Detailed implementation manners

[0019] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1 - 19 shown, the conveying mechanism of the present invention includes a commutator 1, a connecting shaft 2, a transmission shaft 3, a transmission roller 4, a conveyor belt 5, and an actuator 6.

[0021] As Figures 1 - 5 shown, a plurality of commutators 1 are longitudinally arranged, and the commutators 1 are connected to each other by a connecting shaft 2; a transmission shaft 3 is provided on each commutator 1, and multiple transmission shafts 3 are parallel to each other; a plurality of transmission rollers 4 are sleeved on each transmission shaft 3, and the transmission rollers 4 are the power sources of the conveyor belt 5; In the above structure, the commutator 1 adopts a bevel gear commutator, and a plurality of commutators 1 are connected in series through a connecting shaft 2. Among them, the commutator 1 can be arranged in two columns and connected by a connecting shaft 2; when driving in this structure, one of the commutators 1 is connected to the main shaft of the motor, and all the commutators 1 can be driven. Among them, the transmission shaft 3 is connected to the commutator 1, so that the motor can drive the transmission shaft 3 to rotate through the commutator 1, and then drive the transmission roller 4 to rotate by relying on the transmission shaft 3. At this time, under the drive of the transmission roller 4, the conveyor belt 5 realizes the conveying work.

[0022] As Figure 5 shown, a plurality of transmission parts 31 are provided on the transmission shaft 3, and a connecting part 41 is provided on the transmission roller 4; the actuator 6 is used to drive the connecting part 41 to dock or separate from the transmission part 31; In the above structure, since a plurality of transmission rollers 4 are provided on each transmission shaft 3, in order to realize individual shipment or container storage, the connecting part 41 on the corresponding transmission roller 4 needs to be docked with the transmission part 31 to realize the circumferential positioning of the transmission shaft 3 and the transmission roller 4, so as to drive a single conveyor belt 5 to rotate to realize the container conveying; Among them, the actuator 6 is an action component, which is designed to drive the connecting part 41 to displace, so that the connecting part 41 is docked with the transmission part 31 to realize torque transmission, or to separate the two relatively to stop driving the conveyor belt 5.

[0023] The structural design of this conveying mechanism drives the conveyor belt 5 to move by setting the commutator 1, the connecting shaft 2, the transmission shaft 3, and the transmission roller 4. In this way, only one motor can drive all the conveyor belts 5 to move through the commutator 1, the connecting shaft 2, and the transmission shaft 3. This reduces the number of driving parts used and is conducive to maintenance; Meanwhile, the connecting part 41 on each driving roller 4 is connected to the driving part 31 on the transmission shaft 3 through a separate actuator 6, so that one or more conveyor belts 5 can be selectively driven to realize the picking and supplying of the cargo box; due to the conveyor belt structure, it has good structural strength and is suitable for the distribution of heavy cargo boxes.

[0024] As Figure 5 shown, the driving part 31 has a first conical surface 301, the connecting part 41 has a second conical surface 401, the end of the driving roller 4 is provided with a spline structure, and a connecting ring 42 is arranged on the driving roller 4. The actuator 6 includes a slip ring 61 and an air inflation ring 62. Among them, the slip ring 61 is slidably matched with the driving roller 4, and the slip ring 61 is located between the spline structure at the end of the driving roller 4 and the connecting ring 42; the air inflation ring 62 is sleeved on the slip ring 61, and the air inflation ring 62 abuts against the connecting ring 42; the connecting part 41 is slidably matched with the spline structure at the end of the driving roller 4 and abuts against the air inflation ring 62; In the above structure, the second conical surface 401 of the connecting part 41 is used to connect with the first conical surface 301 of the driving part 31. Since the driving part 31 is a part of the transmission shaft 3, and the connecting part 41 is in spline fit with the driving roller 4, after the driving part 31 and the connecting part 41 are butted, the torque of the transmission shaft 3 can be transmitted to the driving roller 4 by relying on the frictional force, so as to realize the driving of the conveyor belt 5; Among them, the spline fit structure between the connecting part 41 and the driving roller 4 not only realizes the circumferential positioning of the connecting part 41 relative to the driving roller 4, but also does not interfere with the displacement of the connecting part 41; Among them, the actuator 6 includes a slip ring 61 and an air inflation ring 62, so it is convenient to install on the driving roller 4. When transmission is required, the air inflation ring 62 is inflated, and then the connecting part 41 is pushed to displace to butt against the driving part 31.

