Description

Target driving device {Driving apparatus for shooting target}

The present invention relates to a target driving method and apparatus, and more particularly, to a target driving method and apparatus for applying a worm gear connection method to transmit the rotational force of the drive motor to the target to rotate.

In general, during a survival game and military training, a target to be fired is installed, and such a target is fixedly installed at a certain position or is normally hidden. In some cases, the target may be protruded by the driving of the motor when the sensing operation and the predetermined time elapse.

1 is a block diagram showing a conventional target driving device.

As described above, in the conventional target driving device, a pair of supports 11 are extended at both lower ends of the target 10, and the pair of supports 11 are installed adjacent to both sides of the main body 12, and the main body ( 12) Inside the drive motor 13 is disposed in the transverse direction is installed on any one of the support 11 of the pair of support 11 to receive the rotational force of the drive motor 13 directly.

In the above configuration, when the operation signal is applied to the drive motor 13 from the detection signal of the external sensor, the rotational force is transmitted to any one support 11 connected to the rotating shaft together with the drive of the drive motor 13 (Down ), The target 10 rotates to the Up state, or vice versa, the target 10 in the Up state rotates to the Down state.

However, such a conventional target drive device has a problem that excessive load is generated on one support 11 receiving the rotational force since the rotational force of the motor is concentrated and concentrated on any one support 11, and the gear ratio does not coincide with the gear connection. As a result, there was a problem that the target 10 may malfunction or a strong operating shock may occur.

In addition, a play may be formed at the connection portion between the target 10 and the main body 12 during the operation of the target 10, which causes the target 10 to operate in a shaking or torsional state so that the target and the driving device may be operated. There was also a problem leading to breakage and thereby shortening the life.

Therefore, the present invention has been made to solve the above-mentioned problems of the prior art, the same load acts on a pair of supports supporting the target to prevent the overload that was acting only on one side of the support, and thus damage to the target It is an object of the present invention to provide a target drive device which can be prevented and extended in service life.

As a technical means for achieving the above object, the present invention seeks a technique for connecting a pair of supports to the shaft and control the shaft.

That is, the outer circumference of the shaft is to form a worm that is a helical gear, the motor is arranged to intersect the shaft, but the worm wheel is formed at the front end of the rotating shaft of the motor to provide a power transmission structure that meshes with the worm to achieve the object of the present invention. .

According to the target driving method and apparatus according to the present invention, the problem that the load is concentrated only on one side support during rotation of the target, and to prevent the occurrence of play on the connection portion between the target and the body during the operation, which In addition to preventing damage to the target and drive device, the service life thereof is extended.

1 is a block diagram showing a conventional target driving device,
2 is a perspective view of a target driving device according to an embodiment of the present invention,
3 is an enlarged perspective view illustrating main parts of a target driving device according to an exemplary embodiment of the present invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

2 is a perspective view of a target driving device according to an embodiment of the present invention.

As described above, the configuration of the present invention is largely divided into a target unit 100 and a driving device 200 for operating the target unit 100 up-down, and the target unit ( Worm gear connection is applied as a power transmission method for up-down.

In the target portion 100, the upper panel 110 corresponding to the target, a pair of supporters 120 extending from the lower end of both sides of the upper panel 110, and the pair of supporters 120 Rotation together with each other to rotate the outer periphery is configured to include a worm shaft 130, the worm is formed on the outer periphery, additionally installed on the upper panel 110 to determine whether the bullet hit or not by the impact Piezoelectric sensor 140 may be further included.

The drive device 200 includes a main body 210 corresponding to a case, a drive motor 220 disposed inside the main body 210, and a worm wheel 230 connected to a tip of a rotation shaft of the drive motor 220. And a control unit 240 for transmitting an operation control signal to the driving motor 220 and a communication unit 250 for receiving a remote control signal, wherein the main body 210 is formed by a plurality of fastening means 260. Since it is fixedly installed, it forms a stable fixed state even if it is installed on the moving object.

In the above configuration, the pair of supports 110 is installed adjacent to the side of the main body 210, the worm shaft 130 is connected to the main body 210 in the transverse direction, and both ends of the worm shaft 130 are supported ( 110 has an organic bonding configuration.

In addition, the driving motor 220 is formed in a direction in which the rotation axis intersects with respect to the worm shaft 130, the worm is formed in the outer peripheral edge of the center portion of the worm shaft 130 is a spiral gear, the drive motor 220 Since the worm wheel 230 is connected to the front end of the rotation shaft, a worm gear connecting method in which the worm shaft 130 and the worm wheel 230 mesh with each other is applied.

In the driving device 200 as described above, the driving motor 220 is to determine whether to drive from the operation control signal of the control unit 240, the control unit 240 is a communication unit for detecting the detection signal of the external sensor and the remote control signal of the manager. After receiving from the 250 to transmit it as an operation control signal of the driving motor 220.
