The embodiment of the utility model provides an in, design a moment of torsion hinge, according to above-mentioned moment of torsion hinge, can reach the effect of adjusting the required power in position of adjusting the device of installing on this moment of torsion hinge as required.

Fig. 3 is a front view of the torque hinge shown in fig. 1. FIG. 4 is a cross-sectional view taken along A-A of the torque hinge shown in FIG. 3.

Referring to fig. 1 and 2, the torque hinge 1 includes a fixed member and a pair of hinge modules, i.e., a first hinge module 3 and a second hinge module 3'. The fixing member is used for fixing the first hinge module 3 and the second hinge module 3 ', and the first hinge module 3 and the second hinge module 3' are respectively connected to two ends of the fixing member. The torque hinge 1 may further include a mount 4 disposed on the fixture for mounting/fixing the fixture, and particularly, the mount 4 may include a mounting hole. The mounting 4 may be formed integrally with the fixing or both may be mechanically connected or welded.

In a preferred embodiment, as shown in fig. 1, the fixing member is a hinge bushing 2, and a portion of the first hinge module 3 and a portion of the second hinge module 3' are respectively disposed in the shaft holes 2-1 of the hinge bushing 2 and are respectively assembled at both ends of the hinge bushing 2. The mounting member 4 is disposed on the hinge boss 2, for example, the mounting member 4 may be integrally formed with the hinge boss 2, preferably with the mounting hole of the mounting member 4 in an axial perpendicular relationship with the shaft hole 2-1 of the hinge boss 2. The mounting 4 serves for mounting/fixing the hinge bush 2, for example by fixing or hinging the torque hinge to a column via a mounting hole. As shown in fig. 1 and 2, the first hinge module 3 and the second hinge module 3' are respectively rotatably connected to the hinge bushing 2.

In another preferred embodiment, the fixing member is a hinge shaft (not shown), the first hinge module 3 and the second hinge module 3 'are respectively rotatably connected to two ends of the hinge shaft, for example, the hinge shaft has a first shaft end and a second shaft end which are oppositely arranged, the first hinge module 3 is rotatably connected to the first shaft end, and the second hinge module 3' is rotatably connected to the second shaft end. The mounting member 4 is placed on the hinge axis similarly to the arrangement of the mounting member of the hinge bush in the above preferred embodiment, for example, the mounting member 4 may be formed integrally with the side wall of the hinge axis, preferably with the mounting hole of the mounting member 4 in an axial perpendicular relationship with the hinge axis. The mounting 4 is used for mounting/fixing a hinge shaft, such as a torque hinge fixed or hinged on a pillar through a mounting hole.

The above embodiments show two different implementations of the fixing member, including the hinge bushing and the hinge shaft, however, it should be noted that the fixing member is not limited to the implementations shown in the above embodiments. The main function of the fixing element is to provide the first hinge module 3 and the second hinge module 3 ', and those skilled in the art can conceive other implementations of providing the first hinge module 3 and the hinge module 3' under the teaching of the above embodiments, which belong to the protection scope of the present application. In addition, the mounting component 4 for fixing the fixing component is not limited to the implementation shown in the drawings, and as long as the fixing component can be fixed, other implementations of the mounting component can be conceived by those skilled in the art under the teaching of the embodiments of the present application, and these implementations all belong to the protection scope of the present application. As shown in fig. 2, the first hinge module 3 includes a unidirectional rotation mechanism 31, half shafts 32, a link plate 33, and a clamp 34. The structural composition of the second hinge module 3' is the same as that of the first hinge module 3.

Fig. 5 is a structural schematic diagram of a unidirectional rotation mechanism of the torque hinge. A unidirectional rotation mechanism is a mechanism that can rotate freely in one direction and lock in the other direction. In a preferred embodiment, the unidirectional rotation mechanism comprises a unidirectional bearing. One-way bearings, also known as overrunning clutches, typically include a plurality of rollers, needles or balls within a metal housing, with the rolling seats (pockets) being shaped so that they roll in one direction only, but create significant resistance in the other direction, thereby forming a so-called "one-way". As shown in fig. 2 and 4, the fixing member is embodied as a hinge bushing 2, and the unidirectional rotation mechanism 31 is assembled in the shaft hole 2-1 of the hinge bushing 2, so that the hinge module 3 is rotatably connected with the hinge bushing 2. When the fixing member is a hinge shaft, the one-way rotating mechanism 31 can be sleeved on the hinge shaft, for example, one end of the hinge shaft, so that the first hinge module 3 is connected to one end of the hinge shaft, and the second hinge module 3' is connected to the other end of the hinge shaft. According to one embodiment of the invention, the unidirectional rotation mechanism of the first hinge module 3 and the one end connection 3' of the hinge shaft has opposite free rotation directions in said shaft hole.

