Description

Technical Field

[0001] This invention relates to the field of hinge technology, and further to a novel synchronous transmission front damping hinge. Background Technology

[0002] Damping hinges, as a key mechanical transmission component, are widely used in buildings, vehicles, bridges, and industrial equipment. Their core function is to suppress structural vibrations, reduce impact noise, and improve the smoothness and comfort of opening and closing doors through damping. Currently, damping hinges on the market are mainly divided into segmented compression-driven damping hinges and single-piece rolled-circle-driven damping hinges. Segmented compression-driven damping hinges achieve their damping effect through a segmented structure, relying on the spring inside the damper automatically rebounding to its initial damping state after the door is opened. While this design provides a certain level of damping performance, it suffers from complex structures, demanding assembly processes, and high costs. Furthermore, segmented structures are prone to gaps between components under dynamic loads, leading to uneven damping force or abnormal noise. Single-piece rolled-circle-driven damping hinges use a single-piece stamped rolled-circle transmission component, simplifying the structure and reducing manufacturing costs. However, limited by the precision of traditional stamping processes, it is difficult to achieve a standard circular structure for the rolled-circle transmission component, resulting in unstable rotation and a tendency to bounce during door closing. This vibration can not only cause abnormal noises, but may also accelerate hinge wear and reduce its service life.

[0003] Therefore, there is an urgent need to develop a new type of synchronous transmission front damping hinge to solve the technical problems in the existing technology. Summary of the Invention

[0004] To address the aforementioned technical problems, the present invention aims to provide a novel synchronous transmission front-damped hinge that can solve the problems mentioned in the background section.

[0005] To achieve the above objectives, the present invention provides a novel synchronous transmission front-damped hinge, comprising a cup head and an arm body, and further comprising:

[0006] A damper rubber component is disposed on one end of the arm body corresponding to the end near the cup head. A damping hole is formed on the damper rubber component, and a damper is disposed in the damping hole.

[0007] A stacked sheet conveying assembly is used to connect the cup head and the damper rubber part. The stacked sheet conveying assembly includes two stacked sheet edge pieces, which are arranged in parallel, and multiple stacked sheet pieces are arranged between the two stacked sheet edge pieces. The multiple stacked sheet pieces are arranged in pairs in parallel and close to each other.

[0008] A damper drive component is disposed on the damper rubber component and correspondingly abuts against the damper.

[0009] A two-hole transmission component is used to drive the damper transmission component and the laminated plate transmission assembly. When the hinge is closed, the laminated plate transmission assembly rotates and pushes the damper towards the cup head through the damper transmission component, so that the hinge slows down the closing speed under the resistance of the damper.

[0010] In some embodiments, the arm body includes a quick-release movable plate and a straight arm body, the straight arm body being sleeved on the quick-release movable plate, and the damper rubber component being hinged and fixed to the quick-release movable plate and the straight arm body.

[0011] In some embodiments, the novel synchronous transmission pre-damped hinge provided in this application further includes:

[0012] The plum blossom-shaped component has one end connected to the cup head via a forked wire component, and the other end rotatably connected to the straight arm body via a first rotating shaft.

[0013] In some embodiments, a spring member rotates on the first rotating shaft, and the spring member extends with two abutting members. The two abutting members extend along the length direction of the plum blossom member and the length direction of the straight arm body, respectively, and abut against the plum blossom member and the straight arm body.

[0014] In some embodiments, the damper rubber component has a first rotating groove and a first abutting groove on one end corresponding to the end near the laminated component;

[0015] The laminated edge piece has a first transmission hole and a first connecting hole at one end near the damper rubber piece. A first transmission shaft is provided through the first transmission hole and is rotatably disposed in the first rotation groove. A first connecting member is provided through the first connecting hole and is disposed in the first abutment groove when the hinge is in the open state.

[0016] In some embodiments, a mounting groove is provided at the bottom of the damping hole, and the mounting groove matches the damper.

[0017] In some embodiments, sliding grooves are provided on both sides of the damper component along the direction of movement of the damper.

[0018] The damper transmission component is a U-shaped component, which includes two sides and an abutting edge between the two sides. The two sides are slidably disposed in two sliding grooves, and the abutting edge abuts against the damper.

[0019] In some embodiments, sliding grooves are provided on both sides of the damper component along the direction of movement of the damper.

[0020] The damper transmission component is a U-shaped component, which includes two sides and an abutting edge between the two sides. The two sides are slidably disposed in two sliding grooves, and the abutting edge abuts against the damper.

