Description

Technical Field

[0001] This invention relates to the field of monitor stand technology, and more specifically to a computer monitor stand. Background Technology

[0002] A detachable monitor stand is a modular, detachable external support device used to replace the original monitor stand, suspending and fixing the screen to a desktop or wall, and supporting flexible adjustment of height, angle, and orientation.

[0003] For example, the patent document with authorization announcement number CN114658997B, authorization announcement date May 24, 2024, entitled "A Monitor Stand", includes a first column, a connector, a rotating arm assembly and an elastic element. The rotating arm assembly includes a first arm body that is hinged to the first column, and an elastic element, one end of which is connected to the first column. The technical solution of this invention can provide a monitor stand with a smaller size.

[0004] In existing technologies, elastic elements are generally used to balance the weight of the monitor in order to reduce the torque at the hinge of the stand. In this way, only a small amount of friction is needed to fix the hinge of the stand. However, in actual operation, the height of the monitor is often fixed first, and then the tension of the spring is adjusted. This has a problem: it is not possible to directly observe whether the tension of the spring and the weight of the monitor are balanced. Summary of the Invention

[0005] The purpose of this invention is to provide a computer monitor stand to overcome the aforementioned shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A computer monitor stand includes a vertical pole and a connecting rod. The connecting rod has a pivot, one end of the connecting rod has a connecting part for connecting to the monitor, and the other end of the connecting rod has a tension spring, the other end of which is mounted on the vertical pole. The stand also includes:

[0008] The rotating ring has its inner wall rotatably connected to the rotating shaft and its outer wall rotatably connected to the upright;

[0009] A limiting component, used to limit the rotation angle between the rotating shaft and the rotating ring;

[0010] The locking mechanism has a first stroke that locks the relative position of the rotating ring and the upright, and a second stroke that locks the relative position between the rotating ring and the shaft.

[0011] The aforementioned computer monitor bracket includes a limiting component comprising a limiting groove constructed inside a rotating ring and a protrusion constructed on the outer wall of a rotating shaft, the protrusion being located within the limiting groove.

[0012] The aforementioned computer monitor bracket includes a locking mechanism comprising an adjusting screw rotatably connected to the outer wall of the upright, a pressing block threaded onto the adjusting screw, and a friction pad embedded on the side of the pressing block near the upright. When the adjusting screw rotates, the pressing block can move against the outer wall of the upright, the end of the rotating shaft, or the end of the rotating ring.

[0013] In the aforementioned computer monitor bracket, a movable block is slidably mounted on the upright. A support rod is hinged to one side of the movable block, and the other end of the support rod is hinged to the side of the connecting rod near the connecting part. One end of a tension spring is hinged to the movable block, and the other end is hinged to the side of the connecting rod away from the connecting part.

[0014] In the aforementioned computer monitor stand, the support rod is configured as a telescopic rod.

[0015] The aforementioned computer monitor bracket includes a support rod that is hinged to a movable block and a lead screw that is hinged to a connecting rod. The sleeve rod has a movable cavity, and an adjusting ring is rotatably connected to the end of the movable cavity away from the movable block. The adjusting ring is threadedly connected to the lead screw.

[0016] In the aforementioned computer monitor stand, the upright has a movable groove, and a movable block is slidably disposed within the movable groove.

[0017] In the aforementioned computer monitor bracket, a first slider and a second slider are slidably disposed on the connecting rod. The first slider is located on the side of the upright rod away from the connecting part, and the second slider is located on the side of the upright rod close to the connecting part. A tension spring is hinged to the bottom of the first slider, and a support rod is hinged to the bottom of the second slider.

[0018] In the aforementioned computer monitor stand, when the monitor is mounted on the connecting part, the first slider tends to rise and the second slider tends to fall, thereby forcing the tension spring to stretch and increasing the elastic force of the tension spring to balance the weight of the monitor.

[0019] In the aforementioned computer monitor bracket, the bottom of the connecting rod is provided with a sliding groove along its length, and both the first slider and the second slider are slidably connected within the sliding groove.

[0020] In the above technical solution, the computer monitor bracket provided by the present invention can lock the relative position of the rotating ring and the upright through the first stroke of the locking mechanism after the monitor is fixed to the connecting part. Then, the elastic force of the tension spring can be adjusted according to the situation. During the process, if the rotating shaft deflects in the limiting component, it means that the elastic force of the tension spring and the weight of the monitor have reached the edge of equilibrium. At this time, the second stroke of the locking mechanism can be run to lock the relative position of the rotating shaft and the rotating ring, so as to avoid the situation where the torque at the hinge of the upright and the connecting rod is not eliminated and the locking occurs directly.

