Description

Technical Field

[0001] This invention relates to the field of video conferencing terminal technology, and more specifically, to a high-definition video conferencing terminal capable of local image loop output. Background Technology

[0002] A video conferencing system is an application system that supports real-time information exchange and collaborative work across geographical boundaries via a network. It transmits video and audio data in real time through connected video and audio capture devices, enabling real-time and intuitive audio-visual communication among collaborating personnel over long distances. Furthermore, leveraging multimedia technology, the system allows users to collaboratively handle work-related information, such as interactive whiteboards, document sharing, screen sharing, media sharing, remote control, and application sharing, thus creating a shared virtual workspace—a network conference room.

[0003] In local meeting room use, existing high-definition video conferencing terminals are popular because they can achieve image loop output. However, in actual use, the screen angle is not easy to adjust, resulting in a relatively rigid screen usage range, which in turn limits the smoothness of video conferencing.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

[0005] To address the problems in related technologies, this invention proposes a high-definition video conferencing terminal capable of local image loop output, thereby overcoming the aforementioned technical issues in existing related technologies.

[0006] Therefore, the specific technical solution adopted by the present invention is as follows:

[0007] A high-definition video conferencing terminal capable of local image loop output includes a housing fitted into a wall. The wall has a fitting groove that mates with the housing. A recess is located on the top of the housing, within which a drive mechanism is housed. A display screen is mounted on the drive mechanism. The drive mechanism includes two fixing plates located on the inner wall of one side of the recess. Each fixing plate has a track groove and a check groove. A check groove contains a check component. A fixing rod is located at the top of the track groove, and a connecting plate is fitted onto the fixing rod. The two connecting plates are connected by a connecting shaft, allowing the side of one connecting plate to move. A push rod is connected to the housing, and a rotating rod is movably connected to the other end of the push rod. The other end of the rotating rod is connected to a motor shaft, and the other end of the motor shaft extends through to the other side of the fixed plate and is connected to a motor. The other end of the connecting plate is connected to the display screen. A cover plate is hinged to the other side of the housing. A limiting component that cooperates with the limiting block is provided on the side of the housing. A movable groove is provided on the side of the cover plate. An infrared sensor is provided on one side inside the movable groove. A movable component is fitted inside the movable groove. A connecting component is connected to the other end of the movable component. The other end of the connecting component is movably connected to the end of the display screen.

[0008] Preferably, the check valve assembly includes a slide rail located on the inner wall of the check valve groove, a slider sleeved on the slide rail, a guide rod sleeved on each of the inner sides of the check valve groove, the two guide rods being connected by a pressing plate, a spring being provided on the outer surface of the guide rod above the pressing plate, an electric telescopic rod being provided at the inner top of the check valve groove between the two guide rods, the output end of the electric telescopic rod contacting the bottom of the pressing plate, and through holes being provided at both ends of the pressing plate to cooperate with the guide rods.

[0009] Preferably, the limiting component includes a spring groove located on the side of the cover plate and a side plate located on the side of the housing. A second spring is provided in the spring groove, and a limiting block is provided at the other end of the second spring. A track groove is provided on the outer surface of the side plate, and a limiting groove is provided in the track groove. The end of the limiting block extends into the limiting groove.

[0010] Preferably, the connector includes a first separation block and a second separation block. At the junction of the first separation block and the second separation block, an adsorption block and an electromagnet are respectively provided. The adsorption block and the electromagnet are adsorbed together. The second separation block has a traction component that cooperates with the first separation block inside.

[0011] Preferably, the traction assembly includes a storage groove located inside the second separation block, a second motor is provided inside the storage groove, a winding wheel is provided at the output end of the second motor, a traction rope is wound on the winding wheel, and a connecting groove is provided on the outer surface of the first separation block, the other end of the traction rope passes through the outer surface of the first separation block and is connected in the connecting groove.

[0012] Preferably, the storage groove is provided with several positioning rollers that cooperate with the traction rope.

[0013] The beneficial effects of this invention are as follows:

[0014] Through the design of the drive mechanism, the display screen and the cover can be rotated and unfolded, thereby adjusting the angle of the display screen to meet complex and diverse usage needs and adapt to various usage environments.

