[0039] The utility model provides an indoor drone 1000.

[0040] See also Figure 1 、 Figure 2 and Figure 3 To achieve the above objectives, the present invention provides an indoor drone 1000 comprising:

[0041] The body 1 is provided with a receiving cavity 11 and a first air outlet 12 communicating with the receiving cavity 11;

[0042] The rotor arm 2 includes an arm body 21 and a propeller 22. The arm body 21 is fixedly connected to the body 1. The arm body 21 is provided with an air duct 211 communicating with the accommodating chamber 11. The propeller 22 is provided on the arm body 21. An air inlet connected to the air duct 211 is provided on the outer wall of the arm body 21 facing the propeller 22.

[0043] The heat sink 3 includes a main body 31 disposed in the accommodating cavity 11 and an air guide portion 32 connected to the main body 31; the main body 31 has a mounting cavity 314 and a ventilation cavity 313 surrounding the mounting cavity 314; the main body 31 is provided with a second air outlet 315 communicating with the ventilation cavity 313 or the mounting cavity 314; the second air outlet 315 is provided corresponding to the first air outlet 12; at least a portion of the air guide portion 32 extends into the air duct 211, and the air guide portion 32 is provided with an air guide channel connecting the air duct 211 and the ventilation cavity 313; and

[0044] The heating device, at least part of its structure is accommodated in the mounting cavity 314 .

[0045] It should be noted that the location of the first air outlet 12 can be flexibly selected based on actual needs. Based on the normal flight posture of the drone: 1) When located on the top of the fuselage 1, it can utilize the natural rise of hot air to efficiently exhaust hot air and reduce the impact on flight stability; 2) If located on the side of the fuselage 1, it can form a synergistic effect with the airflow generated by the propeller 22, further improving heat dissipation efficiency; 3) When located at the bottom, the larger available space at the bottom allows for a larger air outlet, resulting in better heat dissipation. This multi-position design provides a flexible solution for heat dissipation needs in different application scenarios.

[0046] As the core component connecting the fuselage 1 and the propeller 22, the rotor arm 2's structural design must ensure both stable operation of the propeller 22 and efficient heat dissipation. Specifically, the arm 21 of the rotor arm 2 not only provides a stable mounting platform for the propeller 22, ensuring balance and operating efficiency during flight, but also requires a hollow interior to accommodate the air duct 211 that connects to the fuselage 1's accommodating chamber 11. Therefore, the arm 21 must be made of high-strength, lightweight materials. The propeller 22 is typically mounted at the end of the arm 21 and consists of a built-in motor, a rotating shaft, and blades. The motor is fixed inside the arm 21 and connected to the blades via a rotating shaft. The other end of the rotating shaft extends from the air inlet to mount the blades. When the blades rotate, the strong airflow generated enters the air duct 211 through the air inlet on the arm 21, and is then directed into the fuselage 1's accommodating chamber 11, effectively removing heat generated by the internal heat-generating components. This integrated design ensures both flight performance and improved heat dissipation. In order to improve the rotation stability of the blades, a shaft sleeve seat can be set in the air duct 211 near the air inlet. The shaft sleeve seat is fixedly connected to the inner wall of the air duct 211 through multiple radially distributed connecting arms to form a central support structure. The rotating shaft is supported by rolling bearings in the shaft sleeve seat to achieve high-precision rotation. The spacing between the connecting arms ensures that the airflow can smoothly enter the air duct 211 from the air inlet, thereby enhancing the rotation rigidity and stability of the blades while taking into account the ventilation efficiency and not affecting the normal operation of the cooling system.

