The invention discloses an electric side protection device of a child safety seat. The electric side protection device comprises a base, a side protection cover plate, a motor and a rack. The inner side of the side protection cover plate is provided with two sets of parallel slope-shaped sliding grooves which are opposite in ramp direction, the number of the racks is two, the racks are arranged on the base in parallel, the racks are provided with rack connecting columns matched with the adjacent slope-shaped sliding grooves, the motor drives the two racks to move in the opposite directions, and the rack connecting columns are connected with the rack connecting columns. And the rack connecting column is driven to reciprocate between the slope top and the slope bottom of the slope-shaped sliding groove, so that the side protection cover plate is driven to pop up or retract relative to the base. A user can control the device through voice or a mobile phone, using is very convenient, specifically, the motor gear is driven by the motor, then the rack is driven to rotate, the side face protection device is made to pop out automatically, gear teeth of the gear are meshed to move, and the device has the advantages of being stable in transmission, accurate in transmission ratio and the like.
本发明公开了一种儿童安全座椅的电动侧防护装置,包括底座、侧保护盖板、电机和齿条;所述侧保护盖板内侧设有2组平行但坡道方向相反的坡状滑槽,所述齿条为2个,平行设置在底座上,所述齿条上均设有与相邻的坡状滑槽相适配的齿条连接柱,所述电机驱动2个齿条向相反方向运动,带动齿条连接柱在坡状滑槽的坡顶和坡底之间往复运动,从而带动侧保护盖板相对于底座弹出或者缩回。使用者通过语音或者手机就可以操控,使用起来非常方便,具体为通过电机驱动电机齿轮,进而带动齿条转动,使侧面防护装置自动弹出,利用齿轮的轮齿相互啮合运动,具有传动平稳,传动比精确等特点。
