[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1

[0030] Reference Figures 1-7 A quick-release battery compartment for a multi-rotor drone, comprising:

[0031] The silo body has an internal storage space. The silo body includes a silo plate 1, a top plate 3 and a side plate 6. The side wall of the silo plate 1 is connected to a protective cover 101. The interior of the protective cover 101 is provided with several ventilation cylinders 103 and heat absorption blocks 104.

[0032] The battery panel 2 is located on one side of the compartment. A card holder 13 and a quick-release connector 14 are provided on one side of the battery panel 2. A fastening seat 12 is connected to the side wall of the battery panel 2.

[0033] Furthermore, each of the bin plate 1, top plate 3, and side plate 6 is provided with a pair. One side of the bin plate 1 is provided with a plurality of linear array sinking slots 102. The sinking slots 102 are detachably connected to the protective cover 101. The side wall of the protective cover 101 is fixedly connected to the ventilator 103. The outer wall of the ventilator 103 is fixedly connected with a partition plate 105. The heat-absorbing block 104 is filled in the gap between the protective cover 101 and the ventilator 103. There is a gap between the heat-absorbing block 104 and the inner wall of one end of the sinking slot 102.

[0034] It should be noted that the linear array of recessed slots 102 on one side of the silo plate 1 serves as both the mounting carrier for the protective cover 101 and the basic channel for airflow in and out. The protective cover 101 and the recessed slots 102 are detachably connected, facilitating the replacement and maintenance of the heat absorption block 104, while ensuring a tight connection between the protective cover 101 and the silo plate 1 to prevent airflow leakage or structural loosening. Several vents 103 fixed inside the protective cover 101 are evenly distributed along the array direction of the recessed slots 102, and the partition plates 105 fixed to their outer walls divide the internal space of the protective cover 101 into several... An independent "heat absorption chamber" ensures that the composite phase change heat absorption block 104 can be evenly filled in the gap between the protective cover 101 and the vent 103, avoiding the accumulation or uneven distribution of the heat absorption block 104 and ensuring uniform heat dissipation. The gap reserved between the heat absorption block 104 and the inner wall of one end of the sinking slot hole 102 forms an "airflow buffer channel", which not only provides space for airflow to enter and exit, but also avoids the heat absorption block 104 from directly blocking the sinking slot hole 102. At the same time, it reserves buffer space for the slight volume expansion of the heat absorption block 104 during phase change, preventing stress damage to the protective cover 101 or the silo plate 1 due to thermal expansion and contraction.

[0035] When the battery is operating normally and the temperature has not reached the phase change point of the composite phase change material (approximately 40°C), the structure primarily relies on "ventilation and convection cooling," utilizing the density difference between the airflow from the drone's flight and the hot airflow inside the cabin to create a natural circulation: During drone flight, external cold air enters the reserved gap through the recessed slot 102 of the cabin plate 1, and then enters the cabin interior through the hollow channel of the ventilator 103; simultaneously, the arc-shaped slot 8 of the side plate 6, the elongated hole 5 of the top plate 3, and the oblique waist-shaped hole 4 form auxiliary ventilation openings to further replenish the cold air; the cold air flows through the cabin... When inside the body, it comes into contact with the surface of the solar panel 2 and the power battery module, absorbs heat and becomes hot airflow; under the action of density difference, the hot airflow is discharged from the chamber through the reserved gap of another set of sinking slot holes 102 and the channel of the ventilator 103, forming a ventilation cycle of introduction, heat exchange and discharge; the partition plate 105 on the outer wall of the ventilator 103 not only divides the heat absorption chamber, but also guides the airflow to flow along a fixed path, avoiding the decrease in heat dissipation efficiency caused by airflow turbulence, while increasing the contact area between the airflow and the surface of the heat absorption block 104, laying the foundation for subsequent phase change heat absorption.

