These drawings and text descriptions are not intended to limit the scope of the present disclosure in any way, but to illustrate the concepts of the present disclosure to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0033] As people's requirements for environmental protection continue to increase, vehicle fuel consumption and emission requirements are becoming more and more stringent, and the design of automotive parts is gradually becoming lighter, and the timing cover of the engine is also moving towards a trend of lightweight. The wall thickness of the timing cover is usually around 4mm to reduce the weight of the timing cover. In addition, the timing cover integrates multiple functions, such as the integrated vehicle suspension mounting boss, OCV valve (Oil Control Valve) mounting boss, scale tube, etc., to achieve the goal of lightweighting.

[0034] However, the more functions are integrated on the timing cover, the higher the requirements for the strength and rigidity of the timing cover. The timing cover in the related art has low structural strength and poor rigidity. During the long-term use of the vehicle, the timing cover is easy to deform and cause oil leakage in the engine. In severe cases, it will damage the engine and cause great economic losses.

[0035] In view of this, according to one aspect of an embodiment of the present disclosure, a timing cover is provided, which has higher strength. Figure 1 A schematic diagram of a timing cover provided for an embodiment of the present disclosure; Figure 2 Schematic diagram of a timing cover provided by an embodiment of the present disclosure. Figure 1 and 2 As shown, the timing cover provided by the embodiment of the present disclosure includes a cover body 1 and a flange 2, wherein the flange 2 is connected to at least a portion of the edge of the cover body 1; the cover body 1 has relative inner and outer sides, the outer side is provided with a curved recessed structure 101, the inner side is provided with reinforcing ribs 102, the side of the flange 2 close to the inner side has a reticular structure 201, and the flange 2 is configured to be connected to the body of the engine.

[0036] In the timing cover provided in the embodiment of the present disclosure, the outer side surface of the cover body 1 is provided with a curved concave structure 101, and the inner side surface of the timing cover 1 is provided with reinforcing ribs. Compared with the timing cover with a flat structure, the timing cover provided in the embodiment of the present disclosure has a higher mode and greater strength. Moreover, a mesh structure 201 is provided on the side of the flange 2 of the timing cover close to the inner side surface. The mesh structure 201 can accommodate the sealing colloid, so that the connection between the timing cover and the engine body is tighter, and the oil in the engine is prevented from leaking through the gap connecting the timing cover. At the same time, it can reduce the noise transmission of the engine and play a role in sound insulation and noise reduction. When the engine is working, most of the noise generated by the high-speed operation of the timing valve mechanism radiates from the front end of the timing cover. The structure of the timing cover provided in the embodiment of the present disclosure can suppress the transmission of vibration noise of the timing valve system.

[0037] In order to make the technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.

[0038] like Figure 1 As shown, the timing cover provided by the embodiment of the present disclosure includes a cover body 1 and a flange 2, and the flange 2 is connected to at least part of the edge of the cover body 1. Exemplarily, the flange 2 is respectively connected to the edges on opposite sides of the cover body 1, and the flange 2 is used to connect the timing cover to the body of the engine. The cover body 1 has relative inner and outer sides, where the inner side refers to the side close to the body of the engine, and the outer side refers to the side away from the body of the engine. The outer side surface of the cover body 1 is provided with a curved recessed structure 101, and the inner side surface is provided with reinforcing ribs 102. The recessed structure 101 and the reinforcing ribs 102 are used to improve the stress distribution of the timing cover. Compared with the timing cover of a flat plate structure, the timing cover provided by the embodiment of the present disclosure has a higher mode and greater strength. The side of the flange 2 close to the inner side has a mesh structure 201. After the flange 2 is connected to the engine body, an uneven gap can be formed between the mesh structure 201 on the side of the flange 2 close to the inner side and the engine body. The mesh structure 201 can contain a sealant or a gasket, so as to completely seal the gap between the timing cover and the engine body to prevent the oil inside the engine from leaking. In addition, the sealing structure of the flange 2 can reduce the noise transmission of the engine and play a role in sound insulation and noise reduction.

