Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and more specifically, to a door panel with an anti-detachment buckle structure. Background Technology

[0002] The door panel, including the frame strips, corner brackets, and door core panel, is assembled as follows: the four frame strips are connected by corner brackets to form a rectangular frame, and then the four sides of the door core panel are inserted and fixed to the four inner sides of the frame, and finally the assembly is completed.

[0003] When the door core panel is made of glass, the current installation process for the door panel, glass core panel, and molding strip involves painting followed by nailing and gluing for fixation. This method presents several problems that urgently need to be addressed, as follows:

[0004] (1) The nail holes on the surface of the molding strip are obvious. After nailing, the nail holes are clearly visible on the surface of the molding strip, which affects the overall aesthetics of the door panel. Moreover, the paint at the nail holes is easy to peel off, exposing the internal structure and reducing the product's refinement and durability. (2) The corners of the molding strip are not tight: There are gaps at the corners, which cannot be tightly fitted, resulting in uneven edges of the door panel. This not only affects the appearance but may also accumulate dust and dirt during use, making it difficult to clean and affecting the service life and cleaning and maintenance of the door panel. (3) The corners are prone to cracking: Due to the concentrated force at the corners and the nailing and gluing fixing method, the structural strength of the molding strip is weakened to a certain extent. During long-term use, especially in environments with frequent door opening and closing and temperature changes, the corners are prone to cracking. The phenomenon seriously affects the structural stability and service life of the door panel; (4) The assembly of the strip is laborious and inconvenient: The strip is fixed by nailing and gluing, which requires precise manual operation. When nailing, it is necessary to ensure that the nail is driven in vertically and with moderate force. The glue should also be applied evenly and in appropriate amount. The whole process requires high skill from the operator, resulting in low assembly efficiency, time and labor, and increased production costs and labor intensity; (5) The corner of the strip needs to be manually trimmed to achieve a right angle, which is time and laborious: In order to achieve the ideal right angle effect at the corner of the strip, it is necessary to manually trim the excess part. This process not only requires a lot of time and energy, but also makes it difficult to ensure the accuracy of the right angle by manual operation, which is prone to deviation and affects the overall quality and aesthetics of the door panel. Therefore, it is a technical problem that urgently needs to be solved in this field.

[0005] Chinese patent document (application number: 2016205788472, application date: 2016.06.13) discloses an aluminum alloy door frame, see [link to patent document]. Figure 1 As shown, Figure 1This is a schematic diagram of the overall appearance of an aluminum alloy door frame provided in Chinese patent literature. The aluminum alloy door frame includes a polygonal door frame body, polygonal pressure strips and polygonal buffer strips corresponding to the door frame body. The door frame body is formed by multiple trapezoidal frame edges 11' connected end to end and fixed by corner brackets 12' / 13' / 14' and screws 15'. The frame edges 11' are made of extruded aluminum profiles and include corner bracket mating parts, pressure strip mating parts and core plate mating parts arranged from the outside to the inside. The corner bracket mating parts, pressure strip mating parts and core plate mating parts are arranged from left to right. In this design, the corner brackets 12' / 13' / 14' are respectively inserted into the adjacent frame edges 11. During assembly, the adjacent pressure strips still form a 45° angle, which does not solve the above-mentioned technical problem. Utility Model Content

[0006] In view of this, the present invention provides a door panel with an anti-detachment buckle structure to solve the problems of obvious nail holes on the surface of the pressure strip, loose joints of the pressure strip, and easy cracking at the joints in the prior art.

[0007] This application provides a door panel with an anti-detachment latch structure, including a door panel body, an edge banding strip, and latches, wherein...

[0008] The door panel has a core board hole that penetrates the door panel along its thickness direction. The door panel has a groove around the periphery of the core board hole that is recessed toward the geometric center away from the core board hole.

[0009] The edge banding strip includes a first sub-edge banding strip, a second sub-edge banding strip, a third sub-edge banding strip, and a fourth sub-edge banding strip. The first sub-edge banding strip is parallel to the third sub-edge banding strip, the second sub-edge banding strip is parallel to the fourth sub-edge banding strip, and the first sub-edge banding strip is perpendicular to the second sub-edge banding strip.

[0010] The first, second, third, and fourth sub-edge banding strips each include an insertion part that connects the edge banding body to the edge banding body. The insertion part is located on the side of the edge banding body facing the groove of the panel. The insertion part is strip-shaped. The insertion parts of the first, second, third, and fourth sub-edge banding strips are respectively inserted into the groove of the panel. Along the thickness direction of the door panel, the orthographic projection of the edge banding body and the orthographic projection of the groove of the panel do not overlap at all. The thickness of the insertion part is less than the thickness of the edge banding body.

[0011] The buckles are located between the first and second sub-edge bands, between the second and third sub-edge bands, between the third and fourth sub-edge bands, and between the fourth and first sub-edge bands. Each buckle includes a front panel, a middle panel, an arc-shaped back panel, and a partition. The front and back panels are arranged opposite each other, and the side of the back panel away from the front panel contacts the core panel. The front panel is integrally connected to the back panel through the middle panel. The back panel protrudes towards the front panel, and a receiving space is formed between the front panel, the middle panel, and the back panel. The openings of the receiving space face the top corners of the panel grooves. The partition is an L-shaped structure. The partition is located in the receiving space and divides the receiving space into a first sub-receiving space and a second sub-receiving space. The first sub-receiving space and the second sub-receiving space are parallel along the arc length direction of the back panel.

