Electrical Forward-Moving Assistant Apparatus

Abstract

An electrical forward-moving assistant apparatus comprised of a housing, a motor, a battery unit, a propeller, a housing mounting fixture and a battery mounting fixture. The housing forms a watertight chamber. The housing mounting fixture is installed onto the housing to position the housing on one end of a cylinder body. The motor is installed inside the watertight chamber and connected to the propeller by a shaft which extends through the housing to provide thrust. The battery unit mounted on the cylinder body by the battery mounting fixture is connected to the motor via an electrical wire.

         6 . The electrical forward-moving assist apparatus as claimed in  claim 1 , further comprising an internal battery unit and a battery switch outside the housing, wherein the motor receives power from one of the at least one battery unit and the internal battery unit by the battery switch. 
     
     
         7 . The electrical forward-moving assist apparatus as claimed in  claim 1 , wherein the at least one battery unit comprises a plurality of battery modules electrically connecting to each other, and the at least one electrical wire electrically connects to one of the battery modules. 
     
     
         8 . The electrical forward-moving assist apparatus as claimed in  claim 1 , wherein the at least one battery unit comprises a battery management device and a plurality of battery modules electrically connecting to each other, and the battery modules and the at least one electrical wire electrically connect to the battery management device. 
     
     
         9 . The electrical forward-moving assist apparatus as claimed in  claim 1 , wherein the at least one battery unit comprises a power supply terminal, and an appliance draws power via the power supply terminal from the at least one battery unit. 
     
     
         10 . The electrical forward-moving assist apparatus as claimed in  claim 1 , further comprising a controller and a control wire, wherein the controller electrically connects to the motor to control the motor. 
     
     
         11 . The electrical forward-moving assist apparatus as claimed in  claim 10 , further comprising a controller pocket mounted on the housing, wherein the motor electrically connects to the controller via the controller pocket and the control wire. 
     
     
         12 . The electrical forward-moving assist apparatus as claimed in  claim 11 , wherein the controller pocket contains the controller and retrieves the control wire. 
     
     
         13 . The electrical forward-moving assist apparatus as claimed in  claim 1 , further comprising a wireless controller for controlling the motor.
