Abstract
Description
Technical Field
[0001] This application relates to the field of hinge technology, and more particularly to a single-piece stamped ultrathin hinge. Background Technology
[0002] A hinge is a mechanical device used to connect two solids and allow them to rotate relative to each other. The two ends of the hinge are installed on the door and the cabinet respectively. The hinge arm can rotate relative to the door and the cabinet to open and close the door.
[0003] Hinges typically consist of a hinge cup, a hinge arm, and a base. To broaden the hinge's applicability, the hinge arm and base are usually adjustable in angle. However, in common hinges on the market, the through holes on the base are not covered, leaving them exposed. This affects the product's aesthetics and allows dust and debris to easily enter, potentially damaging the screw holes. Furthermore, the limiting structure between the hinge arm and the base is unstable, causing the hinge arm to wobble or detach from the base, resulting in an unstable connection. This affects normal movement and performance, and may even lead to equipment damage or safety accidents.
[0004] It should be noted that the above content is not necessarily prior art, nor is it intended to limit the scope of patent protection of this application. Utility Model Content

[0020] Optionally, it also includes an adjusting member, which passes through the hinge arm and the ultra-thin chassis and is riveted to the ultra-thin chassis, for adjusting the relative position of the hinge arm and the ultra-thin chassis in a first direction.
[0021] Optionally, the hinge arm includes a first arm and a second arm that are hinged to each other, the end of the first arm away from the second arm is hinged to the hinge cup, and the end of the second arm away from the first arm is connected to the ultra-thin chassis.
[0022] The embodiments of this application employing the above-described technical solution may have the following advantages:
[0023] This utility model provides a single-piece stamped ultra-thin hinge, including a hinge cup, an ultra-thin base, and a hinge arm. The hinge cup is used to embed into a door or panel, the ultra-thin base is used to fix and connect to a cabinet, one end of the hinge arm is hinged to the hinge cup, and the other end is connected to the ultra-thin base. The hinge cup includes a cup head and a first cover plate, the first cover plate being detachably connected to the cup head. The ultra-thin base includes a base and a second cover plate, the second cover plate being detachably connected to the base. The base is stamped from a single piece of sheet metal, including a body, a stamped recessed plate, and a side wall. A connecting plate is provided on the recessed plate, protruding upwards from the recessed plate. A gap is formed between the side wall and the connecting plate to limit the hinge arm. With this design, in existing technologies, without a concealing design, the through holes on the hinge cup and base are directly exposed, ruining the overall visual effect of the hinge and making the product appear less refined. After the first and second cover plates conceal the through holes, the entire hinge surface appears more complete, like a single piece without any extra holes, enhancing the product's aesthetics. Furthermore, the first and second cover plates prevent external dust and debris from entering the through holes. If the through holes are exposed for a long time, dust accumulation can damage the screws inside, affecting the precision of the screw fit with the cabinet, and consequently impacting the stability of the connection between the hinge and the door / cabinet. Concealing the through holes effectively protects the screws and the cabinet's threaded structure, extending their lifespan. The double-sided limiting design of the connecting plate and sidewalls greatly improves the reliability of the connection. Because the gap between the sidewalls and the connecting plate limits the hinge arm, it is less likely for the hinge arm to detach from the chassis, thus ensuring a stable connection between the hinge and the chassis. This avoids equipment damage or safety accidents caused by hinge detachment during use, such as in scenarios requiring frequent opening and closing, like the connection between ultra-thin cabinet doors and the cabinet body. This stable connection ensures normal equipment function, reduces maintenance costs, and extends product lifespan. Attached Figure Description

[0035] Please refer to the following: Figure 1 and Figure 2This application discloses a single-piece stamped ultra-thin hinge, including a hinge cup 1, an ultra-thin base 2, and a hinge arm 3. The hinge cup 1 is used to embed into a door or panel, the ultra-thin base 2 is used to fix and connect to a cabinet, one end of the hinge arm 3 is hinged to the hinge cup 1, and the other end is connected to the ultra-thin base 2. The hinge cup 1 includes a cup head 11 and a first cover plate 12, which is detachably connected to the cup head 11. The ultra-thin base 2 includes a base 21 and a second cover plate 22, which is detachably connected to the base 21. The base 21 is stamped from a single piece of sheet metal and includes a body, a stamped recessed plate 213, and a side wall 212. A connecting plate 214 is provided on the recessed plate 213, which protrudes from the recessed plate 213 in a third direction. A gap is formed between the side wall 212 and the connecting plate 214 to limit the hinge arm 3. In existing technology, without a concealing design, the through holes on the hinge cup 1 and the base are directly exposed, ruining the overall visual effect of the hinge and making the product appear less refined. However, with the first cover plate 12 and the second cover plate 22 concealing the through holes, the entire hinge surface appears more complete, like a single unit without extra holes, enhancing the product's aesthetics. Furthermore, the first cover plate 12 and the second cover plate 22 prevent external dust and debris from entering the through holes. If the through holes are exposed for a long time, dust accumulation can damage the screws inside, affecting the precision of the screw fit with the cabinet, and consequently affecting the stability of the connection between the hinge and the door / cabinet. Concealing the through holes effectively protects the screws and the cabinet's threaded structure, extending their service life. The double-sided limiting design of the connecting plate 214 and the side wall 212 greatly improves the reliability of the connection. Because the gap between the side wall 212 and the connecting plate 214 limits the hinge arm 3, the hinge arm 3 is less likely to detach from the base, thus ensuring a stable connection between the hinge and the base. This can prevent equipment damage or safety accidents caused by hinge detachment during use, such as in scenarios that require frequent opening and closing, like the connection between ultra-thin cabinet doors and the cabinet body. This stable connection can ensure the normal functioning of the equipment, reduce maintenance costs, and extend the product's lifespan.
