Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, specifically to a servo mounting bracket for a UAV and the UAV itself. Background Technology

[0002] A servo motor is a servo drive used for position or angle adjustment, and it is widely used in aircraft, remote-controlled robots, automobiles and other fields.

[0003] Specifically, when servos are used in UAVs, they control the rocker arm and linkage to move the control surfaces, thereby adjusting the UAV's flight attitude, direction, and altitude. In existing technology, when installing servos, the servo is first fixed to a servo bracket, and then the servo bracket is fixed to the wing ribs.

[0004] However, this type of structure has the following drawbacks in practical applications: First, the servo bracket is fixed to the wing ribs with fasteners. In this direct connection installation method, the corresponding connection points on the ribs are subject to high stress, which poses a risk of structural failure after prolonged use, affecting flight safety and leading to flight safety risks. Second, each servo bracket has only one mounting position. When the number of control surfaces increases, the number of servo brackets also needs to increase accordingly, leading to an increase in the number of components in multi-control surface application scenarios. This not only increases the workload of maintenance personnel but also makes it difficult to further optimize the overall aircraft weight. Summary of the Invention

[0005] The purpose of this utility model is to provide a servo mounting bracket for unmanned aerial vehicles (UAVs) and the UAV itself, so as to solve the technical problems of existing servo brackets having high stress at the connection points, which can easily lead to flight risks, and having many parts and difficulty in optimizing the overall weight of the aircraft in multi-control surface scenarios.

[0006] To achieve the above objectives, the present invention proposes the following technical solution: In the first aspect, this technical solution provides a servo mounting bracket for a drone, including a rectangular sleeve, an L-shaped fixing plate, and several U-shaped mounting plates that cooperate with each other; the L-shaped fixing plate includes a first side plate and a second side plate that are perpendicular to each other, and the U-shaped mounting plate has a mounting hole in the middle and a flange that extends vertically outward along the two empty ends. The rectangular sleeve is fixed to the rudder support rod. The first side plate of the L-shaped fixing plate is fixed to the upper side of the rectangular sleeve, and the second side plate is fixed to the wing spars. Each U-shaped mounting plate is fixed to both sides of the rectangular sleeve by corresponding flanges. Each servo is installed at the mounting hole of each U-shaped mounting plate.

[0007] Furthermore, the rectangular sleeve includes an upper U-shaped plate, a lower U-shaped plate, a left side plate, and a right side plate that cooperate with each other; the left side plate is fixed to the left end face of the upper U-shaped plate and the lower U-shaped plate, and the right side plate is fixed to the right end face of the upper U-shaped plate and the lower U-shaped plate; wherein, the rudder surface support rod is fixed to the lower U-shaped plate.

[0008] Furthermore, the rectangular sleeve is detachably fixed to the rudder surface support rod, the L-shaped fixing plate, and each U-shaped mounting plate.

[0009] Furthermore, each side of the rectangular sleeve is provided with a first fixing hole, and the corresponding positions of the rudder support rod, the L-shaped fixing plate and each U-shaped mounting plate are provided with a second fixing hole; wherein, each fixing component is simultaneously inserted and fixed in the corresponding first fixing hole and second fixing hole.

[0010] Furthermore, the unused end of the rudder strut passes through the skin and is movably connected to the rudder.

[0011] Furthermore, the rectangular sleeve, the rudder surface strut, the L-shaped fixing plate, and each U-shaped mounting plate are all made of lightweight metal or lightweight alloy.

[0012] Furthermore, all surfaces of the rectangular sleeve, the rudder support rod, the L-shaped fixing plate, and each U-shaped mounting plate are smooth surfaces.

[0013] Furthermore, the rectangular sleeve, the rudder support rod, the L-shaped fixing plate, and each U-shaped mounting plate are coated with a waterproof coating.

[0014] Secondly, this technical solution provides a drone, including the aforementioned servo mounting bracket.

