Description

A multi-rotor UAV shock-absorbing landing gear

technical field

The utility model relates to a shock-absorbing landing gear of a multi-rotor unmanned aerial vehicle, which belongs to the field of aircraft innovation technology.

Background technique

As a new type of aircraft, UAV is widely used in military and civilian fields because of its small size, easy operation, low cost, and easy completion of special tasks. The multi-rotor UAV has become a very popular UAV model due to its advantages of vertical take-off and landing, easy hovering, and high stability. However, due to the influence of the weather, multi-rotor drones are very challenging to operate when flying, and they are more prone to crashes and unstable landings during the operation process. During this process, the landing gear plays a great role in protection. Most commonly used landing gears do not have shock-absorbing devices, or use generally flexible materials for shock-absorbing, and the shock-absorbing effect is not good.

Contents of the invention

The purpose of the utility model is to provide a multi-rotor UAV shock-absorbing landing gear to solve the problem of poor shock-absorbing effect of the landing gear during the landing protection process of the multi-rotor UAV.

Connecting bolt I14, connecting bolt II15; the mounting frame 10 is installed at the lower part of the landing frame 2, one end of the positioning frame 9 and the shock absorber 11 are installed on the mounting frame 10 through the connecting bolt I14, and the supporting connecting frame 13 is connected through the connecting bolt II 15 is installed on the other end of the positioning frame 9 and the shock absorbing frame 11, the supporting frame 12 is installed on the lower part of the supporting connecting frame 13, one end of the shock absorbing device 8 is installed on the shock absorbing frame 11, and the other end is installed under the landing connecting frame 2, and the shock absorbing The device 8 includes a mounting base I17, a spring shock absorber 18, a mounting base II19, and a connecting bolt III20; the mounting base I17 is installed on the shock absorber 11, the mounting base II19 is installed under the landing joint 2, and one end of the spring shock absorber 18 passes through The connecting bolt III20 is installed on the mounting base I17, and the other end is installed on the mounting base II19 through the connecting bolt III20.

Described right undercarriage 7 structure is identical with left undercarriage 6.

A circular installation hole 16 is provided in the middle part of the landing connector 2 for installing the drone onboard camera.

The working principle of a multi-rotor UAV shock-absorbing landing gear is: the landing gear is composed of a left landing gear 6 and a right landing gear 7. When the UAV lands, the support frame 12 lands first. Due to the weight of the aircraft itself or Landing instability and other reasons will produce downward gravity. At this time, the mounting frame 10 and the positioning frame 9 rotate slightly around the connection parts at both ends, and the spring shock absorber 18 is compressed by force. After the power is consumed, the spring shock absorber 18 Under the action of elastic force, the UAV is kept in a stable state to achieve a good shock absorption effect.

The utility model has the following beneficial effects:

1. The principle of spring shock absorption is adopted, which has a good protection effect on drones;

2. The structure is reasonable, the use effect is remarkable, and it has high promotion value.
