[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] It should be noted that in the description of the present invention, the terms "first" and "second" are only used to facilitate the description of different components, and cannot be understood as indicating or implying a sequential relationship, relative importance, or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0020] Unmanned aerial vehicles, referred to as "drones", are unmanned aerial vehicles that are controlled by radio remote control equipment and self-contained program control devices. Existing unmanned aerial vehicles are equipped with a large number of heating devices. The heat accumulated in the unmanned aerial vehicle is exported to the outside of the unmanned aerial vehicle through the heat dissipation module to prevent the unmanned aerial vehicle from failing to work normally due to heat accumulation. The heat dissipation module is set at the bottom of the unmanned aerial vehicle to prevent the unmanned aerial vehicle from entering water during flight. The accumulation of water in the heat dissipation module affects the heat dissipation effect. In order to meet their own design requirements, some unmanned aerial vehicles have cancelled the heat dissipation module. This method limits the power of the equipment, and equipment with high heat generation cannot be selected, sacrificing the performance of the unmanned aerial vehicle and failing to improve the performance of the equipment to a higher level among products of the same level. Some unmanned aerial vehicles forcibly set the heat dissipation module on the top or side of the unmanned aerial vehicle. The unmanned aerial vehicle with this design has a low waterproof and dustproof level and cannot meet the waterproof design requirements. This limits the use environment of the equipment and cannot be used in rainy weather, thereby limiting the market for the use of the equipment. Therefore, most unmanned aerial vehicles can only set the heat dissipation module at the bottom to prevent water from entering the heat dissipation module, which limits the freedom of design of the unmanned aerial vehicle and restricts the internal space layout of the unmanned aerial vehicle.

[0021] In view of this, the present disclosure provides an unmanned aerial vehicle, wherein a spacer is provided to separate the accommodating cavity into at least a heat dissipation cavity and an electronic cavity containing electronic devices, a water inlet and a water outlet are provided in the accommodating cavity to form a drainage channel, and the spacer constitutes at least part of the inner wall of the drainage channel, the heat generated by the electronic device can be conducted to the heat dissipation cavity through the spacer, and the water in the heat dissipation cavity can be discharged from the unmanned aerial vehicle along the drainage channel. Thus, the mechanism components can be arranged on the top of the unmanned aerial vehicle without sacrificing the waterproof level and working performance of the unmanned aerial vehicle.

[0022] In the following, some embodiments of the present invention are described in detail in conjunction with the accompanying drawings. In the case where there is no conflict between the embodiments, the following embodiments and features in the embodiments can be combined with each other.

The mechanism component may be, for example, a battery compartment or a central body on the unmanned aerial vehicle. The mechanism component is provided with a receiving cavity 10 for receiving the electronic device. An isolating member 20 is provided in the receiving cavity 10. The isolating member 20 divides the receiving cavity 10 into at least a heat dissipation cavity 13 and an electronic cavity 14 for receiving the electronic device.

[0026] The accommodating cavity 10 is provided with a water inlet 11 and a water outlet 12 to form a drainage channel.

The heat generated by the electronic device can be conducted to the heat dissipation cavity 13 through the isolation member 20, and the moisture in the heat dissipation cavity 13 can be discharged from the mechanism components along the drainage channel.

[0027] In this embodiment, the mechanism components of the unmanned aerial vehicle include a shell, which is used to protect and carry the electronic components of the unmanned aerial vehicle. A housing 10 is formed inside the shell, and an isolator 20 is arranged inside the housing 10. Schematically, the isolator 20 is in a shape of a straight plate or an L-shaped plate. The edge of the isolator 20 is connected to the inner wall of the shell, and the isolator 20 and the shell are enclosed to form a heat dissipation cavity 13 and an electronic cavity 14.

One end of the heat-conducting element contacts the heat-generating part of the electronic device, and the other end of the heat-conducting element is disposed in the heat-dissipating cavity 13, so that the heat generated by the electronic device can be conducted to the heat-dissipating cavity 13 through the isolating member 20. A water outlet 12 is disposed at the bottom of the heat-dissipating cavity 13, so that the water entering the heat-dissipating cavity 13 can be discharged from the mechanism components through the water outlet 12.

