Description

Technical Field

[0001] The present application relates to the technical field of hinges, and in particular, to a modular ultra-thin hinge chassis and system based on a stamping process. Background Art

[0002] A hinge is a mechanical device used to connect two solids and allow relative rotation between them. The two ends of the hinge are respectively installed on the door body and the cabinet body, and the hinge arm can rotate relative to the door body and the cabinet body to realize the opening and closing of the door body.

[0003] A hinge usually includes a hinge cup, a hinge arm, and a chassis. To expand the application range of the hinge, an adjustment mechanism is usually provided between the hinge arm and the chassis so that the angle between the hinge arm and the chassis can be adjusted. However, most of the common hinges on the market today have the chassis arranged to be clamped on both sides by the hinge arm. When the angle formed between the hinge arm and the chassis becomes larger and larger, the contact area between the two sides of the hinge arm and the chassis becomes smaller and smaller, resulting in an increasing pressure on the contact part between the two sides of the hinge arm and the chassis. This not only makes the connection unstable, but also easily causes fracture, shortening the service life of the hinge and bringing a poor user experience to the user.

It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0021] It should be noted that the terms "first", "second", etc. in the description and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that such terms can be interchanged under appropriate circumstances, so that the implementation manners of the present application described here can be implemented in an order other than those illustrated or described here.

[0023] Next, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. It should be noted that these exemplary embodiments can be implemented in many different forms and should not be construed as being limited only to the embodiments set forth herein.

[0024] Please refer to Figure 1 and Figure 2 Together, an embodiment of the present application provides a modular ultra-thin hinge system based on a stamping process. The system includes a modular ultra-thin hinge chassis and an ultra-thin hinge arm assembly 3. The modular ultra-thin hinge chassis includes a base 2 and a movable plate 4. Among them, the base 2 is used for fixedly connecting the cabinet body, and the movable plate 4 is slidably connected to the base 2. The base 2 includes a plate body 21, and at least a pair of convex portions formed by stamping or bending are provided on the plate body 21. A clamping portion is formed between any pair of convex portions for clamping the movable plate 4 and at least a part of the ultra-thin hinge arm assembly 3. With such a setting, the convex portions manufactured by precision stamping or bending processes have high dimensional accuracy and good process stability. The formed surface exhibits precise and smooth characteristics, and the contour edges maintain clear morphological features. The clamping portion optimized by mechanical design can effectively restrict the relative displacement of the movable plate 4, the ultra-thin hinge arm assembly 3, and the base 2. Combining surface strengthening treatment technology, this structure can still maintain stable tribological performance under long-term reciprocating motion conditions. With a strict quality control system, the hinge system of the present application reaches the durability level specified by industry standards, ensuring a reliable operating experience within the entire life cycle of the hinge system.

[0025] Specifically, define the sliding direction of the movable plate 4 relative to the base 2 as the first direction, that is, Figure 1 and Figure 2 the direction indicated by the X arrow in, when there are multiple pairs of convex portions, the multiple pairs of convex portions are arranged along the first direction. Define the relative direction between any pair of convex portions as the second direction, that is, Figure 1 andFigure 2 In the direction indicated by the Y arrow in Figure 2 , the first direction is perpendicular to the second direction. The direction indicated by the Z arrow is defined as the third direction, and the first, second, and third directions are perpendicular to each other in pairs. In the embodiments of the present application, there are two pairs of raised portions. As shown in Figure 1 , the ultra-thin hinge arm assembly of this embodiment further includes a hinge cup 1. The raised portion closer to the hinge cup 1 is defined as the first raised portion 22, and the raised portion on the other side is defined as the second raised portion 23. The first raised portion 22 and the second raised portion 23 are provided with relief holes 24 on the surface in the third direction, which can accommodate screws to pass through; at least one pair of wing plates 25 formed by stamping or bending are provided on the plate body 21. The wing plates 25 are arranged in the first direction between the first raised portion 22 and the second raised portion 23. The wing plates 25, the first raised portion 22, and the second raised portion 23 together perform the clamping function on the movable plate 4 and the ultra-thin hinge arm assembly 3. The movable plate 4 supports the ultra-thin hinge arm assembly 3 from the inside, making the movement stability of the ultra-thin hinge arm assembly 3 better; the modular ultra-thin hinge chassis of this embodiment further includes a pin shaft 9. The pin shaft 9 passes through the ultra-thin hinge arm assembly 3 and the movable plate 4, enabling the ultra-thin hinge arm assembly 3 and the movable plate 4 to rotate relative to each other in the third direction; a chute 26 is provided on the wing plate 25. The chute 26 is arranged in the first direction; the pin shaft 9 passes through the ultra-thin hinge arm assembly 3 and the movable plate 4 and is slidably connected to the chute 26, enabling the ultra-thin hinge arm assembly 3 and the movable plate 4 to slide relative to the plate body 21 along the first direction with the pin shaft 9; in an alternative embodiment, there may be three pairs of raised portions, and there may be two pairs of wing plates 25. Any pair of wing plates 25 is arranged between the two pairs of raised portions. Correspondingly, there may also be two pairs of chutes 26, and there are also two pin shafts 9, enabling the ultra-thin hinge arm assembly 3 and the movable plate 4 to slide relative to the plate body 21 along the first direction with the pin shafts 9; the ultra-thin hinge arm assembly 3 of this embodiment further includes a first arm 31, a second arm 32, and a third arm 33. Among them, one end of the first arm 31 is hinged to the second arm 32, and the other end is hinged to the hinge cup 1. The end of the second arm 32 away from the first arm 31 is hinged to the movable plate 4; 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 in 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.

