[0026] Reference below Figure 1-Figure 2 The oil pan 100 according to the embodiment of the present invention is described. A side oil shell 5 is connected to one side of the main shell 1, and does not affect the size of the engine mounting surface 12 of the main shell 1, ensuring that the size of the engine is within the original design range. At the same time, adding the side oil shell 5 on the outside can increase the oil storage capacity; in addition, the filter oil inlet channel 3 and the filter oil outlet channel 4 connected to the oil filter 2 are arranged in the first oil storage chamber 11 of the main shell 1, to avoid oil leakage to the outside of the oil pan 100 and affect the user's usage perception. Compared with similar products, the outstanding advantage of the structure is that it can effectively reduce the channels for oil leakage to the outside; the oil pan 100 is not just a container for storing oil, but can more realize the functional requirements required by other parts, such as part installation, oil channels, part sealing, etc. The highly integrated oil pan 100 can reduce the design difficulty of auxiliary parts and reduce the number of parts.

[0027] like Figure 1 and Figure 2 As shown, an oil pan 100 according to an embodiment of the present invention includes a main shell 1 and a side oil shell 5 .

[0028] Among them, a first oil storage chamber 11 is provided in the main shell 1, the upper part of the main shell 1 includes an engine mounting surface 12, and a mounting port 15 is provided on the side of the main shell 1; the side oil shell 5 is installed on the outside of the main shell 1 at the mounting port 15, and the side oil shell 5 is provided with a second oil storage chamber, and the second oil storage chamber is connected to the first oil storage chamber 11.

[0029] In practice, the main housing 1 is the oil pan at the bottom of the engine. The main function of the oil pan is to store the oil required for the normal operation of the engine, to ensure that the oil collector can absorb oil normally under various conditions, and to meet the needs of some customers with off-road needs. When climbing off-road, the oil collector can still absorb oil normally, that is, it is necessary to ensure that the amount of oil is sufficient, and it is necessary to meet the design requirement that the oil level is ≥8mm away from the crankshaft connecting rod envelope when the vehicle is in a horizontal state.

[0030] In an embodiment of the present invention, the first oil storage chamber 11 of the main housing 1 is used to store engine oil, and the engine oil is connected to the oil channel inside the engine to lubricate various parts of the engine. When the engine stops, the engine oil circulating in the oil circuit will flow back to the main housing 1 under the action of gravity, thereby achieving the recycling of the engine oil; and the main housing 1 is provided with multiple side surfaces, a mounting port 15 is provided on one side surface of the main housing 1, and a side oil shell 5 is installed at the mounting port 15. The side oil shell 5 has only one open port, and other parts of the side oil shell 5 are closed, only the open port is opposite to the mounting port 15, and the side oil shell 5 is connected to the main housing 1 at the mounting port 15, such as the side oil shell 5 can be welded at the mounting port 15 or detachably connected.

[0031] In addition, the side oil shell 5 can be made of plastic, stamped steel plate or cast aluminum, and can be appropriately selected based on weight, cost and manufacturability.

[0032] It should be noted that the position of the mounting port 15 is staggered with the position of the engine mounting surface 12, and they do not affect each other. That is, when installing the engine on the engine mounting surface 12, there is no need to change the size of the engine mounting surface 12, and the original engine can be installed. At the same time, it can be connected with the first oil storage chamber 11 of the main shell 1 through the second oil storage chamber of the side oil shell 5 to achieve the effect of increasing the oil storage capacity, thereby meeting the normal demand for oil storage capacity of the oil pan; if the vehicle is in a horizontal state, the design of the oil pan 100 of the embodiment of the utility model has a lower oil level than the original one that holds the same amount of oil, thereby being able to meet the distance requirement that the oil level of the vehicle is ≥8mm from the crankshaft connecting rod envelope when the vehicle is in a horizontal state.

[0033] Moreover, in the case where the oil collector is arranged at the front end of the engine, and the oil flows to the rear end when the vehicle climbs a slope and cannot be collected, after increasing the oil storage capacity by adding the side oil shell 5 and ensuring that the oil level submerges the oil suction port of the oil collector, the vehicle can climb a larger slope compared to the solution without adding the side oil shell 5, thereby improving the performance of the entire vehicle and enhancing the competitiveness of the product.

[0034] In some embodiments, a plurality of first mounting holes 14 are provided on the periphery of the mounting port 15, the side oil shell 5 includes a connecting flange 51, the connecting flange 51 is provided with a plurality of second mounting holes 511, and each first mounting hole 14 and the corresponding second mounting hole 511 are connected by a connecting member 6 to connect the side oil shell 5 to the main shell 1.

