In one embodiment, as shown in fig. 3 and 4, the crank flywheel assembly includes a middle shaft 31, a chain wheel 32, a first crank 33 and a second crank 34, the middle shaft 31 is disposed on the first body portion 11, the chain wheel 32 is sleeved on the middle shaft 31, the first crank 33 is connected to a first end of the middle shaft 31, the second crank 34 is connected to a second end of the middle shaft 31, and the chain wheel 32 is used for driving a chain.

In this embodiment, the sprocket 32 and chain drive are capable of driving an electric vehicle. The rotation of the first crank 33 and the second crank 34 drives the middle shaft 31 to rotate, and the rotation of the middle shaft 31 drives the chain wheel 32 to rotate. As will be understood by those skilled in the art, the middle shaft 31 is disposed on the first body portion 11 in a manner that the middle shaft 31 can rotate around its axis as a center line, thereby performing a transmission function.

And, the ends of the first and

second cranks

33, 34 remote from the central axis would be provided with pedals for manual actuation to facilitate the actuation of the crank flywheel assembly by the user while riding.

For example, the first body portion 11 is provided with a structure for supporting the middle shaft 31, so that the middle shaft 31 is mounted on the first body portion 11.

In one embodiment, as shown in fig. 2, a housing 4 is disposed between the battery compartment 2 and the first main body 11, the housing 4 forms a receiving cavity, the sprocket 32 is located in the receiving cavity, and two ends of the middle shaft 31 extend out of the receiving cavity.

In one embodiment, the sidewall is provided with two opposite through holes 41, a first end of the central shaft 31 extends from one of the through holes 41, and a second end of the central shaft 31 extends from the other through hole 41.

The first end and the second end of the bottom bracket 31 need to be connected with the first crank 33 and the second crank 34, respectively. Through holes 41 are provided in the side walls to allow the first and second ends of the central shaft 31 to extend to form a connection. The through holes 41 do not affect the protection of the accommodating cavity formed by the side walls to the crank flywheel assembly, and the first crank 33 and the second crank 34 can be located outside the accommodating cavity, so that the user can ride conveniently. It is easier to interact with the pedals on the first and

second cranks

33, 34 during riding, without interacting with the components inside the housing chamber.

In one embodiment, the housing 4 is integrally formed with the battery compartment 2.

In the process of forming parts of the electric vehicle, the battery compartment 2 and the shell 4 are integrally formed, and the integrally formed battery compartment 2 and the shell 4 are installed at one time during assembly.
