DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] The directional nouns involved in the embodiments of the present application, such as "upper", "lower", "side", etc., are generally represented by Figure 1 The relative relationship of the orientation shown in the figure is used as the basis, and these orientation terms are used only to more clearly describe the relationship between structures, not to describe absolute orientation. When the product is placed in different postures, the orientation may change, for example, "up" and "down" may be interchangeable.

[0037] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those of ordinary skill in the art.

[0038] In order to make the technical solutions and advantages of the present application more clear, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0039] The first aspect of the present application is an air intake structure, such as Figure 1 , Figure 2 and Figure 3 As shown, the air intake structure includes an air intake noise reduction assembly 1, an air intake noise reduction assembly 2, a filter unit 3 and a decorative cover 4, wherein the decorative cover 4 has a resonance cavity 401, and the decorative cover 4 is used to cover the engine 7. The filter unit 3 is connected to the air intake noise reduction assembly 1 and the air intake noise reduction assembly 2. The resonance cavity 401 is connected to the air intake noise reduction assembly 2.

[0040] It is understandable that the air induction noise reduction assembly 1 and the air intake noise reduction assembly 2 can play a role in reducing noise during the process of guiding air by the air intake structure of the present application, so as to reduce the noise generated by the air passing through. The resonance cavity 401 can reduce noise in a certain frequency band, so as to reduce the interference of noise to the user. The resonance cavity 401 is located in the decorative cover 4, which is conducive to improving the space utilization efficiency of the car.

[0041] The bleed air noise reduction assembly 1 can guide air into the filter unit 3 , and then into the intake air noise reduction assembly 2 and the resonance cavity 401 through the filter unit 3 .

[0042] In the embodiment of the present application, the air induction noise reduction assembly 1 can play a noise reduction role in the process of guiding air by the air intake structure of the present application, so as to weaken the noise generated by the air passing through. Among them, the air inhaled from the outside enters the filter unit 3 under the guidance of the air induction noise reduction assembly 1, and the noise generated by the air is initially weakened, so as to help improve the noise weakening effect of the resonance cavity 401. The air induction noise reduction assembly 1 can weaken the noise by consuming part of the kinetic energy of the air, and can weaken the transmission of noise by setting a sound insulation structure.

[0043] In the embodiment of the present application, the air intake noise reduction assembly 2 can play a noise reduction role in the process of guiding air in the air intake structure of the present application, so as to reduce the noise generated by the air passing through. Among them, the air enters the air intake noise reduction assembly 2 through the filter unit 3, which can introduce the air into the engine 7, and further reduce the noise generated by the air to reduce the interference of the noise to the user. The air intake noise reduction assembly 2 can reduce the noise by consuming part of the kinetic energy of the air, and can reduce the transmission of noise by setting a sound insulation structure.

[0044] In the embodiment of the present application, the filter unit 3 may be an air filter.

[0045] In the embodiment of the present application, the decorative cover 4 can hide the resonance cavity 401. When designing the whole vehicle, there is no need to consider the layout space of the resonance cavity 401, which is conducive to improving the space utilization efficiency in the vehicle. Optionally, the decorative cover 4 is made of plastic.

[0046] In the embodiment of the present application, the resonant cavity 401 is connected to the air intake noise reduction assembly 2, so that air can enter the resonant cavity 401 through the air intake noise reduction assembly 2, and can only leave the resonant cavity 401 from the air intake noise reduction assembly 2. During the operation of the air intake structure, air will enter the resonant cavity 401 from the air intake noise reduction assembly 2 until the resonant cavity 401 is filled with air.

[0047] In summary, the air intake structure of the present application reduces noise during the process of guiding air, and uses the decorative cover 4 as a partial structure for noise reduction, thereby improving its space utilization efficiency while reducing noise.

[0048] In some of the embodiments of this application, Figure 1 and Figure 2 As shown, the bleed air noise reduction assembly 1 includes an bleed air section 11 and a first corrugated section 12 , and the first corrugated section 12 connects the bleed air section 11 and the filter unit 3 .

[0049] It is understandable that the air ducting section 11 can guide air into the first corrugated section 12. The inner wall of the first corrugated section 12 is an uneven structure, which can absorb and reflect noise and preliminarily weaken the noise generated by the air, so as to improve the noise weakening effect of the resonance cavity 401.

[0050] In some of the embodiments of this application, Figure 1 and Figure 2 As shown, the air intake noise reduction assembly 2 includes an air intake section 21 and a second corrugated section 22 , the air intake section 21 is connected to the second corrugated section 22 and the filter unit 3 , and the air intake section 21 is connected to the resonance cavity 401 .

[0051] It can be understood that the air intake section 21 is connected to the filter unit 3 and the second corrugated section 22, and can introduce the filtered air into the engine 7 through the second corrugated section 22, and can also introduce part of the air into the resonance cavity 401, so that the resonance cavity 401 can weaken the noise passing through the second corrugated section 22. The second corrugated section 22 can weaken the noise of the air entering the engine 7 by absorbing and reflecting the noise, thereby reducing the interference of the noise to the user.

