Description

Technical Field

[0001] This utility model relates to the technical field of drone delivery devices, specifically to a drone delivery device. Background Technology

[0002] Due to their inherent characteristics, drones are used in various fields, especially in military and disaster relief. By suspending items on the bottom of the drone, they can achieve the function of targeted delivery. Therefore, existing technologies have designed drone delivery devices.

[0003] Existing drone dispensers are mostly mechanical gripper structures, with motors or electric actuators used for opening and closing. In actual deployment, the drone's control system controls the movement of the motors or electric actuators. However, the operation of the electrical components controlled by the control system requires wiring. How to arrange this wiring harness to ensure that it does not affect the operation of the mechanical gripper is a problem that designers need to consider. Therefore, this application provides a drone dispenser. Utility Model Content

[0004] The purpose of this invention is to provide a drone delivery device structure that avoids the mechanical gripper from tangling the control cable harness.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A drone delivery device includes a suspension base, a stepper motor mounted on the side of the suspension base, and a locking mechanism. The suspension base has a hollow structure with a partition inside that divides the hollow structure into two parts. The locking mechanism is located at the lower part of the hollow structure. The output shaft of the stepper motor passes through the side of the suspension base and the part extending into the hollow structure is located below the partition to drive the locking mechanism, forming a wire harness that passes through the hollow structure above the partition and then reaches the stepper motor in an avoidance state.

[0007] Furthermore, the suspension mount includes a base with a top opening and an insertion port on the bottom side. The stepper motor is mounted on the side of the suspension mount, and a top cover plate is screwed to the top of the opening of the base. The top cover plate has bolt holes for connecting the bottom of the drone.

[0008] Furthermore, the output shaft of the stepper motor is fixed to a drive shaft that is rotatably mounted on the side wall of the base via a coupling. The locking mechanism includes a hook-shaped claw that is fixed to the drive shaft. When the claw is laid flat, it closes the insertion port and has an inclined surface on its outer side, so that when the suspended object enters through the insertion port, the inclined surface pushes the drive shaft to rotate, thereby opening the insertion port.

[0009] Furthermore, guide rods are fixed at all four corners of the partition, the guide rods slide through the base, and a compressed spring is fixed at the top of the partition, with the other end of the spring abutting against the top cover plate.

[0010] Furthermore, the free end of the drive shaft rotates through the side wall of the base and extends outward. A limit rod is vertically fixed to the extended end of the drive shaft, and a limit bolt is fixedly installed on the side wall of the base to ensure a stable state that limits the rotation of the limit rod when the hook is laid flat.

[0011] Furthermore, the top cover plate is provided with a wire passage window for wire harness entry, and the side wall of the cavity structure above the partition is provided with a mounting slot for fixing aviation plugs.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention sets the suspension seat as a cavity and uses a partition to divide it into upper and lower parts. The upper part is used for the wiring of the wire harness, and the lower part is used for the stepper motor to control the operation of the locking mechanism. In this way, the wire harness is isolated from the mechanical gripping mechanism that may get tangled with the wire harness, which can effectively ensure that the wiring of the wire harness does not affect the gripping and releasing function of the mechanical gripper.

[0014] When the stepper motor drives the drive shaft to open the insertion port, the partition plate driven by the hook will compress the spring upward. After the stepper motor cancels the control of the drive shaft, the upper surface of the hook will be pressed by the partition plate under the action of the spring to achieve reset. In this way, the partition plate obtains another function in addition to isolating the wire harness, namely the function of resetting the hook. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0023] This embodiment provides a drone dispenser, mainly used to provide a drone dispenser structure that avoids the control cable entanglement with the mechanical gripper, and provides the following technical solution, which will be combined with... Figures 1-6 Please provide a detailed explanation:

[0024] Example 1:

[0025] A drone delivery device includes a suspension base 1, a stepper motor 2 and a locking mechanism 3 mounted on the side of the suspension base 1. The stepper motor 2 can be controlled by the control system on the drone to adjust its rotation angle, which is a characteristic of the stepper motor 2. The control of the stepper motor 2 by the drone control system is also existing technology, which will not be elaborated here. More importantly, the suspension base 1 is a hollow structure 4 and has a partition 5 that divides the hollow structure 4 into two parts. The locking mechanism 3 is located in the lower part of the hollow structure 4. The output shaft of the stepper motor 2 passes through the side of the suspension base 1 and the part that extends into the hollow structure 4 is located below the partition 5 to drive the locking mechanism 3. In this way, the wire harness passes through the hollow structure 4 above the partition 5 and then reaches the stepper motor 2 in an avoidance state.

