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 specification, claims and above-mentioned drawings of the present application 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 embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion.

[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 described herein.

[0024] Embodiment 1 Please refer to Figure 1 and Figure 2 simultaneously. The embodiment of the present application provides a modular ultra-thin hinge system based on an integral molding process. The system includes a modular ultra-thin hinge chassis and an ultra-thin hinge arm assembly. The ultra-thin hinge arm assembly is detachably connected to the modular ultra-thin hinge chassis. The modular ultra-thin hinge chassis includes a base and a movable plate. Among them, the base is used for fixedly connecting the cabinet body, and the movable plate is slidably connected to the base. The base includes at least a pair of protruding portions, and the movable plate is clamped between a pair of protruding portions. The protruding portion includes a pair of parallel surfaces. The surface abutting against one side of the cabinet body is defined as the second surface, and the other surface is the first surface; the protruding portion further includes a side wall for clamping the movable plate. One end of the side wall is connected to the first surface, and the other end is connected to the second surface; the first surface, the second surface, and the side wall are configured to be integrally formed. It can be seen that by using the modular ultra-thin hinge chassis based on the integral molding process of the embodiment of the present application, the production process of the base is simple, the processing cost is low, and it is convenient for mass production; and since the base and the movable plate are separately arranged, the manufacturer can mass-produce the base through the integral molding process. After receiving a specified number of orders, the corresponding number or shape of the movable plate and the ultra-thin hinge arm assembly 3 can be produced according to the usage scenario, and finally assembled and shipped, which greatly shortens the working hours.

[0025] The ultra-thin hinge arm assembly 3 of the embodiment of the present application includes a hinge cup 1, a first arm 31 and a second arm 32. Among them, the hinge cup 1 is used to be embedded in a plate body or a door body. One end of the first arm 31 is hingedly connected to the second arm 32, and the other end is hingedly connected to the hinge cup 1. 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 plays a role in limiting the hinge cup 1. The arm head 321 does not abut against the side wall 213 in the first direction, that is, the arm head 321 is not clamped and limited by the inner embedded groove 22. 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. Currently, the common 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 the two protruding parts 21 in the second direction. Without easily causing the arm head 321 and the arm body 322 to break, 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, making the space it occupies in the cabinet smaller and improving the aesthetics.

[0026] Optionally, in this embodiment, the integrally formed process of the base selects die-casting, specifically selects aluminum alloy or zinc alloy, or can also select additive manufacturing of stainless steel materials. Such transformation methods all fall within the protection scope of the present invention and will not be repeated here.

[0027] Specifically, the direction in which the movable plate 4 slides relative to the base 2 is defined as the first direction, and the direction in which a pair of protruding parts 21 face each other is defined as the second direction. Figure 1 In the first direction is the direction indicated by the X arrow, the second direction is the direction indicated by the Y arrow, and the direction indicated by the Z arrow is defined as the third direction. The first direction, the second direction and the third direction are perpendicular to each other pairwise. As Figure 2 and Figure 3As shown, the base 2 of this embodiment includes a pair of protruding portions 21. Each protruding portion 21 includes a pair of parallel surfaces. The surface defined as abutting against one side of the cabinet body is the second surface 212, and the other surface is the first surface 211. The protruding portion 21 further includes a side wall 213. The side wall 213 is used to clamp the movable plate 4. One end of the side wall 213 is connected to the first surface 211, and the other end is connected to the second surface 212. The ultra-thin hinge arm assembly 3 of this embodiment further includes a third arm 33. 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 coincides with at least a part of the first arm 31 and the second arm 32. Specifically, one end of the third arm 33 is hingedly connected to the second arm 32, and the other end is hingedly connected to the hinge cup 1 to enhance the connection stability between the hinge cup 1 and the second arm 32.

[0028] Specifically, the modular ultra-thin hinge system of 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 2 shown. A first shaft hole 323 is formed on the arm body 322, and a second shaft hole 43 is formed on the movable plate 4. The adjusting screw 6 sequentially passes through the first shaft hole 323 and the second shaft hole 43 along the third direction, and is threadedly connected to the first shaft hole 323 and riveted to the second shaft hole 43. When the adjusting screw 6 rotates axially, the meshing position of the adjusting screw 6 with the thread of 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 ultra-thin hinge arm assembly 3 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 first surface 211 is located in the third direction, ensuring the beauty of the hinge system of this embodiment. Currently, the common connection method between the hinge arm and the base of hinges on the market is to arrange both sides of the hinge arm at both ends of the base in the second direction. When adjusting the relative angle between the hinge arm and the base in the third direction, there will be a large part of the hinge arm suspended relative to the base, that is, as the included angle between the hinge arm and the base becomes larger, the area of the projection of the hinge arm along the second direction coinciding with the base becomes smaller, the contact surface decreases, the pressure increases, and the sinking of the door body relative to the cabinet body is aggravated. However, the ultra-thin hinge chassis provided in this embodiment is not only more beautiful in appearance, but also the setting of the embedded groove of the base can prevent the ultra-thin hinge arm assembly 3 from overhanging with respect to the base 2, ensuring that the center of gravity of the ultra-thin hinge arm assembly 3 is located within the embedded groove 22, avoiding the increase of torque. Even after long-term use, there will be no loosening, offset, or detachment of the connection between the ultra-thin hinge arm assembly 3 and the cabinet body, greatly extending the service life.

