[0046] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0047] The present embodiment provides an engine, which comprises an oil pump and an oil sump assembly 1000. The oil sump assembly 1000 is used in an engine, which functions as a housing enclosing the crankcase as an oil storage structure, prevents impurities from entering, and collects and stores lubricating oil flowing back from each friction surface of the diesel engine, dissipates part of the heat, and prevents oxidation of the lubricating oil.

[0048] In use, the oil pump forms a low pressure when working, generates suction, and extracts oil from the oil sump assembly 1000. The engine further comprises an oil pump oil outlet pipe 2000, which is connected between the oil pump and the body of the engine, and part of the oil in the oil pump can flow to the body of the engine through the oil pump oil outlet pipe 2000.

[0049] As shown in Figure 1 and Figure 2 The present embodiment also provides an oil sump assembly 1000. The oil sump assembly 1000 comprises an oil sump body 100, which has an oil cavity 110 that can be located at any position of the oil sump body 100. The oil pump oil outlet pipe 2000 is used to connect the oil pump and the oil cavity 110. The specific shape of the oil sump body 100 can be set according to requirements, and the present embodiment does not limit this.

[0050] In addition, the oil cavity 110 is located between the oil pump oil outlet pipe 2000 and the body of the engine, and the oil pump delivers oil to the oil cavity 110 through the oil pump oil outlet pipe 2000, and then flows to the body of the engine, enters the main oil passage of the engine, and is used to cool the engine.

[0051] In some embodiments, the oil sump body 100 has a first side wall 120 defining the oil cavity 110, so that the first side wall 120 of the oil sump body 100 is used as one side wall of the oil cavity 110, which is beneficial to simplify the structure.

[0052] In the present utility model, the side wall in the first side wall is different from the concept of bottom wall, which refers to the wall surface of the side of the object, for example, in a cuboid box, the four faces connecting the upper and lower bottom surfaces are side walls, which mainly play a role in enclosing space. The bottom wall refers to the wall surface of the bottom of the object, and the bottom wall usually needs to have a certain bearing capacity because it needs to bear the weight of the entire object.

[0053] In addition, the oil sump body 100 has a second wall 130 defining the oil cavity 110, and the second wall 130 is opposite to the first side wall 120 with respect to the oil cavity 110. The first side wall 120 and the second wall 130 jointly define the oil cavity 110.

[0054] Please continue to refer to Figure 1 and Figure 2The oil sump assembly 1000 further comprises a communication assembly 200. The communication assembly 200 is detachably connected with the first side wall 120 and is arranged in the oil cavity 110. The communication assembly 200 is configured to communicate the oil cavity 110 with the oil pump outlet pipe 2000.

[0055] Specifically, the communication assembly 200 penetrates the first side wall 120 and the second wall 130 from the first side wall 120 to the second wall 130 and is connected with the oil pump outlet pipe 2000.

[0056] When the oil sump body 100 needs to be disassembled, the oil pump outlet pipe 2000 can be separated from the oil sump body 100 by only detaching the communication assembly 200 from the first side wall 120. At this time, the operator can directly disassemble and replace the oil sump body 100. When the oil sump body 100 is disassembled, since the communication assembly 200 is installed on the first side wall 120, the oil sump body 100 only needs to be operated from the side of the oil sump body 100 when disassembling the oil sump body 100, avoiding the disadvantages of disassembling the oil sump body 100 from the bottom of the oil sump body 100, and the operation is more labor-saving and safer.

[0057] In addition, when the oil sump body 100 is disassembled, the oil sump assembly 1000 does not need to drain the engine oil in the oil cavity 110, avoiding the waste of oil liquid and being conducive to saving maintenance and replacement costs.

[0058] The details of the communication assembly 200 of the oil sump assembly 1000 will be described below. Figures 1-6 As shown in

[0059] As shown in Figures 1-6 The communication assembly 200 communicates the oil cavity 110 and the oil pump outlet pipe 2000 through a communication pipe 210. The communication pipe 210 is simple in structure, safe and reliable, and convenient to maintain and replace.

[0060] Specifically, the cross-sectional shape of the communication pipe 210 is the same as that of the oil pump outlet pipe 2000, so as to be connected with the oil pump outlet pipe 2000.

[0061] As shown in Figure 5 As shown in Figure 6 The communication assembly 200 comprises a hollow communication pipe 210. The communication pipe 210 is detachably connected with the first side wall 120 and is arranged in the oil cavity 110. The communication pipe 210 has a port 211 and a through hole 212. The through hole 212 communicates the oil cavity 110 with the inside of the communication pipe 210, and the port 211 is configured to communicate the oil pump outlet pipe 2000.

[0062] Specifically, the connection between the oil pump outlet pipe 2000 and the communication pipe 210 at the port 211 can be that the oil pump outlet pipe 2000 is inserted into the communication pipe 210, or that the oil pump outlet pipe 2000 is sleeved on the communication pipe 210. As the oil flows from the communication pipe 210 to the oil cavity 110, in the present embodiment, the connection between the oil pump outlet pipe 2000 and the communication pipe 210 is that the oil pump outlet pipe 2000 is inserted into the port 211 of the communication pipe 210, which is advantageous to avoid the oil from seeping out of the gap between the oil pump outlet pipe 2000 and the communication pipe 210.

[0063] As an alternative, the through hole 212 penetrates the communication pipe 210 along the flow direction of the oil in the oil cavity 110, so that the inside of the communication pipe 210 is balanced with the pressure in the oil cavity 110, avoiding the inside of the communication pipe 210 generating negative pressure compared with the oil cavity 110, and the resistance generated by the oil flowing from the oil pump outlet pipe 2000 to the oil cavity 110, which is advantageous to ensure that the oil flow is not restricted by the structure of the through hole 212, and does not affect the performance parameters such as the pressure and flow of the oil.

