[0019] To facilitate understanding of this utility model, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as "connected" to another element, it can be directly on the other element, or one or more intermediate elements can exist between them.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0021] In related technologies, most monitor stands are manually adjustable. Users need to directly push, pull, and rotate the monitor by hand to adjust its position and orientation, such as adjusting the tilt or yaw angle. The adjustment process relies entirely on human power, which is quite strenuous for larger and heavier monitors, and the adjustment feel is not ideal. Manual adjustment makes it difficult to achieve precise control, and users often need to make repeated fine adjustments to achieve the ideal position, making the operation cumbersome.

[0022] To resolve the aforementioned technical issues, please refer to the following: Figures 1 to 3 This application provides a monitor bracket 100, including a mounting structure 10, a pitch joint 20, and a yaw joint 30.

[0023] Mounting structure 10 is used to mount a display. Pitch joint 20 is connected to mounting structure 10 and is used to electrically drive mounting structure 10 to rotate relative to pitch joint 20 about a first axis O1. Yaw joint 30 is connected to pitch joint 20 and is used to electrically drive yaw joint 30 to rotate relative to yaw joint 20 about a second axis O2.

[0024] The structural principle of the monitor bracket 100 in this embodiment is as follows: it adopts two interconnected joints, both of which are electrically driven. The pitch joint 20 is directly connected to the mounting structure 10. Through electric drive, the monitor can be adjusted up and down around a first horizontal axis O1. The yaw joint 30 is connected to the pitch joint 20. Through electric drive, the entire pitch joint 20, the mounting structure 10, and the monitor can be adjusted left and right around a second vertical axis O2.

[0025] Understandably, the monitor stand 100 in this application embodiment changes the way users interact with the monitor stand 100, transforming laborious and imprecise manual adjustment into easy and precise electric drive. Users can easily adjust the monitor to the ideal tilt and yaw angles through buttons or software, improving the convenience and comfort of use.

[0026] In some embodiments, the display bracket 100 further includes a rotary joint 40, which connects the pitch joint 20 and the mounting structure 10. That is, the pitch joint 20 and the mounting structure 10 can be connected via the rotary joint 40. The rotary joint 40 can rotate relative to the pitch joint 20 about a first axis O1 under the drive of the pitch joint 20. The rotary joint 40 is also used to electrically drive the mounting structure 10 to rotate relative to the rotary joint 40 about a third axis O3. The third axis O3 is perpendicular to both the first axis O1 and the second axis O2.

[0027] Understandably, this embodiment further includes an electrically driven rotary joint 40. This rotary joint 40 is positioned between the pitch joint 20 and the mounting structure 10, and its function is to electrically drive the mounting structure 10 to rotate about a third axis O3, which is perpendicular to the aforementioned pitch and yaw axes. These three mutually perpendicular axes of motion together achieve complete three-degree-of-freedom electric adjustment of the display.

[0028] The pitch joint 20, yaw joint 30, and rotation joint 40 in this embodiment are several joint components located at the head of the monitor bracket 100. The monitor bracket 100 also includes a base, support arm, and other joint components. Other parts of the monitor bracket 100 can be set according to actual needs, and no restrictions are imposed here.

[0029] Please refer to the following: Figure 3and Figure 4 In some embodiments, the display bracket 100 further includes a torque compensation mechanism 50, which is disposed on the first axis O1. The torque compensation mechanism 50 is used to provide compensation torque for the rotation of the mounting structure 10 about the first axis O1 to counteract the torque generated by the weight of the display.

[0030] Understandably, the weight of the monitor continuously exerts a downward torque on the tilt joint 20, placing a significant static and dynamic load on its drive motor. The monitor bracket 100 in this embodiment incorporates a torque compensation mechanism 50, which actively provides a compensation torque opposite in direction to the downward tilt torque generated by the monitor's own weight, significantly reducing the performance requirements on the drive motor of the tilt joint 20. Because the gravitational load is compensated, the motor no longer needs to continuously consume a large amount of energy to maintain the monitor's angle, and the torque that needs to be overcome during tilt adjustment is also greatly reduced. Therefore, a lower-power, lower-cost, and more compact motor can be selected, thereby reducing the overall manufacturing cost, energy consumption, and operating noise of the product, while improving the system's reliability and lifespan.

