Hinge assembly for furniture Technical Field

[0001] The present invention relates to a hinge assembly for furniture, in particular to a hinge assembly used between furniture components. Background Art

[0002] Currently, the structure of existing hinges mainly includes a hinge head, a hinge arm, and a base. During installation, the hinge head and base are installed on the cabinet door and cabinet body respectively. Since the hinge itself has a simple structure for adjusting the installation position, it is difficult to meet the use requirements. Therefore, the installation accuracy and position accuracy of existing hinges are very high. If the installation position deviates, the cabinet door and cabinet body cannot be installed in the predetermined position, making installation difficult, extending the working cycle, and reducing work efficiency. To this end, some hinges are equipped with an adjustment device, through which the hinge arm can be adjusted in the vertical direction, front-to-back direction, or left-to-right direction relative to the base. However, the existing hinges' vertical and horizontal adjustment of the hinge arm relative to the base interfere with each other. For example, the height adjustment screw of the adjustment 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 tilts toward 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 during the adjustment process of the height adjustment screw, which can easily cause the cabinet door to not close properly or smoothly relative to the cabinet body, such as a gap between the closed side of the cabinet door and the cabinet body. Therefore, it is necessary to adjust the front and back adjustment screws of the base and hinge arm to install the cabinet door and cabinet body in the predetermined position. This makes it easy to make incorrect height adjustments and front and back adjustments of the base and hinge arm, making adjustment difficult.

[0003] In addition, the Chinese patent announcement number CN204691509U discloses a "Buffer Hinge with Parallel Adjustment Device", which includes a hinge cup, a swing arm, a hinge seat and a base assembly. The hinge cup, the swing arm and the hinge seat are hinged in sequence, and the base assembly is installed on the hinge seat. The hinge seat is provided with a height adjustment assembly that can control the parallel movement height of the base assembly relative to the hinge seat as a whole. The height adjustment assembly passes through the hinge seat and is snapped onto the base assembly. Specifically, the height adjustment assembly includes a first height adjustment screw and a second height adjustment screw. The first height adjustment screw and the second height adjustment screw are respectively installed on the hinge seat front and back. By coordinating the structures of the first height adjustment screw and the second height adjustment screw of the height adjustment assembly, the entire hinge seat can be moved horizontally up or down to adjust the height, ensuring that the hinge seat can smoothly adjust the front and rear installation position relative to the base assembly on the horizontal plane. However, first, the height adjustment of the hinge seat needs to be achieved through the first height adjustment screw and the second height adjustment screw. The adjustment process is cumbersome and difficult to adjust. Generally, the operator adjusts one of the adjustment screws first and then adjusts the other adjustment screw. During the adjustment process, the base assembly actually rotates and swings back and forth relative to the hinge seat, and the base assembly is not kept level relative to the hinge seat during the entire adjustment process. Second, when adjusting the height of the hinge seat, it is necessary to operate the front and rear adjustment screws, that is, the height adjustment screw cannot be adjusted alone to complete the height adjustment, and the height adjustment screw and the front and rear adjustment screws affect each other during the adjustment process. Third, when adjusting the height of the hinge seat, it is necessary to loosen the front and rear adjustment screws on the hinge seat first, which makes the hinge seat easy to move incorrectly in the front and rear directions, and the position is offset in the front and rear directions, which increases the difficulty of adjustment, thereby making the height adjustment of the hinge seat more troublesome. In addition, this solution does not produce positive effects while increasing the adjustment steps.

[0004] For another example, the Chinese patent publication number CN10701023A discloses a "door hinge arm with a quick adjustment installation function," which includes an inner arm and an outer arm, wherein an adjustment mechanism and a movable adjustment device are provided between the inner and outer arms, wherein the adjustment mechanism is used to adjust the tilt angle between the outer and inner arms; and the movable adjustment device is used to automatically move the outer arm back and forth on the inner arm when the tilt angle between the outer and inner arms changes, so that the outer arm forms a relative movement between the inner arms, tilting and adjusting the door installation position. The door hinge can be adjusted by moving the adjustment device to achieve quick adjustment of the door installation position. However, during the adjustment process, the adjustment mechanism changes the tilt angle between the outer and inner arms, thereby changing the minimum closing angle and maximum opening angle of the hinge cup (hinge head) relative to the base, that is, changing the closing angle and opening angle of the door on the furniture, affecting the user's door opening and closing experience.

