Ejection-type unmanned aerial vehicle launching device

Abstract

The invention discloses an ejection-type unmanned aerial vehicle launching device. The device includes a base, a launching pad, a locking mechanism and a control device; the top of the base is provided with a spring perpendicular to the base, the top end of the spring is provided with the launching pad, the locking mechanism includes a first lock body, a second lock body, a lifting power plant andan electromagnetic control device, the lifting power plant is fixedly installed on the base, the first lock body is connected with the driving shaft of the lifting power plant, the bottom surface ofthe launching pad is provided with a square groove, a blind hole is formed in the side surface of the square groove, one end of the second lock body is hinged onto the launching pad, a spring reset part is placed in the blind hole, one end of the spring reset part is connected with the second lock body, one close ends of the first lock body and the second lock body are fixedly provided with a first lock block and a second lock block respectively, and the first lock body is provided with an electromagnetic control mechanism. The device has the advantages of simple structure and low use costs.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a catapult-type unmanned aerial vehicle launching device. Background technique [0002] At present, there are two main ways to take off small UAVs: hand-throwing and ejection. For the way of hand-throwing take-off, it is difficult to guarantee the normal attitude of the UAV when it takes off, and it is very easy to fail. The ejection methods are all vehicle-mounted or fixed, which is not convenient to carry and travel on the complex, and it is difficult to reach the most favorable launch location. There are great restrictions on the performance of the UAV. The mechanism has high reliability, low use cost, simple operation and can be recycled. In the past, the vehicle-mounted launch used the electric squib mechanism to unlock, but the unlocking mechanism has a high cost of use. The electric squib is a pyrotechnic product, which is expensive. There are strict req...

Problems solved by technology

For the way of hand-throwing take-off, it is difficult to guarantee the normal attitude of the UAV when it takes off, and it is very easy to fail

The ejection methods are all vehicle-mounted or fixed, which is not convenient to carry and travel on the complex, and it is difficult to reach the most favorable launch location. There are great restrictions on the performance of the UAV. The mechanism has high reliability, low cost of use, simple operation, and can be recycled

In the past, the vehicle-mounted launch used the electric squib mechanism to unlock, but the unlocking mechanism has a high cost of use. The electric squib is a pyrotechnic product, which is expensive. There are strict requirements for the purchase and transportation of the electric squib; It is a permanent product, it needs to be replaced once it is launched, and it cannot be recycled
