Description

Technical Field

[0001] The invention relates to the technical field of automobile electronics and ignition systems, and in particular to an integrated ignition device. Background Art

[0002] In the prior art, a multi-tooth distributor, as disclosed in the patent with publication number CN220302246U, is a common ignition system component, which is mainly used to distribute the ignition signal to each cylinder of the engine in sequence to achieve multi-point sequential ignition. This type of distributor usually includes a rotor with multiple teeth, which rotates with the crankshaft of the engine and generates an ignition signal by contacting with fixed contacts or sensors. Since the position and shape of each tooth are precisely designed, when the rotor rotates, it contacts different contacts or sensors in sequence, thereby triggering the corresponding ignition operation.

[0003] However, there are some inherent defects in the multi-tooth distributor. First, since it contacts the contacts in sequence by rotating, the accuracy and stability of the rotor must be guaranteed to avoid ignition failures caused by uneven rotation or contact wear. In addition, this design also requires an additional mechanical transmission device to drive the rotor to rotate, which increases the complexity and maintenance cost of the system. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides an integrated ignition device, which solves the problems raised by the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: an integrated ignition device, including an upper shell and a lower cover body fixedly connected by bolts, wherein a plurality of ignition modules are integrated inside the upper shell, and the plurality of ignition modules are distributed in a ring shape inside the upper shell.

[0006] Furthermore, a plurality of external through holes are formed through the top of the upper shell body, and the plurality of external through holes are distributed in a circumference on the top of the upper shell body, and a plurality of bolt holes are arranged around the bottom of the upper shell body.

[0007] Furthermore, a mounting foot is connected to the bottom end of the lower cover body, and the mounting foot is a "π"-shaped structure.

[0008] Furthermore, the ignition module includes an iron core, a winding coil is arranged inside the iron core, the upper part of the winding coil is connected to a high-voltage electrode column, and the lower part of the winding coil is connected to a terminal.

[0009] Furthermore, the top end of the high-voltage electrode column extends to the upper part of the upper shell through the extension through hole and is connected to a wiring terminal, and a wiring groove with an annular structure is provided on the top of the wiring terminal.

[0010] Furthermore, the bottom ends of the terminals are respectively connected to a positive electrode and a negative electrode.

[0011] Furthermore, two fan-shaped winding cavities are symmetrically provided inside the iron core, a winding column is formed between the two winding cavities, and the winding coil is wound around the outside of the winding column.

[0012] Furthermore, the inner side surface of the iron core is configured as an arc surface, and the arc surfaces of a plurality of ignition modules together form a circular through-hole structure.

[0013] Furthermore, the lower cover is a component of insulating material, and a positive conductive ring and a negative conductive ring are respectively connected to the top of the lower cover. The positive conductive ring is located on the inner side of the negative conductive ring, and the positive conductive ring and the negative conductive ring are in contact with the positive column and the negative column respectively.

[0014] Furthermore, the sections of the positive conductive ring and the negative conductive ring are connected with main electrode columns, and the bottom ends of the two main electrode columns extend to the bottom of the lower cover body through the through holes reserved inside the lower cover body.

[0015] The present invention provides an integrated ignition device. Compared with the prior art, it has the following beneficial effects: 1. This integrated ignition device abandons the traditional rotary contact distributor design and integrates several ignition modules inside the upper shell and distributes them in a ring shape. This design not only simplifies the structure of the ignition system, reduces manufacturing costs and maintenance difficulties, but also improves ignition efficiency and reliability. Since the ignition module is static and does not require an additional mechanical transmission device to drive it, ignition problems caused by mechanical failures are reduced.

[0016] 2. The integrated ignition device also achieves more precise and efficient ignition control by optimizing the structure and layout of the ignition module. Each ignition module includes key components such as the iron core, winding coil, and high-voltage electrode column, which work together to generate high-voltage electric sparks to ignite combustible materials. Since the ignition module is integrated inside the upper shell, the position and number of ignition points can be more flexibly configured and adjusted to meet the needs of different engines.

[0017] In summary, the integrated ignition device of the present invention has made significant progress in overcoming the defects of the existing multi-tooth distributor. It provides a simpler, more efficient and reliable ignition solution, and provides a new technical option for automobile engines and other equipment that require precise control of ignition timing.

