[0028] As Figure 1 shown in FIGS. -12, a payload compartment mounting structure of a unmanned aerial vehicle provided by the present utility model, the payload compartment mounting structure includes a front fuselage slide rail assembly 3 and a rear fuselage slide rail assembly 4 provided on the fuselage of the unmanned aerial vehicle 1, and a front payload compartment slide rail assembly 5 and a rear payload compartment slide rail assembly 6 provided on the payload compartment 2 and cooperating with the front fuselage slide rail assembly 3 and the rear fuselage slide rail assembly 4. The payload compartment 2 is mounted on the unmanned aerial vehicle 1 through the payload compartment mounting structure. Specifically, it is realized by the cooperation of the front and rear fuselage slide rail assemblies provided on the fuselage of the unmanned aerial vehicle 1 and the front and rear payload compartment slide rail assemblies provided on the payload compartment 2. The assembly of the payload compartment 2 and the fuselage of the unmanned aerial vehicle 1 is realized through the slide rail, that is, the disassembly and replacement are convenient, and at the same time, the replacement of different payloads is rapid.

[0029] The front fuselage slide rail assembly 3 includes a front fuselage slide rail 7 having an inverted U-shaped structure, an I-shaped structure, or a concave structure, and having a plurality of countersunk holes. The rear fuselage slide rail assembly 4 includes a rear fuselage slide rail 9 having an inverted U-shaped structure, an I-shaped structure, or a concave structure, with a locking tongue notch 8 at one end, and having a plurality of countersunk holes. The front load compartment slide rail assembly 5 includes a front load compartment slide rail 10 having an inverted U-shaped structure, a concave structure, or an I-shaped structure, cooperating with the front fuselage slide rail 7, and having a plurality of countersunk holes. The rear load compartment slide rail assembly 6 includes a rear load compartment slide rail 12 having an inverted U-shaped structure, a concave structure, or an I-shaped structure, cooperating with the rear fuselage slide rail 9, with a notch 11 at one end, and having a plurality of countersunk holes, and a locking unit 13 provided on the rear load compartment slide rail 12 and placed on the notch 11 for cooperating with the locking tongue notch 8. Both the front fuselage slide rail 7 and the rear fuselage slide rail 9 are installed on the fuselage of the UAV 1 by means of countersunk screws cooperating with the countersunk holes, while the front load compartment slide rail 10 and the rear load compartment slide rail 12 are also installed on the housing of the load compartment 2 by means of countersunk screws cooperating with the countersunk holes. There are also different choices in the structural selection of the front fuselage slide rail 7, the rear fuselage slide rail 9, the front load compartment slide rail 10, and the rear load compartment slide rail 12, and they can be adaptively selected according to different needs or requirements. For example, the front fuselage slide rail 7, the rear fuselage slide rail 9, the front load compartment slide rail 10, and the rear load compartment slide rail 12 all select an inverted U-shaped structure. During installation, the U-shaped openings of the front fuselage slide rail 7 and the rear fuselage slide rail 9 face each other, while the U-shaped openings of the front load compartment slide rail 10 and the rear load compartment slide rail 12 face away from each other to achieve U-shaped opening docking. After the load compartment 2 is installed in place, it is locked through the cooperation of the locking unit 13 and the locking tongue notch 8. When the front fuselage slide rail 7 and the rear fuselage slide rail 9 select an I-shaped structure, at this time, the front load compartment slide rail 20 and the rear load compartment slide rail 12 need to select a concave structure matching the I-shaped structure. During assembly, the bottom of the I-shaped structure is contained in the concave structure, enabling the concave structure to slide on the I-shaped structure, thereby realizing the installation of the load compartment 2 on the UAV 1, and after the load compartment 2 is installed in place, it is locked through the cooperation of the locking unit 13 and the locking tongue notch 8. Similarly, when the front fuselage slide rail 7 and the rear fuselage slide rail 9 select a concave structure, the front load compartment slide rail 10 and the rear load compartment slide rail 12 need to select an I-shaped structure, or a special-shaped installation can also be selected, but it is necessary to ensure that the front fuselage slide rail 7 and the front load compartment slide rail 10 are matching structures, and the rear fuselage slide rail 9 and the rear load compartment slide rail 12 are matching structures. Therefore, a variety of assembly and installations can be carried out according to different needs.

[0030] The front fuselage slide rail assembly 3 further includes a fuselage wiring unit 14 disposed inside one end of the front fuselage slide rail 7. The fuselage wiring unit 14 includes a fuselage wiring mounting base 15, a fuselage wiring PCB board 16 disposed on the fuselage mounting base 15, a fuselage wiring male terminal 17 disposed on the upper part of the fuselage wiring PCB board 16, and a busbar female socket 18 disposed at the bottom of the fuselage wiring PCB board 16. The fuselage wiring unit 14 is provided on the front fuselage slide rail assembly 3 to facilitate power taking and signal transmission of the payload compartment 2 on the unmanned aircraft 1. The fuselage wiring unit 14 is connected to the control system and power system on the unmanned aircraft 1 through the fuselage wiring male terminal 17, and is transferred to the busbar female socket 18 through the fuselage wiring PCB board 16 for docking at the payload compartment 2 end.

