Embodiment Construction

[0011] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0012] Such as figure 1 As shown, the present invention discloses a specific embodiment of a child safety seat based on a negative Poisson's ratio material. The child safety seat includes two shoulder straps and an unlocker fixing belt, and the fixing belt is installed on the seat. Two shoulder straps are installed on the backrest of the seat, and the two shoulder straps and the unlocker fixing belt are connected or separated by the unlocker, and a tightening regulator is installed on the unlocker fixing belt.

[0013] The two shoulder straps and the unlocker fixing strap are both made of negative Poisson's ratio material, and the unit cell structure of the negative Poisson's ratio material is a star shape. When the two shoulder straps and the unlocker fixing strap are under tension, The bandwidth becomes larger and the length of the belt becomes ...

Abstract

The invention discloses a child safety seat based on a negative poisson ratio material. The child safety seat comprises two shoulder straps and a unlocking device fixing strap. The two shoulder straps and the unlocking device fixing strap are all made from the negative poisson ratio material. The unit cell structure of the negative poisson ratio material is in a star shape. When the two shoulder straps and the unlocking device fixing strap are tensioned, the strap width is increased, and the strap length is decreased. The child safety seat is simple in structure and convenient to use; and comfort and safety are both considered, and the child safety seat is suitable for being used by a child.

Description

technical field [0001] The invention relates to the technical field of automobile restraint systems, in particular to a child safety seat based on negative Poisson's ratio materials. Background technique [0002] Child safety seats are more and more valued by the public. At present, the seat belts on most safety seats are mainly made of woven cloth. When a car collides, the seat belts are tightened to protect children. However, due to the use of The woven fabric material, in the process of being tightened, will exert great pressure on the torso of the child and cause injury to the child. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a child safety seat based on a negative Poisson's ratio material for the defects involved in the background technology. [0004] The present invention adopts the following technical solutions for solving the problems of the technologies described above: [0005] A child safety sea...
