Abstract

The utility model discloses a non blind area manpower force applying device, in particular to a power supplying device for the manpower pedaling transport vehicles. The utility model consists of pedals, locating bracket, the oriented wheels mechanism. Wherein, the pedals and the pedal swivels are connected, and the pedal swivels are also connected with the pedal rod which is connected with the oriented wheels mechanism. The pedals rotates in the way that the oriented wheels mechanism is treated as the center and the pedal rod as radius, and besides, the locating bracket is arranged on the main pole, which is in shape of double curve. The upper curved end is connected with the main pole, and the locating pole makes the upper and the lower bent ends meet the rotating path made by the pedal rod. Therefore, the upper and the lower bent ends of the locating rod is able to restrict the pedal rods and rotate around the ground vertical line. The rotating range is less than 90 degrees so that the pedals stay close to the front part of the vehicle or the rear part, in which way the vehicle driver is able to pedal up and down to keep off the force applying blind zone.

Description

Non-blind area manpower force application apparatus

Technical field

The utility model relates to a kind of manpower force application apparatus, refers in particular to a kind of device that power is provided for the manpower override type vehicle.

Background technology

Present bicycle and man, three-wheel vehicle etc., because its economy, still be widely used in people's various fields in life, but the force application apparatus of this override type tradition car, always be to prolong and use by of the design of two application of force pedals with the symmetrical captive joint of 180 degree, finishing by pushes pedals rotation provides power, because when its pedal turns to when becoming vertical angle with ground, can there be application of force blind spot and can't the application of force, traditional terms of settlement is to rotate voluntarily by inertia to overcome the blind spot application of force, if go up when breaking but meet row, because the speed of a motor vehicle is slower, then can not overcome the blind spot application of force by inertia, the personnel's of travelling go-cart of must getting off is so brought inconvenience very to driving.

The utility model content

In view of the above shortcoming of prior art, the purpose of this utility model is:

A kind of needs pushes pedals up and down reciprocatingly is provided, just can realizes the device of the application of force, this force application apparatus does not have blind spot application of force district, no matter is that level land or last breaking can both make things convenient for the cyclist to drive.

The technical scheme that its technical matters that solves the utility model adopts is:

A kind of non-blind area manpower force application apparatus is provided, and it mainly is made of pedal, locating rack, directional wheel mechanism;

Its pedal is connected with the pedal rotary head, and the pedal rotary head is connected with pedal-rod, and pedal-rod is connected with directional wheel mechanism, and directional wheel mechanism is connected with large fluted disc, large fluted disc and chain engages; Directional wheel mechanism is meant the mechanical mechanism that can realize to a direction rotation of appointment here, and pedal can serve as to change the heart with directional wheel mechanism, is that radius rotates with the pedal-rod;

Its locating rack is arranged on the big hack lever, locating rack be one " [" two bendings, last bending end is connected with big hack lever, the length of locating rack, position just in time make the upper and lower bending end of locating rack, and be crossing with the rotary motion trace of pedal-rod; Like this, it always is one side rotation at center with the ground perpendicular line that the upper and lower bending end of locating rack just can limit pedal-rod, this pivot region is less than 90 degree, so make the position of its pedal or maintenance relies on headstock or relies on the tailstock, navigating mate is pushes pedals up and down reciprocatingly just in use.

Above-mentioned directional wheel mechanism is made of pedal shaft, pedal shaft cover, miniature gears, directed pin, directional head, large fluted disc cover, large fluted disc; Pedal shaft is provided with fixing miniature gears, and the pedal shaft cover is placed in pedal shaft, and pedal shaft and pedal shaft cover can rotate, and the pedal shaft cover is captiveed joint with big hack lever, realizes integrating with vehicle body; Large fluted disc is captiveed joint with the large fluted disc cover, and the large fluted disc cover also also can rotate with the pedal shaft socket; Large fluted disc is provided with directed pin and directional head, and directed pin can rotate with the center-point of self, and its directional head is at an end position of directed pin, and limiting its directed pin can only rotate in a counter-clockwise direction, and directed pin can block miniature gears simultaneously.When downward pushes pedals, pedal shaft will rotate counterclockwise and drive pinion rotation, drive directed pin simultaneously and clockwise rotate, can be directed head when directed pin clockwise rotates and block, rotate counterclockwise engagement chain drive car and travel so can drive large fluted disc; When upwards regaining pedal, pedal shaft will clockwise rotate the drive pinion rotation, drives directed pin simultaneously and clockwise rotates, and this moment, directional head can not block directed pin, and at this moment, large fluted disc then can not be reversed the application of force and the car backward takes place.

Above-mentioned pedal can also be provided with pedal hook, and the front end that pedal hook is arranged at pedal can be a collar shape, and the tiptoe of navigating mate can be put in the pedal hook, when reciprocal pushes pedals, can pedal upwards be taken back by tangling pedal hook then.

Above-mentioned pedal-rod can also be provided with spring, one end of spring is connected with pedal-rod, the other end is connected with big hack lever or locating rack, and the elastic force by spring just in time keeps its pedal to touch mutually with the last bending end of locating rack automatically all the time, and spring also can be realized the pedal withdrawal that makes progress automatically.

The beneficial effects of the utility model are:

Because locating rack can limit pedal-rod and always rotate on the one side that with the ground perpendicular line is the center, this pivot region is less than 90 degree, so the position of pedal or maintenance rely on headstock or rely on the tailstock, can not only make things convenient for navigating mate pushes pedals up and down reciprocatingly, make it not have blind spot application of force district, and since locating rack can limit pedal-rod and can not rotate ground-surface perpendicular line, can also guarantee when last breaking, car more can be not too late because of the application of force, by locating rack pedal-rod is blocked, and big voluntarily distance falls back.
