Description

Air filter

Technical Field

The invention relates to the field of fuel cell vehicles, in particular to an air filter.

Background

The hydrogen fuel cell is a power generation device which directly converts chemical energy generated by the reaction of hydrogen and oxygen into electric energy through electrochemical reaction, has the advantages of high power generation efficiency, small environmental pollution and the like, and is widely applied to the field of automobiles. Due to the characteristics of the fuel cell catalyst and the flow channels, the cathode reaction needs clean and pollution-free oxygen. The air filter is a device for filtering air, and is used for filtering dust, particles and toxic gases in the atmosphere so as to meet the requirements of equipment.

In practical applications, due to the inconsistency of the model and skeleton of the fuel cell vehicle and the arrangement of the fuel cell system, the user needs to adjust the air intake ports to different orientations. However, the air inlet direction of the existing air filter cannot be adjusted generally, or the adjustment is difficult and slow, which wastes manpower and working hours.

The air filter that present automobile-used fuel cell system was used commonly has two types, and what its structure adopted all is the mode that upper and lower casing combines:

fig. 5 shows a schematic diagram of a conventional air filter a. As shown in fig. 5, the air filter a includes an upper casing 201 and a lower casing 202, the upper casing 201 and the lower casing 202 are connected by a snap 203, and the upper casing 201 includes an air inlet 205 and an air outlet 206. The upper shell 201 is designed with a hot melting nut 204, and the air filter can be fixed on the vehicle body by fastening the hot melting nut 204 through a bolt. The disadvantages of air filter a are: the air inlet 205, the upper shell 201 and the hot melting nut 204 are integrated into a whole, and when the air filter is fixedly installed on a vehicle framework, the direction of the air inlet 205 is also fixed and cannot be adjusted. Therefore, the design of the air inlet pipeline is limited when the air filter is used.

Fig. 6 shows a schematic diagram of an existing air filter B. As shown in fig. 6, the air filter B comprises an upper casing 301 and a lower casing 302, which are connected by a snap 303 through the upper casing 301 and the lower casing 302, and the upper casing 301 comprises an air inlet 307 and an air outlet 308. The air filter B is fixed on the frame through two hoops 304, bolts 305 and nuts 306. The disadvantage of the air filter B is that: the orientation of the air inlet 307 is difficult to adjust, and adjustment must be achieved by rotating the hoop 304, and the hoop 304 is a sheet metal part folded by a metal plate, and is difficult to break and rotate. In addition, two staple bolts 304 are independent each other, must guarantee two staple bolts 304 rotation synchronization, just can guarantee that the installation face is on a horizontal plane, but often difficult synchronization in practice needs many times to adjust. A further difficulty is that the locking of the thread pairs requires two wrenches to tighten, one to clamp the bolt 305 and one to tighten the nut 306. It is known from field practice that this adjustment of the air inlet orientation requires 2 persons to be simultaneously engaged.

In view of the above, it would be desirable to provide an air filter that overcomes the deficiencies of the prior art.
