[0073] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0074] An embodiment of the present application provides a drone hangar 100 suitable for installation on a vehicle. The drone hangar 100 can be installed on a luggage rack on the top of the vehicle, or the drone hangar 100 can be embedded on the top of the vehicle.

[0075] like Figure 1 and Figure 2 The drone hangar 100 includes a cabin 3, a drone (not shown), a door assembly 10, and a door opening and closing mechanism.

[0076] The cabin 3 is provided with an exit 31 , through which the UAV is lifted to the outside of the cabin 3 , or the UAV is accommodated in the cabin 3 through the exit 31 .

[0077] The door assembly 10 is movably connected to the cabin 3, and is suitable for opening or closing the exit 31 of the cabin 3. In one embodiment, the door assembly 10 includes a first door 11 and a second door 12, the first door 11 corresponds to the left side of the vehicle, and the second door 12 corresponds to the right side of the vehicle, and the first door 11 and the second door 12 jointly close the exit 31, or the first door 11 and the second door 12 jointly open the exit 31.

[0078] The hatch door opening and closing mechanism includes a first hatch door opening and closing mechanism 41 and a second hatch door opening and closing mechanism 42. The first hatch door opening and closing mechanism 41 is movably connected to the first hatch 11 and is used to drive the first hatch 11 to move to open or close the exit 31. The second hatch door opening and closing mechanism 42 is movably connected to the second hatch 12 and is used to drive the second hatch 12 to move to open or close the exit 31. By using different hatch door opening and closing mechanisms 42 to independently control the opening and closing of the first hatch 11 and the second hatch 12, the hatch structure is opened and closed in steps.

[0079] In a specific implementation, Figure 3 As shown, the first hatch opening and closing mechanism 41 is configured as a linkage mechanism, and the first hatch opening and closing mechanism 41 includes two first hatch connecting rod assemblies 43, and the two first hatch connecting rod assemblies 43 are respectively connected to the two sides of the first hatch 11, and the two first hatch connecting rod assemblies 43 are used to drive the first hatch 11 to rotate along a suitable track to open or close the exit 31. Compared with a single connecting rod assembly, two connecting rod assemblies are used to drive the first hatch 11 to rotate, so that the opening and closing processes of the first hatch 11 are more stable and prevented from flipping.

[0080] The two first door link assemblies 43 are configured to be driven by the same driving member 5, so as to improve the transmission efficiency while keeping the two first door link assemblies 43 rotating synchronously. The driving member 5 may be a motor.

[0081] In a specific embodiment, Figure 4As shown, the second hatch door opening and closing mechanism 42 is configured as a linkage mechanism, and the second hatch door opening and closing mechanism 42 includes two second hatch door linkage assemblies 44, and the two second hatch door linkage assemblies 44 are respectively connected to the two sides of the second hatch door 12, and the two second hatch door linkage assemblies 44 are used to drive the second hatch door 12 to rotate along a suitable track to open or close the exit 31. Compared with a single linkage assembly, two linkage assemblies are used to drive the second hatch door 12 to rotate, so that the opening and closing processes of the second hatch door 12 are more stable and prevented from flipping.

[0082] The two second door link assemblies 44 are configured to be driven by the same driving member 5, so as to improve the transmission efficiency while keeping the two second door link assemblies 44 rotating synchronously. The driving member 5 may be a motor.

[0083] refer to Figure 7 and Figure 8 In some embodiments, the first door link assembly 43 and the second door link assembly 44 each include a first link 45 , a second link 46 and a third link 47 .

[0084] One end of the first connecting rod 45 is suitable for driving the first door 11 or the second door 12 to move through the first hinge point A, and the other end of the first connecting rod 45 is rotatably connected to the base 48 of the cabin 3 through the second hinge point F. The first connecting rod 45 can be directly connected to the first door 11 or the second door 12, and can also be connected to the first door mounting seat or the second door mounting seat.

[0085] One end of the second connecting rod 46 is rotatably connected to the first connecting rod 45 via the third hinge point C, and the other end of the second connecting rod 46 is used for transmission connection with the driving member 5.

