Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicle delivery, and in particular to a unmanned aerial vehicle delivery device. Background Art

[0002] A drone is an aircraft that can fly autonomously or remotely without human control. It is controlled by radio remote control equipment and self-contained program control devices. In some cases, drones can also be operated completely or intermittently autonomously by onboard computers. As an emerging scientific and technological product, drones can be used efficiently in many fields. As an emerging scientific and technological product, drones can be used efficiently in many fields.

[0003] With the continuous development of drone technology, the application fields of drones are getting bigger and bigger. In some commercial performances or fishing bait scenarios, drone users often need to use drones to deliver rewards or granular bait for fishing. These drone operators usually install a simple dispenser on the drone. This simple dispenser uses a rotating hook to hang the delivery bag or water-soluble bag. After that, no one can fly to the delivery location, and then the hook can rotate to lower the delivery bag or water-soluble bag, so that the delivery bag containing prizes or the water-soluble bag containing fishing bait falls into the delivery area.

[0004] The above-mentioned drone delivery device has a relatively simple delivery structure when used in commercial performances or fishing nests. After a single delivery, it is often necessary to return to the base to replenish the delivered items. It cannot meet the needs of the drone to load prizes or water-soluble bags at a time for multiple on-demand deliveries. In addition, the containers for drones to mount delivered items are mostly non-streamlined structures, which leads to greater air resistance when the drone delivers items, which is not conducive to the stable flight of the drone when delivering items, thereby affecting the stable delivery of items. For this reason, we propose a drone delivery device. Summary of the invention

[0005] The main purpose of the present invention is to provide a drone delivery device. The present invention provides a double-headed base plate that can be installed under the drone, and then cooperates with the delivery tube to install a delivery mechanism. At the same time, with the effective drive of the driving mechanism, the indexing rotation of the rotating frame inside the delivery mechanism can be realized. Commercial performance delivery items or water-soluble bags filled with fishing bait can be placed in multiple groups of U-shaped grooves in the rotating frame for loading, and then blocked with the help of the guiding mechanism. Through the precise control of the delivery mechanism and the driving mechanism, accurate delivery of items can be achieved to meet the needs of various application scenarios such as commercial performances and fishing, and it is ensured that the drone body can be loaded and delivered multiple times in a single time when delivering commercial performance delivery items or water-soluble bags filled with fishing bait. The warhead cover design of the guiding mechanism can effectively guide the airflow, enhance the stability of the drone body during the delivery process, reduce the delivery error caused by airflow disturbance, and effectively solve the problems in the background technology.

[0006] To achieve the above object, the technical solution adopted by the present invention is:

[0007] A drone delivery device comprises a double-headed base plate, a delivery tube, a transfer mechanism, a driving mechanism and a guiding mechanism, wherein the double-headed base plate is fastened to the bottom shell of the drone body by bolts, a delivery tube is fixed below the double-headed base plate, and a strip-shaped leak for dropping objects is provided at the lower tube wall of the delivery tube away from the double-headed base plate, a transfer mechanism for separating and storing objects is installed in the delivery tube above the strip-shaped leak, guiding mechanisms for assisting the drone body to fly stably and perform precise delivery are installed at both ends of the delivery tube, and a driving mechanism for driving a rotating frame is installed between the rear tube disk of the delivery tube away from the guiding mechanism and the transfer mechanism, and a baffle for guiding objects to fall at the strip-shaped leak is installed on the frame of the rotating frame.

[0008] The U-shaped groove is provided with a rotating plate groove and a matching groove at both ends of the groove edge, and a baffle for movably blocking the U-shaped groove is inserted into the U-shaped groove between the rotating plate groove and the matching groove. A rotating plate for inserting into the rotating plate groove is symmetrically protruded on one side of the plate body of the baffle, and the rotating head plate is rotatably installed in the rotating plate groove by bolts. A rubber resisting strip for inserting into the U-shaped groove is bonded to the outer plate body of the baffle away from the rotating head plate, and a rubber retaining strip for resisting the rubber resisting strip is bonded into the groove cavity of the matching groove, and a U-shaped blocking plate for resisting the baffle is fixed in the groove opening on one side of the U-shaped groove close to the rear disc of the throwing tube.

