Abstract
Description
Technical Field
[0001] This utility model relates to the field of pen-type ignition coil technology, specifically a pen-type ignition coil shielding shell. Background Technology
[0002] The pen-type ignition coil is a core component of the modern automotive ignition system. It adopts an integrated design, combining the ignition coil with the high-voltage output terminal and directly mounting it on the top of the spark plug, eliminating the traditional high-voltage wire. It is a typical product of the development of automotive electronics and integration. The pen-type ignition coil shield is an auxiliary component that protects the ignition coil and enhances its working stability. Through the dual functions of mechanical fixation and electromagnetic shielding, it ensures that the ignition coil operates reliably in the complex environment of the engine.
[0003] A novel pen-type ignition coil shielding shell, disclosed in publication number CN215299043U, uses a rigid structure limiting cavity for positioning and a secure fit with the coil housing. This ensures that the ignition coil will not loosen during disassembly and assembly, avoiding inconvenience for disassembly, assembly, and secondary use.
[0004] This new pen-type ignition coil shielding shell uses a positioning boss and a long slot to fix the shielding shell to the outside of the pen-type ignition coil. However, during the installation or disassembly of this device, it relies entirely on squeezing to allow the positioning boss to be inserted into the long slot. The positioning boss is easily damaged due to frequent friction, making the shielding shell unstable when fixed to the outside of the pen-type ignition coil. Therefore, it needs to be improved. Utility Model Content
[0005] The purpose of this invention is to provide a pen-type ignition coil shielding shell to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a pen-type ignition coil shielding shell, including an automobile engine housing, a shielding shell body inserted inside the automobile engine housing, a pen-type ignition coil body inserted inside the shielding shell body, an installation mechanism provided around the shielding shell body, and a limit mechanism provided at the bottom of the outer periphery of the shielding shell body.
[0007] The installation mechanism includes a hollow frame, which is fixedly connected to the left and right sides of the shielding shell body. A fixing rod is fixedly connected to the inner side of the hollow frame. A sliding plate is slidably connected to the outer side of the fixing rod. A connecting rod is fixedly connected to the outer side of the sliding plate. A limit plate is rotatably connected to the outer side of the connecting rod. The limit plate is slidably connected to the inner side of the hollow frame. A pull plate is fixedly connected to the outer side of the limit plate. A spring is sleeved around the outer side of the connecting rod. An inclined plate is fixedly connected to the inner side of the pull plate.
[0008] Preferably, the outer side of the spring is fixedly connected to the inner side of the hollow frame, and the inner side of the spring is fixedly connected to the outer side of the pull plate. When the operator releases the force applied to the pull plate, the elastic force of the spring causes the spring to push the sliding plate to move the tilting plate, so that the tilting plate is inserted into the pen-type ignition coil body and limits the shielding shell body.
[0009] Preferably, the pen-type ignition coil body has an insertion hole inside that corresponds to the position of the tilting plate, and the tilting plate is inserted into the inside of the insertion hole. Through the insertion hole, the tilting plate can be inserted into the pen-type ignition coil body to limit the position of the shielding shell body.
[0010] Preferably, the hollow frame has a groove on its inner side that corresponds to the movement trajectory of the sliding plate, and the sliding plate is slidably connected to the inside of the groove. The groove allows the sliding plate to slide inside the hollow frame, making the sliding plate more stable during movement.
[0011] Preferably, the limiting mechanism includes a fixed plate, which is fixedly connected to the periphery of the shielding shell body. A plug rod is fixedly connected to the bottom of the fixed plate, and a bolt is threadedly connected to the inside of the pen-type ignition coil body.
[0012] Preferably, the inside of the car engine housing is provided with a fixing hole corresponding to the position of the insertion rod, and the insertion rod is inserted into the inside of the fixing hole. Through the fixing hole, the insertion rod can be inserted into the inside of the car engine housing to limit the position of the shielding shell body.
[0013] Preferably, the inside of the car engine housing is provided with a threaded hole corresponding to the position of the bolt, and the bolt is threaded into the inside of the threaded hole. Through the threaded hole, the bolt can be threaded into the top of the car engine housing, so that the pen-type ignition coil body can be fixed to the top of the car engine housing.
[0014] Compared with the prior art, this utility model provides a pen-type ignition coil shielding shell, which has the following beneficial effects:
[0015] 1. In the installation mechanism of this pen-type ignition coil shield, the spring pushes the sliding plate, connecting rod and limiting plate together through elastic force, so that the inclined plate is tightly inserted into the insertion hole of the pen-type ignition coil body to form radial fixation. When disassembling, simply pull the pull plate to drive the inclined plate out of the insertion hole, release the radial constraint on the ignition coil, and with the loosening of the bolts, the shield and pen-type ignition coil body can be quickly disassembled.
