But this mode needs sleeve pipe and outside plate welding, and add processing step, during welding, the circular hole of sleeve pipe and inner panel ensures right alignment and the sag of certain precision again, adds the manufacture difficulty of blanked part, improves cost simultaneously.And the more longeron quality that can increase vehicle frame of the amount ratio due to sleeve pipe, the arrangement space of the reinforcement of rail inner affects difficult arrangement by sleeve pipe, and impact easily stressed between sleeve pipe and vehicle frame produces collision abnormal sound.
Utility model content
The purpose of this utility model is to provide a kind of chassis side rail assembly and automobile, the control in longeron cross section is realized by the position limiting structure control inner panel of chassis side rail outside plate and the lap position of outside plate, structure is simple, simplify processing step, reduce manufacturing cost, alleviate the quality of longeron assembly thus realize the lightweight of vehicle.
For achieving the above object, embodiment of the present utility model provides a kind of chassis side rail assembly, comprising:
Side rail and girder plate, described side rail comprises the first relative end face and the second end face, and described girder plate comprises the 3rd relative end face and the 4th end face; Wherein, the upper surface of described first end face is connected with the bottom surface section of described 3rd end face, and the upper surface of described second end face is connected with the bottom surface section of described 4th end face;
Described girder plate also comprises: be symmetricly set in the groove position limiting structure on described 3rd end face and described 4th end face; Wherein,
Described groove position limiting structure comprises the section be separated with described 3rd end face or described 4th end face, and described section abuts the end face edge of corresponding described side rail.
Wherein, described groove position limiting structure is that described girder plate is integrated by Sheet Metal Forming Technology.
Wherein, described groove position limiting structure is bent to form an arc groove by Sheet Metal Forming Technology inside described girder plate.
Wherein, described depth of groove is less than or equal to the thickness of described girder plate.
For achieving the above object, the utility model embodiment also provides a kind of automobile, comprises chassis side rail assembly as above.
The beneficial effect of technique scheme of the present utility model is as follows:
In such scheme, be symmetricly set on the groove position limiting structure on the 3rd end face of girder plate and the 4th end face, the 3rd end face or the 4th end face at section and its place are separated.When inner and outer plates is welded, the end face edge of side rail abuts this section by the restriction of section, like this, the groove position limiting structure combined action restriction side rail on the 3rd end face and the 4th end face and the lap position of side rail, ensure section width when inner and outer plates is welded as longeron assembly.Due to inner fixed sleeving need do not used when welding, decreasing the technological process of this sleeve pipe of welding, simplifying the structure of longeron assembly, reduce manufacturing cost, also reduce the quality of longeron assembly thus realize the lightweight of vehicle.

Detailed description of the invention
For making the technical problems to be solved in the utility model, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model needs the lap position of the limits inner and outer plates by sleeve pipe for existing chassis side rail, complex process, the problems such as manufacture difficulty is large, a kind of chassis side rail assembly is provided, structure is simple, simplify processing step, reduce manufacturing cost, alleviate the quality of longeron assembly thus realize the lightweight of vehicle.
Shown in composition graphs 2, Fig. 3, Fig. 4, the chassis side rail assembly of the utility model embodiment, comprise: side rail 1 and girder plate 2, described side rail 1 comprises the first relative end face 11 and the second end face 12, and described girder plate comprises the 3rd relative end face 21 and the 4th end face 22; Wherein, the upper surface of described first end face 11 is connected with the bottom surface section of described 3rd end face 21, and the upper surface of described second end face 12 is connected with the bottom surface section of described 4th end face 21; Described girder plate 2 also comprises: be symmetricly set in the groove position limiting structure 23 on described 3rd end face 21 and described 4th end face 22; Wherein, described groove position limiting structure 23 comprises the section 231 be separated with described 3rd end face 21 or described 4th end face 22, and described section 231 abuts the end face edge 13 of corresponding described side rail 1.
Can be recognized by foregoing description, be symmetricly set on groove position limiting structure on the 3rd end face 21 and the 4th end face 22 as shown in Figure 3,3rd end face 21 or the 4th end face 22 at section 231 and its place are separated, when inner and outer plates is welded, the end face edge 13 of side rail 1 is subject to the restriction of section 231, abut this section 231, like this, groove position limiting structure combined action restriction side rail on 3rd end face and the 4th end face and the lap position of side rail, ensure section width when inner and outer plates is welded as longeron assembly.Due to inner fixed sleeving need do not used when welding, decreasing the technological process of this sleeve pipe of welding, simplifying the structure of longeron assembly, reduce manufacturing cost, also reduce the quality of longeron assembly thus realize the lightweight of vehicle.
