[0002] The battery of an agricultural drone is the core energy component that powers the drone and is a key piece of equipment that ensures the drone can complete field operations such as pesticide spraying and crop monitoring.

[0003] The battery storage structure of some existing agricultural drones is relatively simple. When transport vehicles carry agricultural drones and their batteries into mountainous areas for operation, the poor road conditions can easily cause the drone batteries to be bumped and damaged, resulting in problems such as shell deformation and internal micro-short circuits, which affect the stability of use. Furthermore, in extremely cold outdoor weather, it is inconvenient to protect the agricultural drones at a suitable temperature for charging. Utility Model Content

[0004] The main purpose of this utility model is to provide a protective storage device for drone batteries, which aims to solve the problem that the battery storage structure of some existing agricultural drones is relatively simple. When transporting agricultural drones and their batteries into mountainous areas, the poor road conditions can easily cause the drone batteries to be bumped, resulting in problems such as shell deformation and internal micro-short circuits, affecting the stability of use. Furthermore, it is inconvenient to protect the agricultural drones at a suitable temperature for charging in extremely cold outdoor weather.

[0005] To achieve the above objectives, this utility model proposes a protective storage device for drone batteries, comprising a storage box, a box cover, a lithium battery body for agricultural drones, and a charging port. The storage box is equipped with a protective mechanism inside, has an opening inside, is equipped with an electric heating wire inside, and has a controller on the front side of the storage box.

[0006] The protective mechanism includes a tray, a groove, a buffer protective sleeve, and a notch. The groove is formed inside the buffer protective sleeve, and the surface of the tray contacts the inner wall of the groove. The notch is formed inside the buffer protective sleeve, and the surface of the lithium battery body of the agricultural drone contacts the inner wall of the buffer protective sleeve.

[0007] Preferably, the inner wall of the box lid is fixedly connected with a cushioning pad, and the number of the cushioning pads is two.

[0008] Preferably, nylon straps are fixedly connected to the front and rear sides of the top of the pallet, and the buffer sleeve and the buffer pad are both made of high-density polyurethane foam.

[0009] Preferably, a connecting frame is fixedly connected to the left side of the storage box, and the connecting frame is connected to the opening.

[0010] Preferably, silicone sheets are fixedly connected to the top and bottom of the inner wall of the opening, with the top and bottom silicone sheets in contact on opposite sides.

[0011] Preferably, a sealing block is provided on the left side of the connecting frame, and a sealing cover is fixedly connected to the left side of the sealing block. The surface of the sealing block is in contact with the inner wall of the connecting frame. A pull ring is fixedly connected to the left side of the sealing cover. Limit buttons are fixedly connected to the front and rear sides of the left side of the sealing cover. The right side of the limit button passes through the sealing cover and is threaded into the inside of the connecting frame.

[0012] Preferably, hinges are provided on both sides of the top rear side of the storage box, and the connection between the box lid and the storage box is rotatably connected by the hinges.

[0013] Preferably, the storage box is provided with buckle locks on both sides of the front side, and the lid of the storage box is made of polycarbonate.

[0014] In this invention, the lithium battery of the agricultural drone is placed inside a buffer protective sleeve, with the tray positioned within a groove. This prevents direct friction between the battery and the tray, thus avoiding wear. The lid is then closed, and the lid and storage box are secured with latches. Both the buffer protective sleeve and the buffer pad are made of high-density polyurethane foam, which offers excellent elasticity and cushioning properties. This foam comprehensively wraps the lithium battery from multiple directions, effectively absorbing external vibrations and impacts during transport or movement, providing comprehensive cushioning protection and preventing damage to the lithium battery. If the battery is damaged due to impact, when charging the lithium battery of the agricultural drone in extremely cold outdoor environments, the heating wire can be activated via the controller. The heating wire generates the necessary heat to heat the lithium battery inside the storage box. Simultaneously, the high-density polyurethane foam has excellent insulation properties, reducing heat loss and maintaining a suitable temperature environment for the lithium battery, preventing charging from being affected by low temperatures. Then, remove the limit button and pull the ring to detach the sealing cover and sealing block from the connecting frame. At this point, the opening is open to the outside. Pass the external charging plug between the two silicone sheets. The silicone sheets are elastic and can tightly seal the connection. The fitting of the plug provides a seal, preventing heat dissipation. Afterward, connect the external charging plug to the charging port to begin charging. In low-temperature environments, charging without proper heating and insulation of the battery will slow down lithium-ion migration, significantly reducing charging efficiency. More seriously, lithium ions cannot quickly embed into the negative electrode graphite, instead accumulating on the negative electrode surface to form needle-like lithium dendrites. These dendrites can easily pierce the separator inside the agricultural drone's lithium battery, causing direct contact between the positive and negative electrodes, leading to a short circuit and potentially causing bulging, fire, or even explosion. Controlling the heating wire via a controller effectively prevents these damages. When using agricultural drones... To access the lithium battery for the agricultural drone, simply open the latch, lift the lid, and use the nylon strap to pull the tray out of the storage box. The nylon strap is foldable and will not affect the normal closing of the lid. This solves the problem of the simple battery storage structure of some existing agricultural drones. When transporting the agricultural drone and its battery into mountainous areas, the poor road conditions can easily cause the battery to be bumped, resulting in shell deformation, internal micro-short circuits, and other problems, affecting the stability of use. Furthermore, it is inconvenient to protect the agricultural drone at a suitable temperature for charging in extremely cold outdoor weather. Attached Figure Description

