[0026] In one embodiment, such as Figure 2 As shown, the first strip 7 includes a first shaping section 71 and a first compression section 72; one end of the first shaping section 71 is connected to one side wall of the third corner 5, and the other end abuts against the first corner 3 through the first compression section 72.

[0027] In this embodiment, the first strip 7 is connected to the side wall of the third corner 5 through the first shaping section 71, and abuts against the first corner 3 through the first compression section 72 to facilitate sealing. The first shaping section 71 mainly serves to support the first compression section 72, while the first compression section 72 deforms by abutting against the first corner 3 to ensure sealing performance.

[0028] In one embodiment, such as Figure 2 As shown, the first compression section 72 has a first extension 73 with an arc-shaped structure, which is used to abut against the first corner 3. One end of the first extension 73 is connected to the first compression section 72, and the other end is suspended and set at a preset angle with the first compression section 72.

[0029] In this embodiment, by providing a first extension 73 on the first compression section 72 to abut against the first corner 3, since one end of the first extension 73 is suspended, the deformation is increased when abutting against the first corner 3, thereby improving the sealing effect.

[0030] Specifically, such as Figure 2 As shown, the first extension 73 abuts against the bend of the first corner 3 to improve the sealing effect.

[0031] Specifically, such as Figure 2 As shown, the first extension 73 and the first compression section 72 are made of the same material and are integrally formed.

[0032] In one embodiment, such as Figure 2As shown, the first shaping segment 71 is bonded to the third corner 5 by the first adhesive 75.

[0033] In this embodiment, the first shaping segment 71 is connected to the third corner 5 by adhesive bonding, which is convenient and quick.

[0034] In one embodiment, such as Figure 2 As shown, the side of the first shaping section 71 extends to the first adhesive 75 and is provided with a first decorative corner 74, which is used to cover the first adhesive 75 through the first decorative corner 74.

[0035] In this embodiment, a first decorative corner 74 is provided on the side of the first shaping section 71 so as to cover the first adhesive 75 after bonding with the first adhesive 75, thereby improving the overall aesthetics.

[0036] In one embodiment, such as Figure 3 As shown, the second strip 8 includes a second shaping section 81, a second compression section 82, and a third compression section 83; the second shaping section 81 is connected to the second corner 4; the two sides of the second shaping section 81 extend a predetermined distance along the two side walls of the second corner 4, and the two sides of the second shaping section 81 are respectively provided with the second compression section 82 and the third compression section 83 facing the door panel 2; the second compression section 82 abuts against one side wall of the fourth corner 6; the bend of the fourth corner 6 abuts against the third compression section 83.

[0037] In this embodiment, the second shaping section 81 extends a predetermined distance along the two side walls of the second corner 4 on both sides, and a second compression section 82 and a third compression section 83 are respectively provided at the extensions on both sides, so that when the door panel 2 is closed, the second compression section 82 abuts against one side wall of the fourth corner 6, and the bend of the fourth corner 6 abuts against the third compression section 83. The second shaping section 81 plays a supporting role, while the second compression section 82 and the third compression section 83 deform in cooperation with the fourth corner 6 to achieve multiple seals and improve the sealing effect.

[0038] In one embodiment, such as Figure 3 As shown, the second compression section 82 is provided with a second extension 84, which abuts against the other side wall of the fourth corner 6, and the second shaping section 81 is bonded to the second corner 4 by the second adhesive 85.

[0039] In this embodiment, by adding a second extension 84, the second extension 84 abuts against the other side wall of the fourth corner 6, further improving the sealing performance. At the same time, by providing a second decorative corner 86 on the side of the second shaping section 81, the second adhesive 85 is covered after bonding with the second adhesive 85, improving the overall aesthetics.

[0040] Specifically, such as Figure 3As shown, the second extension 84 and the third compression section 83 are made of the same material and are integrally formed.

[0041] Specifically, such as Figure 1 As shown, the first corner 3, the second corner 4, the third corner 5, and the fourth corner 6 are all right angles.

[0042] In one embodiment, such as Figures 4 to 6 As shown, the second leather strip 8 includes a first sub-leather strip 9 and a second sub-leather strip 10. The first sub-leather strip 9 is disposed on the side wall of the second corner 4 near the first corner 3, and the second sub-leather strip 10 is disposed on the side wall of the second corner 4 away from the first corner 3.

[0043] In this embodiment, the second leather strip 8 is composed of a first sub-leather strip 9 and a second sub-leather strip 10. The first sub-leather strip 9 and the second sub-leather strip 10 form two seals on the two side walls of the second corner 4, respectively. When the door panel 2 and the fixing part 1 are closed, the first sub-leather strip 9 and the second sub-leather strip 10 abut against the two side walls of the fourth corner 6 to seal, thereby further improving the sealing performance.

