The terms used in the specification of the present application herein are only for the purpose of describing the specific embodiments and are not intended to limit the present application.
[0042] Example 1:
[0043] Please refer to Figures 1 to 4The embodiment provides a damping and noise reduction foot pad 100 for solving the problems of vibration and noise of an electrical equipment, for example, vibration and noise generated by a compressor and a fan during operation of an air conditioning system. The damping and noise reduction foot pad 100 mainly comprises a foot pad main body 1 and a connecting portion 2 arranged at the center of the foot pad main body 1, and the foot pad main body 1 and the connecting portion 2 are integrally formed.
[0044] Specifically, the damping and noise reduction foot pad 100 is provided with a fixed end 10 for abutting against an external base and a connecting end 11 for connecting with an electrical equipment, and the connecting end 11 and the fixed end 10 are arranged at two ends of the damping and noise reduction foot pad 100. The external base can be a ground, a wall, a supporting plate or the like for placing or supporting the damping and noise reduction foot pad 100 and the electrical equipment connected therewith. In the embodiment, the damping and noise reduction foot pad 100 is approximately cylindrical as a whole, and the fixed end 10 is designed in a plane shape to increase the contact area with the base and improve the stability.
[0045] The foot pad main body 1 is provided with a receiving groove 12 extending from the connecting end 11 to the fixed end 10 and arranged around the connecting portion 2. The receiving groove 12 is provided with an opening 121 at the connecting end 11, and a filling piece 13 is detachably connected in the receiving groove 12. The filling piece 13 is matched with the receiving groove 12, and the outer side wall of the filling piece 13 abuts against the inner side wall of the receiving groove 12. Through cooperation between the filling piece 13 and the foot pad main body 1, the damping and noise reduction foot pad 100 can offset the inherent modal of the electrical equipment connected therewith, so as to reduce resonance, improve vibration and reduce noise, and help to meet the current market demand for noise reduction and vibration reduction of electrical equipment. In addition, the opening 121 of the receiving groove 12 facilitates replacement of the filling piece 13 with different hardness, and the filling piece 13 with different materials can be selected according to the inherent modal frequency of the external equipment connected therewith, so as to improve the universality of the damping and noise reduction foot pad 100.
[0046] In summary, the structure of the damping and noise reduction foot pad 100 is helpful to face the complex and changeable vibration and noise problems, and is suitable for different stress conditions and frequency responses.
[0047] For reference Figure 4 In the embodiment, a groove 131 is formed in the outer side of the filling piece 13 in a radial direction, and a protrusion 132 is formed on the filling body, and the protrusion 132 abuts against the inner side wall of the receiving groove 12. Specifically, the groove 131 penetrates through the outer side of the filling piece 13 in the direction from the connecting end 11 to the fixed end 10, and forms a strip-shaped groove 131. Correspondingly, the protrusion 132 is formed on the outer side of the filling piece 13 and is arranged in a spaced manner with the groove 131, and the protrusion 132 abuts against the inner side wall of the receiving groove 12.
[0048] Further, the connecting portion 2 is provided with a locking through groove 21 extending from the connecting end 11 to the fixing end 10, which is used to cooperate with the bolt of the external device to achieve the locking connection between the vibration and noise reduction foot pad 100 and the device.
[0049] In some embodiments, the connecting portion 2 can also be protruded relative to the opening 121, and the filler 13 is flush with the opening 121, while the connecting portion 2 and the opening 121 are formed with a clamping groove 22 for fixing the external device, and the size of the clamping groove 22 is matched with the clamping structure of the bottom of the device. When installed, the vibration and noise reduction foot pad 100 is connected with the external device through the locking through groove 21, and at the same time, the clamping structure of the external device can be clamped into the clamping groove 22, thereby further improving the stability of the connection between the vibration and noise reduction foot pad 100 and the external device, and reducing the noise caused by weak stability. In this embodiment, the top end of the connecting portion 2 is protruded outward along the circumference to form a rim structure, and the clamping groove 22 is formed between the lower part of the rim structure and the opening 121.
[0050] Preferably, the clamping groove 22 is provided on the connecting portion 2, and is closer to the center line of the vibration and noise reduction foot pad 100 than the position accommodating groove 12, so that when the clamping structure of the external device is clamped to the connecting portion 2, the clamping structure can cover the opening 121 of the accommodating groove 12 to limit the filler 13, preventing the filler 13 from falling off easily.
[0051] Further, the accommodating groove 12 extends in the direction from the connecting end 11 to the fixing end 10, and the accommodating groove 12 is in a closed structure at the end away from the opening 121, thereby avoiding the bottom of the filler 13 from directly contacting the ground or other base, and ensuring that the vibration and noise reduction foot pad 100 achieves the ideal effect in reducing noise and improving vibration.
