Description
Technical Field
[0001] The utility model relates to the field of automobile accessories, in particular to an oil pan, an engine and a vehicle. Background Art
[0002] The oil pan is a component of the engine lubrication system. It is a shell that seals the crankshaft oil pan and serves as an oil storage tank. Among them, plastic oil pans are mostly used in road commercial vehicles, while non-road vehicles with harsh working environments require metal oil pans to improve durability. However, the metal oil pans used in non-road applications usually have a large capacity and a large oil weight, requiring the oil pan to have high-strength working performance. At the same time, the volume of the non-road oil pan is also large, and the internal oil has enough space to slosh, which has a greater impact on the oil pan.
[0003] The traditional engine oil pan includes a large end with a deep groove area and a small end with a shallow groove area. There is a distance between the bottom end of the deep groove area of the conventional oil pan and the standard tooling pallet and will not touch the standard tooling pallet. However, due to the large capacity of the metal oil pan and the heavy weight of the oil body, the depth of the deep groove area needs to be increased, resulting in contact between the bottom of the oil pan and the standard tooling pallet, causing the columns on the standard tooling pallet to interfere with the production of the oil pan, which makes it impossible to adapt to the standard tooling pallet in the factory production line. Only non-standard tooling can be newly produced, resulting in high design and manufacturing costs.
[0004] Therefore, it is urgent to propose corresponding solutions to the problem that the oil pan with a large oil storage capacity contacts the standard tooling pallet, and because the oil pan and the standard tooling pallet cannot be adapted to each other due to interference from the columns on the tooling pallet, new non-standard tooling needs to be developed, which leads to high design and manufacturing costs. Utility Model Content
[0005] The purpose of the utility model is to overcome the problem in the prior art that an oil pan with a large oil storage capacity contacts with a standard tooling pallet, and due to interference from columns on the tooling pallet, the oil pan and the standard tooling pallet cannot be adapted to each other, and a new non-standard tooling needs to be developed, resulting in high design and manufacturing costs.
[0006] In order to achieve the above-mentioned objectives, the utility model provides, on the one hand, an oil pan, including an oil pan body with a cavity formed inside, the oil pan body including a deep oil storage area and a shallow oil storage area connected to each other, and the bottom surface of the deep oil storage area is formed with a protrusion protruding from bottom to top for adapting to a column on a tooling pallet.
[0007] In some embodiments, the raised portion includes a first bump and a second bump which are arranged on the bottom surface of the deep oil storage area and are spaced apart along the width direction, and the positions of the first bump and the second bump are opposite to each other in relation to the column.

[0013] In some embodiments, the oil pan further includes an oil drain hole, and the oil drain hole is arranged at the bottom of the side wall of the deep oil storage area.
[0014] A second aspect of the utility model provides an engine, comprising the above-mentioned oil pan.

It should also be understood that terms defined in general dictionaries, for example, should be interpreted as having meanings consistent with their meanings in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined as such herein.
[0032] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.
[0033] In order to overcome the problem in the prior art that the oil pan with a large oil storage capacity contacts the standard tooling pallet, the oil pan and the standard tooling pallet cannot be adapted due to the interference of the columns on the tooling pallet, and a new non-standard tooling needs to be developed, resulting in high design and manufacturing costs. Figure 1 and Figure 2 As shown, on one hand, the utility model provides an oil pan, including an oil pan body with a cavity formed inside, the oil pan body including a deep oil storage area 1 and a shallow oil storage area 2 connected to each other, and a protrusion 3 is formed on the bottom surface of the deep oil storage area 1 and protrudes from bottom to top for matching with a column on a tooling pallet.
[0034] Specifically, combined Figure 1 and Figure 2As shown, since the level of the lubricating oil in the oil pan directly affects the performance of the engine, too low a lubricating oil level is not conducive to the lubrication of the engine components, especially for vehicles traveling on unconventional roads, the oil pan has a large capacity and a large oil weight, and the oil pan needs to have high-strength working performance. Therefore, in order to be able to make the depth of the lubricating oil reach an ideal state under the condition of a certain lubricating oil, it is beneficial to the operation of the engine. The oil pan body needs to be provided with a deep oil storage area 1 and a shallow oil storage area 2, and a protruding portion 3 protruding from bottom to top is provided on the bottom surface of the deep oil storage area 1 of the oil pan body, and the protruding portion 3 is adapted to the column on the tooling pallet. When the bottom of the oil pan contacts the tooling pallet, the setting of the protruding portion 3 can avoid the interference of the column on the tooling pallet with the production of the oil pan, so that the oil pan and the tooling pallet can be adapted, and there is no need to develop and set a new pallet mold, which reduces the design cost and manufacturing cost.
