Description

Technical Field

[0001] This application relates to the field of door technology, and more specifically, to a door leaf and door structure. Background Technology

[0002] Door panels are typically made using an edge-sealing process, and the intersection of the side and front of the door panel is usually at a right angle, which reduces the aesthetics of the door panel and makes it prone to scratches and other safety risks.

[0003] Traditional door panels typically have adhesive applied to the sides and then bonded to the two front panels. A notch is created at the intersection of the side and front panels, and this notch is filled with adhesive to create a rounded corner, preventing scratches and other safety risks. However, during use, the limited bonding area on the side panels makes them prone to cracking.

[0004] In addition, using colloid to achieve the rounded chamfer results in a large arc angle and uneven chamfers, affecting the aesthetics of the door.

[0005] Therefore, how to reduce the risk of cracking on the side of the door leaf has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of this application is to provide a door leaf to reduce the risk of side cracking of the door leaf.

[0007] Another objective of this application is to provide a door structure having the aforementioned door leaf.

[0008] To achieve the above objectives, this application provides the following technical solution:

[0009] A door leaf, comprising:

[0010] The panel consists of two panels, with a support member provided between the two panels;

[0011] A side panel, which extends from one of the two panels and bends toward the other of the two panels to make the side panel and the support member fit together in a concave-convex connection, and the side panel and the support member are bonded and fixed together by an adhesive.

[0012] Optionally, in the above-mentioned door panel, the panel includes a first panel and a second panel, the side panel is formed by extending from the first panel, and a bending portion is formed between the side panel and the first panel so that the side panel bends toward the second panel.

[0013] Optionally, in the above-mentioned door leaf, the thickness of the bent portion is 0.20mm to 0.30mm; and / or,

[0014] The width of the bent portion is 3.5mm to 4mm; and / or,

[0015] The bending radius of the side panel toward the second panel is 1.3mm to 1.7mm.

[0016] Optionally, in the above-mentioned door leaf, the width of the first panel is 35mm to 45mm greater than the width of the second panel to form the side panel.

[0017] Optionally, in the above-mentioned door leaf, a first protrusion is provided on the side panel, and a first groove that mates with the first protrusion is provided on the support member; or,

[0018] The side plate is provided with a second groove, and the support member is provided with a second protrusion that cooperates with the second groove.

[0019] Optionally, in the aforementioned door leaf, the thickness of the first protrusion is 3.0 mm to 4.0 mm; and / or,

[0020] The width of the first protrusion is 20mm to 30mm; and / or,

[0021] The depth of the first groove is 2.05mm to 2.25mm.

[0022] Optionally, in the above-mentioned door leaf, a first platform and a second platform are formed on both sides of the first protrusion, the thickness of the first platform and the second platform are both less than the thickness of the first protrusion, the second platform is disposed on the side away from the first panel, and the thickness of the second platform is 1.75mm to 2mm.

[0023] Optionally, in the above-mentioned door leaf, the first platform is provided with a rounded chamfer at one end near the first panel, and the rounded chamfer, the bent portion and the end face of the first panel surround to form a potting groove for potting adhesive.

[0024] Optionally, in the above-mentioned door leaf, the panel is one of MDF, particleboard, plywood, solid wood board, or FOSB board; and / or,

[0027] A door structure comprising a door leaf as described in any of the preceding claims.

[0028] The door leaf provided in this application has a support member between two panels. One of the two panels extends to form a side panel, which is bent towards the other panel to create a convex-concave fit with the support member. The side panel and support member are then bonded together with an adhesive.

Obviously, the drawings described below are only embodiments of this application. For those skilled in the art, other drawings can be obtained based on the provided drawings without creative effort.

[0033] Wherein, 100 is the panel, 101 is the support member, 1011 is the first groove, 102 is the first panel, 103 is the second panel, and 104 is the adhesive;

[0035] The core of this application is to provide a door leaf that reduces the risk of side cracking.

