Structure Design And Simulation Analysis Of Multifunctional Child Safety Seat

With the popularity of the family cars in China, the probability of parents bring theirchildren with them to travel is higher. However, The safety and convenience of Children’spassenger still face a serious test. The safety of child passengers have not been correctunderstood and paid enough attention by many parents, In addition, regular car occupantrestraint system are developed for adults, it can’t provide enough effective protection to childpassengers, even for the children will add to the damage. For the past few years, In order toprovide more effective protection for children, Vehicle designer researched the Child RestraintSystem for children especially, Mainly on the car seat add addition of a device, In case ofcertain acceleration, through the limit children’s crew displacement and not harm to theirfragile physiological organization, Then to provide effective protection to children, Inadditional, When parents bring their children with them to travel, they still need to carry aheavy trolley car, This greatly reduced the convenience of travel. Therefore this paperdeveloped a multi-function child safety seats which can improve children’s safety andconvenience.The method of CAD was used for the design of child safety seat on the structure. MainlyIncluding ISOFIX, connector of trolley, Angle adjusting device and height adjustment device,Installation and unlock the device, Seat belts components, Foot pedals components and Fencecomponents and so on. This paper had accomplished the sample preproduction of the childsafety seat finally. The method of CAE was used for the study of child safety seat on thesimulation analysis. Established the multi-function child safety seats finite element model,demonstrated the credibility of the simulation analysis. This paper based on the" RestrainingDevices For Child Occupants of power-driven Vehicles "to the test design. IncludingComponent testing design and whole car crash test design, completed some preparation forthe last tests.Research Results Showed that a car seat and a trolley seat can all realize by themultifunctional child safety seat, and Convenient in to switch between them. This structurehas a wide adaptability and higher ride comfort. The structure of ISOFIX can improve theconvenience and reduce the installation mistake made by parents. In a collision, this structurestrength and stiffness get a qualified requirements. and the damage parameter of child allkeeps in regulations requirements. This safety seat can provide effective protection for the children aged approximately from0to3years old.
