Description

Technical Field

[0001] This utility model relates to the field of police drone technology, and in particular to a heavy-load police drone. Background Technology

[0002] With the increasing application of police drones in various fields, the demand for high-speed, high-payload drones is growing stronger, especially in application scenarios such as vehicle pursuit and interception, where high-payload police drones need to have sufficient payload capacity and flight speed.

[0003] However, there are currently no drones on the market that can simultaneously meet the requirements of large payload and high speed. Taking heavy-duty transport drones and racing drones as examples, transport drones have a strong payload capacity but a slow flight speed, while racing drones have a high speed but a poor payload capacity. At the same time, most existing police drones carry goods by strapping the items to the drone. Because the drone flies at high speeds, it will produce some significant shaking. If the items are not securely strapped, they are very likely to fall off. In addition, the strapping operation is cumbersome and time-consuming, which is not conducive to user operation. Therefore, this application discloses a structure for a heavy-duty police drone to meet the needs of special scenarios. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a heavy-duty police drone to solve the aforementioned problems.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A heavy-duty police drone includes a drone body, a battery pack on the top of the drone body, a gimbal camera assembly on the outside of the drone body, a support frame fixedly connected to the bottom of the drone body, two symmetrically distributed crossbars fixedly connected to the outside of the support frame, a housing fixedly connected to the bottom of the two crossbars, a moving component inside the housing, a sliding component at the bottom of the housing, and two symmetrically distributed clamps at the bottom of the housing, the clamps being L-shaped.

[0007] Preferably, the gimbal camera assembly includes a camera disposed on one side of the drone body, and a single-axis gimbal is disposed at the bottom of the drone body.

[0008] Preferably, the drone body has folding structures at all four corners, and one side of each folding structure has a wing carbon rod.

[0009] Preferably, an electronic speed control plate is provided on one side of each of the four wing carbon rods, and a motor is provided at the top and bottom of the electronic speed control plate. The output end of the motor is fixedly connected to multiple blades distributed in a circular pattern.

[0010] Preferably, the movable component includes a rotating shaft rotatably connected to one side of the housing, the rotating shaft extending into the interior of the housing, one end of the rotating shaft being fixedly connected to a bidirectional screw, and the exterior of the bidirectional screw being threadedly connected to a threaded sleeve.

[0011] Preferably, the sliding assembly includes a groove formed at the bottom of the housing, and sliders are fixedly connected to the bottom of both threaded sleeves, the sliders being slidably connected inside the groove.

[0012] Preferably, a handle is fixedly connected to one side of the rotating shaft, and the handle is made of rubber.

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows: by adopting a multi-propeller power structure, flight stability is improved; by using a gimbal camera component, the clarity and stability of the captured view are enhanced; and by using two symmetrically distributed movable clamps, the transported items can be secured. These structures improve the flight stability and load-bearing capacity of the drone body, while also providing simple and secure securing of transported items. This avoids the drawbacks of traditional methods that involve tying items to the drone body with ropes, which are cumbersome and time-consuming due to the high speed and significant swaying of the drone during flight. This significantly simplifies the process for operators. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: Refer to Figure 1-4 A heavy-duty police drone includes a main body 1, a battery pack 2 on the top of the main body 1, and a gimbal camera assembly on the outside of the main body 1. The gimbal camera assembly includes a camera 9 on one side of the main body 1 and a single-axis gimbal 8 on the bottom of the main body 1. The gimbal camera assembly improves the clarity and stability of the captured image. Folding structures 10 are located at each of the four corners of the main body 1. A wing carbon rod 3 is located on one side of each of the folding structures 10. An electronic speed control plate 4 is located on one side of each of the four wing carbon rods 3. Motors 5 are located at the top and bottom of the electronic speed control plate 4. Multiple circumferentially distributed propeller blades 6 are fixedly connected to the output end of each motor 5.

[0021] Specifically, a support frame 7 is fixedly connected to the bottom of the drone body 1. Two symmetrically distributed crossbars 11 are fixedly connected to the outside of the support frame 7. A housing 12 is fixedly connected to the bottom of the two crossbars 11. A moving component is provided inside the housing 12. The moving component includes a rotating shaft 13 rotatably connected to one side of the housing 12. The rotating shaft 13 extends into the inside of the housing 12. A bidirectional screw 15 is fixedly connected to one end of the rotating shaft 13. Threaded sleeves 16 are threadedly connected to the outside of the bidirectional screw 15. Through the moving component, the two clamping plates 19 can move in opposite directions.

[0022] Specifically, a sliding assembly is provided at the bottom of the housing 12. The sliding assembly includes a groove 18 formed at the bottom of the housing 12. The bottoms of the two threaded sleeves 16 are fixedly connected to sliders 17, which are slidably connected inside the groove 18. By sliding the sliders 17 inside the groove 18, the threaded sleeves 16 will not rotate when moving. The bottom of the housing 12 is provided with two symmetrically distributed clamps 19, which are L-shaped. A handle 14 is fixedly connected to one side of the pivot 13. The handle 14 is made of rubber. The rubber handle 14 improves the comfort of the operator when holding the handle 14.

[0023] In use: This device employs a multi-rotor propulsion structure, with carbon rotors 3 extending from the left front, right front, left rear, and right rear of the fuselage. Each rotor 3 has blades 6 mounted above and below it. Based on UAV dynamics and aerodynamics, the upper and lower rotor blades 6 are kept 14cm apart, and the rotor structure with completely opposite rotation directions effectively counteracts the anti-torque, maintaining flight stability. Through a separate electronic speed controller (ESC) plate 4 and motor 5, the payload capacity is effectively improved. Furthermore, through an embedded structural design, the ESC plate is fixed to the left and right sides of the carbon rotors 3 below the motor 5, increasing heat dissipation and reducing short-circuit current. The increased distance ensures signal stability, significantly improving reliability. Simultaneously, the reduced workload on individual ESC boards 4 and motors 5 reduces heat generation and lightens the load on the rotor circuitry. Placing the ESC connection wires of motor 5 in the middle of the hollow carbon rod reduces short-circuit risk and optimizes heat dissipation for motor 5 and the rotor shaft. Furthermore, mounting a camera 9 and image transmission system at the front of the fuselage, with a single-axis gimbal 8 fixed below the camera 9, improves the clarity and stability of the captured image. This allows pilots to quickly assess complex flight conditions and adjust flight strategies, greatly enhancing aircraft safety. By fixing the battery pack 2 to the top of the fuselage, the power is connected to the fuselage through the power distribution board and multi-port converter, meeting the power requirements of heavy aircraft, reducing the consumption and complexity of large power supplies, and making the maintenance of the whole aircraft more convenient and quick. Items are placed between the two clamping plates 19. By gripping and rotating the handle 14, the rotating shaft 13 and the bidirectional screw 15 are rotated, causing the two symmetrically distributed threaded sleeves 16, sliders 17, and clamping plates 19 to move in opposite directions. At this time, the clamping plates 19 can clamp and fix the item. The sliders 17 are slidably connected to the inside of the slide groove 18, thus allowing... The threaded sleeve 16 will not rotate during movement. Through the above structure, the flight stability and load-bearing capacity of the drone body 1 can be improved. At the same time, the transported items can be fixed. The fixing operation is relatively simple and the firmness is high. It avoids the disadvantages of using ropes to tie items to the drone body 1 in the traditional way. Since the drone flies at a high speed, it will produce some large swaying. If it is not tied firmly, the items are very easy to fall off. At the same time, the binding operation is more cumbersome and time-consuming. It greatly facilitates the use of the staff.
