Description

Technical Field

[0001] This invention relates to the field of ignition coil technology, and in particular to a high-stability, long-life pen-type ignition coil. Background Technology

[0002] Currently, automotive ignition coils are primarily responsible for converting the low voltage (usually 12 volts) provided by the vehicle battery into a high voltage (usually tens of thousands of volts) to generate a spark that ignites the fuel mixture in the engine cylinders. Ignition coils work through the principle of electromagnetic induction, converting low-voltage electricity into high-voltage electricity to ensure normal engine operation and smooth combustion.

[0003] However, currently, when replacing ignition coils, it is necessary to insert the coil into an ignition slot cut into the engine cylinder surface, and then tighten it from the top with corresponding bolts. During the tightening process, the ignition coil itself lacks a limiting mechanism. Therefore, during the installation process, the operator must continuously support the ignition coil manually while tightening the bolts to prevent tilting or shifting, which would affect the stability of the installation. This not only increases the labor required for installation but also makes it easy for the ignition coil to wobble due to insufficient support, affecting its subsequent stability. Therefore, we propose a high-stability, long-life pen-type ignition coil. Utility Model Content

[0004] The main objective of this invention is to provide a highly stable and long-life pen-type ignition coil, which can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-stability, long-life pen-type ignition coil includes an ignition coil tube, with a wiring connector and a connecting pad installed on both sides of the top of the ignition coil tube. A threaded sleeve is screwed onto the top of the ignition coil tube, and a thread that matches the inner wall of the threaded sleeve is formed on the outer side of the top of the ignition coil tube. A connecting sleeve is movably fitted to the bottom of the outer side of the threaded sleeve, and an installation frame is fixedly sleeved on the outer side of the ignition coil tube.

[0007] The bottom of the connecting sleeve is provided with a pushing mechanism, the inside of the mounting frame is provided with a transmission mechanism, and the bottom of the mounting frame is provided with a clamping mechanism, and the transmission mechanism and the clamping mechanism are connected.

[0008] As an optional solution to the technical solution of this application, the transmission mechanism includes a transmission block, the mounting frame has a movable groove inside, each movable groove has a mounting groove at the bottom center, each mounting groove has a transmission plate movably installed inside, each transmission plate has a transmission block fixedly installed on top, and each movable groove has a reset spring movably installed inside.

[0009] By adopting the above technical solution, under the structural action of the transmission block and the return spring, the pushing block can abut against the transmission block during the downward movement, causing it to move horizontally. Then, combined with the restoring pushing action of the return spring, the transmission block can move horizontally and synchronously after the pushing block moves away from the outside of the transmission block, thereby driving the pressing plate to return to its position, which facilitates the disassembly of the ignition coil.

[0010] As an optional solution to the technical solution of this application, the clamping mechanism includes a clamping plate, a connecting plate is fixedly installed at the bottom of each transmission plate, and the connecting plate slides against the bottom surface of the mounting frame. A support column is fixedly installed laterally at the middle of the bottom of each connecting plate, and a clamping plate is fixedly installed at the top of the side of each support column away from the connecting plate.

[0011] By adopting the above technical solution, under the transmission action of the transmission plate, when the transmission plate moves horizontally as the pushing block abuts against the transmission block, it can drive the pressing plate to move horizontally synchronously.

[0012] As an optional solution to the technical solution of this application, the pushing mechanism includes a pushing block, and the pushing block is fixedly installed at the bottom of the connecting sleeve.

[0013] By adopting the above technical solution, under the structural action of the push block, when the connecting sleeve moves vertically, the push block can move along with it and insert into the movable groove, causing the transmission block to move horizontally.

[0014] As an optional solution to the technical solution of this application, the connecting sleeve is fixedly installed with snap-fit ​​sliders at both ends of the top outer side, the threaded sleeve is provided with a limit groove at the bottom, the connecting sleeve is fixedly installed with a limit post at both ends of the inner side, the ignition wire tube is provided with a guide groove at the top outer side, and the side end of the limit post is slidably inserted into the guide groove.

[0015] By adopting the above technical solution, under the limiting sliding action of the limiting slide groove on the locking slider and the guiding sliding action of the guide slide groove on the limiting post, the threaded sleeve will not arbitrarily drive the connecting sleeve and the push block at its bottom to rotate after the operator turns the threaded sleeve, thereby ensuring the stability of the push block's abutting transmission to the transmission block.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present application discloses a high-stability, high-life pen-type ignition coil. A threaded sleeve is screwed onto the outside of the ignition coil, and a pushing block is located on the outside of the sleeve at the bottom. When the operator screws the threaded sleeve, the connecting sleeve and its bottom pushing block move vertically synchronously on the outside of the ignition coil. Combined with multiple sets of transmission blocks located on the inner wall of the mounting frame, the pushing block, after moving vertically and engaging with the inclined surface of the transmission block, receives a corresponding pushing force as the transmission block continues to move downwards. This allows the pushing block to drive a transmission plate to move horizontally relative to it within the mounting frame. This, in turn, drives a clamping plate connected to the transmission plate to move relative to it on the outside of the ignition coil until the clamping plate engages with the inner wall of the ignition slot inside the engine. This provides a centered, clamping, and limiting effect on the ignition coil, preventing it from wobbling freely within the ignition slot and affecting its installation and use stability. It also reduces the labor required for the operator to manually limit the ignition coil during installation.

