[0034] Embodiment 1

[0035] As Figures 1-3 shown, the sealing strip structure of the preferred embodiment of the utility model has the first direction X, the second direction Y and the third direction Z which intersect with each other.

[0036] In some embodiments, the first direction X, the second direction Y and the third direction Z intersect with each other perpendicularly.

[0037] In some embodiments, the sealing strip structure of the embodiment is a strip structure extending along the third direction Z, which is used to be installed at the tail door of the automobile and connected at the head and tail to form a closed annular structure, so as to ensure the sealing property of the trunk of the automobile.

[0038] In some embodiments, the sealing strip structure comprises a buffering unit 10 and a clamping unit 20, and the buffering unit 10 and the clamping unit 20 are connected, wherein the clamping unit 20 is used to clamp the vehicle body, and the buffering unit 10 is used to contact the tail door.

[0039] In some embodiments, the buffering unit 10 and the clamping unit 20 are integrated structures, so as to ensure the sealing property of the whole sealing strip structure.

[0040] In some embodiments, the clamping unit 20 comprises a clamping part 210, and the outer wall of the clamping part 210 is provided with a second extension part 216 extending along the second direction Y; the buffering unit 10 comprises a sealing bubble tube 110, one side edge of the sealing bubble tube 110 is connected with the second extension part 216, and the other side edge is connected with the outer wall of the clamping part 210; the sealing bubble tube 110 and the clamping part 210 form a first cavity 111; the inner wall of the end of the sealing bubble tube 110 away from the clamping part 210 is provided with a protrusion 112 extending towards the first cavity 111, and the protrusion 112 is configured to abut against the second extension part 216 in the second direction Y after the sealing bubble tube 110 is deformed under pressure; by providing the second extension part 216 extending along the second direction Y on the outer wall of the clamping part 210 and connecting one side edge of the sealing bubble tube 110 with the second extension part 216, on the one hand, the second extension part 216 can stably support the whole sealing bubble tube 110, and on the other hand, the protrusion 112 is arranged on the inner wall of the sealing bubble tube 110, so that the sealing bubble tube 110 can abut against the second extension part 216 after being deformed under pressure, and the second extension part 216 supports the protrusion 112, so as to avoid the deformation and collapse of the sealing bubble tube 110 after long-term contact with the tail door, and improve the sealing property.

[0041] In some embodiments, the outer wall of the clamping portion 210 is provided with a first extension 213 extending along the first direction X, the buffer unit 10 comprises a sealing bubble tube 110 and a first lip 120, one end of the first lip 120 is connected with the sealing bubble tube 110, the other end extends to one side of the clamping unit 20, and the first lip 120 is connected with the first extension 213. The outer wall of the clamping portion 210 is provided with a first extension 213 extending along the first direction X, which can support the first lip 120. When pressed, the first lip 120 can be in close contact with the tail box interior panel to achieve sealing. When the pressure is removed, the first lip 120 can deform and reset under the support of the first extension 213, thereby improving the appearance. The first extension 213 can effectively prevent the first lip 120 from collapsing after long-term use.

[0042] In some embodiments, in order to ensure that the clamping portion 210 can be stably and effectively clamped on the vehicle body sheet metal assembly 30, the first lip 120 is arc-shaped, and the concave surface of the first lip 120 faces the clamping portion 210. The curvature of the first extension 213 is matched with that of the first lip 120. The arc-shaped structure of the first lip 120 can make the first lip 120 in close contact with the tail box interior panel to achieve sealing when pressed, further improving the sealing effect of the sealing strip structure.

[0043] In some embodiments, the outer wall of the end of the sealing bubble tube 110 away from the clamping portion 210 is provided with a second lip 113, which can press the sealing bubble tube 110 when the tail door is closed. The second lip 113 can increase the contact area between the sealing bubble tube 110 and the tail door inner panel, thereby improving the sealing performance of the sealing strip structure.

[0044] In some embodiments, the side wall of the sealing bubble tube 110 is provided with an exhaust hole 114, so that the gas in the first chamber 111 can be quickly discharged when the sealing bubble tube 110 is damaged due to excessive internal pressure when the tail door is closed.

[0045] In some embodiments, since the clamping portion 210 itself is a flexible structure, the clamping effect on the sheet metal is limited. Therefore, the clamping unit 20 further comprises a reinforcing framework 220, and the clamping portion 210 is sleeved on the reinforcing framework 220. The reinforcing framework 220 is in an n-shaped structure, and the opening of the reinforcing framework 220 faces away from the buffer unit 10. In this way, by combining the flexibility of the clamping portion 210 with the reinforcing framework 220, the clamping strength of the clamping unit 20 on the sheet metal can be ensured. When installing, the opening of the clamping unit 20 faces the sheet metal and is inserted.