[0005] Summary of the Invention

[0006] In order to solve the technical problems in the above-mentioned existing hinges, in which the independent height adjustment and independent front-back adjustment of the hinge seat relative to the base assembly affect each other, resulting in high adjustment difficulty and trouble, and the change in the door opening and closing angle after the height adjustment, which affects the user experience, the present invention provides a hinge assembly for furniture, comprising:

[0007] A first body and a hinge head, wherein the hinge head is rotatably connected to the first body and is used to connect to a second component;

[0008] A base device, the base device is used to connect the first component; the base device includes at least one first adjustment component and at least one second adjustment component;

[0009] The first adjustment assembly is provided with at least one first adjustment portion. When the first adjustment portion is adjusted alone, the first body can be translated and raised only in the vertical direction relative to the first adjustment assembly, thereby enabling the first body to be translated and raised only in the vertical direction relative to at least a portion of the base device.

[0010] The second adjustment assembly is provided with a second adjustment portion, and when the second adjustment portion is adjusted alone, the first body can move only in the front-to-back direction relative to at least a portion of the base device.

[0011] In some embodiments, a first positioning portion is formed on the first adjustment component, and a second positioning portion that cooperates with the first positioning portion is formed on the first main body and / or the second adjustment component. The first positioning portion and the second positioning portion cooperate with each other to limit the freedom of the first main body or the second adjustment component relative to the first adjustment component along the front-to-back direction and the left-to-right direction, so that when the first adjustment portion is adjusted alone, the first main body can only achieve translation and lifting along the up-down direction relative to the first adjustment component.

[0012] In some embodiments, the side surfaces of the first positioning portion along the front-to-back direction and the left-to-right direction and the side surfaces of the second positioning portion along the front-to-back direction and the left-to-right direction correspond one-to-one to limit the freedom of the first main body or the second adjustment component relative to the first adjustment component along the front-to-back direction and the left-to-right direction, so that the first main body can only be translated and raised along the up-down direction relative to the first adjustment component.

[0013] In some embodiments, the first positioning portion includes the first adjusting portion and a first abutting portion, and the second positioning portion includes a stabilizing portion and a second abutting portion. The first adjusting portion is cylindrical and rotatably disposed on the stabilizing portion. The side surfaces of the first adjusting portion in the front-to-back direction and the left-to-right direction correspond to the side surfaces of the stabilizing portion in the front-to-back direction and the left-to-right direction, so as to limit the degree of freedom of the first body or the second adjusting component relative to the first adjusting component in the front-to-back direction and the left-to-right direction.

[0014] The first abutting portion and the second abutting portion abut against each other to limit the first adjusting portion from driving other components of the first adjusting assembly to rotate relative to the first main body, or the second adjusting assembly to rotate relative to the first adjusting assembly, when the first adjusting portion rotates.

[0015] The number of stabilizing parts is not limited, and the number of stabilizing parts can be one or more. The first adjustment component can also be provided with one or more columns arranged side by side with the first adjustment part. The first positioning part includes the column, and the column and other stabilizing parts cooperate to limit the freedom of the first main body or the second adjustment component relative to the first adjustment component along the front-to-back direction and the left-to-right direction.

[0016] Other technical solutions of the present invention are the same as the technical solutions described in claims 5 to 20 and will not be described in detail here.

[0017] Compared with the prior art, the hinge assembly of furniture of the present invention has at least the following beneficial effects:

[0018] The hinge head is installed on the second component (the second component can be, for example, a cabinet door), and the base device is installed on the first component (the first component can be, for example, a cabinet side panel). Since the base device includes a first adjustment component and a second adjustment component, by separately adjusting the first adjustment part on the first adjustment component, the first main body can be driven to move and lift only in the up and down directions relative to the first adjustment component, and the first main body will not tilt or move in the left and right directions or the front and back directions relative to the first adjustment component or the second adjustment component, so that the first main body can only move and lift in the up and down directions relative to at least a part of the base device, ensuring that the position of the second component relative to the first component is only adjusted in the left and right directions.

[0019] In addition, by separately adjusting the second adjustment portion of the second adjustment assembly, the first body can be driven to move only in the front-to-back direction relative to the base assembly, while the first body will not move in the up-down or left-to-right directions relative to the base assembly, thereby adjusting the position of the second member relative to the first member in the front-to-back direction. By adjusting the first body to move only in the up-down direction relative to the base assembly by the first adjustment portion, and adjusting the first body to move only in the front-to-back direction relative to the base assembly by the second adjustment portion, it is ensured that the first body does not affect or interfere with each other during the up-down and front-to-back adjustment processes, thereby reducing the difficulty of adjustment and improving the accuracy and convenience of adjusting the position of the cabinet door relative to the cabinet body.

