Detailed Implementation

[0040] The technical solution of the present invention will now be described in detail with reference to the accompanying drawings.

[0041] This invention provides a novel skin-mounted flip-type oil-receiving lighting lamp, which consists of 5 parts: a base 1, a housing 2, a retractable assembly 3, a sector gear assembly 4, and a light source assembly 5.

[0042] The upper surface of the base 1 is attached to the aircraft skin and is screwed to the end cap of the sector gear assembly 4 by screws.

[0043] The housing 2 is used to install the take-up and take-down assembly 3, the sector gear 4, and the light source assembly 5.

[0044] The retraction assembly 3 consists of a brushless motor 301, an end cover 302, a first gear 303, a gear assembly 304, a first housing assembly 305, a second housing assembly 306, a planetary gear assembly 307, a guide device assembly 308, and a second gear 309. The brushless DC motor 301, gear assembly 303, gear assembly 304, and housing assembly 305 are all fixed to the end cover 302 with screws. The housing assembly 306 is mounted on the housing assembly 305 with screws and is screwed onto the housing 2. The planetary gear assembly 307 and gear 309 are mounted on the housing assembly 306 through the shaft of the guide device assembly 308. Finally, the power is transmitted to the gear 309, which meshes with the sector gear assembly 4 and rotates along the sector gear assembly 4.

[0045] The sector gear assembly 4 consists of a first end cover 401, a bushing 402, a second end cover 403, a bearing 404, and a sector gear 405. The first end cover 401 is screwed onto the base 1, the second end cover 403 is screwed onto the housing 2, the bearing 404 is pressed into the second end cover 403, and the bushing 402 is installed on the shaft of the sector gear 405.

[0046] The light source assembly 5 consists of a first glass screen 501, a second glass screen 502, a first lens 503, a second lens 504, a first light source printed circuit board 505, a second light source printed circuit board 506, a third light source printed circuit board 507, a first reflector 508, a second reflector 509, a light source housing 510, and a constant current driver 511.

The first glass screen 501 and the second glass screen 502 are mounted on the upper parts of the first lens 503 and the second lens 504. The first lens 503 and the second lens 504 are mounted on the upper parts of the first light source printed circuit board 505 and the second light source printed circuit board 506. The first reflector 508 and the second reflector 509 are mounted on the upper part of the third light source printed circuit board 507. All of the above components are mounted on the front side of the light source housing 510 with screws, and the constant current driver 511 is screwed onto the back side of the light source housing 510.

[0047] Specifically, when the brushless motor 301 is powered on, the power flows from the brushless motor 301 to the first gear 303, the gear assembly 304, the guide device assembly 308, the second gear 309, the sector gear 405, and the housing 2 to the light source assembly 5. By controlling the on and off of the brushless motor 301, the light source assembly 5 can be positioned at any position within the range of 0° to 90°, thereby adjusting the illumination angle according to the position of the aircraft's refueling probe, illuminating the nozzle of the refueling probe and the area in front of the probe, and ensuring that the light cone axis illuminates the tip of the cone.

[0048] Specifically, the optical system composed of the first glass screen 501, the second glass screen 502, the first lens 503, the second lens 504, the first light source printed circuit board 505, and the second light source printed circuit board 506 provides illumination for the area in front of the oil receiving probe. It adopts a two-group "LED + lens" combined illumination mode. The lens surface is processed with a scattering prism, which can form an effective scattering light spot.

[0049] Specifically, the optical system composed of the third light source printed circuit board 507, the first reflector 508, and the second reflector 509 provides illumination for the nozzle of the refueling probe. It adopts a two-group "LED + reflector" combined illumination mode, and the illumination angle is designed according to the position of the aircraft refueling probe to ensure that the light cone axis illuminates the tip of the cone.

[0050] like Figure 1 As shown, this is a schematic diagram of a new type of skin-mounted flip-type oil receiving lamp in the deployed state. The arrow points to the aircraft's flight path, and the light direction illuminates along the aircraft's flight path, thereby illuminating the nozzle of the oil receiving probe and the area in front of the probe.

[0051] like Figure 2 The diagram shows a novel skin-mounted flip-type oil-receiving lamp in its retracted state. After retraction, it fits snugly against the aircraft skin, reducing air resistance during flight.

By controlling the on and off of the brushless motor 301, the light source assembly 5 can stay at any position within the range of 0° to 90°, thereby realizing the illumination of the oil receiving probe nozzle and probe.

[0053] like Figure 4 The diagram shows a novel skin-mounted flip-type oil-receiving lamp base structure. The upper surface is fitted to the aircraft skin and screwed thereon, and is also screwed to the end cap 401 of the sector gear assembly 4.

[0054] like Figure 5 The diagram shows a novel skin-mounted flip-type oil-receiving lighting housing structure. The housing 2 is screwed to the housing assembly 306 in the retraction assembly 3, the end cap 403 in the sector gear 4, and the light source housing 510 in the light source assembly 5, and flips as a whole with the retraction assembly and the light source assembly. The housing 2 has a vulcanized rubber layer around its perimeter, allowing it to conform to the base 1 after retraction, reducing air resistance during aircraft flight.

[0055] like Figure 6 and Figure 9As shown, a novel skin-mounted flip-type oil receiving lamp retraction assembly structure and exploded view are shown. The retraction assembly provides power to the entire product and transmits the power, thereby driving the light source assembly to flip and realize the illumination of the oil receiving probe nozzle and probe.

[0056] like Figure 7 and Figure 10 The diagram shows the structure and exploded view of a novel skin-mounted flip-type oil-receiving lighting lamp with a sector gear assembly. The sector gear assembly receives and transmits the power from the retracting assembly. The sector gear 405 is fixed to the base 1, and the housing 2, the retracting assembly 3, and the light source assembly 5 all rotate within the bearing 404.

[0057] like Figure 8 and Figure 11 The diagram shows the structure and exploded view of a novel skin-mounted, flip-type refueling probe lighting light source assembly. The light source assembly provides illumination to the area in front of the refueling probe, using two sets of "LED + lens" combined lighting modes to provide area illumination to the area in front of the refueling probe, and using two sets of "LED + reflector" combined lighting modes to provide illumination to the tip of the aircraft's refueling probe cone.

[0058] Advantages of the present invention: A novel skin-mounted flip-type refueling lamp uses LED lighting and can simultaneously illuminate the nozzle of the refueling probe and the area in front of the probe.
