Description

TECHNICAL FIELD

[0001] The present application relates to a hinge assembly for furniture, in particular a hinge assembly for furniture components. BACKGROUND

[0002] At present, the structure of the existing hinge mainly includes a hinge head, a hinge arm and a base. The hinge head and the base are respectively installed on the cabinet door and the cabinet body in sequence. Since the structure of the hinge itself for adjusting and installing position is single, it is difficult to meet the use requirements. Therefore, the installation precision and position precision of the existing hinge are required to be high. When the installation position deviates, the cabinet door and the cabinet body cannot be installed at the predetermined position, which makes the installation difficult, prolongs the working cycle and reduces the working efficiency. For this reason, part of the hinge is provided with an adjusting device. The hinge arm is adjusted in height in the upward and downward direction or adjusted in the front and rear direction or adjusted in the left and right direction relative to the base through the adjusting device. However, the process of the hinge arm of the existing hinge adjusting in height in the upward and downward direction and adjusting in the left and right direction relative to the base affects each other. For example, the height adjusting screw of the adjusting device can only adjust the front end of the base upward or downward. When the front end of the base is adjusted upward to the specified position, the front end of the base is inclined to the rear end and forms an angle with the hinge arm. It can also be understood that the angle between the base and the hinge arm changes in the adjusting process of the height adjusting screw. Therefore, the phenomenon that the cabinet door cannot be closed in place or closed flatly easily occurs, such as the gap between the closed side of the cabinet door and the cabinet body. Therefore, the front and rear adjusting screws of the base and the hinge arm need to be adjusted to make the cabinet door and the cabinet body installed at the predetermined position. It is easy to cause the incorrect height adjustment and front and rear adjustment of the base and the hinge arm, which makes the adjustment difficult.

[0003] In addition, the Chinese patent No. CN204691509U discloses a buffer hinge with parallel adjusting device, which comprises a hinge cup, a swing arm, a hinge base and a base assembly. The hinge cup, the swing arm and the hinge base are sequentially hinged, and the base assembly is installed on the hinge base. The hinge base is provided with a height adjusting assembly which can integrally control the parallel movement height of the base assembly relative to the hinge base. The height adjusting assembly penetrates the hinge base and is buckled on the base assembly. Specifically, the height adjusting assembly comprises a first height adjusting screw and a second height adjusting screw which are respectively installed on the hinge base. By matching the structure of the first height adjusting screw and the second height adjusting screw of the height adjusting assembly, the hinge base can be moved horizontally upward or downward to adjust the height, so as to ensure that the hinge base can be smoothly adjusted in the front and rear installation position relative to the base assembly. However, first, the height adjustment of the hinge base needs to be realized by the first height adjusting screw and the second height adjusting screw, and the adjustment process is relatively troublesome and difficult. Generally, the operator adjusts one adjusting screw first and then adjusts the other adjusting screw. In the adjustment process, the base assembly actually rotates and swings forward and backward relative to the hinge base, and the base assembly does not maintain horizontal relative to the hinge base during the entire adjustment process. Second, when adjusting the height of the hinge base, the front and rear adjusting screws need to be operated, that is, the height adjusting screw cannot be adjusted alone to complete the height adjustment, and the height adjusting screw and the front and rear adjusting screws affect each other during the adjustment process. Third, when adjusting the height of the hinge base, the front and rear adjusting screws on the hinge base need to be loosened first, which causes the hinge base to be easily moved in the front and rear directions, the position is offset in the front and rear directions, the adjustment difficulty is increased, and the height adjustment of the hinge base is more troublesome. In addition, this scheme cannot produce positive effects while increasing the adjustment steps.

[0004] For another example, the Chinese patent No. CN10701023A discloses a door hinge arm with quick adjustment and installation function, which comprises an inner arm and an outer arm. An adjusting mechanism and a movement adjusting device are arranged between the inner arm and the outer arm. The adjusting mechanism is used for adjusting the inclination angle between the outer arm and the inner arm. The movement adjusting device is used for automatically moving the outer arm forward and backward on the inner arm when the inclination angle between the outer arm and the inner arm changes, so as to form relative movement between the outer arm and the inner arm, and adjust the installation position of the door installation adjusting hinge arm. The door hinge can be adjusted by the movement adjusting device, and the installation position of the door can be quickly adjusted. However, the adjusting mechanism changes the inclination angle between the outer arm and the inner arm during the adjustment process, so as to change the minimum closing angle and the maximum opening angle of the hinge cup (hinge head) relative to the base, that is, the closing angle and the opening angle of the door on the furniture are changed, which affects the opening and closing experience of the user.

[0185] The hinge in the prior art, and the "buffer hinge with parallel adjustment device" disclosed in Chinese Patent No. CN204691509U and the "door hinge arm with quick adjustment and installation function" disclosed in Chinese Patent No. CN10701023A have the technical problems as described in the background art.

[0186] Example 1

[0187] As shown in Figures 1 to 63 The present embodiment 1 discloses a hinge assembly for furniture, comprising a first body 1, a hinge head 2 and a base device 3, the hinge head 2 is rotatably connected with the first body 1, the hinge head 2 is used for connecting a second member 200; the base device 3 is used for connecting a first member 100; the base device 3 comprises at least one first adjustment assembly 31 and at least one second adjustment assembly 32; wherein the first adjustment assembly 31 is provided with at least one first adjustment part 33, when the first adjustment part 33 is adjusted alone, the first body 1 can only realize translation and lifting along the up-down direction relative to the first adjustment assembly 31, so that the first body 1 can only realize translation and lifting along the up-down direction relative to at least part of the base device 3; the second adjustment assembly 32 is provided with a second adjustment part 34, when the second adjustment part 34 is adjusted alone, the first body 1 can only move along the front-back direction relative to at least part of the base device 3.

[0188] The first component 100 and the second component 200 can be component plates of a furniture product, and can be made of wood, plastic, metal or other synthetic materials. The first component 100 can be a cabinet door of a cabinet body, and the second component 200 can be a cabinet side plate of the cabinet body. The first component 100 and the second component 200 are relatively rotatable through the hinge assembly of the present embodiment 1.

