In order to avoid the leakage of the engine oil stored in the oil pot 2, the oil pot 2 can be fixed through the first connecting structure 21 on the top of the oil pot 2. For example, the first locking member 6 is a bolt, an installation through hole is designed on the top of the oil pot 2, and the first mounting position 11 on the timing cover 1 also forms an installation through hole. The bolt passes through the installation through holes on the oil pot 2 and the timing cover 1 and is finally connected to the threaded hole on the engine body 5, so as to ensure the firmness of the connection between the oil pot 2 and the engine body 5.

[0064] In some embodiments of the present application, referring to FIG. 3, the engine further comprises a buffer structure 4, and the buffer structure 4 is clamped between the first connecting structure 21 and the first mounting position 11.

[0065] In this embodiment, the buffer structure 4 can comprise a mounting gasket and a damping pad.

In order to facilitate the connection between the bottom of the oil can 2 and the engine body 5, the mounting bracket 3 can be used to connect the oil can 2 and the engine body 5.

[0073] The second mounting position 31 and the third mounting position 32 can be mounting through holes, and the second mounting position 31 is locked on the second connecting structure 22 and the third connecting structure 23 at the bottom of the oil can 2 by the second locking member of the bolt structure, and the third mounting position 32 is locked on the machine body 5 by the third locking member of the bolt structure, thereby achieving effective connection between the oil can 2 and the machine body 5.

[0077] In some embodiments of the present application, the oil can 2 has an axis of inertia passing therethrough, the axis is parallel to the up-down direction of the vehicle, and the second connecting structure 22 and the third connecting structure 23 are located on both sides of the axis.

[0078] In this embodiment, referring to FIGS. 9 and 10, the bottom of the oil can 2 forms two mounting points through the second connecting structure 22 and the third connecting structure 23, and the two mounting points of the second connecting structure 22 and the third connecting structure 23 are located on both sides of the centroid of the oil can 2, respectively, and the oil can 2 is connected to the machine body 5 through the two mounting points at the bottom of the oil can 2, so as to support the oil can at the bottom of the oil can 2; and the second connecting structure 22 and the third connecting structure 23 at the bottom of the oil can 2 cooperate with the first connecting structure 21 at the top of the oil can 2 to form three-point fixing of the oil can 2, and the three fixing points can bear forces in multiple directions on the oil can 2, so as to prevent the oil can 2 from shaking during operation of the vehicle.

[0079] In some embodiments of the present application, referring to FIG. 3, the bottom of the oil can 2 protrudes downward from the timing cover 1, the mounting bracket 3 passes through the bottom of the timing cover 1 and connects the oil can 2 and the machine body 5, so that the oil can 2 is fixed to the side of the timing cover 1 away from the machine body 5, thereby improving the stability of the oil can 2, the timing cover 1 and the machine body 5 fixed together.

[0080] In some embodiments of the present application, referring to FIG. 4, the mounting bracket 3 comprises a first mounting plate 33 and a second mounting plate 34, and a bending angle is formed between the first mounting plate 33 and the second mounting plate 34. The second mounting position 31 is located on the first mounting plate 33, and the third mounting position 32 is located on the second mounting plate 34.

[0081] In this embodiment, in order to facilitate the connection of the second connecting structure 22 and the third connecting structure 23 of the bottom of the oil can 2 with the mounting bracket 3, the connection directions of the second mounting position 31 and the third mounting position 32 are difficult to keep consistent. However, when the bending angle between the first mounting plate 33 and the second mounting plate 34 is, for example, in the range of 60°-120°, the connection of the oil can 2 on the first mounting plate 33 and the connection of the second mounting plate 34 with the machine body 5 can be ensured to be mutually independent.

[0082] In some embodiments of the present application, as shown in FIG. 4, the bending angle between the first mounting plate 33 and the second mounting plate 34 is 90°, the oil can 2 is connected to the machine body 5 through the bending structure formed by the first mounting plate 33 and the second mounting plate 34, and the wall thickness of the machine body 5 is large enough to withstand the shaking force caused by the shaking of the oil liquid in the oil can 2, thereby improving the reliability of the fixation of the oil can 2.

[0083] In some embodiments of the present application, as shown in FIG. 4, the mounting bracket 3 further comprises at least one reinforcing rib 35, which is arranged at the bending angle between the first mounting plate 33 and the second mounting plate 34.

[0084] In this embodiment, when the first mounting plate 33 and the second mounting plate 34 are bent relative to each other at the connection position, the shaking of the oil can 2 relative to the machine body 5 will drive the first mounting plate 33 to move relative to the second mounting plate 34, so that the stress between the first mounting plate 33 and the second mounting plate 34 is concentrated at the connection position. However, the reinforcing rib 35 is arranged at the bending angle between the first mounting plate 33 and the second mounting plate 34, which can strengthen the strength of the connection position on the mounting bracket 3 and ensure the stability of the connection of the oil can 2 with the machine body 5.

[0085] In some embodiments of the present application, referring to FIG. 15, the bushing nut 9 is embedded in the second connecting structure 22, and the second locking member 7 has a second locking cap 71 and a thread 72 at both ends, respectively. The thread 72 is screwed with the bushing nut 9 to clamp the first mounting plate 33 between the second locking cap 71 and the second connecting structure 22.

[0086] In this embodiment, the bushing nut 9 is embedded in the second connecting structure 22, which can ensure the structural integrity of the bushing nut 9 and the oil can 2; and the second locking member 7 can be screwed with the bushing nut 9 through the threads 72 at the end of the second locking member 7 when the first mounting plate 33 passes through the first mounting plate 33, so as to fasten the first mounting plate 33 on the oil can 2 and ensure the connection strength between the mounting bracket 3 and the oil can 2.

[0087] In some embodiments of the present application, referring to FIG. 15, the engine further comprises a buffer sleeve 10, the second mounting position 31 is a mounting hole, and the buffer sleeve 10 is embedded in the mounting hole. Part of the buffer sleeve 10 protrudes from one end of the mounting hole and is clamped between the second connecting structure 22 and the first mounting plate 33, and part of the buffer sleeve 10 protrudes from the other end of the mounting hole and is clamped between the first mounting plate 33 and the second locking cap 71.

[0088] In some embodiments of the present application, the buffer sleeve 10 is a sleeve structure. When the buffer sleeve 10 is assembled in the mounting hole of the mounting bracket 3, part of the buffer sleeve 10 is on both sides of the mounting hole, and the buffer sleeve 10 is already in a compressed state.
