Referring to fig. 1, fig. 1 is a functional block diagram of a connection start device according to an embodiment of the disclosure. As shown in fig. 1, an actuating connection device 100 provided by the embodiment of the present disclosure includes a power connection terminal 10, a load connection terminal 20, and a first switch circuit 30. The power connection terminal 10 is configured to be electrically connected to a power module (not shown), the load connection terminal 20 is configured to be electrically connected to an external load (not shown), and the first switch circuit 30 is electrically connected between the power connection terminal 10 and the load connection terminal 20.
The power supply component may be any one of a dc power supply, a battery pack, or a super capacitor, which is not limited herein.
The power connection terminal 10, the load connection terminal 20, and the first switch circuit 30 constitute a current output circuit 11 in which the power module supplies power to the external load, and the first switch circuit 30 is used to turn on or off the current output circuit 11. As such, the power supply assembly may provide power to the external load through the start-up connection device 100.
In the embodiment of the present disclosure, the power connection terminal 10 includes a power positive connection terminal BAT + and a power negative connection terminal BAT-, wherein the power positive connection terminal BAT + and the power negative connection terminal BAT-are used for being electrically connected to the positive electrode and the negative electrode of the power module in a one-to-one correspondence manner. The power supply unit is connected to the start-up connection 100 via the power connection 10, so as to provide the start-up connection 100 with an operating voltage and to supply the external load via the first switching circuit 30.
The load connection terminal 20 includes a load positive connection terminal CAR + and a load negative connection terminal CAR-, wherein the load positive connection terminal CAR + and the load negative connection terminal CAR-are electrically connected to the positive electrode and the negative electrode of the external load in a one-to-one correspondence, and the load negative connection terminal CAR-is also electrically connected to the first ground terminal. The external load may be an automobile battery or an automobile starter. It is understood that the automotive battery includes, but is not limited to, lead-acid batteries, lithium iron phosphate batteries, ultracapacitors, and the like.
Referring to fig. 2, fig. 2 is a functional block diagram of a starting connection device for supplying power to a vehicle according to an embodiment of the disclosure. As shown in fig. 2, the external power source 600 may emergency start the automobile 900 by starting the connection device 100. It can be understood that under normal conditions, the automobile battery 300 is connected with the automobile starter 400 for starting the automobile 900, when the automobile battery 300 is in power shortage, the connection between the automobile battery 300 and the automobile starter 400 can be disconnected, the starting connection device 100 is connected with the automobile starter 400, and then the automobile is started, so that the automobile engine 500 works; or the automobile battery 300 is connected with the starting connecting device 100 in parallel and then connected with the automobile starter 400, and then the automobile 900 is started. That is, when the automobile battery 300 is disconnected from the automobile starter 400, the external load is the automobile starter; when the automobile battery 300 and the automobile starter 400 are not disconnected, the external load is the automobile battery.
Referring to fig. 1 again, the starting connection device further includes a controller 40, a voltage source module 50, a second switch circuit 60 and a voltage detection module 70.
The controller 40 is electrically connected to the first switch circuit 30, wherein the first switch circuit 30 enters a conductive state when receiving a driving signal output from the controller 40. The voltage source module 50 is configured to output a first voltage. Illustratively, the first voltage may be 3V or 5V, which is not limited herein.
The second switch circuit 70 is electrically connected between the voltage source module 50 and the load connection terminal 20, and receives a first control signal output by the controller 40, and the first control signal is used for controlling the second switch circuit 60 to be alternately turned on and off.
In some embodiments, the first control signal is comprised of alternating high and low level signals. Illustratively, the first control signal may be a Pulse Width Modulation (PWM) signal, wherein the PWM signal includes a plurality of Pulse signals with equal amplitude but different widths.
The voltage detection module 70 is electrically connected to the load output terminal 20, and configured to detect voltages of the load connection terminal 20 in the states of alternately turning on and off the second switch circuit 60, respectively, and the controller 40 is further electrically connected to the voltage detection module 70, and configured to identify whether the load connection terminal 20 is connected to an external load and a type of the connected external load according to the voltage detected by the voltage detection module 70, and control the start connection device 100 to enter a start mode corresponding to the type of the external load when it is determined that the load connection terminal 20 is connected to the external load.
