The second difference between the platform vehicle of this embodiment and the first embodiment is the control of the steering of the platform vehicle. In the process of using the platform vehicle, most of the time it walks in a straight line and does not need to be turned. Therefore, the wheel 61 is set as a fixed wheel, and the fixed wheel includes a driving wheel and a driven wheel, and the driving wheel is driven by a driving motor to travel. In this embodiment, the steering mechanism is set corresponding to the driven wheel.

Specifically: in this embodiment, a handlebar 62 , a handlebar shaft 63 , a steering column 64 and a steering mechanism are further provided on the fixing frame 1 . The handlebar 62 is fixedly connected to the handlebar shaft 63, and the handlebar 62 is arranged between the first lifting platform 2 and the second lifting platform 3, and the specific location is suitable for the convenience of the staff to operate. A bump 631 is provided on the side of the handlebar shaft 63 . Specifically, at the bottom end of the handlebar shaft 63, a number of projections are arranged around its side. The steering column 64 is connected to the passive wheel 61 through a steering mechanism.

There are two steering arms 65 , and the two steering arms 65 are horizontally fixed to the wheel shaft 67 respectively. The tie rod 66 is disposed between the two steering arms 65 , and two ends of the tie rod 66 are hinged to the two steering arms 65 respectively. The steering vertical rod 64 is vertically fixed on the tie rod 66 . In this way, the handlebar drives the steering column 64 to rotate, and the steering column 64 drives the two steering arms 65 to rotate left and right, thereby driving the wheels 61 to rotate.

When the platform vehicle of this embodiment is in use, the controller controls the drive motor to drive the driving wheel to rotate, and the platform vehicle walks straight.

The handlebar 62 can be lifted by the staff by pulling the handlebar 62 . When you need to steer, you just need to lift the handlebar to the highest position, then turn the handlebar, and the platform truck can be steered.

The above-mentioned embodiments only represent several embodiments of the present utility model, and the descriptions thereof are specific and detailed, but should not be construed as a limitation on the scope of the utility model patent. It should be pointed out that for those of ordinary skill in the art, some modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
