Description

一种母婴自行车Mother and baby bicycle 技术领域Technical field
本发明涉及一种自行车，尤其涉及一种母婴自行车。The invention relates to a bicycle, in particular to a bicycle for mothers and babies.
背景技术Background technique
现如今，自行车或电动自行车作为一个代步工具已广泛运用于人们的日常生活中，是大多是群众所热爱的交通工具，出行方便，成本低。现有需要携带儿童出行时，在自行车或电动自行车上安装后座已为普遍意识。但若携带婴儿出行，通过自行车或电动自行车是不方便且不安全的。因此，也有在自行车或电动自行车前端安装婴儿座椅，以携带婴儿。但将婴儿座椅安装在车的前端，对骑行者来说，转动把手会非常吃力，这样就要求骑行者需要比较好的体力，适用范围窄。Nowadays, as a means of transportation, bicycles or electric bicycles have been widely used in people's daily life. Most of them are popular means of transportation, which are convenient and low-cost. It is now common sense to install a rear seat on a bicycle or electric bicycle when traveling with children. However, it is inconvenient and unsafe to travel with a baby by bicycle or electric bicycle. Therefore, there are also baby seats installed at the front of bicycles or electric bicycles to carry babies. However, to install the baby seat on the front end of the car, it is very difficult for the rider to turn the handle, which requires the rider to require relatively good physical strength, and the scope of application is narrow.
发明内容Summary of the invention
为了克服现有技术的不足，本发明的一个目的是提供一种母婴自行车，包括婴儿车组件、自行车组件，根据骑行者的体力情况及婴儿的喜好，婴儿车组件可选择性地安装于所述自行车组件的前端或后端。In order to overcome the shortcomings of the prior art, an object of the present invention is to provide a mother-infant bicycle, including a stroller component and a bicycle component. The stroller component can be selectively installed in the bicycle according to the rider’s physical condition and the baby’s preferences. Describe the front or rear end of the bicycle component.
