Open-close structure for television cabinet and television cabinet

Abstract

The application discloses a hinge structure and a TV cabinet, which comprises a hinge, a first fixing member and a second fixing member. The first fixing member and the second fixing member bear and transfer loads, thereby effectively avoiding that the fixing screw directly bears the main load, solving the problem that the fixing screw is easily deformed plastically and even gradually pulled out due to long-term direct stress in the traditional structure. The hinge is provided with an embedded plate one and an embedded plate two, and the first fixing member and the second fixing member are correspondingly provided with a lock one and a lock two. During assembly, the embedded plate one and the embedded plate two are accurately embedded in the two locks respectively, thereby forming a rigid connection similar to the traditional mortise and tenon structure. The close mechanical interlocking not only ensures the absolute fastening of the connection, but also fundamentally prevents the hinge from being loose or even separated from the two fixing members under long-term vibration or load, thereby greatly enhancing the integrity of the connection node.

Description

Technical Field

[0001] This invention relates to the field of TV cabinet technology, and specifically to an opening and closing structure for a TV cabinet and the TV cabinet itself. Background Technology

[0002] TV cabinets are a common and important piece of functional furniture in living rooms. They not only provide basic storage but also contribute to the overall style and aesthetics of the living room. Traditional installation and placement designs typically involve reserving a dedicated mounting location or recessed space to directly hang or fix the television to the wall. While this ensures stable installation, it also leads to a significant waste of the TV cabinet's storage space, especially in homes with relatively limited living room area and residents with high storage needs.

[0003] To resolve this contradiction, another design approach has emerged: mounting the television directly onto one of the cabinet doors. This method effectively utilizes cabinet space, allowing the television to be hung while still maintaining the cabinet's internal storage function, thus avoiding wasted storage space. However, with the continuous increase in television screen size in recent years, the overall weight of the television has also increased accordingly, placing higher demands on the load-bearing structure of the TV cabinet doors. Currently, most TV cabinets on the market still use traditional hinges or ordinary connection structures for their doors, which are unable to withstand the large loads continuously applied by the television. Especially during prolonged use, the doors are prone to deformation, sagging, or even complete detachment. This structural instability not only affects the functionality of the TV cabinet but also poses a risk of the television accidentally falling, presenting a significant safety hazard. Summary of the Invention

[0004] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, a first aspect of this invention provides an opening and closing structure for a TV cabinet, including a hinge, a first fixing member, and a second fixing member; the hinge includes an upper page and a lower page, the upper page and the lower page being arranged vertically, the upper page including an embedded plate one, and the lower page including an embedded plate two; the first fixing member is fixed to the cabinet door and is provided with a locking slot one; the second fixing member is fixed to the cabinet body and is provided with a locking slot two; the embedded plate one and the locking slot one, and the embedded plate two and the locking slot two, form an interlocking connection.

[0005] According to some embodiments of the present invention, both the upper and lower page sheets include arc-shaped plates, which are used to connect with the first and second embedded plates. The arc-shaped plates are symmetrically provided with two first embedded openings, which are adjacent to the ends of the embedded plates. Both the first and second locking openings include a second embedded opening and an embedded portion. The end of the first or second embedded plate is embedded in the second embedded opening, and the embedded portion is embedded in the first embedded opening.

[0006] According to some embodiments of the present invention, the bending direction of the upper arc-shaped plate is opposite to that of the lower arc-shaped plate, forming an intersecting shape.

[0007] According to some embodiments of the present invention, the hinge further includes a shaft, and the leaf blades are provided with sleeves along the longitudinal axis. The shaft is vertically inserted into the two sleeves, so that the two blades are connected in series and the two blades rotate about the shaft.

[0008] According to some embodiments of the present invention, the second fastener includes a first plate, a second plate, and a third plate, wherein the first plate and the second plate are perpendicular to each other, the second plate and the third plate are perpendicular to each other, the first plate is located behind the second plate, and the third plate is located in front of the second plate. The first panel is fixedly connected to the cabinet, and the third panel is provided with the second lock slot.

[0009] According to some embodiments of the present invention, a reinforcing plate is snapped between plate one and plate two, so that the combination of plate one, plate two and the reinforcing plate forms a triangle.

[0010] A second aspect of the present invention provides a TV cabinet, including a cabinet door and a cabinet body. A TV is fixedly installed on the cabinet door, and an opening and closing structure is provided between the cabinet body and the cabinet door. The hinge adopts the opening and closing structure for the TV cabinet described above.

