Description

Technical Field

[0001] This utility model relates to the field of drone storage compartment technology, specifically a sealed opening and closing structure for a drone storage compartment. Background Technology

[0002] In the field of drones, storage compartments are used to store various items such as express parcels, surveying equipment, and emergency supplies. Their sealed opening and closing structure is crucial to ensuring the safety of the items and the overall performance of the drone. Currently, most common drone storage compartment opening and closing structures use simple hinge connections combined with springs or manual control to open and close the compartment doors.

[0003] However, during actual drone flight, this conventional structure is prone to door shaking and jamming due to vibrations and airflow impacts. This not only affects the normal opening and closing of the door but also easily leads to a decrease in sealing performance, allowing rainwater and dust from the outside to enter the storage compartment and damage the items inside. At the same time, after long-term use, components such as hinges are prone to wear, further reducing the reliability and service life of the structure, making it difficult to meet the high requirements of drones for the sealing and opening of the storage compartment in complex flight environments. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a sealed opening and closing structure for a drone storage compartment to solve the problems mentioned in the background. This utility model has a novel structure. By setting up a gear and rack transmission, a worm gear drive, and an L-shaped guide groove structure, the sealing door first moves horizontally and then rises vertically to close. The movement trajectory is precise and stable, which greatly reduces the impact of drone flight vibration on the opening and closing process. At the same time, the sealing door and the sealing gasket on the inner wall of the storage compartment are tightly fitted, which effectively improves the sealing performance, prevents external dust and rainwater from entering the storage compartment, ensures the safety of the items inside the compartment, and improves the pain point of insufficient reliability of conventional structures.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sealed opening and closing structure for a drone storage compartment, comprising a drone body, a storage cavity on the upper side of the drone body, an installation cover plate installed on the upper side of the inner wall of the storage cavity, an installation frame on the lower side of the installation cover plate, a rack plate fixedly connected to the lower side of the installation frame, two support plates symmetrically fixedly connected to the lower side of the installation cover plate, a rotating shaft rotatably fitted on the two support plates, a gear fixedly connected to the rotating shaft and meshing with the rack plate, a driving mechanism on the lower side of the installation cover plate, a storage and retrieval slot on the upper side of the installation cover plate, and a sealing door between the installation frame and the installation cover plate that cooperates with the storage and retrieval slot.

[0006] Furthermore, a sealing gasket is fixedly connected to the inner wall of the access slot, and the sealing gasket cooperates with one side of the sealing door.

[0007] Furthermore, the drive mechanism includes a drive motor mounted on the underside of the mounting cover plate, the output end of the drive motor is fixedly connected to a worm gear, the end of the rotating shaft near the worm gear is fixedly connected to a worm wheel, the worm gear meshes with the worm wheel, and one end of the worm gear is rotatably engaged on one side of the support plate.

[0008] Furthermore, multiple connecting rods are provided between the sealing door and the mounting frame, with both ends of the connecting rods rotatably engaging with the sealing door and the mounting frame respectively, and the connecting rods being located at the four corners of the sealing door.

[0009] Furthermore, a guide plate is fixedly connected to the lower side of the mounting cover, and an L-shaped guide groove is provided on one side of the guide plate. The vertical section of the L-shaped guide groove corresponds to the position of the access slot.

[0010] Furthermore, one of the multiple connecting rods near the outer side of the guide plate has a roller rotatably engaged on its lower side, and the roller is slidably engaged on the inner wall of the L-shaped guide groove.

[0011] Furthermore, two guide rails are installed on the lower side of the mounting cover, and multiple guide wheels are installed on both sides of the mounting bracket, with the guide wheels cooperating with the inner wall of the guide rails.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model, by setting up a gear and rack transmission, worm gear drive and L-shaped guide groove guiding structure, enables the sealing door to move horizontally first and then rise vertically to close. The movement trajectory is precise and stable, which greatly reduces the impact of drone flight vibration on the opening and closing process. At the same time, the sealing door and the inner wall sealing gasket of the storage slot are tightly fitted, which effectively improves the sealing performance, prevents external dust and rainwater from entering the storage compartment, ensures the safety of the items in the compartment, and improves the pain point of insufficient reliability of conventional structures.

