Detailed implementation manners

[0029] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the drawings and embodiments.

[0030] Embodiment 1

[0031] In this embodiment, as shown in Figures 1-6As shown in the figure, a balance detection device for an unmanned aerial vehicle (UAV) flight control system includes a bottom plate 101. An annular groove and a toothed ring are provided on the side wall of the bottom plate 101. The annular groove is arranged on the upper and lower sides of the toothed ring. A slider 102 is slidably arranged inside the annular groove. A roller may be provided at the lower end of the slider 102. A first gear 103 meshing with the toothed ring is arranged inside the slider 102. One end of the gear shaft of the first gear 103 extends outside the slider 102 and is fixedly connected to the output end of a first motor. When the first motor is started to drive the first gear 103 to rotate, due to the limiting effect of the annular groove, the slider 102 drives the fixed column 301 to make a circular motion around the bottom plate 101, so as to simulate the influence of blowing in different directions on the flight state of the UAV. A support column 104 is fixedly installed at the upper end of the bottom plate 101. A lifting assembly is arranged inside the support column 104 to facilitate adjusting the position height of the UAV to adapt to the airflow in different directions. The top of the lifting assembly is fixedly connected to a tray 105. Scale lines or partitions are provided above the tray 105 to facilitate placing the UAV at the center position of the tray 105. It also includes a detection mechanism 200 and a blowing mechanism 300. The detection mechanism 200 is arranged outside the tray 105 and is used to detect the balance of the UAV's several wings during flight. The blowing mechanism 300 is arranged at the upper end of the slider 102 and is used to simulate blowing in different directions;

[0032] The lifting assembly includes a moving groove opened inside the support column 104. A moving column 106 is slidably arranged inside the moving groove. A plurality of racks are arranged on one side of the moving column 106. A second gear 107 is meshed on one side of the racks. The second gear 107 is rotatably connected to the inner wall of the moving groove. One end of the gear shaft of the second gear 107 extends outside the support column 104 and is fixedly connected to the output end of a second motor. When the second motor is started to drive the second gear 107 to rotate, the moving column 106 is driven to move up and down.

[0033] Among them, such as Figures 2-6As shown, the detection mechanism 200 includes a plurality of sliding grooves 201 formed in the side wall of the tray 105. A support arm 202 is slidably arranged inside the sliding groove 201. The support arm 202 is fixedly connected to the tray 105 by a plurality of screws, which is convenient for adapting to the wings of unmanned aerial vehicles (UAVs) with different specifications and sizes, and for adjusting the position of the support arm 202 according to the angle between the wings of the UAV. A groove 203 is formed on the upper surface of the support arm 202. A movable block is slidably arranged inside the groove 203. The movable block is fixedly connected to the support arm 202 by a bolt, which is convenient for adjusting the position of the suction cup 207 and for adapting to the wings of the UAV. A cylinder 204 is fixedly installed at the lower end of the support arm 202. A pressure gauge 205 is arranged on one side of the cylinder 204. A piston 206 is slidably arranged inside the cylinder 204. The piston 206 is made of a material with good airtightness. A spring is arranged between the piston 206 and the inner wall of the cylinder 204. When the wings of the UAV are started, the suction cup 207 drives the pulling rope to move, thereby driving the piston 206 to move, causing the internal pressure of the cylinder 204 to drop. The internal pressure of the cylinder 204 can be detected by the pressure gauge 205. By observing the stability of the UAV and the pressure value of the pressure gauge 205, the balance state of the UAV during flight can be determined. When there is an obvious tilt or a large difference in the pressure value of the pressure gauge 205, it indicates that the UAV is unbalanced during flight control.

[0034] As shown in Figure 2 and Figure 4 As shown, the air supply mechanism 300 includes a fixed column 301 fixedly connected to the slider 102. A disc 302 is rotatably arranged at the top of the fixed column 301. A fan 303 is fixedly installed on one side of the disc 302 close to the tray 105. The wind force of the fan 303 is used to simulate the airflow conditions in different directions. One end of the rotating shaft of the disc 302 extends to the outside of the fixed column 301 and is fixedly connected to a turntable 304. The turntable 304 is fixedly connected to the fixed column 301 by a plurality of bolts, which is convenient for adjusting the rotation direction of the fan 303 and for fixing the position of the fan 303.

[0035] As shown in Figure 1 As shown, support members 108 are symmetrically arranged at the lower end of the bottom plate 101. The support members 108 can be set as bases or rollers, which play a supporting role and are convenient for movement.

[0036] As shown in Figure 1 and Figure 2 As shown, a plurality of arc-shaped grooves 109 are symmetrically formed on the upper surface of the bottom plate 101. A telescopic rod 110 is slidably arranged inside the arc-shaped groove 109. The telescopic rod 110 moves as the moving column 106 moves up and down. The telescopic end of the telescopic rod 110 is fixedly connected to the lower surface of the cylinder 204. The number of the arc-shaped grooves 109 is the same as that of the sliding grooves 201, which plays a supporting role for the support arm 202 and further increases the overall practicality of the device.

[0037] Among them, as Figure 5 shown, suction cups 207 are provided above several support arms 202. A limiting ring is provided at the upper end of the movable block. The suction cups 207 are arranged on one side of the limiting ring close to the tray 105. One end of the pull rope passes through the limiting ring, then through the guiding ring 208 and is connected to the piston 206. The suction cups 207 and the piston 206 are connected by the pull rope. The pull rope is made of materials with the same material, tensile coefficient, and specification size to reduce errors.

[0038] Among them, as Figure 4 shown, guiding rings 208 are fixedly connected to both the upper and lower sides of the support arm 202. The pull rope is arranged inside the guiding ring 208 to prevent the pull rope from shifting, resulting in a large difference in the pressure situation.

[0039] Embodiment 2

[0040] Different from Embodiment 1, among them, as Figure 7 and Figure 8 shown, rounded corners are provided on the side of the support arm 202 away from the tray 105. A pull rope groove is provided on one side of the rounded corner. The pull rope is slidably connected to the pull rope groove to prevent the pull rope from rubbing against the support arm 202 when moving, resulting in damage to the pull rope.

[0041] During use, first place the drone in the middle position of the tray 105. After adjusting the support arms 202 to the corresponding positions according to the drone wings, adsorb the suction cups 207 under the drone wings so that the adsorption positions between several suction cups 207 and the drone wings are consistent. When the drone wings are started, the drone drives the suction cups 207 to rise, thereby stretching the pull rope to move, driving the piston 206 to move, causing the pressure inside the cylinder 204 to drop. The pressure inside the cylinder 204 can be detected by the pressure gauge 205, which is convenient for determining the balance state of the drone during flight. Before starting the drone wings, adjust the height of the tray 105 and the rotation direction of the fan 303 for convenient multiple experimental operations.

[0042] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
