Description

Technical Field

[0001] This utility model relates to the technical field of upward-opening door hinges, specifically an upward-opening door hinge with quick-installation auxiliary positioning function. Background Technology

[0002] Upward-opening door hinges are a common furniture connection component, mainly used in wall cabinets, hanging cabinets, and other applications where cabinet doors need to be opened upwards.

[0003] Among them, patent number 2025100781127 proposes an upward-opening door hinge and its design method, which includes a linkage assembly, a drive module, and a fixed plate. The linkage assembly includes an input linkage, a fixed-length linkage, an adjusting linkage, a first support linkage, a second support linkage, a third support linkage, and an output linkage. The input linkage is movably hinged to the drive module, the fixed plate, and the fixed-length linkage. The adjusting linkage is movably hinged to the fixed plate and the fixed-length linkage. The first support linkage is movably hinged to the adjusting linkage, the second support linkage, and the output linkage. The third support linkage is movably hinged to the second support linkage and the output linkage. The upward-opening door hinge adopts a linkage structure with a three-support mechanism. The three-support mechanism can provide multi-directional support for the movement of the linkage during hinge operation and play an auxiliary or pushing role when the hinge is suspended and the door is closed. At the same time, the design method of this upward-opening door hinge adds a state compensator. Utilizing a state compensation mechanism similar to the upper and lower tolerance principle of metal processing, the hinge's design points P and P' are adjusted accordingly. α It transforms a precise point value into a dynamic point that can fluctuate within a small range.

[0004] However, the traditional analytical method cannot solve the overlapping area of ​​closing force and support force. By transforming it into position tracking of the moving point on the adjusting linkage, and by establishing a model and optimizing the model with a state compensator, the balance between closing force and support force is effectively solved. However, there are still some application scenarios for the upward hinge: there will be a protruding edge on the upper surface of the cabinet top plate. The thickness of the top plate, the installation position of the upward hinge, and the relative installation position of the upward hinge and the door panel will all affect the cover position. At the same time, the length of the protruding edge and the thickness of the door panel will also affect the opening angle of the upward hinge. Therefore, it is necessary to achieve rapid installation and positioning for existing products. Utility Model Content

[0026] The present invention will now be further described with reference to the accompanying drawings.

[0027] According to the appendix Figures 1 to 12As shown, the upward-opening door hinge of this utility model with quick-installation auxiliary positioning function includes a hinge base 3 installed on the cabinet body 1 and a hinge arm 4 installed on the door panel 2. The hinge arm 4 is hinged to the hinge base 3. The top plate of the hinge base 3 has a protruding flange 11. A transmission assembly for the hinge arm 4 to flip up and down on the hinge base 3 is connected between the hinge base 3 and the hinge body 1. The quick-installation positioning device includes a side wrapping part 5, an upper connecting cover 6, and an auxiliary mounting block 7. The side wrapping part 5 is located on one side of the hinge base 3, the upper connecting cover 6 is located on the top of the hinge base 3, and the auxiliary mounting block 7 is located on the top plate inside the cabinet body 1. A first-level locking fastening group 8 is provided between the side wrapping part 5 and the auxiliary mounting block 7, and a second-level locking fastening group 9 is provided between the upper connecting cover 6 and the auxiliary mounting block 7. By successively fastening the first-level locking fastening group 8 and the second-level locking fastening group 9, the hinge base 3 can be quickly positioned and assembled.

[0028] Through the structure of the side wrapping piece 5, the auxiliary mounting block 7, and the first-level locking buckle assembly 8 and the second-level locking buckle assembly 9, the hinge seat 3 can be quickly positioned and assembled onto the cabinet 1 even when the top plate of the cabinet 1 has a protruding edge 11. The structure is simple, the operation is convenient and quick, and it is beneficial to the reliability and practicality during the opening and closing of the door panel 2, ensuring the quality of product use.

[0029] Reference Figures 1 to 12 As shown, further detailed, the first-level locking fastening assembly 8 includes a first annular buckle 81 and an annular groove 82. The annular groove 82 is located on the top of the side wrapping member 5, and the first annular buckle 81 is located at the left end of the auxiliary mounting block 7. The first annular buckle 81 is fastened to the annular groove 82, forming a first-level locking fastening assembly 8 for quickly fastening the left end of the hinge seat 3 to the cabinet body 1.

[0030] Furthermore, the second-level locking fastening assembly 9 includes a second annular buckle 91 and a linear groove 92. The linear groove 92 is located on the upper surface of the upper connecting cover 6, and the second annular buckle 91 is located at the right end of the auxiliary mounting block 7. The second annular buckle 91 is fastened to the linear groove 92, and at the same time, it forms a second-level locking fastening assembly 9 for quickly fastening the right end of the hinge seat 3 to the cabinet 1.

[0031] In the optimized solution, the first annular buckle 81 is fastened to the annular groove 82 by coaxial engagement; the second annular buckle 91 is fastened to the linear groove 92 by linear sliding.

[0032] During assembly, the first annular buckle 81 and the annular groove 82 are first coaxially engaged to achieve the first-level locking engagement 8. Then, the second annular buckle 91 is linearly slid into the linear groove 92 to achieve the second-level locking engagement. It is worth noting that the ideal position for the second annular buckle 91 is when it slides into the auxiliary mounting block 7 and is centered relative to the upward-opening door hinge. The structure is simple and allows for quick positioning and assembly of the upward-opening door hinge even when the top plate of the cabinet 1 has a protruding edge 11. This facilitates operation and enhances the stability and reliability of the structure.

[0033] In addition, the side wrapping piece 5 is fixedly connected to the left side of the hinge 3 by rivets, and the upper connecting cover 6 is interference-fitted with the upper surface of the hinge 3.

[0034] Furthermore, the auxiliary mounting block 7 is provided with anti-slip texture 71 to increase friction, and the anti-slip texture 71 is provided on the right end of the auxiliary mounting block 7.

[0035] In this way, the auxiliary mounting block 7, side wrapping parts 5, and upper connecting cover 6 of this structure optimize the structural assembly, prevent parts from falling off during operation, and greatly enhance the structural stability.

[0036] Based on the above description of the scheme in this application, and referring to Figures 1 to 12 As shown, this application also establishes a calculation model for the limiting space size, such as... Figure 12 As shown. For ease of description, the physical quantities and their names are defined as follows:

[0037] D - Door panel thickness 2;

[0038] FH - Door panel height 2;

[0039] B - Top plate thickness;

[0040] C - Cabinet depth;

[0041] θ - Door panel 2 opening angle;

[0042] [Z] - Allowed for a 11-inch length of the protruding edge;

[0043] [X] - Permitted length;

[0044] [Y] - Permissible height, θ∈(90°, 107°];

[0045] [A] - Permissible height, θ∈(0°, 90°);

[0046] Based on the product's positioning dimensions and installation, different values ​​for D and B among the above physical quantities will affect X, and different values ​​for FH and D will affect [Y] and [A]. Therefore, the relationship between B, D, and X must first be determined. Taking an opening angle of 107° as an example, see the table below:

[0047]

[0048] [X] is minimally affected by the opening angle, [X] = C + FH * cos17° + 12.

[0049] When the opening angle is 107°, [Y] = FH * 0.29 - 13 + D.

[0050] Similarly, when the opening angle is 100°, [Y] = FH * 0.17 - 13 + D.

[0051] When the opening angle is 75°, [A] = FH * 0.23 + 10 - D.
