Description

Technical Field

[0001] This application relates to the field of hinge technology, and in particular to a single-piece stamped and bent ultrathin chassis and hinge. Background Technology

[0002] A hinge is a mechanical device used to connect two solid objects and allow them to rotate relative to each other. The two ends of a hinge are installed on a door and a 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, many modern hinges on the market have a thicker base to maintain the stability of the connection between the hinge arm and the base. This design means that when the base is installed in a cabinet, its weight is converted into pressure, which is applied to the screws connecting the base and the cabinet. The screws bear a lot of pressure, and after prolonged use, the stability of the screw connection decreases. The screw holes are also prone to damage or even failure, resulting in a shortened hinge lifespan and a poor user experience.

[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

[0021] The embodiments of this application employing the above-described technical solution may have the following advantages:

[0022] This utility model provides a single-piece stamped and bent ultra-thin chassis and hinge. The ultra-thin chassis includes a single sheet body, which is stamped and folded into two stacked layers. The two layers are defined as a first layer and a second layer. The first layer is bent towards the second layer to form a recessed plate and a sidewall. The recessed plate and sidewall form a clamping part for clamping the hinge arm. This design, by stamping and folding the single sheet body into two stacked layers, reduces the weight of the chassis, thereby reducing the pressure on the screws, improving the stability of the screw connection, and reducing the possibility of screw loosening. At the same time, the structural design of the ultra-thin chassis allows it to fit better with the cabinet, reducing deformation caused by its own weight, thus improving the overall connection stability. In addition, the reduced screw force also reduces the shear force on the screw holes, delaying screw hole damage and failure. This effectively solves the problems of reduced screw connection stability and easy screw hole failure in the prior art, extending the service life of the hinge and improving the user experience. On the other hand, the ultra-thin chassis occupies little space, making the internal space of the cabinet more efficient and aesthetically pleasing. Attached Figure Description

[0037] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. It should be understood that these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein.

[0038] Please refer to the following: Figure 3 and Figure 4 The present application discloses a single-piece stamped and bent ultra-thin chassis (hereinafter referred to as "ultra-thin chassis") in the first aspect, including a single plate body, which is stamped and folded into two stacked plate layers; the two plate layers are defined as a first plate layer 21 and a second plate layer 22, the first plate layer 21 is bent toward the second plate layer 22 to form a recessed plate 212 and a side wall 211, the recessed plate 212 and the side wall 211 form a clamping part for clamping the hinge arm 3. This design, by stamping and folding a single panel into two stacked layers, reduces the weight of the chassis, thereby reducing the pressure on the screws, improving the stability of the screw connection, and reducing the possibility of screw loosening. Simultaneously, the ultra-thin chassis 2's structural design allows for a better fit with the cabinet, reducing deformation caused by its own weight, thus improving overall connection stability. Furthermore, the reduced screw stress also lowers the shear force on the screw holes, delaying screw hole breakage and failure. This effectively solves the problems of reduced screw connection stability and easy screw hole failure in existing technologies, extending the hinge's lifespan and improving the user experience. On the other hand, the ultra-thin chassis 2 occupies less space, resulting in higher utilization of the cabinet's internal space and a more aesthetically pleasing design.

