Description

Technical Field

[0001] The present application relates to the technical field of automobile parts, and in particular to an oil pan with high sealing performance. Background Art

[0002] The oil pan is a relatively important component in a car engine. When the engine stops running, part of the oil in the engine will return to the oil pan under the action of gravity; when the engine is started, the oil pump will bring the oil to various lubricating parts of the engine.

[0003] An oil storage tank for holding engine oil is provided on one side of the oil pan, and the oil pan is mounted on the lower part of the engine by bolts, and the notch of the oil storage tank is shielded by other components in the engine system. In the related art, in order to improve the sealing performance at the opening of the oil pan oil storage tank, a sealing ring is installed at the notch of the oil pan oil storage tank, and then when the oil pan is installed, the corresponding components and the oil pan press the sealing ring tightly.

[0004] However, since the contact surface between the sealing ring and the oil pan and the corresponding extruded parts is a flat surface, the sealing ring has a weak deformation ability after being extruded, and thus has poor sealing performance. Utility Model Content

[0005] In order to improve the sealing performance of the oil pan, the present application provides an oil pan with high sealing performance.

[0006] The application provides a highly sealed oil pan, which adopts the following technical solution:

[0007] A highly sealed oil pan comprises an oil pan body and a sealing ring, wherein an oil groove for storing engine oil is provided on one side of the oil pan body, the sealing ring is arranged at the notch of the oil groove, the oil groove is located inside the sealing ring, an upper deformation-free ring groove is provided on the side of the sealing ring away from the oil pan body, two upper sealing convex rings are formed on the side of the sealing ring away from the oil pan body through the upper deformation-free ring groove, and the two upper sealing convex rings are arranged at intervals.

[0008] Preferably, arc surfaces are provided on the sides of the two upper sealing convex rings facing away from the oil pan body.

[0009] Preferably, a sealing ring groove for inserting the sealing ring is formed on one side of the oil pan body where the oil tank is formed.

[0010] Preferably, a deformation inclined surface is provided on a side of the sealing ring close to the bottom of the sealing ring groove, and a deformation gap is provided between a groove wall of the sealing ring groove close to the deformation inclined surface and the deformation inclined surface.

[0011] Preferably, a lower deformation clearance ring groove is provided on one side of the sealing ring close to the bottom of the sealing ring groove, and two lower sealing convex rings are formed on one side of the sealing ring close to the bottom of the sealing ring groove through the lower deformation clearance ring groove, and the two lower sealing convex rings are arranged at intervals.

[0012] Preferably, an oil suction pipe is provided in the oil tank, and a pipe sealing gasket ring is provided on the side of the oil suction pipe away from the bottom of the oil tank.

[0013] Preferably, a mounting ring groove for inserting the sealing gasket ring is provided on the oil suction pipe.

[0014] Preferably, the inner wall of the sealing ring is provided with a connecting strip connected to the sealing gasket ring.

[0015] In summary, the present application includes at least one of the following beneficial technical effects:

[0016] 1. The side of the sealing ring facing away from the oil pan forms an uneven plane through the upper deformation groove. After being squeezed, the two upper sealing convex rings will more conveniently deform elastically into the deformation groove to form a better seal. In addition, the two upper sealing convex rings can form a double sealing effect, thereby improving the sealing effect of the oil pan;

[0017] 2. The setting of the deformation slope makes a certain gap between the sealing ring and the groove wall of the sealing ring groove, so that the sealing ring has space for deformation after being squeezed, so that the sealing ring can be better deformed, thereby improving the sealing effect of the sealing ring;

[0018] 3. The setting of the sealing ring also seals the oil suction pipe. When the engine oil enters the oil tank through the oil suction pipe, the oil is not easy to leak under the action of the sealing ring;

[0019] 4. The sealing ring and the sealing gasket ring form a whole through the connecting strip. During installation, the two can be directly installed at the corresponding positions, thereby improving the convenience of installation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following is combined with Figure 1-4 This application is described in further detail.

[0026] The present application embodiment discloses an oil pan with high sealing performance. Figure 1 The oil pan with high sealing performance includes an oil pan body 1 and a sealing ring 2. An oil tank 11 is provided on one side of the oil pan body 1, and part of the engine oil in the engine will be stored in the oil tank 11. The sealing ring 2 is located at the notch of the oil tank 11, and the oil tank 11 is located inside the sealing ring 2. The side of the sealing ring 2 facing away from the oil pan body 1 and the side close to the oil pan body 1 are both concave and convex surfaces, so that the sealing ring 2 can produce better deformation after being squeezed, thereby improving the sealing performance of the sealing ring 2 to the oil pan body 1.

