An infant swing rocking chair includes a frame, two rocking bars and a chair assembly. The two front legs are arc posts protruding forward; the front legs and rear legs are hinged through the leg joint, and the front legs and the rear legs have two working positions of unfolding & supporting and folding; the rocking bar has the working position of rocking and the working position of locating; the bottom of each rocking bar is hinged with the chair assembly through the chair joint to make the chair assembly have the working position for the swing and the working position for the rocking chair; and the infant swing rocking chair has two use modes: a swing and a rocking chair.

A portable activity center for use by a young child comprising a frame supported at a predetermined height above the ground by a plurality of rotatable or foldable legs. A tray is coupled to the frame and includes an opening and a seat support surrounding the opening and a seat is positioned within the opening and is securely attached to the seat support. A resilient suspension system operates to permit the seat and seat support to move in vertical reciprocating movement to allow the child to bounce. A cover interchangeable with the seat and positioned within the opening operates to convert the activity center into a table structure.

A swing seat includes a frame assembly and a seat assembly. The frame assembly includes a frame unit, and a rotating unit that is connected to a top end of the frame unit and that is rotatable relative to the frame unit about a swing axis which extends in an axial direction. The seat assembly includes a seat member, and a hanger arm. The hanger arm has a hanger portion coupled removably and co-movably to the rotating unit of the frame assembly, and a connecting portion interconnecting the hanger portion and the seat member, such that the seat member is swingable relative to the frame unit of the frame assembly about the swing axis.

The child car seat simulates the motions and sounds of a car seat being driven over a road in order to comfort and soothe an infant and to induce the infant to sleep. An infant may be placed on padding attached to the top interior of the seat body and restrained by a left blanket half and a right blanket half. A motion mechanism located in the base of the seat body may cause movement of the child care seat that resembles the movement that a car seat would experience in a moving vehicle. One or more speakers located within the shell of the seat body may play an audio program to simulate vehicular and traffic noises. The intensity and type of movement and the volume and specific audio program may be selected from controls located on the upper rear of the seat body.

A move and discover chair helps teachers transition to new education paradigm where children move and discover education with the teacher positioned in the midst of the children to encourage them in the excitement of learning. The chair stimulates the ability to focus on learning and to be more effective in one's work by allowing some level of movement, balance, fidgeting, and engagement with the background environment. The chair includes a concave end cap with a first side edge and an external concave surface, a convex end cap with a second side edge and an external convex surface, and a center section fixedly positioned between the concave end cap and the convex end cap and with an outer surface that is substantially straight in a directions between the concave end cap and the convex end cap.

The present invention relates to a device for taking care of infants, and a driving mechanism. The driving mechanism comprises a support, a first motion assembly and a second motion assembly, wherein a seat is arranged on the support, and since the first motion assembly and the second motion assembly are both arranged on the support, the first motion assembly drives the seat to swing in a first direction relative to the support, and the second motion assembly drives the seat to swing in a second direction relative to the support. Since the first direction intersects with the second direction, the motion of the seat is the superposition of the swinging in the first direction and the swinging in the second direction.

This invention provides a rocking chair comprising a rear support frame arranged with a rotating part, a front rocking frame pivoted to the rear support frame and used as a front support frame, and an electric rocking drive mechanism driving the front rocking frame to continuously rock back and forth relative to the rear support frame; when the front rocking frame continuously rocks back and forth relative to the rear support frame, the distance between the moving part and the rotating part is alternatively decreased and increased to lift and lower pivoting point of the rear support frame and the front rocking frame relative to support surface. The rocking chair has automatic rocking and lifting function, and no additional fixing frame is necessary. The power requirement is low. When the moving part and the rotating part are wheels, the rocking chair can also be used as a stroller.

Disclosed is a swinging drive control apparatus, including a controller and a motor, where the controller detects a counter-electromotive force of the motor and drives the motor according to the detection result. Also disclosed is a corresponding method, including: measuring a counter-electromotive force of a motor in a previous cycle; and comparing a maximum counter-electromotive force value with a preset value, and calculating a PWM pulse duty factor in a next cycle. By directly detecting the counter-electromotive force of the motor without using a sensor, the present invention implements swinging frequency and phase tracking as well as swinging amplitude control, and simplifies a control system.
