Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a filter, an oil storage container, a lubrication system, and a vehicle. Background Technology

[0002] The electric drive system of new energy vehicles is highly dependent on the lubrication system. The lubrication system not only undertakes the functions of cooling and lubricating key moving parts, but also directly affects the working efficiency and service life of the motor and reducer. Under high speed and high power density operating conditions, the flow state, gas content and oil supply stability of the lubricating oil become one of the core factors determining the reliability of the electric drive system.

[0003] When lubricating oil is released from the return port of the lubrication system's oil reservoir, the released oil impacts the oil surface inside the reservoir, causing air bubbles to form. These bubbles, if sucked into the filter's suction port, can lead to oil pump cavitation and insufficient heat dissipation in the electric drive and reducer. In existing technology, multiple staggered baffles are installed inside the oil tank, creating a serpentine oil path. The return port and suction port correspond to different positions within this serpentine path, ensuring that air bubbles are eliminated by the time the returning lubricating oil reaches the suction port, thus reducing the number of air bubbles entering the suction port.

[0004] However, the existing technology for eliminating air bubbles is relatively complex, which is not conducive to the flow of lubricating oil in the oil tank, reduces the delivery efficiency of lubricating oil, and affects the lubrication effect. Utility Model Content

[0005] One of the objectives of this invention is to provide a filter, an oil storage container, a lubrication system, and a vehicle to address the existing technology's challenge of improving lubricating oil delivery efficiency while reducing air bubbles.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: The first aspect of this application provides a filter including a filter body and a flow guide; the filter body includes a first outer surface and a second outer surface disposed opposite to each other, the first outer surface is provided with an intake port, the flow guide is connected to the second outer surface, and the flow guide includes a flow guide structure protruding from the second outer surface away from the first outer surface.

[0007] Based on the aforementioned technical features, when lubricating oil is released from the oil return port of the oil tank, the lubricating oil falls onto the guide component due to gravity and the driving force of the pump. Since the lubricating oil falling from the return port first lands on the guide component, the impact force of the falling lubricating oil acts on the guide component, allowing it to be absorbed or dispersed. This reduces the risk of air bubbles being generated when the lubricating oil falls directly onto the surface of the lubricating oil in the oil tank due to the large impact force. Simultaneously, because the guide structure protrudes from the first outer surface of the second outer surface, the lubricating oil falling onto the guide component flows circumferentially along the guide structure, allowing it to more smoothly contact and merge with the lubricating oil stored in the oil tank, further preventing air bubble formation. Furthermore, after the lubricating oil flows back into the oil tank, the guide component does not obstruct the flow, ensuring smooth flow and effectively increasing the lubricating oil transfer efficiency.

[0008] In some embodiments, along a first direction, both ends of the flow guiding structure gradually extend towards the first outer surface at an angle, and the first direction is perpendicular to the arrangement direction of the first and second outer surfaces. The flow guiding structure includes a first flow guiding portion, a first blocking portion, and a second blocking portion. The first flow guiding portion is connected to the second outer surface. Along a second direction, the first blocking portion is connected to one side of the first flow guiding portion, and the second blocking portion is connected to the other side of the first flow guiding portion. Both the first blocking portion and the second blocking portion are located on the side of the first flow guiding portion away from the filter body. The first blocking portion, the second blocking portion, and the first flow guiding portion form a first flow guiding groove. The second direction is perpendicular to the first direction and is perpendicular to the arrangement direction of the first and second outer surfaces.

[0009] According to the above technical features, when the lubricating oil released from the return port comes into contact with the first guide section, the lubricating oil released from the return port will impact the first guide section, causing some of the lubricating oil dripping onto the first guide section to splash. The splashed lubricating oil will be blocked by the first and second blocking sections, and will flow back onto the first guide section along the surfaces of the first and second blocking sections, and then be guided by the first guide section to merge with the lubricating oil stored in the oil tank. This avoids the lubricating oil dripping onto the first guide section from splashing onto the surface of the lubricating oil stored in the oil tank, and avoids the splashed lubricating oil impacting the lubricating oil stored in the oil tank, thereby further reducing the probability of air bubbles forming in the lubricating oil.