[0026] Preferably, in this embodiment, the above-mentioned chute 26 is configured as a waist-shaped groove. The two ends of the waist-shaped chute 26 in the first direction are configured as semi-circular shapes, and the size of the semi-circular shape matches the size of the pin shaft 9, which can limit the pin shaft 9 at the two extreme positions in the first direction.

[0027] ​​The second arm 32 includes an integrally formed arm head 321 and an arm body 322. The arm body 322 is hingedly connected to the movable plate 4, and the arm head 321 is hingedly connected to the first arm 31. When the door body is closed relative to the cabinet body, that is, when the hinge cup 1 contracts relative to the base 2, the arm head 321 functions to limit the hinge cup 1. The arm head 321 does not abut against the side wall in the first direction, that is, the arm head 321 is not clamped and limited by the clamping portion. As is well known to those skilled in the art, the size of the arm head 321 in the second direction is positively correlated with the connection stability between the hinge cup 1 and the ultra-thin hinge arm assembly 3. Commonly available hinges on the market usually design the sizes of the base 2 and the arm head 321 in the second direction to be very large to enhance the connection stability between the hinge cup 1 and the ultra-thin hinge arm assembly 3. However, in this embodiment, the size of the arm head 321 has nothing to do with the size of the base 2 in the second direction. The size of the base 2 in the second direction is only related to the arm body 322. The arm body 322 is hingedly connected to the movable plate 4, and the arm body 322 and the movable plate 4 are clamped by two protrusions in the second direction. Without easily causing fractures of the arm head 321 and the arm body 322, the size of the arm body 322 in the second direction can be designed to be smaller than the size of the arm head 321 in the second direction, so that the size of the base 2 in the second direction can be made very small, occupying a small space in the cabinet and improving the aesthetics.

[0028] Specifically, the ultra-thin hinge arm assembly 3 of the modular ultra-thin hinge system based on the stamping process in this embodiment further includes an adjusting screw 6. The adjusting screw 6 sequentially passes through the arm body 322 of the second arm 32 and the movable plate 4 along the third direction, as Figure 2As shown, a first shaft hole 323 is formed in the arm body 322, and a third shaft hole 45 is formed in the movable plate 4. The adjusting screw 6 sequentially passes through the first shaft hole 323 and the third shaft hole 45 along the third direction, and is threadedly connected to the first shaft hole 323 and riveted to the third shaft hole 45. When the adjusting screw 6 is axially rotated, the meshing position of the screw thread between the adjusting screw 6 and the arm body 322 changes, and the relative position of the second arm 32 and the movable plate 4 in the third direction can be adjusted, that is, the angle of the second arm 32 relative to the movable plate 4 can be adjusted. Preferably, even when the ultra-thin hinge arm assembly 3 and the movable plate 4 are adjusted to form the largest included angle, the arm body 322 and the adjusting screw 6 will not exceed the plane where the relief hole 24 is located in the third direction, ensuring the beauty of the hinge in this embodiment. Currently, the common connection method between the hinge arm and the base 2 of the hinge on the market is to arrange both sides of the hinge arm at both ends of the base 2 in the second direction. When adjusting the relative angle between the hinge arm and the base 2 in the third direction, most of the hinge arm will be suspended relative to the base 2. That is, as the included angle between the hinge arm and the base 2 becomes larger, the overlapping area of the projection of the hinge arm in the second direction and the base 2 becomes smaller, the contact surface decreases, the pressure increases, and the sinking of the door body relative to the cabinet body is aggravated. However, this ultra-thin hinge provided in this embodiment is not only more beautiful in appearance, but also the setting of the clamping part of the base 2 can prevent the occurrence of overhang between the ultra-thin hinge arm assembly 3 and the base 2, ensure that the center of gravity of the ultra-thin hinge arm assembly 3 is located within the clamping part, avoid the increase of torque, and even after long-term use, there will be no loosening, offset and falling off of the connection between the ultra-thin hinge arm assembly 3 and the cabinet body, greatly extending the service life.

