Description

Technical Field

[0001] The invention relates to a delivery device, in particular to an unmanned aerial vehicle delivery device. Background Art

[0002] As my country's research on unmanned aerial vehicles continues to deepen, the scope of application of unmanned aerial vehicles has been increasingly expanded, and the functions of unmanned aerial vehicles have become increasingly powerful, such as military strikes, surveillance, communications, mapping, disaster relief, etc. For the existing unmanned aerial vehicle delivery devices on the market, the principle is a four-bar linkage mechanism. When the delivery device is loaded with a heavy load, the friction between the release rod and the base is extremely large. The low-power actuator cannot drag it, and the delivery object cannot be released. When it is replaced with a high-power actuator, it will bring serious power consumption and increased weight. In addition, when the drone is in flight, the release rod may be pulled away from the base due to vibration or damage to the actuator, causing the delivery object to fall, causing unnecessary losses or even casualties. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a drone delivery device which can carry large-mass delivery objects, has a simple structure, works reliably, and can deliver quickly.

[0004] The technical solution of the present invention is:

[0005] A drone delivery device comprises a connecting plate, on which two quick-release connectors are symmetrically arranged, and below the connecting plate are two vertically arranged fixed plates, and between the lower ends of the two fixed plates are hinged two mutually engaging delivery hooks, and a track plate is hinged on the upper end of one of the delivery hooks, and a slideway groove approximately in an L shape is provided on the track plate, and a bearing that matches the slideway groove clearance is provided on the upper end of the other delivery hook and is located in the slideway groove; a servo is provided on the outer side of one of the fixed plates, and the output end of the servo is hinged to the upper end of the track plate through a crank-connecting rod assembly, and is used to drive the track plate to swing up and down with the upper end of one of the delivery hooks as the axis, thereby driving the lower ends of the two delivery hooks to open and close through the cooperation of the slideway groove and the bearing.

[0006] As a further preference, a lithium battery and a receiver are provided on the upper and lower parts of the servo respectively, and the servo is electrically connected to the lithium battery via the receiver, so as to use an independent remote controller to control the servo movement to achieve the delivery.

[0007] As a further preference, a shell is provided on one of the fixing plates, and a side cover is provided on the other fixing plate, the shell and the side cover are buckled together, and the steering gear, the receiver and the lithium battery are located in the shell.

[0008] As a further preference, a switching switch is also provided on the shell, and the signal output end of the switching switch is connected to the signal input end of the servo through a signal line, and one signal input end of the switching switch is connected to a receiver for receiving a control signal of an independent remote control through the receiver; the other signal input end of the switching switch is connected to a PWM socket provided on the shell for accessing the output signal of the UAV flight control.

[0009] As a further preference, a power switch is provided on the housing, and the power switch is connected between the lithium battery and the receiver, and is used to control the power supply of the receiver and the steering gear.

[0010] As a further preference, blind holes are correspondingly provided on the lower opposite surfaces of the two delivery hooks, and a pressure spring is provided between the two blind holes to assist the opening and delivery of the two delivery hooks.

[0011] As a further preference, two groups of mutually corresponding and interlocking semicircular protrusions and grooves are provided on the opposite surfaces in the middle of the two releasing hooks.

[0012] As a further preference, the fixing plate is in an inverted "convex" shape, and two rectangular long holes are respectively provided on the upper and lower parts of the fixing plate to facilitate the installation of the steering gear and reduce weight.

[0013] The beneficial effects of the present invention are as follows: since the output end of the servo engine is hinged to the upper end of the track plate through a crank-connecting rod assembly, the crank-connecting rod assembly drives the track plate to swing up and down with the upper end of one of the delivery hooks as the axis, thereby driving the lower ends of the two delivery hooks to open and close through the cooperation of the slideway groove and the bearing; it can mount large-mass delivery objects, has a simple structure, and reliable operation; the opening and closing of the two delivery hooks can be achieved by rotating the servo engine 30 degrees, and delivery is rapid.

DETAILED DESCRIPTION

[0023] like Figure 1-Figure 8 As shown, the present invention relates to a drone delivery device, including a horizontally arranged connecting plate 3, on which two quick-release connectors 4 are symmetrically fixed at both ends by screws, and the quick-release connector 4 includes a base, a sleeve is hinged at the upper end of the base, and the free end of the sleeve is connected to the base by bolts.

