The invention discloses a self-locking type variable air inlet grille structure. The grille structure comprises a plurality of grille blades which are arranged up and down, the grille blades are connected with a self-locking mechanism which can drive the grille blades to turn over to any opening position and keep the grille blades at the opening position, and the self-locking mechanism comprises aworm and gear device connected with the grille blades and a driving device capable of driving the worm and gear device to act. The grid blades can be self-locked at the completely-opened position andthe completely-closed position through the worm and gear structure, the self-locking function of the grid blades can be achieved without the need that the motor is in a continuous working state, a stepping motor can be replaced by a common motor, the cost is low, and the reliability is high. Meanwhile, the grid blades can be driven to act through the worm and gear structure, state switching between complete opening and complete closing is achieved, extra energy consumption is not needed, and safety and reliability are achieved.
本发明公开了一种自锁式可变进气格栅结构,包括上下布置的多个格栅叶片,格栅叶片连接有可驱动其翻转至任意开度位置并保持在该位置的自锁机构,自锁机构包括与所述格栅叶片连接的涡轮蜗杆装置和可驱动涡轮蜗杆装置动作的驱动装置。通过涡轮蜗杆的结构可使格栅叶片在完全开启位置和完全关闭位置自锁,无需电机处于持续工作状态即可实现格栅叶片的自锁功能,可使用普通电机替代步进电机,成本低、可靠性高。同时可通过涡轮蜗杆的结构驱动格栅叶片动作,实现完全打开和完全关闭之间的状态切换,无需额外的能源消耗,安全可靠。
