【Example】

Example 1. An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 5 is a metal material, which is a vibration damping mounting plate formed of a vibration damping member made of Al, SUS, lead-containing metal or the like and having a vibration suppressing action, and 6 is a first vibration damping mounting plate. Impact slot 2 and vibration protector 3 with slotted holes
It is provided slightly longer than the impact vibration generating component 2. Reference numeral 7 denotes a second long slot, which has one end between the first long slot 6 and the vibration protection component 3 in the vicinity of the end of the first long slot 6 in the longitudinal direction. It is provided with the other end in the vicinity.

The shock vibration generated when the shock vibration generating component 2 is operated by inputting electric power is transmitted to the vibration damping mounting plate 5, but its vibration energy is first reduced by the vibration suppressing effect of the material. Next, direct propagation in the direction of the vibration protection component 3 is blocked by the first elongated groove 6, and the vibration protection component 3 from the connection component between the end of the first elongated groove 6 and the edge of the vibration damping mounting plate 5 is blocked. The vibration energy that bypasses and propagates in the direction of the second slot 7
Is further prevented by and the influence of the malfunction of the vibration protection component 3 becomes minute.

Further, although the first slotted groove 6 and the second slotted hole 7 are provided between the impact vibration generating component 2 and the vibration protection component 3, the slotted holes may be further provided, and thus Propagation of vibration energy is reduced due to the material vibration suppression effect due to the long zigzag detour.

Example 2. FIGS. 2 and 3 show another embodiment. Reference numeral 8 is a long punch-out reinforcing rib protruding from the surface of the vibration damping mounting plate 5 by a press die (not shown).
Is formed between the vibration protection component 3 and the impact vibration generation component 2 to a position near the edge of the vibration damping mounting plate 5. Reference numeral 9 denotes a groove hole, which is formed in the top portion of the embossed reinforcing rib 8 along the longitudinal direction so as to be longer than the impact vibration generating component 2. The impact vibration generated from the impact vibration generating component 2 is prevented from directly propagating to the vibration protection component 3 through the slot 9. The longer the length of the slot 9, the more effective it is.
Since the connecting portion of the base material between the end portion and the edge portion of the vibration damping mounting plate 5 is reduced, the strength is reduced and breakage is caused.
Thus, the strength of the base material is improved to improve the vibration resistance effect and the slot 9 is provided longer.

Example 3. FIG. 4 and FIG. 5 show another embodiment, and 10 is a first embossing and holding rib projectingly provided on the vibration damping mounting plate 5 so as to surround the impact vibration generating component 2 with a predetermined width. 11 is a slotted groove, which is formed on the entire surface of the first embossing holding rib 10 on the side of the vibration protection component 3 and a part of the rib portion which is bent and continuous with this, for example, at the top portion of the rib. Has been done. Reference numeral 12 denotes a second embossing and holding rib projectingly provided on the vibration damping mounting plate 5 by surrounding the vibration protection component 3 with a rear surface groove portion having a predetermined width. The vibration energy loss coefficient is present inside the rear surface groove portion, that is, the protruding portion of the rib. Is filled with a vibration absorbing member (13) made of rubber, plastic, or the like.

The shock-vibration generated from the shock-vibration-generating component 2 has its propagation direction limited by the groove groove 11 and is filled inside the protruding portion of the second embossing holding rib 12.
At 13, vibration energy is reduced. In addition, the ejection holding rib
Numerals 10 and 12 are reinforcements for preventing vibration of the vibration damping mounting plate 5 when shock vibration occurs and for providing vibration resistance.

Example 4. FIG. 6 shows still another embodiment, in which the width 14 of the vibration damping mounting plate 5 is about 10 to
It is a wide groove hole of about 20 mm and is provided longer between the shock vibration generating component 2 and the vibration protection component 3 than the shock vibration generating component 2, and the vibration absorbing member 15 such as rubber or plastic is raised in the wide groove hole and the groove edge. Are filled. The vibration absorbing member 15 absorbs vibration energy and prevents the vibration damping mounting plate 5 from being deteriorated in strength due to the drilling of the wide slot 14.

Example 5. FIG. 7 shows another embodiment, in which 16 and 17 are sheet-like vibration absorbing members made of rubber or plastic having a large loss coefficient of impact vibration energy, which are the impact vibration generating component 2 and the vibration protection component, respectively. The same size as the above parts are laid on the underside of the vibration damping mounting plate 5
Be attached to. The shock vibration generated from the shock vibration generating component 2 is first absorbed and reduced by the vibration absorbing member 16, and the remaining vibration energy that is not absorbed is sequentially absorbed by the vibration damping mounting plate 5 and the vibration absorbing member 17, and the vibration protection component is then absorbed. The effect on 3 is reduced.

[0024]

First between the shock-vibration generating component and the vibration protection component
The long slot and the second long slot are provided to prevent the vibration energy from going straight, and to provide a zigzag detour to sequentially reduce the vibration energy by the damping action of the damping mounting plate.

Further, by providing the punched-out reinforcing ribs with grooves, the punched-out reinforcing ribs improve the strength of the vibration-damping mounting plate to have a vibration-proof effect, and the groove holes give a vibration-damping effect.

In addition, the first and second embossing holding ribs increase the strength to provide a vibration-proof effect, and the [-] slotted hole is provided with a detour in the direction of propagation of the vibration energy to suppress the vibration of the vibration damping mounting plate. The action is increased, and the vibration is further reduced by the vibration absorbing member filled in the second embossing holding rib.

The wide groove hole is filled with the vibration absorbing member to prevent the strength of the vibration damping mounting plate from being lowered and to reduce the propagation of the vibration energy.

Further, the generated vibration energy is first reduced by the vibration absorbing member provided in the shock vibration generating component,
Next, it is further reduced while propagating through the vibration damping mounting plate, and further reduced by another vibration absorbing member provided under the vibration protection member, so that the influence on the vibration protection member is reduced.
