Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to a logistics transportation UAV. Background Art

[0002] Currently, with the development of drone technology, drones are widely used in various industries. In mountainous and pastoral areas with underdeveloped transportation, agricultural and animal husbandry products cannot be delivered in a timely manner due to the influence of terrain, resulting in a waste of resources.

DETAILED DESCRIPTION

[0028] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0029] In addition, in the present invention, descriptions such as "first" and "second" are only used for descriptive purposes, and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions and technical features between the various embodiments can be combined with each other, but this must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0030] The present invention provides the following embodiments

[0031] Example 1: The present invention provides a logistics transport drone, such as Figure 1-Figure 2 As shown, it includes a drone shell 1, and a plurality of power mechanisms are arranged around the outer circumference of the drone shell 1. A cargo hold 23 is provided at the lower end of the drone shell 1. A fixing mechanism and an adsorption mechanism are installed in the cargo hold 23. Both the adsorption mechanism and the fixing mechanism are used to fix the cargo logistics box, and both the adsorption mechanism and the fixing mechanism are connected to a driving mechanism, which is connected to a balancing leg mechanism.

[0032] The power mechanism includes a support plate 3, which is fixedly connected to the upper side of the drone housing 1, and the support plate 3 is fixedly connected to the protective ring 2. The protective ring 2 is provided with a drone blade 4, and the drone blade 4 is rotatably connected to the support plate 3 through the motor shaft, and the drone blade 4 is fixedly connected to the power motor 24 through the motor shaft, and the power motor 24 is fixedly set on the support plate 3.

[0033] The working principle of the above technical solution is:

[0034] The power mechanism serves as a flight module. When the power motor 24 is working, it can drive the drone blades 4 to rotate, and can drive the logistics transport drone of the present invention and the fixed cargo logistics box to fly and move. The setting of the protective ring 2 protects the drone blades 4 to prevent the drone blades 4 from being damaged by external interference. The cargo warehouse 23 is used to accommodate the cargo logistics box, protect the cargo logistics box, and reduce the impact of the external environment on the cargo logistics box. When the driving mechanism is working, it can drive the fixing mechanism, the adsorption mechanism and the balancing leg mechanism to work. When the cargo logistics box is fixed, the balancing leg mechanism gradually moves downward, so that the lower end surface of the fixed cargo logistics box is higher than the lower end surface of the balancing leg mechanism. In the falling process of the logistics transport drone of the present invention driving the cargo logistics box to move to the unloading position, the balancing leg mechanism can first contact the unloading position to avoid the impact force if the cargo logistics box first contacts the unloading position during the falling process of the logistics transport drone. If the cargo box is too large, it will easily cause damage to the cargo logistics box and the logistics transport drone of the present invention. The setting of the fixing mechanism can clamp and fix the cargo logistics box, and the setting of the adsorption mechanism can adsorb and connect the cargo logistics box. Through the joint action of the fixing mechanism and the adsorption mechanism, compared with only using the fixing mechanism to clamp and fix the cargo, the connection and fixing effect of the logistics transport drone of the present invention on the cargo can be improved, and there is no need to manually tie and fix the cargo logistics box, which saves time and effort, and solves the problem that logistics transport drones generally use nylon belts or relatively stable ligaments to tie and fix the cargo transport box, which not only requires manual operation and consumes a lot of manpower, resulting in a waste of transportation time, but also easily causes the cargo transport box to fall off if the binding is not firm. When the clamping mechanism is used to automatically clamp and fix the logistics transport box, the drone will cause bumps in the event of uneven flight during flight, which easily causes the cargo to fall loose.

