Electric outboard motor

Abstract

An electric outboard motor for propelling a boat, includes: a propeller unit; a motor; a first battery and a second battery; an accommodation portion; and a support portion. The first battery is disposed in the accommodation portion such that a thickness direction thereof is an upper-lower direction of the electric outboard motor, and is located above the support portion. The second battery is disposed in the accommodation portion such that a thickness direction thereof is a front-rear direction of the electric outboard motor, and is located rearward of an upper portion of the support portion.

1 . An electric outboard motor for propelling a boat, the electric outboard motor comprising:
 a propeller unit including a propeller shaft, a propeller fixed to the propeller shaft, and a case rotatably supporting the propeller shaft, the propeller unit being disposed at a lower portion of the electric outboard motor;   a motor configured to rotate the propeller shaft;   a first battery and a second battery configured to supply electric power for driving the motor to the motor;   an accommodation portion accommodating the first battery and the second battery, the accommodation portion being disposed at an upper portion of the electric outboard motor; and   a support portion formed in a columnar shape extending in an upper-lower direction, the propeller unit being supported at a lower portion and the accommodation portion being supported at an upper portion, wherein   each of the first battery and the second battery is formed in a rectangular parallelepiped shape having a thickness dimension smallest among a length dimension, a width dimension, and the thickness dimension,   the first battery is disposed in the accommodation portion such that a thickness direction thereof is the upper-lower direction of the electric outboard motor, and is located above the support portion, and   the second battery is disposed in the accommodation portion such that a thickness direction thereof is a front-rear direction of the electric outboard motor, and is located rearward of the upper portion of the support portion.   
     
     
         2 . The electric outboard motor according to  claim 1 , wherein the first battery is disposed in a position intersecting a first straight line that passes a center of the support portion in the upper-lower direction, and the second battery is disposed in a position intersecting a second straight line that passes an intersection of an upper end surface of the support portion and the first straight line and extends in the front-rear direction. 
     
     
         3 . The electric outboard motor according to  claim 1 , wherein an upper end of the second battery aligns with an upper surface of the first battery in the upper-lower direction, or is located below the upper surface of the first battery. 
     
     
         4 . The electric outboard motor according to  claim 1 , wherein a rear end of the first battery aligns with a rear surface of the second battery in the front-rear direction, or is located forward of the rear surface of the second battery. 
     
     
         5 . The electric outboard motor according to  claim 1 , wherein the support portion is provided with a transom bracket configured to attach the electric outboard motor to a transom of the boat, and a lower end of the second battery is located below an upper end of the transom bracket. 
     
     
         6 . The electric outboard motor according to  claim 1 , wherein the support portion is provided with a transom bracket configured to attach the electric outboard motor to a transom of the boat, and a front end of the first battery is located forward of a rear end of the transom bracket. 
     
     
         7 . The electric outboard motor according to  claim 1 , wherein a steering bar handle is disposed above and forward of the support portion, and an upper end of the second battery is located below a position of a base end portion of the bar handle. 
     
     
         8 . The electric outboard motor according to  claim 1 , wherein a steering bar handle is disposed above and forward of the support portion, and a position of the first battery substantially aligns with a position of a base end portion of the bar handle in the upper-lower direction. 
     
     
         9 . The electric outboard motor according to  claim 1 , wherein the support portion is provided with, at an upper end portion, an attachment plate portion configured to attach the accommodation portion, and the attachment plate portion is formed in a plate shape inclined such that a rear end is located below a front end. 
     
     
         10 . The electric outboard motor according to  claim 9 , wherein the accommodation portion includes a wall portion surrounding the first battery and the second battery, the wall portion includes an attachment wall portion configured to attach the accommodation portion to the attachment plate portion, and the attachment wall portion is inclined such that a rear end is located below a front end.
