Description

Technical Field

[0002] This section provides only background information related to this application to enable those skilled in the art to understand this application more thoroughly and accurately, and it is not necessarily prior art.

[0003] In modern daily life, hardware hinges are widely used in wardrobes and cabinets. In order to improve the comfort of using hinges and extend their service life, soft-close hinges have emerged. They mainly use a buffer device to achieve smooth buffering during the hinge closing process, reducing the noise generated by the collision between the door and the cabinet body when the door closes.

[0004] However, existing hardware hinges lack a buffer function when opening. When the cabinet door opens too quickly, it will have a series of negative effects: First, the cabinet door will hit the adjacent cabinet door, wall, or other obstacles with great impact, causing damage, cracking, and paint peeling to the door panel; Second, the huge impact force will cause the hinge to deform or even break and fail; Third, the violent collision between the cabinet door and the cabinet body will generate a lot of noise, reducing the user experience; Fourth, the rapidly opening cabinet door can easily trap children, pets, etc., posing a certain safety hazard.

[0005] Therefore, there is an urgent need to design a hinge structure with an opening buffer function to solve the above-mentioned problems. Utility Model Content

[0027] (4) The hinge structure of this utility model effectively utilizes the external space and avoids the problem of limited internal space by setting both the first buffer component and the second buffer component outside the hinge cup groove; in addition, by setting the first buffer component and the second buffer component on the two outer sides of the hinge cup groove, the structural layout is more reasonable, the force is more balanced, and it is more compact.

[0028] (5) The hinge structure of this utility model, by setting a first buffer component at the hinge cup and a third buffer component in the hinge arm, enables the hinge structure to have both opening buffer and closing buffer functions, thereby slowing down the opening and closing speed of the cabinet door, avoiding cabinet door pinching or collision accidents, and also preventing the cabinet door from violently hitting other objects, which would damage the cabinet door and hinge structure and extend the service life of the product; in addition, by slowing down the opening and closing speed of the cabinet door, it is also possible to avoid the cabinet door violently hitting and generating huge noise, thereby creating a quiet environment and improving the user experience.

[0031] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0032] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the module or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0034] Example 1 See Figure 1-10 This utility model first provides a hinge structure that enables open buffering, including a hinge cup 1 fixed to the cabinet door and a hinge arm 2 fixed to the cabinet body. A rocker arm assembly is provided between the hinge cup 1 and the hinge arm 2 to achieve hinged opening and closing. It also includes a first buffer assembly 5 disposed on the hinge cup 1. The first buffer assembly 5 includes a first buffer and a first drive block 501 that drives and cooperates with the first buffer. The first drive block 501 is driven and connected to the rocker arm assembly.

[0035] When the hinge cup 1 is opened, the rocker arm assembly can be driven to swing synchronously, and the rocker arm assembly can drive the first drive block 501 to move. When the hinge cup 1 is opened to a certain angle, the rocker arm assembly drives the first drive block 501 to drive the first buffer to perform a buffering effect on the hinge cup 1, thereby realizing the opening buffer.

[0036] Therefore, by setting a first buffer component 5 on the hinge cup 1, when the hinge cup 1 is opened to a certain angle, the first buffer in the first buffer component 5 can buffer the hinge cup 1, thereby slowing down the opening speed of the cabinet door, thus avoiding damage to the cabinet door and hinge structure due to violent impact, and preventing noise generation; in addition, by slowing down the opening speed of the cabinet door, it can also prevent cabinet door pinching accidents and reduce safety hazards.

[0037] See Figure 2 as well as Figure 7-8 The hinge cup 1 also has a groove 101, which is configured to accommodate at least part of the rocker arm assembly when the hinge cup 1 is closed; preferably, the first buffer assembly 5 is located outside the groove 101. In this way, by placing the first buffer assembly 5 outside the groove 101 of the hinge cup 1, the external space is effectively utilized, avoiding the problem of limited internal space, making assembly and disassembly more convenient.

[0038] Preferably, the first buffer assembly 5 is located on the outer side of the groove 101; the rocker arm assembly includes an outer rocker arm 3, one end of which is hinged to the hinge cup 1 and located inside the groove 101, and the other end of which is hinged to the hinge arm 2; the first drive block 501 is hinged to the hinge cup 1 and located on the outer side of the groove 101; one side of one end of the outer rocker arm 3 is connected to the first drive block 501 in a transmission connection.