[0035] Example 2: Based on Example 1, Figures 1-4 As shown, the driving mechanism includes sliding grooves 9 symmetrically arranged on the front and back sides of the left and right ends of the drone housing 1, and an electric telescopic rod 27 is fixedly installed in the sliding groove 9, and the electric telescopic rod 27 is fixedly connected to the sliding seat 10;

[0036] The balancing leg mechanism includes a sliding seat 10 slidably arranged in the sliding slot 9. The sliding seat 10 is provided with an open slot 1 at one end away from the drone housing 1. A drive shaft 1 54 is rotatably provided in the open slot 1. The drive shaft 1 54 passes through the side end of the open slot 1 and is fixedly connected to the motor 11. The motor 11 is fixedly connected to the sliding seat 10. The drive shaft 1 54 is fixedly connected to the elastic rod 8. The elastic rod 8 is rotatably connected to the drive shaft 2 40 in the open slot 26. The drive shaft 2 40 is rotatably arranged in the open slot 26. The open slot 26 is provided at the upper end of the support seat 7.

[0037] The lower end of the sliding seat 10 is fixedly connected to the connecting block 16, the connecting block 16 is fixedly connected to the protective cover 5, and the protective cover 5 is slidably connected to the annular groove at the lower end of the drone housing 1;

[0038] The balancing leg mechanism also includes rotating blocks 15 respectively arranged on the side ends of the four sides of the drone shell 1. The lower end of the rotating block 15 is fixedly connected to the counterweight block 17 through a connecting block 2 16. The counterweight block 17 is respectively provided with a control arc block 18 on the side close to the sliding groove 9. The control arc block 18 is installed in the open groove at the side end of the drone shell 1, and a spring 1 is fixed between the control arc block 18 and the open groove. A control switch is installed in the open groove. The control switch is set corresponding to the control arc block 18. The control switch is electrically connected to the motor 11 close to the side of the control arc block 18 through a controller 1.

[0039] The working principle of the above technical solution is:

[0040] When the electric telescopic rod 27 is extended or retracted, it can drive the sliding seat 10 to slide along the sliding groove 9. When the sliding seat 10 moves up and down along the sliding groove 9, it can drive the driving shaft 1 54 to move up and down. The driving shaft 1 54 drives the elastic rod 8 and the driving shaft 2 40 connected thereto to move up and down. The driving shaft 2 40 drives the supporting seat 7 to move up and down. The supporting seat 7 is made of elastic shock-absorbing material. The supporting seat 7 is used to contact the contact surface of the unloading position. The setting of the elastic rod 8 and the supporting seat 7 can absorb the impact force of the logistics transport drone of the present invention when it lands, and has the effect of buffering and shock absorption. When the sliding seat 10 moves downward, it can drive the protective cover 5 to move downward. The protective cover 5 can cover the cargo logistics box to reduce the external impact on the cargo logistics box. The influence of the environment plays a protective role. The setting of the counterweight block 17, under the action of the gravity of the counterweight block 17, drives the connecting block 2 16 to be unable to rotate with the tilt of the drone shell 1. When the logistics transport drone of the present invention falls to the working position and is in a tilted state, the drone shell 1 and the rotating block 15 rotate relative to each other, and the center of the rotating block 15 coincides with the center of the control arc block 18. During this process, the counterweight block 17 will contact the control arc block 18, and the end of the control arc block 18 close to the counterweight block 17 is set as an inclined section, so that the control arc block 18 can contact the counterweight block 17, and after the counterweight block 17 contacts the control arc block 18, it can push the control arc block 18 into the open groove and align with the control arc block 18. The switch contacts, the spring is compressed, and after the control switch contacts the control arc block 18, the controller controls the motor 11 adjacent to the control arc block 18 to work. Each motor 11 is adjacent to two control arc blocks 18, that is, any one of the two control arc blocks 18 can control the motor 11 adjacent to it to work after entering its corresponding opening slot. The motor 11 drives the drive shaft 54 ​​to rotate, and the drive shaft 54 ​​drives the elastic rod 8 and the support seat 7 connected thereto to move toward the direction of the drone shell 1, pushing the drone shell 1 at this angle, so that the drone shell 1 moves toward the horizontal state until the logistics transport drone of the present invention returns to a horizontal state. At the drone shell 1 When in a horizontal state, the counterweight block 17 is disengaged from the control arc block 18, and the control arc block 18 returns to its original position under the elastic action of spring 1. At this time, the contact switch can no longer control the operation of the adjacent motor 11, and the motor 11 stops working. At this time, the cargo logistics box in the cargo warehouse 23 remains horizontal, which is convenient for unloading the cargo logistics box. When the cargo logistics box is not transported, the operation of the motor 11 and the electric telescopic rod 27 can increase the fitting area between the elastic rod 8 and the drone shell 1, thereby reducing the wind resistance of the logistics transport drone of the present invention and reducing energy consumption. The motor 11 does not work during the flight of the drone to avoid the drone tilting during flight, which causes the motor 11 to work and increase the loss of electrical energy.

