In the utility model, the words for expressing the position and the direction are described, wherein the side where the door body is located is taken as the front side when the refrigerator is normally used, and the direction of the pivoting side far away from the refrigerator is taken as the outer side, for example, in the side-by-side combination refrigerator, the direction of the self-pivoting side far away from the other door body in the opening process of one door body is moved outwards, and the direction of the self-pivoting side close to the other door body in the lifting and opening process of one door is moved inwards. The terms first, second, third and the like in the present invention are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated; in addition, unless expressly stated or limited otherwise, the term "coupled" is intended to be inclusive, i.e., that a connection may be direct or indirect via intermediate media, fixed or movable, or detachable or integral. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
Referring to fig. 1, the present invention provides a hinge 10, wherein the hinge 10 is used to connect a door 20 to a refrigerator body 30, and in the present embodiment, the hinge 10 is applied to an embedded refrigerator 100, and the door 20 of the refrigerator 100 is specifically described as an example of a door opening by rotating left and right.
It should be emphasized that the hinge 10 of the present embodiment is not only applicable to the refrigerator 100, but also applicable to other scenes, such as other household appliances, for example, a cabinet, a wine cabinet, a wardrobe, a microwave oven, and the like.
Referring to fig. 2-3, the hinge 10 includes a fixed seat 1 for being mounted on a box 30, a movable seat 2 mounted on a door 20, and a linkage assembly 3 hinged between the fixed seat 1 and the movable seat 2, one of the movable seat 2 and the fixed seat 1 is provided with a guide slot 4, and in a process that the movable seat 2 rotates relative to the fixed seat 1, the linkage assembly 3 is matched with the guide slot 4, that is, one end of the linkage assembly 3 moves along the guide slot 4, so that the movable seat 2 moves relative to the fixed seat 1 according to a preset track, that is, the door 20 moves according to the preset track.
When the door body 20 is in a closed state, the linkage assembly 3 is in a folded state, and at the moment, the movable seat 2 is close to the fixed seat 1. When the door 20 is opened, that is, when the door 20 moves away from the cabinet 30, the linkage assembly 3 gradually extends from the folded state to the unfolded state. In the process of closing the door 20, that is, when the door 20 moves toward the box 30, the linkage assembly 3 gradually contracts from the unfolded state to the folded state, and then the door 20 is in the closed state.
It can be understood that, when the door 20 rotates in a direction away from the box 30, the movable seat 2 rotates in a direction away from the fixed seat 1 relative to the fixed seat 1.
Further, the preset trajectory refers to that, in the process that the movable seat 2 rotates relative to the fixed seat 1, the movable seat 2 moves along a first direction and a second direction which are intersected with each other simultaneously under the guidance of the guide groove 4, and a displacement ratio between the displacement of the movable seat 2 in the first direction and the displacement of the movable seat 2 in the second direction changes along with the rotation angle of the movable seat 2. According to specific requirements, the displacement of the door body 20 in the first direction and the second direction in the opening process can be adjusted, and the motion track of the door body 20 is controlled.
Specifically, the first direction is a forward direction of the fixed seat 1 toward the movable seat 2, the second direction is a lateral direction of the pivot side of the hinge 10, and the first direction is perpendicular to the second direction, that is, the first direction is a forward direction of the refrigerator 100, and the second direction is an outward direction of the refrigerator 100 on the pivot side. On one hand, in the opening process of the door body 20, the pivoting end of the door body 20 is gradually moved to the front side of the wall/cabinet located at the pivoting side, so that interference between the door body 20 and the wall/cabinet located at the pivoting side in the opening process can be avoided, and the door body 20 can adapt to various application scenes, such as the application scenes of the embedded refrigerator 100; on the other hand, in the process of opening the door body 20, the pivoting end of the door body 20 is moved outward, so that the opening angle of the door body 20 can be increased, and a user can conveniently check and take the articles in the box body 30.
