Claims

1. A large angle flipping device for a drone, characterized by: It includes a support frame and a tilting mechanism and a winch mechanism respectively mounted on the support frame. The support frame is welded together from multiple structural components. Near one end of the support frame, there is a pulley that works with the winch mechanism. The flipping mechanism includes two bearing seats mounted on a support frame. Each bearing seat is fitted with a bearing. A lower clamp that can rotate freely along the radial direction of the bearing is clamped inside the two bearings. An upper clamp is provided above the lower clamp. The space between the upper and lower clamps is used to place the drone's nose. The connection between the upper and lower clamps is fixed by a tight-fitting handle. Limit blocks and support arms are respectively fitted and fixed to the outer sides of the two bearings. The end of the support arm is provided with a support groove for supporting the drone's wings. An elastic screw mechanism is also provided at the end of the bearing seat. When the upper and lower clamps holding the drone's nose are flipped more than 90 degrees, the limit block controls the flipping angle by contacting the elastic screw mechanism. The winch mechanism includes a winch mounted on a support frame, a steel wire rope extending from the winch passing through a pulley and connected to a D-type shackle, and the D-type shackle being connected to a lifting lug on the drone by an eye bolt.

2. The drone large angle flipping device of claim 1, wherein: The support frame is equipped with a polyurethane anti-collision foam board near the pulleys; four shock-absorbing casters for braking are provided around the bottom of the support frame; and a handle and a support base for supporting the tail of the drone are provided near the other end of the support frame.

3. The drone large angle flipping device of claim 1, wherein: Polyurethane rubber pads are provided at the contact points between the upper and lower clamps and the drone's nose, and at the contact points between the support groove and the drone's wing in the flipping mechanism.

4. The drone large angle flipping device of claim 1, wherein: The elastic screw mechanism includes a support platform, inside which a screw that can move freely up and down is threaded. A buffer spring is sleeved on the screw above the support platform, and a positioning nut is provided on the screw below the support platform. When the drone nose flips more than 90 degrees, the limit block contacts the screw, causing it to move downwards and compress the buffer spring. After the drone nose flips to the correct angle, the flip angle is positioned by tightening the positioning nut.

5. The drone large angle flipping device of claim 1, wherein: The winch uses a worm gear winch, which pulls the drone's nose to rotate around the bearing and flip it at a certain angle.
