Description

Technical Field

[0001] The utility model belongs to the technical field of vehicles, and in particular relates to an oil drain port component, an oil pan assembly, an engine assembly and a vehicle. Background Art

[0002] When changing the engine oil during maintenance, if the oil is not drained thoroughly, the impurities in the engine oil will sink to the bottom of the oil pan, affecting the cleanliness of the oil and causing abnormal wear of engine parts. A boss with an internal threaded hole is provided at the drain port of the engine oil pan, and the boss protrudes toward the inner cavity of the oil pan. The oil in the oil pan that is lower than the end face of the boss cannot flow out through the internal threaded hole.

[0003] In the related art, a through hole is provided on the side wall of the boss at one end near the oil drain port. If the aperture of the through hole is small, air blockage will occur, resulting in slow oil draining. Slow oil draining during after-sales maintenance may be easily judged as complete oil draining, thus posing a risk of incomplete oil draining. If the aperture of the through hole is large, the height of the boss may be too high. In addition, the oil drain port needs to be sealed by a plugging member and a sealing gasket. During use, when the sealing gasket is permanently deformed, the sealing structure may easily loosen, resulting in sealing failure. Utility Model Content

[0043] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0044] like Figure 1-Figure 3 As shown, the oil drain port assembly 100 according to the embodiment of the utility model includes a connecting member 2, a limiting member 1 and an elastic member 3.

[0045] The connecting member 2 is located on one side of the oil pan 200 close to the inner cavity, and has a connecting hole 21, which corresponds to the oil drain port 201 of the oil pan 200. One end of the connecting member 2 close to the oil drain port 201 is spaced apart from the oil pan 200 to form a flow channel, which is used to connect the inner cavity and the oil drain port 201. It should be understood that the connecting hole 21 is used to connect with the plugging member 4, so that a portion of the plugging member 4 can pass through the oil drain port 201 and then connect with the connecting member 2, and be fixed at the oil drain port 201 to block the oil drain port 201, and the connecting hole 21 is a threaded hole.

[0046] The limiting member 1 has a first limiting portion 11 and a second limiting portion 12. The first limiting portion 11 extends along the axial direction of the connecting member 2. The first limiting portion 11 and the connecting member 2 are slidably matched in the axial direction of the connecting member 2. The first limiting portion 11 and the connecting member 2 are limited in the circumferential direction of the connecting member. That is, the first limiting portion 11 abuts against the connecting member 2 so that the connecting member 2 can be moved relative to the oil drain port 201 in its axial direction and the circumferential rotation of the connecting member 2 is limited. The second limiting portion 12 can abut against the connecting member 2 to limit the displacement distance of the connecting member 2 in the direction away from the oil drain port 201.

[0047] The elastic member 3 is arranged between the connecting member 2 and the oil pan 200 to provide a force for the connecting member 2 to move away from the oil pan 200. Under the action of the elastic member 3, the connecting member 2 can move in a direction close to the oil drain port 201 or in a direction away from the oil drain port 201. When the oil drain port 201 is opened, the elastic member 3 can push the connecting member 2 to move in a direction away from the oil drain port 201, thereby increasing the spacing distance between the connecting member 2 and the oil drain port 201. At the same time, the flow cross-sectional area of ​​the flow channel is increased, thereby increasing the oil draining speed and the oil emptying effect, thereby preventing the oil and impurities from being deposited in the oil pan 200. When the oil drain port 201 is sealed by the plugging member 4, the plugging member 4 can be connected to the connecting hole 21 of the connecting member 2. At the same time, the axial force of the plugging member 4 acting on the connecting member 2 compresses the elastic member 3, and the connecting member 2 moves in a direction close to the oil drain port 201, thereby reducing the distance between the end of the connecting member 2 away from the oil drain port 201 and the oil drain port 201.

[0048] The elastic member 3 in the embodiment of the utility model is in a compressed state, and can also prevent the blocking member 4 from loosening, thereby preventing the sealing gasket 5 from being permanently deformed due to long-term use and failing to prevent it from loosening.

[0049] Optionally, the elastic member 3 is a spring or a spring sheet, for example, the elastic member 3 is a coil spring. The spring may be one or more. When multiple springs are provided, the multiple springs are arranged at intervals along the circumference of the connecting member 2. Countersunk holes may be provided on the connecting member 2 and / or the oil pan 200 so that at least one end of the spring is provided in the corresponding countersunk hole, thereby limiting the spring.

