Specifically, the height of the auxiliary boss 126 is lower than the height of the mounting boss 121, which can avoid interference of the auxiliary boss 126 with the installation of the suspension bracket. At the same time, by providing the auxiliary boss 126, the overall structural strength of the suspension mounting seat 120 can be improved, and the bearing installation effect can be ensured.

[0044] Further, the first mounting platform 123, the second mounting platform 124, the third mounting platform 125 and the auxiliary boss 126 are arranged in a substantially parallelogram shape, wherein the first mounting platform 123 and the auxiliary boss 126 are located at the two side edges of the suspension mounting seat 120 and are farthest apart, the second mounting platform 124 is arranged close to the first mounting platform 123, and the third mounting platform 125 is arranged close to the auxiliary boss 126.

At the same time, since the motor housing 112 can be shortened, after the motor end cover 250 is installed, the axial size of the overall range extender 200 is shortened, which is beneficial to the miniaturization and light weight of the range extender 200.

[0048] In some embodiments, the rear end of the motor housing 112 is provided with a flange ring 114, which protrudes outward relative to the outer wall of the motor housing 112 and surrounds to form a port 113, and the flange ring 114 is provided with a plurality of assembly holes 115 and is used to fix the motor end cover 250.

[0049] For reference Figure 4 Further, the bottom side of the suspension mount 120 is also provided with an avoiding notch 127 corresponding to the assembly hole 115, which is used to avoid the edge of the motor end cover 250. Specifically, the avoiding notch 127 can expose the mounting lugs on the flange ring 114, which facilitates the lugs on the motor end cover 250 to be installed. Moreover, since the avoiding notch 127 is provided, the suspension mount 120 is not in the form of a flat plate, but is in the form of a conformal design, that is, the cross-sectional shape of the suspension mount 120 can locally protrude following the arrangement position of the avoiding notch 127, so that the wall thickness of the suspension mount 120 can be ensured to be basically the same, which meets the avoiding requirement while ensuring the overall strength of the suspension mount 120.

[0050] It is worth noting that in the present embodiment, the master cylinder 111 includes a crankcase 210 and an oil pan, the oil pan is detachably arranged at the bottom side of the crankcase 210 and surrounds to form a crank cavity, and the motor housing 112 includes an upper housing and a lower housing, the upper housing is integrally arranged at the rear end of the crankcase 210, the lower housing is integrally arranged at the rear end of the oil pan, and the suspension mount 120 is integrally arranged at the top end of the upper housing.
