Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to an automatic propeller retracting mechanism for an unmanned aerial vehicle hangar. Background Art

[0002] The existing automatic hangars for drones cannot touch the drone blades when the hatch is closed, otherwise the drone blades will be crushed or even broken when the hangar hatch is closed. Therefore, the hangar's outer dimensions need to be designed to be large, so that the inner cavity has enough space to accommodate the drone and maintain a certain safe distance from the drone blades. Utility Model Content

[0003] In order to solve the above problems, the utility model proposes an automatic propeller retracting mechanism for a UAV hangar. When the inner cavity size of the UAV hangar is smaller than the size of the drone, the propeller retracting mechanism can retract the propeller blades of the UAV to a suitable position to avoid direct contact between the hatch cover and the propeller blades of the UAV.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] An automatic propeller retracting mechanism for a drone hangar, the drone hangar comprising a rotatable or flippable hatch, including

[0006] The propeller retracting seat is installed at the edge of the hatch near where it is fastened to the main body of the drone hangar;

[0007] A movable connection component is installed on the paddle retracting seat;

[0008] A paddle retracting member connected to the paddle retracting seat via a movable connecting member;

[0009] The paddle retracting member has a curved edge with a continuous and smooth transition toward the hatch cover buckling direction, so that when it contacts the drone blade, it can push the drone blade to rotate and retract into the edge where the hatch cover and the drone hangar body buckle.

[0010] Preferably, the cross section of the main body of the hatch cover is "U"-shaped.

[0011] Preferably, the propeller retracting seat and the propeller retracting member are located on the inner side of the hatch cover side wall.

[0012] Preferably, the paddle retracting member is a paddle retracting blade with a curved plate-like structure.

[0013] Preferably, the paddle retracting blade has a certain extension length, the first end of the paddle retracting blade is connected to the movable connecting component, the second end of the paddle retracting blade is a free end, and the middle part of the paddle retracting blade protrudes in a direction away from the side wall of the cabin cover.

[0014] Preferably, when the retractable blade is in a free state, the lower edge of the retractable blade protrudes from the edge where the hatch cover and the UAV hangar body are buckled.

[0015] Preferably, the movable connecting component is a rotating shaft, and the paddle retracting member is connected to the paddle retracting seat via the rotating shaft.

[0016] Preferably, the movable connection component is a linear guide component.

[0017] The beneficial effects of using the utility model are:

[0018] The automatic propeller retracting mechanism of the drone hangar is installed on the hatch cover of the drone hangar, and the propeller retracting member is slightly protruding. When the hatch cover is closed, if the drone blades are on the moving path of the hatch cover's buckling edge, the propeller retracting member will first contact the drone blades. By utilizing the arc contact surface of the propeller retracting member, in addition to the vertical downward force on the drone blades, the drone blades can also provide lateral force and push away the drone blades, thereby preventing the hatch cover from directly contacting the drone blades.

[0019] The automatic propeller retraction mechanism of the UAV hangar does not require an additional active power structure, and can be linked according to the opening and closing process of the cabin door to achieve the retraction of the UAV blades and the retracting blades.

[0028] In order to make the purpose, technical solution and advantages of the technical solution more clear, the technical solution is further described in detail below in conjunction with specific implementation methods. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the technical solution.

[0029] In order to avoid the problem in the prior art that the hatch cover 10 hits the drone blades 30 when closing, causing the drone blades 30 to be crushed or even broken when the hangar hatch cover 10 is closed, as shown in FIG. Figure 1 As shown, this embodiment proposes an automatic propeller retracting mechanism for a drone hangar. Specifically, the automatic propeller retracting mechanism for a drone hangar is installed at the hatch 10. Figure 3 As shown, the drone hangar includes a rotatable or flippable hatch cover 10, and the cross section of the main body of the hatch cover 10 is "U" shaped. The drone hangar automatic propeller retracting mechanism is installed on the hatch cover side wall 11. The hatch cover 10 flips backward from the front end of the drone hangar. During the flipping process, the drone blades 30 are on the moving path of the buckled edge of the hatch cover 10, that is, Figure 1 The blade interference portion 31 is located in the middle.

[0030] In the present embodiment, the propeller seat 21 in the automatic propeller retracting mechanism of the drone hangar is fixed to the inner side of the hatch cover side wall 11, and the rotating shaft 22 is installed on the side of the propeller seat 21 close to the front end of the hatch cover 10. The propeller blade 23 has a certain extension length and forms a blade-shaped or wing-shaped structure. When the hatch cover 10 is flipped open, the propeller blade 23 is in a free state. The lower side of the propeller blade 23 is successively composed of the first edge section 231, the second edge section 232 and the third edge section 233 from the end adjacent to the rotating shaft 22 to the free end, and the first edge section 231, the second edge section 232 and the third edge section 233 have a smooth transition and are continuous curves. In the lateral projection of the second edge section 232 and the fastening edge of the hatch cover 10, the angle between the second edge section 232 and the hatch cover 10 is relatively large. Therefore, when the hatch cover 10 is rotated or flipped over to be fastened on the UAV hangar, if the UAV blade 30 is on the moving path of the fastening edge of the hatch cover 10, the lower edge of the retracting blade 23 will first contact the UAV blade 30. By utilizing the arc contact surface of the retracting blade, in addition to the vertical downward force on the UAV blade 30, it can also provide lateral force and push the UAV blade 30 away, thereby preventing the hatch cover 10 from directly contacting the UAV blade 30.

[0031] like Figure 2 As shown, when the hatch 10 is fully closed, the drone blades 30 are completely stored in the drone hangar.

[0032] In some feasible embodiments, the retracting blade 23 can also be connected to the retracting blade seat 21 through other movable connection components, such as a linear drive component. The function of the movable connection component is that when the retracting blade 23 completes the retracting action on the drone blade 30, the hatch 10 continues to rotate or flip, and the retracting blade 23 is acted on by the movable connection component so that the retracting blade 23 contacts the physical component of the drone hangar, such as the platform surface, and the retracting blade 23 can be pressed and moved for a short distance before being retracted into the hatch 10.

[0033] like Figure 3As shown, the paddle retracting member is a paddle retracting blade 23 of a curved plate-like structure. The paddle retracting blade 23 has a certain extension length, the first end of the paddle retracting blade 23 is connected to the movable connection component, the second end of the paddle retracting blade 23 is a free end, and the middle part of the paddle retracting blade 23 protrudes in the direction away from the hatch cover side wall 11. The structure in which the middle part of the paddle retracting blade 23 protrudes in the direction away from the hatch cover side wall 11 can make the paddle retracting blade 23 have a better paddle retracting effect, and at the same time can fully contact the physical parts of the drone hangar so as to be retracted into the hatch cover 10, and the final buckled state is as shown in FIG. Figure 4 shown.

[0034] The paddle retracting mechanism automatically realizes the function of retracting the drone blades 30 with the opening and closing of the hatch 10, without the need for additional electronic and electrical control. The paddle retracting mechanism is installed on both sides of the hatch 10, which is the best force position for the drone blades 30 and is most conducive to the retraction of the drone blades 30.

[0035] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, many changes can be made in the specific implementation methods and application scopes based on the ideas of the present technical content. As long as these changes do not deviate from the concept of the present invention, they all fall within the scope of protection of this patent.
