Description
Technical Field
[0001] The utility model relates to the technical field of vehicle parts, and in particular to an engine cylinder head cover, an engine and a vehicle. Background Art
[0002] In the field of vehicle engines, the oil filling port is generally set on the cylinder head cover (Valve Cover) to facilitate refueling and maintenance. Setting the oil filling port on the cylinder head cover can make refueling more convenient, and it also allows users to easily check the oil level and add oil. This design makes vehicle maintenance easier and reduces the difficulty of refueling. In addition, setting the oil filling port on the cylinder head cover is also conducive to reducing the possibility of oil leakage. Since the cylinder head cover is located above the valve and valve mechanism, the oil usually circulates in this area. Setting the oil filling port directly on the cylinder head cover can better control and manage the flow of oil and avoid unnecessary leakage.
[0003] On the other hand, in order to ensure the normal operation of the engine, many rotating parts of the engine need oil lubrication, and the inner side of the cylinder head cover has a rotating part that needs lubrication, namely the camshaft. In other words, the cylinder head cover is provided on the camshaft and other structures. In the case of low ambient temperature such as winter, when the engine is not fully warmed up after running for a short time, the temperature at the oil filling port is affected by the low ambient temperature, and the temperature at the oil filling port is also relatively low; the water vapor in the engine crankcase due to "blowby" is cold when it contacts the oil filling port cover, and the water vapor will condense here and gather on the oil filling port cover. In addition, the camshaft on the inner side of the cylinder head cover and below the oil filling port will throw some oil to the upper oil filling port cover due to rotation, that is, the oil at the camshaft will splash to the upper oil filling port cover under centrifugal force, resulting in the oil and condensed water forming more emulsions at the oil filling port cover.
[0004] The formation of emulsions generally does not affect the normal operation of the engine. However, if a large amount of emulsions accumulate on the oil filler cap, when the user or maintenance personnel removes the oil filler cap, it will reduce the customer experience and may also cause misjudgment by after-sales maintenance personnel. For example, the user or after-sales maintenance personnel may think that the engine is faulty or that there is a problem with the performance of the oil. Utility Model Content
[0005] The utility model aims to solve the problem that a lot of emulsions are easily gathered on the existing engine oil filling port cover.
[0006] To solve the above problems, the utility model provides an engine cylinder head cover, including a cylinder head cover body, the cylinder head cover body including a first cover wall portion provided with an oil filling port and a second cover wall portion arranged at an angle to the first cover wall portion, the engine cylinder head cover also includes a shielding member, the shielding member is located on the inner side of the cylinder head cover body and connected to the cylinder head cover body, the shielding member includes a first plate body and a second plate body arranged at an angle, the first plate body shields at least part of the oil filling port, the second plate body is arranged opposite to the second cover wall portion, and an oil channel body is formed between the second plate body and the second cover wall portion, one end of the oil channel body is connected to the oil filling port, and the other end of the oil channel body is an oil outlet.
[0007] The engine cylinder head cover provided by the utility model has, compared with the prior art, the following technical effects but not limited to:
[0008] When the oil does not need to be added, the oil port cover can be installed at the oil filling port to block the oil filling port. Different from the prior art, the cylinder head cover body and the shielding member of the utility model together form the engine cylinder head cover, which is used to be installed on the cylinder head and cover the camshaft. Among them, the shielding member includes a first plate body and a second plate body arranged at an angle, and the first plate body can block at least a part of the oil filling port at the first cover wall part from the inner side of the cylinder head cover body, which is equivalent to blocking at least a part of the oil filler port cover at the oil filling port; when the camshaft is lubricated by oil, the oil is difficult to directly splash onto the oil filler port cover in the oil filling port under the centrifugal force of the rotation of the camshaft (at least it cannot splash onto the oil filler port cover to a large extent), but is blocked by the first plate body (at least a part of the splashed oil will be blocked by the shielding member); in addition, the second plate body of the shielding member is also arranged opposite to the second cover wall part, and an oil channel body is formed between the second plate body and the second cover wall part, one end of the oil channel body is connected to the oil filling port and the other end is provided with an oil outlet, so that the oil injected from the oil filling port can enter the oil channel body and flow downward along the second cover wall part, and then flow out from the oil outlet at the other end of the oil channel body, which can ensure smooth oil filling. In addition, since the second plate body can at least block the area of the second cover wall portion close to the first cover wall portion, this can to a certain extent prevent the oil thrown off by the camshaft from indirectly splashing onto the oil filler cover due to the change of direction after being thrown to the second cover wall portion. Ultimately, through the joint shielding effect of the first plate body and the second plate body, the formation of emulsions on the oil filler cover can be greatly reduced or even avoided.
