Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically a power steering device for UAVs. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control equipment and their own program control devices. UAVs are actually a general term for unmanned aircraft, which can be defined from a technical point of view as: unmanned fixed-wing aircraft, unmanned vertical take-off and landing aircraft, unmanned airships, unmanned helicopters, unmanned multi-rotor aircraft, unmanned paragliders, etc.

[0003] Chinese utility model patent CN221699059U, published on September 13, 2024, discloses a power steering device for unmanned aerial vehicles (UAVs). It includes a servo motor, a first drive motor, a transmission assembly connected to the servo motor and the first drive motor for rotating the first drive motor relative to the servo motor under the drive of the servo motor, and a propeller connected to the first drive motor for rotating under the drive of the first drive motor. The transmission assembly includes a connecting frame. This utility model's power steering device for UAVs, with its reasonable structural design, low maintenance cost, and high stability during operation, is suitable for UAV applications.

[0004] However, the aforementioned publicly available solutions have the following shortcomings: Existing drone power steering devices achieve a compact design, but cannot be adapted to different sizes of servos, nor can they be adapted to the steering requirements of drones and propellers of different sizes and weights to achieve the steering function. Utility Model Content

[0005] The purpose of this invention is to solve the technical problem that existing drone power steering devices, while achieving a compact design, cannot be adapted to different sizes of servos or to the steering requirements of drones and propellers of different sizes and weights, thus failing to achieve the steering function. This invention provides a drone power steering device.

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

[0007] The present invention discloses a power steering device for unmanned aerial vehicles (UAVs), comprising a servo motor; a fixed frame is sleeved on the servo motor; a stepped plate is inserted into the fixed frame through an opening; the stepped plate is fixedly connected to the servo motor; a plurality of first fasteners are threadedly connected to the stepped plate through an opening; a motor mounting bracket is sleeved on the first fasteners; a plurality of second fasteners are threadedly connected to the fixed frame through an opening; and an external bracket is sleeved on the second fasteners.

[0008] Furthermore, a detachable clamping bracket is fixedly attached to the external frame; a drone connecting shaft is inserted into the clamping bracket.

[0009] Furthermore, a brushless motor is detachably fixed to the motor mounting bracket; a fan blade is sleeved on the output shaft of the brushless motor, and a fastening cap is threaded onto it.

[0010] Furthermore, the motor mounting bracket is provided with multiple weight-reducing grooves.

[0011] Furthermore, the fixing frame is manufactured by bending sheet metal.

[0012] Furthermore, the drone connecting shaft and the ferrule holder have a third fastener threaded into the hole.

[0013] The power steering device for unmanned aerial vehicles provided by this utility model has the following beneficial effects:

[0014] 1. This utility model can be connected and fixed to the drone via an external frame, thus adapting to drones of different sizes. By designing a fixed frame larger than the servo motor and fixing a drive step plate to one side of the servo motor, it can accommodate servo motors of different sizes, thereby meeting the power steering requirements of drones of different sizes. Furthermore, the motor mounting bracket rotates the brushless motor 90 degrees, avoiding inertial interference caused by the overall rotation of the cabin. Moreover, by using lightweight materials to manufacture the structure of this device, the overall weight of the drone can be reduced, thereby effectively increasing the payload.

[0015] 2. This utility model makes it easier to connect and fix the drone's connecting shaft through the clamp bracket, while also reducing the resistance between the fan blades and the steering device when the fan blades are in a horizontal state, effectively preserving the lift from the fan blades; the brushless motor provides lift by rotating the fan blades when powered, thereby propelling the drone forward or upward.

[0021] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0022] 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 a part of the embodiments of this utility model, and not all of them. 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.

[0023] It should be noted that all directional indications (such as up-down-left-right-forward-backward...) in the embodiments of this utility model are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly. The connection can be a direct connection or an indirect connection.

[0024] Please see Figure 1-3 As shown, a power steering device for an unmanned aerial vehicle (UAV) includes a servo motor 1 as a drive structure; a metal mounting frame 2 is fitted onto the servo motor 1; a stepped plate 3 is inserted into an opening in the mounting frame 2; the stepped plate 3 is fixedly connected to the servo motor 1 and rotates with the servo motor 1; multiple first fasteners 4 are threaded onto an opening in the stepped plate 3; a motor mounting bracket 5 is fitted onto the first fasteners 4, thereby causing the motor mounting bracket 5 to rotate 90 degrees with the servo motor 1; multiple second fasteners 9 are threaded onto an opening in the mounting frame 2; an external bracket 1 is fitted onto the second fasteners 9. The device can be connected and fixed to the drone via the external bracket 10, thus adapting to drones of different sizes. By designing the fixed frame 2 to be larger than the servo motor 1 and fixing the drive step plate 3 to one side of the servo motor 1, it can adapt to servo motors of different sizes, thereby meeting the power steering needs of drones of different sizes. The motor mounting bracket 5 rotates the brushless motor 6 ninety degrees, avoiding inertial interference caused by the overall rotation of the cabin. Furthermore, by manufacturing the structure of this device with lightweight materials, the overall weight of the drone can be reduced, thereby effectively increasing the payload.

[0025] A retaining bracket 11 is detachably fixed to the external frame 10; a drone connecting shaft 13 is inserted into the retaining bracket 11. The retaining bracket 11 makes it easier to connect and fix the drone connecting shaft 13, and at the same time, when the fan blade 7 is in a horizontal state, the resistance of this steering device is small, which can effectively preserve the lift from the fan blade 7.

[0026] A brushless motor 6 is detachably fixed to the motor mounting bracket 5; a fan blade 7 is sleeved on the output shaft of the brushless motor 6, and a fastening cap 8 is threaded on it. When the brushless motor 6 is powered, it drives the fan blade 7 to rotate, providing lift, which can propel the drone forward or upward.

[0027] The motor mounting bracket 5 has multiple weight-reducing slots 14, which reduce the weight of the motor mounting bracket 5, thereby further improving the drone's endurance without changing the structural strength of the motor mounting bracket 5.

[0028] The fixed frame 2 is made by bending sheet metal, which makes the fixed frame 2 structurally strong and can stably support the servo motor 1 and the brushless motor 6.

[0029] The drone connecting shaft 13 and the ferrule holder 11 are threaded with a third fastener 12. The third fastener 12 makes the connection between the drone connecting shaft 13 and the ferrule holder 11 more stable and secure, so that it will not fall off and be damaged during high-speed operation and vibration, and can be adapted to drones of different sizes and positions.
