These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this invention, first information may also be referred to as second information, and similarly, second information may also be referred to as first information.

[0029] In existing technologies, traditional framed doors only support a four-sided frame structure, requiring additional surface-mounted handles and making it impossible to achieve an integrated door panel design. This design limits the product's aesthetics and practicality, failing to meet users' demands for minimalist, high-end door panels. In home settings such as kitchens or wardrobes, external handles not only increase installation steps but also detract from the overall visual appeal of the door panel and pose a risk of bumps and knocks.

[0030] To address these issues, designers noticed that the structural redundancy in traditional framed doors led to the separation of functional modules, prompting them to consider how to achieve component integration through structural reconstruction. After analyzing the stress points and grip requirements of the door panel, they discovered a potential combination between horizontal lines and the handle function. They then attempted to integrate the core panel 1 with the gripping part. Through exploration of modular assembly methods, they ultimately developed an innovative solution that uses groove fitting to create a built-in handle.

[0031] Please see Figures 1 to 6 This utility model proposes a frame-shaped door panel including a core board 1, a horizontal mounting member 2 located on the side end face of the core board 1, and plug-in members 3 located at both ends of the horizontal mounting member 2. The side end face of the core board 1 is provided with a longitudinally penetrating groove structure 10. The horizontal mounting member 2 and the plug-in members 3 are fitted and connected to the core board 1 through the groove structure 10. The horizontal mounting member 2 and the groove structure 10 form a handle part that can be gripped by fingers.

[0032] The core board 1 refers to the board material that serves as the main supporting structure. It can be hinged and installed on furniture such as wardrobe doors, cabinet doors, and drawer doors. The core board 1 can be made of engineered wood, fiberboard, or solid wood. The core board 1 is generally a rectangular board with six sides. The front side is the exterior surface of the door panel, the rear side is hidden inside, for example, the wardrobe, and the four side sides are the top side, bottom side, left side, and right side. The groove structure 10 of the core board 1 can be formed on one of the four side sides, and the handle design can be achieved through horizontal or vertical installation. The designed vertical through groove provides assembly space for the horizontal component 2 and the plug-in component 3. The horizontal component 2 is a linear component, which can be made of aluminum alloy profile, aluminum-plastic composite, wood-plastic composite, or the same material as the core board 1. It forms an extension of the core board 1 by fitting into the groove structure 10, and together with the core board 1, it constitutes the handle part. The connector 3 is a linear component that connects the ends of the horizontal assembly 2, used to close the horizontal assembly 2 and the core plate 1. The connector 3 also serves to reinforce and fix the horizontal assembly 2. The connector 3 can be made of the same material as the core plate 1 or the horizontal assembly 2. The groove structure 10 refers to the continuous groove on the side end face of the core plate 1, which can be formed by milling to achieve the fitting assembly of the horizontal assembly 2 and the connector 3.

[0033] Specifically, the groove structure 10 on the side end face of the core board 1 extends in one direction, for example, vertically when installed vertically and horizontally when installed horizontally. The horizontal component 2 is positioned and assembled with the core board 1 by embedding into the groove. First, adhesive is applied to the groove structure 10 to initially fix the horizontal component 2 and the connector 3, and then it is cured by heating. Finally, it is reinforced and fixed by installing nails on the rear end face of the core board 1. The horizontal component 2 and the side wall of the groove structure 10 form a handle that allows fingers to be inserted, so that the frame-shaped door panel also has a gripping function. The connectors 3 are distributed at both ends of the horizontal component 2 and are longitudinally connected by fitting into the groove to form a stable frame structure. This integrated design eliminates the need for an external handle for the door drawer, and the door panel surface remains flat.

[0034] Compared to existing technologies, traditional framed doors require four-sided frame splicing, resulting in prominent frame lines on all four sides of the core panel 1, leading to poor aesthetics. Furthermore, traditional framed doors require independent handles, which protrude from the front of the core panel 1, further reducing its overall appearance. While methods that integrate handle components by carving grooves into the surface of the core panel 1 achieve a seamless design, they also create visual discontinuity and are unsuitable for the high-end requirements of wardrobes. This solution achieves three-sided frame splicing through a groove structure 10 on one side of the core panel 1, providing the handle function while reducing the number of frame lines, simplifying the assembly process and improving the overall appearance.

