Description

Technical Field

[0001] The present invention relates to the technical field of furniture, and more particularly to a door panel with an anti-falling buckle structure. Background Art

[0002] The door panel includes frame edge strips, corner brackets and door core panels. The specific assembly method is: the four frame edge strips are connected by corner brackets to form a rectangular frame, and then the four side edges of the door core panel are respectively plugged and fixed with the four inner sides of the frame, and finally the assembly is completed.

[0003] When the door core board is a glass core board, the door body, glass core board and molding are currently fixed by nailing and gluing after painting. There are many problems that need to be solved, as follows:

[0004] (1) The nail holes on the surface of the molding are obvious. After being fixed with nails, the nail holes are clearly visible on the surface of the molding, which affects the overall aesthetics of the door panel. In addition, the paint at the nail holes is easy to peel off, exposing the internal structure, reducing the refinement and durability of the product. (2) The molding corners are not tight: there are gaps at the corners, which cannot fit tightly, resulting in uneven edges of the door panel, which not only affects the appearance, but also may accumulate dust and dirt during use, making it difficult to clean, affecting the service life and cleaning and maintenance of the door panel. (3) The corners are prone to cracking: Since the corners are subjected to concentrated force, and the fixing method of nailing and gluing weakens the structural strength of the molding to a certain extent, the corners are prone to cracking during long-term use, especially in environments such as frequent door opening and closing and temperature changes. Phenomenon, seriously affecting the structural stability and service life of the door panel; (4) The assembly of the molding is laborious and inconvenient: the molding is fixed by nailing and gluing, which requires precise manual operation. When nailing, it is necessary to ensure that the nails are driven in vertically and with moderate force, and the glue is applied evenly and in an appropriate amount. The whole process requires high skills of the operator, and the assembly efficiency is low, which is time-consuming and labor-intensive, increasing production costs and labor intensity; (5) The inner corners of the molding need to be manually trimmed to make the right angles at the inner corners of the molding, which is time-consuming and labor-intensive: In order to achieve the ideal right angle effect at the inner corners of the molding, the excess parts need to be manually trimmed. This process not only takes a lot of time and energy, but also it is difficult to ensure the accuracy of the right angles by manual operation, and it is easy to have deviations, affecting the overall quality and aesthetics of the door panel. Therefore, it is a technical problem that needs to be solved in this field.

[0059] Optionally, continue with reference to Figure 2 As shown, the edge banding 2 and buckle 3 can be made of wood-plastic, ABS, or metal. The wood-plastic material, a combination of plastic and wood fiber, is weather-resistant, maintenance-free, environmentally friendly, and highly decorative. The ABS material (acrylonitrile-butadiene-styrene copolymer) is impact-resistant, chemical-resistant, environmentally friendly, and fire- and moisture-resistant. The metal material is durable, scratch- and corrosion-resistant, has high dimensional accuracy, and offers a good texture.

[0060] Compared with the prior art, the door panel with an anti-drop buckle structure provided in this embodiment achieves at least the following beneficial effects:

[0061] First, no nail holes are required on the surface of the edge banding strip 2: a new fixing method is adopted, which completely abandons the traditional nailing process, making the surface of the edge banding strip 2 smooth and flat without any nail hole marks, which greatly improves the overall appearance of the door panel. At the same time, it also avoids problems such as paint peeling at the nail holes and exposure of the internal structure, thereby enhancing the durability of the product.

[0062] Second, by connecting the first sub-edge band 21, the second sub-edge band 22, the third sub-edge band 23 and the fourth sub-edge band 24 through the buckle 3, the first sub-edge band 21, the second sub-edge band 22, the third sub-edge band 23 and the fourth sub-edge band 24 are respectively inserted into the first sub-accommodation space 351 and the second sub-accommodation space 352 of different buckles 3, and there is no need for the first sub-edge band 21, the second sub-edge band 22, the third sub-edge band 23 and the fourth sub-edge band 24 to be tightly fitted in a 45° angle, thereby improving the appearance of the door panel, effectively preventing the accumulation of dust and dirt at the angles, facilitating cleaning and maintenance, and extending the service life of the door panel.

[0063] Third, the assembly of the edge banding 2 is convenient and efficient: The improved assembly process significantly reduces the skill requirements for operators, making the assembly process simple and easy, without the need for complex operating techniques and tools. Operators can quickly and accurately complete the assembly of the edge banding 2, significantly improving production efficiency and reducing labor intensity. It also reduces quality issues caused by improper operation and improves the overall quality of the product.