[0052] Further, the foot pad body 1 is provided with a first step portion 14 and a second step portion 15 arranged in a layered stack, and the first step portion 14 and the second step portion 15 are elastically connected to play a buffering role, which helps to face external forces in different directions and improves the vibration reduction effect of the vibration and noise reduction foot pad 100. At the same time, the fixing end 10 of the foot pad body 1 is the second step portion 15, so that the foot pad body 1 as a whole has an upper narrow and lower wide structure, which increases the area of the foot pad body 1 abutting against the external base and improves the stability. In this embodiment, the foot pad body 1 is formed by one layer of the first step portion 14 close to the connecting end 11 and one layer of the second step portion 15 close to the fixing end 10. Preferably, the foot pad body 1 is made of silica gel, rubber or other materials that can realize elastic displacement to achieve the elastic connection between the first step portion 14 and the second step portion 15. Preferably, the first step portion 14 and the second step portion 15 are connected by a slope, and the slope extends upward from the outside of the second step portion 15 to the outside of the first step portion 14.
[0053] In some embodiments, the foot pad body 1 is stacked with a plurality of second step portions 15 and first step portions 14 in the vertical direction. In the case of external vibration or other forces, the first step portions 14 elastically displace relative to the second step portions 15, thereby offsetting the external forces and playing a buffering role to reduce the impact of vibration on the equipment and further reduce noise.
[0054] Preferably, the second step portion 15 is an arc-shaped structure recessed towards the center line of the foot pad body 1. The recessed depth of the second step portion 15 gradually decreases in the direction from the connecting end 11 to the fixed end 10, and the fixed end 10 is the first step portion 14. This makes the center of gravity of the vibration and noise reduction foot pad 100 close to the fixed end 10, and makes the stability of the fixed end 10 most stable, further improving the problems of vibration and noise.
[0055] Embodiment 2
[0056] The difference between this embodiment and Embodiment 1 is the structure of the filler 13. The differences of Embodiment 2 are described in detail below, and the same parts are referred to Embodiment 1.
[0057] Please refer to Figure 5 In this embodiment, the filler 13 is a spring member spirally extending around the accommodating groove 12. Preferably, the spring member is made of high-strength metal material, which has good elasticity and restoring force. In some embodiments, the pitch of the spring member can also be adjusted to effectively absorb vibration energy while ensuring sufficient elasticity, thereby further improving the overall vibration and noise conditions.
[0058] Embodiment 3
[0059] The difference between this embodiment and Embodiment 1 is the structure of the filler 13. The differences of Embodiment 3 are described in detail below, and the same parts are referred to Embodiment 1.
[0060] As Figure 6 shown, in this embodiment, the filler 13 is a ring-shaped cylindrical structure as a whole, and the filler 13 is embedded in the accommodating groove 12. The outer side wall of the filler 13 abuts against the inner side wall of the accommodating groove 12, and the inner side wall of the filler 13 abuts against the outer periphery of the connecting portion 2. Preferably, the filler 13 is a rubber member, which has good damping characteristics and can effectively suppress the propagation of noise while absorbing vibration energy.
[0061] Embodiment 4
[0062] On the basis of the above-mentioned embodiments, this embodiment provides an electrical appliance system 200, which includes an equipment body 3 and a vibration and noise reduction foot pad 100. This embodiment takes the equipment body 3 as a compressor as an example to describe the electrical appliance system 200 in detail.
[0063] Please refer to Figures 7-8 The damping and noise reduction foot pad 100 of the embodiment adopts the damping and noise reduction foot pad 100 in embodiment 1. The bottom of the compressor is uniformly provided with three mounting portions 31, the mounting portion 31 comprises a clamping body 311, and the central portion of the clamping body 311 is provided with a mounting through hole 312. The connecting portion 2 of the damping and noise reduction foot pad 100 passes through the mounting through hole 312, so that the mounting through hole 312 is fixed with the bolt of the compressor. At the same time, the edge of the clamping body 311 close to the mounting through hole 312 is inserted into the clamping groove 22 and covers the top of the opening 121, which further improves the stability of the connection between the damping and noise reduction foot pad 100 and the compressor.
[0064] The compressor may generate vibration and noise during operation. Under the action of the damping and noise reduction foot pad 100 with the appropriate filler 13, the fixed frequency point of the whole electric appliance system 200 is changed, which helps to reduce the resonance amplitude, optimize the vibration state, finally reduce the generation of noise, and significantly improve the comfort of the ear part.
[0065] The above is only an example and description of the structure of the utility model, which is more specific and detailed, but it cannot be understood as a limitation on the scope of the utility model patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, and these obvious alternative forms belong to the protection scope of the utility model.
