The invention discloses an automatic cover opening and closing mechanism. The automatic cover opening and closing mechanism comprises a base assembly, a hinge plate, a cover plate, a driving rocker arm, a driven rocker arm, an actuator and a contact switch, wherein an inwards-concave groove structure is arranged on the base assembly, one end of the driving rocker arm and one end of the driven rocker arm are assembled on the base assembly through a rotating pair, the other end of the driving rocker arm and the other end of the driven rocker arm are assembled on the hinge plate through a rotating pair, the hinge plate, the driving rocker arm, the driven rocker arm and the base assembly form a parallel four-rod structure, a cover plate is fixed to the top of the hinge plate, the contact switch is arranged at the front end of the base assembly, the cover plate is provided with a convex rib used for triggering the contact switch, the actuator is triggered through the contact switch, and the actuator is used for driving the driving rocker arm to rotate around the rotating pair of the driving rocker arm and the base assembly, so that the cover plate covers the groove structure of the base assembly or is opened in parallel. According to the automatic cover opening and closing mechanism, by realizing translation type side-moving opening of the cover plate, the possibility that dust enters a cover opening is greatly reduced, and automation of opening and closing actions of the opening cover can be realized.
本发明公开了一种自动启闭盖机构,包括底座组件、铰链板、盖板、主动摇臂、从动摇臂、执行器和触点开关,底座组件上设有内凹的凹槽结构,主动摇臂和从动摇臂的一端通过转动副装配在底座组件上,另一端通过转动副装配在铰链板上,使得铰链板、主动摇臂、从动摇臂和底座组件构成平行四杆结构,所述盖板固定在铰链板顶部;所述触点开关设于底座组件前端,所述盖板上设有用于触发触点开关的凸筋,通过触点开关触发执行器,所述执行器用于驱动主动摇臂绕其与底座组件的转动副转动,从而使得盖板盖合在底座组件的凹槽结构上或者平行的打开。本发明通过实现盖板的平移式侧移开启,大大降低了灰尘进入盖口内的可能性,且能实现口盖开关动作的自动化。
