[0044] Example One

[0045] Reference is also made to Figure 1 and Figure 2The embodiment of the application provides a kind of based on integrated forming process's ultra-thin hinge, including hinge cup 1, pedestal 2, movable plate 4 and ultra-thin hinge arm 3, wherein, hinge cup 1 is used to embed plate body or door body, pedestal 2 is used to fixedly connected cabinet, movable plate 4 is slidably connected to pedestal 2, ultra-thin hinge arm 3 one end is hingedly connected with hinge cup 1, the other end is hingedly connected with movable plate 4, pedestal 2 uses integrated forming process design, pedestal 2 includes at least a pair of protruding parts 21, a pair of protruding parts 21 form inner embedded groove 22, movable plate 4 is placed in inner embedded groove 22, is clamped by two protruding parts 21, pin shaft 42 is provided on ultra-thin hinge arm 3, pin shaft 42 penetrates movable plate 4 and pedestal 2, so that ultra-thin hinge arm 3, movable plate 4 and pedestal 2 can be rotated relative to pin shaft 42.It can be seen that, using the ultra-thin hinge based on integrated forming process of the application, ultra-thin hinge arm 3 is hingedly connected with movable plate 4, movable plate 4 is clamped by integrated pedestal 2, and can slide relative to pedestal 2 to adjust the relative position of door body and hinge, and then adjust the relative position of door body and cabinet, compensate installation error, so that door body and cabinet reach the best alignment state, the base of the ultra-thin hinge based on integrated forming process of the application has simple production procedure, low processing cost and is convenient for mass production;And because pedestal 2 is separately arranged with movable plate 4 and ultra-thin hinge arm 3, manufacturers can mass-produce pedestal 2 by integrated forming process, produce corresponding number or shape of ultra-thin hinge arm 3 and movable plate 4 according to actual use scene after receiving specified number of hinge procurement orders, and finally assemble and ship, which greatly shortens working hours.

[0046] Optionally, in the embodiment, the pedestal is made of die casting forming process, and the die casting material is metal material, specifically aluminum alloy or zinc alloy;In addition to die casting process, in some alternative embodiments, stainless steel additive process can also be used for production of the pedestal, and such transformation mode is within the protection scope of the application, and will not be repeated here.

[0047] Specifically, the direction of the sliding of the movable plate 4 relative to the pedestal 2 is defined as the first direction, the opposite direction of the pair of protruding parts 21 is defined as the second direction, Figure 1 The first direction is the direction indicated by the X arrow, the second direction is the direction indicated by the Y arrow, 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. Figure 2 And Figure 3As shown, the protruding part 21 in the embodiment is provided with a pair, and each protruding part 21 includes a pair of parallel surfaces, defining the surface abutting the side of the cabinet as the second surface 212, and the other surface as the first surface 211; the protruding part 21 further includes a side wall 213 for clamping the movable plate 4, one end of the side wall 213 being connected to the first surface 211, and the other end being connected to the second surface 212. The ultra-thin hinge arm 3 of the embodiment includes a first branch arm 31, a second branch arm 32, and a third branch arm 33, wherein the first branch arm 31 and the second branch arm 32 are hingedly connected, one end of the first branch arm 31 away from the second branch arm 32 being hingedly connected to the hinge cup 1, and one end of the second branch arm 32 away from the first branch arm 31 being hingedly connected to the movable plate 4; the third branch arm 33 is located below the first branch arm 31 and the second branch arm 32 in the Z-axis direction, i.e., the projection of the third branch arm 33 along the third direction at least partially overlaps the first branch arm 31 and the second branch arm 32; specifically, one end of the third branch arm 33 is hingedly connected to the second branch arm 32, and the other end is hingedly connected to the hinge cup 1, so as to enhance the connection stability of the hinge cup 1 and the second branch arm 32.

