Example 1

As shown in fig. 1 to 7, in an embodiment of the present utility model, there is provided an ignition coil mounting structure including a first bracket 20 and an ignition coil body 30, the first bracket 20 being provided on top of an engine body 10, the ignition coil body 30 being provided on the first bracket 20, the ignition coil body 30 being located above a crankcase of the engine body 10.

The ignition coil mounting structure disclosed in this embodiment is separated from the trigger (not shown in the drawings) by arranging the position of the ignition coil body 30 above the crankcase of the engine body 10, namely, at different positions, so that the problem of signal interference of the ignition coil body 30 to the trigger generated when the ignition coil body 30 and the trigger are integrated together in the conventional structure is eliminated, and the normal operation of the engine is ensured. Meanwhile, the ignition coil body 30 is convenient to install, so that occupation of parts is reduced, and the overall structure is simplified. In addition, the ignition coil body 30 is mounted on the first bracket 20, so that the ignition coil body 30 is convenient to mount and maintain.

In one embodiment, the ignition coil body 30 is provided with two connection seats 31, and the first bracket 20 is provided with two fixing members 40, and each fixing member 40 fixes a corresponding connection seat 31 on the first bracket 20. Specifically, the first bracket 20 is provided with two first through holes 21, the connecting seat 31 is provided with a connecting hole 32, the fixing piece 40 comprises a first bolt 41 and a nut 42, and the first bolt 41 sequentially passes through the connecting hole 32 and the first through holes 21 and then is matched with the nut 42.

Two connecting seats 31 are respectively arranged at two ends of the ignition coil body 30, connecting holes 32 with a waist-shaped hole structure are formed in the connecting seats 31, when the ignition coil body 30 is mounted on the first bracket 20, the first bolts 41 sequentially penetrate through the connecting holes 32 and the first through holes 21, and then nuts 42 are screwed on the first bolts 41, so that the ignition coil body 30 can be mounted. By designing the two connecting seats 31 and the two fixing members 40 to be matched with each other, the installation firmness of the ignition coil body 30 is improved.

In one embodiment, the nuts 42 are secured to the bottom of the first bracket 20 by welding and aligned with a corresponding one of the first through holes 21. By integrating the nut 42 on the first bracket 20, when the ignition coil body 30 is installed, the ignition coil body 30 can be fixed by only aligning the connecting hole 32 with the first through hole 21 and screwing in the bolt, so that the installation flow is simplified, and the ignition coil has the characteristic of operation.

In one embodiment, the first bracket 20 is provided with two connection lugs 22, and a yielding gap 23 is formed between the two connection lugs 22. The two connecting seats 31 are respectively arranged on the corresponding connecting support lugs 22, and the ignition coil body 30 is positioned in the yielding gap 23. The structural design makes the ignition coil body 30 only have two connecting seats 31 which are respectively connected with the connecting lugs 22, and the ignition coil body 30 is positioned in the yielding gap 23, so that air flow more easily flows through the ignition coil body 30, thereby facilitating heat dissipation of the ignition coil body 30.

In one embodiment, the first bracket 20 is fixed to the engine body 10 by two second bolts 60, one end of the first bracket 20 away from the ignition coil body 30 is bent to form a connection plate 24, one end of the connection plate 24 away from the first bracket 20 is inclined upward, and the top of the connection plate 24 is bent to form a first support plate 25. The inclined connecting plate 24 can raise the height of the first support plate 25 and at the same time avoid the position of the cylinder head. Through the design of the first supporting plate 25, the oil tank shell (not shown in the attached drawing) of the engine can be supported and fixed, and the support frame is not required to be additionally designed to support the oil tank shell, so that the use of supporting pieces is reduced, and the integral structure of the engine is simplified.

In one embodiment, the connecting plate 24 is provided with a second through hole 26, and the design of the second through hole 26 reduces the overall weight of the first bracket 20 while ensuring the structural strength of the first bracket 20.

In one embodiment, the engine body 10 is provided with a second bracket 50, and the top of the second bracket 50 is bent to form a second support plate 51. Specifically, the top surface of the second support plate 51 is disposed flush with the top surface of the first support plate 25. Under the common support of the second support plate 51 and the first support plate 25, the installation firmness of the oil tank shell is improved, and the overall structure is more stable.
