The hinge 100 of this embodiment includes a box connection seat 60 and a door connection seat 70, where the box connection seat 60 includes a box connection plate and a rotating shaft 80, the door connection seat 70 is rotatably connected to the rotating shaft 80, the door connection seat 70 is fixedly connected to the door, and the box connection seat 60 is fixedly connected to the box.

The door body of this embodiment is turned over from the side of the case, and the hinge 100 is correspondingly disposed on the side of the case and the door body. In order to clearly illustrate the connection positional relationship, in the present embodiment, the direction of the hinge 100 toward the case is defined as front, the opposite direction is defined as rear, the direction of the door with respect to the case is defined as up, the opposite direction is defined as down, and both sides of the hinge 100 are defined as left and right from the front, respectively. Therefore, when the door is closed, the case connecting seat 60 is located directly under the door connecting seat 70.

Referring to fig. 3 and 4, the hinge 100 further includes a supporting portion, where the supporting portion includes a supporting beam 20, a supporting rod 30, an elastic member 50 and a spacer 40, the supporting beam 20 is fixedly connected with a box connecting member, the supporting rod 30 is used for supporting a door body connecting seat 70, the elastic member 50 is sleeved outside the supporting rod 30, the elastic member 50 is set between the supporting rod 30 and the supporting beam 20 in a compressed state, the supporting rod 30 includes a plurality of supporting edges 31, the spacer 40 is supported between the supporting edges 31 and an end surface of the elastic member 50, and the supporting edges 31 extend on a periphery of the spacer 40.

The fact that the holding edge 31 extends over the periphery of the spacer 40 means that the holding edge 31 is not in point-like contact with the spacer 40, but, as shown in fig. 3 to 6, has a certain length over the periphery of the spacer 40, and this length may be the whole periphery of the spacer 40, or may be a part of the whole periphery, for example, the whole holding edge 31 in fig. 6 is held against approximately a quarter of the whole periphery, and the holding edge 31 has a certain thickness, so that the contact between the holding edge 31 and the spacer 40 is a large-area surface contact.

The elastic member 50 may be provided as a spring, and the spring in a compressed state may provide a driving force for opening the door body, and the support beam 20 provides support and limitation to the up-and-down movement of the support rod 30.

In addition, in this embodiment, the hinge 100 further includes a swinging shaft fixedly connected to the door body connecting seat 70, a sliding shaft slidingly connected to the box body connecting seat 60, and a connecting piece and a limiting portion both rotationally connected to the swinging shaft and the sliding shaft, wherein the door body connecting seat 70 rotates around the rotating shaft 80 of the box body connecting seat 60, and at the same time, the swinging shaft fixed on the door body connecting seat 70 swings together, the swinging shaft pulls the connecting piece to drive the sliding shaft to move together, the swinging shaft is parallel to the rotating shaft 80, the sliding shaft is parallel to the swinging shaft, i.e. three shafts are parallel to each other, and the limiting portion limits the sliding shaft to move along a straight line; when the door body connecting seat 70 rotates around the rotating shaft 80 in a turnover manner, the sliding shaft is driven to move and is always parallel to the rotating shaft 80 under the limitation of each component.

The hinge 100 further includes a limiting portion for limiting the movement direction of the sliding shaft to be parallel to the box connecting plate, the limiting portion may be disposed on the box connecting seat 60, or may be disposed on the package cover plate of the hinge 100, or may be disposed in multiple places at the same time, so as to limit the movement mode of the sliding shaft, so that the sliding shaft can only perform linear movement under the traction of the connecting piece, and the rotating shaft 80, the door connecting seat 70, the swinging shaft, the connecting piece, the sliding shaft and the limiting portion together form a crank slider mechanism for converting the swinging movement of the door connecting seat 70 into the linear movement of the sliding shaft. In this embodiment, the limiting portions are linear grooves provided on a pair of side walls of the case connecting seat 60, as shown in fig. 3 and 4.

Thus, the supporting rod 30 of the present embodiment only moves vertically on a straight line, the supporting relationship between the supporting rod 30 and the spacer 40 is that the supporting is in a pure vertical direction, ideally, the end surface of the spring is a circular ring 42 surface, so that the spacer 40 is in a horizontal state and is perpendicular to the moving direction of the supporting rod 30. As described in the background art, the end surface of the spring is not necessarily an ideal ground plane, and if the support rod 30 swings, the support rod 30 does not facilitate the horizontal movement of the spacer 40, so that the support rod 30 moves only in the up-down direction, which is beneficial to keeping the spacer 40 horizontal and the spring vertical.

Further, as shown in fig. 3 to 6, the support bar 30 includes two abutment edges 31, and the two abutment edges 31 extend in opposite directions on the peripheral edge of the spacer 40, respectively. The two abutting edges 31 are beneficial to increasing the contact area of the supporting rod 30 and the gasket 40, so that the pressure intensity is smaller, the force of the supporting rod 30 extruding the gasket 40 is more dispersed, and the deformation of the gasket 40 is avoided.

Further, the two holding edges 31 are centrally symmetrical about the center line of the support rod 30, so that the stress of the two holding edges 31 is more uniform and balanced, and the inclination of the spacer 40 to either side is avoided.

