Description

Technical Field

[0001] This utility model relates to a denial device, and more specifically to a shoulder-mounted laser denial device for unmanned aerial vehicles. Background Technology

[0002] The widespread use of drones has transformed traditional tasks such as reconnaissance, patrolling, and target strikes into unmanned or remotely controlled operations. Accompanying this is the research and development and application of various drone countermeasure technologies and related equipment. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a short-range, shoulder-mounted unmanned aerial vehicle (UAV) denial device.

[0004] This utility model provides a shoulder-mounted UAV denial device. The denial device includes a laser emitting unit containing a high peak power pulsed laser and an adjustable beam expander, an observation and aiming unit containing a rangefinder and an observation and aiming device, a control unit containing a denial device activation switch and a laser emitting unit trigger switch, a power supply, and a housing. The configuration of the laser emitting unit, observation and aiming unit, control unit, and power supply, as well as the structure of the housing and the placement of each unit, including the power supply, on the carrier satisfy the following: the denial device detects and locks onto the UAV target and measures the distance through the observation and aiming unit. Based on the distance measurement result, it manually or automatically adjusts the beam divergence angle of the laser beam output by the beam expander, and then or simultaneously triggers the laser emitting unit switch to emit a laser towards the UAV target. The adjustable beam expander includes: incremental adjustment of the beam divergence angle from a line-of-sight distance of 500 meters to 50 meters, or decremental adjustment of the beam divergence angle from a line-of-sight distance of 50 meters to 500 meters.

[0005] In this invention, the high peak power pulsed laser preferably has an output laser wavelength of 0.53 μm or 1.06 μm, a frequency of greater than 1 Hz to 40 Hz, a total single-pulse output laser energy of greater than or equal to 100 mJ to less than or equal to 600 mJ, and a frequency-doubled green light energy of 100 mJ to less than or equal to 300 mJ; more preferably, the high peak power pulsed laser has an output laser frequency of 5 Hz to 20 Hz, a total single-pulse output laser energy of greater than or equal to 100 mJ to less than or equal to 400 mJ, and a frequency-doubled green light energy of 100 mJ to less than or equal to 200 mJ.

[0006] When the high peak power pulsed laser is preferably configured with an output laser wavelength of 0.53 μm or 1.06 μm, a frequency of greater than 1 Hz to 40 Hz, a total single-pulse output laser energy of greater than or equal to 100 mJ to less than or equal to 400 mJ, and a frequency-doubled green light energy of 100 mJ to less than or equal to 200 mJ; and further preferably configured with an output laser frequency of 5 Hz to 20 Hz, a total single-pulse output laser energy of greater than or equal to 100 mJ to less than or equal to 400 mJ, and a frequency-doubled green light energy of 100 mJ to less than or equal to 200 mJ, the adjustable beam expander in the denier includes a beam divergence angle of 0.4 mrad to 0.5 mrad at a viewing distance of 500 meters, and a beam divergence angle of 2 mrad within a viewing distance of 100 meters (e.g., 5 to 100 meters).

[0007] In this invention, the laser is existing technology and can be designed and manufactured using existing techniques, or it can be commercially available. For example, in one specific embodiment, the laser used in this invention is an electro-optically Q-switched semiconductor laser-pumped YAG solid-state laser manufactured using existing technology.

[0008] In this invention, the functional components and power supply involved, such as the adjustable beam expander, the observation and aiming unit, and the control unit, are existing technologies. They will not be described in detail here.

[0009] In this invention, the sight is preferably a targeting telescope or a television infrared sight.

[0010] In this invention, the main function of the housing is to install and support components including a laser, beam expander, sight, control unit, and their assemblies. The housing is configured such that the laser, beam expander, sight, control unit, and other related components are either built into the housing or mounted externally. To ensure the use, carrying, and storage of the denial device, this invention does not limit the structural composition of the housing. Taking a television infrared sight including a television infrared camera and a display as an example, the configuration involves the television infrared sight being installed and supported on the housing to satisfy the following: the center of the crosshairs on the aiming telescope or the television infrared sight's display screen is the imaging center of the camera; the laser output laser axis is adjusted to be parallel to the camera's optical axis and coincide with the imaging crosshair center, ensuring that the crosshair center presses against the target, and the laser beam covers the target.

[0011] Furthermore, while ensuring sufficient installation and support, the housing should also consider factors such as laser heat dissipation, compactness, and aesthetics. For example, the housing can be designed as an open mesh, either entirely or partially, to meet requirements such as laser heat dissipation.

[0012] Provided that the power supply requirements are sufficiently met, this invention does not impose any restrictions on the power source. Generally, to ensure the shoulder-carryability of the denial device, the power source is selected from batteries, rechargeable batteries, etc. The power source can be built into the denial device housing or placed outside the housing, such as being designed as a pluggable independent power source. In addition, the laser emitting and observation units can each be powered independently or powered by a single power source. When powered independently, there are no restrictions on their independent configuration. Each power source can be built into the denial device housing or placed outside the housing, including individual or both power sources designed as pluggable independent power sources.

