DETAILED DESCRIPTION

[0029] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided to make the present invention more comprehensive and complete and to fully convey the concepts of example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted.

[0030] The words expressing positions and directions described in the present utility model are all explained by taking the drawings as examples, but they can be changed as needed, and all the changes are included in the protection scope of the present utility model.

[0031] like Figure 1 and Figure 2 As shown, the utility model provides an oil-gas separator 100 , including a housing 1 , an oil-gas separation unit 2 and a driving member 3 .

[0032] The interior of the housing 1 is hollow and forms a containing chamber 11. The housing 1 also includes an inlet 12 and an outlet 13. The inlet 12 and the outlet 13 are used to connect the containing chamber 11 and the external space of the oil-gas separator 100 respectively. The inlet 12 can be used to access the mixed gas from the outside so that the mixed gas from the outside can flow into the containing chamber 11 through the inlet 12; for example, the inlet 12 is connected to the crankcase of the engine to access the mixed gas in the crankcase. The outlet 13 is arranged below the containing chamber 11. The mixed gas is separated into two parts, oil and separated gas, after oil and gas separation. The oil and separated gas can be discharged from the oil-gas separator 100 through the outlet 13. Among them, the housing 1 can be placed horizontally, and the containing chamber 11 in the housing 1 can be extended in the horizontal direction. The outlet 13 and the inlet 12 are distributed at opposite ends of the containing chamber 11 in the horizontal direction, and the outlet 13 and the inlet 12 can be respectively located below the containing chamber 11.

[0033] In some specific embodiments, the housing 1 includes a main body 14 and a mounting seat 15, and the main body 14 and the mounting seat 15 may be an integrated structure. The main body 14 is hollow inside and forms a receiving cavity 11, and the main body 14 may be placed horizontally, that is, the axis of the main body 14 is arranged horizontally. The mounting seat 15 is arranged below the main body 14 and is used to support the main body 14, and the mounting seat 15 is provided with an inlet 12 and an outlet 13 connected to the receiving cavity 11, and the mounting seat 15 may be a plate-like structure, and the mounting seat 15 may also be in a horizontal manner, for example, the upper and lower end surfaces of the mounting seat 15 are respectively parallel to the horizontal plane.

[0034] The oil-gas separation unit 2 is accommodated in the accommodating chamber 11, and the oil-gas separation unit 2 is used to separate the oil and gas of the mixed gas to obtain oil and separated gas. After the mixed gas flows into the accommodating chamber 11 from the inlet 12 of the shell 1, it will flow to the oil-gas separation unit 2, and the oil-gas separation unit 2 will separate the oil and gas in the mixed gas. The oil and separated gas obtained after separation are discharged through the outlet 13 of the shell 1. Among them, the oil-gas separation unit 2 can be a centrifugal oil-gas separator, and the oil-gas separation unit 2 includes a rotating shaft 21 and a plurality of laminations 22 sleeved on the rotating shaft 21. The plurality of laminations 22 are arranged at intervals. The rotating shaft 21 can be connected to the driving member 3 and rotate under the drive of the driving member 3, thereby driving the laminations 22 to rotate. When the mixed gas flows to the oil-gas separation unit 2, the mixed gas flows outward through the gap between adjacent laminations 22, and at the same time, the oil and gas in the mixed gas are separated under the action of centrifugal force.

[0035] The existing oil-gas separator needs to be provided with an air inlet for receiving the mixed gas, an air outlet for discharging the separated gas, and an oil outlet for discharging the separated oil. The air inlet, air outlet, and oil outlet of the existing oil-gas separator need to be provided with connection structures respectively when they need to be connected with external components, resulting in a relatively complex structure of the oil-gas separator and a relatively complex connection method between the oil-gas separator and the external components. In the present application, the outlet 13 is provided below the accommodating chamber 11, and the separated oil and separated gas can be discharged through the outlet 13. The oil obtained after separation can fall into the engine by its own weight for reuse, and the separated gas obtained after separation is discharged to the desired position through an external guide structure. That is, the present application simplifies the structure of the oil-gas separator 100 by providing an outlet 13 to discharge the separated oil and gas, and also simplifies the connection method when the oil-gas separator 100 is connected with external components.