Detailed Implementation

[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] Reference Figure 1-7This invention provides a computer monitor stand, including a stand 1 and a connecting rod 2. The connecting rod 2 is provided with a rotating shaft 14. One end of the connecting rod 2 is provided with a connecting part 3 for connecting to the monitor, and the other end of the connecting rod 2 is provided with a tension spring 5. The other end of the tension spring 5 is provided on the stand 1. The stand also includes a rotating ring 101, a limiting component, and a locking mechanism. The inner wall of the rotating ring 101 is rotatably connected to the rotating shaft 14, and the outer wall is rotatably connected to the stand 1. The limiting component is used to limit the rotation angle between the rotating shaft 14 and the rotating ring 101. The locking mechanism has a first stroke for locking the relative position between the rotating ring 101 and the stand 1 and a second stroke for locking the relative position between the rotating ring 101 and the rotating shaft 14.

[0033] Specifically, the bottom of the upright 1 is vertically fixed to the desktop by a clamping plate or other mounting structure. The connecting rod 2 and the upright 1 are hinged to each other to form a "T"-shaped structure. The connecting part 3 is located at one end of the connecting rod 2, and the connecting part 3 is provided with bolts or other fixing structures to connect the monitor. One end of the tension spring 5 is located on the side of the connecting rod 2 away from the connecting part 3, and the other end is located on the upright 1. In this way, the elastic force of the tension spring 5 can be used to balance the weight of the monitor. The end of the tension spring 5 can be slidably set on the connecting rod 2 or the upright 1, thereby adjusting the length of the tension spring 5 to change the magnitude of the balancing force. All of the above are existing technologies and will not be described in detail here. The innovation of this invention lies in the following: a rotating ring 101, a limiting component, and a locking mechanism are provided on the upright 1. The limiting component can be a flange limiting structure from the prior art, which limits the relative rotation angle between the rotating shaft 14 and the rotating ring 101 to between 0 and 10 degrees. The locking mechanism can be two sets of compression locking structures from the prior art. After the display is fixed to the connecting part 3, the first stroke of the locking mechanism can lock the relative position of the rotating ring 101 and the upright 1, thus facilitating the user's operation of the tension spring 5 and other structures. After the display is fixed, if the weight of the display is large, the connecting part 3 will tend to descend, and the rotating shaft 14 will deflect to... Conversely, if the tension of spring 5 is large, the rotating shaft 14 will deflect to the other end of the limiting component. Then, the tension of spring 5 can be adjusted as needed (such as adjusting the position of the end of spring 5 on the connecting rod 2 or the upright 1). During the process, if the rotating shaft 14 deflects in the limiting component, it means that the tension of spring 5 and the weight of the display have reached the edge of equilibrium, that is, the torque at the hinge of the upright 1 and the connecting rod 2 has been basically eliminated. At this time, the second stroke of the locking mechanism can be run to lock the relative position of the rotating shaft 14 and the rotating ring 101, so as to avoid the situation where the torque at the hinge of the upright 1 and the connecting rod 2 is not eliminated and the locking occurs directly.

[0034] In another embodiment of the present invention, the limiting component further includes a limiting groove constructed inside the rotating ring 101 and a protrusion 141 constructed on the outer wall of the rotating shaft 14, the protrusion 141 being located within the limiting groove. Specifically, when the locking mechanism is not in operation, the connecting rod 2 can rotate freely on the upright 1 via the rotating shaft 14 and the rotating ring 101. After the locking mechanism has completed its first stroke, the relative position of the rotating ring 101 and the upright 1 is locked. At this time, the connecting rod 2 can rotate at a certain angle within the limiting groove via the rotating shaft 14 and the protrusion 141. Furthermore, due to the influence of the display's gravity or the spring force of the tension spring 5, the protrusion 141 generally adheres to one end of the inner wall of the limiting groove. Figure 2 As shown, if the protrusion 141 is attached to the bottom wall of the limiting groove, it indicates that the weight of the display is relatively large. In this case, the tension of the tension spring 5 needs to be increased until the protrusion 141 moves away from the bottom wall of the limiting groove. At this point, the torque at the hinge of the connecting rod 2 and the upright rod 1 is basically eliminated. Then, the second stroke of the locking mechanism can be run to lock the relative position of the connecting rod 2 and the upright rod 1. Conversely, if the protrusion 141 is attached to the top wall of the limiting groove, it indicates that the tension of the tension spring 5 is relatively large. In this case, the tension of the tension spring 5 needs to be reduced until the protrusion 141 moves away from the top wall of the limiting groove. Then, the second stroke of the locking mechanism can be run.

