Guide components, water-cooled engines, and motorcycles

Abstract

The present application relates to a flow guide assembly, a water-cooled engine, and a motorcycle. The flow guide assembly includes a flow divider and a flow guide. The flow guide is disposed on the side of the flow divider and is connected to the flow divider. The flow guide is disposed within a water inlet cavity that communicates with the cooling cavity and a water inlet channel. The flow guide includes a flow guide portion. This allows coolant flowing out of the water inlet channel to flow toward the cooling cavity under the action of the flow guide portion, preventing backflow and turbulence caused by the coolant striking the walls of the water inlet cavity and colliding with the coolant flowing out of the water inlet cavity. This improves the flow efficiency of the coolant and, in turn, the cooling effect, thereby ensuring optimal performance of the water-cooled engine. Furthermore, because the flow guide is disposed within the water inlet cavity, it can partially fill the water inlet cavity, reducing the thickness of the water inlet cavity wall, preventing defects such as pores and looseness during the casting process, and improving the strength of the water-cooled engine.

Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to a flow guide component, a water-cooled engine, and a motorcycle. Background Art

[0002] Depending on the cooling medium, engines are divided into air-cooled engines and water-cooled engines, among which water-cooled engines use liquid as the cooling medium.

[0003] A water-cooled engine's cylinder body is equipped with a cooling chamber where coolant circulates to cool the cylinder body, maintaining the engine's operating temperature below a preset level and ensuring optimal performance. However, as the coolant flows through the water inlet channel into the cooling chamber, it can experience backflow and turbulence, resulting in poor cooling performance. Summary of the Invention

[0004] Based on this, it is necessary to provide a guide component, a water-cooled engine and a motorcycle to address the problem of poor cooling effect of the water-cooled engine.

[0005] A flow guide assembly, comprising:

[0006] a flow partition, the flow partition being arranged in the cooling cavity; and

[0007] A flow guide member, wherein the flow guide member is arranged on the side of the flow partition and is connected to the flow partition, and the flow guide member is used to be arranged in a water inlet cavity connected to the cooling cavity and the water inlet channel, and the flow guide member includes a flow guide portion, and the flow guide portion is used to allow the coolant flowing into the water inlet cavity through the water inlet channel to flow to the cooling cavity.

[0008] The aforementioned flow guide assembly, by providing a flow divider within the cooling chamber, blocks coolant flowing into the cooling chamber through the water inlet channel, forcing the coolant to flow in a single direction. This improves coolant flow efficiency and, in turn, the cooling effect, thereby ensuring optimal performance of the water-cooled engine. By providing the flow guide within the water inlet chamber, the coolant flowing out of the water inlet channel is directed toward the cooling chamber by the flow guide, preventing the coolant from impacting the walls of the water inlet chamber, causing backflow, turbulence, and collision with the coolant flowing out of the water inlet channel. This improves coolant flow efficiency and, in turn, the cooling effect, thereby ensuring optimal performance of the water-cooled engine. Furthermore, since the flow guide is provided within the water inlet chamber, it can partially fill the water inlet chamber, thereby reducing the thickness of the water inlet chamber wall, preventing defects such as pores and porosity during the casting process, and improving the strength of the water-cooled engine. In one embodiment, the coolant flowing into the water inlet chamber through the water inlet channel is directed in a first direction, and the flow guide is arranged obliquely relative to the first direction.

[0009] In one embodiment, the angle between the guide portion and the first direction is 100° to 130°.

[0010] In one embodiment, the flow guide further includes an assembly portion for fitting to the wall of the water inlet chamber, and the assembly portion is provided on a side of the flow guide facing the flow partition.

[0011] In one embodiment, the flow partition includes a flow partition body, which is a cone. The flow partition body also includes a second end connected to the first end, and the diameter of the flow partition body gradually decreases from the first end to the second end. The flow partition body includes a first end, and the flow guide includes a third end located at the same height as the first end. The flow guide assembly also includes a connecting member, one side of the connecting member is connected to the first end, and the other side is connected to the third end.

[0012] In one embodiment, the flow partition further includes a first limiting portion, which is provided at the first end; or, the first limiting portion is provided on the flow partition body and is located between the first end and the second end, and the first limiting portion is used to cooperate with the side wall of the cooling cavity in a limiting manner; the flow partition further includes a second limiting portion, which is provided at the second end, and the second limiting portion is used to cooperate with the bottom wall of the cooling cavity in a limiting manner.

[0013] In one embodiment, the center line of the flow partition is parallel to the center line of the flow guide; and the length of the flow guide is greater than the length of the flow partition.

