Vehicles have become indispensable vehicles in people's lives, and engines are very important components of vehicles and are used for providing power for the vehicles.

The engine oil baffle is an important part in an engine lubricating system, is generally arranged between a crankcase and an oil pan, and has the main function of preventing engine oil in the oil pan from shaking at a large liquid level.

In the related art, the oil separator is fixed to the lower portion of the crankcase by bolts. However, when the oil separator is fixed by bolts, the bolt torque may not be in place during the actual assembly process, or the oil separator may be crushed due to too large bolt torque, which is time-consuming and labor-consuming in operation.

In order to solve the problems in the related art, an embodiment of the present application provides an oil baffle, which is schematically shown in fig. 1.

Referring to fig. 1, the engine oil baffle comprises an arc-shaped surface 1, and a first mounting surface 2 and a second mounting surface 3 which are positioned at two opposite sides of the arc-shaped surface 1;

a first side of the first mounting surface 2 is provided with a plurality of guiding elements 4, and the guiding elements 4 protrude in a direction away from the first mounting surface 2;

a plurality of positioning pieces 5 are arranged on the second side of the second mounting surface 3, the positioning pieces 5 are arc-shaped, one side of each positioning piece 5 is connected with the second mounting surface 3, and the other side of each positioning piece 5 is separated from the second mounting surface 3 by a preset distance;

the first mounting surface 2 and the second mounting surface 3 are positioned on the same plane, the first side and the second side are positioned on the same side of the plane, and the arc-shaped surface 1 is positioned on the other side of the plane.

Therefore, the engine oil baffle provided by the embodiment of the application realizes the positioning and the primary fixing of the engine oil baffle through the guide parts 4 and the positioning parts 5 on the engine oil baffle, when in use, the guide parts 4 positioned on the first side of the first mounting surface 2 can be inserted into the guide part grooves positioned on the crankcase 14 in a one-to-one correspondence manner, and then the positioning parts 5 positioned on the second side of the second mounting surface 3 can be buckled in the positioning grooves on the crankcase 14 in a one-to-one correspondence manner, so that the fixed connection between the engine oil baffle and the crankcase 14 is realized. Compared with the mode of fixing through bolts in the related art, the connecting mode is simple to operate, and the working efficiency of operators is improved.

In addition, the engine oil baffle plate provided by the embodiment of the application is not required to be fixed by bolts, so that a metal insert sleeve for meeting bolt installation torque is not required to be injected, and the preparation method is simpler.

The following describes the mutual positions and connection relationships among the parts of the oil separator, and the functions and operating principles of the parts, etc. provided by the embodiments of the present application:

in some embodiments, referring to fig. 2, the guide 4 is a protrusion having a cross-sectional area that gradually decreases in a direction away from the first mounting surface 2.

This is provided to facilitate insertion of the guide 4 into the guide groove on the crankcase 14.

In some embodiments, the protrusions may be cone-type protrusions or truncated cone-type protrusions.

In some embodiments, the side of the protrusion away from the first mounting surface 2 may be a point, a line segment, a curve segment, a plane, a curved surface, or the like. For example, referring to fig. 2, the side of the projection remote from the first mounting surface 2 is a flat surface.

In some embodiments, when the side of the protrusion away from the first mounting surface 2 is a plane, the plane may be parallel to the first mounting surface 2, or may form a predetermined angle with the first mounting surface 2.

In some embodiments, the shape of the cross section of the protrusion may be circular, oval, trapezoidal, triangular, square, rectangular, pentagonal, etc., and is not particularly limited herein.

In some embodiments, the height of the protrusions ranges from 0.3cm to 3 cm. For example, the height of the protrusions may be 0.3cm, 0.4cm, 1.0cm, 2.0cm, 3.0 cm.

In some embodiments, the material of the guide member 4 includes, but is not limited to, polyethylene, polypropylene, polyvinyl chloride, acrylonitrile butadiene styrene, polystyrene, and the like.

In some embodiments, referring to fig. 2, the protrusion comprises a cylinder having a slope on a side of the protrusion facing the second mounting surface 3, the slope gradually increasing in height in a direction away from the second mounting surface 3.

So arranged, the insertion of the guide 4 into the guide slot is facilitated.

In some embodiments, the material of the arc-shaped face 1 includes, but is not limited to, polyethylene, polypropylene, polyvinyl chloride, acrylonitrile-butadiene-styrene, polystyrene, and the like. For example, the material of the arc-shaped face 1 is polyethylene.

In some embodiments, the material of the first mounting surface 2 includes, but is not limited to, polyethylene, polypropylene, polyvinyl chloride, acrylonitrile butadiene styrene, polystyrene, and the like. For example, the material of the first mounting surface 2 is polyethylene.