[0011] According to some embodiments of the present invention, a mounting bracket is fixed to the back of the cabinet door. The mounting bracket includes a slide rail and a connecting bracket. The connecting bracket is connected to the television by fixing screws. The slide rails consist of two sections, which are horizontally fixed to the back of the cabinet door. According to some embodiments of the present invention, at least two connecting frames are used. The connecting frames are arranged vertically, and the two ends of the connecting frames are respectively slidably connected to the two slide rail frames. Each connecting frame can slide independently in the lateral direction.

[0012] According to some embodiments of the present invention, the slide rail includes a back plate, a bottom plate, and a front plate, wherein the back plate is fixed to the back of the cabinet door. According to some embodiments of the present invention, one end of the base plate is horizontally connected to the bottom end of the back plate, and the other end of the base plate is connected to the front plate, so that the base plate and the front plate form a T-shape.

[0013] According to some embodiments of the present invention, the end of the connecting frame extends vertically into an opening hook, the opening hook including a slot one, the end of the connecting frame is provided with a slot two, the slot two being located below the slot one, the slot one and the slot two being respectively used to accommodate the upper and lower sides of the front plate.

[0014] According to some embodiments of the present invention, the cabinet door has a wire hole.

[0015] The present invention has at least the following beneficial effects: 1. This hinge structure completely abandons the conventional method of connecting cabinet doors and cabinet bodies by directly screwing in fixing screws, instead employing a graded force transmission connection mechanism. Specifically, it adds a first and a second fixing component, which are first securely installed on the cabinet door and cabinet body respectively, and then the hinge body is connected to these two pre-installed fixing components. In this way, the mechanical force generated when the door opens and closes or bears loads is mainly borne and transmitted by the first and second fixing components, effectively avoiding the fixing screws directly bearing the main load. This fundamentally solves the problem in traditional structures where fixing screws are prone to plastic deformation due to long-term direct stress, and may even gradually be pulled out of the wooden cabinet door or cabinet body.

[0016] 2. To ensure extremely high reliability and durability of the connection between the hinge and the first and second fixing components, this structure further incorporates an interlocking design. Specifically, the hinge has a specially designed insert plate, while the first and second fixing components are correspondingly machined with locking slots one and two. During assembly, insert plate one and insert plate two precisely engage with these two locking slots, forming a rigid connection similar to a traditional mortise and tenon joint. This ensures that the edges of insert plate one and locking slot one, and the edges of insert plate two and locking slot two, fit together and press against each other, creating a frictional self-locking mechanism. This tight mechanical interlocking not only guarantees an absolutely secure connection but also fundamentally prevents loosening or even separation between the hinge and the two fixing components under long-term vibration or load, greatly enhancing the overall integrity of the connection node.

[0017] 3. To ensure stable mounting of televisions of various sizes, this mounting system features two independently sliding connecting brackets. These brackets can move smoothly horizontally, allowing for flexible adjustment of the actual distance between them. This method enables the system to precisely fit the back panel mounting holes of televisions of different sizes on the market, ensuring accurate alignment and locking of the connection points, providing broad and reliable installation support for televisions of various sizes.

Detailed Implementation

[0020] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] In the description of this invention, the terms "first," "greater than," "less than," and "exceeding" are understood to exclude the stated number. The use of "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, the quantity of indicated technical features, or the order of the indicated technical features.

[0022] like Figures 1 to 4 As shown, the opening and closing structure for the TV cabinet includes a hinge 1, a first fixing member 2, and a second fixing member 3. The hinge 1 includes an upper page 11A and a lower page 12A, which are arranged vertically. The upper page 11A includes an embedded plate 111A, and the lower page 12A includes an embedded plate 121A. The first fixing member 2 is fixed to the cabinet door 101 and is provided with a locking slot 21. The second fixing member 3 is fixed to the cabinet body 102 and is provided with a locking slot 34. The embedded plate 111A and the locking slot 21, and the embedded plate 121A and the locking slot 34 form a fitting connection.

[0023] In use, firstly, fix the first fixing member 2 and the second fixing member 3 to the cabinet door 101 and the cabinet body 102 respectively. Then, embed the first embedding plate 111A of the hinge 1 into the first lock slot 21, and then embed the second embedding plate 121A of the hinge 1 into the second lock slot 34, so that the first embedding plate 111A and the first lock slot 21, and the second embedding plate 121A and the second lock slot 34 form a fitting connection, thus completing the installation between the cabinet door 101 and the cabinet body 102.