As shown in fig. 5, the spacer 40 is provided in a disc shape having a through hole 41, and the support rod 30 passes through the through hole 41 with the holding edge 31 extending on the circular periphery of the spacer 40. The gasket 40 comprises a protrusion 43 facing the elastic member 50 in the middle and a circular ring 42 with a planar periphery, and the abutting edge 31 abuts against the surface of the circular ring 42. The protrusion 43 can be inserted into the circular hole of the spring, so that the positions of the gasket 40 and the elastic member 50 are relatively fixed, mutual sliding is avoided, the abutting edge 31 abuts against the surface of the circular ring 42, sinking into the groove on the other surface of the protrusion 43 is avoided, and the abutting edge 31 is in smoother contact with the gasket 40.

Further, the support rod 30 includes a rod 32, the rod 32 and the holding edge 31 are integrally disposed, and the holding edge 31 is connected to the rod 32 and is bent to the side.

Desirably, the abutting edge 31 is arc-shaped in accordance with the shape of the circular ring 42, and more desirably, the arc-shaped abutting edge 31 is semicircular, and the two abutting edges 31 enclose a circle. The abutting edge 31 can be bent to form a bevel edge in a tangential direction with the circular ring 42, and the extending length is enough to meet the requirement that the gasket 40 is not easy to deform, due to the limitation of process and processing difficulty.

As shown in fig. 6, the rod 32 is plate-shaped, and the abutting edge 31 forms an included angle smaller than 90 degrees with the plane of the rod 32. The abutting edge 31 thus bent may extend in a direction substantially tangential to the ring 42.

As shown in fig. 5 and 6, the two holding edges 31 may be a first holding edge 311 and a second holding edge 312, where the two holding edges 31 and the rod 32 have equal angles, one holding edge 31 is located on one side of the rod 32, and the other holding edge 31 is located on the other side of the rod 32. For example, the angle between the first abutting edge 311 and the left side surface of the rod body 32 is about 45 degrees, and the angle between the second abutting edge 312 and the right side surface of the rod body 32 is about 45 degrees, so that the cross sections of the first abutting edge 311, the rod body 32 and the second abutting edge 312 are approximately S-shaped, and the shape has the effects of more stable stress and larger contact area.

In addition, the supporting beam 20 is provided with a vertical hole, so that the movement direction of the supporting rod 30 can be limited, the supporting rod 30 is in contact with the supporting beam 20 and the sliding shaft, one side of the supporting rod 30 facing the sliding shaft is provided with a circular arc notch, and the upper and lower linear movement of the sliding shaft is combined, so that the plane of the plate body of the supporting rod 30 is always perpendicular to the direction of the box body connecting plate, as shown in fig. 3, that is, the front and rear directions are set, the first abutting edge 311 can extend from the front of the plate body, the left side is bent, the second abutting edge 312 extends from the rear of the plate body, the right side is bent, and the left side and the right side can be interchanged.

The gasket 40 may be made of metal, and referring to fig. 1 and 2 of the related art, the conventional gasket 12 is abutted against the protrusions 111 of the supporting rod 11 from the front and rear ends of the through hole, but the left side or the right side of the through hole is not abutted against the supporting rod 11, that is, the front and rear ends are not abutted against the protrusions 111 above, so that the gasket 12 is bent into a V shape by the left and right sides, at this time, the left side or the right side of the gasket 12 is higher, even both sides are higher than the middle, the upper end surface of the elastic member obviously cannot be higher at the same time, only one side is higher, which results in that the upper end surface of the elastic member is not in a horizontal state, but in a curved state, the curved elastic member presses the supporting rod 11 to block the movement, and the extrusion of the supporting rod 11 and the elastic member can generate noise in the up-down movement process.

In this embodiment, the first abutting edge 311 abuts against the upper side of the left gasket 40, the second abutting edge 312 abuts against the upper side of the right gasket 40, and the upward bending of the two sides of the gasket 40 is avoided, so that the gasket 40 can be kept straight, and the gasket 40 can be kept horizontal, so that the elastic member 50 is kept vertical instead of in a bending state because the gasket 40 is straight and the first abutting edge 311 and the second abutting edge 312 are symmetrical. The elastic member 50 is relatively parallel to the support bar 30, and the elastic member 50 does not press the support bar 30 in the horizontal direction, thereby avoiding noise.

In addition, the surface of the spacer 40 away from the elastic member 50 is not in contact with the rod body 32, and the surface of the abutting edge 31 in contact with the spacer 40 is a plane, so as to ensure better contact between the abutting edge 31 and the spacer 40, avoid the existence of the point of the local protrusion 43, and prevent the whole surface of the abutting edge 31 from being in good contact with the surface of the spacer 40.

Compared with the prior art, the embodiment has the following beneficial effects:

according to the hinge 100, the structure of the supporting rod 30 is improved, the extending supporting edge 31 extends on the periphery of the gasket 40, so that the supporting edge has a larger contact area with the gasket 40, the original bulge 43 is almost in point contact to be in surface contact, the stress of the gasket 40 is uniform, the possibility of deformation of the gasket 40 is reduced, and the elastic piece 50 can be better kept in a vertical state in the hinge 100 because the gasket 40 is not deformed, so that the problem that the elastic piece 50 bends to press the supporting rod 30 to give out abnormal sound is avoided, and the use experience of a user is improved.

It should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate embodiment, and that this description is for clarity only, and that the skilled artisan should recognize that the embodiments may be combined as appropriate to form other embodiments that will be understood by those skilled in the art.
