[0027] As Figures 1-3 shown, a motorcycle ignition coil with high safety includes a box body 1 and a box cover 2. The upper surface of the box body 1 is open, and the box cover 2 is installed on the upper surface of the box body 1 through a fastening bolt 3, that is, the box cover 2 and the box body 1 can be disassembled;

[0028] A central block 4 is provided at the center of the inner bottom surface of the box body 1. A circular peripheral plate 41 is provided around the central block 4. A plurality of primary winding magnetic cores 42 and secondary winding magnetic cores 43 arranged in a circumferential shape are provided on the surface of the peripheral plate 41. The primary winding magnetic cores 42 and the secondary winding magnetic cores 43 are aligned up and down. A connecting plate 44 is provided at one end of the primary winding magnetic cores 42 and the secondary winding magnetic cores 43 away from the peripheral plate 41. The connecting plate 44 plays a role in fixing the primary winding magnetic cores 42 and the secondary winding magnetic cores 43, making the structure between the primary winding magnetic cores 42 and the secondary winding magnetic cores 43 relatively stable;

[0029] It further includes a primary wire and a secondary wire. On the upper surface of the box cover 2, a first rubber block 23 and a second rubber block 24 are symmetrically arranged. On the first rubber block 23, two first winding wire holes 231 communicating with the box body 1 are symmetrically arranged. On the second rubber block 24, two second winding wire holes 241 communicating with the box body 1 are symmetrically arranged;

[0030] The primary wire is wound around the primary winding magnetic core 42 through the first winding wire hole 231, and the secondary wire is wound around the secondary winding magnetic core 43 through the second winding wire hole 241.

[0031] On the upper surface of the box body 1, a plurality of screw holes 11 distributed in a surrounding shape are evenly arranged at equal intervals. On the lower surface of the box cover 2, an annular sealing gasket 21 is arranged. On the upper surface of the box cover 2, a plurality of through holes 22 distributed in a surrounding shape are evenly arranged at equal intervals. The through holes 22 penetrate through the sealing gasket 21 and are vertically aligned with the screw holes 11. The fastening bolts 3 pass through the through holes 22 and are threadedly connected in the screw holes 11.

[0032] Both the primary winding magnetic core 42 and the secondary winding magnetic core 43 are perpendicular to the outer peripheral plate 41. There are eight to twelve primary winding magnetic cores 42 and secondary winding magnetic core 43, and the primary winding magnetic core 42 and the secondary winding magnetic core 43 are both distributed in an equally spaced surrounding shape.

[0033] The primary winding magnetic core 42 and the secondary winding magnetic core 43 are symmetrically distributed up and down in the height direction of the outer peripheral plate 41.

[0034] One end of both the primary winding magnetic core 42 and the secondary winding magnetic core 43 away from the outer peripheral plate 41 is perpendicular to the connecting plate 44. The area of the connecting plate 44 is larger than the end areas of the primary winding magnetic core 42 and the secondary winding magnetic core 43.

The primary wire coil and the secondary wire coil are also completely located in the coolant;

[0037] During ignition, a small current passes through the primary wire coil. Through the voltage transformation and amplification effects of the primary winding core 42 and the secondary winding core 43, a large current flows through the secondary wire coil and into the spark plug. Among them, the heat generated by the energization of the primary wire coil and the secondary wire coil can quickly enter the coolant, which can avoid heat accumulation.

[0038] The coolant can enter the fitting position of each turn of the coil, and the coolant can fully exchange heat with the primary wire coil and the secondary wire coil, resulting in a better cooling effect; the primary wire coil and the secondary wire coil have higher safety during the energization process.
