The oiling component 2 includes an oil storage tank 21, and the protective component 4 includes a flange 41. This ensures that by placing the fastening bolt 3 inside the connecting cylinder 23 and the fixing seat 24, contact with external substances is avoided by the sealing ring 25. At the same time, lubricating oil is periodically delivered to the inside of the connecting cylinder 23 through the connecting pipe 22 to perform oiling operations on the fastening bolt 3. Then, by inserting the flange 41 into the surface of the fastening bolt 3, when the fastening bolt 3 is connected to the vehicle body structure, the vehicle body compresses the spring washer 44, and the spring washer 44 rebounds and pushes the flange 41 to abut against the vehicle body structure, so that the fastener is tightly connected to the vehicle body structure.

[0027] In this embodiment, an oil reservoir 21 is fixedly connected to the top of the connecting seat 1. A connecting pipe 22 is fixedly connected inside the oil reservoir 21. A connecting cylinder 23 is fixedly connected to one end of the connecting pipe 22. A fixing seat 24 is fixedly connected to the bottom of the connecting cylinder 23. A sealing ring 25 is fixedly connected inside the fixing seat 24. By setting the oiling component 2, it is ensured that the fastening bolt 3 is placed inside the connecting cylinder 23 and the fixing seat 24. The sealing ring 25 prevents contact with external substances. At the same time, lubricating oil is periodically delivered to the inside of the connecting cylinder 23 through the connecting pipe 22 to perform oiling operations on the fastening bolt 3.

[0028] A connecting block 43 is slidably connected to the surface of the connecting groove 31. A flange 41 is fixedly connected to one end of the connecting block 43. A toothed block 42 is fixedly connected to one end of the flange 41. A spring washer 44 is fixedly connected to the other end of the flange 41. By setting the protective component 4, it is ensured that the flange 41 is inserted into the surface of the fastening bolt 3. When the fastening bolt 3 is connected to the vehicle body structure, the vehicle body compresses the spring washer 44. The spring washer 44 rebounds and pushes the flange 41 to abut against the vehicle body structure, so that the fastener is tightly connected to the vehicle body structure.

[0029] The connecting cylinder 23 has a threaded groove inside that matches the size of the fastening bolt 3. The fastening bolt 3 is installed and connected to the inside of the connecting cylinder 23 through the threaded groove, ensuring that the fastening bolt 3 can be threadedly connected and placed inside the connecting cylinder 23.

[0030] There are four sets of connecting cylinders 23, all located at the same center. The connecting cylinders 23 are distributed at equal angles on one side of the connecting seat 1. Each connecting cylinder 23 has a set of connecting pipes 22 connected to the oil tank 21, which ensures that the fastening bolts 3 inside the connecting cylinder 23 can periodically have lubricant flow into the connecting cylinder 23 through the connecting pipes 22, thus achieving the effect of oiling the surface of the fastening bolts 3.

[0031] Two sets of connecting grooves 31 are provided at equal angles on one side of the fastening bolt 3. The oil reservoir 32 is Y-shaped and is provided on the surface of the connecting groove 31. The oil reservoir 32 is five millimeters deep, which ensures that the lubricating oil of the fastening bolt 3 can be stored in the oil reservoir 32, thus ensuring that there is no need to frequently lubricate the fastening bolt 3.

[0032] There are ten sets of toothed blocks 42, all located at the same center. The toothed blocks 42 are distributed at equal angles at one end of the flange 41, which ensures that the flange 41 can further improve the stability of the connection between the fastening bolts 3 and the vehicle body structure through the toothed blocks 42.

[0033] The dimensions of the connecting block 43 are matched with the dimensions of the connecting groove 31. The connecting block 43 is engaged with the surface of the fastening bolt 3 through the connecting groove 31, which ensures that the flange 41 can be slidably disassembled on the surface of the fastening bolt 3 for regular inspection, thus ensuring the quality of the connection between the fastener and the vehicle body.

[0034] The working principle and usage process of this utility model: This utility model is a fastener protection device for new energy vehicles. When it is necessary to store automotive fasteners for corrosion protection, lubricating oil is placed inside the oil reservoir 21. Simultaneously, the lubricating oil enters the connecting cylinder 23 through the connecting pipe 22, and flows through the connecting groove 31 to the oil storage tank 32. The oil storage tank 32 stores a portion of the lubricating oil, ensuring the durability of the lubricating oil on the surface of the fastening bolt 3. At the same time, the sealing ring 25 within the fixing seat 24 prevents the surface of the fastening bolt 3 from being easily corroded. The corrosion and rust caused by contact with external substances ensure the strength of the fasteners in new energy vehicles. At the same time, when the fasteners are connected to the vehicle body structure, the flange 41 is connected to the surface of the fastening bolt 3 through the connecting groove 31. When the fastening bolt 3 is tightened to the new energy vehicle structure, the fastening bolt 3 contacts the surface of the vehicle structure and presses the spring washer 44. After being pressed, the spring washer 44 rebounds and pushes the flange 41, so that the toothed block 42 fits into the vehicle connector. This ensures that the fastening bolt 3 is not easy to loosen when the vehicle body vibrates, thus ensuring the driving experience of the driver.
