Description

Technical Field

[0001] The utility model relates to the technical field of furniture production, and more specifically, to an anti-deformation assembled door panel. Background Art

[0002] With the progress of social civilization, people's living standards are constantly improving, the pursuit of quality of life is constantly improving, and the aesthetic value is constantly improving. More and more families choose to buy wooden furniture, such as cabinets, wardrobes, coffee tables, shoe cabinets, etc. Most of the doors used in existing furniture are board-frame composite structures. Solid wood kitchen cabinet doors are usually made of solid wood panels. Common solid wood cabinets are mainly pure solid wood and composite solid wood. Solid wood integrated cabinets are natural environmentally friendly products with high prices. In addition, there are unavoidable factors such as shrinkage and swelling of the wood itself in the solid wood core board. The moisture content of solid wood makes the humidity of the kitchen cabinet relatively unstable. In the rainy season in winter, deformation problems will occur. In hot weather, if it is exposed to direct sunlight, or the continuation of dry weather, the solid wood integrated cabinet will crack.

[0003] In order to pursue aesthetic effects, the framed door panels generally adopt narrow frame types, and the existing narrow framed door panels, such as Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of the planar structure of a narrow frame door panel in the existing design. Figure 2 yes Figure 1 The cross-sectional structure diagram at J1 is as follows: Figure 1 and Figure 2 The existing narrow frame type assembled door panel shown is a simple straight line frame 10' without shape and slope and a door panel 20' directly combined. Since the frame 10' and the door panel 20' are directly flatly pasted and have no mutual bite force, the door panel is prone to cracking, deformation and other quality problems after a long time, which greatly shortens the service life of the door panel and affects normal use.

[0004] In the existing frame door panel design, some structures are also designed to prevent cracking. For example, the application document with Chinese patent application number 201821128321.X and application date July 17, 2018 discloses a new type of wooden door leaf, including a door frame and a door panel, the door frame includes a horizontal frame and a vertical frame, the cross-sections of the vertical frame and the horizontal frame are both U-shaped structures, the left and right sides of the door panel are inserted into the U-shaped groove of the vertical frame, the inner surface of the open end of the vertical frame is provided with a card slot 1, and the left and right sides of the door panel are respectively provided with a card block adapted to the card slot 1; the upper and lower ends of the door panel are inserted into the U-shaped groove of the horizontal frame, and the inner surface of the open ends of the two ends of the horizontal frame is provided with a card slot 2 adapted to the card block; a gap is provided between the door panel and the horizontal frame and the vertical frame, and the gap is filled with a glue layer, and the door panel is fixedly connected to the horizontal frame and the vertical frame through the glue layer, which can solve the problem of door leaf deformation and paint cracking caused by thermal expansion and contraction of the wooden door leaf. The edge of the wooden door leaf structure is wrapped by a fully enclosed U-shaped frame to wrap the edge of the door panel. Although it can play a certain role in preventing cracking, it is complex in structure and cumbersome in installation, and cannot achieve the effect of an aesthetically pleasing assembled door panel with a narrow frame.

[0005] For example, the application document with Chinese patent application number 202121121165.6 and application date May 24, 2021 discloses a door panel structure for preventing paint cracking, including a frame and a vertical frame; the frame and the vertical frame form a core panel installation area; a door core panel is arranged in the core panel installation area, and a first slot is arranged on the side of the frame and the vertical frame near the core panel installation area; the frame and the vertical frame are assembled by mortise and tenon joints; a second slot is arranged on the backlight side of the frame and the vertical frame; a back card strip is arranged in the second slot; the back card strip is against the door panel core; a right-angle edge banding is arranged at the connection between the frame and the vertical frame, and the frame and the vertical frame are connected by a right-angle edge banding through the first mortise and tenon grooves and the second mortise and tenon grooves at the ends of the frame and the vertical frame, instead of being directly connected, thereby greatly reducing the extrusion and deformation of the frame and the vertical frame due to deformation; at the same time, the core panel is abutted against the area composed of the frame and the vertical frame through the back pressure strip, which is easy to replace and can effectively solve the paint cracking problem of the 45-degree combination of traditional solid wood door frames. Although the edge of the door panel structure is wrapped by a semi-wrapped L-shaped frame, the structure is relatively simple and can play a certain role in preventing cracking, but the structure is cumbersome to install and still cannot achieve the effect of an aesthetically pleasing assembled door panel with a narrow frame.

