Detailed Implementation

[0045] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0046] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0047] The following is combined Figures 1-10 The present application describes in detail a ventilation grille 2, a drone hangar 10 having the ventilation grille 2, and a vehicle 100 having the drone hangar 10.

[0048] Reference Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, the ventilation grille 2 according to an embodiment of this application is applied to the drone hangar 10. The ventilation grille 2 includes grille holes and mounting parts 3. The grille holes are adapted to connect the drone housing cavity inside the drone hangar 10 with the external environment. The ventilation grille 2 is adapted to be detachably installed in the drone hangar 10 via the mounting parts 3.

[0049] Specifically, the drones inside the drone housing generate heat during operation or charging. The grille openings connect the drone housing to the external environment, forming a ventilation channel. Hot air can naturally escape from the drone housing 10 through the grille openings and be discharged into the external environment. At the same time, cold air from the outside will enter the drone housing 10 through the grille openings, effectively removing the heat from the drone housing. This prevents the drones inside the housing from overheating, experiencing performance degradation, or even being damaged due to prolonged charging or battery heat dissipation, thus reducing energy consumption and equipment costs.

[0050] The ventilation grille 2 is suitable for detachable installation on the drone hangar 10 via the mounting part 3, so that the ventilation grille 2 can be removed and cleaned at any time. The ventilation grille 2 will not suffer from reduced ventilation and heat dissipation performance due to dirt and blockage of the parts (such as dustproof net 212) or grille holes due to long-term use. Moreover, the ventilation grille 2 can be designed and replaced according to actual needs (such as different shapes of grille bars 221) without being affected by the design requirements of the drone hangar 10 shell mold, thus improving the practicality and applicability of the ventilation grille 2.

[0051] In related technologies, ventilation grilles on drone hangars are usually equipped with ventilation holes. However, long-term use of ventilation grilles can easily cause dust and foreign objects to clog the ventilation holes, resulting in a decrease in the ventilation and heat dissipation performance of the drone hangar.

[0052] According to the embodiment of this application, the ventilation grille 2 is detachably installed on the drone hangar 10 by the mounting part 3, so that the ventilation grille 2 can be removed and cleaned or replaced at any time, thereby avoiding the problem of reduced ventilation and heat dissipation performance caused by long-term accumulation of dirt (such as dust, foreign objects, etc.), and improving the durability and heat dissipation of the ventilation grille 2.

[0053] In some embodiments of this application, see Figure 1 , Figure 2 , Figure 5 , Figure 6 As shown, the ventilation grille 2 includes a mounting frame 21 and a grille body 22. The mounting frame 21 is adapted to be detachably installed on the unmanned aerial vehicle hangar 10 via the mounting part 3. The grille body 22 is installed on the mounting frame 21, and grille holes are provided on the grille body 22. Specifically, the ventilation grille 2 adopts a combined structure of the mounting frame 21 and the grille body 22, and the mounting frame 21 is adapted to be detachably installed on the unmanned aerial vehicle hangar 10 via the mounting part 3. Specifically, the mounting frame 21 is adapted to be detachably installed on the hangar shell 1 of the unmanned aerial vehicle hangar 10 via the mounting part 3, making the entire ventilation grille 2 easy to maintain and replace. When the ventilation grille 2 has a problem (for example, the mounting frame 21 is deformed or damaged due to long-term use, or the grille body 22 is blocked or broken by foreign objects), it is only necessary to remove the mounting frame 21 from the hangar shell 1 and replace it with a new ventilation grille 2, without the need for complex disassembly and reassembly of the entire hangar shell 1.

[0054] In some embodiments, the grille body 22 is detachably mounted on the mounting frame 21. If there is a problem with the grille body 22, it can be easily removed from the mounting frame 21 for cleaning, repair or replacement. The operation is relatively simple, reducing maintenance costs and time costs.

[0055] In other embodiments, the grille body 22 is fixedly installed on the mounting frame 21. If there is a problem with the grille body 22, the mounting frame 21 is removed from the hangar shell 1 and a new ventilation grille 2 is replaced.

