Description

Technical Field

[0001] The utility model particularly relates to an engine cover and an engine comprising the engine cover. Background Art

[0002] The engine hood is a cover that covers the engine block, preventing foreign matter from entering the engine. To facilitate adding oil to the crankcase, an oil filler port is provided. The oil filler cap is used to block the filler port after filling, preventing the oil from coming into contact with air and leaking out.

[0003] When the crankcase is working, the engine oil will be thrown away, causing splashing oil droplets to splash onto the bottom of the oil filler cap. The oil filler cap will be opened every time the engine oil is changed, which increases the frequency of contact between the oil filler cap and the air and liquid. As a result, the oil splashed on the bottom of the oil filler cap will come into contact with impurities, causing the oil to emulsify and turn white. If it is not cleaned in time, it will affect the oil in the engine during subsequent use, and eventually cause engine failure. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to help those skilled in the art better understand the technical solutions of the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0026] The engine in this embodiment has Figures 1 to 2 The engine hood shown. The engine hood includes a hood body 1 and a first cover plate 4, a second cover plate 5 and a pipe joint 2 which are mounted on the hood body 1. A low-load cavity for the oil and gas generated by the engine to circulate is formed between the hood body 1 and the first cover plate 4; a high-load cavity for the oil and gas generated by the engine to circulate is formed between the hood body 1 and the second cover plate 5; and the pipe joint 2 is used to discharge the exhaust gas generated in the hood body 1 to the outside. An oil port is also provided on the hood body 1, and an oil port cover 3 is provided on the oil port. The oil port cover 3 is located on the outer wall of the hood body 1 to block the oil port, prevent the oil from contacting the air, and prevent the oil from flowing out. In this embodiment, an oil baffle plate 6 is also fixedly provided on the oil port. The oil baffle plate 6 is fixedly provided on the inner wall of the hood body 1 to block the crankcase from the oil port cover 3.

[0027] Specifically, if Figure 1 、 Figures 3 to 6 As shown, the oil baffle cover 6 includes a base and an extension located above the base, and the extension extends from the top surface of the base to the side away from the oil port. The base includes a top plate 611, a first vertical plate 612, a connecting plate 613, a second vertical plate 614 and a third vertical plate 615. The top plate 611 is located above the end of the oil port away from the oil port cover 3, that is, there is a gap between the top plate 611 and the oil port to ensure the circulation of the oil. The first vertical plate 612 is fixedly provided on one side of the bottom surface of the top plate 611, and a connecting plate 613 is provided at each end of the bottom surface of the top plate 611. The second vertical plate 614 and the third vertical plate 615 are respectively fixedly connected to the ends of the two connecting plates 613 away from the first vertical plate 612. The ends of the second vertical plate 614 and the third vertical plate 615 away from the connecting plate 613 are both in contact with the inner wall of the cover body 1.

[0028] In addition, the base also includes a first stop bar 616, a connecting bar 617, a second stop bar 618, and a third stop bar 619. A connecting bar 617 is provided at each end of the first stop bar 616, and the second stop bar 618 and the third stop bar 619 are respectively fixedly connected to the ends of the two connecting bars 617 away from the first stop bar 616. The first stop bar 616, the two connecting bars 617, the second stop bar 618, and the third stop bar 619 together form an annular bar. The inner side of the annular bar is fixedly connected to the outer walls of the first vertical plate 612, the second vertical plate 614, the third vertical plate 615, and the two connecting plates 613. The bottom surfaces of the first vertical plate 612, the second vertical plate 614, the third vertical plate 615, and the two connecting plates 613 are all located below the bottom surface of the annular bar. A vertical piece 620 is fixedly provided on the outside of the annular strip. The shape of the vertical piece 620 is the same as the outline shape of the outer side of the annular strip. Both ends of the vertical piece 620 and the ends of the second and third baffles 618 and 619 away from the connecting strip 617 are also in contact with the inner wall of the cover body 1.

