Description

Technical Field

[0001] This utility model belongs to the technical field of hinge accessories, specifically relating to a hinge cup and a buffer hinge on which a buffer mechanism can be installed. Background Technology

[0002] In current soft-close hinge designs, the buffering mechanism is typically built into the hinge arm, relying on a series of complex connectors to link the four-bar linkage to the buffer. When the hinge is closed by an external force, the movement of the four-bar linkage is transmitted to the buffer through these connectors, causing the internal piston mechanism to stretch or compress linearly, using hydraulic oil to generate a buffering effect. However, this design has significant limitations: the complex connection transitions can not only lead to distortion in motion trajectory transmission, but also often cause problems such as uneven buffering speed, jamming, unsmooth feel, and door panel impact.

[0003] Furthermore, since the buffer is integrated with the hinge into an inseparable whole through fixing methods such as riveting, in certain specific application scenarios, users may want to remove the buffer function to achieve undamped closing, but the existing design cannot meet this flexible switching requirement.

[0004] To address the aforementioned issues, it is hypothetical that a new buffer hinge structure could be designed, in which the buffer mechanism is directly mounted on the hinge cup, thereby circumventing the problems. Utility Model Content

[0005] The purpose of this invention is to overcome a series of problems caused by the installation of the buffer mechanism inside the hinge arm in existing buffer hinges, and to provide a hinge cup on which the buffer mechanism can be installed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution.

[0007] A hinge cup with a buffer mechanism is provided, including a hinge cup body. The hinge cup body is provided with a buffer mounting part, a base clearance part and a hinge arm connecting part from front to back. The inner side of the base clearance part and the hinge arm connecting part is a groove, and the base clearance part communicates with the hinge arm connecting part. The hinge arm connecting part is provided with a clearance opening that passes through its rear.

[0008] This invention features a hinge cup with a buffer mounting section. The buffer mechanism can be directly mounted on the hinge cup and is located on the front side of the hinge cup. The buffer mechanism only contacts the hinge arm when the hinge cup is about to enter a fully closed state from an open state, or in the initial stage of opening from a closed state, thus exerting a buffering effect. When the hinge is fully open, the buffer mechanism remains separate from the hinge arm, ensuring that they do not interfere with each other. Compared with the prior art, this invention not only simplifies the hinge connection mechanism and improves the hinge's simplicity and stability, but also achieves precise synchronization between the buffer mechanism and the hinge cup's movement trajectory by directly mounting the buffer mechanism on the hinge cup, eliminating the need for any intermediate transmission links and thus eliminating the problem of decreased buffering performance caused by transmission distortion. Furthermore, the physical separation of the buffer mechanism from the hinge arm body forms an independent system. This design ensures that the damping mechanism only activates during specific stages requiring buffering, while operating completely independently at other times. This not only improves the hinge's service life but also provides users with a smoother, non-jamming opening and closing experience. It should be noted that when the hinge cup of this utility model is in the folded state, the base clearance portion covers the outside of the base, and the space inside forms the receiving space at the front of the base. The base of this utility model refers to the part of the buffer hinge that is fixed to the cabinet.

[0009] To facilitate assembly, the buffer mounting part includes a buffer mounting groove.

[0010] Furthermore, the hinge arm connection portion has connecting holes on both sides, with at least three sets of connecting holes, and at least one set of connecting holes has a flanged boss on its outer periphery. This design uses flanged bosses to increase the contact area between the connecting holes and the mounting pins. In actual assembly, the hinge arm is rotatably connected to the mounting pins via the mounting holes. The mounting pins pass through the connecting holes. The hinge can use segmented U-shaped pins to connect the hinge arm and the hinge cup. The segmented U-shaped pin is U-shaped overall, with an asymmetrical structure where one side is a long side and the other a short side. The connecting holes with flanged bosses are used to connect to the short side of the U-shaped pin. Simultaneously, the hinge arm mechanism generally includes a first hinge arm and a second hinge arm. One side of the hinge arm connects to two connecting holes on the same side, and the long side extends to the other side, connecting to the connecting hole on the other side. Thus, each U-shaped pin requires three connecting holes. Increasing the mounting contact area of ​​the short side of the segmented U-shaped pin prevents uneven force distribution due to unequal lengths on both sides, which could lead to excessive force on the short side and insufficient contact area, potentially causing it to detach.

