Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle equipment, and particularly to a logistics unmanned aerial vehicle. Background Art

[0002] A logistics unmanned aerial vehicle is a new type of transportation tool based on intelligent navigation and autonomous control technologies. Through its efficient and precise aerial delivery capabilities, it realizes the delivery of supplies to remote areas, instant delivery at the urban end, and the scheduling of emergency relief supplies, significantly reducing transportation costs and breaking through terrain and traffic restrictions, thus promoting the intelligent upgrading of the logistics industry.

[0003] However, the following deficiencies exist in the prior art: Currently, logistics unmanned aerial vehicles mainly park and load logistics express items in open spaces within logistics parks. As a result, the existing logistics express items need to be transported to the surrounding areas of the open space for sorting, and then the loading of the unmanned aerial vehicle express items is completed. This leads to the situation that the existing logistics unmanned aerial vehicles cannot enter the logistics warehouse to complete the loading work of logistics express items. Summary of the Invention

[0004] Other features and advantages of the present invention will be described in the following specification, and will become partially apparent from the specification, or can be understood by implementing the present invention. The objectives and other advantages of the present invention can be achieved and obtained through the structures specifically pointed out in the specification and other accompanying drawings of the specification.

[0005] The objective of the present invention is to overcome the above deficiencies, and provide a logistics unmanned aerial vehicle that can be triggered to move forward by a traveling drive member on a logistics loading mobile box connected below the unmanned aerial vehicle, enabling the unmanned aerial vehicle to directly enter the logistics park warehouse to load logistics express items. This avoids the need to set up open spaces within the park and also eliminates the need to transport the logistics express items to an open space for loading, allowing the unmanned aerial vehicle to directly enter the logistics warehouse and complete the express item loading work within the warehouse.

[0006] To achieve the above object, the present invention is realized through the following technical solutions: A logistics drone, including a drone, a logistics loading and moving box is installed below the drone, a box body is arranged inside the logistics loading and moving box, expansion batteries are arranged on both sides of the box body, an even number of installation slots are arranged below the box body, an even number of walking driving parts are installed in the installation slots, a distribution box is installed at one end of the box body, an inner concave equipment slot is arranged between the installation slots, two of the walking driving parts face inwards, and one of the walking driving parts faces outwards. The walking driving part facing outwards and the walking driving part facing inwards form a triangular state; a first torsion drive is arranged inside the walking driving part, a second torsion drive is installed below the first torsion drive, a connecting frame is fixed on the second torsion drive, wing swing rods are arranged on both sides of the second torsion drive, a swinging walking foot is connected between the wing swing rods, and an arc-shaped limiting slot is opened on the side wall of the connecting frame; an even number of bearing frames are arranged in the inner concave equipment slot, drive battery packs are installed on the bearing frames, a controller is arranged beside the drive battery packs, and a partition lock plate covers the drive battery packs and the controller. The first torsion drive is mainly used for direction regulation, while the second torsion drive cooperates with the swinging walking foot to form walking, and then drives the drone above the box body to directly go to the express loading area in the logistics warehouse to complete the express loading work.

[0007] For further improvement of the present invention, an upper connecting sleeve is installed on the upper surface of the second torsion drive, a driving outer connecting shaft is installed on one side of the second torsion drive, a secondary connecting shaft is arranged on the other side of the second torsion drive, a walking foot shell is arranged inside the swinging walking foot, an internal torsion drive is installed inside the walking foot shell, heat dissipation slots are opened on the outer surface of the walking foot shell, a rubber sleeve frame is connected below the walking foot shell, and a contact ground foot penetrates through and is connected to the center of the rubber sleeve frame. The internal torsion drive is mainly used to drive the walking foot shell to walk in a human-like manner, and then swing the shaft foot shell to complete forward movement in a fixed direction.

[0008] For further improvement of the present invention, the partition lock plate is used for separating and limiting the controller and the drive battery packs. The partition lock plate is locked with the inner wall of the inner concave equipment slot, and the controller and the drive battery packs are electrically matched with the walking driving parts. The drive battery packs mainly supply power to the independent walking driving parts respectively, while the controller is externally connected to the terminal for program control to make it complete the walking work, and the power supply system of the walking driving parts and the drone are used independently and separately.

