[0005] The utility model aims to solve the shortcomings in the prior art and proposes a lightweight battery structure for an unmanned aerial vehicle.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A lightweight battery structure for a drone, comprising a lower shell, a fixing mechanism, a battery mechanism and a drone body;

[0008] The lower shell is movably connected to the upper shell, the lower shell is provided with a placement plate, the placement plate is provided with a placement groove, the placement groove is provided with a drone body, the lower shell is provided with a battery mechanism, the battery mechanism is adapted to the drone body, the upper shell is provided with a fixing mechanism, and the fixing mechanism is connected to the drone body;

[0009] The fixing mechanism includes a threaded rod 1, a movable plate 1, an extrusion plate, a threaded rod 2, a movable plate 2 and a baffle. The upper shell is rotatably connected with the threaded rod 1. Through the coordinated design of the lower shell, the upper shell, the fixing mechanism, the clamping block 1 and the clamping block 2, not only can the effect of limiting and fixing the drone bodies of different sizes be achieved, but also the effect of replacing the two extrusion plates and the baffle according to actual conditions can be conveniently achieved, thereby improving convenience and scope of application.

[0010] Specifically, the threaded rod 1 is threadedly connected to two moving plates 1, and the two moving plates 1 are both clamped with a clamping block 1, and the two clamping blocks 1 are fixedly installed with extrusion plates, and the two extrusion plates are both in contact with the drone body. The two extrusion plates are provided with rubber pads and are in contact with the drone body. When the threaded rod 2 is rotated, the threaded rod 2 and the two moving plates 2 are threadedly transmitted and the two moving plates 2 are made to slide on the threaded rod 1. Since the threads at both ends of the threaded rod 2 are opposite, the moving plates 2 move in opposite directions. At the same time, the two moving plates 2 respectively drive the two baffles to move synchronously through the transmission of the two clamping blocks 2, and the two baffles are made to contact with the two sides of the drone body, thereby achieving the effect of fixing and limiting drone bodies of different sizes.

[0011] Specifically, a threaded rod 2 is rotatably connected to the upper shell, and the two movable plates 1 are slidably connected to the threaded rod 2. Two movable plates 2 are threadedly connected to the threaded rod 2, and the two movable plates 2 are slidably connected to the threaded rod 1. When the threaded rod 2 is rotated, the threaded rod 2 and the two movable plates 2 are threadedly transmitted and the two movable plates 2 slide on the threaded rod 1. Since the threads at both ends of the threaded rod 2 are opposite, the moving directions of the two movable plates 2 are opposite. At the same time, the two movable plates 2 respectively drive the two baffles to move synchronously through the transmission of the two blocking blocks 2, and the two baffles are in contact with the two sides of the drone body, thereby achieving the effect of fixing and limiting drone bodies of different sizes.

[0012] Specifically, the two movable plates are each clamped with a clamping block, and the two clamping blocks are each fixedly mounted with a baffle, and the two baffles correspond to the drone body and are used to fix and limit the drone body to improve stability.

[0013] Specifically, one end of the threaded rod 1 and the threaded rod 2 both pass through the upper shell and are fixedly connected with a rotating plate to facilitate the rotation of the threaded rod 1 and the threaded rod 2. The threads at both ends of the threaded rod 1 and the threaded rod 2 are opposite.

[0014] Specifically, the two card blocks 2 have the same structure as the two card blocks 1 and both have a certain elasticity. The two card blocks 1 and the two card blocks 2 are each provided with a deformation groove. By squeezing one end of the deformation grooves of the two card blocks 1 and the two card blocks respectively, one end of the two card blocks 1 and the two card blocks are deformed, and one end of the two card blocks 1 and the two card blocks are disengaged from the corresponding card grooves on the two movable plates 1 and the movable plates 2. Then, the two card blocks 1 and the two card blocks 2 are pulled out of the corresponding card grooves respectively, thereby achieving the effect of disassembling the two extrusion plates and the baffle plate, and then achieving the effect of replacing the two suitable extrusion plates and the baffle plate according to actual conditions, thereby improving the scope of application.

[0015] Specifically, an observation window is provided on the upper shell, and the observation window corresponds to the drone body. The observation window can facilitate observation of the internal situation.