[0012] Each of the top corners of the groove in the panel is fitted with a partition. The side of the first sub-edge band near the second sub-edge band and the side of the second sub-edge band near the first sub-edge band, the side of the second sub-edge band near the third sub-edge band and the side of the third sub-edge band near the second sub-edge band, the side of the third sub-edge band near the fourth sub-edge band and the side of the fourth sub-edge band near the third sub-edge band, and the side of the fourth sub-edge band near the first sub-edge band and the side of the first sub-edge band near the fourth sub-edge band are respectively fitted into the first sub-accommodating space and the second sub-accommodating space.

[0013] Compared with the prior art, the door panel with anti-detachment buckle structure provided by this utility model achieves at least the following beneficial effects:

[0014] First, the sealing strip surface requires no nail holes: Adopting a completely new fixing method, it eliminates the traditional nailing process, resulting in a smooth and flat surface without any nail hole marks. This greatly enhances the overall aesthetics of the door panel and avoids problems such as paint peeling and exposure of internal structures at nail holes, thus increasing product durability. Second, by connecting the first, second, third, and fourth sub-edge banding strips with corner brackets, each strip is inserted into the first and second receiving spaces of different corner brackets. This eliminates the need for a tight 45° angled fit between the strips, improving the door panel's appearance and effectively preventing dust and dirt accumulation at the corners, facilitating cleaning and maintenance, and extending the door panel's lifespan. Third, the sealing strip assembly is convenient and efficient: The improved assembly process significantly reduces the skill requirements for operators. The assembly process is simple and easy, requiring no complex operating skills or tools. Operators can quickly and accurately complete the assembly of the sealing strips, significantly improving production efficiency, reducing labor intensity, and also reducing quality problems caused by improper operation, thus improving the overall quality of the product. Fourth, because the splicing method between the first, second, third, and fourth sub-edge sealing strips and the corner code has been changed, there is no need to manually chisel right angles at the inside corners of the sealing strips, saving a lot of time and labor costs.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all the technical effects described above at the same time.

The shape of the door panel body 1 can be rectangular, the edge banding strip 2 can be a rectangular structure, and each of the top corners of the rectangular structure is a notch. The buckle 3 can be an irregular shape.

[0046] A core board hole 11 is provided at the geometric center of the door panel 1. In this embodiment, the core board hole 11 is rectangular in shape. Depending on the actual situation, the core board hole 11 can also be designed in other shapes, and this embodiment does not impose any specific limitations on this. The opening area of ​​the core board hole 11 is smaller than the area of ​​the door panel 1.

[0047] Combination Figure 2 and Figure 5 As shown, the door panel 1 has a panel groove 12 that is recessed toward the geometric center away from the core panel hole 11 around its periphery. The panel groove 12 can also be a rectangular groove for inserting the edge banding strip 2 and the buckle 3. The rectangular groove has four corner grooves, and the buckles 3 are inserted into the four corner grooves respectively.

[0048] There are notches between the first sub-edge banding strip 21 and the second sub-edge banding strip 22, between the second sub-edge banding strip 22 and the third sub-edge banding strip 23, between the third sub-edge banding strip 23 and the fourth sub-edge banding strip 24, and between the fourth sub-edge banding strip 24 and the first sub-edge banding strip 21.

[0053] The front panel 31 and the rear panel 33 are arranged opposite each other. The side of the rear panel 33 away from the front panel 31 contacts the core panel 4. The core panel 4 can be a glass core panel. The core panel hole 11 corresponds to the front part of the door panel body 1, and the core panel 4 is installed between the edge sealing body 210 and the shaped line 5. The front panel 31 is integrally connected to the rear panel 33 through the middle panel 32. Since the front panel 31, the middle panel 32 and the rear panel 33 are designed to be integrally connected, the stability of the first sub-clasp, the second sub-clasp, the third sub-clasp and the fourth sub-clasp are improved.

[0054] The aforementioned rear panel 33 can be an arc-shaped panel protruding from the front panel 31. Along the thickness direction of the door panel body 1, the cross-sectional shape of the front panel 31 is approximately V-shaped, and the opening of the V-shape faces the middle panel 32.

[0055] The openings of the accommodating spaces 35 in the first, second, third, and fourth sub-clamps are respectively oriented toward the four apex corners of the plate groove 12. The partition 34 is fixedly connected to the accommodating space 35 and divides the accommodating space 35 into the first sub-accommodating space 351 and the second sub-accommodating space 352.