[0189] It can be understood that when the first adjusting part 33 is adjusted alone, the first body 1 is only translated and lifted in the up-down direction (the up-down direction can generally be the height direction) relative to the first adjusting assembly 31, that is, in the up-down direction, the height distance moved by each part of the first body 1 relative to the base device 3 in a unit time period is the same, so that the first body 1 will not be tilted or moved in the left-right direction or the front-back direction relative to the first adjusting assembly 31 and / or the second adjusting assembly 32, thereby ensuring that the degree of freedom of the first body 1 in the up-down direction is changed only, and the position adjustment of the first body 1 relative to the base device 3 in the up-down direction is realized, so that the second component 200 is only adjusted in the up-down direction relative to the first component 100. When the second adjusting part 34 is adjusted alone, at least part of the first body 1 is only moved in the front-back direction relative to the base device 3, that is, in the front-back direction, the front-back distance moved by each part of the first body 1 relative to the base device 3 in a unit time period is the same, so that the first body 1 will not be moved in the up-down direction or the left-right direction relative to the base device 3, thereby ensuring that the degree of freedom of the first body 1 in the front-back direction is changed only, and the position adjustment of the first body 1 relative to the base device 3 in the front-back direction is realized. By adjusting the first body 1 to be translated and lifted in the up-down direction relative to the base device 3 through the first adjusting part 33 and adjusting the first body 1 to be moved in the front-back direction relative to the base device 3 through the second adjusting part 34, it is ensured that the first body 1 does not affect or interfere with each other during the up-down direction adjustment and the front-back direction adjustment, the adjustment difficulty is reduced, and the accuracy and convenience of the position adjustment of the cabinet door relative to the cabinet body are improved.

[0190] It should be noted that the term "adjusted alone" illustrates that when the first adjusting part 33 is adjusted, the first body 1 is only moved in the up-down direction relative to the base device 3, and when the second adjusting part 34 is adjusted, the first body 1 is only moved in the front-back direction relative to the base device 3;

[0191] It also indicates that when the first adjusting part 33 is adjusted, the first component 100 and the second component 200 will not be displaced in other directions except the up-down direction of the connecting surface relative to the base device 3, or when the second adjusting part 34 is adjusted, the first component 100 and the second component 200 will not be displaced in other directions except the front-back direction of the connecting surface relative to the base device 3;

[0192] It also indicates that when adjusting the vertical direction of the first main body 1 relative to the base device 3, only the first adjustment part 33 needs to be adjusted, and the second adjustment part 34 does not need to be adjusted; or when adjusting the front-back direction of the first main body 1 relative to the base device 3, only the second adjustment part 34 needs to be adjusted, and the first adjustment part 33 does not need to be adjusted.

[0193] Furthermore, the statements "the first main body 1 will not tilt or move relative to the first adjusting component 31 and / or the second adjusting component 32 in the left-right or front-back direction" or "the first main body 1 will not move relative to the base device 3 in the up-down or left-right direction" are descriptive of the relative position in front-back and up-down directions, and do not imply that there can be absolutely no error or deviation. In actual production and installation, dimensional deviations often occur between components. For example, when the first adjusting component 31 and the first main body 1 or the second adjusting component 32 are adjusted up-down, if one end point on the first adjusting component 31 and the other end point on the first main body 1 or the second adjusting component 32 are displaced within 15 degrees in the front-back or left-back direction due to adjustment, we still consider this to be a production and installation error, and it is still within the scope of protection of this patent; the same applies to the adjustment process of the second adjusting component 32.

[0194] It should also be noted that, for example Figures 1 to 3 As shown, in this embodiment 1, the vertical direction of the hinge assembly refers to the direction in which the side of the base device 3 connected to the first component 100 faces the base device 3. When the first component 100 is a cabinet side panel and the second component 200 is a cabinet door, the vertical direction of the hinge assembly is the direction in which the cabinet door adjusts left and right relative to the cabinet body (i.e., Figure 2 or Figure 3 (Left and right directions). The front-back direction of the hinge assembly refers to the direction in which the hinge head 2 faces the first main body 1. When the first component 100 is a cabinet side panel and the second component 200 is a cabinet door, the front-back direction of the hinge assembly is the direction in which the cabinet door adjusts forward and backward relative to the cabinet body. The left-right direction of the hinge assembly refers to the direction that is perpendicular to both the up-down and front-back directions. When the first component 100 is a cabinet side panel and the second component 200 is a cabinet door, the left-right direction of the hinge assembly is the direction in which the cabinet door adjusts up and down relative to the cabinet body.

[0195] This embodiment 1 does not limit the positional relationship between the first main body 1, the first adjustment component 31, and the second adjustment component 32. In some embodiments, such as Figures 4 to 40 , Figures 56 to 61 As shown, at least a portion of the first main body 1 is located above the base device 3. The first main body 1 and the first adjustment component 31 or the second adjustment component 32 are connected from top to bottom. For example, the first main body 1, the first adjustment component 31, and the second adjustment component 32 are arranged sequentially from top to bottom, or the first main body 1, the second adjustment component 32, and the first adjustment component 31 are arranged sequentially from top to bottom. In other embodiments, such asFigures 41 to 46 、 Figures 50 to 52 As shown in FIG. 1, at least a part of the base device 3 is above the first body 1, and the first adjusting assembly 31 or the second adjusting assembly 32 is connected to the first body 1 from top to bottom, for example, the first adjusting assembly 31, the second adjusting assembly 32 and the first body 1 are arranged in sequence from top to bottom, or the second adjusting assembly 32, the first adjusting assembly 31 and the first body 1 are arranged in sequence from top to bottom. Figures 47 to 49 、 Figures 53 to 55 As shown in FIG. 1, at least a part of the base device 3 is above the first body 1, and the first adjusting assembly 31 or the second adjusting assembly 32 is connected to the first body 1 from top to bottom, for example, the first adjusting assembly 31, the second adjusting assembly 32 and the first body 1 are arranged in sequence from top to bottom, or the second adjusting assembly 32, the first adjusting assembly 31 and the first body 1 are arranged in sequence from top to bottom.