[0086] One end of the third connecting rod 47 is suitable for driving the first door 11 or the second door 12 to move through the fourth hinge point B, and the other end of the third connecting rod 47 is rotatably connected to the base 48 of the cabin 3 through the fifth hinge point G. Among them, the third connecting rod 47 can be directly connected to the first door 11 or the second door 12, and can also be connected to the first door mounting seat or the second door mounting seat.

[0087] Among them, one end of the first connecting rod 45 and one end of the third connecting rod 47 are respectively connected to different positions of the first hatch 11 or the second hatch 12. In a specific implementation, one end of the first connecting rod 45 is connected to one end of the first hatch 11 or the second hatch 12, and one end of the third connecting rod 47 is connected to the middle position of the first hatch 11 or the second hatch 12.

[0088] Define a first virtual connection line AF, which is set as a virtual line segment connecting the first hinge point A and the second hinge point F. The midpoint of the first virtual connection line AF is M, and the positive projection of the third hinge point C on the first virtual connection line AF is located between the midpoint M of the first virtual connection line AF and the second hinge point F.

[0089] It should be noted that the orthographic projection of the third hinge point C on the first virtual connection line AF is located between the midpoint M of the first virtual connection line AF and the second hinge point F, and includes two situations: the first is that the third hinge point C is located on the first virtual connection line AF, and the third hinge point C is located between the midpoint M and the second hinge point F; the second is that the third hinge point C is not located on the first virtual connection line AF, and the orthographic projection of the third hinge point C on the first virtual connection line AF is located between the midpoint M and the second hinge point F.

[0090] By placing the positive projection of the third hinge point C on the first virtual connecting line AF between the midpoint M of the first virtual connecting line AF and the second hinge point F, when the second connecting rod 46 is set to be driven preferentially, the second connecting rod 46 successively drives the first connecting rod 45, the first hatch 11 or the second hatch 12 and the third connecting rod 47 to move. At this time, the transmission efficiency of the hatch assembly 10 can be significantly improved, thereby improving the efficiency of the hatch opening and closing process.

[0091] In some embodiments, continue to refer to Figure 7 and Figure 8 , define a second virtual connection line CF, the second virtual connection line CF is set to connect the third hinge point C and the second hinge point F, and the ratio of the length of the second virtual connection line CF to the length of the first virtual connection line AF is not less than 0.285.

[0092] The applicant studied and analyzed the position of the third hinge point C and found that the smaller the ratio of the length of the second virtual connection line CF to the length of the first virtual connection line AF, the larger the maximum opening of the hatch. However, the hatch can only be opened normally when the ratio of the length of the second virtual connection line CF to the length of the first virtual connection line AF is not less than 0.285.

[0093] In some specific embodiments, when the ratio of the length of the second virtual connection line CF to the length of the first virtual connection line AF is 0.29 to 0.35 (including the endpoint values), it is beneficial for the hatch door to maintain a large opening and facilitate the normal opening of the hatch door. The hatch door opening refers to the degree of opening of the hatch door. In the embodiments of the present application, the hatch door opening is defined by the size of the value.

[0094] In a specific embodiment, the ratio of the length of the second dummy connection line CF to the length of the first dummy connection line AF is 0.3.

[0095] Continue to refer Figure 8 As shown in the figure, when the ratio of the length of the second virtual connection line CF to the length of the first virtual connection line AF is 0.286, the maximum opening of the hatch is 384 mm. When the ratio of the length of the second virtual connection line CF to the length of the first virtual connection line AF is 0.3, the maximum opening of the hatch is 358.5 mm. When the ratio of the length of the second virtual connection line CF to the length of the first virtual connection line AF is 0.35, the maximum opening of the hatch is 314.5 mm.

[0096] In some embodiments, Figure 5 and Figure 6 As shown, the opening process of the exit 31 of the cabin 3 is set as follows: the first door opening and closing mechanism 41 first drives the first door 11 to rotate to open a part of the exit 31, and then the second door opening and closing mechanism 42 drives the second door 12 to rotate and open the other part of the exit 31. By setting the first door 11 and the second door 12 to open successively, the opening degree of the exit 31 can be increased while preventing the two first doors 11 and the second door 12 from interfering with each other during the opening process.