[0020] Furthermore, during the adjustment process of the first adjustment part and / or the second adjustment part, the inclination angle of the hinge head relative to the base will not change, that is, within any adjustment range of the first adjustment part and / or the second adjustment part, the minimum closing angle and the maximum opening angle of the hinge head relative to the base device (or the first component) remain unchanged, so that the user's experience will not change due to adjusting the first adjustment part and the second adjustment part when using the first component and the second component.

DETAILED DESCRIPTION

[0062] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0063] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.

[0064] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0065] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0066] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0067] The hinges in the prior art, as well as the "Buffer Hinge with Parallel Adjustment Device" disclosed in Chinese Patent Publication No. CN204691509U and the "Door Hinge Arm with Quick Adjustment and Installation Function" disclosed in Chinese Patent Publication No. CN10701023A, have technical problems as described in the background technology.

[0068] As shown in Figures 1 to 40, this embodiment discloses a hinge assembly for furniture, including a first main body 1, a hinge head 2 and a base device 3, the hinge head 2 is rotatably connected to the first main body 1, and the hinge head 2 is used to connect the second component 200; the base device 3 is used to connect the first component 100; the base device 3 includes at least one first adjustment component 31 and at least one second adjustment component 32; wherein, the first adjustment component 31 is provided with at least one first adjustment part 33, when the first adjustment part 33 is adjusted alone, the first main body 1 can be translated and lifted only in the up and down directions relative to the first adjustment component 31, so that the first main body 1 can be translated and lifted only in the up and down directions relative to at least a part of the base device 3; the second adjustment component 32 is provided with a second adjustment part 34, when the second adjustment part 34 is adjusted alone, the first main body 1 can be moved only in the front and back directions relative to at least a part of the base device 3.

[0069] The first component 100 and the second component 200 can each be a component panel of a furniture product, and can be made of wood, plastic, metal, or other synthetic materials. The first component 100 can be, for example, a cabinet door, and the second component 200 can be, for example, a cabinet side panel. The first component 100 and the second component 200 can achieve relative rotation via the hinge assembly of this embodiment.

[0070] It is understood that when the first adjustment portion 33 is adjusted alone, the first body 1 is translated and raised relative to the first adjustment assembly 31 only in the vertical direction (the vertical direction can generally be the height direction). That is, in the vertical direction, each portion of the first body 1 moves the same height distance relative to the base assembly 3 within a unit time period, so that the first body 1 does not tilt or move relative to the first adjustment assembly 31 and / or the second adjustment assembly 32 in the left-right or front-back direction. This ensures that the first body 1's degree of freedom changes only in the vertical direction, enabling the position of the first body 1 relative to the base assembly 3 to be adjusted in the vertical direction, thereby enabling the position of the second member 200 relative to the first member 100 to be adjusted only in the vertical direction. When the second adjustment portion 34 is adjusted alone, the first body 1 moves only in the front-back direction relative to at least a portion of the base assembly 3. That is, in the front-back direction, each portion of the first body 1 moves the same front-back distance relative to the base assembly 3 within a unit time period, so that the first body 1 does not move in the vertical direction or the left-right direction relative to the base assembly 3. This ensures that the first body 1's degree of freedom changes only in the front-back direction, enabling the position of the first body 1 relative to the base assembly 3 to be adjusted in the front-back direction. The first adjustment part 33 is used to adjust the first main body 1 to move horizontally and vertically relative to the base device 3, and the second adjustment part 34 is used to adjust the first main body 1 to move only in the front-back direction relative to the base device 3, ensuring that the first main body 1 does not affect or interfere with each other during the up-down adjustment and the front-back adjustment process, reducing the difficulty of adjustment and improving the accuracy and convenience of adjusting the position of the cabinet door relative to the cabinet body.

[0071] It should be noted that the term "independent adjustment" generally describes that when the first adjustment portion 33 is adjusted, the first body 1 moves only in the up-down direction relative to the base device 3, and when the second adjustment portion 34 is adjusted, the first body 1 moves only in the front-back direction relative to the base device 3;

[0072] This also indicates that when the first adjustment portion 33 is adjusted, the first member 100 and the second member 200 will not be displaced in any direction except the up-down direction relative to the connection surface of the bottom mounting device 3; or when the second adjustment portion 34 is adjusted, the first member 100 and the second member 200 will not be displaced in any direction except the front-back direction relative to the connection surface of the bottom mounting device 3.

