Description
Technical field
The utility model relates to resonant cavity, especially relates to a kind of modular type tuning variable-volume resonant cavity.
Background technique
In automobile air inlet system development process, need to carry out tuning work, during on-the-spot tuning, need the resonant cavity silencing apparatus applying to various geomery, as Helmholtz resonant cavity, quarter-wave long tube, perforated plate etc.Because resonant cavity generally can only eliminate a single-frequency noise, therefore traditional tuning need of work rule of thumb makes the resonant cavity of various sizes, and cost is comparatively large, and reusing is not high in addition.
Chinese patent CN103629022A discloses a kind of variable frequency helmholtz resonator for automobile air inlet system, comprise all different helmholtz resonator pipeline of helmholtz resonator cavity, two-way sectional area and length and control valve block, helmholtz resonator cavity is connected with the main pipeline of gas handling system by helmholtz resonator pipeline, controls the intersection that valve block is located at two-way helmholtz resonator pipeline; Control by controlling valve block sectional area and the length which helmholtz resonator pipeline communication changes helmholtz resonator pipeline, thus regulate the noise reduction frequency of helmholtz resonator.But this resonant cavity is only by arranging different pipelines, utilize different calibers and length to abate the noise, and pipeline quantity arrange be limited, therefore still well cannot eliminate the noise of different frequency.
Model utility content
The purpose of this utility model be exactly provide to overcome defect that above-mentioned prior art exists a kind of easy to use fast, modular type tuning variable-volume resonant cavity that tunable performance is good.
The purpose of this utility model can be achieved through the following technical solutions:
Modular type tuning variable-volume resonant cavity, is arranged in the suction tude of automotive engine air intake system, the connecting tube comprising cavity and be communicated with cavity, is provided with by the mobile controlling mechanism regulating the cavity volume be communicated with connecting tube in described cavity.
Described controlling mechanism is control piston, and this control piston slides along cavity inner wall.
Described control piston and the joint of cavity inner wall seal through adhesive tape.
Described cavity is provided with volume mark.
Described cavity is provided with bayonet socket, and the end of described connecting tube is provided with the buckle matched with bayonet socket.
Described bayonet socket and buckle place are through rubber belt sealing.
The length of described connecting tube and variable volume.
Compared with prior art, the utility model has the following advantages:
One, fast and easy: can carry out tuning work easily by different connecting tubes and variable-volume resonant cavity, different component reusing is high, quick and convenient and reduce costs.
Two, adjustability is good: the resonant cavity being coordinated variable-volume by modular connecting tube, can each frequency range of covering engine noise, can select the resonant cavity of different frequency of noise elimination when carrying out tuning fast.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1-control piston, 2-cavity, 3-connecting tube.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment
Modular type tuning variable-volume resonant cavity, its structure as shown in Figure 1, mainly be arranged in the suction tude of automotive engine air intake system, the connecting tube 3 comprising cavity 2 and be communicated with cavity 2, be provided with by the mobile controlling mechanism regulating the cavity volume be communicated with connecting tube in cavity 2, in the present embodiment, this controlling mechanism is control piston 1, can slide along the inwall of cavity 2.Control piston 1 seals through adhesive tape with the joint of cavity 2 inwall.Cavity 2 is provided with volume mark, thus the Volume Changes that can conveniently control in resonant cavity carries out noise reduction with coupling to the noise of different frequency.Cavity 2 is provided with bayonet socket, and the end of connecting tube 3 is provided with the buckle matched with bayonet socket, and the joint of bayonet socket and buckle also can through rubber belt sealing.According to different requirements, the length of connecting tube 3 and volume all can change, and only just passable otherwise change the size of buckle, the connecting tube 3 of such different size all can connect with cavity 2.
The utility model is arranged in the suction tude of gas handling system, the volume size that appropriate design cavity 2 is total the size of adjusted volume scope and each connecting tube 3, by regulating the volume of cavity 2 and selecting different connecting tubes, can the noise frequency range that motor is main be eliminated the noise.
