Description

Technical Field

[0001] This disclosure relates to the field of unmanned aerial vehicle (UAV) technology, and more particularly to a UAV nose and a UAV. Background Technology

[0002] With the rapid development of microelectronic systems, powerful, high-performance, and miniaturized electronic components have emerged. However, high performance means high heat generation, and the smaller the electronic component, the more severe the challenge to heat dissipation. Therefore, solving and mitigating heat dissipation issues and the resulting reliability risks has become a high priority. Drones are high-tech products integrating a variety of high-performance electronic components. To reduce weight, drones generally use composite materials and polymers as the main shell and structural materials for the drone nose. However, these materials have very low thermal conductivity, which is not conducive to heat conduction and heat dissipation. Therefore, one of the areas with the greatest threat to heat dissipation is the drone nose.

[0003] To achieve heat dissipation for drones, related technologies employ a method of placing a vent at each opposite end of the drone's shell. These two vents connect to the internal space of the shell, forming a heat dissipation duct. Cooling fans are then positioned at the vents in this duct, causing airflow to move along the axial direction of the drone's shell, achieving forced convection cooling within the shell. However, because the air inlets are located at the front or side of the drone, this presents greater challenges in terms of waterproofing and dustproofing. Furthermore, this heat dissipation layout has relatively low efficiency, and it cannot meet the cooling requirements of the more powerful drone nose with higher heat consumption.

[0031] The technical solution provided in this disclosure has the following advantages compared with the prior art:

[0032] The UAV nose section provided in this disclosure achieves good ventilation inside the nose section by providing a first air inlet and a first air outlet on the nose section shell that communicate with the internal space of the nose section shell, thereby dissipating heat from the heat-generating components distributed throughout the nose section shell. Furthermore, a first heat dissipation component is provided inside the nose section shell for dissipating heat from a first functional component (which may specifically include the main heat-generating components within the nose section shell). The first heat dissipation component has internal heat dissipation channels that communicate with the first air inlet and the second air outlet located at the bottom of the nose section shell, thereby achieving heat dissipation from the main heat-generating components (such as the main processing chip) within the nose section shell. This design addresses the heating issues of the main heat-generating components within the nose cone housing, as well as other heat-generating components distributed throughout the housing. This heat dissipation layout effectively isolates these components, improving the convective heat transfer coefficient and thus achieving higher heat dissipation efficiency. Furthermore, the first air inlet, second air inlet, and second air outlet are all located at the bottom of the nose cone housing, effectively enhancing waterproofing and dustproofing. This satisfies both waterproofing and dustproofing requirements, as well as the heat dissipation needs of more powerful and energy-intensive drone nose cones. This heat dissipation layout is more applicable to drone nose cones of various layouts and sizes, offers better waterproofing and dustproofing, and provides higher heat dissipation efficiency.

[0033] The drone disclosed herein achieves good ventilation inside the drone shell by providing a first air inlet and a first air outlet that communicate with the internal space of the drone shell, thereby dissipating heat from the heat-generating components distributed throughout the drone shell. Furthermore, a first heat dissipation component is provided inside the drone shell for dissipating heat from a first functional component (which may specifically include the main heat-generating components within the drone shell). The first heat dissipation component has internal heat dissipation channels that communicate with the first air inlet and the second air outlet located at the bottom of the drone shell, thereby achieving heat dissipation from the main heat-generating components (such as the main processing chip) within the drone shell. This design solves the heating problems of the main heat-generating components inside the drone shell and other heat-generating components distributed throughout the drone shell. This heat dissipation layout can achieve reasonable isolation of heat-generating components inside the drone shell, improve the convective heat transfer coefficient of most heat-generating components, and thus achieve higher heat dissipation efficiency. At the same time, the first air inlet, the second air inlet, and the second air outlet are all located at the bottom of the drone shell, which can effectively improve the waterproof and dustproof effect, thus meeting both the waterproof and dustproof requirements and the heat dissipation needs of the more powerful and heat-consuming drone nose. This heat dissipation layout has higher applicability to drone noses of various layouts and sizes, better waterproof and dustproof effect, and higher heat dissipation efficiency.

