A balance wheel fixing mechanism and a balance vehicle according to an embodiment of the present invention will be described below with reference to FIGS. 1 through 6.

The fixing mechanism 23 is provided with a fixing member 23 and a connecting member 24; the fixing member 23 is fixedly disposed at the bottom of the recess 22; One end of the connecting member 24 is movably connected to the fixing member 23; the other end is movably connected to the wheel shaft 31 of the wheel 30; and the recess 22 has a receiving space for the connecting member 24 on both sides of the fixing member 23.

The connecting member 24 has a symmetrical structure, and two ends are respectively provided with notches. The notches are respectively provided with a rotating shaft 25; the fixing member 23 is embedded in the notch, and the fixing member 23 is provided with a through hole that cooperates with the rotating shaft 25. The symmetrical structure prevents reverse connection during production.

The axle 31 member includes a shaft body 32. One end of the shaft body 32 is provided with an adapter portion; and the opposite side of the adapter portion from the shaft body 32 is provided with a support portion 34 movably coupled to the connector member 24. The support portion 34 is embedded in the notch, and the fixing member 23 is provided with a through hole that cooperates with the rotating shaft 25. In general, the axles 31 are relatively thin, and it is not easy to realize a rotatable fixing structure. The contact portion can increase the contact area of the rotating shaft 25, and on the one hand, it is easy to be fixed with the connecting member 24, and on the other hand, the wheel is deployed. Positioning in contact with the side of the vehicle body 20 improves stability when the wheel 30 is in operation.

The adapter portion is a circular table 33; the support portion 34 is fixed at a position where the circular table 33 is offset from the axis. The support portion 34 is offset from the axis. When the balance vehicle is in operation, the support portion 34 naturally runs to the lowest point due to gravity and human body pressure, forming a steady-state positioning structure. At this time, the disc portion above the support portion 34 has More area is in contact with the side of the vehicle body 20, so that the wheel 30 is positioned in the vertical direction by the disk, and the horizontal position is supported by the bottom connecting member 24. The double-sided support can effectively disperse the bearing weight of the wheel 30, and is more stable and durable.

A slit 26 for accommodating the circular table 33 is provided at the tail of the recess 22. Thus, in the folded state of the wheel 30, the disk can be inserted into the slit 26 to reduce the overall thickness.

Optionally, the balance car further includes a vehicle pole 10 for controlling the steering of the balance vehicle; the vehicle pole 10 includes a fixed rod 11 movably coupled to the vehicle body 20, a connecting rod 12 rotatably coupled to the fixed rod 11; and the connecting rod 12 is rotated The connecting support rod 13; when in the fully folded state, the end of the support rod 13 is in contact with the vehicle body 20. This structure allows the lever 10 to lie down to achieve the function of leg control.

The connecting rod 12 has a flat shape. The connecting rod 12 is placed horizontally and has a flat shape for use as a stool.

The top 15 of the support rod 13 is a curved surface; the body 20 is provided with a recess 21 that cooperates with the curved surface; and the top 15 is provided with a foldable handle 16 on both sides. This can ensure that the axle 10 can maintain effective support in the folded state, and can ensure the flexible rotation of the axle 10 and better leg control.

The fixed rod 11 includes a first rod 17 movably coupled to the vehicle body 20, and a second rod 18 that is telescopically nested within the first rod 17; the connecting rod 12 is rotatably coupled to the top end of the second rod 18. In order to realize the leg control, it is better to ensure that the height of the connecting rod 12 exceeds the height of the human knee in the folded state, and the fixing rod 11 can be extended and contracted, which can be conveniently used by people of different heights.

Of course, the wheel 30 fixing structure of the present invention can also be applied to a car without a lever, which is rotated by a left and right pedal.

The above is a further detailed description of the present invention in connection with the specific preferred embodiments, and the specific embodiments of the present invention are not limited to the description. It will be apparent to those skilled in the art that the present invention may be made without departing from the spirit and scope of the invention.
