Description

Technical Field

[0001] This utility model relates to the field of hinge technology, specifically to a novel double-buffered hinge. 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 quickly, they can easily pinch children, pets, etc., resulting in low safety and protection. In addition, when the cabinet door opens too quickly and violently impacts the cabinet or other obstacles, it can easily damage the cabinet door or hinge structure, resulting in poor product durability. Furthermore, violent impacts can generate a lot of noise, resulting in poor noise reduction. Utility Model Content

[0005] In order to overcome the defects mentioned in the prior art, the present invention provides a novel double-buffered hinge, which can solve the problems of insufficient safety and protection, poor durability and quietness mentioned in the background art.

[0006] The technical solution adopted by this utility model to solve its problem is: A novel double-buffered hinge includes a hinge cup and a hinge arm. A rocker arm assembly is provided between the hinge cup and the hinge arm to achieve hinged opening and closing. The rocker arm assembly includes an outer rocker arm and an inner rocker arm. One end of the outer rocker arm and one end of the inner rocker arm are hinged to the hinge cup, and the other ends of the outer rocker arm and the other end of the inner rocker arm are hinged to the hinge arm. The hinge also includes: A first buffer assembly is disposed within the hinge arm and includes a first buffer and a first drive block that drives and engages with the first buffer.

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 drivenly connected to one end of the outer rocker arm near the hinge cup. Specifically, when the hinge cup is opened or closed, the outer rocker arm and the inner rocker arm can be driven to swing back and forth simultaneously; when the hinge cup is opened to a certain angle, the inner rocker arm 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 outer rocker arm 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 optional implementation, the first drive block is slidably disposed inside the hinge arm; the first drive block is provided with a first protrusion, and the inner rocker arm is provided with a second protrusion at one end near the hinge arm, the second protrusion being used to abut against the first protrusion to achieve a transmission connection; When the hinge cup is opened, the inner rocker arm can be swung simultaneously. When the hinge cup is opened to a certain angle, the second protrusion on the inner rocker arm abuts against the first protrusion of the first drive block and drives the first drive block to slide relative to the hinge arm.

[0008] As an optional implementation, the first buffer is a first hydraulic cylinder, and includes a first cylinder body and a first piston rod movably disposed on the first cylinder body; The first drive block has an installation groove, and the first cylinder is disposed in the installation groove; wherein, one of the first cylinder body and the first piston rod abuts against the inner wall of the installation groove to achieve a transmission connection, and the other part of the first cylinder body and the first piston rod protrudes out of the installation groove and is limited; When the hinge cup is opened to a certain angle, the first drive block compresses the first piston rod to provide a buffering effect on the hinge cup.

[0009] As an optional implementation, it also includes a fixed shaft passing through the hinge arm, with the first cylinder or the first piston rod abutting against the fixed shaft to achieve a limiting action.

[0010] 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 second buffer assembly is located outside the groove.

[0011] As an optional implementation, the second drive block is hinged to the hinge cup and located on the outer side of the groove; the side of the outer rocker arm near the hinge cup is connected to the second drive block in a transmission manner.

[0012] As an optional implementation, it also includes a drive shaft that passes through the two drive blocks and is linked with the second drive block. A clearance hole is provided on one side of the hinge cup, and a locking hole is provided on the side of the outer rocker arm near one end of the hinge cup. The drive shaft passes through the clearance hole and is locked in the locking hole to realize the transmission connection with the outer rocker arm. When the hinge cup is closed, the outer rocker arm can be swung synchronously, and the outer rocker arm drives the second drive block to rotate synchronously.

[0013] As an optional implementation, the second buffer is a second hydraulic cylinder, and includes a second cylinder body and a second piston rod movably disposed on the second cylinder body; the second buffer assembly also includes a transmission plate, one end of which is used for transmission connection with the second drive block, and the other end of which is transmission connection with the second cylinder body 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 transmission plate to buffer the hinge cup.

[0014] As an optional implementation, the second drive block is provided with a third protrusion, and one end of the transmission plate is provided with a fourth protrusion for abutting and engaging with the third protrusion to achieve a transmission connection; the other end of the transmission plate is bent to form a bent portion, and the bent portion abuts against the second cylinder or the second piston rod to achieve a transmission connection.

[0015] As an optional implementation, it also includes a mounting base disposed on the hinge cup and used to shield the second buffer assembly, wherein both the second buffer and the transmission plate are disposed within the mounting base.

