The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.
Referring to fig. 1 and 2, there is shown a structure of a vibration isolator according to the present invention, which includes a fixed platform 1, a base frame 2, and a shock-absorbing member 3 disposed between the fixed platform 1 and the base frame 2, as shown in the drawings. The base frame 2 is, for example, a mounting base of an outdoor unit of a variable frequency air conditioner, and is fixedly mounted on the fixing platform (fixing bracket) 1 through a connecting bolt 4 to fix the outdoor unit of the variable frequency air conditioner. The damping member 3 has an elastic supporting claw 31 for supporting the base frame 2, a gap is formed between the fixing platform 1 and the base frame 2 under the supporting action of the elastic supporting claw 31, and the effect of attenuating the vibration transmission between the outdoor unit of the variable frequency air conditioner and the fixing bracket and further effectively attenuating the noise transmitted to the indoor by the fixing bracket is achieved by using the self elastic deformation characteristic of the elastic supporting claw 31.
A preferred embodiment of the damping member 3 can be seen in fig. 1, the damping member 3 comprising: the abutting sleeve 32 is sleeved on the connecting bolt 4, the first end of the abutting sleeve 32 is limited by a locking nut 41 in threaded connection with the connecting bolt 4, and the second end of the abutting sleeve extends into a position between the base frame 2 and the fixed platform 1; the connecting plate 33 is disposed at the second end of the pressing sleeve 32, and the outer side of the connecting plate 33 is provided with elastic supporting claws 31, for example, the elastic supporting claws 31 are disposed on two opposite sides of the connecting plate 33 and are in a concave structure recessed toward the fixed platform 1. Thus, when the outdoor unit of the inverter air conditioner is installed, the locking nut 41 is tightened, the locking nut 41 pushes the abutting sleeve 32 to move downwards, the tail end of the elastic supporting claw 31 positioned outside the connecting plate 33 is enabled to tilt and support the base frame 2, when the outdoor unit of the inverter air conditioner vibrates, the concave opening of the elastic supporting claw 31 correspondingly opens or closes, the effect of a damping spring is achieved, and the effects of damping and reducing noise are achieved. A washer 5 may also be provided between the lock nut 41 and the abutment sleeve 32. Preferably, the connecting bolt 4 is an expansion bolt, the bolt head of the expansion bolt is used for being installed in the fixed platform 1, when the base frame 2 is not fixed on the fixed platform 1, the connecting bolt 4 and the locking nut 41 are both arranged on the base frame 2, the pressing sleeve 32 of the damping component is nested on the base frame (outdoor unit footing), and the damping component is not easy to fall off when the outdoor unit of the variable frequency air conditioner is carried under the action of the connecting bolt 4 and the locking nut 41.
Preferably, the end of the elastic support claw 31 has a circular-arc-shaped flange 34 to avoid the elastic support claw 31 from scratching the base frame 2 during use. Preferably, the pressing sleeve 32, the connecting plate 33 and the elastic supporting claw 31 are integrally formed sheet metal parts so as to facilitate processing and manufacturing. In addition, in order to reduce the collision noise between the elastic support claws 31 and the base frame 2, as can be seen from fig. 1, an elastic deformation layer 6 is installed between the elastic support claws 31 and the base frame 2. Preferably, the elastic deformation layer 6 is made of rubber, and it substantially matches the shape of the connecting plate 33 and the elastic supporting claw 31, and the middle part has a mounting hole suitable for being sleeved on the pressing sleeve 32, and the outer side is located between the elastic supporting claw 31 and the base frame 2.
The invention also provides a fixing device of the outdoor unit of the air conditioner, which comprises the anti-vibration device, wherein the footing of the outdoor unit of the air conditioner is the base frame 2, the fixing support fixedly connected with the footing is the fixing platform 1, and the damping piece 3 is arranged between the footing and the fixing support.
Fig. 3 shows a mechanical model of a vibration system of an outdoor unit for an air conditioner having a vibration absorbing member 3 with an elastic deformation layer 6.

For the outdoor unit of the variable frequency air conditioner, the vibration transmitted from the outdoor unit to the fixed platform 1 can be greatly reduced under the action of the shock absorbing member 3 with the elastic deformation layer 6, and further, the noise transmitted from the fixed platform 1 to the indoor can be reduced.
Referring to fig. 4, there is shown the damping characteristics of the damping member 3 obtained for different thicknesses of the damping member 3 (with the elastically deformable layer 6). In fig. 4, the thickness 1 is 0.1 mm; the thickness 2 is 0.2 mm; the thickness is 3-0.3 mm; the thickness 4 is 0.4 mm; the thickness 5 is 0.5 mm. The attenuation characteristic curve is obtained by the following formula,
X＝[Zp]-1·F
Zp＝-ω2[M]+jω[C]+[K]
F2＝k2x2+c2x2
wherein, f is the force of the whole machine, omega is the damping natural frequency, X is the frequency of the damping piece, and h is the thickness of the damping piece. F2The other variables are the same as in fig. 3 for the force acting on the fixed platform, i.e. the load described by the damping characteristic. Therefore, the shock absorbing member 3 can be selected to have a proper thickness according to the structural characteristics and the concerned frequency range of the outdoor unit of the variable frequency air conditioner, so that the applicable frequency range of the shock absorbing member 3 is wider.
