Conventional optoelectronic pods are usually directly installed outside the fuselage, or the hatch for installing the optoelectronic pod opens outwards. Such an installation method of the optoelectronic pod will increase additional air resistance during flight, resulting in a decrease in flight efficiency and a shortening of the in-air time. In addition, the conventional installation method of the optoelectronic pod may also increase the risk of damage to the optoelectronic pod during flight and landing, and will increase the operation difficulty of the optoelectronic pod during emergency recovery.

[0033] The present invention can be further clearly understood through the following specific embodiments of the present invention, but they do not limit the present invention.

[0034] As Figures 1 to 11 shown, an optoelectronic pod installation device having a retractable hatch door and a lifting mechanism, the installation device includes a retractable hatch door and a lifting mechanism, wherein the position of the retractable hatch door is below the position of the lifting mechanism.

[0035] Embodiment 1

[0036] As Figures 1 to 7 shown, the retractable hatch door includes a hatch door retraction and extension mechanism, the hatch door retraction and extension mechanism includes a body bottom plate 1 provided at the bottom of the lifting mechanism, wherein the body bottom plate 1 is provided with a convex curved surface, and the retractable first hatch door 2 and second hatch door 3 are embedded and installed in the body bottom plate 1. When it is necessary to open the first hatch door 2 and second hatch door 3, the first hatch door 2 and second hatch door 3 slide open in opposite directions at the same time; when it is necessary to retract and close the first hatch door 2 and second hatch door 3, the first hatch door 2 and second hatch door 3 slide closed in the same direction at the same time.

[0037] Among them, the first hatch 2 and the second hatch 3 are both connected to the fuselage bottom plate 1 through gooseneck hinges 4 fixedly installed on the fuselage bottom plate 1. One end of the gooseneck hinge 4 is hingedly connected to a baffle 5 arranged above the fuselage bottom plate 1 and on the same side as the gooseneck hinge 4. Specifically, to achieve the effect of hingedly connecting one end of the gooseneck hinge 4 to the baffle 5, a groove 12 is cut on the baffle 5 body, and slot holes 13 are opened on both sides of the groove 12. One end of the gooseneck hinge 4 is inserted into the slot holes 13 to be hingedly connected to the baffle 5. And a hatch motor 14 for driving the gooseneck hinge 4 to rotate is installed on the baffle 5. The other end of the gooseneck hinge 4 is fixedly connected to the first hatch 2 on the corresponding side and the fuselage bottom plate 1 on the same side as the first hatch 2, and is simultaneously fixedly connected to the second hatch 3 on the corresponding side and the fuselage bottom plate 1 on the same side as the second hatch 3. In this way, the first hatch 2 and the second hatch 3 are respectively connected to the corresponding gooseneck hinges 4.

[0038] Furthermore, hatch inner retraction slide rails 6 connected to the baffle 5 are fixedly installed on both sides of the fuselage bottom plate 1 and the first hatch 2 and the second hatch 3 in the same side of the sliding direction. The hatch inner retraction slide rails 6 are arranged in an inclined plane, and the inclined plane of the hatch inner retraction slide rails 6 is adapted to the convex curved surface of the fuselage bottom plate 1. The end of the baffle 5 is fixedly connected to the end of the hatch inner retraction slide rail 6 through a fixing screw 15. First sliding blocks 7 and second sliding blocks 8 for respectively driving the first hatch 2 and the second hatch 3 to slide along the corresponding hatch inner retraction slide rails 6 are installed at the positions where the first hatch 2 and the second hatch 3 are in contact. Among them, one end of the first sliding block 7 is fixed on the first hatch 2, and the other end of the first sliding block 7 can reciprocally slide along the corresponding hatch inner retraction slide rail 6; one end of the second sliding block 8 is fixed on the second hatch 3, and the other end of the second sliding block 8 can reciprocally slide along the corresponding hatch inner retraction slide rail 6.

[0039] In the first embodiment, the retraction and extension effect of the retractable hatch can be achieved. The specific retraction and extension principle of the retractable hatch is as follows:

[0040] Start the hatch motor 14, and the gooseneck hinges 4 respectively connected to the first hatch 2 and the second hatch 3 rotate simultaneously. The first sliding block 7 drives the first hatch 2 to slide outward in the corresponding hatch inner retraction slide rail 6. At the same time, the second sliding block 8 drives the second hatch 3 to slide outward in the corresponding hatch inner retraction slide rail 6. At this time, the first hatch 2 and the second hatch 3 slide in opposite directions along the corresponding hatch inner retraction slide rails 6 respectively, thereby realizing the opening of the first hatch 2 and the second hatch 3; turn off the hatch motor 14, the first hatch 2 and the second hatch 3 slide in the same direction along the corresponding hatch inner retraction slide rails 6 by the first sliding block 7 and the second sliding block 8 respectively until the first hatch 2 and the second hatch 3 are in contact, and the gooseneck hinges 4 respectively connected to the first hatch 2 and the second hatch 3 stop rotating, thereby realizing the closing of the first hatch 2 and the second hatch 3.