[0047] The heat sink 3 can be designed in a variety of structural forms to meet different needs. For example, the heat sink 3 can be a box-shaped structure. This structure is simple and easy to manufacture. It can be designed to be very small as needed to accommodate only regular heating devices such as batteries and / or high-power chips, or it can fill the entire accommodating cavity as much as possible to install more and larger heating devices. Of course, the heat sink 3 can also be a special-shaped structure that adapts to the shape of the body 1. This design can better utilize the space inside the body 1 and improve space utilization. It can be customized according to the shape of the body 1 and the position of the heating device to ensure that the heat sink 3 fits tightly with the internal structure of the body 1 while providing sufficient heat dissipation space for the heating device. In addition, the heat sink 3 can also adopt a multi-channel structure, with the installation cavity 314 located in the center, and the ventilation cavity 313 divided into multiple independent channels arranged around the installation cavity 314. Each channel is provided with heat dissipation fins to improve the heat dissipation efficiency, which is suitable for high-power heating devices. To further improve the heat dissipation effect, the heat sink 3 can also be combined with heat pipes to assist in heat dissipation. The main body 31 adopts an aluminum alloy structure and is provided with multiple heat pipes inside. One end of the heat pipe is in contact with the heating device in the installation cavity 314, and the other end is connected to the heat dissipation fins, which effectively improves the heat dissipation efficiency and is suitable for heating devices that generate high heat. In any case, the specific size and shape of the heat sink 3 can be determined according to the size of the drone's accommodating cavity 11, the layout of the heating device, and the amount of air entering the air duct 211.

[0048] In summary, the indoor drone 1000 provided by the present invention effectively solves the overheating problem of the motherboard and chip by using the rotor arm 2 as an air duct 211 and disposing a heat sink 3 in communication with the air duct 211 within the body 1. Specifically, the body 1 of the drone is provided with a housing 11 and a first air outlet 12 in communication therewith. The rotor arm 2 is provided with an air duct 211 in communication with the housing 11, and an air inlet is provided on the outer wall of the arm 21 directly opposite the propeller 22, so that the airflow generated by the rotation of the propeller 22 can enter the air duct 211 through the air inlet. The air guide portion 32 of the heat sink 3 extends into the air duct 211, and the air flow in the air duct 211 is guided by the air guide channel of the air guide portion 32 into the ventilation cavity 313 surrounding the mounting cavity 314 within the main body 31, thereby removing heat from the heating device disposed in the mounting cavity 314. The heat-carrying airflow passes through the second air outlet 315 and is discharged from the first air outlet 12. In the present invention, on the one hand, the existing space of the rotor arm 2 is cleverly utilized, and the airflow generated by the propeller 22 is used to directly dissipate heat for the internal components, which can simplify the heat dissipation structure; on the other hand, the airflow is caused to flow around the installation cavity 314 through the ventilation cavity 313 to take away part of the heat of the heating component, which can significantly improve the heat dissipation efficiency and avoid overheating of the heating component. It not only improves the working stability of the indoor drone 1000, but also extends the service life of the indoor drone 1000 and reduces the risk of high-temperature failure and damage.

[0049] See also Figure 3 、 Figure 4 and Figure 5 In one embodiment, the main body 31 includes:

[0050] a box body 311 having a receiving cavity; and

[0051] The partition assembly 312 includes a first partition 3121, a second partition 3122, and a third partition 3123 connected end to end. The first partition 3121, the second partition 3122, and the third partition 3123 enclose opposite walls of the accommodating chamber to form an installation chamber 314. The sides of the first partition 3121, the second partition 3122, and the third partition 3123 facing away from the installation chamber 314 enclose the walls of the accommodating chamber to form a ventilation chamber 313. The third partition 3123 defines a first air outlet 316.

[0052] Among them, the outer wall of the box body 311 away from the second partition 3122 is provided with a second air outlet 315 connected to the installation cavity 314, and the second air outlet 315 is arranged away from the first air outlet, and the first partition 3121 and the third partition 3123 are arranged opposite to each other along the first direction.

