A1

Disclosed in the present application is an electric push rod. The electric push rod comprises a pressure compensation part, a driving part, and a pushing part; the pressure compensation part has one end connected to an external power source and the other end electrically connected to the driving part; the driving part is connected to the pushing part; and the interior of the pressure compensation part is communicated with the interior of the driving part to form a sealed area that is filled with an insulation liquid for performing pressure compensation on the electric push rod. Furthermore, a casing of the electric push rod is used as a motor housing of a driving motor of the driving part. In the present application, a pressure compensation structure is additionally provided on the electric push rod, such that the electric push rod itself has a pressure compensation function, without needing to additionally provide an auxiliary pressure compensator, thereby reducing the system size and allowing for usage in a deep sea environment.
