Description

Technical Field

[0001] This invention relates to the field of automotive ignition coil technology, specifically to an integrated automotive ignition coil. Background Technology

[0002] Integrated automotive ignition coils combine multiple independent ignition coils into a single housing to form an integrated ignition device. This can effectively improve installation speed and maintenance efficiency. However, during use, it is inconvenient to control the stability of the integrated automotive ignition coil assembly and it is difficult to quickly replace individual ignition coils when they are damaged.

[0003] To overcome the aforementioned shortcomings, existing technology (Chinese patent application No. CN202211531040.X, application date 2022-12-02) uses a pre-formed tin-plated copper wire fixed on a primary connection board to replace the PCB circuitry for primary circuit connection. This process is simple, eliminates the need for two double-sided PCB boards, significantly reduces product cost, simplifies assembly, and improves both efficiency and quality. Another existing technology (application No. CN20161078778) also addresses this issue. 8.4 (Chinese patent application filed on August 31, 2016) An integrated ignition coil includes a large, rectangular outer shell. Multiple mounting holes are vertically arranged on the large outer shell. A single pen-type ignition coil unit is inserted into each mounting hole. The large outer shell has an internal mounting cavity. A circuit board unit is disposed within the mounting cavity above each pen-type ignition coil unit. Each pen-type ignition coil unit is electrically connected to the circuit board unit. A low-voltage head is disposed on one side of the mounting cavity, and the low-voltage head is electrically connected to the circuit board unit. ; and existing technology (Chinese patent application CN202321303289.5, filed on 2023-05-23) describes an integrated automotive ignition coil. This coil uses an auxiliary sealing ring, a rubber gasket, and an O-ring on the outer circumference of the sealing ring to form multiple seals. Even if one seal fails, another seal can still prevent arc leakage, effectively ensuring the sealing performance of the automotive ignition coil after it is installed in the insertion hole on the engine. If the rubber gasket weakens due to aging, the pressure spring can use its own elasticity to automatically compress the compression ring. The extrusion groove wall is compressed, causing the rubber gasket to expand and deform, further adhering to the inner wall of the insertion hole and the outer wall of the ignition body. This ensures the sealing effect of the rubber gasket, minimizes the possibility of arc leakage, and guarantees ignition performance. The protective sleeve separates the sealing ring from the ignition body. Although existing technologies allow for integrated assembly, the entire unit needs to be replaced if a single ignition coil is damaged, resulting in equipment waste. Furthermore, excessive heat is easily generated during use, affecting the stability of control during operation and reducing service life.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-8 The present invention provides a technical solution: an integrated automotive ignition coil, which is provided with a connector 2 that is rotatably connected to the inner surface of the ignition coil housing 1.

[0022] Example 1: As Figures 1-8 The present invention provides the following technical solution: a one-piece automotive ignition coil, comprising: a control circuit 3, installed on the right side of the outer surface of a connector 1 2, and a connector 2 7 connected to the connector 1 2 via an elastic tilting mechanism, and an ignition coil individual 8 mounted on the outer surface of the connector 2 7, while the ignition coil housing 1 holds the ignition coil individual 8 via a pressing and engaging mechanism, and the ignition coil housing 1 is connected to a gear 9 via a limiting and engaging mechanism, and a heat dissipation fin 24 is connected to the upper surface of the ignition coil housing 1.

[0023] During use, connector 12 is evenly assembled on the inner surface of the ignition coil housing 1. The inclined setting of connector 12 facilitates the docking connection of connector 22 to the ignition coil individual 8, improving the ease of connection. The ignition coil individual 8 is nested inside the ignition coil housing 1. The limiting engagement mechanism controlled by gear 9 improves the engagement stability and prevents the ignition coil individual 8 from loosening due to the rotation of gear 9. The limiting engagement structure connected by gear 9 improves the stability of gear 9 in use. In conjunction with the cooperation of heat dissipation fins 24 and cooling fan 26, the service life of ignition coil individual 8 is improved.

[0024] Example 2: Figures 1-7 The technical solution shown, based on Embodiment 1, further discloses the stability of the docking of individual ignition coils 8, improves the ease of replacement of the coils within the ignition coil housing 1, prevents them from falling off, and increases their stability in use. This solves the problem of wasting equipment when a single ignition coil is damaged and requires complete replacement. The specific details are as follows: The elastic tilting mechanism also includes a side plate 4 mounted on the right side of the outer surface of connector 1 2, and a lifting spring 5 elastically connects the side plate 4 to the ignition coil housing 1. Sealing plates 6 are mounted on both the upper and lower sides of the outer surface of connector 1 2, and connector 2 7 is nested within the inner surface of connector 1 2; Figure 3 , Figure 4 and Figure 5As shown, connector 1 2 forms an elastic rotating structure with the ignition coil housing 1 via side plate 4 and lifting spring 5, and connector 1 2 forms a sealing structure with the ignition coil housing 1 via sealing plate 6. The sealing plate 6 has a corrugated shape when in operation. Simultaneously, connector 1 2 forms a connecting structure with the ignition coil individual 8 via connector 2 7. Figure 3 , Figure 4 and Figure 5 As shown, the compression locking mechanism also includes a gear 9 rotatably connected to the inner surface of the ignition coil housing 1, and a rack 10 meshing with the outer surface of the gear 9. A compression shaft 11 is mounted on the outer surface of the rack 10, and a compression plate 12 is connected to the outer surface of the rack 10. A groove 13 is formed on the inner surface of the compression plate 12, and the compression shaft 11 is slidably connected to the inner surface of the groove 13. A buckle 14 is mounted on the lower surface of the compression plate 12, and the buckle 14 is used to limit and clamp the ignition coil individual 8 to the outer surface. Figure 3 , Figure 4 and Figure 5 As shown, the ignition coil housing 1 and the gear 9 form a rotating structure, and the gear 9 and the rack 10 form a meshing structure. The rack 10, through the extrusion shaft 11 and the slide groove 13, forms a sliding extrusion rotation structure with the extrusion plate 12. Simultaneously, the extrusion plate 12, through the buckle 14, forms a limiting clamping structure with the ignition coil individual 8. Figure 6 and Figure 7 As shown, the limiting engagement mechanism also includes a telescopic column 15 that is telescopically connected to the inner surface of the gear 9. A limiting ring 17 is installed on the upper surface of the telescopic column 15, and a handle 16 is rotatably connected to the top of the limiting ring 17, thus limiting and engaging the limiting ring 17 inside the ignition coil housing 1. Simultaneously, a slide bar 18 is installed on the outer surface of the telescopic column 15, and the telescopic column 15 slides on the inner surface of the gear 9 via the slide bar 18. A base plate 19 is installed on the lower surface of the telescopic column 15, and a return spring 20 is connected between the upper surface of the base plate 19 and the top of the inner surface of the gear 9. Figure 6 and Figure 7 As shown, gear 9 forms a limiting sliding structure with telescopic column 15 via slide bar 18, and telescopic column 15 forms an elastic reset structure with gear 9 via base plate 19 and reset spring 20; Figure 6 and Figure 7 As shown, the telescopic column 15 and the handle 16 form a rotating structure, and the telescopic column 15 and the lower surface of the limiting ring 17 are embedded and installed, and the limiting ring 17 and the ignition coil housing 1 form an embedded engaging structure.

