Example 1

The embodiment relates to an engine oil storage structure and provides an oil storage device with an oil-gas separation function for an engine; an exemplary structure thereof is shown in fig. 1 to 4.

In general, the engine oil storage structure comprises a tank body 1 and an oil-gas separation unit arranged in the tank body 1. The top of the tank body 1 is provided with an exhaust port 12, the bottom of the tank body 1 is provided with an oil outlet 14, and the tank body 1 is provided with an oil inlet 13; the engine oil containing gas entering the tank body 1 from the oil inlet 13 passes through the oil-gas separation unit, the gas is separated by the oil-gas separation unit and then discharged from the exhaust port 12, and the engine oil falls down after being separated by the oil-gas separation unit and is discharged from the oil outlet 14.

Specifically, as shown in fig. 5, the tank 1 of the present embodiment includes a main housing 10 and a bottom case 11 integrally connected, a main chamber 100 is formed inside the main housing 10, an oil accumulation chamber 110 is formed inside the bottom case 11, and the main chamber 100 and the oil accumulation chamber 110 communicate up and down. Based on the above arrangement structure, the exhaust port 12 of the present embodiment is disposed at the top of the main housing 10, and the oil outlet 14 is disposed at the bottom of the bottom housing 11; the oil-gas separation unit is disposed at the upper part of the main chamber 100 or at the exhaust port 12, and of course, the oil-gas separation unit may be disposed at the upper part of the main chamber 100 and at the exhaust port 12.

The tank body 1 is designed into a main shell 10 and a bottom shell 11, so that a main cavity 100 and an oil accumulation cavity 110 which are communicated up and down can be formed in the tank body 1; the oil-gas separation unit is arranged at the upper part of the main cavity 100 or at the exhaust port 12 and other areas, separated engine oil falls into the oil accumulation cavity 110 from the main cavity 100 and is discharged from the oil outlet 14, so that the functional partition inside the tank body 1 is realized, and the oil-gas separation effect of the engine oil storage structure is better exerted.

As can be seen from fig. 5 or 4, the main housing 10 of the present embodiment has a bottom wall located outside the bottom shell 11, and the oil inlet 13 is provided on the bottom wall. As shown in fig. 6 and 7, the oil-gas separation unit of the present embodiment includes an oil distribution pipe 3 provided in a main chamber 100. And the oil distribution pipe 3 includes a main pipe 300 extending upward from the oil inlet 13 to the top of the main pipe 100, and a plurality of oil distribution pipes 301 communicating with the top end of the main pipe 300. The oil inlet 13 is arranged on the bottom wall of the main shell 10, and engine oil entering the tank body 1 flows into the top of the main cavity 100 from bottom to top through the main pipe 300 and is dispersed through the oil distributing pipe 301; such a design facilitates the separation of air bubbles from the oil.

Of course, the specific arrangement, number, etc. of the oil distribution pipes 301 can be flexibly designed. In this embodiment, the main housing 10 has a cylindrical shape, the top end of the main tube 300 is located on the axis of the main housing 10, and the oil distribution tubes 301 are arranged in a divergent shape with the top end of the main tube 300 as the center. Meanwhile, each of the oil distribution pipes 301 is preferably in an upward-inclined arrangement in the radial direction of the main casing 10. Preferably, the sum of the flow areas of the oil distribution pipes 301 is larger than the flow area of the main pipe 300; the flow area of each oil distribution pipe 301 is smaller than the flow area of main pipe 300.

Each oil distributing pipe 301 adopts a divergent layout and an upward inclined arrangement mode, so that oil-gas separation of engine oil containing gas flowing out from the port of the oil distributing pipe 301 is facilitated. Specifically, the inner diameter of main pipe 300 may be 25mm, and six equal-diameter oil distribution pipes 301 may be provided, each of which has an inner diameter of 12mm. The design adopts a method of reducing and increasing the flow rate, so that the gas in the engine oil can be effectively separated, and the gas content of the engine oil can be reduced. It should be noted that the sum of the flow areas of the respective oil distribution pipes 301 in the dispersed structure is larger than the flow area of the main pipe 300; while ensuring that the oil distribution pipes 301 are arranged obliquely upwards, the inclination of the oil distribution pipes 301 is preferably set to be uniform, and the oil distribution pipes 301 are uniformly distributed at intervals, so that the engine oil sprayed out of the oil distribution pipes 301 is not interfered with each other, and the possibility of mixing in the engine oil in the falling process is reduced.

