Description

Voltage-stabilizing rectifier for motorcyle generator

The present invention be a kind of motorcycle that can prolong with the electrical equipment in storage battery useful life, and this electrical equipment is not afraid of short circuit, is opened circuit, overload and superpressure, the life-span can reach alternating current generator stabilized rectifier more than 10,000 hours, can fuel-economizing.

At present, the storage battery that well-known motorcycle uses, the life-span is very short.Compare with the storage battery that automobile uses, automobile can use about 2 years, and motorcycle only uses about half a year and just scrapped.Its main cause is: generator is not installed voltage regulator or pressurizer.Engine changes from the per minute hundreds of and just begins the storage battery charging, arrive several thousand when changeing (voltage reaches as high as 35V) charging current of storage battery has been surpassed several times, make storage battery because of overcharge, active material early fallout and scrapping.Output voltage that if can stable generator just can prolong useful life of storage battery.Therefore, I have developed the utility model stabilized rectifier that this kind rectifier and pressurizer are integrated, and directly replace former rectifier, and the output voltage of stable generator prolongs useful life of storage battery.And the life-span of this rectifier can reach more than 10,000 hours.Both be not afraid of short circuit, and be not afraid of yet and open circuit and transship, also can save fuel consumption.At present the electronic type regulator that occurs is to utilize the method for shorted to earth leakage current to come burning voltage, and generator is the energy of consumption of engine all the time, though also can voltage stabilizing, prolong the life-span of storage battery, be unfavorable for energy-conservation.Therefore, this method is worthless.This rectifier is operated on off state, and when the electric weight of storage battery when sufficient (reaching 7.5V), or motorcycle is not when turning on light electricity consumption, and this rectifier ends, generator idle running, consumed energy hardly.The advantage that therefore, fuel-economizing is arranged.

Though the utility model stabilized rectifier has the contact, can be considered contactless.What adopt because of the contact of this rectifier is very long tongue tube of life-span, and only as the base stage that triggers transistor, operating current has only about 0.25mA.So little electric current is a naturally-aged to almost not infringement of contact.So, can be considered contactless.

The utility model stabilized rectifier can be considered the product of permanent use.Because of the electronic type regulator efferent duct that occurs at present is operated in magnifying state, heating problem is to cause the major reason damaged, and is disposable products.And this rectifier is operated on off state, and is provided with voltage limiter, flow restricter and short-circuit protection, and long-term short circuit and overload can not burnt yet.And form with discrete component, simple in structure, cost is low, does not need very high maintenance technique, and the element that is adopted is at present the most general, uses in case damage also can repair again.So, can be considered the product of permanent use.

The utility model stabilized rectifier can be useful for motorcycle and other vehicle of various use alternating current generators.

The utility model stabilized rectifier also has a function to be: after changing the voltage limiting value of flow restricter, can be used as automatic charger and use.

Below in conjunction with Fig. 1 the rectifier of the utility model stabilized rectifier and the operation principle of pressurizer are summarized as follows:

Rectifier by the D1-D4 rectification after, anodal by flow restricter shunt resistance R5 output, negative pole is by electronic switch BG3 ground connection.

The voltage limiter of pressurizer can be regarded a magnetic voltage stabilizer as, is made up of L1, K1, R1 and R2.Adjust the position of tongue tube K1 in coil L1 or the resistance of resistance R 2, voltage is 7.5V when making output voltage reach setting 7.5V(because of 6V storage battery full charge).Because of L1 is attempted by output, output voltage is higher than setting, will make the K1 closure, triggers electronic switch, cuts off output current.Therefore, no matter how high generator voltage is, output voltage is stabilized on the magnitude of voltage of regulation all the time by solenoid L1 clamper, and storage battery is not had the overcharge phenomenon.

The flow restricter operation principle and the voltage limiter of pressurizer are basic identical.Form by L2, K2, R5, D5 and C.Because of solenoid L2 by D5 be connected in the output circuit after R5 is in parallel, output current surpasses limit value will make the K2 closure, triggers electronic switch, cuts off output current.Adjust the position of tongue tube K2 in coil L2, output current is limited in the 6A.Its total electricity consumption electric current can reach 6A(such as the need output current can strengthen the resistance of R5 when 3A is following when turning on light because of night running, otherwise reduces its resistance).Because of output is pulsating current, thereby make L2 obtain smooth direct current and stable work with C filtering.D5 prevents the external electrical equipment discharge of C.

The short-circuit protector of pressurizer is to be realized by the operating characteristic of BG1, and what adopt because of BG1 is the positive-negative-positive pipe, and the output short circuit just equals emitter and the base stage short circuit of BG1, and BG1 is ended, and electronic switch cuts out, the cut-out output current.

The temperature compensation means of pressurizer is to keep voltage limiting value with the method for voltage limiter coil L1 series thermal-sensitive resistance R 1, and when temperature raise, the L1 resistance can increase, but the R1 resistance can reduce, thereby it is constant to flow through the electric current of L1, and output voltage is remained unchanged.