When the positive connection end and the negative connection end of the load connection end 20 are not connected to an automobile battery or an automobile engine, the controller 40 controls the second switch circuit 60 to be turned on or off by outputting the first control signal, so as to control the voltage source module 50 to intermittently output the first voltage, that is, the voltage source module 50 may periodically output the first voltage to the load connection end 20, wherein the time for turning on the output voltage and the time for turning off the output voltage may be set according to actual conditions, that is, the duration time of the high level signal and the low level signal of the first control signal may be adjusted according to specific requirements, for example, the duty ratio of the PWM signal may be adjusted.
If the voltage detection module 70 detects that the voltage value of the load connection end 20 is the same as the voltage value of the voltage source module during the period that the voltage source module 50 starts outputting the voltage, the load connection end 20 is considered not to be connected with the automobile battery 300 or the automobile starter 400 at the moment; if the voltage detection module 70 detects that the voltage value of the load connection terminal 20 does not change during the period that the voltage source module 50 is disconnected from the output voltage, it is also determined that the load connection terminal 20 is not connected to the automobile battery 300 or the automobile starter 400, and the voltage source module 50 continues to be controlled to periodically output the voltage.
In some embodiments, if the voltage detection module 70 detects that the voltage of the load connection terminal 20 is greater than a first preset voltage value during the second switch circuit 60 is in the off state, the controller 40 determines that the load connection terminal 20 is connected to a power supply type load, and the controller 40 controls the start-up connection device 100 to enter the first start-up mode. The power supply type load refers to a power supply type load capable of providing energy, and in the embodiment of the disclosure, the power supply type load is an automobile battery 300.
The first preset voltage value may be set according to a model, a specification, and the like of a load product connected to the load connection end 20, for example, the first preset voltage value may be 0.6V, which is not limited herein.
It can be understood that, since the voltage value of the load connection terminal 20 is about 0V during the disconnection period of the second switch circuit 60, if the voltage detection module 70 detects that the voltage value of the load connection terminal 20 is greater than the first preset voltage value during the period, it indicates that the load connection terminal 20 is connected to the power supply type load.
It should be noted that 0V in the embodiment of the present disclosure represents the voltage value of the load connection terminal 20 when the second switch circuit 60 is in the open state and the load connection terminal 20 is in the no-load state, however, in practical cases, the voltage value of the load connection terminal 20 may be 0V, or may be a very small value.
In some embodiments, if the voltage detection module 70 detects that the voltage of the load connection terminal 20 is between the second preset voltage value and the third preset voltage value during the second switch circuit 60 is in the on state, the controller 40 determines that the load connection terminal 20 is connected to the power consumption type load, and controls the start-up connection device 100 to enter the second start-up mode. The power consuming load refers to a load that consumes electric energy, and in the embodiment of the present disclosure, the power consuming load may be an automobile starter 400.
The third preset voltage value is a voltage value of the load connection end in a no-load state, that is, a voltage value of the voltage source, and the second preset voltage value may be 0.5V, it should be noted that if the second preset voltage value is too small, a short circuit or an overcurrent of the load may be mistaken as normal, and therefore when the load is set, attention needs to be paid to avoid the situation that the value is too small.
It can be understood that, since the voltage value of the load connection terminal 20 is the voltage value of the voltage source module 50 during the period that the second switch circuit 60 is in the on state, if it is detected that the voltage of the load connection terminal 20 is greater than the second preset voltage value and less than the voltage value of the voltage source module 50 during the period, it is indicated that the external load connected to the load connection terminal 20 shares a partial voltage, that is, the external load is a power consumption type load.
In this embodiment, the accuracy of determining the external load type can be improved by determining whether to switch on the power supply type load by detecting whether the voltage of the load connection terminal 20 is greater than the first preset voltage value during the off state of the second switch circuit 60, and determining whether to switch on the power consumption type load by detecting whether the voltage of the load connection terminal 20 is between the second preset voltage value and the third preset voltage value during the on state of the second switch circuit 60.
Referring to fig. 3, fig. 3 is a schematic diagram of another functional module for activating a connection device according to an embodiment of the present disclosure. In some embodiments, the start-up junction device 100 further includes a current detection module 90. The current detection module 90 is electrically connected between the power supply negative connection terminal BAT-and the load negative connection terminal CAR-for detecting a current state of the output circuit 11, and is connected to the controller 40.
In the embodiment of the present disclosure, in the first start mode, the controller 40 stops outputting the first control signal, so that the second switch circuit 60 is in an off state, at this time, the controller 40 outputs the driving signal to control the first switch circuit 30 to be in an on state and continue for a first preset time, where the first preset time may be manually set according to an actual situation.
