Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figure 1-3 This utility model provides an embodiment of an automotive engine ignition coil, comprising a lower housing 1, a fixed cylinder 2 fixedly connected to the inner wall of the lower housing 1, the inner wall of the fixed cylinder 2 slidably connected to the outer side of the bottom of a winding rod 3, an iron core 11 fixedly connected to the middle of the winding rod 3, a primary coil 10 disposed on the outer side of the upper middle part of the winding rod 3, a secondary coil 12 disposed on the outer side of the lower middle part of the winding rod 3, an upper housing 8 fixedly connected to the top of the lower housing 1, the top of the upper housing 8 fixedly connected to the bottom of a sealing cover 13, the middle part of the sealing cover 13 fixedly connected to the outer side of one end of a wire 14, a second mounting plate 16 fixedly connected to one side of the sealing cover 13, a bolt 17 threadedly connected to the middle of the second mounting plate 16, and the bottom outer side of the bolt 17 threadedly connected to the middle of a first mounting plate 15. One side of the first mounting plate 15 is fixedly connected to the top side of the upper housing 8. The bottom of the bolt 17 is threaded with a nut 18. The bottom of the winding rod 3 is fixedly connected with an electrode head 4. During operation, the device can be installed inside the car through the fixing plate 6 and the fixing hole 7. When the wire 14 is energized, the current will enter the secondary coil 12 through the iron core 11 from the primary coil 10, and finally exit from the electrode head 4, thereby completing the ignition process. The bottom of the winding rod 3 is slidably connected to the inner wall of the fixing cylinder 2. The fixing cylinder 2 can be made of ceramic material to achieve the effect of insulation. When installing the winding rod 3, the bottom of the winding rod 3 is inserted into the inside of the fixing cylinder 2. The sealing cover 13 is installed to fix the winding rod 3 inside the device to avoid the winding rod 3 being damaged by the large pressure during assembly.

[0029] There are two first mounting plates 15, which are respectively located on both sides of the middle of the sealing cover 13. There are two second mounting plates 16, which are respectively located on the top of both sides of the upper housing 8. Each of the two first mounting plates 15 and the two second mounting plates 16 has a threaded hole in its middle. There are two bolts 17, which are respectively located on both sides of the sealing cover 13. Nuts 18 are threaded to the bottom of each bolt 17. The bottom of the outer side of the upper housing 8 is fixedly connected to the inner wall of the limiting ring 5. A fixing plate 6 is fixedly connected to the outer side of the limiting ring 5. A fixing hole 7 is provided in the middle of the fixing plate 6. There are four fixing plates 6, which are evenly distributed on the outer side of the limiting ring 5. Each of the four fixing plates 6 has a fixing hole 7 in its middle. Several heat dissipation holes 9 are provided in the lower middle part of the upper housing 8. The top of the upper housing 8 is provided with a sealing groove 19, and the inner wall of the sealing groove 19 is provided with a sealing ring 20. The top of the sealing ring 20 is fixedly connected to the bottom surface of the sealing cover 13. Through the cooperation between the limiting ring 5 and the fixing plate 6, it can play a role in limiting the position when installing this device, which can assist the operator in installing or assembling it, making the operation of the operator more convenient. Furthermore, by rotating the bolt 17 and the nut 18, the distance between the first mounting plate 15 and the second mounting plate 16 can be reduced, thereby reducing the distance between the upper housing 8 and the sealing cover 13. This allows the sealing ring 20 to be squeezed into the sealing groove 19, which can prevent current from shooting out from the top and causing a short circuit in the device, thus improving the safety of use. In addition, the outer side of the upper housing 8 is provided with several heat dissipation holes 9, which can dissipate the heat generated during its operation, further increasing the safety of use.

[0030] Working principle: During operation, the device can be installed inside the car through the fixing plate 6 and fixing hole 7. When the wire 14 is energized, the current will enter the secondary coil 12 through the iron core 11 from the primary coil 10, and finally exit from the electrode head 4, thereby completing the ignition process. The bottom of the winding rod 3 is slidably connected to the inner wall of the fixing cylinder 2. The fixing cylinder 2 can be made of ceramic material to achieve the effect of insulation. When installing the winding rod 3, the bottom of the winding rod 3 is inserted into the inside of the fixing cylinder 2. The sealing cover 13 is installed to fix the winding rod 3 inside the device to avoid the winding rod 3 being damaged by the large pressure during assembly. The cooperation between the limiting ring 5 and the fixing plate 6 can limit the position when installing this device, which can assist the staff in installing or assembling it, making the operation more convenient. By rotating the bolt 17 and nut 18, the distance between the first mounting plate 15 and the second mounting plate 16 can be reduced, thereby reducing the distance between the upper housing 8 and the sealing cover 13. This allows the sealing ring 20 to be squeezed into the sealing groove 19, which can prevent current from shooting out from the top and causing a short circuit in the device, thus improving the safety of use. In addition, several heat dissipation holes 9 are provided on the outer side of the upper housing 8 to dissipate the heat generated during operation, increasing the safety of use.
