Description

Technical Field

[0001] This invention relates to the field of logistics delivery drones, specifically an automated urban logistics delivery drone device. Background Technology

[0002] Logistics delivery drones are unmanned aerial vehicles controlled by radio remote control equipment and onboard program control devices. They are specifically designed for the logistics field to achieve more efficient, flexible, and convenient cargo transportation and delivery services. Currently, most logistics delivery drones require human assistance to secure the delivery boxes to the bottom of the drone. After the drone arrives at the designated location, manual assistance is also needed to remove the boxes from the drone. This results in relatively low automation and increases the labor intensity of workers. Secondly, logistics drones experience significant impact when landing with cargo. Existing drone landing cushioning structures mostly rely on rubber pads, which are not very effective at absorbing shock, especially when the cargo is heavy. Without a better cushioning structure, not only can the drone itself be damaged, but the cargo may also be damaged in the impact. Summary of the Invention

[0003] The purpose of this invention is to provide an automated urban logistics delivery drone device in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an automated urban logistics delivery drone device, comprising a drone, wherein a base plate is installed on the bottom of the drone;

[0005] Two sets of support leg assemblies are symmetrically distributed at both ends of the bottom of the base plate, and both sets of support leg assemblies are hinged to the base plate through connecting seats. Each support leg assembly includes a support leg frame with a rectangular frame structure and a fixing plate fixedly connected to the lower end of the support leg frame. Four sets of shock absorbers are located below the four corners of the bottom of the base plate. The lower end of each shock absorber is hinged to the upper end of the support leg frame, and a fixed rod is hinged to the upper end of each shock absorber. Both ends of the fixed rod are fixedly connected to the bottom of the base plate. A clamping mechanism is installed at the bottom center of the base plate and is located between the two sets of support leg assemblies. It is used to clamp or release the logistics box in conjunction with the lifting and lowering of the drone and the weight of the material box. When the drone takes off and ascends, the lower ends of the two sets of support leg assemblies will be displaced under the restoring force of the shock absorber and the self-weight of the lower ends of the support leg assemblies, so that the two sets of support leg assemblies are relatively parallel to each other on both sides of the material box, so that the two fixed plates respectively hold the bottom ends of the material box.

[0006] As a further embodiment of the present invention: the clamping mechanism includes a fixed seat fixedly connected to the middle of the bottom end of the base plate, a cross frame provided below the fixed seat, a connecting rod assembly hinged between the fixed seat and the cross frame, movable seats slidably installed at both ends of the cross frame, a clamping plate installed on the inner side of the movable seat, a connecting assembly connected between the movable seat and the bottom end of the connecting rod assembly, a connecting block provided between the cross frame and the fixed seat, and an adsorption assembly adsorbingly connected between the connecting block and the fixed seat.

[0007] As a further embodiment of the present invention: the linkage assembly includes two sets of symmetrically arranged first linkages and second linkages. The upper ends of the two sets of first linkages are alternately hinged to the outer ends of the fixed base via shafts. The two sets of second linkages are respectively hinged to the lower ends of the two sets of first linkages, and the two sets of second linkages are arranged in a cross configuration. The intersection of the two sets of second linkages is hinged via shafts. The connecting block is located inside the intersection of the two sets of second linkages and is fixedly connected to the inner end of the corresponding hinged shaft.

[0008] As a further embodiment of the present invention: the cross frame has a hollow cuboid structure, and two first through slots and two second through slots are provided in the length direction of the cross frame. The two first through slots are symmetrically provided at both ends of the cross frame, and the two second through slots are located between the two first through slots. The two second through slots are symmetrically provided on the outer wall of the cross frame with the middle part of the cross frame as the axis.

[0009] As a further embodiment of the present invention: the connecting assembly includes a connector located at one end inside the crossbeam, and both ends of the connector are fixedly connected to a shaft column, one of the shaft columns is located in the first through groove and is fixedly connected to the movable seat, and the other shaft column is located in the second through groove and is hinged to the lower end of the second connecting rod.

[0010] As a further embodiment of the present invention: both ends of the clamping plate are integrally formed with connecting plates, the connecting plates are L-shaped, the distance between the inner walls of the opposing surfaces of the two connecting plates is greater than the length of the cuboid material box, and rubber pads are adhered to the inner walls of the clamping plate and the two connecting plates.

[0011] As a further embodiment of the present invention: the adsorption assembly includes an electromagnet installed at the bottom of the fixed base, and an iron block fixedly connected to the top of the connecting block, the iron block being located directly below the electromagnet.

