Specific embodiment

For technology contents, the construction feature, the objects and the effects that the utility model is described in detail, below in conjunction with implementation Mode simultaneously cooperates attached drawing to be explained in detail.

Embodiment 1

A kind of resilient cushion is disclosed in one embodiment, and the resilient cushion is formed with hollow-out parts, from the upper of resilient cushion Surface to lower surface, resilient cushion include the different section of at least two hollow out accountings, i.e., hollow out accounting has variation.It is signified herein Hollow out accounting, refer on a section, the area of hollow-out part accounts for the ratio of the whole cross section gross area.At least two hollow outs account for Than the different sections, hollow out accounting is in consecutive variations.The different section hollow out accounting of at least two hollow out accountings It is preferably 0~80%, the range that hollow out accounting is covered determines that the resilient cushion can effectively absorb the vibration frequency model of damping Enclose, i.e., the hollow out accounting range is bigger, correspondence can effectively damping vibration frequency range it is also bigger.

Specifically, the hollow-out parts are the hollow hole in resilient cushion, i.e., achieve the purpose that hollow out by forming hole. And preferably it is located at the bellmouth in resilient cushion, and the thickness direction axially along resilient cushion of bellmouth, taper for design Design can be 60 degree.It as shown in Figure 1, Figure 2, Figure 3 shows, include bellmouth 1 in figure, bellmouth is along the section 11 that A-A is formed and cone Shape hole is along another section 12 that B-B is formed.And it can be seen from the figure that different section, it is different to correspond to aperture, hollow out accounting Also it there is difference.From to a certain degree, the aperture of bellmouth is in consecutive variations, to make to cut to a certain extent Face hollow out accounting is also in consecutive variations, therefore can correspond to a continuous fixed frequency, so as to all frequencies in a certain range Vibration all have fabulous absorption damping effect.

In addition, the resilient cushion with a thickness of 0.1mm~300mm.The material of the resilient cushion is elastic material, such as can be excellent It is selected as EVA, rubber, silica gel, polyurethane or foam.

Embodiment 2

A kind of resilient cushion is disclosed in another embodiment, and the resilient cushion is formed with hollow-out parts, from resilient cushion Upper surface to lower surface, resilient cushion include the different section of at least two hollow out accountings.Signified hollow out accounting herein, refers to On one section, the area of hollow-out part accounts for the ratio of the whole cross section gross area.The different section of at least two hollow out accountings, Its hollow out accounting changes in gradient.The change of gradient, gradation levels are at least three-level.

Specifically, the hollow-out parts are the hollow hole in resilient cushion.The hollow-out parts are to be distributed in resilient cushion Circular hole, square hole or irregular hole, the hole depth of circular hole, square hole or irregular hole change in gradient, circular hole, square hole or irregular hole Axially along the thickness direction of resilient cushion.It as shown in Figure 4, Figure 5 and Figure 6, on the way include hole depth different hole 21, hole 22 and hole 33, when along C-C Formation cross-section, corresponding hole 21, hole 22, hole 23 are existed simultaneously on section, and when along D-D Formation cross-section When, hole 22 and hole 23 are only existed simultaneously on section, in this way, just making the hollow out accounting in two sections different.Difference can be passed through Hole depth design, realize the difference of different cross section hollow out accounting, finally can be to different frequencies thus corresponding different intrinsic frequency The vibration of rate, which has, preferably absorbs damping effect.

For mechanical shock, at a certain specific time point, a vibration frequency and waveform or multiple frequencies are often corresponded to The combination of rate and waveform, and the frequency and waveform may also therewith the time variation and change or constant.This vibration It often gradually hands on, causes other materials with the vibration of certain frequency.It should shake itself, often there is a spy Determine frequency and waveform can effectively weaken or fully absorb in this and shakes.Conventional resilient cushion due to intrinsic frequency limitation, it is past It is past only to have good weakening or assimilation effect to the vibration of a certain specific frequency and waveform.And subtracting in the utility model Shake pad, founding property pair cross-section carry out the designs of different hollow out accountings, allow to cope with multiple frequencies and waveform or combinations thereof. I.e. when the resilient cushion in use, a certain mechanical shock is conducted to above it and to its lower surface further transmits, since section is engraved The variation of empty accounting, even therefore the vibration of different frequency, all always can on a certain section with a certain hollow out accounting quilt Effectively weakens or fully absorb.All there is splendid damping effect so as to the vibration to optional frequency in range and waveform.