[0039] For example, the reticular structure 201 may be a plurality of grooves arranged at equal intervals along a first direction, and a plurality of grooves arranged at equal intervals along a second direction, wherein the first direction intersects the second direction. Alternatively, the cross-sectional shape of the reticular structure 201 may be a wave shape, thereby forming a regular gap between the flange 2 and the engine body.

[0040] In some embodiments of the present disclosure, Figure 1 As shown, the outer side of the cover body 1 is provided with a protrusion 107, and the protrusion 107 is provided with a threaded hole for connecting the engine mount, so that the engine is connected to the frame through the mount. The structure of the protrusion 107 can improve the stress distribution of the timing cover, which is conducive to increasing the strength of the timing cover.

[0041] In some embodiments of the present disclosure, Figure 2 As shown, the inner side of the cover body 1 is provided with a plurality of connecting parts 103, and the reinforcing ribs 102 are radially distributed with the connecting part 103 as the center. Exemplarily, the inner side of the cover body 1 is provided with three connecting parts 103, and the three connecting parts 103 are not arranged on the same straight line. A plurality of radially distributed reinforcing ribs are arranged around each connecting part 103, and the reinforcing ribs 102 extend from the connecting part 103 to the flange 2 at the edge, and two relatively close connecting parts 103 are connected by two reinforcing ribs 102. The connecting part 103 is a cylindrical structure, and the length direction of the connecting part 103 is roughly perpendicular to the plane where the cover body 1 is located. The connecting part 103 can be provided with a threaded hole, and the connecting part 103 is used to connect the timing cover 1 to the cylinder block of the engine.

[0042] In some embodiments of the present disclosure, Figure 2 As shown, the flange 2 is provided with a plurality of connection holes 205, and the flange 2 is connected to the engine body through the plurality of connection holes 205 and bolts. The engine body may be provided with a plurality of threaded holes, each of which can be aligned with a connection hole 205, so that the flange 2 can be connected to the engine body by bolts.

[0043] Alternatively, see Figure 2 , the flange 2 is also provided with a plurality of disassembly holes 206, which are through holes, and each of which is provided with an internal thread. After the timing cover is connected to the engine body, the position on the engine body opposite to the disassembly hole 206 is a closed structure. When the timing cover needs to be disassembled, after removing the bolts in the connecting holes 205, it is difficult to directly remove the timing cover due to the colloid adhesion between the flange 2 and the engine body. Therefore, a bolt can be screwed into the disassembly hole 206, and the bolt can apply a force away from the engine to the timing cover through the internal thread in the disassembly hole 206, thereby lifting the timing cover to facilitate separation of the timing cover from the engine body.

[0044] Figure 3 A schematic diagram of a timing cover provided in an embodiment of the present disclosure. In some embodiments of the present disclosure, such as Figure 3As shown, the timing cover also includes a scale 3, a flange 2 extends along the length direction of the cover body 1 and is located on opposite sides of the cover body 1, and a gantry portion 104 protruding from the end of the flange 2 is provided at one end of the cover body 1 along its length direction, and a first mounting hole 106 is provided at the end of the gantry portion 104, and the scale 3 is located in the first mounting hole 106, and the first mounting hole 106 extends to the inner side of the cover body 1. The scale 3 can be connected to the inside of the engine, so as to detect the oil level of the engine oil inside the engine, and it is easy to detect the working state of the engine and find fault problems.

[0045] In some embodiments of the present disclosure, see Figure 2 A crankshaft mounting hole 109 is provided at one end of the cover body 1 away from the gantry portion 104, and radial reinforcing ribs 102 centered on the crankshaft mounting hole 109 are provided on the inner side of the cover body 1, and reinforcing ribs 102 are provided on the upper and lower sides of the crankshaft mounting hole 109 on the inner side of the cover body 1 to increase the strength of the timing cover at the crankshaft mounting hole 109. In the direction from the gantry portion 104 to the crankshaft mounting hole 109, the width of the cover body 1 gradually decreases.

