Description

Technical Field

[0001] This utility model relates to the technical field of motorcycle frame devices, and in particular to a lightweight motorcycle frame. Background Technology

[0002] Motorcycles are lightweight and agile, allowing them to navigate roads without being affected by traffic congestion, greatly alleviating traffic jams. They are widely used in people's daily lives, with small motorcycles being the most common type suitable for family use. However, small motorcycles have limited cargo capacity in their seat bags, making it difficult to carry many items. This is especially true for people living in mountainous areas, who often use motorcycles for shopping and transporting goods. To increase cargo capacity, people purchase and install motorcycle frames to expand storage space. However, current motorcycle frames on the market lack flexibility and adaptability. A Chinese patent discloses a "lightweight motorcycle frame" that... The application number is "CN201821478999.0". This device is equipped with a tube bending frame and springs. The connecting plate installed on the tube bending frame is rotatably connected to the straight plate, so that the tube bending frame and the upper tube frame can be adjusted and fixed by rotation. At the same time, the installed springs can reduce the vibration of items placed on the upper tube frame when shock absorption is needed. Although the device is fixed by welding, it uses the installed springs to reduce the vibration of items placed on the upper tube frame when shock absorption is needed. However, this device has certain limitations in terms of load-bearing requirements at the rear of the vehicle. Therefore, in order to further improve the practicality of the device, we provide a lightweight motorcycle frame to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a lightweight motorcycle frame. In this lightweight motorcycle frame, the frame is fixedly connected to the rear of the motorcycle via a mounting plate. When the items on the frame are larger than the length and width of the frame, the fixing rod is pulled out, and the extension rod is pulled out. The limiting plate abuts against the opening of the movable hole, and at the same time, the pressure spring is also stretched, which enhances the strength and toughness of the fixing frame, improves the vibration and impact resistance, prevents the fixing from loosening, and also improves the load-bearing capacity of the frame. Then, the fixing rod is inserted into the position where the mounting hole coincides with the mounting hole, and the fixing rod is fixed to the mounting hole using a fixing sleeve. Then, the connecting block is rotated so that the movable plate and the fixing frame are in the horizontal direction. This improves the limitations of the traditional fixed rear frame, not only enhancing the flexibility and adaptability of the structure, but also improving the overall robustness and ease of operation, making it more suitable for various usage scenarios, different sizes of rear frames, or cargo carrying needs.

[0004] This utility model also provides a lightweight motorcycle frame, comprising: a fixed frame, a reinforcing rib, an extension rod, a connecting rod, and a movable plate. The fixed frame is made of aluminum alloy, and a movable hole is provided inside the fixed frame. A pressure spring is provided inside the movable hole. The fixed frame and the extension rod are movably connected. A movable groove is provided on the outer surface of the fixed frame. A connecting block is rotatably connected inside the movable groove. A movable plate is fixedly connected to the outer surface of the connecting block. A limit plate is fixedly connected to one end of the extension rod, and the surface of the limit plate is fixedly connected to one end of the pressure spring.

[0005] According to the present invention, a lightweight motorcycle frame is provided, wherein the fixing frame is shaped like a square tube and the extension rod is shaped like a round tube. This allows the overall frame to reduce weight while ensuring rigidity.

[0006] According to the present invention, a lightweight motorcycle frame has a mounting plate fixedly connected to its inner side, and the mounting plate has threaded holes inside. This is used for fixing to the rear of the motorcycle.

[0007] According to the present invention, a lightweight motorcycle frame is provided, wherein the extension rod is U-shaped, and a reflective sticker is fixedly connected to the outer surface of the U-shaped surface of the extension rod. This is used to ensure the safety of vehicles behind when driving at night.

[0008] According to the present invention, a lightweight motorcycle frame has mounting holes on the surface of the extension rod, and a mounting hole is provided at the end of the fixing bracket away from the mounting plate. These are used to fix the frame to the rear of the motorcycle and the extension rod, respectively.

[0009] According to the present invention, a lightweight motorcycle frame includes a fixing rod installed in the mounting hole of the fixing bracket. A fixing sleeve is fitted onto one end of the fixing rod, and the fixing sleeve is made of rubber. This serves to fix the fixing rod to the mounting hole in the extension rod.

[0010] According to the lightweight motorcycle frame of this utility model, the diameter of the movable hole is the same as the diameter of the limiting plate, and the diameter of the limiting plate is larger than the diameter of the extension rod. This facilitates the limiting plate to compress and stretch the pressure spring.

[0011] According to the present invention, a lightweight motorcycle frame has two ends of a reinforcing rib that are fixedly connected to a fixed frame and a connecting rod, respectively, with the connecting rod perpendicular to the fixed frame. This design allows the overall frame structure to maintain its strength while reducing its overall weight.