[0009] For further improvement of the present invention, the upper part of the ground contact foot is connected into the inside of the walking foot shell. The heat dissipation groove is used for the heat dissipation of the built-in torsion drive. Among the even-numbered side wing swing rods, there are long swing rods and short swing rods. The built-in torsion drive is fixed to the short swing rod among the side wing swing rods. The other side of the walking foot shell is fixed to the long swing rod among the side wing swing rods through a shaft rod. The bottom of the ground contact foot is provided with tooth-shaped anti-slip stripes. The tooth-shaped anti-slip stripes on the bottom surface of the ground contact foot mainly better form friction with the ground, thereby enhancing the grip during walking and avoiding slipping during walking.

[0010] For further improvement of the present invention, the upper connecting sleeve is connected to the first torsion drive and can be adjusted in angle. The drive outer connecting shaft is connected and fixed to the long swing rod among the side wing swing rods. The auxiliary connecting shaft is fixed to the short swing rod among the side wing swing rods. The long swing rod among the side wing swing rods passes through the arc-shaped limiting groove through a convex shaft and is movably matched with it. The first torsion drive is installed in the installation groove. The long swing rod on the side wing swing rod mainly swings back and forth through the convex shaft in the limiting groove, driving the walking foot shell to repeatedly adjust up and down, imitating the humanoid "knee-lifting" state.

[0011] For further improvement of the present invention, a load-carrying closing frame is installed at one end of the box body. The outer wall of the load-carrying closing frame is fixed with a box door drive. A locked closing door is installed on the box door drive. A load-carrying cavity is arranged behind the locked closing door. A load-carrying platform is installed in the load-carrying cavity. An even number of auxiliary conveying supports are installed on the inner wall of the load-carrying cavity. The lock body on the locked closing door is mainly used for inputting the pick-up code, so as to judge the identity of the logistics express delivery extractor and avoid the loss of logistics express deliveries.

[0012] For further improvement of the present invention, a fixed block is arranged in the load-carrying platform. An even number of electric control push rods are installed on the fixed block. The top ends of the electric control push rods are connected to a lower support platform. An upper loading rack is installed above the lower support platform. An even number of on-platform roller rows are installed on the lower support platform. A sleeve spring block is arranged in the auxiliary conveying support. A slideway is opened on the sleeve spring block. An inner top spring is nested in the sleeve spring block. A two-way auxiliary support wheel is installed on the slideway. The lower support platform can mainly be pushed outwards through the electric control push rods, and the upper loading rack arranged above slides down after the lower support platform tilts, extending out of the load-carrying cavity, facilitating the extraction of logistics express deliveries by the pick-up person.

[0013] For further improvement of the present invention, the bidirectional auxiliary support wheel is supported by the inner top spring, the slideway is in an arc state, the bidirectional auxiliary support wheel is slidably matched with the lower support table, the fixed block is fixed in the load cavity, the electric control push rod can push the lower support table outwards, the lower surface of the upper loading rack is slidably matched with the roller row on the table, and the groove on the inner convex block of the lower support table forms a limit engagement with the outer convex block of the upper loading rack. The bidirectional auxiliary support wheel is mainly jacked up to the top of the slideway with the assistance of the inner top spring and provides auxiliary support when the lower support table is horizontal. As the lower support table is pushed outwards and stressed, it slides down on the slideway accordingly to assist the lower support table to be in an inclined state.

