[0033] The motor 2, the electric push rod 3, and the spring pull rod 7 are arranged on the push rod seat 1, and one end of the electric push rod 3 is connected to the motor 2, and the other end is connected to the spring pull rod 7;

[0034] One end of the rocker arm 8 is connected to the end of the spring pull rod 7 that is not connected to the electric push rod 3, and the other end of the rocker arm 8 is connected to the locking block 10 to form a multi-link mechanism. The locking block 10 is driven to perform locking and unlocking operations through the rotation of the rocker arm 8.

[0035] Working principle: This embodiment is installed on the launch frame in the launch box through the push rod seat 1. The motor 2, electric push rod 3, and spring pull rod 7 are installed on the push rod seat 1 as a component. The two ends of the rocker 8 are respectively connected to the spring pull rod 7 and the locking block 10 to form a multi-link mechanism. When the motor 2 rotates forward and reverse, it drives the electric push rod 3 to perform telescopic movement, and then drives the spring pull rod 7 to rotate the rocker 8. The upper end of the rocker 8 drives the locking block 10 to perform locking and unlocking movements. The automatic locking mechanism of the launch box realizes the function of automatically completing the locking and unlocking of the drone after receiving instructions during the launch and transportation of the drone. This automatic locking mechanism of the launch box has a small size, simple structure, high reliability, and convenient maintenance. After installation, it can ensure the safe transportation and launch of the drone in the launch box.

[0036] Embodiment 2:

[0037] This embodiment is based on the above embodiment 1. Figure 2 As shown, the automatic locking mechanism of the UAV launch box also includes a collision block 6, a travel switch 4, and a travel switch mounting seat 5;

[0038] The collision block 6 is fixedly arranged on the electric push rod 3;

[0045] The notch 13 includes a locking notch and an unlocking notch;

[0046] When the travel switch 11 is separated from the locking notch, the locking switch sends a signal; when the travel switch 11 is separated from the unlocking notch, the unlocking switch sends a signal.

[0047] Working principle: In this embodiment, a collision block 6 is fixed on the electric push rod 3, and moves with the electric push rod 3. When the collision block 6 moves and hits the travel switch, the travel switch 4 sends a signal. The travel switch 4 is fixed to the motor 2 through the travel switch mounting base 5. The travel switch mounting base 5 is fixed with screws. The position of the travel switch 4 is adjustable. By adjusting the position of the travel switch 4, the travel of the electric push rod 3 can be controlled, and then the locking force of the locking mechanism can be controlled.
