[0002] The oil pan is usually located at the bottom of the engine and is made of metal, such as thin steel plate, cast iron or aluminum alloy. The main functions of the oil pan are to store lubricating oil, prevent impurities from entering, collect and store lubricating oil flowing back from the friction surfaces of the engine, dissipate some heat, and prevent lubricating oil from oxidizing. In order to filter out impurities in the lubricating oil flowing back from the friction surfaces of the engine, an oil suction pipe is usually installed inside the oil pan, and the lubricating oil will be filtered through the oil suction pipe and then enter the oil pan for storage.

[0003] In the related art, the oil suction pipe is a pipe that is bent and integrally molded. However, since the lubricating oil needs to pass through the oil suction pipe before entering the oil pan, impurities in the lubricating oil will also be adsorbed on the inner wall of the oil suction pipe after long-term use. Therefore, the impurities adhering to the inner wall of the oil suction pipe need to be cleaned after a period of use, which will affect the quality of the lubricating oil entering the oil pan. Since the oil suction pipe has a bend and is an integrally molded pipe, it is inconvenient to clean its inner wall. Utility Model Content

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-4 This application is described in further detail.

[0024] The present application embodiment discloses an oil pan. Figure 1 and Figure 2 The oil pan includes a bottom shell body 1 and an oil suction pipe 2. A storage cavity 11 for storing lubricating oil is provided on the top of the bottom shell body 1, and the oil suction pipe 2 is located at the bottom of the storage cavity 11. The oil suction pipe 2 includes an upper half pipe shell 21 and a lower half pipe shell 22, and the upper half pipe shell 21 and the lower half pipe shell 22 are connected to each other on one side thereof to form a channel for the flow of lubricating oil. The upper half pipe shell 21 can be detachably mounted on the lower half pipe shell 22, and the lower half pipe shell 22 can be detachably mounted in the storage cavity 11. When it is necessary to clean the interior of the oil suction pipe 2, the upper half pipe shell 21 can be directly removed from the lower half pipe shell 22, and then the cleaning can be performed, so that the cleaning process is not affected by the shape of the oil suction pipe 2, and the cleaning is more convenient.

[0025] Reference Figure 2 and Figure 3 A vertical pipe 12 is formed integrally with the bottom shell body 1 on the cavity wall on one side of the storage cavity 11, and the vertical pipe 12 extends along the depth of the storage cavity 11 to the cavity bottom of the storage cavity 11. A connecting port 13 communicating with the interior of the vertical pipe 12 is provided on the outer wall of the vertical pipe 12 near the cavity bottom of the storage cavity 11, and an opening at one end of the lower half pipe shell 22 near the vertical pipe 12 is connected with the connecting port 13, so that the lubricating oil can enter the oil suction pipe 2 from the vertical pipe 12. A connecting edge 221 is formed integrally on the side of the lower half pipe shell 22 near the vertical pipe 12, and the connecting edge 221 is located outside the connecting port 13. Bolts will pass through the connecting edge 221 to install the side of the lower half pipe shell 22 near the vertical pipe 12 on the vertical pipe 12. The lower half pipe shell 22 increases the contact area with the vertical pipe 12 through the connecting edge 221, thereby improving the stability after connection.

[0026] Combination Figure 2 Reference Figure 3 and Figure 4A support leg 222 is integrally formed on the outer wall of the lower half pipe shell 22 away from the connecting edge 221. The support leg 222 extends toward the bottom of the storage chamber 11 and abuts against the bottom of the storage chamber 11. The side of the lower half pipe close to the bottom of the storage chamber 11 will be separated from the bottom of the storage chamber 11 by a certain gap through the support leg 222. At the same time, the support leg 222 will be installed on the bottom of the storage chamber 11 by bolts.

[0027] A liquid discharge port 223 is provided on one side of the lower half pipe shell 22 close to the bottom of the storage chamber 11. The liquid discharge port 223 is communicated with the interior of the lower half pipe shell 22, and the liquid discharge port is located on the side of the lower half pipe shell 22 where the support leg 222 is provided. A filter screen 224 is also installed at the liquid discharge port 223. Since the lower half pipe shell 22 can be separated from the bottom of the storage chamber 11 by a certain gap under the action of the support leg 222, the lubricating oil will be discharged from the liquid discharge port 223 into the storage chamber 11 after being filtered by the filter screen 224.

[0028] Combination Figure 2 Reference Figure 3 and Figure 4 A circular docking slot 225 is provided on the wall thickness of the lower half pipe shell 22 close to the upper half pipe shell 21, and a docking protrusion 211 inserted into the docking slot 225 is provided on the wall thickness of the upper half pipe shell 21 close to the lower half pipe shell 22. The docking protrusion 211 is integrally formed with the upper half pipe shell 21, and the docking protrusion 211 is inserted into the docking groove so that the upper half pipe shell 21 and the lower half pipe shell 22 can be positioned and installed during installation.

[0029] A sealing ring 23 is installed in the docking groove, and the inner peripheral wall of the sealing ring 23 is pressed against the outer peripheral wall of the docking flange 211, thereby increasing the sealing performance of the joint between the upper half pipe shell 21 and the lower half pipe shell 22, so that the lubricating oil that has not been filtered by the filter screen 224 is not easy to leak out from here.

[0030] Combination Figure 2 Reference Figure 3 and Figure 4 The upper half pipe shell 21 has two opposite side walls integrally formed with upper connecting ears 212, and each upper connecting ear 212 has a bolt hole penetrating through it on the side facing away from the lower half pipe shell 22; the lower half pipe shell 22 has two opposite side walls integrally formed with lower connecting ears 226, which are located below the upper connecting ears 212 and fit the upper connecting ears 212, and the lower connecting ears 226 have a threaded hole connected to the bolt hole on the upper connecting ears 212 on the side close to the upper connecting ears 212, and the bolts are threadedly installed in the bolt holes and the threaded holes to fix the upper half pipe shell 21 and the lower half pipe shell 22. The number of the lower connecting ears 226 is the same as the number of the upper connecting ears 212 and corresponds to each other.

[0031] The implementation principle of an oil pan in an embodiment of the present application is as follows: since the upper pipe shell 21 and the lower pipe shell 22 are fixed together by bolts, when cleaning the inside of the oil suction pipe 2, the bolts connected to the upper connecting lug 212 and the lower connecting lug 226 can be removed by using a screwdriver tool, and then the upper pipe shell 21 can be removed from the lower pipe shell 22, and then the inside of the upper pipe shell 21 and the lower pipe shell 22 can be cleaned respectively.

[0032] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