[0036] The driving member 3 includes a body 32 and a rotating shaft 31. The body 32 is used to drive the rotating shaft 31 to rotate. The rotating shaft 31 is connected to the oil-gas separation unit 2 to drive the oil-gas separation unit 2 to rotate, so that the oil-gas separation unit 2 separates the mixed gas into oil and gas through centrifugal action. Specifically, the driving member 3 can be a driving motor, the rotating shaft 31 of the driving member 3 is the output shaft of the driving motor, and the body 32 of the driving member 3 can be the part of the driving motor except the output shaft.

[0037] In some specific embodiments, the body 32 of the driving member 3 is disposed outside the housing 1 and fixedly connected to the housing 1. For example, the body 32 of the driving member 3 is disposed on a side of the housing 1 adjacent to the outlet 13 along the extension direction of the accommodating chamber 11, and the body 32 of the driving member 3 is screwed to the housing 1. The rotating shaft 31 of the driving member 3 may pass through the housing 1 and extend into the accommodating chamber 11 to be directly connected to the oil-gas separation unit 2 located in the accommodating chamber 11. For example, the rotating shaft 31 of the driving member 3 is directly connected to the rotating shaft 21 of the oil-gas separation unit 2.

[0038] In the existing oil-gas separator 100, the driving member 3 and the oil-gas separation unit 2 are connected by a transmission mechanism such as a gear set, which results in a low transmission efficiency between the driving member 3 and the oil-gas separation unit 2. In the present application, the rotating shaft 31 of the driving member 3 is directly connected to the oil-gas separation unit 2, which can avoid the loss of transmission efficiency between the driving member 3 and the oil-gas separation unit 2 caused by the transmission mechanism, thereby improving the transmission efficiency between the driving member 3 and the oil-gas separation unit 2. In the present application, there is no need to set a transmission mechanism between the driving member 3 and the oil-gas separation unit 2, which can simplify the structure of the oil-gas separator 100.

[0039] Reference Figures 3 to 5 The utility model further provides an oil-gas separation assembly, including the above-mentioned oil-gas separator 100 and cylinder head cover 200, and may also include a guide plate 300.

[0040] The oil-gas separator 100 is mounted on the outer surface of the cylinder head cover 200, and the inlet 12 of the oil-gas separator 100 is connected to the inside of the cylinder head cover 200, so that the mixed gas inside the cylinder head cover 200 can flow into the accommodating chamber 11 of the oil-gas separator 100 through the inlet 12. The outlet 13 of the oil-gas separator 100 can be connected to the inside of the cylinder head cover 200, so that the oil obtained after separation can flow from the outlet 13 into the cylinder head cover 200 for reuse. Specifically, the mounting seat 15 of the housing 1 in the oil-gas separator 100 abuts against the outer surface of the cylinder head cover 200, and the mounting seat 15 of the housing 1 is fixedly connected to the cylinder head cover 200 by screws. Among them, the cylinder head cover 200 can specifically be the cylinder head cover 200 of the engine.

[0041] The existing oil-gas separator 100 is generally an independent structure, and the oil-gas separator 100 requires an independent space for installation, which occupies a large space. In the present application, the oil-gas separator 100 is installed on the cylinder head cover 200, so that the oil-gas separator 100 does not need an independent space for installation, and occupies a small space. In addition, through the cooperation between the oil-gas separator 100 and the cylinder head cover 200, the structure of the oil-gas separation component can be simplified.

[0042] Reference Figure 4 and Figure 5 The guide plate 300 is disposed on the inner side of the cylinder head cover 200, and the guide plate 300 and the cylinder head cover 200 can enclose a connecting chamber 301 that is connected to the outlet 13 of the oil-gas separator 100, and one end of the connecting chamber 301 away from the outlet 13 forms a gas outlet 302 that is connected to the outside. The oil and separated gas separated in the oil-gas separator 100 flow into the connecting chamber 301 through the outlet 13, wherein the oil falls onto the guide plate 300, and the separated gas can flow in the connecting chamber 301 toward the gas outlet 302 of the connecting chamber 301.