[0039] Specifically, it also includes a first drive shaft 6 that passes through and is linked to the first drive block 501. A first clearance hole 102 is provided on one side of the hinge cup 1, and a first mounting hole 301 is provided on one side of one end of the outer rocker arm 3. The first drive shaft 6 passes through the first clearance hole 102 and is snapped into the first mounting hole 301 to achieve a transmission connection with the outer rocker arm 3. Thus, when the hinge cup 1 is driven to open, the outer rocker arm 3 can be driven to swing synchronously, and the outer rocker arm 3 can drive the first drive block 501 to rotate synchronously.

[0040] In this embodiment, the first drive block 501 has a first fixing hole 5011, and the first drive shaft 6 passes through and is fixed in the first fixing hole 5011 to achieve linkage with the first drive block 501.

[0041] Therefore, one side of the outer rocker arm 3 is connected to the first drive block 501 via the first drive shaft 6. When the hinge cup 1 is fully closed, the first drive shaft 6 will be located on the side of the rocker arm assembly. It does not occupy the depth space of the groove 101, so there is no need to increase the depth of the groove 101 of the hinge cup 1, so the thickness of the hinge cup 1 can be made thinner, and it can be assembled onto a thinner door panel, making it more versatile.

[0042] In this embodiment, a first hinge hole 302 is provided on both sides of one end of the outer rocker arm 3, a third hinge hole 5012 is provided on the first drive block 501, and a fourth hinge hole 103 is provided on both sides of the groove 101 of the hinge cup 1. Thus, by using the first hinge shaft 8 to pass through the two first hinge holes 302, the two fourth hinge holes 103 and the third hinge hole 5012 respectively, one end of the outer rocker arm 3 and the first drive block 501 can be hinged to the hinge cup 1.

[0043] See also Figure 2-4 The first buffer is a first hydraulic cylinder 503, which includes a first cylinder body 5031 and a first piston rod 5032 movably mounted on the first cylinder body 5031. When the first piston rod 5032 is driven to compress and move relative to the first cylinder body 5031, it can generate a buffering effect. The first buffer assembly 5 also includes a first transmission plate 502. One end of the first transmission plate 502 is used for transmission connection with the first drive block 501, and the other end of the first transmission plate 502 is used for transmission connection with the first cylinder body 5031 or the first piston rod 5032. Preferably, one end of the first transmission plate 502 is provided with a first protrusion 5021, and the first drive block 501 is provided with a first protrusion 5013. The first protrusion 5021 is used to abut against the first protrusion 5013 to achieve transmission connection. The other end of the first transmission plate 502 is bent into a first bend 5022, which is used to abut against the first piston rod 5032 to achieve transmission connection.

[0044] Therefore, when the hinge cup 1 is opened to a certain angle, the first protrusion 5013 on the first drive block 501 can abut against the first protrusion 5021 on the first transmission plate 502, and then drive the first transmission plate 502 to move. The first bent portion 5022 on the first transmission plate 502 can abut against and compress the first piston rod 5032 to buffer the hinge cup 1 until the hinge cup 1 is fully opened. Conversely, when the hinge cup 1 is closed, it can simultaneously drive the outer rocker arm 3 and the first drive block 501 to rotate and reset. The first drive block 501 disengages from the first transmission plate 502, and the first piston rod 5032 extends and resets, driving the first transmission plate 502 to reset and move until the first piston rod 5032 is fully reset.

[0045] Of course, it should be noted that in other embodiments, the first cylinder 503 can also be installed in reverse, and the first cylinder body 5031 can be compressed by the first transmission plate 502 to produce a buffering effect on the hinge cup 1, which can also achieve the same technical effect, and is not limited here.

[0046] See Figure 2-3 as well as Figure 5 The hinge structure also includes a first mounting base 7 disposed on one side of the hinge cup 1 and covering the first buffer assembly 5. The first buffer and the first transmission plate 502 are both disposed within the first mounting base 7. One end of the first mounting base 7 has two hooks 704 arranged vertically at intervals, and the hinge cup 1 has two locking holes 106 arranged vertically at intervals. By engaging the two hooks 704 into the two locking holes 106, the first mounting base 7 can be fixed in a limited position. The other end of the first mounting base 7 has a limiting hole 703, and both sides of the groove 101 of the hinge cup 1 have sixth hinge holes 105. By passing the second pin 902 through the limiting hole 703 and the sixth hinge hole 105 respectively, the other end of the first mounting base 7 can be fixed in a limited position, thereby assembling and fixing the first mounting base 7 onto the hinge cup 1.