[0051] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0052] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0053] Reference Figure 1 and Figure 2 As shown, this embodiment provides a drone nose section 100, including a nose section housing 1. The nose section housing 1 is provided with a first air inlet 1101 and a first air outlet 1102 that communicate with the internal space of the nose section housing 1. By providing the first air inlet 1101 and the first air outlet 1102, better ventilation is achieved inside the nose section housing 1, thereby dissipating heat from the heat-generating components distributed throughout the inside of the nose section housing 1.

[0054] The first air inlet 1101 is located at the bottom of the nose housing 1, or in other words, the first air inlet 1101 is located below the nose housing 1, allowing outside air to enter the nose housing 1 from below. This arrangement effectively improves the waterproof and dustproof performance. The first air outlet 1102 is located at the tail end of the nose housing 1, or in other words, along the normal flight direction of the UAV, the first air outlet 1102 is located at the end of the nose housing 1 relatively close to the tail. This arrangement facilitates the smooth exhaust of air inside the nose housing 1 through the first air outlet 1102, which is beneficial to improving the convective heat transfer effect of the air inside the nose housing 1.

[0055] It should be understood that, in order to dissipate heat from the heat-generating components distributed throughout the interior of the nose housing 1, the first air inlet 1101 can be located at the bottom of the nose housing 1, relatively close to the front end. Preferably, the first air inlet 1101 is located on the central axis of the nose housing 1 of the drone nose, or two first air inlets 1101 are arranged side by side at the bottom of the nose housing 1, and the two first air inlets 1101 are symmetrically arranged with respect to the central axis of the nose housing 1. Since the rear end of the drone nose usually needs to connect to components such as the fuselage frame 15, the first air outlet 1102 can be located at the tail end of the nose housing 1, relatively close to the side, or in other words, the first air outlet 1102 can be located at the tail end of the nose housing 1, offset from the central axis of the drone nose. Of course, depending on the actual situation, the first air inlet 1101 and the first air outlet 1102 can be set in other reasonable positions of the head housing 1. For example, the first air outlet 1102 can be set at the bottom of the head housing 1, which can also achieve the convection heat transfer effect inside the head housing 1.

[0056] Reference Figure 3 and Figure 4 As shown, a cooling fan 1105 is provided at the first air outlet 1102. The cooling fan 1105 is used to guide external airflow into the head housing 1 through the first air inlet 1101 and to guide the air inside the head housing 1 out of the head housing 1 through the first air outlet 1102. This achieves forced convection heat transfer inside the head housing 1 using the cooling fan 1105. Compared with natural convection cooling, adding a cooling fan 1105 can effectively improve the heat dissipation effect. The cooling fan 1105 can be an axial fan, with the airflow direction horizontal to the ground and exhausting outwards from the head housing 1.

[0057] To enhance waterproofing and dustproofing, a first air inlet dustproof net 1106 is installed at the first air inlet 1101, and a first air outlet dustproof net 1107 is installed at the first air outlet 1102. The first air inlet dustproof net 1106 and the first air outlet dustproof net 1107 can be honeycomb-shaped dustproof nets, or they can be selected and designed according to actual needs.

[0058] To further enhance waterproofing and dustproofing, preferably, the opening of the first air inlet 1101 faces downwards. This ensures that even in strong headwinds or crosswinds during drone flight, raindrops and dust are less likely to enter the nose housing 1 via the first air inlet 1101, effectively improving waterproofing and dustproofing. Furthermore, to achieve the downward-facing opening of the first air inlet 1101, the bottom of the nose housing 1 has a flat area, and the first air inlet 1101 is located within this flat area. Even further, this flat area has a recessed portion formed by the indentation from the outer bottom of the nose housing 1 towards the inner bottom, and the first air inlet 1101 is located within this recessed portion. Of course, by placing the first air inlet 1101 at the bottom of the head housing 1, the head housing 1 provides better waterproof and dustproof performance even if the opening of the first air inlet 1101 is not downward (e.g., it is tilted at a certain angle) due to the shielding effect of the head housing 1, compared to placing the first air inlet 1101 at the front or side of the head housing 1.