[0012] As a further embodiment of the present invention: the support leg assembly includes a support leg frame with a rectangular frame structure, and two connecting columns are symmetrically arranged on the upper inner side wall of the support leg frame, and the lower end of the shock absorber is hinged to the connecting columns.

[0013] As a further embodiment of the present invention: two rollers are symmetrically sleeved at the bottom end of the support leg frame, and the rollers are located below the fixing plate.

[0014] As a further embodiment of the present invention: a magnet is embedded in the back of the connecting plate, and the outer walls of the support leg frame are symmetrically provided with docking grooves that match the width of the connecting plate. When the support leg frame is perpendicular to the ground, the docking grooves are in contact with the magnets. The support leg frame is made of iron.

[0015] Compared with the prior art, the beneficial effects of the present invention are: By incorporating a clamping mechanism, the drone can automatically clamp or release the logistics box during takeoff and landing, eliminating the need for manual assistance in loading and unloading the material box and reducing the labor intensity of workers. Secondly, the combination of support leg components and shock absorbers forms a buffer and shock absorption structure, reducing the impact force on the drone when it lands, thereby increasing the service life of the drone and ensuring that the items inside the material box are not damaged by impact. In addition, when the drone takes off, the lower end of the support leg components will move inward, while the fixing plate will be moved to the bottom sides of the logistics box to hold the bottom of the logistics box, preventing relative sliding between the logistics box and the magnets on the inner wall of the clamping plate during the drone's flight, which could lead to the risk of the logistics box falling off.

[0018] 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.

[0019] Please see Figures 1 to 8 In this embodiment of the invention, an automated urban logistics delivery drone device includes a drone 1, and a base plate 2 is installed on the bottom of the drone 1. Two sets of support leg assemblies 3 are symmetrically distributed at both ends of the bottom of the base plate 2, and both sets of support leg assemblies 3 are hinged to the base plate 2 through connecting seats 7. The support leg assembly 3 includes a rectangular frame structure support leg frame 301 and a fixing plate 304 fixedly connected to the lower end of the support leg frame 301. Four sets of shock absorbers 4 are located below the four corners of the bottom of the base plate 2. The lower end of the shock absorber 4 is hinged to the upper end of the support leg 301. The upper end of the shock absorber 4 is hinged to a fixed rod 6. The two ends of the fixed rod 6 are fixedly connected to the bottom of the base plate 2. The clamping mechanism 5 is installed at the bottom center of the base plate 2 and is located between the two sets of support leg assemblies 3. It is used to clamp or release the logistics box in conjunction with the lifting of the drone 1 and the weight of the material box. When the drone 1 takes off and ascends, the lower ends of the two sets of support leg assemblies 3 will be displaced under the restoring force of the shock absorber 4 and the self-weight of the lower ends of the support leg assemblies 3, so that the two sets of support leg assemblies 3 are relatively parallel to each other on both sides of the material box, so that the two fixed plates 304 respectively hold the bottom ends of the material box.

[0020] The clamping mechanism 5 includes a fixed base 501 fixedly connected to the middle of the bottom end of the base plate 2. A cross frame 503 is provided below the fixed base 501. A connecting rod assembly 504 is hinged between the fixed base 501 and the cross frame 503. Movable seats 505 are slidably installed at both ends of the cross frame 503. A clamping plate 507 is installed on the inner side of the movable seat 505. A connecting assembly 506 is connected between the movable seat 505 and the bottom end of the connecting rod assembly 504. A connecting block 502 is provided between the cross frame 503 and the fixed base 501. An adsorption assembly 508 is adsorbed between the connecting block 502 and the fixed base 501.

[0021] In this embodiment: by setting up the clamping mechanism 5, the UAV 1 can automatically clamp or release the logistics box during take-off and landing, eliminating the need for manual assistance in loading and unloading the material box and reducing the labor intensity of the staff. Secondly, by setting up the support leg assembly 3 and the shock absorber 4 to form a buffer and shock absorption structure, the impact force on the UAV 1 when landing is reduced, thereby improving the service life of the UAV 1 and ensuring that the items in the material box are not damaged by impact. In addition, when the UAV 1 takes off, the lower end of the support leg assembly 3 will move inward, and at the same time move the fixing plate 304 to the bottom sides of the logistics box to hold the bottom of the logistics box, so as to prevent the logistics box from sliding relative to the magnet 5073 on the inner wall of the clamping plate 507 during the flight of the UAV 1, which would lead to the risk of the logistics box falling off.

