FIELD OF THE INVENTION The present invention relates to a signal display element suitable for passive battery display devices in a signal display element

- motherboard and

- the motherboard can be controlled by electromagnets with a coil parallel to the base of the motherboard facing the side of the sign display surface;

- Electromagnetic core cores parallel to the motherboard close to an acute angle with the pivot axes, and

- a tilting plate (s), which can be rotated between two end positions around the end plate (s), on the base plate, on the side of the sign display surface;

two sides of the tilting plate (s) having a surface having two different information, preferably a different color surface, and

- the entire surface of the motherboard is the same two information as the tilting plate (s), preferably the same two-color surface, while

- the surface of the motherboard carrying one of the information, preferably a light colored surface, is formed on portions that can be covered by one of the information carrying surfaces, preferably a light colored surface.

As is well known, numerous solutions are used to create pixel groups of passive, electromagnetically excited, color contrast signal display elements suitable for displaying information. Such a solution is described, for example, in HU 157 250, where tilting plates with a permanent magnetic part are mounted on the motherboard by means of electromagnetic excitation by a 180 ° pivot between two end positions. The tiles have two different color surfaces, and one of the colors is the same as the base color of the motherboard, while the color of the parts of the motherboard that can be covered by the tilting plate is the same as that of the tilting plate. The excitation electromagnet is a so-called "stationary iron" solution, ie the center line of the iron core and the excitation coil is perpendicular to the motherboard and the signal display surface.

The latter, due to the open magnetic circuit, was not very effective because of the reduction of the size of the pixels thus formed was the main goal for the first time, and it was easier to implement with the rolls. The U-shaped iron core electromagnet, coiled with a coil parallel to the signal display surface, was used to seal the magnetic circuit to a greater extent, which affected the extent of miniaturization. Such a solution is described, for example, in HU 173 858. Here, in one embodiment, the excitation coil engages an angle with the pivot plate axis, and thus one pole with a permanent magnet positioned at one end of the pivot plate, and the other pole with a permanent magnet on the other end of the pivot plate. The two permanent magnets in the tilting plate are magnetized perpendicular to the tilting plate sheet, but in opposite directions, so that only the portion of the magnetic circuit 35 over the tilting plates remains open. It is also known that the development of the material of the permanent magnets has made it possible to concentrate a small magnetic force at a small location, and thus the magnets in the tilting plate could be reduced by the distance from the pivot shaft, because as the force increases, the torque did not decrease by reducing the force of the force. Finally, permanent magnets were able to fit tightly to the pivot shaft and, where possible, extend to both sides of the pivot shaft. The magnets of the U-shaped "recessed" core magnet are attracted by the magnets in the tilting plate after the magnets at the two ends of the tilt shaft are magnetized perpendicularly to the surface of the tilting plate, and when the current is changed, the repulsive force at both poles is already shifted by a small lever. the tip plate to the other end position. In these cases, the portion of the U-shaped core core is parallel or very small at an angle with the pivot shaft.

However, this solution is extremely expensive due to the special magnets and is therefore not economical. In particular, it is not economical if it is used in large segment segment display devices, where the segment's tilt axis length and

EN 217 751 Β more axial displacement electromagnets shall be used in axially displacement due to the increased mass being tilted.

It is an object of the present invention to reduce or eliminate the above-mentioned drawbacks and to provide a signal display element in which the safe control can be economically solved by the use of several electromagnets shifted axially.

The invention is based on the recognition that, if the large axially displaced electromagnets in the direction of the pivot shaft are used, only the electromagnets at the two ends of the pivot shaft at the two ends of the pivot shaft are positioned below the pivot axis and all other poles are located away from the pivot axis. then, only two permanent magnets at two ends of the pivot shaft must be made of special material, made from other cheap magnets, and the benefits of the two solutions are summed up.

The essence of the invention is that

- at least two electromagnets displaced in the direction of the pivot shaft in the signal display element

- of the electromagnets, the poles of the electromagnet on the two ends of the pivot shaft at the two ends of the pivot shaft under the pivot shaft, perpendicular to the pivot axis, are preferably positioned at least tangentially such that

- one of the poles at the ends of the pivot shaft on one side of the end of the pivot shaft at one end position of the pivot plate,

- the other pole at the ends of the pivot shaft is on the other side of the end of the pivot shaft, in the other end position of the pivot plate, against the permanent magnet in the pivot plate;

- the other poles of the electromagnets are arranged further away from the pivot axis.

