Description

(54) DRIVE

one

The invention relates to the field of information technology and is intended for use as actuators of indicator devices, including indicators, which are information cells of mosaic boards.

Indicators are known in which the actuator is a cylinder with stirring inside the piston. Depending on the position of the piston in the cylinder, an informational sign appears on the face of a partial cylinder or disappears when the piston goes deep into cylinder ij.

A number of indicators can form an information mosaic panel, and the information can be passive, using external lighting, or active, in the case when there is a & M cell in the piston face.

Pneumatics or hydraulics are used to drive the piston.

Closest to the present invention, there is an indicator drive comprising a pin moving in a cylinder, which has a light-colored part at the end, and in the pin itself there is a permanent magnet interacting with an annular electromagnet. Depending on the magnitude and polarity of the voltage applied to the ring magnet, the pin moves in the cylinder to the appropriate position, highlighting the information sign on the board or dimming it. The permanent magnet in this device is designed as a rod located along the cylinder axis. To ensure the stability of the position occupied by the rod, a plate made of soft iron consisting of open rings f2j is inserted between the plates of the electromagnet.

The disadvantage of such a Vl 101x drive is high energy costs, since at the time of changing the information signal (pulse) to the opposite, additional energy is needed to overcome the fixing force, which leads to additional energy costs and the use of more powerful KONOvfyTHpy devices, in addition insufficiently reliable and, for example, in the case of vibration, the rod may change its position. The purpose of the invention is to reduce energy costs. The goal is achieved by the fact that the drive containing an electromagnet mounted on a piston rod and a stand magnet installed in the housing contains an additional permanent magnet made with opposite orientation of the poles with respect to the main one, and the permanent magnets are mounted on the rod on both sides of the electromagnet. The drawing shows the actuator design, for example for an indicator. The drive consists of a piston 1 with a piston 2, to which the information is attached to the one cell 3. The piston together with the rod can move in the housing 4. A permanent magnet 5 and a magnet 6 are mounted on the rod, pressed into the piston and fastened with a nut 7. Permanent magnets They are located on both sides of electromagnet 8 and have an opposite pole orientation. The drive works as follows. When a voltage pulse is applied to the winding of the electromagnet 8, the coil field, interacting with permanent magnets 5 and 6, does the work of moving the rod 1. Assume that the permanent magnet 5 has a polarity 5 from the front of the indicator and N opposite side. Then the magnet 6 is installed so that it has the polarity N on the side facing the front of the indicator, and S on the opposite. If in an electromagnet 8 a current creates a field, the polarity of which S to the front of the indicator and N to the back side, then the permanent magnet 5 is attracted to the electromagnet 8, and the constant is respectively repelled by the electromagnet 8. The rod moves from the front of the indicator until the permanent magnet 5 sticks to the body of the electrolytic 1gun 8, and the pin 1 locks in this position (reading of information, indication is carried out due to the different modulus of the light flux from the screen and formed from Erste). When changing the direction of the current in the electromagnet 8, its polarity changes and then the electromagnet 5 pushes off, and 6 pulls the electromagnet 8. The rod 1 moves to the opposite side until the magnet 6 sticks to the body of the electromagnet 8 (no indication, merging with the background account of the same modulation of the incident light flux from the screen and the end of the slit 1). Under conditions of low ambient light when using a light source at the end of rod 1, the stem moves to the screen, being fixed with the help of magnet 6 and electromagnet 8, information is acquired by modulating the light flux with a light source, for example, incandescent bulbs. The advantage of the proposed drive is that it creates an information cell that allows you to fill the information field as much as possible and create a high-resolution image, while the information is reproduced quite simply, reliably and with low energy costs. The proposed drive | It can be used in information display devices operated at different levels of ambient light (combined indicators), and also where video storage is needed at which energy is not expended, for example, in time devices.