[0009] Furthermore, the first plate body is arranged opposite to the engine oil filling port, and an oil flow space is formed between the first plate body and the first cover wall portion, wherein the oil channel body is connected to the engine oil filling port through the oil flow space.
[0010] Furthermore, the shielding member also includes a first side wall arranged along a partial edge of the first plate body, the first side wall extends in the direction of the engine oil filling port and is connected to the first cover wall portion, the first side wall and the first plate body form an oil passing gap, wherein the oil channel body is connected to the engine oil filling port through the oil passing gap and the oil passing space in sequence.
[0011] Furthermore, a cover protrusion corresponding to the first side wall is arranged on the inner side of the first cover wall portion, and the cover protrusion is arranged around the oil filling port, and a first sealing groove is arranged at one end of the first side wall facing the cover protrusion, and the cover protrusion extends into the first sealing groove.
[0012] Furthermore, the shielding member also includes a second side wall arranged along the opposite side edges of the second plate body, the end of the second side wall away from the second plate body is connected to the second cover wall portion, and the end of the second side wall close to the first plate body is connected to the first side wall at the oil-passing notch.

[0030] It should also be noted that the aforementioned X-axis, Y-axis and Z-axis are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0031] See also Figure 1-3 An engine cylinder head cover of an embodiment of the utility model comprises a cylinder head cover body 1, wherein the cylinder head cover body 1 comprises a first cover wall portion 11 provided with an oil filling port 111 and a second cover wall portion 12 arranged at an angle to the first cover wall portion 11, the engine cylinder head cover further comprises a shielding member 2, wherein the shielding member 2 is located at the inner side of the cylinder head cover body 1 and is connected to the cylinder head cover body 1, the shielding member 2 comprises a first plate body 21 and a second plate body 22 arranged at an angle, the first plate body 21 shields at least part of the oil filling port 111, the second plate body 22 is arranged opposite to the second cover wall portion 12, and an oil channel body 4 is formed between the second plate body 22 and the second cover wall portion 12, one end of the oil channel body 4 is connected to the oil filling port 111, and the other end of the oil channel body 4 is an oil outlet.
[0032] In this embodiment, when it is not necessary to add oil, the oil port cover 3 can be installed at the oil filling port 111 to block the oil filling port 111. Different from the prior art, the cylinder head cover body 1 and the shielding member 2 of the utility model together constitute the engine cylinder head cover, which is used to be installed on the cylinder head and cover the camshaft 6.
