[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0030] This utility model provides, for example Figures 1-4 The illustrated automotive sheet metal stamping part includes a sheet metal part 1, a fixing cylinder 4, and a disassembly and assembly mechanism. The sheet metal part 1 has a threaded hole 5 on its outer wall for connecting to the sheet metal part 1. The fixing cylinder 4 is movably disposed on the outer wall of the sheet metal part 1. A movable plate 7 is movably disposed on the inner wall of the fixing cylinder 4. A positioning plate 6 is fixedly connected to the outer wall of the movable plate 7. The disassembly and assembly mechanism is disposed inside the fixing cylinder 4 and is used to disassemble and assemble the positioning plate 6. The positioning plate 6 is a tapered plate that guides the movement of bolts and bears shear force. Through this division of labor, the overall shock resistance of the sheet metal part 1 is improved. The sheet metal stamping part that mates with the sheet metal part 1 is provided with a through groove. The fixed cylinder 4 can be inserted into the through slot. During installation, the bolt is first inserted into the fixed cylinder 4 from another sheet metal stamping part. After the bolt opens the positioning plate 6, it mates with the threaded hole 5. The threaded hole 5 acts as a nut. In specific use: the sheet metal part 1 is fixed by using the threaded hole 5 to mate with the bolt. During installation, the fixed cylinder 4 is inserted into another sheet metal stamping part or the body mating hole. During the movement of the bolt, the positioning plate 6 is used to position and guide the bolt. During the movement of the bolt, the positioning plate 6 is opened until the bolt mates with the threaded hole 5. At the same time, the positioning plate 6 is used to clamp the outer wall of the bolt to reduce the bolt movement range during vibration and protect the bolt.

[0031] One aspect is that the disassembly and assembly mechanism includes a snap-fit ​​structure and a control structure. The snap-fit ​​structure includes a limiting groove 13 and a limiting block 12. The limiting groove 13 is opened on the inner wall of the movable plate 7, and the limiting block 12 is snapped into the inner wall of the limiting groove 13. An elastic component is provided on the outside of the limiting block 12. The elastic component includes a sliding plate 11. A deep groove 9 is opened on the inner wall of the fixed cylinder 4. The sliding plate 11 is slidably connected to the inner wall of the deep groove 9. A spring 8 is fixedly connected to the sliding plate 11 and the inner wall of the deep groove 9. The side of the sliding plate 11 away from the spring 8 is fixedly connected to the outer wall of the limiting block 12. The positioning plate 6 will inevitably wear during use. When the wear is excessive, it needs to be replaced. An embedding groove is opened on the inner wall of the fixed cylinder 4. The movable plate 7 can be embedded in the embedding groove. The movable plate 7 is fixed by the snap-fit ​​between the limiting block 12 and the limiting groove 13. The positioning plate 6 can be quickly disassembled by the snap-fit ​​between the limiting block 12 and the limiting groove 13.

[0032] On the other hand, the control structure includes a fixed plate 14 and a pull plate 10. The fixed plate 14 is fixedly connected to the inner wall of the deep groove 9. A connecting block 15 is slidably connected to the inner wall of the fixed plate 14. The connecting block 15 is fixedly connected to the top of the slide plate 11. The pull plate 10 is fixedly connected to the end of the connecting block 15 away from the slide plate 11. A buckle groove is provided on the outer wall of the pull plate 10. The buckle groove allows the worker to pull the pull plate 10 to move. In specific use: when it is necessary to disassemble the positioning plate 6, the worker pulls the pull plate 10. The pull plate 10 drives the slide plate 11 to move through the connecting block 15. The slide plate 11 squeezes the spring 8. At the same time, the slide plate 11 drives the limit block 12 to move until the limit block 12 moves out of the limit groove 13, canceling the engagement with the movable plate 7. The worker can then pull out the movable plate 7 to achieve the purpose of quickly disassembling the positioning plate 6.

[0033] Preferably, the fixed cylinder 4 is provided with a fixing mechanism on the outside. The fixing mechanism includes a connecting plate 2 and a screw 3. The connecting plate 2 is fixedly connected to the bottom of the fixed cylinder 4, and the screw 3 is threadedly connected to the inner wall of the sheet metal part 1. The connecting plate 2 is movably sleeved on the outer wall of the screw 3. The connecting plate 2 is fixed by the connection between the screw 3 and the sheet metal part 1. The fixed cylinder 4 can be disassembled by the screw 3 and the connecting plate 2, which makes it convenient for workers to disassemble and install the positioning plate 6.

[0034] In addition, two positioning plates 6 are set up horizontally and symmetrically. The material of the positioning plates 6 is high-resilience TPE material. High-resilience TPE material has both high elasticity and wear resistance. It can quickly return to its original shape after being squeezed, stretched or twisted, with a rebound rate of 90%-98%. The high-resilience TPE material is used to make the positioning plates 6 always press against the outer wall of the bolt, which fixes and protects the bolt and prevents the bolt from loosening, making abnormal noise or failing due to external forces such as vibration or impact.

[0035] In practical use: During installation, a bolt is first inserted into the fixed cylinder 4 from another sheet metal stamping part. After the bolt opens the positioning plate 6, it engages with the threaded hole 5. The threaded hole 5 acts as a nut. The positioning plate 6 guides the movement of the bolt and bears the shearing force. Through division of labor, the overall shock resistance of the sheet metal part 1 is improved. When the positioning plate 6 needs to be removed, the worker pulls the pull plate 10. The pull plate 10 drives the slide plate 11 to move through the connecting block 15. The slide plate 11 compresses the spring 8. At the same time, the slide plate 11 drives the limit block 12 to move until the limit block 12 moves out of the limit groove 13, thus releasing the engagement of the movable plate 7. The worker can then pull out the movable plate 7 to achieve the purpose of quickly removing the positioning plate 6. During installation, the movable plate 7 is inserted into the inner wall of the fixed cylinder 4. The connecting block 15 is released, and the three-dimensional spring 8 returns to its original position, driving the slide plate 11 to move. The slide plate 11 drives the limit block 12 to engage inside the limit groove 13. The limit block 12 is used to fix the movable plate 7, thus achieving the purpose of installing the positioning plate 6.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
