[0033] The present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limiting the present application.

[0034] Embodiment 1

[0035] Combination Figures 1 to 3 As shown, the first embodiment provides an oil-gas separation structure, which includes a shell 1 and an oil retaining structure 2 arranged in the shell 1, and the shell 1 has a first direction a and a second direction b that intersect each other.

[0036] It should be understood that the first direction a and the second direction b are not vector directions.

[0037] Furthermore, combined with Figures 1 to 3As shown, the oil baffle structure 2 includes a first oil baffle portion 21 and a second oil baffle portion 22 located in the shell 1; wherein, the first oil baffle portion 21 is spaced apart from one side of the shell 1 along the first direction a to form a first oil-gas separation channel 101, and the first oil baffle portion 21 is spaced apart from the other side of the shell 1 along the first direction a to form a second oil-gas separation channel 102, the first oil baffle portion 21 is connected to the shell 1, and the first oil baffle portion 21 is spaced apart from one side of the shell 1 along the second direction b to form a connecting port 103 connecting the first oil-gas separation channel 101 and the second oil-gas separation channel 102; the second oil baffle portion 22 is connected to the first oil baffle portion 21, the second oil baffle portion 22 is protruding relative to the first oil baffle portion 21 along the first direction a, and the second oil baffle portion 22 is located in the first oil-gas separation channel 101 and is spaced apart from the shell 1.

[0038] In this embodiment, the first oil baffle 21 and the second oil baffle 22 are both rectangular in shape. Of course, in other embodiments, the first oil baffle 21 and the second oil baffle 22 can be other shapes, as long as the first oil baffle 21 and the second oil baffle 22 can increase the heat dissipation area of ​​the high-temperature mixed oil and gas.

[0039] In this embodiment, the first oil baffle 21 is arranged inside the housing 1, dividing the inside of the housing 1 into a first oil-gas separation channel 101 and a second oil-gas separation channel 102, and connecting the first oil-gas separation channel 101 and the second oil-gas separation channel 102 through the connecting port 103, which can increase the flow distance of the high-temperature mixed oil and gas inside the housing 1, thereby increasing the cooling time of the high-temperature mixed oil and gas, which is conducive to the conversion of the high-temperature mixed oil and gas from gas to liquid after cooling. Further, a second oil baffle 22 is arranged on the first oil baffle 21, and the second oil baffle 22 can increase the heat dissipation area of ​​the high-temperature mixed oil and gas, and finally enable the high-temperature mixed oil and gas to be more effectively converted from gas to liquid.

[0040] In this embodiment, combined with Figures 1 to 3 As shown, the housing 1 includes a front housing c and a rear housing d, the front housing c and the rear housing d are connected, and only a first oil baffle 21 is provided in the rear housing d, and the first oil baffle 21 of the front housing c is arranged one-to-one with the first oil baffle 21 of the rear housing d.

[0041] In other embodiments, the front shell c and the rear shell d may also be configured to have the same structure, which may be specifically configured according to the thickness of the front shell c and the rear shell d.

[0042] Furthermore, combined with Figure 1 As shown, the oil-blocking structure 2 includes a plurality of second oil-blocking portions 22, and the second oil-blocking portions 22 are arranged at intervals from each other along the second direction b.

[0043] In this embodiment, the oil baffle structure 2 includes three second oil baffles 22, and two adjacent second oil baffles 22 are arranged at intervals from each other and are connected to the same side of the first oil baffle 21. The three second oil baffles 22 can increase the contact area for heat dissipation of the high-temperature mixed oil and gas, and more effectively convert the high-temperature mixed oil and gas from gas to liquid.

[0044] In other embodiments, the oil baffle structure 2 can be provided with a suitable number of second oil baffles 22 according to the size of the shell 1 to increase the contact area for heat dissipation of the high-temperature mixed oil and gas and better convert the high-temperature mixed oil and gas into liquid.

[0045] Combination Figure 1 and Figure 2 As shown, the shell 1 is provided with an oil and gas inlet 104 and an exhaust hole 105. The oil and gas inlet 104 is located in the shell 1 corresponding to the first oil and gas separation channel 101 along the second direction b, and is connected to the first oil and gas separation channel 101; the exhaust hole 105 is provided in the shell 1 corresponding to the second oil and gas separation channel 102 along the first direction a, and is connected to the second oil and gas separation channel 102.

