The following description is given to enable any technician in the field to implement and use the present application. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, well-known structures and processes will not be elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0027] like Figures 1 to 3 As shown, on the one hand, an embodiment of the present application provides a shock-absorbing foot pad 1, which includes a foot pad body 10, a magnetic core 20 and a conductive spring 30, which can effectively enhance the shock-absorbing effect on the compressor 2, eliminate or at least reduce the vibration noise of the compressor 2 to a large extent.

[0028] The foot pad body 10, as the main structure of the shock-absorbing foot pad 1, can be made of elastic materials such as rubber and silicone, and can absorb the vibration kinetic energy of the compressor 2 by using its own elastic characteristics, thereby reducing the vibration noise of the compressor 2 to a certain extent. The foot pad body 10 can have at least one shock-absorbing direction; when the foot pad body 10 has only one shock-absorbing direction, the shock-absorbing direction is the main shock-absorbing direction of the foot pad body 10; when the foot pad body 10 has multiple shock-absorbing directions, the foot pad body 10 can have one main shock-absorbing direction and at least one auxiliary shock-absorbing direction, and the main shock-absorbing direction is the maximum vibration direction of the shock-absorbing object, that is, the direction in which the shock-absorbing effect of the foot pad body 10 is the strongest.

[0029] The magnetic core 20 and the conductive spring 30 are respectively arranged on the foot pad body 10. The arrangement positions of the magnetic core 20 and the conductive spring 30 on the foot pad body 10 can be determined according to actual needs. For example, they can be respectively arranged inside or on the surface of the foot pad body 10, which is not limited in the embodiment of the present application. The type of the magnetic core 20 can be determined according to actual needs. For example, a permanent magnet, an electromagnet, etc. can be used, and a magnetic field can be generated around the magnetic core 20. The shape of the magnetic core 20 can be determined according to actual needs. For example, a magnetic rod, a magnetic column, etc. can be used. This is not limited in the embodiment of the present application. The extension direction of the magnetic core 20 can be determined according to actual needs. This is not limited in the embodiment of the present application; for example, the magnetic core 20 can extend along the main shock absorption direction of the foot pad body 10.

[0030] The conductive spring 30 is sleeved on the magnetic core 20, and the conductive spring 30 can be elastically deformed along the main shock absorption direction of the foot pad body 10. When the foot pad body 10 has only one shock absorption direction, the shock absorption direction is the main shock absorption direction of the foot pad body 10, and the conductive spring 30 is elastically deformed along the shock absorption direction; when the foot pad body 10 can damp the shock absorption object along multiple shock absorption directions, the foot pad body 10 can have a main shock absorption direction and at least one auxiliary shock absorption direction, and the conductive spring 30 can be elastically deformed along the main shock absorption direction of the foot pad body 10. When the shock-absorbing foot pad 1 is placed at the bottom of a shock absorption object that generates vibration, such as a compressor 2, the main shock absorption direction of the foot pad body 10 can be the up and down direction. The material of the conductive spring 30 can be determined according to actual needs, and can be made of materials such as metals, superconducting materials, etc., which have good elastic deformation performance and conductive performance.

[0031] When a shock-absorbing object such as a compressor 2 is working and vibrates, the vibration will be transmitted to the shock-absorbing foot pad 1. Here, the foot pad body 10 is deformed due to its own elastic characteristics, and part of the vibration kinetic energy is absorbed by elastic deformation; at the same time, the conductive spring 30 is elastically deformed along the main shock-absorbing direction of the foot pad body 10 under vibration drive, on the one hand, part of the vibration kinetic energy is absorbed by the elastic deformation of the conductive spring 30, and on the other hand, the conductive spring 30 is elastically deformed in the magnetic field generated by the magnetic core 20 to generate electromagnetic induction, so that the conductive spring 30 generates an induced current based on electromagnetic induction, and the induced current applies electromagnetic damping to the conductive spring 30 based on Lenz's law. The electromagnetic damping is opposite to the vibration force applied by the shock-absorbing object on the shock-absorbing foot pad 1, so that the elastic deformation of the conductive spring 30 can be hindered and all or at least part of the remaining vibration kinetic energy can be offset. In this way, through the elastic shock-absorbing effect of the foot pad body 10, the elastic shock-absorbing effect of the conductive spring 30, and the electromagnetic damping shock-absorbing effect of the conductive spring 30, the vibration kinetic energy generated by the shock-absorbing object such as the compressor 2 can be completely or at least largely absorbed, effectively enhancing the shock-absorbing effect on the compressor 2, thereby eliminating or at least largely reducing the vibration noise of the compressor 2. It should be supplemented that after the compressor 2 is stopped, the compressor 2 no longer applies vibration to the shock-absorbing foot pad 1, and the conductive spring 30 can be elastically reset.

