Description

Technical Field

[0001] This utility model relates to the field of ignition coil technology, and in particular to a high-conversion ignition coil for motorcycles. Background Technology

[0002] The motorcycle ignition coil is a key component in the engine ignition system. It is responsible for generating high-voltage current, converting electrical energy into a spark, igniting the air-fuel mixture, and propelling the engine to operate normally. Existing motorcycle ignition coils experience energy loss during conversion, which affects their ignition performance. Therefore, we propose a high-conversion ignition coil for motorcycles. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-conversion ignition coil for motorcycles.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a high-conversion ignition coil for motorcycles, comprising a housing, an upper surface of which is provided with a mounting ring, positive and negative terminals on both sides of the middle part of the upper surface of the mounting ring, an iron core in the middle of the inner bottom surface of the housing, and a plurality of expansion discs uniformly fitted on the outer surface of the upper end of the iron core, the expansion discs being of iron structure and integrally formed with the iron core, a secondary coil fitted on the lower part of the outer surface of the iron core, a primary coil fitted on the outer surface of the secondary coil, and wires at both ends of the primary coil, the other end of which is connected to the positive and negative terminals respectively, and a plurality of resistors connected in parallel on the outer surface of the wires connected to the input end of the primary coil.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] In the application of this technical solution, during the use of motorcycle ignition coils, this ignition coil can reduce coil energy loss while ensuring normal coil energy output. At the same time, it can reduce magnetic field conversion loss while keeping the primary current unchanged, thereby increasing the magnetic field energy conversion output efficiency. This is beneficial for reducing the loss of coil energy in output conversion and thus improving the ignition performance of the ignition coil. Attached Figure Description

[0016] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0017] As attached Figure 1-3 The high-conversion ignition coil for motorcycles shown includes a housing 1 made of aluminum alloy. A mounting plate 2 is located on the lower surface of the housing 1. Several mounting holes 3 are evenly distributed through the upper surface of the mounting plate 2. A mounting ring 4 is located on the upper surface of the housing 1. Positive and negative terminals 5 are located on both sides of the center of the upper surface of the mounting ring 4, including a positive terminal and a negative terminal. An iron core 7 is located in the center of the inner bottom surface of the housing 1. A fixing sleeve 6 is fitted onto the upper part of the outer surface of the iron core 7. The outer surface of the fixing sleeve 6 is flush with the inner surface of the housing 1. The iron core 7 is connected to the outer surface of the upper end and several expansion disks 8 are evenly installed. The expansion disks 8 are all made of iron and are integrally made with the iron core 7. The upper end of the outer surface of the iron core 7 is provided with an adapter 9. The lower part of the outer surface of the iron core 7 is fitted with a secondary coil 10. The outer surface of the secondary coil 10 is fitted with a primary coil 11. Both ends of the primary coil 11 are provided with wires 12. The other end of the wires 12 are connected to the positive and negative terminals 5 respectively. Several resistors 13 are installed in parallel on the outer surface of the wires 12 connected to the input end of the primary coil 11.

[0018] During operation, when the outer casing 1 is made of aluminum alloy, it dissipates heat more easily, thus reducing the rate of temperature rise of the ignition coil. Simultaneously, the aluminum alloy casing has a low resistivity, providing better shielding and anti-interference capabilities. The ignition coil is installed by aligning the mounting plate 2 with the installation position of the motorcycle ignition coil and inserting it into the motorcycle using a locking bolt through the mounting hole 3. At this point, the motorcycle's ignition switch can be turned on. The motorcycle battery will then output current to the positive terminal of the positive and negative terminals 5 located on the upper surface of the outer casing 1. The positive terminal can then transmit current to the primary winding via the wire 12. Inside coil 11, since several resistors 13 are connected in series on wire 12, the resistors 13 connected in series on wire 12 can replace the resistance value of the primary coil 11. In this case, the resistance value of the primary coil 11 itself can be reduced by connecting the additional resistors 13 in series. With the reduction of the resistance value of the primary coil 11 itself, the energy loss of the coil can be effectively reduced. At the same time, when the current passes through the primary coil 11, a strong magnetic field can also be generated in the iron core 7, which is beneficial to reduce the energy loss of the coil while ensuring the normal output of the coil energy.

[0019] When a strong magnetic field is generated in the iron core 7, the cross-sectional area of ​​the iron core 7 can be effectively increased by the several expansion disks 8 set on the outer surface of the upper end of the iron core 7. When the cross-sectional area of ​​the iron core 7 increases, the magnetic permeability of the iron core 7 can be effectively improved. When the magnetic permeability of the iron core 7 increases, the loss of the magnetic field can be reduced while the primary current remains unchanged, thereby increasing the conversion output efficiency of the magnetic field energy. At this time, the magnetic field energy converted and output by the iron core 7 will be transferred to the secondary coil 10. When the magnetic field energy enters the secondary coil 10, the magnetic field will change due to the difference in resistance and capacitance, thereby generating a high voltage current in the secondary coil 10. When the generated current is guided to the igniter, a spark can be generated to ignite the air-fuel mixture of the motorcycle, thereby promoting the operation of the motorcycle engine.

[0020] In summary, this ignition coil helps reduce the energy loss of the output conversion coil, thereby improving the ignition performance of the ignition coil.