[0196] In some embodiments, the first adjusting assembly 31 is provided with a first positioning part 4, and the first body 1 and / or the second adjusting assembly 32 is provided with a second positioning part 5 matched with the first positioning part 4, and the first positioning part 4 and the second positioning part 5 match with each other to limit the freedom of the first body 1 or the second adjusting assembly 32 relative to the first adjusting assembly 31 in the front-rear direction and the left-right direction, so that the first body 1 is allowed to move up and down relative to the first adjusting assembly 31. For example, the second positioning part 5 can be located on the first body 1, and the first adjusting assembly 31 and the first body 1 are matched by the first positioning part 4 and the second positioning part 5 to limit the freedom of the first body 1 relative to the first adjusting assembly 31 in the front-rear direction and the left-right direction, so as to ensure that the first body 1 is allowed to move up and down relative to the first adjusting assembly 31 only in the up-down direction when the first adjusting part 33 is adjusted alone. For another example, the second positioning part 5 can be located on the second adjusting assembly 32, and the first adjusting assembly 31 and the second adjusting assembly 32 are matched by the first positioning part 4 and the second positioning part 5 to limit the freedom of the second adjusting assembly 32 relative to the first adjusting assembly 31 in the front-rear direction and the left-right direction, so as to ensure that the second adjusting assembly 32 is allowed to move up and down relative to the first adjusting assembly 31 only in the up-down direction when the first adjusting part 33 is adjusted alone. In this embodiment, the second adjusting assembly 32 is connected to the first body 1, and the first body 1 is allowed to move up and down relative to the first adjusting assembly 31 only in the up-down direction.

[0197] Further, in some embodiments, in order to make the first positioning part 4 and the second positioning part 5 cooperate to limit the freedom of the first main body 1 or the second adjusting assembly 32 relative to the first adjusting assembly 31 in the front-rear direction and the left-right direction, the side surface of the first positioning part 4 in the front-rear direction and the left-right direction and the side surface of the second positioning part 5 in the front-rear direction and the left-right direction are matched one by one, for example, by abutting or fitting to limit the freedom of the first main body 1 or the second adjusting assembly 32 relative to the first adjusting assembly 31 in the front-rear direction and the left-right direction, so that when the first adjusting part 33 is driven alone, the first main body 1 only realizes translation in the up-down direction relative to the first adjusting assembly 31.

[0198] Further, in some embodiments, as shown in Figures 25 to 28 the first positioning part 4 includes the first adjusting part 33 and the first abutting part 42, and the second positioning part 5 includes the stable part 51 and the second abutting part 52. The first adjusting part 33 is a cylindrical body, and is rotatably arranged on the stable part 51, for example, by riveting or concave-convex fitting or screw fitting, so that the first adjusting part 33 becomes part of the first main body 1 or the second adjusting assembly 32, and rotates relative to the first main body 1 or the second adjusting assembly 32. The side surface of the first adjusting part 33 in the front-rear direction and the left-right direction and the side surface of the stable part 51 in the front-rear direction and the left-right direction are matched one by one, for example, by abutting or fitting to limit the freedom of the first main body 1 or the second adjusting assembly 32 relative to the first adjusting assembly 31 in the front-rear direction and the left-right direction. The first abutting part 42 and the second abutting part 52 abut to limit the rotation of the first adjusting part 33 in the process of rotation, so that only the first adjusting part 33 rotates to make the first main body 1 only realize translation in the up-down direction relative to the first adjusting assembly 31.

[0199] In some embodiments, as shown in Figures 56 to 59As shown, the first adjusting assembly 31 comprises the first left side plate 311 and / or the first right side plate 312, the first main body 1 or the second adjusting assembly 32 comprises the second left side plate 61 and / or the second right side plate 62; the first left side plate 311 and / or the first right side plate 312 is provided with at least one first folding portion (not shown in the figure), the first positioning portion 4 comprises the first folding portion; one end of the first folding portion is connected with the first left side plate 311, one of the left and right sides of the first left side plate 311 is in close contact with one of the left and right sides of the second left side plate 61, the first folding portion passes through the second left side plate 61 and abuts against the other side of the second left side plate 61, the second left side plate 61 and the first folding portion cooperate with each other to limit the movement of the second left side plate 61 in at least one of the left-right direction and the front-rear direction; and / or, one end of the first folding portion is connected with the first right side plate 312, one of the left and right sides of the first right side plate 312 is in close contact with one of the left and right sides of the second right side plate 62, the first folding portion passes through the second right side plate 62 and abuts against the other side of the second right side plate 62, the second right side plate 62 and the first folding portion cooperate with each other to limit the movement of the second right side plate 62 in at least one of the left-right direction and the front-rear direction. Wherein, the position of the first left side plate 311 corresponds to the position of the second left side plate 61, and the position of the first right side plate 312 corresponds to the position of the second right side plate 62, for example, when the first adjusting assembly 31 comprises the first left side plate 311, the second adjusting assembly 32 comprises the second left side plate 61, the first left side plate 311 and the second left side plate 61 abut against each other, and the second left side plate 61 and the first folding portion cooperate with each other to limit the movement of the second left side plate 61 in at least one of the left-right direction and the front-rear direction, thereby limiting the freedom of the first main body 1 or the second adjusting assembly 32 relative to the first adjusting assembly 31 in the front-rear direction and / or the left-right direction, so that the first main body 1 only moves in the up-down direction relative to the first adjusting assembly 31.

[0200] The first folding portion can be a column structure, for example, one end of the first folding portion is inserted into the first left side plate 311 or the first right side plate 312. The first folding portion can be a protrusion or a bump or a block structure, for example, one end of the first folding portion is integrated with the first left side plate 311 or the first right side plate 312. The number of first folding portions can be one or more, for example, the number of first folding portions is at least two, and at least two first folding portions limit the movement of the first adjusting assembly 31 relative to the first main body 1 or the second adjusting assembly 32 in the front-rear direction. For example, there are two first folding portions respectively located at the two ends of the first left side plate 311 or the first right side plate 312 in the front-rear direction, and the two first folding portions respectively cooperate with the second left side plate 61 or the second right side plate 62 to abut against or fit each other, thereby limiting the movement of the first adjusting assembly 31 relative to the first main body 1 or the second adjusting assembly 32 in the front-rear direction.