[0006] Therefore, there is an urgent need to provide an assembled door panel with a simple structure, quick and easy installation, and the ability to achieve a beautiful narrow-frame assembled door panel effect, while also improving quality problems such as cracking and deformation of the door panel, thereby increasing the service life of the product and preventing deformation.

[0027] Compared with the prior art, the anti-deformation assembled door panel provided by the utility model achieves at least the following beneficial effects:

[0028] The anti-deformation assembled door panel provided by the utility model realizes the aesthetic effect of the narrow frame of the assembled door panel by opening a special milling groove and a middle groove structure on the core plate, and cooperating with a narrow width horizontal support structure, a longitudinal support structure, and a middle support structure. The chamfered surface of the milling groove is also provided to form an engaging surface with the horizontal support structure and the longitudinal support structure, and the included angle between the longitudinal section of the milling groove and the chamfered surface is an acute angle. After the horizontal support clipping part is filled in the milling groove, and the longitudinal support clipping part is filled in the milling groove, the engaging force of the horizontal support clipping part, the longitudinal support clipping part and the milling groove can be enhanced, and the friction force after the two clipping can be increased. The horizontal support covering part covers part of the assembly surface of the core plate, and the longitudinal support covering part covers part of the assembly surface of the core plate, so that the frame formed by the horizontal support structure and the longitudinal support structure can better cover the milling groove at the edge of the core plate. The cross section of the middle groove in the middle of the core board is also set to be trapezoidal. After the middle support embedding part is embedded in the middle groove with a trapezoidal cross section, the bite force and friction force can be greatly enhanced, and the middle support covering parts on both sides of the middle support structure respectively wrap the part of the assembly surface of the core board outside the middle groove, so that the middle support structure can better wrap the core board, effectively avoiding the quality problems of cracking and deformation of the door board in the middle position, improving the service life and product quality of the assembled door board with a narrow frame, and at the same time, the middle support structure can be set in the middle of the core board to play a better abutment and stabilization role for the longer longitudinal support structure. The end of the horizontal support embedding part away from the horizontal support covering part is flush with the edge of the short side of the core board, and the end of the longitudinal support embedding part away from the longitudinal support covering part is flush with the edge of the long side of the core board, which is conducive to ensuring the aesthetics of the overall door board, and can avoid the presence of a cracking point at the edge of the door board when the two are not flush or there is a protruding part. By setting the transverse sealing layer and the longitudinal sealing layer, external influencing factors such as water and oxygen can be prevented from entering the clamping gap between the core plate and the transverse brace clamping part and the longitudinal brace clamping part, which is beneficial to improve the assembly stability of the transverse brace structure, the longitudinal brace structure and the core plate. The triangular notch opened on the side of the longitudinal brace structure facing the central brace structure can increase the contact area of ​​the longitudinal brace structure and the central brace structure during assembly, improve the abutment stability of the central brace structure against the longer longitudinal brace structure, and further prevent the entire assembled door panel from deforming. The anti-deformation assembled door panel structure of the utility model is simple in structure and easy and quick to assemble. During assembly, it is only necessary to assemble and fix the milled core plate, the longitudinal brace structure, the transverse brace structure and the central brace structure, and then paint the product. While achieving the effect of an assembled door panel with a beautiful narrow frame, it can also improve the quality problems such as cracking and deformation of the door panel, which is beneficial to improving the service life and product quality of the product.

[0029] Of course, any product implementing the present utility model does not necessarily need to achieve all of the above-mentioned technical effects at the same time.