[0010] In some embodiments, the surface of the first guide portion away from the second outer surface is an arc-shaped surface, and the arc-shaped surface protrudes along the direction from the first outer surface to the second outer surface.

[0011] Based on the above technical features, the arc-shaped surface of the first guide part away from the second outer surface can guide the lubricating oil more smoothly and allow the first guide part to guide the lubricating oil to a position closer to the surface of the lubricating oil stored in the oil tank for release. This effectively reduces the impact force when the lubricating oil guided by the first guide part comes into contact with the surface of the lubricating oil stored in the oil tank, and reduces the generation of air bubbles.

[0012] In some embodiments, the flow guide further includes a second flow guide portion and a third flow guide portion. The second flow guide portion is connected to one end of the first flow guide portion along a first direction, and the third flow guide portion is connected to the other end of the first flow guide portion along the first direction. The second flow guide portion and the third flow guide portion are both located on the side of the first flow guide portion close to the first outer surface, and are used to guide the liquid in the first flow guide groove along the direction from the second outer surface toward the first outer surface.

[0013] Based on the above technical features, the second and third guide sections are closer to the surface of the lubricating oil stored in the oil tank than the first guide section, which can further reduce the impact force of the lubricating oil released from the return port contacting the surface of the lubricating oil stored in the oil tank, and effectively reduce the number of bubbles generated.

[0014] In some embodiments, the second guide portion forms a second guide groove, the second guide groove is recessed toward the third guide portion along the first direction, and the second guide groove penetrates the second guide portion along the direction of the first outer surface and the second outer surface, and the second guide groove communicates with the first guide groove; and / or, the third guide portion forms a third guide groove, the third guide groove is recessed toward the second guide portion along the first direction, and the third guide groove penetrates the third guide portion along the direction of the first outer surface and the second outer surface, and the third guide groove communicates with the first guide groove.

[0015] Based on the above technical features, when the vehicle experiences vibration or impact, the second guide groove can prevent the lubricating oil from leaving the second guide section before it has flowed to the end of the second guide section away from the first guide section, and the third guide groove can prevent the lubricating oil from leaving the third guide section before it has flowed to the end of the third guide section away from the first guide section, thereby preventing the lubricating oil that has left the second guide section and the second guide section before it impacts the surface of the lubricating oil stored in the oil tank, and further preventing the generation of air bubbles.

[0016] In some embodiments, the filter body includes a housing and a filter element, with two opposite outer surfaces of the housing being a first outer surface and a second outer surface, and the filter element being connected inside the housing; along the arrangement direction of the first and second outer surfaces, the end of the second flow guide portion away from the first flow guide portion and the end of the third flow guide portion away from the first flow guide portion are both located on the side of the filter element away from the second outer surface.

[0017] Based on the above technical features, the ends of the second guide section away from the first guide section and the third guide section away from the first guide section are both located below the surface of the lubricating oil stored in the oil tank. This allows the second and third guide sections to directly guide the lubricating oil into the lubricating oil stored in the oil tank, further reducing the impact force of the lubricating oil released from the return port on the lubricating oil stored in the oil tank, thereby reducing the generation of air bubbles in the lubricating oil.

[0018] In some embodiments, the flow guiding structure further includes a third blocking portion located on the side of the first blocking portion away from the second blocking portion. The third blocking portion includes a first end and a second end arranged along a second direction. The first end is connected to the end of the first blocking portion away from the first flow guiding portion. Along the arrangement direction of the first outer surface and the second outer surface, the distance between the second end and the first outer surface is greater than the distance between the first end and the first outer surface. And / or, the flow guiding structure further includes a fourth blocking portion located on the side of the second blocking portion away from the first blocking portion. The fourth blocking portion includes a third end and a fourth end arranged along a second direction. The third end is connected to the end of the second blocking portion away from the first flow guiding portion. Along the arrangement direction of the first outer surface and the second outer surface, the distance between the fourth end and the first outer surface is greater than the distance between the third end and the first outer surface.

[0019] Based on the aforementioned technical features, the guide structure can still receive lubricating oil from the oil tank return port when the vehicle tilts, and guide the lubricating oil to the first guide section for further guidance. This effectively avoids the lubricating oil released from the return port directly contacting the lubricating oil stored in the oil tank and causing impact when the vehicle tilts, thus effectively reducing the generation of air bubbles.

