Description

Technical Field

[0001] The present invention relates to the field of automotive fuel systems, and particularly to an installation structure for a plastic anti-surge plate of a metal fuel tank. Background Art

[0002] At present, the anti-surge plates of metal fuel tanks on the market are mainly divided into two categories: metal anti-surge plates and plastic anti-surge plates. The metal anti-surge plate is directly welded to the metal fuel tank. The structure is simple and the welding process is mature. However, due to the relatively heavy weight of the metal material, the requirement of lightweight cannot be achieved. At the same time, the price of metal is higher than that of plastic, and the cost has no advantage. The plastic anti-surge plate is generally installed on the metal fuel tank through bolts. A stud is welded inside the metal fuel tank, and the plastic anti-surge plate is provided with a mounting hole to fit the stud, and finally tightened with a nut. This installation structure has high requirements for the design of the plastic anti-surge plate. First of all, the plastic anti-surge plate needs to design multiple stud mounting holes to increase strength, and a strengthening structure needs to be added at the stud mounting hole. The overall design is complex. Secondly, the mold structure is also very complex and cannot be shared for different projects, which has no advantage in terms of development cycle and unit cost. Therefore, we need an installation structure for a plastic anti-surge plate of a metal fuel tank. Summary of the Invention

[0004] In view of this, the object of the present invention is to provide an installation structure for a plastic anti-surge plate of a metal fuel tank to realize the platformization of the installation structure of the metal fuel tank and the plastic anti-surge plate. This greatly simplifies the design of the plastic anti-surge plate. At the same time, the mold design is simple, the production stability is good, the cost is greatly reduced. At the same time, due to the platformization of the installation structure, the development cycle will also be greatly shortened, improving the efficiency.

The end fixing mechanism includes a first docking block fixed to the fixing ring. First clamping blocks are integrally provided on the inner walls of the top and bottom of the first docking block. The end of the plastic wave breakwater is inserted into the first docking block and is snap-fitted with the first clamping blocks.

[0011] Preferably, a clamping groove matching the first clamping block is provided at the end of the plastic wave breakwater, and the first clamping block is clamped in the clamping groove.

[0018] The present invention can not only be used for the installation between the plastic wave baffle and the inner wall of the metal fuel tank, and the installation operation is simple and convenient. Secondly, after installation, the plastic wave baffle can be limited and fixed in all directions, so that it is firm and does not loosen after installation. Secondly, during installation, the distance between the two fixed blocks can be adjusted, so that it can be used to match and install threaded rods with different pitches as needed, and thus the universality of the installation structure is strong and the use effect is good. The whole installation structure is simple and the manufacturing cost is low.

[0019] The present invention can separate the installation structure of the plastic wave baffle from the plastic wave baffle. Different installations of the wave baffle can be shared, and only the wave baffle needs to be re-developed. In this way, the platformization of the product is greatly improved, raw materials are saved, the product development cost and cycle are greatly shortened, and at the same time, the unit price of the product is reduced and the stability of the product is improved.