[0047] Specifically, the first mounting base 7 has a first mounting groove 701 that matches the shape of the first cylinder 5031 and a second mounting groove 702 that matches the shape of the first transmission plate 502. The first hydraulic cylinder 503 is placed in the first mounting groove 701 and the first transmission plate 502 is placed in the second mounting groove 702. When the first mounting base 7 is assembled and fixed on the hinge cup 1, the first hydraulic cylinder 503 and the first transmission plate 502 can be limited and fixed.

[0048] See Figure 2 and Figure 4The rocker arm assembly also includes an inner rocker arm 4 located inside the outer rocker arm 3. One end of the inner rocker arm 4 is hinged to the hinge cup 1, and the other end is hinged to the hinge arm 2. Specifically, the inner rocker arm 4 is bent to form a second hinge hole 401 at the end near the hinge cup 1, and the two side walls of the groove 101 of the hinge cup 1 are provided with fifth hinge holes 104. Thus, by using the first pin 901 to pass through the two fifth hinge holes 104 and the second hinge hole 401 respectively, one end of the inner rocker arm 4 can be hinged to the hinge cup 1.

[0049] In this embodiment, the first pin 901 and the second pin 902 are integrally formed to create a double pin 9.

[0050] Therefore, the opening process of the hinge structure in this embodiment is as follows: When hinge cup 1 is in the fully closed state (e.g.) Figure 7-8 As shown), at this time, the first protrusion 5013 on the first drive block 501 is located at one end of the first clearance hole 102. When the hinge cup 1 is opened, the outer rocker arm 3 can be rotated synchronously. The outer rocker arm 3 can drive the first drive block 501 to rotate counterclockwise until the first protrusion 5013 on the first drive block 501 abuts against the first protrusion 5021 of the first transmission plate 502 (as shown). Figure 9-10 As shown), the hinge cup 1 continues to open, and the first drive block 501 continues to rotate counterclockwise, driving the first transmission plate 502 to compress the first piston rod 5032 to achieve buffering, until the hinge cup 1 is fully open (as shown). Figure 4-5 As shown), at this time, the first transmission plate 502 compresses the first piston rod 5032 to the bottom, and the first protrusion 5013 on the first drive block 501 rotates to the other end of the first clearance hole 102.

[0051] Example 2 See Figure 11-19 In this embodiment, the hinge structure, based on Embodiment 1, additionally includes a second buffer assembly 10 to buffer the closing of the hinge cup 1. The second buffer assembly 10 is disposed on the hinge cup 1 and includes a second buffer and a second drive block 1001 that drives the second buffer. The second drive block 1001 is connected to the rocker arm assembly. When the hinge cup 1 is closed, the rocker arm assembly swings synchronously, and the rocker arm assembly drives the second drive block 1001. When the hinge cup 1 is closed to a certain angle, the rocker arm assembly drives the second drive block 1001 to activate the second buffer, which then buffers the hinge cup 1 to achieve the closing buffer.

[0052] Therefore, by setting the first buffer component 5 and the second buffer component 10 at the hinge cup 1, the hinge structure can simultaneously have the functions of opening buffer and closing buffer, thereby slowing down the opening and closing speed of the cabinet door, avoiding pinching or collision accidents, and also preventing the cabinet door from violently hitting other objects, which would damage the cabinet door and hinge structure and extend the service life of the product. In addition, slowing down the opening and closing speed of the cabinet door can also prevent the cabinet door from violently hitting and generating loud noise, thereby creating a quiet environment and improving the user experience.

[0053] Preferably, the second buffer component 10 is disposed outside the groove 101 of the hinge cup 1, thereby effectively utilizing the external space and avoiding the problem of limited internal space; more preferably, the first buffer component 5 and the second buffer component 10 are disposed on the two outer sides of the groove 101 of the hinge cup 1, thereby enabling the product to be subjected to more uniform force and the layout to be more compact.

