[0029] According to a first aspect of this utility model, an engine front cover is provided, such as... Figures 2 to 5 As shown, in this embodiment, the engine front cover has a main body 100, which includes a flat plate portion 1 and an expansion portion 2. The expansion portion 2 increases the mounting space for the engine front components. Furthermore, the main body 100 is provided with a first reinforcing portion and a second reinforcing portion, which effectively increases the structural strength of the main body 100, improves its stability, and thus effectively reduces vibration to lower engine noise. The specific structure and connection relationships of the aforementioned parts of the engine front cover according to this invention will be described in detail below.
[0030] In addition, the main body 100 is provided with a plurality of bolt holes 3 for fixing the main body 100 to the engine block, such as Figures 2 to 5 As shown, multiple bolt holes 3 are spaced apart along the outer contour of the main body 100, and each bolt hole 3 penetrates both ends of the main body 100 in the thickness direction. In addition, the main body 100 also has a fan mounting hole 41 and a crankshaft mounting hole 42. The fan mounting hole 41 is located in the flat plate portion 1, and the crankshaft mounting hole 42 is located in the expansion portion 2. The bolt holes 3, fan mounting holes 41, and crankshaft mounting holes 42 are all inherent structures of existing front cover plates; therefore, their structure, function, and specifications will not be described in detail.
[0031] In this embodiment, as Figures 2 to 3As shown, the flat plate portion 1 is located in the upper half of the main body 100, and the expansion portion 2 is located in the lower half of the main body 100. Along the thickness direction of the main body 100, the expansion portion 2 is formed as a protruding structure that arches towards the first end away from the main body 100, that is, the end face of the first end of the expansion portion 2 is higher than the end face of the first end of the flat plate portion 1. However, there is no specific limitation on the protrusion height of the expansion portion 2. Furthermore, there are no specific limitations on the specifications of the expansion portion 2 itself and the specifications of the flat plate portion 1 itself, such as their size. They should be determined comprehensively according to the actual situation, such as engine specifications, as long as the above-mentioned technical effects of expansion and increasing the strength of the main body 100 can be achieved.
[0032] Specifically, along the thickness direction of the main body 100, a first reinforcing portion is provided at the end face of the first end of the expansion portion 2, and the first reinforcing portion protrudes from the end face of the first end of the expansion portion 2. More specifically, as... Figures 2 to 3 As shown, the first reinforcing part in this embodiment includes a first reinforcing rib 51 and a second reinforcing rib 52. The first reinforcing rib 51 is formed as a closed ring structure that corresponds to and fits the outer contour of the end face of the first end of the expansion part 2. Furthermore, the first reinforcing rib 51 has a relief recess corresponding to the bolt hole 3, and the outer side of the crankshaft mounting hole 42 is also provided with a first reinforcing rib 51. This can increase the reinforcing effect of the first reinforcing part on the main body 100, and can also effectively improve the structural strength of the bolt hole 3 and the crankshaft mounting hole 42.
[0033] Furthermore, multiple second reinforcing ribs 52 are staggered within the space enclosed by the first reinforcing ribs 51 and connected to the first reinforcing ribs 51, such as... Figure 3 As shown, after the first reinforcing rib 51 and the second reinforcing rib 52 are connected, a plurality of polygonal voids 57 are formed. In this embodiment, there are no specific restrictions on the distribution and number of the second reinforcing ribs 52. Therefore, there are no specific restrictions on the structure of the voids 57. For example, its cross-sectional shape can be triangular, quadrilateral or pentagonal. Such a setting can effectively improve the reinforcing effect of the first reinforcing part on the main body 100.
[0034] In this embodiment, the expansion section 2 also forms a corresponding receiving groove 21. The opening of the receiving groove 21 is located at the second end in the thickness direction of the main body 100. The specifications of the receiving groove 21, such as its depth and size, are not specifically limited and should be determined according to the actual situation, such as the space requirements of the internal components of the engine front end of different models.
[0035] like Figures 4 to 5As shown, a second reinforcing portion is formed at the bottom of the receiving groove 21. The second reinforcing portion includes multiple third reinforcing ribs 53 and multiple fourth reinforcing ribs 54. Specifically, the third reinforcing ribs 53 are formed into an arc-shaped structure corresponding to the crankshaft mounting hole 42. The multiple third reinforcing ribs 53 are arranged sequentially in a radial direction away from the crankshaft mounting hole 42 with the crankshaft mounting hole 42 as the "center". The end of each third reinforcing rib 53 is connected to the inner wall of the receiving groove 21. The fourth reinforcing ribs 54 are formed into a straight structure. The multiple fourth reinforcing ribs 54 are also formed into a diverging structure with the crankshaft mounting hole 42 as the "center". That is, each fourth reinforcing rib 54 extends radially along the crankshaft mounting hole 42, and the two ends of each fourth reinforcing rib 54 are connected to the side wall of the crankshaft mounting hole 42 and the side wall of the receiving groove 21, respectively.
[0036] It should be noted that there are no restrictions on the specific structural dimensions of the first and second reinforcing parts. That is, there are no specific restrictions on the specifications, quantity, and placement of the first reinforcing rib 51, the second reinforcing rib 52, the third reinforcing rib 53, and the fourth reinforcing rib 54, as long as the above-mentioned technical effect of improving the structural strength of the main body 100 can be achieved.
[0037] In this embodiment, as Figure 3 As shown, two of the aforementioned bolt holes 3 are located at the connection between the flat plate portion 1 and the expanded portion 2, namely the first bolt hole 31 and the second bolt hole 32. The outer walls of the first bolt hole 31 and the second bolt hole 32 are provided with third reinforcing portions to prevent the main body 100 from breaking or failing at the connection between the flat plate portion 1 and the expanded portion 2, thereby effectively improving the structural strength of the main body 100. In this embodiment, the third reinforcing portion forms a fifth reinforcing rib 55 at the first bolt hole 31, and the third reinforcing portion forms a reinforcing barrier 56 as shown in the figure at the second bolt hole 32.
[0038] According to the engine front cover of this utility model, a protruding expansion portion 2 is provided at the main body 100 of the engine front cover. The expansion portion 2 also forms a receiving groove 21. Compared with the existing flat front cover, the front cover of this utility model expands the installation space of the components at the front end of the engine. In addition, the front cover of this utility model is provided with a first reinforcing portion and a second reinforcing portion at the end faces of the two ends of the expansion portion 2, thereby increasing the strength of the main body 100 itself, that is, increasing the structural stability of the main body 100, thereby reducing the vibration of the main body 100 and effectively reducing engine noise.
[0039] According to a second aspect of the present invention, an engine is provided, wherein the engine includes an engine front cover as described above.
[0040] According to a third aspect of the present invention, a vehicle is provided, wherein the vehicle includes the engine described above.
[0041] Finally, it should be noted that the above-described embodiments are merely specific implementations of this application, used to illustrate the technical solutions of this application, and not to limit them. The protection scope of this application is not limited thereto.
