Description
Technical field
The utility model, about the bicycle frame structure of a kind of capable of regulating vehicle frame length and angle, refers to especially a kind of rider's of cooperation height and drives pattern stepless and adjust the bicycle frame structure such as horizontal throw, Yu Zuoguan angle of inclination, front fork stem angle of inclination etc. between forward and backward two axles distance, seat pipe and head tube.
Background technology
The body frame structure for automotive of bicycle mainly includes: a Five-way tube for socket stretcher; One is connected in this Five-way tube upwardly extending seat pipe; The one rear fork group that is connected to this pipe and this Five-way tube and extends back; One head tube; One is articulated in this head tube and to the front fork stem of downward-extension; And upper pipe and a lower pipe that connects this pipe and this head tube.Other accessory of bicycle includes: one is articulated in the trailing wheel in rear fork group; One is articulated in the front-wheel on front fork stem; One is connected in this pipe upwardly extending vertical tube of cushion and cushion; One is articulated in this head tube and upwardly extending stem and handlebar, has continuous action relation, and can control the direction that drives of this front-wheel between this stem and this front fork stem; One can be driven by this stretcher and the chain sprocket drive group to trailing wheel (or front-wheel) by transmission of power; An and brake gear etc.
Bicycle is for coordinating rider's (such as perambulator, teenager's car, cart etc.) of different heights and the different patterns that drives (such as the car of competing for speed, city car, cross-country car etc.), and all there is different set models at distance between each frame tube of its body frame structure for automotive and angle of inclination etc., such as horizontal throw, seat pipe angle of inclination and front fork stem angle of inclination etc. between forward and backward two axles distance, seat pipe and head tube, need to coordinate different car types, do different settings.Below give a few examples and be illustrated:
The difference of perambulator, teenager's car, bull wheel footpath car is except wheel footpath varies in size, and on it, the setting of pipe distance and forward and backward two axles distance also has difference.Generally speaking, the upper pipe distance of perambulator, teenager's car and forward and backward two axles are apart from all shorter, and the upper pipe distance of bull wheel footpath car and forward and backward two axles, apart from longer, drive to adapt to the personage that height is higher.
The larger car type in seat pipe angle of inclination and front fork stem angle of inclination (as the car of competing for speed, cross-country car), the pattern that applicable suburb drives at a high speed, now need larger seat tube angulation (the saddle tube angle initialization of for example competing for speed is 73-75 degree), to facilitate rider's the application of force of trampling.And larger front fork stem forward leaning angle (the car front fork stem forward leaning angle of for example competing for speed is set as 73-75 degree), sensitiveer handling to obtain.Meanwhile, in order to drive and to be beneficial at a high speed, trample the application of force, need to have long seat pipe to handlebar distance, the posture that rider is bent, reduces windage on the one hand, is beneficial to firmly and tramples on the one hand.Yet, while driving, to bend, be only applicable to more professional personage, common people can think that easy fatigue is more uncomfortable.Therefore be not suitable for the mode that drives of urban district low speed leisure type.
The less car type (as city car) in seat pipe angle of inclination and front fork stem angle of inclination is applicable to the pattern that drives of city, metropolitan area car low speed.City car to drive to lie fallow be main, speed is unhappy, stresses comfortablely, therefore the distance between seat pipe and handlebar is shorter, and rider can be driven by straight and upright upper body, for common people compared with indefatigability.Its front fork stem forward leaning angle and a seat tube angulation are set as 69-71 degree conventionally, and this less front fork stem forward leaning angle and seat tube angulation, be unfavorable for trampling and exert oneself, but the vibrations of the ground resilience that is dispersed, so traveling comfort is better.Yet this less seat is managed angle of inclination and front fork stem angle of inclination, and is unfavorable for high speed traveling, is also unfavorable for climbing.
Horizontal throw between seat pipe and head tube (being designated hereinafter simply as pipe distance), should have along with the height of different people difference, the people that height is higher, and hand and foot are all longer, the upper pipe distance that therefore need to grow.In addition, upper pipe distance, seat pipe angle of inclination and front fork stem angle of inclination, should be also slightly different along with the different patterns that drives, while driving pattern at a high speed, need to there be long forward and backward two axles distance or upper pipe distance, make rider can bend to make a spurt, and reduce windage; Simultaneously larger seat pipe angle of inclination, makes rider's pin step on the application of force more efficient.When urban district low speed drives, needing has shorter upper pipe distance, makes rider's comfortable driving of being come out boldly, and simultaneously less seat pipe angle of inclination and front fork stem angle of inclination, lowered the vibrations from ground.
