[0034] As shown in the drawings, the utility model provides a door leaf structure, the door leaf structure includes door frame beam 100, door frame beam 100 is used to support door leaf structure and forms the outline of door leaf structure. Specifically, define the door frame beam 100 as vertical beam along the height direction of door leaf structure extends, and the horizontal beam along the width direction of door leaf structure extends. Door leaf structure is usually provided with two vertical beams and two horizontal beams, and the two horizontal beams are connected between the two vertical beams or the two vertical beams are connected between the two horizontal beams to form a rectangular frame.

[0035] Door frame beam 100 has two support plates 101 relatively distributed along the thickness direction of door leaf structure, and the extension direction of support plate 101 is the width direction of door leaf structure. Both first end 101a and second end 101b are in the extension direction of support plate 101. Two first ends 101a and two second ends 101b are opposite along the width direction. The door leaf structure further includes a type of plate 103 and a type of plate 104, the type of plate 103 is used to abut with two first ends 101a, and the type of plate 104 is used to abut with two second ends 101b to cover the side of door leaf structure, two first ends 101a are aligned, and two second ends 101b are staggered in the extension direction thereof. Wherein, alignment refers to that two first ends 101a are located in the same plane, and staggered refers to that one second end 101b exceeds the other second end 101b in the extension direction of support plate 101, that is, the width direction of door leaf structure. In the installation process, first end 101a or second end 101b is arranged outwardly as the side of door leaf structure.

[0036] Specifically, the type of plate 103 and the type of plate 104 both include plate body, and the plate body is used to cover the end of the corresponding side of door frame beam 100. Wherein, the plate body of the type of plate 103 is a straight face wall, and the plate body of the type of plate 104 is a z-shaped structure. Thus, the position of the avoiding space can be set according to the opening direction of the door leaf.

[0037] In a specific implementation, the type of plate 104 has a concave avoiding groove 104-1, and the avoiding groove 104-1 is used to adapt to the door stop. The avoiding groove 104-1 defines an avoiding space therein, and the size of the avoiding groove 104-1 of the type of plate 104 can be adjusted to adapt to different avoiding space requirements. In the case that the size of the avoiding groove 104-1 remains unchanged, the installation mode of the door frame beam 100 can be adjusted to adapt to the requirements of different opening directions of the door leaf structure.

[0038] When the second end 101b is positioned outwards as a side of the door leaf structure, the body of the second-class plate 104 has a first plate segment, a second plate segment, and a third plate segment. The first and third plate segments extend along the thickness direction and abut against the corresponding second end 101b. The second plate segment connects the first and third plate segments. The outer sides of the second and third plate segments are recessed relative to the first plate segment to form a clearance groove 104-1, which is adapted to fit the door stop. If the clearance groove 104-1 is not required, the installation position of the door frame beam 100 can be adjusted so that the first end 101a faces outwards as a side of the door leaf structure. Here, "inner" and "outer" are defined with reference to the door leaf structure. In the width direction of the door leaf structure, the side pointing towards the center of the door leaf structure is considered inner, and vice versa.

[0039] To provide support for the two support plates 101, at least one connecting plate 102 is connected between the two support plates 101, and the connecting plate 102 extends along the thickness direction. The connecting plate 102 is arranged perpendicular to the support plate 101 and is welded and fixed to the support plate 101.

[0040] By adopting the technical solution of this application, the second ends 101b of the two support plates 101 of the door frame beam 100 are staggered in their extension direction, and the second type plate 104 is used to abut against the second ends 101b, thereby forming a clearance space; at the same time, the first ends 101a are aligned in their extension direction, and the first type plate 103 abuts against the first ends 101a, so that by changing the installation direction of the door frame beam 100, the clearance space can be formed in any direction of the door leaf structure. This allows the structure of the door frame beam 100 to be frequently changed according to the different opening directions of the door leaf, greatly reducing production costs, improving installation efficiency, and enhancing the versatility of the product.

