In one embodiment of the invention, as indicated in figures 19 and 22, at least one of the front end of the front end at the top of upper buckle 20a and the bottom of lower pinch plate 30a is provided with the first energy-absorbing district 21a, first energy-absorbing district 21a is formed as the arc caved inward along the longitudinal direction, and the first 21a periphery, energy-absorbing district is formed with reinforced rib.Such as, as indicated in figures 19 and 22, the front end at the top of upper buckle 20a is provided with the first energy-absorbing district 21a, first energy-absorbing district 21a is recessed into downwards from the top of upper buckle 20a, first periphery, energy-absorbing district is formed with the reinforced rib of annular, like this, first energy-absorbing district 21a is set in energy-absorption box 10a front portion, and use reinforcing rib structure in the first 21a peripheral region, energy-absorbing district, surrounding is around realizing energy-absorption box 10a reduced cross-sectional, play the effect of collision deformation guiding, and play main directional tagging when energy-absorption box 10a runs into collision, be first out of shape.

According to one embodiment of present invention, the rear of the first energy-absorbing district 21a is formed with the second energy-absorbing district 22a that at least one caves inward.In one of them example of the present invention, the midway location at the top of upper buckle 20a is formed with the second energy-absorbing district 22a to lower recess.Weld location for the ease of upper buckle 20a and lower pinch plate 30a, further, the bottom of the second energy-absorbing district 22a is formed with the first platform part 221a, the first platform part 221a is formed with the first knock hole 222a.Thus, by increasing one-level areal of stress concentration, the stability of energy-absorption box 10a collision deformation guiding can be improved further, and the areal of stress concentration of the second energy-absorbing district 22a is as auxiliary navigation designing, reduced cross-sectional is relatively less, while guarantee distortion guiding, promote its energy-absorbing effect as much as possible.

As Figure 19, Figure 20 and Figure 21, further, the rear end at the top of upper buckle 20a is formed with the second energy-absorbing district 23a to lower recess.Correspondingly, the bottom of the second energy-absorbing district 23a is formed with the second platform part 231a, the second platform part 231a is formed with the second knock hole 232a.Due to be positioned at the second energy-absorbing district 23a at rear portion structure and effect be positioned in the middle part of the second energy-absorbing district 22a structure and act on similar, therefore repeat no more.

As Figure 19, Figure 20 and Figure 21, according to one embodiment of present invention, the front end of lower pinch plate 30a, midway location and rear end are formed with four energy-absorbing district 31a, the five energy-absorbing district 32a corresponding with the first energy-absorbing district 21a, the second energy-absorbing district 22a and the second energy-absorbing district 23a and the 6th energy-absorbing district 33a respectively, and the 4th energy-absorbing district 31a and the first energy-absorbing district 21a symmetrical configuration, second energy-absorbing district 22a symmetrical configuration of the 5th energy-absorbing district 32a and midway location, the second energy-absorbing district 23a symmetrical configuration of the 6th energy-absorbing district 33a and rear end.Correspondingly, the 5th energy-absorbing district 32a and the 6th energy-absorbing district 33a is formed with the platform part corresponding with the second energy-absorbing district 23a of the second energy-absorbing district 22a of midway location and rear end and knock hole respectively.The 26S Proteasome Structure and Function of the 4th energy-absorbing district 31a, the 5th energy-absorbing district 32a and the 6th energy-absorbing district 33a and the 26S Proteasome Structure and Function of the first energy-absorbing district 21a, the second energy-absorbing district 22a and the second energy-absorbing district 23a similar, therefore repeat no more.

As Figure 19, Figure 20 and Figure 21, the front end of energy-absorption box 10a can be provided with multiple structure energy-absorbing district similar to the first energy-absorbing district 21a, when energy-absorption box 10a collision deformation, can play the main directional tagging that energy-absorption box 10a is out of shape.And be positioned at the second energy-absorbing district 22a and the 5th energy-absorbing district 32a and the 6th energy-absorbing district 33a at middle part and rear portion, the effect realizing distortion guiding is only arranged at energy-absorption box 10a above-below direction, postmedian areal of stress concentration is as auxiliary navigation designing, reduced cross-sectional area is relatively less, only arrange in the vertical direction, so that while guarantee distortion guiding, promote the energy-absorbing effect of energy-absorption box 10a as much as possible, improve the stability of its collision deformation guiding, and consider the convenience that its technique realizes, control preparation cost.