[0021] Compared with the prior art, the novel synchronous transmission front damping hinge provided by the present invention has the following beneficial effects:

[0022] 1. The novel synchronous transmission front damping hinge provided by the present invention, through the linkage design of setting two-hole transmission components, stacked plate conveying components, and damper transmission components, ensures that the components move synchronously during the transmission process, realizes a synchronous transmission structure, reduces rotational runout, and further improves rotational stability. In addition, the stacked plate conveying component is composed of two stacked plate edge components and multiple stacked plate components in the middle, avoiding the abnormal noise caused by local protrusions or depressions in traditional single-plate rolling.

[0023] 2. The novel synchronous transmission front damping hinge provided by the present invention sets the damping hole on the damper rubber part to match the shape of the damper, and the mounting groove restricts the radial displacement of the damper; the U-shaped damper transmission component slides with the damper rubber part through the sliding groove to ensure that the damper moves only along the axial direction and avoids uneven wear.

[0024] 3. The novel synchronous transmission front damping hinge provided by the present invention provides elastic buffering for the damping structure through the abutment members in both directions by setting spring members, generating self-locking force, so that the door can be closed when the hinge is closed to about 45°, and in combination with the resistance of the damper, the closing speed can be adaptively adjusted.

[0025] 4. The novel synchronous transmission front-mounted damping hinge provided by this invention shortens the force transmission path between the damper and the cup head by placing the damper in front, reducing energy loss during transmission, while providing rapid response and precise synchronous transmission control, achieving a smooth, stable, and quiet closing throughout the entire process.

[0026] 5. The novel synchronous transmission front-mounted damping hinge provided by the present invention effectively shortens the longitudinal dimension of the hinge by slidingly fitting the damper rubber part and the damper transmission part together, thereby saving installation space, simplifying the structure and reducing costs.

For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0037] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0038] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0039] In one embodiment, refer to the appendix to the specification. Figure 1-4 The present invention provides a novel synchronous transmission front-damped hinge, which includes not only a cup head 20 and an arm body 30, but also: a damper rubber component 40, a laminate conveying assembly 10, a damper transmission component 50, and a two-hole transmission component 60. The damper rubber component 40 is disposed on the arm body 30 at an end corresponding to the cup head 20, and has a damping hole in it, within which a damper is disposed. The laminate conveying assembly 10 connects the cup head 20 and the damper rubber component 40, and includes two laminate edge components 11. Two stacked edge pieces 11 are arranged in parallel, and multiple stacked pieces 12 are arranged between the two stacked edge pieces 11. The multiple stacked pieces 12 are arranged in pairs in parallel and close to each other. The damper transmission piece 50 is arranged on the damper rubber piece 40 and abuts against the damper. The two-hole transmission piece 60 is used to drive the damper transmission piece 50 and the stacked piece transmission assembly. When the hinge is closed, the stacked piece transmission assembly rotates and pushes the damper towards the cup head 20 through the damper transmission piece 50, so that the hinge slows down the closing speed under the resistance of the damper.

[0040] Specifically, the damper rubber part 40 is fixed to one end of the arm body 30 near the cup head 20, and the damping hole opened on it provides a precise positioning space for the installation and fixing of the damper, ensuring that the damper is coaxially aligned with the subsequent transmission components. The damper is typically a viscous or elastic damping structure. The laminated conveyor assembly 10 serves as a power transmission intermediate connecting the cup head 20 and the damper rubber part 40. The laminated conveyor assembly 10 adopts a sandwich structure of double laminated edge pieces 11 + multiple laminated pieces 12. The two parallel laminated edge pieces 11 act as a frame, and the multiple laminated pieces 12 sandwiched in the middle are parallel and tightly fitted in pairs. This design effectively increases the contact area and disperses stress, uniformly transmitting the torque of the cup head 20 when it rotates to the end of the damper rubber part 40. When the cup head 20 rotates under external force, the laminated edge pieces 11 rotate synchronously with the cup head 20. The friction between the laminated pieces 12 converts the rotational tendency into linear thrust, which is ultimately transmitted to the damper drive component 50. The damper drive component 50 directly abuts against the damper, and its function is to convert the linear thrust of the laminated conveyor assembly 10 into resistance against the damper. The damper's squeezing action effectively avoids abnormal noise. The two-hole transmission component 60 is a connecting plate or rod with two mounting holes. It is fixed and rigidly connected to the damper transmission component 50 and the laminated plate transmission assembly 10 respectively through the mounting holes at both ends, forming a complete transmission chain of cup head 20 rotation, laminated plate assembly force transmission, two-hole component linkage, and damper transmission component 50 pushing the damper. This ensures the synchronicity and stability of force transmission from cup head 20 to damper. Through the synergistic force of multiple laminated plates and the symmetrical constraint of the two-hole component, the off-center load or lag in the transmission process is effectively avoided, so that the hinge movement remains smooth at any opening and closing angle. In addition, the multi-parallel laminated plate design of the laminated plate transmission assembly 10 replaces the traditional single-point contact with surface contact. Multiple parallel and closely attached laminated plates 12 share the load, disperse stress, and significantly improve the rigidity and deformation resistance of the transmission components.