[0201] In some other implementations, such as Figures 56 to 59 As shown, the first adjustment assembly 31 includes a first left side plate 311 and / or a first right side plate 312, and the first main body 1 or the second adjustment assembly 32 includes a second left side plate 61 and / or a second right side plate 62; the second left side plate 61 and / or the second right side plate 62 are provided with at least one second fold 7, and the second positioning part 5 includes the second fold 7; one end of the second fold 7 is connected to the second left side plate 61, one side of the left and right sides of the second left side plate 61 is close to one side of the left and right sides of the first left side plate 311, and the second fold 7 extends beyond the first left side plate 311 and abuts against the other side of the first left side plate 311. Next, the first left side plate 311 and the second fold 7 cooperate to restrict the movement of the first left side plate 311 in at least one of the left-right and front-back directions; and / or, one end of the second fold 7 is connected to the second right side plate 62, one side of the left and right sides of the second right side plate 62 is abutted against one side of the left and right sides of the first right side plate 312, the second fold 7 extends over the first right side plate 312 and abuts against the other side of the first right side plate 312, and the first right side plate 312 and the second fold 7 cooperate to restrict the movement of the first right side plate 312 in at least one of the left-right and front-back directions. The structure and principle of the second fold 7 are the same as those of the first fold 7 described above, and are omitted here.

[0202] The number of second folds 7 can be one or more, for example, the number of second folds 7 can be at least two, and at least two second folds 7 respectively restrict the first adjusting part 33, the first adjusting component 31, or the second adjusting component 32 and the second adjusting part 34 from moving in the front-back direction. For example, there are two second folds 7 located at the two ends of the second left side plate 61 or the second right side plate 62 in the front-back direction. The two second folds 7 cooperate with the first left side plate 311 or the first right side plate 312 to abut or fit against each other, thereby restricting the first adjusting component 31 from moving in the front-back direction relative to the first body 1 or the second adjusting component 32.

[0203] In some implementations, such as Figures 4 to 33 , Figures 53 to 57 , Figures 60-61As shown, the second adjustment component 32 is connected to the first adjustment component 31, and the first adjustment component 31 is connected to the first main body 1. This embodiment does not limit the positional relationship between the first main body 1, the first adjustment component 31, and the second adjustment component 32, as long as the first main body 1 can move vertically relative to the first adjustment component 31 only in the vertical direction after the first adjustment component 33 is adjusted individually. For example, the first main body 1, the first adjustment component 31, and the second adjustment component 32 can be connected sequentially from top to bottom, or the first main body 1 and the first adjustment component 31 can be connected sequentially from top to bottom, with the first adjustment component 31 located inside the second adjustment component 32, or the second adjustment component 32, the first adjustment component 31, and the first main body 1 can be connected sequentially. By adjusting the first adjustment component 33 individually, the first main body 1 can move vertically relative to the first adjustment component 31 only in the vertical direction.

[0204] Furthermore, in some implementations, such as Figures 4 to 21 As shown, the second adjustment assembly 32 also includes a connecting component 325. The connecting component 325 can be composed of a single component or at least two components connected to each other in a detachable or non-detachable manner, without limitation. At least a portion of the connecting component 325 is fixedly connected to the first component 100, for example, by bolts or screws. The first adjustment assembly 31 includes a fourth body 314. The second adjustment part 34 connects the connecting component 325 and the fourth body 314. When the second adjustment part 34 is adjusted alone, the fourth body 314 can move relative to the connecting component 325 in the front-back direction. A portion of the second adjustment part 34 can be, for example, an eccentric part or a plate-like body in the shape of a Loehr's triangle. Another portion of the second adjustment part 34 is rotatably disposed on the connecting component 325. The fourth body 314 has a mating part. During the rotation of the second adjustment part 34 relative to the connecting component 325, it drives the fourth body 314 to slide relative to the connecting component 325 in the front-back direction, thereby moving the fourth body 314 relative to the connecting component 325 in the front-back direction. For example, the second adjusting part 34 is a fastener with external threads, and a groove extending in the front-back direction is formed on the fourth body 314. The second adjusting part 34 passes through the groove and is threadedly connected to the connecting member 325. When the second adjusting part 34 and the fourth body 314 are relatively loosened, the fourth body 314 and the connecting member 325 can move in the front-back direction.

[0205] In some embodiments, the first adjustment part 33 is connected to the fourth body 314 and the first body 1. When the first adjustment part 33 is adjusted alone, the first body 1 can move up and down relative to the fourth body 314 only in the vertical direction. Thus, the first body 1 can move up and down relative to the connecting part 325 only in the vertical direction, thereby enabling the first body 1 to move up and down relative to at least a part of the base device 3 only in the vertical direction.

[0206] Specifically, in some embodiments, the first adjusting part 33 is a cylindrical structure, at least a part of the outer side wall or the inner side wall of which is a threaded structure, one end of the first adjusting part 33 is threadedly connected with the first main body 1, the other end of the first adjusting part 33 is connected with the fourth main body 314, or one end of the first adjusting part 33 is threadedly connected with the fourth main body 314, and the other end of the first adjusting part 33 is connected with the first main body 1; when the first adjusting part 33 is driven to rotate relative to the fourth main body 314, the first main body 1 can only move in the up-down direction relative to the fourth main body 314 to realize the lifting, so that the first main body 1 can only move in the up-down direction relative to the connecting part 325 to realize the lifting. Wherein, the first adjusting part 33 is matched with the stable part 51 in the front-rear direction and the left-right direction one by one to limit the freedom of the first main body 1 or the second adjusting assembly 32 in the front-rear direction and the left-right direction relative to the first adjusting assembly 31.

[0207] In some embodiments, the first main body 1 comprises a connecting plate 11, a left side plate 12 and a right side plate 13, the connecting plate 11, the left side plate 12 and the right side plate 13 are enclosed to form a mounting groove 14, wherein the connecting plate 11, the left side plate 12 and the right side plate 13 can be formed into an integrated structure by a bending process or a casting process; at least a part of the fourth main body 314 is arranged in the mounting groove 14 or at least a part of the fourth main body 314 is arranged below the first main body 1, at least a part of the connecting part 325 is arranged in the mounting groove 14 or at least a part of the connecting part 325 is arranged below the fourth main body 314, at least one of the left side and the right side of the fourth main body 314 is tightly attached to one of the outer side or the inner side of the mounting groove 14, so that in the process of adjusting the first adjusting part 33 alone, the left side or the right side of the fourth main body 314 is limited by the outer side or the inner side of the mounting groove 14 to prevent the first main body 1 from moving in the left-right direction relative to the fourth main body 314 or the connecting part 325, so that the first main body 1 can only move in the up-down direction relative to the connecting part 325 to realize the lifting.

