Locking assembly for a linear actuator
By combining ball nuts and locking rotors with a spring system and solenoid control, an electric actuation locking mechanism for the linear actuator is achieved, solving the problems of bulkiness and complexity of hydraulic locking mechanisms. This provides an electric locking assembly with automatic locking and independent control, meeting the needs of electric aircraft platforms.

AI Technical Summary
The locking mechanisms of existing linear actuators typically employ bulky, expensive, and complex hydraulic devices that require frequent maintenance, making it difficult to meet the needs of electric aircraft platforms for electrically actuated locking mechanisms.
The locking assembly employs a combination of a ball nut and a locking rotor. The ball nut has a locking protrusion, and the locking rotor has a ridge-shaped protrusion. Locking and unlocking are achieved by aligning and misaligning the ridge-shaped protrusion with the locking protrusion. Combined with a spring system and solenoid control, automatic locking and independent control are realized.
A simple and reliable electrically actuated locking mechanism is provided, which can automatically lock in the absence of power, is independent of other parts of the system, prevents accidental deployment, reduces maintenance frequency, and meets the needs of electric aircraft platforms.
