[0030] In the accompanying drawings, the same parts use the same reference numerals. The drawings are not drawn to scale. Detailed Implementation

[0031] To make the technical solutions and advantages of the present invention clearer, exemplary embodiments of the present invention will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not an exhaustive list of all embodiments. Furthermore, without conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0032] Embodiments of the present invention provide a sliding door threshold device. For example... Figure 1 As shown, the sliding door sill device includes a side outer panel 1, a sill outer panel 2, a guide rail box 3, and a sill inner panel 4. The side outer panel 1, as part of the side wall of the vehicle, mainly serves to cover components such as the sill outer panel 2. The sill outer panel 2 is located on the lateral inner side of the side outer panel 1 (the lateral inner side here refers to the side closer to the center of the vehicle body, with reference to the vehicle's own orientation). According to this application, the height of the front section of the sill outer panel 2 is higher than the height of the rear section. That is, the sill outer panel 2 has a front section and a rear section; the front section has a high Z-axis cross-section, while the rear section mainly forms the sliding door area and transitions to a low Z-axis cross-section from the front section. Figure 4 and 5 As shown, the front section of the outer threshold panel 2 has a first vertical edge 21. A guide rail box 3 is located at the rear section of the outer threshold panel 2, and is situated on the inner lateral side of the outer threshold panel 2. The opening of the guide rail box 3 faces outwards, and a sliding door guide rail 31 is suspended from the top plate, as shown... Figure 3 As shown. A second vertical edge 32 is provided on the top wall of the opening of the guide rail box 3. According to this application, the second vertical edge 32 and the first vertical edge 21 are flush with each other in the front-to-back direction to form a sealing edge. The inner sill plate 4 is provided on the transverse inner side of the outer sill plate 2. The front section of the upper side of the inner sill plate 4 is connected to the outer sill plate 2 and the rear section is connected to the guide rail box 3, and the lower side is connected to the outer sill plate 2.

[0033] Therefore, in this application, the second vertical edge 32 and the first vertical edge 21 are flush-joined in the front-to-back direction to form a sealing edge as the main sealing surface of the sliding door, used for the door sealing strip to engage, thereby ensuring a smooth and flat sealing structure and achieving an aesthetically pleasing opening effect. At the same time, the sliding door guide rail 31 is suspended on the top wall of the guide rail box 3, which helps to maximize the effective utilization of the Z-axis space.

[0034] In one embodiment, such as Figure 2 and 3As shown, the guide rail box 3 is a spliced ​​structure, including an upper cover 33 and a lower cover 34 arranged vertically. The upper cover 33 has a first plate 331, a second plate 332, and a third plate 333 connected in sequence. The lower cover 34 has a fourth plate 341 and a fifth plate 342 connected in sequence. The first plate 331 extends vertically to form a second vertical edge 32. The third plate 333 and the fourth plate 341 both extend vertically and overlap, for example, by welding, to connect the upper cover 33 and the lower cover 34. The second plate 332 and the fifth plate 342 extend horizontally and, together with the fourth plate 341 and the third plate 333, form a receiving cavity with the guide rail box 3 opening laterally outward. The fifth plate 342 is used to connect to the rear section of the outer sill plate 2. The sliding door guide rail 31 is suspended on the second plate 332. Furthermore, the second plate 332 and the fifth plate 342 are arranged opposite each other and both extend horizontally, with an inwardly protruding triangular protrusion 35 at their front ends. This design facilitates the installation of the sliding door guide rail 31, allowing for the curved extension of the guide rail 31. Furthermore, the guide rail box 3 has a simple structure and is easy to implement.

[0035] The lower cover 34 also has a sixth plate 343 connected to the fifth plate 342. The sixth plate 343 and the fifth plate 342 form a corner connection structure that overlaps the rear section of the outer sill plate 2. Understandably, the rear section of the outer sill plate 2 also forms a bent corner connection structure to achieve a stable connection between the guide rail box 3 and the outer sill plate 2.

