Detailed Implementation

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figure 1-5 As shown, the lightweight and compact ignition coil includes:

[0028] The lightweight outer shell 1 adopts a composite structure of a topology-optimized hollow aluminum alloy frame and a carbon fiber composite material layer. Its bottom surface is fixedly connected to an active cooling shell 2, and its top surface is provided with a plug-in seat 5.

[0029] The layered electromagnetic assembly is nested inside the lightweight housing 1 and consists of a primary coil frame and a secondary coil frame, with a dynamically adjustable spacing structure formed between them by a set of elastic conductive pads.

[0030] The transition post 6 is inserted into the insertion seat 5, and its top end is connected to the inclined tube 8 through the bearing rotating part 7. The inner surface of the bottom of the inclined tube 8 is provided with internal gear teeth 15 at equal intervals.

[0031] The drive mechanism includes a motor 12 fixed to the top of the transition column 6 and a drive gear 13 connected to the output shaft of the motor. The drive gear 13 meshes with the inner gear teeth 15 at the bottom of the inclined tube 8 for transmission.

[0032] In this embodiment, the active cooling housing 2 is embedded with a serpentine cooling copper tube 201. Each end of the cooling copper tube 201 is equipped with a quick-connect fitting 10 with a self-sealing valve. The quick-connect fitting 10 is configured to connect to an external coolant circulation device. The serpentine cooling copper tube 201 embedded in the active cooling housing 2 is connected to the external coolant circulation device via the quick-connect fitting 10. Its function is to utilize the circulating flow of coolant to remove the heat generated during the operation of the ignition coil, achieving active cooling, ensuring the ignition coil operates in a stable temperature environment, and improving its performance and service life.

[0033] In this embodiment, the bearing rotating component 7 includes a double-direction angular contact ball bearing, the outer ring of which is interference-fitted with the inclined tube 8, and the inner ring of which is fixedly connected to the top of the transition column 6 via a conical locking structure. This design allows the inclined tube 8 to rotate flexibly around the top of the transition column 6 while ensuring connection stability, thus enabling the ignition head 9 to adjust its angle.

[0034] In this embodiment, the lightweight housing 1 integrates a mounting base 3 and a high-voltage wiring port 4 on its side wall. The mounting base 3 has a shock-absorbing rubber layer and a bolt through-hole array, and the high-voltage wiring port 4 has an anti-arc ceramic ring embedded inside. The shock-absorbing rubber layer can reduce the impact of vibration on the ignition coil and improve its stability; the anti-arc ceramic ring can prevent arcing at the high-voltage wiring port 4 and improve safety during use.

[0035] In this embodiment, an ignition head 9 is detachably connected to the top of the inclined tube 8, and a wiring channel tube 14 extends from its bottom. This wiring channel tube 14 and the inner cavity of the transition column 6 form a cable routing channel, and an electromagnetic shielding layer is laid on the inner wall of the channel. The detachable ignition head 9 facilitates replacement and maintenance; the electromagnetic shielding layer prevents electromagnetic interference and ensures the stability of the cable transmission signal.

[0036] In this embodiment, the elastic conductive pad assembly comprises alternating layers of beryllium copper corrugated pads and polyimide insulating pads. A limiting boss structure to prevent axial displacement is provided on the outer periphery of the pad assembly. The beryllium copper corrugated pads possess good conductivity and elasticity, enabling dynamic spacing adjustment; the polyimide insulating pads provide insulation; and the limiting boss structure prevents axial displacement of the pad assembly, ensuring structural stability.

[0037] Working principle: When the ignition system needs to ignite, the layered electromagnetic components start working. The primary coil frame and the secondary coil frame form a dynamic spacing adjustment structure through a group of elastic conductive pads to optimize electromagnetic performance. During operation, the ignition coil generates heat. The serpentine cooling copper pipe 201 inside the active cooling housing 2 circulates coolant through an external coolant circulation device to remove heat, achieving active cooling.

[0038] When the motor 12 in the drive mechanism starts, it drives the drive gear 13 to rotate. The drive gear 13 meshes with the inner gear 15 at the bottom of the tilt tube 8, causing the tilt tube 8 to rotate around the top of the transition column 6 through the bearing rotating part 7, thereby realizing the angle adjustment of the ignition head 9.

[0039] Current is input to the ignition coil through the high-voltage terminal 4. After electromagnetic conversion by the layered electromagnetic components, it generates an electric spark through the ignition head 9 to achieve the ignition function.

[0040] The circuits, electronic components, and control modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the software and methods.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