[0064] Fourth, since the splicing method between the first sub-edge band 21, the second sub-edge band 22, the third sub-edge band 23 and the fourth sub-edge band 24 and the buckle 3 is changed, there is no need to manually cut the inner corners of the edge band 2, saving a lot of time and labor costs.

[0065] In an alternative embodiment, continue to refer to Figure 7-10 As shown, the front plate 31 includes a front plate transition portion 311 and an arc-shaped front plate identification portion 312 connected to the front plate transition portion 311, the front plate identification portion 312 is located on the side of the front plate transition portion 311 away from the middle plate 32, the front plate transition portion 311 is connected to the middle plate 32, and the front plate identification portion 312 protrudes toward the side close to the rear plate 33.

[0069] Specifically, the front panel 31 includes an integrally connected front panel transition portion 311 and a front panel identification portion 312. The front panel transition portion 311 is located between the middle panel 32 and the front panel identification portion 312, that is, along the direction of the middle panel 32 pointing to the front panel 31. One end of the front panel transition portion 311 is connected to the middle panel 32, and the other end is connected to the front panel identification portion 312. The side of the front panel identification portion 312 away from the rear panel 33 can identify the corporate logo, thereby increasing the brand recognition of the product.

[0070] The front plate identification portion 312 can be an arc-shaped plate protruding toward the side close to the rear plate 33. The front plate transition portion 311 includes a first front plate contact portion 3110, a front plate connecting portion 3111, and a second front plate contact portion 3112 connected in sequence along the arc length of the front plate identification portion 312. The first front plate contact portion 3110, the front plate connecting portion 3111, and the second front plate contact portion 3112 can be integrally connected. The front plate connecting portion 3111 can be an isosceles trapezoid. The first front plate contact portion 3110 and the second front plate contact portion 3112 can be trapezoids with chamfers. The first front plate contact portion 311 0 and the chamfer of the second front plate contact portion 3112 are close to the side of the middle plate connection portion 322, and a first obtuse angle α1 is formed between the first front plate contact portion 3110 and the front plate connection portion 3111, and between the second front plate contact portion 3112 and the front plate connection portion 3111 respectively. The angle direction of the first obtuse angle α1 is toward the side away from the rear plate 33, and the first obtuse angle α1 can be 135°. The sum of the first obtuse angle α1 between the first front plate contact portion 3110 and the front plate connection portion 3111 and the first obtuse angle α1 between the second front plate contact portion 3112 and the front plate connection portion 3111 is 270°.

[0071] The middle plate 32 includes a first middle plate contact portion 321, a middle plate connecting portion 322, and a second middle plate contact portion 323 that are integrally connected. The first middle plate contact portion 321 is integrally connected to the first front plate contact portion 3110, the middle plate connecting portion 322 is integrally connected to the front plate connecting portion 3111, and the second middle plate contact portion 323 is integrally connected to the second front plate contact portion 3112. 12 respectively form a second obtuse angle α2, and the angular direction of the second obtuse angle α2 is toward the side of the accommodating space 35; a third obtuse angle α3 is respectively formed between the first middle plate contact portion 321 and the middle plate connecting portion 322, and between the middle plate connecting portion 322 and the second middle plate contact portion 323, and the angular direction of the third obtuse angle α3 is away from the side of the partition piece 34; a third obtuse angle α3 is respectively formed between the first middle plate contact portion 321 and the middle plate connecting portion 322, and between the second middle plate contact portion 323 and the middle plate connecting portion 322, and the angular direction of the third obtuse angle α3 is away from the side of the accommodating space 35.

[0072] The partition member 34 is fixedly connected between the front plate connecting portion 3111 , the front plate identification portion 312 , the middle plate connecting portion 322 and the rear plate 33 .

[0073] A first sub-accommodation space 351 is defined between the first front plate contact portion 3110, the first middle plate contact portion 321, a portion of the rear plate 33 and the partition piece 34, and a second sub-accommodation space 352 is defined between the second front plate contact portion 3112, the second middle plate contact portion 323, a portion of the rear plate 33 and the partition piece 34. The first sub-accommodation space 351 and the second sub-accommodation space 352 are used to accommodate the ends of the first sub-edge sealing strip 21, the second sub-edge sealing strip 22, the third sub-edge sealing strip 23 and the fourth sub-edge sealing strip 24.

