Description

convertible stroller

technical field

The utility model relates to a convertible leisure stroller, in particular to a convertible leisure stroller which integrates a baby trolley, an electric cradle and a children's electric car. the

Background technique

With the rapid development of China's economy and the improvement of people's quality of life year by year, baby strollers and children's electric vehicles have become essential products for infants and young children. A stroller is a tool cart for babies under two years old. Children's electric cars are mainly motor-driven toy cars used by children over two years old. There are only single-function baby trolleys and children's electric cars on the market at present, and there is no children's car that integrates these two functions.

At present, there are more and more categories of baby carriages on the market, but few products can meet the needs of infants and young children, and there are more and more safety problems with existing products on the market. Many strollers do not conform to the physical characteristics of infants and young children, and as babies grow older, it is easy to cause physical defects in infants and young children. In addition, the design functions of many infant products are not clear, do not conform to the physiological characteristics of infants, and have not developed targeted products. Moreover, different car models need to be purchased in different periods of children, resulting in unnecessary waste of resources. In addition, we conducted a questionnaire survey on the purchase and use of baby carriages and children's electric vehicles, and now summarize the above surveys:

⑴Parents will buy strollers when their children are 0-2 years old.

⑵Most parents tend to buy entertaining and educational baby carriages.

(3) Most parents hope that after using the stroller, they can continue to use the stroller with other functions to make the best use of it.

(4) 81% of consumers need strollers when they are walking, and 80% are pushing them when shopping. the

⑸Consumers generally hope that the stroller has a good shockproof function.

⑹At present, the price of children's electric vehicles on the market is relatively high, and ordinary families will not buy children's electric vehicles.

⑺The car body is heavy and cumbersome to operate.

⑻Most children's electric vehicles do not have shock absorbers. If the road conditions are not good, the electric vehicles are easy to be damaged by shock.

According to the survey and analysis, the following conclusions are drawn: baby carriages and children's electric vehicles have great market potential, but the technology of children's electric vehicles is not yet mature. Consumers hope to buy a baby walker that is cost-effective and can be used for a long time.

At present, the price of baby trolleys on the market is between 200 and 3,000 yuan, the price of children's electric cars is between 400 and 2,000 yuan, and the price of electric cradles is between 500 and 1,500 yuan. Parents need to spend thousands or even tens of thousands of dollars during the baby's growth period. buy three products. If there is a product that can integrate trolleys, children's electric vehicles and electric cradles, it will effectively save resources and reduce costs, and will be favored by consumers. the
