Description
The present invention relates to a kind of electromagnetic booster mechanism that is used for non-power-driven vehicle.
Because Chinese population is numerous, road traffic condition is backward relatively, non-power-driven vehicle, particularly bicycle as the quite general vehicle with long-term existence.In order to solve the unpowered vehicle bigger problem that consumes one's strength, existing many people have carried out the improved trial of unpowered vehicle motorization (for example domestic patent 87 1 02191,86 2 03980,86 2 00885, US Patent 2586,702 etc.).Its mode roughly has the motor drives friction wheel to compress vehicle to drive in addition, electrical motor drive by machine driven system and electrical motor direct drive wheel etc. several.But generally there is following problem in these schemes:
1. complex structure often need change the unpowered vehicle body construction, is unfavorable for transforming on existing vehicle.
2. conversion of electricity-machine and mechanical drive combined efficiency are not high, often cause additional equipment volumes such as storage battery, electrical motor, weight excessive, make the intensity generation problem of unpowered vehicle vehicle frame.If the change car body, the then actual elec. vehicle that becomes is considered to have little significance from the improved angle of unpowered vehicle.
3. driven by power and manpower drive and are not complementary, and most schemes are actual to be with the complete motorization of unpowered vehicle, consider that from the existing transportation condition of China unsuitable large-scale popularization is used.
At above problem, the present invention has designed a kind of non-power-driven vehicle electromagnetic booster mechanism, it does not change original unpowered vehicle structure fully when having use, electricity-machine conversion efficiency height, energy consumption is little, assist system volume, weight are little, and the advantage that does not change the basic ride characteristics such as speed, braking of unpowered vehicle.
Principle of the present invention is described as follows by Fig. 1: the stressing conditions the when permanent magnet of analysis-motion passes through the magnetic air gap that is made of iron-core coil.Fig. 1 a represents that permanent magnet is close to the magnetic field interaction scope along sense of motion, but the situation of its line of centers during as yet not with the core magnetic pole central lines.This moment, the mutual action of magnetic field of permanent magnet and core field was to make the permanent magnet both sides be subjected to the effect of tensile force f respectively along sense of motion according to the direction of current that marks among the figure.Because the cause of symmetry, F is offsetting perpendicular to the component on the sense of motion, and the result is that permanent magnet is subjected to the force action along sense of motion.Fig. 1 b represents that permanent magnet is along forward direction motion to self line of centers and the situation during the core magnetic pole central lines.The effect that this moment, permanent magnet did not stress on sense of motion.This point is in theory as the transformation point of direction of current.After permanent magnet was crossed the line of centers of core magnetic pole along sense of motion, the direction of current in the coil was shown in Fig. 1 c, and magnetic field of permanent magnet and core field mutual action at this moment is to make permanent magnet be subjected to inclination thrust F along sense of motion as can be known in view of the above.Same cause owing to symmetry, F cancels out each other at the component perpendicular to sense of motion, and the result is that permanent magnet is subjected to the force action along sense of motion.In a word, as long as the direction of current in the suitable control coil can make permanent magnet be subjected to application force along sense of motion all the time when passing through the iron circuit air gap.
When being used for non-power-driven vehicle by the boosting mechanism of above-mentioned principle design, as long as iron-core coil is fixed on the vehicle frame, again some permanent magnets circumferentially are fixed on the top of spoke equably along wheel, when making wheel, the permanent magnet on it passes the air gap of iron circuit successively.Suitably the control current direction just can make wheel be subjected to continuous pulsation thrust.
Enforcement of the present invention is example with the bicycle, can be undertaken by following scheme: as shown in Figure 2, the iron-core coil of boosting mechanism [1] is fixed on the cycle frame, and its iron core is changed by the thick silicon steel plate of 0.5mm.The sectional area of iron core is not less than 25 * 25mm.One excitation coil [6] and [7] respectively are housed on the iron core of wheel both sides, and each coil is made of copper cash coiling 1200 circles of Φ 1.0.Permanent magnet [4] is selected nd-fe-b (Ne-Fe-B) Cylinder of Φ 20 * 12 for use, and its mounting means such as Fig. 3 on bicycle spoke shows.The power supply of boosting mechanism [5] is selected the storage battery of 6V 8A/hr for use, and its profile can be considered by dual mode: the first is made the prolate square by bicycle tail-bracket size, is installed on the tail-bracket.It two is to do the growth Cylinder, is installed on the vehicle seat support.The installation site of [2] and [3] two dry-reed tubes in [2] and [3] indication circuit schematic diagram 4 among the figure.The principle of boosting mechanism control circuit is described as follows by Fig. 4: two reed switch relays of [2] and [3] expression among the figure, and hollow triangle is represented open contact, solid triangle is represented normally closed contact.[2], the installation site of [3] two dry-reed tubes should be debugged with the process of following narration and be conformed to: at first, and when permanent magnet does not advance the electromagnetic mechanism air gap and apart from air gap when far away, [2], the open contact of [3] all disconnects, and no current flows through in this moment coil.Along with the rotation of wheel, permanent magnet is close to when beginning to take place interactional position (method of available static debugging is determined) with core field to air gap, the open contact closure of [2], and coil current is connected, and its direction is as shown in Figure 1a.When permanent magnet further moves in air gap, the open contact closure of [3].When the permanent magnet line of centers arrived a certain optimum position (can determine by test) of fast and core magnetic pole central lines, the open contact of [2] disconnected, and the open contact of [3] still remains closed, subsequently the direction of current in the coil such as Fig. 1 b.When permanent magnet travels forward when breaking away from the effective range of core field substantially again, the open contact of [3] disconnects, and coil returns to not powering state.Above process circulation is carried out, and makes wheel be subjected to the effect of thrust continuously.
Foregoing circuit is actual to be a LR circuit, because shortened current"on"time when vehicle wheel rotational speed raise, permanent magnet strengthens by the inverse electromotive force that air gap produces in coil simultaneously, for guaranteeing that the iron-core coil magnetic pole produces enough big magnetic induction density, when bicycle speed improves, require power supply voltage to do corresponding rising.The dial switch of a voltage has been installed on the right handlebar of bicycle for this reason, has been comprised three different voltage gears and a zero voltage gear, in order to adapt to the manual switch that different bicycle speeds and conduct power up and cut off the power supply.Corresponding with dial switch, comprise a pressure regulation part [8] in the control circuit (Fig. 4), it realizes the adjustment of voltage according to the residing gear of dial switch.Divide the selection of retaining voltage levvl, follow following principle: guarantee that promptly under each retaining voltage, bicycle need not apply the manpower driving can be stabilized in a certain common speed when level road travels.During acceleration, need carry out manpower and driven by power simultaneously.For guaranteeing that improved bicycle do not lose the base speed characteristic of unpowered vehicle, the maximum speed of electric power independent drive is adjusted to below the 20km/hr.This moment, the power consumption of whole boosting mechanism was not more than 25w.In addition, added a source switch with bicycle rear brake system interlock between power supply and the control circuit, when bicycle rear was implemented braking, it had good braking ability with the coil automatic cutout of power supply and boosting mechanism to guarantee bicycle.
Because the present invention has taken into full account commercialization when being used for non power driven vehicle and the factors such as restriction of Chinese existing road transportation condition in the design of the theory and structure of mechanism, particularly adopts the strong magnetic force permanent magnet material of neodymium iron boron to improve Electricity and machine conversion efficient. Expectation will have reasonable promotion prospect.
