Detailed Implementation

[0024] The present invention will now be described in detail with reference to the accompanying drawings.

[0025] like Figure 1-6 As shown, a multi-height adjustable video conferencing set includes a TV frame 1, a support module that can be vertically adjusted for height, a TV module 65 mounted on the support module, and a lifting plate 47 with a connecting plate 31 mounted on the lifting plate 47.

[0026] The vertical position of the television can be adjusted by raising and lowering the support module using the lifting plate 47; this ensures that the center of the display screen is aligned with the participants' line of sight, reducing the burden on the cervical spine and improving comfort during long meetings.

[0027] The TV frame 1 includes a pair of parallel and spaced bottom support cylinders 11, with multiple first transverse reinforcing plates 13 arranged between the two bottom support cylinders 11. The bottom support cylinders 11 are formed with hollow holes 2, and top support columns 12 are inserted into the bottom support cylinders 11 through the hollow holes 2. Multiple second transverse reinforcing plates 14 are arranged between the two top support columns 12. The top of the top support column 12 is formed with a longitudinal connecting surface 15, which is connected to the lifting plate 47 through holes and screws.

[0028] In this embodiment, a pair of bottom support cylinders 11 and multi-level reinforcing plates form a stable I-shaped support structure. The hollow hole 2 of the bottom support cylinder 11 cooperates with the top support column 12 to realize the vertical lifting range and meet the needs of different meeting scenarios and user heights.

[0029] Furthermore, the TV frame 1 also includes a support plate 16 disposed between two bottom support cylinders 11 and two top support columns 12, the support plate 16 being sequentially connected to a plurality of first transverse reinforcing plates 13 and second reinforcing plates. One of the bottom support cylinders 11 is fitted with a rotatable adjusting screw sleeve 21 at its top, and the bottom end of the top support column 12 is formed with a bottom thread structure that threadedly engages with the adjusting screw sleeve 21.

[0030] The adjusting screw sleeve 21 has a T-shaped cross-section and is fitted with a flat bearing 22. The bottom surface of the flat bearing 22 contacts the top surface of the bottom support cylinder 11. Under the rolling support of the flat bearing 22, the friction of the adjusting screw sleeve 21 is reduced, making it easier to rotate. Thus, the height of the top support column 12 can be adjusted by rotating the adjusting screw sleeve 21, thereby changing the height of the TV module 65. The adjusting screw sleeve 21 and the bottom thread structure form a mechanical self-locking mechanism, so it will not fall down on its own even in a vibration environment. When disassembling, simply remove the top support column 12 from the bottom support cylinder 11 to achieve quick separation.

[0031] Furthermore, the top support column 12 is fitted with a top fixing sleeve 23, which is fitted with a longitudinally arranged vertical guide strip 24. The bottom support cylinder 11 is fitted with a bottom guide sleeve 25, which has a vertical guide hole 26 that slides with the vertical guide strip 24. The vertical guide hole 26 of the top fixing sleeve 23 and the bottom guide sleeve 25 slides with each other through the vertical guide strip 24, ensuring that the top support column 12 and the bottom support cylinder 11 remain coaxially connected. This provides more lateral support force to the top support column 12, preventing the top support column 12, on which the television module 65 is installed, from tilting outward, thereby improving support stability.

[0032] The connecting plate 31 is equipped with a telescopic plate 32 that can move back and forth. The telescopic plate 32 is detachably equipped with a backplate bracket 6 for supporting the TV module 65. A telescopic module 3 is movably connected between the telescopic plate 32 and the connecting plate 31. The telescopic module 3 includes two sets of folding parts. The folding parts include a first folding rod 33 and a second folding rod 34 that are movably connected in a cross manner. A first drive rod 39 is installed along the first folding rod 33.

[0033] When the front and rear positions of the TV module 65 need to be adjusted, the first folding rod 33 and the second folding rod 34 of the folding component are folded and rotated by pulling the telescopic plate 32, so as to unfold or fold and adjust the front and rear positions of the TV module 65. The TV module 65 can be extended to the center of the conference table to promote communication between the speaker and the participants and enhance the sense of participation in the meeting. When not in use, the TV module 65 can be pushed close to the wall to save floor space and keep the conference room tidy.

[0034] Specifically, the middle ends of the first folding rod 33 and the second folding rod 34 are respectively formed with middle connecting holes 35, and a middle connecting rod 36 is inserted between the two middle connecting holes 35. The first folding rod 33 and the second folding rod 34 swing around the middle connecting rod 36. The inner ends of the first folding rod 33 and the second folding rod 34 are both hinged to the connecting plate 31, and the outer ends of the first folding rod 33 and the second folding rod 34 are both hinged to the telescopic plate 32. Through the precise matching of the middle hinge points, friction during the movement of the folding rods is reduced. When the folding piece composed of the first folding rod 33 and the second folding rod 34 is unfolded, it has an X-structure, and when folded, it is continuously compressed into a straight line, so that the front and rear positions of the television module 65 can be adjusted according to the needs of the meeting.

