  • Patent number: 11293175
    Abstract: A self-resetting tuned mass damper is based on eddy current and shape memory alloy technology. The self-resetting tuned mass damper comprises a hollow box, a cover plate, a bolt, a mass block, gears a, gears b, gears c, copper sheets, permanent magnet groups, partition boards, balls, pins, levers, shape memory alloys, rotating shafts a, rotating shafts b, a supporting plate and rotating shafts c. The movement of the mass block causes the copper sheets to rotate and generate eddy current for energy consumption. The copper sheets are rotated and amplified by adjusting the sizes of the gears. The displacement of a small mass block can cause rotation of the copper sheets by a large angle, which greatly increases energy consumption efficiency. The elongation of the shape memory alloys is amplified by adjusting the ratio of long and short force arms of the levers.

  • Publication number: 20220102237
    Abstract: Embodiments of this application provide a chip and a manufacturing method thereof, and an electronic device, and belong to the field of chip heat dissipation technologies. The chip includes a die and a thermal conductive sheet. An active surface of the die is connected to the thermal conductive sheet by using a first bonding layer. Heat generated at a part with a relatively high temperature on the active surface of the die can be quickly conducted and dispersed by using the thermal conductive sheet, so that temperatures on the active surface are evenly distributed to avoid an excessively high local temperature of the chip, thereby preventing running of the chip from being affected.

The coupling beam eddy current damper with shear displacement amplification comprises a rigid rod, rotating shafts, a pin column, pins, levers, screws, thread sleeves, copper sheets, permanent magnet components, a steel structural component, balls, ball supports and an outer shell. When vibration occurs, coupling beams on both sides of the damper are relatively vertically displaced; at this moment, two levers move up and down relative to the rigid rod; the movement causes the screws and the copper sheets to rotate; the copper sheets rotate in a magnetic field, then induced electromotive force will generates inside the magnetic field, thereby generating eddy current in the copper sheets. The eddy current effect will produce a damping force that impedes the rotation of the copper sheets.

  • Publication number: 20210115999
    Abstract: An axial displacement amplified eddy current damper is disclosed. The axial movement of a slide bar is converted into the rotation of copper sheets and generates eddy current for energy consumption. The copper sheets are rotated and amplified by adjusting the sizes of gears. The short displacement of the slide bar can cause a large angle rotation of the copper sheets, so that energy consumption efficiency is high. The damping parameter can be adjusted by adjusting the magnetic field strength of permanent magnets, the thickness of the copper sheets and the distance from the copper sheets to the permanent magnets. The permanent magnets are adopted to provide continuous magnetic field sources, without external energy, thereby generating long-term and stable vibration reduction effect.