[0061] First, the surface of the edge banding strip 2 requires no nail holes: Adopting a completely new fixing method, it abandons the traditional nailing process, resulting in a smooth and flat surface without any nail hole marks. This greatly enhances the overall aesthetics of the door panel and avoids problems such as paint peeling and exposure of the internal structure at nail holes, thus increasing the product's durability. Second, the first sub-edge banding strip 21, the second sub-edge banding strip 22, the third sub-edge banding strip 23, and the fourth sub-edge banding strip 24 are connected by clips 3. These strips are inserted into the first and second receiving spaces 351 and 352 of the clips 3, respectively. This eliminates the need for a tight 45° corner fit between the strips, improving the door panel's appearance and effectively preventing dust and dirt accumulation at the corners, facilitating cleaning and maintenance, and extending the door panel's lifespan. Third, the assembly of edge banding strip 2 is convenient and efficient: the improved assembly process significantly reduces the skill requirements for operators. The assembly process is simple and easy to perform, requiring no complicated operating skills or tools. Operators can quickly and accurately complete the assembly of edge banding strip 2, significantly improving production efficiency, reducing labor intensity, and also reducing quality problems caused by improper operation, thus improving the overall quality of the product. Fourth, because the splicing method between the first sub-edge banding strip 21, the second sub-edge banding strip 22, the third sub-edge banding strip 23, and the fourth sub-edge banding strip 24 and the buckle 3 has been changed, the inside corners of edge banding strip 2 no longer need to be manually trimmed to a right angle, saving a lot of time and labor costs.

[0062] In one alternative embodiment, continue to refer to Figures 7-10 As shown, the front panel 31 includes a front panel transition portion 311 and an arc-shaped front panel marking portion 312 connected to the front panel transition portion 311. The front panel marking portion 312 is located on the side of the front panel transition portion 311 away from the middle panel 32. The front panel transition portion 311 is connected to the middle panel 32. The front panel marking portion 312 protrudes towards the side closer to the rear panel 33. The front panel transition portion 311 includes a first front panel contact portion 3110, a front panel connecting portion 3111, and a second front panel contact portion 3112 connected sequentially along the arc length of the front panel marking portion 312. The shapes of the first front panel contact portion 3110, the front panel connecting portion 3111, and the second front panel contact portion 3112 are trapezoidal. The first front panel contact portion 3110 and the front panel connecting portion 3111, and the second front panel contact portion 3112 and the front panel connecting portion 3111, respectively form a first obtuse angle α1. The angle direction of the first obtuse angle α1 is towards the side away from the rear panel 33.

[0063] The intermediate plate 32 includes a first intermediate plate contact portion 321, an intermediate plate connecting portion 322, and a second intermediate plate contact portion 323 connected in sequence. The first intermediate plate contact portion 321 is connected to the first front plate contact portion 3110, the intermediate plate connecting portion 322 is connected to the front plate connecting portion 3111, and the second intermediate plate contact portion 323 is connected to the second front plate contact portion 3112. The first intermediate plate contact portion 321 and the first front plate contact portion 3110, the intermediate plate connecting portion 322 and the front plate connecting portion 3111, and the second intermediate plate contact portion 323 and the second front plate contact portion 3112 respectively form a second obtuse angle α2, and the angle direction of the second obtuse angle α2 is towards the receiving space 35. The first intermediate plate contact portion 321 and the intermediate plate connecting portion 322, and the intermediate plate connecting portion 322 and the second intermediate plate contact portion 323 respectively form a third obtuse angle α3, and the angle direction of the third obtuse angle α3 is away from the partition member 34.

[0064] The partition 34 is positioned between the front panel connecting part 3111, the middle panel connecting part 322, and the rear panel 33;

[0065] The first front plate contact portion 3110, the first middle plate contact portion 321, a portion of the rear plate 33 and the partition member 34 form a first sub-accommodating space 351, and the second front plate contact portion 3112, the second middle plate contact portion 323, a portion of the rear plate 33 and the partition member 34 form a second sub-accommodating space 352.

[0066] Specifically, the front panel 31 includes an integrally connected front panel transition portion 311 and a front panel logo portion 312. The front panel transition portion 311 is located between the middle panel 32 and the front panel logo portion 312, that is, in the direction from the middle panel 32 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 logo portion 312. The front panel logo portion 312 can display the company logo on the side away from the rear panel 33, thereby increasing the product brand recognition.

[0067] The front panel marking portion 312 can be an arc-shaped plate protruding towards the rear panel 33. The front panel transition portion 311 includes a first front panel contact portion 3110, a front panel connecting portion 3111, and a second front panel contact portion 3112 connected sequentially along the arc length of the front panel marking portion 312. The first front panel contact portion 3110, the front panel connecting portion 3111, and the second front panel contact portion 3112 can be integrally connected. The front panel connecting portion 3111 can be an isosceles trapezoid. The first front panel contact portion 3110 and the second front panel contact portion 3112 can be trapezoids with chamfers. The chamfer of the first front plate contact portion 3110 and the second front plate contact portion 3112 is close to the middle plate connecting portion 322. The first obtuse angle α1 is formed between the first front plate contact portion 3110 and the front plate connecting portion 3111, and between the second front plate contact portion 3112 and the front plate connecting portion 3111. The angle direction of the first obtuse angle α1 is towards the side away from the rear plate 33. 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 connecting portion 3111 and the first obtuse angle α1 between the second front plate contact portion 3112 and the front plate connecting portion 3111 is 270°.