[0097] In some embodiments, the closing process of the exit 31 of the cabin 3 is configured such that the second door opening and closing mechanism 42 first drives the second door 12 to rotate so as to close a portion of the exit 31, and then the first door opening and closing mechanism 41 drives the first door 11 to rotate and close the other portion of the exit 31. By setting the second door 12 and the first door 11 to close successively, interference between the first door 11 and the second door 12 is prevented during the closing process.

[0098] In one embodiment, continue to refer to Figure 5 and Figure 6 As shown, the opening motion trajectory of the first door 11 is set to be first away from the cabin 3 and then close to the cabin 3 in the direction from the inside of the cabin 3 to the outside of the cabin 3, that is, the first door 11 first rises and then falls. The motion trajectory of the first door 11 is as shown in FIG. Figure 5 and Figure 6 As shown by the dotted line. By configuring the first hatch 11 to rise first and then fall, the first hatch 11 is switched from the closed state to the open state, and the center of gravity of the first hatch 11 remains basically unchanged, which is conducive to preventing the first hatch 11 from flipping over. Correspondingly, the closing motion trajectory of the first hatch 11 is set to first move away from the cabin 3 and then approach the cabin 3, that is, the first hatch 11 rises first and then falls. By configuring the first hatch 11 to rise first and then fall, the first hatch 11 is switched from the open state to the closed state, and the center of gravity of the first hatch 11 remains basically unchanged, which is conducive to preventing the first hatch 11 from flipping over.

[0099] In one embodiment, the opening motion trajectory of the second door 12 is configured to be first away from the cabin 3 and then close to the cabin 3 in the direction from the inside of the cabin 3 to the outside of the cabin 3, that is, the second door 12 first rises and then falls. By configuring the second door 12 to first rise and then fall, the motion trajectory of the second door 12 is as follows: Figure 5 and Figure 6 As shown by the dotted line, the second door 12 is switched from the closed state to the open state, and the center of gravity of the second door 12 remains substantially unchanged, which is conducive to preventing the second door 12 from turning over. Correspondingly, the closing motion trajectory of the second door 12 is set to first move away from the cabin 3 and then approach the cabin 3, that is, the second door 12 first rises and then falls. By configuring the second door 12 to first rise and then fall, the second door 12 is switched from the open state to the closed state, and the center of gravity of the second door 12 remains substantially unchanged, which is conducive to preventing the second door 12 from turning over.

[0100] In some embodiments, Fig. 9 As shown, the door assembly 10 further includes a first door seal 21 and a second door first seal 22, wherein the first door seal 21 is installed on the first door 11, and the second door first seal 22 is installed on the second door 12. The second door first seal 22 is provided with a notch 223, and when the exit 31 of the cabin 3 is closed, the first door seal 21 abuts against the second door 12 through the notch 223.

[0101] It can be understood that during the opening of the first hatch 11, the first hatch seal 21 moves with the first hatch 11, and the second hatch first seal 22 moves with the second hatch 12. In order to improve the sealing performance, the first hatch seal 21 and the second hatch first seal 22 are compressed and assembled between the first hatch 11 and the second hatch 12. By providing a notch 223 at the position of the second hatch first seal 22 corresponding to the position where the first hatch seal 21 abuts against the second hatch 12, when the first hatch seal 21 moves with the first hatch 11, there is no interference between the first hatch seal 21 and the second hatch first seal 22, thereby effectively preventing the first hatch seal 21 from loosening during the opening of the first hatch 11.

[0102] In some embodiments, continue to refer to Figures 9 to 15The first door seal 21 includes a first door abutting portion 211 and a first door mounting portion 212 which are connected to each other, wherein the first door abutting portion 211 includes a side wall and an end wall, the side wall of the first door abutting portion 211 abuts against the first cabin abutting surface 33 of the cabin shell 32 of the cabin 3, and the end wall of the first door abutting portion 211 abuts against the second door 12 through the notch 223, so that when the first door 11 is in a closed state, the connection between the first door 11 and the cabin shell 32 of the cabin 3 forms a sealed connection, and the connection between the first door 11 and the second door 12 forms a sealed connection, thereby improving the overall sealing performance of the unmanned aerial vehicle hangar 100.

