Fig. 2 is the transmission structures schematic diagram of bicycle in the utility model.
Fig. 3 is the driving device schematic diagram.
The specific embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, clear and definite, referring to the accompanying drawing embodiment that develops simultaneously, the utility model is further described.
The utility model discloses a kind of bicycle, as shown in Figure 1, be applicable to the disadvantaged group such as aging crowd and residual arm, specifically comprise vehicle frame, be arranged on the front tourelle that arranges before and after bottom of frame and rear tourelle (in the present embodiment, described tourelle is wheel, specifically comprises two front-wheels 210 that are set up in parallel and two trailing wheels 220 that are set up in parallel), driving device and steering hardware; Seat 110 is installed on described vehicle frame; Described two groups of wheels comprise between two front- wheels 210 and 220, two front-wheels 210 of two trailing wheels and are provided with between 230, two trailing wheels 220 of tie rod and are provided with trailing wheel pipe link 240; Described steering hardware is connected with the tie rod 220 of front-wheel 210.In actual applications, described driving device is two quadric linkages that are arranged side by side; As shown in Figures 2 and 3, described quadric linkage comprises crank 310, connecting rod 320 and rocking bar 330; Described crank 310 is connected with trailing wheel pipe link 240, and two cranks 310 symmetry respectively are connected on trailing wheel pipe link 240, and two cranks 310 are 180 °, and rocking bar 330 is fixedly connected with tie rod 230, connecting rod 320 connecting cranks 310 and rocking bar 330.
Compare type of drive numerous in theory of machines by analysis, and with reference to the motion principle of the various mechanisms that exist in reality, the utility model selects quadric linkage as driving device, for bicycle provides power, quadric linkage is simple in structure on the one hand, be easy to realize, quadric linkage more is applicable to the disadvantaged group such as aging crowd and residual arm than traditional chain drive on the other hand.But there is certain problem in quadric linkage: i.e. dead center position.Quadric linkage is referred from manually stirring of operator when sewing machine is applied, thereby turns over dead center position, then by inertia, makes wheel continue rotation, avoids two dead points.If be applied to bicycle, the operation that uses the same method, can seem loaded down with trivial details, uses very inconvenient.In order to solve problem how to avoid dead center position, the contriver is by observing, analyze and experiment, and the balance of exerting oneself according to the people, consider that the user uses the both feet operation more comfortable, use the driving device of two quadric linkages as bicycle, and two cranks 310 symmetry respectively are connected on trailing wheel pipe link 240, present 180 °: if when one of them quadric linkage enters dead center position, can't continue to step on, now drive the another one quadric linkage, because second quadric linkage not yet enters dead center position, therefore, can drive rotation of wheel, after the normal rotation of wheel, inertia due to wheel, dead center position can be avoided.This setup can perfectly realize that two quadric linkages coordinate wheel to do cyclical movement, meet the rotation requirement of cycle wheel.
Novel for more user-friendly implementation, adaptation user's use habit, be provided with foot-operated 340 on described rocking bar 330.In practical application, the user controls rocking bar 330 periodic oscillations for two foot-operated 340 by trampling of repeatedly replacing, thereby control the cycle wheel cycle, rotates.
In addition, consider the characteristics of the disadvantaged group such as aging crowd and residual arm, if adopt traditional two to take turns design, the elderly is difficult to guarantee the steady of bicycle at complex environment, therefore, the utility model adopts the four-wheel design, reduces the probability that the user meets accident at various complex environments.But the utility model also can be taken turns design for two, specifically arranges and need to select according to user's actual needs.
Further, in order to increase practicality of the present utility model, improve the safety that the user travels at night, described bicycle also comprises the car light 600 that is arranged on the vehicle frame front end.
Further, in order to increase practicality of the present utility model, improve the safety that the user travels,, described bicycle also comprises the screened housing 120 that is arranged on two brake gears on trailing wheel and is arranged on protection vehicle frame on vehicle frame.
Further, in order to increase practicality of the present utility model, described bicycle also comprises the reversing face 500 of the screened housing front end be arranged on vehicle frame.
Further; for the disadvantaged group such as the convenient aging crowd of the utility model and residual arm are used, described seat is provided with backrest, is provided with protective cushion on described seat; described steering hardware is bearing circle 410, and described bearing circle 410 is connected with tie rod by rotating shaft.
Should be understood that; application of the present utility model is not limited to above-mentioned giving an example; for those of ordinary skills, can be improved according to the above description or convert, all these improvement and conversion all should belong to the protection domain of the utility model claims.
