[0024] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0025] Reference Figure 1-4 An air intake device fixed on a vehicle body comprises an air filter 1: an air intake pipe 2 is fixedly connected to the outside of the air filter 1, and an installation unit 3 is arranged on the outside of the air intake pipe 2, so that the installation unit 3 is convenient for installing the air intake pipe 2.

[0026] The mounting unit 3 includes a mounting piece 301, which is arranged on the front and rear sides of the intake pipe 2. A limiting piece 302 is arranged on the inner side of the mounting pieces 301 on the front and rear sides. A moving rod 304 is fixedly connected to the outer side of the limiting piece 302. The outer end of the moving rod 304 passes through the mounting piece 301. A spring 305 is fixedly connected between the mounting piece 301 and the limiting piece 302 and located on the outer side of the moving rod 304. A protective plate 306 is fixedly connected to the outer side of the mounting piece 301. A protective block 307 is fixedly connected between the protective plate 306 and the mounting piece 301. A mounting hole 303 is provided on the outer side of the mounting piece 301. Bolts 310 are arranged between the mounting pieces 301 on the front and rear sides. Cover plates 309 are fixedly connected to the front and rear sides of the protective plate 306. The limiting piece 302 is adapted to the intake pipe 2. The moving rod 304 is slidably connected to the mounting piece 301. The protective block 307 is an elliptical The circular structure is set, and the number of moving rods 304, springs 305 and protective blocks 307 are all set in multiples. The protective plate 306 is set in an arc-shaped structure. During installation, the rear mounting plate 301 is installed on the vehicle body, and then the limiting plate 302 on the front mounting plate 301 is used to clamp the intake pipe 2, and then the bolts 310 are used to install the front and rear mounting plates 301 together, so that the front and rear limiting plates 302 can be used to limit the installation of the intake pipe 2. When the intake pipe 2 expands due to heat, the intake pipe 2 squeezes the limiting plate 302 to move, and the limiting plate 302 drives the moving rod 304 to move and squeezes the spring 305 to prevent the intake pipe 2 from expanding due to heat and damaging the clamp and the intake pipe 2. The arc-shaped protective plate 306 and the elliptical protective block 307 can be used to protect the intake pipe 2 inside the limiting plate 302 to prevent the intake pipe 2 from being damaged by external impact force.

[0027] A pressure sensor 308 is fixedly connected to one end of the movable rod 304 close to the protective plate 306. When the intake pipe 2 drives the movable rod 304 to move, the movable rod 304 drives the pressure sensor 308. When the pressure sensor 308 contacts the protective plate 306, the pressure sensor 308 is connected to an external alarm, which activates the alarm to remind people that the internal temperature of the intake pipe 2 is abnormal, so as to facilitate timely maintenance.

[0028] Working principle: When in use, the staff first installs the rear mounting plate 301 on the car body, and then uses the bolts 310 to limit the limit plates 302 on the front and rear sides to limit the intake pipe 2. When the intake pipe 2 expands due to heat, the intake pipe 2 drives the limit plate 302 to move through the limit plate 302, the moving rod 304 and the spring 305, so as to prevent the intake pipe 2 from pressing against the clamp and causing damage to the clamp and the intake pipe 2. The protective plate 306 and the protective block 307 are used to protect the intake pipe 2.

[0029] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
