Abstract

This invention discloses a collapsible bicycle capable of being collapsed into a shopping cart structure. This invention is a collapsible bicycle capable of being pedally or electrically driven. The collapsible bicycle includes a front wheel set and a rear wheel set. The rear wheel set extends with a main bicycle frame from a rear wheel axis thereof. The main bicycle frame is engageable to or detachable from the front wheel set, and is pivotally connected to the front wheel set and the main bicycle wheel through a link. When the main bicycle frame is detached from the front wheel set, the main bicycle frame is rotatable upwards to drive the rear wheel set to approach and join the front wheel thereby forming a shopping cart structure. The link prevents the front and rear wheel sets from separation during the operation. When the main bicycle frame is laid even to clasp to the front wheel set, the front and rear wheel sets are expanded into a bicycle structure. The collapsible bicycle can be easily and expeditiously converted into an electrically driven bicycle structure so as to enhance its convenience in use.

Description

-^ 416819 V. Description of the invention '" —— [Technical Field] = The invention is about a folding bicycle that can be driven by electric means with folding to shopping, especially a bicycle that can be unfolded into a normal state, and When needed, it can be quickly formed into a convenient shopping cart. Ώ 俾 It also provides rest and shopping functions, which is suitable for family life. [Previous technology] Conventional folding bicycles are developed like conventional bicycles, which are large in size and difficult to survive. Folding a bicycle into a small volume has gradually become an important bicycle in the industry. So far, its progress has been noticed by reducing its weight or improving its performance. Although a folding bicycle cannot be ruled out due to the following obstacles: 1. Although conventional folding type has a weight of ten kilograms by itself, this weight inevitably forms a burden, not to mention that — the volume of the bicycle is still a certain scale, and it is on-machine. 2. For It is equipped by a remote worker, so it is customary to use a folding bicycle instead of using it. However, when the user wants it, it is not convenient to worry about the risk of losing the folding bicycle. Therefore, riding has a long history for many years. It has the disadvantage of being easy to lose, and the development direction of the structure for the convenience of user storage and portability. However, since the first foldability has been quite limited, most of the industry has combined the structure and failed to make important changes. The advantages of bicycles cannot be reached, but it is still not popular today. Even if you give it to a young man, is it still a housewife? Moreover, it is still inconvenient to do it on its own after the discount. The motorcycle is a practical transporter. It is used for community leisure or short-distance shopping, especially when you need to enter the house to take a car, and you must give up some shopping fun.

Page 4 3S19 V. Description of the Invention (2) From this, it can be seen that the bicycle industry in Hong Kong is unable to travel and feels that it is necessary to better the #users. Finally, the shopping cart structure has been successfully researched. It is said that the bicycle can be folded regularly into a field that can enjoy shopping, which is the former [invention purpose] The folding bicycle of the present invention allows the user to make shopping more convenient and keep the bicycle of the present invention. Conventional folding provides the user with a usable state to develop the folding bicycle structure of the present invention, so as to increase the usage of conventional folding researchers. The traditional folding mobile tools that have been overcome have completed the development of this folding bicycle. The present invention often takes advantage of its structure of riding a shopping cart, and there are still many development spaces for excellent bicycles that have not been brought before. The above-mentioned conventional folding problem 'is an urgent need to improve and innovate, and bicycles have made a major change to promote after many years of painstaking and meticulous research. * A electric drive can be folded into an innovation that has not been achieved just before. And when the user needs it, 'to facilitate the user to push forward, the folding bicycle is thrown into another brand-new invention. In order to provide a structure that can be folded into a shopping cart: the MEMS cart can be folded into shopping according to the needs of the user: worrying about the parking problem of the bicycle, and can enjoy the height of providing a folding bicycle that is easy to store and has the advantages of To make the most of it, the folding bicycle can be maintained at any time. It can be driven by electric means: ::: can be easily installed into an electric bicycle knot