[0041] Example 3: Based on Example 2, Figure 2 、 Figure 5-Figure 8As shown, the fixing mechanism includes a fixing plate 21 symmetrically arranged on the left and right sides of the cargo bin 23, and the fixing plate 21 is slidably arranged between the front and rear ends of the cargo bin 23, and a plurality of distance sensors 22 are evenly spaced along the front-to-back direction at the middle part of the end of the fixing plate 21 that is close to each other, and the plurality of distance sensors 22 are electrically connected to the drone control device through the second controller, and a plurality of elastic blocks 46 are evenly spaced along the front-to-back direction on the upper side of the end of the fixing plate 21 that is away from each other, and the plurality of elastic blocks 46 are fixedly connected to the mounting plate 1 34, and a plurality of mounting blocks 35 are evenly spaced along the front-to-back direction at the end of the mounting plate 1 34 that is away from the elastic block 46, and the mounting block 1 35 is rotatably connected to the guide wheel 36, and the guide wheel 36 is in corresponding contact with the inclined end of the fixing block 25, and the fixing block 25 is fixedly connected to the sliding seat 10 near one side thereof;

[0042] A contact block 55 is provided on the lower side of one end of the fixed blocks 25 that is close to each other for sliding. A rack 1 is provided on the lower end of the contact block 55 near the side of the mounting plate 1 34. The front and rear sides of the rack 1 are respectively meshed with gears 30. The gears 30 on the front and rear sides are respectively arranged on the front and rear sides of the mounting shaft 29. The front and rear ends of the mounting shaft 29 are symmetrically provided with mounting plates 28. The mounting plate 28 is fixedly connected to one end of the fixed plate 21 near the mounting plate 1 34. A torsion spring 45 is fixedly provided between the mounting plate 28 and the gear 30. The torsion spring 45 is sleeved on the mounting shaft 29. The gear 30 is meshed with the rack 2. The rack 2 is fixedly connected to the upper end of the mounting plate 31. The mounting plate 31 is fixedly connected to the block 32 through a number of spring rods 33. The block 32 is slidably connected to the lower end of the fixed plate 21.

[0043] The working principle of the above technical solution is:

