[0002] With the increase in motorcycle engine displacement, there is an urgent need to improve the heat dissipation performance of motorcycles.

[0003] In related technologies, motorcycles are generally equipped with radiators, which are used to capture the airflow during driving and cool the high-temperature components on the motorcycle.

[0004] However, the radiators in the relevant technologies suffer from low airflow and limited cooling efficiency. Summary of the Invention

[0005] In view of the problems of low air intake and limited cooling efficiency of radiators in related technologies, this application provides a protective cover device, a radiator assembly and a motorcycle.

[0006] On one hand, this application provides a protective cover device for covering and installing on a motorcycle radiator device. The protective cover device includes a protective cover body and at least two wing plates. The protective cover body has an air inlet. The wing plates are connected to the protective cover body and disposed at the air inlet. The wing plates are arranged at intervals along the driving direction of the motorcycle, and a guide groove is formed between two adjacent wing plates. The extension dimension of each wing plate in the width direction of the motorcycle increases from the front to the rear in the driving direction.

[0007] In one embodiment, the shielding device includes at least three wing plates, and the difference in the extension dimension between any two adjacent wing plates is the same.

[0008] In one embodiment, the wing is angled toward the front of the motorcycle.

[0009] In one embodiment, the angle between the surface of the wing and the direction of travel is 0°-90°.

[0010] In one embodiment, a reinforcing rib is connected between two adjacent flanges.

[0011] In one embodiment, the shield device further includes a sealing strip disposed on the side surface of the shield body facing the radiator device, and the sealing strip is used to seal against the core of the radiator device.

[0012] In one embodiment, the protective cover body includes a front end structure and a rear end structure. The front end structure corresponds to the front end of the driving direction, and the rear end structure corresponds to the rear end of the driving direction. The sealing strip is connected to the rear end structure, and the sealing strip abuts against the radiator device.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0028] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0029] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0030] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited.

[0032] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0033] See Figures 1 to 6 This application provides a protective cover device 100, which is used to cover and install on a motorcycle radiator device 200. Specifically, the protective cover device 100 is used to cover the air intake side of the motorcycle radiator device 200. The protective cover device 100 is used to guide and converge the airflow entering the radiator device 200, thereby improving the air intake volume and cooling efficiency of the radiator.

[0034] It should be noted that the radiator device 200 is generally located on the right side of the rear wheel of the motorcycle, and the air intake side of the radiator device 200 corresponds to the side of the motorcycle in the width direction. More specifically, during riding, the airflow flows from the side of the motorcycle through the shield device 100, and then through the core of the radiator device 200 to complete heat exchange.

[0035] More specifically, for water-cooled scooter motorcycles, the radiator assembly 10 of the engine water-cooling system is typically located in the cavity space between the rear wheel and the side cover of the chassis. Due to the limitations of the overall vehicle layout, this cavity space is usually quite narrow, and airflow is prone to turbulence and uneven diffusion after entering the cavity, resulting in low effective utilization of the radiator core in related technologies. The shield device 100 of this application is designed specifically for these spatial characteristics. By optimizing the structure of the shield device 100, the air intake volume is increased, thereby improving both air intake volume and cooling efficiency within a limited space.

[0036] Please see Figure 2 The protective cover device 100 provided in this application may include a protective cover body 110 and at least two wing plates 120. The protective cover body 110 has an air inlet, and the wing plates 120 are arranged at intervals along the motorcycle's travel direction X, with a guide groove 121 formed between two adjacent wing plates 120. The extension dimension of each wing plate 120 in the width direction Y of the motorcycle increases from the front to the rear in the travel direction X.

[0037] It should be noted that, Figure 1 This can be considered a front view of the shield device 100 mounted on the radiator device 200 and located on the side of the vehicle body. The aforementioned front side refers to the side closer to the front of the vehicle in the direction of travel X, and the aforementioned rear side refers to the side closer to the rear of the vehicle in the direction of travel.

[0038] Optionally, the shield body 110 can be a plate-shaped shell structure adapted to the shape of the radiator device 200. The air inlet can be opened in the middle of the shield body 110, and the air inlet is set directly opposite the core air inlet surface of the radiator device 200.