[0041] In the first embodiment, after opening the first hatch 2 and the second hatch 3, the optoelectronic pod 11 can descend along the lifting mechanism to perform tasks outside the retractable hatch. After the tasks are completed, the optoelectronic pod 11 ascends along the lifting mechanism to the inside of the retractable hatch, and then the first hatch 2 and the second hatch 3 are closed. Such a design of the retractable hatch can reduce the air resistance of the aircraft during flight, improve the flight efficiency, and extend the hovering time.

[0042] Embodiment Two

[0043] As Figures 1 to 5 、 Figures 8 to 9 shown, the lifting mechanism includes lifting positioning rods 9 fixedly installed on both sides of the surface of the retractable slide rail 6 of each hatch. The top of the lifting positioning rod 9 is equipped with a carrier 10 that can move up and down along the lifting positioning rod 9, and an optoelectronic pod 11 is fixedly installed on the carrier 10.

[0044] Among them, mounting holes 23 are symmetrically opened on both sides of the upper end surface of the carrier 10. The mounting holes 23 cooperate with the corresponding lifting positioning rods 9 so that the top of the lifting positioning rod 9 penetrates through the mounting holes 23 to enable the carrier 10 to move up and down along the lifting positioning rod 9. Through holes 24 are opened at positions between the two mounting holes 23 on both sides of the upper end surface of the carrier 10.

[0045] The lifting mechanism further includes a worm 16 installed between the lifting positioning rods 9 on both sides of the surface of the retractable slide rail 6 of the hatch. The bottom end of each worm 16 is fixed in the docking hole 17 on the corresponding retractable slide rail 6 of the hatch. The top of each worm 16 penetrates through the carrier 10 through the through hole 24. The top of each worm 16 penetrates through a reduction gearbox 18. A transmission shaft 20 is installed between the two reduction gearboxes 18. Both ends of the transmission shaft 20 penetrate through the corresponding reduction gearbox 18 respectively. One end of the transmission shaft 20 is connected to a stepping motor 21 that drives the transmission shaft 20 to rotate.

[0046] As Figure 10 and Figure 11 shown, an output gear 19 meshing with the top of the worm 16 is installed in each reduction gearbox 18. The transmission shaft 20 drives the output gear 19 to rotate and the output gear 19 drives the corresponding worm 16 to rotate.

[0047] In order to enable the carrier 10 carrying the optoelectronic pod 11 to accurately ascend and descend along the worm 16, a synchronous flange 22 for positioning the worm 16 is installed at a position above the carrier 10 on each worm 16.

[0048] In the second embodiment, the lifting of the optoelectronic pod 11 can be realized. The specific lifting principle of the optoelectronic pod 11 is as follows:

[0049] The retractable hatch is opened according to the retraction and extension principle of the retractable hatch in Embodiment 1. The stepping motor 21 is started, and the transmission shaft 20 drives the reduction gearbox 18 to rotate. The output gear 19 drives the worm 16 meshing with it to rotate, driving the synchronous flange 22 to descend or ascend. The carrier 10 carrying the optoelectronic pod 11 descends along the lifting positioning rod 9 outside the retractable hatch or ascends along the lifting positioning rod 9 into the retractable hatch.

[0050] Among them, the state where the optoelectronic pod 11 descends outside the retractable hatch is as shown in Figure 12 The state where the optoelectronic pod 11 ascends into the retractable hatch and the first hatch 2 and the second hatch 3 are closed is as shown in Figure 1 , Figure 2 or Figure 3 shown.

[0051] In the present invention, the optoelectronic pod 11 can be retracted into the interior of the aircraft fuselage or an area near the interior through the retractable hatch. During the flight of the aircraft, the first hatch 2 and the second hatch 3 are in a closed state, and the optoelectronic pod 11 is in a retracted state. In this way, the air resistance during the flight of the aircraft can be significantly reduced, thereby improving the flight efficiency and extending the hovering time of the aircraft. When the optoelectronic pod 11 needs to perform tasks, the retractable hatch is opened, and the optoelectronic pod 11 is lowered outside the retractable hatch by using the lifting mechanism. In addition, the design of the retractable hatch enables the optoelectronic pod 11 to be more compactly stored inside the fuselage when it does not need to work, improving the spatial layout of the aircraft, making the overall structure of the aircraft more compact and reasonable, and increasing the space utilization rate.

[0052] In addition, by reducing the flight resistance and optimizing the spatial layout, the mission execution efficiency and flexibility of the aircraft carrying the optoelectronic pod 11 can be improved, enabling the aircraft to respond to mission requirements faster and perform tasks such as reconnaissance, monitoring, and positioning more accurately.

[0053] Furthermore, the design of the retractable hatch can effectively reduce the risk of damage to the optoelectronic pod 11 during flight and landing, and also reduce the operation difficulty of the emergency recovery of the optoelectronic pod 11, improving the overall operation safety, and ensuring the safe and stable flight of the aircraft in complex environments. In an emergency, the retraction and extension principle of the retractable hatch in the above-mentioned Embodiment 1 and the lifting principle of the optoelectronic pod 11 in Embodiment 2 can be used to complete the recovery of the optoelectronic pod 11.

[0054] The above is only the implementation mode of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
