Technical Field
[0001] This utility model relates to the field of hinge technology, specifically to a novel hinge structure. Background Technology
[0002] Hinges, as a common rotating connection mechanism, are widely used in various products, such as packaging boxes, cabinet doors, and flip-top electronic devices. Traditional hinges mostly adopt a one-piece structure, directly connecting to the rotating shaft via a fixed base. While simple in structure, this design suffers from poor installation flexibility, limited applicability, and insufficient structural strength. Especially in high-end packaging boxes or precision equipment, traditional hinges are often exposed on the product surface, affecting aesthetics and making them susceptible to damage from external impacts. Although some improved hinges have emerged in existing technologies, these designs are often complex in structure and high in cost, and fail to fundamentally solve the core problems of low modularity, inconvenient installation, and difficulty in balancing structural strength.
[0003] Therefore, there is an urgent need for a new type of hinge structure that combines modularity, high strength, good concealment, and convenient installation. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a novel hinge structure. Through the combined design of a first hinge component, a second hinge component, and a connector, the hinge function is modularized and integrated, improving installation flexibility and structural strength. At the same time, it ensures that the hinge can be completely hidden inside the product when closed, enhancing aesthetics and practicality.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel hinge structure includes a first hinge assembly, a second hinge assembly, and a connecting body. The first hinge assembly and the second hinge assembly are hinged to each other through a connecting structure, and each of the first hinge assembly and the second hinge assembly is connected to a connecting body. The first hinge assembly and the second hinge assembly are rotatably connected to their respective connecting bodies.
[0006] Furthermore, the first hinge assembly and the second hinge assembly are rotatably connected to their respective connecting bodies via a pivot.
[0007] Furthermore, the first hinge assembly includes a first hinge member I and a first hinge member II arranged parallel to each other and spaced apart, and the second hinge assembly includes a second hinge member I and a second hinge member II arranged parallel to each other and spaced apart. The connecting structure is a connecting pin, and the first hinge member I, the first hinge member II, the second hinge member I, and the second hinge member II are respectively provided with connecting pin holes for the connecting pin to pass through.
[0008] Furthermore, one end of the first hinge member I and the first hinge member II are connected to each other through a first stepped shaft, and the other end of each is provided with a mounting hole for the rotating shaft. One end of the second hinge member I and the second hinge member II are connected to each other through a second stepped shaft, and the other end of each is provided with a mounting hole for the rotating shaft.
[0009] Furthermore, the connecting body is a columnar structure with a through groove at its end, the through groove being used to accommodate the first stepped shaft or the second stepped shaft.
[0010] Furthermore, the connecting body is also provided with a first clearance groove adapted to the first hinge member I or the second hinge member I, and a second clearance groove adapted to the first hinge member II or the second hinge member II. The first clearance groove and the second clearance groove have corresponding through holes on their opposite sidewalls. The rotating shaft passes through the through hole of the sidewall of the first clearance groove of the connecting body, the rotating shaft mounting hole of the first hinge assembly or the second hinge assembly, and the through hole of the sidewall of the second clearance groove of the connecting body in sequence, thereby rotatably assembling the hinge assembly and the connecting body together.
[0011] Furthermore, the outer peripheral surface of the connector is provided with an anti-slip structure.
[0012] Furthermore, the anti-slip structure is one of knurling, mesh texture, protrusions, or grooves.
[0013] Furthermore, the outer peripheral surface of the connector is provided with symmetrically arranged positioning structures.
[0014] Compared with existing technologies, the technical solution of this patent achieves the following beneficial effects: 1. The modular design of the hinge function is achieved through the separate design of the first hinge assembly, the second hinge assembly, and the two connecting bodies. The two hinge assemblies can be independently installed on two objects that need to rotate relative to each other via the connecting bodies, which greatly improves the application flexibility and installation convenience of the mechanism.
[0015] 2. Both the first and second hinge assemblies adopt a double-link structure and are hinged by a connecting pin to form a robust four-link mechanism, which significantly enhances the overall structural strength and load-bearing capacity and is not easily deformed or damaged.
[0016] 3. A rotating shaft is used to achieve the rotational connection between the hinge assembly and the connecting body. Combined with the avoidance groove design, it ensures that there is no motion interference during the entire rotation process, and achieves smooth and stable rotation at ultra-large angles or the entire range.
[0017] 4. The entire hinge structure can be embedded inside the product, making the hinge invisible when the product is closed, resulting in a neat and beautiful appearance and enhancing the product's grade.
