[0027] As Figures 1-3 shown, an integrated motorcycle ignition coil structure includes a main housing 1, a mandrel 2, a first cover 3 and a second cover 4. A side tube 11 is provided above the surface of the main housing 1. The lower end of the main housing 1 is open, and one end of the side tube 11 away from the main housing 1 is open. The inside of the side tube 11 and the main housing 1 is connected;

[0029] The surface of the mandrel 2 is wound with a spiral primary coil 21 from bottom to top, and a spiral secondary coil 22 is arranged on the outer periphery of the surface of the mandrel 2 from bottom to top. The number of secondary coils 22 is more than that of primary coils 21;

[0030] The first cover 3 is threadedly connected to one end of the side tube 11 away from the main housing 1, and the second cover 4 is threadedly connected to the bottom end of the main housing 1. Two connected first connectors 31 are provided on the front and back of the first cover 3, and two connected second connectors 41 are provided on the lower and upper surfaces of the second cover 4.

[0031] Both ends of the primary coil 21 are detachably connected to two first connectors 31 respectively, and both ends of the secondary coil 22 are detachably connected to two second connectors 41 respectively.

[0032] On the inner wall of the main housing 1, multiple layers of support blocks are arranged at equal intervals from bottom to top. Each layer has three to four support blocks, which are arranged at equal intervals around the inner wall of the main housing 1. The secondary coil 22 is installed on the support blocks, and the support blocks play a supporting role for the secondary coil 22.

[0033] The bottom bracket 12 includes a central plate and connecting rods. Four connecting rods are arranged in a surrounding shape and at equal intervals around the central plate. The ends of the connecting rods away from the central plate are fixed on the inner wall of the main housing 1.
