Description

Technical Field

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

[0002] As drone applications become increasingly widespread, the requirements for drone manufacturing are also becoming more stringent. Among these requirements, the IMU (Integrated Measurement Unit), a core sensor in the drone flight control system, consists of accelerometers, gyroscopes, and magnetometers, and can measure various data in real time. By fusing this sensor data, the IMU provides precise attitude and motion feedback, helping the flight control system achieve stable flight control and navigation. Therefore, the IMU plays a crucial role in drone takeoff, flight, and landing, ensuring that the drone maintains balance, flies stably, and responds to external interference.

[0003] Before a drone leaves the factory, its flight control system needs to be leveled. The traditional leveling method involves placing the drone's flight control system on a table or a special instrument for leveling and testing. This method has problems such as low accuracy, complex operation, and high cost. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a simple flight control leveling device to solve the problems of complex operation and high cost of UAV flight control leveling in the prior art.

[0005] To achieve the above and other related objectives, the technical solution of this utility model is as follows:

[0006] A simple flight control leveling device includes:

[0007] A support base for fixing the base to the ground or platform;

[0008] A fine-tuning slide is mounted on the support base. The fine-tuning slide includes several sets of adjustment mechanisms and a slide upper plate. The adjustment mechanisms are used to adjust the slide upper plate to a horizontal position.

[0009] The test box is placed on the upper plate of the slide. The test box has a receiving cavity for holding the UAV flight controller. A notch is provided on one side of the test box for the cable of the UAV flight controller to pass through.

[0010] Optionally, the adjustment mechanism is in two sets, which are used to adjust the horizontal position of the slide plate from two horizontal directions.

[0011] Optionally, the adjustment mechanism includes a micrometer, a stop block, and a guide rail assembly. The guide rail assembly includes an upper guide rail and a lower guide rail, which are slidably connected by rollers. The mating part of the upper and lower guide rails is arc-shaped. The micrometer is fixed to the lower guide rail, and the stop block is fixed on the upper guide rail. The front end of the micrometer is aligned with the stop block. When the front end of the micrometer extends, it pushes the stop block forward, causing the upper guide rail to move along the lower guide rail.

[0012] Optionally, a spring-back mechanism is provided between the upper guide rail and the lower guide rail, the spring-back mechanism being used to spring back when the front end of the micrometer moves backward.

[0013] Optionally, the rebound structure is a spring, which is arranged between the upper guide rail and the lower guide rail.

[0014] Optionally, the two sets of adjustment mechanisms are vertically overlapped and fixedly connected, and the adjustment directions of the two sets of adjustment mechanisms are perpendicular to each other.

[0015] Optionally, the support base includes a base plate, support rods, and a slide lower plate. There are several support rods, and several support rods are fixed between the fixed support base plate and the slide lower plate.

[0016] Optionally, the base support plate has four legs, which are located at the four corners of the base support plate, and the base support plate has a hollow hole in the middle.

[0017] Optionally, there are four support rods, the upper end of which is fixed to the lower plate of the slide by bolts, and the lower end of which is fixedly connected to the base support plate.

[0018] Optionally, the test box is fixedly connected to the UAV flight controller by bolts.

[0019] As described above, this utility model has the following beneficial effects: The device is fixedly supported by a support base, and the upper plate of the slide is leveled using a fine-tuning slide table to ensure it is in a horizontal state; the leveling process is convenient and quick. When leveling and calibrating the UAV flight controller, the UAV flight controller is fixed inside the test box, and then the test box is placed horizontally on the upper plate of the slide table, allowing for horizontal calibration of several surfaces of the UAV flight controller. Compared with existing technologies, this device offers simple and low-cost leveling operation for UAV flight controllers, enabling rapid calibration of UAV sub-controllers and thus improving the production efficiency of UAV flight controllers.

Detailed Implementation

[0024] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0025] It should be understood that this invention can be embodied in various forms and should not be construed as being limited to the embodiments set forth herein. Rather, providing these embodiments will make the disclosure thorough and complete, and will fully convey the scope of this invention to those skilled in the art. In the drawings, the same reference numerals denote the same components throughout.

[0026] In this utility model, a simple flight control leveling device is described, in conjunction with [see reference 1] Figures 1 to 2 The device includes:

[0027] Support base 10, which is used to fix the base to the ground or platform;

[0028] A fine-tuning slide 20 is disposed on the support base 10. The fine-tuning slide 20 includes several sets of adjustment mechanisms and a slide upper plate 25. The several adjustment mechanisms are used to adjust the slide upper plate 25 to a horizontal position.

[0029] Test box 30 is placed on the slide plate 25. Test box 30 has a receiving cavity for placing UAV flight controller 40. A notch 31 is provided on one side of test box 30 for the cable of UAV flight controller 40 to pass through.

[0030] In actual implementation, the support base 10 serves as a fixed platform for horizontally and stably placing the fine-tuning slide 20. It can be a box-type structure or a frame-type structure, and can be movable or fixed in the desired position. It can be an integral structure or a detachable structure. The fine-tuning slide 20 is used to adjust the horizontal position of the slide plate 25. Adjusting the horizontal position of the slide plate 25 is particularly important and requires high precision. The fine-tuning slide 20 can finely adjust the vertical position of various points on the slide plate 25, thus ensuring that the slide plate 25 is horizontal. The test box 30 is suitable for fixing the UAV flight controller 40 and testing the horizontality of its various surfaces. Therefore, the test box 30 needs to accommodate the UAV flight controller 40 and facilitate the connection of the UAV flight controller 40 to external structures; therefore, it is provided with a notch 31.