[0011] Furthermore, it also includes a hinge cup cover adapted to the shape of the hinge cup body. The hinge cup cover is disposed on the hinge cup body and has a buffer receiving groove corresponding to the buffer mounting groove. An axial receiving space is formed between the buffer mounting groove and the buffer receiving groove. The hinge cup cover has a clearance opening on the side near the hinge arm connection part. In this solution, the hinge cup cover is used to cooperate with the hinge cup body to restrict the buffer mechanism on the hinge cup. At the same time, the hinge cup cover has a clearance opening so that after the buffer mechanism is installed on the hinge cup, the connecting mechanism of the buffer mechanism can cooperate with the hinge arm mechanism through the clearance opening to realize the buffer function.

[0012] Furthermore, the buffer mounting portion also includes a guide portion, which is located on one side of the buffer mounting portion and protrudes upward along the buffer mounting groove.

[0013] Furthermore, the hinge cup body has a pull-block mounting groove on the outer side of the base clearance portion, and the hinge cup cover has a pull-block adjustment port corresponding to the pull-block mounting groove. The pull-block mounting groove in this solution is used to install the limiting pull-block of the buffer mechanism. In actual use, the limiting pull-block is movably disposed within the pull-block mounting groove, and it has at least a first position and a second position. When it is in the first position, its fixed end engages with the buffer mechanism to restrict the movement of the buffer mechanism. When it is in the second position, it separates from the buffer mechanism, allowing the buffer mechanism to be unrestricted. The limiting pull-block has a pull-block driving part, which protrudes from the hinge cup cover through the pull-block adjustment port, allowing the user to move the pull-block by moving the pull-block driving part back and forth. Compared with the prior art, this solution meets the user's need for undamped closure under specific circumstances.

[0014] Furthermore, the pull-out block limiting structure includes a toothed limiting boss, which is disposed on the side wall of the pull-out block mounting groove. The pull-out block limiting structure of this solution is used to cooperate with the structure on the limiting pull-out block to achieve a limiting function, ensuring that the limiting pull-out block remains in its moved position after it has been moved into place.

[0015] Furthermore, a guide surface is provided on one side of the guide portion, and the guide surface is designed as a helical curved surface. In actual design, the buffer mechanism is provided with a matching helical guide groove corresponding to the guide portion. When the buffer mechanism is subjected to forward pressure, it rotates axially, and the helical guide portion cooperates with the top pressure portion of the buffer mechanism, so that the buffer mechanism moves linearly while rotating, thereby achieving helical motion.

[0016] Another objective of this invention is to provide a buffer hinge, comprising a base, a hinge cup, a hinge arm mechanism, and a buffer mechanism. The base is connected to the hinge cup via the hinge arm mechanism. The buffer mechanism is movably mounted on the hinge cup and has a buffer pressing part. When the hinge is in the closed state, the buffer pressing part abuts against the hinge arm mechanism; when the buffer hinge is in the open state, the buffer pressing part separates from the hinge arm mechanism. Compared with the prior art, the buffer hinge of this invention, due to the application of the aforementioned hinge cup, possesses all the advantages of the above-mentioned solutions.

[0017] Furthermore, the hinge mechanism includes a first hinge arm and a second hinge arm. One end of the first hinge arm and the second hinge arm are respectively connected to the base, and the other end is respectively hinged to the hinge cup, so that the base, the first hinge arm, the hinge cup and the second hinge arm form a swingable four-bar linkage mechanism. The buffer mechanism is disposed on the base, and its movable end is linked to the hinge mechanism.