[0031] The front payload compartment slide rail assembly 5 further includes a payload compartment wiring unit 19 disposed inside one end of the front payload compartment slide rail 10 and used in cooperation with the fuselage wiring unit 14. The payload compartment wiring unit 19 includes a payload compartment wiring mounting base 20, a payload compartment wiring PCB board 21 disposed on the payload compartment wiring mounting base 20, a payload compartment wiring male terminal 22 disposed at the bottom of the payload compartment wiring PCB board 21, and a busbar male socket 23 disposed at the front end of the payload compartment wiring PCB board 21. The payload compartment wiring unit 19 is provided on the front payload compartment slide rail assembly 5 to facilitate power taking and signal transmission on the unmanned aircraft 1. Its principle is the same as that of the fuselage wiring unit 14, so no more description will be given here.

[0032] The locking unit 13 includes a hook seat 24 with a hollow T-shaped structure installed on the rear slide rail 12 of the load compartment. A hook 30 is arranged inside the hook seat 24 with a square structure, having a vertical chute 25 on the front, an inclined chute 26 opposite to the vertical chute 25 on the side, a spring limit hole 27 on the bottom surface, and a locking tongue 28 on the top surface. A hook return spring 31 is arranged on the hook 30 and placed inside the spring limit hole 27 to contact the hook seat 24. An unlocking button 34 is arranged on the hook 30, placed inside the vertical chute 25, penetrating through the hook 30, limited on the inclined chute 26 by a limit pin 32, and having a spring limit groove 33 at the tail end. A button return spring 35 is arranged on the unlocking button 34 and placed inside the spring limit groove 31 to contact the hook seat 24. The locking unit 13 is installed on the rear slide rail 12 of the load compartment through the hook seat 24. The locking unit 13 is locked by the cooperation of the locking tongue 28 on the hook 30 and the locking tongue slot 8 on the rear slide rail 9 of the fuselage. After the hook 30 is locked, the hook return spring 31 installed inside the spring limit hole 27 keeps the hook 30 in the locked state all the time. When unlocking, it is necessary to press the unlocking button 34 installed inside the vertical chute 25. When the unlocking button 34 is pressed, due to the interaction between the limit pin 32 and the inclined chute 26, the hook 30 will move downward, thereby compressing the hook return spring 31. At the same time, since the unlocking button 34 is pressed, the button return spring 35 is also compressed, which realizes unlocking. When the load compartment 2 is taken out, the unlocking button 34 is released, and under the action of the hook return spring 31 and the button return spring 35, the hook 30 and the unlocking button 34 will return to the starting position for continued use next time.

[0033] Relative to the load compartment 2, a load compartment panel is adhered to the shell of the load compartment 2, which can strengthen the strength of the shell of the load compartment 2. The shell of the load compartment 2 is provided with a front cover 36, an upper cover 37, and a bottom cover 38. When assembling equipment in the compartment, it is convenient for installation operation. After assembly, the front cover 36, the upper cover 37, and the bottom cover 38 can be quickly fixed to the shell of the load compartment 2 by plastic rivets, increasing the aesthetic degree and integrity. The bottom cover 38 has various forms (such as Figure 5 shown), which can meet various different loads. An adjustment stud 39 (such as Figure 3 shown) is installed on the load compartment 2. Different heights of adjustment studs 39 can be selected to adapt to various different pods, satisfying that the view of the pod is not blocked while minimizing the exposed part of the pod equipment as much as possible, thereby reducing resistance.

[0034] When installing the payload compartment 2, align the front and rear sliding rails of the payload compartment with the front and rear sliding rails of the fuselage. Slide the payload compartment 2 into the fuselage of the UAV 1 from left to right. The male copper terminal 23 on the front sliding rail 10 of the payload compartment snaps into the female copper terminal 18 on the front sliding rail 7 of the fuselage, and the payload compartment 2 is then powered on and communicates with the fuselage of the UAV 1. During the process of sliding the payload compartment 2 into the sliding rail of the fuselage of the UAV 1, the locking tongue 28 displaces downward under the force component in the diagonal direction. After being pushed to the bottom, the locking tongue 28 corresponds to the locking tongue slot 8 at the rear sliding rail 9 of the fuselage. The locking tongue 28 snaps into the locking tongue slot 8 at the rear sliding rail 9 of the fuselage under the elastic force of the locking hook return spring 31, forming a one-way lock. When removing the payload compartment 2, press the unlocking button 34 on the payload compartment 2. Under the force component of the limit pin 32 on the unlocking button 34, the locking hook 30 displaces downward and pushes the payload compartment 2 from right to left. When the locking tongue 28 exits the locking tongue slot 8 at the rear sliding rail 9 of the fuselage, the unlocking button 34 can be released, and the payload compartment 2 can be continuously pushed from right to left to remove the payload compartment 2, achieving convenient replacement of the payload compartment 2.

[0035] This installation structure of the payload compartment enables the payload compartment of the UAV to have strong compatibility and is convenient for disassembly and replacement, realizing compatibility with various pods and cameras, enabling one UAV to be equipped with multiple payloads, and allowing for rapid replacement between different payloads. In order to reduce weight, the original 3D printing is replaced with composite materials. Additionally, the structure is simple and the cost is low.

[0036] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
