Wherein the two doors can relatively rotate under the action of external force to open or close the accommodating space.

The unmanned aerial vehicle according to the embodiment of the present disclosure will be described in detail below with reference to fig. 1A to 1B. Fig. 1A schematically shows a structural plan view of an unmanned aerial vehicle according to an embodiment of the present disclosure in a state of closing an accommodation space; fig. 1B schematically shows a structural plan view of the unmanned aerial vehicle according to the embodiment of the present disclosure in a state of opening the accommodating space.

As shown in fig. 1A to 1B, the unmanned aerial vehicle 1 of the embodiment of the present disclosure includes a head 10, a body 20, and a tail.

The nose 10 is composed of a cabin door 11 and a cabin door 12, and the cabin door 11 and the cabin door 12 are oppositely arranged along a direction perpendicular to the length of the unmanned aerial vehicle (perpendicular to a connecting line between the fuselage and the tail). For example, the door 11 and the door 12 may be arranged opposite to each other in the width direction of the drone or in the height direction of the drone. The hatch 11 and the hatch 12 may be connected by a connection structure such as a snap-fit structure, which is easy to assemble and disassemble, so as to lock or unlock the hatch 11 and the hatch 12.

The fuselage 20 may include an accommodating space 21 surrounded by sidewalls of the fuselage for accommodating cargo. The accommodating space 21 is an open space with respect to the head, i.e., the accommodating space 21 communicates with the head 10. The body 20 and the head 10 may be connected by a snap structure, for example, and the hatch 11 and the hatch 12 constituting the head 10 may be fixedly provided with a rotating shaft on a connecting surface connected with the body 20, for example. In particular, a rotating shaft may be provided in a region away from the door 12/door 11 on the side where the door 11/door 12 abuts the fuselage 20, so as to rotate the door 11 and the door 12 in opposite directions.

When the two doors (the door 11 and the door 12) are unlocked from each other, the two doors may be rotated in opposite directions by an external force to open the accommodating space 21, thereby facilitating loading of cargo into the accommodating space 21 or unloading of cargo from the accommodating space 21. After the cargo is loaded and before the cargo is transported, or before the unmanned aerial vehicle performs other flight tasks, the two cabin doors can be rotated under the action of external force to enable the two cabin doors to be attached to each other and locked with each other so as to close the accommodating space 21.

The maximum angle of relative rotation of the two doors may be 180 °, for example, that is, the maximum angle of rotation of the doors 11 and 12 relative to the fuselage 20 may be 180 °.

In summary, since the two doors constituting the machine head can rotate relatively without synchronous rotation, no additional driving system is required. And because two hatch doors can rotate 180 relatively, consequently the unmanned aerial vehicle of this disclosed embodiment can open the accommodation space of fuselage completely, consequently compare in the entry that present scheme can increase accommodation space, provide very big facility for the loading and unloading of goods. Therefore, unmanned aerial vehicle of the embodiment of the present disclosure can be used for transporting big article, has the wide beneficial effect of application range.

The specific structure of two doors in the unmanned aerial vehicle according to the embodiment of the present disclosure will be described below with reference to fig. 2, where fig. 2 schematically shows a perspective structure diagram of a partial structure of the unmanned aerial vehicle according to the embodiment of the present disclosure.

As shown in fig. 2, one door 11 of the two doors includes a first door body 111 and a catch mechanism 112. Correspondingly, the other door 12 of the two doors comprises a second door body 121 and a securing mechanism 122. The locking mechanism 112 and the fixing mechanism 122 can be engaged with or disengaged from each other under an external force, so as to lock or unlock the door 11 and the door 12.

The fastening mechanism 112 is disposed at an end of the first door body 111 close to the second door body 121, for example, the fastening mechanism 112 may be disposed on an inner surface (i.e., the first inner surface 1111) of the first door body 111. Accordingly, the fixing mechanism 122 is disposed at an end of the second door body 121 close to the first door body 111, for example, the fixing mechanism 122 may be disposed at an inner surface (i.e., the second inner surface 1211) of the second door body 121. When the fastening mechanism 112 and the fixing mechanism 122 are locked by an external force, one end of the first door body 111 close to the fastening mechanism 112 is attached to one end of the second door body 121 close to the fixing mechanism 122, so as to enclose the accommodating space 21 of the fuselage 20 into a closed space.