[0009] The following effects can be achieved by adopting the above-mentioned preferred technical scheme. After the rotating frame of the transfer mechanism is inserted into the throwing tube, the rotating head plate of the baffle can be installed at the rotating plate groove of the rotating frame for movement, so that the baffle can cooperate with the rubber abutment strip to abut between the rubber baffle strip and the U-shaped groove of the rotating frame to form a structure for placing objects to be put in. Then, commercial performance objects or water-soluble bags containing fishing bait can be placed in the U-shaped groove. After the U-shaped groove of the rotating frame is rotated to a position away from the strip leakage opening, the baffle can be placed on the rubber baffle strip and the inner wall of the throwing tube for support. When the baffle is rotated to the position of the strip leakage opening of the throwing tube, it loses support and the baffle can be flipped downward due to gravity, so that the commercial performance objects or water-soluble bags containing fishing bait in the U-shaped groove can fall and be thrown from the strip leakage opening. When the rotating frame continues to rotate, the baffle can enter the U-shaped groove from the strip leakage opening of the throwing tube for re-blocking, and the multiple groups of U-shaped grooves arranged in a ring shape in the rotating frame can be rotated to the strip leakage opening for multiple times to perform the throwing action.

After the inner shaft tube is fixed at the core hole of the rotating frame, the rotating frame can flexibly rotate in the bearing at the head tube with the inner shaft tube, and then the key hole groove of the inner shaft tube can be inserted into the conveying shaft with a straight key of the indexing motor for key connection. At the same time, after the indexing motor is installed at the rear barrel disk of the throwing barrel, the indexing motor can drive the rotating frame to rotate as needed through the inner shaft tube, so that the baffle at the rotating frame can be conveniently dropped and rotated and retracted at the strip leakage mouth of the throwing barrel, thereby realizing the indexing rotation of the rotating frame.

[0014] Furthermore, the guiding mechanism comprises a tail mounted disc, a head mounted disc, a bullet head cover and a rubber strip, the arc-shaped counter-plates of the tail mounted disc and the head mounted disc are clamped on the outside of the barrel mouth and the barrel tail of the barrel, and the arc-shaped counter-plates of the tail mounted disc and the head mounted disc are locked outside the barrel by bolts, the back disc surfaces of the tail mounted disc and the head mounted disc away from the barrel are fixed with bullet head covers for guiding airflow, and air holes are provided under the cover bodies of the bullet head covers, and rubber strips for clamping the barrel are bonded to the inner walls of the arc-shaped counter-plates of the tail mounted disc and the head mounted disc;

At the same time, there are warhead covers on the outside of the tail-mounted disk and the head-mounted disk to guide the airflow, which helps to stabilize the UAV body during the launching process, and the warhead cover can be connected to the outside through the air vent.

[0016] Furthermore, the surfaces of the tail plate and the head plate are provided with plate holes, and the plate hole of the tail plate passes through a housing with an indexing motor;

[0018] Furthermore, an inner support plate is fixed inside the warhead cover of the tail mounted disc, and a controller for controlling the indexing motor is installed on the plate surface of the inner support plate;

[0019] By adopting the above preferred technical solution, the following effects can be achieved: a controller can be installed on the inner support plate at the warhead cover behind the tail mounting plate, so that the controller can control the indexing motor to perform indexing rotation.

The design of the pressure belt mechanism enhances the connection stability between the drone body and the double-headed base plate, avoiding delivery errors caused by the shaking of the drone body during the delivery process.

[0022] Furthermore, a rib groove penetrating the plate body is provided on the side of the baffle plate, and a shrinkage groove having the same length as the strip body is provided in the rubber support strip on one side of the baffle plate;

[0023] By adopting the above-mentioned preferred technical solution, the following effects can be achieved: the rib grooves opened on the side of the baffle and the shrinkage grooves opened in the rubber support strip help to reduce the weight of the entire device and improve the endurance of the drone body.

After the rotating frame 5 of the transfer mechanism 4 is inserted into the casting tube 2, the rotating head plate 10 of the baffle plate 9 can be installed at the rotating plate groove 7 of the rotating frame 5 for movement, so that the baffle plate 9 can cooperate with the rubber abutment strip 12 to abut between the rubber abutment strip 13 and the U-shaped groove 6 of the rotating frame 5 to form a structure for placing objects to be placed. Then, commercial performance objects or water-soluble bags containing fishing bait can be placed in the U-shaped groove 6. After the U-shaped groove 6 of the rotating frame 5 is rotated to a position away from the strip-shaped leak 3, the baffle plate 9 can be The baffle plate 9 is placed on the rubber baffle strip 13 and the inner wall of the throwing tube 2 to obtain support. When the baffle plate 9 rotates to the position of the strip leakage 3 of the throwing tube 2, the support is lost and the baffle plate 9 can flip downward due to gravity, so that commercial performance items or water-soluble bags containing fishing bait in the U-shaped groove 6 can fall and be thrown from the strip leakage 3. When the rotating frame 5 continues to rotate, the baffle plate 9 can enter the U-shaped groove 6 from the strip leakage 3 of the throwing tube 2 for re-blocking, and the multiple groups of U-shaped grooves 6 arranged in a ring distribution in the rotating frame 5 can be rotated to the strip leakage 3 for multiple times to perform the throwing action.

