[0031] Hinges, also known as hinges or hinges, are often configured to fold in two. They are components that connect two parts of an object and enable movement. In the existing furniture, door, and window manufacturing industries, hinges are key components that connect two movable parts. Their durability and user experience directly affect the overall quality of the product. In related art, hinges are equipped with two leaves that are rotatably connected by a sleeve and a latch to enable the hinge to open and close. During the opening and closing process, noise and vibration are easily generated, and the wear between the various hinge structures is large. The opening and closing action is unstable, which can easily affect normal opening and closing. This leads to a poor user experience and a short service life.

[0032] To address this issue, a variety of damping hinges have emerged on the market. However, most are complex and expensive, and their damping effect can weaken or even fail after prolonged use, making them difficult to meet the market's comprehensive demands for durability, stability, and affordability. In particular, existing damping hinges often utilize mechanical or hydraulic damping mechanisms. These mechanisms are not only complex in structure, increasing manufacturing difficulty and cost, but are also susceptible to environmental factors such as temperature and humidity during long-term use, resulting in unstable damping performance. Furthermore, mechanical damping mechanisms often wear out, requiring regular maintenance or replacement, further increasing operating costs.

[0033] The following is the attached Figure 1 To the attached Figure 5 , describing the durable damping hinge of the embodiment of the utility model, which has good buffering and damping effect, stable opening and closing action, small wear and tear, and good durability.

[0034] Reference Figures 1 to 5, a durable damping hinge according to an embodiment of the present invention is characterized in that it includes a first leaf 100, a second leaf 200, a latch 300 and a damping assembly 400, wherein two coaxial first sleeves 110 are provided at one side edge of the first leaf 100, each first sleeve 110 is provided with a first rotation hole 111 matching the latch 300, and two coaxial second sleeves 210 are provided at one side edge of the second leaf 200, each second sleeve 210 is provided with a second rotation hole 211 matching the latch 300, and the latch 300 is inserted into each first rotation hole 111 and the second rotation hole 211, all first sleeves 110 and second sleeves 210 are coaxially arranged, and the latch 300 can rotate relative to the first sleeve 110 and the second sleeve 210, thereby realizing relative rotation between the first leaf 100 and the second leaf 200, and each second sleeve 2 10 are respectively arranged adjacent to the end of the corresponding first sleeve 110 away from the center of the first leaf 100, and each first sleeve 110 is provided with n first receiving grooves 112 at one end away from the adjacent second sleeve 210, where n is an integer greater than 1, and all the first receiving grooves 112 are evenly distributed along the circumferential trajectory around the latch 300, and equal intervals are formed between each two adjacent first receiving grooves 112, and the first receiving grooves 112 of the two first sleeves 110 are arranged opposite to each other, and each second sleeve 210 is provided with n second receiving grooves 212 respectively matching with each first receiving groove 112, and all the second receiving grooves 212 are evenly distributed along the circumferential trajectory around the latch 300, and equal intervals are formed between each two adjacent second receiving grooves 212, and the first receiving grooves 112 of the two second sleeves 210 are arranged opposite to each other;

