DETAILED DESCRIPTION
[0022] 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. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] See also Figure 1-6 , an embodiment provided by the utility model:
[0024] A drone support adjustment mechanism includes a drone chassis 1, characterized in that: a fixed block 2 is fixedly connected to the surface of the drone chassis 1, a first bracket 21 is rotatably connected to the surface of the fixed block 2, a second bracket 22 is rotatably connected to the surface of the fixed block 2, a dislocation block 23 is fixedly connected to the surface of the first bracket 21, a first connecting plate 24 is rotatably connected to the surface of the dislocation block 23, a cylinder 25 is fixedly connected to the surface of the first connecting plate 24, a second connecting plate 26 is fixedly connected to the piston rod of the cylinder 25, and the second connecting plate 26 is rotatably connected to the surface of the second bracket 22, a support rod 27 is provided on the lower surface of the drone chassis 1, a storage groove 28 is fixedly connected to the lower surface of the drone chassis 1, and the drone chassis 1 A limiting mechanism is provided at the bottom, and the limiting mechanism includes a bolt 3, which is threadedly connected to the bottom of the drone chassis 1, and a mounting plate 31 is perforated on the surface of the bolt 3, and a limiting block 32 is fixedly connected to the surface of the mounting plate 31, and a slope 33 is provided on the surface of the limiting block 32. The drone bracket adjustment mechanism can adjust the angle of the first bracket 21 and the second bracket 22 at the bottom of the drone chassis 1, so that the first bracket 21 and the second bracket 22 are folded at the bottom of the drone chassis 1 to reduce the wind resistance of the drone. At the same time, the limiting mechanism can ensure the rotation position of the first bracket 21 and the second bracket 22 at the bottom of the drone chassis 1, and ensure that the first bracket 21 and the second bracket 22 can stably support the drone.
[0025] Furthermore, the fixing block 2 is provided with four groups, the first bracket 21 and the second bracket 22 are provided with two groups each, the first bracket 21 and the second bracket 22 are rotated at the bottom of the UAV chassis 1 through the fixing block 2, and the first bracket 21 and the second bracket 22 rotate in opposite directions at the bottom of the UAV chassis 1. After the first bracket 21 and the second bracket 22 are rotated to a certain angle, the UAV chassis 1 is supported.
[0026] Furthermore, the cylinder 25 rotates on the surface of the offset block 23 through the first connecting plate 24, so that the cylinder 25 rotates on the first bracket 21, and the cylinder 25 rotates on the surface of the second bracket 22 through the second connecting plate 26. When the piston rod of the cylinder 25 is extended or retracted, the cylinder 25 can rotate on the first bracket 21 and the second bracket 22 at the same time, and the height of the cylinder 25 will also change accordingly.
[0027] Furthermore, the offset block 23 and the second bracket 22 are on the same horizontal line, and the offset block 23 offsets the positions of the first bracket 21 and the second bracket 22, so that the first bracket 21 and the second bracket 22 are not on the same level. The first bracket 21 and the second bracket 22 will not touch each other when rotating at the bottom of the drone chassis 1, and sufficient folding space is reserved for the first bracket 21 and the second bracket 22 at the bottom of the drone chassis 1, thereby improving space utilization.
[0028] Furthermore, two groups of support rods 27 are provided and are parallel to each other, and four groups of storage grooves 28 are provided. The storage grooves 28 can be used as temporary supports for the UAV chassis 1. The cylinder 25 is located directly below the support rod 27. When the piston rod of the cylinder 25 is fully retracted inside the cylinder 25, the height of the cylinder 25 is at the highest point. At this time, the cylinder 25 is on the support rod 27. The support rod 27 is a space reserved for the cylinder 25 to prevent the cylinder 25 from blocking the first bracket 21 and the second bracket 22 from folding at the bottom of the UAV chassis 1.
[0029] Furthermore, a threaded groove is provided at the bottom of the UAV chassis 1, and the bolt 3 is threadedly connected to the threaded groove at the bottom of the UAV chassis 1. A circular hole is provided on the surface of the mounting plate 31, and the bolt 3 passes through the circular hole of the mounting plate 31. The bolt 3 fixes the limit block 32 to the bottom of the UAV chassis 1 through the mounting plate 31.
[0030] Furthermore, the limit block 32 is trapezoidal in shape, and the first bracket 21 and the second bracket 22 are in contact on the inclined surface 33 by rotation. The limit block 32 limits the rotation angle of the first bracket 21 and the second bracket 22, so that the rotation angles of the first bracket 21 and the second bracket 22 are the same, thereby ensuring the stability of the first bracket 21 and the second bracket 22 in supporting the drone chassis 1.
[0031] Working principle: The second connecting plate 26 is driven to move by the piston rod of the cylinder 25. During the movement, the second connecting plate 26 will drive the second bracket 22 to rotate at the bottom of the drone chassis 1. The second bracket 22 rotates on the second connecting plate 26 at the same time. The cylinder 25 will drive the first bracket 21 to rotate at the top of the drone chassis 1 through the offset block 23. At the same time, the offset block 23 will rotate on the cylinder 25 through the first connecting plate 24. The first bracket 21 and the second bracket 22 will drive the cylinder 25 to rise and fall during the rotation. The cylinder 25 can be stored on the support rod 27. The first bracket 21 and the second bracket 22 adjust their angles at the bottom of the drone chassis 1 during the rotation, so that the first bracket 21 and the second bracket 22 can be folded and stored at the bottom of the drone chassis 1 to reduce the wind resistance of the drone.
[0032] The bolt 3 is passed through the circular hole of the mounting plate 31, and the bolt 3 is threadedly connected to the threaded hole at the bottom of the UAV chassis 1. The bolt 3 fixes the limit block 32 to the bottom of the UAV chassis 1 through the mounting plate 31. The first bracket 21 and the second bracket 22 will contact the inclined surface 33 on the limit block 32 during the rotation of the bottom of the UAV chassis 1. The limit block 32 limits the rotation angle of the first bracket 21 and the second bracket 22, thereby ensuring the stability of the first bracket 21 and the second bracket 22 in supporting the UAV.
