Description
Technical field
The utility model relates to passenger car field more particularly to vehicle electricity systems.
Background technique
Electricity consumed by electrical apparatus for vehicle use carrys out self generator, and voltage rating is in 14V and 28V or so, in order to by voltage control
System must use voltage regulator within this range.Voltage regulator is generally divided into single function voltage regulator (thick film patch
Circuit), multifunctional electric adjuster (integrated IC), Intelligent voltage regulator.These voltage regulators are all that basis constantly detects
To voltage levels carry out on-off energized circuit.
Generator is mainly made of field frame assembly, rotor assembly, rectifier bridge, voltage regulator, a front and rear cover, end cap
Body is that automobile circuit cathode is directly connected on vehicle frame or is connected to battery terminal negative by end cover body conductor introduction, from rectifier bridge
Upper extraction anode is connected to battery positive voltage.
With the intelligentized development of vehicle, it is also complex that electrical appliance constantly increases electricity system, from being assembled to visitor
This process running in stage electricity system is also easy to produce high pressure and high energy impact events phenomenon in the hand of family, and generator is as main power source
And be to be chronically at operation state, so easily damage generator and voltage regulator, once damage vehicle lacks power supply
It can not just travel.
The present passenger car in China and commercial ownership hand over height, but car owner not quite understands vehicle mounted electrical apparatus, is easy to produce mistake
Operation also results in and generates high pressure and high energy impact events phenomenon in electricity system.
Utility model content
Technical problem to be solved in the utility model is to realize a kind of operation more reliable vehicle electricity consumption of safety and stability
System.
To achieve the goals above, the technical solution adopted in the utility model are as follows: vehicle electricity system, vehicle battery are defeated
Outlet connection load, the end GND of system connect vehicle battery output end, and the end B+ of multifunctional electric adjuster is linked into described
Between the end GND and accumulator output end, access has circuit between the end B+ of the multifunctional electric adjuster and the end GND
Protect device.
The circuit brake is super bulky capacitor.
The circuit brake is TVS pipe.
The end B+ of TVS pipe one end connection multifunctional electric adjuster, the other end are grounded by current-limiting resistance.
The end GND is in series with capacitor.
Vehicle ECU is equipped with current sampling circuit, and the collection terminal of the current sampling circuit is connected to the TVS pipe and limit
Between leakage resistance.
The vehicle ECU is equipped with test circuit, and the input terminal and output end of the test circuit are separately connected TVS pipe
Both ends, the vehicle ECU export alarm signal to instrument desk for lighting preset alarm lamp.
The utility model has the advantage of inside vehicle electricity system when there is high pressure and high-energy or use process
When middle appearance improperly operates generation high pressure and high-energy, TVS pipe can fall these energy absorptions, improve product and use the longevity
Life, if compared to the prior art the anti-energy impact service life improves 1 times or more (comparative test verifying under severe use environment
Report and after sale failure rate), using the automobile of the system, even if car owner's maloperation, generator will not be damaged and voltage is adjusted
Device and cause vehicle that can not travel.
Detailed description of the invention
The content of width attached drawing every in the utility model specification expression is briefly described below:
Fig. 1 is the utility model vehicle electricity system schematic diagram；
Fig. 2 is background technique vehicle electricity system schematic diagram.
Specific embodiment
As shown in Figure 1, system the end GND connect vehicle battery output end, the B+ of multifunctional electric adjuster terminate into
To between the end GND and accumulator output end, access has circuit between the end B+ and the end GND of above-mentioned multifunctional electric adjuster
Protect device, i.e. between B+ and GND increase a circuit brake, circuit brake preferably to or unidirectional TVS pipe, can also
To use super bulky capacitor, occur improperly when there is high pressure and high-energy inside the vehicle electricity system or in use process
When operation generates high pressure and high-energy, circuit brake can fall these energy absorptions.
For the reliability for ensuring circuit brake work, TVS pipe one end connects the end B+ of multifunctional electric adjuster,
The other end is grounded by current-limiting resistance, and the end GND is in series with capacitor.
Since circuit brake is similar to fuse, belong to consumptive material, if occurring damaging and finding not in time, system can be made
Failure risk increases, and user does not have self-test capability usually, then can be equipped with current sampling circuit in vehicle ECU, electric current is adopted
The collection terminal of sample circuit is connected between TVS pipe and current-limiting resistance, and current sampling circuit both can be with supervisory electronic circuit protection device
It is no to be impacted, vehicle ECU record can also be allowed by the number impacted.
In addition, vehicle ECU is equipped with test circuit, the input terminal and output end of testing circuit are separately connected the both ends of TVS pipe
A circuit is constituted, if breaking down (circuit brake damage), circuit can be breaking, principle detection circuit in this way
Whether protection device is damaged, and allows vehicle ECU to export alarm signal to instrument desk after circuit brake is impaired, is used for point
Bright preset alarm lamp.
Based on the alarm method of vehicle electricity system, self-test after can starting every time can also be every in circuit brake
A self-test is carried out after Secondary Shocks, comprising:
After vehicle powers on, vehicle ECU control test circuit issues electric signal by output end, if input terminal received signal
Value in setting vehicle interval value, does not then export alarm signal to instrument desk, lights preset alarm lamp, normally then alarm；
When current sampling circuit gets dash current, vehicle ECU control test circuit issues electric signal by output end,
If input terminal received signal value in setting vehicle interval value, does not export alarm signal to instrument desk, lights preset report
Warning lamp is normally then alarmed.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, as long as the various unsubstantialities carried out using the method concept and technical solution of the utility model change
Into, or it is not improved the conception and technical scheme of the utility model are directly applied into other occasions, in the utility model
Protection scope within.