[0031] Specifically, the pitch joint 20 includes a pitch base 21 and a pitch drive shaft 22. The pitch base 21 is connected to the yaw joint 30. The pitch drive shaft 22 is connected to both the pitch base 21 and the rotary joint 40. The pitch drive shaft 22 is coaxially arranged with the first axis O1 and can rotate relative to the pitch base 21.

[0032] The torque compensation mechanism 50 includes a torsion spring 51, which is sleeved on the pitch drive shaft 22. One end of the torsion spring 51 is fixed relative to the pitch base 21, and the other end of the torsion spring 51 is connected to the rotary joint 40.

[0033] Understandably, the pitch joint 20 includes a pitch base 21 and a pitch drive shaft 22, while the torque compensation mechanism 50 uses a torsion spring 51. One end of the torsion spring 51 is fixed to the relatively stationary pitch base 21, and the other end is connected to a component of the rotary joint 40 that rotates with the display. When the display tilts down, the torsion spring 51 is twisted and stores elastic energy, generating an upward resisting torque; when the display is raised, the torsion spring 51 releases energy to assist the motor.

[0034] In this embodiment, the torsion spring 51 and the pitch drive shaft 22 are coaxially arranged, which significantly improves the integration of the pitch joint 20, resulting in a compact structure, high space utilization, and direct and efficient transmission.

[0035] In other embodiments, the torque compensation mechanism 50 may also employ a gas spring, a constant force spring, or a counterweight to compensate for the torque generated by the weight of the display.

[0036] Please refer to the following: Figure 2 and Figure 3 In some embodiments, the pitch joint 20 further includes a pitch motor 23 and a reducer 24. The reducer 24 is connected to the pitch motor 23 and the pitch drive shaft 22 respectively. The reducer 24 is disposed on the pitch base 21, and the pitch motor 23 is located at the middle position in the width direction of the pitch joint 20.

[0037] The yaw joint 30 includes a yaw motor 31, the output shaft of which is coaxial with the second axis O2, and the output shaft of the pitch motor 23 is arranged parallel to the output shaft of the yaw motor 31.

[0038] Understandably, the pitch motor 23 of the pitch joint 20 is used in conjunction with the reducer 24, and the pitch motor 23 is positioned at the center of the pitch joint 20 in the width direction. Meanwhile, the output shaft of the yaw motor 31 of the yaw joint 30 coincides with the axis of the yaw motion, and the output shafts of the pitch motor 23 and the yaw motor 31 are arranged parallel to each other.

[0039] In this embodiment, the output shaft of the pitch motor 23 drives the pitch drive shaft 22 to rotate in the direction perpendicular to the output shaft via the reducer 24, so that the pitch motor 23 and the yaw motor 31 are arranged parallel to each other, which helps to optimize the head volume of the display bracket 100. At the same time, placing the pitch motor 23 in the center helps to improve the weight distribution of the entire movable joint, making it more stable during movement, reducing unnecessary vibration and inertia effects, and improving the stability and accuracy of motion control.

[0040] In some embodiments, the pitch base 21 includes two clamping plates 211, and the reducer 24 is provided with clamping plates 211 at both ends in the length direction. The reducer 24 is fixed on one of the clamping plates 211. The clamping plate 211 has an opening to avoid the pitch drive shaft 22, and the pitch motor 23 is located below the reducer 24.

[0041] The yaw joint 30 includes a fixed column 33 and a yaw head 32, and a yaw motor 31 is mounted on the fixed column 33. The yaw motor 31 is connected to the yaw head 32 and can drive the yaw head 32 to swing on the second axis O2. The yaw head 32 is connected to the clamping plate 211 so that when the yaw head 32 rotates, it drives the reducer 24 to rotate around the second axis O2.