[0059] Reference Figure 2 and Figure 3 As shown, the head housing 1 is provided with a first functional component 2 and a first heat dissipation component 3 for dissipating heat from the first functional component 2. The first heat dissipation component 3 is in contact with the first functional component 2. A heat dissipation duct is formed inside the first heat dissipation component 3. The bottom of the head housing 1 is provided with a second air inlet 1103 and a second air outlet 1104 that communicate with the heat dissipation duct.

[0060] Specifically, the first functional component 2 may include the main heat-generating elements inside the nose housing 1. For example, the first functional component 2 may include a main processing chip and a main processing chip circuit board 202 for mounting the main processing chip. The main processing chip and the main processing chip circuit board 202 generate a lot of heat when the UAV is working. Simply relying on convection heat exchange with the air in the internal space of the nose housing 1 cannot meet the heat dissipation requirements. Therefore, the embodiments of this disclosure provide a first heat dissipation component 3 for dissipating heat from the first functional component 2 inside the nose housing 1. The first heat dissipation component 3 is in contact with the first functional component 2. Preferably, the first heat dissipation component 3 is in close contact with the first functional component 2 to transfer the heat of the first functional component 2 to the first heat dissipation component 3. The interior of the first heat dissipation component 3 forms a heat dissipation duct independent of the internal space of the nose housing 1. A second air inlet 1103 and a second air outlet 1104 communicating with the heat dissipation duct are provided at the bottom of the nose housing 1.

[0061] In practice, outside air enters the heat dissipation duct of the first heat dissipation component 3 through the second air inlet 1103, carrying away the heat transferred from the first functional component 2 to the first heat dissipation component 3, and then is discharged to the outside of the head housing 1 through the second air outlet 1104, thus effectively dissipating heat from the first heat dissipation component 3 and improving the heat dissipation efficiency of the first functional component 2.

[0062] The second air inlet 1103 and the second air outlet 1104 are both located at the bottom of the head housing 1, or in other words, the second air inlet 1103 and the second air outlet 1104 are both located below the head housing 1, so that outside air enters the head housing 1 from below and is discharged to the outside of the head housing 1 from below. This can effectively improve the waterproof and dustproof effect and reduce the risk of water droplets / dust entering the head housing 1 through the second air inlet 1103 or the second air outlet 1104.

[0063] Reference Figure 2 and Figure 3 As shown, to better improve the waterproof and dustproof effect, a second air inlet dustproof net 1108 is installed at the second air inlet 1103, and a second air outlet dustproof net 1109 is installed at the second air outlet 1104. The second air inlet dustproof net 1108 and the second air outlet dustproof net 1109 can be honeycomb-shaped dustproof nets or long strip perforated dustproof nets, or can be selected and designed according to actual needs.

[0064] To further enhance waterproofing and dustproofing, the second air inlet 1103 preferably faces downwards. This ensures that even in strong headwinds or crosswinds during drone flight, raindrops and dust are less likely to enter the nose housing 1 via the upward flow of the second air inlet 1103, effectively improving waterproofing and dustproofing. Furthermore, to achieve this downward-facing orientation, the bottom of the nose housing 1 has a flat area, and the second air inlet 1103 is positioned within this area. The orientation of the second air outlet 1104 has a relatively small impact on waterproofing and dustproofing; preferably, the second air outlet 1104 also faces downwards. Of course, even if the second air inlet 1103 is not positioned downwards (e.g., tilted at a certain angle) due to the shielding effect of the nose housing 1, it still provides better waterproofing and dustproofing than if it were positioned at the front or side of the nose housing 1.

