[0050] The inventor found that the conventional installation method using plug-in fasteners (such as buckles) to achieve locking in the inside-out direction is prone to looseness due to manufacturing and assembly errors, as the door gap strip itself has a certain structural strength. In addition, these fasteners may become loose after a period of use due to material aging, structural loosening, and other reasons. Furthermore, due to the limitations of the installation structure, it is difficult to place the above-mentioned fasteners on the lower end surface of the door gap strip, resulting in ineffective compression of the lower end by the fasteners. In addition, the lower end of the door gap strip is more prone to scratches, bumps, and other situations, making the lower end of the door gap strip more prone to looseness.

[0051] To effectively solve the problem of looseness of the lower end of the door gap strip, please refer to Figures 1 to 19 , the column door gap strip mounting structure provided by the present application will be described. The column door gap strip mounting structure comprises a main plate 1, an auxiliary plate 2, a first limiting body 3 and a door gap strip 4. The main plate 1 has a main plate flange 110 extending upward and downward, the auxiliary plate 2 is arranged on the outer side of the main plate 1 and covers at least the lower part of the main plate 1, and the auxiliary plate 2 has an auxiliary plate flange 210 corresponding to the main plate flange 110. The first limiting body 3 is located between the main plate flange 110 and the auxiliary plate flange 210 and is connected with one of the main plate flange 110 and the auxiliary plate flange 210, and the first limiting body 3 cooperates with the other one of the main plate flange 110 and the auxiliary plate flange 210 to form a limiting space 5. The door gap strip 4 is installed on the main plate flange 110, and the lower side of the door gap strip 4 is provided with a hanging table 6, the hanging table 6 is arranged in the limiting space 5 and is in contact with the lower surface of the first limiting body 3, and the side wall of the limiting space 5 limits the displacement of the hanging table 6 in the inside-out direction and the front-back direction.

[0052] In the embodiment, the main plate 1 is an outer panel of a vehicle door, the auxiliary plate 2 can be a reinforcing plate, a decorative plate or the like arranged on the outer side of the main plate 1, and can play other auxiliary roles relative to the main plate 1. The auxiliary plate 2 can cover only the lower region of the main plate 1 or can cover the upper region of the main plate 1, and the specific function of the auxiliary plate 2 determines whether the auxiliary plate 2 covers the lower region or the upper region of the main plate 1. The material of the auxiliary plate 2 includes but is not limited to metal and plastic.

[0053] The application scenarios of the embodiment include but are not limited to the two vehicle doors corresponding to the B pillar. The specific pillar corresponding to the embodiment is determined by the specific vehicle model, the door opening and closing mode and the actual decoration requirement. For example, if the door gap strip 4 is arranged on the rear side edge of the front door, the door gap strip 4 is abutted and adapted to the front side edge of the rear door. This arrangement is suitable for the conventional door opening mode, the opposite door opening mode or other door opening modes. If the door gap strip 4 is arranged on the front side edge of the rear door, the door gap strip 4 is abutted and adapted to the rear side edge of the front door. This arrangement is suitable for the conventional door opening mode, the opposite door opening mode or other door opening modes.

[0054] In the embodiment, if the first limiting body 3 is arranged on the main plate flange 110, a limiting space 5 is formed between the first limiting body 3 and the auxiliary plate flange 210 (as shown in FIG. 4). Figure 10 If the first limiting body 3 is arranged on the auxiliary plate flange 210, a limiting space 5 is formed between the first limiting body 3 and the main plate flange 110 (as shown in FIG. 5). Figure 7 Figure 11 Preferably, the limiting space 5 is preferably circumferentially arranged around the hanging table 6, so as to effectively limit the hanging table 6 from the front and rear directions and the inner and outer directions through the cooperation of the first limiting body 3 and the hanging table 6, and provide a larger limiting contact area for the hanging table 6.

[0055] It should be further noted that the implementation mode of the hanging table 6 includes but is not limited to a rubber member, a silica gel member and the like, and needs to meet the assembly strength requirement and preferably has a certain elastic deformation capability. Based on this, in order to improve the positioning reliability of the hanging table 6, the hanging table 6 can be closely attached to the side wall of the limiting space 5. This assembly mode is suitable for the hanging table 6 having a certain elasticity, and avoids the problem of extrusion damage caused by the rigid abutment of the hanging table 6 and the side wall of the limiting space 5. In the case of allowing, a certain gap can be reserved. This assembly mode is not only suitable for the hanging table 6 having a certain elasticity, but also suitable for the case where the hanging table 6 is a rigid member. The embodiment exemplarily shows that the hanging table 6 is attached to the first limiting body 3, but has a gap of 0.2mm to 0.4mm (for example, 0.3mm) between the other side wall of the limiting space 5 (for example, the side wall formed by the main plate flange 110).