[0067] Specifically, the anti-deformation assembled door panel provided in this embodiment can be applied to narrow-frame door panels with aesthetic requirements, and the special milling groove structure and assembly structure can improve the quality problems of door panel cracking, deformation, etc. Figure 3 and Figure 4 As shown, the anti-deformation assembled door panel 000 includes a core panel 10, one side of the core panel 10 includes an assembly surface 10A, and the assembly surface 10A can be understood as a surface for subsequent milling grooves and mounting frames. Figure 7 and Figure 8 As shown, Figure 8 yes Figure 7An enlarged structural schematic diagram at J2 in the figure, the edge of the core plate 10 includes a milling groove 10K, the opening of the milling groove 10K faces one side of the assembly surface 10A, and the milling groove 10K can be formed by digging a depression at the edge of the assembly surface 10A of the core plate 10. The special milling groove 10K structure set at the edge of the core plate 10 in this embodiment includes a longitudinal section 10K1 and an oblique section 10K2, the angle α between the longitudinal section 10K1 and the oblique section 10K2 is an acute angle, the plane where the longitudinal section 10K1 is located is parallel to the assembly surface 10A, and the plane where the oblique section 10K2 is located intersects with the assembly surface 10A, that is, the milling groove 10K forms a fitting surface with the frame when the frame is subsequently assembled through the longitudinal section 10K1, and forms a bite surface with the frame when the frame is subsequently assembled through the oblique section 10K2. This embodiment is described by taking the rectangular shape of the core board 10 as an example. The core board 10 includes a long side 10C and a short side 10D. The milling groove 10K at the position of the long side 10C is embedded with a longitudinal bracing structure 20, and the milling groove 10K at the position of the short side 10D is embedded with a transverse bracing structure 30, that is, the entire door panel structure can include two oppositely arranged transverse bracing structures 30 and two oppositely arranged longitudinal bracing structures 20, and the transverse bracing structures 30 and the longitudinal bracing structures 20 surround the edge of the core board 10 to form a frame structure of the door panel.

For example, if the width of the short side 10D of the core board 10 is 400-500mm, the transverse bracing structure 30 and the longitudinal bracing structure 20 with a width of 20-30mm can be selected, thereby ensuring that the frame structure formed by the transverse bracing structure 30 and the longitudinal bracing structure 20 around the edge of the core board 10 is a narrow frame of the core board 10, so as to achieve the aesthetic effect of the narrow frame of the assembled door panel.

[0068] like Figure 7 and Fig. 9 As shown, Fig. 9 yes Figure 7 The enlarged structural diagram at J3 is a direction Y pointing from one short side 10D of the core plate 10 to the other short side 10D of the core plate 10.

The middle support structure 40 is used to stabilize the long longitudinal support structure 20 at the middle position of the core plate 10. In addition, the width of the middle support structure 40 can be set to be narrow, for example, consistent with the width of the horizontal support structure 30, so as to reduce the impact of the middle support structure 40 on the overall aesthetics after being assembled on the assembly surface 10A of the core plate 10.

[0069] The anti-deformation assembled door panel 000 provided in this embodiment is designed with special shapes and structures of the horizontal support structure 30, the longitudinal support structure 20 and the middle support structure 40 in order to achieve the effect of an assembled door panel with a beautiful narrow frame and solve the quality problems such as cracking and deformation of the door panel. Specifically:

[0070] like Figure 5 , Figure 7 , Figure 8 and Figure 10-11 As shown, Fig.10 yes Figure 5 The planar structural diagram of the cross brace structure in FIG. Fig.11 yes Fig.10 The cross-bracing structure of the cross-bracing structure in the C-C' direction is a schematic diagram of the cross-bracing structure in the embodiment.

After the cross-bracing embedding portion 301 is filled in the milling groove 10K, the bite force between the cross-bracing embedding portion 301 and the milling groove 10K can be enhanced, and the friction force after the two are embedded can also be increased. The cross-bracing covering portion 302 of the cross-bracing structure 30 is located outside the milling groove 10K, and the cross-bracing covering portion 302 is fitted and fixed to the partial assembly surface 10A outside the milling groove 10K, which is equivalent to the cross-bracing covering portion 302 covering the partial assembly surface 10A of the core board 10, so that the cross-bracing structure 30 can better cover the milling groove 10K at the edge of the short side 10D of the core board 10.

