Description

Technical Field

[0001] This utility model relates to the field of drone design, and in particular to a quick assembly and disassembly structure for the fuselage and accessories of a drone. Background Technology

[0002] Unmanned aerial vehicles (UAVs) are unmanned aerial vehicles with advantages such as flexible deployment and ease of operation, and are widely used in fields such as military reconnaissance, aerial photography, and logistics transportation. A UAV typically consists of a fuselage, as well as accessories such as a tail fin and connecting components. The design of the connection between the fuselage and these accessories has always been a crucial part of UAV design.

[0003] Patent CN202222171911.3 discloses a quick-connect and disconnect structure for model aircraft accessories and fuselage. It features snap-fit ​​connectors and snap-fit ​​seats on both the accessories and fuselage, enabling quick assembly and disassembly. However, this structure uses the position of a lever to determine whether the snap-fit ​​connector and seat are engaged. Normally, the lever is held in place by a spring. In actual operation, drones experience complex forces, and the spring is prone to deformation due to external forces, causing the lever's position to change. This reduces the reliability of the connection between the accessory and fuselage, and in severe cases, may even lead to accessory detachment. Utility Model Content

[0004] The purpose of this utility model is to provide a quick assembly and disassembly structure for the fuselage and accessories of a drone, which can solve one or more of the above-mentioned problems.

[0005] According to one aspect of this utility model, a quick-assembly and disassembly structure for the fuselage and accessories of a drone is provided, comprising a fuselage, accessories, connecting shafts, connecting blocks, a base, a slider, and a locking component.

[0006] The coupling is mounted on the machine body, and the accessory is connected to the coupling.

[0007] One end of the connecting block is connected to the accessory.

[0008] The base is connected to the machine body. The base is provided with a sliding groove and a connecting hole communicating with the sliding groove. The slider is slidably disposed in the sliding groove, and the slider is provided with a locking hole.

[0009] The other end of the connecting block can pass through the connecting hole, one end of the slider can extend into the connecting hole and lock the connecting block onto the base, and the locking member can be connected to the locking hole to fix the slider onto the base.

[0010] The beneficial effects of this utility model are as follows: The connecting shaft facilitates the initial fixation of components such as wings or tail fins to the fuselage. By passing the connecting block through the connecting hole and relying on the sliding slider to lock the connecting block onto the base, the components are fully fixed to the fuselage. Furthermore, the locking mechanism allows the slider to be locked in place after sliding, preventing accidental movement due to external forces and thus improving the reliability of the component's fixation. When disassembly is required, the connection between the locking mechanism and the slider can be separated, and then the slider can be moved to release the connecting block, allowing the component to be effectively removed from the fuselage for quick disassembly.

[0011] In some implementations, the accessory is a wing or a tail fin.

[0012] In some embodiments, the lock includes a lock block, a lock seat, and a spring. The lock seat is connected to a base and has a groove. The lock block is disposed on the groove, with one end protruding from the groove and the other end having a lock head. The spring is sleeved on the lock block, with one end abutting against the lock head and the other end abutting against the bottom of the groove. By incorporating a spring, the lock block can be quickly separated from the slider by the spring force when the lock block is released, thus improving the disassembly speed of the lock block.

[0013] In some embodiments, the base has mounting holes, and the lock seat is embedded in the mounting holes and abuts against the sidewalls of the mounting holes. The mounting holes increase the contact area between the lock seat and the base, improving the reliability of the lock seat on the base.

[0014] In some embodiments, the connecting block includes a connecting rod and a connector. One end of the connecting rod is connected to a fitting, and the other end is connected to the connector. The cross-section of the connector is larger than the cross-section of the connecting rod. The connector can pass through a connecting hole. One end of the slider can extend into the connecting hole and abut against the connecting rod, and form a locking hole within the connecting hole. The connector cannot pass through the locking hole.

[0015] In some embodiments, the slider has a recess, and the connecting rod is embedded in the recess. The recess increases the reliability of the connection when the slider and the connecting rod are engaged, and also limits the position of the connecting rod.

[0016] In some embodiments, the accessory is provided with a through hole, into which the coupling passes. The through hole can limit the connection position of the accessory and the coupling, improving the relative positional accuracy of the accessory and the machine body. Attached Figure Description
