Any limited number of modifications made by anyone within the scope of the claims of the present invention are still within the scope of the claims of the present invention.

[0022] The specific embodiment of the present invention is as follows: Figure 1-2 As shown, a flywheel housing transition plate is an integrally formed structure, comprising a connection plate 1, a sink groove 2 is provided at the front end of the connection plate 1, a clearance cavity 3 connected to the sink groove 2 is provided in the connection plate 1, a plurality of first mounting holes 4 arranged around the outline of the clearance cavity 3 are provided on the connection plate 1, a step structure 5 is provided on the side wall of the sink groove 2, a plurality of second mounting holes 6 are provided on the end surface of the step structure 5, a plurality of third mounting holes 7 arranged around the inner cavity of the connection plate 1 are provided on the connection plate 1, and the distribution of the plurality of third mounting holes 7 can be arranged according to the needs of the external connection structure, a positioning groove 8 is provided on the side wall of the sink groove 2 and the clearance cavity 3, and a fourth mounting hole 9 adapted to the two sides of the positioning groove 8 is provided on the step structure 5. In this flywheel housing transition plate, bolts can be passed through the first mounting hole 4 from the front end to the rear end to connect with the base, and the bolts can be hidden in the sink groove 2, and will not protrude from the front end surface of the connection plate 1 to interfere with other structures; and the bolts can be passed through the second mounting hole 4 from the front end to the rear end to connect with the cylinder body.

[0023] The flywheel housing or motor housing or gearbox housing can also be positioned and installed on the front end surface of the connecting disk 1 through the third mounting hole 7, so that when the engine cylinder body needs to be matched with the flywheel housing or motor housing or gearbox housing, there is no need to set different mounting holes in the engine cylinder body, and different external accessories can be installed by selecting a suitable transition plate; the hole spacing of the connecting holes at the connecting ends of structures such as the flywheel housing or motor housing or gearbox housing is usually unchanged, so the third mounting hole 7 can be adapted to the connecting holes of flywheel housings or motor housings or gearbox housings of different specifications. Therefore, the present connecting disk 1 can be connected to flywheel housings or motor housings or gearbox housings of different specifications without disassembling and replacing the connecting disk 1, thereby ensuring the accurate positioning of the connecting disk 1 and the installation accuracy of various accessories of the engine.

[0024] The flywheel housing transition plate can meet the requirements of rapid matching and assembly and disassembly of the same engine with different types of motors, thus realizing multiple matching of one engine and convenient operation. That is, the flywheel housing connected to the flywheel housing transition plate can be large or small to match different motors.

[0025] The positioning groove 8 can be used to install and position the starter structure of the motor, so that when the motor is installed on the connecting plate 1, the structure can be made more compact.

[0026] It can meet the matching needs of different and non-standard motors or gearboxes of different specifications, while achieving compact design as much as possible for easy manufacturing.

[0027] In this embodiment, the cross-section of the positioning groove 8 is a semicircular structure, which can make the outer cylindrical surface of the starter structure or the starter gear adapt to the arc surface of the positioning groove 8, so as to facilitate the quick and accurate installation of the starter structure. Moreover, the external structure of the engine can be arranged neatly, the structural layout is more compact, and the space occupied is small.

[0028] In this embodiment, a plurality of first mounting terminals 10 are arranged around the contour of the make way cavity 3 on the connection plate 1, and the first mounting hole 4 includes a through hole provided on the first mounting terminal 10 and the step structure 5, and the end face of the first mounting terminal 10 is adapted to the step surface of the step structure 5.

[0029] In this embodiment, the sink 2 is a stepped hole structure with a wide outer end and a narrow inner end. The step structure 5 is provided with a plurality of second mounting terminals 12 adapted to the front end surface of the connecting plate 1. The second mounting hole 6 is provided on the second mounting terminal 12. The length of the second mounting hole 6 can be lengthened by the second mounting terminal 12, so that when the bolt passes through the second mounting hole 6 and is locked with the cylinder body, the connecting plate 1 is firmly connected to the cylinder body and is not easy to loosen.

[0030] In this embodiment, the outer contour line of the connecting disk 1 is arranged around the inner cavity of the connecting disk 1, and a plurality of third mounting terminals 13 protruding from the outer side surface are provided on the outer side of the connecting disk 1. The end surface of the third mounting terminal 13 is adapted to the end surface of the second mounting terminal 12 and the front end surface of the connecting disk 1. The third mounting hole 7 is a through hole and a countersunk hole 11 provided on the third mounting terminal 13, and the countersunk hole 11 can make way for the head of the bolt.

[0031] The second mounting terminal 12 and the third mounting terminal 13 are respectively located inside and outside the shell of the connecting disk 1. By arranging a sealing gasket on the front end surface of the connecting disk 1, the sealing requirements of the inner cavity of the motor housing or the inner cavity of the gearbox housing can be achieved, and the water and dustproof requirements can be met.

[0032] In this embodiment, two fourth mounting terminals 14 are disposed on the step structure 5 at both sides of the slot of the positioning slot 8 , and the fourth mounting holes 9 are disposed on the fourth mounting terminals 14 .

[0033] In this embodiment, the connection plate 1 is a thin-walled structure, and a reinforcing rib 15 connected to the groove wall of the sink 2 is provided on the step surface of the step structure 5, which can improve the strength of the connection plate 1 and prevent the connection plate 1 from deformation.

[0034] The above are only preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which will not affect the effect of the implementation of the present invention and the practicality of the patent.