[0024] This opening and closing structure completely abandons the conventional method of connecting the traditional hinge 1 by directly screwing the fixing screw into the cabinet door 101 and the cabinet body 102. Instead, it adopts a hierarchical force transmission connection mechanism. Specifically, by adding a first fixing member 2 and a second fixing member 3, these two fixing members are first securely installed on the cabinet door 101 and the cabinet body 102 respectively, and then the hinge 1 body is connected to these two pre-installed fixing members. In this way, the mechanical force generated when the door opens and closes or bears a load will be mainly borne and transmitted by the first fixing member 2 and the second fixing member 3, thus effectively avoiding the fixing screw directly bearing the main load. This fundamentally solves the failure problem in traditional structures where fixing screws are prone to plastic deformation due to long-term direct stress, and may even be gradually pulled out of the wooden cabinet door 101 or cabinet body 102.

[0025] Secondly, to ensure the high reliability and durability of the connection between hinge 1 and the first fixing member 2 and the second fixing member 3, an interlocking design is further introduced into the structure. Specifically, hinge 1 is provided with a specially designed embedded plate 13, while the first fixing member 2 and the second fixing member 3 are respectively machined with locking slot 1 21 and locking slot 2 34. During assembly, embedded plate 1 111A and embedded plate 2 121A will precisely engage with these two locking slots respectively, thereby forming a rigid connection similar to a traditional mortise and tenon structure. The edges of embedded plate 1 111A and locking slot 1 21, and the edges of embedded plate 2 121A and locking slot 2 34 are tightly pressed against each other. When the friction between the two objects reaches a level sufficient to counteract the external driving force, the relative sliding between the objects will be effectively prevented. This phenomenon forms friction self-locking. This means that under specific contact conditions and loading states, even if there is a tendency or force to cause relative motion to be applied to the system, the friction between the contact surfaces is sufficient to completely overcome it, thus keeping the object in a stationary state or a stable relative position, and preventing sliding displacement. This tight mechanical interlock not only ensures the absolute tightness of the connection, but also fundamentally prevents the loosening or even separation that may occur between the hinge 1 and the two fasteners under long-term vibration or load, greatly enhancing the integrity of the connection node.

[0026] Therefore, thanks to the aforementioned dual structural optimizations, this novel hinge 1 structure, in addition to ensuring the cabinet door 101 can smoothly and flexibly complete daily opening and closing operations, has a core advantage in its ability to stably withstand continuous and significant concentrated loads generated by things like a suspended television set 103. During prolonged use, the cabinet door 101 supported by this hinge 1 is extremely unlikely to experience common problems such as overall deformation or lateral sagging due to connection point failure, and completely eliminates the risk of the cabinet door 101 falling off entirely. This gives its overall structure long-term stability, significantly eliminating obvious safety hazards such as the sudden fall of the cabinet door 101 or the fall of the television set 103 that could be caused by connection component failure, thereby greatly improving the safety and lifespan of the furniture product.

[0027] Reference Figures 5 to 9 Both the upper page 11A and the lower page 12A include an arc-shaped plate 14, which is used to connect with the first embedded plate 111A and the second embedded plate 121A.

[0028] Specifically, the arc-shaped plate 14 is symmetrically provided with two insertion ports 141, which are adjacent to the ends of the insertion plate 13. Both lock opening 1 21 and lock opening 2 34 include a second insertion opening 1A and an insertion part 2A. The end of the first insertion plate 111A or the second insertion plate 121A is inserted into the second insertion opening 1A, and the insertion part 2A is inserted into the first insertion opening 141.

[0029] This creates multiple limiting mechanisms between the embedded plate 13 and the curved plate 14, further restricting their relative displacement. Even if the cabinet 102 is subjected to loads from the hanging equipment for a long time, there will be no relative misalignment between the curved plate 14 and the embedded plate 13, further enhancing the stability of the overall structure and preventing the hinge 1 from becoming loose or deformed.

[0030] Reference Figure 4 The curvature of the upper arc plate 14 is opposite to that of the lower arc plate 14, forming a cross shape.

