Description

Technical Field

[0001] This utility model relates to the field of navigation light technology, and in particular to a navigation light for autogyros. Background Technology

[0002] An autogyro is an aircraft that generates lift using a rotor that rotates without power. Unlike a helicopter, its rotor is not directly driven by an engine, but rather rotates due to the airflow as it moves forward. Navigation lights are essential equipment to ensure the safe operation of aircraft at night or in low-visibility conditions.

[0003] In traditional autogyros and other small aircraft, navigation light systems typically employ a fixed design, meaning the light head and body are permanently exposed. While this design is simple in structure, the fixed light head is susceptible to damage from physical impacts, collisions, or other external factors during ground operation or parking. Especially during takeoff and landing in complex environments (such as grassy or muddy ground), the light head may come into contact with ground objects, leading to lens breakage or malfunction. Furthermore, the fixed light head, constantly exposed to the air, easily accumulates dust, dirt, and rainwater, affecting the brightness and clarity of the light, particularly in humid or dusty environments, increasing maintenance frequency and costs. Utility Model Content

[0004] To overcome the aforementioned shortcomings, the technical problem to be solved is to provide a navigation light for autogyros.

[0005] The technical solution is as follows: A navigation light for an autogyro includes a fuselage, a light body, a light head, a motor, friction wheels, a heating wire, and a housing. Two mounting holes are installed at specific positions on the fuselage of the autogyro. The light body is slidably installed in the mounting holes. A light head is installed at the front end of the light body. Motors are installed on both sides of the rear of the light body. The motors are equipped with bidirectional output shafts, and friction wheels are connected to both output shafts. The friction wheels are in close contact with the inner wall of the mounting holes. The motors are electrically connected to the control system of the autogyro. A heating wire is connected in a ring around the front of the light body. A housing is connected to the front of the light body outside the heating wire. The heating wire is electrically connected to the control system of the autogyro.

[0006] As a further preferred option, the lamp body and housing have an IP67 protection rating.

[0007] As a further preferred option, it also includes a connecting ring, guide rods, springs, and protective blocks. Two guide rods are connected to the upper and lower sides of the body near the mounting hole. Protective blocks are slidably connected between adjacent guide rods. The two symmetrical protective blocks contact each other to form a barrier and are located in front of the lamp body to provide protection. Springs are fitted on the guide rods, and the two ends of the springs are connected to the protective blocks and the body, respectively. A connecting ring is connected to the front end of the lamp head. The rear sidewalls of the protective blocks are all beveled and contact the connecting rings.

[0008] As a further preferred option, it also includes a small motor, a support ring, and a wiping block. The support ring is rotatably connected to the front end of the fuselage and is inserted into two mounting holes. The small motor is installed in the middle of the fuselage. The autogyro control system is electrically connected to the small motor. The output shaft of the small motor is connected to the support ring. A wiping block is glued to the rear side wall of the support ring for cleaning the lamp head lens.

[0009] As a further preferred solution, both the support ring and the wiping block have slots aligned with the mounting holes. When not in use, these slots will not affect the normal emission of the lamp head light.

[0010] As a further preferred option, the heating wire, wiping block, and motor are designed in a modular fashion.

[0011] Compared with the prior art, the present invention has the following advantages: 1. The lamp body and lamp head adopt a sliding design and are installed in the mounting hole at a specific position on the fuselage. When not in use, the lamp head retracts into the mounting hole, avoiding damage from physical impact, collision or other external factors during ground operation or parking. When illumination is needed, the lamp body can be quickly and automatically extended to ensure that the pilot has a clear vision at critical moments and improve flight safety.

[0012] 2. The heating wire design effectively prevents fogging and icing of the lamp head lens in cold or humid environments, maintaining the lens's transparency. By precisely controlling the temperature of the heating wire, the system can maintain the brightness and clarity of the light under adverse weather conditions, further enhancing flight safety and reliability.

[0013] 3. The protective block is designed to automatically block the mounting hole when not in use, protecting the light body and head from dust, rain, and physical impact. When the navigation light needs to be used, the protective block can be automatically pushed open through the cooperation of the connecting ring and the protective block. After use, the light body retracts and the protective block closes again, restoring protection to the mounting hole. This achieves automated opening and closing, simplifies the operation process, and improves the reliability and durability of the system.

