Description

Technical Field

[0001] This utility model relates to the field of hinge technology, specifically to a hinge structure that simultaneously has opening and closing buffering functions. Background Technology

[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] A hinge is a mechanical device used to connect two fixed parts and allow relative rotation between them. Hinges are divided into ordinary hinges and soft-close hinges. Ordinary hinges do not have a soft-close function, while soft-close hinges are widely used in cabinets because of their better soft-close ability. They are used to cushion the cabinet door when it is closed, preventing the cabinet door from colliding with the cabinet body with excessive force and damaging the cabinet.

[0004] However, existing soft-close hinges do not have a soft-close function. When the cabinet door opens too fast, it can easily pinch children, pets, etc., and when the cabinet door opens too fast and violently hits the cabinet or other obstacles, it can easily damage the cabinet door or hinge structure, resulting in poor product durability. In addition, violent impacts can also generate a lot of noise, reducing the user experience. Utility Model Content

[0005] In order to overcome the defects of the prior art, the present invention provides a hinge structure that has both opening and closing buffering functions, which can solve the problems of insufficient safety, poor durability and poor noise reduction mentioned in the background art.

[0006] The technical solution adopted by this utility model to solve its problem is: A hinge structure that simultaneously provides opening and closing buffering functions includes a hinge cup and a hinge arm, wherein a rocker arm assembly is provided between the hinge cup and the hinge arm to achieve hinged opening and closing, and further includes: A first buffer assembly is disposed on the hinge cup and includes a first buffer and a first drive block that drives and engages with the first buffer. The first drive block is driven and connected to the rocker arm assembly. The second buffer assembly is disposed on the hinge cup and includes a second buffer and a second drive block that drives and cooperates with the second buffer. The second drive block is driven and connected to the rocker arm assembly. Specifically, when the hinge cup is opened or closed, the rocker arm assembly can be driven to swing back and forth simultaneously; when the hinge cup is opened to a certain angle, the rocker arm assembly drives the first drive block to drive the first buffer to move, and the first buffer provides a buffering effect on the hinge cup to achieve opening buffering; when the hinge cup is closed to a certain angle, the rocker arm assembly drives the second drive block to drive the second buffer to move, and the second buffer provides a buffering effect on the hinge cup to achieve closing buffering.

[0007] As an alternative implementation, the hinge cup has a groove configured to accommodate at least a portion of the rocker arm assembly when the hinge cup is closed; the first buffer assembly and the second buffer assembly are respectively located on the two outer sides of the groove.

[0008] As an optional implementation, the rocker arm assembly includes an outer rocker arm, one end of which is hinged to the hinge cup and located within the groove, and the other end of which is hinged to the hinge arm, wherein: Both the first drive block and the second drive block are hinged to the hinge cup and are located on the two outer sides of the groove respectively; one side of one end of the outer rocker arm is connected to the first drive block, and the other side of one end of the outer rocker arm is connected to the second drive block.

[0009] As an optional implementation, it also includes a first drive shaft that passes through the first drive block and is linked with the first drive block. A first clearance hole is provided on one side of the hinge cup, and a first locking hole is provided on one side of one end of the outer rocker arm. The first drive shaft passes through the first clearance hole and is locked and fixed in the first locking hole to realize the transmission connection with the outer rocker arm. When the hinge cup is opened, the outer rocker arm can be driven to swing synchronously. The outer rocker arm is engaged with the first drive shaft and the first locking hole to drive the first drive block to rotate synchronously.

[0010] As an optional implementation, it also includes a second drive shaft that passes through and is linked to the second drive block. A second clearance hole is provided on the other side of the hinge cup, and a second locking hole is provided on the other side of one end of the outer rocker arm. The second drive shaft passes through the second clearance hole and is locked in the second locking hole to realize the transmission connection with the outer rocker arm. The second locking hole can rotate relative to the second drive shaft. When the hinge cup is closed, the outer rocker arm can be driven to swing synchronously. The outer rocker arm rotates relative to the second drive block through the second locking hole until both ends of the second locking hole abut against the second drive shaft, which can drive the second drive block to rotate.