[0054] Specifically, it also includes a second drive shaft 11 that passes through and is linked to the second drive block 1001. A second clearance hole 107 is provided on the other side of the hinge cup 1, and a second mounting hole 303 is provided on the other side of one end of the outer rocker arm 3. The second drive shaft 11 passes through the second clearance hole 107 and is engaged in the second mounting hole 303 to achieve a transmission connection with the outer rocker arm 3. The second mounting hole 303 can rotate relative to the second drive shaft 11. Thus, when the hinge cup 1 is closed, the outer rocker arm 3 can be driven to swing synchronously. The outer rocker arm 3 rotates relative to the second drive block 1001 through the second mounting hole 303 until both ends of the second mounting hole 303 abut against the second drive shaft 11, which can drive the second drive block 1001 to rotate.

[0055] In this embodiment, the second drive block 1001 is provided with a second fixing hole 10011, and the second drive shaft 11 passes through and is fixed in the second fixing hole 10011 to achieve linkage with the second drive block 1001.

[0056] In this embodiment, the second drive block 1001 is provided with a seventh hinge hole 10012. By having the first hinge shaft 8 pass through the two first hinge holes 302, the two fourth hinge holes 103 and the seventh hinge hole 10012 respectively, the outer rocker arm 3 and the second drive block 1001 can be hinged to the hinge cup 1.

[0057] Specifically, the second buffer is a second hydraulic cylinder 1003, including a second cylinder body 10031 and a second piston rod 10032 movably mounted on the second cylinder body 10031. The second buffer assembly 10 also includes a second transmission plate 1002, one end of which is connected to the second drive block 1001, and the other end of which is connected to either the second cylinder body 10031 or the second piston rod 10032. When the hinge cup 1 is closed to a certain angle, the second drive block 1001, through the second transmission plate 1002, drives the second cylinder body 10031 or the second piston rod 10032 to extend or retract, thereby buffering the hinge cup 1.

[0058] In this embodiment, when the second piston rod 10032 is compressed and moved relative to the second cylinder 10031, it can generate a buffering effect; preferably, one end of the second transmission plate 1002 is provided with a second protrusion 10021, and the second drive block 1001 is provided with a second protrusion 10013. The second protrusion 10021 is used to abut against the second protrusion 10013 to achieve a transmission connection; the other end of the second transmission plate 1002 is bent with a second bend 10022, and the second bend 10022 is used to abut against the second piston rod 10032 to achieve a transmission connection.

[0059] Therefore, when the hinge cup 1 is closed to a certain angle, the second protrusion 10013 on the second drive block 1001 can abut against the second protrusion 10021 on the second transmission plate 1002, thereby driving the second transmission plate 1002 to move. The second bent portion 10022 on the second transmission plate 1002 can abut against and compress the second piston rod 10032 to buffer the hinge cup 1 until the hinge cup 1 is completely closed. Conversely, when the hinge cup 1 is opened, the outer rocker arm 3 can be driven to rotate and reset simultaneously. The outer rocker arm 3 rotates relative to the second drive block 1001 through the second mounting hole 303. The second piston rod 10032 extends and resets, simultaneously driving the second transmission plate 1002 and the second drive block 1001 to reset. Subsequently, the outer rocker arm 3 abuts against the second drive block 1001 through the second mounting hole 303 to drive the second drive block 1001 to reset and rotate.

[0060] Of course, it should be noted that in other embodiments, the second cylinder 1003 can also be installed in reverse, and the second cylinder body 10031 can be compressed by the second transmission plate 1002 to produce a buffering effect on the hinge cup 1, which can also achieve the same technical effect, and is not limited here.

[0061] In addition, the hinge structure also includes a second mounting base 12 disposed on the other side of the hinge cup 1 and shielding the second buffer assembly 10. The second buffer and the second transmission plate 1002 are both disposed within the second mounting base 12. The structure and assembly method of the second mounting base 12 are the same as those of the first mounting base 7, and will not be described in detail here.

