DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, Figures 1-4 As shown, the damping device for reducing the vibration of the iron core includes a plurality of iron cores 100, epoxy plates 101, conductive rings 102 and iron core columns 103. An iron core column 103 is provided in the middle of the iron core 100, an epoxy plate 101 is provided at each end of the opposite surface of the iron core 100, a conductive ring 102 is provided on the epoxy plate 101, clip assemblies 200 are provided on both sides of the epoxy plate 101, and a buffer assembly 300 is provided on the epoxy plate 101;

[0027] When in use, the conductive ring 102 is placed on the top of the lower epoxy plate, and then the circular protrusion 304 at the bottom of the upper epoxy plate is aligned with the circular groove 303 at the top of the lower epoxy plate and inserted. At the same time, the two epoxy plates 101 are spliced ​​and firmly connected through the snap assemblies 200 on both sides of the epoxy plate 101, so that the conductive ring 102 is stabilized between the two epoxy plates 101. The conductive ring 102 will use the characteristics of the alternating magnetic field brought by the inductor itself to generate a damping force. The damping force generated by the conductive ring 102 and the vibration of the inductor itself offset each other to achieve the effect of eliminating vibration, thereby achieving a noise reduction effect. At the same time, the conductive ring 102 is added between the upper and lower epoxy plates 101 to reduce vibration and noise, with low production cost and simple production process.

[0028] In one embodiment, Figure 3 As shown, the epoxy board 101 is made of insulating material, and the epoxy board 101 is divided into an upper epoxy board and a lower epoxy board;

[0029] When in use, the epoxy plate 101 is an insulating material that can isolate the upper and lower iron cores 100 to avoid special situations such as leakage. At the same time, the upper and lower epoxy plates 101 can better and firmly place the conductive ring 102 between the epoxy plates 101, and facilitate the subsequent disassembly and inspection of the subsequent iron core inductor.

[0030] In one embodiment, Figure 4As shown, the snap assembly 200 includes a spring 201, a connecting block 202, a push block 203, a protrusion 204, a protrusion 205 and a groove 206. The protrusions 204 are provided on both sides of the upper epoxy plate, the spring 201 is provided in the protrusion 204, the connecting block 202 is fixedly connected to one side of the spring 201, the push block 203 is fixedly connected to the connecting block 202 on one side, the protrusion 205 is fixedly connected to the bottom end of the connecting block 202 on one side, and the other side passes through the lower end of the protrusion 204. The grooves 206 are provided on both sides of the lower epoxy plate, and the grooves 206 correspond to the protrusions 205;

[0031] When in use, push the push block 203 outward to move the protrusion 205 into the protrusion 204. The movement of the protrusion 205 will drive the connecting plate 202 to move the compression spring 201. When the protrusion 205 moves into the protrusion 204, install the upper epoxy plate on the lower epoxy plate so that the position of the protrusion 205 is aligned with the position of the groove 206. Then release the push block 203, so that the protrusion 205 bounces into the groove 206 under the action of the spring 201, completing the fixed installation of the epoxy plate 101.

[0032] In one embodiment, Figure 3 As shown, the buffer assembly 300 includes a rubber ring 301, a rubber block 302, a circular groove 303 and a circular protrusion 304. The circular groove 303 is provided at the top of the lower epoxy plate, and the circular protrusion 304 is provided at the bottom of the upper epoxy plate. Rubber rings 301 are provided on both sides of the circular groove 303, and a rubber block 302 is provided at the bottom of the circular groove 303.

[0033] During use, when installing the epoxy plate 101, align the circular protrusion 304 at the bottom end of the upper epoxy plate with the circular groove 303 at the top end of the lower epoxy plate and insert it so that the circular protrusion 304 enters the circular groove 303. The rubber ring 301 inside the circular groove 303 will have a certain fixing effect on the circular protrusion 304. At the same time, when the inductor is working, the rubber ring 301 inside the circular groove 303 and the rubber block 302 at the bottom can buffer the vibration of the epoxy plate 101, preventing the epoxy plate 101 and the iron core 100 from vibrating violently and making noise.

[0034] In one embodiment, Figure 1-Figure 3 As shown, the height of the circular protrusion 304 plus the height of the rubber block 302 is greater than the depth of the circular groove 303;

[0035] When in use, the height of the circular protrusion 304 plus the height of the rubber block 302 is greater than the height of the circular groove 303. When the inductor is working, there will be a gap between the upper and lower epoxy plates 101. The gap, together with the buffer component 300, can prevent the epoxy plate 101 from making noise due to the vibration of the inductor, thereby achieving an effective buffering effect.

[0036] In one embodiment, Figure 3As shown, the conductive ring 102 is conductive but not magnetic;

[0037] When in use, the conductive ring 102 is not conductive and cannot be magnetic, so that the conductive ring 102 can generate a damping force opposite to the vibration of the silicon steel sheets in the iron core to suppress the noise problem caused by the vibration of the silicon steel sheets inside the iron core 100.

[0038] In one embodiment, Figure 3 As shown, a rubber pad is provided on the inner surface of the groove 206;

[0039] During use, the rubber pad on the inner surface of the groove 206 can also provide a buffering effect for the epoxy plate 101 and the conductive ring 102 .

[0040] In one embodiment, Figure 1-Figure 3 As shown, the diameter of the epoxy plate 101 is equal to the diameter of the iron core 100, and the diameter of the conductive ring 102 is smaller than the diameter of the epoxy plate 101;

[0041] When in use, the diameter of the epoxy plate 101 is equal to the diameter of the iron core 100 and the diameter of the conductive ring 102 is smaller than the diameter of the epoxy plate 101 to ensure that the conductive ring 102 does not contact the upper and lower iron cores 100, and at the same time will not affect the fixed installation of the epoxy plate 101.

[0042] The working principle of the present invention is as follows: when in use, the conductive ring 102 is placed on the top of the lower epoxy plate, and then the circular protrusion 304 at the bottom end of the upper epoxy plate is aligned with the circular groove 303 at the top end of the lower epoxy plate and inserted, and the rubber ring 301 inside the circular groove 303 will have a certain fixing effect on the circular protrusion 304. At the same time, when the inductor is working, the rubber ring 301 inside the circular groove 303 and the rubber block 302 at the bottom end can buffer the vibration of the epoxy plate 101, preventing the epoxy plate 101 and the iron core 100 from vibrating violently and making noise. Then, the pushing block 203 is pushed outward to move the protrusion 205 into the protrusion 204. The movement of the protrusion 205 will drive the connecting plate 202 to move the compressed spring 201. When the protrusion 205 moves into the protrusion 204, the upper epoxy plate is installed on the lower epoxy plate so that the position of the protrusion 205 is aligned with the position of the protrusion 205. The grooves 206 are aligned, and then the push block 203 is released, so that the protrusion 205 bounces into the groove 206 under the action of the spring 201, completing the fixed installation of the epoxy plate 101. When the inductor needs to be checked later, the snap assembly 200 can also be used to more conveniently complete the disassembly and inspection. After installation, there is a gap between the two epoxy plates 101. The gap cooperates with the buffer assembly 300 to better buffer the epoxy plate 101 and the conductive ring 102. At the same time, the rubber pad on the inside of the groove 206 that matches the protrusion 205 can also play a buffering role. The conductive ring 102 between the epoxy plates 101 will use the characteristics of the alternating magnetic field brought by the inductor itself to generate a damping force. The damping force generated by the conductive ring 102 and the vibration of the inductor itself offset each other to achieve the effect of eliminating vibration and reduce the operating noise of the inductor.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application.
