Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a locking and opening structure of a mouth cover of an unmanned aerial vehicle. Background Art

[0002] At present, drones have higher and higher requirements for stealth and the outer surface of the fuselage. However, most drones currently need to rely on a launch pad or thrust rod to eject the aircraft. When launching, the launch cover on the drone body needs to be opened, and then the cover needs to be automatically closed and locked during the flight to ensure that the cover does not protrude from the surface of the fuselage due to the pressure difference during the flight. Before the next flight, it is also necessary to open the cover on the fuselage conveniently. In order to facilitate the opening of the locked cover, the current solution is to add a small cover to the cover, but adding a small cover will increase the work of repairing the cover and increase the difficulty of matching. For example, according to the standard small cover, it is necessary to have serrations. If the small cover is matched with the entrance cover, it is necessary to make a depression on the skin of the cover to ensure that the small cover does not protrude from the fuselage. Summary of the invention

[0003] In order to solve the technical problem in the prior art that the drone cover needs to be automatically closed after launch and cannot be opened again during flight, the present application proposes a drone cover locking and opening structure to solve the above technical problem.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] The utility model provides a locking and opening structure of a drone mouth cover, comprising: a reset hinge, which is connected between the drone body and the mouth cover to automatically reset the mouth cover and close the mouth cover after the drone is detached from a launch pad; a lock assembly, which comprises a lock body fixed on the drone body, the lock body being provided with a retractable lock pin and a button for controlling the extension of the lock pin; a lock slot frame, which is fixed on the mouth cover and is provided with a lock slot for receiving the lock pin extending from the lock body; and a trigger, which is connected to the mouth cover to press the button on the lock body when the mouth cover is closed.

[0006] Furthermore, the end of the locking pin extending out of the lock body and inserted into the lock slot is the pressing end of the locking pin, and a guide hole is provided on the fuselage surface of the drone facing the end face of the pressing end, so that an external rod-shaped object can enter the fuselage through the guide hole to push the pressing end of the locking pin out of the lock slot.

[0007] Furthermore, the guide hole is provided with a hollow guide column for guiding the external rod-shaped object.

[0008] Furthermore, the trigger member is movably connected to the cover so as to adjust the distance between the trigger member and the button when unlocking.

[0009] Furthermore, the trigger member is screwed onto the mouth cover.

[0010] Furthermore, the trigger member is a countersunk screw, and the screw cap of the countersunk screw is arranged on the side of the cover facing outwards. At the same time, a recessed portion is arranged on the cover to accommodate the screw cap of the countersunk screw.

[0011] Furthermore, the countersunk screw is screwed onto the opening cover via a supporting plate nut, and the supporting plate nut is fixed on a side of the opening cover facing the interior of the fuselage.

[0012] Furthermore, a nut is fixedly connected to one end of the countersunk screw that presses the button on the lock body.

[0013] Furthermore, the lock body is fixed on the fuselage of the drone via a bracket.

[0014] Based on the above technical solution, the technical effects that can be achieved by the utility model are:

[0015] The UAV cover locking and opening structure of the utility model has the following advantages: when the UAV leaves the launch platform, the cover automatically resets the cover under the action of the reset hinge to close the cover; during the process of resetting the cover, the trigger member on the cover presses the button on the lock body to control the lock pin to extend out of the lock body and enter the lock slot on the lock slot frame to lock the cover, thus completing the locking. This solves the technical problem in the prior art that the UAV cover needs to be automatically closed after launch and cannot be opened again during flight.

