Description

Technical Field

[0001] This invention relates to the field of furniture technology, and more specifically, to aluminum-framed glass doors with deformation correction functions. This invention can also be used for door panels and cabinets with deformation correction functions. Background Technology

[0002] In cabinet hinged doors, there is a type of hinge called top-bottom hinge (such as heavy-duty top-bottom hinges). This means that there is no hinge in the middle of the door panel; only one hinge (like a heavy-duty top-bottom hinge) is installed at the top and one at the bottom. This design optimizes the hinge layout, avoiding structural interference between the door panel and the shelves, while reducing the number of hinges and making the product look cleaner, aligning with minimalist design principles. However, this type of door panel is prone to deformation in the middle, mainly due to the following reasons: First, the hinges are only fixed to the top and bottom of the door panel, resulting in a lack of direct connection and effective support in the middle; second, the hinges occupy the frame cavity, forcing the glass core panel to shift outwards, causing the overall center of gravity of the door panel to shift outwards. When the door panel height exceeds a certain threshold (such as 2100mm), under its own weight, this unsupported structure with an outward-shifted center of gravity will experience significant outward deformation in the middle.

[0003] The prior art (application number: 201720430894.7, application date: 2018.05.04) discloses a cabinet with a straightening and correction structure. The solution includes a cabinet body and a cabinet door. An installation groove is recessed in the length direction of the cabinet door, and a straightener is installed in the installation groove. The cabinet door is hinged to one side of the cabinet body by three or more hinge structures. This solution cannot solve the problem of unstable center of gravity caused by the eccentric structure of the door panel.

[0004] In summary, the technical problems that urgently need to be solved in this field are as follows: Hinges occupy the frame cavity, forcing the glass core panel to move outward, causing the overall center of gravity of the door panel to shift outward. When the height of the door panel exceeds a certain threshold (such as 2100mm), under its own weight, this unsupported structure with an outward-shifted center of gravity will experience significant outward deformation in the middle position. Summary of the Invention

[0005] In view of this, the present invention provides a door panel with a deformation correction function to solve the problem that the hinge occupies the frame cavity, forcing the glass core to move outward, resulting in the overall center of gravity of the door panel being biased to the outside.

The groove of the core board left insertion groove 1112 faces the right side frame 13.

[0035] The right frame 13 includes a right straightening component 130, a right core plate groove 131, and a right vertical frame cavity 132. The right core plate groove 131 and the right vertical frame cavity 132 are integrally connected. The right straightening component 130 is snapped into the right vertical frame cavity 132. The right vertical frame cavity 132 includes a right frame front side plate 1321, a right frame inner side plate 1322, a right frame back side plate 1323, and a right frame outer side plate 1324 connected in sequence. The right frame front side plate 1321 and the right frame back side plate 1323 are arranged in parallel. The right frame inner side plate... 1322 and the outer side panel 1324 of the right frame are arranged parallel to each other. The right frame front side panel 1321, the right frame inner side panel 1322, the right frame back side panel 1323, and the right frame outer side panel 1324 form a rectangular frame for the right side panel. The right straightening component 130 includes a hollow rectangular right straightening body 1301, a rectangular upper right straightening plate 1302, a rectangular middle right straightening plate 1303, and a rectangular lower right straightening plate 1304. The upper right straightening plate 1302 and the lower right straightening plate 1304 are respectively connected to the right straightening body 1301. The head and tail ends are located near the core plate 2; the right middle straightening plate 1303 is connected to the middle of the right straightening body 1301 and is located away from the core plate 2; the right straightening body 1301, the right upper straightening plate 1302, the right middle straightening plate 1303, and the right lower straightening plate 1304 are all snapped into the rectangular frame of the right side plate; the right core plate groove 131 includes a right arc plate 1310 and a right baffle 1311, the concave surface of the right arc plate 1310 faces the right side frame front side plate 1321 and is located near the right side frame front side plate 1321. One end is integrally connected to the junction between the right side frame front panel 1321 and the right side frame outer panel 1324. One end of the right baffle 1311 is integrally connected to the right arc plate 1310. The other end of the right baffle 1311 is connected to the side of the right side frame front panel 1321 away from the right side frame back panel 1323. A C-shaped core plate right insertion groove 1312 is formed between part of the right arc plate 1310, the right baffle 1311 and part of the right side frame front panel 1321. The groove of the core plate right insertion groove 1312 faces the left side frame 11.

[0036] The core board 2 is located within the rectangular frame of the border. One side of the core board 2 is inserted into the left insertion slot 1112 of the core board, and the other side is inserted into the right insertion slot 1312 of the core board.

[0037] Specifically, refer to Figures 1 to 2 As shown, the door frame 1 is the skeleton of the door panel, responsible for load-bearing, shaping, and connection. The material of the door frame 1 can be solid wood (such as oak, walnut, cherry, maple, pine), MDF, multi-layer solid wood board, multi-layer plywood, or aluminum. In this embodiment, the door frame 1 is made of aluminum. The core board 2 is the board material filled inside the door frame 1, mainly serving a filling and stabilizing function. In this embodiment, the core board 2 is a glass core board.

[0038] The aforementioned left frame 11 is the left vertical component of the door panel, the top frame 12 is the top horizontal component of the door panel, the right frame 13 is the right vertical component of the door panel, and the bottom frame 14 is the bottom horizontal component of the door panel. The left frame 11, top frame 12, right frame 13, and bottom frame 14 together constitute the outer frame of the door panel. The parallel arrangement of the left frame 11 and right frame 13 ensures that the two sides of the door panel are vertical and parallel, which is the basis for the door panel to open and close vertically and smoothly. The parallel arrangement of the top frame 12 and bottom frame 14 ensures that the top and bottom of the door panel are horizontal and parallel, resulting in a neat appearance for the door panel.

[0039] The rectangular frame of the door frame has extremely high mechanical stability. The left frame 11, top frame 12, right frame 13, and bottom frame 14 are firmly connected end to end, forming a rigid load-bearing whole that can resist the torsional forces caused by daily opening and closing and squeezing, preventing the door panel from deforming or falling apart. The top hinge 3 and bottom hinge 4 can be directly installed on the top and bottom of the left frame 11 or the right frame 13. The weight of the entire door panel and the opening and closing force are borne by the rectangular frame of the door frame. This embodiment only illustrates the example of the top hinge 3 and bottom hinge 4 being directly installed on the top and bottom of the right frame 13.

[0040] Reference Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, the left frame 11 includes a left straightening member 110, a left core plate groove 111, and a left vertical frame cavity 112. The left straightening member 110 is used to prevent the left vertical frame cavity 112 from deforming away from the right frame 13. Since the left core plate groove 111 and the left vertical frame cavity 112 are integrally connected, stress concentration at the connection between the left core plate groove 111 and the left vertical frame cavity 112 can be avoided, the force flow is more continuous, and the overall load-bearing capacity and deformation resistance are generally stronger. After the left straightening member 110 is inserted into the left vertical frame cavity 112, it forms an interference fit with the left vertical frame cavity 112.

[0041] Reference Figure 3 , Figure 14 and Figure 15 As shown, the parallel arrangement of the left frame front side panel 1121 and the left frame back side panel 1123 ensures that the front and rear sides of the left vertical frame cavity 112 are horizontal and parallel; the parallel arrangement of the left frame inner side panel 1122 and the left frame outer side panel 1124 ensures that the inner and outer sides of the left vertical frame cavity 112 are vertical and parallel. The left frame front side panel 1121, the left frame inner side panel 1122, the left frame back side panel 1123, and the left frame outer side panel 1124 are firmly connected end to end, forming a rigid load-bearing whole that can resist the torsional force caused by daily opening and closing and squeezing, preventing the left vertical frame cavity 112 from deforming or falling apart.