[0036] Specifically, the direction indicated by the X arrow in the figure is defined as the first direction, the direction indicated by the Y arrow as the second direction, and the direction indicated by the Z arrow as the third direction. The hinge arm 3 in this embodiment includes a first arm 31, a second arm 32, and a third arm 33. The first arm 31 and the second arm 32 are hinged together. The end of the first arm 31 away from the second arm 32 is hinged to the hinge cup 1, and the end of the second arm 32 away from the first arm 31 is hinged to the movable plate. The third arm 33 is located below the first arm 31 and the second arm 32 in the Z-axis direction, that is, the projection of the third arm 33 along the third direction at least partially coincides with the first arm 31 and the second arm 32. Specifically, one end of the third arm 33 is hinged to the second arm 32, and the other end is hinged to the hinge cup 1 to enhance the connection stability between the hinge cup 1 and the second arm 32.
[0037] The recessed plate 213 and side wall 212 of the ultra-thin chassis 2 form a clamping part, and the extension direction of the clamping part is a first direction. The hinge arm 3 can reciprocate within the clamping part along the first direction. Specifically, the hinge includes an adjusting member 5, which passes through the hinge arm 3 and the ultra-thin chassis 2 and is riveted to the ultra-thin chassis 2. It is used to adjust the relative position of the hinge arm 3 and the ultra-thin chassis 2 in the first direction. The connecting plate 214 is provided with a riveting hole 215. The adjusting member 5 passes through the second support arm 32 and is riveted to the riveting hole 215. In this embodiment, the adjusting member 5 is configured as an eccentric nail. It should be noted that an eccentric nail is a special bolt with an eccentric structure. The axis of its thread shaft does not coincide with the geometric center of the nut, but has a certain offset relative to the geometric center of the nut. When the eccentric nail rotates, the thread shaft is confined to rotate in the threaded hole, and the nut rotates with the offset of the thread shaft, thereby pushing the structure against the nut to move, so as to realize the displacement and adjustment functions. When the adjusting component 5 is rotated axially, the hinge arm 3 can move relative to the ultra-thin chassis 2 in the first direction, thereby causing the hinge cup 1 to also move in the first direction, so as to adjust the gap between the door and the cabinet when installing the door, and achieve the best alignment effect.
[0038] Furthermore, such as Figure 1 As shown, the hinge in this embodiment also includes an adjusting screw 4. The adjusting screw 4 is sequentially inserted into the second arm 32 and the countersunk plate 213 along a third direction. When the adjusting screw 4 is rotated axially, the engagement position of the threads of the adjusting screw 4 and the second arm 32 changes, which can adjust the relative position of the second arm 32 and the countersunk plate 213 in the third direction, that is, adjust the height and angle of the hinge arm 3 relative to the ultra-thin chassis 2. The countersunk plate 213 is provided with a clearance groove 217, which extends along the first direction. The clearance groove 217 makes way for the adjusting screw 4. When the adjusting member 5 is rotated, the adjusting screw 4 can reciprocate within the clearance groove 217.
[0039] Please refer to the following: Figure 3 and Figure 4The ultra-thin chassis 2 of this application embodiment includes a base 21 and a second cover plate 22. The base 21 is stamped from a single sheet of plate. The second cover plate 22 is detachably connected to the base 21 and is used to cover the through holes on the base 21. The base 21 includes a plate 211, a stamped recessed plate 213, and a side wall 212. A connecting plate 214 is provided on the recessed plate 213. The connecting plate 214 protrudes from the recessed plate 213 in a third direction. A gap is formed between the side wall 212 and the connecting plate 214 to limit the hinge arm 3. This arrangement, with the double-sided limiting design of the connecting plate 214 and the side wall 212, greatly improves the reliability of the connection. Since the gap between the side wall 212 and the connecting plate 214 limits the hinge arm 3, the hinge arm 3 is not easy to detach from the ultra-thin chassis 2, thereby ensuring a stable connection between the hinge and the ultra-thin chassis 2. This can prevent equipment damage or safety accidents caused by hinge detachment during use, such as in scenarios that require frequent opening and closing, like the connection between ultra-thin cabinet doors and the cabinet body. This stable connection can ensure the normal functioning of the equipment, reduce maintenance costs, and extend the product's lifespan.
