They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0038] Please refer to Figure 1 As shown, in the prior art, the cylinder block 1 is composed of an upper cylinder block 11 and a lower cylinder block 12, and the oil pan 2 is mounted at the bottom of the cylinder block 1. The oil pan 2 needs to be fixed to the bottom of the cylinder block 1 with fixing bolts, which increases the overall height of the engine, which is not conducive to the overall vehicle layout. Furthermore, the method of fixing the oil pan 2 with additional fixing bolts will increase the product cost and is not conducive to product competitiveness.

[0039] Therefore, the embodiments of this application provide a cylinder block, engine and vehicle with an integrated oil pan. Compared with the prior art, the present application eliminates the traditional design of the oil pan and the fixing bolts for fixing the oil pan, which can significantly save costs and improve product competitiveness.

[0040] The following is a detailed description of a cylinder block with an integrated oil pan provided in this embodiment. Please refer to [link / reference]. Figures 2-5 As shown, it includes: a first cylinder body 13 and a second cylinder body 14. The bottom of the first cylinder body 13 is provided with a first oil reservoir 131; the bottom of the second cylinder body 14 is provided with a second oil reservoir 141. The first cylinder body 13 and the second cylinder body 14 are assembled together in a horizontal direction to form a cylinder body 1, and the bottom position of the cylinder body 1 is combined with the shell of the first oil reservoir 131 and the shell of the second oil reservoir 141 to form a complete oil pan 2.

[0041] In this embodiment, the cylinder block 1 adopts a horizontally opposed design, consisting of a first cylinder block 13 and a second cylinder block 14. The first cylinder block 13 and the second cylinder block 14 are assembled together horizontally to form the cylinder block 1. A first oil reservoir 131 is provided at the bottom of the first cylinder block 13, and a second oil reservoir 141 is provided at the bottom of the second cylinder block 14. When assembling and connecting to form the cylinder block 1, the bottom position of the cylinder block 1, through the combination of the shells of the first oil reservoir 131 and the second oil reservoir 141, forms a complete oil pan 2. Compared with the prior art where the cylinder block 1 is fixed at its bottom by screws... Regarding the method of adding an additional oil pan 2 for fixing, the method of this application is equivalent to integrating the oil pan 2 into the bottom of the cylinder block 1. After lubricating the various friction pairs, the lubricating oil can flow back to the bottom of the cylinder block 1. The bottom of the cylinder block 1 acts as the oil pan 2, which can collect and store the lubricating oil, thereby eliminating the need for the oil pan 2 in the prior art. This avoids the situation where the overall height of the engine increases, which is not conducive to the overall vehicle layout. Furthermore, by eliminating the design of the oil pan 2 in the prior art, the fixing bolts for fixing the oil pan 2 can also be eliminated, which can significantly save costs and improve product competitiveness.

[0042] It should also be noted that the first oil reservoir 131 includes a first opening mating surface and a first cavity, and the second oil reservoir 141 includes a second opening mating surface and a second cavity. When the first cylinder body 13 and the second cylinder body 14 are assembled and joined together in the horizontal direction to form the cylinder body 1, the first opening mating surface of the first oil reservoir 131 and the second opening mating surface of the second oil reservoir 141 are joined and assembled together, and the first cavity and the second cavity are interconnected. Thus, the first oil reservoir 131 and the second oil reservoir 141 are combined to form the oil reservoir of the oil pan 2. Of course, in order to ensure the sealing of the mating surface, the contact surface of the first opening mating surface and the second opening mating surface is selected for sealing treatment. Preferably, adhesive is used for sealing. Of course, this embodiment does not impose specific limitations and can be selected according to the actual situation. At the same time, adhesive is also applied to seal the entire mating surface of the first cylinder body 13 and the second cylinder body 14. Since the cylinder body 1 is composed of the first cylinder body 13 and the second cylinder body 14, in order to ensure the sealing of the mating surface, adhesive is applied to seal the entire mating surface of the first cylinder body 13 and the second cylinder body 14.

