Description

Chair type double-driving bicycle

The invention belongs to the vehicle, be my former object of invention " man-driven high-speed sedan " (application for a patent for invention numbers 89109215.3, open on June 26th, 1991; Utility model application numbers 90200313.5 was granted patent on September 25th, 1991) and " dual-driven high-speed bionic bicycle " (application for a patent for invention number 92105865.9) principle basis on improve a kind of novel two-wheeled high-speed bicycle that improves and design.

On human science and technology developing history, bicycle can be rated as the invention of a greatness.Since bicycle have unique and impayable convenient and practical, economize the energy, pollution-free, floor area is little, and the advantage of cheap or the like all many-sides.The side makes it not only can be in fashion a kind of vehicle that the world becomes the human quantity maximum that was had, and can the time through twoth century and long lasting.Even in today of the industrial high development of modernization and in quite long from now on period, the vehicle that driven by manpower still will play the vital function that it can not be substituted.Especially under the situation that the worldwide public hazards such as energy shortage environmental pollution that current mankind faced are on the rise, in wide as far as possible scope, make full use of the human good hope that the free of contamination vehicle of this low energy consumption of bicycle come the dessert machine motor vehicle, then further show its essentiality and urgency.

Though bicycle is possessing on record multiple preceence, also still exist inevitably many obvious defects with the design unreasonable part, some or even demand improved critical problem urgently.Roughly conclude and be:

1, structure design is improper: the Structural Design Requirement people of standard bicycle rides appearance and must adopt posture with one's back bent.And the incorrect posture of the human physilogical characteristics of this obvious violation is accompanied by the appearance of bicycle and year is not altered under any circumstances and continues into the present surplus competing to experience 200, really makes us feeling inconceivable.The riding appearance and not only can cause waste on the manpower function of this mistake, and very easily make people's fatigue, long-distance ride especially true.

2, do not meet the physilogical characteristics of human motion, energy dissipation is big: from angle of physiology, when the mankind when doing such as the walking or the systemic movement of saltaroria, its four limbs can be done the coordinated movement of various economic factors of interlaced ground by the light of nature.So just can make the bodily fuctions obtain normal and performance fully.If want the motion and the cooperating of on the go restriction upper limbs, then not only can greatly influence its motor function, and can cause and quicken the fatigue of health significantly.Originally being substituting or continuity of human walking or running behavior by bike, ought to be a kind of motion of general.But because the standard bicycle design is unreasonable, the person of riding can only be fixed in both arms on the handlebar in the process by bike always.Two arm functions can't normally be brought into play, can reduce the work efficiency of shank on the contrary and increase the fatigue of general.No matter in addition theoretically or having proved all that the mankind only can drive with upper limbs power in the practice self advances.No matter so which aspect, the routing motion of restriction upper limbs all can't but be a kind of huge physical physical efficiency waste in by bike.Moreover thisly with one's back bent ride appearance advancing air resistance is obviously increased, thereby greatly have influence on the speed of advance of bicycle.

3, center of gravity height, dangerous: standard bicycle is because this body structure is limit, and its vehicle seat has to design higher, and mostly both feet can't kiss the earth after making the person of riding take vehicle seat.The higher consequence of bringing of center of gravity is said except that above-mentioned institute and is increased the air resistance like this, also brought simultaneously such as poor stability, and safety hazard such as the inconvenience of getting on or off the bus, when meeting sudden situation, just very easily lead to traffic accident.

4, saddle construction is harmful: standard bicycle vehicle seat mostly area is less than normal and triangular in shape, the trend that existing popular derailleur, mountain bike etc. more have the seat surface mouth to become to reducing.Certainly will the person who happens to be on hand for an errand by bike the time, have to whole body weight is concentrated on the narrow and small trigonum of perineum part and makes this position be subjected to serious extruding for a long time like this.In the course of time, will play the organic disease of some organ of Genitourinary, its harm is particularly serious for the elderly and women.And so on.

As if from the bicycle improvement and the trend that develops of our times, its development main flow is to work hard on the materials of vehicle body and assortment.The improvement project that has functional, essence is then as phoenix feathers and unicorn horns.How further to improve aspect the speed of a motor vehicle relevant, some improvement such as chain gear being changed into gear transmission or drum drive really also once occurred, also having some then is auxiliary facilities of setting up on bicycle DC motor or combustion engine and so on or the like.And on reality, the improvement that only belongs to minor matters that above-mentioned suchlike improvement has does not have great practical significance.Then being still that other has developing to the motorization direction, do not belong to the investigation category of " voluntarily " car already.So in very long one period up to now, about the reform of bicycle and the work of innovation aspect are in a kind of standstill state that fluctuates always, its rhythm lags behind the high speed development of current science and technology greatly, does not satisfy the global social demand more and more higher to bicycle far away.

The present invention is exactly at above-mentioned situation, a kind of whole advantages that both kept standard bicycle of design-calculated according to relevant theory such as relevant basic mechanics of machinery, body mechanics and aerodynamics, meet simultaneously the physilogical characteristics of human motion again and can save muscle power significantly and the raising speed per hour, safety and comfort, cheap, and the utmost point is of value to the healthy new pattern high speed bicycle of driver.Its principal feature one is the new-type seat support that standard bicycle triangle saddle is changed into the band backrest, and the seat height reduces significantly than standard bicycle.The person's of riding the appearance of riding also changes comfortable back backstroke into by traditional bending waist-back type.Thereby the best when obtaining to drive is pedaled the power effect and advancing air resistance is significantly reduced, and simultaneously the safety of car and stability is strengthened greatly.Set up at the handlebar position can one hand or the f-w-d augmenter operated simultaneously of both hands for the physilogical characteristics of the staggered coordinated movement of various economic factors of trick during in addition again according to human motion.Make the person's of riding coordinated movement of various economic factors of when driving, can using both hands and feet.By the design of above-mentioned change bicycle structure with change tradition mode or the like approach of driving, to reach the purpose that guarantees that the person of riding is improved significantly the speed of a motor vehicle under comfortable laborsaving and safe prerequisite.

