An adjustable permanent magnet shock absorber

Abstract

The invention discloses an adjustable permanent magnet shock absorbing device, which comprises two fixed seats up and down. A rotating shaft is movably installed on the fixed seats. The end of the rotating shaft away from the adjusting knob is fixedly connected with the driving gear. A permanent magnet is installed, and the permanent magnet is movably installed in the adjustment seat, and a rotating seat is movably installed at both ends of the adjusting seat, and a matching permanent magnet is fixedly installed on the rotating seat, and the upper and lower two matching permanent magnets pass through the limit The position groove is connected, and a rubber telescopic air cushion is fixedly installed between the upper and lower fixed seats, and a shock absorbing spring is fixedly installed between the upper and lower fixed seats. The present invention adopts three kinds of shock absorbers: spring, air bag and permanent magnet Vibration absorption can be achieved without electrification, and the inclined arrangement structure can prevent the wear caused by the friction between the magnet and the inner wall. The position of the permanent magnet can also be adjusted to adjust the shock absorption strength of the device, which is suitable for various vibrations. environment, suitable for widespread promotion.

Description

technical field [0001] The invention relates to the technical field of shock absorbing devices, in particular to an adjustable permanent magnet shock absorbing device. Background technique [0002] A shock absorbing device with the application number of "CN201711098452.8" in the prior art includes a main shock absorbing device, and buffer devices are provided at both ends of the main shock absorbing device; the main shock absorbing device includes a sleeve, and the Both sides of the sleeve pipe wall are symmetrically provided with travel grooves, and the inner two ends of the sleeve are respectively provided with a first electromagnet and a second electromagnet, and the first electromagnet and the second electromagnet are arranged concentrically. And the polarities of the first electromagnet and the second electromagnet repel each other, and the two side walls of the first electromagnet and the second electromagnet are all symmetrically fixedly connected with connecting rods...

AI Technical Summary

Problems solved by technology

[0003] But above-mentioned this shock-absorbing device still has comparatively obvious defective in use: 1, above-mentioned device utilizes spring and magnet as shock-absorbing device, and shock-absorbing effect is limited; Electric energy is contrary to the current concept of energy saving and environmental protection; 3. The magnets of the above device are placed opposite to each other for shock absorption. Under high pressure, the magnets placed opposite are easy to shift to one side, so that the electromagnet and the sleeve Friction occurs, which will easily lead to wear of the electromagnet in the long run