[0014] For further improvement of the present invention, a monitor is installed in front of the drone, a power supply hole is installed behind the drone, an even number of folding drive wings are installed on the drone, a collision prevention frame covers the folding drive wings, an even number of connecting seats are installed on the upper surface of the drone, a fixed ring frame is installed on the lower surface of the drone, an even number of connecting rods are installed on the lower surface of the fixed ring frame, a stable seat is arranged inside the collision prevention frame, a pressing cap is connected above the stable seat, a sickle-shaped rod is connected to the stable seat, an arched rod is connected to the middle position of the sickle-shaped rod, arc-shaped frames are connected to the ends of the sickle-shaped rod and the arched rod, and an axle support groove is formed in the stable seat. The pressing cap mainly plays a role in connecting with the stable seat and completes the top fixation of the sickle-shaped rod through the pressing cap to make it in a suspended state, and cooperates with the arched rod and the arc-shaped frame to cover the paddle wings in the folding drive wings.

[0015] For further improvement of the present invention, the axle support groove is connected to the end of the sickle-shaped rod. The sickle-shaped rod, the arched rod and the arc-shaped frame together cover the folding drive wings. The sickle-shaped rod, the arched rod and the arc-shaped frame together form a "hat" shape, and a protective net can be covered on the "hat" shape. The stable seat is connected to the connecting seat, and the power supply hole is connected to the distribution box through a wire harness. The shaft rod in the axle support groove is nested and connected to the end of the sickle-shaped rod, so that the sickle-shaped rod can swing after the pressing cap is taken off, which is convenient for the subsequent maintenance of the paddle wings on the folding drive wings.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. After the walking drive member on the logistics loading and moving box hung under the drone triggers the second torsion drive and the swinging walking feet when the drone returns to the connection position of the logistics park warehouse, and stops the folding drive wings, relying on the assistance of the swinging walking feet to drive the box body and the drone above into the logistics warehouse, thereby avoiding the setting of open spaces in the park and eliminating the need to transport the logistics express to an open space for loading the logistics express, realizing that the drone directly enters the logistics warehouse and directly completes the express loading work in the warehouse.

[0017] 2. The present invention closes the load-carrying closing frame through a lockable closing door, thereby ensuring the safety of the logistics express on the loading platform during flight. At the same time, after the flight reaches the designated area, the verification pick-up code on the lockable closing door is used to open the door body. Then, under the outward movement of the lower support platform, the upper loading rack above is also displaced out of the loading cavity together, facilitating the extraction of the logistics express and the loading work of the logistics express in the early stage.

[0024] The following further describes the present invention with reference to the accompanying drawings: Embodiment 1

[0025] As shown in the Figure 1 to Figure 6 accompanying drawings: This embodiment provides a logistics drone, which includes a drone 1. A logistics loading and moving box 2 is installed below the drone 1. A monitor 11 is installed in front of the drone 1. A power socket 12 is installed behind the drone 1. An even number of folding drive wings 15 are installed on the drone 1. An anti-collision frame 14 covers the folding drive wings 15. An even number of connecting seats 13 are installed on the upper surface of the drone 1. A fixed ring frame 16 is installed on the lower surface of the drone 1. An even number of connecting rods 17 are installed on the lower surface of the fixed ring frame 16. A box body 21 is arranged inside the logistics loading and moving box 2. Expansion batteries 22 are arranged on both sides of the box body 21. An even number of installation slots 23 are arranged below the box body 21. An even number of walking drive components 25 are installed in the installation slots 23. A distribution box 24 is installed at one end of the box body 21. An inner concave equipment slot 26 is arranged between the installation slots 23. Two of the walking drive components 25 face inwards, and one of the walking drive components 25 faces outwards. The walking drive component 25 facing outwards and the walking drive components 25 facing inwards form a triangular state; A first torsion drive 251 is arranged inside the walking drive component 25. A second torsion drive 252 is installed below the first torsion drive 251. A connecting frame 253 is fixed on the second torsion drive 252. Flanking swing rods 254 are arranged on both sides of the second torsion drive 252. A swinging foot 255 is connected between the flanking swing rods 254; An even number of bearing frames 261 are arranged inside the inner concave equipment slot 26. A drive battery pack 263 is installed on the bearing frame 261. A controller 264 is arranged beside the drive battery pack 263. A partition lock plate 262 covers the drive battery pack 263 and the controller 264. An upper connecting sleeve 2522 is installed on the upper surface of the second torsion drive 252. A drive outer connecting shaft 2521 is installed on one side of the second torsion drive 252. A secondary connecting shaft 2523 is arranged on the other side of the second torsion drive 252. An arc-shaped limiting groove 2531 is formed on the side wall of the connecting frame 253. A foot housing 2551 is arranged inside the swinging foot 255. An internal torsion drive 2552 is installed inside the foot housing 2551. Heat dissipation grooves 2553 are formed on the outer surface of the foot housing 2551. A rubber sleeve frame 2554 is connected below the foot housing 2551. A contact foot 2555 penetrates and is connected to the center of the rubber sleeve frame 2554.