[0050] The axial direction of the connecting member 2 is the up-down direction shown in the figure.

[0051] like Figure 1-Figure 3As shown, in some embodiments, the connector 2 has a third limiting portion 22, the first limiting portion 11 abuts against the circumferential side wall of the third limiting portion 22, and the second limiting portion 12 can abut against one end of the third limiting portion 22 away from the oil drain port 201. It should be understood that the connector 2 can be a nut or a connecting sleeve with an internal threaded hole. When the limiting member 1 is not easy to directly limit the nut or the connecting sleeve, in order to simultaneously ensure that the nut or the connecting sleeve does not rotate in the circumferential direction, the nut or the connecting sleeve can move in the axial direction, and the nut or the connecting sleeve is constrained in the axial limit displacement distance, the embodiment of the utility model is provided with a third limiting portion 22 on the connector 2, and the third limiting portion 22 is used to abut and limit with the first limiting portion 11 and the second limiting portion 12.

[0052] Optionally, the third limiting portion 22 can be a flange-shaped positioning plate provided on the connecting member 2, the positioning plate having a circumferential side surface, and the end of the positioning plate away from the oil drain port 201 having an axial limiting surface, the circumferential side surface abuts against the first limiting portion 11 of the limiting member 1, thereby limiting the rotation of the connecting member 2, and at the same time, the connecting member 2 can use the first limiting portion 11 as a guide to move axially, and the axial limiting surface abuts against the second limiting portion 12, thereby limiting the extreme displacement distance of the connecting member 2 in the direction away from the oil drain port 201.

[0053] For example, the positioning plate may be a rectangular plate, a pentagonal plate, an elliptical plate, etc., and at least a portion of the circumferential side surface of the positioning plate can limit the rotation of the connecting member 2 after abutting against the first limiting portion 11 .

[0054] Optionally, the third limiting portion 22 is a plurality of positioning blocks spaced apart on the circumferential side wall of the connecting member 2, the plurality of positioning blocks abut against the first limiting portion 11, limit the rotation of the connecting member 2, and enable the connecting member 2 to move along its axial direction, and the end of the positioning block away from the oil drain port 201 abuts against the second limiting portion 12, limit the ultimate displacement distance of the connecting member 2 in the direction away from the oil drain port 201.

[0055] like Figure 1-Figure 3 As shown, in some embodiments, the third limiting portion 22 is disposed at one end of the connecting member 2 close to the oil drain port 201. It should be understood that the third limiting portion 22 is disposed at one end of the connecting member 2 close to the oil drain port 201, and when the axial height of the connecting member 2 and the maximum distance between the connecting member 2 and the oil drain port 201 are constant, the height of the connecting member 2 and the limiting member 1 protruding toward the inner cavity of the oil pan 200 can be reduced, and the flow cross-sectional area of ​​the flow channel can be increased.

[0056] In some embodiments, one end of the elastic member 3 abuts against the connecting member 2 , and the other end of the elastic member 3 abuts against the oil pan 200 , thereby simplifying the assembly structure and improving the assembly efficiency.

[0057] Alternatively, one end of the elastic member 3 is fixedly connected to the connecting member 2, and the other end of the elastic member 3 is fixedly connected to the oil pan 200, which can improve the structural stability between the elastic member 3, the connecting member 2 and the oil pan 200, improve the positioning accuracy, and avoid the deviation of the alignment relationship between the components.

[0058] Alternatively, one end of the elastic member 3 is abutted against one of the connecting member 2 and the oil pan 200, and the other end of the elastic member 3 is fixedly connected to the other of the connecting member 2 and the oil pan 200, which can simplify the assembly structure and improve the assembly efficiency while improving the structural stability and positioning accuracy between the components.

[0059] For example, the elastic member 3 is fixedly connected to the connecting member 2, and the elastic member 3 abuts against the oil pan 200. At this time, the limit member 1 can limit the circumferential direction of the connecting member 2, and the elastic member 3 will not deviate or swing circumferentially due to the fixed connection relationship with the connecting member 2.