[0035] Through the above technical solution, this utility model achieves structural integration of the door drawer frame and the handle, eliminating the visual discontinuity caused by external handles and maintaining a complete flat surface on the door panel. The interlocking assembly method improves structural stability, avoids the risk of loosening associated with traditional surface-mounted handles, and meets the dual needs of modern homes for a minimalist appearance and integrated functionality.

[0036] The current frame structure can be either right-angled or beveled. The difference between the two lies in the structural strength and appearance. Based on people's pursuit of beauty, this utility model further proposes that the insert 3 and the horizontal mounting 2 are provided with a matching beveled surface.

[0037] The splicing bevel refers to the inclined mating structure formed on the contact surface between the insert 3 and the horizontal assembly 2. This can be achieved using a planar bevel or an arc-shaped bevel, with the bevel direction forming a non-perpendicular angle with the assembly path. The mating refers to the complementary contact form between the bevels of the insert 3 and the horizontal assembly 2. This can be achieved using equal-angle matching or progressive-angle matching, ensuring a continuous contact surface during assembly.

[0038] Specifically, when the connector 3 and the horizontal component 2 are assembled through beveled contact, the inclined contact surface provides directional guidance, forcing the connector 3 to move along a predetermined path until it is fully engaged, thereby eliminating lateral offset errors during assembly. Simultaneously, the beveled fit causes the seam line to extend along the inclined direction. Compared to traditional right-angle splicing, the seam is visually decomposed into a natural transition of the beveled edge, thus concealing the actual seam location. In terms of structural strength, the beveled contact increases the effective connection area compared to right-angle contact, increasing the structural strength of the horizontal component 2 and the connector 3 after adhesive bonding.

[0039] This utility model further proposes a technical solution to set the splicing slope of the connector 3 and the horizontal mounting 2 to 45°.

[0040] The 45° bevel angle refers to the geometric angle formed by the contact surfaces of the two connecting parts, which can be achieved through mold forming or CNC machining. This angle value is chosen because it meets the requirement of forming right-angle structures in woodworking splicing processes, satisfying the requirement of standardized processing benchmarks while also providing mechanical constraints through bevel interlocking.

[0041] Traditional four-sided frame structures require a horizontal component 2 on each of the four side faces of the core board 1. These horizontal components 2 are joined in pairs using a 45° bevel. Although this bevel is machined, machining errors are unavoidable. Since both ends of the horizontal components 2 need to be seamlessly joined, any bevel error in any one of the horizontal components 2 will result in seam deviations in the overall four-sided frame, leading to product defects. In such cases, only material replacement or surface repair is an option, undoubtedly increasing the company's costs.

[0042] This invention only involves three-sided framing on one side of the core board 1. Each core board 1 requires one horizontal mounting piece 2, which is then joined with two connectors 3. As shown in the accompanying drawings, both ends of the horizontal mounting piece 2 have beveled surfaces, while the connectors 3 have a beveled surface on one end. Compared to existing technologies, this undoubtedly reduces the number of beveled surfaces required for framing, lowers the precision requirements for line splicing, reduces the complexity of the traditional 45° bevel cutting process, avoids alignment deviations caused by misalignment, improves production efficiency, and reduces the defect rate. Simultaneously, it reduces the need for high-precision bevel cutting, making the processing simpler, reducing processing difficulty, and thus lowering production costs.

[0043] This utility model further proposes a groove structure 10 including a side baffle 10a and a side baffle 10b extending outward from the side end of the core plate 1 and parallel to each other. A horizontal component 2 and a plug-in component 3 are both embedded between the side baffle 10a and the side baffle 10b. The horizontal component 2 is provided with a first notch 20 for engaging the side baffle 10a, and the plug-in component 3 is provided with a second notch 30 for engaging the side baffle 10a. The side of the horizontal component 2 facing the side baffle 10b is provided with a longitudinally penetrating recessed structure, and the recessed structure and the side baffle 10b form a handle.