[0026] Further, the swinging foot 255 is fixed to the flanking swing rods 254 through the internal torsion drives 2552 on both sides, so that under the up-and-down swing cooperation of the flanking swing rods 254 and the drive of the internal torsion drive, the foot housing 2551 swings by itself to complete the movement.

[0027] Further, the second torsion drive 252 is mainly connected to the first torsion drive 251 through the upper connecting sleeve 2522 installed on the upper surface, and then the position offset of its movement is changed according to the angle adjustment of the first torsion drive 251.

[0028] Further, the arc-shaped limiting groove 2531 is mainly installed on one side of the connecting frame 253, forms a connection with the wing swing rod 254 in cooperation, and under the cooperation of the second torsional drive, limits the wing swing rod 254 to assist the wing swing rod 254 to complete the "knee-lifting" work during walking.

[0029] Further, the grounding foot 2555 is mainly connected to the inside of the walking foot shell 2551 after its connecting rod passes through the rubber sleeve frame 2554. The rubber sleeve frame 2554 is in the shape of an inverted isosceles trapezoid as a whole, and the impact force during the take-off and landing of the grounding foot 2555 can be buffered through its own colloid.

[0030] The specific working principle is as follows: In the present invention, the unmanned aerial vehicle 1 carries the logistics loading and moving box 2 suspended below for flight. After the logistics express is picked up, it directly returns to the warehouse in the logistics park and lands on the landing platform of the warehouse. The folding drive wing 15 is stopped. Then, the walking drive member 25 in the installation groove 23 below the box body 21 is powered by the independent drive battery pack 263 in the concave equipment groove 26. Under the program cooperation of the controller 264, the first torsional drive 251 is driven to complete the adjustment of the traveling angle. The second torsional drive 252 cooperates with the arc-shaped limiting groove 2531 on the connecting frame 253 to complete the repeated swinging of the wing swing rod 254, driving the walking foot shell 2551 between the wing swing rods 254 to lift. During the lifting process, the built-in torsional drive 2552 in the walking foot shell 2551 swings the walking foot shell 2551, thereby indirectly driving the grounding foot 2555 to move forward. Among them, the walking drive members 25 arranged in the middle group travel alternately, so that the unmanned aerial vehicle 1 together with the logistics loading and moving box 2 travels to the logistics warehouse to complete docking and perform subsequent reloading work of the logistics express. Embodiment 2

[0031] As shown in the attached Figure 7 to the attached Figure 9 figure: Among them, a load-carrying closing frame 211 is installed at one end of the box body 21. A box door drive 212 is fixed on the outer wall of the load-carrying closing frame 211. A locked closing door 213 is installed on the box door drive 212. A loading cavity 215 is arranged behind the locked closing door 213. A loading platform 214 is installed in the loading cavity 215. An even number of auxiliary conveying brackets 216 are installed on the inner wall of the loading cavity 215. A fixing block 2141 is arranged in the loading platform 214. An even number of electric control push rods 2142 are installed on the fixing block 2141. The top ends of the electric control push rods 2142 are connected to a lower supporting platform 2143. An upper loading frame 2144 is installed above the lower supporting platform 2143. An even number of on-platform roller rows 21431 are installed on the lower supporting platform 2143. A spring sleeve block 2161 is arranged in the auxiliary conveying bracket 216. A slideway 2162 is opened on the spring sleeve block 2161. An inner top spring 2163 is nested in the spring sleeve block 2161. A two-way auxiliary supporting wheel 2164 is installed on the slideway 2162.

