Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle battery compartments, and in particular to a fixed cover for an unmanned aerial vehicle battery compartment. Background Art

[0002] The domestic drone market has been developing for nearly 30 years, gradually expanding from the initial military field to the consumer field. The domestic consumer drone market is booming, and the recognition and demand of ordinary people for drones are gradually increasing. Drones often need to cope with high-speed flight, rotation, flipping and other flight conditions, as well as various severe weather conditions. As a drone powered by electricity and batteries as a power carrier, the battery compartment protective cover is the best barrier for the power carrier, and the battery compartment needs to be fixed with a fixed cover;

[0003] The current fixed cover is usually a cover plate. During use, the fixed cover is usually snapped onto the bottom of the battery compartment. However, in actual use, due to the different sizes of the battery compartment and the battery, the current fixed cover is usually of a fixed size and cannot be adjusted according to the size of the battery compartment and the battery. It can only be used in combination with a matching battery compartment, and has certain usage restrictions. At the same time, the current fixed cover does not have a protective function. Since the fixed cover is usually installed at the bottom of the drone, the drone is susceptible to collisions caused by external factors when it lands during flight. If it is hit, the impact force cannot be effectively released, resulting in damage to the fixed cover and reducing the service life of the fixed cover. Therefore, we provide a fixed cover for a drone battery compartment. Utility Model Content

[0028] Example

[0029] A technical solution adopted by a fixed cover for a battery compartment of an unmanned aerial vehicle is as follows: it includes a base plate 6, a support plate 5 is fixedly connected to the rear end of the base plate 6, a connection box 3 is fixedly connected to the top of the support plate 5, a rotating rod 1 is movably connected to the center of the top of the connection box 3, a rotating disk 2 is fixedly connected to the top of the rotating rod 1, a first gear 13 is fixedly connected to the surface of the rotating disk 2 and located in the inner cavity of the connection box 3, second gears 14 are meshed on both sides of the first gear 13, a threaded rod 15 is fixedly connected to one side of the second gear 14, a threaded sleeve 16 is threadedly connected to the surface of the threaded rod 15, a support rod 4 is fixedly connected to the surface of the threaded sleeve 16, and a fixed cover plate 8 is fixedly connected to one side of the support rod 4.

[0030] Specifically: when the drone battery compartment needs to be fixed, the user holds the rotating disk 2 and rotates the rotating disk 2 clockwise, drives the rotating rod 1 to rotate through the rotating disk 2, drives the first gear 13 to rotate through the rotating rod 1, drives the second gear 14 to rotate through the first gear 13, and drives the threaded rod 15 to rotate through the second gear 14. Since the threads of the threaded rod 15 are opposite, the threaded sleeve 16 is driven to move to the opposite side through the threaded rod 15, drives the support rod 4 to move to one side through the threaded sleeve 16, and drives the fixed cover plate 8 to move to one side through the support rod 4, so that one side of the fixed cover plate 8 is tightly fitted with both sides of the bottom of the battery compartment, and the fixation is completed. Battery compartments and batteries of different sizes can be fixed without usage restrictions, the fixing effect is better, and the practicability is strong.

[0031] Damper 10 is fixedly connected to all around the bottom of the base plate 6, spring 9 is wound on the surface of the damper 10, and a connecting plate 7 is fixedly connected to the bottom of the damper 10. Mounting blocks 12 are fixedly connected to both sides of the bottom of the connection box 3, and the mounting blocks 12 and the support plate 5 are fixedly connected by mounting bolts 11. Bearings 17 are fixedly connected to both sides of the inner cavity of the connection box 3, and one side of the threaded rod 15 is fixedly connected to the inner ring of the bearing 17. Slide grooves 18 are provided on both sides of the bottom of the inner cavity of the connection box 3, and a slider 19 is fixedly connected to the bottom of the threaded sleeve 16, and the bottom of the slider 19 is slidably connected to the inner cavity of the slide groove 18. A box door is movably connected to the back of the connection box 3, and a handle is fixedly connected to the lower end of the box door surface.

[0032] Specifically: when the drone lands during flight, if the bottom is hit by an external factor, the impactor contacts the bottom of the connecting plate 7, and the impact force generated by the collision drives the connecting plate 7 to move upward, and the spring 9 and the damper 10 are squeezed through the connecting plate 7. The impact force is effectively released through the characteristics of the spring 9, and the fixed cover will not be damaged when hit, thereby increasing its service life.

[0033] The working principle of the utility model is as follows: when it is necessary to fix the battery compartment of the drone, the user holds the rotating disk 2 and rotates the rotating disk 2 in a clockwise direction, drives the rotating rod 1 to rotate through the rotating disk 2, drives the first gear 13 to rotate through the rotating rod 1, drives the second gear 14 to rotate through the first gear 13, and drives the threaded rod 15 to rotate through the second gear 14. Since the threads of the threaded rod 15 are opposite, the threaded sleeve 16 is driven to move to the opposite side through the threaded rod 15, drives the support rod 4 to move to one side through the threaded sleeve 16, and drives the fixed cover plate 8 to move to one side through the support rod 4, so that one side of the fixed cover plate 8 is tightly fitted with the two sides of the bottom of the battery compartment, and the fixation is completed. Battery compartments and batteries of different sizes can be fixed without usage restrictions, the fixing effect is better, and the practicality is strong. When the drone lands during flight, when the bottom is hit by external factors, the impactor contacts the bottom of the connecting plate 7, and the impact force generated by the collision drives the connecting plate 7 to move upward, and the connecting plate 7 is connected. The connecting plate 7 squeezes the spring 9 and the damper 10. Through the characteristics of the spring 9, the impact force is effectively released. When the collision occurs, the fixed cover will not be damaged, thereby improving the service life. The user rotates the mounting bolt 11 with the help of an external tool, and transfers the mounting bolt 11 into the inner cavity of the mounting block 12 and the support plate 5 to complete the installation of the connection box 3. The operation steps are simple and no complicated operation steps are required. The function of quick installation is achieved. Through the setting of the bearing 17, the wear of the threaded rod 15 during the rotation is reduced, and the loss during the rotation of the threaded rod 15 is reduced, thereby greatly improving the service life of the threaded rod 15. During the movement of the threaded sleeve 16, the slider 19 is driven by the threaded sleeve 16 to slide in the inner cavity of the slide groove 18, thereby reducing the shaking of the threaded sleeve 16 during the movement, thereby greatly improving the service life of the threaded sleeve 16. The user holds the handle and pulls the handle outward to open the box door. The user wipes the inner cavity of the connection box 3 with the help of an external tool to improve the cleanliness of the inner cavity of the connection box 3.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