[0035] At this time, it is equivalent to that the main shell 1 realizes flange connection with the connecting flange 51 of the side oil shell 5 at the installation port 15. By setting the side oil shell 5 as the connecting flange 51, it can increase the connection area between the side oil shell 5 and the main shell 1, thereby ensuring the connection reliability, and can also make the connecting flange 51 cover around the installation port 15, so that the installation port 15 is opposite to the open port of the side oil shell 5, ensuring that the installation port 15 and the open port of the side oil shell 5 are effectively connected.

[0036] Moreover, the connecting member 6 is a connecting bolt, each connecting bolt corresponds to a first mounting hole 14 and a second mounting hole 511, and multiple connecting members 6 can be evenly distributed on the connecting flange 51 of the side oil shell 5 and the periphery of the mounting port 15, thereby ensuring the uniformity of the force of the connection and, at the same time, ensuring the reliability of the connection.

[0037] In some embodiments, sealant is provided between the outer periphery of the mounting opening 15 and the connecting flange 51 to seal the side oil casing 5 and the main housing 1 .

[0038] For example, polyurethane sealant, silicone sealant, fluororubber, etc. are provided between the outer periphery of the mounting opening 15 and the connecting flange 51. The polyurethane sealant has good anti-loosening performance and can completely replace traditional spring washers and flat washers, especially in the key positions of the bolts. It can give full play to its unique role and prevent the bolts from loosening due to vibration and impact, while ensuring the sealing of the installation between the side oil shell 5 and the shell main shell 1, thereby preventing the oil in the oil pan 100 from leaking.

[0039] In some embodiments, the outside of the oil pan 100 also includes a filter mounting portion 13, which is used to install the oil filter 2. The first oil storage chamber 11 of the main shell 1 is provided with a filter oil inlet channel 3 and a filter oil outlet channel 4. One end of the filter oil inlet channel 3 is used to connect to the oil cooler and the other end is used to connect to the oil filter 2. One end of the filter oil outlet channel 4 is used to connect to the main oil channel of the engine and the other end is used to connect to the oil filter 2.

[0040] In practice, the first oil storage chamber 11 in the oil pan 100 can be connected to the oil collector, which is used to collect the oil in the first oil storage chamber 11, and the oil collector is connected to one end of the oil cooler, which is not shown in the figure. The other end of the oil cooler is connected to the filter oil inlet channel 3 in the main shell 1. The main function of the oil cooler is to make the oil temperature of the oil close to the ideal value to ensure the normal operation of the engine and the health of various components. The cooled oil is filtered through the oil filter 2. The function of the oil filter 2 is to remove impurities such as dust, metal particles, carbon deposits and soot particles in the oil. By filtering some mechanical impurities and colloids, the lubricating oil is kept clean and its service life is extended, thereby protecting the engine; and the oil filtered by the oil filter 2 can be connected to the main oil channel of the engine, and the oil is lubricated to various components of the engine through the main oil channel.

[0041] However, in the embodiment of the present utility model, the filter oil inlet channel 3 and the filter oil outlet channel 4 are arranged in the first oil storage chamber 11 of the shell. After the filter oil inlet channel 3 and the oil outlet 41 of the oil cooler are sealed and connected with a sealing ring, and the filter oil outlet channel 4 and the main oil channel of the engine are connected with a sealing ring, assuming that there is a leak at the connection between the filter oil inlet channel 3 and the oil cooler or the connection between the filter oil outlet channel 4 and the main oil channel of the engine, the leaked oil can flow directly into the first oil storage chamber 11 of the main shell 1, thereby preventing the oil from leaking to the outside and avoiding panic to the user.

[0042] In some embodiments, the oil filter 2 is mounted on the bottom of the main housing 1 in the up-down direction, and the oil filter inlet channel 3 and the oil filter outlet channel 4 both extend in the up-down direction within the first oil storage chamber 11 .

[0043] That is to say, the extension direction of the filter oil inlet channel 3 and the filter oil outlet channel 4 is consistent with the height direction of the oil filter 2, and the oil filter 2 is located at the bottom of the main shell 1, so that the filter oil inlet channel 3 and the filter oil outlet channel 4 are conveniently connected to the oil filter 2 in a shorter path, thereby improving the flow efficiency of the oil; moreover, the filter oil inlet channel 3 is provided with an oil inlet port 31 open upward, and the oil cooler can be arranged on the upper side of the main shell 1, which is convenient for connection with the oil cooler, and the filter oil outlet channel 4 is provided with an oil outlet port 41 open upward, and the filter oil outlet channel 4 is connected to the main oil channel of the engine. The upward open oil outlet port 41 can be conveniently connected to the main oil channel of the engine, thereby shortening the connection path of the lubricating oil circuit and improving the oil lubrication efficiency.