[0044] When fixing the cargo logistics box, first control the logistics transport drone of the present invention to fly to the corresponding position of the cargo logistics box, so that the cargo logistics box enters the cargo warehouse 23. At this time, the cargo logistics box is located between the fixed plates 21 on the left and right sides. The several distance sensors 22 set on the fixed plates 21 are used to detect the distance between the fixed plates 21 and the cargo logistics box. The drone control device adopts the existing drone remote control, which can display the detection values ​​of several distance sensors 22. The several distance sensors 22 set on the same fixed plate 21 are used to detect whether the fixed plate 21 is parallel to the side end of the cargo logistics box. If the detection values ​​of the several distance sensors set on the same fixed plate 21 are the same, it means that the fixed plate 21 and the cargo logistics box are parallel. The side ends of the box remain parallel, and when the detection values ​​of the distance sensors set on the fixed plates 21 on the left and right sides are the same, it means that the distances between the fixed plates 21 on the left and right sides and the cargo logistics box are the same. At this time, the electric telescopic rod 27 is controlled to work. When the electric telescopic rod 27 is retracted, the fixed block 25 can be driven to move downward through the sliding seat 10. The inclined section of the fixed block 25 contacts the guide wheel 36, and the mounting plate 34 can be driven to move toward the fixed plate 21 through the guide wheel 36 and the mounting block 35, so that the fixed plates 21 move in the direction of approaching each other until the fixed plates 21 clamp the cargo logistics box. At this time, the detection values ​​of the distance sensors set on the fixed plates 21 are all 0, and the setting of the elastic block 46 makes the fixed plate 21 The fixed plate 21 has a buffering effect on the clamping process of the cargo logistics box, avoiding the fixed plate 21 from directly and rigidly contacting the cargo logistics box, causing squeezing damage to the cargo logistics box, and reducing the vibration and collision between the cargo logistics box and the fixed plate 21 during transportation. When the fixed plate 21 moves in the direction of approaching each other, it first drives the contact block 55 to contact the cargo logistics box, and the contact block 55 slides along the fixed plate 21. During this process, the contact block 55 drives the rack 1 to move, and the rack 1 drives the gear 30 to rotate. During the rotation of the gear 30, it drives the rack 2 to move, and the rack 2 drives the mounting plate 31 to move. The mounting plate 31 drives the block 32 to move through the spring rod 33, and the block 32 slides along the lower end of the fixed plate 21. The lower end surface of the flow box should be higher than the upper end surface of the block 32, that is, the height of the fixed plate 21 is greater than the height of the cargo logistics box. The block 32 will move to the corresponding position of the lower end of the cargo logistics box to prevent the cargo logistics box from falling. If the block 32 contacts the support area at the lower end of the cargo logistics box during the clamping and fixing of the cargo logistics box, the block 32 will drive the spring rod 33 to compress until the logistics transport drone of the present invention drives the cargo logistics box out of its support area. Under the elastic action of the spring rod 33, the block 32 continues to move to the corresponding position at the lower end of the cargo logistics box. The size of the support area selected when placing the cargo logistics box should be smaller than the size of the cargo logistics box to avoid affecting the clamping and fixation of the cargo logistics box by the fixed plate 21.

The driving block 14 passes through the upper end of the drone shell 1 and enters the cargo compartment 23 and is fixedly connected to the upper end of the fixing block 25.

[0046] The front and rear ends of the support hinge shaft 41 are symmetrically provided with movable blocks 42, which are slidably connected to the open groove 48 at the upper end of the fixed sleeve 43.

[0048] By arranging a suction cup 19 on the upper side of the cargo warehouse 23, when the logistics transport drone of the present invention flies to the corresponding position of the cargo logistics box and the cargo logistics box enters the cargo warehouse 23, after the upper end of the cargo logistics box contacts the suction cup 19 in the cargo warehouse 23, the logistics transport drone of the present invention is controlled to stop flying. The suction cup 19 is made of rubber material, so the contact process between the cargo warehouse 23 and the cargo logistics box is flexible contact. At this time, it is equivalent to the drone shell 1 being placed on the cargo logistics box, thereby ensuring that the lower end of the fixed plate 21 is lower than the lower end of the cargo logistics box, ensuring the clamping effect of the fixed plate 21 on the cargo logistics box, and in the process of moving the fixed block 25, it will also drive the driving block 14 to move downward, and the driving block 14 drives the support plate 1 38 to rotate through the connecting shaft 2 52, and the support plate 1 38 drives the slider 37 to slide along the upper end of the sealing push plate 13 through the connecting shaft 1 53, and in this process drives the sealing push plate 13 along the power The interior of the energy shell 12 slides upward, so that the space connecting the interior of the functional shell 12 and the suction cup 19 becomes larger, and the air pressure inside the suction cup 19 becomes smaller. At the same time, since the support plate 1 38 drives the slider 37 to move in the direction of moving away from each other, the distance between the left and right support plates 1 38 gradually increases, thereby causing the left and right support plates 2 39 to rotate in the direction of approaching each other, and the support plate 2 39 drives the support hinge shaft 41 to move downward, and the support hinge shaft 41 drives the mounting block 2 50 to move downward. The setting of the bellows 51 can enable the suction cup 19 to move freely, so that the mounting block 2 50 drives the suction cup 19 to squeeze and contact the cargo logistics box, so that the interior of the suction cup 19 is in a sealed state, completing the adsorption connection to the cargo logistics box, and the mounting block 2 50 is set as an elastic block. Even if the mounting block 2 50 cannot drive the suction cup 19 to continue to move downward, the mounting block 2 50 can be deformed, thereby ensuring the normal movement of the fixed block 25;