[0022] This solution mainly consists of a drone 1, a support leg assembly 3, a shock absorber 4, and a clamping mechanism 5. The drone 1 is an existing model of a flying drone capable of carrying a relatively heavy amount of logistics goods. The support leg assembly 3 is provided in two sets, which are symmetrically distributed at both ends of the bottom of the base plate 2. The upper ends of the support leg assemblies 3 at both ends are hinged to the bottom of the base plate 2 through connecting seats 7. In addition, a shock absorber 4 is installed between the base plate 2 and the support leg assembly 3 to buffer the outward movement of the lower end of the support leg assembly 3, and also to buffer the impact force when the drone 1 lands. The shock absorber 4 is an existing shock absorber with a spring structure. Its specific structure is existing technology and will not be described in detail again. In addition, the clamping mechanism 5 in this solution is installed at the bottom of the base plate 2 and located between the two sets of support leg assemblies 3. The clamping mechanism 5 mainly consists of two sets of crossbeams 503, a connecting rod assembly 504, a movable seat 505, a connecting assembly 506, a clamping plate 507, and an adsorption assembly 508. The two crossbeams 503 are slidably connected to the outer walls of both ends of the movable seat 505. The connecting rod assembly 504 adopts the existing lifting connecting rod structure. When the UAV 1 takes off, it will change the shape of the connecting rod assembly 504, causing the two ends of the bottom of the connecting rod assembly 504 to move inward. Then, through the connecting assembly 506, it will drive the two movable seats 505 to move synchronously and move closer together, and clamp the logistics box by friction with the outer wall of the logistics box. Similarly, when the UAV 1 lands, it will push the two movable seats 505 to move outward and contact the clamping of the material box.

[0023] Please refer to this carefully. Figures 1 to 8 The linkage assembly 504 includes two sets of symmetrically arranged first linkages 5041 and second linkages 5042. The upper ends of the two sets of first linkages 5041 are alternately hinged to the outer ends of the fixed base 501 via shafts. The two sets of second linkages 5042 are respectively hinged to the lower ends of the two sets of first linkages 5041, and the two sets of second linkages 5042 are arranged in a cross pattern. The intersection of the two sets of second linkages 5042 is hinged via shafts. The connecting block 502 is located inside the intersection of the two sets of second linkages 5042 and is fixedly connected to the inner end of the corresponding hinged shaft. The cross frame 503 has a hollow cuboid structure, and two first through slots 5031 and two second through slots 5032 are opened along the length of the cross frame 503. The two first through slots 5031 are symmetrically opened at both ends of the cross frame 503, and the two second through slots 5032 are located between the two first through slots 5031. The two second through slots 5032 are symmetrically opened on the outer wall of the cross frame 503 with the middle part of the cross frame 503 as the axis. The connecting assembly 506 includes a connector 5061 located at one end inside the crossbeam 503. Both ends of the connector 5061 are fixedly connected to a shaft 5062. One shaft 5062 is located in the first through groove 5031 and is fixedly connected to the movable seat 505. The other shaft 5062 is located in the second through groove 5032 and is hinged to the lower end of the second connecting rod 5042.

[0024] In this embodiment: when a designated material box needs to be delivered, the drone 1 is controlled to fly directly under the logistics box and slowly descend until the drone 1 is lowered to the ground and the material box is positioned between the two clamping plates 507. Alternatively, the drone 1 is lowered to a designated area and the material box is manually pushed under the drone 1 and positioned between the two clamping plates 507. Then, the drone 1 can be controlled to take off and ascend. During this process, the linkage assembly 504 will be stretched by the upward force of the drone 1. At the same time, the lower end of the second linkage 5042 will move towards the middle of the crossbar 503. The second linkage 5042 will also pull the movable seat 505 towards the middle of the crossbar 503 through the connecting assembly 506 until the two clamping plates 507 are respectively attached to the outer walls of both ends of the material box. Then, as the drone 1 gradually rises, the friction between the clamping plates 507 and the outer wall of the logistics box will be used to clamp and fly the material box. Once the delivery flight reaches the designated area, the drone 1 will land on the ground. During the descent of the drone 1, the clamping mechanism 5 and the logistics box will contact the ground first relative to the bottom of the logistics box, thereby releasing the friction between the clamping plate 507 and the logistics box. As the drone 1 lands smoothly, the connecting rod assembly 504 will also fold and retract, causing the lower end of the second connecting rod 5042 to move outward, thereby forcing both movable seats 505 to move outward, releasing the clamping force of the two clamping plates 507 on the logistics box.

