It is to be understood that these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art, in the drawings, the thicknesses of layers and regions are exaggerated for clarity, and the same devices are denoted by the same reference numerals, and thus the description thereof will be omitted.

As shown in fig. 1, the present embodiment provides a vehicle including: a vehicle body and a noise reduction mechanism 20. The vehicle body includes a frame, an engine provided on the frame, and an intake system 10 communicating with the engine. The noise reduction mechanism 20 is disposed at an air inlet of the air intake system 10, the noise reduction mechanism 20 is provided with a plurality of air inlets 21 with different sizes, and air enters the air intake system 10 through the plurality of air inlets 21.

By applying the technical scheme of the embodiment, air or mixed gas enters the air intake system through the plurality of air intake holes 21 with different sizes on the noise reduction mechanism 20. Therefore, when air or mixed gas enters the air inlet system through the air inlet holes 21 with different sizes, the phenomena of mutual disturbance and change of vibration frequency can occur, and the effect of reducing noise is achieved. The technical scheme of this embodiment has solved the great problem of noise of vehicle air intake system among the prior art effectively.

As shown in fig. 1, in the solution of the present embodiment, the noise reduction mechanism 20 includes a noise reduction hood provided at an inlet of the intake system 10. The structure is convenient to process and low in manufacturing cost. Air or mixed gas enters the air inlet system 10 through the plurality of air inlet holes 21 with different sizes on the noise reduction cover, the acting force of the gas on the air inlet holes 21 with different sizes is different, the generated vibration frequency is different, and thus the vibration among the air inlet holes 21 interferes with each other to reduce the amplitude, thereby achieving the purpose of reducing the noise.

As shown in fig. 1, in the solution of this embodiment, the noise reduction cover includes a cylinder and a bottom cover located at a first end of the cylinder, and the plurality of air inlet holes 21 are disposed on the bottom cover. The air inlet holes 21 are convenient to process. Specifically, the intake holes 21 may also be intake passages, i.e., air or a mixture of air flows in the noise reduction cover for a certain time. The air or the mixed gas has different air flow velocities in the air inlet holes 21 with different sizes, so that the acting force and the acting time of the air or the mixed gas on the noise reduction cover are different, and the noise is reduced.

As shown in fig. 1, in the solution of the present embodiment, the noise reduction cover is connected to the air intake system 10 by a snap fit. The noise reduction cover with the structure is convenient to disassemble and assemble, and the disassembling and assembling time is reduced. Of course, the noise reduction hood may also be connected to the air intake system 10 via fasteners.

As shown in fig. 1, in the technical solution of this embodiment, a second end of the cylinder is provided with a fastening structure, and the second end of the cylinder is sleeved on the air intake system 10 and fixed by the fastening structure. When the noise reduction cover is installed, the buckle structure is in an open state, when the barrel is sleeved on the air inlet system 10, the buckle is tightened, and the barrel and the air inlet system are installed on the air inlet system in an interference fit mode. The buckle structure comprises a clamping hook and a clamping ring, the clamping ring is sleeved on the clamping hook, the clamping hook is tensioned by pulling the clamping ring, and then the diameter of the barrel is reduced. Specifically, the second end of the cylinder is provided with a gap at intervals on the circumferential side surface, so that the diameter of the cylinder can be changed.

As shown in fig. 1, in the solution of the present embodiment, the noise reduction mechanism 20 further includes a buffer portion, and the buffer portion is fixed in the cylinder. The provision of the buffer portion further reduces noise. The air or the mixed gas has certain acting force on the buffer part, and the acting force of the air or the mixed gas on the buffer part can be reduced through the deformation of the buffer part, so that the noise is reduced. Specifically, the buffer portion is made of a polyurethane material. The buffering part of the material has good noise reduction effect and lower cost.
