[0002] Unmanned vehicles, including drones, are devices that can be controlled from the ground with a remote control or controller. They were developed in the 1960s as military aircraft for reconnaissance of the opposing camps during the Cold War between the United States and the Soviet Union (Russia). Until the 1990s, unmanned vehicles were only used for military purposes in limited areas, such as in the Gulf War in the Middle East and the Kosovo crisis. Recently, with the development of wireless communication technology, unmanned vehicles are being operated based on a wide flight area.

[0023] The present invention relates to a high-voltage self-destruct system for an unmanned vehicle, and is structured so that when the cover of the control unit is opened without permission, the switch unit is turned ON, high-voltage power is supplied to the main board, and high-voltage damage is inflicted on the main board, so that even if the unmanned vehicle used for military operations is captured by the enemy or crashes into enemy territory, flight information including the takeoff position, flight path, and return position recorded on the main board can be deleted, and the main configuration includes a fuselage (100), a control unit (200), a switch unit (300), and a high-voltage self-destruct module (400).

[0024] The fuselage (100) according to the present invention includes a battery (110), a main board (120) on which a communication module and a flight controller module are mounted, and a motor (140) connected to the main board (120) to drive a propeller (130).

[0025] The above body (100) can be configured as a drone of various forms that flies with power from a battery (110).

[0026] In addition, the control unit (200) according to the present invention is formed in the body (100), accommodates a battery (110) and a main board (12), and is provided to be opened and closed by a cover (210).

[0027] The above control box (200) is provided to house and protect the main control components of the unmanned vehicle, including the main board (12), while being closed by a cover (210).

[0028] And, it is provided so that the settings can be changed or flight information can be extracted by connecting to the main board (12) only when the cover (210) is opened.

[0029] In addition, the switch unit (300) according to the present invention is installed in the control unit (200) and is provided to detect the opening operation of the cover (210).

[0030] Here, the switch unit (300) can be applied in various forms of switches and sensors that can detect the opening operation of the cover (210). For specific examples thereof, refer to the detailed description given below.

[0031] In addition, the high-voltage self-destruct module (400) according to the present invention is provided so that when the opening operation of the cover (210) is detected by the switch unit (300), high-voltage power is supplied to the main board (120), thereby causing high-voltage damage to the main board (120).

[0032] In FIGS. 3 and 4, the high-voltage self-destruct module (400) comprises: a high-voltage power supply unit (410) that provides high voltage by boosting the power of the battery (110) or provides high voltage power using a separate high-voltage battery, and whose high-voltage power supply is controlled ON / OFF by a switch unit (300); a pair of jumper pins (420) that are connected to a power line (422) that connects the high-voltage power supply unit (410) and the main board (120) to keep the power line (422) in a disconnected state; a jumper plug (430) that is detachably installed on a pair of jumper pins (420) to activate the power line (422) in a energized state; a jumper case (440) that is provided to surround the jumper pin (420) and the jumper plug (430), and has an opening (442) formed on one side to allow the jumper plug (430) to enter and exit; It includes a cap (450) installed to close the opening (442) of the jumper case (440).

[0033] And, as shown in Fig. 4 (a), after the jumper plug (430) is separated to set the power line (422) to a disconnected state, and the cover (210) is assembled to the control unit (200), the switch unit (300) is turned OFF and the high voltage power supply to the main board (120) is cut off, and as shown in Fig. 4 (b), the jumper plug (430) is connected to the jumper pin (420) to switch the power line (422) to a energized state.

[0034] Thereafter, when the cover (210) of the control unit (200) is opened without permission, the switch unit (300) is switched to the ON state, and high voltage power is supplied from the high voltage power supply unit (410) to the main board (120), so that high voltage damage is applied to the main board (120). Therefore, even if an unmanned vehicle used in military operations is captured by the enemy or crashes into enemy territory, there is an advantage that the enemy cannot obtain flight information including the takeoff position, flight path, and return position recorded in the main board (120).

[0035] In Fig. 5, the switch unit (300) includes a sensing piece (310) that is pressed by a cover (210) and a switch body (320) that detects movement of the sensing piece (310) and switches the contact point.

