Description

Technical Field

[0001] This utility model relates to the field of motorcycle component technology, and more particularly to left and right side cover components for motorcycles. Background Technology

[0002] Motorcycle side covers are plastic or metal shells that cover both sides of the frame. They mainly protect internal components such as the engine, air filter, and battery from dust, water splashes, and impacts; optimize airflow around the vehicle, reduce wind resistance, and improve high-speed stability.

[0003] Many motorcycle side cover assemblies suffer from insufficient sealing performance, allowing rainwater, dust, and even water vapor to easily enter the motorcycle through gaps. This affects driving performance and the stability of the electrical system, increases the failure rate, and causes unnecessary trouble for the rider. Secondly, the disassembly and assembly process of existing motorcycle side cover assemblies is complex. Many users have reported that installing or replacing side covers requires a significant amount of time, patience, and skill, which not only increases maintenance costs but also greatly reduces the convenience of motorcycle maintenance. In particular, it may delay repair time in emergency situations, affecting the user's ability to handle issues safely and promptly. Furthermore, motorcycles are often driven under various operating conditions, and the vibrations and impacts from these external environments can easily damage the side cover assemblies. Especially at high speeds, the side cover area is susceptible to strong vibrations, leading to damage to some connection parts or seals, shortening the lifespan of the side cover, and increasing the frequency and cost of motorcycle maintenance. Therefore, we propose a new side cover assembly for motorcycles. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. Many motorcycle side cover assemblies have insufficient sealing performance, allowing rainwater, dust, and even water vapor to easily enter the motorcycle through gaps, affecting driving performance and the stability of the electrical system, increasing the failure rate, and causing unnecessary inconvenience to the driver. Secondly, the disassembly and assembly process of existing motorcycle side cover assemblies is complex. Many users have reported that installing or replacing side covers requires a significant amount of time, patience, and skill, which not only increases maintenance costs but also greatly reduces the convenience of motorcycle maintenance. This can delay repairs, especially in emergencies, affecting the user's ability to handle situations safely and promptly. Furthermore, motorcycles are frequently driven under various operating conditions, and the vibrations and impacts from these external environments can easily damage the side cover assemblies. Especially at high speeds, the side cover area is susceptible to strong vibrations, leading to damage to some connecting parts or seals, shortening the lifespan of the side cover, and increasing the frequency and cost of motorcycle maintenance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: The left and right side cover assemblies for motorcycles include a side cover body with ventilation holes. The side cover body has a streamlined asymmetrical curved surface. The front end of the side cover body is narrow and fits the frame, while the rear end gradually widens to cover components such as the engine or air filter. A guide rail is installed on the inner wall of the side cover body, and several elastic buckles are installed on the edge of the side cover body.

[0006] Furthermore, two guide rails are provided and symmetrically installed on both sides of the inner wall of the side cover body, and the guide rails that match the guide rails are installed on the motorcycle frame.

[0007] Furthermore, several of the elastic buckles are installed above and below the edge of the side cover body. The head of the elastic buckle has a double barb structure, and the elastic buckle matches the trapezoidal groove opened on the motorcycle frame.

[0008] Furthermore, a honeycomb matrix is ​​provided on the inner wall of the side cover body, the cell diameter of the honeycomb matrix is ​​arranged in a gradually changing pattern of 5mm-8mm, and the honeycomb cells are filled with silicone damping material.

[0009] Furthermore, the side cover body has a wedge-shaped air guide cavity on the contact surface with the vehicle frame, and the cavity opening of the air guide cavity faces the driving direction.

[0010] Furthermore, a V-shaped water guide groove is provided around the periphery of the side cover body, and the bottom of the V-shaped water guide groove is connected to a hidden drain pipe, which leads directly to the bottom of the side cover body.

[0011] Furthermore, a magnetic EPDM strip is embedded in the V-shaped water guide channel, and the magnetic EPDM strip forms a magnetic seal with the galvanized steel strip on the motorcycle frame.

[0012] Furthermore, a one-way silicone valve is provided at the outlet of the drain pipe at the bottom of the V-shaped water guide channel.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The side cover is embedded with a magnetic sealing strip, which forms a strong magnetic attraction with the galvanized steel strip of the frame to ensure a tight fit and greatly improve waterproof and dustproof capabilities.

