Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0037] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0038] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0039] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0040] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0041] As disclosed in the background art, existing display tables are usually fixed structures that can only be used as desktops. Their display angle cannot be adjusted, which means that users can only watch from around the desktop. Therefore, the display scenarios are relatively limited and cannot be viewed from a distance. The usage scenarios are also very limited.

[0042] To address the aforementioned problems, this utility model provides a novel desktop rotating support mechanism and a smart touch table. The specific structure and working principle of the desktop rotating support mechanism and the smart touch table will be described in detail below. It should be noted that, unless otherwise specified, the features in the embodiments of this utility model can be combined with each other.

[0043] See Figure 1 , Figure 2 and Figure 8 This utility model embodiment provides a desktop rotation support mechanism 100, which can realize the rotation of the display table 210, thereby realizing the adjustment of the display angle, improving the diversity of display scenarios, and making it more convenient for users to view the display table 210.

[0044] The desktop rotating support mechanism 100 provided in this embodiment includes a support base 110, a base 130, a mounting plate 150, and a rotation drive 170. The support base 110 is disposed on the ground, and the base 130 is disposed on the support base 110, with a hinge shaft 131 provided on the edge of the base 130. One edge of the mounting plate 150 is hinged to the hinge shaft 131 and configured to fit snugly against the bottom surface of the display tabletop 210. The rotation drive 170 is disposed on the base 130 and is connected to the middle of the mounting plate 150. The rotation drive 170 is configured to drive the mounting plate 150 to rotate relative to the base 130.

[0045] In actual installation, the desktop rotation support mechanism 100 can be assembled first, and then the mounting plate 150 can be attached to the bottom surface of the display table 210, while the top surface of the display table 210 is equipped with a touch screen. After assembly, when the display table 210 needs to be used as a desktop, the mounting plate 150 can be rotated to a horizontal position using the rotation drive 170. At this time, the display table 210 remains horizontal and can be used as a regular desktop. When the display table 210 needs to be used as a display screen, the mounting plate 150 can be rotated to an inclined or vertical position using the rotation drive 170. At this time, the display table 210 remains inclined or vertical and can be used as a display screen, making it convenient for users to view. The tilt angle can be adjusted to avoid surface glare. By adjusting the display angle, the versatility of display scenarios can be improved, making it more convenient for users to view the display table 210.

[0046] See Figures 2 to 4 In some embodiments, the base 130 includes a fixing box 132 and a fixing frame 133. The fixing frame 133 is connected to the bottom side of the fixing box 132, and the fixing box 132 is connected to the support base 110. A hinge shaft 131 is disposed on one side edge of the fixing box 132. A mounting plate 150 is located on the top side of the fixing box 132. A rotation drive 170 is disposed on the fixing frame 133 and passes through the fixing box 132 to connect with the mounting plate 150. Specifically, the mounting plate 150 is rotatably disposed on the top side of the fixing box 132, while the bottom side of the fixing box 132 is connected to the support base 110, which provides structural support. The hinge shaft 131 can be fixedly disposed on one side edge of the fixing box 132, while the edge of the mounting plate 150 is rotatably connected to the hinge shaft 131. The rotary drive component 170 is supported by the fixed frame 133, and the bottom end of the rotary drive component 170 is connected to the fixed frame 133, while the top end passes through the fixed box 132 and is hinged to the middle of the mounting plate 150, thereby realizing the transmission connection between the rotary drive component 170 and the mounting plate 150.

[0047] In some embodiments, a transmission seat 151 protrudes from the center of the bottom side of the mounting plate 150. The transmission seat 151 passes through the fixing box 132. The output shaft of the rotary drive 170 is hinged to the transmission seat 151 and configured to drive the transmission seat 151 to move closer to or away from the base 130, thereby causing the mounting plate 150 to rotate relative to the base 130. Specifically, the transmission seat 151 is fixedly disposed in the center of the bottom surface of the mounting plate 150 and protrudes downward. The output shaft of the rotary drive 170 is rotatably connected to the transmission seat 151, so that during the rotation of the mounting plate 150, the rotary drive 170 and the mounting plate 150 can also rotate relative to each other, avoiding interference between them.

[0048] It should be noted that, in this embodiment, a boss is provided in the middle of the bottom side of the mounting plate 150, and the transmission seat 151 can be fixedly mounted on the boss by screws. Furthermore, a first pin is provided on the bottom side of the transmission seat 151, which can be rotatably connected to the top end of the output shaft of the rotary drive 170.