[0033] The shielding member 2 includes a first plate body 21 and a second plate body 22 which are arranged at an angle. The first plate body 21 can shield at least a portion of the oil filling port 111 at the first cover wall portion 11 from the inner side of the cylinder head cover body 1, which is equivalent to shielding at least a portion of the oil filler cap 3 at the oil filling port 111. When the camshaft 6 is lubricated with oil, the oil is difficult to directly splash onto the oil filler cap 3 in the oil filling port 111 (at least it is impossible to splash onto the oil filler cap 3 to a large extent) under the centrifugal force of the rotation of the camshaft 6, but is blocked by the first plate body 21. In addition, the second plate 22 of the shielding member 2 is also arranged opposite to the second cover wall portion 12, and an oil channel body 4 is formed between the second plate 22 and the second cover wall portion 12, one end of the oil channel body 4 is connected to the oil filling port 111 and the other end is provided with an oil outlet, so that the oil injected from the oil filling port 111 can enter the oil channel body 4 and flow downward along the second cover wall portion 12, and then flow out from the oil outlet at the other end of the oil channel body 4, which can ensure smooth oil filling. In addition, since the second plate 22 can at least block the area of the second cover wall portion 12 close to the first cover wall portion 11, in this way, the oil thrown off by the camshaft 6 can be prevented from indirectly splashing onto the oil port cover 3 due to the change of direction after being thrown to the second cover wall portion 12. Finally, through the joint shielding effect of the first plate 21 and the second plate 22, the formation of emulsions on the oil port cover 3 can be greatly reduced or even avoided.
[0034] In this embodiment, as mentioned above, the engine cylinder head cover can reduce or even avoid the accumulation of emulsions on the oil filling port 111 without affecting the oil filling, which can improve the user experience and prevent customers and maintenance personnel from misjudging the problem. Moreover, the above problem can be solved by simply setting a shielding member 2 below the oil filling port 111, which has a simple structure and low cost.
[0035] In addition, after adopting the engine cylinder head cover provided by this embodiment, there is no need to change the design of the oil port cover 3 itself. The oil port cover 3 can adopt a traditional relatively simple structure, thereby facilitating the disassembly and assembly of the oil port cover 3. Figure 1-2 and Figure 4-5 As shown, the oil port cover 3 includes a hollow columnar portion, and a sealing ring is provided on the outer peripheral side of the columnar portion. After the columnar portion is inserted into the oil filling port 111, sealing is achieved through the sealing ring.
[0036] Alternatively, see Figure 2-3 The first cover wall portion 11 is the top wall of the cylinder head cover body 1, the second cover wall portion 12 is one of the peripheral side walls of the cylinder head cover body 1, and a second sealing groove 121 is provided at the bottom end of the second cover wall portion 12, wherein one end of the second plate body 22 away from the first plate body 21 is flush with the bottom surface of the second sealing groove 121.
[0037] It should be noted that the cylinder head of the engine is generally located at the top of the engine, and accordingly, the engine cylinder head cover is installed at the top of the cylinder head and covers the camshaft 6. In this embodiment, the first cover wall portion 11 provided with the oil filling port 111 is preferably the top wall of the cylinder head cover body 1, so that the oil filling port 111 is located at the top of the cylinder head cover body 1, thereby facilitating refueling and maintenance; the second cover wall portion 12 can be one of the side walls of the cylinder head cover body 1, for example, the second cover wall portion 12 is the right wall of the cylinder head cover body 1, on this basis, the oil outlet of the oil channel body 4 is located at the bottom of the oil channel body 4, when adding oil, the oil entering the oil filling port 111 can eventually flow out from the oil outlet at the bottom of the oil channel body 4 under gravity, ensuring smooth refueling.
[0038] Among them, it can be understood that the peripheral side wall of the cylinder head cover body 1 is a circle of side walls jointly composed of the right side wall, the left side wall, the front side wall and the right side wall. Since the cylinder head cover body 1 is installed on the cylinder head, in order to ensure the sealing of the connection, it is preferred to provide a second sealing groove 121 at the bottom end of the right side wall, the left side wall, the front side wall and the rear side wall, respectively, and then a sealing structure can be provided in the second sealing groove 121 to achieve the sealing between the cylinder head cover body 1 and the cylinder head to prevent oil leakage. On this basis, one end of the second plate body 22 away from the first plate body 21 (i.e., the bottom end of the second plate body 22) is flush with the bottom surface of the second sealing groove 121. In this way, it can be ensured that there is a gap between the bottom end of the second plate body 22 at this position and the cylinder head below, that is, it can be ensured that the oil outlet at the bottom end of the oil channel body 4 will not be blocked by the cylinder head, thereby ensuring that the oil can flow smoothly into the engine from the oil outlet when adding oil; moreover, the bottom end of the second plate body 22 at this position has almost extended to the bottom end of the second cover wall part 12. In this way, the second plate body 22 with a larger vertical dimension can block more of the second cover wall part 12, and to a greater extent avoid the oil thrown off by the camshaft 6 from indirectly splashing onto the oil port cover 3 due to the change of direction after being thrown to the second cover wall part 12, and finally further avoid the formation of emulsions on the oil port cover 3.