The controller 40 controls the first switch circuit 30 to be continuously turned on or off according to the current state of the output circuit 11 detected by the current detection module 90 within the first preset time.
Illustratively, as shown in fig. 3, the current detection module 90 is electrically connected to the output circuit 11 for detecting the output current of the output circuit 11. If the output current is greater than the first preset current value, it indicates that the automobile starter 400 is in a working state, and the controller 40 needs to continuously output the driving signal to control the first switch circuit 30 to be kept in a conductive state for a second preset time, so that the automobile 900 is started. The second preset time is related to the time required by starting the automobile, and can be specifically set according to different types of automobiles.
If the current detection module 90 detects that the output current of the output circuit 11 is not greater than the first preset current value within the first preset time, it indicates that the vehicle starter is not in a working state, that is, the vehicle is not started at this time, and after the first preset time, the controller 40 stops outputting the driving signal to control the first switch circuit 30 to be in an off state and to continue for a third preset time. Therefore, the situation that the power supply assembly is continuously discharged under the condition that the starter does not work can be avoided.
For example, the first preset current value may be set according to actual conditions, such as 0.5A, 1A, and the like, and is not limited herein. The second preset time may be preset, for example, 5 seconds, 10 seconds, and the like, and is not limited herein. The third preset time may be set manually, for example, 5 seconds, 10 seconds, and the like, and is not limited herein. The first preset time, the second preset time and the third preset time may be the same or different, and are not specifically limited herein.
It can be understood that, if the output current is not greater than the first preset current value within the first preset time, it indicates that the load connection terminal 20 is connected to the automobile battery 300, but the automobile starter 400 is not started at this time, so that the first switch circuit 30 is controlled to be in the off state, but since the automobile may need to be started while the first switch circuit 30 is in the off state, and only needs to last for a third preset time, that is, after the first switch circuit 30 is in the off state and lasts for the third preset time, the controller 40 outputs the driving signal to control the first switch circuit 30 to be in the on state and last for the first preset time, so as to and fro, not only the output circuit can be opened when the automobile is not started, but also the output circuit can be closed when the automobile is started, to start the car in an emergency.
In some embodiments, if it is detected that the output current of the output circuit is greater than the second preset current value within the first preset time, it indicates that the output circuit is in an overcurrent condition, and at this time, the first switch circuit needs to be turned off to stop supplying power to the load, so as to ensure the safety of power supply. Wherein the second preset current value is greater than the first preset current value.
It can be understood that if the output current of the output circuit is detected to be greater than the second preset current value within the first preset time, it indicates that the output circuit is short-circuited, and in order to avoid a safety risk caused by the short-circuit of the starting connection device, the first switch circuit 30 should be turned off.
In some embodiments, in the third preset time, if the voltage detection module 90 detects that the voltage of the load connection terminal 20 is less than a fourth preset voltage value, it indicates that the battery of the vehicle is disconnected from the starting connection device 100, that is, the starting connection device 100 has been removed from the vehicle, at this time, the controller 40 controls the starting connection device 100 to exit from the first starting mode, and return to the initial detection state.
The fourth preset voltage value is smaller than the first preset voltage value, for example, when the first preset voltage value is 0.6V, the fourth preset voltage value may be 0.4V.
In some embodiments, in the second start mode, the controller 40 stops outputting the first control signal, so that the second switch circuit 60 is in an off state, i.e., controls the voltage source module 50 to stop outputting the voltage. The controller 40 further outputs the driving signal to control the first switch circuit 30 to be in a conducting state, and controls the duration of the conducting state of the first switch circuit 30 to be a fourth preset time, wherein the fourth preset time is set as a starting time required for starting the engine of the automobile, and in addition, the fourth preset time can be set according to actual conditions, for example, for different automobiles, the starting time may be different, and the fourth preset time can be set according to automobiles of different brands. And after the duration time of the on state of the first switch circuit 30 is a fourth preset time, stopping outputting the driving signal, that is, controlling the first switch circuit 30 to be switched off, further controlling the output loop 11 to be switched off, and controlling the starting connection device to exit from the second starting mode.
The fourth preset time may be preset, for example, 5 seconds, 10 seconds, and the like, and is not limited herein.

