The accompanying drawing explanation
Fig. 1 shows the circuit diagram of the wiper control circuit of conventional commercial car.
Fig. 2 shows the circuit diagram of wiper control circuit described in the utility model.
The specific embodiment
Below describe embodiment of the present utility model in detail, the example of described embodiment is shown in the drawings, and wherein same or similar label means same or similar element or the element with identical or similar functions from start to finish.Be exemplary below by the embodiment be described with reference to the drawings, only for explaining the utility model, and can not be interpreted as restriction of the present utility model.
Fig. 2 shows the circuit diagram of wiper control circuit described in the utility model.As shown in Figure 2, the wiper control circuit comprises combined switch, slow-speed relay J1, fast relay J2, rain shaving electrical machine M1 and washing motor M2, described combined switch is connected with the low speed control end pin LO of rain shaving electrical machine M1 by slow-speed relay J1, described combined switch is connected with the High-speed Control end pin HI of rain shaving electrical machine M1 by fast relay J2, and described combined switch is electrically connected to described washing motor M2.
Especially, described control circuit also comprises main control module, and for the intermitten of realizing windscreen wiper and washing and windscreen wiper linkage action intermittently, described main control module is a kind of in central process unit (CPU), micro controller system, flush bonding processor.Particularly:
On the one hand, described main control module is electrically connected to combined switch and slow-speed relay J1 respectively, when combined switch is pushed while intermittently keeping off, main control module sends the control signal at an intermittence to the control end of slow-speed relay J1, make slow-speed relay J1 adhesive off and on, thereby realize the intermitten of windscreen wiper.
On the other hand, described main control module also is electrically connected to the counting machine of washing motor M2 and time of being pressed for the wash button of monitoring combined switch respectively, and described counting machine is preferably the counter chip that counter chip that model is 74LS161 or model are 74LS160.For example, when the value of described counting machine is greater than a setting value (500ms), described master control module controls washing motor M2 action, carry out the water spray action, after water spray, main control module sends the control signal at an intermittence to the control end of slow-speed relay J1, make slow-speed relay J1 adhesive off and on, thereby realize intermittently linkage action of washing and windscreen wiper.
Further, described wiper control circuit also comprises main relay J3, and described slow-speed relay J1 is connected with power supply by described main relay J3 respectively with fast relay J2.With reference to Fig. 2, main relay J3 is controlled by control end power supply 1 and working end power supply 2, controlling power supply 1 is provided by ignition lock ACC gear and ON gear, working power 2 directly provides by battery feed, when ignition lock is got to the ACC/on gear, control power supply 1 power supply, main relay J3 adhesive, windscreen wiper enters treats mode of operation.The benefit of this kind of design is, setting due to main relay J3, slow-speed relay J1 and fast relay J2, have avoided reducing due to the life-span caused in energising for a long time in treating mode of operation without energising in real time, have improved the work life of slow-speed relay J1 and fast relay J2.
Below the control process of detailed described automotive control circuit:
When combined switch is got to bottom gear, slow-speed relay J1 adhesive, windscreen wiper enters the slow running state.When combined switch is got to top gear, fast relay J2 adhesive, rain shaving electrical machine M1 enters the high speed operation state.
Get to intermittently gear when combined switch, main control module sends the control signal at an intermittence to the control end of slow-speed relay, control slow-speed relay J1 adhesive off and on, makes rain shaving electrical machine M1 in the low speed mode of operation at intermittence.
When the wash button of pressing on combined switch surpasses 500ms, at first master control module controls washing motor M2 carries out the water spray action, then controls slow-speed relay J1 adhesive off and on.
In addition, when intermittently order and washing commands trigger simultaneously, washing function is preferential.
Embodiment shown in above foundation is graphic describes structure of the present utility model, feature and action effect in detail; the foregoing is only preferred embodiment of the present utility model; but the utility model does not limit practical range with shown in drawing; every change of doing according to conception of the present utility model; or be revised as the equivalent embodiment of equivalent variations; when not exceeding yet specification sheets and illustrating contain spiritual, all should be in protection domain of the present utility model.