[0027] This utility model provides a protective storage device for drone batteries, which aims to solve the problem that the existing battery storage structure of some agricultural drones is relatively simple. When transporting agricultural drones and their batteries into mountainous areas, the poor road conditions can easily cause the drone batteries to be bumped, resulting in problems such as shell deformation and internal micro-short circuits, affecting the stability of use. Furthermore, in extremely cold outdoor weather, it is inconvenient to protect the agricultural drones at a suitable temperature for charging.

[0028] like Figure 1-5 As shown, the present invention provides a protective storage device for drone batteries, including a storage box 1, a box cover 5, a lithium battery body 3 for agricultural drones and a charging port 17. The storage box 1 is provided with a protective mechanism 7, an opening 13, an electric heating wire 16, and a controller 18 on the front side of the storage box 1.

[0029] The protective mechanism 7 includes a tray 701, a groove 702, a buffer protective sleeve 703, and a notch 704. The groove 702 is formed inside the buffer protective sleeve 703, and the surface of the tray 701 contacts the inner wall of the groove 702. The notch 704 is formed inside the buffer protective sleeve 703, and the surface of the plant protection drone lithium battery body 3 contacts the inner wall of the buffer protective sleeve 703.

[0030] In this utility model's technical solution, by placing the lithium battery body 3 of the agricultural drone inside the buffer protective sleeve 703, with the tray 701 located inside the groove 702, direct friction between the lithium battery body 3 and the tray 701 can be avoided, preventing wear. Then, the lid 5 is closed, and the lid 5 and storage box 1 are secured using the latch lock 2. Since both the buffer protective sleeve 703 and the buffer pad 4 are made of high-density polyurethane foam, this material has good elasticity and cushioning performance, fully wrapping the lithium battery body 3 of the agricultural drone from multiple directions (top, bottom, left, and right). During transportation or movement, it can effectively absorb external vibrations and impacts, providing comprehensive cushioning protection and preventing damage. The lithium battery body 3 of the agricultural drone was damaged by an impact. When charging the lithium battery body 3 of the agricultural drone in an extremely cold outdoor environment, the electric heating wire 16 can be activated through the controller 18. The electric heating wire 16 generates the required heat to heat the lithium battery body 3 of the agricultural drone inside the storage box 1. At the same time, the high-density polyurethane foam cotton itself has good heat insulation properties, which can reduce heat loss and keep the lithium battery body 3 of the agricultural drone in a suitable temperature environment, avoiding the impact of low temperature on charging. Then, remove the limit button 15, and pull the pull ring 14 to remove the sealing cover 8 and sealing block 10 from the connecting frame 12. At this time, the opening 13 is open to the outside. Insert the external charging plug between the two silicone sheets 11. The silicone sheet 11, being elastic, fits tightly against the plug, providing a seal and preventing heat loss. Then, the external charging plug is connected to the charging port 17 for charging. In low-temperature environments, charging without proper heating and insulation of the battery can slow down lithium-ion migration, significantly reducing charging efficiency. More seriously, lithium ions cannot quickly embed into the negative electrode graphite, accumulating on the negative electrode surface to form needle-like lithium dendrites. These dendrites can easily pierce the separator inside the lithium battery body 3 of the agricultural drone, causing direct contact between the positive and negative electrodes, leading to a short circuit and potentially causing bulging, fire, or even explosion. Controlling the heating wire 16 via the controller 18 effectively prevents these damages. To use the lithium battery body 3 of the agricultural drone, open the latch lock 2, lift the lid 5, and use the nylon strap 9 to pull the tray 701 out of the storage box 1 to take out the lithium battery body 3 of the agricultural drone for use. The nylon strap 9 can be folded for storage without affecting the normal closing of the lid 5. This solves the problem that the battery storage structure of some existing agricultural drones is relatively simple. When transporting agricultural drones and their batteries into mountainous areas, the poor road conditions can easily cause the agricultural drone batteries to be bumped, resulting in problems such as shell deformation and internal micro-short circuits, which affect the stability of use. In addition, it is inconvenient to protect the agricultural drone at a suitable temperature for charging in extremely cold outdoor weather.