[0052] In some of the embodiments of this application, Figure 3 As shown, from the side where the air inlet section 21 is located to the opposite side of the side, the cross-section of at least a portion of the resonance cavity 401 has the same shape, and the cross-section of the resonance cavity 401 is a cross-section perpendicular to the direction in which air enters the resonance cavity 401.

[0053] It can be understood that such a configuration is helpful to improve the attenuation effect of the resonance cavity 401 on air noise.

[0054] In some embodiments of the present application, the decorative cover 4 is used to cover the engine 7, and it is necessary to form a stable connection with the engine 7. Figure 1 and Figure 2 As shown, the air intake structure includes a first mounting unit 5 , which is connected to the decorative cover 4 and is located on one side of the decorative cover 4 .

[0055] It can be understood that the first mounting unit 5 is conducive to installing the decorative cover 4 on the engine 7 so that the position between the decorative cover 4 and the engine 7 is relatively fixed. This can, on the one hand, reduce the vibration of the decorative cover 4 when the air enters the resonance cavity 401, thereby reducing the source of noise and reducing the interference of noise to the user. On the other hand, it is also conducive to the decorative cover 4 covering the engine 7.

[0056] In some of the embodiments of this application, Figure 1 and Figure 2 As shown, the first mounting unit 5 includes at least two first tappets 51 , and two of the at least two first tappets 51 are symmetrically arranged with the center line of the decorative cover 4 as the axis of symmetry.

[0057] It can be understood that multiple first struts 51 are conducive to the first mounting unit 5 to form connections between different positions of the decorative cover 4 and different positions of the engine 7, thereby improving the connection performance between the two. At the same time, such a setting is also conducive to avoiding the arrangement position of the first struts 51 being too concentrated, resulting in the problem of vibration of the position on the decorative cover 4 where the first struts 51 are not set due to the air.

[0058] Optionally, all the first tappets 51 are located on the same side of the decorative cover 4 .

[0059] In the embodiment of the present application, a vibration-damping pad may be sleeved on the first tappet 51 , and the vibration-damping pad abuts against the first tappet 51 and the engine 7 respectively to improve the connection stability between the two.

[0060] In some of the embodiments of this application, Figure 1 and Figure 2 As shown, the air intake structure includes a second mounting unit 6 , which is connected to the filter unit 3 and is located at one side of the filter unit 3 .

[0061] It can be understood that the second mounting unit 6 is conducive to installing the filter unit 3 on the engine 7, so that the position between the decorative cover 4 and the engine 7 is relatively fixed. On the one hand, this can reduce the vibration of the decorative cover 4 when the air enters the resonance cavity 401, thereby reducing the source of noise and reducing the interference of noise to the user. On the other hand, it is also beneficial for the decorative cover 4 to cover the engine 7.

[0062] In some of the embodiments of this application, Figure 1 and Figure 2As shown, the second mounting unit 6 includes at least two second tappets, and two of the at least two second tappets are arranged at intervals along the circumference of the filter unit 3 .

[0063] It is understandable that a plurality of second tappets are conducive to connecting different positions of the filter unit 3 and the engine 7, thereby improving the connection performance between the two. The second tappets arranged at intervals along the circumference of the filter unit 3 can be dispersed in multiple positions of the filter unit 3 to support multiple positions of the filter unit 3, thereby improving the connection performance between the two.

[0064] In the embodiment of the present application, a vibration-damping pad may be sleeved on the second tappet, and both the second tappet and the engine 7 are in contact with the vibration-damping pad to improve the connection stability between the two.

[0065] In some of the embodiments of this application, Figure 1 and Figure 2 As shown, the decorative cover 4 and the filter unit 3 are arranged with a gap in the horizontal direction.

[0066] It can be understood that such a configuration is conducive to air passing through the filter unit 3 and entering the decorative cover 4, so that the resonance cavity 401 in the decorative cover 4 weakens the noise of the air, thereby reducing the interference of the noise to the user.

[0067] The second aspect of the present application provides a power system, such as Figure 4 As shown, the power system includes the air intake structure as described in the above embodiment.

[0068] It can be understood that, due to the adoption of the air intake structure of the above-mentioned embodiment, the power system of the present application has the same technical effects as the above-mentioned embodiment, which will not be repeated here.

[0069] In some of the embodiments of this application, Figure 4 As shown, the power system includes an engine 7 , and the decorative cover 4 and the filter unit 3 both cover the engine 7 .

[0070] It can be understood that the decorative cover 4 and the filter unit 3 both cover the engine 7, which is beneficial for the air intake structure of the present application to protect the engine 7, while also improving the space utilization efficiency of the entire vehicle, and is beneficial for designers to arrange other components according to actual needs.

[0071] A third aspect of the present application provides a car, which includes a power system as described in the above embodiment.

[0072] It can be understood that, due to the adoption of the power system of the above embodiment, the automobile of the present application has the same technical effects as the above system, which will not be described in detail here.

[0073] Optionally, the automobile of the present application may be a fuel vehicle or a hybrid vehicle.

[0074] In the present application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance. The term "plurality" refers to two or more than two, unless otherwise clearly defined.