In one embodiment of the invention, the power needed for the distortion of the first energy-absorbing district is not more than the power needed for the distortion of the second energy-absorbing district, and the power needed for the distortion of the second energy-absorbing district is less than the power needed for front anti-collision beam distortion.Particularly, because front anti-collision beam 100a and energy-absorption box 10a is rigidly connected, when first energy-absorbing district 21a be out of shape needed for power be less than or equal to the second energy-absorbing district 22a and 23 distortion needed for power and the second energy-absorbing district 22a and 23 distortion needed for power be less than front anti-collision beam 100a be out of shape needed for power time, first first energy-absorbing district 21a can absorb collision energy and deform, then the second energy-absorbing district 22a and 23 absorbs collision energy and deforms, or the first energy-absorbing district 21a and the second energy-absorbing district 22a and 23 deforms, and then front anti-collision beam 100a just can deform roughly simultaneously.In another example of the present invention, when the power needed for the second energy-absorbing district 22a is out of shape is not more than the power needed for the second energy-absorbing district 23a distortion, first first energy-absorbing district 21a can absorb collision energy and deform, then the second energy-absorbing district 22a absorbs collision energy and deforms, then the second energy-absorbing district 23a absorbs collision energy and deforms, and is finally only front anti-collision beam 100a and is out of shape.

In brief, energy-absorption box 10a is configured to absorb front collision energy prior to front anti-collision beam 100a.

Such as, when low speed collision such as speed is about 30km/h or is less than 30km/h, preposition energy absorption device distortion energy-absorbing order is followed successively by the first energy-absorbing district 21a on energy-absorption box 10a and the 4th energy-absorbing district 31a, second energy-absorbing district 22a and the 5th energy-absorbing district 32a, second energy-absorbing district 23a and the 6th energy-absorbing district 33a, after the complete crumple of energy-absorption box, front anti-collision beam 100a just can deform, thus, when colliding, distortion energy-absorbing order is the first energy-absorbing district of energy-absorption box successively, second energy-absorbing district, after the complete crumple of energy-absorption box, front anti-collision beam just can deform, reduce the loss of low speed collision, now only need to change energy-absorption box 10a, and front anti-collision beam 100a is reusable.In addition, the mode with bolts due to front anti-collision beam 100a and energy-absorption box 10a links into an integrated entity, and therefore energy-absorption box 10a can directly change after being out of shape, easy to operate.

Thickness, the energy-absorption box 10a of the first upper plate 11a, the first median plate 2a of front anti-collision beam 100a, the first lower plate 12a, the first side plate 13a and the second side plate 14a and energy-absorption box 10a can be arranged according to actual requirement along the length of its axis, have better energy-absorbing effect to make preposition energy absorption device.Preferably, energy-absorption box 10a is connected, such as, by bolted with adopting removably mode between front anti-collision beam 100a and longeron.

Front anti-collision beam 100a in this preposition energy absorption device can adopt aluminum material to extrude bending and molding, and considered the requirement that lightweight, safety and space are arranged when front anti-collision beam 100a designs, structure is simple, light.The cross-sectional plane being connected to the energy-absorption box 10a at front anti-collision beam 100a rear portion is formed roughly in Long Circle, the outer peripheral face of energy-absorption box 10a is designed with respectively three grades of distortion guide frames, realize cross section maximized while, make collision deformation more controlled.

Secondly, with reference to Fig. 1-Figure 11, endergonic structure and erection support 503 are described in detail.

According to one embodiment of present invention, be connected to two longerons 200, last crossbeam 110 such as the 8th crossbeam of 300 rear ends is configured to absorb rear collision energy prior to endergonic structure, and after at this last crossbeam 110, fully distortion has absorbed energy, by endergonic structure, remaining energy is absorbed again, in other words, when rear collision energy is no more than predetermined value, collision energy is all absorbed by this last crossbeam 110, when collision energy is higher than this predetermined value, collision energy is first absorbed by this last crossbeam 110, remaining collision energy is absorbed by endergonic structure again.

Be understandable that, this predetermined value is unsuitable too high, certainly also unsuitable too low, and this predetermined value can preferably absorb how many collision energies according to different automobile types or last crossbeam 110 to be set flexibly, this is all easy understand for the ordinary skill in the art.

Specifically, when colliding after vehicle occurs, impact force and collision energy take the lead in being absorbed by this last crossbeam 110, such as when rear car the speed of a motor vehicle lower than during a certain speed of a motor vehicle as during lower than 30km/h, the energy that rear collision produces may be less, at this moment this last crossbeam 110 can fully be out of shape absorption energy, collision energy is made seldom or to be hardly passed to endergonic structure place, and when the speed of a motor vehicle is higher such as higher than 30km/h time, the energy that rear collision produces may be more, at this moment this last crossbeam 110 can fully be out of shape absorption part energy, thus reduce the energy transmitted to endergonic structure place, absorbed by the collision energy of endergonic structure to remainder again.

