Description

Artificial Intelligence Type Electric Carrier Bag and Moving Control Method Thereof}

The present invention relates to an intelligent electric carrier bag, and more particularly, by mounting an inclination sensor on one side of a carrier bag on which a wheel is driven by an electric device to determine the operation of the electric device according to the degree of inclination. The present invention relates to an AI-type electric carrier bag that improves the usability of a bag such that the electric device is driven or stopped only by tilting or sizing the bag without operating the on / off switch, and a driving method thereof.

Representative bags used for overseas business trips or travel abroad are mainly used a large-capacity carrier bag equipped with wheels at the bottom to accommodate a large amount of goods and to move easily.

The carrier bag has a structure in which a pair of wheels is rotatably coupled to one side edge portion of the lower portion of the bag body, and a handle portion is releasably coupled to an upper portion of the upper portion of the bag body in which the wheel is mounted. The carrier bag of the structure is to be in contact with the wheel only when the user tilts the handle during the movement in this state to minimize the friction with the ground to make the movement.

The basic carrier bag has been proposed to connect the wheels to the shaft for the convenience of the user, and to rotate the shaft by the drive of the motor so that the user can automatically move without having to pull the bag.

For example, Utility Model Registration No. 20-0429351 (registered October 16, 2006), the electric carrier bag 110 shown in Figs. 1 and 2 is a bag 111 that can accommodate the article is coupled to the frame portion 112 The battery 113 and the drive motor 114 is mounted to the frame portion to suggest a configuration to move to electricity. The gun has a structure in which the frame part is exposed to the outside of the bag, the battery and the driving motor are also installed in the outer frame part, and the operation means 115 of the driving motor is also installed in the handle 116 connected to the frame part. That is, the gun may be referred to as a structure to move the bag to the carrier device rather than the carrier bag is mounted directly on the wheel. In addition, the operation means is also composed of basic operation buttons, such as power on and off and start or stop button, the user must press the button during start and stop. If the button is not pressed quickly, there is a problem that the device may proceed excessively and cause contact accidents.

In addition, Patent Publication No. 10-2005-0014405 (published on Feb. 07, 2005), as shown in FIG. 3, is provided with a driving motor 122 and a rechargeable battery 123 inside the main body 121 of the carrier bag 120. Only the vertical frame 125 and the wheel 126 and the wheel shaft 124 is formed to have a form that is expressed to the outside. The gun further installs an auxiliary shaft 127 further formed with wheels for the user to easily move. However, there is an inherent problem of causing contact accidents due to the excessive progression described above by determining whether or not to proceed by adjusting the driving motor only by the on-off switch 128 of the gun handle.

Therefore, there is a need for a new device structure that can control the driving of the drive device in a manner other than the control of the drive motor by the on / off switch.

Hereinafter, the present invention will be described in detail with the accompanying drawings.

Figure 4 is a perspective view of the electric carrier bag according to an embodiment of the present invention, Figure 5 is a block diagram of the electric carrier bag according to an embodiment of the present invention, Figure 6 shows a takeout handle according to an embodiment of the present invention. Partial perspective view.

As shown, the artificial intelligence-type electric carrier bag 10 according to the present invention includes an upper accommodation chamber 30 containing an object therein, and a lower transmission chamber 40 in which a battery 41 and an electric motor 42 are placed. It is provided with a main body 20 in the form of a bag divided into. In addition, the partition plate 21 for partitioning the upper compartment and the lower electric compartment is formed of a material of high strength to completely separate the space, not a simple partition, and the object stored in the upper compartment is moved to the lower compartment, or the upper compartment It is desirable to prevent the shock applied from the seal from being transferred to the lower transmission chamber.

In addition, the main body 20 may have a handle 22 formed on one side to directly lift the main body, and an opening and closing means including a jacquard and a button may be formed on the side or the front to open and close the main body. Here, since the main body is partitioned into an upper compartment and a lower electric compartment, it is preferable to open and close each compartment separately.

An electric motor 42 and a battery 41 are provided in the lower electric chamber 40 of the main body. The electric motor 42 has the output gear 43 is integrally coupled to the end of the motor shaft to be rotated by receiving power from the battery, and to have a capacity capable of providing a speed of at least 1 ~ 6km / h. . In addition, a reduction gear is further installed between the electric motor 42 and the output gear 43 to decelerate the motor and increase torque, or install a motor driver on one side of the electric motor to precisely control the driving of the electric motor. have.

