Abstract
Description
Technical Field
[0001] This utility model belongs to the field of unmanned aerial vehicles (UAVs), specifically relating to a hatch opening and closing mechanism for an unmanned aerial vehicle (UAV) pod. Background Technology
[0002] Currently, drone technology is undergoing rapid changes. Due to their flexibility, maneuverability, and ability to perform long-range, high-altitude operations, drones can be applied to various fields. The application of drones, based on remote-controlled flight, can be designed according to specific application scenarios.
[0003] Some transport or delivery equipment needs to be stored inside the drone's cabin before use, so a cabin door opening and closing mechanism needs to be designed for protection.
[0004] Currently available hatch opening and closing mechanisms are typically quite complex, primarily relying on screw drives. Their dustproof performance and lifespan are unsatisfactory, and they also consume a significant amount of energy. For lightweight equipment, there is room for further improvement in this structure. Utility Model Content
[0005] To address the problems and shortcomings of existing technologies, the purpose of this utility model is to provide a hatch opening and closing mechanism for unmanned aerial vehicle (UAV) pods, which has a more reasonable structure, lower energy consumption, and features dustproof and long service life.
[0006] A hatch opening and closing mechanism for an unmanned aerial vehicle (UAV) pod includes a hatch frame, a hatch sliding cover, a drive motor, and a slide rail assembly. The hatch frame has grooves on both sides for placing the drive motor. The slide rail assembly is located on the same side as the drive motor. The hatch sliding cover is connected to the slide rail assembly on both sides. The slide rail assembly can drive the hatch sliding cover to move horizontally on the hatch frame. The drive motor is connected to the slide rail assembly and can drive the slide rail assembly to move horizontally on the hatch frame.
[0007] Furthermore, the drive slide rail assembly is provided in two sets. Each set of drive slide rail assembly includes a translational fixed slide rail and two translational movable slide rails. The translational fixed slide rail is fixedly installed on the side of the hatch frame, and the two translational movable slide rails are respectively set on the inner and outer sides of the translational fixed slide rail.
[0008] Furthermore, racks are provided on the inner sides of both translational slide rails, and gears are provided on the shaft of the drive motor. The racks and gears cooperate with each other, and the drive motor drives the two translational slide rails to move in opposite directions.
[0009] Furthermore, the translational fixed slide rail has a motor mounting hole in the middle, and the upper end of the drive motor is fixedly installed at the motor mounting hole.
[0010] Furthermore, the fixed sliding rail includes an upper rail, a middle rail, and a lower rail. The lower rail is fixedly connected to the hatch frame, and the two sliding sliding rails slide in cooperation with the upper and middle rails.
[0011] Furthermore, several rolling plungers are provided on the sides of both the upper and middle rails, and the rolling plungers are in rolling cooperation with the translational sliding rail.
[0012] The advantages of this utility model are:
[0013] 1. Through the coordinated assembly of the door frame, drive motor and sliding fixed rail, the opening and closing mechanism is assembled in a very compact manner, without taking up extra space in the drone cabin, thus achieving the effect of lightweight design.
[0014] 2. At the joint between the fixed slide rail and the sliding slide rail, several rolling plungers are placed to reduce friction and buffer errors. They also suspend the surface from surface friction to line friction, thus reducing the sliding blockage caused by dust accumulation. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] A hatch opening and closing mechanism for an unmanned aerial vehicle (UAV) pod includes a hatch frame, a hatch sliding cover, a drive motor, and a slide rail assembly. The hatch frame has grooves on both sides for housing the drive motor. The slide rail assembly is located on the same side as the drive motor. The hatch sliding cover is connected to the slide rail assembly on both sides. The slide rail assembly can drive the hatch sliding cover to translate on the hatch frame. The drive motor is connected to the slide rail assembly and can drive the slide rail assembly to translate on the hatch frame. There are two sets of drive rail assemblies. Each set includes a fixed translational slide rail and two movable translational slide rails. The fixed translational slide rail is fixedly installed on the side of the hatch frame. The two movable translational slide rails are respectively located on the inner and outer sides of the fixed translational slide rail. Each movable translational slide rail has a rack on its inner side. The drive motor shaft has a gear. The rack and gear mesh, and the drive motor drives the two movable translational slide rails to translate towards each other. The fixed translational slide rail has a motor mounting hole in its center, and the upper end of the drive motor is fixedly installed at the motor mounting hole. The fixed sliding rail includes an upper rail, a middle rail, and a lower rail. The lower rail is fixedly connected to the hatch frame, and the two sliding sliding rails slide in conjunction with the upper and middle rails. Several rolling plungers are provided on the sides of both the upper and middle rails, and these rolling plungers roll in conjunction with the sliding sliding rails.
[0024] The practical application method is as follows:
[0025] The sliding of the hatch cover is primarily achieved through the cooperation of a slide rail assembly and a drive motor. The fixed sliding rails in the slide rail assembly are fixedly installed on both sides of the hatch frame, while the drive motor is mounted at the bottom of the fixed sliding rails. Its shaft (equipped with gears) is located between the upper and middle rails. A rack mounted on the sliding sliding rail also moves between the upper and middle rails. Therefore, when the drive motor gears rotate, it drives the hatch covers on both sides to move towards each other, thus enabling the opening and closing of the unmanned aerial vehicle (UAV) hatch.
[0026] like Figure 5 As shown, the upper surface of the upper rail and the lower surface of the middle rail are both provided with long grooves, and the translational sliding rail moves on the translational fixed sliding rail by means of the long grooves.
[0027] like Figure 2 As shown, the drive motor is located in a groove in the door frame, which allows space for the drone nest.
[0028] The main components of the mechanism are two sliding rails with a static and dynamic relationship. The sliding rail has a rack fixed inside it with screws for driving. A motor connected to a gear acts as the driving component, driving the mechanism composed of the sliding rail and the rack. At the mating point between the fixed and sliding sliding rails, there is a bottom hole for a rolling plunger. This reduces friction and buffers errors. Furthermore, by changing from surface friction to line friction, it provides a suspension effect to prevent dust blockage, reducing sliding obstruction caused by dust accumulation.
[0029] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