[0020] The second aspect of this application provides an oil storage container, including an oil tank and a filter provided in the first aspect of this application. An oil return port is provided on the inner wall surface of the top of the oil tank. The filter is connected to the inside of the oil tank. Along the arrangement direction of the filter body and the guide member, the suction port and the oil return port of the filter body are spaced apart. The orthographic projection of the oil return port on a first plane is located within the orthographic projection of the guide member on the first plane. The first plane is perpendicular to the arrangement direction of the filter body and the guide member.

[0021] The third aspect of this application provides a lubrication system, including an oil storage container provided in the second aspect of this application.

[0022] The fourth aspect of this application provides a vehicle that includes the lubrication system provided in the third aspect of this application.

[0023] The beneficial effects of this utility model are: (1) When the lubricating oil flows out from the return port, it will first fall onto the guide. The guide can buffer the impact force of the falling lubricating oil and prevent it from directly hitting the oil surface in the tank and splashing air bubbles. At the same time, because the guide structure protrudes outward, it can guide the lubricating oil to flow smoothly along its circumference, so that it can flow into the lubricating oil in the tank more gently, effectively reducing the generation of air bubbles.

[0024] (2) The arc-shaped surface of the first guide section can guide the lubricating oil more smoothly and release it to a position close to the oil tank surface, reducing the impact force and thus reducing the generation of bubbles.

[0025] (3) When the lubricating oil falls from the return port to the first guide section, it may splash, but it will be blocked by the first and second blocking sections and flow back to the first guide section along its surface, and then smoothly flow into the lubricating oil in the oil tank. This avoids splashing oil droplets directly impacting the liquid surface and further reduces the generation of bubbles. Attached Figure Description

[0028] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation.

[0030] In the description of the embodiments in this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0031] In the description of the embodiments of this application, the term "multiple" refers to two or more, including two.

[0032] This application provides a vehicle that can be a freight vehicle or a passenger vehicle. This application does not limit the specific type of vehicle and allows for selection based on actual needs.

[0033] In some embodiments, the vehicle may include a lubrication system and a drive unit. The main function of the drive unit is to drive the vehicle to move. The main function of the lubrication system is to continuously supply an appropriate amount of clean lubricating oil to the drive unit of the vehicle, reduce wear between internal parts of the drive unit, reduce the internal operating temperature of the drive unit, prevent overheating of the drive unit, and carry away metal debris generated by friction between internal parts of the drive unit and other equipment during the circulation of the lubricating oil, thereby ensuring the efficient and stable operation of the drive unit.

[0034] For example, the drive unit may include components such as a reducer, a motor, and a drive shaft. This application does not limit the specific structure of the drive unit, and the drive unit can be selected according to actual conditions such as design and requirements. In some possible embodiments, the drive unit may include a distributed electric drive, which may include two motors spaced apart along the width direction of the vehicle.

[0035] In some embodiments, the lubrication system includes an oil reservoir, which is mainly used to store and supply lubricating oil, ensuring a sufficient and stable oil source for the lubrication system during the operation of equipment such as motors and reducers. Simultaneously, the oil reservoir also helps dissipate heat from the lubricating oil and settle impurities, thereby ensuring the normal circulation of the lubrication system and the reliable operation of the drive device. In some possible embodiments, the lubrication system may also include components such as lubricating oil pipes, a drive pump, and a valve body. The oil tank can be connected to the drive device through the lubricating oil pipes, and the drive unit is disposed on the lubricating oil pipes to provide power for the flow of lubricating oil in the pipes via the drive pump. This allows the lubrication system to transport the lubricating oil in the oil reservoir to the location requiring lubrication and cooling, and to return the lubricating oil that has participated in lubrication and cooling to the oil reservoir, thus achieving lubricating oil circulation. This application does not limit the specific structure of the lubrication system; it can be selected according to functional requirements and cost considerations.