[0018] 5. The anti-slip and positioning structures on the outer circumference of the connecting body effectively increase the friction and positioning accuracy between the connecting body and the mounting base, preventing loosening during use. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] See Figure 1-6As shown, this embodiment provides a novel hinge structure, including a first hinge assembly 1, a second hinge assembly 2, and connecting bodies 3. The first hinge assembly 1 and the second hinge assembly 2 are hinged to each other via a connecting structure, and each of the first hinge assembly 1 and the second hinge assembly 2 is connected to a connecting body 3. The first hinge assembly 1 and the second hinge assembly 2 are rotatably connected to their respective connecting bodies 3. Through the separate design of the first hinge assembly 1, the second hinge assembly 2, and the two connecting bodies 3, the modularity and integration of the hinge function are achieved. This structure allows the two hinge assemblies to be independently installed on two objects that need to rotate relative to each other, such as a box and a lid, via connecting bodies, greatly improving the application flexibility and installation convenience of the mechanism, and providing a foundation for subsequent structural optimization.
[0023] The first hinge assembly 1 and the second hinge assembly 2 are rotatably connected to their respective connecting bodies 3 via a rotating shaft 4. Using a rotating shaft 4 to achieve the rotatable connection between the hinge assembly and the connecting body ensures smoothness and stability during rotation, while also facilitating manufacturing and assembly, reducing production costs and process complexity.
[0024] The first hinge assembly 1 includes two parallel and spaced-apart first hinge members I 11 and II 12. The second hinge assembly 2 includes two parallel and spaced-apart second hinge members I 21 and II 22. The connecting structure is a connecting pin 5. Connecting pin holes (13, 23) are correspondingly provided on the first hinge members I 11, I 12, I 21, and II 22 for the connecting pin 5 to pass through. By designing both the first and second hinge assemblies as consisting of two parallel and spaced-apart hinge members and hinged together by a connecting pin 5, a robust double-link structure is formed, greatly enhancing the overall structural strength and load-bearing capacity of the hinge mechanism.
[0025] One end of the first hinge member I11 and the first hinge member II12 are connected to each other via a first stepped shaft 61, and the other end of each is provided with a mounting hole for a rotating shaft 4. One end of the second hinge member I21 and the second hinge member II22 are connected to each other via a second stepped shaft 62, and the other end of each is provided with a mounting hole for a rotating shaft 4. By connecting one end of each of the two hinge members via the first stepped shaft 61 and the second stepped shaft 62, the parallelism and relative positional accuracy between the two hinge members in the first and second hinge assemblies are ensured. The stepped shaft itself plays a dual role of positioning and connection.
[0026] The connector 3 has a columnar structure and a through groove 34 at its end. The through groove 34 is used to accommodate the first stepped shaft 61 or the second stepped shaft 62. By opening the through groove 34, the stepped shaft can be accommodated, avoiding interference or damage that may be caused by exposure, and making the appearance neater.
[0027] The connecting body 3 is also provided with a first clearance groove 31 adapted to the first hinge member I11 or the second hinge member I21, and a second clearance groove 32 adapted to the first hinge member II12 or the second hinge member II22. Through holes 33 are correspondingly opened on the opposite sidewalls of the first clearance groove 31 and the second clearance groove 32. The rotating shaft 4 passes sequentially through the through hole 33 on the sidewall of the first clearance groove 31 of the connecting body 3, the rotating shaft mounting hole of the first hinge assembly 1 or the second hinge assembly 2, and the through hole 33 on the sidewall of the second clearance groove 32 of the connecting body 3, thereby rotatably assembling the hinge assembly and the connecting body 3 together. The clearance groove provides clearance space, ensuring that there is no movement interference between the component and the connecting body during the entire rotation process, thus achieving smooth rotation at ultra-large angles or throughout the entire range. By opening through holes on the sidewalls of the clearance grooves and cooperating with the rotating shaft, the hinge assembly, the rotating shaft, and the connecting body are firmly combined into a whole.
[0028] The outer peripheral surface of the connector 3 is provided with an anti-slip structure 35, which can be one of knurling, mesh texture, protrusions, or grooves. This significantly increases the friction between the connector and the object being installed, such as the inner wall of a box or lid.
[0029] The outer periphery of the connector 3 is also provided with symmetrically arranged positioning structures 36, which are either semi-circular or square. The positioning structures 36 can serve as positioning points when the connector is inserted into a predetermined position.
[0030] The working principle of this utility model is as follows: The first hinge assembly 1 and the second hinge assembly 2 are rotatably connected to their respective connecting bodies 3, and the two hinge assemblies are hinged together by a connecting pin 5. The two connecting bodies 3 are respectively embedded in the objects that need to rotate relative to each other (such as the box body and the box lid). When closed, the hinge mechanism is hidden inside the box. During rotation, the two hinge assemblies rotate around the axis of the connecting pin 5, while the connecting body 3 rotates around the pivot 4, realizing dual-axis linkage. The entire rotation process is smooth and interference-free. The clearance groove provides movement space for the hinge components, and the through groove 34 accommodates the stepped shaft, further optimizing the structural compactness.
