Description

Technical Field

[0001] This invention relates to the field of electronic equipment technology, and more particularly to a hinge mechanism and a display bracket for a console. Background Technology

[0002] A monitor stand is used to support a monitor and adjust its spatial orientation. The monitor stand mainly includes at least two support arms, a hinge mechanism for hinged connection between adjacent support arms, and the monitor mounted on the free end of the distal support arm. The hinge mechanism allows the support arms to rotate to adjust the monitor's spatial orientation and also keeps the rotated support arms at the rotated angle. Therefore, existing hinge mechanisms typically include: a spindle, a damping sleeve (or friction sleeve), an outer sleeve, and a preload component. The spindle is mounted on the end of one support arm and rotates synchronously with it. The outer sleeve is mounted on the end of the other support arm. The damping sleeve is housed within the outer sleeve and rotates synchronously with it. The spindle passes through the damping sleeve, and the preload component adjusts the preload force between the spindle and the damping sleeve. During the adjustment of the angle of the two support arms, the dynamic friction between the outer peripheral surface of the spindle and the inner wall of the damping sleeve provides damping (dynamic damping), which provides resistance when the support arms are rotated. After rotation, the static friction between the outer peripheral surface of the spindle and the inner wall of the damping sleeve provides damping (static damping), which is used to keep the support arms at the adjusted angle, thereby keeping the display at the adjusted spatial posture. Furthermore, the preload component adjusts the damping between the outer peripheral surface of the spindle and the inner wall of the damping sleeve by adjusting the preload force between them.

[0003] However, the aforementioned hinge mechanism in the prior art provides damping solely through friction between two surfaces, that is, solely through friction between the outer circumferential surface of the spindle and the inner wall of the damping sleeve. This will at least lead to the following problems: The dynamic damping (dynamic friction) experienced by the support arm when rotating in both directions is basically equal and cannot be adjusted independently. Furthermore, the static damping (static friction) experienced by the support arm when it is stationary is basically equal to (slightly greater than) the dynamic damping, and the dynamic damping and static damping are positively correlated. That is, when the preload increases the dynamic damping, the static damping also increases synchronously. This leads to the following result: In a certain direction of rotation, for example, in an upward direction of rotation, the goal of keeping the support arm stably at the adjusted angle and the goal of making the support arm easy to rotate can only satisfy one of the two. That is to say, if the static damping is increased to improve the stability, the dynamic damping will increase simultaneously, causing the support arm to be unable to be easily rotated, and vice versa.

[0026] To keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of known functions and known components are omitted.

[0027] like Figures 1 to 7 As shown, an embodiment of the present invention discloses a hinge mechanism 100 and a display bracket for a console including the hinge mechanism 100. The bracket further includes a first support arm and a second support arm. The hinge mechanism 100 is disposed between the first support arm and the second support arm to enable the first support arm and the second support arm to be hinged, that is, the first support arm and the second support arm can rotate relative to each other through the hinge mechanism 100. Figure 1 As shown, the display 200 is mounted on the distal end of the second support arm via a mounting plate. The hinge mechanism 100 provided by the present invention is particularly suitable for situations where the tilt angle or height of the display 200 is adjusted by vertically rotating the second support arm, while the first support arm remains fixed. Thus, the first support arm may be referred to as the base arm 101, and the second support arm as the movable arm 102. The first rotation direction of the first support arm is upward rotation, and the second rotation direction is downward rotation.

[0028] like Figure 2 As shown, the hinge mechanism 100 includes: a first end 10, a second end 20, a spindle 30, a damping sleeve 40, an outer bushing 51, an inner bushing 52, a first locking nut 61, and a second locking nut 62.

[0029] The first end 10 is formed at the end of the base arm 101, and the second end 20 is formed at the end of the movable arm 102. The first end 10 and the second end 20 are arranged side by side. The inner end of the first end 10 and the inner end of the second end 20 are connected by a conical surface, and a wear-resistant plate 65 is provided in the connection area. The wear-resistant plate 65 makes the first end 10 and the second end 20 form a certain connection gap.

