Description

Technical Field

[0001] This utility model belongs to the field of unmanned aerial vehicle (UAV) equipment technology, specifically relating to a UAV button remote control device. Background Technology

[0002] With the rapid development of drone technology, its applications in surveying, inspection, logistics, and emergency rescue are becoming increasingly widespread. To achieve efficient and continuous operations, drone nests (or automated airports) have emerged, designed to enable drones to automatically take off, land, recharge, and transmit data. However, a crucial aspect of automated drone operations lies in how to remotely and automatically start the drone and its remote controller. Currently, this step typically still requires manual on-site operation, such as manually pressing the drone's power switch or the remote controller's start button. This manual intervention not only increases operational complexity and management costs but also fundamentally limits the application of drone systems in truly unattended scenarios.

[0003] To replace manual operation, some existing technologies employ servo motors to simulate human hand button pressing. These solutions control the rotation angle of the servo motor to drive a linkage or push rod, thereby triggering the remote control button. However, these servo motor simulation solutions have several inherent drawbacks: First, the control precision of servo motors is limited, making it difficult to accurately simulate the force, travel, and contact feedback of manual button pressing. Insufficient force can lead to button failure, or overshoot can cause equipment damage, resulting in poor operational reliability and consistency. Second, the mechanical structure of the servo motor itself is prone to wear and aging under prolonged, high-frequency operation, resulting in insufficient durability and reliability, affecting the long-term stable operation of the entire UAV system. Furthermore, servo motor control typically requires complex circuitry and meticulous programming and debugging, increasing system complexity and implementation and maintenance costs.

[0004] Therefore, there is an urgent need in this field for an automatic button operation device for UAV remote controllers that is precise, reliable, compact, and adaptable to long-term operation in harsh environments, in order to overcome the shortcomings of existing manual operation and servo motor simulation solutions and promote the further improvement of UAV fully automated operation technology.

Detailed Implementation

[0017] 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. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] like Figures 1 to 4 As shown, this utility model provides a drone button remote control device, including a structural part and a circuit part. The circuit part 2 is fixed inside the structural part and is encapsulated and protected by the waterproof shell 1 of the structural part. The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Specific implementation methods for the structural components: The structural components mainly include a waterproof housing 1, a heat dissipation system, and a motor mounting structure. The waterproof housing 1 features a sealed design, effectively preventing the intrusion of external media such as rainwater and dust, ensuring the reliability of the device in harsh environments. The heat dissipation system is integrated inside the waterproof housing 1 and includes a semiconductor condenser 7, an exhaust fan 4, an air duct structure 5, and a dust filter 6.

[0020] The semiconductor condenser 7 is fixedly mounted on the back of the mounting plate of the exhaust fan 4, with its cold end facing downwards towards the circuit section 2, forming a cold air outlet 11 for active heat dissipation of the circuit section 2; its hot end is opposite to the exhaust fan 4. The exhaust fan 4 uses natural ventilation, expelling the hot air generated by the semiconductor condenser 7 from the air outlet on the device panel through the air duct structure 5. A dust filter 6 is provided at the air inlet to filter dust from the intake air and prevent dust accumulation from affecting the heat dissipation effect. The cold air outlet 11 circulates cold air to the remote control, effectively reducing the ambient temperature around the remote control and preventing performance degradation due to high temperatures.

[0021] Specific implementation of the circuit section: The circuit section 2 includes a control processing module 300, a motor drive module 100, a power supply module 200, and a communication module 400. Each module is connected and fixed inside the structural section via a circuit board.

[0022] The power supply module 200 is a 12V DC power supply module with a power interface 9, used to provide a stable power supply for the entire device. Its output terminals are connected to the control processing module 300, the motor drive module 100, the communication module 400, and the semiconductor condenser 7, respectively. The control processing module 300 integrates a data processing unit and a logic control unit, serving as the core controller of the device, responsible for receiving instructions, processing data, and outputting control signals. The communication module 400 uses an RS485 bus communication interface 3 for wireless remote data communication with an external control center, enabling instruction reception and status feedback. The motor drive module 100 receives instructions from the control processing module 300 and drives the micro stepper motor 62 in the motor device.

[0023] Specific implementation method of the motor device: The motor assembly includes a motor mounting bracket 61, a miniature 12V stepper motor 62, a membrane key switch 8, and a photosensitive detection device 10. The miniature stepper motor 62 is fixedly mounted via the motor mounting bracket 61, with its output shaft aligned with the corresponding button on the drone remote controller to simulate manual button operation. The membrane key switch 8 is located at the end of the stroke of the output shaft of the miniature stepper motor 62. When the output shaft is pressed to its full position, the membrane key switch 8 is triggered, generating a signal that is fed back to the control processing module 300 to detect whether the button has been pressed. The photosensitive detection device 10 is located near the motor assembly to detect whether the miniature stepper motor 62 is operating, further increasing the reliability of status monitoring.

[0024] The working process of this utility model is as follows: The external control center sends button operation commands to the control processing module 300 via the RS485 communication module 400. After parsing the commands, the control processing module 300 drives the micro stepper motor 62 through the motor drive module 100, causing its output shaft to press the remote control button. At the same time, the membrane key switch 8 and the photosensitive detection device 10 detect the button status and motor running status in real time and feed the signals back to the control processing module 300, forming a closed-loop control to ensure the accuracy and reliability of the button operation. During the operation of the device, the heat dissipation system runs continuously: the cold air generated by the semiconductor condenser 7 cools the circuit part 2 and the remote control environment through the cold air outlet 11, the exhaust fan 4 exhausts the hot air, the dustproof net 6 prevents dust from entering, and the waterproof shell 1 provides overall protection.

[0025] In summary, this invention uses a micro stepper motor as the actuator, which offers significantly higher control precision than traditional servo motors. It accurately simulates the travel and force of a button, effectively preventing button malfunctions or equipment damage caused by inaccurate force. Furthermore, the dual detection mechanism, comprised of a membrane key switch and a photosensitive detection device, provides real-time feedback on the button's position and the motor's operating status, forming a closed-loop control that greatly improves the success rate of single operations and the overall system reliability.

[0026] By combining an active cooling system with a built-in semiconductor condenser and an exhaust fan, and supplemented by a dustproof net and waterproof shell design, the device effectively solves the problem of performance degradation or failure caused by excessive internal temperature or external media intrusion during long-term continuous operation or in harsh environments such as high temperature, dust, and humidity. This significantly improves the device's environmental adaptability and long-term operational stability and durability.

[0027] The circuitry employs a modular design. The control processing module integrates data processing and logic control functions, while the communication module uses a standard RS485 bus interface. This results in a compact structure, simple wiring, and easy integration into existing UAV nest control systems. This modular and standardized design not only reduces system complexity and maintenance costs but also ensures the accuracy of command transmission and execution, as well as the stability of the entire control process.

[0028] This invention completely replaces manual intervention in the drone startup process and overcomes the shortcomings of insufficient reliability in existing servo motor solutions. Through seamless integration with the drone's nest system, it can remotely, automatically, and reliably complete remote control button operations, which is a key technical guarantee for realizing "unmanned" duty and fully automated operation processes for drones.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
