[0030] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0031] The following will be combined with Figures 1 to 4, describe the sill assembly 100 provided in the embodiments of the present utility model.

[0032] Specifically, the sill assembly 100 includes a first sill 10 and a second sill 20.

[0033] Among them, the first sill 10 includes a first plate body portion 1, a first flanging portion 2, and a cavity structure 3. The first flanging portion 2 and the cavity structure 3 are respectively bent and formed at opposite ends of the first plate body portion 1. Optionally, referring to Figure 1 and Figure 2 shown, when the sill assembly 100 is in a use state, the first flanging portion 2 is connected to the lower end of the first plate body portion 1, and the cavity structure 3 is connected to the upper end of the first plate body portion 1. Both the first flanging portion 2 and the cavity structure 3 protrude from the same side surface of the first plate body portion 1.

[0034] The second sill 20 includes a second plate body portion 4, a second flanging portion 5, and a third flanging portion 6. The second flanging portion 5 and the third flanging portion 6 are respectively bent and formed at both side edges of the second plate body portion 4. Optionally, referring to Figure 1 and Figure 3 shown, when the sill assembly 100 is in a use state, the second flanging portion 5 is connected to the lower end of the second plate body portion 4, and the third flanging portion 6 is connected to the upper end of the second plate body portion 4. Both the second flanging portion 5 and the third flanging portion 6 protrude from the same side surface of the second plate body portion 4.

[0035] The first plate body portion 1 and the second plate body portion 4 are arranged opposite to each other. The second flanging portion 5 corresponds to and is connected to the first flanging portion 2, and the third flanging portion 6 corresponds to and is connected to the cavity structure 3. It can be understood that both the first flanging portion 2 and the cavity structure 3 protrude from the surface of the first plate body portion 1 facing the second plate body portion 4, and both the second flanging portion 5 and the third flanging portion 6 protrude from the surface of the second plate body portion 4 facing the first plate body portion 1.

[0036] In this embodiment, the cavity structure 3 of the first sill 10 is connected to the third flanging portion 6 of the second sill 20, and the first flanging portion 2 of the first sill 10 is connected to the second flanging portion 5 of the second sill 20. The cavity structure 3 is equivalent to a reinforcing rib formed between the first sill 10 and the second sill 20, thereby being able to improve the overall stiffness of the sill assembly 100, and further improving the ability of the sill assembly 100 to resist lateral loads. For example, it can improve the side collision resistance and column collision resistance of the sill assembly 100.

[0037] At the same time, the cavity structure 3 and the first folded edge portion 2 are respectively bent at the two ends of the first plate body portion 1, so that the first threshold 10 can constitute an integral structure. Similarly, the second folded edge portion 5 and the third folded edge portion 6 are bent at the two ends of the second plate body portion 4, so that the second threshold 20 can constitute an integral structure. In this way, there is no need to add reinforcing ribs separately, thereby improving the overall stiffness of the threshold assembly 100 without increasing the number of parts, thereby reducing the cost and manufacturing difficulty of the threshold assembly 100.

[0038] In addition, in the related art, the reinforcing ribs between the inner threshold and the outer threshold need to be installed and welded separately, which makes the processing technology of the threshold assembly more complicated. In the present application, the cavity structure 3 is bent and formed on the first threshold 10, and is integrally formed with other parts of the first threshold 10. Therefore, there is no need to install and weld the cavity structure 3 separately, thereby simplifying the processing technology of the threshold assembly 100 and reducing the processing difficulty of the threshold assembly 100.

[0039] refer to Figure 1 As shown, in some embodiments provided by the present invention, the third folded edge portion 6 is connected to the side of the cavity structure 3 away from the first folded edge portion 2. In this embodiment, by connecting the third folded edge portion 6 to the side of the cavity structure 3 away from the first folded edge portion 2, the cavity structure 3 can be arranged in the space surrounded by the first plate body portion 1, the first folded edge portion 2, the second plate body portion 4, the second folded edge portion 5 and the third folded edge portion 6, which is equivalent to adding reinforcing ribs inside the door sill assembly, thereby improving the utilization rate of the internal space of the door sill assembly and improving the mechanical properties of the door sill assembly without increasing the external dimensions of the door sill assembly.

[0040] refer to Figure 1 As shown, in some embodiments provided by the present invention, the cavity structure 3 is abutted against and connected to the second plate portion 4 .

[0041] In this embodiment, the cavity structure 3 abuts against and is connected to the second plate portion 4. On the one hand, the cavity structure 3 can connect the first plate portion 1 and the second plate portion 4, improving the connection strength between the first plate portion 1 and the second plate portion 4, thereby enhancing the overall strength of the sill assembly 100, and further improving the lateral load resistance and load-bearing capacity of the sill assembly 100. On the other hand, the cavity structure 3 can support the first plate portion 1 and the second plate portion 4, improving the stiffness of the first plate portion 1 and the second plate portion 4, reducing the deformation of the first plate portion 1 and the second plate portion 4, and thus enhancing the lateral load resistance performance and load-bearing performance of the sill assembly 100. On yet another hand, the cavity structure 3, together with the first flanging portion 2, the second flanging portion 5, and the third flanging portion 6, transfers the load between the first plate portion 1 and the second plate portion 4, enabling the first plate portion 1, the second plate portion 4, the cavity structure 3, the first flanging portion 2, the second flanging portion 5, and the third flanging portion 6 to jointly bear the lateral load, avoiding the problem of concentrated load on the first plate portion 1 or the second plate portion 4, and making the mechanical properties of the sill assembly 100 better. Finally, it can also avoid the problem of abnormal noise caused by friction or collision between the cavity structure 3 and the second plate portion 4.

