Description

Technical Field

[0001] This utility model belongs to the field of drone technology, specifically relating to a combined drone battery charging box. Background Technology

[0002] In today's era of rapid technological advancement, drone technology has achieved rapid progress thanks to its unique advantages. From a technical perspective, key performance indicators such as flight stability, endurance, and control precision of drones have been continuously optimized. In terms of functional expansion, advanced technologies such as high-definition cameras, thermal imaging, and LiDAR are constantly being integrated, greatly enriching their application scenarios. This series of advancements has resulted in a diverse and complex user base for drones, encompassing both professionals and general consumers. The application areas of drones are becoming increasingly widespread, deeply penetrating multiple industries. As various industries become more reliant on drones, the number of drones in use is steadily increasing over time, and the related supporting software and hardware are also undergoing rapid iteration.

[0003] Within the hardware and software ecosystem of drones, the charging issue of drone batteries is becoming increasingly prominent, posing a bottleneck to the industry's further development. Currently, limited by the power consumption and endurance technology of drones, a single drone often needs to be equipped with multiple batteries to meet the continuous power demands during field operations. Drone battery charging scenarios are mainly divided into outdoor and indoor types, both of which present pressing challenges. For example, in indoor charging scenarios, many industries have a need for centralized charging of large numbers of drone batteries. However, existing charging equipment, due to considerations such as cost control, technical implementation difficulty, and equipment compatibility, can only charge a limited number of batteries simultaneously per device. To achieve batch charging of more drone batteries, multiple charging devices must be used concurrently. This approach brings several drawbacks: on the one hand, it places high demands on the number of power supply interfaces, requiring a large number of power sockets on-site; on the other hand, the numerous power lines intertwined make wiring extremely cumbersome, increasing installation costs and time, and posing safety hazards such as the risk of short circuits caused by tangled wires. Furthermore, the lack of real-time data synchronization between charging devices makes it difficult for managers to centrally manage the charging status of all drone batteries. This hinders timely access to crucial information such as charging progress and battery health, reducing overall operational efficiency. In outdoor charging scenarios, drones frequently switch between different operational environments, making timely battery replenishment essential. However, equipment suitable for mass charging operations is typically bulky and heavy, making it difficult for staff to carry around during fieldwork.

[0004] This shows that existing drone charging equipment is significantly inadequate and cannot simultaneously meet the charging needs of drone batteries both outdoors and indoors. Utility Model Content

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0039] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0040] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0041] In the description of the embodiments of this utility model, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use, they are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the utility model. Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0042] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted.

[0044] The technical terms involved in this utility model are explained below:

[0045] USB stands for Universal Serial Bus, a standardized interface technology designed to simplify connections and data transfer between electronic devices.

[0046] TYPE-C stands for USB Type-C, which is a physical form of USB interface and was released by the USB-IF Association in 2014.

[0047] The present invention will now be described in further detail with reference to the accompanying drawings:

[0048] like Figure 1 As shown, this embodiment provides a combined drone battery charging box, including a box body 1. The box body 1 serves as the outer shell of the entire charging box, protecting the internal components and providing a mounting base.

[0049] The housing 1 contains a first charging device 2 and a second charging device 3.

[0050] Combination Figure 2 and Figure 3As shown, the first charging device 2 is fixedly connected to the housing 1. The first charging device 2 includes a first AC power input port 4. The first AC power input port 4 adopts a triangular interface, which provides power to the entire charging box through an external 220V AC power source such as AC mains. It also includes a first DC input port 6, which can be used to connect to DC power sources such as power banks, increasing the flexibility of power access. It is also equipped with at least one first DC output port 7. In this embodiment, the first charging device 2 is also provided with a first DC output port 7 for power transmission connection and data synchronization with the second charging device 3. Multiple first battery charging ports 9 are provided. In this embodiment, nine are provided, arranged in an array, which can charge multiple drone batteries simultaneously. Furthermore, the first charging device 2 also integrates a first display screen 5, which can display the operating status of the first charging device 2 in real time, including the current temperature of the device, the current mode, and detailed battery information (such as battery SN code, cycle count, production date), etc., for user monitoring. The first data transmission interface 8 uses a USB interface or a TYPE-C interface for data interaction with external devices, such as updating the charging program.

[0051] Of course, both the first charging device 2 and the second charging device 3 of this combined drone battery include a charging device body, which includes a main control unit, a buck-boost circuit, circuit protection devices, a battery status monitoring device, a data management and storage unit, a heat dissipation structure, etc.; its specific functions are as follows:

[0052] The main control unit is responsible for charging logic control, such as the National Technology N32G435 series chip, for protocol processing, voltage regulation and communication interaction; the main control unit also integrates a battery management system to monitor battery voltage, current and temperature in real time to prevent overcharging or over-discharging.

[0053] The buck-boost circuit uses a controller (such as TIBQ25700A) and a switching transistor (such as AOSAON7544MOSFET) to match the wide voltage input (such as 5-20V) with the battery charging requirements, supports multi-channel independent charging, and can handle multiple batteries at the same time.

[0054] Circuit protection devices include overvoltage / overcurrent protection devices, such as TVS diodes (e.g., Yangjie SMAJ24CA) and MOSFETs (e.g., Weizhao VS3510AE), used to prevent abnormal current from damaging the equipment.