[0011] As an optional implementation, the first buffer includes a first cylinder and a first piston rod movably disposed on the first cylinder. The first buffer assembly also includes a first transmission plate, one end of which is used for transmission connection with the first drive block, and the other end of which is transmitted connection with the first cylinder or the first piston rod. When the hinge cup is opened to a certain angle, the first drive block drives the first cylinder or the first piston rod to extend or retract via the first transmission plate to buffer the hinge cup.

[0012] As an optional implementation, it further includes a first mounting base disposed on one side of the hinge cup and shielding the first buffer assembly, wherein both the first buffer and the first transmission plate are disposed within the first mounting base.

[0013] As an optional implementation, the second buffer includes a second cylinder and a second piston rod movably disposed on the second cylinder. The second buffer assembly also includes a second transmission plate, one end of which is used for transmission connection with the second drive block, and the other end of which is transmitted connection with the second cylinder or the second piston rod. When the hinge cup is closed to a certain angle, the second drive block drives the second cylinder or the second piston rod to extend or retract via the second transmission plate to generate a buffering effect.

[0014] As an optional implementation, a second mounting base is also included, which is disposed on the other side of the hinge cup and shields the second buffer assembly. Both the second buffer and the second transmission plate are disposed within the second mounting base.

[0015] As an optional implementation, it also includes a lever slidably disposed on the hinge cup. The lever has a first position and a second position. When the lever is moved to the first position, the lever separates from the second transmission plate. When the hinge cup is opened, both the second transmission plate and the second buffer can be reset. When the lever is moved to the second position and the hinge cup is opened, the second transmission plate abuts against the lever and is limited, and the second buffer cannot be reset or cannot be fully reset.

[0016] In summary, the hinge structure provided by this utility model, which simultaneously possesses opening and closing buffering functions, has the following beneficial effects: (1) The hinge structure of this utility model, by setting a first buffer component and a second buffer component at the hinge cup, 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 is also possible to avoid the cabinet door from violently hitting and generating huge noise, thereby creating a quiet environment and improving the user experience.

[0017] (2) The hinge structure of this utility model has its first buffer component and second buffer component both set outside the hinge cup groove, thereby effectively utilizing the external space and avoiding the problem of limited internal space; in addition, by setting the first buffer component and the second buffer component separately 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.

[0020] 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.

[0021] 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.

[0022] 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.

[0023] See Figure 1-17 This utility model provides a hinge structure that simultaneously provides opening and closing buffer functions, 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 and a second buffer assembly 7 disposed at the hinge cup 1. The first buffer assembly 5 includes a first buffer 502 and a first drive block 501 that is drivenly engaged with the first buffer 502. The first drive block 501 is drivenly connected to the rocker arm assembly. The second buffer assembly 7 includes a second buffer 702 and a second drive block 701 that is drivenly engaged with the second buffer 702. The second drive block 701 is drivenly connected to the rocker arm assembly.

[0024] When the hinge cup 1 is opened or closed, the rocker arm assembly can be rotated synchronously. The rocker arm assembly can drive the first drive block 501 and the second drive block 701 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 502 to move. The first buffer 502 provides a buffering effect on the hinge cup 1 to achieve opening buffering. When the hinge cup 1 is closed to a certain angle, the rocker arm assembly drives the second drive block 701 to drive the second buffer 702 to move. The second buffer 702 provides a buffering effect on the hinge cup 1 to achieve closing buffering.

[0025] Therefore, by setting the first buffer component 5 and the second buffer component 7 at the hinge cup 1, the hinge structure has both opening and closing buffer functions, which can slow down the opening and closing speed of the cabinet door, avoid 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.

[0026] See Figure 2-3 as well as Figure 5 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; wherein the first buffer assembly 5 and the second buffer assembly 7 are located outside the groove 101. Preferably, the first buffer assembly 5 and the second buffer assembly 7 are located on the two outer sides of the groove 101, respectively. In this way, by arranging the first buffer assembly 5 and the second buffer assembly 7 on the outer side of 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. In addition, by distributing the first buffer assembly 5 and the second buffer assembly 7 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 the structure is more compact.