[0044] The side baffle 10a and side baffle 10b are both strip-shaped structures extending longitudinally along the edge of the core plate 1. The side baffle 10a and side baffle 10b are formed by milling the core plate 1, that is, the side baffle 10a, side baffle 10b and the main structure of the core plate 1 are integrally formed. The side baffle 10b and side baffle 10a together form a double-sided support structure, and the height of the side baffle 10a is lower than the height of the side baffle 10b. The horizontal component 2 and the plug-in component 3 are embedded between the side baffle 10b and the side baffle 10a. The first notch 20 and the second notch 30 are recessed structures on the sides of the horizontal component 2 and the plug-in component 3 that match the contour of the side baffle 10a. Specifically, they can be formed by milling and are used to achieve longitudinal snap-fit ​​positioning. The recessed structure refers to the groove that is recessed inward along the length of the surface of the horizontal component 2. It forms an accommodating space between itself and the side baffle 10b to conform to the gripping shape of the fingers, so that people can hold the side baffle 10b to open and close the frame door.

[0045] Specifically, the side baffle 10a and the side baffle 10b form a fitting cavity through parallel extension, allowing the horizontal component 2 to achieve self-positioning under the constraint of both sides during assembly. The interlocking action of the first notch 20 and the second notch 30 prevents relative displacement between the horizontal component 2 and the core plate 1 during the pulling process, ensuring the tightness of the joints at the edge of the door panel and improving the stability during assembly. The recessed structure extends longitudinally through the surface of the horizontal component 2, forming a clamping gap with a width of 20-25 mm between it and the side baffle 10b. The depth of this gap is gradient-transitioned through the arc-shaped bottom surface of the recessed structure, maintaining the flatness of the outer surface while meeting the gripping requirements. The fit between the recessed structure and the side baffle 10b eliminates the need for additional handle components, and is completely hidden in the frame structure when the door panel is closed.

[0046] Compared to existing technologies, traditional framed doors require protruding individual handles on the door panel surface, resulting in an uneven appearance and increased assembly steps. This solution integrates the handle function into the main structure of the horizontal component 2, achieving a concealed design through the recessed structure and its cooperation with the side baffle 10b, eliminating the impact of exposed components on the overall integrity of the door panel. Compared to the point-loaded structure of individual handles, the side baffle 10b uses the core panel 1 as the load-bearing point; its longitudinally continuous structure disperses gripping stress, avoiding the risk of localized deformation.

[0047] Through the above technical solution, this utility model achieves functional integration of the door panel handle structure and the frame assembly, eliminating the additional assembly steps required by traditional surface-mounted handles. The recessed structure maintains the flatness of the door panel's outer surface while providing an ergonomic grip depth, and the interlocking design of the side strip 10a and the notch enhances the structural strength between components. This solution allows the door panel to present a completely flat surface when closed, meeting the technical requirements of high-end home furnishing products for a minimalist appearance.

[0048] This utility model further proposes that the corner of the recessed structure near the side baffle 10b is rounded, and the corner of the recessed structure away from the side baffle 10b is inclined.

[0049] In one feasible approach, the horizontal component 2 can be assembled from multiple plates, such as a horizontal flat plate, a plate with a triangular prism structure, and a rectangular plate, with a semi-cylindrical groove milled on one side of the rectangular plate. Simultaneously, the tilt angle is equal to the bevel angle between the horizontal component 2 and the insert; that is, when the bevel angle is 45°, the chamfer is also 45°, improving the appearance of the beveled edge assembly.

[0050] This invention further proposes a 45° inclination angle, where the corner of the recessed structure away from the side baffle 10b extends at a 45° inclination angle to the surface of the horizontal component 2. This angle, combined with the 45° angle of the inclined surface of the connector 3, creates a synergistic processing effect. When a finger touches the recessed area, the inclination angle guides the fingertip to move naturally down the inclined surface, while the rounded corner eliminates hard contact with the palm, forming a continuous gripping surface. Simultaneously, the 45° standard angle allows the horizontal component 2, connector 3, and core plate 1 to use the same processing reference surface, reducing mold parting errors and ensuring that the fitting gap is controlled within a 0.5 mm tolerance range.

[0051] This utility model further proposes that the connector 3 is a triangular prism, and the cross-section of the triangular prism is an isosceles right triangle.