[0013] According to this utility model, the deterrent device includes a shoulder rest. The shoulder rest can have different forms for the purpose of facilitating shoulder carrying and stable aiming. This utility model does not limit its application in this regard.

[0014] In this invention, the denial device may optionally include a laser emission function lock / unlock module.

[0015] To ensure the security of the denial device, various methods can be used to lock and unlock the laser emission (trigger) function. For example, the function lock / unlock module can be selected from mechanical locks, electronic locks (e.g., electronic combination locks), or biometric locks (e.g., fingerprint locks).

[0016] In this invention, the denial device may optionally include the denial device status detection module.

[0017] The denial-of-service status detection module is existing technology. It includes, for example, installing a photoelectric sensor inside the laser to detect the laser's light emission status and send the data to the laser emission control unit, and then to a display screen for display.

[0018] In the above discussion of the denial device, other components commonly used with the denial device, or specific details of the unit or system, which are well known to those skilled in the art, have been omitted. For example, the denial device may have a built-in satellite positioning chip to read or display its coordinates; it may have a built-in fan to meet the heat dissipation needs of the laser, etc. Those skilled in the art can easily select and configure these as needed, and they will not be elaborated upon here.

[0019] This invention is based on the principle that after a laser beam enters a camera optical system, it converges to the focal plane of the optical system, and the high energy density and high peak density of the laser beam instantly damage the internal structure of the sensor pixels. The denial device is particularly suitable for denying unmanned aerial vehicles (UAVs) in short-range airspace, such as within a line-of-sight range of 500 to 50 meters. Attached Figure Description

Detailed Implementation

[0026] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0027] In this utility model, the unmanned aerial vehicle (UAV) refers to a type of aircraft with an empty weight of ≤25 kg; the short range refers to an airspace range with a visual distance of less than 500 meters.

[0028] In this utility model, the configuration refers to the basic composition of components and functional units such as the laser emitting unit, the observation and aiming unit, the control unit, the power supply, and the housing included in this utility model.

[0029] The setup includes design and / or arrangement. For example, to improve the overall compactness of the denial device, the design of the housing structure and the arrangement of the laser emitting unit, observation and aiming unit, control unit and power supply on the housing, etc.

[0030] In a preferred embodiment, this invention provides a denier employing a manually adjustable three-position beam expander. The composition, operation, and output denial laser beam pattern of the laser emitting unit and the observation unit in this denier are as follows: Figure 1 As shown.

[0031] according to Figure 1 The laser emitting unit 21 includes a laser and a beam expander, and the observation and aiming unit 11 includes a rangefinder and an observer. The beam spread angle settings of the laser beam output from the beam expander are as follows: first setting: 0.4 mrad to 0.5 mrad at a line-of-sight distance of 500 meters; second setting: 0.67 mrad to 0.83 mrad at a line-of-sight distance of 300 meters; third setting: 2 mrad at a line-of-sight distance of 100 meters.

[0032] During use, the operator detects the UAV target and measures the distance through the observation and aiming unit 11, reads the distance measurement result 41, adjusts the beam expander to the first position, and triggers the laser to emit laser 3 based on the observation and aiming result 5. The laser 3 is output as a rejection laser beam 6 through the beam expander.

[0033] Figure 1 The image shows the laser beam output from the three adjustable beam expanders at the following locations: spot 9 at 500 meters, spot 8 at 300 meters, and spot 7 at 100 meters, corresponding to laser beam rejection I, laser beam rejection II, and laser beam rejection III, respectively.

[0034] In another preferred embodiment, the present invention provides an automatically adjustable beam expander. The configuration, operation, and output deny laser beam pattern of the laser emitting unit and the observation unit in this deny device are as follows: Figure 2 As shown.

[0035] according to Figure 2 The laser emitting unit 22 includes a laser and a beam expander, and the observation and aiming unit 12 includes a rangefinder and an observer. The beam expander is an automatically adjustable type. In use, the observation and aiming unit 12 detects and measures the distance to the UAV target. The beam expander automatically reads the ranging result 42 and adjusts the beam divergence angle of the laser beam output from 0.4mrad to 0.5mrad at a line-of-sight distance of 500 meters to 2mrad at a line-of-sight distance of 100 meters. Simultaneously, the operator triggers the laser to emit laser 3 based on the observation and aiming result 5. This laser 3, output through the beam expander, becomes a denial laser beam, achieving denial of the target UAV 6.

[0036] Figure 2 The image shows the laser beam output from the automatically adjustable beam expander at spot 9 at 500 meters and spot 7 at 100 meters, corresponding to laser beam rejection III and laser beam rejection IV, respectively.

However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple changes can be made to the technical solution of the present invention, and these simple changes all fall within the protection scope of the present invention.
