[0052] The realization, functional features and advantages of the object of the present invention will be further described with reference to the embodiments and the attached drawings. Detailed implementation manners

[0053] It should be noted that if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, such descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first", "second" may explicitly or implicitly include at least one of such features. In addition, the meaning of "and / or" appearing throughout the text is that it includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or a solution where A and B are satisfied simultaneously.

[0054] The present invention provides a vibration damping foot pad. Among them, the vibration damping foot pad can effectively prevent the fastener from directly contacting the bottom feet of the air conditioner, thereby avoiding the resonance phenomenon caused by the vibration of the compressor being transmitted to the mounting bracket through the bottom feet.

[0055] Please refer to Figures 1 to 4 , the vibration damping foot pad 100 proposed by the present invention includes a pad base 110 and a vibration isolation gasket 160. The pad base 110 is provided with a vibration isolation convex portion 112. The vibration isolation convex portion 112 is provided with a first mounting hole 113, and the first mounting hole 113 penetrates through the pad 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. One side of the vibration isolation gasket 160 is connected to the pad base 110 so that the vibration isolation gasket 160 can be turned upwards for the bottom feet 210 of the air conditioner 300 to be sleeved outside the vibration isolation convex portion 112.

[0056] In an embodiment of the present invention, the damping foot pad 100 may be of an integral structure, or may also be of a split structure, without specific limitation. The damping foot pad 100 is made of an elastic material and has a certain elastic deformation ability, which can achieve a good damping effect. The elastic material may be rubber, silica gel or other materials that can undergo elastic deformation. The damping foot pad 100 includes a pad base 110 and a vibration isolation gasket 160. The shape of the pad base 110 can be designed according to the structure of the bottom feet 210 of the air conditioner 300. An upwardly extending vibration isolation convex portion 112 is provided on the pad base 110, and the vibration isolation convex portion 112 is located in the middle of the pad base 110 or at a position close to the central area. The vibration isolation gasket 160 is located above the pad base 110 and abuts against the upper end of the vibration isolation convex portion 112. The distance between the vibration isolation gasket 160 and the pad base 110 is the same as the height of the bottom feet 210.

[0057] Considering that the vibration isolation gasket 160 is correspondingly located in the middle of the pad base 110 or at a position close to the central area, in order to better fix the vibration isolation gasket 160, one side of the vibration isolation gasket 160 can be connected to the pad base 110. Specifically, it can be that the front side of the vibration isolation gasket 160 is connected to the pad base 110, or the left side or the right side of the vibration isolation gasket 160 is connected to the pad base 110, without specific limitation. Since one side of the vibration isolation gasket 160 is connected to the pad base 110, and at the same time, the vibration isolation gasket 160 can undergo elastic deformation, the vibration isolation gasket 160 can be turned up and down. For example, when installing the damping foot pad 100 on the bottom feet 210 of the air conditioner 300, the vibration isolation gasket 160 can be turned upwards first to facilitate placing the bottom feet 210 on the pad base 110 and enabling the vibration isolation convex portion 112 on the pad base 110 to pass through the installation through hole of the bottom feet 210, that is, the bottom feet 210 of the air conditioner 300 are sleeved outside the vibration isolation convex portion 112. After the bottom feet 210 are placed on the pad base 110, the vibration isolation gasket 160 is turned downwards to abut against the vibration isolation convex portion 112. Then, by making the fastener 230 pass through the installation holes of the vibration isolation gasket 160, the vibration isolation convex portion 112 and the pad base 110 from top to bottom in sequence, the fixed installation of the vibration isolation gasket 160, the bottom feet 210 and the pad base 110 is thus achieved.

[0058] In an embodiment of the present invention, the vibration isolation convex portion 112 may be a vibration isolation convex column, a vibration isolation convex platform, etc., that is, the cross-section of the vibration isolation convex portion 112 may be circular, square, or other special-shaped shapes, etc. The vibration isolation convex portion 112 is provided with a first mounting hole 113, the first mounting hole 113 penetrates through the pad base 110, and the cross-sectional shape of the first mounting hole 113 may be circular, oval, polygonal, or other special-shaped shapes, etc. The vibration isolation gasket 160 is provided with a second mounting hole 161 corresponding to the first mounting hole 113. Here, "corresponding" can be understood as that the hole diameters of the first mounting hole 113 and the second mounting hole 161 are the same and communicate with each other. That is, the first mounting hole 113 and the second mounting hole 161 form a through hole extending in the up and down direction. The hole diameter of this through hole matches the specification of the fastener 230, that is, the hole diameter of this through hole may be greater than or equal to the outer diameter of the fastener 230. It can be designed and selected according to different models of the fastener 230.