[0035] Preferably, the locking mechanism includes an adjusting screw 15 rotatably connected to the outer wall of the upright 1. A pressing block 16 is threaded onto the adjusting screw 15. A friction pad is embedded on the side of the pressing block 16 closest to the upright 1. When the adjusting screw 15 rotates, the pressing block 16 can move against the outer wall of the upright 1, the end of the rotating shaft 14, or the end of the rotating ring 101. Specifically, a rubber friction pad is embedded on the side of the pressing block 16 closest to the upright 1. The adjusting screw 15 is positioned along the height of the upright 1. The adjusting screw 15 and the pressing block 16 are connected by a ball screw thread. When the pressing block 16 is at the bottom of its stroke, it is not disengaged from the rotating ring 101 and the rotating shaft 14, allowing the rotating ring 101 and the rotating shaft 14 to rotate freely. When the adjusting screw 15 moves the pressing block 16 upwards so that it fits against the end of the rotating ring 101, the pressing block 16 and the rotating ring 101 abut against each other. The relative positions of the rotating ring 101 and the upright 1 are locked by using friction. At this time, the pressing block 16 is not in contact with the rotating shaft 14, and the rotating shaft 14 can rotate in the limiting assembly (that is, the first stroke of the locking mechanism). After the adjusting screw 15 continues to drive the pressing block 16 to move upward, the outer wall of the upright 1, the end of the rotating ring 101 and the end of the rotating shaft 14 are all in contact with the pressing block 16. In this way, the relative positions of the upright 1, the rotating ring 101 and the rotating shaft 14 can be locked by using the friction of the pressing block 16 (that is, the second stroke of the locking mechanism).

[0036] In another embodiment of the present invention, a movable block 4 is slidably disposed on the upright 1, a support rod 6 is hinged to one side of the movable block 4, and the other end of the support rod 6 is hinged to the side of the connecting rod 2 near the connecting part 3. One end of the tension spring 5 is hinged to the movable block 4, and the other end is hinged to the side of the connecting rod 2 away from the connecting part 3. Specifically, when the monitor is not installed, the top of the tension spring 5 forces the connecting rod 2 to tilt, causing the connecting part 3 to move upward. The bottom of the tension spring 5 forces the movable block 4 to move upward, thereby forcing the connecting rod 2 to tilt and causing the connecting part 3 to move upward via the support rod 6. The advantage of this design is that after the connecting part 3 and the monitor are fixed, if the tension spring 5 is insufficient to balance the weight of the monitor, the weight of the monitor will tend to force the connecting part 3 to move downward. During this process, the connecting rod 2 rotates to force the movable block 4 to move downward via the support rod 6. This will stretch the bottom of the tension spring 5. When the connecting rod 2 rotates, the end away from the connecting part 3 can also directly stretch the top of the tension spring 5. This design can use the small rotation angle of the connecting rod 2 to force the tension spring 5 to perform a large stroke of stretch (compared to the tension spring 5 in the prior art). With one end set on the upright 1 and the other end set on the side of the connecting rod 2 away from the connecting part 3, if the top of the tension spring 5 can stretch by one unit after the connecting rod 2 rotates by 10 degrees, then in this embodiment, both the top and bottom ends of the tension spring 5 can stretch by one unit after the connecting rod 2 rotates by 10 degrees. Obviously, in this embodiment, the elastic force of the tension spring 5 can be rapidly increased to balance the weight of the display as soon as possible, thereby rapidly increasing the elastic force of the tension spring 5 to balance the weight of the display as soon as possible, and minimizing the torque at the hinge of the upright 1 and the connecting rod 2, so that the relative position of the upright 1 and the connecting rod 2 can be fixed with a smaller force later (if there is no elastic force balance from the tension spring 5, the connecting rod 2 will tend to rotate, and a larger frictional force will be required to fix the relative position of the upright 1 and the connecting rod 2 later).

[0037] Preferably, the support rod 6 is configured as a telescopic rod. Specifically, in the above embodiment, the length of the support rod 6 is fixed. When the weight of the display is different, the connecting rod 2 needs to be rotated to different angles to achieve balance. Obviously, this bracket cannot suspend the display at any height position according to the user's requirements. Therefore, the support rod 6 is configured as a telescopic rod. The telescopic rod can be a manual or electric telescopic structure, which is prior art and will not be described in detail. Preferably, the support rod 6 includes a sleeve rod 7 hinged to the movable block 4 and a lead screw 8 hinged to the connecting rod 2. The sleeve rod 7 has a movable cavity. An adjusting ring 9 is rotatably connected to the end of the movable cavity away from the movable block 4, and the adjusting ring 9 is threadedly connected to the lead screw 8. The movable cavity is set along the length direction of the sleeve rod 7. The lead screw 8 and the adjusting ring 9 are threadedly connected by a ball screw. When the adjusting ring 9 is rotated, the lead screw 8 will enter or move out of the movable cavity accordingly, thereby adjusting the length of the overall support rod 6.

