[0040] Reference is made below to Figures 1-6 The sealing structure 10 provided by the embodiments of the present application is described.

[0041] As Figures 1-6 shown, the sealing structure 10 provided by the embodiments of the present application comprises a framework 1.

[0042] Specifically, referring to Figures 1-6 , the sealing structure 10 is used in a rocker assembly 100, the rocker assembly 100 comprises a rocker 20, the rocker 20 has a cavity 203 penetrating through the rocker 20 along the length direction of the rocker 20. It should be noted that the cavity 203 is provided on one hand to reduce the weight of the rocker 20, which is conducive to the light weight and economy of the vehicle. On the other hand, the cross section of the rocker 20 perpendicular to the length direction of the rocker 20 is increased, thereby improving the structural strength of the rocker 20.

[0043] Further, as Figures 1-6 shown, the framework 1 is arranged at one end of the cavity 203 along the length direction of the rocker 20, and is used to block the cavity 203. The framework 1 has a protruding part 11 extending into the cavity 203. The side of the framework 1 away from the rocker 20 has a groove 12 corresponding to the position of the protruding part 11. The inner peripheral wall of the groove 12 is inclined away from the interior of the groove 12 along the direction from the framework 1 to the rocker 20.

[0044] It can be understood that the protruding part 11 extends into the cavity 203, thereby achieving the blocking of the cavity 203 by the framework 1, thereby reducing the probability of liquid entering the cavity 203 and improving the waterproof performance of the rocker 20. The inner peripheral wall of the groove 12 is inclined away from the interior of the groove 12 along the direction from the framework 1 to the rocker 20, thereby enabling the liquid to flow out of the groove 12 along the inner peripheral wall of the groove 12, thereby reducing the retention of the liquid in the groove 12, i.e. reducing the retention of the liquid on the framework 1, thereby further reducing the probability of liquid entering the cavity 203 from both ends of the length direction of the rocker 20 and further improving the waterproof performance of the rocker 20.

[0045] In addition, the side of the framework 1 away from the rocker 20 has the groove 12 corresponding to the position of the protruding part 11, thereby enabling the protruding part 11 to be formed by stamping the framework 1. In this way, the processing of the protruding part 11 is simple, and no additional structure is needed to form the protruding part 11, thereby reducing the cost and weight.

[0046] Further, the sealing structure 10 is two, respectively, in the cavity 203 along the length of the two ends of the threshold 20, so as to achieve the sealing effect of the length of the two ends of the threshold 20, further improve the waterproof effect of the threshold 20.

[0047] Further, as shown in Figure 4 The cross section of the cavity 203 can be circular or rectangular, thereby increasing the irregularity of the cross section of the cavity 203, so that the structural strength of the threshold 20 is better.

[0048] The sealing structure 10 provided by the embodiment of the present application is arranged at one end of the cavity 203 along the length of the threshold 20 through the skeleton 1, and is used for plugging the cavity 203. The skeleton 1 has a protruding portion 11 extending into the cavity 203, thereby achieving the plugging of the cavity 203 by the skeleton 1, reducing the probability of liquid entering the cavity 203, and improving the waterproofness of the threshold 20. The side of the skeleton 1 away from the threshold 20 has a groove 12 corresponding to the position of the protruding portion 11. In the direction from the skeleton 1 to the threshold 20, the inner peripheral wall of the groove 12 is inclined toward the direction away from the inside of the groove 12, so that the liquid can flow out of the groove 12 along the inner peripheral wall of the groove 12, thereby reducing the retention of the liquid in the groove 12, further reducing the probability of liquid entering the cavity 203 from the two ends of the threshold 20 along the length, and further improving the waterproofness of the threshold 20.

