The joint portion 3 typically has an EVOH hydrocarbon barrier layer 3b.

Description

ATTACHMENT STRUCTURE FOR A COMI'ONENT ll'
A FUEL TANK MADE OF RESIN
The present invention relates to a fuel tank made of resin mounted on an automobile and the like.
Automobile fuel tanks made of resin formed by blow molding have recently become popular due to their advantages of rust-resistance and weight saving.
Usually, attached to the fuel tank are attached various components such as a vent valve for venting the fuel vapour in the space above the liquid surface out of the tank and keeping the pressure inside the tank constant, a check valve connected to a filler tube, and a fuel pump. In the case of a fuel tank made of resin, it is desirable that these components are connected with the tank main body by a thermal iS deposition for the simplification of the manufacturing process.
FIG. 4 is a partial section drawing showing an attachment structure of a component in a conventional fuel tank made of resin. Symbol 24 shows the main body of the fuel tank made of resin; the component 31 is attached to a through hole drilled in a housing wall of the tank main body 24. In FIG. 4 the component 31 is shown as a check valve and is equipped with a joint portion 32 having a flange 36 connected with the outer surface of the tank main body 24, and a tubular valve main body portion 33 provided with a valve mechanism 40 at the top end thereof Upon forming a primary molding portion 37, formed of a material which can be deposited on the tank main body 24, and a hole 39 where a melting resin material is passable, the joint portion 32 has a secondary molding portion 38 consisting of an HC (hydrocarbon) barrier material layer formed by a two-color molding method on a part of an inner periphery of the flange 36 An HC barrier material is generally a non deposition member.
On the other hand, a housing of the valve main body portion 33 is formed of a non deposition member such as POM (Polyoxymethylene, polyacetal resin). The valve main body portion 33 is engaged in the joint portion 32, and an 0-ring 52 is provided at a part of an engagement face thereof. The 0-ring 52 ensures air tightness between the inside and outside of the tank. Usually, a fuel tank is provided with a breather opening (not shown) that acts as an air breather to aid when filling fuel, and it is designed that air breathing within the fuel tank is basically performed only through the breather opening Accordingly, if a gap exists between the joint portion 32 and the valve main body portion 33, there is a possibility of an air leak from the gap; the 0-ring 52 is provided to prevent an air leak.
In the component 3 I, an outside of the flange 36 is formed as the primary molding portion 37, and is connected with the tank main body 24 by a thermal deposition at the outer wall side of the tank main body 24 Because an inside portion of the flange 36 fronting an inside of the tank main body 24 is formed of the secondary molding portion 38 consisting of the HC barrier layer, permeation of HC (hydrocarbon) to an outside of the tank is suppressed by the secondary molding portion 38. The structure thus described is disclosed, for example, in FIG. 1 and paragraph [0022] of Japanese Patent Laid-Open Publication No. 2003 -2074.
In the conventional component 31, portions connecting the joint portion 32 and the valve main body portion 33 are formed by a non deposition member As a result, these portions cannot be connected by a thermal deposition, and therefore the structure is designed so that a gap between them is sealed by the 0-ring 52, upon engaging the valve main body portion 33 in the joint portion 32 as described above.
However, the structure of making the 0-ring 52 intervene causes an increase in the number of components and lowers the build efficiency.
Consequently there is a need for an attachment structure to a fuel tank made of resin which improves the sealing property and satisfies strength, rigidity, and high barrier requirements without the use of a seal member such as an 0-ring.
Viewed from one aspect, the invention provides an attachment structure for a component in a fuel tank made of resin, the structure comprising a resin tank main body, and ajoint portion connected with the tank main body by thermal deposition and supporting an inner tubular member housed in said tank main body, wherein said joint portion and said inner tubular member are formed by an integral molding.
