Description

Technical Field

[0001] This application relates to the field of monitor stand technology, and in particular to a tilt adjustment component for a monitor stand. Background Technology

[0002] In existing technology, the tilt adjustment component of a monitor stand is used to adjust the monitor's tilt angle, and its adjustment and locking mostly rely on the friction between the components. When a heavy monitor is hung on the tilt adjustment component, if it still relies solely on the contact friction between the hinges for locking, the friction is often insufficient to lock the monitor securely, resulting in the monitor drooping. Even if it can be locked in place with difficulty, a large amount of friction is required between the hinges, but excessive friction makes it very difficult for users to adjust the monitor's tilt angle, resulting in a poor user experience. Utility Model Content

[0003] This application provides a tilt adjustment component for a monitor stand, which at least solves the technical problem of insufficient friction in the tilt adjustment component of a monitor stand in the related art.

[0004] To achieve the above objectives, this application provides a tilt adjustment assembly for a monitor stand, including a mounting base connected to the monitor and a rotating member connected to the stand. The mounting base is provided with a mounting portion, and the rotating member is rotatably mounted within the mounting portion. The rotating member is provided with a movable wheel that can move axially along a rotation axis and an elastic member that causes the movable wheel to have a tendency to return to its original position after movement. The movable wheel is provided with a first helical surface, and the mounting portion is provided with a second helical surface that cooperates with the first helical surface. When the mounting base rotates relative to the rotating member, the second helical surface pushes the first helical surface to cause the movable wheel to move axially along the rotation axis.

[0005] In some embodiments, the movable wheel includes a left movable wheel and a right movable wheel disposed within the rotating member, and the elastic member is disposed between the left movable wheel and the right movable wheel.

[0006] In some embodiments, the first helical surface is respectively disposed on the side of the left movable wheel and the right movable wheel away from the elastic member, and the second helical surface is respectively disposed at the left and right ends of the mounting portion.

[0007] In some embodiments, the mounting portion is provided with a detachable left fixed wheel and a right fixed wheel at its left and right ends, respectively, and the second helical surface is provided on the left fixed wheel and the right fixed wheel.

[0008] In some embodiments, the left fixed wheel and the right fixed wheel are respectively provided with positioning parts, and the mounting part is provided with a first positioning groove. The positioning parts cooperate with the first positioning groove to fix the left fixed wheel and the right fixed wheel relative to the mounting part.

[0009] In some embodiments, the left movable wheel and the right movable wheel are provided with guide ribs in the circumferential direction, and the rotating member is provided with a guide groove extending axially and cooperating with the guide ribs.

[0010] In some embodiments, the left movable wheel and the right movable wheel are respectively provided with a second positioning groove on the side near the elastic member, and the elastic member is positioned in the second positioning groove.

[0011] In some embodiments, the mounting portion is connected to the rotating member by bolts.

[0012] In some embodiments, the bolt passes sequentially through the left fixed wheel, the left movable wheel, the elastic element, the right movable wheel, and the right fixed wheel, and is secured by a nut.

[0013] In some embodiments, the mounting base is detachably connected to the mounting portion.

[0014] Based on the above, the beneficial effects of the technical solution in this application are:

[0015] When the mounting base rotates relative to the rotating part, it pushes the movable wheel toward the center of the rotating part. After the elastic element is compressed, it applies a reverse thrust to the movable wheel, causing the movable wheel to press against the fixed wheel. Thus, the force of the elastic element increases the friction. Attached Figure Description

[0027] This application provides a tilt adjustment assembly for a monitor stand, including a mounting base connected to the monitor and a rotating member connected to the stand. The mounting base is provided with a mounting part, and the rotating member is rotatably mounted in the mounting part. The rotating member is provided with a movable wheel that can move along the axis of rotation and an elastic member that causes the movable wheel to have a tendency to return to its original position after movement. The movable wheel is provided with a first helical surface, and the mounting part is provided with a second helical surface that cooperates with the first helical surface. When the mounting base rotates relative to the rotating member, the second helical surface pushes the first helical surface to make the movable wheel move along the axis of rotation.

[0028] Implementation, for example Figures 1-6 As shown, a tilt adjustment assembly for a monitor stand includes a mounting base 1 connected to the monitor and a rotating component 2 connected to the stand. The mounting base 1 is provided with a detachable mounting part 1.1, and the rotating component 2 is rotatably installed in the mounting part 1.1 and fixedly connected by bolts 3.1 and nuts 3.2.

