This utility model provides a kind of side bar, and it forms L-type structure by vertical strutbeam with horizontal strutbeam, for crossbeam Install and provide convenient, improve it and fixing fastness is installed, meanwhile, alleviate again the weight of side bar self.

As shown in Figure 1, Figure 2 and Figure 3, wherein, Fig. 1 is the structural representation of side bar of the present utility model.Fig. 2 is in Fig. 1 The structural representation of side bar cross section.Fig. 3 is the structural representation that side bar of the present utility model is installed on body of a motor car.

In a kind of specific embodiment, this utility model provides a kind of side bar 10, including:

Vertically strutbeam 11, this vertical strutbeam 11 extends along the length direction of vehicle body；With

Horizontal strutbeam 12, this horizontal strutbeam 12 the most also extends along the length direction of vehicle body, and, this horizontal strutbeam 12 is certainly Vertically the medial surface of strutbeam 11 bottom, extend along the width of vehicle body towards the inner side of vertical strutbeam 11.

As depicted in figs. 1 and 2, horizontal strutbeam 12 is connected the side bar 10 forming the L-shaped setting of end face with vertical strutbeam 11, its At grade, and the end face of its end face and vertical strutbeam 11 has in the bottom surface of the bottom surface of horizontal strutbeam 12 and vertical strutbeam 11 Certain distance；It is to say, vertically there is certain gradient between strutbeam 11 and horizontal strutbeam 12 end face, thus can be used for pre-determined bit Crossbeam 20, and also improve the rigidity of side bar 10 self.

Shown in Fig. 3, the medial surface of the vertical strutbeam 11 of this side bar 10 is connected with crossbeam 20 end face of automobile, lateral surface It is connected with the support of automobile；And the horizontal upper side of strutbeam 12 is connected with the downside of crossbeam 20 end of automobile, with location Support crossbeam 20.When actual installation crossbeam 20, utilize the structure of above-mentioned side bar 10, the end of crossbeam 20 is first overlapped in level and props up The upper side of beam 12, and make its end face support the medial surface being affixed on vertical strutbeam 11；After completing location and installation, then by crossbeam 20 with perpendicular Allotment beam 11, horizontal strutbeam 12 position bonded to each other is welded and fixed.In compared to existing technology, the level of this side bar 10 is propped up Beam 12 not only can carry out pre-determined bit installation to crossbeam 20, accurately fixes providing safeguard, also by vertical strutbeam 11 and level for it The binding face of strutbeam 12 carries out dual being welded and fixed, and is greatly improved the fixing fastness of crossbeam 20 by improving contact area.

Wherein, in the present embodiment the side bar 10 of indication can be in body frame optional position with crossbeam, there is annexation Longeron, it can provide for crossbeam and position accurately, and stable support is fixed.

Compared with structure of the prior art, the side bar 10 of said structure is while satisfied installation fixed cross beam 20, also Alleviate the weight of side bar 10.

It is understood that the side bar 10 of the present embodiment is arranged in vehicle body, inner side the most alleged With outside it is all on the basis of the width of vehicle body, i.e. outside is towards body exterior on the width of vehicle body Side, inner side is the side on the width of vehicle body towards interior of body.Similarly, the upper side and lower side is all with vehicle body On the basis of short transverse, i.e. upside is the side towards roof direction, downside is the side towards underbody direction.

This side bar 10 uses aluminium alloy extrusions extruding to be formed, and manufacturing process is simple, it is easy to molding.Further, in conjunction with above-mentioned limit Beam 10 structure, uses aluminium alloy to further mitigate the weight of side bar 10.

Further, side bar 10 is optimized design, shown in Fig. 1 and Fig. 2.

Vertically there is in strutbeam 11 first cavity 111 of the length direction extension along vehicle body, and horizontal strutbeam 12 has edge The second cavity 121 that the length direction of vehicle body extends, hollow-core construction can alleviate the weight of side bar 10, can absorb again part The impact force that side impact produces, improves vehicle body security performance.

For first cavity the 111, second cavity 121 along the cross sectional shape of vehicle-body width direction, it is preferable that be disposed as square Shape.On the one hand it is easy to processing, low cost, on the other hand, it is possible to the intensity of lifting side bar 10 carrying support crossbeam 20, also can resist The intensity of collision.Certainly, first cavity the 111, second cavity 121 can be also other shape along the cross sectional shape of vehicle-body width direction Shape, sets according to rigidity, the requirement of strength of vehicle body reality.

Side bar 10 also includes reinforcement 13, and this reinforcement 13 is arranged vertically at the first cavity 111 and the second cavity The junction of 121.As in figure 2 it is shown, in this specific embodiment, reinforcement 13 is interior with the first cavity 111 of vertical strutbeam 11 Side plate is in same perpendicular, so, this reinforcement 13 and vertical strutbeam 11, horizontal strutbeam 12 can be made to be processed to form one knot The side bar 10 of structure, reduces processing cost；And the rigidity of side bar 10 self can be increased, improve the second cavity 121 and resist side impact With the intensity supporting crossbeam 20.

For the various embodiments described above, the size that its horizontal strutbeam 12 extends along the width of vehicle body towards vertical strutbeam 11 In the range of 18mm～20mm, the width dimensions of the most horizontal strutbeam 12 can in the range of 18mm～20mm, can be such as 18mm, 19mm, 19.5mm or 20mm etc., the width dimensions of horizontal strutbeam 12 in this range can while lightweight side bar 10, for Support, welding beam 20 provides and is fully contacted area.

In a particular embodiment, as in figure 2 it is shown, the size of preferred side bar 10 is: the total chi extended along bodywork height direction Very little for 70mm, the overall size extended along vehicle-body width direction is 60mm, and the first cavity 111 with the wall thickness of the second cavity 121 is 3mm；The most horizontal strutbeam 12 is 20mm along the optimal size that vehicle-body width direction extends, the optimum extended along bodywork height direction A size of 15mm, so, it is possible fully providing itself and crossbeam 20 bonding area, and meets the installation requirement premise of M8 bolt Under, farthest alleviate the weight of side bar 10.

It should be noted that the restriction in the above-mentioned parameter of side bar 10 mathematics of non-critical and/or geometry meaning, also Comprise it will be appreciated by those skilled in the art that and the error of the permission such as manufacture or use.

In addition to above-mentioned side bar 10, this utility model also provides for a kind of automobile, and the side bar 10 in above-described embodiment is applied to On this automobile.The annexation of side bar 10 and automobile can be found in above-mentioned specific embodiment and prior art, and other of this automobile Structure and annexation are please also refer to prior art.Owing to above-mentioned side bar 10 has above technique effect, therefore, apply this limit The automobile of beam 10 should also be as having identical technique effect, does not repeats them here.

It is to be understood that, although this specification describes according to each embodiment, but the most each embodiment only wraps Containing an independent technical scheme, this narrating mode of description is only that for clarity sake those skilled in the art should Description can also be formed people in the art through appropriately combined as an entirety, the technical scheme in each embodiment Member may be appreciated other embodiments.

The a series of detailed description of those listed above is only for the tool of feasibility embodiment of the present utility model Body illustrates, and and be not used to limit protection domain of the present utility model, all without departing from this utility model skill spirit made etc. Effect embodiment or change, as feature combination, split or repeat, within should be included in protection domain of the present utility model.
