[0031] As shown in the figure Figure 5As shown, the express delivery box fixing mechanism 6 in the utility model includes the first fixed plate 601 and the second fixed plate 602 arranged at the bottom of the machine body 1 and fixedly connected with the machine body 1, the control motor 603 is fixedly connected to the side of the first fixed plate 601 away from the second fixed plate 602, the output end of the control motor 603 penetrates through the lead screw 604 rotatably connected with the second fixed plate 602 through the first fixed plate 601, the movable plate 605 slidably connected with the machine body 1 is threadedly connected on the lead screw 604, two first right-angle clamping plates 606 are fixedly connected at the bottom of the first fixed plate 601, and the second right-angle clamping plate 607 is fixedly connected at the bottom of the movable plate 605. The first fixed plate 601 and the second fixed plate 602 are respectively located at both ends of the bottom of the machine body 1, and the lead screw 604 is rotatably connected with the second fixed plate 602 through the bearing 608 at the end away from the first fixed plate 601. Two guide sliding blocks 609 are fixedly connected at the top of the movable plate 605, and two guide sliding grooves for the sliding of the two guide sliding blocks 609 are arranged at the bottom of the machine body 1. The express delivery box 5 is located between the second right-angle clamping plate 607 and the two first right-angle clamping plates 606, and the second clamping groove matched with the second right-angle clamping plate 607 and the two first clamping grooves matched with the two first right-angle clamping plates 606 are respectively arranged at the top of the two sides of the express delivery box 5.

[0032] The utility model drives the lead screw 604 to rotate through the control motor 603, the movable plate 605 is driven by the lead screw 604 to slide along the guide sliding groove, and the second right-angle clamping plate 607 at the bottom of the movable plate 605 moves accordingly, so that the express delivery box 5 is quickly clamped and released.

[0033] As Figure 6As shown, the damping type support mechanism 7 in the utility model includes the rack mounting seat 701 installed at the bottom of both ends of the machine body 1, the rack mounting seat 701 bottom is installed through the fastening bolt and is provided with the rack column 702, the lower end of the rack column 702 is sleeved with the rack sleeve 703, the bottom of the rack sleeve 703 is fixedly provided with the support bottom column 708, and the support bottom column 708 is fixedly sleeved with the rubber sleeve 707 at both ends. The upper end of the rack sleeve 703 is provided with the fixed groove 704, and the lower end of the rack column 702 is located in the fixed groove 704, and the bottom end of the rack column 702 is connected with the rack sleeve 703 through the damping rod 705 and the damping spring 706. The damping rod 705 and the damping spring 706 are located in the fixed groove 704, and the damping spring 706 is sleeved outside the damping rod 705.

[0034] The damping rod 705 and the damping spring 706 can effectively absorb the impact force generated when the unmanned aerial vehicle lands and delivers through the double action. When the unmanned aerial vehicle lands, the damping spring 706 is first compressed to absorb most of the impact force, and then the damping rod 705 plays a role to slow down the rebound speed of the spring, further disperses and absorbs the remaining impact force, ensures that the unmanned aerial vehicle can land smoothly, and avoids damaging the machine body and the express delivery box. At the same time, the setting of the rubber sleeve 707 also increases the friction between the support bottom column 708 and the ground, improves the stability of the unmanned aerial vehicle, and prevents sliding or turning over during landing. The design of the damping type support mechanism 7 not only improves the landing safety of the unmanned aerial vehicle, but also prolongs the service life of the machine body, and provides a strong guarantee for the smooth delivery of express delivery.

[0035] Working principle: when the unmanned aerial vehicle is ready to take off, the control motor 403 is connected to the power supply, and the six driving motors 401 start to work, and the rotors 402 are quickly rotated through the output end drive to generate enough lift to make the unmanned aerial vehicle rise from the ground. The navigation and positioning system of the unmanned aerial vehicle is started, and through the GPS, inertial measurement unit (IMU) and visual sensor and other equipment, accurate navigation and positioning are carried out to ensure that the unmanned aerial vehicle can fly to the designated delivery point according to the predetermined path and speed.

[0036] Fixing express delivery box: when the unmanned aerial vehicle loads the express delivery box 5, the control motor 603 rotates in the positive direction to drive the screw rod 604 to rotate. The rotation of the screw rod 604 makes the movable plate 605 move along the guide sliding groove at the bottom of the machine body 1 to the first fixed plate 601. The second right-angle clamp plate 607 at the bottom of the movable plate 605 moves, and the second clamping groove at the top of the express delivery box 5 is matched. At the same time, the two first right-angle clamp plates 606 are also matched with the two first clamping grooves at the top of the express delivery box 5, so that the express delivery box 5 is stably fixed.

[0037] Release express delivery box: when the UAV arrives at the delivery point to prepare to deliver the express goods, the control motor 603 is reversed, driving the lead screw 604 to rotate in reverse. The reverse rotation of the lead screw 604 causes the movable plate 605 to move away from the first fixed plate 601 along the guide chute. The second right-angle clamping plate 607 at the bottom of the movable plate 605 is disengaged from the second clamping groove at the top of the express delivery box 5, and the two first right-angle clamping plates 606 are also disengaged from the two first clamping grooves at the top of the express delivery box 5. The express delivery box 5 falls smoothly from the bottom of the UAV under the action of gravity, completing the delivery of the express goods.

[0038] When the UAV completes the delivery task and prepares to land, the speed and height of the UAV are precisely controlled through the navigation and positioning system, allowing it to descend smoothly to the ground. During the landing process, the shock-absorbing support mechanism 7 begins to play a role. First, the rubber sleeve 707 on the support column 708 comes into contact with the ground, increasing friction and preventing the UAV from sliding or tipping over. As the UAV continues to descend, the frame column 702 moves towards the inside of the frame sleeve 703, and the shock-absorbing spring 706 is compressed, absorbing most of the impact force. Subsequently, the damping rod 705 slows down the rebound speed of the spring through the damper inside it, further dispersing and absorbing the remaining impact force, ensuring that the UAV can land smoothly and reducing damage to the body and internal equipment. Through this double damping mechanism, the UAV can maintain good stability and safety in various complex terrains and hard landing conditions.

[0039] The above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for part of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
