Crash Bracket

Abstract

An anticollision support is installed at the bottom of a stand column of an intelligent stair lift chair and comprises a fixing plate, a movable base plate, safety switches, switch striking plates, collision blocks and a tension spring. The movable base plate is installed on the fixing plate and can slide on the fixing plate in the vertical direction in a limited mode. The safety switches comprise the left safety switch and the right safety switch, the left safety switch is installed on the fixing plate and located on the left side of the movable base plate, and the right safety switch is installed on the fixing plate and located on the right side of the movable base plate. The switch striking plates comprise the left switch striking plate and the right switch striking plate which are positioned on the movable base plate and can rotate on the movable base plate around a shaft. The collision blocks are located between the left safety switch and the right safety switch in the left and right direction and comprise the left collision block connected to the left switch striking plate and the right collision block connected to the right switch striking plate. The tension spring connects the left collision block with the right collision block. The anticollision support can prevent collision in multiple directions.

Description

technical field [0001] The invention relates to an anti-collision support, in particular to an anti-collision support for an intelligent stair lift chair. Background technique [0002] At present, the anti-collision bracket used for intelligent stair lift chairs directly touches the safety switch by the touch wedge, and the switch is turned on and off within a certain stroke, so that the identification signal system can notify the moving parts of the imminent situation as early as possible, in order to prevent the danger of collision , the management system can issue an order to stop the movement in time. The general anti-collision mechanism has only one safety switch, which can only control the anti-collision of one-way movement. For the multi-degree-of-freedom movement device, it is necessary to install multiple groups of anti-collision mechanisms to realize the multi-directional anti-collision function, resulting in a complex structure. Difficult to install. [0003] It...

Problems solved by technology

The general anti-collision mechanism has only one safety switch, which can only control the anti-collision of one-way movement. For the multi-degree-of-freedom movement device, it is necessary to install multiple groups of anti-collision mechanisms to realize the multi-directional anti-collision function, resulting in a complex structure. difficult to install

[0003] It can be seen that the above-mentioned existing anti-collision support for the intelligent stair lift chair still has many defects, and it needs to be improved.
