Therefore, they should not be understood as limiting the present invention.

[0032] As shown in Figures 1 to 5, the present invention provides an automatic constant high-voltage ignition system for an automobile, comprising an ignition coil 1, a distributor 2, an ignition control module 3, and a spark plug 4. The ignition coil 1 and the distributor 2 are connected via a high-voltage wire, the distributor 2 and the spark plug 4 are connected via a high-voltage wire, and the ignition control module 3 and the ignition coil 1 are communicatively connected. A high-voltage terminal 5, a control terminal 1 6, and a control terminal 2 7 are provided at the top of the ignition coil 1.

[0033] The distributor 2 includes a fixed component 8, a rotating component 9, an advance angle adjustment component 10 and an ignition contact 11. The rotating component 9 is rotatably arranged in the fixed component 8, the advance angle adjustment component 10 is arranged on the rotating component 9, and the ignition contacts 11 are evenly distributed in a ring on the fixed component 8.

[0034] The fixing assembly 8 includes a fixing plate 12 and a driving motor 13 . The driving motor 13 is located below the fixing plate 12 , and a housing of the driving motor 13 is fixedly connected to the fixing plate 12 .

[0035] The rotating assembly 9 includes a rotating terminal 14 and a rotating lever 15. The rotating terminal 14 is rotatably arranged in the fixed disk 12. The rotating terminal 14 is fixedly connected to the output shaft of the drive motor 13. The rotating lever 15 consists of a mounting ring 18 and an elastic conductive sheet 19. The rotating lever 15 is engaged with the rotating terminal 14 through the mounting ring 18. The end of the elastic conductive sheet 19 is provided with a sickle-shaped bending portion 20.

[0036] Through the contact between the sickle-shaped bend portion 20 and the ignition contact 11, power can be supplied to the spark plug 4 to ignite and control the combustion of the combustible gas; by adjusting the bending amplitude of the sickle-shaped bend portion 20, the contact time between the sickle-shaped bend portion 20 and the ignition contact 11 can be advanced or delayed while the rotation process of the drive motor 13 remains unchanged, thereby controlling the advance angle of the igniter 22.

[0037] The advance angle adjustment assembly 10 includes a winding column 16 and a tensioning belt 17 . The winding column 16 is rotatably mounted on an elastic conductive sheet 19 . The tensioning belt 17 is wound around the winding column 16 . The end of the tensioning belt 17 is mounted on a sickle-shaped bent portion 20 .

[0038] The ignition contact 11 is fixed to the fixed plate 12 , and the ignition contact 11 and the spark plug 4 are connected via a high-voltage wire.

[0039] By rotating the winding post 16 , the sickle-shaped bend portion 20 can be pulled by the tensioning belt 17 , thereby changing the shape of the sickle-shaped bend portion 20 in a free state, thereby adjusting and controlling the ignition timing.

[0040] The ignition control module 3 includes a control line 21, an igniter 22 and a feedback control component 23. The igniter 22 and the control terminal 2 7 are connected via the control line 21. The control terminal 1 6 is connected to an external power supply. A transistor is provided inside the igniter 22.

[0041] The feedback control component 23 includes a temperature sensor 25 and an ECU 26 . The ECU 26 and the igniter 22 are in communication with each other, and the temperature sensor 25 and the ECU 26 are in communication with each other.

[0042] The electric energy provided by an external generator or lithium battery drives the voltage limiting resistor and the control switch; the regulated current flows through the distributor 2 to the high-voltage package and the spark plug 4 to ignite the combustion of the engine.

[0043] The control switch is a manual control switch, which is placed on the console and adjusted by manual control.

[0044] The control switch is a parallel control switch. The temperature sensor 25 detects the engine temperature and transmits it to the signal identification transmitter. The signal identification transmitter then transmits the judgment result to the parallel control switch, thereby realizing automatic control.

[0045] As shown in FIG5 , the components within the dotted box and the temperature sensor 25 together constitute a high-temperature protection circuit for summer traffic jam conditions. The principle is that when the engine is high in temperature, the ignition voltage will be reduced, and the high temperature will disappear. Normally, because there is no resistance in this path of the control switch, the voltage-limiting resistor does not work. When the temperature is high, the control switch is closed, and the current can only flow through the voltage-limiting resistor.

[0046] During specific use, the ignition coil 1 is powered by an external generator or lithium battery, and the ignition coil 1 supplies power to the distributor 2 through a high-voltage line. Through the distribution of the distributor 2, multiple groups of spark plugs 4 can be controlled to circulate electricity and ignite in turn, thereby controlling the combustion of combustible gases inside multiple cylinders.

[0047] Normally, the circuit flows through the path where the control switch is located. This loop has no resistance and the voltage-limiting resistor does not work. Therefore, the current in the entire circuit is relatively large. To avoid high temperatures, when the engine temperature is too high, the circuit needs to be switched to the path where the voltage-limiting resistor is located. At this time, the current in the circuit is relatively small.

[0048] When current passes through the distributor 2, the rotation of the rotary terminal 14 can control the sickle-shaped bent portion 20 and each group of ignition contacts 11 to cyclically contact, thereby providing a pulse current to the spark plug 4 for ignition.

[0049] When the ignition advance angle needs to be changed, it is only necessary to manually rotate the winding column 16. By changing the winding amount of the tensioning belt 17, the free state position of the sickle-shaped bend portion 20 can be adjusted, thereby changing the timing of the contact between the sickle-shaped bend portion 20 and the ignition contact 11 while keeping the rotation control of the drive motor 13 unchanged, thereby adjusting and controlling the ignition advance angle.

[0050] The control switch connected in parallel with the hydraulic resistor in this solution is divided into two types: manual control switch and automatic control switch. The manual control switch is placed on the console and is controlled by manual adjustment.

[0051] The automatic control switch collects engine temperature data through the temperature sensor 25 and then transmits the data to the ECU 26 , which controls the ignition device 22 to ignite.

[0052] Lithium batteries have the ability to charge to 14.6 volts, but the generator voltage is only 14.1 volts to 14.2 volts, so during use it can only be maintained at 13.9 volts or 14 volts. The surplus capacity prevents battery degradation and maintains the ignition voltage.

[0053] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0054] The present invention and its embodiments are described above. This description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present invention, designs structures and embodiments similar to this technical solution without inventiveness, they shall fall within the scope of protection of the present invention.
