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.

Description

[0001]This application claims the benefit of priority based on Taiwan Patent Application No 104201469, filed on Jan. 30, 2015, the contents of which are incorporated herein by reference in their entirety.CROSS-REFERENCES TO RELATED APPLICATIONS[0002]Not applicable.BACKGROUND OF THE INVENTION[0003]1. Field of the Invention[0004]This invention is regarding an electrical forward-moving assist apparatus. More precisely speaking, this invention is regarding an ultra-compact, low drag in water, hands-free and easy-to-install electrical forward-moving assist apparatus.[0005]2. Descriptions of the Related Art[0006]In prior art, diver propulsion vehicle requires user to hold the vehicle by hand to operate. This inconvenience greatly limited user's ability to perform other function. Also, during use underwater, a hand-held type vehicle could drift away unnoticed if left on the sea floor beside diver.[0007]For this reason, prior art as depicted in FIG. 1, the diver propulsion device 1 utilizes...

AI Technical Summary

Benefits of technology

The electrical forward moving assistant apparatus is a device that can be attached to a diver's equipment, like a scuba tank or BCD, and doesn't require them to hold it. It's designed to be compact and easily portable. The shape of the device is shaped to match the shape of the diver's equipment and the battery, so it's lightweight and can be easily carried. This allows the diver to have the assistance of the device while moving through water with less drag and effort.

Problems solved by technology

This inconvenience greatly limited user's ability to perform other function.

Even though diver propulsion device 1 in FIG. 1 can be operated hands-free, but its profile increased drag in water, and thus become user's burden when the vehicle lost its propulsion power due to low battery or malfunction.

Furthermore, the structure of diver propulsion device 1 is exposed and thus can be entangled by objects or cause damage to environment underwater.

Besides, the prior arts consider battery as an item which can only have basic geometry shape such as cylinder or box.

The exterior shape of the diver propulsion device is developed primarily based on the shape of the battery, causing the envelop dimension to become large or long.

Excessive size and weight subsequently become a burden too much for many divers to carry.

It simply cannot be light and compact enough for divers to carry easily.