[0032] In some embodiments, the shock-absorbing foot pad 1 may include a conductive heating element 40, which is disposed on the foot pad body 10, and the conductive heating element 40 is electrically connected to the conductive spring 30. The conductive heating element 40 can generate heat when conducting electricity, and the generated heat is used to heat the foot pad body 10. In this way, when the conductive spring 30 generates an induced current due to the vibration of the shock-absorbing object, the induced current generated by the conductive spring 30 can flow into the conductive heating element 40, so that the conductive heating element 40 conducts electricity and generates heat to heat the foot pad body 10, thereby preventing the foot pad body 10 from hardening in a cold environment with a relatively low temperature, and further preventing the shock-absorbing performance of the foot pad body 10 from being significantly attenuated or completely lost due to the hardening of the foot pad body 10, thereby effectively ensuring the shock-absorbing effect of the shock-absorbing foot pad 1.

[0033] The structure of the conductive heating element 40 can be determined according to actual needs, and the embodiments of the present application do not limit this. In some examples, the conductive heating element 40 can have a spiral extension structure, and the spiral extension structure extends spirally along the axial direction of the mounting through hole 13 to be arranged around the mounting through hole 13. In other examples, the conductive heating element 40 may include a plurality of conductive heating sub-components, and the plurality of conductive heating sub-components are arranged in sequence at intervals, and each conductive heating sub-component is electrically connected to at least one conductive spring 30. The setting position of the conductive heating element 40 on the foot pad body 10 can be determined according to actual needs, and can be set inside the foot pad body 10 or on the surface of the foot pad body 10, and the embodiments of the present application do not limit this.

[0034] In some examples, the shock-absorbing foot pad 1 may include a conductive sheet 60 and a connecting clip 70, and the conductive spring 30, the conductive sheet 60, the connecting clip 70 and the conductive heating element 40 are electrically connected in sequence to conduct the induced current on the conductive spring 30 to the conductive heating element 40 through the conductive sheet 60 and the connecting clip 70.

[0035] In some embodiments, the foot pad body 10 may be provided with a mounting through hole 13 , and the mounting through hole 13 penetrates the foot pad body 10 along the main shock absorption direction of the foot pad body 10 .

[0036] In some examples, the shock-absorbing foot pad 1 and the shock-absorbing object can be fastened to a mounting structure such as the device bottom plate 3 by fasteners penetrating the mounting through holes 13. The type of fastener can be determined according to actual needs, and can be, for example, a fastening screw, a fastening pin, etc., which is not limited in the embodiments of the present application.

[0037] Exemplarily, the foot pad body 10 may include a main body portion 113, a mounting neck 114 and an end flange 115 connected in sequence, and the outer diameter of the main body portion 113 and the outer diameter of the end flange 115 are both larger than the outer diameter of the mounting neck 114; the mounting through hole 13 may include a light hole section 131 and a threaded hole section 132 connected in sequence, the light hole section 131 extends from one end of the main body portion 113 away from the mounting neck 114 to an end of the main body portion 113 close to the end flange 115, and the threaded hole section 132 extends from one end of the main body portion 113 close to the end flange 115 and passes through the mounting neck 114 and the end flange 115. For example, a foot 201 may be provided at the bottom of a shock-absorbing object such as a compressor 2, and a matching through hole may be provided on the foot 201. The matching through hole may be a light hole, and the aperture of the matching through hole may be smaller than the outer diameter of the end flange 115 and the outer diameter of the main body 113, and the aperture of the matching through hole may be greater than or equal to the outer diameter of the mounting neck 114; when the foot pad body 10 and the shock-absorbing object are fastened together, the end flange 115 may be elastically deformed to pass through the matching through hole, so that the foot 201 is clamped on the outer peripheral surface of the mounting neck 114, and the foot 201 is limited by the end flange 115 and the main body 113, so that the foot pad body 10 and the shock-absorbing object are fastened together. When the shock-absorbing object and the shock-absorbing foot pad 1 need to be fixed on a mounting structure such as a device bottom plate 3, a through hole portion may be provided on the mounting structure, and the fastener may pass through the through hole portion, the light hole section 131 in sequence, and then be threadedly connected with the threaded hole section 132, so as to fix the shock-absorbing foot pad 1, the shock-absorbing object, and the mounting structure in sequence.

[0038] In other examples, the pad body 10 and the shock-absorbing object can be fastened and connected by fasteners passing through the mounting through-holes 13. The type of fastener can be determined according to actual needs, and can be, for example, fastening screws, fastening pins, etc., which are not limited in the embodiments of the present application. Here, the mounting through-hole 13 can be a bare hole. Exemplarily, a support foot 201 can be provided at the bottom of a shock-absorbing object such as a compressor 2, and a matching through-hole can be provided on the support foot 201, which can be a threaded hole. When it is necessary to fix the shock-absorbing object and the shock-absorbing pad 1 to a mounting structure such as a base plate 3 of an equipment, a through-hole portion can be provided on the mounting structure, and the fastener can pass through the through-hole portion, the mounting through-hole 13 in sequence, and then be threadedly connected with the matching through-hole to fix the shock-absorbing object, the shock-absorbing pad 1 and the mounting structure in sequence.

