The upper surface of the first oil guide plate 5 is inclined. The lower end of the upper surface of the first oil guide plate 5 is close to the second cavity. A first oil guide groove 6 is formed on the upper surface of the first oil guide plate 5. The first oil guide groove 6 has the same inclination angle as the upper surface of the first oil guide plate 5. Four second oil guide plates 7 are fixedly connected to the bottom of the inner side of the second cavity. The four second oil guide plates 7 are arranged in a field shape. An oil discharge port 8 is opened at an end corner position of the four second oil guide plates 7 close to each other. The upper surfaces of the four second oil guide plates 7 are all inclined, and the lower end corners of the four second oil guide plates 7 are all close to the oil discharge port 8; the four second oil guide plates 7 are each provided with a second oil guide groove 12 on the side that is in contact with the adjacent second oil guide plate 7. The second oil guide groove 12 is arranged obliquely, and the lower end of the second oil guide groove 12 is close to the oil discharge port 8. The protective outer shell 2 is sleeved on the top of the outer side of the bottom shell body 1. The top edge of the bottom shell body 1 is evenly provided with mounting holes 10. The mounting holes 10 are located on the inner side of the protective outer shell 2. The protective outer shell 2 is used to protect the mounting holes 10 and the bolts installed in the mounting holes 10. The protective outer shell 2 is buckled and connected to the bottom shell body 1 through a limit assembly. The protective bracket body 3 is arranged at the bottom of the bottom shell body 1. Both ends of the protective bracket body 3 are detachably connected to the protective outer shell 2. The protective bracket body 3 is used to protect the bottom of the bottom shell body 1; The sealing gasket body 4 is arranged at the top edge of the bottom shell body 1 and is used for sealing between the bottom shell body 1 and other components after installation.

[0025] The automobile engine oil pan provided by the present invention has a structural design of the first cavity inside the pan body 1 and the bottom of the second cavity. When changing the oil, the oil in the first cavity and the second cavity can be guided to flow to the position of the oil drain port 8, so that the oil can be discharged from the oil drain port 8, and the internal impurities can be discharged outward along with the oil, and the residual oil and impurities in the pan body 1 can be effectively reduced, thereby reducing the adverse effects of the retained oil and impurities on the maintenance cycle of the entire vehicle and the engine life.

[0026] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0027] Example 1: Please refer to Figure 1 - Figure 4 , an automobile engine oil pan, comprising: The bottom shell body 1 has a first cavity and a second cavity formed inside the bottom shell body 1. The first cavity and the second cavity are connected to each other. The inner wall and the outer side of the bottom shell body 1 are provided with reinforcing ribs. The reinforcing ribs can effectively improve the overall strength of the bottom shell body 1, reduce the deformation of the bottom shell body 1, and effectively extend the service life of the bottom shell body 1. Furthermore, a first oil guide plate 5 is fixedly connected to the bottom inner side of the first cavity, and the upper surface of the first oil guide plate 5 is inclined. The lower end of the upper surface of the first oil guide plate 5 is the end close to the second cavity. A first oil guide groove 6 is provided on the upper surface of the first oil guide plate 5, and the first oil guide groove 6 has the same inclination angle as the upper surface of the first oil guide plate 5. Through the cooperation of the first oil guide plate 5 and the first oil guide groove 6, it can be seen that when changing the oil, the oil in the first cavity is guided to flow into the second cavity, reducing the oil and impurities retained in the first cavity, and reducing the retained oil and impurities have an adverse effect on the maintenance cycle of the entire vehicle and the engine life.

[0028] Furthermore, four second oil guide plates 7 are fixedly connected to the bottom inner side of the second cavity. The four second oil guide plates 7 are arranged in a field shape. An oil drain port 8 is provided at an end corner position close to each other on the four second oil guide plates 7. The upper surfaces of the four second oil guide plates 7 are all inclined, and the lower end corners of the four second oil guide plates 7 are all end corners close to the oil drain port 8; the four second oil guide plates 7 are each provided with a second oil guide groove 12 on one side that is in contact with the adjacent second oil guide plates 7. The second oil guide groove 12 is arranged obliquely, and the lower end of the second oil guide groove 12 is the end close to the oil drain port 8. It can be seen that when changing the oil, the four second oil guide plates 7 can guide the oil and impurities in the second cavity and the first cavity so that they can flow towards the oil drain port 8, thereby reducing the oil and impurities retained in the second cavity, and reducing the adverse effects of the retained oil and impurities on the maintenance cycle of the vehicle and the engine life.

