FIG. 2 is a schematic view of the structure of the elastic connecting member;
fig. 3 is a schematic view of a connection structure between two lower vehicle bodies.
Detailed Description
The present invention will be further described with reference to the following examples.
The double-wheel balance vehicle shown in fig. 1-3 comprises a left vehicle body and a right vehicle body, wherein the left vehicle body comprises an upper left vehicle body 1 and a lower left vehicle body 2, the right vehicle body comprises an upper right vehicle body 3 and a lower right vehicle body 4, a left shaft hole 16 and a right shaft hole 17 are respectively arranged on the left vehicle body and the right vehicle body, a hollow connecting shaft 5 is connected between the lower left vehicle body 2 and the lower right vehicle body 4, the connecting shaft penetrates through the left shaft hole and the right shaft hole, a battery 6, a self-balancing control device 7 and an electric driving device are further arranged in the left vehicle body or the right vehicle body, wheels 8 are symmetrically arranged on two sides of the vehicle body, the wheels 8 are connected with a hub motor, and the battery 6, the self-balancing control device 7, the electric driving device, the wheels 8 and the hub are all in the prior art, and detailed description is not. The left upper vehicle body 1 is connected with a left pedal 9, and the right upper vehicle body 3 is connected with a right pedal 10. The left upper bicycle body 1 is connected with a left pedal leather 11, and the right upper bicycle body 3 is connected with a right pedal leather 12. The left pedal 9, the right pedal 10, the left pedal leather 11 and the right pedal leather 12 are all prior art and are not explained in more detail here.
It should be noted that in this embodiment, the connecting shaft 5 is rotatably engaged with both the left vehicle body and the right vehicle body, and an elastic connecting member 13 is disposed in the connecting shaft 5 and penetrates through the connecting shaft 5, and two ends of the elastic connecting member 13 are respectively fixed to the left vehicle body and the right vehicle body. The two car bodies can twist and deform the elastic connecting piece 13 after rotating a certain angle, and the elastic connecting piece 13 has elasticity, so that a user can be assisted to keep the two car bodies on the same plane through the elastic restoring force of the elastic connecting piece 13. When the balance car is not used, the two car bodies are also in the same plane.
In order to enable the elastic connecting element 13 to generate a torsional elastic restoring force, the elastic connecting element 13 is designed as a spring steel sheet. The elastic connecting piece 13 is formed by overlapping a plurality of sheet-shaped spring steel sheets. The multi-spring steel sheet is good in flexibility and capable of increasing elastic restoring force.
It is further noted that, in order to prevent the abrasion of the vehicle body, the connecting shaft 5 and the left and right shaft holes are respectively provided with a sleeve 14, and the connecting shaft 5 rotates relative to the sleeve 14. Barrel casing 14 in this embodiment adopts the copper product to make, and barrel casing 14 described in this embodiment tight fit respectively is in left shaft hole and right shaft hole. The sleeve 14 and the vehicle body can be made into an integral structure during injection molding, so that the tight fit effect of the sleeve and the vehicle body can be improved.
