Embodiment one

As shown in Figures 1-3, a hinge mounting structure 1 includes a first bearing part, a second bearing part, and a hinge mechanism 1 that rotatably connects the first bearing part to the second bearing part. 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 part through the first rotating shaft 14, and the other end is rotatably connected to the second bearing part through the second rotating shaft 15. On the bearing part, the rotation of the first bearing part drives the displacement of the first rotating shaft 14, and the first connecting rod 11 limits the displacement between the first rotating shaft 14 and the second rotating shaft 15 with the second rotating shaft 15 as the center of the circle. The distance between them moves on a circle with a radius.

In the above solution, the hinge mechanism 1 is used to connect two bearing parts to realize the rotation of the first bearing part relative to the second bearing part. Especially when the first load-bearing part is embedded and connected to the second load-bearing part, the rotation axis of the first load-bearing part is moved by the first connecting rod 11, so that the rotation position of the first load-bearing part is a section away from the second load-bearing part. distance, and rotate around the second rotating shaft 15 on the second bearing part through the first connecting rod 11, so that when the first bearing part rotates to open or close, there is enough space between its edge and the second bearing part, so that the embedded The first bearing part of the formula can be opened or closed relative to the second bearing part, and there will be no problems such as collision and abnormal noise.

Further, the hinge mechanism 1 also includes a limiting part that limits the rotational displacement of the first rotating shaft 14, one end of the limiting part is connected to the first rotating shaft 14, and the other end is connected to the second bearing part through the third rotating shaft 16. connect.

In the above solution, the hinge mechanism 1 further includes a limiting part that limits the rotational displacement of the first rotating shaft 14, and limits the rotational displacement of the first rotating shaft 14 within a corresponding angle. Usually, the opening angle between the two bearing parts is less than 180 degrees, for the embedded connection, in order to prevent the rotation angle of the first bearing part from being too large, or to prevent the second bearing part from being damaged when the first bearing part rotates to accidentally contact with the upper part of the second bearing part or produce a collision noise etc. Generally, a limiting part is provided to limit the rotation of the first bearing part within a corresponding angle range. In this embodiment, a limiting part is provided to limit the rotational displacement of the first rotating shaft 14 within a corresponding angle. One end of the limiting part is connected to the first rotating shaft 14 to control the movement of the first bearing part, and the other end is connected to the second bearing part to provide a fulcrum or power for the limiting part. The limiting part may be an elastic part whose one end is connected to the first bearing part and the other end is connected to the second bearing part.

Further, the limiting part includes a second connecting rod 12 and a third connecting rod 13 rotatably connected at one end through the fourth rotating shaft 17, and the other end of the second connecting rod 12 is rotatably connected with the first rotating shaft 14 , the other end of the third connecting rod 13 is rotatably connected to the second bearing part through the third rotating shaft 16, the displacement of the first rotating shaft 14 drives the displacement of the second connecting rod 12, and then drives the displacement of the fourth rotating shaft 17 , the displacement of the first rotating shaft 14 and the fourth rotating shaft 17 is limited by the second connecting rod 12 and the third connecting rod 13 to one side of the line connecting the second rotating shaft 15 and the third rotating shaft 16 .

In the above solution, the fourth rotating shaft 17 is used to rotatably connect the second connecting rod 12 and the third connecting rod 13 , and the fourth rotating shaft 17 is a free rotating shaft that rotates around the third rotating shaft 16 . The rotatable angle of the first rotating shaft 14 around the second rotating shaft 15 depends on the length of each connecting rod and the distance between the second rotating shaft 15 and the third rotating shaft 16 . As shown in Figure 1, assuming that the line connecting the second rotation axis 15 and the third rotation axis 16 is the Y axis, and the second rotation axis 15 is the origin, then the straight line passing through the origin and perpendicular to the Y axis on the surface shown in the figure is the X axis . When the first bearing part is opened, 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 length, the fourth rotating shaft 17 is blocked by the first connecting rod 11 and the second rotating shaft 15 during the upward rotation, and cannot continue to rotate through the first connecting rod 11, and then passes through the second connecting rod 12 and the third connecting rod. The rod 13 limits the rotation angle of the first rotation axis 14 between -90° and 90°, which can be infinitely close to the edge values of -90° and 90°. When the rotation angle of the first rotation axis 14 is close to 90°, the first The center of gravity of the bearing part is shifted to the other side of the Y axis, so that the first bearing part will not be closed under the action of gravity, but can be kept open when it is opened to the maximum state, generally preferably 0° to 90°; when 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 second connecting rod 12 and The length of the third connecting rod 13 limits the rotation angle to -90° to 90°, which cannot reach the edge value, and there is a gap with the edge value, and the angle is too small to ensure that the center of gravity of the first bearing part must exceed the Y axis , at this time, the first bearing part will not be able to maintain the open state under the action of gravity, and will automatically close, so this situation is generally not selected; when the length of the first connecting rod 11 plus the second rotation axis 15 and the third rotation axis When the distance between 16 is less than the length of the second connecting rod 12 plus the length of the third connecting rod 13, the third connecting rod 13 is stuck by the second rotating shaft 15 during the upward rotation and cannot continue to rotate. Furthermore, through the second connecting rod 12 and the third connecting rod 13, the rotating angle range of the first rotating shaft 14 is greater than the angle range of -90° to 90°, but because when the first rotating shaft 14 deviates beyond the Y axis, the The difficulty of the first load-bearing part increases, and relatively large force needs to be provided for closing, so this situation is generally not selected. When the first bearing part is closed, the closing position with the second bearing part is to limit the position of the first bearing part.

Further, each connecting rod is riveted with the rotating shaft, the length of the first connecting rod 11 and the third connecting rod 13 are equal, the distance between the second rotating shaft 15 and the third rotating shaft 16 and the distance between the second connecting rod 12 equal in length.

In addition, at present, when hinges are used to connect the two bearing parts, it is generally necessary to install an additional damping structure, so that the first bearing part will fall directly due to the action of gravity and hit the second bearing part or damage the second bearing part during the closing process, especially for household appliances. The case where hinges are used. In this embodiment, the hinge mechanism 1 includes a link mechanism with at least one link, and the link mechanism includes some rotating pairs, including the rotating pairs of the connecting rod and the rotating shaft, and the rotation of the connecting rod and the connecting rod. A pair, a rotating shaft and a rotating pair of the bearing part, etc. In this embodiment, a damping part for damping the rotation of the first bearing part is included, and the damping effect is achieved without using a damping structure, which reduces abnormal noise, prevents the second bearing part from being hit or scratched, and saves costs.