[0036] like Figures 1 to 3 As shown, in some embodiments, the oil storage container includes an oil tank 3 and a filter. The inner wall of the top of the oil tank 3 is provided with an oil return port 301, which can communicate with the interior of the drive unit. The main function of the oil tank 3 is to store and supply lubricating oil. In some possible embodiments, the oil tank 3 may also include an oil outlet. The oil outlet of the oil tank 3 can release lubricating oil into the lubricating oil pipeline of the lubricating oil system, and through the drive pump, the lubricating oil flows through the vehicle's drive unit, and then flows back into the interior of the oil tank 3 from the oil return port 301, thus completing the circulation of lubricating oil within the lubrication system.

[0037] In some possible embodiments, the oil tank 3 can be located at the bottom of the drive unit, allowing the lubricating oil of the drive unit to flow back into the oil tank 3 naturally by gravity, facilitating the centralized collection and recycling of the lubricating oil. This also helps to lower the vehicle's center of gravity and improve overall stability. In some possible embodiments, when the vehicle uses a distributed dual-electric drive system, to ensure the consistency of the lubricating oil inside the two motors, the oil tank 3 needs to be located in the middle of the two electric drives, and the oil return port 301 is also located in the middle of the two motors, that is, in the middle of the inner top wall of the oil tank 3.

[0038] When lubricating oil flows through equipment such as reducers and motors, it carries impurities from inside the reducers and motors back to the oil tank 3. These impurities settle at the bottom of the oil tank 3. The oil return port 301 is located on the inner wall of the top of the oil tank 3, away from the settled impurities at the bottom. This prevents the lubricating oil released from the return port 301 from directly impacting the settled impurities and metal shavings at the bottom of the oil tank 3, preventing these impurities from being stirred up and mixed into the lubricating oil again. This reduces secondary contamination of the lubrication system and ensures the cleanliness and lubrication effect of the lubricating oil.

[0039] The filter is located inside the oil tank 3. Its main function is to prevent impurities inside the oil tank 3 from flowing back into the motor and reducer with the lubricating oil. In some possible embodiments, the filter's outlet can be connected to the oil outlet of the oil tank 3, so that the filtered lubricating oil can be transferred to the drive unit through the oil outlet of the oil tank 3. For example, the filter can be bolted to the inner wall of the oil tank 3, or it can be welded to the inner wall of the oil tank 3. This application does not limit the specific connection method between the filter and the oil tank 3; the choice can be made based on cost and process considerations.

[0040] The filter may include a filter body 1, which may be provided with an intake port 102. The intake port 102 is used to draw lubricating oil from inside the oil tank into the filter body 1 for filtration. The intake port 102 of the filter body 1 is located in the middle of the oil tank 3 because when the vehicle tilts, the lubricating oil in the oil tank 3 will also tilt due to gravity, and the lubricating oil will converge on the side with a lower tilt, causing the liquid level on that side to rise. On the side with a higher tilt, the lubricating oil will decrease, causing the liquid level on that side to drop. However, the change in the lubricating oil level in the middle of the oil tank 3 is minimal. By placing the intake port 102 of the filter body 1 in the middle of the oil tank 3, it is ensured that the filter body 1 can still draw lubricating oil when the vehicle tilts. Since the return port 301 of the oil tank 3 is located in the middle of the oil tank, and the intake port 102 is located in the middle of the oil tank 3, the intake port 102 and the return port 301 of the filter body are spaced apart along the arrangement direction of the filter body 1 and the guide member 2.

[0041] In some other possible embodiments, the oil return port 301 of the oil tank 3 may also be located on the inner wall surface of the top of the oil tank 3 near the edge. Meanwhile, along the arrangement direction of the filter body 1 and the guide member 2, the filter body's suction port 102 and the oil return port 301 are spaced apart. This application does not limit the specific locations of the oil return port 301 of the oil tank 3 and the filter suction port 102; they can be selected according to actual conditions such as design and process.

[0042] like Figure 1 , Figures 3 to 5 As shown, in some embodiments, the filter includes a filter body 1 and a flow guide 2; the filter body 1 includes a first outer surface 1011 and a second outer surface 1012 disposed opposite to each other, and the first outer surface 1011 is provided with an intake port 102; the main function of the filter body 1 is to filter the lubricating oil inside the oil tank 3. In some possible embodiments, the filter can be used to filter lubricating oil.

