Description

Technical Field

[0001] The present application relates to the technical field of unmanned aerial vehicles, and in particular to a battery module for a cross-medium unmanned aerial vehicle, a battery module and a unmanned aerial vehicle. Background Art

[0002] Due to the complexity of drone equipment configuration, it consumes significant battery energy, resulting in frequent replacement and charging of battery packs. Especially in the operation scenarios of cross-medium drones, their rapid conversion and shuttling between different medium environments (air and water) must face temperature fluctuations in the equipment and battery pack caused by the temperature difference of the medium. Specifically, water bodies usually promote faster heat dissipation due to their higher thermal conductivity. In contrast, the temperature changes in the air medium are slower.

[0003] During operation, when a drone using a traditional battery pack is lowered from the air into the water, the high thermal conductivity of the water may cause the drone battery pack to cool down quickly, but it is difficult to remove the accumulated heat of the internal battery pack; on the contrary, when the drone rises from the water into the air, the internal temperature of the battery pack may rise more rapidly due to the relatively low thermal conductivity of the air. This long-term high temperature environment causes significant damage to the drone's battery pack, that is, it is unable to effectively discharge the heat generated by the battery pack cells during flight or charging, resulting in a longer cooling time for the cells and accelerated battery aging. This phenomenon poses additional challenges to the design and operation of cross-media drones. Utility Model Content

If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0033] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0034] Drone technology, with its ease of operation and high efficiency, has become one of the cutting-edge technologies that attracts a wide range of users. The convenient operation mode and excellent mission execution efficiency of this technology have enabled it to be widely used and recognized in many industries. Drones have demonstrated their huge application potential and significant advantages in many aspects such as agricultural precision fertilization, building structure inspection, environmental monitoring, and emergency rescue. In particular, cross-media drones can quickly switch and adapt between different media such as air and water, providing innovative solutions for performing complex tasks in multiple environments. The technological progress of this cross-media drone has further expanded the scope of application of drones in complex and changing environments and has great potential.

[0035] There is a problem with existing UAV battery pack cell holders or devices, which requires special optimization of the battery management system to ensure the stability and long-term operation of the equipment under different environmental conditions. In view of this, it is urgent to propose a UAV battery pack that can quickly dissipate heat and cool down in various media environments.

[0036] Reference Figures 1 to 3 The embodiment of the present application provides a battery module 100 for a cross-medium drone, specifically including a sealed shell 140, a battery pack and a heat dissipation pipe 120. At least one row of battery packs is arrayed in the sealed shell 140. One row of battery packs has a plurality of battery cells 130. There is a gap between adjacent battery cells 130 for the heat dissipation pipe 120 to pass through. A plurality of heat dissipation pipes 120 are arranged between the two ends of the battery cell 130. Each battery cell 130 is in contact with the same heat dissipation pipe 120. At least one quarter of the side surface of each battery cell 130 is in contact with the heat dissipation pipe 120. At least two first ports 121 and two second ports 122 are respectively arranged at the two ends of the heat dissipation pipe 120. The first port 121 is connected to one side of the sealed shell 140, and the second port 122 is connected to the other side of the sealed shell 140.

[0037] Both ends of the sealed shell 140 are provided with a medium inlet and outlet 144 for docking with the first port 121 and the second port 122. The setting of the first port 121 and the second port 122 also connects the heat dissipation pipe to the sealed shell 140, and can further conduct heat to the sealed shell 140, thereby expanding the heat dissipation through the sealed shell 140. However, the main heat dissipation of the present application still relies on the heat dissipation pipe 120. The medium flowing in the heat dissipation pipe 120 takes away the heat conducted to the heat dissipation pipe 120. Because the heat dissipation pipe 120 is wound between each battery cell 130, and because the heat dissipation pipe 120 fits the battery cell 130, the heat generated by the battery cell 130 during use can be effectively conducted to the heat dissipation pipe 120.

[0038] Compared with the prior art, the present application rearranges the heat pipe 120, which ensures that the battery cell 130 has sufficient contact area with the heat pipe 120 on the one hand, and reduces the space occupied by the arrangement of the heat pipe 120 on the other hand. On this basis, the heat dissipation effect is also ensured, so that the volume of the entire battery module can be made compact. Furthermore, when the battery module of the present application is used in a cross-medium drone, the first port 121 or the second port 122 should be located at the end of the forward direction of the drone, so that external media such as air or water can flow through the heat pipe 120 to the surface of the battery cell 130, and the heat conducted from the battery cell 130 to the heat pipe 120 by the flowing medium is taken out of the battery module, thereby achieving effective and stable heat dissipation and cooling, reducing the cooling time of the battery cell, and slowing down the aging of the battery.

[0039] The above-mentioned heat pipe 120 design enables drones to undertake longer and more intensive missions, improves their reliability, and thus broadens their practicality in various industries. By optimizing the structural layout and heat dissipation, drones show higher durability and resistance, which helps to perform long-term missions under harsh conditions, and expands the scope of application of drones in various fields.

[0040] In some embodiments, when a row of battery packs is arranged in an array in the sealed shell 140 (not shown in the figure, Figure 1 The picture shows two rows of battery packs, but combined with Figure 1 The specific structure can be understood and known), different sides of two adjacent battery cells 130 are wound by the heat dissipation tube 120. That is to say, between two adjacent battery cells 130, the heat dissipation tube 120 is first wound around one side of one battery cell 130, and then wound around the side of the other battery cell 130. The two battery cells 130 are wound around different sides by the same heat dissipation tube 120. In this way, some gaps are left to reduce the accumulation of heat in local positions, and heat conduction is also facilitated, effectively improving the heat dissipation effect.

