As shown in fig. 1 to 3, a hinge mounting structure 1 includes a first bearing portion, a second bearing portion, and a hinge mechanism 1 for rotatably connecting the first bearing portion to the second bearing portion, where the hinge mechanism 1 includes a first connecting rod 11, one end of the first connecting rod 11 is rotatably connected to the first bearing portion through a first rotating shaft 14, and the other end of the first connecting rod 11 is rotatably connected to the second bearing portion through a second rotating shaft 15, rotation of the first bearing portion drives the first rotating shaft 14 to displace, and the first connecting rod 11 limits the displacement to move on a circle with the second rotating shaft 15 as a circle center and a distance between the first rotating shaft 14 and the second rotating shaft 15 as a radius.

In the above solution, the hinge mechanism 1 is used to connect two bearing parts, so as to realize the rotation of the first bearing part relative to the second bearing part. Particularly, when the first bearing part is connected to the second bearing part in an embedded manner, the rotating shaft of the first bearing part is moved through the first connecting rod 11, so that the rotating position of the first bearing part is away from the second bearing part by a certain distance, and the first connecting rod 11 rotates around the second rotating shaft 15 on the second bearing part, so that when the first bearing part is opened or closed in a rotating manner, a sufficient space is formed between the edge of the first bearing part and the second bearing part, so that the embedded first bearing part can be opened or closed relative to the second bearing part, and the problems of collision, abnormal sound and the like are avoided.

Further, the hinge mechanism 1 further includes a limiting portion for limiting the rotational displacement of the first rotating shaft 14, one end of the limiting portion is connected to the first rotating shaft 14, and the other end is connected to the second bearing portion through a third rotating shaft 16.

In the above solution, the hinge mechanism 1 further includes a limiting portion for limiting the rotational displacement of the first rotating shaft 14, the rotational displacement of the first rotating shaft 14 is limited in a corresponding angle, usually, the opening angle between the two bearing portions is smaller than 180 degrees, for embedded connection, in order to prevent the rotation angle of the first bearing portion from being too large, or prevent the first bearing portion from rotating to the position above the second bearing portion and damaging the second bearing portion or generating collision noise, etc., the limiting portion is generally set to limit the rotation of the first bearing portion in the corresponding angle range, in this embodiment, the limiting portion is set to limit the rotational displacement of the first rotating shaft 14 in the corresponding angle. One end of the limiting part is connected with the first rotating shaft 14 to control the action of the first bearing part, and the other end is connected with the second bearing part to provide a fulcrum or power for the limiting part. The limiting part can be an elastic part with one end connected with the first bearing part and the other end connected with the second bearing part.

Furthermore, the limiting part comprises a second connecting rod 12 and a third connecting rod 13, one end of the second connecting rod 12 is rotatably connected with the first rotating shaft 14 through a fourth rotating shaft 17, the other end of the third connecting rod 13 is rotatably connected with the second bearing part through a third rotating shaft 16, the second connecting rod 12 is driven to displace by the displacement of the first rotating shaft 14, and further the fourth rotating shaft 17 is driven to displace, and the displacements of the first rotating shaft 14 and the fourth rotating shaft 17 are limited by the second connecting rod 12 and the third connecting rod 13 on one side of a connecting line between the second rotating shaft 15 and the third rotating shaft 16.

In the above-described embodiment, the fourth rotation shaft 17 is used to rotatably connect the second link 12 and the third link 13, and the fourth rotation shaft 17 is a free rotation shaft and rotates around the third rotation shaft 16. The angle by which the first axis of rotation 14 is rotatable about the second axis of rotation 15 depends on the length of the respective link and the distance between the second axis of rotation 15 and the third axis of rotation 16.