[0065] The drone nose cone provided in this embodiment features a first air inlet 1101 and a first air outlet 1102 on the nose cone housing 1, which communicate with the internal space of the nose cone housing 1. Preferably, a cooling fan 1105 is installed at the first air outlet 1102, enabling good ventilation inside the nose cone housing 1 and thus dissipating heat from the heat-generating components distributed throughout the nose cone housing 1. A first heat dissipation component 3 for dissipating heat from the first functional component 2 is installed inside the nose cone housing 1. The first heat dissipation component 3 has a heat dissipation duct inside, which communicates with the first air inlet 1101 and the second air outlet 1104 located at the bottom of the nose cone housing 1, thereby dissipating heat from the main heat-generating components (such as the main processing chip) inside the nose cone housing 1. This design facilitates heat dissipation, addressing the heating issues of the main heat-generating components within the nose cone housing 1 and other components distributed throughout it. This heat dissipation layout effectively isolates the heat-generating components within the nose cone housing 1, improving the convective heat transfer coefficient of most components and thus achieving higher heat dissipation efficiency. Simultaneously, the first air inlet 1101, the second air inlet 1103, and the second air outlet 1104 are all located at the bottom of the nose cone housing 1, effectively enhancing waterproofing and dustproofing. This satisfies both waterproofing and dustproofing requirements, as well as the heat dissipation needs of more powerful and thermally efficient drone nose cones. This heat dissipation layout offers greater applicability to drone nose cones of various layouts and sizes, better waterproofing and dustproofing, and higher heat dissipation efficiency.

[0066] Reference Figure 6 and Figure 7 As shown, the first heat dissipation component 3 includes a centrifugal fan 301 and a heat dissipation pipe 302 connected between the second air inlet 1103 and the second air outlet 1104. The heat dissipation pipe 302 is in close contact with the first functional component 2, and heat dissipation fins are provided inside the heat dissipation pipe 302. The air outlet of the centrifugal fan 301 is connected to the inlet of the heat dissipation pipe 302 to form an independent heat dissipation air duct between the air inlet of the centrifugal fan 301 and the air outlet of the heat dissipation pipe 302. The air inlet of the centrifugal fan 301 is connected to the second air inlet 1103, and the air outlet of the heat dissipation pipe 302 is connected to the second air outlet 1104, so as to better transfer the heat of the first functional component 2 to the heat dissipation pipe 302, and exchange heat with the air entering the heat dissipation pipe 302 through the heat dissipation fins provided inside the heat dissipation pipe 302, quickly removing the heat of the heat dissipation pipe 302 and the heat dissipation fins, thereby achieving high-efficiency heat dissipation of the first functional component 2.

[0067] The heat dissipation pipe 302 includes a horizontal pipe section 3021 and an arc-shaped pipe section 3022. One end of the horizontal pipe section 3021 is connected to one end of the arc-shaped pipe section 3022. The other end of the horizontal pipe section 3021 forms the inlet of the heat dissipation pipe 302, and the other end of the arc-shaped pipe section 3022 forms the outlet of the heat dissipation pipe 302. The outlet direction of the heat dissipation pipe 302 is perpendicular to the inlet direction of the heat dissipation pipe 302.

[0068] Specifically, under the suction of the centrifugal fan 301, outside air enters the centrifugal fan 301 through the second air inlet located at the bottom of the head housing 1. Under the centrifugal force of the centrifugal fan 301, the air flows from vertical to horizontal and then exits the centrifugal fan 301 into the heat dissipation pipe 302. The heat dissipation pipe 302 consists of a horizontal pipe section 3021 and a 90° arc-shaped pipe section 3022. The heat dissipation pipe 302 converts the horizontal airflow at the outlet of the centrifugal fan 301 into a vertical airflow, and finally discharges it to the outside of the head housing 1 through the second air outlet 1104 located at the bottom of the head housing 1.