Among Fig. 5 31 is the marshall springs support plate.

The implementation process itemize is described below:

1, back-wheel drive: the back-wheel drive mode and the standard bicycle of chair type double-driving bicycle are basic identical.Different persons are the processes of pedaling that help that reduced when riding standard bicycle, specific procedure can directly be seated at (this moment, both feet can all land) on the car seat support 4 for the person of riding, both hands are held handlebar 2, play a foot-operated moving pedal 7, and drive pedal crank 8 thus and rear drive hinge wheel 9 is rotated forward and rear flywheel 11 is rotated in the same way, thereby change before driving rear wheel 6 by rear drive chain 10.Both feet so take turns to step, and bicycle promptly marches forward.

2, f-w-d (reinforcing):

F-w-d is that afterburner process can be divided into both hands and singlehanded two kinds of afterburning operating mode of driving according to the person's of riding ripe refining degree.

The bimanualness mode is that the person of riding is seated at two hands on the car seat support 4 and holds the preceding afterburning handle 12 at handlebar 2 two ends respectively and rotate in the same way forward in the mode that replaces mutually, preceding afterburning crank 13 by two ends rotates the preceding afterburning hinge wheel 14 that right axial region is fixed in 20 drives of handlebar center shaft in the same way, and flywheel 18 drives front vehicle wheels 3 and rotates forward before making by preceding afterburning driving chain 15, and finishing f-w-d thus is power-assisted overall process.

The one-handed performance process is that left hand is held left pipe 22 of the handlebar of captiveing joint with handlebar center shaft bearing seat 21, the afterburning handle 12 that the right hand is held handlebar 2 right-hand members rotates forward, all the other mechanical transmission courses and bimanualness process are identical, and finish the singlehanded power-assisted operating process that drives thus.

At f-w-d is in the afterburner process, and no matter by both hands or by one-handed performance, handlebar center shaft bearing seat 21 is in pipe 22 in the state of static rather than rotation all the time with a handlebar left side of captiveing joint with it.

According to the relevant principle analysis of mechanics of human motion, both hands and both legs participate in driving motion simultaneously not only can lack of equilibrium, and it is more stable with condition that bicycle is advanced, and confirms that through practice conclusion is as the same.

Consider relevant turning to, a reason such as moulding, front vehicle wheel diameter of the present invention is generally less than rear wheel.

3, turn to

Moving track is the horizontal direction rotation owing to row in handlebar 2 of the present invention its two ends when turning of bicycle; and the path of motion of afterburning handle 12 is to be the vertical direction rotation in the center of circle with handlebar center shaft 20 before in before driving of the present invention (reinforcing) process; two kinds of rotational trajectories do not disturb mutually; so two kinds of functions that handlebar 2 of the present invention has before driving (reinforcing) simultaneously concurrently and turns to confirm that through practice conclusion is as the same.

4, the car seat position is adjusted

For adapting to the difference of each side condition such as the difference person of riding height, before and after car seat support 4 of the present invention is designed to do as required or the suitable adjustment of height direction.Its component function is: adjust the high low degree of car seat support with standpipe 27 by improving or reduce the adjusting height; Adjust the front and back position of car seat support 4 by regulating the front and back position of binding bolt 29 in front and back adjusting bracket 28.

Brake system of the present invention is identical with existing bicycle.

Of the present inventionly increasing front and back wheel and, also can be designed to three-wheel passenger and freight car or three-wheel and four-wheel sedan-type cycle about principle and structure design according to increasing on the required basis of adjusting relevant transmission shaft and other corresponding drive mechanism of front and back wheel.

The present invention compared with prior art has the following advantages and good effect:

1, meets the human motion physilogical characteristics, laborsaving, efficient is high: because type of drive of the present invention is the four limbs coordinated movement of various economic factors, meet the human motion physilogical characteristics, thereby decapacitation reduces in the process of riding outside the physical efficiency waste significantly, also can pedal the power effect by tradition with one's back bent being ridden appearance the best when changing into the comfortable posture of partly swinging back and riding with acquisition. The car seat back reaction force of newly establishing simultaneously also can play significantly to help to be pedaled and the power-assisted effect, thereby guarantees a large amount of savings of the person's of riding muscle power in the process of driving and the speed of a motor vehicle is significantly improved.

2, comfortable, obviously be good for one's health: the car seat back of newly establishing and the expansion of seat cushion area have all increased the contact area of human body and seat support. The decapacitation local pressure that reduces significantly health makes outside the people feels comfortably cool like this, can also effectively prevent and the generation of stopping to ride the popular what is called of standard bicycle " bicycle disease " with spread.

3, low, the safety of center of gravity:, make the person's of riding both feet on the car seat support can all step on firm ground because the car seat support among the present invention reduces significantly than standard bicycle vehicle seat height.Outside a large amount of air resistance that reduce in advancing of decapacitation, also be convenient to the driver simultaneously and indiscriminately ad. as one wishes handle various emergency case, thereby greatly improve the personal safety coefficient of the person of riding in the process of riding like this.

4, the present invention is simple in structure, and is cheap, and floor area is little, is easy to deposit, so great practical value and promotional value are arranged.

5, the present invention is having energy savings simultaneously concurrently, prevents to pollute and is of value to obviously advantage such as health, and huge social benefit and economic benefit are arranged.
