The invention discloses a getting-on step for a special vehicle model, which comprises two fixed supports, a connecting rod component and a locking structure, the two ends of the connecting rod component are respectively hinged with the two fixed supports, and the two fixed supports are arranged at the bottom of a skirt of a vehicle body at an interval; the connecting rod assembly has a first state for stepping when unfolded and a second state for being hidden to the bottom of the skirt edge of the vehicle body to pass through an uneven road surface when folded, and the locking mechanism comprises convex parts fixed to the two ends of the connecting rod assembly correspondingly and concave parts located at the ends, close to the connecting rod assembly, of the two fixing supports correspondingly. And the convex part and the concave part in one corresponding group are inserted in a matched manner, so that the connecting rod assembly is prevented from rotating around the fixed bracket when being in the first state.
本发明公开一种特种车型用上车踏步,包括两个固定支架、两端分别与两个固定支架铰接的连杆组件及锁止结构,两个固定支架间隔设置于车体裙边底部,连杆组件具有展开时用于踏步的第一状态和收纳时隐藏至所述车体裙边底部以便于通过不平路面的第二状态,锁止机构包括分别固定于所述连杆组件两端的凸部和分别位于两个所述固定支架靠近所述连杆组件一端的凹部,相对应一组的所述凸部和凹部配合插接,以防止所述连杆组件在处于所述第一状态时围绕所述固定支架转动。