[0069] It should be noted that, in the specific processing of the heat dissipation pipe 302 and the heat dissipation fins located in the heat dissipation pipe 302, a surrounding plate can be set around the conventional electronic heat sink or electronic radiator, so that the entire electronic heat sink forms a pipe-like structure that is closed on all sides and open at both ends. Multiple heat dissipation fins on the heat sink are arranged along the central axis of the pipe formed by the surrounding plate, and a flow guide gap is formed between two adjacent heat dissipation fins to allow air to pass through.

[0070] The heat dissipation pipe 302 is connected to the first functional component 2 by solder paste or thermally conductive adhesive to achieve better adhesion and heat conduction.

[0071] To ensure the airtightness of the heat dissipation duct itself, the air outlet of the centrifugal fan 301 is sealed and fitted with the inlet of the heat dissipation pipe 302 without any gaps. If there are gaps, they can be sealed with materials such as acetate tape.

[0072] To ensure a sealed connection between the heat dissipation duct and the second air inlet 1103 and the second air outlet 1104 of the head shell 1, an elastic sealing ring 303 is provided between the air inlet of the centrifugal fan 301 and the second air inlet 1103. One end of the elastic sealing ring 303 is fitted with the air inlet of the centrifugal fan 301, and the other end is fitted with the second air inlet 1103, forming a sealed air duct to ensure that no air flows into the head shell 1 of the UAV head.

[0073] In practice, the elastic sealing ring 303 can be made of foam. The foam has a ring-shaped structure, with its upper surface conforming to the air inlet of the centrifugal fan 301 and its lower surface conforming to the second air inlet 1103. The foam can be fixed to the air inlet of the centrifugal fan 301 by means of bonding or other fixing methods, forming an integral part with the first heat dissipation component 3.

[0074] In some embodiments, refer to Figure 6 As shown, the first functional component 2 includes a main processing chip circuit board 202, a main processing chip upper shell 203, and a main processing chip lower shell 201. The main processing chip circuit board 202 is mounted on the main processing chip lower shell 201. The main processing chip upper shell 203 is mounted on top of the main processing chip circuit board 202 and is fixedly connected to the main processing chip lower shell 201. The main processing chip lower shell 201 and the main processing chip upper shell 203 are used to support and protect the main processing chip circuit board 202.

[0075] Furthermore, the first heat dissipation component 3 can be fixedly connected with the first functional component 2 to form an integral module. The heat dissipation pipe 302 of the first heat dissipation component 3 is fitted with the lower shell 201 of the main processing chip. The centrifugal fan 301 of the first heat dissipation component 3 may not be in direct contact with the lower shell 201 of the main processing chip.

[0076] In some embodiments, refer to Figures 1 to 3 As shown, the housing includes a lower housing 11, a front housing 12, and an upper housing 13. The front housing 12 and the lower housing 11 or the upper housing 13 can be made as one piece or separated into two parts.

[0077] Specifically, the lower housing 11 of the machine head is provided with mounting screw holes 1111 and mounting bayonet 1112. The upper housing 13 and the lower housing 11 of the machine head can be fixed together through the mounting screw holes 1111, the mounting bayonet 1112, and fasteners. The outer surface of the upper housing 13 can be made of a highly reflective material, which has a high reflectivity and a low absorptivity, making it suitable for absorbing less solar radiation during outdoor operations.

[0078] Reference Figure 4 and Figure 5 As shown, the first air inlet 1101, the first air inlet dustproof net 1106, the cooling fan 1105, the first air outlet 1102, the first air outlet dustproof net 1107, the second air inlet 1103, the second air inlet dustproof net 1108, the second air outlet 1104, and the second air outlet dustproof net 1109 mentioned in the above embodiment can all be set on the lower housing 11 of the head unit; in order to ensure the symmetry of the structure on the lower housing 11 of the head unit, decorative holes 1110 and other structures can be set on the lower housing 11 of the head unit at positions symmetrical to the second air outlet 1104.

