The utility model is capable of other and different embodiments and of being practiced or of being carried out in various ways, and its several details are capable of modification in various respects, all without departing from the spirit and scope of the present invention. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict.
It should be noted that the drawings provided in the following embodiments are only for illustrating the basic idea of the present invention, and the components related to the present invention are only shown in the drawings rather than drawn according to the number, shape and size of the components in actual implementation, and the type, quantity and proportion of the components in actual implementation may be changed freely, and the layout of the components may be more complicated.
Referring to fig. 1, a schematic diagram of a control circuit for a power supply cut-off circuit of an automobile according to the present invention includes:
wherein, the car power supply shutdown circuit includes: the ignition control system comprises an engine controller 1, a power control switch 2, an ignition switch 3, a power control device actuator 4, a generator 6 and a storage battery 5, wherein the storage battery 5 is respectively connected with the input ends of the engine controller 1, the power control switch 2 and the power control device actuator 4 to supply power to the engine controller, the power control switch 2 and the power control device actuator 4; the engine controller 1 is sequentially connected with an ignition switch and a power supply control switch 2; the power control switch 2 is connected with the power control device actuator 4, and the power control device actuator 4 is used for disconnecting power supply between the storage battery and the whole vehicle.
In the present embodiment, the power control switch 2 is connected to the power control device actuator 4 by a power control line, and the power control device actuator 4 cuts off power supply between the battery 5 and the vehicle after receiving a power cut-off signal, so as to cut off power supply between the battery 5 and electrical components of the vehicle in an off state or a vehicle stop state of the vehicle, thereby protecting the electrical components.
On the basis of the above embodiment, the engine controller 1 sequentially connects the ignition switch 3 and the power control switch 2 through the signal line to form a control loop, the power control switch 2 is triggered to generate a trigger signal, the engine controller 1 is connected with the power control switch 2 to receive an extinguishing signal, the engine controller 1 is connected with the engine to send a power cut-off signal, the generator 6 stops generating power and then cuts off power supply between the generator and the whole vehicle, for example, the engine controller 1 can receive a corresponding trigger signal (namely, the extinguishing signal) through the control loop, so that the engine is controlled to stop rotating by sending the power cut-off signal, and the generator stops generating power and then cuts off power supply between the generator and the whole vehicle.
Specifically, the power connection between the generator 6 and the battery 5 and between the generator 6 and various electrical components in the vehicle is cut off by turning off the generator 6.
For example, when the ignition switch 3 is in the ignition position, the ignition switch 3 is powered by the storage battery 5 to trigger the engine, and the generator 6 is driven by the engine to work; according to the electromagnetic induction principle, a rotor inside the generator 6 rotates to generate a rotating magnetic field, three groups of coils are fixed outside the magnetic field on a generator shell, 3-phase windings are separated by 120 degrees, and when the rotor rotates, the rotating magnetic field enables the magnetic flux in the fixed armature winding to change, so that three-phase induced electromotive force is generated in a stator armature winding to realize power generation; the output end of the generator is connected with the storage battery, and a power supply higher than the output voltage of the storage battery is provided to charge the storage battery.
For example, the generator 6 is in an operating state during the running of the vehicle, and the engine controller 1 and the power control device 4 can be simultaneously triggered to operate by the power control switch 2, so that the vehicle power supply and the vehicle power can be surely cut off during the running of the vehicle.
It should be further noted that, as can be seen from the above circuit principle control, after the power control switch is triggered, on one hand, when the power control device actuator 4 receives the first trigger signal, the power control device actuator 4 generates a power cut-off signal to cut off power supply between the storage battery 5 and the entire vehicle, so as to prevent the entire vehicle power supply (storage battery) from being electrically connected to electrical components inside the vehicle after the vehicle is shut down, thereby reducing the probability of occurrence of accidents (fire, explosion, etc.) or abnormalities of the electrical components inside the vehicle, and improving the safety of the vehicle; on the other hand, when the engine controller 1 receives the second trigger signal from the power control switch 2, the engine controller 1 sends a power cut-off signal to control the engine to stop operating, and further, the generator 6 stops generating power.
In other embodiments, further comprising: the generator is connected with the input end of the storage battery 5 and is used for charging the storage battery 5 when the generator 6 works.
Specifically, the generator 6 is driven by the engine to generate power, and also supplies power to the whole vehicle electric equipment, and simultaneously charges the storage battery 5, in other words, the engine drives the generator 6 to generate power in addition to providing power for the vehicle. After the vehicle is started or driven, the engine drives the generator to work together, the engine controller 1 controls the generator 6 to work through a control signal, and after the generator 6 works, the storage battery 5 is connected through a power generation line (such as a power generation line 1 and a power generation line 2 in fig. 1) to charge the storage battery 5.
In other embodiments, further comprising: the memory is connected with the engine controller and used for storing the running records of the automobile.
Specifically, the Memory may include a Random Access Memory (RAM) and may also include a non-volatile Memory (non-volatile Memory), for example, the Memory is connected to the transmitter controller to store the driving record of the vehicle, so that the user can know the driving state of the vehicle conveniently.
