Description

Technical Field

[0001] This utility model relates to the field of night navigation light technology, and more specifically, it relates to a night navigation light for unmanned aerial vehicles (UAVs). Background Technology

[0002] In existing technologies, the light body components of a drone night navigation light have several technical defects, mainly in the lack of a supine adjustment method or the inconvenience of supine adjustment. This seriously limits the practicality and safety of the night navigation light in complex flight environments.

[0003] Traditional drone navigation lights typically employ a fixed-angle design or a simple manual adjustment mechanism, which cannot provide precise elevation angle adjustments to meet the needs of different flight missions. When drones need to perform missions in complex terrain or special weather conditions, the insufficient illumination angle limits the pilot's field of vision, increasing flight risks.

[0004] Even though some improved navigation lights have limited angle adjustment capabilities, their adjustment mechanisms generally suffer from complex operation and low adjustment precision. Common bolt-fixed angle adjustments require specialized tools, making the process cumbersome and time-consuming, and unable to quickly respond to environmental changes during missions. Furthermore, the stability of the adjusted position is difficult to guarantee, and it is prone to loosening during high-speed drone flight or when encountering air current disturbances, causing the light angle to shift.

[0030] Please see Figures 1-5 A drone night navigation light includes a drone component 1, a light body component 2, a light body adjustment mechanism, a positioning auxiliary mechanism, and a positioning mechanism. The light body adjustment mechanism includes a mounting bracket 3 and a positioning pin 4. The light body component 2 is rotatably mounted on the mounting bracket 3. An arc frame 5 is mounted on the bottom end of the mounting bracket 3. The arc frame 5 has adjustment holes 6, and multiple sets of adjustment holes 6 are provided. A longitudinal plate 7 is mounted on the bottom side of the light body component 2. A positioning sleeve 8 is mounted on the side of the longitudinal plate 7. The longitudinal plate 7 is rotatably mounted on the arc frame 5. The positioning pin 4 can pass through different adjustment holes 6 and engage with the positioning sleeve 8. The positioning auxiliary mechanism includes an outer rotating frame 9 and a fixed frame 10. The outer rotating frame 9 is rotatably mounted on the outer wall of the positioning sleeve 8. The fixed frame 10 is fixedly mounted on the outer wall of the positioning sleeve 8. An embedded spring frame 11 is mounted on the fixed frame 10. A rotating block 12 is mounted on the rotating frame. Rotating rings 13 are mounted on both sides of the rotating block 12. A pressure groove 14 is opened on the rotating ring 13. The embedded spring frame 11 extends into the pressure groove 14 step by step, so that the outer rotating frame 9 rotates stably.

[0031] In this embodiment, the lamp body adjustment mechanism is responsible for adjusting the angle of the lamp body assembly 2. During operation, the lamp body assembly 2 can rotate on the mounting bracket 3, and the longitudinal plate 7 follows the lamp body assembly 2 to rotate on the arc frame 5. The arc frame 5 is provided with multiple sets of adjustment holes 6. By selecting different adjustment holes 6, the positioning pin 4 can be passed through the hole and engaged with the positioning sleeve 8, thereby realizing multi-level adjustment of the lamp body angle. This allows the lamp body to be adjusted to a suitable illumination angle according to the needs of night flight, meeting the lighting needs of different flight scenarios. The positioning auxiliary mechanism provides auxiliary positioning function for angle adjustment. The outer rotating frame 9 is limited to rotating and installed on the outer wall of the positioning sleeve 8. The embedded spring frame 11 on the fixed frame 10 cooperates with the pressure groove 14 on the rotating ring 13 on the rotating block 12. When the lamp body angle needs to be disassembled or installed, by rotating the outer rotating frame 9, the rotating block 12 drives the rotating ring 13 to rotate, and the embedded spring frame 11 extends into the pressure groove 14 step by step, generating positioning feedback. This allows the operator to perceive the position of the graded adjustment and enables the outer rotating frame 9 to rotate stably, preventing accidental rotation and enhancing the accuracy and stability of angle adjustment.

[0032] The positioning mechanism includes an internal gear ring 15 and a rotating gear block 16. The internal gear ring 15 is installed at the bottom end of the outer rotating frame 9, and the rotating gear block 16 is rotatably installed on the inner wall of the positioning sleeve 8. The side wall of the positioning pin 4 is provided with a slot 17. A bidirectional gear block 18 is meshed between the internal gear ring 15 and the rotating gear block 16. The bidirectional gear block 18 is rotatably installed in the side wall of the positioning sleeve 8. The rotation of the internal gear ring 15 causes the bidirectional gear block 18 to rotate, which drives the rotating gear block 16 to extend into or away from the slot 17.

[0033] In this embodiment, the positioning mechanism is responsible for locking the adjusted angle position. When the lamp body angle is adjusted to the correct position, the internal gear ring 15 is rotated, which drives the bidirectional gear block 18 to rotate. The bidirectional gear block 18 then drives the rotating gear block 16 to rotate, so that the rotating gear block 16 extends into the slot 17 on the side wall of the positioning pin 4 to form a mechanical lock. This ensures that the lamp body angle will not shift even under vibration conditions during the flight of the drone, and maintains a stable lighting direction.