[0044] The driving mechanism 14 includes an inner shaft tube 15, a bearing 16 and an indexing motor 18. A core hole is formed through the end surface of the rotating frame 5 between the U-shaped grooves 6, and the tube body of the inner shaft tube 15 is fixed in the core hole. A disc hole for interference-fitting the outer ring of the bearing 16 is formed on the surface of the rear disc of the throwing tube 2 on one side of the inner shaft tube 15, and the shaft head of the inner shaft tube 15 is interference-fitted at the inner shaft ring of the bearing 16.

At the same time, after the indexing motor 18 is installed at the rear barrel disk of the throwing barrel 2, the indexing motor 18 can drive the rotating frame 5 to rotate as needed through the inner shaft tube 15, so that the baffle 9 at the rotating frame 5 can be conveniently dropped and rotated and retracted at the strip leakage mouth of the throwing barrel 2, thereby realizing the indexing rotation of the rotating frame 5.

[0046] The guiding mechanism 19 includes a tail mounted disc 20, a head mounted disc 21, a bullet cover 22 and a rubber pressure strip 24. The arc-shaped plates of the tail mounted disc 20 and the head mounted disc 21 are clamped on the outside of the barrel mouth and the barrel tail of the barrel 2, and the arc-shaped plates of the tail mounted disc 20 and the head mounted disc 21 are locked outside the barrel 2 by bolts. The back disc surfaces of the tail mounted disc 20 and the head mounted disc 21 away from the barrel 2 are fixed with a bullet cover 22 for guiding airflow, and a vent hole is provided under the cover body of the bullet cover 22. The inner walls of the arc-shaped plates of the tail mounted disc 20 and the head mounted disc 21 are bonded with a rubber pressure strip 24 for clamping the barrel 2.

[0047] By adopting the above-mentioned preferred technical solution, the following effects can be achieved. The tail-mounted disk 20 and the head-mounted disk 21 of the guiding mechanism 19 are pressed against the rubber strip 24 and covered outside the delivery tube 2. Then the tail-mounted disk 20 and the head-mounted disk 21 are locked at the delivery tube 2 by bolts and are not easy to fall off. At the same time, there is a warhead cover 22 on the outside of the tail-mounted disk 20 and the head-mounted disk 21, which can be used to guide the airflow, which helps the stability of the UAV body 26 during the delivery process, and the warhead cover 22 can be connected to the outside through the air vent.

[0048] The surfaces of the tail plate 20 and the head plate 21 are provided with plate holes, and the plate holes of the tail plate 20 pass through the housing of the indexing motor 18;

[0051] By adopting the above preferred technical solution, the following effects can be achieved: the controller 25 can be installed on the inner support plate 23 at the warhead cover 22 behind the tail plate 20, so that the controller 25 can control the indexing motor 18 to perform indexing rotation.

The top of the double-headed plate body of the double-headed substrate 1 is locked with a "J"-shaped pressing seat 29 by bolts, and a "J"-shaped frame 28 clamped outside the drone body 26 is pressed between the "J"-shaped pressing seat 29 and the double-headed substrate 1.

[0054] The side of the baffle 9 is provided with a rib groove penetrating the plate, and the rubber support strip 12 on one side of the baffle 9 is provided with a shrinkage groove having the same length as the strip;

[0055] By adopting the above-mentioned preferred technical solution, the following effects can be achieved. The rib grooves opened on the side of the baffle 9 and the shrinkage grooves opened in the rubber retaining strip 12 help to reduce the weight of the entire device and improve the endurance of the drone body 26. At the same time, the rubber retaining strip 12 with the shrinkage groove can also be easily inserted into the U-shaped groove 6 at the rubber retaining strip 13.