[0025] Please refer to this carefully. Figures 1 to 8 The adsorption assembly 508 includes an electromagnet 5081 mounted on the bottom of the mounting base 501 and an iron block 5082 fixedly connected to the top of the connecting block 502, with the iron block 5082 located directly below the electromagnet 5081.

[0026] In this embodiment: During the stretching or folding / retracting process of the linkage assembly 504, the adsorption assembly 508 plays a key role. For example, when the drone 1 lands to unload, to prevent the drone 1 from clamping the logistics box again when taking off or moving, the electromagnet 5081 can be turned on, so that the electromagnet 5081 has magnetic attraction. When the linkage assembly 504 is folded and retracted, the electromagnet 5081 will contact and adsorb with the iron block 5082. Thus, when the drone 1 takes off again, the clamping plate 507 will no longer be forced to clamp the material box. Similarly, when the clamping plate 507 needs to clamp the material box, the electromagnet 5081 can be turned off, so that it loses its magnetic attraction. Thus, when the drone 1 takes off, the linkage assembly 504 will be stretched due to the gravity at the lower end, forming a clamping effect on the logistics box. It should be noted that the electromagnet 5081 in this solution is a commonly used electromagnet that can be powered by the internal battery of the drone. Its opening and closing control are all conventional system settings, which will not be elaborated on here.

[0027] Please refer to this carefully. Figures 1 to 8Both ends of the clamping plate 507 are integrally formed with connecting plates 5071. The connecting plates 5071 have an L-shaped structure. The distance between the inner walls of the two connecting plates 5071 is greater than the length of the cuboid material box. Rubber pads 5072 are adhered to the inner walls of the clamping plate 507 and the two connecting plates 5071.

[0028] In this embodiment: Since the left and right ends of the logistics box are clamped by two clamping plates 507 and there is no limiting structure at the front and rear, this solution adds connecting plates 5071 to the front and rear ends of the clamping plates 507 to limit the risk of the logistics box shifting forward and backward during transportation, which greatly improves safety. In addition, in order to improve the clamping stability and prevent excessive clamping force during the clamping process, this solution attaches rubber pads 5072 to the inner walls of the clamping plates 507 and connecting plates 5071, which can effectively ensure stable clamping and avoid hard damage to the logistics box.

[0029] Please refer to this carefully. Figures 1 to 8 The support leg assembly 3 includes a rectangular frame-like support leg frame 301. Two connecting columns 302 are symmetrically arranged on the upper inner side wall of the support leg frame 301. The lower end of the shock absorber 4 is hinged to the connecting column 302. Two rollers 303 are symmetrically sleeved at the bottom of the support leg 301, and the rollers 303 are located below the fixed plate 304; A magnet 5073 is embedded on the back of the connecting plate 5071. The outer walls of the support leg 301 are symmetrically provided with docking grooves 305 that match the width of the connecting plate 5071. When the support leg 301 is perpendicular to the ground, the docking grooves 305 contact the magnet 5073. The support leg 301 is made of iron.

[0030] In this embodiment: when the drone 1 lands, the roller 303 first contacts the ground, and then the lower end of the support leg 301 is forced to move outward under the gravity of the drone 1 and the logistics box. During the movement, the roller 303 rolls on the ground, which can effectively ensure the smooth movement of the lower end of the support leg 301. During the outward movement of the support leg 301, it will be affected by the shock absorber 4, thus forming a slow outward movement, which effectively reduces the impact force when the drone 1 lands on the ground. When the drone 1 needs to hold the logistics box during flight, as the drone 1 moves upward, the support leg 301, under its own weight and the spring return force on the shock absorber 4, will force the lower end of the support leg 301 to move inward until the support leg 301 is relatively perpendicular to the ground. At the same time, the docking slot 305 will dock with the magnet 5073, and the two sets of magnetic attraction will be connected. The fixing plate 304 will also be displaced to the bottom of the logistics box, which can be used to lift the bottom of the material box, further improving the stability of the logistics box during flight and effectively preventing the risk of the clamping plate 507 and the logistics box from sliding relative to each other and falling off.

[0031] It should be noted that the roller 303 in this solution mainly includes an annular roller. The annular roller is rotatably connected to the lower outer wall of the support leg frame 301 through a bearing. The crossbar at the lower end of the support leg frame 301 is fixed to the lower end of the support leg frame 301 by welding. The roller 303 is installed on the crossbar at the lower end of the support leg frame 301 before welding and fixing.

[0032] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