[0049] In a possible implementation manner of the present application, as shown in Figures 1-6 The sealing structure 10 further comprises a foaming piece 2 arranged in the cavity 203 and surrounding the protruding portion 11. It should be noted that the foaming piece 2 is a light product produced by foaming technology, mainly composed of different resins (such as polystyrene, polyethylene, polypropylene, etc.) and auxiliary materials such as foaming agent after heating and foaming treatment. Its characteristic is that countless tiny bubbles are formed in the raw materials, so that the product volume expands and the density decreases. For example, in the present application, the foaming piece 2 is EVA (Ethylene Vinyl Acetate Copolymer, Ethylene Vinyl Acetate Copolymer), but the present application is not limited thereto. The foaming piece 2 can also be a polystyrene foaming piece, a polyethylene foaming piece, a polypropylene foaming piece, a polyurethane foaming piece or a polyvinyl chloride foaming piece, etc.

[0050] It can be understood that the foaming piece 2 has a high foaming ratio, and the volume of the foaming piece 2 increases after baking, so as to fill the gap between the protruding portion 11 and the inner wall of the cavity 203, thereby further avoiding the liquid from entering the cavity 203, and further improving the sealing and waterproofness of the threshold 20. It should be noted that the foaming piece 2 is connected with the protruding portion 11, for example, by a fastener.

[0051] For example, in the present application, the foaming piece 2 adopts a foaming ratio of 24 times, and after baking at a coating temperature of 170 DEG C, the foaming piece 2 can be fully foamed.

[0052] Further, the foaming piece 2 before foaming has a spacing, for example, 5 mm in the present application, from the inner wall of the cavity 203, so that the foaming piece 2 can smoothly extend into the cavity 203, avoiding assembly interference between the sealing structure 10 and the threshold 20.

[0053] In a possible implementation manner of the present application, as shown in Figure 6 the side of the protruding portion 11 facing the protruding direction has an annular groove 13, the annular groove 13 is arranged around the protruding portion 11, and the foaming piece 2 is in the annular groove 13, and the radial outer side of the annular groove 13 is open.

[0054] It can be understood that the annular groove 13 is arranged on one hand to facilitate positioning and placing the foaming piece 2, and on the other hand to make the foaming piece 2 directional foaming (foaming towards the radial direction and foaming into the cavity 203), avoiding the foaming piece 2 foaming in the direction away from the protruding direction of the protruding portion 11, thereby avoiding the foaming piece 2 overflowing to the end of the threshold 20 in the length direction.

[0055] In a possible implementation manner of the present application, as shown in Figure 1 the sealing structure 10 further comprises a sealing piece 3, the sealing piece 3 is arranged between the foaming piece 2 and the threshold 20, and the sealing piece 3 is arranged around the cavity 203. Among them, the sealing piece 3 is arranged on the side of the foaming piece 2 away from the inside of the cavity 203, and the sealing piece 3 is arranged opposite to the gap between the foaming piece 2 and the threshold 20, thereby further avoiding the liquid flowing into the cavity 203 through the gap between the foaming piece 2 and the threshold 20, thereby further improving the waterproofness and sealing property of the threshold 20.

[0056] In a possible implementation manner of the present application, the cavities 203 are spaced apart, and the protruding portions 11 and the grooves 12 are one-to-one corresponding to the plurality of cavities 203. It can be understood that the cavities 203 are spaced apart, thereby further improving the structural strength of the threshold 20. The protruding portions 11 and the grooves 12 are one-to-one corresponding to the plurality of cavities 203, thereby facilitating plugging each cavity 203, and further ensuring the sealing property of the threshold 20.

[0057] In a possible implementation manner of the present application, as shown in Figure 2 and Figures 4-6 the cavities 203 are spaced apart, and the protruding portions 11 and the grooves 12 are at least two. It can be understood that the cavities 203 are spaced apart, thereby further improving the structural strength of the threshold 20. The protruding portions 11 and the grooves 12 are at least two, thereby facilitating plugging the plurality of cavities 203, and further ensuring the sealing property of the threshold 20.

