Technical Field
[0001] This utility model relates to the field of smart blackboard technology, and in particular to an interconnected blackboard sub-board structure applied to capacitive and infrared blackboards. Background Technology
[0002] A smart blackboard consists of a main screen and a secondary screen. In practice, the main screen can be either capacitive or infrared touch, and the secondary screen can also be either capacitive or infrared touch. To save costs, the secondary screen usually uses infrared touch. However, if the wall is uneven or the installation is not standardized, the infrared rays emitted by the infrared transmitter may not be perfectly parallel to the screen of the infrared smart blackboard, leading to problems such as infrared interference, poor touch performance, and touch writing deviation. Therefore, the installation of an infrared smart blackboard requires that the main screen and the secondary screen be as close to the same plane as possible. This type of smart blackboard has high requirements for the flatness of the installation. The capacitive touch secondary screen does not have this problem. In order to make the infrared secondary screen (saving costs) more compatible with both capacitive and infrared touch main screens, it is necessary to propose a new solution. Utility Model Content
[0003] In view of this, the present invention addresses the deficiencies of the prior art, and its main objective is to provide an interconnected blackboard sub-board structure for capacitive and infrared blackboards, which solves the aforementioned problems.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: An interconnected blackboard sub-board structure for capacitive and infrared blackboards includes a main screen, a sub-screen, an upper mounting component, and a lower mounting component; the main screen is a capacitive touch screen or an infrared touch screen; the sub-screen is an infrared touch-sensing device, the sub-screen is located to the side of the main screen, the back of the top of the sub-screen has a rearward protrusion of an upper support protrusion, the upper support protrusion has multiple through holes at both ends, and the back of the bottom of the sub-screen has a rearward protrusion of a lower support protrusion; The upper mounting assembly includes an upper fixing support profile for fixing to a wall, an adjustable upper adjusting plate, two first adjusting screws, and multiple first fixing screws. The upper fixing support plate has an upper groove with an upward opening extending along its length. The bottom of both ends of the upper fixing support plate has threaded holes for the upper screws that extend into the upper groove. The upper adjusting plate is fitted into the upper groove and can move up and down. The bottom of both ends of the upper adjusting plate has locking grooves corresponding to the positions of the two aforementioned threaded holes for the upper screws. The two first adjusting screws are respectively fixed to the upper fixing support profile. The bottom of the fixed support plate is screwed upward into the corresponding upper screw thread hole and fits against the corresponding locking groove. The tilt angle of the upper adjustment plate can be finely adjusted by the height difference between the two first adjustment screws. The upper surface of the upper adjustment plate has multiple upper fixing thread holes. Multiple first fixing screws pass through the corresponding upper through holes and are screwed into the corresponding upper fixing thread holes, thereby fixing the aforementioned upper support protrusion onto the upper adjustment plate. Furthermore, the diameter of the first fixing screw is smaller than that of the upper through hole, thereby adjusting the position of the aforementioned upper support protrusion in the radial direction of the upper through hole. The lower mounting assembly includes a lower fixing support profile for fixing to the wall, an L-shaped support profile, multiple second fixing screws, and multiple third fixing screws. The front sides of both ends of the lower fixing support profile are provided with front and rear extending lower fixing threaded holes. The first side of the L-shaped support profile fits and supports the bottom surface of the lower support protrusion, and the two are connected and fixed by multiple third fixing screws. The second side of the L-shaped support profile has multiple through holes. Multiple second fixing screws pass through the corresponding through holes and are screwed into the corresponding lower fixing threaded holes, thereby fixing the L-shaped support profile to the lower fixing support profile. Furthermore, the diameter of the second fixing screws is smaller than that of the through holes, so that the position can be adjusted so that the first side of the L-shaped support profile fits and supports the bottom surface of the lower support protrusion.
[0005] As a preferred embodiment, the upper fixed support profile, the upper adjustable plate, the lower fixed support profile, and the L-shaped support profile are all made of aluminum alloy.
[0006] As a preferred embodiment, the first adjusting screw is fitted with a fastening nut on the rod body located below the upper fixed support profile.
[0007] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, its main features are: The independent height adjustment of the two first adjusting screws in the upper mounting assembly allows for precise control of the sub-screen's left and right tilt angles. Combined with the clearance fit between the first fixing screw and the upper through hole, fine-tuning of the sub-screen's horizontal displacement is also possible. The L-shaped support profile and the lower fixed support profile in the lower mounting assembly work together to support flexible vertical adaptation, primarily serving a supporting function. The structure of this application effectively adjusts and compensates for uneven wall surfaces and accumulated installation errors, ensuring that the sub-screen and main screen are always on the same plane, resolving infrared touch interference issues caused by flatness deviations, and providing better compatibility with capacitive and infrared touch main screens.