[0074] Through the first front panel contact portion 3110, the second front panel contact portion 3112, the first middle panel contact portion 321 and the second middle panel contact portion 323, the force is dispersed to multiple parts of the first sub-edge sealing strip 21, the second sub-edge sealing strip 22, the third sub-edge sealing strip 23 and the fourth sub-edge sealing strip 24, instead of being concentrated on a certain point, thereby effectively reducing local stress concentration and lowering the risk of damage to the door panel body 1 due to external force impact; through the design of the first obtuse angle α1, the second obtuse angle α2 and the third obtuse angle α3, the front panel transition portion 311, the middle panel 32 and the connection between the front panel transition portion 311 and the middle panel 32 are more stable. Compared with right-angle or acute-angle structures, obtuse-angle structures can better disperse stress when subjected to force, reduce stress concentration caused by angles that are too small or too large, and thus improve the stability of the front panel 31 and the middle panel 32; the setting of the first sub-accommodation space 351 and the second sub-accommodation space 352 makes rational use of the internal space of the buckle 3, and hides the two ends of the first sub-edge strip 21, the second sub-edge strip 22, the third sub-edge strip 23 and the fourth sub-edge strip 24 in the first sub-accommodation space 351 and the second sub-accommodation space 352, making the door panel neater and more beautiful in appearance.

[0075] The curved front panel logo portion 312 protrudes toward the side closest to the rear panel 33, increasing the contact area between the front panel 31 and the middle panel 32 to a certain extent, further improving the structural stability. At the same time, the curved structure itself also has a certain buffering effect, which can better adapt to different stress conditions.

[0076] The first front panel contact portion 3110, the front panel connecting portion 3111, and the second front panel contact portion 3112 are all trapezoidal in shape, which provides a more stable contact surface. The lower surfaces of the first and second front panel contact portions 3110, 3112 are closely aligned with the first and second middle panel contact portions 321, 323, respectively. The upper surface of the front panel connecting portion 3111 is closely aligned with the middle panel connecting portion 322, increasing the contact area between the front panel 31 and the middle panel 32 and improving the reliability of the connection.

[0077] In an alternative embodiment, continue to refer to Figure 7-10As shown, the partition member 34 includes a partition portion 341 and a partition connection portion 342 connected to the partition portion 341. The partition connection portion 342 divides the accommodating space 35 into a first sub-accommodating space 351 and a second sub-accommodating space 352. The partition connection portion 342 is rod-shaped. Each vertex corner of the plate groove 12 is respectively inserted with a partition connection portion 342 away from the partition portion 341.

[0078] Along the thickness direction of the door panel body 1, the cross-sectional shape of the partition portion 341 is a chamfered right-angled trapezoid. The chamfered right-angled trapezoid has an upper base edge, a lower base edge, a right-angled side and a beveled side. The upper base edge of the partition is parallel to the lower base edge of the partition. The upper base edge, the right-angled side and the beveled side of the partition are respectively connected to the middle plate connecting portion 322, the rear plate 33, the front plate connecting portion 3111 and the front plate identification portion 312; an L-shaped structure is formed between the lower base edge of the partition and the partition connecting portion 342.

[0079] Specifically, the partition piece 34 includes an integrally connected partition portion 341 and a partition connecting portion 342. Along the thickness direction of the door panel body 1, the cross-sectional shape of the partition portion 341 can be a right-angled trapezoid with a chamfered corner. The right-angled trapezoid with a chamfered corner has a partition upper bottom edge, a partition lower bottom edge, a partition right-angled side and a partition oblique side. The partition upper bottom edge, the partition right-angled side and the partition oblique side of the partition portion 341 are respectively fixedly connected to the middle plate connecting portion 322, the back plate 33, the front plate connecting portion 3111 and the front plate identification portion 312. Specifically, the partition upper bottom edge of the partition part 341 is integrally connected to the middle plate connecting part 322, the partition right-angled side of the partition part 341 is integrally connected to the rear plate 33, and the partition oblique side of the partition part 341 is integrally connected to the front plate connecting part 3111 and the front plate identification part 312; the partition upper bottom edge, the partition right-angled side and the partition oblique side of the partition part 341 can also be welded to the middle plate connecting part 322, the rear plate 33, the front plate connecting part 3111 and the front plate identification part 312 respectively, and the partition connecting part 342 divides the accommodating space 35 into a first sub-accommodating space 351 and a second sub-accommodating space 352, and the volumes of the first sub-accommodating space 351 and the second sub-accommodating space 352 are the same.