[0042] Reference Figure 7 , Figures 9 to 13As shown, the left straightening component 110 includes a left straightening body 1101, a left upper straightening plate 1102, a left middle straightening plate 1103, and a left lower straightening plate 1104. The cross-sectional shape of the left straightening body 1101 along the direction from the left frame 11 to the right frame 13 is a square or rectangle. The shapes of the left upper straightening plate 1102, left middle straightening plate 1103, and left lower straightening plate 1104 are all cuboids. Along the direction from the upper frame 12 to the lower frame 14, the length extension direction of the left upper straightening plate 1102, left middle straightening plate 1103, and left lower straightening plate 1104 is the same as the length extension direction of the left straightening body 1101. The lengths of the left upper straightening plate 1102 and left lower straightening plate 1104 are both less than the length of the left middle straightening plate 1103. Along the direction from the left border 11 to the right border 13, the widths of the top left straight plate 1102, the middle left straight plate 1103, and the bottom left straight plate 1104 are the same. The widths of the upper left straightening plate 1102, the middle left straightening plate 1103, and the lower left straightening plate 1104 are the same as the width of the left straightening body 1101, and the width of the left straightening body 1101 is smaller than the width of the left hollow part 1125. For example, the width difference between the left hollow part 1125 and the left straightening body 1101 can be 0.5mm. This not only makes it easy to insert the left straightening component 110 into the left hollow part 1125, but also ensures that the left hollow part 1125 of the left frame 11 is evenly stressed due to the 0.5mm gap between the upper left straightening plate 1102, the middle left straightening plate 1103, and the lower left straightening plate 1104 and the left hollow part 1125, preventing the left frame 11 from twisting or deforming (such as twisting in a spiral shape) during the correction process.

[0043] The upper left straight plate 1102, middle left straight plate 1103, and lower left straight plate 1104 are made of low-carbon steel (such as ordinary carbon structural steel or low-alloy high-strength structural steel) or stainless steel. Ordinary carbon structural steel primarily uses iron and carbon, with a low carbon content (generally <0.25%) and low manganese content. Its core characteristic is that its strength is mainly derived from carbon content, with fewer alloying elements and lower cost. Low-alloy high-strength structural steel, based on ordinary carbon steel, adds a small amount (generally <3% in total) of alloying elements (such as Mn, Si, V, Nb, Ti, etc.). Its core characteristic is utilizing the grain refinement and precipitation strengthening effects of alloying elements to achieve higher strength and toughness with the same or lower carbon content. Stainless steel possesses excellent corrosion resistance, formability, and weldability.

[0044] Reference Figures 9 to 12As shown, the upper left straightening plate 1102 and the lower left straightening plate 1104 are welded to the head and tail ends of the left straightening body 1101, respectively, and the upper left straightening plate 1102 and the lower left straightening plate 1104 are closer to the core plate 2. The middle left straightening plate 1103 is welded to the middle of the left straightening body 1101, and the middle left straightening plate 1103 is away from the core plate 2. The upper left straightening plate 1102 and the lower left straightening plate 1104 are set on the same side. The upper left straightening plate 1102 and the lower left straightening plate 1104 are respectively set opposite to the middle left straightening plate 1103. It can be understood that the upper left straightening plate 1102 and the lower left straightening plate 1104 are located at the head end and tail end of the front side of the left straightening body 1101, respectively. The middle left straightening plate 1103 is located in the middle of the back side of the left straightening body 1101. That is, the upper left straightening plate 1102 and the middle left straightening plate 1103 are located on the front and rear sides of the left straightening body 1101, respectively. The lower left straightening plate 1104 and the middle left straightening plate 1103 are located on the front and rear sides of the left straightening body 1101, respectively. When assembling the left straightening component 110 with the left vertical frame cavity 112, first weld the upper left straightening plate 1102 and the lower left straightening plate 1104 to the front and rear ends of the left straightening body 1101, respectively. Weld the middle left straightening plate 1103 to the middle of the back side of the left straightening body 1101. After welding the upper left straightening plate 1102, middle left straightening plate 1103, and lower left straightening plate 1104 to the left straightening body 1101, first insert the upper left straightening plate 1102, welded to the left straightening body 1101, into the left hollow portion 1125 of the left side rectangular frame. The upper left straightening plate 1102 is placed closer to the core plate 2. Figure 9 (c) and Figure 10 As shown; secondly, when the left straightening body 1101 is inserted to the middle position near the left side plate rectangular frame, the left center straightening plate 1103 welded to the left straightening body 1101 begins to penetrate into the left hollow portion 1125 of the left side plate rectangular frame. After the left center straightening plate 1103 penetrates into the left hollow portion 1125, an interference fit is formed, as shown. Figure 9 (d) and Figure 11 As shown; when the left straightening body 1101 is inserted to the end position near the left side plate rectangular frame, the lower left straightening plate 1104 welded to the left straightening body 1101 begins to penetrate into the left hollow part 1125 of the left side plate rectangular frame, as shown. Figure 9 (e) and Figure 12 As shown.

[0045] The left center straightening plate 1103 in the left straightening component 110 applies a spring force pointing towards the back of the left side panel 1123 to the left hollow part 1125 of the left side panel rectangular frame, thereby counteracting the positive pressure caused by the center of gravity being off to the outside, and thus effectively correcting the problem of the door panel bending outward.

[0046] Continue to refer to Figure 3 and Figure 4As shown, the left core plate groove 111 includes a left arc-shaped plate 1110 and a left baffle 1111. The left arc-shaped plate 1110 is arc-shaped, with its concave surface facing the left side panel 1121. The left baffle 1111 is cuboid in shape, dividing the left arc-shaped plate 1110 into two parts. The left arc-shaped plate 1110, the left baffle 1111, and the left side panel 1121 together form a left side panel sector. Along the direction from the upper side panel 12 to the lower side panel 14, the cross-sectional shape of the left side panel sector is a right-angled sector. An angular arc is formed between the left baffle 1111 and the left side panel 1121. Along the direction from the upper side panel 12 to the lower side panel 14, the length extension direction of the left arc-shaped plate 1110 is the same as that of the left baffle 1111.

[0047] The left arc plate 1110, left baffle 1111, left side frame 1121 and left side frame 1124 are integrally connected. One end of the left baffle 1111 is integrally connected to the left arc plate 1110, and the other end of the left baffle 1111 is integrally connected to the side of the left side frame 1121 away from the left side frame back plate 1123. This effectively avoids stress concentration at the connection between the left core plate groove 111 and the left vertical frame cavity 112, resulting in more continuous force flow transmission and generally stronger overall load-bearing capacity and deformation resistance.

[0048] A chamfered core plate left insertion groove 1112 is formed between part of the left arc plate 1110, the left baffle 1111 and part of the left side frame 1121. The groove opening of the core plate left insertion groove 1112 faces the right frame 13, that is, the groove opening of the core plate left insertion groove 1112 faces the core plate 2. The chamfered core plate left insertion groove 1112 is used to insert the left side of the core plate 2. The core plate 2 is located in the rectangular frame of the frame. When the core plate 2 is assembled with the left vertical frame cavity 112, the left side of the core plate 2 is inserted into the core plate left insertion groove 1112.

[0049] Reference Figure 2 , Figure 5 , Figure 8 and Figure 13 As shown, the right frame 13 includes a right straightening component 130, a right core plate groove component 131, and a right vertical frame cavity 132. The right straightening component 130 is used to prevent the right vertical frame cavity 132 from deforming away from the left frame 11. Since the right core plate groove component 131 and the right vertical frame cavity 132 are integrally connected, stress concentration at the connection between the right core plate groove component 131 and the right vertical frame cavity 132 can be avoided, the force flow is more continuous, and the overall load-bearing capacity and deformation resistance are generally stronger. After the right straightening component 130 is inserted into the right vertical frame cavity 132, it is interference-fitted with the right vertical frame cavity 132.

[0050] The parallel arrangement of the right frame front side panel 1321 and the right frame back side panel 1323 ensures that the front and rear sides of the right vertical frame cavity 132 are horizontal and parallel; the parallel arrangement of the right frame inner side panel 1322 and the right frame outer side panel 1324 ensures that the inner and outer sides of the right vertical frame cavity 132 are vertical and parallel. The right frame front side panel 1321, right frame inner side panel 1322, right frame back side panel 1323, and right frame outer side panel 1324 are firmly connected end to end, forming a rigid load-bearing whole that can resist the torsional force caused by daily opening and closing and squeezing, preventing the right vertical frame cavity 132 from deforming or falling apart.

