Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicles, in particular to a wing folding mechanism for a mother-and-child mounted unmanned aerial vehicle. Background Art

[0002] There are a large number of overhead bare wires in the power distribution lines, which often pass through woods, waters, high-rise buildings and densely populated areas. It is very easy to cause accidents such as accidental electric shock, bird nest grounding tripping, and tree short circuit fire. Therefore, drones are usually used to clean up the power grid;

[0003] The existing technology is in the form of separating the transport tool and the operating robot into two entities, which increases the operation, manpower and maintenance costs of the entire project. The existing technology requires the use of a drone to lift the robot up, and then the drone is offline. After the robot's operation is completed, the drone must be launched again to pick up the robot, which is very troublesome and reduces the operational difficulty and inconvenience of maintaining the power distribution lines. Utility Model Content

[0004] The purpose of the utility model is to provide a wing folding mechanism for a mother-and-child mounted UAV to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a mother-and-child type mounted UAV wing folding mechanism, comprising a mounting shell, grooves are provided on both sides of the mounting shell, and main wing support arms are hinged on the inner sides of the grooves, a motor is provided at the bottom of the interior of the mounting shell, a screw rod is sleeved inside the motor, a main wing connecting ring is provided on the top of the screw rod, main wings are sleeved on both sides of the main wing connecting ring, and two groups of main wings and two groups of main wing support arms are hinged to each other.

[0006] Preferably, the main wing connecting ring is made of an H-shaped structure, and the two groups of main wings are movably arranged on the inner side of the H-shaped main wing connecting ring. The H-shaped structure is used to drive the linkage adjustment of the main wings to improve the stability of the main wing folding.

[0007] Preferably, hinge blocks are installed at the bottom of the two groups of main wings, and the hinge blocks are movably connected to the main wing support arms, so as to improve the limiting effect of the main wing folding through the movable limiting of the hinge blocks and the main wing support arms.

[0008] Preferably, multiple groups of through grooves are provided on the outer sides of the two groups of main wing support arms and the main wing, so that the main wing support arms and the main wing are provided with through groove structures, thereby reducing the weight of the drone components.

[0009] Preferably, the motor is a through-type linear screw motor, and the screw is telescopically movable inside the motor, so as to facilitate the screw to be driven to be adjusted vertically, and the screw drives the lifting and lowering control of the main wing connecting ring.

[0010] Preferably, through holes are provided at the top and the bottom of the installation shell, and the screw rod is telescopically movable inside the through hole, so that the screw rod is adjusted to rise and fall under the control of the motor in the installation shell.

[0011] The utility model proposes a wing folding mechanism for a mother-and-child mounted UAV, which at least comprises the following:

[0012] Beneficial effects:

[0013] This is achieved through the folding of the wingspan. When the drone is working, the two main wings are spread out to the horizontal. When it reaches the designated location and stops working, the outer ends of the two main wings are folded inward and downward to lower the center of gravity of the entire machine, so that the height of the center of gravity is lower than the height of the cable, which is beneficial to the movement of the operating robot on the cable and improves the stability of the robot's movement during operation. The design of this structure makes the drone and the unmanned operating robot become a whole. The drone will not hinder the robot's operation and can also provide the robot with the movement required to go up and down the cable at any time, thereby improving the simplicity and work efficiency of the drone in the power distribution cable of the power grid.

[0019] 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.

[0020] See also Figure 1-4The utility model provides an embodiment: a mother-and-child type mounted UAV wing folding mechanism, comprising a mounting shell 1, grooves are provided on both sides of the mounting shell 1, and main wing support arms 4 are hingedly connected to the inner sides of the grooves, a motor 6 is provided at the bottom inside the mounting shell 1, a screw rod 5 is sleeved inside the motor 6, a main wing connecting ring 3 is provided at the top of the screw rod 5, main wings 2 are sleeved on both sides of the main wing connecting ring 3, and two groups of main wings 2 and two groups of main wing support arms 4 are hinged to each other, through holes are provided at the top and bottom of the mounting shell 1, and the screw rod 5 is telescopically moved inside the through hole, so that the screw rod is adjusted and lifted under the control of the motor 6 in the mounting shell 1, so as to facilitate the screw rod 5 to be vertically lifted and adjusted, and the screw rod 5 drives the lifting and lowering control of the main wing connecting ring 3.

[0021] Embodiment 1, as Figure 1-4 As shown, the main wing connecting ring 3 is made of an H-shaped structure, and the two groups of main wings 2 are movably arranged on the inner side of the H-shaped main wing connecting ring 3. A hinge block is installed at the bottom of the two groups of main wings 2, and the hinge block is movably connected to the main wing support arm 4. The main wing 2 and the main wing support arm 4 are movably connected as an integrated whole through the main wing connecting ring 3 of the H-shaped structure, so that when the main wing connecting ring 3 rises, the main wing 2 is driven to fold downward and inward under the movable limit of the main wing support arm 4, so that when the main wing 2 is folded, the center of gravity of the entire machine is lowered, which is beneficial to the movement of the working robot on the cable.

[0022] Embodiment 2, as Figure 1-4 As shown, two sets of main wing support arms 4 and the outer sides of the main wings 2 are provided with multiple sets of through grooves. By evenly providing the through grooves, the weight of the main wing material of the UAV is reduced and the wind and air flow are guided, thereby making the flight of the UAV more stable.

[0023] Working principle: In the wing folding mechanism of the mother-and-child mounted drone;

[0024] When the drone is in use, the motor 6 is started to drive the lead screw 5 to rise vertically, prompting the lead screw 5 to drive the main wing connecting ring 3 to move upward and push the inner end of the main wing 2 upward. When the inner end of the main wing 2 is pushed upward, the outer end moves downward and inward, thereby raising the main wing connecting ring 3 and synchronously driving the movably connected main wing 2 and the main wing support arm 4 structure to be linked. At this time, the outer ends of the two sets of main wings 2 on both sides can be folded inward and downward to lower the center of gravity of the entire machine, so that the height of the center of gravity is lower than the height of the cable, which is beneficial to the movement of the operating robot on the cable and improves the stability of the robot's movement during operation. By folding the main wing 2, the drone and the unmanned operating robot become a whole. The drone will not hinder the robot's operation and can also provide the robot with the movement required for the up and down cables at any time.