[0208] In some embodiments, the first main body 1 comprises a connecting plate 11, a left side plate 12 and a right side plate 13, the connecting plate 11, the left side plate 12 and the right side plate 13 are enclosed to form a mounting groove 14; at least a part of the connecting part 325 can be arranged in the mounting groove 14 or at least a part of the connecting part 325 is arranged below the first main body 1; and at least one of the left side and the right side of the connecting part 325 is tightly attached to one of the outer side or the inner side of the mounting groove 14, so that in the process of adjusting the first adjusting part 33 alone, the left side or the right side of the connecting part 325 is limited by the outer side or the inner side of the mounting groove 14 to prevent the first main body 1 from moving in the left-right direction relative to the connecting part 325, so that the first main body 1 can only move in the up-down direction relative to the connecting part 325 to realize the lifting.

[0209] In some embodiments, as shown in FIG. 1, the first adjusting assembly 31 is connected with the second adjusting assembly 32, and the second adjusting assembly 32 is connected with the first body 1. The present embodiment does not limit the positional relationship of the first body 1, the first adjusting assembly 31 and the second adjusting assembly 32. The first body 1 is connected with the first adjusting assembly 31 through the second adjusting assembly 32. When the first adjusting part 33 is adjusted alone, the first body 1 can only move in the up-down direction relative to the first adjusting assembly 31. Figures 34 to 52

[0210] Further, in some embodiments, as shown in FIG. 1, the second adjusting assembly 32 further comprises a fifth body 324, and the first adjusting assembly 31 further comprises a fourth body 314. At least a part of the fourth body 314 can be fixedly connected with the first member 100, for example, the fourth body 314 is fastened on the first member 100 by means of bolts or screws. The fifth body 324 can move in the up-down direction relative to the fourth body 314, so that the first body 1 can move in the up-down direction relative to the fourth body 314, thereby enabling the first body 1 to move in the up-down direction relative to at least a part of the base device 3. Figures 36 to 38

[0211] In some embodiments, when the second adjusting part 34 is adjusted alone, the first body 1 can only move in the front-back direction relative to the fifth body 324, so that the first body 1 can only move in the front-back direction relative to the fourth body 314.

[0212] Specifically, in some embodiments, the first adjusting part 33 is a cylindrical structure, and at least a part of the outer or inner side wall thereof is a threaded structure. One end of the first adjusting part 33 is threadedly connected with the fifth body 324, and the other end of the first adjusting part 33 is connected with the fourth body 314, or one end of the first adjusting part 33 is threadedly connected with the fourth body 314, and the other end of the first adjusting part 33 is connected with the fifth body 324. When the first adjusting part 33 is driven to rotate relative to the fourth body 314, the fifth body 324 can move in the up-down direction relative to the fourth body 314, so that the first body 1 can move in the up-down direction relative to the fourth body 314, thereby enabling the first body 1 to move in the up-down direction relative to at least a part of the base device 3. The first adjusting part 33 is, for example, matched with the stabilizing part 51 one by one on the side surfaces in the front-back direction and the left-right direction, so as to limit the degrees of freedom of the first body 1 or the second adjusting assembly 32 in the front-back direction and the left-right direction relative to the first adjusting assembly 31.

[0213] In some embodiments, as shown in FIG. 1, Figures 20 to 21 , Figures 34 to 35 , Figures 38 to 40 , Figures 51 to 52 ​​As shown, the first body 1, and / or the first adjusting assembly 31, and / or the second adjusting assembly 32, and / or between the first body 1 and the second adjusting assembly 32, and / or between the first adjusting assembly 31 and the second adjusting assembly 32, and / or between the first adjusting assembly 31 and the first body 1, are connected or separated by the dismounting device 10. The dismounting device 10 can be a sliding dismounting device or a pressing dismounting device or other forms of dismounting device, and the specific structure of the dismounting device 10 is a conventional structure in the technical field, for example, the pressing dismounting device 10 includes a button and a spring, one end of the button is provided with a buckle, and the other end of the button is pressed to control the buckling or loosening of the buckle, thereby realizing the connection or separation between the above-mentioned components. The spring is used to drive the pressing piece to automatically reset.

[0214] Further, in some embodiments, the dismounting device 10 is a pressing dismounting device, and the first body 1 is formed with an operation hole 16 for controlling the state of connection or separation of the pressing dismounting device by external force. The position of the operation hole 16 is set according to the position of the pressing dismounting device, for example, the operation hole 16 can be located at the top or left side or right side of the first body 1. After the user passes through the operation hole 16 with an external tool such as a screwdriver and acts on the pressing dismounting device, the working state of the pressing dismounting device is adjusted to realize the connection or separation between the above-mentioned components.

[0215] In some embodiments, as shown, Figure 32 The base device 3 includes a third adjusting assembly 35, which is arranged inside the first body 1, and / or inside the first adjusting assembly 31, and / or inside the second adjusting assembly 32, and / or between the first body 1 and the second adjusting assembly 32, and / or between the first adjusting assembly 31 and the second adjusting assembly 32, and / or between the first adjusting assembly 31 and the first body 1, and the third adjusting assembly 35 includes a third adjusting part, when the third adjusting part is adjusted alone, the first body 1 can move in the left-right direction relative to at least part of the base device 3. The structure of the third adjusting part is the same as or similar to that of the second adjusting part 34 of the first embodiment 1, and for details, please refer to the description of the second adjusting part 34, which is omitted here. By adding the third adjusting assembly 35 and the third adjusting part, the three-dimensional adjustment of the hinge assembly of the first embodiment 1 is realized, and the adjustment convenience and installation position accuracy are improved.

