At first, describe in detail with reference to the front anti-collision beam 100a of Fig. 1, Figure 12-Figure 22 and energy-absorbing box 10a, wherein this front anti-collision beam 100a and this energy-absorbing box 10a have constituted the preposition energy absorption device of vehicle frame.

In one embodiment of the invention, the height along the vertical direction of the first side plate 13a is less than the height of the second side plate 14a, the upper end of the first side plate 13a is connected to the first upper plate 11a by the first swash plate 131a, and the lower end of the first side plate 13a is connected to the first lower plate 12a by the second swash plate 132a.In the example of Figure 12 and Figure 13, the top of the first side plate 13a is lower than the top of the second side plate 14a, and the bottom of the first side plate 13a is higher than the bottom of the second side plate 14a, simultaneously, the front end of the first upper plate 11a and the first lower plate 12a is positioned at the rear of the first side plate 13a, this moment, the first swash plate 131a upwards extended back from the upper end of the first side plate 13a, the second swash plate 132a extends back from the lower ends downward of the first swash plate 131a, thereby front anti-collision beam 100a principal section makes three-legged structure up and down into, increased the rigidity of front anti-collision beam 100a itself, non-deformability and energy absorption ability when having improved collision.In addition, the Section Design of triangular structure has been saved the arrangement space of front anti-collision beam 100a, the design of the front part of vehicle moulding of being more convenient for.

By the first upper plate 11a, the first median plate 2a of front anti-collision beam 100a and the Thickness Design of the first lower plate 12a are become to make about equally its easier extruding and brake forming, and front anti-collision beam 100a principal section make three-legged structure up and down into, effectively remedied the loss of strength behind the first median plate 2a attenuate.

Alternatively, the angle between the first swash plate 131a and the second swash plate 132a is 30 °-90 °.Preferably, the angle between the first swash plate 131a and the second swash plate 132a is 60 °.For example in the example of Figure 13, the first swash plate 131a and the second swash plate 132a are about the centre plane symmetry at first median plate 2a place, and at this moment, the angle between the first swash plate 131a, the second swash plate 132a and the first median plate 2a is 30 °.

In one embodiment of the invention, first body forms roughly arc, particularly, as Figure 14, Figure 15 and shown in Figure 16, the left side section of first body bends to form the first bending segment 15a left backward, the right section of first body bends to form the second bending segment 16a to the right backward, and the angle between the first bending segment 15a and the second bending segment 16a and the first side plate 13a is respectively α and β, and the scope of angle α and β is all between 5 °-15 °.That is to say, the oblique left back of the left end portion of first body is to being bent to form the first bending segment 15a, the first bending segment 15a and the first body middle part not angle between the first side plate 13a of bending part is α, the oblique right abaft of the right end portion of first body is to being bent to form the second bending segment 16a, and the second bending segment 16a and first body middle part not angle between the first side plate 13a of bending part are β.

For example in the example of Figure 14, the first bending segment 15a and the second bending segment 16a are bent into arc, and the first bending segment 15a and the second bending segment 16a are about the middle vertical plane left-right symmetric of first body.

Alternatively, angle α and β about equally, and angle α and β are 8.8 °.Here, need to prove, " angle α and β are about equally ", can be understood as that angle α and β equate fully or the difference of angle α and β in a very little scope, for example difference range is in classification or second level.Certainly, the invention is not restricted to this, in other examples of the present invention, angle α and β also can be unequal.

In one embodiment of the invention, as shown in figure 13, the thickness of the first upper plate 11a, first median plate 2a, the first lower plate 12a, the first side plate 13a and the second side plate 14a about equally.Here, need to prove, " thickness of the first upper plate 11a, first median plate 2a, the first lower plate 12a, the first side plate 13a and the second side plate 14a about equally ", the thickness that can be understood as the first upper plate 11a, first median plate 2a, the first lower plate 12a, the first side plate 13a and the second side plate 14a equate fully or the thickness difference of the first upper plate 11a, first median plate 2a, the first lower plate 12a, the first side plate 13a and the second side plate 14a in a very little scope, for example difference range is in the millimeter level.

