The setting mode has the advantages that: the counterweight member 12 of the outdoor unit effectively disperses the acting force of the vibration member 11 caused by the sudden change of the operation state, reduces the vibration influence of the vibration member 11 on the chassis 13 and reduces the resonance noise of the chassis 13; on the other hand, the counterweight member 12 provides a reaction force to the vibration member 11 through the chassis 13 when the vibration member 11 is started or stopped, so that the vibration effect of the vibration member 11 is effectively buffered, and the damping effect of the vibration member 11 of the outdoor unit is improved.

The outdoor unit of the present invention will be described in detail with further reference to fig. 1 to 7, wherein fig. 1 is a front view of an overall installation structure of the outdoor unit of the present invention; fig. 2 is the utility model discloses a three-dimensional view of whole mounting structure of off-premises station one, fig. 3 is the utility model discloses a three-dimensional view of whole mounting structure of off-premises station two, fig. 4 is the utility model discloses a chassis structure schematic diagram, fig. 5 is the utility model discloses a damping member structure schematic diagram, fig. 6 is the utility model discloses a screw structure schematic diagram, fig. 7 is the utility model discloses a counter weight component structure schematic diagram.

As shown in fig. 1 to 4, in one possible embodiment, the vibration member 11 of the outdoor unit is a compressor 111, a base plate 13 of the compressor 111 is provided with a mounting through hole 131 (see fig. 4), the compressor 111 and the weight member 12 are fixedly connected after passing through the mounting through hole 131 by a screw 132, and the base plate 13 is abutted against the compressor 111 and the weight member 12 respectively;

the setting mode has the advantages that: the counterweight component 12 is added at the bottom of the chassis 13, when the compressor 111 is started or stopped, the screw 132 which passes through the mounting through hole 131 on the chassis 13 is used as a stress lever, the mounting through hole 131 is used as a fulcrum, and an acting force opposite to the movement trend is given to the compressor 111 through the counterweight component 12, so that the influence of the compressor 111 on the chassis 13 when the compressor 111 is started and stopped is reduced, the vibration of the compressor 111 is buffered, the resonance noise of the chassis 13 is reduced, and the damping effect is improved.

As shown in fig. 1, in a preferred embodiment, a damping member 14 is further disposed between the compressor 111 and the chassis 13 and/or between the weight member 12 and the chassis 13, so as to effectively damp the acting force among the compressor 111, the chassis 13 and the weight member 12 and reduce the overall vibration amplitude. Specifically, as shown in fig. 5, the damping member 14 is a hollow cylindrical damping rubber block 141, and a damping groove 1411 is formed on the outer side of the damping rubber block 141, so that the displacement of the damping rubber block 141 when the damping force is applied is increased, and the damping and buffering effects are improved. More preferably, as shown in fig. 1 and 6, a spacer 133 is further disposed between a screw cap 1321 of the screw 132 and the weight member 12 and/or between a lock nut 1322 of the screw 132 and the compressor 111, and the spacer 133 can uniformly distribute an acting force transmitted to the chassis 13 and the weight member 12 through the screw 132 and a reaction force transmitted to the compressor 111 by the weight member 12 through the screw 132 when the compressor 111 is started or stopped, so as to increase a stress area between the two, avoid stress concentration, and effectively buffer vibration.

In another preferred embodiment, the through hole flanging is further arranged at the mounting through hole 131 of the base plate 13 of the compressor 111, so that the transverse displacement between the compressor 111 and the base plate 13 and other components is effectively limited, the vibration influence of the compressor 111 is reduced, and the structural strength at the through hole is also increased.

In an alternative embodiment, the vibration member 11 may be not only used for the compressor 111, but the vibration member 11 may also be an oil separator.

In another alternative embodiment, as shown in fig. 1, 3 and 7, the weight member 12 is disc-shaped, which ensures that the center of gravity of the weight member 12 and the center of gravity of the vibration member 11 are on the same central axis, better distributing the stress. Preferably, the material of the weight member 12 is solid metal, and/or the mass of the weight member 12 is between one third and one half of the mass of the vibration member 11. The weight member 12 has an excessively small mass, and does not have the effects of lowering the center of gravity of the vibration member 11, dispersing the force of the vibration member 11, and reducing the vibration amplitude of the vibration member 11; the mass is too large, which increases the overall load of the outdoor unit and increases the cost of the outdoor unit, but is not suitable.

In particular, the installation grooves 121 of the cushion rubber blocks 141 are uniformly distributed on the surface of the weight member 12, and the installation grooves 121 can simultaneously limit the relative displacement between the cushion rubber blocks 141 and the weight member 12 while facilitating the installation of the cushion rubber blocks 141 of the weight member 12; the damping rubber block 141 is provided with a chassis reinforcing flange abdicating groove 1412 and a press claw mounting groove 1413, so that the damping rubber block 141 and each component can be conveniently mounted and fixed.

In particular, the damping rubber block 141 is made of high-density silicone rubber, and the damping rubber block is commonly produced as the damping member 14, so that the production cost is saved.

In particular, the screw 132 is the main connecting member of the vibrating member 11, the chassis 13 and the weight member 12, and the head of the screw cap 1321 thereof is hexagonal (see fig. 6) for easy positioning and fixing.

In particular, the washer 133 between the nut 1321 of the screw 132 and the weight member 12 has a diameter of 35mm, which effectively and uniformly distributes the force and avoids stress concentration points.

Specifically, the chassis 13 is a circular regular or irregular shape capable of accommodating at least the weight member where the vibration member 11 is fixed.

In summary, the vibration member 11 and the weight member 12 are connected and mounted on two sides of the chassis 13, and the acting force generated when the vibration member 11 is started or stopped can be uniformly and smoothly dispersed and transmitted to the weight member 12 through the damping member 14 and the chassis 13, so that most of the vibration acting force caused by the vibration member 11 is dissipated; meanwhile, under the buffering of the damping member 14, the screw 132 penetrating through the mounting through hole 131 on the chassis 13 is used as a stress lever, the mounting through hole 131 is used as a fulcrum, and an acting force opposite to the motion trend of the vibration member 11 is given to the vibration member 11 through the counterweight member 12, so that the vibration influence on the chassis 13 when the vibration member 11 is started and stopped is buffered, the vibration amplitude is reduced, the resonance noise of the chassis 13 is reduced, and the damping effect is improved.

For example, in another alternative embodiment, the installation through hole 131 of the base plate 13 of the compressor 111 is obviously not limited to be provided with a through hole flanging, but may be reinforced by welding other reinforcing ribs, blocking plates, etc., as long as the transverse displacement between the compressor 111 and the base plate 13 and other components can be limited, and the vibration effect of the compressor 111 can be reduced, which do not deviate from the principle of the present invention, and therefore all will fall within the protection scope of the present invention.

For example, in another alternative embodiment, the shape of the weight member 12 is obviously not limited to a disc shape, but may also be a square, a polygon, an ellipse, etc., the structure of the weight member 12 is variable, and those skilled in the art can flexibly adjust according to actual needs, without departing from the principle of the present invention, and therefore, all will fall within the protection scope of the present invention.

For example, in another alternative embodiment, the damping member 14 is not limited to the damping rubber block 141, but may be a spring, an elastic plastic, etc., as long as it can buffer the acting force between the connecting members and reduce the vibration, which do not depart from the principle of the present invention, and thus all will fall within the protection scope of the present invention.
