Abstract

This invention relates to a reinforcement structure made of plastic material for plastic vehicle tank. The reinforcement structure comprises a first portion comprising at least one weak section and at least one strong section, which are designed so that said weak section breaks before said strong section, when said first portion is under mechanical stress, said reinforcement structure also comprises at least one second portion designed to reduce the slosh noise, said second portion extends from the strong section.

First claim

1 . Reinforcement structure made of plastic material for plastic vehicle tank, said reinforcement structure comprising: —a first portion comprising at least one weak section and at least one strong section, which are designed so that said weak section breaks before said strong section when said first portion is under mechanical stress; and —at least one second portion designed to reduce the slosh noise, said second portion extends from said strong section, wherein the first portion and the second portion are made in one piece, preferably by injection-moulding process, wherein the reinforcement structure is design to be welded to an upper base and a lower base of the plastic vehicle tank.

2 . The reinforcement structure according to claim 1 , wherein said weak section is thinner than said strong section.

3 . The reinforcement structure according to claim 1 , wherein the weak section comprises at least one breaking point which is separated from the closest point of the strong section, from which the second portion extends, by a minimal distance.

4 . The reinforcement structure according to claim 3 , wherein said minimal distance is at least 10 mm.

5 . The reinforcement structure according to claim 1 , wherein said reinforcement structure has an axis of revolution and wherein the second portion extends from the strong section in a radial direction.

6 . The reinforcement structure according to claim 1 , wherein the second portion offers a bearing surface of at least 2500 mm 2 .

7 . The reinforcement structure according to claim 1 , wherein the second portion comprises at least one coupling means which are coupled inside a recess comprised in the strong section.

8 . The reinforcement structure according to claim 1 , wherein all said reinforcement structure is made of a thermoplastic material such as thermoplastic polymers including polyethylene, high density polyethylene (HDPE) or fiber reinforced polymer.

9 . The reinforcement structure according to claim 1 , wherein the first portion comprises supporting means in order to ensure support of at least one active component.

10 . The reinforcement structure according to claim 1 , wherein at least one active component is welding on the strong section of first portion.

11 . An assembly composed of a plastic vehicle tank and a reinforcement structure according to claim 1 , wherein the reinforcement structure is welded to an upper base and a lower base of the plastic vehicle tank.

12 . The assembly according to claim 11 , wherein the plastic vehicle tank is a liquid tank for a vehicle.

13 . The assembly according to claim 12 , wherein the plastic vehicle tank is a fuel tank or an additive tank for selective catalytic reduction of NOx.
