Description

Technical Field

[0001] The utility model relates to an ignition coil on an engine, in particular to an intelligent feedback working state ignition coil. Background Art

[0002] Generally, an ignition coil does not have a feedback signal of the working state, resulting in the vehicle ECU not monitoring whether the ignition coil is in a normal working state. Once one of the ignition coils fails, the vehicle ECU will continuously output signals to the ignition coil without knowing the condition of the ignition coil, causing other ignition coils to continue working. This leads to a decrease in engine power, and the driver does not receive an alarm reminder of the ignition coil, greatly affecting the service life of the engine. At the same time, when the existing ignition coil generates high voltage, there are phenomena such as electric leakage in its structure, greatly affecting the personal safety of the driver. Summary of the Utility Model

[0003] To solve the above problems, the purpose of the utility model is to provide an intelligent feedback working state ignition coil that prevents electric leakage, thereby greatly improving safety and the service life of the engine.

[0004] To achieve the above purpose, the utility model provides the following technical solution: An intelligent feedback working state ignition coil includes a socket and a housing. The socket is installed at the upper end of the housing. An iron core, a primary skeleton, a secondary skeleton, a high-voltage terminal, and a sheath are installed on the housing. Enameled wires are respectively wound around the primary skeleton and the secondary skeleton. An electronic module is also provided in the socket. The enameled wires on the primary skeleton and the secondary skeleton are respectively connected to the electronic module. Its characteristics are as follows: The electronic module includes a circuit board, and a processing chip is configured on the circuit board. A plug is provided on the socket. The plug is provided with a positive electrode pin, a negative electrode pin, a signal input pin, and a signal feedback pin. The positive electrode pin, the negative electrode pin, the signal input pin, and the signal feedback pin are respectively connected to the circuit board. The signal input pin and the signal feedback pin are electrically connected to the vehicle ECU. The positive electrode pin and the negative electrode pin are connected to the positive and negative electrodes of the vehicle battery. Epoxy resin is filled in the socket to seal the opening of the socket.

[0005] The described iron core is placed in the inner hole of the primary skeleton, the primary skeleton is placed in the inner hole of the secondary skeleton, the secondary skeleton is inserted into the inner hole of the housing, the lower end of the housing is snap-connected to the sheath, and it further includes a high-voltage terminal. A high-voltage coil is connected between the primary skeleton and the high-voltage terminal. The high-voltage coil includes a high-voltage insertion piece and a plug column arranged at the upper end of the high-voltage terminal. The high-voltage insertion piece is provided with a mounting hole for the plug column to pass through. The inner wall of the mounting hole is convexly provided with annularly and evenly distributed arc-shaped convex edges, and the arc-shaped convex edges abut against the outer wall of the plug column for clamping the plug column. One side of the high-voltage insertion piece extends out a winding plate, and the side edge of the winding plate is provided with sequentially arranged limiting grooves. The end of the enameled wire on the primary skeleton is wound on the winding plate.

[0006] The sheath and the housing are made of plastic material.

[0007] The beneficial effects of the present utility model are as follows: The signal feedback pin feeds back the state of the ignition coil to the vehicle ECU in the form of a signal through the processing chip on the circuit board. Once the ignition coil is powered off, the vehicle ECU cannot read the working state of the ignition coil, and the vehicle can make an alarm signal. In this way, the vehicle ECU can monitor the working state of the ignition coil in real time through the signal feedback pin, ensuring the reliability of the engine operation and extending the service life of the engine. The epoxy resin filled in the socket, and the insulation properties of the sheath and the housing can effectively improve the anti-electric leakage performance, thus achieving the technical effect of preventing electric leakage, greatly improving safety and the service life of the engine.

The positive pin 12 and the negative pin 13 are connected to the positive and negative poles of the battery. Epoxy resin is filled in the socket 1 to seal the opening of the socket 1. The sheath 7 and the housing 2 are made of plastic material.

[0016] The iron core 3 is placed in the inner hole of the primary skeleton 4. The primary skeleton 4 is placed in the inner hole of the secondary skeleton 5. The secondary skeleton 5 is inserted into the inner hole of the housing 2. The lower end of the housing 2 is snap-connected to the sheath 7. A high-voltage terminal 6 is also included. A high-voltage pack 9 is connected between the primary skeleton 4 and the high-voltage terminal 6.

The insulation of the epoxy resin filled in the socket 1, the sheath 7 and the housing 2 can effectively improve the anti-electric leakage performance, thus achieving the technical effect of preventing electric leakage, greatly improving safety and the service life of the engine.