Thus, by the first upper plate 11a, first median plate 2a, the first lower plate 12a, the first side plate 13a and the second side plate 14a being designed to the structure of equal thickness, further reduced the difficulty of processing of front anti-collision beam 100a.Further, the thickness of the first swash plate 131a and the second swash plate 132a also can with the thickness of the first upper plate 11a, first median plate 2a, the first lower plate 12a, the first side plate 13a and the second side plate 14a about equally.

In one embodiment of the invention, be formed with a plurality of mounting hole 3a on first body.As Figure 14 and shown in Figure 16, be formed with ten mounting hole 3a on first body, the upper end of the contiguous first side plate 13a of six mounting hole 3a wherein, the lower end of the contiguous first side plate 13a of other four mounting hole 3a, three mounting hole 3a among six mounting hole 3a of contiguous first side plate 13a upper end are formed on the left end of first body, other three mounting hole 3a are formed on the right-hand member of first body, two mounting hole 3a among four mounting hole 3a of the contiguous first side plate 13a lower end are formed on the left end of first body, two other mounting hole 3a is formed on the right-hand member of first body, alternatively, the mounting hole 3a at two ends, the left and right sides can be about the middle vertical plane symmetry of first body.Alternatively, can be formed with six bolt mounting holes and four on first body via holes are installed, thereby front anti-collision beam 100a can be connected energy-absorbing section before the longeron by six bolts.It will be appreciated that the quantity of mounting hole 3a can require to arrange according to reality, to satisfy actual requirement better.

This front anti-collision beam 100a is by the section optimal design of front anti-collision beam 100a, under the prerequisite that satisfies the collision energy-absorbing requirement, reach light-weight design, save the anterior arrangement space of front anti-collision beam 100a simultaneously, reduce the bending process difficulty of processing, so can be by in front anti-collision beam 100a, increasing first median plate 2a, the method that reduces front anti-collision beam 100a wall thickness reaches the purpose of energy-absorbing.

Energy-absorbing box 10a is described below, and as Figure 17-shown in Figure 22, energy-absorbing box 10a can comprise: go up buckle 20a and lower pinch plate 30a.Particularly, last buckle 20a and lower pinch plate 30a are buckled into roughly octagon mutually, form outwards outstanding arcuate shape at least respectively Yi Bian wherein go up any of buckle 20a, Yi Bian any arcuate shape of outwards giving prominence to that forms at least respectively of lower pinch plate 30a.Like this, with the last buckle 20a of energy-absorbing box 10a and among the lower pinch plate 30a each form outwards outstanding arcuate shape at least on one side, it is little to have solved the energy-absorbing box sectional area that the single octagon of traditional energy-absorbing box or polygonized structure cause, the problem of energy-absorbing effect difference has improved the energy-absorbing effect of energy-absorbing box.

In order further to improve the energy-absorbing effect of energy-absorbing box 10a, according to one embodiment of present invention, the limit that is positioned at opposite side of last buckle 20a and lower pinch plate 30a forms outwards outstanding arcuate shape.Thus, last buckle 20a is corresponding with the structure of lower pinch plate 30a, can play better energy-absorbing effect.

Preferably, as shown in figure 18, according to one embodiment of present invention, the top of last buckle 20a forms arcuate shape to upper process along left and right directions, and the bottom of lower pinch plate 30a forms arcuate shape to lower process along left and right directions.In other words, the cross sectional shape of energy-absorbing box 10a forms similar Long Circle structure, and last buckle 20a and lower pinch plate 30a fasten and by being weldingly connected.Thus, this structure can be brought into play the energy-absorbing effect of energy-absorbing box 10a to greatest extent, improves the safety of automobile.