[0029] Specifically, as Figure 2 shown, a pair of positioning side plates 41 are provided on the movable plate 4. One side of the positioning side plate 41 extends along the first direction for abutting against the arm body 322 of the second arm 32, and the other side of the positioning side plate 41 extends along the third direction. A second limiting hole 43 is provided on the positioning side plate 41, and a first limiting hole 325 is provided at the corresponding position of the arm body 322. By using the pin shaft 9 to sequentially penetrate the first limiting hole 325 and the second limiting hole 43, the second arm 32 can rotate relative to the movable plate 4 to adjust the angle in the third direction.

[0030] The ultra-thin hinge chassis of this embodiment further includes a first adjusting member 7. A second shaft hole 42 is formed at one end of the movable plate 4 away from the second arm 32 in the first direction. The first adjusting member 7 penetrates the second shaft hole 42 and is riveted to the plate body 21 of the base 2 for adjusting the relative position of the movable plate 4 and the base 2 in the first direction. As Figure 4 shown, when the first adjusting member 7 is axially rotated, the movable plate 4 can move relative to the base 2 along the first direction, thereby driving the ultra-thin hinge arm assembly 3 and the hinge cup 1 to also move along the first direction, so as to adjust the gap size between the door body and the cabinet body when installing the door body to achieve the best alignment effect. Please refer to Figure 3, on the plate body 21, within the area clamped by the two convex portions, a fifth shaft hole 27, a sixth shaft hole 28, and a third through hole 29 are provided. The first adjusting member 7 can pass through the second shaft hole 42 and the fifth shaft hole 27. When the first adjusting member 7 rotates axially, the movable plate 4 can move relative to the base 2 in the first direction; the third through hole 29 is used to make way for the adjusting screw 6 in the third direction.

[0031] In an alternative embodiment, the heights of the first convex portion 22 and the second convex portion 23 in the third direction are set to be relatively low, and the heights of the first convex portion 22 and the second convex portion 23 in the third direction can be the same or different. The relief holes 24 of the first convex portion 22 and the second convex portion 23 are configured as waist-shaped holes. With such a setting, when an installer adjusts the position of the ultra-thin hinge chassis of this embodiment in the second direction, the screw can partially pass through the waist-shaped hole and engage with the threaded portion on the cabinet body, and the head of the screw does not abut against the convex portion, so as to ensure that the base 2 can move relative to the cabinet body in the second direction. After moving to the designated position, tighten the screw so that the head of the screw presses against the convex portion. The pressure exerted on the chassis 5 by the thread and the head of the screw together is greater than the overall gravity of the hinge system itself, preventing the hinge from shifting.