When the heat dissipation cavity 13 has multiple lowest points, the water outlet 12 can be set at a position where there is no electronic cavity 14 below. There is no electronic cavity 14 below the lowest point of the heat dissipation cavity 13, so that the water entering the heat dissipation cavity 13 can be directly discharged from the mechanism components through the water outlet 12. When the heat dissipation cavity 13 and the electronic cavity 14 are stacked up and down, that is, the electronic cavity 14 is provided below the lowest point of the heat dissipation cavity 13, the water outlet 12 is set at the bottom of the electronic cavity 14, that is, the water outlet 12 is set at the bottom of the shell forming the electronic cavity 14.

[0030] Please refer to the attached Figure 3 Furthermore, the heat dissipation cavity 13 and the electronic cavity 14 are located on opposite sides of the isolation member 20. Figure 3 For example, the heat dissipation cavity 13 is located above the isolating member 20, and the electronic cavity 14 is located below the isolating member 20. Schematically, the isolating member 20 is generally in the shape of a plate, and has two faces that are separated from each other. One face of the isolating member 20 constitutes a part of the inner wall of the accommodating cavity 10, and the other face of the isolating member 20 constitutes a part of the inner wall of the electronic cavity 14. It should be pointed out that this example does not limit the state of the isolating member 20. The isolating member 20 can be arranged horizontally so that the heat dissipation cavity 13 and the electronic cavity 14 are arranged in a stacked manner; or it can be arranged at a certain angle to the horizontal so that the heat dissipation cavity 13 and the electronic cavity 14 are arranged in parallel left and right.

The isolation member 20 is provided with a drain port 21, one end of the drainage channel is connected to the drain port 21, and the other end of the drainage channel is connected to the water outlet 12. The drainage member 30 is used to guide the water in the heat dissipation cavity 13 to be discharged from the mechanism component through the drain port 21, the drainage channel and the water outlet 12.

[0032] Schematically, the isolating member 20 is generally arranged horizontally, the heat dissipation cavity 13 and the electronic cavity 14 are stacked up and down, the heat dissipation cavity 13 is above the electronic cavity 14, and a drain port 21 is provided at the bottom of the heat dissipation cavity 13, that is, provided on the isolating member 20.

[0033] Please refer to the attached Figures 1 to 3 Furthermore, the drainage component 30 includes a first drainage component 31 and a second drainage component 32. The first drainage component 31 extends downward from the edge of the drain port 21 and is connected to the drain port 21. The second drainage component 32 extends upward from the edge of the water outlet 12 and is connected to the water outlet 12. The first drainage component 31 and the second drainage component 32 are connected to form the inner wall of the drainage channel.

[0034] Schematically, the drainage member 30 includes a first drainage member 31 and a second drainage member 32.

The drainage channel is composed of the pipe of the first drainage member 31 and the pipe of the second drainage member 32.

The drainage channel formed by the first drainage member 31 and the second drainage member 32 has a stable structure, and the first drainage member 31 and the second drainage member 32 are convenient to connect and assemble.

[0035] Furthermore, the outer diameter of the first drainage component 31 is smaller than the inner diameter of the second drainage component 32, and a first sealing member 33 is sandwiched between the first drainage component 31 and the second drainage component 32. For example, the first drainage component 31 and the second drainage component 32 are connected by a snap-fit ​​method, the outer diameter of the first drainage component 31 is smaller than the inner diameter of the second drainage component 32, a part of the structure of the first drainage component 31 can be sleeved in the second drainage component 32, and a first sealing member 33 is provided between the part of the first drainage component 31 sleeved in the second drainage component 32 and the second drainage component 32, and the first sealing member 33 can be a rubber sealing ring or a silicone sealing ring. When the first sealing member 33 is between the first drainage component 31 and the second drainage component 32, it is in a compressed state, so as to be sealed and connected with the outer peripheral surface of the first drainage component 31 and the inner peripheral surface of the second drainage component 32.

[0036] Furthermore, an outer sealing groove 34 is provided on the outer circumference of the first drainage component 31, and the first sealing member 33 is provided between the inner circumference of the second drainage component 32 and the outer sealing groove 34.