[0079] Reference Figure 3 As shown, the head housing 1 is provided with a second functional component 4 and a second heat dissipation component 5 for dissipating heat from the second functional component 4. The second heat dissipation component 5 is fitted to the second functional component 4.

[0080] Specifically, the heat emitted by the heating element in the second functional component 4 can be transferred to the second heat dissipation component 5. The heat of the second heat dissipation component 5 can be carried away by the cold air entering the internal space of the head housing 1 through the first air inlet 1101 during the flow inside the head housing 1. After heat exchange, the internal air of the head housing 1 is discharged to the outside of the head housing 1 through the first air outlet 1102, thereby achieving heat dissipation for the second functional component 4.

[0081] It should be understood that electronic components within the head housing 1, such as ultrasonic processing chips, laser ranging processing chips, power supplies, UPS, GPS, etc., can be distributed anywhere within the head housing 1 as needed. This disclosure uses the second functional component 4 as an equivalent simplified representation, or it can also be represented as a PCB assembly as an equivalent simplified representation. By providing a second heat dissipation component 5 within the head housing 1 for dissipating heat from the second functional component 4, some of the high-heat-generating electronic components of the second functional component 4 can achieve uniform temperature and heat dissipation through the second heat dissipation component 5.

[0082] Continue to refer to Figure 3 As shown, the second heat dissipation component 5 includes a heat sink 51, which is fitted to the second functional component 4. Specifically, the heat sink 51 can be mounted on the lower surface of the second functional component 4 via a connector. (Refer to...) Figure 3 and Figure 8 As shown, the heat sink 51 has multiple heat dissipation fins 5101 spaced apart on the side facing away from the second functional component 4, forming an airflow channel between adjacent heat dissipation fins 5101. The airflow channel is arranged parallel to the axis of the cooling fan 1105 (specifically, an axial fan) inside the head housing 1. That is, the direction of the heat dissipation fins 5101 is parallel to the axis of the cooling fan 1105, or in other words, the direction of the heat dissipation fins 5101 is parallel to the airflow direction of the forced convection fan. This effectively increases the airflow velocity across the heat sink 51, thereby increasing the convective heat transfer coefficient of the second functional component 4 and achieving higher heat dissipation efficiency.

[0083] Reference Figure 8 and Figure 9The diagram shows the front and back structures of the heat sink 51. Multiple heat dissipation fins 5101 are spaced apart on one side of the heat sink 51, forming an airflow channel between adjacent fins 5101. High-heat-generating electronic components of the second functional component 4 can be evenly cooled and dissipated through the heat sink 51. A heat sink mounting hole 5104 can be provided on the side of the heat sink 51 away from the heat dissipation fins 5101, allowing the heat sink 51 and the second functional component 4 to be fixedly installed through the mounting hole 5104 and connectors. Furthermore, clearance holes 5102 and contact bosses 5103 can be provided on the heat sink 51 according to installation needs. Clearance holes 5102 are used to avoid taller electronic components in the second functional component 4, ensuring smooth assembly of the heat sink 51 and the second functional component 4. Contact bosses 5103 allow the heat sink 51 to contact smaller electronic components in the second functional component 4, ensuring effective heat dissipation through contact conduction.

[0084] Reference Figure 3 and Figure 10 As shown, the drone's nose has a main frame, which includes components such as the nose main support 6, guide plate support 10, guide plate 14, fuselage frame 15, and binocular structure frame 8.

[0085] The lower surface of the main nose support 6 is fixedly connected to the lower nose shell 11, the tail section of the main nose support 6 is fixedly connected to the fuselage frame 15, and the lower surface of the main nose support 6 is fixedly connected to the left and right guide plate supports 10. The main nose support 6 is generally made of materials such as aluminum alloy or magnesium-aluminum alloy, which have high thermal conductivity, high rigidity, and low density, to ensure high structural strength of the entire UAV nose. The second functional component 4 (or PCB component) mentioned above can be installed above the main nose support 6. Specifically, the second functional component 4 and the main nose support 6 can be fixedly connected by a connector 7, which can be a type of copper stud. (Refer to...) Figure 10 As shown, the main support 6 of the machine head is provided with a first mounting hole 602 for assembly and connection with the second functional component 4. The first functional component 2 and the first heat dissipation component 3 mentioned above can be installed below the main support 6 of the machine head, and located between the left and right guide plate supports 10. (Refer to...) Figure 10 As shown, the main support 6 of the machine head is also provided with a second mounting hole 603 for assembly and connection with the fuselage frame 15.