[0039] The aforementioned shield device 100 of this application, through the configuration of each wing 120 corresponding to the extension dimension in the width direction Y of the motorcycle and arranged in a progressively increasing manner from the front to the rear in the driving direction X, helps to form a stepped airflow guiding structure with a lower front and higher rear on the air intake side of the shield device 100. This allows it to capture more upstream airflow during motorcycle operation, guiding the airflow to fully enter the core of the radiator device 200, thereby improving airflow volume and cooling efficiency. It is also worth noting that the aforementioned shield device 100 of this application helps to increase airflow volume without increasing the size of the radiator device 200, thus improving adaptability to the narrow spaces of the vehicle layout.

[0040] Optionally, the number of wing plates 120 can be configured as, but is not limited to, 2, 3, 4, 5, 6, 8, and 10, etc. No specific restrictions are imposed in this application, and users can set it according to actual design needs.

[0041] In some embodiments, at least two mounting ear structures (not shown) may be evenly provided on the circumferential edge of the shield body 110. The mounting ear structures may be integrally formed with the shield body 110 and are used for mutual assembly with the heat sink device 200, thereby improving assembly ease. Of course, in other embodiments, the shield body 110 and the heat sink device 200 may also be assembled by means of snap-fit ​​or other methods, but not limited to snap-fit.

[0042] In some embodiments, the shield device 100 includes at least three wing plates 120, and the difference in the extension dimension between any two adjacent wing plates 120 is the same, that is, the extension dimension of each wing plate 120 increases linearly and equally from the front to the rear along the driving direction X, so that the flow cross section of the guide groove 121 changes uniformly along the airflow direction, which helps to make the airflow smoother and reduce local turbulence and wind resistance.

[0043] For example, in the design of the height parameters of the wing 120, in one specific numerical embodiment, in the direction of travel X, at the rearmost end (e.g. Figure 2 The first wingplate 120 (shown as the leftmost one) has a height of 20mm, the second wingplate 120 has a height of 17mm, the third wingplate 120 has a height of 14mm, and the fourth wingplate 120 has a height of 11mm. It is located at the very front (e.g., Figure 2 The height of the fifth wingplate 120 (shown as the rightmost one) is 8mm, and the height difference between adjacent wingplates 120 is constant at 3mm.

[0044] It is understood that in other embodiments, the height of the wing 120 may also decrease non-linearly, for example, from rear to front along the driving direction X. Figure 2 As shown (corresponding to left to right), the height difference between adjacent wing plates 120 gradually decreases, that is, the height of adjacent wing plates 120 at the rear end changes rapidly, while the height of adjacent wing plates 120 at the front end changes slowly. Users can set this according to actual design needs.

[0045] Please see Figure 2 In some embodiments, the wing 120 is tilted toward the front of the motorcycle. This tilted design allows the wing 120 to smoothly guide the oncoming airflow, reducing the drag loss when the airflow hits the front of the wing 120. At the same time, it guides the airflow toward the core of the radiator device 200, improving the air intake and cooling efficiency.

[0046] In some embodiments, the outer edge of the wing 120 is provided with a rounded transition, which helps to reduce airflow separation when the airflow passes over the top of the wing 120, thereby reducing wind noise and local vortex loss. It should be noted that the outer edge of the wing 120 refers to the edge on the side away from the radiator device 200 in the width direction of the vehicle body, which is the edge that first comes into contact with the oncoming airflow in the driving direction X.

[0047] In some embodiments, the angle between the surface of the wing plate 120 and the driving direction X is 0°-90°. Within this angle range, the overall thickness of the shield device 100 can be reduced by controlling the deviation angle, while ensuring good air guiding effect and adapting to the installation space of the vehicle.

[0048] Optionally, the angle between the surface of the wing plate 120 and the travel direction X can be, but is not limited to, 0°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, 90°, etc.

