Technical Field

[0001] The invention belongs to the technical field of magnetic fluid display, and in particular relates to a magnetic fluid clock adopting a bidirectional self-deflecting magnet fixing structure. Background Art

[0002] As a time measurement tool, clocks play an indispensable and important role in daily life and industrial applications. Traditional clocks are generally divided into mechanical clocks and electronic clocks. A mechanical clock is a device that measures time through a mechanical device. Its structure is very complex. Its working principle is based on a series of mechanical parts that cooperate with each other. It is powered by a spring or a heavy hammer, and the power is transmitted by a gear system. The escapement controls the periodic release of the gears, and the balance wheel provides oscillation control rhythm. Finally, the time is indicated by the hour hand, minute hand and second hand; an electronic clock is a device that uses electronic technology to time. Its working principle is usually to use a quartz crystal oscillator as a time reference. The quartz crystal generates a stable oscillation frequency under the action of voltage. This frequency is used to realize the clock timing function, which can be a digital display or an analog pointer type. Between the precise mechanical structure of a mechanical clock and the precise electronic oscillation of an electronic clock, the present invention creates a new magnetic fluid clock through intelligent magnetic nanomaterials and unique non-contact adsorption display technology. The existing technology discloses some invention patents in the field of magnetic fluid clock display technology. Among them, the utility model patent with application number CN201920983812.0 discloses a bidirectional self-holding telescopic electromagnet fixing structure of a magnetic fluid clock. The device is used to install the telescopic electromagnet of the magnetic fluid clock, and provides an electromagnet fixing structure. However, the frequent extension and retraction of the electromagnet and the lead screw may cause wear and affect long-term durability. The utility model patent with application number CN201720591416.4 discloses a permanent magnet magnetic fluid clock, which uses a circuit PCB board as a control circuit to control the rotation of the stepper motor to move the permanent magnet back and forth, thereby controlling the external magnetic field to control the morphology of the magnetic fluid and realize pattern display. However, multiple components are integrated on the PCB board, which may cause heat dissipation problems in the sealed housing. The utility model patent with application number CN201621082975.4 discloses a magnetic fluid clock, which converts rotation into linear motion through a screw installed on the motor shaft, so that the electromagnet on the linkage plate moves back and forth, attracting the magnetic fluid to display numbers, but the motor needs to accurately control the position of the electromagnet on the linkage plate, which requires complex algorithms and drivers. The utility model patent with application number CN202122320954.9 discloses a magnetic fluid digital controller, which provides a permanent magnet push-pull device that can control multiple permanent magnets that absorb magnetic fluid, but it is necessary to accurately control the position and magnetic pole direction of each permanent magnet, which may be difficult in actual operation. The utility model patent with application number CN201720361272.3 discloses a liquid digital clock, which controls the magnetic part to make a linear reciprocating motion, so that the magnetic part is close to the liquid display screen to display the liquid digital clock, but does not provide a method for accurately controlling the interaction between the magnetic part and the fluid to achieve a clear display.The utility model patent with application number CN201620030546.6 discloses a magnetic fluid digital display clock. The device controls the magnetic field through a magnetic field controller. The magnetic fluid in the time display is controlled by the magnetic field to display digital time, but it does not mention how to accurately control the magnetic field to make the magnetic fluid display digital time. The invention patent with application number CN201710976644.8 discloses a magnetic fluid time display color screen clock controlled by a magnetic control position push-pull electromagnet. The magnetic fluid is controlled by a magnetic control position push-pull electromagnet to display time, but frequent operation may cause wear of the core component, overheating of the electromagnetic coil, and weakening of the magnetic force of the permanent magnet. So far, although there are many magnetic fluid clock schemes, most of them have a single structure, a large volume, low innovation, and certain limitations and defects. To this end, the present invention designs a magnetic fluid clock with a bidirectional self-deflecting magnet fixed structure. The magnetic fluid clock of the present invention has achieved innovation in technology with its unique intelligent nanomaterials and non-contact adsorption display technology, as well as the designed bidirectional self-deflecting magnet fixed structure and the integrated time reading and signal processing control scheme, and provides unprecedented visual enjoyment in user experience. Summary of the invention

[0003] The purpose of the present invention is to provide a new type of magnetic fluid display technology, including but not limited to magnetic fluid clocks, and is also applicable to other magnetic fluid display technologies.