[0073] It also shows that when adjusting the up and down direction of the first main body 1 relative to the base device 3, it is only necessary to adjust the first adjustment part 33, without adjusting the second adjustment part 34 or other components; or when adjusting the front and back direction of the first main body 1 relative to the base device 3, it is only necessary to adjust the second adjustment part 34, without adjusting the first adjustment part 33 or other components.

[0074] In addition, "the first body 1 will not tilt or move in the left-right direction or the front-back direction relative to the first adjustment component 31 and / or the second adjustment component 32" or "the first body 1 will not move in the up-down direction or the left-right direction relative to the base device 3" is intended to describe the relativity of the front-back and up-down positions, and does not mean that there must be absolutely no errors or deviations. In actual production and installation, deviations often occur in the dimensions of components. For example, when the first adjustment component 31 and the first body 1 or the second adjustment component 32 are adjusted up and down, and one end point on the first adjustment component 31 and the other end point on the first body 1 or the second adjustment component 32 are displaced within 15 degrees in the front-back or left-right direction due to adjustment, we still believe that this is a production and installation error and is still within the scope of protection of this patent; the same applies to the situation during the adjustment of the second adjustment component 32.

[0075] It should also be noted that, for example, as shown in Figures 1 to 3, the up-down direction of the hinge assembly of this embodiment refers to the direction in which the side surface where the base device 3 is connected to the first component 100 is facing the base device 3. When the first component 100 is a cabinet side panel and the second component 200 is a cabinet door, the up-down direction of the hinge assembly is the direction in which the cabinet door is adjusted left and right relative to the cabinet body (i.e., the left 'right' direction in Figure 2 or Figure 3). The front-to-back direction of the hinge assembly refers to the direction in which the hinge head 2 is facing 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-to-back direction of the hinge assembly is the direction in which the cabinet door is adjusted front and back relative to the cabinet body. The left-to-right direction of the hinge assembly refers to a direction that is perpendicular to both the up-down direction and the front-to-back direction. When the first component 100 is a cabinet side panel and the second component 200 is a cabinet door, the left-to-right direction of the hinge assembly is the direction in which the cabinet door is adjusted up and down relative to the cabinet body.

[0076] This embodiment does not limit the positional relationship between the first body 1, the first adjustment component 31, and the second adjustment component 32. In some embodiments, as shown in Figures 4 to 25 and Figures 35 to 40, at least a portion of the first body 1 is located above the base device 3, and the first body 1 and the first adjustment component 31 or the second adjustment component 32 are connected from top to bottom. For example, the first body 1, the first adjustment component 31, and the second adjustment component 32 are arranged in sequence from top to bottom, or the first body 1, the second adjustment component 32, and the first adjustment component 31 are arranged in sequence from top to bottom. In other embodiments, as shown in Figures 26 to 29 and Figures 50 to 52, at least a portion of the base device 3 is located above the first body 1, and the first adjustment component 31 or the second adjustment component 32 are connected to the first body 1 from top to bottom. For example, the first adjustment component 31, the second adjustment component 32, and the first body 1 are arranged in sequence from top to bottom, or the second adjustment component 32, the first adjustment component 31, and the first body 1 are arranged in sequence from top to bottom. In some other embodiments, as shown in Figures 30 to 31 and Figures 33 to 34, at least a portion of the base device 3 is located on the side of the first body 1, and the first adjustment component 31 or the second adjustment component 32 and the first body 1 are connected in the left-right direction or the right-left direction. For example, the first adjustment component 31, the second adjustment component 32 and the first body 1 are arranged in sequence from left to right, or the second adjustment component 32, the first adjustment component 31 and the first body 1 are arranged in sequence from left to right.

