[0002] In automotive manufacturing, the design and manufacture of door sheet metal is crucial for ensuring overall vehicle performance and comfort. The structural design of the door directly impacts the vehicle's dust and noise reduction capabilities, as well as driving comfort. With increasing competition in the automotive industry, consumers are demanding increasingly higher performance from their vehicles.

[0003] Related prior art includes Chinese patent application "A Composite Door System," publication number CN212473052U. This composite door system comprises a door inner panel, an insert assembly, a door window frame assembly, a door outer panel bracket, and a door outer panel. The door inner panel, door outer panel bracket, and door outer panel are all made of composite materials. The insert assembly is assembled and welded from a door window frame insert, a B-pillar trim insert, a door hinge insert, a door water-cut window sill insert, and a door sill insert.

[0004] Traditional door angles are typically installed directly onto the door sheet metal. However, due to the inconsistent door sheet metal shapes across various OEMs, door angle structures also vary. The installation of the door angle and door sheet metal must be performed to avoid problems such as misalignment and partial collapse. These defects not only affect the product's appearance but also reduce its dust and noise reduction capabilities. To improve this situation, a door angle structure with a built-in insert has been designed to effectively prevent the intrusion of dust and noise, improving the overall vehicle performance and user experience.

The insert structure can improve the rigidity of the corner, and the snap-fit ​​assembly enables the corner to fit tightly with the door sheet metal.

[0006] The technical solution adopted in this application is: a car door sill corner assembly, including a door sheet metal, a door corner, an insert and a snap-on assembly, the snap-on assembly including a base and at least two snap-on parts arranged on the base, the snap-on assembly is installed on the insert through the base, the insert is embedded in the door corner, the snap-on part passes through the door corner, a snap-on hole corresponding to the snap-on part is provided on the door sheet metal, the snap-on part is snap-oned with the snap-on hole, and the door corner is fixed to the door sheet metal through the snap-on assembly.

[0007] Compared with the prior art, the advantages of the present application are that, first, the present application adds an insert structure in the door corner, which significantly improves the rigidity of the car door sill corner, enhances the stability of the overall structure, and reduces the risk of deformation and damage during use. Secondly, the present application adopts a snap-on assembly, which includes at least two snap-ons. The design of the snap-on assembly enables a tighter fit between the corner and the door sheet metal, avoiding problems such as poor seam fit and partial collapse that may occur in traditional designs, thereby improving product quality. The design of the snap-on assembly and the clip hole simplifies the installation process, improves production efficiency, and reduces manufacturing costs. And the snap-on assembly includes at least two snap-ons, which can well fix the relative position of the door corner and the door sheet metal through at least two snap-ons, avoiding the door corner from shaking relative to the door sheet metal. Finally, the design of the car door sill corner assembly of the present application can adapt to the door structures of different OEMs, has better versatility, and reduces installation problems caused by structural differences.

[0008] In some embodiments of the present application, the outer circumference of the base is provided with a limit groove, the insert is provided with a mounting groove adapted to the base structure, and the inner wall of the mounting groove is provided with an extension, which is adapted to the limit groove structure; the base is inserted into the insert mounting groove, and the extension extends into the limit groove. In the present application, the installation of the clamping assembly and the insert adopts an insert-type clamping installation, which is more efficient and convenient, and reduces assembly costs.

[0009] In some embodiments of the present application, the mounting groove extends through the top surface of the insert, and the snap-on assembly is inserted downwardly from the top surface of the insert into the mounting groove. The extension is located on the bottom surface of the inner wall of the mounting groove and on the side surface that connects to the bottom surface. The mounting groove extends through the top surface of the insert, facilitating the insertion of the snap-on assembly. The provision of the extension effectively limits the displacement of the snap-on assembly in the front-to-back direction.

[0010] In some embodiments of the present application, the retaining groove is U-shaped and disposed at the bottom and two side edges of the base. Inwardly curved depressions are disposed on both sides of the retaining groove, and the bottom surfaces of the depressions smoothly transition into the bottom surfaces of the retaining grooves. The U-shaped retaining groove design effectively limits the movement of the snap assembly, enhances the stability of the connection, and prevents loosening due to vibration.

[0011] In some embodiments of the present application, the extension is a U-shaped sheet structure, and protrusions adapted to the recess are provided on the inner walls on both sides of the extension; when the snap-fit ​​assembly is installed in the insert, the protrusions of the extension are embedded in the recess.

