[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0023] like Figure 1-Figure 3 As shown, an embodiment of the utility model provides a composite oil pan for a large engine, comprising an oil pan body 1, an oil pan end face 10 is arranged on the surface of the oil pan body 1, and a plurality of fixing holes are opened on the surface of the oil pan end face 10, and a metal bushing 8 is arranged inside the fixing hole;

[0024] An annular mounting groove 11 is provided on the surface of the oil pan end face 10, and a rubber sealing ring 9 matching the shape of the mounting groove 11 is provided inside the mounting groove 11;

[0025] A plurality of first internal protrusion structures 5 are disposed on one side of the oil pan body 1, and a plurality of second internal protrusion structures 7 are disposed on the other side of the oil pan body 1;

[0026] A plurality of external protruding structures 2 are provided on both sides of the surface of the oil pan body 1 .

[0027] In one embodiment of the utility model, by providing a plurality of groups of external protruding structures 2 on the outer surface of the oil pan body 1, the overall capacity of the oil pan body 1 can be increased on the one hand, and the overall strength of the oil pan body 1 can be increased on the other hand, so as to ensure that the oil pan body 1 can still maintain a stable dimension after endurance creep.

[0028] The first internal protrusion structure 5 and the second internal protrusion structure 7 arranged inside the oil pan main body 1 are distributed on the inner wall of the oil pan main body 1 in a longitudinal and transverse state respectively, and the first internal protrusion structure 5 and the second internal protrusion structure 7 can not only increase the overall strength of the oil pan main body 1 and improve the modal, but also can reduce the noise of the oil pan main body 1 during use.

[0029] In this embodiment, external reinforcing ribs 3 are provided on one side of the outer surface of the oil pan main body 1, and the external reinforcing ribs 3 are distributed in a mesh shape on the outer surface of the oil pan main body 1, and external reinforcing ribs 6 are provided on the other side of the outer surface of the oil pan main body 1. Internal reinforcing ribs 4 are provided inside the oil pan main body 1. This orderly arrangement of reinforcing ribs can greatly improve the overall strength of the oil pan main body 1 and reduce stress.

[0030] In this embodiment, a bolt installation reserved area is provided between two adjacent external protruding structures 2, so that space can be reserved for bolt installation, and there is no need to separately provide a bolt installation space, thereby improving the integration level of the oil pan.

[0031] In this embodiment, the top end of the metal bushing 8 protrudes from the surface of the oil pan end face 10 by 0.5 mm. Through this protruding bushing design, after the bolts are installed, the bolts are directly subjected to force on the surface of the metal bushing 8 instead of the oil pan end face 10, thereby preventing the oil pan from experiencing durable creep and dimensional changes that affect sealing technology problems.

[0032] In this embodiment, the structure of the rubber sealing ring 9 consists of two sealing ribs on the top and one sealing rib on the bottom, so that the sealing effect of the rubber sealing ring 9 can be improved.

[0033] In this embodiment, a double-card point structure is provided at the top of the installation groove 11, and the rubber sealing ring 9 is stably assembled inside the installation groove 11 through the double-card point structure;

[0034] The design of the double-card point structure can not only ensure that the rubber sealing ring 9 will not fall off during the production process, packaging process and transportation process after installation, but also ensure that the rubber sealing ring 9 will not fall over after installation. In addition, during the extrusion installation process of installing the oil pan on the engine cylinder block, even if the rubber sealing ring 9 is squeezed vertically, the rubber sealing ring 9 will not shake left and right, resulting in an unqualified compression rate of the sealing ring.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