[0049] Please see Figures 1 to 6 In any of the embodiments, a reinforcing rib 130 is connected between two adjacent wing plates 120. The two ends of the reinforcing rib 130 are respectively connected to the opposite sidewalls of the two adjacent wing plates 120. This can improve the overall structural strength of the wing plate 120, prevent the wing plate 120 from deforming under the impact of high-speed airflow, and also assist in rectifying the airflow in the guide groove 121.

[0050] Understandably, the stiffener 130 has various arrangements to accommodate different strength and flow requirements.

[0051] In one implementation, such as Figure 1 As shown, each reinforcing rib 130 is arranged obliquely and evenly along the plane of the shield body 110. It should be noted that the plane of the shield body 110 refers to the direction along a plane perpendicular to the width direction Y of the vehicle body, in which the reinforcing ribs 130 are arranged obliquely and evenly.

[0052] In some other embodiments, each guide channel 121 may be provided with at least two reinforcing ribs 130, such as two or three.

[0053] Please see Figure 2 , Figure 4 , Figure 5 and Figure 6In some embodiments, the shield device 100 may further include a sealing strip 140, which is disposed on the side surface of the shield body 110 facing the radiator device 200. The sealing strip 140 is used to seal against the core of the radiator device 200. Specifically, when the shield device 100 is closed on the radiator device 200, the sealing strip 140 seals against the end face of the core of the radiator device 200. This reduces cold air leakage between the shield body 110 and the radiator device 200, ensuring that the cold air after heat exchange through the core of the radiator device 200 can be used to cool the high-temperature components of the motorcycle, thereby improving cooling efficiency.

[0054] Please see Figure 2 In some embodiments, the protective cover body 110 includes a front end structure 112 and a rear end structure 113. The front end structure 112 corresponds to the front end in the driving direction X, and the rear end structure 113 corresponds to the rear end in the driving direction X. A sealing strip 140 is connected to the rear end structure 113. Specifically, the sealing strip 140 is connected to the inner surface of the rear end structure 113 and extends along the length of the contour of the rear end structure 113. Figure 6 As shown, when the radiator assembly 200 and the shield assembly 100 are assembled together, the rear structure 113 is tightly sealed to the rear end face of the radiator assembly 200 core by the sealing strip 140. A guide gap 1121 is provided between the radiator assembly 200 and the front structure 112. Specifically, a guide gap 1121 is reserved between the front end face of the radiator assembly 200 core and the front structure 112. This structure allows the airflow entering from the front guide groove 121 to first accumulate within the cavity, and finally diffuse through the guide gap 1121 to the front region of the radiator assembly 200 core, thus increasing the airflow volume at the front of the radiator assembly 200 core and improving cooling efficiency.

[0055] It is understood that the arrangement of the sealing strip 140 is not limited to the rear structure 113. In another embodiment, the sealing strip 140 is continuously arranged along the rear end and upper and lower edges of the shield body 110 to form a U-shaped sealing structure, with a guide gap 1121 reserved only at the front end. The U-shaped sealing structure can further reduce airflow leakage from both sides of the shield body 110, improve the overall sealing effect, and force more airflow to diffuse from the guide gap 1121 at the front end to the front of the core, further increasing the air intake at the front of the core.

[0056] In some embodiments, the wing plate 120 and the shield body 110 can be integrally formed, which helps to improve the overall structure, reduce assembly steps, and ensure the positional accuracy and structural strength of the wing plate 120.

[0057] Optionally, the one-piece molding method may include, but is not limited to, one-piece injection molding.

[0058] See Figure 6 According to another aspect of this application, a radiator assembly 10 is also provided. The radiator assembly 10 may include the aforementioned protective cover device 100, and may further include a radiator device 200. The protective cover device 100 covers and is mounted on the radiator device 200, specifically, the protective cover device 100 covers and is mounted on the air inlet side end face of the radiator device 200. Optionally, the protective cover device 100 and the radiator device 200 may be fixedly assembled by, but not limited to, snap-fit ​​fasteners or other fasteners.

[0059] Optionally, the radiator assembly 200 may include, but is not limited to, a cooling fan assembly (not shown), which can adjust its speed according to the engine coolant temperature signal to achieve intelligent adjustment of heat dissipation power.