[0039] Specifically, Figure 2-3 As shown, in some prior arts, the clockwise rotating camshaft 6 is generally located at the lower left of the oil filling port 111. At this time, when the camshaft 6 rotates clockwise, the oil cannot splash to the second cover wall portion 12 under the action of centrifugal force, but will be blocked by the second plate body 22, ensuring that emulsion will not be formed in the second cover wall portion 12, ensuring that when the oil filler cap 3 is removed, not only is there no emulsion on the oil filler cap 3, but there is no emulsion in the second cover body portion 12, so that users and maintenance personnel will not see the emulsion through the oil filling port 111, thereby improving the experience and not causing misjudgment of engine performance or oil performance due to seeing the emulsion.
[0040] See also Figure 2-5 Optionally, the first plate body 21 is arranged opposite to the engine oil filling port 111, and an oil flow space 7 is formed between the first plate body 21 and the first cover wall portion 11, wherein the oil channel body 4 is connected to the engine oil filling port 111 through the oil flow space 7.
[0041] In this embodiment, the first plate 21 is arranged opposite to the oil filling port 111 of the first cover wall portion 11 to cover the oil filling port 111. The first plate 21 is arranged opposite to the oil filling port 111, that is, there is a gap between the first plate 21 and the bottom of the oil filling port 111, that is, there is a gap between the first plate 21 and the first cover wall portion 11, and the gap is the oil passage space 7. When oil needs to be refueled, the oil first enters the oil passage space 7 from the oil filling port 111, and then can enter the oil channel body 4 between the second plate 22 and the second cover wall portion 12, and finally enters the oil pan of the engine from the oil outlet.
[0042] Among them, in this embodiment, since the first plate body 21 is not directly attached to the bottom end of the oil filling port 111 to cover part of the oil filling port 111, the first plate body 21 is spaced apart from the bottom end of the oil filling port 111 to form an oil flow space 7 between the first cover wall portion 11, the high efficiency of oil filling can be ensured without affecting the refueling speed.
[0043] Of course, in other embodiments, the first plate body 21 may not be arranged opposite to the first cover wall portion 11, but directly fits the bottom end of the oil filling port 111, but does not completely cover the oil filling port 111. At this time, the oil channel body 4 is directly connected to the oil filling port 111.
[0044] See also Figure 4 Optionally, the shielding member 2 also includes a first side wall 23 arranged along a partial edge of the first plate body 21, the first side wall 23 extends in the direction of the engine oil filling port 111 and is connected to the first cover wall portion 11, the first side wall 23 and the first plate body 21 form an oil passing notch 5, wherein the oil channel body 4 is connected to the engine oil filling port 111 through the oil passing notch 5 and the oil passing space 7 in sequence, and the oil channel body 4, the oil passing notch 5 and the oil passing space 7 together constitute an oil channel for oil to pass through.
[0045] In this embodiment, as mentioned above, the first plate body 21 is arranged opposite to the oil filling port 111, that is, the first plate body 21 and the bottom end of the oil filling port 111 are spaced apart. In order to fix the first plate body 21, the first side wall 23 is connected and fixed to the first cover wall portion 11.