[0041] In other embodiments, Figure 1As shown, when two rows of battery packs are arranged in an array in the sealed shell 140, the heat dissipation tubes 120 are wound around the battery cells 130 of the same row of battery packs at intervals, and the battery cells 130 of the two rows of battery packs wound around by the same heat dissipation tube 120 are not adjacent. Specifically, after the same heat dissipation tube 120 is wound around the first battery cell 130 of the first row of battery packs, it is then wound around the second battery cell 130 of the second row of battery packs. The next time, the heat dissipation tube 120 is wound around the third battery cell 130 of the first row of battery packs, and then the fourth battery cell 130 of the second row of battery packs. The subsequent windings of the battery cells 130 are similar, and will not be repeated. Therefore, the battery cells 130 of two different rows of battery packs wound around by the same heat dissipation tube 120 are not adjacent, so that the reasonable winding of the heat dissipation tube 120 is achieved, and the winding length of the heat dissipation tube 120 is also saved, effectively reducing the cost.

[0042] Further, such as Figure 1 As shown, one battery cell 130 is wound around at least half of the heat dissipation tube 120. Figure 7 As shown, when two adjacent heat dissipation tubes 120 are translated to the same plane, the two heat dissipation tubes 120 are symmetrically arranged. Reasonable winding can improve the heat dissipation efficiency and avoid the situation of local uneven heat dissipation.

[0043] Further, such as Figure 6 As shown, the heat dissipation tube 120 has a plurality of first bending portions 123 and second bending portions 124 adapted to the side shape of the battery cell 130, and the first bending portions 123 and the second bending portions 124 are arranged at intervals, with the first bending portions 123 facing one side of the heat dissipation tube 120 and the second bending portions 124 facing the other side of the heat dissipation tube 120. Such reasonable winding can improve the heat dissipation efficiency and also save the use of the heat dissipation tube 120.

[0044] In some embodiments, Figure 1 As shown, two positioning frames 110 for fixing the battery cells 130 are arranged in the sealed shell 140, one positioning frame 110 fixes one end of the battery cell 130, and the other positioning frame 110 fixes the other end of the battery cell 130. Specifically, the positioning frame 110 is provided with a card slot 111 for clamping the battery cell 130, and the card slot 111 is used to realize the interval arrangement of the battery cells 130.

[0045] like Figure 4 and Figure 5 As shown, the present application also provides a battery module, including the above-mentioned cross-medium drone battery module 100 and a module compartment 210, the module compartment 210 is provided with at least two chambers for accommodating a sealed shell 140, and after all the cross-medium drone battery modules 100 are docked in the chamber, all the cross-medium drone battery modules 100 are connected in series.

[0046] In view of the problem that the battery structure of the existing drone is fixed and the battery capacity cannot be adjusted according to the estimated workload, the above-mentioned modular capacity customizable module compartment 210. The module compartment 210 adopts a highly flexible modular design concept, allowing the user to quickly adjust the capacity and output characteristics of the battery pack according to the energy requirements of a specific task. By introducing interchangeable battery modules, the dynamic configurability of the battery capacity is achieved, thereby optimizing the flight endurance and operating efficiency of the drone. Under this framework, each battery module is managed by a sophisticated electronic control unit (ECU) to ensure that effective power balance and distribution can be achieved between battery cells under different configurations. In addition, by adopting a battery management system (BMS), the key parameters such as the charging and discharging process, temperature, and voltage of the battery pack are further monitored and adjusted in real time to improve the safety and reliability of the entire system. The modular battery pack architecture not only improves the flexibility and adaptability of the drone system, but also greatly extends the battery life and reduces maintenance costs by optimizing battery utilization efficiency and cooperating with a cross-medium heat dissipation system.

[0047] At the same time, the battery module with battery modules can realize the adjustable capacity of the battery modules, which is convenient for dynamic configuration and optimizes the endurance and operating efficiency. Furthermore, when the battery modules with optimized heat dissipation structure are used in combination or charged, they can achieve effective and stable heat dissipation and cooling, reduce the cooling time of the battery cells, and slow down the aging of the battery.

[0048] like Figure 4 and Figure 5 As shown, the sealed shell 140 is provided with a docking port 143, and the chamber is provided with a receiving port 211 at a position corresponding to the docking port 143. When the cross-medium drone battery module 100 is completely placed in the chamber, the docking port 143 is plugged and connected with the receiving port 211, so that the power of the cross-medium drone battery module 100 can be regulated and called by the module compartment 210.

[0049] Furthermore, the sealing shell 140 is provided with positioning grooves 141 and limiting protrusions 142 on both sides, and the chamber is provided with positioning convex strips matching the positioning grooves 141 and positioning concave parts matching the limiting protrusions 142. The above design can realize the rapid docking of the cross-medium drone battery module 100 with the chamber.

[0050] Further, such as Figure 8 and Fig. 9 As shown, the present application also provides a drone having the above-mentioned cross-medium drone battery module 100 or battery module. Figure 8 and Fig. 9 Only the combination of the cross-medium UAV battery module 100 and the UAV is shown, and the combination of the battery module and the UAV is not shown. However, those skilled in the art can make an adaptive design based on the existing drawings, such as Fig. 9 The power compartment 301 of the drone body 300 can be modified to match the size of the module compartment 210. In the embodiment of the present application, Fig. 9 The power compartment 301 of the drone body 300 can be adapted to be plugged into the sealed shell 140 .

[0051] The battery modules or battery packs mentioned above enable drones to undertake longer and more intensive missions, improving their reliability and thus broadening their applicability in various industries. By optimizing the structural layout and heat dissipation, drones exhibit higher durability and resistance, helping to perform long-term missions in harsh conditions, expanding the scope of application of drones in various fields.

[0052] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present application.