The different handlebars that drive posture (dive and straight and upright) and arrange in pairs or groups (as curved in sport car and directly), its upper pipe needing is apart from also having difference.
Generally speaking, handlebar has: the flat handle that Mountaineering vehicle is used, the curved handle that sport car is used, the curved handle that gentlewoman is automobile-used.Though any handle, the rear bending angle of also having nothing in common with each other.Therefore; Select different handlebars, inevitable also can have influence on the horizontal throw of pipe, due to general vehicle frame welding fabrication, it on, pipe horizontal throw is fixed, therefore; When rider thinks arbitrarily to replace different handlebars, can make the horizontal throw of pipe become oversize or too short, the sensation that causes rider to have to have some setbacks.For example: flat change into sport car curved time, the horizontal throw of upper pipe becomes oversize, rider's lower driving of will lying prone to obtain, and allow and drive center of gravity and excessively move forward easily caused front overturning; Otherwise, sport car curved change into flat time, it is too short that the horizontal throw of upper pipe becomes, rider cannot drive with the posture of bending, and reduces windage, tramples therefore reduction of efficiency, also cannot drive at a high speed.
By above-mentioned several examples, the distance between each frame tube of known bicycle frame structure and angle of inclination etc., all need according to the rider of different heights and different drive pattern and do different settings.Yet the body frame structure for automotive of existing bicycle, after welding completes, its vehicle frame size is fixing, customer cannot change, no matter size is closed improper, the existing vehicle frame size of can only condescending to take this post, or select shorter or longer car tube head (device that connects handlebar and standpipe of front fork top), yet, the replacement length size of this car tube head is limited, especially the higher people of height, if in order to increase upper pipe lengthening distance car tube head, by the center of gravity that makes to drive, more reach, when descending or emergency brake, very easily, overturn, the safety of impact driving.Therefore, an inappropriate cycle frame drives for a long time, often causes athletic injury, has a pain in the back, and suffers untold misery, thereby loses the confidence to driving bicycle.The body frame structure for automotive of certain existing bicycle, also cannot coordinate different driving environment and drive pattern, and the habitual bicycle frame structure of this fixed measure is carried out to resetting of vehicle frame distance and angle of inclination.
China No. ZL02116476.2, ZL03264805.7 Patent Case, a kind of Collapsible bicycle is provided respectively, its technical characteristics is the upper pipe of bicycle to be made to the structure of length of tube in scalable adjustment, its main utility model object is can shorten the entire length of bicycle when not driving, the space taking while collecting to reduce.Certain above-mentioned Collapsible bicycle on adjusting during length of tube, also can relatively adjust forward and backward two axles apart from and seat pipe and head tube between horizontal throw, to be applicable to the personage of different heights, drive.But this telescopic pipe is when shrinking, in order to avoid trailing wheel, its telescopic pipe can only be done the design of level, therefore on adjusting during length of tube, front fork stem forward leaning angle and a seat pipe angle of inclination roughly keep identical, cannot fitted shaft apart from change and with its angle of inclination of adjustment; To such an extent as to when wheelbase shortens, easily front overturning while having lower abrupt slope, and the problem of less stable.
The structure that separately has a kind of habitual Collapsible bicycle, mainly that standard bicycle Central Plains is welded in to the upper pipe between head tube and seat pipe, block on the two sectional type of the slippage of can mutually stretching and manage, and be welded on vehicle frame in the mode of level, recycle a fasten bolt and give packing location.When its shortcoming is that in two sectional type level, pipe is flexible, can only adjust wheel base, cannot change the angle of seat pipe and front fork tube, still can not meet the different patterns that drives; And only use a fasten bolt to lock, form single-point locking condition, not only cause body frame structure for automotive built on the sand, and this locking point becomes a fulcrum, the radial component producing while driving, causes the phenomenon that on two sectional type, pipe deflects, and produces a relative torsion motion on two sectional type between pipe, while causing knight to drive bicycle, cannot effectively maintain balance, and then the derivative even unexpected problem of falling car of difficulty that drives.
The structure of above two kinds of habitual Collapsible bicycles, is all located at adjustable telescopic pipe the upper pipe of horizontal, causes the height of vehicle frame and upper pipe higher, is therefore unfavorable for that Ms gets on or off the bus.

