Description

A kind of reinforced plastics intake manifold
Technical field
The utility model relates to a kind of automotive engine component, particularly relates to a kind of engine intake manifold structure.
Background technique
Engine intake manifold is its function of vitals of motor car engine is that air, fuel mixture are assigned to each cylinder intake duct by Carburetor or throttle body.When motor car engine works, intake manifold can send larger noise, is also one of Main Noise Sources of motor car engine noise.Trace it to its cause, because in the process of motor interval air inlet, intermittent generation negative pressure in intake manifold, intermittence causes the deformation of intake manifold upper surface, make intake manifold resonant cavity obvious away from the middle part local vibrations of the end face of manifold port, in the full speed range of motor, easily occur resonance and local Breathing mode.Adopt in prior art and strengthen compartment sound insulation technology and material, this part noise is isolated.But this kind of technological scheme is not improved this noise source of intake manifold, cause noise reducing effect comparatively limited.
Model utility content
The utility model is that the local vibrations in order to overcome its upper surface middle part of intake manifold of the prior art is obvious, resonance and local Breathing mode is easily there is in the full speed range of motor, produce the deficiency of larger noise, provide a kind of reinforced plastics intake manifold effectively reducing intake manifold noise.
For achieving the above object, the utility model is by the following technical solutions:
A kind of reinforced plastics intake manifold of the present utility model, comprise a tube shell resonant cavity housing, the shell wall thickness of resonant cavity housing end face is increased to middle part gradually by edge, and be provided with hexagonal depression of honeycomb-shaped structure distribution at the outer surface of resonant cavity housing end face, the honeycomb-shaped structure surface that described depression is formed is equipped with sound-absorbing pad, described sound-absorbing pad is provided with towards a side of resonant cavity housing the Hexagon boss coordinating honeycomb-shaped structure, fold is arranged at intervals with along adjacent lands, the height on the relative sound-absorbing pad surface of described boss end face is less than the degree of depth of depression.
The structure that in the utility model, the thickness of resonant cavity housing end face is increased gradually by edge to middle part and the sunk structure of resonant cavity housing outer surface, add the structural strength of resonant cavity end face, improve the Breathing mode of intake manifold housing at this place, avoid occurring resonance phenomenon in the full speed range of motor, reduce intake manifold noise with this from root.The sound-absorbing pad being laid on honeycomb-shaped structure surface further enhancing the noise reduction for resonant cavity case top.Boss not only increases the cooperation fastness of sound-absorbing pad and honeycomb-shaped structure, and adds the local thickness of sound-absorbing pad in honeycomb-shaped structure inside, and booster injection is to the absorbing sound and lowering noise effect of this part targetedly.Fold strengthens sound-absorbing pad has any local elongation deformation nature at boss edge, and boss end face resonant cavity surface of shell leaves gap, when ensureing intake manifold work, sound-absorbing pad does not remain laminating depression by the interference of resonant cavity shell vibrating and micro-deformation, change the natural frequency of partial structurtes simultaneously, avoid the resonance phenomenon in running, ensure absorbing sound and lowering noise effect.
As preferably, the thickness in the middle part of resonant cavity housing end face is 1.5 ~ 2 times of edge thickness.
As preferably, recessed hexagonal structure width is 2.5 ~ 3.5 times of cup depth.
As preferably, sound-absorbing pad uses butyl material.
Therefore, the utility model has following beneficial effect: (1) improves the local Breathing mode of resonant cavity housing; (2) sound-absorbing pad absorbing sound and lowering noise; (3) resonance phenomenon in running is avoided.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model props up tube shell resonant cavity housing.
Fig. 2 is partial schematic sectional view of the present utility model.
In figure: 1 tube shell; 2 resonant cavity housings; 3 depressions; 4 sound-absorbing pads; 5 boss; 6 folds.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done into a cloth description.
Embodiment: as shown in Figure 1 and Figure 2, a kind of reinforced plastics intake manifold of the present utility model comprises a tube shell 1 resonant cavity housing 2.
The shell wall thickness of resonant cavity housing 2 end face is increased to middle part gradually by edge, and the thickness in the middle part of resonant cavity housing 2 end face is 1.5 times of edge thickness.
The outer surface of resonant cavity housing 2 end face is provided with hexagonal depression 3 of honeycomb-shaped structure distribution, and the 3 hexagonal structure width that cave in are 3 times of depression 3 degree of depth.
Depression 3 structure of the structure that the thickness of resonant cavity housing 2 end face is increased gradually by edge to middle part and resonant cavity housing 2 outer surface, add the structural strength of resonant cavity end face, improve the Breathing mode of intake manifold housing at this place, avoid occurring resonance phenomenon in the full speed range of motor, reduce intake manifold noise with this from root.
The honeycomb-shaped structure surface that depression 3 is formed is equipped with sound-absorbing pad 4, and sound-absorbing pad 4 uses butyl material.Described sound-absorbing pad 4 is provided with the Hexagon boss 5 coordinating honeycomb-shaped structure towards a side of resonant cavity housing 2, be arranged at intervals with fold 6 along adjacent lands 5, and the height on described boss 5 end face relative sound-absorbing pad 4 surface is less than the degree of depth of depression 3.
The sound-absorbing pad 4 being laid on honeycomb-shaped structure surface further enhancing the noise reduction for resonant cavity housing 2 top.Boss 5 not only increases the cooperation fastness of sound-absorbing pad 4 and honeycomb-shaped structure, and adds the local thickness of sound-absorbing pad 4 in honeycomb-shaped structure inside, and booster injection is to the absorbing sound and lowering noise effect of this part targetedly.Fold 6 strengthens sound-absorbing pad 4 has any local elongation deformation nature at boss 5 edge, and gap is left on boss 5 end face resonant cavity housing 2 surface, when ensureing intake manifold work, sound-absorbing pad 4 does not shake by resonant cavity housing 2 and the interference of micro-deformation remains laminating depression 3, change the natural frequency of partial structurtes simultaneously, avoid the resonance phenomenon in running, ensure absorbing sound and lowering noise effect.
