Description

Special portable frame of car safety seat
Technical Field
The invention belongs to the technical field of automobile appliances, and particularly relates to a special portable frame for an automobile safety seat.
Background
At present, with the development of social economy, more and more families have automobiles, and it is also a common situation in people's lives that adults take children to drive. With the increasing importance of driving safety, the child car safety seat is also widely used by people. However, no matching product for the automobile safety seat exists in the market, so that the automobile safety seat can be only used on a rear seat in an automobile. To the infant, the children's handcart is the indispensable instrument of riding instead of walk when going on a journey, when the adult carries child to drive when going out, just need carry the children's handcart in addition, the children's handcart has also become the must luggage in the vapour car trunk, but the children's handcart appearance is wide big heavy, even if fold up also can occupy certain storage space, has increased the burden of luggage in the car to when at every turn needing to use, carry also very trouble.
Through the above analysis, the problems and defects of the prior art are as follows: child car safety seat can only use inside the car, and the instrument children handcart of riding instead of walk that infant's must possess can only use on the road surface, and when the adult carried infant and drives a car and go out, just need carry children's handcart in addition, has increased the burden of luggage in the car, and it is also very inconvenient to make a round trip to carry during the use.
The difficulty in solving the above problems and defects is: the structure of the child automobile safety seat on the current market is researched and analyzed, and the connection mode and the structure of the automobile safety seat and the automobile seat are known. The types and functions of the automobile safety seat are researched and analyzed, and a combination mode of the automobile safety seat and a matched frame is searched.
The structure to the children's handcart on the market carries out research and analysis, knows the folding mode and the structure of frame, designs folding back small, light in weight, uses convenient frame structure.
The combination mode of the frame and the automobile safety seat is designed, and the safety and the stability of the frame and the automobile safety seat are ensured.
The significance of solving the problems and the defects is as follows: the design is strong in universality, and the special frame can be matched with the automobile safety seat, so that the automobile safety seat for children can be installed on the frame, and the overall structure after the installation is finished can be used as a trolley for children to push on the road surface, so that the automobile safety seat for children becomes a walking tool for infants. The child automobile safety seat can be used in an automobile and can be pushed on the road surface, and the utilization rate of the child automobile safety seat is greatly improved. The baby stroller has the advantages that the baby stroller is replaced, the temporary walking tool becomes a baby, when an adult drives a car to go out, the baby stroller does not need to be carried in addition, when the baby stroller is pulled down to walk, the baby stroller safety seat in the car is directly taken down and mounted on the portable frame, the riding and walking requirements of the baby can be met, the mounting is convenient, and the safety and stability are high. The special frame for the child automobile safety seat can be folded and stored when not used, and is small in size and light in weight. The luggage storage and transportation space in the automobile is greatly saved, and the inconvenience caused by frequent transportation of the child trolley is also avoided.