[0071] like Figure 5 and Figure 12-13 As shown, Fig.12 yes Figure 5 The plane structure diagram of the longitudinal bracing structure in FIG. Fig.13 yes Fig.12The longitudinal bracing structure 20 of the embodiment is a schematic cross-sectional structure diagram of the longitudinal bracing structure along the D-D' direction. The longitudinal bracing structure 20 of the embodiment includes a longitudinal bracing card embedding portion 201 and a longitudinal bracing covering portion 202 of an integral structure. The longitudinal bracing card embedding portion 201 is filled in the milling groove 10K, and the longitudinal bracing covering portion 202 is located outside the milling groove 10K. The longitudinal bracing covering portion 202 is fitted and fixed to a partial assembly surface 10A outside the milling groove 10K. The longitudinal section 10K1 of the milling groove 10K forms a fitting surface with the longitudinal bracing structure 20. The oblique section 10K2 of the milling groove 10K forms a bite surface with the longitudinal bracing structure 20. The longitudinal section 10K1 The angle α with the beveled surface 10K2 is an acute angle. After the longitudinal support embedding portion 201 is filled in the milling groove 10K, the bite force between the longitudinal support embedding portion 201 and the milling groove 10K can be enhanced, and the friction force after the two are embedded can also be increased. The longitudinal support covering portion 202 of the longitudinal support structure 20 is located outside the milling groove 10K, and the longitudinal support covering portion 202 is fitted and fixed to the partial assembly surface 10A outside the milling groove 10K, which is equivalent to the longitudinal support covering portion 202 covering the partial assembly surface 10A of the core board 10, so that the longitudinal support structure 20 can better cover the milling groove 10K at the edge of the long side 10C of the core board 10.

[0072] The anti-deformation assembled door panel 000 of this embodiment, through the transverse bracing structure 30 and the longitudinal bracing structure 20 of the above-mentioned structure, forms a frame structure around the edge of the core panel 10 to wrap around the core panel 10, which can effectively avoid the quality problems of cracking and deformation of the door panel edges, and is beneficial to improving the service life and product quality of the assembled door panel with narrow frames.

[0073] like Figure 5 , Figure 7 , Fig. 9 and Figure 14-15 As shown, Fig.14 yes Figure 5 The plane structure diagram of the central support structure in the figure is as follows: Fig.15 yes Fig.14The schematic diagram of the cross-sectional structure of the central support structure in the E-E' direction, the central support structure 40 of this embodiment includes a central support embedded part 401 and two central support covering parts 402 of an integral structure, along a short side 10D of the core plate 10 pointing to the direction Y of the other short side 10D of the core plate 10, the two central support covering parts 402 are respectively located on both sides of the central support embedded part 402, the central support embedded part 401 is filled in the middle groove 10M, the central support covering part 402 is located outside the middle groove 10M, and the central support covering part 402 is fitted and fixed to the partial assembly surface 10A outside the middle groove 10M, by opening a middle groove 10M with a trapezoidal cross section in the middle position of the core plate 10, the bottom surface and two side surfaces of the middle groove 10M with a trapezoidal cross section form a fitting surface with the central support structure 40, and the middle groove 10M with a trapezoidal cross section, due to the groove of the middle groove 10M The bottom is wider and the groove of the middle groove 10M is narrower, which can greatly enhance the bite force between the middle support embedding part 401 and the middle groove 10M and increase the friction after the two are embedded. The middle support covering part 402 of the middle support structure 40 is located outside the middle groove 10M, and the middle support covering part 402 is fitted and fixed to the partial assembly surface 10A outside the middle groove 10M, which is equivalent to the middle support covering parts 402 on both sides of the middle support structure 40 respectively covering the partial assembly surface 10A of the core board 10 outside the middle groove 10M, so that the middle support structure 40 can better wrap the core board 10, effectively avoiding the quality problem of cracking and deformation of the door panel in the middle position, improving the service life and product quality of the assembled door panel with a narrow frame, and at the same time, the middle support structure 40 can be set in the middle position of the core board 10 to play a better abutment and stabilization role for the longer longitudinal support structure 20.

[0074] Please refer to Figure 3-Figure 8 and Fig.16 , Fig.17 , Fig.16 yes Figure 5 Another cross-sectional structure schematic diagram along the A-A' direction, Fig.17 yes Figure 7 Another enlarged structural schematic diagram at J2 in the middle, in this embodiment, the end of the horizontal brace embedding portion 301 away from the horizontal brace covering portion 302 is flush with the edge of the short side 10D of the core plate 10, and the end of the longitudinal brace embedding portion 201 away from the longitudinal brace covering portion 202 is flush with the edge of the long side 10C of the core plate 10.

[0075] In the present embodiment, a milling groove 10K is provided at the edge of the core panel 10. After the frame formed by the transverse bracing structure 30 and the longitudinal bracing structure 20 is embedded in the milling groove 10K, the end of the transverse bracing embedding portion 301 away from the transverse bracing covering portion 302 is flush with the edge of the short side 10D of the core panel 10, and the end of the longitudinal bracing embedding portion 201 away from the longitudinal bracing covering portion 202 is flush with the edge of the long side 10C of the core panel 10, which is beneficial to ensure the aesthetics of the overall door panel and avoid the presence of cracking points at the edge of the door panel when the two are not flush or there are protruding parts.