[0043] In some specific embodiments, in order to facilitate the recycling of oil, the guide plate 300 is provided with a first control valve 303 and a first oil leakage hole 304 that penetrates the guide plate 300. The first oil leakage hole 304 is used to connect the connecting cavity 301 and the oil storage space in the engine. The first control valve 303 can be used to block the first oil leakage hole 304. Specifically, when the first control valve 303 is in a closed state, the first oil leakage hole 304 is blocked by the first control valve 303, and the oil is collected on the guide plate 300; when the first control valve 303 is in an open state, the first oil leakage hole 304 is opened, and the oil on the guide plate 300 can fall into the oil storage space of the engine through the first oil leakage hole 304 to achieve the recycling of the oil. Among them, the first control valve 303 can be a one-way valve. When the weight of the oil accumulated on the first control valve 303 meets the opening standard of the first control valve 303, the first control valve 303 opens under the gravity of the oil, and the oil is discharged through the first oil leakage hole 304; when the weight of the oil accumulated on the first control valve 303 cannot meet the opening standard of the first control valve 303, the first control valve 303 is in a closed state.

[0044] In some specific embodiments, the oil obtained after the mixed gas passes through the oil-gas separation unit 2 for the first oil-gas separation is discharged through the first oil leakage hole 304, and the separated gas obtained after the first oil-gas separation can be subjected to a second oil-gas separation during the flow process of the connecting chamber 301. Specifically, a plurality of staggered baffles 305 are arranged in the connecting chamber 301. When the separated gas obtained after the first oil-gas separation passes through the baffle 305, it will collide with the baffle 305 and change the flow direction to flow to the next baffle 305. The oil and gas in the separated gas are separated during the continuous collision between the separated gas and the baffle 305. The separated gas undergoes a second oil-gas separation under the action of the plurality of baffles 305. The oil obtained from the second oil-gas separation falls onto the guide plate 300, and the gas obtained from the second oil-gas separation is discharged through the gas outlet 302 of the connecting chamber 301. Among them, the baffle 305 can be set on the guide plate 300 or the cylinder head cover 200, the height of the baffle 305 can be the same as the height of the connecting chamber 301 and the baffle 305 begins to have a hole for gas to pass through, or the baffle 305 can be lower than the height of the connecting chamber 301.

[0045] In order to facilitate the recycling of the oil obtained by the second oil-gas separation, the guide plate 300 is provided with a second control valve 306 and a second oil leakage hole 307 that runs through the guide plate 300. The second oil leakage hole 307 is used to connect the connecting chamber 301 and the oil storage space in the engine. The second control valve 306 can be used to block the first oil leakage hole 304. Specifically, when the second control valve 306 is in a closed state, the second oil leakage hole 307 is blocked by the second control valve 306, and the oil obtained by the second oil-gas separation is gathered on the guide plate 300; when the second control valve 306 is in an open state, the second oil leakage hole 307 is opened, and the oil obtained by the second oil-gas separation on the guide plate 300 can fall into the oil storage space of the engine through the second oil leakage hole 307 to achieve the recycling of the oil. Among them, the second control valve 306 can be a one-way valve. When the weight of the oil accumulated on the second control valve 306 meets the opening standard of the second control valve 306, the second control valve 306 opens under the gravity of the oil, and the oil is discharged through the second oil leakage hole 307; when the weight of the oil accumulated on the second control valve 306 cannot meet the opening standard of the second control valve 306, the second control valve 306 is in a closed state.

[0046] The second oil leakage hole 307 is located downstream of the plurality of baffles 305 along the gas flow direction in the connecting chamber 301, that is, the second oil leakage hole 307 is located between the gas outlet end 302 and the baffle 305; the first oil leakage hole 304 is located upstream of the plurality of baffles 305 along the gas flow direction in the connecting chamber 301, that is, the first oil leakage hole 304 is located between the outlet 13 and the baffle 305. The oil separated by the oil-gas separation unit 2 is discharged through the first oil leakage hole 304, and the oil obtained by the second oil-gas separation through the plurality of baffles 305 is discharged through the second oil leakage hole 307.

[0047] The utility model also provides an automobile, comprising the above-mentioned oil-gas separation component, an engine main body and a turbocharger. The cylinder head cover 200 in the oil-gas separation component is a cylinder head cover 200 of the engine, and the cylinder head cover 200 is covered on the engine main body. The gas outlet end 302 of the connecting cavity 301 in the oil-gas separation component can be connected to the turbocharger, so that the gas discharged from the oil-gas separation component can flow to the turbocharger for use.

[0048] Although the embodiments of the utility model have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the utility model. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the utility model without departing from the principles and purpose of the utility model. All of these changes should fall within the scope of protection of the claims of the utility model.
