Description

Technical Field

[0001] The utility model relates to the technical field of automobiles and engineering machinery equipment, and in particular to an oil pan protection structure. Background Art

[0002] The information disclosed in the background technology of the present invention is only intended to increase the understanding of the overall background of the present invention, and shall not necessarily be regarded as an admission or suggestion in any form that the information constitutes the prior art already known to those skilled in the art.

[0003] As an important part of the bottom of the engine, the oil pan is not only used to store engine oil, but also plays a role in protecting the engine. With the development of the automobile industry and the advancement of technology, the protection requirements for the oil pan are becoming higher and higher. Especially in harsh road conditions, how to effectively prevent the oil pan from being damaged has become an urgent problem to be solved.

[0004] In the prior art, most oil pans are made of metal (such as steel or aluminum) or plastic materials. Although these materials have a certain toughness, they may still break under extreme temperatures or when subjected to strong impact. Moreover, they may crack during long-term use due to heat, mechanical stress and stress corrosion.

[0005] In the prior art, the oil pan is designed with reinforcing ribs, however, the common design of the reinforcing rib structure cannot achieve a good effect and may also cause resonance during operation, thereby increasing mechanical stress.

[0006] Although a guard plate is provided in the prior art to prevent the oil pan from being hit or scratched by foreign objects on the road, in actual applications, when the guard plate is severely impacted, the force will be transferred to the oil pan, which will still cause damage to the oil pan.

[0007] Therefore, it is necessary to design an oil pan protection structure with high strength and good resistance. Utility Model Content

[0008] In order to solve the above technical problems, the utility model provides an oil pan protection structure, which is intended to strengthen the strength of the oil pan and provide good resistance to mechanical stress and the vibration generated therefrom as well as impact and friction with the ground.

[0009] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0010] An oil pan protection structure comprises an oil pan body, wherein at least one unit reinforcement rib is arranged at the bottom of the oil pan body;

[0011] The unit reinforcement ribs include a central ring reinforcement rib arranged at the center of the outer side of the bottom of the oil pan body, a plurality of peripheral ring reinforcement ribs are arranged layer by layer around the central ring reinforcement ribs, a plurality of trunk reinforcement ribs extend from the central ring reinforcement ribs to the peripheral ring reinforcement ribs, and the central ring reinforcement ribs, the peripheral ring reinforcement ribs and the trunk reinforcement ribs form a spider web shape;

[0012] A plurality of groups of branch-shaped reinforcing ribs are provided on both sides of the trunk-shaped reinforcing ribs extending outwards, and the trunk-shaped reinforcing ribs and the branch-shaped reinforcing ribs form a branch-trunk shape.

[0013] Preferably, a frame is provided at the bottom of the oil pan body, and the end of the stem-shaped reinforcement rib is integrally connected to the frame.

[0014] Preferably, the branch-shaped reinforcement ribs are integrally connected with the corresponding outer ring reinforcement ribs.

[0015] Preferably, the branch-like reinforcing ribs outside the outermost outer ring reinforcing ribs are connected as one body with the frame.

[0016] Preferably, the rectangular oil pan body is provided with more than two cross-connected unit reinforcement ribs.

[0017] Preferably, the distance between two adjacent outer ring reinforcement ribs increases from inside to outside.

[0018] Preferably, the central ring reinforcement ribs, the outer ring reinforcement ribs, the trunk reinforcement ribs, the branch reinforcement ribs and the frame are all integrally formed with the oil pan body.

[0019] The utility model includes but is not limited to the following beneficial effects:

[0020] In the utility model, the design of the spider-web-like reinforcement ribs can evenly disperse the force applied to the entire oil pan, avoiding local stress concentration and reducing the risk of cracking due to excessive local stress; the branch-like reinforcement ribs further disperse the force from the center to the surroundings, similar to the role of tree roots, and can more effectively transmit the force to every corner of the oil pan, reducing excessive local force; the two work together to greatly enhance the stress dispersion effect.

[0021] In the utility model, the network structure formed by the spider-web-like reinforcement ribs and the branch-like reinforcement ribs can work together to effectively absorb and disperse vibration energy, enhance the vibration suppression effect, reduce the additional stress caused by resonance, and reduce fatigue damage caused by vibration.

[0022] In the utility model, spider-web-like reinforcement ribs and branch-like reinforcement ribs are combined to form a composite structure, which enhances the overall rigidity of the oil pan, improves its ability to resist deformation and friction, improves its shape stability when subjected to impact, and reduces deformation caused by impact.

[0023] In the present invention, by adjusting the layout and density of the reinforcing ribs, optimization can be performed according to different application scenarios and vehicle types to meet protection requirements under specific conditions. BRIEF DESCRIPTION OF THE DRAWINGS