Namely, for the ordinary skill in the art, can design adaptively the material of this last crossbeam 110 and structure, the rigidity of this last crossbeam 110 and intensity is made to be in a suitable scope, the rigidity of such as this last crossbeam 110 and intensity are all less than rigidity and the intensity of longeron, when colliding so after occurring, first collision energy is absorbed by this last crossbeam 110, if collision energy is less, can be absorbed completely by this last crossbeam 110, longeron is avoided to deform, last crossbeam 110 after so only need changing breakage and need not longeron being keeped in repair, if collision energy is larger, after then last crossbeam 110 has absorbed collision energy, also can be absorbed by endergonic structure, so just form two-stage energy-absorbing form, thus fully collision energy is absorbed, protection fuel tank, prevent collision energy to be passed to driving compartment forward simultaneously.

It should be noted that, be 30km/h be above only for exemplary purposes for example with the speed of a motor vehicle, can not be interpreted as one restriction of the present invention.

Thus, due to the cause of the endergonic structure of formation on this back segment 204, thus in the rear collision process of the vehicle of such as automobile, in use procedure the distortion of longeron cushion by endergonic structure and absorb, thus can not be delivered near fuel tank, the installing space of fuel tank can not be compressed, and thus, improves the safety of fuel tank.

Simultaneously; by the strength and stiffness of last crossbeam 110 of reasonable design; when making to touch after occurring; collision energy can be absorbed separately by this last crossbeam 110; if collision energy is comparatively large, can be absorbed by endergonic structure further, fully can not only absorb collision energy like this, protect fuel tank and avoid energy to driving compartment transmission; the maintenance cost of longeron can also be reduced simultaneously, there is good practicality.

According to one embodiment of present invention, endergonic structure is multiple, in the process of the plurality of endergonic structure collision after vehicle such as automobile occurs, energy can be absorbed fully, contriver find, the spacing of multiple endergonic structure to the tangible relevance of energy-absorbing effect, on this basis, contriver is drawn by great many of experiments, and when the spacing of multiple endergonic structure is successively decreased according to direction from back to front, energy-absorbing effect is best.

In view of this, spacing in the plurality of endergonic structure between arbitrary neighborhood two endergonic structures is successively decreased towards the direction of the front end of longeron according to the rear end from longeron, in other words, in the plurality of endergonic structure, the spacing of adjacent two endergonic structures reduces from back to front gradually, such as three endergonic structures, last and the spacing of one, centre are greater than middle one and the most previous spacing, i.e. L2 > L1, as shown in Figure 2.

Adopt this design; namely the spacing of multiple endergonic structure changes according to the mode of successively decreasing from back to front; can be out of shape in time to cushion and absorbing forces of impact at each endergonic structure place like this; in time and effectively eliminate the accumulation of energy that longeron is produced by conquassation, further increase the protection to fuel tank.

According to one embodiment of present invention, this last crossbeam 110 is removably located between two longerons.Due to this last crossbeam 110 after touch time can deform, when particularly for collision energy, comparatively I is all absorbed by this last crossbeam 110, adopt this removably design, the replacing of this last crossbeam 110 can be facilitated, thus reduce the maintenance cost of vehicle to a certain extent.

Such as, vehicle frame can comprise two beam seats (scheming not shown), these two beam seats are fixed to the rear end of two longerons respectively, and the two ends, left and right of this last crossbeam 110 are removably disposed on these two beam seats respectively, such as, be fastened by bolts to beam seat.

According to one embodiment of present invention, shown in Fig. 7-Fig. 9, vehicle frame also comprises two erection supports 503, these two erection supports 503 are located at inner side or the outside of two longerons 200,300 respectively, in other words, two erection supports 503 are located at the inner side of two longerons 200,300 respectively, or two erection supports 503 are located at the outside of two longerons 200,300 respectively.Such as; in one embodiment of the invention; with reference to shown in Fig. 7; two erection supports 503 are relatively arranged on the inner side of two longerons 200,300 respectively; body frame structure for automotive can be made so compacter, and longeron 200,300 also can play certain protective effect to the shock absorber be arranged on erection support 503 and spiral spring simultaneously.

Shown in Fig. 8-Figure 11, each erection support 503 includes absorber seat 504 and spiral spring bearing 505, absorber seat 504 and spiral spring bearing 505 are integrally fixed, greatly can improve absorber seat 504 and the rigidity of spiral spring bearing 505 like this, be out of shape after avoiding absorber seat 504 and spiral spring bearing 505 Long-Time Service or damage.Wherein, the shock absorber of vehicle is suitable for being fixed to absorber seat 504, and the spiral spring of vehicle is suitable for being fixed to spiral spring bearing 505.Be understandable that, the shock absorber of vehicle and spiral spring, no longer describe in detail here for prior art known by those skilled in the art.

