Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Fig. 1 shows a schematic diagram of a prior art fuel tank control circuit. As shown in fig. 1, the fuel tank control circuit is connected to the vehicle power supply circuit 100, and the vehicle power supply circuit 100 is powered on after the entire vehicle is powered on.
The tank control circuit includes a tank selection switch 101, and the tank selection switch 101 may be, for example, a rocker switch. The tank selector switch 101 as shown is a double pole single throw switch directly connected to the tank diverter valve assembly 102. The vehicle fuel gauge 6 is used to display the remaining amount of fuel in two fuel tanks in the vehicle under the control of the tank switching valve assembly 102, the first fuel amount sensor 5 is used to detect the remaining amount of fuel in the first fuel tank, and the second fuel amount sensor is used to detect the remaining amount of fuel in the second fuel tank.
When the tank select switch 101 is flipped from right to left, the led indicator light connected to the tank select switch 101 is turned on. At this time, the pin D of the tank switching valve assembly 102 is connected to the positive side, the pin E of the tank switching valve assembly 102 is connected to the negative side, the tank switching valve assembly 102 is operated to switch the fuel tank used by the engine to the second fuel tank, and the inside of the tank switching valve assembly 102 is electrically switched, so that the vehicle fuel gauge 6 displays the remaining fuel amount in the second fuel tank detected by the second fuel amount sensor 4. When the tank selector switch 101 is toggled from left to right, the led indicator lights go off. At this time, the combined pin D of the tank switch valve assembly 102 is connected to the negative pin and the pin E is connected to the positive pin, the tank switch valve assembly 102 is operated to switch the tank used by the engine to the first tank, and the circuit inside the tank switch valve assembly 102 is switched to realize that the vehicle fuel gauge 6 displays the remaining fuel amount in the first tank detected by the first fuel amount sensor 5.
Since the power inside the tank switching valve assembly 102 is provided by the electric motor, and the rated power of the electric motor may be generally 36W, the surge current which may be generated when the tank switching valve assembly 102 operates may be greater than 6A, and generally exceeds the normal tolerance range of the existing rocker switch for vehicles, that is, the tank selector switch 101 is likely to cause a short-circuit fault due to the surge current, and thus the tank switching valve assembly 102 may also be shorted into the power supply circuit of the vehicle, thereby affecting the safety of the vehicle.
The present disclosure proposes a tank control circuit that can address the deficiencies of the prior art tank control circuit as shown in fig. 1. Fig. 2 is a schematic diagram illustrating a tank control circuit according to an exemplary embodiment of the present disclosure.
The oil tank control circuit is also connected to the vehicle power supply circuit 100, and the vehicle power supply circuit 100 can supply power to the oil tank control circuit when the whole vehicle is powered on. The oil tank controlled by the oil tank control circuit comprises a first oil tank and a second oil tank. As shown in fig. 2, the tank control circuit includes: a first switch S1, a voltage switching module 2, and a tank switching valve 1. One end of the first switch S1 is connected to the vehicle power supply circuit 100, and the other end is connected to the voltage switching module 2, and is configured to control on/off between the voltage switching module 2 and the vehicle power supply circuit 100. For example, after the user controls the vehicle to power on, the vehicle power supply circuit 100 is also powered on, and at this time, the power on or off of the voltage switching module 2 can be controlled by opening or closing the first switch S1. The first switch S1 may be any type of switch as long as it is a switch that can facilitate the user' S control of the opening and closing operations.
The voltage switching module 2 is connected to the first pin 11 and the second pin 12 of the tank switching valve 1, and configured to output a positive voltage to the first pin 11 and a negative voltage to the second pin 12 when the power supply on the vehicle power supply circuit 100 is turned on, so that the tank switching valve controls the second tank to supply oil to the engine, and output a negative voltage to the first pin 11 and output a positive voltage to the second pin 12 when the power supply on the vehicle power supply circuit 100 is turned off, so that the tank switching valve controls the first tank to supply oil to the engine. The power supply source on the vehicle power supply circuit 100 may be, for example, a vehicle battery.
That is, in the case that the entire vehicle is powered on, the user closes the first switch S1, so that the voltage switching module 2 is powered on, and then the voltage switching module 2 makes the first pin 11 of the tank switching valve 1 connect positive, and makes the second pin 12 of the tank switching valve 1 connect negative, so that the tank switching valve 1 switches the tank supplying oil to the engine to the second tank; in the case that the user turns off the first switch S1, the voltage switching module 2 is not powered, and the voltage switching module 2 makes the first pin 11 of the tank switching valve 1 negative and the second pin 12 of the tank switching valve 1 positive, so that the tank switching valve 1 can switch the tank for supplying oil to the engine to the first tank. In the case that the entire vehicle is not powered on, the vehicle power supply circuit 100 is not powered on, so that the first switch 1 is not operated to control the tank switching valve 1 to switch the tank at this time.