[0059] The vibration damping foot pad 100 of the present invention includes a pad base 110 and a vibration isolation gasket 160. The pad base 110 is provided with a vibration isolation convex portion 112, the vibration isolation convex portion 112 is provided with a first mounting hole 113, and the first mounting hole 113 penetrates through the pad 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 pad base 110 so that the vibration isolation gasket 160 can be turned upwards for the bottom feet 210 of the air conditioner 300 to be sleeved outside the vibration isolation convex portion 112. In this way, when installing the vibration damping foot pad 100 on the bottom feet 210 of the air conditioner 300, the vibration isolation gasket 160 can be turned upwards first, the bottom feet 210 are placed on the pad base 110, and the vibration isolation convex portion 112 on the pad base 110 is passed through the mounting through hole of the bottom feet 210, that is, the bottom feet 210 of the air conditioner 300 are sleeved outside the vibration isolation convex portion 112, and then the vibration isolation gasket 160 is turned downwards to abut against the vibration isolation convex portion 112. By making the fastener 230 pass through the mounting holes of the vibration isolation gasket 160, the vibration isolation convex portion 112 and the pad base 110 from top to bottom in sequence, it effectively avoids the direct contact between the fastener 230 and the bottom feet 210 of the outdoor unit, thereby preventing the vibration of the compressor from being transmitted to the mounting bracket 220 through the bottom feet 210 of the air conditioner 300, improving the vibration isolation effect of the vibration damping foot pad 100, and further improving the noise in application scenarios such as rooms and vehicles.

[0060] Please refer to Figure 3 and Figure 4, in this embodiment, the cross-sectional area of the vibration isolation gasket 160 is larger than that of the vibration isolation convex portion 112. When the foot 210 is placed between the pad base 110 and the vibration isolation gasket 160, the vibration isolation gasket 160 can abut against the upper surface of the foot 210, increasing the contact area between the vibration isolation gasket 160 and the foot 210, so that a good limiting effect can be exerted on the foot 210. Of course, in other embodiments, the cross-sectional area of the vibration isolation gasket 160 may also be approximately equal to that of the vibration isolation convex portion 112, without specific limitation.

[0061] The shape of the vibration isolation gasket 160 may be circular, elliptical or polygonal, without specific limitation. Optionally, the vibration isolation gasket 160 is an axisymmetric structure, and the second mounting hole 161 of the vibration isolation gasket 160 is opened at a position where the axis of symmetry of the vibration isolation gasket 160 passes through. For example, in this embodiment, the vibration isolation gasket 160 is generally quadrilateral, and the second mounting hole 161 of the vibration isolation gasket 160 is opened in the central area of the vibration isolation gasket 160, that is, at a position where the axis of symmetry of the vibration isolation gasket 160 passes through, thus improving the assembly stability of the vibration damping foot pad 100 and the foot 210 of the air conditioner 300. Of course, the vibration isolation gasket 160 may also be an asymmetric structure, without special limitation here.

[0062] Considering that the vibration isolation gasket 160 abuts against the upper end of the vibration isolation convex portion 112, that is, the foot 210 of the air conditioner 300 is arranged between the vibration isolation gasket 160 and the pad base 110, the vibration isolation gasket 160 can not only avoid the direct contact between the fastener 230 and the foot 210, achieving a good vibration isolation effect, but also limit the foot 210 in the up and down direction, preventing the foot 210 from vibrating in the up and down direction and generating noise.

[0063] Please refer to Figure 1 and Figure 2 , in order to limit the foot 210 in the left and right directions, in one embodiment, two first limiting bosses 120 are respectively arranged on the opposite sides of the pad base 110, and the two first limiting bosses 120 respectively have limiting planes 121 facing each other, and the two limiting planes 121 are used to limit the left and right sides of the foot 210 of the air conditioner 300, preventing the foot 210 from moving left and right and generating noise. Among them, the shapes of the two limiting bosses 120 may be the same or different, without special limitation, as long as they can play a limiting role.