[0048] The second branch arm 32 includes an integrally formed arm head 321 and an arm body 322, the arm body 322 being hingedly connected to the movable plate 4, and the arm head 321 being hingedly connected to the first branch arm 31; the arm head 321 plays a role of limiting the hinge cup 1 when the door body is closed relative to the cabinet, i.e., when the hinge cup 1 is retracted relative to the base 2; the arm head 321 does not abut against the side wall 213 in the first direction, i.e., the arm head 321 is not clamped and limited by the embedded groove 22. As known by those skilled in the art, the size of the arm head 321 in the second direction is positively correlated with the connection stability of the hinge cup 1 and the ultra-thin hinge arm 3; currently, the size of the base 2 and the arm head 321 in the second direction is usually designed to be large on the market, so as to enhance the connection stability of the hinge cup 1 and the ultra-thin hinge arm 3. However, in the embodiment, the size of the arm head 321 in the second direction is irrelevant to 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 in the second direction by the two protruding parts 21; under the condition that the arm head 321 and the arm body 322 do not easily 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 very small, the space occupied by the base 2 in the cabinet is small, and the aesthetic appearance is improved.

[0049] Specifically, the ultra-thin hinge based on the one-piece forming process of the embodiment further includes an adjusting screw 6, which is sequentially provided in the arm body 322 of the second branch arm 32 and the movable plate 4 along the third direction, as shown in Figure 2As shown, the arm body 322 is provided with a first shaft hole 323, the movable plate 4 is provided with a second shaft hole 43, the adjusting screw 6 is sequentially provided with the first shaft hole 323 and the second shaft hole 43 along the third direction, and is threadedly connected with the first shaft hole 323 and riveted with the second shaft hole 43, when the adjusting screw 6 is axially rotated, the engagement position of the adjusting screw 6 and the screw thread of the arm body 322 is changed, the relative position of the second supporting arm 32 and the movable plate 4 in the third direction can be adjusted, that is, the angle of the ultra-thin hinge arm 3 relative to the movable plate 4 is adjusted; preferably, even if the ultra-thin hinge arm 3 and the movable plate 4 are adjusted to the maximum 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, which ensures the appearance of the hinge in the embodiment. The connection mode of the hinge arm and the base commonly seen in the market today is that the two sides of the hinge arm are provided on the two ends of the base in the second direction, when the relative angle of the hinge arm and the base in the third direction is adjusted, most of the hinge arm will be suspended relative to the base, that is, as the included angle of the hinge arm and the base increases, the area of the projection of the hinge arm along the second direction coinciding with the base becomes smaller and smaller, the contact area decreases, the pressure increases, and the sinking of the door body relative to the cabinet body is aggravated. The ultra-thin hinge provided in the embodiment not only has a more beautiful appearance, but also avoids cantilevering between the hinge arm 3 and the base 2 due to the setting of the embedded groove of the base, ensures that the center of gravity of the hinge arm 3 is located in the embedded groove 22, avoids the increase of torque, and even if used for a long time, the connection between the hinge arm 3 and the cabinet body will not be loose, deviated and fallen off, greatly prolonging the service life.