The fastening mechanism 112 and the fixing mechanism 122 may form a fastening mechanism, for example, the fastening mechanism 112 is a fastener in the fastening structure, and the fixing mechanism 122 is a grommet or a fixing seat in the fastening structure, which is not described in detail herein. Specifically, the fastening mechanism 112 may also be the fastening mechanism described in fig. 3, which includes a lock head, and the fixing mechanism 122 may be a lock catch, which is not limited in this disclosure.

According to the embodiment of the present disclosure, in order to ensure a stable connection between the machine head 10 and the machine body 20 when the door 11 is locked with the door 12, as shown in fig. 2, the machine body may be provided with at least one protrusion on a side surface 22 close to the machine head 10 in addition to a region where the rotating shaft is provided. Accordingly, at least one groove is provided on a side surface (i.e., the second side surface 1114) of the first door body 111 that abuts the side surface 22 of the body 20 and on a side surface (i.e., the third side surface 1212) of the second door body 121 that abuts the side surface 22 of the body, respectively. The size of the at least one groove is matched with that of the at least one bump, and the at least one groove corresponds to the arrangement position of the at least one bump. The at least one projection can be inserted into the at least one groove in a state that the hatch door 11 and the hatch door 12 are locked to close the accommodation space 21, thereby improving the connection stability of the head 10 and the body 20. According to an embodiment of the present disclosure, at least one groove may be disposed on the side surface 22 of the body 20, and at least one protrusion is disposed on the second side surface 1114 and the third side surface 1212, respectively, which is not limited by the present disclosure.

The structure of one of the two doors according to the embodiment of the present disclosure will be described in detail with reference to fig. 3 to 4C. Fig. 3 schematically shows a structural schematic diagram of one of two doors according to an embodiment of the present disclosure, fig. 4A schematically shows a partial structural schematic diagram of a fastening structure when the two doors are locked according to an embodiment of the present disclosure, fig. 4B schematically shows a partial structural schematic diagram of a fastening structure when the two doors are unlocked according to an embodiment of the present disclosure, and fig. 4C schematically shows a partial structural schematic diagram of a first door according to an embodiment of the present disclosure.

According to an embodiment of the present disclosure, as shown in fig. 3, the door 11 of the two doors includes a handle 113 in addition to the first door body 111 and the snapping mechanism 112. The handle 113 is disposed outside the outer surface 1113 of the first door body 111.

According to an embodiment of the present disclosure, as shown in fig. 3, the locking mechanism 112 may specifically include a transmission assembly 31, a moving assembly 32, and a lock head 33.

The transmission assembly 31 is disposed through the first door body 111 along a direction perpendicular to the outer surface 1113, one end of the transmission assembly 31 is connected to the handle 113, and the other end of the transmission assembly 31 can be hinged to the moving assembly 32. Accordingly, the first door body 111 may be provided with a receiving through-slot for receiving the transmission assembly 31, and the receiving through-slot may be sized to ensure that the transmission assembly 31 can rotate therein. Since one end of the transmission assembly 31 is connected to the handle 113, when the handle 113 rotates under the action of external force, the transmission assembly 31 is driven to rotate synchronously with the handle 113 in the accommodating through slot.

Wherein the moving assembly 32 is disposed on the first inner surface 1111 and extends along a circumferential direction of the first side surface 1112 of the first door body 111 (i.e. along an extending direction of an interface line of the first side surface 1112 and the first inner surface 1111), and the locking head 33 is fixedly connected to the moving assembly 32. Because the moving component 32 and the transmission component 31 are hinged to each other, when the transmission component 31 rotates, the transmission component 31 can drive the moving component 32 to move, so that the position of the locking head 33 is changed. When the door 11 and the door 12 are both engaged with the lateral surface 22 of the fuselage 20, the position of the lock head 33 can be changed by rotating the transmission assembly 31 by rotating the handle 113, and the relative position of the lock head 33 and the fixing mechanism 122 can be changed. Through the change of the relative position of the locking head 33 and the fixing mechanism 122, the locking head 33 can be matched with or separated from the fixing mechanism 122, so as to lock and unlock the cabin door 11 and the cabin door 12.

