collision or after the bearing of trend of the direction, the strip crumple groove 10 that touch perpendicular to table on energy-absorption box body 11 The bearing of trend in face. Given this, along the bearing of trend of energy-absorption box body 11 upper surface, multiple strips are burst Contracting groove 10 is parallel, equidistantly setting, ensures the uniformity of the overall crumple of automobile energy-absorbing box body 11, improves Energy-absorbing effect.
Accordingly, as shown in Figure 2, guided plate 12 can comprise be fixed on energy-absorption box body 11 non-burst The fillet 21 in contracting groove 10 region, is namely fixed on energy-absorption box body by fillet 21 by guided plate 12 On 11 upper surface; In fig. 2, guided plate 12 also comprises with fillet 21 and being connected, simultaneously right Answer crumple groove 10 region to be formed with the extension edge 22 of weakening structure, thus automobile is when collision occur, fixing Fillet 21 motionless (only with the crumple campaign of energy-absorption box body 11, there is not crumple in self, Damage etc. may be there is), thus the weakening structure on extension edge 22 is out of shape by the impact of impact force, completes To the quick guiding function of crumple groove 10 crumple.
Be specifically as follows, as depicted in figs. 1 and 2, be provided with three with energy-absorption box body 11 upper surface and burst Contracting groove 10 is example, and the fillet 21 of corresponding guided plate 12 is provided with four, and four fillets 21 Be located at respectively between adjacent crumple groove 10 and outermost crumple groove 10 two ends, thus make to be connected to connection Extension edge 22 on limit 21 arranges in corresponding crumple groove 10 region well. Wherein, in order to make collision Advocate will transmit and act on extension edge 22, fillet 21 can be parallel to crumple groove 10 and arrange, Thus make automobile generation forward collision or oblique when waiting collision, impact force maximum suffered by fillet 21, then makes The impact force that is delivered to extension edge 22 maximizes, and is convenient to the distortion of the weakening structure 23 on extension edge 22.
In FIG, four same ends of fillet 21 are located on the same line, and with energy-absorption box body 11 The lateral edges of upper surface be arranged in parallel, thus when weakening structure extension edge 22 on distortion can be ensured, draws The deformation direction of guide plate 12 is the crumple direction of energy-absorption box body 11, to ensure quick under guiding function Crumple energy-absorbing. In Fig. 1 and Fig. 2, extension edge 22 is connected between the same side of adjacent fillet 21, And the corresponding crumple groove of extension edge 22 region is formed with drift angle, and is provided with weakening structure 23 at drift angle place; Wherein, In Fig. 1 and Fig. 2, include spaced four fillets 21, therefore guided plate 12 can include eight Individual extension edge 22, namely fillet 21 is equipped with four with side.
Wherein, in Fig. 1 and Fig. 2, extension edge 22 can comprise two free margins 24 of isometric setting, and two The lateral edges that the drift angle that individual free margins 24 forms closes on energy-absorption box body 11 upper surface arranges, thus works as vapour When car collides, under the effect of impact force and weakening structure, two free margins 24 can be made mutual Draw close, compression, thus guide crumple groove 10 along the deformation direction crumple of guided plate 12, reach fast The effect of speed crumple. This wherein, two angles of free margins 24 of an extension edge 22 are less, then get over Easily deform, guiding function is better.
In fig. 1 and 2, adjacent fillet 21 forms jointly with the extension edge 22 being positioned between the two A hexagonal structure, and this hexagonal structure is in fig. 2, is symmetrical junction in X direction with Y-direction Structure, thus when ensureing on the upper and lower surface that it is fixed on energy-absorption box body 11, can in impact force effect Under, deflection is identical everywhere, thus reaches homogeneous deformation, so that guide crumple groove fast, uniformly Crumple. Wherein, in Fig. 1 and Fig. 2, include three above-mentioned hexagonal structures, hexagonal structure is for closing Ring structures, can ensure the stability that impact force is transmitted, be convenient to the distortion of guided plate.