[0016] In summary, the novel double-buffered hinge provided by this utility model has the following beneficial effects: (1) The double buffer hinge of this utility model, by setting a first buffer component in the hinge arm and a second buffer component on the hinge cup, enables the hinge 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 improving safety and protection; at the same time, it can also prevent the cabinet door from violently hitting other objects, causing damage to the cabinet door and hinge structure, extending the service life of the product, and improving the durability of the product; in addition, by slowing down the opening and closing speed of the cabinet door, it can also prevent the cabinet door from violently hitting and generating huge noise, thereby creating a quiet environment, improving the user experience, and improving the quietness of the product.

[0017] (2) The double buffer hinge of this utility model effectively utilizes the external space and avoids the problem of limited internal space by setting the second buffer component outside the hinge cup groove. Attached Figure Description

Detailed Implementation

[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 1-15 This utility model provides a novel double-buffered hinge, including a hinge cup 1 fixed to a 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. The rocker arm assembly includes an outer rocker arm 3 and an inner rocker arm 4. One end of the outer rocker arm 3 and one end of the inner rocker arm 4 are hinged to the hinge cup 1, and the other end of the outer rocker arm 3 and the other end of the inner rocker arm 4 are hinged to the hinge arm 2. Therefore, when the hinge cup 1 is opened or closed, the outer rocker arm 3 and the inner rocker arm 4 can be simultaneously driven to swing back and forth. In addition, it also includes a first buffer assembly 5 and a second buffer assembly 7. The first buffer assembly 5 is disposed inside the hinge arm 2 and includes a first buffer and a first drive block 501 that is driven to cooperate with the first buffer. The first drive block 501 is driven to be connected to one end of the inner rocker arm 4 near the hinge arm 2. The second buffer assembly 7 is disposed on the hinge cup 1 and includes a second buffer and a second drive block 701 that is driven to cooperate with the second buffer. The second drive block 701 is driven to be connected to one end of the outer rocker arm 3 near the hinge cup 1.

[0024] When the hinge cup 1 is opened or closed, the outer rocker arm 3 and the inner rocker arm 4 can swing back and forth simultaneously. The inner rocker arm 4 can drive the first drive block 501 to move. When the hinge cup 1 is opened to a certain angle, the inner rocker arm 4 drives the first drive block 501 to drive the first buffer to move. The first buffer provides a buffering effect on the hinge cup 1 to achieve opening buffering. The outer rocker arm 3 can drive the second drive block 701 to move. When the hinge cup 1 is closed to a certain angle, the outer rocker arm 3 drives the second drive block 701 to drive the second buffer to move. The second buffer provides a buffering effect on the hinge cup 1 to achieve closing buffering.

[0025] Therefore, by setting the first buffer component 5 inside the hinge arm 2 and the second buffer component 7 on the hinge cup 1, the hinge simultaneously possesses opening and closing buffer functions. This slows down the opening and closing speed of the cabinet door, preventing door pinching or collision accidents and improving safety and protection. Simultaneously, it prevents the cabinet door from violently impacting other objects, thus avoiding damage to the cabinet door and hinge structure, extending the product's lifespan and improving its durability. Furthermore, slowing down the opening and closing speed of the cabinet door also prevents violent impacts that could generate significant noise, creating a quiet environment, improving the user experience, and enhancing the product's quietness.

[0026] See Figure 2-6 Specifically, the first drive block 501 is slidably disposed inside the hinge arm 2; a first protrusion 5011 is provided on both sides of the bottom of one end of the first drive block 501, and a second protrusion 401 is provided on both sides of the inner rocker arm 4 near the hinge arm 2. The second protrusion 401 is used to abut against the first protrusion 5011 to achieve a transmission connection; thus, when the hinge cup 1 is driven to open, the inner rocker arm 4 can be driven to swing synchronously; when the hinge cup 1 is driven to open to a certain angle, the second protrusion 401 on the inner rocker arm 4 abuts against the first protrusion 5011 of the first drive block 501 and drives the first drive block 501 to slide relative to the hinge arm 2.

[0027] More specifically, the first buffer is a first hydraulic cylinder 502, and includes a first cylinder body 5021 and a first piston rod 5022 movably disposed on the first cylinder body 5021; the first drive block 501 has a mounting groove 5012, and the first hydraulic cylinder 502 is disposed in the mounting groove 5012. The first piston rod 5022 abuts against the inner wall of the mounting groove 5012 to achieve a transmission connection, and the first cylinder body 5021 protrudes from the mounting groove 5012 and is limited in position.

