Description

Child safety seat Technical Field The present application relates to a child safety seat including an anti-misuse mechanism. Background Child safety seats are a common device that is secured in a vehicle, such as an automobile, to provide a safe riding environment for the child. In some cases, the child safety seat is arranged to be rotatable 360 degrees about the vertical axis, i.e. the seat is rotatable between a forward position (the seat facing the direction of travel of the vehicle) and a rearward position (the seat facing away from the direction of travel of the vehicle). To ensure safety, children typically under 15 months use child safety seats in the rearward position. To prevent a user from erroneously placing a child of 15 months or less in the child safety seat in the forward position, the child safety seat is provided with a misuse preventing mechanism of the rotational direction. In the child safety seat provided with the misuse prevention mechanism, the user can switch the child safety seat to the unlocking mode that allows rotation to the forward position or the locking mode that does not allow switching to the forward position by the operation member of the misuse prevention mechanism. However, the operating member of the existing misuse preventing mechanism does not have an automatic position pushing and positioning mechanism, and an operator may not operate the operating member in place, so that the seat mode is not actually switched, and misuse of the seat direction is finally caused, thereby bringing hidden danger to the trip safety of children. A turntable is typically provided between the seat and the base to allow the seat to rotate between a forward position and a rearward position. In some cases, it is desirable that the seat be separable from the turntable in order to replace the seat or move the seat into other use environments. Accordingly, there is a need to provide a child safety seat anti-misuse mechanism whose operating member is capable of automatic push positioning, and which allows separation of the seat from the turntable. Disclosure of Invention A child safety seat according to the present application includes a base, a dial positioned above the base to rotate about a substantially vertical axis between a forward position and a rearward position relative to the base, a seat positioned above the dial to rotate with the dial, the forward position being a position in which the dial faces the seat forward, the rearward position being a position in which the dial faces the seat rearward, and an anti-misuse mechanism disposed between the base, the dial and the seat and including an operating member mounted on the child safety seat to be movable relative to the seat between a first position and a second position such that the anti-misuse mechanism can prevent or permit relative rotation between the dial and the base, wherein the operating member automatically moves to the first position when the operating member approaches the first position toward the first position beyond an intermediate position between the first position and the second position, and the operating member automatically moves to the second position when the operating member approaches the second position beyond the intermediate position. In one embodiment, the anti-misuse mechanism further comprises a positioning piece arranged on the child safety seat and abutted against the operating piece for enabling the operating piece to automatically move to the first position or the second position when the operating piece approaches to the first position or approaches to the second position. In one embodiment, the operating member includes a ridge that protrudes toward and abuts the positioning member, causing the operating member to automatically move toward the first position or the second position. In one embodiment, the operating member comprises a sliding part capable of sliding relative to the child safety seat, two positioning concave parts arranged on the sliding part, the positioning member comprises a convex part, when the operating member is close to the middle position, the convex part is abutted against the ridge part, so that the operating member can automatically move to the first position or the second position, and when the operating member passes over the middle position and is close to the first position or the second position, the convex part is abutted against the corresponding positioning concave part and pushes the operating member to the first position or the second position. In one embodiment, the operating piece further comprises a poking part connected to the sliding part and capable of driving the sliding part to slide relative to the child safety seat. In one embodiment, each of the positioning recesses extends in an arc surface with respect to the sliding portion, and the convex portion has an arc profile adapted to the positioning recess. In one embodiment, the protrusion is movable rel
