Simply turning the steering wheel left or right allows for forward and backward movement. These cars can be played by either single or multiple players, fostering learning and teamwork. Because the car is low to the ground, it's also relatively safe.

[0027] The electric toy car of the present invention comprises a car body, wherein the car body is provided with a running mechanism capable of twisting and running.

[0028] See also Figure 1The twistable walking mechanism includes a steering rod group, an axle 1, a wheel group 11, a one-way transmission mechanism and a power input mechanism. The steering rod group includes a steering wheel 2 and a steering rod 3 fixedly arranged below the steering wheel. The lower end of the steering rod is fixedly connected to the middle part of the axle, and a wheel group is provided at both ends of the axle. The one-way transmission mechanism includes a first connecting member and a second connecting member that can rotate relatively in one direction. The first connecting member and the wheel axle are fixedly connected in an integral or split manner, or the first connecting member is a part of the rod body of the wheel axle, the second connecting member is fixedly connected to the wheel group, and the wheel group and / or the second connecting member are transmission-connected to the power input mechanism.

[0029] Figure 1 In the embodiment, the one-way transmission mechanism includes a one-way bearing 4, the first connecting member is the inner ring 5 of the one-way bearing, the second connecting member is the outer ring 6 of the one-way bearing, and the outer ring is fixedly connected to the wheel set through a third connecting member, wherein the third connecting member is a bearing sleeve 7 mounted on the outer ring. In other embodiments, the third connecting member can also be a rod or other suitable structure.

[0030] The power input mechanism is drivingly connected to the third connecting member and includes a power output gear 8. The third connecting member is provided with teeth that mesh with teeth on the power output gear. Specifically, the power input mechanism includes a drive motor 9 and a gearbox 10 connected to the output end of the drive motor for speed change. The power output gear is disposed in the gearbox.

[0032] The electric toy car of this embodiment can be switched freely between the electric mode and the twisting mode.

[0033] In electric mode: turn on the start switch on the electric toy car, drive motor 9 to work, the power output gear 8 of the gear box 10 drives the bearing sleeve 7 to rotate, and the bearing sleeve 7 drives the wheel set 11 to rotate forward.

[0034] After the driving motor 9 stops working, the power input mechanism has no power output and enters the twisting mode.
