[0020] Please refer to Figure 1 , which is a structural schematic view of a multifunctional automobile door sill buckle provided by the utility model. The multifunctional automobile door sill buckle comprises a door sill buckle body 10, a sheet metal inner buckle 20 arranged on the side of the door sill buckle body 10 facing the automobile sheet metal, a wire harness accommodating groove 30 arranged on the door sill buckle body 10 and facing the automobile guardrail, and two guardrail outer buckles 40 arranged on both sides of the wire harness accommodating groove 30 and facing the automobile guardrail. It can be conceived that the multifunctional automobile door sill buckle also comprises other functional modules, which are known to those skilled in the art, and will not be described here.

[0021] The multifunctional automobile door sill buckle is fixed on the automobile sheet metal and used for connecting with the automobile guardrail, and the wire harness of the automobile needs to pass through the multifunctional automobile door sill buckle. The automobile sheet metal, the automobile guardrail and the wire harness are prior art and will not be described here.

[0022] The door sill buckle body 10 is used for accommodating the functional components. A plurality of lightening grooves 11 are arranged between the wire harness accommodating groove 30 and the guardrail outer buckle 40 in the door sill buckle body 10 to reduce the amount of material used. The outer side of the lightening groove 11 is provided with a reinforcing rib 12. The door sill buckle body 10 is provided with at least two support blocks 13 on the side facing the automobile sheet metal. The support block 13 close to the sheet metal inner buckle 20 is arranged at the edge of the door sill buckle body 10, and the other support block 13 is arranged at an interval from one end of the door sill buckle body 10. In this embodiment, the other support block 13 is arranged below the support angle of the lightening groove 11. The support block 13 not only abuts against the automobile sheet metal, but also strengthens the structural strength of the door sill buckle body 10. The multifunctional automobile door sill buckle is integrally arranged to strengthen the overall structural strength.

[0023] The sheet metal inner buckle 20 is arranged towards the automobile sheet metal and between the two support blocks 13, and is used for installing the multifunctional automobile door sill buckle in the automobile sheet metal. The sheet metal inner buckle 20 includes an inner buckle body 21, a sealing ring 22 arranged at the connection between the inner buckle body 21 and the door sill buckle body 10, a movable groove 23 arranged on the inner buckle body 21 and below the sealing ring 22, and two pre-pressing devices 24 respectively connected to the slots of the movable groove 23. The inner buckle body 21 is provided with a sealing groove to install the sealing ring 22. The sealing ring 22 is used for sealing the connection between the automobile sheet metal and the sheet metal inner buckle 20 to prevent water from penetrating into the automobile sheet metal. The movable groove 23 is arranged through the inner buckle body 21. The sheet metal inner buckle 20 is made of plastic material, so that the sheet metal inner buckle 20 has good elasticity and anti-deformation ability. The sheet metal inner buckle 20 is installed to be arranged in the plug-in hole of the automobile sheet metal, and the pre-pressing device 24 is pressed into the movable groove 23. When the sheet metal inner buckle 20 is inserted into the plug-in hole of the automobile sheet metal, the pre-pressing device 24 is released, the sheet metal inner buckle 20 is pushed towards the automobile sheet metal, and the pre-pressing device 24 is reset and clamped with the plug-in hole.

[0024] The wire harness accommodating groove 30 is circular. The wire harness accommodating groove 30 is provided with a wire inlet 31 on the side of the automobile guardrail, for passing the automobile wire harness, so that the wire harness can enter the wire harness accommodating groove 30, and the installation of the automobile sheet metal and the automobile guardrail does not affect the arrangement of the automobile wire harness, thereby reducing the design volume of the automobile sheet metal. The wire inlet 31 is provided with a bayonet beam 311 at both ends. The wire harness accommodating groove 30 and the edge of the bayonet beam 311 are chamfered, so that the stress at the connection between the bayonet beam 311 and the wire harness accommodating groove 30 is reduced, thereby preventing the bayonet beam 311 from breaking at the connection with the wire harness accommodating groove 30. The bayonet beam 311 is arranged towards the center of the wire harness accommodating groove 30, and the lead-in angle is increased to facilitate the installation of the automobile wire harness. The length to thickness ratio of the bayonet beam 311 is in the range of 1:5 to 1:10, thereby reducing the stress on the bayonet beam 311 to prevent the bayonet beam 311 from breaking. The wire harness accommodating groove 30 is provided with a folding angle part 32 near one end of the wire inlet 31. The folding angle part 32 has multiple bending sections, which are used to increase the stress area on the side of the wire harness accommodating groove 30 near the wire inlet 31. One of the bayonet beams 311 is arranged on the folding angle part 32, and the folding angle part 32 increases the deformation space of the bayonet beam 311, reduces the pressure at the connection between the bayonet beam 311 and the wire harness accommodating groove 30, and prevents it from breaking.

[0025] Two guardrail outer buckles 40 are arranged on both sides of the wire harness accommodating groove 30 of the rocker buckle body 10. One of the guardrail outer buckles 40 is arranged near the automobile sheet metal, and the other is arranged near the automobile guardrail, so that the two guardrail outer buckles 40 are arranged at different heights. The guardrail outer buckle 40 comprises a resilient arm 41 arranged outside the wire harness accommodating groove 30, and the resilient arm 41, the wire harness accommodating groove 30 and the rocker buckle body 10 arranged therebetween form the guardrail outer buckle 40. The inner side of the guardrail outer buckle 40 is provided with a buckle groove 42, and the two sides of the groove opening of the buckle groove 42 are respectively provided with a buckle step 421, which prevents the buckle from falling out of the guardrail outer buckle 40 when the buckle in the automobile guardrail is displaced. The resilient arm 41 is bent away from the rocker buckle body 10, and forms an inlet with the folding angle part 32 for facilitating the entry of the automobile guardrail buckle.
