Self-balancing electric motorized luggage

Abstract

The present invention produces a self-balancing electric motorized luggage capable of relieving the user from the burden of luggage weight handling, in particular, continue usability on inclines, uneven surfaces and crowded spaces.

With utilizing of the gyroscope self-balancing system and two motorized wheels, the self-balancing electric motorized luggage is capable of auto-adjusting its centre of gravity point to remain self-balanced in an upright position during operation. When in motion, the luggage will synchronize with the user's speed and running surface by automatically reducing its speed down a decline or increasing power when up an incline. In addition, this luggage is designed with a U-shaped width bottom, and uses narrow depth of the main container as lead to a direction. This configuration allows the user to have close control of the luggage operating beside them. With motor/user synchronisation, nearly all physical stresses on the arm, shoulders and back are removed.

DETAILED DESCRIPTION OF THE INVENTION

[0038] The self-balancing electric motorized luggage pertains to a portable Self-balancing motorized travel luggage which can operate in either the Self-balancing motorized mode or Manual rolling mode.

[0039] The self-balancing electric motorized luggage means maintaining an upright position by its centre of gravity, fully capable of managing its net weight and in real time maintains the balancing between its motor wheels during operation. It uses a variety of electrical processors comprising of FIG. 1 reference line 3 a Gyro sensor mounted thereon to maintain the balancing between FIG. 1 reference line 6 the two motor wheels of 200 m motorized wheels with inflatable pneumatic tires, the variety of electrical processors are operated by FIG. 1 reference line 7, 8 a main controller board housing the Micro and Motor controller, powered by the FIG. 1 reference line 4 the Rechargeable battery pack and controlled by four switch buttons to form a Gyroscope self-balancing system and thereby maintaining the balancing.

[0040] FIG. 1 reference line 4 the Rechargeable pack comprises of a pack of 24 Volt rechargeable batteries with a step-down generator is electronically connected to FIG. 1 reference line 7, 8 the main controller board, and supply a predetermined level of energy to the Set of motor wheels corresponding to selection of the operator. The Rechargeable battery pack is snap-fit into the inner shell of the main container to allow for easy installation and removal in accordance to airport security. Note: The snap-fit housing is not illustrated in the drawings provided.

[0041] The self-balancing electric motorized luggage moves in accordance with the inclinations of a gentle push or pull of the user. The inclinations of the user are sensed in real time through the Gyro sensor, and based upon the sensed results are calculated through the main controller board to activate the Set of motor wheels, while preventing the self-balancing electric motorized luggage from over turning. That is, the motor wheels are activated in real time in accordance with the values of the inclinations of the user movements, so the luggage can be performed in the state where the self-balancing motorized luggage is always upright. With this technique the luggage can always be synchronized with the user's walking speed, while carrying the weight up or down an incline without losing balance. FIG. 3 the U shaped design makes it possible for the luggage to go up or down an incline in an upright position.

[0042] The self-balancing motorized travel luggage can operate in two operation modes, a Self-balancing mode and a Manual mode. In FIG. 2 the Self-balancing mode, FIG. 1 reference line 2 the first extendable handle is used to transfer the inclinations between the user and the Set of two motor wheels. A Set of four buttons, an On/Off switch button, a Pause/Resume function switch button and two Arrowed switch buttons are used as control during the Self-balancing mode. All buttons are used to execute a respective command and connected electronically to the gyroscope self-balancing system. Note: All switch button embodiments are not illustrated in the drawings provided, may change in number, or located separately on different parts of the luggage. The On/Off switch button is electronically connected to the Rechargeable battery pack for supplying or cutting off electrical power when toggled. The Pause/Resume button is connected to FIG. 1 reference line 7, 8 the main controller board to stop or resume all motor functions, with the gyroscope self-balancing system still receiving power and on standby. When Pause is activated, the current centre of gravity point value will be recorded in memory, and then the motor wheels become free moving. When Resume is activated, the motor function will resume when the previous centre of gravity point value is found by the gyroscope sensor. The Two arrowed switch buttons are for manually adjusting the luggage's centre gravity to forward or backwards to an appropriate upright position.

[0043] That is, FIG. 1 reference line 5 the metal housing along with the main container will adjust its axis forward or backwards irrespective of the motor wheels movement and, in accordance to the user control. This is for scenarios such as shifting contents inside the luggage or to exert more control over the luggage on an incline.

[0044] During operation in the Self-balancing mode, a method of using FIG. 2, FIG. 5, FIG. 6 the depth of the main container of A Side or B Side to lead the direction forward or backwards, this means using the narrowest or smallest front or back facing surface area as lead. This is an ergonomic and space saving design aimed for the luggage to operate on either the left or right hand side of the user. This allows the user full control over luggage manipulation beside of them, enhancing safety to oneself and the public. Nearly all physical stresses on the arm, shoulders and back are removed due to the elimination of dragging or pushing the luggage. Note: User should only operate the luggage on either side and not in front of or behind them.

[0045] In FIG. 2 the Manual mode, the present invention can be re-position to operate on FIG. 1 reference line 9 & FIG. 4 reference line 3 a Set of manual wheels comprising of two roller ball bearing wheels and, two Omni-direction wheels that are attached on either FIG. 5 A Side or B Side of the main container, for moving along the ground as illustrated in FIG. 4. FIG. 4 reference line 1 the second extendable handle is used to guide the luggage to any direction on four wheels or can be dragged behind the user when inclined on two wheels. This manual mode allows the user to operate the luggage during power-out situation or the Rechargeable battery pack removal for checking-in luggage.
