Abstract

The utility model relates to a pneumatic aid device of non-power vehicle. In the condition that the energy source is not consumed, in order to solve the problem that riding bicycle on an upgrade or loading heavy objects is laborious, the utility model discloses an aid device which is mainly composed of a crank link mechanism and an air reservoir. The utility model is characterized in that a cylinder body is communicated with the air reservoir through an air outlet pipe and an air inlet pipe. While in use, the utility model is matched with a bicycle wheel shaft of the non-motor vehicle. In riding on a downgrade, the energy is stored in a high pressure air mode. In riding on the upgrade, a piston is pushed by the high pressure air to do reciprocating movement to play the aid action. The utility model has the advantages of energy saving, labor saving and no pollution, and is suitable for being popularized and used in mountain areas, mining areas and cities with uneven terrain.

Description

Unpowered vehicle air assisted device

The utility model relates to a kind of unpowered vehicle air assisted device, specifically a kind of that mainly constitute by cylinder block crankshaft case group, piston rod group and crank teeth wheels, be used on the unpowered vehicle to reach laborsaving destination device.Bicycle has the low health of simple in structure, cost, use with it and advantage such as easy to maintenance is extensively adopted by the people of country variant, different regions, different road conditions.Along with the progress of society and the quickening of rhythm of life, people are also more and more higher to the various performance demands of bicycle.Therefore, various labour-saving bicycles arise at the historic moment thereupon.This wherein so that the most obvious with the morpet labor-saving effect of electric energy, oil plant, but still there are some shortcomings in this class bicycle, such as: because of its consumes energy, often use daily expenditure big; Have waste gas to discharge, environmental pollution is serious etc.

The purpose of this utility model provides a kind of unpowered vehicle air assisted device that does not need consumed power, oil plant.It is not only laborsaving that this device is installed on unpowered vehicle, and because of consumes energy not need not to increase daily expenditure, also do not have the waste gas discharge, very useful to preventing the pollution of the environment.

The purpose of this utility model is achieved in that by fixing two cylinder blocks or multiple-cylinder body crankcase group, the main body that the piston rod group of motion and crank teeth wheels constitute this work-saving device, wherein, the osed top cylinder head is arranged at the top of cylinder block, the middle and lower part of sidewall is provided with vent, the piston that is positioned at cylinder block links to each other with same bent axle by connecting rod respectively, end at bent axle is fixed with gear, it is characterized in that: link being provided with on the cylinder head between thimble and with the unidirectional freeing pipe that has master cock, cylinder block links by a unidirectional air inlet pipe and an air receiver that is provided with on the gentle cylinder wall of this unidirectional freeing pipe respectively.

During use, air receiver part, cylinder block partly can be separately fixed at crossbeam, cant beam or the wheel face of bicycle, master cocies etc. are installed near the handlebar, and by transmission devices such as gear, chain, engaging and disengaging gear or tooth axle groups crankshaft toothed gear are matched with the axletree of bicycle.Its working process mainly is divided into inflation and power-assisted two parts.When bicycle descending or zero load, close the master cock on the unidirectional freeing pipe, make crankshaft toothed gear along with axletree together rotates by the operation engaging and disengaging gear again, and drive piston through bent axle, connecting rod and pump, with piston motion during to bottom dead point from the vent suction air, clamp-on air receiver by unidirectional air inlet pipe when the piston stroking upward, so repeatedly, finish the inflation task of air receiver.When bicycle upward slope or loads need power-assisted, open the master cock on the unidirectional freeing pipe, high pressure gas in the air receiver has pushed in the thimble valve fill gas cylinder body during because of the piston arrives top dead point, promote descent of piston and have portion gas to discharge from vent, meanwhile, last piston a descending piston stroking upward after bent axle drives, and the residual air in the cylinder block clamp-oned air receiver by unidirectional air inlet pipe, when back one piston is pushed to top dead point, having pushed the thimble valve begins descending again, crankshaft toothed gear is ceaselessly rotated, and this power is applied on the axletree, finished the power-assisted task by transmission device.

The utility model has the advantages that: do not changing substantially on the basis of bicycle original design, install this air assisted device additional, under the situation that does not consume extra powers such as any electric energy, oil plant, with the bicycle descending or when unloaded unnecessary energy store with the form of high pressure gas, as going up a slope or power resources during loads.Not only do not increase rider's daily expenditure, and do not have problem of environmental pollution because of there not being waste gas to get rid of.As seen.This work-saving device has not only solved the problem that it is difficult to go up a slope by bike in mountain area, mining area, and is of value to the city large-scale popularization of physical features injustice.Can also on air receiver, establish an air-filled pore, behind air-pump inflating as the usefulness of travelling, going out, going up a hill etc.In addition, use this device, can give air receiver Tyre inflating as emergent usefulness as tracheae.Certainly, this driving engine also is applicable to other all unpowered vehicles such as three-wheel vehicle.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is one of the present utility model and uses the embodiment scheme drawing.

The utility model is described in further detail below in conjunction with accompanying drawing:

As shown in Figure 1: this air assisted device mainly is made of fixing two cylinder block crankshaft case groups, the piston rod group and the crank teeth wheels of motion.Wherein, the top of cylinder block (3) has vent (4) on osed top cylinder head (2), the sidewall, and the piston (8) that is positioned at cylinder block (3) links to each other with same bent axle (6) by connecting pavilion (7) respectively, is fixed with crankshaft toothed gear (5) at an end of bent axle.Be provided with thimble valve (1) and link with the unidirectional freeing pipe (11) that has master cock on cylinder head (2), cylinder block (3) links with an air receiver (10) by the unidirectional air inlet pipe (9) that is provided with on this unidirectional freeing pipe (11) and the cylinder body wall respectively.

As shown in Figure 2: during use air receiver (10), cylinder block (3) are separately fixed on crossbeam and the cant beam, master cock is installed on the handlebar, and the gear cluster transmission devices such as (13) by chain, gear, band engaging and disengaging gear makes crankshaft toothed gear (5) match with axletree (12).By the switch of operation sheet on freeing pipe, select gas replenishment process or power-assisted process.Also can select use this work-saving device or need not by the operation engaging and disengaging gear.

On air receiver, can be provided with limiting valve or air-pressure gauge.Be provided with on the air receiver limiting valve or air-pressure gauge can when the tube internal gas pressure reaches certain limit, discharge automatically or the cyclist is found after in time stop gas replenishment process.

In addition, this air assisted device also can adopt the multiple-cylinder body except that adopting two cylinder blocks; Structurally remove and adopt single-column type, can also adopt other modes such as opposed type, V-type to adapt to the needs of different unpowered vehicle different capacities, different fixing position.