[0025] As Figure 6 shown, the actuator 6 further includes a sliding plate 63. The slip ring 61 includes a ring part 611 and a plate part 612. The connecting part 41 is provided with a ventilation groove 402. Among them, the ring part 611 is slidably matched with the driving roller 4; the plate part 612 is connected to the ring part 611, the plate part 612 is a hollow structure, and an opening 601 is arranged corresponding to the ventilation groove 402; the sliding plate 63 and the plate part 612 are relatively located on both sides of the air inflation ring 62, the sliding plate 63 is slidably matched with the connecting ring 42, and the plate part 612 is slidably matched with the connecting part 41; In the above structure, since the actuator 6 uses the air inflation ring 62 for driving work, a connecting pipeline is required. To avoid the problem of pipeline interference during rotation, a sliding plate 63 is provided, and the slip ring 61 is set as a two-part structure of a ring part 611 and a plate part 612; When it works, the inflatable ring 62 is connected to an air supply pipeline. The inner ring of the inflatable ring 62 is in sliding fit with the driving roller 4 through the ring part 611, is in sliding fit with the connecting part 41 through the plate part 612 on one side, and is in sliding fit with the connecting ring 42 through the sliding plate 63 on the other side. The sliding plate 63 is arranged as an annular part and is sleeved on the driving roller 4; Thus, when continuing to work, as air is inflated into the inflatable ring 62, the sliding plate 63 will abut against the side wall of the connecting ring 42, and then push the connecting part 41 to move towards the transmission part 31 to achieve docking fit; During rotation, the inflatable ring 62 will apply an axial force to the connecting part 41 and the connecting ring 42 to ensure the stability of the connection between the connecting part 41 and the transmission part 31. At the same time, since the inflatable ring 62 is in sliding fit with the driving roller 4 through the sliding ring 61 and the sliding plate 63, it is not circumferentially positioned. Under the traction of the air supply pipeline, the sliding ring 61, the inflatable ring 62 and the sliding plate 63 will not rotate, thus avoiding the occurrence of structural interference problems and ensuring the stability of application; Among them, the plate part 612 is arranged as a hollow structure and is provided with an opening 601, and the connecting part 41 is provided with a ventilation groove 402. Thus, air can be supplied through the plate part 612, and then the conical surfaces of the transmission part 31 and the connecting part 41 can be purged through the ventilation groove 402, so as to realize self-cleaning work, ensure no debris, and avoid problems that affect transmission; Specifically, both the connecting part 41 and the sliding ring 61 are annular parts, and a plurality of ventilation grooves 402 are provided, so that they can surround the driving roller 4. The opening on the sliding ring 61 is arranged as an annular opening, which is convenient for supplying gas to the ventilation groove 402.

[0026] The unmanned aerial vehicle end delivery cabinet of the present invention includes the above-mentioned conveying mechanism, and also includes a driven roller 7, a cabinet body 8, a transfer component 9, a sliding door 10, a lifter 11, a first conveying component 12, a transfer component 13 and a photovoltaic component 14.

[0027] As Figure 7 、 Figure 10 、 Figure 13 、 Figure 15 and Figure 17 shown, the cabinet body 8 includes a bearing seat 81, a connecting rod 82, a cabinet frame 83, a skin 84 and a cover shell 85. Among them, the driven roller 7 is parallel to the driving roller 4 and supports the conveyor belt 5; the bearing seats 81 are arranged at both ends of the driven roller 7 and the driving roller 4; the connecting rod 82 is longitudinally arranged and connects two adjacent bearing seats 81; the cabinet frame 83 is connected to the connecting rod 82; the skin 84 is arranged on the cabinet frame 83; the cover shell 85 is buckled on the cabinet frame 83; With the above structure, the driven roller 7 is used to cooperate with the driving roller 4 to realize the support at both ends of the conveyor belt 5, so that the conveyor belt 5 can rotate; In the above structure, the bearing seat 81 is used for supporting the driving roller 4 and the driven roller 7, and they are rotationally connected; since the commutator 1, the transmission shaft 3, and the driving roller 4 are all arranged longitudinally in multiple numbers, multiple bearing seats 81 need to be provided, and then the bearing seats 81 are connected by multiple connecting rods 82 to be integrated into an integral structure, thereby ensuring the stability of the overall structure; Among them, the cabinet frame 83 is the main frame of the distribution cabinet. Integrate the above-mentioned transmission components in the cabinet frame 83, and connect and fix the connecting rod 82 to the cabinet frame 83. Then cover the cabinet frame 83 with a skin 84 to ensure the appearance is beautiful. Finally, fasten the cover 85 to enclose the cabinet frame 83, and the front part of the cover 85 is open to facilitate the setting of an opening and closing door for convenient pick-up.