When the first bearing part is opened, when the length of the first connecting rod 11 plus the distance between the second rotating shaft 15 and the third rotating shaft 16 is equal to the length of the second connecting rod 12 plus the length of the third connecting rod 13, the fourth rotating shaft 17 is blocked by the first connecting rod 11 and the second rotating shaft 15 in the process of upward rotation, and cannot continue to rotate through the first connecting rod 11, so that the rotating angle of the first rotating shaft 14 is limited to be between-90 ° and 90 ° through the second connecting rod 12 and the third connecting rod 13, the edge values of-90 ° and 90 ° can be infinitely approached, when the rotating angle of the first rotating shaft 14 is close to 90 °, the gravity center of the first bearing part is shifted to the other side of the Y axis, so that the first bearing part cannot be closed under the action of gravity, but can be kept in an opened state when being opened to the maximum state, and is generally preferably 0 ° to 90 °; when the length of the first connecting rod 11 plus the distance between the second rotating shaft 15 and the third rotating shaft 16 is greater than the length of the second connecting rod 12 plus the length of the third connecting rod 13, the length of the second connecting rod 12 and the third connecting rod 13 limits the rotating angle to be between-90 degrees and 90 degrees, the edge value cannot be reached, the difference exists between the edge value and the rotating angle, and the small angle cannot ensure that the gravity center of the first bearing part always exceeds the Y axis; when the length of the first link 11 plus the distance between the second rotating shaft 15 and the third rotating shaft 16 is less than the length of the second link 12 plus the length of the third link 13, the third link 13 is blocked by the second rotating shaft 15 in the process of upward rotation and cannot rotate continuously, and further the rotating angle range of the first rotating shaft 14 is larger than the angle range of-90 ° to 90 ° through the second link 12 and the third link 13, but when the first rotating shaft 14 deviates beyond the Y axis, the difficulty of closing the first bearing part is increased, and a relatively large force needs to be provided for closing, so that the situation is generally not selected.

The lengths of the first link 11 and the third link 13 are equal, and the distance between the second rotating shaft 15 and the third rotating shaft 16 is equal to the length of the second link 12, that is, the length of the first link 11 plus the distance between the second rotating shaft 15 and the third rotating shaft 16 is equal to the length of the second link 12 plus the length of the third link 13, and the first bearing part can be kept in an open state when being opened to the maximum position.

Further, the hinge mechanism 1 further comprises a hinge seat 18, the hinge seat 18 is detachably and fixedly connected to the second bearing part, and the first bearing part is connected with the second bearing part through the hinge seat 18.

The base 182 is detachably connected to the second bearing part through screws 183 and positioning structures, and the number of the screws 183 and the positioning structures is at least three and is not in the same line. Preferably, in this embodiment, two screws 183 and one positioning column 184 are included, which are not in the same straight line, the positioning column 184 may be disposed on the second bearing portion or may be disposed on the base 182, and the corresponding positioning hole is disposed on the base 182 or the second bearing portion. More preferably, the screws 183 and the positioning posts 184 are not in the same straight line, because mounting misalignment or looseness may occur in the same straight line, and at least three screws 183 or positioning posts 184 are formed in total, and form a triangle in different straight lines, so that the triangle is most stable and is not in the same straight line.

In addition, when two bearing parts are hinged by a hinge at present, a damping structure is generally required to be additionally arranged, so that the first bearing part directly falls down to smash a hand or hurt a second bearing part due to the action of gravity in the closing process, and particularly, the hinge is used in household appliances. In this embodiment, the hinge mechanism 1 includes a link mechanism having at least one link, and the link mechanism includes some revolute pairs including a revolute pair of a link and a rotary shaft, a revolute pair of a link and a link, a revolute pair of a rotary shaft and a bearing portion, and the like. Including the first pivoted damping portion of bearing part of damping in this embodiment, no longer use damping structure just to reach the damping effect, reduce the abnormal sound, prevent to pound the hand or injure the second bearing part, save the cost.

The preferred embodiment is to provide a damping shim 19 in the revolute pair of the connecting rod, as shown in figure 3, to provide a damping effect without affecting the normal rotation of the first bearing part.
