Technical Field

[0001] This utility model relates to the technical field of multi-functional conference machines with capacitive and electromagnetic touch, specifically, to a multi-functional conference machine with capacitive and electromagnetic touch. Background Technology

[0002] With the development of the times, existing conference machines usually have functions such as video, voice and display, and have gradually become an indispensable device in daily meetings, which can meet various meeting needs.

[0003] Currently, conference machines on the market typically include a capacitive electromagnetic touch screen, a screw, a telescopic inner rod, a telescopic outer rod, a base, and casters. The capacitive electromagnetic touch screen is connected to the telescopic inner rod on both sides. The telescopic inner rod and the telescopic outer rod have connection holes for fixing to the screw. When the capacitive electromagnetic touch screen is adjusted to the required height, the position of the telescopic inner rod and the telescopic outer rod is fixed by the screw.

[0004] Over time, dust accumulates on the threads of the screw on this type of conference machine, and it gradually wears down. This can cause the screw to jam or even become stuck during rotation, making it difficult to adjust the height of the capacitive electromagnetic touchscreen and resulting in a short lifespan.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] like Figures 1-6 As shown in the figure, this embodiment proposes a multi-functional conference machine with a capacitive and electromagnetic touch screen, including a capacitive electromagnetic touch screen 1, a lifting slide 2, casters 3, a base 4, a connecting plate 5, and a lifting transmission mechanism 201. The conference machine in this embodiment uses a capacitive electromagnetic touch screen 1 as its display. This touch screen has many advantages. For example, the capacitive electromagnetic touch screen 1 can simultaneously detect capacitance and electromagnetic signals, thus having higher sensitivity and accuracy. Users only need to lightly touch the screen to complete the operation, without having to press the screen forcefully, making the capacitive electromagnetic touch screen 1 easier to use. The capacitive electromagnetic touch screen can simultaneously detect the contact of multiple points, thus realizing multi-touch functionality. Users can use multiple fingers to operate, such as zooming, rotating, and dragging, which improves interactivity and user experience. The capacitive electromagnetic touch screen 1 does not require pressure, so it can be made of non-mechanical materials, such as glass or plastic film. Such materials have high transparency, providing a clearer and brighter display effect for the touch screen. This gives the capacitive electromagnetic touch screen advantages such as high sensitivity, multi-touch, and high transparency.

[0027] The conference machine's base features a lifting slide on one side; the base of the multi-functional conference machine with capacitive electromagnetic touchscreen 1 is equipped with casters 3, which can rotate freely in any direction, allowing for more flexible turning and movement. The casters 3 reduce friction with the ground because they can rotate freely, unlike traditional wheels that need to roll, thus reducing wear and noise caused by friction. The casters 3 also enable the multi-functional conference machine with capacitive electromagnetic touchscreen 1 to maintain balance and stability on different terrains. They can adaptively adjust the angle and speed of each wheel to adapt to different ground elevations and inclinations, providing better stability and control.

[0028] The lifting function of the capacitive electromagnetic touchscreen 1 is controlled by the lifting transmission mechanism 201 within the lifting slide 2. By combining the capacitive electromagnetic touchscreen 1 with the lifting slide, the height and angle of the display can be freely adjusted according to the user's height and needs. This helps ensure that employees maintain correct posture and good neck and eye health during work. The combination of the lifting slide 2 and the capacitive electromagnetic touchscreen 1 is highly flexible and suitable for various meeting room environments and needs. Whether standing or sitting during a meeting, users can freely adjust the height of the touchscreen as needed, providing a more personalized and comfortable experience.