According to the embodiment of the present disclosure, the movement of the transmission assembly 31 to drive the moving assembly 32 may specifically be a movement along the circumferential direction of the first side surface 1112. As shown in fig. 3, the moving assembly may include a preload member 321 and a moving member 322 which are sequentially connected in a circumferential direction of the first side surface 1112. Wherein, the moving member 322 is hinged with the other end of the transmission assembly 31, and the lock head 33 is fixedly connected with the moving member 322. When the transmission assembly 31 rotates, the moving member 322 can be pulled to move along the circumferential direction by applying a force along the circumferential direction to the moving member 322.

The preload member 321 may be, for example, a spring, and when the transmission assembly 31 applies a force to the moving member 322 in the circumferential direction, the spring is pulled or compressed so that the spring is in an expanded state or a compressed state. After the locking head 33 is engaged with the fixing mechanism 122, or after the door 11 and the door 12 rotate relatively, under the action of the elastic force of the spring, the moving member 322 can be restored to the state before moving along the peripheral direction, and the driving assembly 31 and the handle are driven to rotate, so that the handle 113 is restored to the angle before applying the external force.

According to an embodiment of the present disclosure, as shown in fig. 3, the moving assembly 32 may further include a fixed sliding rail 323, for example, and the fixed sliding rail 323 is fixed to the first inner surface 1111 of the first door body 111. Accordingly, the preload member 321 and the moving member 322 are disposed in the fixed slide 323 to limit the moving member 322 to move in the fixed slide 323 along the circumferential direction of the first side surface 1112, and to prevent the moving member 322 from moving in a direction perpendicular to the circumferential direction.

According to an embodiment of the present disclosure, as shown in fig. 4A to 4B, in order to enable the transmission assembly 31 to apply a force to the moving assembly 32 in a circumferential direction, the transmission assembly 31 may specifically include a transmission shaft 311 and a pick 312.

The transmission shaft 311 penetrates through the first door body 111, that is, the transmission shaft 311 is inserted into the accommodating through slot, and a first end of the transmission shaft 311 is fixedly connected with the handle 113. The driving shaft 311 may be rotated in synchronization with the handle 113 when the handle 113 is rotated by an external force.

The shifting piece 312 is disposed on the transmission shaft 311 and located between the first door body 111 and the second end of the transmission shaft 311 opposite to the first end. Specifically, the shifting piece 312 may be provided with a fixing hole, and when the shifting piece 312 is sleeved on the transmission shaft 311, the transmission shaft 311 is located in the fixing hole. The size of the fixing hole may be matched with the size of the transmission shaft 311, so that the driving plate 312 may rotate synchronously with the transmission shaft 311 when the transmission shaft 311 rotates.

According to the embodiment of the present disclosure, the pick 312 may, for example, extend in a direction perpendicular to the transmission shaft 311 (i.e., a direction perpendicular to a connection line between the first end and the second end of the transmission shaft) to a direction away from the transmission shaft 311, protrude from the transmission shaft 311, and may contact with the moving component 32. Then as the paddle 312 rotates with the drive shaft 311, a force may be applied to the moving assembly 32 such that the moving assembly 32 moves in a circumferential direction of the first side surface 1112.

According to an embodiment of the present disclosure, as shown in fig. 4A to 4B, the pick 312 may specifically include, for example, a first through groove 41 disposed in a direction perpendicular to the first door body 111. When the pick 312 is fixedly connected to the transmission shaft 311, the first through groove 41 is located at one side of the transmission shaft 311. In order to ensure that the pull tab 312 has a small size, the first through groove 41 may be located at an end of the pull tab 312 away from the transmission shaft 311.

Accordingly, the moving assembly 32 further includes fixing posts 324 protruding in a direction perpendicular to the first inner surface 1111 of the first door body 111. The fixing post 324 may be fixed to the moving member 322. According to the embodiment of the disclosure, the fixing post 324 is movably inserted into the first through groove 41. Correspondingly, the dimension of the first through groove 41 in the direction perpendicular to the connecting line of the first end and the second end of the transmission shaft 311 and the direction away from the transmission shaft 311 is larger than the dimension of the fixing post 324. The dimension of the first through groove 41 in the direction perpendicular to both the direction away from the transmission shaft 311 and the direction of the connecting line of the first end and the second end of the transmission shaft 311 is matched with the fixing column 324. When the pulling piece 312 and the transmission shaft 311 rotate synchronously, the pulling piece 312 provides a force along the rotation direction to the transmission shaft 311, so that the fixing post 324 can move in the first through groove 41 along a direction away from the transmission shaft 311 relative to the first through groove 41, and the fixing post 324 can drive the moving assembly 32 to move along the circumferential direction of the first side surface 1112.