The specific embodiment
Refer to Fig. 1 and Fig. 2, the bicycle frame structure of capable of regulating vehicle frame length provided by the utility model and angle, mainly includes: a Five-way tube 80 for socket one stretcher (scheming not shown); One is connected in this Five-way tube 80 upwardly extending seat pipe 81; The one rear fork group 82 that is connected to this pipe 81 and this Five-way tube 80 and extends back; One non-level telescopic tube assembly 13, by can relatively stretching, one first pipe fitting 10 and one second pipe fitting 20 of adjusting formed, and optionally change this first pipe fitting and the second pipe fitting relative distance, and then change the relative angle between each frame tube of bicycle, wherein this second pipe fitting 20 is connected in this pipe 81 and extends upward forward; At least one registration device 29, for this first pipe fitting 10 and this second pipe fitting 20 are locked on the fixed position after this flexible adjustment; One is connected in this first pipe fitting 10 and forward to the head tube 83 of downward-extension; And one be articulated in this head tube 83 and to the front fork stem 84 of downward-extension.The quantity of this at least one registration device 29 can be two, is arranged at respectively two place's diverse locations on the second pipe fitting 20.
The utility model more includes first support tube 102 that is connected in 13 of this pipe 81 and telescopic tube assemblies, makes this rear fork group 82, the first support tube 102 and telescopic tube assembly 13 jointly be configured to the good arch bar truck of a structural strength.The first simultaneously lower support tube 102 positions, except reducing the height of vehicle frame and cushion, the height of going up pipe simultaneously also can be lower, and being beneficial to Ms or child can get on or off the bus very easily.
This telescopic tube assembly 13 also can select to be connected in this pipe 81 near these Five-way tube 80 places, and it is the expected equivalent embodiment of the utility model.
This bicycle more includes: one is articulated in the trailing wheel 85 in rear fork group 82; One is articulated in the front-wheel 86 on front fork stem 84; One is connected in this pipe 81 upwardly extending vertical tube of cushion 87 and cushion 88; One is articulated in this head tube 83 and upwardly extending stem 89 and handlebar 90, and 84 of this stem 89 and front fork stems have continuous action relation, and can control the direction that drives of this front-wheel 86; One can be driven by this stretcher and the chain sprocket drive group (scheming not shown) to trailing wheel 85 (or front-wheel 86) by transmission of power; An and brake gear (scheming not shown) etc.
As shown in Figure 1, as by this first pipe fitting 10 towards the interior movement of this second pipe fitting 20, to shorten the length of this telescopic tube assembly 13, and while this first pipe fitting 10 and the second pipe fitting 20 being locked in to this shortening position by this at least one registration device 29, make the wheelbase of 85 of front-wheel 86 and trailing wheels along with telescopic tube assembly 13 shortens and diminishes; And because having an angle of inclination and front-wheel 86 and trailing wheel 85, this telescopic tube assembly 13 must be contacted with on the ground 92 of level, therefore when forward and backward two axles distance diminishes; Be connected to the seat pipe 81 at these telescopic telescopic tube assembly 13 two ends and the angle of inclination of head tube 83 also diminishes to for example between 69-71 degree thereupon.When the wheelbase that front-wheel 86 and trailing wheel are 85 diminishes, be applicable to the pattern that drives of city, metropolitan area car low speed, because wheelbase is short, make the horizontal throw of 83 of seat pipe 81 and head tubes shorter, therefore while driving, can draw oneself up and drive, traveling comfort is better, for common people compared with indefatigability; And because front fork stem 84 forward leaning angles and seat pipe 81 angles of inclination diminish to for example between 69-71 degree thereupon, the vibrations of the ground resilience that is dispersed, make earth shock be not easy to be directly communicated to handlebar, so traveling comfort are better; Allow rider's center of gravity move simultaneously more backward, while making descending or emergency brake, the situation of overturning before be difficult for producing, and it is controlled flexibility ratio and also becomes comparatively sluggish, but drive comparatively stable.
As shown in Figure 2, as being carried to this second pipe fitting 20, outwards moves by this first pipe fitting 10, to elongate the length of this telescopic tube assembly 13, and while relying on this at least one registration device 29 that this first pipe fitting 10 and the second pipe fitting 20 are locked in to this elongation position, make the wheelbase of 85 of front-wheel 86 and trailing wheels along with telescopic tube assembly 13 extends and strengthens, upper pipe distance also and then lengthens simultaneously; And because having an angle of inclination and front-wheel 86 and trailing wheel 85, this telescopic tube assembly 13 must be contacted with on the ground 92 of level, therefore be connected to the seat pipe 81 at these telescopic telescopic tube assembly 13 two ends and the angle of inclination of head tube 83 and be for example also enlarged between 73-75 degree thereupon, the pattern that drives of the car suburb high speed that is applicable to competing for speed.When the wheelbase that front-wheel 86 and trailing wheel are 85 strengthens, the personage that can be suitable for higher height drives, the pattern that the posture that also can be applicable to bending drives at a high speed; When the wheelbase that front-wheel 86 and trailing wheel are 85 strengthens, simultaneously seat pipe 81 also strengthens with the angle of inclination of head tube 83 and front fork stem 84 thereupon, and head tube, front fork stem forward leaning angle strengthen, and can obtain sensitiveer handling, seat pipe angle of inclination is strengthened, and can facilitate the more efficient application of force of trampling of rider.