[0056] In some embodiments of this application, see Figures 1-3 , Figure 9 As shown, an installation cavity 23 is formed between the mounting frame 21 and the grille body 22. The grille body 22 includes grille bars 221, and each grille bar 221 includes a water guide section 2211. The water guide section 2211 is inclined relative to the horizontal plane, and the end of the water guide section 2211 away from the installation cavity 23 (i.e., Figure 2 The left end of the middle section is lower than the end of the water guide section 2211 near the mounting cavity 23 (i.e., Figure 2 (Right end). Specifically, the water guide section 2211 is inclined relative to the horizontal plane, and Figure 2 In the middle, the left end of the water guide section 2211 is lower than the right end, which can guide rainwater to flow outward along the water guide section 2211, preventing rainwater from accumulating on the grid body 22 and flowing into the mounting cavity 23 through the grid holes. This also prevents rainwater from entering the drone housing cavity through the mounting cavity 23, which plays a good waterproof role and protects the drone from rainwater corrosion.

[0057] It is important to understand that the horizontal plane is a completely horizontal plane, perpendicular to the direction of Earth's gravity. Furthermore, the horizontal plane is not part of the structure of the unmanned aerial vehicle hangar 10 in this application; it is only used to aid in understanding the geometric relationships between the various components of the unmanned aerial vehicle hangar 10.

[0058] In some embodiments of this application, see Figures 1-3 As shown, the inclination angle of the water guide section 2211 relative to the horizontal plane is not less than 3°. Specifically, setting the inclination angle of the water guide section 2211 relative to the horizontal plane to not less than 3° is sufficient to form a significant drainage slope, allowing liquid to flow smoothly along the water guide section 2211. This effectively prevents water accumulation on the grid strips 221 and ensures that rainwater or other liquids can quickly flow out from the grid body 22 under the action of gravity, thereby preventing liquid backflow into the installation cavity 23 and, consequently, preventing liquid backflow into the UAV's receiving cavity.

[0059] Optionally, the angle of inclination of the water guide section 2211 relative to the horizontal plane can be 3°, 4°, 5° or other degrees not less than 3°.

[0060] In some embodiments of this application, see Figure 2 , Figure 6As shown, the grating strip 221 also includes a first extension section 2212, the upper end of which is connected to the lower end of the water guide section 2211. The first extension section 2212 is folded towards the mounting cavity 23 relative to the water guide section 2211. Specifically, when there is heavy rain or the drainage speed is fast, water flowing directly from the water guide section 2211 may cause splashing. The folding of the first extension section 2212 allows the water to slide along its surface, reducing the impact force of the water. This effectively prevents water from splashing back to the grating body 22 or the vicinity of the mounting cavity 23, helping to maintain a dry environment around the mounting cavity 23 and the UAV housing cavity, further reducing various potential risks caused by water, such as equipment dampness and corrosion.

[0061] In some embodiments of this application, see Figure 2 , Figure 6 As shown, the grille strip 221 also includes a second extension 2213, the lower end of which is connected to the upper end of the water guide section 2211. The second extension 2213 is folded away from the mounting cavity 23 relative to the water guide section 2211. Specifically, when rainwater falls from a height or flows rapidly in the water guide section 2211, splashing may occur. The folded structure of the second extension 2213 can prevent rainwater splashed onto the water guide section 2211 from entering the mounting cavity 23. By changing the splashing direction of the rainwater, the rainwater is guided to the outside of the drone hangar 10, better protecting the dry environment inside the mounting cavity 23, and thus better protecting the dry environment inside the drone housing cavity, reducing the possibility of damage to the drone due to moisture.

[0062] In some embodiments of this application, see Figure 2 , Figure 6 As shown, both the first extension segment 2212 and the second extension segment 2213 are flat plates, and the angle between them ranges from ±10°. Specifically, the flatness of both extension segments 2212 and 2213 facilitates water flow guidance. The ±10° angle between the two extension segments ensures they are parallel or nearly parallel, creating a relatively stable and smooth channel for airflow. When air enters through the grille openings, the parallel or nearly parallel angle between the two segments allows for more uniform and stable airflow along the extension segments 2212 and 2213, reducing turbulence and vortex phenomena, improving ventilation efficiency, and facilitating the more effective removal of hot air from the UAV's housing while simultaneously introducing fresh outside air, maintaining a suitable temperature environment within the UAV's housing.

[0063] Optionally, the angle between the first extension segment 2212 and the second extension segment 2213 can be -10°, -5°, 0°, +5°, +10°, or other values ​​between -10° and +10°. It is understood that, with the first extension segment 2212 as a reference, when the first extension segment 2212 and the second extension segment 2213 are parallel, the angle between them is 0°. With the first extension segment 2212 as a reference, when the second extension segment 2213 deflects clockwise relative to the first extension segment 2212, the angle between them is a positive angle. With the first extension segment 2212 as a reference, when the second extension segment 2213 deflects counterclockwise relative to the first extension segment 2212, the angle between them is a negative angle.

