The invention relates to a range extender unit and a range extender module for a vehicle. The range extender unit includes: a motor; a torsional vibration damper (10) which is coaxially arranged on the radial inner side of the electric machine, one end (12) of the torsional vibration damper (10) being connected to a rotor (9) of the electric machine in a rotationally fixed manner; a housing (1) surrounding the electric machine and the torsion damper (10); and a transmission shaft (15) which is arranged coaxially on the radial inner side of the torsion damper (10), the transmission shaft (15) being connected in a rotationally fixed manner to the other end (11) of the torsion damper (10), and an axial end of the transmission shaft (15) extending out of the housing (1), said axial end being formed with a face spline (17). The range extender module comprises a controller and the range extender unit.

The utility model relates to a three-way hydraulic lock device which structurally comprises a lock body, a fusiform piston and a one-way valve. Two fusiform pistons are connected in the lock body in a sliding mode, and trigger rods are arranged at the outer ends of the fusiform pistons and make contact with the opening portion of an inlet of the one-way valve to control the one-way valve to be opened; the inner end part of the fusiform piston is a circular truncated cone or a cylinder with a reduced diameter, the end surfaces of the circular truncated cone or the cylinder are in contact fit, and an inner cavity is formed in the middle of the lock body; the lock body is provided with six oil inlet and outlet holes, namely a hole A, a hole B, a hole C, a hole D, a hole E and a hole F; and the six oil inlet and outlet holes are divided into three groups and are respectively communicated with the left, middle and right inner cavities of the lock body. The three-way hydraulic lock device meets the locking requirement of the single-cylinder-body double-stroke oil cylinder in the stroke range, and is small in size and high in stability.