[0024] Two vertically arranged fixing plates 13 are connected by screws below the connecting plate 3. The fixing plates 13 are inverted "convex" shapes, and two rectangular long holes are respectively provided at the upper and lower parts of the fixing plates 13. Two mutually interlocking delivery hooks 1 are respectively hinged by pins 10 between the lower ends of the two fixing plates 13. Two groups of mutually corresponding and interlocking semicircular protrusions 102 and grooves are provided on the opposite faces of the middle parts of the two delivery hooks 1. Trapezoidal grooves 101 are symmetrically provided on the opposite faces of the lower parts of the two delivery hooks 1 for hanging delivery objects. The upper parts of the two delivery hooks 1 are fork-shaped. A track plate 11 is hinged at the upper end of one of the delivery hooks 1 by a pin. A slideway groove 1101 is provided on the track plate 11. The slideway groove 1101 is an approximately L-shaped slideway composed of long grooves and short grooves that are vertically connected to each other. A bearing 17 that is clearance-matched with the slideway groove 1101 is installed at the upper end of the other delivery hook 1 by a pin, and the bearing 17 is located in the slideway groove 1101.

[0025] A servo 14 is installed on the upper outer side of one of the fixed plates 13. The output end of the servo 14 is inserted between the two fixed plates 13 through a rectangular long hole located above and is hinged to the flange of the upper end of the track plate 11 through a crank connecting rod assembly 12 using a pin 18, which is used to drive the track plate 11 to swing up and down with the upper end of one of the delivery hooks 1 as the axis, thereby driving the lower ends of the two delivery hooks 1 to open and close through the cooperation of the slideway groove and the bearing 17. Blind holes are correspondingly provided on the opposite surfaces of the lower parts of the two delivery hooks 1, and a pressure spring 19 is provided between the two blind holes to assist the opening and delivery of the two delivery hooks 1.

[0026] A lithium battery 16 and a receiver 15 are fixed on the upper and lower sides of the steering gear 14, respectively. The steering gear 14 is electrically connected to the lithium battery 16 through the receiver 15, and is used to use an independent remote control to control the action of the steering gear 14 to achieve delivery. A housing 5 is fixed to one of the fixing plates 13 on which the steering gear 14 is installed by screws, and a side cover 2 is fixed to the other fixing plate 13. The housing 5 and the side cover 2 are buckled together through a docking socket and the two fixing plates 13 are buckled therein. The steering gear 14, the receiver 15 and the lithium battery 16 are located in the housing 5. The lower part of the delivery hook 1 passes through the openings correspondingly arranged at the lower ends of the housing 5 and the side cover 2.

[0027] A switching switch 9 is also provided on the shell 5. The signal output end of the switching switch 9, that is, the common wiring terminal, is connected to the signal input end of the servo 14 through a signal line. A signal input end corresponding to the RC end of the switching switch 9 is connected to the signal output end of the receiver 15, which is used to receive the control signal of the independent remote control through the receiver 15 and control the action of the servo 14; another signal input end corresponding to the PWM end of the switching switch 9 is connected to the PWM socket 8 provided on the shell 5, which is used to access the output signal line of the UAV flight control, so as to use the UAV remote control for delivery control.

[0028] A toggle power switch 6 is mounted on the housing 5, and the power switch 6 is connected between the lithium battery 16 and the receiver 15, and is used to control the power supply of the receiver 15 and the steering gear. A charging socket 7 is also provided on the housing 5, and the charging socket 7 is electrically connected to the lithium battery 16, and is used to charge the lithium battery 16.

[0029] The drone delivery device is installed on the drone's rack through a quick-release connector 4. The delivery object is hung in the trapezoidal groove 101 of the two delivery hooks 1 through a hanging rope or other hanging parts. The power switch 6 is turned to the ON position, and the receiver 15 and the servo are powered on and standby; when the switch 9 is turned to the RC end, the control signal of the independent remote controller is received through the receiver 15 and the servo action is controlled; when the switch 9 is turned to the PWM end, the servo action can be controlled by using the drone remote controller through the drone flight control. When the servo is in action, it rotates counterclockwise about 30 degrees, driving the crank connecting rod assembly 12 to rotate counterclockwise, so that the track plate 11 swings downward with one of the upper ends of the delivery hooks 1 as the axis. At this time, the bearing 17 slides from the short groove of the slideway groove into the long groove, and the lower ends of the two delivery hooks 1 are quickly opened under the action of the pressure spring 19 to achieve delivery. Then the steering gear is reset, and the track plate 11 is driven to swing upward through the crank connecting rod assembly 12. At this time, the bearing slides from the long groove of the slideway groove into the short groove, so that the upper ends of the two release hooks 1 are separated, and the lower ends of the two release hooks 1 compress the pressure spring to achieve closed reset.