[0027] Reference Figure 1 and Figure 2 An oil suction pipe 12 is integrally formed on the wall of one side of the oil tank 11. The oil in the engine will enter the oil tank 11 through the oil suction pipe 12. A filter is arranged inside the oil suction pipe 12 so that the oil entering the oil tank 11 can be filtered. The opening at one end of the oil suction pipe 12 is in the same direction as the notch of the oil tank 11.

[0028] Reference Figure 1 and Figure 2 A mounting ring groove 13 is provided on the side of the oil suction pipe 12 away from the bottom of the oil groove 11, and a sealing ring 14 is inserted into the mounting ring groove 13. The side of the sealing ring 14 away from the mounting ring groove 13 protrudes from the mounting ring groove 13, so that the sealing ring 14 can be deformed after being squeezed to seal the opening of the oil suction pipe 12.

[0029] Reference Figure 2 and Figure 3 Two connecting strips 15 are integrally formed on the inner wall of the sealing ring 2. The two connecting strips 15 are arranged at intervals. The other ends of the two connecting strips 15 are integrally formed with the sealing gasket ring 14, so that the sealing ring 2 and the sealing gasket ring 14 become a whole and can be installed together during installation. Since the sealing gasket ring 14 is connected to the sealing ring 2 through the connecting strips 15, two notches for the connecting strips 15 to be inserted are provided on the oil suction pipe 12, so that the oil pan body 1 is not easy to be installed due to the excessive protrusion of the connecting strips 15 to generate a gap that affects the sealing effect.

[0030] Reference Figure 1 and Figure 2 A sealing ring groove 16 for inserting the sealing ring 2 is provided on one side of the oil pan body 1 where the oil groove 11 is provided, and a side of the sealing ring 2 facing away from the bottom of the sealing ring groove 16 protrudes out of the sealing ring groove 16, so that the sealing ring 2 can be squeezed and deformed to form a sealing effect during installation of the oil pan body 1.

[0031] Combination Figure 1 Reference Figure 2 and Figure 4 The side of the sealing ring 2 close to the bottom of the sealing ring groove 16 is provided with a deformation slope 21, and the deformation slope 21 gradually extends toward the side close to the groove wall of the sealing ring groove 16 along the direction in which the sealing ring 2 is pulled out of the sealing ring groove 16, that is, the inner edge and the outer edge of the side of the sealing ring 2 close to the bottom of the sealing ring groove 16 are both chamfered. There is a deformation gap between the deformation slope 21 and the groove wall on the corresponding side of the sealing ring groove 16, so that when the sealing ring 2 is squeezed, there is space in the sealing ring groove 16 for deformation.

[0032] Combination Figure 1 Reference Figure 2 and Figure 4 A lower deformation-displacing ring groove 22 is provided on the side of the sealing ring 2 close to the bottom of the sealing ring groove 16. Two lower sealing convex rings 23 are formed on the side of the sealing ring 2 close to the bottom of the sealing ring groove 16 through the lower deformation-displacing ring groove 22. The two lower sealing convex rings 23 are arranged at intervals. The two lower sealing convex rings 23 are provided with arc surfaces on the side close to the bottom of the sealing ring groove 16, so that the lower sealing convex rings 23 are easy to deform after being squeezed. When the sealing ring 2 is squeezed, the two lower sealing convex rings 23 can play a double sealing role, thereby improving the sealing effect of the oil pan body 1.

[0033] Similarly, an upper deformation relief ring groove 24 is provided on the side of the sealing ring 2 away from the lower sealing convex ring 23, and two upper sealing convex rings 25 are formed on the side of the sealing ring 2 away from the oil pan body 1 through the upper deformation relief ring groove 24. The two upper sealing convex rings 25 are arranged at intervals, and the two upper sealing convex rings 25 are provided with arc surfaces on the side away from the oil pan body 1, thereby further improving the sealing effect of the oil pan body 1 after installation.

[0034] The implementation principle of a highly sealed oil pan in the embodiment of the present application is as follows: the side of the sealing ring 2 close to the bottom of the sealing ring groove 16 forms an uneven plane through the lower deformation clearance groove; and the side of the sealing ring 2 away from the oil pan forms an uneven plane through the upper deformation clearance groove. The two lower sealing convex rings 23 and the two upper sealing convex rings 25 are formed so that the sealing ring 2 can form a double sealing effect after being squeezed. In addition, the setting of the deformation slope 21 allows a certain gap between the sealing ring 2 and the groove wall of the sealing ring groove 16, so that the sealing ring 2 has space for deformation after being squeezed, so that the sealing ring 2 can be better deformed, thereby improving the sealing effect of the sealing ring 2.

[0035] 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.
