Description
Technical field
The utility model relates to the integral structure of a kind of electromagnetic switch for the start-stop motor and ICR relay and uses the start-stop motor of this integral structure.
Background technology
The start-stop motor also claims the start and stop motor, is used for the engine of start-uping a car.Existing conventional start-stop motor is comprised of motor and electromagnetic switch, and the contact of electromagnetic switch is serially connected with on the major loop of motor, be used for the control motor, dead electricity, be connected with starter toothed wheel on the output shaft of motor.When ignition switch was connected, the contact that the coil of electromagnetic switch gets electric adhesive electromagnetic switch was connected motor main circuit, and motor gets electric operation, and the suction-combining force of electromagnetic switch promotes the gear ring engagement of starter toothed wheel and engine on the other hand, thereby drives engine rotation.
Along with society is more and more higher to the requirement of energy-saving and environmental protection, and the phenomenon of urban traffic blocking increases the weight of, running car is in crowded urban traffic road the time, total unavoidable parking waits traffic lights or the traffic congestion wait, and the energy of engine idle consumption is a kind of waste, but also can increase exhaust emissions amount, contaminated air.Therefore, in recent years fast development goes out a kind of automobile environment-protection technology---engine start stop system, the urban traffic situation that is specially adapted to loiter.When the driver when running into red light or traffic congestion, after braking was stopped vehicle, automobile can be automatically with engine misses, saved idle running and the fuel oil wasted; When again travelling, the engine that resets automatically again, the loss of fuel oil in the time of can reducing engine idle to greatest extent like this has great significance to saving the energy and reduced exhaust.But this requirement to the start-stop motor of automobile improves thereupon, and the start-stop motor need to adapt to frequently or start request fast.Otherwise, can be easy to cause the start-stop motor on the one hand because the starting peak current is excessive, cause shorten its useful life; On the other hand, excessive starting peak current also can impact and damage vehicle electronic device.
In order effectively to reduce the startup peak current of start-stop motor, a kind of start-stop motor that can be applicable to the engine start stop system is provided, the applicant in first to file a kind of " method, relay and the start-stop motor that suppress start-stop motor peak value starting current ", the application number of this utility model application is 201210590649.4, cut-in relay in the loop of start-stop motor, in order to cut and to cut out current-limiting resistance, reach the purpose (referring to Fig. 1,2) that under the prerequisite that does not affect the normal operation of start-stop motor, suppresses the peak value starting current.
But above-mentioned scheme in first to file still has the following disadvantages:
The first, because electromagnetic switch K2 and ICR relay K 1 take larger space all with motor 25 splits and be installed in side by side in the automobile engine installation place, be unfavorable for the miniaturization of automobile engine and the operation of installation, maintenance;
Second, because electromagnetic switch K2 and ICR relay K 1 are single Split type structure separately, need to adopt connecting line to be electrically connected between electromagnetic switch K2 and the ICR relay K 1, this connecting line also must be used wrapped with insulation simultaneously, increase the risk that connecting line and automobile engine are short-circuited, also be unfavorable for the work simplification of start-stop motor;
The 3rd, because the spacing distance of electromagnetic switch K2 and ICR relay K 1 is closer, their installation often needs special fixture, be unfavorable for the simplification of actuating motor mounting process, cause elongated, process costs of its process time to increase, in addition because the installation site of start-stop motor on some vehicle be very narrow, respectively separately to electromagnetic switch K2 and ICR relay K 1 install, the maintenance difficulty of connecting line replacing is very big;
The 4th, because the Split type structure of electromagnetic switch K2 and ICR relay K 1 has reduced to a certain extent the device of electromagnetic switch K2 and ICR relay K 1, the utilance of material, thereby has caused the production cost of start-stop motor also higher.