[0052] The triangular prism refers to a prism-shaped structure enclosed by three planes, whose geometric symmetry forms a natural positioning reference. The cross-section is an isosceles right triangle, meaning the cross-section perpendicular to the prism's extension direction has two equal-length right-angled sides. These two right-angled sides of the triangular prism form surface contact with the vertical mounting surface of the horizontal component 2, while the hypotenuse naturally forms a 45° splicing slope. During assembly, the geometric symmetry of the isosceles right-angled triangle allows the connector 3 to match the horizontal component 2 without distinguishing the installation direction; the sharp corner of the right angle automatically embeds into the gap of the mounting reference surface 21 of the horizontal component 2. The three planes of the triangular prism simultaneously contact the horizontal component 2, constraining the longitudinal and lateral displacement of the connector 3 through the principle of triangle stability. The continuous splicing surface formed by the hypotenuse covers the gap area present in traditional right-angle splicing.

[0053] This utility model further proposes that the two corners of the connector fitting to the horizontal mounting part 2 have positioning reference surfaces 31, the two positioning reference surfaces 31 are perpendicular to each other, and the horizontal mounting part 2 is provided with an installation reference surface 21 that cooperates with the positioning reference surfaces 31.

[0054] The positioning reference surface 31 refers to the plane at the corner of the triangular prism connector 3 used for alignment with the horizontal mounting component 2. This can be achieved by milling to form mutually perpendicular planes, using orthogonal positioning constraints to solve assembly misalignment problems. The mounting reference surface 21 refers to the plane on the horizontal mounting component 2 that mates with the positioning reference surface 31. This can be achieved by milling a plane that matches the positioning reference surface 31, enhancing connection stability through physical limiting relationships.

[0055] Specifically, after setting mutually perpendicular positioning reference surfaces 31 on the two corners of the connector 3, the positioning reference surfaces 31 can be directly aligned with the mounting reference surface 21 of the horizontal component 2 during assembly, achieving bidirectional positioning in both horizontal and vertical directions. Due to the vertical characteristics of the positioning reference surface 31, the connector 3 and the horizontal component 2 can be precisely aligned without additional adjustments. Combined with the structural feature of the triangular prism having an isosceles right triangle cross-section, the spatial matching relationship between the positioning reference surface 31 and the mounting reference surface 21 of the horizontal component 2 further simplifies the assembly steps, supports the efficient assembly of the integrated door panel structure, solves the assembly difficulties caused by inaccurate positioning of the connector 3 and the horizontal component 2, achieves rapid assembly through bidirectional positioning constraints, and enhances connection stability through surface contact, enabling the overall door drawer structure to meet the precision and strength requirements of integrated design.

[0056] This utility model further proposes to laminate wood veneer onto the surface of the core board 1. In the wood veneer lamination process, the hot pressing temperature is controlled at 90-120℃, the pressure range is 0.5-1.2 MPa, and the adhesive used is a polyurethane adhesive.

[0057] This utility model further proposes that the side ends of the core board 1, the horizontal component 2, and the connector 3 are covered with wood veneer edge banding. By covering the splicing parts of the core board 1, the horizontal component 2, and the connector 3 with wood veneer edge banding, the door drawer presents a continuous wood veneer surface.

[0058] The assembly process of the frame-shaped door panel provided by this utility model is as follows:

[0059] 1. Core board 1 cutting and grooving: Cut the core board 1 and grooving is performed on any one of the four cutting surfaces.

[0060] 2. Processing horizontal component 2 and connector 3: Cut and mill the horizontal component 2 and the two connectors 3.

[0061] 3. Overall assembly: Apply glue evenly to the groove structure 10 of the core board 1, and assemble the horizontal assembly 2 and the plug-in assembly 3.

[0062] 4. Shaping process: Use external clamping and fixing devices to fix the assembly in step 3 from four directions: top, bottom, left and right. At the same time, use nails to further reinforce the core board 1 on the reverse side.

[0063] 5. Semi-finished product processing: Place the semi-finished product from step 4 in a dry environment and allow it to dry completely. Then, perform a fixed-thickness sanding process and finely trim the four sides.

[0064] 6. Finished product: Wood veneer is pressed onto both sides of the entire framed door panel, followed by three-sided edge sealing, and finally painting to produce the finished product.