[0029] The lifting slide 2 is fixedly connected to the capacitive touchscreen 1 via the connecting plate 5. The bolt holes of the lifting slide 2 are fixedly connected to the surface bolt holes of the connecting plate, and the bolt holes on the edge of the connecting plate 5 are fixedly connected to the bolt holes on the back of the capacitive touchscreen 1, thus achieving linkage between the lifting slide 2 and the capacitive touchscreen 1. The edge of the connecting plate 5 is also equipped with an anti-slip pad 501, which is fixed to the connection point between the connecting plate 5 and the capacitive touchscreen 1 by bolts. The anti-slip pad 501 increases the friction at the connection point, making the connection more secure. When the connection point is subjected to external force or vibration, the anti-slip pad 501 provides additional friction to prevent loosening or slippage. The connection point between the connecting plate 5 and the capacitive touchscreen 1 typically bears a certain amount of pressure. The anti-slip pad 501 helps to distribute this pressure and reduce pressure concentration in a small area. This helps protect the connection point from wear and damage. Adding the anti-slip pad 501 improves connection stability, extends connection lifespan, and provides better safety and performance. The lifting slide 2 is equipped with a lifting transmission mechanism 201, which includes an auxiliary fixing device 6, a motor 7, a drive pulley 8, a synchronous belt 9, a slide rail 10, a driven pulley 12, and a pressure plate 13. The output shaft of the motor 7 is connected to the drive pulley 8, resulting in high power transmission efficiency: through the connection between the output shaft of the motor 7 and the drive pulley 8, the motor provides power, causing the drive pulley to rotate, and the power is transmitted to the driven pulley 12 through the engagement of the synchronous belt 9. This design achieves efficient power transmission and reduces energy loss. Good speed synchronization: because both the drive pulley 8 and the driven pulley 12 are engaged with the synchronous belt 9, their speeds can remain synchronized. This helps ensure the stability and accuracy of the lifting transmission mechanism. Low noise: compared to other transmission methods, such as gear transmission, synchronous belt transmission has lower noise. The synchronous belt operates smoothly with low friction noise, resulting in a relatively quiet overall operation. Low maintenance cost: synchronous belts have a long service life and low maintenance costs. Compared to other transmission mechanisms, such as chain transmission or gear transmission, the replacement and maintenance of synchronous belts are relatively simple and cost-effective. When the motor 7 is powered on, it will drive the lifting transmission mechanism 201 of the lifting slide 2 to work together, so that the capacitive electromagnetic touch screen 1 can be raised and lowered.

[0030] This utility model incorporates two sets of lifting transmission mechanisms 201. The advantages of having two sets are: increased load-bearing capacity: By using two sets of lifting transmission mechanisms 201, the load can be evenly distributed across each lifting transmission mechanism 201, effectively improving the overall system's load-bearing capacity. This increases the stability and safety of the lifting device and allows it to adapt to larger load requirements. Increased redundancy: This redundancy design reduces downtime and improves equipment reliability and availability. Load balancing: In some situations, the working environment may be uneven, and the load may be unevenly distributed across the lifting device. Using two sets of lifting transmission mechanisms 201 allows for better load balancing, ensuring a more even load distribution across each lifting transmission mechanism 201 and reducing wear and tear and the risk of failure. Improved speed and efficiency: By using two sets of lifting transmission mechanisms 201 simultaneously, higher lifting speeds and higher efficiency can be achieved. The two sets of lifting transmission mechanisms 201 can work simultaneously, providing power together, thereby accelerating the lifting device's operating speed and improving work efficiency.

[0031] The slide rail 10 is equipped with a sliding structure for the roller assembly 601 to slide and connect. The sliding structure is a U-shaped limiting track 11. The roller assembly 601 contains side-by-side rollers 603, which contact the limiting track 11, allowing the rollers 603 to move within the limiting track 11. The U-shaped limiting track 11 helps the rollers 603 maintain the correct track position, preventing them from deviating or disengaging from the slide rail. Each roller 603 includes a multi-row ball bearing 606. The cooperation between the rollers 603 and the multi-row ball bearing 606 offers several advantages. For example, the multi-row ball bearing 606 contains many rollers, which reduce friction between the rollers and the shaft, thus providing smooth rolling contact. Because the multi-row ball bearing 606 contains multiple rolling elements, it can withstand larger radial and axial loads. Compared to single-row ball bearings or ball bearings, multi-row ball bearings 606 can withstand greater loads within the same dimensions. This gives them an advantage in applications requiring high load capacity. Because they contain multiple rolling elements, multi-row ball bearings 606 can automatically adjust for misalignment during installation or use, helping to maintain a good fit between the bearing and the housing bore and improving operational stability. Multi-row ball bearings 606 have significant advantages in load-carrying capacity and self-aligning capability, making them suitable for engineering machinery and equipment requiring high loads, high-speed rotation, and a certain degree of tilt angle.

[0032] The auxiliary retainer 6 contains a roller 603, inside which is a multi-row ball bearing 606. The multi-row ball bearing 606 is fixedly connected to the auxiliary retainer 6 by bolts. The surface of the auxiliary retainer 6 has several fixing holes 607, which not only fix the roller to the roller assembly, but also allow lubricant to be added to the multi-row ball bearing 606 through the fixing holes 607. This lubricant forms a thin lubricating film between the roller 603 and the slide rail 10, reducing friction between the roller and the slide rail 10 and providing smooth movement. The lubricant has high viscosity and adhesion, providing better cushioning and shock absorption when the multi-row ball bearing 606 is subjected to impact or vibration. This helps protect the multi-row ball bearing from damage by external forces and improves the reliability and stability of the system. Compared to conference machines on the market that consist of a capacitive electromagnetic touch screen, screw, telescopic inner rod, telescopic outer rod, base, and casters, this conference machine allows users to easily adjust the height of the capacitive electromagnetic touch screen and also extends the service life of the conference machine.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