[0032] In an alternative embodiment, as Figure 2 shown, the modular ultra-thin hinge chassis based on the stamping process further includes an adjusting plate 5. At both ends of the adjusting plate 5 in the first direction, a pair of sliders are respectively provided. For the convenience of distinction, the two pairs of sliders are defined as the first slider 51 and the second slider 52. The cross-sections of the first slider 51 and the second slider 52 perpendicular to the second direction are both configured as concave shapes, for snap-fitting connection to the plate body 21 of the base 2 and capable of sliding relative to the plate body 21. A fourth shaft hole 53 is provided on the adjusting plate 5, and a second through hole 44 is opened on the movable plate 4. The second through hole 44 can expose a plurality of through holes on the plate body 21 in the third direction. A first through hole 324 is opened at a corresponding position on the arm body 322 of the second arm 32. A second adjusting member 8 is provided at the first through hole 324. The second adjusting member 8 passes through the first through hole 324 and the second through hole 44, passes through the through holes at the corresponding positions on the plate body 21, and is finally riveted to the fourth shaft hole 53. Preferably, both the second adjusting member 8 and the first adjusting member 7 are configured as eccentric pins. It should be noted that an eccentric pin is a special bolt with an eccentric structure, and the axis of its threaded 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 pin rotates, the threaded shaft is restricted to rotate in the threaded hole, and the nut rotates with an offset along with the threaded shaft, thereby pushing the structure abutting against the nut to move, so as to achieve the displacement and adjustment functions; as Figure 4As shown, when the second adjusting member 8 is axially rotated, the position of the adjusting plate 5 relative to the plate body 21 in the second direction can be adjusted. With such a configuration, the door body can be moved relative to the cabinet body in the second direction, thereby compensating for the error generated during installation, so that the door body and the cabinet body can reach the best alignment state, ensuring the smoothness and sealing of opening and closing.

[0033] In an optional embodiment, the ultra-thin hinge arm assembly 3 of this embodiment further includes a damping member, which is disposed in the hinge cup 1 and is used to provide a damping force when the first arm 31 rotates relative to the hinge cup 1. In this embodiment, the style of the hinge cup 1 is not limited. Figure 1 The hinge cup 1 of the ultra-thin hinge shown is usually suitable for wooden door bodies, and can certainly also be selected to be suitable for aluminum door bodies or door bodies made of other metal materials. Such a change also falls within the protection scope of the present invention.

[0034] Among them, the adjusting screw 6, the first adjusting member 7, and the second adjusting member 8 can be used to adjust the relative displacement of the modular ultra-thin hinge system based on the stamping process in three directions in the three-dimensional space, so that after installation, it can avoid problems such as uneven end faces and obvious gaps as much as possible, improve the appearance, and extend the service life of the modular ultra-thin hinge system based on the stamping process.

[0035] In an optional embodiment, if Figure 5 and Figure 6 As shown, there is no need to set the adjustment plate 5 and the second adjustment member 8. The first protrusion 22 and the second protrusion 23 of the base 2 shown in the figure are Figure 3 The design style is different, the clearance hole 24 is set in a similar way to a sink, and because there is no chassis 5 and the second adjustment member 8, when the construction personnel want to fine-tune the position of the base 2 in the second direction, they can only adjust it manually. To ensure that the ultra-thin hinge system of this embodiment still has relative displacement in three directions in three-dimensional space, preferably, at least one of the four clearance holes on the base 2 is configured as a waist-shaped hole, so that the base 2 can adjust the relative position in the second direction. Based on the shape characteristics of the waist-shaped hole itself: the waist-shaped hole is composed of two semicircles with the same radius connected to a parallel straight line segment in the middle to form a symmetrical narrow and long hole. In this embodiment, the extension direction of the parallel straight lines is set parallel to the second direction. Specifically, Figure 5One relief hole 24 of the first convex part 22 and one relief hole 24 of the second convex part 23 are configured as kidney-shaped holes, and the two are arranged obliquely. It can be understood that the two can also be arranged on the same side in the second direction. Such transformation methods all fall within the protection scope of this application. With such a setting, when the installer adjusts the position of the ultra-thin hinge of this embodiment in the second direction, the screw part can pass through the kidney-shaped hole partially and engage with the threaded part on the cabinet body, and the head of the screw does not abut against the convex part to ensure that the base 2 can move relative to the cabinet body in the second direction. After moving to the designated position, tighten the screw to make the head of the screw press against the convex part. The pressure exerted on the chassis 5 by the thread and the head of the screw is greater than the gravity of the hinge itself to prevent the hinge from shifting; on the other hand, since there is no chassis 5, there is no need to set the second adjusting member 8 either. Figure 3 The sixth shaft hole 28 in Figure 5 is machined into the accommodating hole 20 of

[0036] and an ordinary screw can be passed through.