[0012] In this application, the extension extends into the limit groove, acting as a limit in the direction perpendicular to the insert, that is, limiting the forward and backward movement of the clamping assembly. The structural setting of the installation groove can also limit the further downward movement of the clamping assembly. This application further changes the structure of the limit groove and cooperates with the setting of the protrusion on the extension. After the clamping assembly is installed on the insert, the protrusion is embedded in the recess after the two are installed in place, limiting the relative displacement of the clamping assembly and the insert within the plane of the insert, and the installation of the two is now stable.

[0013] In some embodiments of the present application, the insert is a planar plate-like structure, the front side of the base is a planar structure, and the clip is mounted on the front side of the base. When installing the door corner to the door sheet metal, it is preferable to find a location where the mating surfaces of the two are planar and to construct the connecting structure at this location to ensure a more stable and reliable connection between the two.

[0014] In some embodiments of the present application, the clamping member includes a connecting plate arranged perpendicular to the base, and claws are respectively connected to both sides of the connecting plate. The two claws are symmetrically arranged, and the claws are connected to the connecting plate only by the top surface and one side.

[0015] In this application, the claw structure allows for a certain amount of deformation while maintaining good connection stability. This means that compared to conventional fasteners, the claw is stiffer and less likely to deform under the same applied force, making it more suitable for fitting door corners and door sheet metal.

[0016] In some embodiments of the present application, a fastener is further provided. The door angle and the door sheet metal have mounting holes coaxially disposed thereon. The fastener passes through the mounting holes of the door angle and the mounting holes of the door sheet metal, respectively, to fasten the two. The present application further provides a fastener to connect the door angle to the door sheet metal, thereby enhancing the reliability of the overall structure after the connection.

[0017] In some embodiments of the present application, the fastener includes a base support, a connecting column and two claws, the two claws are installed at one end of the connecting column, and the base support is connected to the other end of the connecting column. The claws pass through the mounting holes of the door corner and the mounting holes of the door sheet metal in sequence, and the base support is located inside the door corner.

[0018] In some embodiments of the present application, the latch further comprises an elastic member, which is disposed outside the connecting post and positioned between the door corner and the door sheet metal. In the present application, the elastic member acts as a shock absorber to prevent the door corner from colliding with the door sheet metal and generating unusual noise.

[0019] The above embodiments can be combined arbitrarily based on the common knowledge in this field. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The clip 6 extends through the door corner 2. The door sheet metal 1 is provided with a corresponding latching hole for the clip 6. The clip 6 engages with the latching hole, and the door corner 2 is secured to the door sheet metal 1 via the clip assembly 4. The design of the clip assembly 4 enables a tighter fit between the corner and the door sheet metal 1, avoiding problems such as loose joints and partial collapse that can occur in traditional designs, thereby improving product quality.

[0034] The vehicle door sill corner assembly design of the present application can adapt to the door structures of different OEMs, has better versatility, and reduces installation problems caused by structural differences.

[0035] Example 2, as Figures 5 to 8 As shown, the outer circumference of the base 5 is provided with a limit groove 7, and the insert 3 is provided with a mounting groove 8 adapted to the structure of the base 5. The inner wall surface of the mounting groove 8 is provided with an extension 9, which is adapted to the structure of the limit groove 7; the base 5 is inserted into the mounting groove 8 of the insert 3, and the extension 9 extends into the limit groove 7. In this application, the installation of the clamping assembly 4 and the insert 3 adopts an insert-type clamping installation, which is more efficient and convenient to install, and reduces assembly costs.

[0036] The mounting groove 8 extends through the top surface of the insert 3, and the snap-on assembly 4 is inserted downward from the top surface of the insert 3 into the mounting groove 8. The extension 9 is located on the bottom surface of the inner wall of the mounting groove 8 and on the side surface that connects to the bottom surface.

The provision of the extension 9 effectively limits the displacement of the snap-on assembly 4 in the front-to-back direction.

[0037] The limiting groove 7 is a U-shaped structure provided at the bottom and two side edges of the base 5. Inwardly curved recesses 10 are provided on both sides of the limiting groove 7. The inner bottom surface of the recess 10 smoothly transitions with the inner bottom surface of the limiting groove 7. The design of the U-shaped limiting groove 7 effectively limits the movement of the buckle assembly, enhances the stability of the connection, and prevents loosening due to vibration.

[0038] The edge extension 9 is a U-shaped sheet structure, and protrusions adapted to the recess 10 are provided on the inner walls on both sides of the edge extension 9 ; when the clamping assembly 4 is installed in the insert 3 , the protrusions of the edge extension 9 are embedded in the recess 10 .

[0039] In this application, the edge 9 extends into the limit groove 7, acting as a limit in a direction perpendicular to the insert 3, that is, limiting the forward and backward movement of the clamping assembly 4. The structural arrangement of the mounting groove 8 can limit further downward movement of the clamping assembly 4.