[0051] Reference Figure 8 and Figure 13 As shown, the right straightening component 130 includes a right straightening body 1301, a right upper straightening plate 1302, a right middle straightening plate 1303, and a right lower straightening plate 1304. The cross-sectional shape of the right straightening body 1301 along the direction from the left frame 11 to the right frame 13 is a square or a rectangle. The shapes of the right upper straightening plate 1302, right middle straightening plate 1303, and right lower straightening plate 1304 are all cuboids. Along the direction from the upper frame 12 to the lower frame 14, the length extension direction of the right upper straightening plate 1302, right middle straightening plate 1303, and right lower straightening plate 1304 is the same as the length extension direction of the right straightening body 1301. The lengths of the right upper straightening plate 1302 and right lower straightening plate 1304 can be the same as the length of the right straightening body 1301, or the lengths of the right upper straightening plate 1302 and right lower straightening plate 1304 can both be less than the length of the right straightening body 1301. Along the direction from the left border 11 to the right border 13, the widths of the upper right straight plate 1302, the middle right straight plate 1303, and the lower right straight plate 1304 are the same. The widths of the upper right straightening plate 1302, the middle right straightening plate 1303, and the lower right straightening plate 1304 are the same as the width of the right straightening body 1301, and the width of the right straightening body 1301 is smaller than the width of the right hollow part 1325. For example, the width difference between the right hollow part 1325 and the right straightening body 1301 can be 0.5mm. This not only makes it easier to insert the left straightening component 110 into the right hollow part 1325, but also ensures that the upper right straightening plate 1302, the middle right straightening plate 1303, and the lower right straightening plate 1304 have only a 0.5mm gap with the right hollow part 1325, so that the right hollow part 1325 of the right frame 13 is subjected to uniform force, preventing the right frame 13 from twisting or deforming (such as twisting in a spiral shape) during the correction process.

[0052] The upper right straight plate 1302, middle right straight plate 1303, and lower right straight plate 1304 are all made of low-carbon steel (such as ordinary carbon structural steel or low-alloy high-strength structural steel) or stainless steel. Ordinary carbon structural steel uses iron and carbon as the main elements, with a low carbon content (generally <0.25%) and low manganese content. Its core characteristic is that its strength is mainly obtained through carbon content, with fewer alloying elements and lower cost. Low-alloy high-strength structural steel, based on ordinary carbon steel, adds a small amount (generally <3% in total) of alloying elements (such as Mn, Si, V, Nb, Ti, etc.). Its core characteristic is that it utilizes the grain refinement and precipitation strengthening effects of alloying elements to achieve higher strength and toughness with the same or lower carbon content. Stainless steel has excellent corrosion resistance, formability, and weldability.

[0053] Reference Figure 8 and Figure 13 As shown, the upper right straightening plate 1302 and the lower right straightening plate 1304 are welded to the head and tail ends of the right straightening body 1301, respectively, and the upper right straightening plate 1302 and the lower right straightening plate 1304 are closer to the core plate 2. The middle right straightening plate 1303 is welded to the middle of the right straightening body 1301, and the middle right straightening plate 1303 is away from the core plate 2. The upper right straightening plate 1302 and the lower right straightening plate 1304 are set on the same side, and are respectively opposite to the middle right straightening plate 1303. This can be understood as follows: the upper right straightening plate 1302 and the lower right straightening plate 1304 are located at the head and tail ends of the front side of the right straightening body 1301, respectively; the middle right straightening plate 1303 is located in the middle of the back side of the right straightening body 1301. In other words, the upper right straightening plate 1302 and the middle right straightening plate 1303 are located on the front and rear sides of the right straightening body 1301, respectively, and the lower right straightening plate 1304 and the middle right straightening plate 1303 are located on the front and rear sides of the right straightening body 1301, respectively. The assembly method of the right straightening component 130 and the right vertical frame cavity 132 is the same as the assembly method of the left straightening component 110 and the left vertical frame cavity 122. For the assembly of the right straightening component 130 and the right vertical frame cavity 132, please refer to [the relevant documentation]. Figures 9 to 12As shown, when assembling the right straightening component 130 with the right vertical frame cavity 132, first weld the upper right straightening plate 1302 and the lower right straightening plate 1304 to the head and tail ends of the front side of the right straightening body 1301, and weld the middle right straightening plate 1303 to the middle of the back side of the right straightening body 1301. After welding the upper right straightening plate 1302, the middle right straightening plate 1303, and the lower right straightening plate 1304 to the right straightening body 1301, first insert the upper right straightening plate 1302 welded to the right straightening body 1301 into the right hollow part 1325 of the right side rectangular frame. 302 is placed near the core plate 2; next, when the right straightening body 1301 is inserted to the middle position near the right side plate rectangular frame, the right middle straightening plate 1303 welded to the right straightening body 1301 begins to be inserted into the right hollow part 1325 of the right side plate rectangular frame, and an interference fit is generated after the right middle straightening plate 1303 is inserted into the right hollow part 1325; when the right straightening body 1301 is inserted to the end position near the right side plate rectangular frame, the right lower straightening plate 1304 welded to the right straightening body 1301 begins to be inserted into the right hollow part 1325 of the right side plate rectangular frame.

[0054] The right center straightening plate 1303 in the right straightening component 130 applies a spring force pointing towards the back of the right frame back panel 1323 to the right hollow part 1325 of the right side panel rectangular frame, thereby counteracting the positive pressure caused by the center of gravity being off to the outside, and thus effectively correcting the problem of the door panel bending outward. The right core plate groove 131 includes a right arc-shaped plate 1310 and a right baffle 1311. The right arc-shaped plate 1310 is arc-shaped, with its concave surface facing the right side frame front plate 1321. The right baffle 1311 is cuboid in shape, dividing the right arc-shaped plate 1310 into two parts. The right arc-shaped plate 1310, the right baffle 1311, and part of the right side frame front plate 1321 together form a right side frame sector. Along the direction from the upper frame 12 to the lower frame 14, the cross-sectional shape of the right side frame sector is a right-angled sector. An angular arc is formed between the right baffle 1311 and part of the right side frame front plate 1321. Along the direction from the upper frame 12 to the lower frame 14, the length extension direction of the right arc-shaped plate 1310 is the same as that of the right baffle 1311.

[0055] The right arc plate 1310, right baffle 1311, right side frame front plate 1321 and right side frame outer plate 1324 are integrally connected. One end of the right baffle 1311 is integrally connected to the right arc plate 1310, and the other end of the right baffle 1311 is integrally connected to the side of the right side frame front plate 1321 away from the right side frame back plate 1323. This effectively avoids stress concentration at the connection between the right core plate groove 131 and the right vertical frame cavity 132, resulting in more continuous force flow transmission and generally stronger overall load-bearing capacity and deformation resistance.

[0056] Continue to refer to Figure 2 , Figure 5 and Figure 6 As shown, a chamfered core plate right insertion groove 1312 is formed between part of the right arc plate 1310, the right baffle 1311 and part of the right side frame front side plate 1321. The groove opening of the core plate right insertion groove 1312 faces the right side frame 13, that is, the groove opening of the core plate right insertion groove 1312 faces the core plate 2. The chamfered core plate right insertion groove 1312 is used to insert the right side of the core plate 2. The core plate 2 is located in the rectangular frame of the frame. When the core plate 2 is assembled with the right vertical frame cavity 132, the right side of the core plate 2 is inserted into the core plate right insertion groove 1312.

[0057] Compared with the prior art, the door panel with deformation correction function provided in this embodiment achieves at least the following beneficial effects:

[0058] First, the left center straightening plate 1103 in the left straightening component 110 applies a spring force pointing towards the back of the left frame back panel 1123 to the left hollow portion 1125 of the left side rectangular frame, and the right center straightening plate 1303 in the right straightening component 130 applies a spring force pointing towards the back of the right frame back panel 1323 to the right hollow portion 1325 of the right side rectangular frame. This counteracts the positive pressure caused by the outward shift of the center of gravity, effectively correcting the problem of the door panel bending outward. This solves the problem of hinges occupying the frame cavity, forcing the glass core panel to move outward, and causing the overall center of gravity of the door panel to shift outward. When the door panel height exceeds a certain threshold (e.g., 2100mm), under its own weight, this unsupported structure with an outward-shifted center of gravity will exhibit significant outward deformation in the middle position. Second, the left core plate groove 111 and the left vertical frame cavity 112 are integrally connected, and the right core plate groove 131 and the right vertical frame cavity 132 are integrally connected; the end of the left arc-shaped plate 1110 near the left side panel 1121 is integrally connected to the junction between the left side panel 1121 and the left outer side panel 1124; one end of the left baffle 1111 is integrally connected to the left arc-shaped plate 1110, and the other end of the left baffle 1111 is integrally connected to the side of the left side panel 1121 away from the left back panel 1123; the concave surface of the right arc-shaped plate 1310 faces the right side panel 1321. On the side, one end of the right baffle 1311 is integrally connected to the junction between the right side panel 1321 and the right side outer panel 1324. One end of the right baffle 1311 is integrally connected to the right arc plate 1310, and the other end of the right baffle 1311 is integrally connected to the side of the right side panel 1321 away from the right side back panel 1323. This effectively avoids stress concentration at the connection between the left core plate groove 111 and the left vertical frame cavity 112, as well as between the right core plate groove 131 and the right vertical frame cavity 132. The force flow is more continuous, and the overall load-bearing capacity and deformation resistance are generally stronger.