[0086] The main support bracket 6 of the nose is a plate-shaped structural component. It is located inside the nose housing 1 and is mainly used to ensure the overall structural strength of the UAV nose. The main support bracket 6 is parallel (or approximately parallel) to the bottom of the nose housing 1, that is, the main support bracket 6 is parallel (or approximately parallel) to the bottom surface of the lower shell 11 of the nose. In order to allow the cold air entering the nose housing 1 through the first air inlet 1101 to dissipate heat for more electronic components that need heat dissipation, the main support bracket 6 is provided with a vent 601 opposite to the first air inlet 1101. The vent 601 is used to allow some of the cold air passing through the first air inlet 1101 and the first air inlet dustproof net 1106 to pass through the vent 601, so as to enhance the air convection near more electronic components that need heat dissipation inside the nose housing 1 and reduce the shell temperature and junction temperature of the electronic components.

[0087] Reference Figure 10 As shown, the main support 6 of the head is equipped with components such as the binocular structural frame 8. In order to prevent the heat from the heat source (such as the electronic components in the second functional component 4) from being conducted from the main support 6 of the head to the binocular structural frame 8, thereby affecting the sensor accuracy of the binocular structural frame 8, a heat insulation pad 9 is provided between the binocular structural frame 8 and the main support 6 of the head.

[0088] Reference Figure 3 and Figure 10 As shown, the guide plate bracket 10 is located inside the head housing 1 and is fixedly connected to the lower surface of the head main bracket 6. Specifically, there are two guide plate brackets 10, namely the left guide plate bracket and the right guide plate bracket. The guide plate 14 is located on the outer side of the bottom of the head housing 1 and is fixedly connected to the guide plate bracket 10. Specifically, there are two guide plates 14, namely the left guide plate and the right guide plate. The left guide plate 14 is fixedly connected to the left guide plate bracket 10, and the right guide plate 14 is fixedly connected to the right guide plate bracket 10.

[0089] Specifically, the left and right guide plates 14 of this disclosure serve to guide and assist in securing the delivered goods when the UAV is used for delivery missions. The left and right guide plates 14 can be made of materials with high strength and good thermal conductivity, such as aluminum alloy. When heat dissipation requirements are high, the left and right guide plates 14 and their supports 10 can all be heat-conducting components. For example, using aluminum alloy can help transfer heat from the main support 6 of the drone head to the external environment through the left and right guide plate supports 10 and the left and right guide plates 14, utilizing air convection for heat dissipation. If heat dissipation requirements are not high, the left and right guide plates 14 can be made of lightweight, non-shielded materials such as plastic, and internal hardware such as antennas can be added for communication and positioning.

[0090] Reference Figure 2As shown, there are two guide plates 14, which are arranged opposite to each other. The second air inlet 1103 is located between the two guide plates 14, and the second air outlet 1104 is located on the side of one guide plate 14 away from the other guide plate 14. The first air inlet 1101 is located in front of the second air inlet 1103. This arrangement uses the guide plates 14 to separate the second air inlet 1103 and the second air outlet 1104, and the first air inlet 1101 is located in front of the second air inlet 1103, so that the first air inlet 1101 is relatively far away from the second air outlet 1104. This can prevent the hot air discharged from the second air outlet 1104 from being sucked back into the first air inlet 1101 and / or the second air inlet 1103 in certain situations (such as when flying near the ground), thereby ensuring the heat dissipation effect of the drone's nose.