[0018] 3. The integrated ignition device of the present invention significantly reduces the number of internal wires used by adopting the design of positive conductive rings and negative conductive rings, and only requires two main electrode column external wires, thereby simplifying the circuit layout, greatly facilitating subsequent inspection and maintenance work, and improving the overall reliability and maintenance efficiency of the device.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example 1

[0022] See also Figure 1-6 The present invention provides a technical solution: an integrated ignition device, mainly composed of an upper shell 1, a lower cover 2 and a plurality of ignition modules 3. The upper shell 1 and the lower cover 2 are fixedly connected by bolts to form a closed and solid shell, which is used to protect the internal ignition module 3 from interference from the external environment; A plurality of extension through holes 11 are formed through the top of the upper shell 1, and these through holes are distributed in a circumference on the top of the upper shell 1. The main function of the extension through holes 11 is to allow the high-voltage electrode column 33 to pass through and be connected to the external terminal 34; A plurality of bolt holes 12 are arranged around the bottom of the upper shell 1, and these bolt holes are used to be fixedly connected with corresponding holes on the lower cover 2 by bolts, so as to ensure a tight fit between the upper shell 1 and the lower cover 2; The bottom end of the lower cover 2 is connected to a mounting foot 21, which is a "π"-shaped structure. This design not only enhances the stability of the lower cover 2, but also facilitates the installation of the entire ignition device to a designated position; The core component of the ignition module 3 is the iron core 31, and two fan-shaped winding cavities 311 are symmetrically opened inside the iron core 31. A winding post 312 is formed between the two winding cavities 311, and the winding coil 32 is wound around the outside of the winding post 312. The winding coil 32 is a key component for the ignition module 3 to generate high voltage electricity. A high-voltage electrode post 33 is connected to the upper part of the winding coil 32, and the high-voltage electrode post 33 extends to the upper part of the upper shell 1 through the extension through hole 11, and is connected to a terminal 34. A wiring slot 35 of an annular structure is opened on the top of the terminal 34 for connecting to an external power supply or an ignition signal line. Two terminals 36 are connected to the lower part of the winding coil 32, and the bottom ends of the two terminals 36 are respectively connected to a positive pole 37 and a negative pole 38. The positive pole 37 and the negative pole 38 are used to connect with the positive and negative poles of the external power supply to provide the required electrical energy for the winding coil 32. The inner side surface of the iron core 31 is set as an arc surface 313. When a plurality of ignition modules 3 are distributed in a ring shape inside the upper shell 1, these arc surfaces 313 together form a circular through-hole structure. This design not only makes the layout between the ignition modules 3 more compact and reasonable, but also helps to improve the ignition efficiency; When the external power source provides power to the winding coil 32 through the terminal 34 and the terminal post 36, the winding coil 32 generates a strong magnetic field. This strong magnetic field forms a closed magnetic circuit inside the iron core 31 and generates a high-voltage electric spark at the top of the high-voltage electrode column 33. This high-voltage electric spark can be used to ignite combustible materials such as gas or fuel mixture.

[0023] In summary, the integrated ignition device of the present invention has the advantages of compact structure, reasonable design, high ignition efficiency, etc., and is particularly suitable for occasions requiring simultaneous ignition of multiple points. Example 2

[0024] See also Figure 1 , Figure 7On the basis of Example 1, the present invention further proposes an integrated ignition device, specifically, the lower cover 2 is set to an insulating material, and the top of the lower cover 2 is respectively connected with a positive conductive ring 4 and a negative conductive ring 5, the positive conductive ring 4 is located on the inner side of the negative conductive ring 5, and the positive conductive ring 4 and the negative conductive ring 5 are in contact with the positive pole column 37 and the negative pole column 38 respectively, and the sections of the positive conductive ring 4 and the negative conductive ring 5 are both connected with a total electrode column 6, and the bottom ends of the two total electrode columns 6 are extended to the bottom of the lower cover 2 through the through holes reserved inside the lower cover 2; Compared with the device of Example 1, the device of Example 1 requires at least 16 wires to be laid on the positive poles 37 and negative poles 38 of the eight ignition modules 3, while the device of this embodiment can make corresponding contact with each positive pole 37 and negative pole 38 through the arrangement of the positive conductive ring 4 and the negative conductive ring 5. In this way, there is no need to lay wires inside the device, and only the wires need to be connected to the two extended main electrode poles 6, which is convenient for later inspection and maintenance.
