DETAILED DESCRIPTION

[0029] Figure 1 Structure diagram of the utility model, as Figures 1-4 shown, the door sill beam 1 in the embodiment includes the dry area pipe beam 101 and the barrier plate 2 buckled to the dry area pipe beam port, the edge of the barrier plate 2 extends to the inner cavity of the dry area pipe beam 101 and forms the guide part 201, the side surface of the barrier plate 2 facing the dry area pipe beam 101 is provided with the barrier glue 3 for forming primary sealing with the dry area pipe beam 101;The circumferential inner wall of the dry area pipe beam and the circumferential outer wall of the barrier plate are reserved with a functional gap, the functional gap is filled with sealing filler for sealing the barrier plate and the inner wall of the dry area pipe beam, forming secondary sealing between the dry area pipe beam 101 and the barrier plate 2.

[0030] The guide part 201 is formed by bending and extending from the periphery of the blocking plate 2 to the inner cavity of the dry area pipe beam 101, and the outer shape of the blocking plate 2 and the outer shape of the port of the dry area pipe beam 101 are matched to enable them to be matched in a snap-fit manner; the blocking plate 2 is arranged in the cavity of the dry area pipe beam 101, so that the guide part 201 faces the inner wall surface of the dry area pipe beam 101, which facilitates the arrangement of the blocking plate 2 on the dry area pipe beam 101, and the assembly convenience of the blocking plate 2 on the dry area pipe beam 101 is better, the assembly precision is higher, the guide part 201 formed by bending the periphery of the blocking plate 2 can reduce the assembly process, and the arrangement of the guide part 201 on the blocking plate 2 has strong connection strength.

[0031] As shown in Figure 3 , Figure 6 and Figure 7 , the blocking glue 3 is arranged on the side surface of the blocking plate 2 facing the dry area pipe beam 101, and the blocking glue 3 is surrounded in the circumferential direction by the guide part 201 formed on the blocking plate 2; the blocking glue 3 is selected from any one of the prior art.

[0032] The structure of the guide part 201 can guide the blocking glue 3 to foam towards the inner cavity of the dry area pipe beam 101; so that the blocking glue 3 can diffuse in a predetermined direction when foaming, which can reduce or avoid the overflow of the blocking glue 3 when foaming at the periphery of the blocking plate 2, effectively inhibit the escape of the blocking glue 3 when foaming to the outside of the dry area pipe beam 101, improve the foaming quality of the blocking glue 3, meet the sealing requirement of the port of the dry area pipe beam 101, and provide convenient conditions for the subsequent assembly operation of the surrounding parts of the rocker beam 1. Of course, the guide part 201 can also be composed of several sheet structures arranged at the periphery of the blocking plate 2, or have more folded surfaces in contact with the blocking glue 3, and the like, which will not be described here.

[0033] The functional gap is sealed by the sealing filler with bonding function from the outside, so that the blocking glue 3 and the sealing filler are arranged in the dry area pipe beam 101 in a corresponding manner. As shown in Figure 1 and Figure 3 , the blocking plate 2 and the port of the dry area pipe beam 101 are arranged in a clearance fit, which can make the matching of the two more convenient. The setting of the functional gap, on the one hand, meets the tolerance size design of the assembly requirement, and on the other hand, also meets the pressure relief hole of the blocking glue 3, and also serves as a filling area of the sealing filler.

[0034] The sealing filler in the scheme is selected from any sealing glue in the prior art. The sealing glue is filled outside the functional gap, and the step of filling the sealing glue is located after the foaming of the barrier glue 3, so that the barrier plate 2 and the dry area pipe beam 101 are arranged in an inner-outer double-layer sealing structure, improving the sealing performance of the dry area pipe beam 101. Moreover, due to the arrangement structure of the guide part 201 on the barrier plate 2, the filling depth of the sealing glue is deeper, and the sealing reliability is further improved. The functional gap can also be blocked by a sealing strip or other sealing structure to meet the preset sealing requirement, which is not described here.

[0035] The scheme can optimize the structure of the threshold beam 1 by the arrangement of the guide part 201, the barrier glue and the sealing glue on both sides of the barrier plate, so as to meet the air-tight sealing requirement and the waterproof sealing requirement of the end surface of the dry area pipe beam 101.