[0068] 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. 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. The first and second middle plate contact portions 321 and 322, as well as the second and second middle plate contact portions 322 and 323, respectively form a second obtuse angle α2, which is directed toward the receiving space 35. The third obtuse angle α3 is directed away from the partition 34. The third obtuse angle α3 is directed away from the receiving space 34. The third obtuse angle α3 is directed away from the receiving space 35.

[0069] The partition 34 is fixedly connected between the front panel connecting part 3111, the front panel marking part 312, the middle panel connecting part 322 and the rear panel 33.

[0070] The first front panel contact portion 3110, the first middle panel contact portion 321, part of the rear panel 33 and the partition member 34 form a first sub-accommodating space 351, and the second front panel contact portion 3112, the second middle panel contact portion 323, part of the rear panel 33 and the partition member 34 form a second sub-accommodating space 352. The first sub-accommodating space 351 and the second sub-accommodating space 352 are used to accommodate the ends of the first sub-edge banding strip 21, the second sub-edge banding strip 22, the third sub-edge banding strip 23 and the fourth sub-edge banding strip 24.

[0071] By using 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 distributed to multiple parts of the first sub-edge banding strip 21, the second sub-edge banding strip 22, the third sub-edge banding strip 23, and the fourth sub-edge banding strip 24, rather than concentrated on a single point. This effectively reduces local stress concentration and lowers the risk of damage to the door panel 1 caused by external impact. The design of the first obtuse angle α1, the second obtuse angle α2, and the third obtuse angle α3 makes the connection between the front panel transition portion 311, the middle panel 32, and the front panel transition portion 311 and the middle panel 32 more stable. Compared to right-angle or acute-angle structures, obtuse-angle structures can better disperse stress when subjected to force, reducing stress concentration caused by excessively small or large angles, thereby improving the stability of the front panel 31 and the middle panel 32. The setting of the first sub-accommodating space 351 and the second sub-accommodating space 352 makes reasonable use of the internal space of the buckle 3, hiding the two ends of the first sub-edge banding strip 21, the second sub-edge banding strip 22, the third sub-edge banding strip 23 and the fourth sub-edge banding strip 24 in the first sub-accommodating space 351 and the second sub-accommodating space 352, making the door panel cleaner and more beautiful in appearance.

[0072] The arc-shaped front panel marking 312 protrudes towards the rear panel 33, increasing the contact area between the front panel 31 and the middle panel 32 to a certain extent, thus further improving structural stability. Simultaneously, the arc-shaped structure itself also provides a certain degree of cushioning, enabling it to better adapt to different stress conditions.

[0073] The first front plate contact portion 3110, the front plate connecting portion 3111, and the second front plate contact portion 3112 are all trapezoidal, which makes the contact surface more stable. The lower bottom surfaces of the first front plate contact portion 3110 and the second front plate contact portion 3112 are tightly fitted with the first middle plate contact portion 321 and the second middle plate contact portion 323, respectively, and the upper bottom surface of the front plate connecting portion 3111 is tightly fitted with the middle plate connecting portion 322, which increases the contact area between the front plate 31 and the middle plate 32 and improves the reliability of the connection.

[0074] In one alternative embodiment, continue to refer to Figures 7-10As shown, the partition 34 includes a partition portion 341 and a partition connecting portion 342 connected to the partition portion 341. The partition connecting portion 342 divides the accommodating space 35 into a first sub-accommodating space 351 and a second sub-accommodating space 352. The partition connecting portion 342 is rod-shaped. The partition connecting portion 342 is inserted into each of the apex corners of the plate groove 12 on the side away from the partition portion 341.

[0075] Along the thickness direction of the door panel 1, the cross-sectional shape of the partition part 341 is a right trapezoid with a chamfer. The right trapezoid with a chamfer has an upper bottom edge, a lower bottom edge, a right angle side, and a hypotenuse. The upper bottom edge and the lower bottom edge are parallel to each other. The upper bottom edge, the right angle side, and the hypotenuse are connected to the middle panel connecting part 322, the rear panel 33, the front panel connecting part 3111, and the front panel marking part 312, respectively. The lower bottom edge and the partition connecting part 342 form an L-shaped structure.

[0076] Specifically, the partition 34 includes an integrally connected partition portion 341 and partition connecting portion 342. Along the thickness direction of the door panel 1, the cross-sectional shape of the partition portion 341 can be a right-angled trapezoid with a chamfer. The right-angled trapezoid with a chamfer has an upper base, a lower base, a right-angle side, and a hypotenuse. The upper base, right-angle side, and hypotenuse of the partition portion 341 are fixedly connected to the middle panel connecting portion 322, the rear panel 33, the front panel connecting portion 3111, and the front panel marking portion 312, respectively. For example, the upper base, right-angle side, and hypotenuse of the partition portion 341 are integrally connected to the middle panel connecting portion 322, the rear panel 33, the front panel connecting portion 3111, and the front panel marking portion 312. Specifically, the partition part 341 has its upper bottom edge integrally connected to the middle plate connecting part 322, its right-angled edge integrally connected to the rear plate 33, and its oblique edge integrally connected to the front plate connecting part 3111 and the front plate marking part 312. The partition part 341's upper bottom edge, right-angled edge, and oblique edge 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 marking part 312, respectively. 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 first sub-accommodating space 351 and the second sub-accommodating space 352 have the same volume.

