Detailed description of the invention
Fig. 1 is the schematic section for the fuel tank head structure for illustrating a kind of embodiment of the utility model.
Fig. 2 is the schematic isometric for indicating the fuel tank head structure in Fig. 1.
Specific embodiment
Hereinafter, being illustrated referring to attached drawing to the embodiments of the present invention.
Firstly, being said referring to FIG. 1 and FIG. 2 to a kind of fuel tank head structure 100 of embodiment of the utility model
It is bright.Here, the fuel tank head structure 100 is, for example, the top structure of the fuel tank 1 of automobile.
Fuel tank 1 is used to store the fuel oil of internal combustion engine (illustration omitted).As shown in Figure 1, fuel tank 1 is configured to have
The box-like of top surface 11 and bottom surface 12.The fuel tank 1 is configured in the lower section of floor (illustration omitted).The top surface 11 of fuel tank 1 has
There is inclined surface 11a, inclined surface 11a is located at close to the side of vehicle front (positioned at the side in the direction X2).Inclined surface 11a towards
Automobile rear (direction X1) tilts obliquely upward.It is formed in the side at the close automobile rear of top surface 11 and overlooks rounded open
Oral area 13.In the inside of fuel tank 1, it is provided with the fuel delivery for fuel injector (illustration omitted) the supply fuel oil to internal combustion engine
Device 2.
Fuel supply device 2 has pumping section 21, pan portion 22 and interconnecting piece 23.Pumping section 21 is placed in the bottom surface of fuel tank 1
12, for fuel oil to be pumped out supply fuel injector out of fuel tank 1.
Pan portion 22 is configured to overlook rounded, and is configured on opening portion 13, which is blocked.That is, disk
Portion 22 has the function of covering opening portion 13 as lid.Specifically, the peripheral part of pan portion 22 is installed in opening portion 13
On the top surface 11 of surrounding.As shown in Fig. 2, being provided in the pan portion 22, the fuel oil for going out 21 force feed of pumping section is discharged fuel-displaced
Mouthfuls 221, the valve receiving portion 222 of evaporation of fuel valve (illustration omitted) is accommodated and for connecting electric wiring (illustration omitted)
Connector 223 etc..In the case where evaporation of fuel is opened with valve, the evaporation of fuel in fuel tank 1 is discharged to oil tank and (saves sketch map
Show) in.
Interconnecting piece 23 is configured to, and as shown in Figure 1 links pumping section 21 and pan portion 22.In addition, interconnecting piece 23 can be stretched
Contracting, thus in fuel supply device 2, the distance between adjustable pumping section 21 and pan portion 22.
In present embodiment, fuel tank head structure 100 is filled in addition to the opening portion 13 for including fuel tank 1 and fuel delivery
It sets except 2 pan portion 22, further includes the component 3 that keeps out the wind for blocking hot wind for pan portion 22.The component 3 that keeps out the wind is arranged on pan portion
The side of 22 opposite vehicle front, for blocking the hot wind for blowing to pan portion 22 from engine room.
As shown in Fig. 2, the component 3 that keeps out the wind is configured to overlook in semicircular arc, which is configured as, by pan portion
The peripheral part of the side of 22 opposite vehicle front surrounds.In addition, the component 3 that keeps out the wind is configured to, upper end 31 is than lower end 32
Closer to the tilted shape of pan portion 22.In other words, the component 3 that keeps out the wind is configured to, and the radius of curvature of upper end 31 is less than lower end
32 radius of curvature, interarea are gradually (central side of pan portion 22) the inclined ramp shaped inwardly from lower end 32.
The keep out the wind lower end 32 of component 3 is engaged with top surface 11, and the upper end 31 for the component 3 that keeps out the wind is configured in the upper of pan portion 22
Side.Furthermore it is possible to which the component 3 that will keep out the wind is configured to, when in terms of vehicle front, the component 3 that keeps out the wind is covered with front side and the vehicle of pan portion 22
A part of wide direction (Y-direction in Fig. 2) two sides.Alternatively, the component 3 that can also will keep out the wind is configured to, when in terms of vehicle front,
The component 3 that keeps out the wind is covered with the front side of pan portion 22 and all parts of vehicle width direction two sides.
Using above-mentioned fuel tank head structure 100, in running car, along the top surface 11 of fuel tank 1 to automobile rear
The hot wind of the flowing component 3 that kept out the wind before touching pan portion 22 stops.That is, the component 3 that keeps out the wind can make hot blast flow direction pan portion 22
Right and left (Y-direction in Fig. 2) and top.
In present embodiment, as described above, by being arranged for blocking the hot wind for blowing to pan portion 22 from engine room
The component 3 that keeps out the wind, influence of the hot wind to pan portion 22 can be reduced using the component 3 that keeps out the wind, so as to prevent 22 temperature of pan portion from increasing.
In addition, due to keeping out the wind, component 3 is configured to semicircular arc, and is configured as surrounding pan portion in present embodiment
The side of 22 opposite vehicle front, so, hot wind is easy to flow in the lateral direction, so as to more effectively reduce hot wind to disk
The influence in portion 22.
In addition, due to keeping out the wind, component 3 is configured to ramped shaped in present embodiment, so hot wind is easy to flow upwards,
So as to more effectively reduce influence of the hot wind to pan portion 22.
In above embodiment, the various aspects of the utility model are illustrated, but present embodiment not structure
The foundation that pairs of being defined property of the utility model is explained.The technical scope of the utility model is record institute circle of claims
Fixed range cannot be explained only according to above embodiment.In addition, the technical scope of the utility model includes and right