[0043] In some possible embodiments, the suction port 102 of the filter body 1 can be positioned below the lubricating oil level in the oil tank 3, and the suction port 102 of the filter body 1 can be positioned facing the bottom of the oil tank 3. It can be understood that the first outer surface 1011 of the filter body 1 is positioned on the side of the second outer surface 1012 away from the oil return port 301 of the oil tank 3. This arrangement ensures that the suction port 102 of the filter body 1 can stably draw in the lubricating oil in the oil tank 3.

[0044] The guide member 2 is connected to the second outer surface 1012, and the guide member 2 includes a guide structure that protrudes from the second outer surface 1012 away from the first outer surface 1011. This can be understood as the guide structure protruding from the second surface towards the oil return port 301, and the second outer surface 1012 of the filter body 1 facing the oil return port 301. When lubricating oil is released from the oil return port 301 of the oil tank 3, the lubricating oil falls onto the guide member 2 due to gravity and the driving force of the pump. Since the lubricating oil falling from the oil return port 301 first falls onto the guide member 2, the impact force of the falling lubricating oil can act on the guide member 2, so that the impact force is absorbed or dispersed by the guide member 2, reducing the risk of the lubricating oil surface being splashed and generating bubbles when the lubricating oil falls directly onto the lubricating oil surface in the oil tank due to the large impact force. Meanwhile, since the guide structure protrudes from the second outer surface away from the first outer surface, the lubricating oil falling onto the guide member 2 will flow along the circumference of the guide structure under its guidance, so that the lubricating oil can more smoothly contact and merge with the lubricant stored in the oil tank 3, further avoiding the generation of air bubbles. Furthermore, after the lubricating oil flows back into the oil tank 3, the guide member 2 will not obstruct the lubricating oil, and the lubricating oil flows more smoothly in the oil tank, thereby effectively increasing the transmission efficiency of the lubricating oil.

[0045] like Figures 1 to 5 As shown, in some embodiments, the orthographic projection of the oil return port 301 on the first plane is located within the orthographic projection of the guide member 2 on the first plane, and the first plane is perpendicular to the arrangement direction of the filter body 1 and the guide member 2. It can be understood that, viewed along the direction from the guide member 2 to the oil return port 301, the guide member 2 completely blocks the oil return port 301. This arrangement allows the lubricating oil released from the oil return port 301 to flow onto the guide member 2, preventing the lubricating oil released from the oil return port 301 from impacting the lubricating oil surface inside the oil tank 3, thereby preventing the formation of air bubbles in the lubricating oil inside the oil tank 3. For example, the first plane can be a plane on the oil tank 3, or it can be an imaginary plane; this application does not limit the specific setting of the first plane.

[0046] like Figures 1 to 5As shown, in some embodiments, along the first direction A, both ends of the flow guiding structure gradually extend inclined towards the first outer surface 1011, and the first direction A is perpendicular to the arrangement direction of the first outer surface 1011 and the second outer surface 1012. In some possible embodiments, the first direction A can also be understood as the height direction of the oil tank 3, and the first direction A can also be connected as the arrangement direction of the guide member and the filter body 1. The flow guiding structure can guide the lubricating oil to both sides of the oil suction port along the first direction A, while making the lubricating oil guided by the flow guiding structure more smoothly merge with the lubricating oil stored in the oil tank 3.

[0047] With this configuration, the flow guiding structure can guide the lubricating oil released from the return port 301 to both sides of the flow guiding structure from the center of the flow guiding structure. Since the first outer surface 1011 is located below the surface of the lubricating oil stored in the oil tank 3, the two ends of the flow guiding structure gradually extend towards the first outer surface 1011 along the first direction A, which enables the flow guiding structure to guide the lubricating oil to the lubricating oil stored in the oil tank 3 more smoothly, effectively reducing the impact generated when the lubricating oil converges and reducing the generation of air bubbles.