[0036] Another core aspect of this application is to provide a door structure having the aforementioned door leaf.

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] Traditional door panels typically have adhesive applied to the sides and then bonded to the two front panels. A notch is created at the intersection of the side and front panels, and this notch is filled with adhesive to create a rounded corner, preventing scratches and other safety risks. However, during use, the limited bonding area on the side panels makes them prone to cracking.

[0039] In addition, using colloid to achieve the rounded chamfer results in a large arc angle and uneven chamfers, affecting the aesthetics of the door.

[0040] Therefore, such as Figure 1 As shown in the figure, this application discloses a door leaf, including a front panel 100 and a side panel 200. By using a concave-convex fit mechanical connection between the side panel 200 and the support member 101, and simultaneously using an adhesive 104 for connection and fixation, the stability and reliability of the connection of the side panel 200 can be improved. Furthermore, the concave-convex fit between the side panel 200 and the support member 101 can increase the bonding area and improve the connection strength of the side panel 200, thereby effectively reducing the risk of cracking on the side of the door leaf.

[0041] The following will combine Figure 1 and Figure 2 The explanation and illustration will be based on a 45mm thick magnetic silent door leaf.

[0042] Among them, such as Figure 1 and Figure 2 As shown, there are two panels 100, and a support member 101 is provided between the two panels 100. At least two support members 101 can be used, that is, there can be two, three or more support members 101. At least two support members 101 are respectively provided on both sides of the panel 100 along the width direction of the panel 100, so as to connect and fix the two panels 100 through each support member 101.

[0043] For example, panel 100 may be made of MDF, and support member 101 may be made of wood. Support member 101 and panel 100 may be fixed together by means of adhesive, bolts, or other methods. Of course, panel 100 may also be made of particleboard, plywood, solid wood board, or FOSB (Fine Oriented Surface Board), which is not limited herein.

[0044] like Figure 2 As shown, the side panel 200 can be formed by extending one of the two panels 100 and bending towards the other of the two panels 100 so that the side panel 200 and the support member 101 are connected by a concave-convex fit. The side panel 200 and the support member 101 can be bonded and fixed together by an adhesive 104. Thus, by using a concave-convex fit mechanical connection between the side panel 200 and the support member 101, and simultaneously using an adhesive 104 for connection and fixation, the stability and reliability of the connection of the side panel 200 can be improved. Furthermore, the concave-convex fit between the side panel 200 and the support member 101 can increase the bonding area and improve the connection strength of the side panel 200, thereby effectively reducing the risk of cracking on the side of the door leaf.

[0045] For example, adhesive 104 can be a hot melt adhesive, thereby achieving the connection and fixation of the side plate 200 by applying hot melt adhesive to the connection surface between the side plate 200 and the support member 101, thus improving the stability and reliability of the connection of the side plate 200. Of course, adhesive 104 can also be either white glue or PUR glue (Polyurethane Reactive, moisture-curing reactive polyurethane hot melt adhesive), which is not limited here.

[0046] For ease of understanding, such as Figure 1 and Figure 2 As shown, the two panels 100 are defined as the first panel 102 and the second panel 103, respectively. The first panel 102 is the front of the door leaf, that is, the side of the door leaf facing the outside, and the second panel 103 is the back of the door leaf, that is, the side of the door leaf facing the inside. The side panel 200 extends from the first panel 102, and a bending portion 201 is formed between the side panel 200 and the first panel 102, so that the side panel 200 bends toward the second panel 103.

[0047] For example, such as Figure 2 As shown, the width of the first panel 102 is 35mm to 45mm greater than the width of the second panel 103, so that a side panel 200 is formed, i.e., the width of the side panel 200 is 35mm to 45mm. Meanwhile, the thickness of the bending portion 201 can be 0.20mm to 0.30mm, and the width of the bending portion 201 can be 3.5mm to 4mm to ensure the strength of the bending portion 201, preventing the side panel 200 from breaking during bending, and ensuring that the bending radius of the side panel 200 towards the second panel 103 is 1.3mm to 1.7mm. Preferably, the bending radius of the side panel 200 towards the second panel 103 can be 1.5mm to reduce the bending angle of the side panel 200, improving aesthetics. At the same time, limiting the width of the bending portion 201 ensures the consistency of the bending radius, avoiding uneven bending angles that would affect the aesthetics of the door.

