Abstract

A parking and retrieving assisting mechanism for miniature walking-substituting vehicle relates to an assisting mechanism which passes by a slope when the vehicles such as bicycle, electric vehicle and motorcycle are parked and retrieved from a basement. The mechanism can effectively prevent the following problems in descending of the vehicle: severe damage of tire and greatly shortened service life of the vehicle because of the sliding friction of the tire on the slope because of braking. Simultaneously a problem of high difficulty in pushing when the vehicle ascends is effectively settled. According to the mechanism, a resistance which is normally performed manually for preventing quick movement of the vehicle is converted to gravitational potential energy of a counterweight when the vehicle descends in the slope. The counterweight is pulled from a lower dead point to an upper dead point. Furthermore a blocking device is used for keeping the counterweight at the upper dead point for storing the energy so as to transferring the gravitational potential energy to the vehicle when the vehicle ascends on the slope, thereby obtaining an effect of labor saving and high speed in ascending on the slope.

According to force analysis and practical operation experience, walking-replacing tool is when entering basement, must check the trailing wheel brake, rely on trailing wheel and the sliding friction on inclined-plane and the people comes balancing vehicle to vehicle pulling force backward descending acceleration, tire sliding friction on the ground acutely increases the Tyte Wear degree, has shortened the application life of tire greatly.Equally, when walking-replacing tool outwards took out from basement, for the heavier car of vehicle itself, it very was hard that a people's of dependence strength is shifted vehicle onto ground, and the thrust size must just can make vehicle pass through the slope greater than power F=sina*G.

Summary of the invention

Must tight brake when overcoming run in the car stowage process descending, the heavy wear tire.Be difficult to the reality that promotes when up again.The utility model provides the servicing unit in a kind of up-downgoing process, in the time of can effectively avoiding vehicle descending, cause tire impaired because of brake causes the sliding friction of tire on the inclined-plane, influence the application life of tire, also efficiently solve simultaneously the problem that vehicle is difficult to promote when up.

The technical scheme of this utility model is made up of assembly pulley, wire rope, balancing weight, slide block, track, handwheel devices, buffer spring, blocking mechanism etc.

This mechanism utilizes vehicle on the inclined-plane when descending, for preventing the downward fast moving of vehicle, originally the resistance institute work that relies on the people to apply is converted into the gravitional force of balance weight, balance weight from moving to point down to point, and is utilized retention device, balancing weight is remained on to putting the position, energy is stored, so that vehicle when up, is transferred to vehicle to gravitional force on the inclined-plane, thereby when going up a slope, reach the effect of light and fast.

This utility model has mainly utilized acting to equate, energy transforms, movable pulley labour-saving principle, and the difference factor of considering type of vehicle weight weight, balancing weight is designed to body structure, there is the movable little balancing weight of polylith to fill in the casing, the weight of casing can be regulated voluntarily according to the weight of vehicle and the gradient on inclined-plane thereof like this, make casing heavily approximate vehicle weight, because the weight at pulley two ends about equally, both sides are under the equilibrium state, no matter descending or up can being similar to regards mobile on horizontal plane as to vehicle, thereby do not need brake, only need slight strength just can control advancing of car.

The beneficial effect of this utility model is: this mechanism is pure machine driving, does not have electric elements, does not need electric energy, is saves energy like this, has responded country's " energy-saving and emission-reduction " policy and has called, and simultaneously simple in structure, equipment cost is lower, can be by wide popularization and application.