[0027] The rocker arm assembly includes an outer rocker arm 3, one end of which is hinged to a hinge cup 1 and located in a groove 101, and the other end of which is hinged to a hinge arm 2. The first drive block 501 and the second drive block 701 are both hinged to the hinge cup 1 and are located on the two outer sides of the groove 101 respectively. One side of one end of the outer rocker arm 3 is connected to the first drive block 501, and the other side of one end of the outer rocker arm 3 is connected to the second drive block 701. See also Figure 2-3 Specifically, it also includes a first drive shaft 5012 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 locking hole 302 is provided on one side of one end of the outer rocker arm 3. The first drive shaft 5012 passes through the first clearance hole 102 and is locked and fixed within the first locking hole 302 to achieve a transmission connection with the outer rocker arm 3. Thus, when the hinge cup 1 is opened, the outer rocker arm 3 can be driven to swing synchronously. The outer rocker arm 3, through the locking engagement of the first drive shaft 5012 and the first locking hole 302, synchronously drives the first drive block 501 to rotate.

[0028] Additionally, it includes a second drive shaft 7012 that passes through and is linked to the second drive block 701. A second clearance hole 106 is provided on the other side of the hinge cup 1, and a second locking hole 303 is provided on the other side of one end of the outer rocker arm 3. The second drive shaft 7012 passes through the second clearance hole 106 and is engaged in the second locking hole 303 to achieve a transmission connection with the outer rocker arm 3. The second locking hole 303 can rotate relative to the second drive shaft 7012. Therefore, 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 701 through the second locking hole 303 until both ends of the second locking hole 303 abut against the second drive shaft 7012, at which point it can drive the second drive block 701 to rotate.

[0029] In this embodiment, the outer rocker arm 3 has a fourth hinge hole 301 on both sides near the hinge cup 1, the first drive block 501 has a sixth hinge hole 5013, the second drive block 701 has a seventh hinge hole 7013, and the two side walls of the groove 101 of the hinge cup 1 have a first hinge hole 103. Thus, by passing the first hinge shaft 10 through the two fourth hinge holes 301, the two first hinge holes 103, the sixth hinge hole 5013, and the seventh hinge hole 7013 respectively, the two sides of one end of the outer rocker arm 3, the first drive block 501, and the second drive block 701 can all be hinged to the hinge cup 1.

[0030] See also Figure 2-3 The first buffer 502 is a first hydraulic cylinder including a first cylinder body 5021 and a first piston rod 5022 movably mounted on the first cylinder body 5021. The first buffer assembly 5 also includes a first transmission plate 503, one end of which is connected to the first drive block 501, and the other end of which is connected to either the first cylinder body 5021 or the first piston rod 5022. When the hinge cup 1 is opened to a certain angle, the first drive block 501, through the first transmission plate 503, drives the first cylinder body 5021 or the first piston rod 5022 to extend or retract, thereby providing a buffering effect on the hinge cup 1.

[0031] In this embodiment, when the first piston rod 5022 is compressed and moved relative to the first cylinder 5021, it can generate a buffering effect; preferably, one end of the first transmission plate 503 is provided with a first protrusion 5031, and the first drive block 501 is provided with a first protrusion 5011. The first protrusion 5031 is used to abut against the first protrusion 5011 to achieve a transmission connection; the other end of the first transmission plate 503 is bent with a first bend 5032, and the first bend 5032 is used to abut against the first piston rod 5022 to achieve a transmission connection.

[0032] Therefore, when the hinge cup 1 is opened to a certain angle, the first protrusion 5011 on the first drive block 501 can abut against the first protrusion 5031 on the first transmission plate 503, and then drive the first transmission plate 503 to move. The first bent portion 5032 on the first transmission plate 503 can abut against and compress the first piston rod 5022 to produce a buffering effect on 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 503, and the first piston rod 5022 extends and resets, driving the first transmission plate 503 to reset and move until the first piston rod 5022 is fully reset.

[0033] Of course, it should be noted that in other embodiments, the first buffer 502 can also be reversed and the first cylinder 5021 can be compressed by the first transmission plate 503 to produce a buffering effect on the hinge cup 1, which can also achieve the same technical effect. This is not a limitation.