In one embodiment of the invention, as Figure 19 and shown in Figure 22, at least one of the front end of the bottom of the front end at the top of last buckle 20a and lower pinch plate 30a is provided with the first energy-absorbing district 21a, the first energy-absorbing district 21a forms the arc that caves inward along fore-and-aft direction, and the first energy-absorbing district 21a periphery is formed with reinforced rib.For example, as Figure 19 and shown in Figure 22, the front end at the top of last buckle 20a is provided with the first energy-absorbing district 21a, the first energy-absorbing district 21a is recessed downwards from the top of last buckle 20a, the first energy-absorbing district periphery is formed with the reinforced rib of annular, like this, in energy-absorbing box 10a front portion the first energy-absorbing district 21a is set, and at 21a peripheral region, first energy-absorbing district use reinforcing rib structure, all around around realizing energy-absorbing box 10a reduced cross-sectional, play the effect of collision deformation guiding, and when energy-absorbing box 10a runs into collision, play and dominate to effect, at first distortion.

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 last buckle 20a is formed with the second energy-absorbing district 22a to lower recess.For the ease of last buckle 20a and lower pinch plate 30a welding location, further, the bottom of the second energy-absorbing district 22a is formed with the first platform part 221a, is formed with the first knock hole 222a on the first platform part 221a.Thus, by increasing the one-level areal of stress concentration, can further improve the stability of energy-absorbing box 10a collision deformation guiding, and the areal of stress concentration of the second energy-absorbing district 22a is as auxiliary guiding design, reduced cross-sectional is less relatively, when guaranteeing the 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 last 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, is formed with the second knock hole 232a on the second platform part 231a.Owing to be positioned at the structure of the structure of the second energy-absorbing district 23a at rear portion and effect and the second energy-absorbing district 22a that is positioned at the middle part and act on similarly, so repeat no more.

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

As Figure 19, Figure 20 and Figure 21,, the front end of energy-absorbing box 10a can be provided with a plurality of structures energy-absorbing district similar to the first energy-absorbing district 21a, when energy-absorbing box 10a collision deformation, can play the leading to effect of energy-absorbing box 10a distortion.And be positioned at middle part and the second energy-absorbing district 22a and the 5th energy-absorbing district 32a and the 6th energy-absorbing district 33a at rear portion, only arrange the effect that realizes the distortion guiding at energy-absorbing box 10a above-below direction, the postmedian areal of stress concentration is as auxiliary guiding design, the reduced cross-sectional area is less relatively, only arrange at above-below direction, so that when guaranteeing the distortion guiding, promote the energy-absorbing effect of energy-absorbing box 10a as much as possible, improve the stability of its collision deformation guiding, and taken all factors into consideration the convenience that its technology realizes, the control preparation cost.

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

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

For example, low speed collision for example speed be about 30km/h or during less than 30km/h, preposition energy absorption device distortion energy-absorbing is followed successively by the first energy-absorbing district 21a and the 4th energy-absorbing district 31a on the energy-absorbing box 10a in proper order, the second energy-absorbing district 22a and the 5th energy-absorbing district 32a, the second energy-absorbing district 23a and the 6th energy-absorbing district 33a, after the complete crumple of energy-absorbing box, front anti-collision beam 100a just can deform, thus, when bumping, distortion energy-absorbing order is the first energy-absorbing district of energy-absorbing box successively, the second energy-absorbing district, after the complete crumple of energy-absorbing box, front anti-collision beam just can deform, reduced the loss of low speed collision, only need this moment to change energy-absorbing box 10a, and front anti-collision beam 100a is reusable.In addition, because front anti-collision beam 100a and energy-absorbing box 10a adopt bolted mode to link into an integrated entity, so can directly change after the energy-absorbing box 10a distortion, easy to operate.

The thickness 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-absorbing box 10a, energy-absorbing box 10a can require to arrange along its axial length according to reality, so that preposition energy absorption device has better energy-absorbing effect.Preferably, adopt removably between energy-absorbing box 10a and front anti-collision beam 100a and the longeron that mode is connected, for example can pass through bolted.

