Description
Technical field
The utility model belongs to cycle frame, relates in particular to a kind of Electrical Bicycle vehicle frame that has the storage battery carriage.
Background technology
Electrical Bicycle is laborsaving than cycling, fireballing advantage and more and more be subjected to people's favor.At present Electrical Bicycle is laid the vehicle frame of storage battery, normally in vehicle frame Vee formation structure with about upright fork front end curve approximate right angle respectively after directly with the standpipe welding, and constitute the space of placement storage battery with chain stay.And the upright fork of this structure can produce distortion after pipe bent position is stressed, easily snaps with standpipe butt welding place; In addition, place the storage battery carriage of seat tube lower end center tap and chain stay weld to form by three metal sheets, make the storage battery carriage and must pass through three iron plates of stamping-out (lower reinforcing plate, end bracket and side guard plate), again respectively with multiple working procedures such as standpipe and chain stay welding, the expense of promptly taking a lot of work is expected, has increased the manufacturing cost of vehicle frame.Therefore, the people in the industry is for guaranteeing bicycle structure firmly and riding safety, and reduces production process, reduces manufacturing cost as far as possible, demands developing the novel vehicle frame that solves its technical matters urgently.
The utility model content
The purpose of this utility model aims to provide a kind of Electrical Bicycle vehicle frame that has the storage battery carriage, has both solved the firm bonded assembly technical barrier of above-mentioned upright fork and standpipe, has strengthened the structure of vehicle frame again; Both reduce multiple working procedures such as stamping-out blanking, welding, guaranteed moulded attractive in appearance of bicycle again.
Be to realize that the purpose of this utility model, the technical scheme of employing are, a kind of Electrical Bicycle vehicle frame that has the storage battery carriage mainly contains the standpipe of vehicle frame, upright fork, center tap, chain stay and forms vehicle frame Vee formation structure, and it is characterized in that: aspect is
The standpipe shoulder grafting head of type band both shoulders, its middle circular hole and seat tube upper end are affixed, and standpipe shoulder grafting head both sides both shoulders vestibule stands fork coupling grafting back solid welding respectively with about vehicle frame, and the longitudinal cross-section shape is
Storage battery lock box connecting panel, its upper end two sides and chain stay solid welding of the vehicle frame left and right sides, its lower end be provided with the storage battery slideway on the elongated hole that is spirally connected, shape of cross section is
The band double-vane the solid welding of storage battery box carriage between the chain stay of the left and right sides, the one end again with the solid welding of standpipe lower end, its other end is provided with the hangers that has elongated hole that is spirally connected with storage battery slideway lower end; The double-vane of described storage battery box carriage is provided with the knock hole with storage battery box pin joint, and the double-vane plane of its storage battery box carriage is vertical with standpipe.
Above-mentioned storage battery lock box connecting panel upper end is provided with bale handle.
Remarkable result of the present utility model is to adopt stamping forming standpipe shoulder grafting head, storage battery lock box connecting panel and storage battery box carriage and standpipe, upright fork and the common Electrical Bicycle vehicle frame of forming that has the storage battery carriage of chain stay to be skillfully constructed rationally, simple, save cost, safe and reliable, and the industry that is easy to is promoted; Also make product more durable because of product configurations is simple and direct, more affine audient, in a word, it can be rated as have novelty, creativeness, practical good technology.