[0026] This application sets the suspension seat 1 as a cavity and uses a partition 5 to divide it into upper and lower parts. The upper part is used for the wiring of the wire harness, and the lower part is used for the stepper motor 2 to control the operation of the locking mechanism 3. In this way, the wire harness is isolated from the mechanical gripping mechanism that may be entangled with the wire harness, which can effectively ensure that the wiring of the wire harness does not affect the gripping and releasing function of the mechanical gripper.

[0027] like Figures 1 to 3 Specifically, the suspension mount 1 includes a base 102 with an opening at the top and an insertion port 101 on the bottom side. The stepper motor 2 is mounted on the side of the suspension mount 1, and a top cover plate 103 is fixed to the top of the opening of the base 102 with screws. The top cover plate 103 has bolt holes 104 for connecting to the bottom of the drone. When installed and connected to the bottom of the drone, connection and disassembly can be achieved simply by passing a bolt through the bolt hole 104 and using a nut.

[0028] like Figure 1 , Figure 3 , Figure 5 , Figure 6 As shown, to achieve the gripping and releasing function, the output shaft end of the stepper motor 2 is fixed to a drive shaft 6 rotatably mounted on the side wall of the base 102 via a coupling. The locking mechanism 3 includes a hook-shaped claw 31 fixed to the drive shaft 6. When the claw 31 is laid flat, it closes the insertion inlet 101 and has an inclined surface 32 on its outer side. Please refer to [link to relevant documentation]. Figure 5 and Figure 6 When the suspended rope enters through the inlet 101, it first contacts the inclined plane 32, and the inclined plane 32 pushes the hook 31 and the drive shaft 6 to rotate around the axis of the drive shaft 6, thereby opening the inlet 101. After entering the inlet 101, the hook 31, no longer under the pushing force, returns to its original position under the action of gravity, re-closing the inlet 101. At this time, the rope is hooked on the hook 31, thus realizing the gripping function. When it is necessary to release, the control system of the UAV controls the stepper motor 2 to rotate, so that the hook 31 and the drive shaft 6 rotate around the axis of the drive shaft 6 to open the inlet 101. At this time, the rope and the cargo are released from the inlet 101 under the action of gravity, thus realizing the release function.

[0029] like Figure 1 and Figure 3 , Figure 5 As shown, in order to ensure that the hook 31 is laid flat, the free end of the drive shaft 6 rotates through the side wall of the base 102 and extends outward. The extended end of the drive shaft 6 is vertically fixed with a limit rod 9, and a limit bolt 10 is fixedly installed on the side wall of the base 102. When the hook 31 is laid flat, the limit rod 9 and the limit bolt 10 are in contact. At this time, the flatness of the hook 31 is ensured, and it waits for the stepper motor 2 to drive.

[0030] Example 2:

[0031] This embodiment optimizes the technical solution based on Embodiment 1, specifically to ensure the smooth reset of the partition 5. Please refer to [link to previous document]. Figure 3 Guide rods 7 are fixed at each of the four corners of the partition 5. The guide rods 7 slide through the base 102, which provides guidance for the up and down movement of the partition 5. A compressed spring 8 is fixed at the top of the partition 5. The other end of the spring 8 abuts against the top cover plate 103. When the stepper motor 2 drives the drive shaft 6 to open the inlet 101, the partition 5 driven by the hook 31 will compress the spring 8 upward. After the stepper motor 2 cancels the control of the drive shaft 6, the partition 5 will be pressed against the upper surface of the hook 31 by the spring 8 to achieve reset. In this way, the partition 5 obtains another function in addition to isolating the wire harness, namely the function of resetting the hook 31.

[0032] like Figure 2 and Figure 4 As shown, for better cable routing, a cable pass-through window 11 is provided on the top cover plate 103 for cable harness entry. The cable harness is led out from inside the UAV, passes through the cable pass-through window 11 to the upper part of the partition plate 5, and the aviation plug at the end of the cable harness is installed on the mounting slot 12 on the side wall of the cavity structure 4. Then, one end of the external connection cable harness is connected to the stepper motor 2, and the other end is connected to the aviation plug installed on the mounting slot 12. This design can effectively replace the stepper motor 2. When the stepper motor 2 is damaged, simply unplug the male and female ends connected to the aviation plug and then unscrew the fixing bolts of the stepper motor 2 to replace it, which is very convenient for maintenance.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