[0046] like Figure 3 As shown, after the installation is completed, one end of the scale 3 is inserted into the first installation hole 106 and is detachably connected to the scale tube 4 on the inner side of the cover body 1.

[0047] Figure 4 A partial cross-sectional view of a timing cover provided in an embodiment of the present disclosure. In some embodiments of the present disclosure, such as Figure 3 and 4 As shown, one end of the scale 3 located in the first mounting hole 106 is configured to be connected to the scale tube 4, and a chamfered structure 1061 is provided at one end of the first mounting hole 106 close to the scale tube 4. When the scale 3 is installed in the first mounting hole 106, one end of the scale 3 partially passes through the first mounting hole 106 at the chamfered structure 1061, so that when the scale 3 needs to be removed, the scale 3 can be directly pushed outward from the inner side of the cover body 1, which solves the problem of difficulty in removing the scale 3. Exemplarily, the inclination angle of the chamfered structure 1061 is 45 degrees.

[0048] Figure 5 for Figure 1 A partial schematic diagram of the timing cover a region shown in FIG. In some facts of the present disclosure, such as Figure 1 , 2 As shown in 5 , the timing cover also includes an oil pressure control valve 5 . A second mounting hole 105 is provided on the cover body 1 . The second mounting hole 105 communicates with the inner side and the outer side of the cover body 1 . The oil pressure control valve 5 is located in the second mounting hole 105 .

[0049] Specifically, see Figure 1-2 The second mounting hole 105 is arranged at the end and area a of the cover body 1. Two second mounting holes 105 are arranged at the end of the cover body 1. An arc surface recess 108 is arranged between the two second mounting holes 105. The first mounting hole 106 is located between the two second mounting holes 105. The arc surface recess 108 is used to increase the strength of the cover body 1 to prevent the arranged second mounting holes 105 from excessively reducing the strength of the timing cover.

[0050] In some facts of this disclosure, such as Figure 5 As shown, the cover body 1 is provided with a first boss 1051 at the second mounting hole 105 in area a, the surface of the first boss 1051 is provided with a first angle structure 1052, the outer wall of the oil pressure control valve 5 is provided with a second angle structure 501, and the second angle structure 501 is engaged with the first angle structure 1052. The oil pressure control valve 5 is connected to the oil pump harness 6, and when the oil pressure control valve 5 is installed in the second mounting hole 105, the second angle structure 501 abuts against the first angle structure 1052, thereby preventing the oil pressure control valve 5 from rotating relative to the cover body 1, and preventing the oil pressure control valve 5 from being loosened from the cover body 1 due to vibration.

[0051] The first angle structure 1052 and the second angle structure 501 have the same angle. For example, the angles of the first angle structure 1052 and the second angle structure 501 are both 90 degrees.

[0052] Figure 6 A partial schematic diagram of a timing cover provided in an embodiment of the present disclosure. In some implementations of the present disclosure, such as Figure 6 As shown, two second mounting holes 105 are located at the gantry portion 104, and a hydraulic control valve 5 is installed in each mounting hole 105. A second boss 1053 and a third boss 1054 are provided on the outer side of the cover body 1, two third mounting holes 1055 are provided on the second boss 1053, and two third mounting holes 1055 are provided on the third boss 1054. The line connecting the centers of the two third mounting holes 1055 on the second boss 1053 passes through the center of the second mounting hole 105, and the line connecting the centers of the two third mounting holes 1055 on the third boss 1054 passes through the center of the second mounting hole 105, and the hydraulic control valve 5 is fixedly connected to the cover body 1 through the third mounting holes 1055.

[0053] In some embodiments of the present disclosure, the average wall thickness of the cover body 1 is 2.5 mm to 3.5 mm. Preferably, the average wall thickness of the cover body 1 is 3 mm. The timing cover provided in the embodiments of the present disclosure has a protrusion 107, a recessed structure 101 and a curved recess 108 on the cover body 1, which significantly improves the modal and stress distribution of the timing cover, disrupts the vibration frequency of each position of the timing cover, prevents resonance, and can also improve the strength of the timing cover, achieving a thinner cover body 1, thereby further reducing the weight of the timing cover, which is conducive to achieving a lightweight vehicle.

