Description

Technical Field

[0001] This invention relates to a bracket for supporting a display device and adjusting the height of the display device as needed, and more particularly to a bracket for adjusting the height of a display device. Background Technology

[0002] As we all know, display devices are widely used in people's daily lives, such as computer monitors in offices, monitors used in surveillance, and flat-screen TVs used in homes.

[0003] In order to make the position of the display device adjustable, the display device is usually installed on an adjustment bracket, which is then fixed by an external object; therefore, when adjusting the position of the display device, the operator can adjust the adjustment bracket.

[0004] Currently, in the multi-angle adjustment bracket for LCD screens disclosed in Chinese patent application number 201821501866.0, although the multi-angle adjustment bracket for LCD screens can achieve stepless adjustment of the LCD screen within a limited height, the position of the LCD screen after each adjustment cannot be accurately controlled precisely because the LCD screen is stepless. In particular, when multiple multi-angle adjustment brackets for LCD screens are used together, it is difficult to control the height consistency of the LCD screens on each multi-angle adjustment bracket.

[0005] Therefore, there is an urgent need for a display device leveling bracket that can quickly maintain a high degree of consistency in display devices to overcome the above-mentioned defects. Summary of the Invention

[0006] The purpose of this invention is to provide a display device leveling bracket that can quickly maintain the high consistency of the display device.

[0007] To achieve the above objectives, the display device adjustment bracket of the present invention includes a base, an intermediate connecting component, a motion seat, a support body, and a positioning mechanism. The support body is assembled and connected to the motion seat. The proximal end of the intermediate connecting component is assembled and connected to the base, and the distal end of the intermediate connecting component is assembled and connected to the motion seat. The intermediate connecting component and the motion seat also form a linkage mechanism, allowing the motion seat to perform translational and rotational movements with the cooperation of the intermediate connecting component. The positioning mechanism includes a first positioning body fixed to the motion seat and a second positioning body fixed to the distal end of the intermediate connecting component. One of the first and second positioning bodies has a plurality of positioning slots arranged spaced apart around the rotation centerline of the motion seat and along the rotation direction of the motion seat. The other of the first and second positioning bodies has a positioning latch for engaging with the positioning slots. During the translational and rotational movement of the motion seat together with the first positioning body, the positioning latch engages with different positioning slots to maintain the corresponding adjustment position of the motion seat.

[0008] Preferably, the first stop body has a clearance notch on the side facing away from the motion seat. This clearance notch provides a limiting step on the side of the first stop body facing away from the motion seat. The first stop body also extends into the second stop body through the clearance notch. The second stop body also covers the first stop body from the direction of the rotation center line of the motion seat. The limiting step prevents the motion seat and the first stop body from continuing to translate and rotate when it abuts against the second stop body.

[0009] Preferably, the gear slot is arranged facing the gear buckle from the direction of the rotation center line of the motion seat. The second gear body has a mounting hole extending through it along the rotation center line of the motion seat. The gear buckle is fitted into the mounting hole. A blocking structure is also provided in the mounting hole to block the mounting hole. A spring is provided between the blocking structure and the gear buckle. The spring always has the tendency to drive the gear buckle to protrude out of the second gear body. When the first gear body moves and rotates with the motion seat, it forces the gear buckle to retract inward so that it can move relative to the second gear body.

[0010] Preferably, the first stop body has an assembly hole that penetrates through the first stop body and faces the clearance notch.

[0011] Preferably, the intermediate connecting assembly includes a hinge seat mounted on the base, a first link hinged to the hinge seat at its proximal end, and a second link hinged to the hinge seat at its proximal end. The motion seat is hinged to the distal ends of both the first link and the second link. The motion seat, the first link, the second link, and the hinge seat together constitute a four-bar linkage. The second stop body is fixed to the distal end of the first link. The center line of the hinge structure between the first link and the motion seat forms the rotation center line of the motion seat.

[0012] Preferably, the second gear body is fixedly connected to the motion seat via a hinge structure between the distal end of the first link and the distal end of the first link.

[0013] Preferably, the display device gear adjustment bracket of the present invention further includes an auxiliary rod sandwiched between the second gear body and the first connecting rod from the direction of the rotation center line of the motion seat. The proximal end of the auxiliary rod, the proximal end of the first connecting rod, and the hinge seat are coaxially hinged, and the distal end of the auxiliary rod, the distal end of the first connecting rod, and the motion seat are coaxially hinged.

