For satisfying the lightweight design requirement of engine, current cylinder cap guard shield is mostly the injection molding, inside integrated oil-gas separation device to arrange the machine oil filler in suitable position, filling machine oil when the auto repair maintenance of being convenient for. Under normal conditions, the cylinder cover protective cover is assembled with an engine oil inlet cover to seal the crankcase; when the engine oil needs to be filled, the engine oil can be filled by unscrewing the engine oil filling port cover. To facilitate oil filling, the oil fill port is typically in direct communication with the crankcase. Part cylinder cap guard shield can arrange the baffle in the machine oil filler hole part for preventing that the foreign matter from falling into the crankcase through the machine oil filler hole. However, in order to ensure the smoothness of oil filling, the baffle plate cannot seal the oil filling opening, and the structure can cause the problem of oil emulsification, which is caused by the following reasons: when the engine runs, high-pressure combustible mixed gas and burnt gas in the combustion chamber can more or less leak into a crankcase through a gap between the piston group and the cylinder, and blow-by gas is caused. The blow-by gas is composed of unburned hydrocarbon, steam, exhaust gas, and the like. Because the cylinder cover shield is an injection molding part, the heat transfer is slow, and the temperature rise of the engine oil filling port part is slow. When the automobile is driven for a short distance, because the temperature of the engine oil filling port of the cylinder cover shield is lower, water vapor in blow-by gas is easy to condense and form water when meeting the engine oil filling port. Along with the operation of the engine, the engine oil can splash to the engine oil filling opening part through the rotation of the timing chain or the camshaft, and is continuously attached and accumulated. The oil mixes with the condensed water to form an oil emulsion.
In view of the above, the present invention provides an engine cylinder head shield, and referring to fig. 1 to 5, the attached drawings show an embodiment of the engine cylinder head shield provided by the present invention.
Referring to fig. 1 to 3, the engine cylinder head cover 100 provided by the present invention includes a cover body 110, a fixed baffle 120 and a movable baffle 130, wherein a cavity 111 is formed inside the cover body 110, an oil inlet 112 is formed at an upper end of the cavity 111, and an oil outlet 113 for communicating with the cylinder head body is formed at a lower end of the cavity 111; the fixed baffle 120 is disposed in the cavity 111 and located below the oil inlet 112, and the fixed baffle 120 is configured to shield at least a portion of the oil inlet 112; the movable baffle 130 is disposed in the cavity 111 and located between the oil inlet 112 and the fixed baffle 120, and the movable baffle 130 covers the oil inlet 112 and can be turned downward to open the oil inlet 112 when machine oil enters the oil inlet 112 from top to bottom.
In the technical scheme provided by the invention, when the shield body 110 is filled with engine oil, the engine oil enters the oil inlet 112 from top to bottom, and exerts an external force effect on the movable baffle 130 to drive the movable baffle 130 to rotate to open the oil inlet 112, so that the engine oil can smoothly enter the cylinder cover body through the cavity 111; when the shield body 110 is not filled with engine oil, the movable baffle 130 is withdrawn under the action of external force and is reset to cover the oil inlet 112; the fixed baffle 120 shields at least part of the oil inlet 112, and the movable baffle 130 covering the oil inlet 112 can prevent the engine oil from splashing to the oil inlet 112 from the cylinder cover body, so that the engine oil emulsification is avoided.
In this design, the specific form of the shield body 110 is not limited, and any suitable size, shape and material may be used to fit the corresponding cylinder head body. The oil inlet 112 of the shroud body 110 is generally disposed through an upper end wall of the shroud body 110, having a depth. The shroud body 110 is generally provided with an oil cover 200 at the oil inlet 112, and the oil cover 200 is movably arranged and used for covering an outer port of the oil inlet 112 so as to seal oil gas in the cavity 111; and an outer port for moving to open the oil inlet 112, so that a user can add engine oil according to actual needs, and the engine oil enters the oil inlet 112 from top to bottom.
Further, in order to increase the connection sealing performance between the oil inlet 112 and the oil cover 200, a sealing ring 210 may be further disposed at the connection position of the two, and the sealing ring 210 may be optionally disposed elastically, for example, made of a rubber material.