[0064] Please refer to Figure 1 and Figure 2, in this embodiment, a connecting portion 162 extending toward one of the first limiting bosses 120 is provided on one side of the vibration isolation gasket 160, and the connecting portion 162 is connected to the corresponding first limiting boss 120. For ease of description, the first limiting boss 120 on the left side of the pad base 110 can be defined as the left limiting boss, and the first limiting boss 120 on the right side of the pad base 110 can be defined as the right limiting boss. The connecting portion 162 may be formed by the vibration isolation gasket 160 extending toward the left limiting boss, and then the connecting portion 162 is connected to the corresponding left limiting boss; of course, the connecting portion 162 may also be formed by the vibration isolation gasket 160 extending toward the right limiting boss, and then the connecting portion 162 is connected to the corresponding right limiting boss.

[0065] Please refer to Figure 1 and Figure 2 , optionally, the width of the vibration isolation gasket 160 is greater than the width of the connecting portion 162. Here, the width of the vibration isolation gasket 160 refers to the distance between the two side walls of the vibration isolation gasket 160 in the front-rear direction, and the width of the connecting portion 162 refers to the distance between the two side walls of the connecting portion 162 in the front-rear direction. In this way, on the one hand, the vibration isolation gasket 160 can be turned up and down through the connecting portion 162, which is convenient for the installation and disassembly of the feet 210 of the air conditioner 300. On the other hand, the vibration isolation gasket 160 has a larger coverage area, so that the contact area between the vibration isolation gasket 160 and the feet 210 can be increased, and a good limiting effect on the feet 210 can be achieved.

[0066] Please refer to Figure 1 and Figure 2 , in order to limit the feet 210 in the front-rear direction, in one embodiment, a second limiting boss 130 is provided at the rear end of the pad base 110, and the second limiting boss 130 is used to limit the feet 210 of the air conditioner 300 in the front-rear direction. Optionally, as Figure 7 and Figure 8 shown, the second limiting boss 130 is in a stepped shape and includes a first plane 131 and a second plane 132, and the first plane 131 is higher than the second plane 132. By setting the second limiting boss 130 in a stepped shape, on the one hand, a good limiting effect on the feet 210 in the front-rear direction can be achieved, avoiding the front-rear displacement of the feet 210 relative to the vibration damping foot pad 100. In this way, it can be ensured that the vibration damping foot pad 100 always has a better vibration isolation effect; on the other hand, the contact area between the feet 210 and the second limiting boss 130 can be increased, so that the second limiting boss 130 can play a good supporting role on the feet 210, and the stability of the assembly structure is improved.

[0067] Please refer to Figure 1 and Figure 3, in one embodiment, a plurality of first avoidance notches 140 extending in the up and down direction are provided on the peripheral wall of the cushion base 110, and the plurality of first avoidance notches 140 are distributed at intervals along the circumferential direction of the cushion base 110. Among them, the shapes of the plurality of first avoidance notches 140 may be the same or different, and no special limitation is made. The setting of the plurality of first avoidance notches 140 can, on the one hand, save materials and achieve the purpose of reducing costs; on the other hand, it is beneficial for the cushion base 110 to deform when being squeezed, thereby improving the vibration damping effect of the vibration damping foot pad 100.

[0068] Please refer to Figure 1 and Figure 3 , in another embodiment, a second avoidance notch 150 extending along the circumferential direction of the cushion base 110 is provided on the peripheral wall of the cushion base 110. Specifically, the second avoidance notch 150 is a U-shaped groove. The number of the second avoidance notches 150 may be one, two or more. If the number of the second avoidance notches 150 is at least two, then at least two of the second avoidance notches 150 are distributed at intervals along the height direction (up and down direction) of the cushion base 110. The second avoidance notch 150 is provided above the plurality of first avoidance notches 140. Similarly, the setting of the second avoidance notch 150 can, on the one hand, save materials and achieve the purpose of reducing costs; on the other hand, it is beneficial for the cushion base 110 to deform when being squeezed, further improving the vibration damping effect of the vibration damping foot pad 100.

[0069] Please refer to Figures 5 to 10 , the present invention also proposes a vibration damping device 200, and the vibration damping device 200 includes a vibration damping foot pad 100. The specific structure of the vibration damping foot pad 100 refers to the above embodiments. Since the vibration damping device 200 adopts all the technical solutions of the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, and will not be elaborated here one by one.