[0049] When the support hinge shaft 41 moves downward, it also drives the movable block 42 to slide toward the open groove 48. During this process, the matching block 47 enters the groove, and the spring three is compressed, so that the matching block 47 also enters the open groove 48. Due to the setting of the mounting block 2 50 and the elastic block 46, it can be ensured that the fixed block 25 can continue to move downward after the suction cup 19 and the fixed plate 21 contact the cargo logistics box, thereby ensuring that the matching block 47 can move to the position of the working port 49. At this time, the electric telescopic rod 27 should be controlled to stop working. If the drone shell 1 is in a tilted state, at this time, due to the gravity of the counterweight block 17, the connecting block 2 16 cannot move with the drone shell 1 is tilted and rotated, so the working arc block 44 remains stationary. As the drone shell 1 tilts, the fixed sleeve 43 rotates. At this time, the working opening 49 on one side of the fixed sleeve 43 is inserted into the working arc block 44 on the corresponding side, and the working opening 49 on the other side is away from the working arc block 44 on the other side. At this time, under the elastic action of spring three, the matching block 47 can extend out of the working opening 49, and the matching block 47 plays a limiting role. The movable block 42 can continue to move toward the direction of the opening slot 48 and cannot move in the direction away from the opening slot 48, thereby ensuring the adsorption connection between the suction cup 19 and the cargo logistics box, thereby avoiding the movable block 42 corresponding to the The connected fixed block 25 moves upward. When the fixed block 25 moves upward, the suction cup 19 will be separated from the adsorption connection to the cargo logistics box and the clamping and fixing of the cargo logistics box by the fixed plate 21. Therefore, when the matching block 47 moves to the corresponding position of the working port 49, the fixed block 25 cannot move upward. The flight direction of the logistics transport drone of the present invention is the opening direction of the working port 49 on the fixed sleeve 43, so that when the logistics transport drone of the present invention is in a tilted state during flight, the fixed block 25 is in a locked state, ensuring that the suction cup 19 is always adsorbed and connected to the cargo logistics box, and the fixed plate 21 is always clamped and fixed to the cargo logistics box, avoiding The tilting state of the logistics transport drone causes the center of gravity of the cargo logistics box to change, which in turn affects the connection effect between the cargo logistics box and the logistics transport drone. If the logistics transport drone maintains a horizontal state, the working arc blocks 44 distributed on the left and right correspond to the working openings 49 on the left and right sides. At this time, the matching block 47 cannot extend out of the working opening 49. The electric telescopic rod 27 can drive the fixed block 25 to move upward to complete the normal unloading steps. During unloading, the elastic rod 8 and the drive shaft 2 40 and the support seat 7 connected thereto gradually shrink upward, which can reduce the height between the cargo logistics box and the unloading position, and reduce the impact force on the cargo logistics box during unloading.

[0050] The adsorption mechanism and fixing mechanism of the present invention can automatically and synchronously complete the adsorption and clamping steps through the operation of the electric telescopic rod 27 in the driving mechanism. There is no need to set up multiple electrical components to separately drive the adsorption and clamping steps. While facilitating the operation of the drone control personnel, it saves energy consumption of the logistics transport drone of the present invention and improves its endurance.

[0051] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