[0034] Furthermore, the hinge structure also includes a first mounting base 6 disposed on the side of the hinge cup 1 and shielding the first buffer assembly 5. The first buffer 502 and the first transmission plate 503 are both disposed within the first mounting base 6. One end of the first mounting base 6 has two first hooks 604 arranged vertically at intervals. The hinge cup 1 has two corresponding first mounting holes 107. By engaging the two first hooks 604 into the two first mounting holes 107, one end of the first mounting base 6 can be fixed in a limited position. The other end of the first mounting base 6 has a first limiting hole 603. Both sides of the groove 101 of the hinge cup 1 have third hinge holes 105. By using second pins 902 to pass through the first limiting hole 603 and the third hinge holes 105 respectively, the other end of the first mounting base 6 can be fixed in a limited position, thereby assembling and fixing the first mounting base 6 onto the hinge cup 1.

[0035] The first mounting base 6 has a first mounting groove 601 that matches the shape of the first cylinder 5021 and a second mounting groove 602 that matches the shape of the first transmission plate 503. The first buffer 502 is placed in the first mounting groove 601 and the first transmission plate 503 is placed in the second mounting groove 602. When the first mounting base 6 is assembled and fixed on the hinge cup 1, it can limit and fix the first buffer 502 and the first transmission plate 503.

[0036] See also Figure 2-3The second buffer 702 is a second hydraulic cylinder and includes a second cylinder body 7021 and a second piston rod 7022 movably mounted on the second cylinder body 7021. The second buffer assembly 7 also includes a second transmission plate 703. One end of the second transmission plate 703 is used for transmission connection with the second drive block 701, and the other end of the second transmission plate 703 is transmitted connection with the second cylinder body 7021 or the second piston rod 7022. When the hinge cup 1 is closed to a certain angle, the second drive block 701, through the second transmission plate 703, drives the second cylinder body 7021 to extend or retract, or the second piston rod 7022 to extend or retract, thereby providing a buffering effect on the hinge cup 1.

[0037] In this embodiment, when the second piston rod 7022 is compressed and moved relative to the second cylinder 7021, it can generate a buffering effect; preferably, one end of the second transmission plate 703 is provided with a second protrusion 7031, and the second drive block 701 is provided with a second protrusion 7011. The second protrusion 7031 is used to abut against the second protrusion 7011 to achieve a transmission connection; the other end of the second transmission plate 703 is bent with a second bend 7032, and the second bend 7032 is used to abut against the second piston rod 7022 to achieve a transmission connection.

[0038] Therefore, when the hinge cup 1 is closed to a certain angle, the second protrusion 7011 on the second drive block 701 can abut against the second protrusion 7031 on the second transmission plate 703, thereby driving the second transmission plate 703 to move. The second bent portion 7032 on the second transmission plate 703 can abut against and compress the second piston rod 7022 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 701 through the second locking hole 303. The second piston rod 7022 extends and resets, simultaneously driving the second transmission plate 703 and the second drive block 701 to reset. Subsequently, the outer rocker arm 3 abuts against the second drive block 701 through the second locking hole 303 to drive the second drive block 701 to reset and rotate.

[0039] Of course, it should be noted that in other embodiments, the second buffer 702 can also be reversed and the second cylinder 7021 can be compressed by the second transmission plate 703 to produce a buffering effect on the hinge cup 1, which can also achieve the same technical effect, and is not limited here.

[0040] Furthermore, the hinge structure also includes a second mounting base 8 disposed on the other side of the hinge cup 1 and covering the second buffer assembly 7. The second buffer 702 and the second transmission plate 703 are both disposed within the second mounting base 8. One end of the second mounting base 8 has two second hooks 804 arranged vertically at intervals. The hinge cup 1 has two corresponding second mounting holes 108. By engaging the two second hooks 804 into the two second mounting holes 108, one end of the second mounting base 8 can be fixed in a limited position. The other end of the second mounting base 8 has a second limiting hole 803. The second pin 902 passes through the second limiting hole 803 and the third hinge hole 105 respectively, thus fixing the other end of the second mounting base 8 in a limited position, thereby assembling and fixing the second mounting base 8 onto the hinge cup 1.

[0041] The second mounting base 8 has a third mounting groove 801 that matches the shape of the second cylinder 7021 and a fourth mounting groove 802 that matches the shape of the second transmission plate 703. The second buffer 702 is placed in the third mounting groove 801 and the second transmission plate 703 is placed in the fourth mounting groove 802. When the second mounting base 8 is assembled and fixed on the hinge cup 1, it can limit and fix the second buffer 702 and the second transmission plate 703.