[0080] The partition connection part 342 is rod-shaped, and an L-shaped structure is formed between the partition connection part 342 and the lower bottom edge of the partition part 341, and the right angle of the L-shaped structure is toward the front panel identification part 312; each top corner of the plate body groove 12 is respectively inserted with a partition connection part 342 away from the side of the partition part 341; in this embodiment, the specific structure of the partition part 341 includes a first side, a second side, a third side, a fourth side and a fifth side connected in sequence, the first side can be the upper bottom edge of the partition, the fourth side is the lower bottom edge of the partition, the fifth side is the right-angled side of the partition, the first side and the fifth side, the fifth side and the fourth side, and the third side and the fourth side are perpendicular, and the first side and the second side and the second side and the third side form a fourth obtuse angle α4, the first side is connected to the middle plate connection part 322, the second side is connected to the front plate connection part 3111, the third side is connected to the front panel identification part 312, and the fifth side is connected to the back plate 33 corresponding to the front panel identification part 312.

[0081] Using the above solution, the partition's upper bottom edge, right-angled edge, and oblique edge are respectively connected to the middle plate connection portion 322, the rear plate 33, the front plate connection portion 3111, and the front plate identification portion 312. This multi-point connection method can effectively disperse the force, reduce local stress concentration, and improve the stability of the entire clip 3. The partition connection portion 342 in the four clips 3 is rod-shaped and plugs into the top corners of the plate groove 12, further enhancing the firmness of the connection between the clip 3 and the door panel body 1. The partition connection portion 342 divides the storage space 35 into a first sub-storage space 351 and a second sub-storage space 352. This equal division design ensures that the two sub-storage spaces 35 have the same volume, improving space utilization efficiency. The equally divided sub-storage spaces 35 can be used to accommodate the ends of the first sub-edge strip 21, the second sub-edge strip 22, the third sub-edge strip 23, and the fourth sub-edge strip 24, making the door panel more neat.

[0082] The cross-section of the partition portion 341 is a chamfered right-angled trapezoid. The chamfers smooth the corners, reducing stress concentration caused by sharp corners and improving the durability of the buckle 3. The partition connection portion 342 is rod-shaped, which has high bending strength, can effectively withstand external impact, and improve the reliability of the connection.

[0083] The chamfered right-angled trapezoidal cross-section and L-shaped structural design of the partition portion 341 make the entire partition piece 34 more coordinated and beautiful in appearance. The partition connection portion 342 of the four clips 3 is plugged into the top corners of the plate groove 12. This hidden design can reduce the exposed connecting parts, making the door panel surface smoother and neater, and improving the overall aesthetics of the door panel. The plug-in connection between the partition connection portion 342 and the plate groove 12 makes the assembly process of the four clips 3, the first sub-edge strip 21, the second sub-edge strip 22, the third sub-edge strip 23, the fourth sub-edge strip 24, and the door panel body 1 more convenient and quick, reducing assembly time and cost.

[0084] In an alternative embodiment, continue to refer to Figure 7-10 As shown, a first barb 343 is provided on the outer wall of the partition connection portion 342 away from the partition portion 341. Along the thickness direction of the door panel 1, the cross-sectional shape of the first barb 343 is a double inverted J-shape. The first barb 343 protrudes toward the side away from the central axis of the partition connection portion 342. The first barb 343 is placed in the top corner of the plate body groove 12. The double inverted J-shaped cross-sectional shape is a hook-like structure. The double inverted J-shaped cross-sectional shape can not only provide better gripping force and anti-loosening effect, but also can better disperse stress when subjected to force, reducing structural damage caused by external force impact. With this solution, the first barb 343 can be better embedded in the top corner of the plate body groove 12 through the first barb 343, providing a stronger gripping force, which can prevent the partition connection portion 342 from loosening from the plate body groove 12 and improve the reliability of the connection. Protruding the first barb 343 toward the side away from the central axis of the partition connection portion 342 can increase the contact area between the first barb 343 and the plate groove 12, further improving the stability of the connection.

[0085] In an alternative embodiment, combining Figure 2 、 Figure 12-15 As shown, Figure 15 This is a cross-sectional view of the first, second, third, or fourth sub-edge bands in an edge band provided by the present invention. In this embodiment, the direction from the edge band body 210 to the plug-in portion 211 is such that the plug-in portion 211 includes a plug-in connection section 2111, a plug-in barb 2112, and a plug-in slope 2113 connected in sequence. The plug-in connection section 2111 is connected to the edge band body 210 on the side away from the plug-in barb 2112.

