The invention provides the automatic gear shifting child safety seat which is simple in structure, capable of automatically shifting gears forwards, backwards, rotates and is convenient and fast to operate.

The technical scheme adopted by the invention is as follows: the utility model provides an automatic gear shifting children's safety seat, includes base, seat body, its characterized in that: the seat is characterized in that a rotary stepping motor and a ball head support column are fixedly arranged on the base, the rotary stepping motor is connected with a rotary pinion, the rotary pinion is meshed with an inner gear ring of a rotary large gear disc taking the ball head support column as a central axis, the rotary large gear disc is connected below a rotary disc seat in a hanging manner through a connecting column, the ball head support column is in butt joint with and supports the center of the rotary disc seat, a fixed seat is fixedly arranged on the rotary disc seat, a feed stepping motor is arranged on the fixed seat and drives a feed gear, the feed gear is meshed with and supports a driving gear plate arranged in the rear lower part of the seat body, the seat body is arranged above the rotary disc seat, four guide grooves in the front-back direction at four rectangular corners are symmetrically arranged on the seat body by the central axis, more than four guide columns which are respectively and correspondingly penetrated into the four guide grooves are arranged on the rotary disc seat, and a groove cover plate corresponding to the radian of the guide grooves is tightly connected on every two guide columns on the same side of the central axis through bolts, the seat body is limited by the slot cover plate and the rotating disk seat from top to bottom respectively and can move back and forth in the limiting space.

The upper end face of the base is an inclined plane, and the rotary stepping motor is arranged at the high position of the inclined plane.

And a chassis cover is clamped on the rotary large gear disc and the rotary disc seat.

The guide post is of a guide wallboard post structure.

The automatic control rotary stepping motor is adopted, and the rotary pinion is meshed with the rotary pinion to drive the rotary pinion disc to rotate, so that the seat body is driven to rotate and shift gears through the guide wallboard columns, and the guide wallboard columns and the guide grooves restrict the seat body to rotate stably; the automatic control feeding stepping motor is combined for driving, the driving toothed plate is meshed and driven through the feeding gear, so that the seat body is driven to move back and forth through the driving toothed plate and shift gears along the rack structure on the driving toothed plate, the limiting guide grooves of the guide wall plate columns restrict the seat body to move back and forth and are limited between the groove cover plate and the rotating disk seat during back and forth movement, and the back and forth movement is stable. The whole structure is simple and compact, the operation is convenient and fast, and the automation degree is high.
