[0046] The embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation of the present utility model.

[0047] Next, with reference to the drawings, the pump assembly 1 of a vehicle according to an embodiment of the present utility model will be described.

[0048] As Figures 1 - 8As shown, the pump assembly 1 of a vehicle according to an embodiment of the present utility model includes: a return oil pump 11, the return oil pump 11 includes a first oil chamber 111, a first oil inlet 112 and a second oil inlet 113 are correspondingly provided for the first oil chamber 111, and the first oil inlet 112 and the second oil inlet 113 are distributed on different side walls of the return oil pump 11.

[0049] Thus, a certain distance can be maintained between the first oil inlet 112 and the second oil inlet 113, which is beneficial to preventing leakage, reducing the processing difficulty and processing cost, and can also reduce the installation difficulty of the pump assembly 1, improving the practicability of the pump assembly 1.

[0050] First, as Figures 1 - 6 shown, the pump assembly 1 includes a return oil pump 11, a first oil chamber 111 is formed in the return oil pump 11, the return oil pump 11 is provided with a first oil inlet 112 and a second oil inlet 113, the first oil inlet 112 and the second oil inlet 113 are respectively communicated with the first oil chamber 111, the first oil inlet 112 and the second oil inlet 113 are used for communicating with a return oil component (such as a master cylinder block 2 and an oil pan 3), and the first oil chamber 111 can be communicated with the following oil storage device (such as an oil pot).

[0051] The return oil pump 11 further includes a first rotating member 14 and a second rotating member 15. The first rotating member 14 is rotatably installed in the first oil chamber 111. When the first rotating member 14 rotates in the forward direction, the oil outlet 114 is located downstream of the first oil inlet 112, and the first rotating member 14 can guide the oil from the first oil inlet 112 to the oil outlet 114; the second rotating member 15 is rotatably installed in the first oil chamber 111. When the second rotating member 15 rotates in the reverse direction, the oil outlet 114 is located downstream of the second oil inlet 113, and the second rotating member 15 can guide the oil from the second oil inlet 113 to the oil outlet 114. In this way, the return oil pump 11 can return oil from the first oil inlet 112 and the second oil inlet 113 respectively, and the oil flowing into the first oil chamber 111 can flow out to the oil storage device intensively.

[0052] It should be noted that the first rotating member 14 and the second rotating member 15 can be any one of a gear, a ratchet or a screw. In addition, the first rotating member 14 can be set to rotate clockwise, and the second rotating member 15 can be set to rotate counterclockwise.

[0053] Among them, the first oil inlet 112 and the second oil inlet 113 can be distributed on different side walls of the return oil pump 11, such as Figure 2 shown on the left and right side walls. Thus, a certain distance can be maintained between the first oil inlet 112 and the second oil inlet 113, leakage can be prevented, the processing difficulty and processing cost can be reduced, and the first oil inlet 112 and the second oil inlet 113 are more easily connected to the oil return position, which is beneficial to reducing the installation difficulty of the pump assembly 1.

[0054] In addition, the first oil inlet 112 and the second oil inlet 113 are relatively independent. When one of the first oil inlet 112 and the second oil inlet 113 is sucked empty, the other can suck oil normally, which helps to reduce the risk of abnormal wear and abnormal noise.

[0055] For the pump assembly 1 of the vehicle according to the embodiment of the present invention, by respectively arranging the first oil inlet 112 and the second oil inlet 113 on the opposite side walls of the oil return pump 11, a certain distance can be maintained between the first oil inlet 112 and the second oil inlet 113, which helps to prevent leakage, reduces the processing difficulty and processing cost, and can also reduce the installation difficulty of the pump assembly 1, improving the practicability of the pump assembly 1.

[0056] In some embodiments of the present invention, the pump assembly 1 includes a plurality of oil return pumps 11. The plurality of oil return pumps 11 are arranged along the first direction L1, and the pump bodies of the plurality of oil return pumps 11 are fixedly connected to form a pump main body 13. In the second direction L2, the first oil inlet 112 and the second oil inlet 113 are located on the opposite side walls of the pump main body 13, and the first direction L1 and the second direction L2 are perpendicular to each other.

