Description

Fuel tank
Technical Field
The present invention relates to a resin fuel tank.
Background
As a resin fuel tank, a technique is known in which opposing wall portions are supported by a built-in pillar in the interior of a tank main body. In the fuel tank, the wall portion of the tank body may be deformed outward or inward of the fuel tank due to the internal pressure fluctuation. In this case, if the built-in stay has no stretchability, stress tends to concentrate on the welded portion between the tank main body and the built-in stay, and there is a possibility that cracks may occur in the welded portion and the built-in stay may buckle.
To solve this problem, patent document 1 describes a technique in which an ear lobe shape portion (lobe) which is easily elastically deformed is provided in a built-in stay. Accordingly, when the wall portion of the tank body is deformed to the outside or inside of the fuel tank, the earlobe shape portion is deflected to absorb the deformation amount of the tank body. Thereby, stress concentration at the welded portion is reduced.

Disclosure of Invention
[ problem to be solved by the invention ]
On the other hand, when a portion which is easily elastically deformed is provided locally, there is a problem that rigidity as a strut is easily insufficient, and there is a demand for a built-in strut which combines stretchability and rigidity in a balanced and high-dimensional manner.
[ solution for solving the problems ]
In aspect 1 of the present invention, a fuel tank made of resin includes: a box main body having wall portions facing each other inside; and a built-in stay having both end portions fixed to the opposite wall portions. The internal support column is lattice-shaped in a side view so as to align a plurality of through holes, and the axial direction of the plurality of through holes is orthogonal to the axial direction of the internal support column.
According to the 1 st aspect of the present invention, the internal strut has a honeycomb structure in a side view, and the honeycomb structure has a plurality of through holes arranged adjacent to each other, whereby the rigidity of the internal strut is improved as compared with the case where the site which is easily elastically deformed is provided locally. When the wall portion of the tank main body deforms outward or inward due to the fluctuation of the internal pressure of the tank main body and a force of stretching or compressing in the axial direction is applied to the built-in stay, the periphery of each through hole is deflected in the axial direction by the lattice structure. Thus, according to the built-in pillar of the present invention, stretchability and rigidity can be ensured in a balanced manner, and stress concentration in the welded portion between the tank main body and the built-in pillar can be reduced.
In the 2 nd mode, the through hole is a hexagonal hole, a triangular hole or a circular hole.
According to claim 2, since the lattice shape is formed in the honeycomb shape, both high rigidity and good stretchability of the built-in stay can be achieved.
In the 3 rd aspect, the inner pillar has circular welding surfaces at both ends thereof, the circular welding surfaces being welded to the wall portion, and the inner pillar has a substantially cylindrical shape.
According to the 3 rd aspect, if the internal strut is formed in a substantially cylindrical shape having circular welding surface portions at both ends thereof, the load applied to the welding portion and the internal strut can be uniformly dispersed around the axis. This can reduce excessive concentration of stress on the inner post.
In the 4 th aspect, the number of the built-in struts is 2 or more, and the fuel tank is provided with a connecting portion for connecting adjacent built-in struts.
According to the 4 th aspect, by providing the connection portion for connecting the internal struts, when excessive force is applied to one of the internal struts, the force can be dispersed to the other internal strut through the connection portion.
In the 5 th aspect, the connecting portion is provided at a position away from both end portions of the built-in stay.
According to the 5 th aspect, by providing the connecting portion at the portion having stretchability due to the lattice shape, stress concentration at the connecting portion can be reduced.
In the 6 th aspect, the connecting portion is provided with a plurality of connecting through holes penetrating in the same direction as the through holes and aligned in the axial direction of the built-in stay.
According to the 6 th aspect, the stretchability of the connecting portion itself can be ensured, and the connecting portion can be stretched in accordance with the stretching operation of the built-in stay. This can further reduce stress concentration at the connecting portion.
[ Effect of the invention ]
According to the present invention, the stress concentration at the welded portion between the tank body and the built-in stay during deformation of the tank body is reduced, and therefore the stretchability and rigidity of the built-in stay can be ensured in a balanced manner.