[0004] To achieve the above object, the technical solution of the present invention is: a magnetic fluid clock using a bidirectional self-deflecting magnet fixing structure, the device includes a magnet deflection device, a steering gear fixing plate, a magnetic fluid display screen and a clock housing. The steering gear fixing plate is placed in the clock housing, the magnet deflection device is installed on the steering gear mounting groove of the steering gear fixing plate, and the magnetic fluid display screen is placed in the clock housing and in front of the magnet deflection device.

[0005] The magnet deflection device includes a magnet, a bidirectional self-deflecting magnet fixing plate, a servo deflection pointer plate, and a servo, wherein the servo deflection pointer plate is installed on the servo output shaft, and the servo deflection pointer plate is rotated by the rotational motion output by the servo, a mounting groove is designed on the back of the bidirectional self-deflecting magnet fixing plate, the mounting groove matches the size of the servo deflection pointer plate, the mounting groove and the servo deflection pointer plate are connected by a card slot, and a groove is designed on the front of the bidirectional self-deflecting magnet fixing plate, and a magnet is installed in the groove.

[0006] The servo fixing plate is designed with a servo mounting slot for installing the servo, and the size of the servo mounting slot matches the size of the servo. The servo mounting slots are arranged in a "double cross shape", and each servo and servo mounting slot are connected by a card slot.

[0007] The shape of the magnetic fluid display screen is a rectangular hollow groove, which is used to store magnetic fluid. The magnetic fluid display screen is placed in the clock case. As a screen for clock display, the size of the magnetic fluid display screen is slightly smaller than the clock case to facilitate installation in the clock case.

[0008] The clock housing is designed to package the entire clock part, protect the internal clock components and provide necessary structural support, including a magnetic fluid display screen, a magnet, a bidirectional self-deflecting magnet fixing plate, a servo deflection pointer plate, a servo and a servo fixing plate.

[0009] The control scheme of the present invention is described below: the present invention can use an Arduino chip as a control center, read the current time through a DS1302 clock module, and transmit the time signal read by the DS1302 clock module to the Arduino chip, and the Arduino chip converts the obtained time signal to a PCA9685 servo drive module. The PCA9685 servo drive module can control 28 servos to rotate. The PCA9685 servo drive module can be used to perform precise angle control and current regulation on the servos, thereby completing the present invention.

[0010] When the whole machine is working, the magnetofluid clock is composed of and represented by four digits as a whole. Each digit is represented by a magnet attracting the magnetofluid in the magnetofluid display screen. The magnet is installed on a two-way self-deflecting magnet fixing plate. The two-way self-deflecting magnet fixing plate is connected to the servo through a servo deflection pointer plate. The servo is installed and arranged in the shape of a number "8" on the servo fixing plate. The servo drives the servo deflection pointer plate to rotate, thereby driving the magnet on the two-way self-deflecting magnet fixing plate to deflect. When the two-way self-deflecting magnet fixing plate is deflected to a plane, the magnet in the groove on the front side of the two-way self-deflecting magnet fixing plate will attract the magnetofluid in the magnetofluid display screen. When the two-way self-deflecting magnet fixing plate is deflected to the side, the magnet in the groove on the front side of the two-way self-deflecting magnet fixing plate will not attract the magnetofluid in the magnetofluid display screen, thereby displaying the corresponding digit.

[0011] The beneficial effects achieved by the present invention are as follows: the present invention uses intelligent nanomaterials and non-contact adsorption display technology, utilizes magnetic fluid as a new material for clock digital display, and magnets adsorb magnetic fluid to realize the fluidity display of clock digital. With an original bidirectional self-deflecting magnet fixing structure and an integrated time reading and signal processing control scheme, an innovative breakthrough is achieved in the field of clocks. At the same time, it also has educational and popular science value, can stimulate people's interest in scientific principles, especially the understanding of magnetism and nanotechnology, and provides a vivid teaching tool for educational and popular science activities.