[0059] In one optional embodiment, a left side plate strain groove 1110a is provided on the side of the left frame front side plate 1121 corresponding to the left insertion slot 1112 of the core board away from the left frame back side plate 1123, and the left side plate strain groove 1110a is recessed away from the core board 2; a left baffle 1111 is provided on the side of the left side plate 1112 of the core board near the left insertion slot 1112 of the core board, and the left baffle strain groove 1111a is recessed away from the left insertion slot 1112 of the core board; a right side plate strain groove 1310a is provided on the side of the right frame front side plate 1321 corresponding to the right insertion slot 1312 of the core board away from the right frame back side plate 1323, and the right side plate strain groove 1310a is recessed towards the core board 2; a right baffle 1311 is provided on the side of the right side plate 1312 of the core board near the right insertion slot 1312 of the core board, and the right baffle strain groove is recessed away from the right insertion slot 1312 of the core board.

[0060] Specifically, refer to Figure 14 and Figure 15 As shown, a left side plate strain gauge 1110a is provided on the front side of the left frame side plate 1121 corresponding to the left insertion slot 1112 of the core plate. The cross-sectional shape of the left side plate strain gauge 1110a along the direction from the left frame 11 to the right frame 13 is trapezoidal or inverted triangular, and the left side plate strain gauge 1110a is recessed towards the core plate 2. The number of left side plate strain gauges 1110a can be at least two, and at least two left side plate strain gauges 1110a are arranged along the direction from the left frame 11 to the right frame 13. (Continue referring to...) Figure 15 As shown, a rectangular left baffle strain groove 1111a is provided on the side of the left baffle 1111 near the left insertion groove 1112 of the core plate. There are at least two left baffle strain grooves 1111a, and the at least two left baffle strain grooves 1111a are arranged along the thickness direction of the core plate 2.

[0061] Reference Figure 5 and Figure 17 As shown, a right side plate strain groove 1310a is provided on the front side of the right side frame plate 1321 corresponding to the right insertion groove 1312 of the core plate. The cross-sectional shape of the right side plate strain groove 1310a along the direction from the left frame 11 to the right frame 13 is trapezoidal or inverted triangle, and the right side plate strain groove 1310a is recessed towards the core plate 2. The number of right side plate strain grooves 1310a can be at least two, and the at least two right side plate strain grooves 1310a are arranged along the direction from the left frame 11 to the right frame 13. A rectangular right baffle strain groove (not shown in the figure) is provided on the side of the right baffle 1311 near the right insertion groove 1312 of the core plate. The number of right baffle strain grooves is at least two, and the at least two right baffle strain grooves are arranged along the thickness direction of the core plate 2.

[0062] The above scheme involves opening a left side plate strain groove 1110a and a left baffle strain groove 1111a on the left side frame 11. The principle is to guide the internal stress of the left side of the core plate 2 and the left side plate 1121 and the left baffle 1111 to the left side plate strain groove 1110a and the left baffle strain groove 1111a for release, thereby avoiding stress accumulation in key parts of the left side frame 11, thus preventing cracking and deformation, and protecting the integrity of the left side frame 11. A right side plate strain groove 1310a and a right baffle strain groove are provided on the right side frame 13. The principle is to guide the internal stress of the right side edge of the core plate 2 and the right side plate 1321 and right baffle 1311 of the right side frame to the right side plate strain groove 1310a and right baffle strain groove for release, avoiding stress accumulation in key parts of the right side frame 13, thereby preventing cracking and deformation and protecting the integrity of the right side frame 13. In addition, after the core plate 2 is installed into the core plate left insertion groove 1112 and core plate right insertion groove 1321, it fully fills the joint surface, forming a stronger adhesion and sealing effect. At the same time, the left side plate strain groove 1110a and left baffle strain groove 1111a, and the right side plate strain groove 1310a and right baffle strain groove can accommodate and limit the excess adhesive generated during the extrusion process, preventing it from overflowing to the visible outer surface, thereby reducing subsequent cleaning processes.

[0063] In one optional embodiment, along the direction from the upper frame 12 to the lower frame 14, the length of the left straightening body 1101 is less than the length of the left vertical frame cavity 112, and the length of the right straightening body 1301 is less than the length of the right vertical frame cavity 132. Specifically, along the direction from the upper frame 12 to the lower frame 14, the length difference between the left straightening body 1101 and the left vertical frame cavity 112 ranges from 190mm to 210mm, and the length difference between the right straightening body 1301 and the right vertical frame cavity 132 ranges from 190mm to 210mm. Using this scheme, the upper left corner code 15 and the lower left corner code 17 on both sides of the left frame 11, and the upper right corner code 16 and the lower right corner code 18 on both sides of the right frame 13 can be avoided.

[0064] In one optional embodiment, the left side rectangular frame has a left hollow portion 1125. The depth of the left hollow portion 1125 along the thickness direction of the core plate 2 is a1. The total thickness between the upper left straightening plate 1102 and the left straightening body 1101, the middle left straightening plate 1103 and the left straightening body 1101, and the lower left straightening plate 1104 and the left straightening body 1101 is b1, wherein a1 is greater than b1. The right side rectangular frame has a right hollow portion 1325. The depth of the right hollow portion 1325 along the thickness direction of the core plate 2 is a2. The total thickness between the upper right straightening plate 1302 and the right straightening body 1301, the middle right straightening plate 1303 and the right straightening body 1301, and the lower right straightening plate 1304 and the right straightening body 1301 is b2, wherein a2 is greater than b2.

[0065] Specifically, refer to Figure 14 As shown, in this embodiment, a1 can be 17mm and b1 can be 16.5mm. Along the thickness direction of the core plate 2, the thickness of the left straightening body 1101 is greater than the sum of the thicknesses of the upper left straightening plate 1102, the middle left straightening plate 1103 and the lower left straightening plate 1104. For example, along the thickness direction of the core plate 2, the thicknesses of the upper left straightening plate 1102, the middle left straightening plate 1103 and the lower left straightening plate 1104 can all be 2.5mm, and the thickness of the left straightening body 1101 can be 14mm. Along the thickness direction of the core plate 2, when the total thickness between the left center straightening plate 1103 and the left straightening body 1101 is 16.5mm, and an additional 2.5mm thickness is added to the left upper straightening plate 1102 or the left lower straightening plate 1104 (total thickness 19.5mm), it is greater than the depth of the left hollow part 1125 by 17mm. After the middle part of the left straightening body 1101 passes through the left hollow part 1125, an interference fit is formed. The left straightening piece 110 is inserted into the left hollow part 1125 of the left vertical frame cavity 112 to form a fastening effect. Furthermore, along the thickness direction of the core plate 2, the thickness of the left straightening body 1101 is 3mm less than the depth of the left hollow part 1125. This dimension can avoid friction between the left straightening body 1101 and the left hollow part 1125, making it easier to insert the left straightening piece 110; left upper straightening... The sum of the thicknesses of the straight plate 1102, the left-middle straight plate 1103 or the left-lower straight plate 1104 and the left straightening body 1101 is 0.5mm less than the thickness of the left hollow part 1125. However, when the left-upper straight plate 1102, the left-middle straight plate 1103 and the left-lower straight plate 1104 are integrated with the left straightening body 1101, their total thickness is 19mm (such as the sum of the thicknesses of the left straightening body 1101, the left-upper straight plate 1102 and the left-middle straight plate 1103, or the sum of the thicknesses of the left straightening body 1101, the left-lower straight plate 1104 and the left-middle straight plate 1103), which is 2mm larger than the size of the left hollow part 1125. As a result, the left straightening body 1101 will be squeezed into an arc shape in the left hollow part 1125, and the left straightening piece 110 will generate elasticity to counteract the deformation of the left frame 11. It should be noted that the data for a1 and b1 above can be adjusted according to the actual situation, and this embodiment does not impose specific limitations.

