Problems solved by technology

If the width of the battery box becomes larger, the crank that connects the pedals and the battery box will become narrower, and there will be a danger of fingers being caught between the crank and the battery box. Therefore, it is necessary to make it impossible to install a large-capacity battery box until it is used. On the body of the conventional battery box

Embodiment Construction

[0037] Embodiments of the present invention will be described in detail below based on a power-assisted bicycle shown in the drawings.

[0038] exist figure 1 Among them, the body of the power-assisted bicycle 1 includes: a front fork 3 supporting a front wheel 2, a down tube 4, a seat post 6 supporting a seat 5, a chain bracket 8 supporting a rear wheel 7, a seat bracket 9, and connecting pedals. 10 cranks 11 etc. A hub unit 13 with a built-in electric motor is arranged on the front wheel 2 , and a battery box 14 is mounted between the seat post 6 and the rear wheel 7 . A sensor (not shown) is equipped on the position where the pedaling force applied to the pedal 10 acts. ) to apply electric drive force.

[0039] based on Figure 1 to Figure 8 , the battery box 14 is described in detail. A plurality of battery cells (not shown) are accommodated inside the battery box 14. The shaft portion 15 on the side surface is engaged with a not-illustrated groove portion formed in t...

Abstract

The invention discloses an electric assisted bicycle, in which the original battery box can be installed on a body loading a high-capacity battery box and the high-capacity battery box cannot be installed on a body having the original battery box. The body is provided with a terminal plate (21) having a connection terminal connected with an electric unit. The battery box (14) having a connection terminal connected with the connection terminal is installed so as to swing when being supported on the terminal plate (21). A locking mechanism (23) is arranged on the body. The locking mechanism (23) and the battery box (14) are clamped so as to fix the battery box (14) in a free clamping separation way. A bump (17) is formed on the battery box towards the locking mechanism (23). A notch part (25) preventing the bump (17) from being in butting joint is formed on the locking mechanism (23).

Description

technical field [0001] The present invention relates to an improvement of a power-assisted bicycle having a human-powered drive system that transmits pedaling force based on pedals and a motor drive system that transmits power from an electric unit. Background technique [0002] Conventionally, electric-assisted bicycles are configured to detect pedaling force by pedals, and transmit electric driving force corresponding to the pedaling force to assist human power. A battery box for supplying electric power to a power unit that outputs electric driving force is detachably mounted between a seat post and a rear wheel of a vehicle body as disclosed in Patent Document 1, for example. [0003] The battery box is configured to swing around the hooked portion as a fulcrum while the lower end is hooked to the battery bracket arranged on the vehicle body, and the upper end side of the battery box is engaged with a locking mechanism arranged on the vehicle body. [0004] In recent ye...
