Field digital display device of the present utility model mainly comprises: surface cover 1, main die holder 2, baffle plate 5, Electromagnetically turn over word 6, coil rack 7, magnetic bobbin core 8, coil clamp 9, main die holder (see figure 3) is one of core component in the whole magnetic flip displays device, seven fields 6 respectively sequentially, each field dead zone in " 8 " printed words as shown is enclosed within on each end axle 21, the end axle of two symmetries of same word end be positioned at same axially on, and the axial right alignment of having relatively high expectations, on the end axle of each group, be provided with a locating shaft 22, match, make the field 6 that assembles stationkeeping and difficult drop-off on main die holder with pilot hole 31 (Fig. 4) on the surface cover.Field 6 is cylindrical, and its two ends are slightly conical, and the two ends of field 6 have coaxial end axis hole 54 (Fig. 7), and they match with the end axle 21 of main die holder, comprise right alignment and position, hole, aperture adaptive.Field 6 fits on the end axle 21, and the restriction of being located retaining 55 can rotated along make 180 degree on two directions around end axle 21, field 6 is made up of two halfbodies vertically, the color of two halfbodies has obvious aberration, as Chinese red and black, when field is done a direction rotation, a halfbody is positioned on the front surface of main die holder, when field forwards other direction to, second half body is positioned at the front face location of main die holder, field 6 under the control in magnetic field, only do 180 degree around the diameter of axle to upset, and on main die holder, do not move axially.The centre position of field 6 fixedly installs a permanent magnet.
Fig. 7 represents the synoptic diagram of Electromagnetically turn over word, the center section of field is cylindrical, the slightly tapered contraction in two ends, end axis hole 54 matches with end axle 21 on the main die holder, a halfbody 52 of field, and another halfbody 51 makes with the ABS material of Chinese red and black respectively, settles magnet 53 in the middle dead zone of field, the direction that changes solenoid obtains different polarity to realize the 180 degree upsets of field around the end axle, and location retaining 55 can be made 180 degree alignment restrictions to the field upset.
Surface cover 1 (Fig. 4,5) be one by plastics, as the parts that the ABS material constitutes, the effect of these parts is positions of fixing main die holder axle head group, makes display only show the font of desiring display field simultaneously.Reflective for preventing, blasting treatment is done on the surface cover surface.
Baffle plate 5 (Fig. 6), the one end is the square plane, just in time be positioned at two space region positions up and down of the figure of eight, and the other end has four pins, they can rely on mutual elasticity to assign on the electromagnetism reverse control circuit plate 3 of display, baffle plate 5 can be made with commaterial with cover 1, and is reflective in order to prevent, also does corresponding blasting treatment on its surface.
The solenoid that causes display field to do the upset rotation in the display is by coil rack 7, and magnetic bobbin core 8 and coil clamp 9 are formed.Solenoid is placed on the electromagnetism reverse control circuit plate 3, its position just in time corresponds to display display field position, as for figure of eight display, have seven display fields 6, on control panel 3, face seven field locations seven solenoids are set, so that carrying out electromagnetism when control upset, make with the solenoid opposite position on the display field demonstrations of making 180 degree rotate.
To do a summary to the principle of the control solenoid polarity commonly used that adopted in the display described in the utility model below.
