[0028] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.
[0029] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.
[0030] Combination Figures 1 to 7 As shown, in one embodiment of the present application, a furniture door assembly is proposed, including: a frame 1 and a core board 2, the frame 1 is welded as a whole to form a door frame 3, the core board 2 is installed on the front side of the door frame 3, and is connected to the door frame 3 through an adhesive layer 4, and an edging structure 31 is formed at the outer edge of the door frame 3, and the edging structure 31 surrounds the core board 2.
[0031] Specifically, Figure 1 and Figure 2 As shown, the furniture door assembly in this embodiment includes four frames 1, which can be divided into an upper frame, a lower frame, a left frame and a right frame. For simplicity, only one of the frames is marked in the figure; Figure 3 As shown, the four frames 1 can be enclosed to form a door frame 3 through an integrated welding process, and the outer edges of the four frames 1 are formed with edging. After welding is completed, the four edgings together constitute an edging structure 31 at the outer edge of the door frame 3, and the edging structure 31 is used to surround the core panel 2.
[0032] It can be understood that integrated welding is a welding process that uses thermal equivalence to bond different parts of the same material into one. It can usually be achieved by welding methods such as tungsten inert gas welding and plasma welding, and is suitable for welding and manufacturing of metal materials such as aluminum alloys, stainless steel, and copper. Among them, tungsten inert gas welding is a welding method that uses the arc between the tungsten electrode and the workpiece to melt the metal to form a weld, and argon gas is fed into the welding torch nozzle as a protection; plasma welding is a welding method that uses a compressed arc between the electrode and the workpiece to achieve welding, and the plasma gas that generates the plasma arc can be argon, nitrogen, helium, or a mixture of these gases.
[0033] In some preferred embodiments, each frame 1 in the present application can be processed into a door frame 3 by at least one welding process of tungsten inert gas arc welding and plasma welding.
[0034] It can be seen that compared with the door-type structure assembled by plastic connecting codes and structural adhesive (or screws) in the prior art solution, the furniture door assembly in the present application is not only simple in structure and easy to assemble, but also omits processes such as profile punching and screw framing, simplifies the production and processing process, is more conducive to mass production, and improves production efficiency.
[0035] It should be noted that the furniture door assembly in the embodiment of the present application can meet the user's demand for narrow-frame door types; for example, the visible width range of the front of the door frame 3 is 5-10 mm. In other words, the width range of the front of each frame 1 in the door frame 3 (i.e., the width of the edging structure 31) is 5-10 mm.
[0036] In a preferred embodiment of the present application, Figure 6 As shown, the width of the front side of each frame 1 in the door frame 3 is 8 mm, the width of the back side of each frame 1 is 60 mm, and the thickness of each frame 1 is 20 mm, while the thickness of the core board 2 is 18 mm. Of course, the present application does not limit the shape, size, quantity, and installation method of the frame 1, the core board 2, and the door frame 3.
[0037] In some preferred embodiments, each frame 1 is made of an aluminum profile structure, and is an integrated structure formed by an aluminum profile extrusion process, such as a solid aluminum profile structure. The aluminum profile extrusion process is a processing method in which an aluminum material is heated to a certain temperature and then extruded into profiles of different shapes using pressure; since aluminum profiles have the advantages of light weight, high strength, and corrosion resistance, the frame produced by the aluminum profile extrusion process in this embodiment also has the advantages of light weight, low cost, and strong flexibility.
[0038] Specifically, the four frames 1 in this embodiment can form an integral door frame 3 after cutting, welding, grinding, and surface coloring, thereby achieving a seamless effect of the furniture door assembly and making the product appearance more beautiful. Of course, other processes can also be used to produce and process the frames to achieve a seamless effect after the frames are spliced.
[0039] In some embodiments of the present application, Figure 4 As shown, the core panel 2 includes a core panel body 21 and a core panel connection portion 22 extending from the core panel body 21 to one side of the door frame 3. In the embodiment of the present application, the bonding layer 4 adopts an adhesive. Therefore, the adhesive (such as structural adhesive) can be applied at the contact position between the core panel body 21 and the front of the door frame 3, and the core panel connection portion 22 can be installed in the installation space 32 formed in the middle of the door frame 3, thereby making the installation more convenient and firm.
[0040] In some preferred embodiments, Figure 2 , Figure 6 and Figure 7 As shown, a first limiting portion 11 is provided at the inner edge of each frame 1, and each first limiting portion 11 is provided along the side end of the core board connecting portion 22, that is, the thickness of the first limiting portion 11 is consistent with the thickness of the core board connecting portion 22, and after welding is completed, the first limiting portions 11 can jointly form a first limiting edge to limit the core board body 21. Such a design allows a gap for coating structural adhesive between the door frame 3 and the core board 2, which is more conducive to the fixation of the core board 2.
[0041] In some preferred embodiments, continue to refer to Figure 2 , Figure 6 and Figure 7 As shown, a second limiting portion 12 is also provided at the inner edge of each frame 1, and each second limiting portion 12 is fitted with the back side of the core board connecting portion 22, and after welding is completed, the second limiting portions 12 can jointly form a second limiting edge to limit the core board connecting portion 22, thereby achieving the positioning and stabilization effect of the back side of the core board 2.
[0042] In some embodiments, Figure 7 As shown, a chamfer 33 is provided at the outer edge of the edging structure 31 to make the edge of the door frame 3 smoother and effectively avoid collision damage; at the same time, the core panel 2 is partially arranged in the edging structure 31, so that the front side of the core panel 2 protrudes from the door frame 3, that is, the front side end face of the core panel 2 is suspended outside the door frame 3. Such a design can make the connection between the core panel 2 and the edging structure 31 more natural, further improving the aesthetics of the product.
[0043] Of course, the above content is only an exemplary description, and the present application does not limit the connection method between the core board 2 and the door frame 3.
[0044] In some embodiments of the present application, the core board 2 is any one of a leather-coated core board and a PVC blister core board (PVC, polyvinyl chloride). For example, the leather-coated core board in the present embodiment can be a wooden core board coated with leather material, or an aluminum honeycomb core board coated with leather material, thereby making the product more beautiful in appearance, and having better wear resistance and less prone to cracking. Of course, the present application does not limit the material of the core board 2.
[0045] In another embodiment of the present application, a piece of furniture is provided, including a furniture door assembly as in any one of the above embodiments. Specifically, the furniture in this embodiment includes but is not limited to a cabinet, a storage cabinet or a shower room, etc. Of course, the present application does not limit the type of furniture, the installation method between the furniture and the furniture door assembly, and the number of furniture door assemblies installed on the furniture.
[0046] It can be seen that applying the furniture door assembly in the embodiment of the present application to furniture can not only meet the user's demand for narrow-frame door types, but also make its assembly and maintenance more convenient, and its appearance more beautiful, and can be widely used in various home or office places.
[0047] In summary, the present application proposes a furniture door assembly and furniture, which achieves a seamless effect of a narrow-frame door type by welding four frames into one piece to form a door frame, making the product appearance more beautiful; by forming an edging structure at the outer edge of the door frame and using the edging structure to surround the core board, the core board can be installed on the front side of the door frame and connected to the door frame through an adhesive layer, thereby not only making the structure of the furniture door assembly simple and easy to assemble, but also omitting processes such as punching holes in profiles and screwing frames, which is more conducive to mass production and improves production efficiency.