[0086] The cross-sectional shape of the plug-in connecting section 2111 along the thickness direction of the door panel body 1 is rectangular. Along the thickness direction of the door panel body 1, a second barb 21121 and a third barb 21122 are respectively provided on opposite sides of the plug-in barb portion 2112. The cross-sectional shapes of the second barb 21121 and the third barb 21122 are both lightning-shaped. Along the thickness direction of the door panel body 1, the orthographic projection of the second barb 21121 partially overlaps with the orthographic projection of the third barb 21122. The second barb 21121 is located on the side of the third barb 21122 close to the plug-in connecting section 2111.

[0087] The cross-sectional shape of the plug-in slope portion 2113 along the thickness direction of the door panel body 1 is an isosceles trapezoid, which includes parallel upper slope bases and lower slope bases. Along the thickness direction of the door panel body 1, the length of the upper slope base is smaller than the length of the lower slope base, and the upper slope base is located on the side of the lower slope base away from the plug-in barb portion 2112.

[0088] Specifically, along the direction of the edge sealing body 210 pointing to the plug-in portion 211, one end of the plug-in barb portion 2112 is integrally connected to the plug-in connecting section 2111, and the other end is integrally connected to the plug-in slope portion 2113. The end of the plug-in connecting section 2111 away from the plug-in barb portion 2112 is integrally connected to the edge sealing body 210, and the plug-in slope portion 2113 is designed as a slope to facilitate the insertion of the first sub-edge sealing strip 21, the second sub-edge sealing strip 22, the third sub-edge sealing strip 23 and the fourth sub-edge sealing strip 24 into the plate body groove 12; the cross-sectional shape of the above-mentioned plug-in connecting section 2111 along the thickness direction of the door panel body 1 can be a rectangle, and the long side of the plug-in connecting section 2111 corresponds to the edge sealing body 210.

[0089] Along the thickness direction of the door panel 1, the second barb 21121 and the third barb 21122 are respectively provided on opposite sides of the plug-in barb portion 2112. The cross-sectional shapes of the second barb 21121 and the third barb 21122 are both lightning-shaped (such as ), the lightning shape extends along the edge sealing body 210 in the direction of the plug-in portion 211; along the thickness direction of the door panel body 1, the orthographic projection of the second barb 21121 partially overlaps with the orthographic projection of the third barb 21122, the second barb 21121 is located on the side of the third barb 21122 close to the plug-in connection section 2111, and the third barb 21122 is located on the side of the second barb 21121 close to the plug-in slope 2113; the cross-sectional shape of the plug-in slope 2113 along the thickness direction of the door panel body 1 is an isosceles trapezoid, and the isosceles trapezoid includes parallel upper and lower bases of the slope, and along the thickness direction of the door panel body 1, the length of the upper base of the slope is less than the length of the lower base of the slope, the lower base of the slope is close to the side of the plug-in barb 2112, and the upper base of the slope is away from the side of the plug-in barb 2112.

[0090] The cross-sectional shape of the second barb 21121 and the third barb 21122 are both "lightning-shaped", which can increase the friction between the plug-in portion 211 and the door panel body 1 and prevent the plug-in portion 2111 from loosening or falling off during use. The orthographic projection of the second barb 21121 partially overlaps with the orthographic projection of the third barb 21122, thereby enhancing the interaction between the second barb 21121 and the third barb 21122 and improving the overall stability. The cross-sectional shape of the plug-in connection section 2111 along the thickness direction of the door panel body 1 is a rectangle, which has high bending strength and torsional strength and can effectively withstand various forces that may be generated during use. The cross-sectional shape of the plug-in slope portion 2113 is an isosceles trapezoid, which can disperse stress and avoid stress concentration, thereby improving the overall strength of the first sub-edge seal 21, the second sub-edge seal 22, the third sub-edge seal 23 and the fourth sub-edge seal 24. The length of the upper bottom edge of the slope of the plug-in sloped portion 2113 is less than the length of the lower bottom edge of the slope, making the plug-in portion 211 smoother when inserted into the door panel body 1, reducing resistance during installation and improving installation convenience. The second barb 21121 is located on the side of the third barb 21122 close to the plug-in connection section 2111, so that during the insertion process, the third barb 21122 first contacts the door panel body 1 to perform a preliminary positioning function, and then the second barb 21121 is further fixed to ensure stable installation of the plug-in portion 211. The design of the second barb 21121, the third barb 21122 and the sloped portion allows the plug-in portion 211 to fit tightly with the door panel body 1, reducing gaps, thereby improving sealing performance and preventing dust, moisture, etc. from entering the interior.