[0015] Furthermore, it includes a rocker arm and a connecting rod; the actuator of the servo is fixedly installed in the corresponding mounting hole; one end of the rocker arm is fixedly engaged with the actuator, and the other end is rotatably engaged with the connecting rod; the free end of the connecting rod is rotatably engaged with the arc-shaped rudder angle of the rudder surface.

[0016] Beneficial effects: This technical solution provides a servo mounting bracket for UAVs, which simultaneously solves the technical defects of existing servo brackets, such as the high risk of connection structure failure during long-term use, and the large number of structural parts and difficulty in reducing the overall weight in multi-control surface scenarios.

[0017] The mounting bracket includes a rectangular sleeve, an L-shaped fixing plate, and several U-shaped mounting plates that cooperate with each other. The L-shaped fixing plate includes a first side plate and a second side plate that are perpendicular to each other. The U-shaped mounting plates have mounting holes in the middle and flanges that extend vertically outward along the two empty ends. The rectangular sleeve is fitted and fixed to the rudder support rod.

Each U-shaped mounting plate is fixed to both sides of the rectangular sleeve by corresponding flanges. Each servo is installed at the mounting hole of each U-shaped mounting plate.

[0018] Therefore, the mounting bracket described in this technical solution achieves simultaneous and fixed connection between the bracket as a whole and the wing spars and control surface struts through the mediation of the rectangular sleeve. This provides more connection points, ensuring the installation strength of the bracket, preventing structural fatigue caused by long-term use, and improving flight safety. Simultaneously, the U-shaped mounting plates on both sides of the rectangular sleeve create two mounting positions, reducing maintenance points for aircraft personnel, increasing aircraft maintenance efficiency, reducing the number of structural parts, and lightening the overall weight of the aircraft.

Detailed Implementation

[0023] 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, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model. Unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by those skilled in the art to which this utility model pertains.

[0025] Electric servo control is a common control solution for unmanned aerial vehicles (UAVs). By controlling the rotation angle of the servo via a controller, the deflection angle of the control surfaces is adjusted, thereby controlling the UAV's pitch, yaw, and roll maneuvers during flight. Existing common servo mounting methods involve fasteners to the fuselage ribs, resulting in high stress at the connection points, a simple structure, and potential flight safety risks. Furthermore, commercially available UAV servo mounting brackets can only accommodate one servo at a time. When the number of control surfaces is greater than or equal to two, an additional number of mounting brackets are required, increasing the workload for maintenance personnel, the number of components on the UAV, and its weight. Therefore, this embodiment aims to provide a servo mounting bracket for UAVs that simultaneously solves the aforementioned technical problems.

[0026] The following detailed description of the servo mounting bracket for unmanned aerial vehicles (UAVs) disclosed in this utility model, with reference to the embodiments shown in the accompanying drawings, will be provided in further detail.

[0027] Combination Figures 1 to 2 As shown, the mounting bracket includes a rectangular sleeve 2, an L-shaped fixing plate 1, and several U-shaped mounting plates 3 that cooperate with each other. In terms of specific structural settings, the L-shaped fixing plate 1 includes a first side plate and a second side plate that are perpendicular to each other. The U-shaped mounting plates 3 have mounting holes 3.1 in the middle and flanges that extend vertically outward along the two empty ends.

[0028] In the corresponding connection relationship, the rectangular sleeve 2 is sleeved and fixed on the control surface strut 4, the first side plate of the L-shaped fixing plate 1 is fixed to the upper side of the rectangular sleeve 2, and the second side plate is fixed to the wing spars 8. Each U-shaped mounting plate 3 is fixed to both sides of the rectangular sleeve 2 by corresponding flanges. Each servo motor 5 is correspondingly mounted on each U-shaped mounting plate 3 through mounting holes 3.1. Furthermore, the unused end of the control surface strut 4 passes through the skin and is movably connected to the control surface 9.

[0029] In practical implementation, since the mounting bracket uses the rectangular sleeve 2 as the mounting medium, the bracket as a whole is simultaneously and securely connected to the wing spars 8 and the control surface struts 4, providing more connection points to ensure the installation strength of the bracket, prevent structural fatigue caused by long-term use, and improve flight safety. Simultaneously, the U-shaped mounting plates 3 on both sides of the rectangular sleeve 2 form two mounting positions, which not only reduces the number of inspection points for maintenance personnel and increases the efficiency of aircraft maintenance, but also reduces the number of structural parts and lightens the overall weight of the aircraft.