[0018] Furthermore, the buffer mechanism is a hydraulic cylinder, which is arranged laterally on the buffer mounting part. The handle of its piston abuts against the side wall of the hinge cup. The other end of its cylinder body away from the piston is provided with a top pressing part that matches the guide part. After the buffer mechanism is compressed, the buffer mechanism rotates under force. The spiral top pressing part cooperates with the top pressing part to drive the cylinder body to move to the other side, thereby compressing the entire buffer mechanism. Attached Figure Description

Detailed Implementation

[0034] The specific embodiments of this utility model are described below with reference to the accompanying drawings. In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0035] Example 1:

[0036] See Figure 9-12 As shown, this embodiment discloses a hinge cup on which a buffer mechanism 6 can be installed, including a hinge cup body 2. The hinge cup body 2 is provided with a buffer mounting part 21, a base clearance part 22 and a hinge arm connecting part 23 in sequence from front to back. The inner sides of the base clearance part 22 and the hinge arm connecting part 23 are grooves, and the base clearance part 22 communicates with the hinge arm connecting part 23. The hinge arm connecting part 23 is provided with a clearance passage 231 that passes through its rear.

[0037] For ease of assembly, the buffer mounting part 21 includes a buffer mounting groove 211.

[0038] The hinge arm connecting part 23 has connecting holes 232 on both sides. There are at least three sets of connecting holes 232, and at least one set of connecting holes 232 has a flanged boss 233 on its outer periphery. The flanged boss 233 is designed to increase the contact area between the connecting hole 232 and the mounting pin. During actual assembly, the hinge arm is rotatably connected to the mounting pin through the mounting hole. The mounting pin passes through the connecting hole 232. The hinge can be connected to the hinge cup using a segmented U-shaped pin. The segmented U-shaped pin is U-shaped overall and has an asymmetrical structure with one side being a long side and the other a short side. The connecting hole 232 with the flanged boss 233 is used to connect to the short side of the U-shaped pin. Simultaneously, the hinge arm mechanism 5 generally includes a first hinge arm and a second hinge arm. One side of the hinge arm connects to two connecting holes 232 on the same side, and the long side extends to the other side, connecting to the connecting hole 232 on the other side. Thus, each U-shaped pin requires three connecting holes 232. Increase the installation contact area of ​​the short side of the segmented U-shaped pin to prevent uneven force distribution due to different lengths on both sides, which could lead to greater force on the short side and less contact area, thus posing a risk of detachment.

[0039] Furthermore, it also includes a hinge cup cover 25 adapted to the shape of the hinge cup body 2. The hinge cup cover 25 is placed on the hinge cup body 2 and has a buffer receiving groove 252 corresponding to the buffer mounting groove 211. An axial receiving space is formed between the buffer mounting groove 211 and the buffer receiving groove 252. The hinge cup cover 25 has a clearance opening 253 on the side near the hinge arm connecting part 23. In this solution, the hinge cup cover 25 is used to cooperate with the hinge cup body 2 to restrict the buffer mechanism 6 on the hinge cup. At the same time, the hinge cup cover 25 has a clearance opening 253 so that after the buffer mechanism 6 is installed on the hinge cup, the connecting mechanism of the buffer mechanism 6 can cooperate with the hinge arm mechanism 5 through the clearance opening 253 to realize the buffer function.

[0040] For ease of assembly, the hinge cup cover 25 is fastened to the hinge cup body 2 via a fastening structure 26. The fastening structure 26 includes an inverted buckle 261 on the hinge cup cover 25 and a fastening groove 262 on the hinge cup body 2.

[0041] The hinge cup body 2 has a pull-block mounting groove 24 on the outer side of the base clearance portion 22, and the hinge cup cover 25 has a pull-block adjustment port 251 corresponding to the pull-block mounting groove 24. In this design, the pull-block mounting groove 24 is used to install the limiting pull-block of the buffer mechanism 6. In actual use, the limiting pull-block 62 is movably disposed within the pull-block mounting groove 24, and it has at least a first position and a second position. When it is in the first position, its fixed end engages with the buffer mechanism 6 to restrict the movement of the buffer mechanism 6. When it is in the second position, it separates from the buffer mechanism 6, allowing the buffer mechanism 6 to be unrestricted. The limiting pull-block 62 has a pull-block driving part, which protrudes from the hinge cup cover 25 through the pull-block adjustment port 251, allowing the user to move the pull-block by moving the pull-block driving part back and forth. Compared with the prior art, this design meets the user's need for undamped closure under specific circumstances.