[0103] The first door mounting portion 212 is mounted on the first door 11 , so that when the first door 11 is opened, the first door sealing member 21 moves with the first door 11 , thereby not occupying the exit 31 of the cabin 3 and increasing the opening of the exit 31 .

[0104] In a specific implementation, the first door installation portion 212 is installed on the outer peripheral side of the first door 11 , so as to facilitate the disassembly and assembly of the first door seal 21 .

[0105] In some embodiments, Fig. 9 , Fig.12 and Fig.13 As shown, a first card slot 13 is provided on the outer side surface of the first door 11, and the first door mounting portion 212 includes a circle of protruding structures arranged on the inner side surface of the first door abutting portion 211. The first door mounting portion 212 is snapped into the first card slot 13, thereby facilitating the rapid disassembly and assembly of the first door seal 21 on the first door 11.

[0106] In some embodiments, Fig.12 As shown, the second door 12 includes a second door abutting surface 121, an end wall of the first door abutting portion 211 abuts against the second door abutting surface 121, and a first door mounting portion 212 located on the inner side of the end of the first door abutting portion 211 is clamped into the first clamping groove 13 of the first door 11. The first door mounting portion 212 is configured to be clamped into the first clamping groove 13 after being compressed so that the first door seal 21 is stably fixed on the first door 11. Wherein, at the point where the first door 11 abuts against the second door 12, there is a first angle between the clamping force direction of the first door seal 21 and the second door abutting surface 121, and the clamping force direction of the first door seal 21 is as shown in FIG. Fig.12 As shown in F1, the extension direction of the second hatch door abutting surface 121 is the direction of the friction force on the first hatch door sealing member 21. Fig.12 As shown in F2, the movement direction of the first hatch 11 during the opening process is as follows Fig.12 F3 shown.

[0107] It is understandable that the extension direction of the second door abutting surface 121 is set to be the direction of the friction force on the first door seal 21 when the first door seal 21 is separated from the second door abutting surface 121. By setting the direction of the clamping force between the first door seal 21 and the first door 11 to have a first angle with the second door abutting surface 121, when the first door seal 21 follows the first door 11 to open the outlet 31, the first door 11 and the first door seal 21 are set to rotate obliquely upward. Since the direction F2 of the friction force on the first door seal 21 is different from the direction F1 of the clamping force on the first door seal 21 when it is clamped in the first clamping groove 13, the first door seal 21 will not be directly dropped due to the friction force.

[0108] In a specific implementation, the first door seal 21 abuts against the second door abutting surface 121, the first door seal 21 is clamped in the first clamping groove 13 of the first door 11 along the first direction, and the second door abutting surface 121 is set at an angle with the first direction, such as Fig.12 As shown, the first direction is F1, and the extending direction of the second hatch door abutting surface 121 is F2. This is helpful to prevent the first hatch door seal 21 from falling off due to excessive friction between the first hatch door seal 21 and the second hatch door 12 when the first hatch door seal 21 is separated from the second hatch door abutting surface 121.

[0109] In a specific implementation, the first angle between the second door abutment surface 121 and the first direction is a right angle, which helps prevent the first door seal 21 from falling off due to excessive friction between the first door seal 21 and the second door abutment surface 121 when the first door seal 21 is separated from the second door 12.