[0077] The partition connecting part 342 is rod-shaped, and the partition connecting part 342 and the lower bottom edge of the partition part 341 form an L-shaped structure. The right angle of the L-shaped structure faces the front plate marking part 312. The partition connecting part 342 is inserted into each of the top corners of the plate groove 12 on the side away from the partition part 341. In this embodiment, the partition part 341 specifically 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, and the fifth side is the right angle 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 to each other. 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 connecting part 322, the second side is connected to the front plate connecting part 3111, the third side is connected to the front plate marking part 312, and the fifth side is connected to the rear plate 33 corresponding to the front plate marking part 312.

[0078] Using the above scheme, the bottom edge, right-angle edge, and oblique edge of the partition 341 are connected to the middle panel connecting part 322, the rear panel 33, the front panel connecting part 3111, and the front panel marking part 312, respectively. This multi-point connection method can effectively distribute the force, reduce local stress concentration, and improve the stability of the entire buckle 3. Among the four buckles 3, the partition connecting part 342 is rod-shaped and is inserted into each of the top corners of the panel groove 12, further enhancing the firmness of the connection between the buckle 3 and the door panel 1. The partition connecting part 342 divides the accommodating space 35 into a first sub-accommodating space 351 and a second sub-accommodating space 352. This equal division design makes the two sub-accommodating spaces 35 have the same volume, improving space utilization efficiency. The divided sub-accommodating spaces 35 can be used to accommodate the ends of the first sub-edge banding strip 21, the second sub-edge banding strip 22, the third sub-edge banding strip 23, and the fourth sub-edge banding strip 24, making the door panel neater.

[0079] The partition portion 341 has a chamfered right trapezoidal cross-section. The chamfer makes the edges smoother, reducing stress concentration caused by sharp edges and improving the durability of the buckle 3. The partition connection portion 342 is rod-shaped, which has high bending strength and can effectively withstand external impacts, improving the reliability of the connection.

[0080] The chamfered right-angled trapezoidal cross-section and L-shaped structure of the partition 341 make the entire partition 34 more harmonious and aesthetically pleasing. The partition connecting parts 342 of the four clips 3 interlock with the top corners of the panel grooves 12. This concealed design reduces exposed connecting parts, making the door panel surface smoother and cleaner, and improving the overall aesthetics of the door panel. The interlocking connection between the partition connecting parts 342 and the panel grooves 12 makes the assembly of the four clips 3, the first sub-edge banding strip 21, the second sub-edge banding strip 22, the third sub-edge banding strip 23, the fourth sub-edge banding strip 24, and the door panel 1 more convenient and faster, reducing assembly time and costs.

[0081] In one alternative embodiment, continue to refer to Figures 7-10 As shown, a first barb 343 is provided on the outer wall of the partition connecting part 342 on the side away from the partition part 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 towards the side away from the central axis of the partition connecting part 342 and is placed in the apex corner of the panel groove 12. The double inverted J-shaped cross-sectional shape is a hook-like structure. This double inverted J-shaped cross-sectional shape not only provides better grip and anti-loosening effect, but also better disperses stress when subjected to force, reducing structural damage caused by external impact. With this solution, the first barb 343 can be better embedded in the apex corner of the panel groove 12, providing stronger grip and preventing the partition connecting part 342 from loosening from the panel groove 12, thus improving the reliability of the connection. Protruding the first barb 343 toward the side away from the central axis of the partition connection 342 can increase the contact area between the first barb 343 and the groove 12 of the plate, thereby further improving the stability of the connection.

[0082] In one alternative embodiment, combined with Figure 2 , Figures 12-15 As shown, Figure 15 This is a cross-sectional view of a first sub-edge sealing strip, a second sub-edge sealing strip, a third sub-edge sealing strip, or a fourth sub-edge sealing strip provided by this utility model; in this embodiment, along the direction from the edge sealing body 210 to the insertion part 211, the insertion part 211 includes an insertion connecting section 2111, an insertion barb 2112, and an insertion ramp 2113 connected in sequence, and the side of the insertion connecting section 2111 away from the insertion barb 2112 is connected to the edge sealing body 210;

[0083] The cross-sectional shape of the plug-in connecting section 2111 along the thickness direction of the door panel 1 is rectangular. Along the thickness direction of the door panel 1, the two opposite sides of the plug-in barb 2112 are respectively provided with a second barb 21121 and a third barb 21122. The cross-sectional shape of the second barb 21121 and the third barb 21122 is lightning-shaped. Along the thickness direction of the door panel 1, the orthographic projection of the second barb 21121 overlaps with the orthographic projection of the third barb 21122. The second barb 21121 is located on the side of the third barb 21122 closer to the plug-in connecting section 2111.