[0048] To achieve a concave-convex fit connection between the side plate 200 and the support member 101, such as Figure 2 As shown, a first protrusion 202 can be provided on the side panel 200, and a first groove 1011 that mates with the first protrusion 202 is provided on the support member 101. This allows the first protrusion 202 to be inserted into the first groove 1011 when the side panel 200 is bent, thereby achieving a mechanical connection between the side panel 200 and the support member 101 through a convex-concave fit. This also increases the bonding area, improves the connection strength of the side panel 200, and effectively reduces the risk of cracking on the side of the door. Alternatively, a second groove can be provided on the side panel 200, and a second protrusion that mates with the second groove can be provided on the support member 101, thereby achieving a convex-concave fit connection between the side panel 200 and the support member 101.

[0049] For example, the thickness of the first protrusion 202 can be 3.0mm to 4.0mm, the width of the first protrusion 202 can be 20mm to 30mm, and the depth of the first groove 1011 can be 2.05mm to 2.25mm. Preferably, the thickness of the first protrusion 202 is 3.5mm, and the width of the first protrusion 202 is 25mm, to ensure the reliability of the insertion between the first protrusion 202 and the first groove 1011, and at the same time to avoid the risk that the strength of the support member 101 will be greatly weakened due to the excessive depth of the first groove 1011.

[0050] like Figure 2 As shown, a first platform 203 and a second platform 204 are formed on both sides of the first protrusion 202, and the thickness of both the first platform 203 and the second platform 204 is less than the thickness of the first protrusion 202. The second platform 204 is located on the side away from the first panel 102, and the thickness of the second platform 204 can be 1.75mm to 2mm. Meanwhile, as... Figure 1 and Figure 2 As shown, a rounded chamfer 2031 is provided at one end of the first platform 203 near the first panel 102, so that the rounded chamfer 2031, the bent portion 201 and the end face of the first panel 102 form a potting groove 205 for potting adhesive 104. Thus, by filling the potting groove 205 with adhesive 104, the connection between the side plate 200 and the support member 101 can be made more firm and reliable. Furthermore, by providing the rounded chamfer 2031 at one end of the first platform 203 near the first panel 102, the contact area with the adhesive 104 can be increased, thereby improving the bonding strength.

[0051] When sealing the door leaf, the door leaf is placed on a bending machine and processed by a flat groove cutter via the equipment conveyor belt to form a first platform 203 and a second platform 204; a first groove 1011 is made on the support member 101 by a vertical cutter; a filling groove 205 is made on the door leaf by a cutter via the equipment conveyor belt; the processed door leaf is transported to the glue application position via the equipment conveyor belt, and adhesive 104 is applied to the filling groove 205 and the first protrusion 202; the second platform 204 is bent by the bending machine press, so that the bending radius of the bent part 2012 can be stabilized at 1.5mm after bending. At the same time, after bending, the second platform 204 is attached to the second panel 103. At this time, the first protrusion 202 is tightly inserted into the first groove 1011, and the gap between the first protrusion 202 and the first groove 1011 is filled by adhesive 104, which improves the stability of the structure.

[0052] To ensure the aesthetics of the door panel, the panel 100 may be provided with a finish, and the finish of the panel 100 may be one of the following: paint finish, UV paint finish, melamine paper, PETG finish or EB finish.

[0053] This application also discloses a door structure, including a door leaf, which is the same as the door leaf disclosed in the above embodiments. Therefore, this door structure has all the technical effects of the above-mentioned door leaf, and will not be repeated here.

Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.