[0041] It should be noted that the damper rubber component 40 is made of a highly elastic rubber material. The deformation characteristics of the rubber material help absorb the impact, thereby providing a stable support interface for the damper and avoiding displacement deviation caused by vibration. The material of the damper rubber component 40 can be high-elasticity rubber, engineering plastic, or any other rubber material. There are no restrictions here.

[0042] In one embodiment, refer to the appendix to the specification. Figure 1 and 2 Based on the above embodiments, the arm body 30 includes a quick-release movable plate 32 and a straight arm body 31. The straight arm body 31 is sleeved on the quick-release movable plate 32, and the damper rubber part 40 is hinged and fixed on the quick-release movable plate 32 and the straight arm body 31.

[0043] Specifically, the arm body 30 serves as the main load-bearing component of the hinge, with the straight arm body 31 acting as its basic structure. Typically made of cold-rolled steel or aluminum alloy profiles, its core function is to provide stable support for the quick-release sliding piece 32 and subsequent components. The quick-release sliding piece 32 is primarily used for rapid assembly, improving assembly efficiency. The straight arm body 31 has guide grooves, and the quick-release sliding piece 32 has raised edges. These two elements work together to ensure the linear movement trajectory of the door panel during opening and closing, avoiding problems caused by installation errors in traditional hinges. Simultaneously, the double hinge structure of the damper rubber component 40 with the quick-release sliding piece 32 and the straight arm body 31 further strengthens the connection strength of the damper rubber component 40.

[0044] In one embodiment, refer to the appendix to the specification. Figure 1 , 2 In addition to the above embodiments, the novel synchronous transmission front damping hinge provided by the present invention also includes a plum blossom component 70. One end of the plum blossom component 70 is connected to the cup head 20 through a fork wire component, and the other end of the plum blossom component 70 is rotatably connected to the straight arm body 31 through a first rotating shaft.

[0045] Specifically, the plum blossom component 70 serves as the power conversion hub. One end is flexibly connected to the cup head 20 via the fork connector, and the other end is rigidly connected to the straight arm body 31 via the first rotating shaft. This allows the opening and closing trajectory of the door leaf to be purified into a rotational motion around a fixed axis via the first rotating shaft, effectively ensuring the smooth and seamless movement of the hinge.

[0046] In one embodiment, refer to the appendix to the specification. Figure 1 , 2 4. A spring 90 rotates on the first rotating shaft. The spring 90 extends and is provided with two abutting parts 91. The two abutting parts 91 extend along the length direction of the plum blossom part 70 and the length direction of the straight arm body 31, respectively, and abut against the plum blossom part 70 and the straight arm body 31.

[0047] Specifically, the first rotating shaft is typically a cylindrical metal shaft, with its diameter precisely matched to the inner diameter of the spring element 90 to ensure that the spring element 90 can rotate freely around the shaft without loosening. The spring element 90 employs a double torsion spring structure, with the main body of the double torsion spring structure tightly fitted onto the first rotating shaft. Two abutment members 91 extend from each end of the double torsion spring structure, extending vertically upwards along the axial length of the plum blossom element 70. These abutment members 91 are vertically upward-facing sheet-like structures that contact the lower end face of the plum blossom element 70. When the plum blossom element 70 rotates, its axial displacement compresses the abutment member 91, causing the spring element 90 to undergo compressive deformation, thereby generating a reverse elastic force to limit excessive rotation of the plum blossom element. The outer part contacts the inner end face of the straight arm body 31. When the straight arm body 31 is laterally displaced due to the opening and closing of the door panel, the abutment 91 will be pushed, causing the spring 90 to undergo shear deformation. The movement speed of the straight arm body 31 is adjusted through elastic feedback. By setting the double abutment 91 of the spring 90, the hinge can automatically return to the initial position when there is no external force, that is, automatically close the door at 45°. The double abutment 91 of the spring 90 will be continuously pressed due to the displacement of the plum blossom part and the straight arm body 31. The elastic potential energy is gradually released, generating resistance in the opposite direction of movement, causing the door panel to decelerate to close at a low speed, effectively avoiding the collision between the door panel and the cabinet, thereby reducing noise and significantly improving the user experience.

[0048] In one embodiment, refer to the appendix to the specification. Figure 1 and 4 Based on the above embodiments, a first rotating groove 42 and a first abutting groove are provided on the damper rubber part 40 corresponding to the end near the stacked part 12;

[0049] The laminated edge piece 11 has a first transmission hole and a first connecting hole at one end near the damper rubber piece 40. A first transmission shaft 111 is provided through the first transmission hole and is rotatably disposed in the first rotation groove 42. A first connector 112 is provided through the first connecting hole and is disposed in the first abutment groove when the hinge is in the open state.