[0084] The cross-sectional shape of the plug-in ramp portion 2113 along the thickness direction of the door panel 1 is an isosceles trapezoid. The isosceles trapezoid includes a parallel upper base side and a lower base side. Along the thickness direction of the door panel 1, the length of the upper base side is less than the length of the lower base side. The upper base side is located on the side of the lower base side away from the plug-in barb portion 2112.

[0085] Specifically, along the direction from the edge sealing body 210 to the insertion part 211, one end of the insertion barb 2112 is integrally connected to the insertion connecting section 2111, and the other end is integrally connected to the insertion ramp 2113. The end of the insertion connecting section 2111 away from the insertion barb 2112 is integrally connected to the edge sealing body 210. The insertion ramp 2113 is designed with a ramp 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 panel groove 12. The cross-sectional shape of the insertion connecting section 2111 along the thickness direction of the door panel 1 can be rectangular, and the long side of the insertion connecting section 2111 corresponds to the edge sealing body 210.

[0086] Along the thickness direction of the door panel 1, a second barb 21121 and a third barb 21122 are respectively provided on opposite sides of the insertion barb portion 2112. The cross-sectional shape of the second barb 21121 and the third barb 21122 is lightning-shaped (e.g., The lightning bolt shape extends along the edge sealing body 210 towards the insertion part 211; along the thickness direction of the door panel body 1, the orthographic projection of the second barb 21121 overlaps with the orthographic projection of the third barb 21122, the second barb 21121 is located on the side of the third barb 21122 near the insertion connection section 2111, and the third barb 21122 is located on the side of the second barb 21121 near the insertion slope part 2113; the cross-sectional shape of the insertion slope part 2113 along the thickness direction of the door panel body 1 is an isosceles trapezoid, the isosceles trapezoid includes a parallel upper base side and a lower base side of the slope, along the thickness direction of the door panel body 1, the length of the upper base side of the slope is less than the length of the lower base side of the slope, the lower base side of the slope is near the insertion barb part 2112, and the upper base side of the slope is away from the insertion barb part 2112.

[0087] The cross-sectional shapes of the second barb 21121 and the third barb 21122 are both "lightning bolt" shaped, which increases the friction between the insertion part 211 and the door panel 1, preventing the insertion part 211 from loosening or falling off during use. The orthographic projection of the second barb 21121 overlaps with the orthographic projection of the third barb 21122, enhancing the interaction between the second barb 21121 and the third barb 21122 and improving the overall stability. The cross-sectional shape of the insertion connection section 2111 along the thickness direction of the door panel 1 is rectangular. This rectangle has high bending and torsional strength and can effectively withstand various forces that may be generated during use. The cross-sectional shape of the insertion ramp 2113 is an isosceles trapezoid. This isosceles trapezoid can disperse stress and avoid stress concentration, thereby improving the overall strength of the first sub-edge banding strip 21, the second sub-edge banding strip 22, the third sub-edge banding strip 23, and the fourth sub-edge banding strip 24. The length of the upper bottom edge of the ramp 2113 is shorter than the length of the lower bottom edge, making the insertion of the 211 into the door panel 1 smoother, reducing resistance during installation, and improving ease of installation. The second barb 21121 is located near the third barb 21122 on the side close to the insertion section 2111. During insertion, the third barb 21122 contacts the door panel 1 first, providing initial positioning, and then the second barb 21121 further secures it, ensuring stable installation of the insertion part 211. The design of the second barb 21121, the third barb 21122, and the ramp allows for a tight fit between the insertion part 211 and the door panel 1, reducing gaps and improving sealing performance, preventing dust and moisture from entering the interior.

[0088] In one alternative embodiment, continue to refer to Figure 12 As shown, along the thickness direction of the door panel 1, the other side of the insertion barb 2112 corresponding to the third barb 21122 is the first plane, and the other side of the insertion barb 2112 corresponding to the second barb 21121 is the second plane; along the direction from the edge sealing body 210 to the insertion part 211, the side of the insertion connecting section 2111 that connects to the second plane is the third plane; along the thickness direction of the door panel 1, the distance a between the first plane and the third plane is greater than the distance b between the panel groove 12, and a fifth obtuse angle is formed between the second plane and the third barb 21122.

[0089] The second and third planes are on the same horizontal plane. The first and second planes are parallel to the third plane. The third barb 21122 forms a fifth obtuse angle with the second plane on the side near the insertion section 2111.

[0090] By setting the first, second, and third planes, the contact area and contact points between the insertion part 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, which is conducive to the interference fit between the insertion part 211 and the groove 12 of the panel, further enhancing the stability of the connection. The second plane and the third barb 21122 form a fifth obtuse angle, which can guide the insertion part 211 to smoothly insert into the groove 12 of the panel, reducing resistance and friction during installation and improving the accuracy and convenience of installation.

[0091] 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 synergy between the second barb 21121 and the third barb 21122 and the first, second, and third planes can not only further enhance the bending and torsional resistance of the structure and improve the load-bearing capacity of the interlocking part 211, but also enable the interlocking part 211 to fit tightly with the door panel 1, reducing gaps and thus improving sealing performance and preventing dust, moisture, etc. from entering the interior.