[0091] Other embodiments of this disclosure also provide a drone, including: a drone shell, a first air inlet and a first air outlet communicating with the internal space of the drone shell, the first air inlet being located at the bottom of the drone shell, a first functional component being provided inside the drone shell; a first heat dissipation component for dissipating heat from the first functional component being provided inside the drone shell, the first heat dissipation component being in contact with the first functional component, a heat dissipation duct being formed inside the first heat dissipation component, and a second air inlet and a second air outlet communicating with the heat dissipation duct being provided at the bottom of the drone shell.

[0092] It should be noted that due to the diversity of drones, different types of drones have different structures. Some drones include a drone nose and a drone fuselage, with their heat-generating components located inside the nose housing. For these drones, the drone nose can adopt any of the drone noses described in the above embodiments. The drone housing in this embodiment can include the nose housing of any of the drone noses described in the above embodiments, with the drone's heat-generating components located inside the nose housing. That is, the drone in this embodiment can use the heat dissipation layout of any of the drone noses described in the above embodiments to dissipate heat from the drone nose, achieving good waterproof and dustproof performance and high heat dissipation efficiency.

[0093] Of course, some drones do not have their heat-generating components located inside the drone's nose shell (for example, some drones do not strictly distinguish between the drone's nose and body; they do not have a separate nose shell but instead use an integral drone shell, with the heat-generating components located inside the drone shell). For these drones, the heat dissipation layout can be based on the design concept of the drone's nose in any of the above embodiments, which can also achieve the purpose of good waterproof and dustproof performance and high heat dissipation efficiency.

[0094] Specifically, by providing a first air inlet and a first air outlet on the drone shell that communicate with the internal space of the drone shell, better ventilation is achieved inside the drone shell, thereby dissipating heat from the heat-generating components distributed throughout the drone shell. Furthermore, by incorporating a first heat dissipation component inside the drone shell for dissipating heat from the main heat-generating components, and by forming a heat dissipation duct inside the first heat dissipation component that communicates with the first air inlet and the second air outlet located at the bottom of the drone shell, heat dissipation is achieved from the main heat-generating components inside the drone shell, thus solving the problem of heat generation within the drone shell. This design addresses the heating issues of components and heat-generating elements distributed throughout the drone's casing. This heat dissipation layout effectively isolates heat-generating components within the drone's casing, improving the convective heat transfer coefficient of most of these components and thus achieving higher heat dissipation efficiency. Simultaneously, the first air inlet, second air inlet, and second air outlet are all located at the bottom of the drone's casing, effectively enhancing waterproofing and dustproofing. This satisfies both waterproofing and dustproofing requirements, as well as the heat dissipation needs of the more powerful and heat-consuming drone's nose section. This heat dissipation layout is more applicable to drones of various layouts and sizes, offers better waterproofing and dustproofing, and boasts higher heat dissipation efficiency.

[0095] It should be noted that the specific structure of the first heat dissipation component installed inside the drone shell can be the same as the first heat dissipation component in the drone head of any of the above embodiments, or can be adapted accordingly; the specific structures of the first air inlet, first air outlet, second air inlet, second air outlet, etc. installed on the drone shell can be the same as the corresponding structures on the head shell of any of the above embodiments, or can be adapted accordingly, and will not be described in detail here.

[0096] In some embodiments, the drone housing includes a second functional component and a second heat dissipation component for dissipating heat from the second functional component, the second heat dissipation component being fitted into the second functional component. The specific structure of the second heat dissipation component can be the same as that of the second heat dissipation component on the drone nose of any of the above embodiments, or can be adapted accordingly, and will not be described in detail here.

[0097] In some embodiments, the drone also includes a drone main support set inside the drone housing, a binocular structural frame installed at the front end of the drone main support, a guide plate support fixedly connected to the drone main support, and a guide plate fixedly connected to the guide plate support. These structures can all adopt the same structure as the corresponding component in the drone head of any of the above embodiments or be adapted accordingly, and will not be described in detail here.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
