Embodiment Construction
[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0034] It should be noted that if there is a directional indication (such as up, down, left, right, front, back...) in the embodiment of the present invention, the directional indication is only used to explain the position in a certain posture (as shown in the accompanying drawing). If the specific posture changes, the directional indication will also change accordingly.
[0035] In addition, if there are descriptions involving "first", "second" and ...

The invention discloses an air inlet pipeline and a motor vehicle. The air inlet pipeline comprises a main pipeline, a silencing structure and an adjusting valve. The main pipeline is provided with an air inlet and an air outlet, the main pipeline forms a channel communicating with the air inlet and the air outlet, and the main pipeline is further provided with a first communicating opening and a second communicating opening which communicate with the channel and are sequentially formed in the air inlet direction. The silencing structure is connected with the main pipeline in parallel and provided with a silencing cavity, one end of the silencing cavity communicates with the channel through the first communicating opening, the other end of the silencing cavity communicates with the channel through the second communicating opening, and the adjusting valve is arranged on the silencing structure and located between the first communicating opening and the second communicating opening. The adjusting valve is switched between a closed state and an open state in the process that the air inlet amount is increased or decreased. According to the technical scheme, low-frequency noise reduction is achieved by opening the adjusting valve, or specific-frequency noise reduction is achieved by closing the adjusting valve, so that the problem that an existing air inlet pipeline cannot achieve multi-frequency or multi-frequency-band noise reduction is solved.
Description
technical field [0001] The invention relates to the field of motor vehicles, in particular to an air intake pipeline and a motor vehicle. Background technique [0002] An air intake pipeline is generally provided between the engine supercharger and the air filter of the motor vehicle, and is used to send the air provided by the air filter into the engine supercharger, and the operation of the engine will generate a lot of noise. [0003] The existing air intake is generally arranged between the cab and the cargo box. By adding a resonant cavity, the noise of a single frequency or a single frequency band can be reduced. However, when the engine speed changes, the noise often changes, and the noise reduction frequency point or frequency band cannot be changed. . Contents of the invention [0004] The main purpose of the present invention is to provide an air intake pipeline and a motor vehicle, aiming at solving the problem that the existing air intake pipeline cannot reali...