[0056] It should be noted that the present invention is a drone delivery device, and the operation method of the delivery device is as follows:

[0057] First, the double-headed base plate 1 is locked under the drone body 26 by bolts, and then the "X"-shaped frame 28 of the belt pressing mechanism 27 can be pressed on the surface of the drone body 26 and the double-headed base plate 1, and then the "X"-shaped pressing seat 29 presses the "X"-shaped frame 28 to be installed on the double-headed base plate 1, and then the baffle plate 9 is installed at the rotating plate groove 7 of the rotating frame 5 with the help of bolts with a light rod, and the baffle plate 9 can cooperate with the rubber abutment strip 12 to abut against the rubber baffle strip 13 of the U-shaped groove 6, and then the rotating frame 5 of the transfer mechanism 4 is inserted into the throwing tube 2 under the double-headed base plate 1, The inner shaft tube 15 at the rotating frame 5 can insert the shaft head into the tail barrel disc bearing 16 of the throwing tube 2 through interference fit, and then the key hole groove 17 of the inner shaft tube 15 can be inserted into the conveying shaft with a straight key of the indexing motor 18 for key connection. At the same time, after the indexing motor 18 is installed at the rear barrel disc of the throwing tube 2, the indexing motor 18 can drive the rotating frame 5 to rotate as needed through the inner shaft tube 15, so that the baffle 9 at the rotating frame 5 can fall and rotate and retract at the strip leakage of the throwing tube 2, ensuring that the indexing motor 18 can drive the rotating frame 5 to rotate at a certain degree;

[0058] And the tail plate 2 of the guiding mechanism 19 is installed with the warhead cover 22 at the rear of the throwing tube 2, and the warhead cover 22 at the rear of the tail plate 2 is provided with a controller 25 which can be used to control the indexing motor 18 of the driving mechanism 14 to rotate indexingly, and the controller 25 can be connected to the control end of the drone body 26 for power-on control, and the rotating frame 5 of the transfer mechanism 4 can be rotated to a suitable position, so that the baffle 9 at the U-shaped groove 6 can be placed in the throwing tube 2 without falling, and then commercial performance delivery items or water-soluble bags containing fishing bait can be placed between the baffle 9 and the U-shaped groove 6 to ensure that the number of items in each U-shaped groove 6 is appropriate to avoid affecting the delivery effect, and then the head plate 21 of the guiding mechanism 19 is installed with the warhead cover 22 at the tube mouth position of the throwing tube 2, and the plate body of the head plate 21 can block the notch on one side of the U-shaped groove 6 away from the U-shaped blocking plate 32;

[0059] When the drone body 26 is manually operated to fly to the commercial performance delivery area or the fishing nesting area, the rotating frame 5 can be rotated in degrees. When a certain U-shaped groove 6 rotates to a position away from the strip leakage 3, the baffle 9 is supported by the rubber baffle 13 and the inner wall of the throwing tube 2 to keep the closed state to prevent the objects from falling in advance. As the rotating frame 5 continues to rotate, when the corresponding U-shaped groove 6 rotates to the top of the strip leakage 3, the baffle 9 loses support and flips downward due to gravity, opening the bottom of the U-shaped groove 6, so that the objects in it fall from the strip leakage 3 to the target area;

[0060] Once the items are delivered, as the rotating frame 5 further rotates, the baffle 9 will regain support and flip back to its original position when it turns to the non-strip leak 3 position of the delivery tube 2, closing the U-shaped groove 6 to prepare for the next delivery. During the whole process, the guide mechanism 19 guides the airflow through its warhead cover 22 design, which helps the stability of the drone body 26 during the delivery process. The multiple groups of U-shaped grooves 6 in the rotating frame 5 can accommodate more items and deliver them one by one according to demand, ensuring that the drone body 26 can be loaded and delivered multiple times in a single load when delivering commercial performance delivery items or water-soluble bags containing fishing bait;

[0061] And the belt pressing mechanism 27 enhances the connection stability between the drone body 26 and the double-head substrate 1, ensuring that the drone body 26 will not cause delivery errors due to shaking during the delivery process. Through the precise control of the transfer mechanism 4 and the driving mechanism 14, the precise delivery of objects can be achieved to meet the needs of various application scenarios such as commercial performances and fishing. The indexing motor 18 and the controller 25 can be connected to the drone body 26 for use;

[0062] During the delivery process, the operator can configure a camera at the drone body to monitor the delivery situation in real time. When all items are delivered, the drone body can return to the take-off point or perform other tasks. The operator can turn off the power of the drone body to end the entire operation process. When the drone body 1 is installed with a delivery device, a special landing gear needs to be configured. A groove needs to be provided in the middle of the landing gear to accommodate the delivery tube for installing the guide mechanism, and the edge frame of the landing gear needs to ensure that the supporting feet of the drone body 1 can be supported, thereby ensuring that the drone body 1 can take off and land normally after the delivery device is installed under the drone body 1.