[0062] The closing process of the hinge structure in this embodiment is as follows: When hinge cup 1 is in the fully open state (e.g.) Figure 14-15 As shown), at this time, the second protrusion 10013 on the second drive block 1001 is located at one end of the second clearance hole 107. When the hinge cup 1 is closed, the outer rocker arm 3 can be rotated synchronously. The outer rocker arm 3 drives the second drive block 1001 to rotate counterclockwise until the second protrusion 10013 on the second drive block 1001 abuts against the second protrusion 10021 of the second transmission plate 1002 (as shown). Figure 18-19 As shown), at this time, the hinge cup 1 continues to close, and the second drive block 1001 continues to rotate counterclockwise and drives the second transmission plate 1002 to compress the second piston rod 10032 to achieve buffering, until the hinge cup 1 is fully closed (as shown). Figure 16-17 As shown), at this time, the second transmission plate 1002 compresses the second piston rod 10032 to the bottom, and at this time, the second protrusion 10013 on the second drive block 1001 rotates to the other end of the second clearance hole 107.

[0063] Therefore, the hinge structure in this embodiment can simultaneously achieve both opening and closing buffering of the hinge cup 1, making it more versatile and applicable to a wider range of situations.

[0064] Example 3 See Figure 20-23 The hinge structure in this embodiment is based on Embodiment 1, with the addition of a third buffer component to buffer the closing of the hinge cup 1. The difference from Embodiment 2 is that the third buffer component in this embodiment is located inside the hinge arm 2 instead of at the hinge cup 1. This third buffer component includes at least a third buffer and a third drive block that drives the third buffer. The third drive block is connected to the rocker arm assembly. When the hinge cup 1 is closed, it simultaneously drives the rocker arm assembly to swing, and the rocker arm assembly drives the third drive block. When the hinge cup 1 is closed to a certain angle, the rocker arm assembly drives the third drive block to move the third buffer, which in turn buffers the hinge cup 1 to achieve the closing buffer.

[0065] Specifically, the third buffer is a third hydraulic cylinder 13, including a third cylinder body 1301 and a third piston rod 1302 movably mounted on the third cylinder body 1301; wherein, when the third piston rod 1302 is driven to extend relative to the third cylinder body 1301, it can generate a buffering effect; the third drive block is a transmission block 14, which is hinged to the hinge arm 2 via a third hinge shaft 16; one end of the transmission block 14 is hinged to the inner rocker arm 4 via a second hinge shaft 15, and the other end of the transmission block 14 is hinged to the third piston rod 1302 via a fourth hinge shaft 17. In addition, the third cylinder body 1301 is hinged to the hinge arm 2 via a fifth hinge shaft 18.

[0066] Therefore, when hinge cup 1 is in the fully open state (e.g.) Figure 20-21 As shown), the third piston rod 1302 is in the retracted state. When it drives the hinge cup 1 to close, it can drive the inner rocker arm 4 to swing until the hinge cup 1 closes to a certain angle (as shown). Figure 22 As shown), the inner rocker arm 4 drives the transmission block 14 to rotate, and the transmission block 14 can drive the third piston rod 1302 to extend to achieve a closing buffer for the hinge cup 1 until the hinge cup 1 is fully closed (as shown). Figure 23 (As shown).

[0067] Therefore, by setting the first buffer component 5 at the hinge cup 1 and the third buffer component inside the hinge arm 2, the hinge structure has both opening and closing buffer functions, which can slow down the opening and closing speed of the cabinet door, avoid cabinet door pinching or collision accidents, and also prevent the cabinet door from violently hitting other objects, thus preventing damage to the cabinet door and hinge structure and extending the service life of the product. In addition, slowing down the opening and closing speed of the cabinet door can also prevent the cabinet door from violently hitting and generating loud noise, thereby creating a quiet environment and improving the user experience.

[0068] Of course, it should be noted that in other embodiments, the third cylinder 13 can also be reversed, and the other end of the transmission block 14 can be hinged to the third cylinder body 1301. The buffer can be achieved by driving the third cylinder body 1301 to extend relative to the third piston rod 1302. The same technical effect can be achieved, and there are no restrictions here.

[0069] Example 4 See Figure 24-27The difference between the hinge structure in this embodiment and that in embodiment three is that the structure of the third buffer component is different. Specifically, the third buffer is a fourth hydraulic cylinder 19, which includes a fourth cylinder body 1901 and a fourth piston rod 1902 movably disposed on the fourth cylinder body 1901. When the fourth piston rod 1902 is driven to compress and move relative to the fourth cylinder body 1901, it can generate a buffering effect. Preferably, the fourth drive block is a sliding seat 20, which is slidably disposed in the hinge arm 2. The sliding seat 20 has an installation groove, and the fourth hydraulic cylinder 19 is placed in the installation groove. The end of the fourth piston rod 1902 abuts against the inner wall of the installation groove, and the fourth cylinder body 1901 protrudes out of the installation groove and abuts and limits the hinge between the outer rocker arm 3 and the hinge arm 2. The sliding seat 20 has a first protrusion 2001, and the inner rocker arm 4 has a second protrusion 402 near the hinge arm 2. The first protrusion 2001 and the second protrusion 402 abut against each other to achieve a transmission connection.