[0036] In the embodiment, the circumferential direction of the guide part 201 is provided with a plurality of stop blocks for maintaining a functional gap with a preset size. The plurality of stop blocks 205 are integrally arranged with the barrier plate 2 on the outer side wall of the circumferential direction of the guide part, which is beneficial to production and manufacturing, meets the high-precision positioning requirement of the barrier plate 2 on the dry area pipe beam 101 and the maintenance of the functional gap, and overcomes the problem of uneven assembly size gap between the barrier plate 2 and the dry area pipe beam 101.

[0037] In the embodiment, the threshold beam 1 further comprises a wet area pipe beam 102 separated from the dry area pipe beam 101. The wet area pipe beam 102 is located at the bottom of the dry area pipe beam 101, as shown in Figure 1 and Figure 2 The threshold beam 1 is a strip extending in the longitudinal direction, and the longitudinal direction is the length direction of the vehicle. The threshold beam 1 has the dry area pipe beam 101 and the wet area pipe beam 102 separated in the vertical direction. After the threshold beam 1 is assembled on the vehicle, the dry area pipe beam 101 can be close to the dry area of the vehicle, which can improve the expandability of the vehicle modeling and solve the waterproof sealing problem of the threshold beam 1 in the case of high water involvement and long-time immersion. The wet area pipe beam 102 is used for drainage. It should be understood that the barrier plate 2 in the scheme can be directly applied to the threshold beam with sealing requirements in the current prior art, so that the universality of the scheme is stronger, and the existing threshold beam does not need to be modified and designed, saving cost.

[0038] In this embodiment, the functional area for placing the blocking glue 3 and increasing the bonding strength is arranged on the side surface of the blocking plate 2 facing the inside of the dry area pipe beam; the blocking glue 3 is arranged on the blocking plate 2 through the functional area, the functional area is located on the inner side of the guide part 201, the blocking glue 3 is wrapped in the circumferential direction by the guide part 201, and the foaming quality of the blocking glue 3 is further improved. The functional area can be a protrusion or a groove arranged on the inner surface of the blocking plate 2 to increase the bonding area with the blocking glue 3, or a region formed by increasing the roughness of the inner surface of the blocking plate 2 to improve the bonding strength with the blocking glue 3, or other structures that satisfy the improved bonding strength after the blocking glue 3 is arranged on the blocking plate 2, which will not be described here. The above structure enables the blocking glue 3 to be closely connected to the dry area pipe beam 101 port after subsequent coating, baking and foaming, enhances the connection strength between the blocking plate 2 and the dry area pipe beam 101, and reduces the single-sided bonding of the blocking glue 3. The structure of arranging the blocking glue 3 in the functional area of the blocking plate 2 can improve the foaming quality of the blocking glue 3, solve a series of problems that occur after the blocking glue 3 is arranged in the threshold cavity and subsequent coating, baking and foaming, such as poor foaming, single-sided bonding and excessive foaming ratio, improve the waterproof sealing of the internal cavity of the dry area pipe beam 101, and meet the predetermined waterproof requirement.

[0039] In this embodiment, the dry area pipe beam 101 is divided into a plurality of longitudinal through cavities by the partition ribs. Figure 1 and Figure 2 As shown in the drawings, the partition ribs include horizontal partition ribs 103 and vertical partition ribs 104 arranged in the dry area pipe beam 101, the horizontal partition ribs 103 and the vertical partition ribs 104 divide the dry area pipe beam 101 into a plurality of longitudinal cavities; the horizontal partition ribs 103 and the vertical partition ribs 104 are arranged perpendicular to each other, so that the cavities are all rectangular cuboid cavities, which meet the strength requirement of the dry area pipe beam 101; the horizontal partition ribs 103 and the vertical partition ribs 104 also form seats with the periphery of the dry area pipe beam 101 for limiting the assembly of the blocking plate 2, so that the blocking plate 2 is located in the port of the dry area pipe beam 101.

[0040] The functional area is provided with a boss 202 corresponding to each cavity, as shown in the drawings. Figure 7 The boss 202 is formed by the surface of the blocking plate 2 protruding into the cavity of the dry area pipe beam 101, the blocking glue 3 is arranged on the boss 202, and the arrangement of the boss 202 can make the blocking glue 3 further closely connected to the blocking plate 2, thereby meeting the predetermined sealing requirement.