[0025] When the ignition coil unit 8 is damaged and needs to be replaced, the old ignition coil unit 8 is removed, and the connector 2 7 for the new ignition coil unit 8 is stably nested inside the tilted connector 2. After docking, the ignition coil unit 8 is rotated, and the connector 2 is simultaneously rotated within the ignition coil housing 1. This controls the side plate 4 of the connector 2 to compress and contract the lifting spring 5 connected to it, and the sealing plate 6 of the connector 2 will gradually become corrugated, improving the sealing performance of the connector 2 in both docked and non-docked situations, and enhancing the safety of the control circuit 3 installed in the connector 2 during operation. After the ignition coil unit 8 is rotated, the manual handle 16 is rotated on the limit ring 17, causing the telescopic column 15 installed on the limit ring 17 to slide within the gear 9. This compresses the return spring 20 between the base plate 19 of the telescopic column 15 and the gear 9, thus disengaging the limit ring 17 from its limited position. The handle 16 is rotated, and the telescopic column 15, which is installed in conjunction with the limiting ring 17, is connected to the telescopic column 15. The sliding strip 18 installed on the outside of the telescopic column 15 and the gear 9 are limited to slide, which drives the gear 9 to rotate inside the ignition coil housing 1. The rack 10 connected to the gear 9 is controlled to translate on the inner surface of the ignition coil housing 1. The translation of the rack 10 controls the extrusion shaft 11 installed at its end to slide in the slide groove 13 opened in the extrusion plate 12. The extrusion plate 12 is adjusted to limit the rotation inside the ignition coil housing 1. The buckle 14 installed on the lower side of the extrusion plate 12 clamps the ignition coil individual 8 and forms a limiting engagement to prevent the ignition coil individual 8 from shaking or falling off. After the clamping and limiting are completed, the handle 16 can be released to lock the limiting ring 17 inside the ignition coil housing 1. This prevents the locking gear 9 from rotating on its own, improves the stability of the ignition coil individual 8 after assembly, avoids the need to replace the whole integrated automotive ignition coil body, and reduces economic losses.

[0026] Example 3: Figure 1 , Figure 2 and Figure 8 The technical solution shown, based on Embodiment 2, further discloses the cooling effect of the integrated automotive ignition coil body during operation, improves cooling stability, and allows for positioning and disassembly, and can be assembled as needed according to usage requirements. This solves the problem of excessive heat generation during use, which affects control stability and reduces service life. The specific details are as follows: A limiting groove 21 is formed on the inner surface of the ignition coil housing 1, and a main connector 22 is installed on the right side of the outer surface of the ignition coil housing 1. A limiting strip 23 is slidably nested on the inner surface of the limiting groove 21, and a heat dissipation fin 24 is installed on the upper surface of the limiting strip 23. A cover plate 25 is connected to the upper side of the outer surface of the heat dissipation fin 24, and a cooling fan 26 is installed in the middle section of the inner surface of the cover plate 25. Figure 1 , Figure 2 and Figure 8 As shown, the ignition coil housing 1 and the main connector 22 form an integrated structure, and the ignition coil housing 1 forms a limiting embedded structure with the heat dissipation ratchet 24 through the limiting groove 21 and the limiting strip 23, and the heat dissipation ratchet 24 forms a heat dissipation and ventilation structure with the heat dissipation fan 26 and the cover plate 25.

[0027] In use, the heat dissipation fins 24, which are installed on the limiting groove 21 of the ignition coil housing 1, are assembled with the limiting strip 23. The heat dissipation fins 24 are stably attached to the outer surface of the ignition coil housing 1 for stable heat conduction. For the cover plate 25 used after the ignition coil housing 1 is installed, a cooling fan 26 is assembled in the middle section of the cover plate 25. The cooling fan 26 contacts the upper end of the heat dissipation fins 24, which can effectively deliver cold air to the groove of the heat dissipation fins 24 and disperse it at both ends, thereby improving the heat dissipation effect and speed, increasing the life of the ignition coil housing 1 and the connected ignition coil individual 8. The control circuit 3, which is independently connected to the ignition coil individual 8, will be connected to the main connector 22 to improve the overall stability of the circuit connection.

[0029] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
