Hereinafter, an eighth embodiment of a wheel control apparatus capable of decelerating or braking a wheel according to a change in a road slope according to the present invention will be described. FIG. 11 is a view illustrating an eighth embodiment of a wheel control apparatus capable of decelerating or braking a wheel according to a change in a road slope according to the present invention.

Referring to FIG. 11, an eighth embodiment of the present invention includes a locking part 602 having an upper end fixedly coupled to a lower end of the fixing frame 100, and a lower end having a long hole 601 which forms a front upward inclined surface; And a connecting bar 603 having one end pinned to a lower portion of the fluid 210 and the other end movably inserted into the long hole 601, wherein the connecting bar 603 is connected to the long hole 601. It is characterized in that the rotation of the fluid 210 is prevented while being located in the inclined surface of the).

Since the human walking motion is not a constant velocity motion, even if the flat road flow control unit 200 is a pendulum motion steadily in accordance with the gait step, the deceleration plate 220 is in contact with the inner peripheral surface of the wheel 11 at the moment. Such instantaneous contact does not operate the wheel control device, but it is preferable that the momentary contact is formed by forming a locking part 602 having a long hole 601 having a predetermined inclined surface and connecting the fluid 210 to the instantaneous contact.

For example, if the long hole 601 having an inclined surface of 40 degrees and 6 degrees is configured, the flow control unit 200 must first climb up a steep inclination of 40 degrees in contact with the inner circumferential surface on a flat surface. Overcoming the 40-degree slope is relatively laborious. Once the car has climbed over 40 degrees, the fluid 210 continues to be pushed back because there is a slope of 6 degrees again.

If the device equipped with the wheel control device (for example, a baby carriage) according to the eighth embodiment of the present invention enters the inclination of 15 degrees, the inclination to be overcome initially is reduced to 40 degrees-15 degrees = 25 degrees, The inclination is a downhill inclination of 6 degrees-15 degrees = -9 degrees to push the flow control unit 200 toward the inner circumferential surface of the wheel (11). Therefore, the locking portion 602 having the long hole 601 having such a constant inclined surface prevents contact on the flat, but does not interfere with the contact on the downhill.

As shown in FIG. 11, the locking part 602 having the long hole 601 having the inclined surface is preferably configured at two angles of inclination, but may function as an angle, that is, a long hole composed of one inclined surface. Can be.