[0077] In some embodiments, a first positioning portion 4 is formed on the first adjustment component 31, and a second positioning portion 5 that cooperates with the first positioning portion 4 is formed on the first body 1 and / or the second adjustment component 32. The first positioning portion 4 and the second positioning portion 5 cooperate with each other to limit the freedom of the first body 1 or the second adjustment component 32 in the front-to-back direction and the left-to-right direction relative to the first adjustment component 31, thereby allowing the first body 1 to translate and rise and fall in the vertical direction relative to the first adjustment component 31. For example, the second positioning portion 5 can be located on the first body 1, and the first adjustment component 31 and the first body 1 cooperate with each other through the first positioning portion 4 and the second positioning portion 5 to limit the freedom of the first body 1 in the front-to-back direction and the left-to-right direction relative to the first adjustment component 31, ensuring that when the first adjustment portion 33 is adjusted alone, the first body 1 can only translate and rise and fall in the vertical direction relative to the first adjustment component 31. For another example, the second positioning portion 5 can be located on the second adjusting component 32, and the first adjusting component 31 and the second adjusting component 32 can limit the freedom of the second adjusting component 32 in the front-back direction and the left-right direction relative to the first adjusting component 31 through the cooperation of the first positioning portion 4 and the second positioning portion 5, thereby ensuring that when the first adjusting portion 33 is adjusted alone, the second adjusting component 32 can only be translated and lifted in the up-down direction relative to the first adjusting component 31. In this embodiment, the second adjusting component 32 is connected to the first main body 1, so that the first main body 1 can only be translated and lifted in the up-down direction relative to the first adjusting component 31.

[0078] Furthermore, in some embodiments, in order to make the first positioning portion 4 and the second positioning portion 5 cooperate to limit the freedom of the first main body 1 or the second adjustment component 32 relative to the first adjustment component 31 in the front-to-back direction and the left-to-right direction, the side surfaces of the first positioning portion 4 in the front-to-back direction and the left-to-right direction and the side surfaces of the second positioning portion 5 in the front-to-back direction and the left-to-right direction correspond one to one, for example, by abutting or fitting to limit the freedom of the first main body 1 or the second adjustment component 32 relative to the first adjustment component 31 in the front-to-back direction and the left-to-right direction, so that when the first adjustment portion 33 is driven alone, the first main body 1 can only be translated and lifted along the up and down direction relative to the first adjustment component 31.

[0079] Furthermore, in some embodiments, as shown in Figures 15 to 16, the first positioning portion 4 includes a first adjusting portion 33 and a first abutting portion 42, and the second positioning portion 5 includes a stabilizing portion 51 and a second abutting portion 52. The first adjusting portion 33 is cylindrical and is rotatably disposed on the stabilizing portion 51. For example, the first adjusting portion 33 is rotatably disposed on the stabilizing portion 51 by riveting, concave-convex fitting, or screw fitting, so that the first adjusting portion 33 becomes a part of the first main body 1 or the second adjusting component 32, and the first adjusting portion 33 rotates relative to the first main body 1 or the second adjusting component 32; the first adjusting portion 33 is rotatable along the side and front-back directions and the left-right directions. The side surfaces of the stabilizing portion 51 along the front-to-back direction and the left-to-right direction correspond to each other one by one, for example, by abutting or fitting to limit the freedom of the first main body 1 or the second adjustment component 32 relative to the first adjustment component 31 along the front-to-back direction and the left-to-right direction; the first abutting portion 42 and the second abutting portion 52 abut against each other to limit the first adjustment portion 33 from driving other components of the first adjustment component 31 to rotate relative to the first main body 1, or the second adjustment component 32 to rotate relative to the first adjustment component 31 when the first adjustment portion 33 is rotating, to ensure that only the first adjustment portion 33 is rotating, so that the first main body 1 can only be translated and lifted along the up and down directions relative to the first adjustment component 31.

[0080] In some embodiments, as shown in Figures 35 to 38, the first adjustment component 31 includes a first left side panel 311 and / or a first right side panel 312, the first body 1 or the second adjustment component 32 includes a second left side panel 61 and / or a second right side panel 62; the first left side panel 311 and / or the first right side panel 312 are provided with at least one first folding portion (not shown in the figure), and the first positioning portion 4 includes a first folding portion; one end of the first folding portion is connected to the first left side panel 311, one of the left and right side surfaces of the first left side panel 311 is in close contact with one of the left and right side surfaces of the second left side panel 61, and the first folding portion passes over the second left side panel 61 and is in close contact with The other side surface of the second left side panel 61 abuts against each other, and the second left side panel 61 and the first folding portion cooperate with each other to limit the second left side panel 61 from moving in at least one of the left and right directions and the front and back directions; and / or, one end of the first folding portion is connected to the first right side panel 312, one of the left and right side surfaces of the first right side panel 312 is tightly attached to one of the left and right side surfaces of the second right side panel 62, the first folding portion passes over the second right side panel 62 and abuts against the other side surface of the second right side panel 62, and the second right side panel 62 and the first folding portion cooperate with each other to limit the second right side panel 62 from moving in at least one of the left and right directions and the front and back directions. Among them, the position of the first left side panel 311 corresponds to the position of the second left side panel 61, and the position of the first right side panel 312 corresponds to the position of the second right side panel 62. For example, when the first adjustment component 31 includes the first left side panel 311, the second adjustment component 32 includes the second left side panel 61. The first left side panel 311 and the second left side panel 61 abut against each other, and the second left side panel 61 and the first folding portion cooperate with each other to limit the movement of the second left side panel 61 in at least one of the left and right directions and the front and back directions, thereby limiting the freedom of the first main body 1 or the second adjustment component 32 relative to the first adjustment component 31 in the front and back directions and / or left and right directions, so that the first main body 1 can only be translated and lifted along the up and down directions relative to the first adjustment component 31.