[0015] Through the design of the check valve assembly, the connecting plate gradually squeezes the slider while rotating. As the connecting plate rotates, the slider gradually moves towards the top of the check valve groove. As the slider moves upward, it squeezes the compression plate, which in turn squeezes the spring. As the connecting plate rotates, the end of the connecting plate gradually separates from the slider. At this time, the spring releases its elastic force to push the compression plate and the slider to descend and reset. The descending slider will limit the connection plate. When the drive mechanism malfunctions and the display screen suddenly falls back, the slider can block the connecting plate, thereby preventing the descending connecting plate from colliding with the inner wall of the housing and causing structural damage.

[0016] Through the design of the limiting component, as the cover plate moves, the limiting block gradually enters the track groove. During the entry process, under the action of the hemispherical end of the limiting block, it moves and is stored in the spring groove and simultaneously squeezes the second spring. After entering the limiting groove, the limiting block is locked into the limiting groove under the action of the second spring. At this time, it only performs a preliminary positioning of the cover plate, not fixation. When it is stored, when the connecting piece pulls the cover plate, this pulling force will pull the cover plate. Under the guidance of the hemispherical end, the limiting block on the cover plate will disengage from the limiting groove and enter the track groove. Thus, when unfolding, the cover plate can be initially fixed. When storing, it does not affect the connecting piece pulling the cover plate to rotate and store it.

[0017] The design of the traction component ensures that the display screen and cover plate do not interfere with each other when they are unfolded, and the connection between the display screen and cover plate can be reconnected when the display screen is folded up and stored.

A connector 16 is connected to the other end of the movable part 17. The other end of the connector 16 is movably connected to the end of the display screen 9.

[0031] Example 2, as Figure 1-7As shown, a high-definition video conferencing terminal capable of local image loop output according to an embodiment of the present invention includes a housing 1, which is fitted into a wall. The wall has a fitting groove that mates with the housing 1. A groove 2 is provided on the top of the housing 1, and a driving mechanism is located within the groove 2. A display screen 9 is mounted on the driving mechanism. The driving mechanism includes two fixing plates 3 located on the inner wall of one side of the groove 2. A track groove 4 and a check groove 5 are provided on the fixing plates 3. A check component is located within the check groove 5. A fixing rod 6 is provided on the top of the track groove 4. A connecting plate 8 is fitted onto the fixing rod 6. The two connecting plates 8 are connected by a connecting shaft 7. A push rod 20 is movably connected to the side of one connecting plate 8.

The other end of the motor shaft extends through to the other side of the fixing plate 3 and is connected to a motor 10. The other end of the connecting plate 8 is connected to the display screen 9. A cover plate 18 is hinged to the other side of the housing 1. A limiting component that cooperates with the limiting block 24 is provided on the side of the housing 1. A movable groove 19 is provided on the side of the cover plate 18. An infrared sensor 21 is provided on one side inside the movable groove 19. A movable component 17 is fitted inside the movable groove 19. The other end of the movable component 17 is connected to a connector 16. The other end of the connector 16 is movably connected to the end of the display screen 9. The check valve assembly includes a slide rail 11 located on the inner wall of the check valve groove 5. A slider 12 is fitted onto the upper part of the check groove 5. A guide rod 13 is fitted onto each of the two inner sides of the check groove 5. The two guide rods 13 are connected by a pressing plate 14. A spring 15 is provided on the outer surface of the guide rod 13 above the pressing plate 14. An electric telescopic rod 38 is provided at the top inner part of the check groove 5 between the two guide rods 13. The output end of the electric telescopic rod 38 contacts the bottom of the pressing plate 14. Both ends of the pressing plate 14 have through holes that mate with the guide rods 13. From the above design, it is clear that through the design of the check assembly, when the drive mechanism malfunctions and the display screen 9 suddenly falls, the slider 12 can block the connecting plate 8, thereby preventing the descending connecting plate 8 from colliding with the inner wall of the housing 1 and causing structural damage.