[0066] Reference Figure 17As shown, in this embodiment, a2 can be 17mm and b2 can be 16.5mm. Along the thickness direction of the core plate 2, the thickness of the right straightening body 1301 is greater than the sum of the thicknesses of the upper right straightening plate 1302, the middle right straightening plate 1303 and the lower right straightening plate 1304. For example, along the thickness direction of the core plate 2, the thicknesses of the upper right straightening plate 1302, the middle right straightening plate 1303 and the lower right straightening plate 1304 can all be 2.5mm, and the thickness of the right straightening body 1301 can be 14mm. Along the thickness direction of the core plate 2, when the total thickness between the right center straightening plate 1303 and the right straightening body 1301 is 16.5mm, and an additional 2.5mm thickness is added to the upper right straightening plate 1302 or the lower right straightening plate 1304 (total thickness 19.5mm), it is greater than the depth of the right hollow portion 1325 (17mm). After the middle part of the right straightening body 1301 passes through the right hollow portion 1325, an interference fit is formed. The right straightening component 130 is inserted into the left hollow portion 1125 of the right vertical frame cavity 132 to form a fastening effect (specifically, refer to the left straightening component 110 being inserted into the left hollow portion 1125 of the left vertical frame cavity 112 to form a fastening effect, which will not be repeated here). It should be noted that the data of a2 and b2 above can be adjusted according to the actual situation, and this embodiment does not impose specific limitations.

[0067] In one alternative embodiment, combined with Figure 9 and Figure 14 As shown, along the thickness direction of the core board 2, the total thickness between the upper left straightening plate 1102 and the left straightening body 1101, between the middle left straightening plate 1103 and the left straightening body 1101, and between the lower left straightening plate 1104 and the left straightening body 1101 ranges from 16mm to 16.5mm; along the direction from the upper frame 12 to the lower frame 14, the lengths of the upper left straightening plate 1102, the middle left straightening plate 1103, and the lower left straightening plate 1104 range from 50mm to 70mm. m; along the thickness direction of the core board 2, the total thickness between the upper right straightening plate 1302 and the right straightening body 1301, between the middle right straightening plate 1303 and the right straightening body 1301, and between the lower right straightening plate 1304 and the right straightening body 1301 ranges from 16mm to 16.5mm; along the direction from the upper frame 12 to the lower frame 14, the lengths of the upper right straightening plate 1302, the middle right straightening plate 1303, and the lower right straightening plate 1304 range from 50mm to 70mm.

[0068] Specifically, along the thickness direction of the core plate 2, when the total thickness between the upper left straightening plate 1102 and the left straightening body 1101, between the middle left straightening plate 1103 and the left straightening body 1101, and between the lower left straightening plate 1104 and the left straightening body 1101 is too thick, the left straightening component 110 cannot be inserted into the left hollow portion 1125; .... When the total thickness between 01 is too thin, the deformation of the left frame 11 cannot be corrected. Therefore, in this embodiment, the total thickness range between the upper left straightening plate 1102 and the left straightening body 1101, the middle left straightening plate 1103 and the left straightening body 1101, and the lower left straightening plate 1104 and the left straightening body 1101 along the thickness direction of the core plate 2 is designed to be 16mm to 16.5mm. This solution not only allows the left straightening piece 110 to be inserted into the left hollow part 1125, but also corrects the deformation of the left frame 11. Specifically, along the thickness direction of the core board 2, the total thickness b1 between the upper left straightening plate 1102 and the left straightening body 1101, between the middle left straightening plate 1103 and the left straightening body 1101, and between the lower left straightening plate 1104 and the left straightening body 1101 can be 16mm, 16.3mm, or 16.5mm. Specifically, when the height of the door panel is less than 2400mm, b1 can be 16mm; when the height of the door panel is greater than 2400mm and less than 2700mm, b1 can be 16.5mm.

[0069] Along the direction from the upper frame 12 to the lower frame 14, if the lengths of the upper left straightening plate 1102, the middle left straightening plate 1103, and the lower left straightening plate 1104 are too short, the contact area between the upper left straightening plate 1102, the middle left straightening plate 1103, and the lower left straightening plate 1104 and the left straightening body 1101 will be small, thus affecting the welding of the upper left straightening plate 1102, the middle left straightening plate 1103, and the lower left straightening plate 1104 to the left straightening body 1101. The small contact area results in the left straightening piece 110 being unstable. If the lengths of the upper left straightening plate 1102, the middle left straightening plate 1103, and the lower left straightening plate 1104 are too long, the left straightening piece 110 and the left hollow part 1125 will have a larger contact area, increasing the friction between them. This makes it difficult for the left straightening piece 110 to be inserted into the left hollow part 1125. Therefore, along the upper frame 12 pointing to the lower frame 1... In direction 4, the lengths of the upper left straightening plate 1102, the middle left straightening plate 1103, and the lower left straightening plate 1104 are designed to range from 50mm to 70mm. This design not only increases the contact area between the upper left straightening plate 1102, the middle left straightening plate 1103, and the lower left straightening plate 1104 and the left straightening body 1101, but also maximizes the contact area between the upper left straightening plate 1102, the middle left straightening plate 1103, and the lower left straightening plate 1104 and the left straightening body 1101. The welding area with the left straightening body 1101 increases, thus making the connection between the upper left straightening plate 1102 and the left straightening body 1101, the middle left straightening plate 1103 and the left straightening body 1101, and the lower left straightening plate 1104 and the left straightening body 1101 more secure. This also reduces the friction between the left straightening piece 110 and the left hollow portion 1125, making it easier for the left straightening piece 110 to be inserted into the left hollow portion 1125. Specifically, along the direction from the upper frame 12 to the lower frame 14, the lengths of the upper left straightening plate 1102, the middle left straightening plate 1103, and the lower left straightening plate 1104 can be 50mm, 55mm, 60mm, 65mm, or 70mm.

[0070] Along the thickness direction of the core board 2, when the total thickness between the upper right straightening plate 1302 and the right straightening body 1301, between the middle right straightening plate 1303 and the right straightening body 1301, and between the lower right straightening plate 1304 and the right straightening body 1301 is too thick, the right straightening component 130 cannot be inserted into the right hollow portion 1325; when the total thickness between the upper right straightening plate 1302 and the right straightening body 1301, between the middle right straightening plate 1303 and the right straightening body 1301, and between the lower right straightening plate 1304 and the right straightening body 1301 is too thick, the right straightening component 130 cannot be inserted into the right hollow portion 1325; When the total thickness between them is too thin, the deformation of the right frame 13 cannot be corrected. Therefore, in this embodiment, the total thickness range between the upper right straightening plate 1302 and the right straightening body 1301, the middle right straightening plate 1303 and the right straightening body 1301, and the lower right straightening plate 1304 and the right straightening body 1301 along the thickness direction of the core plate 2 is designed to be 16mm to 16.5mm. This scheme not only allows the right straightening component 130 to be inserted into the right hollow portion 1325, but also corrects the deformation of the right frame 13. Specifically, the total thickness b2 between the upper right straightening plate 1302 and the right straightening body 1301, the middle right straightening plate 1303 and the right straightening body 1301, and the lower right straightening plate 1304 and the right straightening body 1301 along the thickness direction of the core plate 2 can be 16mm, 16.3mm, or 16.5mm.