Front anti-collision beam 100a in this preposition energy absorption device can adopt aluminum material extruding bending and molding, and front anti-collision beam 100a has taken all factors into consideration lightweight, safety and space layout requirement during design, and is simple in structure, light.The cross-sectional plane that is connected the energy-absorbing box 10a at front anti-collision beam 100a rear portion forms and roughly is Long Circle, and designing respectively on the outer peripheral face of energy-absorbing box 10a has three grades of distortion guide frames, realizing the maximized while of cross section, makes collision deformation more controlled.

Secondly, describe in detail with reference to the endergonic structure of Fig. 1-Figure 11 and erection support 503.

According to one embodiment of present invention, be connected two longerons 200, last crossbeam 110 of 300 rear ends for example the 8th crossbeam is configured to absorb the back collision energy prior to endergonic structure, and after these last crossbeam 110 abundant distortion have absorbed energy, by endergonic structure energy remaining is absorbed again, in other words, when the back 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 absorbed by this last crossbeam 110 earlier, and remaining collision energy is absorbed by endergonic structure again.

Be understandable that, this predetermined value is unsuitable too high, certainly also should not be low excessively, and this predetermined value can be set flexibly according to different automobile types or last crossbeam 110 preferred how many collision energies that absorb, this all is to understand easily for the ordinary skill in the art.

Specifically, when the back collision takes place in vehicle, impact force and collision energy take the lead in absorbing by this last crossbeam 110, for example when the speed of a motor vehicle of back car when being lower than a certain speed of a motor vehicle when being lower than 30km/h, the energy that the back collision produces may be less, at this moment this last crossbeam 110 can fully be out of shape the absorption energy, make collision energy and seldom or hardly can be passed to the endergonic structure place, and when when the speed of a motor vehicle is higher, for example being higher than 30km/h, the energy that the back collision produces may be more, at this moment this last crossbeam 110 can fully be out of shape the absorption part energy, thereby reduce to endergonic structure place energy delivered, absorbed by the collision energy of endergonic structure to remainder again.

Namely; for the ordinary skill in the art; can material and the structure of this last crossbeam 110 be designed adaptively; make the rigidity of this last crossbeam 110 and intensity be in the suitable scope; for example the rigidity of this last crossbeam 110 and intensity are all less than rigidity and the intensity of longeron; when after generation, colliding like this; collision energy is at first absorbed by this last crossbeam 110; then can be absorbed fully by this last crossbeam 110 if collision energy is less; avoid longeron to deform; so only need to change last crossbeam 110 after the breakage and needn't longeron be keeped in repair; if collision energy is bigger; after then last crossbeam 110 has absorbed collision energy; also can be absorbed by endergonic structure, so just form two-stage energy-absorbing form, thereby fully collision energy is absorbed; the protection fuel tank prevents that simultaneously collision energy is passed to driving compartment forward.

Need to prove, be that 30km/h is that example only is for exemplary purposes above with the speed of a motor vehicle, can not be interpreted as a kind of restriction of the present invention.

Thus, because the cause of the endergonic structure that forms on this back segment 204, thereby in the back collision process of the vehicle of for example automobile, the distortion of longeron is cushioned by endergonic structure and absorbs in the use, thereby can not be delivered near the fuel tank, the installing space of fuel tank can be not compressed, thus, improved the safety of fuel tank.

Simultaneously; by intensity and the rigidity that reasonably designs last crossbeam 110; make when after generation, bumping; collision energy can be absorbed separately by this last crossbeam 110; if collision energy more then can further be absorbed by endergonic structure, not only can fully absorb collision energy like this, protect fuel tank and avoid energy to the driving compartment transmission; can also reduce simultaneously the maintenance cost of longeron, have good practicality.

According to one embodiment of present invention, endergonic structure is a plurality of, these a plurality of endergonic structures take place in the striking process of back at vehicle such as automobile, can absorb energy fully, the contriver finds that the spacing of a plurality of endergonic structures is to the tangible relevance of energy-absorbing effect, on this basis, the contriver draws by a large amount of experiments, when the spacing of a plurality of endergonic structures according to from after forward direction energy-absorbing effect the best when successively decreasing.

