Description

Technical Field

[0001] The utility model relates to the technical field of child safety seats, and in particular to a gear position display structure and a child safety seat. Background Art

[0002] Child safety seats are a very important component of the car safety system. Child safety seats are designed to provide safety protection for children while the vehicle is driving. Child safety seats are usually installed on vehicle seats.

[0003] Among them, the child safety seat includes a base part and a seat part, the seat part is a seat or a carry basket, the base part includes a base shell and a rotating disk installed on the base shell, and the seat part is installed on the rotating disk. The seat part of the child safety seat can be rotated horizontally, so that the seat part of the child safety seat can be easily placed in or taken out of the child, especially in a narrow space inside the car, the seat part can be rotated to face the car door.

[0004] In the prior art, for example, CN210502385U, a rotating mechanism for a child safety seat includes a base, a turntable rotatably arranged on the base, and a locking unit for locking or unlocking the turntable; the side wall of the turntable has a plurality of positioning grooves along the circumference, and the plurality of positioning grooves include at least one working positioning groove and at least one pause positioning groove; the locking unit includes a moving part and an elastic reset part, the moving part is slidably arranged on the base, the moving part selectively engages with one of the positioning grooves of the turntable to lock the turntable, and the elastic reset part continuously applies a force to the moving part to make it enter the positioning groove. The operator can directly apply an external force to the above-mentioned moving part to overcome the force of the elastic reset part, or can apply an external force to the moving part through the turntable to overcome the force of the elastic reset part on the moving part.

[0005] According to the locking and unlocking scheme of the above-mentioned turntable, the user can lock or unlock the turntable through the locking unit, but there are still some shortcomings. The defect is that, first, the child safety seat does not have a gear position display. It is conceivable that if the elastic return member ages, the elastic return member will not be able to continuously apply the force to the movable member to make it enter the positioning groove, which will cause the sliding displacement distance of the movable member to be insufficient. Since the locking unit does not have a clear gear position display, it is foreseeable that after the movable member is reset, it is difficult for the user to judge whether the movable member has slid a sufficient distance to reset and engage the positioning groove; secondly, after the child safety seat is installed on the vehicle seat, due to the relatively small space inside the vehicle and insufficient light, the user usually stands outside the vehicle to adjust the direction of the seat part. The user's perspective is closer to the side of the child safety seat. However, the side of the child safety seat lacks a gear position display for locking or unlocking the turntable, which makes it difficult for the user to clearly understand the specific status of the locking unit from the side.