[0043] Please continue to refer to Figures 2-5 As shown in this embodiment, it should be noted that a first oil baffle 3 is provided in the first oil storage chamber 131, and a second oil baffle 4 is provided in the second oil storage chamber 141. The first oil baffle 3 and the second oil baffle 4 are joined at the joint surface of the first oil storage chamber 131 and the second oil storage chamber 141 to form the oil baffle of the oil pan 2.

[0044] The oil pan 2 in this application is formed by assembly. Therefore, the oil baffle plate adapted to the oil pan 2 is also set in a separate manner. The first oil baffle plate 3 is integrally cast in the first oil reservoir 131, and the second oil baffle plate 4 is integrally cast in the second oil reservoir 141. In this way, when the first cylinder block 13 and the second cylinder block 14 are assembled together in the horizontal direction to form the cylinder block 1, the first oil baffle plate 3 and the second oil baffle plate 4 are also assembled together in the horizontal direction to form the oil baffle plate of the oil pan 2. Furthermore, the first oil baffle plate 3 and the second oil baffle plate 4 are both horizontally arranged. The first oil baffle plate 3 divides the interior of the first oil reservoir 131 into a first upper oil reservoir 1311 and a first lower oil reservoir 1312. Similarly, the second oil baffle plate 4 divides the interior of the second oil reservoir 141 into a second upper oil reservoir 1411 and a second lower oil reservoir 1412. In this embodiment, the interior of the oil pan 2 is divided into an upper oil reservoir 21 and a lower oil reservoir 22, which facilitates the subsequent installation of the oil filter 6 on the first baffle plate 3 and / or the second baffle plate 4. The oil inlet pipe 61 of the oil filter 6 extends to the bottom of the lower oil reservoir 22. In this way, it can be ensured that there is always lubricating oil in the lower oil reservoir 22, which can prevent the problem of lubricating oil splashing causing the oil inlet pipe 61 of the oil filter 6 to not be able to draw lubricating oil. Even when the vehicle tilts uphill, a small amount of oil can still be blocked by the baffle plate and left in the lower oil reservoir 22 to prevent the vehicle from stalling.

[0045] Please refer to Figures 6-11 As shown in the figure, in this embodiment, it should also be noted that when the first oil baffle 3 and the second oil baffle 4 are assembled and connected, the first upper oil storage cavity 1311 and the second upper oil storage cavity 1411 combine to form the upper oil storage cavity 21 of the oil pan 2, and the first lower oil storage cavity 1312 and the second lower oil storage cavity 1412 combine to form the lower oil storage cavity 22 of the oil pan 2. In order to ensure that the lubricating oil between the upper oil storage cavity 21 and the lower oil storage cavity 22 can communicate, in this embodiment, a gap 5 is reserved at the joint of the first oil baffle 3 and the second oil baffle 4. The gap 5 connects the upper oil storage cavity 21 and the lower oil storage cavity 22. Thus, after the lubricating oil lubricates each friction pair, it can flow back into the upper oil storage cavity 21 of the oil pan 2, and then flow into the lower oil storage cavity 22 through the gap 5.

[0046] An oil filter 6 is also provided in the upper oil storage chamber 21. The function of the oil filter 6 is to filter out larger particles and impurities in the oil. A filter clearance space 7 is provided on the first oil baffle 3 and / or the second oil baffle 4. The filter clearance space 7 is used to assemble the oil filter 6. An oil inlet pipe 61 is provided at the bottom of the oil filter 6. The oil inlet pipe 61 extends into the lower oil storage chamber 22 of the oil pan 2.

