Oil sump of automobile engine
Technical Field
The utility model belongs to the automobile field especially relates to automobile engine, specifically speaking are automobile engine oil drain pan.
Background
The oil sump of the vehicle engine is used for sealing the crankcase as a shell of the oil storage tank to prevent external impurities from entering, collecting and storing lubricating oil flowing back from each friction surface of the internal combustion engine, dissipating part of heat and preventing the lubricating oil from being oxidized. The bottom of the existing oil pan is mostly designed in a plane, which is not beneficial to the flow of lubricating oil and has high residual oil rate when the lubricating oil is replaced; the oil sump is internally provided with no independent lubricating oil stabilizing chamber structure, and only an oil baffle structure or even no oil baffle structure is used for stabilizing lubricating oil, so that the effect of stabilizing the lubricating oil is poor; after the whole engine is assembled, the oil pan reinforcing ribs are unreasonably arranged, so that vibration of the oil pan can be caused, and noise is accompanied.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide an automobile engine oil pan, through integrating spare part functional structure, reduce and occupy the inside effective space of oil pan, have obvious damping, fall the efficiency of making an uproar to possess the undulant effect of stable lubricating oil, reduce the harm that the engine leads to because of lubricated harmfully.
In order to solve the technical problem, the utility model discloses the technical scheme who takes is:
the oil sump for automobile engine has composite inclined inner bottom formed by connecting at least three oil return inclined planes with different slopes, and the inner bottom is communicated with oil draining screw hole.
As concretization of the structure of the utility model, the composite inclined plane structure comprises a first oil return inclined plane, a second oil return inclined plane and a third oil return inclined plane which are connected into a whole; wherein,
the fourth oil return inclined surface and the fifth oil return inclined surface are connected to form a bottom layer of the oil pan, and the joint between the fourth oil return inclined surface and the fifth oil return inclined surface, namely the junction, is an extremely low part of the oil pan and is communicated with the oil drain plug hole;
the first oil return inclined surface and the second oil return inclined surface are connected to form an upper layer of the oil pan;
the third oil return inclined plane is connected between the upper layer and the lower layer of the oil pan and is connected into a whole, and the slope of the third oil return inclined plane is the largest among the first oil return inclined plane, the second oil return inclined plane and the fifth oil return inclined plane.
As the utility model discloses a further inject, the fixed boss of oil pan inside, oil baffle and lubricating oil collector department is connected with the strengthening rib.
(because the fixed boss of oil baffle plate links firmly with oil pan bottom surface and casing lateral wall, the fixed boss of machine oil collector links firmly with oil pan bottom surface, with the two and strengthening rib even as an organic whole increased the area that links firmly of strengthening rib and oil pan, strengthened the overall structure intensity of oil pan, reduced the vibration and the noise of oil pan when the complete machine moves
And reinforcing ribs are respectively connected to the fixing boss of the oil baffle on the fourth oil return slope and the fixing boss of the engine oil collector, and a lubricating oil stabilizing chamber is arranged between the reinforcing ribs and the third oil return slope.
(the oil stabilizing chamber can effectively reduce the fluctuation of engine oil and the phenomenon of oil surface shock and splash bubbles caused by bumping, the effect of stabilizing the fluctuation of lubricating oil is better, and meanwhile, the oil stabilizing chamber is beneficial to the precipitation of impurities in the lubricating oil.)
Owing to adopted foretell technical scheme, compared with the prior art, the utility model, the technological progress who gains lies in: the utility model combines the oil baffle plate fixing boss of the oil pan, the lubricating oil collector fixing boss and the reinforcing rib into a lubricating oil stabilizing chamber structure, has the function of stabilizing the fluctuation of lubricating oil, reduces the harm of the engine caused by poor lubrication, and has obvious vibration and noise reduction effects; the structure that the fixed boss of oil pan oil baffle and the fixed boss of lubricating oil collector and strengthening rib combined together increases the inside effective volume of oil pan, and then alleviates oil pan overall quality, and with oil pan oil baffle combined action, can further strengthen the effect that lubricating oil was stabilized to the oil pan.
The utility model discloses be suitable for the oil pan of various cars.
The present invention will be described in further detail with reference to the drawings and specific embodiments.

Detailed Description
Example 1
Fig. 1-3 show an oil pan of an automobile engine, which is an aluminum double-layer structure.
Firstly, the oil pan structure is different from the existing oil pan structure in that:
the inner bottom of the oil bottom shell main body is of a composite inclined plane structure, namely, the oil bottom shell main body is formed by connecting at least three oil return inclined planes with different slopes, and the inner bottom is communicated with the oil drain plug hole.
The inclined plane structure is communicated with the oil drain plug hole. Specifically, the following are:
the inclined plane structure comprises first to fifth oil return inclined planes 11 to 15 which are connected into a whole.
The fourth oil return inclined surface 14 and the fifth oil return inclined surface 15 are connected to form a bottom layer of the oil pan, and a joint 7 between the fourth oil return inclined surface and the fifth oil return inclined surface, namely a junction, is an extremely low position of the oil pan and is communicated with the oil drain plug hole.
The first oil return inclined surface 11 and the second oil return inclined surface 12 are connected to form an upper layer of the oil pan.
The third oil return inclined surface 13 is connected between the upper layer and the lower layer of the oil pan, the third oil return inclined surface 13, the upper layer and the lower layer are connected into a whole, and the slope of the third oil return inclined surface 13 is the largest among the first oil return inclined surface 11 to the fifth oil return inclined surface 15.
The inner part of the oil pan and part of the oil pan mounting hole are connected with reinforcing ribs 4 at the fixed boss 3 of the oil baffle plate and the fixed boss 2 of the lubricating oil collector. Reinforcing ribs 41 and 42 are connected to the fixing boss of the oil baffle on the fourth oil return slope and the fixing boss of the engine oil collector, and a lubricating oil stabilizing chamber 5 is arranged between the reinforcing ribs 41 and 42 and the third oil return slope 13.
Secondly, the structure of other parts of the present embodiment is the same as the prior art.
