1 to 3 are an assembled perspective view, an exploded perspective view and an assembled cross-sectional view of a low power segment according to a first embodiment of the present invention, and FIG. 4 is a view for explaining the operation relationship of the first embodiment.

1 to 3, a low-power segment according to a first embodiment of the present invention includes a main body 10, a permanent magnet 20, a magnetic body 30, and a coil 40, 5, 6, and 7) for receiving and protecting the permanent magnet 20, the magnetic body 30, and the coil 40 on the inner side.

In the case of the present embodiment, the low power segments according to the present invention are combined with each other, and power is supplied to each of the combined segments to represent numbers, characters, etc. Hereinafter, a 7-segment indicator Will be described in detail as an embodiment.

The main body 10 is composed of a base plate 10 having a generally rectangular shape and a support base 12 protruding upward from both ends of the base plate 10. The support base 12 is provided with a permanent magnet 20 And a groove 12a into which the shaft 21 is inserted.

In this embodiment, the main body 10 supports the permanent magnet 20 by supporting it.

The support base 12 may be integrally formed or integrally assembled via fastening means (e.g., screws, adhesives, etc.) when the body 10 is manufactured.

The permanent magnet 20 has a rectangular shape as a whole, a shaft 21 is formed at both ends thereof, and a half of the permanent magnet 20 is an S pole in the longitudinal direction and the other half has a N pole (refer to FIG. 1) Is rotatably provided in the groove 12a of the support base 12 via the shaft 21 and is rotated by the magnetic body 30 and the coil 40. [

That is, the permanent magnets 20 are arranged on both sides of the upper surface (back surface) and the lower surface (opposite surface) of the permanent magnet 20 so as to be clearly identified by the user when rotated by the magnetic body 30 and the coil 40, The identification means 22 may be any one of a symbol (square, triangle, etc.), a color, a light emitting material, or a combination of at least two or more thereof.

In the present embodiment, a color (for example, a top surface (back surface) -white surface and a bottom surface (back surface) -black color) are applied so that the top surface (back surface) The external background color of the case 40 (see FIG. 8D) is set to be the same as any one of the two-sided color of the permanent magnet 20 (for example, top surface (back surface) - white surface and bottom surface If we unify it, the discrimination power can be further improved.

On the other hand, the upper surface and the lower surface of the permanent magnet 20 can be sufficiently divided into colors only in a bright place, but it is difficult to distinguish them from each other in a dark place, It is preferable to form (coat) the same and dissolve it.

The magnetic body 30 and the coil 40 are disposed on both sides of the permanent magnet 20 and change polarity by a current in a forward direction or a reverse direction applied to the magnetic body 30. The magnetic body 30 and the coil 40 have a function of reversing the upper and lower surfaces of the permanent magnet 20 .

3, one end of the magnetic body 30 is inserted into the main body 10 and the other end of the magnetic body 30 is protruded upward. The magnetic body 30 is disposed on the upper surface of the main body 10, (For example, a screw, an adhesive, or the like).

3, the coil 40 is wound around the magnetic body 30 and has a function of changing the polarity of the magnetic body 30 (refer to FIG. 4) by receiving a current in a forward direction or a reverse direction .

Meanwhile, in the present embodiment, the present invention is characterized in that power consumption is extremely small as compared with the conventional technology while performing the same function as that of the prior art, and the life span is long, so that it can be used semi-permanently.

4 (a), when there is no initial current supply, the permanent magnet 20 and the magnetic body 30 have polarity (NSNS) in which an attractive force acts between them The permanent magnet 20 is maintained in a stable state by the magnetic force.

When the permanent magnet 20 is rotated to represent numbers, letters, etc., when a current is supplied to the coil 40 of the magnetic body 30, the magnetic body 30 is magnetized and polarized, 4 (b) and 4 (c), a polarity (SSNN) in which a repulsive force acts between the permanent magnet 20 and the magnetic body 30 is applied, The permanent magnet 20 is naturally turned by 180 degrees so that the identification means 22 faces upward and if a plurality of the identification means 22 are provided, a specific number or letter is displayed.