In the present design, the oil inlet 112 and the oil outlet 113 are respectively disposed at the upper end and the lower end of the shroud body 110, so as to form an oil flow path from top to bottom, but there is no limitation on the specific installation position and the opening orientation of the oil inlet 112 and the oil outlet 113, respectively. Taking the oil inlet 112 as an example, the oil inlet 112 may be disposed on any end surface of the upper end of the shroud body 110 facing the direction; the outer port of the oil inlet 112 may be disposed upward or may be disposed in a manner of deflecting relative to the vertical direction.
The oil outlet 113 is formed at the lower end of the shield body 110 to form a connection port, a pair of ports is formed at the corresponding position of the cylinder cover body, and the connection port and the pair of ports are detachably connected to realize the connection and fixation of the shield body 110 and the cylinder cover body.
The fixed baffle 120 is disposed below the oil inlet 112 and spaced apart from the oil inlet 112, and does not interfere with the inflow of the engine oil at the oil inlet 112. During normal operation of the engine, splashed materials such as blow-by gas, engine oil or engine oil droplets and the like are splashed upwards from the crankcase to the oil inlet 112 due to rotation of the timing chain or the camshaft, and adhere to and accumulate on the inner wall of the oil inlet 112. When the ambient temperature is low, a temperature difference is formed between the inside and the outside of the shroud body 110, so that water vapor in the blow-by gas is condensed into a liquid state on the inner wall of the oil inlet 112, and the engine oil is mixed with liquid water to emulsify the engine oil. Therefore, in the embodiment, the fixed baffle 120 shields at least part of the oil inlet 112, so that the engine oil splashed upwards from the crankcase can be blocked to a certain extent, the formation amount of water vapor at the oil inlet 112 is reduced, and the problem of engine oil emulsification is effectively relieved.
Further, the movable baffle 130 covers the oil inlet 112, so that the passage of the splashed materials from the crankcase to the oil inlet 112 can be completely closed, and the splashed materials which cannot be blocked by the fixed baffle 120 are secondarily blocked, so that the problem of engine oil emulsification is completely solved; the activation of the flapper 130 is associated with the operation of filling the oil, but does not interfere with the oil filling process. The combination of the movable baffle 130 and the fixed baffle 120 not only can improve the blocking effect on the splashes, but also can help to disperse the splashes, and prevent the splashes from adhering and accumulating on the movable baffle 130 or the fixed baffle 120 to also generate oil emulsification.
The present design is to drive the flapper 130 to flip down when oil is filled, but the present design is not limited to the drive method for driving the flapper 130 to flip down. In an embodiment, the up-down turning stroke of the movable baffle 130 can be driven by additionally arranging a driver; in another embodiment, a push rod or a pull rod may be further provided to provide an auxiliary driving force for the downward tilting of the flap 130, and the like, based on the setting that the flap 130 can be driven to tilt downward by filling oil, which is not limited herein. However, for the sake of easy understanding, in the following embodiments, the flapper 130 is driven to be turned downward when oil is filled.
Further, in one embodiment, the movable baffle 130 has a connecting end 131 and a movable end 132 opposite to each other along the length direction thereof; wherein, the connecting end 131 of the movable baffle 130 is mounted on the fixed baffle 120 in a manner of being capable of turning up and down. Specifically, the connection end 131 of the flapper 130 is rotatably mounted on the inner port peripheral side of the oil inlet 112, for example, by a rotation shaft, so that the movable end 132 of the flapper 130 can be flipped up to close the oil inlet 112 or flipped down to open the oil inlet 112. The flapper 130 may be configured to have sufficient strength to extend its useful life.
Based on the above, in an embodiment, a torsion spring may be disposed at the rotating shaft, so that the turning of the movable baffle 130 has a reset function. In practical application, when an operator fills the oil from the oil inlet 112, the mass of the oil and the potential energy of the oil apply a downward pressure to the movable end 132 of the movable baffle 130, the pressure is greater than the torsion of the torsion spring, so that the movable baffle 130 turns downward to open the oil inlet 112, and the downward rotation angle of the movable baffle 130 is gradually increased, so that the filling amount of the oil is gradually increased, and the stable and efficient flow rate of the oil during filling is facilitated; when the oil is filled, the downward pressure applied to the movable end 132 of the flap 130 is removed, the torsion of the torsion spring is highlighted, and the movable end 132 of the flap 130 is driven to move upward, so that the flap 130 is reset.