[0032] Example 3, as Figure 1-7As shown, a high-definition video conferencing terminal capable of local image loop output according to an embodiment of the present invention includes a housing 1, which is fitted into a wall. The wall has a fitting groove that mates with the housing 1. A groove 2 is provided on the top of the housing 1, and a driving mechanism is provided within the groove 2. A display screen 9 is mounted on the driving mechanism. The driving mechanism includes two fixing plates 3 located on the inner wall of one side of the groove 2. A track groove 4 and a check groove 5 are provided on the fixing plates 3. A check component is provided within the check groove 5. A fixing rod 6 is provided on the top of the track groove 4. A connecting plate 8 is sleeved on the fixing rod 6. The two connecting plates 8 are connected by a connecting shaft 7. A push rod 20 is movably connected to the side of one of the connecting plates 8. A rotating rod 39 is movably connected to the other end of the push rod 20. The other end of the rotating rod 39 is connected to a motor shaft, and the other end of the motor shaft extends through the fixing plate 3. The other side is connected to the motor 10, and the other end of the connecting plate 8 is connected to the display screen 9. The other side of the housing 1 is hinged with a cover plate 18. The side of the housing 1 is provided with a limiting component that cooperates with the limiting block 24. The side of the cover plate 18 is provided with a movable groove 19. An infrared sensor 21 is provided inside the movable groove 19. A movable part 17 is sleeved inside the movable groove 19. The other end of the movable part 17 is connected to a connector 16. The other end of the connector 16 is movably connected to the end of the display screen 9. The limiting component includes a spring groove 22 located on the side of the cover plate 18 and a side plate 25 located on the side of the housing 1. A second spring 23 is provided in the spring groove 22. The other end of the second spring 23 is provided with a limiting block 24. The outer surface of the side plate 25 is provided with a track groove 26. A limiting groove 27 is provided in the track groove 26. The end of the limiting block 24 passes through the limiting groove 27. It is easy to see from the above design that, through the design of the limiting component, when the display screen 9 is rotated and unfolded, the cover plate 18 can be initially positioned, but not fixed. When it is stored, when the connecting plate 8 pulls the cover plate 18, this pulling force will pull the cover plate 18, and the limiting block 24 on the cover plate 18 will be guided by the hemispherical end to disengage from the limiting groove 27 and enter the track groove 26. Thus, when unfolded, the cover plate 18 can be initially fixed, and when stored, it will not affect the connecting piece 16 from pulling the cover plate 18 to rotate and store it.

[0033] Example 4, as Figure 1-7As shown, a high-definition video conferencing terminal capable of local image loop output according to an embodiment of the present invention includes a housing 1, which is fitted into a wall. The wall has a fitting groove that mates with the housing 1. A groove 2 is provided on the top of the housing 1, and a driving mechanism is disposed within the groove 2. A display screen 9 is mounted on the driving mechanism. The driving mechanism includes two fixing plates 3 located on the inner wall of one side of the groove 2. Track grooves 4 and check grooves 5 are provided on the fixing plates 3. A check component is disposed within the check groove 5, and a fixing rod is provided on the top of the track groove 4. 6. A connecting plate 8 is sleeved on the fixed rod 6. The two connecting plates 8 are connected by a connecting shaft 7. A push rod 20 is movably connected to the side of one of the connecting plates 8. The other end of the push rod 20 is movably connected to a rotating rod 39. The other end of the rotating rod 39 is connected to a motor shaft. The other end of the motor shaft passes through to the other side of the fixed plate 3 and is connected to a motor 10. The other end of the connecting plate 8 is connected to the display screen 9. A cover plate 18 is hinged to the other side of the housing 1. A limiting component that cooperates with the limiting block 24 is provided on the side of the housing 1. The cover plate 18 has a movable groove 19 on its side. An infrared sensor 21 is provided inside one side of the movable groove 19. A movable component 17 is fitted inside the movable groove 19. The other end of the movable component 17 is connected to a connector 16. The other end of the connector 16 is movably connected to the end of the display screen 9. The connector 16 includes a first separation block 28 and a second separation block 29. An adsorption block 30 and an electromagnet 31 are respectively provided at the junction of the first separation block 28 and the second separation block 29. The adsorption block 30 and the electromagnet 31 are attracted together. The second separation block 29... The 9th panel has an internal traction assembly that cooperates with the first separation block 28. The traction assembly includes a storage groove 32 located inside the second separation block 29. A second motor 33 is located inside the storage groove 32. A winding wheel 34 is located at the output end of the second motor 33, and a traction rope 35 is wound around the winding wheel 34. A connecting groove 37 is located on the outer surface of the first separation block 28. The other end of the traction rope 35 passes through the outer surface of the first separation block 28 and connects to the connecting groove 37. Several positioning rollers 36 that cooperate with the traction rope 35 are located inside the storage groove 32. From the above design, it is easy to see that the traction assembly design ensures that the display screen 9 and the cover plate 18 do not interfere with each other when unfolded, and that the connection between the display screen 9 and the cover plate 18 can be reconnected when the display screen 9 is retracted for storage.

