Door opening limit mechanism, door panel assembly and armored vehicle
The invention relates to the technical field of limit devices, in particular to a door opening limit mechanism. The mechanism comprises a fixing seat, a pull arm, a sliding shaft, a sliding shaft mounting seat and a transmission device, the pull arm is hinged to the fixing seat, a sliding groove is formed in the pull arm, a limit groove is formed in the sliding groove, the sliding shaft is connected with a door panel assembly through the sliding shaft mounting seat, the sliding shaft can slide along the sliding groove, the sliding shaft is connected with a following cam sleeve, the cam sleeveis arranged inside the sliding groove, a cam limit block on the cam sleeve can enter and exit from the limit groove, the sliding shaft is also connected with a rotating execution device, the transmission device drives the sliding shaft to rotate through the rotating execution device, and the sliding shaft is further connected with a pre-tensioner. The invention further provides the door panel assembly provided with the door opening limit mechanism and an armored vehicle. Compared with the prior art, the door opening limit mechanism has the beneficial effects that the door opening limit mechanism can well limit the door panel assembly, and an operator can conveniently limit, position and release the door panel assembly.
本发明涉及限位装置技术领域，具体涉及一种开门限位机构，其包括固定座、拉臂、滑动轴、滑动轴安装座和传动装置，拉臂与固定座铰接，拉臂上设有滑槽，滑槽内设置有限位槽，滑动轴通过滑动轴安装座与门板总成连接，滑动轴能够沿滑槽滑动，滑动轴上连接有随动的凸轮套，凸轮套设置于滑槽内部，凸轮套上的凸轮限位块能够进出限位槽，滑动轴上还连接有转动执行装置，传动装置通过转动执行装置带动滑动轴旋转，滑动轴上还连接有预紧件。本发明还提供一种具有该开门限位机构的门板总成和装甲车，与现有技术比较本发明的有益效果在于：该开门限位机构能够很好地对门板总成进行限位，操作人员可以便捷地实现对门板总成的限位、定位和释放。