[0076] like Fig.17 As shown, in this embodiment, a transverse sealing layer 50 may be provided between one end of the transverse brace embedding portion 301 away from the transverse brace covering portion 302 and the edge of the short side 10D of the core plate 10, such as Fig.16 As shown, the longitudinal support embedding portion 201 includes a longitudinal sealing layer 60 on one end away from the longitudinal support covering portion 202 and on the edge of the long side 10C of the core plate 10 . This embodiment explains that a transverse sealing layer 50 can be coated on the edge of one end of the transverse brace embedding portion 301 away from the transverse brace covering portion 302 and the short side 10D of the core panel 10, and a longitudinal sealing layer 60 can be coated on the edge of one end of the longitudinal brace embedding portion 201 away from the longitudinal brace covering portion 202 and the long side 10C of the core panel 10. The materials of the transverse sealing layer 50 and the longitudinal sealing layer 60 can be the same, and can both be made of sealant. The transverse sealing layer 50 at least covers the gap between the core panel 10 and the transverse brace embedding portion 301, and the longitudinal sealing layer 60 at least covers the gap between the core panel 10 and the longitudinal brace embedding portion 201. By setting the transverse sealing layer 50 and the longitudinal sealing layer 60, external influencing factors such as water and oxygen can be prevented from entering the engaging gap between the core panel 10 and the transverse brace embedding portion 301 and the longitudinal brace embedding portion 201, which is beneficial to improve the assembly stability of the transverse brace structure 30, the longitudinal brace structure 20 and the core panel 10.

[0077] like Figure 5 and Fig.12 As shown, the longitudinal support structure 20 in this embodiment is provided with a triangular slot 20K on one side facing the middle support structure 40, and both ends of the middle support structure 40 are fixed to the longitudinal support structure 20 by being embedded in the triangular slot 20K. The opening of the triangular slot 20K can increase the contact area between the longitudinal support structure 20 and the middle support structure 40 when they are assembled, which is beneficial to improve the abutment stability of the middle support structure 40 against the longer longitudinal support structure 20, and can further prevent the entire assembled door panel from deformation.

[0078] The anti-deformation assembled door panel 000 provided in this embodiment realizes the aesthetic effect of the narrow frame of the assembled door panel by opening a special milling groove 10K and a middle groove 10M structure on the core panel 10, in combination with a narrow width transverse support structure 30, a longitudinal support structure 20, and a middle support structure 40. A chamfered surface 10K2 of the milling groove 10K is also provided to form an engaging surface with the transverse brace structure 30 and the longitudinal brace structure 20. The included angle α between the longitudinal section 10K1 of the milling groove 10K and the chamfered surface 10K2 is an acute angle. After the transverse brace embedding portion 301 is filled in the milling groove 10K and the longitudinal brace embedding portion 201 is filled in the milling groove 10K, the engaging force between the transverse brace embedding portion 301 and the longitudinal brace embedding portion 201 and the milling groove 10K can be enhanced, and the friction force after the two are embedded can also be increased. The transverse brace covering portion 302 covers a partial assembly surface 10A of the core board 10, and the longitudinal brace covering portion 202 covers a partial assembly surface 10A of the core board 10, so that the frame formed by the transverse brace structure 30 and the longitudinal brace structure 20 can better cover the milling groove 10K at the edge of the core board 10. The cross-section of the middle groove 10M in the middle position of the core panel 10 is also set to be trapezoidal. After the middle support embedding part 401 is embedded in the middle groove 10M with a trapezoidal cross-section, the bite force and friction force can be greatly enhanced, and the middle support covering parts 402 on both sides of the middle support structure 40 respectively wrap the partial assembly surface 10A of the core panel 10 outside the middle groove 10M, so that the middle support structure 40 can better wrap the core panel 10, effectively avoiding the quality problem of cracking and deformation of the door panel in the middle position, improving the service life and product quality of the assembled door panel with a narrow frame, and at the same time, the middle support structure 40 can be set in the middle position of the core panel 10 to play a better abutment and stabilization role for the longer longitudinal support structure 20. One end of the transverse brace embedding portion 301 away from the transverse brace covering portion 302 is flush with the edge of the short side 10D of the core panel 10, and one end of the longitudinal brace embedding portion 201 away from the longitudinal brace covering portion 202 is flush with the edge of the long side 10C of the core panel 10, which is beneficial to ensure the aesthetics of the overall door panel and can avoid the presence of cracking points on the edge of the door panel when the two are not flush or there are protruding parts. By setting the transverse sealing layer 50 and the longitudinal sealing layer 60, external influencing factors such as water and oxygen can be prevented from entering the engaging gap between the core panel 10 and the transverse support embedding part 301 and the longitudinal support embedding part 201, which is beneficial to improve the assembly stability of the transverse support structure 30, the longitudinal support structure 20 and the core panel 10. The triangular notch 20K opened on the side of the longitudinal support structure 20 facing the middle support structure 40 can increase the contact area between the longitudinal support structure 20 and the middle support structure 40 during assembly, improve the abutment stability of the middle support structure 40 against the longer longitudinal support structure 20, and further prevent the entire assembled door panel from deformation.The anti-deformation assembled door panel 000 of this embodiment has a simple structure and is quick and easy to assemble. During assembly, it is only necessary to assemble and fix the milled core panel (the core panel after the milling groove 10K and the middle groove 10M are opened), the longitudinal support structure 20, the transverse support structure 30, and the middle support structure 40, and then paint the completed product. While achieving the effect of an assembled door panel with a beautiful narrow frame, it can also improve quality problems such as cracking and deformation of the door panel, which is beneficial to improving product service life and product quality.