[0040] Specifically, such as Figure 4As shown, one of the base 21 and the second cover plate 22 is provided with a locking groove 210, and the other is provided with a locking protrusion 221. The locking groove 210 and the locking protrusion 221 are engaged and connected. In this embodiment, the locking groove 210 is provided on the plate 211 of the base 21, and the locking protrusion 221 is provided on the second cover plate 22. Of course, the locking groove 210 can also be provided on the second cover plate 22, and the locking protrusion 221 can be provided on the plate 211. Even more specifically, the second cover plate 22 is provided with both the locking protrusion 221 and the locking groove 210, and the plate 211 is also provided with both the locking protrusion 221 and the locking groove 221. 10. The engaging protrusion 221 and engaging groove 210 are respectively connected, and such transformations all fall within the protection scope of this utility model; the hinge cup 1 includes a first cover plate 12 and a cup head 11. The first cover plate 12 is detachably fastened to the cup head 11. In some embodiments, the engaging structure of the first cover plate 12 and the cup head 11 is the same as the engaging structure of the base 21 and the second cover plate 22, which will not be described in detail here; the end of the recessed plate 213 away from the connecting plate 214 is provided with a relief groove 217. The relief groove 217 is used to allow the adjustment screw 4 to move along the first direction, preventing the adjustment screw 4 from being in the first direction. The bottom of the third direction interferes with the movement of the recessed plate 213 of the base 21; a cut 216 is provided between the connecting plate 214 and the recessed plate 213, and the cut 216 is configured as a semi-enclosed shape, so that the connecting plate 214 and the recessed plate 213 have a certain degree of freedom in the third direction, and the two can move relative to each other; the plate body 211 is provided with a first through hole 218 and a second through hole 219, and the first through hole 218 and the second through hole 219 are both provided in pairs at the ends of the plate body 211. Since the base 21 in this embodiment is cuboid, the large surface of the base 21 in the third direction is rectangular, and any one of the first through holes Both the first through hole 218 and the second through hole 219 are located near the vertices of the rectangle. Furthermore, the first through hole 218 and the second through hole 219 are configured as countersunk grooves. With this configuration, the countersunk grooves can act as guide screws, guiding the screws to align with the screw holes on the cabinet when tightening them. Preferably, at least one of the first through holes 218 or the second through hole 219 is configured as an oblong hole along a third direction. Based on the shape characteristics of the oblong hole itself: the oblong hole is formed by two semicircles of the same radius connected by a parallel straight line segment in the middle, forming a symmetrical, narrow hole, which allows the ultra-thin chassis 2 to move relative to the screws.
[0041] Understandably, because the connecting plate 214 protrudes from the recessed plate 213 in the third direction, gaps are formed between the side wall 212 and the connecting plate 214 on both sides in the second direction, which enables the hinge arm 3 to be clamped and fixed. The hinge arm 3 is less likely to detach from the ultra-thin chassis 2, thus ensuring a stable connection between the hinge and the ultra-thin chassis 2. This can prevent equipment damage or safety accidents caused by hinge detachment during use, such as in scenarios requiring frequent opening and closing, like the connection between ultra-thin cabinet doors and the cabinet body. This stable connection ensures the normal functioning of the equipment, reduces maintenance costs, and extends the product's service life.
[0042] In summary, this application provides a single-piece stamped ultra-thin hinge, comprising a hinge cup 1, an ultra-thin base 2, and a hinge arm 3. The hinge cup 1 is used to embed into a door or panel, the ultra-thin base 2 is used to fix and connect to a cabinet, and one end of the hinge arm 3 is hinged to the hinge cup 1, while the other end is connected to the ultra-thin base 2. The hinge cup 1 includes a cup head 11 and a first cover plate 12, which are detachably connected to the cup head 11. The ultra-thin base 2 includes a base 21 and a second cover plate 22, which are detachably connected to the base 21. The base 21 is stamped from a single piece of sheet metal and includes a body, a stamped recessed plate 213, and a side wall 212. A connecting plate 214 is provided on the recessed plate 213, which protrudes from the recessed plate 213 in a third direction. A gap is formed between the side wall 212 and the connecting plate 214 to limit the hinge arm 3. In existing technology, without a concealing design, the through holes on the hinge cup 1 and the base are directly exposed, ruining the overall visual effect of the hinge and making the product appear less refined. However, with the first cover plate 12 and the second cover plate 22 concealing the through holes, the entire hinge surface appears more complete, like a single unit without extra holes, enhancing the product's aesthetics. Furthermore, the first cover plate 12 and the second cover plate 22 prevent external dust and debris from entering the through holes. If the through holes are exposed for a long time, dust accumulation can damage the screws inside, affecting the precision of the screw fit with the cabinet, and consequently affecting the stability of the connection between the hinge and the door / cabinet. Concealing the through holes effectively protects the screws and the cabinet's threaded structure, extending their service life. The double-sided limiting design of the connecting plate 214 and the side wall 212 greatly improves the reliability of the connection. Because the gap between the side wall 212 and the connecting plate 214 limits the hinge arm 3, the hinge arm 3 is less likely to detach from the base, thus ensuring a stable connection between the hinge and the base.
