Referring to fig. 1 to 4, the damping foot pad 100 of the present invention includes a base 110 and a vibration isolation pad 160. The mat base 110 is provided with a vibration isolation convex part 112, the vibration isolation convex part 112 is provided with a first mounting hole 113, and the first mounting hole 113 penetrates through the mat base 110. The vibration isolation gasket 160 abuts against the vibration isolation convex portion 112, the vibration isolation gasket 160 is provided with a second mounting hole 161 corresponding to the first mounting hole 113, and one side of the vibration isolation gasket 160 is connected to the pedestal 110, so that the vibration isolation gasket 160 can be turned upwards to allow the foot 210 of the air conditioner 300 to be sleeved outside the vibration isolation convex portion 112.

In the embodiment of the present invention, the vibration-damping foot pad 100 may be an integrated structure, and certainly, may also be a split structure, which is not specifically limited. The damping foot pad 100 is made of an elastic material, has a certain elastic deformation capacity, and can achieve a good damping effect. The elastic material can be rubber, silica gel or other materials capable of generating elastic deformation. The vibration reduction foot pad 100 includes a pad 110 and a vibration isolation pad 160, the shape of the pad 110 may be designed according to the structure of a foot 210 of an air conditioner 300, a vibration isolation convex portion 112 extending upward is provided on the pad 110, and the vibration isolation convex portion 112 is located at the middle of the pad 110 or a position close to the central area. The vibration isolation pad 160 is located above the seat 110 and abuts against the upper end of the vibration isolation convex portion 112, and the distance between the vibration isolation pad 160 and the seat 110 is equal to the height of the foot 210.

In order to better fix the vibration isolation pad 160, considering that the vibration isolation pad 160 is located at a position corresponding to the middle or near the central region of the pad 110, one side of the vibration isolation pad 160 may be coupled to the pad 110. Specifically, the front side of the vibration isolation pad 160 may be connected to the pad 110, or the left side or the right side of the vibration isolation pad 160 may be connected to the pad 110, which is not particularly limited. Since one side of the vibration isolation pad 160 is connected to the pad 110, and the vibration isolation pad 160 can be elastically deformed, the vibration isolation pad 160 can be turned upside down. For example, when the vibration-damping foot pad 100 is mounted on the foot 210 of the air conditioner 300, the vibration-damping pad 160 may be turned upwards to place the foot 210 on the base 110, and the vibration-damping protrusion 112 on the base 110 passes through the mounting through hole of the foot 210, i.e., the foot 210 of the air conditioner 300 is sleeved outside the vibration-damping protrusion 112. After the feet 210 are placed on the base 110, the vibration isolation pad 160 is turned downward to abut against the vibration isolation convex portion 112, and then the fastening member 230 sequentially passes through the vibration isolation pad 160, the vibration isolation convex portion 112, and the mounting holes of the base 110 from top to bottom, thereby fixedly mounting the vibration isolation pad 160, the feet 210, and the base 110.

In the embodiment of the present invention, the vibration isolation convex portion 112 may be a vibration isolation convex pillar, or the like, that is, the cross section of the vibration isolation convex portion 112 may be a circle, a square, or another irregular shape, or the like. The vibration isolation convex part 112 is provided with a first mounting hole 113, the first mounting hole 113 penetrates through the pad 110, and the cross-sectional shape of the first mounting hole 113 may be a circle, an ellipse, a polygon or other irregular shapes. The vibration isolation gasket 160 is provided with a second mounting hole 161 corresponding to the first mounting hole 113, where "corresponding" is understood to mean that the first mounting hole 113 and the second mounting hole 161 have the same hole size and are communicated with each other. That is, the first mounting hole 113 and the second mounting hole 161 form a through hole extending in the vertical direction. The size of the through hole may be matched to the specification of the fastening member 230, that is, the diameter of the through hole may be greater than or equal to the outer diameter of the fastening member 230. The design and selection may be made for different types of fasteners 230.

The vibration reduction foot pad 100 comprises a pad seat 110 and a vibration isolation gasket 160, wherein a vibration isolation convex part 112 is arranged on the pad seat 110, a first mounting hole 113 is formed in the vibration isolation convex part 112, and the first mounting hole 113 penetrates through the pad seat 110; the vibration isolation gasket 160 abuts against the vibration isolation convex portion 112, the vibration isolation gasket 160 is provided with a second mounting hole 161 corresponding to the first mounting hole 113, and one side of the vibration isolation gasket 160 is connected to the pedestal 110, so that the vibration isolation gasket 160 can be turned upwards to allow the foot 210 of the air conditioner 300 to be sleeved outside the vibration isolation convex portion 112. Thus, when the vibration reduction foot pad 100 is installed on the foot 210 of the air conditioner 300, the vibration isolation pad 160 can be firstly turned upwards, the foot 210 is placed on the foot 110, the vibration isolation convex part 112 on the foot 110 penetrates through the installation through hole of the foot 210, namely the foot 210 of the air conditioner 300 is sleeved outside the vibration isolation convex part 112, then the vibration isolation pad 160 is turned downwards to abut against the vibration isolation convex part 112, the fastener 230 sequentially penetrates through the vibration isolation pad 160, the vibration isolation convex part 112 and the installation hole of the foot 110 from top to bottom, the fastener 230 is effectively prevented from being in direct contact with the foot 210 of the outdoor unit, so that the vibration of the compressor can be prevented from being transmitted to the installation support 220 through the foot 210 of the air conditioner 300, the vibration isolation effect of the vibration reduction foot pad 100 is improved, and the noise under the application scenes of rooms, vehicles and the like is improved.