[0046] In some embodiments, the reinforcing framework 220 comprises a main body 221, the main body 221 is provided with a first bridge section 222 and a second bridge section 223 at opposite ends in the first direction X, the first bridge section 222 extends to a side of the clamping portion 210 close to the first lip 120, and the second bridge section 223 extends to a side of the clamping portion 210 away from the first lip 120; wherein the length of the first bridge section 222 in the first direction X is greater than the length of the second bridge section 223 in the first direction X, so that the reinforcing framework 220 forms an asymmetric double-bridge structure, and after the reinforcing framework 220 is integrated with the clamping portion 210, the center point of the reinforcing framework 220 is offset to the right in the first direction X, so that the torque of the sealing strip structure is reduced, the sealing strip structure is easier to rotate and adjust during assembly, and the sealing strip structure will not be deformed, which improves the assembly quality and efficiency, reduces the working pressure and labor time of the assembly workers.

[0047] In some embodiments, the clamping portion 210 is internally formed with a second cavity 211, and the opposite inner walls of the clamping portion 210 are staggered with barbs 212 extending to the second cavity 211, and the barbs 212 are inclined toward the buffer unit 10. The barbs 212 can be used to clamp the flange of the sheet metal, and the barbs 212 are inclined toward the buffer unit 10, so that the barbs 212 are pressed toward the inner sides of the clamping portion 210 during the clamping of the sheet metal into the clamping portion 210, thereby causing the interference fit between the sheet metal and the clamping portion 210, improving the clamping strength therebetween, and when the sheet metal is pulled out, the barbs 212 can limit the sheet metal to a certain extent, thereby avoiding the sealing strip structure from falling off.

[0048] In some embodiments, the ends of the barbs 212 can be provided in a convex point structure, so that the barbs 212 and the sheet metal are switched from surface contact to point contact, which can reduce the insertion force of the sealing strip structure into the sheet metal, effectively improving the assembly quality and efficiency.

[0049] In some embodiments, since the lip in the prior art is generally made of sponge rubber, the sponge rubber is prone to lift the sealing strip and cause the lip to curl after assembly, resulting in the exposure of the sheet metal and the top lining. Therefore, the end of the clamping portion 210 away from the first lip 120 is provided with an outwardly inclined third extension portion 214, the third extension portion 214 is provided with a third lip 230 and a fourth lip 240 at a preset angle with the third lip 230, and the third lip 230 and the fourth lip 240 are respectively arranged on the inner and outer sides of the n-shaped structure. In this way, the clamping stability of the clamping portion 210 and the sheet metal can be effectively improved, thereby improving the stability and reliability of the connection between the sealing strip structure and the vehicle body, and further ensuring the practicability of the sealing strip structure. Moreover, the clamping portion 210 is provided with the outwardly inclined third extension portion 214, which can support and strengthen the third lip 230, so that the third lip 230 always abuts against the surface of the sheet metal, and the clamping portion 210 is not prone to be lifted by the lip after assembly. After the lip is assembled in place, the lip curling phenomenon does not occur, and the assembly quality is improved.

[0050] In some embodiments, the preset angle between the third lip 230 and the fourth lip 240 is 90°-130°, so as to further avoid the lifting or curling phenomenon.

[0051] In some embodiments, in order to improve the sealing effect of the sealing strip structure, the buffer unit 10, the third lip 230 and the fourth lip 240 are all made of flexible sponge rubber, preferably EPDM sponge rubber, and the flexible sponge rubber has good rebounding ability, which can match the gap between the vehicle body sheet metal assembly 30 and the tail door plate 40, and ensure the sealing effect.

[0052] In some embodiments, the clamping portion 210 is made of dense rubber. On the one hand, the clamping portion 210 made of dense rubber can tightly clamp and fasten the clamping portion 210 and the vehicle body sheet metal assembly 30. On the other hand, the clamping portion 210 made of dense rubber can provide strong support for the first extension portion 213, the second extension portion 216 and the third extension portion 214, and compensate for the lost sealing effect of the buffer unit 10, the third lip 230 and the fourth lip 240 in the risk area.

[0053] In some embodiments, in order to improve the stability and reliability of the sealing strip structure during use, the outer wall of the clamping portion 210 away from the first lip 120 is provided with anti-slip lines 215. The anti-slip lines 215 can be composed of a plurality of triangular protruding structures, semicircular protruding structures or other shaped protrusions, etc. As long as they can effectively prevent the generation of slipping or mispositioning during the use of the sealing strip structure, the stability and reliability of the sealing strip structure during use are improved.