[0028] Therefore, when the hinge cup 1 is opened to a certain angle, the first drive block 501 compresses the first piston rod 5022 to produce a buffering effect on the hinge cup 1.

[0029] In this embodiment, a fixed shaft 6 is also provided inside the hinge arm 2, and the first cylinder 5021 abuts against the fixed shaft 6 to achieve a limiting position.

[0030] Of course, it should be noted that in other embodiments, the first cylinder 502 can also be installed in reverse, that is, the first cylinder body 5021 abuts against the inner wall of the mounting groove 5012 of the first drive block 501, and the first piston rod 5022 extends out of the mounting groove 5012 and is limited; thus, the first cylinder body 5021 is compressed by the first drive block 501 to produce a buffering effect on the hinge cup 1, which can also achieve the same technical effect, and is not limited here.

[0031] Therefore, the opening process of the double-buffered hinge in this embodiment is as follows: When hinge cup 1 is in a fully closed state (e.g.) Figure 6 As shown), at this time, the first piston rod 5022 is in the extended state. When it drives the hinge cup 1 to open, it can drive the inner rocker arm 4 to swing until the hinge cup 1 is opened to a certain angle. At this time, the second protrusion 401 of the inner rocker arm 4 abuts against the first protrusion 5011 on the first drive block 501 to realize transmission (as shown). Figure 5 As shown), when the hinge cup 1 continues to open, the inner rocker arm 4 drives the first drive block 501 to slide relative to the hinge arm 2 and compress the first piston rod 5022 to achieve a buffering effect on the hinge cup 1, until the hinge cup 1 is fully opened (as shown). Figure 3-4 (As shown).

[0032] See Figure 7-15 The hinge cup 1 has a groove 101 configured to accommodate at least a portion of the rocker arm assembly when the hinge cup 1 is closed; the second buffer assembly 7 is located outside the groove 101. Thus, by placing the second buffer assembly 7 outside the groove 101 of the hinge cup 1, the external space is effectively utilized, avoiding the problem of limited internal space.

[0033] The second drive block 701 is hinged to the hinge cup 1 and located on the outer side of the groove 101. The side of the outer rocker arm 3 near the hinge cup 1 is connected to the second drive block 701. Additionally, a drive shaft 7012 passes through and is linked to the second drive block 701. A clearance hole 102 is provided on one side of the hinge cup 1, and a locking hole 301 is provided on the side of the outer rocker arm 3 near the hinge cup 1. The drive shaft 7012 passes through the clearance hole 102 and is locked in the locking hole 301 to achieve a transmission connection with the outer rocker arm 3. Therefore, when the hinge cup 1 is closed, the outer rocker arm 3 is simultaneously driven to swing, and the outer rocker arm 3 drives the second drive block 701 to rotate synchronously.

[0034] In this embodiment, the outer rocker arm 3 has a fourth hinge hole 302 on both sides near the hinge cup 1, the second drive block 701 has a sixth 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 9 through the two fourth hinge holes 302, the two first hinge holes 103, and the sixth hinge hole 7013 respectively, the outer rocker arm 3 can be hinged to the hinge cup 1 on both sides.

[0035] More specifically, the second buffer is a second hydraulic cylinder 703, and includes a second cylinder body 7031 and a second piston rod 7032 movably disposed on the second cylinder body 7031; the second buffer assembly also includes a transmission plate 702, one end of which is used for transmission connection with the second drive block 701, and the other end of which is transmission connection with the second piston rod 7032. When the hinge cup 1 is closed to a certain angle, the second drive block 701 drives the second piston rod 7032 to extend and retract through the transmission plate 702 to generate a buffering effect on the hinge cup 1.

[0036] In this embodiment, when the second piston rod 7032 is compressed and moved relative to the second cylinder 7031, it can generate a buffering effect; preferably, the second drive block 701 is provided with a third protrusion 7011, and one end of the transmission plate 702 is provided with a fourth protrusion 7021 for abutting and cooperating with the third protrusion 7011 to realize the transmission connection; the other end of the transmission plate 702 is bent to form a bent portion 7022, and the bent portion 7022 abuts with the second piston rod 7032 to realize the transmission connection.