[0014] Preferably, the second stop body consists of two parts that clamp the distal end of the auxiliary rod along the rotation center line of the motion seat. Each second stop body has a through hole aligned along the rotation center line of the motion seat. A fastener is inserted into the through hole of each second stop body and locks all the second stop bodies together.

[0015] Preferably, the first link and the second link are parallel to each other, and the lengths of the first link and the second link are equal, so that the four-bar linkage forms a parallel four-bar linkage.

[0016] Preferably, the carrier is a plurality of carriers arranged at intervals along the rotation center line of the motion seat, each carrier corresponding to one motion seat, one stop mechanism and one intermediate connecting component, and one carrier is assembled on one corresponding motion seat.

[0017] Compared with the prior art, the display device adjustment bracket of the present invention further includes a stop mechanism, which comprises a first stop body fixed to the motion base and a second stop body fixed to the distal end of the intermediate connecting component. One of the first and second stop bodies has a plurality of stop slots arranged at intervals around the rotation center line of the motion base and along the rotation direction of the motion base. The other of the first and second stop bodies has a stop buckle for engaging with the stop slots. Therefore, during the process of the motion base translating and rotating relative to the base with the help of the intermediate connecting component, the translation and rotation of the motion base allows the stop buckle to selectively and automatically engage with different stop slots. By engaging the stop buckle with the stop slot, the motion base maintains the corresponding adjustment position, avoiding stepless adjustment. This ensures the accuracy of the adjustment position of the display device within a limited height and can quickly maintain the consistency of the display device height when multiple carriers are used together.

[0028] To illustrate the technical content and structural features of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0029] Please see Figure 1 The display device position adjustment bracket 100 of the present invention is applied to a display device so that the display device can be mounted on the display device position adjustment bracket 100 of the present invention, thereby facilitating the operator to adjust the position of the display device by adjusting the display device position adjustment bracket 100 of the present invention. Since the display device is not an invention of this application and is well known in the art, it will not be described in detail here.

[0030] Combined Figures 2 to 5 ,as well as Figure 8 The display device adjustment bracket 100 of the present invention includes a base 10, an intermediate connecting assembly 20, a motion seat 30, a support body 40, and a stop mechanism 50. The support body 40 is assembled and connected to the motion seat 30 so that the support body 40 moves together with the motion seat 30, thereby causing the display device mounted on the support body 40 to also move together with the motion seat 30. Preferably, in… Figures 1 to 5 In this configuration, the carrier 40 is rotatably mounted on the motion base 30 around a vertical axis structure 41, allowing the carrier 40 to rotate relative to the motion base 30 with the vertical axis structure 41 as the center of rotation. This better meets the need for the carrier 40 and the display device on it to perform more directional adjustments. Of course, depending on actual needs, the carrier 40 and the motion base 30 can also be fixed together (i.e., they cannot move relative to each other). Figure 1 The above is the limit.

[0031] Meanwhile, the proximal end of the intermediate connecting component 20 is assembled and connected to the base 10, with the base 10 providing support for the intermediate connecting component 20, resulting in the distal end of the intermediate connecting component 20 being suspended in mid-air, as shown in the figure. Figure 1 As shown, it is preferable that, in Figure 1 In this structure, the base 10 is a lever arm structure, and it is also rotatably assembled with an external object, allowing the base 10 to rotate relative to the external object. Of course, depending on actual needs, the base 10 and the external object can also be fixed together; therefore, it is not considered... Figure 1As shown, the distal end of the intermediate connecting component 20 is assembled and connected to the motion seat 30, providing support for the motion seat 30 and allowing the motion seat 30 and the distal end of the intermediate connecting component 20 to be suspended in the air. The intermediate connecting component 20 and the motion seat 30 also form a linkage mechanism, enabling the motion seat 30 to perform translational and rotational movements with the cooperation of the intermediate connecting component 20. Preferably, the linkage mechanism is a four-bar linkage as described below, and most preferably a parallel four-bar linkage, so that the four-bar linkage has only one degree of freedom, thus ensuring that the trajectory of the motion seat 30 in translational and rotational movements with the cooperation of the intermediate connecting component 20 remains unchanged. Of course, other linkage mechanisms can be used as needed, but this is not a limitation.

