An accommodation device includes a seat assembly, at least one flexible adjustment strap and an accommodating cavity having a bearing portion and a flexible circumferential surrounding portion. The accommodating cavity is rotatable between a lying state and a sitting state. When in the sitting state, a side of the circumferential surrounding portion reaching a topmost point is a first side portion, and a side opposite to the first side portion is a second side portion. The bearing portion has at least two foldable portions forming a first portion close to the first side portion and a second portion far from the first side portion. The adjusting strap is tensioned by the seat assembly and the first side portion when in the sitting state. The second portion is moved to form a seat portion during rotation to the sitting state, and the first portion is supported by the adjusting strap to form a backrest portion.

A car seat carrier can include a carrier body sized and shaped to receive a complementary sized and shaped car seat. Moreover, the car seat carrier can include at least one rear wheel assembly attached to the carrier body and the at least one rear wheel assembly can include a fixed wheel. The car seat carrier can also include at least one front wheel assembly attached to the carrier body and the at least one front wheel assembly includes a swiveled wheel. Further, the car seat carrier can include at least one handle extending from the carrier body.

A stroller is disclosed. The stroller includes a support frame supported by at least two wheels. The stroller also includes a seat carrier support selectively, removably coupled to the support frame. A swing motor is operatively coupled to the seat carrier support. A seat swing mechanism extends downwardly from the swing motor. The seat swing mechanism has a seat yoke configured to receive and retain an infant seat. The seat swing mechanism is configured to swing the infant seat forwards and backwards when the swing motor is activated.

The present disclosure relates to a smart stroller and a method of controlling the same. The smart stroller includes a sensor part for sensing various information regarding a space in which a baby is seated and information regarding the surrounding environment in which the smart stroller is traveling. The sensed information is transmitted to a controller so as to be calculated as information for controlling operation of the smart stroller or information for informing to a user. This may enable the smart stroller to travel in a stable manner. This may also allow the user to check the state of the baby in real time and take necessary action.

A child restraint includes an infant carrier having a carry handle. The infant carrier may be mounted on a stroller frame or on a vehicle seat or may be carried by a caregiver after separation from the stroller frame or vehicle seat.

A foldable car seat carriage includes a frame unit and an engagement unit. The frame unit includes two leg frames. Each of the leg frames includes two legs pivotable relative to each other, and a driving mechanism. The driving mechanism has opposite ends connected pivotally to the legs at first and second intersections. The engagement unit includes two bayonets. Each of the bayonets has a linking portion connected pivotally to the driving mechanism of a respective one of the leg frames. For each of the leg frames, change of a distance between the first and second intersections of the driving mechanism and the legs during pivot action of the legs converts a position of the engagement unit relative to the legs.

Disclosed is a child carrier seat arrangement comprising: a child seat configured to receive a child; a carrier base detachably attached to the child seat; a wheel arrangement coupled to the carrier base, wherein the wheel arrangement provides movement to the child carrier seat arrangement; a processor coupled to the carrier base, wherein the processor is configured to: receive a first input to make the child carrier seat arrangement work in a luggage mode, wherein, in the luggage mode, a user is configured to carry the child carrier seat arrangement as hand luggage; receive a second input to make the child carrier seat arrangement work in a manual mode, wherein, in the manual mode, a user is configured to navigate the child carrier seat arrangement; receive a third input to make the child carrier seat arrangement work in an automatic mode; and a sensor module coupled to the processor, wherein the sensor module is configured to provide instructions to the processor in the automatic mode for autonomous navigation of the child carrier seat arrangement.

A foldable cart frame has a folding mechanism, a connecting seat, two rear legs, and a handle unit. The folding mechanism has a base seat, at least one guiding rod connected to the base seat, a sliding seat slidably disposed on the at least one guiding rod, and a linkage assembly moveably connected to the sliding seat. The connecting seat is movably disposed on the folding mechanism. The two rear legs are disposed on the base seat. The handle unit is moveably inserted through the base seat, is fixedly connected to the sliding seat, and can drive the sliding seat and the connecting seat to move. The two rear legs are driven by the linkage assembly. The foldable cart frame can be folded and expanded conveniently and quickly. The connecting seat and its connecting components can form a stable supporting structure after expanding.

Upper and lower platforms are connected by at least one adjustable telescoping pillar. The lower platform has bottom surface with at least one, e.g., at least three wheels affixed thereto. At least one engagement structure is mounted on a top surface of the upper platform to engage an infant car seat. When an infant car seat is mounted on the upper platform, a child, secured in the infant car seat, can be propelled to or from a motor vehicle by pushing on the infant car seat with the wheels in contact with the ground.
