Description

A foldable elderly moped

technical field

The utility model relates to a booster bike, in particular to a foldable old booster bike.

Background technique

With the aging of society in our country, there is a great market demand for mobility vehicles for the elderly to travel. First of all, they need power assistance instead of riding; secondly, considering the use and storage environment of the elderly in the city, they hope to be light and foldable. It can be easily folded, lifted, transported to the home through the elevator, and can be conveniently placed at home; these demands cannot be met by the current electric mopeds for the elderly on the market.

At present, the elderly mopeds on the market are basically composed of a fixed metal frame chassis, a fuselage, plus plastic shell decorations, seats, batteries, circuits, motors, etc.; they are large in size, heavy in weight, and cannot be folded. The car body structure requires a special space for storage and cannot be taken home.

As can be seen from the elderly mopeds currently on the market, their heavy weight and non-foldability are the biggest problems affecting the purchase and use of mopeds by the elderly in modern cities.

The heavy weight is due to the chassis structure designed for carrying decorative plastic parts, large batteries and other load-bearing forces other than the load-bearing capacity of the car body structure; it cannot be folded because the chassis frame of this type of car itself is heavy. As well as the integrated design of the plastic parts of the decorative shell, it is inconvenient to make a folding structure. Even if it is made into a folding structure, it is inconvenient to fold due to the weight and the influence of the decorative shell.