[0064] The extension direction of the oil cavity is at an angle to the axial extension direction of the communication pipe, that is, the flow direction of the oil in the oil cavity is at an angle to the axial extension direction of the communication pipe, for example, 90 degrees.

[0065] In some embodiments, the wall of the communication pipe is at an angle to the first side wall, for example, the wall of the communication pipe is perpendicular to the first side wall, and the through hole 212 is a square through hole. The square through hole 212 is advantageous to expand the communication area between the communication pipe and the oil cavity 110, and further reduce the influence of the communication pipe 210 on the performance parameters such as the pressure and flow of the oil.

[0066] In some embodiments, in the axial direction of the communication pipe 210, the size of the through hole 212 is greater than the size of the oil cavity 110, so as to further expand the communication area between the communication pipe and the oil cavity 110, and reduce the influence of the communication pipe 210 on the performance parameters such as the pressure and flow of the oil.

[0067] As Figure 5As shown, the connecting pipe 210 also has a first end surface 213 located at the port 211, and the oil pump outlet pipe 2000 has a second end surface 2001 at one end inserted into the connecting pipe 210, the second end surface 2001 is located between the first end surface 213 and the side of the second wall 130 away from the oil cavity 110, so that the oil pump outlet pipe can be inserted into the connecting pipe and cannot enter the oil cavity of the oil pan, so that after the connecting pipe 210 is disassembled, the second end surface 213 of the oil pump outlet pipe 2000 is separated from the side of the second wall 130 away from the oil cavity 110, and then the second end surface 213 is directly separated from the oil pan body 100, so as to avoid interference between the oil pump outlet pipe 2000 and the oil pan body 100 when the oil pan body 100 is disassembled, and the oil pan body 100 can be directly disassembled and replaced.

[0068] Optionally, as shown in Figure 5 and Figure 6 The connecting assembly 200 includes a mounting plate 220 and a fixing member 230. The mounting plate 220 is connected to the third end surface 214 of the connecting pipe 210 away from the port 211, and the fixing member 230 is detachably connected to the mounting plate 220 and the first side wall 120, so as to realize the detachable connection between the connecting assembly 200 and the first side wall 120. The connecting mode of the connecting assembly 200 is simple, and is convenient for assembly and disassembly.

[0069] Optionally, the fixing member 230 can be a fastener, such as a bolt or a screw. Both the bolt and the screw are common fasteners, which are simple in structure, convenient to operate, and low in cost. In an example, the fixing member 230 is a bolt, which has higher connection strength and higher structural stability.

[0070] The number of the fixing member 230 can be three, four, five, six or more. The number of the fixing member 230 can be set arbitrarily according to the size and shape of the mounting plate 220.

[0071] As an optional solution, the mounting plate 220 is a thin-walled plate structure, so as to be attached to the outer surface of the first side wall 120, and interference with other structures is avoided. Optionally, the shape of the mounting plate 220 can be any shape, such as a square or a circle, which is not limited in the application.

[0072] As an optional solution, the oil pan assembly 1000 further includes a sealing assembly 300, the oil pan body 100 has a second wall 130 for defining another side of the oil cavity 110, and the sealing assembly 300 is used to seal the connecting assembly 200 and the first side wall 120, the connecting assembly 200 and the oil outlet pipe 2000, and the connecting assembly 200 and the second wall 130, so as to improve the sealing between the connecting assembly 200 and the oil pan assembly 1000 and the oil outlet pipe 2000, and to facilitate maintaining the oil pressure of the oil pump.

[0073] Specifically, the sealing assembly 300 includes a first seal 310 located between the mounting plate 220 and the first sidewall 120 to improve the sealing performance between the mounting plate 220 and the first sidewall 120.

[0074] The sealing assembly 300 also includes a second seal 320, which is located between the oil pump outlet pipe 2000 and the connecting pipe 210 to ensure a sealing effect between the oil pump outlet pipe 2000 and the connecting pipe 210. Specifically, the oil pump outlet pipe 2000 defines a first receiving groove 2002, which is located on the outer wall of the oil pump outlet pipe 2000. The second seal 320 is sleeved on the oil pump outlet pipe 2000 and located in the first receiving groove 2002. When the oil pump outlet pipe 2000 is inserted into the connecting pipe 210, the second seal 320 abuts against the inner wall of the connecting pipe 210, thereby achieving a seal between the oil pump outlet pipe 2000 and the connecting pipe 210.

[0075] The sealing assembly 300 also includes a third seal 330, which is located between the connecting pipe 210 and the second wall 130 to ensure a tight seal between them. Specifically, the connecting pipe 210 defines a second receiving groove 215 located on its outer wall. The third seal 330 is fitted onto the connecting pipe 210 and located within the second receiving groove 215. When the connecting pipe 210 passes through the second wall 130 and connects to the oil pump outlet pipe 2000, the third seal 330 abuts against the second wall 130, sealing the oil chamber 110 and preventing oil from overflowing from the gap between the second wall 130 and the connecting pipe 210.

[0076] Now combined Figures 1-6 The working process of the oil pan assembly 1000 is explained.

[0077] like Figures 1-6 As shown, when the operator needs to disassemble the oil pan body 100, simply remove the fastener 230 that fixes the first side wall 120 and the mounting plate 220, so that the mounting plate is detached from the first side wall, and then pull out the connecting component 200. At this time, the oil pump outlet pipe 2000 can be separated from the oil pan body 100, and then the operator can remove or replace the oil pan body 100.
