[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-4 The present invention provides the following technical solution: A heavy-load fixed-wing UAV with built-in material transport and delivery device includes a fixed-wing UAV body 1, a traction component 2 is bolted to the rear side of the fixed-wing UAV body 1, and a material body 3 is arranged inside the traction component 2. The traction assembly 2 includes a rope storage box 201, an electrically driven telescopic rod 202 is fixedly connected inside the rope storage box 201, an adjusting plate 203 is fixedly connected to the bottom of the electrically driven telescopic rod 202, a cutting blade 204 is fixedly connected to the bottom of the adjusting plate 203, and a traction rope 205 is wound inside the rope storage box 201. The traction rope 205 is used in conjunction with the material body 3.

[0018] In this embodiment: A fixed-wing UAV body 1 serves as the main carrier and load-bearer of the entire delivery device, providing installation space and power supply for the traction component 2, the material carrier 3, and all electrical and mechanical components. This enables heavy-load flight and internal material transport. The traction component 2, the core actuator of the entire device, integrates rope reel storage, traction, descent control, and cutting / separation functions, ensuring stable lowering, speed buffering, and final rope breakage and release of the material carrier 3. A rope storage box 201 provides a closed housing for storing the traction rope 205, offering internal structural positioning and protecting the traction rope 205 from dust and rain, ensuring smooth cable release. An electrically driven telescopic rod 202 enables electric linear... The driving element, after being powered on, drives the adjusting plate 203 to move up and down, thereby achieving the pressing and speed control of the traction rope 205 and the cutting trigger action. The adjusting plate 203 is used as a support plate for mounting the cutting blade 204, the pressing roller 8, and the guide roller 9. It moves with the electric drive telescopic rod 202, transmits power and completes the speed control and rope cutting operation. The cutting blade 204 is used to cut the traction rope 205. Driven by the adjusting plate 203, it contacts and cuts the rope, so that the material body 3 and the traction rope 205 are completely separated from the drone. The traction rope 205 is a flexible rope connecting the rope storage box 201 and the material body 3. It is slowly released by its own weight to achieve the descent deceleration and buffering of the material body 3, avoiding high-speed impact damage to the material body 3.

[0019] Specifically, such as Figure 3 As shown, the bottom of the adjustment plate 203 has two adjustment slots 4, and the top of the inner wall of each of the two adjustment slots 4 is fixedly connected to a spring 5, and the bottom of each of the two springs 5 ​​is fixedly connected to an adjustment block 6.

[0020] Specifically, such as Figure 3 As shown, the bottom of each of the two adjusting blocks 6 is fixedly connected to a frame 7, and the inside of each of the two frames 7 is rotatably connected to a pressing roller 8.

[0021] Specifically, such as Figure 3 As shown, both downward rolling wheels 8 are in contact with the surface of the traction rope 205, and the cutting blade 204 is used in conjunction with the traction rope 205.

[0022] In this embodiment: By setting an adjustment groove 4, a movable groove is opened at the bottom of the adjustment plate 203, providing vertical movement space for the adjustment block 6. In conjunction with the spring 5, elastic clamping is achieved. By setting the spring 5, an elastic element, the adjustment block 6 is pushed downward, so that the downward rolling wheel 8 continuously presses the traction rope 205, realizing the line release damping control and achieving a slow descent effect. By setting the adjustment block 6, a movable part connecting the spring 5 and the frame 7 is set. Under the action of the spring 5, the downward rolling wheel 8 is driven to press the rope, ensuring damping stability. By setting the frame 7, a support structure for installing the downward rolling wheel 8 is set, ensuring smooth rotation and stable position of the wheel. By setting the downward rolling wheel 8, a rolling clamping part is set, the surface of the traction rope 205 is pressed under the action of the spring 5. The line release speed is controlled by friction, realizing the buffering and deceleration of the material body 3 during descent.

[0023] Specifically, such as Figure 3 , Figure 4 As shown, a guide roller 9 is fixedly connected to the rear side of the adjustment plate 203, and the rope storage box 201 is bolted to the rear side of the fixed-wing UAV body 1.

[0024] Specifically, such as Figure 3 As shown, a preset hole 10 is provided on the right side of the fixed-wing UAV body 1. An electromagnet 11 is fixedly connected inside the preset hole 10. A baffle plate 12 is snapped into the preset hole 10. A magnetic block 13 that works with the electromagnet 11 is fixedly connected to the surface of the baffle plate 12.

[0025] Specifically, such as Figure 4 As shown, a buffer pad 14 is snapped into the inner wall of the fixed-wing UAV body 1.

[0026] In this embodiment: By setting the guide roller 9, the traction rope 205 is turned and guided, avoiding rope friction and jamming, and ensuring a smooth and stable release process. By setting the preset hole 10, a material loading opening is reserved on the side of the UAV body for the insertion and removal of the material body 3. By setting the electromagnet 11, an electrically controlled magnetic attraction component, when energized, a magnetic force is generated to attract the magnetic block 13, causing the baffle plate 12 to close and seal the preset hole 10. When the power is off, the attraction is released, making it easy to open the preset hole 10 to load the material body 3. By setting the baffle plate 12, the side preset hole 10 is closed, realizing built-in storage, reducing flight wind resistance, and providing dust and water protection. By setting the magnetic block 13, in cooperation with the electromagnet 11, the baffle plate 12 is locked and released, realizing reliable sealing and convenient opening of the preset hole 10. By setting the buffer pad 14, a flexible buffer structure, the shaking and collision of the material body 3 inside the fuselage can be reduced, effectively protecting the material body 3 and the UAV body structure.

[0027] Working principle: The fixed-wing UAV body 1 serves as the overall carrying platform, providing power and structural support. The shield 12 at the pre-set hole 10 on the side is closed by electromagnet 11 and magnetic block 13. The user can open the shield 12 to put the material body 3 into the fuselage. The buffer pad 14 protects and absorbs shock for the material body 3, achieving stable built-in transport. After reaching the deployment position, the UAV body opens the bottom compartment door through its own structure. Under the action of gravity, the material body 3 pulls the traction rope 205, causing the traction rope 205 to be slowly released from the rope storage box 201. The guide roller 9 guides the traction rope 205. The guide rope 205 is guided and smoothed. The spring 5 pushes the rolling wheel 8 to elastically press the traction rope 205 through the adjusting block 6 and the frame 7. The damping friction force controls the release speed, allowing the material body 3 to achieve a smooth buffer and deceleration descent. When the material body 3 descends to the designated safe height, the electric drive telescopic rod 202 pushes the adjusting plate 203 to move down, driving the cutting blade 204 to quickly cut the traction rope 205, so that the material body 3 and the traction rope 205 are completely separated from the drone to complete the delivery. The entire process realizes the integrated and stable operation of side loading, internal storage, bottom compartment delivery, slow descent and deceleration, and rope breakage separation.

[0028] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
