AI Technical Summary
The existing electric cylinders cannot return to the normal opening state of the brake when power is off, resulting in the inability to achieve long-term braking in the event of power off.
A new type of energy storage electric cylinder is designed, including a motor, reducer, ball screw, energy storage spring and push rod. The ball screw is driven by the motor to rotate and compress the energy storage spring, so that the push rod can retract the energy storage, and when the motor is broken After power, the spring's non-locking function is used to push the push rod out to achieve a long-term normal opening state of the brake and return to position itself in any state.
It realizes that the electric cylinder can return to the normal opening state of the brake by itself when the power is off, ensuring that the brake can maintain a long-term braking effect in any state, and improving the reliability and convenience of the electric cylinder.
