Description
Technical Field
[0001] This utility model relates to the field of hinges, and more particularly to a concealed, three-dimensionally adjustable, bidirectional damping hinge device. Background Technology
[0002] Top and bottom hinges are a key hardware component widely used in furniture such as cabinets and wardrobes, as well as interior doors in buildings. Their core function is to enable smooth opening and closing and precise positioning of doors. Traditional top and bottom hinges typically have basic rotation functions, while some products also integrate dampers for soft closing or add simple adjustment mechanisms to compensate for installation errors. While these hinges meet basic usage requirements, there is still considerable room for improvement in their performance and user experience.
[0003] However, existing hinges of this type still have several obvious shortcomings in practical applications. First, in terms of damping performance, most products only provide unidirectional buffering at the closing end, failing to effectively solve the problem of door vibration and shaking caused by inertia in the initial closing phase. Furthermore, they are still prone to colliding with the cabinet at the final closing moment, generating noise. Second, regarding adjustment functions, existing hinges often only allow for limited one- or two-dimensional adjustments, making it difficult to simultaneously and conveniently calibrate the door's depth, width, and height independently and precisely. This causes inconvenience for installation, debugging, and later maintenance, and makes it difficult to compensate for misalignment between the door panel and the cabinet caused by processing or deformation. These problems collectively affect the overall quality of the furniture, its noise reduction effect, and its lifespan. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a concealed, three-dimensionally adjustable, bi-directional damping hinge device that achieves a gentle, smooth, and quiet closing effect, improving user experience and product quality, ensuring uniform door gaps and tight closure, and greatly enhancing installation adaptability and reliability.
[0005] To achieve the above objectives, the present invention provides the following technical solution: A concealed, three-dimensionally adjustable, and bidirectionally damped top and bottom hinge device includes a shell consisting of a main shell and a mounting shell, a movable cup holder, a movable plate consisting of a front movable plate and a rear movable plate, and an inner rocker arm and an outer rocker arm connecting the movable plate (i.e., the front movable plate and the rear movable plate) and the movable cup holder. A first adjustment mechanism and a second adjustment mechanism are provided between the shell and the movable plate, an elastic mechanism is provided between the adjustment seat and the movable plate, and a damping mechanism is provided between the inner rocker arm and the movable plate. A third adjustment mechanism is provided inside the movable cup holder. One end of the inner rocker arm and the outer rocker arm is rotatably connected to the movable plate, and the other end is rotatably connected to a fixed plate. During the closing process, the damping mechanism applies force to both ends of the damper sequentially to prevent the door from vibrating or shaking in the initial stage of closing and to prevent the door from colliding with the counter and producing noise in the later stage of closing.
[0006] Furthermore, the damping mechanism includes a front moving plate and a rear moving plate, an inner rocker arm, a damper, and a damping block. In the initial stage of door closing, at approximately 45 degrees, the middle pressing block at one end of the inner rocker arm first contacts the damping sleeve at one end of the damper. In the middle stage of door closing, at approximately 25 degrees, the outer pushing block at the other end of the inner rocker arm contacts the upper blocking block at one end of the damping block, causing the lower blocking block at the other end of the damping block to contact the damping rod at the other end of the damper. The damper is acted on simultaneously in both directions.
[0007] Furthermore, the first adjustment mechanism includes a main body shell, a mounting shell, an adjustment seat, and a first adjustment screw. The adjustment seat includes an upper slider, a side mounting block, and a lower slider that mates with the first upper sliding groove, the first mounting groove, the first lower sliding groove, the second upper sliding groove, the second mounting groove, and the second lower sliding groove of the main body shell and the mounting shell, respectively. The head of the first adjustment screw mates with the first adjustment groove and the second adjustment groove of the mounting shell. By adjusting the first adjustment screw, the adjustment seat can move back and forth relative to the shell.
[0008] Furthermore, the second adjustment mechanism includes a front moving plate, a rear moving plate, an adjustment seat, a traction inclined block, and a second adjustment screw.
[0009] Furthermore, the third adjustment mechanism includes a movable cup holder, a third adjustment screw, a force-bearing inclined block, a slider, and a pad.
[0010] Furthermore, the elastic mechanism includes an outer rocker arm, a spring, and a guide shaft.
[0011] This utility model has the following beneficial effects: 1. In this utility model, by setting a unique bidirectional damping mechanism, the damper is applied twice in different stages of the closing process, at approximately 45° in the initial stage and approximately 25° in the final stage. This design can effectively absorb the kinetic energy of the door leaf, completely avoiding the vibration and shaking caused by the door being too fast in the initial stage of closing, as well as the noise generated by the violent collision with the cabinet in the final stage of closing. Ultimately, a gentle, smooth, and quiet closing effect is achieved, improving the user experience and product quality.