Viewed from another aspect, the invention is an attachment structure for a component of a tank main body made of resin where a connection portion with a tank main body made of resin is formed of a thermally depositable material and which tank main body comprises ajoint portion for connecting to the tank main body by a thermal deposition and an inner tubular member supported by the joint portion and housed in the tank main body, wherein a movement regulation mechanism for regulating movement in the axial direction of the inner tubular member for the joint portion is provided for at least at one of the joint portion and the inner tubular member, where the joint portion and the inner tubular member are formed by an integral molding.
In accordance with the structure, the seal property can be improved and the strength, rigidity, and a high barrier properties can be satisfied without additionally making a seal member such as an 0-ring intervene.
Certain preferred embodiments of the invention will now be described by way of example and with reference to the accompanying drawings, in which.
FIG I is a section drawing showing an outline of an attachment structure for a component of a fuel tank made of resin related to an embodiment of the present invention; FIGS. 2A and 2B are enlargement drawings showing a check valve, as shown in FIG 1; FIG 2A is a section illustration and FIG. 2B is a front view seen from inside the tank, FIGS. 3A and 3B are illustrations related to a second embodiment of the present invention; FIG 3A is a section illustration and FIG. 3B is a front view seen from inside the tank; and FIG. 4 is a partial section illustration showing a conventional attachment structure of a check valve.
In embodiments below, the case will be described of a fuel tank made of resin assumed to be mounted in an automobile and that the attached component is assumed to be a check valve, which is connected to a filler tube for filling oil.
FIG. I is a section drawing showing an outline of an attachment structure of a component (check valve 2) related to an embodiment of the present invention.
FiGS. 2A and 2B are enlargement drawings showing the check valve shown in FIG. 1; FIGS. 2A is a section illustration; and FIG 2B is a front view seen from a tank inside. In these drawings a fuel tank T comprises a tank main body I made of resin for reserving fuel, and attached to a side face of the tank main body I is the check valve 2 for preventing backflow of the fuel The check valve 2 comprises a joint portion 3 attached to an outer peripheral edge portion of a through hole I c formed on the side face of the tank main body 1, and an inner tubular member of a cylindrical form (valve main body portion 4) supported by the joint portion 3 and inserted (housed) inside the tank main body 1 The tank main body 1 is designed to have a section shape where, for example, an BC barrier layer lb consisting of EVOH (ethylene-vinyl alcohol copolymer), which is excellent for the non - permeability of HC (hydrocarbon) and the like, is sandwiched between thermally depositable layers la consisting of a thermally depositable material, such as PE (polyethylene) and the like The joint portion 3 consists of a form having a flange portion 3a attached by a thermal deposition to the outer peripheral edge portion of the through hole ic and a tube connection pipe portion 3c formed toward a tank outside from the flange portion 3a and fitted outside by a filler tube H. The flange portion 3a and the tube connection pipe portion 3c fronting the outside of the tank main body 1 are formed of a thermally depositable material, such as PB (polyethylene) and the like.
The region continuously formed across the face fronting the inside of the tank main body 1, in the flange portion 3a and the inner peripheral face of the tube connection pipe portion 3c, is formed by an HC barrier layer 3b consisting of EVOH (ethylene-vinylalcohol copolymer), which is excellent for non- permeability of BC (hydrocarbon) and the like. The HC barrier layer 3b, the flange portion 3a formed by the PB (polyethylene) and the like, and the region of the tube connection pipe portion 3c fronting the outside of the tank main body I are formed by a two-color molding, and thereby integrally configure the joint portion 3.