[0048] like Figures 1 to 5 As shown, in some embodiments, the flow guiding structure includes a first flow guiding part 201, a first blocking part 202, and a second blocking part 203. The first flow guiding part 201 is connected to the second outer surface 1012 along the second direction B. The first blocking part 202 is connected to one side of the first flow guiding part 201, and the second blocking part 203 is connected to the other side of the first flow guiding part 201. The first blocking part 202 and the second blocking part 203 are both located on the side of the first flow guiding part 201 away from the filter body 1. The first blocking part 202, the second blocking part 203, and the first flow guiding part 201 form a first flow guiding groove C. In some possible embodiments, the opening of the first flow guiding groove C can face the return port. When the return port releases lubricating oil, the lubricating oil will fall onto the first flow guiding part 201. The first flow guiding part 201 can guide the flow of lubricating oil and eventually merge with the lubricating oil stored in the oil tank 3. The second direction B is perpendicular to the first direction A, and the second direction B is perpendicular to the arrangement direction of the first outer surface 1011 and the second outer surface 1012. In some possible embodiments, the first direction A may be the length direction of the vehicle, the second direction B may be the width direction of the vehicle, and the arrangement direction of the first outer surface 1011 and the second outer surface 1012 may be the height direction of the vehicle.

[0049] When the lubricating oil released from the return port comes into contact with the first guide section 201, the impact between the lubricating oil and the first guide section 201 causes some of the lubricating oil dripping onto the first guide section 201 to splash. The splashed lubricating oil is blocked by the first blocking section 202 and the second blocking section 203, and flows back onto the first guide section 201 along the surfaces of the first blocking section 202 and the second blocking section 203, where it is guided to merge with the lubricating oil stored in the oil tank 3. This prevents the lubricating oil dripping onto the first guide section 201 from splashing onto the surface of the lubricating oil stored in the oil tank 3, and avoids the splashed lubricating oil impacting the lubricating oil stored in the oil tank 3, thereby further reducing the probability of air bubbles forming in the lubricating oil.

[0050] In some possible embodiments, the first flow guide 201, the first blocking part 202 and the second blocking part 203 may be integrally formed, and the first blocking part 202 and the second blocking part 203 may also be connected to the first flow guide 201 by welding. This application does not limit the specific connection method of the first flow guide 201, the first blocking part 202 and the second blocking part 203.

[0051] In some possible embodiments, the first blocking part 202 and the second blocking part 203 can both be baffles extending along the first direction A. And along the arrangement direction of the first outer surface 1011 and the second outer surface 1012, the first blocking part 202 and the second blocking part 203 can both have a certain height, so that both the first blocking part 202 and the second blocking part 203 can block splashed lubricating oil. In other possible embodiments, the first blocking part 202 and the second blocking part 203 can also be blocking blocks. This application does not limit the specific structure of the first blocking part 202 and the second blocking part 203; they can be selected according to actual conditions such as cost and process.

[0052] like Figures 1 to 5 As shown, in some embodiments, the surface of the first guide portion 201 away from the second outer surface 1012 is an arc-shaped surface, which protrudes along the direction from the first outer surface 1011 to the second outer surface 1012. The arc-shaped surface of the first guide portion 201 away from the second outer surface 1012 allows for a more stable flow of lubricating oil and enables the first guide portion 201 to guide the lubricating oil to a position closer to the surface of the lubricating oil stored in the oil tank 3 for release. This effectively reduces the impact force when the lubricating oil guided by the first guide portion 201 comes into contact with the surface of the lubricating oil stored in the oil tank 3, and reduces the generation of air bubbles.

[0053] In some other possible embodiments, the surface of the first guide portion 201 away from the second outer surface 1012 may also be a stepped surface, through which the lubricating oil released from the oil return port 301 is guided to the lubricating oil level stored in the oil tank 3. This application does not limit the specific structure of the first guide portion 201, and can be selected according to actual conditions such as cost and design.

[0054] like Figures 1 to 5 As shown, in some embodiments, the flow guide 2 further includes a second flow guide 204 and a third flow guide 205; the second flow guide 204 is connected to one end of the first flow guide 201 along the first direction A, and the third flow guide 205 is connected to the other end of the first flow guide 201 along the first direction A; both the second flow guide 204 and the third flow guide 205 are located on the side of the first flow guide 201 closer to the first outer surface 1011, thus, the second flow guide 204 and the third flow guide 205 are closer to the surface of the lubricating oil stored in the oil tank 3 than the first flow guide 201. The second flow guide 204 and the third flow guide 205 are used to guide the liquid in the first flow guide groove C along the direction from the second outer surface 1012 toward the first outer surface 1011.