[0079] Embodiment 2

[0080] In some optional embodiments, such as Figure 5 , Fig.10 and Fig.12 As shown, the connection between the horizontal brace structure 30 and the longitudinal brace structure 20 in this embodiment is the horizontal brace oblique side 30X, and the connection between the longitudinal brace structure 20 and the horizontal brace structure 30 is the longitudinal brace oblique side 20X. The horizontal brace oblique side 30X and the longitudinal brace oblique side 20X are mutually fitted and fixed. By fitting the horizontal brace oblique side 30X at the connection between the horizontal brace structure 30 and the longitudinal brace structure 20 and the longitudinal brace oblique side 20X at the connection between the longitudinal brace structure 20 and the horizontal brace structure 30, the contact area between the longitudinal brace structure 20 and the horizontal brace structure 30 can be increased, and the stability of the entire frame can be improved. It can be understood that the connection between the horizontal brace structure 30 and the longitudinal brace structure 20 in this embodiment can be fixedly connected by gluing, screws or other methods, and this embodiment is not limited here.

[0081] Optionally, when the transverse bracing structure 30 in this embodiment is assembled with the milling groove 10K of the core board 10, the transverse bracing structure 30 can be fixed by embedding the milling groove 10K through the glue layer; when the longitudinal bracing structure 20 is assembled with the milling groove 10K of the core board 10, the longitudinal bracing structure 20 can be fixed by embedding the milling groove 10K through the glue layer; when the middle bracing structure 40 is assembled with the middle groove 10M of the core board 10, the middle bracing structure 40 can also be fixed by embedding the middle groove 10M through the glue layer. By applying the glue layer (not shown in the figure) in the milling groove 10K and the middle groove 10M, or by applying the glue layer on the assembly surfaces of the longitudinal bracing structure 20, the transverse bracing structure 30 and the middle bracing structure 40, the overall stability of the longitudinal bracing structure 20, the transverse bracing structure 30 and the middle bracing structure 40 after being assembled with the core board 10 can be further enhanced.

[0082] Embodiment 3

[0083] In some optional embodiments, please refer to Figure 3-Figure 8In this embodiment, the milling groove 10K opened on the edge of the core board 10 includes a longitudinal section 10K1 and a chamfered section 10K2. The angle α between the longitudinal section 10K1 and the chamfered section 10K2 is an acute angle. The plane where the longitudinal section 10K1 is located is parallel to the assembly surface 10A, and the plane where the chamfered section 10K2 is located intersects with the assembly surface 10A. The angle between the longitudinal section 10K1 and the chamfered section 10K2 is α, 70°≤α≤75°.

