Magnetofluid clock

Abstract

The invention discloses a magnetofluid clock which comprises four clock digital display units. Each digital display unit comprises a bottom plate and a front panel in parallel, wherein seven motors are installed on the bottom plate, a lead screw is fixedly installed on a rotary shaft of each motor, a strip-type linkage plate is installed on each lead screw, the two ends of each linkage plate are arranged on two guide pillars fixed to the bottom plate in a sleeving mode respectively, the seven linkage plates are arranged in an 8 shape, and all the linkage plates are provided with electromagnets; magnetofluid is placed in the front panel, and the linkage plates are driven by the motors to move forwards or backwards; when the linkage plates move forwards, the electromagnets on the linkage plates attract the magnetofluid; when the linkage plates move backwards, the magnetofluid is released and returns to the original position. According to the magnetofluid clock, an electronic part and a mechanical part are combined; firstly, the advantages of the electronic part that timing is accurate and the number of time errors is extremely small are utilized in cooperation with the mechanical part, digits are displayed by attracting the magnetofluid, the display effect is rich, and more interestingness is achieved.

Description

technical field [0001] The invention relates to a clock, in particular to a magnetofluid clock combining electronics and machinery. Background technique [0002] At present, the clocks on the market are generally divided into electronic screen display or purely mechanical clock design. These two designs have their own advantages and disadvantages. The electronic clock display is accurate and cheap, but the time display effect is relatively simple, and the pure mechanical clock is easy. There will be a phenomenon that the timing is not accurate enough. [0003] Ferrofluid is a magnetic liquid that can change shape and position by magnetic force. There is a magnetic field component inside, that is, a magnet driven by a motor. By turning on or off the magnetic field, the ferrofluid can be attracted to the position you want to display, and combined to form individual numbers on the clock. In addition, since the ferrofluid itself has weight, it will be dragged to the bottom of ...