[0030] The first end 10 has a positioning hole 11, and the second end 20 has a guide hole 21. The positioning hole 11 and the guide hole 21 are coaxial, and the positioning hole 11 is configured as a flat round hole. The spindle 30 passes through the positioning hole 11 and the guide hole 21. The tail of the spindle 30 is located in the positioning hole 11, and the head of the spindle 30 is located on one side of the second end 20. The tail of the spindle 30 is configured as a flat column 31, which cooperates with the positioning hole 11. In this way, the spindle 30 is restricted from rotating by the first end 10.

[0031] The guide hole 21 is configured as a tapered hole, and the radial dimension of the outer end of the guide hole 21 is greater than the radial dimension of the inner end; the outer bushing 51 is a metal sleeve, the inner hole of the outer bushing 51 is a circular hole, the outer circumferential surface of the outer bushing 51 is configured as a tapered surface, the outer bushing 51 is installed in the guide hole 21 and the outer circumferential surface of the outer bushing 51 is engaged with the tapered surface of the inner hole wall of the guide hole 21; the outer bushing 51 and the guide hole 21 are also configured to be keyed, so that the outer bushing 51 can only move axially relative to the guide hole 21 and restricts the outer bushing 51 from rotating relative to the second end 20.

[0032] The first locking nut 61 is installed on the outside of the guide hole 21 and forms a threaded engagement with the second end 20. By screwing the first locking nut 61, the first locking nut 61 is axially pushed against the outer bushing 51. The outer bushing 51 has a circumferentially arranged first slit 511 on its sleeve wall, which extends to the inner end of the outer bushing 51, thereby giving the outer bushing 51 the ability to deform radially. Thus, when the first locking nut 61 axially pushes against the outer bushing 51, the guide hole 21 forces the outer bushing 51 to deform radially inward by engaging with the tapered surface of the outer bushing 51.

[0033] The inner bushing 52 is a metal sleeve, which is disposed in the guide hole 21 and sleeved on the mandrel 30. The inner bushing 52 and the mandrel 30 are also configured to be keyed, so that the inner bushing 52 can only move axially relative to the mandrel 30 and restricts the rotation of the inner bushing 52 relative to the mandrel 30. The outer peripheral surface of the inner bushing 52 is cylindrical, and the inner hole of the inner bushing 52 is configured as a tapered hole. The shaft segment of the mandrel 30 corresponding to the inner bushing 52 is configured as a tapered column 33. The outer peripheral surface of the tapered column 33 is tapered, and the tapered surface is opposite to the tapered hole wall of the guide hole 21. The tapered surface of the mandrel 30 is engaged with the tapered surface of the tapered hole of the inner bushing 52.

[0034] The head of the mandrel 30 is equipped with a stud 32, a pressure cap 63, and a second locking nut 62, which are sleeved on the stud 32. The pressure cap 63 directly contacts the inner bushing 52, and the second locking nut 62 directly contacts the pressure cap 63. The second locking nut 62 and the stud 32 form a threaded engagement. Thus, by screwing the second locking nut 62, the pressure cap 63 is axially pushed against the inner bushing 52. The inner bushing 52 has circumferentially arranged second slits 521 on its sleeve wall, which extend to the inner end of the inner bushing 52, thereby giving the inner bushing 52 the ability to deform radially. Thus, when the second locking nut 62 axially pushes against the inner bushing 52, the tapered surface of the mandrel 30, through its engagement with the tapered hole of the inner bushing 52, forces the inner bushing 52 to deform radially outward. Preferably, the outer ends of the first end 10 and the second end 20 are both provided with detachable covers 64.

[0035] By screwing on the first locking nut 61, the outer bushing 51 is slightly moved axially, so that the guide hole 21 engages with the tapered surface of the outer bushing 51, forcing the sleeve wall of the outer bushing 51 to deform radially inward. This adjusts the preload between the inner wall of the outer bushing 51 and the outer circumferential surface of the damping sleeve 40, thereby adjusting the frictional force (including dynamic and static friction) between the two. By screwing on the second locking nut 62, the inner bushing 52 is slightly moved axially, so that the mandrel 30 engages with the tapered surface of the inner bushing 52, forcing the sleeve wall of the inner bushing 52 to deform radially outward. This adjusts the preload between the outer circumferential surface of the inner bushing 52 and the inner wall of the damping sleeve 40, thereby adjusting the frictional force (including dynamic and static friction) between the two.

