Description

Technical Field

[0001] The utility model relates to the technical field of smart blackboards, in particular to an infrared smart push-pull blackboard. Background Art

[0002] At present, the existing smart blackboards generally use writing screens, and the existing writing screens are generally capacitive writing screens, which have high maintenance costs. When maintenance is needed, it cannot be maintained on the client side, and the entire screen needs to be dismantled and brought back to the manufacturer for maintenance, and it is easy to be scrapped as a whole. Infrared writing screens are gradually being adopted in the field of smart blackboards due to their advantages such as low cost and low maintenance costs. For example, the patent number CN 218785891U discloses an infrared smart blackboard that can realize the display touch function of an all-in-one machine and the chalk writing function of an ordinary blackboard, but the chalk writing area is small and cannot meet teaching needs. Utility Model Content

[0003] In order to solve the problem in the prior art that the chalk writing area of ​​the existing infrared smart blackboard is small and cannot meet teaching needs, the utility model provides an infrared smart sliding blackboard, which integrates an infrared smart screen, a fixed sub-board and a sliding sub-board. It not only has the function of an infrared smart screen, but also takes into account the chalk writing area.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] An infrared intelligent push-pull blackboard, comprising:

[0006] Infrared smart screen, wherein a storage space for accommodating an infrared signal device is provided in front of the screen glass of the infrared smart screen;

[0007] at least one fixed sub-plate, the fixed sub-plate being biased forward relative to the screen glass;

[0008] The sliding sub-plate is arranged in front of the fixed sub-plate, and the sliding sub-plate slides back and forth to cover or display the screen glass.

[0009] Furthermore, the infrared smart screen includes a first frame, and the accommodation space includes an accommodation cavity provided on the first frame. The screen glass and the infrared signal device are both installed on the first frame, the structure is more integrated, and no additional frame for installing the infrared signal device is required. Moreover, the infrared signal device is installed in the accommodation cavity of the first frame, and will not be exposed, which is more beautiful.

[0010] Furthermore, the fixed sub-plate includes a second frame, and the second frame is aligned with the outer side of the first frame. The first frame and the second frame are aligned, which is more convenient for positioning. There is no drop between the first frame and the second frame, which is also convenient for installation of the push-pull sub-plate.

[0011] Furthermore, a slide rail is connected between the first frame and the second frame, and the push-pull sub-plate slides along the slide rail.

[0012] Furthermore, the first frame and the second frame are provided with threaded holes, the slide rail is provided with a round hole matching the size of the threaded hole and a plurality of waist holes corresponding to the positions of the threaded holes, the width of the waist hole matches the size of the threaded hole, and the length direction of the waist hole is parallel to the length direction of the slide rail. Positioning can be achieved by providing the round hole, and providing the waist hole can ensure a certain installation margin to prevent installation failure due to processing errors and the like, while the width of the waist hole matches the size of the threaded hole, and the length direction of the waist hole is parallel to the length direction of the slide rail, which ensures the relative position accuracy of the first frame and the second frame along the inner and outer directions.

[0013] Furthermore, the slide rail is provided with a slide groove, a slider is slidably arranged in the slide groove, an upper mounting plate is arranged on the upper end of the push-pull sub-plate, and the upper mounting plate is fixedly connected to the slider. The connection mode between the slider and the slide groove is easy to implement and has low cost.

[0014] Furthermore, the circular hole and the waist hole are located in the slide groove, the circular hole is a circular countersunk hole, and the waist hole is a waist-shaped countersunk hole. By providing the countersunk hole, the screw used for fastening can be hidden in the countersunk hole without interfering with the slider.

[0015] Furthermore, a lower mounting plate is provided at the lower end of the push-pull sub-plate, a limit block is fixed on the lower mounting plate, and the limit block abuts against the lower frame of the first frame or the second frame. The limit block cooperates with the slider and the slide rail to ensure the movement accuracy of the push-pull sub-plate.

[0016] Furthermore, the infrared signal device is arranged at the upper and lower ends of the infrared smart screen, which can ensure the normal operation of the infrared smart screen without the need to arrange the infrared signal device on the side of the screen, and the structure is easier to implement.

[0017] Furthermore, the push-pull sub-plate always covers the junction between the fixed sub-plate and the infrared smart screen during the sliding process. In this way, the gap between the fixed sub-plate and the infrared smart screen cannot be seen from the outside, which increases the overall aesthetics.

[0018] Beneficial effects:

[0019] (1) The infrared intelligent sliding blackboard of the utility model has an infrared intelligent screen, a fixed sub-board and a sliding sub-board at the same time. It has the function of an infrared intelligent screen and takes into account the chalk writing area. The fixed sub-board is biased forward relative to the screen glass. In this way, the height difference between the fixed sub-board and the sliding sub-board can be reduced, making writing more convenient.

[0020] (2) The distance between the fixed sub-plate and the push-pull sub-plate is small, the push-pull sub-plate will not shake during movement, and the movement accuracy is higher;

[0021] (3) The first frame and the second frame are aligned at their outer sides, and the fixed sub-plate is roughly aligned with the accommodating space. Thus, the fixed sub-plate is offset forwards by a distance relative to the screen glass, and the distance between the sliding sub-plate located at the outer side of the fixed sub-plate and the screen glass is relatively large, thereby preventing the sliding sub-plate from interfering with the screen glass;

[0022] (4) The writing screen of the utility model adopts an infrared smart screen and an infrared signal device, which is arranged in a receiving cavity on the front side of the upper and lower ends of the screen glass. When the infrared signal device needs maintenance, it only needs to be removed from the receiving cavity and taken to the manufacturer for maintenance, which makes maintenance more convenient;

[0023] (5) The slide rail can serve as a guide rail for pushing and pulling the sub-plate, and can connect the first frame and the second frame, and can also realize the positioning of the first frame and the second frame, ensuring that the outer side surfaces of the first frame and the second frame are aligned;

[0024] (6) The push-pull sub-plate always covers the junction between the fixed sub-plate and the infrared smart screen during the sliding process. In this way, the gap between the fixed sub-plate and the infrared smart screen cannot be seen from the outside, thereby increasing the overall aesthetics. BRIEF DESCRIPTION OF THE DRAWINGS