[0049] In some embodiments, the fixing box 132 includes a support box body 134 and a cover plate 135. The support box body 134 is disposed on the support base 110, and the cover plate 135 covers the support box body 134. The support box body 134 has a first clearance hole 1341 for the output shaft of the rotary drive member 170 to pass through, and the cover plate 135 has a second clearance hole 1351 for the transmission seat 151 to pass through. The hinge shaft 131 is disposed on the support box body 134. Specifically, the first clearance hole 1341 and the second clearance hole 1351 are correspondingly arranged, the opening of the support box body 134 faces upward, and the cover plate 135 covers the opening of the support box body 134, so that the support box body 134 and the cover plate 135 form an internal cavity. When the mounting plate 150 is in a horizontal position, the transmission seat 151 can be accommodated in the internal cavity.

[0050] In some embodiments, both ends of the hinge shaft 131 extend out of the support housing 134, and the bottom side of the mounting plate 150 is provided with hinge lugs 153, which are rotatably sleeved on both ends of the hinge shaft 131. Specifically, the hinge shaft 131 is partially accommodated in the internal cavity, and a limiting protrusion is provided on the hinge shaft 131. This limiting protrusion is located inside the support housing 134 and can limit and abut against the inner wall of the support housing 134, thereby preventing the hinge shaft 131 from coming out of the support housing 134. The hinge lugs 153 and the two ends of the hinge shaft 131 extending out of the support housing 134 are rotatably engaged, thereby realizing the rotational connection between the mounting plate 150 and the hinge shaft 131.

[0051] In some embodiments, a resilient post 136 is provided on the side of the support housing 134 away from the hinge axis 131. The resilient post 136 extends partially out of the cover plate 135 and is configured to abut against the mounting plate 150. Specifically, the bottom end of the resilient post 136 abuts against the bottom wall of the support housing 134, and the top end of the resilient post 136 protrudes through the cover plate 135 and slightly protrudes from it, so that the mounting plate 150 can abut against the top end of the resilient post 136 when it is in a horizontal position. The resilient post 136 can be made of silicone or rubber, serving a cushioning and load-bearing function.

[0052] It should be noted that the position where the mounting plate 150 abuts against the elastic column 136 is located on the side of the transmission seat 151 away from the hinge shaft 131, thereby ensuring that the mounting plate 150 is subjected to uniform force when in a horizontal state.

[0053] See Figures 5 to 7In some embodiments, the end of the rotary drive 170 away from the mounting plate 150 is also provided with a connecting seat 171, and the fixing frame 133 is also provided with a hinge seat 172. The connecting seat 171 is hinged to the hinge seat 172, and the connecting seat 171 is configured to rotate relative to the hinge seat 172 under the drive of the rotary drive 170. Specifically, a second pin is provided on the hinge seat 172, and the connecting seat 171 is rotatably sleeved on the second pin, and can be rotatably connected to the connecting seat 171 through the second pin. Therefore, during the process of the rotary drive 170 driving the mounting plate 150 to rotate, the top end of the rotary drive 170 is rotatably connected to the transmission seat 151 through the first pin, and the bottom end is rotatably connected to the hinge seat 172 through the second pin. Therefore, the driving process of the rotary drive 170 can be smoother, avoiding interference between the upper and lower structures.

[0054] In some embodiments, the rotary drive 170 includes an electric actuator 173 and a drive motor 174, both mounted on a connecting base 171. The electric actuator 173 has an output shaft, and the drive motor 174 is driveably connected to the electric actuator 173. Specifically, the electric actuator 173 is fixedly mounted on the connecting base 171, and its output shaft is connected to a transmission base 151 via a first pin. The drive motor 174 is fixedly mounted on the connecting base 171. The drive motor 174 has a power supply wire that extends out of the support base 110 and is connected to an external power source (such as a power strip or battery). The connection structure and transmission principle of the drive motor 174 and the electric actuator 173 can be referenced from the existing electric actuator 173 structure.

[0055] Of course, in other preferred embodiments of this utility model, the rotary drive 170 may also be a cylinder or hydraulic cylinder or other drive forms, which are not specifically limited here.

[0056] In some embodiments, the mounting bracket 133 includes a carrier plate 137 and support plates 138 disposed on both sides of the carrier plate 137. The support plates 138 are connected to the bottom side of the mounting box 132, and a hinge seat 172 is disposed on the carrier plate 137. Specifically, there are two support plates 138, which are integrally disposed on both sides of the carrier plate 137 and extend upward. The top ends of the support plates 138 are bent and fixedly connected to the bottom surface of the mounting box 132 by screws. A receiving space can be formed between the two support plates 138, and the rotary drive member 170 is accommodated in the receiving space. The hinge seat 172 is integrally disposed on the carrier plate 137, which can support the rotary drive member 170 and ensure that the rotary drive member 170 can stably drive the mounting plate 150 to rotate.