[0039] Specifically, such as Figure 4As shown, the second plate layer 22 includes a first folding plate 221 and a second folding plate 222, which are engaged and connected. When the first folding plate 221 and the second folding plate 222 are engaged and connected, a receiving portion 225 is formed between the two folding plates, and the recessed plate 212 is disposed in the receiving portion 225. One of the first folding plate 221 and the second folding plate 222 is provided with an engaging protrusion 223, and the other is provided with an engaging groove 224. The engaging protrusion 223 and the engaging groove 224 are engaged and connected. Figure 4 As can be seen, in this embodiment, the first folding plate 221 is provided with a locking protrusion 223 and a locking groove 224, and the second folding plate 222 is also provided with a locking protrusion 223 and a locking groove 224. The locking protrusion 223 on the first folding plate 221 is engaged with the locking groove 224 on the second folding plate 222, and the locking groove 224 on the first folding plate 221 is engaged with the locking protrusion 223 on the second folding plate 222. It is understood that multiple locking protrusions 223 can be provided on one folding plate and multiple locking grooves 224 can be provided on another folding plate. Such a variation also falls within the protection scope of this application. The single plate body also includes a folding wall 23. One end of the folding wall 23 is connected to the first plate layer 21, and the other end is connected to the second plate layer 22. The folding wall 23 plays a connecting role, and the height of the folding wall 23 is the thickness of the ultra-thin chassis 2 in this embodiment. Figure 3 and Figure 4 As shown, the first plate layer 21 is provided with a first through hole 215 and a second through hole 216, and the second plate layer 22 is provided with a third through hole 226 and a fourth through hole 227; wherein, the first through hole 215 is correspondingly provided with the third through hole 226, and the second through hole 216 is correspondingly provided with the fourth through hole 227. Screws can pass through the through holes and be threaded to the cabinet body. Since the ultra-thin chassis 2 of this embodiment adopts a single plate body, the deformation caused by its own weight is reduced, thereby improving the overall connection stability. In addition, the reduced force on the screw also reduces the shear force on the screw hole, delaying the damage and failure of the screw hole, effectively solving the problems of reduced screw connection stability and easy failure of screw holes in the prior art, and extending the service life of the hinge.

[0040] Preferably, the third through hole 226 and the fourth through hole 227 are arranged in pairs, and at least one of the third through hole 226 or the fourth through hole 227 is configured as an oblong hole; in this embodiment, the two fourth through holes 227 are oblong holes, 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, so that the ultra-thin chassis 2 can move relative to the screw.

[0041] Please see Figure 5 , Figure 5The embodiments provided in this application are different from Figure 3 Another three-dimensional structural diagram of the ultra-thin chassis 2 is shown in the figure. As can be seen from the figure, in this embodiment, the end of the side wall 211 is provided with a protruding limiting part 217. The limiting part 217 can increase the clamping area of ​​the hinge arm 3. Even if there is a large angle between the hinge arm 3 and the ultra-thin chassis 2, the limiting part 217 can still provide support for the hinge arm 3, which can prevent cantilever between the hinge arm 3 and the ultra-thin chassis 2, and ensure that the center of gravity of the hinge arm 3 is located within the clamping part and the limiting part 217, thus avoiding the increase of torque. Even after long-term use, the connection between the hinge arm 3 and the cabinet will not loosen, shift, or fall off, which greatly extends the service life.

[0042] Please refer to the following: Figure 1 and Figure 2This application discloses a hinge in a second aspect, including a hinge arm 3, a hinge cup 1, and a single-piece stamped and bent ultra-thin base as described in the first aspect above. 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 hinged to the ultra-thin base 2. 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. In this embodiment, the hinge arm 3 includes a first support arm 31. 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 first arm 31. Two arms 32 are hinged together, with the other end hinged to the hinge cup 1 to enhance the connection stability between the hinge cup 1 and the second arm 32. The clamping part of the ultra-thin chassis 2 extends in the first direction, and 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. A movable plate 218 is provided on the recessed plate 212. The movable plate 218 protrudes from the recessed plate 212 in a third direction, forming a gap between the side wall 211 and the movable plate 218 to limit the hinge arm 3. The movable plate 218 is provided with a riveting hole 214. The adjusting member 5 passes through the second support arm 32 and is riveted to the riveting hole 214. 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 member 5 is rotated axially, the hinge arm 3 can move relative to the ultra-thin chassis 2 in the first direction, thereby driving the hinge cup 1 to move in the first direction as well, so as to adjust the gap between the door and the cabinet when installing the door to achieve the best alignment effect.

[0043] like Figure 3As shown, a support plate 219 is also provided on the first plate layer 21, and a notch is provided at the corresponding position of the second plate layer 22. The support plate 219 is engaged in the notch to maintain the relative position of the first plate layer 21 and the second plate layer 22 and prevent displacement. It can be understood that the support plate 219 can also be provided on the second plate layer 22 and the notch can be provided on the second plate layer 21, or there can be multiple support plates 219 and notches, some of which are located on the first plate layer 21 and some of which are located on the second plate layer 22. Such variations are all within the protection scope of this utility model.