[0038] With this setup, after installing the monitor, first adjust the monitor and connecting rod 2 to the required angle and position, then run the first stroke of the locking mechanism to lock the relative position of the rotating ring 101 and the upright rod 1. Subsequently, adjusting the length of the support rod 6 can change the elastic force of the tension spring 5 while maintaining the angle of the connecting rod 2. Figure 4 As shown (not illustrated on the display), if the protrusion 141 is attached to the bottom wall of the limiting groove in this state, the adjusting ring 9 is rotated to extend the support rod 6. If the protrusion 141 is attached to the top wall of the limiting groove in this state, the adjusting ring 9 is rotated to retract the support rod 6, thereby minimizing the torque between the upright rod 1 and the connecting rod 2 while maintaining the angle of the connecting rod 2.

[0039] In another embodiment of the present invention, preferably, the upright 1 is provided with a movable groove, and the movable block 4 is slidably disposed within the movable groove. Specifically, the upright 1 is generally U-shaped, that is, two clamping plate structures are formed on the upright 1, and the connecting rod 2 and the movable block 4 are both located between the two clamping plate structures. The movable groove is constructed on the clamping plate structures along the length direction of the upright 1, so that the movable block 4 can slide vertically on the upright 1. This arrangement allows the connecting rod 2, the movable block 4, the tension spring 5, and the support rod 6 to all move between the two clamping plate structures.

[0040] Furthermore, a first slider 10 and a second slider 11 are slidably disposed on the connecting rod 2. The first slider 10 is located on the side of the upright 1 away from the connecting part 3, and the second slider 11 is located on the side of the upright 1 closer to the connecting part 3. The tension spring 5 is hinged to the bottom of the first slider 10, and the support rod 6 is hinged to the bottom of the second slider 11. When the display is installed on the connecting part 3, the first slider 10 tends to rise, and the second slider 11 tends to fall, thereby forcing the tension spring 5 to stretch and increasing the elastic force of the tension spring 5 to balance the weight of the display. Specifically, in the above embodiment, the top ends of the tension spring 5 and the support rod 6 can be directly hinged to the connecting rod 2, which restricts the position of the top ends of the tension spring 5 and the support rod 6, making it impossible to adjust them according to the situation. Therefore, the first slider 10 and the second slider 11 are slidably disposed on the connecting rod 2 so that the tension spring 5 and the support rod 6 can be disposed on the sliding structure at the bottom of the connecting rod 2. In this embodiment, a linear drive structure can be provided on the connecting rod 2 to adjust the position of the first slider 10 and the second slider 11. The linear drive structure can be an electric push rod structure in the prior art, which will not be described in detail here. During the process of balancing the weight of the monitor using tension spring 5 and support rod 6, the lever arm is quite important. Without replacing tension spring 5, if the weight of the monitor is significant, the lever arm of tension spring 5 and support rod 6 can be appropriately increased. This means adjusting the first slider 10 and the second slider 11 closer to each other and further away from the support rod 1 (to achieve this). Figure 6For example, if the monitor's weight is relatively low, the lever arms of the tension spring 5 and the support rod 6 can be appropriately lowered, that is, the first slider 10 and the second slider 11 can be adjusted to be closer to the upright rod 1. In this way, the lever arms of the tension spring 5 and the support rod 6 can be adaptively adjusted according to the monitor's condition, thereby better utilizing the elastic force of the tension spring 5 to balance the monitor's weight.

[0041] As an alternative to the aforementioned linear drive mechanism, preferably, the bottom of the connecting rod 2 has a sliding groove along its length, and the first slider 10 and the second slider 11 are both slidably connected within the sliding groove. A bidirectional threaded rod 12 is rotatably connected within the sliding groove, and the first slider 10 and the second slider 11 are respectively threaded to both sides of the bidirectional threaded rod 12. Specifically, the sliding groove is provided along the length of the connecting rod 2, and the bottom of the sliding groove has an opening, allowing the bottoms of the first slider 10 and the second slider 11 to protrude from the bottom of the sliding groove, facilitating hinge connection with the tension spring 5 or the support rod 6; the bidirectional threaded rod 12 is rotatably connected to the connecting rod 2, and both sides of the bidirectional threaded rod 12 have threads, with opposite thread directions on both sides. The first slider 10 and the second slider 11 are both threaded to the bidirectional threaded rod 12 via a ball screw structure, so that when the bidirectional threaded rod 12 rotates, it can drive the first slider 10 and the second slider 11 to move closer or further apart, thereby synchronously adjusting the lever arm of the tension spring 5 and the support rod 6. It should be noted that in this embodiment, the bidirectional threaded rod 12 can be used in conjunction with the adjusting ring 9 to finely adjust the balance force between the tension spring 5 and the support rod 6, thereby eliminating the torque between the connecting rod 2 and the upright rod 1 as much as possible while allowing the display to hover at any height.

