Detailed Description

Reference is made to the accompanying drawings. The invention provides a hinge which comprises a first component 1 and a second component 2, wherein the first component 1 and the second component 2 are arranged up and down. The first part is approximately of a plate-shaped structure, and a main body structure can be formed by processing a metal plate through sheet metal; the second part 2 is a plate-frame structure, which can be formed by sheet metal processing of a metal plate to form a main structure, but the middle part is basically hollowed out to leave a frame strip, and the structures of the two parts can be interchanged. The middle part of the second part 2 can be also provided with a connecting frame 3, the connecting frame 3 is of a roughly plate-shaped structure, a main body structure can be formed by metal plates through sheet metal processing, and the middle connecting frame 3 can increase the strength of the second part 2 and is also convenient for the configuration of an elastic locking mechanism and the stability of heavy load wide and large size sliding.

Set up between first part 1 and the second part 2 guide mechanism of both relative sliding, this guide structure can include sharp limit 21 and groove 11, and sharp limit 21 can set up the limit portion at the second part, through the panel beating shaping, and groove 11 can set up the limit portion at the first part, through the panel beating shaping, can set up in groove 11 with sharp limit 21 complex spout strip 4.

Left and

right spring mechanisms

51, 52 are provided between the first member 1 and the second member 2. The

spring mechanisms

51, 52 may be springs, and both ends of the springs are connected with the first member 1 and the second member 2 through the connection structures, respectively. The

spring mechanisms

51 and 52 may be configured by combining springs and connecting frames that can slide relative to each other.

The left and right spring means 51, 52 are preferably symmetrically arranged spring means.

As shown in fig. 1, 3, and 4, the hinge is configured with a first stop position, a second stop position, and a third stop position, where in different stop positions, there are different relative positions between the first component 1 and the second component 2, and the first stop position and the third stop position are two end limits of the relative sliding stroke in different directions, which can be limited by a stop provided on the hinge, a stop provided on an applied electronic device, and the like, to prevent the first component 1 or the second component 2 from sliding any more after reaching the end.

The second stop position is located between the first stop position and the third stop position and is a middle stop position, and the hinge is provided with an elastic locking mechanism for the second stop position. The spring means 51, 52 are arranged such that in the second rest position there is no force component on the sliding path defined by the guide means (the runner strip 4 and the straight edge 21), or even if there has to be a force component due to play, error, backlash, etc., but very little, and in the first and third rest positions the spring means 51, 52 have a force component in the direction of the sliding path which both urges the first and second parts to slide relative to each other in a direction away from the second rest position. The spring means 51, 52 may be arranged such that a line connecting the two ends of the spring means is inclined to the sliding path in the first and third rest positions and substantially perpendicular to the opposite sliding path in the second rest position.

The elastic locking mechanisms are respectively arranged between the left side and the right side of the connecting frame 3 and the first component. The elastic locking mechanism comprises a spring 61 and a part 620 with a convex part 62, one end of the part 620 is connected with the spring 61, the spring 61 is connected with the first part 1, the second part 2 is provided with a positioning groove 31 matched with the convex part 62, and in the embodiment, the connecting frame 3 is provided with the positioning groove 31 as a part of the second part. Alternatively, the elastic locking mechanism may also be an elastically driven movement mechanism with a pin.

On the first member 1, a slide guide structure of the member 620, which may be a guide groove 12, is provided, and the member 620 is provided with a portion 621 that engages with the guide groove 12.

Further, a relative sliding guide structure is arranged between the connecting frame 3 and the first component 1 and is matched with the sliding guide structure of the component 620, so that when the first component 1 and the second component 2 slide relatively, the elastic locking mechanism can work more accurately and the stability of heavy load wide and large size sliding is improved. The guiding structure may be a straight edge 32 formed by a metal plate on the connecting frame 3, and the groove 31 is located on the straight edge 32. A guide slope 33 having a mouth of the groove 31 slightly protruding from the linear side 32 and a projection 62 between the linear side 32 and the mouth; the guide structure further comprises a groove 13 arranged in the middle of the first component 1, the groove 13 is also formed by sheet metal, and a sliding groove strip 7 in sliding fit with the linear edge 32 can be arranged in the groove 13.

A guide and limit mechanism for the relative sliding of the first component 1 and the second component 2 can be arranged between the middle frame 3 and the first component 1, so that the first component 1 or the second component 2 is limited to reach the stroke end points of the relative sliding in two different directions and not to slide any more (a first parking position and a third parking position). The guiding and limiting mechanism can be composed of a guiding and limiting groove 34 and a component (such as a rivet 8) which is matched with the guiding and limiting groove 34 in a sliding and limiting way, the guiding and limiting groove 34 can be arranged on the middle frame 3, and the rivet 8 is fixed on the first component 1. Thus, the smoothness of the wide-size sliding of the heavy load is improved and the first parking position and the third parking position are provided.

In the embodiment of fig. 1-5, the second docking station is configured to locate a point on the relative sliding trajectory of the first and second components 1, 2.

As shown in fig. 6-8, the second docking station may also be configured as a docking area in which the relative position of the first part 1 and the second part 2 is adjustable.

As shown in fig. 6, the groove bottom 310b of the positioning groove 31b is a flat bottom, so that a certain relative sliding stroke is formed between the groove bottom and the convex part 62 along the relative sliding direction, and the spring 61 acts on the component 620, so that the groove bottom and the convex part 62 are tightly pressed to generate friction force, the friction force not only can provide operation feeling, but also can have the function of stopping applying external force at any time to position the relative position of the first component and the second component at any time under the condition of heavy load matching, and the spring mechanism is arranged to have no component force or component force approaching to no component force on the sliding track defined by the guide mechanism in the second parking position, so that a user can conveniently adjust the position defined by the second parking position within a certain range.

As shown in fig. 7 and 8, there are several positioning matching positions between the movable pin or the protrusion and the positioning groove along the direction of the relative sliding, in fig. 7, there are several protrusions 62 along the sliding track of the first member 1 and the second member 2 on the member 620, and the groove 31 also has several positioning points along the sliding track, so that there are several positioning points within a certain range. Alternatively, in fig. 8, the projection 62 is one and the recess 31 is plural. In this way, it is convenient for the user to adjust the position defined by the second parking position within a certain range.

The above description is only an embodiment of the present invention, but the structural features of the present invention are not limited thereto, and any changes or modifications within the scope of the present invention by those skilled in the art are covered by the present invention.