[0042] The rotary joint 40 includes a mounting plate 41, a mating plate 42, and a rotary motor 43. A corresponding mating plate 42 is fixedly connected to each of the two opposite edges of the mounting plate 41. The mounting plate 41 is connected to the mounting structure 10. At least one of the opposite edges of the mounting plate 41 is connected to a corresponding mating plate 42. The mounting plate 41 is connected to both the mounting structure 10 and the rotary motor 43, which are located on opposite sides of the mounting plate 41. For example, the rotary motor 43 is located between the two mating plates 42. The two mating plates 42 can be arranged on the left and right sides of the rotary motor 43, or on the top and bottom sides of the rotary motor 43; no limitation is made here.

[0043] Specifically, the rotary motor 43 is fixed to the mounting plate 41 and located on one side of the mounting plate 41. The mounting plate 41 has an opening to avoid the output shaft of the rotary motor 43. The mounting structure 10 is located on the other side of the mounting plate 41 and connected to the rotary motor 43. The rotary motor 43 drives the mounting structure 10 to rotate on the first axis O1. Each end of the pitch drive shaft 22 is connected to a corresponding mating plate 42 and can rotate on the first axis O1 by driving the mating plate 42. Exemplarily, the rotary joint 40 also includes a reinforcing plate 44. A corresponding reinforcing plate 44 is stacked and connected to the inner side of each mating plate 42. The mating plate 42 and the reinforcing plate 44 are connected together to the pitch drive shaft 22. Specifically, each end of the pitch drive shaft 22 is provided with a key structure. Both the mating plate 42 and the reinforcing plate 44 are provided with keyways that match the key structure, so as to realize that the pitch drive shaft 22 drives the mating plate 42 to rotate.

[0044] In other embodiments, the support structures for the pitch joint 20 and the rotation joint 40 are not limited to multiple plate structures, and no limitation is made here.

[0045] In some embodiments, the torque limiting mechanism further includes a torsion spring rod 52, which is installed between two opposing plates 42, and the other end of the torsion spring 51 abuts against the torsion spring rod 52 from below.

[0046] Please review Figure 1 In some embodiments, the display bracket 100 further includes a limit detection element 60 and a control element (not shown in the figures). At least one of the mounting structure 10, the rotary joint 40, and the pitch joint 20 is provided with a corresponding limit detection element 60 at a preset position in the rotation stroke, and the corresponding limit detection element 60 is triggered when the rotation reaches the preset position of the rotation stroke.

[0047] The pitch joint 20, yaw joint 30, and rotatable joint 40 are electrically connected to and controlled by the control element. The control element is electrically connected to each limit detection element 60. The control element is used to stop at least one of the corresponding limit detection elements 60 in the mounting structure 10, rotatable joint 40, and pitch joint 20 from rotating.

[0048] Understandably, corresponding limit detection elements 60 are installed at preset limit positions of the rotational stroke of each joint, and the limit detection elements 60 are electrically connected to the control element. When any joint moves to its set end point and triggers the corresponding detection element, the control element will immediately cut off the power to the joint motor, causing it to stop rotating. Through the above-described configuration, this embodiment effectively prevents joints from over-rotating due to control errors or continuous user operation, thereby avoiding problems such as broken internal cables, interference with mechanical structures, or damage caused by excessive rotation.

[0049] For example, the limit detection element 60 can be a contact detection element, such as a microswitch. The limit detection element 60 can also be a non-contact detection element, such as a Hall effect sensor. Designers can select and specifically configure the limit detection element 60 according to actual needs; no restrictions are imposed here. For example, the rotation range of the rotary joint 40 and the yaw joint 30 is set to ±90°, and the rotation range of the pitch joint 20 is set to ±30°. For example, the control element can be a controller, a microprocessor, or a field-programmable gate array, or it can be an integrated circuit designed by the designer according to actual needs.

[0050] Please review Figure 3 In some embodiments, the display bracket 100 further includes a collision detection element 70, which is disposed on the mounting structure 10 and is used to detect external forces acting on the display.

[0051] The control element is electrically connected to the collision detection element 70. The control element is also used to stop the pitch joint 20, yaw joint 30 and rotatable joint 40 from rotating when the display is subjected to an external force, based on the detection result of the collision detection element 70.

[0052] For example, the collision detection element 70 can be a strain gauge, piezoelectric sensor, etc. When a strain gauge is used, it is disposed between the mounting structure 10 and the mounting plate 41. Designers can select and configure the collision detection element 70 according to actual needs, and there are no restrictions here.

