Description

Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to a thin hinge with bidirectional buffering function. Background Technology

[0002] Hinges are commonly used to connect the cabinet body and doors of wardrobes or cabinets, enabling the doors to open and close. As people's pursuit of quality of life and home products continues to increase, they are increasingly inclined towards products that are exquisite and compact. Traditional hinges typically use a combination of torsion springs and dampers to achieve automatic, slow closing of the door. However, adding a torsion spring increases the overall size of the hinge, resulting in a thicker hinge.

[0003] The invention patent with publication number CN118346136A specifically discloses a hinge with a damper. According to its disclosed technical content and drawings, the damping component consists of a hydraulic damper and a spring connected in series. The structure is simple and compact, easy to install, simplifies the installation process of the hydraulic damper and spring, and also reduces the installation size of the damper in the width direction, which is conducive to the compact design of the hinge, and the hinge as a whole looks thinner.

[0004] Meanwhile, in practical applications, hinges require adjustment of the door's position in the vertical, horizontal, and front-back directions to ensure alignment with the cabinet and improve installation quality. However, in existing technologies, the damping components, consisting of a series-connected hydraulic damper and spring, already occupy the middle position of the first hinge unit. Adding further components to the first hinge unit to adjust the door's position in these directions would result in a thicker hinge overall, necessitating adjustments. Utility Model Content

[0008] As a further solution, a guide portion is fixed between the first driving part and the eccentric part, and a guide groove is provided on the edge of the waist-shaped hole, with the guide portion and the guide groove being movably engaged.

[0009] As a further embodiment, positioning plates are fixed on both sides of the slide block, and a guide plate protrudes from the bottom of the first receiving groove. The guide plate extends along the length of the hinge arm and is far away from the eccentric wheel. The positioning plate on one side of the slide block abuts against the guide plate, and the positioning plate where the waist-shaped hole is located abuts against the groove wall of the first receiving groove.

[0010] As a further embodiment, a limiting plate protrudes from the bottom of the first receiving groove. The limiting plate is located on one side of the slide and is close to the eccentric wheel. The positioning plate where the waist-shaped hole is located can abut against the limiting plate.

[0011] As a further embodiment, the hinge also includes an adjusting member rotatably connected to the slide, the adjusting member passing through the hinge arm and screwed to the hinge arm, the adjusting member being located away from the rotatable connection between the hinge arm and the slide.

[0012] As a further embodiment, the bottom of the adjusting member is riveted to the slide block, the hinge arm has a mounting hole, the edge of the mounting hole has a threaded sleeve protruding downwards, the adjusting member is threaded to the threaded sleeve, and the top surface of the adjusting member is provided with a second driving part.

Since the slide is used to install the spring and hydraulic damper, considering the need for the hinge to have a bidirectional buffering function, in order to reduce the thickness of the slide, i.e., the thickness of the entire hinge, a positioning plate is fixed on the side wall of the slide. An oblong hole is provided on the positioning plate, and an eccentric wheel is movably engaged with the oblong hole. This allows the eccentric wheel that drives the slide to move in the front-back direction to be positioned on one side of the slide, thereby reducing the thickness of the entire hinge in the left-right direction, making it thinner.

Detailed Implementation

[0026] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0027] It should be noted that, as shown in the attached document... Figure 8 As shown in the following description, the up-down direction is perpendicular to the horizontal plane and perpendicular to the length direction of the hinge arm 3; the left-right direction is parallel to the horizontal plane and perpendicular to the length direction of the hinge arm 3; the front-back direction is parallel to the horizontal plane and also parallel to the length direction of the hinge arm 3.

