Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a UAV with delivery function. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and onboard program control devices, or operated autonomously by an onboard computer, either completely or intermittently. Because UAVs have the ability to fly at high altitudes, they are often used for food delivery.

[0003] In the typical process of using drones to deliver products, the product to be delivered needs to be placed under the drone, which then provides the flight capability to carry the product for delivery. However, due to the different products to be delivered, the overall size and shape of the delivered product will change. Furthermore, since the drone needs to ascend to a high altitude, the delivered product will generate wind resistance as the drone flies, which will affect the drone's flight efficiency. Moreover, the drag generated after the product shape changes also changes, which in turn affects the stability of the drone during flight. Therefore, we propose a drone with delivery function. Utility Model Content

[0004] To address the shortcomings of existing drones with delivery functions, this utility model provides a drone with delivery functions. It has the advantage that after the product is placed on the upper part of the support plate, the first windproof sleeve and the second windproof sleeve are set on the side of the drone body. The first windproof sleeve and the second windproof sleeve reduce the drag and ensure the stability of the drone during flight, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a drone with delivery function, including a drone body, a first screw fixedly connected to the outer side of the lower part of the drone body, a threaded sleeve sleeved on the outer thread of the first screw, a support plate sleeved on the outer side of the lower end of the threaded sleeve, a height adjustment mechanism installed at the lower end of the threaded sleeve, the height adjustment mechanism synchronously controlling the adjustment of the distance between the support plate and the drone body, a first windproof sleeve and a second windproof sleeve fixedly connected to the outer sides of both ends of the drone body and the support plate, brackets fixedly connected to both sides of the upper part of the support plate, a second screw installed on the inner thread of the bracket, a connecting plate installed at the front end of the second screw, and a pressure plate installed at the front end of the connecting plate by a spring.

[0006] Preferably, the drone body is equipped with four sets of robotic arms on its exterior, and the ends of the robotic arms are equipped with fan blades that provide labor-saving support to the device.

[0007] Preferably, the height adjustment mechanism includes a first gear, which is fixedly connected to the lower part of the threaded sleeve and located at the lower end of the support plate. A second gear is movably sleeved at the middle of the lower end of the support plate, and a rack chain is sleeved on the outside of the first gear and the second gear.

[0008] Preferably, the first windshield sleeve is fitted over the outside of the second windshield sleeve, and the ends of the first windshield sleeve and the second windshield sleeve are tapered.

[0009] Preferably, the support plate has grooves on both sides, and the lower part of the pressure plate is fixedly connected to a slider, which is movably sleeved inside the groove.

[0010] Preferably, the spring is installed between the connecting plate and the pressure plate, and the product to be delivered is placed on the upper part of the support plate.

[0011] Preferably, a base frame is fixedly connected to both sides of the lower part of the support plate, and the base frame is obliquely installed on both sides of the lower end of the UAV body.

[0012] Compared with existing drones with delivery capabilities, this utility model has the following advantages:

[0013] 1. The delivery drone has a first windshield and a second windshield installed on the side of the drone body and support plate. The first windshield and the second windshield are interlocked and confined. At the same time, the first windshield and the second windshield are conical, which effectively reduces wind resistance and ensures that the drone body will not be interfered with by wind resistance during the operation, thereby improving flight efficiency and stability.

[0014] 2. The drone with delivery function places the product to be delivered on the upper part of the support plate, rotates the second screw, and the second screw drives the pressure plate to press against the side of the product to be delivered. At the same time, the pressure plate squeezes and restricts the product to be delivered. Meanwhile, the rack chain rotates, and the rack chain drives the first screw and the threaded sleeve to be threaded together and restricted. Then, when the support plate moves upward, it ensures that the product to be delivered maintains stability when it is spliced ​​between the drone body and the support plate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A delivery drone includes a drone body 1. A first screw 4 is fixedly connected to the outer side of the lower part of the drone body 1. A threaded sleeve 5 moves threadedly between the first screw 4 and the drone body 1, thereby pressing and defining the product position with a support plate 6. The threaded sleeve 5 is threaded onto the outer side of the first screw 4. The support plate 6 is installed on the outer side of the lower end of the threaded sleeve 5. The product is placed on the upper end of the support plate 6. A height adjustment mechanism is installed at the lower end of the threaded sleeve 5. The height adjustment mechanism synchronously controls the adjustment of the distance between the support plate 6 and the drone body 1. The body 1 and the support plate 6 are externally fixedly connected to the first windproof sleeve 10 and the second windproof sleeve 11. The first windproof sleeve 10 and the second windproof sleeve 11 effectively reduce wind resistance and facilitate the efficiency of the equipment during flight. The upper part of the support plate 6 is fixedly connected to the two sides of the support plate 6. The support plate 12 is internally threaded with a second screw 13. The front end of the second screw 13 is connected to a connecting plate 14. The front end of the connecting plate 14 is connected to a pressure plate 16 through a spring 15. When the second screw 13 is rotated, the second screw 13 pushes the pressure plate 16 to move inward. At the same time, the pressure plate 16 squeezes and restricts the delivered product.

