[0002] The air pump control system is an important part of the power supply of new energy vehicles. The air pump needs to be controlled in conjunction with the dryer. If the stop air pressure node of the air pump is too low, it will not be able to reach the exhaust air pressure of the dryer. If it is too high, it will cause The exhaust function of the dryer has been working

Embodiment Construction
[0013] Attached below figure 1 The present invention will be further described.
[0014] The air pump delay control device includes:
[0015] The main relay 4, one of its control ends is connected to the power supply through the air pump switch 2, and the other control end is grounded through the pressure switch 1; the delay relay 5, one of its control ends is connected to the normally closed output end of the main relay 4, and the other The control terminal is grounded; one end of the air pump 3 is grounded, and the other end is respectively connected to the normally open output end of the main relay 4 and the output end of the delay relay 5; the input end of the main relay 4 and the input end of the delay relay 5 are respectively passed The air pump switch 2 is connected to the power supply. Adjust the maximum air pressure of the pressure switch 1 according to the air pressure value required by the vehicle. When the air pump switch 2 is closed, if the air pressure reaches ...

The invention provides an air pump delaying control device. The air pump delaying control device comprises a main relay, a delaying relay and an air pump. The highest air pressure of a pressure switch is adjusted according to an air pressure value needed by a whole vehicle; after an air pump switch is switched off, the pressure stitch is switched off if the air pressure reaches the best air pressure, a coil of the delaying relay is electrified and sucked, the air pump is communicated with a power supply and starts to work; the delaying relay is switched off after a certain period of delaying and the air pump is switched off, so that gas of a dryer can be smoothly exhausted and the air pump can be automatically switched off after continually working for a certain time. When the air pressure is lower than preset pressure, the pressure switch is switched on and a coil of the main relay is electrified to work; the air pump is electrified with the power supply by a normally open end of the main relay, and the exhausting air pressure of the dryer can be smoothly reached when the air pump starts to work.
Description
technical field [0001] The invention relates to the technical field of automobile control devices, in particular to an air pump control device. Background technique [0002] The air pump control system is an important part of the power supply of new energy vehicles. The air pump needs to be controlled in conjunction with the dryer. If the stop air pressure node of the air pump is too low, it will not be able to reach the exhaust air pressure of the dryer. If it is too high, it will cause The exhaust function of the dryer has been working. Contents of the invention [0003] In order to overcome the shortcomings of the above technologies, the present invention provides an air pump delay control device that can make the dryer exhaust smoothly after the air pump switch is turned off and automatically shut down after exhaust. [0004] The technical scheme that the present invention overcomes its technical problem adopts is: [0005] The air pump delay control device includes:...