[0028] As attached Figure 1-2 As shown, this embodiment provides a thin hinge with bidirectional buffering function, including a hinge cup 1 and a base 2. The base 2 has a first receiving groove 21 in the middle. The hinge also includes a hinge arm 3, a slide 4, a hydraulic damper 5, a spring 6 and an eccentric wheel 7. The slide 4 is placed in the first receiving groove 21, and a second receiving groove 41 is provided on the slide 4. The hydraulic damper 5 and the spring 6 are both installed in the second receiving groove 41. Specifically, one end of the spring 6 abuts against the cylinder 51 of the hydraulic damper 5, and the other end of the spring 6 abuts against the inner wall of the second receiving groove 41. That is, the axes of the spring 6 and the hydraulic damper 5 are in the same direction. The deformation of the spring 6 provides the closing force for closing the door 101, and the hydraulic damper 5 provides the buffering force for opening or closing the door 101.

[0029] One end of the hinge arm 3 is rotatably connected to the slide block 4, and the other end of the hinge arm 3 is rotatably connected to the hinge cup 1 through the first connecting piece 8 and the second connecting piece 82 respectively. The piston rod 52 of the hydraulic damper 5 is rotatably connected to the second connecting piece 82 through the adapter 83. Specifically, the aforementioned rotatable connection is achieved by a pin.

[0030] During installation, the hinge cup 1 is mounted on the door body 101, and the base 2 is mounted on the inner wall of the cabinet body 10. Specifically, the base 2 has two fixing holes 22, located on both sides of the slide 4. Screws are used to pass through the fixing holes 22 to mount the base 2 onto the inner wall of the cabinet body 10 for fixation.

[0031] The working principle of this hinge is as follows: When the spring 6 is compressed, a closing force is generated on the door 101. When the door is opened to 90°, the elastic force of the spring 6 is greater than the damping force of the hydraulic damper 5. The hydraulic damper 5 then begins to function, with its piston rod 52 retracting inward to provide damping for the door 101, preventing it from wobbling after opening to 90°. This is the first-direction buffering. As the door 101 is about to close, the piston rod 52 of the hydraulic damper 5 extends outward, again providing damping for the door 101, preventing it from colliding with the cabinet 10 when closing. This is the second-direction buffering, achieving bidirectional buffering and thus giving the hinge a bidirectional buffering function.

[0032] A positioning plate 42 is fixed to at least one side wall of the slide 4. Specifically, the positioning plate 42 is fixed to the side wall of the slide 4 by integral molding or welding. The positioning plate 42 extends to the groove wall of the first receiving groove 21, thereby positioning and guiding the slide 4, so that the slide 4 will not deviate in the vertical direction when adjusted along the length direction of the hinge arm 3. The positioning plate 42 has an oblong hole 421. The bottom of the eccentric wheel 7 is rotatably connected to the bottom of the groove of the first receiving groove 21, so that the eccentric wheel 7 can rotate relative to the base 2. The axis of rotation of the eccentric wheel 7 is perpendicular to the length direction of the hinge arm 3 and parallel to the horizontal plane. The eccentric wheel 7 is placed in the oblong hole 421, and the eccentric wheel 7 is movably engaged with the oblong hole 421, so that the slide 4 can move along the length direction of the hinge arm 3, that is, in the front-back direction, the gap between the door 101 and the cabinet 10 can be adjusted.

[0033] The working principle of the eccentric wheel 7 and the oblong hole 421 in a movable engagement: The eccentric wheel 7 can be rotated. Since the center of the eccentric wheel 7 is not at the rotation point, the distance between the farthest position of the eccentric wheel 7 on its outer edge and the rotation point is not equal to the distance between the closest position of the eccentric wheel 7 on its outer edge and the rotation point. Therefore, when the action is applied to the farthest position and gradually moved to the closest position, a displacement variable will be generated, which is the adjustable displacement variable of the eccentric wheel 7. When the eccentric wheel 7 rotates, since the base 2 is fixed, the position of the rotation point remains unchanged. When the eccentric wheel 7 and the oblong hole 421 rotate in engagement, the positioning plate 42 causes the slide block 4 to slide in the length direction of the hinge arm 3, that is, in the front-back direction, thereby realizing the linear sliding adjustment of the hinge arm 3 in the front-back direction, and thus achieving the purpose of adjusting the front-back offset position of the hinge arm 3.