[0055] Circuit protection devices also include temperature protection devices, which monitor the temperature of critical components through thermistors and combine them with heat sinks or thermal conductive gels for forced heat dissipation.

[0056] The battery status monitoring device includes a voltage sensor and a temperature sensor, which can collect battery data in real time and trigger protection mechanisms (such as suspending charging when overheating).

[0057] The data management and storage unit is used to record charging logs (such as charging times, duration, and abnormal events), and supports data export or cloud synchronization.

[0058] A fan can be used for heat dissipation to ensure stable operation in high-temperature environments.

[0059] The aforementioned components in the charging device body are not the technical means to be improved by this utility model. Therefore, in this embodiment, the aforementioned components will not be described in detail.

[0060] For example Figure 2 and Figure 3 As shown, the second charging device 3 is housed within the casing 17, which is wrapped in foam. This foam serves two purposes: cushioning and protection, and also allows for easy detachable connection through a locking mechanism between the foam and the cavity of the casing 1. This detachable connection allows users to flexibly increase or decrease the number of second charging devices 3 according to their needs; it also facilitates the assembly and disassembly of the second charging devices 3, enabling separate use of the second charging devices 3 and their combination with the first charging device 2. The second charging device 3 includes a second AC power input port 10, which can also be connected to a 220V AC power source, and a second DC input port 12. The second charging device 3 also includes multiple second battery charging ports 14; in this embodiment, eight are provided. When used in combination with the first charging device 2, the first DC output port 7 and the second DC input port 12 of both devices are connected via a double-ended DC interface cable. This double-ended DC interface cable has a built-in communication pin, preferably a 4-pin communication pin, which enables data communication between the two devices, coordinating parameters such as charging power, and thus achieving real-time data synchronization. The second charging device 3 is also equipped with a second display screen 11, which is used to display the charging status of its connected battery separately. The second data transmission interface 13 adopts a TYPE-C interface or a USB interface to meet the connection needs of different external devices.

[0061] In addition, the second charging device 3 is equipped with a toggle button 15, which is electrically connected to the second AC power input port 10 and the second DC input port 12 respectively. Users can easily switch the power input mode using the toggle button 15. Multiple fan vents 16 are distributed on the surface of the second charging device 3, which, together with several ventilation holes opened on the side wall of the housing 1, form a heat dissipation channel to ensure that heat is dissipated in a timely manner during charging, thus ensuring charging safety and device lifespan.

[0062] This embodiment provides a combined drone battery charging box, the specific working principle of which is as follows:

[0063] When in an indoor charging operation scenario, the first charging device 2 and the second charging device 3 are used together. The first DC output port 7 of the first charging device 2 and the second DC input port 12 of the second charging device 3 are connected through a double-ended DC interface cable to ensure reliable current transmission and realize data synchronization between charging devices, thus meeting the needs of indoor batch centralized charging.

[0064] When in an outdoor charging operation scenario, the second charging device 3 is removed from the housing 1 via the box 17, making it separate into an independent charging unit; of course, in this embodiment, when the second charging device 3 is separated from the housing 1, the first charging device 2 is also an independent charging unit, and the cavity that accommodates the second charging device 3 can also serve as a cavity for the drone, making it convenient for the drone to be carried together with the first charging device 2 as a whole.

[0065] Since the second charging device 3 has a second AC power input port 10, it can be connected to a 220V AC power source independently, enabling the power input of the second charging device 3 to charge the drone battery inserted in the second battery charging port 14. Since the second charging device 3 is separated from the housing 1, the weight and volume of the overall combined drone battery charging box are greatly reduced, making it easy to carry and meeting the needs of frequent switching between different work scenarios.

[0066] Compared with existing drone battery charging equipment, the combined drone battery charging box provided by this utility model has the following advantages:

[0067] In indoor charging scenarios, this charging box features multiple battery charging ports. By connecting the first DC output port and the second DC input port of two charging devices, it can meet the centralized charging needs of large numbers of drone batteries. Unlike existing systems, it eliminates the need to use multiple charging devices simultaneously, reducing the requirement for a large number of power interfaces and avoiding the hassle of equipping numerous power outlets on-site. It also reduces the cumbersome wiring problems caused by tangled power cords, lowering installation costs and time, and eliminating the safety hazard of short circuits caused by tangled wires. Furthermore, the connection between the first DC output port and the second DC input port facilitates data transmission across the entire charging box, enabling centralized management. Managers can monitor the charging progress and health status of all drone batteries in real time, significantly improving overall operational efficiency. In outdoor charging scenarios, the second charging device is relatively independent and can be used in combination with the first charging device. Its design is more portable, solving the problem that traditional mass-produced charging devices are bulky and heavy and difficult to carry. When workers are working outdoors, they can carry it more easily and replenish the power of the drone battery in a timely manner, ensuring the power needs of the drone when frequently switching between different work scenarios. This effectively solves the current problems of drone battery charging in indoor and outdoor scenarios and promotes the further development of the drone industry.

[0068] The above embodiments are merely one of the implementation methods to achieve the technical solution of this utility model. The scope of protection claimed by this utility model is not limited to this embodiment, but also includes any variations, substitutions and other implementation methods that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this utility model.