Through the technical scheme, when the user needs to switch the oil tank of fuel feeding, it can directly carry out the closure or disconnection operation with this first switch, under the circumstances of whole car electricity on, the voltage switching module can come to output different voltages to the oil tank change-over valve according to the break-make of this first switch, thereby realize carrying out the function of switching over between two fuel feeding oil tanks through this oil tank change-over valve control, the user need not again through directly carrying out the switching of fuel feeding oil tank to mechanical valve, and because the oil tank change-over valve is not directly continuous with this first switch, consequently also can not appear because the current impact of oil tank change-over valve leads to the switch short circuit, thereby lead to the oil tank control circuit short circuit, and then influence the circumstances of whole car circuit safety, still further ensured circuit safety under the circumstances of making the switching of oil tank more convenient.
FIG. 3 is a schematic diagram illustrating a tank control circuit according to an exemplary embodiment of the present disclosure. As shown in fig. 3, the voltage switching module 2 includes: a first relay K1, a second relay K2 and a direct current power supply 21. One ends of the coils in the first relay K1 and the second relay K2 are respectively connected with the first switch S1, and the other ends are grounded; a normally open stationary contact in the first relay K1 and a normally closed stationary contact in the second relay K2 are connected to the dc power supply 21, a normally closed stationary contact in the first relay K1 and a normally open stationary contact in the second relay K2 are grounded, a movable contact in the first relay K1 is connected to the first pin 11 of the tank switching valve, and a movable contact in the second relay K2 is connected to the second pin 12 of the tank switching valve.
The dc power supply 21 may be a separate dc power supply, or may be a power supply on the vehicle power supply circuit 100, that is, may be a vehicle battery, and the schematic diagram of the fuel tank control circuit at this time may be as shown in fig. 4, where a normally open stationary contact in the first relay K1 and a normally closed stationary contact in the second relay K2 are connected to the vehicle power supply circuit 100. When the dc power supply 21 is a single dc power supply, the dc power supply may also be disconnected to supply power to the normally open stationary contact of the first relay K1 and the normally closed stationary contact of the second relay K2 when the entire vehicle is powered off.
The circuit states shown in fig. 3 and 4 are the connection states of the first relay K1 and the second relay K2 in the voltage switching module 2 in the case where the first switch S1 is open. The first pin 11 of the tank switching valve 1 is connected to the normally closed stationary contact of the first relay K1 via the movable contact of the first relay K1, and is grounded, so that the first pin 11 of the tank switching valve 1 is grounded in this state. And the second pin 12 in the tank switching valve 1 is connected to the normally closed stationary contact in the second relay K2 through the movable contact of the second relay K2, and is further connected to the dc power supply 21, so that the second pin 12 in the tank switching valve 1 is positive in this state. At this time, the change-over valve 1 can control the supply tank of the engine to be the first tank.
After the whole vehicle is powered on, under the condition that electricity exists in the vehicle power supply circuit 100, the first switch S1 is closed, the coils in the first relay K1 and the second relay K2 are powered on, and the movable contacts in the two relays are attracted to be connected with the normally-open fixed contact, so that the first pin 11 of the oil tank switching valve 1 is connected positively, the second pin 12 is grounded, the oil tank switching valve 1 can be controlled to switch the oil tank for supplying oil to the engine from the first oil tank to the second oil tank, and when the oil tank for supplying oil needs to be switched back to the first oil tank from the second oil tank, the first switch S1 is switched off.
Through setting up first relay K1 and second relay K2 in order realizing the control to this oil tank change-over valve 1, and in two kinds of states after the oil tank switches over, when using the oil in the first oil tank, first relay K1 and second relay K2 in this voltage switching module 2 are in inoperative acquiescence state, only when need switch over to the second oil tank and carry out the oil feed, this first relay K1 and second relay K2 are in operating condition, can reduce whole car load like this effectively, and can increase the life of this first relay K1 and second relay K2.
In one possible embodiment, the tank control circuit may be applied in a dual chamber tank using diesel fuel, the diesel fuel in the first tank may be higher in grade than the diesel fuel in the second tank, e.g., 0# diesel fuel in the first tank, and less than 0# diesel fuel in the second tank, e.g., -10# diesel fuel, -20# diesel fuel, etc. When the vehicle is running in an environment with a temperature of 0 ℃ or higher, the user does not need to switch the oil tank, but the oil tank in the first oil tank can be directly used, and when the vehicle is running in an environment with a low temperature, the oil tank can be switched through the first switch S1, so that the situation that the oil in the first oil tank is condensed and the vehicle cannot be started when the temperature is too low is prevented. Specifically, before the vehicle is turned off, the user can switch the fuel supply tank to the second fuel tank by closing the first switch S1, and then turn off the vehicle again, so as to prevent the fuel from the first fuel tank from condensing in the fuel pipe and failing to start the vehicle when the vehicle is started next time. In this case, after the user switches the first oil tank to the second oil tank, at least a period of time is required for the vehicle to be in the starting state, so as to ensure that all the oil in the oil circuit of the vehicle can be replaced by the oil in the second oil tank, and therefore, a schematic diagram of a tank control circuit according to another exemplary embodiment of the present disclosure is shown in fig. 5, so as to assist the user in grasping the oil tank switching state and the required time length for oil tank switching.
