Abstract
The utility model discloses a reinforced structure of an automobile fuel tank, which comprises a fuel tank (1), an automobile body rear longitudinal beam body (2), a fuel tank front installation point (3) and a fuel tank rear installation point (4). The lateral surface of the fuel tank (1) is connected with the automobile body rear longitudinal beam body (2) by a mounting bracket (5); the fuel tank (1) is movably connected with the mounting bracket (5) which is in spot welding with the automobile body rear longitudinal beam body (2); and the mounting bracket (5) has a semi-cylindrical structure, the lateral surface of the mounting bracket (5) is provided with three flangings (6) and the top of the mounting bracket (5) is provided with a bolt mounting hole (7). The reinforced structure of the automobile fuel tank is provided with the mounting bracket near an area of the fuel tank with weaker rigidity and strength, so that the fuel tank and the automobile body form an organic whole body; and the load born by the fuel tank is reasonably allocated to the automobile body so as to improve the capability of the fuel tank for resisting the deformation, reduce the deformation of the fuel tank body, ensure that the fuel tank structure can completely meet the requirements of rigidity and strength and improve the safe performance of products.
Description
Technical field
The utility model relates to a kind of additional strengthening of fuel tank of vehicle.
Background technology
Find that in test with in feeding back after sale the phenomenon that ftractures often appears in the punching press fuel tank, concrete reason is connected on the vehicle body for the punching press fuel tank by bolt firmly, and attachment point generally is arranged in the fuel tank edge, under the influence of body distortion and fuel tank deadweight, this cognition of fuel tank produces bigger flexural deformation, makes the fuel tank body bear bigger load, under the effect of long-term reverse load, the fuel tank local location can crack, and the leakage of oil problem occurs, has a strong impact on the driving safety of vehicle.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of fuel tank of vehicle additional strengthening at problems of the prior art, its objective is that the load that fuel tank is born reasonably is assigned on the vehicle body, reduces the distortion of fuel tank body.
The technical solution of the utility model is that this fuel tank of vehicle additional strengthening comprises before the fuel tank, vehicle body floor side member body, fuel tank attachment point behind the attachment point and fuel tank, the side of fuel tank is connected with vehicle body floor side member body by mounting bracket,, spot-welded together between mounting bracket and the vehicle body floor side member body between fuel tank and the mounting bracket for flexibly connecting.
The structure of described mounting bracket is a semi-cylindrical shaped, and the side is provided with at least one flange, and the top is provided with bolt mounting holes.
Described fuel tank is connected with bolt mounting holes on the mounting bracket by bolt.
Flange on the described mounting bracket and vehicle body floor side member body are spot-welded together.
Fuel tank of vehicle additional strengthening with above-mentioned special construction has the following advantages:
1, by near the increase mounting bracket more weak zone of fuel tank rigidity and intensity, make fuel tank and vehicle body constitute an organic whole, the load that fuel tank is born reasonably is assigned on the vehicle body, improve the ability of Oiltank structure resistance to deformation, reduce the distortion of fuel tank body, make the fuel tank structure can satisfy the requirement of rigidity and intensity fully, improved the security of products energy.
2, simple in structure, be convenient to the assembling of punch forming and structure, improved manufacturability.
3, actv. has been avoided the big design modification of fuel tank, has saved the expense that design modification produces.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of mounting bracket.
In Fig. 1～2,1: fuel tank; 2: vehicle body floor side member body; 3: attachment point before the fuel tank; 4: attachment point behind the fuel tank; 5: mounting bracket; 6: flange; 7: bolt mounting holes.
The specific embodiment
Figure 1 shows that the structural representation of this fuel tank of vehicle additional strengthening, Figure 2 shows that the structural representation of mounting bracket, by Fig. 1 and Fig. 2 in conjunction with as can be known, this structure comprises fuel tank 1, vehicle body floor side member body 2, fuel tank 1 is provided with before three fuel tanks attachment point 4 behind attachment point 3 and two fuel tanks, the side is connected with vehicle body floor side member body 2 by mounting bracket 5, mounting bracket 5 is a sheet metal component, form by punch forming, the structure of mounting bracket 5 is a semi-cylindrical shaped, the side is provided with three flange 6, the top is provided with a bolt mounting holes 7, flange 6 on the mounting bracket 5 is spot-welded together with vehicle body floor side member body 2, by bolt and bolt mounting holes 7 fuel tank 1 is installed on the support 5 again.
This kind structure makes fuel tank 1 and vehicle body constitute an organic whole, the load that fuel tank is born reasonably is assigned on the vehicle body, improve the ability of Oiltank structure resistance to deformation, reduce the distortion of fuel tank body, make the fuel tank structure can satisfy the requirement of rigidity and intensity fully, improved the security of products energy.