[0056] ​In this embodiment, the specific implementation of the hanging table 6 is that the hanging table 6 comprises a side wall part 610 and a bottom part 620 which are integrally formed, the side wall part 610 is connected to the bottom end of the door gap strip 4 and has at least two limiting walls which are arranged at an angle between adjacent two limiting walls, and the bottom part 620 is arranged at the bottom of the side wall part 610 and is in hanging contact with the lower surface of the first limiting body 3. The side wall part 610 and the door gap strip 4 can be directly connected or indirectly connected through other components. On this basis, the specific arrangement of the bottom part 620 includes but is not limited to the following several kinds: 1) having one bottom part 620 which is only in hanging contact with the lower surface of the first limiting body 3; 2) having a plurality of bottom parts 620 which are spaced apart in the up-down direction, and a clamping space capable of accommodating one first limiting body 3 is formed between adjacent two bottom parts 620, so that the first limiting body 3 can be clamped by adjacent two bottom parts 620 in the up-down direction, thereby enhancing the limiting effect in the up-down direction.

[0057] For the above arrangement 2), the following layout modes can also be formed:

[0058] 2-1) The clamping space and the first limiting body 3 can correspond one by one, that is, the bottom part 620 is arranged in multiple in the up-down direction. For example, if the first limiting body 3 is provided with one, the bottom part 620 is provided with two, and a clamping space is formed between the two bottom parts 620; if the first limiting body 3 is arranged in two in the up-down direction, the bottom part 620 is provided with three, and a clamping space is formed between adjacent two bottom parts 620, and two first limiting bodies 3 are clamped by the three bottom parts 620. It should be understood that this layout mode is realized based on that the number of the first limiting body 3 is N and the number of the bottom part 620 is (N+1), N is an integer greater than or equal to 1.

[0059] 2-2) The number of the first limiting body 3 is less than the number of the clamping space (for example, the clamping space has three, and the first limiting body 3 is provided with one), and a height adjustment allowance is formed between the clamping space and the first limiting body 3, so that the first limiting body 3 can be selectively inserted into the corresponding clamping space according to different assembly requirements, and the flexibility is stronger.

[0060] 2-3) The first limiting body 3 and the bottom part 620 are arranged one by one, and each bottom part 620 is in hanging contact with the lower surface of the corresponding first limiting body 3. On this premise, if the bottom part 620 and the first limiting body 3 are both provided with two, the first limiting body 3 at the top has no corresponding clamping space, and the first limiting body 3 at the bottom can be inserted into the corresponding clamping space; the rest of the number of layout is also similar in principle, which will not be listed one by one here.

[0061] Based on the structure of the above-mentioned mounting platform 6, in this embodiment, the specific implementation methods of the limiting space 5 are not limited to the following: 1) The first limiting body 3 is set on the auxiliary plate flange 210 and forms an L-shaped limiting space 5 with the main plate flange 110 (such as Figure 7 As shown), the cross section of the side panel 610 is also L-shaped and has two limiting walls; 2) the first limiting body 3 is provided on the auxiliary plate flange 210, and a C-shaped limiting space 5 is formed between the first limiting body 3 and the main plate flange 110, and between the first limiting body 3 and the auxiliary plate flange 210 (as shown). Figure 11 As shown), the cross section of the side member 610 is also C-shaped and has three limiting walls; 3) The first limiting body 3 is provided on the main plate flange 110 and forms an L-shaped limiting space 5 with the auxiliary plate flange 210 (as shown Figure 10 As shown in the figure), the cross section of the side frame member 610 at this time is also L-shaped, and has two limiting walls; 4) the first limiting body 3 is arranged on the main board flange 110, and a C-shaped limiting space 5 is formed between the first limiting body 3 and the main board flange 110, and between the first limiting body 3 and the auxiliary board flange 210 (not shown in the figure). The cross section of the side frame member 610 at this time is also C-shaped, and has three limiting walls.

[0062] In this embodiment, the upper and lower lengths of the hanging platform 6 can be 8mm to 15mm (for example, 10mm, 11mm, 12mm, 13mm, 14mm). By reasonably setting the size of the hanging platform 6, the space utilization rate can be improved while ensuring assembly reliability.