[0028] As Figure 11 and Figure 18 shown, the interior of the cabinet body 8 is provided with a storage cavity 801, a function cavity 802, an equipment cavity 803, a transfer cavity 804, and a transmission cavity 805. Among them, multiple storage cavities 801 are provided in the cabinet body 8; the function cavity 802 is arranged between multiple storage cavities 801; the equipment cavity 803 and the transfer cavity 804 are located in the middle of the cabinet body 8 and between multiple storage cavities 801; the transmission cavity 805 is arranged at the rear of the cabinet body 8 and corresponds to the storage cavity 801, the function cavity 802, the equipment cavity 803, and the transfer cavity 804; the conveying mechanism is located in the storage cavity 801 and the transmission cavity 805; In the above structure, the function cavity 802 is used to store devices such as a control terminal to realize the operation control of the components of this distribution cabinet; the equipment cavity 803 is used to place devices such as an air compressor to support the function operation of this distribution; the storage cavity 801 is used to store the cargo box, and it cooperates with the transmission cavity 805. The transmission cavity 805 is used to arrange the conveying mechanism of the present invention, and the conveyor belt 5 of the conveying mechanism extends into the storage cavity 801 to carry the cargo box; the transfer cavity 804 is used for the transfer work of the cargo box, and it can play the role of the storage cavity 801 to realize the reception or transfer of the cargo box; In this structure, the transmission cavity 805 is arranged corresponding to all other chambers to form a front-back layout structure, which is convenient for the connection between components.

[0029] As Figures 11 - 18 shown, the transfer cavity 804 is located above the equipment cavity 803. The conveyor belt 5 is used to horizontally carry a cuboid-shaped cargo box. Among them, the sliding door 10 is slidably arranged on the skin 84 and corresponds to the transfer cavity 804; the elevator 11 is arranged in the transfer cavity 804; the first conveying component 12 is arranged on the elevator 11; the transfer component 13 is used to convey the cargo box to the conveyor belt 5 and the first conveying component 12, and receive the cuboid-shaped cargo box supplied by the conveyor belt 5 and the first conveying component 12, and the transfer component 13 is obliquely arranged to carry the cuboid-shaped cargo box; In the above structure, after the sliding door 10 is opened, the first conveying component 12 located in the transfer cavity 804 is opened. At this time, the unmanned aerial vehicle can place the cargo box on the first conveying component 12. Subsequently, driven by the elevator 11, the first conveying component 12 descends, and the cargo box enters the distribution cabinet. Then, the first conveying component 12 transfers the cargo box to the transfer component 13, and finally the transfer component 13 sends the cargo box to the conveyor belt 5; In the above work process, it can also be operated in reverse to send the cargo box located on the conveyor belt 5 to the first conveying component 12, and then picked up by the unmanned aerial vehicle; Among them, the conveyor belt 5 is placed horizontally to stably carry the cargo box, while the transfer component 13 is obliquely arranged to carry the cuboid-shaped cargo box. This structure can reduce the space occupied by the transfer component 13 in the distribution cabinet, making the overall structure of the distribution cabinet more compact. Compared with the existing transfer structures using three-axis displacement modules or robotic arms, it has the advantage of a smaller volume and can reduce the floor area of the distribution cabinet.

[0030] As Figure 13 and Figure 14 shown, the transfer component 13 includes a longitudinal module 131, a transverse module 132, a second conveying component 133, a baffle 134, a motor 135, a winding wheel 136 and a cable 137. Among them, two longitudinal modules 131 are arranged in parallel on the cabinet frame 83; two transverse modules 132 are arranged in parallel on the longitudinal module 131, one of the transverse modules 132 is fixedly connected to the longitudinal module 131, and the other transverse module 132 is connected to the movable end of the longitudinal module 131; the second conveying component 133 is obliquely arranged on the transverse module 132 located at the movable end of the longitudinal module 131; the baffle 134 is arranged on the second conveying component 133; the motor 135 is arranged on the transverse module 132 fixedly connected to the longitudinal module 131; the winding wheel 136 is arranged on the main shaft of the motor 135 and is connected to the baffle 134 through the cable 137; In the above structure, the transfer component 13 is used for the transfer of the cargo box between the conveyor belt 5 and the first conveying component 12. When it works, the longitudinal module 131 and the transverse module 132 form a two-axis positioning mechanism, which can drive the second conveying component 133 to displace, so that it can correspond to different conveyor belts 5 and the first conveying component 12; Among them, both the first conveying component 12 and the second conveying component 133 are set as conveyor belt structures. Since the second conveying component 133 is obliquely arranged, the baffle 134 is set. The baffle 134 can be connected to the frame of the second conveying component 133 to block the cargo box and prevent the cargo box from sliding; When the longitudinal module 131 and the transverse module 132 drive the second conveying component 133 to correspond to the conveyor belt 5 or the first conveying component 12, the conveyor belt 5 or the first conveying component 12 can convey the cargo box to the second conveying component 133, and then the second conveying component 133 can convey the cargo box to the conveyor belt 5 or the first conveying component 12; In order to ensure the stable conveying of the second conveying component 133, the surface of the conveyor belt as an operating component can be provided with protrusions and other protective treatments to ensure that the cargo box can be lifted in a large-angle inclined state; As described above, the fixed transverse module 132 drives the motor 135, the winding wheel 136 and the cable 137 to displace to synchronize the moving posture of the second conveying component 133; The motor 135 of the transfer component 13 tensions the second conveying component 133 by winding or releasing the cable 137, thereby cooperating with the transverse module 132 to support the second conveying component 133, thereby reducing the load of the transverse module 132 and ensuring the stability of the structure; On the other hand, the obliquely arranged second conveying component 133 can also reduce the height of the cargo box to improve the convenience of manual picking.