[0016] The locking and opening structure of the drone cover of the utility model is that, in order to facilitate unlocking, the end of the lock pin extending out of the lock body and inserted into the lock slot is the pressing end of the lock pin, and a guide hole is provided on the fuselage surface of the drone body opposite to the end surface of the pressing end, so that an external rod-shaped object can enter the fuselage through the guide hole to push the pressing end of the lock pin out of the lock slot. This unlocking method does not require adding a small cover to the cover, which reduces the repair work of the cover. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] like Figure 1-2 As shown, the utility model provides a locking and opening structure of a drone cover, including a reset hinge 1, a lock assembly 2, a lock slot frame 3 and a trigger 4. The reset hinge 1 is connected between the fuselage a of the drone and the cover b to automatically reset the cover b after the drone is detached from the launch pad to close the cover b. The reset hinge 1 is preferably a spring hinge. The lock assembly 2 includes a lock body 21 fixed on the fuselage a of the drone, and a retractable lock pin 22 and a button 23 for controlling the lock pin 22 to extend are arranged on the lock body 21. The lock slot frame 3 is fixed on the cover b, and a lock slot is opened on the lock slot frame 3 to receive the lock pin 22 extending from the lock body 21. The trigger 4 is connected to the cover b to press the button 23 on the lock body 21 when the cover b is closed.

[0022] The UAV cover locking and opening structure of the utility model has the following advantages: when the UAV leaves the launch pad, the cover b is automatically reset under the action of the reset hinge 1 to close the cover b; during the process of resetting the cover b, the trigger member 4 on the cover b presses the button 23 on the lock body 21 to control the lock pin 22 to extend out of the lock body 21 and enter into the lock slot on the lock slot frame 3 to lock the cover b, thereby completing the locking, thereby solving the technical problem in the prior art that the cover b of the UAV needs to be automatically closed after launch and cannot be opened again during flight.

[0023] In order to facilitate unlocking, the end of the lock pin 22 extending out of the lock body 21 and inserted into the lock slot is the pressing end 221 of the lock pin 22. A guide hole is provided on the surface of the fuselage a of the drone that is opposite to the end surface of the pressing end 221, so that an external rod-shaped object can enter the fuselage a through the guide hole to push the pressing end 221 of the lock pin 22 out of the lock slot. This unlocking method does not require adding a small cover b to the cover b, which reduces the repair work of the cover b.

[0024] In order to further facilitate unlocking, the guide hole is provided with a hollow guide column 5 for guiding the external rod-shaped object. The hollow guide column 5 is added so that the external rod-shaped object can accurately find the position of the pressing end 221 of the lock pin 22, and the hollow guide column 5 can also provide a certain support effect for the external rod-shaped object.

[0025] In order to prevent the trigger member 4 from being pressed too tightly against the button 23 during the unlocking process, thereby interfering with the lock pin 22 and affecting the unlocking, the trigger member 4 is movably connected to the cover b to adjust the distance between the trigger member 4 and the button 23 when unlocking.

[0026] Specifically, the trigger member 4 is screwed onto the cover b to facilitate adjustment of the distance between the trigger member 4 and the button 23 .

[0027] Furthermore, the trigger member 4 is a countersunk screw 41, and the screw cap of the countersunk screw 41 is arranged on the side of the cover b facing outward. At the same time, a recessed portion is arranged on the cover b to accommodate the screw cap of the countersunk screw 41, thereby ensuring that there are no protruding parts on the fuselage a to affect the flight during the flight of the drone.

[0028] Furthermore, the countersunk screw 41 is screwed on the cover b through the support plate nut 42, and the support plate nut 42 is fixed on the side of the cover b facing the inside of the fuselage a. The countersunk screw 41 and the support plate nut 42 cooperate, the countersunk screw 41 will not damage the cover b, and can be used multiple times.

[0029] In a specific embodiment of the utility model, a nut 43 is fixedly connected to one end of the countersunk screw 41 that presses the button 23 on the lock body 21, and the nut 43 can be screwed on the countersunk screw 41 with glue to achieve a fixed connection between the two. The countersunk screw 41 and the nut 43 are screwed in with glue to press the button 23, which increases the contact area with the button 23 and improves the accuracy. At the same time, since the surface of the mouth cover b is smooth and has no grip, the countersunk screw 41 on the outer surface of the mouth cover b can be used as a force point for pulling the mouth cover b, killing two birds with one stone.

[0030] In a specific embodiment of the present invention, the lock body 21 is fixed on the fuselage a of the drone via a bracket 6 .

[0031] It should be understood that the specific embodiments described above are only used to explain the present invention, and are not used to limit the present invention. Obvious changes or modifications derived from the spirit of the present invention are still within the scope of protection of the present invention.