[0034] Please see Figures 1-5As a supplementary implementation of the UAV night navigation light for the lamp body adjustment mechanism, positioning auxiliary mechanism and positioning mechanism: A base frame 19 is installed at the bottom end of the UAV component 1, and a support frame 20 is installed at the bottom end of the base frame 19. A connecting frame 21 is installed at the bottom end of the mounting frame 3, and the connecting frame 21 is installed on the base frame 19. A bearing 22 is installed on the side of the mounting frame 3. A rotating shaft 23 is installed on both sides of the lamp body, and the rotating shaft 23 is connected to the bearing 22. A connecting plate 24 is installed at the bottom end of the positioning sleeve 8, and the connecting plate 24 is fixedly installed on one end face of the longitudinal plate 7. A support ring 25 is rotatably installed at the top end of the connecting plate 24, and the top end of the support ring 25 is connected to the bottom end of the internal toothed ring 15. A space groove 26 is opened in the side wall of the positioning sleeve 8, and the rotating toothed block 16 is set to limit rotation within the space groove 26.

[0035] More specifically, the drone night navigation light is fixed to the base frame 19 of the drone component 1 via the connecting bracket 21 to ensure a secure installation. First, by rotating the inner gear ring 15, the rotating gear block 16 is moved away from the slot 17, releasing the lock of the positioning pin 4. The angle of the light body component 2 is manually adjusted so that the longitudinal plate 7 rotates to the desired position on the arc frame 5. A suitable adjustment hole 6 is selected, and the positioning pin 4 is passed through and engaged with the positioning sleeve 8. The outer rotating frame 9 is rotated, and the precise positioning feedback is provided by the engagement of the embedded spring frame 11 and the pressure groove 14. The inner gear ring 15 is rotated, and the rotating gear block 16 is driven by the bidirectional gear block 18 to extend into the slot 17 of the positioning pin 4, completing the locking. After locking, the light body is held at the set angle, providing stable illumination for the drone's night flight. When the angle needs to be readjusted, the above adjustment and locking steps are repeated.

[0036] In summary, when the overall equipment is in use or operation: when the lamp body adjustment mechanism needs to be operated, the lamp body adjustment mechanism is responsible for adjusting the angle of the lamp body assembly 2. During operation, the lamp body assembly 2 can rotate on the mounting frame 3, and the longitudinal plate 7 follows the lamp body assembly 2 to rotate on the arc frame 5. The arc frame 5 is provided with multiple sets of adjustment holes 6. By selecting different adjustment holes 6, the positioning pin 4 can be passed through the hole and engaged with the positioning sleeve 8, thereby realizing multi-level adjustment of the lamp body angle, so that the lamp body can be adjusted to a suitable illumination angle according to the needs of night flight and meet the lighting needs of different flight scenarios.

[0037] When the positioning mechanism is in operation, it is responsible for locking the adjusted angle position. After the lamp body angle is adjusted to the correct position, the internal gear ring 15 is rotated, which drives the bidirectional gear block 18 to rotate. The bidirectional gear block 18 then drives the rotating gear block 16 to rotate, so that the rotating gear block 16 extends into the slot 17 on the side wall of the positioning pin 4 to form a mechanical lock. This ensures that the lamp body angle will not shift even under vibration conditions during the flight of the drone, and maintains a stable lighting direction.

[0038] When the positioning auxiliary mechanism is required to operate, it provides auxiliary positioning function for the positioning mechanism. The outer rotating frame 9 is limited to rotate and installed on the outer wall of the positioning sleeve 8. The embedded spring frame 11 on the fixed frame 10 cooperates with the pressure groove 14 on the rotating ring 13 on the rotating block 12. When the lamp body angle needs to be disassembled or installed, the outer rotating frame 9 is rotated, the rotating block 12 drives the rotating ring 13 to rotate, and the embedded spring frame 11 extends into the pressure groove 14 step by step to generate positioning feedback, so that the operator can perceive the position of the graded adjustment, and the outer rotating frame 9 can stably drive the inner toothed ring 15 to rotate, preventing accidental rotation and enhancing the accuracy and stability of positioning adjustment.

[0039] The drone night navigation light is fixed to the base frame 19 of the drone component 1 via the connecting bracket 21, ensuring a secure installation. First, rotate the inner gear ring 15 to move the rotating gear block 16 away from the slot 17, releasing the lock of the positioning pin 4. Manually adjust the angle of the light body component 2 so that the longitudinal plate 7 rotates to the desired position on the arc frame 5. Select a suitable adjustment hole 6, pass the positioning pin 4 through it to engage with the positioning sleeve 8, and rotate the outer rotating frame 9. The engagement of the embedded spring frame 11 and the pressure groove 14 provides precise positioning feedback. Rotate the inner gear ring 15, and the bidirectional gear block 18 drives the rotating gear block 16 to extend into the slot 17 of the positioning pin 4, completing the locking. After locking, the light body remains at the set angle, providing stable illumination for the drone's night flight. When the angle needs to be readjusted, repeat the above adjustment and locking steps.

For all the fixed connections mentioned above, welding is preferred.