In addition, the drive shaft 60 is inserted into the lower transmission chamber 40 of the main body, and the lower transmission chamber is rotatably fixed by the bearing 44. In this way, the drive shaft 60 is integrally coupled to a portion located inside the lower transmission chamber to the drive shaft 60 is installed so that the power of the electric motor is transmitted by engagement with the output gear 43.

In addition, the torque can be further increased by adjusting the gear numbers of the output gear 43 and the drive shaft gear 61. For example, the number of gears of the drive shaft gear may be greater than the number of gears of the output gear to reduce the speed and increase the torque in the power transmission process from the output gear to the drive shaft gear.

Wheels 70 are coupled to both ends of the drive shaft 60 that is exposed to the outside of the main body. The wheel is installed to protrude outward from the side of the main body, or as shown in the groove portion is formed inward in the main body portion in which the drive shaft end is located, and the wheel is inserted in the groove to install the wheel from the main body side The protruding length can be minimized.

Next, one side surface of the main body (preferably the main body rear surface close to the installed wheels) is drawn out to the upper portion is formed with a pull-out handle 50 to facilitate the bag dragging when moving. The withdrawal handle has a structure with a withdrawal bar in the same manner as that formed in a normal carrier bag. However, the withdrawal knob 50 of the present invention is provided with an operation panel 51 to control the drive by the electric motor to be described later.

The operation panel 51 includes a power button 52, a speed up button 53, a speed down button 54, and a display unit 55. The power button is a button for supplying the power of the battery to the electric motor, the speed up button and the speed down button is a button to increase or decrease the movement speed of the wheel by adjusting the number of revolutions of the electric motor. At this time, in order to precisely adjust the rotational speed of the electric motor may be a motor driver is further installed in the electric motor. In addition, the controlled speed may be divided into a plurality of steps, and the level of each step may be displayed on the display unit 55 by displaying the level of each step by numbers or letters.

The operation panel 51 having such a configuration may be formed on all of the upper surfaces of the pullout handle 50, or some configuration may be installed on the side of easy button operation. For example, as shown in FIG. 6, the power button 52 and the display unit 55 are positioned on the upper surface, and the speed up button 53 is located on the side where the thumb is located when the user grips the draw handle by hand. The speed down button 54 can be positioned so that the button can be easily operated during the movement.

The electric carrier bag of the present invention is further provided with a tilt sensor 80 for measuring the tilt, and a controller 90 for driving the electric motor by controlling the signal or various signals of the tilt sensor. The inclination sensor 80 may be used in a variety of known structures, it may be installed on any one side of the main body or withdrawal handle fixed to the main body, preferably the inclination sensor 80 can be protected from external impact It is to be installed in the lower electric chamber 40 of the main body. In addition, the control unit may be installed in the lower electric compartment to prevent external shock transmission and contamination by foreign matters.

The control unit 90 controls the electrical signal of the electric carrier bag 10 according to the present invention. For example, the control unit determines the output supply of the electric motor 42 by the signal of the inclination sensor 80 for measuring the inclination of the main body, so that the driving is made by the inclination of the bag without the operation operation separately It is possible to provide a bag.

In addition, the electric carrier bag of the present invention may be coupled to the bearing between the drive shaft 60 and the drive shaft gear 61 in order to minimize the resistance in the driving direction during the manual drive in addition to the drive by the electric drive. That is, in the manual operation, the installed electric motor, the output gear and the drive shaft gear or the reducer act as a resistance to the driving, so that power is transmitted only in one direction between the drive shaft and the drive shaft gear in order to minimize the transfer of the resistance, and the other side is wasteful. It is to insert the one-way bearing 62 to turn.

As shown in FIG. 7, when the one-way bearing 62 is inserted, the drive shaft gear 61 rotates counterclockwise by the engagement from the output gear 43, and the one-way bearing 62 rotates the drive shaft gear. Electric force acts on the drive shaft, and power transmission is achieved by toothing.

On the contrary, when the bag is manually dragged, the driving shaft 60 rotates clockwise first, and the rotational force acts in the driving shaft bearing direction at the driving shaft. In this one-way bearing 62, the output gear and other electric motors can be prevented from acting as a resistance by turning away without transmitting power according to a conventional ratchet principle. For example, the ratchet is rotated by the hinge pin so that the latch is not locked by the rotation in the other direction even when the latch is caught only in one direction.