[0047] In one example, this application provides a filter clearance space 7 on the side of the second oil baffle 4 that is used to connect with the first oil baffle 3. When the first oil baffle 3 and the second oil baffle 4 are connected, the filter clearance space 7 is located between the first oil baffle 3 and the second oil baffle 4. The oil filter 6 is installed in the filter clearance space 7, and the oil inlet pipe 61 at the bottom of the oil filter 6 extends into the lower oil storage chamber 22 of the oil pan 2. In this way, the oil filter 6 can draw and filter the lubricating oil in the lower oil storage chamber 22. By installing the oil filter 6 in the filter clearance space 7 between the first oil baffle 3 and the second oil baffle 4, and extending the oil inlet pipe 61 into the lower oil storage chamber 22 of the oil pan 2, that is, below the first oil baffle 3 and the second oil baffle 4, the problem of lubricating oil splashing causing the oil filter 6 to fail to draw lubricating oil can be prevented.

[0048] Of course, the filter clearance space 7 can also be designed on the side of the first baffle plate 3 that is used to dock with the second baffle plate 4, depending on the arrangement. In this embodiment, no specific restrictions are imposed, and it can be selected according to actual needs.

[0049] In this embodiment, it should also be noted that an oil pump 8 and an oil filter 9 are also provided on the first cylinder block 13 or the second cylinder block 14. The oil pump 8 is fixedly installed on the first cylinder block 13 or the second cylinder block 14 by bolts or other means, and the oil pump 8 is connected to the oil outlet pipe of the oil strainer 6 through an oil suction pipe. The oil filter 9 is installed on the first cylinder block 13 or the second cylinder block 14 by bolts or other means. An oil filtering chamber is formed inside the oil filter 9, and an oil inlet and an oil outlet are provided on the outside of the oil filter 9, which are connected to the oil filtering chamber. The oil inlet is connected to the oil pump 8, and the oil outlet is connected to the pipeline leading to the component to be lubricated. Thus, under the action of the oil pump 8, the lubricating oil flows into the oil pump 8 after coarse filtration by the oil strainer 6, and then flows into the oil filter 9 for fine filtration before being delivered to the various friction pairs of the engine.

[0050] Please refer to Figures 12-15 As shown in the illustration, in this embodiment, it should also be noted that an oil drain hole is provided on one side of the lowest point of the bottom of the oil pan 2, and an oil drain bolt 101 for sealing is provided in the oil drain hole. In this application, an oil drain hole is provided on one side of the lowest point of the bottom of the oil pan 2, the oil drain hole is connected to the lower oil storage chamber 22 of the oil pan 2, and an oil drain bolt 101 is provided in the oil drain hole, so that when oil needs to be drained, the oil drain bolt 101 can be unscrewed, which is convenient to operate.

[0051] In this embodiment, it should also be noted that a cover 102 is mounted on the front end of the cylinder body 1.

[0052] In this embodiment, an engine is also provided, including the cylinder block with the integrated oil pan described above.

[0053] In this embodiment, there is also a vehicle that includes the engine described above.

[0054] The implementation principle of this embodiment is as follows: The cylinder block 1 in this embodiment adopts a horizontally opposed design. The cylinder block 1 is divided into a first cylinder block 13 and a second cylinder block 14. The bottom of the first cylinder block 13 is designed as a first oil reservoir 131 with the function of an oil pan, and the bottom of the second cylinder block 14 is designed as a second oil reservoir 141 with the function of an oil pan. Thus, the first cylinder block 13 and the second cylinder block 14 are assembled together so that the shell of the first oil reservoir 131 and the shell of the second oil reservoir 141 combine to form a complete oil pan 2. After the lubricating oil lubricates the various friction pairs, it can flow back to the bottom of the cylinder block 1. Since the bottom of the cylinder block 1 acts as the oil pan 2, it can collect and store lubricating oil. The cylinder block 1 design in this embodiment includes all the functions of the oil pan 2, so the oil pan 2 can be eliminated from the whole machine. By eliminating the oil pan 2 and the fixing bolts for fixing the oil pan 2 designed in the prior art, the cost can be greatly reduced, the product competitiveness can be improved, and the situation where the overall height of the engine increases is not conducive to the overall vehicle layout can also be avoided.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