Of course, in other embodiments, the cross-sectional area of the vibration isolation pad 160 may be substantially equal to the cross-sectional area of the vibration isolation convex portion 112, and is not particularly limited.

The shape of the vibration isolation pad 160 may be circular, elliptical, or polygonal, and is not particularly limited. Alternatively, the vibration isolation pad 160 has an axisymmetrical structure, and the second mounting hole 161 of the vibration isolation pad 160 is opened at a position where the axis of symmetry of the vibration isolation pad 160 passes. For example, in the present embodiment, the vibration isolation pad 160 is substantially quadrangular, and the second mounting hole 161 of the vibration isolation pad 160 is formed in the central area of the vibration isolation pad 160, that is, at a position where the symmetry axis of the vibration isolation pad 160 passes, so that the assembly stability of the vibration damping foot pad 100 and the foot 210 of the air conditioner 300 is improved. Of course, the vibration isolation pad 160 may have an asymmetric structure, and is not limited herein.

Considering that the vibration isolation pad 160 abuts against the upper end of the vibration isolation convex portion 112, that is, the foot 210 of the air conditioner 300 is disposed between the vibration isolation pad 160 and the pad 110, the vibration isolation pad 160 not only can prevent the fastener 230 from directly contacting the foot 210, thereby achieving a good vibration isolation effect, but also can limit the foot 210 in the up-down direction, thereby preventing the foot 210 from vibrating in the up-down direction to generate noise.

The two limiting bosses 120 may be the same or different in shape, and are not particularly limited as long as they can limit.

Referring to fig. 1 and 2, in the present embodiment, a connecting portion 162 extending toward one of the first limiting bosses 120 is disposed on one side of the vibration isolation gasket 160, and the connecting portion 162 is connected to the corresponding first limiting boss 120. For convenience of description, the first limiting protrusion 120 located at the left side of the cushion 110 may be defined as a left limiting protrusion, and the first limiting protrusion 120 located at the right side of the cushion 110 may be defined as a right limiting protrusion. The connecting portion 162 may be formed by extending the vibration isolation gasket 160 toward the left limit boss, and then the connecting portion 162 is connected to the corresponding left limit boss; of course, the connection portion 162 may be formed by extending the vibration isolation gasket 160 toward the right limit boss, and the connection portion 162 is connected to the corresponding right limit boss.

Referring to fig. 1 and 2, optionally, the width of the vibration isolation pad 160 is greater than the width of the connection portion 162. Here, the width of the vibration isolation pad 160 is a distance between both side walls of the vibration isolation pad 160 in the front-rear direction, and the width of the connection part 162 is a distance between both side walls of the connection part 162 in the front-rear direction. Therefore, on one hand, the vibration isolation gasket 160 is turned over up and down through the connecting part 162, so that the mounting and dismounting of the bottom leg 210 of the air conditioner 300 are facilitated, and on the other hand, the vibration isolation gasket 160 has a large covering area, so that the contact area between the vibration isolation gasket 160 and the bottom leg 210 can be increased, and a good limiting effect can be achieved on the bottom leg 210.

The air conditioner of the present invention includes, but is not limited to, a vehicle air conditioner and a home air conditioner. For a household air conditioner, for example, an outdoor unit of an air conditioner, is generally fixedly installed on a wall body through the installation bracket 220, and by adopting the vibration-damping foot pad 100 of the present invention, vibration of a compressor can be effectively prevented from being transmitted to the installation bracket 220, and resonance of the installation bracket 220 is prevented. For a vehicle-mounted air conditioner, the vehicle-mounted air conditioner is generally fixed on a vehicle frame through a mounting bracket 220, and by adopting the vibration-damping foot pad 100 of the invention, on one hand, vibration of a compressor can be prevented from being transmitted to the mounting bracket 220, and on the other hand, vibration of the vehicle frame can be prevented from being transmitted to the bottom foot 210 of the air conditioner 300 in the running process of a vehicle, so that the internal structure (such as the compressor and the like) of the air conditioner 300 is damaged, namely, the vibration-damping foot pad 100 has a bidirectional vibration-damping effect.

It is worth mentioning that the vibration damping foot pad 100 of the present invention still has a better vibration damping effect when the compressor of the air conditioner 300 has a high frequency or a high rotation speed. This is because the vibration amplitude of the compressor is large when the compressor is at a high frequency or a high rotation speed, and if a conventional vibration-damping foot pad is used, the vibration amplitude transmitted to the mounting bracket 220 is also large, and the resonance point of the mounting bracket 220 is usually located in a high frequency region, which easily causes the mounting bracket 220 to resonate, thereby generating a large vibration noise. However, with the vibration-damping foot pad 100 of the present invention, since the vibration-damping foot pad 100 of the present invention has a good vibration-damping effect, the vibration amplitude transmitted to the mounting bracket 220 is small, thereby more effectively improving the resonance of the mounting bracket 220 and greatly reducing the vibration noise.

In addition, referring to fig. 12 and 13, when the new damping foot pad 100 (the damping foot pad 100 of the present invention) is used, compared to the original damping foot pad 100 (the conventional damping foot pad 100), the vibration amplitude of the mounting bracket 220 is reduced to 1/3, the peak value of low-frequency buzzing caused by a wall body is reduced by 11dB (e.g., 41dB to 30dB in fig. 13), and the vibration and hearing are improved significantly when the damping foot pad 100 of the present invention is used.

The above description is only an alternative embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, which are within the spirit of the present invention, are included in the scope of the present invention.
