[0020] The present invention will be further described below in conjunction with the accompanying drawings and embodiments. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom," "top," "inner," and "outer" refer to directions toward or away from the geometric center of a particular component, respectively.

[0021] Reference Figures 1 to 3As shown, the cover assembly of this embodiment includes a cover 1, and two pins 11 are connected to the cover 1, wherein the pins 11 and the cover 1 are integrally formed, and the two pins 11 are respectively located on opposite sides of the cover 1, and the pins 11 respectively correspond to the two legs 21 of the crankcase 2, and the legs 21 are provided with fixing holes 211, and the pins 11 are provided with connecting holes 111 corresponding to the fixing holes 211. The cover 1 is fixed to the corresponding legs 21 through the pins 11, thereby reducing the provision of the first connecting hole 111 on the crankcase 2 and the provision of the second connecting hole 111 on the cover 1, and reducing the number of connection positions. Only two pins 11 need to be connected to two legs 21, thereby improving installation efficiency.

[0022] In order to facilitate the connection of standard parts such as bolts, an internal thread can be opened in the fixing hole 211, wherein the connecting hole 111 is a waist-shaped hole, which increases the installation tolerance between the connecting hole 111 and the fixing hole 211 and facilitates the fixation between the cover 1 and the crankcase 2.

[0023] Reference Figure 2 As shown, two accommodating spaces 12 are formed on the side of the cover 1 facing the support leg 21, and the support leg 21 extends into the corresponding accommodating space 12, providing space for the support leg 21 to be placed, so that the distance between the two support legs 21 can be reduced, and the support legs 21 are hidden. The support legs 21 and the corresponding pins 11 are stacked up and down. In this embodiment, the support legs 21 are located above the corresponding pins 11.

[0024] Reference Figure 1 and Figure 2 As shown, the cover 1 and the crankcase 2 are snap-fitted together to increase the connection strength between the cover 1 and the crankcase 2 and prevent a large gap from forming between the end of the cover 1 away from the pin 11 and the crankcase 2 .

[0025] Reference Figure 2 As shown, a plurality of snap fasteners 13 are formed on the side of the cover 1 facing the crankcase 2. In this embodiment, there are three snap fasteners 13, one of which is located at the bottom of the side of the cover 1 facing the crankcase 2, and the other two snap fasteners 13 are located on opposite sides of the cover 1 facing the crankcase 2, and the positions and heights of the two snap fasteners 13 are the same. The snap fasteners 13 can be snapped together with the crankcase 2, thereby increasing the connection stability between the cover 1 and the crankcase 2.

[0026] The fastener 13 may also be provided on the crankcase 2. Preferably, the fastener 13 is provided on the cover 1, which makes the structure simpler.
