Description

Technical Field

[0001] The utility model relates to the field of a propeller-retracting device and a helipad for an unmanned aerial vehicle, and in particular to a propeller-retracting device and a helipad for an unmanned aerial vehicle. Background Art

[0002] At present, multi-rotor drones often use the method of fixing the arm and the fuselage as one, which will greatly increase the floor space of the drone when it is in standby mode, which is not conducive to the storage and collection of the drone, nor is it conducive to its transportation and transfer. Although some drones also use a folding arm structure, most of the folding arm structures use aluminum alloy, which makes the arm cost higher, heavier, and has lower production efficiency; and because the implementation method is more complicated or time-consuming, it fails to achieve the purpose of quick storage and collection. The folding arm structure is mainly composed of blades and a fixed shaft, wherein the fixed shaft rotates with the fixed axis of the motor, and the fixed shaft is connected to the blades in a rotatable connection. During the normal flight of the drone, the motor rotates to drive the blades to keep rotating in a straight line; after the flight ends and the docking, the blades converge with inertia. However, the inertial convergence of the current drone folding propeller after docking is random, and often requires manual secondary confirmation and re-tightening, which not only increases the cumbersome workload, but also requires the size of the docking apron to increase to meet the storage of the drone body and blades, which is not conducive to miniaturization.

[0003] Chinese patent publication number CN108945502B discloses an automatic storage device for drones that can reduce the volume, which relates to the field of drone technology and solves the problems of low space utilization, large volume, heavy weight and high cost of existing drone storage devices. The device includes: a helipad on the upper surface for parking drones, a helipad cover that is movably connected to the helipad; a motor connected to the helipad cover, and the helipad cover can be covered on the upper surface of the helipad when the motor is running; a control system connected to the motor for electrical connection; an infrared camera set on the helipad, connected to the control system, and photographing the propeller blades of the drone; the control system is used to receive the picture sent by the infrared camera and analyze the picture to obtain the picture analysis result, and the control system controls the infrared camera to shoot, the electronic speed regulator or the motor according to the picture analysis result. By using the control system, the infrared camera and the electronic speed regulator to control the rotation of the propeller blade, the space utilization rate is high, the volume of the storage device is greatly reduced, and the weight and processing cost of the storage device are reduced. The patent uses an infrared camera to take the picture of the propeller blade and then adjusts it by an electronic speed regulator or a motor, which is costly and increases the cost of the helipad. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the inertial convergence of the folding propellers of the current UAV after docking is random, and often requires manual secondary confirmation and re-tightening, which not only increases the tedious workload, but also requires the size of the docking apron to be increased to accommodate the storage of the UAV body and propeller blades, which is not conducive to miniaturization.

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the following will be described clearly and completely in combination with the technical solution in the embodiments of the utility model. Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0027] A preferred embodiment of the utility model is a drone propeller retracting device and a helipad; Figure 1 and Figure 8 As shown, it includes a parking apron 11 for parking a drone 10, a rear centering device 13 is provided on the apron, and the drone is centered by the centering device. The apron is surrounded by blade retracting devices 12, and the blades of the drone after centering are adjusted by the blade retracting devices to reduce the size of the apron. The apron is also provided with a charging device 14 for charging the drone, and an expansion interface 16 for expanding the functions of the apron.

[0028] Specifically, Figure 1-3As shown, the paddle-retracting device 12 includes a fixed bracket 120, and two groups of steering gears 121 connected to the fixed bracket. One end of the fixed bracket is connected to the apron, and the other end is connected to the steering gear so that the steering gear is fixed around the apron, and the two groups of steering gears on each group of fixed brackets are fixed side by side. The paddle-retracting device 121 also includes a driven column 122 connected to the steering gear, and the driven column is driven to rotate by the rotation of the steering gear. The driven column is connected to an electric push rod 123, one end of the electric push rod passes through the driven column and rotates with the driven column, and the other end is connected to a baffle 124, and the two sides of the baffle are connected by two groups of electric push rods. It should be noted that the two sets of servos move synchronously to make the electric push rods rotate synchronously in the same direction, and the rotation pushes the UAV blades to rotate and thus perform the propeller retraction operation. Moreover, due to the existence of the two sets of electric push rods and the baffles provided between them, the failure of the propeller retraction caused by the electric push rods pushing the UAV blades to rotate at too large an angle is avoided. Even if the UAV blades rotate at too large an angle, the other set of electric push rods will generate a blocking force on them and rotate them at a small angle to retract them.