[0081] The first folding portion can be, for example, a cylindrical structure, and one end of the first folding portion is inserted into the first left panel 311 or the first right panel 312. The first folding portion can be, for example, a protrusion or a convex point or a convex block structure, and one end of the first folding portion can form an integrated structure with the first left panel 311 or the first right panel 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 respectively limit the movement of the first adjustment component 31 relative to the first main body 1 or the second adjustment component 32 in the front-to-back direction. For example, there are two first folding portions respectively located at the two ends of the first left panel 311 or the first right panel 312 in the front-to-back direction, and the two first folding portions respectively cooperate with the second left panel 61 or the second right panel 62 to abut or fit with each other, thereby limiting the movement of the first adjustment component 31 relative to the first main body 1 or the second adjustment component 32 in the front-to-back direction.

[0082] In some other embodiments, as shown in Figures 35 to 38, the first adjustment component 31 includes a first left side panel 311 and / or a first right side panel 312, the first body 1 or the second adjustment component 32 includes a second left side panel 61 and / or a second right side panel 62; the second left side panel 61 and / or the second right side panel 62 is provided with at least one second folding portion 7, the second positioning portion 5 includes a second folding portion 7; one end of the second folding portion 7 is connected to the second left side panel 61, one of the left and right side surfaces of the second left side panel 61 is in close contact with one of the left and right side surfaces of the first left side panel 311, and the second folding portion 7 passes over the first left side panel 311 and is in close contact with the first left side panel 3 11, the first left side panel 311 and the second folding portion 7 cooperate with each other to limit the movement of the first left side panel 311 in at least one of the left and right directions and the front and back directions; and / or, one end of the second folding portion 7 is connected to the second right side panel 62, one of the left and right side surfaces of the second right side panel 62 is tightly attached to one of the left and right side surfaces of the first right side panel 312, the second folding portion 7 passes over the first right side panel 312 and abuts against the other side surface of the first right side panel 312, the first right side panel 312 and the second folding portion 7 cooperate with each other to limit the movement of the first right side panel 312 in at least one of the left and right directions and the front and back directions. The structure and principle of the second folding portion 7 are the same as those of the first folding portion described above, and are omitted here.

[0083] The number of second folding portions 7 can be one or more, for example, there can be at least two second folding portions 7, and the at least two second folding portions 7 can each limit the front-to-back movement of the first adjustment portion 33 and the first adjustment assembly 31 relative to the first body 1 or the second adjustment assembly 32 and the second adjustment portion 34. For example, there can be two second folding portions 7 located at either end of the second left panel 61 or the second right panel 62 in the front-to-back direction, and the two second folding portions 7 can cooperate with or abut against the first left panel 311 or the first right panel 312, respectively, to limit the front-to-back movement of the first adjustment assembly 31 relative to the first body 1 or the second adjustment assembly 32.

[0084] In some embodiments, as shown in Figures 4 to 19, 30 to 36, and 39 to 40, the second adjustment assembly 32 is connected to the first adjustment assembly 31, and the first adjustment assembly 31 is connected to the first body 1. This embodiment does not limit the positional relationship between the first body 1, the first adjustment assembly 31, and the second adjustment assembly 32. As long as the first adjustment portion 33 is adjusted individually, the first body 1 can be translated and raised only in the vertical direction relative to the first adjustment assembly 31. For example, the first body 1, the first adjustment assembly 31, and the second adjustment assembly 32 can be connected sequentially from top to bottom, or the first body 1 and the first adjustment assembly 31 can be connected from top to bottom, with the first adjustment assembly 31 located inside the second adjustment assembly 32, or the second adjustment assembly 32, the first adjustment assembly 31, and the first body 1 can be connected sequentially. By adjusting the first adjustment portion 33 individually, the first body 1 can be translated and raised only in the vertical direction relative to the first adjustment assembly 31.