Alternatively, in an embodiment, the movable baffle 130 is elastically bendable at least at the connecting end 131, so that when the engine oil enters the oil inlet 112 from top to bottom, the movable baffle 130 bends and deforms downward. Based on this, it may be provided that the connection end 131 of the flapper 130 is made of an elastic material, or that the flapper 130 is entirely made of an elastic material. So configured, it helps to simplify the structure of the flapper 130 itself, as well as simplifying the structure of the connection between the flapper 130 and the shield body 110.
Specifically, the movable baffle 130 is a metal spring. So set up for the thickness of adjustable fender 130 can set up to be thinner, helps reducing the space occupation of adjustable fender 130, and makes adjustable fender 130 have certain elastic deformation ability, helps improving the sensitivity to the pressure that applys when filling machine oil.
The specific expression form of the metal elastic sheet is not limited, and the material, shape and size of the metal elastic sheet can be set to be different according to different application requirements. For example, when the oil inlet 112 has a large size and the oil flow rate is large, the metal elastic sheet can be set to have a large thickness so as to improve the overall strength of the metal elastic sheet and prevent the metal elastic sheet from exceeding the deformation limit due to too large stress; for example, when the cross section of the oil inlet 112 is set to be different shapes, such as a circle, an ellipse, a polygon, or an irregular shape, the shape of the corresponding portion of the metal spring piece may be set to be matched with the shape of the oil inlet 112; the size of the metal elastic sheet is set to be at least larger than the sectional area of the inner port of the oil inlet 112, so that the metal elastic sheet can completely cover the inner port of the oil inlet 112.
Further, in one embodiment, the upper end surface and the lower end surface of the movable baffle 130 are disposed in a direction approaching the movable end 132. The inclined arrangement of the upper end surface of the movable baffle 130 can form a guide surface extending obliquely towards the movable end 132 of the movable baffle 130 at the upper end of the movable baffle 130, so that when oil enters the oil inlet 112, the oil gradually flows towards the movable end 132 of the movable baffle 130, the stress on the movable end 132 of the movable baffle 130 is more concentrated, and the opening sensitivity of the movable baffle 130 is enhanced; the inclined arrangement of the lower end surface of the movable baffle 130 can form a guide surface extending obliquely from the movable end 132 of the movable baffle 130 at the lower end of the movable baffle 130, so that when the splashes flow upward to the movable baffle 130, the splashes are guided to concentrate at the movable end 132 of the movable baffle 130, and the abutting force between the movable end 132 of the movable baffle 130 and the peripheral side of the inner port of the oil inlet 112 is increased, so that the covering strength of the movable baffle 130 on the oil inlet 112 is improved under the normal state of no oil filling, and the blocking effect of the movable baffle 130 on blocking the splashes from entering the oil inlet 112 is improved.
In addition, referring to fig. 5, in an embodiment, an oil groove 133 is formed in the movable baffle 130 adjacent to the movable end 132 thereof, and one end of the oil groove 133 extends to be disposed toward the movable end 132 penetrating through the movable baffle 130. The oil groove 133 is configured to contain a certain amount of oil when the oil is filled, so as to increase the force applied to the flapper 130 at the free end 132 thereof, so that the flapper 130 can be opened to a desired angle more quickly; when the movable baffle 130 is opened to a predetermined angle, oil can flow out from the oil groove 133 through one side of the movable end 132, so as to avoid oil accumulation.
