Hidden door hinges are often used for fire doors as hidden doors. These hinges, also known as concealed hinges, are designed to be invisible when the door is closed, providing a seamless and aesthetically pleasing appearance. They are different from regular hinges in that they do not protrude from the surface of the door when installed, making them ideal for hidden or secret doors.
Hidden door hinges come in various types to accommodate different door designs and specifications. Some common types include glass hinges, corner hinges, bearing hinges (made of copper or steel), and pipe hinges. Glass hinges are used for glass doors, while corner hinges are used for doors that are set at an angle. Bearing hinges are durable hinges that are suitable for heavy doors, and pipe hinges are mainly used for furniture door panels.
In addition to hinges, there are several other hardware accessories that are used for hidden doors. These include tracks (such as drawer tracks, sliding door tracks, hanging tracks, and glass sliding tracks), latches, door stoppers, ground stoppers, floor springs, door clips, door closers, plate pins, door mirrors, anti-theft buckles, layering materials (such as copper, aluminum, and PVC), bumper beads, and magnetic bumper beads.
Apart from hidden door hardware, there are also various small hardware accessories used for home decoration. Some examples include universal locks, cabinet legs, door noses, air ducts, stainless steel barrels, metal hangers, plugs, curtain rods (made of copper or wood), curtain rod rings (made of plastic or steel), sealing strips, lift drying racks, clothes hooks, and clothes hangers.
When it comes to choosing between hidden door hinges and exposed hinges for invisible doors in home decoration, it ultimately depends on personal preference and the specific design requirements of the project. Hidden hinges are more aesthetically pleasing as they are concealed when the door is closed, providing a seamless appearance. On the other hand, exposed hinges are more commonly used and may offer more options in terms of sizes, styles, and finishes.
The main difference between hinges and hinges is that hinges are generally used for cabinet doors, windows, and other similar applications, while hinges are mechanical devices used to connect two solids and allow rotation between them. Hinges can be made of movable components or foldable materials, and they are commonly installed on doors and windows, as well as cabinets. In terms of material classification, hinges can be divided into stainless steel hinges and iron hinges. Stainless steel hinges are more durable and have a buffer function when closing cabinet doors, minimizing noise and damage.
In terms of home decoration, hinges and hinges serve similar functions but differ in their appearances and applications. Hinges are often visible and can be decorative elements, while hinges are hidden and provide a seamless appearance.
When selecting hinges or hinges for invisible doors, it is important to consider factors such as the weight and size of the door, the desired opening angle, and the overall design aesthetic. Good quality hinges should be made of durable materials such as brass or stainless steel, with a sufficient thickness and precision in their construction. It is important to choose hinges that provide smooth and quiet operation, with a suitable amount of friction and resilience.
In conclusion, hidden door hinges are a popular choice for fire doors as hidden doors due to their seamless appearance and functionality. They are different from regular hinges in that they are concealed when the door is closed, providing an aesthetically pleasing look. When choosing hinges or hinges for invisible doors, it is important to consider factors such as weight, size, and design requirements, and select high-quality hardware accessories that provide durability, smooth operation, and a seamless appearance.

Flexible hinges have gained significant attention in precision devices due to their ability to transmit motion or energy through elastic deformation instead of rigid components. Compared to traditional motion hinges, flexible hinges offer advantages such as high motion resolution, no friction, no lubrication, and a simple manufacturing process. They have been widely used in various precision devices, including projection lithography objective lenses, silicon wafer workbenches, electronic scanning microscopes, space optical remote sensors, and precision and ultra-precision processing. The key parameters of compliant mechanisms, like flexible hinges, directly impact the dynamic characteristics and positioning accuracy of the end. Therefore, extensive research has been conducted to understand the flexibility of flexible hinges. This paper aims to study the flexibility matrix of straight beam rounded flexure hinges, analyze its parameters, and provide a theoretical basis for their design and optimization.
Flexibility Matrix of Straight Beam Rounded Flexure Hinges:
The straight beam rounded flexure hinge consists of a straight beam sheet structure with rounded corners at the hinge's ends to avoid stress concentration. The main geometric parameters include hinge height (h), hinge length (l), hinge thickness (t), and hinge fillet radius (r). To analyze the in-plane deformation of the hinge, an analytical calculation method based on the cantilever beam theory is derived. This method establishes a closed-loop analytical model for the in-plane flexibility matrix of the flexible hinge. Additionally, a simplified calculation formula for the flexibility matrix is provided when the ratio of hinge corner radius to thickness (r/t) is given.
Finite Element Verification:
To validate the derived analytical formula, a finite element model of the straight beam rounded flexure hinge is established using UGNX NASTRAN software. The simulation results of the finite element model are compared with the analytical values of the flexibility matrix parameters. The relative error between the two is analyzed for different variations in the hinge's structural parameters, such as the ratio of hinge length to thickness (l/t) and the ratio of hinge corner radius to thickness (r/t).
Results:
The analysis shows that for l/t ratios greater than or equal to 4, the relative error between the analytical and simulated values of the flexibility matrix is within 5.5%. However, for l/t ratios less than 4, the relative error is relatively large due to the inability to simplify the cantilever beam into a slender beam. This indicates that the closed-loop analytical model is more suitable for large l/t cases.
Regarding the ratio r/t, the analysis reveals that when 0.1 ≤ r/t ≤ 0.5, the relative error between the analytical and simulated values can be controlled within 9%. Additionally, when 0.2 ≤ r/t ≤ 0.3, the relative error can be controlled within 6.5%. These findings demonstrate the accuracy and applicability of the closed-loop analytical model for the flexibility matrix.
The closed-loop analytical model developed in this study provides a theoretical basis for the design and optimization of straight beam rounded flexure hinges. The analysis demonstrated that the model can accurately predict the flexibility matrix parameters when considering variations in hinge length, thickness, and corner radius. These findings will contribute to the advancement of compliant mechanisms and their applications in precision devices.
