[0002] Certain aircraft require stealth in their aerodynamic shapes. Prior art navigation lights are often mounted protruding from the wingtips or wingtip regions, impacting stealth aircraft's aerodynamic performance to varying degrees. Objectively, aircraft require navigation lights for use at night or in poor visibility conditions. These lights provide external illumination for flight, takeoff and landing, and towing and transfer. These lights serve to indicate the aircraft's position, flight direction, and external contours, and act as a safeguard against aviation accidents. However, when illumination is not required, these lights should not protrude from the wingtips, minimizing the impact on the aircraft's aerodynamic performance. Utility Model Content

[0023] Example 1

[0024] Reference Figures 1 to 5 This embodiment provides an automatically retractable stealth anti-collision navigation light, which can meet both the lighting needs of the aircraft and the stealth requirements of the navigation light.

[0025] An automatically retractable stealth anti-collision navigation light comprises a stepper motor 100 and a transmission cylinder 300 capable of reciprocating linear motion. The stepper motor 100 is connected to a transmission screw 200, which is threadedly connected to the transmission screw 200. Two connecting rod rocker arms 400 are hinged on the transmission cylinder 300. The ends of the two connecting rod rocker arms 400 away from the transmission cylinder 300 are respectively hinged to an upper wing surface stealth anti-collision navigation light body and a lower wing surface stealth anti-collision navigation light body. The upper wing surface stealth anti-collision navigation light body and the lower wing surface stealth anti-collision navigation light body can perform linear motion toward or away from each other, and the movement direction of the navigation light body is perpendicular to the movement direction of the transmission cylinder 300.

[0026] The upper surface stealth anti-collision navigation light body and the lower surface stealth anti-collision navigation light body are respectively slidably connected in the wing body of the aircraft; when the navigation light body needs to be deployed, the stepper motor 100 is controlled to move, the transmission screw 200 rotates, and the transmission screw 200 drives the transmission cylinder 300 to move, and the movement direction of the stepper motor 100 is controlled to make the transmission cylinder 300 move horizontally in the direction of the navigation light body. The transmission cylinder 300 pushes the two connecting rod rocker arms 400 to swing, and the upper connecting rod rocker arm 400 pushes the upper surface stealth anti-collision navigation light body to slide up, and the lower connecting rod rocker arm 400 pushes the lower surface stealth anti-collision navigation light body to slide down. When the upper surface stealth anti-collision navigation light body and the lower surface stealth anti-collision navigation light body are deployed outward to the set position, the upper surface stealth anti-collision navigation light body 600 and the lower surface stealth anti-collision navigation light body 500 are opened, and at the same time the transmission cylinder 300 stops moving to achieve lighting (such as Figure 5As shown); when lighting is not needed, the stepper motor 100 is reversed, the transmission cylinder 300 moves in the opposite direction, the transmission cylinder 300 pulls the two connecting rod rocker arms 400 to swing, and the two connecting rod rocker arms 400 respectively pull the upper wing surface stealth anti-collision navigation light body 600 and the lower wing surface stealth anti-collision navigation light body 500 to move toward each other and gradually retract into the wing body. When the upper wing surface stealth anti-collision navigation light body 600 and the lower wing surface stealth anti-collision navigation light body 500 are retracted to the set position, the transmission cylinder 300 stops moving, and the upper wing surface stealth anti-collision navigation light body 600 and the lower wing surface stealth anti-collision navigation light body 500 are made stealthy (0 as shown); Figure 4 As shown); This application can meet both the lighting requirements of the aircraft and the stealth requirements of the navigation lights.

[0027] Example 2

[0028] Reference Figure 2 and Figure 3 This embodiment is based on embodiment 1, and differs from embodiment 1 in that this embodiment provides an automatically retractable stealth anti-collision navigation light, which can further realize the detection of whether the navigation light is deployed or retracted into place.

[0029] Specifically, the upper side of the lower light panel 501 at the upper end of the lower wing stealth anti-collision navigation light body is fixedly connected with an intermediate micro switch 700, and the intermediate button 701 on the intermediate micro switch 700 is set in the direction of the upper wing stealth anti-collision navigation light body. When the upper wing stealth anti-collision navigation light body and the lower wing stealth anti-collision navigation light body move toward each other, the upper wing stealth anti-collision navigation light body can press the intermediate button 701 of the intermediate micro switch 700; the lower wing stealth anti-collision navigation light body is pressed. The lower micro switch 800 and the upper micro switch 900 are fixedly connected to the lower light panel 501 at the end and the upper light panel 601 at the lower end of the upper wing stealth anti-collision navigation light body respectively. The lower button 801 of the lower micro switch 800 and the upper button 901 of the upper micro switch 900 are arranged back to back. When the lower wing stealth anti-collision navigation light body and the upper wing stealth anti-collision navigation light body are unfolded outward, the lower button 801 on the lower micro switch 800 and the upper button 901 on the upper micro switch 900 are pressed.

[0030] Specifically, it also includes a light control circuit for turning on or off the upper wing stealth anti-collision navigation light body and the lower wing stealth anti-collision navigation light body. The upper micro switch 900, the lower micro switch 800 and the middle micro switch 700 are electrically connected to the light control circuit respectively.

[0031] When the middle micro switch 700 is pressed, it means that the lower wing stealth anti-collision navigation light body and the upper wing stealth anti-collision navigation light body have been retracted into place. The middle micro switch 700 transmits the pressed signal to the light control circuit, and the light control circuit transmits the retracted signal to the aircraft's main control system. The light control circuit controls the two navigation light bodies to turn off, and the main control system controls the stepper motor 100 to turn off.

[0032] When the upper wing stealth anti-collision navigation light body and the lower wing stealth anti-collision navigation light body move away from each other, and the upper micro switch 900 and the lower button 801 of the lower micro switch 800 are both pressed, the pressed signal is transmitted to the light control circuit, and the light control circuit transmits the deployed signal to the aircraft master control system. The light control circuit controls the lower wing stealth anti-collision navigation light body and the upper wing stealth anti-collision navigation light body to open, and the aircraft master control system controls the stepper motor 100 to stop moving.

[0033] When illumination is not required and the navigation light body needs to be switched from the deployed state to the invisible state or from the invisible state to the outward deployed state, the stepping motor 100 is actively controlled by the master control system.

[0034] The process of controlling the turning on or off of the light by receiving the signal transmitted from the switch through the light control circuit is a prior art, and the process of controlling the movement of the stepper motor 100 through the master control system is also a prior art.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