[0060] Optionally, the shield device 100 and the cooling fan assembly can be located on opposite sides of the core of the radiator device 200, forming a complete airflow channel. Driving air enters from the shield device 100 side, undergoes heat exchange within the core, and is then drawn out by the fan from the other side. The stepped wing plates 120 of the shield device 100 enhance the airflow capture capability and uniformity on the intake side, while the fan provides forced draft power. Working together, the fan provides forced cooling during idling and low-speed driving, while the driving air provides natural cooling during medium- and high-speed driving, achieving efficient cooling under all operating conditions.

[0061] According to another aspect of this application, this application also provides a motorcycle that may include the radiator assembly 10 described above.

[0062] Optionally, the radiator assembly 10 may be installed on the side of the rear wheel of the motorcycle, so as to correspond to the cooling circuit of the engine water cooling system and to cool the circulating coolant, while also taking into account the heat dissipation and cooling of the magneto chamber.

[0063] Optionally, the motorcycle provided in this application can be a scooter. The radiator assembly 10 is fixed to the mounting point on the right side of the rear wheel of the frame via a mounting bracket.

[0064] The working principle of the radiator assembly 10 of the motorcycle in this application is as follows:

[0065] When the motorcycle moves forward, the oncoming wind first comes into contact with the air intake side of the shield device 100. Since the extension dimension of each wing plate 120 in the width direction Y of the motorcycle is arranged to increase from the front to the rear in the driving direction X, the higher wing plate 120 on the upstream side can capture more incoming air. The airflow flows backward along the guide groove 121 and enters the air intake.

[0066] After the airflow enters the interior of the shroud 100, the rear end of the radiator assembly 10 can be sealed by the sealing strip 140 to prevent leakage and accumulation inside the cavity. Finally, the airflow diffuses through the guide gap 1121 at the front end of the radiator assembly 10 towards the front of the core of the radiator device 200, allowing the airflow to flow more evenly across the entire core of the radiator device 200 and exchange heat. This effectively increases the radiator's airflow and cooling efficiency without increasing the size of the radiator and fan, while simultaneously reducing the engine coolant temperature and the operating temperature of the magneto chamber. It is also worth noting that the sealing strip 140 not only guides the airflow through the guide gap 1121 but also helps prevent the leakage of cold air after heat exchange, further improving cooling efficiency.

[0067] The radiator assembly 10 and the motorcycle described in this application are configured such that the extension dimensions of each wing 120 in the width direction Y of the motorcycle increase from the front to the rear in the driving direction X. This helps to form a stepped airflow structure with a lower front and higher rear on the air intake side of the shroud device 100. As a result, more upstream air can be captured during the motorcycle's operation, and the airflow can be guided to fully enter the core of the radiator device 200, thereby improving the air intake volume and cooling efficiency.

[0068] Please see Figure 7 and Figure 8 To verify the technical effect of the radiator assembly 10 described in this application on a motorcycle, a comparative test was conducted using CFD fluid simulation experiments. The test subjects were a motorcycle equipped with the shield device 100 of this application and a motorcycle with a conventional radiator shield in related technologies. The test conditions covered four typical driving scenarios: idle speed, low speed, medium speed, and high speed. Figure 7 The image shows the test results for the motorcycle group in this application during CFD fluid simulation testing. Figure 8 The figure shows the test results for the motorcycle group in the CFD fluid simulation test of this application.

[0069] For example, during the experiment, a three-dimensional fluid model of the core of the shield device 100 and the radiator device 200 can be established. The incoming air velocity can be set to 30km / h, 60km / h, 90km / h, and 120km / h, the ambient temperature can be 25℃, and the coolant inlet temperature can be 90℃. The air intake of the radiator device 200 can be simulated and calculated.

[0070] Simulation results show that, under various wind speed conditions, the air intake of the shield device 100 of this application is significantly improved compared to the radiator shield of a conventional motorcycle. This verifies that the shield device 100, radiator assembly 10 and motorcycle provided in this application help to improve air intake and cooling efficiency.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