[0041] In the example shown, the door frame beam 100 includes two opposing connecting plates 102 along the extending direction of the support plate 101. The two adjacent connecting plates 102 and a portion of the support plate 101 form a support cavity 106. The support cavity 106 can be rectangular or square, etc. By providing the support cavity 106, the load-bearing capacity of the door frame beam 100 is improved, thus enhancing its structural strength.

[0042] The assembly method of the door frame beam 100 of this application will be described in detail below.

[0043] In the technical solution of this application, the vertical beam and the horizontal beam are assembled at a 90° angle; or, the vertical beam and the horizontal beam are assembled at a 45° angle. The door structure of this application can adapt to both assembly methods, making the assembly method more flexible and further improving its adaptability.

[0044] 90° assembly method

[0045] In one specific embodiment, a first-type connection structure 107 and a second-type connection structure 108 are located within a support cavity 106. The first-type connection structure 107 forms a first connection cavity 107a, and the second-type connection structure 108 forms a second connection cavity 108a. The first-type connection structure 107 is a threaded hole portion adapted to fit a screw, and the first connection cavity 107a is used to insert and accommodate the screw. The second-type connection structure 108 is a corner bracket insertion hole portion adapted to fit a corner bracket, and the second connection cavity 108a is used to insert and accommodate the corner bracket.

[0046] The first connecting cavity 107a is located on the connecting plate 102, and the second connecting cavity 108a is located on the support plate 101. When the vertical beam and the horizontal beam are assembled at 90°, the two first connecting cavities 107a and the two second connecting cavities 108a are centrally symmetrically distributed. Here, central symmetry means that they are symmetrical along the center of the support cavity 106.

[0047] In the example shown, both first connecting cavities 107a are located on the outer side of the connecting plate 102, that is, on the side further away from the centerline of the connecting plate 102. The centerline of the connecting plate 102 extends along the width direction of the door structure and passes through the midpoint of the connecting plate 102 in the thickness direction of the door structure. The two second connecting cavities 108a are located at the junction of the connecting plate 102 and the support plate 101.

[0048] In the actual assembly process, the crossbeam is vertically pressed against the end of the vertical beam, or the vertical beam is positioned outside the crossbeam and pressed against the end of the crossbeam. Then, a screw passes through the first connecting cavity 107a of the crossbeam and vertical beam and is threadedly connected to a type-one connecting structure 107. Simultaneously, an angle bracket passes through the second connecting cavity 108a of the crossbeam and vertical beam and connects to a type-two connecting structure 108. This further increases the variety of connection methods in the 90° assembly scheme, further enhancing adaptability.

[0049] 45° assembly method

[0050] In this configuration, only a second type of connection structure 108 located within the support cavity 106 is provided, which forms a second connection cavity 108a. The second type of connection structure 108 can be adapted to an L-shaped bracket to allow the vertical beam and the horizontal beam to be assembled.

[0051] The second connecting cavity 108a is located on the support plate 101; when the vertical beam and the horizontal beam are assembled at a 45° angle, the second connecting cavities 108a are relatively distributed along the width direction of the door structure. That is, the two second connecting cavities 108a are symmetrically arranged along the centerline of the connecting plate 102. Thus, when assembled at a 45° angle, the connection between the horizontal beam and the vertical beam can be achieved.

[0052] The following is a detailed explanation of the installation method of the door panel 109 in the door structure.

[0053] The door structure also includes a door panel 109, which covers the door beam frame to form the external shape of the door structure.

[0054] Specifically, both ends of the first-type plate 103 and the second-type plate 104 extend beyond the door frame beam 100 along the thickness direction, thereby reserving space for the installation of the door panel 109 of the door leaf structure. Specifically, the door panel 109 has two first panel walls opposite each other along the width direction of the door leaf structure and two second panel walls opposite each other along the thickness direction of the door leaf structure. The first panel walls abut against the portion of the first-type plate 103 or the second-type plate 104 extending beyond the door frame beam on the corresponding side in the width direction, and the second panel walls press against the outer wall of the support plate 101 in the width direction, thereby supporting the door panel 109.

