The invention discloses a child automobile safety seat base. The child automobile safety seat base structurally comprises a lower cover, supporting legs and the like, a guide rail assembly which reciprocates along the front and back of the lower cover is additionally arranged on the lower cover, and the back ends of the supporting legs are hinged to the front end of the guide rail assembly, and after the front ends of the supporting legs suspend, the supporting legs can be folded relative to the lower cover or unfolded relative to the lower cover to support the ground; the lower cover is further provided with a limiting rod which is movably installed in a lifting mode, and backward movement limiting of the guide rail assembly is relieved or locked through lifting movement of the limiting rod; and the improved structure makes the supporting legs synchronously move forwards and backwards along with the guide rail assembly and are limited, so the base can meet the length dimension requirement of the industry standard no matter in a storage state or a use state, and the use safety is guaranteed. In addition, backward movement limiting of the guide rail assembly is achieved by mainly depending on the fact that the front ends of the supporting legs are folded and drawn close to the bottom face of the lower cover to synchronously push the limiting rod to ascend or by means of descending of the gravity effect of the limiting rod, and operation and use are flexible and convenient.

    本发明公开了一种儿童汽车安全座椅底座,其结构包括下盖、支撑腿等,主要是在下盖上增设有沿下盖前、后作往复移动的导轨组件,再将支撑腿后端铰接在导轨组件前端,则支撑腿前端悬空后,同样能够相对下盖折叠并拢或相对下盖展开撑地;同时,下盖上还设有升降活动安装的限位杆,并经该限位杆的升降活动而解除或锁定导轨组件的向后移动限位;因此,改进后的结构使得支撑腿也能随同导轨组件作同步前、后移动并限位,故底座不管处于收纳状态或使用状态时,都能符合行业标准的长度尺寸要求,从而保证使用安全性。另外,解除或锁定导轨组件的向后移动限位主要依靠支撑腿前端折叠并拢在下盖底面而同步顶推限位杆上升或利用限位杆本身重力作用的下降而实现的,操作使用更加灵活、方便。
