Description

A kind of electronic type vacuum pressure controller

Technical field

The utility model is related to controller field more particularly to a kind of electronic type vacuum pressure controllers.

Background technology

Most cars all use vacuum boosting braking system, traditional combustion engine brake system of car vacuum booster unit Vacuum source all derive from motor intake manifold, and pure electric automobile or electric vehicle with pure electric vehicle operating mode be not due to sending out The vacuum power source of motivation inlet manifold depends merely on the demand that brake force caused by manpower cannot be satisfied vehicle braking, therefore must Manpower must be assisted to carry out vehicle braking with electric vacuum booster device.Vacuum pressure controller is by incuding in power-assisted gas tank The pressure changing in portion, the start and stop of control brake vacuum pump, achievees the purpose that vacuum servo.

There are two types of pressure controller products above existing market：One, mechanical type pressing force controller, control accuracy is not high, warp Often there is a situation where drifts, influence the operating point of vacuum pump, lead to vacuum degree deficiency or excessive situation.Two, electronic controller, Often carrying load ability is insufficient, is easy to burn out, be damaged or do not work after being interfered by foreign impacts, and automobile in igniting and In operational process, it is easy to generate Unloading Voltage or even double throwings or situations such as throwing more, electronic controller is made to fail.

Utility model content

In view of the deficiencies in the prior art, the purpose of this utility model is to provide a kind of electronic type vacuum pressure controls Device processed, the case where being highly resistant to circuit throw load, stable, service life is long.

To achieve the above objectives, the technical scheme adopted by the utility model is that：

A kind of electronic type vacuum pressure controller, including control module, the control module include signal processing circuit, The control module is connected with output module, DC/DC voltage transformation modules and pressure acquisition circuit module, the DC/DC voltages Conversion module includes anti-throw load protection circuit module.

Preferably, the pressure acquisition circuit module includes anti-throw load protection circuit module.

Preferably, the electronic type vacuum pressure controller is made using semiconductor chip.

Preferably, the output module includes relay control module and alarm output module.

Electronic type vacuum pressure controller in the utility model, pressure acquisition circuit module connects vacuum pump, main negative Acquisition to vacuum pump air pressure inside is blamed, the variation of absolute pressure is exported, and transmits signal to control module, in control module The information of input is identified in signal processing module, and transmits signal to output module；DC/DC voltage transformation modules be responsible for by Vehicle-mounted 12V power units are converted to the power supply supply pressure acquisition circuit module of 5V stabilizations and control module uses, wherein anti- Throw load protection circuit module can effectively prevent the impact of too high voltages or electric current, while filter out extraneous interference, and then to this Device is protected, and is prolonged the service life, it is ensured that traffic safety.The plan of establishment of anti-throw load protection circuit module can be taken Increase a TVS protection pipe on DC/DC voltage transformation modules and absorb instant high-voltage and instantaneous large-current, or increases electrolytic capacitor Absorb the measures such as the parasitic capacitance coupling of electric wire.

Description of the drawings

Fig. 1 is the electrical block diagram of the utility model embodiment.

Specific implementation mode

The technical solution of the utility model is described further with reference to Fig. 1.

A kind of electronic type vacuum pressure controller, including control module, control module include signal processing circuit, control Module is connected with output module, DC/DC voltage transformation modules and pressure acquisition circuit module, and DC/DC voltage transformation modules include There is anti-throw load protection circuit module.

Pressure acquisition circuit module includes anti-throw load protection circuit module.Pressure acquisition circuit module docks vacuum Pump, equally will receive the impact of vehicle-mounted voltage, and circuit module is protected by adding anti-throw load, can effectively prevent too high voltages or The impact of electric current, while extraneous interference is filtered out, and then the present apparatus is protected, prolong the service life, it is ensured that traffic safety.

Electronic type vacuum pressure controller is made using semiconductor chip.Controller uses service life lasting semiconductor core Piece, while conditioned amplification and temperature drift, can be such that the precision of product greatly improves, and action frequency is at 1,000,000 times or more.

Output module includes relay control module and alarm output module.Relay control module output relay is cut-off Signal is to control the start and stop of vacuum pump, and preferably, connection solid-state relay is to improve the fan-out capability of product；Alarm output module connects Be informed of a case alarm device such as buzzer etc., to it is under-voltage situations such as carry out controlling alarm.

Obviously, the above embodiment of the present invention is intended to be merely illustrative of the present example, and not to the present invention Embodiment restriction.For those of ordinary skill in the art, it can also make on the basis of the above description Other various forms of variations or variation.There is no need and unable to give poor example to all embodiments.And these belong to this The connotation changes and variations that derived from of invention still fall within protection scope of the present invention.
