Description

Technical Field

[0001] The present invention belongs to the technical field of multimedia teaching, and particularly relates to a label that can be used for multimedia teaching. Background Art

[0002] The same applicant disclosed in the patent document CN201811050785.8 "a multimedia teaching system, which includes: a vertically placed capacitive touch screen, and the backplane of the capacitive touch screen is an iron backplane; a main controller connected to the capacitive touch screen, and several labels. Among them, each label has its own unique identification code, and this identification code can be recognized by the main controller through the capacitive touch screen. Each label has a magnet, and when the label is placed on the screen surface of the capacitive touch screen, due to the action of the magnet, the label can be stably adsorbed on the capacitive touch screen. After the main controller recognizes the unique identification code of the label through the capacitive touch screen, multimedia information pushed by the display content box is displayed around the label on the capacitive touch screen."

[0003] This patent document further discloses that "the label has a plurality of metal sheets or metal columns, and the relative positions between the metal sheets or metal columns in each label are different. Denote the relative positions between the metal sheets or metal columns in each label as data F, then data F forms a corresponding relationship with the identification code of the label. The label also has at least one metal coil, and the metal sheets in the label are connected in series with the metal coil. The metal sheet or metal column is embedded in the bottom shell of the label." The structure of this label is as Figure 1 shown.

[0004] However, in practice, if the existing labels are used in multimedia teaching, since the teaching display screen is vertically placed, it is very difficult for the labels to be fixed on the screen of the touch display due to gravity, which affects the use in teaching. Summary of the Invention

[0005] The purpose of the present invention is to provide a label to solve the problem that it is not easy to stably place the label on the screen of the display in multimedia teaching.

[0006] One embodiment of the present invention is a label. There are a plurality of metal sheets or metal columns in the shell of the label, and the relative positions between the metal sheets or metal columns in each label are different. The label also has at least one metal coil, and the metal sheets in the label are connected in series with the metal coil. A first magnet is provided between the metal coil and the inner side surface of the bottom shell of the label. A silica gel film is attached to the outer side surface of the bottom shell of the label.

[0007] The label of the present invention and its use in a multimedia teaching system increase the friction of the label on the surface of the touch screen, better improve the tightness of the contact between the metal posts of the label and the screen, make the system more sensitive and accurate in identifying the label, and greatly enhance the use experience of using such labels for vertical touch display screens.

[0017] According to one or more embodiments, such as Figure 2 and 3As shown, a tag has multiple metal sheets or metal posts inside its housing, and the relative positions among the metal sheets or metal posts in each tag are different. The tag also has at least one metal coil, and the metal sheets in the tag are connected in series with the metal coil. A first magnet is provided between the metal coil and the inner side surface of the bottom housing of the tag. The backplane of the capacitive touch screen for teaching placed vertically is made of iron material. Due to the action of the magnet, the tag can be easily attracted and attached to the screen of the touch screen. The first magnet can be a circular magnet, and the metal coil can be a copper coil. The housing of the tag is sealed by a tag cover.

[0018] According to one or more embodiments, a silica gel film is attached to the outer side surface of the bottom housing of the tag. The function of the silica gel film is to increase the friction between the tag and the touch screen, preventing the tag from slipping off the screen.

[0019] According to one or more embodiments, the bottom housing of the tag is provided with a first opening, and the bottom of the first magnet falls into the first opening, so that the bottom surface of the first magnet and the outer side surface of the tag are in a plane. The function of the first opening is to make the first magnet closer to the screen surface of the touch screen.

[0020] According to one or more embodiments, the tag housing is provided with multiple metal posts, and the bottom housing of the tag is provided with multiple second openings corresponding to the positions of the metal posts. The silica gel film is provided with multiple third openings at corresponding positions, so that the bottoms of the metal posts can fall into the third openings through the second openings. The function of the metal post openings is to enable the metal posts to have better contact with the touch screen.

[0021] According to one or more embodiments, the metal post is in a T shape, and a T-shaped copper post can be used. The function of making it in a T shape is to prevent the metal post from falling off from the second opening by using the step of the metal post.

[0022] According to one or more embodiments, the tag housing is provided with multiple metal posts, and the tag housing is provided with corresponding hollow posts, so that the metal posts are installed in the hollow posts. A first spring is provided on the top surface of the metal post, and the first spring is pressed in the hollow post by a hollow post cover. The function of the first spring is to press the metal post against the bottom of the tag to ensure a better contact state with the touch screen. The function of the hollow post is to fix the spring, prevent it from moving left and right, and effectively prevent the spring from losing its function.

[0023] According to one or more embodiments, a multimedia teaching system includes: a vertically placed capacitive touch display screen, and the touch screen has an iron backplane; a main controller connected to the touch screen; and a plurality of tags. The tags have unique identification codes. When the tags are placed on the screen of the touch screen, they are attracted and held on the touch screen due to the action of magnets, and the identification codes are recognized by the main controller, and multimedia teaching content corresponding to the tags is displayed on the touch screen. The backplanes of the display screens on the market are all aluminum plates, and only the iron metal backplane can interact with the magnets inside the tags to ensure that the tags are stably placed on the vertical display screen.

[0024] In addition to having an iron backplane, the touch screen in this embodiment has a rear cover plate, a rear adhesive layer, a capacitive film, a front adhesive layer, and a front cover plate attached in sequence on the bare screen surface of the touch screen. The rear cover plate, the rear adhesive layer, the capacitive film, the front adhesive layer, and the front cover plate are all made of transparent materials. Among them, the front and rear cover plates are made of glass, the rear adhesive layer is coated with SOCA glue, and the front adhesive layer is coated with OCA glue. That is to say, the touch screen includes a display screen and a touch function layer.

[0025] It should be noted that although the foregoing has described the spirit and principle of the present invention in reference to several specific embodiments, it should be understood that the present invention is not limited to the specific embodiments disclosed, and the division of each aspect does not mean that the features in these aspects cannot be combined. This division is only for the convenience of expression. The present invention aims to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