[0037] In some optional implementations, the drainage member 30 includes a drain pipe (not shown), one end of which is connected to the drain port 21, and the other end of which is connected to the water outlet 12. For example, when the drainage member 30 needs to pass through the electronic cavity 14, the drainage member 30 can adopt the structural form of a drain pipe. It can be understood that a drainage channel is formed in the body of the drain pipe, and the two ends of the drain pipe are respectively connected to the drain port 21 and the water outlet 12. The drain pipe can be made of a plastic hose or a metal pipe. Based on the above, the use of a drain pipe as the drainage member 30 has a simple structure, strong flexibility, and is easy to produce.

[0038] In some optional implementations, the water outlet 12 is disposed at the bottom of the electronic cavity 14.

[0039] In some optional implementations, the mechanism component includes a cover body 41 and a bottom shell 42, and the cover body 41 and the bottom shell 42 are butt-jointed to form the accommodating cavity 10. For example, the edge of the cover body 41 and the edge of the bottom shell 42 may be butt-jointed to form the accommodating cavity 10.

Schematically, the portion of the isolating member 20 facing the cover 41 cooperates with the cover 41 to form the heat dissipation cavity 13, and the portion of the isolating member 20 facing the bottom shell 42 cooperates with the bottom shell 42 to form a part of the electronic cavity 14. The inner wall of the isolating member 20 and the cover 41 serves as the inner wall of the heat dissipation cavity 13, and the inner wall of the isolating member 20 and the bottom shell 42 serves as a part of the inner wall of the electronic cavity 14.

[0041] Furthermore, the isolating member 20 includes a heat dissipation substrate 22 and a second sealing member 23, and the heat dissipation substrate 22 is sealedly connected to the cover body 41 through the second sealing member 23 to form a heat dissipation cavity 13; the heat generated by the electronic device in the electronic cavity 14 can be conducted to the heat dissipation cavity 13 through the heat dissipation substrate 22. Schematically, the edge of the heat dissipation substrate 22 is connected to the inner wall of the cover body 41, and the second sealing member 23 is sandwiched between the edge of the heat dissipation substrate 22 and the inner wall of the cover body 41, so that the moisture in the heat dissipation cavity 13 cannot flow out through the gap between the edge of the heat dissipation substrate 22 and the inner wall of the cover body 41, and a certain sealing performance is maintained.

[0042] Furthermore, the cover body 41 is provided with a first matching portion 411, and the heat dissipation substrate 22 is provided with a second matching portion 24. The first matching portion 411 and the second matching portion 24 cooperate to fix the heat dissipation substrate 22 to the cover body 41.

During installation, the top of the flange 412 abuts against the second seal 23. The top of the flange 412 is the part of the flange 412 that first enters the slot 25. The top of the flange 412 squeezes the second seal 23, so that the first matching portion 411 is sealed and connected with the second matching portion 24.

[0044] In some optional implementations, the cover 41 is provided with an air inlet 27 and an air outlet 414, the isolating member 20 includes a fan, the fan can rotate to dissipate heat, and the drainage channel can drain away the moisture entering the heat dissipation cavity 13 from the air inlet 27 or the air outlet 414.

The fan is electrically connected to the control circuit in the electronic cavity 14, and the air outlet end of the fan is arranged toward the air outlet 414 to accelerate the air flow and improve the heat dissipation efficiency.

[0045] Furthermore, the isolating member 20 further includes a heat sink 26, which is used to conduct heat to the heat generated by the electronic device in the electronic cavity 14. The heat sink 26 is disposed on the heat dissipation substrate 22, and the heat sink 26 is connected to the electronic device in the electronic cavity 14 through a heat conducting element, so that the heat generated by the electronic device is conducted to the heat sink 26, and then the heat is exchanged to the air by the heat sink 26. The heat sink 26 is disposed between the air outlet of the fan and the air outlet 414, and the heat exchanged to the air by the heat sink 26 is discharged to the outside of the heat dissipation cavity 13 through the air outlet 414.

The main body 261 and the electronic device can conduct heat. The sheet 262 is disposed on the upper surface of the main body 261, and the sheet 262 extends upward from the upper surface of the main body 261. A plurality of sheets 262 are arranged in parallel, and the sheet 262 is a long strip of metal plate, and the material is a metal with good thermal conductivity such as copper or aluminum. The length direction of the sheet 262 is parallel to the airflow direction, and a plurality of sheets 262 are provided with spacing to facilitate heat exchange. When water enters the heat sink 13, the water flowing through the sheet 262 can take away the heat on the heat sink 26.