[0071] Along the direction from the upper frame 12 to the lower frame 14, if the lengths of the upper right straightening plate 1302, the middle right straightening plate 1303, and the lower right straightening plate 1304 are too short, the contact area between the upper right straightening plate 1302, the middle right straightening plate 1303, and the lower right straightening plate 1304 and the right straightening body 1301 will be small, thus affecting the welding of the upper right straightening plate 1302, the middle right straightening plate 1303, and the lower right straightening plate 1304 to the right straightening body 1301. The small contact area results in the right straightening component 130 being unstable. If the lengths of the upper right straightening plate 1302, the middle right straightening plate 1303, and the lower right straightening plate 1304 are too long, the right straightening component 130 and the right hollow part 1325 will have a larger contact area, increasing the friction between them. This makes it difficult for the right straightening component 130 to be inserted into the right hollow part 1325. Therefore, along the upper frame 12 pointing to the lower frame 1... In direction 4, the lengths of the upper right straightening plate 1302, the middle right straightening plate 1303, and the lower right straightening plate 1304 are designed to range from 50mm to 70mm. This design not only increases the contact area between the upper right straightening plate 1302, the middle right straightening plate 1303, and the lower right straightening plate 1304 and the right straightening body 1301, but also maximizes the contact area between the upper right straightening plate 1302, the middle right straightening plate 1303, and the lower right straightening plate 1304 and the right straightening body 1301. The welding area with the right straightening body 1301, and consequently the connection between the upper right straightening plate 1302 and the right straightening body 1301, the middle right straightening plate 1303 and the right straightening body 1301, and the lower right straightening plate 1304 and the right straightening body 1301, is more secure. This also reduces the friction between the right straightening component 130 and the right hollow portion 1325, making it easier for the right straightening component 130 to be inserted into the right hollow portion 1325. Specifically, along the direction from the upper frame 12 to the lower frame 14, the lengths of the upper right straightening plate 1302, the middle right straightening plate 1303, and the lower right straightening plate 1304 can be 50mm, 55mm, 60mm, 65mm, or 70mm.

[0072] In one alternative embodiment, continue to refer to Figure 7 , Figure 8 , Figure 14 , Figure 16 and Figure 17As shown, the left straightening body 1101 includes a left straightening front side plate 1101a, a left straightening outer side plate 1101b, a left straightening back side plate 1101c, and a left straightening inner side plate 1101d connected in sequence. The left straightening front side plate 1101a and the left straightening back side plate 1101c are arranged parallel to each other, and the left straightening outer side plate 1101b and the left straightening inner side plate 1101d are arranged parallel to each other. The left straightening front side plate 1101a, the left straightening outer side plate 1101b, the left straightening back side plate 1101c, and the left straightening inner side plate 1101d form a left straightening rectangular frame. The upper left straightening plate 1102 and the lower left straightening plate 1104 are connected. The left straightening front side plate 1101a is connected to the head and tail ends on the side away from the left straightening back side plate 1101c. The left middle straightening plate 1103 is connected to the middle part of the side of the left straightening back side plate 1101c away from the left straightening front side plate 1101a. The left straightening front side plate 1101a is parallel to the left frame front side plate 1121. The left straightening front side plate 1101a is closer to the left frame front side plate 1121. The left straightening back side plate 1101c is closer to the left frame back side plate 1123. The left straightening outer side plate 1101b is in contact with the left frame outer side plate 1124. The left straightening inner side plate 1101d is in contact with the left frame inner side plate 1122. The right straightening body 1301 includes a right straightening front side plate 1301a, a right straightening outer side plate 1301b, a right straightening back side plate 1301c, and a right straightening inner side plate 1301d connected in sequence. The right straightening front side plate 1301a and the right straightening back side plate 1301c are arranged in parallel, and the right straightening outer side plate 1301b and the right straightening inner side plate 1301d are arranged in parallel. The right straightening front side plate 1301a, the right straightening outer side plate 1301b, the right straightening back side plate 1301c, and the right straightening inner side plate 1301d form a right straightening rectangular frame. The upper right straightening plate 1302 and the lower right straightening plate 1304 are connected. At the head and tail ends of the right straightening front side plate 1301a on the side away from the right straightening back side plate 1301c, the right middle straightening plate 1303 is connected to the middle of the right straightening back side plate 1301c on the side away from the right straightening front side plate 1301a; the right straightening front side plate 1301a is parallel to the right side frame front side plate 1321, the right straightening front side plate 1301a is close to the right side frame front side plate 1321, the right straightening back side plate 1301c is close to the right side frame back side plate 1323, the right straightening outer side plate 1301b is in contact with the right side frame outer side plate 1324, and the right straightening inner side plate 1301d is in contact with the right side frame inner side plate 1322.

[0073] Specifically, refer to Figure 14As shown, the left straightening front side plate 1101a, left straightening outer side plate 1101b, left straightening back side plate 1101c, and left straightening inner side plate 1101d are integrally connected. The parallel arrangement of the left straightening front side plate 1101a and left straightening back side plate 1101c ensures that the front and rear sides of the left straightening body 1101 are horizontal and parallel; the parallel arrangement of the left straightening inner side plate 1101d and left straightening outer side plate 1101b ensures that the inner and outer sides of the left straightening body 1101 are vertical and parallel. The left straightening front side plate 1101a, left straightening outer side plate 1101b, left straightening back side plate 1101c, and left straightening inner side plate 1101d are firmly connected end to end to form a left straightening rectangular frame. This left straightening rectangular frame is a rigid load-bearing whole, which can resist the torsional force caused by daily opening and closing and compression, and prevent the left straightening component 110 from deforming or falling apart.

[0074] The upper left straightening plate 1102 and the lower left straightening plate 1104 are welded to the head and tail ends of the left straightening front side plate 1101a on the side away from the left straightening back side plate 1101c. The side of the upper left straightening plate 1102 away from the lower left straightening plate 1104 and the side of the lower left straightening plate 1104 away from the upper left straightening plate 1102 are respectively flush with the head and tail ends of the left straightening front side plate 1101a, so as to avoid affecting the installation of the upper left corner bracket 15 and the lower left corner bracket 17, thereby increasing the fastening connection between the left frame 11 and the upper frame 12 and between the left frame 11 and the lower frame 14. The left center straightening plate 1103 is welded to the middle of the left straightening back side plate 1101c away from the left straightening front side plate 1101a. During use, the left center straightening plate 1103 is squeezed by the left hollow part 1125 in the rectangular frame of the left side plate, which causes the left straightening part 110 to deform and form an elastic force supporting the back of the door panel, thereby offsetting the pressure on the front of the door panel caused by the center of gravity being off to the outside.

[0075] The left straightening front side panel 1101a, the left frame front side panel 1121, and the left straightening rear side panel are arranged in parallel. The left straightening front side panel 1101a is close to the left frame front side panel 1121. The upper left straightening panel 1102 and the lower left straightening panel 1104 are opposite to the left straightening front side panel 1101a and are in contact with the left frame front side panel 1121. The left straightening rear side panel 1101c is close to the left frame rear side panel 1123. The left middle straightening panel 1103 is opposite to the left straightening rear side panel 1101c and is in contact with the left frame rear side panel 1123. The left straightening outer side panel 1101b is in contact with the left frame outer side panel 1124. The left straightening inner side panel 1101d is in contact with the left frame inner side panel 1122.

[0076] Continue to refer to Figure 17As shown, the right straightening front side plate 1301a, right straightening outer side plate 1301b, right straightening back side plate 1301c, and right straightening inner side plate 1301d are integrally connected. The parallel arrangement of the right straightening front side plate 1301a and right straightening back side plate 1301c ensures that the front and rear sides of the right straightening body 1301 are horizontal and parallel; the parallel arrangement of the right straightening inner side plate 1301d and right straightening outer side plate 1301b ensures that the inner and outer sides of the right straightening body 1301 are vertical and parallel. The right straightening front side plate 1301a, right straightening outer side plate 1301b, right straightening back side plate 1301c, and right straightening inner side plate 1301d are firmly connected end-to-end, forming a right straightening rectangular frame. This right straightening rectangular frame is a rigid load-bearing whole, capable of resisting the torsional forces caused by daily opening and closing and compression, preventing the right straightening component 130 from deforming or falling apart.

[0077] The upper right straightening plate 1302 and the lower right straightening plate 1304 are welded to the head and tail ends of the right straightening front side plate 1301a on the side away from the right straightening back side plate 1301c. The side of the upper right straightening plate 1302 away from the lower right straightening plate 1304 and the side of the lower right straightening plate 1304 away from the upper right straightening plate 1302 are respectively flush with the head and tail ends of the right straightening front side plate 1301a, so as to avoid affecting the installation of the upper right corner bracket 16 and the lower right corner bracket 18, thereby increasing the fastening connection between the right side frame 13 and the upper frame 12 and between the right side frame 13 and the lower frame 14. The right center straightening plate 1303 is welded to the middle of the right straightening back side plate 1301c away from the right straightening front side plate 1301a. During use, the right center straightening plate 1303 is squeezed by the right hollow part 1325 in the right side plate rectangular frame, which causes the right straightening part 130 to deform and form an elastic force supporting the back of the door panel, thereby offsetting the pressure on the front of the door panel caused by the center of gravity being off to the outside.