[0053] It needs to be explained that, according to the shape of the box body 311, the cavity wall of the accommodating cavity refers to all the side walls that enclose the accommodating cavity, including multiple side walls located in the up, down, left, right, front and back directions, and the opposite side walls of the accommodating cavity refer to two side walls in relative positions among all the side walls, that is, the front and back side walls, the left and right side walls or the upper and lower side walls. Such a setting can make the ventilation cavity 313 have three connected chambers in the upper, lower and left directions. In the process of airflow entering the installation cavity 314 along the ventilation cavity 313, the surrounding environment of the installation cavity 314 can be cooled, which is equivalent to always placing the installation cavity 314 in a relatively low temperature environment, and the cooling effect is excellent.

[0054] Furthermore, the first partition 3121 is provided on the upper side of the housing 311, the third partition 3123 is provided on the lower side of the housing 311 relative to the first partition 3121, and the second partition 3122 is provided on the left side. Thus, the air guide 32 can be connected to either the upper or lower chamber, depending on the position of the rotor arm 2 and the structure of the ventilation chamber 313. Furthermore, the third partition 3123 defines a first air inlet, and the second air outlet 315 is located away from the first air inlet. This allows airflow from the ventilation chamber 313 below the mounting chamber 314 to enter the mounting chamber 314 through the first air inlet. As the airflow enters, the hot air is gradually "pressed" (i.e., rises) toward the second air outlet 315. Simultaneously, because the first air outlet 12 is connected to the external environment, a negative pressure suction effect is generated at the location of the first air outlet 12, allowing airflow to be quickly discharged through the second air outlet 315 corresponding to the first air outlet 12, further improving the heat dissipation capability of the indoor drone 1000.

[0055] See also Figure 4 and Figure 5 In one embodiment, the partition assembly 312 further includes a fourth partition 3124 and a fifth partition 3125 disposed in the ventilation cavity 313. The fourth partition 3124 and the fifth partition 3125 are connected to opposite sides of the second partition 3122 in the first direction. The fourth partition 3124 and the fifth partition 3125 are respectively provided with a second air outlet 317 and a third air outlet 318.

[0056] Among them, the first partition 3121, the fourth partition 3124 and the cavity wall of the accommodating cavity are jointly arranged to form the first device cavity 313a; the fourth partition 3124, the second partition 3122, the fifth partition 3125 and the cavity wall of the accommodating cavity are combined to form the guide cavity 313c; the fifth partition 3125, the third partition 3123 and the cavity wall of the accommodating cavity are combined to form the second device cavity 313b; the first device cavity 313a, the guide cavity 313c and the second device cavity 313b are connected in sequence to form the ventilation cavity 313; the first device cavity 313a and the second device cavity 313b are both used to install electrical components.

[0057] In this embodiment, electrical components that generate slightly more heat can be placed in the first device cavity 313a with a lower temperature, and electrical components that generate slightly less heat can be placed in the second device cavity 313b with a higher temperature. This not only makes full use of the ventilation cavity 313, but also plays a role in balancing heat distribution, avoiding the situation where there are too many electrical components in the installation cavity 314 and some electrical components cannot be effectively cooled.

[0058] In order to simplify the structure of the partition assembly 312 and reduce the production cost, please refer to Figure 4 and Figure 5In one embodiment, the first partition 3121, the fourth partition 3124, and the fifth partition 3125 are all electrical installation panels. This design allows the heating device to be directly fixed via the electrical installation panel, which not only saves installation structure, but also makes the installation of the heating device more stable and facilitates maintenance and replacement.

[0059] In another embodiment, the first partition 3121, the fifth partition 3125, and the fourth partition 3124 can also be directly used as dustproof partitions to protect and prevent dust from the electrical components in the box body 311. This multifunctional design not only simplifies the structure of the heat sink 3 and reduces the number of parts, but also improves the overall performance and reliability of the heat sink 3, achieving the effect of reducing costs and increasing efficiency.