[0091] In an alternative embodiment, continue to refer to Figure 12 As shown, along the thickness direction of the door panel body 1, the other side of the plug-in barb portion 2112 corresponding to the third barb 21122 is the first plane, and the other side of the plug-in barb portion 2112 corresponding to the second barb 21121 is the second plane; along the direction of the edge sealing body 210 pointing to the plug-in portion 211, the side where the plug-in connecting section 2111 is connected to the second plane is the third plane; along the thickness direction of the door panel body 1, the distance a between the first plane and the third plane is greater than the distance b of the plate groove 12, and a fifth obtuse angle is formed between the second plane and the third barb 21122.

[0092] The second plane and the third plane are on the same horizontal plane, the first plane and the second plane are respectively parallel to the third plane, and a fifth obtuse angle is formed between the side of the third barb 21122 close to the plug-in connection section 2111 and the second plane.

[0093] By providing the first, second, and third planes, the contact area and points between the connector 211 and the door panel 1 are increased, thereby improving the stability of the connection. The third barb 21122 and the second barb 21121 correspond to the first and second planes, respectively. The second and third planes are connected and located on the same horizontal plane, facilitating an interference fit between the connector 211 and the panel groove 12, further enhancing the stability of the connection. The fifth obtuse angle formed between the second plane and the third barb 21122 guides the connector 211 into the panel groove 12, reducing resistance and friction during installation and improving installation precision and convenience.

[0094] The arrangement of the first, second, and third planes can also disperse stress and avoid stress concentration, thereby improving the overall strength of the structure. The coordination of the second barb 21121 and the third barb 21122 with the first, second, and third planes not only further enhances the bending and torsion resistance of the structure and improves the bearing capacity of the plug-in portion 211, but also allows the plug-in portion 211 to fit tightly with the door panel 1, reducing gaps, thereby improving sealing performance and preventing dust, moisture, etc. from entering the interior.

[0095] In an alternative embodiment, continue to refer to Figure 2 、 Figure 12-15 As shown, along the direction of the edge sealing body 210 pointing to the plug-in portion 211, the edge sealing body 210 includes an edge sealing glass contact portion 2101, an edge sealing glue flow portion 2102 and an edge sealing connection portion 2103 connected in sequence, and the edge sealing connection portion 2103 is connected to the plug-in connection section 2111;

[0096] Along the thickness direction of the door panel body 1, the cross-sectional shape of the edge-sealing glass contact portion 2101 is a right-angled trapezoid, and the edge-sealing glue flow portion 2102 includes a first glue flow segment 21021 and a second glue flow segment 21022 relative to each other. The second glue flow segment 21022 is located on the side of the first glue flow segment 21021 close to the core panel 4. The second glue flow segment 21022 includes a first glue flow branch 21022a and a second glue flow branch 21022b connected to the first glue flow branch 21022a. The first glue flow branch 21022a is connected to the edge-sealing glass contact portion 2101, and the second glue flow branch 21022b is connected to the edge-sealing connection portion 2103. The angle between the first glue flow branch 21022a and the second glue flow branch 21022b is the sixth obtuse angle α6.

[0097] Specifically, along the direction of the edge sealing body 210 pointing to the plug-in part 211, one end of the edge sealing glue flow part 2102 is integrally connected to the edge sealing glass contact part 2101, and the other end is integrally connected to the edge sealing connection part 2103, and the edge sealing connection part 2103 is integrally connected to the plug-in connection section 2111.

[0098] Along the thickness direction of the door panel body 1, the cross-sectional shape of the edge-sealing glass contact portion 2101 is a right-angled trapezoid, and the straight edges of the right-angled trapezoid are in direct contact with the glass chip. The edge-sealing glue flow portion 2102 includes a first glue flow segment 21021 and a second glue flow segment 21022 relative to each other. The first glue flow segment 21021 and the second glue flow segment 21022 are respectively V-shaped structures. The angles between the V-shaped structure of the first glue flow segment 21021 and the V-shaped structure of the second glue flow segment 21022 can be respectively a sixth obtuse angle α6. The sixth obtuse angle α6 of the V-shaped structure in the first glue flow segment 21021 and the V-shaped structure in the second glue flow segment 21022 are toward the side of the glass core board; along the thickness direction of the door panel body 1, the sixth obtuse angle α6 of the V-shaped structure in the first glue flow segment 21021 and the sixth obtuse angle α6 of the V-shaped structure in the second glue flow segment 21022 do not overlap at all.

