Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0019] Example 1:

[0020] Please refer to Figure 1. This utility model provides a tie rod for an automotive power steering system, including a tie rod body 1. A connecting block 2 is fixedly installed at the left end of the tie rod body 1. A working box 5 is fixedly installed at the top of the connecting block 2. A motor 6 is fixedly installed at the top of the working box 5. A threaded rod 12 is fixedly installed at the output end of the motor 6. A threaded sleeve 11 is threadedly installed on the front surface of the threaded rod 12. A compression plate 10 is fixedly installed at the bottom of the threaded sleeve 11 through a bracket. An oil bladder 9 is fixedly installed at the bottom of the inner cavity of the working box 5. A nozzle 4 is connected to the left side of the oil bladder 9 through a pipe.

[0021] This technical solution addresses the problem that existing tie rods lack automatic lubrication, requiring regular manual inspection and lubrication to maintain their proper function. Otherwise, the performance and reliability of the steering system may be affected, reducing market share, increasing driving risks for users, and failing to meet user needs.

[0022] Example 2:

[0023] Based on Embodiment 1, as shown in Figures 2 and 3, the present invention has a fixed bracket 3 fixedly installed on the left end of the working box 5, and the left end of the fixed bracket 3 fixedly installed on the right end of the nozzle 4. Both sides of the inner cavity of the working box 5 are fixedly installed with light rods 7, and slip rings 8 are slidably installed on the front surface of the light rods 7. The ends of the slip rings 8 that are close to each other are fixedly installed on both sides of the threaded sleeve 11 through the bracket.

[0024] By adopting the above technical solution, the setting of the fixed bracket 3 achieves the effect of multiple support for the nozzle 4, and the setting of the smooth rod 7 and the slip ring 8 achieves the effect of limiting the threaded sleeve 11.

[0025] Example 3:

[0026] As shown in Figures 1-4, the present invention includes an epoxy zinc-rich primer layer 101, an epoxy iron oxide red primer layer 102 coated on the outer surface of the epoxy zinc-rich primer layer 101, a red lead anti-rust paint 103 coated on the outer surface of the epoxy iron oxide red primer layer 102, a polyurethane resin layer 104 coated on the outer surface of the red lead anti-rust paint 103, and a polyurethane resin layer 104 coated on the outer surface of the red lead anti-rust paint 103. The thickness of the red lead anti-rust paint 103 is 0.03 mm, and the thickness of the polyurethane resin layer 104 is 0.02 mm.

[0027] The above technical solution, through the setting of epoxy zinc-rich primer layer 101, has the advantages of good mechanical properties, high hardness, good plasticity, water resistance, rust prevention and corrosion resistance. Through the setting of epoxy iron oxide red primer layer 102, it has excellent rust prevention, water resistance and chemical corrosion resistance, and good adhesion after coating. Through the setting of red lead anti-rust paint 103, it has the advantages of good penetration and wetting, soft paint film, strong adhesion and good rust prevention. Through the setting of polyurethane resin layer 104, it has the advantages of good softness, extensibility, transparency, cold resistance and processability.

[0028] The working principle of this utility model is as follows: the starting motor 6 drives the threaded rod 12 to rotate. The rotation of the threaded rod 12 drives the threaded sleeve 11 to adjust its height through the smooth rod 7 and the slip ring 8. The height adjustment of the threaded sleeve 11 drives the extrusion plate 10 to adjust its height. The extrusion plate 10 contacts the top of the oil bladder 9 and squeezes it. The extrusion of the oil bladder 9 drives the internal lubricant to be transported to the nozzle 4 through the pipeline. Then, the nozzle 4 automatically injects oil into the connecting block 2. The epoxy zinc-rich primer layer 101 has the advantages of good mechanical properties, high hardness, good plasticity, water resistance, rust prevention and corrosion resistance. The epoxy iron oxide red primer layer 102 has excellent rust prevention, water resistance and chemical corrosion resistance, and good adhesion after coating. The red lead anti-rust paint 103 has the advantages of good penetration and wetting, soft paint film, strong adhesion and good rust prevention. The polyurethane resin layer 104 has the advantages of good softness, extensibility, transparency, cold resistance and processability.
