Object of the present invention can be achieved through the following technical solutions:
A kind of power assembly active vibration isolation element, comprise the first connecting bolt, expanded film, housing, rubber spring, inertia channel body, decoupling zero film, micro electromagnetic actuator and the second connecting bolt, described the first connecting bolt bottom is embedded in rubber spring top, described rubber spring outside is provided with housing, one end of expanded film is connected with the sulfuration of rubber spring top, the other end is fixed on housing middle part, described rubber spring bottom side is provided with decoupling zero film, and described decoupling zero film is connected with the output shaft sulfuration of micro electromagnetic actuator.
Described housing has upper shell and lower shell body, and one end of described upper shell is connected with the sulfuration of outside, rubber spring upper end, and the other end of upper shell and the upper end of lower shell body form throttle orifice.
The bottom of described lower shell body is the draw-in groove portion forming to the inside, and the bottom sides that described draw-in groove portion accommodates rubber spring from top to bottom is successively along the end of extension part, decoupling zero film, the transverse part of supporting component.
Described supporting component has the bending part with transverse part homonymy, and described bending part is fixed by the second connecting bolt.
Described rubber spring bottom outside is provided with inertia channel body.
Described rubber spring top is conical, and bottom has circular cylindrical cavity.
