[0035] Reference below Figure 1-Figure 6 A bypass valve 100 according to an embodiment of the present invention is described.

[0036] like Figure 1 As shown, a bypass valve 100 according to an embodiment of the present invention includes a bypass housing 10 , a movable member 20 and an elastic member 30 .

[0037] The bypass housing 10 has an oil passage 11, which is used to connect the filter element 200. The movable member 20 is movably connected to the bypass housing 10, and the movable member 20 is provided with a pressure-bearing surface 21. The movable member 20 has a blocking position and an escape position. When the movable member 20 is in the blocking position, the pressure-bearing surface 21 blocks the oil passage 11. When the movable member 20 is in the escape position, the pressure-bearing surface 21 is spaced from the oil passage 11. One end of the elastic member 30 is connected to the bypass housing 10, and the other end is connected to the movable member 20, so that the movable member 20 has a tendency to move to the blocking position.

[0038] Among them, the oil passage 11 is arranged in the bypass housing 10, and the oil passage 11 is used to connect the oil outlet passage 201 on the filter element 200. The clean oil filtered by the filter element 200 flows to the oil outlet passage 201, and the oil flows through the oil passage 11. The bypass valve 100 can be installed in the vehicle engine lubrication system, and the oil is supplied to the vehicle engine. The movable part 20 can move, and the elastic part 30 is located between the bypass housing 10 and the movable part 20. For example, the elastic part 30 is a spring, and the elastic part 30 applies elastic force to the movable part 20, so that the movable part 20 has inertia.

[0039] The movable part 20 switches between two positions. When the movable part 20 is in the blocking position, the pressure-bearing surface 21 blocks the oil channel 11, so that the oil is retained in the oil channel 11, wherein the side of the movable part 20 may abut against the inner wall of the oil channel 11, and the pressure-bearing surface 21 blocks the oil channel 11, or the side of the movable part 20 where the pressure-bearing surface 21 is located abuts against the outer wall of the bypass shell 10, and the pressure-bearing surface 21 blocks the oil channel 11; when the movable part 20 is in the avoidance position, the pressure-bearing surface 21 is spaced apart from the oil channel 11, and the oil flows from the oil channel 11 to the oil outlet channel 201 on the filter element 200, thereby playing the role of the bypass valve 100.

[0040] It can be understood that the elastic member 30 exerts an elastic force on the movable member 20, so that the movable member 20 has a tendency to move to the blocking position. The movable member 20 has the inertia of stopping against the bypass housing 10. The movable member 20 is in the blocking position, and the pressure-bearing surface 21 blocks the oil channel 11. The pressure-bearing surface 21 bears the pressure of the oil. When the oil pressure is large, it will overcome the elastic force of the elastic member 30, thereby pushing the movable member 20 to move to the avoidance position. When the movable member 20 moves to the avoidance position, the pressure-bearing surface 21 is separated from the oil channel 11, the oil channel 11 is not blocked, and the oil in the oil channel 11 flows to the oil outlet channel 201 on the filter element 200.

[0041] In the related art, a filter element is used in a vehicle lubrication system to filter impurities in the engine oil to keep the engine oil clean. The filter element is connected to a bypass valve. When the filter element is clogged, the bypass valve is opened to allow the engine oil to directly enter the engine. However, in the related art, a first spherical surface is provided on the movable valve core of the bypass valve, and a second spherical surface is provided on the filter element. The first spherical surface and the second spherical surface are sealed together. The first spherical surface and the second spherical surface fit too closely, and the bypass valve can only be opened when the engine oil pressure is relatively high. The bypass valve is not sensitive.

[0042] In the embodiment of the utility model, a movable part 20 having a pressure-bearing surface 21 is provided, and the pressure of the engine oil acts on the entire pressure-bearing surface 21. Even if the engine oil pressure changes slightly, the part of the movable part 20 in contact with the engine oil is the pressure-bearing surface 21, and the movable part 20 will also be subject to a larger pressure change, thereby improving the sensitivity of the bypass valve 100.

[0043] Specifically, when the movable part 20 is in the blocking position, the surface of the movable part 20 contacting the oil is the pressure-bearing surface 21, and the oil is located in the oil channel 11, and the oil channel 11 is the space in the bypass shell 10, that is, the surface of the movable part 20 contacting the oil channel 11 is the pressure-bearing surface 21.