[0057] In some embodiments, a reinforcing flange 139 is provided on the side of the support plate 137 adjacent to the support plate 138. Specifically, the support plate 137 is rectangular, the two support plates 138 are integrally disposed on opposite side edges of the support plate 137, and the two reinforcing flanges 139 are integrally disposed on the other two opposite edges of the support plate 137. The two reinforcing flanges 139 have different bending directions, one bending upwards and the other bending downwards. By providing the reinforcing flanges 139, the overall structural strength of the support plate 137 and the support plate 138 can be enhanced.

[0058] Please continue reading Figures 1 to 4 In some embodiments, the support base 110 includes a support chassis 111 and a support body 112. The support body 112 is disposed on the support chassis 111, the fixing box 132 is disposed on the support body 112, and the fixing frame 133 is accommodated within the support body 112. Specifically, the support body 112 can be a profile structure, with its top end connected to the fixing box 132 and its bottom end connected to the support chassis 111, thereby supporting the fixing box 132. Furthermore, the support base 110 can accommodate both the fixing frame 133 and the rotary drive component 170 within it, so that the rotary drive component 170 is not visible from the outside, making the overall appearance more aesthetically pleasing. At the same time, it can also effectively protect the internal rotary drive component 170 and reduce the overall space occupied.

[0059] In some embodiments, a plurality of rollers 113 are provided on the bottom side of the support chassis 111. The rollers 113 are configured to roll against the ground and drive the support chassis 111 to move. Specifically, the support chassis 111 may be cross-shaped and have four support arms. Each support arm is provided with a roller 113 at its end, so that the four rollers 113 can achieve the functions of support and movement.

[0060] Furthermore, each roller 113 is equipped with a self-locking block 114, which is configured to selectively restrict the rolling of the roller 113. Multiple rollers 113 achieve a self-locking function through the self-locking blocks 114, locking themselves in place to prevent free movement. The rollers 113 can be omnidirectional wheels for convenient multi-directional movement.

[0061] See Figure 8This utility model embodiment also provides an intelligent touch table 200, including a display tabletop 210 and a desktop rotation support mechanism 100 as described above. The desktop rotation support mechanism 100 includes a support base 110, a base 130, a mounting plate 150, and a rotation drive component 170. The support base 110 is disposed on the ground, and the base 130 is disposed on the support base 110, with a hinge shaft 131 provided on the edge of the base 130. One edge of the mounting plate 150 is hinged to the hinge shaft 131. The rotation drive component 170 is disposed on the base 130 and is connected to the middle of the mounting plate 150. The rotation drive component 170 is configured to drive the mounting plate 150 to rotate relative to the base 130. A touch screen is provided on the top side surface of the display table 210, and the mounting plate 150 is attached to the bottom side surface of the display table 210. The rotation drive 170 is configured to drive the mounting plate 150 and the display table 210 to rotate relative to the base 130 to adjust the display tilt angle of the touch screen.

[0062] In some embodiments, a touch display screen is embedded in the top surface of the display table 210. The touch display screen is one of a resistive touch screen, a capacitive touch screen, an infrared touch screen, or a surface acoustic wave touch screen, and its basic display principle and touch principle can refer to existing touch display screens. Furthermore, components such as a processor, communication device, audio device, and battery module can be installed within the display table 210.

[0063] The intelligent touch table 200 provided in this embodiment integrates a touch screen on the top surface of the display tabletop 210, enabling display and touch functions. Driven by the rotation drive 170, the display tabletop 210 can switch between a flat position and a flipped position. In actual use, when a tabletop is needed, the display tabletop 210 can be laid flat using the rotation drive, thus functioning as a regular touch table and integrating intelligent functions such as mahjong or board games through the touch screen. When watching movies, the tilt angle of the display tabletop 210 can be adjusted using the rotation drive 170, allowing the touch screen on the display tabletop 210 to face the viewer, acting as a screen to maintain viewing and enabling video viewing or presentations. Furthermore, when storage is required, the display tabletop 210 can be adjusted to a completely vertical position using the rotation drive 170, reducing its space occupation.

[0064] In summary, this embodiment of the invention places the base 130 on the support base 110, and the edge of the base 130 is provided with a hinge shaft 131. One edge of the mounting plate 150 is hinged to the hinge shaft 131, and the mounting plate 150 is fitted to the bottom surface of the display table 210. The rotation drive 170 is disposed on the base and is connected to the middle of the mounting plate 150, thereby driving the mounting plate 150 to rotate relative to the base 130, which in turn drives the display table 210 to rotate, thereby adjusting the display angle of the display table 210. The desktop rotation support mechanism 100 provided by this embodiment of the invention can realize the rotation of the display table 210, thereby realizing the adjustment of the display angle, improving the diversity of display scenarios, making it more convenient for users to view the display table 210, and is also easy to store with a small storage space.