[0029] Specifically, as Figure 2As 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 and is used to abut 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 46 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. The modular ultra-thin hinge chassis of this embodiment further includes a pin shaft 42. The pin shaft 42 sequentially passes through the first limiting hole 325 and the second limiting hole 46, so that the second arm 32 can rotate relative to the movable plate 4 and perform angle adjustment in the third direction. To ensure that the movable plate 4 and the base 2 do not disengage in the third direction, a chute 214 extending along the first direction is provided on the side wall 213 in this embodiment. In addition to passing through the first limiting hole 325 and the second limiting hole 46, the pin shaft 42 also passes through the chute 214. The chute 214 extends along the first direction, and the pin shaft 42 is slidably connected to the chute 214. Preferably, the chute 214 is configured as a waist-shaped groove, and the two ends of the waist-shaped chute 214 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 42. As Figure 1 shown, for the convenience of assembly in this embodiment, a chute 214 is also provided on at least one side of the base 2 in the second direction. The projection of the chute 214 along the second direction coincides with the chute 214 on the side wall 213. As Figure 2 shown, the modular ultra-thin hinge chassis of this embodiment further includes a first adjusting member 5. A third shaft hole 45 is provided at one end of the movable plate 4 away from the second arm 32 in the first direction. The first adjusting member 5 passes through the third shaft hole 45 and is riveted to the second surface 212 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 5 is rotated axially, the movable plate 4 can move relative to the base 2 in the first direction, thereby driving the ultra-thin hinge arm assembly 3 and the hinge cup 1 to also move in the first direction, so as to adjust the gap size between the door body and the cabinet body when installing the door body and achieve the best alignment effect.

[0030] In an alternative embodiment, as Figure 2As shown in the figure, the modular ultra-thin hinge chassis further includes an adjustment plate 8. At both ends of the adjustment plate 8 along 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 81 and the second slider 82. The cross-sections of the first slider 81 and the second slider 82 along the direction perpendicular to the second direction are both configured to be concave, and are used for snap-fitting connection to the second surface 212 of the base 2 and can slide relative to the second surface 212. A fourth shaft hole 83 is provided on the adjustment plate 8, 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 second surface 212 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 7 is provided at the first through hole 324. The second adjusting member 7 passes through the first through hole 324 and the second through hole 44, penetrates through the through holes at the corresponding positions on the second surface 212, and finally is riveted to the fourth shaft hole 83. Preferably, both the second adjusting member 7 and the first adjusting member 5 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 abutted against the nut to move, so as to achieve the displacement and adjustment functions; as Figure 4 As shown in the figure, when the second adjusting member 7 is axially rotated, the position of the adjustment plate 8 relative to the second surface 212 in the second direction can be adjusted. With such a setting, the door body can move relative to the cabinet body in the second direction, thereby compensating for the errors generated during installation, making the door body and the cabinet body reach the best alignment state, and ensuring the smoothness and sealing performance of opening and closing.

[0031] As an alternative implementation manner, the ultra-thin hinge arm assembly 3 of this embodiment further includes a damping member, and the damping member 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; Figure 5 The ultra-thin hinge system shown in Figure 1 The difference between the ultra-thin hinge system shown in Figure 5 is only in the fixing parts on both sides of the hinge cup 1. Figure 1 In one pair of the fixing parts are respectively installed on both sides of the hinge cup 1 along the second direction. By passing through screws, the hinge cup 1 can be fixed to the door body. Figure 5 The ultra-thin hinge system shown in

[0032] Among them, the adjusting screw 6, the first adjusting member 5, and the second adjusting member 7 can be used to adjust the relative displacements of the modular ultra-thin hinge chassis based on the one-piece forming process in three directions in three-dimensional space, so as to avoid problems such as uneven end faces and obvious gaps as much as possible after installation, improve the appearance aesthetics, and extend the service life of the modular ultra-thin hinge chassis based on the one-piece forming process.

[0033] Embodiment 2 This embodiment is a simplified implementation manner based on Embodiment 1, and the repeated parts will not be elaborated additionally here.

