Description

Technical Field

[0001] The present invention relates to the technical field of hangars, and in particular to a fixed-propeller UAV hangar. Background Art

[0002] With the rapid development of the Internet and the Internet of Things, drone products have been widely used in many fields in modern society, such as forestry, power grid, sea area, surveying and mapping and other related industries. Drones can complete tasks such as reconnaissance, detection, and inspection. However, a single drone operation system still needs to rely on a lot of personnel to ensure it, and the professional level of the support personnel is required to be high. This means that a single drone operation system has not achieved true unmanned operation. Therefore, a drone operation system that can operate without human participation, that is, a drone hangar system, was born.

[0003] In recent years, drone hangar systems have gradually entered the public's field of vision. Drone hangars refer to drone systems that can automatically return drones to their original positions, store them, maintain them, and charge them. The entire process of drone operations is controlled by the system itself, without the need for human involvement.

[0004] The drone hangar systems that are currently widely used are mainly multi-blade drone hangars, and most of them are consumer-grade drone hangar systems.

[0005] The prior art drone hangar includes a hangar frame, in which a parking platform, a lifting mechanism, a power supply mechanism, etc. are arranged. An opening is arranged at the top of the hangar frame, and a hangar door mechanism is arranged at the opening position, and the hangar is opened or closed by controlling the hangar door structure. When the hangar is opened, the drone inside can fly out of the hangar.

[0006] The propeller drone includes a fuselage, an arm is arranged on the upper side of the fuselage, and propeller blades are installed on the arm. Since the wings of the propeller drone have an envelope size when rotating, the propeller blade envelope size needs to be considered when designing the drone hangar in the prior art. Therefore, when designing the size of the drone hangar, the size needs to be increased to allow the drone blades to enter the hangar. Since the hangar is relatively large, the transportation cost is increased to a certain extent. Summary of the invention

[0007] 1. Technical issues to be solved In view of the deficiencies in the prior art, the present invention provides a fixed-propeller UAV hangar, which can move the UAV blades when the UAV is parked on a receiving platform and descends, thereby avoiding interference between the blades and the hangar frame.

[0008] (II) Technical solution To achieve the above-mentioned objectives, an embodiment of the present application provides a fixed-propeller UAV hangar, including a hangar frame, a hangar opening formed in the middle of the hangar frame, a receiving platform is arranged on the inner side of the hangar frame, and a lifting device for controlling the vertical upward and downward movement of the receiving platform is arranged inside the hangar frame and located under the receiving platform; a paddle mechanism for moving and positioning the blades is arranged between the vertical inner wall of the hangar frame and the vertical side wall of the receiving platform.

[0009] Preferably, the paddle shifting mechanism comprises a guide plate fixed on the vertical inner wall of the hangar frame; a track is arranged on the guide plate, and a paddle shifting assembly for shifting and positioning the paddle blades is arranged on the vertical side wall of the receiving platform close to the guide plate.

[0010] Preferably, the paddle assembly includes a fixed seat fixed to the lower end of the receiving platform, and two rotating connecting shafts are installed on the fixed seat at intervals; a rotating plate is rotatably connected to each of the rotating connecting shafts, and the rotating plate is parallel to the guide plate, and a positioning guide wheel is rotatably installed on a side of the rotating plate close to the guide plate and at an end away from the rotating connecting shaft, and the positioning guide wheel is embedded in the track and can slide in the track; the two rotating connecting shafts are located on a side close to the middle of the fixed seat, and the positioning guide wheel is located on a side close to both ends of the fixed seat; a shift rod is fixedly installed on one end of the rotating plate close to the positioning guide wheel.

[0011] Preferably, the tracks are symmetrically arranged in two groups, each including a vertically arranged first track and an obliquely arranged second track; the first track is located at one end close to the bottom of the hangar frame, and the first track and the rotating connecting axis are located in the same vertical plane; the second track is connected to the first track, and the end of the second track away from the first track is inclined toward the end away from the rotating connecting axis, and the distance between the rotating connecting axis and the end of the second track away from the first track is the same as the distance between the rotating connecting axis and the positioning guide wheel.

[0012] Preferably, a rotating sleeve is sleeved on the outer side of the shifting rod, and the rotating sleeve and the shifting rod are rotatably connected via a bearing.

[0013] Preferably, the paddle mechanisms are symmetrically arranged in two groups on two relatively parallel sides of the hangar frame.

[0015] Preferably, a returning mechanism for moving the parked UAV to return it to its final parking position is provided on the upper side of the receiving platform.