[0046] Among them, a first side wall 23 is disposed upwardly on a portion of the edge of the first plate body 21, and an oil-passing notch 5 is formed at the first side wall 23 and the edge of other portions of the first plate body 21. Thus, when the first side wall 23 is connected and fixed to the first cover wall portion 11, the engine oil falling onto the first plate body 21 (or the engine oil falling into the oil-passing space) can flow downwardly from the oil-passing notch 5 into the oil channel body 4, and finally flow out from the oil outlet at the bottom end of the oil channel body 4 and be stored in the oil pan. Moreover, the provision of the first side wall 23 can prevent the engine oil splashing up from the camshaft 6 from entering the engine oil filling port 111 from the oil-passing space 7, and further avoid the formation of emulsions on the engine oil port cover 3.
[0047] See also Figure 4-5 Optionally, a cover protrusion 112 corresponding to the first side wall 23 is provided on the inner side of the first cover wall portion 11, and the cover protrusion 112 is arranged around the oil filling port 111, and a first sealing groove 231 is provided at one end of the first side wall 23 facing the cover protrusion 112, and the cover protrusion 112 extends into the first sealing groove 231.
[0048] In this embodiment, before the shielding member 2 is installed and fixed to the cylinder head cover body 1, the upper end of the first side wall 23 has a first sealing groove 231, and the inner side of the first cover wall portion 11 has a cover protrusion 112 corresponding to the first sealing groove 231. The cover protrusion 112 can extend into the first sealing groove 231 and melt in the first sealing groove 231 through welding, so that the first side wall 23 and the first cover wall portion 11 can be fixed and sealed, ensuring that the engine oil splashed from the camshaft 6 position will not enter the oil filling port 111 between the first side wall 23 and the first cover wall portion 11, and will not adhere to the oil filler cover 3.
[0049] See also Figure 4-5 Optionally, the shielding member also includes a second side wall 24 arranged along the opposite side edges of the second plate body 22, and the end of the second side wall 24 away from the second plate body 22 is connected to the second cover wall portion 12, and the end of the second side wall 24 close to the first plate body 21 is connected to the first side wall 23 at the oil-passing notch 5.
[0050] In this embodiment, the second side walls 24 facing the second cover wall portion 12 are respectively provided on the front and rear sides of the second plate body 22, and one end of the second side wall 24 away from the second plate body 22 is connected to the second cover wall portion 12, and the top of the second side wall 24 is connected to the first side wall 23 at the oil notch 5. In this way, when adding engine oil, it is ensured that the engine oil can only flow out from the oil outlet at the bottom end of the oil channel body 4, which can ensure that the engine oil enters the oil pan smoothly, and also ensure that the engine oil will not splash from the front and rear sides of the second plate body 22 to the second cover wall portion 12.
[0051] See also Figure 2-3 Optionally, the first plate body 21 is arranged at an angle with a horizontal plane, and / or an end of the second plate body 22 away from the first plate body 21 is inclined toward the second cover wall portion 12.
[0052] In this embodiment, the first plate 21 is arranged at an angle to the horizontal plane. Specifically, the end of the first plate 21 away from the second plate 22 is higher than the end where the first plate 21 and the second plate 22 are connected. Figure 2-3 That is to say, the left end of the first plate body 21 is higher than the right end. In this way, when adding engine oil, it can be ensured that the engine oil falling into the oil flow space can smoothly flow to the oil flow gap 5 along the inclined direction of the first plate body 21, and then along the inclined direction of the second plate body 22 and finally flow out from the oil outlet at the bottom end of the oil channel body 4, making refueling smoother and faster.
[0053] Moreover, in this embodiment, the bottom end of the second plate body 22 is inclined toward the second cover wall portion 12, so that the camshaft 6 and other structural parts on the left side can be avoided, ensuring that the camshaft 6 and other structural parts have enough installation space.
[0054] See also Figure 2-3 Optionally, a rounded corner structure is provided between the first plate body 21 and the second plate body 22 .
[0055] In this embodiment, a rounded structure is provided between the first plate body 21 and the second plate body 22, so that the engine oil falling onto the first plate body 21 can smoothly enter the oil channel body 4, that is, the setting of the rounded structure can ensure that the engine oil can smoothly flow down from the first plate body 21.