[0060] See also Figure 1 and Figure 2 In one embodiment, a mounting opening is opened on the top wall of the body 1, and the box body 311 is inserted into the accommodating cavity 11 from the mounting opening; the indoor drone 1000 includes a fixing structure, which is provided in the accommodating cavity 11 and is used to fix the box body 311 in the accommodating cavity 11.

[0061] In this embodiment, the box body 311 is inserted into the accommodating cavity 11 through a slot. This design makes the installation process of the heat sink 3 simple and quick, and facilitates quick replacement and maintenance. A fixing structure is provided in the accommodating cavity 11, which is used to firmly fix the box body 311 in the accommodating cavity 11, ensuring that the heat sink 3 will not loosen or shift due to vibration during the operation of the drone. Through this design, the heat sink 3 can stably provide heat dissipation function for the electrical components inside the drone, while preventing dust from entering the box body 311, protecting the electrical components from dust erosion. This multifunctional design of a single structural component not only improves the installation efficiency of the heat sink 3, but also reduces production costs and enhances the reliability and maintainability of the drone.

[0062] It should be noted that, in one embodiment, the fixing structure can be a combination of a card slot and a card block. For example, a card slot is provided on the inner side wall of the accommodating chamber 11, and a card block matching the card slot is provided on the side of the box body 311. When the box body 311 is inserted into the accommodating chamber 11, the card block is embedded in the card slot, thereby achieving fixation. This structure is simple and easy to operate, and convenient for maintenance. In another embodiment, the fixing structure can also be a locking screw. After the box body 311 is inserted into the accommodating chamber 11, the box body 311 is fixed by the locking screw. In other embodiments, the fixing structure can also be made of magnetic material, for example, a magnet is provided on the inner side wall of the accommodating chamber 11, and the box body 311 is adsorbed and fixed in the accommodating chamber 11 by magnetic force. This design facilitates quick installation and disassembly, and also ensures the stability of the box body 311 during operation. Of course, the fixing structure can also use a sticky material, such as providing double-sided tape or a sticky gasket on the inner wall of the accommodating cavity 11, and using the sticky material to fix the box body 311 within the accommodating cavity 11. This design is simple and low-cost, and is suitable for fixing lightweight heat sinks 3 and small heat sinks 3. It is not difficult to see that the specific structure and shape of the heat sink 3 can be selected and adjusted according to actual application needs and performance requirements to achieve optimal fixing effect and maintenance convenience.

[0063] Of course, to prevent dust from entering the interior of the box body 311, in one embodiment, the main body 31 further includes a cover that covers the box body 311 and seals the mounting opening. The cover and the box body can be connected using a snap-fit ​​connection or screw fastening. In another embodiment, a filter can be provided on the outside of the first air outlet 12.

[0064] In one embodiment, at least one fixing hole is provided on the bottom wall of the box body 311, and the fixing structure includes at least one elastic clip, and the at least one elastic clip includes a fixing section and a deformation section, the fixing section is fixedly connected to the bottom wall of the accommodating cavity 11, and the deformation section has a guide slope, which is used to guide the deformation section to be inserted into the fixing hole.

[0065] It should be noted that the deformation section may be a rubber protrusion or a rubber hook.

[0066] In this embodiment, when the box body 311 is inserted into the accommodating cavity 11, the deformable segment undergoes elastic deformation under the guidance of the guide bevel and eventually snaps into the fixing hole, thereby firmly fixing the box body 311 in the accommodating cavity 11. To remove the box body 311, it is only necessary to apply a force opposite to the insertion direction so that the deformable segment overcomes the elastic deformation force and escapes from the fixing hole, thereby achieving quick disassembly. This fixing method has a simple structure, low cost, and is easy to install and disassemble quickly, which improves the convenience of maintenance. At the same time, it ensures the stability of the heat sink 3 during the operation of the drone, avoids loosening or displacement due to vibration, and improves the reliability and service life of the drone.