[0042] The aforementioned block limiting structure includes a toothed limiting boss 241, which is disposed on the side wall of the block mounting groove 24. This block limiting structure cooperates with the structure on the limiting block 62 to achieve a limiting effect, ensuring that the limiting block 62 remains in its moved position after it has been moved into place.

[0043] The aforementioned buffer mounting portion 21 further includes a guide portion 212, which is located on one side of the buffer mounting portion 21 and protrudes upward along the buffer mounting groove 211.

[0044] The guide portion 212 described above has a guide surface on one side, which is designed as a helical curved surface. When the buffer mechanism 6 is subjected to forward pressure, it rotates axially. The helical guide portion 212 cooperates with the top pressure portion of the buffer mechanism 6, causing the buffer mechanism 6 to move linearly while rotating, thus achieving a helical motion.

[0045] Furthermore, the guide portion 212 is provided with a limiting step 213 on the side near the middle of the buffer mounting groove 211. The limiting step 213 is used to cooperate with the limiting structure on the buffer mechanism 6, so that the buffer mechanism 6 stops moving after resetting, thus avoiding excessive displacement.

[0046] In this embodiment, the hinge cup is provided with a buffer mounting part 21. The buffer mechanism 6 can be directly mounted on the hinge cup of the hinge and is located on the front side of the hinge cup. The buffer mechanism 6 only contacts the hinge arm when the hinge cup is about to enter the fully closed state from the open state, or in the initial stage of opening from the closed state, thereby playing a buffering role. In the fully open state of the hinge, the buffer mechanism 6 remains separated from the hinge arm to ensure that the two do not interfere with each other. Compared with the prior art, this utility model not only simplifies the connection mechanism of the hinge and improves the simplicity and stability of the hinge; but also achieves precise synchronization between the movement trajectory of the buffer mechanism 6 and the hinge cup by directly mounting the buffer mechanism 6 on the hinge cup, without any intermediate transmission links, thereby eliminating the problem of decreased buffering performance caused by transmission distortion. In addition, the physical separation of the buffer mechanism 6 from the hinge arm body forms an independent system. This design allows the damping mechanism to be activated only in specific stages where buffering is needed, while operating completely independently at other times. This not only improves the service life of the hinge, but also brings users a smoother, non-jamming opening and closing experience.

[0047] Example 2:

[0048] See Figure 1-13 As shown, this embodiment discloses a buffer hinge 1, including a base 4, a hinge cup, a hinge arm mechanism 5, and a buffer mechanism 6. The base 4 is connected to the hinge cup via the hinge arm mechanism 5. The buffer mechanism 6 is movably mounted on the hinge cup and has a buffer pressing part 61. When the hinge is in the closed state, the buffer pressing part 61 abuts against the hinge arm mechanism 5. When the buffer hinge 1 is in the open state, the buffer pressing part 61 separates from the hinge arm mechanism 5. Compared with the prior art, the buffer hinge 1 of this utility model has all the advantages of the above-mentioned solution because it uses the aforementioned hinge cup.

[0049] The aforementioned hinge mechanism 5 includes a first hinge arm 51 and a second hinge arm 52. One end of the first hinge arm 51 and the second hinge arm 52 are respectively connected to the base 4, and the other end is respectively hinged to the hinge cup, so that the base 4, the first hinge arm 51, the hinge cup and the second hinge arm 52 form a swingable four-bar linkage mechanism. The buffer mechanism 6 is disposed on the base 4, and its movable end is linked to the hinge mechanism 5.

[0050] The aforementioned buffer mechanism 6 is a hydraulic cylinder, which is arranged laterally on the buffer mounting part 21. The handle of its piston abuts against the side wall of the hinge cup. The other end of its cylinder body away from the piston is provided with a top pressing part that is adapted to the guide part 212. After the buffer mechanism 6 is compressed, the buffer mechanism 6 rotates under force. The spiral top pressing part cooperates with the top pressing part to drive the cylinder body to move to the other side, thereby compressing the buffer mechanism 6 as a whole.

[0051] The aforementioned pull-out mounting slot 24 is slidably provided with a limiting pull-out block 62, and the buffer mechanism 6 is provided with a limiting groove adapted to the limiting pull-out block 62. The limiting pull-out block 62 and the limiting groove can be connected by plugging and unplugging.
