Description

Technical Field

[0001] This utility model relates to the field of drone application technology, and in particular to an adjustable-angle drone throwing device. Background Technology

[0002] Drone delivery devices are widely used in logistics, emergency rescue, and environmental monitoring, with the core requirement being the precise and flexible delivery of materials. Existing drone delivery devices mostly employ fixed delivery structures, with the delivery direction determined by the drone's flight attitude and unable to be independently adjusted, resulting in delivery accuracy being significantly affected by flight stability. Some adjustable-angle delivery devices require disassembly on the ground or adjustment via complex mechanical structures, making operation cumbersome and unable to quickly adapt to different delivery needs during drone flight. Furthermore, the limited angle adjustment range of existing devices makes it difficult to meet the delivery angle requirements of different scenarios, reducing the device's versatility and practicality. Therefore, a new drone delivery device is urgently needed to address the problems of insufficient flexibility and inconvenient operation in existing technologies. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned technical deficiencies and propose an adjustable-angle drone throwing device to solve the problems mentioned in the background art.

[0004] To achieve the above technical objectives, the present invention provides an adjustable-angle drone throwing device, comprising a housing, the housing being an inverted U-shape with baffles at both ends, the upper end of the baffles being rotatably connected to the inner wall of the housing, and the lower end being provided with a bracket, a self-resetting pin being provided at the lower part of the baffles, a retaining plate and an actuator being provided on the outer wall of the housing, one end of the retaining plate being rotatably connected to the housing and driven by the actuator, the pin of the self-resetting pin passing through the outer wall of the housing and engaging with the other end of the retaining plate, the two ends of the bracket being hinged to the baffles via the pin of the self-resetting pin, and an opening / closing angle adjustment mechanism being provided between the bracket and the housing.

[0005] Furthermore, the bracket includes two end rods, with a sliding plate and a stabilizing rod disposed between the two end rods. Two stabilizing rods are respectively disposed on both sides of the sliding plate, and both ends of the stabilizing rods are fixedly connected to the two end rods. The two ends of each end rod are provided with hinge sleeves, one end of which is rotatably connected to the end rod, and the other end is provided with a through hole that mates with the pin of the self-resetting pin.

[0006] Furthermore, the opening and closing angle adjustment mechanism includes a limiting plate and a limiting rod.

Detailed Implementation

[0011] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0012] Reference Figure 1 This utility model provides an adjustable-angle drone throwing device, including a housing 1, a baffle 2, and a bracket 3. The housing 1 is an inverted U-shape, with the baffle 2 fitted at both ends. The upper end of the baffle 2 is rotatably connected to the inner wall of the housing 1 via a hinge. The baffle 2 can be flipped open and closed around the connection point. The lower end of the baffle 2 cooperates with the bracket 3, which carries the material to be thrown. The overall structure is fixed to the drone body through the housing 1, providing an installation reference and protection for each component.

[0013] Reference Figure 2A self-resetting pin 4 is fixedly installed at the lower part of the baffle 2. The self-resetting pin 4 has a built-in reset spring. Its pin passes through the side wall of the housing 1 in a horizontal direction, and a slot is opened on the part of the pin located outside the housing 1. A retaining plate 101 and an actuator are installed on the outer wall of the housing 1 corresponding to the pin position. The actuator is preferably an electromagnetic push rod or a servo motor and is connected to the UAV remote control system. One end of the retaining plate 101 is rotatably connected to the outer wall of the housing 1 through a rotating shaft, and the other end is provided with an arc-shaped positioning groove that matches the pin slot.

[0014] Reference Figure 3 The bracket 3 consists of two parallel end rods 301, a sliding plate 302, and two stabilizing rods 303. The two stabilizing rods 303 are located on both sides of the sliding plate 302, and both ends of the stabilizing rods 303 are connected and fixed to the two end rods 301 to form a stable load-bearing frame. Hinged sleeves 304 are fitted onto both ends of the end rods 301. One end of the hinged sleeve 304 is rotatably connected to the end rod 301, and the other end has a through hole. (Refer to...) Figure 1 Under normal conditions, the hinge sleeve 304 is located between the reset pin 4 and the housing 1. The pin passes through the through hole of the hinge sleeve 304, allowing the bracket 3 to rotate flexibly around the self-resetting pin 4. A limit plate 102 is installed on the inner wall of the housing 1. The limit plate 102 has an L-shaped structure. One side of the plate is fixed to the housing 1 by bolts, and the other side has a strip-shaped sliding hole along its length. A limit rod 305 is fixedly installed on the stabilizing rod 303 of the bracket 3. The other end of the limit rod 305 passes through the strip-shaped sliding hole and is screwed with a limit nut.

[0015] To facilitate understanding of this utility model, the following is combined with... Figure 1 - Figure 3 The working principle of this solution will be explained in detail: Under normal conditions, the self-resetting pin 4 remains extended, and the positioning groove and the slot are tightly engaged. The mechanical limit locks the baffle 2 and the bracket 3, and the goods are placed in the enclosed space composed of the housing 1, the baffle 2, and the bracket 3. When throwing is required, the operator sends an unlocking signal via remote control. After receiving the signal, the actuator drives the bracket 101 to rotate around the pivot, the positioning groove disengages from the slot, and the self-resetting pin 4 retracts under the tension of the reset spring. After the baffle 2 and the bracket 3 lose their limit, they flip downwards and open under their own weight and the pressure of the material to be thrown, around the self-resetting pin 4 at the other end. The goods slide along the bracket 3 under the action of gravity and are released from the housing 1 to complete the throwing action. According to actual needs, the actuator can be used to select to open the bracket 101 on either side of the housing 1, thereby achieving controllable throwing direction.

[0016] When the bracket 3 rotates, the limiting rod 305 slides along the strip-shaped sliding hole and moves downwards. After the limiting nut contacts the limiting plate 102, it restricts the bracket 3 from continuing to rotate. By changing the position of the limiting nut on the limiting rod 305, the range of rotation of the bracket 3 can be adjusted, thereby realizing the adjustment of the throwing angle. At the same time, in order to achieve smooth throwing, several balls are embedded in the side of the sliding plate 302 facing the inside of the housing 1 to reduce the resistance of the material sliding during throwing and ensure that the material can slide out smoothly after the baffle 2 is opened.

[0017] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