[0039] The number of magnetic cores 20 and conductive springs 30 can be determined according to actual needs, and can be one or more, which is not limited in the embodiments of the present application. In some examples, the shock-absorbing foot pad 1 may include multiple magnetic cores 20 and multiple conductive springs 30, and the multiple magnetic cores 20 and multiple conductive springs 30 are respectively arranged in sequence along the circumference of the mounting through hole 13, and each conductive spring 30 is sleeved on a magnetic core 20; when the shock-absorbing foot pad 1 includes the conductive heating element 40 described above, the multiple conductive springs 30 are electrically connected to the conductive heating element 40. Exemplarily, the multiple magnetic cores 20 and the multiple conductive springs 30 are respectively arranged in sequence along the circumference of the mounting through hole 13 and are evenly spaced; and again exemplary, the multiple magnetic cores 20 and the multiple conductive springs 30 are equal in number and arranged one-to-one.

[0040] In some examples, the shock-absorbing foot pad 1 may include the conductive heating element 40 as described above, and the conductive heating element 40 is electrically connected to the conductive spring 30. Exemplarily, the conductive heating element 40 may have a spiral extension structure as described above, extending integrally to cover various areas of the side wall of the mounting through hole 13. Another exemplary embodiment, the conductive heating element 40 may include a plurality of conductive heating sub-elements, and the plurality of conductive heating sub-elements are sequentially spaced along the circumference of the mounting through hole 13, and each conductive heating sub-element is electrically connected to at least one conductive spring 30 to respectively cover various areas of the side wall of the mounting through hole 13.

[0041] The structure of the foot pad body 10 can be determined according to actual needs, and can have an integrated structure or a split structure, which is not limited in the embodiments of the present application. In some embodiments, the foot pad body 10 can have a split structure, correspondingly including an upper pad body 11 and a lower pad body 12. The upper pad body 11 and the lower pad body 12 can approach or move away from each other along the main shock absorption direction of the foot pad body 10, the magnetic core 20 slidably connects the upper pad body 11 and the lower pad body 12, and the conductive spring 30 elastically connects the upper pad body 11 and the lower pad body 12. Exemplarily, when the foot pad body 10 is provided with the above-mentioned mounting through hole 13, the mounting through hole 13 can be formed on the upper pad body 11 and the lower pad body 12 respectively. Exemplarily, the above-mentioned main body 113, the mounting neck 114 and the end flange 115 can be formed on the upper pad body 11.

[0042] Exemplarily, the upper pad 11 can be connected to the support of the damping object, and the lower pad 12 can be connected to the support of the mounting structure. When the foot pad body 10 is subjected to vibration compression of the damping object such as the compressor 2, the upper pad 11 can slide close to the lower pad 12 under the action of vibration, so as to utilize the sliding action and the elastic damping action of the upper pad 11 to buffer and absorb the vibration of the compressor 2; the upper pad 11 further slides to the end of the stroke to directly press against the lower pad 12, or further slides to the end of the stroke to press against the end of the magnetic core 20, so that the upper pad 11 is indirectly pressed against the lower pad 12 through the magnetic core 20, and the lower pad 12 directly or indirectly supports the upper pad 11 through the magnetic core 20, so as to further buffer and absorb the vibration of the compressor 2. In this process, the conductive spring 30 can elastically deform to produce the above-mentioned elastic damping action and electromagnetic damping action, so as to absorb the vibration kinetic energy generated by the damping object such as the compressor 2, and effectively enhance the damping effect on the compressor 2.

[0043] After the compressor 2 stops, the compressor 2 no longer applies vibration to the shock-absorbing foot pad 1, and the conductive spring 30 can be elastically reset to separate the upper pad 11 and the end of the magnetic core 20 or the lower pad 12 and return to the original position.

[0044] In some examples, the upper pad 11 may have a top and a lower mating portion 111 that are arranged opposite to each other, and the lower pad 12 may have an upper mating portion 121 and a lower supporting portion 122 that are arranged opposite to each other, and the lower mating portion 111 is used to abut and support the upper mating portion 121. The upper mating portion 121 and the lower supporting portion 122 may be arranged obliquely, and the lower mating portion 111 and the upper mating portion 121 may be arranged in parallel. In this way, the abutting support area between the upper pad 11 and the lower pad 12 may be increased to a large extent, and the buffer support reliability between the upper pad 11 and the lower pad 12 may be significantly enhanced.