[0060] like Figure 1-Figure 3 As shown, in some embodiments, there are multiple limit members 1, and the multiple limit members 1 are arranged along the circumference of the connecting member 2, and at least some adjacent limit members 1 are spaced apart, so that a sliding track can be formed between the multiple limit members 1 for the connecting member 2 to approach or move away from the oil pan 200 without blocking the flow channel.

[0061] The number of the limiting members 1 may be 2, 3 or 4.

[0062] Optionally, the limit member 1 can be a limit plate extending along the axial direction of the connecting member 2, and the side of the limit plate facing the connecting member 2 is a first limit portion 11, and the first limit portion 11 abuts against the circumferential side of the third limit portion 22, so as to play a guiding and limiting role. The top of the limit plate has an end plate as a second limit portion 12. In the up and down directions shown in the figure, the limit plate is an inverted L-shape as a whole, and the second limit portion 12 is used to abut against the end of the third limit portion 22 away from the oil drain port 201.

[0063] Optionally, the limit member 1 is a guide rod extending along the circumference of the connecting member 2, the outer circumferential surface of the guide rod serves as the first limit portion 11, an end cap is arranged on the top of the guide rod, the end cap serves as the second limit portion 12, a guide hole is provided on the connecting member 2 as the third limit portion 22, the guide rod is arranged in the guide hole, and the guide rod and the wall surface of the guide hole are fitted and abutted to prevent the connecting member 2 from circumferential rotation, and the end cap is abutted against the end of the guide hole away from the oil drain port 201 to constrain the limit displacement distance of the connecting member 2 in its axial direction.

[0064] In some embodiments, the limiting member 1 is in the shape of a ring sleeve, and is disposed on the outside of the connecting member 2 . A through hole is disposed between the end of the limiting member 1 close to the oil drain port 201 and the oil pan 200 .

[0065] That is to say, the limiting member 1 can be a limiting sleeve in the shape of a ring, and the limiting sleeve is sleeved on the outside of the connecting member 2. For example, when the connecting member 2 is a hexagonal nut, the inner hole of the limiting sleeve can be a hexagonal hole. For another example, when the connecting member 2 is a connecting sleeve with a circular cross-section, the third limiting portion 22 on the connecting member 2 can be set as a rectangular plate, and the inner hole of the limiting member 1 is set as a rectangular hole. The side wall of the hexagonal hole and the side wall of the rectangular hole in the above structure serve as the first limiting portion 11. In order to constrain the axial limit displacement distance of the connecting member 2, a limiting ring extending toward the center of the limiting sleeve is set at the end away from the oil drain port 201, and the limiting ring serves as the second limiting portion 12.

[0066] The through hole is used to connect the inner cavity of the oil pan 200 and the flow channel between the connecting piece 2 and the oil pan 200, so that the oil in the oil pan 200 can flow out from the oil drain port 201 after passing through the through hole and the flow channel, thereby improving the oil draining effect and preventing the oil or impurities from being deposited in the oil pan 200.

[0067] like Figure 4 As shown, the oil drain port assembly 100 according to the embodiment of the utility model includes a connecting member 2 and an elastic member 3.

[0068] The connecting member 2 is located on a side of the oil pan 200 close to the inner cavity, and has a connecting hole 21, which corresponds to the oil drain port 201 of the oil pan 200. It should be understood that the connecting hole 21 is used to connect with the blocking member 4, so that a portion of the blocking member 4 can pass through the oil drain port 201 and then connect with the connecting member 2, and be fixed at the oil drain port 201 to block the oil drain port 201, and the connecting hole 21 is a threaded hole.

[0069] One end of the connector 2 near the oil drain port 201 is spaced apart from the oil pan 200 to form a flow channel, which is used to connect the inner cavity and the oil drain port 201. One end of the elastic member 3 is fixedly connected to the connector 2, and the other end of the elastic member 3 is fixedly connected to the oil pan 200. The connector 2 is movable relative to the oil pan 200 in its axial direction. It should be understood that, unlike the other embodiments described above, the limiting member 1 may not be provided in this embodiment. The two ends of the elastic member 3 are respectively fixedly connected to the connector 2 and the oil pan 200. The connector 2 can be pulled by the elastic member 3 to achieve axial limiting, ensuring that the connector 2 and the elastic member 3 do not separate from the oil pan 200. The elastic member 3 can also use its own rigidity to limit the circumferential rotation of the connector 2, so as to avoid the sealing member 4 being unable to be effectively connected to the sealing member 4 due to the self-rotation of the connector 2 when the sealing member 4 is connected to the connector 2.