[0013] Please see Figures 1 to 9 This utility model embodiment provides an interconnected blackboard sub-board structure for capacitive and infrared blackboards, including a main screen 10, a sub-screen 20, an upper mounting component 30, and a lower mounting component 40; the main screen 10 is a capacitive touch screen or an infrared touch screen; the sub-screen 20 is an infrared touch sensing type, the sub-screen 20 is disposed on the side of the main screen 10, the back of the top of the sub-screen 20 is provided with an upper support protrusion 21 protruding backward, the upper support protrusion 21 has multiple through holes 22 at both ends, and the back of the bottom of the sub-screen 20 is provided with a lower support protrusion 23 protruding backward; The upper mounting assembly 30 includes an upper fixing support profile 31 for fixing to a wall, an adjustable upper adjusting plate 32, two first adjusting screws 33, and a plurality of first fixing screws 34. The upper fixing support plate has an upper groove 311 with an upward opening extending along its length. The bottom of both ends of the upper fixing support plate has upper screw threaded holes 312 that penetrate into the upper groove 311. The upper adjusting plate 32 is fitted into the upper groove 311 and can move up and down. The bottom of both ends of the upper adjusting plate 32 has locking grooves 321 corresponding to the positions of the two aforementioned upper screw threaded holes 312. The two first adjusting screws 33 are respectively fixed from the upper... The bottom of the support plate is screwed upward into the corresponding upper screw thread hole 312 and fits against the corresponding locking groove 321. The tilt angle of the upper adjustment plate 32 in the left and right directions is finely adjusted by the height difference between the two first adjustment screws 33. The upper surface of the upper adjustment plate 32 is provided with multiple upper fixing thread holes 322. Multiple first fixing screws 34 pass through the corresponding upper through holes 22 and are screwed into the corresponding upper fixing thread holes 322, thereby fixing the aforementioned upper support protrusion 21 onto the upper adjustment plate 32. Furthermore, the diameter of the first fixing screws 34 is smaller than that of the upper through holes 22, thereby adjusting the position of the aforementioned upper support protrusion 21 in the radial direction of the upper through holes 22. The lower mounting assembly 40 includes a lower fixing support profile 41 for fixing to the wall, an L-shaped support profile 42, a plurality of second fixing screws 43 and a plurality of third fixing screws 44. The front sides of both ends of the lower fixing support profile 41 are provided with front and rear extending lower fixing threaded holes (not shown in the figure). This is a conventional structure, similar to the above, and will not be described again here.
[0014] The first side of the L-shaped support profile 42 is adapted to fit and support the bottom surface of the lower support protrusion 23, and the two are connected and fixed by multiple second fixing screws 43. It should be noted that the screw fixing structure between the first side of the L-shaped support profile 42 and the lower support protrusion 23 is also a large through hole with screws, which makes it easy to adjust the relative position between the two. Since it is a conventional technology, it will not be described in detail here. The second side of the L-shaped support profile 42 has multiple through holes (not shown in the figure), which is a conventional structure and similar to the above, so it will not be described in detail here. Multiple third fixing screws 44 pass through the corresponding through holes and are screwed into the corresponding lower fixing threaded holes, thereby fixing the L-shaped support profile 42 to the lower fixing support profile 41. Furthermore, the diameter of the third fixing screws 44 is smaller than the through holes, so that the position can be adjusted so that the first side of the L-shaped support profile 42 fits and supports the bottom surface of the lower support protrusion 23.
[0015] The independent height adjustment of the two first adjusting screws 33 in the upper mounting component 30 allows for precise control of the left and right tilt angles of the sub-screen 20. Combined with the clearance fit between the first fixing screw 34 and the upper through hole 22, fine-tuning of the horizontal displacement of the sub-screen 20 is also possible. The L-shaped support profile 42 and the lower fixed support profile 41 in the lower mounting component 40 cooperate to support flexible vertical adaptation, primarily serving a supporting function. The structure of this application effectively adjusts and compensates for uneven wall surfaces and accumulated installation errors, ensuring that the sub-screen 20 and the main screen 10 are always on the same plane, resolving the infrared touch interference problem caused by flatness deviation, and providing better compatibility with capacitive touch and infrared touch main screens 10.
[0016] Furthermore, the upper fixed support profile 31, the upper adjusting plate 32, the lower fixed support profile 41, and the L-shaped support profile 42 are all made of aluminum alloy, which ensures lightweight while possessing high strength and resistance to deformation.
[0017] Furthermore, a fastening nut 35 is screwed onto the rod body of the first adjusting screw 33 located below the upper fixed support profile 31. The fastening nut 35 on the rod body of the first adjusting screw 33 can lock the screw after leveling to prevent loosening caused by vibration or external force and ensure the long-term stability of the leveling effect.
[0018] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