[0023] Please see Figure 3The drone body 1 is equipped with four sets of robotic arms 2. The ends of the robotic arms 2 are equipped with fan blades 3 that provide force-saving assistance to the equipment. By activating the fan blades 3 installed on the outside of the drone body 1 through the robotic arms 2, the fan blades 3 drive the equipment to provide upward force-saving assistance, thereby controlling the altitude of the drone body 1 and ensuring the product can be delivered by flight.

[0024] Please see Figure 3 The height adjustment mechanism includes a first gear 7, which is fixedly connected to the lower part of the threaded sleeve 5 and located at the lower end of the support plate 6. A second gear 8 is movably sleeved on the middle of the lower end of the support plate 6. A rack chain 9 is sleeved on the outside of the first gear 7 and the second gear 8. By installing the height adjustment mechanism at the lower end of the threaded sleeve 5, rotating the second gear 8 causes the rack chain 9 to rotate, which in turn causes the four sets of first gears 7 to rotate synchronously. The first gear 7 causes the threaded sleeve 5 and the first screw 4 to move in a threaded motion. Subsequently, the height of the support plate 6 at the lower end of the drone body 1 is adjusted. Depending on the size of the product to be delivered, the drone body 1 and the support plate 6 are controlled to limit the delivery of the product, ensuring stability during positioning.

[0025] Please see Figure 1 and Figure 4 The first windshield 10 is fitted over the outside of the second windshield 11. The ends of the first windshield 10 and the second windshield 11 are tapered. The first windshield 10 and the second windshield 11 are installed on the sides of the drone body 1 and the support plate 6. The first windshield 10 is fitted over the outside of the second windshield 11. The first windshield 10 seals the outside of the second windshield 11. Since the first windshield 10 and the second windshield 11 are tapered, the first windshield 10 and the second windshield 11 reduce the resistance of the delivered products during the flight of the drone body 1, thereby ensuring the efficiency of the drone body 1 during flight.

[0026] Please see Figure 5 The support plate 6 has grooves 17 on both sides. The lower part of the pressure plate 16 is fixedly connected to a slider 18. The slider 18 is movably sleeved inside the groove 17 and installed on the upper part of the support plate 6 through the pressure plate 16. At the same time, the slider 18 installed outside the pressure plate 16 is sleeved inside the groove 17, so that the pressure plate 16 maintains stability when it moves to the sides of the product being delivered.

[0027] Please see Figure 5Spring 15 is installed between connecting plate 14 and pressure plate 16. The product to be delivered is placed on the upper part of support plate 6. By controlling the product to be delivered to be placed on the upper part of support plate 6, the second screw 13 is rotated. The second screw 13 pushes the connecting plate 14 to move inward. At the same time, the pressure plate 16 applies a squeezing force to the product to be delivered under the elastic action of spring 15. This can squeeze and limit the position of the product to be delivered, ensuring its stability during delivery.

[0028] Please see Figure 1 The support plate 6 has a base frame 19 fixedly connected to both sides of its lower part. The base frame 19 is installed obliquely on both sides of the lower end of the UAV body 1. The equipment can be docked by the base frame 19 installed on both sides of the lower part of the support plate 6.

[0029] Working principle: In use, the product to be delivered is placed on the upper part of the support plate 6. The second screw 13 is rotated, and the fan blade 3 pushes the connecting plate 14 to move inward. At the same time, the spring 15 pushes the pressure plate 16 to squeeze and limit the product to be delivered, ensuring that the position of the product to be delivered remains stable when it is pressed and limited. The second gear 8 is rotated, and the second gear 8 drives the rack chain 9 to rotate. The rack chain 9 drives the threaded sleeve 5 to perform threaded movement between the threaded sleeve 5 and the first screw 4, ensuring that the product to be delivered is clamped and limited between the drone body 1 and the support plate 6. At the same time, the first windproof sleeve 10 and the second windproof sleeve 11 are set on the side of the drone body 1. The first windproof sleeve 10 and the second windproof sleeve 11 reduce wind resistance and improve the efficiency of the equipment during flight. And through the base frame 19, the equipment can be driven to stop on the ground. By starting the fan blade 3, the fan blade 3 drives the equipment to be lifted upward for processing.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