[0092] In one alternative embodiment, continue to refer to Figure 2 , Figures 12-15 As shown, along the direction from the sealing body 210 to the insertion part 211, the sealing body 210 includes a sealing glass contact part 2101, a sealing glue flow part 2102 and a sealing connection part 2103 connected in sequence, and the sealing connection part 2103 is connected to the insertion connection section 2111.

[0093] Along the thickness direction of the door panel 1, the cross-sectional shape of the edge-sealing glass contact portion 2101 is a right trapezoid. The edge-sealing adhesive flow portion 2102 includes a first adhesive flow section 21021 and a second adhesive flow section 21022, which are located on the side of the first adhesive flow section 21021 near the core board 4. The second adhesive flow section 21022 includes a first adhesive flow branch 21022a and a second adhesive flow branch 21022b connected to the first adhesive flow branch 21022a. The first adhesive flow branch 21022a is connected to the edge-sealing glass contact portion 2101, and the second adhesive flow branch 21022b is connected to the edge-sealing connection portion 2103. The angle between the first adhesive flow branch 21022a and the second adhesive flow branch 21022b is a sixth obtuse angle α6.

[0094] Specifically, along the direction from the sealing body 210 to the insertion part 211, one end of the sealing glue-flowing part 2102 is integrally connected to the sealing glass contact part 2101, and the other end is integrally connected to the sealing connection part 2103. The sealing connection part 2103 is integrally connected to the insertion connection section 2111.

[0095] Along the thickness direction of the door panel 1, the cross-sectional shape of the edge-sealing glass contact portion 2101 is a right trapezoid. The straight side of the right trapezoid is in direct contact with the glass chip. The edge-sealing adhesive flow portion 2102 includes a first adhesive flow section 21021 and a second adhesive flow section 21022, which are V-shaped structures. The included angle between the V-shaped structure of the first adhesive flow section 21021 and the V-shaped structure of the second adhesive flow section 21022 can be a sixth obtuse angle α6. The sixth obtuse angle α6 of the V-shaped structure in the first adhesive flow section 21021 and the V-shaped structure in the second adhesive flow section 21022 faces the glass core board side. Along the thickness direction of the door panel 1, the sixth obtuse angle α6 of the V-shaped structure in the first adhesive flow section 21021 and the sixth obtuse angle α6 of the V-shaped structure in the second adhesive flow section 21022 do not overlap at all.

[0096] The second adhesive section 21022 is located on the side of the first adhesive section 21021 near the core board 4. The second adhesive section 21022 includes an integrally connected first adhesive branch 21022a and second adhesive branch 21022b. The first adhesive branch 21022a is connected to the edge-sealing glass contact part 2101, and the second adhesive branch 21022b is connected to the edge-sealing connection part 2103. The angle between the first adhesive branch 21022a and the second adhesive branch 21022b is a sixth obtuse angle α6. Subsequently, adhesive is applied to the first adhesive branch 21022a and the second adhesive branch 21022b away from the first adhesive section 21021. The adhesive can be glass glue, structural adhesive, and nail-free adhesive.

[0097] The above solution not only ensures a stable connection between the edge-sealing body 210 and the plug-in connecting section 2111, but also provides a larger contact area, enhancing the adhesion stability with the glass and reducing the risk of loosening and detachment. Simultaneously, it guides the smooth flow of adhesive, reducing resistance and friction during installation and further improving sealing performance. Furthermore, by optimizing the structural design of the edge-sealing body 210, stress concentration points are reduced, improving the durability 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, thereby extending the product's service life.

[0098] In one alternative embodiment, continue to refer to Figure 2 , Figures 12-16 As shown, Figure 16This is a cross-sectional view of a portion of the edge sealing body of a first sub-edge sealing strip, a second sub-edge sealing strip, a third sub-edge sealing strip, or a fourth sub-edge sealing strip provided by this utility model; in this embodiment, the edge sealing connection part 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 connected in sequence. The first edge sealing connection segment 21130 is connected to a portion of the first adhesive flow segment 21021 and is located on the same horizontal plane. The sixth edge sealing connection segment 21135 is connected to the third plane of the insertion connection segment 2111 and is located on the same horizontal plane.

[0099] The first edge sealing connecting segment 21130 and the second edge sealing connecting segment 21131, the second edge sealing connecting segment 21131 and the third edge sealing connecting segment 21132, and the third edge sealing connecting segment 21132 and the fourth edge sealing connecting segment 21133 are perpendicular; the fourth edge sealing connecting segment 21133 and the fifth edge sealing connecting segment 21134, and the fifth edge sealing connecting segment 21134 and the sixth edge sealing connecting segment 21135 form a seventh obtuse angle α7.