[0034] In this design, a first receiving groove 21 is provided in the middle of the base 2, and the slide 4 is placed in the first receiving groove 21. A second receiving groove 41 is provided on the slide 4. The hydraulic damper 5 and the spring 6 are both installed in the second receiving groove 41. The deformation of the spring 6 provides the closing force for closing the door 101, and the hydraulic damper 5 provides the buffering force for opening or closing the door 101, thus achieving bidirectional buffering and giving the hinge a bidirectional buffering function. Since the slide 4 is used to install the spring 6 and the hydraulic damper 5, in order to reduce the thickness of the slide 4, i.e. the thickness of the entire hinge, while ensuring the hinge has a bidirectional buffering function, a positioning plate 42 is fixed on the side wall of the slide 4. An oblong hole 421 is provided on the positioning plate 42, and the eccentric wheel 7 is movably engaged with the oblong hole 421. Thus, the eccentric wheel 7 that drives the slide 4 to move in the front-back direction is set on one side of the slide 4, thereby reducing the thickness of the entire hinge in the left-right direction, making it thinner.

[0035] For details, see attached. Figure 5 As shown, the eccentric wheel 7, from top to bottom, includes a first drive part 71, an eccentric part 72, and a rotating shaft part 73, which are fixedly connected. The fixed connection is either integrally formed or welded. The eccentric part 72 is movably fitted with the oblong hole 421, and the length direction within the oblong hole 421 is consistent with the length direction of the hinge arm 3. The rotating shaft part 73 is riveted to the bottom of the first receiving groove 21. The first drive part 71 can be a slotted or Phillips headstock suitable for screwdrivers, or an internal hexagonal headstock suitable for hex wrenches. A screwdriver or hexagonal wrench is inserted into the slotted, Phillips headstock, or internal hexagonal headstock to apply force by turning the first drive part 71, thereby causing the eccentric part 72 to rotate relative to the base 2. As shown in the attached diagram... Figure 7 As shown, due to the movable engagement of the eccentric portion 72 and the oblong hole 421, the length direction of the oblong hole 421 is parallel to the length direction of the hinge arm 3. Under the movable engagement of the eccentric portion 72 and the oblong hole 421, the slide block 4 and the hinge arm 3 are pushed to move in the front-back direction, thereby adjusting the front-back offset position of the door body 101.

[0036] Based on the above, as shown in the appendix Figure 5 As shown, a guide portion 74 is further fixed between the first driving part 71 and the eccentric part 72, wherein the fixed connection is integrally formed or welded. A guide groove 422 is provided on the edge of the waist-shaped hole 421, and the guide portion 74 is movably engaged with the guide groove 422. Through the engagement of the guide portion 74 and the guide groove 422, the eccentric wheel 7 can stably drive the slide block 4 to move back and forth.

[0037] In some embodiments, as shown in the appendix Figure 2-4 As shown, positioning plates 42 are fixed on both sides of the slide 4. A guide plate 211 protrudes from the bottom of the first receiving groove 21. The guide plate 211 extends along the length of the hinge arm 3 and is far away from the eccentric wheel 7. The positioning plate 42 on one side of the slide 4 abuts against the guide plate 211. The positioning plate 42 where the waist-shaped hole 421 is located abuts against the groove wall of the first receiving groove 21. The positioning plates 42 on both sides of the slide 4 keep the slide 4 in the center position of the first receiving groove 21 of the base 2. During the process of adjusting the forward and backward offset position of the slide 4, it is ensured that the slide 4 will not shift in the vertical direction, while maintaining the stability of the forward and backward offset of the slide 4.

