Lifting mechanism and lifting floor and automobile using the lifting mechanism

Abstract

The invention discloses a lifting mechanism, a lifting floor and an automobile using the lifting mechanism. The bottom of the lifting frame of the lifting mechanism is hinged with more than two swing arms arranged at intervals. The upper end of the swing arm is the movable end hinged on the lifting frame, and the lower end is used to be directly hinged on the car body or fixed on the car body. The fixed end on the floor fixing frame is hinged, and the hinge axes of the moving and fixed ends of each swing arm are parallel to each other. In this way, after the lifting frame is lowered, the swing arm will be retracted along with the lowering of the lifting frame, and when the lifting frame needs to be raised to a higher height, the length of the swing arm will be correspondingly lengthened. The arm will still be folded, so that after the lifting frame is lowered, the swing arm will not increase the distance between the lifting frame and the car body, so that the volume of the entire lifting mechanism will not increase, thereby ensuring that the lifting floor is on the ground. It takes up less space after the floor is dropped.

Description

technical field [0001] The invention relates to a lifting mechanism, a lifting floor and an automobile using the lifting mechanism. Background technique [0002] With the improvement of people's living standards, tourism has become one of people's leisure ways after work, and caravans have attracted more and more attention. At present, some self-propelled caravans produced at home and abroad have been equipped with telescopic cabin mechanisms, but most of the telescopic cabins are located on the floor of the car, which restricts the height of the telescopic cabin. After the telescopic cabin, the floor of the telescopic cabin is not on the same plane as the interior floor of the car, which is not beautiful and cannot make full use of the space in the car. Therefore, more and more travel enthusiasts hope that the floor of the telescopic cabin and the interior floor of the car will be on the same plane when the telescopic capsule is retracted. Plane, when the telescopic cabin ...

Problems solved by technology

However, limited by the cooperation between the wedge block and the roller in the wedge-shaped sliding mechanism, the greater the lifting height required for the lifting frame, the higher the height of the wedge block, and the larger the volume of the corresponding wedge block. When the floor is in a falling state, the volume of the lifting mechanism is relatively large, and the output power of the electric push rod during the lifting process of the floor will be increased, so that the entire lifting floor takes up a large space and consumes too much energy.

In addition, between the lifting frame and the horizontal sliding frame, the lifting frame is assembled on the horizontal sliding frame and the fixed floor frame by the rolling fit of the wedge-shaped sliding mechanism and the vertical sliding mechanism, that is, the lifting frame is installed on the fixed floor frame by its own weight. And on the horizontal sliding frame, so that when the vehicle encounters a turn, travels on an uneven road surface, goes up and down, etc., the lifting frame will move up and down relative to the fixed floor frame, so that on the one hand, it will cause the lifting frame to move up and down. Larger noise affects the comfort of passengers in the car; on the other hand, due to the overall weight of the lifting frame and the upper fixed surface plate is relatively large, the center of gravity of the whole vehicle will also change accordingly after the lifting frame goes up. Changes, especially when the vehicle is turning, the center of gravity of the vehicle will shift to the lower side of the body, which will make the body easy to roll over and reduce the safety of driving