[0067] See also Figure 3 In one embodiment, the air guide portion 32 is an air guide pipe 321, which includes a connecting pipe section 3211 and a hose section 3212. One end of the connecting pipe section 3211 is detachably connected to the box body 311, and the hose section 3212 is connected to the end of the connecting pipe section 3211 away from the box body 311; the indoor drone 1000 also includes a magnetic attraction structure, which includes a first magnetic attraction portion and a second magnetic attraction portion that attract each other. The first magnetic attraction portion and the second magnetic attraction portion are respectively arranged on the air duct 211 and the end of the hose section 3212 away from the connecting pipe section 3211.

[0068] In this embodiment, the use of hose segment 3212 provides greater flexibility during installation of the air duct 321, enabling it to adapt to different installation positions and angles, making it easier to adjust within limited space. This flexibility allows the air duct 321 to bend and twist to a certain extent during installation, making it easier to align with the air duct 211 and other components, reducing the difficulty of alignment during installation. Furthermore, magnetic attraction allows the hose segment 3212 to be quickly connected to the air duct 211 without the need for complex mechanical fixing devices. The magnetic structure ensures a more stable connection between the hose segment 3212 and the air duct 211, maintaining a good seal and airflow guidance even when the drone vibrates during operation. In summary, the design of the hose segment 3212 and the magnetic structure makes the air duct 321 more convenient when maintenance or replacement is required. The flexibility of the hose segment 3212 allows it to be easily removed from the air duct 211 without damage, while the magnetic structure ensures a quick connection during removal and reinsertion. This design not only improves maintenance convenience but also reduces maintenance time and costs.

[0069] See also Figure 1 and Figure 2 In one embodiment, the indoor drone 1000 includes at least two rotor arms 2; the heat sink 3 includes at least two air guides 32, and the at least two air guides 32 are respectively provided corresponding to the plurality of rotor arms 2.

[0070] In this embodiment, at least two air guides 32 are provided corresponding to at least two rotor arms 2, so that the airflow generated by each rotor arm 2 can be effectively guided into the ventilation cavity 313 of the heat sink 3 through the corresponding air guide 32. This ensures uniform distribution and efficient utilization of the airflow, thereby significantly improving heat dissipation efficiency. This design allows the heat sink 3 to be adapted for use with two-wing or multi-wing drones.

[0071] It should be noted that, in order to avoid turbulence, a curved baffle may be provided in the ventilation cavity 313 to change the direction of the airflow at the outlet of the corresponding air guide portion 32 so that the direction of the airflow guided by each air guide portion 32 is consistent with the direction of the airflow in the ventilation cavity 313.

[0072] Of course, when the heat sink 3 is relatively small, the heat sink 3 can also be designed with only one air guide portion 32 to connect with one rotor arm 2. At this time, multiple heat sinks 3 can also be set inside the body 1 to correspond to multiple rotor arms 2 respectively, thereby achieving the effects of guiding ventilation and heat dissipation at the same time.

[0073] In one embodiment, the indoor drone 1000 further includes a guide fan, which is disposed in the ventilation cavity 313 to accelerate the air flow in the ventilation cavity 313 to further improve the heat dissipation efficiency.

[0074] Of course, fans provided with some of the heating devices installed in the first device cavity 313 a , the second device cavity 313 b or the installation cavity 314 can also be used as guide fans.

[0075] In another embodiment, the body 1 and the rotor arm 2 are integrally formed. This means that the accommodating cavity and the air duct 211 are also integrally formed, eliminating the connection gaps and assembly errors that exist in a separate design. This not only improves the airflow guidance efficiency and reduces airflow loss in the duct, but also enhances the overall performance of the heat dissipation system.

[0076] The present invention also provides an indoor drone system 1000, comprising the indoor drone 1000 and a charging station, indoor positioning system, and charging device that cooperate with the indoor drone 1000. The specific structure of the indoor drone 1000 is similar to the above-mentioned embodiments. Since the indoor drone system 1000 utilizes all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be detailed here.

[0077] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