[0032] Furthermore, at least two electric control push rods 2142 are provided. They are embedded and inclinedly installed through the fixing block 2141 so that the lower supporting platform 2143 can be pushed outwards and extended after the electric control push rods 2142 are triggered.

[0033] Furthermore, the lower supporting platform 2143 and the upper loading frame 2144 are in a nested and engaged manner. So that after the lower supporting platform 2143 is pushed and inclined by the electric control push rods 2142, the upper loading frame 2144 can slide outwards, facilitating the extension of the upper loading frame 2144 out of the loading cavity 215 for loading logistics express items.

[0034] Furthermore, the two-way auxiliary supporting wheel 2164 mainly plays a corresponding supporting role when the lower supporting platform 2143 is parallel. When the lower supporting platform 2143 is inclined, the center of gravity of the two-way auxiliary supporting wheel 2164 changes and slides down along the slideway 2162 to complete the auxiliary conveying work of the lower supporting platform 2143.

[0035] The specific working principle is as follows: In the present invention, the unmanned aerial vehicle 1 carries the box body 21 into the logistics warehouse together. When loading goods, the door drive 212 of the box triggers the locking and closing door 213 to open. Then, under the action of the electric control push rod 2142 on the fixed block 2141 of the loading platform 214 in the loading cavity 215, the lower support platform 2143 is lifted and pushed out. During the pushing process, the position of the lower support platform 2143 changes, changing the center of gravity of the double-direction auxiliary support wheel 2164. Along with this, the double-direction auxiliary support wheel 2164 displaces in the slideway 2162 and presses on the inner top spring 2163. After the lower support platform 2143 tilts, the upper loading frame 2144 slides due to the inclination to cooperate with the limit card slot of the lower support platform 2143 and the roller row 21431 at the bottom, expanding into the loading cavity 215, facilitating the direct placement of logistics express items in the upper loading frame 2144. When flying to the pick-up area, the pick-up person needs to input the pick-up code on the locking and closing door, and then trigger the door drive 212 to open the locking and closing door 213. Thus, the same steps as loading the logistics express items are followed. The electric control push rod 2142 pushes the lower support platform 2143 outwards, indirectly expanding the upper loading frame 2144 out of the loading cavity 215, facilitating the extraction of logistics express items. Embodiment 3

[0036] As shown in the Figure 10 appendix Among them, a stable seat 144 is arranged inside the anti-collision frame 14. A pressing cap 145 is connected above the stable seat 144. A sickle-shaped rod 142 is connected to the stable seat 144. An arched rod 143 is connected to the middle position of the sickle-shaped rod 142. Arc-shaped frames 141 are connected to the ends of the sickle-shaped rod 142 and the arched rod 143. A shaft support groove 1441 is formed on the stable seat 144.

[0037] Furthermore, the arc-shaped frame 141, the sickle-shaped rod 142, and the arched rod 143 are all made of hollow stainless steel and are connected by welding to form a "cap" shape to cover the propeller blade.

[0038] Furthermore, the shaft support groove 1441 is mainly formed on the stable seat 144. The sickle-shaped rod 142 is limited and supported through the cooperation of the shaft rod and the groove body. After the pressing cap 145 on the top is disconnected from the stable seat 144, the sickle-shaped rod 142 can swing, facilitating the maintenance of the covered propeller blade.

[0039] The specific working principle is as follows: In the present invention, the stabilizing base 144 is connected to the connecting base 13, and then the sickle-shaped rod 142 is connected and fixed at the shaft support groove 1441. After the sickle-shaped rod 142 is welded to the arched rod 143 and the arc-shaped frame 141 respectively, a protective net can be installed on the outer surface. Finally, the pressing cap 145 is connected and fixed to the stabilizing base 144, and the sickle-shaped rod 142 is top-fixed and supported, and is suspended outside the folding drive wing 15 to achieve wrapping, so as to avoid the collision damage of the folding drive wing when the drone enters the logistics warehouse.
