[0002] As an important part of automobile engines, the background technology of the engine oil pan can be traced back to the early days of the automobile industry. With the continuous development of automobile technology, the design of the engine oil pan has become increasingly mature. As a container for storing engine oil, the oil pan must not only ensure that the engine can be fully lubricated during operation, but also take into account factors such as sealing, corrosion resistance, and convenient maintenance. Modern engine oil pans are made of high-strength materials and have a reasonable structural design to ensure stable operation and long-term durability of the engine.

[0003] The engine oil pan is located at the bottom of the engine. Its main function is to store and supply engine oil. It ensures that all parts of the engine can be fully lubricated when the engine is running at high speed, thereby extending the service life of the engine. The oil pan usually has a well-sealed interface to prevent oil leakage. In addition, in order to facilitate maintenance and oil replacement, the oil pan is also equipped with components such as drain bolts.

[0004] Especially when unscrewing the drain bolt, the oil will often flow out directly, easily staining the maintenance personnel's clothes. At the same time, in the long-term use of the engine oil pan, some impurities will inevitably accumulate. These impurities mainly come from the oxidation of the oil, the precipitation of combustion products, and metal particles generated by the internal wear of the engine. These impurities mixed in the oil will reduce the lubrication performance and reduce the wear life of the engine, so the oil needs to be replaced. Utility Model Content

[0005] The utility model aims to provide an engine oil pan, which is less likely to contaminate the clothes of maintenance personnel when draining the engine oil, and can also effectively reduce the frequency of changing the engine oil.

[0006] In order to solve the above technical problems, the utility model provides an engine oil pan, including an oil pan with an upper opening, a mounting edge is provided at the edge of the upper end of the oil pan, a plurality of mounting holes are provided through the mounting edge, the oil pan includes a shallow box portion and a deep box portion that are interconnected, the depth of the deep box portion is deeper than the depth of the shallow box portion, a collecting inclined baffle plate that is inclined downward in a direction away from the shallow box portion is provided in the deep box portion, the collecting inclined baffle plate has a side away from the shallow box portion, and the other sides are connected to the inner wall of the deep box portion, and there is a gap between the side of the collecting inclined baffle plate away from the shallow box portion and the inner wall of the deep box portion;

[0007] An oil drain hole is opened through the bottom of the deep box portion, and the oil drain hole is connected to an oil drain pipe downwardly. A threaded connection sleeve is provided inwardly on the side wall of the deep box portion facing the oil drain hole, and an oil drain bolt is threadedly connected to the threaded connection sleeve. The oil drain bolt protrudes outwardly from the threaded connection sleeve and is provided with a bolt head. A blocking shaft for blocking the oil drain hole is provided at one end of the oil drain bolt away from the bolt head.

[0008] The utility model is further configured that the impurity collecting inclined baffle is a mesh plate.

[0009] The utility model is further configured that a vertically arranged oil stabilizing baffle is arranged at the upper end of the impurity collecting inclined baffle in the deep box portion, and a gap is provided between the lower side of the oil stabilizing baffle and the impurity collecting inclined baffle.

[0010] The utility model is further configured that the oil stabilizing baffle is a mesh plate.

[0011] The utility model is further configured that the lower end of the oil drain pipe is detachably connected with a dustproof sealing plug.

[0012] The utility model is further configured such that the inner wall of the oil drain hole covers more than half of the cross section of the hole blocking shaft.

[0013] The utility model is further configured that the hole blocking shaft is made of rubber material.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] Firstly, the utility model seals the oil drain hole by using a plugging shaft connected to the oil drain bolt, and drains the engine oil through the oil drain pipe connected to the oil drain hole. When draining the engine oil, the oil drain bolt pulls the plugging shaft to move and open the oil drain hole, and the engine oil flows out along the oil drain pipe. The engine oil can be caught in the pipe in advance with a container, so that the engine oil will not flow out along the oil drain bolt, and it is not easy to contaminate the clothes of the maintenance personnel.

[0016] Secondly, the utility model sets the inclined impurity collecting inclined baffle plate, and the impurities in the engine oil will flow along the impurity collecting inclined baffle plate and collect from the bottom of the deep box portion to the bottom of the deep box portion. When the engine oil oscillates, the impurities are not easy to enter the clean engine oil again due to the obstruction of the impurity collecting inclined baffle plate, which can effectively reduce the frequency of engine oil replacement;

[0017] Thirdly, by setting the mesh holes of the oil stabilizing baffle and the inclined baffle to collect impurities, the oil surface is vibrated and splashed, which is beneficial to the precipitation of impurities in the engine oil. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Example, see Figure 1-3 An engine oil pan, including an oil pan with an upper opening, a circle of mounting edges 1 is arranged on the edge of the upper end of the oil pan, and a plurality of mounting holes 2 are arranged through the mounting edges 1. The oil pan includes a shallow box portion 3 and a deep box portion 4 which are connected to each other, and the depth of the deep box portion 4 is deeper than the depth of the shallow box portion 3. A collection inclined baffle 5 which is inclined downward in a direction away from the shallow box portion 3 is arranged in the deep box portion 4. The collection inclined baffle 5 is a mesh plate. Except for one side away from the shallow box portion 3, the other sides of the collection inclined baffle 5 are connected to the inner wall of the deep box portion 4. There is a gap between the side of the collection inclined baffle 5 away from the shallow box portion 3 and the inner wall of the deep box portion 4, so that the impurities in the engine oil gradually slide down to the bottom of the deep box portion 4 along the collection inclined baffle 5, and the impurities are not easy to enter the engine oil upward through the obstruction of the collection inclined baffle 5. Three vertically arranged oil stabilizing baffles 6 are arranged at the upper end of the impurity collecting inclined baffle 5 in the deep box portion 4. The oil stabilizing baffles 6 are mesh plates. When the oil pan shakes, the oil stabilizing baffles 6 can prevent the oil surface from vibrating and splashing caused by the engine bumps, which is conducive to the precipitation of impurities in the engine oil.

[0024] An oil drain hole 7 is provided through the bottom of the deep box 4, and an oil drain pipe 8 is connected downwardly to the oil drain hole 7. In order to prevent dust from entering and blocking the oil drain pipe 8 during long-term use, a dustproof sealing plug 9 is detachably connected to the lower end of the oil drain pipe 8. A threaded connection sleeve 10 facing the oil drain hole 7 is provided inwardly on the side wall of the deep box 4, and an oil drain bolt 11 is threadedly connected to the threaded connection sleeve 10.