[0055] The first guide section 201 can guide the lubricating oil released from the return port 301 to the second guide section 204 and the third guide section 205. The lubricating oil guided by the first guide section to the second guide section 204 can be the first lubricating oil, and the lubricating oil guided by the first guide section to the third guide section 205 can be the second lubricating oil. The second guide section 204 can guide the first lubricating oil to a position closer to the lubricating oil level stored in the oil tank 3 for release. Similarly, the third guide section 205 can guide the second lubricating oil to a position closer to the lubricating oil level stored in the oil tank 3 for release. This can further reduce the impact force of the lubricating oil released from the return port 301 contacting the lubricating oil level stored in the oil tank 3, and effectively reduce the number of air bubbles generated.

[0056] In some possible embodiments, the first guide portion 201, the second guide portion 204, and the third guide portion 205 may be integrally formed, and the second guide portion 204 and the third guide portion 205 may also be welded to the first guide portion 201. This application does not limit the specific connection method of the first guide portion 201, the second guide portion 204, and the third guide portion 205, and the selection can be made according to the actual situation such as process and cost.

[0057] In some embodiments, the second guide portion 204 forms a second guide groove D, which is recessed toward the third guide portion 205 along the first direction A, and extends through the second guide portion 204 along the direction of the first outer surface 1011 and the second outer surface 1012. The second guide groove D communicates with the first guide groove C. In some possible embodiments, the first guide portion 201, the first blocking portion 202, and the second blocking portion 203 are all connected to the second guide portion 204 so that the first guide groove C communicates with the second guide groove D, allowing the lubricating oil in the first guide groove C to enter the second guide groove D and be released from the side of the second guide groove D away from the first guide portion 201.

[0058] like Figures 1 to 5 As shown, in some embodiments, the third guide portion 205 forms a third guide groove E, which is recessed towards the second guide portion 204 along the first direction A, and extends through the third guide portion 205 along the direction of the first outer surface 1011 and the second outer surface 1012. The third guide groove E communicates with the first guide groove C. In some possible embodiments, the first guide portion 201, the first blocking portion 202, and the second blocking portion 203 are all connected to the third guide portion 205, so that the first guide groove C communicates with the third guide groove E, allowing the lubricating oil in the first guide groove C to enter the third guide groove E and be released from the side of the third guide groove E away from the first guide portion 201.

[0059] The lubricating oil guided by the first guide section 201 to the second guide section 204 and the third guide section 205 flows along the inner wall of the second guide groove D and the inner wall of the third guide groove E to the lubricating oil surface stored in the oil tank 3. When the vehicle vibrates or is impacted, the second guide groove D can prevent the lubricating oil from leaving the second guide section 204 before it flows to the end of the second guide section 204 away from the first guide section 201. Similarly, the third guide groove can prevent the lubricating oil from leaving the third guide section 205 before it flows to the end of the third guide section 205 away from the first guide section 201. This prevents the lubricating oil that leaves the second guide section 204 prematurely from impacting the lubricating oil surface stored in the oil tank 3, further preventing the generation of air bubbles.

[0060] like Figures 1 to 5As shown, in some embodiments, the filter body 1 includes a housing 101 and a filter element 103. The two opposite outer surfaces of the housing 101 are a first outer surface 1011 and a second outer surface 1012, respectively. The main purpose of the filter element 103 is to filter lubricating oil. For example, the filter element 103 can be a filter screen, allowing lubricating oil to pass through while impurities in the lubricating oil cannot, thus achieving filtration. The filter screen can be inclined and disposed inside the housing 101. The filter element 103 can also be a magnetic component, capable of attracting metal debris in the lubricating oil to achieve filtration. This application does not limit the specific structure of the filter element 103; it can be selected based on filtration requirements and cost considerations.

[0061] In some possible embodiments, when the filter body 1 is disposed inside the oil tank 3, the filter element 103 is located below the surface of the lubricating oil stored in the oil tank 3, so that the filter element 103 can fully filter the lubricating oil. The filter element 103 is connected to the inside of the housing 101. For example, the filter element 103 can be connected to the housing 101 by bolts, or the filter element 103 can be connected to the housing 101 by a slot. This application does not limit the specific connection method between the filter element 103 and the housing 101, and the method can be selected according to the actual situation such as process and cost.

