Description

Technical Field

[0001] The utility model relates to the technical field of all-terrain vehicles, in particular to a lifting air intake pipe and a tracked amphibious all-terrain vehicle. Background Art

[0002] The existing engine air intakes of amphibious all-terrain vehicles are relatively low. When driving on the sea, if there are strong winds and waves at sea, seawater will be poured into the engine air intake from the air intake, causing the engine to stall or even cause certain damage to the engine, posing a great safety hazard. The intake pipe structure disclosed in the comparative document "CN220081563U-An intake pipe for an all-terrain vehicle" is similar to the technical field and technical issues of the present application. It is easy to disassemble and assemble while improving the connection stability between the filter sleeve and the intake pipe body. However, if seawater is prevented from entering the engine only by raising the intake pipe, not only will the appearance of the entire vehicle be inconsistent, but it will also cause the vehicle to be too high when it is transported on the road. The utility model provides a lifting intake pipe, which solves the lifting problem of the engine intake pipe and is adapted to the amphibious and land transportation conditions of amphibious all-terrain vehicles. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a lifting air intake pipe and a tracked amphibious all-terrain vehicle.

[0004] The technical solution of the utility model is:

[0005] A lifting air intake pipe comprises: a rain cap, a sleeve, a push rod and an air intake pipe base, wherein the rain cap is mounted on the top of the sleeve, the cylinder rod of the push rod is mounted on the sleeve, and the push rod cylinder base is mounted on the air intake pipe base.

[0006] A push rod mounting seat is also arranged on the upper end surface of the sleeve, and the top of the cylinder rod of the push rod is mounted on the push rod mounting seat.

[0007] A push rod mounting seat is arranged at the bottom of the air intake pipe base; and the push rod cylinder body base is mounted on the push rod mounting seat.

[0008] A push rod limiting ring is arranged on the upper end of the air intake pipe base.

[0009] A first rubber sleeve for limiting the push rod is arranged on the air intake pipe base.

[0010] The casing is provided with a second rubber sleeve for sealing the bottom of the casing.

[0011] The utility model also provides a tracked amphibious all-terrain vehicle, which has the above-mentioned lifting air intake pipe, and the lifting air intake pipe is welded to the vehicle body through the air intake pipe base.

[0012] The function of the rain cap is to prevent rainwater and waves from entering the exhaust pipe; the function of the push rod limit ring is to fix the push rod cylinder to prevent the cylinder from being eccentric and causing excessive force to damage the push rod when it is extended; the function of the rubber sleeve on the inner side of the bottom of the sleeve is to limit the extension of the push rod; the function of the rubber sleeve set on the outside of the intake pipe base is to seal and prevent water from penetrating into the intake pipe from the bottom of the sleeve.

[0013] The utility model also provides a tracked amphibious all-terrain vehicle, which has the above-mentioned lifting air intake pipe.

[0014] When the amphibious all-terrain vehicle is traveling on the sea, the air intake pipe is raised by extending the push rod to meet the sea conditions required for traveling on the sea. When traveling or transporting on land, the air intake pipe is lowered by shortening the push rod to meet the requirements for traveling on land.

[0015] The beneficial effects of the utility model are:

[0016] The structure of an electric, starting or hydraulic push rod passing through a sleeve and a base is adopted to meet the requirements of lifting and lowering the intake pipe. At the same time, a limit ring is added to the intake pipe base to prevent the push rod from eccentricity and damaging the push rod and the intake pipe. At the same time, a limit and sealing sleeve is added to meet the limit and intake pipe sealing requirements.

[0017] The utility model solves the problem that when an amphibious all-terrain vehicle is traveling in level three sea conditions (wave height: 0.5-1.25 meters), seawater enters the engine through the air inlet, causing the engine to stall and be damaged; and solves the transportation problem caused by the vehicle being too high due to a relatively high air inlet pipe.