Further, in an embodiment, during the process of rotating and opening the movable seat 2 relative to the fixed seat 1, the movable seat 2 is configured to gradually increase a displacement ratio between a displacement in the first direction and a displacement in the second direction. Therefore, in the first stage of opening the door, the main movement of the door 20 is outward movement, and at this time, the rotation angle and the forward movement distance of the door 20 are both small, so that in the side-by-side combination refrigerator 100, the door 20 can be prevented from interfering with another door 20 in the process of opening the door. In the second stage of opening the door, the main movement of the door 20 is forward movement, and at this time, the rotation angle and the outward movement distance of the door 20 are small, so that the door 20 can be prevented from interfering with the wall/cabinet and the like on the pivoting side. In the third stage of opening the door, the main movement of the door 20 is rotation, and at this time, the forward movement and outward movement distances of the door 20 are both small, so as to further increase the opening angle of the door 20, and thus, a user can conveniently check and take the articles in the box body 30.
In another embodiment, during the process of opening the movable seat 2 by rotating relative to the fixed seat 1, the movable seat 2 is configured to gradually decrease the displacement ratio between the displacement in the first direction and the displacement in the second direction. Therefore, in the first stage of opening the door, the main movement of the door 20 is forward movement, and at this time, the rotation angle and the outward movement distance of the door 20 are both small, it can be understood that, after the door 20 moves forward by a certain distance, when the door 20 continues to rotate in the direction away from the cabinet 30, the possibility of interference with the wall/cabinet and the like on the pivoting side is small, and therefore, the door 20 can be prevented from interfering with the wall/cabinet and the like on the pivoting side. In the second stage of opening the door, the main movement of the door 20 is outward movement, and at this time, the forward movement distance of the door 20 is small, so that the requirement on the front space of the refrigerator 100 in the door opening process is reduced. In the third stage of opening the door, the main movement of the door 20 is rotation, and at this time, the forward movement and outward movement distances of the door 20 are both small, so as to further increase the opening angle of the door 20, and thus, a user can conveniently check and take the articles in the box body 30.
Further, at least one section of the guide groove 4 is a curved groove, it is known that the curvature of each point of the curved groove is different, and the relationship among the rotation angle, the forward movement distance and the outward movement distance of the door body 20 in the opening process of the door body 20 can be adjusted by changing the curvature size, the curvature variation trend, the shape and the like of the curved groove. That is, the movable seat 2 can drive the displacement ratio between the displacement of the door body 20 in the first direction and the displacement in the second direction to change along with the rotation angle of the movable seat 2, so as to avoid the door body 20 from interfering with the wall/cabinet and the like on the pivoting side in the opening process, and increase the opening angle of the door body 20, so that the user can conveniently look up and take the articles in the box 30.
Referring to fig. 2-3, in a first embodiment of the present invention, the guiding slot 4 is disposed on the movable base 2; a section of the guide groove 4 away from the pivot side of the hinge 10 is a convex curved groove 41, and the convex curved groove 41 extends from an end away from the pivot side toward the pivot side and toward the fixed base 1, that is, the curvature of the convex curved groove 41 gradually decreases in a direction gradually approaching the pivot side.
When the door body 20 is in a closed state, one end of the linkage assembly 3, which is matched with the guide groove 4, is located at one end of the convex curve groove 41, which is far away from the pivoting side, and in the process of opening the door, one end of the linkage assembly 3, which is matched with the guide groove 4, moves along the convex curve groove 41 to control the initial motion trajectory of the door body 20, so that interference between the door body 20 and a wall/cabinet and the like located on the pivoting side in the opening process is avoided.
Specifically, in the present embodiment, the curvature of the convex curved groove 41 gradually decreases in a direction gradually approaching the pivot side, and the displacement ratio between the displacement of the movable seat 2 in the first direction and the displacement in the second direction gradually decreases as the rotation angle of the movable seat 2 increases, in the process that the end of the linkage assembly 3 that is engaged with the guide groove 4 moves from the end of the convex curved groove 41 away from the pivot side toward the pivot side. Therefore, in the first stage of opening the door, the curvature of the convex curved groove 41 is large, the main movement of the door 20 is forward movement, and at this time, the rotation angle and the outward movement distance of the door 20 are both small, and it can be understood that, when the door 20 continues to rotate in the direction away from the cabinet 30 after the door 20 moves forward by a certain distance, the possibility of interference with the wall/cabinet and the like on the pivoting side is small, and therefore, the door 20 can be prevented from interfering with the wall/cabinet and the like on the pivoting side. In the second stage of opening the door, the curvature of the convex curved groove 41 is smaller, the main movement of the door body 20 is outward movement, and at this time, the forward movement distance of the door body 20 is smaller, so that the requirement on the front side space of the refrigerator 100 in the door opening process is reduced.
