Problems solved by technology
However, due to the complex control and working process of the turbocharger, noise will be generated in many places such as the air intake, while the traditional noise reduction means and noise reduction devices are relatively simple in structure, and the noise reduction effect is poor and cannot be adjusted according to the noise. Change the structure to achieve better noise reduction effect, there is room for improvement

The invention discloses a muffler device and a vehicle. The muffler device comprises an outer shell and a muffling structure. The outer shell is provided with an inlet and an outlet. The muffling structure is disposed in the outer shell, and the muffling structure comprises a resonance tube, a first partition plate and a second partition plate, wherein the first partition plate and the second partition plate are disposed on the resonance tube. The first partition plate and the second partition plate divide the interior of the outer shell into a first expansion cavity, a resonance cavity and asecond expansion cavity, and the resonance cavity is located between the first partition plate and the second partition plate. The first expansion cavity and the second expansion cavity are correspondingly located on the other sides of the first partition plate and the second partition plate, and the first expansion cavity is connected with the inlet and the second expansion cavity is connected with the outlet, wherein the axial relative positions of the first partition plate and the second partition plate are adjustable to change the size of at least one of the resonance cavity, the first expansion cavity and the second expansion cavity. The muffler device can be adjusted automatically to adapt to different muffling frequencies of different vehicles to improve the muffling effect.
Description
technical field [0001] The invention relates to the technical field of vehicles, in particular to a noise reduction device and a vehicle. Background technique [0002] The role of the engine turbocharger is to force more air into the cylinder and mix it with fuel for combustion, which can output greater power than a naturally aspirated engine in the same period of time. However, due to the complex control and working process of the turbocharger, noise will be generated in many places such as the air intake, while the traditional noise reduction means and noise reduction devices are relatively simple in structure, and the noise reduction effect is poor and cannot be adjusted according to the noise. Change the structure to achieve better noise reduction effect, there is room for improvement. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the prior art at least to a certain extent. For this reason, the...
