Problems solved by technology

Since the motor is provided on a swing arm that pivots vertically according to the state of the road surface, the distance between the battery and the motor changes as the swing arm pivots, and there may be a situation where a tensile load is generated in the power supply cable

Embodiment Construction

[0029] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. In each drawing used in the following description, the drawing scale is changed as necessary so that each constituent member is illustrated in a good size for easy identification.

[0030] figure 1 is a left side view showing a two-wheeled electric vehicle according to an embodiment of the present invention. In this embodiment, the two-wheeled electric vehicle 1 in the form of a scooter will be described as a straddle electric vehicle. The two-wheeled electric vehicle 1 can run with luggage placed on its front and rear and is suitable for a luggage handling vehicle.

[0031] The directions expressed as front and rear, up and down, and left and right are based on the standard posture of the two-wheeled electric vehicle 1 and the driver's perspective when the driver faces the front of the vehicle, which corresponds to the straight forward movement of the two-wheel...

Abstract

A swing arm (47) is supported on a vehicle body frame (2) in such a way as to be able to swing, while also supporting a wheel (4). A motor (5) is supported on the swing arm (47) and drives the wheel (4). A battery (6) is supported on the vehicle body frame (2). A cable (81) supplies power from the battery (6) to the motor (5). Part of the cable (81) is routed in such a way as to form a curved portion along a side surface (6b) of the battery (6).

Description

technical field [0001] The invention relates to a straddle type electric vehicle. Background technique [0002] An electric motor that drives wheels of the straddle-type electric vehicle and a battery that supplies electric power to the electric motor are connected by a power supply cable. Since the electric motor is provided on the swing arm that pivots vertically according to the state of the road surface, the distance between the battery and the motor changes as the swing arm pivots, and there may be a situation where a tensile load is generated in the power feeding cable. [0003] In order to alleviate this load, there is known a technique in which a portion where the power feeding cable is bendable is provided at a halfway position along the length of the routing path of the power feeding cable so that the power feeding cable can be deformed to follow the displacement of the swing arm (e.g. , refer to Patent Document 1). [0004] prior art literature [0005] [Patent...
