Conditions, so it is not technically meaningful.

At the same time, as used in this specification, such as "one", "two", "upper", etc. The language is also for the convenience of description, and is not intended to limit the scope of the creation of the creation. The change or adjustment of the relative relationship is considered to be the scope of the creation of the creation without substantial change in the technical content.

Please refer to FIG. 1 and FIG. 2 for a schematic perspective view and a cross-sectional structural view of a preferred embodiment of the present invention. The creation is a structural improvement of the damping rubber block. The damping rubber block 1 mainly comprises an elastic body 10 (for a rubber material), a first plate body 12 (for a metal plate) and a second plate body 13 (for a metal plate), wherein The elastic body 10 defines a first end 100, a second end 101 and an elastic portion 102 between the first end 100 and the second end 101. The elastic portion 102 defines a first inclined deformation section 1020 connected to the first end 100. a second inclined deformation section 1022 connected to the second end 101 and a retracted section 1024 between the first inclined deformation section 1020 and the second oblique deformation section 1022, the first end 100 defining a first oblique deformation The first buffer segment 1002 and the second end 101 connected to the segment 1020 define a second buffer segment 1010 coupled to the second oblique deformation segment 1022. The first plate body 12 is connected to the first end 100, and the second plate body 13 is connected to the second end 101.

The first first inclined deformation section 1020 and the second inclined deformation section 1022 are inclined toward the inner constricted section 1024, so that the elastic portion 102 is formed to be recessed inward. In addition, the first end 100 and the second end 101 respectively define a predetermined thickness (4 mm). Furthermore, the first plate body 12 and the second plate body 13 respectively form a plurality of mounting holes 120 and 130, and the first end 100 forms a plurality of seating portions 1004 corresponding to the mounting holes 120 of the first plate body 12, respectively. The two ends 101 form a plurality of retaining portions 1012 corresponding to the respective mounting holes 13 of the second plate body 13, respectively.

Referring to the drawings and FIG. 3 together, a schematic diagram of the use state of the cross-sectional structure of the preferred embodiment of the present invention is shown. As can be seen in Figure 3, when the first panel 12 is subjected to a horizontal force, the elastomer 10 is subjected to a lateral shear load, so that it is at both ends of the elastomer 10 and at the first end 100 and the second end, respectively. The first buffer section 1002 and the second buffer section 1010 formed on the 101 change the degree of stretching according to the strength of the lateral actuation, and combine with the first oblique deformation section 1020 defined by the elastic portion 102, and the second oblique deformation. The segment 1022 and the indented section 1024 between the first inclined deformation section 1020 and the second inclined deformation section 1022 achieve the effect of absorbing the strain energy at the first buffer section 1002 and the second buffer section 1010, thereby reducing the maximum strain concentration. Values to achieve optimum strain and increase rubber product life.

It is worth mentioning that, since the first inclined deformation section 1020 and the second inclined deformation section 1022 are inclined toward the inwardly-contracted section 1024, the strain energy is moved to the elastic portion 102, and the elastic portion 102 is caused to generate an extension type deformation, thereby achieving the distribution. The strain energy at a buffer section 1002 and the second buffer section 1010, in other words, the cross-sectional area of the elastic body 10 at the contraction section 1024 (curved surface/curve) is smaller than the cross-sectional area of the elastic body 10 at the first end 100 and the second end 101, Thereby, the maximum value at which the strain concentration is reduced can be achieved when the pulling movement in the shearing direction is performed.

The plurality of mounting holes 120, 130 on the first plate body 12 and the second plate body 13 are mainly used for mounting and fixing the damping rubber block 1, and the retaining portion 1004 and the second end on the first end 100 The retaining portion 1012 on the end 101 is used to avoid the bolts to avoid damage to the elastic body 10 caused by the installation.

The above embodiments are merely illustrative of the principles of the present invention and their effects, and are not intended to limit the present invention. Anyone familiar with the art may modify the above embodiments without departing from the spirit and scope of the creation. Therefore, the scope of protection of this creation should be as listed in the scope of the patent application described later.
