Description

Hermetic type low seat and flat pedal Manpower driver

The utility model relates to a kind of Manpower driver, particularly a kind of two takes turns, three-wheel, four-wheel hermetic type low seat and flat pedal Manpower driver.

Existing Manpower driver has two wheel bicycles, cyclo, all relies on both feet to make it to advance as circular movement.This class actuating device, it is s=π d (d is that pin turns diameter) that the pin stirrup turns back the distance of being passed by that circles along pin, the merit of being done then is w=fs '=fd (s ' for along the distance of work done direction).As seen, the people is in the process of driving, and most of power all is not utilized, and has only small part power (about 1/3) to make useful work.

The purpose of this utility model provides a kind of increase useful work, reduces idle work, makes full use of human body each side energy, has hermetic type low seat and flat pedal Manpower driver, realizes the purpose of efficient high-speed.Compare with the available man-power actuating device: laborsaving when speed is identical; Speedup when identical of exerting oneself.

Main innovate point of the present utility model has:

1, adopts hermetic type streamline contour outer cover: as shown in Figure 1, its outside light plastic streamline contour outer cover of using is wrapped the major part of vehicle body fully, makes car load have the fleetline profile, can make car when operation particularly during high-speed cruising resistance reduce 1/3～2/3, promptly speed per hour can improve about 1 times.

2, adopt low level vehicle seat band backrest structure:

Present bicycle, three-wheel vehicle seat are above the pin stirrup, when the driver steps pedal downwards, applied force generally can not surpass the weight of self, but when riding racing car, need waist is stooped, scrunch downwards with pin, just can use bigger strength, according to this principle, the vehicle seat of the utility model device be contained in the contour substantially plane of pin stirrup on, allow portrait half recumbency equally go to pedal and step on the pin stirrup near horizontal direction, simultaneously, lean against arcuate backrest, on the pin stirrup, do not need firmly many like this, just can improve speed per hour more than 1 times, as shown in Figure 2.

3, employing level is pedaled and is stepped on the formula actuating device

The driving of existing ordinary bicycle, manual tricycle is that people's both feet are pedaled and stepped on the pin stirrup and as gyroscopic movement car is advanced, and useful work only accounts for about 1/3 of total work; The utility model employing level is pedaled and is stepped on the formula actuating device, its gordian technique is the circular movement of pedal changed into and is bordering on horizontal rectilinear motion, the realization of this mode of motion is to realize by the type of drive between sprocket wheel, chain, its principle of work is: when left foot forward the application of force pedal when stepping on left side pin stirrup, the pin stirrup is rotated in the forward by left rocking bar chain drive left side sprocket wheel, power-transfer clutch is closed and make drive wheel drive the back flying wheel to be rotated in the forward, device is travelled forward on it; Meanwhile, the chain on the left rocking bar makes right sprocket wheel reverse by pulley, and right sprocket wheel power-transfer clutch and drive wheel place and released state, then right crus of diaphragm stirrup motion backward accordingly.When the left foot stirrup moves forward at the most preceding, the right crus of diaphragm stirrup moves rearwards to rearmost point, the conversion pin is stepped on direction, be that right crus of diaphragm is pedaled forward and stepped on, right sprocket wheel just changes, and drives whole device and travels forward, and left sprocket wheel power-transfer clutch separates with drive wheel, the left foot stirrup is motion backward accordingly, up to terminal point, finishes a cycle event.So repeatedly, but travelling forward continuously of implement device then.

4, summary: the utility model device is taken turns with existing common two, the three-wheel Manpower driver is compared, and has the following advantages:

1) hermetic type structure: the driver of people's power apparatus is no longer born boisterously wreck and persecute, and teardrop body can significantly reduce resistance again, improve the speed of a motor vehicle, and under the high-speed cruising state, this preceence be more outstanding.

2) low level vehicle seat band backrest structure: make Manpower driver can bring into play the firmly function of organization of human body to greatest extent, reduce people's strength at repeated alternation, strengthen driver's traveling comfort, improve driver's endurance, make its easily drive system advance.

3) flatly pedal the formula actuating device: make the harmful component in the Manpower driver significantly reduce, useful component significantly improves, and further improves driver's endurance and work doing efficiency again, has improved the kinematic velocity of system.

4) consider unit frame, selecting for use of light-duty plastic, the failure-free brake system, the stability that starting is stopped etc., can make adopt that the utility model Manpower driver makes two take turns (trailing wheel adds two auxiliary wheels), three-wheel (trailing wheel band diff), four-wheel (front-wheel band steering hardware) rickshaw as the riding instead of walk of people, transportation, the vehicle, also can be used as physical culture, body-building and amusement instrument.

Below in conjunction with drawings and Examples the utility model is further elaborated:

Fig. 1 is the utility model surface structure scheme drawing, and Fig. 2 is the low seat and flat pedal actuating device.

Embodiment: the utility model utilizes described hermetic type streamlined contour, low level vehicle seat band backrest structure, the flat bicycle of pedaling the making of formula actuating device, comprises left rocking bar 1, vehicle frame 2, right rocking bar 3, pedal 4, right bar chain 5, vehicle seat 6, backrest 7, right sprocket wheel 8, chain 9, flywheel 10, drive wheel 11, pulley 12, outer cover 13.Outer cover is fixed on the unitized frame, and vehicle frame constitutes the L type by connecting rod in the elevation profile, and the upper end is rocking bar rotating shaft center, and pedal is equipped with in the rocking bar lower end, and affixed chain drive-belt---left bar chain and right bar chain chain, and be connected as a single entity by pulley.Overriding clutch is housed respectively in the sprocket wheel of the left and right sides, it can only unidirectionally be turned round.Low level vehicle seat and backrest are installed on drive wheel, and preceding slotting lower end links to each other with wheel, and upper end and handlebar are affixed, is convenient to handle.The transmission of drive wheel and flywheel and assembly relation and ordinary bicycle are similar.