[0057] For example, with reference to Figures 1 - 4 shown, the first direction L1 and the second direction L2 are perpendicular to each other. For example, the first direction L1 can be set as Figure 3 the front-back direction shown, and the second direction L2 can be set as Figure 1 the left-right direction shown. The pump assembly 1 includes a plurality of oil return pumps 11. The plurality of oil return pumps 11 are arranged along the first direction L1, the pump bodies of the plurality of oil return pumps 11 are fixedly connected to form a pump main body 13, and in the second direction L2, the first oil inlet 112 and the second oil inlet 113 of each oil return pump 11 are respectively located on the opposite side walls of the pump main body 13.

[0058] Through the above settings, the end face space can be fully utilized to arrange the first oil inlet 112 and the second oil inlet 113, improving the integration degree, simplifying the structure of the pump assembly 1, facilitating the installation and layout of the pump assembly 1, and being conducive to subsequent maintenance.

[0059] In some embodiments of the present invention, as Figure 1 shown, the second direction L2 can be set as the horizontal direction. The two side walls of the oil return pump 11 in the second direction L2 are respectively the first side wall 132 and the second side wall 133. The first oil inlet 112 is located on the first side wall 132, and the second oil inlet 113 is located on the second side wall 133. The first side wall 132 and the second side wall 133 are parallel and perpendicular to the top wall 131 of the pump main body 13. It should be noted that the horizontal direction refers to the horizontal plane of the engine 100 when the vehicle is driving on a flat road surface.

[0060] Through the above settings, the pump body 13 can be easily positioned for machining, the complexity of the fixture can be reduced, and the machining efficiency can be improved.

[0061] In some embodiments of the present utility model, the oil return pump 11 is provided with an oil outlet 114 corresponding to the first oil chamber 111, the pump body 13 is provided with a total oil outlet 134, the oil outlets 114 of multiple oil return pumps 11 are respectively communicated with the total oil outlet 134, and the total oil outlet 134 is adapted to be communicated with an oil storage device.

[0062] For example, as shown in Figures 1 - 4 The oil return pump 11 is provided with an oil outlet 114 corresponding to the first oil chamber 111, and the oil outlet 114 is located between the first oil inlet 112 and the second oil inlet 113. At the same time, a total oil outlet 134 can be provided on the side wall of the pump body 13 along the second direction L2, the oil outlets 114 of multiple oil return pumps 11 are respectively communicated with the total oil outlet 134, and the total oil outlet 134 is adapted to be communicated with an oil storage device, so that the oil collected by multiple oil return pumps 11 can flow into the oil storage device through the total oil outlet 134. Thereby, the structure of the pump assembly 1 can be simplified, the pump assembly 1 and the oil storage device can be more easily communicated, and the practicability of the pump assembly 1 is improved.

[0063] In some embodiments of the present utility model, the diameter of the total oil outlet 134 can be set to be larger than the diameters of the first oil inlet 112 and the second oil inlet 113. Through the above settings, the risk of throttling and air suction can be reduced, the oil loss can be reduced, the oil return efficiency of the oil return pump 11 can be improved, and the occurrence of abnormal noise and cavitation can be avoided.

[0064] In some embodiments of the present utility model, as shown in Figure 4 The diameter of the total oil outlet 134 can be set to d1, and the diameter of the first oil inlet 112 can be set to d2, satisfying: 1.5d2 ≤ d1 ≤ 3d2. That is to say, the diameter d1 of the oil outlet 114 can be set to be greater than or equal to 1.5 times the diameter d2 of the first oil inlet 112 and less than or equal to 3 times the diameter d2 of the first oil inlet 112, such as 1.5d2, 1.6d2, 2d2, 2.5d2, 2.9d2, 3d2, etc., and the present utility model does not limit this. Thereby, the oil return efficiency of the oil return pump 11 can be better guaranteed, and the occurrence of abnormal noise and cavitation can be avoided.

[0065] In some embodiments of the present utility model, as shown in Figure 3As shown, the diameter of the total oil outlet 134 can be set as d1, and the diameter of the second oil inlet 113 can be set as d3, satisfying: 1.5d3 ≤ d1 ≤ 3d3. That is to say, the diameter d1 of the oil outlet 114 can be set to be greater than or equal to 1.5 times the diameter d3 of the second oil inlet 113 and less than or equal to 3 times the diameter d3 of the second oil inlet 113, such as 1.5d3, 1.6d3, 2d3, 2.5d3, 2.9d3, 3d2, etc., and the present utility model does not limit this. Thus, the oil return efficiency of the oil return pump 11 can be better ensured, and the occurrence of abnormal noise and cavitation can be avoided.

