Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) remote control equipment technology, and in particular to a UAV voice control device. Background Technology

[0002] Unmanned aerial vehicle (UAV) voice control equipment is a UAV control device that integrates voice interaction functions. It enables the control of key parameters such as the flight attitude and operation mode of the UAV through voice commands and is widely used in scenarios such as agricultural plant protection, power line inspection, and emergency rescue.

[0003] Common drone voice control devices typically consist of a remote controller body, control components, an interaction module, and a voice acquisition unit. The remote controller body integrates control circuitry and a communication module. The joystick and control ball are used to precisely adjust the drone's flight direction and altitude. The display screen and indicator lights provide real-time feedback on the drone's status and command execution. The voice microphone is responsible for collecting user voice commands to achieve contactless control and ensure stability during operation.

[0004] However, the microphones of existing devices are mostly fixed or have a simple folding structure. After the angle is adjusted, they lack a reliable locking mechanism and are prone to displacement due to vibration or accidental touch. In addition, they are inconvenient to store after use and take up a lot of space. Furthermore, the handles are mostly fixedly connected to the main body of the remote control, and cannot be flexibly disassembled according to the user's hand shape or usage scenario, resulting in poor adaptability. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a voice control device for drones, which aims to improve the problems of unreliable locking after adjusting the microphone angle, inconvenient storage after use, and poor adaptability of the handle that cannot be flexibly disassembled and assembled according to the user's hand shape or usage scenario in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A voice control device for unmanned aerial vehicles includes a remote controller. A display screen is mounted on the top of the remote controller. A rotating base is rotatably connected inside the remote controller. A voice microphone is mounted on the outside of the rotating base. Rotating rods are fixedly connected to both the front and rear ends of the rotating base. A locking component is provided on the rear side inside the remote controller.

[0008] The locking assembly includes a threaded rod that is threadedly connected to the rear side of the inside of the remote control. A limit block is fixedly connected to the front end of the threaded rod, and a knob is fixedly connected to the rear end of the threaded rod.

[0009] As a further description of the above technical solution:

[0010] The remote control has mounting bases fixedly connected to the left and right sides of its bottom. Mounting blocks are slidably connected inside the mounting bases. A grip handle is fixedly connected to the bottom of the mounting blocks. Limit plates are slidably connected to the left and right sides of the bottom of the remote control. Multiple evenly distributed compression springs are fixedly connected to the top of the limit plates.

[0011] As a further description of the above technical solution:

[0012] The limiting plate abuts against the front side of the mounting block, and the other end of the compression spring is fixedly connected to the inside of the remote control.

[0013] As a further description of the above technical solution:

[0014] The mounting base has an internal mounting slot, and the mounting block is slidably connected within the mounting slot;

[0015] As a further description of the above technical solution:

[0016] The remote control has a control ball installed on the top left side, an operation joystick installed on the top right side, and two indicator lights installed on the top of the remote control.

[0017] As a further description of the above technical solution:

[0018] The remote control has a storage slot on its top, and the rotating base is rotatably connected to the left side of the storage slot.

[0019] As a further description of the above technical solution:

[0020] The remote control has a limiting hole on the left rear side. The limiting hole is based on the principle that one side of the rotating rod is threaded and the other side is smooth. The threaded rod is threadedly connected in the limiting hole, and the limiting block is slidably connected in the limiting hole.

[0021] As a further description of the above technical solution:

[0022] The limiting block abuts against the outside of the rear rotating rod, and the knob abuts against the rear of the remote control.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the voice microphone is rotated to the required angle by rotating the base. Then, the knob is turned so that the threaded rod pushes the limiting block to press against the rotating rod of the rotating base. With the help of the self-locking property of the threaded connection and the abutting action of the limiting block, the voice microphone is effectively prevented from shifting due to vibration or accidental touch, ensuring stable sound pickup accuracy. After use, the rotating base and the voice microphone can be rotated into the storage slot, which greatly reduces the storage space occupied and solves the storage problem of traditional fixed or simple folding voice microphones.