FIG. 6 is a schematic diagram of the construction of the half-shafts of the torque hinge. As shown in FIG. 6, the axle shaft 32 includes a first shaft segment 32-1, a second shaft segment 32-2, and a shoulder 32-3 between the first shaft segment 32-1 and the second shaft segment 32-2. When the fixing member is embodied as a hinge bushing, as shown in fig. 2, the unidirectional rotation mechanism 31 is fitted in the shaft hole 2-1 of the hinge bushing 2, and the first shaft section 32-1 of the half shaft 32 is fitted in the unidirectional rotation mechanism 31 and is restrained by the shoulder 32-3. When the fixed piece is a hinge shaft, the one-way rotating mechanism 31 is sleeved on the end part of the hinge shaft, and the first shaft section 32-1 of the half shaft 32 is sleeved outside the one-way rotating mechanism 31 and limited by the shaft shoulder 32-3. To prevent or reduce wear caused by metal friction between the unidirectional rotation mechanism 31 and the half shaft 32, a retainer ring 35 may be placed between the unidirectional rotation mechanism 31 and the half shaft 32, with a corresponding retainer ring being located between the shoulder 32-3 and the side wall of the unidirectional rotation mechanism facing the shoulder 32-3. As shown in fig. 2, a connecting plate 33 and a clamping member 34 are sequentially inserted into the second shaft section 32-2 of the half shaft 32. By tightening the clamping element 34, a clamping of the connection plate 33 is formed. The same external load is clamped by the connecting plates 33 respectively arranged at the two ends of the hinge shaft sleeve or the hinge shaft, so that the half shafts at the two ends are positioned on the hinge shaft sleeve or the hinge shaft and cannot fall off from the hinge shaft sleeve or the hinge shaft.

FIG. 7 is a schematic structural view of a web of a torque hinge. As shown in fig. 7, the connection plate 33 includes a plug hole 33-1 and a connection assembly 33-2, and specifically, as shown in fig. 7, the connection assembly 33-2 may include a connection hole, and the plug hole 33-1 and the connection assembly 33-2 may be integrally formed. Wherein, the plug hole 33-1 of the connecting plate 33 is plugged on the second shaft section 32-2 of the half shaft 32. Through the connection assembly 33-2 of the connection plate 33, a device such as a display or a lighting lamp can be installed as a load. Specifically, the load may be collectively installed through the connection holes of the connection assembly 33-2 of the connection plates disposed at both sides of the hinge shaft sleeve or the hinge shaft.

The connecting assembly 33-2 of the connecting plate 33 for mounting a device such as a display or a lighting lamp as a load is not limited to the implementation shown in the drawings, and other implementations of the connecting assembly 33-2 of the connecting plate 33 can be conceived by those skilled in the art based on the teachings of the embodiments of the present application as long as the torque hinge can be fixed, and these implementations are all within the scope of the present application.

In one embodiment, as shown in FIG. 2, clamp 34 includes a resilient member 341 and a nut 342. The corresponding location of the second shaft segment (e.g., the end of the second shaft segment) has threads that mate with the nut 342. The clamping force is generated on the link plate 33 by the elastic member 341 of the half shaft 32 and the clamp 34 by applying a force to the link plate 33 via the elastic member 341 by the nut 342, and the magnitude of the clamping force is adjusted by adjusting the nut 342. In a preferred embodiment, the elastic member 341 may be a disc spring assembly.

The connection manner of the second hinge module 3 'and the shaft hole 2-1 and the structure of the second hinge module 3' may be substantially the same as those of the first hinge module 3. The first hinge module 3 is different from the second hinge module 3' in that the rotation directions of the two unidirectional rotation mechanisms are different. Therefore, when the load rotates, one half shaft is always in a non-resistance rotating state, and the other half shaft is in a locking state, so that a large resistance is formed to the rotation of the load.

With respect to the side where the unidirectional rotation mechanism is locked, as shown in fig. 2, the link plate 33 is clamped between the axle shaft 32 and the clamp 34 due to the axial pressure generated by the clamp 34, and therefore static friction is generated between the link plate 33 and the axle shaft 32 and the clamp 34 when the link plate 33 has a tendency to rotate relative to the axle shaft. When the external force is smaller than the static friction force, the connecting plate 33 keeps the position unchanged; the rotation of the link plate 33 can only occur when the external force is greater than the frictional force. With this characteristic, when the torque generated by the load on the link plate 33 is smaller than the torque of the frictional force, the link plate 33 does not rotate with respect to the hinge boss 2. For example, a cantilever is connected to the connecting plate, and the cantilever can be kept in place as long as the weight of the cantilever and the device at the end of the cantilever is less than the torque of the friction force. The cantilever can move after external force is applied to break balance; the device can be kept still after force application is stopped, thereby having the function similar to 'suspension'.