[0042] Preferably, when the support rod 6 is retracted to its limit, its length is less than the distance from the sliding groove to the movable groove. Specifically, in this embodiment, the bidirectional threaded rod 12 and the adjusting ring 9 work together to also house the connecting rod 2. The first slider 10 and the second slider 11 are adjusted to a position close to the upright rod 1 by the bidirectional threaded rod 12. Then, by retracting the support rod 6 by the adjusting ring 9, the connecting part 3 can be driven to descend. At the same time, the first slider 10 also moves to a position close to the upright rod 1 (similar to the deformation of a triangle, with the upright rod 1 being the hypotenuse of the triangle). The length of the tension spring 5 is also retracted as much as possible to avoid the tension spring 5 being in a stretched state for a long time. In this way, the connecting rod 2 can be as close as possible to one side of the upright rod 1, so that the device is in a housed state.

[0043] In another embodiment of the present invention, a brake block 17 is slidably connected to the rotating shaft 14 (a portion of the brake block 17 has a non-rotating part that passes through the rotating shaft 14, allowing the brake block 17 to extend from inside the sliding groove to outside the rotating shaft 14). The end of the brake block 17 near the bidirectional threaded rod 12 is arc-shaped and has a friction structure embedded therein (the friction structure can be a rubber pad from the prior art, not shown). A return spring 18 is also included, with both ends of the return spring 18 fixed to the brake block 17 and the inner wall of the sliding groove, respectively, so that the brake block 17 is forced away from the bidirectional threaded rod 12 by the return spring 18. The end of the brake block 17 away from the bidirectional threaded rod 12 extends to outside the rotating shaft 14. The ends of the brake block 17 and the pressing block 16 that are close to each other are both constructed with wedge-shaped surfaces. When the angle of the connecting rod 2 is adjusted, the pressing block 16 is at the bottom of its stroke. Figure 7 The left-hand squeezing block 16, and its corresponding brake block 17, do not abut against the bidirectional threaded rod 12. The connecting rod 2 can rotate freely on the upright 1 via the rotating shaft 14 and the rotating ring 101. After the display is installed, the squeezing block 16 is moved upward by adjusting the screw 15 to lock the relative position of the upright 1 and the rotating ring 101. Then, the elastic force of the tension spring 5 and the supporting force of the support rod 6 are adjusted until the protrusion 141 deflects in the limiting groove. Then, the squeezing block 16 is moved upward by adjusting the screw 15 to lock the relative position of the rotating ring 101 and the rotating shaft 14. Then, the squeezing block 16 is moved upward by adjusting the screw 15 to lock the relative position of the rotating ring 101 and the rotating shaft 14. 5 drives the pressing block 16 to move upward. During the upward movement of the pressing block 16, it will abut against the brake block 17 through the wedge-shaped surface, so as to force the brake block 17 to overcome the elastic force of the return spring 18 and abut against the bidirectional threaded rod 12 (after the connecting rod 2 rotates, the wedge-shaped surfaces on the pressing block 16 and the brake block 17 are not facing each other, but this does not affect the fact that when they press against each other, the brake block 17 is forced to approach the bidirectional threaded rod 12. Preferably, the top of the pressing block 16 can be constructed as an arc-shaped pressing surface to adapt to the pressing of the wedge-shaped surface of the brake block 17). When the brake block 17 abuts against the bidirectional threaded rod 12, the pressing block 16 also simultaneously abuts against the end of the rotating ring 101, the end of the rotating shaft 14 and the brake block 17. Figure 7 The right-hand squeezing block 16 can be used to lock the relative position of the upright 1 and the connecting rod 2 by using the friction of the squeezing block 16, while restricting the bidirectional lead screw 8. When it is necessary to adjust the angle of the connecting rod 2, the adjusting screw 15 can be rotated again to separate the squeezing block 16 and the rotating shaft 14, thereby releasing the locking and restriction at the same time.

[0044] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
