Description

Electric personal mobility attached to a stroller

The present invention relates to electric personal mobility attached to a stroller, and more particularly, by providing a technology for attaching to each other so as to provide the movement force of the stroller using personal mobility, which is an electric movement means used by one user, the user needs It is to provide electric personal mobility attached to a stroller that can be selectively used while being attached to and detached from the stroller according to the requirements of the present invention, acts as a brake when stopped, and improves the convenience of use by manipulating steering and driving with a simple operation of the user.

In general, a stroller is a relatively large one in which a thin wood, glass fiber, or metal body (box-shaped thing) is attached to the top of the car, and sometimes the upper body can be separated.

This stroller can be used from a newborn baby because it is mainly used for laying or sitting a baby. On the other hand, the baby car is a simple chair type car, and the seat part can be removed from the car body, and it is made to be folded. It is used in a sitting position, so it is preferable to use it from around 3 or 4 months of age. In addition, there are some that can be used as a three-wheeled vehicle after being used as a baby car, called a three-wheeled vehicle. Also, there is a face-to-face type in which the mother and the infant face each other as a form.

As the above-described stroller is manually operated and the user's power is used as power, the operating range and shape are determined according to the user's physical strength.

That is, when there are many uphill roads or when traveling a long distance, there is a problem in that a lot of physical strength is consumed and the use is reluctant.

In addition, although a manually operated brake device is installed in the stroller, if the operation is inexperienced or if it becomes loose after long-term use, the operating force of the brake decreases. There was a problem in that an accident occurred that was moved unexpectedly while unwinding.

Accordingly, recently, in accordance with the miniaturization and weight reduction of the electric driving means, a technology was developed and used to improve the convenience of use while increasing the safety as it is installed directly on the stroller to brake the wheels and to move by electric power.

However, even if the electric driving means is miniaturized and lightened, it becomes heavy as it adds to the weight of the stroller, and the volume increases, making it difficult to load in a vehicle, and there are problems in management such as continuously charging due to battery consumption.

In addition, there is a problem that the battery is installed in the stroller a child rides on, which may adversely affect the electromagnetic waves.

The present invention has been devised to solve the above-described problems, and an object of the present invention is to connect a stroller with a personal mobility used by one user, so that they can be used independently of each other and can be used independently of the type of stroller It provides electric personal mobility attached to a stroller that increases stability by performing the role of a brake in the mounted state, easy to operate as the user moves by button operation while riding, and improved convenience in use. .
