[0065] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.
[0066] According to the first aspect of this application, referring to Figures 1 to 4 The present disclosure provides an engine 100 including a body 110 and an oil pan 120 .
[0067] The main body 110 is formed with a chamber (not shown) for accommodating the piston and a lubrication channel (not shown) for holding lubricating oil. The oil pan 120 is connected to the main body 110 and has an oil reservoir 120a connected to the lubrication channel for collecting and storing lubricating oil. When the engine 100 is started, the oil pump draws lubricating oil from the oil pan 120 and delivers it through the lubrication channel to the various lubricated components of the engine 100, ensuring normal operation of the engine 100.
[0068] The body 110 further has a pipeline channel 110 a , which is connected to the oil storage tank 120 a , thereby connecting the oil storage tank 120 a with the outside.
[0069] According to the above technical solution, a pipeline channel 110a is provided in the main body 110 of the engine 100, which is connected to the oil storage tank 120a of the oil pan 120. When the oil is drained, an oil extraction pipeline 310 (a hose or a hard pipe) can be extended into the oil storage tank 120a through the pipeline channel 110a to extract the lubricating oil in the oil pan 120, so that the oil draining operation is not affected by the spatial position of the oil pan 120, and the operation is convenient.
[0070] In some embodiments, reference Figure 4 and Figure 8 , the pipeline channel 110a at least partially extends along the depth direction of the oil storage tank 120a.
[0071] It will be appreciated that the conduit channel 110a has a proximal end 110b and a distal end 110c. The proximal end 110b communicates with the oil reservoir 120a, while the distal end 110c opens the conduit channel 110a to the outside. The distance between the distal end 110c of the conduit channel 110a and the oil reservoir 120a in a first direction Z is greater than the distance between the proximal end 110b of the conduit channel 110a and the oil reservoir 120a in the first direction Z. The first direction Z is parallel to the depth of the oil reservoir 120a.
[0072] The first direction Z herein indicates the up-down direction only for the convenience of describing the specific embodiments of this application. There is no absolute correspondence between the first direction Z and the up-down direction. Similarly, there is no absolute correspondence between the second direction X and the left-right direction, and the third direction Y and the front-back direction. Furthermore, the first direction Z, the second direction X, and the third direction Y in this application are merely intended to express relative positional relationships; they merely indicate approximate orientations, not absolute geometric relationships.
[0073] Because the pipe passage 110a at least partially extends along the depth of the oil reservoir 120a, the distal pipe opening 110c can be positioned away from the oil reservoir 120a, minimizing the impact of the spatial position of the oil pan 120 on the distal pipe opening 110c. This allows for greater flexibility in the placement of the distal pipe opening 110c. Furthermore, the distal pipe opening 110c can be positioned at a higher position, providing ample operating space and facilitating oil extraction.
[0074] In some embodiments, reference Figure 4 and Figure 8 , at least a portion of the projection of the pipeline channel 110a along the first direction Z is inside the projection of the oil storage tank 120a along the first direction Z.
[0075] It can be understood that the pipeline passage 110a is directly opposite to the oil storage tank 120a in the up-down direction, which reduces the extension path of the pipeline passage 110a.
[0076] By adopting such a solution, the position of the pipeline channel 110a is limited, and the number of bends and the extension length of the oil extraction pipeline 310 in the pipeline channel 110a are reduced when the oil extraction pipeline 310 is extended, which is conducive to the oil extraction pipeline 310 entering the oil storage tank 120a and facilitates operation.
[0077] In some embodiments, reference Figure 7 and Figure 8 The proximal end 110b of the pipeline channel 110a is arranged corresponding to the deepest part of the oil storage tank 120a.
[0078] It can be understood that the deepest point of the oil storage tank 120a is the lowest point of the oil storage tank 120a in the up-down direction.
[0079] With this solution, the proximal pipe opening 110b is arranged corresponding to the deepest point of the oil storage tank 120a, so that the oil extraction pipeline 310 can extend into the lowest point of the oil storage tank 120a, ensuring that the lubricating oil in the oil pan 120 can be completely extracted.
[0080] In some embodiments, reference Figures 1 to 4 The main body 110 includes a cylinder block 111 and a timing cover 112 .
[0081] The cylinder block 111 forms a receiving cavity and a lubrication channel; the timing cover 112 is coupled to the side of the cylinder block 111 and connected to the cylinder block 111 , and is at least used to protect the timing gear and chain of the engine 100 .
[0082] The “combination” in this application can be understood as a method of fixing by welding, detachable connection, integral molding, etc.
[0083] As an alternative, refer to Figures 1 to 4 The pipeline passage 110a is formed inside the timing cover 112. With this solution, the pipeline passage 110a is integrated into the timing cover 112, which reduces the space for arranging the pipeline passage 110a separately and makes the whole compact.
[0084] As another optional solution, the pipeline channel 110 a may be formed in the cylinder body 111 , and after the oil pan 120 is connected to the cylinder body 111 , the pipeline channel 110 a is connected to the oil storage tank 120 a .
[0085] In some embodiments, reference Figure 1 and Figure 2 , at least a portion of the projection of the timing cover 112 in the first direction Z overlaps with the projection of the oil pan 120 in the first direction Z. This arrangement ensures that the pipeline passage 110a can communicate with the oil reservoir 120a, and the oil pan 120 can support the timing cover 112, thereby improving the stability of the oil pan 120 and preventing misalignment between the pipeline passage 110a and the oil reservoir 120a.