[0041] After the blocking plate 2 is buckled to the port of the dry area pipe beam 101, the blocking glue 3 and the boss 202 are embedded in the corresponding cavities at the same time, and after the blocking glue 3 foams, it can be filled between the inner wall of the corresponding cavity and the side wall of the boss, so as to ensure the sealing of the corresponding cavity of the dry area pipe beam 101, and make the bonding area of the blocking plate 2 and the dry area pipe beam 101 larger through the blocking glue 3, so that the assembly stability and bonding stability of the blocking plate 2 and the dry area pipe beam 101 are more reliable, and the connection strength of the blocking plate 2 on the dry area pipe beam 101 is higher.

[0042] In the embodiment, the blocking glue 3 is divided into a plurality of pieces corresponding to the boss 202, and is arranged around the boss 202 in a wrapping manner. When the blocking glue 3 foams, it can first fill the space between the boss 202 and the corresponding cavity in the circumferential direction, and then expand into the corresponding cavity, so as to ensure the connection tightness of the blocking plate 2 and the dry area pipe beam 101.

[0043] In the embodiment, the blocking plate 2 is integrally formed with a reinforcing rib 203 on the side surface facing the inside of the dry area pipe beam 101, and the reinforcing rib 203 is connected between adjacent bosses 202. The reinforcing rib 203 is designed integrally with the blocking plate 2 and connects the plurality of bosses 202 to each other, so as to strengthen the structure of the blocking plate 2 and further resist the pressure when the blocking glue 3 foams, so that the connection tightness of the blocking plate 2 and the dry area pipe beam 101 after the blocking glue foams is stronger.

[0044] In the embodiment, a plurality of limiting columns 204 for limiting the blocking glue 3 are distributed around the boss 202. As shown in Figure 4 , Figure 7 and Figure 8 , the limiting column 204 is located in the circumferential direction of the boss 202 and close to the boss 202; more accurately, the limiting column 204 is integrally formed on the inner surface of the blocking plate and is a plurality of columns around the boss 202; the blocking glue 3 is limited by the limiting column 204 and is arranged in a wrapping manner around the circumferential direction of the boss 202; each piece of blocking glue 3 is limited by a plurality of limiting columns 204, which further improves the setting stability of the blocking glue 3 on the blocking plate 2 and ensures the bonding strength of the blocking glue and the blocking plate 2 after foaming, so as to improve the waterproof sealing of the dry area pipe beam 101.

[0045] In the embodiment, the blocking plate 2 is fixed to the partition rib by the U-shaped clamp 4, and the blocking plate 2 is provided with a hole for the U-shaped clamp 4 to pass through at the position corresponding to the partition rib; as shown in Figure 9As shown, the U-shaped clamp 4 includes two oppositely arranged clamping parts 401 and a connecting part 402 connecting the two clamping parts 401, the end of the two clamping parts 401 has a close pre-tightening force, so that the U-shaped clamp 4 can be used to fix the blocking plate 2 on the dry area pipe beam 101; and the clamping part 401 is also provided with a anti-disengagement barb 403, further satisfying the connection reliability of the blocking plate 2 on the dry area pipe beam 101. Of course, the blocking plate 2 can also be arranged on the dry area pipe beam 101 in other ways to meet the preset assembly requirements, which will not be repeated here.

[0046] As shown in the Figures 1-3 two U-shaped clamps 4 are diagonally arranged on the dry area pipe beam 101, satisfying the setting requirement of the blocking plate 2 on the dry area pipe beam 101, and also satisfying the positioning requirement of the blocking plate 2 on the dry area pipe beam 101, and the assembly is convenient and reliable.

[0047] The present scheme also discloses a vehicle comprising the aforementioned rocker beam; through the assembly of the blocking plate 2 on the dry area pipe beam 101 with the guiding part 201, cooperating with the blocking glue 3 and the sealing glue sealing the two sides of the blocking plate 2, the structure of the rocker beam 1 can be optimized, satisfying the air-tightness sealing requirement and the waterproof sealing requirement of the end surface of the dry area pipe beam 101.