[0063] In this embodiment, the first position-limiting member 3 may also be in a block, spherical, or plate-like configuration. A plate-like member is preferred, specifically a position-limiting rib with a surface substantially perpendicular to the vertical direction. By configuring the first position-limiting member 3 in a plate-like shape, the vertical dimension of the first position-limiting member 3 is minimized, preventing the first position-limiting member 3 from excessively encroaching upon the space between the main panel 1 and the auxiliary panel 2, thereby ensuring that the door seam strip 4 has sufficient length.

[0064] Compared with the prior art, the mounting structure of the vertical column door gap strip provided by the embodiment realizes the hanging in the up-down direction through the abutment of the hanging table 6 and the bottom surface of the first limiting body 3, and then realizes the limiting of the bottom of the door gap strip 4 in the up-down direction; the limiting of the bottom of the door gap strip 4 in the front-back direction and the inside-outside direction is realized through the limiting of the hanging table 6 in the front-back direction and the inside-outside direction by the limiting space 5, and the displacement of the hanging table 6 relative to the main plate 1 in the front-back direction and the inside-outside direction is effectively limited, thereby realizing the limiting of the bottom of the door gap strip 4 in the front-back direction and the inside-outside direction. Through the cooperation of the hanging table 6, the first limiting body 3 and the limiting space 5, the lower end of the door gap strip 4 can be effectively limited in the up-down direction, the front-back direction and the inside-outside direction, and the limiting mode is directly provided by the main plate 1, the auxiliary plate 2 and the first limiting body 3, without the need for fasteners for fixing, thereby ensuring the stability of the cooperation between the lower end of the door gap strip 4 and the main plate 1 and the auxiliary plate 2, and avoiding the problem of loosening of the lower end of the door gap strip 4.

[0065] In some specific embodiments of the auxiliary plate flange 210, the auxiliary plate flange 210 includes a third edge 211 and a fourth edge 212, the edge of the main body of the auxiliary plate 2 is extended in the front-back direction to form the third edge 211, and the edge of the third edge 211 is bent inward to form the fourth edge 212. If the first limiting body 3 is connected to the auxiliary plate flange 210, the first limiting body 3 is arranged between the third edge 211 and the fourth edge 212. The included angle between the third edge 211 and the fourth edge 212 is not less than 90°, which avoids the difficulty in arranging the side wall 610 of the hanging table 6 and the first limiting body 3 and the problem of difficult assembly; at the same time, the included angle between the third edge 211 and the fourth edge 212 is not greater than 100°, which avoids the problem that the extension angle of the auxiliary plate flange 210 is too large to affect the external light and the limiting reliability of the limiting space 5.

[0066] In order to facilitate the installation of the auxiliary plate 2, a larger installation space is provided for the main body of the auxiliary plate 2 in the front-back direction, and in some more specific embodiments, the auxiliary plate flange 210 further includes a fifth edge 213, the edge of the main body of the auxiliary plate 2 is bent inward to form the fifth edge 213, and the edge of the fifth edge 213 is extended in the front-back direction to form the third edge 211. The third edge 211, the fourth edge 212 and the fifth edge 213 cooperate to form a stepped structure at the edge of the auxiliary plate 2, the main body of the auxiliary plate 2 is supported by the stepped structure, the main body of the auxiliary plate 2 is effectively spaced from the main plate 1, and sufficient spacing space is ensured between the main plate 1 and the auxiliary plate 2.

[0067] On the basis of the fifth edge 213, a reinforcing rib (i.e. Figure 12The triangular plate structure is arranged below the first limiting body 3, so as to enhance the structural strength of the third edge 211 and the fourth edge 212, avoid the cracking of the third edge 211 and the fourth edge 212 at the intersection area, and facilitate the structural stability of the edge of the auxiliary plate 2. In a specific implementation, a plurality of reinforcing ribs are arranged in the up-down direction to comprehensively cover the reinforcing effect.

[0068] More specifically, the reinforcing rib is a triangular plate structure, that is, one edge of the triangular plate structure is connected with the third edge 211, another edge is connected with the fourth edge 212, and the remaining one edge is arranged between the third edge 211 and the fourth edge 212. Due to the triangular design of the reinforcing rib, the reinforcing rib itself has high structural strength, which is conducive to enhancing the reinforcing effect between the third edge 211 and the fourth edge 212. Meanwhile, by adopting the plate structure design, the size of the reinforcing rib in the up-down direction is compressed, the number of reinforcing ribs is increased to meet the reinforcing requirement, and the raw material can be saved.

