Wherein, the support wheel of the embodiment can also be contracted onto the vehicle body, for example:

As shown in FIGS. 5 and 6, when the telescopic member is retracted into the telescopic cavity, the support wheel can be retracted onto the vehicle body. When the user does not need to transport or carry the article, the rotating plate can be rotated to the upper side of the vehicle body, and the telescopic member is contracted into the telescopic cavity of the vehicle body, so that the supporting wheel is still located outside the vehicle body, and can follow the electric balance car Movement and rotation, due to the role of the support wheel, increases the friction and resistance of the electric balance car. In this embodiment, the support wheel can be contracted to the vehicle body, so that the support wheel does not follow the movement of the electric balance car, so that the user can use the electric balance car to travel.

Specifically, the support wheel 300 is fixedly connected by a support rod 310 and a driving rod 212 of the telescopic member 210. The support rod and the driving rod are fixedly connected by a support pin, and the support rod is rotatable along the support pin. The bottom of the vehicle body 110 is provided with a card slot 112. The support wheel 300 is provided with a post 320 for being placed into the card slot 112. When the post is placed into the card slot, the support wheel is shrunk. To the bottom of the car body.

More specifically, the support wheel is provided with an axle, and the post is a portion extending outwardly from the end of the axle, and the post is formed by two outward extensions respectively through the two ends of the axle. There are also two corresponding card slots 112. Specifically, the bottom of the vehicle body is provided with a sheet-shaped card board, and the card board is two, which are disposed adjacent to each other, and the card slot is disposed on the card board.

A first connecting rod 330 is fixedly connected to the two sides of the supporting rod, and one end of the first connecting rod is rotatably connected to the supporting rod, and the other end of the first connecting rod is rotatably connected with the second connecting rod 340 The second link is rotatably coupled to the telescopic member. Specifically, the second link 340 is rotatably coupled to the connecting piece 113, and the connecting piece is disposed on the driving rod of the telescopic member.

When the support wheel is contracted, the force is applied to the joint portion of the first link and the second link, so that the first link and the second link rotate with each other, thereby driving the support rod to rotate along the support pin, and shrinking the telescopic member Into the telescopic cavity, the post on the support wheel can be placed into the card slot, so that the support wheel can be stored in the bottom of the vehicle body to prevent the support wheel from rotating, so that the user can use the electric balance car to travel.

When the telescopic member is stretched, the telescopic member is pulled out from the telescopic cavity, and the support wheel is pulled out, so that the first The connecting rod and the second connecting rod rotate with each other, and the first connecting rod and the second connecting rod are gradually straightened, so that the interaction between the first connecting rod and the second connecting rod plays a role of supporting and positioning the supporting rod. Prevent the support wheel from rotating with the support pin.

In this embodiment, the support wheel is further provided with a brake pad.

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.