[0018] 2. A high-stability, high-life pen-type ignition coil according to the technical solution of this application, by setting a limiting post on the inner side wall of the connecting sleeve, and inserting the limiting post into the guide groove on the outside of the ignition coil tube, and sliding the snap-fit ​​slider located at the top of the connecting sleeve into the limiting groove at the bottom of the threaded sleeve, so that when the operator turns the threaded sleeve, the threaded sleeve will not arbitrarily drive the connecting sleeve and the push block at its bottom to rotate, thereby ensuring the stability of the push block's abutment transmission to the transmission block.

[0023] like Figure 1-3 As shown, this utility model provides a technical solution: a high-stability, high-life pen-type ignition coil, wherein the top of the ignition coil tube 1 is screwed with a threaded sleeve 2, the outer side of the top of the ignition coil tube 1 is provided with a thread that matches the inner side wall of the threaded sleeve 2, the bottom of the outer side of the threaded sleeve 2 is movably fitted with a connecting sleeve 21, the outer side of the ignition coil tube 1 is fixedly fitted with an installation frame 22, and the bottom of the connecting sleeve 21 is fixedly installed with a push block 23, and the number of push blocks 23 is the same as the number of movable slots 3.

[0024] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), the mounting frame 22 has six sets of movable slots 3 inside. Each movable slot 3 has a mounting slot 31 at the bottom center, and the mounting slot 31 and the movable slot 3 are connected. A transmission plate 24 is movably installed inside each mounting slot 31. A transmission block 25 is fixedly installed on the top of each transmission plate 24, and the transmission block 25 is movably set inside the mounting slot 31. A return spring 29 is movably installed inside each movable slot 3, and the two ends of the return spring 29 are movably attached to the outer wall of the transmission plate 24 and the inner wall of the mounting slot 31, respectively.

[0025] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown, a connecting plate 26 is fixedly installed at the bottom of each transmission plate 24, and the connecting plate 26 slides against the bottom surface of the mounting frame 22. A support column 27 is fixedly installed horizontally at the middle of the bottom of each connecting plate 26, and a clamping plate is fixedly installed at the top of the side of each support column 27 away from the connecting plate 26.

[0026] In this technical solution (through Figure 1 , Figure 2 and Figure 3 As shown), both ends of the top outer side of the connecting sleeve 21 are fixedly installed with snap-fit ​​sliders 4. The bottom of the threaded sleeve 2 is provided with a limiting groove 41, and the snap-fit ​​sliders 4 are slidably inserted into the limiting groove 41. The vertical cross-sections of the snap-fit ​​sliders 4 and the limiting groove 41 are both inverted T-shaped.

[0027] In some technical solutions (through Figure 1 , Figure 2 and Figure 3 As shown, limit posts 42 are fixedly installed at both ends of the inner side of the connecting sleeve 21, and a guide groove 43 is opened on the outer side of the top of the ignition cable 1, and the side end of the limit post 42 is slidably inserted into the guide groove 43.

[0028] During operation, when it is necessary to disassemble and replace the ignition cable 1, after removing the original ignition cable 1 from the ignition mounting slot 31 at the top of the engine, take the ignition cable 1 to be replaced and insert it vertically into the ignition mounting slot 31, so that the mounting frame 22 and the ignition cable 1 are inserted into the ignition mounting slot 31 simultaneously. Then, the threaded sleeve 2 is turned, so that the threaded sleeve 2 moves downward outside the ignition cable 1. Combined with the connecting sliding action of the limiting slide groove 41 on the locking slider 4 and the guiding sliding action of the guide slide groove 43 on the limiting post 42, the threaded sleeve 2 can drive the connecting sleeve 21 at its bottom to move vertically along the outside of the ignition cable 1. At the same time, the connecting sleeve 21 will not rotate with the turning of the threaded sleeve 2. After the bottom push block 23 moves down into the movable groove 3 inside the mounting frame 22, the inclined surface of the push block 23 fits against the inclined side surface of the transmission block 25. As the push block 23 moves down, it can provide a horizontal pushing force to the transmission block 25, so that multiple sets of transmission blocks 25 can move synchronously relative to each other. Combined with the connecting transmission action of the transmission plate 24, it can drive the sliding plate and its bottom clamping plate 28 to move synchronously relative to each other until the side of the clamping plate 28 fits against the inner wall of the ignition mounting groove 31. The ignition wire 1 can be stably and centrally placed inside the ignition mounting groove 31. Then, the ignition wire 1 is further connected and reinforced by bolts through the connecting plate 26. Finally, the wiring connector 11 and the car battery terminal are connected by the power cable to complete the replacement of the ignition wire 1.
