Stable supporting type electric stair-climbing van

Abstract

The invention discloses a stable supporting type electric stair climbing van which comprises a walking mechanism, a bearing mechanism, an electric push rod, a battery pack and a controller, the bearing mechanism is installed on the walking mechanism, a bottom frame of the walking mechanism is provided with an obtuse angle structure, and the bottom frame is provided with a first hinge plate; the bearing mechanism comprises a horizontal frame, a vertical frame, a fixed frame, an extension frame and a holding rod, a second hinge plate is arranged on the horizontal frame and hinged to the first hinge plate through a hinge column, a bearing plate is installed on the horizontal frame, and the lower end of the bearing plate abuts against a plurality of gaskets of the horizontal part of the bottomframe; the horizontal frame is connected with the bottom frame via the electric push rod, in the stair climbing process of the stair climbing van, the bearing plate is adjusted to be in the horizontal state relative to the ground from the inclined state by adjusting the electric push rod, goods are in the horizontal state, the situation that the goods are located on the bearing plate in the inclined state is avoided, and the goods can be prevented from sliding down when in the inclined state; and stable supporting of the goods during stair climbing of the van is achieved.

Description

technical field [0001] The invention relates to the technical field of trucks, in particular to a stable support type electric stairs-climbing truck. Background technique [0002] In family life, it is often necessary to carry some heavy objects upstairs and downstairs. Manual transportation is very laborious. Therefore, electric stair climbing trucks are needed. The existing electric stair climbing trucks are generally relatively simple, and there are certain limitations. insufficient. [0003] Ordinary electric stair-climbing trucks have a simple structure, and cannot provide fixed support for heavy objects of different sizes during use. Especially when the stair-climbing truck is transformed from a horizontal moving state to a stair-climbing state, due to the change of operating posture, the cargo will be damaged. It is easy to shake, the support stability is insufficient, and the risk is high. When going downstairs, the electric stair-climbing truck may move down quickl...

[0002] In family life, it is often necessary to carry some heavy objects upstairs and downstairs, and manual transportation is very laborious. Therefore, electric stair climbing trucks are needed. The existing electric stair climbing trucks are generally relatively simple, and there are certain limitations. insufficient

[0003] Ordinary electric stair-climbing trucks have a simple structure, and cannot provide fixed support for heavy objects of different sizes during use. Especially when the stair-climbing truck is transformed from a horizontal moving state to a stair-climbing state, due to the change of operating posture, the cargo will be damaged. It is easy to shake, the support stability is insufficient, and the risk is high. When going downstairs, due to the inertia, the electric stair-climbing truck may move down quickly, resulting in loss of control, so there is also a high risk
