Abstract
The utility model proposes a kind of fuel tank with internal partition, comprise fuel oil casing, internal partition, the periphery of internal partition is provided with flange, periphery and the fuel tank intracoelomic cavity cross-sectional plane of internal partition adapt, be respectively equipped with setting circle arc fluting in the corner of the overall flange of internal partition, described setting circle arc fluting is along the thickness direction closed at both ends of internal partition; Internal partition is provided with multiple leakage of oil tapered sleeve, and the length of leakage of oil tapered sleeve is 4-10 millimeter, and the large stomidium footpath of leakage of oil tapered sleeve is 5-12 millimeter, and the hole taper of leakage of oil tapered sleeve is 20-40 °; Two internal partitions are mounted opposite in fuel oil casing, and the small end of leakage of oil tapered sleeve is inside, and inwardly extrude in the lump in the junction, corner of fuel oil casing and internal partition and form rib structure, rib structure is embedded in setting circle arc fluting and fixes internal partition.In the utility model, internal partition is fixing reliable, can not come off because of vibration; When fuel oil casing tilts, fuel oil needs to overcome certain resistance by leakage of oil tapered sleeve, slows down the impulsive force to fuel tank body sidewall.
Description
Technical field
The utility model patent belongs to fuel tank of vehicle field, relates to a kind of fuel tank with internal partition.
Background technology
Fuel tank internal partition is the intensity in order to increase fuel tank, prevents fuel oil big ups and downs.At present, fuel tank internal partition is blanked part, and on fuel tank internal partition, punching processing has multiple oil leaking hole, and oil leaking hole is clear opening, and oil leaking hole length is the thickness of blanked part, only has 0.8-2 millimeter; Be adopt to weld (or spot welding is fixed) fuel tank internal partition on fuel oil casing at production process, there is internal partition obscission in the defect of existence: 1. easily burn body in welding process, welding exists distortion in car running process; 2., because welder's wage is higher, productive costs increases greatly, and welding efficiency is low; 3, in use procedure, when fuel oil casing tilts, fuel oil does not have resistant through oil leaking hole substantially, large to the impulsive force of fuel tank body sidewall.
Summary of the invention
In order to reduce productive costs, avoiding welding deformation, ensureing internal partition reliably fixing on fuel oil casing, slowing down the fuel oil when fuel oil casing tilts and, to the impulsive force of fuel tank body sidewall, the utility model proposes a kind of fuel tank with internal partition.
For this reason, the technical solution of the utility model is: a kind of fuel tank with internal partition, comprises fuel oil casing, internal partition, and the periphery of internal partition is provided with flange, and periphery and the fuel tank intracoelomic cavity cross-sectional plane of internal partition adapt, and it is characterized in that:
Be respectively equipped with setting circle arc fluting in the corner of the overall flange of internal partition, described setting circle arc fluting is along the thickness direction closed at both ends of internal partition;
Internal partition is provided with multiple leakage of oil tapered sleeve, and the length of leakage of oil tapered sleeve is 4-10 millimeter, and the large stomidium footpath of leakage of oil tapered sleeve is 5-12 millimeter, and the hole taper of leakage of oil tapered sleeve is 20-40 °;
Two internal partitions are mounted opposite in fuel oil casing, and the small end of leakage of oil tapered sleeve is inside, and inwardly extrude in the lump in the junction, corner of fuel oil casing and internal partition and form rib structure, rib structure is embedded in setting circle arc fluting and fixes internal partition.
Beneficial effect: the utility model structure is simple, novel, the pressing mode adopting beading to coordinate with setting circle arc fluting fixes internal partition, can not damage fuel tank casing, not have welding deformation, thus can not cause fuel tank leakage of oil; Meanwhile, can ensure internal partition reliably fixing on fuel oil casing, dividing plate also can not come off because of vibration, and productive costs is low; Two internal partitions are mounted opposite in fuel tank, and the small end of leakage of oil tapered sleeve is inside, and when fuel oil casing tilts, fuel oil needs to overcome certain resistance by leakage of oil tapered sleeve, slows down the impulsive force to fuel tank body sidewall.
Accompanying drawing explanation
Fig. 1 is the front view of internal partition in the utility model;
Fig. 2 is A direction view (amplification) in Fig. 1;
Fig. 3 is the lateral plan of internal partition in the utility model;
Fig. 4 is the constructional drawing of a kind of fuel tank with internal partition of the utility model.
Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3 shows, the periphery of internal partition 1 is provided with overall flange 3, periphery and the fuel tank intracoelomic cavity cross-sectional plane of internal partition 1 adapt, and be respectively equipped with setting circle arc fluting 4 in the corner of the overall flange 3 of internal partition, described setting circle arc fluting 4 is along the thickness direction closed at both ends of internal partition; Internal partition is provided with multiple leakage of oil tapered sleeve 2, and the length of leakage of oil tapered sleeve 2 is 4-10 millimeter, and the large stomidium footpath of leakage of oil tapered sleeve 2 is 5-12 millimeter, and the hole taper B of leakage of oil tapered sleeve 2 is 20-40 °.
In technique scheme, the hole taper B of leakage of oil tapered sleeve 2 is preferably 30 °.
As shown in Figure 4, a kind of fuel tank with internal partition, comprise fuel oil casing D, internal partition C, two internal partition C are mounted opposite in fuel oil casing, the small end of leakage of oil tapered sleeve (in Fig. 1 label 2) is inside, fuel oil casing D adopts rib structure, and inwardly extrude in the lump in the junction, corner of fuel oil casing and internal partition and form rib structure, rib structure is embedded in setting circle arc fluting and fixes internal partition C.