[0035] The damping assembly 400 is provided with two groups, each group of damping assemblies 400 is used to connect two corresponding groups of first sleeves 110 and second sleeves 210. For each group of damping assemblies 400 and the corresponding adjacent first sleeves 110 and second sleeves 210, the damping assembly 400 includes a first magnet 410, a second magnet 420, a first end cover 430 and a second end cover 440. There are n first magnets 410 and second magnets 420. Each first magnet 410 is respectively provided in each corresponding first receiving groove 112. One side of the first end cover 430 is provided with n first positioning blocks 430. 1. Each first positioning block 431 is respectively engaged with the notch of each corresponding first receiving groove 112. The first end cover 430 is located outside the end of the first sleeve 110 away from the adjacent second sleeve 210. The first positioning block 431 is engaged with the notch of the first receiving groove 112 to realize the connection between the first end cover 430 and the first sleeve 110. The first end cover 430 is provided with a rotational clearance hole 432 for inserting the latch 300. The latch 300 is also inserted into the rotational clearance hole 432. Each second magnet 420 is respectively arranged in each corresponding second receiving groove 212. The second The magnet 420 is located in the near-field magnetic field of the first magnet 410, so that a magnetic interaction force is formed between the first magnet 410 and the second magnet 420. Preferably, the first magnet 410 is located in the near-field magnetic field of the second magnet 420, and the distance between the bottom of the first receiving groove 112 and the end of the first sleeve 110 away from the center of the first leaf 100 is d, and the distance between the bottom of the second receiving groove 212 and the end of the second sleeve 210 away from the center of the second leaf 200 is D. In application, by setting the sum of d and D to be smaller than the effect of the near-field magnetic field of the first magnet 410 The range is smaller than the range of action of the near-field magnetic field of the second magnet 420, which can effectively ensure the interaction effect between the first magnet 410 and the second magnet 420. One side of the second end cover 440 is provided with n second latching blocks 441, and each second latching block 441 is respectively engaged with the notch of each corresponding second receiving groove 212. The second end cover 440 is located outside the end of the second sleeve 210 away from the adjacent second sleeve 210, and the connection between the second end cover 440 and the second sleeve 210 can be achieved by engaging the second latching block 441 with the notch of the second receiving groove 212.

[0036] The first and second magnets 410 and 420 are provided with a plurality of evenly spaced first and second magnets 410 and 420, respectively, and an intermittent buffering and positioning effect can be formed between the first and second magnets 410 and 420, thereby effectively reducing the wear between the first and second sleeves 110 and 210, thereby improving the durability of the damping hinge. The damping effect is weakly correlated with the usage time, that is, the damping effect is almost unaffected by the usage time, and the damping effect can be effectively maintained when the usage time increases, thereby effectively meeting the market's comprehensive requirements for durability, stability, and economy.

[0037] In addition, by arranging the first receiving groove 112 and the second receiving groove 212 in opposite directions, not only can the stability of the structure be avoided due to direct contact between the first magnet 410 and the second magnet 420, but also the collision wear between the groove structure and the magnet structure on the end of the sleeve can be avoided. The first sleeve 110 and the second sleeve 210 are connected by abutting the flat end faces, which can significantly reduce the wear generated when the first sleeve 110 and the second sleeve 210 rotate relative to each other. It has good durability and long service life. The structure of the damping hinge is compact and reliable, and it is easy to assemble, which can effectively reduce assembly costs and maintenance costs.

[0038] It can be understood that in the same damping assembly 400, the polarity direction of the first magnet 410 and the second magnet 420 is the same, that is, the opposite ends of the first magnet 410 and the second magnet 420 have different polarities, and a mutually attractive magnetic force is formed between the first magnet 410 and the second magnet 420. During the rotation of the first sleeve 110 relative to the second sleeve 210, when the central axes of the first magnet 410 and the second magnet 420 are collinear, a mutual adsorption effect is formed between the relative first magnet 410 and the second magnet 420, thereby forming a damping and buffering effect on the mutual rotation between the first sleeve 110 and the second sleeve 210, which can effectively improve the stability of the rotation movement.

[0039] Conversely, in the same damping assembly 400, the polarity directions of the first magnet 410 and the second magnet 420 can also be set to be opposite, that is, the opposite ends of the first magnet 410 and the second magnet 420 have the same polarity, and a mutually repelling magnetic force is formed between the first magnet 410 and the second magnet 420. During the rotation of the first sleeve 110 relative to the second sleeve 210, when the central axes of the first magnet 410 and the second magnet 420 are collinear, a mutually repelling effect is formed between the relative first magnet 410 and the second magnet 420, thereby forming a damping and buffering effect on the mutual rotation between the first sleeve 110 and the second sleeve 210, which can effectively improve the stability of the rotational movement.