[0069] Referring to Figures 3 to 11 In some embodiments, the lower end of the door gap strip 4 is connected with a lower corner 7, the lower corner 7 is installed on the main plate flange 110, and the hanging table 6 is arranged at the lower end of the lower corner 7. The outer edge of the lower corner 7 is provided with a first lip 710 extending towards the main plate flange 110, and the first lip 710 is in close abutment with the main plate flange 110. The side of the outer edge of the lower corner 7 away from the first lip 710 is provided with a second lip 720, and the second lip 720 is used to abut against the edge of the adjacent door. The outer side of the second lip 720 forms the decorative surface of the lower corner 7. The lower corner 7 and the hanging table 6 are preferably integrally formed to reduce the joint therebetween. The hardness of the lower corner 7 is lower than that of the door gap strip 4, and the lower corner 7 can not be provided with a metal core to enhance the deformability of the lower corner 7, ensure that the lower corner 7 changes with the change of the shape of the main plate 1, and ensure the convenience and reliability of the installation of the lower corner 7 on the lower part of the main plate 1. The lower corner 7 and the door gap strip 4 can be connected by secondary injection molding, adhesion or the like. The purpose of the lower corner 7 is mainly to form a transition connection relationship between the door gap strip 4 and the hanging table 6. On the premise that the first lip 710 ensures the sealing between the door gap strip 4 and the main plate 1, the lower corner 7 enhances the bonding strength with the main plate flange 110 to avoid the tearing of the root of the hanging table 6 due to the hanging force of the hanging table 6.

[0070] On the basis of the above embodiments, the second lip 720 is arranged in a spaced manner with the auxiliary plate flange 210 to avoid interference caused by the auxiliary plate 2 during installation and affect the installation progress. Specifically, the spacing between the two can be 0.2mm-0.4mm (for example, 0.3mm).

[0071] In some specific embodiments of the lower corner 7, in order to realize the assembly of the lower corner 7 and the main plate flange 110, the lower corner 7 has a lower clamping groove 701, the lower clamping groove 701 is clamped in interference with the main plate flange 110, one side wall of the lower clamping groove 701 is provided with a lower boss 730, the lower boss 730 is tightly abutted to the main plate flange 110, after installation, the lower boss 730 and the side wall not provided with the lower boss 730 are tightly abutted to the main plate flange 110. By means of interference clamping, combined with the limiting cooperation relationship of the hanging table 6, the limiting space 5 and the first limiting body 3, not only good sealing is realized, but also the lower corner 7 can be firmly positioned on the main plate flange 110 under the premise of not using buckles and other fasteners, the installation structure is simpler, and the problem of shaking is less likely to occur; by providing the lower boss 730, the contact area of the main plate flange 110 and the side wall of the clamping groove is reduced, on the one hand, it is ensured that the lower boss 730 can be tightly abutted to realize positioning, and on the other hand, friction noise in the forming process can be reduced. In specific implementation, the main plate flange 110 includes a first edge 111 bent inward, and a second edge 112 bent away from the main plate 1 and located at the inner edge of the first edge 111, the lower clamping groove 701 is clamped in interference with the second edge 112; in addition, the inner and outer widths of the lower clamping groove 701 can be 2mm-2.5mm (for example, 2.2mm, 2.3mm).

[0072] On the basis of the above-mentioned embodiments, in order to further simplify the structure of the lower corner 7, a lower avoiding space 702 corresponding to the second lip 720 is arranged on the outer side of the lower corner 7, from Figure 8 The cross section of the lower corner 7 is roughly S-shaped from the perspective. After the door is closed, the lower corner 7 is compressed, and the S-shaped cross section structure enables the lower corner 7 itself to better adapt to the compression requirement, and after the door is opened, the compression amount is more easily released, so as to return to the free state, the lower corner 7 can better maintain the stability of its own structure in the repeated opening and closing process, and irreversible elastic deformation is less likely to occur, and the service life is longer; at the same time, the structure of the lower corner 7 is simpler, the manufacturing is more convenient, and the use cost can also be correspondingly reduced.

[0073] In some specific embodiments of the lower boss 730, a plurality of lower bosses 730 are arranged in the up-down direction, each of the lower bosses 730 extends in a direction perpendicular to the up-down direction, as Figure 4 By reasonably arranging the number of lower bosses 730, the fitting area of the lower boss 730 as a whole and the main plate flange 110 is ensured as much as possible, and the reliability of clamping is ensured.