[0036] An extruded aluminum profile 5 is provided between the outer sill plate 2 and the inner sill plate 4. The extruded aluminum profile 5 is located at the lower end of the guide rail box 3. This extruded aluminum profile 5 can improve side impact resistance, and especially when this sliding door sill device is applied to electric vehicles, it can also effectively protect the electric vehicle battery. Figure 8 and 9 As shown, the extruded aluminum profile 5 is a longitudinally extending cylindrical beam, and to improve strength, frame-like stiffening plates 51 are provided inside the cylindrical beam. This configuration of the extruded aluminum profile 5 not only meets the strength requirements but also has advantages such as light weight.

[0037] like Figure 6 and 7 As shown, a connecting bracket 6 is provided at the front end of the extruded aluminum profile 5. The connecting bracket 6 is constructed in the shape of a bent plate. One side of the connecting bracket 6 is used to connect to the extruded aluminum profile 5, for example, by bolt 61. The vertical side of the connecting bracket 6 is used to overlap with the first vertical edge 21 and the third vertical edge 41 provided on the inner sill plate 4 to form the main sealing surface. That is, the extruded aluminum profile 5 is connected to the outer sill plate 2 and the inner sill plate 4 by the connecting bracket 6. It can be understood that multiple connecting brackets 6 can be provided at the front end of the extruded aluminum profile 5 to achieve a stable connection, depending on actual needs.

[0038] The inner sill plate 4 is constructed as a U-shaped groove with a flange facing laterally outward. The upper flange of the inner sill plate 4 forms a third vertical edge 41, and the lower flange forms a fourth vertical edge 42. The extruded aluminum profile 5 and the guide rail box 3 are accommodated within the U-shaped groove of the inner sill plate 4.

[0039] A fifth vertical edge 22 is provided on the lower side of the outer sill plate 2 for welding connection to the fourth vertical edge 42. That is, after the lower side of the outer sill plate 2 surrounds the extruded aluminum profile 5, it is fixedly connected to the inner sill plate 4.

[0040] In this application, the side panel 1 is manufactured using a drawing process. The sill inner panel 4 is manufactured using a roll forming process. The front section of the sill outer panel 2 is formed using a molding process, and the rear section is rolled using a roll forming process. The upper and lower covers of the guide rail box 3 are manufactured using a molding process and then welded to the sill outer panel 2. The extruded aluminum profile 5 is formed using an aluminum extrusion process.

[0041] During installation, the inner sill plate 4 is conventionally welded at the lower body station. The extruded aluminum profile 5 and connecting bracket 6 are screwed together at the assembly station, then fed to the lower body via the Y-axis, and welded to the third vertical axis 41 via the connecting bracket 6. The assembly of the outer sill plate 2 and guide rail box 3 is welded to the outer side panel 1 at the assembly station, and connected to the rear section of the outer sill plate 2 via the fifth plate 342 and the sixth plate 343. A 3-5mm gap is maintained between the outer side panel 1 and the outer sill plate 2 in the transverse (Y-axis) direction to allow for the flow of electrophoretic fluid. Figure 8 The front section of the side panel 1 is spot-welded to the first vertical edge 21 of the sill panel 2 via an upward flange. The assembly of the sill panel 2, the guide rail box 3, and the side panel 1 is welded to the lower body via a Y-axis upward feed. Specifically, the first vertical edge 21 on the upper side is welded to the third vertical edge 41, while the fifth vertical edge 22 on the lower side is welded to the fourth vertical edge 42.

[0042] This application also includes a car. The car includes the aforementioned sliding door sill device. The sliding door sill device of this application has a simple structure, can effectively overlap, and achieves an aesthetically pleasing appearance. It is compact, widely applicable, and can be adapted to different car models by changing its longitudinal length. It improves side-impact safety and enhances usability.

[0043] In this application, the directional terms "front", "rear", "left", "right", "lateral", "longitudinal", "vertical", "up" and "down" are all based on the vehicle's orientation.
