[detailed description]

In the following, the present invention is further described with reference to the embodiments and the accompanying drawings, which are intended to be illustrative only and not to limit the scope of the invention.

The frame combination structure of the electric vehicle in this embodiment is as follows:

As shown in FIG. 2, the frame assembly structure comprises: a frame including a rear fork riser, a riser pipe, a cross pipe, a front bottom pipe and a rear bottom pipe, wherein the pipe body is formed to form a frame, and the frame is enclosed The position of the accommodating cavity for fixing the battery case is formed, and the accommodating cavity has a frame fitting surface that is adhered to the battery case at least at the bottom, the rear portion and the front portion, and the battery case is fixed in the accommodating cavity The circumference of the battery box is closely fitted with the bonding surface in the accommodating cavity, and the position where the battery case and the frame are attached is also fixed by bolts, and the battery box is respectively disposed on the left side and the right side of the accommodating cavity. The left cover and the right cover are closed to form a closed cavity structure, and the rear part of the battery case is provided with an outlet hole communicating with the inside of the cavity, the upper part of the battery case has a light guiding hole, and the light guiding hole is provided with a light guiding column.

As shown in FIG. 1, a front side of the inner surface of the right cover is provided with a rechargeable battery and a charger, and the charger and the battery are connected by a charging circuit. The charging circuit may be that the output electrode of the charger is connected to the charging electrode of the battery through a wire, or a conventional circuit or a conventional circuit design is adopted according to the charging requirement of the electric vehicle. The charger generally has an indicator light indicating charging status, or some existing chargers use a display state such as a display panel to display the charging state of the charger, and the indicator light is in contact with one end of the light guiding rod to form a continuous optical path for guiding light. The light path can display the light of the indicator light. For example, the indicator light of many charging devices displays green when full, and red when not fully charged.