[0054] It should be noted that the cover body 1 and the flange 2 involved in the embodiment of the present disclosure are integrally formed, for example, by casting, and the protrusion 107, the first boss 1051, the second boss 1053 and the first angle structure 1053 are formed by the mold during the molding process.

[0055] On the other hand, an embodiment of the present disclosure further provides an engine, which includes a body 100 , a seal 7 and any one of the timing covers in the above embodiments, wherein the seal 7 is located between the body 100 and the flange 2 .

[0056] In the engine provided by the embodiment of the present disclosure, the outer side surface of the cover body 1 is provided with a curved concave structure 101, and the inner side surface of the timing cover 1 is provided with reinforcing ribs. Compared with the timing cover of a flat structure, the timing cover provided by the embodiment of the present disclosure has a higher mode and greater strength. Moreover, a mesh structure 201 is provided on the side of the flange 2 of the timing cover close to the inner side surface. The mesh structure 201 can accommodate a sealing gasket so that the sealing gasket can fill the gap between the flange 2 and the engine body, thereby making the connection between the timing cover and the engine body tighter, preventing oil leakage in the engine, and at the same time can reduce the noise transmission of the engine, playing a role in sound insulation and noise reduction. When the engine is working, most of the noise generated by the high-speed operation of the timing valve mechanism radiates from the front end of the timing cover. The structure of the timing cover provided by the embodiment of the present disclosure can suppress the transmission of vibration noise of the timing valve system. The design of the OCV valve of the timing cover is such that the top of the timing cover has a gantry portion 104, that is, the sealing surface of the timing cover at the gantry portion 104 is not a plane, thereby ensuring good sealing performance and preventing oil leakage when the engine is working.

[0057] Figure 7 A partial cross-sectional view of an engine provided in an embodiment of the present disclosure. In some embodiments of the present disclosure, such as Figure 7As shown, the flange 2 of the timing cover is opposite to the engine body 100, and the flange 2 is connected to the engine body 100 by bolts. The cross-sectional shape of the mesh structure 201 is sawtooth-shaped, and the end surface of the engine body 100 opposite to the flange 2 is also provided with a sawtooth structure. A sealing gasket 7 is provided between the engine body 100 and the flange 2, and the sealing gasket 7 can be elastically deformed under the extrusion of the flange 2 and the engine body 100, thereby sealing the gap between the engine body 100 and the flange 2, and the mesh structure 201 with a sawtooth-shaped cross-sectional shape can increase the friction between the engine body 100 and the flange 2 and the sealing gasket 7, thereby preventing the sealing failure between the engine body 100 and the flange 2 due to the vibration of the engine.

[0058] In addition, an embodiment of the present disclosure further provides a vehicle, which includes the timing cover described in any one of the above embodiments.

[0059] In the vehicle provided in the embodiment of the present disclosure, the outer side surface of the cover body 1 is provided with a curved concave structure 101, and the inner side surface of the timing cover 1 is provided with reinforcing ribs. Compared with the timing cover of a flat structure, the timing cover provided in the embodiment of the present disclosure has a higher mode and greater strength. Moreover, a mesh structure 201 is provided on the side of the flange 2 of the timing cover close to the inner side surface. The mesh structure 201 can accommodate a gasket so that the gasket can fill the gap between the flange 2 and the engine body 100, thereby making the connection between the timing cover and the engine body 100 tighter, preventing oil leakage in the engine, and at the same time can reduce the noise transmission of the engine, playing a role in sound insulation and noise reduction. When the engine is working, most of the noise generated by the high-speed operation of the timing valve mechanism radiates from the front end of the timing cover. The structure of the timing cover provided in the embodiment of the present disclosure can suppress the transmission of vibration noise of the timing valve system. The design of the OCV valve of the timing cover is such that the top of the timing cover has a gantry portion 104, that is, the sealing surface of the timing cover at the gantry portion 104 is not a plane, thereby ensuring good sealing performance and preventing oil leakage when the engine is working.
