[0022] The technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0023] AsFigs. 1-2 The utility model discloses a technical scheme as follows: An oil pan structure of an engine, comprising an oil pan 1, and a filter screen 4 detachably installed in the inside of the oil pan 1. The bottom surface of the inner cavity of the oil pan 1 is in a stepped shape, and the filter screen 4 is located on the transition surfaces at the uppermost and lowermost positions of the inner bottom surface of the oil pan 1.

[0024] The transition surfaces at the uppermost and lowermost positions of the inner bottom surface of the oil pan 1 are inclined surfaces with a curvature, and the filter screen 4 is fixedly installed on the inclined surfaces. After a period of use, the filter screen 4 can be disassembled, replaced, or cleaned.

[0025] The cavity at the uppermost position of the inner bottom surface of the oil pan 1 is a drip chamber 7, and the cavity at the lowermost position of the inner bottom surface of the oil pan 1 is an oil storage chamber 5. The oil on the engine falls into the drip chamber 7 and then flows into the oil storage chamber 5 through the transition surfaces at the filter screen 4. Since the engine oil after lubrication of the engine is mixed with metal powder and impurities generated by wear of engine parts, the filter screen 4 filters the engine oil to remove the impurities.

[0026] The bottom surface of the drip chamber 7 is inclined, and gradually inclines downward from one end far away from the oil storage chamber 5 to one end close to the oil storage chamber 5. This facilitates the better flow of the engine oil into the oil storage chamber 5.

[0027] A plurality of flow guide plates 8 are fixedly connected to the bottom surface of the drip chamber 7 at intervals, the flow guide plates 8 are arranged along the inclination direction of the bottom surface of the drip chamber 7, and the cross-sectional shape of the flow guide plates 8 is triangular. The side surfaces of the flow guide plates 8 are all inclined surfaces, so that the engine oil falling on the flow guide plates 8 converges together along the inclined surfaces of the flow guide plates 8, shortening the time of the engine oil collection.

[0028] A baffle plate 6 is fixedly connected to the bottom surface of the oil storage chamber 5, and the baffle plate 6 is inclined. The baffle plate 6 generates resistance to the shaking of the engine oil, making the engine oil more stable.

[0029] A plurality of heat dissipation grooves 9 are provided on the bottom surface of the oil pan 1 at intervals, and the plurality of heat dissipation grooves 9 cooperatively form a sawtooth shape. This increases the area of the bottom surface of the oil pan 1, thereby increasing the contact surface with air and improving the heat dissipation effect.

[0030] The bottom surface of the oil pan 1 is made of aluminum. Aluminum has good thermal conductivity and light weight, and is one of the most widely used heat dissipation materials.

[0031] A ring-shaped fixed plate 2 is fixedly connected to the top end of the oil pan 1, and a plurality of mounting holes 3 are uniformly provided on the fixed plate 2. The oil pan 1 is fixed on the engine by using bolts through the mounting holes 3.

[0032] Working principle:

[0033] Bolts are used to fix the fixed plate 2 on the engine through the mounting holes 3, and then the oil pan 1 is installed.

[0034] The oil on the engine drips into the drip chamber 7 and onto the deflector 8. The oil runs down the slope of the deflector 8 and collects together before being filtered by the filter 4 and then flowing into the reservoir 5. The oil in the reservoir 5 can then be pumped out and used to continue lubricating the engine.

[0035] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to some of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
