[0002] A drone is an aircraft that can complete flight missions autonomously without human piloting. It is widely used in civil, military, scientific, logistics and other fields. Drones have the characteristics of small size, low cost and flexible flight.

[0003] With the continuous development of the logistics industry and the emergence of humanized needs, the traditional logistics model has been unable to meet the needs of the market, and more intelligent and comprehensive logistics solutions are needed. Drones, as a new tool in the logistics industry, can bring more opportunities to the industry.

[0004] However, current drones mostly transport goods through external pods, so personnel are required to place and receive the goods, which is not very convenient and efficient. Therefore, there is a need for a drone that can automatically grab and place goods. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this application is to provide a long-range and load-bearing grabbing and clamping logistics drone.

[0008] By adopting the above technical solution, a camera, a gripping device and a landing gear are installed on the lower shell of the drone. The drone can be controlled by a mobile phone or computer to grab the cargo to be transported through the gripping device and then transport it to the destination. The gripping device replaces the pod, so there is no need for personnel to place the cargo on the pod, and the operation is very convenient.

[0010] By adopting the above technical solution, external frames are respectively arranged on the left and right sides of the clamp, so that the friction between the drone and the goods can be increased when clamping the goods, making the clamping effect more stable and preventing the goods from falling accidentally.

[0011] A further optimization scheme, the grasping and clamping device also includes a driving assembly installed inside the clamp, the driving assembly includes a driving motor and a first partition, a second partition and a third partition fixedly connected to the inner wall of the clamp, and a gap is left between the first partition, the second partition and the third partition, the driving motor is fixedly connected to the lower object, and a driving gear is installed on the output shaft between the first partition and the second partition, the driving gear is meshingly connected with the first driven gear, the second driven gear is installed at the lower axis of the first driven gear, the upper and lower ends of the first driven gear and the second driven gear are installed with a rotating shaft and are rotatably connected with the first partition and the third partition, the second driven gear is meshingly connected with the third driven gear installed on the screw, the fourth driven gear is installed on the screw below the third driven gear, the fourth driven gear is meshingly connected with the fifth driven gear, the upper and lower ends of the fifth driven gear are installed with a rotating shaft and are rotatably connected with the second partition and the third partition.

[0012] By adopting the above technical solution, multiple sets of gear mechanisms are used inside the clamp, which can not only obtain a larger transmission ratio, but also the self-locking property between the multiple sets of gears, thereby preventing the goods from accidentally falling during the clamping or transportation process, thereby affecting the working efficiency of the drone.

[0014] By adopting the above technical solution and using a retractable landing gear, retracting the landing gear during flight can reduce air resistance and increase the endurance of the UAV, and extending the landing gear during landing can reduce the impact of the UAV and ensure a smooth landing.

[0015] As a further optimization solution, the upper shell is made of high-strength carbon fiber material.

[0016] By adopting the above technical solution, the upper shell is made of high-strength carbon fiber material, which can reduce the weight of the drone itself and increase the endurance of the drone.

[0017] According to a further optimization solution, a GPS antenna is installed at the upper end of the upper shell.

[0018] By adopting the above technical solution, a GPS antenna is installed on the upper end of the upper shell, which can receive signals more sensitively than when installed inside the drone.

[0020] By adopting the above technical solution, in order to increase the endurance of the drone, a solar panel is installed on the upper part of the outer shell of the drone. When the drone is working, the light energy is converted into electrical energy and stored in the battery, further increasing the endurance of the drone.

[0021] According to a further optimization scheme, a frame pad is installed at the lower part of the outer frame.

[0022] By adopting the above technical solution, the friction with the goods can be increased, and the clamping pad can prevent the goods from being damaged when clamping.