[0050] Specifically, the end face of the damper rubber part 40 that contacts the lamination conveying assembly 10 is provided with a first rotating groove 42 and a first abutting groove. The first abutting groove typically has a crescent-shaped side profile, and its axis is parallel to the rotation direction of the lamination conveying assembly 10. The depth and diameter of the groove need to be clearance-fitted with the outer diameter of the first drive shaft 111 to ensure that the first drive shaft 111 can rotate freely in the groove without radial offset. The first abutting groove is a hemispherical groove that matches the shape of the first connector 112, and its opening direction is consistent with the hinge opening direction. The depth of the groove is adapted to the first connector 112 to ensure that the first connector 112 can be partially embedded in the groove when the hinge is open, providing a pre-positioning force. The end face of the laminated plate that contacts the damper rubber part 40 is provided with a first transmission hole and a first connecting hole. The first transmission hole is a through hole with its axis coinciding with the axis of the first rotating groove 42 and its diameter is slightly larger than the outer diameter of the first transmission shaft 111. The first connecting hole is a through hole with its axis coinciding with the axis of the first abutment groove and its diameter precisely matches the outer diameter of the first connector 112, ensuring that the first connector 112 can only move axially in the hole. The cooperation between the first transmission shaft 111 and the first rotating groove 42 effectively reduces torque fluctuation and friction during the opening / closing process of the hinge, making the overall movement smoother, reducing noise and improving user comfort. In addition, the fitting design of the first connector 112 and the first abutment groove provides a limiting effect when the hinge is open: to avoid rigid collision or detachment when the hinge rotates too much.

[0051] In one embodiment, refer to the appendix to the specification. Figure 1 and 4 Based on the above embodiments, a mounting groove 41 is provided at the bottom of the damping hole, and the mounting groove 41 matches the damper 80.

[0052] Specifically, the damping hole is opened at one end of the damper rubber part 40 near the laminate part 12. It is a cylindrical hole with a mounting groove 41 extending from the bottom. The size of the mounting groove 41 is precisely matched with the shape of the damper 80, and forms an axial limit with the top edge of the mounting groove 41. This achieves the effect of preventing the damper 80 from falling out of the damping hole under vibration or impact, and also reduces the generation of noise to a certain extent, further improving the reliability of this application.

[0053] In one embodiment, refer to the appendix to the specification. Figure 1 and 4 Based on the above embodiments, sliding grooves 43 are provided on both sides of the damper rubber part 40 along the moving direction of the damper 80.

[0054] The damper transmission component 50 is a U-shaped component, which includes two sides and an abutting edge between the two sides. The two sides are slidably disposed in two sliding grooves 43, and the abutting edge abuts against the damper 80.

[0055] Specifically, the damper rubber component 40 has two symmetrical sliding grooves 43 on both sides along the moving direction of the damper 80. The sliding grooves 43 are both long straight grooves, which are opened on both sides of the end face of the damper rubber component 40 that contacts the damper 80, so that the two sides of the U-shaped component can slide. The symmetrical constraint of the double sliding grooves 43 and the sliding cooperation of the U-shaped component further improve the smoothness and fluidity of the transmission process.

[0056] In one embodiment, refer to the appendix to the specification. Figure 1 and 3 Based on the above embodiments, multiple stacked pieces 12 are stamped and stacked together to form an integrated structure.

[0057] Specifically, the laminated piece 12 is usually made of cold-rolled steel plate or stainless steel. The interference fit or partial welding design of the integrated laminated piece 12 eliminates the gap between traditional laminated pieces 12, avoids the laminated piece 12 from loosening or falling off due to vibration or impact, and thus enhances the synchronization effect of transmission.

[0058] The working principle of this invention is as follows: When the door panel is close to closing, the hinge enters the buffer stage. As the straight arm body 31 continues to move in the closing direction, the stacked edge piece 11 of the stacked piece conveying assembly rotates further. The torque is amplified and transmitted to the damper transmission piece 50 through the friction between the stacked pieces 12. The two sides of the damper transmission piece 50 slide along the sliding groove 43 of the damper rubber piece 40. Its abutting edge continuously squeezes the damper 80, causing the damper 80 to generate resistance in the opposite direction of movement, hindering the damper rubber piece 40 from moving towards the cup head 20, thereby limiting the speed of the door panel. At the same time, the high elasticity material of the damper rubber piece 40 absorbs vibration energy and reduces noise during the transmission process. When the door panel is close to being fully closed, the elastic potential energy of the spring piece 90 is released, causing the door to automatically enter the closed state. At the same time, the first connecting piece 112 is re-embedded into the first abutting groove of the damper rubber piece.

[0059] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
