Abstract
The utility model discloses a rear floor assembly structure for fixing a natural gas cylinder, and aims to provide the rear floor assembly structure with a simple structure and reliable fastness on the basis that the original structure is not changed to the greatest extent. The utility model adopts the technical scheme that the rear floor assembly structure comprises a rear floor and a vehicle frame, wherein a first reinforcing plate is arranged at a joint between a left rear floor rear side member and a rear floor cross beam; another first reinforcing plate is arranged at a joint between a right rear floor rear side member and the rear floor cross beam; positioning nuts are arranged on the first reinforcing plates; concentric holes are formed on the positioning nuts of the first reinforcing plates; two second reinforcing plates adopting n-shaped structures are respectively arranged on the left and the right rear floor rear side members; positioning nuts are arranged at the tops of the second reinforcing plates; and concentric holes are formed on the positioning nuts of the second reinforcing plates.
Description
Technical field
The utility model relates to a kind of vehicle structure, particularly a kind of back floor assembly structure.
Background technology
Along with the continuous development of automotive market and the development and use of new forms of energy, natural gas-powered car is increasing to be rendered in the market.Natural gas-powered car need dispose all very big natural gas bottle of weight and volume on the floor, back; Particularly relatively poor in road conditions, swerve and frequent anxious situation of stopping under; Owing to produce bigger force of inertia, make natural gas bottle in back fixed sturcture on floor and having relatively high expectations of intensity.
The rear floor structure of general automobile is a direct weld bolt on back longitudinal floor beam and crossbeam, and this requirement of strength to the weld is higher, causes that easily insufficient strength forms potential safety hazard, in addition owing to space constraint causes inconvenient installation.
The utility model content
The utility model disposes the problem that natural gas bottle after-burning gas bottle constant intensity can cause potential hazard inadequately to existing natural gas-powered car, and a kind of back floor assembly structure of fixedly natural gas cylinder is provided.This structure is not only changed original structure as far as possible less, the more important thing is that the secure for natural gas bottle provides safety assurance.
In order to realize the foregoing invention purpose; The utility model adopts following technical proposals: a kind of back floor assembly structure of fixedly natural gas cylinder comprises floor, back and vehicle frame; Left back longeron is respectively equipped with first brace panel with the junction of right back longeron in floor, back and back floor crossmember on the floor, back; Said first brace panel is provided with setscrew nut, and the setscrew nut place is provided with concentric hole on said first brace panel; On the right back longeron of left back longeron in floor, back and floor, back, be respectively equipped with " several " font structure second brace panel, the top of said second brace panel is provided with setscrew nut, and the setscrew nut place is provided with concentric hole on said second brace panel.Because the gas cylinder quality is heavier, the constant intensity of floor, back back segment is had relatively high expectations, when after on the beam brace panel being set, increased area of thrust surface, for gas cylinder guarantee is provided fixedly.
As prioritization scheme, on said first brace panel setscrew nut place is set and is provided with heavy stand.Heavy stand plays reinforced rib, has increased the intensity at attachment point place.
As prioritization scheme, the periphery of first brace panel is provided with flange.The area of contact of flange design can the increase brace panel and beam is gained in strength.
As prioritization scheme, be provided with heavy stand at the setscrew nut place on said second brace panel.Heavy stand plays reinforced rib, has increased the intensity at attachment point place.
As prioritization scheme, the side of said second brace panel is provided with flange.Flange increases the area of contact of brace panel and beam.
As prioritization scheme, said back is provided with the installation via hole with said setscrew nut corresponding position on the floor.Via hole is installed on back floor, is convenient to bolt and therefrom passes.
The utility model has increased brace panel on the basis of the least possible change original structure; Simple in structure and vacant too much space; Satisfied the installation requirement of back floor natural gas cylinder installation strength and high-pressure air pipe, for the safety of natural gas-powered car provides further assurance.

Fig. 5 is a kind of scheme drawing of installing and using of the utility model.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is further described.
Like Fig. 1,2,3,4, shown in 5; A kind of back floor assembly structure of fixedly natural gas cylinder; The periphery that the junction of left back longeron 2 and the right back longeron 3 in floor, back and back floor crossmember 4 is welded with triangle first brace panel 5, the first brace panels 5 respectively on the floor, back is provided with flange, and first brace panel is provided with heavy stand; Weld M10 setscrew nut 7 on the heavy stand, and have Φ 11 concentric hole at first brace panel, 6 setscrew nuts, 7 places; On left back longeron 2 in floor, back and the right back longeron 3 in floor, back, weld " several " font structure second brace panel 6 respectively; The side of second brace panel 6 is provided with flange; The top is provided with heavy stand, welding M10 setscrew nut 7 on the heavy stand of top, and setscrew nut 7 places have Φ 11 concentric hole on second brace panel 6.In addition, be provided with the installation via hole with said nut 7 corresponding positions on the floor 1, said back.During installation, at first first brace panel, 5 bottoms and flange are welded on left back longeron 2 in floor, back and the junction of the right back longeron 3 in floor, back with back floor crossmember 4; Bottom and flange with second brace panel 6 is welded on left back longeron 2 in floor, back and the right back longeron 3 in floor, back then; To have the back floor 1 that via hole is installed at last installs.
Support 8 is housed on the natural gas cylinder 9, on the support 8 bolt is housed, bolt position is corresponding with nut 7 positions on the vehicle frame.During installation,, and be positioned on the floor, back at first with the natural gas cylinder mounting bracket, then that each bolts and nuts are corresponding one by one, install and get final product.
The automobile that has a natural gas cylinder in the process of moving; Run into that condition of road surface is relatively poor, emergency brake or when swerving; Because effect of inertia, heavier natural gas cylinder 9 can produce very big force of inertia, adopt this device after; This force of inertia is passed to first brace panel 5 and second brace panel 6 through natural fuels support 8, passes to vehicle frame again.Because first brace panel 5 and second brace panel 6 increase with the area of contact of vehicle frame greatly, make constant intensity increase, and have guaranteed the firm of natural gas cylinder 9, for safe driving provides safeguard.