[0085] Furthermore, in some embodiments, as shown in Figures 4 to 12, the second adjustment component 32 also includes a connecting part 325. The connecting part 325 can be composed of one component or at least two components connected to each other in a detachable or non-detachable manner. There is no limitation here. At least a portion of the connecting part 325 is fixedly connected to the first component 100, for example, the connecting part 325 is fastened to the first component 100 by bolts or screws; the first adjustment component 31 includes a fourth main body 314; the second adjustment part 34 connects the connecting part 325 and the fourth main body 314. When the second adjustment part 34 is adjusted alone, the fourth main body 314 can move in the front and rear directions relative to the connecting part 325. Part of the second adjusting portion 34 may be, for example, an eccentric member or a sheet-like body in the shape of a Loehler triangle, and another part of the second adjusting portion 34 may be rotatably disposed on the connecting member 325. The fourth main body 314 may be formed with a mating portion. During the rotation of the second adjusting portion 34 relative to the connecting member 325, the fourth main body 314 may be driven to slide relative to the connecting member 325 in the front-to-back direction, thereby causing the fourth main body 314 to move relative to the connecting member 325 in the front-to-back direction. For example, the second adjusting portion 34 may be a fastener with an external thread, and the fourth main body 314 may be formed with a slide groove extending in the front-to-back direction. The second adjusting portion 34 may pass through the slide groove and then be threadedly connected to the connecting member 325. When the second adjusting portion 34 and the fourth main body 314 are relatively loosened, the fourth main body 314 and the connecting member 325 may be able to move in the front-to-back direction.

[0086] In some embodiments, the first adjustment portion 33 connects the fourth body 314 and the first body 1. When the first adjustment portion 33 is adjusted alone, the first body 1 can be translated and raised only in the up and down directions relative to the fourth body 314, so that the first body 1 can be translated and raised only in the up and down directions relative to the connecting part 325, thereby allowing the first body 1 to be translated and raised only in the up and down directions relative to at least a part of the base device 3.

[0087] Specifically, in some embodiments, the first adjustment portion 33 is a cylindrical structure and at least a portion of its outer or inner wall is a threaded structure. One end of the first adjustment portion 33 is threadedly connected to the first body 1, and the other end of the first adjustment portion 33 is connected to the fourth body 314. Alternatively, one end of the first adjustment portion 33 is threadedly connected to the fourth body 314, and the other end of the first adjustment portion 33 is connected to the first body 1. When the first adjustment portion 33 is driven to rotate relative to the fourth body 314, the first body 1 can be translated and raised only in the vertical direction relative to the fourth body 314, thereby allowing the first body 1 to be translated and raised only in the vertical direction relative to the connecting member 325. The first adjustment portion 33, for example, is engaged with the side surfaces in the front-to-back direction and the left-to-right direction through the above-mentioned stabilizing portion 51 to limit the freedom of the first body 1 or the second adjustment assembly 32 in the front-to-back direction and the left-to-right direction relative to the first adjustment assembly 31.

[0088] In some embodiments, the first body 1 includes a connecting plate 11, a left side plate 12, and a right side plate 13, wherein the connecting plate 11, the left side plate 12, and the right side plate 13 enclose 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 portion of the fourth body 314 is disposed in the mounting groove 14 or at least a portion of the fourth body 314 is disposed below the first body 1, at least a portion of the connecting component 325 is disposed in the mounting groove 14 or at least a portion is disposed below the fourth body 314, and at least one of the left side and the right side of the fourth body 314 is in close contact with an outer side surface or an inner side surface of the mounting groove 14, so that during the process of adjusting the first adjustment part 33 alone, the left side or the right side of the fourth body 314 is mutually limited with the outer side surface or the inner side surface of the mounting groove 14 to prevent the first body 1 from moving in the left and right directions relative to the fourth body 314 or the connecting component 325, thereby allowing the first body 1 to only achieve translational movement and lifting along the up and down directions relative to the connecting component 325.

[0089] In some embodiments, the first main body 1 includes a connecting plate 11, a left side plate 12 and a right side plate 13, and the connecting plate 11, the left side plate 12 and the right side plate 13 are surrounded to form a mounting groove 14; at least a portion of the connecting part 325 can be located in the mounting groove 14 or at least a portion 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 an outer side or an inner side of the mounting groove 14, so that in the process of adjusting the first adjustment 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 and right directions relative to the connecting part 325, so that the first main body 1 can only be translated and lifted along the up and down directions relative to the connecting part 325.