Particularly, when the current supply is interrupted while a specific number or letter is completed by a plurality of identification means 22, a polarity (SNSN) in which an attractive force acts again between the permanent magnet 20 and the magnetic body 30 So that the state shown in FIG. 4 (d) can be maintained without supplying a separate current.

Therefore, according to the present embodiment, only when the permanent magnet 20, the magnetic body 30, and the coil 40 are used to represent numbers, characters, and the like, current is supplied, Since it does not require a current supply, it is very useful because it is possible to reduce the inconvenience and unnecessary power consumption that the current must be constantly supplied in order to maintain the number expressed in the conventional manner.

The case 60 (see Figs. 5 to 7) functions to receive and protect the main body 10, the permanent magnet 20, the magnetic body 30, and the coil 40, respectively.

Particularly, the upper surface of the case 60 is integrally formed with the exposed portion 61, which exposes the surface of the permanent magnet 20, wherein the exposed portion 61 is a hole.

FIGS. 5 to 7 are an assembled perspective view and an exploded perspective view of a low power segment according to a second embodiment of the present invention, and FIGS. 8A to 8D are views for explaining the operation relationship of the second embodiment.

In the case of the first embodiment, since the end of the magnetic body 30 is embedded in the main body 10, or the magnetic body 30 is wound around the periphery of the magnetic body 30 through the fastening means, There is a problem in that it is difficult to replace all unnecessary parts when damaged.

In this embodiment, the PCB 50 having the body 10, the magnetic body 30, and the coil 53 formed on the surface thereof can be disassembled and assembled to solve the above problems.

For reference, the low power segment according to the second embodiment of the present invention is substantially the same as the first embodiment described above, but there is a difference in the structure of some parts.

Also, for convenience of explanation, the second embodiment is applied to the 7-segment indicator, and this technique is not limited to the 7-segment indicator.

6 and 7, the main body 10 includes a base plate 11 which is generally plate-shaped and a plurality of supports 12 protruding upward from the upper surface edge of the base plate 11 And a groove 12a is integrally formed on the upper end of the opposing surface of the support base 12 facing each other. In this embodiment, the base plate 12 is coupled to the first coupling hole 51 of the PCB substrate 50, (20).

The permanent magnets 20 are disposed between the supports 12 and the shaft 21 of the permanent magnet 20 is rotatably inserted into the grooves 12a of the support 12.

The permanent magnet 20 has a rectangular shape as a whole, a shaft 21 is formed at both ends thereof, a magnet having an S pole in the longitudinal direction and a N pole in the other half in the longitudinal direction with respect to the shaft 21 Shaped in the main body 10 so as to be rotatably inserted into the grooves 12a of the supporter 12 and connected to the coils 53 of the magnetic body 30 and the PCB substrate 50 To represent the numbers 0 through 9 through the case 60. [0064]

That is, when the permanent magnet 20 is rotated and turned by the coil 53 of the magnetic body 30 and the PCB 50, the permanent magnet 20 is rotated in two directions, that is, The identification means 22 may be a combination of any one of a symbol, a color, and a light emitting material, or a combination of at least two or more thereof.

In this embodiment, a color (for example, upper surface (back surface) -white surface and lower surface (other surface) -black color) are applied so that the upper surface (back surface) At this time, if the external background color of the case 60 is unified in the same manner as any one of the two sides of the permanent magnet 20 (for example, top side (back side) - white side and bottom side (black side) Can be improved.

The upper surface and the lower surface of the permanent magnet 20 can be sufficiently divided into colors only in a bright place. However, since it is difficult to distinguish between the upper surface and the lower surface of the permanent magnet 20, It is desirable to form (apply) the substance and dissolve it.

The magnetic body 30 and the PCB substrate 50 are disposed between the main body 10 and the permanent magnets 20 to receive the current and rotate the permanent magnets 20 individually.

The magnetic bodies 30 are disposed on both sides of the respective permanent magnets 20 and are coupled to the second coupling holes 52 of the PCB 50 in this embodiment.

