[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] A highly safe two-wheeled electric bicycle powered by sodium batteries comprises a sodium-ion battery pack and an electric bicycle body. The electric bicycle body includes a cavity containing a battery compartment. The battery compartment comprises a relatively fixed bottom plate and front baffle, and relatively movable side and rear baffles. The upper end of the battery compartment is an opening for accommodating the sodium-ion battery pack. The upper edges of the front, side, and rear baffles are each provided with an arcuate guide surface. Return springs are located on the outer surfaces of the side and rear baffles, with one end resting on the surface of the battery compartment and the other end resting on the cavity wall. The side and rear baffles also feature several spring retaining seats for positioning one end of the return spring. A telescopic sleeve is sheathed around the return spring, with one end fixed to the surface of the battery compartment and the other end fixed to the cavity wall. A cushioning rubber pad is provided on the inner wall of the battery compartment. The bottom surface of the bottom plate also features a cushioning layer. A cable port is provided on the front baffle, through which the cable plug for the electric bicycle body is routed. A reel device is also provided in the electric bicycle body, and the reel device winds up the cable plug of the electric bicycle body.

[0025] The actual usage is as follows:

[0026] There is a cavity in the body of the electric bicycle, which can usually be set under the seat or in other larger spaces. The battery compartment is set in the cavity. When the battery pack is not placed in the battery compartment, the side baffles and rear baffles of the battery compartment are pressed by the return spring (at this time the overall space of the battery compartment is small), and the sodium ion battery pack is placed in the battery compartment from the upper opening. Since the upper edges of each baffle of the battery compartment are provided with arc-shaped guide surfaces, the battery pack can be quickly aligned and placed in the battery compartment. When the battery pack is placed in the battery compartment, the side baffles and rear baffle can adapt to the size of the battery pack through the return spring.

[0027] A reel device is provided inside the electric bicycle body, which can wind up the cable plug wire. The reel device also has a reset torsion spring. When not in use, the cable plug can be automatically retracted to the cable port, and the sodium-ion battery pack can be pulled out through the pull ring.

[0028] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present invention is limited by the appended claims rather than the above description. Therefore, it is intended that all changes that fall within the meaning and scope of the equivalent elements of the claims are included in the present invention.