The housing for the valve main body portion 4 consists of a form comprising a cylindrical tube middle portion 4a, gradually diminishing in diameter toward the end connected with the joint portion 3, and a valve housing portion 4b for housing a valve mechanism 5. In the embodiment the housing is formed of a non deposition member such as POM (Polyoxymethylene, polyacetal resin) The valve mechanism 5, configured as a backflow prevention mechanism 6 for preventing backflow of fuel into the filler tube H from the tank main body 1, comprises a sliding-in-contact portion 6a and a spring 6b, which are fixed at the valve housing middle portion 4b by a valve fixation portion 7 The valve fixation portion 7 is provided an insertion opening 7a, through which fuel is allowed from inside the tank main body I The present invention is mainly characterized wherein the joint portion 3 connects with the valve main body portion 4, by a movement regulation mechanism for regulating (i e restricting) the movement of the valve main body portion 4 of the joint portion 3 in an axial direction and is provided for at least one of the joint portion 3 and the valve main body portion 4, and that they are formed as an integral molding. As integral molding by a metal mold (specifically an insert molding) is economical, the whole housing of the check valve 2 is integrally formed by inserting POM (Polyoxymethylene, polyacetal resin) for the joint portion 3 formed by a two- color molding The movement regulation mechanism is designed such that an inner peripheral face of a vicinity of an end portion of the tube connection pipe portion 3c there is provided an annular protrusion portion 3e so as to cut into (i.e. protrude into) the outer periphery of the tube middle portion 4a; and a protrusion 4c formed on an outer periphery of the tube middle portion 4a that abuts an end face 3d of the HC barrier material layer 3b fronting the inside of the tank main body 1. Thus, in the valve main body portion 4, movement thereof in the axial direction is surely regulated by the joint portion 3, where the valve main body portion 4 and the joint portion 3 are integrally formed by an insert molding as described above.
In the present invention, as the check valve 2 is integrally manufactured, it becomes unnecessary to build separately and bring together the joint portion 3 and the valve main body portion 4, improving the build efficiency of the whole unit of the fuel tank made of resin. In addition, as the joint portion 3 and the valve main body portion 4 are integrally solidly connected, jolting is reduced, and thus the build accuracy for the tank main body I is improved.
Furthermore, by forming the joint portion 3 and the valve main body portion 4 as an integral molding with a metal mold, specifically by forming them with an insert mold, the seal property between the both is ensured. It becomes unnecessary to make a seal member such as an 0-ring and the like intervene as in the conventional attachment structure of a fuel tank made of resin. Accordingly, as the number of components can be reduced, and as it also becomes unnecessary to utilise an 0-ring and the like, the build efficiency of the whole unit of the fuel tank made of resin is improved in addition, because the seal area can be largely ensured, compared to the case of the 0-ring, the seal performance is improved, compared to that of the conventional attachment structure for a fuel tank made of resin.
A second embodiment of the present invention is herein described. FIGS. 3A and 3B are enlargement section drawings illustrating a second embodiment, where the same symbols are used for the same element as in the first embodiment, and a description thereof is omitted. The second embodiment differs from the first embodiment in the form of the movement regulation mechanism. Whereas the first embodiment is designed such that the annular protrusion 3e is provided so as to cut into (i.e. protrude into) the outer periphery of the tube middle portion 4a at the side of the tube connection pipe portion 3c and to abut the tube connection pipe portion 4c, which is annularly formed at the outer periphery of the tube middle portion 4a, to the end face 3d of the HC barrier material layer 3b fronting the inside of the tank main body 1, the second embodiment is designed such that a claw portion 4d like a hook is formed at the end portion of the tube middle portion 4a of the valve main body portion 4, and that the claw portion 4d is fitted outside the end portion 3f of the HC barrier material layer 3b fronting the inside of the tank main body 1.
Also in accordance with the structure, the movement of the valve main body portion 4 in the axial direction is surely regulated by the joint portion 3, and the joint portion 3 and the valve main body portion 4 are integrally formed by an insert molding. As in accordance with the first embodiment, the seal property between the joint portion 3 and the valve main body portion 4 is ensured, and it becomes unnecessary to make a seal member such as an 0-ring and the like intervene as in the conventional attachment structure of a fuel tank made of resin. Accordingly, as the number of components is reduced, and as it also becomes unnecessary to utilise the 0-ring and the like, the build efficiency of the whole unit of the fuel tank made of resin is improved.
Although the preferred embodiments are described, the present invention is not limited thereto, and appropriate variations are possible without departing from the scope of the invention. For example, although in the embodiments a fuel tank of an automobile is described, the present invention is not limited thereto and, for example, is also applicable to a fuel tank mounted on a ship and the like
