Description

Technical Field

[0001] The utility model relates to an automobile catalyst, in particular to a high-efficiency and low-cost packaging structure of a whole-vehicle catalyst. Background Art

[0002] The automobile three-way catalytic converter is the most important external purification device installed in the automobile exhaust system. It can convert harmful gases such as carbon monoxide, nitrogen oxides and hydrocarbons emitted from automobile exhaust into harmless carbon dioxide, water and nitrogen through oxidation and reduction.

[0003] As the automotive industry is impacted by the new energy market, partners closely related to the automotive industry have also been greatly affected. Many automobile companies have launched demands for cost reduction and efficiency improvement, requiring relevant suppliers to implement cost reduction measures and improve efficiency in the areas of cooperation.

[0004] Vehicle testing is an effective measure to test catalyst emissions. When the number of test samples of the same model increases, if a single sample and a single package assembly are used, the packaging cost of the catalyst will increase; due to welding technology limitations, a catalyst package assembly can be modified at most twice, and the catalyst is easily damaged during the modification process. In addition, due to packaging differences between vehicle testing and bench testing, the catalyst needs to be modified back and forth, which is easy to damage the carrier, and the packaging time is long, wasting packaging materials.

[0007] Furthermore, the front cone cover and the rear cone cover have the same shape and are symmetrically installed at two ends of the simple quick-install cylinder.

[0008] Furthermore, the shape of the internal cavity of the simple quick-install cylinder matches the catalytic unit to accommodate and fix the catalytic unit.

[0009] Furthermore, the simple quick-install cylinder is designed as an independent component, which is convenient for disassembly and replacement of the catalytic unit and supports repeated use.

[0010] Furthermore, a gasket is provided between the simple quick-release cylinder and the front cone cover and the rear cone cover, so as to enhance the sealing and connection stability between the front cone cover, the rear cone cover and the simple quick-release cylinder.

[0011] Furthermore, both ends of the simple quick-release cylinder are connected.

[0012] Furthermore, the inner diameter of the internal cavity of the simple quick-install cylinder remains consistent.

[0018] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0019] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] like Figure 1 As shown, a high-efficiency and low-cost whole vehicle catalyst packaging structure includes a front cone cover 1, a simple quick-install cylinder 3, and a rear cone cover 5. The simple quick-install cylinder 3 is a cylindrical hollow cylinder, and the hollow position is the packaging space of the catalytic unit 6. The two ends of the simple quick-install cylinder 3 are provided with plane flanges 2, and are connected to the front cone cover 1 and the rear cone cover 5 through the plane flanges 2. The ends of the front cone cover 1 and the rear cone cover 5 connected to the simple quick-install cylinder 3 are also provided with flange structures that match the plane flanges 2. A gasket 4 is provided between the simple quick-install cylinder 3 and the front cone cover 1 and the rear cone cover 5. The front cone cover 1 and the rear cone cover 5 are of the same shape and are symmetrically installed at the two ends of the simple quick-install cylinder 3.

[0021] The internal cavity of the simple quick-install cylinder 3 is the same shape as the catalytic unit 6. The catalytic unit 6 wrapped with the gasket is pressed into the simple quick-install cylinder 3 through a hydraulic press and a matching cone (the cone is mainly used to facilitate the pressing of the catalytic unit into the cylinder and prevent the wrapped gasket from shifting). The simple quick-install cylinder 3 is an independent component, which is convenient for disassembly and assembly.

[0022] The existing technology mainly requires cutting the original packaging assembly, dissecting the original catalytic unit, and using the tooling mold to complete the sealing of the new catalytic unit by welding. The number of modifications is limited, and the dissection and welding process may damage the catalytic unit. Compared with the existing technology, first, the process of replacing the catalytic unit does not involve cutting and welding, which minimizes the possibility of damage to the catalytic unit; second, the packaging process does not require the opening of a mold, saving the cost and time of opening a mold; third, the packaging is convenient and fast, effectively shortening the packaging time; fourth, the simple cylinder can be reused.

[0023] Taking all the above factors into consideration, a simple packaging structure is adopted to avoid the most difficult EGR connecting pipe and the complex structure of the front and rear cone covers. The main packaging process is as follows:

[0024] (1) Confirm the installation position and spatial layout of the catalyst on the vehicle, confirm the position and size of the flange that needs to be modified, and design the flat flange drawing and the corresponding flange gasket structure;

[0025] (2) Design drawings of simple quick-install cylinders according to the dimensions of the catalytic unit and the catalyst packaging assembly;

[0026] (3) Select suitable materials, cut out accessories according to the drawings, and process them into simple quick-install cylinders and flat flanges;

[0027] (4) The front cone cover, the middle part and the rear cone cover are cut out of the whole vehicle sample. The flat flanges are welded to the cut surfaces of the front and rear cone covers. The three-point positioning method is required to ensure that the bolt holes of the cone cover correspond to each other when the flat flange is installed.

[0028] (5) Weld the flat flange at the connection of the simple quick-install cylinder; seal the catalytic unit into the simple quick-install cylinder, and mark the carrier mark on the surface of the cylinder (the catalytic unit can also be sealed first and then the flat flange is welded);

[0029] (6) The final simple quick-install structure is obtained by combining the modified front and rear cone covers, the simple quick-install cylinder, and the gasket.

[0030] The solution of packaging new catalysts by reusing simple cylinders is that the packaging process only involves packaging the catalysts and pushing the new and old carriers.

[0031] Compared with the original vehicle catalyst structure, this simple packaging structure does not require mold opening during the packaging process, is easy to package, uses less packaging material, and the simple quick-install cylinder can be reused and can be used for whole vehicle and bench tests. It does not need to be re-modified, avoiding damage to the catalytic unit during the modification process.

[0032] The above embodiments describe the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the changes and modifications made by the technicians in this field shall be within the scope of protection of the claims attached to the utility model.