[0216] In use, the first member 100 is subjected to its own gravity or the gravity of the second member 200 or after long-term frequent use, the base device 3 may exist on the first member 100 in the left-right direction Position deviation occurs, resulting in position deviation of the hinge assembly. In order to solve this technical problem, as shown, Figures 60 to 63As shown, in some embodiments, the base device 3 comprises at least one adjusting hole 36 for fixing the base device 3 on the first component 100 by a fastener, when the fastener is in a preset state, the base device 3 can move along the left-right direction relative to the fastener; the circumferential wall of the adjusting hole 36 has a front and back extending cross grain part 361, when the fastener is in a locked state, the cross grain part 361 is used to prevent the base device 3 from moving along the left-right direction relative to the fastener; and / or, the base device 3 has a downward extending protruding part 362, when the fastener is in a locked state, the protruding part 362 and the first component 100 are tightly engaged to prevent the base device 3 from moving along the left-right direction relative to the fastener. The number of adjusting holes 36 is one or more, for example, two adjusting holes 36 are respectively arranged at the two ends of the base device 3 along the front-back direction. The cross grain part 361 is formed in an integrated structure with the base device 3, which is prepared by casting or cutting or mold manufacturing process, etc. The cross grain part 361 can be composed of several convex ribs or bosses or convex strips, etc. The fastener is, for example, a screw or a bolt, etc. When the fastener locks the base device 3 on the first component 100, the head of the fastener cooperates with the cross grain part 361 to resist, and uses the cross grain part 361 to generate a resistance to prevent the fastener from moving along the left-right direction, thereby limiting the movement of the base device 3 along the left-right direction on the first component 100. Alternatively, when the fastener is locked on the first component 100, at least a part of the protruding part 362 is embedded in the inside of the first component 100, so that the protruding part 362 and the first component 100 are tightly engaged with each other, thereby limiting the movement of the base device 3 along the left-right direction on the first component 100. In some embodiments, the problem of insufficient bonding force between the fastener, the strip-shaped hole and the first component 100 caused by the easy adjustment of the left-right adjusting strip-shaped hole of the one-word base hinge is overcome.

[0217] In the present embodiment 1, the outer side wall or the inner side wall of the first adjusting part 33 can be at least partially threaded or toothed structure, such as a screw or a bolt or a stud or a screw, etc. external thread, or the first adjusting part 33 is a rack body structure, which can drive the first body 1 to move only along the up-down direction relative to the first adjusting assembly 31 by the tooth body meshing mode.

[0218] Example 2

[0219] The present embodiment 2 discloses a hinge assembly for furniture, which is a further design based on the hinge assembly of the above-mentioned embodiment 1. Specifically, as Figures 22 to 24As shown, the first body 1 of the embodiment 2 comprises a connecting plate 11, a left side plate 12 and a right side plate 13, the left side plate 12 is connected to the left side of the connecting plate 11 and extends downward, the right side plate 13 is connected to the right side of the connecting plate 11 and extends downward, and the connecting plate 11, the left side plate 12 and the right side plate 13 enclose a mounting groove 14. In the projection direction perpendicular to the connecting plate 11, the distance between the edges of the left and right sides of the base device 3 and the edges of the internal projection of the mounting groove 14 is less than 3 mm. It can be understood that the left and right sides of the base device 3 can be located in the internal projection of the mounting groove 14 respectively, or the edges of the left and right sides of the base device 3 respectively slightly protrude from the internal projection of the mounting groove 14, for example, the distance between the edges of the left and right sides of the base device 3 and the internal projection of the mounting groove 14 is 0.5 mm, 1 mm, 1.5 mm, 2 mm, 3 mm, etc. When observing the hinge assembly in the projection direction perpendicular to the connecting plate 11, the exposed area of the left and right side edges of the base device 3 in the first body 1 is very small or almost none, and it is difficult for the user to observe the base device 3 from the outside or only a small part of the base device 3 can be seen, so that the aesthetic appearance is higher. At the same time, compared with the existing hinge, the base device 3 of the present application has smaller volume and area, saves the use of materials as a whole, reduces the process difficulty, thereby reducing the cost, and the smaller base device 3 can save the use of space and provide space utilization.

[0220] In some embodiments, the base device 3 is located in the internal projection of the mounting groove 14 in the projection direction perpendicular to the connecting plate 11. Since the area of the base device 3 is smaller than the area of the connecting plate 11 in the projection direction perpendicular to the connecting plate 11, the base device 3 is located in the internal projection of the mounting groove 14, it is difficult for the user to observe the base device 3 from the outside or only a small part of the base device 3 can be seen, so that the aesthetic appearance is higher; and when the user observes the hinge in the direction perpendicular to the connecting plate 11, the base device 3 is in a completely invisible state, giving the impression of a hinge without a base device 3, making the hinge more beautiful. At the same time, compared with the existing base device 3, the base device 3 of the present application has smaller volume and area, saves the use of materials as a whole, reduces the process difficulty, thereby reducing the cost, and the smaller base device 3 can save the use of space and provide space utilization.

[0221] In some embodiments, when the first body 1 is in the lowest position, the base device 3 is inside the projection of the mounting groove 14 in the projection direction perpendicular to the left plate 12 or the right plate 13. In this case, when the first body 1 is adjusted to the lowest position by adjusting the first adjusting part 33 alone to drive the first body 1 to translate only in the up-down direction relative to the first adjusting assembly 31, the base device 3 is entirely inside the mounting groove 14 and cannot be observed from the left or right direction, giving the impression of a baseless hinge and improving the aesthetics of the hinge assembly.

[0222] In some embodiments, the lower ends of the left plate 12 and / or the right plate 13 form a straight line. The lower ends of the left plate 12 and / or the right plate 13 are level with the lower end of the base device 3, or the base device 3 is entirely inside the mounting groove 14, and the user cannot observe the base device 3 when observing the hinge assembly from a direction perpendicular to the left plate 12 or the right plate 13, i.e., the lower ends of the left plate 12 and / or the right plate 13 form a straight line, improving the aesthetics of the hinge assembly.

[0223] In some embodiments, as shown in Figure 70 The hinge assembly further includes a first connecting piece 81, one end of the first connecting piece 81 being hinged to the hinge head 2 through a first hinge shaft 82, and the other end of the first connecting piece 81 being hinged to the first body 1 through a third hinge shaft 83; the hinge head 2 and the first body 1 are rotationally connected through the first connecting piece 81; wherein the base device 3 has at least two through holes 37 for fasteners to pass through; the axis of the plane formed by the two through holes 37 is not perpendicular to the third hinge shaft 83. Two fasteners pass through the two through holes 37 and are fastened to the inner side of the cabinet, and the two fasteners are arranged diagonally, thereby stably fastening the base device 3 to the cabinet, and the user can hardly observe the base device 3 from the outside or can only see a small part of the base device 3, and two fasteners can usually be used to fix the base device 3 to the cabinet plate, reducing the installation trouble and the number of fasteners, improving the installation firmness of the base device 3, and reducing the installation cost.