[0084] This embodiment explains that in order to increase the bite force and friction force between the transverse brace embedment 301 and the longitudinal brace embedment 201 and the milling groove 10K after the transverse brace embedment 301 is filled in the milling groove 10K and the longitudinal brace embedment 201 is filled in the milling groove 10K, the angle α between the longitudinal section 10K1 and the oblique section 10K2 can be set to an acute angle, optionally, 70°≤α≤75°, preferably, 72°≤α≤73°, so that the angle α formed by the longitudinal section 10K1 and the oblique section 10K2 is within a range, which can avoid the problem that the angle α is too small to cause the transverse brace embedment 301 and the longitudinal brace embedment 201 to be not easy to install with the milling groove 10K, and the angle α is too large to cause the bite force between the transverse brace embedment 301 and the longitudinal brace embedment 201 and the milling groove 10K to be insufficient, thereby affecting the firmness of the assembly. Therefore, in this embodiment, the angle α between the longitudinal section 10K1 and the oblique section 10K2 of the milling groove 10K is set to be an acute angle, and 70°≤α≤75°, which can ensure that the horizontal support embedding portion 301 and the longitudinal support embedding portion 201 have sufficient bite force and friction force after being embedded in the milling groove 10K, which is beneficial to improve the overall stability of the door panel after assembly.

[0085] Optional, such as Figure 3-Figure 8 As shown, in this embodiment, along the direction Z perpendicular to the plane where the core board 10 is located, the depth of the milling groove 10K opened at the edge of the core board 10 is D1, the thickness of the core board 10 is D0, 1 / 3D0≤D1≤2 / 3D0, that is, the depth D1 of the milling groove 10K opened at the edge of the core board 10 is less than or equal to two-thirds of the thickness D0 of the core board 10, but the depth D1 of the milling groove 10K needs to be greater than or equal to one-third of the thickness D0 of the core board 10, thereby avoiding the depth D1 of the milling groove 10K being too deep, affecting the stability of the edge of the core board 10 after the transverse bracing structure 30 and the longitudinal bracing structure 20 are assembled at the edge of the core board 10, and also avoiding the depth D1 of the milling groove 10K being too shallow, resulting in insufficient bite force after the transverse bracing embedding portion 301 and the longitudinal bracing embedding portion 201 are embedded with the milling groove 10K. Therefore, in this embodiment, the depth D1 of the milling groove 10K is set to be less than or equal to two-thirds of the thickness D0 of the core board 10, but the depth D1 of the milling groove 10K needs to be greater than or equal to one-third of the thickness D0 of the core board 10, which is beneficial to ensure the stability of the overall assembly while ensuring that the horizontal support embedding part 301 and the vertical support embedding part 201 have sufficient bite force and friction force after being embedded in the milling groove 10K.

[0086] Optional, such as Figure 3-Figure 9 As shown, in this embodiment, along the direction Y from one short side 10D of the core plate 10 to the other short side 10D of the core plate 10, the width W1 of the cross brace covering portion 302 is in the range of 2.5-7 mm, and the width W2 of a middle brace covering portion 402 is in the range of 2.5-7 mm;

[0087] Along the direction from one long side 10C of the core plate 10 to the other long side 10C of the core plate 10 , the width W3 of the longitudinal support covering portion 202 is in the range of 2.5-7 mm.

[0088] This embodiment explains that the cross brace covering portion 302 of the cross brace structure 30 is located outside the milling groove 10K, and the cross brace covering portion 302 is fixed to the partial assembly surface 10A outside the milling groove 10K, which is equivalent to the cross brace covering portion 302 covering the partial assembly surface 10A of the core board 10, so that the cross brace structure 30 can better cover the milling groove 10K at the edge of the short side 10D of the core board 10. Similarly, the longitudinal support covering portion 202 covers the partial assembly surface 10A of the core board 10, and the middle support covering portion 402 of the middle support structure 40 better covers the core board 10. In order to achieve better anti-deformation and anti-cracking effects, the width W1 of the cross brace covering portion 302, the width W2 of the middle support covering portion 402, and the width W3 of the longitudinal support covering portion 202 can be set to be 2.5-7mm, thereby avoiding the width of the covering portion being too wide to affect the aesthetic effect of the narrow frame of the frame, and avoiding the width of the covering portion being too narrow to affect the wrapping effect on the core board 10. Therefore, the width range of the covering part set in this embodiment can not only achieve the aesthetic effect of a narrow frame, but also improve the covering and wrapping effect of the covering part on the core board 10, thereby enhancing the anti-deformation and anti-cracking effects.

