[0023] As the power mechanism for the motorcycle to move forward, the motorcycle engine is usually installed at the bottom of the frame. The engine cover must be adapted to the engine model, and external reinforcement ribs are set to ensure the structural strength. The engine is always exposed to the outside. When it rains, the complex and tortuous surface of the cover is prone to residual water. Rainwater is corrosive, which will affect the service life of the engine cover and even affect the engine performance, which is not conducive to use.

[0024] For this purpose, refer to Figure 1 and Figure 2, is a motorcycle engine cover proposed by the utility model, including a main body 100 with a hood structure, which is used to cover one side of the motorcycle engine. The top surface of the main body 100 is similar to a conical structure, which is inclined downward from the highest point toward both sides. A first protrusion 200 is provided in the middle of the main body 100, and the first protrusion 200 is inclined from the main body 100 toward the outside to form a guide surface 210. The guide surface 210 is arranged in an arc shape, and the guide surface 210 is inclined downward from the upper side of the main body 100. The guide surface 210 is arranged at the upper end and at least one side of the main body 100 to guide rainwater to flow down. A step 220 is formed between the first protrusion 200 and the outer surface of the main body 100, and the step 220 is located at the lower side of the first protrusion 200. The outer surface of the main body 100 is provided with a plurality of external reinforcing ribs, and the plurality of external reinforcing ribs are all located below the step 220. It is understandable that the top surface of the main body 100 adopts a similar cone structure, so that rainwater can quickly gather on the top surface and flow down along the inclined surfaces on both sides. The first raised portion 200 and its guide surface 210 set in the middle can further guide rainwater to flow down along the guide surface 210 set in an arc shape, which not only speeds up the drainage speed, but also ensures that rainwater can flow down smoothly from the upper end and at least one side of the hood, effectively preventing rainwater from accumulating or remaining on the surface of the hood. This design not only ensures the stability of the engine working on rainy days, but also reduces the erosion of rainwater on the hood material, thereby improving the performance and durability of the hood. Several external reinforcement ribs are set on the outer surface of the hood main body 100. These reinforcement ribs not only enhance the overall structural strength of the hood, improve its impact resistance and vibration resistance, but also the design located below the step 220 can effectively prevent rainwater from penetrating into the hood, reducing corrosion and aging problems caused by a humid environment. The structural design of the main body 100 can guide rainwater to drain naturally, and increase the service life of the engine hood on the basis of ensuring structural strength.

[0025] It should be noted that the design of the inclined surface and the guide surface 210 at the top of the main body 100 utilizes the flow characteristics of the fluid. The combination of gravity and the inclined surface and the guide surface 210 creates a driving force for rainwater to flow down naturally. Gravity provides the driving force for rainwater to flow downward, while the inclined surface and the guide surface 210 provide a flow path for rainwater. This design allows rainwater to flow down quickly and smoothly along the inclined surface and the guide surface 210, effectively preventing rainwater from accumulating or remaining on the surface of the hood. Through the special design of the conical structure, the inclined surface, the first protrusion 200 and its guide surface 210, the effect of rainwater flowing down naturally along the inclination and the guide surface 210 due to gravity is achieved, thereby effectively preventing rainwater from remaining and extending the service life of the engine hood.

[0026] Reference Figure 1In some embodiments, the guide surface 210 completely covers the portion of the main body 100 near the edge of the top surface. This means that starting from the edge of the top surface of the hood, the guide surface 210 has begun to play its role, extending all the way to the side and even the bottom of the hood. This design ensures that once rainwater contacts the hood, it can be immediately guided by the guide surface 210 and flow down along the designed path, effectively preventing rainwater from accumulating at the edge of the hood. Secondly, this design also improves the aesthetics and practicality of the hood. Since rainwater can flow down quickly and smoothly, it is not easy to form water droplets or water stains on the surface of the hood, maintaining the overall beauty of the hood. At the same time, it also prevents rainwater from dripping onto the rider or other parts of the motorcycle, thereby improving riding safety and comfort.

[0027] Reference Figure 1 , Figure 2 and Figure 3 The main body 100 is also provided with a second protrusion 300, which is also inclined from the main body 100 toward the outside to form a transition surface 310, and the transition surface 310 is connected to the guide surface 210. The second protrusion 300 is located on both sides of the first protrusion 200 and extends to the edge of the main body 100. The second protrusion 300 is also inclined from the main body 100 toward the outside to form a transition surface 310. This transition surface 310 is connected to the guide surface 210 to ensure that rainwater can flow continuously and smoothly. The second protrusion 300 is located on both sides of the first protrusion 200 and extends to the edge of the main body 100. This design further expands the drainage range of rainwater and enhances the discharge effect of rainwater. The second protrusion 300 cooperates with the first protrusion 200 and its guide surface 210 to form a complete rainwater drainage system. Under the action of gravity, rainwater can flow down this system quickly and smoothly, effectively preventing rainwater from accumulating on the hood.

[0028] Reference Figure 1 , Figure 2 and Figure 3 Furthermore, the main body 100 is also provided with a cylindrical rib 130, which is located at the side of the main body 100. The cylindrical rib 130 is arranged obliquely, and the outer wall of the cylindrical rib 130 is connected to the guide surface 210 or the transition surface 310. The cylindrical rib 130 arranged at the side not only enhances the structural stability of the canopy, but also further optimizes the flow path of rainwater by connecting with the guide surface 210 or the transition surface 310. This design not only improves the discharge efficiency of rainwater, but also makes the entire canopy more beautiful and coordinated in appearance.

[0029] Reference Figure 3 The inner side of the main body 100 is provided with a plurality of guide platforms 140, and the guide platforms 140 are provided with through mounting holes 141 for fixing the oil dipstick. The setting of the guide platforms 140 provides a stable and reliable supporting platform for the installation of the oil dipstick, thereby improving the overall practicality and convenience of the cover.

[0030] Reference Figure 1 and Figure 3 The main body 100 is also provided with a fixing seat 150, which is used to install the clutch operating rod. The fixing seat 150 is cylindrical and arranged obliquely on the side of the main body 100. The outer surface of the fixing seat 150 is connected to the guide surface 210. The fixing seat 150 facilitates the installation of the clutch operating rod and makes the structure of the entire cover more compact and beautiful. At the same time, the connection design between the fixing seat 150 and the guide surface 210 also further enhances the rainwater drainage effect of the cover, effectively preventing the accumulation of rainwater on the cover.

[0031] Reference Figure 3 Furthermore, a plurality of internal reinforcing ribs are arranged on the inner side surface of the main body 100, and the plurality of internal reinforcing ribs are evenly arranged in a criss-cross pattern inside the main body 100 to further enhance the structural strength of the cover.

[0032] Reference Figure 1 , Figure 2 and Figure 3 A fixing rib 120 is arranged around the periphery of the main body 100, and a number of fixing holes 121 are evenly and equidistantly arranged on the fixing rib 120. As a reinforcement structure surrounding the main body 100, the fixing rib 120 can effectively resist external impact and vibration and protect the machine cover from being easily damaged. This design improves the durability of the machine cover and extends its service life. The setting of the fixing holes 121 makes the installation and fixation of the machine cover more convenient and reliable. It not only simplifies the installation process, but also improves the accuracy and stability of the installation, and reduces the risk of the machine cover loosening or falling off due to improper installation.

[0033] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