[0044] According to the bypass valve 100 of the embodiment of the utility model, a movable part 20 with a pressure-bearing surface 21 is provided, and the surface of the movable part 20 in contact with the oil space is the pressure-bearing surface 21. The pressure of the oil acts on the entire pressure-bearing surface 21. Even if the oil pressure changes slightly, the part of the movable part 20 in contact with the oil is the pressure-bearing surface 21, and the movable part 20 will also be subject to a larger pressure change, thereby improving the sensitivity of the bypass valve 100.

[0045] In some embodiments, a limiting portion is provided on the bypass housing 10, and the movable member 20 is connected to the limiting portion. The movable member 20 moves under the limitation of the limiting portion, so that the movable member 20 is more stable. For example, the limiting portion is a limiting column, which is inserted into a through hole on the movable member 20, and the limiting column guides the movement of the movable member 20, wherein the limiting portion can be provided on the outer wall of the bypass housing 10, or on the inner wall of the bypass housing 10.

[0046] like Figures 1 to 3 As shown, in some embodiments, the movable member 20 includes: a movable body 22 and a blocking portion 23 .

[0047] The movable body 22 is at least partially disposed in the oil passage 11 and is movably disposed. The blocking portion 23 is disposed at one end of the movable body 22 and is provided with a sealing surface 231 that seals with the bypass housing 10 . The side of the blocking portion 23 facing the oil passage 11 is configured as a pressure-bearing surface 21 .

[0048] Among them, the movable body 22 is movably arranged in the oil channel 11, and the sealing part 23 on the movable body 22 moves together with the movable body 22. The pressure-bearing surface 21 is arranged on the sealing part 23, and the sealing part 23 extends in the direction away from the movable body 22. The pressure-bearing surface 21 faces the oil channel 11, and the sealing surface 231 is sealed with the bypass shell 10 to seal the oil channel 11.

[0049] In the above scheme, by setting the movable body 22 and the sealing part 23, the sealing part 23 extends in the direction away from the movable body 22, and the side of the sealing part 23 facing the oil channel 11 is constructed as a pressure-bearing surface 21. The structure of the sealing part 23 facilitates the pressure-bearing surface 21 to contact the oil, and the overall structure is simple.

[0050] For example, the side surface of the sealing portion 23 facing the bypass shell 10 is constructed as a sealing surface 231, and the sealing surface 231 abuts against the bypass shell 10. It can be understood that the side area of ​​the sealing portion 23 facing the bypass shell 10 is larger, and the upper part of the side surface abuts against the bypass shell 10 to achieve sealing, and the other part of the side surface is the pressure-bearing surface 21, and the pressure-bearing surface 21 contacts the engine oil; or, when the movable part 20 is in the blocking position, the sealing portion 23 is located in the engine oil channel 11, and the surrounding wall of the sealing portion 23 is constructed as a sealing surface 231, and the sealing surface 231 abuts against the inner wall of the engine oil channel 11 to achieve sealing, and the side surface of the sealing portion 23 facing the engine oil channel 11 is the pressure-bearing surface 21.

[0051] like Figure 1 As shown, in some embodiments, the blocking portion 23 is at least partially disposed outside the oil passage 11 , and a sealing surface 231 is disposed on the portion of the blocking portion 23 outside the oil passage 11 . When the movable member 20 is in the blocking position, the sealing surface 231 stops against the bypass housing 10 .

[0052] It can be understood that the blocking portion 23 is at least partially disposed outside the oil passage 11 , that is, the blocking portion 23 may be entirely outside the oil passage 11 , or may be partially inside the oil passage 11 and partially outside the oil passage 11 .

[0053] Among them, the sealing part 23 is relatively large, and part of the structure of the sealing part 23 is located outside the oil channel 11. The sealing component is arranged on the part of the sealing part 23 located outside the oil channel 11, and the sealing surface 231 stops on the bypass shell 10, and the end face between the sealing part 23 and the bypass shell 10 is hard sealed.

[0054] In the above embodiment, a sealing surface 231 is provided on the portion of the sealing portion 23 outside the oil passage 11, and the sealing surface 231 abuts against the bypass housing 10 to achieve an end face hard seal between the sealing portion 23 and the bypass housing 10. Compared with the solution of using a rubber ring to seal the bypass valve in the related art, the embodiment of the utility model avoids the problem that the oil passes directly from the bypass valve 100 instead of the filter element due to the falling off or damage of the rubber ring, thereby improving the reliability of the bypass valve 100.