[0036] A damping sleeve 40 is disposed between an outer bushing 51 and an inner bushing 52. The outer peripheral surface of the damping sleeve 40 and the inner wall of the outer bushing 51 are configured to form a first damping application structure 81, and the inner wall of the damping sleeve 40 and the outer peripheral surface of the inner bushing 52 are configured to form a second damping application structure 82. Specifically, the damping sleeve 40 includes a body 43 made of metal material, an outer vulcanized rubber layer 42 formed on the radially outer side of the body 43, and an inner vulcanized rubber layer 41 formed on the radially inner side of the body 43. The outer side of the outer vulcanized rubber layer 42 forms the outer peripheral surface of the damping sleeve 40, and the inner side of the inner vulcanized rubber layer 41 forms the inner wall of the damping sleeve 40. The first damping application structure 81 includes: a first groove 811 and a first rib 812; the first groove 811 includes a plurality of first grooves 811 arranged circumferentially on the outer vulcanized rubber layer 42 and extending axially; the first rib 812 includes a plurality of first ribs 812 arranged circumferentially on the inner wall of the outer bushing 51 and extending axially; the first groove 811 has a first stop surface 8111 and a first guide surface 8112, the first stop surface 8111 is used to stop the first rib 812, and the first guide surface 8112 is used to guide the first rib 812; the second damping application structure 82 includes: The second groove 821 and the second rib 822 are provided. The second groove 821 includes multiple second grooves, which are circumferentially arranged on the inner vulcanized rubber layer 41 and extend axially. The second rib 822 includes multiple second ribs, which are circumferentially arranged on the outer peripheral surface of the inner bushing 52 and extend axially. The second groove 821 has a second stop surface 8211 and a second guide surface 8212. The second stop surface 8211 is used to stop the second rib 822, and the second guide surface 8212 is used to guide the second rib 822. The first stop surface 8111 and the second stop surface 8211 have the same orientation.

[0037] Based on the above, we can conclude that: On the one hand, such as Figure 4 and combined Figure 3As shown, when the movable arm 102 is rotated upwards (i.e., when the movable arm 102 is rotated in the first rotation direction), the first stop surface 8111 of the first groove 811 stops the first protruding rib 812, thereby causing the damping sleeve 40 to rotate with the movable arm 102 and the second end 20. At the same time, the second protruding rib 822 slides out of the second groove 821 along the second guide surface 8212 of the second groove 821, thereby causing the damping sleeve 40 to rotate relative to the inner bushing 52 in the first rotation direction. At this time, the inner bushing 52 applies dynamic friction to the damping sleeve 40, and this dynamic friction serves as dynamic damping during the rotation of the movable arm 102; when When the movable arm 102 is rotated downwards (i.e., when the movable arm 102 is rotated in the second rotation direction), the second stop surface 8211 of the second groove 821 stops the second protruding rib 822, thereby restricting the damping sleeve 40 from rotating with the movable arm 102 and the second end 20 in the second rotation direction. At the same time, the first protruding rib 812 slides out of the first groove 811 along the first guide surface 8112 of the first groove 811, thereby the outer bushing 51 rotates relative to the damping sleeve 40 in the second rotation direction. At this time, the damping sleeve 40 applies dynamic friction to the outer bushing 51, and this dynamic friction serves as dynamic damping during the rotation of the movable arm 102.

[0038] On the other hand, when the movable arm 102 tends to rotate upward, the inner bushing 52 applies a static friction force in the second rotation direction to the damping sleeve 40. This static friction force is provided to the movable arm 102 as static damping to limit the upward rotation of the movable arm 102. When the movable arm 102 tends to rotate downward, the damping sleeve 40 applies a static friction force in the first rotation direction to the outer bushing 51. This static friction force is provided to the movable arm 102 as static damping to limit the downward movement of the movable arm 102.