[0070] In an embodiment of the present invention, the vibration damping device 200 further includes a base foot 210, a mounting bracket 220, and a fastener 230. The base foot 210 is sleeved outside the vibration isolation convex portion 112 of the vibration damping foot pad 100; the mounting bracket 220 is disposed below the vibration damping foot pad 100; the fastener 230 passes through the first mounting hole 113 and the second mounting hole 161 to fixedly connect the base foot 210 and the mounting bracket 220. Specifically, the base foot 210 is provided with a mounting through hole for the vibration isolation convex portion 112 to pass through. When the base foot 210 is placed between the pad seat 110 and the vibration isolation gasket 160, the vibration isolation convex portion 112 passes through the mounting through hole so that the base foot 210 is sleeved outside the vibration isolation convex portion 112. Wherein, the shape of the vibration isolation convex portion 112 is adapted to the shape of the mounting through hole. Optionally, the vibration isolation convex portion 112 is cylindrical, and the outer diameter of the vibration isolation convex portion 112 is less than or equal to the inner diameter of the mounting through hole, so that it is convenient to smoothly sleeve the base foot 210 outside the vibration isolation convex portion 112.

[0071] For the vibration damping device 200 of the present invention, when the vibration damping foot pad 100 is installed on the base foot 210 of the air conditioner 300, the vibration isolation gasket 160 can be first turned upwards, the base foot 210 can be placed on the pad seat 110, and the vibration isolation convex portion 112 on the pad seat 110 can be passed through the mounting through hole of the base foot 210 so that the base foot 210 of the air conditioner 300 is sleeved outside the vibration isolation convex portion 112 (as Figure 8 and Figure 9 shown), and then the vibration isolation gasket 160 is turned downwards to abut against the vibration isolation convex portion 112. By making the fastener 230 pass through the mounting holes of the vibration isolation gasket 160, the vibration isolation convex portion 112, and the mounting bracket 220 from top to bottom in sequence, the base foot 210, the vibration damping foot pad 100, and the mounting bracket 220 are fixed together (as Figure 8 、 Figure 9 、 Figure 10 and Figure 11 shown). Herein, it is effectively avoided that the fastener 230 directly contacts the base foot 210, so that the vibration of the compressor can be prevented from being transmitted to the mounting bracket 220 through the base foot 210 of the air conditioner 300, the vibration isolation effect of the vibration damping foot pad 100 is improved, and the noise in application scenarios such as rooms is further improved.

[0072] The structure of the base foot 210 will be introduced in detail below. Please refer to Figure 7 and Figure 8, in the embodiments of the present invention, the foot 210 includes a mounting portion 211, the mounting through-hole is provided in the mounting portion 211, an edge of the mounting through-hole extends towards the cushion base 110 to form a first abutting arm 212, and the first abutting arm 212 abuts against the cushion base 110. Specifically, the first abutting arm 212 is in a cylindrical shape. Since the vibration isolation convex portion 112 is made of an elastic material, by providing the first abutting arm 212, a good supporting effect can be exerted on the vibration isolation gasket 160, thereby preventing the vibration isolation convex portion 112 from being squeezed and deformed. In order to further improve the supporting effect of the foot 210 on the vibration isolation gasket 160, the front edge of the foot 210 can extend towards the cushion base 110 to form a second abutting arm 213.

[0073] Furthermore, the foot 210 includes a first planar abutting portion 214 and a second planar abutting portion 215. The first planar abutting portion 214 is connected to the second planar abutting portion 215, and the second planar abutting portion 215 is connected to the mounting portion 211. Wherein, the first planar abutting portion 214 and the second planar abutting portion 215 are smoothly connected through a first inclined portion, and the second planar abutting portion 215 and the mounting portion 211 are smoothly connected through a second inclined portion. The first planar abutting portion 214 abuts against the first plane 131, and the second planar abutting portion 215 abuts against the second plane 132.