[0040] It is understandable that the first sleeve 110 and the second sleeve 210 are both non-magnetic metal structures. The non-magnetic metal structure can effectively reduce the probability of the first sleeve 110 and the second sleeve 210 being magnetized by the first magnet 410 and the second magnet 420, and can ensure that an intermittent buffering effect can be formed between the equally spaced first magnets 410 and the equally spaced second magnets 420. While ensuring the damping buffering effect, it can effectively reduce the wear between the first sleeve 110 and the second sleeve 210, and can effectively ensure the durability of the damping hinge. Specifically, the first sleeve 110 and the second sleeve 210 are both non-magnetic steel sleeves.

[0041] It can be understood that in each group of damping components 400, n is set to 4, and the four first receiving grooves 112 are evenly distributed at equal intervals along a circular trajectory with the axis of the first rotating hole 111 as the center, that is, the four first receiving grooves 112 are evenly distributed around the first rotating hole 111, and the four second receiving grooves 212 are evenly distributed at equal intervals along a circular trajectory with the axis of the second rotating hole 211 as the center, that is, the four second receiving grooves 212 are evenly distributed around the second rotating hole 211. The four first magnets 410 and the four second magnets 420 of each group of damping components 400 can effectively improve the stability of the damping buffering action.

[0042] It can be understood that the inner wall of the end of each second rotating hole 211 away from the first sleeve 110 is provided with a threaded portion 213, and each second end cover 440 is provided with a screw hole 442. The damping assembly 400 also includes a screw 450, which is threadedly connected to the screw hole 442 and the threaded portion 213.

[0043] Specifically, screw 450 is sequentially inserted into screw hole 442 and second rotary hole 211. The head of screw 450 abuts the side of second end cap 440 away from second sleeve 210. The threaded body of screw 450 engages with threaded portion 213 and screw hole 442, facilitating assembly. The screws 450 of the two damping assemblies 400 are restrained at both ends of the latch 300, effectively limiting the position of the latch 300 relative to the first sleeve 110 and the second sleeve 210, thereby ensuring the stability of the overall damping hinge structure.

[0044] It can be understood that a third sleeve 220 coaxial with the second sleeve 210 is further provided at one side edge of the second leaf 200, and the third sleeve 220 is provided with a third rotating hole 221 matching the latch 300. The latch 300 is also passed through the third rotating hole 221. The third sleeve 220 is located between the two first sleeves 110. The length of the third sleeve 220 is greater than the maximum effective distance of the near-field magnetic field of the first magnet 410. The third sleeve 220 can reduce the mutual influence between the first magnets 410 in the two first sleeves 110, and can effectively ensure the stability of the opening and closing action of the damping hinge.

[0045] In addition, the setting of the third sleeve 220 can form sufficient installation space between the two first sleeves 110, thereby providing sufficient clearance space for the installation of the first magnet 410 and the first end cover 430. First, insert the first magnet 410 into the corresponding first receiving groove 112, and then insert the first positioning block 431 into the end of the corresponding first receiving groove 112. Then, align the third sleeve 220 and the second sleeve 210 with the first sleeve 110, and then pass the pin 300 through the second rotating hole 211, the first rotating hole 111 and the third rotating hole 221, which can effectively reduce the difficulty of assembly and improve the assembly efficiency.

[0046] It can be understood that the first end cover 430 is a wear-resistant engineering plastic structure. Preferably, the first end cover 430 is a polytetrafluoroethylene end cover structure. By setting the first end cover 430 to be a wear-resistant engineering plastic structure, the wear between the first end cover 430 and the third sleeve 220 can be effectively reduced, thereby effectively improving the durability of the overall structure.

[0047] It is understandable that the first leaf 100 is provided with a first mounting hole 120 and the second leaf 200 is provided with a second mounting hole 230 , and the hinge can be conveniently installed in a target area through the first mounting hole 120 and the second mounting hole 230 .

[0048] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
