Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example one
Referring to fig. 1 and 4, after the vehicle starts and the battery is short of electricity for a long time or the electric quantity is insufficient to start the vehicle, the external power supply is connected, then the vehicle starts to be started, when the vehicle starts, the starting current is increased instantly, the vibration sensor of the negative electrode clamp clamped on the vehicle body senses strong vibration, and the time delay module starts to start countdown, for example, after 5 seconds of time delay, the time delay module completes the time delay action, and in the 5 seconds, the vibration sensor always detects the strong vibration of the vehicle, which indicates that the vehicle has started, the main processing controller disconnects the switch circuit module in the control box, and the negative electrode circuit of the external power supply is disconnected.
If the vehicle is started, the vibration sensor senses and detects the vibration, but the vibration does not only instantly or does not continue until the delay module finishes the delay action, and the vehicle is failed to start. The automobile starting failure is that the external power supply system carries out self-checking, if the self-checking of the external power supply is not abnormal, the automobile starting battery is quickly charged for a certain time, then secondary starting is carried out, and the automobile starting battery which is charged with a certain electric quantity and the external power supply are simultaneously involved to start the automobile. If the starting still fails after multiple times of starting, the external power supply can enter a slow charging state of the automobile starting battery, or people check the automobile starting battery by themselves.
If the automobile is started successfully, although the starting peak current is increased, the current value does not reach the predicted current value, the main processing controller also sends an abnormal signal to the external power supply self-checking system to enable the external power supply to carry out self-checking.
Example two
Referring to fig. 2, after the external power source is connected to the vehicle starting battery, the external power source is powered on, and at the moment of powering on, the main processing controller receives the rising edge signal, and the main processing controller synchronously turns on the circuit module to complete the electrical circuit communication with the vehicle starting battery.
Referring to fig. 3, a current monitoring module, a vibration signal module, a delay module and a circuit control module are configured in the main processing controller, the current monitoring module is used for monitoring real-time current change of the circuit, the vibration signal module triggers the delay module, and the circuit control module can control on/off of the switch circuit module.
Referring to fig. 4, the control box is installed on the negative line, the negative electrode clip is located at the end of the negative line, and a vibration sensor is further disposed outside the clamping plate of the negative electrode clip and transmits vibration state information on the negative electrode clip to the control box.
EXAMPLE III
When the external power supply is connected to the automobile starting battery in a lap joint mode, a positive electrode clamp of the external power supply is clamped on a positive pole column of the automobile starting battery, then a negative electrode clamp of the external power supply is clamped on a negative electrode iron sheet of an automobile body, and the iron sheet is electrically connected with a negative electrode of the automobile starting battery.
After the automobile is started, the negative electrode clamp needs to be taken down firstly, and then the positive electrode clamp needs to be taken down, because the electrical system of the conventional automobile adopts a single wire system, and the automobile body adopts a mode of being connected with a battery negative electrode 'grounding' in international standard, so that the negative electrode clamp needs to be taken down firstly.
Example four
In the invention, when the external power supply is dismounted, the negative electrode clamp is generally firstly dismounted, and in the invention, a mode that the switch circuit module can disconnect the negative electrode circuit after the automobile is started is designed, so that any electrode clamp can be dismounted at will.
The external power supply is internally provided with a self-checking system for detecting the voltage and the current of the power supply and outputting the real-time voltage and the current information, and the external power supply is provided with a display screen or a reminding module for displaying the real-time voltage and the current state information, for example, the fault information of the external power supply such as undervoltage, overload or short circuit can be displayed through the display screen or the reminding module.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