[0031] In use, the device is fixedly supported by the support base 10, and then the slide plate 25 is leveled by the fine-tuning slide 20 to ensure that the slide plate 25 is in a horizontal state. The leveling process is convenient and quick. When leveling and calibrating the UAV flight controller 40, the UAV flight controller 40 is fixed in the test box 30, and then the test box 30 is placed horizontally on the slide plate 25 to calibrate the level of several surfaces of the UAV flight controller 40.

[0032] In some embodiments, the adjustment mechanism comprises two sets, which are used to adjust the horizontal position of the slide plate 25 from two horizontal directions. For example, Figure 2 As shown, the two sets of adjustment mechanisms can adjust the horizontal position of the slide plate 25 from two different directions, thereby finely adjusting the horizontal state of the slide plate 25 to ensure its usage requirements.

[0033] In some embodiments, the adjustment mechanism includes a micrometer 23, a stop block 21, and a guide rail assembly. The guide rail assembly includes an upper guide rail 21 and a lower guide rail 22, which are slidably connected by rollers. The mating part of the upper guide rail 21 and the lower guide rail 22 is arc-shaped. The micrometer 23 is fixed to the lower guide rail 22, and the stop block 24 is fixed on the upper guide rail 21. The front end of the micrometer 23 is aligned with the stop block 24. When the front end of the micrometer 23 extends, it pushes the stop block 24 forward, causing the upper guide rail 21 to move along the lower guide rail 22.

[0034] Specifically, such as Figure 2As shown, one side of the upper guide rail 21 and the lower guide rail 22 is a cooperating arc surface 26. Viewed from the side, one side of the upper guide rail 21 and the lower guide rail 22 is an arc. When the upper guide rail 21 slides along the lower guide rail 22, the upper guide rail 21 will move along the arc, which allows the slide plate 25 to swing at a small angle, thereby adjusting the horizontal position of the slide plate 25. In order to accurately control the sliding of the upper guide rail 21, a stop block 24 is fixed on the upper guide rail 21, and a micrometer 23 is fixed on the lower guide rail 22 by a bracket 231. The movement direction of the micrometer 23 head is consistent with the sliding direction of the upper guide rail 21. By rotating the micrometer 23 to extend its head, the stop block 24 is pushed to move slightly, thereby allowing the upper guide rail 21 to slide a small distance, and the angle of the slide plate 25 can be adjusted at a small angle.

[0035] In some embodiments, a spring-back mechanism is provided between the upper guide rail 21 and the lower guide rail 22. The spring-back mechanism is used to spring back when the front end of the micrometer 23 moves backward. In order to make the stop 24 move in the opposite direction as the head of the micrometer 23 retracts, a spring-back device is provided inside the upper guide rail 21 and the lower guide rail 22. The head of the micrometer 23 extends out and abuts against the stop 24, so that the spring-back device has a spring force. When the head of the micrometer 23 retracts, the stop 24 moves back with the head of the micrometer 23 under the action of the spring force.

[0036] In some embodiments, the rebound structure is a spring, which is arranged between the upper guide rail 21 and the lower guide rail 22. For example, to make the structure of this device more reasonable and easier to manufacture, the spring structure is placed inside the adjustment mechanism, and the spring is selected as the main structural component of the rebound device. One end of the spring is fixed to the stop block 24, and the other end is fixed to any point on the lower guide rail 22.

[0037] In some embodiments, the two sets of adjustment mechanisms are vertically overlapped and fixedly connected, and the adjustment directions of the two sets of adjustment mechanisms are perpendicular to each other. For example, Figure 2 As shown, two adjustment mechanisms are arranged in an overlapping manner, so that the adjustment directions of the adjustment mechanisms do not interfere with each other when they are perpendicular to each other, so as to facilitate the adjustment of the horizontal position of the slide plate 25.

[0038] In some embodiments, the support base 10 includes a base plate 11, support rods 12, and a lower slide plate 13. There are multiple support rods 12, which are fixed between the base plate 11 and the lower slide plate 13. For example, Figure 1 As shown, the support base 10 is set by the base support plate 11, the support rod 12 and the slide lower plate 13, which has a simple structure, saves materials and has low cost.

[0039] In some embodiments, the base support plate 11 has four legs 111 located at the four corners of the base support plate 11, and the base support plate 11 has a perforated hole 112 in the center. For example, Figure 1 As shown, the four legs 111 facilitate the stable placement of the support base 10 in various scenarios, and the perforated holes 112 also facilitate the placement of this device.

[0040] In some embodiments, there are four support rods 12. The upper ends of the support rods 12 are fixed to the lower slide plate 13 by bolts, and the lower ends of the support rods 12 are fixedly connected to the base support plate 11. For example, Figure 2 As shown, the four support rods 12 can keep the lower slide plate 13 stable and greatly simplify the structure of the support base 10.

[0041] In some embodiments, the test box 30 is bolted to the drone flight controller 40. For example, Figure 1 As shown, this design enables the UAV flight controller 40 to be quickly fixed to the test box 30 without loosening during the test, and also facilitates the UAV flight controller 40 to be quickly detached from the test box 30 after the test is completed.

[0042] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
