Description

  The present invention relates to an electric vehicle such as an electric bicycle provided with a drive device and a battery that supplies electric power to the drive device.

  Conventionally, as this type of electric vehicle, for example, as shown in FIG. 19, there is an electric bicycle in which a switch device 102 is provided on a handlebar 101. The switch device 102 includes a power switch 103 and the like, and is electrically connected to a driving device 105 made of a motor or the like via a wiring 104.

  The vehicle body frame 106 is provided with a mounting portion 113 on which the battery 108 is detachably mounted. The standing pipe 107 of the vehicle body frame 106 is provided with a holding member 109 that holds the battery 108 mounted on the mounting portion 113. The holding member 109 has a holding cover 110 attached to the standing pipe 107, and a key lock device 111 for fixing the battery 108 to the holding member 109 is provided in the holding cover 110.

  According to this, assist travel is possible by pressing the power switch 103 of the switch device 102 to turn it on, and when the travel conditions such as travel speed and torque satisfy the predetermined travel conditions, the drive device 105 is driven to assist Driving force is applied to the rear wheels, and assist travel is started.

  In addition, the battery 108 is mounted on the mounting portion 113 and the key 108 is inserted into the key hole 112 of the key lock device 111 and rotated, whereby the battery 108 is fixed and held by the holding member 109.

Thereby, the mounting height of the key lock device 13 on the basis of the bracket 5 is accurately determined.

(D) Then, each latching claw 19 is engaged with each latching hole 20, the other cover body 11b is joined to one cover body 11a, and the holding cover 11 is assembled as shown in FIG.
(E) Thereafter, as shown in FIGS. 5 and 13, another screw 33 is inserted into the through hole 36 (see FIG. 4) of the other cover body 11 b and the lower screw hole 32 (see FIG. 7) of the sheet metal 24. The other cover body 11b is attached to the sheet metal 24 by being screwed onto the sheet metal 24.

  In the procedure (a), the switch device 12 and the wiring 40 are fixed to the one cover body 11a, and the one cover body 11a, the switch device 12 and the wiring 40 are integrated, thereby the procedure (d). In this case, when the other cover body 11b is coupled to the one cover body 11a, the switch device 12 is not dropped from the one cover body 11a and the wiring 40 is not obstructed. Processing and the like can be easily performed.
