Description
Technical field
The present invention relates to a kind of easy lifting bicycle saddle, belong to bicycle accessories manufacture field.
Background technology
When bicycle is ridden fast or ridden at a distance, need higher location of saddle support, jockey bends to ride, and shank can stretch, and is convenient to lower limb and has an effect and save muscle power, and reduce windage.But saddle lower during descending can lower the center of gravity, guarantee riding safety.Or when leisure is ridden, lower saddle maintains honest sitting posture, reduce shoulder and lumbar vertebrae is stressed, obtain comfortable experience.Therefore, a kind of technology that is easy to adjust bicycle saddle height in riding highly significant.
Known bicycle saddle is generally inserted into vehicle frame sitting tube end, according to circumstances adjusts after suitable and maintains static.Even if having quick-disassembly structure, after also must getting off, loosening fasteners could be adjusted saddle height, is difficult to change height in riding.Using controllable gas spring as jacking system, is the good method of adjusting at any time saddle height.Gas spring is mainly comprised of the pneumatic tube being mutually nested and piston rod, and the piston by piston rod one end in pneumatic tube is divided into two air chambers, and is filled with high-pressure inert gas.Conducting air chamber, because two air chamber air pressure equate, to the active area of piston not etc., gas produces outward thrust to piston rod, impels gas spring to extend.The large I of thrust is set by different air pressure or diameter of piston rod are set.Exert pressure and can make gas spring shorten in outside; Can locking gas spring length and close upper and lower air chamber circulation.
Patent CN202703759U and CN203450245U adopt the technological means that clamps controllable gas spring on sitting bar to realize bicycle saddle lifting, can in riding, change arbitrarily the height of saddle.But the smooth and easy slip of gas spring for assurance air-tightness and axially, adopts circular pipe as member body conventionally.Aforementioned two problems that technical scheme exists saddle along the circumferential direction to rotatablely move in the process of riding.
The same gas spring structure of using realizes saddle capable of lifted, and patent CN202896743U and CN201677996U are used non-circular guide rod to avoid saddle circular-rotation; Patent CN1424219A adopts increases the problem that the technical scheme of confinement groove solves saddle rotation.Use abnormity component likely the air-tightness of gas spring to be impacted, and increase manufacture difficulty, working accuracy is also had high requirements.And the control handle that patent CN1424219A is arranged on Pillar for saddle has limited the angular adjustment of saddle circumferencial direction and the adjustment of saddle front and back height.
In addition, use gas spring to realize lifting, in order to guarantee to be close to linear elastic curve, conventionally use the more tiny piston rod in cross section.At this moment, even if piston rod can bear bicyclist's weight, but often stressed in actual conditions be not vertical direction, and because the reasons such as road jolts produce great momentum, tiny piston rod is as easy as rolling off a log to fracture, and causes Peril Incident.
Summary of the invention
For above-mentioned problems of the prior art, in conjunction with this body structure of bicycle, based on gas spring principle, the present invention's design is applicable to unique lifting mechanism that bicycle saddle is adjusted, and proposes a kind of without the just easy lifting bicycle saddle of energy quick adjustment height of getting off.
The technical solution used in the present invention is:
A kind of easy lifting bicycle saddle, comprise cushion, Pillar for saddle and lifting mechanism, described cushion is fixed on Pillar for saddle, Pillar for saddle is clamped in the upper end of described lifting mechanism, it is characterized in that: described lifting mechanism has: urceolus, it consists of cycle frame sitting pipe, and upper end is provided with seal cover cap, makes to cut off external pressure; Lifting tube, it inserts in described urceolus; Bottom center has square hole; Lower end is provided with piston, and described piston is separated out upper chamber and lower chamber by described urceolus; Inner piston rod, it inserts lifting tube bottom square hole from top, and lower end and urceolus bottom are connected and fixed; Inner piston rod upper end has piston, and described lifting tube and external pressure are cut off.
By urceolus, lifting tube, piston rod, form the essential structure of double-piston gas spring, thereby utilized controllable gas spring principle to realize saddle capable of lifted.Compared with prior art, in the present invention, the major part of lifting mechanism is all concealed in vehicle frame sitting pipe, outer shape has still kept the architectural feature of Regular Bicycle, can not cause other harmful effects to bicycle performance, such as various aspects such as the adjustment of saddle front and rear angles, bicycle monnolithic cases.
Further, described lifting tube lower end is provided with pore, makes lifting tube inside and lower chamber conducting.The piston on inner piston rod top is by lifting tube and large gas barrier, conducting lifting tube and lower chamber can avoid the lifting of saddle to cause the total inner product of air chamber to have greatly changed, thereby guarantee that gas spring structure is close to linear elastic curve, still can guarantee locked ability when making saddle have larger range.Therefore, the structure of double-piston can make lifting tube have larger size also can not affect the elastic curve of gas spring structure, thereby can guarantee that bicycle frame can have needed sufficient intensity.