[0031] This reverse bending and crossing design allows the upper and lower sets of leaf blades 11 to form a mutually balancing structure during the opening and closing of the cabinet door 101. When the cabinet door 101 is suspending heavy equipment, the upper and lower arc plates 14 can distribute the load transmitted by the cabinet door 101, avoiding excessive stress on a single part that could cause fatigue deformation. At the same time, in conjunction with the aforementioned multi-interlocking and limiting structure, the entire hinge 1 maintains the overall structural stability under long-term repeated opening and closing and continuous load-bearing conditions, preventing the leaf blades 11 from shifting or deforming, and further ensuring the long-term reliability of the opening and closing structure.

[0032] Reference Figure 9The hinge 1 also includes a shaft 12, and the leaf 11 is provided with a sleeve 15 along the longitudinal axis. The shaft 12 is vertically inserted into the two sleeves 15, so that the two blades 11 are connected in series, and the two blades 11 can rotate relative to each other with the shaft 12 as the axis.

[0033] Reference Figure 2 , 4 The second fastener 3 includes a first plate 31, a second plate 32, and a third plate 33. The first plate 31 and the second plate 32 are perpendicular to each other, and the second plate 32 and the third plate 33 are perpendicular to each other. The first plate 31 is located behind the second plate 32, and the third plate 33 is located in front of the second plate 32. The first plate 31 is fixedly connected to the cabinet 102. The third plate 33 is provided with a second lock 34. The second plate 32 is used to connect the first plate 31 and the third plate 33 to form a stable integrated structure.

[0034] A reinforcing plate 35 is fastened between plate 1 31 and plate 2 32, making the combination of plate 1 31, plate 2 32 and reinforcing plate 35 triangular. Through the installation of reinforcing plate 35, plate 1 31, plate 2 32 and reinforcing plate 35 together form a stable combination that is approximately triangular, further enhancing the stability of the second fastener 3 structure.

[0035] Reference Figure 10 A TV cabinet includes a cabinet body 102 and a cabinet door 101. A TV 103 is fixedly installed on the cabinet door 101. An opening and closing structure is installed between the cabinet body 102 and the cabinet door 101. The opening and closing structure adopts the opening and closing structure used for TV cabinets described above.

[0036] Reference Figures 12 to 14 To facilitate the installation of the television 103, a mounting bracket 4 is fixed on the back of the cabinet door 101. The mounting bracket 4 includes a slide bracket 41 and a connecting bracket 42. The connecting bracket 42 is connected to the fixing holes on the back of the television 103 by fixing screws to achieve the fixed installation of the television 103.

[0037] Two slide rails 41 are used, and the two slide rails 41 are horizontally fixed to the back of the cabinet door 101. At least two connecting frames 42 are used, and the connecting frames 42 are vertically set. The two ends of the connecting frames 42 are slidably connected to the two slide rails 41 respectively. Each connecting frame 42 can slide independently in the horizontal direction.

[0038] To ensure secure mounting of televisions 103 of various sizes, the mounting system incorporates two independently sliding connecting brackets 42. These two brackets 42 can move smoothly horizontally, allowing for flexible adjustment of the actual spacing between them. In this way, the system can precisely fit the mounting holes on the backplates 411 of televisions 103 of different sizes available on the market, ensuring accurate alignment and locking of the connection points, providing broad and reliable installation support for televisions 103 of various sizes.

[0039] Reference Figure 15 Specifically, the slide rail 41 includes a back panel 411, a bottom panel 412, and a front panel 413. The back panel 411 is fixed to the back of the cabinet door 101. One end of the base plate 412 is horizontally connected to the bottom end of the back plate 411, and the other end of the base plate 412 is connected to the front plate 413, so that the base plate 412 and the front plate 413 form a T shape. An opening hook 421 extends vertically from the end of the connecting frame 42. The opening hook 421 includes a first slot 422. The end of the connecting frame 42 is provided with a second slot 423. The second slot 423 is located below the first slot 422. The upper side of the front plate 413 of the slide frame 41 is accommodated in the first slot 422, while the lower side is accommodated in the second slot 423, thereby forming a stable and slidable connection.

[0040] Further instructions on the installation steps for mounting bracket 4: 1. First, fix the two connecting brackets 42 to the back of the cabinet door 101; 2. Insert the upper and lower sides of the front plate 413 into slot 1 422 and slot 2 423 simultaneously, so that the connecting frame 42 is installed on the slide frame 41. 3. Install connecting screws on the connecting bracket 42. The connecting screws pass through the cabinet door 101 and connect with the fixing holes on the back of the TV 103 to achieve the fixed installation of the TV 103.

[0041] To facilitate the passage and concealment of the power cord and signal cable of the television 103, a cable passage hole 104 is specially made on the cabinet door 101.