[0110] In some embodiments, Fig.13 As shown, the side wall of the first door abutting portion 211 abuts against the first cabin abutting surface 33, and the first door mounting portion 212 on the inner side of the side wall of the first door abutting portion 211 is mounted in the first slot 13 of the first door 11. Correspondingly, the first door mounting portion 212 is configured to be clamped in the first slot 13 after being compressed so that the first door seal 21 is stably fixed on the first door 11. Where the first door seal 21 abuts against the cabin abutting surface 33, the first door seal 21 is clamped in the slot 13 of the first door 11 along the second direction, wherein the second direction is as shown in FIG. Fig.13 As shown in F1, the extension direction of the cabin abutment surface 33 is as follows Fig.13 As shown in F2, the second direction has a second included angle with the first cabin abutting surface 33. It is understandable that the extension direction of the first cabin abutting surface 33 is set to be the direction of the friction force exerted on the first cabin door seal 21 when the first cabin door seal 21 is separated from the first cabin abutting surface 33. The friction force direction is as follows: Fig.13 The F2 shown in FIG. 2 sets the direction of the clamping force between the first door seal 21 and the first door 11 to have a second angle between the first cabin abutment surface 33, so that when the first door seal 21 follows the first door 11 to open or close the exit 31 of the cabin 3, the first door seal 21 will not fall off directly due to the friction force.

[0111] In a specific implementation, the angle between the first cabin abutment surface 33 and the second direction is a right angle, which is helpful in preventing the first cabin door seal 21 from falling off due to excessive friction between the first cabin abutment surface 33 when the first cabin door seal 21 is separated from the first cabin abutment surface 33.

[0112] In a specific implementation, Fig. 9 As shown, the first door seal 21 is D-shaped, so that the first door seal 21 can stably fit the first door 11, the cabin 3 and the second door 12 to improve the sealing performance of the drone hangar 100.

[0113] In some embodiments, Fig.16 As shown, the first door seal 21 has a first hollow structure 214 and a second hollow structure 225, so that the first door seal 21 has a compressible property, so that the first door seal 21 can effectively seal the connection gap between the first door 11 and the cabin shell and the connection gap between the first door 11 and the second door 12. When the first door seal 21 is installed on the first door 11, the first hollow structure 214 is squeezed and deformed, and the second hollow structure 225 is deformed when it abuts against the cabin shell or the second door 12.

[0114] The first seal 22 of the second door also has a first hollow structure 214 and a second hollow structure 225, so that the first seal 22 of the second door has a compressive property, so that the first seal 22 of the second door can effectively seal the connection gap between the second door 12 and the cabin shell. When the first seal 22 of the second door is installed on the second door 12, the first hollow structure 214 is squeezed and deformed, and the second hollow structure 225 is deformed when it abuts against the cabin shell.

[0115] In some embodiments, the second hollow structure 225 includes a corner portion 213, and the first corner portion 213 limits the deformation shape of the second hollow structure 225 in the abutting state, so that the first door seal 21 can stably abut against the cabin shell and the second door 12, and the second door first seal 22 can be stably fixed on the cabin shell. The corner portion 213 configures the first door seal 21 and the second door first seal 22 into a step shape, so that the first door seal 21 and the second door first seal 22 form a multi-layer structure reinforcement, and limits the deformation shape of the second hollow structure 225.

[0116] In some embodiments, Fig. 9 , Fig.14 and Fig.15 As shown, the first sealing member 22 of the second door includes a second door abutting portion 221 and a second door mounting portion 222 which are connected to each other, wherein the second door abutting portion 221 abuts against a second cabin abutting surface 34 of a cabin shell 32 of the cabin 3, thereby improving the sealing performance between the second door 12 and the cabin shell 32 of the cabin 3.

[0117] The second door first seal 22 is installed on the second door 12 through the second door installation portion 222, so that when the second door 12 is opened or closed, the second door first seal 22 moves with the second door 12, which is beneficial to increase the opening of the outlet 31 of the cabin 3.

[0118] In a specific implementation, the second door mounting portion 222 is mounted on the outer peripheral side of the second door 12, so as to facilitate quick disassembly and assembly of the second door first sealing member 22.

[0119] In some embodiments, the second door mounting portion 222 is detachably mounted on the second door 12, thereby facilitating the disassembly and assembly between the second door first sealing member 22 and the second door 12. In a specific implementation, the detachable connection between the second door mounting portion 222 and the second door 12 includes snap-fitting or plug-fitting.

