[0002] The drone battery is a core component that provides power for the drone's flight and the operation of its various parts. Its performance directly affects the drone's flight time, flight stability, and overall work efficiency. The most common type of drone battery is the lithium polymer battery, which features high energy density, light weight, and high malleability, meeting the drone's requirements for lightweight design and long flight time. In addition, lithium-ion batteries are also used in some drone products. To improve the drone's operational efficiency, a quick-change device is needed.

[0003] The magnetic drone battery quick-change device is a high-efficiency battery replacement device designed based on the principle of magnetic adsorption. In previous technologies, the battery was usually placed in a work box and fixed by simply relying on the cooperation between the work box and the magnetic parts of the drone. This method still has the risk of insufficient connection strength and the battery is prone to shaking. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a magnetic drone battery quick replacement device, which aims to improve the problem of battery shaking caused by simply relying on the cooperation between the working box and the magnetic parts of the drone to fix the battery.

[0014] This utility model has the following beneficial effects:

[0015] 1.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-3 An embodiment of this utility model provides a magnetic fast-change device for drone batteries, including a working box 1, a battery body 2 inside the working box 1, a storage box 3 fixedly connected to the outer wall of the working box 1, a magnet 4 inside the storage box 3, a worm gear 5 rotatably connected inside the working box 1, a worm wheel 6 meshing with the tooth end of the worm gear 5, a connecting column 7 fixedly connected inside the worm wheel 6, an eccentric wheel 8 fixedly connected to the top of the connecting column 7, a clamping block 9 slidably connected to the outer wall of the eccentric wheel 8, a telescopic rod 10 fixedly connected to the left outer wall of the clamping block 9, the outer wall of the telescopic rod 10 fixedly connected to the inside of the working box 1, a tension spring 11 fixedly connected to the inner wall of the working box 1, the outer wall of the tension spring 11 fixedly connected to the outer wall of the clamping block 9, a cover plate 12 on the lower surface of the storage box 3, and a limit component on the upper surface of the cover plate 12.

[0025] Specifically, by utilizing the interface of the battery body 2 and the interface of the drone battery compartment, when the interface of the battery body 2 is inserted into the interface of the drone, the magnetic components at the interface of the drone battery, including the magnet 4, are used to maintain the stability of the top of the battery body 2 after installation. The clamping block 9 is used to limit the block set on the lower side of the battery body 2, thereby maintaining the stability of the bottom of the battery body 2 after installation. The worm gear 5 has a handle on its front side, which facilitates the rotation of the worm gear 5. Through the cooperation between the worm gear 5 and the worm wheel 6, the rotation of the connecting column 7 and the eccentric wheel 8 is self-locked, thereby self-locking the movement of the clamping block 9. The telescopic rod 10 is used to support the movement of the clamping block 9.

[0026] Reference Figure 3The limiting component includes a limiting pad 13, the lower surface of the limiting pad 13 is fixedly connected to the upper surface of the cover plate 12, the upper surface of the limiting pad 13 is disposed on the lower surface of the magnet 4, and the outer wall of the limiting pad 13 is slidably connected to the inner wall of the storage box 3.

[0027] Specifically, the magnet 4 is matched with the inside of the storage box 3 and placed inside the storage box 3. The cover plate 12 and the limiting pad 13 are used to make the limiting pad 13 hold the magnet 4, thereby reducing the shaking of the magnet 4.

[0028] Reference Figure 2 The bottom end of the connecting column 7 is rotatably connected to the inside of the working box 1, and the outer wall of the clamping block 9 is set on the outer wall of the battery body 2.

[0029] Specifically, the rotation of the connecting column 7 inside the working box 1 achieves the effect of support and limitation. Clamping blocks 9 are provided on both sides of the battery body 2, and the movement of the clamping blocks 9 limits or releases the battery body 2.

[0030] Reference Figure 4 A concave frame 14 is fixedly connected to the outer wall of the cover plate 12, and a triangular block 15 is provided on the outer wall of the concave frame 14; a pull rod 16 is fixedly connected to the front outer wall of the triangular block 15, and a telescopic rod 18 is fixedly connected to the rear outer wall of the triangular block 15; the outer wall of the telescopic rod 18 is fixedly connected to the inside of the storage box 3, and a tension spring 19 is provided on the outer wall of the telescopic rod 18; one end of the tension spring 19 is fixedly connected to the outer wall of the triangular block 15, and the other end of the tension spring 19 is fixedly connected to the outer wall of the storage box 3; a protective frame 17 is fixedly connected to the outer wall of the storage box 3, and the outer wall of the protective frame 17 is provided on the outer wall of the triangular block 15;

[0031] Specifically, concave frames 14 are provided on both sides of the cover plate 12 to improve the stability of the cover plate 12 installation. Without external force driving the triangular block 15, the tension of the second tension spring 19 makes the triangular block 15 fit tightly with the protective frame 17. The second telescopic rod 18 is used to improve the stability of the triangular block 15 when it moves, and also to support the triangular block 15. The protective frame 17 is used to protect the second telescopic rod 18 and the second tension spring 19, and also to hold the triangular block 15 in place so that the final position of the triangular block 15 is consistent. The triangular block 15 slides in and out inside the concave frame 14 to limit or release the concave frame 14.

[0032] Working principle: When using this device, the magnet 4 inside the storage box 3 matches the magnetic component at the drone's battery compartment to remove the used battery. Hold the work box 1 and move the battery body 2 toward the drone's battery interface. Through the cooperation between the storage box 3 and the drone's magnetic component, the battery body 2 is kept stable after installation, thereby enabling quick replacement of the drone's battery.

[0033] When different sized batteries are needed, the worm 5 is rotated, which drives the worm wheel 6 to rotate, thereby driving the connecting column 7 and the eccentric wheel 8 to rotate. As the eccentric wheel 8 rotates, it no longer holds the clamping block 9. Under the tension of the tension spring 11, the clamping block 9 moves to the outside of the working box 1, compressing the telescopic rod 10. After the movement of the clamping block 9, it no longer limits the battery body 2, making it easy to take the battery body 2 out of the working box 1, so that different battery bodies 2 can be replaced inside the working box 1.

[0034] When different magnets 4 are needed, by holding the storage box 3 and pulling the lever 16, the triangular block 15 moves forward, causing the telescopic rod 18 to stretch under the support of the storage box 3. At the same time, the tension spring 19 is also stretched. After the triangular block 15 slides out of the concave frame 14, it is no longer limited, allowing the cover plate 12 and the concave frame 14 to be removed smoothly. The limiting pad 13 slides out of the inner wall of the storage box 3, no longer limiting the magnet 4, making it easy to take out the magnet 4 for maintenance or replacement. During use, this device not only facilitates the replacement of different battery bodies 2, but also enables the limiting or release of the magnet 4, reducing the shaking or collision of the magnet 4 inside the storage box 3.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
