The invention provides a sitting and lying dual-purpose bracket switching mechanism of a bearing device, a seat and the bearing device, which comprises a bearing bracket and a rotating seat which are rotatably arranged on fixed seats on two sides of the bearing device, so that the bearing bracket can pivot and swing between a seat position and a sleeping box position; a conversion assembly is arranged on the rotating seat to drive the lever to drive the locking piece to be far away from the fixed seat, so that the bearing bracket is unlocked and can pivotally swing; or the driving lever is used for driving the locking piece to approach relative to the fixed seat, so that the bearing support is locked after pivoting and swinging. Therefore, in the conversion process of the bearing support between the seat mode and the sleep box mode, through the simple structure that the driving lever is connected with the locking piece, the locking piece can be driven to control unlocking or locking of the pivot swing of the bearing support, and the effects of being simple in structure and labor-saving in operation are achieved.
本发明提供一种承载装置的坐卧两用支架转换机构、座椅及承载装置,包括承载支架以旋转座可转动地设于承载装置两侧的固定座,使承载支架可于座椅位置及睡箱位置间枢摆,且在旋转座有转换组件而以驱动杠杆驱动锁定件相对固定座远离,使承载支架被解锁而可枢摆;或以驱动杠杆驱动锁定件相对固定座靠近,而使承载支撑在枢摆后被锁定。藉此,承载支架在座椅模式和睡箱模式的转换过程中,通过驱动杠杆连接锁定件的简单结构,即可驱动锁定件对承载支撑的枢摆进行解锁或锁定的控制,达到结构简单且操作省力的功效。