[0022] Example 1 like Figure 1-4 As shown, this utility model provides a technical solution: a left and right side cover assembly for a motorcycle, including a side cover body 1, on which ventilation holes 101 are provided. The side cover body 1 has a streamlined asymmetrical curved surface. The front end of the side cover body 1 is narrow and fits the frame, while the rear end gradually widens to cover components such as the engine or air filter. The streamlined asymmetrical curved surface optimizes aerodynamics and reduces high-speed wind resistance while ensuring strength. A guide rail 102 is installed on the inner wall of the side cover body 1, and several elastic buckles 103 are installed on the edge of the side cover body 1. The buckles and guide rails are integrated into one design, avoiding the cumbersome steps of traditional screw fixing and reducing maintenance costs.

[0023] Example 2 like Figure 1-4 As shown, there are two guide rails 102, which are symmetrically installed on both sides of the inner wall of the side cover body 1. The guide rails matched by the guide rails 102 are installed on the motorcycle frame. Several elastic buckles 103 are installed above and below the edge of the side cover body 1. The head of the elastic buckle 103 is a double barb structure. The elastic buckle 103 matches the trapezoidal groove opened on the motorcycle frame. The elastic buckle 103 and the guide rail 102 are connected as a whole by internal reinforcing ribs. The end of the guide rail 102 is provided with a limiting boss to prevent excessive insertion. A honeycomb matrix 104 is provided on the inner wall of the side cover body 1. The cell diameter of the honeycomb matrix 104 is arranged in a gradient of 5mm-8mm. The honeycomb of the honeycomb matrix 104 is filled with silicone damping material. A wedge-shaped air guide cavity is provided on the contact surface between the side cover body 1 and the frame. The opening of the air guide cavity faces the driving direction. The honeycomb matrix 104 and the air guide cavity are integrally formed by 3D printing process. A resonant perforation is provided at the 1.2mm thick wall of the guide cavity. A V-shaped water guide groove 105 is provided around the perimeter of the side cover body 1. The bottom of the V-shaped water guide groove 105 is connected to a hidden drain pipe, and the hidden drain pipe goes straight to the bottom of the side cover body 1. A magnetic EPDM strip 106 is embedded in the V-shaped water guide groove 105. The magnetic EPDM strip 106 forms a magnetic seal with the galvanized steel strip on the motorcycle frame. The magnetic EPDM strip 106 and the V-shaped water guide groove 105 are formed by co-extrusion process. A one-way silicone valve is provided at the drain pipe outlet at the bottom of the V-shaped water guide groove 105. The one-way silicone valve prevents the airflow from drawing sewage back during high-speed driving.

[0024] The working process of this utility model is as follows: When using the left and right side cover components for motorcycles, the motorcycle left and right side cover components are first installed by precisely connecting the guide rail 102 with the frame guide rail to ensure that the side cover body 1 slides into place along the predetermined path. When the side cover moves to the position of the limiting boss, the double barb structure of the elastic buckle 103 automatically engages with the trapezoidal groove of the frame to form a self-locking fixation. The whole process does not require tools and can be completed by simply pressing. A firm installation is achieved within 10 seconds. After the side cover is closed, the magnetic EPDM strip 106 adheres tightly to the galvanized steel strip of the frame through magnetic attraction, forming a dynamic seal. When rainwater or dust comes into contact with the edge of the side cover, it collects along the V-shaped water guide groove 105 and is quickly discharged through the concealed drain pipe. The one-way silicone valve at the outlet of the drain pipe prevents backflow of airflow during driving, ensuring stable waterproof performance. When engine vibration is transmitted to the side cover, the silicone damping material in the honeycomb matrix 104 absorbs high-frequency vibration. At the same time, the wedge-shaped air guide cavity uses driving wind pressure to form an air cushion to buffer and reduce resonance noise. The resonant perforation of the guide cavity optimizes the airflow path and assists in engine heat dissipation, while the ventilation hole 101 further enhances aerodynamic efficiency.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