[0058] In a possible implementation of the present application, as shown in Figure 1 , Figure 2 , Figure 4 and Figure 5 , the threshold 20 comprises a profile body 201 and a reinforcing rib 202, the profile body 201 has a plurality of reinforcing ribs 202 extending along the length direction of the threshold 20, the plurality of reinforcing ribs 202 divides the space in the profile body 201 into a plurality of cavities 203, and the skeleton 1 is provided with a positioning clamp 14, which is adapted to be clamped on the reinforcing rib 202 or the profile body 201.

[0059] It can be understood that the plurality of reinforcing ribs 202 makes the structural strength of the threshold 20 better, and the existence of the positioning clamp 14 is beneficial to the initial positioning of the skeleton 1 on the threshold 20, thereby facilitating the assembly of the threshold 20 and the sealing structure 10 and improving the assembly efficiency. As shown in Figure 4 , the cross section of the reinforcing rib 202 can be linear or annular.

[0060] Further, as shown in Figure 5 , the positioning clamp 14 is a plurality of, thereby further improving the positioning reliability of the skeleton 1 on the threshold 20, thereby avoiding the relative displacement of the skeleton 1 and the threshold 20 during assembly and facilitating the assembly of the skeleton 1 and the threshold 20. In the example shown in Figure 5 , the positioning clamp 14 is two, but the present application is not limited thereto, and the positioning clamp 14 can also be more, for example, 3, 4, 5 or 6, etc.

[0061] In a possible implementation of the present application, as shown in Figure 1 , Figure 4 and Figure 5 , the skeleton 1 is provided with a positioning column 15 extending perpendicularly to the length direction of the threshold 20, and the threshold 20 is provided with a positioning hole 204 matched with the positioning column 15. Thus, the connection reliability of the threshold 20 and the skeleton 1 is improved, and the positioning reliability between the threshold 20 and the skeleton 1 is also improved.

[0062] Further, as shown in Figure 1 , Figure 4 and Figure 5 , the positioning column 15 is a plurality of spaced apart along the circumferential direction of the cross section of the threshold 20 perpendicular to the length direction, and the positioning hole 204 is a plurality of corresponding to the plurality of positioning columns 15, thereby further improving the connection reliability of the threshold 20 and the skeleton 1, and improving the positioning reliability between the threshold 20 and the skeleton 1.

[0063] For example, in Figure 4 and Figure 5In the shown example, the positioning holes 204 and the positioning columns 15 are 3, but the present application is not limited thereto, and the positioning holes 204 and the positioning columns 15 can be other numbers, such as 2, 4, 5, or 6, etc.

[0064] Further, as shown in Figure 1 , Figure 4 and Figure 5 , among the plurality of positioning columns 15, at least two of the positioning columns 15 have directions of extension perpendicular to each other, thereby enabling the framework 1 to be positioned in multiple directions perpendicular to the length direction of the rocker 20, further improving the connection reliability of the rocker 20 and the framework 1, and avoiding relative movement between the rocker 20 and the framework 1.

[0065] Further, the positioning column 15 has a certain deformation member, such as a rubber member, etc., thereby enabling the positioning column 15 to be extruded into the positioning hole 204 under the action of an external force, facilitating mutual positioning and cooperation between the plurality of positioning columns 15 and the plurality of positioning holes 204, and avoiding mutual interference when the plurality of positioning columns 15 are assembled into the plurality of positioning holes 204.

[0066] In a possible implementation manner of the present application, the included angle between the inner circumferential wall of the groove 12 and the length direction of the rocker 20 is 2-6°, such as 2°, 4°, 5°, or 6°. Thereby, the included angle between the inner circumferential wall of the groove 12 and the length direction of the rocker 20 is appropriate, on the one hand, ensuring that the included angle between the inner circumferential wall of the groove 12 and the length direction of the rocker 20 is large enough, which is conducive to the timely drainage of liquid from the groove 12, and on the other hand, avoiding that the included angle between the inner circumferential wall of the groove 12 and the length direction of the rocker 20 is too large, thereby resulting in that the overall area (the area perpendicular to the length direction of the rocker 20) of the framework 1 is too large.