[0016] 2. In the limiting mechanism of this pen-type ignition coil shield, the insert rod cooperates with the fixing hole of the car engine housing, and the threaded connection of the bolt allows the pen-type ignition coil body to be fixed to the top of the car engine housing, realizing the axial limiting of the shield body and the engine housing. This effectively avoids the loosening and displacement of the shield and ignition coil caused by vibration during vehicle operation, ensuring that the components are firmly installed.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0026] This utility model provides the following technical solution:
[0027] Example 1
[0028] Please see Figure 1-5 This utility model provides a technical solution: a pen-type ignition coil shielding shell, including an automobile engine housing 2, a shielding shell body 1 inserted inside the automobile engine housing 2, a pen-type ignition coil body 3 inserted inside the shielding shell body 1, an installation mechanism 5 arranged around the shielding shell body 1, and a limit mechanism 4 arranged at the bottom of the outer periphery of the shielding shell body 1.
[0029] The installation mechanism 5 includes a hollow frame 54, which is fixedly connected to the left and right sides of the shielding shell body 1. A fixing rod 56 is fixedly connected to the inner side of the hollow frame 54. A sliding plate 57 is slidably connected to the outer side of the fixing rod 56. A connecting rod 51 is fixedly connected to the outer side of the sliding plate 57. A limiting plate 52 is rotatably connected to the outer side of the connecting rod 51. The limiting plate 52 is slidably connected to the inner side of the hollow frame 54. A pull plate 53 is fixedly connected to the outer side of the limiting plate 52. A spring 55 is sleeved around the outer side of the connecting rod 51. An inclined plate 58 is fixedly connected to the inner side of the pull plate 53.
[0030] Furthermore, the outer side of the spring 55 is fixedly connected to the inner side of the hollow frame 54, and the inner side of the spring 55 is fixedly connected to the outer side of the pull plate 53. When the operator releases the force applied to the pull plate 53, the elastic force of the spring 55 causes the spring 55 to push the sliding plate 57 to move the tilting plate 58, so that the tilting plate 58 is inserted into the pen-type ignition coil body 3, thereby limiting the shielding shell body 1.
[0031] Furthermore, the pen-type ignition coil body 3 has an insertion hole inside that corresponds to the position of the tilt plate 58, and the tilt plate 58 is inserted into the inside of the insertion hole. Through the insertion hole, the tilt plate 58 can be inserted into the pen-type ignition coil body 3 to limit the position of the shielding shell body 1.
[0032] Furthermore, a groove corresponding to the movement trajectory of the sliding plate 57 is provided on the inner side of the hollow frame 54, and the sliding plate 57 is slidably connected to the inside of the groove. Through the groove, the sliding plate 57 can slide inside the hollow frame 54, making the sliding plate 57 more stable during movement.
[0033] Example 2
[0034] Please see Figure 1-5 Furthermore, based on Embodiment 1, the limiting mechanism 4 includes a fixed plate 42, which is fixedly connected to the periphery of the shielding shell body 1. A plug rod 43 is fixedly connected to the bottom of the fixed plate 42, and a bolt 41 is threadedly connected inside the pen-type ignition coil body 3.
[0035] Furthermore, the inside of the car engine housing 2 is provided with a fixing hole corresponding to the position of the insert rod 43, and the insert rod 43 is inserted into the inside of the fixing hole. Through the fixing hole, the insert rod 43 can be inserted into the inside of the car engine housing 2 to limit the shielding shell body 1.
[0036] Furthermore, the interior of the car engine housing 2 is provided with a threaded hole corresponding to the position of the bolt 41, and the bolt 41 is threaded into the inside of the threaded hole. Through the threaded hole, the bolt 41 can be threaded into the top of the car engine housing 2, so that the pen-type ignition coil body 3 can be fixed to the top of the car engine housing 2.
[0037] In actual operation, when this device is used, the pen-type ignition coil body 3 is inserted into the outer periphery of the shielding shell body 1, so that the outer wall of the pen-type ignition coil body 3 and the inner wall of the shielding shell body 1 are in contact with each other. The pen-type ignition coil body 3 is pushed downward so that the outer side of the pen-type ignition coil body 3 can press the inclined plate 58, so that the inclined plate 58 can push the sliding plate 57 to press the spring 55. When the pen-type ignition coil body 3 does not press the inclined plate 58, the elastic force of the spring 55 causes the sliding plate 57 to drive the inclined plate 58 to be inserted into the outer side of the pen-type ignition coil body 3, so that the shielding shell body 1 can be installed on the outer side of the pen-type ignition coil body 3.
[0038] After the shielding shell body 1 is installed, insert the shielding shell body 1 and the pen-type ignition coil body 3 into the interior of the car engine housing 2, so that the insert rod 43 can be inserted into the interior of the car engine housing 2. After the pen-type ignition coil body 3 is installed into the interior of the car engine housing 2, rotate the bolt 41 so that the bolt 41 can be threadedly connected to the pen-type ignition coil body 3 and the interior of the car engine housing 2, so that the pen-type ignition coil body 3 is not easy to loosen when the car is driving, making the pen-type ignition coil body 3 more stable.