[0046] In this embodiment, the oil and gas inlet 104 is connected to the first oil and gas separation channel 101, and the second oil baffle 22 is located in the first oil and gas separation channel 101. The second oil baffle 22 can not only increase the contact area for heat dissipation of the high-temperature mixed oil and gas, but also block part of the splashing oil from entering the shell 1.

[0047] Furthermore, combined with Figure 1 to Figure 2 As shown, the oil-gas separation structure further includes an exhaust plug 3, which is located in the exhaust hole 105. The gas in the shell 1 is discharged through the exhaust plug 3 to prevent oil leakage caused by increased air pressure in the shell 1.

[0048] In this embodiment, combined with Figure 1 As shown, the first oil baffle 21 is tiltedly arranged in the shell 1, and the vertical distance between the end of the first oil baffle 21 connected to the shell 1 and the oil and gas inlet 104 is greater than the vertical distance between the end of the first oil baffle 21 spaced apart from the shell 1 and the oil and gas inlet 104.

[0049] It should be understood that the first oil baffle 21 is tilted in the housing 1, which is conducive to the timely return of the cooled lubricating oil in the housing 1 by gravity without accumulation in the housing 1, thereby achieving the effect of reducing the loss of lubricating oil.

[0050] In addition, after the high-temperature mixed oil and gas is cooled and becomes liquid, it flows back from the oil and gas inlet 104 to the components that generate the high-temperature mixed oil and gas due to gravity. Therefore, the oil retaining structure 2 needs to be set above the oil and gas inlet 104 so that the liquid lubricating fluid can flow back to the components that generate the high-temperature mixed oil and gas through the oil and gas inlet 104.

[0051] Embodiment 2

[0052] Combination Figure 4 As shown, the second embodiment provides an oil-gas separation structure, which is substantially the same as the oil-gas separation structure of the first embodiment, except that the oil-gas separation structure of the second embodiment includes a plurality of oil retaining structures 2, thereby better converting the oil and gas in the high-temperature mixed oil and gas into liquid.

[0053] In this embodiment, combined with Figure 4 As shown, the oil-gas separation structure includes a plurality of oil retaining structures 2, and the plurality of oil retaining structures 2 are arranged at intervals along the first direction a. Arranging a plurality of oil retaining structures 2 in the housing 1 can not only further increase the flow path of the high-temperature mixed oil and gas inside the housing 1, but also increase the contact area for heat dissipation of the high-temperature mixed oil and gas, so as to better convert the high-temperature mixed oil and gas into liquid.

[0054] It should be understood that when the oil-gas separation structure includes multiple oil-blocking structures 2, the first oil-gas separation channel 101 of one oil-blocking structure 2 of two adjacent oil-blocking structures 2 overlaps with the second oil-gas separation channel 102 of the other oil-blocking structure 2, that is, the space between the two adjacent oil-blocking structures 2 along the first direction a can be the first oil-gas separation channel 101 of one oil-blocking structure 2, or the second oil-gas separation channel 102 of the other oil-blocking structure 2.

[0055] For example, the oil-gas separation structure includes two oil-blocking structures 2, and the two oil-blocking structures 2 are arranged at intervals from each other along the first direction a; wherein, both ends of the first oil-blocking portion 21 along the second direction b are arranged at intervals from the housing 1 to form a connecting port 103. Both ends of the first oil-blocking portion 21 are provided with a connecting port 103 connecting the first oil-gas separation channel 101 and the second oil-gas separation channel 102, so that the flow path of the high-temperature mixed gas in the housing 1 is more complicated, and the flow stroke of the high-temperature mixed oil and gas inside the housing 1 is increased, which is conducive to cooling the oil gas of the lubricating oil into oil liquid; at the same time, the second oil-blocking portion 22 can increase the contact area for heat dissipation of the high-temperature mixed oil and gas, which is also conducive to cooling the oil gas of the lubricating oil into oil liquid.

[0056] In other embodiments, both ends of the first oil baffle portion 21 along the second direction b may be spaced apart from the housing 1 . In this case, the first oil baffle portion 21 is connected to the housing 1 along the thickness direction of the housing 1 .