[0050] Specifically, as shown in the drawings, Figure 2 The movable plate 4 is provided with a pair of positioning side plates 41, one side of the positioning side plate 41 extends along the first direction and is used for abutting against the arm body 322 of the second supporting arm 32, and the other side of the positioning side plate 41 extends along the third direction, the positioning side plate 41 is provided with a second limiting hole 46, and the corresponding position of the arm body 322 is provided with a first limiting hole 325, the first limiting hole 325 and the second limiting hole 46 are sequentially penetrated by the pin shaft 42, so that the second supporting arm 32 can rotate relative to the movable plate 4 and be angle-adjusted in the third direction; in order to ensure that the movable plate 4 and the base 2 will not be separated in the third direction, the sliding groove 214 extending along the first direction is formed on the side wall 213 in the embodiment, and the pin shaft 42 penetrates the sliding groove 214 in addition to the first limiting hole 325 and the second limiting hole 46, the sliding groove 214 extends along the first direction, and the pin shaft 42 is slidingly connected to the sliding groove 214, preferably, the sliding groove 214 is configured as a waist-shaped groove, the two ends of the waist-shaped sliding groove 214 in the first direction are configured as semicircles, and the size of the semicircle is matched with the size of the pin shaft 42; as shown in the drawings, Figure 1 In order to facilitate assembly, the sliding groove 214 is also formed on at least one side of the base 2 in the second direction in the embodiment, and the projection of the sliding groove 214 along the second direction coincides with the sliding groove 214 on the side wall 213; Figure 2As shown, the ultra-thin hinge of the embodiment further comprises a first adjusting member 5, the movable plate 4 is provided with a third shaft hole 45 at one end of the movable plate 4 away from the second branch arm 32 in the first direction, the first adjusting member 5 penetrates the third shaft hole 45 and is riveted with the second surface 212 of the base 2, and is used for adjusting the relative position of the movable plate 4 and the base 2 in the first direction, such as Figure 4 As shown, when the first adjusting member 5 is rotated in the axial direction, the movable plate 4 can move relative to the base 2 in the first direction, thereby driving the ultra-thin hinge arm 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 the door body is installed, and achieve the best alignment effect.

[0051] In an optional embodiment, as shown, Figure 2 As shown, the ultra-thin hinge based on the one-piece forming process further comprises a chassis 8, the chassis 8 is provided with a pair of sliding blocks at both ends in the first direction, for the sake of distinction, the two pairs of sliding blocks are defined as a first sliding block 81 and a second sliding block 82, the first sliding block 81 and the second sliding block 82 are both configured as concave shapes in a cross section perpendicular to the second direction, used for clamping connection to the second surface 212 of the base 2 and capable of sliding relative to the second surface 212, the chassis 8 is provided with a fourth shaft hole 83, the movable plate 4 is provided with a second through hole 44, the second through hole 44 can expose a plurality of through holes on the second surface 212 in the third direction, the arm body 322 of the second branch arm 32 is provided with a first through hole 324 at a corresponding position, the second adjusting member 7 is arranged at the first through hole 324, the second adjusting member 7 penetrates the first through hole 324 and the second through hole 44 and the through holes at the corresponding positions on the second surface 212, and is finally riveted with the fourth shaft hole 83. Preferably, the second adjusting member 7 and the first adjusting member 5 are both configured as eccentric pins. It should be noted that the eccentric pin is a special bolt with an eccentric structure, the axis of the 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 is rotated, the threaded shaft is limited to rotate in the threaded hole, and the nut rotates with the threaded shaft in an offset manner, thereby pushing the structure abutting against the nut to move, so as to realize the displacement and adjustment functions; as shown, Figure 4 As shown, when the second adjusting member 7 is rotated in the axial direction, the position of the chassis 8 relative to the second surface 212 in the second direction can be adjusted. In this way, 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 reach the best alignment state, and the smoothness and sealing performance of opening and closing are ensured.

[0052] As an optional implementation, the ultra-thin hinge of the embodiment further comprises a damping assembly arranged in the hinge cup 1, used for providing a damping force when the ultra-thin hinge arm 3 rotates relative to the hinge cup 1; Figure 5 The ultra-thin hinge shown is different from the ultra-thin hinge shown in Figure 1 The difference between the ultra-thin hinge shown and the ultra-thin hinge shown in Figure 5A pair of fixing parts are respectively arranged on both sides of the hinge cup 1 along the second direction, and the hinge cup 1 and the door body can be fixed by screwing, Figure 1 The super-thin hinge shown is generally applicable to wooden door bodies, Figure 5 The super-thin hinge shown is generally applicable to aluminum door bodies or door bodies made of other metal materials, and such a transformation also falls within the protection scope of the utility model.

[0053] The adjusting screw 6, the first adjusting part 5 and the second adjusting part 7 can be respectively used for adjusting the relative displacement of the super-thin hinge based on the one-piece forming process in three directions in a three-dimensional space, so that the super-thin hinge based on the one-piece forming process can avoid end face unevenness, obvious gaps and other problems after installation as much as possible, the appearance is improved, and the service life of the super-thin hinge based on the one-piece forming process is prolonged.

