Description

Technical Field

[0001] The utility model belongs to the technical field of ignition coils, and in particular relates to an anti-interference stable block ignition coil. Background Art

[0002] In modern automotive ignition systems, a block ignition coil (also called a direct ignition coil or COP, Coil-On-Plug) is mounted directly on the spark plug to provide the necessary high voltage electricity to ignite the fuel gas. This configuration simplifies the design of the ignition system, improves the efficiency of energy transmission, and reduces energy loss. However, this design also faces several challenges, especially in terms of anti-interference ability and stability.

[0003] First, since block ignition coils are directly installed near the combustion chamber of the engine, they are exposed to extremely high temperatures and harsh working environments. Existing block ignition coils usually do not have integrated cooling functions. Working under high temperature conditions for a long time will cause the performance of internal electronic components to degrade or even be damaged, thus affecting the stability and life of the entire ignition system. Secondly, the current block ignition coil design lacks an effective electromagnetic interference (EMI) shielding device in the ignition head part. The complexity of automotive electronic systems continues to increase, and electromagnetic interference has become an increasingly serious problem. The ignition coil generates high voltage electricity when working. If there is no effective shielding, these high-voltage electrical signals are likely to interfere with surrounding electronic equipment and affect the normal operation of the car.

[0004] In order to solve the above problems, the present application proposes an anti-interference stable block ignition coil. Utility Model Content

[0025] In this embodiment: Under normal circumstances, since the block ignition coils are directly installed near the combustion chamber of the engine, they are exposed to extremely high temperatures and harsh working environments. Existing block ignition coils usually do not have an integrated cooling function. Working under high temperature conditions for a long time will cause the performance of internal electronic components to degrade or even be damaged, thereby affecting the stability and life of the entire ignition system. Secondly, the current block ignition coil design lacks an effective electromagnetic interference EMI shielding device in the ignition head 2 part. The complexity of automotive electronic systems continues to increase, and electromagnetic interference has become an increasingly serious problem. The ignition coil will generate high voltage electricity when working. If there is no effective shielding, these high-voltage electrical signals are likely to interfere with surrounding electronic equipment and affect the normal operation of the car. Then, by adding an ignition coil stabilization anti-interference mechanism 3, the anti-interference ability of the ignition coil can be improved, and at the same time, the ignition head 2 of the ignition coil can be cooled to effectively increase the service life.