[0029] Furthermore, in this embodiment, the length of the third vertical plate 615 is greater than the length of the second vertical plate 614, and the bottom edges of the second vertical plate 614 and the third vertical plate 615 are inclined upward from the plane where the bottom edge of the first vertical plate 612 is located toward the direction of the inner wall of the cover body 1, and the two connecting plates 613 are both arc-shaped; the length of the third baffle 619 is greater than the length of the second baffle 618, and the two connecting bars 617 are also arc-shaped, and the second baffle 618 and the third baffle 619 are also inclined upward from the bottom surface of the first baffle 616 toward the direction of the inner wall of the cover body 1. Such settings are all for the purpose of enabling the base to better fit and be fixedly connected to the inner wall of the cover body 1, and are designed in accordance with the structure of the inner wall of the cover body 1 itself. When the oil baffle cover 6 is connected to the inner wall of the cover body 1, the bottom edge of the vertical piece 620 and the bottom edges of the first vertical plate 612, the second vertical plate 614, the third vertical plate 615 and the two connecting plates 613 are all fitted and connected to the bottom surface of the inner wall of the cover body 1.

[0030] Furthermore, the extension portion includes a vertical plate 621, a side plate 622, a first baffle 623, a second baffle 624, and a third baffle 625. A transition arc 626 extends from the inner wall of the vertical plate 621, near the oil port, toward the side of the top plate 611 away from the first vertical plate 612. This transition arc 626 is used to connect the vertical plate 621 and the top plate 611. The side plate 622 is fixedly connected to the side of the vertical plate 621 near the third vertical plate 615. The bottom edge of the side plate 622 is fixedly connected to the top edge of the third vertical plate 615. The bottom edge of the first baffle 623 is fixedly connected to the top edge of the second vertical plate 614. The first baffle 623 and the second baffle 624 are both located on the side of the vertical plate 621 away from the side plate 622. The sides of the side plate 622, the first baffle 623, and the second baffle 624 away from the vertical plate 621 all abut against the side surface of the inner wall of the cover body 1.

[0031] The first blocking piece 623 is tilted and located below the second blocking piece 624 . The top edge of the first blocking piece 623 is fixedly connected to the bottom edge of the second blocking piece 624 . Specifically, the side of the vertical plate 621 away from the side plate 622 includes, from top to bottom, a first side L1, a second side L2, a third side L3 and a fourth side L4. The side of the first baffle 623 away from the side of the inner wall of the cover body 1 is fixedly connected to the fourth side L4 of the vertical plate 621; the side of the third baffle 625 away from the second baffle 624 is fixedly connected to the first side L1 of the vertical plate 621, the bottom edge of the third baffle 625 is fixedly connected to the second side L2 of the vertical plate 621, and the top edge of the third baffle 625 is flush with the top edges of the vertical plate 621 and the side plate 622; a portion (lower end) of the side of the second baffle 624 away from the side of the inner wall of the cover body 1 is fixedly connected to the third side L3 of the vertical plate 621, and the remaining portion (upper end) of the side of the second baffle 624 away from the side of the inner wall of the cover body 1 is fixedly connected to the side of the third baffle 625 away from the side plate 622.

[0032] The top plate 611 is located above the end of the oil port away from the oil port cover 3, and the side plate 622, the first baffle 623 and the second baffle 624 away from the vertical plate 621 are all in contact with the inner wall of the cover body 1. There is a gap between the vertical plate 621 and the third baffle 625 and the inner wall of the cover body 1, so that a space for accommodating one end of the oil port is formed between the entire base and the inner wall of the extension part, and the space is connected to the oil port to ensure that the oil can flow when oil is filled from the oil port; at the same time, the oil port is located in the space formed between the base and the inner wall of the extension part, separating the oil port cover 3 from the crankcase.

[0033] Specifically, the third baffle 625 is arc-shaped, and the third baffle 625 is recessed inward from the outer wall surface of the vertical plate 621. The arc-shaped setting of the third baffle 625 and the setting of the transition arc surface 626 between the vertical plate 621 and the top plate 611 jointly play a drainage role, thereby preventing the oil from splashing out due to the excessive filling speed during the oil filling process.

[0034] In this embodiment, the oil baffle plate 6 is equivalent to setting a barrier between the crankcase and the oil port, which can well separate the bottom of the oil port cover 3 from the crankcase. When the engine is running, the high-speed rotation of the camshaft in the crankcase will throw the oil away, and the splashing oil droplets can only splash on the outer wall of the base and the extension part, but will not splash on the bottom of the oil port cover 3. The oil baffle plate 6 is located inside the cover body 1. Unlike the oil port cover 3, the oil baffle plate 6 does not need to be removed, thereby reducing the contact between the oil and the air, and avoiding the emulsification of the oil and causing engine failure.

[0035] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of protection of the present invention.
