Description

High speed bicycle for tourism purpose with double driven mechanism

The utility model 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 application numbers 90200313.5 is invested patent on September 25th, 1991) and " chair type double-driving bicycle " (application for a patent for invention numbers 93100028.9; Utility application numbers 93200054.1) improves a kind of novel three-wheeled passenger-cargo dual-purpose high-speed bicycle that improves and design on the principle basis.

No matter in the mankind's transport development history or daily life, come a bicycle driven status of being occupied can not be ignored by manpower.Since self-moving vehicle 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 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, coming discussion work aspect the dessert machine motor vehicle about how in wide as far as possible scope, making full use of the bicycle and the free of contamination vehicle of this class low energy consumption of manual tricycle, having had increasing essentiality and realistic meaning.

As the three-wheel vehicle of one of main branch in the self-moving vehicle system and since it than two-wheeled voluntarily bicycle further increased the manned loading function of self, so in the human lives, serving as a very important role always.Especially in recent years the family expenses light tricycle of Chu Xianing, under the prerequisite that guarantees manned loading function, possessing characteristics such as light and flexible simultaneously again, very convenient and practical, so more and more be subjected to the welcome and the favor of numerous domestic family, even abroad, its very wide demand market is arranged also.

Though existing self-moving vehicle (no matter be bicycle or three-wheel vehicle) is voluntarily possessing on record multiple preceence, also exist many obvious defects and the unreasonable part of design inevitably, 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 and three-wheel vehicle rides appearance and must adopt posture with one's back bent, the mistake of the human physilogical characteristics of this obvious violation is ridden appearance not only can cause waste on the manpower function, and very easily make people's fatigue, long-distance ride especially true.And three-wheel vehicle strengthens owing to the each side load, and all drawbacks of bringing thus are just more outstanding.

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 walking or run jumping the systemic movement of class, its four limbs can instinct done the interlaced coordinated movement of various economic factors.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 or by tricycle, ought to be a kind of motion of general.But because standard bicycle and three-wheel vehicle design are unreasonable, the driver 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, and the work efficiency that can reduce shank on the contrary increases 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 or three-wheel vehicle.

3, center of gravity height, dangerous: standard bicycle and three-wheel vehicle are 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 driver 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 running into sudden situation, just very easily lead to traffic accident.

4, saddle construction is harmful: the vehicle seat of standard bicycle and three-wheel vehicle mostly area is less than normal and triangular in shape, certainly will make the people 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 by bike the 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 improve trend with development from the bicycle of our times and three-wheel vehicle, the development main flow of relevant bicycle improvement aspect 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.Aspect the relevant speed of a motor vehicle that how further to improve bicycle and three-wheel vehicle, some improvement such as chain gear being changed into gear transmission or drum drive really also once appearred.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 scope of " voluntarily " vehicle already.Again from the manual tricycle function aspects of current popular, mostly or holding or loading function singleness, use limitation very strong.For the three-wheel vehicle of special holding, its functional limitation is then more outstanding.No matter for example when three-wheel vehicle or be positioned at driver on the operator's saddle under which kind of situation, the passenger on the car can only single sitting quietly and can not make complementary operation of the least bit and processing to the driving or the braking of three-wheel vehicle.So just do not caused the waste on drive people and the rider's muscle power physical efficiency, and the decay of the mechanical advantage index of three-wheel vehicle own, and also the utmost point is unfavorable for the safety of driving a vehicle.Generally speaking, from present case,,, all be very necessary no matter also be in their structure design or the improvement of function aspects no matter be aspect bicycle or aspect manual tricycle.

The purpose of this utility model is: according to designing a kind of comprehensive advantage that had both kept standard bicycle and three-wheel vehicle about basic mechanics of machinery, body mechanics and aerodynamics etc. about theory, meet simultaneously the physilogical characteristics of human motion again and can save muscle power significantly and the raising speed per hour, safety and comfort, the many usefulness of one car, and the utmost point is of value to the two passenger-cargo dual-purpose high speed three-wheel vehicles that drive of driver's brand-new type healthy and that make it to feel full of interest.The utility model principal feature one is the new-type seat support that the triangle saddle of traditional three-wheel vehicle is changed into the band backrest, and height reduces significantly than traditional three-wheel vehicle.Driver's 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, makes driver's coordinated movement of various economic factors of can using both hands and feet when driving.By above-mentioned change three-wheel vehicle structure design with change tradition mode or the like approach of driving, reach the purpose that guarantees that the driver saves muscle power and the speed of a motor vehicle is improved significantly significantly under comfortable safe prerequisite; The 2nd, be the loading space of traditional three-wheel vehicle function singleness or visiting comprehensive Design later-model passenger-cargo dual-purpose compartment, promptly just can make the compartment reach the purpose that can be used for holding or loading according to user's needs as long as adjust slightly.Set up at the suitable position of car body again in addition and aimed at complementary system and the brake system of driving that the passenger uses, so that make the motroist under necessary or interesting situation, can indiscriminately ad. as one wishes help the driver to drive or brake.Thereby make the utlity model has comfortable, laborsaving, at a high speed, safety and multiple good effect such as make us feeling to brim over interest.
