MODE FOR INVENTION

(8) Hereinafter, an explanation on a backpack type self balancing scooter having a foot-driven steering apparatus mounted thereon according to the present invention will be in detail given with reference to the attached drawing.

(9) According to the present invention, a backpack type self balancing scooter having a foot-driven steering apparatus mounted thereon is characterized in that a dialing type shuttle ring on which a rider's foot is stepped is turned to conduct the direction changes of the scooter, so that his or her both hands are freely used while the scooter is being driven. While the backpack type self balancing scooter is being not driven, it can be carried on his or her back, thus optimizing the conveniences in the transportation and storage thereof.

(10) FIG. 2 is an exploded perspective view showing a backpack type self balancing scooter having a foot-driven steering apparatus mounted thereon according to the present invention, and FIGS. 3 and 4 are perspective views showing a motor housing and a footrest of the backpack type self balancing scooter according to the present invention. As shown in FIGS. 2 and 3, a backpack type self balancing scooter having a foot-driven steering apparatus mounted thereon according to the present invention has two motors 21, two wheels 20 mounted on the shafts of the motors 21, and a motor housing 10 for mounting the two motors 21 therein in such a manner as to allow rotary shafts of the motors 21 to be located linearly to each other.

(11) Further, a footrest 30 is disposed on top of the motor housing 10 to place a rider's feet thereon. The footrest 30 desirably includes concave and convex portions or a non-slip material formed thereon to generate a frictional force from the soles of the rider's feet, so that he or she can take a stable posture.

(12) On the other hand, the footrest 30 has a mounting hole 31 formed on any one side thereof to mount a shuttle ring 40 as will be discussed later thereon in such a manner as to be rotatingly operated in a dialing way. The mounting hole 31 on which the shuttle ring 40 is mounted is desirably formed at a position where the rider's foot is naturally placed on the top of the mounting hole 31 in the state where his or her feet are open at a shoulder width.

(13) The shuttle ring 40 is turned to left and right sides to manipulate the direction changes of the self balancing scooter according to the present invention. That is, the shuttle ring 40 is turned through the compression force applied from the rider's foot stepped thereon to conduct left turning or right turning, and if the direction change is finished, the application of the compression force is naturally released to automatically return the turned shuttle ring 40 to its original position. FIG. 4 is a perspective view showing the motor housing 10, the motors 21, the wheels 20, the footrest 30 and the shuttle ring 40 mounted on the self balancing scooter according to the present invention.

(14) FIG. 5 is a perspective view showing an erecting housing of the backpack type self balancing scooter according to the present invention. As shown in FIGS. 1 and 5, an erecting housing 50 is located on top of the footrest 30 and has a battery 51 mounted therein to drive the motors 21. Further, the erecting housing 50 has a power applying switch, a plug for charging the battery 51, and a display for displaying the driving state, the rest amount of the battery 51 and malfunctions, mounted on one side surface thereof.

(15) On the other hand, as shown in FIG. 5, the erecting housing 50 has a controller 52 mounted on the upper portion thereof, on which a variety of sensors like a gyro sensor are collected, to control driving and direction changes of the self balancing scooter, and a cover 53 disposed coveringly on top thereof. A saddle 60 whose height is adjustable is insertedly fitted to an insertion hole 54 formed on the center of the cover 53.

(16) FIG. 6 is a perspective view showing a partially coupled state of the backpack type self balancing scooter according to the present invention. As shown in FIG. 6, if the erecting housing 50 is mounted on top of the footrest 30, the rider's feet are placed on the footrest 30 in the state where he or she sits on the saddle 60, and his or her body is inclined forwardly or backwardly to drive the scooter, while his or her both hands are being freely used.

(17) As described above, the backpack type self balancing scooter according to the present invention is configured wherein the shuttle ring 40 on which the rider's foot is stepped is compressed and rotated to a left or right side to conduct the direction change of the scooter while driven, so that the direction change signal of the shuttle ring 40 is transmitted along an electric wire to the controller 52 mounted in the erecting housing 50, thus allowing the self balancing scooter to be changed in direction.

(18) FIG. 7 is a perspective view showing the use state of the backpack type self balancing scooter according to the present invention. As shown in FIG. 7, a backpack 80 is mounted surroundingly on the erecting housing 50, thus completely providing the backpack type self balancing scooter according to the present invention. On the other hand, the saddle 60 may press upon the rider's head when the self balancing scooter according to the present invention is carried to the shape of the backpack 80 on his or her back, and therefore, the saddle 60 is desirably turned in the direction of an arrow as shown in FIG. 7.

(19) Accordingly, the backpack type self balancing scooter having a foot-driven steering apparatus mounted thereon according to the present invention is capable of providing an individual's personnel transportation means, thus giving many conveniences in the transportation and storage to the individual. That is, during the rider moves to his or her destination in the state of carrying the backpack 80 on his or her back, he or she puts the backpack 80 on the ground, steps on the footrest 30, sits on the saddle 60, and inclines his or her body to drive his or her scooter on a place where driving is convenient, but on stairs or sharp slopes on which driving is hard or on subway or bus boarding, he or she carries the backpack 80 on his or her back again, thus allowing the individual's objects and scooter to be transported and stored in a very convenient way.

(20) Further, the backpack type self balancing scooter according to the present invention is capable of allowing the rider's both hands to be freely used in the state of riding thereon. Accordingly, his or her both hands are freely used so that during driving, he or she can take photos, hold objects, or do something. On the other hand, even if the rider has disabilities in hands, he or she can drive the scooter with the manipulation of the shuttle ring 40 through his or her foot, so that the self balancing scooter can be foot-driven easily.

(21) While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
