A buffer mechanism of a child safety seat comprises a riding hub body, wherein a floating plate capable of moving up and down is arranged on a riding surface of the riding hub body, and an elastic structure for buffering and supporting the floating plate is arranged between a riding shell and the floating plate. The child safety seat buffer mechanism is simple in structure, long in service life and capable of buffering and damping.
Description
Technical Field
The present invention relates to child safety seats, and more particularly to a cushioning mechanism for a child safety seat.
Background
Child safety seats are auxiliary seats that are mounted on car seats for children to sit on and ensure safety of the child during driving. In the existing safety seat, in order to protect children from vibration during driving or damage during collision of the vehicle, a buffer and shock-absorbing structure is arranged on the automobile safety seat, as shown in TW588001B, when the automobile and the child seat in the automobile are impacted, the backrest angle is rotated through elasticity so as to slow down the impact of the shoulder strap on the backrest on the shoulders of the children, however, the riding area is a fixed plate, and the spine of the children cannot be slowed down. As shown in chinese patent CN200680049767.7, a soft plastic or cloth is mounted at the upper end of the seat base to form the whole seating surface, under which a space is provided in the seat, and when the car vibrates or is impacted, the seating surface sinks down and enters into the space, and the sinking of the seating surface is used as a buffer, however, after the service time is long, the soft seating surface is easy to generate elastic fatigue or harden, and is permanently sinking deformed, so that the buffer and shock absorbing effect is lost, even if a shock-absorbing pad is additionally arranged in the space, the cushion can only be used as a second layer buffer for impact, and the permanent deformation of the seating surface cannot be changed or slowed down, so that the buffer and shock absorbing skill is lost.
Disclosure of Invention
The invention aims to provide a buffering mechanism of a child safety seat, which has a simple structure and long service life and can buffer and absorb shock.
The invention relates to a buffer mechanism of a child safety seat, which comprises a riding hub body, wherein a floating plate capable of moving up and down is arranged on a riding surface of the riding hub body, and an elastic structure for buffering and supporting the floating plate is arranged between the riding hub body and the floating plate
According to the child safety seat buffer mechanism, the floating plate can move up and down, and the elastic structure provides buffer supporting force for the floating plate, so that the elastic structure and the floating plate support a child together; when the child uses the safety seat, the buttocks of the child are contacted with the floating plate on the riding surface, when the weight of the child is larger than the elasticity given to the floating plate by the elastic structure, the elastic structure can play a role in buffering and damping in the normal driving process and the process of applying external force to the vehicle (such as bumping caused by collision and uneven ground, and the like), and when the weight of the child is smaller than the elasticity given to the floating plate by the elastic structure, the elastic structure can play a role in buffering and damping only in the process of applying external force to the vehicle due to bumping caused by uneven ground or the collision on the vehicle during driving, and at the moment, if the resultant force of the external force and the weight of the child is larger than the elasticity of the elastic structure, the elastic structure can play a role in dispersing the external force so as to protect the safety of the child; therefore, the safety seat buffer mechanism for children can effectively ensure personal safety of children. The child safety seat buffer mechanism is simple in structure, the elastic structure is used for supporting the floating plate, the elastic structure is in butt joint with the floating plate to give the floating plate an upward supporting force, the elastic structure and the floating plate support the child together, and the service life of the child safety seat buffer mechanism is effectively prolonged.