[0074] Referring to Figures 13 to 19In some embodiments, the main plate flange 110 includes a first edge 111 bent inwardly, and a second edge 112 bent away from the main plate 1 at the inner edge of the first edge 111; the stile door strip mounting structure further includes an upper corner 8, the upper corner 8 has an upper clamping groove 801, the upper clamping groove 801 is clamped in interference with the second edge 112; the side of the upper corner 8 facing the main plate 1 is further provided with a limiting ear 810, and the limiting ear 810 and the upper corner 8 form an auxiliary clamping groove 802 accommodating the first edge 111, at least one side wall of the auxiliary clamping groove 802 is in close contact with the first edge 111. Wherein, the upper corner 8 is located on the inner side of the main plate 1, avoiding affecting the appearance; the hardness of the upper corner 8 is lower than that of the door strip 4, and the metal core can not be arranged inside the upper corner 8, thereby enhancing the deformability of the upper corner 8 and ensuring the convenience and reliability of the installation on the upper part of the main plate 1; the connection between the upper corner 8 and the door strip 4 can be realized by secondary injection molding or bonding. The upper corner 8 is installed with the second edge 112 through the clamping groove clamping mode, and the limiting ear 810 cooperates with the lower corner 7 to limit the first edge 111 in the front and rear directions, thereby realizing the effective positioning of the upper corner 8 and avoiding the problem of falling off after installation. Without using fasteners such as buckles, the upper part of the door strip 4 can be firmly positioned on the main plate flange 110, the mounting structure is simpler, and the upper end of the door strip 4 is avoided from being loose like the lower end.

[0075] In some specific embodiments, in the inner-outer direction, the cross-sectional area of the limiting ear 810 gradually increases in the direction close to the main plate 1, and the outer side of the limiting ear 810 abuts against the inner side of the main plate 1, thereby further increasing the assembly bonding strength in the inner-outer direction.

[0076] On the basis of the above-mentioned embodiments, referring to Figure 15 and Figure 16 the top of the upper corner 8 has a second limiting body 820, the second limiting body 820 abuts against the upper end surface of the first edge 111 to further limit the displacement of the upper corner 8 in the up-down direction, thereby ensuring the reliability of the assembly. It should be noted that the limiting ear 810 is arranged close to the top of the upper corner 8, and the second limiting body 820 is directly located at the top of the upper corner 8, both of which have the possibility of being exposed, so the top surfaces of the limiting ear 810 and the second limiting body 820 are designed as smooth planes, curved surfaces or other outward display surface types.

[0077] In some embodiments, the auxiliary card slot 802 is provided with an upper boss 830 adjacent to the area of the door gap strip 4, the upper boss 830 is located on at least one side wall of the auxiliary card slot 802, and after installation, the upper boss 830 and the side wall without the upper boss 830 are tightly abutted with the second edge 112 in the inner and outer directions. By providing the upper boss 830, the contact area between the main plate flange 110 and the side wall of the card slot is reduced, which on the one hand ensures that it can be tightly abutted with the upper boss 830 to ensure the reliability of positioning and sealing, and on the other hand can also reduce the friction noise in the forming process. In specific implementation, the thickness of the upper boss 830 can be 0.2mm-0.4mm (for example, 0.3mm).

[0078] In some embodiments, the outer edge of the upper corner 8 is provided with a third lip 840 extending towards the first edge 111, and the third lip 840 is tightly abutted with the first edge 111; the side of the outer edge of the lower corner 7 away from the third lip 840 is provided with a fourth lip 850, and the fourth lip 850 is abutted with the edge of the adjacent door. Among them, the upper corner 8 has an upper avoidance space 803 corresponding to the fourth lip 850, and the cross section of the upper corner 8 is approximately S-shaped. After the door is closed, the upper corner 8 is compressed, and the S-shaped cross-sectional structure enables the upper corner 8 itself to better adapt to the compression requirement, and after the door is opened, the compression amount is more easily released, thereby returning to a free state. The upper corner 8 can better maintain the stability of its own structure in the repeated opening and closing process, and is not easy to deform irreversibly, so the service life is longer; at the same time, the structure of the upper corner 8 is simpler, the manufacturing is more convenient, and the use cost can also be correspondingly reduced.