[0090] In some embodiments, as shown in Figures 20 to 32, the first adjustment component 31 and the second adjustment component 32 are connected, and the second adjustment component 32 is connected to the first body 1. This embodiment does not limit the positional relationship between the first body 1, the first adjustment component 31, and the second adjustment component 32. The first body 1 is connected to the first adjustment component 31 via the second adjustment component 32. When the first adjustment portion 33 is adjusted alone, the first body 1 can only move horizontally and vertically relative to the first adjustment component 31.

[0091] Furthermore, in some embodiments, as shown in Figures 22 to 23, the second adjustment component 32 also includes a fifth body 324, and the first adjustment component 31 also includes a fourth body 314, which can be at least a part of the fourth body 314 used to be fixedly connected to the first component 100, for example, the fourth body 314 is fastened to the first component 100 by bolts or screws; the fifth body 324 can be translated and lifted relative to the fourth body 314 in the up and down directions, so that the first body 1 can be translated and lifted relative to the fourth body 314 in the up and down directions, so that the first body 1 can be translated and lifted only in the up and down directions relative to at least a part of the base device 3.

[0092] In some embodiments, when the second adjustment portion 34 is adjusted alone, the first body 1 can only move in the front-to-back direction relative to the fifth body 324 , and thus the first body 1 can only move in the front-to-back direction relative to the fourth body 314 .

[0093] Specifically, in some embodiments, the first adjustment portion 33 is a cylindrical structure with at least a portion of its outer or inner wall being threaded. One end of the first adjustment portion 33 is threadedly connected to the fifth body 324, and the other end of the first adjustment portion 33 is connected to the fourth body 314. Alternatively, one end of the first adjustment portion 33 is threadedly connected to the fourth body 314, and the other end of the first adjustment portion 33 is connected to the fifth body 324. When the first adjustment portion 33 is driven to rotate relative to the fourth body 314, the fifth body 324 can be translated and raised relative to the fourth body 314 in the vertical direction, thereby enabling the first body 1 to be translated and raised relative to the fourth body 314 in the vertical direction, thereby enabling the first body 1 to be translated and raised relative to at least a portion of the base device 3 only in the vertical direction. The first adjustment portion 33, for example, is engaged with the side surfaces of the aforementioned stabilizing portion 51 in the front-to-back and left-to-right directions to limit the freedom of the first body 1 or the second adjustment assembly 32 in the front-to-back and left-to-right directions relative to the first adjustment assembly 31.

[0094] In some embodiments, as shown in Figures 11 to 12, 20 to 21, 23 to 25, and 32, a disassembly device 10 is used to connect or disconnect the interior of the first body 1, and / or the interior of the first adjustment assembly 31, and / or the interior of the second adjustment assembly 32, and / or between the first body 1 and the second adjustment assembly 32, and / or between the first adjustment assembly 31 and the second adjustment assembly 32, and / or between the first adjustment assembly 31 and the first body 1. The disassembly device 10 may be a sliding disassembly device, a pressing disassembly device, or another type of disassembly device. The specific structure of the disassembly device 10 is conventional in the art. For example, a pressing disassembly device 10 includes a button and a spring. A buckle is provided at one end of the button. Pressing the other end of the button controls the buckle to engage or disengage, thereby connecting or disconnecting the aforementioned components. The spring is used to drive the pressing member to automatically reset.

[0095] In some embodiments, as shown in FIG18 , the base assembly 3 includes a third adjustment assembly 35 . The third adjustment assembly 35 is disposed within the first body 1 , and / or within the first adjustment assembly 31 , and / or within the second adjustment assembly 32 , and / or between the first body 1 and the second adjustment assembly 32 , and / or between the first adjustment assembly 31 and the second adjustment assembly 32 , and / or between the first adjustment assembly 31 and the first body 1 . The third adjustment assembly 35 includes a third adjustment portion. When the third adjustment portion is adjusted alone, the first body 1 can move left and right relative to at least a portion of the base assembly 3 . The structure of the third adjustment portion is the same as or similar to that of the second adjustment portion 34 of this embodiment. For details, please refer to the description of the second adjustment portion 34 , and further details are omitted here. By adding the third adjustment assembly 35 and the third adjustment portion, three-dimensional adjustment of the hinge assembly of this embodiment is achieved, improving adjustment convenience and installation position accuracy.