[0034] In practical applications, during use, firstly, motor 10 is started by controlling the switch. Motor 10 drives the rotating rod 39 to rotate. The other end of the rotating rod 39 pushes the connecting plate 8 to rotate around the fixed rod 6 via the push rod 20. The connecting plate 8 drives the connecting shaft 7 to rotate synchronously with the display screen 9. While rotating, the connecting plate 8 will squeeze the check valve assembly. (While rotating, the connecting plate 8 will gradually squeeze the slider 12. As the connecting plate 8 rotates, the slider 12 gradually moves towards the inner top of the check valve groove 5. As the slider 12 moves upward, it will squeeze the compression plate 14. The compression plate 14 squeezes the spring 15. As the connecting plate 8 rotates, the connecting...) As the end of plate 8 gradually disengages from slider 12, spring 15 releases its elastic force, pushing the pressing plate 14 and slider 12 to descend and reset. The descending slider 12 limits the connection plate 8. When the drive mechanism malfunctions and the display screen 9 suddenly falls back, slider 12 can block the connection plate 8, thus preventing the descending connection plate 8 from colliding with the inner wall of the housing 1 and causing structural damage. As the display screen 9 rotates and unfolds, the end of the display screen 9 will lift the cover plate 18 through connector 16. As the display screen 9 unfolds, the cover plate 18 also gradually unfolds. At the same time, the other end of connector 16 will drive the movable part 17 to move. The screen 9 moves within the slot 19. When the screen 9 and the cover 18 rotate to the point where they are about to interfere with each other, the movable part 17 also moves to the infrared sensor 21 at the end of the movable slot 19, thereby activating motor 23 to shut off electromagnet 31. After electromagnet 31 is de-energized, there is no attraction between it and the adsorption block 30. At the same time, motor 23 will extend the traction rope 35. Subsequently, as the screen 9 rotates, the traction rope 35 will also extend synchronously. At this time, the cover 18, along with the limiting block 24, rotates and moves into the limiting slot 27. (As the limiting block 24 moves with the cover 18, it will gradually enter the track slot 26. During the entry process, the limiting block 24 will...) Under the action of the hemispherical end of block 24, it will move and be stored in the spring groove 22 and simultaneously squeeze the second spring 23. After entering the limiting groove 27, the limiting block 24 will be stuck in the limiting groove 27 under the action of the second spring 23. At this time, it is only a preliminary positioning of the cover plate 18, not a fixation. When it is stored, when the connecting piece 16 pulls the cover plate 18, this pulling force will pull the cover plate 18. Under the guidance of the hemispherical end, the limiting block 24 on the cover plate 18 will be separated from the limiting groove 27 and enter the track groove 26. Thus, when unfolded, the cover plate 18 can be initially fixed. When stored, it does not affect the connecting piece 16 pulling the cover plate 18 to rotate and store it.After using the display screen 9, the drive mechanism and electric telescopic rod 38 are restarted. The electric telescopic rod 38 drives the pressing plate 14 to rise, thus not affecting the rotation and reset of the connecting plate 8. When the drive mechanism drives the display screen 9 to rotate and reset, the second motor 33 also drives the winding wheel 34 to rotate, thereby storing the traction rope 35. Then, when the display screen 9 is about to contact the cover plate 18, the traction rope 35 can pull the separation block 28, so that the adsorption blocks 30 on both separation block 28 and separation block 29 can be attracted together with the electromagnet 31, thus splicing them into the connecting piece 16. When the display screen 9 is subsequently stored, it can drive the cover plate 18 to descend and be stored in the groove 2 simultaneously.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