In addition, the pressure of the clamping pieces 34 on the two half shafts can be respectively and independently adjusted, and the pressure between the two connecting plates 33 and the half shafts 32 and the clamping pieces 34 can be the same or have a certain difference value according to requirements, so that different rotation directions have different damping. For example, when adjustment of the up-down height is required, the adjustment

The respective nuts 342 of the first hinge module 3 and the second hinge module 3' make the opposing damping smaller when pushing up the load than when pulling down the load, so as to counteract the influence of the load gravity, make the force applied by the operator when pushing up or pulling down the load substantially consistent, and facilitate control.

In a preferred embodiment, shown in FIG. 2, a spacer 36 is disposed in the socket 33-1, the spacer 36 being effective to prevent or reduce wear caused by friction between the web 33 and the second shaft section 32-2 of the axle shaft 32. Preferably, the spacer sleeve 36 has a profile that matches the shape of the plug aperture 33-1. The web 33 is mounted to the second shaft section 32-2 of the axle shaft 32 by a spacer sleeve 36. As shown in FIG. 2, the bore of the spacer sleeve 36 is adapted to receive the second shaft segment 32-2. FIG. 8 is a schematic view of the spacer of the torque hinge. As shown in FIG. 8, the cross-sectional shape and size of the bore of the spacer sleeve 36 preferably substantially matches the cross-section of the second shaft section 32-2 to provide a better circumferential stop. The spacer sleeve may be made of plastic or other materials.

In another preferred embodiment, as shown in FIG. 2, a first shim 37 is inserted into the side of the web 33 adjacent to the shoulder 32-3 of the axle shaft 32, and the first shim 37 is effective to prevent or reduce wear caused by friction between the web 33 and the shoulder 32-3 of the axle shaft 32. Likewise, in order to prevent or reduce wear caused by friction between the connection plate 33 and the clamping element 34, a first shim 37' may also be inserted on the side of the connection plate 33 facing the clamping element 34. As shown in fig. 2, the holes in the first washers 37, 37' are used for plugging the second shaft section 32-2. Fig. 9 is a schematic view of a first shim of the torque hinge. As shown in FIG. 9, the cross-sectional shape and size of the first spacer 37 hole preferably matches the cross-section of the second shaft section 32-2 to provide a better circumferential stop. The first gasket is preferably a brass graphite gasket, but may be a gasket of other material, such as a stainless steel gasket, a copper gasket, etc., as long as it provides the required frictional force.

The connection manner of the second hinge module 3 'and the shaft hole 2-1 and the structure of the second hinge module 3' may be substantially the same as those of the first hinge module 3. The important difference between the first hinge module 3 and the second hinge module 3' is that the rotation directions of the respective unidirectional rotation mechanisms are different. Thus, when the load is rotating, there is always one half-shaft rotating without resistance, while the other half-shaft is locked and cannot rotate.

Thus, on the side where the unidirectional rotation mechanism is locked, as shown in fig. 2, there is axial pressure generated by the clamping piece 34 between the link plate 33 and the first washers 37, 37 ', and therefore static friction is generated between the link plate 33 and the first washers 37, 37' when the link plate 33 has a tendency to rotate relative to the half shaft. When the external force is smaller than the static friction force, the connecting plate 33 keeps the position unchanged; the rotation of the link plate 33 can only occur when the external force is greater than the frictional force. In addition, the pressure of the clamping elements 34 on the two half-shafts can be adjusted individually, and the pressure between the two connecting plates 33 and the first washers 37, 37' can be made the same or have a certain difference, as required, so as to have different damping for different directions of rotation.

In a preferred embodiment, as shown in fig. 2, a second spacer 38 may be inserted on the side of the clamping member 34 adjacent to the connecting plate 33 in order to allow the clamping member 34 to uniformly apply pressure to the connecting plate 33. In addition, in the case where the clamping member 34 is the elastic member 341 and the nut 342, in order to allow the nut 342 to uniformly apply pressure to the elastic member 341 and prevent abrasion therebetween, a second gasket 38' may be inserted on a side of the nut 342 closer to the elastic member. The material of the second gasket 38, 38' includes, but is not limited to, copper, stainless steel, etc.

According to the torque hinge, the effect of adjusting the force required for adjusting the position of the device mounted on the torque hinge according to the requirement can be achieved. For example, the effect of individually adjusting the forward and reverse forces required by the devices mounted on the torque hinge as needed can be achieved.