[0014] 4. A small motor is set as the power source to drive the wiping block to rotate, which can automatically clean the lens of the lamp head. This function can clean the lens before or after use, maintain the clarity of the lens, reduce the need for manual cleaning, and reduce maintenance frequency and cost. Attached Figure Description

[0022] Although this invention may be described with respect to a particular application or industry, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0023] Example: A navigation light for an autogyro, such as Figures 1-4As shown, the autogyro includes a fuselage 1, a lamp body 2, a lamp head 3, a motor 4, friction wheels 5, a heating wire 6, and a housing 8. Two mounting holes 101 are installed at specific locations on the fuselage 1. The lamp body 2 is slidably mounted within the mounting holes 101. A lamp head 3 is mounted on the front end of each lamp body 2. Motors 4 are bolted to the left and right sides of the rear of the lamp body 2. Each motor 4 is equipped with a bidirectional output shaft, and friction wheels 5 are connected to both output shafts. The friction wheels 5 are in close contact with the inner wall of the mounting holes 101. Motors 4 are electrically connected to the autogyro's control system. When the lamp body 2 is needed to provide illumination for the autogyro, the control system commands motors 4 to start. The rotation of its output shaft drives the friction wheels 5 to rotate, which, through friction with the inner wall of the mounting holes 101, propels the lamp body 2 forward to a position parallel to the port of the mounting holes 101. At this point, the lamp head 3 is exposed and begins to emit light, providing necessary illumination to help the pilot in low-light conditions. After viewing the ground conditions and path ahead, the control system reverses the motor 4 and the friction wheel 5, using friction to return the lamp body 2 and lamp head 3 to their initial positions, away from the mounting hole 101 port, thus protecting the lamp from external environmental influences. To prevent fogging or icing on the lens of the lamp head 3, a heating wire 6 is connected to the front of the lamp body 2. A housing 8 is snapped onto the front of the lamp body 2 outside the heating wire 6. The heating wire 6 is electrically connected to the control system of the autogyro and can be activated as needed to precisely control the temperature to maintain a dry environment inside the mounting hole 101. After drying, the control system will promptly shut off the heating wire 6 to save energy. The lamp body 2 and housing 8 have an IP67 protection rating, effectively waterproofing and dustproofing, and can operate normally under extreme temperatures. Key components are made of corrosion-resistant stainless steel and high-strength composite materials to ensure long-term stability in salt spray, humidity, and chemical environments.

[0024] like Figures 1-3As shown, it also includes a connecting ring 7, guide rods 9, springs 10, and protective blocks 11. Two guide rods 9 are welded to the upper and lower sides of the body 1 near the mounting hole 101. Protective blocks 11 are slidably connected between adjacent guide rods 9. The two symmetrical protective blocks 11 contact each other to form a barrier, blocking the mounting hole 101. They are also located in front of the lamp body 2, providing protection. Springs 10 are fitted onto each guide rod 9, with both ends of the springs 10 connected to the protective blocks 11 and the body 1, respectively. Connecting rings 7 are welded to the front end of the lamp head 3. The rear sidewalls of the protective blocks 11 are all beveled. The lower protective block 11 has a V-shaped structure formed by its inclined surface to cooperate with the connecting ring 7 at the front end of the lamp head 3. When the lamp body 2 and the lamp head 3 are pushed forward, the connecting ring 7 first contacts the inclined surface of the protective block 11, pushing the protective block 11 to open outward and compressing the spring 10 so that the protective block 11 no longer blocks the mounting hole 101 channel. After the lamp head 3 moves to the front port position, it provides the lighting function. After use, the lamp body 2 and the lamp head 3 move backward to reset, the connecting ring 7 and the protective block 11 disengage, the spring 10 rebounds to reset, and the protective block 11 closes again to restore the protection of the lamp body 2.

[0025] like Figures 5-6 As shown, it also includes a small motor 12, a support ring 13, and a wiping block 14. The support ring 13 is rotatably connected to the front end of the fuselage 1, and the support ring 13 is inserted into two mounting holes 101. The small motor 12 is installed in the middle of the fuselage 1 by bolts. The autogyro control system is electrically connected to the small motor 12. The output shaft of the small motor 12 is connected to the support ring 13. The wiping block 14 is glued to the rear side wall of the support ring 13 for cleaning the lens of the lamp head 3. Both the support ring 13 and the wiping block 14 have openings. The slots aligned with the mounting holes 101 do not affect the normal emission of light from the lamp head 3 when not in use. When the lamp body 2 and the lamp head 3 are pushed forward to the port position, the wiping block 14 aligns with the lamp head 3. The small motor 12 is started by the control system, and the output shaft rotates to drive the support ring 13 and the wiping block 14 to rotate, thereby wiping the lens of the lamp head 3 and ensuring the lighting brightness. After cleaning, the support ring 13 and the wiping block 14 rotate back to the initial angle, and the small motor 12 is then turned off.

[0026] The heating wire 6, wiping block 14 and motor 4 adopt a modular design and can all be replaced independently, which greatly simplifies the maintenance process.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