According to the embodiment of the present disclosure, the rotatable angle of the handle 113 under the action of the external force corresponds to the distance that the fixing column 324 can move in the first through groove 41 along the circumferential direction, that is, the rotatable angle of the handle 113 matches the size of the first through groove 41 in the direction perpendicular to the connecting line of the first end and the second end of the transmission shaft 311 and the direction away from the transmission shaft 311. For example, the handle 113 is rotatable by an angle of 90 ° by an external force.

According to an embodiment of the present disclosure, in order to avoid the handle 113 adding extra resistance to the flight of the drone, as shown in fig. 4C, a fixing groove 42 matching the size of the handle 113 is provided on the outer surface 1113 of the first door body 111. When the two doors need to be unlocked, the handle 113 can be pulled out from the fixing groove 42 under the action of external force, and the handle 113 is rotated to drive the poke piece to rotate, so that the moving assembly 32 moves in the direction of the arrow in fig. 4B, and the locking head 33 is separated from the fixing mechanism 122. After the two doors are unlocked, when the two doors need to be locked, the handle 113 may be rotated to drive the paddle to rotate, so that the moving assembly 32 moves along the arrow direction in fig. 4A, and then the handle 113 is pressed along the direction perpendicular to the first door body 111 to buckle the handle 113 into the fixing groove 42, so that the locking head 33 is engaged with the fixing mechanism 122.

According to the embodiment of the present disclosure, in the case that the preload member 321 of the moving assembly 32 is a spring, after the two doors are unlocked, the handle 113 can be automatically rotated to the angle before the fixing groove 42 is pulled out by the elastic force of the spring. When two doors need to be locked, the handle 113 is pressed along a direction perpendicular to the first door body 111, and the handle 113 is buckled in the fixing groove 42.

According to an embodiment of the present disclosure, in order to enable the handle 113 to be automatically snapped into the fixing groove 42 after the handle 113 is rotated to unlock the two doors, as shown in fig. 4A to 4C, the driving assembly 31 may further include an end plate 313 and an elastic member 314. The end plate 313 is fixedly connected to the second end of the transmission shaft 311, and the elastic member 314 is sleeved on the transmission shaft 311 and located between the pick 312 and the end plate 313. The elastic member 314 is compressed during the process of pulling the handle 113 out of the fixing groove 42, and after the external force is withdrawn, the handle 113 can move in the direction approaching the door 11 in the direction perpendicular to the outer surface 1113 under the elastic force of the elastic member 314 until buckling into the fixing groove 42, so that the elastic member 314 returns to the natural state.

According to the embodiment of the present disclosure, in order to limit the moving distance of the lock head 33, as shown in fig. 4A to 4B, the locking mechanism 112 further includes a limiting piece 34. The limiting member 34 is fixed to the first inner surface 1111 of the first door body 111, and the limiting member 34 has a second through slot 43. Specifically, as shown in fig. 4C, the second through groove 43 is composed of a first sub groove 431 and a second sub groove 432 communicating with each other. The first sub-groove 431 extends along the circumferential direction of the first side surface 1112, and the moving element 32 is inserted into the first sub-groove 431 to move in the first sub-groove 431 along the circumferential direction. The second sub-groove 432 may extend from a central position of the stopper 34 toward a direction near the first side surface 1112. The second sub-groove 432 may be open opposite to the first side surface 1112, and the locking head 33 is fixed to the moving assembly 32 at the position of the second sub-groove 432 and protrudes from the second sub-groove 432. Wherein the dimension of the second sub-groove 432 in the circumferential direction is larger than the dimension of the protruding portion of the locking head 33, and the dimension in the direction perpendicular to the door 11 matches the dimension of the protruding portion of the locking head 33, so that the protruding portion of the locking head 33 can move relative to the second sub-groove 432 when the moving assembly 32 moves in the circumferential direction. For example, as shown in fig. 4A, the locking head 33 is located at one end of the second sub-groove 432 in the circumferential direction when the two doors are locked to each other, and as shown in fig. 4B, the locking head 33 is located at the other end of the second sub-groove 432 in the circumferential direction when the two doors are unlocked from each other.

Fig. 5A schematically shows a structure of the lock cylinder cooperating with the lock catch according to the first embodiment of the present disclosure.