Detailed Description
As shown in fig. 1, the fuel tank 1 includes a built-in pillar 3, and both ends thereof are respectively fixed to wall portions 2A, 2B facing each other inside a resin tank body 2. The layer structure of the tank main body 2 is constituted by, for example, a multilayer cross-sectional structure in which a barrier layer made of a material excellent in fuel impermeability is sandwiched between an inner thermoplastic resin layer forming the inner surface of the tank and an outer thermoplastic resin layer forming the outer surface of the tank. The material of the inner thermoplastic resin layer and the outer thermoplastic resin layer is, for example, PE (high density polyethylene) excellent in hot melt property and moldability. Both ends of the built-in stay 3 are heat-welded to the inner thermoplastic resin layers of the wall portions 2A, 2B.
Referring also to fig. 2 and 3, the internal column 3 has a lattice shape in a side view (P direction orthogonal to the axis O direction of the internal column 3) such that the plurality of through holes 4 are arranged adjacently. The plurality of through holes 4 are also arranged adjacently to each other in a vertical cross section (cross section orthogonal to the axis O direction and the P direction) of the built-in column 3. By forming the internal stay 3 in a lattice shape, the rigidity of the internal stay 3 can be improved as compared with a case where the expansion and contraction portion is provided locally as in the conventional case. Further, for example, when a tensile or compressive force is applied from the wall portions 2A, 2B to the built-in stay 3 in the axis O direction due to the internal pressure fluctuation of the tank main body 2, the lattice wall portion 5 around each through hole 4 is deflected in the axis O direction. Thus, the built-in stay 3 is elastically deformed in the axis O direction without generating excessive stress concentration. That is, according to the built-in pillar 3 of the present invention, stretchability and rigidity can be ensured in a balanced manner, and stress concentration in the welded portion between the tank main body 2 and the built-in pillar 3 can be reduced. In addition, the possibility of buckling of the built-in stay 3 is also reduced by the built-in stay 3 being deflected.
Hereinafter, a preferred embodiment of the built-in pillar 3 will be described.
Embodiment 1
In fig. 1 to 3, the built-in stay 3 includes: a column center portion 6 provided with a through hole 4; and welding surface portions 8 formed at both ends of the column center portion 6 with the column end portions 7 interposed therebetween, and having a substantially cylindrical shape as a whole. The built-in pillar 3 is made of resin, and the pillar center 6, the pillar end 7, and the welding surface 8 are integrally molded.
The through-hole 4 is formed by a hexagonal hole 9. That is, the pillar center 6 of the built-in pillar 3 has a honeycomb structure. The hexagonal holes 9 are arranged in 3 rows extending in the direction of the axis O. The hexagonal holes 9 are arranged in a lattice shape such that a triangle lattice is formed by connecting the centers of the adjacent 3 hexagonal holes 9. When the hexagonal holes 9 are regular hexagons, a line connecting centers of the adjacent 3 hexagonal holes 9 forms a regular triangle lattice. The lattice wall 5 near the peripheral surface of the pillar central portion 6 is formed in a folded flat surface 10, but as shown in fig. 3, the periphery of the opening end of each hexagonal hole 9 is formed in an arc shape so as to extend in the circumferential direction about the axis O, thereby having a substantially cylindrical shape as a whole.
The welding surface portion 8 is formed in a circular plate shape. The welding surface 8 is formed with a plurality of circular arc ribs 12 concentric with the axis O. A plurality of notches are formed in the circular arc rib 12 on the same circumferential line. By providing such a circular arc rib 12, the resin of the tank body 2 surrounds the circular arc rib 12 at the time of thermal welding, and therefore, the weldability between the tank body 2 and the built-in stay 3 can be improved.
According to the present embodiment, the through-holes 4 are formed of the hexagonal holes 9, so that the internal strut 3 has a honeycomb structure, and both high rigidity and good stretchability of the internal strut 3 can be achieved. By forming the inner strut 3 into a substantially cylindrical shape having the circular welding surface portions 8 at both end portions thereof, the load applied to the welding portion and the inner strut 3 can be uniformly dispersed about the axis O. This can reduce excessive concentration of stress on the inner post 3.
Embodiment 2
In embodiment 2, as shown in fig. 4 and 5, 2 built-in struts 3 are connected by a connecting portion 13. Since the structure of each built-in pillar 3 is the same as that of embodiment 1, the description thereof will be omitted. The connecting portion 13 is provided at a position distant from the middle of the built-in pillar 3 at both end portions of the built-in pillar 3, specifically, at the pillar center portion 6. The connection portion 13 is formed of a plate-like portion having a rectangular shape when viewed in the direction of the axis O, which connects the flat surfaces 10 of the respective built-in struts 3 to each other. The plate-like portion is provided in plural at intervals in the axis O direction. Accordingly, the connecting portion 13 is provided with a plurality of hexagonal connecting through holes 14 penetrating in the P direction, which is the same direction as the hexagonal holes 9, and aligned in the axis O direction of the inner strut 3.
By providing the connection portion 13 for connecting the inner struts 3 to each other, when excessive force is applied to one inner strut 3, the force can be dispersed to the other inner strut 3 by the connection portion 13. By providing the connecting portion 13 at a position distant from the middle of the internal strut 3 at both end portions of the internal strut 3, the connecting portion 13 is provided at a portion having stretchability due to the lattice shape, whereby stress concentration at the connecting portion 13 can be reduced. Further, by providing the connecting portion 13 with the plurality of connecting through holes 14 penetrating in the same direction as the hexagonal hole 9 and aligned in the axial line O direction of the built-in pillar 3, the stretchability of the connecting portion 13 itself can be ensured, and the connecting portion 13 can be stretched and contracted in accordance with the stretching operation of the built-in pillar 3. This can further reduce stress concentration around the connecting portion 13.
The preferred embodiments of the present invention have been described above. The through holes 4 are not limited to the hexagonal holes 9, and may be circular holes 15 shown in fig. 6, triangular holes 16 shown in fig. 7, or the like as long as they are arranged in a lattice shape. That is, in the embodiment shown in fig. 6, the circular holes 15 are arranged in a lattice shape such that a regular triangle lattice is formed by connecting the centers of the adjacent 3 circular holes 15. In the embodiment shown in fig. 7, the triangular holes 16 are arranged in a lattice shape such that a hexagonal lattice is formed by connecting the centers of the adjacent 6 triangular holes 16. When the triangular holes 16 are regular triangles, lines connecting centers of the adjacent 6 triangular holes 16 form a regular hexagonal lattice.
In embodiment 2, the number of the built-in struts 3 may be 3 or more.