[0045] Exemplarily, an upper mounting cavity 112 may be provided inside the upper pad body 11, and a lower mounting cavity 123 may be provided inside the lower pad body 12. The number of upper mounting cavities 112 and lower mounting cavities 123 may be determined according to actual needs, and the embodiments of the present application do not limit this; Exemplarily, a mounting through hole 13 and a plurality of upper mounting cavities 112 may be provided inside the upper pad body 11, and a mounting through hole 13 and a plurality of lower mounting cavities 123 may be provided inside the lower pad body 12, and the plurality of upper mounting cavities 112 may be arranged in sequence along the circumference of the mounting through hole 13, and the plurality of lower mounting cavities 123 may be arranged in sequence along the circumference of the mounting through hole 13. One end of the magnetic core 20 may be slidably disposed in one of the upper mounting cavity 112 and the lower mounting cavity 123 along the main shock absorbing direction of the foot pad body 10, and the other end may be fixed in the other of the upper mounting cavity 112 and the lower mounting cavity 123. For example, one end of the magnetic core 20 can be slidably disposed in the upper mounting cavity 112 along the main shock absorption direction of the foot pad body 10, and the other end is fixed in the lower mounting cavity 123; for another example, one end of the magnetic core 20 can be slidably disposed in the lower mounting cavity 123 along the main shock absorption direction of the foot pad body 10, and the other end is fixed in the upper mounting cavity 112. The two ends of the conductive spring 30 are respectively embedded in the upper mounting cavity 112 and the lower mounting cavity 123 to elastically connect the upper pad body 11 and the lower pad body 12. By the above arrangement, the magnetic core 20 and the conductive spring 30 can be at least partially embedded in the foot pad body 10, so that the structure of the shock-absorbing foot pad 1 is relatively compact and small.

[0046] Exemplarily, the shock-absorbing foot pad 1 may include a check ring 50; the check ring 50 is used to separate one of the upper mounting cavity 112 and the lower mounting cavity 123 into a first sub-cavity portion 1121 and a second sub-cavity portion 1122, and the first sub-cavity portion 1121 and the second sub-cavity portion 1122 are connected in sequence along the main shock-absorbing direction of the foot pad body 10. For example, the check ring 50 can be arranged in the upper mounting cavity 112 to separate the upper mounting cavity 112 into a first sub-cavity 1121 and a second sub-cavity 1122, the first sub-cavity 1121 and the second sub-cavity 1122 are connected in sequence along the main shock-absorbing direction of the foot pad body 10, the first sub-cavity 1121 opens on the surface of the upper pad body 11, and the second sub-cavity 1122 is formed at the bottom of the upper mounting cavity 112; for another example, the check ring 50 can be arranged in the lower mounting cavity 123 to separate the lower mounting cavity 123 into a first sub-cavity 1121 and a second sub-cavity 1122, the first sub-cavity 1121 and the second sub-cavity 1122 are connected in sequence along the main shock-absorbing direction of the foot pad body 10, the first sub-cavity 1121 opens on the surface of the lower pad body 12, and the second sub-cavity 1122 is formed at the bottom of the lower mounting cavity 123. The non-return ring 50 can be integrally formed on the upper cushion body 11 or the lower cushion body 12 , or can be separately formed and then embedded in the upper mounting cavity 112 or the lower mounting cavity 123 .

[0047] Here, the magnetic core 20 may include a magnetic core body 21 and a non-return flange 22 disposed at one end of the magnetic core body 21. The non-return flange 22 is slidably disposed in the second sub-cavity 1122, and the magnetic core body 21 passes through the first sub-cavity 1121 and is connected to the non-return flange 22, and the non-return retaining ring 50 is used to prevent the non-return flange 22 from being separated from the second sub-cavity 1122. Taking the check ring 50 dividing the upper mounting cavity 112 into the first sub-cavity 1121 and the second sub-cavity 1122 as an example, when the upper pad 11 is subjected to vibration pressure of a damping object such as the compressor 2, the upper pad 11 can first slide close to the check flange 22 under the action of vibration, and in this process, the vibration of the compressor 2 is buffered and absorbed by the sliding action and the elastic damping action of the upper pad 11; the upper pad 11 can further slide until it is pressed against the check flange 22, and the lower pad 12 indirectly elastically supports the upper pad 11 through the magnetic core 20, so as to further buffer and absorb the vibration of the compressor 2. Exemplarily, when the upper pad 11 / lower pad 12 and the check flange 22 are pressed against each other, the upper pad 11 and the lower pad 12 are spaced apart and do not contact each other.

[0048] On the other hand, an embodiment of the present application provides an air conditioner, which includes a compressor 2 and a shock-absorbing foot pad 1 provided in any of the above embodiments.