According to the embodiment of the present disclosure, as shown in fig. 4A to 4C, the portion of the locking head 33 protruding from the second sub-groove 432 may be, for example, a hook-shaped structure, and in particular, may be an inverted "L" type structure, so that a semi-closed groove may be defined between the hook-shaped structure and the limiting member 34. the fixing mechanism 122 may specifically include, for example, the lock catch 51 shown in fig. 5A, the lock catch 51 extends toward the inside of the door 12 along the fourth side surface 1213 of the door 12, wherein a dimension of the semi-closed groove in a direction perpendicular to the first side surface 1112 matches a dimension of the lock catch 51.

When it is desired to lock two doors, the lock head 33 is moved in the second sub-slot 432 in the direction of the arrow in fig. 4A by moving the moving assembly 32, so that the lock head 33 is close to the lock catch 51, and the lock catch 51 is inserted between the hook-shaped structure and the stopper 34. Finally, the lock catch 51 is in the position shown in fig. 5A, i.e. is clamped in the semi-closed slot, so as to lock the hatch 11 and the hatch 12.

Conversely, when it is necessary to unlock the two doors, the locking head 33 is moved in the second sub-groove 432 in the direction of the arrow in fig. 4B by moving the moving assembly 32 in the opposite direction, so that the locking head 33 is separated from the lock catch 51, and the lock catch 51 is pulled out from the semi-closed groove, thereby unlocking the door 11 from the door 12.

Fig. 5B schematically shows a structure of the lock cylinder cooperating with the lock catch according to the second embodiment of the present disclosure.

According to an embodiment of the present disclosure, in order to further improve the locking stability of the door 12 of the door 11, as shown in fig. 5B, the latch 51 may be provided with, for example, a third through groove 511 extending in a direction perpendicular to the fourth side surface 1213 of the second door body, and the size of the third through groove 511 in the extending direction of the fourth side surface 1213 is matched with the size of the hook structure, so that the hook structure of the locking head 33 can penetrate into the third through groove 511. Further, the third through-slot 511 should have a smaller dimension in a direction perpendicular to the fourth side surface 1213 than the dimension of the hook structure in a direction perpendicular to the first side surface 1112 so that the hook structure can protrude from the third through-slot 511 after penetrating into the third through-slot 511.

When the accommodating space 21 needs to be closed, the two cabin doors can be pushed firstly, so that the two cabin doors are attached to the fuselage; then, the handle is pulled out from the fixing groove 42, and then the handle is rotated to drive the moving assembly 32 to move, so as to drive the locking head 33 to move in the second sub-groove 432 along the arrow direction in fig. 4B, so that the locking head 33 moves to the position corresponding to the third through-groove 511. The hook-shaped structure of the locking head 33 is inserted into the third through-groove 511 and protruded from the third through-groove 511 by the elastic force of the elastic member 314 after the external force is withdrawn. Then, under the elastic force of the pre-tightening member, the locking head 33 is driven to move in the second sub-groove 432 along the arrow direction in fig. 4A, and finally, as shown in fig. 5B, the lock catch 51 is clamped in the semi-closed groove between the hook-shaped structure and the limiting member 34, so as to lock the cabin door 11 and the cabin door 12.

On the contrary, when the accommodating space 21 needs to be opened, the handle is pulled out from the fixing groove 42, and then the handle is rotated to drive the moving assembly 32 to move, so as to drive the locking head 33 to move in the second sub-groove 432 along the arrow direction in fig. 4B, so that the hook-shaped structure of the locking head 33 moves to the position corresponding to the third through groove 511, and the door 11 and the door 12 are unlocked. Then, the hatch 11 and the hatch 12 are pushed to rotate relatively, the hook-shaped structure of the lock head is pulled out from the third through groove 511, and the accommodating space 21 is opened.

To sum up, the unmanned aerial vehicle of this disclosed embodiment, through the design of aircraft nose run-to-run hatch door, for the design of fuselage afterbody run-to-run hatch door, reduced the structural design degree of difficulty, avoided pneumatic adverse effect. And because two hatch doors rotate the back relatively, can open accommodation space completely, can provide great operating space for the goods handling to make things convenient for the loading and unloading of goods. Compared with the design of the cabin door with the head rotated upwards, the design of the cabin door with the head split open in the embodiment of the disclosure does not need to additionally increase a hydraulic driving mechanism, thereby having the advantage of lighter overall structure weight.