The invention will be described in more detail by means of the embodiments shown in the figures.

Fig. 1 is a schematic diagram of two electromagnetic signal display elements according to an embodiment of the present invention; Fig. 2 shows three electromagnetic signal display elements according to another embodiment of the present invention; an electromagnetic signal display element.

The base plate 1 shown in Figure 1 shows a longitudinal side of a tilting plate 3, which can be rotated about two end positions around the end shaft 2, on the side of the label display surface of the base plate. The motherboard 1 can be controlled by a coil 6 having a shaft 4 parallel to the motherboard and facing the side opposite to the side of the signal display surface, with the iron cores 5 parallel to the base plate 1 of the electromagnets 6 at an acute angle with the pivoting shafts 2.

The two sides of the tilting plate 3 have two surfaces with different information, preferably a different color surface. The total surface of the base plate 1 is the same information as the tilting plate 3, preferably the same two-color surface. The surface of the base plate 1 carrying one of the information, preferably a light colored surface, is formed on portions that can be covered by an information carrying surface of the tilting plate 3, preferably a light colored surface.

Figure 1 shows the two electromagnets 6 displaced in the direction of the pivot shaft 2, which are displaced perpendicular to one another by the pivot axis 2, such that the poles of the electromagnets 6 at the two ends of the pivot shaft 2 below the pivot axis 2 are displaced. , passing through the pivot axis 2, perpendicular to the plane of the display of the signal, symmetrically according to the example, but preferably this plane is at least tangentially disposed. If the poles are not symmetrical to the plane passing through the pivot axis 2 perpendicular to the sign display surface, one pole on one side of the end of the pivot shaft 2, one end position of the pivot plate 3, the other pole at the ends of the pivot shaft 2, on the other side of the end of the pivot shaft, the other pivot plate 3 in its end position against the permanent magnet 7 in the tilting plate 3. The other two adjacent poles of the electromagnets 6 are disposed further away from the pivot axis 2 and fall into a common line perpendicular to the pivot axis 2 according to the example. At one end position of the pivot plate 3, the pole of one of the electromagnets 6, while the other end position of the pivot plate 3, has a pole 6 in connection with the permanent magnet 7 in the pivot plate.

The adjacent poles of the electromagnets 6 need not necessarily fall into a common line perpendicular to the pivot axis 2, but the displacement axis 2 displacement relative to the pivot axis 2 of the permanent magnet 7 is therefore not economical.

If the tilt axis 2 of the tilting plate 3 is relatively large in relation to its size perpendicular to the pivot axis 2, the two electromagnets 6 shown in Figure 1 may be displaced in the direction of the pivot shaft 2 so that one or more electromagnets 6 may be disposed therebetween. In the embodiment of Figure 2, there are three electromagnets 6 displaced in the direction of the pivot shaft 2. The two poles of the central electromagnet 6 on both sides of the pivot shaft 2 are at the same distance from the pivot shaft 2 as the adjacent poles of the adjacent outer electromagnets 6, and fall into a straight line perpendicular to the pivot axis 2, as in the example.

In Figure 2, it can be seen that while the iron core 5 parallel to the base plate 1 of the two extreme electromagnets 6 is parallel to one another, the core 5 of the central electromagnet 1 parallel to the motherboard 1 has a different, higher acute angle with the pivot shaft 2. When two internal electromagnets 6 are disposed between the two external electromagnets 6, the two internal electromagnets 6 are parallel to one another.

Figures 1 and 2, as well as the number of electromagnets produced with the increased number of electromagnets 6 as described herein, only work if there is a bar3.

EN 217 751 két which two adjacent 6 electromagnets are excited in the opposite sense.

In Figure 3, the adjacent poles of the electromagnets 6 shown in Figure 1 are also displaced in the direction of the pivot shaft 2, however, the two ends 7 of the permanent magnet 7 in the pivot plate 3 that can be brought into contact with the electromagnet 6 are perpendicular to the tilting plate. but magnetized in the opposite sense. This solution is also suitable for designing more than three electromagnets, but in this case all electromagnets 6 are excited in parallel.