In some embodiments, the material of the second mounting surface 3 includes, but is not limited to, polyethylene, polypropylene, polyvinyl chloride, acrylonitrile butadiene styrene, polystyrene, and the like. For example, the material of the second mounting surface 3 is polyethylene.

In some embodiments, the material of the guide 4 includes, but is not limited to, polyethylene, polypropylene, polyvinyl chloride, acrylonitrile butadiene styrene, polystyrene, and the like. For example, the material of the guide 4 is polyethylene.

In some embodiments, the material of the spacer 5 includes, but is not limited to, polyethylene, polypropylene, polyvinyl chloride, acrylonitrile butadiene styrene, polystyrene, and the like. For example, the material of the positioning member 5 is polyethylene.

In some embodiments, referring to fig. 1, 2 and 4, the first mounting surface 2 has a plurality of first grooves 6 and a plurality of first protrusions 7 arranged in a one-to-one correspondence;

the first groove 6 is positioned on the first side of the first mounting surface 2, the first lug 7 is positioned on the third side of the first mounting surface 2, and the first side is opposite to the third side;

the orthographic projection of the first bump 7 on the first mounting surface 2 falls into the first groove 6, namely, the first groove 6 and the first bump 7 are correspondingly arranged on two opposite sides of the first mounting surface 2.

So set up, can further fasten the oil baffle.

It will be appreciated that the oil baffle is initially positioned and secured by the guide 4 and the locating member 5 during installation. However, the oil separator cannot be fixed firmly in the direction perpendicular to the first mounting surface 2 or the second mounting surface 3 only by virtue of the fixing of the oil separator by the guide 4 and the positioning member 5, and thus the oil separator can be fixed firmly in the direction perpendicular to the first mounting surface 2 or the second mounting surface 3 by additionally providing the first groove 6 and the first projection 7 on the oil separator. Specifically, when the oil pan 15 is mounted below the oil separator, the first protrusion 7 has a certain height, so that the first protrusion 7 can contact and press with the mounted oil pan 15, and after the first protrusion 7 is pressed by the oil pan 15, an upward acting force is generated, so that the first mounting surface 2 where the first protrusion 7 is located is moved upward by the upward acting force, i.e., moved toward the direction of the crankcase 14, and the first groove 6 provides a buffer space for the upward movement of the first mounting surface 2 where the first protrusion 7 is located, and limits the first mounting surface 2, so as to achieve further fixing in the direction perpendicular to the first mounting surface 2 or the second mounting surface 3.

It should be noted that if the first recess 6 is missing, the first mounting surface 2 on which the first projection 7 is located moves upward under the contact pressure of the oil pan 15, which may cause damage to the first mounting surface 2.

In some embodiments, the first protrusion 7 extends in a direction away from the third side of the first mounting surface 2, and the cross-sectional area of the first protrusion 7 gradually decreases in a direction away from the third side of the first mounting surface 2.

In some embodiments, the shape of the cross-section of the first bump 7 includes, but is not limited to, a triangle, a circle, a quadrangle, a pentagon, an ellipse, and the like.

In some embodiments, the height of the first bump 7 ranges from 0.3mm to 2.5 mm. For example, the height of the first bump 7 may be 0.3mm, 0.5mm, 1.0mm, 1.5mm, or 2.0 mm.

In some embodiments, the material of the first bump 7 includes, but is not limited to, polyethylene, polypropylene, polyvinyl chloride, acrylonitrile butadiene styrene, polystyrene, and the like.

In some embodiments, the shape of the cross-section of the first groove 6 includes, but is not limited to, square, rectangular, fan-shaped, triangular, or the like. For example, the first groove 6 has a rectangular cross-sectional shape.

In some embodiments, since the provision of the first groove 6 and the first protrusion 7 on the first mounting surface 2 of the oil baffle plate can only further fix the first mounting surface 2 of the oil baffle plate, which has two opposite sides, it is necessary to provide the second groove 8 and the second protrusion 9 on the second mounting surface 3 opposite to the first mounting surface 2, see fig. 1, 2 and 4, the second mounting surface 3 having a plurality of second grooves 8 and a plurality of second protrusions 9 provided in a one-to-one correspondence;

the second groove 8 is located on a second side of the second mounting surface 3, and the second protrusion 9 is located on a fourth side of the second mounting surface 3, wherein the second side is opposite to the fourth side, that is, the second groove 8 and the second protrusion 9 are located on two opposite sides of the second mounting surface 3;

the orthographic projection of the second projection 9 on the second mounting surface 3 falls into the second groove 8, i.e. the cross-sectional area of the second projection 9 is smaller than the cross-sectional area of the second groove 8.

