Electric actuator and assembly with dual functions of strain sensing and damping mechanism thereof

An electric actuator, comprising:

• a gear box;
• a motor, connected to the gear box;
• a transmission mechanism, connected to the gear box and disposed at one lateral side of the motor, wherein the transmission mechanism is driven by the motor;
• and
• an assembly with dual functions of strain sensing and damping mechanism, disposed at one side of the gear box opposite to the transmission mechanism and comprising a load body, a pair of strain sheets, a cable connector and an impact absorbing unit, wherein the load body comprises a columnar member and a flange extended from the columnar body, the columnar member comprises an opening, and a pair of detected surfaces is disposed on two sides of the opening opposite to each other;
• the pair of strain sheets is attached on the pair of detected surfaces to sense a deforming level of the pair of detected surfaces;
• the cable connector comprises a connection head and a cable, the connection head is connected to the columnar member, and the cable passes the connection head to be electrically connected to each of the strain sheets;
• the impact absorbing unit is disposed on one end surface of the flange to absorb an impact force applied to the load body.
