Abstract

The utility model provides a bicycle frame assembled in a modularized mode. The bicycle frame assembled in the modularized mode comprises a front bicycle frame, a rear bicycle frame, a middle bicycle frame of a threesome bicycle, a middle bicycle frame of a tandem bicycle and locating pins. The bicycle frame of a one-man bicycle, the bicycle frame of the tandem bicycle and the bicycle frame of the threesome bicycle can be rapidly and conveniently assembled as needed. Due to the fact that assembly is carried out in the modularized mode, universality and interchange performance are high; when the bicycle frame of the tandem bicycle or the bicycle frame of the threesome bicycle needs to be assembled, a middle bicycle frame can be purchased in addition, the bicycle frame can serve as the bicycle frame of the one-man bicycle without adding the middle bicycle frame, the bicycle frame can be extended flexibly, the application range of the bicycle frame is broadened, and the bicycle frame is economical and practical; the assembled bicycle frame is high in overall structure rigidity and reliable in structure.

Description

A kind of cycle frame of modularization assembling

Technical field

Technical field of bicycles, particularly a kind of cycle frame of modularization assembling under the utility model.

Background technology

At present, known bicycle is more and more diversified, in order to meet people's living needs, has occurred tandem bicycle, three-person bicycle.In recent years, there are many knowledgeable people to improve bicycle.As Chinese invention patent (application number 201110140457.9) discloses a kind of " Modular bicycle assembly and double, three-person bicycle ", this design can interconnective modular assembly by the design of major parts of bicycle is become, and then be conducive to assembly and connection and become the versions such as single, double and three people, be convenient to organize production and consumption person's assembling voluntarily or adjustment simultaneously.Although this invention is easy to assembly voluntarily; But also have weak point, the structure of the each module of one structural modification for existing bicycle is larger; Its two in the time being assembled into three-person bicycle need four modules (wherein having used two intermediate modules) make assembling three-person bicycle entirety the rigidity of structure reduce, entirety reliability also reduced simultaneously.

Summary of the invention

for above-mentioned middle existence ground problem, the utility model proposes solution, its technical scheme is: the cycle frame that a kind of modularization assembling is provided.The cycle frame of this modularization assembling is made up of middle vehicle frame, the middle vehicle frame of two person bicycles, the locating dowel pin of front vehicle frame, rear vehicle frame, three-person bicycle.Can be assembled into voluntarily as required single cycle frame, tandem bicycle vehicle frame and three-person bicycle vehicle frame.

While assembling single bicycle, only the exterior notch of rear vehicle frame need be inserted after the inner tank mouths of front vehicle frame, then be plugged locating dowel pin front vehicle frame and rear vehicle frame are fixed, thereby the vehicle frame that has completed single bicycle is assembled.

When assembling tandem bicycle, only the exterior notch of rear vehicle frame need be inserted to the inner tank mouths of the middle vehicle frame of two person bicycles, the exterior notch of the middle vehicle frame of two person bicycles is inserted after the inner tank mouths of front vehicle frame; Plug two locating dowel pins again the middle vehicle frame of rear vehicle frame and two person bicycles is fixed, middle vehicle frame and the front vehicle frame of two person bicycles are fixed, thereby have completed the vehicle frame assembling of tandem bicycle.

The inner tank mouths that only exterior notch of rear vehicle frame need be inserted to the middle vehicle frame of three-person bicycle when assembling three-person bicycle, the exterior notch of the middle vehicle frame of three-person bicycle is inserted after the inner tank mouths of front vehicle frame; Plug two locating dowel pins again the middle vehicle frame of rear vehicle frame and three-person bicycle is fixed, middle vehicle frame and the front vehicle frame of three-person bicycle are fixed, thereby have completed the vehicle frame assembling of three-person bicycle.

The middle vehicle frame of three-person bicycle has inner tank mouths parallel with the axis of exterior notch and inner tank mouths and exterior notch with the middle vehicle frame of two person bicycles.

the beneficial effects of the utility model are: can assemble quickly and easily or adjust the assembling that realizes single cycle frame, tandem bicycle vehicle frame and three-person bicycle vehicle frame; In the middle of only need inserting one while being assembled into tandem bicycle vehicle frame and three-person bicycle vehicle frame, vehicle frame can be realized, and makes the integral structure rigidity of car body large; Modularization assembling, general interchangeability is strong, vehicle frame in the middle of can buying in addition in the time that needs are assembled tandem bicycle vehicle frame and three-person bicycle vehicle frame, while not adding middle vehicle frame, can make single cycle frame uses, be that vehicle frame can be expanded flexibly, expanded the range of use also both economical practicality simultaneously of vehicle frame.
