Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1, a magnetic turnover display based on a PCB coil, which comprises a PCB board 1, wherein a display area 6 is arranged on one side surface of the PCB board 1, the display area 6 is composed of four rectangular frames, a support 2 is fixedly connected to the opposite corners of each rectangular frame, the support 2 is used for supporting a turning plate 4, wherein a turning plate 4 rotatably connected with the support 2 is arranged in each rectangular frame area, the rectangular frame area is divided into two triangles, and the turning plate 4 is turned in the two triangles in a reciprocating manner to realize the purpose of changing the display. An iron core 3 used for supporting and connecting the turning plate 4 is arranged in the rectangular square frame area, and a PCB coil 5 which can be electrified to generate magnetic force is embedded on the surface of the PCB plate 1 by taking the iron core 3 as the center.

As shown in fig. 4, the turning plate 4 includes a triangular thin plate 401, pins 402 are disposed at bottom corners of two ends of the triangular thin plate 401, and a magnet 403 is embedded in a center of the triangular thin plate 401. The triangular sheet 401 has a magnet 403 in the middle, and the polarity of one surface of the magnet 403 is N and the polarity of the other surface is S. The triangular sheet 401 in a stationary state is attracted to one end of the iron core 3 by the magnet 403. The part of the dot matrix magnetic flip display, the display area 6, is made up of an array of triangular sheets 401 of black and light color on both sides, respectively, lined with a black background.

As shown in fig. 5, the support 2 includes a base 201, a threaded hole 202 is formed in a top surface of the base 201, grooves 205 are formed in four corresponding sides of the base 201, a cover plate 203 is disposed on a top of the base 201, and a screw 204 in threaded connection with the threaded hole 202 is fixedly connected to a bottom of the cover plate 203.

As shown in fig. 2-3, the pins 402 at two corners of the triangular sheet 401 are inserted into the inner side of the groove 205 with a certain gap and can be turned over freely. The magnet 403 is pushed by magnetic force generated by energizing the PCB coil 5. The magnets are realized to flip the triangular sheets 401. When the power is on, the triangular sheet 401 is turned to the other side; the flipped triangular sheet 401 will remain in the current position with the magnet 403 attracted to the core 3 without the PCB coil 5 being energized.

The triangular lamellae 401 are attached to a shaft with a small magnet. A PCB coil 5 is printed on the surface of the PCB 1 corresponding to the overturning and stopping position of the magnet. By applying a current to the PCB coil 5 with the appropriate polarity, the magnets 403 on the shaft will match the magnetic field generated, causing the triangular lamellae 401 to rotate. Two independent PCB coils 5 mounted at both ends or both sides within the rectangular area are used as the driving flip.

The basic purpose of the dot matrix magnetic flip display is to reduce the number of wires and electronics required to drive the PCB coil 5. The PCB coil 5 is located at the intersection of the two power supply connections, and a single horizontal or vertical power supply line provides only half of the required magnetic force (the electric flux is proportional to the current, which in turn is proportional to the voltage), and the two power supply lines can provide enough current to flip the triangular sheet. The triangular thin slices (pixel points) corresponding to the PCB coil 5 with insufficient power supply and the triangular thin slices on the power supply lines which are not electrified are not turned over.

In general, the driving scheme operates from top to bottom by sequentially supplying power to the required vertical lines while supplying power to each horizontal line, so as to complete the setting of the pixels in the row. The entire display content setting process takes several seconds.
