Abstract

The utility model discloses a novel resonant cavity structure, comprising a first housing, a second housing and an air-inlet duct. A clapboard is used to divide the space formed by the first and the second housings into two cavities; the air-inlet duct is used to connect different inserting and connecting ducts inside the two cavities to eliminate noises of different frequencies. The air-inlet duct is divided into two parts welded together, one part is cast with the first housing and the other part is separately cast; the clapboard is cast with the second housing and the first housing is welded and connected with the second housing; sealing strips are adopted to seal the part between the clapboard and the air-inlet duct. By adopting the structure to integrate the two resonant cavities, the novel resonant cavity structure greatly improves the using space of the nose cabin.

Description

A kind of novel cavity resonator structures

Technical field

The utility model belongs to passenger car engine aspirating system performance field, particularly relates to a kind of novel cavity resonator structures.

Background technique

Gas handling system is the important component part of motor, resonant cavity is the parts that are used to eliminate the noise in the gas handling system, for the good resonant cavity of a design, can reduce the induction noise of motor effectively, that improves car load passes through noise level and internal car noise level, NVH (referring to Noise noise, Vibration vibration and Harshness sound vibration roughness, general designation " quality of noise and vibration ") to car load plays significant raising.Passenger car often need increase the peak noise that a plurality of resonant cavitys are used for eliminating different frequency at present.Because the front deck spatial constraints of passenger car, increased very big difficulty for the layout of resonant cavity.

Summary of the invention

In order to address the above problem, the utility model discloses a kind of cavity resonator structures, comprise first housing, second housing and air inlet duct, by a dividing plate first housing is become two-part with the space segmentation that second housing forms, form two chambers, air inlet duct connects different insertion pipes two chamber interior, is used to eliminate the noise of different frequency.

Further, air inlet duct is divided into two-part, and a part is cast together with first housing, another part casts out separately, and two-part weld together, and the dividing plate and second housing are cast as one, first housing and second housing are welded to connect, and seal by Stamping Steel Ribbon between dividing plate and the air inlet duct.

Further comprise support, be used for the fixing of cavity resonator structures.Support by rivet to housing.

By adopting structure of the present utility model, two resonant cavitys are accomplished together, greatly improved the space that utilizes of front deck.

Embodiment

Shown in Figure 1A-1C, the utility model is made an assembly with two resonant cavity centralized arrangement on air inlet duct.Shown in Fig. 2 A, 2B, by a dividing plate 5 whole assembly space segmentation is become two-part, form two chambers, two chamber interior connect different insertion pipes 3,4, are used to eliminate the noise of different frequency.

As shown in Figure 3, for the ease of processing, with the air inlet duct separated into two parts, a part is cast together with first housing 1, another part casts out separately, two-part weld together, to stick on the air inlet duct 6 that casts out separately as the sponge strip that Stamping Steel Ribbon 7 uses then, first insertion pipe 3 and second insertion pipe 2 are cohered on the respective aperture of air inlet duct 6, weld with second housing and the above-mentioned integral body that are cast with dividing plate 5 then, welding back is two chambers of formation resonant cavity independently separately naturally, at last with support 8 by rivet to housing, form last assembly.

Shown in Figure 1A-1C, assembly can be fixed by its support, has improved the compactedness of arranging greatly, has realized the layout of dual resonant cavity in the confined space.