[0044] 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 212 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 212 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 212 is provided with a clearance groove 213, which extends along the first direction. The clearance groove 213 provides clearance for the adjusting screw 4. When the adjusting member 5 is rotated, the adjusting screw 4 can reciprocate within the clearance groove 213. Preferably, as shown... Figure 5 As shown, in this embodiment, a protruding limiting part 217 is provided at the end of the side wall 211. The limiting part 217 can increase the clamping area of ​​the hinge arm 3. Even if the hinge arm 3 and the ultra-thin chassis 2 are adjusted to the maximum angle, the second support arm 32 and the adjusting screw 4 will not exceed the plane where the top surface of the limiting part 217 is located in the third direction, thus ensuring the stability and aesthetics of the hinge in this embodiment. The setting of the clamping part and the limiting part 217 can prevent cantilever between the hinge arm 3 and the ultra-thin chassis 2, ensuring that the center of gravity of the hinge arm 3 is located within the clamping part and the limiting part 217, avoiding the increase of torque. Even with long-term use, the connection between the hinge arm 3 and the cabinet will not loosen, shift, or fall off, greatly extending the service life.

[0045] Furthermore, please refer to the following: Figure 6 and Figure 7 To enhance the aesthetics of the hinge, the hinge in this embodiment further includes a first cover plate 6 and a second cover plate 7. The first cover plate 6 is fastened to the hinge cup 1, and the second cover plate 7 is fastened to the ultra-thin chassis 2. Figure 6 and Figure 7 These are two different cover plate styles. Figure 6 When the second cover plate 7 is fastened to the ultra-thin chassis 2, only the hinge arm 3 and the adjusting screw 4 and adjusting piece 5 installed on the hinge arm 3 are exposed; Figure 7 The second cover plate 7 is also provided with a fifth through hole 71. The size of the fifth through hole 71 is similar to that of the second through hole 216, and it can expose the fourth through hole 227 in the third direction.

[0046] Similarly, when it has Figure 5 When mounting the hinge cover on the ultra-thin chassis shown, because the limiting part 217 has a relatively large dimension in the third direction, the second cover 7 must also have a sufficiently large dimension in the third direction to completely cover the limiting part 217. Figure 8 As shown, the second cover plate 7 is completely fastened to the ultra-thin chassis 2, without exposing the hinge arm and the adjusting screw 4 and adjusting component 5 installed on the hinge arm 3.

[0047] Optionally, the hinge in this embodiment further includes a detachable module. A second through hole 216 is provided on the first plate 21, connecting the area between the first plate 21 and the second plate 22 to the external atmosphere. The detachable module is detachably inserted into the second through hole 216. The detachable module includes a colored light panel, a colored cover plate, and / or an air conditioner. The air conditioner can be camphor balls, mite removers, or aromatherapy blocks, etc., and can also be activated carbon or other items with adsorption properties. When the camphor balls, aromatherapy blocks, etc., sublimate or vaporize and gradually dissipate, the detachable module can be directly removed from the second through hole 216 and replaced with a new detachable module. This can regulate the air quality inside the cabinet, remove odors, add fragrance, sterilize, kill insects, remove formaldehyde, etc., meeting the user's needs for air conditioning inside the cabinet and reducing the clutter inside the cabinet caused by placing air conditioners.

[0048] In summary, this application provides a single-piece stamped and bent ultrathin chassis and hinge. The ultrathin chassis 2 includes a single plate body, which is stamped and folded into two stacked plate layers. The two plate layers are defined as a first plate layer 21 and a second plate layer 22. The first plate layer 21 is bent toward the second plate layer 22 to form a recessed plate 212 and a side wall 211. The recessed plate 212 and the side wall 211 form a clamping part for clamping the hinge arm 3. This design, by stamping and folding a single panel into two stacked layers, reduces the weight of the chassis, thereby reducing the pressure on the screws, improving the stability of the screw connection, and reducing the possibility of screw loosening. Simultaneously, the ultra-thin chassis 2's structural design allows for a better fit with the cabinet, reducing deformation caused by its own weight, thus improving overall connection stability. Furthermore, the reduced screw stress also lowers the shear force on the screw holes, delaying screw hole breakage and failure. This effectively solves the problems of reduced screw connection stability and easy screw hole failure in existing technologies, extending the hinge's lifespan and improving the user experience. On the other hand, the ultra-thin chassis 2 occupies less space, resulting in higher utilization of the cabinet's internal space and a more aesthetically pleasing design.