[0031] As Figure 18 and Figure 19 shown, there are multiple functional cavities 802, which are selectively used for ventilation or installing the photovoltaic module 14. The photovoltaic module 14 includes a lifting member 141, a push plate 142, a photovoltaic panel 143, a guide frame 144, a carrier 145 and a guide wheel 146. Among them, the lifting member 141 is arranged in the functional cavity 802 and is connected to the cabinet frame 83. The top of the functional cavity 802 is open; The push plate 142 is arranged on the movable end of the lifting member 141; One side of the photovoltaic panel 143 is rotatably connected to the push plate 142; The guide frame 144 is arranged on the side of the photovoltaic panel 143 away from the push plate 142; The carrier 145 is arranged on the skin 84, and the carrier 145 has a trapezoidal block structure; The guide wheel 146 is arranged at one end of the carrier 145 close to the photovoltaic panel 143; As described above, the functional cavity 802 opened in the cabinet frame 83 can be selectively used for ventilation, which is beneficial to avoiding damage to the cargo box caused by factors such as temperature and humidity, thereby ensuring a good storage environment for the cargo box; At the same time, the functional cavity 802 can also be used to install the photovoltaic module 14 to realize the power supply for the distribution cabinet and the drone; Specifically, the photovoltaic panel 143 is arranged in the functional cavity 802 through the lifting member 141. In this way, when the lifting member 141 drives the push plate 142 to move, the photovoltaic panel 143 can be pushed out of the functional cavity 802 to receive light and supply power; In this structure, since the photovoltaic module 14 is installed by the lifting member 141, it can be selectively extended or retracted from the cabinet, which improves the structural compactness and is also beneficial to avoiding the influence of bad weather on the photovoltaic panel, thus having a good application effect; Among them, in order to improve the working efficiency of the photovoltaic panel 143, a carrier 145 is provided to carry the photovoltaic panel 143, so that the photovoltaic panel 143 is inclined, thereby better receiving sunlight; Among them, guide wheels 146 are provided on the carrier 145. In this way, when the lifting member 141 retracts, driven by the push plate 142, the end of the photovoltaic panel 143 away from the push plate 142 will be lifted, so as to facilitate storage into the functional cavity 802; a guide frame 144 is provided on the photovoltaic panel, and the guide frame 144 has a wedge surface, which is convenient to insert into the functional cavity 802 and realize the sealing of the top opening of the functional cavity 802; Furthermore, the guide frame 144 is set as a hollow structure, and a counterweight block is arranged inside the side facing the carrier 145. In this way, when the photovoltaic panel 143 is pushed out, it can tend to the carrier 145 under the action of the counterweight and be supported by the carrier 145. During the pushing process, the guide wheels 146 rotate to avoid frictional damage to the photovoltaic panel 143.

[0032] As Figure 12 shown, the sliding door 10 is composed of two shells 1011 that can be relatively separated or approached. The shell 1011 is a hollow structure, and a power storage device is arranged inside the shell 1011; In the above structure, the sliding door 10 is set as two shells 1011 that can be relatively opened and closed, so as to facilitate the enclosure of the first conveying component 12, and it can be opened again before the arrival of the drone; To make full use of the space, a power storage device is arranged inside the shell 1011, including related charging components, to realize charging the drone and improve the endurance of the drone.

[0033] The application method of the drone end delivery cabinet of the present invention includes the following steps: S1. The sliding door 10 is opened to make the first conveying component 12 at the top of the elevator 11 open, S2. The drone lands and places the cargo box on the first conveying component 12. Subsequently, the elevator 11 drives the first conveying component 12 and the cargo box to descend, S3. Drive the second conveying component 133 to move through the longitudinal module 131 and the transverse module 132 to correspond to the transfer cavity 804, S4. The first conveying component 12 transfers the cargo box to the second conveying component 133, S5. Drive the second conveying component 133 and the cargo box to move through the longitudinal module 131 and the transverse module 132 to correspond to the storage cavity 801, S6. The second conveying component 133 transfers the cargo box onto the conveyor belt 5. Among them, when the longitudinal module 131 operates, the motor 135 drives the winding wheel 136 to rotate, so as to tension the second conveying component 133 by winding or releasing the cable 137.

[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