[0035] In some embodiments, in combination Figure 1 As shown, the raised portion 3 includes a first convex block 31 and a second convex block 32 which are arranged on the bottom surface of the deep oil storage area 1 and spaced apart in the width direction. The positions of the first convex block 31 and the second convex block 32 are opposite to the column.
[0036] Specifically, combined Figure 1 and Figure 2 As shown, there is a gap between the first protrusion 31 and the second protrusion 32 arranged along the width direction of the bottom surface of the deep oil storage area 1, and they are not raised upward as a whole, and the positions of the first protrusion 31 and the second protrusion 32 are opposite to each other with the pillar, so as to accurately avoid the pillar and avoid interference caused by the pillar. In addition, when the vehicle travels to an uneven road section, the protrusion 3 can block the vibration and impact of the oil in the oil pan, play a blocking role, and avoid the oil pan from being damaged due to long-term vibration and impact.
[0037] In some embodiments, in combination Figure 2 As shown, the raised portion 3 may be in an arc shape, and the raised portion 3 protrudes upward from the bottom surface of the deep oil storage area 1 to avoid the columns on the standard tooling pallet, thereby preventing the columns from interfering with the production of the oil pan.
[0038] Wherein, in some embodiments, reference Figure 1 and Figure 2 As shown, it also includes reinforcing ribs respectively arranged inside the deep oil storage area 1 and the shallow oil storage area 2, and the reinforcing ribs include a plurality of first reinforcing ribs 41 arranged on the side wall of the deep oil storage area 1 and extending vertically, and a plurality of second reinforcing ribs 42 arranged on the bottom surface of the shallow oil storage area 2 and extending along the length direction.
[0039] Specifically, by providing reinforcing ribs inside the deep oil storage area 1 and the shallow oil storage area 2, not only the overall rigidity of the oil pan is increased, the oil pan is prevented from being deformed due to the impact of the oil, but also the impact resistance of the oil pan is enhanced. When the vehicle is driving on uneven roads, the reinforcing ribs can to a certain extent block the flow of lubricating oil and impact on the side wall of the oil pan, thereby reducing the impact force of the oil.
[0040] Furthermore, combined with Figure 1 and Figure 2 As shown, a plurality of first reinforcing ribs 41 can be evenly spaced along the side wall of the deep oil storage area 1, and a plurality of second reinforcing ribs 42 can be evenly spaced along the width direction of the bottom surface of the shallow oil storage area 2. Such an arrangement can further improve the overall rigidity and strength of the oil pan, play a buffering role for the vibrating engine oil, and effectively avoid deformation of the oil pan due to vibration.
[0041] Wherein, in some embodiments, reference Figure 2 As shown, it also includes an assembly surface 5 arranged on the top of the oil pan body, and the assembly surface 5 includes a first assembly surface 51 arranged on the top of the deep oil storage area 1 and a second assembly surface 52 arranged on the top of the shallow oil storage area 2. The first assembly surface 51 and the second assembly surface 52 are in the same plane.
[0042] Specifically, combined Figure 1 and Figure 2 As shown, the first assembly surface 51 at the top of the deep oil storage area 1 and the second assembly surface 52 at the top of the shallow oil storage area 2 are in the same plane, that is, the tops of the deep oil storage area 1 and the shallow oil storage area 2 are flush and can be connected to the engine cylinder block (not shown in the figure).
[0043] Wherein, in some embodiments, Figure 2 As shown, the bottom surface of the deep oil storage area 1 and the bottom surface of the shallow oil storage area 2 are transitionally connected by an arc surface 6. Such an arrangement can make the lubricating oil between the shallow oil storage area 2 and the deep oil storage area 1 smoothly transition, effectively preventing the accumulation of oil dirt.
[0044] Wherein, in some embodiments, Figure 2 As shown, the oil pan further comprises an oil drain hole 7 , which is arranged at the bottom of the side wall of the deep oil storage area 1 .
[0045] Specifically, the lubricating oil in the oil pan can be discharged through the oil drain hole 7 without disassembling the oil pan, so as to replace the new lubricating oil. The oil drain hole 7 can be arranged at the bottom of the side wall of the deep oil storage area 1. When the vehicle is driving on a bad road environment, the oil pan is easy to vibrate and touch the bottom. Therefore, the oil drain hole 7 arranged on the side wall of the oil pan can avoid contact with the bottom and cause the hole to loosen, thereby avoiding leakage of the lubricating oil in the oil pan.
[0046] The second aspect of the utility model provides an engine, comprising the above-mentioned oil pan, wherein the oil pan can be connected to an engine cylinder block, and the engine cylinder block is arranged above the oil pan.
[0047] The third aspect of the utility model provides a vehicle, comprising the above-mentioned engine, wherein both the engine and the vehicle have the above-mentioned oil pan.