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Please refer to Figures 1 to 6This utility model provides a technical solution: a sealed opening and closing structure for a drone storage compartment, including a drone body 1, a storage cavity 2 on the upper side of the drone body 1, a mounting cover 3 installed on the upper side of the inner wall of the storage cavity 2, a mounting frame 4 on the lower side of the mounting cover 3, a rack plate 5 fixedly connected to the lower side of the mounting frame 4, two support plates 6 symmetrically fixedly connected to the lower side of the mounting cover 3, a rotating shaft 7 rotatably engaged on the two support plates 6, a gear 8 fixedly connected to the rotating shaft 7 and meshing with the rack plate 5, a drive mechanism 9 on the lower side of the mounting cover 3, a storage slot 10 on the upper side of the mounting cover 3, and a sealing door 11 between the mounting frame 4 and the mounting cover 3 that cooperates with the storage slot 10. A sealing gasket 12 is fixedly connected to the inner wall of the storage slot 10, and the sealing gasket 12 cooperates with one side of the sealing door 11. The drive mechanism 9 includes a drive motor 91 mounted on the underside of the mounting cover plate 3. A worm gear 92 is fixedly connected to the output end of the drive motor 91. A worm wheel 93 is fixedly connected to the end of the rotating shaft 7 near the worm gear 92. The worm gear 92 meshes with the worm wheel 93, and one end of the worm gear 92 rotatably engages with one side of the support plate 6. Initially, the sealing door 11 is open. When it is necessary to close the sealing door 11, the drive motor 91 of the drive mechanism 9 is activated. The drive motor 91 drives the worm gear 92 to rotate. The worm gear 92 meshes with the worm wheel 93, causing the rotating shaft 7 and gear 8 to rotate synchronously. The gear 8 meshes with the rack plate 5, pushing the mounting frame 4 to move horizontally along the guide rail 17. This process utilizes the self-locking property of the worm gear 92 and worm wheel 93 and the precise meshing of the gear 8 and rack plate 5 to ensure the smooth movement of the mounting frame 4, providing stable power for the subsequent movement of the sealing door 11 and preventing power transmission issues. Unstable delivery causes the sealing door 11 to shift. When the mounting bracket 4 moves horizontally, the connecting rods 13 at its four corners synchronously drive the sealing door 11 to move. At the same time, the rollers 16 on the lower side of the connecting rods 13 near the outer side of the guide plate 14 slide along the horizontal section of the L-shaped guide groove 15 to the vertical section. Under the guidance of the L-shaped guide groove 15, the rollers 16 drive the connecting rods 13 to change the direction of movement, so that the sealing door 11 changes from horizontal movement to vertical rise. This guidance and transmission work together to ensure that the movement trajectory of the sealing door 11 is accurate, avoid jamming or shifting, and ensure that it can be accurately aligned with the access slot 10.

[0024] In this embodiment, multiple connecting rods 13 are provided between the sealing door 11 and the mounting frame 4. The two ends of each connecting rod 13 are rotatably engaged with the sealing door 11 and the mounting frame 4, respectively. The connecting rods 13 are located at the four corners of the sealing door 11. A guide plate 14 is fixedly connected to the lower side of the mounting cover plate 3. An L-shaped guide groove 15 is formed on one side of the guide plate 14, and the vertical section of the L-shaped guide groove 15 corresponds to the position of the access slot 10. A roller 16 is rotatably engaged on the lower side of one of the multiple connecting rods 13 closest to the outer side of the guide plate 14. The roller 16 slides against the inner wall of the L-shaped guide groove 15. Two guide rails 17 are installed on the lower side of the mounting cover plate 3. Multiple guide wheels 18 are installed on both sides of the mounting frame 4, and the guide wheels 18 engage with the inner walls of the guide rails 17. When the sealing door 11 rises vertically to the storage slot 10, one side of it fits tightly against the sealing gasket 12 on the inner wall of the storage slot 10. The elastic deformation of the sealing gasket 12 fills the gap, thus sealing the storage cavity 2. When the sealing door 11 needs to be opened, the drive motor 91 rotates in the opposite direction, the mounting bracket 4 moves horizontally in the opposite direction, and the roller 16 slides back to the horizontal section along the vertical section of the L-shaped guide groove 15, causing the sealing door 11 to first descend vertically and then move horizontally to the open state. The sealing gasket 12 ensures the sealing when closed, and the reverse movement ensures that the sealing door 11 opens smoothly without affecting the storage and retrieval of items.

[0025] When using the device, the initial sealing door 11 is open. When closing, the drive motor 91 drives the worm gear 92 and worm wheel 93 to rotate, causing the gear 8 on the rotating shaft 7 to mesh with the rack plate 5, pushing the mounting frame 4 to move horizontally along the guide rail 17. The mounting frame 4 drives the sealing door 11 to move through the connecting rod 13. The roller 16 slides horizontally along the L-shaped guide groove 15 and then enters the vertical section, guiding the sealing door 11 from horizontal movement to vertical rise, and finally it fits with the sealing gasket 12 of the storage slot 10 to achieve a seal. When opening, the drive motor 91 rotates in the opposite direction, the mounting frame 4 moves in the opposite direction, and the roller 16 slides vertically down along the L-shaped guide groove 15 and then slides horizontally, driving the sealing door 11 to descend first and then move horizontally back to the open state. The entire process is achieved through the cooperation of mechanical structures to achieve precise opening and closing and reliable sealing.
