[0002] In modern society, environmental protection has become a deeply ingrained concept, and electric vehicles have become an integral part of people's daily lives as a means of transportation. However, electric vehicles are used in harsh environments with complex road conditions. Therefore, protective end caps are often installed on both sides of the wheel hub to shield and protect the transmission components and parts inside the wheel hub. Electric vehicle wheel hub protective end caps are usually made of aluminum alloy, which has high requirements for adaptability to various environments and low failure rate.

[0003] However, most traditional protective end caps for electric vehicles are one-piece molded structures with relatively simple structures. When riding at night, they do not have reflective warning structures, so they are difficult for other vehicles to see, posing a safety hazard.

[0004] Furthermore, protective end caps are mostly installed on the outer end of rotating shafts and bearings to protect them. When lubrication of transmission components such as bearings is required, the end caps need to be frequently disassembled, which affects lubrication efficiency. Utility Model Content

Limiting grooves 8 are correspondingly opened at both ends of the mounting frame 2. The limiting ring 7 is located inside the limiting grooves 8. A mounting hole 9 is opened in the middle of the cover body 1. An annular cavity 10 is fixedly provided at the outer end of the mounting hole 9.

[0032] In this embodiment, oil leakage holes 11 are provided on the inner wall of the annular cavity 10. There are multiple oil leakage holes 11 arranged in a circular shape. An oil filling pipe 12 is fixedly provided on the outer wall of the annular cavity 10 at the upper end. The lower end of the oil filling pipe 12 is connected to the interior of the annular cavity 10. A baffle 13 is movably provided on one side of the annular cavity 10. A threaded ring 14 is fixedly provided on the inner wall of the baffle 13. The threaded ring 14 is threadedly connected to the inner wall of the annular cavity 10. All oil leakage holes 11 are connected to the interior of the mounting hole 9.

[0033] More specifically, by setting a reflector 3 inside the mounting frame 2, the light source projected from the outside can be reflected so that the vehicle can see clearly, thereby increasing the safety performance of the rider in low light conditions and improving practicality. When it is necessary to lubricate the transmission components of the electric vehicle, lubricating oil can be poured into the annular cavity 10 through the oil filling pipe 12. At this time, the lubricating oil will leak out of the annular cavity 10 through the oil leakage hole 11 and contact the bearing to achieve the lubrication effect, which is convenient for maintenance.

[0034] Please see Figure 1 and Figure 6As an embodiment for lubricating the connection position of the cover 1: an outer ring 15 is fixedly provided at the periphery of the cover 1. An outer hole 16 is provided on the outer wall of the outer ring 15. A connecting screw 17 is provided inside the outer hole 16. An oil storage cavity 18 is provided inside the connecting screw 17. Lubrication holes 19 are provided on the inner wall of the oil storage cavity 18. Multiple lubrication holes 19 are provided and are evenly distributed.

A sealing plug 21 is provided inside the oil filling hole 20. The sealing plug 21 is threadedly connected to the inner wall of the oil filling hole 20.

[0035] Specifically, the user can install the cover 1 on both sides of the electric vehicle wheel hub and fix it with the connecting screws 17. Then, lubricating oil is injected into the oil reservoir 18 to lubricate the threaded position of the connecting screws 17, prevent rust, and facilitate subsequent disassembly and assembly.

[0036] Please refer to Figure 5 As a further embodiment of adding lubricating oil to the annular cavity 10: the upper end of the oil filling pipe 12 is provided with a threaded cap 22, which is threadedly connected to the outer wall of the oil filling pipe 12.

[0037] Specifically, the user can install the threaded cap 22 on the upper end of the refueling pipe 12 to seal it and prevent dust from entering.

[0038] In summary, when using the entire device: the user can install the cover 1 onto both sides of the electric vehicle's wheel hub and fix it with the connecting screws 17. Then, lubricating oil is injected into the oil reservoir 18, and the lubricating oil will leak out through the lubrication hole 19 to lubricate the threads of the connecting screws 17, preventing rust and facilitating subsequent disassembly and assembly. Next, the reflector 3 is installed in the mounting frame 2 so that the threaded post 4 enters the placement groove 5. Then, the fastening nut 6 is tightened so that the limiting ring 7 at its tail end enters the limiting groove 8, thus achieving the effect of fixing the reflector 3. By setting the reflector 3, the light source projected from the outside can be reflected so that the vehicle can see clearly, thereby increasing the safety performance of the electric vehicle in low-light conditions and improving its practicality. When it is necessary to lubricate the transmission components of the electric vehicle, lubricating oil can be poured into the annular cavity 10 through the oil filling pipe 12. At this time, the lubricating oil will leak out of the annular cavity 10 through the oil leakage hole 11 and contact the bearing to achieve the lubrication effect, which is convenient for maintenance.