[0099] The second glue flow section 21022 is located on the side of the first glue flow section 21021 close to the core board 4. The second glue flow section 21022 includes a first glue flow branch 21022a and a second glue flow branch 21022b that are integrally connected. The first glue flow branch 21022a is connected to the edge-sealing glass contact part 2101, and the second glue flow branch 21022b is connected to the edge-sealing connection part 2103. The angle between the first glue flow branch 21022a and the second glue flow branch 21022b is the sixth obtuse angle α6. Subsequently, glue is applied to the first glue flow branch 21022a and the second glue flow branch 21022b away from the first glue flow section 21021. The glue can be glass glue, structural glue and nail-free glue.

[0100] This solution not only ensures a stable connection between the edge seal body 210 and the plug-in connection section 2111, but also provides a larger contact area, enhancing the stability of the fit with the glass and reducing the risk of loosening and falling off. It also guides the smooth flow of glue, reducing resistance and friction during installation, and further improving sealing performance. Furthermore, by optimizing the structural design of the edge seal body 210, stress concentration points are reduced, improving the durability of the first, second, third, and fourth sub-edge seals 21, 22, 23, and 24, thereby extending the product's service life.

[0101] In an alternative embodiment, continue to refer to Figure 2 、 Figure 12-16 As shown, Figure 16It is a cross-sectional view of a portion of the edge sealing body of the first sub-edge sealing strip, the second sub-edge sealing strip, the third sub-edge sealing strip, or the fourth sub-edge sealing strip in an edge sealing strip provided by the present invention; in this embodiment, the edge sealing connection portion 2103 includes a first edge sealing connection segment 21130, a second edge sealing connection segment 21131, a third edge sealing connection segment 21132, a fourth edge sealing connection segment 21133, a fifth edge sealing connection segment 21134, and a sixth edge sealing connection segment 21135, which are connected in sequence. The first edge sealing connection segment 21130 is connected to a portion of the first glue flow segment 21021 and are located on the same horizontal plane, and the sixth edge sealing connection segment 21135 is connected to the third plane of the plug-in connection segment 2111 and is located on the same horizontal plane.

[0102] The first edge sealing connecting section 21130 and the second edge sealing connecting section 21131, the second edge sealing connecting section 21131 and the third edge sealing connecting section 21132, and the third edge sealing connecting section 21132 and the fourth edge sealing connecting section 21133 are perpendicular; the fourth edge sealing connecting section 21133 and the fifth edge sealing connecting section 21134, and the fifth edge sealing connecting section 21134 and the sixth edge sealing connecting section 21135 form a seventh obtuse angle α7.

[0103] Specifically, the edge connection portion 2103 includes a first edge connection segment 21130, a second edge connection segment 21131, a third edge connection segment 21132, a fourth edge connection segment 21133, a fifth edge connection segment 21134 and a sixth edge connection segment 21135 that are connected in an integral manner. The first edge connection segment 21130, the second edge connection segment 21131, the third edge connection segment 21132, the fourth edge connection segment 21133 and the sixth edge connection segment 21135 are straight line segments, the fifth edge connection segment 21134 is a slant line segment, and the first edge connection segment 21130 It is integrally connected to the side of the first glue flow section 21021 away from the edge-sealing glass contact portion 2101, and the first edge-sealing connection section 21130 and the side of the first glue flow section 21021 away from the edge-sealing glass contact portion 2101 are located on the same horizontal plane, the sixth edge-sealing connection section 21135 is integrally connected to the third plane of the plug-in connection section 2111 on the side away from the fifth edge-sealing connection section 21134, and the third plane of the sixth edge-sealing connection section 21135 and the plug-in connection section 2111 are located on the same horizontal plane, ensuring that the edge-sealing connection section 2103 can be accurately aligned during the installation process to reduce installation errors.