[0031] Please refer to the following: Figure 1The inner wall of the box cover 5 is fixedly connected with two buffer pads 4. In this embodiment, the two buffer pads 4 on the inner wall of the box cover 5 can form a top buffer protection zone for the lithium battery body 3 of the agricultural drone from the top, enhancing the longitudinal protection of the lithium battery body 3 of the agricultural drone and reducing the direct collision between the lithium battery body 3 of the agricultural drone and the box cover 5 during the closing of the box cover 5 and transportation.

[0032] For further information, please continue to refer to [link / reference]. Figure 1 and Figure 2 Nylon pull straps 9 are fixedly connected to the front and rear sides of the top of the tray 701. The buffer protective sleeve 703 and the buffer pad 4 are both made of high-density polyurethane foam. In this embodiment, the nylon pull straps 9 facilitate pulling the tray 701, thereby facilitating quick and easy loading and unloading of batteries and improving operational convenience. The buffer protective sleeve 703 and the buffer pad 4, made of high-density polyurethane foam, have both excellent cushioning and heat insulation properties, preventing bumps and maintaining a stable internal temperature of the storage box 1.

[0033] Please continue to refer to this. Figure 3 A connecting frame 12 is fixedly connected to the left side of the storage box 1, and the connecting frame 12 is connected to the opening 13. In this embodiment, the connection between the connecting frame 12 and the opening 13 provides a channel for the access of the external charging plug and also provides convenience for the connection of the sealing cover 8.

[0034] Please refer to Figure 3 Silicone sheets 11 are fixedly connected to the top and bottom of the inner wall of the opening 13, with the top and bottom silicone sheets 11 in contact with each other on opposite sides. In this embodiment, the silicone sheets 11 in contact at the opening 13 can prevent heat dissipation inside the storage box 1 without affecting the insertion of the plug.

[0035] Additionally, please refer to Figure 3 A sealing block 10 is provided on the left side of the connecting frame 12, and a sealing cover 8 is fixedly connected to the left side of the sealing block 10. The surface of the sealing block 10 contacts the inner wall of the connecting frame 12. A pull ring 14 is fixedly connected to the left side of the sealing cover 8. Limit buttons 15 are fixedly connected to the front and rear sides of the left side of the sealing cover 8. The right side of the limit button 15 passes through the sealing cover 8 and is threadedly connected to the inside of the connecting frame 12. In this embodiment, the sealing block 10 contacts the inner wall of the connecting frame 12, forming a tight seal on the connecting frame 12. When charging is not required, the opening 13 is sealed. The limit button 15 enables quick installation and removal of the sealing cover 8, and the pull ring 14 facilitates the removal and placement of the sealing cover 8, balancing sealing performance and ease of operation.

[0036] Please refer to Figure 1Hinges 6 are provided on both sides of the top rear side of the storage box 1, and the lid 5 is rotatably connected to the storage box 1 via the hinges 6. In this embodiment, the hinges 6 connect the lid 5 and the storage box 1, allowing for flexible rotation and ensuring smooth opening and closing of the lid 5.

[0037] Additionally, please refer to Figure 1 The storage box 1 has latches 2 on both sides of its front side, and both the storage box 1 and the lid 5 are made of polycarbonate. In this embodiment, the latches 2 can securely lock the lid 5 to the storage box 1, preventing the lid 5 from opening accidentally during transportation. The polycarbonate body and lid 5 are strong, wear-resistant, and lightweight, improving the durability and portability of the device.

[0038] It should be noted that when charging the plant protection drone battery in a normal temperature environment, the plant protection drone battery needs to be removed from the buffer protective cover 703 to avoid the plant protection drone battery from generating heat during charging and not being able to dissipate in time, which may pose a safety hazard. Furthermore, the electric heating wire 16 and the controller 18 are both existing and mature technologies that are already published and are powered by an external power source. The latch lock 2 is also an existing and mature technology that is already published. The basic mechanism of these technologies will not be elaborated here.

[0039] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