[0032] Furthermore, the stop mechanism 50 includes a first stop body 51 fixed to the motion seat 30 and a second stop body 52 fixed to the distal end of the intermediate connecting assembly 20. The first stop body 51 has three openings centered on the rotation center line 31 of the motion seat 30 and along the rotation direction of the motion seat 20 (see...). Figure 5 The gear slots 511 are arranged in a clockwise and counterclockwise direction to meet the needs of three-speed adjustment. Of course, depending on actual needs, the number of gear slots 511 can also be two, four, five or six to correspondingly meet the needs of two-speed, four-speed, five-speed or six-speed adjustment. Figure 5 The following is a limited description; the second gear body 52 is provided with a gear buckle 53 for engaging with the gear slot 511. The gear buckle 53 engages with different gear slots 511 during the translation and rotation of the moving seat 30 together with the first gear body 51, as shown in the diagram. Figure 8 or Figure 10 As shown, this ensures that the motion seat 30 maintains the corresponding adjustment position, effectively preventing stepless adjustment of the motion seat 30 and thus ensuring the accuracy of the position adjustment of the motion seat 30. It should be noted that, according to actual needs, the positions of the stop slot 511 and the stop latch 53 can be interchanged. That is, the stop latch 53 is provided by the first stop body 51, and the stop slot 511 is opened by the second stop body 52. ​​This still achieves the purpose of the motion seat 30 selectively engaging the stop latch 53 with different stop slots 511 during translation and rotation. It should be further noted that the stop slot 511 here can refer to a groove-shaped structure or a hole-shaped structure. More specifically, as follows:

[0033] like Figure 3 , Figure 4 and Figure 5As shown, the intermediate connecting assembly 20 includes a hinge seat 21 mounted on the base 10, a first link 22 with its proximal end hinged to the hinge seat 21, and a second link 23 with its proximal end hinged to the hinge seat 21. The motion seat 30 is hinged to the distal ends of both the first link 22 and the second link 23. The motion seat 21, the first link 22, the second link 23, and the hinge seat 21 together constitute a four-bar linkage, so that the four-bar linkage has only one degree of freedom, thereby making the trajectory of the motion seat 30's translational and rotational movements fixed, thus making the control of the motion seat 30 easier; the second gear body 52 is fixed to the distal end of the first connecting rod 22, and the distal end of the first connecting rod 22 provides support for the second stop body 52. ​​The center line of the hinge structure 24 of the first connecting rod 22 and the motion seat 30 forms the rotation center line 31 of the motion seat 30. Preferably, the second stop body 52 is fixedly connected to the hinge structure 24 of the motion seat 30 and the distal end of the first connecting rod 22 through the distal end of the first connecting rod 22. This design makes the first connecting rod 22, the motion seat 30 and the second stop body 52 coaxially hinged, thereby making their assembly more compact and reasonable, and simplifying the assembly process. Specifically, in Figure 5 In this configuration, the proximal end of the first link 22 is hinged to the hinge seat 21 to form a first hinge center line P1; the proximal end of the second link 23 is hinged to the hinge seat 21 to form a second hinge center line P2; and the distal end of the second link 23 is hinged to the motion seat 30 to form a third hinge center line P3. The hinge center line formed by the distal end of the first link 22 and the motion seat 30 is the rotation center line 31 of the motion seat 30. Preferably, the first link 22 and the second link 23 are parallel to each other, and the first link 22... The lengths of 22 and 23 are equal, so that the four-bar linkage forms a parallel four-bar linkage. That is, the distance between the first hinge center line P1 and the rotation center line 31, and the distance between the second hinge center line P2 and the third hinge center line P3 are equal. Similarly, the distance between the first hinge center line P1 and the second hinge center line P2, and the distance between the rotation center line 31 and the third hinge center line P3 are equal. This design makes the translational and rotational movements of the motion seat 30 smoother and more reliable. More specifically, in Figure 5 In this case, the distance between the first hinge center line P1 and the second hinge center line P2 is less than the distance between the first hinge center line P1 and the rotation center line 31, but not less than... Figure 5 The above is the limit.