[0016] (III) Beneficial effects The present invention provides a fixed-propeller UAV hangar. When the UAV lands on the receiving platform, the UAV is controlled to move to a position by a homing mechanism. When the lifting device controls the receiving platform to land into the hangar frame, the paddle assembly is synchronously driven to swing, and the UAV blades are moved to avoid interference between the blades and the hangar frame. In this way, the unnecessary size of the hangar can be reduced and the transportation burden can be reduced. At the same time, by using the paddle mechanism provided on the hangar to make the UAV blades fluctuate, it is possible to avoid installing a fixed-propeller motor on the UAV, thereby reducing the weight of the UAV. At the same time, when the paddles are moved, they are synchronously driven by the lifting device, thereby avoiding further increasing the drive structure, simplifying the control system, and reducing the failure rate of the hangar.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example The present invention provides a fixed-propeller UAV hangar, see Figure 1-Figure 4 , including a hangar frame 100, a hangar opening is formed in the middle of the hangar frame 100, a receiving platform 200 is arranged inside the hangar frame 100, and a lifting device 300 is arranged inside the hangar frame 100 and located at the lower side of the receiving platform 200 to control the receiving platform 200 to move up and down in the vertical direction; a paddle mechanism 400 for moving and positioning the blades is arranged between the vertical inner wall of the hangar frame 100 and the vertical side wall of the receiving platform 200. When the UAV lands and returns to its position, the receiving platform 200 is controlled by the lifting device 300 to enter the hangar frame 100. During the landing process, the blades of the UAV are arranged by the paddle mechanism 400, so that the blades are rotated to an appropriate angle, and then the UAV can enter the inside of the hangar frame 100.

[0021] Specifically, the paddle mechanism 400 includes a guide plate 410 fixed on the vertical inner wall of the hangar frame 100; a track is provided on the guide plate 410, and a paddle assembly 420 for moving and positioning the paddle blades is provided on the vertical side wall of the receiving platform 200 close to the guide plate 410.

[0022] The paddle assembly 420 includes a fixing base 421 fixed to the lower end of the receiving platform 200 , and two rotating connecting shafts 422 are installed on the fixing base 421 at intervals.

[0023] A rotating plate 423 is rotatably connected to each rotating connecting shaft 422. The rotating plate 423 is parallel to the guide plate 410. A positioning guide wheel 424 is rotatably installed on a side of the rotating plate 423 close to the guide plate 410 and at an end away from the rotating connecting shaft 422. The positioning guide wheel 424 is embedded in the track and can slide in the track.

[0024] The two rotating connecting shafts 422 are located on one side close to the middle of the fixing seat 421 , and the positioning guide wheels 424 are located on one side close to both ends of the fixing seat 421 . A lever 425 is fixedly installed on one end of the rotating plate 423 close to the positioning guide wheels 424 .

[0025] There are two groups of tracks symmetrically arranged, each including a vertically arranged first track 411 and an obliquely arranged second track 412; the first track 411 is located at one end close to the bottom of the hangar frame 100, and the first track 411 and the rotating connecting shaft 422 are located in the same vertical plane; the second track 412 is connected to the first track 411, and the end of the second track 412 away from the first track 411 is inclined toward the end away from the rotating connecting shaft 422, and the distance between the rotating connecting shaft 422 and the end of the second track 412 away from the first track 411 is the same as the distance between the rotating connecting shaft 422 and the positioning guide wheel 424. During operation, when the lifting device 300 controls the receiving platform 200 to move in the vertical direction, the fixed seat 421 synchronously drives the rotating plate 423 to move. During the movement, the positioning guide wheel 424 slides in the track. When the positioning guide wheel 424 slides into the first track 411, the lever 425 is in a vertical position. When the positioning guide wheel 424 is in the second track 412, the lever is gradually tilted to the horizontal until it is horizontal. Furthermore, when the lifting device 300 controls the receiving platform 200 to descend, it can synchronously drive the paddle mechanism 400 to paddle the drone blades.

[0026] Preferably, a rotating sleeve 426 is sleeved on the outer side of the lever 425, and the rotating sleeve 426 and the lever 425 are rotatably connected via a bearing. The rotating sleeve 426 can rotate with the blade when the blade is moved, thereby reducing the friction between the blade and the blade, thereby avoiding scratching the blade and increasing the service life of the device.

[0027] Two groups of paddle mechanisms 400 are symmetrically arranged on two relatively parallel sides of the hangar frame 100.

[0028] The lifting device 300 includes a support frame 310 installed on the lower side of the receiving platform 200, and a lifting support sleeve 320 is provided on a side of the support frame 310 away from the receiving platform 200.