[0036] And, when the cover (210) is closed, the sensing piece (310) is pressurized so that the switch part (300) is maintained in the OFF state, and when the cover (210) is opened, the switch part (300) is switched to the ON state.

[0037] In FIGS. 6 and 7, the switch unit (300) comprises a cylinder body (330) installed in a control box (200), a cylinder room (332) formed inside, and a pinhole (334) formed on the outside to communicate with the inside of the cylinder room (332), a fixed electrode (340) installed at one end inside the cylinder room (332) and provided to supply high-voltage power to the main board (120) by an output cable (342), a moving electrode (350) accommodated inside the cylinder room (332) and having an elongation force applied to the fixed electrode (340) by an elastic body, a stop home (352) formed on the outer surface, and an input cable (354) connected to supply high-voltage power from a high-voltage self-destruct module (400), and one end connected to the cover (210) and the other end penetrating the pinhole (334) It includes a safety pin (360) that is interlocked with the stop home (352) and restrains the moving electrode (350) to be positioned and separated from the fixed electrode (340).

[0038] And, when the cover (210) is closed, the safety pin (360) engages with the stop home (352) to fix the position of the moving electrode (350) in a state separated from the fixed electrode (340) and maintain the switch unit (300) in the OFF state, and when the cover (210) is opened and the safety pin (360) is separated, the moving electrode (350) is extended and moved to contact the fixed electrode (340) and the switch unit (300) is turned in the ON state, so that high voltage is supplied to the main board (120), and high voltage damage is applied to the main board (120).

[0039] At this time, since the pinhole (334) is provided to be closed by the outer surface of the moving electrode (350) after the safety pin (360) is separated, there is an advantage in that the position of the moving electrode (350) cannot be manipulated by inserting a sharp tool into the pinhole (334) to forcibly turn OFF the switch unit (300).

[0040] Additionally, the safety pin (360) is provided to be connected to the cover (210) by a one-way joint (370).

[0041] In the enlarged view of Fig. 6, the one-way joint part (370) includes a wedge-shaped elastic hook (372) formed on a safety pin (360), and a hook groove (374) formed on a cover (210) and having a hooking protrusion (373) formed at the entrance so that the wedge-shaped elastic hook (372) is hooked and connected while being inserted.

[0042] The above safety pin (360) is inserted into the pinhole (334) and engages with the stop groove (352) so that the moving electrode (350) is kept in a state of being spaced apart from the fixed electrode (340), and when the cover (210) is closed on the control unit (200), the wedge-shaped elastic hook (372) and the hook groove (374) are engaged so that the safety pin (360) is connected to the cover (210), and the safety pin (360) is separated when the cover (210) is opened.

[0043] That is, until the cover (210) is assembled, the switch unit (300) is firmly maintained in the OFF state by the safety pin (360), and at the same time as assembling the cover (210), the safety pin (360) is fastened to the cover (210) by the one-way joint (370), so that when an outsider forcibly opens the cover (210), it is activated in a state where high voltage damage is applied to the main board (120).

[0044] In Fig. 8, the above-mentioned fluid electrode (350) is formed by dividing into front and rear parts (350A) (350B), and is connected to each other by an inner shaft rod (354) and an inner shaft hole (355) so that the extension length is adjusted, and the inner shaft rod (354) is provided so that an extension transfer force is applied by an elastic body accommodated in the inner shaft hole (355).

[0045] At this time, a stop home (352) is provided in the tip part (350A), and an input cable (354) is connected to the rear part (350B).

[0046] And, when the safety pin (360) is separated when the cover (210) is opened, the moving electrode (350) is extended and moved to contact the fixed electrode (340), and the switch unit (300) is turned ON so that high voltage is supplied to the main board (120), thereby causing high voltage damage to the main board (120).

[0047] That is, after the safety pin (360) is separated, the pinhole (334) is closed by the rear part (350B), and even if the rear part (350B) exposed through the pinhole (334) is forcibly moved in the opposite direction of the fixed electrode (340), the front part (350A) is provided to be extended and transported by the inner shaft rod (354) and the inner shaft hole (355) so that the contact state between the fixed electrode (340) is maintained, so that there is an advantage in that the position of the moving electrode rod (350) cannot be manipulated by inserting a sharp tool into the pinhole (334) to forcibly turn OFF the switch unit (300).
