Hole.
Pass through above-mentioned technical proposal, the vehicle frame of bicycle is resolved into two parts of triangular portions and chain stay, passes through connection
Seat carries out assembly connection；Because the main function that triangular portions and chain stay rise in vehicle frame is different, triangular portions are mainly used in holding
By bicyclist body weight, it is necessary to there is higher intensity；And chain stay is mainly used in fixing trailing wheel, it is necessary to have preferably elasticity and shock-absorbing
Effect, the requirement to intensity are relatively low；Different materials is used in triangular portions and chain stay, can effectively utilize material
Characteristic strengthens the effect of triangular portions and chain stay, optimizes the overall performance of cycle frame.
Preferably, chain stay includes left chain stay and right chain stay, and left chain stay and right chain stay are relatively arranged on the both ends of the surface of connecting seat,
The connection end of a left side first of left chain stay is provided with the left connecting pole being engaged with the groove of connecting seat；The groove side wall of connecting seat is provided with
Spacing depression for spacing left connecting pole；The left through hole for installing pedal is additionally provided with left first connection end.
Pass through above-mentioned technical proposal, suitable for double-arm bicycle；Spacing depression is set in the groove side wall of connecting seat,
The position of chain stay is further limited, prevents chain stay from rotating motion.
Preferably, chain stay includes a chain stay, and located at a side end face of connecting seat, the groove side wall of connecting seat is provided with limit
Position depression, the first connection end of chain stay are provided with the connecting pole being engaged with the groove of connecting seat；Use is additionally provided with first connection end
In the through hole of installation pedal.
Pass through above-mentioned technical proposal, suitable for single arm type bicycle；Spacing depression is set in the groove side wall of connecting seat,
The position of chain stay is further limited, prevents chain stay from rotating motion.
Preferably, it is provided with connecting tube between standpipe and seat pipe.
Pass through above-mentioned technical proposal, connecting tube is set between column and seat pipe, strengthens column and the connection sat between pipe,
Avoid because bicyclist's overweight causes the triangular portions of vehicle frame to deform.
Preferably, upper tube is additionally provided between the standpipe of triangular portions and seat pipe, upper tube is inclination or horizontally disposed.
Pass through above-mentioned technical proposal, upper tube is set between the seat pipe and standpipe of triangular portions；When upper tube is horizontally disposed with, car
Sub- center of gravity is higher, and centre-of-gravity can more forward, and waist location is higher, and long-time comfortable riding is preferable, and suitable highway is ridden,
During high speed spot cars, rhythm is preferably controlled；And upper tube is obliquely installed, due to the Distance Shortened of each tie point of vehicle frame, same material car
Frame, rigidity are better than horizontal upper tube vehicle frame, and the vehicle frame of identical size is applied widely, and manufacturing cost can be greatly reduced；And by
It is in larger distance away from crotch in upper pipe distance, it is not easy to beat shelves, space is larger between two legs, is advantageous to the manipulation to vehicle body, fits
Close cross-country rough terrain and skill control.
Preferably, the side of chain stay is provided with reinforcement.
Pass through above-mentioned technical proposal, strengthen the intensity of chain stay, avoid chain stay because intensity is too low and flexural deformation.
Preferably, the mounting hole on connecting seat is 3, distribution triangular in shape.
Pass through above-mentioned technical proposal, using triangle rock-steady structure, mounting hole is reduced as far as possible, and can ensure to fix effect
Fruit.
Preferably, some eyelets are provided between the mounting hole and groove on connecting seat.
Pass through above-mentioned technical proposal, the material of connecting seat is saved, mitigate the important of vehicle frame.
Preferably, triangular portions are any one in carbon fiber, chrome-molybdenum steel, titanium alloy.
Pass through above-mentioned technical proposal, triangular portions are the parts for being mainly used to bear driver's weight on cycle frame, are needed
Intensity that will be higher；Carbon fiber has intensity height, non-corrosive, and the characteristics of easily repairing, and its strength conduction efficiency is high, shock absorption
It is good, but intolerant to scratching, the triangular portions of vehicle frame are sandwiched between the leg of jockey due to bicycle when in use, are not easy to be scratched, because
This is adapted to the triangular portions that vehicle frame is made of carbon fiber；Chrome-molybdenum steel processability is good, price material benefit, the vehicle frame impact absorbency of making
Can be good, but the strength of pedal can be also absorbed simultaneously；Contacted because the triangular portions of vehicle frame are not direct with pedal, so using chrome molybdenum
The triangular portions of steel making vehicle frame will not absorb the strength of pedal；The light specific gravity of titanium alloy, intensity is big, non-corrosive, is closed using titanium
Gold makes the triangular portions of vehicle frame, Portable durable.
Preferably, chain stay is magnesium alloy or titanium alloy.
Pass through above-mentioned technical proposal, it is mainly used to connect the part of trailing wheel, it is necessary to have higher on cycle frame during chain stay
Damping performance；Magnesium alloy strength is high, and damping performance is good, and density is low, contact, good biocompatibility；Due to chain stay directly with
Pedal is connected, more with human contact's chance, and vehicle frame chain stay is manufactured using magnesium alloy, can improve the damping performance of bicycle, lifting
Riding sense, moreover it is possible to mitigate car body weight, and feel with comfortable contact；The light specific gravity of titanium alloy, intensity is big, non-corrosive, true to nature
Effect is preferable, but manufacturing cost is high, and the chain stay of cycle frame is manufactured using titanium alloy, can improve the damping performance of bicycle；
Because the material usage of chain stay is relatively fewer, the cost of vehicle frame can be reduced to a certain extent.