In view of this, spacing in these a plurality of endergonic structures between any adjacent 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 these a plurality of endergonic structures the spacing of adjacent two endergonic structures from after reduce gradually forward, be example with three endergonic structures for example, last with middle one spacing greater than middle one with the most previous spacing, i.e. L2＞L1, as shown in Figure 2.

Adopt this design; the spacing that is a plurality of endergonic structures be according to from after the mode of successively decreasing forward change; can in time be out of shape at each endergonic structure place like this with buffering and absorbing forces of impact; in time and effectively eliminate the accumulation of energy that longeron is produced by conquassation, further improved the protection to fuel tank.

According to one embodiment of present invention, this last crossbeam 110 removably is located between two longerons.Since this last crossbeam 110 after can deform when bumping, when particularly all being absorbed by this last crossbeam 110 than I for collision energy, adopt this removably design, can make things convenient for the replacing of this last crossbeam 110, thereby reduce the maintenance cost of vehicle to a certain extent.

For example, 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, the left and right sides of this last crossbeam 110 are removably disposed in respectively on these two beam seats, for example by bolted to beam seat.

According to one embodiment of present invention, with reference to Fig. 7-shown in Figure 9, vehicle frame also comprises two erection supports 503, these two erection supports 503 are located at two longerons 200,300 inboard or the outside respectively, in other words, two erection supports 503 are located at two longerons 200,300 inboard respectively, and perhaps two erection supports 503 are located at two longerons 200,300 the outside respectively.For example; in one embodiment of the invention; with reference to shown in Figure 7; two erection supports 503 relatively are arranged on two longerons 200,300 inboard respectively; can make body frame structure for automotive compacter like this, longeron 200,300 also can play the certain protection effect to shock absorber and the spiral spring that is installed on the erection support 503 simultaneously.

With reference to Fig. 8-shown in Figure 11, each erection support 503 includes absorber seat 504 and spiral spring bearing 505, absorber seat 504 is fixed into one with spiral spring bearing 505, can improve the rigidity of absorber seat 504 and spiral spring bearing 505 so greatly, avoid absorber seat 504 and spiral spring bearing 505 to be out of shape or to damage in the use back for a long time.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 are known for prior art and by those skilled in the art, no longer describe in detail here.

By absorber seat 504 and spiral spring bearing 505 being arranged on the same side of respective longerons, for example all be arranged on the inboard of respective longerons, thereby greatly facilitate installing and fixing of spiral spring and shock absorber, also simplified simultaneously the structure of erection support 503 greatly, but also saved installing space, make things convenient for the integral layout of vehicle frame, make the structure of vehicle frame compacter.

And, because spiral spring bearing 505 is fixed into integrative-structure with absorber seat 504, thereby rigidity and the intensity of each bearing have been improved greatly, avoid when vehicle travels, spiral spring bearing 505 and absorber seat 504 are stressed excessively to be out of shape or to damage owing to reasons such as shaking, jolt causes, and then the service life of having improved spiral spring bearing 505 and absorber seat 504, the maintenance cost of reduction 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, can simply easily realize the Impact energy buffering, and with low cost.

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

As shown in Fig. 1,4, be equipped with a plurality of energy-absorbing grooves 205 on the lateral surface of back segment 204 and each in the medial surface, a plurality of energy-absorbing grooves 205 on a plurality of energy-absorbing grooves on the lateral surface 206 205 and the medial surface 207 are in the setting that corresponds to each other of the Width of longeron.Thus, can cushion and be absorbed in the distortion of longeron 200 in the back collision process of automobile well, be passed near the fuel tank 400 thereby prevent from colliding the energy that produces, threaten the safety of fuel tank.