[0089] Optionally, the core board 10 in this embodiment includes a density board, and the middle support structure 40, the cross support structure 30, and the longitudinal support structure 20 include solid wood boards. The core board 10 in this embodiment can be made of density board, which is also called fiberboard. It is a man-made board made of wood fiber or other plant fiber as raw materials and urea-formaldehyde resin or other applicable adhesives. According to their density, it is divided into high-density board, medium-density board, and low-density board. Density board is a good material for making furniture because it is soft and impact-resistant and easy to reprocess. Compared with the price, density board is relatively cheap. Therefore, the large area of ​​the core board 10 in the door panel is made of density board, which can save costs and reduce the difficulty of processing. The middle support structure 40, the cross support structure 30, and the longitudinal support structure 20 in this embodiment can be made of solid wood boards. The solid wood boards are sturdy and durable, with natural grains. After being assembled with the core board 10, they can play a good role in preventing deformation and cracking.

[0090] Optionally, the exposed surfaces of the central support structure 40, the transverse support structure 30, and the longitudinal support structure 20 in the present embodiment are all curved structures. By designing the exposed surfaces of the central support structure 40, the transverse support structure 30, and the longitudinal support structure 20, that is, the surfaces exposed and visible to the outside, as curved surfaces, the aesthetics of the overall door panel can be increased through the shape design of the exposed surfaces.

[0091] It can be seen from the above embodiments that the anti-deformation assembled door panel provided by the utility model achieves at least the following beneficial effects:

[0092] The anti-deformation assembled door panel provided by the utility model realizes the aesthetic effect of the narrow frame of the assembled door panel by opening a special milling groove and a middle groove structure on the core plate, and cooperating with a narrow width horizontal support structure, a longitudinal support structure, and a middle support structure. The chamfered surface of the milling groove is also provided to form an engaging surface with the horizontal support structure and the longitudinal support structure, and the included angle between the longitudinal section of the milling groove and the chamfered surface is an acute angle. After the horizontal support clipping part is filled in the milling groove, and the longitudinal support clipping part is filled in the milling groove, the engaging force of the horizontal support clipping part, the longitudinal support clipping part and the milling groove can be enhanced, and the friction force after the two clipping can be increased. The horizontal support covering part covers part of the assembly surface of the core plate, and the longitudinal support covering part covers part of the assembly surface of the core plate, so that the frame formed by the horizontal support structure and the longitudinal support structure can better cover the milling groove at the edge of the core plate. The cross section of the middle groove in the middle of the core board is also set to be trapezoidal. After the middle support embedding part is embedded in the middle groove with a trapezoidal cross section, the bite force and friction force can be greatly enhanced, and the middle support covering parts on both sides of the middle support structure respectively wrap the part of the assembly surface of the core board outside the middle groove, so that the middle support structure can better wrap the core board, effectively avoiding the quality problems of cracking and deformation of the door board in the middle position, improving the service life and product quality of the assembled door board with a narrow frame, and at the same time, the middle support structure can be set in the middle of the core board to play a better abutment and stabilization role for the longer longitudinal support structure. The end of the horizontal support embedding part away from the horizontal support covering part is flush with the edge of the short side of the core board, and the end of the longitudinal support embedding part away from the longitudinal support covering part is flush with the edge of the long side of the core board, which is conducive to ensuring the aesthetics of the overall door board, and can avoid the presence of a cracking point at the edge of the door board when the two are not flush or there is a protruding part. By setting the transverse sealing layer and the longitudinal sealing layer, external influencing factors such as water and oxygen can be prevented from entering the clamping gap between the core plate and the transverse brace clamping part and the longitudinal brace clamping part, which is beneficial to improve the assembly stability of the transverse brace structure, the longitudinal brace structure and the core plate. The triangular notch opened on the side of the longitudinal brace structure facing the central brace structure can increase the contact area of ​​the longitudinal brace structure and the central brace structure during assembly, improve the abutment stability of the central brace structure against the longer longitudinal brace structure, and further prevent the entire assembled door panel from deforming. The anti-deformation assembled door panel structure of the utility model is simple in structure and easy and quick to assemble. During assembly, it is only necessary to assemble and fix the milled core plate, the longitudinal brace structure, the transverse brace structure and the central brace structure, and then paint the product. While achieving the effect of an assembled door panel with a beautiful narrow frame, it can also improve the quality problems such as cracking and deformation of the door panel, which is beneficial to improving the service life and product quality of the product.