[0224] Example 3

[0225] This embodiment 3 discloses a hinge assembly for furniture, which is a further design based on the hinge assembly of embodiment 1. Specifically, as shown in Figures 17 to 19As shown, the first body 1 of the present embodiment 3 comprises a connecting plate 11, a left side plate 12, a right side plate 13 and a rear side plate 15, the left side plate 12 is connected to the left side of the connecting plate 11 and extends downward, the right side plate 13 is connected to the right side of the connecting plate 11 and extends downward, the rear side plate 15 is located at the rear side of the connecting plate 11 and / or the left side plate 12 and / or the right side plate 13 and extends downward, and the connecting plate 11, the left side plate 12, the right side plate 13 and the rear side plate 15 enclose to form a mounting groove 14; wherein one or more of the connecting plate 11, the right side plate 13 and the left side plate 12 are fixedly connected with the rear side plate 15; the distance between the bottom of the rear side plate 15 and the bottom of the left side plate 12 is -3mm to 1mm, and / or the distance between the bottom of the rear side plate 15 and the bottom of the right side plate 13 is -3mm to 1mm. It can be understood that the rear end of the rear side plate 15 is connected with the connecting plate 11, or the rear end of the rear side plate 15 is connected with the right side plate 13, or the rear end of the rear side plate 15 is connected with the left side plate 12, or the rear end of the rear side plate 15 is connected with the connecting plate 11 and the left side plate 12, etc., which are formed by bending process or casting process to form an integrated structure of metal parts, and the overall structural strength is larger, which improves the structural stability. Wherein, the distance between the bottom of the rear side plate 15 and the bottom of the left side plate 12 or the right side plate 13 is -3mm, -2mm, 0mm, 1mm, etc. Since the bottom of the rear side plate 15 and the bottom of the left side plate 12 and / or the right side plate 13 are located at the same horizontal plane or close to the same horizontal plane, the rear side of the rear side plate 15, the rear side of the left side plate 12 and the rear side of the right side plate 13 are not exposed, the rear end of the first body 1 is closed or close to closed through the rear side plate 15, which avoids or reduces the possibility of damage to clothes or scratches on the skin of the human body caused by the rear end of the first body 1 after the clothes touch the rear end of the first body 1, and at the same time, the parts of the hinge assembly are wrapped inside the first body 1, so that the user does not need to see the parts of the hinge assembly from the outside, which improves the overall appearance.

[0226] Further, in some embodiments, the distance between the bottom of the rear side plate 15 and the bottom of the left side plate 12 is -2mm to 1mm, and / or the distance between the bottom of the rear side plate 15 and the bottom of the right side plate 13 is -2mm to 1mm. Further make the bottom of the rear side plate 15 and the left side plate 12 and / or the right side plate 13 located at the same horizontal plane or close to the same horizontal plane, so that the rear end of the first body 1 is closed or close to closed, which effectively avoids or reduces the possibility of damage to clothes or scratches on the skin of the human body caused by the rear end of the first body 1 after the clothes touch the rear end of the first body 1.

[0227] Furthermore, the bottom of the rear panel 15 is on the same horizontal plane as the bottom of the left panel 12, and / or the bottom of the rear panel 15 is on the same horizontal plane as the bottom of the right panel 13. By further aligning the bottom of the rear panel 15 with the left panel 12 and / or the right panel 13 on the same horizontal plane, the rear end of the first body 1 is closed, effectively preventing or reducing the possibility of damage to clothing or scratches to human skin from contact with the rear end of the first body 1.

[0228] Example 4

[0229] This embodiment 4 discloses a hinge assembly for furniture, which is a further design based on the hinge assembly of embodiment 1 described above. Specifically, as follows: Figures 64 to 65 As shown, the hinge assembly of this embodiment 4 further includes a first connector 81 and a second connector 84. One end of the first connector 81 is hinged to the hinge head 2 via a first hinge shaft 82, and the other end of the first connector 81 is hinged to the first body 1 via a third hinge shaft 83. One end of the second connector 84 is hinged to the hinge head 2 via a second hinge shaft 85, and the other end of the second connector 84 is hinged to the first body 1 via a fourth hinge shaft 86. A portion of the second connector 84 is located below the first connector 81. The hinge head 2 and the first body 1 are rotatably connected via the first connector 81 and the second connector 84. The hinge assembly also... It includes at least two first elastic elements 87, which are respectively sleeved on the third hinge shaft 83. Each first elastic element 87 has a first abutting end and a second abutting end. The first abutting end of each first elastic element 87 abuts against the first connecting member 81, and the second abutting end of each first elastic element 87 abuts against the first main body 1 or the fourth hinge shaft 86. The hinge head 2 rotates relative to the first main body 1 through the first connecting member 81 and the second connecting member 84. When the hinge head 2 rotates at a certain angle, the first elastic element 87 drives the hinge head 2 to rotate in the closing direction (the closing direction is the closing direction of the cabinet door relative to the cabinet side panel). Since there are at least two first elastic elements 87 sleeved on the third hinge shaft 83, and the first abutting end of each elastic element abuts against the first connecting member 81 and the second abutting end abuts against the first body 1 or the fourth hinge shaft 86, the hinge head 2 is automatically reset relative to the first body 1 by the joint drive of at least two first elastic elements 87, which increases the automatic reset force on the hinge head 2 and makes the reset effect more stable and reliable. At the same time, at least two first elastic elements 87 can effectively improve the fatigue strength of reset and extend the service life of the hinge assembly.

[0230] It is understood that the first elastic element 87 in this embodiment 4 is, for example, a spring or a torsion spring, and at least two first elastic elements 87 are respectively sleeved on the third hinge shaft 83, jointly driving the hinge head 2 to automatically reset relative to the first body 1.

[0231] In some embodiments, the second abutting end of each first elastic member 87 is close to the left inner wall or the right inner wall of the first body 1. By arranging the first abutting end of the first elastic member 87 at both ends close to the left and right sides of the first body 1 respectively, the position interference between the second abutting end of the first elastic member 87 and other components of the hinge assembly is avoided, the internal space utilization of the first body 1 is improved, and the abutting of the second abutting end of the first elastic member 87 to the first body 1 or the fourth hinge shaft 86 is effectively ensured.