[0078] The right straightening front side panel 1301a, the right side frame front side panel 1321, and the right straightening rear side panel are arranged in parallel. The right straightening front side panel 1301a is close to the right side frame front side panel 1321. The upper right straightening panel 1302 and the lower right straightening panel 1304 are opposite to the right straightening front side panel 1301a and are in contact with the right side frame front side panel 1321. The right straightening rear side panel 1301c is close to the right side frame rear side panel 1323. The right middle straightening panel 1303 is opposite to the right straightening rear side panel 1301c and is in contact with the right side frame rear side panel 1323. The right straightening outer side panel 1301b is in contact with the right side frame outer side panel 1324. The right straightening inner side panel 1301d is in contact with the right side frame inner side panel 1322.

[0079] With the above scheme, the overall structure of the left straightening body 1101 is simple and easy to process and manufacture. This not only helps to reduce the assembly complexity of the upper left straightening plate 1102, the middle left straightening plate 1103, and the lower left straightening plate 1104 with the left straightening body 1101, but also facilitates the installation of the left straightening component 110 to the left hollow part 1125 of the left side plate rectangular frame. The overall structure of the right straightening body 1301 is simple and easy to process and manufacture. This not only helps to reduce the assembly complexity of the upper right straightening plate 1302, the middle right straightening plate 1303, and the lower right straightening plate 1304 with the right straightening body 1301, but also facilitates the installation of the right straightening component 130 to the right hollow part 1325 of the right side plate rectangular frame.

[0080] In one alternative embodiment, continue to refer to Figure 2 , Figure 7 , Figure 8 , Figure 3 and Figure 5 As shown, rectangular left corner notches (not marked in the figure) are provided at both ends of the inner side panel 1122 of the left frame. The left corner notches penetrate the inner side panel 1122 of the left frame along the direction from the left frame 11 to the left frame 11. Rectangular right corner notches 1322a are provided at both ends of the inner side panel 1322 of the right frame. The right corner notches 1322a penetrate the inner side panel 1322 of the right frame along the direction from the left frame 11 to the right frame 13. J-shaped vertical notches 1323a of the right hinge are provided at both ends of the back side panel 1323 of the right frame. The vertical notches 1323a of the right hinge penetrate the back side panel 1323 of the right frame along the thickness direction of the core board 2. The right corner notches 1322a and the vertical notches 1323a of the right hinge are connected.

[0081] Specifically, the aforementioned left corner notch is used to precisely locate the connection between the horizontal component 151 and the vertical component 152 in the upper left corner code 15 and the lower left corner code 17, pointing from the left border 11 to the right border 13. The orthographic projection of the left corner notch does not overlap with the orthographic projection of the left straightening component 110. The aforementioned right corner notch 1322a is used to precisely locate the connection between the horizontal component 151 and the vertical component 152 in the upper right corner code 16 and the lower right corner code 18, pointing from the left border 11 to the right border 13. The orthographic projection of the right corner notch 1322a does not overlap with the orthographic projection of the right straightening component 130.

[0082] The right frame back panel 1323 has J-shaped vertical notches 1323a at both ends. The vertical notches 1323a are used to accurately position the top hinge 3 and the bottom hinge 4. The vertical notches 1323a penetrate the right frame back panel 1323 along the thickness direction of the core board 2. The right corner notch 1322a is connected to the vertical notch 1323a.

[0083] Using the above solution, not only can the top left corner code 15, bottom left corner code 17, top right corner code 16 and bottom right corner code 18 be installed quickly and easily, and the left border 11 and top border 12, the top border 12 and right border 13, the right border 13 and bottom border 14, and the bottom border 14 and left border 11 be securely connected, but the top hinge 3 and bottom hinge 4 can also be installed and adjusted quickly.

[0084] In one alternative embodiment, continue to refer to Figures 2 to 6 As shown, the upper frame 12 includes an upper horizontal frame cavity 121, which has a hollow portion 1211 extending along the left frame 11 towards the right frame 13; the lower frame 14 includes a lower horizontal frame cavity 141, which has a hollow portion 1411 extending along the left frame 11 towards the right frame 13; the door frame 1 also includes an L-shaped upper left corner bracket 15, upper right corner bracket 16, lower left corner bracket 17, and lower right corner bracket 18; the hollow portion 1211 of the upper horizontal frame is close to the rectangular frame of the left side panel. A left-side corner code 15 is inserted on the side of the left side panel rectangular frame near the hollow part 1211 of the upper horizontal frame; a right-side corner code 16 is inserted on the side of the upper horizontal frame rectangular frame near the right side panel rectangular frame near the hollow part 1211 of the upper horizontal frame; a left-side corner code 17 is inserted on the side of the lower horizontal frame rectangular frame near the left side panel rectangular frame near the hollow part 1411 of the lower horizontal frame; a right-side corner code 18 is inserted on the side of the lower horizontal frame rectangular frame near the right side panel rectangular frame near the hollow part 1411 of the lower horizontal frame.

[0085] Specifically, the upper frame 12 includes an upper horizontal frame cavity 121, which has a hollow portion 1211 extending from the left side to the right side along the direction from the left frame 11 to the right frame 13. During installation, the upper left corner bracket 15 and the lower right corner bracket 18 are inserted into the two ends of the hollow portion 1211 to connect the upper frame 12 with the left frame 11 and the upper frame 12 with the right frame 13.

[0086] The lower frame 14 includes a lower horizontal frame cavity 141, which has a hollow portion 1411 extending from the left side to the right side along the direction from the left frame 11 to the right frame 13. During installation, the lower left corner bracket 17 and the lower right corner bracket 18 are inserted into the beginning and end ends of the hollow portion 1411 to connect the lower frame 14 with the left frame 11 and the lower frame 14 with the right frame 13.

[0087] The rectangular frame of the border is connected by the upper left corner code 15, the upper right corner code 16, the lower left corner code 17, and the lower right corner code 18. During installation, the horizontal pieces 151 of the upper left corner code 15, the upper right corner code 16, the lower left corner code 17, and the lower right corner code 18 are respectively inserted into the hollow parts 1211 of the upper horizontal frame at both ends of the upper horizontal frame cavity 121 and the hollow parts 1411 of the lower horizontal frame at both ends of the upper horizontal frame cavity 121. Then, the left side plate rectangular frame and the right side plate rectangular frame are aligned with the vertical pieces 152 of the upper left corner code 15, the upper right corner code 16, the lower left corner code 17, and the lower right corner code 18. The vertical pieces 152 of the upper left corner code 15, the upper right corner code 16, the lower left corner code 17, and the lower right corner code 18 are respectively inserted vertically into the left side plate rectangular frame and the right side plate rectangular frame.

[0088] Through the above scheme, the upper left corner code 15, upper right corner code 16, lower left corner code 17, and lower right corner code 18 form a rigid node at the right-angle intersection of the rectangular frame. The force on the door panel (such as the downward force), the stress of the rectangular frame itself, and the external impact force can be effectively transferred and dispersed through the upper left corner code 15, upper right corner code 16, lower left corner code 17, and lower right corner code 18 between the upper frame 12 and the left frame 11, between the upper frame 12 and the right frame 13, between the lower frame 14 and the left frame 11, and between the lower frame 14 and the right frame 13, thus avoiding stress concentration at the fragile ends of the rectangular frame.

[0089] The top-left corner code 15, top-right corner code 16, bottom-left corner code 17, and bottom-right corner code 18 are all L-shaped. As long as the ends of the top frame 12, left frame 11, bottom frame 14, and right frame 13 are cut flat, inserting the top-left corner code 15, top-right corner code 16, bottom-left corner code 17, and bottom-right corner code 18 will naturally ensure that each corner of the rectangular frame is a precise right angle, thus ensuring the squareness of the entire rectangular frame. This is the foundation for a flat door panel and uniform gaps. In addition, the top-left corner code 15, top-right corner code 16, bottom-left corner code 17, and bottom-right corner code 18 are all hidden inside the rectangular frame to enhance the aesthetics of the door panel.