[0034] Among them, Figures 2 to 4 In order to effectively increase the load-bearing capacity, the display device adjustment bracket 100 of the present invention also includes a direction from the rotation center line 31 of the motion seat 30 (see...). Figure 2The auxiliary rod 60 (pointed to by the arrow in the first gear body 51 and in the opposite direction) is sandwiched between the second gear body 52 and the first connecting rod 22. The proximal end of the auxiliary rod 60, the proximal end of the first connecting rod 22, and the hinge seat 21 are coaxially hinged, meaning that the hinge center lines of the three are all indicated by the label P1, thus simplifying the assembly structure between the three. The distal end of the auxiliary rod 60, the distal end of the first connecting rod 22, and the motion seat 30 are coaxially hinged, meaning that the hinge center lines of the three are all indicated by the label 31, thus simplifying the assembly structure between the three and effectively preventing the introduction of the auxiliary rod 60 from affecting the movement of the parallel four-bar linkage. Specifically, in Figure 2 and Figure 3 In this configuration, two second stop bodies 52 clamp the distal end of the auxiliary rod 60 along the rotation center line 31 of the motion seat 30. Each second stop body 52 has a through hole 522 aligned along the rotation center line 31 of the motion seat 30. A fastener 56 passes through the through hole 522 of each second stop body 52 and locks all the second stop bodies 52 together. This design facilitates the assembly of two second stop bodies 52 onto the first connecting rod 22 and ensures the stable reliability of the second stop bodies 52. For example, in... Figure 2 and Figure 3 In this context, fastener 56 is a screw, but not limited to it. It should be noted that when the auxiliary rod 60 is introduced, the two second stop bodies 52 are locked together by the fastener 56, thereby causing the two second stop bodies 52 to hug the far end of the auxiliary rod 60. When the auxiliary rod 60 is removed, the two second stop bodies 52 can then be made to hug the far end of the first connecting rod 22.

[0035] like Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 9 As shown, the first gear shift body 51 has a clearance notch 512 on the side facing away from the motion seat 30. The clearance notch 512 gives the side of the first gear shift body 51 facing away from the motion seat 30 a limiting step 513. The first gear shift body 51 also extends into the second gear shift body 52 by means of the clearance notch 512, as shown in the figure. Figure 6 and Figure 9 As shown, the second stop body 52 provides auxiliary guidance to the first stop body 51, thereby ensuring smooth relative movement between the two; the second stop body 52 also covers the first stop body 51 from the direction of the rotation center line 31 of the motion seat 30; therefore, the limiting step 513 prevents the motion seat 30 and the first stop body 51 from continuing to translate and rotate when it abuts against the second stop body 52, for example in Figure 9 In this state, the limiting step 513 prevents the motion seat 30 and the first stop body 51 from continuing to translate and rotate clockwise, thereby effectively preventing the motion seat 30 from being over-adjusted. It should be noted that, in conjunction with... Figure 5 and Figure 10 When the limiting step 513 abuts against the second stop body 52, the limiting buckle 53 is still engaged with... Figure 5 The stop slot 511 in the lower left corner is engaged to keep the motion seat 30 in the adjusted position.

[0036] like Figure 3 , Figure 8 and Figure 10As shown, the gear slot 511 is arranged facing the gear buckle 53 from the direction of the rotation center line 31 of the motion seat 30. This design avoids increasing the thickness of the second gear body 52 along the direction of the first gear body 51 facing away from the motion seat 30. The second gear body 52 has a through mounting hole 521 along the rotation center line 31 of the motion seat 30. The gear buckle 53 is assembled into the mounting hole 521. A blocking structure 54 is also provided in the mounting hole 521 to block the mounting hole 521. A spring 56 is provided between the blocking structure 54 and the gear buckle 53. The spring 56 always has the function of driving the gear buckle 53 to protrude from the second gear body 511. The trend of 2 is to enable the shift latch 53 to have a telescopic function with the help of spring 56, so that the shift latch 53 and the first shift body 51 are kept in abutting state; when the first shift body 51 moves and rotates with the moving seat 30, it forces the shift latch 53 to retract and move relative to the second shift body 52, so that when the shift latch 53 is aligned with the shift slot 511, the shift latch 53 automatically engages in the aligned shift slot 511 under the action of spring 56, so as to achieve the purpose of automatic engagement; wherein, with the cooperation of mounting hole 521 and plugging structure 54, the assembly operation of shift latch 53 at the second shift body 52 is convenient. Specifically, the plugging structure 54 is inserted into the mounting hole 521 by tightening. It can also be understood that the plugging structure 54 and the mounting hole 521 adopt an interference fit to simplify the assembly process. Of course, depending on actual needs, it can also be fixed to the second stop body 52 by gluing or welding. At the same time, the first stop body 51 has an assembly hole 514 that passes through the first stop body 51 and faces the clearance notch 512. This design makes it easy for the operator to fix the first stop body 51 to the motion seat 30 with a screw. That is, the screw is inserted into the assembly hole 514 from one side of the clearance notch 512 and then threaded to the motion seat 30, and the screw locks the first stop body 51 and the motion seat 30 together. It should be noted that, as described above, when there are two second gear positions 52, the first gear position 51 has a gear position slot 511 on one side facing each second gear position 52. Correspondingly, each second gear position 52 has a gear position latch 53. This design allows the gear position latch 53 to latch onto the gear position slot 511 on the first gear position 51 from two directions, thereby making the adjusted position of the adjustable motion seat 30 more stable. In addition, the gear position latch 53 and the second gear position 52 can be made into an integral structure. For example, the gear position latch 53 can be a spring-loaded structure suspended at the second gear position 52.

