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.

[0033] Reference Figures 1-4This utility model provides an embodiment of a quick-installation automotive metal part fastening bracket, including a bracket 1 and a vehicle frame 10. The bracket 1 and the vehicle frame 10 are detachably connected by a quick-installation assembly, providing an installation carrier for automotive metal parts. A quick-installation assembly is provided at the bottom of the bracket 1, which uses an elastic structure to achieve quick fixing and separation of the bracket 1 and the vehicle frame 10. A movable component is provided inside the bracket 1 to adjust the installation position of the metal parts to adapt to different needs. The bracket 1 is located on top of the vehicle frame 10, forming a hierarchical connection structure of the metal parts, the bracket 1, and the vehicle frame 10. A fastening bracket is provided in the middle of both sides of the surface of the vehicle frame 10. Through slots 11 allow the connecting block 2 of the quick-installation assembly to be inserted for initial positioning. Limiting slots 12 are formed on both sides of the inner wall of the two through slots 11, cooperating with the locking block 9 to form a locking structure to prevent the bracket 1 from loosening. The quick-installation assembly includes the connecting block 2, which serves as an intermediate structure connecting the bracket 1 and the vehicle frame 10, integrating the core components of the quick-installation function. The connecting block 2 is fixedly connected to the bottom of the bracket 1, making the bracket 1 and the connecting block 2 a rigid whole. Rectangular slots 3 are formed on both sides of the connecting block 2 to accommodate the spring 5 and limit the movement trajectory of the baffle 6. A cylindrical slot 4 is formed on one side of the inner wall of the two rectangular slots 3, cooperating with the sliding rod 7 to ensure sliding stability. Springs 5 ​​are fixedly connected to the inner wall of the 3rd section, providing reset power for the extension and retraction of the locking block 9. Baffles 6 are fixedly connected to one end of each of the two springs 5, transmitting the elastic force of the springs 5 ​​and driving the locking block 9 and the pressing block 8 in linkage. Sliding rods 7 are fixedly connected to the side of the two baffles 6 closest to the springs 5, sliding along the cylindrical groove 4 to prevent the baffles 6 from shifting. Pressing blocks 8 are fixedly connected to the bottom of the side of the two baffles 6 furthest from the springs 5. The arc design allows the locking block 9 to retract automatically when the connecting block 2 is inserted into the through groove 11. The locking block 9 is fixedly connected to the top of the side of the baffle 6 furthest from the springs 5, inserting into the limiting groove 12 to fix the bracket 1 to the vehicle frame 10. Sliding rods 7 are slidably connected in the cylindrical groove. The inner wall of the 4-section ensures that the baffle 6 moves in a straight line. The spring 5 is sleeved on the outside of the slide rod 7 to prevent the spring 5 from bending laterally when it extends and retracts. The baffle 6 is slidably connected to the inner wall of the rectangular groove 3, allowing the locking block 9 and the pressing block 8 to extend and retract flexibly. The locking block 9 is inserted into the limiting groove 12 and the connecting block 2 is fixed by insertion. The locking block 9 is inserted into one side of the rectangular groove 3 and can extend and retract within the rectangular groove 3 to cooperate with the limiting groove 12. The pressing block 8 is inserted into one side of the rectangular groove 3 to facilitate contact with the inner wall of the through groove 11 and to receive force. One side of the pressing block 8 is arc-shaped to reduce insertion resistance and make the installation smoother. The connecting block 2 is inserted into the inner wall of the through groove 11 to achieve the initial docking of the bracket 1 and the vehicle frame 10.