[0016] Specifically, the lower shell is provided with a switch and a USB charging port, and both are connected to the battery mechanism. The upper shell is provided with a display and is connected to the battery mechanism. The lower shell and the upper shell are provided with two identical buckles to facilitate the connection between the lower shell and the upper shell. The battery mechanism includes a lithium battery pack, an inverter, a rectifier, a wireless charging module, a lithium battery protection board, a coulomb meter, a central processing unit and a micro transformer. The wireless charging module and the lithium battery pack are electrically connected to each other through the inverter. When the drone is stored inside the tank, the wireless charging module is sensed by the drone battery and can call the internal battery power of the lithium battery pack through the central processing unit, thereby automatically performing wireless charging for the drone located inside the drone card slot. The specific structure and working principle of the battery mechanism can refer to the document with application number: 202320150925.9. This is the prior art and will not be elaborated on.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Reference Figure 1-4 , a lightweight battery structure for a drone, comprising a lower shell 1, a fixing mechanism, a battery mechanism 4 and a drone body 5;

[0028] The fixing mechanism includes a threaded rod 1 6, a movable plate 1 7, an extrusion plate 9, a threaded rod 2 10, a movable plate 2 11 and a baffle 13. The threaded rod 1 6 is rotatably connected to the upper shell 2. Through the coordinated design of the lower shell 1, the upper shell 2, the fixing mechanism, the clamping block 1 8 and the clamping block 2 12, not only can the drone bodies 5 of different sizes be limited and fixed, but also the two extrusion plates 9 and the baffle 13 can be easily replaced according to actual conditions, thereby improving convenience and scope of application.

[0029] In this embodiment, two moving plates 17 are threadedly connected to the threaded rod 16, and a clamping block 18 is clamped on the two moving plates 7. Extrusion plates 9 are fixedly installed on the two clamping blocks 8. The two extrusion plates 9 are in contact with the drone body 5. The two extrusion plates 9 are provided with rubber pads and are in contact with the drone body 5. When the threaded rod 2 10 is rotated, the threaded rod 2 10 and the two moving plates 2 11 are threadedly transmitted and the two moving plates 2 11 are made to slide on the threaded rod 1 6. Since the threads at both ends of the threaded rod 2 10 are opposite, the moving directions of the two moving plates 2 11 are opposite. At the same time, the two moving plates 2 11 respectively drive the two baffles 13 to move synchronously through the transmission of the two clamping blocks 2 12, and the two baffles 13 are made to contact with the two sides of the drone body 5, thereby achieving the effect of fixing and limiting drone bodies 5 of different sizes.

[0030] In this embodiment, a threaded rod 2 10 is rotatably connected to the upper shell 2, and two movable plates 7 are slidably connected to the threaded rod 2 10. Two movable plates 2 11 are threadedly connected to the threaded rod 2 10, and the two movable plates 2 11 are slidably connected to the threaded rod 1 6. When the threaded rod 2 10 is rotated, the threaded rod 2 10 and the two movable plates 2 11 are threadedly transmitted and the two movable plates 2 11 slide on the threaded rod 1 6. Since the threads at both ends of the threaded rod 2 10 are opposite, the two movable plates 2 11 move in opposite directions. At the same time, the two movable plates 2 11 respectively drive the two baffles 13 to move synchronously through the transmission of the two clamping blocks 2 12, and the two baffles 13 are in contact with the two sides of the drone body 5, thereby achieving the effect of fixing and limiting the drone bodies 5 of different sizes.

[0031] In this embodiment, the two movable plates 11 are both connected with a card block 12, and the two card blocks 12 are both fixedly installed with a baffle 13. The two baffles 13 correspond to the drone body 5 and are used to fix and limit the drone body 5 to improve stability.

[0032] In this embodiment, one end of the threaded rod 1 6 and the threaded rod 2 10 both pass through the upper shell 2 and are fixedly connected to a rotating plate 14 to facilitate the rotation of the threaded rod 1 6 and the threaded rod 2 10. The threads at both ends of the threaded rod 1 6 and the threaded rod 2 10 are opposite.

[0033] In this embodiment, the two card blocks 12 have the same structure as the two card blocks 1 8 and both have a certain elasticity. Deformation grooves are provided on the two card blocks 1 8 and the two card blocks 12. By squeezing one end of the deformation grooves of the two card blocks 1 8 and the two card blocks 12 respectively, one end of the two card blocks 1 8 and the two card blocks 12 are deformed, and one end of the two card blocks 1 8 and the two card blocks 12 are separated from the corresponding card grooves on the two movable plates 1 7 and the movable plate 2 11. Then, the two card blocks 1 8 and the two card blocks 12 are pulled out of the corresponding card grooves respectively, so as to achieve the effect of disassembling the two extrusion plates 9 and the baffle plate 13, and then achieve the effect of replacing the two extrusion plates 9 and the baffle plate 13 according to actual conditions, thereby improving the scope of application.