[0042] See also Figure 2-3 The 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 end of the inner rocker arm 4 near the hinge cup 1 is bent to form a fifth hinge hole 401. The two side walls of the groove 101 of the hinge cup 1 are provided with second hinge holes 104. Thus, by using the first pin 901 to pass through the two second hinge holes 104 and the fifth hinge hole 401 respectively, one end of the inner rocker arm 4 can be hinged to the hinge cup 1.

[0043] In this embodiment, the first pin 901 and the second pin 902 are integrally formed to create a double pin 9.

[0044] The hinge structure in this embodiment works as follows: When hinge cup 1 is in the fully closed state (e.g.) Figure 8-9 As shown), at this time, the first protrusion 5011 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 synchronously drives the first drive block 501 to rotate counterclockwise until the first protrusion 5011 on the first drive block 501 abuts against the first protrusion 5031 of the first transmission plate 503 (as shown). Figure 10-11As shown), the hinge cup 1 continues to open, and the first drive block 501 continues to rotate counterclockwise, driving the first transmission plate 503 to compress the first piston rod 5022 to achieve buffering, until the hinge cup 1 is fully open (as shown). Figure 6-7 As shown), at this time, the first transmission plate 503 compresses the first piston rod 5022 to the bottom, and the first protrusion 5011 on the first drive block 501 rotates to the other end of the first clearance hole 102.

[0045] When hinge cup 1 is in the fully open state (e.g.) Figure 12-13 As shown), at this time, the second protrusion 7011 on the second drive block 701 is located at one end of the second clearance hole 106. 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 701 to rotate counterclockwise until the second protrusion 7011 on the second drive block 701 abuts against the second protrusion 7031 of the second transmission plate 703 (as shown). Figure 16-17 As shown), at this time, the hinge cup 1 continues to close, and the second drive block 701 continues to rotate counterclockwise and drive the second transmission plate 703 to compress the second piston rod 7022 to achieve buffering, until the hinge cup 1 is fully closed (as shown). Figure 14-15 As shown), at this time, the second transmission plate 703 compresses the second piston rod 7022 to the bottom, and at this time, the second protrusion 7011 on the second drive block 701 rotates to the other end of the second clearance hole 106.

[0046] In addition, the hinge structure also includes a lever 11 slidably disposed on the hinge cup 1, the lever 11 having a first position and a second position; preferably, the lever 11 includes a lever body 1101, a lever portion 1102 disposed on the top of the lever body 1101, and a protruding rod portion 1103 disposed on the bottom of the lever body 1101. The lever portion 1102 extends out of the hinge cup 1 to facilitate user movement, and the protruding rod portion 1103 is used to abut against the second transmission plate 703; thus, when the lever 11 is moved to the first position, the lever 11... The protruding rod portion 1103 separates from the second transmission plate 703. When the hinge cup 1 is opened, both the second transmission plate 703 and the second buffer 702 can be reset. When the toggle block 11 is moved to the second position and the hinge cup 1 is closed, under the closing force of the hinge, the second transmission plate 703 can abut against the protruding rod portion 1103 and pass over the protruding rod portion 1103 to compress the second piston rod 7022. When the hinge cup 1 is opened, the second transmission plate 703 abuts against the protruding rod portion 1103 again and is limited. The second buffer 702 cannot be reset or cannot be fully reset.

[0047] Therefore, by setting the toggle block 11, the closing buffer stroke of the hinge structure can be controlled or whether the hinge structure has a closing buffer function can be controlled, thereby enabling the hinge structure to have more working modes and adapt to different usage scenarios.

[0048] In summary, the hinge structure provided by this utility model, which simultaneously possesses opening and closing buffering functions, has the following beneficial effects: (i) The hinge structure of this utility model, by setting a first buffer component 5 and a second buffer component 7 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 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 can also avoid the cabinet door from violently hitting and generating huge noise, thereby creating a quiet environment and improving the user experience.

[0049] (ii) The hinge structure of this utility model has its first buffer component 5 and second buffer component 7 both located outside the groove 101 of the hinge cup 1, thereby effectively utilizing the external space and avoiding the problem of limited internal space; in addition, by setting the first buffer component 5 and the second buffer component 7 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.