[0074] Here, by making the foot 210 include the first planar abutting portion 214 and the second planar abutting portion 215, and the first planar abutting portion 214 abuts against the first plane 131, and the second planar abutting portion 215 abuts against the second plane 132, the contact area between the foot 210 and the cushion base 110 is increased. In this way, the cushion base 110 can exert a good supporting effect on the foot 210, improving the assembly stability of the vibration damping device 200; at the same time, it can also make more vibrations of the compressor be transmitted to the vibration isolation gasket 160 and absorbed by the cushion base 110, thereby weakening the transmission of the compressor's vibrations to the fixed bracket 220, effectively improving the resonance phenomenon; in addition, it can also play a good front-back limiting role on the foot 210, preventing the foot 210 from shifting back and forth relative to the vibration damping foot pad 100, so as to ensure that the vibration damping foot pad 100 always has a better vibration isolation effect.

[0075] Please refer to Figure 7 and Figure 8 , the distance between the second planar abutting portion 215 and the cushion base 110 is greater than the distance between the mounting portion 211 and the cushion base 110. Since the foot 210 is generally a sheet metal part, by providing a plurality of bending portions, the stiffness of the foot 210 can be improved, thereby playing a better supporting role.

[0076] In the above embodiments, the structure of the mounting bracket 220 can be various, such as a flat bracket or a triangular bracket, etc., which is not specifically limited herein and can be selected and designed according to actual usage needs.

[0077] Please refer to Figure 11 and Figure 12 , the present invention also provides an air conditioner 300, which includes a vibration damping device 200. The specific structure of the vibration damping device 200 refers to the above embodiments. Since the air conditioner 300 of the present invention adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated herein one by one.

[0078] In the embodiments of the present invention, the air conditioner includes an air conditioner body 210 and a vibration damping device 220. The air conditioner body 310 includes a chassis, and the chassis is provided with the feet 210. The number of the feet 210 can be one, two, three or more. The feet 210 are sleeved outside the vibration isolation convex portion 112 of the vibration damping foot pad 100; the mounting bracket 220 is provided with a third mounting hole, and the fastener 230 passes through the first mounting hole 113, the second mounting hole 161 and the third mounting hole to fixedly connect the feet 210 with the mounting bracket 220.

[0079] The air conditioner of the present invention includes, but is not limited to, vehicle-mounted air conditioners and household air conditioners. For household air conditioners, such as the outdoor unit of an air conditioner, it is generally fixedly installed on a wall through a mounting bracket 220. By using the vibration damping foot pad 100 of the present invention, the vibration of the compressor can be effectively prevented from being transmitted to the mounting bracket 220, and the resonance of the mounting bracket 220 can be avoided. For vehicle-mounted air conditioners, it is generally fixed on the vehicle frame through a mounting bracket 220. By using the vibration damping foot pad 100 of the present invention, on the one hand, the vibration of the compressor can be prevented from being transmitted to the mounting bracket 220, and on the other hand, the vibration of the vehicle frame during driving can also be prevented from being transmitted to the feet 210 of the air conditioner 300, thereby damaging the internal structure (such as the compressor, etc.) of the air conditioner 300. That is, the vibration damping foot pad 100 has a two-way vibration isolation effect.

[0080] It is worth mentioning that when the compressor of the air conditioner 300 has a high frequency or high rotational speed, the vibration damping foot pad 100 of the present invention still has a better vibration isolation effect. This is because when the compressor has a high frequency or high rotational speed, the vibration amplitude of the compressor is relatively large. If a traditional vibration damping foot pad is used, the vibration amplitude transmitted to the mounting bracket 220 will also be relatively large, and the resonance point of the mounting bracket 220 is usually located in the high-frequency region, which is likely to cause the mounting bracket 220 to resonate and generate a large vibration noise. However, when the vibration damping foot pad 100 of the present invention is used, since the vibration damping foot pad 100 of the present invention has a good vibration isolation effect, the vibration amplitude transmitted to the mounting bracket 220 is relatively small, thereby more effectively improving the resonance of the mounting bracket 220 and greatly reducing the vibration noise.

[0081] In addition, please refer to Figure 12 and Figure 13 , when comparing the use of the new vibration damping foot pad 100 (the vibration damping foot pad 100 of the present invention) with the use of the original vibration damping foot pad 100 (the traditional vibration damping foot pad 100), after adopting the vibration damping foot pad 100 of the present invention, the vibration amplitude of the mounting bracket 220 is reduced to 1 / 3 of the original, and the peak value of the low-frequency humming sound caused by the wall, etc. is reduced by 11 dB (such as Figure 13 is reduced from 41 dB to 30 dB in

[0082] ), and the vibration feeling and auditory feeling are significantly improved. The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