[0090] In one alternative embodiment, continue to refer to Figures 2 to 6As shown, the upper left corner bracket 15, upper right corner bracket 16, lower left corner bracket 17, and lower right corner bracket 18 all include a horizontal component 151 and a vertical component 152 integrally connected to the horizontal component 151; the vertical component 152 has a corner bracket vertical groove 1521 on the side near the horizontal component 151, and the groove opening of the corner bracket vertical groove 1521 faces the left frame back panel 1123 or the right frame back panel 1323; the horizontal component 151 has a corner bracket horizontal groove 1511 on the side near the vertical component 152, and the corner bracket horizontal groove 1511 intersects perpendicularly with the corner bracket vertical groove 1521 and connects to form an L-shaped corner bracket groove; a top hinge 3 is installed in the L-shaped corner bracket groove of the upper right corner bracket 16, and a bottom hinge 4 is installed in the L-shaped corner bracket groove of the lower right corner bracket 18; a hollow cylindrical vertical threaded hole 1522 is provided on the side of the vertical component 152 away from the horizontal component 151, and the left frame back panel 1123 faces the horizontal component 151. Both the 23 and the right frame back side plate 1323 are provided with side plate threaded holes 1323b that match the vertical threaded holes 1522. The left frame back side plate 1123 and the vertical member 152, as well as the right frame back side plate 1323 and the vertical member 152, are connected by vertical bolts 5. The vertical bolts 5 pass through the side plate threaded holes 1323b and are screwed into the vertical threaded holes 1522. The horizontal member 151 is provided with a hollow cylindrical horizontal threaded hole 1512 on the side away from the vertical member 152. The upper horizontal frame cavity 121 and the lower horizontal frame cavity 141 are provided with horizontal cavity threaded holes 1212 that match the horizontal threaded holes 1512. The upper horizontal frame cavity 121 and the horizontal member 151, as well as the lower horizontal frame cavity 141 and the horizontal member 151, are connected by horizontal bolts 6. The horizontal bolts 6 pass through the horizontal cavity threaded holes 1212 and are screwed into the horizontal threaded holes 1512.

[0091] Specifically, the assembly method of the door panel is as follows: Figure 18 As shown in (h) to (k), first connect the left border 11, top border 12, right border 13, and bottom border 14 using the top left corner code 15, top right corner code 16, bottom left corner code 17, and bottom right corner code 18, and insert the core board 2 in the middle, as follows. Figure 18 As shown in (h); after securing the four corners of the left frame 11, top frame 12, right frame 13, and bottom frame 14 with vertical bolts 5 and horizontal bolts 6, install the top hinge 3 and bottom hinge 4, as follows. Figure 18 As shown in (j); the vertical bolt 5 and the horizontal bolt 6 fix the top hinge 3 and the bottom hinge 4 into the horizontal grooves 1511 of the upper right corner bracket 16 and the lower right corner bracket 18, as shown. Figure 18 (k) Figure 5 and Figure 6 As shown.

[0092] Reference Figures 2 to 6As shown, the horizontal component 151 and the vertical component 152 are integrally bent and formed, and the horizontal component 151 and the vertical component 152 form an L-shaped structure. The vertical groove 1521 of the corner brackets of the upper right corner bracket 16 and the lower right corner bracket 18 is used to accommodate the vertical hinge cups of the top hinge 3 and the bottom hinge 4 (not marked in the figure). The horizontal groove 1511 of the corner brackets of the upper right corner bracket 16 and the lower right corner bracket 18 is used to accommodate the horizontal hinge cups of the top hinge 3 and the bottom hinge 4 (not marked in the figure).

[0093] The rear side plate of the upper horizontal frame cavity 121 near the right side frame 13 and the rear side plate of the lower horizontal frame cavity 141 near the right side frame 13 are both provided with a horizontal notch for the right hinge (not marked in the figure). The horizontal notch for the right hinge and the vertical notch for the right hinge 1323a intersect perpendicularly to form an L-shaped hinge notch. Along the thickness direction of the core board 2, the vertical grooves 1521 of the upper right corner bracket 16 and the lower right corner bracket 18 correspond to the vertical notch 1323a of the right hinge, respectively. The horizontal grooves 1511 of the upper right corner bracket 16 and the lower right corner bracket 18 correspond to the horizontal notch of the right hinge, respectively. The top hinge 3 and the bottom hinge 4 are installed in the L-shaped corner bracket groove through the L-shaped hinge notch. When the top hinge 3 is installed on the upper frame 12 and the right frame 13, and the bottom hinge 4 is installed on the lower frame 14 and the right frame 13, the vertical hinge cups of the top hinge 3 and the bottom hinge 4 are placed in the vertical groove 1521 of the corner bracket through the vertical notch 1323a of the right hinge, and the horizontal hinge cups of the top hinge 3 and the bottom hinge 4 are placed in the horizontal groove 1511 of the corner bracket through the horizontal notch of the right hinge.

[0094] The vertical member 152 has a hollow cylindrical vertical threaded hole 1522 on the side away from the horizontal member 151. There can be at least two vertical threaded holes 1522, which are arranged along the direction from the upper frame 12 to the lower frame 14. In this embodiment, there are four vertical threaded holes 1522. The left frame back side plate 1123 and the right frame back side plate 1323 are both provided with side plate threaded holes 1323b that are aligned with the vertical threaded holes 1522. The vertical bolt 5 passes through the side plate threaded hole 1323b and is screwed into the vertical threaded hole 1522 of the vertical member 152 from the outside to the inside, thereby tightening and fixing the upper left corner bracket 15, upper right corner bracket 16, lower left corner bracket 17, and lower right corner bracket 18 to the left frame 11 and the right frame 13, respectively.

[0095] A hollow cylindrical horizontal threaded hole 1512 is provided on the side of the horizontal component 151 away from the vertical component 152. The number of horizontal threaded holes 1512 can be at least two, and the at least two horizontal threaded holes 1512 are arranged along the direction from the left frame 11 to the right frame 13. In this embodiment, the number of horizontal threaded holes 1512 is four. Horizontal cavity threaded holes 1212 are provided on both the upper horizontal frame cavity 121 and the lower horizontal frame cavity 141. The horizontal cavity threaded holes 1212 are aligned with the horizontal threaded holes 1512. The horizontal bolt 6 passes through the horizontal cavity threaded hole 1212 and is screwed into the horizontal threaded hole 1512 of the horizontal component 151 from the outside to the inside, thereby tightening and fixing the upper left corner bracket 15, upper right corner bracket 16, lower left corner bracket 17, and lower right corner bracket 18 to the upper frame 12 and the lower frame 14, respectively.

[0096] The above solution provides several advantages. First, it offers strong resistance to shearing and tensile forces: horizontal bolts resist the downward shearing force generated by the load on the upper frame 12 and lower frame 14. Vertical bolts resist the tensile separation force between the left frame 11 and the upper and lower frames 12 and 14, and between the right frame 13 and the upper and lower frames 12 and 14. Second, the integrally formed upper left corner bracket 15, upper right corner bracket 16, lower left corner bracket 17, and lower right corner bracket 18 organically combine and disperse the forces along the direction from the left frame 11 to the right frame 13 and along the direction from the upper frame 12 to the lower frame 14, making the connection point strength far exceed that of directly connecting the left frame 11, upper frame 12, right frame 13, and lower frame 14 with horizontal and vertical bolts. Third, the assembly or disassembly of the door frame 1 can be completed by simply tightening or loosening a few horizontal and vertical bolts, greatly facilitating transportation, relocation, and storage. Fourth, the side plate threaded hole 1323b and the transverse cavity threaded hole 1212 are respectively located behind the left frame 11, the right frame 13, the upper frame 12 and the lower frame 14, which will not drill holes on the front of the door frame 1, thus protecting the integrity and aesthetics of the door frame 1, and also preventing the main load-bearing surface of the door frame 1 from being damaged and reducing its strength.

[0097] Example 2: This example provides a cabinet, including a cabinet body and a door panel connected to the cabinet body. The door panel is the aforementioned door panel with deformation correction function. This example provides a cabinet whose door panel structure is completely identical to that of the door panel with deformation correction function. Correspondingly, the achieved technical effect is also the same as in Example 1. Therefore, this example will not elaborate on its structure and technical effects.