As shown in fig. 5, the control circuit further includes a control unit 3, and a first indicator light D1, wherein the control unit 3 is connected to the tank switching valve 1, and is configured to control the first indicator light D1 to be turned on when the first pin 11 of the tank switching valve 1 is connected to the positive pole and the second pin 12 of the tank switching valve 1 is connected to the negative pole. The control unit 3 can control the first indicator light D1 to indicate the current tank switching state according to the acquired positive and negative states of the first pin 11 and the second pin 12 of the tank switching valve 1. In this way, the user can not only clearly judge the current switching state of the fuel tank according to the lighting state of the first indicator light D1, but also judge whether the fuel tank switching valve 1 is out of order by whether the first indicator light D1 is on after the first switch S1 is closed, which greatly facilitates troubleshooting of the whole fuel tank control circuit.
In a possible embodiment, the control unit 3 is further configured to control the first indicator light D1 to go out after controlling the first indicator light D1 to be on for a preset time period, wherein the preset time period is used for indicating a required time period for successfully switching from the first tank to the second tank. For example, the preset time period may be 120 s. That is, after the user closes the first switch S1, the control unit 3 will control the first indicator light D1 to light up and then control the first indicator light D1 to turn off after the oil in the oil pipe has been completely replaced by the oil in the second oil tank, so as to effectively prompt the user about the time required for switching the oil tank, and avoid the problem that the vehicle cannot be started in a low-temperature environment due to the fact that the oil tank switching time is too short and the oil pipe is not completely replaced because of insufficient experience of the user.
Fig. 5 also shows a schematic circuit diagram of the fuel tank control circuit for controlling the display content of the vehicle fuel gauge 6, and as shown in fig. 5, the control circuit further includes: a third relay K3, a first fuel quantity sensor 5, a second fuel quantity sensor 4, and a vehicle fuel gauge 6, wherein the first fuel quantity sensor 5 and the second fuel quantity sensor 4 are respectively used for detecting the residual fuel quantity in the first fuel tank and the second fuel tank; one end of a coil in the third relay K3 is connected with the first switch S1, and the other end is grounded, so that the connection with the vehicle power supply circuit 100 can be switched on and off by opening and closing the first switch S1; a normally open static contact of the third relay K3 is connected with the second oil quantity sensor 4, a normally closed static contact of the third relay K3 is connected with the first oil quantity sensor 5, and a movable contact of the third relay K3 is connected with a vehicle fuel gauge 6; the vehicle fuel gauge 6 is also respectively connected with the first fuel quantity sensor 5 and the second fuel quantity sensor 4, and can be used for forming a loop with the first fuel quantity sensor 5 to display the residual fuel quantity of the first fuel tank when a coil in the third relay K3 is not electrified, and can be used for forming a loop with the second fuel quantity sensor 4 to display the residual fuel quantity of the second fuel tank when a coil in the third relay K3 is electrified.
In this way, when the first switch S1 is open, the vehicle uses the oil in the first tank, and the vehicle fuel gauge 6 displays the remaining oil in the first tank according to the first oil quantity sensor 5 in the first tank, and when the second switch S1 is closed, the third relay K3 is powered, and the movable contact in the third relay K3 is attracted to be connected with the normally open stationary contact in the third relay K3, so that the vehicle fuel gauge 6 can display the remaining oil quantity in the second tank according to the second oil quantity sensor 4 in the second tank. Moreover, the vehicle fuel gauge 6 and the tank switching valve 1 are not directly connected, so that the residual fuel quantity displayed by the vehicle fuel gauge 6 can be correspondingly switched while the fuel tank is switched, and the accurate display of the residual fuel quantity of the fuel tank in the vehicle fuel gauge 6 cannot be influenced no matter whether the tank switching valve 1 fails or not.
In addition, the oil tank control circuit shown in fig. 5 further comprises a second switch S2 for heating the electromagnetic valve 7; one end of the heating electromagnetic valve 7 is connected with the vehicle power supply circuit 100 through the second switch S2, the other end of the heating electromagnetic valve is grounded, connection and disconnection between the heating electromagnetic valve 7 and the vehicle power supply circuit 100 can be achieved according to opening and closing of the second switch S2, and the heating electromagnetic valve 7 can control heating of the first oil tank when electrified. The user can actively control the heating of the first oil tank through the heating solenoid valve 7 by opening and closing the second switch S2 according to the user' S requirement. Therefore, the heating of the oil tank can be facilitated, the influence of the working state of other vehicle equipment is avoided, and the starting and stopping of the heating and the duration of the continuous heating can be controlled by a user completely.
