First, the noise problem is mainly the NVH (noise, vibration and harshness Noise, vibration, harshness) problem of the vehicle, and the NVH problem about the vehicle is one of the concerns of various major vehicle manufacturers and parts enterprises in the international automobile industry. Statistics show that about 1/3 of the fault problems of the whole vehicle are related to the NVH problems of the vehicle, and about 20% of research and development cost of each large company is consumed in solving the NVH problems of the vehicle.

In addition, the above-described problem of breakage of the component is mainly that the air cleaner has poor damping performance, and therefore, the air cleaner generates large vibrations in the course of transmitting the excitation force transmitted from the road surface, and the air cleaner may collide with the inner wall of the engine compartment or other components in the vicinity of the air cleaner, thereby causing breakage of the component.

In view of the above, the present application provides a damping device, an air intake system and a vehicle, which aim to solve the problem that the existing air filter has poor damping effect on the exciting force from the road surface, and thus the noise of the whole vehicle is too large.

Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of a damping device according to an embodiment of the present application; FIG. 2 is a schematic cross-sectional view of a mounting post according to an embodiment of the present application, and A-A in FIG. 2 is a cross-sectional line.

The mounting column 1 is connected to the bottom wall of the engine compartment, the mounting column 1 is sleeved with a metal bushing 5 in a sliding manner, and the metal bushing 5 is used for being connected with a supporting foot of an air cleaner so that the metal bushing 5 moves along with the movement of the air cleaner;

the mounting column 1 is provided with a first magnetic piece 2, a second magnetic piece 3 and a third magnetic piece 4 which are sequentially distributed in the height direction, wherein the third magnetic piece 4 is positioned between the first magnetic piece 2 and the second magnetic piece 3; the first magnetic element 2 and the second magnetic element 3 are connected with the mounting column 1, and the third magnetic element is arranged in the metal bushing 5 and moves along with the movement of the metal bushing 5;

Wherein the third magnetic element 4 comprises a first magnetic surface facing the first magnetic element 2 and a second magnetic surface facing the second magnetic element 3, the magnetic pole of the first magnetic surface is the same as the magnetic pole of the first magnetic element 2, and the magnetic pole of the second magnetic surface is the same as the magnetic pole of the second magnetic element 3.

The air filter in the vehicle is located the engine compartment of vehicle, and the air filter plays the effect of filtering dust, sand grain in the air, has the supporting legs on the air filter, and the supporting legs is used for being connected with the diapire in engine compartment, plays the effect of supporting to the air filter. The damping device is arranged on the supporting leg of the air filter, and when the exciting force transmitted from the road surface drives the air filter to vibrate, the damping device can reduce the exciting force to reduce the amplitude of the air filter, so that the damping effect is achieved.

The bottom of the mounting column 1 is fixed with the bottom wall of the engine room, the mounting column 1 is sleeved with a metal bushing 5, the metal bushing 5 can slide on the mounting column 1 along the height direction of the mounting column 1, and meanwhile, the metal bushing 5 is connected with a supporting leg of the air filter, so that when the air filter vibrates along with the excitation force transmitted by the ground, the metal bushing 5 can be driven to slide along the height direction of the mounting column 1.

Referring to fig. 1, an arrow labeled "height direction" in fig. 1 indicates the height direction of the mounting column 1. The air cleaner is mounted in the engine compartment, and the height direction of the mounting post 1 is the same as the height direction of the air cleaner in the engine compartment.

Since the metal bushing 5 slides in the height direction of the mounting post 1 along with the vibration of the air cleaner, the sliding amplitude of the metal bushing 5 in the height direction of the mounting post 1 represents the amplitude of the air cleaner. The air cleaner is connected with the bottom wall of the engine compartment through the supporting legs, and the supporting legs are connected with the metal bush 5, so that the amplitude of the air cleaner is reduced as long as the sliding of the metal bush 5 in the height direction of the mounting column 1 is limited. The limitation of the metal bushing 5 is specifically as follows:

In the present application, by providing the first magnetic member 2, the second magnetic member 3 and the third magnetic member 4, the slip of the metal bushing 5 is restricted by using repulsive force of the same magnetic pole mutual exclusion between magnetic materials, specifically as follows:

The first magnetic pieces 2, the second magnetic pieces 3 and the third magnetic pieces 4 are distributed in the height direction of the mounting column 1, the first magnetic pieces 2, the second magnetic pieces 3 are connected with the mounting column 1, and the third magnetic pieces 4 are located in the metal bushing 5, so that the third magnetic pieces 4 can move along with the movement of the metal bushing 5 at the same time.

Since the same magnetic poles have a mutual repulsive force, when the metal bush 5 moves along the height direction of the mounting post 1, the first magnetic member 2 and the second magnetic member 3 connected to the mounting post 1 apply a repulsive force to the third magnetic member 4 in the metal bush 5, and the closer the metal bush 5 approaches the first magnetic member 2 or the second magnetic member 3, the larger the repulsive force the first magnetic member 2 and the second magnetic member 3 apply to the third magnetic member 4.

When the air filter generates larger amplitude, the metal bushing 5 is driven to move along the height direction of the mounting column 1, and under the repulsive force of the first magnetic piece 2 and the second magnetic piece 3, the amplitude of the air filter is greatly reduced when the metal bushing 5 moves on the mounting column 1, so that the damping effect of the air filter is improved.

By the above arrangement, the metal bush 5 is connected to the air cleaner, and the metal bush 5 can be moved with the movement of the air cleaner. Meanwhile, the first magnetic piece 2 and the second magnetic piece 3 are connected with the mounting column 1, the third magnetic piece 4 is positioned in the metal bushing 5, the third magnetic piece 4 is provided with two magnetic surfaces, namely a first magnetic surface and a second magnetic surface, the first magnetic surface faces the first magnetic piece 2, the second magnetic surface faces the second magnetic piece 3, the magnetic pole of the first magnetic surface is identical to the magnetic pole of the first magnetic piece 2, and the magnetic pole of the second magnetic surface is identical to the magnetic pole of the second magnetic piece 3. The arrangement ensures that when the air cleaner vibrates to drive the metal bushing 5 to vibrate, repulsive force is applied to the metal bushing 5, and the amplitude of the metal bushing 5 is greatly reduced under the influence of the repulsive force, so that the damping effect of the air cleaner is improved, the NVH performance of the whole vehicle is improved, and the damage to the air cleaner or peripheral components thereof caused by overlarge amplitude of the air cleaner is avoided.

With reference to fig. 1 and 2, a specific structure of the mounting post 1 will now be described, with the following arrangements in some embodiments of the application:

Wherein the first magnetic member 2 is connected to the first connecting member 102, and the second magnetic member 3 is connected to the second connecting member 103.

The upright post 101, the first connecting piece 102 and the second connecting piece 103 are combined together to form the mounting column 1, wherein the upright post 101 can be in a strip shape, the first connecting piece 102 and the second connecting piece 103 are positioned at two ends of the upright post 101, and the upright post 101, the first connecting piece 102 and the second connecting piece 103 are connected to form an I-shaped structure.

The first connecting piece 102 is located above the second connecting piece 103, and the first connecting piece 102 and the second connecting piece 103 have opposite sides in the height direction of the upright 101, and the opposite sides are: in fig. 1, the first connecting member 102 and the second connecting member 103 are on opposite sides in the height direction of the column 101.
