    • The present invention relates to an inline skate, and more particularly, to an inline skate including a wheel-driving unit which generates power when a foot pushes on the ground to rotate the wheels, and when the boot is lifted, the frame is spaced apart from the ground to further increase the time required for stepping forward on the ground or being pushed from the ground, thereby obtaining propulsive force such that the inline skate quickly advances. To this end, the inline skate including the wheel-driving unit according to the present invention includes a boot, as well as a frame, on which a plurality of wheels are installed, on the bottom surface of the boot. One side end of the bottom surface of the boot is hingedly coupled to the upper end of the frame. One end of a link is hingedly coupled to the other side of the bottom surface of the boot. A driving gear is disposed on one end of the frame. A connection gear is coaxially disposed on one wheel of the plurality of wheels installed on the frame, and is engaged with the driving gear to thereby be rotated. A driving unit for rotating the driving gear is disposed on the other end of the link.
    • 更具体地说,本发明涉及一种直排轮溜冰鞋,更具体地说,涉及一种直排轮溜冰鞋,包括一脚轮驱动单元,该踏板驱动单元当脚踏地面旋转车轮时产生动力,并且当提升靴子时,框架间隔开 从地面上进一步增加在地面上向前推进或被迫从地面推进所需的时间,从而获得推进力,使内联滑冰迅速前进。 为此,包括根据本发明的车轮驱动单元的直排轮滑在底盘的底面上包括一个其上安装有多个车轮的车罩以及框架。 护罩的底表面的一侧端部铰接地联接到框架的上端。 连杆的一端铰链地连接到底架的底表面的另一侧。 驱动齿轮设置在框架的一端。 连接齿轮同轴地设置在安装在框架上的多个车轮的一个车轮上,并与驱动齿轮啮合从而被转动。 用于旋转驱动齿轮的驱动单元设置在连杆的另一端。
