Description

Foldable electric scooter and frame thereof

Technical Field

The invention relates to an electric vehicle, in particular to a foldable electric vehicle. The invention further relates to the technical field of folding products, in particular to a novel stay cord quick unlocking folding mechanism. The invention further relates to a bicycle saddle.

Background

An electric vehicle (or electric bicycle) generally refers to a motor vehicle that uses a storage battery as an auxiliary energy source and can realize a riding function. Electric vehicles may be used to ride and/or transport items. Electric vehicles have become common vehicles due to their characteristics of light weight, convenience and flexibility.

Most of the existing electric vehicles have large volume and weight, and are difficult to be brought into public transportation means such as buses and taxis, which limits the use of the electric vehicles to a great extent. In order to solve the defects of large volume and inconvenient carrying of the electric vehicle, researchers design the electric vehicle with a foldable structure. But the biggest difference between electric vehicles and bicycles is that they require an electric power unit to be installed to provide power. At the same time, the power unit in turn increases the overall weight and volume of the electric vehicle. The existing folding electric vehicle has at least one of the following defects: firstly, after the folding mechanism of the electric vehicle is difficult to fold at the same time, the volume is as small as possible; after deployment, the user is facilitated to ride and provide firm support. Existing electric vehicles either have a small volume after folding, but are inconvenient for the user to ride and/or difficult to provide a stable support structure after unfolding; or the folding bicycle is convenient for a user to ride and provide stable support after being unfolded, but still has larger volume and weight after being folded, and is not carried. Secondly, the structure is complicated, the folding step is complicated and inconvenient for users to use. Again, in order to achieve folding, the overall structural design of the electric vehicle is not secure enough. In particular, in order to realize folding of the whole structure of the electric vehicle, the whole structure is unreasonable and flexible operation and stable support cannot be provided in the running process of the electric vehicle. In addition, the existing folding electric vehicle has an irregular shape after being folded, and is easy to collide when being carried or placed. Finally, the electric vehicle cannot be towed (or pushed) after being folded, and can only be carried by the shoulder lever of a user. The chinese patent application No. CN201310302198.4 teaches a foldable electric vehicle wherein the foldable electric vehicle front frame, middle body, rear frame and two folding links. The folding electric vehicle taught by this patent can lift the main body upward by a lift handle, thereby bringing the front frame and the rear frame naturally closer to the main body and folding them together under the force of gravity. The foldable electric scooter disclosed in the patent application has a plurality of defects: first, the user must lift the middle body to fold by pulling the middle body, resulting in the user having to lift the middle body from bottom to top and overcome the weight of the entire middle body, even the entire electric vehicle, during the folding process of the foldable electric scooter, which makes the folding of the foldable electric scooter difficult. Secondly, the foldable electric scooter is complex in structure and still has a large volume and weight even after being folded. The foldable electric scooter is folded by pulling the middle body, so that the front frame and the rear frame are folded towards the middle body. Therefore, even if the foldable electric scooter is folded, it has a large volume and weight. Finally, the folding electric vehicle has too many pivots, which results in an insufficiently stable overall structure of the fold.

Accordingly, there is a need for an electric vehicle having a more stable folding structure.

The bicycle, body-building equipment and the like can relate to a folding mechanism, can fold products, is convenient to store, manage and transport, and particularly relates to a folding bicycle which is generally composed of a frame folding joint and a vertical pipe folding joint. The front wheel and the rear wheel are folded together through the folding of the frame, so that the length of the frame can be reduced by about 45 percent. After the whole car is folded, the whole car can be put into a boarding case and a folding bag, and a trunk of the car. The vehicle can be folded and unfolded manually without using external tools in the folding process. After folding, the seat rod is used as a supporting point so that the folded seat can stand stably. The folding bicycle is convenient and comfortable to carry and use, and the production process is mature. However, the existing folding locks for these products have complex structures, and the folding locks can be folded only by opening the safety lock and then opening the handle by hand, so that the operation is complex, and the whole product is heavy and inconvenient to operate and transport due to the fact that the folding locks are all made of metal and have heavy weight.

The bicycle saddle is an indispensable important component for providing sitting posture support, which is a decisive component for riding comfort, and is mounted on a bicycle seat tube.

The bicycle saddle on the market at present occupies a large space when being placed, is inconvenient to store, transport and carry, and adopts a bow structure.