By absorber seat 504 and spiral spring bearing 505 being arranged on the same side of respective longerons, such as all be arranged on the inner side of respective longerons, thus the installation greatly facilitating spiral spring and shock absorber is fixed, also greatly simplify the structure of erection support 503 simultaneously, and also a saving installing space, facilitate the integral layout of vehicle frame, make the structure of vehicle frame compacter.

And, because spiral spring bearing 505 and absorber seat 504 are integrally fixed structure, thus substantially increase rigidity and the intensity of each bearing, avoid when vehicle travels, because reasons such as shaking, jolt causes spiral spring bearing 505 and absorber seat 504 stressed excessive and be out of shape or damage, and then improve spiral spring bearing 505 and the service life of absorber seat 504, reduce the maintenance cost of vehicle.

As shown in Fig. 2, Fig. 3 Fig. 4 and Fig. 5, according to one embodiment of present invention, this endergonic structure can be configured to energy-absorbing groove 205.By this energy-absorbing groove 205, Impact energy buffering simply easily can be realized, and with low cost.

According to one embodiment of present invention, energy-absorbing groove 205 is formed at least one in the lateral surface 206 of back segment 204 and medial surface 207.In example such as shown in Fig. 1,5, lateral surface 206 and medial surface 207 are all formed with energy-absorbing groove 205, and the spacing of multiple energy-absorbing grooves 205 in lateral surface 206 and medial surface 207 on each side is all successively decrease gradually according to direction from back to front.According to one embodiment of present invention, the whole thickness of the through along the vertical direction longeron of energy-absorbing groove 205, as shown in Figures 3 and 4.And this energy-absorbing groove 205 can be formed as multiple, described multiple energy-absorbing groove 205 is spaced apart from each other along the fore-and-aft direction of longeron.

As shown in Fig. 1,4, each in the lateral surface of back segment 204 and medial surface is equipped with multiple energy-absorbing groove 205, and the multiple energy-absorbing grooves 205 on lateral surface 206 correspond to each other with the multiple energy-absorbing grooves 205 on medial surface 207 and arrange on the Width of longeron.Thus, can cushion and be absorbed in the distortion of longeron 200 in the rear collision process of automobile well, thus the energy preventing collision from producing is passed near fuel tank 400, threatens the safety of fuel tank.

Certainly, the present invention is not limited to this, and in another embodiment of the present invention, the multiple energy-absorbing grooves 205 on lateral surface 206 are interspersed in the longitudinal direction of longeron with the multiple energy-absorbing grooves 205 on medial surface 207.Thus, can cushion and be absorbed in the distortion of longeron in the rear collision process of automobile well, thus the energy preventing collision from producing is passed near fuel tank 400, threatens the safety of fuel tank.

According to one embodiment of present invention, be different in the degree of depth of multiple energy-absorbing grooves 205 of the same side of longeron.Need to illustrate a bit, " the same side " here can be understood as medial surface 207 or the lateral surface 206 of longeron.

Further, be alternately change in the degree of depth of multiple energy-absorbing grooves 205 of the same side of longeron.In other words, the degree of depth of the multiple energy-absorbing grooves 205 on the same side of longeron such as medial surface 207 and/or lateral surface 206 is one dark one shallow, such as the energy-absorbing groove 205 of three on longeron lateral surface 206, last can be darker, one, centre can be more shallow, the most previous then can be darker, to be on different straight lines at the line of multiple such as diapires of three energy-absorbing grooves 205 of this same side like this, namely not conllinear, form the shape of similar multistage broken line, like this when impact force is passed to the plurality of energy-absorbing groove 205 place, the direction of a power can be changed at each energy-absorbing groove 205 place, thus the power reduced to next energy-absorbing groove 205 transmission and energy, make the plurality of energy-absorbing groove 205 can endoergic collision energy more fully, protection longeron and fuel tank, improve the safety of fuel tank.

Certainly, the present invention is not limited thereto, in another embodiment of the present invention, the degree of depth of the multiple energy-absorbing grooves 205 in the same side of longeron according to each energy-absorbing groove 205 and the distance of the rear end of longeron be negative correlation change, that is, energy-absorbing groove 205 is far away apart from the rear end of longeron, and its degree of depth is less.Like this when such as automobile collides after occurring vehicle, most of or all collision energies fully can be absorbed by position energy-absorbing groove 205 rearward, reduce even collision free energy to front transfer, thus the safety of the fuel tank that adequately protects.

According to one embodiment of present invention, the degree of depth of energy-absorbing groove 205 can be 4-6 millimeter, and the degree of depth of such as energy-absorbing groove 205 can be 5 millimeters.According to one embodiment of present invention, the distance between adjacent energy-absorbing groove 205 is greater than 100 millimeters, and the distance preferably between this adjacent energy-absorbing groove 205 can be greater than 200 millimeters.