[0044] In one embodiment, such as Figure 5 As shown, the first sub-strip 9 includes a third shaping section 91 and a fourth compression section 92. The third shaping section 91 is embedded in the side wall of the second corner 4; the fourth compression section 92 is connected to the third shaping section 91 and is used to abut against the side wall of the fourth corner 6.

[0045] It should be noted that the side wall of the second corner 4 is provided with a groove for embedding the third shaping section 91.

[0046] In this embodiment, during connection, the third shaping section 91 is embedded in the side wall of the second corner 4 to facilitate installation and disassembly, and provides support for the fourth compression section 92 and keeps the fourth compression section 92 in a predetermined shape. When the door panel 2 and the fixing part 1 are closed, the side wall of the fourth corner 6 abuts against the fourth compression section 92, causing the fourth compression section 92 to be compressed and deformed to achieve a seal.

[0047] Specifically, the cross-section of the fourth compression section 92 is semi-circular, which improves structural stability and thus extends service life.

[0048] Specifically, the third shaping section 91 and the fourth compression section 92 are integrally formed to improve the overall structural strength.

[0049] In one embodiment, such as Figure 6As shown, the second sub-strip 10 includes a fourth shaping section 101, a third extension 102, and a fourth extension 103. The fourth shaping section 101 is bonded to the side wall of the second corner 4 by a third adhesive 11. The fourth shaping section 101 is provided with a plurality of third extensions 102 at intervals on the side facing the fourth corner 6, for abutting against the side wall of the fourth corner 6 through the third extensions 102. One end of the fourth extension 103 is connected to the end of the fourth shaping section 101 away from the second corner 4, and the other end extends to the outer side of the periphery of the side wall of the second corner 4, for abutting against the side wall of the fourth corner 6. The periphery of the side wall of the second corner 4 is bent to form a protrusion 12 on the side facing the fourth shaping section 101. A limiting groove 13 adapted to the protrusion 12 is formed between the fourth extension 103 and the fourth shaping section 101.

[0050] In this embodiment, the fourth shaping segment 101 is bonded to the side wall of the second corner 4 using the third adhesive 11 to provide support for the third extension 102 and the fourth extension 103. Simultaneously, multiple third extensions 102 are provided on the fourth shaping segment 101; the number of third extensions 102 can be two or more, selected according to actual needs. This allows the third extensions 102 to abut against the side wall of the fourth corner 6, compressing and deforming to achieve a seal. Furthermore, a fourth extension 103 is provided at the end of the fourth shaping segment 101, allowing the fourth extension 103 to extend to the outer periphery of the side wall of the second corner 4, thereby enabling… The fourth extension 103 has greater elasticity, providing sufficient space for adaptation when the door body has slight deformation or large gaps, ensuring sealing and flexibility. In addition, the limiting groove 13 cooperates with the protrusion 12 for limiting or positioning during installation, and can also cover the third adhesive 11, further improving the overall stability and sealing. The third extension 102 and the fourth extension 103 work together with the first strip 7 to achieve multiple seals, which can not only increase the sealing effect, but also adhere to the side wall of the fixing part 1 or the door panel part 2 from different planes. Even if there are production errors in the door body, it can still ensure contact on other planes to achieve a sealing effect.

[0051] Specifically, the fourth shaping section 101, the third extension 102, and the fourth extension 103 are integrally formed to improve the overall structural strength.

[0052] The specific working principle of the enhanced airtightness leather strip structure provided in this embodiment is as follows: When the door panel 2 is in the closed state, the first corner 3 and the third corner 5 are adapted to approach each other and maintain a certain gap, so that the first corner 3 abuts against the first compression section 72 of the first leather strip 7, so that the first compression section 72 deforms and fits tightly against the first corner 3; at the same time, the second corner 4 and the fourth corner 6 are adapted to approach each other and maintain a certain gap, so that the bend of the fourth corner 6 abuts against the third compression section 83, so that the third compression section 83 deforms and fits tightly against the fourth corner 6; in addition, the second compression section 82 and the second extension 84 They respectively abut against the two side walls of the fourth corner 6, and deform to fit tightly against the two side walls of the fourth corner 6; or, the fourth compression section 92, the third extension 102 and the fourth extension 103 form multiple seals abut against the two side walls of the fourth corner 6 to form multiple seals, thereby improving the overall sealing performance through multiple seals to meet the airtightness requirements of the door; in specific applications, they can be applied to the connection of other opening and closing structures that require sealing, such as car doors, gates or windows, to improve sealing performance and solve the problem that the existing rubber strip structure is simple and has poor airtightness, making it difficult to meet the airtightness requirements of the door.