[0039] As can be seen from the above, when the movable arm 102 rotates in different directions, the dynamic damping it experiences is provided by the dynamic friction between different surface groups (i.e., by the first damping application structure 81 and the second damping structure). Furthermore, when the movable arm 102 tends to rotate in different directions, the static damping it experiences is provided by the static friction between different surface groups. Thus, the static damping and dynamic damping corresponding to different rotation directions can be adjusted as needed.

[0040] The advantages of the hinge mechanism 100 described above will be illustrated below using the example of adjusting the height of the monitor 200: Understandably, the user can raise the display 200 by rotating the movable arm 102 upwards, and correspondingly, the user can lower the display 200 by rotating the movable arm 102 downwards.

[0041] The problem with the existing hinge mechanism 100 is that the movable arm 102 is damped by the dynamic friction of the same surface group when rotating in both directions. Therefore, the damping provided in both directions is approximately equal. Furthermore, the static friction provided by the same surface group is approximately equal to the dynamic friction, resulting in approximately equal static and dynamic damping. After raising the monitor 200, it needs to be maintained at the adjusted height. This necessitates that the static damping be able to resist the weight of the monitor 200. However, this inevitably leads to the need to apply a force greater than twice the weight of the monitor 200 to raise it.

[0042] The advantages of using the hinge structure provided by this invention are: The static damping that keeps the display 200 in the adjusted position and the dynamic damping that resists the rotation of the movable arm 102 are provided by two surface groups respectively. That is, the dynamic damping that resists the upward rotation of the movable arm 102 is provided by the second damping application structure 82, and the static damping that keeps the display 200 in the adjusted position is provided by the first application structure. In this way, the damping provided by the second damping application structure 82 can be adjusted to a level less than one gravitational equivalent, and theoretically the static damping can be adjusted to 0. The static damping provided by the first damping application structure 81 can be adjusted to a level greater than one gravitational equivalent. In this way, the user only needs to apply a force slightly greater than the weight of the display 200 to raise the display 200. After the raising is completed, the static damping provided by the first damping structure can keep the display 200 at the adjusted height.

[0043] In summary, the aforementioned hinge mechanism 100 allows the user to raise the monitor 200 with minimal force, and after raising it, the monitor 200 can be stably maintained in the adjusted position.

[0044] It should be noted that the static damping provided by the first damping application structure 81 and the second damping application structure 82 in the above-mentioned hinge mechanism 100 is approximately equal to the dynamic damping (the static damping is slightly greater than the dynamic damping). That is, for any surface group, the static damping provided is approximately equal to the dynamic damping provided.

[0045] like Figures 5 to 7As shown, in a preferred embodiment of the present invention, the hinge mechanism 100 further includes an elastic force-applying mechanism 70, which is disposed between the inner end of the guide hole 21 and the damping sleeve 40. The elastic force-applying mechanism 70 includes: a disc body 71, on which a first wave tooth 711 arranged circumferentially is disposed on the disc surface facing the inner end face 44 of the damping sleeve 40, and a second wave tooth that meshes with the first wave tooth 711 is disposed on the inner end face 44 of the damping sleeve 40; and an elastic member 72, which is disposed between the disc body 71 and the bottom of the guide hole 21 to provide elastic force to the disc body 71 so that the disc body 71 abuts against the damping sleeve 40 with a certain preload. Thus, during the transition of the damping sleeve 40 from a stationary state to rotation, the second wave tooth needs to disengage from the groove of the first wave tooth 711. This requires overcoming the elastic force of the elastic component 72 on the disc 71, and overcoming this force requires more resistance. Consequently, the damping sleeve 40 provides the movable arm 102 with additional, larger static damping. Once the second wave tooth disengages from the first wave tooth 711, the damping sleeve 40 no longer needs to overcome more resistance. Therefore, the damping sleeve 40 does not provide the movable arm 102 with additional, larger dynamic damping. This significantly increases static damping while the increase in dynamic damping is not significant. Consequently, the display 200 can maintain a more stable position at the adjusted height without significantly increasing the force required to drive the movable arm 102 to rotate. Preferably, the elastic component 72 comprises a plurality of stacked elastic rings.