The PCB substrate 50 is provided with first and second coupling holes 51 and 52 and a coil 53 and a terminal 54. In this embodiment, And functions to change the polarity of the magnetic body 30 sandwiched between the engaging holes 52 via the coil 53. [

The first and second coupling holes 51 and 52 are holes formed in the PCB substrate 50 and the coil 53 is formed on the surface of the PCB substrate 50 so as to surround the second coupling holes 52 And the terminals 54 are formed at both ends of the PCB substrate 50 to receive a current.

Particularly, since the coil 53 is formed on the surface of the PCB substrate 50, it is not necessary to wind the coil 53 on the magnetic body 30 as in the first embodiment, There is an advantage that it can be manufactured more compactly.

Meanwhile, in the present embodiment, the present invention is characterized in that power consumption is extremely small as compared with the prior art while performing the same function as that of the prior art, but also semi-permanently usable.

As shown in FIG. 8A, since the permanent magnet 20 and the magnetic body 30 have polarity (NSNS) in which an attractive force acts between the permanent magnet 20 and the magnetic body 30, (20) is kept in a stable state by the magnetic force.

When a current is supplied to the coil 53 through the terminal 54 of the PCB 50 to rotate the permanent magnet 20 to represent a number, a magnetic body (not shown) 8C, the permanent magnet 20 and the magnetic body 30 have a polarity (SSNN) in which a repulsive force acts on each other as shown in FIG. 8C, As shown in the figure, the permanent magnets 20 are naturally rotated by 180 degrees, so that the permanent magnets 20 are rotated to represent the number 3, as shown in FIG. 8D.

In particular, as shown in FIG. 8C, when the current supply is interrupted, the permanent magnet 20 and the magnetic body 30 have a polarity (SNSN) in which an attractive force acts between the permanent magnet 20 and the magnetic body 30 again. It is possible to maintain the state shown in Fig.

Therefore, according to the present embodiment, when only the number (or character) is to be changed by using the permanent magnet 20, the magnetic body 30, and the coil 53 of the PCB substrate 50, Since it does not require a current supply to maintain the number (or character), it is very useful because it can reduce the inconvenience and unnecessary power consumption that must be constantly supplied to maintain the number (or letter) represented in the prior art.

In addition, since the main body 10, the permanent magnet 20, the magnetic body 30, and the PCB substrate 50 are structured to be mutually disassembled and assembled, only the corresponding parts can be replaced at the time of damage, There is an advantage.

The case 60 functions to receive and protect the main body 10, the permanent magnet 20, the magnetic body 30, and the PCB substrate 50, respectively.

Hereinafter, the operation of the present invention will be described.

8A to 8D are diagrams for explaining the operation relationship of the second embodiment.

8A, since the permanent magnet 20 and the magnetic body 30 have polarity (NSNS) in which an attractive force acts between the permanent magnet 20 and the magnetic body 30 without supplying power at the beginning, the permanent magnet 20 is in a stable state .

8B, when the permanent magnet 20 is rotated to represent a number, if a current is supplied to the coil 53 through the terminal 54 of the PCB 50, the second coupling hole 52, The permanent magnet 20 and the magnetic body 30 have a polarity (SSNN) in which a repulsive force acts on the permanent magnet 20 and the magnetic body 30, respectively.

Referring to FIG. 8C, the permanent magnet 20 is naturally rotated 180 degrees by a repulsive force between the permanent magnet 20 and the magnetic body 30.

Referring to FIG. 8D, the permanent magnets 20 are respectively rotated to represent the number 3 by the above-described operation.

In the case where the rotated permanent magnet 20 is to be turned over again, if the reverse current is applied to the coil 53 through the terminal 54 of the PCB 50, the polarity of the magnetic body 30 changes The permanent magnet 20 is rotated and inverted.

According to the present embodiment, in order to supply the current only when the number is to be changed by using the permanent magnet 20, the magnetic body 30 and the coil 53 of the PCB substrate 50, Since it does not require a supply, it is very useful because it can reduce the inconvenience and unnecessary power consumption that the current must be constantly supplied to maintain the number expressed in the conventional manner.

According to the present embodiment, since the identification means 22 formed on the upper surface or the lower surface of the permanent magnet 20 is formed (applied) with a luminous (luminous) material, it can be easily distinguished even in a dark place, There is an advantage.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the appended claims.