Of course, in addition to the one-way bearing installed between the drive shaft and the drive shaft gear, the one-way bearing is inserted between the output gear and the output shaft of the electric motor to prevent the electric motor shaft from rotating according to the rotation of the drive shaft gear during manual operation. The occurrence of reverse electric current in the electric motor can be prevented.

Looking at the operation state briefly, if the inclination of the bag while the power button 52 on the drawer handle 50 is turned on, the tilt sensor 80 detects this, so that the electric power is output from the electric motor 42, The output electric force rotates the output gear 43 integrally installed at the end of the electric motor shaft, and is transmitted to the drive shaft 60 through the drive shaft gear 61 engaged with the output gear, and integrally coupled to both ends of the drive shaft. The final transfer to the wheel 70 is made of the driving of the electric motor electric power. In addition, when the bag is standing while driving, the inclination sensor 80 detects this to cut off the output of the electric motor 42 to stop the driving by electric.

A driving method of the electric carrier bag having the above configuration will be described with reference to FIGS. 8 and 9.

First, when the power button is turned on (on), the step of preparing to supply the power of the battery power supply unit to the electric motor is performed. For example, when a motor driver is installed, the power is supplied to the electric motor when the power button is operated, but the operation is stopped by the motor driver. When the motor driver is not installed, the control unit prepares to supply power to the electric motor. It becomes a state.

Next, the controller detects the inclination of the bag. That is, when the bag is inclined while the power button is turned on, the inclination sensor installed on one side of the bag detects the inclination and transmits the detected signal to the controller so that the controller determines whether the bag is inclined. In this case, the inclination sensor preferably transmits the inclination detection signal to the controller when the bag is inclined at a predetermined angle or more. For example, when the bag is tilted more than 10 °, the tilt sensor transmits the tilt detection signal to the control unit so that the detection is performed.

The control unit receiving the inclination detection signal is performed to supply the power of the power supply unit to the electric motor to output the electric force from the electric motor. Of course, when the motor driver is installed, the electric motor is driven by releasing the lock of the motor driver.

In addition, the step of performing the driving by transmitting the electric power output from the electric motor to the wheel is performed to move the bag to the electric power.

In this case, the driving step may further include increasing or decreasing the driving speed by operating the speed up button and the speed down button of the operation panel.

When the speed up or down button is operated in the driving process, each button transmits a speed control signal that is a speed up or speed down signal to the controller. When the speed control signal is received, the control unit directly intervenes the electric motor or intervenes with the motor driver to increase or decrease the rotation of the electric motor to increase or decrease the running speed.

In addition, the running speed may be divided into a plurality of classes so that each speed class may be selectively made. For example, between the stationary state and the maximum speed that can be driven by the electric motor is divided into equal intervals by the desired number, and the speed in each of the above classes is set in advance and stored. When the speed up button or the speed down button is operated while driving, the speed control signal is transmitted to the control unit, and the control unit controls the electric motor or the electric driver to change the set speed of the upper or lower grade based on the current speed. .

In addition, each of the speed grades may be displayed in letters or numbers so that the letters or numbers corresponding to the speed grades may be displayed on the display only when the speed up button or the speed down button is operated. That is, the letters and numbers corresponding to the speed grade and the speed grade are set in advance so as to adjust the number of rotations of the electric motor at the time of speed adjustment and to transmit and display the letters or numbers of the corresponding speed grade to the display. It can provide the user with the current speed class information.

Meanwhile, when the bag is standing upright while driving, the tilt sensor transmits an output cutoff signal to the controller.

When the output cutoff signal is input to the controller, the controller is configured to stop the driving of the wheel by cutting off the electric force output from the electric motor.

Here, the output cutoff signal may be a separate signal, and may block the tilt detection signal continuously supplied to the controller during tilting. In addition, when the output cutoff signal is input, the control unit cuts off the output by cutting off the power of the electric motor or blocking the transmission of the output by the motor driver.

When the bag is inclined again in the stopped state when the output is cut off, driving is resumed through the process as described above, and when the power button is turned off, the control unit cuts off all the power supplied from the power supply to drive the electric motor. It stops and enables the movement of the bag only in manual mode.
