Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.Should be understood that, detailed description of the invention described herein, only for instruction and explanation of the utility model, is not limited to the utility model.
In the utility model, when not doing contrary explanation, the noun of locality used such as " upper and lower " is that situation about normally using at vehicle is undefined, and the direction that the front and back that " length direction " is vehicle frame extend, " Width, thickness direction " is then perpendicular to length direction.In addition, " inside and outside " refers to the interior and outer of respective objects profile.
As shown in Figures 2 to 6, the utility model provides a kind of stiffening device for strengthening chassis side rail, uses the vehicle frame of this stiffening device and uses the vehicle of this vehicle frame.Wherein this vehicle can be the vehicles such as pick up, body mount support 3 is connected with outside the knee of the chassis side rail 1 of these vehicles, therefore in order to realize the purpose of this utility model, the stiffening device that the utility model provides comprises the distortion be connected to outside knee on the length direction at chassis side rail 1 and hinders support 2, and this distortion hinders support 2 to be formed as box like structure and is formed with the through-hole structure 21 surrounding body mount support 3.
Therefore, by arranging the through-hole structure 21 surrounding body mount support 3, the stiffening device that the utility model provides can not have influence on normal work and the function of body mount support, like this, can the size of support be hindered all can to design larger on length, width and thickness the distortion be connected in the longitudinal direction outside knee, thus by box like structure, the energy after vehicle frame collides is absorbed, effectively promote the stiffening effect to this knee.
It should be noted that, the embodiment that can realize technical solutions of the utility model has multiple, such as distortion hinders the concrete structure and arrangement etc. of support 2, the utility model introduces preferred implementation wherein at this for convenience of description, and this preferred implementation is only not limited to the utility model for illustration of the utility model.
As shown in Fig. 2, Fig. 3 and Fig. 6, in preferred implementation of the present utility model, distortion hinders support 2 side width to be along its length greater than the width of opposite side.This is due on the bearing of trend of chassis side rail 1, its knee can make the size on the Width of chassis side rail 1 different, therefore by part that distortion hinders the larger side of support 2 width to be arranged on knee to inwardly concave, namely, that hinders support 2 to design distortion in the side that knee width is less is wider, to make this knee intensity in the direction of the width roughly the same, like this, energy-absorbing stiffening effect can be strengthened when not taking other car inner regions by the ingenious interior space that utilizes.More preferably, can also the thickness of wider side of support 2 be hindered to design further distortion be greater than the thickness of narrower side.Make the energy-absorbing effect of thicker wider side good like this.
Realizing the different mode of this width has multiple, in preferred implementation of the present utility model, distortion hinders support 2 to comprise main support 22 for connecting vehicle frame longeron 1 and the assistant support 23 that is connected to outside main support 22, this assistant support 23 is positioned at the side that main support 22 is gone up along its length, therefore, it is possible to increase the width of this side, to promote energy-absorbing effect.Wherein more preferably, main support 22 side in the longitudinal direction itself has wider width, and wider side is connected to the side that knee inwardly concaves, to ensure the intensity of curve, then connect this assistant support 23 in this side to ensure the intensity of this side further.In other embodiments, distortion hinders all right as a whole box like structure of support, also should drop in protection domain of the present utility model for this type of mode of texturing.
The stiffening device that the utility model that conveniently producing and assemble the utility model provides provides, preferably, main support 22 and/or assistant support 23 are formed as snapping together and interconnective two halves formula box like structure, such as by welding, then support 2 is being hindered to be welded on chassis side rail 1 this distortion.Wherein " two halves formula structure " described in the utility model refers to that an object comprises interconnective two parts, and these two can be symmetrically arranged also can be asymmetric setting.
Particularly, as shown in Figure 4, main support 22 comprises the first upper bracket 22a and the first lower bracket 22b that snap together, in order to form above-mentioned through-hole structure 2, this through-hole structure 2 comprises the U-shaped breach 21a be formed on the first upper bracket 22a and the via hole 21b be formed on the first lower bracket 22b, wherein U-shaped breach 21a is around the outline of body mount support 3, via hole 21b aligns with the mounting hole 31 of body mount support 3, thus make body mount support 3 be contained between this U-shaped breach 21a and via hole 21b, the use of body mount support 3 can not be had influence on like this, and for which providing spatial accommodation, wherein mounting hole 31 can normally use.Wherein particularly, the first upper bracket 22a can be fastened in the outside of the first lower bracket 22b and its sidewall support is welded to each other, thus makes the Stability Analysis of Structures of main support 22.
As shown in Figure 5, assistant support 23 comprises the second upper bracket 23a and the second lower bracket 23b that snap together, second lower bracket 23b is formed as having the dustpan structure towards main support 22 opening, the first side wall 41 of this dustpan structure is longer than the second relative sidewall 42, and it is outer and be connected with this sidewall that this first side wall 41 extends to the sidewall of main support 22, such as weld, the lower surface that base plate 43 extends to main support 22 is connected with this lower surface, such as weld, second sidewall is supported on main support 22, thus ensure to be connected with the stable of main support 22 by increasing connection area.In addition, the second upper bracket 23a is fastened on and is formed as in the second lower bracket 23b of dustpan structure, and on the upper surface of the second upper bracket 23a, be provided with the flange 44 supporting main support 22.Like this, assistant support 23 can be formed as overall endergonic structure with main support 22, effectively promotes the energy-absorbing stiffening effect of the stiffening device that the utility model provides.Above describe the concrete structure of main support 22 and assistant support 23, in other embodiments, various deformation design can be carried out according to the specification etc. in vehicle body space, knee, this utility model is not limited.
In addition, in order to ensure the strength consistency of the both sides of the vehicle frame that the utility model provides, preferably, two chassis side raiies 1 of vehicle frame are provided with the stiffening device that the utility model provides symmetrically, make vehicle safety high.
To sum up, the technical solution of the utility model make use of interior space dexterously, does not need the use considering body mount support, effectively can strengthen the knee of chassis side rail.In 40% offset collision test, this stiffening device can considerably reduce the deflection in chassis side rail 1 knee, and wheel backward moving resistance increases, and namely decrease the deflection of collision rift crew module, the degree that occupant is hurt alleviates.Therefore, by adopting this offset collision energy absorption device, so that the intensity in chassis side rail knee can be improved widely, there is stronger practicality and promotional value.
Below preferred implementation of the present utility model is described by reference to the accompanying drawings in detail; but; the utility model is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present utility model; can carry out multiple simple variant to the technical solution of the utility model, these simple variant all belong to protection domain of the present utility model.