Referring to fig. 4, in an embodiment, the fixed baffle 120 has an installation end 121 and a free end 122 opposite to each other along a length direction thereof, the installation end 121 of the fixed baffle 120 is installed on an upper cavity wall of the cavity 111, and the free end 122 of the fixed baffle 120 is gradually inclined downward. Due to the inclined arrangement of the fixed baffle 120, on one hand, an inclined flow guide surface can be formed, so that the engine oil entering the cavity 111 through the oil inlet 112 can flow towards the oil outlet 113 along the fixed baffle 120, and the accurate and stable flow direction of the engine oil is facilitated; on the other hand, the contact area with the spatter can be increased, so that a sufficiently large blocking area is formed. In addition, the fixed baffle 120 is inclined to limit the maximum overturning angle of the movable baffle 130, so that the movable baffle 130 is overturned within a proper angle range, and permanent deformation of the movable baffle 130 due to an overlarge opening angle is avoided.
Further, in one embodiment, the shroud body 110 has a first side plate 114, and the oil inlet 112 is disposed adjacent the first side plate 114; the free end 122 of the fixed baffle 120 is spaced from the first side plate 114 and is inclined downward in a direction close to the first side plate 114. When the fixed baffle 120 is disposed obliquely, the free end 122 of the fixed baffle 120 and the upper cavity wall of the cavity 111 jointly define an opening therebetween. When the free end 122 of the fixed baffle 120 is spaced from the first side plate 114 and is gradually inclined downwards in the direction close to the first side plate 114, so that the distance between the opening and the first side plate 114 is reduced, that is, the air passing area of the flow path through which the splashes reversely flow from the oil outlet 113 to the oil inlet 112 is firstly larger and then smaller, it can be understood that when the blow-by gas firstly passes through the flow path with the larger air passing area, the flow speed is reduced, and the power of continuously discharging upwards is reduced; when the splashes pass through the flow path with the smaller gas passing area, part of the splashes are blocked and flow back, so that more splashes are effectively prevented from approaching the oil inlet 112.
Further, in an embodiment, the movable baffle 130 is a metal elastic sheet, and a section of the movable baffle 130 is clamped and limited between the upper cavity wall of the cavity 111 and the fixed baffle 120. The movable baffle 130 is clamped and limited between the fixed baffle 120 and the upper cavity wall of the cavity 111, which is beneficial to simplifying the installation of the movable baffle 130, ensures the position between the connecting end 131 of the movable baffle 130 and the installing end 121 of the fixed baffle 120 to be fixed, and improves the limiting effect of the fixed baffle 120 when the movable baffle 130 is turned downwards. A groove 123 is arranged between the joint of the fixed baffle 120 and the movable baffle 130 and the mounting end 121 of the fixed baffle 120, and an oil passing port communicated with the cavity 111 is arranged at the bottom of the groove 123. The groove 123 is provided to accommodate the oil accumulated at the connection end 131 of the flap 130; the oil passing port is arranged, so that the engine oil contained in the groove 123 can flow downwards to the oil outlet 113, and then enters the cylinder head body through the oil outlet 113. The number of the oil passing ports can be one or more, and the oil passing ports can be randomly distributed in the groove 123, distributed in an array manner, distributed in a grid manner and the like.
Next, in the above embodiment, the fixed baffle 120 and the shield body 110, and the movable baffle 130 and the shield body 110 are detachably connected. The detachable connection of the movable baffle 130 and the fixed baffle 120 enables the movable baffle 130 and the fixed baffle 120 to be easily detached and replaced as required, thereby facilitating the maintenance and repair of the shield body 110. The specific detachable connection manner is not limited, for example, in the above embodiments, the fixing baffle 120 and the upper end wall of the shield body 110 are configured to be fixed by adhesion, screw connection, or snap connection; the flapper 130 is positioned to be sandwiched between the fixed flapper 120 and the upper end wall of the shield body 110.
In addition, in order to achieve the above object, the present invention also proposes a vehicle including the engine head cover 100 as described above. It should be noted that, for the detailed structure of the engine head cover 100 in the vehicle, reference may be made to the above-mentioned embodiment of the engine head cover 100, and details are not described herein; since the engine cylinder head shield 100 is used in the vehicle of the present invention, the embodiment of the vehicle of the present invention includes all technical solutions of all embodiments of the engine cylinder head shield 100, and the achieved technical effects are also completely the same, and are not described herein again.
