Description

A drone for pointing lights Technical Field

[0001] This utility model relates to the field of drone lighting equipment technology, specifically to a drone for directional lighting. Background Technology

[0002] With the development of drone technology, drones have been rapidly applied in fields such as rescue, exploration, surveying, and air transport. Various expansion needs based on drone technology have increased rapidly, mainly for environmental detection and real-time image transmission. This requires drones to carry certain additional equipment within their load-bearing capacity.

[0003] In related technologies, rescue drones fly to observe areas of a fire that are not burned by flames. These areas are usually covered by thick smoke. Most drones can only guide people to evacuate through loudspeakers. However, the lighting equipment commonly used by drones can only illuminate the area near the drone itself. Although this does not affect the normal operation of the drone, it is very limited in guiding people in distress, making it difficult for them to quickly find an escape exit. To solve the above problems, a drone for directional lighting is proposed. Summary of the Invention

[0004] In view of this, the present invention provides a drone for directional lighting. The present invention activates the laser diode in the laser irradiation component through a laser power supply, and then forms a laser that can penetrate smoke through the laser tube to irradiate the focusing lens group, thereby irradiating the directional icon and illuminating the pattern of the directional icon on the ground to guide the person in distress, thereby improving the survival rate of the person in distress.

[0005] To solve the above-mentioned technical problems, this utility model provides a drone for directional lighting, including a quick-connect connector at the bottom of the rescue drone, an angle adjustment component fixedly installed at the bottom of the quick-connect connector, a connecting block rotatably installed at the bottom of the angle adjustment component, a connecting plate fixedly installed at the bottom of the connecting block, a rotating gimbal at the bottom of the connecting plate, a laser power supply on the bottom bearing surface of the rotating gimbal, a laser irradiation component installed on the downward tilted housing of the laser power supply, and a detachable directional icon installed at the light output end of the laser irradiation component.

[0006] The angle adjustment assembly includes a pair of arc-shaped bases for fixing and mounting the rotating shaft, thereby limiting the rotation of the rotating shaft. Each arc-shaped base is inverted and mounted on the bottom of the quick-connect connector. A rotating shaft is rotatably connected between the arc-shaped bases. The rotating shaft is used to mount a connecting block, so that the connecting block can rotate with the rotating shaft. A motor is connected to one end of the rotating shaft. A ratchet assembly can be set at the output end of the motor to improve the rotation accuracy of the rotating shaft. The motor is used to drive the rotating shaft to rotate. A rotating base is connected to the other end of the rotating shaft. The rotating base is used to fix the end of the rotating shaft and prevent the rotating shaft from detaching from the arc-shaped base.

[0007] A connecting block is fixedly installed on the surface of the rotating shaft. The connecting block is used to connect the rotating shaft to the connecting plate. When the connecting block rotates with the rotating shaft, the connecting plate and the components installed at its bottom can rotate synchronously. The bottom of the connecting block is connected to the connecting plate by bolts.

[0008] The laser irradiation assembly includes a heat dissipation housing connected to the laser power supply housing. The heat dissipation housing is used for heat dissipation of the entire laser irradiation assembly and can be made of copper. The heat dissipation housing also protects the components inside the laser irradiation assembly. A laser tube is set inside the heat dissipation housing. The laser tube is used to fix the reflectors at both ends of the resonant cavity. The laser tube is set as a resonant cavity. A laser diode is set at the end of the laser tube near the laser power supply. The laser diode is used to generate the initial laser light source, which is then used to irradiate the focusing lens group through the laser tube. A focusing lens group is set at the end of the laser tube away from the laser power supply. The lens in the focusing lens group is concentric with the laser tube. The focusing lens group is used to output the laser in the laser tube, so that the laser irradiates the pointing icon, and then illuminates the pattern of the pointing icon on the ground.

[0009] Multiple heat dissipation holes are provided through the front and rear sides of the upper end of the heat dissipation housing. The heat dissipation holes penetrate the heat dissipation housing and are used for heat dissipation of the laser diode. The heat dissipation holes are located in the upper part of the heat dissipation housing.

[0010] The bottom of the heat sink housing is equipped with an internal threaded cylinder, which is used to connect the external threaded tube to the heat sink housing. This allows the directional icon fixed inside the external threaded tube to connect with the laser irradiation component. The internal threaded cylinder is concentric with the lens in the focusing lens group. The bottom of the internal threaded cylinder is equipped with an external threaded tube, which is used to fix the directional icon and also to allow the directional icon to be detachably connected to the laser irradiation component. The bottom of the external threaded tube is equipped with a directional icon, which is used to guide the person in distress, making it easier for them to find an escape route.

[0011] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0012] 1. The laser diode in the laser irradiation component is activated by the laser power supply, and then the laser tube forms a laser that can penetrate smoke and shines on the focusing lens group, which in turn shines the laser on the directional icon, and then projects the pattern of the directional icon onto the ground to guide the person in distress, thereby improving the survival rate of the person in distress.

[0013] 2. The heat dissipation holes are used to dissipate heat from the laser diode, thereby stabilizing the working efficiency of the laser diode.

[0014] 3. The internal threaded tube is used to connect the external threaded tube to the heat dissipation housing, thereby connecting the directional icon fixed inside the external threaded tube to the laser irradiation component. The external threaded tube is used to fix the directional icon and also to allow the directional icon to be detachably connected to the laser irradiation component, which can facilitate the updating of directional indicators for different application scenarios.

[0022] In use, the laser diode 304 in the laser irradiation component 301 is activated by the laser power supply 300, and then the laser tube 303 forms a laser that can penetrate smoke and irradiates the focusing lens group 305, which in turn irradiates the directional icon 400, and then illuminates the pattern of the directional icon 400 on the ground to guide the person in distress, thereby improving the survival rate of the person in distress.

[0023] This embodiment provides a drone for pointing illumination.

[0024] As shown in Figures 1, 2, 3, and 4: The angle adjustment assembly 200 includes a pair of arc-shaped bases 203. A pad is provided on the top of each arc-shaped base 203, and it is bolted to the bottom of the quick-release connector 100. The arc-shaped bases 203 are used to fix and install the rotating shaft 204, thereby limiting the rotation of the rotating shaft 204. Each arc-shaped base 203 is inverted and mounted on the bottom of the quick-release connector 100. The rotating shaft 204 is rotatably mounted between the arc-shaped bases 203. A shaft hole is provided on each arc-shaped base 203 to rotatably engage with the rotating shaft 204. The rotating shaft 204 is used to install a connecting block 201, so that the connecting block 201 can rotate along with the rotating shaft 204. A motor 205 is connected to one end of the rotating shaft 204. The housing of the motor 205 is bolted to the bottom of the quick-release connector. A ratchet assembly can be provided at the output end of the motor 205 for lifting.

The heat dissipation housing 302 is also used to protect the components inside the laser irradiation assembly 301, thereby improving the service life of the components. The laser tube 303 is used to fix the reflectors at both ends of the resonant cavity, so that a resonant cavity is formed inside the tube. The laser diode 304 is used to generate the initial laser light source, and then the laser is irradiated to the focusing lens group 305 through the laser tube 303, and then the laser is irradiated to the pointing icon 400, and then the pattern of the pointing icon 400 is irradiated on the ground to guide the people in distress.
