Description

Technical Field

[0001] This utility model relates to the field of unmanned aerial vehicle (UAV) technology, and specifically to a quick-release connection structure for UAV payload modules. Background Technology

[0002] Drone technology has developed rapidly in recent years and is widely used in agriculture, logistics, security, surveying and mapping, and other fields. With the diversification of mission scenarios, drones need to frequently replace payload modules (such as cameras, sensors, and cargo compartments) to adapt to different needs. Modular design has become an industry trend, its core being the realization of rapid assembly and disassembly, stable connection, and electrical integration. Existing quick-release technologies are mainly divided into the following categories: Threaded connection type: The payload module is fastened with screws. Although it has high stability, it requires tools, disassembly is time-consuming and prone to thread wear, and multiple people are needed to operate the transmission rod simultaneously; a single person cannot complete the assembly and disassembly independently. Elastic snap-fit ​​type: It uses springs and plugs, but precise alignment of the slots is required during installation, which can easily lead to incomplete engagement and safety hazards. Modular splicing type: It uses a male-female connector for power and signal transmission, but multiple telescopic contacts need precise alignment, which can easily lead to poor contact under tilted conditions and contact misalignment and signal interruption under vibration.

[0003] In summary, existing quick-release technologies generally suffer from problems such as complex structure, cumbersome operation, and poor compatibility, which limit the efficiency of drone operations. Utility Model Content

[0004] This invention provides a quick-release connection structure for a drone payload module to solve the above-mentioned problems.

[0005] The present invention adopts the following technical solution: a quick-release connection structure for a drone payload module, comprising an upper connecting sleeve, a lower connecting sleeve, a locking component, and a spring pin connector;

[0006] The upper connecting sleeve is cylindrical with its axis set vertically; the upper connecting sleeve is fixed to the lower end of the UAV body.

[0007] The lower connecting sleeve is cylindrical, with its axis vertically positioned below the upper connecting sleeve. The lower connecting sleeve is inserted into the lower end of the upper connecting sleeve. A guide structure is provided between the lower and upper connecting sleeves. The guide structure is used to insert the upper connecting sleeve into the upper connecting sleeve at a fixed position. The load module is located below the lower connecting sleeve and is fixedly connected to the lower connecting sleeve. A pan-tilt unit and a camera are mounted on the load module.

[0008] The locking component is used to lock the lower connecting sleeve inside the upper connecting sleeve after the lower connecting sleeve is inserted into the upper connecting sleeve;

[0009] Spring-loaded pin connectors are used to enable quick-release and rapid connection between the wiring of the payload module and the UAV body.

[0010] Furthermore, the guiding structure includes a guide groove and a guide block;

[0011] The guide groove is located on the outer side wall of the lower connecting sleeve; the guide groove extends vertically; the guide block is rectangular and fixed on the inner side wall of the upper connecting sleeve; the guide block and the guide groove slide vertically together.

[0012] Furthermore, multiple guide structures are distributed circumferentially along the upper connecting sleeve.

[0013] Furthermore, the locking assembly includes a locking hole and a threaded ball catch;

[0014] The threaded ball joint includes a sleeve; the sleeve axis is radially embedded and fixed in the groove wall of the guide groove; the sleeve opening faces away from the axis of the lower connecting sleeve; a ball is slidably installed at the end of the sleeve away from the axis of the lower connecting sleeve; a compression spring is connected between the ball and the sleeve; a locking hole is opened at the end of the guide block near the axis of the upper connecting sleeve.

[0015] Furthermore, the sleeve has threads on its outer side; the threaded ball bearing is M5 type. When installing the payload module, simply hold the lower connecting sleeve with the payload module in one hand, align it with the upper connecting sleeve mounted on the UAV body, and gently rotate it circumferentially to quickly align the guide groove with the guide block. Then, gently push upwards until the ball bearing on the lower connecting sleeve enters the locking hole of the upper connecting sleeve, completing the installation and locking of the upper and lower connecting sleeves. This structure is securely fixed and will not produce any gaps or wobbling. When disassembling the payload module, simply pull the lower connecting sleeve downwards with slight force to release the locking force of the threaded ball bearing, thus completing the disassembly of the payload module.

[0016] Furthermore, the spring-loaded pin connector includes a female spring-loaded pin connector socket and a male spring-loaded pin connector socket;

[0017] The spring-loaded pin connector female is fixed on the upper connecting sleeve and electrically connected to the circuit board of the drone body through wires;

[0018] The male spring-loaded pin connector is fixed to the lower connecting sleeve and electrically connected to the load module via wires. When the load module is installed, the contacts of the male spring-loaded pin connector on the lower connecting sleeve will contact the contacts of the female spring-loaded pin connector on the upper connecting sleeve. The other end of the female spring-loaded pin connector is connected to the power supply and electrical signals from the flight control system, enabling quick connection and disconnection of the power supply and electrical signals for the load module. During the connection process, there is no need to worry about interference between the female and male spring-loaded pin connectors because the pins of the male spring-loaded pin connector have an internal spring with a certain range of extension and contraction.

[0019] Furthermore, a gimbal cover is fixed on the lower connecting sleeve; the gimbal cover is fitted onto the outside of the load module.

[0020] The beneficial effects are: the guide structure allows the upper connecting sleeve to be inserted into the upper connecting sleeve in a fixed position; after the lower connecting sleeve is inserted into the upper connecting sleeve, the locking component locks the lower connecting sleeve inside the upper connecting sleeve. During installation, simply push it gently upwards along the guide structure to complete the quick installation.

[0021] Furthermore, this solution utilizes simple guide grooves and guide blocks, along with commonly available threaded ball bearings. When installing the payload module, simply hold the lower connecting sleeve with the payload module in one hand, align it with the upper connecting sleeve mounted on the drone body, and gently rotate it circumferentially to quickly align the guide groove with the guide block. Then, gently push upwards until the ball bearings on the lower connecting sleeve enter the locking hole of the upper connecting sleeve, completing the installation and locking of the upper and lower connecting sleeves. This structure is securely fixed and prevents any gaps or wobbling. When disassembling the payload module, simply pull the lower connecting sleeve downwards with slight force to release the locking force of the threaded ball bearings, thus completing the disassembly of the payload module.

[0022] Furthermore, this solution uses spring-loaded pin connectors to achieve rapid contact of the electrical control components. The spring-loaded pin connector consists of a male spring-loaded pin connector and a female spring-loaded pin connector. The pins on the male spring-loaded pin connector have a certain range of extension and retraction, which can ensure that there is no interference during connection and that the connection is tight and reliable.