Certainly, the present invention is not limited to this, in another embodiment of the present invention, and a plurality of energy-absorbing grooves 205 on the lateral surface 206 and vertically being interspersed at longeron of a plurality of energy-absorbing grooves 205 on the medial surface 207.Thus, can cushion and be absorbed in the distortion of longeron in the back collision process of automobile well, be passed near the fuel tank 400 thereby prevent from colliding the energy that produces, threaten the safety of fuel tank.

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

Further, the degree of depth at a plurality of energy-absorbing grooves 205 of the same side of longeron is alternately to change.In other words; for example the degree of depth of a plurality of energy-absorbing grooves 205 on medial surface 207 and/or the lateral surface 206 is one dark one shallow in the same side of longeron; be example with three the energy-absorbing grooves 205 on the longeron lateral surface 206 for example; last can be darker; one of centre can be more shallow; the most previous then can be darker; line at a plurality of for example diapires of three energy-absorbing grooves 205 of this same side will be on the different straight lines like this; it namely not conllinear; form the shape of similar multistage broken line; like this when impact force is passed to these a plurality of energy-absorbing grooves 205 places; can change the direction of a power at each energy-absorbing groove 205 place, thereby reduce to power and the energy of next energy-absorbing groove 205 transmission, feasible these a plurality of energy-absorbing grooves 205 are the endoergic collision energy more fully; protection longeron and fuel tank, the safety that improves fuel tank.

Certainly, the invention is not restricted to this, in another embodiment of the present invention, being negative correlation ground in the degree of depth of a plurality of energy-absorbing grooves 205 of the same side of longeron according to the distance of each energy-absorbing groove 205 and the rear end of longeron changes, that is to say, energy-absorbing groove 205 is more far away apart from the rear end of longeron, and its degree of depth is more little.When the back collision took place vehicle such as automobile, the energy-absorbing groove 205 after most of or all collision energies can be leaned on by the position fully absorbed like this, and reduce even avoid collision 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 the 4-6 millimeter, and for example the degree of depth of energy-absorbing groove 205 can be 5 millimeters.According to one embodiment of present invention, the distance between the adjacent energy-absorbing groove 205 is greater than 100 millimeters, and preferably the distance between this adjacent energy-absorbing groove 205 can be greater than 200 millimeters.

As shown in Fig. 3 and Fig. 4, be equipped with three energy-absorbing grooves 205 on the lateral surface 206 of back segment 204 and each in the medial surface 207, in three energy-absorbing grooves 205 apart from the longeron rear end nearest energy-absorbing groove 205 and the distance between the energy-absorbing groove 205 of centre greater than 200 millimeters, these three energy-absorbing groove middle distance longeron rear end energy-absorbing groove 205 and distances between the energy-absorbing groove 205 of centre farthest are not more than 150 millimeters, namely this farthest energy-absorbing groove 205 and the distance between the middle energy-absorbing groove 205 between 100mm-150mm.Adopt the design of this spacing, can further cushion and be absorbed in the distortion of longeron 200 in the back collision process of automobile, be passed near the fuel tank 400 thereby prevent from colliding the energy that produces.

According to one embodiment of present invention, the cross-sectional plane of energy-absorbing groove 205 is that circular arc or V-arrangement and described energy-absorbing groove 205 can form by punching press.Thus, form the structure of this energy-absorbing groove by impact style, can reduce industrial manufacturing cost significantly.

According to one embodiment of present invention, as shown in Figure 6, longeron can comprise interior plate 208 and outer panel 209, and the cross-sectional plane of interior plate 208 and outer panel 209 is U-shaped, and the open end of interior plate 208 cooperates and is fixed in the open end of described outer panel 209 so that longeron is configured to hollow tubular.Thus, by the structure of such formation longeron, implement simple in structure, and easy for installation.In addition, at interior plate 208 and the outer panel 209 formation energy-absorbing grooves 205 of U-shaped, cost is cheaper.