[0053] Understandably, this embodiment of the application uses a collision detection element 70 on the mounting structure 10 to monitor in real time whether the display is subjected to external forces. The collision detection element 70 is connected to the control element. Once an external force is detected, such as the display encountering an obstacle like a wall or tabletop object during movement, or the user's active adjustment intervention, the mounting structure 10 will deform. The collision detection element 70 senses the deformation of the mounting structure 10 and sends a signal to the control element in response. The control element will immediately issue a command based on the signal provided by the collision detection element 70, either stopping all moving joints from rotating, or moving the display a preset distance away from the external force, and then stopping all moving joints from rotating. Through the above-mentioned settings, this embodiment of the application achieves intelligent anti-collision and anti-pinch protection, which not only protects the bracket and the display itself from damage due to collisions, but also protects the personal safety of the user and other objects in the surrounding environment, avoiding the risk of squeezing and collision that may occur during electric adjustment.

[0054] Please refer to the following: Figure 2 and Figure 3 In some embodiments, the mounting structure 10 includes a mounting plate 11, a display bracket 12, and locking fasteners 13. The display bracket 12 may be a VESA (Video Electronics Standards Association) bracket. The mounting plate 11 is connected to the rotary joint 40. The display bracket 12 is detachably connected to the mounting plate 11 for mounting a display. The locking fasteners 13 are connected to both the mounting plate 11 and the display bracket 12 to lock the display bracket 12 onto the mounting plate 11.

[0055] Understandably, this application embodiment adopts a split design, including a fixing plate 11 fixed to the rotating joint 40 of the bracket, and a detachable monitor bracket 12 for mounting on the back of the monitor. The two are quickly connected and secured using fasteners 13. During installation, the user can first fix the lightweight monitor bracket 12 to the monitor with screws, and then hang the monitor bracket 12 with the monitor on the fixing plate 11 of the bracket and lock it in place with the fasteners 13. This simplifies the monitor installation and removal process and significantly improves the user experience.

[0056] Please refer to the following: Figure 5 and Figure 6In some embodiments, the fixing plate 11 includes a first panel unit 111 and a first ear piece 112 that are perpendicularly connected to each other. The first panel unit 111 is connected to the rotation joint 40 and has a laterally extending limiting portion 1111. The display bracket 12 includes a second panel unit 121 and a second ear piece 122. The second panel unit 121 has two opposing encircling portions 1211.

[0057] The first panel unit 111 is embedded between two circumferential portions 1211, the limiting portion 1111 abuts against the circumferential portion 1211 upwards, the second ear piece 122 overlaps above the first ear piece 112, and the locking fastener 13 is connected to the first ear piece 112 and the second ear piece 122 respectively to lock the second ear piece 122 onto the first ear piece 112.

[0058] Specifically, the limiting part 1111 is a protrusion extending laterally outward from the bottom of the first panel unit 111. The embracing part 1211 is a structure in which the second panel unit 121 protrudes outward and extends and bends in a direction perpendicular to itself, so as to form a groove into which the first panel unit 111 can be inserted.

[0059] Understandably, the fixing plate 11 is provided with a first panel unit 111 and a first lug 112 for locking, and its panel unit also has a limiting part 1111 for support. The monitor bracket 12 is provided with a circumferential part 1211 for holding the first panel unit 111 of the fixing plate 11, and a second lug 122 that cooperates with the first lug 112. During installation, the panel unit of the fixing plate 11 is embedded between the circumferential parts 1211 of the monitor bracket 12 and supported upward by the limiting part 1111. At this time, most of the weight of the monitor is borne by the bracket. Then, the two lugs are overlapped and locked by the locking fastener 13 to complete the final fixation.

[0060] Optionally, the locking device 13 can be a snap-fit, latch, or bolt. For example, the first ear piece 112 is provided with a threaded hole, and the second ear piece 122 is provided with a through hole that aligns with the threaded hole. The locking device 13 is a hand-tightening screw, which is sequentially inserted into the through hole and the threaded hole and engages with the threaded hole to tighten and fix the first ear piece 112 and the second ear piece 122 to each other.