[0070] Therefore, when hinge cup 1 is in the fully open state (e.g.) Figure 24-25 As shown), at this time, the fourth piston rod 1902 is in the extended state. When it drives the hinge cup 1 to close, it can drive the inner rocker arm 4 to swing until the hinge cup 1 closes to a certain angle (such as...). Figure 26 As shown), the inner rocker arm 4 drives the sliding seat 20 to slide and compress the fourth piston rod 1902 to achieve a closing buffer for the hinge cup 1 until the hinge cup 1 is fully closed (as shown). Figure 27 (As shown).

[0071] Preferably, it also includes a torsion spring 21 disposed at the hinge of the outer rocker arm 3 and the hinge arm 2, and the end of the fourth cylinder 1901 abuts against the torsion spring 21 to achieve limiting and fixing.

[0072] Of course, it should be noted that in other embodiments, the fourth cylinder 19 can also be installed in reverse, and the fourth cylinder body 1901 can be compressed by driving the sliding seat 20 to achieve buffering, which can also achieve the same technical effect. This is not a limitation.

[0073] In summary, the hinge structure with opening buffer provided by this utility model has the following beneficial effects: (i) The hinge structure of this utility model, by setting a first buffer component 5 on the hinge cup 1, when the hinge cup 1 is driven to open to a certain angle, the first buffer in the first buffer component 5 can buffer the hinge cup 1, thereby slowing down the opening speed of the cabinet door, thus avoiding damage to the cabinet door and hinge structure due to violent impact, and preventing noise generation; in addition, by slowing down the opening speed of the cabinet door, it can also prevent cabinet door pinching accidents and reduce safety hazards.

[0074] (ii) The hinge structure of this utility model effectively utilizes the external space and avoids the problem of limited internal space by setting the first buffer component 5 outside the groove 101 of the hinge cup 1. In addition, the side of the outer rocker arm 3 is connected to the first drive block 501 through the first drive shaft 6. Thus, when the hinge is fully closed, the first drive shaft 6 will be located on the side of the rocker arm component and will not occupy the depth space of the groove 101. Therefore, there is no need to increase the depth of the groove 101 of the hinge cup 1, so the thickness of the hinge cup 1 can be made thinner, and it can be assembled onto a thinner door panel, making it more versatile.

[0075] (III) The hinge structure of this utility model, by setting the first buffer component 5 and the second buffer component 10 at the hinge cup 1, enables the hinge structure to have both opening buffer and closing buffer functions, thereby slowing down the opening and closing speed of the cabinet door, avoiding pinching or collision accidents, and also preventing the cabinet door from violently hitting other objects, which would damage the cabinet door and hinge structure and extend the service life of the product; in addition, by slowing down the opening and closing speed of the cabinet door, it can also avoid the cabinet door from violently hitting and generating huge noise, thereby creating a quiet environment and improving the user experience.

[0076] (iv) The hinge structure of this utility model effectively utilizes the external space and avoids the problem of limited internal space by setting both the first buffer component 5 and the second buffer component 10 outside the groove 101 of the hinge cup 1. In addition, by setting the first buffer component 5 and the second buffer component 10 on the two outer sides of the groove 101 of the hinge cup 1, the structural layout is more reasonable, the force is more balanced, and it is more compact.

[0077] (v) The hinge structure of this utility model, by setting a first buffer component 5 at the hinge cup 1 and a third buffer component in the hinge arm 2, enables the hinge structure to have both opening buffer and closing buffer functions, thereby slowing down the opening and closing speed of the cabinet door, avoiding cabinet door pinching or collision accidents, and also preventing the cabinet door from violently hitting other objects and causing damage to the cabinet door and hinge structure, thus extending the service life of the product; in addition, by slowing down the opening and closing speed of the cabinet door, it can also avoid the cabinet door from violently hitting and generating huge noise, thereby creating a quiet environment and improving the user experience.
