Foldable scooter

Abstract

The invention relates to the technical field of scooter equipment, in particular to a foldable scooter which comprises a chassis frame, a seat, a backrest, a folding support and a telescopic driving unit, the folding support comprises a first support and a second support which are rotationally connected and are parallelogram connecting rod mechanisms, and the two ends of the folding support are connected with the chassis frame and the seat respectively; the first support and the second support are in linkage connection through a first linkage piece, the backrest is hinged to the seat and is in linkage connection with the folding support through a second linkage piece, and when the telescopic driving unit drives the folding support to be unfolded or folded, lifting of the seat and unfolding or folding of the backrest can be driven in a linkage mode; according to the foldable scooter, in the folding process, the seat ascends and descends relative to the chassis frame, does not move forwards and backwards or only moves forwards and backwards in a small range, ascending and descending of the seat and unfolding and folding of the backrest can be synchronously linked, and the foldable scooter is simple and compact in structure, ingenious in design and convenient to use.

Description

technical field [0001] The invention relates to the technical field of scooter equipment, in particular to a foldable scooter. Background technique [0002] The scooter is a means of transportation that assists the movement of people, and is especially suitable for the elderly and the physically challenged. In order to facilitate storage and transportation, it is usually required to have a small volume during storage and transportation. At present, there are two main ways to reduce the size of the scooter. The first is to use a quick-release and quick-install structure. The advantage of this method is to reduce the weight and volume of a single component, but it is inconvenient to use, especially the body. It is even more inconvenient for the inconvenient to use; the second is the use of a folding structure, with manual folding and electric folding. The folding structure can not only reduce the volume of the scooter, but also is convenient to use, so it is very popular. How...

Problems solved by technology

At present, there are two main ways to reduce the size of the scooter. The first is to adopt a quick-release and quick-install structure. The advantage of this method is to reduce the weight and volume of individual parts, but it is inconvenient to use, especially the It is even more inconvenient for those who are inconvenient to use; the second is to adopt a folding structure, which has two ways of manual folding and electric folding. The folding structure can not only reduce the volume of the scooter, but also is easy to use, so it is very popular

However, the foldable scooter currently on the market has the following disadvantages in the folding structure: it adopts the forward or backward folding method. Moving forward or backward, it is easy to interfere with other components installed on the chassis frame, which increases the difficulty of chassis frame design, structural complexity or structural size; the lifting of the seat cannot be linked with the unfolding and folding of the backrest, and the backrest needs to be folded manually. Although some can achieve linkage, the structure is too complicated, the structure strength is not enough, and it is easy to damage