[0036] When the battery operates under high load (such as during prolonged operation), the ambient temperature is too high, or the ventilation and heat dissipation channels are blocked (such as due to dust blockage or low-altitude, low-speed flight), causing the internal temperature of the compartment to exceed 40°C (the phase change point of the composite phase change material), the composite phase change heat absorber block 104 (paraffin wax plus expanded graphite, mass ratio 7:3) activates the "phase change heat absorption" mode to quickly reduce the internal temperature of the compartment: the heat generated by the battery is transferred to the heat absorber block 104 through the compartment plate 1 and the protective cover 101, or directly to the heat absorber block 104 through the ventilation airflow. When the temperature of the heat absorber block 104 reaches 40°C, the internal paraffin wax begins to change from a solid state to a viscous gel state (due to expansion). The expanded graphite adsorption process initiates a phase change process. During this process, the composite phase change material rapidly reduces the internal temperature of the chamber by absorbing a large amount of latent heat. Even if ventilation and heat dissipation fail, the battery temperature can be controlled within a safe threshold in a short time, preventing the battery from degrading or failing due to high temperature. The expanded graphite in the composite phase change material has a porous network structure, which on the one hand adsorbs and locks the molten paraffin into a non-flowing gel to prevent paraffin leakage; on the other hand, the expanded graphite has good thermal conductivity, which can quickly transfer the local high heat inside the chamber to the entire heat absorption block 104, achieving uniform heat absorption and avoiding the accumulation of local hot spots.

[0037] When the battery load decreases and the temperature drops below 40°C, the paraffin in the composite phase change heat absorber 104 gradually solidifies from a viscous gel to a solid state, releasing the heat absorbed previously. The heat released during solidification is carried away by external cold air through ventilation circulation, completing the cycle of heat absorption and release, allowing the heat absorber 104 to return to its initial state and prepare for the next phase change heat absorption. The supporting effect of expanded graphite ensures that the heat absorber 104 maintains structural integrity after solidification, preventing delamination, flow, or breakage due to repeated phase changes. At the same time, the reserved expansion gaps prevent structural deformation caused by solidification contraction, ensuring the long-term stable operation of the entire heat dissipation structure. Paraffin provides high latent heat for efficient heat absorption, while expanded graphite solves the paraffin phase change flow problem and improves thermal conductivity. The 7:3 mass ratio balances heat absorption efficiency and structural stability, perfectly meeting the lightweight and miniaturized requirements of drone battery compartments.

[0038] Reference Figures 1-4 Furthermore, the top plate 3 has an elongated hole 5 on its side wall, and one of the top plates 3 has an oblique waist-shaped hole 4 on its side wall. The top plate 3 is connected to a fastener 9. The top plate 3 is inserted into the compartment plate 1 through the elongated hole 5. A reinforcing rod 16 is provided between the two compartment plates 1. One end of the reinforcing rod 16 is fixedly connected to the fastening seat 12, and the other end of the reinforcing rod 16 is fixedly connected to the corresponding compartment plate 1. The two ends of one side plate 6 are respectively inserted into the side wall of the compartment plate 1, and the other side plate 6 is hinged to one of the top plates 3. One side of the side plate 6 is snapped into the fastener 9. The side wall of the side plate 6 has an arc-shaped slot 8. A handle 7 is fixedly connected to the side wall of the side plate 6. The side wall of the battery plate 2 has a mounting hole 10 and a mounting hole 21. The mounting hole 211 is key-shaped. The side wall of the battery plate 2 is detachably connected to the card seat 13. The card seat 13 is slidably connected to the quick-release connector 14. The card seat 13 is connected to a fixing rod 15.