[0034] In this embodiment, an observation window 15 is provided on the upper shell 2 , and the observation window 15 corresponds to the drone body 5 . The observation window 15 can be used to conveniently observe the internal conditions.

[0035] In this embodiment, the lower shell 1 is provided with a switch and a USB charging port, and both are connected to the battery mechanism 4. The upper shell 2 is provided with a display and is connected to the battery mechanism. The lower shell 1 and the upper shell 2 are provided with two identical buckles to facilitate the connection between the lower shell 1 and the upper shell 2. The battery mechanism 4 includes a lithium battery pack, an inverter, a rectifier, a wireless charging module, a lithium battery protection board, a coulomb meter, a central processing unit and a micro transformer. The wireless charging module and the lithium battery pack are electrically connected to each other through the inverter. When the drone is stored inside the tank, the wireless charging module is sensed by the drone battery and can call the internal battery power of the lithium battery pack through the central processing unit, thereby automatically performing wireless charging for the drone located inside the drone card slot. The specific structure and working principle of the battery mechanism 4 can refer to the document with application number: 202320150925.9. This is the prior art and will not be elaborated on.

[0036] Working principle: When in use, first place the drone body 5 in the placement groove on the placement plate 3, then rotate the upper shell 2 and close the upper shell 2 and the lower shell 1. In this process, the upper shell 2 is driven by the threaded rod 1 6, the threaded rod 2 10, and the two movable plates 1 7 so that the two extrusion plates 9 are in contact with the drone body 5, thereby achieving the effect of limiting the drone body 5; then, by rotating the threaded rod 2 10, the threaded rod 2 10 and the two movable plates 2 11 are threadedly driven. Since the threads at both ends of the threaded rod 2 10 are opposite, the two movable plates 2 11 move in opposite directions, and then the two movable plates 2 11 respectively drive the two baffles 13 to a certain extent toward the drone body 5 and are in contact with the drone body 5, thereby achieving the effect of further limiting the drone body 5, and then achieving the effect of preventing the drone body 5 from moving;

[0037] The threaded rod 16 and the threaded rod 2 10 are rotated respectively by two rotating plates 14. When the threaded rod 16 is rotated, the threaded rod 16 and the two movable plates 17 are threadedly driven and the two movable plates 17 are both slid on the threaded rod 2 10. Since the threads at both ends of the threaded rod 16 are opposite, the two movable plates 17 move in opposite directions, thereby achieving the effect of adjusting the distance between the two movable plates 17. At the same time, the two movable plates 17 drive the two extrusion plates 9 to move synchronously through the two clamping blocks 18, and at the same time, through the function of the placement plate 3, the effect of conveniently clamping and fixing the drone bodies 5 of different sizes is achieved.

[0038] When the threaded rod 10 is rotated, the threaded rod 10 and the two moving plates 11 are threadedly driven and the two moving plates 11 slide on the threaded rod 1 6. Since the threads at both ends of the threaded rod 10 are opposite, the two moving plates 11 move in opposite directions. At the same time, the two moving plates 11 drive the two baffles 13 to move synchronously through the transmission of the two clamping blocks 12, and the two baffles 13 are in contact with the two sides of the drone body 5, so as to achieve the effect of fixing and limiting the drone bodies 5 of different sizes.

[0039] By squeezing one end of the deformation grooves of the two card blocks 1 8 and the two card blocks 12 respectively, the one ends of the two card blocks 1 8 and the two card blocks 12 are deformed, and the one ends of the two card blocks 1 8 and the two card blocks 12 are separated from the corresponding card grooves on the two movable plates 1 7 and the movable plate 2 11, and then the two card blocks 1 8 and the two card blocks 12 are pulled out of the corresponding card grooves respectively, so as to achieve the effect of disassembling the two extrusion plates 9 and the baffle plate 13, and then achieve the effect of replacing the two suitable extrusion plates 9 and the baffle plate 13 according to actual conditions, thereby improving the scope of application.

[0040] The wireless charging module and the lithium battery pack are electrically connected to each other through an inverter. When the drone is stored inside the tank, the wireless charging module is sensed by the drone battery and can call up the internal battery power of the lithium battery pack through the central processor, thereby automatically performing wireless charging for the drone located inside the drone card slot.

[0041] The observation window 15 can be used to facilitate observation of the internal conditions.

[0042] The technical progress achieved by the utility model compared with the prior art is that through the cooperation of various components, not only can the effect of limiting and fixing the drone bodies 5 of different sizes be achieved, but also the effect of replacing the two extrusion plates 9 and the baffle 13 according to actual conditions can be conveniently achieved, thereby improving convenience and scope of application, and the structure is simple and easy to operate, and the practicality is higher.
