Description

Technical Field

[0001] The utility model relates to the technical field of ignition coils, in particular to a heat-resistant, voltage-resistant and high-conversion motorcycle ignition coil. Background Technique

[0002] An ignition coil is a tool used to boost the ignition of a motorcycle. It converts low voltage into high voltage through two sets of coils with different directions, and then achieves ignition to start the motorcycle. Therefore, most ignition coils need to have good compressive resistance.

[0003] Under normal circumstances, the high voltage and high current borne by the ignition coil will generate a large amount of heat energy. However, generally, an insulating wire is usually connected below the ignition coil, and the material of the insulating wire generally has a limited temperature tolerance. The fire resistance of the overall ignition coil is determined by the material with the lowest melting point of the surface material, and the melting point of the insulating material is relatively low. Therefore, the insulating wire of the ignition coil is prone to being melted by high temperature, resulting in the peeling off of the outer skin and then exposing the wire.

[0004] At the same time, near the ignition of the motorcycle, since the ignition coil is close to the fuel tank and there is no corresponding cooling device near the insulating wire, and a large amount of heat is easily released under high voltage, the insulating wire that cannot be cooled is difficult to withstand high voltage and high temperature.

[0005] In view of the above situation, we propose a heat-resistant, voltage-resistant and high-conversion motorcycle ignition coil. Content of the Utility Model

[0006] The purpose of the utility model is to solve the defects existing in the prior art, and to propose a heat-resistant, voltage-resistant and high-conversion motorcycle ignition coil.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] A heat-resistant, voltage-resistant and high-conversion motorcycle ignition coil, including an ignition coil main body. The bottom of the ignition coil main body is fixedly connected with an insulating wire. The tail end of the insulating wire is fixedly connected with a lower end interface. The upper part of the ignition coil main body is fixedly connected with a connection interface. The outer surface of the upper part of the ignition coil main body is fixedly connected with a boss. The inner wall of the boss is movably clamped with a connection plug. The bottom of the connection plug is slidably connected with a connection sleeve. A spring is fixedly connected to the inner wall of the connection sleeve. One end of the spring away from the inner wall of the connection sleeve is fixedly connected to the lower end of the connection plug.

[0009] There are two sets of the connecting sleeves. A connecting plate is fixedly connected to the bottom ends of the two sets of connecting sleeves. On the side of the connecting plate away from the ignition coil body, a heat dissipation fan is fixedly connected through a bracket. An output pipe is fixedly connected to the side of the heat dissipation fan away from the connecting pipe.

[0010] One end of the connecting pipe away from the heat dissipation fan is fixedly connected to a spiral air duct. The end of the output of the spiral air duct is fixedly connected to an air exchange pipe. A protective cylinder is sleeved on the outer surface of the insulating wire, and heat dissipation holes are penetrated and opened inside the protective cylinder.

[0011] On both sides of the connection interface, there are positioning plates fixedly connected to the top of the ignition coil body. A fixing rod is fixedly connected to the inner wall between the positioning plates. On one side of the fixing rod, there is a bidirectional lead screw rotatably connected to the inner wall of the positioning plate. A fixing plate is threadedly connected through the outer surface of the bidirectional lead screw, and one end of the fixing plate away from the bidirectional lead screw is slidably connected to the outer surface of the fixing rod.

[0012] The connecting plug rod is slidably connected inside the connecting sleeve.

[0013] The spiral air duct is wound around the outer surface of the insulating wire.

[0014] The air exchange pipe is connected to the outside, and the output pipe is connected to the outside.

[0015] One end of the bidirectional lead screw penetrates through the positioning plate, and a handle is fixedly connected to the outer surface of the top of the end of the bidirectional lead screw penetrating through the positioning plate.

[0016] A heat-resistant, pressure-resistant and high-conversion motorcycle ignition coil proposed by the present utility model has the beneficial effects that: when the ignition coil is in use, the user can turn on the heat dissipation fan, so that the external air enters the air exchange pipe, enters the connecting pipe from the inside of the air exchange pipe, and then enters the spiral air duct. The spiral air duct can extend the contact time with the insulating wire, making its heat dissipation effect better. At the same time, inside the motorcycle, since the insulating wire is close to structures such as the fuel tank, the user extends the air exchange pipe to the outside, so that the temperature of the absorbed incoming air is lower than the temperature inside the fuel tank, and can quickly cool the insulating wire, making it not easy to melt under high temperature and high pressure.