For the clear difference showing between Fig. 1 and Fig. 2, refer to Fig. 3, in the trailing wheel 85 of bicycle, be positioned in the situation of same position and same level height, when solid line represents that telescopic tube assembly 13 is elongated, the relative position of each frame tube and angle; When dotted line represents that telescopic tube assembly 13 is shortened, the relative position of each frame tube and angle.By the comparison arranged side by side of solid line and dotted line, be easier to understand when telescopic tube assembly 13 is flexible the variation situation of the bicycle frame structure of this capable of regulating vehicle frame length and angle.This telescopic tube assembly 13 is shorter, and the angle of inclination of this pipe 81, head tube 83 or this front fork stem 84 is less; Otherwise this telescopic tube assembly 13 is longer, the angle of inclination of this pipe 81, head tube 83 or this front fork stem 84 is larger.
Refer to Fig. 4, the bicycle frame structure of capable of regulating vehicle frame length provided by the utility model and angle can be used in an Electrical Bicycle, its embodiments possible is on the vehicle frame of for example shelf 93, to install a rechargeable battery 94, and on the wheel shaft of trailing wheel 85, install one and take turns arc motor 95, rely on an electric control unit (scheming not shown), the electric power of rechargeable battery 94 is delivered to this and takes turns arc motor 95, to drive this bicycle walking.Electrical Bicycle, when driving, can be selected the output of complete electric power or electric boosted pattern, or the PTO Power Take Off pattern of selecting strength of one's legs to trample, when power drain, more can only select to trample with strength of one's legs.Above-mentioned three kinds of situations, for rider, are the diverse patterns that drives, and therefore optimal vehicle frame angle also should be different; Yet the Electrical Bicycle peddled on the market at present, but can only will be suitable for above three kinds of patterns with single vehicle frame, is not very desirable simultaneously.Three kinds of different patterns that drive of Electrical Bicycle are below described respectively:
Under the pattern of electric power output, rider does not need to trample completely completely, and bicycle rotatably advances, as driven motor bike.Under this kind of pattern, because rider does not need to trample, therefore do not need larger seat pipe 81 angles, with footedness, step on the application of force, so be not suitable for the angle that drives of sport car; Now to stress comfortable, need to select the angle that drives of city car, therefore shorten forward and backward two axles apart from allowing both hands can hold easily handlebar 90, make seat pipe 81 and front fork stem 84 angles more tilt simultaneously, except making center of gravity moves relatively afterwards, also more not understand front overturning.
Under electric boosted pattern, rider does not cost trampling of power, and bicycle rotatably advances.Under this kind of pattern, rider needs pin to trample, but does not cost trampling of power, is therefore also not suitable for seat pipe 81 and front fork stem 84 that sport car is larger and drives angle; Now equally to stress comfortable, need to select the angle that drives of city car, under this kind of pattern, its forward and backward two axles is apart from amplifying a little than the forward and backward two axles distance of complete electric power output mode again, make seat pipe 81 and front fork stem 84 angles add larger simultaneously, except allowing rider be easy to pin, step on the application of force, also allow both hands can hold easily handlebar 90 simultaneously.
The pattern that PTO Power Take Off selects strength of one's legs to trample, or when power drain, can only select could rotate and advance with strength of one's legs treadled cycle.Now, this Electrical Bicycle is completely identical with Regular Bicycle, generally like at a high speed by bike or to user of imposing stature, must adjust forward and backward two axles apart from extremely maximum, strengthen seat pipe 81 and front fork stem 84 angles simultaneously, make to become the angle that drives of car of competing for speed, strengthen seat pipe 81 angles and tread power with footedness; The posture that maximum wheelspan is dived, reduces windage, two-wheeled rotator inertia preferably in front and back when enjoying bicycle and driving at a high speed; And select larger forward leaning angle preferably handling to obtain.