[0055] For example, the sealing portion 23 is constructed in a plate shape, and the plate-shaped sealing portion 23 is located outside the oil channel 11. The upper part of the side of the sealing portion 23 facing the bypass shell 10 is a sealing surface 231, and the other part is a pressure-bearing surface 21; or, the sealing portion 23 is constructed as a multi-layer structure, and the size of the second layer structure is larger than the first layer structure. When the movable part 20 is in the sealing position, the first layer structure is located in the oil channel 11, and the surface of the first layer structure facing the oil channel 11 is the pressure-bearing surface 21, and the second layer structure is located outside the oil channel 11, and the surface of the second layer structure facing the bypass shell 10 is the sealing surface 231.

[0056] like Figure 4 As shown, in some embodiments, a support member 12 is further provided in the oil passage 11 , a limiting hole 121 is provided on the support member 12 , and the movable body 22 is movably disposed in the limiting hole 121 .

[0057] The support member 12 is located in the oil passage 11 , the limiting hole 121 is opened on the support member 12 , the movable body 22 is passed through the limiting hole 121 , and the limiting hole 121 exerts a limiting effect.

[0058] In the above embodiment, by providing a support member 12 with a limiting hole 121, the movable body 22 is inserted into the limiting hole 121, and the limiting hole 121 abuts against the peripheral wall of the movable body 22, so that the movable body 22 moves more stably and the reliability is improved.

[0059] Specifically, the inner wall of the limiting hole 121 contacts the peripheral wall surface of the movable body 22 , thereby increasing the contact area and further improving the stability.

[0060] like Figure 4 As shown, in some embodiments, the support member 12 includes: a support body 122 and an extension portion 123 .

[0061] The limiting hole 121 is provided on the supporting body 122. The extension part 123 is provided on the side of the supporting body 122, and the extension part 123 extends toward the inner wall of the oil passage 11 and connects to the inner wall of the oil passage 11; wherein, there are multiple extension parts 123, and an avoidance opening 1231 is defined between two adjacent extension parts 123.

[0062] The extension part 123 is arranged between the support body 122 and the inner wall of the oil passage 11, and the two ends of the extension part 123 are respectively connected to the support body 122 and the inner wall of the oil passage 11. A plurality of extension parts 123 are arranged at intervals, and the avoidance opening 1231 is arranged between two adjacent extension parts 123. The structure of the avoidance opening 1231 allows the oil to flow freely.

[0063] In the above embodiment, the support body 122 cooperates with the extension part 123, and the movable body 22 is movably arranged in the limiting hole 121 on the support body 122. The support body 122 supports the movable body 22, and an avoidance port 1231 is arranged on the circumference of the support body 122 to avoid the engine oil so that the engine oil can flow freely, and the overall structure is stable and reliable.

[0064] In some specific embodiments, the movable body 22 is located on the axis of the oil passage 11 , so that the bypass valve 100 is more stable as a whole.

[0065] like Figure 4 As shown, in some specific embodiments, the support member 12 is integrally formed with the bypass housing 10, thereby reducing the number of parts and reducing the assembly process.

[0066] like Figure 1 As shown, in some embodiments, the elastic member 30 is disposed in a space defined by the inner wall of the oil passage 11 , the extension portion 123 and the movable body 22 , and one end of the elastic member 30 is connected to the extension portion 123 , and the other end is connected to the movable body 22 .

[0067] The inner wall of the oil passage 11 , the extension portion 123 and the movable body 22 together define a space. The movable body 22 penetrates the oil passage 11 , and the elastic member 30 is disposed in the space, and the elastic member 30 connects the extension portion 123 and the movable body 22 respectively.

[0068] In the above embodiment, the elastic member 30 is arranged in the space defined by the inner wall of the oil passage 11, the extension portion 123 and the movable body 22. The space defined by the inner wall of the oil passage 11, the extension portion 123 and the movable body 22 has a large volume, which facilitates the assembly of the bypass valve 100. At the same time, the elastic member 30 is immersed in the oil to prevent the elastic member 30 from being oxidized, thereby increasing the service life.

[0069] like Figure 5 As shown, the oil filter structure 1000 of a vehicle according to an embodiment of the utility model includes: a filter element 200 and a bypass valve 100 .