[0086] In some embodiments, reference Figure 4 and Figure 8 The timing cover 112 has a first mounting surface 112 a and a second mounting surface 112 b .
[0087] The first mounting surface 112a contacts and cooperates with the cylinder body 111 to achieve positioning of the timing cover 112 on the cylinder body 111 and sealing with the cylinder body 111. The second mounting surface 112b contacts and cooperates with the oil pan 120 to achieve sealing with the oil pan 120.
[0088] In some embodiments, at least a portion of the cross-sectional profile of the pipeline channel 110 a perpendicular to the first direction Z is formed by an arc. This configuration facilitates the placement of the oil extraction pipeline 310 and reduces resistance to the oil extraction pipeline 310 .
[0089] It is understood that the cross-sectional profile of the pipeline channel 110 a is one of circular, semicircular, or fan-shaped, etc. The cross-sectional profile can be specifically designed according to the structure of the timing cover 112 .
[0090] As a preferred solution, the cross-sectional profile of the pipeline channel 110 a is semicircular, which facilitates demolding of the timing cover 112 during casting.
[0091] In some embodiments, the diameter of the arc ranges from 6 to 15 mm. Such a diameter parameter is used to facilitate the placement of the oil extraction pipeline 310 into the pipeline channel 110 a while avoiding affecting the structural strength and size of the timing cover 112 .
[0092] In some embodiments, reference Figure 4 , the pipe passage 110a penetrates the timing cover 112. That is, the pipe passage 110a penetrates the timing cover 112 in the up-down direction. Adopting such a solution can increase the rigidity of the timing cover 112 and improve the modal.
[0093] In some embodiments, reference Figure 5 and Figure 6 The engine 100 further includes a blocking member 131 .
[0094] The blocking member 131 is disposed at the distal end 110 c of the pipeline passage 110 a . The blocking member 131 is detachably connected to the timing cover 112 and is used to block the pipeline passage 110 a when the engine 100 is in normal use.
[0095] Optionally, the blocking member 131 may be a screw plug, which is threadedly connected and fixed to the timing cover 112 .
[0096] In some embodiments, reference Figure 5 and Figure 6 The engine 100 further includes a gasket 132. The gasket 132 is disposed between the blocking member 131 and the timing cover 112, and is sleeved onto the blocking member 131. The provision of the gasket 132 improves the tightness and stability of the connection, and, in conjunction with the blocking member 131, facilitates removal for maintenance and repair and allows for multiple uses.
[0097] The present disclosure exemplarily describes at least a portion of the oil draining operation process of the engine 100:
[0098] Reference Figure 9 During maintenance of the engine 100, after removing the sealing member 131, an oil extraction pipe 310 is extended through the pipe passage 110a to the bottom of the oil pan 120 and filled with engine oil. The distance A between one end of the oil extraction pipe 310 and the lowest point of the oil storage tank 120a is 2-6 mm. The other end of the oil extraction pipe 310 is connected to the oil extraction pump 320, thereby extracting the lubricating oil in the oil pan 120.
[0099] According to a second aspect of the present disclosure, a power assembly 10 is provided. The power assembly 10 includes the aforementioned engine 100 and a drive motor 210 .
[0100] The drive motor 210 is used to convert electrical energy into driving force output. Its specific operating method adopts existing principles and is not further described. The projection of the engine 100 in the first direction Z (i.e., the vertical direction) and the projection of the drive motor 210 in the first direction Z at least partially overlap, and the oil reservoir 120a is located between the accommodating cavity and the drive motor 210.
[0101] Since the oil pan 120 is located between the driven motor 210 and the engine 100, the arrangement position of the oil drain hole is limited. In the present application, by setting the pipeline channel 110a, the oil drain operation is not affected by the driving motor 210 and the engine 100.
[0102] The power assembly 10 has all the beneficial effects of the above-mentioned engine 100 , which will not be described in detail in this disclosure.
[0103] In some embodiments, reference Figures 1 to 2 The powertrain 10 further includes: a generator 220 .
[0104] Generator 220 is used to convert at least a portion of the driving force of engine 100 into electrical energy. Its specific operating principles are based on existing principles and will not be further described. Generator 220 is arranged with the engine 100 in the second direction X (i.e., the front-to-back direction) and is connected to the engine 100. The projection of generator 220 in the first direction Z (i.e., the vertical direction) at least partially overlaps with the projection of drive motor 210 in the first direction Z. This arrangement enables a high degree of integration of powertrain 10.
[0105] In some embodiments, reference Figures 1 to 2 The powertrain 10 is mounted to the front compartment of the vehicle 1 via a frame 230 arranged in the third direction Y (i.e., the left-right direction). That is, the engine 100 is located at a higher position in the front compartment, so that the distal nozzle 110c is also located at a higher position in the front compartment, which facilitates the oil draining operation during maintenance.
[0106] According to the third aspect of the present disclosure, referring to Figure 10 , providing a vehicle 1, which includes the above-mentioned power assembly 10, and the vehicle 1 has all the beneficial effects of the above-mentioned power assembly 10, which will not be repeated in this disclosure.
