A balance car body structure and a balance car according to an embodiment of the present invention will be described below with reference to FIGS. 1 through 6.

The structure of the balance car body 20 of the present embodiment includes two car bodies 20, and the connecting shaft 10 is disposed directly below the joint of the two car bodies 20; the car body 20 is provided with wheels 30 at one end away from the seam; The vehicle body 20 is provided with a bracket 11 connected to the connecting shaft 10; the frame is movably connected to the connecting shaft 10.

Each of the vehicle bodies 20 is provided with two brackets 11, and the brackets 11 between the two vehicle bodies 20 are staggered. The staggered arrangement ensures the symmetry of the two bodies 20, reduces the post-production and processing costs, and also improves the stability of the body 20 along the axial direction. Of course, the arrangement between the brackets 11 can have other indications, such as the two brackets 11 of one body 20 being inside; the other brackets 11 of the other body 20 are outside.

A sleeve 13 is disposed in the middle of the connecting shaft 10; the bracket 11 is fixed at both ends of the sleeve 13. The technical solution adds a sleeve 13 at the rotating shaft 25, which can restrict the translation of the bracket 11 on the rotating shaft 25, and can also be folded. Easy to carry.

The bracket 11 includes a fixing post 14 fixed perpendicularly to the vehicle body 20, and a connecting post 15 connected to the fixing post 14; the connecting post 15 is provided with a through hole movably connected with the connecting shaft 10; the connecting post 15 and the fixing post 14 The angle is an obtuse angle; the side of the fixing post 14 is flush with the end surface of the vehicle body 20. This is a specific structure of the bracket 11, which is firstly extended to the bottom of the vehicle body 20 by the vertically fixed fixing column 14, and then connected to the rotating shaft 25 through the inclined connecting column 15, so that the two opposite bodies 20 can be effectively reduced. The overlapping area between the brackets 11 reduces the interference between the brackets 11 and makes the vehicle body 20 more flexible when it is rotated.

Optionally, the bottom of the vehicle body 20 is further provided with a recess 22, and the recess 22 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; The other end is movably connected to the axle 31 of the wheel 30; the recess 22 has a receiving space for the connecting member 24 on both sides of the fixing member 23. The technical solution adopts the connecting member 24 to connect the axle 31, and the connecting member 24 itself can also rotate around the fixing member 23 in the groove 22. The rotatable structure at both ends can ensure that the wheel 30 can be completely stored in the vehicle body 20 in the folded state. At the bottom, the storage area of the balance car in the folded state of the wheel 30 is further reduced. The presence of the recess 22 reduces the thickness of the vehicle in the folded state of the wheel 30. In this way, the wheel 30 and the vehicle body 20 can be folded to further improve the folding effect of the entire vehicle.

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, and when the balance vehicle is in operation, the support portion 34 is affected by gravity and human body pressure. It will naturally run to the lowest point to form a steady-state positioning structure. At this time, the disk portion above the support portion 34 has more area to be in contact with the side of the vehicle body 20, so that the wheel 30 has a disk in the vertical direction, and the horizontal position has The bottom connecting member 24 is supported, and the double-sided support can effectively disperse the bearing capacity of the wheel 30, and is more stable and durable.

The recess 22 of the recess 22 is provided with a slit 26 for receiving the circular table 33. Thus, in the folded state of the wheel 30, the disk can be inserted into the slit 26 to reduce the overall thickness.

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.