[0014] A water-cooled engine, comprising:

[0015] A cylinder body, wherein the cylinder body is provided with a cooling chamber, a water inlet chamber and a water inlet channel, wherein the water inlet channel is connected to the cooling chamber through the water inlet chamber; and the above-mentioned flow guide component, wherein the flow partition is arranged in the cooling chamber, and the flow guide is arranged in the water inlet chamber.

[0016] The above-mentioned water-cooled engine, by providing a flow divider within the cooling chamber, blocks coolant flowing into the cooling chamber through the water inlet channel, forcing the coolant to flow in a single direction. This improves coolant flow efficiency, thereby enhancing the cooling effect and ensuring optimal performance of the water-cooled engine. By providing a flow guide within the water inlet chamber, coolant flowing out of the water inlet channel is directed toward the cooling chamber by the flow guide, preventing coolant from impacting the walls of the water inlet chamber, causing backflow, turbulence, and collision with coolant flowing out of the water inlet channel. This improves coolant flow efficiency and further enhances the cooling effect, thereby ensuring optimal performance of the water-cooled engine. Furthermore, since the flow guide is located within the water inlet chamber, it can partially fill the water inlet chamber, thereby reducing the thickness of the water inlet chamber wall, preventing defects such as pores and looseness during the casting process, and improving the strength of the water-cooled engine. In one embodiment, the flow divider is located within the cooling chamber near the water inlet, and the flow guide is positioned opposite the water outlet of the water inlet channel.

[0017] A motorcycle comprises the above-mentioned water-cooled engine.

[0018] The motorcycle described above utilizes a flow divider within the cooling chamber to block coolant flowing into the cooling chamber through the water inlet channel, forcing the coolant to flow in a single direction. This improves coolant flow efficiency and, in turn, enhances cooling performance, thereby ensuring optimal performance of the water-cooled engine. Furthermore, the flow guide provided within the water inlet chamber allows coolant flowing out of the water inlet channel to flow toward the cooling chamber under the influence of the flow guide. This prevents coolant from impacting the walls of the water inlet chamber, causing backflow and turbulence, and colliding with coolant flowing out of the water inlet channel. This improves coolant flow efficiency and, in turn, enhances cooling performance, thereby ensuring optimal performance of the water-cooled engine. Furthermore, since the flow guide is provided within the water inlet chamber, it can partially fill the water inlet chamber, thereby reducing the thickness of the water inlet chamber wall, preventing defects such as pores and looseness during the casting process, and enhancing the strength of the water-cooled engine.

[0023] To make the above-mentioned objects, features, and advantages of the present application more clearly understood, the specific embodiments of the present application are described in detail below with reference to the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0024] See Figure 1 , Figure 1 The schematic diagram of the structure of a water-cooled engine according to one embodiment of the present application is shown. This application provides a water-cooled engine comprising a cylinder block 10 and a water pump 20. The cylinder block 10 is provided with a cooling chamber 11 and a water inlet channel 12 communicating with the cooling chamber 11. The water outlet of the water pump 20 is communicated with the cooling chamber 11 through the water inlet channel 12.

[0025] Specifically, the cylinder block 10 comprises a cylinder body, a cylinder liner, and a water jacket. The cylinder body has an inner cavity, within which the cylinder barrel and water jacket are located. The water jacket is positioned within the cylinder barrel. The outer surface of the water jacket and the inner cavity wall form a cooling chamber 11, which is circumferentially arranged around the cylinder barrel. Furthermore, the water-cooled engine also includes a housing, which is integrally formed with the cylinder body.

[0026] When the above-mentioned water-cooled engine is working, the water pump 20 starts and injects coolant into the cooling chamber 11 through the water inlet channel 12. The coolant circulates in the cooling chamber 11 to cool the cylinder 10, so that the water-cooled engine is maintained at a preset temperature and operates below, ensuring that the water-cooled engine can perform at its best performance.

[0027] See Figure 1 and Figure 2 , Figure 1 The structure diagram of a water-cooled engine according to an embodiment of the present application is shown. Figure 2 Shown Figure 1 The cylinder body 10 further comprises a water inlet cavity 13 , through which the water inlet passage 12 communicates with the cooling cavity 11 .

[0028] In one embodiment, see Figure 1 and Figure 2 , Figure 1The structure diagram of a water-cooled engine according to an embodiment of the present application is shown. Figure 2 Shown Figure 1 A partial enlarged schematic diagram of point A of the water-cooled engine is shown. The water-cooled engine also includes a flow guide assembly 30. The flow guide assembly 30 includes a flow partition 31 and a flow guide 32 connected to the flow partition 31. The flow partition 31 is disposed within the cooling chamber 11, and the flow guide 32 is disposed within the water inlet chamber 13. The flow guide 32 includes a flow guide portion 321, which is used to direct the coolant flowing out of the water inlet channel 12 to the cooling chamber 11.

