Description

A kind of foam structure for damping

Technical field

The utility model relates to the fields such as foam, electronic product protection, specially a kind of foam structures for damping.

Background technique

As electronic product develops rapidly, also increasingly harsher to its performance requirement, foam product is widely used in Electronic product, it is with EVA that existing foam product, which is mainly common PU foam, hot melt adhesive is pasted together by mold heating Either PF foam is coated with solvent pressure-sensitive adhesive in its one or both sides for substrate and is fabricated again with release paper again, is had close The effect of envelope, bumper and absorbing shock.

Existing foam structure is in damping, after deformation occurs, it is difficult to quickly restore to the original state, if recurring shake Dynamic, then existing foam is difficult to play preferable damping effect.

Utility model content

The purpose of this utility model is: a kind of foam structure for damping is provided, to solve that shape occurs in the prior art After change, it is difficult to which quickly restore to the original state the problem for causing damping effect bad.

Realizing the technical solution of above-mentioned purpose is: a kind of foam structure for damping, including damping base；Multiple foams Item is set between two damping bases；Each foam waviness or S-shaped setting, and two adjacent foams Item is oppositely arranged, and two adjacent foam joints are tangent.

Further, it is equipped in the gap between the foam item and the mutual disjunct foam block of foam item.

Further, the damping groundwork thickness is 0.2mm-1mm.

Further, the foam item is with a thickness of 0.5mm-2mm.

Further, aluminium foil layer is equipped between the foam item and building base.

The utility model has the advantages that: the foam structure for damping of the utility model, good damping effect, vibration and It after deformation occurs, can quickly restore to the original state, structure is simple, easy to use.

Detailed description of the invention

The utility model is further explained with reference to the accompanying drawings and examples.

Fig. 1 is the foam structure schematic diagram of the damping of the utility model embodiment.

Wherein,

1 damping base；2 foam items；3 foam blocks.

Specific embodiment

The explanation of following embodiment is to can be used to the specific reality of implementation to illustrate the utility model with reference to additional schema Apply example.The direction term that the utility model is previously mentioned, such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom" Deng being only the direction with reference to annexed drawings.Therefore, the direction term used be to illustrate and understand the utility model, rather than To limit the utility model.

Embodiment: as shown in Figure 1, a kind of foam structure for damping, including damping base 1, multiple foam items 2 and Foam block 3 and aluminium foil layer.

Damping base 1 uses general material, the base as made of polyester film etc. or polythene material.The present embodiment In, the damping base 1 with a thickness of 0.2mm-1mm, preferably 0.5mm.

Multiple foam items 2 are set between two damping bases；Each 2 waviness of foam item or S-shaped setting, And two adjacent foam items 2 are oppositely arranged, and two adjacent 2 joints of foam item are tangent.Using this structure, work as generation When vibration, foam item is compressed, and is generated deformation, can be generated an interaction force between waveform or the foam item of S-shaped setting, With can be after vibration, fast quick-recovery.

In gap between the foam item be equipped with foam item 2 mutually disjunct foam block 3, to increase the shape of gap Become recovery capability and shockproof effect.The foam item is with a thickness of 0.5mm-2mm.It is equipped between the foam item and building base Aluminium foil layer, electrostatic generates aluminium foil layer in order to prevent.

The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle Within the scope of shield.