Further, described urceolus is provided with communicating pipe, and described communicating pipe is arranged on the side of described urceolus, makes upper chamber and lower chamber conducting.Two necessary conductings of air chamber in controllable gas spring structure, thus to adjust air chamber relative volume, change overall elongation, realize saddle capable of lifted.Side is established communicating pipe rather than is added conducting structure in urceolus inside, makes outer tube structure keep complete, can guarantee frame strength, and avoid complicated manufacturing process.Meanwhile, the members such as air valve, valve are conveniently set, can simplify integral structure, reduce costs.
Further, described urceolus is provided with air valve, and described air valve is positioned at communicating pipe lower end, and the gas circuit of controlling communicating pipe opens and closes.Control air valve opens and closes, and can switch the locking state of lifting mechanism, realizes saddle capable of lifted.Press air inlet valve, communicating pipe gas circuit open, bicyclist lifts buttocks, lifting tube naturally rises under the condition without External Force Acting, saddle is raised; And work as bicyclist, sit down, applied external force is greater than gas pressure, and lifting tube landing, installs and reduce.After air valve lifts, gas circuit is closed, and lifting mechanism is locked.
Further, also comprise control lock, it is fixed on the handlebar of bicycle; And be connected with described air valve by brake cable.By the control lock of handlebar, control air valve and open and close, adjust at any time the lifting of saddle, the regulative mode of saddle is consistent with the mode of brake, driving speed change, makes bicycle have good controller performance.And, because air valve is arranged on communicating pipe lower end but not on cushion, brake cable is easy to connect.
Further, described urceolus is provided with valve, and described valve is positioned at the upper end of communicating pipe.Be provided with valve, according to actual conditions, can adjust at any time air chamber air pressure inside, thereby obtain suitable coupling mechanism force.
Further, valve adopts the identical structure of vehicle tyre valve of assembling, and lifting mechanism can adopt the method for gas injection of tire, without need special gas injection means as conventional gas spring.
Further, the section of inner piston rod is square, matches with the square hole of described lifting tube bottom.Because piston rod is fixed on urceolus, lifting tube place nested with inner piston rod is square, and the rotation of circumferencial direction can not occur lifting tube.And this makes to support stressed lifting tube can use high-intensity cylindrical structure; And square pole is also the common structure of metallic material, without special processing.
Further, described piston bush has O type circle; Between seal cover cap and urceolus, be lined with O type circle; Between seal cover cap and lifting tube, be lined with O type circle.Due to air chamber sealing, place is circular configuration, can use O type circle as gas seal member.O type circle is conventional obturator, cheap, durable, and can guarantee good air-tightness.
Further, be filled with the unreactable gas of purity >90% in described lifting mechanism, atmospheric pressure value is 400-480kPa.Unreactable gas is difficult for reaction, uses it as pressure gas, avoids high pressure lower chamber to blast, and guarantees the safety durable of gas spring structure.And when in air chamber, air pressure is higher, gas spring coupling mechanism force is stronger; And suitably reduce the unreactable gas air pressure in lifting mechanism, can obtain the damping effect of saddle simultaneously.
The present invention is in conjunction with bicycle structure feature, by designing new gas spring structure, realizes the adjustment of saddle height in the process of riding, and solves saddle capable of lifted this problem of need to getting off; And avoid the problem of gas spring circular-rotation in prior art; Use dual-piston structure to guarantee that the primary structure members such as urceolus, lifting tube have enough sizes, thereby reach strength demand; Can control lock by handlebar and directly control saddle capable of lifted, convenient, flexible, improved the efficiency of riding, and made bicyclist obtain the experience of better riding.

The specific embodiment
Below in conjunction with accompanying drawing, easy lifting bicycle saddle in the present invention is described further:
Fig. 1, for being easy lifting bicycle saddle schematic diagram in the present invention, comprises cushion (a), Pillar for saddle (b) and lifting mechanism (c); Fig. 2 is the concrete structure schematic diagram of lifting mechanism (c) wherein, and its inner high-pressure inert gas that injects, forms controllable gas spring structure, thereby can realize the lifting of saddle.
Shown in figure 2, can first check the air valve (c9) of urceolus (c2) bottom and the structure of valve (c6) is intact above, and can normally work.The structure of valve (c6) is consistent with the tire valve of assembled bicycle.Air valve (c9) comprises needle, connection brake rod from urceolus inside passes; Brake rod is bound by brake cable (c11) and is connected and controls lock, controls lock and is fixed on straightgoing vehicle handlebar.On brake cable, cover has Compress Spring (c10), withstands brake rod, keeps needle in lifting status, and now (c7) gas circuit is closed communicating pipe; When clutching control lock, by the drop-down brake rod of brake cable, needle is pressed into, and now (c7) gas circuit is opened communicating pipe; Unclamp control lock needle lift, gas circuit is closed.