[0047] In some optional implementations, the unmanned aerial vehicle includes two drains 21 and a drainage member 30 adapted to the two drains 21, the two drains 21 are connected to two drainage channels, the two drainage channels are connected to the water outlet 12, and the two drains 21 are arranged on the left and right sides of the roll axis of the unmanned aerial vehicle. Schematically, the drainage member 30 has two interfaces that can be connected to the two drains 21, and the two drainage channels collect and introduce water into the water outlet 12. The drainage member 30 can be implemented by a structure such as a Y-shaped tube body or a V-shaped tube body. The two drains 21 are arranged on the left and right sides of the roll axis of the unmanned aerial vehicle. Based on the above, by setting two drains 21, the drainage efficiency of the accumulated water in the heat dissipation cavity 13 can be accelerated, thereby reducing the possibility of accumulated water accumulating on the left or right side of the roll axis of the unmanned aerial vehicle, and ensuring the safety of the unmanned aerial vehicle's mechanical components when the unmanned aerial vehicle turns left or right.

[0048] In some optional implementations, two drain ports 21, two water outlets 12, and a drainage member 30 adapted to the two drain ports 21 are included, and the two ends of the two drainage channels are respectively connected to the two water outlets 12 and the two drain ports 21, and the two drain ports 21 are arranged on the left and right sides of the roll axis of the unmanned aerial vehicle. Schematically, independent drainage channels are respectively provided on the left and right sides of the roll axis of the unmanned aerial vehicle, and the two drain ports 21 are arranged on the left and right sides of the roll axis of the unmanned aerial vehicle. When the unmanned aerial vehicle turns left or right, the mechanical parts of the unmanned aerial vehicle will tilt to the left or right. If there is water accumulation in the heat dissipation cavity 13, the water will accumulate on the left or right side of the roll axis of the unmanned aerial vehicle. Providing two water outlets 12 can speed up the drainage efficiency.

[0049] In some optional implementations, a drain hole 413 is provided at a position of the cover body 41 away from the water outlet 12, and an air outlet 414 is provided above the cover body 41 corresponding to the water outlet 12. The cover body 41 is also provided with a drain hole 413, and the drain hole 413 corresponds to an end of the isolation member 20 away from the drain outlet 21. For example, the drain hole 413 can be provided at one end along the roll axis direction of the unmanned aerial vehicle, and the drain outlet 21 can be provided at the other end along the roll axis direction of the unmanned aerial vehicle. When the unmanned aerial vehicle is flipped over, the air outlet 414 and the drain hole 413 can also drain water, and water can be drained in various postures, which is conducive to improving drainage efficiency.

[0050] Furthermore, in some implementations, the lower edge of the drain hole 413 is flush with the bottom surface of the isolating member 20, so that the water in the heat dissipation cavity 13 can be discharged from the drain hole 413. The lower edge of the drain hole 413 is flush with the bottom surface of the isolating member 20. When the UAV flies toward the drain hole 413, the end of the UAV where the drain hole 413 is located sinks and the end where the water outlet 12 is located rises. At this time, the water in the heat dissipation cavity 13 can be discharged from the drain hole 413.

[0051] In some optional implementations, the outer surface of the cover body 41 is provided with a concave first groove 43, the first groove 43 has a first groove wall 431 and a second groove wall 432, the first groove wall 431 and the second groove wall 432 are arranged opposite to each other, the first groove wall 431 is provided with an air outlet 414, and the second groove wall 432 is used to block the airflow outside the mechanism component from pouring into the heat dissipation cavity 13 from the air outlet 414. Schematically, the first groove 43 is concave from the top of the cover body 41 to form the first groove wall 431 and the second groove wall 432, the air outlet 414 is arranged on the first groove wall 431, and when the unmanned aerial vehicle is flying, the second groove wall 432 can block the airflow outside the mechanism component from pouring back into the heat dissipation cavity 13 from the air outlet 414.

[0052] Furthermore, the first groove wall 431 and the second groove wall 432 may be arranged in a “V” shape. The bottoms of the first groove wall 431 and the second groove wall 432 are connected, so that the cross-sectional shape of the first groove wall 431 and the second groove wall 432 is substantially arranged in a V shape.
