Specific embodiment
It is readily appreciated that, technical solution according to the present utility model, in the case where not changing the utility model in essence spirit, this field
Those skilled in the art can propose the various structures mode and implementation that can be replaced mutually.Therefore, implement in detail below
Mode and attached drawing are only the exemplary illustrations to the technical solution of the utility model, and are not to be construed as the complete of the utility model
Portion or be considered as defines or limits technical solutions of the utility model.
It mentions in the present specification or up, down, left, right, before and after, front, the back side, top, the bottom that may mention etc.
Positional terms are defined relative to each construction shown in the drawings, they are opposite concepts, and it is therefore possible to can root
Correspondingly changed according to different location locating for it, different use states.So also should not be by these or others side
Position term is construed to restricted term.
With reference to Fig. 1 and Fig. 2, the floor side member and torsion of the embodiment according to the present utility model of vehicle bottom are respectively illustrated
The view and decomposition view of cartridge.It should be appreciated that being the view from vehicle bottom in Fig. 1 and Fig. 2, wherein can be inverted
Wheel cover 3 as reference.The floor side member and torsion cartridge of embodiment according to the present utility model include: according to the utility model
Embodiment described in floor side member 1；And the torsion box 2 with the floor side member 1 cooperation.Wherein, floor side member 1 is by more root canal bodies
11,12,13,14 connections are formed.As shown, floor side member is successively by from front to back in specific embodiment of the utility model
The first tube body 11, the second tube body 12, third tube body 13 and 14 4 root canal body of the 4th tube body composition.In an alternative embodiment, after
Stringer 1 can be made of two or three root canal bodies or other any suitable number of tube bodies.
In some embodiments, more root canal bodies 11,12,13,14 are hydraulic tube, i.e., prismatic pipe is in stamping die
Punching press is preforming, is then generally justified by hydraulic device to the cross sectional shape of tube body of the pressurization to be formed in pipe, hydraulic tube
Shape, with lesser occupied space and biggish intensity.In some embodiments, hydraulic tube after shaping can be by quenching
Reason can pass through tempering to improve intensity to eliminate internal stress.In some embodiments, floor side member 1 includes and torsion box 2
The first end of cooperation and opposite second end 10, the second end 10 can be used for connecting with such as sill strip.