The piston of inner piston rod (c4) is inserted in to O type circle, and piston is upper, and from the uncovered insertion in lifting tube (c3) upper end, the square hole of Bing You lifting tube bottom centre passes.
The piston of lifting tube (c3) lower end is inserted in O type circle equally, together with inner piston rod (c4), carefully inserts urceolus (c2), and lifting tube piston is separated out upper chamber and lower chamber by urceolus.
Inner piston rod (c4) is pushed into urceolus bottom fixing.Because inner piston rod (c4) is not main primary structure member, only need to guarantee that it circumferencial direction can not occur and rotates, can use latch (c12) that it is fixedly connected with urceolus (c2).
Urceolus (c2) upper end is encased inside O type circle; Seal cover cap (c1) inside is encased inside O type circle, from be inserted in lifting tube (c3) upper end, screws in urceolus (c2), completes sealing.
For increasing lubricated and air-tightness, before assembling, can between member, partly drip moderate lubrication oil by relative sliding, on piston place and the inner carrier body of rod.
Fig. 3 is the section drawing in the stage casing of lifting mechanism.Outside is urceolus (c2), and centre is lifting tube (c3), and interior is the inner piston rod (c4) of square-section, and side is communicating pipe (c7).Wherein urceolus (c2), lifting tube (c3), communicating pipe (c7) are circular tube structure.Fig. 4 is fall way bottom position place, the section drawing of lifting mechanism.The square hole that lifting tube (c3) low side middle part has and inner piston rod (c4) size is mated, can guarantee that lifting tube slides up and down and can not circular-rotation.Square hole side is provided with pore, makes the lower chamber conducting of lifting tube inside and urceolus.
Lifting mechanism (c) completes after assembling, and it is upper that cushion (a) is fixed on Pillar for saddle (b), and Pillar for saddle (b) is clamped in the upper end of the lifting tube (c3) of lifting mechanism (c), as shown in fig. 1.
Saddle completes after overall package, checks that each parts connect normal, and from valve (c6) inert gas injecting, air pressure is controlled at 450kPa left and right.Observe and whether have gas leak phenomenon.If gas leakage need be taken each parts apart from valve (c6) venting, check the positions such as O type circle, get rid of connection error.Suitable adding machine wet goods leak tightness grease, more again complete assembling.
Each member of lifting mechanism connects normal, good seal, and inside is marked with high-pressure inert gas, and bicyclist is sitting on saddle, by the air pressure balance of body weight and lifting mechanism, can realize the controllable adjustment of saddle height.
Clutch control lock, air valve needle is pressed into, and now (c7) gas circuit is opened communicating pipe, and upper chamber and lower chamber are connected state, and 2 air chambers air pressure equates.Bicyclist lifts buttocks, and in vertical direction, lifting tube is subject to the effect of lower chamber air pressure, upper chamber air pressure and external pressure simultaneously.Because lower chamber gas pressure Area Ratio upper chamber active area is large, i.e. lower chamber air pressure thrust > upper chamber thrust; And be times over atmospheric high pressure gas in air chamber, barometric pressure effect can temporarily be ignored, thereby lifting tube is subject to thrust upwards, can slowly lift the position rising of bicycle saddle.
Unclamp control lock, air valve needle lifts, communicating pipe gas circuit close.Now, the air pressure of upper chamber and lower chamber is no longer equal, when lifting tube rises again upper chamber by compression, smaller volume, air pressure increases, until produce enough downward thrust and lower chamber balance.Thereby now lifting tube position does not change, realize saddle height locking.Even if bicyclist is sitting on saddle, lifting tube is produced to downward pressure, by compression, gas pressure intensity increases lower chamber, upwards thrust increases, until with bicyclist's body weight balance.In lifting mechanism air chamber, air pressure is larger, and the locking ability of generation is stronger.
While reducing saddle, clutch control lock, open connection gas circuit.Now bicyclist occupies stably on cushion, and lifting tube vertical direction has been subject to the downward pressure that bicyclist's body weight causes simultaneously.This pressure wants large compared with air pressure thrust, and lifting tube declines, and saddle declines.Gas in lower chamber is transferred to upper chamber while being compressed, air pressure can obviously not strengthen.Unclamp and control after lock, saddle height relocks, and adjustment completes.Thus, the control lock that bicyclist only need brake on handlebar can easily be adjusted saddle height, simple and convenient, and bicyclist can easily experience the different effects of riding.
Specific embodiment described above is only to the present invention's explanation for example.Those skilled in the art can make various modifications or adopt equivalent way to substitute, but can't depart from spirit of the present invention or surmount the defined scope of appended claims.