[0034] Reference Figure 1 , Figures 4-6The movable component includes a cylindrical groove 13, which provides installation space for the threaded rod 17 and the slider 15. The cylindrical groove 13 is located inside the bracket 1, allowing the movable component to be built into the bracket 1 to save space. The threaded rod 17 is rotatably connected to both sides of the inner wall of the cylindrical groove 13 via bearings. When rotated, the slider 15 is moved through the threaded drive. The slider 15 is threadedly connected to the outer side of the threaded rod 17, sliding along the groove 14 and driving the mounting plate 16 to move synchronously. The mounting plate 16 is fixedly connected to the top of the slider 15 for installing automotive metal parts and adjusting its position with the slider 15. One end of the threaded rod 17 passes through the bracket 1 and is fixedly connected to a handle 18, which facilitates manual rotation of the threaded rod 17 to adjust its position. A rotating shell 19 is fixedly connected to the middle of the front side of the bracket 1, providing an installation carrier for the rotating rod 20, the limiting plate 21, and the torsion spring 22. The rotating rod 20 is rotatably connected to the upper and lower sides of the inner wall of the rotating shell 19, serving as the limiting plate 21. The rotating shaft 1 has a limiting plate 21 fixedly connected to the outside of the rotating rod 20, which abuts against the handle 18 to fix its position. A torsion spring 22 is sleeved in the middle of the rotating rod 20 to provide a restoring elastic force for the limiting plate 21. One end of the torsion spring 22 is fixedly connected to the limiting plate 21 to transmit the elastic force of the torsion spring 22 to the limiting plate 21. The other end of the torsion spring 22 is fixedly connected to the inner wall of the rotating shell 19 to ensure that the torsion spring 22 is stably installed and generates deformation force. A sliding groove 14 is opened in the middle of the bracket 1 to limit the movement direction of the slider 15 and prevent it from rotating with the threaded rod 17. The cylindrical groove 13 is connected to the sliding groove 14 so that the slider 15 can be connected to the mounting plate 16. The slider 15 is slidably connected to the inner wall of the sliding groove 14 to ensure that the mounting plate 16 moves smoothly. The other end of the torsion spring 22 is fixedly connected to the inner wall of the rotating shell 19 to achieve the limiting effect of the torsion spring 22. The limiting plate 21 abuts against the outside of the handle 18 to fix the position of the threaded rod 17 by mechanical limiting.

[0035] Working principle: During installation, the connecting block 2 at the bottom of the bracket 1 is aligned with the through slot 11 of the vehicle frame 10 and inserted. During insertion, the locking blocks 9 on both sides of the connecting block 2 are squeezed by the inner wall of the through slot 11 because one side of the pressing block 8 is arc-shaped. Since the pressing block 8 is fixedly connected to the locking block 9 and the baffle 6, the three move synchronously. This causes the locking block 9 to retract into the rectangular slot 3, while the baffle 6 compresses the spring 5. The sliding rod 7 slides in the cylindrical slot 4. During this process, the pressing block 8 moves synchronously with the locking block 9. When the pressing block 8 passes the limiting slot 12, it will not insert into the limiting slot 12 because the inner wall of the through slot 11 continues to squeeze the locking block 9. When the connecting block 2 is fully inserted into the through slot 11, the pressing block 8 disengages from the through slot 11. When the locking block 9 reaches the position of the limiting slot 12, the spring 5 pushes the baffle 6 to reset, and the locking block 9 is inserted into the limiting slot. The groove 12 enables quick snap-fit ​​fixing of the bracket 1 to the vehicle frame 10. During disassembly, press the arc-shaped pressing blocks 8 on both sides to disengage the locking block 9 from the limiting groove 12, and then pull out the connecting block 2 to complete the disassembly. When adjusting the position of the mounting plate 16, first rotate the limiting plate 21 inside the rotating shell 19. The torsion spring 22 deforms under force, allowing the limiting plate 21 to disengage from the limit outside the handle 18. Then rotate the handle 18, which drives the threaded rod 17 to rotate in the cylindrical groove 13. Since the slider 15 is threadedly connected to the threaded rod 17 and the slider 15 is limited by the sliding groove 14, the rotation of the threaded rod 17 will cause the slider 15 to slide along the sliding groove 14, thereby driving the mounting plate 16 at the top to move. After adjusting to the appropriate position, release the limiting plate 21, the torsion spring 22 returns to its original position, and the limiting plate 21 re-abuts against the handle 18, limiting the rotation of the handle 18 and fixing the position of the mounting plate 16.