[0079] In specific implementation, the third lip 840 and the limiting lobe 810 have a certain gap therebetween, which can be 1mm-1.5mm (for example, 1.2mm, 1.3mm), and the gap is related to the thickness of the main plate 1. After installation, the third lip 840 and the limiting lobe 810 are tightly abutted with the first edge 111 to achieve effective limiting in the front and rear directions.

[0080] In some embodiments, the top end of the door gap strip 4 forms a first stepped surface 401, and the lower part of the upper corner 8 forms a second stepped surface 804 connected with the first stepped surface 401. The combination between the door gap strip 4 and the upper corner 8 through the stepped surface increases the combination area between the upper corner 8 and the door gap strip 4, directly improving the combination strength; at the same time, the design of the stepped surface also makes the force bearing direction between the upper corner 8 and the door gap strip 4 more diversified, which can not only bear the force in the upward and downward directions, but also bear the force in the inner and outer directions, effectively avoiding the problem that the combination surface is easy to fall off after being subjected to shearing force due to single combination surface.

[0081] In specific implementation, referring to Figure 14 and Figure 19, the first stepped surface 401 is a two-order stepped surface, and the corners of the first stepped surface 401 are all connected through a round corner, and correspondingly, the second stepped surface 804 is also a two-order stepped surface, and the corners of the second stepped surface 804 are all connected through a round corner. The first stepped surface 401 and the second stepped surface 804 cooperatively form a Z-shaped joint structure, which not only meets the requirement of the bonding strength, but also has a simple setting mode, and is beneficial to reducing the manufacturing cost.

[0082] In some embodiments, the inner edge of the opening end of the auxiliary card slot 802 is outwardly folded to form an interface limiting edge 860, as shown in the figure. Figures 13 to 18 As shown in the figure, the interface limiting edge 860 can be partially overlapped with the first edge 111 in the front-rear direction to achieve front-rear limiting and enhance the reliability of installation.

[0083] In some specific embodiments of the door gap strip 4, as shown in the figure, Figure 19 the door gap strip 4 has a main body card slot 402 clamped with the second edge 112, a main body avoiding space is formed on the outer side of the main body card slot 402, the outer edge of the door gap strip 4 is provided with a fifth lip 410 extending towards the first edge 111, and the fifth lip 410 is tightly abutted with the first edge 111; the side of the outer edge of the door gap strip 4 away from the fifth lip 410 is provided with a sixth lip 420, and the sixth lip 420 is abutted with the edge of the adjacent door and can also play a role of shielding the gap. In the embodiment, the door gap strip 4 itself has a high structural strength by setting a metal core made of aluminum or other materials in the region where the main body card slot 402 is located, the main body card slot 402 can achieve high-strength clamping positioning of the second edge 112, and the use of fasteners such as buckles is avoided, so that the installation structure is simple, the upper and lower ends of the door gap strip 4 are effectively limited through the cooperation of the upper interface 8 and the lower interface 7, and the door gap strip 4 as a whole can be effectively fixed on the main plate flange 110. At the same time, the fifth lip 410 and the sixth lip 420 respectively realize abutment sealing with the main plate flange 110 and the adjacent door, and the structure is simple and can guarantee the sealing effect.

[0084] On the basis of the above-mentioned embodiments, in order to further simplify the structure of the door gap strip 4, a main body avoiding space corresponding to the sixth lip 420 is arranged on the outer side of the door gap strip 4, as viewed from the perspective of the figure, Figure 19 the cross section of the door gap strip 4 is roughly S-shaped extending in the inner-outer direction. After the door is closed, the door gap strip 4 is compressed, and the S-shaped cross section structure makes the door gap strip 4 itself better adapt to the compression requirement, and after the door is opened, the compression amount is more easily released, so as to return to the free state, and the door gap strip 4 can better maintain the stability of its own structure in the repeated opening and closing process, and is not easy to be irreversibly elastically deformed, so that the service life is longer; at the same time, the structure of the door gap strip 4 is simpler, the manufacturing is more convenient, and the use cost can also be correspondingly reduced.

[0085] It should be noted that the first lip 710, the fifth lip 410 and the third lip 840 are sequentially connected from bottom to top to ensure the sealing of the abutment with the main plate 1 (specifically the first edge 111); the second lip 720, the sixth lip 420 and the fourth lip 850 are sequentially connected from bottom to top to ensure the sealing of the abutment with the adjacent door, and form a continuous and smooth decorative surface. In addition, the door gap strip 4 is regularly or irregularly shaped along the extension path of the main plate flange 110, and the design of the door gap strip 4 in the figure is irregularly arc-shaped.