[0029] The protective outer shell 2 is sleeved on the top of the outer side of the bottom shell body 1. Mounting through holes 10 are evenly opened on the top edge of the bottom shell body 1. The mounting through holes 10 are located on the inner side of the protective outer shell 2. The protective outer shell 2 is used to protect the mounting through holes 10 and the bolts installed in the mounting through holes 10. The protective outer shell 2 and the bottom shell body 1 are snap-fitted together by a limiting assembly; after the bottom shell body 1 is connected to other components through screws or bolts in conjunction with the mounting through holes 10, the protective outer shell 2 is sleeved on the outside of the bottom shell body 1 and the installed screws or bolts are shielded, thereby reducing the contact between sludge, sewage, and debris and the installed screws or bolts, making it easier to disassemble the installed screws or bolts.

[0030] The protective bracket body 3 is arranged at the bottom of the bottom shell body 1. Both ends of the protective bracket body 3 are detachably connected to the protective outer shell 2. The protective bracket body 3 is used to protect the bottom of the bottom shell body 1; the protective bracket body 3 can reduce the bumps or scratches on the bottom of the bottom shell body 1, and improve the protection effect of the bottom of the bottom shell body 1. When changing the oil, it is only necessary to remove the protective bracket body 3; and after the bottom shell body 1 is removed, it can be placed on the ground as a bracket of the bottom shell body 1, reducing the wear of the bottom of the bottom shell body 1, and at the same time achieving the effect of protecting the bottom of the bottom shell body 1, effectively improving the service life of the bottom of the bottom shell body 1.

[0031] The sealing gasket body 4 is arranged at the top edge of the bottom shell body 1 and is used for sealing between the bottom shell body 1 and other components after installation. In order to reduce the offset phenomenon of the sealing gasket body 4 when the device and other components are installed, a positioning limit groove 9 is opened at the bottom edge of the bottom shell body 1. The sealing gasket body 4 is located on the inner side of the positioning limit groove 9. The sealing gasket body 4 is positioned and placed by the positioning limit groove 9, and the movement of the sealing gasket body 4 is limited by the positioning limit groove 9.

[0032] Example 2: The automobile engine oil pan provided in Example 1 is further optimized, specifically, as Figure 3-Figure 5 As shown, the reinforcing ribs include a first reinforcing body 11, a second reinforcing body 13, a third reinforcing body 14 and a fourth reinforcing body 15. The first reinforcing body 11 is located at the inner wall of the bottom shell body 1. Several first reinforcing bodies 11 are arranged vertically and parallel on the inner wall of the bottom shell body 1. The second reinforcing body 13 is located on the outside of the bottom shell body 1 and at the lower part of the second cavity. The second reinforcing body 13 is arranged horizontally. The third reinforcing body 14 is located at the bottom of the bottom shell body 1 and at a position corresponding to the bottom of the first cavity. The third reinforcing body 14 is arranged in a mesh shape. The fourth reinforcing body 15 is located on the outside of the bottom shell body 1 and at a position corresponding to the bottom of the second cavity. The fourth reinforcing body 15 is arranged in a mesh shape. The fourth reinforcing body 15 is arranged in a ring shape at a position corresponding to the oil drain port 8.

[0033] Through the above-mentioned structural design, the first reinforcement body 11 on the inner side of the bottom shell body 1 can effectively improve the cavity of the four walls of the bottom shell body 1, reducing the bending phenomenon caused by collision, and the second reinforcement body 13 can improve the strength of the lower part of the second cavity. The third reinforcement body 14 and the fourth reinforcement body 15 can effectively improve the protection of the bottom of the bottom shell body 1, which can effectively reduce the occurrence of thinning of the bottom of the bottom shell body 1 due to wear.

[0034] Example 3: The automobile engine oil pan provided in Example 1 is further optimized, specifically, as Figure 6-Figure 9As shown, the limiting assembly includes a positioning guide groove 16 and a positioning limit member 17. The interior of the protective outer shell 2 is fixedly connected with the positioning guide groove 16, and the outer side of the bottom shell body 1 and the position corresponding to the positioning guide groove 16 are fixedly connected with the positioning limit member 17. The positioning limit member 17 is vertically plugged into the positioning guide groove 16. A limiting through groove 18 connected to the interior of the protective outer shell 2 is provided on the outer side of the protective outer shell 2 and the position corresponding to the positioning guide groove 16. The positioning limit member 17 is snap-fitted into the limiting through groove 18, and both ends of the protective outer shell 2 are fixedly connected; the ends of the protective outer shell 2 are provided with a pick-up and placement grip groove 19, and the outer side of the pick-up and placement grip groove 19 is plugged with a sealing plug-in 28. It can be seen that when the protective outer shell 2 is connected to the bottom shell body 1, the positioning and installation of the protective outer shell 2 and the guiding effect during installation can be achieved through the cooperation of the positioning limit member 17 and the positioning guide groove 16, and the connection limit of the protective outer shell 2 and the bottom shell body 1 can be achieved through the engagement of the positioning limit member 17 and the limiting groove 18, thereby reducing the occurrence of accidental falling off of the protective outer shell 2, and the taking and placing of the protective outer shell 2 is facilitated by the taking and placing grip groove 19. After the protective outer shell 2 is installed, the taking and placing grip groove 19 can be sealed by the sealing plug-in 28 to reduce the intrusion of mud, sewage and debris.