[0034] This embodiment provides a modular ultra-thin hinge system based on the one-piece forming process. Compared with Embodiment 1, the adjusting plate 8 in the hinge system of this embodiment is removed. Correspondingly, the second adjusting member 7 does not need to be provided either; to ensure that the ultra-thin hinge system of this embodiment still has relative displacements in three directions in three-dimensional space, that is, the base 2 still has the function of adjusting its position in the second direction, relief holes for passing screws are provided on both the first surface 211 and the second surface 212 of the convex portion 21. At least two relief holes on the second surface 212 of the base 2 for passing screws are changed from regular circular holes to waist-shaped holes. Based on the shape characteristics of the waist-shaped hole itself: the waist-shaped hole is composed of two semi-circles with the same radius connected by a middle parallel straight line segment, forming a symmetrically long and narrow hole. In this embodiment, the extending direction of the parallel straight line is set parallel to the second direction. Please refer to Figure 4 , Figure 4 It can be seen from [reference] that two pairs of circular relief holes are provided on the first surface 211 of the base. In this embodiment, two pairs of relief holes are also provided on the second surface 212, and at least two relief holes on the second surface 212 are configured as waist-shaped holes. The circular relief holes are arranged corresponding to the waist-shaped holes in the third direction. It can be understood that for the convenience of the screw to penetrate the first surface so that the head of the screw abuts against the second surface, and after tightening, the head of the screw limits the base. The projection of the circular relief hole in the third direction is larger than the projection of the waist-shaped hole, that is, the circumferential dimension of the circular relief hole is larger than the circumferential dimension of the waist-shaped hole. At this time, when the installer adjusts the position of the ultra-thin hinge system of this embodiment in the second direction, the screw can partially pass through the waist-shaped hole and engage with the threaded part on the cabinet body. There is a gap between the head of the screw and the cabinet body to ensure that the base can move relative to the cabinet body in the second direction. After moving to the designated position, tighten the screw so that one side of the second surface abuts against the head of the screw and the other side abuts against the cabinet body. The pressure exerted on the second surface by the thread and the head of the screw together is greater than the gravity of the hinge system itself, preventing the hinge system from shifting.

[0035] Embodiment 3 The difference between this embodiment and Embodiment 1 lies only in the structure of the ultra-thin hinge arm assembly 3, and the repeated parts will not be elaborated additionally here.

[0036] Specifically, please refer to Figure 6 and Figure 7 together. The spans of the second arms 32 of the ultra-thin hinge arm assembly 3 are different, that is, Figure 6 and Figure 7 the heights of the second arms 32 shown in the third direction are different to accommodate door bodies of different thicknesses. It can be understood that the implementation manners of this embodiment are not limited to Figure 6 and Figure 7 two implementation manners. The bending angle between the arm head 321 and the arm body 322 can also be changed, that is, the dimensions of the second arm 32 in the first direction and the third direction are both changed. Such an implementation manner also falls within the protection scope of this application to expand the applicable range of the ultra-thin hinge system.

[0037] In summary, a modular ultra-thin hinge chassis and system based on an integral molding process provided by this application. The modular ultra-thin hinge chassis includes a base and a movable plate. Among them, the base is used to fixedly connect to the cabinet body, and the movable plate is slidably connected to the base. The base includes a pair of protruding parts, and an embedded groove is formed between the two protruding parts. The movable plate is clamped and arranged in the embedded groove. The protruding part includes a pair of parallel surfaces. The surface in contact with the cabinet body is defined as the second surface, and the other surface is the first surface. The protruding part also includes a side wall, and the side wall is used to clamp the movable plate. One end of the side wall is connected to the first surface, and the other end is connected to the second surface. The first surface, the second surface, and the side wall are configured to be integrally molded. It can be seen that by using the modular ultra-thin hinge chassis based on the integral molding process of this application, the production process of the base is simple, the processing cost is low, and it is convenient for mass production. And because the base and the movable plate are separately arranged, the manufacturer can mass-produce the base through the integral molding process. After receiving a specified number of orders, then produce the corresponding number or shape of movable plates and ultra-thin hinge arm assemblies 3 according to the usage scenarios, and finally assemble and ship them, which greatly shortens the working hours.

[0038] It should be noted that the terms used here are only for describing specific implementation manners and are not intended to limit the exemplary implementation manners according to this application. As used here, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should also be understood that when the terms "include" and / or "comprise" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0039] For ease of description, the orientation or positional relationship indicated by orientation terms such as "front, rear, upper, lower, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom", etc. is usually based on the orientation or positional relationship shown in the drawings. This is only for the convenience of describing the present application and simplifying the description. Without contrary explanation, these orientation terms do not indicate or imply that the indicated mechanism or element must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present application; the orientation terms "inside, outside" refer to the inside and outside relative to the contour of each component itself. For example, if the device in the drawing is inverted, the device described as "above other devices or structures" or "on top of other devices or structures" will then be positioned as "below other devices or structures" or "beneath other devices or structures". Thus, the exemplary term "above" can include both the orientations of "above" and "below".
