Description

Technical Field

[0001] The utility model relates to the technical field of ignition coils, in particular to a high-efficiency ignition coil with a control module. Background Art

[0002] As automobile gasoline engines develop towards high speed, high compression ratio, high power, low fuel consumption and low emissions, traditional ignition devices are no longer suitable for use. The core components of the ignition device are the ignition coil and the switch device. By increasing the energy of the ignition coil, the spark plug can generate sparks with sufficient energy, which is the basic condition for the ignition device to adapt to the operation of modern engines. At present, the ignition coils produced domestically are generally dry ignition coils that require high-voltage wire connection. The dry ignition coils are divided into multi-head dry ignition coils and single-head dry ignition coils. Among them, the multi-head dry ignition coil is mainly used in the ignition system without distributor, which requires the connection of high-voltage wires and has a large energy loss; in addition, the multi-head dry ignition coil is responsible for igniting several cylinders at the same time. As long as one of the coils is damaged, the entire coil will be scrapped, resulting in a great waste of resources. At present, the pencil ignition coil has been widely used, but due to energy and environmental protection reasons, the fuel will be replaced by a mixed gasoline or biofuel, such as gasoline and alcohol ethers mixed in a certain proportion, but the mixed fuel has a lower ignition point than pure gasoline, so the pencil ignition coil is required to provide more energy.

[0003] The utility model patent application document with publication number "CN216554186U" discloses an ignition coil with a control module, including a shell, permanent magnets are arranged at both ends of the shell, an iron core is arranged inside the two permanent magnets, an ignition coil is arranged outside the iron core, a voltage sensor is arranged at the rear end of the ignition coil, a position sensor is arranged at the front end of the ignition coil, an ignition control module is arranged at the lower end of the ignition coil, two mounting plates are arranged at the right end of the shell, and two mounting holes are arranged on each mounting plate. The voltage generated by the ignition coil is sensed by the voltage sensor and its signal is transmitted to the ignition control module. The voltage of the ignition coil is controlled to increase or decrease through the ignition control module, so that the voltage generated by the ignition coil remains stable, the angle measurement of the engine position is sensed through the position sensor and converted into a timing ignition signal and transmitted to the ignition control module, so that the ignition coil generates high voltage electricity to output to the spark plug, thereby improving its practicality.

[0004] The ignition coil with control module disclosed in the above document has the following defects: after long-term use, the strength of the plug interface of this technical solution becomes fragile, resulting in direct force acting on the plug hole during plugging and unplugging, causing damage to the plug hole.

[0005] It can be seen from this that the existing ignition coil with a control module does not have a good protection structure, and it is necessary to improve the existing deficiencies and provide a high-efficiency ignition coil with a control module. Utility Model Content

[0014] The utility model has the following beneficial effects:

[0015] (1) The utility model presses the first anti-slip stripe to squeeze the first spring, and then pulls the inclined block to disassemble the plug hole, thereby avoiding the situation where the strength becomes fragile after long-term use, and then the force directly acts on the plug hole during plugging and unplugging, causing damage to the plug hole.

[0016] (2) The utility model connects the engine to the engine by installing the threaded bushing into the interior of the connecting hole and then installing the external connecting bolt into the interior of the threaded bushing.
