Description
Technical field
It the utility model is related to a kind of vacuum control unit for braking system of electric car.
Background technology
Pure electric automobile has become the new-energy automobile being most expected after internal-combustion engines vehicle, each government and
The major Automobile Enterprises in the whole world are numerous and confused all using electric car as following developing direction, in next a century of new century, as gathering around
The China for having the maximum automobile market in the whole world seems to make an exception, and either government, or business circles, electric car has become most
Popular topic.
Most of car uses vacuum servo servo brake system more, is used in combination using manpower and power.Tradition
The vacuum source of the brakes vacuum booster unit of internal combustion engine car comes from engine suction manifold, and vacuum negative pressure can reach
0.05-0.07Mpa.For the pure electric vehicle repacked into by traditional vehicle, after engine assembly is removed, only as produced by manpower
Brake force can not meet the needs of travelling brake, it is therefore desirable to brakes vacuum booster unit is changed a social system, and changed a social system
Key problem be to produce the vacuum source of enough pressure.
And orthodox car is equipped with vacuum booster unit, its vacuum source comes from engine air throttle rear or engine driving
Vavuum pump.Electric automobile does not have the engine of orthodox car, and vacuum source must come from electric vacuum pump.
Utility model content
The purpose of the utility model is to provide a kind of to be used for braking system of electric car the defects of for prior art presence
Vacuum control unit.
The utility model to achieve the above object, adopts the following technical scheme that：It is a kind of for braking system of electric car
Vacuum control unit, including ignition switch, the output end of the ignition switch are connected with full-vehicle control unit, the full-vehicle control
Unit and vacuum control unit two-way communication link, the signal input part of the vacuum control unit is with being arranged in vacuum tank
Pressure sensor is connected, and the signal output part of the vacuum control unit is connected with electric vacuum pump, the electric vacuum pump
Output end is connected by the first check valve with the vacuum tank, and the output end of the vacuum tank is helped by the second check valve with vacuum
Power device connects.
The beneficial effects of the utility model：Vacuum control unit in the utility model can be carried out to the vacuum of vacuum tank
Complete monitoring, when the vacuum of vacuum tank is less than a certain value, meeting automatic start Motorized vacuum pump work, sets when vacuum reaches
Motorized vacuum pump work can be automatically stopped during definite value again, it is ensured that the vacuum of vacuum tank is always in safety standard value scope.And set
The first check valve, the second check valve put can control the one-way flow of vacuum, cause to leak to prevent vacuum reverse flow.
Brief description of the drawings
Fig. 1 principle of work and power schematic diagrames of the present utility model.
Embodiment
Shown in Fig. 1, it is related to a kind of vacuum control unit for braking system of electric car, including ignition switch, it is described
The output end of ignition switch is connected with full-vehicle control unit, and the full-vehicle control unit connects with vacuum control unit two-way communication
Connect, the signal input part of the vacuum control unit is connected with the pressure sensor 2 being arranged in vacuum tank, the vacuum control
The signal output part of unit is connected with electric vacuum pump, the output end of the electric vacuum pump by the first check valve 1 with it is described
Vacuum tank is connected, and the output end of the vacuum tank is connected by the second check valve 3 with vacuum booster.
In this utility model, the vacuum control unit of setting can carry out complete monitoring to the vacuum of vacuum tank, take seriously
Meeting automatic start Motorized vacuum pump work when the vacuum of slack tank is less than a certain value, again can be automatic when vacuum reaches setting value
Stop Motorized vacuum pump work, to ensure that the vacuum of vacuum tank is always in safety standard value scope.And first set is unidirectional
Valve, the second check valve can control the one-way flow of vacuum, cause to leak to prevent vacuum reverse flow.
During work, when ignition switch closes, full-vehicle control unit controls vacuum control unit to work first, vacuum control list
Member receives the vacuum signal of pressure sensor offer；As vacuum reaches automotive safety criterion of train running, vacuum control unit
Feeding back to full-vehicle control unit can be with normally travel signal, and full-vehicle control unit control automobile can be with normally travel；Such as vacuum
Also be not up to automotive safety criterion of train running, vacuum control unit do not feed back to full-vehicle control unit can with normally travel signal,
Automobile cannot normally travel.Meanwhile vacuum control unit control Motorized vacuum pump work, until vacuum tank vacuum reaches vapour
Car safe driving standard, automobile just can be with normally travels.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