[0070] The filter element 200 is provided with an oil outlet passage 201. The bypass valve 100 is the bypass valve 100 mentioned above, and the bypass valve 100 is provided on the filter element 200. When the movable member 20 is located at the avoidance position, the oil passage 11 is connected to the oil outlet passage 201.

[0071] Among them, the filter element 200 is used to filter the engine oil, such as filtering the dust in the engine oil and the metal particles generated by mechanical friction. The oil outlet channel 201 on the filter element 200 is connected to the engine. The engine oil filtered by the filter element 200 is supplied to the engine to protect the engine.

[0072] It is understandable that the filter element 200 gradually becomes clogged after working for a period of time, causing the oil pressure to increase. When the pressure rises to a certain value, the filter element 200 will be damaged due to the pressure. At this time, the impurities filtered in the early stage will directly enter the lubrication system with the oil, and then cause abnormal mechanical wear or cylinder pulling problems of the engine. In the embodiment of the utility model, a bypass valve 100 is provided. At this time, the bypass valve 100 will open to release pressure, the movable part 20 will move to the avoidance position, and the oil channel 11 will be connected to the oil outlet channel 201, so that the oil flows into the oil channel through the bypass valve 100 for lubrication, avoiding the above-mentioned problems.

[0073] According to the vehicle oil filter structure 1000 of the embodiment of the utility model, a movable part 20 with a pressure-bearing surface 21 is provided, and the surface of the movable part 20 in contact with the oil space is the pressure-bearing surface 21. The pressure of the oil acts on the entire pressure-bearing surface 21. Even if the oil pressure changes slightly, the part of the movable part 20 in contact with the oil is the pressure-bearing surface 21, and the movable part 20 will also be subject to a larger pressure change, thereby improving the sensitivity of the bypass valve 100.

[0074] like Figure 5 As shown, in some embodiments, the oil outlet channel 201 extends along the axial direction of the filter element 200 , and the bypass housing 10 is at least partially disposed in the oil outlet channel 201 .

[0075] The bypass housing 10 is inserted into the oil outlet passage 201 on the filter element 200 . The bypass housing 10 may be completely located in the oil outlet passage 201 , or may be partially located in the oil outlet passage 201 .

[0076] In the above embodiment, by inserting at least part of the bypass housing 10 into the oil outlet passage 201 on the filter element 200, the bypass housing 10 and the filter element 200 at least partially overlap in the axial direction, thereby making the overall size smaller and more compact.

[0077] like Figure 5As shown, in some embodiments, the vehicle's oil filter structure 1000 also includes: an outer shell 300, the outer shell 300 is sleeved on the filter element 200 and the bypass valve 100, the filter element 200 is provided with a first snap-fit ​​portion 202, the bypass shell 10 is provided with a second snap-fit ​​portion 13, the first snap-fit ​​portion 202 and the second snap-fit ​​portion 13 jointly define a snap-fit ​​space 2021, and a third snap-fit ​​portion 301 is provided in the outer shell 300, and the third snap-fit ​​portion 301 is provided in the snap-fit ​​space 2021.

[0078] The buckle space 2021 is disposed between the first buckle portion 202 and the second buckle portion 13 , and the third buckle portion 301 on the housing 300 extends into the buckle space 2021 , and the third buckle portion 301 contacts the first buckle portion 202 and the second buckle portion 13 at the same time.

[0079] In the above embodiment, the first snap-in portion 202 and the second snap-in portion 13 are used to jointly define a snap-in space 2021, and the third snap-in portion 301 extends into the snap-in space 2021. The third snap-in portion 301 is snapped with the second snap-in portion 13 and the first snap-in portion 202 respectively, so that the outer shell 300, the filter element 200 and the bypass shell 10 are combined into one, which improves stability, and has a simple and durable structure and is easy to assemble.

[0080] like Figure 6 As shown, in some embodiments, the oil filter structure 1000 further includes: a base 400 , and the housing 300 is threadedly connected to the base 400 .

[0081] In some specific embodiments, a sealing gasket 302 is provided between the base 400 and the housing 300 to improve the sealing performance.

[0082] In some specific embodiments, the filter element 200 is provided with filter paper to reduce the cost.

[0083] The vehicle according to the embodiment of the present utility model comprises the above-mentioned vehicle oil filter structure 1000.

[0084] According to the vehicle of the embodiment of the utility model, a movable part 20 with a pressure-bearing surface 21 is provided, and the surface of the movable part 20 in contact with the oil space is the pressure-bearing surface 21.