So arranged, the working principle of the cooperation of the second groove 8 and the second projection 9 is the same as the working principle of the cooperation of the first groove 6 and the first projection 7, and specifically, when the oil pan 15 is mounted below the oil separator, since the second protrusion 9 has a certain height, the second protrusion 9 can be pressed in contact with the mounted oil pan 15, and the second projection 9 is pressed by the oil pan 15, an upward force is generated, so that the second mounting surface 3 on which the second projection 9 is arranged is moved upward by the upward force, i.e., toward the crankcase 14, the second recess 8 provides a buffer space for the upward movement of the second mounting surface 3 on which the second protrusion 9 is located, and limits the second mounting surface 3, to achieve further fixation in a direction perpendicular to the first mounting surface 2 or the second mounting surface 3. It should be noted that if the second recess 8 is missing, the second mounting surface 3 on which the second projection 9 is located moves upward under the contact pressure of the oil pan 15, possibly resulting in damage to the second mounting surface 3.

So set up, recess and arch on through crankcase 14, the oil baffle and oil pan 15's cooperation can realize that the oil baffle firmly fixes in the direction of the first installation face 2 of perpendicular to or the second installation face 3, and the installation of oil baffle need not mounting tool in this application, and simple easy operation has reduced the failure rate of installation, has saved the cost to a certain extent.

In some embodiments, the second protrusion 9 extends in a direction away from a fourth side of the second mounting surface 3.

In some embodiments, the cross-sectional area of the second bump 9 includes, but is not limited to, a triangle, a circle, a quadrangle, a pentagon, an ellipse, and the like.

In some embodiments, the height of the second bump 9 ranges from 0.3mm to 2.5 mm. For example, the height of the first bump 7 is 0.3mm, 0.5mm, 1.0mm, 1.5mm, or 2.0 mm.

In some embodiments, the material of the second bump 9 includes, but is not limited to, polyethylene, polypropylene, polyvinyl chloride, acrylonitrile butadiene styrene, polystyrene, and the like.

In some embodiments, the cross-sectional area of the second groove 8 has a shape including, but not limited to, square, rectangular, fan, triangular, and the like. For example, the cross-sectional area of the second groove 8 may be fan-shaped in shape.

In some embodiments, referring to fig. 1, the arc-shaped surface 1 has a plurality of moving rails 10, the moving rails 10 are arc-shaped, and one end of the moving rails 10 is located on the first mounting surface 2 and the other end is located on the second mounting surface 3.

Wherein the motion track 10 is used for providing a track for the motion of the connecting rod 17, that is, the connecting rod 17 moves along the motion track 10 at a position close to the arc-shaped surface 1.

It can be understood that the vehicle engine converts part of the chemical energy of combustion into mechanical work by means of the reciprocating motion of the piston 18 in the cylinder, the piston 18 is connected with one end of the connecting rod 17 through a first shaft 19a and drives the connecting rod 17 to move, and the other end of the connecting rod 17 is connected with the crankshaft 16 through a third shaft 19c and transmits the acting force of the piston 18 so as to drive the crankshaft 16 to rotate around a second shaft 19b to drive the vehicle wheels to rotate.

Further, referring to fig. 5, regarding the structure of the crankshaft 16, the crankshaft 16 includes a first portion 16a, a second portion 16b and a third portion 16c, wherein the first portion 16a is connected to one end of the second portion 16b, the other end of the second portion 16b is connected to the third portion 16c, the first portion 16a and the third portion 16c are located on the same straight line, and the second portion 16b protrudes in a direction away from the straight line where the first portion 16a and the third portion 16c are located, that is, the crankshaft 16 is a "convex" structure as a whole. The connecting rod 17 is connected to the second portion 16b of the crankshaft 16.

Referring to fig. 6, during the operation of the engine, the piston 18 of the engine reciprocates at one end far away from the oil separator, the piston 18 is connected with one end of the connecting rod 17 through the first shaft 19, the piston 18 drives the connecting rod 17 to move, the other end of the connecting rod 17 is connected with the second part 16b through the third shaft 19c, the connecting rod 17 transmits the acting force from the piston 18 and drives the crankshaft 16 to rotate around the second shaft 19b, and the reciprocating motion of the piston 18 is converted into the rotation of the crankshaft 16 through the cooperation of the connecting rod 17 and the crankshaft 16.

The piston 18 and the connecting rod 17 rotate via a first shaft 19a, the second portion 16b and the connecting rod 17 rotate via a third shaft 19c, and the crankshaft 16 rotates about a second shaft 19 b.

Wherein, the minimum distance from the arc surface 1 when the connecting rod 17 moves is smaller than the minimum distance from the arc surface 1 when the crankshaft 16 moves, therefore, the height of the moving track 10 is lower than that of the adjacent arc surface 1, so as to reserve enough space for the movement of the connecting rod 17.