[0029] Furthermore, if Figure 3 As shown, the servo 121 includes a servo bracket 1210, and a rotating device 1211 disposed in the servo bracket, a rotating shaft 1212 is disposed on the rotating device, and the rotating device drives the rotating shaft to rotate, and the servo is connected and fixed to the fixed bracket 120 through the servo bracket. The servo also includes a steering wheel 1212 disposed on the rotating shaft, and a driven column 122 is connected to the steering wheel and rotates with the rotation of the steering wheel, so as to realize the rotation of the electric push rod driven by the rotating device. The electric push rod 123 includes a rotating rod 1240 and a telescopic rod 1241, one end of the rotating rod is inserted into the driven column 122 and rotates with the driven column, the telescopic rod is inserted into the rotating rod and can change its extended length, and a baffle is disposed at the end of the telescopic rod, thereby changing the rotation radius of the baffle to adapt to the blade retracting work of drones of different sizes. It should be noted that the two groups of electric push rods in the utility model rotate synchronously, so the size of the baffle does not change. It can also be set to rotate asynchronously. At this time, the baffle can be set to an openable and retractable state, and the baffle can be retracted by a conventional retracting method. This content can adopt the existing technology, so only a brief explanation is given here.

[0030] Furthermore, if Figure 4As shown, the centering device 13 includes four groups of centering components, two of which are placed in the same horizontal direction to form X-axis centering components, and the other two groups of centering components are placed in the same vertical direction to form Y-axis centering components. The X-axis centering component and the Y-axis centering component are perpendicular to each other, and the midpoints are arranged to coincide. The centering component includes a horizontal support block 131 and a vertical connection block 134, and the centering component is fixed to the lower end of the apron. The centering component also includes a motor 130 and a sliding guide rail 132 connected to the motor. A centering block 133 is provided on the sliding guide rail. The upper end of the centering block passes through the apron and is placed on the upper surface of the apron. The motor drives the movement of the centering block on the sliding guide rail, thereby realizing the movement of the centering block for centering. The four groups of centering components can move independently of each other or can be combined in series.

[0031] Furthermore, if Figure 5 As shown, the charging device 14 includes a fixed column 141, and a charging electrode 140 arranged above the fixed column, and the charging electrode is used to charge the drone. The charging device can be fixedly set at the upper end of the apron, or it can be movably set at the upper end of the apron. When it is fixedly set at the upper end of the apron, it is necessary to drive the drone to move to the charging device for charging through the centering block. When it is movably set at the upper end of the apron, it is preferably set above the sliding track of the X-axis centering component or the Y-axis centering component. At this time, the drone can be centered first and then the charging pile can be moved to the vicinity of the drone to charge the drone. The charging device 14 also includes two sets of stop walls 142, which are arranged in a long strip shape. The long strip stop walls prevent drones of different models from being unable to contact the charging device when they move near the Chongnian device. Due to the presence of the long strip stop wall, it is guaranteed to contact the drone for charging.

[0032] Furthermore, if Figure 6-7 As shown, the apron 11 includes an aluminum profile 110, and a panel 111 arranged on the upper surface of the aluminum profile. Every two groups of panels are connected by a connecting plate 112, and a sliding groove 113 is arranged between the connecting plate and the panel. The connecting arm of the centering device slides in the sliding groove to keep the centering block moving synchronously. A fixing seat 114 is arranged around the aluminum profile, and the apron is fixed to the parking rack through the fixing seat. The aluminum profile 110 includes an outer frame profile 1103, and a vertical profile 1100 and a horizontal profile 1101 arranged in the outer frame profile. The centering device is placed below the vertical profile and the horizontal profile, and the sliding groove is above both sides of the vertical groove and the horizontal groove. In order to avoid drilling holes in the aluminum profile, multiple grooves are arranged on the aluminum profile, and one end of the screw can be fixed by passing through the groove to avoid drilling holes in the screw.

[0033] Furthermore, if Figure 8 As shown, an extended power supply 17 and a drive module 18 are also provided at the bottom of the apron 11 to increase the charging endurance of the apron for the drone and improve the functionality of the apron.