[0025] 2. In this utility model, by sliding the mounting block into the mounting slot of the mounting base, the limiting plate will automatically press against the mounting block under the elastic force of the compression spring, completing the quick positioning and locking of the handle. When disassembling, simply push the limiting plate to compress the spring, and the mounting block can be removed from the mounting slot. This allows users to flexibly choose whether to install a handle or replace it with a handle of different specifications according to their own hand shape or usage scenario, significantly improving the adaptability and comfort of the device, and solving the adaptability limitations of traditional fixed connection grip handles.

[0034] 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.

[0035] Reference Figures 1-6 This utility model provides an embodiment of a drone voice control device, including a remote controller 1. The remote controller 1 integrates all control components, an interaction module, and a control circuit, serving as the basic carrier for realizing both voice control and manual operation of the drone. A control ball 2 is mounted on the top left side of the remote controller 1. The control ball 2 allows for precise adjustment of the drone's horizontal flight attitude through scrolling. An operation joystick 3 is mounted on the top right side of the remote controller 1. The joystick 3 controls the drone's ascent and descent by moving it forward and backward, and controls its forward and backward flight by moving it left and right. Two indicator lights 4 are mounted on the top of the remote controller 1, each serving a different status indication function: one indicates the drone's power and communication status, and the other indicates the command reception status. A display screen 5 is mounted on the top of the remote controller 1. The display screen 5 serves as an information interaction window, displaying key flight parameters of the drone in real time, including flight altitude, flight speed, remaining battery power, and current position coordinates. It can also display the recognition results and execution progress of voice commands. The remote control 1 has an internal rotating base 8, which serves as the mounting and angle adjustment carrier for the microphone 7. This allows the microphone 7 to adjust its pickup direction to accommodate different users' speaking postures or the location of the sound source in different scenarios. The microphone 7 is mounted on the outside of the rotating base 8. The microphone 7 converts sound signals into electrical signals and transmits them to the control module inside the remote control 1 to complete the recognition and execution of voice commands, reducing the frequency of manual operation by the user. The top of the remote control 1 has a storage slot 6, which is a dedicated storage space designed for the rotating base 8 and the microphone 7. The rotating base 8 is rotatably connected to the left side of the storage slot 6, allowing the rotating base 8 and the microphone 7 to be rotated into the storage slot 6. This not only prevents the microphone 7 from being exposed to collisions or dust, but also reduces the space occupied by the remote control 1 when it is stored, making it convenient to put into a backpack or toolbox for carrying. The rotating base 8 has rotating rods 9 fixedly connected to both the front and rear ends. The rotating rods 9 serve as both rotational support and locking force. The remote control 1 has a locking component on the rear side inside.

[0036] The locking assembly includes a threaded rod 10, which is threadedly connected to the rear side of the remote control 1. A limit block 11 is fixedly connected to the front end of the threaded rod 10, and the limit block 11 abuts against the outer side of the rear rotating rod 9. The threaded rod 10 can convert the rotational motion of the user's knob 13 into forward and backward linear motion, thereby pushing the limit block 11 closer to or away from the rotating rod 9. Through the tight abutment of the limit block 11 against the rear rotating rod 9, the rotation of the rotating rod 9 is directly restricted, thereby fixing the angle of the rotating base 8. A limit hole 12 is opened on the left side of the rear of the remote control 1. The limit hole 12 is threaded on one side of the rotating rod 9. The other side is smooth. The threaded rod 10 is threadedly connected to the limiting hole 12, and the limiting block 11 is slidably connected to the limiting hole 12. The limiting hole 12 provides installation and movement space for the threaded rod 10 and the limiting block 11. Its inner side is divided into two sections, which can guide the transmission of the threaded rod 10 and the sliding of the limiting block 11 respectively. The rear end of the threaded rod 10 is fixedly connected to a knob 13. The knob 13 abuts against the rear side of the remote control 1. The knob 13 is a hand contact part for the user to operate the locking component, preventing the knob 13 from falling into the remote control 1 due to excessive pushing when the threaded rod 10 moves forward.

