[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-4 As shown, the front fork of the electric bicycle includes a front fork connecting plate 1. Both sides of the surface of the front fork connecting plate 1 are provided with connecting through holes 2. A connecting pipe 3 is provided inside the connecting through hole 2, and a fixing ring 4 is fixed to the middle of the surface of the connecting pipe 3. When the first front fork rod 6 and the second front fork rod 7 are installed on the connecting pipe 3, the fixing ring 4 can also block and limit the first front fork rod 6 and the second front fork rod 7. The diameter of the fixing ring 4 is smaller than the diameter of the first front fork rod 6 and the second front fork rod 7. In this embodiment, when the oil overflow port 11 discharges the lubricating oil into the When the surface of the fixing ring 4 is fixed, it is convenient for the lubricating oil to enter the inner wall of the first front fork rod 6 and the second front fork rod 7, thereby achieving the purpose of lubrication and facilitating the disassembly operation of the front fork. External threads 5 are provided on the upper and lower sides of the surface of the connecting pipe 3. The first front fork rod 6 and the second front fork rod 7 are provided on the upper and lower sides of the connecting pipe 3 respectively. One side of the inner wall of the first front fork rod 6 and the second front fork rod 7 is provided with an internal thread 8. The upper and lower sides of the connecting pipe 3 respectively extend to the interior of the first front fork rod 6 and the second front fork rod 7 and pass through the external thread 5 and the internal thread 8 is threadedly connected, and a limiting ring 9 is fixed on the surface of the first front fork rod 6 and the second front fork rod 7. The diameter of the first front fork rod 6 and the second front fork rod 7 is the same as the inner diameter of the connecting through hole 2, and the first front fork rod 6 and the second front fork rod 7 are slidably connected to the inner wall of the connecting through hole 2, and the diameter of the limiting ring 9 is larger than the inner diameter of the connecting through hole 2. In this embodiment, the limiting ring 9 on the front fork rod can limit the front fork connecting plate 1 to prevent the front fork connecting plate 1 from sliding downward and control the range of movement of the front fork connecting plate 1. An oil overflow port 11 is fixed on the surface of the inner wall of the connecting through hole 2. The utility model fixes the front fork rods together by threaded connection, thereby facilitating the user to disassemble the electric bicycle front fork and improving the efficiency of disassembly and assembly. The front fork also facilitates the lubricating oil application operation on the interface of the front fork rod, further making the electric bicycle front fork easy to disassemble and assemble, providing convenience for the user's daily maintenance and repair work, and solving the problem that the current electric bicycle front fork is inconvenient to disassemble and assemble, which brings inconvenience to maintenance and repair work.

[0020] The top of the surface of the first front fork rod 6 and the bottom of the surface of the second front fork rod 7 are both bolted with a disassembly piece 10, and the disassembly piece 10 is set in a hexagonal shape. In this embodiment, since the first front fork rod 6 and the second front fork rod 7 are fixed to the connecting pipe 3 through a threaded connection, in order to facilitate the user to disassemble the first front fork rod 6 and the second front fork rod 7, a disassembly piece 10 is provided on the surface of the first front fork rod 6 and the second front fork rod 7 so that the front fork rods can be disassembled with a wrench.

[0021] The interior of the front fork connecting plate 1 is hollow, and the oil overflow port 11 is connected to the interior of the front fork connecting plate 1. There are several oil overflow ports 11, and they are distributed in a ring shape on the inner wall surface of the connecting through hole 2. In this embodiment, the lubricating oil can be discharged to lubricate the interface of the front fork rod, which facilitates subsequent disassembly work.

[0022] The top of the front fork connecting plate 1 is connected to an oil inlet 12, and a dust cover 13 is provided on the surface of the oil inlet 12. In this embodiment, the user can regularly inject lubricating oil into the front fork connecting plate 1, and lubrication maintenance operations can be performed without disassembling the front fork.

[0023] Working principle: When the front fork of the electric bicycle fails or needs to be disassembled for maintenance, the user first uses a tool to fix the second front fork rod 7, and then rotates the first front fork rod 6 above to remove the first front fork rod 6 from the surface of the connecting tube 3, and then pulls the first front fork rod 6 and the second front fork rod 7 on the upper and lower sides to complete the disassembly of the front fork rod. The user can then perform maintenance and repair operations on the front fork rod. After the maintenance is completed, the staff inserts the connecting tube 3 at the top of the second front fork rod 7 into the connecting through hole 2 again, and connects the bottom of the first front fork rod 6 with the connecting tube 3, and assembles the first front fork rod 6 and the second front fork rod 7. After the assembly is completed, the dust cover 13 is opened again, and a certain amount of lubricating oil is injected into the interior of the front fork connecting plate 1 through the oil inlet 12, so that the lubricating oil flows out from the oil overflow port 11 and flows on the surface of the fixing ring 4. The lubricating oil flows into the interface of the first front fork rod 6 and the second front fork rod 7 to lubricate the front fork rod, which is convenient for subsequent disassembly operations.