[0012] 2. In this utility model, the independently set first adjustment mechanism, second adjustment mechanism and third adjustment mechanism realize the independent and precise adjustment of the door body in the depth (front and back), width (left and right) and height directions respectively. This design allows installers or users to easily correct and compensate for the assembly error between the door panel and the cabinet or the deformation caused by long-term use on site, ensuring that the door gap is uniform and the closure is tight, which greatly improves the installation adaptability and the reliability of use.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Reference Figure 1-3 This utility model provides an embodiment of a concealed, three-dimensionally adjustable, bidirectional damped hinge device, comprising a shell consisting of a main shell 1 and a mounting shell 2, a movable cup holder 5, a movable plate consisting of a front movable plate 6 and a rear movable plate 14, and an inner rocker arm 4 and an outer rocker arm 3 connecting the movable plate (i.e., the front movable plate 6 and the rear movable plate 14) and the movable cup holder 5. A first adjustment mechanism and a second adjustment mechanism are provided between the shells 1 and 2 and the movable plates 6 and 14, and an elastic mechanism is provided between the adjustment seat 7 and the movable plates 6 and 14. A damping mechanism is provided between the rocker arm 4 and the moving plates 6 and 14. A third adjustment mechanism is provided inside the movable cup holder 5. One end of the inner rocker arm 4 and the outer rocker arm 3 are rotatably connected to the moving plates 6 and 14, and the other end is rotatably connected to the fixed plate 19. During the closing process, the damping mechanism applies force to both ends of the damper 21 sequentially to prevent the door from vibrating or shaking in the initial stage of closing, and to prevent the door from colliding with the counter and producing noise in the later stage of closing. The damping mechanism includes the front moving plate 6 and the rear moving plate 14, the inner rocker arm 4, the damper 21, and the damping block 10. (Refer to...) Figure 9 and Figure 10In the initial stage of closing, within approximately 45 degrees, the middle pressure block 4.1 at one end of the rocker arm 4 first contacts the damping sleeve 21.1 at one end of the damper 21, as shown in the reference. Figure 8 When the door is closed, at approximately 25 degrees, the other end of the rocker arm 4 pushes outward, and the upper block 10.1 at one end of the damping block 10 abuts against the lower block 10.2 at the other end of the damping block 10, which then abuts against the damping rod 21.2 at the other end of the damper 21. The damper 21 is acted on simultaneously in both directions. The elastic mechanism includes the outer rocker arm 3, the spring 9, and the guide shaft 20. When the door is closed to about 45°, the middle pressure block 4.1 at one end of the inner rocker arm 4 first contacts and compresses the damping sleeve 21.1 at one end of the damper 21, providing initial resistance and effectively preventing the door from vibrating or shaking due to excessive speed in the initial closing stage. When the door continues to close to about 25°, the outer push block 4.2 at the other end of the inner rocker arm 4 pushes the upper block 10.1 at one end of the damping block 10, which in turn drives the lower block 10.2 at the other end to contact and compress the damping rod 21.2 of the damper 21, forming secondary resistance, thereby preventing the door from colliding with the cabinet and generating noise at the end of the closing stage.
[0017] Reference Figure 2 , Figure 3 and Figure 4 The first adjustment mechanism includes a main body shell 1, a mounting shell 2, an adjustment seat 7, and a first adjustment screw 11. The adjustment seat 7 includes an upper slider 7.1, a side mounting block 7.2, and a lower slider 7.3, which cooperate with the first upper sliding groove 1.2, the first mounting groove 1.3, the first lower sliding groove 1.4, the second upper sliding groove 2.2, the second mounting groove 2.3, and the second lower sliding groove 2.4 respectively included in the mounting shell 2 of the main body shell 1. The head of the first adjustment screw 11 cooperates with the first adjustment groove 1.1 and the second adjustment groove 2.1 of the mounting shell 2 of the main body shell 1. By adjusting the first adjustment screw 11, the adjustment seat 7 can move back and forth relative to the shells 1 and 2. The second adjustment mechanism includes a front moving plate 6, a rear moving plate 14, an adjustment seat 7, a traction inclined block 8, and a second adjustment screw 12. The third adjustment mechanism includes a movable cup seat 5, a third adjustment screw 13, a force-bearing inclined block 16, a slider 15, and a pad 18. Rotating the first adjusting screw 11 drives the adjusting seat 7, which in turn drives the upper slider 7.1 and lower slider 7.3 to slide back and forth along the first upper sliding groove 1.2, the first lower sliding groove 1.4, the second upper sliding groove 2.2, and the second lower sliding groove 2.4 on the main body shell 1 and the mounting shell 2. This causes the connected moving plates 6 and 14 and the door to move back and forth synchronously, thus adjusting the front and rear positions of the door. Rotating the second adjusting screw 12 drives the traction inclined block 8 to move, pushing the front and rear moving plates 6 and 14 to move left and right, thus finely adjusting the left and right positions of the door. Rotating the third adjusting screw 13 installed on the movable cup holder 5 pushes the force-bearing inclined block 16 and the slider 15, thereby adjusting the height of the movable cup holder 5 and adjusting the vertical direction of the door.
[0018] Working principle: When the door is closed to about 45°, the middle pressure block 4.1 at one end of the inner rocker arm 4 first contacts and compresses the damping sleeve 21.1 at one end of the damper 21, providing initial resistance and effectively preventing the door from vibrating or shaking due to excessive speed in the initial closing stage. When the door continues to close to about 25°, the outer push block 4.2 at the other end of the inner rocker arm 4 pushes the upper block 10.1 at one end of the damping block 10, which in turn drives the lower block 10.2 at the other end to contact and compress the damping rod 21.2 of the damper 21, forming secondary resistance, thereby avoiding noise caused by the door colliding with the cabinet at the end of the closing stage. By rotating the first adjusting screw 11, the adjusting seat 7 is driven to move its upper slider 7.1 and lower slider 7.3 back and forth along the first upper sliding groove 1.2, the first lower sliding groove 1.4, the second upper sliding groove 2.2, and the second lower sliding groove 2.4 on the main body shell 1 and the mounting shell 2. This causes the connected moving plates 6 and 14 and the door to move back and forth. By rotating the second adjusting screw 12, the traction block 8 is driven to move, thereby pushing the front and rear moving plates 6 and 14 to move left and right, achieving fine adjustment of the left and right position of the door. By rotating the third adjusting screw 13 installed on the movable cup seat 5, the force-bearing block 16 and the slider 15 are pushed, thereby adjusting the height of the movable cup seat 5 and achieving vertical adjustment of the door.
[0019] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
