Description

Technical Field

[0001] This utility model relates to the field of compass error correction equipment, and in particular to a field compass error correction platform for unmanned aerial vehicles (UAVs). Background Technology

[0002] Drones have a need for alignment correction, which involves placing them on a platform and rotating them. Currently, a solution for drone alignment correction is disclosed in patent document CN212172574U, which describes a drone alignment correction device that achieves the correction effect by rotating a correction platform. However, this solution has a significant drawback: it cannot correct alignment errors when the base encounters uneven ground, thus affecting the alignment correction effect. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a UAV field deviation correction platform. The use of diagonal bracing telescopic rods can improve its adaptability to the ground, and the combination of the lower support platform and the upper support platform can improve its support capacity.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a UAV field error correction platform, including a base, a rotating support shaft and a support platform;

[0005] The base is provided with several rollers and diagonal bracing telescopic rods; the upper end of the diagonal bracing telescopic rods is hinged to the base.

[0006] The rotating support shaft is vertically mounted on the base, and the rotating support shaft is rotatably coupled relative to the base. The rotating support shaft is driven to rotate by a motor.

[0007] The upper end of the rotating support shaft is fixed to the support platform, which is used to place the drone.

[0008] During correction, the entire unit is first placed on the ground and moved to a relatively stable surface using rollers. Then, the base is supported by a diagonal extension rod. The length of the diagonal extension rod is adjusted to adjust the height of the base, ensuring it is level. Next, the drone is placed on the support platform, and the motor drives the rotating support shaft to rotate. The rotating support shaft then drives the support platform to rotate, ultimately achieving the correction of the deviation.

[0009] Preferably, the upper surface of the base is provided with a graduated disk centered on the rotating support axis, and the support platform is provided with an indicator arrow corresponding to the graduated disk. This allows for a clear and intuitive understanding of the angle of rotation of the UAV on the support platform.

[0010] Preferably, the diagonal bracing telescopic rod includes a double-ended screw, an upper cylinder, and a lower cylinder. The two ends of the double-ended screw are threaded into the upper and lower cylinders, respectively. The end of the upper cylinder is hinged to the base, and the end of the lower cylinder is provided with a base plate. The length of the diagonal bracing telescopic rod can be changed by rotating the double-ended screw to provide support for uneven ground.

[0011] Preferably, a handle is provided in the middle of the double-ended screw; the handle includes a handle base and a grip, the handle base is fixed to the double-ended screw, and the grip is hinged to the handle base by a pin. When the length needs to be adjusted, the grip is adjusted to be coaxial with the handle base. After the length adjustment is completed, the grip is swung to be parallel with the double-ended screw to achieve folding and better storage.

[0012] Preferably, a bracket is provided below the base, and the periphery of the bracket is connected to the base upward through several connecting rods. The lower end of the rotating support shaft extends downward to the lower part of the base, and the lower end of the rotating support shaft is rotatably engaged with the bracket through a bearing.

[0013] Using a bracket located below the base can lower the overall center of gravity and make it easier to provide support for the rotating support shaft.

[0014] Preferably, the motor is located on the lower side of the base, and the motor is linked to the rotating support shaft via a reduction gear set. Reducing the motor speed allows for better correction of the drone's rotational errors.

[0015] Preferably, the rotating support shaft includes a lower shaft cylinder and an upper shaft cylinder. The lower shaft cylinder is slidably fitted into the inner cavity of the upper shaft cylinder. The side wall of the upper shaft cylinder is provided with an outer pin hole, and the side wall of the lower shaft cylinder is provided with an inner pin hole corresponding to the outer pin hole. A locking pin passes through the outer pin hole and the inner pin hole to lock the relative position of the upper and lower shaft cylinders. The relative position of the lower and upper shaft cylinders can be changed, and then their length can be changed by locking the relative position with the locking pin to adapt to different error correction situations in actual UAVs.

[0016] Preferably, the support platform includes a lower support platform and an upper support platform, which are connected at the middle. The two ends of the lower support platform are connected to the two ends of the upper support platform via support rods. The lower support platform supports the two ends of the upper support platform via the support rods, thereby improving its overall support strength.

[0017] Preferably, the lower support platform and the upper support platform are detachably connected at their middle sections, and both ends of the support rod are detachably connected to the lower support platform and the upper support platform, respectively. The lower support platform includes a central platform and side platforms. Sliding holes are provided on both sides of the central platform, and telescopic arms inserted into the sliding holes are provided on the side platforms. Fastening bolts are provided on the side walls of the sliding holes, with the front ends of the fastening bolts abutting against the telescopic arms. After use, the lower support platform and the upper support platform are disassembled, and the telescopic arms are retracted into the sliding holes, thus improving space utilization.

[0018] Preferably, the upper support platform has upward-facing support frames at both ends, the lower end of the support frames is hinged to the upper support platform, and the middle part of the support frames is connected to the upper support platform via a tie rod, wherein the tie rod is detachably connected to the support frames and the upper support platform.

[0019] The beneficial effects of this utility model are:

[0020] This solution uses a rotating support shaft to drive the support platform to rotate, thereby driving the UAV to rotate and achieving alignment correction. The structure of the base and support platform provides higher support strength, and the rotating support shaft makes it easier to drive the rotation. Furthermore, the use of diagonal bracing telescopic rods can improve its adaptability to the ground, and the combination of the lower and upper support platforms can enhance the support capacity.
