Elastomer structure

Abstract

The invention relates to an elastomer structure which is combined with an inner retaining body, an outer retaining body and an actuating elastomer. The inner retaining body and the outer retaining body are provided with holding spaces and retaining edges on the inside of a pressed surface; the actuating elastomer is arranged in the holding spaces of the inner retaining body and the outer retaining body; a pressure releasing part is arranged between the pressure resisting surfaces of an inner edge end and an outer edge end; the pressure releasing part provides the compressed actuating spaces for the inner retaining body, the outer retaining body and the actuating elastomer, provides a compression deformation holding space as well as utilizes the pressure releasing part of the actuating elastomer to lead the actuating elastomer to absorb the pressure and simultaneously store a recovery elastic force; the elastomer structure of the invention utilizes the retaining edges of the inner retaining body and the outer retaining body to limit the pressure resisting surfaces of the inner edge end and the outer edge end of the actuating elastomer as well as improve the elastic load of the elastomer structure; besides, the pressure resisting surface of the outer edge end of the actuating elastomer of the elastomer structure is led to be limited by the outer retaining body and the inner edge end of the actuating elastomer is formed with the pressed surface according to the different demand of the elastic load; besides, both the inner edge end and the outer edge end of the actuating elastomer of the elastomer structure can be formed with the pressed surface as well.

Description

technical field [0001] The invention relates to an elastic body structure, in particular to an elastic body structure which can increase the compression stroke, shorten the length of the elastic body and lighten the weight. Background technique [0002] In the past, there are two main types of pressure-relieving elastomers that are commonly used and recognized by the public. Please refer to figure 1 , figure 2 , one of which is a more common metal spring (such as figure 1 ), the other is colloidal elastomer (such as figure 2 ), the two kinds of pressure-releasing elastomers are widely used in various fields, especially as vehicle shock absorbers, load-bearing mechanism shock absorbers, and mechanism pressure-resistant buffers; and the application of pressure-releasing elastomers in the aforementioned aspects is increasing The more, in addition to the effect of shock absorption and cushioning, it also has the advantage of reducing noise. Therefore, the importance of pres...

Problems solved by technology

[0003] figure 1 The commonly used product of the existing pressure-relieving elastic body shown is a metal spring, which is used in most equipment and has high durability and long life. However, the defects in the application of metal springs are:

[0008] First, the cylindrical colloidal elastic body has a small compression stroke relative to the length of the elastic body, and cannot withstand the external pressure of a higher stroke. If a higher stroke is required, the length must be increased or more stacks combined quantity, resulting in the disadvantages of excessive volume and increased weight

[0009] Second, when the cylindrical colloidal elastic body is compressed, the pressure is absorbed by the cylindrical surface around the material, and the compression stroke for absorbing the pressure is short, and there is nowhere to release the pressure due to volume deformation, so the extremely short compression stroke will Causes swelling and bulging of the peripheral side, resulting in excessive deformation and bursting of the cylindrical surface on the peripheral side, resulting in product failure. The aforementioned problems shorten the service life of this existing technology and require a large amount of maintenance

[0010] Third, the elastic load of the cylindrical colloidal elastic body is directly proportional to the cross-sectional area and density, so if a concave groove for accommodating volume deformation is made on the peripheral side, or a perforation is made in the radial direction, its increase after testing Stroke is still limited, but results in significantly lower spring loads