[0044] In some embodiments, a portion of the oil filter 2 is located below the main housing 1 and a portion thereof protrudes toward the outer side of the main housing 1 .

[0045] Reference Figure 1As shown, an avoidance space is provided at the bottom of the main shell 1, and the avoidance space is open toward the bottom and toward one side. The oil filter 2 is partially hidden in the avoidance space at the bottom of the main shell 1, and partially exposed on one side of the main shell 1, thereby improving the integration of the main shell 1 and the oil filter 2 and saving space. At the same time, the oil filter 2 is equivalent to supporting the main shell 1, thereby improving the stability of the oil pan 100.

[0046] In some embodiments, the filter oil inlet channel 3 and the filter oil outlet channel 4 are arranged in the first oil storage chamber 11 near the corner, and the oil filter 2 is located outside the corner of the main housing 1.

[0047] First, the filter oil inlet channel 3 needs to be connected to the oil cooler, and the oil cooler is located on the outer side of the main shell 1, and the outlet of the oil cooler is connected to the filter oil inlet channel 3. The filter oil inlet channel 3 is set at a corner position in the first oil storage chamber 11, which can facilitate the connection of the filter oil inlet channel 3 to the oil cooler and reduce the connection path.

[0048] In addition, the main oil channel of the engine generally extends along the length direction of the engine, and the main oil channel is connected to multiple branches, and the various components of the engine are lubricated through the multiple branches, and the filter oil outlet channel 4 can be connected to one end of the main oil channel in the length direction, so the filter oil outlet channel 4 is also arranged at a corner position to facilitate connection with the end of the main oil channel; moreover, the filter oil inlet channel 3 and the filter oil outlet channel 4 are both arranged at a corner position of the first oil storage chamber 11, which can avoid resistance to the flow of engine oil or diversion of engine oil when they are arranged in the middle or other positions of the main housing 1.

[0049] In some embodiments, the outer side of the main housing 1 includes a first side 16, a second side 17 and a third side 18, the side oil shell 5 is installed on the first side 16 and a portion of the oil filter 2 protrudes toward the second side 17, and the third side 18 is also provided with a crankshaft rear oil seal mounting seat 7 and a transmission mounting surface 8, the crankshaft rear oil seal mounting seat 7 is used to fix and support the crankshaft rear oil seal, and the transmission mounting surface 8 is used to install the transmission.

[0050] That is, the oil filter 2 and the side oil shell 5 are respectively arranged on different sides of the main housing 1, which can not only ensure the connection integration of the side oil shell 5, the oil filter 2 and the main housing 1, but also make the different structures installed in the main housing 1 reasonably arranged; at the same time, the crankshaft rear oil seal mounting seat 7 and the transmission mounting surface 8 are set on the third side 18 of the oil pan 100. The crankshaft rear oil seal mounting seat 7 is used to fix and support the crankshaft rear oil seal, and the crankshaft rear oil seal is connected to the crankshaft. The main function of installing the crankshaft rear oil seal on the oil pan 100 of the engine is to prevent oil leakage and external impurities from entering the crankcase.

[0051] In addition, the engine is generally installed adjacent to the transmission to achieve power transmission. Therefore, a transmission mounting surface 8 is provided on the third side 18 of the engine to provide a connection portion for the installation of the engine and the transmission, thereby improving the reliability of the connection between the engine and the transmission. In other words, at this time, the main housing 1 not only serves to store engine oil, but also enables the integrated installation of various components, making the structure of the engine more compact.

[0052] In some embodiments, the oil pan 100 further includes an oil dipstick conduit mounting portion 9 , which is located outside the engine mounting surface 12 and communicates with the first oil storage chamber 11 .

[0053] Among them, an oil dipstick conduit mounting hole is provided on the oil dipstick conduit mounting portion 9, and the oil dipstick conduit is installed at the oil dipstick conduit mounting hole. The oil dipstick conduit is mainly used to install the oil dipstick, and the function of the oil dipstick is to measure the oil level of the engine through the oil dipstick conduit; the oil dipstick conduit mounting portion 9 is located in the middle position in the length direction of the main shell 1 to improve the accuracy of measuring the oil level. The oil dipstick conduit is used to guide the direction of the oil dipstick; by arranging different mounting portions at different positions of the oil pan 100, the oil pan 100 is used as the mounting surface, which facilitates the integrated installation of various different structures.

[0054] The present utility model also discloses a vehicle, including the above-mentioned oil pan 100, which expands the volume without changing the size of the interface between the oil pan 100 and the cylinder block. After adding the side oil shell 5, the volume can be increased by about 1L. The increased volume at the boundaries of different vehicles is different, which effectively solves the problem of insufficient engine refueling and can improve the climbing grade by about 20% based on the original state of the oil pan 100.