[0057] In addition, a suitable number of oil retaining structures 2 can be set according to the size of the shell 1 to increase the flow distance of the high-temperature mixed oil and gas inside the shell 1 and the contact area for heat dissipation of the high-temperature mixed oil and gas, so as to better convert the high-temperature mixed oil and gas into liquid.

[0058] Furthermore, combined with Figure 4 As shown, the positive projections of two adjacent oil-baffle structures 2 along the first direction a on the shell 1 at least partially overlap, which can further increase the flow distance of the high-temperature mixed oil and gas in the shell 1, and thus extend the cooling time of the high-temperature mixed oil and gas in the shell 1 to transform the lubricating oil in the mixed gas from gas to liquid.

[0059] Combination Figure 4 As shown, each second oil-blocking portion 22 in the plurality of oil-blocking structures 2 is protruded toward the same direction.

[0060] In this embodiment, the second oil baffles 22 are all protruding relative to the first oil baffle 21 in the direction of the oil and gas inlet 104, and are all connected to the side of the first oil baffle 21 close to the oil and gas inlet 104. The side of the first oil baffle 21 close to the oil and gas inlet 104 is connected to the second oil baffle 22, and the contact area of ​​the high-temperature mixed oil and gas heat dissipation is increased through the second oil baffle 22, so that the high-temperature mixed oil and gas is cooled into liquid; the side of the first oil baffle 21 away from the oil and gas inlet 104 is used to guide the liquid lubricating oil to flow back to the parts that generate the high-temperature mixed oil and gas through gravity, thereby reducing the loss of lubricating oil.

[0061] Embodiment 3

[0062] Combination Figures 5 to 10 As shown, the third embodiment provides an oil-gas separation structure, which is substantially the same as the oil-gas separation structure of the second embodiment, except that the positional relationship between two adjacent oil-blocking structures 2 of the third embodiment is different from the positional relationship between two adjacent oil-blocking structures 2 of the second embodiment, thereby enabling the high-temperature mixed oil and gas to be more effectively converted from gas to liquid.

[0063] In this embodiment, combined with Figures 5 to 7 As shown, the shell 1 includes a left shell portion 11 and a right shell portion 12 along the second direction b; wherein, in two adjacent oil-blocking structures 2: one oil-blocking structure 2 is connected to the left shell portion 11, and is spaced apart from the right shell portion 12 to form a connecting port 103; the other oil-blocking structure 2 is connected to the right shell portion 12, and is spaced apart from the left shell portion 11 to form a connecting port 103.

[0064] In this embodiment, combined with Figure 7As shown, one of the two adjacent oil-baffle structures 2 is connected to the left shell portion 11, and the other oil-baffle structure 2 is connected to the right shell portion 12, and an "S-shaped" channel is formed inside the shell 1, so that the flow path of the high-temperature mixed oil and gas after entering the shell 1 becomes complicated, and the flow range of the high-temperature mixed oil and gas is increased, thereby effectively increasing the cooling time of the high-temperature mixed oil and gas in the shell 1, so as to transform the high-temperature mixed oil and gas from gas to liquid.

[0065] It should be understood that when the high-temperature mixed oil and gas flows through the "S-shaped" channel, most of the oil and gas can be converted from gas to liquid. The liquid lubricating oil naturally flows back to the inner cavity of the component that produces the high-temperature mixed oil and gas due to gravity, which can effectively prevent the exhaust plug 3 from leaking oil.

[0066] Embodiment 4

[0067] The fourth embodiment provides a reducer, including a reducer body and the above-mentioned oil-gas separation structure, and the reducer body is connected to the reducer body.

[0068] In this embodiment, the reducer body is provided with an oil and gas outlet, which is connected to the oil and gas inlet 104, so that the high-temperature mixed oil and gas can be converted from gas to liquid after entering the oil and gas separation structure, preventing the lubricating oil from being discharged in the form of gas, causing oil leakage from the exhaust plug 3.

[0069] Regarding other structures of the reducer, please refer to the prior art and will not be described in detail here.

[0071] The fifth embodiment provides a vehicle, including a frame and the above-mentioned reducer, wherein the reducer is connected to the frame.