In some embodiments, referring to fig. 3, the moving rail 10 has a first oil guide hole 11 and a second oil guide hole 12 in sequence along the direction from the first mounting surface 2 to the second mounting surface 3, and the first oil guide hole 11 and the second oil guide hole 12 are both located on the side of the moving rail 10 close to the second mounting surface 3, that is, the first oil guide hole 11 and the second oil guide hole 12 are sequentially located along the moving direction of the crankshaft 16 and the connecting rod 17.

It is understood that in order to reduce frictional resistance and reduce wear, the surfaces of the crankshaft 16 and the connecting rod 17 are usually coated with oil to prolong the service life thereof, and the rotation of the crankshaft 16 and the connecting rod 17 throws out the oil coated on the surfaces of the crankshaft 16 and the connecting rod 17, thereby helping to collect return oil and saving energy by providing oil guide holes in the moving direction of the crankshaft 16 and the connecting rod 17. The first oil guide hole 11 can recover the engine oil thrown out by the movement of the connecting rod 17, and the second oil guide hole 12 can recover the engine oil thrown out by the movement of the first portion 16a and the second portion 16 b.

In some embodiments, the shape of the first oil guide hole 11 includes an ellipse, a rectangle, a square, a pentagon, a rounded rectangle, and the like.

In some embodiments, the shape of the second oil guide hole 12 includes an ellipse, a rectangle, a square, a pentagon, a rounded rectangle, and the like.

With this arrangement, the oil thrown out by the movement of the connecting rod 17 and the first and second portions 16a and 16b can flow back to the oil pan 15 through the first and second oil guide holes 11 and 12, and the oil can be recovered more efficiently.

In some embodiments, referring to fig. 3, the arc-shaped surface 1 further has a plurality of third oil guide holes 13, and the third oil guide holes 13 are disposed on one side of the moving rail 10 in a one-to-one correspondence and adjacent to the second oil guide holes 12.

Wherein the third oil guide hole 13 is located in the moving direction of the third portion 16 c.

With this arrangement, the oil thrown out by the movement of the third portion 16c of the crankshaft 16 can flow back to the oil pan 15 through the third oil guide hole 13, and the oil can be recovered more efficiently.

Wherein, the shape of the third oil guiding hole 13 includes ellipse, circle, rectangle, square, pentagon, rounded rectangle, etc.

In some embodiments, referring to fig. 1, the arc-shaped surface 1, the first mounting surface 2, the second mounting surface 3, the plurality of guiding members 4, and the plurality of positioning members 5 are integrally injection molded.

So set up, it is simple and convenient to make, be convenient for batch production. When the engine oil baffle is installed, the guide piece 4 is only required to be inserted into the corresponding guide piece groove on the crankcase 14, and the positioning piece 5 is clamped in the corresponding positioning piece groove on the crankcase 14, so that an installation tool is not required, the operation is simple and easy, the failure rate of installation is reduced, and the cost is saved to a certain extent.

In addition, as can be understood from the perspective of the oil baffle plate in the related art, in the oil baffle plate in the related art, the oil baffle plate is fixed to the lower portion of the crankcase by means of bolts, that is, threaded holes are formed at corresponding positions of the oil baffle plate and the crankcase, and the oil baffle plate is connected to the crankcase by passing the bolts through the threaded holes and fastening the bolts. Adopt bolted connection's mode, in the installation, need operating personnel to install and fastening bolt one by one, lead to the installation to waste time and energy to in actual assembling process, bolt moment probably appears not in place, perhaps, the engine oil baffle leads to the installed part to damage because of the too big problem that leads to the baffle conquassation of bolt moment, installation cost increases. The injection molding mode of the engine oil baffle provided by the embodiment of the application replaces the injection molding mode of the bushing for meeting the bolt installation torque in the related technology, only one material is used for preparation, the risk that the engine oil baffle is cracked or the bushing falls off at the joint of the engine oil baffle and the bushing when the bushing is injected in the related technology is avoided, and the quality stability of the engine oil baffle formed by integral injection molding is better.

An embodiment of the application also provides an engine comprising the oil baffle defined in the above embodiment.

Based on having used above-mentioned machine oil baffle, separate crankcase 14 with the machine oil that is arranged in oil pan 15 for the engine is at the operation in-process, and the stirring of the bent axle 16 that is arranged in crankcase 14 and the connecting rod 17 that is connected with bent axle 16 reduces to machine oil, and simultaneously, the rotatory machine oil of throwing away of bent axle 16 and connecting rod 17 can not directly impact the liquid level of machine oil in the oil pan 15, but inside slowly the landing gets into oil pan 15 through oil pan 15 inner wall, thereby has reduced the air content of machine oil, has improved the stability of machine oil pressure.