[0064] In some embodiments of this application, see Figure 1 , Figure 2 , Figure 7 , Figure 8 As shown, the grille body 22 includes a grille frame 222 and multiple grille bars 221, the grille bars 221 being arranged along a first direction (e.g., Figure 1 The multiple grille bars 221 extend in the vertical direction and connect to the grille frame 222, and in the second direction (e.g., vertical direction) they connect to the grille frame 222. Figure 1 The grille bars 221 are spaced apart in the left-right direction, with grille holes formed on both sides of the grille bars 221 in the second direction, which are different directions from the first direction. Specifically, the grille bars 221 extend along the first direction and are spaced apart in the second direction, so that the grille holes are distributed in two different directions, greatly increasing the effective ventilation area. In the drone hangar 10, air can be exchanged through these grille holes at different angles and positions, which is conducive to the rapid exhaust of hot air in the drone's housing cavity, while allowing fresh air from the outside to enter more smoothly, thereby improving ventilation efficiency and ensuring that the drone can be in a good temperature environment during operation or storage.

[0065] In some embodiments of this application, see Figure 1 , Figure 2 , Figure 7 , Figure 8 As shown, the first direction is perpendicular to the second direction. Specifically, when the first direction is perpendicular to the second direction, the grille bars 221 are arranged along two mutually perpendicular directions, which makes the distribution of grille holes on the plane more regular and uniform. Air can smoothly enter and exit the mounting cavity 23 through the uniformly distributed grille holes, greatly increasing the airflow path and exchange efficiency, ensuring that the temperature inside the mounting cavity 23 and the UAV housing cavity can be maintained within a suitable range, effectively avoiding overheating that could affect the performance of the UAV.

[0066] In summary, the grid bar 221 can be a blade-shaped grid (such as...).Figure 9 As shown), Z-shaped grille (such as) Figure 2 (as shown) or other shapes of grilles.

[0067] In some embodiments of this application, see Figure 2 , Figure 4 , Figure 6 As shown, the grille body 22 is provided with a drain outlet 223. An installation cavity 23 is formed between the mounting frame 21 and the grille body 22. The mounting frame 21 includes a base plate 211, which forms the bottom wall of the installation cavity 23. The base plate 211 is inclined relative to the horizontal plane, with the end of the base plate 211 near the drain outlet 223 lower than the end of the base plate 211 away from the drain outlet 223. The base plate 211 extends to the drain outlet 223. Specifically, the inclined arrangement of the base plate 211 relative to the horizontal plane, with the end of the base plate 211 near the drain outlet 223 lower than the end away from the drain outlet 223, allows rainwater, condensate, or other liquids falling into the installation cavity 23 to naturally flow towards the drain outlet 233 using gravity. The drain outlet 223 extending from the base plate 211 to the grille body 22 provides a smooth drainage path for these liquids, ensuring that the water can be drained quickly and effectively from the mounting cavity 23, preventing water from accumulating in the cavity, thereby keeping the mounting cavity 23 and the surrounding environment of the drone housing dry, and preventing damage to the drone and its related components due to moisture, such as rust, short circuits, etc.

[0068] In some embodiments of this application, see Figure 4 As shown, the tilt angle of the base plate 211 relative to the horizontal plane is not less than 3°. Specifically, the tilt angle of not less than 3° can provide sufficient gravitational potential energy for the water, allowing the water to flow quickly on the base plate 211 by gravity. This is sufficient to allow the water to flow smoothly from the drain outlet 223 out of the mounting cavity 23, reducing the potential damage to the drone and related components caused by the water accumulation.

[0069] Optionally, the angle of inclination of the base plate 211 relative to the horizontal plane can be 3°, 4°, 5° or other angles not less than 3°.

[0070] In some embodiments of this application, see Figure 2 , Figures 6-8 As shown, the mounting part 3 is a snap-fit ​​structure. Specifically, the mounting frame 21 is fixedly connected to the outer shell 1 of the drone hangar 10 through the snap-fit ​​structure. The snap-fit ​​structure requires relatively low professional skills from the installers and can be accurately completed without complicated installation experience or professional training, reducing the possibility of installation errors due to unfamiliarity with the operation and further ensuring the smooth progress of the installation.

[0071] In some embodiments, see Figures 6-8 , Figures 6-8As shown, the drone hangar 10 includes a mounting section 3, and the mounting frame 21 and the outer shell 1 of the drone hangar 10 are detachably mounted through the mounting section 3.