[0232] Further, in some embodiments, as shown in Figure 65 the first abutting end of the two first elastic members 87 is connected integrally, or the second abutting end of the two first elastic members 87 is connected integrally, for example, the first abutting end or the second abutting end of the first elastic member 87 is formed into an integrated structure by welding or casting. When the number of first elastic members 87 is two, and the two first elastic members 87 are arranged symmetrically about an axis, the restoring force of the two first elastic members 87 driving the hinge head 2 is more uniform, further prolonging the service life of the hinge assembly. At the same time, the first abutting end or the second abutting end of the two first elastic members 87 is connected integrally, so that the two first elastic members 87 form a whole, which is beneficial to improve the assembly efficiency, and at the same time ensures the stability of the first elastic member 87 driving the hinge head 2 to reset and enhances the driving force of the first elastic member 87 driving the hinge head 2 to reset.

[0233] In some embodiments, the second abutting end of each first elastic member 87 is located between the second connecting piece 84 and the inner side wall of the first body 1, improving the internal space utilization of the first body 1, and effectively ensuring the abutting of the second abutting end of the first elastic member 87 to the first body 1 or the fourth hinge shaft 86.

[0234] The structure of the hinge assembly of the present embodiment 4 is, for example, a segmental force hinge.

[0235] Further, when the first elastic member 87 is a torsional spring, the wire diameter of the first elastic member 87 is greater than or equal to 2.2 mm. When the hinge head 2 rotates to a certain angle relative to the first body 1, the first elastic member 87 is used to drive the hinge head 2 to move in the closing direction, playing an automatic reset role. The first elastic member 87 with a wire diameter greater than or equal to 2.2 mm can provide stronger and more stable torsional force, thereby improving the stability of the hinge head 2 rotation, or reducing the torsional angle of the spring reset, prolonging the service life of the spring, and thereby prolonging the service life of the hinge.

[0236] Further, when the first elastic member 87 is a torsional spring, the number of turns of the first elastic member 87 is greater than or equal to 8 turns. The first elastic member 87 with a number of turns greater than or equal to 8 turns can provide stronger and more stable torsional force, thereby improving the stability of the hinge head 2 rotation, and prolonging the service life of the spring and the hinge.

[0237] Example 5

[0238] This embodiment 5 discloses a hinge assembly for furniture, which is a further design based on the hinge assembly of embodiment 1 described above. Specifically, as follows: Figures 66 to 67 As shown, the hinge assembly of this embodiment 5 further includes a first connector 81 and a second connector 84. One end of the first connector 81 is hinged to the hinge head 2 via a first hinge shaft 82, and the other end of the first connector 81 is hinged to the first body 1 via a third hinge shaft 83. One end of the second connector 84 is hinged to the hinge head 2 via a second hinge shaft 85, and the other end of the second connector 84 is hinged to the first body 1 via a fourth hinge shaft 86. A portion of the second connector 84 is located below the first connector 81. The hinge head 2 and the first body 1 are connected by the first connector 81 and the second connector 84. Rotary connection; the hinge assembly also includes at least two second elastic elements 88, which are respectively sleeved on the third hinge shaft 83. Each second elastic element 88 has a first abutting end and a second abutting end. The first abutting end of each second elastic element 88 abuts against the first body 1 or the fourth hinge shaft 86, and the second abutting end of each second elastic element 88 abuts against the first hinge shaft 82. The hinge head 2 rotates relative to the first body 1 through the first connecting member 81 and the second connecting member 84. When the hinge head 2 rotates at a certain angle, the second elastic element 88 drives the hinge head 2 to rotate in the closing direction. Since there are at least two second elastic elements 88 sleeved on the third hinge shaft 83, and the first abutting end of each second elastic element 88 abuts against the first body 1 and the second abutting end abuts against the first hinge shaft 82, the hinge head 2 is driven to automatically reset relative to the first body 1 by the at least two second elastic elements 88, which increases the automatic reset force on the hinge head 2 and makes the reset effect more stable and reliable. At the same time, the at least two second elastic elements 88 can effectively improve the fatigue strength of the reset and extend the service life of the hinge assembly.

[0239] It is understood that the second elastic element 88 in this embodiment 5 is, for example, a spring or a torsion spring, with the same structure as the first elastic element 87 in the above embodiment 4.

[0240] Furthermore, in some embodiments, the hinge assembly of this embodiment 5 includes two second elastic elements 88, with the second abutting ends of the two second elastic elements 88 located on the left and right sides of the first connecting member 81, respectively. The two axially symmetrically arranged second elastic elements 88 can more stably and uniformly drive the hinge head 2 to rotate relative to the first body 1 in the closing direction (the closing direction is the closing direction of the cabinet door relative to the cabinet side), further extending the service life of the hinge assembly; at the same time, it avoids positional interference between the second abutting ends of the second elastic elements 88 and other components of the hinge assembly, ensuring smooth hinge connection between the hinge head 2 and the first connecting member 81.

[0241] In some embodiments, the first abutting ends of the two second elastic members 88 are connected integrally, for example, by welding or casting into an integrated structure. The two second elastic members 88 are combined into one whole, which is conducive to improving the assembly efficiency, while ensuring the stability of the second elastic members 88 in driving the hinge head 2 to reset and enhancing the driving force of the second elastic members 88 in driving the hinge head 2 to reset.

[0242] In some embodiments, the first abutting ends of the two second elastic members 88 are respectively located on the left and right sides of the first body 1. The two second elastic members 88 arranged in axial symmetry can more stably and uniformly drive the hinge head 2 to rotate relative to the first body 1 in the closing direction, further prolonging the service life of the hinge assembly; avoiding the first abutting ends of the second elastic members 88 from interfering with other components of the hinge assembly, and improving the utilization rate of the internal space of the first body 1.

[0243] In some embodiments, the second abutting ends of the two second elastic members 88 are connected integrally. The two second elastic members 88 are combined into one whole, which is conducive to improving the assembly efficiency, while ensuring the stability of the second elastic members 88 in driving the hinge head 2 to reset and enhancing the driving force of the second elastic members 88 in driving the hinge head 2 to reset.

[0244] In some embodiments, when the first body 1 rotates relative to the hinge head 2 by a certain angle, the second abutting end of each second elastic member 88 abuts against the second hinge shaft 85, so that the hinge head 2 can be further rotated relative to the first body 1, realizing a one-segment half force structure of the hinge.
