Description
Technical field
The utility model belongs to cycle frame design field, is related to a kind of advanced composite material (ACM) pipe and the car of splice combinations
Frame structure.
Background technology
Bicycle is the short distance trip very easily vehicles, is also fashion, the fitness campaign mode of green, obtains
Consumers in general's likes.Vehicle frame is the core component of whole bicycle, also referred to as " soul " of bicycle, its weight, performance,
The cost determination class of bicycle.
The material that in the market is generally used for cycle frame has carbon steel, aluminium alloy, titanium alloy and polymer matrix composites
Four kinds.Carbon steel, the Al-alloy bicycle vehicle frame of routine are although cheap, but weight is larger；And the high price of titanium alloy is difficult to
Ordinary consumer is allowed to receive.Polymer matrix composites are because with designability is strong, material selects diversified, lightweight, specific strength
The outstanding advantages such as specific stiffness height, are widely used in the fields such as Aero-Space, track traffic, medicine equipment, sports equipment.Cause
This, the application case of composite unitized frame is also growing day by day.
But, it is poor, tight to there is expensive, complex manufacturing, batch stability in common composite unitized frame
The shortcomings of relying on experienced operator, production cycle length, inconvenient maintenance again, should as restriction composite unitized frame further genralrlization
Obstacle.
The content of the invention
Main purpose of the present utility model is to solve expensive existing composite frame, complex manufacturing, batch
Stability is poor, heavy dependence experienced operator, production cycle length, inconvenient maintenance the problems such as.
Technical solution of the present utility model is, including head tube, crossbeam pipe, seat pipe, four-way, seat stay pipe, it is right after fork hook,
Left back fork hook, chainstay, five logical and lower beam pipes, it is characterized in that, head tube, four-way, five it is logical, right after fork hook and left back fork hook two ends
Boss is designed with, boss is connected with each composite material tube with inserting mode, and boss root size and each tube end of institute's grafting
Outside dimension is identical, and the internal diameter size of pipe end is more than each boss outside dimension, and the section of tubular construction is uiform section or unequal section.
Boss indoor design has the hole with taper.
2 entrance holes are designed with head tube.
2 wire holes are designed with four-way.
Fork hook and left back fork hook bottom are designed with passage behind the right side.
The beneficial effects of the utility model are that the utility model is made up of composite material tube and joint, and both are combined into
It is unified overall.The use of the structure considerably reduces the weight and cost of vehicle frame, and can realize the batch metaplasia of vehicle frame rapidly
Production, with higher economic results in society and value.Structure of the present utility model considerably reduce cycle frame weight,
Save each part processing cost and greatly shorten fabrication cycle, mass production can be realized rapidly.
The characteristics of body frame structure for automotive has high-strength light, safeguards simple, easy to maintenance, solves in the market conventional metals car
Frame weight is big, it is perishable the problem of.
Meanwhile, for integral composite vehicle frame, its mould and product cost are greatly lowered, so as to be the car
The market competitiveness of frame is had laid a good foundation.

Embodiment
The possible implementation state of the utility model is only illustrated by embodiment below, and is not used to limitation the utility model institute
Category to be protected, makees this explanation.
The utility model provides a kind of advanced composite material (ACM) pipe and the vehicle frame of splice combinations.Including a head tube 1, a crossbeam
Fork hook 6 behind pipe 2, seat pipe 3, four-way 4, two seat stay pipes 5, a right sides, left back fork hook 7, two chainstays 8,
One five logical 9 and a lower beam pipe 10.
The two ends of fork hook 6 and left back fork hook 7 are designed with boss behind head tube 1, four-way 4, five logical 5, the right side, and boss is combined with each
Tubes of material is connected with inserting mode, and boss root size is identical with institute each tube end outside dimension of grafting, the internal diameter chi of pipe end
Very little to be more than each boss outside dimension, the section of tubular construction is uiform section or unequal section, and boss indoor design has the hole with taper
11, be designed with 2 entrance holes 12, four-way in head tube and be designed with 2 wire holes 13, it is right after fork hook and left back fork hook bottom be all provided with
In respect of passage 14.
Referring to view, the vehicle frame is divided into composite material tube and aluminum alloy joint two large divisions as can be seen from Figure；
Head tube 1 is connected with crossbeam pipe 2 and lower beam pipe 10 respectively, and the other end of crossbeam pipe 2 is connected with four-way 4, lower beam pipe 10
The other end be connected with five logical 9, it is and connected by seat pipe 3 between four-way 4 and five logical 9.Four-way 4 is connected with seat stay pipe 5 again, and five lead to