[0012] Beneficial effects: This lightweight motorcycle frame is fixedly connected to the rear of the motorcycle via a mounting plate. When the items on the frame are larger than the frame's length and width, the fixing rod is pulled out, and the extension rod is pulled out. The limiting plate abuts against the opening of the movable hole, and at the same time, the pressure spring is also stretched, enhancing the strength and toughness of the fixing frame, improving its vibration and impact resistance, preventing loosening, and also increasing the frame's load-bearing capacity. The fixing rod is then inserted into the mounting hole, and the fixing sleeve is used to fix the fixing rod to the mounting hole. Then, the connecting block is rotated so that the movable plate and the fixing frame are in a horizontal position. This improves the limitations of traditional fixed rear racks, not only enhancing the flexibility and adaptability of the structure, but also improving the overall robustness and ease of operation, making it more suitable for various usage scenarios, different sizes of rear racks, or cargo carrying needs.

[0021] Reference Figure 1-4This utility model discloses a lightweight motorcycle frame, comprising: a fixing frame 1, a reinforcing rib 2, an extension rod 3, a connecting rod 4, and a movable plate 5, for assembling into a complete frame. The fixing frame 1 is made of aluminum alloy to achieve a lightweight yet sturdy and durable overall frame. The fixing frame 1 has an internal movable hole 101 to further reduce the overall weight of the frame. A pressure spring 8 is installed inside the movable hole 101 to enhance the overall durability and toughness of the fixing frame 1, preventing excessive weight reduction from causing safety hazards. The fixing frame 1 and the extension rod 3... The frame is designed as a movable connection to extend the length of the frame. The outer surface of the fixed frame 1 has a movable groove 102 to facilitate the rotation of the connecting block 6. The connecting block 6 is rotatably connected inside the movable groove 102 to fix and support the movable plate 5. The outer surface of the connecting block 6 is fixedly connected to the movable plate 5 to extend the width of the frame. One end of the extension rod 3 is fixedly connected to a limit plate 31 to prevent the extension rod 3 from being completely separated from the fixed frame 1 after being stretched. The surface of the limit plate 31 is fixedly connected to one end of the pressure spring 8 to facilitate the extension rod 3 to retract and stretch with the fixed frame 1.

[0022] The mounting bracket 1 is shaped like a square tube, and the extension rod 3 is shaped like a round tube, which ensures the overall frame is rigid while reducing weight. A mounting plate 7 is fixedly connected to the inner side of the mounting bracket 1. The mounting plate 7 has threaded holes inside for fixing to the rear of the motorcycle. The extension rod 3 is U-shaped, and reflective material 9 is fixedly connected to the outer surface of the U-shaped surface of the extension rod 3 to ensure visibility to vehicles behind during nighttime driving. Mounting holes 10 are formed on the surface of the extension rod 3. A mounting hole one is formed at the end of the mounting bracket 1 away from the mounting plate 7 for fixing to the rear of the motorcycle and the extension rod 3 respectively. A fixing rod 11 is installed inside the mounting hole one of the mounting bracket 1. One end of the fixing rod 11 is fitted with a fixing sleeve 12, which is made of rubber. The fixing sleeve 12 is used to fix the fixing rod 11 to the mounting hole in the extension rod 3, so as to prevent the extension rod 3 from loosely separating from the fixing frame 1. The diameter of the movable hole 101 is the same as the diameter of the limiting plate 31. The diameter of the limiting plate 31 is larger than the diameter of the extension rod 3, so that the limiting plate 31 can compress and stretch the pressure spring 8 and ensure that the extension rod 3 is stored and extended in the fixing frame 1. The two ends of the reinforcing rib 2 are fixedly connected to the fixing frame 1 and the connecting rod 4 respectively. The connecting rod 4 is perpendicular to the fixing frame 1, so that the overall structure of the frame can maintain the overall strength while reducing the weight of the overall structure.

[0023] Working principle: When using this lightweight motorcycle frame, it is first fixedly connected to the rear of the motorcycle via the mounting plate 7. When the items on the frame are larger than the length and width of the frame, the fixing rod 11 is pulled out and the extension rod 3 is pulled out. The limiting plate 31 abuts against the opening of the movable hole 101, and the pressure spring 8 is also stretched, which enhances the toughness and strength of the fixed frame 1. Then, the fixing rod 11 is inserted into the mounting hole 10 and the mounting hole 10 is aligned. The fixing sleeve 12 is used to fix the fixing rod 11 to the mounting hole 10. Then, the connecting block 6 is rotated so that the movable plate 5 and the fixed frame 1 are in the horizontal direction.