[0037] The working process of the display device position adjustment bracket 100 of the present invention will be described with reference to the accompanying drawings. When the display device needs to be adjusted, the operator applies force to the display device mounted on the support 40, causing the display device to drive the moving seat 30 to perform translational and rotational movements in cooperation with the intermediate connecting component 20 through the support 40. The translational and rotational movement trajectory of the moving seat 30 is controlled by the linkage mechanism formed by the intermediate connecting component 20 and the moving seat 30. During the translational and rotational process of the moving seat 30, the first stop body 51 on the moving seat 30 and the second stop body 52 on the intermediate connecting component 20 move relative to each other, thereby causing the stop latch 53 to disengage from one stop slot 511 and then align with and engage with the other stop slot 511, thus achieving the purpose of adjusting the position of the moving seat 30. It is worth noting that during the gear adjustment process, the operator can apply force to the display device, the carrier 40, or the motion seat 30, and is not limited to the aforementioned description.

[0038] Compared with the prior art, the display device adjustment bracket 100 of the present invention further includes a stop mechanism 50. The stop mechanism 50 includes a first stop body 51 fixed to the motion seat 30 and a second stop body 52 fixed to the distal end of the intermediate connecting assembly 30. One of the first stop body 51 and the second stop body 52 is provided with a plurality of stop slots 511 arranged around the rotation center line 31 of the motion seat 30 and spaced apart along the rotation direction of the motion seat 30. The other of the first stop body 51 and the second stop body 52 is provided with a stop slot 511 for cooperating with the stop slots 511. The position latch 53; therefore, during the process of the motion seat 30 translating and rotating relative to the base 10 with the help of the intermediate connecting component 20, the translation and rotation of the motion seat 30 allows the position latch 53 to selectively and automatically engage with different position slots 511, so that the motion seat 30 can maintain the corresponding adjustment position by means of the engagement of the position latch 53 with the position slot 511, avoiding stepless adjustment, thereby ensuring the accuracy of the adjustment position of the display device within the limited height, and quickly maintaining the consistency of the display device height when multiple carriers 40 are used together.

[0039] It should be noted that although the attached drawings show one carrier 40 corresponding to one motion seat 30, one stop mechanism 50, and one intermediate connecting component 20, according to actual needs, multiple carriers 40 can be arranged spaced apart along the rotation center line 31 of the motion seat 20, with each carrier 40 corresponding to one motion seat 30, one stop mechanism 50, and one intermediate connecting component 20. In this case, one carrier 40 is mounted on its corresponding motion seat 30. At this time, the proximal ends of all intermediate connecting components 20 can be mounted on the same base 10, which will increase the volume of the base 10. Of course, additional bases 10 can also be added, ensuring that the number of bases 10 is the same as the number of intermediate connecting components 20, thereby ensuring that the proximal end of each intermediate connecting component 20 is mounted on a corresponding base 10. In this case, it can be understood that there are multiple stop adjustment brackets 100 for the display device of the present invention, and their number is the same as the number of carriers 40.

[0040] The above-disclosed examples are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are within the scope of the present invention.