[0072] In some embodiments not shown in the figure, the mounting part 3 is a threaded fastener. Specifically, the threaded fastener (such as a bolt, nut, etc.) can provide a large tightening force to firmly fix the mounting frame 21 to the outer shell 1 of the drone hangar 10, ensuring that the ventilation grille 2 will not easily loosen or shift, maintaining its normal function of ventilation, protection, etc., providing a stable environment for the storage of drones, and ensuring the safety of drones.

[0073] In some embodiments of this application, see Figures 6-8 , Figures 6-8 As shown, the mounting frame 21 is equipped with a vent, and a mounting cavity 23 is formed between the mounting frame 21 and the grille body 22, connecting the grille holes and the vent. Specifically, the vent design allows air entering from the external environment through the grille holes to have a direct and continuous path to the UAV housing cavity. Air can smoothly enter the cavity by passing through the grille holes and vents in sequence, reducing airflow obstruction and turbulence, thereby improving ventilation efficiency. After the UAV generates heat, the hot air can also be quickly exhausted to the outside along the vents and grille holes, more effectively maintaining a suitable temperature environment inside the UAV housing cavity, ensuring the normal operation of the UAV, and preventing overheating from affecting its performance and service life.

[0074] In some embodiments of this application, see Figures 6-8 , Figures 6-8 As shown, a dustproof net 212 is installed at the ventilation opening. The dustproof net 212 has mesh holes, and the mounting cavity 23 connects the grille holes and the mesh holes. Specifically, the mesh holes of the dustproof net 212 can play a fine filtering role. The size of its pores can be designed as needed to prevent most tiny dust and other foreign objects from passing through, thereby effectively preventing them from entering the drone's housing cavity and adhering to various parts of the drone, ensuring the normal operation and service life of the drone.

[0075] The dustproof net 212 can be connected to the mounting frame 21 at the ventilation opening by welding (e.g., ultrasonic welding), hot melting, adhesive bonding, bolt connection, etc.

[0076] In some embodiments of this application, see Figures 6-8 , Figures 6-8As shown, the ventilation grille 2 also includes a baffle 24 disposed within the mounting cavity 23. The baffle 24 is located between the ventilation opening and at least a portion of the grille holes, and is at least partially separated from the cavity wall of the mounting cavity 23 to form a ventilation channel between the baffle 24 and the cavity wall. The ventilation channel connects the grille holes and the ventilation opening. Specifically, the baffle 24, located between the ventilation opening and at least a portion of the grille holes, can directly block water flow attempting to enter the drone housing cavity. After being blocked by the baffle 24, the water flows along the baffle 24 onto the base plate 211 and flows out of the drone hangar 10 through the drain outlet 223, preventing water from directly rushing towards the ventilation opening and flowing into the drone housing cavity, greatly reducing the risk of the drone housing cavity being soaked by water.

[0077] In some embodiments of this application, see Figures 6-8 As shown, the bottom surface of the baffle 24 is lower than the lowest point of the vent. Therefore, with the bottom surface of the baffle 24 lower than the lowest point of the vent, the baffle 24 acts like a sturdy dam, effectively blocking water from flowing into the vent through the grille holes. This prevents water from entering the drone's storage cavity, maximizing the dryness of the drone's storage cavity and preventing damage such as short circuits in electronic components and rust caused by water ingress. This improves the safety and stability of drone storage.

[0078] In some embodiments of this application, see Figures 6-8 As shown, the distance between the bottom surface of the baffle 24 and the lowest point of the vent is m, and the vertical distance between the bottom surface of the baffle 24 and the grille body 22 is n, satisfying that m > n. Specifically, m > n ensures that there is sufficient space between the vent and the bottom surface of the baffle 24, and between the bottom surface of the baffle 24 and the grille body 22, to form relatively spacious ventilation channels with similar capacity. Air can smoothly enter from the vent, pass under the baffle 24, and then reach the grille body 22, providing sufficient ventilation path for the drone hangar 10. To ensure the heat dissipation requirements of the drone hangar 10, m and n cannot be too small and must meet the minimum ventilation requirements.

[0079] In some embodiments of this application, see Figures 6-8 , Figures 6-8 As shown, the baffle 24 is installed on the mounting frame 21. Specifically, by installing the baffle 24 on the mounting frame 21, the baffle 24 and the mounting frame 21 form an organic whole structure, which prevents the baffle 24 from shaking, shifting or even being damaged due to independent force, and ensures that the baffle 24 is always in the correct position in the mounting cavity 23, maintaining its stable function of blocking water flow, foreign objects and guiding ventilation.

