Description

Technical Field

[0001] This utility model relates to the field of electric bicycle rear fork technology, and in particular to a removable electric bicycle rear fork structure. Background Technology

[0002] As we all know, electric bicycles are a popular and frequently used mode of transportation, making them a top choice for getting around. Especially in short-distance transport scenarios, electric bicycles play a crucial role, navigating busy backstreets and alleys inaccessible to motor vehicles, or bustling markets. For easy disassembly, pre-designed breakpoints (such as threaded connections, snap-fit ​​mechanisms, or hinges) allow the fork to separate from the frame, facilitating maintenance, transport, or modification. However, existing breakpoint-type rear forks are structurally complex, cannot quickly separate from the frame, and cannot be used with shock absorbers to improve shock absorption. Utility Model Content

[0003] To overcome the technical defects of the existing technology, this utility model provides a removable electric bicycle rear fork structure, which is easy and quick to disassemble and can be used with a shock absorber to achieve a better shock absorption effect.

[0005] It also includes a retaining block and a plug-in block that cooperate with each other. The retaining block is welded to the frame and has a plug-in groove for the plug-in block to be inserted into. The mating end of the mounting frame is provided with a connecting pipe that is arranged laterally. The plug-in block has a pair of mounting seats. A socket for the connecting pipe to be inserted laterally is formed between the pair of mounting seats. The connecting pipe and the mounting seats pass through the central axis of the connecting pipe. The connecting pipe rotates along the central axis. The two ends of the central axis are provided with limit caps. The limit caps are welded to the central axis. The retaining block and the plug-in block are provided with vertically installed positioning bolts.

[0006] Preferably, the central shaft, retaining block, plug-in block, and mounting base are all made of high-strength materials.

[0007] Preferably, a wear-resistant gasket is provided between the mounting base and the end of the connecting pipe.

[0008] Preferably, the reinforcing rod is provided with a connecting block, and the connecting block is hinged to a spring damping rod, and the other end of the spring damping rod is provided with a hinge block, and the frame is provided with a positioning block that is bolted to the hinge block.

[0009] Preferably, the left and right forks are equipped with foot pedals.

[0010] Preferably, the left fork and the right fork are provided with multiple retaining blocks.

[0011] The beneficial effects of this utility model are as follows: by installing the connecting tube at the front end of the mounting frame on the central axis into the socket formed between a pair of mounting seats, the connecting tube can rotate along the central axis. The mounting seats are set on the plug-in block, and a retaining block is welded on the frame. The plug-in block is inserted into the plug-in slot. Then, by using vertically installed positioning bolts on the retaining block and the plug-in block, the rear fork mechanism is fixed to the vehicle body. The positioning bolts can be removed for quick disassembly and assembly. The structure is simple, and the rear fork mechanism can rotate, which, when used with the shock absorber, provides a better shock absorption effect. Compared with the fixed transmission type, it has a better shock absorption effect and is also easy to disassemble. Attached Figure Description

However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.

[0019] like Figures 1 to 4 As shown, this embodiment provides a removable electric bicycle rear fork structure, including a mounting frame 1, on which a left fork 2 and a right fork 3 are provided, and a reinforcing rod 4 is provided between the left fork 2 and the right fork 3 on the side close to the mounting frame 1.

[0020] It also includes a retaining block 5 and a plug-in block 6 that cooperate with each other. The retaining block 5 is welded to the frame and has a plug-in groove 7 for the plug-in block 6 to be inserted into. The mating end of the mounting frame 1 is provided with a connecting pipe 8 arranged horizontally. The plug-in block 6 is provided with a pair of mounting seats 9. A socket for the connecting pipe 8 to be inserted horizontally is formed between the pair of mounting seats 9. The connecting pipe 8 and the mounting seat 9 pass through the central axis 10 of the connecting pipe 8. The connecting pipe 8 rotates along the central axis 10. The two ends of the central axis 10 are provided with limiting covers 11. The limiting covers are welded to the central axis 10. The retaining block 5 and the plug-in block 6 are provided with vertically installed positioning bolts 12. The connecting tube 8 at the front end of the mounting frame is installed in the socket formed between a pair of mounting seats 9 on the central shaft 10, allowing the connecting tube 8 to rotate along the central shaft 10. The mounting seats 9 are set on the plug block 6. A retaining block 5 is welded to the frame, and the plug block 6 is inserted into the plug groove 7. Then, the rear fork mechanism is fixed to the frame by vertically installed positioning bolts 12 on the retaining block 5 and the plug block 6. The positioning bolts 12 can be removed for quick disassembly and assembly. The structure is simple, and the rear fork mechanism can rotate, which, when used with the shock absorber, provides a better shock absorption effect. Compared with the fixed drive type, it has a better shock absorption effect and is also easy to disassemble.

[0021] The central shaft, retaining block 5, plug-in block 6, and mounting base 9 are all made of high-strength materials, which makes them less prone to damage and less likely to deform at the hinge rotation points.

[0023] Therefore, the reinforcing rod 4 is provided with a connecting block 14, and the connecting block 14 is hinged to a spring damping rod 15. The other end of the spring damping rod 15 is provided with a hinge block 16. The frame is provided with a positioning block 17 that is bolted to the hinge block 16. In this way, the mounting frame and the frame are provided with a spring damping rod 15, and the connection is made by using the spring damping rod, thereby improving the connection strength and ensuring a good shock absorption effect.

[0024] The left fork 2 and right fork 3 are equipped with footrests 18 for convenient foot placement. The left fork 2 and right fork 3 are also equipped with multiple retaining blocks 5 for easy fixation to the rear seat frame.

[0025] Among the aforementioned components, those subjected to high stress are all made of high-strength materials, exhibiting strong resistance to deformation and high load-bearing capacity.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0027] Working principle: The connecting tube 8 at the front end of the mounting frame is installed in the socket formed between a pair of mounting seats 9 on the central shaft 10, allowing the connecting tube 8 to rotate along the central shaft 10. The mounting seats 9 are set on the plug block 6. The frame has a retaining block 5 welded on it, and the plug block 6 is inserted into the plug groove 7. The rear fork mechanism is fixed to the frame by vertically installed positioning bolts 12 on the retaining block 5 and the plug block 6. The positioning bolts 12 can be removed for easy disassembly. The rear fork mechanism can rotate, which, when used with the shock absorber, provides a better shock absorption effect. Compared with the fixed type of transmission, it has a better shock absorption effect and is also easier to disassemble.