[0037] Reference Figures 1-4 The remote control 1 has mounting bases 14 fixedly connected to both the left and right sides of its bottom. The mounting bases 14 can withstand the pulling and pressure during use of the handle 17, providing a stable mounting foundation and ensuring that the handle 17 does not wobble after installation. Mounting blocks 15 are slidably connected inside the mounting bases 14, and mounting slots 16 are provided inside the mounting bases 14. The mounting blocks 15 are slidably connected within the mounting slots 16, precisely matching the mounting blocks 15 and the mounting slots 16 inside the mounting bases 14. This sliding method allows for quick assembly. Compared to traditional screw connections, installation and disassembly can be completed without tools, significantly improving the efficiency of replacing the handle 17 and allowing users to flexibly adjust it according to their needs. A grip handle 17 is fixedly connected to the bottom. The grip handle 17 can reduce hand fatigue when the user operates the remote control 1 for a long time. At the same time, the user can choose whether to install the grip handle 17 according to their own hand shape, or replace the grip handle 17 with one of different lengths and thicknesses to improve the adaptability of the device. Limiting plates 18 are slidably connected to the left and right sides of the bottom of the remote control 1. The limiting plates 18 abut against the front of the mounting block 15. The limiting plates 18 are locking components to prevent the mounting block 15 from sliding on its own. Multiple evenly distributed compression springs 19 are fixedly connected to the top of the limiting plates 18. The other end of the compression springs 19 is fixedly connected to the inside of the remote control 1. The compression springs 19 provide continuous elastic pressure to the limiting plates 18 to prevent the limiting plates 18 from tilting due to uneven force.

[0038] Working principle: Before using the voice control function, the user needs to rotate the rotating base 8 in the storage slot 6 outward. The rotating base 8 rotates smoothly through the cooperation of the rotating rod 9 and the inside of the remote control 1, which simultaneously drives the outer microphone 7 to adjust its angle until the microphone 7 is pointed in the direction of the user's speech. After the angle adjustment is completed, the user rotates the knob 13 on the back of the remote control 1 clockwise. The threaded rod 10 moves forward in the threaded section of the limiting hole 12. The limiting block 11 at the front end of the threaded rod 10 slides along the smooth section of the limiting hole 12. Finally, the limiting block 11 tightly abuts against the outside of the rear rotating rod 9. The self-locking property of the threaded connection and the clamping force of the limiting block 11 restrict the rotation of the rotating rod 9, thereby fixing the angle between the rotating base 8 and the microphone 7. When the voice control function is finished, the user rotates the knob 13 counterclockwise. The threaded rod 10 drives the limiting block 11 to retract, releasing the clamping force on the rotating rod 9. Then, the rotating base 8 is rotated back into the storage slot 6, completing the storage and protection of the microphone 7.

[0039] When the grip handle 17 needs to be installed to improve grip comfort, the user first aligns the mounting block 15 at the top of the grip handle 17 with the mounting slot 16 of the mounting base 14 at the bottom of the remote control 1. Then, the user pushes the grip handle 17 inward. As the mounting block 15 slides along the mounting slot 16, it will squeeze the limiting plate 18. The limiting plate 18 slides upward and compresses the compression spring 19 at the top. After the mounting block 15 is completely slid into the mounting slot 16, the compression spring 19 loses its compression and releases its elastic force, pushing the limiting plate 18 downward to reset. The limiting plate 18 finally abuts against the front of the mounting block 15, restricting the sliding of the mounting block 15 and locking the grip handle 17. If the grip handle 17 needs to be removed, the user only needs to push the limiting plate 18 upward. The compression spring 19 will compress again, and the limiting plate 18 will disengage from the mounting block 15. At this time, the user can pull the grip handle 17 outward to remove the mounting block 15 from the mounting slot 16, completing the removal.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