[0066] In some embodiments of the present utility model, as Figures 3 - 4 shown, the pump assembly 1 of the vehicle in the embodiment of the present utility model further includes an oil supply pump 12. The oil supply pump 12 has an oil supply inlet 121 and an oil supply outlet 122. The oil supply inlet 121 is communicated with an oil storage device so that the oil in the oil storage device can flow into the oil supply pump 12 through the oil supply inlet 121. The oil supply outlet 122 is communicated with the parts in the engine 100 that need to be lubricated (such as the crankshaft surface, intake VVT, exhaust VVT, etc.). The oil flowing into the oil supply pump 12 can flow to this part through the oil supply outlet 122 for lubrication. Among them, the oil supply inlet 121 and the oil supply outlet 122 can be set to be located on different side walls of the oil supply pump 12 respectively.

[0067] Through the above settings, a certain distance can be maintained between the oil supply inlet 121 and the oil supply outlet 122, which is beneficial to preventing leakage, reducing the processing difficulty and processing cost, and making it easier for the oil supply inlet 121 and the oil supply outlet 122 to be communicated with the corresponding parts, which is beneficial to reducing the installation difficulty of the pump assembly 1.

[0068] In some embodiments of the present utility model, as Figure 3 shown, the oil supply pump 12 and the oil return pump 11 are fixedly connected. The oil supply inlet 121 and one of the first oil inlet 112 and the second oil inlet 113 are located on the same side, and the oil supply outlet 122 and the other of the first oil inlet 112 and the second oil inlet 113 are located on the same side.

[0069] Through the above settings, it is convenient to arrange the oil circuit interfaces corresponding to the pump assembly 1 on the corresponding parts of the engine 100 (such as the cylinder block, timing cover, oil pan 3, etc.), simplifies the structure, reduces the flow resistance, improves the pressure response time, and at the same time can make full use of the lateral space of the pump assembly 1, reduces the vertical height dimension of the engine 100, reduces the center of gravity, and is beneficial to the layout of the engine 100 in the whole vehicle.

[0070] In some embodiments of the present utility model, the diameter of the oil supply inlet 121 can be set to be larger than the diameter of the oil supply outlet 122. Through the above setting, the throttling and air suction risks can be reduced, the oil loss can be minimized, the oil supply efficiency of the oil supply pump 12 can be improved, and the occurrence of abnormal noise and cavitation can be avoided.

[0071] In some embodiments of the present utility model, the diameter of the oil supply inlet 121 is d4, and the diameter of the oil supply outlet 122 is d5, satisfying: 1.2d5 ≤ d4 ≤ 2d5. That is to say, the diameter d4 of the oil supply inlet 121 can be set to be greater than or equal to 1.2 times the diameter d5 of the oil supply outlet 122 and less than or equal to 2 times the diameter d5 of the oil supply outlet 122, such as 1.2d5, 1.4d5, 1.6d5, 1.8d5, 2d5, etc., and the present utility model does not limit this. Thus, the oil return efficiency of the oil supply pump 12 can be better ensured, and the occurrence of abnormal noise and cavitation can be avoided.

[0072] In some embodiments of the present utility model, the pump assembly 1 of the vehicle in the embodiments of the present utility model further includes a guide oil pipe 16. The different side walls of the oil return pump 11 are respectively provided with the guide oil pipe 16, and the guide oil pipe 16 is used to communicate with the first oil inlet 112 or the second oil inlet 113.

[0073] For example, referring to Figure 5 As shown, the pump assembly 1 further includes a guide oil pipe 16. There are a plurality of guide oil pipes 16, and the plurality of guide oil pipes 16 are respectively connected to the opposite sides of the oil return pump 11 along the second direction L2 (i.e., the opposite sides of the pump body 13 along the second direction L2), and an oil passage is formed in the guide oil pipe 16 for guiding the oil.

[0074] Specifically, the guide oil pipe 16 on the same side as the first oil inlet 112 can connect the first oil inlet 112 and the corresponding oil return component; the guide oil pipe 16 on the same side as the second oil inlet 113 can connect the second oil inlet 113 and the corresponding oil return component.