[0080] In some embodiments of this application, see Figures 6-8 , Figures 6-8As shown, the mounting frame 21 has a first support plate 213, and the baffle 24 is adapted to fit against the first support plate 213. Specifically, the first support plate 213 provides a solid contact surface for the baffle 24, which can effectively bear the weight of the baffle 24 and withstand various forces applied to the baffle 24 from the outside, ensuring that the baffle 24 is always in a stable working state and maintaining the functions of the baffle 24 such as water blocking in the drone hangar 10.

[0081] In some embodiments, the first support plate 213 is provided with a plug-in arm 2131, which extends into the plug-in groove 241 of the baffle 24. Thus, through the cooperation of the plug-in arm 2131 and the plug-in groove 241, the positioning and installation of the first support plate 213 and the baffle 24 are realized, and the baffle 24 is always in a stable working state, maintaining the functions of the baffle 24 such as water blocking in the drone hangar 10.

[0082] In some embodiments, the mounting frame 21 is provided with a first support column 215, and the first support column 215 is provided with a plug-in support arm 2131, which extends into the plug-in groove 241 of the baffle 24.

[0083] Optionally, the connection between the baffle 24 and the first support plate 213 can be welding (e.g., ultrasonic welding), hot melting, adhesive bonding, bolting, etc. For example... Figures 6-8 As shown, the connection between the baffle 24 and the first support plate 213 is ultrasonic welding, and the welding position is located at the insertion arm 2131 and the insertion groove 241.

[0084] In some embodiments of this application, see Figures 6-8 , Figures 6-8 As shown, a mounting cavity 23 is formed between the mounting frame 21 and the grille body 22. The mounting frame 21 has a second support plate 214, which surrounds the mounting cavity 23. The second support plate 214 is adapted to have a sealing structure 4 between itself and the hangar shell 1 of the drone hangar 10. Specifically, the second support plate 214 surrounds the mounting cavity 23 like a ring. In conjunction with the sealing structure 4, it forms a continuous, all-around waterproof seal between the mounting frame 21 and the hangar shell 1. This effectively prevents moisture from entering the mounting cavity 23 through the gap between the mounting frame 21 and the hangar shell 1, thereby protecting the ventilation system and drone housing within the mounting cavity 23 from water damage. This ensures the drone is in a dry environment and avoids equipment damage caused by water ingress, such as short circuits in electronic components or rust on parts.

[0085] Optionally, the sealing structure 4 can be sealing foam, rubber sealing ring, sealant, expanding foam, etc.

[0086] Optionally, the sealing structure 4 is located between the second support plate 214 and the hangar shell 1.

[0087] In some embodiments of this application, see Figures 6-8 , Figures 6-8 As shown, the grille body 22 is fixed to the second support plate 214. Specifically, the second support plate 214 is arranged around the mounting cavity 23 and has a certain structural strength. When the grille body 22 is fixed on the second support plate 214, the second support plate 214 can provide stable support for the grille body 22, and will not easily shake, shift or deform, ensuring that it is always in the correct position and maintaining the normal functioning of ventilation and protection.

[0088] Optionally, the connection between the grid body 22 and the second support plate 214 can be welding (e.g., ultrasonic welding), hot melting, adhesive bonding, bolt connection, etc.

[0089] See Figures 6-8 , Figures 6-8 As shown, the drone hangar 10 according to another embodiment of this application includes a hangar shell 1 and the aforementioned ventilation grille 2. The drone housing cavity is disposed inside the hangar shell 1, and the ventilation grille 2 is adapted to be detachably mounted to the hangar shell 1 via a mounting part 3.

[0090] According to another embodiment of the present application, the ventilation grille 2 of the unmanned aerial vehicle hangar 10 is detachably installed on the hangar shell 1 by the mounting part 3, so that the ventilation grille 2 can be removed and cleaned or replaced at any time, thereby avoiding the problem of reduced ventilation and heat dissipation performance caused by long-term accumulation of dirt (such as dust, foreign objects, etc.), and improving the durability and heat dissipation of the ventilation grille 2.

[0091] See Figures 6-8 Figures 6-8 Figures 6-8 Figures 6-8 Figures 6-8 Figures 6-8 Figures 6-8 Figures 6-8 Figures 6-8 Figures 6-8 Figures 6-8 Figures 6-8 Figures 6-8 Figures 6-8 Figures 6-8 Figures 6-8 Figures 6-8 Figures 6-8 Figures 6- As shown, the vehicle 100 according to another aspect of this application includes the aforementioned drone hangar 10.