[0029] Furthermore, the rotating component 2 is provided with a left movable wheel 4.1 and a right movable wheel 4.2 that can move along the axis of rotation. An elastic element 5 (in this embodiment, the elastic element 5 is a spring) is provided between the left movable wheel 4.1 and the right movable wheel 4.2. The elastic element 5 gives the left movable wheel 4.1 and the right movable wheel 4.2 a tendency to return to their original position after movement. The left and right ends of the mounting part 1.1 are respectively provided with a detachable left fixed wheel 6.1 and a right fixed wheel 6.2. The left fixed wheel 6.1 and the right fixed wheel 6.2 can rotate with the mounting part 1.1 and are fixed relative to the mounting part 1.1. The bolt 3.1 passes through the left fixed wheel 6.1, the left movable wheel 4.1, the elastic element 5, the right movable wheel 4.2 and the right fixed wheel 6.2 in sequence, and is fixed by the nut 3.2.

[0030] Specifically, the left fixed wheel 6.1 and the right fixed wheel 6.2 are respectively provided with positioning parts 6.3 in the circumferential direction, and the mounting part 1.1 is provided with a first positioning groove 1.1.1. The positioning part 6.3 is inserted into the first positioning groove 1.1.1 to fix the left fixed wheel 6.1 and the right fixed wheel 6.2 relative to the mounting part 1.1.

[0031] Furthermore, the left movable wheel 4.1 and the right movable wheel 4.2 are provided with a first helical surface 4.3 on the side away from the elastic member 5. The left fixed wheel 6.1 is provided with a second helical surface 6.4 that mates with the first helical surface 4.3 on the side near the left movable wheel 4.1, and the right fixed wheel 6.2 is provided with a second helical surface 6.4 that mates with the first helical surface 4.3 on the side near the right movable wheel 4.2. When the mounting base 1 rotates relative to the rotating member 2, the second helical surface 6.4 on the left fixed wheel 6.1 and the right fixed wheel 6.2 rotates and pushes the first helical surface 4.3, thereby causing the left movable wheel 4.1 and the right movable wheel 4.2 to move axially along the axis of rotation.

[0032] Specifically, the left movable wheel 4.1 and the right movable wheel 4.2 have guide ribs 4.4 formed in the circumferential direction, and the rotating part 2 has a guide groove 2.1 extending in the axial direction. The guide ribs 4.4 and the guide groove 2.1 cooperate so that the left movable wheel 4.1 and the right movable wheel 4.2 will not rotate when facing the second helical surface 6.4, but will only move in the axial direction.

[0033] Specifically, the left movable wheel 4.1 and the right movable wheel 4.2 are respectively provided with a second positioning groove 4.5 on the side near the elastic member 5, and the elastic member 5 is positioned in the second positioning groove 4.5.

[0034] Working Principle: When adjusting the monitor's tilt angle, the mounting base 1 drives the mounting part 1.1 to rotate relative to the rotating component 2, and the left fixed wheel 6.1 and right fixed wheel 6.2 rotate synchronously with the mounting part 1.1. The second helical surface 6.4 on the left fixed wheel 6.1 abuts against the first helical surface 4.3 on the left movable wheel 4.1, and the second helical surface 6.4 on the right fixed wheel 6.2 abuts against the first helical surface 4.3 on the right movable wheel 4.2. Because the guide rib 4.4 on the movable wheel engages with the guide groove 2.1 in the rotating component 2, the left movable wheel 4.1 and right movable wheel 4.2 are not pushed to rotate by the second helical surface 6.4, but are pushed towards the center of the rotating component 2, thereby compressing the elastic element 5 located between the left movable wheel 4.1 and right movable wheel 4.2. After the elastic element 5 is compressed, it will give the left movable wheel 4.1 and right movable wheel 4.2 a reverse thrust, causing them to tend to return to their original position, resulting in increased contact pressure between the movable wheel and the fixed wheel, and thus increased rotational friction. The greater the rotation angle of the mounting base 1, the longer the movement path of the movable wheel toward the middle of the rotating part 2, the more severe the compression of the elastic element 5, the greater the reverse thrust of the elastic element 5 on the movable wheel, and thus the greater the friction between the mounting base 1 and the rotating part 2.

[0035] Those skilled in the art should understand that the technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments have been described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