In addition, as shown in fig. 7 and in combination with fig. 5, the oil-gas separation unit of the present embodiment further includes a horn-shaped oil baffle plate 4 disposed in the main chamber 100, wherein the horn mouth of the oil baffle plate 4 is disposed downward, the main pipe 300 penetrates through the oil baffle plate 4 from bottom to top, and the ports of each oil distributing pipe 301 are located above the oil baffle plate 4. The oil baffle plate 4 in a horn mouth shape is arranged below each oil distributing pipe 301, and falling engine oil can firstly fall on the oil baffle plate 4, so that the falling speed is reduced, and bubbles generated by impact of the falling splashing engine oil on the liquid level are prevented.

In addition to the above-described oil-gas separation parts, the oil-gas separation unit of the present embodiment further includes an oil-gas separator 2 provided at the exhaust port 12. The oil-gas separator 2 is arranged at the air outlet 12, so that engine oil in the tank body 1 can be effectively prevented from splashing outside the tank body 1 from the air outlet 12, and air separated from the top of the main cavity 100 can be smoothly discharged through the air outlet 12.

In addition, in the engine oil storage structure of the present embodiment, an oil drain port 15 may be provided at the bottom of the bottom case 11, and a plug screw for blocking the oil drain port 15 may be provided at the oil drain port 15. A filter screen 5 may be further disposed in the oil accumulation chamber 110, so that the engine oil in the main chamber 100 passes through the filter screen 5 and reaches the oil outlet 14.

An oil drain port 15 is arranged at the bottom of the bottom shell 11, so that an engine oil storage structure can be cleaned conveniently, and accumulated oil and impurities in the tank body 1 can be thoroughly discharged during overhaul. The filter screen 5 is arranged in the oil accumulation cavity 110, so that the configuration of an engine oil collector can be omitted, and the configuration quantity of parts is reduced by collecting the engine oil from the cavity 100 into the oil accumulation cavity 110 while filtering impurities in the engine oil through one filter screen 5.

Meanwhile, it should be noted that the oil outlet 14 and the oil drain port 15 are both arranged at the bottom of the tank body 1, which is favorable for establishing the oil pressure of the return oil, and the oil in the tank body 1 can be accumulated in the oil accumulation cavity 110 by gravity and further drained from the oil outlet 14 or the oil drain port 15; when the bottom case 11 is disposed at a height higher than that of the engine, the engine oil in the oil accumulation chamber 110 may flow back into the engine by gravity; of course, an oil pump may be provided in the oil accumulation chamber 110, and the oil in the oil accumulation chamber 110 may be pressurized by the oil pump to flow back into the engine through the oil outlet 14. When the filter screen 5 is arranged, the distance between the filter screen 5 and the oil outlet 14 is preferably pulled away, so that the probability of impurities entering the oil pump or reaching the oil outlet 14 is reduced.

In summary, in the engine oil storage structure of the present embodiment, the exhaust port 12 is provided at the top of the tank 1 of the engine oil storage structure, and the oil-gas separation unit is provided in the tank 1, so that after the engine oil conveyed from the oil pan of the engine enters the tank 1, the gas mixed in the engine oil can be separated by the oil-gas separation unit, the separated gas can be discharged from the exhaust port 12 to the outside of the tank 1, and the engine oil after oil-gas separation can be returned from the oil outlet 14 to the engine for use; thus providing an oil storage device for an engine with oil-gas separation.

Example two

The present embodiment relates to a vehicle provided with an engine; meanwhile, the engine is provided with the engine oil storage structure provided in the first embodiment.

Of course, a plug screw for the circulation of oil should be provided between the engine and the tank 1, in particular, the plug screw comprises an oil drain pipe and an oil return pipe. The oil discharge pipe is communicated between the oil inlet 13 and an oil pan of the engine and used for conveying engine oil in the oil pan into the tank body 1; the oil return pipe is communicated between the oil outlet 14 and the housing of the engine to return the engine oil in the tank 1 to the housing.

By providing the engine oil storage structure for the engine, the dry oil pan of the engine in a lower chassis vehicle type can cope with the situation that the engine oil cannot be stored. In addition, the engine oil storage structure has a certain oil-gas separation function, and can effectively remove gas mixed in engine oil, so that the lubricating effect of the engine oil on movable parts in the engine is improved.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