[0120] In a specific implementation, Fig. 9 and Fig.14 As shown, a second card groove 14 is provided on the outer side surface of the second door 12, and the second door mounting portion 222 includes a circle of ridges arranged on the inner side of the second door abutting portion 221. The second door mounting portion 222 is snapped into the second card groove 14, thereby facilitating a stable connection between the second door first sealing member 22 and the second door 12, while improving the sealing performance.

[0121] When the exit 31 of the cabin 3 is closed, the second door 12 abuts against the cabin shell, the second door abutting portion 221 abuts against the second cabin abutting surface 34, and the second door mounting portion 222 on the inner side wall of the second door abutting portion 221 is clamped into the second clamping groove 14 of the second door 12 along the third direction. The third direction is as follows: Fig.14 In the F1 direction shown, the extension direction of the second cabin abutment surface 34 is as follows: Fig.14 In the F2 direction, the second door mounting portion 222 is correspondingly configured to be clamped in the second clamping groove 14 after being compressed so that the second door first seal 22 is stably fixed on the second door 12. There is a third angle between the clamping force direction of the second door first seal 22 and the second cabin abutting surface 34. It is understandable that the extension direction of the second cabin abutting surface 34 is set to be the direction of the friction force on the second door first seal 22 when the second door first seal 22 is separated from the second cabin abutting surface 34, as shown in FIG. Fig.12 As shown in F2, by setting the direction of the clamping force between the first seal 22 of the second door and the second door 12 to have a third angle with the second cabin abutment surface 34, when the first seal 22 of the second door follows the second door 12 to open or close the exit 31 of the cabin 3, the first seal 22 of the second door will not fall off directly due to the friction force.

[0122] In a specific implementation, the angle between the second cabin abutment surface 34 and the direction of the clamping force of the first seal 22 of the second cabin door is a right angle, which is helpful in preventing the first seal 22 of the second cabin door from falling off due to excessive friction between the first seal 22 of the second cabin door and the second cabin abutment surface 34 when the first seal 22 of the second cabin door is separated from the second cabin abutment surface 34.

[0123] In a specific implementation, the first seal 22 of the second door is C-shaped, which is conducive to the sealing fit between the first seal 22 of the second door and the second door 12 and the cabin shell 32 of the cabin 3, so as to improve the sealing performance.

[0124] In some embodiments, Fig.12 As shown, the door assembly 10 further includes a second door second seal 23 installed on the second door 12, and the second door second seal 23 is installed at the end of the second door 12 and close to the connection between the first door 11 and the second door 12. The installation direction of the second door second seal 23 intersects with the installation direction of the first door seal 21, so that the first door 11 and the second door 12 form a sealing structure at different positions and in different directions, thereby effectively improving the sealing performance of the drone hangar 100.

[0125] In a specific implementation, the first door seal 21 is installed on the first door 11 in a direction perpendicular to the outer side surface of the first door 11, and the second door second seal 23 is installed on the second door 12 in a direction perpendicular to the plane where the first door 11 is located or the plane where the second door 12 is located. When the exit 31 of the cabin 3 is in a closed state, the second door second seal 23 is compressed and longitudinally abuts against the inner wall surface of the first door 11. The second door second seal 23 is configured as a strip.

[0126] In some embodiments, Fig.13 , Fig.14 As shown, the nacelle 3 includes a nacelle shell 32, and the nacelle shell 32 is provided with a shell seal 35, and the shell seal 35 is set as a circumferentially closed sealing ring structure, and the shell seal 35 abuts against the first door 11 and the second door 12. In a specific implementation, the first door 11 and the second door 12 both include a door inner plate and a door outer plate connected to each other, and the first door seal 21 is installed on the door outer plate, so as to facilitate the improvement of the upper sealing structure of the connection between the first door 11 and the nacelle shell 32 of the nacelle 3 and the second door 12, and the shell seal 35 abuts against the door inner plates of the first door 11 and the second door 12, so as to facilitate the improvement of the lower sealing structure of the connection between the first door 11 and the nacelle 3 and the connection between the second door 12 and the nacelle 3, thereby improving the overall sealing performance of the door assembly 10 installed on the nacelle 3.
