It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

As shown in Figure 1 and Figure 2, one embodiment of the present invention provides a shock absorber 1, the shock absorber 1 includes a shock absorber 11 made of elastic material, the shock absorber 11 is formed with At least one air bubble 111, the air bubble 111 is filled with gas; the shock absorber 1 provided in this embodiment includes a shock absorber 11 made of elastic material, the outdoor unit of the air conditioner is fixed on the base through the shock absorber 11, and the damper The vibration seat 11 can buffer and absorb the vibration generated when the external machine is running, thereby reducing the vibration transmitted from the external machine to the base through the vibration-damping seat 11; The vibration wave and sound wave transmitted by the machine to the vibration damping seat 11 will cause the compression and vibration of the gas in the bubble 111, so the energy of the vibration wave and sound wave transmitted by the external machine can be converted into heat energy, and the vibration and noise generated by the operation of the external machine can be converted into Absorption, effectively cut off the solid sound transmission path of the outdoor unit of the air conditioner, reduce the transmission of noise to the room, so as to achieve the purpose of effective vibration reduction and sound insulation; can greatly attenuate the vibration and noise transmitted from the external unit, and improve the vibration reduction The vibration and sound insulation performance of the device 1.

According to an embodiment of the present invention, the shock absorbing seat 11 is provided with a plurality of air bubbles 111, and the plurality of air bubbles 111 are distributed in the shock absorbing seat 11. And vibration, can more fully convert the vibration and sound waves transmitted from the outdoor unit of the air conditioner into heat energy, so as to better reduce vibration and sound insulation; at the same time, a large number of air bubbles 111 can more comprehensively cut off the solid transmission path of noise.

According to an example of this embodiment, as shown in FIG. 1, multiple layers of air bubble groups are formed on the shock absorbing seat 11, and each layer of the air bubble groups includes a plurality of the air bubbles 111; The air bubbles 111 are arranged in an array; optionally, in this embodiment, the plurality of air bubbles 111 in the damping seat 11 may not be arranged in the form of air bubble groups, such as a plurality of air bubbles 111 are irregularly arranged in the vibration-damping seat 11, which can also achieve the purpose of absorbing sound through the air bubbles 111 and cutting off the solid transmission path of noise in this embodiment.

According to an embodiment of the present invention, the shock absorber 1 also includes an elastic member, and the elastic member is arranged on the shock absorber 11; Or directly installed on the substrate, the damping effect is poor, and the damper 1 provided in this embodiment includes a damping seat 11 and an elastic member, the base of the outdoor unit of the air conditioner is installed on the elastic member, through the elastic member and the damper The double vibration reduction of the vibration seat 11 can better absorb the vibration generated by the outdoor unit of the air conditioner, and the vibration reduction effect is better.

According to an example of this embodiment, the damping base 11 is provided with a plurality of elastic members with different heights, that is, one end of the plurality of elastic members is fixed on the damping base 11, and the base of the outdoor unit of the air conditioner is pressed against On the highest elastic part, the elastic part provides an elastic force for the base, and can play a role in buffering and absorbing vibrations. When the elastic force of an elastic part cannot meet the weight requirements of the outdoor unit of the air conditioner, the base will Under the action of gravity, the highest elastic piece is compressed until it contacts the second highest elastic piece. The second highest elastic piece can provide an elastic force for the base. At this time, the two elastic pieces provide the elastic force for the base as a supporting force. If the two The elastic force of the two elastic parts still cannot provide enough supporting force, then continue to compress the elastic parts, increase the number of elastic parts that provide supporting force for the base, until the supporting force provided by the elastic parts can meet the demand of the weight of the air conditioner outdoor unit. The arrangement of the above-mentioned elastic member greatly increases the weight range of the outdoor unit of the air conditioner to which the shock absorber 1 can be applied; at the same time, it can also avoid the use of a single elastic member with large rigidity and large elastic force, which causes the outdoor unit of the air conditioner with a small weight to be unable to press or lose weight. The elastic member on the vibrator 1 further leads to the problem that the damping effect of the elastic member is poor. The shock absorber in this embodiment is provided with multiple sets of different elastic members, which can not only be applicable to outdoor units of air conditioners with a large weight range, but also ensure that the outdoor units of air conditioners of each weight level can play a role of vibration reduction. effect.

According to one embodiment of the present invention, the elastic member is a spring 12 provided on the damping seat 11, one end of the spring 12 is pressed on the shock absorbing seat 11, and the other end is connected to the base of the outdoor unit of the air conditioner , the spring 12 can provide an elastic supporting force for the outdoor unit of the air conditioner; optionally, in this embodiment, the elastic member can also be other mechanisms, such as an elastic buckle, a disc spring, and the like.

According to an example of this embodiment, as shown in Figure 1 and Figure 2, a plurality of the springs 12 are provided on the elastic seat, and the plurality of springs 12 are coaxially arranged and nested with each other; optionally, The heights of the plurality of springs 12 increase sequentially from the inside to the outside. By arranging a plurality of springs 12, the purpose of multi-stage vibration reduction can be achieved, which can not only be suitable for outdoor units of air conditioners with a large weight range, but also ensure The outdoor units of air conditioners of each weight class can play the role of vibration reduction. Of course, in this example, the plurality of springs 12 may not be arranged coaxially, that is, the plurality of springs 12 are distributed around on the damping seat 11, which can also achieve the purpose of multi-stage vibration reduction in this application; In the application, a plurality of springs 12 are coaxially arranged at the center of the vibration damping seat 11, which can ensure the balance of the support of the springs 12 to the base of the outdoor unit of the air conditioner, that is, can improve the stability of the support of the springs 12 to the base.
