Problems solved by technology
[0005] However, in the existing structure, since the battery case is made of resin, it may be difficult to effectively dissipate the heat emitted from the battery to the outside.
[0006] And because the battery box is fixed on the downpipe by connecting parts such as battery racks, a gap is likely to be generated between the downpipe and the connecting part or between the connecting part and the battery box, etc., thereby preventing the vehicle body from The front part of the problem of large-scale

Embodiment Construction
[0032] An embodiment of the present invention will be described below with reference to the drawings.
[0033] figure 1 It is a side view of the composite small motorcycle of this embodiment, and the small motorcycle is driven by the combined power of the internal combustion engine and the electric motor.
[0034] figure 1 Among them, 1 denotes a scooter, and this scooter 1 has a structure in which a steering shaft 2 a of a steering handlebar (hereinafter simply referred to as "handlebar") 2 is rotatably supported on a head pipe 3 . A down tube 4 extending rearward and downward in the front-rear direction of the vehicle body is connected to the head tube 3 , and a lower end of the down tube 4 is connected to an intermediate frame 5 branching toward the left and right of the vehicle body and extending substantially horizontally rearward. In the front portion of the middle frame 5, a battery 125 for supplying a control voltage of 12 volts to the engine 9 and lamps, etc. is arr...

Provided is a battery arrangement structure for an electric vehicle, which can efficiently dissipate the heat emitted by the battery to the outside, and can suppress the enlargement of the front portion of the vehicle body. The battery arrangement structure of the electric vehicle is provided with a down tube (4) extending rearward and downward from the head tube (3) in the front-rear direction of the vehicle body, and the battery (74) that supplies power to the power source motor is supported on the down tube ( 4) on the battery holder (90). The battery frame (90) is made of the same material as the downpipe (4), is integrally formed with the downpipe (4), and has an extension (91) extending in the vehicle width direction.
Description
technical field [0001] The present invention relates to a battery arrangement structure in an electric vehicle including a battery that supplies power to a power source motor. Background technique [0002] In general, there is a proposal for an electric motorcycle as follows: In the electric motorcycle, a downpipe extending from the headpipe in the front-rear direction of the vehicle body is provided, and a battery case made of resin is bolted to the downpipe. , The battery for power supply to the power source motor is accommodated in the battery box (for example, refer to Patent Document 1). [0003] This type of vehicle has the following advantages: since the battery is arranged along the down tube, even if a plurality of relatively heavy batteries are installed, the weight balance of the vehicle can be effectively maintained. [0004] Patent Document 1: Patent No. 3069808 [0005] However, in the conventional structure, since the battery case is made of resin, it may be...