[0038] Based on the above embodiments, as shown in the appendix Figure 2-4 As shown, the bottom of the first receiving groove 21 protrudes from the limiting plate 212. The limiting plate 212 is located on one side of the slide 4 and is close to the eccentric wheel 7. The positioning plate 42 where the waist-shaped hole 421 is located can abut against the limiting plate 212. The limiting plate 212 limits the front and back offset of the positioning plate 42, which limits the front and back offset of the slide 4 and the hinge arm 3, so as to avoid the front and back offset of the door 101 being too large.

[0039] As attached Figure 3 As shown, the hinge also includes an adjusting member 9, which is rotatably connected to the slide 4. The adjusting member 9 passes through the hinge arm 3 and is screwed onto the hinge arm 3. The adjusting member 9 is located away from the rotatable connection between the hinge arm 3 and the slide 4. The axis of the adjusting member 9 is parallel to the left-right direction. When the adjusting member 9 is turned, the adjusting member 9 and the hinge arm 3 are screwed together, thereby adjusting the relative position between the hinge arm 3 and the slide 4 in the left-right direction, that is, adjusting the angle between the hinge arm 3 and the slide 4, thereby adjusting the left-right offset position of the hinge arm 3.

[0040] In some embodiments, the bottom of the adjusting member 9 is riveted to the slide 4, thereby connecting the adjusting member 9 to the slide 4. The adjusting member 9 also connects the slide 4 to the hinge arm 3. The rotating shaft 73 of the eccentric wheel 7 is riveted to the bottom of the first receiving groove 21, further connecting the slide 4 to the base 2, forming an integrated force-bearing structure with stronger overall integrity.

[0041] Furthermore, to facilitate the installation of adjustment component 9, as shown in the attached document... Figure 3-4 As shown, a mounting hole 31 is provided in the hinge arm 3, and a threaded sleeve 32 protrudes downward from the edge of the mounting hole 31. The adjusting member 9 is screwed to the threaded sleeve 32, and a second driving part 91 is provided on the top surface of the adjusting member 9. The second driving part 91 can be referenced from the first driving part 71. A screwdriver or wrench passes through the mounting hole 31 and turns the second driving part 91. Through the screwing of the adjusting member 9 and the threaded sleeve 32, the force is ensured to be stable, thereby lifting the hinge arm 3 and adjusting the relative position between the hinge arm 3 and the slide block 4.

[0042] Meanwhile, as attached Figure 2-4 As shown, there are locking blocks 43 fixed on the two side walls of the slide 4. The first receiving groove 21 is provided with two slots 213 with one end open. The locking blocks 43 are inserted into the slots 213 through the opening and move in cooperation with the slots 213, thereby preventing the slide 4 from detaching from the base 2 in the left and right direction; while in the front and back direction, the slide 4 and the base 2 can be offset relative to each other.

[0043] As attached Figure 3 , 7 As shown, the piston rod 52 of the hydraulic damper 5 passes sequentially through the groove wall at one end of the second receiving groove 41 and the groove wall at one end of the first receiving groove 21. One end of the adapter 83 is rotatably connected to one end of the second connecting member 82, and the other end of the adapter 83 is rotatably connected to the piston rod 52 of the hydraulic damper 5. One end of the first connecting member 8 and the second connecting member 82 are rotatably connected to the other end of the hinge arm 3, and the other ends of the first connecting member 8 and the second connecting member 82 are rotatably connected to the hinge cup 1. The first connecting member 8 is provided with a locking position 81, and one end of the second connecting member 82 is locked in the locking position 81, so that when the door 101 is opened to nearly 90°, the door 101 is positioned by the locking position 81, keeping the door 101 in an open state of 90° or more. The rotatable connection is achieved through a pin.

[0044] The aforementioned hinge arm 3, second connector 82, adapter 83, hydraulic damper 5, and slide 4 form a five-bar connection structure, thereby ensuring that the hydraulic damper 5 is always under stress.

[0045] To maintain an aesthetically pleasing appearance, the hinge also includes a cover (not shown in the figure) that covers and secures the opening of the first receiving groove 21, thereby enhancing the overall appearance.

[0046] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
