     DETAILED DESCRIPTION 
     Hereinafter, an explanation on a backpack type bag with a self-balancing electric vehicle mounted thereon according to the present invention will be in detail given with reference to the attached drawings. 
     According to the features of the present invention, first, a user can ride a self-balancing electric vehicle on which a backpack type bag is mounted, and if riding is not needed, the user can carry the backpack type bag on his shoulders, thereby optimizing the conveniences in the carrying and moving works. 
     The self-balancing electric vehicle means a general upright riding electric vehicle, that is, a self-balancing electric vehicle that in real time maintains the balancing between two wheels during riding. The self-balancing electric vehicle has a variety of electrical processors inclusive of a Gyro sensor mounted thereon to maintain the balancing between the two wheels, and the variety of electrical processors are operated by the control of a controller, thereby maintaining the balancing. 
     The self-balancing electric vehicle is moved in accordance with the inclinations of a rider&#39;s body. In more detail, the inclinations of the rider&#39;s body are sensed in real time through the operation of the controller inclusive of the Gyro sensor, and based upon the sensed results, the wheels are activated, while the overturning of the self-balancing electric vehicle is being prevented. That is, the wheels are activated in real time in accordance with the values of the inclinations of the rider&#39;s body, so that the riding can be performed in the state where the self-balancing electric vehicle is upright. 
       FIG. 6  is a perspective view showing the assembled state of the backpack type bag with a self-balancing electric vehicle mounted thereon according to the present invention, and as shown in  FIG. 6 , a user can walk in a state of carrying a backpack type bag  10  on his back, and if riding is needed, the backpack type bag  10  is placed on the ground to lift a handle  21  therefrom, so that he can ride with the inclinations of his body by using the above-mentioned self-balancing principle. 
       FIG. 1  is a separate perspective view showing a frame of a backpack type bag with a self-balancing electric vehicle mounted thereon according to the present invention, and  FIG. 2  is a perspective view showing a support rod of the backpack type bag according to the present invention. As shown in  FIGS. 1 and 2 , the backpack type bag with a self-balancing electric vehicle mounted thereon according to the present invention includes a support rod  20  serving as a frame of the invention during riding and the handle  21  mounted on the top portion of the support rod  20  in such a manner as to be drawn and taken by the rider. 
     As shown in  FIG. 2 , the support rod  20  has a housing  30  mounted on one side thereof, and the housing  30  has batteries mounted in the interior thereof to supply power to motors  51  mounted on the wheels  50  and a controller  31  mounted on the underside thereof, in which a variety of sensors inclusive of a Gyro sensor are located. Further, as shown in  FIGS. 5 and 6 , the housing  30  is located inside the backpack type bag  10  and serves as a bottom plate supporting items when the items are put into the backpack type bag  10 . 
       FIGS. 3   a  and  3   b  are perspective views showing wheels of the backpack type bag according to the present invention, and  FIG. 4  is a perspective view showing the assembled state of the parts of the frame in the backpack type bag according to the present invention. As shown in  FIG. 3   a , each wheel  50  has the motor  51  mounted thereon to activate the corresponding wheel, and each motor  51  has a foot board  40  firmly mounted on the top surface thereof, on which the rider&#39;s foot is placed. After that, the support rod  20  as shown in  FIG. 2  is fixed rigidly to the top surfaces of the two foot boards  40  by means of welding or fixing means like bolts, thereby finishing the frame of the backpack type bag according to the present invention, as shown in  FIG. 4 . 
     Accordingly, the user is placed on the foot boards  40 , and next, if his body is inclined forward by a given angle, the variety of sensors inclusive of the Gyro sensor sense the inclination of the rider&#39;s body, thereby allowing the motors  51  to be operated by a degree where the inclination is removed. At this time, the wheels  50  are activated in the direction toward which the rider&#39;s body has been inclined through the operation of the motors  51 , so that safe riding is achieved, while the balancing operation of the self-balancing electric vehicle is being maintained to the upright riding position. 
       FIG. 5  is a separate perspective view showing the backpack type bag separated from the frame, and as shown in  FIG. 5 , the backpack type bag  10  is mounted onto the frame on which the self-balancing electric vehicle is fixedly disposed in such a manner as to encompass the support rod  20  and the housing  30 , thereby completing the manufacturing of the backpack type bag with the self-balancing electric vehicle mounted thereon as shown in  FIG. 6 . 
     As set forth in the foregoing, according to the present invention, the backpack type bag with the self-balancing electric vehicle mounted thereon serves as means for moving people or their items, thereby providing many conveniences in use to the rider. That is, in the process where the user carries the backpack type bag  10  into which items are put on his shoulders and moves to his destination, if he reaches a good place for riding, he puts the backpack type bag  10  on the ground to draw the handle  21  from the support rod  20 . Next, he stands on the foot boards  40  and rides with the inclination of his body, and by the way, if there are stairs or severely inclined places bad for riding, or if he should take the subway or bus, the backpack type bag  10  is carried again on his shoulders, thereby allowing him to keep walking Accordingly, it is very convenient to move personal&#39;s items or people.
