Description
Technical field
The present invention relates to bicycle rack field, particularly to a kind of network structure vehicle frame and making thereof
Method.
Background technology
The birth of carbon fiber structural cycle frame, although change revolutionaryly and reduce certainly
The weight of driving, also improves intensity, rigidity simultaneously, but for excelsior players,
Rigidity/weight ratio still cannot meet the demand of pursuer, also gives designer simultaneously and creates
The biggest performance space, common carbon fiber cycle frame structure is the mode using lamination, this structure
Not having advantage in weight/rigidity, namely rigidity/weight ratio is poor, and needing to promote rigidity must
Enough weight need to be had to support.
Once there is designer that critical piece makes the network structure of braiding, the rigidity of this structure/
Weight ratio is to be significantly improved, but owing to netted parts have a lot of space, when riding
Air-flow can be made to avoid smoothly, air-flow the most also can be made to circle round, thus considerably increase and ride
The resistance of row, so, though structural rigidity has, weight is the lightest, but windage increases,
So being also to improve the speed ridden.
Summary of the invention
For the problems referred to above, it is an object of the invention to provide and can effectively promote rigidity/weight
Windage, the network structure vehicle frame promoting torsional strength and making side thereof can be reduced again while Bi
Method.
For reaching above-mentioned purpose, technical scheme proposed by the invention is: a kind of network structure car
Frame, including frame body, it is characterised in that: described frame body cross section depends on from inside to outside
Secondary for auxiliary layer, carbon fiber mesh reinforcing rib structure, the outer auxiliary layer of carbon fiber, institute in carbon fiber
In the carbon fiber stated, the outer auxiliary layer of auxiliary layer, carbon fiber mesh reinforcing rib structure and carbon fiber is tight
Combine.
Preferably, the described reinforcement quantity in carbon fiber mesh reinforcing rib structure is 3-9
Bar.
Preferably, the intersection of the described cross network structure in carbon fiber mesh reinforcing rib structure
Angle is preferably 30-60 degree.
Present invention additionally comprises the manufacture method of above-mentioned network structure vehicle frame, it is characterised in that include
Following steps:
Step 1: first make the auxiliary fixture of grid reinforcing rib structure, twine on auxiliary fixture
Around the network structure intersected, obtain grid reinforcing rib structure；
Step 2: stick auxiliary layer in grid reinforcing rib structural outer surface, then passes through preliminary filling
Gas also sticks auxiliary layer at inner surface；
Step 3: finally formed body frame structure for automotive, and pass through mold cavity at high temperature under high pressure
Molding, obtains network structure vehicle frame.
Preferably, the described reinforcement quantity in carbon fiber mesh reinforcing rib structure is 3-9
Bar.
Preferably, the intersection of the described cross network structure in carbon fiber mesh reinforcing rib structure
Angle is preferably 30-60 degree.
Use technique scheme, network structure vehicle frame of the present invention, it is to avoid simple net
The surface of trellis reinforcing rib structure has too many space to cause air-flow to circle round, and then increases wind
Resistance；The stability of reinforcement can also be reinforced simultaneously, thus promoting rigidity/weight to bicyclist
Amount than while can maintain again the windage as designing, additionally interlacing with ordinary construction
Reinforcing rib structure can also promote torsional strength, promotes the handling of bicyclist.

Detailed description of the invention
Below in conjunction with the accompanying drawings and detailed description of the invention, the present invention will be further described.
As shown in Figure 1 and Figure 2, a kind of network structure vehicle frame, including frame body 1, vehicle frame
Body 1 includes the positions such as seat pipe 101, upper pipe 102, head tube 103, down tube 104, with existing
There are common carbon fibers structure frame (see Fig. 3) and common net trellis reinforcing rib structure car in technology
Frame (see Fig. 4) is compared, and the inventive point of the present invention is frame body 1 cross section from inside to outside
It is followed successively by auxiliary layer 11 in carbon fiber, carbon fiber mesh reinforcing rib structure 12, carbon fiber outer the most auxiliary
Help layer 13, auxiliary layer 11, carbon fiber mesh reinforcing rib structure 12 and carbon in described carbon fiber
The outer auxiliary layer 13 of fiber is closely linked.Meanwhile, described carbon fiber mesh reinforcement
Reinforcement quantity in structure 12 can be arranged according to the location requirement of actual product, is preferably
The intersecting angle of the cross network structure in 3-9 bar, and carbon fiber mesh reinforcing rib structure 12
The angle intersected can adjust according to the tubular demand of parts, preferably 30-60 degree.
Present invention additionally comprises the manufacture method of above-mentioned network structure vehicle frame, it is characterised in that include
Following steps:
Step 1: first make the auxiliary fixture of grid reinforcing rib structure, twine on auxiliary fixture
Around the network structure intersected, obtain grid reinforcing rib structure；Described carbon fiber mesh reinforcement
Reinforcement quantity in structure is 3-9 bar；Cross network in carbon fiber mesh reinforcing rib structure
The intersecting angle of structure is preferably 30-60 degree；
Step 2: stick auxiliary layer in grid reinforcing rib structural outer surface, then passes through preliminary filling
Gas also sticks auxiliary layer at inner surface；
Step 3: finally formed body frame structure for automotive, and pass through mold cavity at high temperature under high pressure
Molding, obtains network structure vehicle frame.
Concrete, assessed the rigidity of vehicle frame by following vehicle frame rigidity: by will voluntarily
The hook pawl fixed flat of vehicle carriage, with the central point of head tube as fulcrum, fixes one horizontal in head tube
Bar, applies 10kgf loading at cross bar, away from head tube center 40cm at the 100cm of head tube center
Place surveys deflection and assesses its rigidity (see Fig. 5), designs the reinforcement implemented according to the present invention
The quantity difference of muscle changes the rigidity of vehicle frame, and cycle frame rigidity computing formula is:
K=F*L/ α, α=△ x*360/2 π ι
In formula: k is vehicle frame rigidity (unit: N.m/ °)；
F is the power (unit: N) applied；
L is vehicle frame head pipe center to the distance (unit: m) of the point of application；
α is the angle (unit: °) of initial conditions after deformation；
△ x is the deflection (unit: mm) of measuring point；
△ ι is vehicle frame head pipe center to the distance (unit: mm) of measuring point.
The cycle frame rigidity obtained for different reinforcement quantity is as follows:
From the foregoing, it will be observed that network structure vehicle frame of the present invention, vehicle frame can be effectively improved overall
Rigidity, the surface simultaneously avoiding simple latticed reinforcing rib structure has too many space to cause
Air-flow circles round, and then increases windage；The stability of reinforcement can also be reinforced simultaneously, thus
Can maintain again while promoting rigidity/weight ratio to bicyclist as designing with ordinary construction
Windage, additionally the reinforcing rib structure of interlacing can also promote torsional strength, and lifting is ridden
Person's is handling.
Although specifically show and describe the present invention in conjunction with preferred embodiment, but art
Technical staff should be understood that the spirit in the present invention limited without departing from appended claims
With in scope, in the form and details the present invention is made a variety of changes, be the present invention's
Protection domain.