[0030] In one specific implementation, to facilitate installation and maintenance by aircraft personnel, the rectangular sleeve 2 is configured as an assembly structure. Specifically, the rectangular sleeve 2 includes an upper U-shaped plate 2.1, a lower U-shaped plate 2.2, a left side plate 2.3, and a right side plate 2.4 that cooperate with each other. The left side plate 2.3 is fixed to the left end face of the upper U-shaped plate 2.1 and the lower U-shaped plate 2.2, and the right side plate 2.4 is fixed to the right end face of the upper U-shaped plate 2.1 and the lower U-shaped plate 2.2. The rudder surface support rod 8 is fixed to the lower U-shaped plate 2.2. Therefore, if it is necessary to disassemble or install the mounting bracket, only the corresponding upper U-shaped plate 2.1, lower U-shaped plate 2.2, left side plate 2.3, and right side plate 2.4 need to be disassembled or reassembled, without removing the rudder surface support rod 8.

[0031] In one specific implementation, also considering the ease of disassembly and installation of the mounting bracket, the rectangular sleeve 2 is detachably fixed to the rudder surface support rod 8, the L-shaped fixing plate 1, and each U-shaped mounting plate 3. Specifically, each side of the rectangular sleeve 2 has a first fixing hole, and the corresponding positions of the rudder surface support rod 8, the L-shaped fixing plate 1, and each U-shaped mounting plate 3 have a second fixing hole. In this case, each fixing component is simultaneously inserted and fixed within its corresponding first and second fixing holes. In this embodiment, the fixing component is specifically a bolt.

[0032] As a preferred embodiment, to further reduce the weight of the mounting bracket and achieve a lighter design for the corresponding UAV, the rectangular sleeve 2, the control surface strut 8, the L-shaped fixing plate 1, and each U-shaped mounting plate 3 are all made of lightweight metal, lightweight alloy, or carbon fiber composite material. Specifically, they can be aluminum alloy, titanium alloy, etc.

[0033] To improve flight safety and extend the service life of the support structure, all surfaces of the rectangular sleeve 2, the control surface strut 8, the L-shaped fixing plate 1, and each U-shaped mounting plate 3 are designed to be smooth to enhance their weather resistance. Additionally, a waterproof coating can be applied to the surfaces of the rectangular sleeve 2, the control surface strut 8, the L-shaped fixing plate 1, and each U-shaped mounting plate 3 to reduce the corrosive effects of rainwater.

[0034] In summary, this embodiment presents a novel mounting bracket by increasing the number of connection points to reduce flight risks and by implementing compatible mounting positions to reduce the number of brackets required for multi-control surface configurations. Furthermore, it incorporates specific solutions to reduce bracket weight, facilitate assembly, and extend service life, thereby ensuring flight safety and achieving the technical objective of optimizing the overall aircraft's lightweight design.

[0035] This embodiment also provides a drone that mounts its servos using the aforementioned mounting bracket. Specifically, in conjunction with... Figure 2 As shown, the actuator of the servo motor 5 is fixedly mounted in the corresponding mounting hole 3.1. One end of the rocker arm 6 is fixedly engaged with the actuator (i.e., one end of the rocker arm 6 is fitted and fixed to the unused end of the actuator), and the other end is rotatably engaged with the connecting rod 7. The unused end of the connecting rod 7 is rotatably engaged with the arc-shaped rudder angle of the rudder surface 9.

[0036] In practice, the servo motor 5 will sequentially drive the rocker arm 6 and the connecting rod 7 to move, thereby causing the control surface 9 to rotate to adjust the flight attitude of the UAV. Because the UAV incorporates the mounting bracket, its safety during flight is enhanced; and in terms of overall design, it is lighter in multi-control surface scenarios.

[0037] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