According to one embodiment of present invention, as shown in Figure 6, four bights 210 of the cross-sectional plane of longeron are formed with the concave bar 211 towards the internal recess of longeron.Thus, by 210 forming concave bars 211 in four bights in a longitudinal direction at longeron, thereby can realize the absorption to energy in the collision process of back further, and further aggravate longeron in the crumple distortion at energy-absorbing groove 205 places, thereby guarantee the safety of fuel tank 400 further.According to one embodiment of present invention, concave bar 211 can be by forming at this longeron of four bight 210 places punching presses.

Owing to have the longeron 200 of above-mentioned structure, 300 cause, in above-mentioned vehicle frame 100, not only can provide traditional fuel tank protected mode, and can increase for example safety of vehicle fuel tank in the collision process of back of automobile.

As shown in Fig. 7 and Figure 11, in a plurality of crossbeams captive joint with longeron 200,300 rear end respectively in the two ends, the left and right sides of last crossbeam 110.This beam structure with the bumper/spoiler form that the on-fixed of traditional employing is connected is compared, owing to be formed with the cause of endergonic structure on the longeron 200,300, can adopt traditional on-fixed ways of connecting herein, thereby improve the overall construction intensity of vehicle frame 100.

Alternatively, this last crossbeam 110 also can adopt the structure of similar longeron 200, for example this last crossbeam 110 can be fastened by inner and outer plates and form, alleviated the quality of this last crossbeam 110 like this, make vehicle frame lightweight more, this last crossbeam 110 also can act on and pull the crossbeam use simultaneously, preferably, can be provided with brace panel in this last crossbeam 110, can improve rigidity and the intensity of this last crossbeam 110 like this, guarantee in the collision process of back, can fully absorb energy, also guaranteed to pull safety.

As shown in Fig. 1, Fig. 2 and Fig. 7, on the longeron 200,300 formed endergonic structure can with a plurality of crossbeams in backmost crossbeam 110 or and with described crossbeam 110 next-door neighbours' crossbeam 108 adjacent settings backmost.

As shown in Figure 1, also can be provided with spare tyre suspension hook 220 on last crossbeam 110, this spare tyre suspension hook 220 is simple in structure, and suspension hook spare tyre is easily realized spacing to spare tyre.In addition, with described 110 next-door neighbours' of crossbeam backmost crossbeam 108 can be the spare tyre beam, this spare tyre beam can be used for fixedly spare tyre, this spare tyre beam can adopt the single-skin panel structure, can increase integral rigidity and the intensity of vehicle frame so to a certain extent, make vehicle frame lightweight more simultaneously.

Erection support 503 is described below, as Fig. 9, Figure 10 and shown in Figure 11, according to some embodiments of the present invention, erection support 503 comprises absorber seat 504 and spiral spring bearing 505, absorber seat 504 can be integrally welded with spiral spring bearing 505, in other words, absorber seat 504 can be distinguished processing separately with spiral spring bearing 505, and then with the two integrally welded structure.The widget moulding is relatively easy separately, therefore adopts processing absorber seat 504 and spiral spring bearing 505 separately, and then integrally welded mode, can reduce the whole cost of erection support 503.

Certainly, the invention is not restricted to this, in another embodiment of the present invention, absorber seat 504 and the 505 whole processing and manufacturings of spiral spring bearing, for example, absorber seat 504 forms with the casting of spiral spring bearing 505 one, and perhaps absorber seat 504 forms with spiral spring bearing 505 integrated punchings.Can improve the rigidity of absorber seat 504 and spiral spring bearing 505 so better, reduce the probability that absorber seat 504 and spiral spring bearing 505 damage.

In one embodiment of the invention, with reference to shown in Figure 9, the rear and front end of erection support 503 has preceding scrap (bridge) 506 and back scrap (bridge) 507 respectively, the side of the contiguous respective longerons of erection support 503 has welding side (scheming not shown), for example, for the erection support 503 in left side, the left side correspondence of its erection support 503 is provided with the welding side, so that fixing with the longeron 200 of this side.And for the erection support 503 on right side, its right side correspondingly is provided with the welding side, so that fixing with the longeron 300 of this side.