[0035] Furthermore, the connecting plate 31 is respectively equipped with a first hinge seat 37 that is rotatably connected to the inner end of the first folding rod 33 and the second folding rod 34, and the telescopic plate 32 is respectively equipped with a second hinge seat 38 that is rotatably connected to the outer end of the first folding rod 33 and the second folding rod 34; under the action of the first hinge seat 37 and the second hinge seat 38, when the folding piece composed of the first folding rod 33 and the second folding rod 34 is unfolded, it can achieve adaptation and ensure the stability and smoothness when unfolding or folding.

[0036] Specifically, the connecting plate 31 is equipped with a telescopic drive mechanism 4 for adjusting the front and rear positions of the telescopic plate 32. The telescopic drive mechanism 4 includes a drive sleeve 5 movably mounted on the connecting plate 31, a drive threaded sleeve 51 installed inside the drive sleeve 5, and a second drive rod 45 driven by the drive threaded sleeve 51. The second drive rod 45 has an external thread structure that engages with the drive threaded sleeve 51. The drive sleeve 5 rotates to drive the second drive rod 45 to telescopically move. When adjusting the front and rear positions of the television module 65, the drive sleeve 5 is rotated, causing the drive threaded sleeve 51 to engage with the external thread structure of the second drive rod 45, which then telescopically moves the second drive rod 45. This allows for precise adjustment of the unfolding angle of the first folding rod 33. Once adjusted to the correct position, the rod automatically locks to prevent accidental slippage, significantly improving safety and ensuring balance and stability at any telescopic position.

[0037] Furthermore, the first drive rod 39 is installed between the two first folding rods 33, and the top of the second drive rod 45 is fitted with a fixed sleeve 46 connected to the first drive rod 39. The second drive rod 45 can move along the moving direction of the telescopic plate 32, thereby driving the first folding rods 33 to swing around the connecting plate 31, realizing the unfolding or folding of the angle according to the usage scenario.

[0038] Furthermore, the connecting plate 31 is provided with a movable plate 41 and a guide rail 42 for guiding the movable plate 41 to move. The movable plate 41 is formed with a guide upright plate 43, and the guide upright plate 43 is formed with a guide groove 44 along its length. The second drive rod 45 passes through the guide groove 44. The guide rail 42 restricts the position of the movable plate 41, so that the movable plate 41 can only move along the length direction of the guide rail 42. When the first folding rod 33 swings at different angles, that is, when the first drive rod 39 moves back and forth, the extension length of the first drive rod 39 is also different. Therefore, the guide rail 42 can adaptively adjust its position according to the unfolding angle of the first folding rod 33 to ensure smooth adjustment of the swing angle of the first folding rod 33. In addition, the guide groove 44 can ensure that the second drive rod 45 always remains connected to the movable plate 41 at different heights, which facilitates the adaptive adjustment of the position of the movable plate 41 along the length direction of the guide rail 42.

[0039] Specifically, the movable plate 41 is formed with a drive hole 52 for the second drive rod 45 to pass through, the connecting plate 31 is formed with a movable elongated hole 53, the drive sleeve 5 is installed on the back of the movable plate 41, the back of the movable plate 41 is equipped with a guide frame 54, the guide frame 54 is equipped with a circular ring 55, and the drive sleeve 5 is equipped with an outer ring groove 56 that mates with the circular ring 55. When the drive sleeve 5 rotates, it remains connected to the moving plate 41. When the drive sleeve 5 rotates, the internal drive screw sleeve 51 engages with the external thread structure of the second drive rod 45, making the extension and retraction length of the second drive rod 45 adjustable. When the TV module 65 needs to extend, the drive sleeve 5 is rotated in the forward direction, and the second drive rod 45 is pushed out along the length direction of the drive screw sleeve 51, so that the folding piece composed of the first folding rod 33 and the second folding rod 34 unfolds into an X-structure. Conversely, when the TV module 65 needs to retract and store, the drive sleeve 5 is rotated in the reverse direction, and the second drive rod 45 retracts along the length direction of the drive screw sleeve 51, so that the folding piece composed of the first folding rod 33 and the second folding rod 34 continuously contracts until it forms a straight structure.

[0040] The backplate bracket 6 includes a transverse fixing plate 61 horizontally mounted on the telescopic plate 32. The top of the transverse fixing plate 61 has a backward-bent guide slope 62. The transverse fixing plate 61 is fitted with a pair of parallel, spaced-apart longitudinal mounting strips 63. Each longitudinal mounting strip 63 has multiple back holes 64 along its length, which connect to the back of the television module 65. The longitudinal mounting strips 63 also have barbed grooves 66 that engage with the guide slope 62 at the top of the transverse fixing plate 61. After the television module 65 is installed and connected via the back holes 64 of the longitudinal mounting strips 63, it forms a modular structure. When subsequently installed onto the backplate bracket, the barbed grooves 66 of the longitudinal mounting strips 63 slide down the guide slope 62 of the transverse fixing plate 61, automatically aligning and positioning itself. Once in place, the barbed grooves 66 and the guide slope 62 form a mechanical self-locking mechanism to prevent accidental detachment.

[0041] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0042] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