Further, a section of the guide groove 4 close to the pivoting side of the hinge 10 is a linear groove 42, the convex curve groove 41 is communicated with the linear groove 42, in a third stage of door opening, one end of the linkage assembly 3, which is matched with the guide groove 4, moves towards the pivoting side along the linear groove 42, at this time, the main movement of the door body 20 is rotation, at this time, the forward movement and the outward movement of the door body 20 are both small, the opening angle of the door body 20 can be increased, and a user can conveniently view and take articles in the box body 30.
In the present embodiment, the guide groove 4 is L-shaped. Of course, this is not a limitation.
Further, the linkage assembly 3 includes a first rocking bar 31, a second rocking bar 32, and a third rocking bar 33. The rotating end of the first rocker 31 is rotatably connected to the fixed seat 1, and the swinging end of the first rocker 31 is slidably connected to the guide groove 4. The rotating end of the second rocker 32 is rotatably connected to the fixed seat 1. The rotating end of the third rocker 33 is rotatably connected to the movable seat 2, the swinging end of the third rocker 33 is rotatably connected to the swinging end of the second rocker 32, and the third rocker 33 is crossed with the first rocker 31 and is rotatably connected at the crossed position. Namely, the linkage assembly 3, the fixed seat 1 and the movable seat 2 together form a five-bar linkage structure.
The arm of force formed by the linkage assembly 3 is relatively long, so that the door 20 can move forward to a position far away from the front end of the refrigerator body 30 during the door opening process, and therefore, after the hinge 10 is applied to the embedded refrigerator 100, the door 20 of the embedded refrigerator 100 can easily move to the front end of the wall/cabinet on the pivoting side during the door opening process, thereby effectively preventing the door 20 from interfering with the wall/cabinet on the pivoting side.
Specifically, the rotation end of the second rocker 32 is located on the side of the rotation end of the first rocker 31 far away from the movable seat 2, so that the linkage assembly 3 can be switched between the folded state and the unfolded state, that is, the linkage assembly 3 can control the door body 20 to be switched between the closed state and the open state and control the moving track of the door body 20.
Further, the movable seat 2 has an accommodating cavity 5 opened toward the fixed seat 1, and the accommodating cavity 5 is used for accommodating the linkage assembly 3 in a folded state, so as to enhance the appearance effect of the refrigerator 100.

Specifically, the curvature of the convex curved groove gradually increases in a direction gradually approaching the pivot side, and a displacement ratio between a displacement of the movable seat 2 in the first direction and a displacement of the movable seat 2 in the second direction gradually increases as a rotation angle of the movable seat 2 increases in a process in which an end of the linkage assembly 3, which is engaged with the guide groove 4a, moves from an end of the convex curved groove away from the pivot side toward the pivot side. Therefore, in the first stage of opening the door, the curvature of the convex curve groove is small, the main movement of the door body 20 is outward movement, at this time, the rotation angle and the forward movement distance of the door body 20 are small, and in the side-by-side combination refrigerator 100, the door body 20 can be prevented from interfering with another door body 20 in the door opening process. In the second stage of opening the door, the curvature of the convex curved groove is large, the main motion of the door body 20 is forward movement, and at this time, the rotation angle and the outward movement distance of the door body 20 are small, so that the door body 20 can be prevented from interfering with a wall/cabinet and the like on the pivoting side. In the third stage of opening the door, the main movement of the door 20 is rotation, and at this time, the forward movement and outward movement distances of the door 20 are both small, so as to further increase the opening angle of the door 20, and thus, a user can conveniently check and take the articles in the box body 30.