[0075] Of course, the present utility model is not limited thereto. The guide oil pipe 16 on the same side as the total oil outlet 134 can connect the total oil outlet 134 and the oil storage device; the guide oil pipe 16 on the same side as the oil supply inlet 121 can connect the oil supply inlet 121 and the oil storage device; the guide oil pipe 16 on the same side as the oil supply outlet 122 can connect the oil supply outlet 122 with the part that needs lubrication.

[0076] Through the above setting, the pump assembly 1 can be stably connected to the corresponding components of the engine 100, and the oil circuit structure can be simplified, the length and bend angle of the guide oil pipe 16 can be reduced, the flow resistance can be lowered, and the pressure response time can be improved.

[0077] In some embodiments of the present utility model, such as Figures 3 - 4As shown, an annular sealing groove 135 is provided on the side wall of the oil return pump 11 corresponding to each oil guide pipe 16. A sealing member is provided in the sealing groove 135. The sealing member can be made of elastic materials such as foam and rubber. When the oil guide pipe 16 is supported and connected to the side wall of the pump body 13, the sealing member can be in sealing fit with the end of the oil guide pipe 16 in the circumferential direction.

[0078] For example, when the oil guide pipe 16 is used to communicate with the first oil inlet 112, the corresponding sealing groove 135 is arranged around the first oil inlet 112. Thus, the sealing performance of the oil guide pipe 16 can be improved, and the reliability of the pump assembly 1 is improved.

[0079] Of course, the present invention is not limited thereto. When the oil guide pipe 16 is used to communicate with the oil supply inlet 121, an annular sealing groove 135 can be provided on the side wall of the oil supply pump 12, and the corresponding sealing groove 135 is arranged around the oil supply inlet 121; and so on, which will not be elaborated herein.

[0080] In some embodiments of the present invention, as Figures 3 - 4 shown, at least one mounting hole 136 can be provided on the side wall of the oil return pump 11 corresponding to each oil guide pipe 16. An outwardly protruding mounting protrusion 161 is provided on the circumference of the oil guide pipe 16. The mounting protrusion 161 has a mounting through hole penetrating in the thickness direction. The fastener 4 is inserted through the mounting through hole and connected to the mounting hole 136 to mount the oil guide pipe 16 on the pump body 13.

[0081] Exemplarily, two mounting holes 136 can be provided on the side wall of the oil return pump 11 corresponding to each oil guide pipe 16. The two mounting holes 136 corresponding to the same oil guide pipe 16 are symmetrically arranged with respect to the oil guide pipe 16; or, multiple mounting holes 136 can be provided on the side wall of the oil return pump 11 corresponding to each oil guide pipe 16, and the multiple mounting holes 136 are arranged at intervals in the circumferential direction of the oil guide pipe 16.

[0082] Of course, the present invention is not limited thereto. When the oil guide pipe 16 is used to communicate with the oil supply pump 12, mounting holes 136 can be provided on the side wall of the oil supply pump 12 corresponding to each oil guide pipe 16; and so on, which will not be elaborated herein.

[0083] Through the above settings, the structure of the pump assembly 1 can be simplified, and the sealed connection between the pump body 13 and the oil guide pipe 16 can be made reliable, which is beneficial to reducing costs and improving the practicability of the pump assembly 1.

[0084] In some embodiments of the present invention, filters can be installed at the first oil inlet 112 and the second oil inlet 113. The filters can be fixed by interference fit or riveting. The filters filter the oil entering the oil return pump 11. Thus, problems such as jamming and wear caused by impurities entering the oil return pump 11 can be avoided.

[0085] The present utility model also provides an engine 100.

Moreover, the oil pan 3 can be used to temporarily collect and store the lubricating oil flowing back from the parts in the main cylinder block 2 that need lubrication (such as the surface of the crankshaft, intake VVT, exhaust VVT, etc.), so as to realize the recycling of the lubricating oil.

[0088] The engine 100 further includes a pump assembly 1 and an oil storage device. The pump assembly 1 is installed in the oil pan 3. The pump assembly 1 includes a scavenge pump 11. There are multiple scavenge pumps 11. The multiple scavenge pumps 11 are respectively communicated with the oil storage device through an oil outlet 114.