[0042] Optionally, the cavity structure 3 is welded to the second plate portion 4. For example, the cavity structure 3 can be connected to the second plate portion 4 by plug welding.

[0043] Refer to Figure 1 and Figure 2 As shown, in some embodiments provided by the present utility model, the cavity structure 3 includes a first rib plate portion 301, a second rib plate portion 302, and a connecting plate portion 303.

[0044] Among them, the first rib plate portion 301 is connected to one end of the first plate portion 1. For example, as Figure 1 shown, the first rib plate portion 301 is connected to the upper end of the first plate portion 1. The second rib plate portion 302 is disposed between the first rib plate portion 301 and the first flanging portion 2, and there are spaces between the second rib plate portion 302 and the first rib plate portion 301 as well as between the second rib plate portion 302 and the first flanging portion 2. The second rib plate portion 302 is connected to the first rib plate portion 301 through the connecting plate portion 303, that is, both ends of the connecting plate portion 303 are respectively connected to the first rib plate portion 301 and the second rib plate portion 302. The second rib plate portion 302 abuts against and is connected to the first plate portion 1.

[0045] In this embodiment, both the first rib portion 301 and the second rib portion 302 of the cavity structure 3 are supported and connected between the first plate portion 1 and the second plate portion 4. In fact, it is equivalent to arranging two ribs between the first plate portion 1 and the second plate portion 4, thereby ensuring the support effect and connection strength for the first plate portion 1 and the second plate portion 4. The first rib portion 301 and the second rib portion 302 are connected by a connecting plate portion 303, which can improve the connection strength and stiffness between the first rib portion 301 and the second rib portion 302, and ensure the overall mechanical properties of the cavity structure 3.

[0046] Optionally, the second rib portion 302 can be welded to the first plate portion 1, for example, including but not limited to laser welding.

[0047] Optionally, the connecting plate portion 303 is connected to the second plate portion 4 to avoid the problem of abnormal noise caused by friction or collision between the connecting plate portion 303 and the second plate portion 4. Optionally, the connecting plate portion 303 is welded to the second plate portion 4. For example, the connecting plate portion 303 and the second plate portion 4 can be connected by plug welding.

[0048] Reference Figure 1 and Figure 2 As shown in

[0049] In this embodiment, the second rib portion 302 is attached and connected to the first plate portion 1 through the first flanging 3021. The contact area between the first flanging 3021 and the first plate portion 1 is larger. On the one hand, it can improve the connection strength between the first flanging 3021 and the first plate portion 1. On the other hand, the load transmitted between the first plate and the second rib portion 302 can be distributed on a larger contact surface, avoiding the problem of stress concentration and improving the service life of the structure. Finally, as Figure 1 shown, since the first flanging 3021 is folded in the vertical direction, it is equivalent to adding a rib in the vertical direction to the sill assembly 100, thereby further improving the bending resistance of the sill assembly 100 and further enhancing the load-bearing capacity of the sill assembly 100.

[0050] Reference Figure 1 and Figure 3 As shown in

[0051] In this embodiment, the support plate portion 7 extends in the vertical direction, which is equivalent to adding a vertical rib between the third folded edge portion 6 and the cavity structure 3, that is, adding a vertical rib to the door sill assembly 100, thereby further improving the bending resistance of the door sill assembly 100, and further improving the load-bearing capacity of the door sill assembly 100.

[0052] Optionally, the support plate portion 7 is welded to the first rib portion 301 of the cavity structure 3 , for example, the support plate portion 7 can be laser welded to the first rib portion 301 .

[0053] refer to Figure 1 and Figure 3 As shown, in some embodiments provided by the present invention, a second flange 701 is provided at one end of the support plate portion 7 close to the cavity structure 3 , and the second flange 701 is attached to and connected to the cavity structure 3 .

[0054] In this embodiment, the support plate portion 7 is attached and connected to the cavity structure 3 through the second flange 701. The contact area between the second flange 701 and the cavity structure 3 is larger. On the one hand, the connection strength between the second flange 701 and the cavity structure 3 can be improved. On the other hand, the load transferred between the cavity structure 3 and the support plate portion 7 can be distributed on a larger contact surface, avoiding the problem of stress concentration and improving the life of the structure. Finally, as Figure 1 As shown, since the second flange 701 is folded in the horizontal direction, it is equivalent to adding a horizontal rib to the door sill assembly 100 , thereby further improving the ability of the door sill assembly 100 to resist lateral loads.

[0055] refer to Figure 1 and Figure 2 As shown, in some embodiments provided by the present invention, the second folded edge portion 5 is connected to the side of the first folded edge portion 2 facing away from the cavity structure 3, and the end of the first folded edge portion 2 facing away from the first plate body portion 1 is provided with a third flange 201, and the third flange 201 faces the cavity structure 3.

[0056] In this embodiment, by providing the third flange 201 on the first folding portion 2, and the second folding portion 5 is connected to the outside of the first folding portion, in the process of connecting the second folding portion 5 with the first folding portion 2, the third flange 201 is used to limit and guide the second folding portion 5 to avoid being inserted into the inside of the first folding portion 2, thereby ensuring the accuracy of the assembly of the threshold assembly 100, avoiding the problem of assembly errors, and improving the assembly efficiency. In addition, the third flange 201 is folded in the vertical direction, which is equivalent to adding a vertical rib plate to the threshold assembly 100, thereby further improving the bending resistance of the threshold assembly 100, and then improving the load-bearing capacity of the threshold assembly 100.