[0035] Furthermore, the positioning limit member 17 includes an elastic member body 20, one side of the elastic member body 20 is fixedly connected to the bottom shell body 1, and a limiting boss 21 is provided on the other side of the elastic member body 20, and the limiting boss 21 is plugged into the limiting groove 18. A fracture 22 is provided on the top of the elastic member body 20, and a spring body 23 is provided inside the elastic member body 20. Both ends of the spring body 23 are connected to the side of the elastic member body 20 close to the bottom shell body 1, and the middle part of the spring body 23 is in contact with the side of the elastic member body 20 away from the bottom shell body 1. Among them, one end of the spring body 23 is fixedly connected to the elastic member 20 by a fixing pin 26, and the other end of the spring body 23 is slidably connected to the elastic member 20 by a sliding pin 27; it can be seen that the fracture 22 opened at the end of the elastic member 20 and the push of the spring body 23 can expand the two sides of the elastic member 20 to both sides. When the protective outer shell 2 and the bottom shell body 1 are installed, the limiting boss 21 can penetrate into the limiting groove 18 to realize the engagement of the positioning limit member 17 with the limiting groove 18. When the protective outer shell 2 needs to be removed, it is only necessary to press the elastic member 20 on the inner side of the limiting groove 18 to move the limiting boss 21 out of the limiting groove 18 to contact the obstruction of the protective outer shell 2, so that the protective outer shell 2 can be moved downward to achieve separation from the bottom shell body 1.

[0036] Furthermore, a limiting stopper 24 is fixedly connected to the interior of the elastic member 20 and at a position below the limiting boss 21. A limiting groove 25 is provided inside the limiting stopper 24, and the middle part of the spring body 23 is located inside the limiting groove 25. It can be seen that when the elastic member 20 is squeezed, the elastic member 20 squeezes the spring body 23, causing one end of the spring body 23 to move and deform the spring body 23, thereby accumulating force in the spring body 23. When the elastic member 20 is no longer squeezed, the spring body 23 releases the accumulated force and pushes the elastic member 20 to reset; in the above process, the spring body 23 is limited by the limiting stopper 24 to avoid the middle part of the spring body 23 from deflecting.

[0037] Example 4: The automobile engine oil pan provided in Example 3 is further optimized, specifically, as follows Figure 10-11 As shown, the sealing plug-in 28 includes a sealing plate body 29, and a connecting plug-in 30 is fixedly connected to one side of the sealing plate body 29. The sealing plate body 29 is plugged into the pick-up and placement grip groove 19 through the connecting plug-in 30. A plurality of limiting buckles 31 are fixedly connected to the outer side of the connecting plug-in 30. The limiting buckles 31 are snap-fitted and connected to the pick-up and placement grip groove 19. The side of the sealing plate body 29 close to the connecting plug-in 30 is in contact with the outer side of the protective outer shell 2, and the side of the sealing plate body 29 away from the protective outer shell 2 is fixedly connected to the pick-up and placement piece 32.

[0038] Through the above-mentioned structural design, when the sealing plug-in 28 is plugged into the pick-up and placement grip groove 19, the sealing plug-in 28 is limited by the limiting buckle 31 and the pick-up and placement grip groove 19, and the sealing plate 29 and the protective outer shell 2 are fitted together to achieve the sealing effect of the pick-up and placement grip groove 19. When the sealing plug-in 28 needs to be removed, it is only necessary to pinch the pick-up and placement piece 32 and pull it out.

[0039] Example 5: The automobile engine oil pan provided in Example 1 is further optimized, specifically, as Figure 12-13 As shown, the protective bracket body 3 includes a side main rod body 33, and the number of the side main rod bodies 33 is two. The two side main rod bodies 33 are arranged in parallel, and the ends of the two side main rod bodies 33 are provided with hooks 34. The ends of the side main rod bodies 33 are plugged into the protective outer shell 2 through the hooks 34, and the outer side of the hooks 34 is provided with an anti-slip sleeve 35. An inner support rod body 36 is arranged in parallel between the two side main rod bodies 33. The number of the inner support rod bodies 36 is several, and the ends and middle parts of the several inner support rod bodies 36 are fixedly connected by a connecting rod body 37. The two ends of the connecting rod body 37 are respectively fixedly connected to the two side main rod bodies 33.

[0040] Through the above structural design, it can be known that debris can be guided by the side main rod body 33 and the inner support rod body 36, reducing direct contact between the debris and the bottom of the bottom shell body 1, thereby improving the service life of the bottom shell body 1, and the connection between the inner support rod body 36 and the side main rod body 33 can be achieved through the connecting rod body 37, and the connection between the end of the side main rod body 33 and the protective outer shell 2 can be achieved through the hook 34.