[0037] Therefore, when the hinge cup 1 is closed to a certain angle, the third protrusion 7011 on the second drive block 701 can abut against the fourth protrusion 7021 on the transmission plate 702, and then drive the transmission plate 702 to move. The bent part 7022 of the transmission plate 702 can abut against and compress the second piston rod 7032 to produce a buffering effect on 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 and the second drive block 701 can be driven to rotate and reset simultaneously. The second drive block 701 disengages from the transmission plate 702, and the second piston rod 7032 extends and resets, driving the transmission plate 702 to reset and move until the second piston rod 7032 is completely reset.

[0038] Of course, it should be noted that in other embodiments, the second cylinder 703 can also be installed in reverse, and the second cylinder body 7031 can be compressed by the transmission plate 702 to produce a buffering effect on the hinge cup 1, which can also achieve the same technical effect, and is not limited here.

[0039] Furthermore, it also includes a mounting base 8 disposed on the side of the hinge cup 1 and covering the second buffer assembly 7. The second hydraulic cylinder 703 and the transmission plate 702 are both disposed within the mounting base 8. One end of the mounting base 8 has two hooks 804 arranged vertically at intervals. The mounting base 8 is engaged with the hinge cup 1 by the two hooks 804 to achieve a limiting and fixing effect on one end. The other end of the mounting base 8 has a limiting hole 803. Both sides of the groove 101 of the hinge cup 1 have third hinge holes 105. A second pin 1002 is inserted through the limiting hole 803 and the two third hinge holes 105 respectively to achieve a limiting and fixing effect on the other end of the mounting base 8.

[0040] The mounting base 8 has a first mounting groove 801 that matches the shape of the second cylinder 7031 and a second mounting groove 802 that matches the shape of the transmission plate 702. The second cylinder 7031 is placed in the first mounting groove 801 and the transmission plate 702 is placed in the second mounting groove 802. When the mounting base 8 is assembled and fixed on the hinge cup 1, it can limit and fix the second buffer and the transmission plate 702.

[0041] In addition, a fifth hinge hole 402 is formed on one end of the inner rocker arm 4 near the hinge cup 1. The two side walls of the groove 101 of the hinge cup 1 are provided with second hinge holes 104. Thus, by passing the first pin 1001 through the two second hinge holes 104 and the fifth hinge hole 402 respectively, one end of the inner rocker arm 4 can be hinged to the hinge cup 1.

[0042] In this embodiment, the first pin 1001 and the second pin 1002 are integrally formed to form a double pin 10.

[0043] Therefore, the closing process of the hinge in this embodiment is as follows: When hinge cup 1 is in the fully open state (e.g.) Figure 10-11 As shown), at this time, the third protrusion 7011 on the second drive block 701 is located at one end of the clearance hole 102. When the hinge cup 1 is closed, the outer rocker arm 3 can be rotated synchronously. The outer rocker arm 3 synchronously drives the second drive block 701 to rotate counterclockwise until the third protrusion 7011 on the second drive block 701 abuts against the fourth protrusion 7021 of the transmission plate 702 (as shown). Figure 12-13 As shown), the hinge cup 1 continues to close, and the second drive block 701 continues to rotate counterclockwise, driving the transmission plate 702 to compress the second piston rod 7032 to achieve buffering, until the hinge cup 1 is completely closed (as shown). Figure 14-15 As shown), at this time, the transmission plate 702 compresses the second piston rod 7032 to the bottom, and the third protrusion 7011 on the second drive block 701 rotates to the other end of the clearance hole 102.

[0044] In summary, the novel double-buffered hinge provided by this utility model has the following beneficial effects: (I) The double-buffered hinge of this utility model, by setting a first buffer component 5 in the hinge arm 2 and a second buffer component 7 on the hinge cup 1, enables the hinge to have both opening and closing buffer functions, thereby slowing down the opening and closing speed of the cabinet door, avoiding cabinet door pinching or collision accidents, and improving safety and protection; at the same time, it can also prevent the cabinet door from violently hitting other objects, causing damage to the cabinet door and hinge structure, extending the service life of the product, and improving the durability of the product; in addition, by slowing down the opening and closing speed of the cabinet door, it can also prevent the cabinet door from violently hitting and generating huge noise, thereby creating a quiet environment, improving the user experience, and improving the quietness of the product.

[0045] (ii) The double buffer hinge of this utility model effectively utilizes the external space and avoids the problem of limited internal space by setting the second buffer component 7 outside the groove 101 of the hinge cup 1.

[0046] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on the other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to the other component.

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.