[0029] By providing a flow divider 31 within the cooling chamber 11, the flow divider 31 blocks and directs the coolant flowing into the cooling chamber 11 through the water inlet channel 12, forcing the coolant to flow in the same direction. This improves the coolant's flow efficiency and, in turn, the cooling effect, thereby ensuring optimal performance of the water-cooled engine. By providing a flow guide 32 within the water inlet chamber 13, the coolant flowing out of the water inlet channel 12 flows toward the cooling chamber 11 under the action of the flow guide 32. This prevents the coolant from striking the walls of the water inlet chamber 13, causing backflow and turbulence, and colliding with the coolant flowing out of the water inlet channel 12. This improves the coolant's flow efficiency and, in turn, the cooling effect, thereby ensuring optimal performance of the water-cooled engine. Furthermore, since the flow guide 32 is provided within the water inlet chamber 13, it can partially fill the water inlet chamber 13, reducing the wall thickness of the water inlet chamber 13, preventing defects such as pores and looseness during the casting process, and enhancing the strength of the water-cooled engine.

[0030] In this embodiment, the flow guide component 30 is made of non-metallic material.

[0031] Further, see Figure 1 and Figure 2 , Figure 1 The structure diagram of a water-cooled engine according to an embodiment of the present application is shown. Figure 2 Shown Figure 1 A partial enlarged schematic diagram of point A in FIG. A flow divider 31 is provided near the water inlet of the cooling chamber 11. Positioning the flow divider 31 near the water inlet of the cooling chamber 11 blocks and guides coolant entering the cooling chamber 11 through the water inlet, ensuring that the coolant in the cooling chamber 11 flows in the same direction. This improves coolant flow efficiency, thereby enhancing cooling effectiveness and ensuring optimal performance of the water-cooled engine.

[0032] Further, see Figure 1 and Figure 2 , Figure 1 The structure diagram of a water-cooled engine according to an embodiment of the present application is shown. Figure 2 Shown Figure 1A partial enlarged schematic diagram of point A in FIG. The guide member 32 is positioned opposite the water outlet of the water inlet channel 12. With this arrangement, the coolant flowing out of the water outlet of the water inlet channel 12 flows toward the guide member 32 and impacts it, allowing the coolant to flow into the cooling chamber 11.

[0033] In one embodiment, see Figure 2 , Figure 2 Shown Figure 1 In the partially enlarged schematic diagram at point A, the coolant flows through the water inlet channel 12 into the water inlet chamber 13 in a first direction, and the guide portion 321 is arranged at an angle relative to the first direction. As a result, due to the inclined arrangement of the guide portion 321 relative to the first direction, the coolant flowing out of the water inlet channel 12 is guided by the guide portion 321 toward the cooling chamber 11, preventing the coolant from striking the walls of the water inlet chamber 13 and then colliding with the coolant flowing out of the water inlet channel 12. This improves the flow efficiency of the coolant, thereby enhancing the cooling effect and ensuring optimal performance of the water-cooled engine.

[0034] Further, see Figure 2 , Figure 2 Shown Figure 1 A partial enlarged schematic diagram of point A. The angle between the guide portion 321 and the first direction is 100° to 130°. Optionally, the angle between the guide portion 321 and the first direction is 120°. With this definition, the coolant flowing out of the water inlet channel 12 flows toward the cooling cavity 11 under the action of the guide portion 321, avoiding the coolant colliding with the wall of the water inlet cavity 13 and then colliding with the coolant flowing out of the water inlet channel 12. This is conducive to improving the flow efficiency of the coolant, thereby improving the cooling effect, thereby ensuring that the water-cooled engine can perform at its best performance.

[0035] In one embodiment, see Figure 2 and Figure 3 , Figure 2 Shown Figure 1 A local enlarged schematic diagram of point A, Figure 3 A schematic structural diagram of a flow guide assembly according to an embodiment of the present application is shown. The flow guide member 32 further includes an assembly portion 322, which is disposed on the side of the flow guide member 321 facing the flow partition member 31 and is connected to the flow guide member 321. The assembly portion 322 is configured to fit against the wall of the water inlet chamber 13. It is understood that the assembly portion 322 is adapted to fit against the wall of the water inlet chamber 13. When the flow guide assembly 30 is installed, the assembly portion 322 of the flow guide member 32 fits against the wall of the water inlet chamber 13. This facilitates stable and reliable installation of the flow guide member 32 within the water inlet chamber 13, preventing the flow guide member 32 from shaking under the impact of the coolant flowing out of the water inlet channel 12.

