The device has the advantages that the device can smoothly start the automobile engines at one time particularly for diesel engine road vehicles in winter, does not affect the normal power supply of the automobiles, has simple assembly and convenient use, and is safe and reliable.

Description

The emergency starting device of motor car engine

Technical field

The invention belongs to the starting arrangement field of motor car engine, relate to the emergency starting device of motor car engine.

Background technique

In the winter time, because temperature is low, car is cool, especially the motor of diesel-oil vehicle; Often be difficult to starting, the starting even that has for this reason, is not often adopted some simple approach; Like trailer, feed tank adds hot water, or improves fuel oil temperature; Individual other also has with the fire baking, and be not only very inconvenient, and obviously have unsafe factor.

Summary of the invention

The technical problem that solves:

A kind of emergency starting device of motor car engine is provided, and storage battery is together interrelated through throw over switch, and the starting voltage of the starter motor through improving motor car engine realizes the emergency start motor car engine; Can overcome the deficiency that exists in the existing technology, both just in the winter of severe cold, particularly for diesel-oil vehicle, also one push start motor car engine smoothly is equipped simple, easy to use, safe and reliable.

The technological scheme that adopts:

The emergency starting device of motor car engine; Comprise storage battery; Starter motor and ignition switch is characterized in that: also be useful on the throw over switch of operation of regulation and control normal starting and emergency start, storage battery is connected in the power supply circuits through the interrelated formula of throw over switch; Under the control of throw over switch, needed emergency start voltage can be provided for the emergency start of motor car engine; The power supply circuit construction of said emergency starting device has two kinds; A kind of is when the emergency start motor; Under the emergency start voltage status when power supply voltage of power supply system all is in the emergency start motor in the car; Perhaps be another kind of, when the emergency start motor, under the emergency start voltage status when having only the starting voltage of the starter motor of motor car engine to be in the emergency start motor.

Beneficial effect:

The emergency starting device of motor car engine, starting voltage---the emergency start voltage of the starter motor through improving motor car engine is realized the emergency start motor car engine; In the winter time, particularly for diesel-oil vehicle, one push start motor car engine smoothly, get final product the longest 3～5 seconds, and do not influence the automobile normal power supply, equipped simple, easy to use, safe and reliable.

Description of drawings

When Fig. 1, emergency start motor, power supply system all is in the power supply circuit construction figure of emergency start voltage status in the car;

When Fig. 2, emergency start motor, have only the voltage of the starter motor of motor car engine to be in the power supply circuit construction figure of emergency start voltage status;

Embodiment

In conjunction with further explanation in detail of accompanying drawing;

is shown the ground connection of forging iron among the figure;

As shown in Figure 1, the first throw over switch K among the figure ₁State when being in the emergency start motor, the first throw over switch K ₁Be the double-pole dibit pattern, two of the m of a cutter, n respectively with g, the f two bit synchronization displacements of b cutter; The positive and negative electrode of first storage battery 1 connects a, b cutter respectively, and positive pole connects electrical apparatus for vehicle use 5 simultaneously, and connects starter motor 4 through ignition switch 3; The positive pole of second storage battery 2 connects the m position of a cutter and the f position of b cutter simultaneously, when negative pole connects the g position of b cutter, connects power supply in the car, or the ground connection of forging iron, and the n position of a cutter is the room; The voltage of two storage batterys should equate that two storage batterys are series connection during the emergency start motor, and two storage batterys are parallel connection when reaching operation after the engine start; This kind circuit structure is particularly useful for carburetor type and supplies fuel oil to motor, and especially normal power supply voltage is the vehicle of 12V.

As shown in Figure 2, the second throw over switch K among the figure ₂State when being in the emergency start motor, the second throw over switch K ₂Be three cutter dibit patterns, the c cutter 1., 4. two respectively simultaneously with the d cutter 2., 5. two, the e cutter 3., 6. two bit synchronization displacements; The positive pole of the 3rd storage battery 6 connects the 6. position of e cutter, connects starter motor 4 through ignition switch 3 simultaneously, and negative pole connects the 3. position of positive pole, d cutter and the e cutter of the 4th storage battery 7 simultaneously; The negative pole of the 4th storage battery 7 connects the c cutter; The positive pole of the 5th storage battery 8 connects the 1. position of c cutter and the 5. position of d cutter simultaneously, when negative pole connects the 4. position of c cutter, connects power supply in the car, or the ground connection of forging iron; The e cutter connects electrical apparatus for vehicle use 5, and the 2. position of d cutter is the room; The 4th storage battery 7 should equate with the voltage of the 5th storage battery 8, and three storage batterys are series connection during the emergency start motor, be the 4th storage battery 7 after the engine start and during operation with 8 parallel connections of the 5th storage battery after connect with the 3rd storage battery 6 again; This kind circuit structure is particularly useful for electric-jet type and supplies fuel oil to motor, and especially power supply voltage is the vehicle of 24V.

The dibit function of throw over switch does, an emergent position required when being the emergency start motor, and the normal bit when be normal starting motor and operation should in time transfer normal bit to afterwards with an emergent position emergency start motor.

Because mostly automobile storage battery is the multiple of 12V, except that should satisfying emergency start voltage and automobile normal power supply voltage needs, also should satisfy power requirements during the storage battery coupling.

Generally speaking, during the emergency start motor car engine, the emergency start voltage of supplying with starter motor is 1.5～2.0 times of normal starting voltage, should guarantee to realize emergency start, again can not be in response to the too high and infringement starter motor of anxious starting resistor.
