Specific embodiment
In order to make those skilled in the art more fully understand technical solution of the present invention, below in conjunction with specific embodiment pair
This programme is further discussed in detail.
As shown in Figures 2 to 6, the embodiment of the invention provides a kind of Oiltank structures comprising fuel sucking pipe 22 and is located at
The first partition 23 and second partition 24 of 22 two sides of fuel sucking pipe, headstock of the second partition 24 far from vehicle, first partition 23 and
It is respectively arranged with through-hole 25 on two partitions 24, further includes support 32 and on-off piston, the lower part of second partition 24 is provided with peace
Hole is filled, support 32 is arranged in mounting hole, and support 32 is cylindrical structure, is provided with axial via hole 33 on support 32；On-off is living
Plug includes hollow cylindrical body 42, is arranged on cylindrical body 42 close to the baffle 41 of one end of fuel sucking pipe 22, is arranged in cylindrical body
Annular stop plate 43 on the outer circumference surface of one end on 42 far from fuel sucking pipe 22；Cylindrical body 42 is matched with the axial sliding of via hole 33
It closes；Be provided on the outer circumference surface of one end of fuel sucking pipe 22 on cylindrical body 42 be connected with the centre bore of cylindrical body 42 it is logical
Oilhole 44.It is understood that fuel sucking pipe 22 is mounted on fuel tank shell 21, first partition 23 and second partition 24 and fuel tank shell
Body 21 welds together, headstock of the first partition 23 close to vehicle；On-off piston can be pre-installed in together with support 32；Vehicle
In flat pavement running, oil-through-hole 44 is connected to the cavity where fuel sucking pipe 22, and the oil liquid in the cavity is flowed out；Vehicle
When driving on a graded road surface, under the effect of gravity, the cylindrical body 42 of on-off piston axially via hole 33 to far from vehicle
The direction sliding of head, so that support 32 seals oil-through-hole 44, the cavity where oil-through-hole 44 and fuel sucking pipe 22 separates, and avoids
The outflow of the cavity intermediate fuel oil；As shown in Figure 5 and Figure 6, when vehicle is in flat road surface traveling and the fuel tank in gradient road traveling
The position of pasta B.
Oiltank structure provided in an embodiment of the present invention passes through the cooperation of on-off piston and support 32, can be realized logical oil
The connection and partition of cavity where hole 44 and fuel sucking pipe 22, less in remaining fuel of fuel tank in this way, when vehicle is climbed, on-off is living
The cylindrical body 42 of plug will be slided along axial via hole 33 under the effect of gravity, until baffle 41 connects with 32 phase of support gear, lead to oil at this time
Hole 44 will be located in support 32, so that the cavity where oil-through-hole 44 and fuel sucking pipe 22 separates, avoid appearance where fuel sucking pipe 22
Intracavitary fuel oil outflow, to preferably solve the problems, such as that the fuel sucking pipe occurred in the prior art is inhaled less than fuel oil.
Further, annular mounting plate 31, annular mounting plate 31 and second partition are provided on the outer circumference surface of support 32
24 are detachably connected, so that the connection between support 32 and second partition 24 is relatively firm reliable, and mount and dismount equal
It is more convenient quick.In order to keep the connection between annular mounting plate 31 and support 32 relatively firm reliable, installation behaviour is saved
Make, while convenient for integration production, annular mounting plate 31 can form integral structure with support 32.
As shown in figure 3, annular mounting plate 31 can be connect with second partition 24 by rivet 51.Certainly, annular mounting plate
31 can also be bolted with second partition 24.
In order to keep the wall thickness on the periphery of axial via hole 33 identical, the service life of support 32, axial via hole 33 are improved
The medium position in support 32 can be set, axial via hole 33 can be coaxial with support 32.
Further, support 32 can be obliquely installed with second partition 24, on support 32 close to fuel sucking pipe 22 one end to
Direction far from vehicle body tilts.By this technical solution, can in no gradient and the smaller gradient, oil-through-hole 44 not by every
It is disconnected, guarantee the normal circulation of oil liquid, preferably avoids causing oil-through-hole 44 to be separated because of the impact of oil liquid in no gradient；
When the gradient is larger, oil-through-hole 44 is separated, thus by fuel oil savings in the cavity being connected to fuel sucking pipe 22, to realize combustion
The promotion of fuel tank efficiency, and after vehicle returns flat road surface traveling, additionally it is possible to make on-off piston because this is obliquely installed
Cylindrical body 42 can be slided along axial via hole 33 to the direction by near-car head under the effect of gravity, until annular stop plate 43 and branch
The end face of one end on seat 32 far from headstock, which is mutually kept off, to be connect, and 22 place of oil-through-hole 44 and fuel sucking pipe of on-off piston has been conveniently realized
The connection of cavity, so as to preferably realize the auto switching of oil-through-hole.As shown in figure 4, the tilt angle can be axial
Included angle A between the axis and horizontal line of via hole 33, automobile demand ramp angle when which can be less than or equal to investigation
Half, then when the inclination angle of the gradient is between the angle of zero degree to included angle A, cavity phase of the oil-through-hole 44 where with fuel sucking pipe 22
Connection, when the inclination angle of the gradient is greater than the angle of included angle A, oil-through-hole 44 is separated by support 32, without with where fuel sucking pipe 22
Cavity is connected.
In order to preferably limit and increase the fitting area between baffle 41 and support 32, baffle 41 and support are improved
Leakproofness between 32 reduces a possibility that thus oil liquid enters oil-through-hole 44, and baffle 41 can be cylindrical plate, baffle 41
Diameter is equal to or more than the outer diameter of support 32.Can be preferred, the diameter of baffle 41 is equal to the outer diameter of support 32, so as to more
It saves material and can guarantee the fitting area of baffle 41 Yu support 32.
Specifically, the number of oil-through-hole 44 can be two, and two oil-through-holes 44 are oppositely arranged on cylindrical body 42 close to suction
On the outer circumference surface of one end of oil pipe 22, so as to guarantee vehicle circulation shape of the oil liquid of fuel tank when driving in flat road surface
Condition is good.
A kind of Oiltank structure of the invention erection support 32 and on-off need to only live in the mounting hole of second partition 24
Whether plug, be that plane does not require to tank bottoms structure, facilitate the use of curved surface fuel tank, while being additionally favorable for modularized production.
The above is only the preferred embodiment of the present invention, it should be pointed out that these embodiments are merely to illustrate the present invention
Rather than limit the scope of the invention, moreover, after reading the contents of the present invention, relevant technical staff in the field can be with
Various changes or modification are made to the present invention, such equivalent forms equally fall into model defined by the application the appended claims
It encloses.