[0036] In this embodiment, the assembly portion 322 is in an arc shape that protrudes away from the air guide portion 321. Of course, in other embodiments, the assembly portion 322 may also be in other shapes, and is not limited thereto.

[0037] In one embodiment, see Figure 3 , Figure 3 A schematic diagram of the structure of a flow guide assembly according to an embodiment of the present application is shown. A flow partition 31 includes a flow partition body 311, which includes a first end 3111. A flow guide 32 includes a third end 323, which is located at the same height as the first end 3111. The flow guide assembly 30 also includes a connector 33, one side of which is connected to the first end 3111 and the other side to the third end 323. Specifically, the connector 33 is connected to the assembly portion 322 of the flow guide 32. Thus, the connector 33 connects the flow partition 31 and the flow guide 32 together to form a single unit, making it easy to use.

[0038] It should be noted that the connector 33 can be a separate component, and the connector 33 is assembled into a whole with the flow guide 32 and the flow partition 31. Alternatively, the connector 33, the flow partition 31 and the flow guide 32 are integrally formed.

[0039] In one embodiment, see Figure 3 , Figure 3 A schematic diagram of the flow guide assembly according to one embodiment of the present application is shown. The flow divider 311 is a conical body. The flow divider 311 also includes a second end 3112 connected to the first end 3111. The diameter of the flow divider 311 gradually decreases from the first end 3111 to the second end 3112. Because the housing is die-cast and the outer surface of the water-cooled engine housing has a draft angle, the flow divider 311 is formed into a cone.

[0040] In one embodiment, see Figure 2 and Figure 3 The flow partition 31 also includes a first stopper 312. Optionally, the first stopper 312 is a stopper block, a stopper plate, or the like. The first stopper 312 is disposed at the first end 3111 of the flow partition body 311; alternatively, the first stopper 312 is disposed around the flow partition body 311, that is, between the first end 3111 and the second end 3112 of the flow partition body 311. After the flow partition 31 is inserted into the cooling chamber 11, the first stopper 312 abuts against the walls of the cooling chamber 11, effectively preventing the flow partition 311 from rotating under the influence of the coolant.

[0041] Further, see Figure 3The flow partition 31 also includes a second stopper 313, which is disposed at the second end 3112 of the flow partition body 311. Optionally, the second stopper 313 is a stopper block. After the flow partition 31 is inserted into the cooling chamber 11, the second stopper 313 engages with the bottom of the cooling chamber 11 to prevent the flow partition 31 from moving axially within the cooling chamber 11.

[0042] In one embodiment, see Figure 3 , Figure 3 The schematic diagram of the structure of the flow guide assembly according to one embodiment of the present application is shown, in which the center line of the flow partition 31 is parallel to the center line of the flow guide 32. This arrangement facilitates the assembly of the flow guide assembly 30.

[0043] In one embodiment, see Figure 3 , Figure 3 A schematic diagram of the structure of a flow guide assembly according to an embodiment of the present application is shown. The length of the flow guide 32 is greater than that of the flow partition 31. During installation, the flow partition 31 and the flow guide 32 are inserted into the cooling chamber 11 and the water inlet chamber 13, respectively. Because the water inlet chamber 13 is deeper than the cooling chamber 11, the length of the flow guide 32 is greater than that of the flow partition 31. This allows the second end 3112 of the flow partition body 311 to abut the bottom of the cooling chamber 11, improving water isolation. Simultaneously, the end of the flow guide 32, away from the third end 323, can also abut the bottom of the water inlet chamber 13, further improving the flow diversion effect.

[0044] A motorcycle provided in one embodiment of the present application includes a water-cooled engine according to any of the above embodiments.

[0045] The motorcycle described above utilizes a flow divider 31 disposed within the cooling chamber 11 to block coolant flowing into the cooling chamber 11 through the water inlet channel 12, forcing the coolant to flow in a single direction. This improves coolant flow efficiency and, in turn, enhances cooling performance, thereby ensuring optimal performance of the water-cooled engine. Furthermore, a flow guide 32 is disposed within the water inlet chamber 13, allowing coolant flowing out of the water inlet channel 12 to flow toward the cooling chamber 11 under the action of the flow guide 32. This prevents coolant from colliding with the walls of the water inlet chamber 13 and then colliding with the coolant flowing out of the water inlet channel 12. This improves coolant flow efficiency and, in turn, enhances cooling performance, thereby ensuring optimal performance of the water-cooled engine. Furthermore, since the flow guide 32 is disposed within the water inlet chamber 13, it can partially fill the water inlet chamber 13, thereby reducing the wall thickness of the water inlet chamber 13, preventing defects such as pores and looseness during the casting process, and enhancing the strength of the water-cooled engine.