[0039] It should be noted that:

[0040] The elongated hole 5 on the side wall of the top plate 3 serves as a connection interface with the cabin plate 1. During assembly, the corresponding protruding end of the cabin plate 1 is inserted into the elongated hole 5. The tight fit between the hole wall and the protrusion achieves lateral positioning, limiting the relative displacement of the top plate 3 and the cabin plate 1 in the horizontal direction. At the same time, the long axis of the elongated hole 5 is consistent with the assembly direction of the cabin body, ensuring guidance during assembly and initially fixing the positions of the two through the friction between the hole wall and the insertion end, providing a foundation for subsequent reinforcement. The reinforcing rod 16 added between the two cabin plates 1 adopts a connection method with fixed ends. One end is rigidly connected to the fastening seat 12 on the side wall of the battery plate 2, and the other end is fixed to the corresponding cabin plate 1, forming a support structure spanning the interior of the cabin body. Its core function is to offset the lateral force generated by vibration and airflow impact during flight, prevent the insertion point of the cabin plate 1 and the top plate 3 from loosening, and at the same time transfer the force of the battery plate 2 to the reinforcing rod 16 through the fastening seat 12, and then distribute it to the two cabin plates 1 on both sides to achieve force balance and improve the overall structural stability.

[0041] One side panel 6 is fixed to the compartment panel 1 by "two-end plug-in". During assembly, the two ends of the side panel 6 are inserted into the reserved slots on the side wall of the compartment panel 1 to achieve longitudinal positioning and close one side of the compartment. The other side panel 6 is connected to one of the top panels 3 by "hinged". It can be rotated around the hinge axis to facilitate opening the compartment for battery maintenance or component repair. When closed, the side panel 6 is engaged with the buckle 9 on the top panel 3 on one side. The elastic engagement structure of the buckle 9 locks the side panel 6 to prevent it from falling off due to vibration during flight, and finally forms a closed and stable compartment structure.

[0042] The key-shaped mounting hole 211 adopts a design of large hole for introduction and small hole for locking. During assembly, the head of the fastener is first inserted into the large hole end of mounting hole 211, and then slid along the long axis to the small hole end. The initial positioning is achieved by the fit between the small hole wall and the fastener thread, which prevents the fastener from shifting during assembly. Mounting hole 10 serves as an auxiliary fixing hole, which works with mounting hole 211 to form a multi-point fixing. The fastener locks the battery panel 2 to the internal structure of the cabin, restricting the displacement of the battery panel 2 in the vertical and horizontal directions and ensuring that the battery panel 2 and the cabin remain relatively stationary during flight.

[0043] The card holder 13 is detachably connected to the side wall of the battery panel 2 and adopts a sliding fit design with the quick-release connector 14. The front and rear positions of the card holder 13 can be adjusted along the reserved slide rail on the side wall of the battery panel 2 according to the interface position of the mounted equipment to ensure that the quick-release connector 14 is precisely aligned with the equipment interface. After adjustment, the card holder 13 is fixed to the battery panel 2 by fasteners to limit its sliding displacement. The fixing rod 15 connected to the card holder 13 passes through the corresponding holes of the card holder 13 and the quick-release connector 14 laterally to form an axial locking force, preventing the quick-release connector 14 from separating from the card holder 13 under the gravity of the mounted equipment or the vibration of flight.

[0044] The arc-shaped slots 8 on the side wall of the side panel 6 provide ventilation channels for the interior of the cabin, forming airflow circulation with the recessed slots 102 of the cabin plate 1 and the ventilator 103 to aid in heat dissipation. On the other hand, the arc-shaped contour design avoids sharp edges and corners, reducing wind resistance during flight, while also providing space for the operation of the handle 7, improving the human-machine interaction experience. The handle 7 on the side wall of the side panel 6 provides a force point for the handling and disassembly of the cabin, making it easy for operators to quickly move the cabin or open the hinged side panel 6. The latch 9 on the top plate 3 engages with the hinged side panel 6, allowing the side panel 6 to be closed and opened simply by pressing and flicking the latch 9, which is linked with the operation of the handle 7 to improve the overall ease of operation.

[0045] It should be noted that the specific model and specifications need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
