"A BATTERY MOUNTING STRUCTURE FOR AN ELECTRIC VEHICLE"

Abstract

A battery mounting structure for an electric vehicle (1; 100), wherein said electric vehicle is provided with a body frame (2) where a front frame (4; 102) is extended from a head pipe (3; 101) toward the rear of the body diagonally downward and which is run using a motor as a driving source, wherein: a battery (70; 120) for supplying power to the motor is attached to the front frame (4; 102) of the body frame (2) such that plural batteries (73M, 73L, 73R; 123L, 123R) attached to the front frame (4; 102) of the body frame are arranged in a circumferential direction, characterized in that the radiating face of the battery (70; 120) is directly exposed to running wind, wherein an interval between each battery is wider in each lower part than an interval in each upper part.

[Technical Field] [0001] The present invention relates to battery mounting structure in an electric vehicle which can be run using a motor as a driving source. [Background Art] [0002] This type of electric vehicle has a large battery for driving a motor and has a problem of a location for arranging it, however, as to a vehicle in which a front frame is extended from a head pipe toward the rear of the body diagonally downward, there is an example (for example, refer to a patent document 1) in which a battery is provided along the front frame. [Patent Document 1] JP-A No. 105142/1993 [0003] In the patent document 1, in a motorcycle in which a front pipe is extended diagonally downward from a head pipe toward the rear of the body, structure where the bottom of a battery box is fastened to a bracket welded to the front pipe by a bolt, the front of a battery housed in the battery box is covered with an inner fender, the rear is covered with a cover for closing an opening of a leg shield and the battery is arranged in closed space is disclosed. [Disclosure of the Invention] [Problem to be Solved by the Invention] WE CLAIM: 1. A battery mounting structure for an electric vehicle (1; 100), wherein said electric vehicle is provided with a body frame (2) where a front frame (4; 102) is extended from a head pipe (3; 101) toward the rear of the body diagonally downward and which is run using a motor as a driving source, wherein: a battery (70; 120) for supplying power to the motor is attached to the front frame (4; 102) of the body frame (2) such that plural batteries (73M, 73L, 73R; 123L, 123R) attached to the front frame (4; 102) of the body frame are arranged in a circumferential direction, characterized in that the radiating face of the battery (70; 120) is directly exposed to running wind, wherein an interval between each battery is wider in each lower part than an interval in each upper part. 2. A battery mounting structure as claimed in claim 1, wherein radiating fins (71Lc, 71 Rc; 121Lc, 121Rc) are provided to the radiating face of the battery. 3. A battery mounting structure as claimed in any of claims 1 or 2, wherein the battery (73L, 73R) is arranged on the left and on the right with the front frame (4) of the body frame therebetween; and another battery (73M) is arranged along the front frame. 4. A battery mounting structure as claimed in any of claims 1 to 3, wherein the battery is covered with a front cover (112) and a rear cover (113) from the front and the rear of the body; and a cooling wind intake (121 h) is formed on a front wall that faces the front of the body of the front cover. 5. A battery mounting structure as claimed in claim 4, wherein a louver (131) is provided to the cooling wind intake (12 lh). 6. A battery mounting structure as claimed in claims 4 or 5, wherein a cooling wind exhaust port (113h) is formed on the rear cover. 7. A battery mounting structure as claimed in claim 6, wherein the cooling wind exhaust port (113h) is formed on the side wall (113Ls, 113Rs) of the rear cover (113) overlapped with the side wall (112Ls, 112Rs) of the front cover (112) inside when they are viewed from the side of the vehicle. 8. A battery mounting structure as claimed in claim 6 or 7, wherein a louver (132) is provided to the cooling wind exhaust port (113h).