[0055] The end of the first type of board 103 or the second type of board 104 forms a flange 105 to press against a part of the second panel wall, thereby forming an edge of the door panel 109. At this time, the flange 105 extends in a straight line; or it can extend slightly beyond the door panel 109 in the thickness direction to perform a puttying operation on the door panel 109. At this time, the flange 105 has a barbed structure to reserve space for filling the putty.

[0056] The size of the first-class board 103 or the second-class board 104 is the same as that of the corresponding side support board 101, thereby enabling it to adapt to door panel 109 of the same thickness, thus further improving the adaptability of the door structure.

[0057] The following provides a further explanation of how the first-class plate 103 and the second-class plate 104 are connected to the support plate 101.

[0058] In the above embodiments, both type I plate 103 and type II plate 104 include a plate body and two connecting beams opposite each other along the thickness direction; the connecting beams are inserted into the inner side of the two support plates 101 and stop against the inner sidewall of the support plate 101 in the extension direction of the support plate 101.

[0059] In this way, the first type of plate 103 and the second type of plate 104 are inserted into the support plate 101, and this connection method facilitates the processing of the door body.

[0060] In another embodiment, the inner sidewalls of the first end 101a and the second end 101b of the two support plates 101 are provided with a serrated structure; the outer sidewalls of the connecting beam are also provided with a serrated structure. This increases the connection strength between the first type plate 103 and the second type plate 104 in the extension direction of the support plate 101.

[0061] In the aforementioned embodiments, the door frame of the door leaf structure is made of aluminum alloy, and the first-class panel 103 and the second-class panel 104 are also made of aluminum alloy. A graphite homogeneous plate is filled inside the door frame beam 100 to further support the door leaf structure, and the door leaf panel 109 is made of high-density door skin. The aluminum alloy door frame, the first-class panel 103, and the second-class panel 104, due to their material properties and cavity shape, provide a certain degree of anti-deformation for tall doors. Furthermore, the sound insulation coefficient of the graphite homogeneous plate is basically the same as that of traditional door core panels (bridge-hole mechanical panels), and superior to common aluminum honeycomb panels. Therefore, the sound insulation effect of this product is higher than that of existing similar products, providing users with a quieter and more comfortable home life.

[0062] Compared with existing door leaf structures, the technical solution of this application has the following advantages:

[0063] First, the door frame beam 100 in this application has a high degree of adaptability. In the production of door leaf structures, manufacturers can choose door frame beams 100 that are compatible with their respective production stages for assembly. They can freely choose 90° or 45° assembly according to the different production stages of each factory, and can use the same corner bracket for adaptation, thereby further reducing the production costs of manufacturers;

[0064] Secondly, as an optional method, if the door panel 109 is edge-wrapped, a 9 mm thick panel can be used; if it is puttyed, an 8 mm thick door panel 109 can be used. This allows it to cooperate with the door frame, making it sturdy and durable.

[0065] Third, the door leaf structure in this application improves sound insulation to a certain extent. The aluminum alloy material used for the door beam frame also makes the door leaf structure more stable and less prone to deformation, thus meeting customers' requirements for a user-friendly and durable door.

[0066] Fourth, by adopting the technical solution of this application, the second ends 101b of the two support plates 101 of the door frame beam 100 are staggered in their extension direction, and a secondary plate 104 is used to abut against the second ends 101b, thereby forming a clearance space. Simultaneously, the first ends 101a are aligned in their extension direction, and a secondary plate 103 abuts against the first ends 101a. This allows for the creation of clearance space in any direction of the door leaf structure by changing the installation direction of the door frame beam 100. This enables frequent modifications to the structure of the door frame beam 100 according to different opening directions of the door leaf, significantly reducing production costs, improving installation efficiency, and enhancing product versatility. A single door leaf structure can be used in different opening directions, and double doors, mother-daughter doors, etc., can be made simultaneously.

[0067] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