[0062] Along the arrangement direction of the first outer surface 1011 and the second outer surface 1012, the end of the second guide portion 204 away from the first guide portion 201 and the end of the third guide portion 205 away from the first guide portion 201 are both located on the side of the filter element 103 away from the second outer surface 1012. This arrangement ensures that the ends of the second guide portion 204 and the third guide portion 205 away from the first guide portion 201 are both below the surface of the lubricating oil stored in the oil tank 3. This allows the second guide portion 204 and the third guide portion 205 to directly guide the lubricating oil into the lubricating oil stored in the oil tank 3, further reducing the impact force of the lubricating oil released from the return port 301 on the lubricating oil stored in the oil tank 3, thereby reducing the generation of air bubbles in the lubricating oil.

[0063] like Figures 1 to 5As shown, in some embodiments, the flow guiding structure further includes a third blocking portion 206, which is located on the side of the first blocking portion 202 away from the second blocking portion 203. The third blocking portion 206 includes a first end and a second end arranged along the second direction B. The first end is connected to the end of the first blocking portion 202 away from the first flow guiding portion 201. Along the arrangement direction of the first outer surface 1011 and the second outer surface 1012, the distance between the second end and the first outer surface 1011 is greater than the distance between the first end and the first outer surface 1011. It can be understood that when the flow guiding member 2 is viewed directly along the first direction A, the third blocking portion 206 is inclined relative to the first blocking portion 202.

[0064] like Figures 1 to 5 As shown, in some embodiments, the flow guiding structure further includes a fourth blocking portion 207. The fourth blocking portion 207 is located on the side of the second blocking portion 203 away from the first blocking portion 202. The fourth blocking portion 207 includes a third end and a fourth end arranged along the second direction B. The third end is connected to the end of the second blocking portion 203 away from the first flow guiding portion 201. Along the arrangement direction of the first outer surface 1011 and the second outer surface 1012, the distance between the fourth end and the first outer surface 1011 is greater than the distance between the third end and the first outer surface 1011. It can be understood that when the flow guiding member 2 is viewed directly along the first direction A, the fourth blocking portion 207 is inclined relative to the second blocking portion 203. It can also be understood that along the direction from the first outer surface 1011 to the second outer surface, the distance between the third blocking portion 206 and the fourth blocking portion 207 gradually increases.

[0065] When the vehicle is level, the first outer surface 1011 and the second outer surface 1012 can be arranged vertically. The first guide channel C is located below the oil return port 301. When the oil return port 301 releases lubricating oil, the lubricating oil can directly enter the first guide channel C. However, when the vehicle tilts to one side along the width direction, the guide member 2 also tilts. But the lubricating oil released from the oil return port 301 hardly tilts due to gravity, and the lubricating oil released from the oil return port 301 still falls vertically. At this time, the third blocking part 206 can block the lubricating oil released from the oil return port 301 and guide the lubricating oil to the first guide member 2. Similarly, when the vehicle tilts to the other side along the width direction, the fourth blocking part 207 can block the lubricating oil released from the oil return port 301 and guide the lubricating oil to the first guide member 2.

[0066] This design allows the flow guide structure to still receive lubricating oil from the oil return port 301 of the oil tank 3 when the vehicle tilts, and guides the lubricating oil to the first flow guide section 201 for further guidance. This effectively prevents the lubricating oil released from the oil return port 301 from directly contacting the lubricating oil stored in the oil tank 3 and causing impact when the vehicle tilts, thus effectively reducing the generation of air bubbles.

[0067] In some possible embodiments, the first blocking part 202 and the third blocking part 206, as well as the second blocking part 203 and the fourth blocking part 207, can all be integrally formed. The first blocking part 202 and the third blocking part 206, as well as the second blocking part 203 and the fourth blocking part 207, can also be connected by welding. This application does not limit the specific connection method of the first blocking part 202 and the third blocking part 206, or the specific connection method of the second blocking part 203 and the fourth blocking part 207. The connection can be selected according to actual conditions such as cost and process.

[0068] The above embodiments are merely preferred embodiments provided to fully illustrate the present utility model, and the protection scope of the present utility model is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present utility model are all within the protection scope of the present utility model.