[0100] Specifically, the edge sealing connection part 2103 includes an integrally connected first edge sealing connection segment 21130, second edge sealing connection segment 21131, third edge sealing connection segment 21132, fourth edge sealing connection segment 21133, fifth edge sealing connection segment 21134, and sixth edge sealing connection segment 21135. The first edge sealing connection segment 21130, second edge sealing connection segment 21131, third edge sealing connection segment 21132, fourth edge sealing connection segment 21133, and sixth edge sealing connection segment 21135 are straight segments, the fifth edge sealing connection segment 21134 is a diagonal segment, and the first edge sealing connection segment 21130... The first edge sealing connecting section 21130 is integrally connected to the side of the first adhesive section 21021 away from the edge sealing glass contact portion 2101, and the side of the first adhesive section 21021 away from the edge sealing glass contact portion 2101 is located on the same horizontal plane. The side of the sixth edge sealing connecting section 21135 away from the fifth edge sealing connecting section 21134 is integrally connected to the third plane of the plug-in connecting section 2111, and the third plane of the sixth edge sealing connecting section 21135 and the plug-in connecting section 2111 is located on the same horizontal plane, ensuring that the edge sealing connecting portion 2103 can be accurately aligned during installation and reducing installation errors.

[0101] A 90° angle is formed between the first edge sealing connecting segment 21130 and the second edge sealing connecting segment 21131, between the second edge sealing connecting segment 21131 and the third edge sealing connecting segment 21132, and between the third edge sealing connecting segment 21132 and the fourth edge sealing connecting segment 21133; a seventh obtuse angle α7 is formed between the fourth edge sealing connecting segment 21133 and the fifth edge sealing connecting segment 21134, and between the fifth edge sealing connecting segment 21134 and the sixth edge sealing connecting segment 21135.

[0102] By adopting the above scheme, the cross-sectional changes are smoothly transitioned through a multi-segment connection design, reducing abrupt changes in the cross-section. The first edge-sealing connection segment 21130 is perpendicular to the second edge-sealing connection segment 21131, the second edge-sealing connection segment 21131 is perpendicular to the third edge-sealing connection segment 21132, and the third edge-sealing connection segment 21132 is perpendicular to the fourth edge-sealing connection segment 21133. This also allows for gradual changes in the cross-sectional shape, avoiding abrupt changes. The fourth edge-sealing connection segment 21133 is perpendicular to the fifth edge-sealing connection segment 21134, and the fifth edge-sealing connection segment 21134 is perpendicular to the sixth edge-sealing connection segment 21135, forming a seventh obtuse angle α7. This seventh obtuse angle α7 design allows for a smooth transition of stress, reducing stress concentration, thereby improving the durability of the structure and extending the product's service life.

[0103] Optionally, continue to refer to Figure 2 , Figures 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 to 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.

[0104] If the width of the middle plate 32 along the arc length of the rear plate 33 is too large, gaps will exist between the first sub-edge banding strip 21, the second sub-edge banding strip 22, the third sub-edge banding strip 23, and the fourth sub-edge banding strip 24 and their corresponding clips 3. If the width of the middle plate 32 along the arc length of the rear plate 33 is too small, the fit between the first sub-edge banding strip 21, the second sub-edge banding strip 22, the third sub-edge banding strip 23, and the fourth sub-edge banding strip 24 and their corresponding clips 3 will be too tight, making installation inconvenient. Therefore, continue to refer to... Figure 2 , Figures 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 7.9mm to 8.1mm. This not only minimizes gaps between the first sub-edge banding strip 21, the second sub-edge banding strip 22, the third sub-edge banding strip 23, and the fourth sub-edge banding strip 24 and their corresponding buckles 3, but also prevents excessive tightness between the first sub-edge banding strip 21, the second sub-edge banding strip 22, the third sub-edge banding strip 23, and the fourth sub-edge banding strip 24 and their corresponding buckles 3. The width of the intermediate plate 32 along the arc length direction of the rear plate 33 can be 7.9mm, 8.0mm, or 8.1mm.

[0105] As can be seen from the above embodiments, the door panel with anti-detachment buckle structure provided by this utility model achieves at least the following beneficial effects:

[0106] First, the sealing strip surface requires no nail holes: Adopting a completely new fixing method, it eliminates the traditional nailing process, resulting in a smooth and flat surface without any nail hole marks. This greatly enhances the overall aesthetics of the door panel and avoids problems such as paint peeling and exposure of internal structures at nail holes, thus increasing product durability. Second, by connecting the first, second, third, and fourth sub-edge banding strips with corner brackets, each strip is inserted into the first and second receiving spaces of different corner brackets. This eliminates the need for a tight 45° angled fit between the strips, improving the door panel's appearance and effectively preventing dust and dirt accumulation at the corners, facilitating cleaning and maintenance, and extending the door panel's lifespan. Third, the sealing strip assembly is convenient and efficient: The improved assembly process significantly reduces the skill requirements for operators. The assembly process is simple and easy, requiring no complex operating skills or tools. Operators can quickly and accurately complete the assembly of the sealing strips, significantly improving production efficiency, reducing labor intensity, and also reducing quality problems caused by improper operation, thus improving the overall quality of the product. Fourth, because the splicing method between the first, second, third, and fourth sub-edge sealing strips and the corner code has been changed, there is no need to manually chisel right angles at the inside corners of the sealing strips, saving a lot of time and labor costs.

[0107] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can 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.