In some embodiments, the Controller 40 may be any type of Programmable Logic Controller (PLC), such as a Microcontroller (MCU), a Programmable Logic Array (FPGA), a Digital Signal Processor (DSP), or the like, without limitation. The controller 40 is used as a logic operation and control center of the starting connection device 100, and is mainly responsible for data acquisition and conversion, logic operation, data communication, execution of drive output and other functions.
The operation of the actuating connecting device 100 will be explained below.
Referring to fig. 6 again, as shown in fig. 6, during the operation of the starting connection device 100, a power supply component inputs a voltage to the power conversion module 80 through the power connection terminal 10, and the first voltage VCC output by the power conversion module 80 (i.e., the output voltage of the voltage source module 50) is used for supplying power to each module of the starting connection device 100.
During the no-load state of the load connection terminal 20, the controller 40 outputs a first control signal through the third pin 3 to control the second driving module 62 to be periodically turned on and off. Specifically, when the first control signal is a high level signal, the NPN digital transistor Q3 is turned on, and since the emitter of the NPN digital transistor Q3 is grounded, when it is turned on, the gate of the P-type MOS fet Q2 in the second electronic switch 61 is at a low voltage, so that the P-type MOS fet Q2 is turned on, and the voltage source module 50 can output the first voltage VCC to the load connection terminal, so that the load connection terminal 20 is at a high voltage state; when the first control signal is a low level signal, the digital transistor Q3 is in an off state, and the P-type MOS fet Q2 is also in an off state, and at this time, the load connection terminal 20 is in a low voltage state without receiving the first voltage.
Thus, if the 5 th pin of the controller 40 detects that the voltage of the load connection terminal 20 is greater than the first preset voltage value during the period that the voltage source module 50 is disconnected from the output, it indicates that the load connection terminal 20 is connected to a power supply type load (i.e., an automotive battery), and at this time, the controller 40 controls the starting connection device 100 to enter the first starting mode.
In a first start mode, the controller 40 outputs the driving signal (high level signal) to the first driving module 32 through the first pin 1, and since the first transistor Q1 in the first driving module 32 is an N-type MOS fet, the control end of the first transistor Q1 is at a high level, the first transistor Q1 is turned on, the voltage of the second connection end of the first resistor R1 is 0V, meanwhile, the level of the fourth connection end 4 of the relay K1 in the first electronic switch 31 is at a low level, the level of the third connection end 3 of the relay K1 is at a high level, the coil in the relay K1 has a current passing therethrough, and the coil generates a magnetic field to attract the single-pole single-throw switch to be closed, so that the output loop 11 is turned on and continues for a first preset time.
The current detection module 90 detects a current signal in the output loop 11, and when the controller 40 detects that the current in the output loop 11 is greater than a first preset current value through the second pin 2, the controller 40 continuously outputs the driving signal to turn on the output loop 11 for a second preset time; when the controller 40 detects that the current in the output circuit 11 is not greater than the first preset current value, the controller 40 stops outputting the driving signal after the first preset time is reached, so that the first switch circuit 30 is in the off state and continues for a third preset time, that is, the output circuit 11 is in the off state.
Within a third preset time when the first switch circuit 30 is in the off state, if the 5 th pin of the controller 40 detects that the voltage of the load connection end 20 is smaller than a fourth preset voltage value, it indicates that the automobile battery is disconnected from the load connection end 20 at the moment, and at the moment, the controller 40 controls the starting connection device 100 to exit from the first starting mode.
If the voltage value of the load connection terminal 20 is detected between the second preset voltage value and the third preset voltage value (i.e. the voltage value is greater than the second preset voltage value and less than the first voltage VCC) by the pin 5 of the controller 40 during the period of starting the output of the voltage source module 50, it indicates that the load connection terminal 20 is connected to the power consumption type load (i.e. the vehicle starter), and at this time, the controller 40 controls the start-up connection device 100 to enter the second start-up mode.
In the second start mode, the controller 40 outputs the driving signal through the first pin 1, that is, the controller 40 controls the output loop 11 to be in a conducting state for a fourth preset time; after a fourth preset time, the controller 40 stops outputting the driving signal, i.e. controls the output circuit 11 to be in the disconnected state, and controls the start-up connection device 100 to exit from the second start-up mode.
In this embodiment, the specific circuit of each unit is not limited as long as each unit can realize the corresponding function. In addition, each unit may be integrated on the same circuit substrate and disposed in the same casing, or integrated on different circuit substrates and disposed in different casings, which may be combined according to actual situations, and is not limited herein.