[0104] A 90° angle is formed between the first edge sealing connection section 21130 and the second edge sealing connection section 21131, between the second edge sealing connection section 21131 and the third edge sealing connection section 21132, and between the third edge sealing connection section 21132 and the fourth edge sealing connection section 21133; a seventh obtuse angle α7 is formed between the fourth edge sealing connection section 21133 and the fifth edge sealing connection section 21134, and between the fifth edge sealing connection section 21134 and the sixth edge sealing connection section 21135, because the seventh obtuse angle α7 is formed between the fourth edge sealing connection section 21133 and the fifth edge sealing connection section 21134, and between the fifth edge sealing connection section 21134 and the sixth edge sealing connection section 21135.

[0105] The above solution utilizes a multi-segment connection design to smoothly transition cross-sectional changes and reduce sudden changes. The first and second edge-sealing connection segments 21130 and 21131, the second and third edge-sealing connection segments 21131 and 21132, and the third and fourth edge-sealing connection segments 21132 and 21133 are perpendicular to each other, allowing for gradual changes in cross-sectional shape to avoid sudden changes. A seventh obtuse angle, α7, is defined between the fourth and fifth edge-sealing connection segments 21133 and 21134, and between the fifth and sixth edge-sealing connection segments 21134 and 21135. This seventh obtuse angle, α7, smoothly transitions stress and reduces stress concentration, thereby improving the durability of the structure and extending the product's service life.

[0106] Optionally, continue with reference to Figure 2 、 Figure 7-10 As shown, the depth range of the first sub-accommodating space 351 and the second sub-accommodating space 352 along the thickness direction of the door panel body 1 is 6.5mm~6.7mm. For example, the depth of the first sub-accommodating space 351 and the second sub-accommodating space 352 along the thickness direction of the door panel body 1 can be 6.5mm, 6.6mm or 6.7mm.

[0107] If the width of the middle plate 32 along the arc length direction of the rear plate 33 is too large, there will be gaps between the first sub-edge strip 21, the second sub-edge strip 22, the third sub-edge strip 23 and the fourth sub-edge strip 24 and the corresponding buckles 3; if the width of the middle plate 32 along the arc length direction of the rear plate 33 is too small, the first sub-edge strip 21, the second sub-edge strip 22, the third sub-edge strip 23 and the fourth sub-edge strip 24 will fit too tightly with the corresponding buckles 3, making it inconvenient to install. Therefore, continue to refer to Figure 2 、 Figure 7-10As shown, in this embodiment, the width of the intermediate plate 32 along the arc length direction of the rear plate 33 can range from 7.9 mm to 8.1 mm. This not only minimizes gaps between the first, second, third, and fourth sub-edge sealing strips 21, 22, 23, and 24 and the corresponding buckles 3, but also prevents excessive tightness between the first, second, third, and fourth sub-edge sealing strips 21, 22, 23, and 24 and the corresponding buckles 3. The width of the intermediate plate 32 along the arc length direction of the rear plate 33 can be 7.9 mm, 8.0 mm, or 8.1 mm.

[0108] It can be seen from the above embodiments that the door panel with the anti-drop buckle structure provided by the present invention achieves at least the following beneficial effects:

[0109] First, the surface of the sealing strips requires no nail holes: A new fixing method completely eliminates the traditional nailing process, resulting in a smooth and flat surface without any nail hole marks, greatly improving the overall aesthetics of the door panel. It also avoids problems such as paint peeling and internal structure exposure at the nail holes, thereby enhancing the product's durability. Second, by connecting the first, second, third, and fourth sub-edge bands through angle brackets, the first, second, third, and fourth sub-edge bands can be inserted into the first and second sub-receiving spaces of different angle brackets, eliminating the need for the first, second, third, and fourth sub-edge bands to fit tightly together at 45° angles. This improves the appearance of the door panel and effectively prevents the accumulation of dust and dirt at the joints, facilitating cleaning and maintenance, and extending the service life of the door panel. Third, the sealing strips are easy and convenient to assemble: The improved assembly process significantly reduces the operator's skill requirements, making the assembly process simple and easy, without the need for complex operating techniques and tools. Operators can quickly and accurately complete the assembly of the packaging strips, significantly improving production efficiency and reducing labor intensity. This also reduces quality issues caused by improper operation and improves the overall quality of the product. Fourthly, by changing the splicing method between the first, second, third, and fourth sub-edge banding strips and the corner brackets, the internal corners of the packaging strips do not need to be manually squared, saving a lot of time and labor costs.

[0110] Although some specific embodiments of the present invention have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present invention. It should be understood by those skilled in the art that modifications may be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
