Problems solved by technology

During the use of the engine, the oil level in the oil pan gradually decreases. If the oil quantity is insufficient or the engine tilt angle is too large, it is easy to cause insufficient oil supply from the oil pump and cause the lubrication system to work abnormally, affecting the lubrication of lubricating parts such as engine bushings. service life, and even cause engine damage

Embodiment 1

[0052] This embodiment provides an oil pan liquid level regulating device 1 for an engine oil pan 211 .

[0053] Such as Figure 1 to Figure 3 As shown, the oil pan liquid level regulating device 1 includes an air charging cavity 11 and an intake and exhaust assembly 12 . The air-filled cavity 11 is disposed in the engine oil pan 211 , and when the engine oil pan 211 contains oil, the outer wall of the air-filled cavity 11 can be in contact with the engine oil. At least part of the structure of the inflatable cavity 11 can be expanded and deformed. The intake and exhaust assembly 12 communicates with the inside of the inflatable cavity 11, and the intake and exhaust assembly 12 can supply air to the inflatable cavity 11 to expand the volume of the inflatable cavity 11 (such as figure 2 state shown); the inflatable cavity 11 can also be exhausted outwards through the intake and exhaust assembly 12, so that the volume of the inflatable cavity 11 can shrink (as figure 1 statu...

Embodiment 2

[0057] This embodiment provides an oil pan liquid level regulating device 1, which is further improved on the basis of the first embodiment.

[0058] Such as image 3 As shown, at least part of the structure of the inflatable cavity 11 is an elastic member 111. When the inflatable cavity 11 is inflated by the intake and exhaust assembly 12, the elastic member 111 expands outward under the pressure of the gas in the inflatable cavity 11. , through the elastic deformation of the elastic member 111, the overall volume of the air-filled cavity 11 is changed, thereby reducing the space in the engine oil pan 211 that can accommodate the engine oil, and squeezing the engine oil in the engine oil pan 211, so that the oil level rises , to adjust the oil level. Wherein, the elastic member 111 may be an elastic film, such as a rubber film, which has a simple structure and is easy to implement.

Embodiment 3

[0060] This embodiment provides an oil pan liquid level regulating device 1, which is further improved on the basis of the second embodiment.

[0061] Such as Figure 4 with Figure 5 As shown, the oil pan liquid level regulating device 1 also includes an oil liquid cavity 13, which is arranged in the engine oil pan 211 and used to provide a storage space for spare oil. The oil cavity 13 is provided with an overflow hole 131, the overflow hole 131 communicates with the inside of the oil cavity 13 and the engine oil pan 211, and the distance from the overflow hole 131 to the bottom plate of the oil cavity 13 is not less than the distance threshold , that is, the overflow hole 131 has a certain height, so that the part of the oil chamber 13 below the overflow hole 131 can store engine oil.

[0062] The side plate 112 of the inflatable cavity 11 is provided with an elastic member 111 , and the oil chamber 13 is connected with the side plate 112 provided with the elastic member ...

Abstract

The invention provides an oil pan liquid-level adjusting device, an engine and a vehicle. The oil pan liquid-level adjusting device comprises an air inflation cavity formed in an oil pan of the engineand an air inlet and outlet assembly communicating with the air inflation cavity; and the air inflation cavity achieves air inflation expansion or air exhausting retracting through the air inlet andoutlet assembly so as to adjust the liquid level of engine oil in the oil pan of the engine through the volume change of the air inflation cavity. According to the technical scheme, when the liquid level of the engine oil in the oil pan of the engine is low, the liquid level of the engine oil can be adjusted by changing the volume of the air inflation cavity, the influence of lowering of the liquid level of the engine oil on an engine lubricating system can be effectively prevented, and the service life of an engine lubricating part is prolonged advantageously to prevent the engine from beingdamaged.

Description

technical field [0001] The present application relates to the technical field of engine auxiliary equipment, in particular, to an oil pan regulating device, an engine and a vehicle. Background technique [0002] The engine oil pan is located at the bottom of the crankcase of the engine. It is used to store and collect the returning engine oil to prevent impurities from entering the engine's lubrication system. It also has the function of cooling the engine oil and preventing the oil from oxidizing. In order to ensure that the lubrication system of the engine can work normally, the oil level in the engine oil pan must be kept at a certain height. During the use of the engine, the oil level in the oil pan gradually decreases. If the oil quantity is insufficient or the engine tilt angle is too large, it is easy to cause insufficient oil supply from the oil pump and cause the lubrication system to work abnormally, affecting the lubrication of lubricating parts such as engine bus...
