Description

Technical Field

[0001] The present invention relates to the field of unmanned aerial vehicles, and in particular to a supporting mechanism for unmanned aerial vehicles. Background Art

[0002] Drones, also known as unmanned aerial vehicles, are aircraft that do not require human pilots. They can be operated by remote control or autonomous flight and are usually equipped with cameras, sensors and other equipment.

[0003] When the drone is in use, a bracket is installed at the bottom of the drone using bolts so that the bottom of the drone is at a certain distance from the ground, thereby preventing the equipment installed at the bottom of the drone from contacting the ground when the drone takes off or lands.

[0004] Existing drone brackets are usually made of iron frames and installed with bolts. In some mountainous areas or remote uneven ground, when using drones for take-off operations, even if the drone takes off on a road with a certain slope, the bracket at the bottom of the drone contacts the ground, which will cause the drone to be in a tilted take-off state. When the drone takes off on a tilted ground, it may face the following major defects:

[0005] Stability issues: The tilted ground will cause the center of gravity of the drone to shift, making it difficult for the drone to maintain balance during takeoff. This imbalance may cause the drone to roll over or deviate from the intended takeoff direction during takeoff.

[0006] Increased control difficulty: On sloping ground, the drone's controller needs to make more complex adjustments to adapt to the unevenness of the ground, which increases the complexity of the control algorithm and may cause inaccurate attitude control of the drone during takeoff;

[0007] Safety risks: Due to the instability of the sloping ground, the drone may be subjected to uneven support force during takeoff, which may cause additional stress on the landing gear or other components of the drone, increasing the risk of damage. Summary of the invention

A through hole matching the connecting shaft 341 is opened on the side of the mounting shell 31. The connecting shaft 341 forms a linkage with the positioning assembly 35. The clamping member 342 is fixedly connected to one end of the connecting shaft 341. The clamping member 342 corresponds to the locking member 331. The clamping member 342 is symmetrically provided with a clamping plate portion 3421. The clamping member 342 is as shown in FIG. Figure 8 As shown, the handle 344 is fixedly connected to the other end of the connecting shaft 341, the restraining block 343 is fixedly connected to the inside of the mounting shell 31, the distance between adjacent clamping plate portions 3421 is greater than the distance between the opposite sides of adjacent inclined chamfered portions 3316, the width of the clamping plate portions 3421 is less than the width of the locking member 331, the distance between the opposite sides of adjacent clamping plate portions 3421 is less than the distance between adjacent restraining blocks 343, and the chamber inside the mounting shell 31 is sufficient to support the rotation of the clamping member 342, so that when the two clamping plate portions 3421 on the clamping member 342 are in a vertically parallel state, as shown in FIG. Figure 4 As shown, the clamping plate 3421 is inserted between the two locking members 331, so that the two locking members 331 can move away from each other and separate from the installation shaft 32, and the installation shaft 32 can be disassembled.

By removing the limiting column 241, the support plate 21 and the support shell 22 can be disassembled. The bottom of the support plate 21 is symmetrically provided with a guide groove 27 matching the guide rod 26. The buffer spring 25 is slidably sleeved on the outside of the guide rod 26. The buffer spring One end of 25 is squeezed and fitted with the support plate 21. When the drone body 1 lands, the buffer spring 25 can give the drone body 1 an elastic buffering force, and when the drone body 1 is located on the ground through the bracket assembly 2, the weight of the drone body 1 can compress the buffer spring 25, so that the limit column 241 is located in the arc hole 245. When the drone body 1 takes off, under the action of the buffer spring 25, the support shell 22 slides relative to the support plate 21, so that the limit column 241 can slide and be engaged in the limit hole 246, thereby preventing the bracket assembly 2 from shaking relative to the drone body 1 when the drone body 1 is flying.