[0054] Embodiment two

[0055] This embodiment is a simplified implementation based on embodiment one, and the repeated parts will not be described here.

[0056] Compared with embodiment one, the chassis 8 is removed in this embodiment, and accordingly, the second adjusting part 7 is also not required; in order to ensure that the super-thin hinge of this embodiment still has the relative displacement in three directions in a three-dimensional space, that is, the base 2 still has the function of adjusting the position in the second direction, the first surface 211 and the second surface 212 of the convex part 21 are both provided with screw passing holes, and the screw passing hole on the second surface 212 of the base 2 is changed from a regular circle to a waist shape, based on the shape characteristics of the waist-shaped hole: the waist-shaped hole is composed of two semicircles with the same radius and a middle parallel straight line segment, forming a symmetrical long and narrow hole. In this embodiment, the extension direction of the parallel straight line is parallel to the second direction, please refer to Figure 4 , Figure 4As can be seen from the drawings, the first surface 211 of the base is provided with two pairs of circular accommodating holes. In this embodiment, the second surface 212 is also provided with two pairs of accommodating holes, and the accommodating holes of the second surface 212 are configured as waist-shaped holes. The circular accommodating holes correspond to the waist-shaped holes in the third direction. It can be understood that, in order to facilitate the screw to penetrate the first surface, the head of the screw is arranged to abut against the second surface. After being tightened, the head of the screw limits the base. The projection of the circular accommodating hole in the third direction is larger than the projection of the waist-shaped hole, that is, the circumferential dimension of the circular accommodating hole is larger than the circumferential dimension of the waist-shaped hole. At this time, when adjusting the position of the ultra-thin hinge in the second direction, the installer can make the screw partially penetrate the waist-shaped hole and engage with the threaded portion on the cabinet body. The head of the screw has a gap with the cabinet body to ensure that the base can move relative to the cabinet body in the second direction. After being moved to the specified position, the screw is tightened, and one side of the second surface 212 abuts against the head of the screw, and the other side abuts against the cabinet body. The pressure applied to the second surface 212 by the thread and the screw head is greater than the gravity of the hinge itself, preventing the hinge from deviating.

[0057] Embodiment three

[0058] The difference between this embodiment and embodiment one is only the structure of the ultra-thin hinge arm 3. The repeated parts will not be described here.

[0059] Specifically, please refer to Figure 6 and Figure 7 , the span of the second arm 32 of the ultra-thin hinge arm 3 is different, that is, Figure 6 and Figure 7 The height of the second arm 32 in the third direction is different to adapt to the door body of different thicknesses. It can be understood that the implementation of this embodiment is not limited to the two implementation modes of Figure 6 and Figure 7 The bending angle between the arm head 321 and the arm body 322 can also be changed, that is, the size of the second arm 32 in the first direction and the third direction is changed. Such implementation also falls within the protection scope of the present application to expand the application range of the ultra-thin hinge.

[0060] In summary, the application provides an ultrathin hinge based on an integrated molding process, the ultrathin hinge arm 3 is hingedly connected with the movable plate 4, the movable plate 4 is clamped by the base 2 which is integrally formed, and can slide relative to the base 2 to adjust the relative position of the door body and the hinge, and then adjust the relative position of the door body and the cabinet body, compensate for installation errors, and make the door body and the cabinet body reach the best alignment state, the base 2 of the ultrathin hinge based on the integrated molding process of the application has simple production process and low processing cost, and is convenient for mass production; and since the base 2 is separately arranged with the movable plate 4 and the ultrathin hinge arm 3, manufacturers can mass-produce the base 2 through the integrated molding process, and then produce corresponding number or shape of the ultrathin hinge arm 3 and the movable plate 4 according to the use scene after receiving a specified number of orders, and finally assemble and ship, which greatly shortens the working hours.