[0070] When the oil drain port 201 is opened, the elastic member 3 can push the connecting member 2 to move in the direction away from the oil drain port 201, thereby increasing the spacing distance between the connecting member 2 and the oil drain port 201. At the same time, the flow cross-sectional area of ​​the flow channel is increased, thereby improving the oil draining speed and the oil emptying effect, and preventing the oil and impurities from being deposited in the oil pan 200. When the oil drain port 201 is sealed by the sealing member 4, the sealing member 4 can be connected to the connecting hole 21 of the connecting member 2, and at the same time, the axial force of the sealing member 4 on the connecting member 2 is used to compress the elastic member 3, and the connecting member 2 will move in the direction close to the oil drain port 201, which can not only reduce the distance between the end of the connecting member 2 away from the oil drain port 201 and the oil drain port 201, but also the elastic member 3 in the compressed state can prevent the sealing member 4 from loosening.

[0071] In some embodiments, the oil drain port assembly 100 further includes a stopper 1; the stopper 1 is connected to the oil pan 200, and the stopper 1 has a first stopper 11, the first stopper 11 extends along the axial direction of the connecting member 2, and the first stopper 11 abuts against the connecting member 2 to allow the connecting member 2 to be movable in its axial direction and to limit the circumferential rotation of the connecting member 2. It should be understood that in order to prevent the elastic member 3 from rotating in the circumferential direction during the threaded connection between the plugging member 4 and the connecting member 2, the stopper 1 is provided in the embodiment of the utility model, and the first stopper 11 is used to abut and limit the connecting member 2, thereby ensuring that the elastic member 3 does not bear the circumferential force and improving the structural stability.

[0072] The elastic member 3, the connecting member 2 and the limiting member 1 in the embodiment of the utility model can adopt the same or similar structures as those in the above embodiments, which will not be described in detail here.

[0073] like Figure 5 As shown, the oil pan assembly according to the embodiment of the utility model includes an oil pan 200 and an oil drain port assembly 100 as in any of the above embodiments, the oil drain port assembly 100 is arranged on the side of the oil pan 200 close to the inner cavity, the oil pan 200 has an inner cavity and an oil drain port 201, the oil drain port assembly 100 is connected to the side of the oil pan 200 close to the inner cavity and is arranged corresponding to the oil drain port 201; a sealing member 4 is provided at the oil drain port 201, the sealing member 4 has a column section 41 and an end head 42, the column section 41 is penetrated in the oil drain port 201 and is connected to the connecting hole 21 of the connecting member 2, and the end head 42 is in contact with the side of the oil pan 200 away from the inner cavity.

[0074] It should be understood that the column section 41 of the sealing member 4 has an external threaded section, and the connecting hole 21 of the connecting member 2 is a threaded hole. After the sealing member 4 is threadedly connected to the connecting member 2, the connecting member 2 can compress the elastic member 3, and the connecting member 2 moves toward the oil drain port 201, thereby reducing the height of the connecting member 2 protruding toward the inner cavity of the oil pan 200, and when the oil drain port 201 is opened, the resilience of the elastic member 3 can be utilized to provide a flow channel of sufficient size between the connecting member 2 and the oil pan 200, so as to improve the oil drain efficiency and effect.

[0075] like Figure 5 As shown, in some embodiments, the oil pan 200 further includes a sealing gasket 5, which is disposed between the end head 42 and the oil pan 200. By providing the sealing gasket 5, on the one hand, the sealing effect can be improved to prevent the oil from leaking out from between the sealing member 4 and the oil pan 200, and on the other hand, the elasticity of the sealing gasket 5 can be used to prevent the sealing member 4 from loosening.

[0076] In the embodiment of the utility model, after the sealing gasket 5 is permanently deformed, the elastic member 3 can be used to prevent the blocking member 4 from loosening, thereby improving the stability of the overall structure.

[0077] The engine assembly according to the embodiment of the present utility model includes the oil drain port assembly 100 as in any one of the above embodiments, or the oil pan assembly as in the above embodiments.
